[0024] See also Figure 1-Figure 5 A power device for pipe jacking includes a support mechanism 100 and a clamping mechanism 200 rotatably arranged on the top thereof. The support mechanism 100 includes a support plate 101:

[0025] The support plate 101 serves as the basis of the support mechanism 100 and provides a stable support platform to ensure the stability of the device during construction.

[0026] Furthermore, the clamping mechanism 200 includes a mounting plate 201 rotatably set on the top of the support plate 101, and the front and rear positions on the left and right sides of the top of the mounting plate 201 are correspondingly rotatably connected with the No. 2 electric push rods 203. There are four No. 2 electric push rods 203 in total, and the four No. 2 electric push rods 203 are arranged in groups of two on the left and right sides of the top of the mounting plate 201 front and back. The front and rear telescopic ends of the No. 2 electric push rods 203 are rotatably connected with the clamping parts 204, and the clamping parts 204 are correspondingly arranged on the left and right sides of the top of the mounting plate 201.

[0027] The mounting plate 201 is rotatably mounted on the top of the support plate 101, allowing the angle of the jacking pipe to be adjusted. Four No. 2 electric push rods 203 are provided, located at the front and rear positions on the left and right sides of the top of the mounting plate 201. The No. 2 electric push rod 203 drives the clamping piece 204 to adjust the height of the jacking pipe through telescopic action. The clamping piece 204 is rotatably connected to the telescopic end of the No. 2 electric push rod 203, and can flexibly adjust its position to ensure that the jacking pipe is stably fixed at different angles.

[0028] Furthermore, multiple No. 1 electric push rods 102 are rotatably connected to the right side of the top of the support plate 101. Multiple No. 1 electric push rods 102 are tiltedly set on the top of the support plate 101, and the top telescopic ends of multiple No. 1 electric push rods 102 are rotatably connected to the bottom center of the mounting plate 201.

[0029] Through the tilting setting and telescopic action of multiple No. 1 electric push rods 102, the angle adjustment of the mounting plate 201 in multiple directions can be achieved, thereby improving the flexibility of the jacking pipe installation. The coordinated work of multiple No. 1 electric push rods 102 ensures the smoothness and accuracy of the angle adjustment. Through the above-mentioned improvement measures, the performance of the power device for jacking pipes can be further improved, making it more flexible, stable and efficient in actual construction.

[0032] Furthermore, the clamping member 204 includes a fixing sleeve 205 correspondingly arranged on the left and right sides of the top of the mounting plate 201. The bottom of the inner wall of the fixing sleeve 205 fits the surface of the pipe to be used. The fixing sleeve 205 is close to each other and has multiple clamping plates 207 arranged in a circular array on one side. The multiple clamping plates 207 are slidingly connected to one side of the fixing sleeve 205, and the moving direction of the multiple clamping plates 207 is from the circumference of the fixing sleeve 205 to its center.

[0033] The design of the fixing sleeve 205 and the clamping plate 207 can flexibly adjust the clamping force and position to ensure that the jacking pipe is stably fixed at different angles. The use of the rubber pad 208 increases the friction during clamping to prevent the jacking pipe from sliding during construction. The combined design of the fixing sleeve 205 and the clamping plate 207 ensures that the jacking pipe is stably fixed at different angles, thereby improving construction quality and safety.

[0034] Furthermore, the outer walls of multiple clamping plates 207 are fixedly connected to the No. 3 electric push rod 206, and the No. 3 electric push rod 206 is fixedly connected to the movable plate 209 at one end away from the clamping plate 207. The multiple movable plates 209 are arranged in a circular array outside the circumference of the fixed sleeve 205 and are slidably connected to it. The moving direction of the multiple movable plates 209 is to slide from the circumference of the fixed sleeve 205 to its center.

[0035] The combination of the No. 3 electric push rod 206 and the movable plate 209 realizes the precise control of the clamping plate 207, improves the uniformity and stability of clamping, and especially realizes the precise control of the clamping plate 207 through the combined design of the No. 3 electric push rod 206 and the movable plate 209, ensures the stable fixation of the jacking pipe at different angles, and improves the construction quality and safety.

[0036] Furthermore, the inner walls of multiple movable plates 209 are threadedly connected with threaded rods 210, and the multiple threaded rods 210 are arranged in a circular array outside the fixed sleeve 205. The multiple threaded rods 210 are rotatably connected to the positioning frames 211 at one end away from the fixed sleeve 205, and the multiple positioning frames 211 are fixed in a circular array on the circumferential surface of the fixed sleeve 205.

[0037] Furthermore, the inner walls of the plurality of movable plates 209 are slidably connected to limit rods 212 , which are arranged in a circular array outside the fixing sleeve 205 , and are fixedly arranged between the fixing sleeve 205 and the positioning frame 211 .

[0038] The combination of threaded rod 210 and limiting rod 212 ensures stable movement of movable plate 209, further improving the precision and reliability of clamping. These improvements further enhance the performance of the pipe jacking power unit, making it more flexible, stable, and efficient during actual construction. In particular, the combined design of threaded rod 210 and limiting rod 212 ensures stable movement of movable plate 209, further improving the precision and reliability of clamping.

[0039] Furthermore, a plurality of threaded rods 210 are fixedly sleeved at one end away from the positioning frame 211 with a driven bevel gear 213, and the driven bevel gears 213 are arranged in a circular array on the side of the fixed sleeve 205 away from each other. The fixed sleeve 205 is rotatably connected to the side away from each other with a bevel gear ring 214, and the bevel gear ring 214 and the plurality of driven bevel gears 213 are meshed with each other. The surface of the bevel gear ring 214 is meshed with a driving bevel gear 215, and the circumferential surface of the fixed sleeve 205 is fixedly connected to a positioning plate 216, and the top of the positioning plate 216 is fixedly connected to a power motor 217, and the output end of the power motor 217 is fixedly connected to the inner wall of the driving bevel gear 215, and a protective cover 218 is provided on the outside of the power motor 217, and the bottom of the power motor 217 and the protective cover 218 are fixedly connected to the top of the positioning plate 216.

[0040] By starting the power motor 217, the power motor 217 drives the active bevel gear 215 to rotate. When the active bevel gear 215 rotates, it meshes with the bevel gear ring 214, which transmits the rotational power to the bevel gear ring 214. The bevel gear ring 214 rotates on the opposite side of the fixed sleeve 205. As the bevel gear ring 214 rotates, it drives multiple driven bevel gears 213 to rotate synchronously. The synchronous rotation of the multiple driven bevel gears 213 drives multiple threaded rods 210 to rotate synchronously. As the multiple threaded rods 210 rotate synchronously, they drive multiple moving plates 209 to rotate synchronously. The number three electric push rod 206, clamping plate 207, and rubber pad 208 move toward the center of the fixed sleeve 205 to effectively clamp the jacking pipe. These improvements further enhance the performance of the pipe jacking power unit, making it more flexible, stable, and efficient during actual construction. In particular, the combined design of the power motor 217, driving bevel gear 215, bevel gear ring 214, and driven bevel gear 213 enables synchronous control of multiple threaded rods 210, ensuring stable and precise movement of the clamping plate 207. This design not only meets the needs of diverse construction conditions but also significantly improves construction quality and safety.
