Description

Technical Field

[0001] The utility model belongs to the technical field of cable brackets, in particular to a non-horizontal section cable clamp for tunnels. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information and achieve conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables. When cables are laid in cable trenches, they are generally fixed with brackets. Commonly used brackets include angle steel brackets and assembled brackets, collectively referred to as cable brackets.

[0003] At present, in the process of using the cable bracket, the existing cable bracket has a simple structure and is not convenient for fixing the cable, which causes the cable to slip easily, is not convenient for use, and has low stability; and the structure of the existing cable bracket is fixed, and in the sloped cable trench, it cannot be well applied to the slope, and is not convenient for adjusting the angle, which causes the cable to be easily bent and damaged, reducing the efficiency of the cable bracket. At the same time, the lower end of the existing cable bracket is fixed, and cannot be retracted and folded, which is not convenient for transfer and installation. Utility Model Content

[0004] In view of this, the utility model aims to provide a non-horizontal section cable clamp for tunnels to solve the problem that the existing cable bracket cannot be used on slopes and the cable is easy to slip off.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A non-horizontal cable clamp for a tunnel comprises a support assembly, a platform, a rotating assembly, a clamping assembly, and a level meter. The support assembly, the platform, the rotating assembly, and the clamping assembly are arranged in sequence from bottom to top, and the level meter is arranged on the platform;

[0007] The top of the support assembly is hingedly arranged at the bottom of the platform, the bottom of the rotating assembly is arranged at the top center of the platform, and the top of the rotating assembly is connected to the bottom center of the clamping assembly.

[0008] Furthermore, the support assembly includes at least three telescopic assemblies evenly distributed in the circumferential direction and mounting plates corresponding to the number of telescopic assemblies, and the telescopic assemblies are hingedly arranged at the bottom of the platform through the mounting plates. The telescopic assemblies are hingedly arranged at the bottom of the platform, and the hinged arrangement can adjust the placement angle of the bracket, and can be applied to slopes with different inclination angles. When the cable bracket is transferred, the telescopic assembly can be retracted and folded by hinges, which is convenient for transportation and transfer.

[0009] Preferably, there are three telescopic components fixed on brackets in the tunnel. Many brackets cannot achieve planar support in a certain area due to application environment limitations. The telescopic components can be fixed on inclined surfaces to meet the needs of cable fixation in different situations.

[0010] Furthermore, the telescopic assembly includes a sleeve, a screw rod, and a plug rod. The sleeve is provided with an internal thread, and the outer side of the screw rod is provided with an external thread corresponding to the internal thread. The screw rod is screwed into the sleeve, and the end of the sleeve away from the screw rod is hingedly set at the bottom of the platform through a mounting plate, and the plug rod is set at the end of the screw away from the sleeve. The sleeve and the screw rod are screwed together to realize the telescopic assembly, so that it can further adapt to slopes with different inclination angles, and the height of the cable bracket can also be adjusted; after placing the cable bracket in a suitable position and adjusting the support assembly according to the inclination angle of the slope, the plug rod is inserted into the slope, which can fix the cable bracket and prevent the cable bracket from tipping over on the slope.

[0011] Furthermore, the level is arranged on the top of the platform. The level can be used to level the cable support or to monitor the cable support to be adjusted to a set inclination angle.

[0012] The level is an electronic level, and the model of the electronic level is ISE-L050.

[0013] Furthermore, the rotating assembly includes a ball joint seat and a ball joint rod, wherein the bottom of the ball joint seat is arranged at the top center of the platform, and the ball joint rod is arranged in the ball joint seat. Since the cable may need to move along the slope and adjust the position, the ball joint connection can facilitate the movement of the cable at any angle.

[0014] Furthermore, the clamping assembly includes a placement plate and two sliding assemblies. The bottom center of the placement plate is connected to the top of the ball hinge rod, and the two sliding assemblies are arranged on both sides of the top of the placement plate.

[0015] Furthermore, the sliding assembly includes an arc plate, a slider, and a rubber pad. One side of the arc plate is fixedly connected to the top of the slider, and a threaded hole is provided on the slider. The rubber pad is arranged on the inner side of the arc plate to protect the cable and avoid damage to the cable during laying.

[0016] Preferably, the arc-shaped plate is made of aluminum alloy, which has the function of breaking magnetism and preventing circulating current.

[0017] Furthermore, two sides of the top of the placement plate are provided with slide grooves corresponding to the sliders, and the sliders are slidably arranged in the slide grooves. The cable is placed on the placement plate and between the two sliding components, and the sliders slide in the slide grooves, so that the arc plate slides on the placement plate, thereby clamping and fixing the cable and preventing the cable from slipping on the slope.

[0018] Compared with the prior art, the non-horizontal section cable clamp for tunnels described in the utility model has the following advantages:

[0019] (1) The support assembly of the utility model can adjust the placement angle of the bracket, and can be used for slopes with different inclination angles.

[0020] (2) The sleeve and the screw described in the utility model can be telescopic, so as to further adapt to slopes with different inclination angles, and the height of the cable bracket can also be adjusted, and the plug rod can fix the cable bracket;

[0021] (3) The rotating assembly of the utility model can adjust the clamping assembly to any angle, thereby adapting to the placement angle of the cable and avoiding bending and damage of the cable;

[0022] (4) The clamping assembly of the utility model slides on the placement plate through two arc-shaped plates, thereby clamping and fixing the cable, thereby avoiding the problem of the cable easily slipping due to the cable bracket being placed on a slope. BRIEF DESCRIPTION OF THE DRAWINGS
