Description

Technical Field

[0001] The invention relates to the technical field of municipal road construction machinery, and in particular to compaction equipment for municipal road construction. Background Art

[0002] During the construction of municipal roads, the roadbed needs to be leveled and compacted. When compacting a large roadbed, it can be done by a large roller. However, when constructing municipal roads, it often involves small-scale compaction work such as local repairs to the road surface or backfilling and compaction after foundation pit excavation. At this time, large rollers are not suitable due to cost and size reasons. Therefore, some small compaction machinery is needed to complete the work.

[0003] A Chinese patent with patent application number: CN202110916384.1 discloses a road construction foundation pavement compaction device. The patent drives the crankshaft to rotate by rotating the motor, so that the percussion head compacts the roadbed.

[0004] The above patent has at least the following problems when used:

[0005] First, the rotation of the crankshaft drives the striking head to rise and fall. When the striking head descends, it compacts the roadbed. The striking head does not accumulate momentum and has no rapid impact and descends, resulting in insufficient impact force of the striking head and poor compaction effect.

[0006] Second, dust will be generated during the compaction process of the roadbed, and the above patent cannot sprinkle water while the roadbed is compacted to reduce the dust;

[0007] Third, when a road is being built, there are two situations for compacting the roadbed. One is large-scale continuous compaction, which is suitable for compaction after the roadbed surface is leveled; the other is small-scale reciprocating compaction, which is suitable for compaction after foundation pit excavation and backfilling. The above patent cannot adapt to the roadbed compaction work in both situations. Summary of the invention

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figure 1-17 As shown, the present invention has the following embodiments.

[0053] Example 1

[0054] A compacting device for municipal road construction, comprising a front-to-rear symmetrical support plate 11, a first support plate 12 is fixedly connected between the left ends of the support plates 11, a second support plate 13 is fixedly connected between the right ends of the support plates 11, steering wheels 14 are evenly arranged longitudinally below the first support plate 12, an axle 15 is rotatably connected between the right ends of the support plates 11, both ends of the axle 15 are fixedly connected to walking wheels 16, and a control frame 17 is fixedly connected to the left side of the support plate 11; a mounting seat 18 is slidably connected between the support plates 11, a mounting cylinder 19 is rotatably connected in the mounting seat 18, the bottom of the mounting cylinder 19 is open, and a water tank 110 is fixedly connected to the top plate of the mounting cylinder 19;

[0055] A compacting device and a watering device are provided in the installation cylinder 19. The compacting device is used to compact the roadbed, and the watering device is used to spray the water in the water tank 110 on the roadbed to achieve dust reduction function.

[0056] The mounting seat 18 is connected to the rear support plate 11 via a moving device, and the moving device is used to drive the mounting seat 18 to move left and right;

[0057] The mounting seat 18 is connected to the front bracket plate 11 through a rotating device, and the rotating device is used to drive the mounting cylinder 19 to rotate;

[0058] It also includes a power device, which is used to provide power for the rotating device and the moving device, and is also used to drive the axle 15 to rotate.

[0059] The working principle of this embodiment is that the compacting device is used to compact the roadbed. During this process, the sprinkler sprays the water in the water tank 110 on the roadbed to achieve dust reduction. When the power device drives the rotating device, it drives the mounting cylinder 19 to rotate so that the compacted areas overlap with each other to achieve comprehensive compaction work.

[0060] When the power device drives the axle 15 to rotate, the walking wheel 16 rotates, thereby realizing self-propelled movement of the equipment, thereby performing continuous compaction over a large range. Since a steering wheel 14 is provided, the walking direction of the equipment can be controlled by the control frame 17; when the power device drives the moving device, the mounting seat 18, the mounting cylinder 19 and the compaction device can be moved left and right, thereby performing reciprocating compaction over a small range.

