Description

Technical Field

[0001] This utility model relates to the field of block laying technology, specifically to a road block laying device. Background Technology

[0002] With the acceleration of urbanization, road construction, as an important part of urban infrastructure construction, is constantly expanding in scale and demand. In road paving construction, block paving is a common construction process. Its construction quality and efficiency directly affect the performance and aesthetics of the road. In order to improve the quality and efficiency of road block paving and reduce labor costs, various road block paving devices have emerged and have been applied in actual projects.

[0003] According to Chinese Patent No. CN218712023U, a brick laying device is disclosed, comprising a chassis, rollers, and a pressure plate. Rotary rods pass through both sides of the chassis, and rollers are installed at both ends of the rotating rods extending from the chassis. A fixed frame is connected to one edge of the chassis. A first fixed rod passes through the lower part between the inner walls of both sides of the fixed frame. A flipping plate is fitted onto the first fixed rod. A telescopic rod is rotatably connected between the flipping plate and the top of the fixed frame. A second spring is fitted onto the telescopic rod, and both ends of the second spring are connected to the flipping plate and the fixed frame, respectively. A pressure plate is connected to the end of the flipping plate away from the fixed frame. When a cylinder is activated, a pusher plate moves back and forth on the chassis, sequentially pushing bricks from the inner wall of the storage frame into a feeding frame. The feeding frame guides the bricks to the ground, automatically discharging them along the device's movement path. This makes operation more labor-saving, convenient, and improves work efficiency.

[0004] In the above solution, it was found that the storage box of the device lacks limiting and correction measures, which makes it easy for bricks to shift and tilt when placed. This not only causes jamming due to positional deviation during the pushing process, affecting paving efficiency, but may also result in uneven arrangement of bricks after paving, reducing the overall quality of road paving. In addition, different engineering projects use bricks of various sizes and specifications, and traditional devices are difficult to meet the needs of precise limiting and correction of bricks of different sizes. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a road block paving device that has the advantages of orderly storage and output of blocks, adaptability to blocks of different sizes, block positioning and correction, and good compaction effect. This solves the problems of traditional paving devices being laborious to operate, unable to effectively handle block skewing and jamming, having poor versatility, and being unable to guarantee paving quality.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: a road block paving device, including a base plate, with movable wheels at the bottom of the base plate, a storage frame fixedly installed on the top of the base plate, a discharge port on one side of the storage frame, a guide groove fixedly installed on one side of the storage frame, a rectangular hole on the other side of the storage frame, a limiting frame fixedly installed on the other side of the storage frame, a cylinder fixedly installed on the top of the base plate, a push rod fixedly installed on the movable end of the cylinder, the limiting frame cooperating with the push rod, an L-shaped bracket fixedly installed on the top of the base plate, two movable holes on both sides of the storage frame, a limiting and correcting component for correcting the brickwork inside the storage frame, the movable holes cooperating with the limiting and correcting component, and a compaction component at one end of the L-shaped bracket.

[0007] As a preferred embodiment of this utility model, the limiting correction component includes two extrusion plates, which are symmetrically arranged inside the storage frame.

A limiting disc is fixedly installed at the other end of each movable rod. A first spring is fixedly installed on one side of each extrusion plate, and the other end of the first spring is fixedly installed inside the storage frame. A limiting hole is formed on the side of the extrusion plate near the first spring.

[0008] As a preferred technical solution of this utility model, the limiting correction component further includes a rectangular mounting hole, which is opened on one side of the extrusion plate. Two connecting plates are movably installed inside the rectangular mounting hole. Several second springs are fixedly installed between the two connecting plates. Limiting blocks are fixedly installed on the side of the two connecting plates near the limiting hole. The limiting blocks are used in conjunction with the limiting hole. Side pressure plates are fixedly installed on one side of the two connecting plates.

[0009] As a preferred embodiment of this utility model, the compaction component includes a motor, which is fixedly mounted on the top of an L-shaped bracket. A cam is fixedly mounted on the output end of the motor. A circular hole is opened on the top of the base plate, and a pressing rod is movably mounted inside the circular hole. The cam works in conjunction with the pressing rod. A limiting disc is fixedly mounted on the top of the pressing rod, and a third spring is fixedly mounted on the bottom of the limiting disc. The other end of the third spring is fixedly mounted to the top of the base plate, and a pressing plate is fixedly mounted on the bottom of the pressing rod.

[0010] As a preferred technical solution of this utility model, the top of the push rod is provided with a rectangular groove, and several rotating rollers are rotatably installed inside the rectangular groove. The side pressure plate near the discharge port is relatively short and flush with the top of the discharge port, so that it will not obstruct the block during the process of the block being pushed out of the discharge port.

