Description

Technical Field

[0001] This invention relates to the field of pipeline construction, and in particular to a drainage pipeline construction device. Background Technology

[0002] With the rapid development of urban construction, the government has continuously increased its investment in municipal infrastructure construction. Municipal construction and environmental management have received increasing attention. Drainage pipe networks are an important part of urban municipal construction. In order to reduce the occupation of space, municipal drainage pipes are usually buried underground.

[0003] When installing drainage pipes, a layer of sand cushion is usually laid. The main functions of the sand cushion layer are: first, to increase the load on the foundation and reduce the amount of subsidence; second, to consolidate quickly and improve the stability of the foundation; and third, to distribute the stress evenly and protect the pipes from damage. The sand cushion layer should be made of medium-coarse sand, free of other impurities, and the mud content should be controlled within 5%, otherwise it will be difficult to compact and the strength will be low.

[0004] In actual construction, the sand cushion layer is laid manually. Trucks dump sand into the pipe trench, and then people use shovels and other tools to spread the sand. Because the drainage pipeline is long, a lot of manpower is required during construction, and the spreading efficiency is low. At the same time, the flatness of the manually spread sand is poor, which is not convenient for the later installation of the pipeline. Summary of the Invention

[0034] Example 1

[0035] See Figures 1 to 7 The present invention provides a drainage pipe construction device, including a frame 1 for moving in a pipe trench. A traveling wheel 1-1 is rotatably arranged on both the front and rear sides of the frame 1. A drive motor is further arranged on the frame 1. The motor shaft of the drive motor is coaxially fixed with one of the traveling wheels 1-1. The forward movement of the frame 1 is controlled by the drive motor, which saves labor and improves the stability of the device during use.

[0036] Furthermore, a tow hook is set at each end of the frame 1. When this device is used, it can be connected to the existing construction equipment at the construction site and moved by the construction equipment. A silo 1-2 for storing sand is fixed on the frame 1, and a sand spreading mechanism 2 is set in the middle of the frame 1.

[0037] The sand spreading mechanism 2 includes a mounting frame 2-1 fixedly mounted on the frame 1. The mounting frame 2-1 is L-shaped. The horizontal part of the mounting frame 2-1 is fixedly connected to the frame 1. A leveling unit 2-2 for leveling sand is provided on the vertical part of the mounting frame 2-1, and a driving unit 2-3 for driving the leveling unit 2-2 to move. A compaction mechanism 3 for compacting sand is also provided on the horizontal part of the mounting frame 2-1.

[0038] Two traveling wheels 1-1 near the mounting bracket 2-1 are fixedly connected by a rotating shaft 1-3. A transmission box 1-4 is installed on the rotating shaft 1-3. The input end of the transmission box 1-4 is fixedly connected to the rotating shaft 1-3, and the output end of the transmission box 1-4 is connected to the drive unit 2-3.

[0039] Two sliding rods 2-11 are arranged in parallel on the vertical part of the mounting bracket 2-1. A slider 2-12 is slidably mounted on each sliding rod 2-11. A fixing seat 2-13 is fixedly mounted on the two sliders 2-12. A flattening unit 2-2 is mounted on the fixing seat 2-13.

[0040] The leveling unit 2-2 includes two driven gears 2-21 rotatably mounted at both ends of the lower end of the fixed base 2-13. Each driven gear 2-21 is coaxially fixed with a pusher 2-22, which is an auger. During the rotation of the auger, it can level the sand in the pipe trench. Excess sand can be moved to the sides and forward by the push of the auger. The middle of the fixed base 2-13 is rotatably mounted with a driving gear 2-23, which meshes with the two driven gears 2-21 respectively.

[0041] A transmission sprocket 2-24 is coaxially fixed on the drive gear 2-23, and the transmission sprocket 2-24 extends to the side near the mounting bracket 2-1.

[0042] The drive unit 2-3 includes two drive sprockets 2-31 rotatably mounted on the vertical part of the mounting frame 2-1. The two drive sprockets 2-31 are located at the two ends of the mounting frame 2-1 respectively, and the two drive sprockets 2-31 are connected by a chain 2-32. One of the drive sprockets 2-31 is fixedly connected to the output end of the transmission box 1-4.

[0043] The drive sprocket 2-24 meshes with the chain 2-32. When the chain 2-32 is working, it drives the drive sprocket 2-24 to rotate. The drive sprocket 2-24 drives the two driven gears 2-21 to rotate through the drive gear 2-23, thereby enabling the two pushers 2-22 to work and level the sand and gravel in the pipeline trench.

[0044] A protrusion 2-33 is fixedly provided on one of the links of chain 2-32;

[0045] Two connecting hooks 2-4 are rotatably mounted on the fixed base 2-13. The two connecting hooks 2-4 are located on the upper and lower sides of the chain 2-32 respectively. The connecting hooks 2-4 are L-shaped. A limiting platform is fixedly mounted on one end of the horizontal part of the connecting hooks 2-4. The limiting platforms of the two connecting hooks 2-4 face the chain 2-32 respectively.

[0046] A torsion spring is provided between the connecting hook 2-4 and the fixed seat 2-13. The torsion spring can ensure that the state of the connecting hook 2-4 remains stable. When the protrusion 2-33 rotates to the connecting hook 2-4, the limiting platform overlaps with the protrusion 2-33, and the chain 2-32 can drive the fixed seat 2-13 to move through the connecting hook 2-4.

