Description

Technical Field

[0001] The present invention relates to municipal construction equipment, and particularly to a flipping brick-laying mechanism with positioning, scraping and rolling functions. Background Art

[0002] With the development of the current urban construction level, the requirements for municipal road surfaces are getting higher and higher. Large areas of flat floor tiles usually need to be laid in places such as sidewalks and squares. At present, the laying of floor tiles generally adopts pure manual operation or a combination of machinery and manual labor. The construction method of the combination of machinery and manual labor is as follows: the bricks are lifted by a rope through a crane, then the landing position is manually controlled and the bricks are unloaded, and finally the compaction operation is carried out. This laying method is time-consuming and laborious. The laying effect depends on the technical level of the construction workers. At the same time, the labor intensity of the workers is high, and more construction workers are required, which increases the laying cost.

[0003] At present, some brick-laying machines have emerged. However, for brick-laying, especially for flat road surface bricks, since they all need to go through the processes of ground scraping, brick-laying and compaction, the current brick-laying machines cannot fully realize the above three functions. Generally, they are only used for laying, and ground scraping and compaction need to rely on other equipment or manual operation, which is very inconvenient. Summary of the Invention

[0004] The present invention aims to provide a flipping brick-laying mechanism with positioning, scraping and rolling functions. The flipping brick-laying mechanism is installed on the mechanical boom at the front end of the brick-laying machine. Let the length of the brick-laying machine be the X direction and the width be the Y direction. The flipping brick-laying mechanism is provided with a laying main frame connected to the mechanical boom.

[0005] A flipping mechanism is installed on the laying main frame. Side frames are installed on both sides of the flipping mechanism. The side frames are slidably matched with the laying main frame so that the side frames and the flipping mechanism slide back and forth synchronously in the X direction. The flipping mechanism is provided with a Y-direction flipping shaft, and the flipping mechanism rotates on the side frames with the flipping shaft as the axis. Among them, a placing mechanism, a scraping mechanism and a rolling mechanism that rotate synchronously with the flipping shaft are fixedly installed on the flipping mechanism.

[0006] The placing mechanism is provided with a pallet and a bracket. The bricks are clamped between the pallet and the bracket. The rotation of the flipping shaft causes the placing mechanism with the bricks clamped at the rear side of the flipping mechanism to flip to the front side, and the clamped floor tiles are laid on the ground.

[0007] The scraping mechanism is provided with a Y-direction scraper. The rotation of the flipping shaft causes the scraper to be in inclined contact with the ground. The side frames and the flipping mechanism move back and forth on the laying main frame, and the ground is scraped flat by the scraper.

[0008] The rolling mechanism is provided with rolling wheels. The rotation of the turning shaft causes the rolling wheels to contact the upper surface of the laid floor tiles. The side frame and the turning mechanism move back and forth on the laying main frame, and the rolling wheels perform rolling operations on the laid floor tiles.

[0009] Two sets of positioning mechanisms are respectively installed on the laying main frame and the turning mechanism. The two sets of positioning mechanisms cooperate to provide positioning for floor tile laying.

[0010] Furthermore, front slide rail support plates and rear slide rail support plates are provided on both sides of the laying main frame. The rear slide rail support plate and the front slide rail support plate on the same side are fixedly connected by a quick-release connecting plate. The turning and tile-laying mechanism is detachably installed on the mechanical boom through this quick-release connecting plate.

[0011] Horizontal telescopic cylinders for driving the side frame and the turning mechanism to move back and forth in the X direction are installed on both sides of the laying main frame. The cylinder seat and the ejector rod of the horizontal telescopic cylinder are respectively connected to the rear slide rail support plate and the side frame.

[0012] Furthermore, support universal wheels are provided on the front side of the front slide rail support plate, and support feet are provided on the rear side of the front slide rail support plate.

[0013] Furthermore, the turning shaft is a turning oil cylinder, and the turning oil cylinder is installed on the side frame through a turning oil cylinder support plate.

[0014] Furthermore, the scraper is a serrated scraper, and the outer diameter of the rolling wheel is provided with axial ribs.

[0015] Furthermore, first laser emitters are installed at the front ends of the front slide rail support plates on both sides, and second laser emitters are installed at the front ends of the side frames on both sides.

[0016] Each first laser emitter is used to emit a "cross"-shaped first positioning laser to the ground directly below the other first laser emitter. The second laser emitter is used to emit a "cross"-shaped second positioning laser perpendicular to the ground. The laying position of the floor tiles is determined by the coincidence of the second positioning laser and the first positioning laser.

