Description
Technical field
The invention belongs to engineering construction safety protective equipment field, relate to a kind of vertical hoisting equipment safety landing door, special
Do not relate to the layer door of construction elevator in engineering construction and portal frame and hoist at hole top platform door.
Background technology
Current existing vertical hoisting transporting equipment generally hangs with vertical hoisting transporting equipment at the layer door of each stop stop
Larger gap is there is between cage door.Such as JGJ215-2010 " install, use, dismantle safe practice rule by building construction hoist
Journey " regulation cage door and stop exist in Appendix B gap cannot be greater than 50mm, JGJ88-2010 " portal frame and derrick material
Mine hoist safety technical specification " between the 6.2.2 article regulation stop layers platform outward flange and cage door, the gap of existence is not preferably greater than
100mm.Owing to the existence in this gap can cause the small dimension material of transport or small-sized work apparatus moving to stop transport from cage
Fall from gap time dynamic, thus cause security incident, and in practice of construction, between stop layers platform outward flange and cage door between
Gap is frequently more than above-mentioned regulation, causes potential safety hazard.
Simultaneously because the existence in above-mentioned gap, make plane between cage and stop discontinuous, cause workman being loaded by dolly
Material be the go-cart resistance and go-cart energetically overcoming gap to be formed when cage shifts to stop, cause stop and cage to be subject to
Greater impact load, produces potential safety hazard to stop and vertical hoisting transporting equipment.
It addition, existing construction elevator layer door or portal frame and the many employings of hoist at hole top platform door are by steel pipe, circle
Steel etc. are welded on the upper keeper made of layer every fan and carry out closed layer door, have that cutting of keeper material be big with welding job amount, work
The problem that skill is numerous and diverse, and the opening and closing of layer door is required to bimanualness, wastes time and energy, inefficiency, currently also has employing motor to drive
The mode of dynamic opening and closing layer door, but structure is complicated, manufacturing cost and energy consumption higher.
Summary of the invention
In order to solve the problems referred to above, the open a kind of vertical hoisting equipment safety landing door of the present invention, this safety landing door can have
Effect covers the gap of stop and vertical hoisting equipment room, eliminates safe hidden trouble, and reduces operator and set from vertical hoisting by material
The standby labor intensity to stop transfer, improves operating efficiency.
The technical problem to be solved realizes by the following technical solutions:
A kind of vertical hoisting equipment safety landing door, including doorframe and door leaf, about described door leaf each one, door leaf is movably set in
On doorframe, being band steel bottom described doorframe, connect an expansion board by articulating device bottom doorframe, this expansion board is turned over
Relay lower after can cover the gap between vertical hoisting equipment and layer door.
By bottom doorframe be flexibly connected an expansion board, can when needed expansion board be put down, cover layer door with execute
