Description

Technical Field

[0001] This application relates to the field of cable laying device technology, and in particular to an automatic cable counting and laying device. Background Technology

[0002] With the construction of new power systems, the application scope of high-voltage cables will continue to expand, and the volume of related engineering projects will inevitably continue to grow. However, during the laying process of high-voltage cables, there are construction challenges such as the large weight of the cable reel, the inflexible rotation of the reel hub, and difficulties in braking.

[0003] Currently, high-voltage cable laying frames are generally assembled on-site using laying frames, central bearings, and hydraulic jacks. While this can improve the stability of cable laying, the laying length of the cable can only be calculated by subtracting the beginning and end markings on the cable, which cannot accurately measure the actual laying length. Moreover, the laying frame needs to be dragged manually during laying, which increases labor costs. Utility Model Content

[0004] To address the problem that existing cable laying devices cannot accurately calculate the length of the cable laid out, this application provides an automatic cable counting and laying device.

[0005] The automatic cable counting and cable laying device provided in this application adopts the following technical solution:

[0006] An automatic cable counting and cable laying device includes: a cable laying frame, and further includes:

[0007] A traction trolley, wherein the wire feeding frame is mounted on the traction trolley, and the traction trolley is provided with at least one set of drive wheels and a power motor for driving the drive wheels to rotate;

[0008] A laser rangefinder, mounted on one side of the traction trolley, is used for distance measurement after the cable is taut; and

[0009] Cable tension testing equipment is used to test the tension of cables.

[0010] Furthermore, the cable tension detection mechanism includes:

[0011] A light source emitter, mounted on the traction trolley, is used to emit visible light horizontally;

[0012] A picture board, used to be mounted on a cable.

[0013] Furthermore, the upper end of the display panel is equipped with a hook for hanging onto a cable, and the lower end is equipped with a counterweight.

[0014] Furthermore, the surface of the display panel is provided with multiple concentric circular etched lines.

[0015] Furthermore, the light source emitter is equipped with a dust cover.

[0016] Furthermore, the traction trolley is equipped with a housing for covering the cable feeding frame, and the housing has a through hole for the cable to pass through, with the laser rangefinder located directly below the through hole.

[0017] Furthermore, the light source emitter is mounted on the housing and located between the perforation and the laser rangefinder.

[0018] Furthermore, the housing is equipped with a control panel for controlling the forward and reverse rotation of the power motor and the start and stop of the laser rangefinder and the light source emitter.

[0019] Furthermore, the traction trolley is equipped with a power supply for powering the drive motor, the laser rangefinder, the light source emitter, and the control panel.

[0020] Furthermore, the traction trolley is equipped with multiple ground anchors, at least one of which is located on the side of the traction trolley away from the laser rangefinder.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When laying cables, the cable reel can be installed on the laying frame, the power motor can be started to make the traction trolley move in the laying direction, and the cable can be laid out synchronously through the laying frame. No construction personnel are required to assist, which can greatly save manpower; and during the laying process, the distance can be measured by a laser rangefinder, which can measure the laying length of the cable.

[0023] 2. Before measurement, hang the display board on the extended cable using a hook, and start the light source emitter to emit visible light in the direction of cable extension. The emitted visible light falls on the display board to form a light spot. Use the concentric circle markings on the display board to locate the position of the light spot. When the light spot is at the center of the concentric circle markings, it means that the extended cable is taut. At this time, the cable length detected by the laser rangefinder is the most accurate and the error is the smallest.

[0024] 3. The tractor is powered by a power source composed of high-capacity rechargeable and discharging batteries, and there are no pollution emissions throughout the entire process. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] Reference Figure 1 and Figure 2 This application discloses an automatic cable counting and cable laying device, which includes a cable laying frame 1 and further includes:

[0040] The traction trolley 2 and the wire feeding frame 1 are mounted on the traction trolley 2. The traction trolley 2 is equipped with at least one set of drive wheels 21 and a power motor for driving the drive wheels 21 to rotate. The power motor is a servo motor, which can drive the two coaxial drive wheels 21 to rotate in both directions to realize the forward and backward movement of the traction trolley 2.

