Description
Technical Field

[0002] Because most coal mining equipment is located underground, during work, the cables of coal mining equipment often need to cross a certain distance to connect to the power supply network on the ground. During this process, the cables are easily damaged by repeated trampling due to the passing of workers, and the coal mining equipment needs to change its position according to the conditions of the coal seam, so the cables also need to have certain mobility to adapt to the movement of the equipment. In this process, the cables may have fatal bends due to improper operation. Fatal bends usually refer to the bending degree of the wire exceeding its tolerable limit, causing physical deformation of the metal material inside the wire, and may even cause the wire to crack or the insulation layer to break. Therefore, it is necessary to protect it to prevent cable damage from causing equipment shutdown or even damage. Damaged cables may leak electricity, posing a hidden danger to the safety of workers.

When the equipment is moved, it is very easy to cause fatal bending of the cables. Most of the existing protective equipment is fixed and cannot be bent at a small angle. As a result, if you want to change the position of the equipment after installation or move the cables, you need to disassemble the entire device, which is very cumbersome.

Because the first rubber plate 34 and the second rubber plate 55 are made of rubber, they can have a certain deformation ability. When the upper fixed shell 3 and the lower fixed shell 4 are covered, the upper sleeve shell 51 and the lower sleeve shell 52 are also driven to cover. At this time, the first rubber plate 34 and the second rubber plate 55 will undergo a certain deformation, and then the surface of the wire body 2 is clamped and fixed. Even cables of different diameters can be clamped by deformation. After one protective component 1 is installed, the second protective component 1 is installed on the side close to the telescopic sleeve 5. During installation, open the upper fixed shell 3 and the lower fixed shell 4, and the installed The rotating plate 53 on the formed protective component 1 is placed into the interior of the first groove body 31, the wire body 2 is placed into the first card slot 37 and the second card slot 56, and then the upper fixed shell 3 and the lower fixed shell 4 are re-closed to complete the installation of the adjacent protective components 1.

