Description

Technical Field

[0001] The present application relates to the technical field of municipal road construction equipment, and in particular to an intelligent municipal road construction equipment. Background Art

[0002] Municipal engineering refers to the construction of municipal facilities, such as common urban roads, bridges, and subways. Some municipal roads (such as sidewalks) require paving with floor tiles. After the tiles are laid, they need to be manually compacted. Manual compaction is not only inefficient and increases the labor intensity of workers, but also increases construction costs.

[0003] Chinese patent publication number CN113152226A discloses an intelligent municipal road construction device, comprising a vehicle body and a compacting mechanism. The vehicle body comprises a vehicle plate, four running wheels, a carriage, and handrails. The compacting mechanism comprises a compacting plate, a power rod, a drive assembly, and a buffer assembly. The drive assembly comprises a drive plate horizontally fixed to the upper end of the power rod, a drive wheel rotatably disposed within the carriage and in contact with the upper end surface of the drive plate, a drive member fixed within the carriage to drive the drive wheel, and a drive spring sleeved around the power rod. The axis of the drive wheel is arranged horizontally. One end of the drive spring is fixed to the vehicle body, and the other end is fixed to the power rod. The drive spring constantly applies a vertical upward force to the power rod. While controlling the vehicle body to move on the municipal road, the power rod drives the compacting plate to move up and down repeatedly, thereby compacting the floor tiles laid on the municipal road.

[0004] When the intelligent municipal road construction device is in operation, the lifting assembly controls the vertical position of the compacting mechanism relative to the vehicle body, thereby controlling the force applied by the compacting mechanism to the tiles. However, the lifting assembly's control over the compacting mechanism's compaction effect is not precise, and the lifting assembly bears most of the gravity when the compacting mechanism is not compacting and the force applied when the compacting mechanism is compacting. This seriously affects the reliability of the lifting assembly and, consequently, the compacting mechanism's compaction effect on the tiles. Summary of the Invention

[0005] The present application provides an intelligent municipal road construction device, which can improve the efficiency of floor tile compaction while facilitating construction personnel to more accurately control the force of the construction device in compacting the floor tiles during the compaction operation, thereby further improving the floor tile compaction effect and improving the stability and reliability of the construction device in the process of compacting the floor tiles.

[0006] This application provides an intelligent municipal road construction device, which adopts the following technical solutions:

[0007] The treadmill is a road-moving vehicle according to claim 1, wherein the treadmill is a road-moving vehicle having a plurality of moving parts and a plurality of moving parts. The treadmill is a road-moving vehicle having a plurality of moving parts and a plurality of moving parts. The treadmill is a road-moving vehicle having a plurality of moving parts and a plurality of moving parts. The treadmill is a road-moving vehicle having a plurality of moving parts and a plurality of moving parts. The treadmill is a road-moving vehicle having a plurality of moving parts and a plurality of moving parts. The treadmill is a road-moving vehicle having a plurality of moving parts and a plurality of moving parts.

[0008] The compacting mechanism also includes a regulating component for controlling the compacting force. The driving wheel is movable inside the vehicle body. The regulating component controls the movement of the driving wheel relative to the power rod, and after the position of the driving wheel changes, the power rod still remains in contact with the driving wheel.

[0009] By adopting the above technical solution, the first driving member drives several driving wheels to rotate, and the rotation of the driving wheels and the reset member work together to drive the power rod to move back and forth in the vertical direction. After the power rod moves downward to drive the tamping plate to resist the floor tiles, the power rod continues to move downward to extrude the elastic member so that the tamping plate has a downward force on the floor tiles, thereby compacting the floor tiles. The force exerted by the tamping mechanism in the process of compacting the floor tiles will be directly borne by the vehicle body, which can reduce the workload of the tamping mechanism, thereby improving the stability and reliability of the construction device in the process of compacting the floor tiles; the power rod moves upward to drive the tamping plate to separate from the floor tiles, so that the tamping plate repeatedly compacts the floor tiles; after the regulating component controls the movement of the driving wheel to change the relative position between the driving wheel and the power rod, the sliding stroke of the power rod will change, thereby changing the magnitude of the force transmitted to the floor tiles by the power rod through the tamping plate, thereby facilitating more precise control of the force exerted by the construction device on the floor tiles during the compaction operation, thereby further improving the compaction effect of the floor tiles.

