Description

Technical Field

[0001] The utility model relates to the field of coating machine devices, in particular to a transformer hoisting device. 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. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. According to their uses, they can be divided into power transformers and special transformers (furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, medium frequency transformers, high frequency transformers, impulse transformers, instrument transformers, etc.);

[0003] In recent years, with the continuous development of society, my country's electricity consumption has been growing rapidly, and the demand for transformers has increased. However, there are certain risks in the process of transformer hoisting. For example, the uneven weight of most transformers makes hoisting easy to cause risks, and the marking of positioning holes during installation is slow, resulting in low installation efficiency. This has created a great demand for transformer hoisting devices.

[0004] At present, when hoisting transformers, most of them are hooked directly on the hook holes that come with the transformer when it leaves the factory, and then hoisted with a crane. During the hoisting process, since the center of gravity of most transformers is asymmetrical, they are generally a structure with one end heavy and the other end light, which may cause the transformer to fall over during the hoisting process, causing loss of life and property. Secondly, when hoisting to the designated location for installation, it is necessary to manually locate the installation holes, and then drill expansion bolt holes on the installation base. Finally, the transformer is lowered and fixed with expansion bolts. However, due to the hoisting, the transformer will shake, and workers cannot quickly locate and drill holes, resulting in low installation efficiency.

[0005] Therefore, it is necessary to propose a transformer lifting device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a transformer hoisting device to solve the problems proposed in the above background technology that the transformer has an asymmetric center of gravity and is generally a structure with one end heavy and the other end light, which may cause it to fall over during the hoisting process and the positioning holes cannot be quickly positioned and punched due to the shaking of the transformer when marking the positioning holes, resulting in low installation efficiency.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a transformer hoisting device, comprising a hoisting top plate, wherein the hoisting top plate is provided with a through slot, wherein two through slots are axially symmetrically distributed on the hoisting top plate, wherein a plurality of rod insertion holes are provided in the through slots, wherein the plurality of rod insertion holes are evenly distributed in the through slots;

[0008] A fixing block is installed in the through slot, and a fixing block hole is opened on the fixing block, and the fixing block hole passes through the fixing block;

[0009] A hanging rod is installed inside the fixed block, and a hanging hole is opened on the hanging rod. There are multiple hanging holes, which are evenly distributed on the hanging rod. A hook is fixedly installed on the lower surface of the hanging rod, and a rotating column is installed on the upper surface of the hanging rod, and a hanging ring is installed on the rotating column;

[0010] Limiting grooves are provided on both sides of the hoisting top plate. There are a plurality of limiting grooves evenly distributed on the hoisting top plate. Rod insertion holes are provided in the limiting grooves. Rods are inserted into the rod insertion holes. Limiting blocks are installed on the rods. Pull-out pieces are installed on the limiting blocks. Limiting holes are provided on the pull-out pieces.

[0011] A positioning plate is fixedly installed near both sides of the lower surface of the hoisting top plate, and a fixing hole is opened on the positioning plate. There are multiple fixing holes, which correspond to the lower part of the limiting groove. A limiting column is clamped in the fixing hole. A pulley groove is opened on the positioning plate, and a pulley is slidably installed in the pulley groove. There are two pulleys, and a cylinder is installed between the pulleys, and a rope is installed on the cylinder;

[0012] A conical piece is installed at the lower end of the rope, a liquid cavity is opened on the conical piece, and a liquid outlet is opened at the lower end of the conical piece.

[0013] Preferably, an upper vibration isolator is installed at the center of the lower surface of the hoisting top plate, a damping spring is installed in the upper vibration isolator, and a lower vibration isolator is installed at the lower end of the damping spring.

[0014] Preferably, the insertion rod passes through the fixing block hole, the hoisting hole and the insertion rod hole.

[0015] Preferably, the limiting block is located in the limiting groove.

[0016] Preferably, the limiting column passes through the limiting hole and is located in the fixing hole.

[0017] Preferably, a transformer to be hung is hung below the hook, and bolt holes are installed on the transformer to be hung.

[0018] The technical effects and advantages of this utility model are:

[0019] 1. The hoisting holes, rod insertion holes, fixing blocks and rod insertion holes provided in the present invention can be moved forward and backward inside the through slot by the fixing blocks, so as to hoist transformers of different lengths. Moreover, by adjusting the front and back, transformers with asymmetric centers of gravity can also be stably hoisted. For example, if the transformer is front-heavy and back-light, the first rod can be inserted into the frontmost rod insertion hole, and the second rod can be inserted into the penultimate rod insertion hole. Stable hoisting is achieved by adjusting the center of gravity, which increases the applicability and safety of the device and solves the problem of tipping due to asymmetric center of gravity during hoisting.

[0020] 2. The rope and conical member provided in the present invention are straightened due to gravity after being hoisted to the designated position, so that the staff can use the conical member to roughly position it. When it is moved to the mounting base, the conical member is placed in the bolt hole, and water or other liquid is added. It flows out through the liquid outlet and drips onto the mounting base. The bolt hole can be quickly positioned and the expansion bolt hole can be drilled, which solves the problem of not being able to quickly locate the hole during installation and improves work efficiency.
