Through holes for bolts.

Compared with the prior art, the beneficial effects of the spreader of the present invention are:

1. The sling of the utility model uses a motor to drive the reel to lift the on-load tap changer or transformer hung on the hook.

2. The spreader of the utility model has only a few supporting parts and transmission parts, so it has simple structure, small volume and flexible operation.

3. In a preferred embodiment of the present invention, the boom can rotate horizontally through the cooperation of the bushing and the post, so that the on-load tap changer or transformer on the hook can be moved to a suitable position for easy maintenance or replace etc.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1-Fig. 4, the embodiment of the utility model discloses a kind of sling, which is used for hoisting on-load tap changer, transformer and the like, and the sling includes a mounting seat fixed on a fixed foundation 10. A column 20 with a circular cross-section that is vertically fixed on the mounting base 10 by welding, the first end is connected to the upper end of the column 20, and the boom 30 arranged horizontally, and the motor 40 installed at the second end of the boom 30 , the reel 50 that is installed on the output shaft of the motor 40 and rotates coaxially with the output shaft, the suspension rope 60 wound on the reel 50 and the suspension hook 70 connected with the free end of the suspension rope 60 . The drive motor 40 drives the reel 50 to rotate through the output shaft, and the reel 50 drives the on-load tap changer, transformer and the like on the hook 70 to move up and down through the suspension rope 60 to realize the on-load tap changer, transformer and the lifting of its analogues.

In order to move the on-load tap changer, transformer and the like to a suitable position for maintenance or replacement, in a preferred embodiment of the present invention, the upper end surface of the column 20 is coaxially fixed with a plug with a circular cross-section. column 21, the diameter of the inserted column 21 is smaller than the diameter of the column 20, so that the connection between the inserted column 21 and the column 20 forms a step, the first end of the boom 30 is fixedly connected with a sleeve 31, and the axial direction of the sleeve 31 is in line with the column 20. The length direction of the boom 30 is vertical, and the casing 31 is sleeved on the post 21 and abuts against the step. In this way, the bushing 31 rotates relative to the post 21, so that the boom 30 can rotate horizontally around the post 20, so that the OLTC, transformer and the like on the hook 70 can move horizontally.

The mounting seat 10 in the hanger of the present utility model can have various structures, any structure that can play a supporting role and can be installed on a fixed foundation can be used. In a preferred embodiment of the present utility model, the mounting seat 10 includes a plate-shaped The mounting base body and the mounting portion fixedly connected to the mounting base body for detachable connection with the fixed base, the column 20 is fixed on the mounting base body.

Usually, there is a fixed base on the periphery of the on-load tap changer that facilitates the fixing of the mounting seat 10 (the fixed base is actually other equipment existing around the on-load tap changer), and the fixed base has multiple bolt mounting holes, and multiple bolts The mounting holes are circular or arc-shaped, so that the mounting base 10 can be fixed on the fixed base, as shown in Figure 4, the mounting portion of the mounting base 10 is an arc-shaped plate 13, and one of the side plates of the mounting base body For the arc-shaped side matching with the arc-shaped plate 13, the arc-shaped plate 13 is fixed on the arc-shaped side of the mounting seat body, and an arc for passing the bolt 12 is provided along the arc-shaped direction of the arc-shaped plate 13. Shaped elongated hole 131, the radius of this arc-shaped elongated hole 131 is the same as the radius determined by the arc of a circle of bolt mounting holes on the fixed foundation, so, the bolt 12 that passes through the bolt mounting hole and arc-shaped elongated hole 131 will mount the seat 10 is fixed on the fixed foundation so that the on-load tap changer is hoisted.

There is also a fixed foundation on the periphery of the transformer that facilitates the fixing of the mounting base 10 (the fixed foundation is actually other equipment that exists around the transformer), and the fixed foundation has two parallel fixed plates. The steel 11 is used as the mounting part of the mounting base 10. Specifically, as shown in Figures 1 and 2, two channel steels 11 are respectively fixed on the bottom of the mounting base body by welding one of its respective wing plate openings, and the other wing plate Through holes for passing bolts 12 are opened respectively, and the channel steel 11 and the fixing plate are fixed by the bolts 12, thereby fixing the mounting base 10 .
