Description
Technical Field
The utility model relates to the field of construction elevators, in particular to a guardrail door locking device of a construction elevator.
Background
The construction elevator is generally used in building construction and is responsible for vertical transportation of people and goods. Due to the unique box body structure, the bicycle is comfortable and safe to ride. The bottom fence is used for isolating the construction hoist from the peripheral area of the construction hoist, and the use safety of the construction hoist is guaranteed.
At present, a guardrail door lock of a construction elevator is generally characterized in that a lock plate is welded on a guardrail door and a guardrail door frame respectively, and the lock plate protrudes out of the guardrail door and the guardrail door frame. The door lock mode has high requirements on the relative position matching of the guardrail door lock plate and the guardrail door frame lock plate, and has high manufacturing difficulty and high cost. Simultaneously because the jam plate protrusion, the damage of colliding with very easily in the equipment transportation to cause the guardrail door can't lock.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides the guardrail door locking device of the construction elevator, which is simple to manufacture, low in cost, not easy to damage and good in using effect.
In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides a guardrail lock door device of construction elevator, includes guardrail door and guardrail door frame, be equipped with guardrail door guide pulley otic placode on the guardrail door, the guardrail door frame includes guardrail door frame riser, all is equipped with the lockhole that is used for installing the lock on guardrail door frame riser and the guardrail door guide pulley otic placode to the position of lockhole is higher than the position of lockhole on the guardrail door totally closed back guide pulley otic placode on the guardrail door frame riser.
In the technical scheme, the guardrail door is provided with the electric limit switch, and the vertical pipe of the guardrail door is provided with the limit groove.
The utility model has the beneficial effects that:
1. the matching requirements of the guardrail door and the door frame and the door lock are reduced, the manufacturing difficulty of the guardrail door and the guardrail door frame is reduced, and the manufacturing cost is reduced;
2. the door lock does not protrude out of the guardrail door and the guardrail door frame, so that the transportation, collision and deformation are avoided;
3. when the guardrail locks the door, the guardrail door is raised, the electrical limit switch acts, the construction elevator is powered off, the power consumption is reduced, and the service life of the electrical element is prolonged.
