Description

Technical Field

[0001] This application relates to the field of pipeline transportation, and more specifically, to an underground engineering pipe jacking transportation device. Background Technology

[0002] Pipe jacking is a trenchless pipeline laying technology used in municipal construction. Its advantages include minimal or no impact on the surrounding environment, small construction site size, low noise, and the ability to operate deep underground—advantages unmatched by open-cut pipe laying. However, pipe jacking also has disadvantages: longer construction time, higher project costs, and the use of cement pipes and steel pipes for underground projects.

[0003] While existing pipe jacking transportation systems can transport pipes of varying lengths, the weight of the pipes means that after delivery to the target location, a crane is typically needed to unload them from the transport device. This process is cumbersome, time-consuming, labor-intensive, and inefficient. Furthermore, the complex terrain and limited space in some areas make it difficult to use both the transport device and the crane simultaneously, further complicating the loading and unloading of the pipes and reducing overall transport and handling efficiency.

[0027] The features and performance of the underground engineering pipe jacking transportation device of this application will be further described in detail below with reference to the embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application embodiment provides an underground engineering pipe jacking transportation device, which includes two parallel and oppositely arranged base plates 100, two gantry frames 110, two connecting plates 120 corresponding to the base plates 100, two lifting plates 130, two side fixing components 200 corresponding to the connecting plates 120, and two end fixing components 300 corresponding to the lifting plates 130. Each base plate 100 has a rotatable moving wheel 140 connected to both ends. The bottom ends of each gantry frame 110 are connected to one end of the two base plates 100. The connecting plates 120 are located above the corresponding base plates 100 and are connected to one end of the two gantry frames 110. The two ends of each lifting plate 130 are movably connected to the two ends of the gantry frame 110. The gantry frame 110 is also connected to a lifting component 400 for driving the corresponding lifting plate 130 to rise and fall.

[0029] Each side fixing component 200 includes two first hydraulic telescopic rods 220 and an arc-shaped clamping plate 210. The two ends of the first hydraulic telescopic rods 220 are respectively connected to the protruding side of the corresponding connecting plate 120 and the arc-shaped clamping plate 210. The two arc-shaped clamping plates 210 are respectively located on the adjacent side of the connecting plate 120 of the two side fixing components 200. A rubber pad 230 is provided on the side of the arc-shaped clamping plate 210 away from the connecting plate 120. When the first hydraulic telescopic rods 220 of the two side fixing components 200 extend and retract, they push the two arc-shaped clamping plates 210 to move towards each other or away from each other to press against or loosen the two side walls of the jacking pipe.

[0030] Each end fixing component 300 includes a positioning plate 310 and a second hydraulic telescopic rod 330 connected to the lifting plate 130 and the positioning plate 310 at both ends respectively. The positioning plate 310 has six extrusion blocks 320 arranged circumferentially on its outer side and six third hydraulic telescopic rods 340 corresponding to the extrusion blocks 320. A fixing ring 350 is sleeved on the outer side of the positioning plate 310. Each third hydraulic telescopic rod 340 passes through the fixing ring 350 and its two ends are connected to the positioning plate 310 and the corresponding extrusion block 320 respectively. When the third hydraulic telescopic rod 340 extends or retracts, it pushes the corresponding extrusion block 320 to move radially along the positioning plate 310. When the two second hydraulic telescopic rods 330 extend or retract, they push the two positioning plates 310 to insert into or remove from both ends of the jacking pipe. When the positioning plate 310 is inserted into the end of the jacking pipe, it causes the corresponding extrusion block 320 to move radially and press against or loosen the inner wall of both ends of the jacking pipe.

[0031] The lifting assembly 400 includes two lead screws 410 that are threaded through both ends of the lifting plate 130, a first transmission gear 420 connected to the two lead screws 410, a gear chain 430 with both ends sleeved on the two first transmission gears 420, a second transmission gear 440 meshing with the gear chain 430, and a transmission motor 450 fixed to the top of the gantry frame 110. The second transmission gear 440 is connected to the output shaft of the transmission motor 450. The top of the gantry frame 110 is provided with a mounting groove 160. The first transmission gear 420, the second transmission gear 440, and the gear chain 430 are rotatably arranged in the mounting groove 160. The two adjacent sides of the two ends of the gantry frame 110 are recessed to form lifting slide grooves 150. The two ends of the lifting plate 130 are slidably inserted into the two lifting slide grooves 150.

