[0002] The LBG3-630 / 3.3 high-voltage cable connector underground in coal mines is a commonly used connection device for high-voltage cables of fully-mechanized mining equipment. Due to the large size of this high-voltage cable connector and the lack of consideration of a scientific plugging and unplugging method in the initial design, it requires the cooperation of 2-3 people to complete each plugging and unplugging operation. At the same time, due to the lack of a suitable plugging and unplugging tool, the tools used for smooth plugging and unplugging are diverse, including screwdrivers, pointed cones, pickaxes, and even hammers. Using these tools for plugging and unplugging causes varying degrees of damage to the high-voltage cable connector each time, reducing its service life at least and damaging its internal insulation components at worst.

[0003] Based on this, the existing technology needs to be further developed. Summary of the Utility Model

Detailed Embodiments

[0020] To enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings of the present utility model. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only with reference to the directions of the accompanying drawings. Therefore, the directional terms used are for illustration rather than limitation of the present invention.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] According to an embodiment of the present utility model, a plugging and unplugging device for a high-voltage cable connector is provided. Please refer to Figures 1 to 2 , including: a movable component 1, two of the movable components 1 are provided in parallel and at intervals, and each movable component 1 includes a guide rod 11 and a rolling member; a push rod 3, both ends of the push rod 3 are respectively connected to the two rolling members to drive the two rolling members to roll synchronously along the guide rod 11; a first snap ring 4, the first ends of the two guide rods 11 are respectively connected to both ends of the first snap ring 4; a second snap ring 5, the two rolling members are respectively connected to both ends of the second snap ring 5, so that the second snap ring 5 makes a reciprocating motion along the length direction of the guide rod 11 to adjust the distance between the first snap ring 4 and the second snap ring 5.

[0023] It should be noted that through the cooperation of the movable component 1 and the guide rod 11, the relative movement of the second snap ring 5 with respect to the first snap ring 4 is realized, thereby completing the plugging and unplugging actions of the high-voltage cable connector. One person can independently perform the plugging and unplugging of the high-voltage cable connector. The structure is compact, easy to use, reduces the labor intensity of the operators, and improves the work efficiency; in addition, there is no need for violent plugging and unplugging, which reduces the damage to the high-voltage cable connector during the plugging and unplugging actions, thereby improving the service life of the high-voltage cable connector and reducing the maintenance and replacement costs.

[0024] Specifically, when removing the high-voltage cable connector, the second end of the guide rod 11 is abutted against the mounting surface of the socket of the high-voltage cable connector, so that the second snap ring 5 is close to the side of the flange on the plug of the high-voltage cable connector close to the mounting surface. Push the push rod 3 to make the rolling member move in the direction close to the first snap ring 4, thereby driving the second snap ring 5 to approach the first snap ring 4, and then pulling out the plug from the socket to complete the removal; when installing the high-voltage cable connector, first insert a part of the plug into the socket, and then respectively clamp the first snap ring 4 and the second snap ring 5 on the sides of the flange of the plug and the flange of the socket that are far away from each other. Push the push rod 3 to make the rolling member move in the direction close to the first snap ring 4, thereby driving the second snap ring 5 to approach the first snap ring 4, and then completely insert the plug into the socket to complete the installation.

[0025] Specifically, a plurality of tooth grooves 111 are provided on the surface of the guide rod 11, the rolling member is a check ratchet 123, and the ratchet teeth of the check ratchet 123 are engaged with the tooth grooves 111.

[0026] Preferably, both ends of the push rod 3 are fixedly connected to the connecting plate 121 through the connecting rod 2 to increase the force arm and make the insertion and extraction of the high-voltage cable connector more labor-saving.

[0027] In the high-voltage cable connector insertion and extraction device of this embodiment, a driving pawl 124 and a torsion spring are rotatably connected to the push rod 3. The torsion spring heads on both sides of the torsion spring are located between the driving pawl 124 and the push rod 3 to limit the angle formed between the driving pawl 124 and the push rod 3. The driving pawl 124 has driving pawl teeth. Taking the forward rotation of the check ratchet 123 towards the direction close to the first snap ring 4 as positive rotation, the driving pawl teeth are abutted against the side surface of a certain ratchet tooth to push the push rod 3. The acting force of the torsion spring prevents the driving pawl teeth from disengaging from the check ratchet 123, thereby driving the check ratchet 123 to rotate.

