[0001] This utility model relates to the field of road and bridge engineering technology, and in particular to a road surface paving device for roads and bridges. Background Technology

[0002] With the development of urbanization, this device is used when paving concrete pavement of roads and bridges. When building new roads and bridges, it is necessary to lay high-quality pavement. This device can effectively improve the smoothness, density and other quality indicators of concrete pavement. When repairing or renovating roads and bridges, this device is also needed to ensure that the newly paved concrete achieves good construction results.

[0003] However, in actual use, paving devices with similar structures still have many defects.

At the same time, existing paving devices may have problems such as uneven compaction and difficulty in effectively eliminating gaps during the compaction process. Therefore, it is necessary to design a road surface paving device for roads and bridges. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a road surface paving device for roads and bridges.

[0005] This utility model is achieved using the following technical solution: a road surface paving device for roads and bridges, comprising a paving assembly, the paving assembly including a mounting frame, an anti-overflow plate rotatably mounted inside the mounting frame, a paving screw rotatably mounted on the inner wall of the mounting frame at the rear end of the anti-overflow plate, and a paving roller rotatably mounted on the inner wall of the mounting frame at the rear end of the paving screw, further comprising:

[0009] The above technical solution provides a stable power source for the entire leveling device, realizes the effective transmission of power, and ensures that the subsequent dispersing roller and leveling screw can rotate normally, thereby realizing the dispersing and leveling operation of concrete and improving the working efficiency of the device.

[0010] As a further improvement to the above solution, the first force-bearing bevel gear has an installation groove inside, and the outer surface of the second force-bearing bevel gear is fixedly installed with an embedded block. The embedded block matches the installation groove. A rotating rod is fixedly installed on the side of the outer surface of the second force-bearing bevel gear away from the embedded block.

This, in turn, stably drives the rotation of related components, which is beneficial for concrete processing and improves the reliability of the device operation.

[0012] As a further improvement to the above solution, a first transmission chain is sleeved on the outer surface of the first force-bearing bevel gear, and the side of the first transmission chain away from the first force-bearing bevel gear is sleeved on the outer surface of the dispersing roller.

[0015] The above technical solution ensures that the leveling screw can receive stable power input, enabling the leveling screw to rotate and initially level the concrete.

[0018] Through the above technical solutions, the buffer spring ensures that the descent speed of the vibratory compaction plate is moderate, and the guide rod ensures that the movement direction of the vibratory compaction plate is accurate, thereby effectively compacting the voids in the paved concrete, improving the density of the road surface, enhancing the load-bearing capacity of the road surface, and extending the service life of roads and bridges.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0030] Please combine Figure 1-5 This embodiment of a road and bridge pavement paving device includes a paving assembly 1. The paving assembly 1 includes a mounting frame 101. An anti-overflow plate 102 is rotatably mounted inside the mounting frame 101. A paving screw 104 is rotatably mounted on the inner wall of the mounting frame 101 at the rear end of the anti-overflow plate 102. A paving roller 105 is rotatably mounted on the inner wall of the mounting frame 101 at the rear end of the paving screw 104. The device also includes:

[0031] Drive assembly 2 includes a mounting base 201 fixedly mounted on the top of mounting bracket 101, a first force-bearing bevel gear 202 rotatably mounted inside the mounting base 201, and a second force-bearing bevel gear 203 rotatably mounted on the outer surface of the first force-bearing bevel gear 202.

[0032] The vibration compaction assembly 3 includes a support frame 301 fixedly installed on the outer surface of the mounting frame 101, and a reciprocating rod 305 is slidably installed inside the support frame 301.

[0033] A support frame 205 is fixedly installed on the top of the mounting bracket 101. A first servo motor 206 is fixedly installed inside the support frame 205. A drive bevel gear 207 is fixedly installed at the output end of the first servo motor 206. The drive bevel gear 207 meshes with the first force bevel gear 202 and the second force bevel gear 203.

[0034] The first force-bearing bevel gear 202 has an internal mounting groove. The outer surface of the second force-bearing bevel gear 203 is fixedly mounted with an embedded block, which matches the mounting groove. A rotating rod 204 is fixedly mounted on the outer surface of the second force-bearing bevel gear 203 away from the embedded block. The rotating rod 204 is rotatably mounted inside the support frame 205.

[0035] A first transmission chain 106 is sleeved on the outer surface of the first force-bearing bevel gear 202, and the side of the first transmission chain 106 away from the first force-bearing bevel gear 202 is sleeved on the outer surface of the dispersing roller 103.

