Description

Technical Field

[0001] The invention relates to the technical field of brick paving machines, in particular to a sidewalk brick paving machine capable of avoiding roadside trees. Background Art

[0002] A special pavement brick paving machine for sidewalks is a brick paving machine for paving and constructing sidewalks. It is widely used in sidewalk construction and has a good use effect. With the gradual increase in the demand for road construction, the utilization of sidewalk space in urban roads has become more obvious. The underground is the "base camp" of various pipelines, occupied by street lights, power supply, communications and other pipelines. The ground is the "base" of various ancillary facilities, occupied by greening, advertising, newsstands and other facilities. Among them, street trees refer to tree species planted on both sides of the road and located on the sidewalk, which provide shade for vehicles and pedestrians and constitute street scenes.

[0003] In order to properly handle the relationship between tree planting and the environment, and to ensure that trees have a reasonable living space after being planted, street trees need to be planted in tree pits with equal spacing. During the construction of the sidewalk, tree pits will first be built at equal intervals on the sidewalk, and then bricks will be laid on the sidewalk. Finally, the staff will plant trees and other green plants inside the tree pits.

[0004] In the prior art, brick laying equipment can only lay bricks on sidewalks when there are no other objects blocking the surface. If bricks are laid on a sidewalk with equally spaced tree pits, due to the influence of the brick laying equipment itself, it is impossible to adaptively avoid the tree pits of street trees, resulting in a significant reduction in brick laying efficiency. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a sidewalk brick paving machine that can avoid roadside trees, so as to solve the technical problem that the brick paving equipment in the prior art can only lay bricks on the sidewalk when there are no other objects blocking the surface. If bricks are laid on a sidewalk with equally spaced tree pits, due to the influence of the brick paving equipment itself, it is impossible to adaptively avoid the tree pits of the roadside trees, resulting in a greatly reduced brick paving efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sidewalk brick paving machine capable of avoiding street trees, comprising a paving machine, a fixing frame is fixed at one end of the paving machine, a plurality of groups of single paving components are rotatably connected at one end of the fixing frame, a plurality of groups of bricks are evenly arranged on the top of the plurality of paving boards, and a plurality of groups of tree pits matching the street trees are arranged at intervals on the ground;

[0007] The single laying assembly includes a laying plate, a rotating frame, a first gear, a first roller, a toothed plate, a second gear, a connecting shaft, a lifting gear, a lifting limit plate and a first torsion spring. The multiple laying plates and the fixed frame are rotationally connected via a group of flip shafts, the rotating frame and the laying plates are rotationally connected via a rotating shaft, and two groups of first rollers rotate on both sides of the bottom of the rotating frame, the first gear is fixed to the outside of the rotating shaft, and the first gear is located inside the laying plate, the toothed plate is located inside the laying plate and meshed with the first gear, the second gear is located inside the end of the laying plate and meshed with the toothed plate, the second gear and the two groups of lifting gears are coaxial via the connecting shaft, and one end of the lifting gear is meshed with a lifting limit plate;

[0008] A first torsion spring is arranged on the outside of the rotating shaft of the rotating frame, and the first torsion spring is located on both sides of the inside of the paving plate, and the two sides of the two groups of the first torsion spring are respectively fixedly connected to the rotating shafts of the paving plate and the rotating frame, and the single paving assembly also includes a bottom roller, a conveying gear, and a conveying roller. The conveying gear and the conveying roller are rotatably connected at the middle position and both sides of the inside of the paving plate, and the end of each group of the paving plates is rotatably connected to the bottom roller, and a plurality of groups of teeth are evenly fixedly arranged on the outside of the bottom roller, wherein the bottom roller with teeth can better disperse and level the ground soil, and a paving pad is fixed at the end of each group of the paving plates.

