Abstract
Description
Technical Field
[0001] This invention relates to the field of cable fixing technology, and in particular to a cable fixing assembly and an anti-loosening device. Background Technology
[0002] A cable is made of one or more insulated conductors and an outer insulating protective layer. Its function is to transmit electricity or information from one place to another. There are many types of cables. Power cables are used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. Cable laying methods commonly include direct burial, cable trench laying, cable tunnel laying, and wall laying. At the same time, overhead laying is also widely used in power distribution networks.
[0003] The common method is to install steel strands between poles or other sturdy structures, and then bind the power cable to the steel strands using BV wire, copper wire, aluminum wire, etc. However, this method of fixing power cables is not effective in securing the cables. In windy weather, the cables are prone to swaying, which will inevitably cause damage to the cables over time. In reality, it is common for cables to fall off or slip shortly after operation. This increases the difficulty of later operation and maintenance and affects the safe and stable operation of the cables. Therefore, we propose a cable anti-loosening roller frame locking device.

[0031] Example 1
[0032] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a cable fixing assembly, including a clamping plate 100, a cable hanging plate 301, and a locking plate 303; the clamping plate 100 is used to install the cable hanging plate 301, and the cable hanging plate 301 is used to install and adjust the height of the locking plate 303.
[0033] Specifically, there are two clamping plates 100, which are arranged facing each other.
[0034] Preferably, the cable hanger 301 and the locking plate 303 are disposed between the two clamping plates 100. The cable hanger 301 and the locking plate 303 are detachably connected, and the height of the locking plate 303 relative to the cable hanger 301 is adjustable. One end of the elastic membrane 302 is fixed to the bottom of the cable hanger 301 by adhesive bonding or tape binding, and the other end of the elastic membrane 302 is fixedly connected to the bottom of the locking plate 303 by adhesive bonding or tape binding.
[0035] Preferably, an accommodating space M is formed between the elastic membrane 302, the cable hanger 301, and the locking plate 303. The accommodating space M is used to store the cable. When the height of the locking plate 303 relative to the cable hanger 301 is adjusted, the accommodating space M will become larger or smaller. When the locking plate 303 rises relative to the cable hanger 301, the accommodating space M will become smaller, and the cable will be tightened by the elastic membrane 302.
[0036] Preferably, the elastic membrane 302 in this embodiment is made of rubber, which can absorb impact and vibration, thus facilitating the stability of the cable.
[0037] Example 2
[0038] This is the second embodiment of the present invention, which is basically the same as the first embodiment, except that the elastic membrane 302 in this embodiment is made of polyurethane, which has good wear resistance and elasticity, and facilitates the stability of the cable.
[0039] Example 3
[0040] See Figures 1-6 This is the third embodiment of the present invention, which is based on embodiment 1 or embodiment 2.
[0041] Preferably, the cable hanger 301 and the locking plate 303 are arranged parallel to each other. A limiting groove 301a is formed on the side of the cable hanger 301 facing the locking plate 303, and a locking hole is provided on the side of the locking plate 303 facing the cable hanger 301. The locking hole communicates with the limiting groove 301a and can move along the length of the limiting groove 301a. When the locking plate 303 and the cable hanger 301 move relative to each other in height, the locking hole moves along the length of the limiting groove 301a during this process.
[0042] Preferably, the locking plate 303 has a second bolt 303a in the locking hole, the second bolt 303a passes through the limiting groove 301a, and the cable hanging plate 301 has a second nut 303b on the side away from the locking plate 303; the locking plate 303 and the cable hanging plate 301 are connected by the second bolt 303a and the second nut 303b.
[0043] Example 4
[0044] See Figures 1-6 This is the fourth embodiment of the present invention, which provides an anti-loosening device.
[0045] Specifically, the two clamping plates 100 are connected on both sides of the middle section by a first bolt 101 and a first nut 101a respectively. The upper and lower parts of the opposite end faces of the two clamping plates 100 are respectively provided with a first arc-shaped locking groove 102 and a second arc-shaped locking groove 103. The inner wall of the second arc-shaped locking groove 103 is provided with a first limiting groove 103a. The two first arc-shaped locking grooves 102 are provided with steel strands 400.
[0046] A crossbar 500 is provided in each of the two second arc-shaped snap-fit grooves 103. Limiting strips 501 located in the first limiting groove 103a are respectively provided on the two side walls of the crossbar 500. The two ends of the crossbar 500 extend out of the second arc-shaped snap-fit grooves 103 and are respectively connected to fixing rods 502. The cable fixing mechanism 300 includes a cable hanging plate 301 disposed between the two fixing rods 502. An elastic rubber membrane 302 is glued to the bottom of one side of the cable hanging plate 301. The other end of the elastic rubber membrane 302 is glued to the bottom of the locking plate 303. The locking plate 303 and the two sides of the cable hanging plate 301 are respectively connected by a second bolt 303a and a second nut 303b. The upper part of the two clamping plates 100 is horizontally provided with a long strip first through groove 104 and vertically provided with a long strip second through groove 105, and the first through groove 104 and the second through groove 105 are connected.
[0047] The locking mechanism 200 includes a roller 201 disposed between two clamping plates 100. Each side of the roller 201 is provided with a first threaded rod 201a passing through the second through groove 105. The outer walls of the two first threaded rods 201a are threadedly connected with a third nut 201b.
