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 present invention relates to the technical field of elevators, in particular to a device capable of simultaneously solving a construction elevator with three motors and a holding brake device. Background technique [0002] At present, domestic dual-purpose construction hoists are used in high-rise building construction in a large number. This kind of construction hoist mostly has 3 driving motors, and each motor is equipped with a normally closed brake. When working, there are 3 brakes working at the same time. At present, the brake release device of the domestically produced dual-purpose construction lift is very imperfect. (Each drive motor is equipped with a handle lever release mechanism on the back cover. Because the handle is short, it cannot be pulled directly by hand. If you move the brake release mechanism, you need to find a temporary lever to insert a handle to operate the brake release mechanism to release or release the brake. You must also...
