Description

Technical Field

[0001] The utility model belongs to the field of tension machines, and more specifically, relates to a wire bundling mechanism for a tension wheel. Background Art

[0002] A tension machine is a wire laying device used for tension stringing of transmission lines and erection of aerial ropeways. When a wire is pulled by an external force, it drives two roller wheels to rotate. By installing a braking mechanism on the roller wheels, the wire can be evenly stressed during the wire laying process, effectively avoiding the wire from sagging and rubbing against the ground or branches. During the operation of this device, not only does the tension wheel release the wire at a constant speed, but also the outer skin of the wire is protected.

[0003] When using a tension machine, the function of tension adjustment for the wire of a cable and the matching tension wheel is achieved through a plurality of guide wheels.

[0004] Chinese Patent with the authorization announcement number CN206624501U discloses a tension machine that can stabilize the traveling wheels at the bottom of the support seat when the tension machine is traction wire laying. A clamping block is hinged on the support seat of the utility model. When the tension machine is being transported, the clamping block is horizontally located on the support seat, and the clamping block has no influence on the transportation of the tension machine on the support seat. When the tension machine is performing traction wire laying, the support seat is supported by the traveling wheels. At this time, the hinged clamping block is pulled downwards, and the clamping block locks and holds the traveling wheels. In this way, the traveling wheels completely act as the role of support rods, and such a support seat can stably perform traction wire laying work.

[0005] The above technical solutions have the following defects:

[0006] Similar to traditional tension machines on the market, during use, the cable will be adjusted left and right according to its position around the tension wheel. The fixed guide wheel is often located in the middle of the tension wheel. When the tension changes or is adjusted, the inclined cable will shift (i.e., side slip) at this time, and the stability during the tension adjustment process cannot be guaranteed. At the same time, the function of adjusting the tension through the guide wheel is also lacking. Summary of the Utility Model

[0007] In view of the above defects, the utility model provides a wire bundling mechanism for a tension wheel, which includes a tension wheel installed on the side of the tension machine, and also includes a wire bundling member installed on the top of the tension machine. The wire bundling member includes a support frame fixed to the upper surface of the tension machine by bolts. The top end of the support frame is fixed with a suspended frame plate. An electric slide rail is installed on the top of the suspended frame plate. A matching electric slide block is installed at the electric slide rail. An adjusting mechanism for adjusting the tension of the cable is installed on the top of the electric slide block;

[0008] The adjusting mechanism includes a guide roller I and a guide roller II, which are respectively sleeved on the outside of the rotating shaft I and the rotating shaft II. The left and right ends of the rotating shaft I are respectively fixed to the top of the electric slider through telescopic rods. The telescopic rod on the right side is hinged with a connecting rod through a damping shaft, and the end of the connecting rod away from the guide roller I is fixedly connected to the right end of the rotating shaft II.

[0009] Furthermore, the working surfaces of the guide rollers I and II are concave surfaces, and the side walls of the concave surfaces are provided with a plurality of limiting beads.

[0010] Through the above technical solution, the guide wheels arranged on both sides can be removed, and the contacting cables can be guided by the rotatable limiting beads to reduce the wear of the outer surface of the cables.

[0011] Furthermore, an auxiliary guide wheel is installed in the middle of the front side of the suspended frame plate.

[0012] Through the above technical solution, it is ensured that the cable is always in the middle of the tension wheel during the transmission process.

[0013] Furthermore, the telescopic rod is height-adjustable via a V-shaped spring piece.

[0014] Through the above technical solution, the distance between the tension wheel and the adjustment mechanism can be adjusted to achieve the function of changing the tension. At the same time, it can also be retracted and reset to reduce the height for subsequent storage.

[0015] Furthermore, the length of the electric slide rail is greater than the width of the tension wheel.