[0009] By adopting the above technical solution, the paving machine is composed of multiple groups of single paving components in parallel. When the paving machine is laying bricks on the sidewalk, when the first roller of one or more groups of single paving components contacts the tree pit, as the paving machine continues to move, the first roller drives the rotating frame to flip to a certain extent under the obstruction of the tree pit. At this time, the flipped rotating frame drives the first gear to rotate, the first gear drives the toothed plate to move, and the toothed plate drives the second gear to rotate. Since the second gear and the two groups of lifting gears are coaxial, the two groups of lifting gears drive the lifting limit plate. The paving plate is extended, and then the limit plate is raised and lowered to block and limit the brick at the end. As the paving machine continues to move, the first roller is blocked by the paving plate and has rotated to the maximum limit. At this time, the first roller moves to the top of the tree pit. Then, the paving plate, under the action of the first roller and the tree pit, causes one or more groups of single paving components to rotate upward along the flip axis, thereby causing one or more groups of single paving components to avoid the tree pit, thereby making the present invention as a whole more suitable for paving operations on sidewalks with tree pits for street trees, and effectively improving the paving efficiency.

[0010] The present invention is further configured such that a transmission rod is rotatably connected inside the fixed frame, a plurality of groups of power gears corresponding to the plurality of monomer laying components are evenly and fixedly arranged on the outside of the transmission rod, and each group of power gears is meshed with each group of conveying gears, a double-axis motor is installed at the bottom end of the laying machine, the output shafts on both sides of the double-axis motor and the transmission rod are connected by a synchronous belt transmission, and a fixing plate matching the double-axis motor is fixed inside the laying machine.

[0011] By adopting the above technical solution, the dual-axis motor drives multiple sets of power gears to rotate through the transmission rod, and then the power gears engage with multiple sets of conveying gears to rotate, so that the conveying rollers rotate to convey the bricks.

[0012] The present invention is further configured such that a plurality of groups of fixed blocks are evenly fixedly arranged at the top of the interior of the paving machine, both sides of each group of the fixed blocks are rotatably connected with connecting rods, the ends of each two groups of the connecting rods are movably connected with extrusion rollers, each two groups of the connecting rods and each group of fixed blocks are movably connected via a second torsion spring, and a rubber ring is fixedly arranged on the outer surface of the extrusion roller.

[0013] By adopting the above technical solution, the extrusion roller and the laying machine are movably connected through a fixed block, a connecting rod and a second torsion spring, and the bottom of the extrusion roller squeezes the bricks to a certain extent, thereby increasing the friction between the conveying roller and the bricks, so that the bricks will not slip during transportation.

[0014] The present invention is further configured such that powered walking wheel assemblies are provided at the four corners of the bottom of the paving machine, a control box matched with the four sets of powered walking wheel assemblies is provided at the bottom of the paving machine, and the control box and the dual-axis motor are electrically connected.

[0015] By adopting the above technical solution, the control box plays a role in the power supply and centralized control of the entire laying machine, and cooperates with the operation of the staff to enable the laying machine to stably lay bricks on the sidewalk.

[0016] In summary, the present invention mainly has the following beneficial effects:

[0017] 1. The paving machine of the present invention is composed of multiple groups of single paving components arranged in parallel. When the paving machine is paving bricks on the sidewalk, when the first roller of one or more groups of single paving components contacts the tree pit, as the paving machine continues to move, the first roller drives the rotating frame to flip to a certain extent under the obstruction of the tree pit. At this time, the flipped rotating frame drives the first gear to rotate, the first gear drives the toothed plate to move, and the toothed plate drives the second gear to rotate. Since the second gear and the two groups of lifting gears are coaxial, the two groups of lifting gears drive the lifting limit plate to extend out of the paving. The plate is set, and then the lifting limit plate is used to block and limit the bricks at the end. As the paving machine continues to move, the first roller is blocked by the paving plate and has rotated to the maximum limit. At this time, the first roller moves to the top of the tree pit. Then, under the action of the first roller and the tree pit, the paving plate causes one or more groups of monomer paving components to rotate upward along the flip axis, thereby causing one or more groups of monomer paving components to avoid the tree pit, so that the present invention as a whole is more suitable for the paving operation of the sidewalk with the tree pit of the street tree, and the paving efficiency is effectively improved.

