Description

Technical Field

[0001] The present application relates to the technical field of brick-laying devices, and in particular to an automatic brick-laying device and method for a sidewalk. Background Art

[0002] Road construction is an important part of urban infrastructure construction, and sidewalk construction is directly related to the safety and comfort of citizens' daily travel. After the sidewalk is completed, in order to enhance its durability, aesthetics and ease of maintenance, large concrete bricks are usually used to pave the sidewalk surface. This paving method can not only improve the bearing capacity of the sidewalk, but also effectively prevent the foundation from sinking due to rainwater penetration. At the same time, the uniform concrete bricks can also add a sense of cleanliness and beauty to the city.

[0003] In existing road construction, the task of laying large concrete bricks on the sidewalk surface is mainly done manually. During this process, workers need to manually carry, arrange and fix bricks to ensure that each brick fits tightly, is flat and has no gaps. In order to ensure the quality of laying, workers also need to use professional tools to knock and adjust the bricks to achieve the flatness and firmness required by the design. In addition, for the gaps generated during the laying process, workers also need to perform meticulous caulking to ensure the overall beauty and durability of the sidewalk.

[0004] However, although the manual paving method can meet the needs of sidewalk surface paving to a certain extent, its low efficiency cannot be ignored; manual paving is not only time-consuming and labor-intensive, but also easily affected by various factors such as workers' skill level, physical condition and weather conditions, making it difficult to effectively guarantee the paving progress and quality. Summary of the invention

[0005] The purpose of the present application is to provide an automatic brick-laying device and method for a sidewalk, so as to solve the problem of low efficiency in laying large concrete bricks on the sidewalk in the above-mentioned related technologies.

[0006] In the first aspect, the present application provides an automatic sidewalk paving device that adopts the following technical solution:

[0007] An automatic brick-paving device for sidewalks comprises a vehicle body with an opening on the upper side, a plurality of wheels mounted on the bottom side of the vehicle body and a driving member fixedly provided for driving the wheels to move; a support plate fixedly provided on the outside of the vehicle body, a vacuum suction cup for clamping bricks and a power member for driving the vacuum suction cup to move are arranged on the support plate; a first visual sensor for sensing the brick laying position is fixedly provided on the support plate, and a second visual sensor for detecting the brick clamping situation is fixedly provided on the vehicle body; a clearance gap for bricks to be loaded into the vehicle body is provided on the vertical side surface of the vehicle body away from the support plate, and a sealing plate is detachably installed on the inner wall of the clearance gap.

[0008] By adopting the above technical solutions, the device not only greatly improves the laying efficiency and reduces the labor intensity, but also ensures the stability of the laying quality. The first visual sensor accurately locates the masonry laying position, and the second visual sensor monitors the masonry clamping status in real time, and the double guarantee ensures the accuracy of the laying. In addition, the clearance gap design on the side of the vehicle body, combined with the detachable blocking plate, not only facilitates the rapid loading of bricks, but also provides great convenience for the daily maintenance and overhaul of the equipment. The application of this device effectively solves the problems of low efficiency and unstable quality of manual laying.

[0009] Optionally, two symmetrical positioning rods are fixedly provided on the lower side of the support plate, and an extrusion roller is provided on the outside of the vehicle body. Both ends of the extrusion roller are respectively hinged to the lower ends of the two positioning rods, and the extrusion roller is flush with the lowest point of the outer circumference of the wheel.

[0010] By adopting the above technical solution, when the automatic brick-laying device for the sidewalk moves to the position of the unpaved road surface, the squeezing rollers connected to the two symmetrical positioning rods fixed on the lower side of the support plate can roll closely against the unpaved road surface, and the rolling behavior of the squeezing rollers helps to pre-level the unpaved road surface, laying a good foundation for the subsequent brick laying, and ensuring that the paved road surface is smoother;

[0011] Optionally, a limit plate is fixedly provided on the side of the support plate away from the positioning rod, and a limit notch is provided on the vertical side of the vehicle body away from the blocking plate, and the side edge of the support plate close to the vehicle body is hinged to the inner wall of the limit notch; the limit plate rotates into the limit notch when the positioning rod is in a vertical downward state, and the support plate rotates into the limit notch when the positioning rod is in a horizontal state, and a locking member for detachably locking the vertical limit plate and the support plate is provided on the outside of the vehicle body.

[0012] By adopting the above technical solution, when the positioning rod is in a vertical downward state, the limit plate can be cleverly rotated into the limit gap and locked by the locking piece. At this time, the extrusion roller is close to the road surface, which is convenient for the smooth movement of the device and can effectively compact the road surface during the brick paving process; after the brick paving device has completed laying the bricks, the support plate is rotated into the limit gap and locked by the locking piece. At this time, the vacuum suction cup and the corresponding power part are rotated into the vehicle body for storage, thereby reducing the overall volume of the brick paving device and facilitating the long-distance transportation of the brick paving device.

