Description

Technical Field

[0001] This invention relates to the field of road engineering equipment technology, and in particular to a honeycomb network roadbed laying device for road construction. Background Technology

[0002] A roadbed is the foundation of a track or road surface, and is an earthwork structure formed through excavation or filling. The main function of a roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track, vehicles, road surface, and traffic loads, while simultaneously transferring and dispersing the loads deep into the foundation. Honeycomb grids are a new type of material structure widely used in recent years in transportation, water conservancy, municipal, landscaping, and soil and water conservation projects. Honeycomb grids can be assembled into cages according to engineering design requirements, filled with materials such as boulders, and connected together to form a unified structure, serving as a new technology for embankment, roadbed protection, and other engineering projects.

[0003] Therefore, the standards for laying honeycomb grids must be high. Currently, the laying of honeycomb grids is mostly done manually by stretching and fixing them. The folded honeycomb grids are stretched into a mesh shape as a whole, and soil is filled in after the entire honeycomb grid is laid. The roadbed laying process is complicated and wastes manpower and resources. It is also impossible to guarantee the degree of stretching of each grid of the honeycomb grid. The grids in different parts of the honeycomb grid are of different sizes, and the roadbed support provided is uneven, which affects the stability of the roadbed laid later. In addition, when the soil is laid, stones of various sizes enter the honeycomb grid together, causing the bottom to not fit tightly, which also affects the stability of the roadbed.

[0004] To address the shortcomings of existing technologies, we have developed a honeycomb network subgrade laying device for road construction that can be stretched row by row. Summary of the Invention

[0005] To overcome the shortcomings of uneven and inefficient overall stretching of honeycomb grids, and the inability to guarantee the stretching state of each grid, a honeycomb grid subgrade laying device for road construction that can stretch row by row is provided.

[0010] Preferably, the bottom surface of the discharge side of the first limiting plate is lower than the bottom surface of the infeed side.

[0011] Preferably, the shaping and limiting mechanism includes a third slider, which is slidably connected to a first groove. The third slider is ball-connected to a first fixing ring, which is rotatably connected to a limiting wheel. The limiting wheel is slidably connected to a splined shaft, and the splined shaft is evenly spaced with limiting wheels. A third fixing rod is fixedly connected to the vehicle body, which is rotatably connected to the splined shaft. A second fixing ring is rotatably connected to the limiting wheel, which is fixedly connected to a second scissor-type telescopic frame.

Detailed Implementation

[0034] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, the terms "upper," "lower," "left," "right," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. All the above orientations are based on the accompanying drawings. Figure 1 As indicated by the direction, the vehicle's direction of movement is "forward". Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Example 1 A honeycomb network subgrade laying device for road construction, such as Figures 1-4 As shown, the device includes a vehicle body 1, a flap 2 rotatably connected to the vehicle body 1, a base plate 3 fixedly connected to the bottom of the vehicle body 1, a pusher plate 4 slidably connected to the base plate 3, a first electric push rod 5 fixedly connected to the vehicle body 1, the pusher plate 4 being fixedly connected to the first electric push rod 5 and slidably connected to the vehicle body 1, a fixing frame 6 fixedly connected to the top of the vehicle body 1, a first cylinder 7 fixedly connected to the fixing frame 6, a second cylinder 8 fixedly connected to the fixing frame 6, the second cylinder 8 being located in front of the first cylinder 7, a discharge gate 9 fixedly connected to the first cylinder 7, a first fixing block 10 fixedly connected to the second cylinder 8, and a feeding gate 11 slidably connected to the first fixing block 10. The limiting teeth of the discharge gate 9 and the feeding gate 11 are staggered to accommodate the position of the connection between two rows of adjacent honeycomb grids. The feeding gate 11 is slidably connected to the first slider 12, the first slider 12 is slidably connected to the fixing plate 13, and the first spring 14 is provided between the first slider 12 and the fixing plate 13. The pusher plate 4 is slidably connected to the honeycomb grid stretching mechanism 15 for stretching the last row of the honeycomb grid completely. The base plate 3 is rotatably connected to the guide limiting mechanism 16, which is symmetrically connected to guide and limit the two sides of the honeycomb grid. The vehicle body 1 is slidably connected to the guide limiting mechanism 16. The bottom of the vehicle body 1 is fixedly connected to the shaping limiting mechanism 17 for limiting and shaping the grid during the stretching process. The vehicle body 1 is fixedly connected to the filling mechanism 18 for uniformly filling soil into the honeycomb grid. The filling mechanism 18 is located behind the shaping limiting mechanism 17 and is used to uniformly fill soil into the honeycomb grid after it is shaped and spread out.