[0017] The angle between the first positioning laser emitted by the two first laser emitters and the ground is adjustable to adjust the distance between the two beams of first positioning laser.

[0018] Furthermore, the placing mechanism is provided with a clamping and fixing frame. The pallet is arranged on one side of the clamping and fixing frame. The clamping and fixing frame is provided with an adjustment guide rail in the Y direction. The bracket is arranged on the adjustment guide rail, and the bracket is connected to the clamping and fixing frame through a fine-tuning cylinder to adjust the position of the bracket in the Y direction.

[0019] A number of X-direction support plates are installed on the rear slide rail support plate, and rollers are arranged on the support plates.

[0020] The advantages of the present invention are as follows:

[0021] 1) The flipping mechanism is provided with a placing mechanism, a leveling mechanism, and a rolling mechanism that can rotate around the flipping axis. By means of the rotation of the flipping mechanism, ground leveling, floor tile placement, and floor tile rolling can be achieved. The structure is more compact and the functions are more complete;

[0022] 2) Two groups of laser positioning mechanisms are installed at the front end of the flipping and paving mechanism. One group is fixedly installed on the main laying frame, and the other group is installed on the side frame that can slide back and forth on the main laying frame. Each group of laser positioning mechanisms can emit cross-shaped positioning lasers for quickly positioning the laying position, so that the laid bricks are more neatly arranged.

[0049] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.

[0050] To thoroughly understand the present invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may have other embodiments.

[0051] Referring to Figure 1 as shown, the present invention provides a floor tile laying device 10, such as Figure 1 as shown, a traveling device 12 is installed on the chassis of the vehicle frame 11 of the floor tile laying device. The traveling device 12 is provided with 4 steerable traveling wheels 13, and the traveling device 12 can drive the floor tile laying device 10 to travel. For the convenience of the following description, we set the length direction of the vehicle frame 11 as the X direction and the width direction as the Y direction.

[0052] A lifting mechanism 100 and a clamping and pushing mechanism 200 are installed at the tail of the vehicle frame 11. A multi-axis mechanical boom 500 is installed at the front of the vehicle frame 11. A tilting brick laying mechanism 400 is installed on the mechanical boom 500, and a conveying mechanism 300 located between the tilting brick laying mechanism 400 and the clamping and pushing mechanism 200 is installed on the vehicle frame 11;

[0053] The lifting mechanism 100 is provided with a first transmission mechanism 104, a lifting plate 103, and a lifting device 120. The first transmission mechanism 104 transfers the floor tiles stacked up and down to the lifting plate 103, and the lifting device 120 drives the lifting plate 103 to lift upward;

[0054] The clamping and pushing mechanism 200 includes a forward movement guide rail 210 and a clamping device 220 slidably installed on the forward movement guide rail 210. The clamping device 220 clamps the two ends of the length of the floor tile after it is lifted to the top, conveys it forward in the X direction, then releases it and lies flat on the conveying mechanism 300. The conveying mechanism 300 conveys the floor tile forward in the X direction to the tilting brick laying mechanism 400;

[0055] The tilting brick laying mechanism 400 is provided with a laying main frame. A tilting mechanism 430 that slides back and forth in the X direction is installed on the laying main frame. The tilting mechanism 430 is provided with a Y-direction tilting shaft. The tilting mechanism 430 is provided with a placing mechanism 431 that rotates around the tilting shaft. After the placing mechanism 431 clamps a floor tile conveyed by the conveying mechanism 300, the placing mechanism 431 tilts forward to lay the clamped floor tile on the ground;

[0056] Positioning mechanisms are respectively installed on the laying main frame and the flipping mechanism 430, and the two sets of positioning mechanisms cooperate to provide positioning for floor tile laying.

[0057] For the floor tile laying device 10 provided by the present invention, the stacked floor tiles are integrally lifted by the lifting mechanism 100, and then the clamping and pushing mechanism 200 clamps and transfers the floor tiles one by one and places them flat on the conveying mechanism 300. The conveying mechanism 300 transports the floor tiles placed flat to the flipping and tiling mechanism 400, and the flipping and tiling mechanism 400 lays the floor tiles flat on the ground. The whole process is fully mechanized, greatly improving the laying efficiency and reducing the required labor cost at the same time. At the same time, when laying floor tiles, this device does not require manual assistance, and the operator does not need to participate in heavy work, reducing the labor intensity of people.

