Description

Lifting device for power supply facility

technical field

The utility model relates to lifting equipment for power supply facilities.

Background technique

Power supply construction often needs to lift the equipment to a high place for installation. At present, some large-scale lifting devices, such as cranes, are commonly used to complete the lifting work. When the construction environment is narrow and large-scale equipment such as cranes cannot enter, it will bring difficulties to the equipment installation. When using a crane for lifting work, in order to avoid the safety risks caused by using the crane during live work, it is necessary to cut off the power of the equipment before lifting, which will affect the normal life and production of surrounding residents and users.

Utility model content

The technical problem to be solved by the utility model is to realize a device capable of hoisting and constructing power supply facilities under electrified conditions.

In order to achieve the above object, the technical solution adopted by the utility model is: a lifting device for power supply facilities includes a fixed bracket and a pulley block, the fixed bracket is fixed on the top of the utility pole, and the pulley block includes a fixed pulley, a movable pulley and a pulley that cooperate with each other. A stay rope, the fixed pulley is fixed on the fixed bracket, the movable pulley is connected to the hoisted equipment, and one end of the stay rope extends to the ground.

The fixed bracket is composed of two right-angled triangular brackets connected with each other through fixed rods, one side of the fixed bracket is fixed on the top of the utility pole through a detachable fixing ring, and the acute-angled end of the other side of the right-angled side is provided with a A pulley block installation shaft is arranged, and the fixed pulley is fixed on the installation shaft.

The pulley block includes a fixed pulley fixed on the fixed bracket, a movable pulley provided with a hook for hoisting equipment, and a stay rope, one end of the stay rope is fixed on the fixed pulley, and the stay rope After surrounding the movable pulley and the fixed pulley in turn, its other rope end extends to the ground.

Both the fixed bracket and the block of pulleys are insulating parts.

The utility model has the advantage that the lifting device can be used for lifting power supply facilities under electrified conditions, and when working in a narrow space environment, when heavy lifting equipment cannot enter, the device can also be used for lifting, which is widely used. The device has simple structure, low manufacturing cost, and is convenient to manufacture and popularize.

Figure 2 is a schematic front view of the fixed bracket shown in Figure 1;

The marks in the above-mentioned figures are: 1. fixed bracket 2. fixed pulley; 3. movable pulley; 4. stay rope; 5. equipment; 6. utility pole.

Detailed ways

Referring to Figures 1 and 2, it can be seen that the lifting device of the power supply facility mainly includes: a fixed bracket 1 and a pulley block, the fixed bracket 1 is composed of two right-angled triangle brackets and a fixing rod connecting the two brackets, forming a three-dimensional right-angled triangle fixed bracket 1, One right-angle side of the fixed bracket 1 is provided with a detachable fixed ring, the fixed ring can be an annular snare with a specific opening, and the opening is fastened with bolts, and the fixed bracket 1 is fixed to the utility pole that needs to be hoisted through the fixed ring Top 6, the acute angle end of its other side right-angled side is provided with block pulley mounting shaft.

The pulley block includes a fixed pulley 2, a movable pulley 3 and a stay rope 4, wherein the fixed pulley 2 is fixed on the pulley block installation shaft of the fixed bracket 1, and the movable pulley 3 is provided with a hook for lifting equipment 5, and one of the stay rope 4 The rope end is fixed on the fixed pulley 2, after it surrounds the movable pulley 3 and the fixed pulley 2 successively, it extends to the ground by the pulley side of the fixed pulley 2, and the construction personnel can pull the stay rope 4 rope ends extending to the ground to carry out lifting work. In order to carry out live work, the fixed bracket 1 and the pulley block of the lifting device are all made of insulating materials.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model.
