DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection of the present invention is not limited to the described scope.

[0020] In order to solve the problem that traditional pipe penetration construction relies on a large amount of manpower and simple mechanical equipment, has a slow construction speed, and is easily affected by the on-site environment, and there is a risk of pipeline instability, sliding or falling during the process of pipeline penetration into the pipeline corridor, posing a threat to the safety of construction workers, the present invention proposes a pipe penetration construction auxiliary device for large-size pipelines on a pipeline corridor module.

[0021] Please refer to Figure 6 A large-size pipe threading construction auxiliary device on a pipe gallery module includes a traveling frame assembly, the traveling frame assembly includes a bearing plate 13, an auxiliary pipe threading mechanism 2 is arranged above the traveling frame assembly, the auxiliary pipe threading mechanism 2 includes an arc plate 21 with an opening upwardly fixedly installed on the top of the traveling frame assembly, the large-size pipe is placed on the opening of the arc plate 21, a mounting groove 22 penetrating the bearing plate 13 is provided at the bottom of the arc plate 21, a plurality of horizontal rotating rods 23 distributed in an array are rotatably installed between two inner walls opposite to each other in the mounting groove 22, an auxiliary wheel 24 is fixedly sleeved on the rotating rod 23, and a driving member 25 for driving the plurality of rotating rods 23 to rotate synchronously in the same direction is provided at the bottom of the arc plate 21.

[0022] Please refer to Figure 3 ,4 And 8, the driving member 25 includes a driving motor 251 installed at the bottom of the supporting plate 13, a roller gear 252 is fixedly sleeved on the output end of the driving motor 251, a roller gear 253 meshing with the roller gear 252 is fixedly sleeved on one of the rotating rods 23, a sprocket 254 is fixedly sleeved on several of the rotating rods 23, and an integrated chain 255 is sleeved on several of the sprockets 254, and a rechargeable power supply module is installed at the bottom of the supporting plate 13, and the power supply module is electrically connected to the driving motor 251.

[0023] The driving motor 1 251 drives the roller gear 1 252 to rotate, which drives the meshing roller gear 2 253 to rotate, thereby rotating the connected rotating rod 23. Under the linkage of the sprocket 254 and the chain 255, several rotating rods 23 rotate synchronously in the same direction, thereby realizing the synchronous rotation of several auxiliary wheels 24. A rechargeable and dischargeable power supply module is installed at the bottom of the supporting plate 13, and the power supply module is electrically connected to the driving motor 1 251.

[0024] The power supply module is a battery pack, which is provided with a charging manager, a DC-DC converter, a control unit, a protection circuit, a display unit and an interface circuit. The power supply module provides stable and reliable power for the drive motor and other electrical components in the pipe penetration construction auxiliary device, ensuring the efficient and safe operation of the entire system. The advantages of this component are: the meshing transmission mode of the roller gear 1 252 and the roller gear 2 253 improves the efficiency and stability of power transmission, and the chain 255 ensures that all the rotating rods 23 rotate synchronously in the same direction, providing uniform and consistent auxiliary pipe penetration power.

[0025] When the pipe-threading operation is being performed, the driving member 25 drives the plurality of rotating rods 23 to rotate synchronously, and the plurality of rotating rods 23 drive the plurality of auxiliary wheels 24 to rotate synchronously, thereby driving the pipe to move, thereby achieving the pipe-threading operation.

[0026] Both sides of the mounting groove 22 are provided with stabilizing limiting mechanisms 3 for limiting the pipe inside the opening of the arc plate 21 to prevent the pipe from shaking and falling during the pipe insertion process, causing harm to personnel, while ensuring the safety of the pipe. The two stabilizing limiting mechanisms 3 are both installed on the top of the supporting plate 13 and one end of which is movable and penetrates into the opening of the arc plate 21.

[0027] Please refer to Fig. 9 The stable limiting mechanism 3 moves through the corresponding connecting groove 211. The two connecting grooves 211 are respectively opened on the upper surface of the arc plate 21 near the two ends. The stable limiting mechanism 3 includes a connecting plate 32, a device plate 35 and a group of limiting wheels 34. The device plate 35 is located above the connecting plate 32 and is connected by a group of stabilizing rods 37. The device plate 35 is connected to a group of limiting wheels 34 that rotate uniformly along its length direction.

[0028] A connecting block 33 is symmetrically provided at the matching position of the limiting wheel 34 and the device plate 35 , and the limiting wheel 34 is connected to its corresponding connecting block 33 via a rotating shaft.

[0029] Each stabilizing rod 37 is sleeved with a spring 36, the lower end of which passes through the connecting plate 32; the combination of the spring 36 and the stabilizing rod 37 provides a flexible adjustment mechanism that can adapt to pipes of different sizes and shapes. The spring 36 can provide a buffer when the pipe contacts the limiting wheel 34, reduce impact and vibration, and protect the pipe from damage. The lower surface of the connecting plate 32 is symmetrically provided with electric push rods 31 near both ends, and the electric push rods 31 are inclined.

[0030] The electric push rod 31 is operated to be pushed out or retracted along the inclined direction, thereby pushing the connecting plate 32 to move in the connecting groove 211, and controlling the connecting plate 32 to move in the connecting groove 211 along the direction in which the pipeline is inserted to adapt to the position and angle of the pipeline. Through the movement of the connecting plate 32, the limiting wheel 34 on the connecting block 33 contacts the outer wall of the pipeline to provide stable support and guidance. When the pipeline begins to penetrate the curved plate 21, the contact between the limiting wheel 34 and the pipeline is utilized to assist the pipeline to penetrate smoothly along the curved plate 21. The stable limiting effect of the limiting wheel 34 provides stable support to prevent the pipeline from deflecting or rolling during the insertion process. The design of the electric push rod 31 enables the stable limiting mechanism 3 to adapt to pipelines of different diameters. The design of the stable limiting mechanism 3 reduces the safety risks that may occur during the pipeline penetration process, such as pipeline sliding or falling.

