Description

Technical Field

[0001] This utility model relates to the field of cable trench trolley technology, specifically a double-sided cable trench trolley. Background Technology

[0002] In cable trench construction, traditional cable trench trolleys rely on guide rails for movement. While this ensures basic positioning during construction, the cumbersome process of laying guide rails greatly restricts construction efficiency and flexibility.

[0003] Based on the above, the following problems were found: During the construction of the cable trench trolley, the guide rail is subjected to the pressure and friction generated by the trolley's operation for a long time, which can easily lead to wear, deformation, and displacement. Regular maintenance and repair are required. Once the guide rail malfunctions, such as local deformation causing the trolley to jam, construction must be stopped first, and the faulty section of the guide rail must be removed for replacement or correction. The whole process is time-consuming and labor-intensive, which seriously affects the construction progress.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a double-sided cable trench trolley in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a double-sided cable trench trolley to solve the problem mentioned in the background art that the cable trench trolley relies on guide rails for movement. Although this can ensure the basic positioning of the construction, the cumbersome process of laying the guide rails greatly restricts the construction efficiency and flexibility.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A double-sided cable trench trolley includes a main body, a moving mechanism, and a steering mechanism. The main body includes a cable trench trolley body, with a pair of movable slots at both ends. A sliding sleeve is installed at the bottom of each movable slot, and a moving block is slidably installed inside each sliding sleeve. The steering mechanism includes four steering boxes, the upper ends of which are rotatably fitted onto the bottom ends of the moving blocks. A steering wheel is rotatably connected to the bottom end of each steering box. The moving mechanism includes a pair of movable boxes, each located on both sides of the bottom end of the cable trench trolley body. Several driven wheels are rotatably connected to one side of the interior of each movable box, and a drive wheel is rotatably connected to the other side of the interior of each movable box.

[0008] Furthermore, a conical gear disk is fixedly installed at the bottom end of the moving block inside the steering box, and a conical gear is rotatably connected to one side of the steering box, with the conical gear meshing with the conical gear disk.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the bevel gear meshes with the bevel gear plate, converting the rotational power of the first hydraulic motor into the steering torque of the steering box, ensuring that the trolley can turn flexibly and position accurately.

[0010] Furthermore, a first reducer is fixedly installed on one side of the steering box, and the output end of the first reducer is connected to a bevel gear transmission.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the first reducer reduces the output speed of the first hydraulic motor and increases the torque, so that the bevel gear rotates smoothly, avoiding excessive impact on the steering box due to excessive speed during steering, and ensuring the stability and reliability of the trolley steering process.

[0012] Furthermore, a first hydraulic motor is fixedly installed on one side of the first reducer, and the output end of the first hydraulic motor is connected to the input end of the first reducer.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the first hydraulic motor provides power to the steering mechanism, and by utilizing the high efficiency and stability of hydraulic transmission, it drives the first reducer, bevel gear and bevel gear plate to work together to achieve continuous and precise steering of the steering box, and adapt to the steering needs of the trolley under different working conditions.

[0014] Furthermore, each of the movable slots has a support base fixedly installed at its upper interior, and each support base has a first hydraulic telescopic rod hinged to its bottom end. The output end of the first hydraulic telescopic rod is hinged to the top end of the movable block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the first hydraulic telescopic rod is hinged between the support base and the moving block. By controlling the extension and retraction of the first hydraulic telescopic rod, the cable trench trolley body can be raised as a whole, thereby adjusting the ground clearance of the drive wheel and the driven wheel, so that the drive wheel and the driven wheel can be adapted to travel on the track and also to travel on the ground.

[0016] Furthermore, a second reducer is fixedly installed on each of the opposing surfaces of the mobile box on one side of the drive wheel, and the output end of the second reducer is connected to the drive wheel via a transmission.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the second reducer reduces the output speed of the second servo motor and increases the torque, making the drive wheel rotate more smoothly, avoiding slippage of the trolley when starting or traveling due to excessive speed, and ensuring stable movement and uniform power output of the trolley during cable trench construction.