[0028] It should be noted that the reverse rotation of the check ratchet 123 is towards the direction away from the first snap ring 4. When it is necessary to reverse the check ratchet 123 to increase the distance between the second snap ring 5 and the first snap ring 4, the push rod 3 is pressed downward in the direction away from the first snap ring to disengage the driving pawl teeth from the check ratchet 123. Then, the push rod 3 can be pulled to reverse the check ratchet 123, so that the second snap ring 5 moves in the direction away from the first snap ring 4.

[0029] In the high-voltage cable connector insertion and extraction device of this embodiment, a mounting seat 12 is sleeved on the guide rod 11, and the mounting seat 12 is slidably connected to the guide rod 11. A receiving cavity 122 for receiving the check ratchet 123 is provided on the mounting seat 12, and the check ratchet 123 is fixedly connected to the cavity wall of the receiving cavity 122 through a first rotating shaft 126. In short, the driving pawl 124 of the check ratchet 123 is connected to the push rod 3, and the check pawl 125 of the check ratchet 123 is connected to the mounting seat 12.

[0030] It should be noted that the mounting seat 12 is sleeved on the guide rod 11, and the mounting seat 12 cooperates with the guide rod 11 to further guide the movement of the check ratchet 123 and ensure that the check ratchet 123 can only make a reciprocating movement on the guide rod 11.

[0031] In the high-voltage cable connector insertion and extraction device of this embodiment, a third rotating shaft 128 is fixedly provided at one end of the mounting seat 12 away from the first snap ring 4, and a check pawl 125 is rotatably connected to the third rotating shaft 128 relatively. Specifically, the check pawl 125 has check pawl teeth.

[0032] It should be noted that the check pawl 125 is a check pawl. Taking the installation of a high-voltage cable connector as an example, in order to make the second snap ring 5 continuously approach the first snap ring 4, the push rod 3 needs to be reciprocated multiple times. However, the check ratchet 123 is prone to rotate during multiple reciprocating operations, resulting in low installation efficiency. Therefore, the check pawl 125 is designed. When the check ratchet 123 has a tendency to rotate, the teeth of the check pawl catch the check ratchet 123 to prevent the check ratchet 123 from rotating, so as to improve the installation and disassembly efficiency of the high-voltage cable connector.

[0033] In the high-voltage cable connector plugging and unplugging device of this embodiment, the push rod 3 is rotatably connected to the mounting seat 12 through the connecting plate 121, and a space for accommodating the driving pawl 124 is left inside the connecting plate 121. A second rotating shaft 127 is fixedly provided on the connecting plate 121. The check pawl 125 is rotatably connected to the second rotating shaft 127, and the torsion spring is sleeved on the second rotating shaft 127.

[0034] Preferably, a straight section is provided at one end of the guide rod 11 away from the first snap ring 4, and no tooth grooves are provided on the surface of the straight section to limit the movement range of the check ratchet 123. Specifically, when the check ratchet 123 rotates reversely, since the mounting seat 12 limits the vertical movement of the check ratchet 123, and no tooth grooves are provided on the surface of the straight section, the check ratchet 123 stops rotating reversely when it reaches the straight section, preventing the check ratchet 123 and the mounting seat 12 from falling off the guide rod 11.

[0035] In the high-voltage cable connector plugging and unplugging device of this embodiment, both the first snap ring 4 and the second snap ring 5 are arc-shaped structures. A part of the arc-shaped structure fits with the flanges on the plug and the socket to achieve the plugging and unplugging of the high-voltage cable connector, and it can adapt to high-voltage cable connectors of various sizes.

[0036] In the high-voltage cable connector plugging and unplugging device of this embodiment, both ends of the second snap ring 5 are fixedly connected to 2 mounting seats 12 respectively. Specifically, the second snap ring 5 is connected to the mounting seat 12 through fasteners, and once the mounting seat 12 or the second snap ring 5 is damaged, it can be replaced separately.

[0037] The above has made a detailed description of the present invention. The above description is only a preferred embodiment of the present invention, and it cannot limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
