Description

Technical Field

[0001] This utility model relates to the field of coal mine electromechanical equipment technology, and in particular to a cable protection device for coal mine electromechanical equipment. Background Technology

[0002] Existing cables for coal mine electromechanical equipment are widely distributed, long, and heavy. The cables connecting the equipment often need to sway or change angles, which can easily cause the cables to loosen or break at the joints, thereby reducing their service life and indirectly increasing project costs.

[0003] The existing patent CN217956587U describes a cable protection device for coal mine electromechanical equipment, which includes a connecting device and a buffer device. The connecting device includes a first connecting block, with multiple first mounting holes evenly distributed inside the first connecting block. Two symmetrical connecting plates are fixedly connected to one side wall of the first connecting block. Two symmetrical pressure plates are hinged to the side wall of one of the two connecting plates. A first housing is fixedly connected to the outer wall of each of the two pressure plates. Multiple first springs are fixedly connected to the inner wall of the first housing. Pressure blocks are fixedly connected to the bottom ends of the multiple first springs. The connecting device can clamp the cable, thereby greatly reducing the impact of cable swaying on the connection. Furthermore, the buffer device can reduce the amplitude of cable swaying. Therefore, this invention can maximize the service life of the cable.

[0004] During use, the cable sizes are inconsistent, and existing equipment uses springs to clamp the cables, which cannot adjust the clamping force according to the cable diameter, resulting in low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a cable protection device for coal mine electromechanical equipment, which solves the problem that existing equipment uses springs to clamp cables, and the clamping force cannot be adjusted according to the diameter of the cable, resulting in low practicality.

[0006] To achieve the above objectives, this utility model provides a cable protection device for coal mine electromechanical equipment, including a mounting base and a fixing assembly. The fixing assembly includes a mounting cylinder, a driving component, a pressing block, a spring component, a fixing block, and a protective cover. The mounting cylinder is fixedly connected to the mounting base and located on one side of the mounting base. The pressing block is slidably connected to the mounting cylinder and located on the side of the mounting cylinder away from the mounting base. The driving component is mounted on the mounting cylinder and drives the pressing block to move. The fixing block is connected to the pressing block through the spring component, which drives the fixing block to move. The protective cover is fixedly connected to the mounting cylinder and located on the side of the mounting cylinder away from the mounting base.

[0007] The driving component includes a sliding block, a driving block, and a driving element. The sliding block is slidably connected to the mounting cylinder and is located on the side of the mounting cylinder away from the mounting base. The driving block is fixedly connected to the sliding block and is located on the side of the sliding block away from the mounting cylinder, and abuts against the pressing block. The driving element is mounted on the mounting cylinder and drives the driving block to move.

[0008] The driving element includes a threaded rod and a rotating block. The threaded rod is rotatably connected to the mounting cylinder and is located on the side of the mounting cylinder closer to the driving block, and is connected to the driving block. The rotating block is fixedly connected to the threaded rod and is located on the side of the threaded rod away from the driving block.

[0009] The elastic component includes a fixed cylinder, an extension rod, and an elastic element.

[0021] This utility model provides a cable protection device for coal mine electromechanical equipment, including a mounting base 100 and a fixing assembly. The fixing assembly includes a mounting cylinder 101, a driving component, a pressing block 102, a spring component, a fixing block 103, and a protective cover 104. The driving component includes a sliding block 105, a driving block 106, and a driving element. The driving element includes a threaded rod 107 and a rotating block 108. The spring component includes a fixing cylinder 109, an extending rod 110, and a spring element. The spring element includes a connecting rod 111 and a spring 112. This solution solves the problem that existing equipment uses a spring 112 to clamp the cable, but the clamping force cannot be adjusted according to the cable diameter, resulting in low practicality.

[0022] In this specific embodiment, the mounting base 100 is the first connecting block described in the cable protection device for coal mine electromechanical equipment in the existing patent technology CN217956587U. The mounting base 100 is connected to the equipment. This solution enables the buffer device to adjust the clamping force of the spring 112 according to the size of the cable, thereby improving the practicality of the equipment.

[0023] The mounting cylinder 101 is fixedly connected to the mounting base 100 and located on one side of the mounting base 100. The lower pressure block 102 is slidably connected to the mounting cylinder 101 and located on the side of the mounting cylinder 101 away from the mounting base 100. The driving member is mounted on the mounting cylinder 101 and drives the lower pressure block 102 to move. The fixing block 103 is connected to the lower pressure block 102 through the elastic member, and the elastic member drives the fixing block 103 to move. The protective cover 104 is fixedly connected to the mounting cylinder 101 and located on the side of the mounting cylinder 101 away from the mounting base 100. The mounting cylinder 101 is bolted to the mounting base 100, allowing the mounting cylinder 101 to be stably mounted on the electromechanical equipment. The lower pressure block 102 is slidably mounted on the mounting cylinder 101. The mounting cylinder 101 has a groove that mates with the lower pressure block 102, thereby allowing the lower pressure block 102 to be stably mounted on the electromechanical equipment. The mounting cylinder 101 moves up and down. The driving component is mounted on the mounting cylinder 101 and controls the movement of the lower pressure block 102. The fixing block 103 and the protective cover 104 are the pressure block and first protective cover described in the prior art patent CN217956587U cable protection device for coal mine electromechanical equipment. The fixing block 103 has an anti-slip pad on one side. The fixing block 103 is mounted on the lower pressure block 102 by the elastic component, so that the fixing block 103 abuts against the cable and reduces the swaying amplitude of the cable by the elastic component. The driving component drives the lower pressure block 102 to move, thereby controlling the clamping of the cable by the fixing block 103. The protective cover 104 is mounted on the mounting cylinder 101 by bolts to protect the cable from being damaged by the mounting cylinder 101 when it sways. This allows the pressure block to adjust the clamping force of the spring 112 according to the size of the cable, thereby improving the practicality of the equipment.

