Description

Technical Field

[0001] This utility model belongs to the field of pipe jacking construction technology, specifically a main jacking device for pipe jacking construction. Background Technology

[0002] Pipe jacking, also known as trenchless construction, is a pipeline laying technology that involves little or no excavation. It is mainly used in industries such as rainwater, sewage, and power. The main principle of pipe jacking is to use the jacking force generated by the jacking equipment in the foundation pit to overcome the friction between the pipeline and the surrounding soil, and to push the pipeline into the soil at the designed slope.

[0003] In actual operation, the main jacking equipment is usually installed in the foundation pit and is basically directly exposed to the open environment. This causes some stones or sand to fall through the foundation pit onto the output shaft surface of the hydraulic push rod in the main jacking device, thus causing damage and affecting its service life. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a main jacking device for pipe jacking construction, which solves the problem that some stones or sand can easily fall through the foundation pit onto the output shaft surface of the hydraulic push rod in the main jacking device, thereby causing damage and affecting the service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a main jacking device for pipe jacking construction, comprising a base, a connecting hole on the top of the base, a support frame connected to the base, a fixing plate connected to the support frame, connecting grooves on both sides above the support frame, a worktable connected to the support frame, a guide groove on the worktable, a motor installed on one side of the worktable, a threaded rod connected to the output shaft of the motor, and two moving blocks installed on the threaded rod;

[0006] Mounting brackets are connected above and below the movable block. Hydraulic push rods are mounted on the mounting brackets. A hollow plate is slidably mounted on the support frame through a connecting groove. Connecting strips are connected to the lower two sides of the hollow plate. A movable plate is slidably connected inside the hollow plate. A connecting plate is connected to the hollow plate. Insert rods are slidably connected to both sides of the connecting plate. A pull plate is connected to one end of each insert rod.

[0007] As a further embodiment of this utility model: the threaded rod is rotatably connected in the guide groove, and the two ends of the threaded rod are provided with threads in opposite directions.

[0008] As a further embodiment of this utility model: a threaded sleeve is installed on the movable block, the threaded sleeve is threadedly engaged with the threaded rod, and the movable block slides in the guide groove and contacts the groove wall.

[0009] As a further embodiment of this utility model: telescopic rods are rotatably connected to both sides of the movable plate, and one end of the telescopic rod is inserted into the connecting hole.

[0010] As a further embodiment of this utility model: a spring is sleeved on the insertion rod, one end of the spring is connected to the connecting plate, and the other end of the spring is connected to the pull plate.

[0011] As a further embodiment of this utility model: the fixing plate has insertion holes on both sides, the insertion rod is inserted into the insertion holes, and the connecting strip is T-shaped and slidably connected to the connecting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The main jacking equipment for pipe jacking construction is equipped with connecting strips, connecting grooves, hollow plates, movable plates, telescopic rods, pull plates, springs, insertion rods, and insertion holes. Workers push the connecting strips into the connecting grooves, allowing the hollow plates to be combined with the support frame. Then, the pull plate pulls the insertion rod to slide on the connecting plate. At this time, the spring is stretched by the pull plate, and the spring's rebound pushes the insertion rod into the insertion hole, fixing the hollow plate to the support frame and preventing slippage. Then, the movable plate is pulled to move, and one end of the telescopic rod is inserted into the connecting hole. This allows the hollow plates and movable plates to block the area above the hydraulic push rod, preventing falling objects from damaging the hydraulic push rod.

