DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] In order to solve the technical problem that different trough blocks need to be replaced when constructing pipes with different diameters, which leads to low overall construction efficiency, the utility model provides a pipe jacking machine that can improve the overall construction efficiency without replacing supporting components.

[0024] It should be noted that the pipe jacking machine described in the utility model is used for but not limited to pipe jacking machines, etc. For the convenience of explanation, in the utility model, only a pipe jacking machine applied to a pipe jacking machine is used as an example for explanation, and the principle of a pipe jacking machine applied to other types of equipment is essentially the same as the principle applied to the pipe jacking machine, which will not be repeated here.

[0025] See also Figure 1 , Figure 1 It is a structural schematic diagram of a pipe jacking machine in one embodiment of the utility model, a pipe jacking machine includes a base 1, a propulsion device 2 and a support device 3, the propulsion device 2 is installed at one end of the base 1, and a slide groove 11 is provided at the other end of the base 1, and the length direction of the slide groove 11 is perpendicular to the axial direction of the propulsion device 2, the support device 3 includes a pair of cylinders 31 and a driving member 33, the two cylinders 31 are relatively installed on both sides of the axial direction of the propulsion device 2, and the fixed ends of the two cylinders 31 are slidably embedded in the slide groove 11, and the driving member 33 is used to drive the two cylinders 31 to move toward or away from each other.

[0026] In this embodiment, by setting up a pair of cylinders 31 and a driving member 33, when the supporting device 3 needs to support pipes of different diameters, the supporting device 3 can support pipes of different diameters by moving the two cylinders 31 relative to or toward each other and by synchronously lifting and lowering the two cylinders 31. There is no need to replace the supporting device 3 that is compatible with the pipe, which effectively improves the overall construction efficiency.

[0027] First, the bottom of the base 1 is fixedly connected to the ground; secondly, one end of the pipeline is connected to the propulsion device 2, and the side wall of the pipeline is placed on the movable ends of the two cylinders 31; then, the driving member 33 is started, so that the two cylinders 31 are moved to the appropriate position; then, the two cylinders 31 are raised and lowered synchronously until the pipeline and the propulsion device 2 are coaxial; finally, the propulsion device 2 is started, and the pipeline moves in a preset direction under the action of the propulsion device 2.

[0028] Furthermore, the two cylinders 31 are operated synchronously through a PLC control terminal.

[0029] In one embodiment, see Figure 1 The supporting device 3 also includes a screw rod 32, which is rotatably connected to the slide groove 11. The fixed ends of the two cylinders 31 are provided with threaded holes 311, and the two threaded holes 311 are threadedly connected to the screw rod 32, and the thread directions of the two threaded holes 311 are opposite. The driving member 33 is used to drive the screw rod 32 to rotate and make the two cylinders 31 move toward or away from each other.

[0030] In this embodiment, the two threaded holes 311 are arranged on the screw rod 32 in opposite directions, so that when the screw rod 32 rotates, it can drive the two cylinders 31 to move relative to or towards each other, so as to support the outer walls of pipes with different diameters.

[0031] Furthermore, the cross section of the slide groove 11 is square, and the cross section of the fixed end of the cylinder 31 is also square, so that when the screw rod 32 rotates, the two cylinders 31 can be driven to move along the length direction of the slide groove 11.

[0032] In one embodiment, see Figure 1 The movable ends of the two cylinders 31 are fixedly connected with support rods 312, and the length direction of the support rods 312 is the same as the propulsion direction of the propulsion device 2.

[0033] In this embodiment, the opposite side walls of the two support rods 312 are used to support the side walls of the pipeline. The function of the support rods 312 is to increase the contact area between the active end of the cylinder 31 and the side wall of the pipeline, so that the supporting effect is more stable.

[0034] Furthermore, the support rod 312 can also be rotatably connected to the movable end of the cylinder 31, so that when the motor 24 drives the pipeline to rotate, the support rod 312 can rotate along with the pipeline, effectively reducing the friction between the pipeline and the support rod 312.

[0035] In one embodiment, see Figure 1 A pressure plate 12 is fixedly connected to the end of the base 1 opposite to the slide groove 11.

[0036] In this embodiment, the function of the pressure plate 12 is to bear the reaction force generated when the propulsion device 2 pushes the pipeline. The pressure plate 12 then transmits the reaction force to the inner wall of the pit. The pressure plate 12 effectively increases the contact area between the pressure plate 12 and the inner wall of the pit, disperses the reaction force, and makes the utility model more stable.

