Description

Transformer simple hoisting device

technical field

The invention relates to the technical field of electrical equipment installation, in particular to a simple hoisting device for a transformer.

Background technique

In the electrical equipment installation project, transformer installation is an indispensable content. Due to the large size and heavy weight of the transformer, transformer hoisting is often regarded as a key point of electrical equipment installation, which requires sufficient personnel and a long time to complete.

At present, tools such as cranes and chain reversing are used to install transformers in ordinary areas. There are many tools and it is inconvenient to carry, especially in mountainous areas where cranes are not easy to use, narrow places and the installation and disassembly of a single transformer. The cost of using cranes is too high due to terrain restrictions. , using a tripod (inconvenient to transport) and a hand hoist is too much work.

Contents of the invention

The technical problem to be solved by the present invention is to provide a simple transformer hoisting device for the above-mentioned existing technical deficiencies, which reduces manpower and material resources, and is suitable for transformer installation in various terrains. It is safe and fast, and the cost of consumption is low. The tools are easy to transport.

The technical solution adopted in the present invention is: a simple transformer hoisting device, including a fixed pulley and a winch, the fixed pulley is rotatably connected with the upper part of the electric pole by means of a hoop; a horizontal rotating arm is provided under the fixed pulley; The rotating arm is fixed on the electric pole by means of a hoop; the wire rope of the winch goes around the fixed pulley and the free end of the rotating arm.

Preferably, the rotating arm of the transformer simple hoisting device is provided with a telescopic rod, and the telescopic rod is slidably matched with the rotating arm and fastened by screws.

Preferably, the rotating arm of the transformer simple hoisting device is provided with a reinforcing arm; the two ends of the reinforcing arm are respectively hinged to the rotating arm and the pole.

The beneficial effects of the present invention are: using the electric pole as a lifting support, fixing the fixed pulley and the rotating arm on the electric pole, less tools and materials are used, and it is lighter, easier to carry and install than the traditional lifting device. When hoisting the transformer, the transformer can be quickly and accurately hoisted to the required position with the help of the winch and the rotating arm, which is safe and fast, and the cost of consumption is low.

Description of drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Among the figure, 1 fixed pulley, 2 electric poles, 3 hoops, 4 rotating arms, 5 reinforcing arms, 6 telescopic rods, 7 angle iron frames, 8 steel wire ropes, 9 hooks, and 10 winches.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1, the simple hoisting device for a transformer includes a fixed pulley 1 and a winch 10, the fixed pulley 1 is rotationally connected with the upper part of the pole 2 by means of a hoop 3; a horizontal rotating arm 4 is provided below the fixed pulley 1 The rotating arm 4 is fixed on the pole 2 by means of the hoop 3; the wire rope 8 of the winch 10 is bypassed from the fixed pulley 1 and the free end of the rotating arm 4.

To further optimize this embodiment, the rotating arm 4 of the simple transformer hoisting device is provided with a telescopic rod 6, and the telescopic rod 6 is slidably matched with the rotating arm 4 and fastened by screws.

To further optimize this embodiment, the rotating arm 4 of the transformer simple hoisting device is provided with a reinforcing arm 5; both ends of the reinforcing arm 5 are hinged to the rotating arm 4 and the pole 2 respectively.

The transformer simple hoisting device uses the pole 2 as a support for lifting, and the pole 2 itself also carries the installed transformer, and its strength is sufficient to support the weight of the transformer. In this way, it is not necessary to use a crane or a tripod and an inverted chain. For the terrain where a crane or a tripod is not easy to use, the simple lifting device of the transformer saves manpower and material resources to a large extent.

The swivel arm 4 can be turned over to the top of the transformer at first, and the transformer is hoisted to a suitable installation height by means of a wire rope; then the swivel arm 4 is turned to a position parallel to the angle iron frame 7 .

After the transformer reaches the appropriate installation height and is in the parallel direction of the angle iron frame 7, adjust the position of the telescopic rod 6, and drop the transformer on the appropriate position of the angle iron frame 7; Winch, when working, fix the hand winch firmly.

Since the rotating arm 4 not only receives the force in the direction of the vertical pole 2, but also receives the force parallel to the electric pole 2 downward, in order to ensure the firmness and stability of the vertical direction of the rotating arm 4, the reinforcing arm is hinged between the rotating arm 4 and the electric pole 2 5.
