Description

Special spreader for transformer disassembly and lifting

technical field

The utility model relates to a special spreader for disassembly and lifting of a transformer, which belongs to the technical field of lifting devices.

Background technique

When replacing or maintaining a transformer, it is often necessary to remove the transformer from high altitude or install the transformer on a corresponding support. Removal and installation of transformers usually requires the use of lifting equipment, which is a difficult operation. The main reason is that there are three fuses installed on the cross arm of the fuse on the transformer, the fuses extend upwards and outwards, the fuses are mainly composed of fragile porcelain parts, and are closer to the upper end of the transformer. The upper part of the hook of an ordinary crane is provided with a larger metal frame, and a pulley is housed in the metal frame. If the transformer is lifted with the hook of an ordinary crane, due to the position of the transformer, it is easy to touch the fuse crossarm or fuse by mistake during the lifting process, resulting in damage to the above-mentioned components; in addition, it is difficult to install the lifted transformer smoothly. To the specific location, the operation risk and the labor intensity of the operators are increased.

The above special spreader for transformer disassembly and lifting, the control lever is a folding structure, the control lever is composed of an upper control lever, a lower control lever, a supporting plate and a hinge, the upper and lower control levers are connected by a hinge, and the supporting plate is located on the upper , The lower part of the joint of the lower joystick, the supporting plate is fixed with the upper joystick.

The above special spreader for disassembling and lifting the transformer, the included angle α between the control lever and the support arm is 110°-160°.

The utility model designs a special lifting tool aiming at solving the lifting and placement problems of the transformer when disassembling and assembling the transformer. The special spreader includes a boom, two parallel arms arranged on the boom and a control rod connected with the boom. The front parts of the two support arms are provided with a support arm wire rope and a support arm hook, and the lower end of the control rod There is a control wire rope and a hanging ring on the boom. When the utility model is used, the hooks of the two arms respectively hook the lifting lugs on both sides of the transformer, and the hooks of the crane are connected to the hanging rings through the steel wire rope. It sits smoothly in place. By adopting the utility model, it is possible to prevent the hook of the crane from touching the cross arm of the fuse or the fuse by mistake, reduce the risk of action, and facilitate operators to install the transformer in place smoothly. In addition, the utility model has a simple structure and is easy to implement, and the folding design of the control rod is beneficial to the carrying and storage of the spreader.

Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model is a special spreader for transformer disassembly and lifting, which includes a boom 2 and a control rod 7, and the boom is fixedly connected with the control rod. Two support arms 1 are arranged parallel and symmetrically on the boom. The front part of each support arm is provided with a support arm wire rope 5, and the lower end of the support arm wire rope is provided with a support arm hook 6. The distance between the two support arms should be greater than or equal to The distance between the lifting lugs on both sides of the transformer to be lifted can avoid damaging the fuse on the upper part of the transformer when lifting the transformer. The top of boom 2 is provided with hanging ring 3, passes steel wire rope 4 in the hanging ring, and steel wire rope 4 is suspended on the suspension hook of crane. The joystick 7 is inclined downward relative to the support arm, and the lower end of the joystick is provided with a control wire rope 9 pulled by the operator. The above-mentioned structure of the spreader utilizes the principle of leverage, and the length of the control rod is much longer than the length of the support arm. The ground operator only needs to use a small force to control the transformer to be placed in place smoothly. For the convenience of operators, the angle α between the joystick 7 and the support arm 1 is 110°-160°.

Still referring to Fig. 1 and Fig. 2, in order to make the spreader suitable for lifting transformers of various specifications, a support arm hole 2-1 is provided on the support arm 2, and one end of the support arm 1 is provided with an external thread. The threaded end is set to be inserted into the hole of the support arm, and then the support arm and the boom are fastened by nuts. The support arm holes are symmetrically arranged on both sides of the boom, and there are 2-6 support arm holes. When in use, the position of the support arm can be adjusted according to the thickness of the transformer, so that the distance between the two support arms meets the requirement that it is greater than or equal to the distance between the lifting lugs on both sides of the transformer to be lifted.

Referring to Fig. 1 and Fig. 3, for the convenience of carrying and storage, the joystick 7 is designed as a folding structure, and the joystick is composed of an upper joystick 7-1, a lower joystick 7-2, a supporting plate 10 and a hinge 8, and the upper, The lower joystick is connected by a hinge, and the upper and lower joysticks can be opened as shown in Figure 1, and can also be folded as shown in Figure 3. The joystick is fixed. When the joystick is opened for use, the supporting plate acts as a limiter to ensure the use effect of the joystick.

The utility model can adjust the size of the relevant components according to the needs, so as to meet the hoisting requirements of the transformer stand.