[0018] 2. In the present invention, multiple groups of monomer paving components are internally rotatably connected with conveying gears, wherein the conveying gears are meshed with power gears, so that the conveying gears can coaxially drive the conveying rollers to convey bricks. When one or more groups of monomer paving components avoid the tree pits of street trees, one or more groups of monomer paving components flip upward along the flip axis, and at this time the conveying gears are disengaged from the meshing with the power gears, so that the bricks on the one or more groups of monomer paving components that avoid the tree pits of street trees are no longer conveyed, and the remaining monomer paving components that do not need to avoid the tree pits continue to convey bricks. The overall use is relatively convenient and has good adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A sidewalk brick paving machine capable of avoiding roadside trees, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it comprises a laying machine 1, a fixing frame 2 is fixed at one end inside the laying machine 1, and multiple groups of single laying components 3 are rotatably connected at one end of the fixing frame 2, multiple groups of bricks 4 are evenly arranged on the top of multiple groups of laying boards 301, and multiple groups of tree pits 5 matching with roadside trees are arranged at intervals on the ground;

[0031] The single laying assembly 3 includes a laying plate 301, a rotating frame 302, a first gear 303, a first roller 304, a tooth plate 305, a second gear 306, a connecting shaft 307, a lifting gear 308, a lifting limit plate 309 and a first torsion spring 311. The multiple laying plates 301 and the fixed frame 2 are connected to each other through a set of flip shafts 10, and the rotating frame 302 and the laying plates 301 are connected to each other through a rotating shaft, and the two sets of first rollers 304 rotate in On both sides of the bottom of the rotating frame 302, the first gear 303 is fixed on the outside of the rotating shaft, and the first gear 303 is located inside the laying plate 301, the tooth plate 305 is located inside the laying plate 301 and meshed with the first gear 303, the second gear 306 is located inside the end of the laying plate 301 and meshed with the tooth plate 305, the second gear 306 and the two sets of lifting gears 308 are coaxial through the connecting shaft 307, and one end of the lifting gear 308 is meshed with a lifting limit plate 309;

[0032] A first torsion spring 311 is arranged on the outside of the rotating shaft of the rotating frame 302, and the first torsion spring 311 is located on both sides of the inside of the laying plate 301, and the two sides of the two groups of first torsion springs 311 are fixedly connected to the rotating shafts of the laying plate 301 and the rotating frame 302 respectively. The single laying component 3 also includes a bottom roller 310, a conveying gear 312, and a conveying roller 313. The conveying gear 312 and the conveying roller 313 are rotatably connected at the middle position and both sides of the laying plate 301 respectively, and the end of each group of laying plates 301 is rotatably connected to the bottom roller 310, and a plurality of groups of teeth are evenly fixedly arranged on the outside of the bottom roller 310, wherein the bottom roller 310 with teeth can better disperse and level the ground soil, and a laying pad 12 is fixed at the end of each group of laying plates 301. Assume that the machine 1 is composed of multiple groups of single laying components 3 arranged in parallel. When the laying machine 1 is laying bricks on the sidewalk, when the first roller 304 of one or more groups of single laying components 3 contacts the tree pit 5, as the laying machine 1 continues to move, the first roller 304 drives the rotating frame 302 to flip to a certain extent under the obstruction of the tree pit 5. At this time, the flipped rotating frame 302 drives the first gear 303 to rotate, the first gear 303 drives the tooth plate 305 to move, and the tooth plate 305 drives the second gear 306 to rotate. Since the second gear 306 and the two groups of lifting gears 308 are coaxial, the two groups of lifting gears 308 drive the lifting limit plate 309 to extend out of the laying plate 301, and the lifting limit plate 309 blocks and limits the brick 4 at the end;

