Description

Technical Field

[0001] The utility model belongs to the technical field of pipe jacking construction equipment, and specifically relates to a soil transportation device for pipe jacking construction. Background Art

[0002] Pipe jacking construction is a method of burying pipelines with no excavation or little excavation. It requires the use of the jacking force generated by the jacking equipment in the working well to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the debris away.

[0003] The slag is generally transported from the construction site to the slag placement site by a wheelbarrow. After transporting the slag, the existing wheelbarrow uses the method of flipping the hopper to dump the slag out. This process requires overcoming the weight of the slag itself, which requires a lot of strength from the workers. In addition, the dumping process consumes a lot of strength, and the unloading burden is heavy for the workers.

[0004] Therefore, a soil transportation device for pipe jacking construction is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a soil transportation device for pipe jacking construction to solve the problem that the existing wheelbarrow unloading places a heavy burden on the workers.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a soil transportation device for jacking pipe construction, comprising: a vehicle body, the vehicle body comprising a hopper, a limiting plate, a limiting block, a guide cross bar, a discharge port, a connecting partition and an inclined surface, a movable frame is arranged below the vehicle body, and comprises a positioning column and a protrusion, a connecting top plate is connected to the positioning column by screws, and comprises a force block and an inclined force surface, the positioning frame is sleeved on the outside of the guide cross bar and contacts the force block, and a support spring is arranged between the connecting top plate and the movable frame.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, a discharge port is provided on the lower surface of the hopper, a connecting partition is provided inside the discharge port, the top end of the connecting partition is an arc-shaped surface, and an inclined surface is provided on the bottom wall inside the hopper.

[0009] Furthermore, a limiting plate, a limiting block and a guide cross bar are provided on the outer surface of the hopper, and a hole is provided on the upper surface of the limiting plate.

[0010] Furthermore, the movable frame includes a frame body, and the upper surface of the frame body is provided with a discharge hole, a positioning column and a protrusion.

[0011] Furthermore, the upper surface of the protrusion is an arc-shaped surface, and the protrusion extends to the inside of the discharge port.

[0012] Furthermore, the positioning column passes through the hole, and a threaded hole is provided on the upper surface of the positioning column.

[0013] Furthermore, the connecting top plate includes a plate body, a connecting hole is provided on the upper surface of the plate body, a force-bearing block is provided at the bottom end of the plate body, and an inclined force-bearing surface is provided on a side of the force-bearing block away from the vehicle body.

[0014] Furthermore, the positioning frame includes a transverse plate, a bracket is provided on the top end of the transverse plate, and the bracket is sleeved on the outside of the guide cross bar.

[0015] Furthermore, a contact frame is provided at the bottom end of the transverse plate, and the contact frame contacts the lower surface of the force-bearing block.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model provides a soil transportation device for pipe jacking construction. By setting components such as a vehicle body and a movable frame, the discharge port can be blocked by the movable frame through the matching relationship between the vehicle body and the movable frame. At this time, the debris in the hopper cannot be discharged from the discharge port. When the movable frame moves downward, the discharge port is opened, so that the debris in the hopper can be discharged normally.

[0018] 2. The utility model provides a soil transportation device for pipe jacking construction, which realizes the effect of controlling the position of the movable frame by setting the connecting top plate, the supporting spring and the positioning frame. By pulling out the positioning frame, the positioning frame is separated from the connecting top plate. At this time, the movable frame loses support and can move downward under the action of the gravity of the slag to overcome the elastic force of the supporting spring, so that the slag can be discharged from the discharge port. When the discharge is completed, the movable frame is reset under the action of the elastic force of the supporting spring and the position is fixed under the action of the positioning frame.

[0029] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0030] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0031] Example 1

[0032] See also Figure 1-Figure 4 As shown, a soil transportation device for pipe jacking construction comprises:

[0033] The vehicle body 1 comprises a hopper 11, a limiting plate 12, a limiting block 13, a guiding cross bar 14, a discharge port 15, a connecting partition 16 and an inclined surface 17. The lower surface of the hopper 11 is provided with the discharge port 15, the inside of the discharge port 15 is provided with a connecting partition 16, the top of the connecting partition 16 is an arc surface, the bottom wall inside the hopper 11 is provided with an inclined surface 17, the outer surface of the hopper 11 is provided with the limiting plate 12, the limiting block 13 and the guiding cross bar 14, and the upper surface of the limiting plate 12 is provided with holes;

[0034] Based on the above structure, the hopper 11 plays the role of placing debris, and the debris can be discharged from the discharge port 15, and the arc surface and the inclined surface 17 at the top of the connecting partition 16 help the debris to slide downward, making the debris discharge smoother, and the guide cross bar 14 supports and limits the positioning frame 5, so that the positioning frame 5 can only move along the direction of the guide cross bar 14, and the limiting block 13 limits the movement of the connecting top plate 3, so that the connecting top plate 3 can only move to the position of the limiting block 13 at the lowest, and the limiting plate 12 allows the movable frame 2 to move only vertically.