[0041] Laser rangefinder 3 is installed on one side of the traction trolley 2 and is used to measure the distance after the cable is taut.

[0042] Cable tension testing equipment is used to test the tension of cables.

[0043] Specifically, cable tension testing organizations include:

[0044] The light source emitter 41 is mounted on the traction trolley 2 and is used to emit visible light horizontally; the light source emitter 41 is covered with a dust cover made of transparent plastic.

[0045] The display board 42 is used to hang on the cable. Multiple concentric circular engravings 421 are provided on the surface of the display board 42. The upper end of the display board 42 is equipped with a hook 43 for hanging on the cable, and the lower end is equipped with a counterweight 44, which can be a weight.

[0046] Therefore, when laying out cables, the cable reel can be installed on the laying-out frame 1, the power motor can be started to make the traction trolley 2 move in the laying direction, and the cable can be synchronously unwound through the laying-out frame 1. No construction personnel are required to assist, which can greatly save manpower. In addition, during the laying process, the distance can be measured by the laser rangefinder 3 to measure the length of the cable. Before measurement, the display board 42 can be hung on the laid-out cable by the hook 43, and the light source emitter 41 can be started to emit visible light in the direction of cable extension. The emitted visible light falls on the display board 42 to form a light spot. The position of the light spot is located by the concentric circle engraving line 421 on the display board 42. When the light spot is at the center of the concentric circle engraving line 421, it means that the laid-out cable is in a taut state. At this time, the cable length detected by the laser rangefinder 3 is the most accurate and the error is the smallest.

[0047] In addition, to ensure that the traction trolley 2 does not move when the laser rangefinder 3 is detecting the cable length, refer to Figure 3 Multiple ground anchors 8 are inserted on the traction trolley 2, and at least one ground anchor 8 is located on the side of the traction trolley 2 away from the laser rangefinder 3.

[0048] Therefore, before the laser rangefinder 3 performs the measurement, the ground anchor 8 can be inserted into the soil to fix the traction trolley 2, which can ensure the safety of the trolley during the final measurement.

[0049] In addition, refer to Figure 1 and Figure 2 The traction trolley 2 is equipped with a housing 5 for covering the cable laying frame 1. The housing 5 has a through hole 51 for the cable to pass through. If necessary, a guide tube can also be set at the through hole 51 to reduce the wear of the cable when it passes through the through hole 51. The laser rangefinder 3 is located directly below the through hole 51. The light source emitter 41 is installed on the housing 5 and located between the through hole 51 and the laser rangefinder 3.

[0050] Therefore, the outer casing 5 can be used to shield and protect the unwound cable on the unwound frame 1, and guide it through the perforation 51; and by placing the laser rangefinder 3 and the light source emitter 41 directly below the perforation 51, the laser emitted by the laser rangefinder 3 and the visible light emitted by the light source emitter 41 can be coplanar with the unwound cable, thereby ensuring detection accuracy.

[0051] Furthermore, the outer casing 5 is equipped with a control panel 6 for controlling the forward and reverse rotation of the power motor and the start and stop of the laser rangefinder 3 and the light source emitter 41. The traction trolley 2 is equipped with a power supply 7 for supplying power to the power motor, laser rangefinder 3, light source emitter 41 and control panel 6. The power supply 7 is composed of a high-capacity rechargeable battery.

[0052] The implementation principle of the automatic cable counting and cable laying device in this application embodiment is as follows:

[0053] When laying out cables, the cable reel can be mounted on the laying-out frame 1. The power motor is started to make the traction trolley 2 move in the laying direction, and the cable is synchronously unwound through the laying-out frame 1. No construction personnel are required to assist, which can greatly save manpower. In addition, during the laying process, the distance can be measured by the laser rangefinder 3 to measure the length of the cable. Before measurement, the display board 42 can be hung on the laid-out cable by the hook 43. The light source emitter 41 is started to emit visible light in the direction of cable extension. The emitted visible light falls on the display board 42 to form a light spot. The position of the light spot is located by the concentric circle engraving line 421 on the display board 42. When the light spot is at the center of the concentric circle engraving line 421, it means that the laid-out cable is in a taut state. At this time, the cable length detected by the laser rangefinder 3 is the most accurate and the error is the smallest.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
