Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying device for integrated construction of cable trays. Background Technology

[0002] When constructing photovoltaic power stations in complex geological conditions such as the Gobi Desert, traditional direct burial of cables is prone to problems such as wear and tear on the cable sheath, insulation cracking, and even line breakage due to loose and unstable fine sand and ground subsidence caused by seasonal temperature differences. This seriously threatens the long-term reliability of photovoltaic power stations. Therefore, most projects currently use cable trays for suspended cable laying to avoid geological risks. However, existing laying equipment has significant shortcomings in adapting to changes in cable tray height and coordinating the operation of multiple cable specifications. The mismatch between equipment and integrated construction requirements in traditional technical systems is becoming increasingly prominent.

[0003] Referring to the power cable laying device disclosed in patent announcement number CN221669425U, which adjusts the distance between the first and second guide rollers by rotating a ball screw, and in conjunction with the receiving groove on the outer wall of the guide roller, it can clamp and guide cables of different specifications. However, this device still has the following limitations: On the one hand, the shape of the receiving groove of the guide roller is fixed, and it can only be adapted to specific cables that match the groove shape (such as circular cross-sections). It lacks compatibility with flat cables or cables with irregular cross-sections, thus limiting its application range. On the other hand, during cable transportation, its outer wall is prone to contact with the lower end of the support frame on which the guide rollers are installed. Even if the distance between the guide rollers is adjustable, the fixing structure at the bottom of the support frame may still cause scratches on the outer sheath of the cable due to friction. Especially in the strong sand and dust environment of the Gobi Desert, particle accumulation can easily aggravate wear and further reduce the practicality of the equipment. Utility Model Content

[0004] In view of the fact that although the existing cable laying device can adjust the spacing of the guide rollers to adapt to some cable specifications, the fixed shape of the guide roller receiving groove and the easy contact and friction between the bottom of the support frame and the cable result in insufficient compatibility with irregularly shaped cables and easy damage to the outer sheath of the cable, especially in complex environments such as the Gobi Desert, the present invention is proposed.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a cable laying device for integrated construction of cable trays, including a base, a support plate on one side of the top of the base, a motor fixedly installed on one side of the support plate, a cable reel connected to the motor rotatably installed on the other side of the support plate, a guide conveying mechanism connected to one side of the base through a support assembly, and a rotating assembly on one side of the support assembly;

An adjusting screw is rotatably installed in the sliding groove. A slider is threadedly connected to the outer wall of the adjusting screw, and the slider is rotatably connected to both ends of the upper guide roller.

[0007] As a preferred embodiment, the guiding and conveying mechanism further includes a synchronous wheel, which is sleeved on the outer wall of the top end of the adjusting screw that passes through the support frame.

The lower sliding groove is symmetrically provided with a second slider. The upper sliding groove is rotatably installed with a bidirectional screw. The outer wall of the bidirectional screw is symmetrically connected with a third slider.

The support frame is fixedly installed with a second motor, and the output end of the second motor is connected to one end of the lower guide roller.

[0008] As a preferred embodiment, a pointer is fixedly connected to the inner wall of one side of the slider, and a scale value adapted to the pointer is provided on one side of the front of the support frame.

[0009] As a preferred embodiment, the inner wall of the slider three is fixedly connected to the pointer two, and the upper part of the front of the support frame is provided with a scale value two that matches the pointer two.

[0010] As a preferred embodiment, the second guide roller is perpendicular to the first guide roller, and both the first guide roller and the second guide roller are covered with a rubber layer on their outer walls.

[0011] As a preferred embodiment, the support assembly includes a sleeve disposed on one side of the top of the base. A guide rod is fixedly installed at the bottom of the sleeve, and a telescopic rod is slidably sleeved on the outside of the guide rod.

A connecting ring is rotatably embedded in the top of the sleeve, and a drive disc is connected to the upper end of the connecting ring at the top of the sleeve. The inner wall of the drive disc is threadedly connected to the outer wall of the telescopic rod.

[0012] As a preferred embodiment, the guide rod has a hexagonal prism structure, and the outer wall of the drive disc is symmetrically provided with several handles.