[0010] Optionally, the regulating component includes a second driving member, the driving component is slidably connected to the vehicle body, the sliding direction of the driving component is perpendicular to the rotation axis of the driving wheel, and the second driving member drives the driving component to slide.

[0011] By adopting the above technical solution, after the control and regulating assembly drives the driving assembly to slide as a whole, the rotation axis of the driving wheel and the axis of the power rod are offset in the horizontal direction. At this time, the rotation of the driving wheel can still drive the power rod to slide and drive the tamping plate to resist and apply force to the floor tiles, but the change in the stroke of the power rod will also cause the magnitude of the force applied by the tamping plate to the floor tiles to change; when the rotation axis of the driving wheel is located directly above the axis of the power rod, the stroke of the power rod is the largest, that is, the tamping force of the tamping plate on the floor tiles is the largest, and the tamping force of the tamping plate on the floor tiles will decrease as the offset distance of the driving wheel increases, thereby making it convenient for construction personnel to use the control assembly.

[0012] Optionally, the regulating component includes a third driving member, the cross-sectional dimension of the driving wheel in the radial direction changes along the direction of its own rotation axis, several of the driving wheels are movable relative to the first driving member along the direction of their own rotation axis, and the third driving member drives the driving wheels to move.

[0013] By adopting the above technical solution, after the control and regulating component drives several driving wheels to move along their own rotation axis direction relative to the first driving member, the contact position of the driving wheel with the upper end of the power rod changes during the rotation process. At this time, the rotation of the driving wheel can still drive the power rod to slide and drive the tamping plate to resist and apply force to the floor tiles, but the change in the stroke of the power rod will also cause the magnitude of the force applied by the tamping plate to the floor tiles to change; the size of the cross-sectional size of the position on the driving wheel that contacts the power rod is related to the stroke of the power rod, thereby making it convenient for construction personnel to use the control component.

[0014] Optionally, the tamping mechanism further comprises a plurality of abutment plates, wherein the abutment plates are fixedly connected to the upper end of the power rod, and the upper end of the abutment plates has an abutment surface, and the driving wheel abuts against the abutment surface;

[0015] The trajectory of the position where the abutting surface abuts against the driving wheel is an arc, and the tangent slope of the arc gradually decreases along the direction from the bottom of the arc to the top of the arc.

[0016] By adopting the above technical solution, when the driving wheel rotates to drive the power rod to move downward, the driving wheel first abuts against the abutment surface near the bottom of the arc, and then the position where the driving wheel abuts against the abutment surface gradually changes until the abutment surface is near the top of the arc. During this process, the speed at which the power rod moves downward will gradually decrease, so that the power rod can slowly apply force to the floor tiles through the tamping plate and the force gradually increases, thereby reducing the probability of damage or failure of the tamping mechanism due to excessive force.

[0017] Optionally, it also includes a display screen and several buttons for controlling the driving component and the regulating component, and the display screen and several buttons are all arranged on the surface of the vehicle body; the tamping mechanism also includes a pressure sensor, and the pressure sensor is arranged on the tamping plate, and the pressure sensor is located between the elastic member and the tamping plate; the value detected by the pressure sensor is displayed on the display screen.

[0018] By adopting the above technical solution, construction personnel can control the driving component and the regulating component through buttons, which is convenient for the use of the construction device; and during the use of the construction device, the pressure sensor can present the force exerted by the power rod on the tamping plate in a numerical form on the display screen, so that construction personnel can know the size of the tamping force of the tamping plate on the floor tiles in real time through the display screen, and thus know the tamping effect of the tamping plate on the floor tiles, and then make it convenient for construction personnel to use the regulating component to adjust the tamping effect of the tamping plate on the floor tiles according to different needs.

[0019] Optionally, the tamping mechanism also includes a limiting assembly, which includes a limiting member and a fourth driving member. The power rod has a limiting portion on its peripheral side, the limiting member is located below the limiting portion, and the limiting member is movable in a vertical direction relative to the vehicle body, and the fourth driving member drives the limiting member to move.

