Abstract

The utility model discloses an anti-rotating positioning device for a lifting hook. The device comprises a cross beam, a pin shaft, a pin, a plate shaped like a stop hook, a rectangular flat plate, a bolt with a groove, a J-shaped baffle plate, a locking slice with a key groove, an L-shaped plate and a lifting hook body, wherein a locking pad with the key groove is mounted on the lifting hook; the L-shaped plate and the J-shaped baffle plate are welded on the cross beam, so that the lifting hook and the cross beam are indirectly fixed together. The device is compact and reasonable in structure, and can be used for preventing the lifting hook from rotating during the operation process well. If the positioning device is lifted, the lifting hook can rotate flexibly. The device is favorable for the positioning of lifted articles. As a result, the whole lifting operation is safe and reliable.

Description

The anti-rotation registration device of a kind of suspension hook

Technical field

The utility model relates to the suspension hook group on a kind of hoisting crane, the anti-rotation registration device of especially a kind of suspension hook.

Background technology

At present general crane hook bearing part mainly is comprised of hook nut, pressure bearing, lifting beam with hook, suspension hook four parts, and compound type is that suspension hook passes crossbeam and bearing, is connected by screw thread and nut are intermeshing.When the suspension hook carrying object, gib head can freely rotate, simultaneously in the engagement process of crossbeam and suspension hook, if crossbeam and gib head gap are excessive, gib head also can produce certain cross travel, hangs loading easily and other object collision, hang in addition loading in place also more difficult, stability is bad, thereby for lifting the even danger of making troubles, has buried potential safety hazard to hoisting operation.

The utility model content

The purpose of this utility model is to provide the anti-rotation registration device of a kind of suspension hook, can overcome gib head rotational problems carelessly, and load-carrying capacity is high, conveniently hangs loading in place, safe and reliable.

The technical scheme that its technical matters that solves the utility model adopts is as follows:

The anti-rotation registration device of a kind of suspension hook, comprise crossbeam, bearing pin, pin, stop hook shape plate, rectangular flat plate, band slot bolt, J type baffle plate, band keyway stay, L-type plate, hook, one band keyway lock pad is installed on suspension hook, welding L-type plate and J type baffle plate, be fixed on suspension hook and crossbeam together indirectly on crossbeam.

On the described neck of hook with keyway lock pad installation suspension hook.

Between described stop hook shape plate and flat board, folder one L-type plate, wear three plates with bearing pin, and the lower end of intermediate plate can be stuck in the groove of lock pad.

Described J type baffle plate with the band slot bolt, is connected to baffle plate on flat board, and baffle plate can be stuck in the groove of stop hook shape plate just.

The utility model compact conformation is reasonable, can prevent well that load hook from rotating in operation process, can complete 90 ° of location of suspension hook head, if lift registration device, also can make the load hook flexible rotating, it is in place that this covering device is conducive to hang object carrier, makes whole lifting operation safe and reliable.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below by Figure of description, further set forth the utility model;

According to shown in Figure 1; The anti-rotation registration device of a kind of suspension hook; Comprise crossbeam 1; Bearing pin 2; Pin 3; Stop hook shape plate 4; Rectangular flat plate 5; Band slot bolt 6; J type baffle plate 7; Band keyway stay 8; L-type plate 9; Hook 10; One band keyway lock pad 8 is installed on suspension hook; Welding L-type plate 9 and J type baffle plate 7 on crossbeam 1; Suspension hook and crossbeam 1 have been fixed on together indirectly; Install on the neck of hook of suspension hook with keyway lock pad 8; Folder one L-type plate 9 between stop hook shape plate 4 and rectangular flat plate 5; With bearing pin 2, three plates are worn; The lower end of intermediate plate can be stuck in groove with keyway lock pad 8; J type baffle plate 7; With band slot bolt 6; Baffle plate is connected on rectangular flat plate 5; Baffle plate can be stuck in the groove of stop hook shape plate 4 just.

In the course of the work, before hoisting object, L-type plate 9 is being pressed J type baffle plate 7, and this covering device is in releasing orientation.

When hoisting object is located, L-type plate 9 is put down, be stuck in the groove with keyway lock pad 8, put down with J type baffle plate 7, be stuck in the groove of stop hook shape plate 4, so just pushed down L-type plate 9, device is in locking state, thereby suspension hook and crossbeam 1 have been fixed together, random rotation and the movement of suspension hook have been prevented, so easy gib head hoisting object of using makes easily also that to hang loading in place, and lifting operation is safe and reliable.

When the need of work suspension hook rotates, can lift J type baffle plate 7, L-type plate 9 is also lifted, registration device just is in releasing orientation like this, can rotate freely.

The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
