Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and more specifically to a cable laying and conveying device. Background Technology

[0002] Cable laying and conveying devices are mainly used for pulling power cables and communication cables, enabling mechanized laying of large-section, long-distance cables, thereby greatly improving construction quality and efficiency. However, existing cable laying and conveying devices have been found to have the following problems in actual construction applications: due to the height difference in the terrain where cables are laid, the cable laying and conveying device may cause the cables to bend during transport.

[0003] Specifically, when laying cables from higher to lower terrain, if there is a significant difference in elevation between the outlet height of the cable laying and conveying device and the extension direction of the downstream cable, the cable will be forced to bend downwards at a large bending angle after being led out. If the cable is laid from lower to higher terrain, it needs to be led out at an upward angle, which will also generate abnormal bending stress, causing mechanical damage to the cable and affecting safe operation.

[0004] The existing cable laying and conveying equipment has not improved or solved this problem, which greatly limits the application of cable laying and conveying equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a cable laying and conveying device, which at least partially solves one of the technical problems in the related art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cable laying and conveying device includes a main frame, on which an inlet end, a traction mechanism and an outlet end are arranged sequentially from front to back. The traction mechanism conveys the cable from front to back. The cable enters from the inlet end, is conveyed by the traction mechanism, and is led out from the outlet end. The main frame is also provided with a cable auxiliary support mechanism at the cable outlet. The cable auxiliary support mechanism includes an extension frame. The front end of the extension frame is rotatably connected to the main frame through a pivot. The rear end of the extension frame is suspended to the outside of the main frame, so that the extension frame can swing up and down around the pivot. An angle adjustment and holding structure is also provided between the extension frame and the main support to adjust the swing angle of the extension frame and keep the position of the extension frame fixed after the angle is adjusted to the correct position.

[0007] Furthermore, the angle adjustment and holding structure includes a pull rope, one end of which is connected to the rear end of the extension frame, and the other end of which is connected to a pull rope connection point on the main frame. By adjusting the length of the pull rope, the swing angle of the extension frame can be adjusted.

[0008] Furthermore, the main frame includes a bottom plate and a top plate arranged correspondingly at the top and bottom. The top plate and the bottom plate are supported by columns arranged at the four corners, and an installation space for the traction mechanism is formed between the top plate and the bottom plate.

[0010] Furthermore, the front end of the extension frame is rotatably connected to the column at the rear end of the main frame via a pivot. The pull rope connection point is a pull rope protrusion fixedly installed in the middle of the top plate. A pull rope through hole is provided at the rear end of the top plate. The pull rope passes through the pull rope through hole and is wrapped around the pull rope protrusion.

[0011] Furthermore, the traction mechanism includes an upper belt roller unit and a lower belt roller unit arranged opposite each other, forming a cable conveying channel between the upper belt roller unit and the lower belt roller unit.

[0012] Furthermore, an upper and lower belt roller unit is provided with an adjustable vertical spacing structure to adjust the vertical distance between the upper and lower belt roller units.

[0014] Furthermore, the vertical moving mechanism includes a threaded rod extending in the vertical direction, a rotating seat is provided at the main frame, the threaded rod passes through the rotating seat and is rotatably connected to it; an operating part is fixed at the upper end of the threaded rod; a nut seat is fitted on the threaded rod and is threadedly connected to it, and the nut seat is fixedly connected to the slider as a moving part.

[0015] Furthermore, the upper belt roller unit includes two upper belt rollers arranged on the back of the movable plate, and an upper conveyor belt is provided outside the two upper belt rollers. One of the upper belt rollers serves as the upper drive belt roller, and the upper drive belt roller is connected to the upper belt roller power unit.

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0021] like Figures 1 to 2 As shown, this embodiment provides a cable laying and conveying device, including a main frame 1. The main frame 1 includes a bottom plate 2 and a top plate 3 arranged vertically. The top plate and the bottom plate are supported by columns arranged at the four corners, forming an installation space between the top plate and the bottom plate. The bottom plate 2 is also provided with rollers for movement on its underside.

[0022] The front opening of the installation space serves as the cable inlet, and the rear opening serves as the cable outlet. A traction mechanism is installed within the installation space to transport the cable from front to back. During operation, the cable enters through the inlet, is transported by the traction mechanism, and exits through the outlet.

