Abstract

The utility model relates to a decoupling prevention safe device of a crane. The bar part of a hook is connected with an anchor ear. The ear of the anchor ear is connected with a bend angle through a pin. The bend angle can swing along the pin. The two feet of the bend angle face downwards. One end of the bend angle is supported on the inner side of the tip of the hook and the other end of the bend angle is connected with a heavy weight. The working process is as follows: a rope which is tied with goods overcomes the gravity action of the heavy weight and is sleeved in the hook. Under the gravity action, one end of the bend angle is supported on the inner side of the tip of the hook. Thus, the rope can not be detached from the hook to play a role of safety protection. The decoupling prevention safe device of the crane has the beneficial effect that with the decoupling prevention safe device of the crane of the utility model used, the heavy weight can not be detached from the hook and no equipment damages or personnel casualty accidents can be caused.

Description

Hoisting crane lock hook safety device

Affiliated technical field

The utility model relates to hoisting crane lock hook safety device.

Background technology

At existing crane hook, the lock hook device is not set, in the course of the work, the rope that hangs weight might cause device damage or personnel casualty accidents from landing on the suspension hook.

The utility model content

The purpose of this utility model is that hoisting crane lock hook safety device is provided in order to address the above problem, and in the course of the work, the rope that hangs weight can not cause device damage or personnel casualty accidents from landing on the suspension hook.

The technical scheme that its technical matters that solves the utility model adopts is: at anchor ear of bar portion bolt together of suspension hook, on the ear of anchor ear, connect a bent angle with bearing pin, bent angle can be swung along bearing pin, the bipod of bent angle down, one end of bent angle is against the bill inboard of suspension hook, and the other end of bent angle connects a weight.Its working process is such: when being that the action of gravity that has the rope of goods to overcome weight is enclosed within the suspension hook, and by gravity, an end of bent angle is against the bill inboard of suspension hook, is unlikely to make rope slippage in the suspension hook, has played the safety precaution effect.

Effective effect of the present utility model is, uses hoisting crane lock hook safety device of the present utility model, and the rope that hangs weight can not cause device damage or personnel casualty accidents from landing on the suspension hook.

Description of drawings

Figure is the structural representation of hoisting crane lock hook safety device of the present utility model.1-suspension hook among the figure, 2-weight, 3-bent angle, 4-bearing pin, 5-suspension hook bar portion, 6-anchor ear, 7-bolt.

The specific embodiment

Connect an anchor ear (6) in suspension hook bar portion (5) with bolt (7), on the ear of anchor ear (6), connect a bent angle (3) with bearing pin (4), bent angle can be swung along bearing pin (4), the bipod of bent angle (3) down, one end of bent angle (3) is against the bill inboard of suspension hook (1), and the other end of bent angle (3) connects a weight (2).Its working process is such: when being that the action of gravity that has the rope of goods to overcome weight (2) is enclosed within the suspension hook (1), by gravity, one end of bent angle (3) is against the bill inboard of suspension hook (1), is unlikely to make rope slippage in the suspension hook, has played the safety precaution effect.

Claims

1, hoisting crane lock hook safety device, it is characterized in that: at anchor ear of bar portion bolt together of suspension hook, connect a bent angle with bearing pin on the ear of anchor ear, the bipod of bent angle down, one end of bent angle is against the bill inboard of suspension hook, and the other end of bent angle connects a weight.
