Abstract

The utility model discloses a lifer single door locking device which is used for the opening and closing of a construction lifter cage single door. The lifter single door locking device comprises the single door, a single door frame and a guard bar door frame. A single door locking device body is arranged between the single door and the guard bar door frame. A clamping base is fixed on the single door of the single door locking device body, a notch B is formed in the clamping base, the notch B is matched with one end of a lifting lever in shape and size, the lower end of the clamping base is provided with a slope A, the lifting lever is fixed to a fixing base on the single door frame through a fixing hinge pin, a stop lever is arranged on the fixing base, a shifting block is arranged on the guard bar door frame, and the side face of the shifting block is of a circular arc structure. When the single door is completely closed, one end of the lifting lever is right clamped into the clamping base, and the single door cannot be opened. When a cage lands, the lifting lever can be right pulled off from the clamping base through the shifting block, the single door can be pushed off upwards, and workers and goods can normally enter the cage. When a construction lifter works, the cage single door can be conveniently, rapidly and safely opened, the structure is simple and cost is low.

Description

Elevator single open-door door lock assembly

Technical field

The utility model relates to vehicle for construction technical field, specifically a kind of door lock assembly for construction elevator cage single open-door.

Technical background

For guaranteeing building hoist personnel's in operational process safety, require cage door before operation, external door (single open-door) must be in the lock state, and end of run, when cage lands, cage door can easily be opened, and effectively guarantees the normal folding of cage door.And existing door lock assembly adopts latch design, complex structure not only, aesthetics is poor, time-consuming, and degree of automation and safety factor extremely low.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of elevator single open-door door lock assembly, to realize the object of convenient and swift folding single open-door.

For achieving the above object, the utility model comprises single open-door, single open-door doorframe and divider gate doorframe, it is characterized in that: between single open-door and divider gate doorframe, single open-door door lock assembly is housed.

On the single open-door of described single open-door door lock assembly, be fixed with deck, on deck, have breach B, the shape of breach B and size are coincide with one end of driving lever, band inclined-plane, the lower end A of deck, driving lever is fixed on the permanent seat on single open-door doorframe by fixed pin shaft, on permanent seat, with pin, shifting block is contained on divider gate doorframe, and the side of shifting block is arc structure.

When the utility model single open-door is closed completely, one of driving lever just snaps in deck, can not be unlocked; When cage lands, shifting block can just be pushed driving lever aside in deck, and single open-door just can upwards be pushed open, and personnel and goods are are normally come in and gone out.Compared with prior art, in building hoist operational process, can be convenient, fast, the folding that guarantees safely cage single open-door, simple in structure, cost is low.

Fig. 2 is structure diagram of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises single open-door 1, single open-door doorframe 2 and divider gate doorframe 3, between single open-door 1 and divider gate doorframe 3, single open-door door lock assembly 4 is housed.On described single open-door 1, be fixed with deck 7, on deck 7, have breach B, the shape of breach B and size are coincide with one end of driving lever 6, band inclined-plane, the lower end A of deck 7, driving lever 6 is fixed on the permanent seat 5 on single open-door doorframe 2 by fixed pin shaft, and on permanent seat 5, with pin 9, shifting block 8 is contained on divider gate doorframe 3, the side of shifting block 8 is arc structure, and the effect of pin 9 is to limit the amplitude that shifting block 8 is stirred driving lever 6.

Close single open-door 1, driving lever 6 slips in the breach B of deck 7 by the inclined-plane A of deck 7, and driving lever 6 is snapped in the breach of deck 7, and single open-door is closed completely, and cage single open-door 1 is now locked, can not open.Upwards start elevator, personnel and goods are delivered to after designated floor, elevator starts downward operation.Now single open-door 1 is still in the lock state, and can not be unlocked.Continue operation downwards, when cage drops to lower position, be now arranged on the shifting block 8 on divider gate doorframe 3, just driving lever 6 is pushed aside in the bayonet socket of deck 7, single open-door 1 can upwardly open.