[0023] The main frame 1 is equipped with a cable auxiliary support mechanism at the cable outlet. The cable auxiliary support mechanism includes an extension frame 5. The front end of the extension frame 5 is rotatably connected to a column at the rear end of the main frame via a pivot 4. The rear end of the extension frame 5 is suspended to the outside of the main frame, allowing the extension frame 5 to swing up and down around the pivot. An angle adjustment and holding structure is also provided between the extension frame 5 and the main support to adjust the swing angle of the extension frame and keep the position of the extension frame fixed after the angle is adjusted.

[0024] In this embodiment, the angle adjustment and holding structure includes a pull rope 6. One end of the pull rope 6 is connected to the rear end of the extension frame 5, and the other end of the pull rope is connected to the pull rope connection point on the main frame. By adjusting the length of the pull rope, the swing angle of the extension frame can be adjusted.

[0025] Specifically, the pull rope connection point is a pull rope protrusion fixed in the middle of the top plate, and a pull rope through hole is provided at the rear end of the top plate 3. The pull rope passes through the pull rope through hole and is wrapped around the pull rope protrusion.

[0026] When encountering terrain with varying elevations during cable laying, pull rope 6 is activated, causing extension frame 5 to rotate and tilt. After determining the tilt angle, one end of pull rope 6 is tied to the pull rope protrusion to fix extension frame 5. At this point, extension frame 5 is suspended outside the device. Cables pass through extension frame 5 during cable transport, providing extended auxiliary support to prevent external bending damage to the cable, increasing the effectiveness of safe cable transport, and enabling adaptable operation in different terrain environments.

[0027] The traction mechanism includes an upper belt roller unit 12 and a lower belt roller unit 22 arranged opposite each other, forming a cable conveying channel between them. Furthermore, an adjustable vertical spacing structure is provided between the upper belt roller unit 12 and the lower belt roller unit 22 to adjust the vertical distance between them, accommodating cables of different diameters.

[0028] Specifically, the upper and lower spacing adjustment structure includes a fixed plate 7, a movable plate 10, a vertical guide rail 8, and a vertical moving mechanism. The lower belt roller unit 22 is installed on the back of the fixed plate 7, and the fixed plate 7 is fixedly connected to the base plate 2. The upper belt roller unit 12 is installed on the back of the movable plate 10.

[0029] Two vertical guide rails 8 are provided in parallel, both in the form of guide columns extending in the vertical direction. Both vertical guide rails 8 are fixedly connected to the base plate 2 of the main frame 1. A slider 9 is provided on the vertical guide rail 8 and is slidably connected to it. The slider 9 is fixedly connected to the movable plate 10.

[0030] The vertical moving mechanism includes a threaded rod 14 extending in the vertical direction, located between two vertical guide rails 8. A rotating seat 15 is fixedly installed on the top plate 3 at a position corresponding to the threaded rod 14, through which the threaded rod 14 passes and is rotatably connected. A turntable 16 is fixed to the upper end of the threaded rod 14, and the exterior of the turntable 16 is provided with anti-slip texture. A nut seat 13 is fitted onto the threaded rod 14 and is threadedly connected to it, serving as a moving part and fixedly connected to the slider 9.

[0031] In this embodiment, the pull rope protrusions are also provided at both ends of the rotating seat 15.

[0032] When the upper and lower spacing adjustment structure is in operation, the worker holds the turntable 16 and rotates it. When the turntable 16 rotates, it drives the threaded rod 14 to rotate. Since the threaded rod 14 is rotatably connected to the nut seat 13, the rotation of the threaded rod 14 can drive the nut seat 13 to rise and fall and the slider 9 to rise and fall, thereby driving the movable plate 10 to rise and fall. The distance between the upper belt roller unit 12 and the lower belt roller unit 22 is adjusted by the rise and fall of the movable plate 10 to accommodate cables of different diameters.

[0033] The working principle of this invention is as follows: Place the device on the ground, insert the cable between the upper roller unit 12 and the lower roller unit 22, and rotate the turntable 16 to move the upper roller unit 12 down and clamp the cable.