[0058] The structure of the lifting mechanism 100 will be further described below:

[0059] The lifting mechanism 100 is provided with a longitudinal lifting bracket 102 installed at the tail of the vehicle frame 11. The first transmission mechanism 104 is fixedly installed at the bottom of the longitudinal lifting bracket 102. The lifting plate 103 is driven by a lifting device 120 on the longitudinal lifting bracket 102 to move up and down in the vertical direction of the first transmission mechanism 104. The lifting plate 103 is provided with an opening groove corresponding to the position of the first transmission mechanism 104 so that the lifting plate 103 can be lowered below the upper surface of the first transmission mechanism 104. A storage bracket 130 is installed at the bottom of the rear side of the lifting bracket. The front end of the storage bracket 130 is rotatably connected to the bottom of the rear side of the longitudinal lifting bracket 102. The storage bracket 130 can be turned up and down with the front end as the rotation point and folded for storage, as Figure 3b and 3c shown. A second transmission mechanism 132 is provided on the storage bracket 130. The storage bracket 130 conveys the floor tiles stacked up and down forward in the X direction to the first transmission mechanism 104, and the first transmission mechanism 104 continues to convey the floor tiles forward to the lifting plate 103. A guard plate 101 is provided on the upper part of the longitudinal lifting bracket 102.

[0060] In an alternative embodiment, lifting devices 120 are mounted on the longitudinal lifting bracket 102 and are located on both sides of the lifting plate 103 in the Y direction. Each lifting device 120 includes a lifting cylinder 121 and a lifting chain 122. The lifting cylinder 121 is vertically fixed on the longitudinal lifting bracket 102; both ends of the lifting chain 122 are fixedly connected to the lifting plate 103 and the top rod of the lifting cylinder 121 respectively, or both ends of the lifting chain 122 are located on both sides of the lifting cylinder 121 and straddle the top rod of the lifting cylinder 121. One end of the lifting chain 122 is fixedly connected to the lifting plate 103, and the other end is fixed on the longitudinal lifting bracket 102 on one side of the lifting cylinder 121. The upward sliding of the top rod of the lifting cylinder 121 drives the end of the lifting chain 122 to move upward, and the two groups of lifting chains 122 drive the middle lifting plate 103 to be steadily lifted.

[0061] In an alternative embodiment, vertical guide channel steel rails 105 are provided on the longitudinal lifting bracket 102 and are located on both sides of the lifting plate 103. Lifting webs 106 are slidably mounted up and down on each vertical guide channel steel rail 105. One end of the lifting chain 122 and the lifting plate 103 are both fixedly connected to the lifting web 106.

[0062] In an alternative embodiment, the storage bracket 130 is mounted on the bottom of the longitudinal lifting bracket 102 through a self-resetting flipping bracket 131, and a spring support 135 is mounted at the bottom of the longitudinal lifting bracket 102;

[0063] A limit steel pipe 138 and a reset spring 137 are mounted at the bottom of the self-resetting flipping bracket 131,

[0064] The limit steel pipe 138 sequentially passes through two baffles 136 on the back of the self-resetting flipping bracket 131 and is rotatably connected to the spring support 135. The reset spring 137 is sleeved on the limit steel pipe 138 between the two baffles 136;

[0065] The transverse width of the storage bracket 130 is smaller than the transverse width of the longitudinal lifting bracket 102, and the storage bracket 130 is rotatably connected to the center of the bottom of the longitudinal lifting bracket 102.

[0066] The lifting mechanism 100 adopts the forklift lifting principle. The lifting cylinder 121 and the lifting chain 122 are combined and placed on the left and right sides. One end of the chain is connected to the vehicle frame, and the other end is connected to the brick lifting plate 103. Bearings are installed on both sides of the lifting plate 103 and can roll up and down on the vertical guide channel steel rails 105. A second transmission mechanism 132 is provided on the storage bracket 130. The second transmission mechanism 132 is composed of rollers, a sprocket chain 133, a drive motor 134, etc., to realize the reception and transmission of bricks.

