Description

Technical Field

[0001] The utility model belongs to the technical field of transformer installation, in particular to a transformer installation hanger. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). When installing a pole-mounted transformer, it is necessary to use lifting equipment to hang it in the air and install the transformer overhead on the power pole.

[0003] Among them, after searching, it was found that there is an application number CN202020863047.1, which discloses a special lifting device for transformer installation, including a receiving base, and support plates are movably connected with bolts at the four corners below the receiving base, and universal wheels are fixedly connected to the inner sides of the four corner support plates, and a lifting piece and a fixing clamp are arranged. When the diesel generator is running and drives the electric winch to run to lower the wire rope through the pulley block, the fixing clamps on both sides are placed on both sides of the bottom of the transformer, and then the electric winch shrinks the wire rope. At this time, the fixing clamps on both sides will be tightened by the lifting piece and the rotating shaft under the influence of gravity, so that the transformer is firmly fixed between them and lifted and transported to the electric pole for installation, which saves costs and has strong practicality. A telescopic cross bar is provided, and two telescopic cross bars can be connected through the two telescopic cross bars according to transformers of different shapes, sizes and specifications. The return spring is stretched or shortened, so that the fixing clamps on both sides also expand or shrink through the rotating shaft following the extension and contraction of the two telescopic cross bars, so that transformers of different shapes, sizes and specifications can be clamped between the fixing clamps on both sides for hoisting and transportation, which further improves the practicability of the device. A shock-absorbing fixed base is provided. Since the diesel generator and the electric winch will generate severe vibrations during operation, the entire device will shake and the transformer cannot be hoisted well, which also makes the work safety poor. At this time, the shock-absorbing fixed base fixedly connected under the diesel generator and the electric winch can alleviate the vibration generated by the operation of the diesel generator and the electric winch through the spring shock absorbers at the four corners in the middle, thereby improving the stability and safety of the entire device, so that the transformer can be hoisted well.

[0004] However, after research, it was found that: the device cannot surround and fix the transformer, and the two sides are open, which may easily cause the transformer to slip and fall, and the safety of use is not strong enough. The device does not have a structure to fix the clamp and the pole. During the unloading process of the transformer, the wire rope is easy to rotate, causing the transformer to rotate, and there is no structure to actively unload the transformer. The unloading work of the transformer is difficult, so a new device is provided to solve this problem. Utility Model Content

[0005] The utility model aims to provide a transformer installation hanger in order to solve the above-mentioned problems of insufficient safety in use and inconvenience in unloading.

[0006] The technical solution adopted by the utility model is as follows: a transformer installation hanger, comprising a hanging frame, the hanging frame is arranged in a five-sided closed cube shape, and a baffle is slidably connected to one side of the opening of the hanging frame through a slide rail;

[0007] The interior of the hoisting frame is provided with a discharging mechanism for facilitating the discharging of the transformer.

[0008] Among them, the unloading mechanism includes rollers, servo electric cylinder C and push plates. Rollers are rotatably connected inside the lifting frame and at the exit of the lifting frame. A servo electric cylinder C is embedded and installed on the back of the lifting frame. The end of the servo electric cylinder C extends to the inside of the lifting frame and is fixedly installed with a push plate. A limit block is fixedly installed at the opening of the lifting frame corresponding to one side of the baffle. A pin plate is embedded and installed through a servo electric cylinder A at the opening of the lifting frame corresponding to the other side of the baffle. Servo electric cylinders B are embedded and installed on both sides of the lifting frame and in the middle of the baffle, and a fixed plate is fixedly installed at the end of the servo electric cylinder B.

[0009] Among them, servo electric cylinders D are symmetrically installed on the upper and lower sides of the lifting frame, and a fixing clamp is fixedly installed at the end of the servo electric cylinder D, and the fixing clamp is set in a U shape. Electric cylinders are symmetrically embedded and installed on both sides of the fixing clamp, and a clamp is fixedly installed at the end of the electric cylinder, and the clamp is set in an arc shape.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the utility model, through the unloading mechanism, the servo electric cylinder C extends to push the push plate to move, the push plate pushes the transformer to move, and the roller rolls with the movement of the transformer, reducing the friction between the transformer and the hanging frame, making the transformer unloading easier and more convenient.

[0012] 2. In the utility model, three servo electric cylinders B extend to push the fixing plates to clamp on three sides of the transformer, and cooperate with one side of the back of the lifting frame to firmly fix the transformer inside the closed lifting device formed by the lifting frame and the baffle, which surrounds the transformer in all directions, has a better fixing effect on the transformer, prevents the transformer from falling, and is safer to use.

[0013] 3. In the utility model, the fixing clamp is fixed on the power pole, so that the hanging frame is fixedly connected to the power pole, which prevents the hanging frame from rotating during the unloading process of the transformer, making the unloading of the transformer more stable.

The end of the servo electric cylinder C1031 extends into the inside of the hanging frame 1 and is fixedly installed with a push plate 1032.

[0025] When unloading is required, the servo electric cylinder C1031 extends, pushing the push plate 1032 to move, and the push plate 1032 pushes the transformer to move. The roller 103 rolls with the movement of the transformer, reducing the friction between the transformer and the lifting frame 1, making the transformer unloading easier and more convenient.