[0036] When using this device to lay honeycomb grid roadbed, the worker first flips up the flap 2, places the honeycomb grid on the base plate 3, inserts the last cell of the honeycomb grid into the honeycomb grid tensioning mechanism 15, and then starts the electric push rod 5 to push the pusher plate 4 to gradually push the honeycomb grid towards the feeding gate 11. In the initial state, the feeding gate 11 is in the position where the honeycomb grid is placed and limited, and the discharge gate 9 is in the raised position. The initial position of the limiting teeth of the discharge gate 9 is behind the limiting teeth of the feeding gate 11, and... The distance is the difference in front-to-back distance between two adjacent connection points in the folded state of the honeycomb grid. Because the grids of adjacent rows of the honeycomb grid are staggered, the limiting teeth of the feeding gate 9 and the limiting teeth of the feeding gate 11 are staggered to more accurately limit the honeycomb grid. When the honeycomb grid contacts and is pressed against the feeding gate 11, the electric push rod 5 pushes the honeycomb grid backward. At the same time, the honeycomb grid drives the feeding gate 11 and the first slider 12 to move backward. The feeding gate 11 slides relative to the first fixed block 10, and... The first slider 12 slides relative to the fixed plate 13, simultaneously stretching the first spring 14. When the limiting tooth of the feeding gate 11 moves to the front of the limiting tooth of the discharging gate 9, and the distance from it is the difference in the front-to-back distance between two adjacent connection points in the honeycomb grid folded state, the electric push rod 5 stops pushing the honeycomb grid backward, and the first cylinder 7 controls the discharging gate 9 to move downward. At this time, the limiting tooth of the discharging gate 9 just inserts into the next row of honeycomb grids to limit the subsequent honeycomb grids. Then, the second cylinder 8 controls the feeding gate 11 to move downward. The cylinder lifts the feed gate 9, releasing a row of honeycomb grids between the feed gate 9 and the feed gate 11. At the same time, the feed gate 11 loses the restriction of the honeycomb grids, and the feed gate 11 will reset due to the tension of the first spring 14. After the feed gate 11 is lifted to the highest position by the second cylinder 8, it has completed the forward movement and reset. Then, the second cylinder 8 drives the feed gate 11 to move down, limiting the next row of honeycomb grids that is currently restricting the feed gate 9. Then, the staff fixes the first row of grids that has been released.

[0037] The vehicle is then started and the above operation is repeated to release the honeycomb grid row by row. Due to the nature of the honeycomb grid, the distance between its two ends gradually decreases when the honeycomb grid is stretched. The stretching length of each row of honeycomb grid is inversely proportional to the width of each row of honeycomb grid. In order to adapt to road surfaces of different widths, it is necessary to control the width of the honeycomb grid by controlling the stretching length of each row of honeycomb grid. By controlling the feeding speed of the feeding gate 9 and the feeding gate 11 and the moving speed of the vehicle body 1, the honeycomb grid is stretched to a preset length so that the honeycomb grid reaches the preset width. When installing the honeycomb grid and placing it on the base plate 3, the operator installs the last row of honeycomb grid on the honeycomb grid stretching mechanism 15 to ensure that the whole device can stretch the last row of honeycomb grid to the preset state.

[0038] When releasing tension on multiple rows of honeycomb grids, the width of each row varies due to the different degrees of tension. The overall honeycomb grid arrangement is trapezoidal. Because the honeycomb grid is made of a soft material, a guide limiting mechanism 16 is needed to guide and limit the two sides of the honeycomb grid. At the same time, when stretching the honeycomb grid, the grids in the middle are stretched only by the tension of the row in front. However, the overall stretching process cannot guarantee that the tension of each grid is the same, so the degree of stretching of the grids in the middle cannot be guaranteed. Therefore, a shaping limiting mechanism 17 is used to limit and shape the grids of each row of honeycomb grids, and a soil filling mechanism 18 is used to fill the honeycomb grid after stretching. This directly covers the stretched honeycomb grid with soil and stone to fix it, eliminating the need for separate fixing of the honeycomb grid through other fixing methods.