[0067] Combined with Figures 3a - 3dAs shown in the figure, the design highlights of the lifting mechanism 100 are as follows: 1) The design of the storage and lifting parts can ensure the continuous supply of bricks, meet the front-end brick demand, improve efficiency, and the structure is compact. 2) The lifting part design can accurately lift the corresponding height according to the thickness of the bricks. 3) When the forklift places materials in the design, the clamping opening formed by the two end plates of the forklift corresponds to the storage vertical plate, and the width of the storage vertical plate is much smaller than the width of the clamping opening, which can be applicable to various types of forklifts, facilitating the placement and transportation of large and small bricks, and the operation is very convenient. 4) When the storage materials complete the operation, the storage vertical plate can be pushed manually and rotated upward by 90° to retract the storage part to the vertical state, reducing the overall vehicle length and facilitating transfer and transportation. And when the storage mechanism is placed flat, its storage outer frame and the vehicle frame can be self-limited to support its flat state, and the spring assembly is used to easily place and retract the storage structure.

[0068] The following will refer to Figures 4a - 4f As shown in the figure, the structure of the clamping and pushing mechanism 200 will be further described:

[0069] The forward moving guide rail 210 is provided with two first slide rails 211 in the X direction. An upper track 212 is provided on the relative inner side surfaces of the first slide rails 211. A lower lifting track 213 is provided on the first slide rails 211 below the upper track 212. The lower side of the lower lifting track 213 is provided with two front and rear inlets 213-1 opening downward. A pair of front and rear first rollers 202 are installed in each upper track 212. The front and rear ends on both sides of the clamping device 220 are respectively fixed with second rollers 221. The corresponding first rollers 202 and second rollers 221 are movably connected by a connecting rod 230. The first transverse movement propulsion cylinder 240 drives the first rollers 202 to slide forward in the upper track 212 to drive the clamping device 220 to move forward transversely. During the forward sliding process of the first rollers 202, the second rollers 221 are driven by the connecting rod 230 to enter the lower lifting track 213 through the inlet 213-1 to lift the height of the clamping device 220.

[0070] In an optional embodiment, a pair of front and rear first rollers 202 in the upper track 212 are both installed on a side push plate 214. The side push plate 214 is fixedly connected to the ejector rod of the first transverse movement propulsion cylinder 240. The first transverse movement propulsion cylinder 240 pushes the side push plate 214 to drive a pair of front and rear first rollers 202 to roll back and forth in the upper track 212.

[0071] The upper and lower ends of the connecting rod 230 are respectively hinged to the first rollers 202 in the upper first slide rail 211 and the second rollers 221 of the clamping device, with a total of four hinge points, thus forming a parallelogram four-bar mechanism (as Figure 4d(in the rectangular dotted line frame), that is, the four corners of the clamping device are respectively movably connected below the first slide rail 211 through the connecting rods 230; the second rollers 221 are rotatably installed on the frame of the clamping device 220. During specific operation, the first transverse translation propulsion cylinder 240 drives the side push plate 214 to drive the first roller 202 to roll forward in the upper rail 212, and the lower end of the connecting rod 230 drives the clamping device 220 to form a parallelogram linkage mechanism to realize the forward push of the entire clamping mechanism. Before the clamping device 220 slides forward, the second rollers 221 provided on the clamping device 220 first enter the lower lifting rail 213 to lift the height of the clamping device 220. Therefore, the height of the bricks clamped by it will also increase, avoiding friction between the clamped brick body and the brick body below it and scratching the surface of the brick body, as Figure 4e shown. The clamping device 220 first lifts a little height and then moves forward. Preferably, when the clamping device 220 is at the position at the end of the stroke, both of the two second rollers 221 are exactly located at the entrance of the lower lifting rail 213, so that the clamping device 220 first lifts the height and then slides forward.

[0072] As Figure 4c shown, the clamping device 220 includes a clamping frame 223, and the clamping frame 223 is provided with a second slide rail 224 in the Y direction and a multi-link linkage mechanism. Two relatively slidable clamping plates 225 are provided on the second slide rail 224. The multi-link linkage mechanism is composed of a middle swing rod 226 and two clamping connecting rods 227 hinged at both ends of the swing rod 226. The center of the swing rod 226 is rotationally connected to the clamping frame 223 through a swing rod center pin. The other ends of the two clamping connecting rods 227 are respectively hinged to the opposite surfaces of the two clamping plates 225; one end of the swing rod 226 is hinged to the clamping driving cylinder 228, and the clamping driving cylinder 228 drives the multi-link linkage mechanism to drive the two clamping plates 225 to slide relatively or towards each other on the second slide rail 224 to clamp or release the floor tiles.

