Description

Technical Field

[0001] This utility model relates to the field of cable construction technology, specifically to a cable construction auxiliary device. Background Technology

[0002] Cable laying is a common and crucial part of power system construction and municipal engineering projects, involving the installation of power cables, communication optical cables, and other cables. With the continuous advancement of urban power grid upgrades and infrastructure construction, the scale of cable construction is expanding daily, and the construction environment is becoming increasingly complex, encompassing various scenarios such as underground utility tunnels, tunnels, and bridges.

[0003] According to CN120341760A, a cable laying device for power construction is disclosed. This technology discloses a technical solution including "a frame, with a motor fixedly installed on one side inside the frame, and two motors symmetrically arranged around the frame". It has the following technical effects: "When the cable passes between the two bends and moves along the rotation direction of the traction component, the operation of the motor, transmission device and other components will generate vibration during the operation of the equipment, which will be transmitted to the cable. The vibration generated by the cable will cause the cable to vibrate between the bends. When the cable vibrates, the connecting rings on both sides of the bend will displace on the surface of the outer shaft and squeeze the spring. The spring will contract under force to buffer the vibration frequency of the cable. During the laying process, the cable sheath will be worn or even the internal structure will be damaged, affecting the service life of the cable and the quality of power transmission".

[0004] In existing cable traction devices, when the spacing between the upper and lower traction components needs to be adjusted according to different cable diameters during construction, the traction operation must be interrupted to make the adjustment, resulting in low construction efficiency and cumbersome operation procedures. Since it is impossible to complete the spacing adjustment while maintaining continuous traction, the construction process is forced to be carried out in segments, which not only affects work efficiency but may also lead to uneven cable stress and increase construction risks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable construction auxiliary device, comprising a base, a traction mechanism mounted on the base for cable traction, and a moving mechanism mounted on the base for overall movement; the traction mechanism includes:

[0007] The main components include uprights fixed on both sides of the top of the base, a top plate fixed between the tops of the uprights, a shaft rotatably mounted between the top plate and the base, a lower active bevel gear fixed on the outer wall of the lower end of the shaft, an upper active bevel gear slidably mounted on the outer wall of the upper end of the shaft, and a servo motor mounted on the top of the top plate for driving the shaft to rotate.

Lower pulleys are rotatably mounted on both sides of the front end of the sliding frame, and a lower track is installed between the two lower pulleys. A lower driven bevel gear is rotatably mounted on the right side of the rear end of the sliding frame and fixed to the right lower pulley. The lower driven bevel gear meshes with the lower driving bevel gear for transmission.

[0009] The upper traction assembly includes an upper slide fixed between the lower ends of the outer walls of the two uprights. Upper pulleys are rotatably mounted on both sides of the front end of the upper slide, and an upper track is installed between the two upper pulleys. An upper driven bevel gear is rotatably mounted on the right side of the rear end of the upper slide and fixed to the upper pulley on the right side. The upper driven bevel gear meshes with the upper driving bevel gear for transmission. A connecting piece is fixed to the right end of the upper slide and rotatably connected to the upper driving bevel gear.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a cable construction auxiliary device, including a base 1, a traction mechanism 2 for cable traction on the base 1, and a moving mechanism 3 for overall movement on the base 1. The traction mechanism 2 includes:

[0026] The main component 21 includes uprights 211 fixed on both sides of the top of the base 1, a top plate 212 fixed between the tops of the uprights 211, a shaft 213 rotatably mounted between the top plate 212 and the base 1, a lower drive bevel gear 214 fixed on the lower outer wall of the shaft 213, an upper drive bevel gear 215 slidably mounted on the upper outer wall of the shaft 213, and a servo motor 216 mounted on the top of the top plate 212 for driving the shaft 213 to rotate.

[0027] The lower traction assembly 22 includes a lower slide frame 221 fixed between the lower ends of the outer walls of the two side uprights 211. Lower pulleys 222 are rotatably mounted on both sides of the front end of the lower slide frame 221. A lower track 223 is installed between the two lower pulleys 222. A lower driven bevel gear 224 is rotatably mounted on the right side of the rear end of the lower slide frame 221 and fixed to the right lower pulley 222. The lower driven bevel gear 224 meshes with the lower driving bevel gear 214 for transmission.

[0028] The upper traction assembly 23 includes an upper slide 231 fixed between the lower ends of the outer walls of the two side uprights 211. Upper pulleys 232 are rotatably mounted on both sides of the front end of the upper slide 231. An upper track 233 is installed between the two upper pulleys 232. An upper driven bevel gear 234 is rotatably mounted on the right rear end of the upper slide 231 and fixed to the right upper pulley 232. The upper driven bevel gear 234 meshes with the upper driving bevel gear 215 for transmission. A connecting piece 235 is fixed to the right end of the upper slide 231 and rotatably connected to the upper driving bevel gear 215.

