Description

Technical Field

[0001] The invention relates to the field of power distribution operation and inspection, and in particular to a frame-transformed telescopic insulating workbench. Background Art

[0002] A rack transformer usually refers to a transformer installed on a pole. It is a simple collective equipment distribution facility used to reduce medium voltage to low voltage. According to the search results, a rack transformer usually consists of a distribution transformer and switchgear, installed on one or more poles, and is suitable for a 10kV distribution system. A JP cabinet, or integrated distribution box, is a power equipment that integrates multiple functions, mainly used for the distribution, metering, protection, control, and reactive power compensation of electric energy18. It is suitable for a variety of occasions, such as urban power grids, rural power grid reconstruction, industrial and mining enterprises, street lighting, residential areas, etc., and can play a role in a distribution system with an AC 50Hz and a rated voltage of 380V.

[0003] Since the height of the bench-type JP cabinet is relatively high, maintenance operations must be performed with the aid of an insulating ladder. In the prior art, the insulating ladder is inconvenient to transport due to its large size, and is not conducive to the transportation of small vehicles such as two-wheeled electric vehicles. In addition, due to the limited placement of the insulating ladder, the insulating ladder has an insufficient inclination angle, and the staff cannot stand steadily on the ladder. In addition, the bench-type operation and maintenance work sometimes requires frequent alternation between the two sides of the JP, and the insulating ladder needs to move back and forth. It is restricted by the fence and is inconvenient to move, which makes it very easy for the operation and maintenance personnel to fall during work due to unstable standing and frequent ups and downs. Therefore, it is necessary to adopt a bench-type telescopic insulating workbench. Summary of the invention

The two sliding seats are connected by a connecting rod, and both ends of the connecting rod are rotatably connected to the sliding seats. The two connecting rods are cross-arranged, and the middle ends of the two connecting rods are rotatably connected, and the slide rail is fixedly connected to the unfolding frame.

[0012] Preferably, the insulating plate comprises a main plate rotatably connected to the side of the sliding sleeve 3 away from the sliding rail, and the front and rear sides of the main plate are both rotatably connected to auxiliary plates.

[0017] Preferably, the bottom side of the unfolding frame and the bottom side of the supporting frame are both equipped with universal wheels via wheel frames.

[0018] Working principle: When the telescopic insulating workbench is needed, the top shell and the connected storage structure inside the box are supported by the electric guide rail with the support frame as the base. During this period, the gear inside the shell and the rack on the support frame are meshed with each other, so that the gear rotates, and the two bevel gears connected to the gear transmission drive the rotating rod connected to the box door to rotate, so as to open the box doors on both sides, and pull the multiple telescopic brackets at the front end together, thereby pulling the structure including the sliding sleeve five connected to the rear end, so that the sliding sleeve five slides forward along the sliding rod under the traction of the structure connected to the front end. The two extension frames are displaced to the sides by pulling the two connecting rods, and the two connecting rods rotate, the angle changes, and the angle gradually widens. The sliding seat connected to the connecting rod on the extension frame slides and moves. Thereby, the telescopic bracket is unfolded, and then the box body is continuously lifted to reach the height of the platform. According to the height of the box body, each telescopic bracket can be slid on the sliding sleeve 1 through the sliding piece, so that the telescopic bracket falls down, forming a ladder shape from back to front, and the sliding sleeve 3 is vertically slid on the slide rail to adjust the height of the insulating board. When the displacement reaches a certain height, the support rod is taken out of the fixed groove, rotated, and the fixed groove 2 on the internal slide bar is pulled down through the opening of the fixed groove 1 to increase the overlap between the opening of the fixed groove 2 and the opening of the fixed groove 1. At this time, the bottom end of the support rod is buckled into the fixed groove 1 and the fixed groove In the second process, the downward displacement of the slider will cause the standing foot at its bottom to move downward, causing the spring connected to the top to stretch, thereby causing the front standing foot to stand on the ground for support. The slider is pulled by the spring to return, causing the slider to tend to move upward, thereby causing the second fixed groove on the slider to exert a squeezing force on the support rod. At this time, the first fixed groove and the second fixed groove are misaligned to clamp the support rod, so that the support rod supports the insulating board. The insulating boards on each telescopic bracket are finally arranged into a stepped structure for people to go up and down, and then the side panels on the main board are unfolded, thereby completing the unfolding and allowing staff to go up and down.

[0019] The present invention provides a telescopic insulating workbench with a frame, which has the following beneficial effects:

[0020] 1. The present invention can store the entire structure into the box through the storage structure, thereby reducing the space occupied, thereby achieving the purpose of being easy to carry, and can be transported by a small vehicle, solving the problem of inconvenient transportation.

[0021] 2. The present invention can reach the position of the bench by rising, and can open the box door synchronously, and the telescopic frame and insulating plate pulled out therefrom can be matched with the height to form a step shape, so as to adapt to benches of different heights, thereby improving the flexibility of the insulating workbench.

[0022] 3. The present invention solves the problem of unstable operation on the ladder by installing two telescopic insulating workbenches on the platform, and moves the insulating workbenches through lockable universal wheels, thereby making the movement more convenient. The universal wheels under the unfolding frame cooperate with the downward-moving standing feet to increase the friction of the unfolding frame standing on the ground, thereby improving stability.
