The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figures 1 to 4 As shown, the present invention provides a pipe jacking angle adjustment device for pipe jacking construction, comprising: a base 1, a drive motor 2, a turntable 3, a base plate 4, and a clamping plate 5.

[0022] In this embodiment, the base 1 includes an upper ring plate 11 , a lower ring plate 12 , and support columns 13 .

[0023] The upper ring plate 11 and the lower ring plate 12 are coaxially arranged. The upper ring plate 11 is arranged directly above the lower ring plate 12. A support column 13 is connected between the upper ring plate 11 and the lower ring plate 12.

[0024] Preferably, support columns are connected to opposite sides of the upper ring plate and opposite sides of the lower ring plate. The support columns are arranged along the axial direction of the upper ring plate. Ear plates are formed at both ends of the support columns. The upper ear plate of the support plate is bolted to the upper ring plate, while the lower ear plate of the support plate is bolted to the lower ring plate.

[0025] A chassis 21 is movably provided in the inner ring hole of the lower ring plate 12. A gap 20 is formed between the chassis 21 and the hole wall of the inner ring hole of the lower ring plate 12. The gap 20 is annular. The drive motor 2 is vertically arranged on the chassis 21.

[0026] The turntable 3 is rotatably disposed in the inner ring hole of the upper ring plate 11. As a preferred embodiment, the inner diameter of the inner ring hole of the upper ring plate 11 is adapted to the outer diameter of the turntable 3.

[0027] The output end of the driving motor is coaxially connected to the turntable 3. Suspension rods 31 are connected to opposite sides of the turntable 3. The lower ends of the suspension rods 31 movably pass through the gap 20 and extend below the lower ring plate 12.

[0028] As a preferred embodiment, the outer diameter of the suspension rod 31 is adapted to the width of the gap 20.

[0029] Combined with Figure 1 and Figure 4 As shown, the substrate 4 is attached to the bottom of the lower ring plate 12. The substrate 4 is connected to the lower end of the suspension rod 31. A chute 40 is provided at the bottom of the substrate 4 and is arranged in the radial direction of the lower ring plate 12. A lower probe rod 41 is slidably arranged in the chute 40.

[0030] The number of clamping plates 5 is two. The two clamping plates 5 are attached to each other. Accommodating through grooves are formed on the opposite sides of the two clamping plates 5. The two accommodating through grooves enclose a passage for clamping the jacking pipe.

[0031] In this embodiment, the inner wall of the accommodating through groove is arc-shaped.

[0032] The lower end of the lower probe rod 41 extends below the chute 40, and the lower end of the lower probe rod 41 is connected to the clamping plate 5.

[0033] As a preferred embodiment, the lower end of the lower probe rod 41 is connected to the outer arc surface of the clamping plate 5.

[0034] An elastic member 42 is installed in the chute 40. The elastic member 42 is used to push the lower probe rod 41 so that the lower probe rod 41 faces the end of the chute 40 close to the center of the lower ring plate 12, thereby causing the two clamping plates to approach each other and press against each other.

[0035] As a preferred embodiment, the elastic member 42 is a spring.

[0036] In this embodiment, continuing to combine Figure 4 As shown, the spring is connected to the lower probe rod 41 and the other end of the chute 40 away from the center of the circle.

[0037] As a preferred embodiment, the clamping plate 5 is arc-shaped. Arc-shaped plates 51 are elastically connected to opposite sides in the width direction of the inner arc surface of the clamping plate 5. The arc-shaped plates 51 are coaxially arranged with the clamping plate 5.

[0038] The arc-shaped plates are elastically installed on the inner arc surface of the clamping plate through a plurality of springs. The plurality of springs are arranged in a matrix.

[0039] The present invention provides a construction method for a jacking pipe angle adjustment device for jacking pipe construction, including the following steps: S1. Open the two clamping plates 5 and place the jacking pipe between the two clamping plates 5.

[0040] In this embodiment, the jacking pipe is disposed between the arc-shaped plates on the inner arc surfaces of the two clamping plates after the two clamping plates are stretched apart.

[0041] S2. Release the two clamping plates 5. The two clamping plates 5 are pushed closer to each other by the elastic member 42, so that the accommodating grooves of the two clamping plates 5 are enclosed to form a channel for clamping the jacking pipe.

[0042] After the pulling force for spreading the two clamping plates is eliminated, the arc-shaped plates of the two clamping plates are pressed against the opposite sides of the jacking pipe, so that the jacking pipe is firmly arranged between the two clamping plates.

[0043] S3, the driving motor 2 is started to drive the turntable 3 to rotate, and the turntable 3 drives the suspension rod 31 to rotate along the circumferential direction of the base 1, so that the jacking pipe clamped by the two clamping plates 5 produces an angular deflection.

[0044] In this embodiment, the drive motor is a forward and reverse motor. When the drive motor rotates forward, the jacking pipe is angularly deflected toward the left side in the jacking pipe excavation direction; when the drive motor rotates reversely, the jacking pipe is angularly deflected toward the right side in the jacking pipe excavation direction.

[0045] The jacking pipe angle adjustment device for jacking pipe construction of the present invention occupies a construction site efficiently, simplifies the fixation of the jacking pipe, can accurately adjust the jacking pipe angle, and is suitable for jacking pipes of different sizes.

[0046] The jacking pipe angle adjustment device for jacking pipe construction of the present invention uses a driving motor as the core power source, and transmits power to various components through a transmission shaft to ensure the precise adjustment of the jacking pipe angle. The cooperation between the slide groove of the base plate and the lower probe rod enables the clamping plate to move flexibly to meet the adjustment requirements of different angles. The arc plate elastically mounted on the inner arc surface of the clamping plate further enhances the stability of the clamping plate, ensuring that the jacking pipe can be firmly clamped during the adjustment process, always maintaining stability, and preventing displacement during construction. The arc plate is elastically mounted on the clamping plate by a spring to enhance the stability of the device, provide necessary buffering when adjusting the angle, and protect the jacking pipe from impact.

[0047] The spring's pushing force is used in the slide groove of the base plate to provide stable support and pushing force for the lower probe rod, ensuring the accuracy and stability of the top pipe angle adjustment.

[0048] The pipe jacking angle adjustment device for pipe jacking construction of the present invention has a compact structure, is easy to operate, and can be adjusted accurately and stably. Its application can greatly improve the efficiency and quality of pipe jacking construction and reduce construction costs.

[0049] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
