Description

Technical Field

[0001] This application belongs to the field of water conservancy engineering equipment technology, and in particular relates to a water conservancy engineering pipe jacking equipment. Background Technology

[0002] Pipe jacking is a pipeline laying technology that requires little or no excavation. Pipe jacking construction involves using the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, pushing the pipeline into the soil at the designed slope, and then removing the excavated soil. After one section of the pipe is pushed into the soil, the second section of the pipe is pushed in to continue the jacking process.

[0003] Patent CN111764922B discloses a pipe jacking machine for water conservancy projects, including a base and a pipe jacking machine body installed on the base. The base is connected to an adjustable seat that can be raised and lowered. The pipe jacking machine body is installed on the adjustable seat. The base is provided with a support device for supporting the adjustable seat. The support device includes an abutment plate and a stacking plate. The side wall of the base is provided with a movable groove for accommodating the abutment plate. Several stacking plates are connected to the abutment plate, and the abutment plate rotates to abut against the upper part of the base and support the bottom of the adjustable seat.

[0004] The aforementioned patent allows for adjustment of the lifting and lowering of the pipe jacking machine by setting an adjustment seat to adapt to changes in the pipe installation height. However, in actual use, the lack of a corresponding guiding structure can easily lead to deviation when pushing the pipe, requiring improvement. Summary of the Invention

[0005] The purpose of this application is to provide a pipe jacking device for water conservancy projects that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a pipe jacking device for water conservancy projects, comprising:

[0007] Base;

[0008] The pipe jacking mechanism, mounted on the base, pushes the pipe and overcomes the friction between the pipe and the surrounding soil;

[0009] A guiding mechanism, mounted on the base, is used to support and guide the pipe being pushed;

[0010] The base includes a bottom plate and a back plate. The back plate is vertically mounted on the bottom plate, and the jacking mechanism is connected to the back plate.

[0011] The aforementioned pipe jacking equipment for hydraulic engineering utilizes a base, which serves as the supporting structure for the entire device. The base consists of a bottom plate and a back plate. The bottom plate is used to stably place the pipe on the ground, while the back plate is vertically mounted on the bottom plate, providing support and connection points for the pipe jacking mechanism. The pipe jacking mechanism is mounted on the back plate of the base, and its main function is to push the pipe and overcome the friction between the pipe and the surrounding soil, ensuring that the pipe can smoothly enter the predetermined position. A guiding mechanism is mounted on the base to support and guide the jacked pipe, ensuring that the pipe does not deviate from the predetermined trajectory during the pushing process. The guiding mechanism effectively solves the problem of pipe deviation during pushing, improving construction accuracy and efficiency.

[0012] Furthermore, the pipe jacking mechanism includes:

[0013] Mounting bracket, set on the base plate and connected to the back plate;

[0014] Hydraulic cylinders are mounted on a mounting bracket, and multiple cylinders are provided. A pressure equalizing ring is provided on the output end of the hydraulic cylinder.

[0015] The guide rail is mounted on the base plate;

[0016] The head is slidably fitted with the guide rail, and the end of it away from the equalizing ring is equipped with a cutter head for breaking the soil;

[0017] The cylinder's output end extends, causing the equalizing ring to extend forward, pushing the machine head towards the soil. At the same time, the cutter head rotates to break up the soil, and then the pipe to be pushed is gradually placed on the guide rail and poured into the side of the equalizing ring.

[0018] The mounting bracket, set on the base plate, supports the hydraulic cylinders and ensures the stability of the pipe jacking mechanism during operation. The number of hydraulic cylinders mounted on the bracket can be configured according to actual needs, typically multiple cylinders, to provide sufficient thrust to push the pipe. An equalizing ring is installed at the output end of each cylinder; its function is to evenly distribute the thrust generated by the cylinder, preventing excessive concentrated force on the pipe during pushing and causing damage. When the cylinder operates, its output end extends, causing the equalizing ring to extend forward, thereby pushing the jacking head towards the soil. A guide rail, set on the base plate, slides with the jacking head, providing a stable track for its movement. The jacking head, sliding with the guide rail, has a cutterhead at its end away from the equalizing ring for breaking up the soil. The cutterhead breaks up the soil, providing a channel for pushing the pipe.