[0037] In one embodiment, see Figure 1 The propulsion device 2 includes a hydraulic cylinder 21, a base 22, a connecting seat 23 and a motor 24. The fixed end of the hydraulic cylinder 21 is fixedly connected to the pressure plate 12, the base 22 is fixedly connected to the movable end of the hydraulic cylinder 21, the connecting seat 23 is fixedly connected to the end of the base 22 away from the pressure plate 12, and the motor 24 is fixedly connected to the end of the base 22 facing the pressure plate 12. The motor 24 is used to drive the connecting seat 23 to rotate.

[0038] In this embodiment, the connecting seat 23 is used to support one end of the pipe, the side wall of the pipe is supported by the supporting device 3, and the other end of the pipe is inserted into the pre-buried position. The function of the motor 24 is to drive the connecting seat 23 to rotate. When the hydraulic cylinder 21 pushes the base 22 to move toward the pre-buried position, the connecting seat 23 pushes the pipe into the pre-buried position.

[0039] In one embodiment, see Figure 1 The top of the base 1 is fixedly connected with a slideway 13, and the bottom of the base 22 is slidably embedded in the slideway 13.

[0040] In this embodiment, the function of the slide 13 is, on the one hand, to prevent the base 22 from being suspended in the air, support the base 22, and relieve the force on the hydraulic cylinder 21; on the other hand, to ensure the moving direction of the base 22, and the base 22 cannot be separated from the slide 13, so that the thrust direction generated by the propulsion device 2 is more stable.

[0041] In one embodiment, see Figure 1 There are two hydraulic cylinders 21, which are located on opposite sides of the motor 24. The opposite ends of the base 22 are fixedly connected with a propulsion plate 221. The fixed ends of the two hydraulic cylinders 21 are fixedly connected to the pressure plate 12, and the movable ends of the two hydraulic cylinders 21 are fixedly connected to the propulsion plate 221 respectively.

[0042] In this embodiment, the two hydraulic cylinders 21 are operated synchronously through the PLC control end. The two hydraulic cylinders 21 act on the propulsion plates 221 at the opposite ends of the base 22 respectively, so that the force on the base 22 is more stable, thereby enhancing the thrust of the propulsion device 2 on the pipeline and improving the construction efficiency.

[0043] In one embodiment, see Figure 1 A level 222 is fixedly connected to the top of the base 22 .

[0044] In this embodiment, the role of the level meter 222 is to facilitate construction personnel to determine whether the device is in a horizontal state through the level meter 222, so as to facilitate the advancement of the pipeline.

[0045] In one embodiment, see Figure 1 A reinforcement rod 14 is fixedly connected to the middle of the base 1.

[0046] In this embodiment, the function of the reinforcement rod 14 is to improve the stability of the base 1 and alleviate the vibration generated by the pipeline during the advancement process, which will reduce the service life of the base 1.

[0047] In one embodiment, see Figure 1 A supporting foot 15 is fixedly connected to the bottom of the base 1.

[0048] In this embodiment, the function of the support foot 15 is to improve the stability of the device. A cone is fixedly connected to the bottom of the support foot 15, so that the support foot 15 can be inserted into the ground through the cone, so that the base 1 is fixed. When the base 1 needs to be leveled, the support foot 15 with a lower horizontal position can be raised. After the cone is inserted into the soil, it is raised between the support foot 15 and the ground.

[0049] Furthermore, the support foot 15 can also be installed with a lifting member, for example, the support foot 15 is provided with a threaded hole, a screw is connected to the threaded hole, and the support foot 15 is lifted and lowered by rotating the screw, thereby achieving the leveling of the base 1.

[0050] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0051] First, the pressure plate 12 is close to the inner wall of the pit, and the supporting foot 15 is fixedly connected to the bottom of the pit. The horizontal adjustment of the base 1 is completed by leveling the supporting foot 15, so that the connecting seat 23 is coaxial with the embedded position; secondly, one end of the pipeline is connected to the connecting seat 23, and the side wall of the pipeline is placed on two supporting rods 312, and the other end of the pipeline faces the embedded position; then, the driving member 33 is started, and the screw 32 is rotated, so that the two cylinders 31 move to the appropriate position. At the same time, the two cylinders 31 are raised and lowered synchronously until the pipeline, the connecting seat 23 and the embedded position are coaxial; finally, the hydraulic cylinder 21 is started, and the base 22 drives the pipeline to be inserted into the embedded position under the action of the hydraulic cylinder 21. When facing pipelines of different diameters that need to be supported, the supporting device 3 can support pipelines of different diameters by moving the two cylinders 31 relative or toward each other and lifting the two cylinders 31 synchronously. There is no need to replace the supporting device 3 that is compatible with the pipeline, which effectively improves the overall construction efficiency.