[0039] Example 2 Based on Example 1, such as Figures 6-8 As shown, the honeycomb mesh stretching mechanism 15 includes a second slider 1501, which is slidably connected to the pusher plate 4. A first fixing rod 1502 is fixedly connected to the second slider 1501. A first scissor-type telescopic frame 1503 is fixedly connected to the bottom of the first fixing rod 1502. The second slider 1501 is connected to the first scissor-type telescopic frame 1503 at equal intervals. An insert rod 1504 is slidably connected to the second slider 1501. A second spring 1505 is provided between the second slider 1501 and the insert rod 1504. The rear end of the insertion rod 1504 is rotatably connected to a limiting hook 1506. An elastic tab is provided between the limiting hook 1506 and the insertion rod 1504. The tensile elastic coefficient of the elastic tab is greater than the elastic coefficient of the second spring 1505. As the elastic force of the second spring 1505 increases, the elastic tab gradually deforms, and the limiting hook 1506 gradually swings backward synchronously until it loses its limiting effect on the honeycomb grid holes. The limiting hook 1506 has a wedge-shaped structure, and the holes of the honeycomb grid are fixed by the cooperation of the limiting hook 1506 and the elastic tab.

[0040] When the entire device is in operation, the honeycomb grid stretching mechanism 15 limits the last row of the honeycomb grid. Because the honeycomb grid has small holes, the operator separates the last row of honeycomb grid so that the insertion rod 1504 is inserted into the holes of the last row of honeycomb grid. The limiting hook 1506 is equipped with an elastic tab. When passing through the holes of the honeycomb grid, the limiting hook 1506 swings backward. After passing through the holes of the limiting hook 1506, it returns to its original position through the elastic tab. Due to the action of the elastic tab, the limiting hook 1506 will then have a self-locking effect on the honeycomb grid. When the last row of honeycomb grid is released, the honeycomb grid drives the insertion rod 1504 to slide backward, and the second spring 1505 is compressed. During the movement, the honeycomb grid fixed by the insertion rod 1504 will synchronously contract inward. At this time, the honeycomb grid pulls the honeycomb grid. The second slider 1501 slides in the groove of the pusher plate 4. The second slider 1501 drives the first fixed rod 1502 to move simultaneously. The first fixed rod 1502 drives the first scissor-type telescopic frame 1503 to move, so that the distance between the second sliders 1501 changes proportionally, thereby restricting the shape of the honeycomb grid. When the honeycomb grid is stretched, the limiting hook 1506 continues to limit the honeycomb grid holes under the action of the elastic plate. As the elastic force of the second spring 1505 increases, the elastic plate gradually deforms, and the limiting hook 1506 gradually swings backward synchronously until it loses the limitation on the honeycomb grid holes. At this time, the honeycomb grid has been delivered by the honeycomb grid stretching mechanism 15 to the shaping limiting mechanism 17 to prevent the honeycomb grid from undergoing free deformation when moving in the guide limiting mechanism 16.

[0041] like Figure 9 and Figure 10 As shown, the guide limiting mechanism 16 includes a symmetrically distributed first limiting plate 1601, which is symmetrically rotatably connected to the base plate 3 on the left and right sides. The first limiting plate 1601 is provided with a first sliding groove 1602. The end of the first limiting plate 1601 away from the base plate 3 is rotatably connected to a second limiting plate 1603. The second limiting plate 1603 is slidably connected to a third limiting plate 1604. The third limiting plate 1604 is fixedly connected to a second fixing rod 1605. The second fixing rod 1605 is slidably connected to the vehicle body 1. The second fixing rod 1605 is fixedly connected to a bidirectional cylinder 1606.

