Description

Technical Field

[0001] The utility model relates to a plugging device for pipe jacking construction, belonging to the technical field of pipe jacking construction. Background Art

[0002] Pipe jacking construction is a method of underground pipeline construction that does not require excavation of the surface layer and can pass through roads, railways, ground buildings and underground pipelines. With the continuous development of pipe jacking, pipe jacking construction technology has gradually developed into a trenchless construction technology based on air pressure balance, mud water balance and earth pressure balance. At present, pipe jacking construction technology has become a conventional construction method adopted. Many pipelines such as water pipes, gas pipes, power cables, communication cables and power plant circulation systems also use pipe jacking construction technology.

[0003] A Chinese patent publication (publication number: CN 219994560 U) discloses a pipe jacking construction plugging device, which relates to the field of pipe jacking construction, including a support ring, wherein the upper and lower ends of the inner side of the support ring are provided with a slot, and the inner side of the support ring is movably connected with a support plate, and the upper and lower ends of the support plate are fixedly connected with a protrusion, and the protrusion is located inside the slot, and the rear end of the inner side of the support ring is fixedly connected with a retaining ring. The utility model inserts the support plate into the support ring, and drives the screw to rotate by turning the hand wheel to drive the support pad to move to the rear side, and the support pad pushes the support plate to the rear side as the screw moves inward, so that the support plate and the protrusion slide to the rear side along the inside of the support ring, and the support plate and the protrusion are abutted against the front side of the retaining ring and abutted and tightened with the force of the screw, so as to facilitate plugging. At the same time, when the head of the tunnel boring machine is drilled out, the support plate can be removed by reverse operation, so that the effect of multiple uses can be achieved, and the economy is improved;

[0004] Although the above-mentioned device can be reused by disassembling the support plate, it is rather cumbersome to disassemble or install each time, and different hand wheels need to be turned multiple times to release the support pad from squeezing the support plate. Each installation or disassembly consumes a lot of time and labor costs. At the same time, since the support plate of the above-mentioned device is composed of two pieces, and the support ring can be sealed by splicing the two support plates, there is still a gap between the two support plates, which makes the overall sealing effect worse, which may affect the subsequent normal use.

[0005] Therefore, a plugging device for pipe jacking construction is proposed. Utility Model Content

[0006] In view of this, the utility model provides a plugging device for pipe jacking construction to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0010] Further preferably, slide grooves are provided on the left and right sides of the inner cavities of the four box bodies, and the outer sides of the four sliding blocks are slidably connected to the inner cavities of the eight slide grooves.

[0011] Further preferably, the inner sides of the inner cavities of the four box bodies (201) are each provided with a slot (213), and the eight insert blocks (218) each penetrate the inner cavities of the eight slots (213) and extend to the inner side of the mounting ring (1).

[0012] Further preferably, the tops of the four box bodies are each provided with a sliding groove, and the four sliding blocks each penetrate the inner cavities of the four sliding grooves and extend to the tops of the four box bodies.

[0013] Further preferably, clamping blocks are fixedly installed around the top of the support ring, and the four clamping blocks are clamped in the inner cavities of the four clamping slots.

[0014] Further preferably, a moving groove is provided at the top of the mounting ring, and moving blocks are fixedly installed around the bottom of the turntable, and the four moving blocks are slidably connected to the inner cavity of the moving groove.

[0015] Further preferably, a circular ring is fixedly mounted on the outer side of the mounting ring, and mounting bolts are threadedly connected around the top of the circular ring.

[0016] Further preferably, the eight slots and the eight jacks are in the same horizontal direction, and the eight slots and the eight jacks are interconnected.

[0017] Further preferably, the sizes of the eight plug blocks match the sizes of the eight slots and the eight plug holes, and the eight plug blocks all pass through the inner cavities of the eight slots and are plugged into the inner cavities of the eight plug holes.

[0018] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0019] 1. The utility model provides a blocking mechanism. When the mounting ring needs to be blocked, the blocking block is placed on the top of the supporting ring and is connected to the inner cavity of the card slot through the card block. Then the pull rod is pulled, and the pull rod drives the turntable to rotate. Due to the rotation of the turntable, the position of the adjusting slot changes, and the connecting rod is pulled inward to move synchronously. As the connecting rod moves, the connecting rod drives the sliding block to move inward synchronously, and when the sliding block moves, it also drives the slider and the plug block to move inward. At this time, the plug block is plugged into the inner cavity of the socket, and then the fixing bolt is rotated to make it threadedly connected to the inner cavity of the mounting block, so as to complete the installation of the blocking block. The installation method is relatively convenient, which can effectively save the time spent on each installation or disassembly of the blocking device, and also saves a lot of labor costs, thereby improving the efficiency and convenience of installing or disassembling the blocking device.