[0013] As a preferred embodiment, the connecting ring has a convex cross-section, and the top of the sleeve has an annular groove that matches the connecting ring.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-4 As shown, a cable laying device for integrated construction of cable trays is provided, including a base 1, a support plate 2 on one side of the top of the base 1, a motor 3 fixedly installed on one side of the support plate 2, a cable reel 4 connected to the motor 3 rotatably installed on the other side of the support plate 2, a guide conveying mechanism connected to one side of the base 1 through a support assembly, and a rotating assembly on one side of the support assembly.

[0028] The guiding and conveying mechanism includes a support frame 5. Two guide rollers 6 are arranged vertically on the front side of the support frame 5, and guide rollers 17 are symmetrically arranged behind the guide rollers 6. A groove 9 is symmetrically opened on the inner wall of the front end of the support frame 5. An adjusting screw 7 is rotatably installed in the groove 9. A slider 8 is threadedly connected to the outer wall of the adjusting screw 7, and the slider 8 is rotatably connected to both ends of the guide rollers 6 located above. Through the guiding and conveying mechanism, the guide rollers 6 can be driven to rotate by a motor 12, thereby conveying the cable. By rotating the adjusting screw 7 and the bidirectional screw 18, the distance between the two guide rollers 6 and the distance between the two guide rollers 17 can be adjusted, thus adapting it to guide and convey cables of different diameters, broadening its applicability. Furthermore, the vertically distributed guide rollers 6 and 17 prevent the cable from being scratched by the lower structure of the support frame 5, making it convenient to use.

[0029] In this example, the guiding and conveying mechanism also includes a synchronous wheel 10, which is sleeved on the outer wall of the top end of the adjusting screw 7 that passes through the support frame 5. The two synchronous wheels 10 are connected by a synchronous belt 11. The inner wall of the rear end of the support frame 5 is symmetrically provided with a second slide groove 14. The lower slide groove 14 is symmetrically provided with a second slider 15. The upper slide groove 14 is rotatably installed with a bidirectional screw 18. The outer wall of the bidirectional screw 18 is symmetrically connected with a third slider 16. The second guide roller 17 is located between the second slider 15 and the third slider 16, and both ends of the second guide roller 17 are rotatably connected to the second slider 15 and the third slider 16, respectively. The second motor 12 is fixedly installed on one side of the support frame 5, and the output end of the second motor 12 is connected to one end of the first guide roller 6 located below. Through the transmission design of the synchronous wheel 10 and the synchronous belt 11, the synchronous rotation of the two adjusting screws 7 can be realized, improving the adjustment efficiency, reducing manual operation errors, and further enhancing the adaptability to cables of different specifications.

[0030] In this example, a pointer 13 is fixedly connected to the inner wall of one side slider 8, and a scale value 1 that matches the pointer 13 is provided on one side of the front of the support frame 5. The cooperation between the pointer 13 and the scale value 1 can intuitively display the specific value of the spacing adjustment of the guide roller 6, which is convenient for precise control of the adjustment amount and improves the convenience of operation and adjustment accuracy.

[0031] In this example, a pointer 19 is fixedly connected to the inner wall of slider 3 16, and a scale value 2 that matches pointer 2 19 is provided on the upper front of support frame 5. The setting of pointer 2 19 and scale value 2 can clearly provide feedback on the real-time data of guide roller 2 17 spacing adjustment, realize the visual and precise adjustment of guide roller spacing in the horizontal and vertical directions, and further improve the applicability of the equipment.

[0032] In this example, guide roller 2 17 is vertically distributed with guide roller 1 6, and both guide roller 1 6 and guide roller 2 17 are covered with a rubber layer on their outer walls. The vertically distributed guide roller 1 6 and guide roller 2 17 can form a bidirectional limit on the cable in both horizontal and vertical directions. The rubber layer increases the friction, prevents the cable from deviating, reduces wear on the outer wall, and improves the stability and safety of the guiding and conveying.

