Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable laying technology, and in particular to an auxiliary laying tool used in cable laying. Background Technology
[0002] Early cables used natural insulating materials such as cotton, linen, and rubber, which had poor durability and were easily affected by the environment. Introduced in 1893, high-voltage cables became the mainstream due to their excellent electrical properties, but they suffered from problems such as poor resistance to moisture and limitations in drop height. In the mid-20th century, they became the mainstream for low-voltage cables, offering lower cost but with limited temperature resistance (≤70℃).
[0003] When using cables, a lifting platform is typically used for installation. However, in limited spaces, manual labor is often necessary. This method is time-consuming, labor-intensive, and poses significant safety hazards. In terms of safety, manual labor directly threatens both the operators and the cables themselves. From a health perspective, prolonged lifting of heavy objects can easily lead to occupational diseases such as lumbar disc herniation and rotator cuff injuries, with 70% of these cases directly related to manual labor. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the existing method of manually moving and laying cables is time-consuming and labor-intensive, and also poses significant safety hazards.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary cable laying tool, comprising a trolley, an auxiliary lifting assembly connected to the top of the trolley, the auxiliary lifting assembly comprising two sets of fixed brackets, a support frame fixedly connected to the top of the two sets of fixed brackets, a reinforcing rib connected to the front end of the fixed brackets, a rotating rod inserted inside the support frame, one end of the rotating rod connected to the output end of a servo motor, a first helical gear connected to both sides of the rotating rod, a one-way screw inserted inside the fixed bracket, a second helical gear connected to the top of the one-way screw, a lifting frame connected to the surfaces of the two sets of one-way screws, threaded holes opened inside both sides of the lifting frame, and a hanging bracket connected to both sides of the front end of the threaded holes.
[0006] Furthermore, an uphill plate is rotatably connected to the front surface of the trolley, and a magnet is connected to the surface of the trolley near the uphill plate.
[0007] Furthermore, the magnet and the ramp are magnetically connected, and the servo motor is electrically connected to an external power source via a control switch.
[0008] Furthermore, the position and size of the first helical gear match the position and size of the second helical gear, and the first helical gear and the second helical gear form a meshing connection.
[0009] Furthermore, the one-way screw is threadedly connected to the lifting frame through a threaded hole, and the rotating rod is rotatably connected to the two sets of bearing seats.
[0010] Furthermore, the surface of the hanging bracket is provided with grooves, and omnidirectional wheels are connected to the four corners of the bottom of the trolley.
[0011] Furthermore, the rear end of the trolley is connected to a height adjustment assembly, which includes a fixed push handle, and the surface of the fixed push handle is connected to two sets of sleeves.
[0012] Furthermore, a hand-tightening bolt is inserted inside the sleeve, and a lifting handle is inserted inside the fixed push handle. Threaded grooves are equally spaced on the surface of the lifting handle.
[0013] Furthermore, the outer surface of the lifting handle is in contact with the inner wall of the fixed push handle, and the hand-tightening bolt passes through the fixed push handle and forms a threaded connection with the threaded groove.
[0014] Furthermore, the lifting handle is U-shaped, and a sliding connection is formed between the lifting handle and the fixed push handle.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, when the installation space is small and a lifting vehicle cannot be used for cable installation, the cable can be rolled onto a trolley via an incline. Then, a servo motor is activated to drive a rotating rod, causing two sets of one-way screws to rotate simultaneously. This screw rotation then lifts the cable, pushing the trolley to the target placement frame. After adjusting the cable position to precisely align with the frame, the servo motor is switched to forward rotation mode. The forward meshing transmission causes the one-way screws to smoothly lower the hanging frame until the cable is fully in contact with the placement frame, completing the installation. This eliminates the need for manual handling, reducing labor intensity and improving operational safety and installation efficiency.