[0048] The steel strand 400 and the crossbar 500 are respectively placed in the first arc-shaped locking groove 102 and the second arc-shaped locking groove 103 of the two clamping plates 100. The first bolt 101 and the first nut 101a are tightened to fix the position between the two clamping plates 100. Since the two side walls of the crossbar 500 are respectively provided with limiting strips 501 located in the first limiting groove 103a, the crossbar 500 will not rotate in the second arc-shaped locking groove 103, which reduces the sway amplitude of the cable hanging plate 301 when subjected to crosswinds and improves the stability of the cable.
[0049] The cable is placed under the cable hanger 301. The elastic rubber membrane 302 wraps around the cable and tightens it. Then, the locking plate 303 is fixed to the cable hanger 301 by the second bolt 303a and the second nut 303b. The cable will not easily move or fall off under the tight wrapping of the elastic rubber membrane 302. The elastic rubber membrane 302 also provides a layer of protection for the cable to avoid damage.
[0050] Preferably, the inner wall of the first arc-shaped snap-fit groove 102 is provided with threaded protrusions.
[0051] The threaded protrusions on the inner wall of the first arc-shaped locking groove 102 can increase the friction between the first arc-shaped locking groove 102 and the steel strand 400, allowing the two clamps 100 to be better fixed on the steel strand 400.
[0052] Preferably, the cable hanger 301 has vertically formed limit grooves 301a on both sides, and the locking plate 303 has a locking hole at the position corresponding to the two limit grooves 301a. The second bolt 303a passes through the locking hole and is connected to the second nut 303b.
[0053] The cable is placed under the cable hanger 301. After the elastic rubber diaphragm 302 wraps around the cable and tightens it, the locking plate 303 is moved up. After the fixed position is determined, the second bolt 303a passes through the locking hole and is connected to the second nut 303b, so that the locking plate 303 and the cable hanger 301 will not move. It can be used for cables of different sizes. For cables of different sizes, it is only necessary to determine the positional relationship between the locking plate 303 and the cable hanger 301.
[0054] Preferably, the locking mechanism 200 further includes a locking block 202 and a pressing block 203 disposed between the two clamping plates 100. The locking block 202 has a second threaded rod 202a passing through the first through groove 104 on both sides. The second threaded rod 202a is threadedly connected to the fourth nut 202b. The pressing block 203 has a right-angled triangle cross-section. The short side end face of the pressing block 203 faces the locking block 202 and is provided with a bearing seat 203a. The locking block 202 has a threaded hole in the middle. One end of the third threaded rod 203b is fixed to the inner ring of the bearing seat 203a. The other end of the third threaded rod 203b is threadedly connected to the threaded hole in the middle of the locking block 202 and extends outward. The other end of the third threaded rod 203b is provided with a hexagonal nut.
[0055] A fourth nut 202b is screwed onto the outer wall of the second threaded rod 202a that passes through the first through groove 104, thereby fixing the positional relationship between the locking block 202 and the two clamping plates 100.
[0056] Preferably, one of the two clamping plates 100 is provided with a second limiting groove 106, and a limiting block 203c located in the second limiting groove 106 is provided on the side of the extrusion block 203.
[0057] Turn the hexagonal nut at one end of the third threaded rod 203b with a wrench. The third threaded rod 203b drives the pressing block 203 forward. After contacting the roller 201, the pressing block 203 continues to move forward. The inclined surface of the pressing block 203 continuously presses the roller 201, causing the roller 201 to move down and press against the steel strand 400. When the pressing block 203 can hardly move forward anymore, tighten the third nut 201b on the outer wall of the first threaded rod 201a that passes through the second through groove 105 on both sides of the roller 201. This fixes the positional relationship between the roller 201 and the two clamping plates 100 and firmly presses it above the steel strand 400, strengthening the firmness between the steel strand 400 and the two clamping plates 100.
[0058] Working principle: The steel strand 400 and the crossbar 500 are placed in the first arc-shaped locking groove 102 and the second arc-shaped locking groove 103 of the two clamping plates 100 respectively. The first bolt 101 and the first nut 101a are tightened to fix the position between the two clamping plates 100. Since the two side walls of the crossbar 500 are respectively provided with limiting strips 501 located in the first limiting groove 103a, the crossbar 500 will not rotate in the second arc-shaped locking groove 103, which reduces the sway amplitude of the cable hanging plate 301 when subjected to crosswinds and improves the stability of the cable.
[0059] A fourth nut 202b is screwed onto the outer wall of the second threaded rod 202a passing through the first through slot 104, fixing the positional relationship between the locking block 202 and the two clamping plates 100. The hexagonal nut at one end of the third threaded rod 203b is turned with a wrench, and the third threaded rod 203b drives the pressing block 203 forward. After contacting the roller 201, the pressing block 203 continues to move forward. The inclined surface of the pressing block 203 continuously presses the roller 201, causing the roller 201 to move down and press against the steel strand 400. When the pressing block 203 can hardly move forward anymore, the third nut 201b is screwed onto the outer wall of the first threaded rod 201a passing through the second through slot 105 on both sides of the roller 201, fixing the positional relationship between the roller 201 and the two clamping plates 100, and firmly pressing it above the steel strand 400, strengthening the firmness between the steel strand 400 and the two clamping plates 100.
[0060] The cable is placed under the cable hanger 301. After the elastic rubber diaphragm 302 wraps around the cable and tightens it, the locking plate 303 is moved up. After the fixed position is determined, the second bolt 303a passes through the locking hole and is connected to the second nut 303b, so that the locking plate 303 and the cable hanger 301 will not move. It can be used for cables of different sizes. For cables of different sizes, it is only necessary to determine the positional relationship between the locking plate 303 and the cable hanger 301.