[0020] By adopting the above technical solution, the limit assembly controls the movement of the limit member through the fourth driving member to limit the limit position of the downward movement of the power rod, thereby limiting the magnitude of the force applied by the power rod to the tamping plate, and further limiting the magnitude of the tamping force of the tamping plate on the floor tiles; in the process of adjusting the magnitude of the tamping force of the tamping plate on the floor tiles, the limit assembly is first controlled with reference to the numerical value detected by the pressure sensor on the display screen to limit the movement of the power rod until the numerical value on the display screen is the required value. At this time, the limit part on the power rod is kept against the limit member under the action of the driving assembly, and then the regulating assembly is controlled to make the driving wheel move until the driving wheel can continue to rotate. At this time, the position of the driving wheel can meet the requirement that the limit part of the power rod is against the limit member during its rotation, which is the limit position of the downward movement of the power rod, that is, the adjustment of the magnitude of the tamping force of the tamping plate on the floor tiles is completed; subsequently, the limit assembly is controlled to reset the limit member, which can facilitate construction personnel to quickly and accurately adjust the tamping force of the tamping plate on the floor tiles according to needs, so that the tamping plate can achieve the best tamping effect on the floor tiles.

[0021] Optionally, the movement of the limiting member is limited. When the limiting member moves upward to the limit position and the limiting portion abuts against the limiting member, there is a distance between the tamping plate and the floor tiles.

[0022] By adopting the above technical solution, when the tamping mechanism does not need to work, the limit assembly is controlled to move the limit part upward to the extreme position, and the limit part is abutted against the limit part, thereby separating the tamping plate from the floor tiles, facilitating the movement of the vehicle body; at this time, the limit part supports the support rod and the tamping plate, which can reduce the workload of the reset part, thereby reducing the probability of the reset part's performance being degraded due to long-term reset of the support rod and the tamping plate, thereby extending the service life of the reset part and improving the position stability of the tamping plate relative to the vehicle body when the tamping mechanism does not need to work.

[0023] Optionally, it also includes a power supply mechanism and a moving mechanism for driving the construction device to move. The power supply mechanism is arranged inside the vehicle body, the moving mechanism is arranged at the bottom of the vehicle body, and the moving mechanism and the compacting mechanism are respectively close to the two ends of the vehicle body.

[0024] By adopting the above technical solution, the moving mechanism is used to drive the movement of the vehicle body and other components, and the power supply mechanism provides energy support for the moving mechanism, etc., so that the construction device does not require an external power supply during short-term operations, which facilitates the use of the construction device; and during the use of the construction device, the moving mechanism is kept on the compacted floor tiles, and the compacting mechanism then compacts the uncompacted floor tiles, thereby further improving the effect of the construction device on compacting the floor tiles.

[0025] Optionally, a driver's seat is further included, which is arranged on the top of the vehicle body, and the position of the driver's seat on the vehicle body is close to the tamping mechanism.

[0026] By adopting the above technical solution, during the process of using the construction device to compact the floor tiles, the construction personnel can control the construction device on the driver's seat, and the construction device can move with the movement of the vehicle body, thereby reducing the workload of the construction personnel; at the same time, after the construction personnel are in position on the driver's seat, the center of gravity of the entire construction device will shift toward a position close to the compacting mechanism, thereby reducing the probability of the end of the vehicle body close to the compacting mechanism being lifted up due to the reaction force during the operation of the compacting mechanism, thereby reducing the impact of the above situation on the compacting effect of the construction device on the floor tiles.

[0027] Optionally, the moving mechanism includes a track assembly, a fifth drive member and a sixth drive member, the track assembly is rotatably connected to the vehicle body, the rotation axis of the track assembly is vertical, the track assembly is located below the vehicle body and in contact with the floor tiles; the fifth drive member is arranged inside the vehicle body, the fifth drive member drives the track assembly to rotate; the sixth drive member is arranged on the track assembly, and the sixth drive member drives the track assembly to work.

[0028] By adopting the above technical solution, the construction device as a whole is moved by the crawler assembly, which can improve the stability of the movement of the construction device, and at the same time can expand the contact area of ​​the construction device with the floor tiles during the movement, reduce the pressure of the construction device's own weight on the floor tiles, and thus reduce the impact of the construction device's own weight on the compacted floor tiles; the moving direction of the construction device can be adjusted by controlling the fifth drive member, and the moving speed and forward and backward movement of the construction device can be adjusted by controlling the sixth drive member, thereby meeting the different movement requirements of the construction device and further facilitating the construction personnel to control the movement of the construction device.