[0029] In this embodiment, the output end of the servo motor 216 drives the shaft 213 to rotate. The shaft 213 drives the lower pulley 222 to rotate through the lower active bevel gear 214 and the lower driven bevel gear 224. This causes the lower pulleys 222 on both sides to drive the lower track 223 to move. At the same time, when the shaft 213 rotates, it also drives the upper pulley 232 to rotate through the upper active bevel gear 215 and the upper driven bevel gear 234. This causes the upper pulleys 232 on both sides to drive the upper track 233 to move. This allows the lower track 223 to work with the upper track 233 to pull the cable. This allows the lower traction component 22 and the upper traction component 23 to work together synchronously with a single servo motor 216, ensuring that the cable receives a uniform traction force. Furthermore, when the operator adjusts the distance between the upper slide 231 and the lower slide 221 using the handwheel screw 218 to accommodate different cable diameters, the transmission system of the upper traction component 23 can still maintain normal operation without interrupting the traction operation.

[0030] This ensures the continuity and reliability of power transmission during height adjustments. This intelligent transmission system not only simplifies the operation process but also ensures stable traction performance under different cable diameter conditions.

[0031] Specifically, the main body component 21 also includes a handwheel screw 218 that is threaded through and mounted on the top plate 212, and the lower end of the handwheel screw 218 is rotatably connected to the upper slide 231.

[0032] In this embodiment, rotating the handwheel screw 218 can drive the upper slide 231 to adjust its height along the upright 211, ensuring that the distance between the upper traction component 23 and the lower traction component 22 can be flexibly set according to different cable diameters; and the height adjustment process will not affect the normal operation of the traction mechanism at all.

[0033] Specifically, the main body component 21 also includes a keyway 217 formed on the outer wall of the shaft 213, and the shaft 213 is slidably connected to the upper drive bevel gear 215 through the keyway 217.

[0034] In this embodiment, the keyway 217 ensures that the upper drive bevel gear 215 can slide freely along the shaft 213 axially, while the key connection ensures the reliability of torque transmission; this sliding connection method makes the height adjustment of the upper traction assembly 23 smoother.

[0035] Specifically, the traction mechanism 2 also includes a threaded seat 24 fixed to the top rear end of the base 1, and a threaded rod 25 is installed inside the upper end of the threaded seat 24 with a thread through thread.

[0036] In this embodiment, the height of the upper slide 231 can be adjusted by rotating the threaded rod 25, thereby limiting the lowest working position of the upper slide 231; this avoids excessive pressure on the cable by the upper track assembly 23 and effectively protects the cable outer sheath from damage.

[0037] Specifically, the traction mechanism 2 also includes a main protective cover 26 fixed to the outside of the top plate 212, a secondary protective cover 27 fixed to the outside of the lower slide 221 and the upper slide 231, a meter counter 28 installed at one end of the secondary protective cover 27, and an electrical control cabinet 29 set on one side of the top of the base 1.

[0038] In this embodiment, the main protective cover 26 and the secondary protective cover 27 effectively isolate the interference of external dust and debris on the transmission components; the integrated installation of the meter counter 28 enables accurate measurement of cable length during construction, providing data support for project management; the reasonable layout of the electrical control cabinet 29 enables centralized management of the electrical control system, which not only facilitates operators to monitor the equipment operating status, but also ensures electrical safety.

[0039] Specifically, the moving mechanism 3 includes a frame 31 fixed to the bottom of the base 1, with wheels 32 installed on both sides of the left end of the frame 31, and a handle 33 fixed to the right end of the frame 31.

[0040] In this embodiment, the wheel 32 enables smooth rolling, and the handle 33 allows the device to be easily pushed or pulled, facilitating rapid transfer between different construction sites.

[0041] The working principle and usage process of this utility model are as follows: First, the output end of the servo motor 216 drives the shaft 213 to rotate. The shaft 213 drives the lower pulley 222 to rotate through the lower active bevel gear 214 and the lower driven bevel gear 224. This causes the lower pulleys 222 on both sides to drive the lower track 223 to move. At the same time, when the shaft 213 rotates, it also drives the upper pulley 232 to rotate through the upper active bevel gear 215 and the upper driven bevel gear 234. This causes the upper pulleys 232 on both sides to drive the upper track 233 to move. This allows the lower track 223 to work with the upper track 233 to pull the cable.

[0042] Furthermore, rotating the handwheel screw 218 allows for height adjustment of the upper slide 231 along the upright 211, ensuring that the distance between the upper traction component 23 and the lower traction component 22 can be flexibly set according to different cable diameters. A single servo motor 216 can synchronously drive the lower traction component 22 and the upper traction component 23 to work together, ensuring uniform traction force on the cable. Moreover, when the operator adjusts the distance between the upper slide 231 and the lower slide 221 using the handwheel screw 218 to accommodate different cable diameters, the transmission system of the upper traction component 23 continues to operate normally without interrupting the traction operation, ensuring the continuity and reliability of power transmission during height adjustment. This intelligent transmission system not only simplifies the operation process but also ensures stable traction performance under different cable diameter conditions.