[0073] By adopting the above multi-link linkage mechanism, only one clamping driving cylinder 228 can realize the relative or opposite sliding of the two clamping plates 225 on the second slide rail 224 at the same time to clamp or release the floor tiles, simplifying the driving structure. On the other hand, the movements of the two clamping plates 225 are synchronized, making the clamping and releasing actions more linear. Preferably, rubber plates are detachably installed on the opposite surfaces of the two clamping plates 225 to protect the floor tiles when clamping the floor tiles.

[0074] In an alternative embodiment, the conveying mechanism 300 is a conveying mechanism based on rollers or belts.

[0075] Next, with reference to Figures 6a - 6f shown, the structure of the flipping and paving mechanism 400 will be further described below:

[0076] The main frame structure of the tilting brick-laying mechanism 400 is as follows: Rear slide rail support plates 401 are provided on both sides of the rear part of the tilting brick-laying mechanism 400, and front slide rail support plates 402 are provided on both sides of the front part. Support feet 404 and support universal wheels 405 are arranged at the bottom of the front slide rail support plates 402. The support feet 404 can, after the tilting brick-laying mechanism 400 is detached from the mechanical boom 500, together with the support universal wheels 405, keep the tilting brick-laying mechanism 400 parked and stable. When the placement bracket 431-5 is pulled out after placing floor tiles, the manipulator legs can hold against the laid bricks to prevent the positioned bricks from moving. The rear slide rail support plates 401 and the front slide rail support plates 402 are fixedly connected through quick-release connecting plates 403, and the tilting brick-laying mechanism 400 is detachably installed between the quick-release mounting brackets 531 on both sides through the quick-release connecting plates 403.

[0077] Side frames 436 that are slidably matched with the front slide rail support plates 402 are installed on both sides of the tilting mechanism 430, that is, the side frames 436 can drive the tilting mechanism 430 to slide back and forth, and the tilting mechanism 430 can rotate on the side frames 436. The rear slide rail support plates 401 are connected to the tilting mechanism 430 through horizontal telescopic cylinders 406, and the horizontal telescopic cylinders 406 drive the side frames 436 and their tilting mechanisms 430 to move back and forth in the X direction.

[0078] As Figures 6e - 6f shown, a leveling mechanism 432 and a rolling press mechanism 433 that rotate around the tilting shaft are further installed on the tilting mechanism 430. The leveling mechanism 432, the rolling press mechanism 433, and the placement mechanism 431 rotate synchronously around the tilting shaft, and the tilting shaft is the tilting oil cylinder 434. The structures and working principles of the leveling mechanism 432 and the rolling press mechanism 433 will be further described below:

[0079] The leveling mechanism 432 is provided with a serrated scraper. Through the tilting of the leveling mechanism 432, the scraper is in inclined contact with the ground, and the horizontal telescopic cylinder 406 drives the entire tilting mechanism 430 to move back and forth to level the ground. Among them, by adjusting or replacing scrapers with different widths, different-width bricks can be adapted. The leveling mechanism 432 first reaches a predetermined position through the positioning of the positioning mechanism, and through the tilting of the tilting oil cylinder 434, the starting position of the leveling mechanism 432 for leveling is realized, and then the horizontal telescopic cylinder 406 drives the tilting mechanism 430 to move horizontally back and forth in the X direction to achieve the purpose of leveling the ground.

[0080] The rolling press mechanism 433 is provided with a rolling press wheel with convex ribs on its outer diameter. Through the tilting of the rolling press mechanism 433, the rolling press wheel is in contact with the upper surface of the laid floor tiles, and the horizontal telescopic cylinder 406 drives the tilting mechanism 430 to move back and forth to perform a rolling press operation on the laid bricks. The outer diameter of the rolling press wheel has convex ribs, and the bricks are compacted through rolling and knocking.

[0081] As shown Figure 6d in the figure, a first laser emitter 421 is installed at the front end of the front slide rail support plates 402 on both sides, and a second laser emitter 422 is installed at the front end of the side frames 436 on both sides; each first laser emitter 421 is used to emit a cross-shaped first positioning laser 421-1 to the ground directly below the first laser emitter 421 on the other side, and the second laser emitter 422 is used to emit a cross-shaped second positioning laser 422-1 perpendicular to the ground for preliminary positioning. When the flipping mechanism 430 slides forward, it will drive the second laser emitter 422 to move forward, and the positioning of the floor tiles to be laid is determined by the coincidence of the second positioning laser 422-1 and the first positioning laser 421-1. Among them, the colors of the first positioning laser 421-1 and the second positioning laser 422-1 are different, which is convenient for us to determine whether the first positioning laser 421-1 and the second positioning laser 422-1 on the same side of the ground coincide.