[0029] In summary, this application has at least one of the following beneficial effects:

[0030] 1. While improving the efficiency of floor tile compaction, it also facilitates construction workers to more accurately control the force of the construction device in compacting the floor tiles, thereby further improving the compaction effect of the floor tiles and improving the stability and reliability of the construction device in the process of compacting the floor tiles;

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] Reference Figure 1 The present invention discloses an intelligent municipal road construction device, comprising a vehicle body 1, a compacting mechanism 2, and a moving mechanism 3. The moving mechanism 3 is used to move the vehicle body 1, the compacting mechanism 2, and other components. The compacting mechanism 2 compacts the floor tiles below the vehicle body 1 by applying a vertical downward force. When the construction device is in operation, the moving mechanism 3 moves the construction device while the compacting mechanism 2 compacts the floor tiles.

[0041] Reference Figure 1 and Figure 2 The tamping mechanism 2 includes a tamping plate 21, a plurality of power rods 22, a driving assembly 23, a buffer assembly 24, and a regulating assembly 25. The driving assembly 23 is used to drive the power rod 22 to move back and forth in the vertical direction; the movement of the power rod 22 drives the tamping plate 21 to move, and the tamping plate 21 is used to resist the floor tiles and apply force to the floor tiles to perform tamping operations; the buffer assembly 24 is used to reduce the impact of the reaction force applied by the tamping plate 21 on the floor tiles and transmitted to other structures of the tamping mechanism 2 through the power rod 22; the regulating assembly 25 is used for construction personnel to adjust the force of the tamping plate 21 on the floor tiles according to the requirements of the tamping operation, so that the tamping mechanism 2 can meet more usage requirements. In order to facilitate the display of the specific structure of the tamping mechanism 2, it is preferred that the tamping mechanism 2 includes a total of one power rod 22. If the structural stability is considered, the number of power rods 22 can also be more.

[0042] The vehicle body 1 is preferably a rectangular parallelepiped structure, and the moving mechanism 3 lifts the vehicle body 1 so that the vehicle body 1 maintains a distance from the floor tiles during movement. A plurality of buttons 4 are installed on the surface of the vehicle body 1, and construction workers can control the operation of the compacting mechanism 2 and the moving mechanism 3 by corresponding buttons 4.

[0043] The tamping plate 21 is preferably a rectangular plate structure, and is positioned horizontally between the vehicle body 1 and the floor tiles. The power rod 22 is preferably a cylindrical structure as a whole, and is installed on the vehicle body 1 with its axis vertical. The lower end of the power rod 22 extends through the vehicle body 1 and is positioned above the tamping plate 21. The upper end of the power rod 22 is positioned inside the vehicle body 1, and the power rod 22 is vertically connected to the vehicle body 1.

[0044] The sliding process of the power rod 22 relative to the vehicle body 1 is limited. During the upward movement of the power rod 22, the tamping plate 21 will be driven to move upward. When the power rod 22 moves upward to the extreme position, the tamping plate 21 is located close to the vehicle body 1 and there is still a distance between the tamping plate 21 and the vehicle body 1; during the downward movement of the power rod 22, the tamping plate 21 will be driven to move downward. When the power rod 22 moves downward to the extreme position, the tamping plate 21 is against the floor tiles and exerts a force on the floor tiles in the vertical downward direction.

[0045] Reference Figure 2 The drive assembly 23 includes a first drive member 231, a plurality of drive wheels 232, and a plurality of reset members 233. Each of the plurality of drive wheels 232 and the plurality of reset members 233 corresponds one-to-one with the plurality of power rods 22. Accordingly, the drive assembly 23 preferably includes a total of one drive wheel 232 and one reset member 233. The first drive member 231 is located inside the vehicle body 1. The first drive member 231 is preferably a servo motor. The output shaft of the first drive member 231 extends outward in a horizontal direction. The length direction of the output shaft of the first drive member 231 is preferably parallel to the length direction of the vehicle body 1.

[0046] The drive wheel 232 is mounted on the output shaft of the first drive member 231. The first drive member 231 drives the drive wheel 232 to rotate about the axis of its output shaft. The drive wheel 232 is located above the power rod 22. During the rotation of the drive wheel 232, the drive wheel 232 applies a force to the upper end of the power rod 22, driving the power rod 22 downward.

