The invention discloses a difficulty overcoming device of a construction lifter, and relates to the technical field of filters. In order to solve the technical problem that a device for simultaneously overcoming difficulties of a construction lifter with three motors and a contracting brake device is absent in the prior art, the difficulty overcoming device adopts a linked drawbar and a lengthened force arm connected with the linked drawbar, wherein the lengthened force arm comprises an extension rod; one end of the extension rod is equipped with a clamping unit; and the other end of the extension rod is equipped with a connecting head. The difficulty overcoming device solves the industry problem that three brakes of a national people-goods dual-purpose construction lifter are difficult in releasing and overcoming difficulties, realizes a safety way of simultaneously releasing and braking to overcome difficulties for the three brakes of the people-goods dual-purpose construction lifter, and solves a key technology of simultaneously releasing and braking for the three brakes incapable of unifying braking torque and the brake-releasing stroke in the prior art.
Description
technical field [0001] The invention relates to the technical field of lifts, in particular to a device capable of simultaneously unblocking a construction lift with three motors and a brake device. Background technique [0002] At present, a lot of construction elevators for people and goods are used in the construction process of high-rise buildings in China. Most of these construction elevators have three drive motors, and each motor is equipped with a normally closed brake. When working, three brakes work at the same time. At present, the release device for the dual-purpose construction elevators produced in China is not perfect. To move the brake release mechanism, you need to find a temporary crowbar and insert a handle to operate the brake release mechanism to release or release the brake. You must also tighten the brake release screws of other brakes in advance to release the brake. After the brake release screws are tightened It can no longer participate in braking...
