[0001] The present application relates to the technical field of cable support, in particular to a cable support for tunnel cable trench. BACKGROUND

[0002] The tunnel is provided with a cable trench, and cables in the cable trench are laid on the cable support. The cable support comprises a stand column for fixed connection with the side wall of the cable trench and a support arm for supporting the cables.

[0003] During the laying of the cables, the cables need to be pulled on the support arm, and the cables are manually moved to the correct position. Since the weight of the cables is generally large, manual pulling is laborious, and in the process of pulling, a large sliding friction force is generated between the cables and the support arm, which may cause the abrasion of the cable sheath. Therefore, the present application designs a cable support for tunnel cable trench to solve the above problems. SUMMARY

[0014] The beneficial effects of the present application are as follows:

[0015] 1. When the device needs to lay cables, the cables are placed on the upper surface of the sponge wheel, the cables are transported by the plurality of sponge wheels, the sponge wheel is made of soft material and will not damage the surface of the cable during movement, and can reduce the abrasion caused by dragging, and the cooperation of the moving mechanism and the feeding mechanism can move the cable to a suitable position on the upper surface of the support arm, that is, to replace manual placement of the cable, to prevent the cable from being inaccurately placed on the upper surface of the support arm in the initial state, and to prevent the cable from affecting the placement of the remaining cables.

[0016] 2. The U-shaped bracket inside the anti-skid mechanism and the supporting shaft can take out the damaged sponge wheel from the inner wall of the U-shaped bracket for replacement, avoiding the outer surface of the sponge wheel from contacting the cable for a long time, and the cement debris and solid dust possibly existing on the surface of the cable from contacting the sponge wheel and causing abrasion, resulting in damage of the sponge wheel and further causing the problem that the sponge wheel cannot transport the cable.

[0017] 3. The scraping plate inside the collecting component can scrape the solid dust existing on the surface of the sponge wheel to the inner wall of the arc-shaped collecting plate below for collection during the rotation of the sponge wheel. Through the collection of the arc-shaped collecting plate and the shielding of the cable below, the falling solid dust can be prevented from directly adhering to the surface of the cable below, affecting the transportation of the cable below. The removal of the solid dust adhering to the surface of the sponge wheel by the scraping plate can avoid the problem that the solid dust adhering to the surface of the sponge wheel causes abrasion during the transportation of the cable.

[0018] 4. The rollers and the bent rod inside the pressure sensing component can continuously press the rollers through the inclined lower surface of the bracket supporting arm during movement, and further cooperate with the pressure sensor to sense the change of the pressure, so as to control the placement of the cable. When the pressure becomes larger and larger, it indicates that the bracket supporting arm is deeper, and multiple cables can be placed on the upper surface of the bracket supporting arm in sequence, avoiding the problem that manual placement is troublesome, and also avoiding the problem that the cable is not accurately placed on the bracket supporting arm, resulting in the need to re-place the cable.

[0019] 5. The device scrapes off the cement debris or other solid waste possibly existing on the lower surface of the bracket supporting arm through the scraper, avoiding the problem that the rollers shake up and down during movement due to the existence of the solid waste when the rollers roll along the lower surface of the bracket supporting arm, so that the pressure sensor cannot accurately measure the pressure, and the moving mechanism places the cable on the upper surface of the bracket supporting arm in advance.

DETAILED DESCRIPTION

[0029] The present application will be further described below in conjunction with the drawings and specific embodiments. The embodiments of the present application are given for illustration and description only, and are not intended to be exhaustive or to limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application for various embodiments with various modifications as are suited to the particular use contemplated.

[0030] Embodiment one, please refer to Figures 1-5 The present application provides a technical solution: a cable support for a tunnel cable trench, comprising a stand 1, the inner surface of the stand 1 is fixedly connected with a bracket support arm 2, the outer surface of the bracket support arm 2 is fixedly connected with a moving mechanism 3, the side of the moving mechanism 3 away from the bracket support arm 2 is fixedly connected with a feeding mechanism 4, and the upper surface of the moving mechanism 3 is fixedly connected with an anti-skid mechanism 5; the bracket support arm 2 serves to place cables, the moving mechanism 3 can replace manual operation to move the cables to a suitable position on the surface of the bracket support arm 2, the feeding mechanism 4 can place multiple cables in turn on the upper surface of the bracket support arm 2 according to requirements, and the anti-skid mechanism 5 can facilitate the sliding of the cables on its surface, reduce the friction during the dragging of the cables, and avoid the abrasion of the outer sheath of the cables. Since the surface of the stand 1 is fixed with multiple bracket support arms 2, and multiple bracket support arms 2 can simultaneously perform the dragging operation of the cables, the present application only describes the placement operation of the cables on one bracket support arm 2.