[0047] The power rod 22 has a limiting portion 221 extending outwardly from the circumference thereof. The limiting portion 221 is an annular structure as a whole. The limiting portion 221 is located inside the vehicle body 1, and during the sliding of the power rod 22 relative to the vehicle body 1, the limiting portion 221 remains inside the vehicle body 1. The reset member 233 is located below the limiting portion 221, and the reset member 233 drives the power rod 22 to move upward to the extreme position and maintain it. Preferably, the reset member 233 is a compression spring, which is sleeved on the power rod 22, and the two ends of the reset member 233 are fixedly connected to the limiting portion 221 and the vehicle body 1, respectively. During the rotation of the driving wheel 232, the reset member 233 drives the upper end of the power rod 22 to maintain contact with the driving wheel 232, so that the power rod 22 can move in the vertical direction as the driving wheel 232 rotates.

[0048] Reference Figure 3 The buffer assembly 24 includes an elastic member 241. The lower end of the power rod 22 is slidably connected to the tamping plate 21. The direction in which the power rod 22 and the tamping plate 21 slide relative to each other is the same as the direction in which the power rod 22 slides relative to the vehicle body 1. Preferably, the position where the power rod 22 and the tamping plate 21 slide relative to each other is located at the center of the tamping plate 21. The relative sliding of the power rod 22 and the tamping plate 21 is limited. When the power rod 22 and the tamping plate 21 slide away from each other to the extreme position, there is space between the power rod 22 and the tamping plate 21 for the installation of the elastic member 241. Preferably, the elastic member 241 is made of rubber material. Under normal circumstances, the elastic member 241 remains in its original shape and will drive the power rod 22 and the tamping plate 21 to slide away from each other to the extreme position and maintain it. When the tamping plate 21 is against the floor tiles and the power rod 22 applies a force to the tamping plate 21, the elastic member 241 will be squeezed and deformed, thereby having a buffering effect.

[0049] In one embodiment, the buffer assembly 24 further includes a buffer pad 242, which is fixedly mounted on the end surface of the tamping plate 21 facing away from the vehicle body 1. Preferably, the buffer pad 242 is a rectangular plate-shaped structure and is also made of rubber. The buffer pad 242 replaces the tamping plate 21 in contact with the floor tiles, thereby effectively preventing hard contact between the tamping plate 21 and the floor tiles, and reducing the probability of damage or even cracking of the floor tiles after tamping.

[0050] Reference Figure 2 and Figure 3 In one embodiment, the drive wheel 232 is preferably cam-shaped and fixedly connected to the output shaft of the first drive member 231. The control assembly 25 includes a second drive member 251. The end of the first drive member 231 away from its own output shaft is slidably connected to the vehicle body 1. The sliding direction of the first drive member 231 is preferably parallel to the width direction of the vehicle body 1. The second drive member 251 is located inside the vehicle body 1 and is fixedly connected to the second drive member 251. The second drive member 251 is preferably a cylinder. The end of the piston rod of the second drive member 251 is fixedly connected to the first drive member 231. The second drive member 251 drives the first drive member 231 to slide relative to the vehicle body 1.

[0051] The sliding process of the first driving member 231 relative to the vehicle body 1 is limited. When the first driving member 231 slides to the extreme position in the direction close to the power rod 22, the output shaft of the first driving member 231 is located directly above the power rod 22, and the rotation axis of the driving wheel 232 intersects with the axis of the power rod 22. At this time, the driving wheel 232 rotates to drive the power rod 22 to move the maximum stroke, that is, the tamping force of the tamping plate 21 on the floor tiles is the maximum; when the first driving member 231 slides to the extreme position in the direction away from the power rod 22, the output shaft of the first driving member 231 is located on one side of the power rod 22, and the rotation axis of the driving wheel 232 is perpendicular to and does not intersect with the axis of the power rod 22. At this time, the driving wheel 232 rotates to drive the power rod 22 to move the minimum stroke, that is, the tamping force of the tamping plate 21 on the floor tiles is the minimum.