[0031] Please refer to Figure 1 The traveling frame assembly includes a traveling frame 1, a load-bearing plate 13 is located above the traveling frame 1, a lifting assembly 14 for adjusting the height of the load-bearing plate 13 is provided between the traveling frame 1 and the load-bearing plate 13, four traveling wheels 11 are provided at the bottom of the traveling frame 1, and a driving module 12 for driving the four traveling wheels 11 to rotate and turn is installed at the bottom of the traveling frame 1. The traveling wheels 11 are controlled by the driving module 12 so that the traveling frame 1 can be moved to the correct position of the pipe gallery module. It should be noted that the driving module 12 is a prior art and is used in current traveling vehicles such as automobiles, and will not be described in detail here.

[0032] Please refer to Fig.10The lifting assembly 14 includes two groups of symmetrically arranged scissor-type rod groups, each of which is composed of two cross-arranged support rods 141, the middle parts of the two support rods 141 are hinged, the high end of one support rod 141 is hinged to the bottom of the bearing plate 13, and the lower end thereof is rotatably mounted with a roller 142 that rolls on the top of the traveling frame 1; the lower end of the other support rod 141 is hinged to the top of the traveling frame 1, and the high end thereof is rotatably mounted with a roller 2 143 that rolls on the bottom of the bearing plate 13, and the rotating shafts of the two rollers 142 are connected with an integrated connecting rod 144.

[0033] The lifting assembly 14 also includes a plurality of oil cylinders 145 installed on the top of the traveling frame 1 and an oil supply module for supplying oil to the plurality of oil cylinders 145. The oil supply module is an important component of the hydraulic system, which is responsible for providing stable and clean hydraulic oil to the oil cylinders 145. The oil supply module is an existing structure and will not be described in detail here. The plurality of oil cylinders 145 are arranged along the traveling direction of the roller 142, and the output ends of the plurality of oil cylinders 145 are fixed with a pushing block 146 movably mounted on the connecting rod 144.

[0034] During specific operation, the lifting component 14 controls the extension and retraction of the oil cylinder 145 to push the connecting rod 144 to move. When the oil cylinder 145 extends, the push block 146 pushes the connecting rod 144, so that the two support rods 141 rotate relative to each other, the angle changes, and the load-bearing plate 13 is raised; when the oil cylinder 145 contracts, the load-bearing plate 13 is lowered to realize the lifting and lowering of the scissor-type rod group. During the lifting process, roller 1 142 and roller 2 143 ensure the smooth and coordinated movement between the walking frame 1 and the load-bearing plate 13. The design of the scissor-type rod group allows the height of the load-bearing plate 13 to be flexibly adjusted to meet the operation requirements at different heights.

[0035] In order to ensure the balance of the device and avoid the possibility of the device tipping over due to a heavy weight on one end during the pipe threading process, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 and Fig.11 A counterweight 15 is provided on the top of the traveling frame 1 to improve the stability of the device.

[0036] Specifically, a counterweight 15 is provided on the top of the traveling frame 1, and the counterweight 15 slides on the traveling frame 1. A sleeve 151 is symmetrically installed on the front and rear sides of the counterweight 15. The internal thread of the sleeve 151 is sleeved on a screw rod 152, and a driving motor 153 is installed on the end of one of the screw rods 152. A linkage wheel 154 is sleeved on the two screw rods 152, and a linkage belt 155 is sleeved between the two linkage wheels 154. Through the arrangement of the linkage wheel 154 and the linkage belt 155, the two screw rods 152 can achieve synchronous rotation, and the counterweight 15 can move more stably.

[0037] The screw rod 152 is driven to rotate by driving motor 2 153, thereby driving the counterweight 15 to move. According to the position of the pipeline during the pipe threading construction, the position of the counterweight 15 is adjusted in time to maintain the balance and stability of the device. The counterweight 15 can adjust the center of gravity of the traveling frame 1 to improve the stability of the entire device.

[0038] For further information, see Figure 8 A rubber ring 241 is fixed on the outer peripheral side of the auxiliary wheel 24. The elasticity of the rubber ring 241 helps to reduce the friction between the auxiliary wheel 24 and the pipeline, and reduces the resistance when the pipeline is passed through the pipe. The rubber ring 241 can protect the pipeline surface from wear and tear and extend the service life of the pipeline. The buffering effect provided by the rubber ring 241 helps to maintain the stability of the pipeline during the pipeline passing process.

[0039] When performing the pipe threading operation, the large-size pipe is hoisted into the opening of the arc plate 21 through the lifting equipment, the two stable limit mechanisms 3 limit the pipe, and the lifting component 14 controls the lifting of the load-bearing plate 13 until the pipe is flush with the pipe gallery module. The walking frame moves one end distance so that one end of the load-bearing plate 13 is inserted into the interior of the pipe gallery module. At this time, the driving member 25 drives several rotating rods 23 to drive the auxiliary wheels 24 to rotate. Several auxiliary wheels 24 assist the pipe to move to the interior of the pipe gallery module to complete the pipe threading construction, reducing manpower requirements and construction time, and improving the overall construction efficiency.