[0013] Optionally, the locking member includes a locking rod, a first spring and a control member, a locking hole for the locking rod to pass through is provided on the vehicle body, a first slot is provided on the limit plate, and a second slot is provided on the support plate; a baffle is fixedly provided on the outer periphery of the locking rod, a locking groove for the baffle to be inserted into is provided on the opening edge of the locking hole close to the outside of the vehicle body, and the two ends of the first spring are respectively fixedly connected to the bottom side of the locking groove and the inner side surface of the baffle; the control member is used to drive the locking rod to reciprocate in the direction close to the vehicle body, the locking rod passes through the locking hole and is inserted into the first slot when the limit plate is turned into the limit notch, and passes through the locking rod and is inserted into the second slot when the support plate rotates the limit notch.

[0014] By adopting the above technical solution, when the limit plate or the support plate is rotated into the limit notch, the locking rod can automatically pop out and insert into the corresponding slot, and the locking state is maintained by the elastic force of the first spring, effectively preventing the limit plate and the support plate from accidentally shaking or shifting during the movement or laying process. At the same time, the design of the control part enables the locking rod to be easily unlocked and re-locked, which is convenient for operation and adjustment.

[0015] Optionally, the lower edge of the blocking plate is hinged to the inner wall of the clearance gap, and the upper edge of the vehicle body close to the clearance gap is hinged with a locking plate, and the rotation surface of the locking plate is parallel to the horizontal plane; when the blocking plate is in a vertical state, its upper side surface is flush with the upper side surface of the vehicle body, and the lower side surface of the locking plate can abut against the upper side surface of the blocking plate when the blocking plate is rotated to a vertical state

[0016] By adopting the above technical solution, the hinged design of the lower edge of the blocking plate and the inner wall of the clearance gap allows the blocking plate to be easily switched between the vertical state and the horizontal state, which is convenient for loading bricks and maintaining the equipment. When the blocking plate is in the vertical state, its upper side is flush with the upper side of the vehicle body, maintaining the neatness and uniformity of the appearance of the device. At the same time, the locking plate hinged to the upper edge of the vehicle body near the clearance gap can be tightly abutted against the upper side of the blocking plate when the blocking plate is rotated to the vertical state, achieving a stable lock, effectively preventing the blocking plate from accidentally opening during movement or laying, and ensuring the safety and stability of the bricks inside the device.

[0017] Optionally, the control member includes an extension rod fixedly provided on the outer surface of the blocking plate in a horizontal direction and a control rod slidably provided on the outside of the vehicle body in a horizontal direction, and the extension rod is perpendicular to the length direction of the control rod; a connecting rod is provided on the outside of the vehicle body, and both ends of the connecting rod are respectively hinged to the ends of the extension rod and the control rod close to each other, and a guiding inclined surface is provided on the outer end edge of the locking rod; when the blocking plate rotates into the clearance gap, the control rod is squeezed against the locking rod along the guiding inclined surface, and the control rod is misaligned with the locking rod after the blocking plate rotates out of the clearance gap.

[0018] By adopting the above technical solution, the articulated cooperation between the extension rod and the control rod, as well as the connection function of the connecting rod, enable the control rod to extrude the locking plug along the guiding inclined plane when the plugging plate rotates, realizing the automatic unlocking or locking of the locking plug. This design not only simplifies the operation process and improves work efficiency, but also ensures the safety and stability of the plugging plate during the opening or closing process.

[0019] Optionally, two symmetric handles are fixedly arranged on the side of the plugging plate away from the vehicle body, and the side of the handle away from the plugging plate can abut against the ground when the plugging plate rotates outward to the horizontal state.

[0020] By adopting the above technical solution, the two symmetric handles fixedly arranged on the side of the plugging plate away from the vehicle body not only provide a convenient force application point for the operator, enabling the plugging plate to easily switch between the vertical and horizontal states, but also when the plugging plate rotates outward to the horizontal state, the side of the handle can abut against the ground, playing a role in supporting and stabilizing the plugging plate, preventing the plugging plate from suddenly falling due to gravity, and ensuring the safety during the operation process.

[0021] Optionally, the power component includes a rotating base rotatably arranged on the upper side of the support plate. A first vertical plate is fixedly arranged on the rotating base along the vertical direction. A second horizontal plate is slidably arranged on the first vertical plate and can slide up and down along the horizontal direction. A vertical cylinder with a vertically downward piston rod is slidably arranged on the second horizontal plate and can slide horizontally. The vacuum suction cup is fixedly arranged at the end of the piston rod of the vertical cylinder. A first driving source for driving the rotating base to rotate is arranged at the bottom side of the support plate. A second driving source for driving the second horizontal plate to slide is arranged on the first vertical plate. A third driving source for driving the vertical cylinder to slide is arranged on the second horizontal plate.

