Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction engineering, in particular to an auxiliary traction device for laying municipal cables. Background Art

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, cable laying methods can be categorized as overhead, underground (in pipes and direct burial), underwater, on walls, and in tunnels. Choosing the right cable laying method is crucial to ensuring transmission quality, reliability, and maintenance.

[0003] Cable laying is a critical and tedious task in municipal construction projects. During this process, multiple workers collaborate to guide the cables into underground shafts. However, the complexity of underground shafts presents significant challenges for cable pulling and laying. Existing manual pulling methods are often inefficient and prone to damage, especially at pipe corners, due to the limited bending radius of the cables and increased friction in the shafts. Therefore, developing an auxiliary device that can effectively guide and pull cables around underground shaft corners is crucial. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides an auxiliary traction device for laying municipal cables, which solves the problems of difficulty and low efficiency in traction at corners when laying cables in underground pipelines in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An auxiliary traction device for laying municipal cables comprises a right-angled main frame, a 90-degree arc-shaped traction trough provided on the front of the main frame, multiple sets of traction wheels with grooves evenly mounted inside the traction trough, symmetrically provided with adjustable limit assemblies near the left and right ends of the front of the traction trough, and a traction mechanism for pulling the cable fixed to the right end of the traction trough.

[0007] The traction mechanism includes a fixed frame, a traction belt, a roller, a motor, a driving gear and a driven gear. The fixed frame is welded and fixed to the right end of the traction groove, and the fixed frame is configured as a C-shaped structure. Multiple groups of rollers are provided on the upper and lower sides of the fixed frame. Multiple groups of roller sleeves are provided with traction belts for transmission. The front end of the roller shaft on the far right is equipped with a driven gear. The driven gear is meshed and connected to the driving gear, and the driving gear is driven by the motor.

[0008] Furthermore, a rotatable screw is vertically arranged at the front corner of the main frame, a handle is installed on the upper end of the screw, and a threaded slider is fixed on the back of the traction groove. The threaded slider is sleeved on the screw and is screwed together with the screw by a thread.

[0009] Furthermore, the main frame is provided with limiting guide rods near the left and right ends, and the traction groove is slidably connected to the limiting guide rods through a slide plate.

[0010] Furthermore, a guide wheel for supporting and guiding the cable is fixedly provided at the left end of the main frame, and the specifications of the guide wheel are the same as those of the traction wheel.

[0011] Furthermore, the limiting assembly includes a groove frame, a limiting pressure wheel, a connecting plate, a slide groove and a bolt. The groove frame is a U-shaped structure and is arranged at intervals on the outside of the traction groove. A freely rotatable limiting pressure wheel is installed inside the groove frame. Connecting plates are welded at the upper and lower ends of the groove frame. A slide groove is opened inside the connecting plate. Bolts are installed inside the slide groove. The connecting plate is adjustably connected to the traction groove through the bolts.

[0012] Furthermore, the main frame is fixedly installed at the corner of the wall by expansion bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The right-angle main frame design and the 90-degree arc-shaped traction groove in the utility model match the corners of the wall, allowing the cable to turn smoothly, reducing the risk of damage due to a small bending radius, thereby improving laying efficiency. At the same time, the traction mechanism is set to realize automatic traction of the cable, greatly reducing the labor intensity of workers and reducing the risk of damage to the cable due to improper manual traction.

[0015] 2. The utility model uses the design of the screw and the threaded slider to enable the height of the traction trough to be adjusted according to actual needs to adapt to the laying requirements of cables at different heights. At the same time, the design of the limit guide rod and the slide plate ensures the stability of the traction trough during the adjustment process, provides a stable guide for the up and down movement of the traction trough, and ensures the stability and accuracy of the cable laying process.

[0016] 3. The utility model can laterally limit the cable through the positioning assembly to prevent it from falling due to gravity and deviating from the predetermined trajectory during traction, thereby ensuring the accuracy and safety of cable laying. The slide groove and bolts in the limiting assembly enable the limiting assembly to be adjusted within a certain range to adapt to cables of different diameters and provide different clamping forces.

[0017] 4. In the utility model, multiple sets of traction wheels with grooves are evenly installed inside the traction trough, which can reduce the friction resistance during cable traction and avoid wear and damage to the cable. The setting of the guide wheel provides additional support and guidance for the cable, ensuring that the cable is correctly guided and positioned before entering the traction trough, further improving the efficiency of cable laying.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figures 1 to 6As shown, a municipal cable laying auxiliary traction device includes a main frame 1 with a right-angle structure. The right-angle main frame 1 is designed so that the device can fit closely to the corner of the wall, providing stable support and guidance for the cable. A traction groove 4 with an arc structure is provided on the front side of the main frame 1, and its arc is 90 degrees, which matches the corner of the wall, ensuring that the cable can turn smoothly during the laying process and reducing the risk of damage to the cable due to a small bending radius. A plurality of groups of traction wheels 11 with grooves are evenly equipped inside the traction groove 4. The traction wheel 11 is used to pull and move the cable, which can reduce the friction resistance during the cable traction process and improve the laying efficiency of the cable. Adjustable limit components 3 are symmetrically provided near the left and right ends of the front side of the traction groove 4. The limit component 3 can limit the cable laterally to prevent it from deviating from the predetermined trajectory due to gravity falling during the traction process, thereby ensuring the accuracy and safety of cable laying. A traction mechanism 5 for pulling the cable is fixed at the right end of the traction groove 4 to realize automatic traction of the cable.