The side wall of the second groove body 32 is provided with evenly distributed third groove bodies 33, and the outer surfaces of the ends of the upper sleeve shell 51 and the lower sleeve shell 52 away from the rotating plate 53 are fixedly installed with multiple evenly distributed first blocks 54, and the first blocks 54 are slidably clamped in the corresponding third groove bodies 33.
[0027] Because most coal mining equipment is located underground, during work, the cables of coal mining equipment often need to cross a certain distance to connect to the power supply network on the ground. During this process, the cables are easily damaged by repeated trampling due to the passing of workers, and the coal mining equipment needs to change its position according to the conditions of the coal seam, so the cables also need to have certain mobility to adapt to the movement of the equipment. In this process, the cables may have fatal bends due to improper operation. Fatal bends usually refer to the bending degree of the wire exceeding its tolerable limit, causing physical deformation of the metal material inside the wire, and may even cause the wire to crack or the insulation layer to break. Therefore, it is necessary to protect it to prevent cable damage from causing equipment shutdown or even damage. Damaged cables may leak electricity, posing a hidden danger to the safety of workers.
[0028] Traditionally, when protecting cables, most of them are fixed to the wall, or directly covered with plates, or directly covered with soil. However, the above methods do not provide complete protection for the cables, and the cables do not have a certain degree of mobility. When the equipment is moved, it is very easy to cause fatal bending of the cables. Most of the existing protective equipment is fixed and cannot be bent at a small angle. As a result, if you want to change the position of the equipment after installation or move the cables, you need to disassemble the entire device, which is very cumbersome.
[0029] Therefore, the present device is provided with a telescopic sleeve 5 and a first slot body 31. When the cable needs to be bent, the protective body will bend accordingly. When the protective body is bent, the rotating plate 53 rotates inside an adjacent first slot body 31. At this time, the upper sleeve shell 51 slides inside the second slot body 32, and the first clamping block 54 slides inside the third slot body 33 to adapt to the rotation between the two adjacent protective components 1. Since the width of the first slot body 31 is limited, the angle at which the rotating plate 53 can rotate inside the first slot body 31 is also limited. As a result, the present device can have the ability to rotate synchronously with the wire body 2 while preventing the wire body 2 from being fatally bent. Even if the coal mining equipment needs to be moved, there is no need to disassemble the device, and the device can automatically adapt to the bending of the cable.
[0030] Because the diameters of the first cylinder and the second cylinder are different from those of the wire body 2, when the wire body 2 and the protective body are bent at the same time, the inner walls of the wire body 2 and the protective body have different deformations. If the protective component 1 fixes the wire body 2 too much, the insulating layer of the wire body 2 will be damaged or even broken. Therefore, the device is provided with a plurality of first rubber plates 34 and second rubber plates 55. When the protective body and the wire body 2 are bent synchronously, the first rubber plate 34 can undergo axial deformation, thereby clamping the wire body 2 while reducing damage to the wire body 2.
[0031] The support seat component 6 includes a support seat plate 61, a first rotating kit 62 is fixedly installed on the upper surface of the support seat plate 61, a second rotating kit 63 is hinged on the upper surface of the first rotating kit 62, one end of the first rotating kit 62 and the second rotating kit 63 are detachably fixed by a mounting component 64, a plurality of evenly distributed clamping rods 36 are fixedly installed on one side of the upper fixed shell 3 close to the lower fixed shell 4, a plurality of mounting grooves 41 corresponding to the clamping rods 36 are opened on one side of the lower fixed shell 4 close to the upper fixed shell 3, second clamping blocks 57 are fixedly installed on both ends of the side of the rotating plate 53 close to the lower sleeve shell 52, and sealing grooves 58 corresponding to the second clamping blocks 57 are opened on both sides of the upper surface of the lower sleeve shell 52.
[0032] The mounting component 64 can be a structure such as a screw or a snap-on, and it only needs to be able to fix the first rotating kit 62 and the second rotating kit 63. During installation, when the upper fixed shell 3 and the lower fixed shell 4 are covered, the second rotating kit 63 is fixed to the first rotating kit 62, thereby establishing a reliable connection between the upper fixed shell 3 and the lower fixed shell 4. The clamping rod 36 and the mounting groove 41 cooperate to prevent the upper fixed shell 3 and the lower fixed shell 4 from being misaligned due to pressure. The second clamping block 57 and the sealing groove 58 can increase the connection tightness between the upper sleeve shell 51 and the lower sleeve shell 52, so that the upper sleeve shell 51 and the lower sleeve shell 52 can move synchronously to prevent misalignment and ensure stable operation of the device during use.
[0033] Working principle: When in use, first open the support seat component 6, then open the upper fixed shell 3 and the lower fixed shell 4, and then the upper sleeve shell 51 and the lower sleeve shell 52 are also driven to open, and the wire body 2 is placed inside the first card slot 37 and the second card slot 56, and then cover the upper fixed shell 3 and the lower fixed shell 4. Because the first rubber plate 34 and the second rubber plate 55 are made of rubber, they can have a certain deformation ability. When the upper fixed shell 3 and the lower fixed shell 4 are covered, the upper sleeve shell 51 and the lower sleeve shell 52 are also driven to cover. At this time, the first rubber plate 34 and the second rubber plate 55 will undergo a certain deformation, and then the surface of the wire body 2 is clamped and fixed. Even cables of different diameters can be clamped by deformation. After one protective component 1 is installed, the second protective component 1 is installed on the side close to the telescopic sleeve 5. During installation, open the upper fixed shell 3 and the lower fixed shell 4, and then The rotating plate 53 on the installed protective component 1 is placed into the interior of the first slot 31, and the wire body 2 is placed into the first card slot 37 and the second card slot 56, and then the upper fixed shell 3 and the lower fixed shell 4 are re-closed to complete the installation of the adjacent protective components 1. It is also possible to connect multiple protective components 1 in advance to form a protective body before installation, and then open the upper fixed shell 3 and the lower fixed shell 4 to place the wire body 2 into the interior of the protective component 1 to complete the installation. The upper fixed shell 3 and one end of the first slot 31 are both provided with a second slot 32, and the second cylinder is slidably clamped in the interior of the second slot 32. The side wall of the second slot 32 is provided with evenly distributed third slots 33, and the outer surfaces of the ends of the upper sleeve shell 51 and the lower sleeve shell 52 away from the rotating plate 53 are fixedly installed with a plurality of evenly distributed first clamping blocks 54, and the first clamping blocks 54 are slidably clamped in the corresponding third slots 33;
[0034] When the cable needs to be bent, the protective body will bend accordingly. When the protective body is bent, the rotating plate 53 rotates inside an adjacent first slot 31. At this time, the upper sleeve shell 51 slides inside the second slot 32, and the first clamping block 54 slides inside the third slot 33 to adapt to the rotation between the two adjacent protective components 1. Because the width of the first slot 31 is limited, the angle at which the rotating plate 53 can rotate inside the first slot 31 is also limited.
[0035] Because the diameters of the first cylinder and the second cylinder are different from those of the wire body 2, when the wire body 2 and the protective body are bent at the same time, the inner walls of the wire body 2 and the protective body have different deformations. If the protective component 1 fixes the wire body 2 too much, the insulating layer of the wire body 2 will be damaged or even broken. Therefore, the device is provided with a plurality of first rubber plates 34 and second rubber plates 55. When the protective body and the wire body 2 are bent synchronously, the first rubber plate 34 can be axially deformed, thereby clamping the wire body 2 and reducing damage to the wire body 2.
[0036] The mounting component 64 can be a structure such as a screw or a snap-on, and it only needs to be able to fix the first rotating kit 62 and the second rotating kit 63. During installation, when the upper fixed shell 3 and the lower fixed shell 4 are covered, the second rotating kit 63 is fixed to the first rotating kit 62, thereby establishing a reliable connection between the upper fixed shell 3 and the lower fixed shell 4. The clamping rod 36 and the mounting groove 41 cooperate to prevent the upper fixed shell 3 and the lower fixed shell 4 from being misaligned due to pressure. The second clamping block 57 and the sealing groove 58 can increase the connection tightness between the upper sleeve shell 51 and the lower sleeve shell 52, so that the upper sleeve shell 51 and the lower sleeve shell 52 can move synchronously to prevent misalignment and ensure stable operation of the device during use.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
