[0002] Power engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes projects that apply electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation expansion projects. The distribution network is the network in power engineering that distributes electrical energy. The distribution network refers to the power grid that receives electrical energy from the transmission network or regional power plants and distributes it locally or in stages according to voltage to various users through distribution facilities. It consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities.

[0003] In existing cable laying methods, workers are generally the main force, and they lay cables by manually dragging them. However, different power grids use different cable specifications, and some cables are relatively large, making manual dragging difficult and strenuous. In addition, some construction sites are in poor condition, which also increases the difficulty of dragging cables. Therefore, an auxiliary traction mechanism for power distribution networks was designed. Utility Model Content

[0020] like Figures 1 to 5 As shown, an auxiliary traction mechanism for power distribution network includes a mounting block 1. A caster wheel 5 is fixedly connected to the bottom of the mounting block 1. The caster wheel 5 allows the mounting block 1 to move relatively freely, improving the handling efficiency. A handle 21 is fixedly connected to the front end of the mounting block 1, which facilitates pushing the mounting block 1 to move.

[0021] A traction mechanism 2 is mounted on the mounting block 1. The traction mechanism 2 includes a slider 1 201, a slider 202, a transmission roller 203, a motor 204, a bidirectional threaded rod 205, a bracket 206, a mounting plate 207, a connecting block 13 208, a connecting rod 209, a hand crank 210, and a sliding assembly 211. A cavity 3 is provided on the mounting block 1, and two transmission rollers 203 are arranged vertically within the cavity 3. A slider 1 201 is mounted on one end of each transmission roller 203. The transmission roller 203 is rotatably connected to the first slider 201. A second slider 202 is mounted on the other end of the transmission roller 203. The transmission roller 203 and the second slider 202 are rotatably connected. Slide grooves 4 are provided on both sides of the mounting block 1, and the slide grooves 4 pass through the cavity 3. The first slider 201 slides in the right slide groove 4, and the second slider 202 slides in the left slide groove 4. A connecting block 13208 is fixedly connected to the lower surface of the first slider 201, and a mounting plate 207 is fixedly connected to the lower surface of the connecting block 13208. The motor 204 is mounted on the mounting plate 207. The output of the motor 204 is fixedly connected to the transmission roller 203. The motor 204 is used to drive the transmission roller 203 to rotate. The two sliders 11 slide on the bidirectional screw rod, and the two sliders move relative to each other under the drive of the bidirectional screw rod 205. A bracket 206 is set at each end of the bidirectional screw rod 205. The bidirectional screw rod 205 is rotatably connected to the bracket 206, and the bracket 206 is fixedly connected to the mounting block 1. A connecting rod 209 is fixedly connected to the upper end of the bidirectional screw rod 205. A hand crank 210 is fixedly connected to the connecting rod 209. By cranking the hand crank 210, the rotation of the bidirectional screw rod 205 can be controlled. The sliders 11 drive the transmission roller 203 to move, thereby controlling the distance between the two transmission rollers 203, so that this device can adapt to different types of cables. A sliding component 211 is set on the front and rear sides of the transmission roller 203, and the sliding component 211 is mounted on slider 1 201 and slider 2 202.

[0022] A set of telescopic rods 6 is provided on the left and right sides of the mounting block 1. Each set of telescopic rods 6 consists of two rods, and each telescopic rod 6 is fixedly connected to the mounting block 1. A fixing rod 8 is fixedly connected between the two telescopic rods 6. A cylinder 9 is provided between the two telescopic rods 6. One end of the cylinder 9 is hinged to the fixing rod 8, and the other end of the cylinder 9 is hinged to the mounting block 1. A support block 7 is fixedly connected to the bottom of the telescopic rod 6, and a rubber pad 15 is fixedly connected to the support block 7. The telescopic rod 6 can be pushed out by the cylinder 9, and the entire mounting block 1 can be lifted by the support block 7 to make the caster wheel 5 leave the ground. This makes the cable more stable when being pulled, and the rubber pad 15 increases the friction with the ground.

[0023] A locking block 18 is provided on the mounting block 1. The locking block 18 is located between the top of the mounting block 1 and the upper end face of the bidirectional threaded rod. The locking block 18 is fixedly connected to the mounting block 1. A through hole 19 is provided on the locking block 18. The connecting rod 209 is located in the through hole 19. A through groove 20 is provided on the locking block 18. The through groove 20 passes through the through hole 19. Bolts and nuts are provided on the mounting block 1. The bolts and nuts are located at the through groove 20. The through groove 20 can be tightened by the bolts and nuts to fix the connecting rod 209. This prevents the connecting rod 209 from rotating and ensures that the bidirectional threaded rod 205 will not rotate during the traction process. A storage box 22 is fixedly connected to the mounting block 1. The storage box 22 is located below the handle 21 and is used to store tools for storing bolts and nuts.

[0024] The sliding assembly 211 includes a positioning rod 10, a slider 11, a clamping block 12, and a support rod. A support rod is provided on each side of the positioning rod 10. The support rod at the right end of the positioning rod 10 is fixedly connected to slider 11 201, and the support rod at the left end of the positioning rod 10 is fixedly connected to slider 202. The right support rod is attached to the right end of the positioning rod 10, and the left support rod is attached to the left end of the positioning rod 10. A protrusion 16 is provided at each end of the positioning rod 10. Mounting holes 17 that mate with the protrusions 16 are provided on the support rods. The protrusions 16 are square, which effectively prevents the positioning rod 10 from rotating. Slider 11 slides on the positioning rod 10, and the positioning rod 10... 0 is a square, which can prevent the slider 3 11 from rotating during the sliding process. A clamping block 12 is fixedly connected below the slider 3 11. One end of the clamping block 12 has an arc-shaped groove 14. During the cable pulling process, the cable may move back and forth from side to side. The transmission roller 203 alone cannot stabilize the cable well. However, by clamping the cable with the arc-shaped grooves 14 on the upper and lower clamping blocks 12, the stability of the cable can be increased. The positioning rod 10 will adjust together with the adjustment of the transmission roller 203. The same rubber pad 15 as on the support block 7 is fixedly connected in the arc-shaped groove 14. The rubber pad 15 can increase the friction of the clamping block 12 on the cable.

[0025] Working principle of the utility model: By loosening the bolts and nuts on the locking block 18, the hand crank 210 is rotated to adjust the position between the two transmission rollers 203 to accommodate cables of different sizes. While adjusting the transmission rollers, the slider 3 11 needs to be moved so that the clamping block 12 on the slider 3 11 can clamp the cable at the same time as the transmission roller 203. The clamping block 12 can increase the stability of the cable during the traction process, and if the cable moves left or right, the clamping block 12 can move with the cable. The motor 204 controls the transmission roller 203 to rotate for traction.