[0019] As the hydraulic cylinder pushes the cutter head towards the soil, the cutter head begins to rotate, breaking up the soil. As the cutter head advances, the soil is gradually broken up, creating a channel to place the pipe to be pushed onto the guide rail and into one side of the equalizing ring. The hydraulic cylinder operates, extending its output end and causing the equalizing ring to extend forward. The equalizing ring pushes the cutter head along the guide rail towards the soil, and the cutter head on the cutter head begins to rotate, breaking up the soil. The soil is gradually broken up, creating a channel to place the pipe to be pushed onto the guide rail and into one side of the equalizing ring. The hydraulic cylinder continues to operate, pushing the pipe forward along the channel until it reaches the predetermined position.

[0020] Furthermore: the guiding mechanism includes:

[0021] A first support rod is mounted on the base plate, and a first telescopic component is installed inside it. A first roller is installed at the end of the first telescopic component.

[0022] The second support rod is installed on the base plate, and a second telescopic component is installed inside it. A second roller is installed at the end of the second telescopic component.

[0023] The system includes multiple first and second support rods. The first support rods are inclined and symmetrically arranged on both sides of the base plate, and the second support rods are located between the first support rods.

[0024] The first support rod is mounted on the base plate and symmetrically positioned at an angle on both sides of the base plate. This angled arrangement provides better support and helps guide the pipe forward in a predetermined direction. The first support rod contains a first telescopic component, which can extend and retract to adjust its length to accommodate pipes of different diameters. A first roller is located at the end of the first telescopic component, reducing friction between the pipe and the support rod, allowing for smoother pipe movement. The second support rod is also mounted on the base plate, positioned between the first support rods. The second support rod further enhances the support and guidance effect on the pipe. Similar to the first support rod, the second support rod also contains a second telescopic component to adjust its length to accommodate pipes of different diameters. A second roller is located at the end of the second telescopic component, also reducing friction between the pipe and the support rod, allowing for smoother pipe movement.

[0025] When the pipe is pushed by the pipe jacking mechanism, the first and second rollers support and guide the pipe. Because the first support rods are symmetrically positioned on both sides of the base plate, while the second support rod is located between the first support rods, this arrangement ensures that the pipe does not deviate from its predetermined trajectory during the pushing process. Simultaneously, the adjustable functions of the first and second telescopic components can accommodate pipes of different diameters, giving the guiding mechanism better versatility and adaptability.

[0026] Furthermore, both the first and second telescopic members are connected to an adjustment structure, which includes:

[0027] The first screw is mounted on the second support rod and the first support rod;

[0028] The second screw is disposed inside the second support rod and the first support rod and is threadedly connected to the first telescopic member and the second telescopic member;

[0029] The mating parts include a first bevel gear connected to the first screw and a second bevel gear connected to the second screw;

[0030] The driver is connected to the first screw and is provided on both the second support rod and the first support rod.

[0031] In this configuration, the first bevel gear meshes with the second bevel gear, and the driver drives the first telescopic component and the second telescopic component to extend and retract by rotating the first screw.

[0032] A first screw is mounted on the second and first support rods and connects to the driver. A second screw is located inside the second and first support rods and is threadedly connected to the first and second telescopic components. Rotating the second screw allows for the extension and retraction adjustment of the first and second telescopic components. The mating components include a first bevel gear connected to the first screw and a second bevel gear connected to the second screw. The first and second bevel gears mesh with each other to form a gear transmission mechanism. When the driver drives the first screw to rotate, the first bevel gear rotates accordingly and, through meshing, drives the second bevel gear to rotate. Since the second bevel gear is connected to the second screw, the second screw also rotates, thus achieving the extension and retraction adjustment of the first and second telescopic components. The driver is located outside the second and first support rods and connects to the first screw. By driving the first screw to rotate, and through the mating components, driving the second screw to rotate, the extension and retraction adjustment of the first and second telescopic components is achieved.

[0033] When it is necessary to adjust the lengths of the first and second telescopic components to accommodate pipes of different diameters, the actuator is first activated. The actuator drives the first screw to rotate, which in turn rotates the first bevel gear, driving the second bevel gear to rotate through meshing. Since the second bevel gear is connected to the second screw, the second screw also rotates. As the second screw rotates, the first and second telescopic components extend and retract along the thread direction of the screw, thereby adapting to the pipe diameter. By driving the screw to rotate, precise adjustment of the first and second telescopic components can be achieved, ensuring that the guiding mechanism can adapt to pipes of different diameters. Simultaneously, the design of the adjustment structure makes the entire guiding mechanism compact, space-saving, and easy to arrange and install on the construction site.

[0034] Furthermore, the height of the second support rod is lower than the height of the first support rod, and the first screw passes through multiple second support rods and the first support rod in sequence.

