[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] A cable conveyor is an electric machine for laying power cables. It is often used in conjunction with cable traction machines, hoists and other cable laying machines. For environments with more complex working conditions, existing linear cable conveyors are no longer used, and it is necessary to rely on turnable cable conveyors. The cable turning conveyor depends on the curvature of the belt during transportation. There are conveyors with specific curvature belts. For such conveyors with specific curvature belts, it can only be used for cable transportation of a certain size. In reality, cables with large size differences are often encountered. Directly using a turning conveyor will inevitably damage cables of inappropriate size.

[0037] In view of the above problems, reference Figures 1 to 4 As shown, the embodiment of the technical solution provides a cable laying equipment with adjustable cable turning radius, including: a base frame 100, a fixed crawler conveyor mechanism 200, and a crawler conveyor mechanism 300 with adjustable cable bending radius; wherein, the base frame 100 is a carrier of the entire conveyor, and is directly supported on the ground when in use, and a rectangular frame is usually adopted to ensure uniform and stable force; the crawler on the opposite side of the fixed crawler conveyor mechanism 200 and the crawler conveyor mechanism 300 with adjustable cable bending radius provides a cable conveying channel 400 and a friction driving force.

[0038] Specifically, the fixed crawler conveyor mechanism 200 is arranged on one side of the chassis 100, and the specific structure is the same as that of the prior art, and no structural improvement is made;

[0039] Therefore, the main improvement of the present solution lies in the cable bending radius adjustable crawler conveyor mechanism 300, which is arranged on the other side of the chassis 100 opposite to the fixed crawler conveyor mechanism 200 and a distance is maintained between the two to form a cable conveying channel 400, and the core function is to indirectly adjust the turning radius of the cable during conveying by changing the curvature of the crawler;

[0040] like Figure 5 , Figure 6 As shown, the cable bending radius adjustable crawler conveying mechanism 300 includes a mounting bracket 310, a crawler drive mechanism 320, a crawler 330, an elastic chain plate 340, and a turning radius adjustment device 350. The mounting bracket 310 is arranged on the base frame 100, the crawler drive mechanism 320 is fixed to the mounting bracket 310 and is connected to the crawler transmission, the elastic chain plate 340 is against the inner side of the crawler 330 and both ends are fixedly connected to the mounting bracket 310, and the turning radius adjustment device 350 has a telescopically adjustable drive shaft, and the drive shaft is used to act on the elastic chain plate 340 to change its curvature, and the crawler 330 and the elastic chain plate 340 change synchronously to change the cable turning radius; for the purpose of compact structure and beautiful appearance, a protective cover 370 is arranged on the top of the mounting bracket 310, and the crawler drive mechanism 320, the crawler 330, the elastic chain plate 340, and the turning radius adjustment device 350 are all located in the protective cover 370.

[0041] It can be seen that this solution is to improve one of the fixed crawler conveyor mechanisms 200 on the traditional conveyor into a crawler conveyor mechanism 300 with adjustable cable bending radius, which can be suitable for conveying cables of different sizes with turning radius, and can also realize straight-line conveying, greatly improving the applicable scope of the conveyor. Only one conveyor is needed for on-site operations to meet various conveying needs, and the curved crawler conveyor mechanism can provide a certain conveying force at the cable turning point, which can reduce the layout of the traction machine and improve the conveying efficiency. The cable turning radius adjustment and cable conveying can be carried out simultaneously without stopping the operation, and the conveying efficiency is guaranteed. The elastic chain plate 340 can ensure that the crawler 330 is evenly stressed when the drive shaft of the turning radius adjustment device 350 is adjusted, so as to realize the change of the cable turning radius. After the drive shaft retracts, the elastic chain plate 340 can restore the predetermined shape.

[0042] like Figure 7 , Figure 8As shown, in some embodiments of the present invention, the turning radius adjustment device 350 includes an adjusting handwheel 351, a box body 352, and a worm 353, a turbine 354, a ball nut 355, and a first screw 356 arranged in the box body 352, the adjusting handwheel 351 is fixedly connected to the input end of the worm 353, the box body 352 is fixed to the mounting bracket 310, the worm 353 is transmission-connected to the turbine 354, the ball nut 355 is coaxially fixed to the turbine 354 and transmission-connected to the first screw 356, and the first screw 356 is the driving shaft.

[0043] When working, the adjusting hand wheel 351 is rotated to drive the other fixed worm 353 to rotate synchronously, the worm 353 engages with the turbine 354 to realize the rotation of the turbine 354, and the ball nut 355 coaxially fixed with the turbine 354 rotates synchronously, and the first screw 356 matched with the ball nut 355 is transmitted to realize the extension and retraction movement. This turning radius adjustment device 350 adopts the adjustment hand wheel 351, worm 353, turbine 354, ball nut 355, first screw 356 and other structures, which is very labor-saving and accurate in adjustment. In addition, the turbine 354 and the ball nut 355 can also be provided with bearings 367 in the box 352 to reduce the friction during rotation. It should be pointed out that the above-mentioned turning radius adjustment device 350 is only one embodiment of the present application, and other existing devices that can realize the extension and retraction functions can also be used.