[0033] As the paving machine 1 continues to move, since the first roller 304 is blocked by the paving plate 301 and has rotated to the maximum, at this time, the first roller 304 moves to the top of the tree pit 5, and then, under the action of the first roller 304 and the tree pit 5, the paving plate 301 causes one or more groups of single paving components 3 to rotate upward along the flip axis 10, thereby causing one or more groups of single paving components 3 to avoid the tree pit 5, so that the present invention as a whole is more suitable for the paving operation of the sidewalk with the tree pit 5 of the street tree, and effectively improves the paving efficiency.

[0034] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 A transmission rod 6 is rotatably connected inside the fixed frame 2, and multiple groups of power gears 7 corresponding to the multiple groups of monomer laying components 3 are evenly fixed on the outside of the transmission rod 6, and each group of power gears 7 is meshed with each group of conveying gears 312. A double-axis motor 9 is installed at the bottom end of the paving machine 1. The output shafts on both sides of the double-axis motor 9 and the transmission rod 6 are connected by a synchronous belt 8, and a fixed plate 11 matched with the double-axis motor 9 is fixed inside the paving machine 1. By setting the above structure, the double-axis motor 9 drives the multiple groups of power gears 7 to rotate through the transmission rod 6, and then the power gears 7 mesh with the multiple groups of conveying gears 312 to rotate, so that the conveying roller 313 rotates to convey the bricks 4.

[0035] See also Figure 2 and Figure 8 A plurality of fixed blocks 13 are evenly fixed on the top of the paving machine 1, and connecting rods 14 are rotatably connected on both sides of each fixed block 13. Extrusion rollers 15 are movably connected at the ends of every two connecting rods 14. Every two connecting rods 14 and each fixed block 13 are movably connected via a second torsion spring 16, and a rubber ring is fixedly provided on the outer surface of the extrusion roller 15. The present invention sets the above structure, wherein the extrusion roller 15 and the paving machine 1 are movably connected via the fixed block 13, the connecting rod 14 and the second torsion spring 16, and the bottom of the extrusion roller 15 squeezes the brick 4 to a certain extent, thereby increasing the friction between the conveying roller 313 and the brick 4, so that the brick 4 will not slip during the conveying process.

[0036] See also Figure 1 , Figure 2 and Figure 3 Powered walking wheel assemblies 17 are provided at the four corners of the bottom of the paving machine 1. A control box 18 matched with the four sets of powered walking wheel assemblies 17 is provided at the bottom of the paving machine 1, and the control box 18 and the dual-axis motor 9 are electrically connected. The present invention sets the above structure, wherein the control box 18 plays the role of supplying power and centralized control to the entire paving machine 1, and cooperates with the operation of the staff to enable the paving machine 1 to stably lay bricks on the sidewalk.

[0037] The working principle of the present invention is as follows: when in use, the power is turned on, and the laying machine 1 is placed on the sidewalk, wherein the four sets of power walking wheel assemblies 17 can drive the laying machine 1 to walk under the action of the control box 18, and the two sets of power walking wheel assemblies 17 on one side are placed outside the tree pit 5 of the sidewalk;

[0038] First, the staff manually stacks the bricks 4 evenly from the top of the laying machine 1. As the control box 18 transmits power to the double-axis motor 9, the double-axis motor 9 drives the transmission rod 6 to rotate through two sets of synchronous belts 8. Multiple sets of power gears 7 corresponding to multiple sets of single laying components 3 are evenly arranged on the outside of the transmission rod 6.