[0031] Firstly, when the cable needs to be laid, the cable is placed on the upper surface of the anti-skid mechanism 5, which can reduce the wear caused by dragging during the process of dragging the cable. After the cable is dragged, the cable is moved to the appropriate position above the support arm 2 by the cooperation of the moving mechanism 3 and the feeding mechanism 4, and then the cable is placed. The cable can be placed on the upper surface of the support arm 2 in the appropriate position instead of manually, which prevents the cable from being placed inaccurately on the upper surface of the support arm 2 and affects the subsequent placement of the cable. It also increases the trouble of laying the cable by manually adjusting the position of the cable.

[0032] The moving mechanism 3 comprises a sleeve block 31, the lower surface of the sleeve block 31 is provided with a sliding groove 32, the outer surface of the sleeve block 31 is fixedly connected with a sliding rail 33, the upper surface of the sliding rail 33 is slidably connected with a sliding table 34, the upper surface of the sliding table 34 is fixedly connected with a support frame 35, the inner wall of the support frame 35 is fixedly connected with a motor 36, and the output end of the motor 36 is fixedly connected with a rotating shaft 37. The inner surface of the sleeve block 31 is shaped to fit the outer surface of the support arm 2, which can be sleeved on the outer surface of the support arm 2 to provide support and fixation for the feeding mechanism 4 and the anti-skid mechanism 5. The sliding groove 32 facilitates the subsequent operation of the feeding mechanism 4, and the sliding table 34 can slide along the outer surface of the sliding rail 33 and drive the movement of the anti-skid mechanism 5, thereby moving the cable to the appropriate position.

[0033] The inner surface of the sleeve block 31 is fixedly connected with the outer surface of the support arm, and the outer surfaces of both ends of the rotating shaft 37 are rotatably connected with the inner wall of the support frame 35.

[0034] The anti-skid mechanism 5 comprises an anti-skid box 51, the inner wall of the anti-skid box 51 is fixedly connected with a U-shaped frame 52, the inner surface of the U-shaped frame 52 is slidably connected with a support shaft 53, the outer surface of the support shaft 53 is sleeved with a sponge wheel 54, and the outer surface of the sponge wheel 54 is slidably connected with a collecting component 55. The cable can be placed on the upper surface of the sponge wheel 54. Since the sponge wheel 54 is made of soft material, it reduces the wear on the cable during the process of dragging the cable. The U-shaped frame 52 limits the up and down movement of the support shaft 53, which provides a placement position when replacing the sponge wheel 54.

[0035] The inner surface of the anti-skid box 51 is fixedly connected with the outer surface of the rotating shaft 37, and the inner surface of the sponge wheel 54 is rotatably connected with the outer surface of the support shaft 53.

[0036] When the cable is placed on the upper surface of the sponge wheel 54, the cable will contact the multiple sponge wheels 54 below during the process of dragging and drive the rotation of the multiple sponge wheels 54. The sponge wheel 54 is made of soft material and will not cause damage to the surface of the cable during the movement of the cable. It can also provide buffering and shock absorption during the transportation of the cable.

[0037] Since the construction is in the inside of the tunnel cable trench, the surface of the cable can be attached with a certain amount of cement debris and solid dust, so that the cement debris and water stains on the surface of the cable can be attached to the outer surface of the sponge wheel 54 during the cable dragging process, thereby increasing the contact force between the cable and the sponge wheel 54, so that the moving resistance of the cable becomes larger, and the outer surface of the cable can be damaged, so that the solid dust attached to the surface of the sponge wheel 54 needs to be scraped off.

[0038] When the sponge wheel 54 is attached with more and more solid dust, the solid dust with high hardness can damage the sponge wheel 54 when contacting and rubbing with the sponge wheel 54, and the water stains can penetrate into the inside of the sponge wheel 54, causing the sponge wheel 54 to soften and deform, so that the sponge wheel 54 needs to be replaced after a certain degree of use. When the outer surface of the sponge wheel 54 does not contact the cable, the support shaft 53 and the sponge wheel 54 can be slid upward from the inner wall of the U-shaped frame 52, and the support shaft 53 and the sponge wheel 54 can be taken out, so that a new sponge wheel 54 can be replaced on the outer surface of the support shaft 53.