[0035] The first and second support rods have a certain height difference in the vertical direction. This arrangement provides better support and guidance for the pipeline, offering more stable support. The first screw is designed to pass sequentially through multiple second support rods and the first support rod. This through-type design allows a single actuator to simultaneously drive the first and second telescopic components on multiple second support rods and the first support rod for telescopic adjustment.

[0036] When the driver starts, it drives the first screw to rotate. Since the first screw passes sequentially through multiple second support rods and the first support rod, it simultaneously drives the first and second bevel gears on these support rods to rotate. These bevel gears then drive their respective connected second screws to rotate, achieving synchronous extension and retraction adjustment of multiple first and second telescopic components, thus improving construction efficiency.

[0037] Furthermore, the tangent points of the first roller, the second roller, and the pipe form an external tangent circle, and the external tangent circle and the equalizing ring are located on the same axis.

[0038] By aligning the circumscribed circle formed by the roller contact point with the equalizing ring on the same axis, the offset and swaying of the pipeline during the pushing process can be minimized, thereby improving the accuracy and stability of the construction.

[0039] The beneficial effects of this application are:

[0040] 1. By setting up a guiding mechanism, the problem of pipe offset during pipeline pushing can be effectively solved, improving the accuracy and efficiency of construction;

[0041] 2. By driving the screw to rotate through the driver, the first and second telescopic components can be precisely adjusted, ensuring that the guiding mechanism can adapt to pipes of different diameters. At the same time, the design of the adjustment structure makes the entire guiding mechanism compact and space-saving, making it easy to arrange and install on the construction site.

[0042] 3. By placing the circumscribed circle formed by the roller contact point on the same axis as the equalizing ring, the offset and swaying of the pipeline during the pushing process can be minimized, thereby improving the accuracy and stability of the construction.

[0051] The following description, in conjunction with the accompanying drawings, details the water conservancy engineering pipe jacking equipment provided in this application through specific embodiments and application scenarios.

[0052] Example 1:

[0053] like Figure 1 and Figure 2 As shown in the figure, this application provides a pipe jacking device for water conservancy projects, including:

[0054] Base 100;

[0055] The pipe jacking mechanism 200 is mounted on the base 100 to push the pipe and overcome the friction between the pipe and the surrounding soil.

[0056] The guide mechanism 300 is mounted on the base 100 and is used to support and guide the pipe being pushed.

[0057] The base 100 includes a base plate 110 and a back plate 120. The back plate 120 is vertically mounted on the base plate 110, and the jacking mechanism 200 is connected to the back plate 120.

[0058] In some embodiments of this application, such as Figure 1 As shown, the aforementioned pipe jacking equipment for water conservancy projects utilizes a base 100, which serves as the supporting structure for the entire equipment. The base 100 consists of a base plate 110 and a back plate 120. The base plate 110 is used to stably place the pipe on the ground, while the back plate 120 is vertically mounted on the base plate 110, providing support and connection points for the pipe jacking mechanism 200. The pipe jacking mechanism 200 is mounted on the back plate 120 of the base 100, and its main function is to push the pipe and overcome the friction between the pipe and the surrounding soil, ensuring that the pipe can smoothly enter the predetermined position. A guiding mechanism 300 is mounted on the base 100 and is used to support and guide the jacked pipe, ensuring that the pipe does not deviate from the predetermined trajectory during the pushing process. The guiding mechanism 300 effectively solves the problem of pipe deviation during pushing, improving the accuracy and efficiency of construction.

[0059] Example 2:

[0060] This application provides a pipe jacking device for water conservancy projects. In addition to the above-mentioned technical features, the pipe jacking device for water conservancy projects in this application also includes the following technical features.

[0061] like Figure 1 and Figure 2 As shown, the pipe jacking mechanism 200 includes:

[0062] Mounting bracket 210 is mounted on base plate 110 and connected to back plate 120;

[0063] Hydraulic cylinder 220 is mounted on mounting bracket 210 and multiple cylinders are provided. A pressure equalizing ring 230 is provided on the output end of hydraulic cylinder 220.

[0064] Guide rail 240 is mounted on base plate 110;

[0065] The head 250 slides with the guide rail 240, and a cutter head 260 for breaking soil is provided at the end away from the equalizing ring 230.

[0066] In this process, the extension of the output end of the hydraulic cylinder 220 causes the equalizing ring 230 to extend forward, pushing the machine head 250 towards the soil. At the same time, the cutter head 260 is turned on to rotate and crush the soil. Then, the pipe to be pushed is gradually placed on the guide rail 240 and poured into one side of the equalizing ring 230.