[0018] Furthermore, a second servo motor is fixedly installed at the upper end of the second reducer, and the output end of the second servo motor is connected to the input end of the second reducer.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the second servo motor provides power to the moving mechanism, and by controlling the speed and direction, it realizes the uniform or variable speed movement of the drive wheel, which, together with the driven wheel, enables the trolley to move smoothly.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The movable groove and sliding sleeve of the main body of this double-sided cable trench trolley provide a sliding track for the moving block. The support seat cooperates with the first hydraulic telescopic rod, allowing the cable trench trolley body to be raised as a whole when the steering wheel is supported by the ground, thereby adjusting the overall level of the cable trench trolley body. When the track is in normal working order, the steering wheel can be fitted onto the track for guidance, causing the driven wheel and drive wheel to engage with the track, thereby moving the cable trench trolley body. When the track is damaged and needs to be disassembled for repair, the steering wheel, in conjunction with the driven wheel and drive wheel, can directly... On the ground, the steering wheels can be adjusted in direction to ensure the accuracy of the cable trench trolley's movement. The first hydraulic motor of the steering mechanism drives the steering box to rotate around the moving block through the first reducer, bevel gear, and bevel gear disc, enabling the cable trench trolley to steer flexibly. The second servo motor of the moving mechanism drives the drive wheel through the second reducer, which, together with the driven wheel, enables the trolley to move smoothly. Even if the track is damaged and needs repair, the cable trench trolley can move on its own and adjust its position in real time according to the pouring requirements, improving pouring accuracy and avoiding downtime due to track repairs.

[0027] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-5This utility model provides a technical solution: a double-sided cable trench trolley, comprising a main body 1, a moving mechanism 2, and a steering mechanism 3. The main body 1 includes a cable trench trolley body 101, with a pair of movable slots 102 at both ends of the cable trench trolley body 101. A sliding sleeve 106 is installed at the bottom of each movable slot 102, and a moving block 105 is slidably installed inside each sliding sleeve 106. The steering mechanism 3 includes four steering boxes 301, the upper ends of which are rotatably fitted onto the bottom ends of the moving blocks 105. The bottom ends of each steering box 301... A steering wheel 304 is rotatably connected; the moving mechanism 2 includes a pair of moving boxes 201, which are respectively disposed on both sides of the bottom end of the cable trench trolley body 101. Several driven wheels 202 are rotatably connected to one side of the interior of each moving box 201, and a drive wheel 203 is rotatably connected to the other side of the interior of each moving box 201. The movable groove 102 and sliding sleeve 106 of the main body 1 provide a sliding track for the moving block 105. The support seat 103 cooperates with the first hydraulic telescopic rod 104, so that when the steering wheel 304 supports the ground, the entire cable trench trolley body 101 can be moved. The body rises, thereby adjusting the overall level of the cable trench trolley body 101. When the track is in normal working order, the steering wheel 304 can be fitted onto the track for guidance, allowing the driven wheel 202 and drive wheel 203 to engage with the track, thus moving the cable trench trolley body 101. When the track is damaged and needs disassembly and repair, the steering wheel 304, in conjunction with the driven wheel 202 and drive wheel 203, can move directly on the ground. The steering wheel 304 can be directionally adjusted to ensure the accuracy of the cable trench trolley body 101's movement; the first hydraulic motor 303 of the steering mechanism 3... The first reducer 302, bevel gear 305, and bevel gear disc 107 drive the steering box 301 to rotate around the moving block 105, enabling the cable trench trolley body 101 to steer flexibly. The second servo motor 205 of the moving mechanism 2 drives the drive wheel 203 via the second reducer 204, which, together with the driven wheel 202, enables the trolley to move smoothly. Even if the track is damaged and needs repair, the cable trench trolley body 101 can move on its own and adjust its position in real time according to the pouring requirements, thereby improving the pouring accuracy and avoiding downtime caused by track repairs.