[0042] During the stretching process of the honeycomb grid, a guide limiting mechanism 16 is used to guide and limit the two ends of the honeycomb grid to prevent the honeycomb grid from being laid skewed. First, the bidirectional cylinder 1606 is activated to move the third limiting plates 1604 on both sides inward until the required width of the honeycomb grid is reached, after which the bidirectional cylinder 1606 stops moving. During this process, the third limiting plate 1604 drives the second limiting plate 1603 to move inward together. The second limiting plate 1603 drives the first limiting plate 1601 to rotate around the end away from the second limiting plate 1603 as the center. At the same time, the second limiting plate 1603 and the first limiting plate 1601 rotate relative to each other. The first limiting plate 1601 drives the second limiting plate 1603, causing the second limiting plate 1603 and the third limiting plate 1604 to slide relative to each other. At this time, the first... The shape formed by the limiting plate 1601, the second limiting plate 1603, and the third limiting plate 1604 is precisely the transition shape for the intermediate state during the stretching of the honeycomb grid. The first limiting plate 1601, the second limiting plate 1603, and the third limiting plate 1604 play a limiting role in the overall shape of the honeycomb grid during stretching. When the honeycomb grid is stretched from the substrate 3 to the first limiting plate 1601, it will lose the support of the substrate 3 and fall to the ground. The bottom surface of the discharge side of the first limiting plate 1601 is lower than the bottom surface of the infeed side, which limits the honeycomb grid during the entire placement process. The closer the distance between the two second limiting plates 1603, the greater the stretching of the honeycomb grid. The farther the distance between the two second limiting plates 1603, the smaller the stretching of the honeycomb grid.

[0043] like Figure 5 and Figures 10-13As shown, the shaping and limiting mechanism 17 includes a third slider 1701, which is slidably connected to a first groove 1602. The third slider 1701 is ball-connected to a first fixing ring 1702. The first fixing ring 1702 is rotatably connected to a limiting wheel 1703. The limiting wheel 1703 is slidably connected to a splined shaft 1704. The splined shaft 1704 has second grooves 1711 evenly spaced, with the depth of the second grooves gradually decreasing towards the center of the splined shaft 1704. The splined shaft 1704 has limiting wheels 1703 evenly spaced. The vehicle body 1 is fixedly connected to a third fixing rod 1705, which is rotatably connected to the splined shaft 1704. The limiting wheel 1703 is rotatably connected to a second fixing ring 1706, which is fixedly connected to a second scissor-type telescopic frame 1707. The vehicle body 1 is fixedly... A fourth fixed rod 1708 is fixedly connected to the second scissor-type telescopic frame 1707. The fourth fixed rod 1708 limits the telescopic direction of the second scissor-type telescopic frame 1707. The second scissor-type telescopic frame 1707 drives the limiting wheel 1703 to adjust the distance proportionally. The limiting wheel 1703 is slidably connected to the limiting piece 1709. The limiting piece 1709 is slidably engaged with the adjacent second slide groove 1711. The depth of the second slide groove 1711 limits the protrusion length of the limiting piece 1709. When the stretching degree of the honeycomb grid is large, the distance between the two adjacent rows of grids increases accordingly, and the limiting piece 1709 protrudes a longer distance to facilitate grid positioning. The opposite is true when the stretching degree of the honeycomb grid is small. A third spring 1710 is provided between the limiting wheel 1703 and the limiting piece 1709.

[0044] During the honeycomb grid stretching process, the grids in the middle of the honeycomb grid are stretched only by the tension of the row in front. However, the overall stretching process cannot guarantee that the tension of each grid is the same, so the stretching degree of the grids in the middle of the honeycomb grid cannot be guaranteed. Therefore, the shaping and limiting mechanism 17 can limit and shape the grids of each row of honeycomb grids. When the first limiting plate 1601 is adjusted, the first limiting plate 1601 will drive the third slider 1701 to slide in the first slide groove 1602 and retract inward at the same time. At this time, the third slider 1701 drives the first fixing ring 1702 to move along the spline shaft 1704 towards the center position of the spline shaft 1704. The first fixing ring 1702 drives the parts on it to move inward synchronously. At this time, several limiting wheels 1703 on the spline shaft 1704 will move inward proportionally due to the second scissor-type telescopic frame 1707. When sliding inward, the limiting piece 1709 The limiting plate 1709 will extend outward due to the limiting of the second slide 1711. The longer the inward movement, the longer the extension distance of the limiting plate 1709 will also increase, while compressing the third spring 1710. When the two first limiting plates 1601 return to parallel, the third spring 1710 will drive the limiting plate 1709 to reset. The more the limiting wheel 1703 moves inward, the greater the deflection angle of the first limiting plate 1601, that is, the greater the distance between two adjacent rows of honeycomb grid. The extension of the limiting plate 1709 can accurately position each row of honeycomb grid. When the honeycomb grid passes through the shaping limiting mechanism 17, the honeycomb grid will drive the limiting wheel 1703 to rotate. The limiting wheel 1703 drives the spline shaft 1704 to rotate. The rotation resistance of the limiting wheel 1703 will generate a pulling force on the movement of the honeycomb grid. Since the rotation resistance of the limiting wheel 1703 remains unchanged, the pulling force on the honeycomb grid is uniform, thereby achieving a stable shaping effect of the honeycomb grid.