[0061] Example 2

[0062] The tamping device includes a tamping motor 21, a U-shaped frame 22 and a tamping seat 23; the bottom plate of the water tank 110 is arched upward to form an installation cavity, the tamping motor 21 is fixedly connected in the installation cavity, the center of the installation cylinder 19 is rotatably connected to the main shaft 24, the tamping motor 21 is provided with a first output shaft pointing vertically downward, the first output shaft is connected to the main shaft 24 through a coupling, the bottom of the main shaft 24 is fixedly connected to a swivel seat 25, the side circumference of the swivel seat 25 is evenly fixedly connected with a plurality of groups of support rods 26, the U-shaped frame 22 is fixedly connected to the head of each group of support rods 26, the two ends of the U-shaped frame 22 are fixedly connected with T-shaped sliders 27, the inner wall of the installation cylinder 19 is provided with a slide groove 28 adapted to the slider 27, the tamping seat 23 is slidably connected to the bottom plate of the U-shaped frame 22, the top plate of the tamping seat 23 is slidably connected with a lifting cylinder 29, the bottom of the lifting cylinder 29 is fixedly connected with a sliding plate 210, and the sliding plate 210 is slidably connected to the tamping seat 23 Inside, buffer springs 211 are evenly fixedly connected around the sliding plate 210 and the bottom plate of the tamping seat 23, force storage springs 212 are fixedly connected between the sliding plate 210 and the top plate of the U-shaped frame 22, lifting rods 213 are symmetrically fixedly connected to the upper part of the lifting cylinder 29, lifting grooves 214 are provided on the vertical plate of the U-shaped frame 22, lifting grooves 215, translation grooves 216 and release grooves 217 are evenly opened around the inner wall of the mounting cylinder 19, the top of the lifting groove 215 is connected to the top of the release groove 217 through the translation groove 216, the bottom of the lifting groove 215 is connected to the bottom of the release groove 217, the head of the lifting rod 213 on one side is located in the lifting groove 214, and the head of the lifting rod 213 on the other side is located in the lifting groove 215, the translation groove 216 and the release groove 217, a first battery 218 is provided on the mounting cylinder 19, and the tamping motor 21 is powered by the first battery 218.

[0063] To increase the impact force of the tamping seat 23 and improve the tamping effect, Figure 3 As shown, the tamping motor 21 is powered by the first battery 218. When the tamping motor 21 is working, it drives the main shaft 24, the rotating seat 25, the support rod 26 and the U-shaped frame 22 to rotate. During this process, the tamping seat 23 and the lifting cylinder 29 rotate synchronously.

[0064] like Fig.10 As shown, the head of the lifting rod 213 on one side is located in the lifting groove 214, and the head of the lifting rod 213 on the other side is located in the lifting groove 215, the translation groove 216 and the release groove 217. The direction of the tamping motor 21 is set so that the tamping seat 23 and the lifting cylinder 29 rotate clockwise when viewed from top to bottom. In the initial state, the lifting rod 213 is located at the bottom of the lifting groove 215. During the clockwise rotation, the lifting rod 213 rises along the lifting groove 215, thereby driving the lifting cylinder 29 and the tamping seat 23 rise, the gravity of the tamping seat 23 rises to accumulate potential, the accumulation spring 212 is compressed, and a second accumulation of potential is performed. When the lifting rod 213 is located in the translation groove 216, the height of the lifting cylinder 29 and the tamping seat 23 remains unchanged. When the lifting rod 213 moves to the bottom of the release groove 217, due to the gravity and the compression reaction force of the spring, the lifting cylinder 29 and the tamping seat 23 drop rapidly and have a large downward impact force. The tamping seat 23 compacts the roadbed, thereby having a better compaction effect.

[0065] Furthermore, when the lifting rod 213 is located in the translation groove 216, the sliding plate 210 contacts the top of the inner cavity of the tamping seat 23. At this time, the buffer spring 211 is in a natural state, and the bottom of the tamping seat 23 is flush with the lower surface of the bottom plate of the U-shaped frame 22. The inner wall of the mounting tube 19 is fixedly connected with a picking knife 219 at the position corresponding to the translation groove 216, and the upper surface of the picking knife 219 is flush with the lower surface of the bottom plate of the U-shaped frame 22.

[0066] Since water is sprinkled during the compaction process to reduce dust, during the compaction of the roadbed, mud may adhere to the bottom of the compaction seat 23. The mud forms a buffer layer, which makes the compaction effect worse. In order to remove the mud, a pick knife 219 is provided in this embodiment. When the lifting rod 213 is located in the translation groove 216, the bottom of the compaction seat 23 is flush with the lower surface of the bottom plate of the U-shaped frame 22. During this process, the bottom of the compaction seat 23 will pass through the position of the pick knife 219, and the mud adhered to the bottom of the compaction seat 23 will be removed by the pick knife 219.

