贵阳电梯维修厂家的电梯限速器安全钳的维护保养

Maintenance and maintenance of elevator speed limiter safety clamp of Guiyang elevator repair factory

电梯是载人的垂直交通工具,必须将安全运行放在首位。为保证电梯安全运行，从设计、制造、安装等各个环节都要充分考虑到防止危险的发生，并针对各种可能发 生的危险，设置专门的完全装置。限速器安全钳系统，就是在电梯发生超速和断绳时起保护作用的安全装置。该系统是否能正常工作，不仅取决于设计制造，更重要 的是取决于日常维护保养。

The elevator is a manned vertical vehicle, and the safe operation must be put in the first place. In order to ensure the safe operation of the elevator, we should take full account of the risk prevention and design from all aspects such as design, manufacture and installation, and set up a special complete device for all possible hazards. The speed limiter safety clamp system is a safety device that protects the elevator when it takes over and breaks the rope. Whether the system is able to work normally depends not only on the design and manufacture, but also on the daily maintenance.

国标GB7588-1997《电梯制造与安装规范》中第9.9.1条规定，操纵轿厢安全钳装置的限速器动作速度应发生在等于额定速度的115%。但应小 于：a)对于除了不可脱落式滚柱式以外的瞬时式安全钳装置的0.8m/s；b)对于不可脱落式滚柱式安全钳装置为1.00m/s；c)对于额定速度小于或 等于1.00m/s的渐进式安全钳装置为1.50m/s;d)对于额定速度大于1.00m/s的渐进式安全钳装置为1.25+0.25/v。对于额定速度 超过1.00m/s的电梯测定时建议按上述上限值的动作速度核定。第9.9.4条规定，限速器动作时，限速器绳的张紧力不得小于以下两个较大 者；a)300N，b)安全钳装置起作用所需力的两倍。

Article 9.9.1 of the national standard GB7588-1997 "elevator manufacturing and installation specification" stipulates that the speed limit of the speed limiting device for car safety clamp shall occur at 115% of the rated speed. But should be less than a) except for instantaneous safety gear can not fall off roller type except 0.8m/s; b) for the non shedding type roller type safety gear for 1.00m/s; c) for the rated speed of less than or equal to 1.00m/s progressive safety gear for 1.50m/s; d) on progressive safety pliers for rated speed of more than 1.00m/s 1.25+0.25/v. For elevator measurement with rated speed exceeding 1.00m/s, it is recommended that the action speed of the above upper limit value be approved. Article 9.9.4 stipulates that when the speed limiter moves, the tension of the speed limiter shall not be smaller than the two larger ones, and the a (300N) B shall have two times the power required by the safety clamp device.

用300N提拉力拉动安全钳连杆拉臂，整个机构动作灵活，连动开关也能同时动作。松开拉臂后，机构应能迅速回复，但联动开关不应复位。随着连杆机构运动，楔块应能在钳座内灵活滑动。正常情况下楔块与导轨侧工作面间隙应均匀，且应在2-3mm内。

Using 300N pulling force to pull the safety clamp connecting rod pull arm, the whole mechanism is flexible, and the connecting switch can also act at the same time. After the pull arm is loosened, the mechanism should be able to respond quickly, but the linkage switch should not be reset. With the movement of the connecting rod mechanism, the wedge should be able to slide flexibly in the clamp seat. Under normal conditions, the gap between the wedge and the working face of the guide side should be uniform and should be in the 2-3mm.

贵阳电梯维修厂家上述内容充分论述了限速器安全钳系统动作的必要条件和基本要求，但是，在对限器安全钳的检验中发现部分电梯由于维护保养不善，致使该安全装置根本达不到正 常的工作要求，主要存在下列问题：

Guiyang elevator repair factory above fully discussed the necessary conditions of speed governor safety action of the system and the basic requirements, but that due to poor maintenance in the elevator inspection of the limiter safety gear, the safety device did not reach the normal work requirements, mainly the following problems:

（1）、因限速器弹簧长期处于反复伸缩状态，使其整定动作速度改变；

(1) for a long time, the spring of the speed limiting device is in the state of repeated expansion, which makes the speed of the setting of the setting change.

（2）、转动部件长期缺油，阻力增大致使离心甩动部 分动作不灵活；

(2) when the rotating parts are short of oil for a long time and the resistance increases, the centrifugal movement is not flexible.

