Description

Technical Field

[0001] This utility model relates to cable protection devices, and in particular to a cable dragging protection device for coal mining faces. Background Technology

[0002] In the process of coal mining, electrical equipment is required, and electrical equipment requires electrical energy. Therefore, cables need to be laid in the coal mine. When the cables are being dragged and laid, in order to avoid damage to the cables due to friction with the ground, the cables are put into drag chains for dragging.

[0003] To prevent large stones from entering the cable chain during use, baffles are fixed at the top and bottom of the cable chain. However, when it is necessary to inspect the cables, the baffles are fixed in place, making it inconvenient to open them to inspect the cables inside the cable chain. Utility Model Content

[0004] The main purpose of this utility model is to provide a cable dragging protection device for coal mining faces, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable dragging protection device for a coal mining face includes a first movable plate, a second movable plate, a pin shaft, a connecting plate, a first flap, and a second flap. There are two first movable plates and two second movable plates. A connecting plate is fixedly installed between the two first movable plates, above and below them. A first flap is movably installed between the two second movable plates, above and below one end. A second flap is movably installed between the two second movable plates, above and below the other end.

[0007] More preferably, the two first movable plates and the two connecting plates form a first protective frame, and the two second movable plates, the first flip plate and the second flip plate form a second protective frame, and there are several first and second protective frames.

[0008] More preferably, pin holes are provided on the surface of the second movable plate near both ends, and shaft grooves are provided on the opposite side surface of the two second movable plates above and below the pin holes.

[0009] More preferably, the distance between the two first movable plates is greater than the distance between the two second movable plates, and pin holes are also provided on the surface of the first movable plate near both ends, with the pin shaft passing through the pin holes of the first and second movable plates.

[0010] More preferably, the front surface of the first flap is provided with a slot, and the rear two sides of the first flap are fixedly installed with shafts.

[0011] More preferably, the front surface of the second flap is fixedly equipped with an insert plate, and the rear two sides of the second flap are also fixedly equipped with shafts. The upper surface of the second flap and near the front end are provided with a handle groove.

[0012] More preferably, the shaft is movably embedded in the shaft groove, the first flap and the second flap are movably installed between the two second movable plates via the shaft, and the insert plate is embedded in the slot.

[0013] Compared with the prior art, this utility model proposes a self-cleaning solar street light, which has the following beneficial effects:

[0014] In this invention, the cooperation of the first and second flaps allows for the inspection of the cables inside the cable chain. When it is necessary to inspect the cables, one places their hand in the handle groove and lifts the second flap upwards, causing the insert plate of the second flap to disengage from the slot of the first flap. This allows the first and second flaps to be flipped open, exposing their obstruction areas and thus revealing the cables inside the cable chain for inspection. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-4 As shown, a cable dragging protection device for a coal mining face includes a first movable plate 1, a second movable plate 3, a pin shaft 6, a connecting plate 2, a first flap 4, and a second flap 5. There are two first movable plates 1 and two second movable plates 3. A connecting plate 2 is fixedly installed between the two first movable plates 1 and above and below them. A first flap 4 is movably installed between the two second movable plates 3 and above and below one end. A second flap 5 is movably installed between the two second movable plates 3 and above and below the other end.

[0022] Furthermore, the two movable plates 1 and the two connecting plates 2 form a first protective frame, and the two movable plates 3, the first flip plate 4 and the second flip plate 5 form a second protective frame. There are several first and second protective frames. When the first flip plate 4 and the second flip plate 5 are flipped open, the cables inserted inside the first and second protective frames can be conveniently inspected.

[0023] Furthermore, pin holes 301 are provided on the surface of the second movable plate 3 near both ends, and shaft grooves 302 are provided on the opposite side surface of the two second movable plates 3 above and below the pin holes 301.