[0011] As a preferred embodiment of this utility model, threaded holes are provided on both sides of the guide groove, and an adjusting bolt is threadedly connected inside the threaded hole. A discharge baffle is movably installed at the other end of the adjusting bolt.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention features movable wheels, making the device easy to move and allowing it to flexibly reach different construction sites. The combination of the storage frame and the discharge port enables the orderly storage and output of blocks. The combination of the cylinder and push rod, with the assistance of the limiting frame, can stably push the blocks out of the discharge port.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 5 The present invention will be further described below.

[0023] A road block paving device includes a base plate 1 with casters at the bottom and a storage frame 2 fixedly mounted on the top. A discharge port 3 is provided on one side of the storage frame 2, and a guide groove 4 is fixedly mounted on one side. A rectangular hole is provided on the other side of the storage frame 2, and a limiting frame 20 is fixedly mounted on the other side. A cylinder 5 is fixedly mounted on the top of the base plate 1, and a push rod 6 is fixedly mounted on the movable end of the cylinder 5. The limiting frame 20 works in conjunction with the push rod 6. An L-shaped bracket 7 is fixedly mounted on the top of the base plate 1. Two movable holes are provided on both sides of the storage frame 2. A limiting and correcting component for adjusting the brickwork is provided inside the storage frame 2. The movable holes work in conjunction with the limiting and correcting component. A compaction component is provided at one end of the L-shaped bracket 7.

[0024] In this implementation scheme, a base plate 1 provides a stable installation platform for other components, ensuring that all components can work together. The moving wheels bear the weight of the device and reduce friction with the ground, making it easier for operators to push the device. The storage box 2 stores a large number of bricks to be laid, reducing the frequency of brick replenishment and ensuring the continuity of construction. The discharge port 3 is the key channel for bricks to enter the paving process from the storage box 2, and works with the guide groove 4 to guide the bricks to be laid in a predetermined direction. The guide groove 4 guides the pushed-out bricks, ensuring their straightness and neatness, improving the aesthetics and quality of the road paving. The limiting frame 20 works with the push rod 6 to precisely limit the movement trajectory of the push rod 6, ensuring that the push rod 6... The cylinder 5 provides stable power to the push rod 6, driving it to push the brick out of the storage frame 2. The roller in the rectangular groove at the top of the push rod 6 reduces friction with the brick, minimizing damage and ensuring a smoother pushing process. The L-shaped bracket 7 provides a stable mounting base for the compaction component. The limit and correction component limits and corrects the brick in the storage frame 2, preventing deviation and tilting, and adapting to different brick sizes. The compaction component compacts the brick laid on the ground, ensuring a tight fit and enhancing the stability and strength of the road paving, thus improving road quality. The cylinder 5 can be driven directly by compressed air from the construction site, or an air compressor and air tank can be installed on the base plate 1.

[0025] Specifically, the limit correction assembly includes two extrusion plates 13, which are symmetrically arranged inside the storage frame 2. Two movable rods 14 are fixedly installed on one side of the extrusion plate 13. The movable rods 14 are movably sleeved inside the movable holes. A limit disc is fixedly installed on the other end of the movable rods 14. A first spring 15 is fixedly installed on one side of the extrusion plate 13. The other end of the first spring 15 is fixedly installed inside the storage frame 2. A limit hole is opened on the side of the extrusion plate 13 near the first spring 15.

[0026] In this embodiment, by setting up an extrusion plate 13, which acts directly on the bricks, the extrusion plate 13 can provide a suitable limiting space for the bricks by moving and adjusting itself to accommodate bricks of different sizes. For smaller bricks, under the elastic force of the first spring 15, the extrusion plate 13 moves inward to reduce the gap around the brick and prevent the brick from shaking or shifting. For larger bricks, the extrusion plate 13 is stretched open when the brick is placed in, but it still maintains contact and constraint on the side of the brick. Its main function is to limit and correct the brick. When the brick is shifted or tilted in the storage frame 2, the extrusion plate 13 applies extrusion force to the brick under the elastic force of the first spring 15, pushing the brick back to the correct position. This ensures that the bricks remain relatively neat in the storage frame 2 and avoids jamming during subsequent ejection due to brick position deviation. The movable rod 14 allows the extrusion plate 13 to move flexibly to adapt to the needs of different sized bricks, providing a guide for the movement of the extrusion plate 13 and ensuring that the extrusion plate 13 stably performs limiting and correction operations on the bricks in the horizontal direction. The limiting disc prevents the movable rod 14 from coming out of the movable hole. For smaller bricks, the first spring 15 is in a relatively compressed state, continuously providing inward elastic force to the extrusion plate 13, making the extrusion plate 13 tightly fit the side of the brick and prevent it from shaking. For larger bricks, the first spring 15 is stretched, generating outward elastic force to maintain the contact and constraint between the extrusion plate 13 and the brick. When the brick is not placed properly, the first spring 15 is compressed or stretched to generate elastic force, driving the extrusion plate 13 to correct the brick. The limiting hole cooperates with the limiting block to prevent the connecting plate 17 from disengaging from the rectangular mounting hole 16.

