Description

Technical Field

[0001] This utility model relates to the field of pipe jacking machine technology, and in particular to a hydraulic pipe jacking device. Background Technology

[0002] Hydraulic pipe jacking equipment, the core equipment in pipe jacking construction, is called a pipe jacking machine. It uses a hydraulic system to drive cylinders to generate thrust, cutting the soil while jacking the pipe, achieving trenchless pipe laying. The auger excavator, the core device for discharging excavated soil, is located behind the cutterhead at the front of the pipe jacking machine. It is connected to the cutting chamber and runs through the main unit, extending to the excavation outlet of the working shaft. It plays a crucial role in soil transportation, earth pressure control, and seepage prevention and pressure maintenance, highly meeting the current construction needs of pipe jacking machines. Currently, during some shallow pipe jacking operations, if the jacking process encounters miscellaneous fill and boulders on the riverbank, the construction personnel need to remove the auger excavator to clear the boulders. If the riverbank cracks due to settlement, river water can seep in and cause piping. In pipe jacking machine rescue scenarios, if lifting equipment is not deployed in advance, the search for equipment can easily delay rescue efforts, leading to the pipe jacking machine being completely submerged and damaged. Utility Model Content

[0003] The purpose of this invention is to address the problem that when using shallow pipe jacking machines, the auger needs to be disassembled when encountering mixed fill and boulders. However, if riverbank subsidence causes piping, and there is a lack of lifting equipment for rescue, the rescue opportunity may be delayed due to the search for equipment, leading to damage to the machine. Therefore, a hydraulic pipe jacking device is proposed.

[0004] The technical solution of this utility model is as follows: a hydraulic pipe jacking device, including a pipe jacking machine base, and further including: a support plate fixedly connected to one end of the pipe jacking machine base, a clamping plate movably connected to the support plate, and support blocks fixedly connected to both ends of the clamping plate; a bracket mechanism slidably arranged on the support blocks; and a lifting mechanism installed on the bracket to move the pipe jacking machine base upward.

[0005] Optionally, the support mechanism includes a pair of limiting grooves formed on the support block, a sliding clamp is slidably connected to the support block through the limiting grooves, limiting sliders that are engaged in the limiting grooves are fixedly connected to both ends of the sliding clamp, a support frame is fixedly connected to the upper surface of the middle part of the sliding clamp, and a support plate is fixedly connected to the top of the support frame.

[0006] Optionally, the lifting mechanism includes a chain hoist fixedly connected to the lower surface of the middle part of the pallet. Multiple support chains are hung at the bottom of the chain hoist, and hooks are fixedly connected to the bottom ends of the support chains. A pair of hanging rings corresponding to the hooks are fixedly connected to the outer walls of both sides of the jacking machine base.

[0007] Optionally, the sliding clamp is spirally connected with a locking bolt whose end abuts against the upper surface of the support block.

[0008] Optionally, the card plate is provided with multiple fixing screw holes, and the abutment plate is provided with multiple fixing bolts whose ends are spirally connected to the fixing screw holes.

[0009] Optionally, the sliding clamp is provided with a reinforcing rod, one end of which is fixedly connected to the upper surface of the sliding clamp, and the other end of which is fixedly connected to the outer wall of the corresponding support frame.

[0010] Optionally, both ends of the card plate are provided with slots for the support frame to be inserted.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] In this embodiment, the hydraulic pipe jacking device utilizes a combination of components such as a support plate, a clamping plate, a support block, a bracket mechanism, and a lifting mechanism. When using the hydraulic pipe jacking device, the fixing bolts are removed to allow the support plate and clamping plate to move. After the sliding clamping plate is adjusted and fixed, the chain hoist connects to the pipe jacking machine base via a support chain and hooks. This method, through the integrated lifting mechanism, allows the pipe jacking machine base to be removed from the shallow well, thereby preventing delays in rescue efforts due to searching for lifting equipment and avoiding damage from flooding of the pipe jacking machine.

[0023] Example

[0024] like Figures 1 to 3As shown, this utility model proposes a hydraulic pipe jacking device, including a pipe jacking machine base 1. A support plate 11 is fixedly connected to one end of the pipe jacking machine base 1, and the support plate 11 is movably connected to a clamping plate 2, providing a connection base. The clamping plate 2 is movably connected to the support plate 11, and the clamping plate 2 is movably connected to the support plate 11. Support blocks 21 are fixed at both ends for supporting the support mechanism. The clamping plate 2 is fixedly connected to the inner wall of the working shaft. Slots 23 for the support frame 24 to be inserted are provided at both ends of the clamping plate 2, and the slots 23 are located at both ends of the clamping plate 2 for inserting the support frame 24, thus positioning the support frame 24. Support blocks 21 are fixedly connected to both ends of the clamping plate 2; a support mechanism is slidably mounted on the support block 21; and a lifting mechanism that moves the pipe jacking machine base 1 upwards is installed on the support.