[0052] Reference Figure 4 In one embodiment, the drive wheel 232 preferably has a truncated cone structure with a cross-sectional profile identical to that of the cam. The drive wheel 232 is slidably connected to the output shaft of the first drive member 231, and the sliding direction of the drive wheel 232 is parallel to its own rotational axis. The control assembly 25 includes a third drive member 252, which is fixedly mounted on the output shaft of the first drive member 231. The third drive member 252 is preferably a servo motor, and the third drive member 252 controls the sliding of the drive wheel 232 via a screw drive.

[0053] The cross-sectional size of the driving wheel 232 gradually increases or decreases along the direction of its own rotation axis, and the third driving member 252 is limited in the process of driving the driving wheel 232 to slide in the direction close to the first driving member 231. Preferably, when the third driving member 252 drives the driving wheel 232 to slide to the extreme position, the position with the largest cross-sectional size on the driving wheel 232 is against the upper end of the power rod 22. At this time, the driving wheel 232 rotates to drive the power rod 22 to move the maximum stroke, that is, the tamping force of the tamping plate 21 on the floor tiles is the largest; when the third driving member 252 drives the driving wheel 232 to slide in the direction away from the first driving member 231 to the extreme position, the position with the smallest cross-sectional size on the driving wheel 232 is against the upper end of the power rod 22. At this time, the driving wheel 232 rotates to drive the power rod 22 to move the minimum stroke, that is, the tamping force of the tamping plate 21 on the floor tiles is the smallest.

[0054] Back to Figure 2 and Figure 3 In one embodiment, the compacting mechanism 2 further includes a plurality of abutment plates 26, each corresponding to each of the power rods 22. Accordingly, the compacting mechanism 2 preferably includes a single abutment plate 26. The abutment plate 26 is preferably a plate-shaped structure, and is fixedly mounted on the upper end of the power rod 22 in a vertical position in a detachable manner. The length direction of the abutment plate 26 is parallel to the width direction of the vehicle body 1. The abutment plate 26 is preferably detachably connected to the power rod 22 via a screw.

[0055] The abutment plate 26 replaces the upper end of the power rod 22 to contact the driving wheel 232. The end surface of the abutment plate 26 facing away from the power rod 22 is the abutment surface 261. During the rotation of the driving wheel 232, the abutment surface 261 is kept in contact with the abutment surface 261. The abutment surface 261 is an arc-shaped surface. The position on the arc-shaped surface that intersects with the axis of the power rod 22 is the top of the arc, and the two ends of the arc-shaped surface in the length direction are the bottom of the arc. The slope of the arc trajectory of the arc surface gradually decreases from the bottom of the arc to the top of the arc, so that when the driving wheel 232 drives the power rod 22 to move downward through the abutment surface 261, the power rod 22 gradually increases the force applied to the tamping plate 21, and the speed of the power rod 22 moving downward can gradually decrease, thereby reducing the probability of the tamping mechanism 2 and the floor tiles being damaged due to excessive force during the tamping operation.

[0056] Back to Figure 3 In one embodiment, the tamping mechanism 2 further includes a pressure sensor 27, which is fixedly mounted on one end surface of the tamping plate 21 near the power rod 22. The pressure sensor 27 is located between the elastic member 241 and the tamping plate 21, with the upper end of the pressure sensor 27 abutting against the lower end of the elastic member 241. When the power rod 22 moves downward to compress the elastic member 241 and apply a force to the tamping plate 21, the pressure sensor 27 can detect the magnitude of the applied force. Since the pressure sensor 27 is a common prior art, it will not be described in detail here.

[0057] Reference Figure 1 A display screen 5 is also fixedly mounted on the surface of the vehicle body 1. The relevant operating parameters of the compacting mechanism 2 and the moving mechanism 3 are digitally displayed on the display screen 5, including the pressure sensor 27. Construction workers can use the data detected by the pressure sensor 27 on the display screen 5 to determine the compacting force of the compacting mechanism 2 on the floor tiles, thereby judging the compacting effect of the compacting mechanism 2 on the floor tiles.