[0024] Secondly, the sliding block 105 is slidably connected to the mounting cylinder 101 and is located on the side of the mounting cylinder 101 away from the mounting base 100; the driving block 106 is fixedly connected to the sliding block 105 and is located on the side of the sliding block 105 away from the mounting cylinder 101, and abuts against the pressing block 102; the driving element is mounted on the mounting cylinder 101, the driving element drives the driving block 106 to move, the sliding block 105 is slidably mounted on the mounting cylinder 101, and the mounting cylinder 101 has a groove that cooperates with the sliding block 105, so that the sliding block 105 can... The mounting cylinder 101 slides left and right. The driving block 106 is fixedly mounted on the sliding block 105 by bolts. The sliding block 105 enables the driving block 106 to slide stably on the mounting cylinder 101. Both the sliding block 105 and the pressing block 102 have inclined surfaces. The sliding block 105 moves left and right, thereby controlling the pressing block 102 to move up and down, which in turn drives the fixed block 103 to move. The driving element is mounted on the mounting cylinder 101. The driving element drives the driving block 106 to move, thereby controlling the pressing block 102 to move.

[0025] Meanwhile, the threaded rod 107 is rotatably connected to the mounting cylinder 101 and is located on the side of the mounting cylinder 101 close to the driving block 106, and is connected to the driving block 106; the rotating block 108 is fixedly connected to the threaded rod 107 and is located on the side of the threaded rod 107 away from the driving block 106. The threaded rod 107 is mounted on the mounting cylinder 101 by a bearing and passes through the driving block 106. The driving block has a threaded hole that mates with the threaded rod 107, so that the threaded rod 107 can drive the driving block 106 to move to the left and rear. The rotating block 108 is installed by welding at the end of the threaded rod 107 that extends out of the mounting cylinder 101, and the rotating block 108 enables more convenient rotation of the threaded rod 107.

[0026] Additionally, the fixed cylinder 109 is fixedly connected to the lower pressure block 102 and is located on the side of the lower pressure block 102 away from the driving block 106; the extending rod 110 is slidably connected to the fixed cylinder 109 and is located on the side of the fixed cylinder 109 away from the lower pressure block 102, and is connected to the fixed block 103; the elastic element is mounted on the fixed cylinder 109, and the elastic element drives the extending rod 110 to move; the fixed cylinder 109 is bolted to the lower pressure block 102, and the extending rod 110... The rod 110 is slidably mounted on the inner side of the fixed cylinder 109. The end of the extension rod 110 away from the fixed cylinder 109 is bolted to the fixed block 103. The fixed block 103 is supported by the cooperation of the fixed cylinder 109 and the extension rod 110. The elastic element is mounted on the inner side of the fixed cylinder 109. The elastic element drives the extension rod 110 to move, which in turn drives the fixed block 103 to move, so that the fixed block 103 abuts against the cable, thereby fixing the cable.

[0027] Finally, the connecting rod 111 is fixedly connected to the fixed cylinder 109 and is located on the side of the fixed cylinder 109 away from the extending rod 110, and is connected to the extending rod 110; the spring 112 is sleeved on the outside of the connecting rod 111, and the two ends of the spring 112 abut against the fixed cylinder 109 and the extending rod 110 respectively; the connecting rod 111 is fixedly connected to the fixed cylinder 109 and is located at the end of the fixed cylinder 109 away from the extending rod 110; the connecting rod 111... The other end is connected to the extension rod 110 by a bolt. The connecting rod 111 is a telescopic short rod. The connection prevents the extension rod 110 from slipping out of the fixed cylinder 109. The spring 112 is sleeved on the outside of the connecting rod 111, and the two ends of the spring 112 abut against the fixed cylinder 109 and the extension rod 110 respectively. The elastic force of the spring 112 drives the extension rod 110 to move, thereby enabling the fixed block 103 to abut against the cable and reduce the sway of the cable.

[0028] Using the cable protection device for coal mine electromechanical equipment in this embodiment, after the mounting cylinder 101 is installed on the electromechanical equipment via the mounting base 100, the cable passes through the mounting cylinder 101. At this time, the rotating block 108 is rotated, and the rotating block 108 drives the threaded rod 107 to rotate. The threaded rod 107 drives the driving block 106 to move to the left, thereby abutting against the lower pressure block 102. The lower pressure block 102 drives the fixed cylinder 109 and the extension rod 110 to move downward, thereby making the fixed block 103 abut against the cable. By continuously moving the lower pressure block 102, the fixed block 103 abuts against the cable more tightly, and the spring 112 is compressed, thereby fixing the cable. This allows the clamping force of the spring 112 to be adjusted according to the size of the cable, thereby improving the practicality of the equipment.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
