Abstract

The utility model relates to the field of supporting equipment for bridge-type slewing cranes, in particular to an automatic connection device for a spreader, which is characterized in that it includes a rectangular sleeve and a T-shaped bar, and the near side wall of the rectangular sleeve is relatively provided with a pin hole. The rectangular sleeve is connected with the lifting beam of the crane through the pin shaft. There is a hole on the lower side of the pin hole. The direction of the groove on the walls of the two sides is opposite. Connected with the spreader, the diameter of the two ends of the T-bar matches the width of the slot. The bottom end of the rectangular sleeve is provided with a horn sleeve. Compared with the prior art, the beneficial effect of the utility model is: the device is used for the connection between the bridge crane and the spreader, can assist the crane to realize the operation of automatically removing and hanging the spreader, and saves non-working time and personnel who remove and hang the spreader , can significantly improve the operating rate of the crane.

Description

An automatic connecting device for a spreader

technical field

The utility model relates to the field of supporting equipment for a bridge-type slewing crane, in particular to an automatic connection device for a spreader.

Background technique

In the metallurgical industry, especially in steel rolling production units, bridge cranes are the main lifting equipment. They are used in production and equipment maintenance. The main task of the crane is to transport materials backward. According to the different shapes and specifications of materials, the spreaders used are Different spreaders are different, and different spreaders must be frequently replaced in actual work to meet the needs of production. Existing spreader removal and hanging is generally manual work, which increases non-operation time and personnel who remove and hang the spreader, and affects the crane operation rate.

Contents of the invention

The purpose of this utility model is to provide an automatic connection device for a spreader, which overcomes the deficiencies in the prior art, and is used for the connection between a bridge crane and a spreader, realizes the operation of automatically removing and hanging the spreader, saves non-working time and the need for removing and hanging the spreader Personnel, improve crane operation rate.

In order to achieve the above object, the utility model adopts the following technical scheme to realize:

An automatic connecting device for a spreader, comprising a rectangular sleeve and a T-shaped bar. Pin holes are oppositely provided on the wall of the near side of the rectangular sleeve. The rectangular sleeve is connected with the lifting beam of a crane through a pin shaft. There are holes on the side, and the directions of the grooves on the walls of the two sides are opposite. There is a T-shaped bar in the hole. The lower end of the T-shaped bar is connected with the spreader. match.

The bottom end of the rectangular sleeve is provided with a horn cover.

Compared with the prior art, the beneficial effect of the utility model is: the device is used for the connection between the bridge crane and the spreader, can assist the crane to realize the operation of automatically removing and hanging the spreader, and saves non-working time and personnel who remove and hang the spreader , can significantly improve the operating rate of the crane.

Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

See Fig. 1 to Fig. 3, which are schematic diagrams of the structure of an embodiment of an automatic connection device for a spreader of the present invention, including a rectangular sleeve 1 and a T-bar 2, and a pin hole 3 is oppositely provided on the proximal wall of the rectangular sleeve 1 , the rectangular sleeve is connected with the lifting beam 5 of the crane through the pin shaft 4, the underside of the pin hole 3 is provided with a slot 6, the direction of the slot 7 of the slot 6 on the cylinder wall on both sides is opposite, and the slot 6 is provided with There is a T-bar 2, the lower end of the T-bar 2 is connected with the spreader 8, and the diameter of the two ends of the T-bar 2 matches the width of the groove. In order to limit the swing angle of the T-bar 2 , a horn cover 9 is provided at the bottom of the rectangular sleeve 1 .

Under normal circumstances, the rectangular sleeve 1 is hung on the lifting beam 5 of the crane, and the T-bar 2 is connected with the spreader 8 . When it is necessary to hang the spreader on the crane, the crane lifts the crossbeam to the top of the spreader, the rectangular sleeve 1 is aligned with the T-shaped bar 2 and falls until the steel rope is under no force, and the two ends of the T-shaped bar 2 are placed along the rectangular sleeve. The wide distance side of the tube 1 enters, the crane lifts the beam 5 and rotates 90° clockwise, the rods at both ends of the T-shaped bar 2 slide into the slot along the slot, and are hung on the rectangular sleeve. At this time, the crane lifts the beam 5 rise, the spreader connection is completed. When picking off the spreader, the crane lifting beam 5 with the spreader falls to the state where the steel rope is not stressed, rotates 90° counterclockwise, and the two ends of the T-shaped bar 2 slide out of the opening, and the crane rises at this time. The rectangular sleeve is separated from the T-bar, and the removal of the spreader is completed.
