DETAILED DESCRIPTION

[0026] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0027] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] Embodiment 1

[0029] The embodiment provides a pipe jacking machine for pipe gallery construction, specifically as shown in the drawings, comprising a mounting frame 1, a stabilizing foot 2, a pipe jacking machine body 4, the stabilizing foot 2 is mounted on the mounting frame 1 to stabilize the mounting frame 1, preventing the mounting frame 1 from moving during operation, the mounting frame 1 is used to carry the pipe jacking machine body 4, the pipe jacking machine body 4 is used for pipe jacking operation, the pipe jacking machine body 4 is a commercially available device, and the specific structure and working principle are clear to those skilled in the art, and the pipe jacking machine body 4 is not the specific improvement point of the present application, and will not be described here. Figures 1-6 The mounting frame 1 comprises a base 101 and a side support 102 fixed on the base 101, and further comprises an adjusting assembly 3, the adjusting assembly 3 comprises two groups of symmetrically arranged adjusting parts, the adjusting part comprises an adjusting unit and a connecting frame 308, two telescopic rods 306 are connected to the connecting frame 308 through a spherical pair, the pipe jacking machine body 4 is connected to the telescopic rod 306 through a spherical pair; the adjusting unit is used to control the connecting frame 308 to move longitudinally and transversely.

[0030] Specifically, when the connecting brackets 308 on the two adjustment units run in the same direction, the longitudinal height or lateral position of the pipe jacking machine body 4 is finely adjusted. The purpose of height adjustment is to make the height of the pipe axis on the pipe jacking machine body 4 the same as the height of the pipe axis of the underground preset path. Similarly, the lateral position adjustment is also to make the position of the pipe axis on the pipe jacking machine body 4 the same as the position of the pipe axis of the underground preset path. The positional accuracy of the pipe jacking machine body 4 is improved through dual lateral and longitudinal adjustments. If there is a deviation in the installation of the mounting bracket 1, causing a deviation between the pipe axis on the pipe jacking machine body 4 and the pipe axis of the preset path, then the connecting brackets 308 on the two adjustment units are made to run horizontally but in opposite directions, and the lateral deviation angle of the pipe jacking machine body 4 is finely adjusted until the pipe axis on the pipe jacking machine body 4 coincides with the pipe axis of the preset path. If the preset path is not horizontal, then the connecting brackets 308 on the two adjustment units are made to run vertically but in opposite directions, and the longitudinal deviation angle of the pipe jacking machine body 4 is finely adjusted until the pipe axis on the pipe jacking machine body 4 coincides with the pipe axis of the preset path.

[0031] By setting up an adjustment unit, even if there is a deviation in the installation position of the mounting bracket 1, there is no need to reinstall it. The longitudinal height, tilt angle or lateral position and lateral deflection angle of the pipe jacking machine body 4 can be adjusted by simply adjusting the adjustment unit. This simplifies the installation steps of the pipe jacking machine body 4, reduces the installation requirements of the pipe jacking machine body 4, and greatly improves the work efficiency.

[0032] Example 2:

[0033] This embodiment further expands the adjustment section based on the above embodiment, specifically as follows: Figures 5-6 As shown, the adjustment unit includes a drive group and a moving group. The moving group includes a transverse sliding frame 309, which is slidably connected to the mounting frame 1. A longitudinal sliding frame 305 is slidably connected to the transverse sliding frame 309. The sliding direction of the longitudinal sliding frame 305 is perpendicular to the sliding direction of the transverse sliding frame 309. A connecting frame 308 is mounted on the longitudinal sliding frame 305. The drive group is used to drive the transverse sliding frame 309 to move laterally and drive the longitudinal sliding frame 305 to move vertically.

[0034] The driving group comprises a first motor 301, a first worm 302, a second motor 303 and a second worm 304, the first motor 301 and the second motor 303 are fixed on the side support 102, the first worm 302 and the second worm 304 are rotatably connected on the side support 102, the first worm 302 is installed on the output end of the first motor 301, the second worm 304 is installed on the output end of the second motor 303, the first motor 301 and the second motor 303 are of the same specification, and the first worm 302 and the second worm 304 are also of the same specification; the driving group further comprises a gear 307 and a worm wheel 310, the gear 307 is fixedly connected with the worm wheel 310, the worm wheel 310 is engaged with the first worm 302 and the second worm 304 respectively, and a rack 311 is arranged on the longitudinal sliding frame 305, and the gear 307 is engaged with the rack 311.

[0035] When the first worm 302 and the second worm 304 rotate in the same direction, the first worm 302 and the second worm 304 jointly drive the worm wheel 310 to rotate, the worm wheel 310 drives the gear 307 to rotate synchronously, and when the gear 307 rotates, the longitudinal sliding frame 305 is driven to move longitudinally on the transverse sliding frame 309 through the rack 311, so as to realize the height adjustment of the pipe jacking machine body 4, and when the first worm 302 and the second worm 304 stop rotating, the longitudinal sliding frame 305 will be driven to fall due to the gravity of the pipe jacking machine body 4, that is, the rack 311 will have a tendency to drive the gear 307, but due to the self-locking effect of the worm wheel 310 and the first worm 302 and the second worm 304, the position of the pipe jacking machine body 4 can be kept stable.

[0036] When the first worm 302 and the second worm 304 rotate in different directions, the first worm 302 and the second worm 304 cannot drive the worm wheel 310 to rotate, and at this time the worm wheel 310 will drive the transverse sliding frame 309 to move transversely on the side support 102, so as to realize the transverse position adjustment of the pipe jacking machine body 4.

[0037] Through the above setting, the transverse and longitudinal displacement of the connecting frame 308 can be controlled by only the first worm 302 and the second worm 304, and the position of the pipe jacking machine body 4 can be kept stable through the self-locking effect of the worm wheel 310 and the first worm 302 and the second worm 304.
