Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a cable laying auxiliary device. Background Art

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. According to the application scenario, it can be divided into several laying methods, such as overhead, underground, underwater, wall and tunnel. Reasonable selection of cable laying method is very important to ensure the transmission quality, reliability and construction and maintenance of the line.

[0003] Traditionally, cable laying and pulling is often done by manual dragging, which is not only labor-intensive and inefficient, but also easily causes damage to the cable insulation layer.

[0004] The invention patent with announcement number CN212799050U is a kind of wire laying and pulling equipment, which includes a base plate, a connecting frame and a wire laying U-shaped frame; the outer surface of the base plate is fixedly connected to a connecting frame, and the number of the connecting frames is two; the two connecting frames are fixedly connected to a connecting plate at one end away from the base plate, and the outer surface of the connecting plate is provided with an installation groove, and the number of the installation grooves is two, and the interior of the two installation grooves is rotatably connected to a connecting support rod through a rotating shaft, a fixed shaft is fixedly connected between the two connecting support rods, and the outer surface of the fixed shaft is rotatably connected to a movable block.

[0005] The above-mentioned wire laying and pulling equipment can be easily moved. During the laying process, the cable extends from the middle position between the hollow casing and the guide wheel and enters under the wire pressing wheel. Under the action of the compression spring and the pressure rod, the wire pressing wheel presses the cable into the cable laying path to be laid, thus realizing the laying of the cable. However, the above-mentioned equipment is only convenient for laying buried cables in urban environments. When cables generally need to be overhead in outdoor high-voltage power transmission environments, since the height of high-voltage transmission towers is generally around tens of meters, and the span between two high-voltage transmission towers is often large due to factors such as terrain, the above-mentioned wire laying and pulling equipment does not have a structure for pulling and raising the cable, and cannot meet the needs of overhead cable laying.

[0006] In view of the above reasons, the present invention proposes a cable laying auxiliary device to overcome the above defects. Summary of the invention

[0007] The object of the present invention is to provide a cable laying auxiliary equipment, which can solve the problem that the background technology cannot meet the demand for overhead cable laying, facilitate the tensioning and overhead laying of cables, and meet the demand for overhead cable laying.

[0010] Preferably, a rotatable wire-pressing wheel is also provided on the surface of the lifting mounting seat. After the cable is led out from the cable reel, it bypasses the lower side of the wire-pressing wheel and extends to the guide wheel.

[0011] Preferably, the bottom of the lifting mount is connected to the vehicle body surface via a scissor mechanism or a plurality of hydraulic rods.

[0012] Preferably, the lifting rod is an electric lifting rod, a connecting rib is provided at the top end of the electric extending and lowering rod, the guide wheel is rotatably connected to the connecting rib, and the axis of the guide wheel is perpendicular to the axis of the electric lifting rod.

[0013] Preferably, the bottom of the lifting support seat is connected to the surface of the vehicle body through a scissor mechanism or a plurality of electric push rods.

[0016] Preferably, the top end of each telescopic support rod is hinged to the bottom of each section of the extension rod.

[0017] Preferably, the bottom end of the telescopic support rod is provided with a pointed portion capable of being inserted into the ground.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The height of the cable reel can be adjusted through the lifting mounting seat, so that it is more labor-saving when pulling the cable overhead. The cable reel can be guided by the guiding mechanism to further rise. The cable guided by the guide wheel of the guiding mechanism will pass around the guide wheels at the ends of each extension rod of the extension pulling mechanism in turn. Then, the extension rods of the extension pulling mechanism are controlled to extend in turn, so that the cable can be pulled out for convenient overhead laying, which can meet the needs of high-altitude laying.

[0020] 2. The cable can be pulled by multi-section extension rods, which can solve the problem of large span between adjacent high-voltage transmission towers when laying cables overhead in the field. The cable and extension rod can be weighed in sections through the supporting mechanism, avoiding excessive work intensity caused by relying solely on manpower pulling, and meeting the needs of overhead laying in the field.

One side of the mounting seat 2 extends horizontally, wherein one end of the extension rod 52 close to the lifting support seat 51 is hinged to the top of the lifting support seat 51, and the upper surface of the end of each extension rod 52 away from the lifting support seat 51 is provided with a mounting rod 53 and a guide wheel 54, and the support mechanism 6 includes a plurality of telescopic support rods 61, and the top of each telescopic support rod 61 is rotatably connected to the lower side of the end of each extension rod 62 away from the lifting support seat 51. The cable 7 is untied from the cable reel 3 as the cable reel 3 rotates, and is guided and raised in height by the guide mechanism 4, and then bypasses the guide wheels 54 and extends out as the extension rods 52 are pulled out. Compared with the laying method of cables purely relying on manpower to pull, the labor intensity is significantly reduced.

[0029] Specifically, a reel support 8 is provided on the surface of the lifting mounting seat 2, and the reel support 8 includes two support plates arranged relatively to the surface of the lifting mounting seat 2, and both ends of the core shaft of the cable reel 3 are rotatably connected to the support plates. One end of the core shaft of the cable reel 3 is installed with a driving motor 9 and a reducer that can drive it to rotate, and the driving motor 9 and the reducer are fixedly installed on the side of the reel support 8.

[0030] In this embodiment, a rotatable crimping wheel 10 is also provided on the surface of the lifting mounting seat 2. After the cable 7 is guided out from the cable reel 3, it passes by the lower side of the crimping wheel 10 and extends to the guide wheel 42. The tension of the cable 7 can be increased by the crimping wheel 10.

[0031] In this embodiment, the bottom of the lifting mount 2 is connected to the surface of the vehicle body 1 through a scissor mechanism 21, and the scissor mechanism 21 is hydraulically driven. In other embodiments, multiple hydraulic rods or electric push rods can also be used to achieve the lifting of the lifting mount 2.

[0032] In this embodiment, the lifting rod 41 is an electric lifting rod, and a connecting rib 43 is provided at the top of the electric extending and lowering rod. The guide wheel 42 is rotatably connected to the connecting rib 43, and the axis of the guide wheel 42 is perpendicular to the axis of the electric lifting rod.

[0033] In this embodiment, the bottom of the lifting support seat 51 is connected to the surface of the vehicle body 1 through a scissor mechanism. In other embodiments, multiple electric push rods can also be used to connect to the surface of the vehicle body 1. The surface of the lifting support seat 51 is provided with a limiting arc groove that matches the outer periphery of the extension rod 52 close to it. When the outer periphery of the extension rod 52 matches the limiting arc groove, the axis of the extension rod 52 is parallel to the surface of the vehicle body 1. The extension rod 52 can be set to be electric and can be automatically controlled to extend and retract through a remote control.

After use, the telescopic support rod 61 is shortened, and then the extension rod 52 is retracted, so that the telescopic support rod 61 is shortened and rotated to be stored on the vehicle body 1.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