[0039] The collecting part 55 comprises a scraping plate 551, the bottom of the scraping plate 551 is fixedly connected with an arc-shaped collecting plate 552, the inner wall of the arc-shaped collecting plate 552 is fixedly connected with a connecting shaft 553, the inner wall of the arc-shaped collecting plate 552 is fixedly connected with a cylindrical magnetic block 554, and the side, away from the arc-shaped collecting plate 552, of the cylindrical magnetic block 554 is fixedly connected with a magnetic plate 555. The cement block debris or soil debris existing on the outer surface of the sponge wheel 54 can be scraped off by the scraping plate 551, and the scraping plate 551 is arranged in an inclined shape, so that the debris can fall into the inside of the arc-shaped collecting plate 552, the inner wall of the arc-shaped collecting plate 552 is arranged in an arc shape, so that part of the soil block or mud block debris can fall to the bottom of the inner wall of the arc-shaped collecting plate 552, and the debris can be collected and treated. The cylindrical magnetic block 554 and the magnetic plate 555 are mutually adsorbed, the arc-shaped collecting plate 552 can be attached to the inner wall of the protection box, and the falling dust can be collected, and the arc-shaped collecting plate 552 can be opened when the dust is collected to a certain degree.

[0040] The upper surface of the scraping plate 551 is slidably connected with the outer surface of the sponge wheel 54, the outer surface of the arc-shaped collecting plate 552 is slidably connected with the inner wall of the anti-skid box 51, both ends of the connecting shaft 553 are rotatably connected with the inner wall of the anti-skid box 51, and the side, away from the cylindrical magnetic block 554, of the magnetic plate 555 is fixedly connected with the inner wall of the protection box.

[0041] When the outer surface of the sponge wheel 54 is attached with a certain amount of solid dust, the sponge wheel 54 will be in contact with the scraping plate 551 below during rotation, and the scraping plate 551 can scrape the solid dust on the surface of the sponge wheel 54 during the rotation of the sponge wheel 54, and the scraped solid dust falls into the inner wall of the arc-shaped collecting plate 552 below for subsequent collection. Since the surface of the stand column 1 is fixed with a plurality of support arms 2, and the plurality of support arms 2 can simultaneously perform cable dragging operation, the collection of dust by the arc-shaped collecting plate 552 can avoid the attachment of the falling solid dust to the surface of the cable below, which affects the transportation of the cable below.

[0042] The arc-shaped collecting plate 552 is in contact with the inner wall of the anti-skid box 51 in the initial state, and forms a wrapping space with the anti-skid box 51. When there is enough dust on the surface of the arc-shaped collecting plate 552, the worker manually pulls the side of the arc-shaped collecting plate 552 close to the magnetic plate 555 to rotate the arc-shaped collecting plate 552 downward around the outer surface of the connecting shaft 553, so that the outer surface of the arc-shaped collecting plate 552 is separated from the anti-skid box 51. At this time, the cylindrical magnetic block 554 inside the arc-shaped collecting plate 552 is separated from the magnetic plate 555. A collecting bag is placed below the arc-shaped collecting plate 552, and the solid dust on the surface of the arc-shaped collecting plate 552 falls into the collecting bag below during the downward rotation of the arc-shaped collecting plate 552. Then the arc-shaped collecting plate 552 is rotated upward around the outer surface of the connecting shaft 553, until the cylindrical magnetic block 554 is again adsorbed with the magnetic plate 555 to fix the arc-shaped collecting plate 552.