[0082] Preferably, the angles of the two first laser emitters 421 on the front slide rail support plates 402 are adjustable, so as to change the included angle between the first positioning laser 421-1 and the ground, and adjust the distance between the two first positioning lasers 421-1 to adapt to the positioning of floor tiles of different widths.

[0083] The laser positioning mechanism controls the flipping brick-laying mechanism 400 to always maintain a horizontal condition through a mechanical moving arm, and longitudinally and horizontally positions the flipping brick-laying mechanism 400 based on the principle of laser positioning. The positioning principle is as follows:

[0084] Since two groups of laser positioning devices are provided on the left and right sides of the vehicle frame in the present invention, and they are arranged symmetrically left and right. One group is the first laser emitters 421 fixed on the front slide rail support plates 402 at the front ends of both sides of the main laying frame, which are fixedly connected to the mechanical moving arm. The function is to position the whole vehicle. When laying the next brick, the two groups of first laser emitters 421 on the whole vehicle emit cross-shaped first positioning lasers 421-1 to the ground on the opposite side, and use the laid bricks or markings as marks to roughly position the whole machine, ensuring that the position deviation is within the specified range, and preparing for the adjustment of the position of the front flipping brick-laying mechanism 400; the other group is the second laser emitters 422 fixed on the side frames 436 of the flipping mechanism 430, which move synchronously with the side frames 436. After the whole machine stops, before the leveling, brick-laying, and compaction links, the second laser emitters 422 emit two cross-shaped second positioning lasers 422-1 perpendicular to the ground. When the second positioning laser 422-1 on the same side basically coincides with the first positioning laser 421-!1, the placement position can be predicted, and only a small amount of position adjustment is required to complete the laying position positioning, so that the laid bricks are more neatly arranged.

[0085] As shown Figure 6fAs shown in the figure, the placing mechanism 431 is provided with a clamping and fixing frame 431-1. A support plate 431-4 is arranged on one side of the clamping and fixing frame 431-1. The clamping and fixing frame 431-1 is provided with an adjusting guide rail 431-2 in the Y direction. A bracket 431-5 on the same side as the support plate is arranged on the adjusting guide rail 431-2. The bracket 431-5 is connected to the clamping and fixing frame 431-1 through a fine-tuning cylinder 431-3 to adjust the position of the bracket 431-5 in the Y direction, so as to realize the lateral fine-tuning and positioning when the tilting brick-laying mechanism 400 places floor tiles.

[0086] A number of support plates 407 in the X direction are installed on the rear slide rail support plate 401. Rollers are arranged on the support plates 407. The support plates 407 play a role in transferring bricks in the middle. The conveying mechanism 300 conveys the floor tiles forward in the X direction and transfers them between the support plate 431-4 and the bracket 431-5 through the support plates 407.

[0087] The tilting brick-laying mechanism 400 of the present invention is an infrared laser positioning laying system integrating leveling, placing and compaction. When laying road bricks, under the guidance of the positioning mechanism, the tilting brick-laying mechanism 400 first levels the ground, then places the floor tiles, and then compacts the floor tiles. The leveling mechanism 432, the placing mechanism 431 and the roller pressing mechanism 433 are all connected to the tilting oil cylinder 434. The tilting oil cylinder 434 is installed on the side frame 436 through the tilting oil cylinder support plate 435. The tilting oil cylinder 434 enables the leveling mechanism 432, the placing mechanism 431 and the roller pressing mechanism 433 to tilt more than 180° along with the tilting oil cylinder 434.

[0088] The following refers to Figures 5a - 5b As shown in the figure, the structure of the mechanical boom 500 will be further described below:

[0089] A mechanical boom 500 is symmetrically installed on the left and right sides of the front part of the vehicle frame 11. The two mechanical booms 500 are fixedly connected through a connecting rod 540. A vertical guide rail 501 and a horizontal guide rail 503 are fixed on the left and right sides of the front part of the vehicle frame 11. A vertically sliding vertical slider support 502 is installed on the vertical guide rail 501. A horizontally sliding horizontal slider 504 is installed on the horizontal guide rail 503; the vertical slider support 502 is connected to a vertical lifting mechanism 505 fixed to the front part of the vehicle frame 11, and the horizontal slider 504 is connected to a horizontal pushing mechanism 506 fixed to the front part of the vehicle frame 11. The vertical lifting mechanism 505 and the horizontal pushing mechanism 506 are any one of a cylinder, a hydraulic cylinder, an electric push rod and a screw pair.

