Description

Lifting device for live installation of equipment on pole of power supply line

technical field

The utility model relates to a hoisting device, in particular to a hoisting device for being installed on a power supply line installation column.

Background technique

The equipment on the installation column of the power supply line (such as circuit breakers, etc.) needs to be replaced after a period of use, and usually requires replacement under live work. At present, when replacing the equipment on the pole of the power supply line, the following two methods are usually adopted: 1. Use the cross arm of the wire as the fulcrum, and hang the equipment on the pole by hanging the insulating pulley block on the cross arm; 2. Use a crane, etc. The aerial work equipment lifts the equipment on the column. The existing above two methods have the following disadvantages: for the former, the cross-arm is often bent and tilted due to excessive force, and in serious cases, the normal operation of the line is affected; for the latter, not only the cost is high, but also the equipment and personnel A safe distance cannot be guaranteed. In addition, when the above two methods are used, it is often impossible to carry out live work due to terrain and environmental restrictions.

Utility model content

The purpose of this utility model is to provide a lifting device for live installation of equipment on the power supply line column. The lifting device is installed on the power supply line installation column. The equipment on the column is lifted.

In order to achieve the above purpose, the utility model adopts the following scheme: the equipment on the power supply line column is charged with a lifting device, which has a pair of clamps that cooperate with each other, and the two clamps are connected by bolts and nuts, and one clamp is fixed with The support frame, the rear end of a swing arm is hinged with the support frame, the swing arm is connected with a telescopic arm, and a suspension ring assembly slidingly matched with it is installed on the telescopic arm.

It can be seen from the above scheme that a pair of hoops are attached to the installation column of the power supply line, and after the installation and fixing of the lifting device for this installation is completed, the insulated manual lifting device is hung on the ring assembly, and the manual lifting device can be used. The equipment on the column is lifted.

The utility model has a simple and reasonable structure and is convenient to use. It can greatly improve the operation efficiency when the equipment on the pole of the power supply line is replaced, and provide guarantee for live work.

Detailed ways

Below in conjunction with embodiment and accompanying drawing further illustrate the utility model.

See Figure 1, Figure 2

The live installation and lifting device of the equipment on the power supply line column has a pair of clamps 1 that cooperate with each other. The rear end of 6 is hinged with support frame 4, and swing arm 6 is connected with a telescopic arm 8, and the suspension ring assembly 9 that slides with it is installed on telescopic arm 8.

The rear end of the swing arm 6 has a pin hole 6b, and the support frame 4 is provided with three positioning holes 4a corresponding to the pin hole 6b. The centers of the three positioning holes 4a are on the same radius. 4a are aligned, and the positioning pin 5 is inserted in the plug hole 6b and the positioning hole 4a which are aligned with each other. According to the needs of the work, the positioning pin 5 is removed in the state shown in Figure 1 and Figure 2, and then the swing arm 6 is rotated so that the pin hole 6b on it is aligned with the other positioning hole 4a, and then the positioning pin 5 is inserted. , it can ensure that the swing arm 6 is positioned again after rotating an angle.

The swing arm 6 is hollow tubular. The swing arm 6 is provided with two rows of through holes 6a. The telescopic arm 8 is correspondingly provided with two latch holes 8a. The telescopic arm 8 extends into the swing arm 6. The two latches on the telescopic arm 8 The holes 8a are aligned with the two through holes 6a on the swing arm 6, and the fixed pins 7 are inserted in the pin holes 8a aligned with each other and the through holes 6a. Through the cooperation of the two pin holes 8a and the two rows of through holes 6a, the depth at which the telescopic arm 8 extends into the swing arm 6 can be adjusted.

See Figure 1, Figure 2, Figure 3

The suspension ring assembly 9 has a pair of support plates 9a, a suspension ring 9e and a pulley 9f, a pair of support plates 9a are connected with a support rod 9b and a wheel shaft 9d, and the pulley 9f and the suspension ring 9e are installed on the wheel shaft 9d. The inner side of the plate 9a is provided with a roller 9c, and the two sides of the telescopic arm 8 have a recessed slideway 8b, and the two rollers 9c are respectively in a slideway 8b and are supported by the bottom edge of the slideway. Through the cooperation of the roller 9c and the slideway 8b, the sliding cooperation between the suspension ring assembly 9 and the telescopic arm 8 can be realized. In addition, a limit block 10 is provided at the front end of the slideway 8b to prevent the suspension ring assembly 9 from falling off during use.

Combined with Figure 1, Figure 2 and Figure 3, it can be seen that a pair of hoops 1 are hooped on the power supply line installation column, and after the installation and fixing of the lifting device for this installation is completed, the insulated manual lifting device (such as a manual hoist) is hung on the lifting ring On 9e, the equipment on the column can be lifted by the manual lifting device. During the lifting process, the swing arm 6 rotates relative to the support frame 4 and the ring assembly 9 slides on the telescopic arm 8, which can be easily moved in the air. The equipment, and then successfully complete the lifting of the equipment. In addition, the pulley 9f on the ring assembly 9 can be used as a supporting point of the lifting device installed in this installation, and is used for hoisting work tools and the like during operation.

In addition, referring to Fig. 4, in order to adapt the installation and lifting device to installation columns of different diameters, it can be equipped with several semicircular hoop pads 11 with different diameters. The outer diameter of the hoop pad is the same as the inner diameter of the clamp. According to the need, fill the clamp pad between the clamp and the mounting column to ensure the reliable clamping of the clamp and the mounting column.