[0035] like Figure 1 and Figure 5 As shown, the movable frame 2 is arranged below the vehicle body 1 and includes a positioning column 23 and a protrusion 24. The movable frame 2 includes a frame body 21. The upper surface of the frame body 21 is provided with a discharge hole 22, a positioning column 23 and a protrusion 24. The upper surface of the protrusion 24 is an arc surface. The protrusion 24 extends to the inside of the discharge port 15. The positioning column 23 passes through the hole. The upper surface of the positioning column 23 is provided with a threaded hole.

[0036] Based on the above structure, the protrusion 24 plays the role of blocking the discharge port 15, so that the movable frame 2 is in Figure 1 When in the middle state, it is ensured that the slag will not leak from the discharge port 15. The positioning column 23 cooperates with the limiting plate 12 so that the movable frame 2 can only move vertically, and the range of movement is limited by the connection top plate 3 and the limiting block 13. The curved surface makes the slag discharge smoother.

[0037] like Figure 1 and Figure 6 As shown, the connecting top plate 3 is connected to the positioning column 23 by screws, and includes a force block 33 and an inclined force surface 34. The connecting top plate 3 includes a plate body 31, and the upper surface of the plate body 31 is provided with a connecting hole 32. The bottom end of the plate body 31 is provided with a force block 33, and the side of the force block 33 away from the vehicle body 1 is provided with an inclined force surface 34;

[0038] A support spring 4, which is arranged between the connecting top plate 3 and the movable frame 2;

[0039] Based on the above structure, the plate body 31 is connected to the positioning column 23 by screws. When the movable frame 2 moves downward, it can drive the connecting top plate 3 to move together. Conversely, when the inclined force surface 34 moves upward under the extrusion of the positioning frame 5, the plate body 31 drives the movable frame 2 to move upward together. The setting of the inclined force surface 34 makes it possible for the positioning frame 5 to squeeze the connecting top plate 3, and the interaction force between the two has a vertical component, thereby causing the connecting top plate 3 to move upward.

[0040] like Figure 1 , Figure 7 and Figure 8 As shown, the positioning frame 5 is sleeved on the outside of the guide cross bar 14 and contacts the force block 33. The positioning frame 5 includes a transverse plate 51. A bracket 53 is provided at the top of the transverse plate 51. The bracket 53 is sleeved on the outside of the guide cross bar 14. A contact frame 52 is provided at the bottom of the transverse plate 51. The contact frame 52 contacts the lower surface of the force block 33.

[0041] Based on the above structure, the bracket 53 cooperates with the guide cross bar 14 so that the positioning frame 5 can only move along the direction of the guide cross bar 14. In addition to being pressed against the inclined force-bearing surface 34, the bracket 53 also contacts the lower surface of the force-bearing block 33. When in contact, the discharge port 15 is in a blocked state, that is, Figure 1 status in .

[0042] Example 2

[0043] On the basis of the first embodiment, by arranging power supplies, control switches, electric push rods (or pneumatic push rods) and other components on both sides of the vehicle body 1, the displacement of the positioning frame 5 is controlled by means of electric push rods, thereby realizing the vertical movement of the movable frame 2. Compared with manual control, this method is more convenient and stable.

[0044] In actual use of the above embodiment, the slag is dumped into the hopper 11. When the cart is transported to the unloading location, the slag can be unloaded from the discharge port 15 under the action of gravity by pulling out the positioning frame 5. In the unloading process, when part of the slag is unloaded, since the distance between the ground and the hopper 11 is not enough to unload all the slag, two methods can be used for unloading. One is to move the cart after unloading part of the slag and continue unloading at another location. The other is to manually disperse the unloaded slag to the surrounding area after unloading part of the slag to leave enough space for unloading.

[0045] After the slag is unloaded, the movable frame 2 is reset under the action of the upward elastic force of the support spring 4 (the support spring 4 can only play the role of driving the movable frame 2 to reset). After the movable frame 2 is reset, it moves the positioning frame 5 so that the positioning frame 5 contacts the bottom surface of the force block 33. At this time, under the action of friction, the positioning frame 5 and the force block 33 remain relatively fixed;

[0046] The slag transportation device reduces the work intensity and workload of construction personnel by sacrificing the unloading speed to obtain more convenient unloading, and the soil transportation device is more suitable for slag with relatively loose and dry soil.

[0047] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
