[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1-2 As shown, it illustrates a specific embodiment of the present invention: as Figures 1-2 As shown, the present invention discloses an improved bypass cable laying vehicle, including a support plate 7, a pulley 5 at the bottom of the support plate 7, a bypass load switch at the top of the support plate 7, and several cable laying racks on the upper side of the support plate 7. The cable laying racks include support columns 4, first rollers 2, first fixed shafts and guard plates 1. Several support columns 4 are spaced apart on the upper side of the support plate 7. A first roller 2 is provided between every two adjacent support columns 4. Guard plates 1 are fixedly installed on the outer left and right sides of each first roller 2. A first fixed shaft is fixedly installed at both ends of each first roller 2. A first placement groove with an upward opening is provided at the upper end of the support column 4 corresponding to the position of each first fixed shaft. The first fixed shaft is located in the first placement groove and fixedly connected. A brake device 3 is provided at the bottom of the guard plate 1 near the outer side of the first roller 2.

[0027] Preferred, such as Figures 1-2 As shown, the braking device 3 is fixedly installed on the support plate 7; the support plate 7 is provided with a handle for movement.

[0028] A brake device 3 is provided at the bottom of the guard plate 1 near the outer side of the first roller 2. An adjustable brake device 3 is installed on the support plate. Since the cable storage has a certain weight, the support plate needs to be made of high-strength material. The pulley design facilitates on-site movement, and the handle design makes it even easier to move.

[0029] Preferred, such as Figure 2 As shown, the braking device 3 includes a base 205, a slider 204, a guide rail 202, a lead screw 203, a hand crank 201, a brake pad seat 206, and a brake pad 207. The base 205 is fixedly installed on the support plate 7. Two guide rails are connected to the two ends of the upper part of the base 205. The slider 204 slides through the guide rail 202. The middle part of the slider 204 is provided with a thread that cooperates with the lead screw 203. One end of the lead screw 203 passes through the side of the base 205 and is threadedly connected to the slider 204. A hand crank 201 is provided at the end of the lead screw 203 away from the slider 204. A brake pad seat 206 is provided on the upper side of the slider 204, and a brake pad 207 is fixed on the brake pad seat 206.

[0030] When using the cable, rotating the handwheel of the brake mechanism will cause the lead screw to push the slider inward, bringing the brake pads closer to the outer circumference of the first roller and thus applying the braking effect. When retracting the cable, rotating the handwheel of the brake mechanism will cause the lead screw to push the slider outward, moving the brake pads away from the outer circumference of the first roller and thus canceling the braking.

[0031] Preferred, such as Figure 1 As shown, the support plate 7 is provided with brackets 8 at both the left and right ends. Each bracket 8 includes a support rod, a second roller 6, and a second fixed shaft. The support plate 7 is provided with support rods at both the front and rear ends, and the second roller 6 is provided between the support rods. The second fixed shaft is fixedly installed at both the front and rear ends of the second roller 6. The upper end of the support rod corresponding to the second fixed shaft position is provided with a second placement groove with an upward opening. The second fixed shaft is located in the second placement groove and is fixedly connected. The support plate corresponding to the bottom of the second roller 6 is provided with a groove. The groove is provided with a water-absorbing sponge. The water-absorbing sponge fills the groove and is flush with the upper surface of the support plate 7.

[0032] During cable winding and unwinding operations, there is often dragging on the ground, which causes the cable surface to be contaminated by dust, dirt, oil and other pollutants. This makes the cable surface dirty and may even affect the insulation performance and service life of the cable. A groove is designed with water and an absorbent sponge inside. When the cable is winding and unwinding, it passes through the second roller and is wound onto the first roller. During the winding and unwinding process, the cable passes through the absorbent sponge, which can clean the cable surface and increase the cable's service life.

[0033] Preferred, such as Figure 1 As shown, the second roller 6 is an absorbent roller.

[0034] When the cable passes through the absorbent sponge, the cable surface can be cleaned. The cable surface will have a certain degree of humidity, and the moisture on the cable surface may seep into the cable insulation material, accelerating insulation aging and causing a decline in cable insulation performance. It should be cleaned and dried in time. The second roller is designed as an absorbent roller, which can wipe the cable during the cable winding and unwinding process to keep the cable surface dry.

[0035] Preferably, the braking device 3 is provided with a locking device; the support plate 7 is connected with a grounding wire, and one end of the grounding wire is provided with a grounding wire clamp; the upper end of each support column 4 is provided with an upward-opening first placement groove, the upper end of the support column 4 is provided with a mounting ear, and the upper part of the first placement groove is provided with a fastener that is bolted to the mounting ear.

[0036] The braking device 3 is equipped with a locking device to achieve the purpose of locking, which can obtain a large holding force and prevent the cable laying rack from moving freely when it is stopped; the upper end of the support column is provided with a mounting ear. After the mounting ear and fastener bolts are fixed, the connecting part forms a first placement groove, and the first fixed shaft is located in the first placement groove. This design can facilitate the replacement of the cable laying rack and increase the service life of the device.

[0037] Preferably, the locking device is a locking nut, and the slider 204 has a threaded hole on its side, and the locking nut is threadedly connected to the slider 204.

[0038] The brake device 3 is equipped with a locking device. The slider 204 has a threaded hole on its side. The locking nut can fix the guide rail to achieve the locking purpose and obtain a large holding force to further lock the brake device and prevent the cable laying rack from moving freely when it is stopped.

[0039] Preferably, the locking device is a locking nut, and a threaded hole is provided on the top of the end face of the upper part of the base 205 near the hand crank 201. The position of the threaded hole is perpendicular to the position where the lead screw 203 passes through, and the locking nut is threadedly connected to the base 205.

[0040] The brake device 3 is equipped with a locking device. A threaded hole is opened on the top of the end face of the base 205 near the hand crank 201. The locking nut can fix the screw rod to achieve the locking purpose and obtain a large holding force to further lock the brake device and prevent the cable laying rack from moving freely when it is stopped.

[0041] Preferably, a gearbox is provided at the first placement slot through which the first fixed shaft passes through the support column 4. The gearbox includes a herringbone gear on the first fixed shaft and a gear meshing with the herringbone gear. The gear is provided with a handwheel shaft, and a handwheel is provided at the position where the handwheel shaft extends to the outside of the gearbox.

[0042] By setting a handwheel, cable winding and unwinding can be made more convenient and faster. Operators only need to turn the handwheel to complete the winding and unwinding of the cable, reducing the time and labor intensity of manual operation.

[0043] Preferably, the top two sides of the support column 4 are provided with reinforcing frames at a 30-degree angle to the support column 4, and extend and are fixed to the support plate 7.

[0044] The cable laying rack and support plate need to bear the weight of the cable, so they need to have a large load-bearing capacity to avoid deformation or damage caused by excessive cable weight. Not only must the materials have sufficient strength and stability, but the weight should not be too large, otherwise it will reduce the convenience of operation. The structural design also considers the most stable structure. The triangular reinforcing frame has high strength and stability and can withstand greater pressure and tension, increasing the overall strength and stability of the device.

[0045] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