[0043] Embodiment two, please refer to Figures 1-8 The application provides a technical solution: on the basis of embodiment one, the feeding mechanism 4 comprises a connecting plate 41, the bottom end of the connecting plate 41 is fixedly connected with a pressure sensing component 42, one side of the pressure sensing component 42 is fixedly connected with an arc-shaped box 43, the inner wall of the arc-shaped box 43 is fixedly connected with a spring belt 44, the inner wall of the arc-shaped box 43 is slidably connected with an extrusion plate 45, the outer surface of the extrusion plate 45 is fixedly connected with a scraper 46, both sides of the extrusion plate 45 are fixedly connected with a wheel shaft 47, and the outer surface of the wheel shaft 47 is rotatably connected with an extrusion wheel 48. The connecting plate 41 fixes the sliding table 34 and the pressure sensing component 42, the extrusion wheel 48 can contact the lower surface of the support arm 2 to roll and extrude the extrusion plate 45 in real time along with the inclined surface of the lower surface of the support arm 2, so that the extrusion plate 45 always maintains sliding contact with the lower surface of the support arm 2. The scraper 46 can scrape off the soil debris or dry cement blocks that may be attached to the lower surface of the support arm 2, so as to avoid the influence of the cement blocks or attached dust on the operation of the pressure sensing component 42. The upper surface of the scraper 46 is in sliding contact with the lower surface of the support arm 2, and the spring belt 44 has the same function as the spring, both of which have elasticity and reset function.

[0044] The pressure sensing component 42 comprises a roller 421, the inner wall of the roller 421 is fixedly connected with a bent rod 422, the outer wall of the bent rod 422 is slidably connected with a sleeve 423, the outer surface of the sleeve 423 is provided with a vertical groove 424, the inner wall of the sleeve 423 is fixedly connected with an extrusion belt 425, the outer surface of the bent rod 422 is fixedly connected with a T-shaped frame 426, the bottom of the T-shaped frame 426 is fixedly connected with an extrusion spring 427, and the bottom end of the extrusion spring 427 is fixedly connected with a pressure sensor 428. The roller 421 can also roll along the lower surface of the support arm 2 and extrude the bent rod 422, and the extrusion degree of the bent rod 422 changes at any time as the inclination of the lower surface of the support arm 2 changes. The extrusion belt 425 and the spring have the same function, that is, they have elasticity and reset function. The roller 421 is arranged directly below the anti-skid box 51.

[0045] The top end of the connecting plate 41 is fixedly connected with the outer surface of the sliding table 34, the top end of the spring belt 44 is fixedly connected with the bottom of the extrusion plate 45, the outer surface of the sleeve 423 is fixedly connected with the side of the connecting plate 41 away from the sliding table 34, the top of the extrusion belt 425 is fixedly connected with the bottom of the bent rod 422, the outer surface of the T-shaped frame 426 is slidably connected with the inner surface of the vertical groove 424, and the bottom of the pressure sensor 428 is fixedly connected with the upper surface of the arc-shaped box 43.

[0046] After the cable is dragged, the cable is still on the upper surface of the plurality of sponge wheels 54, and needs to be moved to a suitable position on the upper surface of the support arm 2 by the moving mechanism 3. At this time, the sliding table 34 moves along the outer surface of the sliding rail 33 to the side close to the sleeve block 31, and drives the movement of the support frame 35, the motor 36, the rotating shaft 37 and the anti-skid mechanism 5 in the process of movement, that is, the movement of the cable can be driven. At the same time, the sliding table 34 can also drive the movement of the pressure sensing component 42, the arc-shaped box 43, the extrusion wheel 48 and the scraper 46 in the process of movement by the connecting plate 41. The extrusion wheel 48 will first roll in contact with the lower surface of the support arm 2, and then the upper surface of the scraper 46 will slide in contact with the lower surface of the support arm 2. As the extrusion wheel 48 continues to rotate in close contact with the lower surface of the support arm 2, the lower surface of the support arm 2 is constantly inclined, so the support arm 2 will constantly extrude the extrusion wheel 48, so that the extrusion wheel 48 and the scraper 46 slide downward along the inner wall of the arc-shaped box 43 and extrude the spring belt 44 at the bottom. Therefore, the scraper 46 can adjust and change with the change of the position of the extrusion wheel 48, so that the upper surface of the scraper 46 always slides in contact with the lower surface of the support arm 2, so that the cement blocks or solid dust on the lower surface of the support arm 2 can be scraped off, so that the solid dust adhered to the lower surface of the support arm 2 does not affect the subsequent operation of the pressure sensing component 42. The pressure sensing component 42 can place the cable in the anti-skid box 51 to the upper surface of the support arm 2 according to the inclination of the lower surface of the support arm 2 in the process of movement.

