Description

Technical Field

[0001] The utility model relates to the technical field of ladder-type cable bridges, in particular to a variable-diameter positioning component of a ladder-type bridge for laying cables. Background Art

[0002] A ladder-type cable tray is a device used for laying cables. Its structure resembles a ladder, consisting of parallel horizontal beams and vertical supports. It allows cables to be laid along the horizontal beams, providing good ventilation and heat dissipation while facilitating installation and maintenance. Due to its open-hole design and durable material, ladder-type cable trays are suitable for a variety of environments and can support cables of different sizes, ensuring safety, orderliness, and reliability.

[0003] During the cable laying process, the cables are usually placed directly on the ladder-type bridge. However, due to the difference in cable diameter and unit mass, the cables can easily slip, causing friction between the cables or contact with the bridge, thereby damaging the cable insulation layer and seriously affecting the laying of the cables. Utility Model Content

[0004] The utility model aims to provide a variable diameter positioning component of a ladder-type bridge for cable laying, which can fix cables with different diameters.

[0005] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0006] A variable-diameter positioning assembly for a stepped cable tray for laying cables comprises two U-shaped side panels, with multiple horizontal panels disposed between them. Multiple threading rings are mounted on the upper surfaces of the horizontal panels, with multiple through-holes coaxially arranged on the surfaces of the threading rings. Guide rods are inserted into the through-holes, with a pressure block mounted on one end of the guide rods and a first wedge-shaped block mounted on the other end. Multiple circular rings are disposed on the outer sides of the horizontal panels, corresponding one-to-one with the threading rings. Multiple first connecting rods are mounted coaxially on the outer surfaces of the circular rings, with second wedge-shaped blocks mounted on the ends of the first connecting rods. A movable mechanism capable of driving the circular rings is disposed on the outer sides of the horizontal panels.

[0007] It can be seen that when the circular ring is driven to move toward the threading ring through the moving mechanism, the second wedge block and the first wedge block can be driven to squeeze each other, and then the pressure block is driven to move toward the center of the threading ring through the connection action of the guide rod. When the cable passes through the inside of the threading ring, multiple pressure blocks can be pressed against the outer surface of the cable at the same time to fix it, so that it can avoid sliding during the use of the cable and causing damage to the friction insulation layer. Moreover, multiple pressure blocks all move centripetally, so they are suitable for fixing cables of different diameters and have a wide range of applications.

[0008] Furthermore, the moving mechanism includes a screw rotatably mounted on the outer surface of the horizontal plate, a nut is mounted on the outer surface of the screw, a second connecting rod is connected to the outer surface of the nut, and the end of the second connecting rod is connected to the ring, and a knob is mounted on the end of the screw.

[0009] When the knob is turned to drive the screw to rotate, the nut can be moved along its length direction, and the connection function of the second connecting rod can achieve the purpose of driving the ring to move. By moving the ring toward the threading ring, the second wedge block can be driven to squeeze the first wedge block.

[0010] Furthermore, a spring is sleeved on the outer surface of the guide rod, and two ends of the spring are respectively in contact with the second wedge block and the circular ring.

[0011] When the first wedge block is squeezed and drives the pressure block to move toward the center of the threading ring, the first wedge block will compress the spring. When the ring drives the second wedge block away from the first wedge block, the compressed spring releases the elastic force, thereby pushing the pressure block away from the surface of the cable, making it easier to lay and adjust the cable.

[0012] Furthermore, a limit sliding groove is provided on the outer surface of the guide rod along its length direction, a limit sliding block is installed on the inner wall of the through hole, and the limit sliding block is arranged in the limit sliding groove.

[0013] By setting the limiting sliding groove and the limiting sliding block, the angle of the guide rod can be limited to prevent it from twisting and causing the pressure block to not fit the cable.

[0014] Furthermore, two slides are installed on the outer surface of the ring, and limiting rods are inserted into the interior of the slides, and the ends of the limiting rods are connected to the transverse plate.

[0015] The setting of the limiting rod and the slide plate can provide a limiting effect on the ring. When the screw rotates, the ring can move smoothly toward the threading ring, so that the second wedge block accurately corresponds to the first wedge block.

[0016] Furthermore, a connecting sleeve is installed at one end of the U-shaped side plate in the length direction, and a connecting block is installed at the other end of the U-shaped side plate in the length direction.

[0017] By arranging the connecting sleeve and the connecting block, the purpose of rapid splicing can be achieved when multiple sets of U-shaped side panels are spliced together, and the stability of the connection between two adjacent U-shaped side panels can be improved.

DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a variable diameter positioning assembly for a stepped cable tray for laying cables comprises two U-shaped side panels 100, with a plurality of transverse panels 101 disposed between the two U-shaped side panels 100. A plurality of threading rings 102 are mounted on the upper surface of the transverse panels 101, and a plurality of through holes 109 are coaxially arranged on the surface of the threading rings 102. A guide rod 103 is inserted into the through hole 109, and a pressure block 104 is mounted on one end of the guide rod 103, and a first wedge block 105 is mounted on the other end of the guide rod 103. A plurality of circular rings 106 are disposed on the outer side of the transverse panels 101, and the plurality of circular rings 106 correspond one-to-one to the plurality of threading rings 102. A plurality of first connecting rods 107 are coaxially arranged on the outer surface of the circular rings 106, and a second wedge block 108 is mounted on the end of the first connecting rod 107. A moving mechanism 200 capable of driving the circular rings 106 is disposed on the outer side of the transverse panels 101.

[0026] When in use, the cable is first passed through the inside of the threading ring 102 and the circular ring 106, and then the circular ring 106 is driven to move toward the threading ring 102 by the moving mechanism 200. The circular ring 106 drives the second wedge block 108 to squeeze the first wedge block 105. The first wedge block 105 is squeezed and shrinks toward the center of the threading ring 102. The connecting action of the guide rod 103 drives the pressing block 104 to press tightly on the outer surface of the cable. The joint compression of multiple pressing blocks 104 can achieve the purpose of quickly fixing the cable, and can prevent the cable from sliding during use and causing The friction insulation layer is damaged, and multiple pressure blocks 104 all move centripetally, so it is suitable for fixing cables of different diameters and has a wide range of applications. It is worth noting that the settings of the horizontal plate 101 and the threading ring 102 can be reasonably designed according to actual conditions. The number of pressure blocks 104 and the second wedge blocks 108 can be 6, 7, 8, etc. The more the number, the more force points the cable has, and the better the fixing effect. In addition, a rubber pad can be set on the surface of the pressure block 104 to further increase the friction between the cable and the cable, thereby improving the fixing effect, reducing the damage to the cable surface, and improving the protection effect.

[0027] Specifically, the moving mechanism 200 includes a screw 201 rotatably mounted on the outer surface of the horizontal plate 101, a nut 202 is mounted on the outer surface of the screw 201, a second connecting rod 203 is connected to the outer surface of the nut 202, and the end of the second connecting rod 203 is connected to the ring 106, and a knob 204 is mounted on the end of the screw 201. When the knob 204 is turned to drive the screw 201 to rotate, the nut 202 can be moved along its length direction, and the connection action of the second connecting rod 203 can achieve the purpose of driving the ring 106 to move. By moving the ring 106 toward the threading ring 102, the second wedge block 108 can be driven to squeeze the first wedge block 105.

[0028] Specifically, a spring 300 is sleeved on the outer surface of the guide rod 103, and the two ends of the spring 300 are respectively in contact with the second wedge block 108 and the ring 106. When the first wedge block 105 is squeezed and drives the pressure block 104 to move toward the center of the threading ring 102, the first wedge block 105 will compress the spring 300. When the ring 106 drives the second wedge block 108 away from the first wedge block 105, the compressed spring 300 releases the elastic force, thereby pushing the pressure block 104 away from the surface of the cable, which is convenient for laying and adjusting the cable.

[0029] Specifically, a limiting groove 400 is provided on the outer surface of the guide rod 103 along its length direction, and a limiting slider 401 is installed on the inner wall of the through hole 109. The limiting slider 401 is arranged in the limiting groove 400. By setting the limiting groove 400 and the limiting slider 401, the angle of the guide rod 103 can be limited to prevent it from twisting and causing the pressure block 104 to not fit the cable.

[0030] Specifically, two slides 501 are installed on the outer surface of the ring 106, and a limiting rod 500 is inserted into the interior of the slide 501. The end of the limiting rod 500 is connected to the cross plate 101. Through the setting of the limiting rod 500 and the slide 501, a limiting effect can be provided to the ring 106. When the screw 201 rotates, the ring 106 can be moved smoothly toward the threading ring 102, so that the second wedge block 108 accurately corresponds to the first wedge block 105.

[0031] Specifically, a connecting sleeve 600 is installed at one end of the U-shaped side panel 100 in the length direction, and a connecting block 601 is installed at the other end of the U-shaped side panel 100 in the length direction. Through the arrangement of the connecting sleeve 600 and the connecting block 601, when multiple groups of U-shaped side panels 100 are spliced and used, the purpose of quick splicing can be achieved, thereby improving the stability of the connection between two adjacent U-shaped side panels 100.

[0032] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, any equivalent substitutions or obvious modifications that do not depart from the concept of the present invention and have the same performance or use should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