[0067] Furthermore, when the bottom of the tamping seat 23 contacts the roadbed, the buffer springs 211 are in a compressed state, and the sum of the compression forces of the buffer springs 211 is less than the sum of the gravity of the sliding plate 210 and the lifting cylinder 29 .

[0068] In order to ensure that the tamping seat 23 is in full contact with the roadbed and the lifting rod 213 can accurately move to the bottom of the release groove 217 and the lifting groove 215, when the tamping seat 23 is in contact with the roadbed, the lifting cylinder 29 and the sliding plate 210 descend, so that the lifting shaft moves to the bottom of the release groove 217 and the lifting groove 215, so as to facilitate subsequent lifting.

[0069] Furthermore, the sprinkler device includes a delivery bin 31 and a piston 32; the delivery bin 31 is fixedly connected to the lower surface of the top plate of the mounting tube 19 and is symmetrically arranged front to back, a push rod 33 is slidably connected in the side plate of the delivery bin 31 close to the main shaft 24, a push block 34 is fixedly connected to one end of the push rod 33 close to the main shaft 24, a cam 35 is fixedly connected to the main shaft 24, the push block 34 abuts against the cam 35, an air hole 36 is opened in the bottom plate of the delivery bin 31 close to the main shaft 24, the piston 32 is sealingly slidably connected in the delivery bin 31, the piston 32 is fixedly connected to the push rod 33, and a reset spring 37 is sleeved on the push rod 33 in the delivery bin 31 to reset The two ends of the spring 37 are respectively fixedly connected to the piston 32 and the side plate of the delivery bin 31. A pumping chamber is formed between the piston 32 and the side plate of the delivery bin 31 away from the main shaft 24. The pumping chamber is connected to the water tank 110 through a suction pipe 38. A sprinkler pipe 39 is also fixedly connected to the pumping chamber. An atomizing nozzle 310 is fixedly connected to the bottom of the sprinkler pipe 39. A first one-way valve 311 and a second one-way valve 312 are respectively provided in the suction pipe 38 and the sprinkler pipe 39. The first one-way valve 311 allows the fluid to pass in the direction pointing to the pumping chamber, and the second one-way valve 312 allows the fluid to pass in the direction away from the pumping chamber.

[0070] In order to reduce the generation of dust, this embodiment discloses a sprinkler device, such as Figure 3 and 4 As shown, when the equipment is working, the cam 35 rotates with the main shaft 24. The cam 35 is elliptical. When the contact position between the cam 35 and the push block 34 transitions from the short axis end to the long axis end, the push block 34, the push rod 33 and the piston 32 are pushed away from the main shaft 24, and the return spring 37 is extended. On the contrary, when the contact position between the cam 35 and the push block 34 transitions from the long axis end to the short axis end, the return spring 37 is restored, and the piston 32 moves in the opposite direction, so that the piston 32 reciprocates, and the water in the water tank 110 is extracted through the water pumping pipe 38 and the first one-way valve 311, and enters the atomizing nozzle 310 through the sprinkler pipe 39 and the second one-way valve 312 for spraying.

[0071] The working principle of this embodiment is that the compacting motor 21 drives the compacting seat 23 and the lifting cylinder 29 to rotate. When the lifting rod 213 is in the lifting groove 215, the compacting seat 23 and the lifting cylinder 29 rise to accumulate momentum. When the lifting rod 213 is in the translation groove 216, the soil at the bottom of the compacting seat 23 is removed by the pick 219. When the lifting rod 213 moves to the top of the release groove 217, the compacting seat 23 quickly impacts and descends to compact the roadbed. The compacting motor 21 also drives the cam 35 to rotate, so that the piston 32 moves back and forth, and the water in the water tank 110 is sprayed out through the atomizing nozzle 310, thereby reducing the dust generated during the compaction process.

The power device is used to drive the reciprocating screw rod 41 to rotate.