[0016] The above technical solution can prevent the electric slider from driving the cable to separate from the working surface of the tension wheel.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The overall tension strength can be changed by changing the height between the adjustment mechanism and the tension wheel and changing the position of the guide roller II outside the guide roller I;

[0019] 2. Real-time adaptation of the cable position of the tension wheel winding can reduce the phenomenon of cable side slip during the tension adjustment process, ensure that the cable is always in the same position when output, and thus ensure the stability of the overall operation.

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings provide embodiments of the device. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example

[0027] like Figures 1-3 As shown, this embodiment provides a wire harness mechanism of a tension wheel, including a tension wheel 2 installed on the side of the tension machine 1, and also including a wire harness component 3 installed on the top of the tension machine 1, the wire harness component 3 includes a support frame 31 fixed to the upper surface of the tension machine 1 by bolts, and a suspended frame plate 32 is fixed to the top of the support frame 31. An auxiliary guide wheel 35 for keeping the cable always in the center position for transportation is installed in the middle of the front of the suspended frame plate 32. Its function is to ensure that the cable is always in the middle of the tension wheel during transmission, that is, in a unified output position, to ensure the stability of cable transportation. An electric slide rail 33 is installed on the top of the suspended frame 32. The length of the electric slide rail 33 is greater than the width of the tension wheel 2, which can ensure that the cable can always be at the top of the tension wheel 2 (i.e., the same vertical position) following the adjustment of the electric slider 34 and the electric slide rail 33 during transportation, and prevent the electric slider 34 from driving the cable off the working surface of the tension wheel 2 (i.e., the length of the electric slide rail 33 is less than the width of the tension wheel 2). A matching electric slider 34 is installed at the electric slide rail 33, and an adjustment mechanism 36 for adjusting the cable tension is installed on the top of the electric slider 34;

[0028] The adjusting mechanism 36 includes a guide roller I 363 and a guide roller II 364. The working surfaces of the guide roller I 363 and the guide roller II 364 are concave surfaces. A number of limiting beads 365 are provided on the side walls of the concave surfaces. It should be noted that a rubber ring is sleeved on the concave surface to prevent the contact surface of the cable from being worn and slipping. At the same time, the limiting beads 365 are steel balls located inside the spherical grooves opened on the side walls of the concave surfaces. The diameter value of the opening end of the spherical groove is smaller than the diameter value of the limiting beads 365, which can ensure that the limiting beads 365 are always inside the spherical grooves and will not affect their rotation, and can guide the cable when it moves to the side walls of the concave surfaces.

[0029] The guide roller I 363 and the guide roller II 364 are respectively sleeved outside the rotating shaft I 366 and the rotating shaft II 369. The left and right ends of the rotating shaft I 366 are respectively fixed to the top of the electric slider 34 through the telescopic rod 361. It should be noted that the height of the telescopic rod 361 is adjusted through the V-shaped elastic piece 362 (the V-shaped elastic piece 362 is the spring column used on the traditional umbrella handle and is adapted to the card slot provided at the telescopic rod 361 to achieve height limitation). The telescopic rod 361 on the right side is hinged with a connecting rod 368 through a damping rotating shaft 367. One end of the connecting rod 368 away from the guide roller I 363 is fixedly connected to the right end of the rotating shaft II 369.

[0030] When in use, the electric slider 34 is synchronously connected to the power supply of the motor inside the tensioning machine 1, and the position of the electric slider 34 is adjusted according to the winding position of the cable on the tensioning wheel 2 (maintaining directly above the cable output end). The cable winds from the tensioning wheel 2 to between the guide roller I 363 and the guide roller II 364. By rotating the connecting rod 368, the angle between the guide roller II 364 and the guide roller I 363 is adjusted to achieve contact with both ends of the cable therebetween, and then the tension adjustment process can be completed. Finally, it is output after being guided by the auxiliary guide wheel 35.

[0031] It should be noted that the structure of the present utility model can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other items, is included in the protection scope of the present utility model.
