Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, and in particular relates to a gantry crane type cable trough trolley. Background Technology

[0002] In infrastructure construction such as railways, highways, and municipal engineering, drainage ditches and cable troughs are key structures for ensuring smooth drainage and safe cable laying. They are typically laid along roadbeds, tunnels, or both sides of roads and require concrete pouring using formwork. The gantry crane-type drainage ditch and cable trough trolley, as a specialized piece of equipment for hoisting, moving, and pouring formwork for drainage ditch and cable troughs, has become a core piece of equipment for large-scale drainage ditch and cable trough construction due to its advantages of being able to move along the construction line and simultaneously complete multiple formwork operations.

[0003] The mainstream gantry crane cable trough trolleys on the market today generally rely on the traditional structure design of "electric hoist + steel wire rope" for their formwork lifting system. This lifting method lacks a guiding and positioning mechanism, which makes the formwork prone to swaying during lifting and lowering. When the formwork sways during lowering, it is necessary to manually adjust its position repeatedly to lower it to a suitable position inside the trench, which prolongs the construction time. In addition, the formwork may also collide with the wall during swaying, which can damage the formwork. Utility Model Content

[0004] In view of the technical problems existing in the background art, this utility model provides a gantry-type cable trough trolley.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A gantry crane-type cable trough trolley for water trenches includes a trolley body, a moving mechanism, and a guiding mechanism, wherein the moving mechanism drives the guiding mechanism to move laterally. The guiding mechanism includes a truss, the top of which is fixedly connected to the moving mechanism. A hanger is slidably inserted at the bottom of the truss, and several hooks are rotatably connected to the bottom of the hanger. Several first hydraulic telescopic rods are inserted at the top of the hanger, and a stop block is fitted at the output end of each first hydraulic telescopic rod. Laser positioners are embedded at both ends of the hanger. A pair of second hydraulic telescopic rods are inserted on the truss, and the output ends of the second hydraulic telescopic rods are fixedly connected to the top of the hanger.

[0006] Optionally, the moving mechanism includes a pair of first guide rails, the top ends of which are fixedly connected to the trolley body, a second guide rail is slidably sleeved on the bottom end of the first guide rails, a third guide rail is fixedly installed on the bottom end of each of the second guide rails, and a moving frame is slidably sleeved on the bottom end of the third guide rails, and the moving frame is fixedly connected to the truss.

[0007] Optionally, several first rollers are rotatably connected to both sides of the bottom end of the first guide rail, and the first rollers are in rolling connection with the top ends of both sides inside the second guide rail.

[0008] Optionally, a rotating shaft is rotatably inserted at the center of the first guide rail, and gears are fitted at both ends of the rotating shaft. Racks are provided on both sides of the top of the second guide rail, and the racks and gears mesh with each other.

[0009] Optionally, a speed reducer is fixedly connected to one side of the first guide rail, the output shaft of the speed reducer is driven by the rotating shaft, and a first drive motor is fixedly connected to the bottom of the speed reducer, the output end of the first drive motor is driven by the input end of the speed reducer.

[0010] Optionally, a pair of second rollers are rotatably connected to both sides of the inner top of the movable frame, and the second rollers are rollingly connected to the inner bottom of the third guide rail.

[0011] Optionally, a second drive motor is fixedly connected to both sides of the mobile frame, and the output end of the second drive motor is connected to a second roller at the corresponding position.

[0012] This utility model has the following advantages and beneficial effects: This truss-type cable trough trolley features a moving mechanism with first, second, and third guide rails and a moving frame that work together to achieve multi-directional extension, retraction, and sliding. This allows the guiding mechanism to flexibly adjust its position, adapting to the cable trough lifting needs of different construction scenarios. The truss and hanger of the guiding mechanism provide installation support for the hooks, which can stably suspend the cable trough. The first hydraulic telescopic rod pushes the stop block to press firmly against the top of the hoisting template, preventing swaying during lifting. The laser positioner emits a positioning laser to accurately calibrate the cable trough installation position, avoiding deviation. Overall, this system enables flexible lifting and precise positioning installation of the cable trough, improving construction efficiency and quality. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Example like Figures 1-5 As shown, a gantry crane cable trough trolley includes a trolley body 1, a moving mechanism 2 and a guiding mechanism 3, wherein the moving mechanism 2 drives the guiding mechanism 3 to move laterally. The guiding mechanism 3 includes a truss 301. The top end of the truss 301 is fixedly connected to the moving mechanism 2. A hanger 302 is slidably inserted into the bottom end of the truss 301. Several hooks 303 are rotatably connected to the bottom end of the hanger 302. Several first hydraulic telescopic rods 306 are inserted into the top end of the hanger 302. A stop block 307 is sleeved on the output end of the first hydraulic telescopic rod 306. Laser positioners 304 are embedded in both ends of the hanger 302. A pair of second hydraulic telescopic rods 305 are inserted into the truss 301. The output end of the second hydraulic telescopic rods 305 is fixedly connected to the top end of the hanger 302.

