Description

Crane hook

Technical field：

The utility model is related to engineering recruitment appliance device field, more particularly to a kind of crane hook.

Technical background：

Iron builds suspension hook used on construction crane does not have auto-lock function, process of the weight sling in transport walking In, weight easily comes off from hook, the generation for causing the accident.Suspension hook structure at present with auto-lock function is more complicated, though Can so prevent weight from breaking off relations, but the suspension hook with auto-lock function all contains spring structure, and spring structure is susceptible to deformation, Service life is shorter, causes the maintenance cost of suspension hook.

The content of the invention：

In view of this, it is necessary to provide a kind of with auto-lock function and crane hook relatively simple for structure.

A kind of crane hook, including steel wire rope connecting portion, connecting seat, hook and hook self-locking device, the one of connecting seat End is fixedly connected with steel wire rope connecting portion, and the other end is fixedly connected with the upper end of hook, and hook self-locking device is fitted in hook Upper end, and positioned at hook and the junction of connecting seat, hook self-locking device includes balancing weight and stopper block, and one end of balancing weight sets U-shaped opening is put, the upper end of hook is sleeved at the U-shaped opening of balancing weight, and one end of stopper block is connected with the two ends of U-shaped opening.

Preferably, the two ends at the U-shaped opening of balancing weight open up pin shaft hole, and be connected with U-shaped opening the one of stopper block End opens up pin shaft hole, is passed through from the pin shaft hole of balancing weight and the pin shaft hole of stopper block using bearing pin, and balancing weight and stopper block are connected Connect.

Preferably, connecting seat includes the upper of left connection board, right connection board and lateral connection axle, left connection board and right connection board Lower two ends open up installing hole, and the upper end of hook is equipped with the installing hole of left connection board and the lower end of right connection board, steel wire rope connection Portion is a disc structure, and the center of steel wire rope connecting portion is equipped with the installing hole of left connection board and the upper end of right connection board, One end of lateral connection axle is fixedly mounted on the centre position of left connection board, and the other end is fixedly mounted on the interposition of right connection board Put.

The utility model is fitted on crane, stopper block will be closed at the opening of hook, and operative employee is new by this practicality The balancing weight of type is lifted, and one end of stopper block is close to the upper end of hook, is opened at the opening of hook, and weight is hung on hook, Operative employee puts down balancing weight, and stopper block sets back, and the opening of hook is closed.Thus, avoiding weight using the utility model Thing comes off from hook, and the utility model simple structure, is difficult to be damaged, and reduces the maintenance cost of suspension hook.

Description of the drawings：

Fig. 1 is the structural representation of crane hook.

Fig. 2 is the structural representation of balancing weight in Fig. 1.

Fig. 3 is the structural representation of stopper block in Fig. 1.

Fig. 4 is the structural representation of connecting seat in Fig. 1.

In figure：Steel wire rope connecting portion 10, connecting seat 20, left connection board 21, right connection board 22, lateral connection axle 23, hook 30th, hook self-locking device 40, balancing weight 41, stopper block 42.

Specific embodiment：

Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, crane hook includes steel wire rope connecting portion 10, connecting seat 20, hook 30 and hook self-locking device 40, one end of connecting seat 20 is fixedly connected with steel wire rope connecting portion 10, and the other end is upper with hook 30 End is fixedly connected, and hook self-locking device 40 is fitted in the upper end of hook 30, and positioned at hook 30 and the junction of connecting seat 20, hook Sub- self-locking device 40 includes balancing weight 41 and stopper block 42, and one end of balancing weight 41 arranges U-shaped opening, the upper end suit of hook 30 At the U-shaped opening of balancing weight 41, one end of stopper block 42 is connected with the two ends of U-shaped opening.

Two ends at the U-shaped opening of balancing weight 41 open up pin shaft hole, and one end being connected with U-shaped opening of stopper block 42 is opened If pin shaft hole, passed through from the pin shaft hole of balancing weight 41 and the pin shaft hole of stopper block 42 using bearing pin, by balancing weight 41 and stopper block 42 connections.

Connecting seat 20 includes left connection board 21, right connection board 22 and lateral connection axle 23, left connection board 21 and right connection board 22 upper and lower ends open up installing hole, and upper end and the installing hole of left connection board 21 and the lower end of right connection board 22 of hook 30 are matched somebody with somebody Dress, steel wire rope connecting portion 10 is a disc structure, the center of steel wire rope connecting portion 10 and left connection board 21 and right connection board The installing hole of 22 upper end is equipped with, and one end of lateral connection axle 23 is fixedly mounted on the centre position of left connection board 21, the other end It is fixedly mounted on the centre position of right connection board 22.

The utility model is fitted on crane, stopper block 42 will be closed at the opening of hook 30, and operative employee is by this reality Lifted with new balancing weight 41, one end of stopper block 42 is close to the upper end of hook 30, opened at the opening of hook 30, by weight Hang on hook 30, operative employee puts down balancing weight 41, stopper block 42 sets back, and the opening of hook 30 is closed.Thus, using The utility model avoids weight and comes off from hook, and the utility model simple structure, is difficult to be damaged, and reduces suspension hook Maintenance cost.