[0020] Second, the utility model can connect the mounting block and the fixing block to each other by setting a fixing bolt, thereby preventing the turntable from rotating by itself, thereby affecting the fixing effect of the blocking block; by setting a sliding groove, the moving direction of the slider can be limited, preventing the slider from deviating when moving, thereby affecting the installation or removal of the blocking block; by setting a slot, the moving direction of the plug-in block can be limited, preventing the plug-in block from deviating when moving, resulting in the inability to install or remove the blocking block; by setting a sliding groove, the moving direction of the sliding block can be limited, effectively preventing the possibility of the sliding block from deviating when moving, thereby affecting the fixing of the blocking block; by setting a clamping block, the blocking block can be clamped , so that the jack and the slot can be in the same horizontal direction, which is convenient for the plug-in work of the plug-in block. By setting the movable groove and the movable block, the turntable can be supported and the direction of its rotation can be limited to prevent the turntable from offsetting when rotating, thereby affecting the fixing effect of the blocking block. By setting the ring and the mounting bolts, the overall installation or disassembly of the equipment can be convenient, and the stability of the equipment during installation is improved to prevent the overall shaking of the equipment due to interference from external factors. By setting the jack and the slot, since the two are in the same horizontal direction, the plug-in block can be moved freely. By setting the jack, the slot and the plug-in block, since the sizes of the three match each other, the stability of the plug-in block after being plugged into the jack can be improved.

The eight slots 213 and the eight sockets 4 are in the same horizontal direction, and the eight slots 213 and the eight sockets 4 are interconnected. The sizes of the eight plug blocks 218 match the sizes of the eight slots 213 and the eight sockets 4. The eight plug blocks 218 all pass through the inner cavities of the eight slots 213 and are plugged into the inner cavities of the eight sockets 4.

[0038] By providing a fixing bolt 211, the mounting block 210 and the fixing block 209 can be connected to each other, thereby preventing the turntable 206 from rotating on its own, thereby affecting the fixing effect of the blocking block 3.

By providing a slot 213, the moving direction of the plug-in block 218 can be limited to prevent the plug-in block 218 from deviating when moving, resulting in the inability to install or remove the blocking block 3. By providing a sliding groove 214, the moving direction of the sliding block 204 can be limited to effectively prevent the possibility of the sliding block 204 deviating when moving, thereby affecting the fixing of the blocking block 3. By providing a clamping block 215, the blocking block 3 can be clamped. , so that the jack 4 and the slot 213 can be in the same horizontal direction, which is convenient for the plug-in work of the plug-in block 218.

By setting the ring 7 and the mounting bolt 8, the overall installation or disassembly of the equipment can be convenient, and the stability of the equipment during installation is improved to prevent the overall shaking of the equipment due to interference from external factors. By setting the jack 4 and the slot 213, since the two are in the same horizontal direction, the plug-in block 218 can be moved freely.

At this time, the pull rod 208 drives the turntable 206 to rotate, and due to the rotation of the turntable 206, the position of the adjustment slot 207 changes, and the connecting rod 205 is pulled inward to move synchronously. With the movement of the connecting rod 205, the connecting rod 205 drives the sliding block 204 to move inward synchronously, and when the sliding block 204 moves, it also drives the slider 203 and the plug block 218 to move inward. At this time, the plug block 218 is plugged into the inner cavity of the socket 4, and then the fixing bolt 211 is rotated to make it threadedly connected to the mounting block 2 10, the installation of the blocking block 3 is completed. When the blocking block 3 needs to be disassembled, the fixing bolt 211 is screwed to make the mounting block 210 and the fixing block 209 contact and limit the position. Then the pull rod 208 is grasped and rotated, thereby driving the turntable 206 to rotate in the opposite direction. At this time, due to the change in the position of the adjusting groove 207, the adjusting groove 207 pushes the connecting rod 205 outward to move. The connecting rod 205 simultaneously drives the sliding block 204, the slider 203 and the plug block 218 to move outward synchronously, so that the plug block 218 is moved out of the inner cavity of the socket 4, the limiting work of the socket 4 is released, and then the socket 4 is taken out from the inner side of the mounting ring 1, thereby completing the disassembly of the blocking block 3.