[0045] like Figure 5 , Figure 9 and Figures 14-16The backfilling mechanism 18 includes a storage bin 1801, which is fixedly connected to the vehicle body 1. A discharge pipe 1802 is fixedly connected to the bottom of the storage bin 1801. A distribution shell 1803 is fixedly connected to the outlet of the discharge pipe 1802. A crushing roller 1804 is rotatably connected to the distribution shell 1803, and a distribution auger 1805 is rotatably connected to the distribution shell 1803. A motor 1806 is installed on the vehicle body 1. The output shaft of the motor 1806 is fixedly connected to the distribution auger 1805. The output shaft of the motor 1806 is connected to the crushing roller 1804 via a pulley belt. A discharge shell 1807, which communicates with the distribution shell 1803, is fixedly connected to the vehicle body 1. A screen plate 1808 is fixedly connected inside the discharge shell 1807. The screen plate 1808 pre-screens out some fine particles of soil and rock, which are then pre-laid on the contact area between the honeycomb grid and the ground. This design helps reduce the gap between the honeycomb grid and the ground, improving the fixation effect of the honeycomb grid. The material feeding shell 1807 is rotatably connected to a telescopic plate 1809, which is rotatably connected to a first limiting baffle 1810. The first limiting baffle 1810 is used to limit the left and right direction of the upper layer of soil and stone. The first limiting baffle 1810 is fixedly connected to a second limiting baffle 1811, which is used to limit the left and right direction of the lower layer of soil and stone. This allows for equal-width backfilling in accordance with the laying width of the honeycomb grid. The front end of the second limiting baffle 1811 is fixedly connected to a second fixing block 1812, which is fixedly connected to a third limiting plate 1604. The material feeding shell 1807 is rotatably connected to a flat-laying auger 1813, and the output shaft of the motor 1806 is connected to the flat-laying auger 1813 via a pulley and belt.

[0046] After the honeycomb grid is stretched, when backfilling, the soil and rocks in the storage bin 1801 enter the equalization shell 1803 through the discharge pipe 1802. The motor 1806 drives the crushing roller 1804 to crush the lumpy soil while preventing the soil and rocks in the discharge pipe 1802 from clogging. After entering the equalization shell 1803, the soil and rocks are evenly distributed by the equalization auger 1805. After distribution, the soil and rocks enter the discharge shell 1807. The evenly distributed soil and rocks are screened by the screen plate 1808, which screens out some fine soil particles. Some fine soil and rocks are pre-laid at the bottom of the honeycomb grid. This helps to reduce the laying gap between the honeycomb grid and the ground, and the honeycomb grid subgrade will be more solid during compaction. The guide limit mechanism 16 is adjusted to limit the honeycomb grid. When the soil and rock are laid, the third limiting plate 1604 will drive the second fixing block 1812 to move towards the center at the same time. The second fixing block 1812 will drive the second limiting baffle 1811 to move. The second limiting baffle 1811 will drive the first limiting baffle 1810 to move. The first limiting baffle 1810 will drive the telescopic plate 1809. The telescopic plate 1809 and the material feeding shell 1807 will rotate and stretch the telescopic plate 1809 at the connection point. This will adjust the falling range of the soil and rock so that the falling range of the soil and rock is the same as the laying width of the honeycomb grid. This will ensure that the width of the laid soil and rock does not differ too much from the laying width of the honeycomb grid, reducing the workload of subsequent work. After the soil and rock are laid, the laying auger 1813 will flatten the laid soil and rock, which will facilitate the development of subsequent work.