（3）、由于钢丝绳自身的变化延伸，造成张紧装置触地，使钢丝绳张力不够，发生打滑；

(3) because of the extension of the wire rope itself, the tensioning device touches the ground, so that the tension of the wire rope is not enough and skidding.

（4）、安全钳的连杆拉臂传动部分缺油、锈蚀，致使提 升力大大超过300N;

(4) the driving part of the connecting rod arm of the safety pliers is short of oil and corrosion, which makes the lifting force more than 300N.

(5)、主动杠杆末端与安全钳联动开关距离过大，拉臂提起时，开关不能同时动作；

(5) the distance between the end of the active lever and the linkage switch of the safety clamp is too large, and when the pull arm is lifted, the switch can not act at the same time.

（6）楔块与导轨侧工作面间隙过大，在连杆提起 进，楔块卡不住导轨；

(6) the gap between the wedge and the guide side is too large, and the connecting rod is lifted and the wedge can not be stuck to the guide rail.

（7）、楔块内油污过多，松开拉臂后楔块不能复位，造成导轨受损。这些问题的存在不仅使该系统成了摆设，而且容易使人产生心理麻痹， 潜在危害更大。因此，加强对限速器、安全钳的维护保养，防止重大事故的发生十分必要。

(7) too much oil in the wedge, which can not be reset after the loosening of the pull arm, resulting in the damage of the guide rail. The existence of these problems not only makes the system set up, but also makes it prone to psychological paralysis, and the potential harm is greater. Therefore, it is necessary to strengthen the maintenance of speed limiter and safety tongs to prevent the occurrence of major accidents.

具体地说应该做好以下两点：

In particular, we should do the following two points:

（1） 限速器要勤检查。旋转轴销，张紧装置轮轴与轴套每周应挤加钙基润滑油一次。张紧装置的张力应一致，旋转轴销部分每周注油一次，每年清洗一次，铅封处不得拆 卸，离心甩动装置应定期清理上油，保持动作灵活。限速器的绳索伸长超出规定范围时，应截短绳索。每2年要经有关部门校验1次限速器动作速度，确保其动作速 度在国家标准规定的范围内。

(1) the speed limiter should be inspected frequently. The rotating shaft pin and the shaft and sleeve of the tensioning device should be filled with calcium base lubricating oil once a week. Tensioning device of rotating shaft pin tension should be the same, part of a weekly oiling, washed once a year, the seal shall not disassemble, centrifugal device should be cleaned regularly to keep oil, flexible action. When the rope elongation of the speed limiter exceeds the specified range, the rope should be truncated. Every 2 years should be checked by the relevant departments to check the speed of the 1 speed limiter, to ensure that the speed of its action is within the limits prescribed by the national standard.

（2）安全钳、连杆机构每月应加机油润滑1次，同时紧固，保证提拉力迅速传递到安全钳拉杆上，且不超过300N。调整松动的弹簧、螺钉、销轴等零件。楔块、钳座每月涂少量凡士林1次。定期清洗调整安全钳楔块，清除里面沉积的油污，保证钳块的动作灵活。

(2) the safety pliers and linkages should be lubricated 1 times a month and fastened at the same time to ensure the rapid transfer of pull force to the safety clamp rod, and not more than 300N. Adjust the loose springs, screws, pin shaft and other parts. A small amount of Vaseline was painted 1 times a month.  Regular cleaning and adjusting the safety clamp wedge to remove the oil from the inside, so as to ensure the flexible movement of the clamp block.

总之。限速器安全钳系统是电梯的1个十分重要的安全装置，其动作正常与否不仅关系到电梯本身的运行安全，更关系到人们的生命及财产的安全。因此，电梯使用 单位加强对该安全装置的维护保养十分必要。同时，电梯监督与检验机构也必须加强对电梯的安全管理，特别要加强对电梯安全装置的检验与试验，从而保证电梯安 全，高效地运行。

In a word. Speed governor safety tong system is the 1 most important safety device of elevator. Its normal operation is not only related to the safety of the elevator itself, but also to the safety of people's lives and property. Therefore, it is necessary to strengthen the maintenance and maintenance of the safety device by the use of the elevator unit. At the same time, the elevator supervision and inspection organization must also strengthen the safety management of the elevator, especially to strengthen the inspection and test of the elevator safety device, so as to ensure the safe and efficient operation of the elevator.