[0058] Reference Figure 2 and Figure 4In one embodiment, the tamping mechanism 2 further includes a limiting assembly 28, which is fixedly mounted inside the vehicle body 1. The limiting assembly 28 is located below the limiting portion 221 on the power rod 22, and is located on one side of the reset member 233. The limiting assembly 28 includes a fourth driving member 281 and a limiting member 282. The bottom of the fourth driving member 281 is fixedly connected to the bottom of the interior space of the vehicle body 1. Preferably, the fourth driving member 281 is a cylinder, and the piston rod of the fourth driving member 281 moves in the vertical direction. The limiting member 282 is fixedly mounted on the end of the piston rod. There is a gap between the limiting member 282 and the reset member 233 in the horizontal direction, and the projection of the limiting member 282 on the floor tile in the vertical direction overlaps with the projection of the limiting portion 221 on the power rod 22 on the floor tile in the vertical direction. That is, during the movement of the power rod 22, the limiting portion 221 can abut against the limiting member 282.

[0059] The fourth driving member 281 has a limit in the process of driving the limiting member 282 to move in the vertical direction. When the fourth driving member 281 drives the limiting member 282 to move in the direction away from the driving assembly 23 to the limit position, if the driving assembly 23 drives the power rod 22 to move with the maximum stroke and the power rod 22 moves downward to the limit position, at this time, there is a vertical distance between the limiting member 282 and the limiting portion 221 on the power rod 22; when the fourth driving member 281 drives the limiting member 282 to move in the direction close to the driving assembly 23 to the limit position, if the driving assembly 23 drives the power rod 22 to move with the minimum stroke and the power rod 22 moves downward to the limit position, at this time, the limiting portion 221 on the power rod 22 just contacts and abuts against the limiting member 282. In the process of the driving assembly 23 causing the power rod 22 to reciprocate, each time the power rod 22 moves downward to the limit position, the limiting portion 221 on the power rod 22 can contact and abut against the limiting member 282.

[0060] There are signal connections among the driving component 23 , the limiting component 28 and the regulating component 25 .

[0061] When the compacting mechanism 2 is in standby mode, the drive assembly 23 also remains in standby mode and cooperates with the reset member 233 to maintain the power rod 22 at its maximum upward position, thereby maintaining the spacing between the compacting plate 21 and the floor tiles. At this time, the reset member 233 applies a vertical upward force to the power rod 22, that is, the reset member 233 supports both the power rod 22 and the compacting plate 21. This long-term operation will weaken the elastic reset ability of the reset member 233.

[0062] Therefore, when the driving assembly 23 is on standby, the limiting assembly 28 will replace the reset member 233 to support the power rod 22 and the tamping plate 21, and the fourth driving member 281 drives the limiting member 282 to move upward until it contacts and maintains the limiting portion 221 on the power rod 22.

[0063] When the driving assembly 23 is in operation, if the limiting assembly 28 is controlled to cause the fourth driving member 281 to drive the limiting member 282 toward the driving wheel 232, the limiting member 282 will abut against the limiting portion 221 on the power rod 22, and the driving wheel 232 will no longer be able to rotate at its current position. At this time, the driving assembly 23 will be in a standby state by driving the power rod 22 downward to the limit position, and the regulating assembly 25 will be operated to move the driving wheel 232 away from the power rod 22 until the rotation of the driving wheel 232 is no longer restricted by the power rod 22. The driving assembly 23 will then resume operation and the regulating assembly 25 will resume standby. If the limiting assembly 28 is controlled to cause the fourth driving member 281 to drive the limiting member 282 toward the direction away from the driving wheel 232, the driving wheel 232 will no longer be able to drive the power rod 22 to rotate at its current position until the limiting member 282 abuts against the limiting portion 221 on the power rod 22. At this time, the driving component 23 will wait in a state of driving the power rod 22 to move downward to the extreme position, and the regulating component 25 will work to move the driving wheel 232 toward the direction close to the power rod 22 until the driving wheel 232 drives the power rod 22 to move downward until the limit member 282 contacts and abuts against the limit portion 221 on the power rod 22.

[0064] There is also a signal connection between the pressure sensor 27 and the limit assembly 28.

[0065] The construction personnel can preset the value of the pressure sensor 27 on the display screen 5, and the limit component 28 will work according to the value preset by the construction personnel, and the fourth driving member 281 will drive the limit component 282 to move to the appropriate position; then, the driving component 23 will be on standby due to the change in the position of the limit component 282, and the regulating component 25 will work due to the standby of the driving component 23, so that the driving wheel 232 moves, so that the driving wheel 232 drives the power rod 22 to move downward to the extreme position, so that it can just contact and offset the limit component 282 after the position change. At this time, the magnitude of the force applied by the power rod 22 to the tamping plate 21 detected by the pressure sensor 27 is equal to the value preset by the construction personnel.