[0067] In this embodiment, the mounting bracket 210 is mounted on the base plate 110 to support the hydraulic cylinder 220 and ensure the stability of the pipe jacking mechanism 200 during operation. The hydraulic cylinders 220 are mounted on the mounting bracket 210, and their number can be configured according to actual needs, typically multiple, to provide sufficient thrust to push the pipe. A pressure equalizing ring 230 is provided on the output end of the hydraulic cylinder 220. The function of the pressure equalizing ring 230 is to evenly distribute the thrust generated by the hydraulic cylinder 220, preventing the pipe from being damaged by excessive concentrated force during the pushing process. When the hydraulic cylinder 220 operates, its output end extends, causing the pressure equalizing ring 230 to extend forward, thereby pushing the head 250 towards the soil. The guide rail 240 is mounted on the base plate 110 and slides in cooperation with the head 250, providing a stable track for the head 250. The head 250 slides in cooperation with the guide rail 240, and a cutterhead 260 for breaking the soil is provided at the end away from the pressure equalizing ring 230. The cutterhead 260 is used to break up the soil and provide a channel for pushing the pipeline.

[0068] As the hydraulic cylinder 220 pushes the cutting head 250 towards the soil, the cutter head 260 begins to rotate, breaking up the soil. As the cutting head 250 advances, the soil is gradually broken up, forming a channel to place the pipe to be pushed onto the guide rail 240 and into one side of the equalizing ring 230. The hydraulic cylinder 220 operates, its output end extending and causing the equalizing ring 230 to extend forward. The equalizing ring 230 pushes the cutting head 250 along the guide rail 240 towards the soil. The cutter head 260 on the cutting head 250 begins to rotate, breaking up the soil. The soil is gradually broken up, forming a channel to place the pipe to be pushed onto the guide rail 240 and into one side of the equalizing ring 230. The hydraulic cylinder 220 continues to operate, pushing the pipe forward along the channel until it reaches the predetermined position.

[0069] Example 3:

[0070] This application provides a pipe jacking device for water conservancy projects. In addition to the above-mentioned technical features, the pipe jacking device for water conservancy projects in this application also includes the following technical features.

[0071] like Figures 3 to 5 As shown, the guiding mechanism 300 includes:

[0072] The first support rod 310 is mounted on the base plate 110, and a first telescopic member 320 is provided inside it. The end of the first telescopic member 320 is provided with a first roller 330.

[0073] The second support rod 340 is mounted on the base plate 110, and a second telescopic member 350 is provided inside it. A second roller 360 is provided at the end of the second telescopic member 350.

[0074] The first support rod 310 and the second support rod 340 are provided in multiples. The first support rod 310 is inclined and symmetrically arranged on both sides of the base plate 110, and the second support rod 340 is located between the first support rods 310.

[0075] In this embodiment, the first support rod 310 is disposed on the base plate 110 and is symmetrically and obliquely disposed on both sides of the base plate 110. The oblique arrangement provides better support and helps guide the pipeline to move in a predetermined direction. The first support rod 310 has a first telescopic member 320 inside, which can extend and retract to adjust its length to accommodate pipelines of different diameters. The end of the first telescopic member 320 is provided with a first roller 330, which reduces friction between the pipeline and the support rod, allowing the pipeline to move more smoothly. The second support rod 340 is also disposed on the base plate 110, located between the first support rods 310. The second support rod 340 further enhances the support and guidance effect on the pipeline. Similar to the first support rod 310, the second support rod 340 also has a second telescopic member 350 inside, used to adjust the length of the support rod to accommodate pipelines of different diameters. The end of the second telescopic member 350 is provided with a second roller 360. The roller is also used to reduce the friction between the pipe and the support rod, so that the pipe can move more smoothly.

[0076] When the pipe is pushed by the pipe jacking mechanism 200, the first roller 330 and the second roller 360 support and guide the pipe. Since the first support rod 310 is symmetrically arranged on both sides of the base plate 110, and the second support rod 340 is located between the first support rods 310, this arrangement ensures that the pipe does not deviate from the predetermined trajectory during the pushing process. Simultaneously, the adjustable functions of the first telescopic member 320 and the second telescopic member 350 can accommodate pipes of different diameters, giving the guiding mechanism 300 better versatility and adaptability.

[0077] Example 4:

[0078] This application provides a pipe jacking device for water conservancy projects. In addition to the above-mentioned technical features, the pipe jacking device for water conservancy projects in this application also includes the following technical features.