[0034] Pull the rope 6 according to the terrain to be laid, so that the extension frame 5 will rotate and tilt. After determining the tilt angle, tie one end of the rope 6 to the rotating seat 15 to fix the extension frame 5. At this time, the extension frame 5 is suspended outside the device. When the cable is transported, it passes through the extension frame 5 to provide extension and auxiliary support for the cable during transport and prevent the cable from being bent or damaged.

[0035] Start the upper belt roller unit 12 and the lower belt roller unit 22 to lay the cable. Example 2

[0036] like Figures 2 to 4 As shown, this embodiment, based on embodiment one, provides a detailed description of the specific structure and arrangement of the upper belt roller unit 12 and the lower belt roller unit 22.

[0037] In this embodiment, the upper belt roller unit 12 includes two upper belt rollers arranged on the back of the movable plate 10. An upper conveyor belt (a rubber track) is provided outside the two upper belt rollers. The upper belt roller near the inlet end serves as the upper active belt roller. The upper active belt roller is connected to the upper belt roller power unit, and the upper conveyor belt moves counterclockwise through the upper belt roller power unit.

[0038] Specifically, the upper belt roller power unit includes an upper empty chamber 171 corresponding to the position of the upper drive belt roller, and the upper empty chamber 171 is fixed to the front of the movable plate 10. One end of the upper drive belt roller extends into the interior of the upper empty chamber 171 and is fixed with a first upper bevel gear 20.

[0039] The lower belt roller unit 22 includes two lower belt rollers arranged on the back of the fixed plate 7. A lower conveyor belt (a rubber track) is provided outside the two lower belt rollers. The lower belt roller near the inlet end serves as the lower drive belt roller. The lower drive belt roller is connected to the lower belt roller power unit, which realizes the counterclockwise movement of the lower conveyor belt.

[0040] Specifically, the lower belt roller power unit includes a lower empty chamber 172 corresponding to the position of the lower drive belt roller, and the lower empty chamber 172 is fixed to the front of the fixed plate 7. One end of the lower drive belt roller extends into the interior of the lower empty chamber 172 and is fixed with a first lower bevel gear 20.

[0041] The vertical drive shaft 18 passes through the upper empty chamber 171 and the lower empty chamber 172. The main frame 1 is equipped with a motor, which drives the vertical drive shaft 18 to rotate. The vertical drive shaft 18 is a splined shaft structure with multiple vertical ridges 19.

[0042] A second upper bevel gear 21 is rotatably connected to the top of the upper cavity 171, and the second upper bevel gear 21 meshes with the upper side of the first upper bevel gear 20. The center of the second upper bevel gear 21 is provided with a spline groove and has multiple vertical grooves 23. The vertical drive shaft 18 passes through the spline groove of the second upper bevel gear 21, and the protrusion 19 is located inside the groove 23.

[0043] The engagement of the protrusion 19 and the groove 23 serves two purposes: first, it ensures that the second upper bevel gear 21 can move up and down outside the vertical drive shaft 18; second, since the protrusion 19 is always stuck inside the groove 23, the rotation of the vertical drive shaft 18 will drive the second upper bevel gear 21 to rotate.

[0044] A second lower bevel gear 11 is rotatably connected to the bottom of the lower empty compartment 172, and the second lower bevel gear 11 meshes with the lower side of the first lower bevel gear. The vertical drive shaft 18 passes through the second lower bevel gear 11 and is fixedly connected to it.

[0045] The starter motor drives the vertical drive shaft 18 to rotate. The vertical drive shaft 18, through the second upper bevel gear 21 and the first upper bevel gear 20, drives the upper drive roller 11 to rotate, thereby causing the upper conveyor belt to move counterclockwise. Simultaneously, the vertical drive shaft 18, through the second lower bevel gear 11 and the first lower bevel gear, drives the lower drive roller to rotate, thereby causing the lower conveyor belt to move clockwise. This achieves synchronous counter-clockwise motion between the upper and lower drive roller power units. Example 3

[0046] In this embodiment, the upper belt roller unit 12 and the lower belt roller unit 22 can each be connected to a set of drive motors and transmission components to achieve independent driving.