[0066] Back to Figure 2 In one embodiment, the construction device further includes a power supply mechanism 6 for providing energy to the compacting mechanism 2 and the moving mechanism 3. Preferably, the power supply mechanism 6 is a battery. The power supply mechanism 6 is fixedly mounted within the vehicle body 1, and preferably, the power supply mechanism 6 and the compacting mechanism 2 are located at opposite ends of the vehicle body 1 in the longitudinal direction. Since batteries are common in the art, they will not be described in detail here.

[0067] Back to Figure 1 and Figure 2In one embodiment, the moving mechanism 3 includes a track assembly 31, a fifth drive member 32, and a sixth drive member 33. The track assembly 31 is installed below the vehicle body 1 and is located below the power supply mechanism 6; the fifth drive member 32 is fixedly installed inside the vehicle body 1 and close to the power supply mechanism 6. The track assembly 31 is rotatably connected to the vehicle body 1, and the rotation axis of the track assembly 31 is vertical. Preferably, the fifth drive member 32 is a servo motor, and the output shaft of the fifth drive member 32 passes through the vehicle body 1 and is fixedly connected to the track assembly 31; the sixth drive member 33 is fixedly installed on the track assembly 31, and preferably the sixth drive member 33 is also a servo motor. The sixth drive member 33 provides power to the track assembly 31, driving the track movement to drive the construction device as a whole to move above the floor tiles. Since the use of tracks for movement is a common existing technology, the track assembly 31 will not be described in detail here.

[0068] During the process of the construction device compacting the floor tiles, the moving mechanism 3 drives the construction device as a whole to move toward the location of the floor tiles to be compacted on the compacted floor tiles. At the same time, the compacting mechanism 2 is located on the side of the moving mechanism 3 close to the floor tiles to be compacted. During the movement of the construction device as a whole, the compacting mechanism 2 compacts the floor tiles to be compacted.

[0069] In one embodiment, the construction device further includes a driver's seat 7 for a construction worker. Driver's seat 7 is fixedly mounted on the top of vehicle body 1. Driver's seat 7 is positioned on vehicle body 1 between compacting mechanism 2 and moving mechanism 3, and closer to compacting mechanism 2. When a construction worker is seated in driver's seat 7, the center of gravity of the entire construction device is centered along the length of vehicle body 1.

[0070] In order to facilitate construction workers to control the compacting mechanism 2 and the moving mechanism 3 on the driver's seat 7 , the display screen 5 and the plurality of buttons 4 on the surface of the vehicle body 1 are preferably located around the driver's seat 7 .

[0071] Both sides of the vehicle body 1 are provided with a step structure for construction workers to enter and exit the driver's seat 7. Since this is a common prior art, it will not be described in detail here.

[0072] The implementation principle of an intelligent municipal road construction device in the embodiment of the present application is as follows:

[0073] After the construction worker takes his place in the driver's seat 7, he controls the moving mechanism 3 and the compacting mechanism 2 through the multiple buttons 4 and the display screen 5. The moving mechanism 3 drives the entire construction device to move on the municipal road, and the compacting mechanism 2 compacts the floor tiles during the movement of the entire construction device.

[0074] When it is necessary to adjust the compacting force of the compacting mechanism 2 on the floor tiles, it is only necessary to preset the required value on the display screen 5. The limit assembly 28 will limit the position of the power rod 22 when it moves downward to the extreme position according to the preset value, thereby limiting the force applied by the power rod 22 to the compacting plate 21, so that the force applied by the power rod 22 to the compacting plate 21 and the value detected by the pressure sensor 27 are equal to the preset value; then, the driving assembly 23 will stand by to stop the driving wheel 232 from rotating, and at the same time, the regulating assembly 25 will work to control the movement of the driving wheel 232 until the driving wheel 232 rotates at its current position to drive the power rod 22 to move downward to the extreme position, and the limit member 282 can contact and resist the limit portion 221 on the power rod 22; thereafter, the driving assembly 23 will work again and the regulating assembly 25 will stand by. At this time, the compacting mechanism 2 will continue to compact the floor tiles with the same force as the preset value.

[0075] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