[0090] The mechanical boom 500 includes a longitudinal leg 530, a horizontal upper arm 510, and a horizontal lower arm 520. The front ends of the upper arm 510 and the lower arm 520 are both hinged to the leg 530. The rear end of the upper arm 510 is hinged to the vertical slider support 502. The lower arm 520 is fixedly connected to the horizontal slider 504, and the rear end of the lower arm 520 is movably connected to the upper arm 510 through a connecting rod support arm 521. As Figure 5b described, the upper arm 510, the lower arm 520, the leg 530, and the connecting rod support arm 521 form a parallelogram structure (as shown by the dotted line). The advantage of the parallelogram structure is that the front leg can be better controlled by the rear vertical lifting mechanism 505 and the horizontal pushing mechanism 506. A quick-release mounting bracket 531 is installed at the bottom of the leg 530. A swing cylinder 532 is connected between the quick-release mounting bracket 531 and the leg 530. A quick-release support universal wheel 533 is installed at the bottom of the quick-release mounting bracket 531.

[0091] As Figure 5c shown, the quick-release mounting bracket 531 is provided with two rotating shafts. The first rotating shaft is installed on the leg 530 through a pin shaft 531-2. The second rotating shaft 531-6 is hinged to the swing rod of the swing cylinder 532. The swing cylinder 532 drives the quick-release mounting bracket 531 to rotate around the pin shaft 531-2 as the axis.

[0092] The quick-release mounting bracket 531 is provided with two triangular plates 531-1 arranged in parallel. The three vertices of the two triangular plates 531-1 are fixedly connected by connecting columns. The first connecting column is coaxially arranged with the pin shaft 531-2. The other two second connecting columns 531-7 are used to connect with the reserved bayonets of the laying mechanism. The second rotating shaft 531-6 is arranged between two of the connecting columns; one of the second connecting columns is a smooth shaft 531-7, and the other second connecting column is a locking shaft 531-3 with a non-circular cross-section. One end of the locking shaft 531-3 is fixedly connected to the handle 531-4. After the quick-release connecting plate 403 of the flipping brick-laying mechanism 400 has two bayonets stuck on the smooth shaft 531-7 and the locking shaft 531-3, and the handle 531-4 is rotated to make the locking shaft 531-3 rotate to clamp the laying mechanism, so that the laying mechanism and the quick-release mounting bracket 531 are locked and fixedly connected. A buckle 531-5 for fixing the handle 531-4 is arranged on the outer side of one of the triangular plates to keep the handle 531-4 fixed in the locked state.

[0093] The mechanical boom 500 can realize the longitudinal and vertical positioning of the flipping brick-laying mechanism 400 installed at the front part and provide support for it. Through the coordinated operation of the vertical lifting mechanism 505, the horizontal pushing mechanism 506 of the mechanical boom 500 and the swing cylinder 532, it can be ensured that the front flipping brick-laying mechanism 400 always maintains a horizontal state, which is convenient for ground leveling, floor tile placement, floor tile rolling, etc.

[0094] A quick-release mounting bracket 531 is installed at the bottom of the outrigger 530, facilitating quick connection with the quick-release connecting plate 403 on the main frame of the tilting brick-laying mechanism 400. By extending and retracting the swing cylinder 532, the angle of the quick-release mounting bracket 531 can be adjusted, facilitating quick positioning and combination of the connection structure with the tilting brick-laying mechanism 400, achieving quick installation and disassembly.

[0095] In some other embodiments, we can also remove the tilting brick-laying mechanism 400 from the mechanical boom 500 and replace it with other mechanisms. For example, the tilting brick-laying mechanism 400 for laying floor tiles can be replaced with a mechanism for laying curb stones, thereby meeting different brick-laying requirements. At the same time, the lifting mechanism 100, the clamping and pushing mechanism 200, and the conveying mechanism 300 on the vehicle frame do not need to be modified, making the expandability of the present invention stronger.

[0096] The working process of the present invention will be described in detail below:

[0097] First, the floor tiles 01 are stacked on the forks of the forklift, with the front and back sides of the stacked floor tiles 01 in contact. Subsequently, we lower the storage bracket 130 to a horizontal state and drive the forklift to transfer the stacked floor tiles to the storage bracket 130. Since the storage bracket 130 is rotatably connected to the center of the bottom of the longitudinal lifting bracket 102, a space for the forklift to travel is formed on both sides of the storage bracket 130. When the forklift travels near the flat brick-laying device 10, the storage bracket 130 can extend into the center of the opening of the forks. After the forklift is in place, it unloads the floor tiles and leaves.