[0047] Two limiting pins 2-5 are fixedly installed on the vertical part of the mounting bracket 2-1. The two limiting pins 2-5 are located at the two ends of the mounting bracket 2-1 respectively. Each limiting pin 2-5 includes a mounting plate fixedly installed on the mounting bracket 2-1. A top rod is fixedly installed on the mounting plate, and the two top rods are respectively facing the fixed seat 2-13.

[0048] When the vertical part of a connecting hook 2-4 that engages with protrusion 2-33 comes into contact with limit pin 2-5, chain 2-32 drives connecting hook 2-4 to continue moving. Connecting hook 2-4 rotates under the action of limit pin 2-5. At this time, the limit platform of connecting hook 2-4 separates from protrusion 2-33. Chain 2-32 continues to rotate, but the rotating chain 2-32 does not drive fixed seat 2-13 to move. When protrusion 2-33 of chain 2-32 moves to engage with another connecting hook 2-4, the rotating chain 2-32 drives fixed seat 2-13 to move in the opposite direction until it contacts another limit pin 2-5. Through the two rotating connecting hooks 2-4, the unidirectional rotating chain 2-32 can drive fixed seat 2-13 to reciprocate along sliding rod 2-11, which can expand the working width of paving unit 2-2 and make the sand in the pipe trench more even.

[0049] Furthermore, each mounting plate and mounting frame 2-1 are detachably connected. By adjusting the position of the two limiting pins 2-5 on the mounting frame 2-1, the width of the leveling unit 2-2 can be adjusted. The device can be rotated to a suitable working position according to the width of the sand being laid, thus expanding the application range of the device.

[0050] The compaction mechanism 3 includes a compaction plate 3-1 that is slidably connected to the horizontal part of the mounting frame 2-1. Several columns 3-2 are fixedly installed on the plate body of the compaction plate 3-1. Each column 3-2 is slidably connected to the horizontal part of the mounting frame 2-1. A connector 3-3 is rotatably installed at the upper end of the column 3-2. The connector 3-3 is connected to the rotating shaft 1-3.

[0051] The connector 3-3 includes an eccentric sleeve 3-4 fixedly connected to the rotating shaft 1-3, a bushing 3-5 sleeved on the outside of the eccentric sleeve 3-4, a connecting rod 3-6 fixedly installed on one side of the bushing 3-5, and the connecting rod 3-6 rotatably connected to the column 3-2.

[0052] The rotation axis 1-3 of the eccentric sleeve 3-4 is not coaxial with the physical axis.

[0053] When the rotating shaft 1-3 rotates, it drives the eccentric sleeve 3-4 to rotate. Since the rotation axis 1-3 of the eccentric sleeve 3-4 is not on the same axis as the physical axis, under the action of the connecting rod 3-6, it can drive the compaction plate 3-1 to move up and down, so that the laid sand and gravel can be compacted.

[0054] The transmission box 1-4 includes a box body 1-41 fixedly mounted on the mounting bracket 2-1. An input gear 1-42 is rotatably mounted inside the box body 1-41. One side of the input gear 1-42 meshes with an intermediate gear 1-43. The intermediate gear 1-43 is rotatably connected to the box body 1-41. One side of the intermediate gear 1-43 is coaxially fixed with an intermediate bevel gear 1-44. An output bevel gear 1-45 meshes with the intermediate bevel gear 1-44. A transmission shaft is fixedly mounted on one side of the output bevel gear 1-45. The transmission shaft is coaxially fixedly connected to one of the drive sprockets 2-31.

[0055] The number of teeth on the input gear 1-42 is greater than the number of teeth on the intermediate gear 1-43, and the number of teeth on the intermediate bevel gear 1-44 is greater than the number of teeth on the output bevel gear 1-45. The large gear drives the small gear for speed-increasing transmission. Through the transmission box 1-4, the output speed of the rotating shaft 1-3 is increased, thereby increasing the transmission speed of the chain 2-32 and improving the working speed of the sand-spreading mechanism 2.

[0056] Several discharge ports are provided at the bottom of the hopper 1-2, and a baffle is slidably installed at each discharge port.

[0057] When using this device, first place the sand or tailings that need to be laid in the pipe trench into the hopper 1-2. When filling the hopper 1-2 with materials, move the baffle to block the discharge port at the bottom of the hopper 1-2 to prevent materials from leaking onto the ground. When the vehicle frame 1 moves, open the baffle and the materials in the hopper 1-2 will spill into the pipe trench as the vehicle frame 1 moves.

[0058] The opening and closing degree of the baffle can be adjusted according to the moving speed of the frame 1 and the thickness of the sand to be laid, making it more adaptable.

[0059] When using this invention, sand or tailings sand to be laid in the pipe trench is placed into the hopper 1-2. The opening and closing degree of the baffle can be adjusted according to the moving speed of the frame 1 and the required thickness of the sand. The frame 1 is pushed by the construction personnel. No separate power source is required, which is more suitable for long-distance outdoor construction. During the movement of the frame 1, the leveling unit 2-2 is driven by the drive unit 2-3 to move back and forth. When the leveling unit 2-2 moves back and forth, the two pushers 2-22 rotate. During the rotation of the pushers 2-22, they can level the sand in the pipe trench. Excess sand can be moved to the sides and forward by the auger. During the movement of the frame 1, the compaction plate 3-1 can be moved up and down to compact the laid sand and gravel.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