[0027] Specifically, the limit correction assembly also includes a rectangular mounting hole 16, which is opened on one side of the extrusion plate 13. Two connecting plates 17 are movably installed inside the rectangular mounting hole 16. Several second springs 19 are fixedly installed between the two connecting plates 17. Limit blocks are fixedly installed on the side of the two connecting plates 17 near the limit hole. The limit blocks are used in conjunction with the limit hole. Side pressure plates 18 are fixedly installed on one side of the two connecting plates 17.

[0028] In this embodiment, by providing rectangular mounting holes 16, movable space is provided for the two connecting plates 17, allowing the connecting plates 17 to flexibly move and adjust their position within the rectangular mounting holes 16 according to different brick sizes. For smaller bricks, the connecting plates 17 can move relatively close within the holes, causing the side pressure plates 18 to fit more tightly against the brick. For larger bricks, the connecting plates 17 can move outward within the holes, allowing the side pressure plates 18 to adapt to the larger brick size. This ensures that the side pressure plates 18 can always effectively limit and correct bricks of different sizes, enhancing the adaptability of the limiting and correction component. The connecting plates 17 can move according to changes in brick size within the rectangular mounting holes 16. The movement within the mounting hole 16 causes the side pressure plate 18 to make corresponding adjustments. The second spring 19 has important buffering and adaptive adjustment functions. When facing bricks of different sizes, the second spring 19 can automatically adjust its elastic force according to the actual situation of the bricklaying, while also providing a certain constraint to the bricklaying, ensuring that the bricklaying remains stable during storage and ejection. This improves the adaptability and stability of the limit correction component to bricks of different sizes. The limit block works in conjunction with the limit hole on the extrusion plate 13 to limit the movement range of the connecting plate 17. The side pressure plate 18 directly contacts the side of the bricklaying. For bricks of different sizes, the side pressure plate 18 can make corresponding adjustments according to the movement of the connecting plate 17.

[0029] Specifically, the compaction component includes a motor 8, which is fixedly mounted on the top of the L-shaped bracket 7. A cam 9 is fixedly mounted on the output end of the motor 8. A circular hole is opened on the top of the base plate 1, and a pressing rod 10 is movably mounted inside the circular hole. The cam 9 and the pressing rod 10 are used in conjunction. A limiting disc is fixedly mounted on the top of the pressing rod 10, and a third spring 11 is fixedly mounted on the bottom of the limiting disc. The other end of the third spring 11 is fixedly mounted to the top of the base plate 1, and a pressing plate 12 is fixedly mounted on the bottom of the pressing rod 10.

[0030] In this embodiment, a motor 8, connected to an external power source, provides power to the compaction component, driving the cam 9 to rotate. The cam 9 rotates along with the motor 8, converting the circular motion of the motor 8 into the vertical linear motion of the pressing rod 10. When the protruding part of the cam 9 contacts the pressing rod 10, it pushes the pressing rod 10 downwards. When the protruding part leaves the pressing rod 10, the pressing rod 10 returns to its original position under the action of the third spring 11, thus realizing the reciprocating motion of the pressing rod 10. The pressing rod 10 works in conjunction with the cam 9, transmitting the motion of the cam 9 to the pressing plate 12, enabling the pressing plate 12 to compact the laid road blocks. During the compaction operation, the limiting disc prevents the pressing rod 10 from dislodging from the circular hole when it moves up and down. When the cam 9 pushes the pressing rod 10 downward, the third spring 11 is compressed. When the protrusion of the cam 9 leaves the pressing rod 10, the elastic restoring force of the third spring 11 causes the pressing rod 10 to return to its original position, preparing for the next compaction action and ensuring the continuity of the compaction process. The pressing plate 12 is the component that directly contacts and compacts the road blocks. It has a large contact area and can evenly apply the force transmitted from the pressing rod 10 to the road blocks, making the blocks fit tightly against the ground and improving the flatness and stability of the road.