[0025] Among them, such as Figures 1 to 2 As shown, the support mechanism includes a pair of limiting grooves 22 formed on the support block 21. The limiting grooves 22 cooperate with the limiting sliders 31 to restrict the sliding direction of the sliding clamp 3. The sliding clamp 3 is slidably connected to the support block 21 through the limiting grooves 22. The sliding clamp 3 slides within the limiting grooves 22 via the limiting sliders 31, and is used to install the support frame 24 and adjust its position. A locking bolt 32 with its end abutting against the upper surface of the support block 21 is screwed onto the sliding clamp 3. The locking bolt 32 slides within the limiting grooves 22 via the limiting sliders 31, and is used to install the support frame 24 and adjust its position. Limiting sliders 31 that engage with the limiting grooves 22 are fixedly connected to both ends of the sliding clamp 3. The limiting sliders 31 are fixed to both ends of the sliding clamp 3 and engage with the limiting grooves 22, allowing the sliding clamp 3 to slide within the limiting grooves 22. A support frame 24 is fixedly connected to the upper surface of the middle part of the sliding clamp 3, and a support plate 25 is fixedly connected to the top of the support frame 24.

[0026] In addition, such as Figures 1 to 2 As shown, the lifting mechanism includes a chain hoist 26 fixedly connected to the lower surface of the middle part of the support plate 25. The chain hoist 26 can be operated electrically or manually as needed, and it is fixed to the lower surface of the support plate 25 to tighten the support chain 27, thereby driving the pipe jacking machine base 1 to move upward. Multiple support chains 27 are hung at the bottom of the chain hoist 26, with hooks 28 connected to their bottom ends for transmitting tension. Support chains 27 of appropriate length can be used as needed to ensure that the pipe jacking machine base 1, when raised to its limit, is completely detached from the working shaft. Hooks 28 are fixedly connected to the bottom ends of the support chains 27, and the hooks 28 are fixed to the bottom ends of the support chains 27 and connected to hanging rings 12, thus connecting the support chains 27 to the pipe jacking machine base 1. A pair of hanging rings 12 corresponding to the hooks 28 are fixedly connected to the outer walls of both sides of the pipe jacking machine base 1.

[0027] It is worth noting that, such as Figure 1 and Figure 3As shown, the card plate 2 has multiple fixing screw holes 201. These fixing screw holes 201 are formed on the card plate 2 and cooperate with the fixing bolts 13 to achieve a fixed connection between the card plate 2 and the support plate 11. The support plate 11 has multiple fixing bolts 13, the ends of which are screwed to the fixing screw holes 201. The fixing bolts 13 pass through the fixing screw holes 201 on the card plate 2 and connect to the support plate 11 to achieve a fixed connection between the card plate 2 and the support plate 11.

[0028] Furthermore, such as Figures 1 to 2 As shown, a reinforcing rod 29 is provided on the sliding clamp 3. The reinforcing rod 29 connects the sliding clamp 3 and the support frame 24, enhancing the structural stability of the support mechanism. One end of the reinforcing rod 29 is fixedly connected to the upper surface of the sliding clamp 3, and the other end of the reinforcing rod 29 is fixedly connected to the outer wall of the corresponding support frame 24.

[0029] In this embodiment, when using the hydraulic pipe jacking device, the fixing bolt 13 is first removed from the fixing screw hole 201 on the clamping plate 2 by fixing and disassembling the fixing bolt 13. At this time, the abutment plate 11 and the clamping plate 2 can be movably set. Then, the sliding clamping plate 3 slides in the limiting slide groove 22 through the limiting slider 31, so that the sliding clamping plate 3 drives the support frame 24 on it to be adjusted to a suitable position on the support block 21. Then, the locking bolt 32 is tightened to abut against the upper surface of the support block 21 for fixation. Next, the chain hoist 26 is fixed to the lower surface of the support plate 25, and the hook 28 at the end of the support chain 27 is hung on the hanging ring 12. Then, the support chain 27 is tightened by the chain hoist 26, which can drive the pipe jacking machine base 1 to move upward, so that the pipe jacking machine base 1 can be dislodged from the shallow working well. In this way, the pipe jacking machine base 1 will not be submerged when the working well is flooded, which is convenient and quick.

[0030] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