[0039] The paving machine 1 is composed of a plurality of groups of single paving components 3 arranged in parallel. When the paving machine 1 is paving bricks on the sidewalk, when the first roller 304 of one or more groups of single paving components 3 contacts the tree pit 5, as the paving machine 1 continues to move, the first roller 304 drives the rotating frame 302 to flip to a certain extent under the obstruction of the tree pit 5. At this time, the flipped rotating frame 302 drives the first gear 303 to rotate, the first gear 303 drives the tooth plate 305 to move, and the tooth plate 305 drives the second gear 306 to rotate. Since the second gear 306 and the two groups of lifting gears 308 are coaxial, the two groups of lifting gears 308 drive the lifting limit plate 309 to extend out of the paving plate 301, and the lifting limit plate 309 blocks and limits the brick 4 at the end;

[0040] As the paving machine 1 continues to move, the first roller 304 is blocked by the paving plate 301 and has rotated to the maximum extent. At this time, the first roller 304 moves to the top of the tree pit 5. Then, under the action of the first roller 304 and the tree pit 5, the paving plate 301 causes one or more groups of monomer paving components 3 to rotate upward along the flip axis 10, thereby causing one or more groups of monomer paving components 3 to avoid the tree pit 5, so that the present invention as a whole is more suitable for the paving operation of the sidewalk with the street tree pit 5, and the paving efficiency is effectively improved.

[0041] The plurality of groups of monomer laying components 3 are internally connected with a conveying gear 312, wherein the conveying gear 312 is meshed with the power gear 7, so that the conveying gear 312 can coaxially drive the conveying roller 313 to convey the bricks 4. When one or more groups of monomer laying components 3 avoid the tree pit 5 of the street tree, one or more groups of monomer laying components 3 are turned upward along the turning axis 10, and the conveying gear 312 is disengaged from the meshing with the power gear 7 at this time, so that the bricks 4 on the one or more groups of monomer laying components 3 avoiding the tree pit 5 of the street tree are no longer conveyed, and the remaining monomer laying components 3 that do not need to avoid the tree pit 5 continue to convey the bricks 4. The overall use is relatively convenient and has good adaptability.

[0042] When the first roller 304 of one or more groups of the single laying components 3 is separated from the tree pit 5, the first roller 304 is reset under the action of the first torsion spring 311, so that the first roller 304 and the rotating frame 302 are reset to a vertical state, so that the first roller 304 supports the single laying component 3, and at the same time, the reset of the rotating frame 302 drives the first gear 303 to reverse, and according to the above, the two groups of lifting gears 308 are reversed, so that the two groups of lifting limit plates 309 are retracted into the laying plate 301, and are separated from the limit of the brick 4;

[0043] At the same time, one or more groups of single laying components 3 are reset along the flip axis 10 under the action of their own weight and the weight of the multiple groups of bricks 4 on top thereof, so that the conveying gear 312 is meshed with its corresponding power gear 7 again, so that the bricks 4 can be conveyed again;

[0044] Furthermore, when one or more groups of single laying components 3 avoid the tree pit 5, there is a certain distance between the lifting limit plate 309 and the first roller 304, and thus there is a distance at the front end of the tree pit 5 where no bricks 4 are laid. When one or more groups of single laying components 3 leave the tree pit 5, the first roller 304 is reset, and at this time, the lifting limit plate 309 is freed from the limit on the bricks 4 in advance, and thus there is a distance at the top end of the rear end of the tree pit 5. Then, the staff transfers the excess bricks 4 at the rear end of the top of the tree pit 5 to the position at the front end of the tree pit, and then cuts and reorganizes the bricks 4, and then lays the gap around the tree pit 5 flat. The overall workload of the staff is small, and the later processing is more convenient.

[0045] Furthermore, a plurality of groups of squeezing rollers 15 corresponding to the single paving components 3 are evenly arranged on the top of the paving machine 1, wherein the squeezing rollers 15 and the paving machine 1 are movably connected via a fixed block 13, a connecting rod 14 and a second torsion spring 16, and the bottom of the squeezing rollers 15 squeezes the bricks 4 to a certain extent, thereby increasing the friction between the conveying rollers 313 and the bricks 4, so that the bricks 4 will not slip during the conveying process.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
