Description

Elevator falling prevention test detacher

Technical field

The utility model is related to a kind of falling prevention test device, especially a kind of elevator falling prevention test detacher.

Background technology

Elevator mentioned here is the building machinery for outer wall operation in architectural engineering, according to the relevant regulations of the state, It needs to carry out falling prevention test after the completion of design of hoist, whether the anti-fall safety for detecting elevator is reliable, usually needs The lifting utensil that detacher unclasp elevator is used to carry out drop shutter test, in the prior art, detacher takes off there are complicated Hook speed is slow, inconvenient for operation, and the small disadvantage of bearing load far can not meet the needs of elevator falling prevention test.

Utility model content

In view of the foregoing drawbacks, the utility model is mainly solving the technical problems that provide a kind of simple in structure, unhook speed Soon, the elevator falling prevention test detacher easy to operate, bearing load is big.

In order to solve the above technical problems, the technical solution that the utility model uses is：It is anti-fall to provide a kind of elevator Detacher is tested, including is fixed on the machine body fixed jaw, movable claw is distributed in the side of fixed jaw, and movable claw is hinged on body On, movable claw forms an opening either closed suspension hook, the other end of the movable claw with fixed jaw and is extended with first Swing arm, the end of the first swing arm are in contact with the end of second swing arm one end being hinged on body, the second swing arm Other end of outside be provided with axis pin, for stopping that the movement of the second swing arm, the axis pin are located at the work on body Dynamic slot, axis pin are matched by the shift fork being hinged on body, and shift fork is connected to operating lever.

In solution technique, the end face that the first swing arm is in contact with the second swing arm is designed as arcwall face, can be effective Reduce frictional force when carrying movement.

In solution technique, the vacancy portion for accommodating axis pin is distributed in shift fork, and axis pin is located in vacancy portion.

In solution technique, the loose slot is ring-type,

The utility model has the beneficial effects that：The elevator falling prevention test detacher of this spline structure has simple in structure, de- Hook speed is fast, the advantage easy to operate, bearing load is big.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model embodiment.

Fig. 2 is the working state schematic representation of the utility model embodiment.

The label of each component is as follows in attached drawing：1, body 2, fixed jaw 3, movable claw 4, suspension hook 5, the first swing arm 6, the second swing arm 7, axis pin 8, loose slot 9, shift fork 10, operating lever 11, weight.

Specific implementation mode

Below in conjunction with the accompanying drawings to embodiment further instruction.

As shown in Figure 1, in embodiment, elevator falling prevention test detacher, including it is fixed on fixed jaw 2 on body 1, it is fixed Movable claw 3 is distributed in the side of pawl 2, and movable claw 3 is hinged on body 1, movable claw 3 and fixed jaw 2 formed one open or Closed suspension hook 4, the other end of the movable claw is extended with the first swing arm 5, the end of the first swing arm 5 be hinged on The end of 6 one end of the second swing arm on body 1 is in contact, and the end face that the first swing arm 5 is in contact with the second swing arm 6 is set It is calculated as cambered surface, frictional force when carrying movement can be effectively reduced.

It is provided with axis pin 7 on the outside of second swing arm, 6 other end, the movement for stopping the second swing arm 6, because of suspension hook 4 under loaded state, and the first swing arm 5 can drive the second swing arm 6 to exert a force to side, and axis pin 7 plays the second swing arm 6 of blocking Effect, axis pin 7 is located in the loose slot 8 on body 1, and movement, shift fork 9 and behaviour are driven by the shift fork 9 being hinged on body 1 Make bar 10 to be connected.

In embodiment, the operating lever 10 as shown in Fig. 2, suspension hook 4 in the state of carrying weight, exerts a force, shift fork 9 is with axis pin 7 It is mobile, the second swing arm 6 being blocked is unclamped, to make the first swing arm 5 that movable claw 3 be driven to move, suspension hook 4 is made to open, weight Object 11 is completed to break off relations.

In embodiment, the first swing arm 5 and the second swing arm 6 can be designed on body according to the bearing load of suspension hook 4 Articulated position and length, to realize that shift fork 9 opens the larger suspension hook 4 of bearing capacity with smaller power.First swing arm 5 with Second swing arm 6 plays the role of lever.

In embodiment, the loose slot 8 is ring-type.

The elevator falling prevention test detacher of this spline structure has that simple in structure, unhook speed is fast, easy to operate, carrying is negative The big advantage of lotus.