[0044] In order to facilitate accurate control of the track curvature when adjusting the turning radius, in some embodiments of the present invention, the cable bending radius adjustable track conveying mechanism 300 also includes a displacement indicating device 360, which is used to observe the position of the elastic chain plate 340 to indicate the cable turning radius corresponding to the track 330. Since the elastic chain plate 340 is attached to the inner side of the track 330, the position of the elastic chain plate 340 can be equivalent to the cable turning radius corresponding to the track 330.

[0045] like Figure 1 As shown, in some embodiments of the present invention, the displacement indicating device 360 ​​includes a strip observation window 361 and a displacement scale line 362, the strip observation window 361 is located at the top of the center of the elastic chain plate 340 and is perpendicular to the elastic chain plate 340, and the displacement scale line 362 is arranged on one side of the strip observation window. It should be noted that the strip observation window 361 and the displacement scale line 362 are a relatively low-cost implementation, and a combination of a position sensor, a single-chip microcomputer, and a display screen can also be used to achieve electronic indication.

[0046] Since the cable conveying channel 400 depends on the cable diameter, cables of different specifications require cable conveying channels 400 of different widths. Therefore, in some embodiments of the present invention, a track spacing adjustment component 500 is also included, and the track spacing adjustment component 500 includes a second screw rod 510, a first slide shaft 520, and a second slide shaft 530 arranged on the chassis 100. The second screw rod 510, the first slide shaft 520, and the second slide shaft 530 are all arranged between the cable bending radius adjustable crawler conveyor mechanism 300 and the fixed crawler conveyor mechanism 200, and the first slide shaft 520 and the second slide shaft 530 are located on the left and right sides of the second screw rod 510. The second screw rod 510 is respectively driven by the cable bending radius adjustable crawler conveyor mechanism 300 and the fixed crawler conveyor mechanism 200. When in use, a hand wheel or a motor drive mechanism can be installed at one end of the second screw rod 510 to rotate the second screw rod 510, so that the two crawler conveyor mechanisms are close to or away from each other, and the cable conveying channels 400 with different spacings are realized. Of course, the second screw rod 510 may also be directly clamped with a wrench for rotational adjustment.

[0047] like Figures 1 to 4 As shown, in some embodiments of the present invention, it also includes a first cable bracket 110 and a second cable bracket 120 arranged at the front and rear ends of the base frame 100. The first cable bracket 110 and the second cable bracket 120 are respectively connected to the input end and the output end of the cable transmission channel 400, and are used for support and protection during cable transmission.

[0048] Specifically, in some embodiments of the present invention, the first cable bracket 110 and the second cable bracket 120 have the same structure, both including a U-shaped frame 111, a lower bracket assembly 112, a left protection wheel 113, a right protection wheel 114, an upper limit wheel 115 and a lower limit wheel 116, which respectively implement support and protection from four directions: up, down, left and right. The U-shaped frame 111 is fixed on the base frame 100, and the lower bracket assembly 112 is installed at the lower part of the U-shaped frame 111 and has a lifting and lowering adjustment mechanism 117, which can realize its rising and falling, so as to be suitable for cables of different sizes. The lower limit wheel 116 is installed on the lower bracket assembly 112, and the two opposite inner sides of the U-shaped frame 111 are provided with limiting grooves 118 for lifting and lowering the lower limit wheel 116. The upper limit wheel 115 is installed on the top of the U-shaped frame 111, and the left protection wheel 113 and the right protection wheel 114 are respectively installed on the left and right sides of the outside of the U-shaped frame 111. The left protection wheel 113 and the right protection wheel 114 are mainly used to protect the cables and prevent them from rubbing against the U-shaped frame 111 and damaging the cables, while reducing friction. The upper limit wheel 115 is mainly used to compress the cables for protection and prevent them from lifting out of the equipment.

[0049] Further, in some embodiments of the present invention, Figure 5 As shown, the track drive mechanism 320 includes a motor 321, a reduction box 322, a driving sprocket 323, and a driven sprocket 324. The motor 321, the reduction box 322, and the driving sprocket 323 are connected in sequence. The driving sprocket 323 and the driven sprocket 324 are driven by the track. The power is provided by the motor 321 and transmitted to the driving sprocket 323, the driven sprocket 324 and the track 330 through the reduction box 322; the driven sprocket 324 is connected to a track tensioning device 600 to facilitate the adjustment of its tension and loosening.

[0050] like Fig. 9 As shown, in some embodiments of the present invention, the track tensioning device 600 includes a support plate 610, an adjusting screw 620, a first nut 630, and a second nut 640. The support plate 610 is fixed on the mounting bracket 310 and has a through hole. One end of the adjusting screw 620 is inserted into the through hole and the other end is against the driven sprocket 324. The mounting bracket 310 has a slide groove 311. The chain rod 3241 of the driven sprocket 324 is installed in the slide groove 311. The first nut 630 and the second nut 640 are both installed on the adjusting screw 620 and attached to both sides of the support plate 610. When in use, the adjusting screw 620 can be moved forward and backward by rotating the first nut 630 or the second nut 640 with a wrench, so as to drive the chain rod 3241 of the driven sprocket 324 to move in the slide groove 311, thereby tightening and loosening the track.
