Description

A kind of elevator system, which attaches together, puts

Technical field

The utility model belongs to elevators field, and particularly a kind of elevator system, which attaches together, puts.

Background technology

In current elevator accident, more than half is caused by door system failure, and therefore, new standard GB7588 the 1st is repaiied Change list, it is desirable to which increase is anti-to take off door gear, i.e., also needs to increase a set of latch hook device as with layer door, on gate.Latch hook is by opening Door knife on door machine is moved to drive the wheel actions on layer door so as to complete unhook action, and current door lifter exists simultaneously Main door knife and the secondary covering device of door knife two are respectively cooperating with the action of layer door lock hook and gate latch hook.Every layer increases a set of roller devices Meanwhile increase secondary door knife by main door knife to coordinate the action of the roller, due to foozle, hoistway error, assembling mistake be present The factors such as difference, cause the installation, adjustment, maintenance of follow-up elevator door to work and be multiplied, related safety clearance is difficult to adjust It is whole to arrive design requirement；Old ladder is transformed after particularly, to adapt to new standard, all layer Men Mentou are both needed to change, in the past The layer Men Mentou produced will go out of use, and cause to waste, add enterprise into production cost；Meanwhile elevator is closed the door normally During operation, the left and right door cutter position of major and minor door knife is fixedly connected by linkage, it is impossible to self-adjusting, is gone out when because of fortuitous event When existing left and right directions door knife encounters the fixed idler whell on layer Men Mentou, there will be the potential safety hazard for breaking a knife or layer door lock.Cause This, at present structure to have that complicated, mounting and adjusting is cumbersome, cost is high, space-consuming is big, security is poor etc. many it is insufficient with it is scarce Fall into.

The content of the invention

The purpose of this utility model be to provide a kind of scientific structure design rationally, meet Standard, convenient installation, drop Low product cost, improve packaging efficiency, safety and stability, the elevator system that is easily achieved attach together and put.

The utility model solves its technical problem and is achieved through the following technical solutions：

A kind of elevator system, which attaches together, puts, including mounting base, first knife and second knife, it is characterised in that：Also include turning Arm, latch hook, the first extension spring and the second extension spring, the pivoted arm of rotational installation is longitudinally evenly equipped with described mounting base, at each turn The left end of arm is provided with first knife jointly, and second knife is provided with jointly in the right-hand member of each pivoted arm, in second knife Latch hook is provided with by axis of rotation on the mounting base of right side, the bearing of latch hook left end is meshed with the side end face of second knife, The right-hand member of latch hook and the lock hook seat phase hook on door machine fill, and a connecting rod are provided with described latch hook, the connecting rod is with consolidating The the first extension spring connection being scheduled on mounting base, the first extension spring are connected with the second extension spring being fixed on first knife.

Moreover, described pivoted arm is 2-6.

Moreover, described pivoted arm is straight type pivoted arm.

Moreover, described first knife and second knife is connected by the axle that presses with pivoted arm.

The advantages of the utility model and have the beneficial effect that：

Put 1. an elevator system attaches together, while the installation, adjustment, maintenance for not changing existing elevator door work, Original layer of door door header structure and size are kept, is attached together and is put to realize the dynamic of layer door lock hook and gate latch hook using a set of elevator system Make, meet new standard requirement, meanwhile, synchronously opening for layer door and gate is realized by the linkage of first knife and second knife Open；When the elevator is run, even if encountering fixed idler whell on layer Men Mentou because left and right directions door knife occurs in fortuitous event, door is utilized The self-adjusting function of knife, avoid the destruction of a knife or layer door lock and accident occur, greatly improve security reliability.

2. the utility model scientific structure design is reasonable, have meet Standard, interchangeability are strong, reduce product cost, Packaging efficiency, safety and stability, the advantages of being easily achieved are improved, is that a kind of elevator system with higher innovation attaches together and put.