[0022] By adopting the above technical solution, the combination of the rotating base, the first vertical plate, the second horizontal plate and the vertical cylinder forms a multi-degree-of-freedom motion system, enabling the vacuum suction cup to freely move in three-dimensional space and easily realizing the clamping and laying of bricks at different positions and angles. At the same time, the independent arrangement of the first driving source, the second driving source and the third driving source provides sufficient power support for each motion direction, ensuring the stability and accuracy of the operation.

[0023] Optionally, a tray is arranged inside the vehicle body. A plurality of installation grooves for the bricks to be inserted are evenly opened on the upper side of the tray. An elastic pad is fixedly arranged on the upper side of the tray. The limiting plate can turn to the horizontal state and abut against the elastic pad when the support plate turns into the limiting notch. A shock-absorbing pad is fixedly arranged at the end of the second horizontal plate close to the first vertical plate, and the shock-absorbing pad can abut against the upper side of the limiting plate in this state when the support plate turns into the limiting notch.

[0024] By adopting the above technical solution, after the brick-laying device has finished laying the bricks, the support plate is rotated into the limiting notch and locked by the locking member. At this time, the side of the limiting plate away from the supporting plate can be rotated to a horizontal state and abut against the elastic pad. The state of the second cross plate is adjusted so that the shock-absorbing pad on the second cross plate abuts against the upper side of the limiting plate in this state. The driving member is supported by the second cross plate, and the combination of the shock-absorbing pad and the elastic pad is used to reduce the possibility of damage to the limiting plate and the second cross plate due to collision.

[0025] In the second aspect, the present application provides a method for automatic brick paving of a sidewalk using the following technical solution:

[0026] A method for automatically paving sidewalks, using the above-mentioned automatic sidewalk paving device, comprises the following steps:

[0027] Step 1: Fill the pallet with bricks and stones in advance, unlock the blocking plate and the support plate, flip the blocking plate and the support plate outward to a horizontal state, unblock the clearance gap, and use a forklift to place the pallet through the clearance gap into the vehicle body;

[0028] Step 2: Flip the blocking plate upward and lock it, and drive the locking rod to move through the control member to lock the limiting plate that is rotated into the limiting notch;

[0029] Step 3: During the laying process, according to the signals detected by the first visual sensor and the second visual sensor, the vehicle body is driven to move by the driving member, and the vacuum suction cup is driven by the power member to clamp and lay the bricks;

[0030] Step 4: After laying, first release the lock of the blocking plate and the limiting plate, and flip the blocking plate outward to a horizontal state; then adjust the state of the second horizontal plate so that the shock-absorbing pad can abut against the upper side of the limiting plate in this state when the supporting plate turns into the limiting gap; then rotate the supporting plate upward into the limiting gap, and turn the blocking plate upward into the clearance gap and lock it.

[0031] By adopting the above technical solution and using a specially designed automatic brick-laying device for sidewalks, the brick-laying process is efficiently, automatically and precisely controlled. This method not only simplifies the tedious manual operation in traditional brick-laying operations and improves work efficiency, but also ensures the accuracy of the laying position through precise detection by the first visual sensor and the second visual sensor. At the same time, the bricks are clamped and laid using vacuum suction cups, which further improves the flatness and firmness of the laying. In addition, this method also focuses on the flexible adjustment and firm locking of the device, ensuring the safety and stability of the entire brick-laying process.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. This device not only greatly improves the laying efficiency and reduces the labor intensity, but also ensures the stability of the laying quality. The first visual sensor accurately locates the masonry laying position, and the second visual sensor monitors the masonry clamping status in real time. The double guarantee ensures the accuracy of the laying. In addition, the design of the clearance gap on the side of the vehicle body, combined with the detachable blocking plate, not only facilitates the rapid loading of bricks, but also provides great convenience for the daily maintenance and overhaul of the equipment. The application of this device effectively solves the problems of low efficiency and unstable quality of manual laying.

[0034] 2. When the positioning rod is in a vertical downward state, the limit plate can be cleverly turned into the limit gap and locked by a locking piece. At this time, the extrusion roller is close to the road surface, which is convenient for the smooth movement of the device and can effectively compact the road surface during the paving process. After the brick-laying device has completed laying the bricks, the support plate is turned into the limit gap and locked by a locking piece. At this time, the vacuum suction cup and the corresponding power parts are rotated into the vehicle body for storage, which reduces the overall volume of the brick-laying device and facilitates the long-distance transportation of the brick-laying device.

The side edge of the support plate 21 close to the vehicle body 1 is hinged to the inner wall of the limiting notch 15;

[0056] When the positioning rod 23 is in the vertically downward state, the limiting plate 25 rotates into the limiting notch 15; when the positioning rod 23 is in the horizontal state, the support plate 21 rotates into the limiting notch 15; two locking members 6 for detachably locking the limiting plate 25 and the support plate 21 in the vertical state are symmetrically arranged on the two opposite vertical side surfaces of the vehicle body 1.