[0079] like Figures 3 to 5 As shown, both the first telescopic member 320 and the second telescopic member 350 are connected to an adjustment structure 400, which includes:

[0080] The first screw 410 is mounted on the second support rod 340 and the first support rod 310;

[0081] The second screw 420 is disposed in the second support rod 340 and the first support rod 310 and is threadedly connected to the first telescopic member 320 and the second telescopic member 350.

[0082] The mating parts include a first bevel gear 430 connected to the first screw 410 and a second bevel gear 440 connected to the second screw 420;

[0083] The driver 450 is connected to the first screw 410 and is provided on both the second support rod 340 and the first support rod 310.

[0084] In this configuration, the first bevel gear 430 meshes with the second bevel gear 440, and the driver 450 drives the first telescopic member 320 and the second telescopic member 350 to extend and retract by rotating the first screw 410.

[0085] In this embodiment, a screw 410 is disposed on the second support rod 340 and the first support rod 310, for connecting the driver 450. A second screw 420 is disposed inside the second support rod 340 and the first support rod 310, and is threadedly connected to the first telescopic member 320 and the second telescopic member 350. By rotating the second screw 420, the telescopic adjustment of the first telescopic member 320 and the second telescopic member 350 can be achieved. The mating components include a first bevel gear 430 connected to the first screw 410 and a second bevel gear 440 connected to the second screw 420. The first bevel gear 430 and the second bevel gear 440 mesh with each other to form a gear transmission mechanism. When the driver 450 drives the first screw 410 to rotate, the first bevel gear 430 rotates accordingly, and drives the second bevel gear 440 to rotate through the meshing relationship. Since the second bevel gear 440 is connected to the second screw 420, the second screw 420 also rotates, thereby achieving the telescopic adjustment of the first telescopic member 320 and the second telescopic member 350. The driver 450 is disposed outside the second support rod 340 and the first support rod 310 and is connected to the first screw 410. By driving the first screw 410 to rotate, and driving the second screw 420 to rotate through the mating parts, the extension and retraction adjustment of the first telescopic member 320 and the second telescopic member 350 can be realized.

[0086] When the lengths of the first telescopic component 320 and the second telescopic component 350 need to be adjusted to accommodate pipes of different diameters, the actuator 450 is first activated. The actuator 450 drives the first screw 410 to rotate, which in turn rotates the first bevel gear 430, driving the second bevel gear 440 to rotate through meshing. Since the second bevel gear 440 is connected to the second screw 420, the second screw 420 also rotates. As the second screw 420 rotates, the first telescopic component 320 and the second telescopic component 350 extend and retract along the thread direction of the screw, thereby adapting to the pipe diameter. By driving the screw to rotate through the actuator 450, precise adjustment of the first telescopic component 320 and the second telescopic component 350 can be achieved, ensuring that the guide mechanism 300 can adapt to pipes of different diameters. Simultaneously, the design of the adjustment structure 400 makes the entire guide mechanism 300 compact, space-saving, and easy to arrange and install on the construction site.

[0087] Furthermore, the height of the second support rod 340 is lower than the height of the first support rod 310, and the first screw 410 passes through multiple second support rods 340 and first support rods 310 in sequence.

[0088] In some embodiments of this application, the first support rod 310 and the second support rod 340 have a certain height difference in the vertical direction. This arrangement can better support and guide the pipe, providing more stable support. The first screw 410 is designed to pass through multiple second support rods 340 and the first support rod 310 in sequence. This through-through design allows one actuator 450 to simultaneously drive the first telescopic member 320 and the second telescopic member 350 on multiple second support rods 340 and the first support rod 310 for telescopic adjustment.

[0089] When the driver 450 is activated, it drives the first screw 410 to rotate. Since the first screw 410 passes sequentially through multiple second support rods 340 and the first support rod 310, it simultaneously drives the first bevel gears 430 and second bevel gears 440 on these support rods to rotate. These bevel gears then drive their respective connected second screws 420 to rotate, achieving synchronous extension and retraction adjustment of multiple first telescopic components 320 and second telescopic components 350, thus improving construction efficiency.

[0090] Example 5:

[0091] This application provides a pipe jacking device for water conservancy projects. In addition to the above-mentioned technical features, the pipe jacking device for water conservancy projects in this application also includes the following technical features.

[0092] like Figures 3 to 5 As shown, the first roller 330, the second roller 360 and the tangent point of the pipe form an outer tangent circle, and the outer tangent circle and the equalizing ring 230 are located on the same axis.

[0093] In this embodiment, by placing the circumscribed circle formed by the roller contact point on the same axis as the equalizing ring 230, the offset and swaying of the pipeline during the pushing process can be minimized, thereby improving the accuracy and stability of the construction.