[0047] In the process of moving, the roller 421 also rotates in close contact with the lower surface of the support arm 2, and the support arm 2 will extrude the roller 421 and the bent rod 422, so that the roller 421 and the bent rod 422 slide downward along the inner wall of the sleeve 423 and extrude the internal extrusion belt 425, and the bent rod 422 drives the movement of the T-shaped frame 426 in the process of moving downward, so that the T-shaped frame 426 extrudes the extrusion spring 427 and the lower pressure sensor 428, and as the inclination of the lower support arm 2 becomes larger and larger, the pressure sensed by the pressure sensor 428 will also become larger and larger, and when the pressure reaches a certain value, the motor 36 located above the pressure sensor 428 drives the rotation of the rotating shaft 37, and drives the anti-skid box 51 to rotate downward, so that the cable in the anti-skid box 51 can slide along the inner wall of the anti-skid box 51 and fall onto the upper surface of the lower support arm 2, that is, the first cable is placed to the deepest position on the upper surface of the support arm 2, and when the cable is placed, the motor 36 drives the rotating shaft 37 to rotate in the opposite direction, so that the anti-skid box 51 rotates to the initial position again, facilitating the placement of the subsequent cable. Therefore, when different sizes of pressure are measured by the pressure sensor 428, the second and third cables can be sequentially arranged and placed on the upper surface of the support arm 2, realizing the sequential placement of multiple cables and replacing manual placement, saving manpower.

[0048] The scraper 46 first scrapes off the cement debris or other solid waste that may exist on the lower surface of the support arm 2, so that the subsequent roller 421 does not shake during movement along the lower surface of the support arm 2 due to the presence of solid waste, so that the pressure sensor 428 does not measure the pressure accurately, and the moving mechanism 3 does not place the cable too early.

[0049] When the first cable is placed, the sliding table 34 resets along the outer surface of the sliding rail 33, which can reset the material placing mechanism 4 and the anti-skid mechanism 5, facilitating the placement of the next cable.

[0050] The specific working process of the present application is as follows:

[0051] Firstly, when the cable needs to be laid, the cable is placed on the upper surface of the sponge wheel 54, and the sponge wheel 54 is transported by the plurality of sponge wheels 54, and the sponge wheel 54 is soft and will not damage the surface of the cable during movement, which can reduce the wear caused by dragging, and the cooperation of the moving mechanism 3 and the material placing mechanism 4 can move the cable to the appropriate position on the upper surface of the support arm 2, that is, to replace the manual placement of the cable, so as to prevent the initial position of the cable on the upper surface of the support arm 2 from being inaccurate, thereby affecting the placement of the remaining cables.

[0052] Through the U-shaped frame 52 and support shaft 53 inside the anti-slip mechanism 5, the damaged sponge wheel 54 can be taken out from the inner wall of the U-shaped frame 52 for replacement, avoiding prolonged contact between the outer surface of the sponge wheel 54 and the cable. Cement debris and solid dust that may be present on the cable surface may come into contact with the sponge wheel 54 and cause friction, resulting in damage to the sponge wheel 54 and thus the problem that the sponge wheel 54 cannot transport the cable.

[0053] The scraper 551 inside the collecting component 55 scrapes solid dust from the surface of the sponge wheel 54 onto the inner wall of the arc-shaped collecting plate 552 below during the rotation of the sponge wheel 54. The arc-shaped collecting plate 552 collects the dust and shields the cable below, preventing falling solid dust from directly adhering to the cable surface and affecting its transport. The scraper 551 removes solid dust from the surface of the sponge wheel 54, preventing frictional damage to the cable during transport caused by solid dust adhering to the surface.

[0054] During movement, the roller 421 and the bent bar 422 inside the pressure-sensing component 42 can continuously apply pressure to the roller 421 through the inclined lower surface of the bracket arm 2. In conjunction with the pressure sensor 428 sensing the changes in pressure, the placement of the cable is controlled. When the pressure increases, it indicates that the cable has entered the interior of the bracket arm 2 more deeply. Multiple cables can be placed on the upper surface of the bracket arm 2 in sequence, avoiding the problem of cumbersome manual placement. It also avoids the problem of inaccurate placement of the cable on the bracket arm 2, which would require repositioning the cable.

[0055] Finally, the scraper 46 removes any cement debris or other solid waste that may be present on the lower surface of the support arm 2. This prevents the roller 421 from shaking during its movement as it rolls along the lower surface of the support arm 2 due to the presence of solid waste. This prevents the pressure sensor 428 from measuring the pressure inaccurately, which could cause the moving mechanism 3 to prematurely place the cable on the upper surface of the support arm 2.