[0030] Please see Figures 1-5A conical gear 107 is fixedly installed inside the steering box 301 at the bottom end of the movable block 105. A conical gear 305 is rotatably connected to one side of the steering box 301, meshing with the conical gear 107. A first reducer 302 is fixedly installed on one side of the steering box 301, with its output end connected to the conical gear 305. A first hydraulic motor 303 is fixedly installed on one side of the first reducer 302, with its output end connected to the input end of the first reducer 302. A support base 103 is fixedly installed at the upper end of the movable slot 102, with a first hydraulic telescopic rod 104 hinged to the bottom end of each support base 103. The output end of the first hydraulic telescopic rod 104 is hinged to the top end of the movable block 105. The conical gear 305 meshes with the conical gear 107, converting the rotational power of the first hydraulic motor 303 into the steering torque of the steering box 301, ensuring the trolley rotates... To ensure flexibility and accurate positioning, the first reducer 302 lowers the output speed of the first hydraulic motor 303 and increases the torque, making the bevel gear 305 rotate smoothly. This avoids excessive impact on the steering box 301 due to excessive speed during steering, ensuring the stability and reliability of the trolley's steering process. The first hydraulic motor 303 provides power to the steering mechanism 3. Utilizing the efficiency and stability of hydraulic transmission, it drives the first reducer 302, bevel gear 305, and bevel gear disc 107 to work together, achieving continuous and precise steering of the steering box 301. This adapts to the steering requirements of the trolley under different working conditions. The first hydraulic telescopic rod 104 is hinged between the support base 103 and the moving block 105. By controlling the extension and retraction of the first hydraulic telescopic rod 104, the cable trench trolley body 101 can be raised as a whole, thereby adjusting the ground clearance of the drive wheel 203 and driven wheel 202. This allows the drive wheel 203 and driven wheel 202 to adapt to both track and ground travel.

[0031] Please see Figures 1-5 A pair of moving boxes 201 are each fixedly mounted with a second reducer 204 on one side of the drive wheel 203. The output end of the second reducer 204 is connected to the drive wheel 203. A second servo motor 205 is fixedly mounted on the upper end of the second reducer 204. The output end of the second servo motor 205 is connected to the input end of the second reducer 204. The second reducer 204 reduces the output speed of the second servo motor 205 and increases the torque, so that the drive wheel 203 rotates more smoothly and avoids slippage of the trolley when starting or moving due to excessive speed. This ensures that the trolley moves stably and the power output is uniform during the cable trench construction process. The second servo motor 205 provides power to the moving mechanism 2. By controlling the speed and direction, the drive wheel 203 can be made to move at a constant speed or variable speed. This, together with the driven wheel 202, makes the trolley move smoothly.

[0032] Working principle

[0033] In use, under normal track conditions, the first hydraulic telescopic rod 104 operates, raising the cable trench trolley body 101 as a whole, causing the drive wheel 203 and driven wheel 202 to engage with the track. The second servo motor 205 outputs power, which, after being reduced in speed and increased in torque by the second reducer 204, drives the drive wheel 203 to rotate, cooperating with the driven wheel 202 to move the cable trench trolley body 101 along the track. The steering wheel 304, fitted onto the track, serves as a guide. When the track is damaged and requires repair, the first hydraulic telescopic rod 104 is controlled... 4. When working again, the cable trench trolley body 101 is lowered as a whole, so that the drive wheel 203 and driven wheel 202 contact the ground. When turning is required, the first hydraulic motor 303 is started, and the power is transmitted to the bevel gear 305 through the first reducer 302. By meshing with the bevel gear plate 107, the steering box 301 is driven to rotate around the moving block 105, so as to realize the direction adjustment of the steering wheel 304. At the same time, the second servo motor 205 continues to drive the drive wheel 203, which works with the driven wheel 202 to make the trolley move autonomously on the ground.

[0034] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