[0018] Furthermore, the moving mechanism 2 includes a pair of first guide rails 201, the top ends of which are fixedly connected to the trolley body 1. The bottom ends of the first guide rails 201 are slidably fitted with second guide rails 202. The bottom ends of the second guide rails 202 are all fixedly installed with third guide rails 211. The bottom ends of the third guide rails 211 are slidably fitted with moving frames 203. The moving frames 203 are fixedly connected to the truss 301. Through this multi-level guide rail structure, the moving mechanism 2 can achieve precise lateral movement adjustment of the guiding mechanism 3 to adapt to the operation requirements of different construction positions. The moving frames 203 serve as the carrier connecting the truss 301, ensuring that the guiding mechanism 3 can stably follow the moving mechanism 2 for lateral movement.

[0019] Furthermore, several first rollers 210 are rotatably connected to both sides of the bottom end of the first guide rail 201. The first rollers 210 are rolledly connected to the top of both sides inside the second guide rail 202. The first rollers 210 at the bottom end of the first guide rail 201 are rolledly connected to the inside of the second guide rail 202, which can convert the sliding friction between the first guide rail 201 and the second guide rail 202 into rolling friction, reducing wear. At the same time, it makes the second guide rail 202 extend and retract more smoothly along the first guide rail 201, avoiding jamming.

[0020] Furthermore, a rotating shaft is rotatably inserted at the center of the first guide rail 201, and gears 205 are fitted at both ends of the rotating shaft. Racks 204 are provided on both sides of the top of the second guide rail 202. The racks 204 and gears 205 mesh with each other. The gears 205 on the rotating shaft of the first guide rail 201 mesh with the racks 204 on the second guide rail 202, which can convert the rotational motion of the rotating shaft into the linear motion of the second guide rail 202 along the first guide rail 201, thereby realizing the stable extension and retraction of the second guide rail 202.

[0021] Furthermore, a reducer 206 is fixedly connected to one side of the first guide rail 201. The output shaft of the reducer 206 is connected to the rotating shaft. A first drive motor 207 is fixedly connected to the bottom end of the reducer 206. The output end of the first drive motor 207 is connected to the input end of the reducer 206. The first drive motor 207 provides power to the rotating shaft. The reducer 206 can reduce the output speed of the motor and increase the torque, ensuring sufficient power and smooth operation when the gear 205 and rack 204 mesh. This avoids the second guide rail 202 from losing control due to excessive speed, thus improving the operational stability of the moving mechanism 2.

[0022] Furthermore, a pair of second rollers 209 are rotatably connected to both sides of the top of the inner side of the movable frame 203. The second rollers 209 are rolledly connected to the bottom of the inner side of the third guide rail 211. The rolling connection between the second rollers 209 inside the movable frame 203 and the inner side of the third guide rail 211 reduces the frictional resistance between the movable frame 203 and the third guide rail 211, making the movable frame 203 slide more smoothly along the third guide rail 211, while reducing component wear and extending service life.

[0023] Furthermore, a second drive motor 208 is fixedly connected to both sides of the movable frame 203. The output end of the second drive motor 208 is connected to a second roller 209 at a corresponding position. The second drive motor 208 directly drives the second roller 209 to rotate, providing power for the movable frame 203 to slide along the third guide rail 211. Moreover, the sliding speed of the movable frame 203 can be precisely adjusted by controlling the motor speed, thereby improving the stability of the movement of the bottom template of the hanger 302.

[0024] Specifically, the working principle of this type of truss-type cable trough trolley is as follows: In use, firstly, the first drive motor 207 on the bottom side of the first guide rail 201 in the moving mechanism 2 is started. Its output end, after being reduced in speed and torque by the reducer 206, drives the rotating shaft to rotate. The gears 205 at both ends of the rotating shaft mesh with the rack 204 at the top of the second guide rail 202, driving the second guide rail 202 to extend and retract along the first guide rail 201. Simultaneously, the second drive motors 208 on both sides of the moving frame 203 are started, directly driving the second rollers 209 to rotate, causing the moving frame 203 to slide along the third guide rail 211. Through multi-stage adjustments, the truss 301 of the guiding mechanism 3 is moved to above the cable trough. Then, the second hydraulic telescopic rod 305 on the truss 301 is started, pushing the hanger 302 downwards, hooking the bottom hook 303 onto the template hanging ring inside the cable trough. Then, the first hydraulic telescopic rod 306 at the top of the hanger 302 is activated to push the stop block 307 against the top of the template to prevent shaking. Then, the second hydraulic telescopic rod 305 is activated in the opposite direction to lift the hanger 302. The moving mechanism 2 is adjusted by the first drive motor 207 and the second drive motor 208 to transfer the template into the trolley body 1. When the template needs to be installed, the hook 303 at the bottom of the hanger 302 is used to hang the template. The moving mechanism 2 is adjusted by the first drive motor 207 and the second drive motor 208 to move it above the cable trough. The laser positioner 304 at both ends of the hanger 302 emits a laser to calibrate the installation position. Finally, the second hydraulic telescopic rod 305 is controlled to lower the cable trough to complete the precise positioning and installation. The whole process realizes the flexible hoisting and efficient and precise construction of the cable trough.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