[0098] A second transmission mechanism 132 with rollers or belts is provided on the storage bracket 130, and the stacked floor tiles 01 are conveyed forward to the lifting plate 103 by the second transmission mechanism 132. The ejector rods of the lifting devices 120 on both sides of the lifting plate 103 slide upward, and the ejector rods drive the lifting webs 106 on both sides to move upward steadily through the lifting chains 122, thereby raising the height of the lifting plate 103 as Figure 3b shown.

[0099] The clamping device 220 of the clamping and pushing mechanism 200 slides backward towards the rear of the vehicle, and the clamping plates 225 clamp and fix the left and right ends of the topmost floor tile 01. Subsequently, the clamping device 220 moves towards the front of the vehicle. During the forward sliding process of the clamping device 220, the second roller 221 will slide into the lower lifting track 213 to raise its own height, so that the clamping device 220 slightly raises the height of the floor tile 01 while driving the floor tile 01 forward, avoiding scratching between the clamped floor tile 01 and the floor tile 01 on the lifting plate 103, thereby affecting the appearance of the floor tile 01.

[0100] When the clamping device 220 slides on the forward moving guide rail 210 to above the conveying mechanism 300, the two clamping plates 225 are loosened, and the floor tile 01 drops onto the conveying mechanism 300, and the conveying mechanism 300 continues to convey the lying floor tile 01 forward.

[0101] After the vehicle frame moves to the designated position in the paving area, the positioning mechanism 320 is used to position the flipping brick paving mechanism 400. The flipping oil cylinder 434 drives the whole flipping mechanism 430 to flip, so that the serrated scraper of the leveling mechanism 432 contacts the ground obliquely. Subsequently, the horizontal telescopic cylinder 406 drives the flipping mechanism 430 to move back and forth as a whole on the setting frame to level the ground, as Figure 6g shown.

[0102] After the ground is leveled, the floor tile conveyed by the conveying mechanism 300 is transferred to between the support plate 407 and the support brackets 431-4 and 431-5 through the support plate 407, so that the brick is clamped by the placing mechanism 431. Subsequently, the flipping oil cylinder 434 drives the whole flipping mechanism 430 to flip, so that the placing mechanism 431 with the brick clamped at the rear side flips to the front side and becomes horizontal, as Figures 6h - 6i shown. Subsequently, the horizontal telescopic cylinder 406 drives the flipping mechanism 430 to retract, and the support bracket 431-5 is withdrawn from the gap between the floor tile 01 and the ground. At this time, the laying of the floor tile 01 on the ground is completed.

[0103] Subsequently, the flipping oil cylinder 434 drives the whole flipping mechanism 430 to flip, so that the flipping of the rolling mechanism 433 makes the rolling wheel contact the upper surface of the laid floor tile. Subsequently, the horizontal telescopic cylinder 406 drives the flipping mechanism 430 to move back and forth, and the rolling wheel rolls the upper surface of the laid floor tile back and forth, as Figure 6j shown.

[0104] After the rolling is completed, the horizontal telescopic cylinder 406 drives the flipping mechanism 430 to retract to the initial position, and the flipping oil cylinder 434 drives the flipping mechanism 430 to flip to the state where the placing mechanism 431 is connected to the conveying mechanism 300 (that is, return to Figure 6e the state). Subsequently, the vehicle body moves to the next brick laying position, and two sets of positioning mechanisms are used to provide positioning to ensure that the laid bricks fall into the designated position.

[0105] The mechanical boom 500 is used to support the flipping brick paving mechanism 400. When the flat brick laying equipment is in the non-laying working state, the mechanical boom 500 slides upward on the vertical guide rail 501 to drive the flipping brick paving mechanism 400 to leave the ground and suspend it, so as to protect the flipping brick paving mechanism 400; when the flat brick laying equipment moves to the designated position, the mechanical boom 500 descends, and the horizontal pushing mechanism 506 drives the legs 530 to move horizontally back and forth to adjust the position of the flipping brick paving mechanism 400 at the bottom of the mechanical boom 500.

It should be understood that the present invention is not limited to the above specific embodiments, and the devices and structures not described in detail should be understood to be implemented in a common manner in the art; any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention, which does not affect the essence of the present invention.