[0036] The second transmission chain 107 is sleeved on the outer surface of the second force-bearing bevel gear 203, and the side of the second transmission chain 107 away from the second force-bearing bevel gear 203 is sleeved on the outer surface of the flattening screw 104.

[0037] When the drive bevel gear 207 rotates, the first force bevel gear 202 and the second force bevel gear 203 will rotate in opposite directions. The first force bevel gear 202 transmits power to the dispersing roller 103 through the first transmission chain 106, causing it to rotate. The second force bevel gear 203 transmits power to the leveling screw 104 through the second transmission chain 107, causing it to rotate. The opposite rotation of the dispersing roller 103 and the leveling screw 104 disperses the laid concrete.

[0038] A second servo motor 302 is fixedly installed on the outer surface of the support frame 301. A drive rod 303 is fixedly connected to the output end of the second servo motor 302. A connecting rod 304 is rotatably installed on the outer surface of the drive rod 303. A connecting seat is fixedly installed on the top of the reciprocating rod 305. The connecting rod 304 is rotatably installed inside the connecting seat.

[0039] A buffer spring 306 is fixedly connected between the connecting seat and the mounting bracket 101. A vibration compaction plate 307 is fixedly installed at the bottom of the reciprocating rod 305. A guide rod 308 is fixedly installed on the outer surface of the mounting bracket 101. The vibration compaction plate 307 is slidably installed on the outer surface of the guide rod 308.

[0040] During the reciprocating motion of the vibratory compaction plate 307, the buffer spring 306 between the connecting seat and the mounting frame 101 plays a buffering role. When the vibratory compaction plate 307 descends, the buffer spring 306 is compressed. Its elasticity ensures that the speed at which the vibratory compaction plate 307 descends is not too fast, thereby avoiding excessive impact on the concrete and ensuring the uniformity of the compaction effect.

[0041] The implementation principle of a road and bridge pavement paving device in this embodiment is as follows: When the device is started, the first servo motor 206 starts working, and the drive bevel gear 207 at its output end rotates. Since the drive bevel gear 207 meshes with the first force-bearing bevel gear 202 and the second force-bearing bevel gear 203, and the first force-bearing bevel gear 202 and the second force-bearing bevel gear 203 are located on both sides of the drive bevel gear 207, when the drive bevel gear 207 rotates, the first force-bearing bevel gear 202 and the second force-bearing bevel gear 203 mesh. 3. They will rotate in opposite directions. The first force bevel gear 202 transmits power to the dispersing roller 103 through the first transmission chain 106, causing it to rotate. The second force bevel gear 203 transmits power to the leveling screw 104 through the second transmission chain 107, causing it to rotate. The opposite rotation of the dispersing roller 103 and the leveling screw 104 disperses the concrete. The dispersing roller 103 can break up lumps in the concrete. The leveling screw 104 initially levels the concrete and transports it backward while dispersing it.

[0042] After the concrete is broken up and initially leveled, the leveling screw 104 transports the concrete to the leveling roller 105. The leveling roller 105 is located behind the leveling screw 104 in the structure of the device. It spreads the received concrete evenly in all directions, so that the concrete initially forms a flat state on the road surface. During the concrete filling process, the overflow plate 102 can limit the flow range of the concrete in the device, ensuring that the concrete can be transported, broken up, leveled and compacted according to the predetermined path. At the same time, the second servo motor 302 starts to work, and the drive rod 303 at its output end rotates. The drive rod 303 drives the connecting rod 304 to move up and down reciprocatingly. Since the bottom of the connecting rod 304 is rotated and installed in the connecting seat at the top of the reciprocating rod 305, the up and down reciprocating motion of the connecting rod 304 drives the reciprocating rod 305 to move continuously reciprocatingly.

[0043] The vibratory compaction plate 307 at the bottom of the reciprocating rod 305 moves together with the reciprocating rod 305, performing high-frequency vibration compaction on the concrete that has just been spread by the leveling roller 105. The guide rod 308 fixedly installed on the outer surface of the mounting frame 101 provides guidance for the up and down movement of the vibratory compaction plate 307, ensuring that the movement direction of the vibratory compaction plate 307 is accurate. During the reciprocating movement of the vibratory compaction plate 307, the buffer spring 306 between the connecting seat and the mounting frame 101 plays a buffering role. When the vibratory compaction plate 307 descends, the buffer spring 306 is compressed, and its elasticity ensures that the speed at which the vibratory compaction plate 307 descends is not too fast, thereby avoiding excessive impact on the concrete and ensuring the uniformity of the compaction effect.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