[0017] 2. In this utility model, when operators of different heights push the trolley, they can turn the hand-tightening bolt to remove it from the threaded groove at the current position, and then adjust the height of the lifting handle and fix it, which is convenient for pushing and transporting and improves the flexibility of use.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] Example 1, such as Figure 1 - Figure 4As shown, this utility model provides an auxiliary cable laying tool, including a trolley 1. An auxiliary lifting assembly 2 is connected to the top of the trolley 1. The auxiliary lifting assembly 2 includes two sets of fixed supports 201. A support frame 202 is fixedly connected to the top of the two sets of fixed supports 201. A reinforcing rib 203 is connected to the front end of the fixed supports 201. A rotating rod 206 is inserted inside the support frame 202. One end of the rotating rod 206 is connected to the output end of a servo motor 205. First helical gears 207 are connected to both sides of the rotating rod 206. A one-way screw 209 is inserted inside the fixed supports 201. A second helical gear 208 is connected to the top of the one-way screw 209. A lifting frame 210 is connected to the surfaces of the two sets of one-way screws 209. A lifting frame 210 is opened on both sides of the lifting frame 210. The threaded hole 211 has a hanging bracket 212 connected to both sides of its front end. The front surface of the trolley 1 is rotatably connected to an uphill plate 214. A magnet 215 is connected to the surface of the trolley 1 near the uphill plate 214, and the magnet 215 and the uphill plate 214 form a magnetic attraction connection. The servo motor 205 is electrically connected to an external power supply through a control switch. The position and size of the first helical gear 207 match the position and size of the second helical gear 208, and the first helical gear 207 and the second helical gear 208 form a meshing connection. The one-way screw 209 is threadedly connected to the lifting frame 210 through the threaded hole 211. The rotating rod 206 is rotatably connected to the two sets of bearing seats 204. The hanging bracket 212 has a groove 213 on its surface. The trolley 1 has universal wheels connected to the four corners of its bottom.
[0027] The effect achieved in Embodiment 1 is that, during cable laying operations, the ramp 214 is first rotated and unfolded, and then the cable is smoothly rolled along the ramp 214 to the bearing surface of the trolley 1. The pre-installed connecting rods on both sides of the cable are precisely aligned with the grooves 213 on the top of the two sets of hangers 212. The reverse function of the servo motor 205 is activated, and its output power drives the two sets of first helical gears 207 to rotate in opposite directions through the rotating rod 206. The two sets of first helical gears 207 then form a reverse transmission with the two sets of second helical gears 208 that are vertically meshed, thereby driving the two sets of... The one-way screw 209 rotates synchronously in reverse; the one-way screw 209 engages with the lifting frame 210 on both sides through the threaded hole 211, driving the lifting frame 210 to rise at a constant speed, and lifting the cable connecting rod to the preset height through the groove 213 of the bracket 212; the trolley 1 is pushed to the target placement frame, the cable position is adjusted to precisely align with the placement frame, and the servo motor 205 is switched to forward rotation mode. Through forward meshing transmission, the one-way screw 209 drives the bracket 212 to descend smoothly until the cable is in complete contact with the placement frame, thus completing the installation. The entire process requires no manual handling, significantly reducing labor intensity, while mechanical linkage ensures operational safety and installation efficiency.
[0028] Example 2, as Figure 1 and Figure 5 As shown, the rear end of the trolley 1 is connected to a height adjustment assembly 3. The height adjustment assembly 3 includes a fixed push handle 301. Two sets of sleeves 302 are connected to the surface of the fixed push handle 301. A hand-tightening bolt 303 is inserted into the inside of the sleeve 302. A lifting handle 304 is inserted into the inside of the fixed push handle 301. Threaded grooves 305 are equidistantly opened on the surface of the lifting handle 304. The outer surface of the lifting handle 304 fits against the inner wall of the fixed push handle 301. The hand-tightening bolt 303 passes through the fixed push handle 301 and forms a threaded connection with the threaded groove 305. The lifting handle 304 is U-shaped and forms a sliding connection with the fixed push handle 301.
[0029] The effect achieved in Embodiment 2 is that when operators of different heights push the trolley 1, they can reverse the hand-tightening bolt 303 so that the front end of the hand-tightening bolt 303 can be removed from the threaded groove 305 at the current position. After removing both sets of hand-tightening bolts 303, the height of the lifting handle 304 is then adjusted. When adjusted to a suitable position, the hand-tightening bolt 303 is rotated forward so that the front end of the hand-tightening bolt 303 can enter the threaded hole 211 after adjustment for thread fixing. This facilitates pushing and improves the flexibility of use.
[0030] Working Principle: When the installation space is small and a lifting vehicle cannot be used for cable installation, the cable can be rolled onto the trolley 1 via the ramp 214. Then, the servo motor 205 is turned on to drive the rotating rod 206 to rotate, thereby causing the two sets of one-way screws 209 to rotate simultaneously. This screw rotation drives the cable upward, pushing the trolley 1 to the target placement frame. After adjusting the cable position to precisely align with the placement frame, the servo motor 205 is switched to forward rotation mode. Through forward meshing transmission, the one-way screws 209 drive the hanging frame 212 to descend smoothly until the cable is in complete contact with the placement frame, completing the installation. No manual handling is required, reducing labor intensity and improving operational safety and installation efficiency. When operators of different heights push the trolley 1, they can turn the hand-tightening bolt 303 to remove it from the threaded groove 305 at the current position, then adjust and fix the height of the lifting handle 304, facilitating pushing and improving flexibility during use.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
