Description
技术领域 technical field
本实用新型属于石油机械或垂直升降电梯领域,特别是涉及一种提升设备的转动式防坠落装置。 The utility model belongs to the field of petroleum machinery or vertical lifting elevators, in particular to a rotating anti-falling device for lifting equipment.
背景技术 Background technique
目前,在石油开采设备,特别是具有配重垂直运动的抽油机,以及具有轿厢垂直升降电梯等提升设备中都需使用升降绳(钢丝绳或者钢带)提拉重物(配重或轿厢),由于提升作用的升降绳为易损件,长期重复的折弯卷绕等动作容易导致破裂,甚至断裂,同时当检修时需要将配重或者轿厢固定在某一位置,抽油设备现有技术中,常用的的处理方式有:使用支撑体将重物托起、使用长杆插销式的将重物卡在设备上,虽然一定程度上解决了坠落风险,但不能自行解除,需要人工进行拆除支撑体或者长杆。 At present, lifting ropes (wire ropes or steel belts) are required to lift heavy objects (counterweights or car lifts) in oil extraction equipment, especially pumping units with vertical movement of counterweights, and elevators with car vertical lifts. car), because the lifting rope is a vulnerable part, long-term repeated bending and winding actions are likely to cause rupture or even breakage. At the same time, it is necessary to fix the counterweight or the car at a certain position during maintenance. In the prior art, the commonly used handling methods include: using a support body to lift the heavy object, and using a long rod to lock the heavy object on the equipment. Although the risk of falling is solved to a certain extent, it cannot be released by itself. Manually remove the support body or long pole.
电梯中常使用安全钳紧急情况下进行制动,且当安全钳动作时往往会对电梯导轨和电梯轿厢造成一定的物理伤害,因此不可能在每次维修都通过安全钳的动作来将电梯轿厢固定于某一位置。插销式防坠落装置通过插销限制轿厢在竖直方向的自由度,使其可维持悬空状态。但插销在水平方向上的自由度并未受到限制,导致其在工作状态下仍不够稳定,一旦插销从锁孔中滑出,将发生严重事故。 Safety gear is often used in elevators to brake in emergency situations, and when the safety gear acts, it often causes certain physical damage to the elevator guide rails and the elevator car. Therefore, it is impossible to use the action of the safety gear to move the elevator car The box is fixed in a certain position. The bolt-type anti-fall device restricts the degree of freedom of the car in the vertical direction through the bolt so that it can maintain a suspended state. However, the degree of freedom of the bolt in the horizontal direction is not restricted, so that it is still not stable enough in the working state. Once the bolt slips out of the lock hole, a serious accident will occur.