[0031] Specifically, the top of the push rod 6 is provided with a rectangular groove, and several rotating rollers are rotatably installed inside the rectangular groove. The side pressure plate 18 near the discharge port 3 is relatively short and flush with the top of the discharge port 3, so that it will not obstruct the block during the process of the block being pushed out of the discharge port 3.

[0032] In this embodiment, by setting a rectangular groove at the top of the push rod 6 and a rotating roller, the rotating roller directly contacts the block during the process of the block being pushed out of the storage frame 2 through the discharge port 3. When the push rod 6 pushes the block, the rotating roller rotates in the rectangular groove, which transforms the original sliding friction between the push rod 6 and the block into rolling friction, reducing the friction between the two and making the pushing process smoother and reducing wear on the block. The side pressure plate 18 near the discharge port 3 is designed to be flush with the top of the discharge port 3 and relatively short, so that the side pressure plate 18 will not form an obstacle in the movement path of the block when the block is pushed out of the discharge port 3. This avoids the block being stuck during the pushing process due to the side pressure plate 18 being too long or improperly positioned. Although the side pressure plate 18 is short, it can still play a certain role in limiting and correcting the block before it is pushed out.

[0033] Specifically, threaded holes are provided on both sides of the guide groove 4, and adjusting bolts are connected to the internal threads of the threaded holes. A discharge baffle is movably installed on the other end of the adjusting bolts.

[0034] In this implementation scheme, threaded holes on both sides of the guide groove 4 provide installation positions for the adjusting bolts, enabling the adjusting bolts to be stably connected to the guide groove 4. Through the threaded engagement, the adjusting bolts can be precisely screwed in or out within the threaded holes, thereby achieving fine adjustment of the position of the discharge baffle. By rotating the adjusting bolts, their position within the threaded holes can be changed. When it is necessary to accommodate blocks of different sizes, the operator can manually rotate the adjusting bolts according to the actual width of the blocks. The discharge baffle directly controls the width of the discharge port 3. The discharge baffle can precisely control the size of the discharge port 3 according to the adjustment of the adjusting bolts, preventing the blocks from getting stuck or shaking during the discharge process. The discharge baffle can also play a certain guiding role, working in conjunction with the guide groove 4 to further guide the blocks to be pushed out in the correct direction, improving the accuracy of block laying.

[0035] In summary: When using this utility model, the device is first moved to the construction site by the moving wheels. The blocks to be laid are then manually placed into the limiting and correcting assembly inside the storage frame 2. Two pressing plates 13 are symmetrically arranged inside the storage frame 2. When the blocks are placed, for smaller blocks, the first spring 15 is in a relatively compressed state, and its inward elastic force pushes the pressing plates 13 inward, thereby reducing the gap around the blocks and preventing them from shaking or shifting within the storage frame 2. For larger blocks, the pressing plates 13 are stretched when placed, at which point the first spring 15 is stretched, generating an outward elastic force to maintain contact and constraint between the pressing plates 13 and the sides of the blocks. Two movable rods 14 fixed on one side of the pressing plates 13 are movably sleeved in the movable holes on both sides of the storage frame 2, providing guidance for the movement of the pressing plates 13 and ensuring stable limiting and correcting of the blocks in the horizontal direction. When facing smaller blocks, the second spring 19 is relatively compressed, causing the two connecting plates 17 to move closer together within the rectangular mounting holes 16, driving the side pressure... Plate 18 fits more tightly against the block. For larger blocks, the second spring 19 is stretched, and connecting plate 17 moves outward within the hole, allowing side pressure plate 18 to adapt to the larger block size. In this way, side pressure plate 18 can always effectively limit and correct blocks of different sizes. After the limiting and correction are completed, cylinder 5 is activated, and its movable end push rod 6 pushes the block under the constraint of limit frame 20. The block enters guide groove 4 through discharge port 3. The operator adjusts the block by rotating the adjusting bolts in the threaded holes on both sides of guide groove 4. The material baffle position controls the size of the discharge port 3, preventing the blocks from getting stuck or shaking, and guiding them to be pushed out in the correct direction. After the blocks are laid on the ground, the motor 8 installed on the top of the L-shaped bracket 7 is started. The motor 8 drives the cam 9 to rotate. The cam 9 converts the circular motion into the up and down linear motion of the pressing rod 10. The limiting disc at the top of the pressing rod 10 prevents it from coming out of the round hole. The pressing plate 12 at the bottom, with the cooperation of the third spring 11, compacts the blocks, making the blocks fit tightly with the ground, improving the stability and quality of the road paving.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
