[0002] A transverse pipe section refers to a segmented pipe structure in various underground or surface pipeline systems that is arranged laterally relative to a specific reference direction (such as the axis of a building or the direction of a road). In the construction of urban underground infrastructure, such as underground drainage pipelines and integrated pipe corridors, the use of underground through-type pipe laying requires the use of related pipe jacking equipment.

[0003] In underground pipeline installations, pipe sections often lack effective support and guidance structures, and the friction between the pipe sections and the surrounding soil is high, resulting in significant pushing resistance. Furthermore, in long-distance pipe jacking construction, the lack of effective support and guidance can cause pipe sections to deviate from the design route, affecting the normal operation of the entire pipeline system. Therefore, it is necessary to provide an underground transverse pipe section jacking device that uses a steel structure guide base and rollers to support and guide the pipe sections, ensuring the accuracy of the jacking direction. At the same time, it adopts an expandable pushing frame structure to adapt to the pipe section pushing work of different pipe sections. Utility Model Content

[0022] In the following description, embodiments of the underground transverse pipe jacking device of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates an embodiment of an underground horizontal pipe jacking device, comprising a guide base 1; a hydraulic cylinder 2 is disposed on the right side of the guide base 1, and a stop 3 is disposed on the right side of the hydraulic cylinder 2, the stop 3 being laid at the bottom of the pit, the right side of the hydraulic cylinder 2 being tightly fitted to the inner wall of the stop 3; a push frame 4 is disposed on the right side of the top of the guide base 1, and a handle 8 is welded to the top of the push frame 4; a limiting groove 5 adapted to the push frame 4 is provided at the bottom of the inner cavity of the guide base 1; the output end of the hydraulic cylinder 2 is fixedly connected to the push frame 4 through a flange; and the front and rear sides of the push frame 4 are... Each component is equipped with an extension assembly 6, which includes extension arms 61 located on the front and rear sides of the push frame 4. A crank 62 is rotatably connected to the inner cavity of the extension arm 61. A threaded rod 63 is welded to the side of the crank 62 closest to the push frame 4. Threaded seats 64 are welded to both the front and rear sides of the push frame 4. The threaded rod 63 is threaded into the inner cavity of the threaded seat 64. The extension arm 61 is slidably connected to the inner cavity of the push frame 4. Through the arrangement of the extension assembly 6, the crank 62, threaded rod 63, and threaded seat 64 work together to adjust the position of the extension arm 61. The blocking area of ​​the pusher frame 4 is increased to adapt to the advancement of pipe sections with different diameters. Multiple support components 7 are provided on the front and rear sides of the top of the guide base 1. Each support component 7 includes a support frame 71. Multiple guide grooves 72 adapted to the support frame 71 are opened on the front and rear sides of the top of the guide base 1. Two threaded pins 74 are welded to the bottom of the inner cavity of the guide grooves 72. An arc-shaped hole 75 adapted to the threaded pin 74 is opened on the top of the support frame 71. Nuts 76 are threaded onto the surface of the threaded pins 74, and the nuts 76 are pressed against the support. The top of the support frame 71 is fixed by the use of threaded pin 74 and nut 76, which allows the support roller 73 to effectively support and guide the pipe section. At the same time, the use of threaded pin 74 and arc hole 75 allows the support frame 71 to slide back and forth on the top of the guide base 1, thereby adjusting the support position of the support roller 73 and supporting and guiding pipe sections of different sizes. The top of the support frame 71 is rotatably connected to the support roller 73, and the surface of the support roller 73 rolls in contact with the surface of the pipe section.

[0024] Working principle: When using this utility model, the user pre-dug an installation pit for the guide base 1 in the foundation pit, then placed the guide base 1 in the installation pit, placed the stop 3 in the foundation pit, and made the right side of the hydraulic cylinder 2 contact the inner wall of the stop 3, so that the output end of the hydraulic cylinder 2 is fixedly connected to the right side of the push frame 4 through the flange. The pipe section is then hoisted to the top of the guide base 1, so that the surface of the pipe section rolls into contact with the surface of the support roller 73. Then, the crank handle 62 is turned, and the crank handle 62 drives the threaded rod 63 to rotate during the rotation. As the screw rotates, the extension arm 61 slides out of the inner cavity of the pusher frame 4 under the cooperation of the threads on the surface of the threaded rod 63 and the threaded seat 64. Then, the hydraulic cylinder 2 is activated, and the hydraulic cylinder 2 pushes the pusher frame 4 to the left, so that the left side of the pusher frame 4 and the extension arm 61 contacts the pipe section and pushes the pipe section forward, thereby causing all pipe sections to shift to the left. After the single stroke of the hydraulic cylinder 2 is completed, the pusher frame 4 is retracted to the right by the hydraulic cylinder 2, and a new pipe section is hoisted in for continuous pipe jacking until the pipe section passes through the culvert.

[0025] In summary, this underground horizontal pipe jacking device, through the combined use of guide base 1 and support component 7, supports and guides the pipe section. At the same time, through the combined use of hydraulic cylinder 2, stop seat 3, push frame 4 and extension component 6, the pipe section is continuously advanced, thus achieving the purpose of low advancing resistance, labor-saving and convenient pipe jacking, and adjustable support and advancing dimensions.
