A space obstacle intercepting device for a mechanical construction hoist

Abstract

The invention discloses a space obstacle intercepting device for a mechanical building hoist, which includes a car and a driving mechanism, wherein the driving mechanism includes a power device and a control loop used for controlling the power device to start and stop; a travel switch is arranged on the car and includes a control circuit, and contacts used for switching-on or switching-off the control circuit; the travel switch is used for switching on / off the control loop; the car is further provided with sliding rods moving relative to the car in the lifting direction of the car; one ends of the sliding rods can be contacted with the contacts on the travel switch, and the other ends of the sliding rods extend out of the space above and / or below the car. According to the invention, when the car is to directly hit against an obstacle, the power is cut off, the car is prevented from hitting against the obstacle under the function of the driving force, and the safety performance is better.

Description

technical field [0001] The invention relates to a safety protection device for a construction elevator, in particular to a space obstacle intercepting device for a mechanical construction elevator. Background technique [0002] With the continuous development of the construction industry, more and more construction elevators are used in construction construction. Construction elevators are also called construction elevators. They are usually composed of car, drive mechanism, standard section, attached wall, chassis, fence, electrical system, etc. It is partly composed of manned and cargo-carrying construction machinery often used in construction. Along with this, the demand for the safety guarantee of construction elevators is constantly increasing, especially for the construction elevator space obstacle interception safety device, which is an urgent need for safety devices at present. The main shortcomings of the existing construction elevators are: [0003] The constructi...

AI Technical Summary

Problems solved by technology

[0003] The construction elevator lifts and passes through the outside of the building, and it is easy to collide with the obstacles protruding from the upper and lower floors of each floor. and because the construction staff between the upper and lower floors of each floor often stick their heads out to the outside of the floor, it is very easy for the elevator in operation to be scratched, causing personal injury, and it is urgent to develop a construction elevator. space obstacle interception device