[0033] In this example, the support assembly includes a sleeve 20, which is located on one side of the top of the base 1. A guide rod 21 is fixedly installed at the bottom of the sleeve 20, and a telescopic rod 22 is slidably sleeved on the outside of the guide rod 21. The upper end of the telescopic rod 22 is fixedly connected to the support frame 5. A connecting ring 24 is rotatably embedded in the top of the sleeve 20, and a drive disc 23 is connected to the top of the sleeve 20 at the upper end of the connecting ring 24. The inner wall of the drive disc 23 is threadedly connected to the outer wall of the telescopic rod 22. Through the structure of the sleeve 20, guide rod 21, telescopic rod 22 and drive disc 23 of the support assembly, the telescopic rod 22 can be raised and lowered by rotating the drive disc 23, thereby flexibly adjusting the height of the support frame 5, accurately adapting to cable trays of different heights, reducing the tedious operation of manual disassembly and reassembly, and improving construction efficiency.

[0034] In this example, the guide rod 21 has a hexagonal prism structure, and several handles are symmetrically provided on the outer wall of the drive disk 23; the hexagonal prism guide rod 21 can prevent the telescopic rod 22 from rotating and ensure the stability of the lifting process; the handle design of the drive disk 23 makes it easy to apply force manually, making the height adjustment operation more labor-saving and convenient.

[0035] In this example, the cross-section of the connecting ring 24 is convex, and the top of the sleeve 20 is provided with an annular groove that fits the connecting ring 24. The fit between the convex connecting ring 24 and the annular groove can enhance the structural stability when the drive disc 23 rotates, prevent the sleeve 20 from shaking with the telescopic rod 22, and ensure the reliability of height adjustment.

[0036] In this example, the rotating assembly includes a motor 25, which is fixedly installed on one side of the top sleeve 20 of the base 1. The output end of the motor 25 is connected to a gear 26, and a gear ring 27 is meshed on one side of the gear 26. The gear ring 27 is sleeved on the outer wall of the sleeve 20. The lower end of the sleeve 20 is rotatably connected to the base 1 through a bearing. Through the transmission of the motor 25, gear 26 and gear ring 27 of the rotating assembly, the sleeve 20 can be automatically rotated, thereby driving the support frame 5 to rotate, flexibly changing the guide and conveying angle, adapting to complex working conditions such as bending or turning of the cable tray, and reducing the amount of manual adjustment work.

[0037] In this example, the diameter of gear 26 is smaller than the diameter of gear ring 27; the gear transmission design between gear 26 and gear ring 27 can achieve a speed reduction and torque increase effect, making the support frame 5 rotate more smoothly, facilitating precise control of the adjustment range of the guide conveying angle, and improving the stability and accuracy of equipment operation.

[0038] During use, cable unwinding and guiding / conveying:

[0039] Motor 13 drives the cable reel 4 to rotate, releasing the cable. After the cable enters the support frame 5, motor 212 drives the lower guide roller 6 to rotate, pulling the cable forward through friction. At the same time, the screw 7 can be adjusted manually or through the synchronous pulley 10 and synchronous belt 11 to move the slider 8 up and down, adjusting the distance between the upper and lower guide rollers 6. Rotating the bidirectional screw 18 moves the guide roller 17 horizontally through the slider 316, adjusting the distance between the two guide rollers 17, thus adapting to bidirectional limiting guidance for cables of different diameters. The guide rollers 6 and 17 are vertically distributed, and the outer rubber layer can reduce cable wear. Pointer 13 / scale value 1 and pointer 29 / scale value 2 assist in precise adjustment of the distance.

[0040] Adjusting the height of support frame 5:

[0041] When the height of the cable tray needs to be adjusted, the drive disc 23 is rotated, and its inner thread engages with the telescopic rod 22, causing the telescopic rod 22 to slide up and down along the hexagonal guide rod 21, thereby raising and lowering the height of the support frame 5. The guide rod 21 prevents the telescopic rod 22 from rotating, ensuring smooth lifting and lowering. The U-shaped connecting ring 24 engages with the ring groove to enhance the structural stability of the drive disc 23 when it rotates.

[0042] Guide angle rotation adjustment:

[0043] After the motor 25 starts, it drives the gear 26 and the gear ring 27 through meshing transmission. Since the diameter of the gear 26 is smaller than the diameter of the gear ring 27, it reduces speed and increases torque, drives the sleeve 20 to rotate around the base 1, and drives the support frame 5 to rotate, changing the angle of cable guiding and conveying. This adapts to complex paths such as cable tray turns or inclinations, eliminating the need for manual handling of the equipment to adjust its direction.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