[0028] The traction mechanism 5 includes a fixed frame 51, a traction belt 52, a roller 53, a motor 54, a driving gear 55 and a driven gear 56. The fixed frame 51 is welded and fixed to the right end of the traction groove 4, and the fixed frame 51 is set to a C-shaped structure. Multiple groups of rollers 53 are provided on the upper and lower sides of the fixed frame 51. The multiple groups of rollers 53 are sleeved with traction belts 52 for transmission. The front end of the shaft of the rightmost roller 53 is equipped with a driven gear 56. The driven gear 56 is meshed and connected to the driving gear 55. The driving gear 55 is driven by the motor 54. The traction mechanism 5 is composed of a fixed frame 51, a traction belt 52, a roller 53, a motor 54 and other components, which realizes the automatic traction of the cable. The motor 54 drives the driving gear 55 to rotate, and drives the driven gear 56 and the roller 53 to rotate through the gear meshing transmission, thereby driving the traction belt 52 to move. The friction force of the two sets of traction belts 52 is used to drive the cable to move, thereby realizing the traction of the cable. The traction mechanism 5 greatly reduces the labor intensity of the workers, improves the laying efficiency, and reduces the risk of cable damage due to improper manual traction.

[0029] In this embodiment, a rotatable screw rod 10 is vertically mounted at the front corner of the main frame 1. A handle 7 is mounted on the upper end of the screw rod 10. A threaded slider 9 is fixed to the back of the traction trough 4. The slider 9 is sleeved onto the screw rod 10 and screwed to it via a threaded connection. The design of the screw rod 10 and the slider 9 allows the height of the traction trough 4 to be adjusted according to actual needs. By turning the handle 7 to rotate the screw rod 10, the slider 9 moves up and down on the screw rod 10, thereby adjusting the position of the traction trough 4 to accommodate the cable installation requirements at different heights.

[0030] In this embodiment, limiting guide rods 6 are provided near both left and right ends of the main frame 1, and the traction trough 4 is slidably connected to the limiting guide rods 6 via slides 8. The design of the limiting guide rods 6 and slides 8 ensures the stability of the traction trough 4 during adjustment, providing stable guidance for the up and down movement of the traction trough 4. The sliding connection between the slides 8 and the limiting guide rods 6 ensures that the traction trough 4 remains horizontal during up and down movement, preventing it from tilting due to gravity, thereby ensuring stability and accuracy during cable laying.

[0031] In this embodiment, a guide wheel 2 for supporting and guiding the cable is fixed to the left end of the main frame 1. The specifications of the guide wheel 2 are the same as those of the traction wheel 11. The installation of the guide wheel 2 provides additional support and guidance for the cable, supporting the cable from the left end of the main frame 1, ensuring that the cable is properly guided and positioned before entering the traction groove 4.

[0032] In this embodiment, the limiting assembly 3 comprises a trough frame 31, a limiting pressure wheel 32, a connecting plate 33, a slide 34, and a bolt 35. The trough frame 31 is a U-shaped structure, spaced apart outside the traction trough 4. The trough frame 31 is equipped with a freely rotatable limiting pressure wheel 32. Connecting plates 33 are welded to the top and bottom ends of the trough frame 31. The connecting plates 33 are internally provided with slides 34, which are internally provided with bolts 35. The connecting plates 33 are adjustably connected to the traction trough 4 via the bolts 35. The limiting assembly 3 can laterally limit the cable, preventing it from falling due to gravity and deviating from the intended trajectory during traction, thus ensuring accurate and safe cable laying. When the cable passes through, the limiting pressure wheel 32 presses on the cable, preventing it from shaking or jumping out of the traction trough 4. The slide 34 and bolt 35 also allow the limiting assembly 3 to be adjusted within a certain range to accommodate cables of different diameters and provide varying clamping forces.

[0033] In this embodiment, the main frame 1 is fixedly installed at the corner of the wall by means of expansion bolts 35. The fixing method of the expansion bolts 35 ensures a tight connection between the main frame 1 and the wall, and ensures the installation stability of the device.

[0034] The working principle of this auxiliary traction device for laying municipal cables is as follows: in actual use, the main frame 1 is first fixed to the corner of the wall using expansion bolts 35 to ensure stability. The height of the traction groove 4 is adjusted as needed to meet the height requirements of the cable laying. By turning the handle 7 to drive the screw 10 to rotate, the threaded slider 9 moves up and down on the screw 10 to adjust the position of the traction groove 4. The cable is placed on the guide wheel 2 and introduced from the guide wheel 2 to the traction wheel 11 in the traction groove 4. The cable is then bent along the traction groove 4 and led out from the traction mechanism 5. Two sets of limit assemblies 3 are connected to the traction groove 4. The limit pressure wheels 32 thereon are used to clamp and limit the cables to prevent them from shaking or jumping out of the traction groove 4. At the same time, the provided slide grooves 34 and bolts 35 enable the limit assemblies 3 to be adjusted within a certain range to accommodate cables of different diameters and provide different clamping forces. Then the motor 54 is started to drive the driving gear 55 to rotate, thereby driving the traction belt 52 to move. The traction belt 52 drives the cable to move through friction, thereby traction of the cable and starting the laying construction.

[0035] To sum up, the municipal cable laying auxiliary traction device can guide the cable smoothly through the corners of the underground shaft, reducing the risk of damage due to a small bending radius. It can not only improve the quality and efficiency of cable laying, but also reduce labor intensity and safety risks, providing strong technical support for municipal cable laying work.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
