Description

Technical Field

[0001] This utility model relates to the field of ladder-type cable tray technology, and in particular to a ladder-type cable tray turning assembly with guide wheels. Background Technology

[0002] A ladder-type cable tray turning assembly with guide wheels refers to a rigid connection component specifically designed for ladder-type cable tray systems. It integrates a guide wheel mechanism to enable smooth transition of cables at turns. It is suitable for nodes in long-distance cable tray systems that require a change of direction, such as factories and tunnels. The guide wheels effectively solve the problem of difficulty in pulling thick and stiff cables at turns and are a key functional component in complex cabling projects.

[0003] Patent document CN219436542U discloses a cable tray structure for cable lead-up devices, including a cable hanger, a trough-type cable tray, and a ladder-type cable tray. The trough-type and ladder-type cable trays are fixedly installed within the inner cavity of the cable hanger. The device also includes a cable lead-up tray assembly, which is fixedly installed on the lower end face of the floor. This invention, through the installation of the cable lead-up tray assembly, facilitates the installation of the cable hanger and the subsequent maintenance of the cables within the trough-type and ladder-type cable trays.

[0004] However, existing ladder-type cable tray turning assemblies with guide wheels are difficult to adapt to the cable laying requirements of different diameter specifications, and the cables are prone to loosening or deviation, which cannot ensure balanced force at the turning point and increases the frictional resistance of the cable when turning.

[0015] (III) Beneficial Effects

[0016] This utility model provides a ladder-type cable tray turning assembly with guide wheels, which has the following advantages:

[0017] 1. This ladder-type cable tray turning assembly with guide wheels, by adjusting the assembly settings, allows the cable to pass between two sets of guide wheel bodies during use. Then, according to the cable diameter, the two sets of limit nuts are rotated to push the lifting seat to slide to a suitable height on the threaded rod surface. At the same time, the position of the top limit nut remains unchanged, and the limit nut at the bottom of the support spring is rotated to adjust the extension and contraction of the support spring. When the cable is pulled, the elastic force of the support spring is used to keep the guide wheel body in close contact with the cable surface, thereby achieving the effect of accommodating the cable installation requirements of different diameter specifications and maintaining stability, preventing the cable from loosening or shifting, ensuring balanced force at the turning point, and reducing the frictional resistance of the cable when turning.

[0018] 2. This ladder-type cable tray turning assembly with guide wheels, through the setting of limiting components and turntable, allows for the following operation: at the cable tray turning point, the sliding block moves to the appropriate position on the sliding rod, and then the limiting bolt is tightened for fixation. According to the required bending angle of the cable, the turntable is rotated, causing the turntable to drive the support base and the guide wheel body to deflect at an angle. The limiting rod slides in the groove on the turntable, and the limiting nut rotates on the limiting rod, pressing against the surface of the turntable for fixation and limitation. This allows the guide wheel to be precisely aligned with the central axis of the cable tray bending component, ensuring that the cable bending arc matches the cable tray structure and avoiding stress concentration or insulation damage to the cable due to sudden angle changes. It also adapts to the bending angle required by different cables. Attached Figure Description

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a ladder-type cable tray turning assembly with guide wheels, comprising several sets of turntables 1, with two sets of support seats 2 fixedly connected to the top of the turntables 1, and an adjustment assembly 3 fixedly connected to the top of the support seats 2. The adjustment assembly 3 is designed to accommodate cables of different diameters and maintain stability, preventing cable loosening or deviation, ensuring balanced force at the turning point, and reducing frictional resistance during cable turning. A lifting seat 4 is slidably connected to the surface of the adjustment assembly 3, and a base 5 is rotatably connected to the bottom of the turntables 1. A limit assembly 6 is fixedly connected to the top of the base 5. The adjustment assembly 6 and the turntables... The setting of disc 1 allows the guide wheel to be precisely aligned with the central axis of the cable tray bend component, ensuring that the cable bending arc matches the cable tray structure and avoiding stress concentration or insulation damage caused by sudden angle changes. It also adapts to the bending angle required by different cables. The adjustment component 3 includes a threaded rod 301 fixedly connected to the top of the support base 2. The surface of the threaded rod 301 is threaded with two sets of limit nuts 302, and the top surface of one set of limit nuts 302 is fixedly connected with a support spring 303. The limiting component 6 includes a limiting rod 601 fixedly connected to the top of the base 5. The top of the limiting rod 601 is threadedly connected with a limiting nut 602.

[0026] Both the support base 2 and the lifting base 4 are rotatably connected to one side of a guide wheel body 7. The guide wheel body 7 is made of rubber and serves to guide and support the cable.

[0027] Two sets of positioning rods 8 are fixedly connected to the top of the support base 2. The positioning rods 8 are slidably connected inside the lifting base 4. The positioning rods 8 play a role in maintaining the stability of the lifting base 4.

[0028] The limiting rod 601 is slidably connected to the inside of the turntable 1. The surface of the turntable 1 is provided with a sliding groove that matches the limiting rod 601. The sliding groove facilitates the sliding of the limiting rod 601 inside.

[0029] A sliding block 9 is fixedly connected to the bottom of the base 5. Sliding sleeves 10 are fixedly connected to both ends of the sliding block 9. The sliding sleeves 10 facilitate sliding on the surface of the sliding rod 11.

[0031] The sliding sleeve 10 has a threaded hole on its surface, and a limit bolt 14 passes through the inside of the threaded hole. The limit bolt 14 serves to limit the sliding sleeve 10.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When in use, pass the cable between the two sets of guide wheel bodies 7, and then rotate the two sets of limit nuts 302 according to the diameter of the cable to push the lifting seat 4 to slide on the surface of the threaded rod 301 to a suitable height. At the same time, the position of the top limit nut 302 remains unchanged. Rotate the limit nut 302 at the bottom of the support spring 303 to adjust the extension and retraction of the support spring 303. When the cable is pulled, the elastic force of the support spring 303 is used to keep the guide wheel body 7 in close contact with the cable surface.

[0034] The second step: When in use, at the bend of the cable tray, move the sliding block 9 to the appropriate position on the sliding rod 11, then tighten the limiting bolt 14 to fix it, and rotate the turntable 1 according to the angle that the cable needs to bend, so that the turntable 1 drives the support seat 2 and the guide wheel body 7 to deflect by an angle, and the limiting rod 601 slides in the groove on the turntable 1. The limiting nut 602 rotates on the limiting rod 601 and presses the surface of the turntable 1 to fix and limit it.