[0014] 2. The main jacking equipment for pipe jacking construction consists of a motor, threaded rod, moving block, threaded sleeve, mounting frame, and hydraulic push rod. The operator starts the motor to drive the threaded rod to rotate. The threaded engagement between the threaded sleeve and the threaded rod allows the moving block to move along the threaded rod in the guide groove. The moving block, in turn, drives the mounting frame to move, thereby adjusting the distance between multiple hydraulic push rods. This allows the hydraulic push rods to push pipes of different diameters, improving applicability. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a main jacking device for pipe jacking construction, including a base 1, a connecting hole 2 on the top of the base 1, a support frame 3 connected to the base 1, a fixing plate 4 connected to the support frame 3, insertion holes 22 on both sides of the fixing plate 4, insertion rods 17 being inserted into the insertion holes 22, and a connecting strip 14 having a T-shaped design and slidingly connected to a connecting groove 5. By sliding the connecting strip 14 in the connecting groove 5, workers can quickly complete the positioning and installation of the hollow plate 13, while the insertion of the insertion rod 17 into the insertion hole 22 can fix the hollow plate 13 and prevent the hollow plate 13 from sliding and falling.

[0023] Connecting slots 5 are provided on both sides above the support frame 3. A worktable 6 is connected to the support frame 3. A guide slot 7 is provided on the worktable 6. A motor 8 is installed on one side of the worktable 6. The output shaft of the motor 8 is connected to a threaded rod 9. The threaded rod 9 is rotatably connected in the guide slot 7. The two ends of the threaded rod 9 are provided with threads in opposite directions. Through the threads in opposite directions at the two ends of the threaded rod 9, the two moving blocks 10 can be driven to move in opposite directions when the threaded rod 9 rotates, thereby adjusting the distance between multiple hydraulic push rods 12.

[0024] Two movable blocks 10 are installed on the threaded rod 9. Threaded sleeves 19 are installed on the movable blocks 10. The threaded sleeves 19 are threadedly engaged with the threaded rod 9. The movable blocks 10 slide in the guide groove 7 and contact the groove wall of the guide groove 7. Through the contact between the guide groove 7 and the movable blocks 10, the guide groove 7 can guide the movable blocks 10 and prevent the movable blocks 10 from rotating or tilting.

[0025] Mounting brackets 11 are connected to both the top and bottom of the movable block 10. Hydraulic push rods 12 are mounted on the mounting brackets 11. Hollow plates 13 are slidably mounted on the support frame 3 through connecting grooves 5. Connecting strips 14 are connected to both sides of the lower part of the hollow plate 13. A movable plate 15 is slidably connected inside the hollow plate 13. Telescopic rods 20 are rotatably connected to both sides of the movable plate 15. One end of the telescopic rod 20 is inserted into the connecting hole 2. By inserting the telescopic rod 20 into the connecting hole 2, it is convenient for the staff to position the movable plate 15, so that the hollow plate 13 and the movable plate 15 can cover the hydraulic push rods 12.

[0026] A connecting plate 16 is connected to the hollow plate 13. Insert rods 17 are slidably connected to both sides of the connecting plate 16. One end of the insert rod 17 is connected to a pull plate 18. A spring 21 is sleeved on the insert rod 17. One end of the spring 21 is connected to the connecting plate 16, and the other end of the spring 21 is connected to the pull plate 18. The elasticity of the spring 21 allows the insert rod 17 to be inserted into the insertion hole 22 and prevents the insert rod 17 from coming out of the insertion hole 22, thereby allowing the hollow plate 13 to be fixed on the support frame 3.

[0027] The working principle of this utility model is as follows:

[0028] Workers push the connecting strip 14 into the connecting groove 5 to assemble the hollow plate 13 with the support frame 3. Then, they pull the insert rod 17 by pulling the pull plate 18. At this time, the spring 21 is stretched by the pull plate 18, and the spring 21 pushes the insert rod 17 into the insertion hole 22 through its rebound, fixing the hollow plate 13 to the support frame 3. Then, they pull the movable plate 15 to move it, and insert one end of the telescopic rod 20 into the connecting hole 2. This allows the hollow plate 13 and the movable plate 15 to block the area above the hydraulic push rod 12 and prevent falling objects from falling. By starting the motor 8 to drive the threaded rod 9 to rotate, the moving block 10 can move along the threaded rod 9 in the guide groove 7, thereby moving multiple mounting brackets 11 and adjusting the distance between multiple hydraulic push rods 12.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