[0032] The working principle of the underground engineering pipe jacking and transportation device provided in this application embodiment is as follows:

[0033] When transporting the jacking pipe, the two base plates 100 are connected to two movable wheels 140 to move the underground engineering jacking pipe transport device. This moves the two base plates 100 to both sides of the outer wall of the hoisted jacking pipe, and positions the two gantry frames 110 above the outer sides of the jacking pipe. At this time, the drive motors 450 controlling the lifting components 400 at the top of the two gantry frames 110 operate simultaneously. The output shaft of the drive motor 450 drives the second drive gear 440 to rotate. Since the second drive gear 440 is connected to the gear chain 430... The second transmission gear 440 meshes with two first transmission gears 420, so when the second transmission gear 440 rotates, it drives the first transmission gear 420 to rotate simultaneously, thereby driving the two lead screws 410 to rotate simultaneously in the same direction. The two rotating lead screws 410 drive the lifting plate 130 to rise and fall until the lifting plate 130 is aligned with the end opening of the jacking pipe by the positioning plate 310 connected by the second hydraulic telescopic rod 330, so that the positioning plates 310 of the two end fixing components 300 are respectively on the same horizontal line with the center of the jacking pipe. Then, the two second hydraulic telescopic rods 330 are controlled to extend and push the two The positioning plate 310 moves closer to the jacking pipe and inserts into both ends of the jacking pipe. Then, the six third hydraulic telescopic rods 340 of the two end fixing components 300 extend and push the corresponding extrusion blocks 320 to move radially along the positioning plate 310, pressing against the inner wall of the jacking pipe. Thus, the two ends of the jacking pipe are fixed by the two end fixing components 300. At this time, the drive motors 450 on the two gantry frames 110 rotate in opposite directions simultaneously, thereby driving the lifting plate 130 to move upward. The lifting plate 130 drives the second hydraulic telescopic rod 330 and the two end fixing components 300 to move upward. The device moves, causing both ends of the jacking pipe to rise away from the ground. When the jacking pipe is transported between the two connecting plates 120, the first hydraulic telescopic rods 220 of the two side fixing components 200 are extended, thereby causing the two oppositely arranged arc-shaped clamping plates 210 to move towards each other. The rubber pads 230 set on the adjacent side of the two arc-shaped clamping plates 210 press against the two side walls of the jacking pipe to clamp the jacking pipe, preventing the jacking pipe from shaking during transportation and improving the stability of the jacking pipe. Finally, the underground engineering jacking pipe transportation device is moved to the designated position by a tractor vehicle.

[0034] When the jacking pipe needs to be unloaded, the two first hydraulic telescopic rods 220 are controlled to retract, causing the two arc-shaped clamps 210 to move away from each other and loosen the jacking pipe. Then, the lifting assembly 400 drives the two end fixing assemblies 300 to move downwards and place the jacking pipe on the ground. Finally, the six third hydraulic telescopic rods 340 of the end fixing assemblies 300 are controlled to retract, causing the corresponding pressing blocks 320 to move in the opposite direction along the positioning plate 310 to loosen the inner wall of the jacking pipe. The second hydraulic telescopic rod 330 is controlled to retract, causing the positioning plate 310 and the pressing blocks 320 to detach from the end of the jacking pipe. Thus, the two end fixing assemblies 300 are detached from the jacking pipe, thereby unloading the jacking pipe. Then, the lifting assembly 400 can be controlled to raise the end fixing assemblies 300 and move the underground engineering jacking pipe transportation device away from the top of the jacking pipe to complete the movement and loading / unloading operation of the jacking pipe.

[0035] The underground pipe jacking transportation device provided in this application embodiment, by cooperating with two end fixing components 300 and a lifting component 400, can fix both ends of the pipe in a confined space and raise or lower the pipe. In cooperation with two side fixing components 200 for clamping or loosening the sides of the pipe, it can stably raise, lower and fix the pipe for loading, unloading and transportation. After transporting the pipe to the designated location, the fixing of both sides of the pipe is loosened and the lifting component 400 is used to place the pipe on the ground and finally loosen both ends of the pipe. This realizes the rapid loading, unloading and transportation of the pipe in a confined space, effectively improving the transportation efficiency of the pipe in a confined space.

The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
