Abstract
Description
Technical Field
[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a road paving device for road and bridge construction. Background Technology
[0002] Road and bridge construction refers to the process of building roads and bridges. With the development of society, the demand for roads and bridges is increasing, and the construction of roads and bridges is becoming more and more frequent.
[0003] During road and bridge construction, it is necessary to level the concrete of the road surface or bridge deck. Generally, road paving equipment is required. However, when paving in areas where large equipment cannot reach, traditional road paving equipment used in road and bridge construction is mostly a hand-held roller. After the concrete is poured, the road surface is leveled by pushing the hand-held roller back and forth. This method is inefficient and labor-intensive in long-term operation. Therefore, we have proposed a road paving device for road and bridge construction to solve the above problems. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies that involve flattening the road surface by repeatedly pushing a handheld roller after concrete is poured, which is inefficient and labor-intensive over long periods. It provides a road paving device for road and bridge construction.
[0005] This utility model is achieved through the following technical solution:
[0006] A road paving device for road and bridge construction includes limiting baffles that cover both sides of the road during paving, a retracting mechanism and a transmission mechanism installed at the ends of the limiting baffles on both sides, and a flattening mechanism slidably installed between the limiting baffles on both sides. The flattening mechanism includes a paving block and connecting plates inserted at both ends of the paving block. The connecting plates are slidably connected to the paving block, and a sliding seat is provided at the outer end of the connecting plate. The sliding seat is slidably connected to the top of the limiting baffle.
[0007] The take-up and release mechanism includes a first take-up and release roller and a second take-up and release roller. A first gear and a second gear that mesh with each other are respectively installed at one end of the first take-up and release roller and the second take-up and release roller, and a servo motor for driving is provided at the outer end of the second take-up and release roller.
[0008] The transmission mechanism includes a transmission roller and a guide wheel fixed on the transmission roller. A first connecting rope is wound on the first take-up roller and a second connecting rope is wound on the second take-up roller. The outer end of the first connecting rope rests on the guide wheel and is fixedly connected to one side of the paving block, and the outer end of the second connecting rope is fixedly connected to the other side of the paving block.
[0009] In a preferred embodiment of this utility model, each of the limiting baffles is composed of multiple limiting plates spliced together. One end of two adjacent limiting plates is provided with a matching "concave" and "convex" shaped snap-fit structure, and the top of the limiting plate has a T-shaped slide rail. The limiting baffle is used to restrict the two sides of the concrete during paving, and the fact that it is composed of multiple limiting plates facilitates the transportation and storage of the limiting baffle.
[0010] In a preferred embodiment of this utility model, the slide block is mounted on the T-shaped slide rail, and multiple guide rods are fixed on the inner side wall of the slide block. The connecting plate is slidably connected to the inner side wall of the slide block in the vertical direction, and the guide rods pass through the connecting plate. A spring is sleeved on the lower end of the guide rods. The spring is located at the bottom of the connecting plate. The spring reduces the vibration of the limiting baffle when the vibration motor is working.
[0011] In a preferred embodiment of this utility model, the bottom ends of both sides of the paving block are provided with inclined angles, and both ends of the paving block are provided with sliding cavities. The connecting plate is inserted into the sliding cavity, and multiple adjusting screw holes are linearly provided on the connecting plate. Locking bolts that are adapted to the adjusting screw holes are provided at both ends of the paving block. By adjusting the length of the connecting plates on both sides in the paving block, the relative position between the paving block and the limiting baffles on both sides is adjusted, thereby allowing the paving of different widths of road surface to be laid.
[0012] In a preferred embodiment of this utility model, a vibration motor is installed on the paving block.
[0013] In a preferred embodiment of this utility model, multiple support bars are provided between the limiting baffles on both sides. The support bars are snapped onto the limiting baffles. The support bars can support the first connecting rope and the second connecting rope, so that the first connecting rope and the second connecting rope do not come into contact with the concrete pavement during long-distance traction.
[0014] The beneficial effects of the utility model are:
[0015] This device uses a servo motor to drive the paving blocks to reciprocate and level the concrete road surface by alternating forward and reverse rotation. It reduces the labor intensity of manual operation and improves work efficiency through semi-automation.
[0016] By installing a vibratory motor on the paving blocks, the concrete pavement is vibrated during the initial paving operation, allowing the concrete to penetrate into the foundation and improving the strength of the pavement after it is laid. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.
[0022] like Figure 1-3 The diagram shows a road paving device for road and bridge construction, used to pave concrete road surfaces. It includes limiting baffles 1 that shield both sides of the road during paving. Each limiting baffle 1 is composed of multiple limiting plates spliced together. One end of two adjacent limiting plates is provided with a matching "concave" and "convex" shaped snap-fit structure, and the top of the limiting plate has a T-shaped slide rail. The limiting baffles 1 are used to restrict both sides of the concrete during paving. At the same time, the multiple limiting plates spliced together facilitate the transportation and storage of the limiting baffles 1. During paving, the concrete is poured between the two limiting baffles 1. The distance between the two limiting baffles 1 is the width of the road surface to be paved. It also includes a retraction mechanism and a transmission mechanism installed at the ends of the two limiting baffles 1.
[0023] A flattening mechanism is slidably installed between the two limiting baffles 1. The flattening mechanism includes a flattening block 6 and connecting plates 8 inserted at both ends of the flattening block 6. The connecting plates 8 are slidably connected to the flattening block 6. Each end of the flattening block 6 has a sliding cavity 61. The connecting plates 8 are inserted into the sliding cavity 61, and multiple adjusting screw holes 81 are linearly opened on the connecting plates 8. Both ends of the flattening block 6 are provided with locking bolts 9 that are adapted to the adjusting screw holes 81. By adjusting the length of the connecting plates 8 on both sides in the flattening block 6, the flattening block 6 and the two limiting baffles 1 are flattened. The relative positions between the baffles 1 can be adjusted to pave roads of different widths. The outer end of the connecting plate 8 is provided with a slide block 10, which is slidably connected to the top of the limiting baffle 1. The slide block 10 is installed on the T-shaped slide rail, and multiple guide rods 101 are fixed on the inner side wall of the slide block 10. The connecting plate 8 is slidably connected to the inner side wall of the slide block 10 in the vertical direction. The guide rods 101 pass through the connecting plate 8, and a spring 102 is sleeved on the lower end of the guide rods 101. The spring 102 is located at the bottom of the connecting plate 8.
[0024] It should be noted that the bottom of both sides of the paving block 6 is provided with an inclined angle. The inclined angle allows the concrete to flow to the bottom of the paving block 6 during laying, reducing the pressure of the side wall of the paving block 6 on the concrete.
[0025] Secondly, the take-up and release mechanism includes a first take-up and release roller 2 and a second take-up and release roller 3. A first gear 21 and a second gear 31 that mesh with each other are respectively installed at one end of the first take-up and release roller 2 and the second take-up and release roller 3, and a servo motor 4 for driving is provided at the outer end of the second take-up and release roller 3.
[0026] The transmission mechanism includes a transmission roller 5 and a guide wheel 51 fixed on the transmission roller 5. A first connecting rope 11 is wound on the first take-up roller 2 and a second connecting rope 12 is wound on the second take-up roller 3. The outer end of the first connecting rope 11 is placed on the guide wheel 51 and fixedly connected to one side of the paving block 6. The outer end of the second connecting rope 12 is fixedly connected to the other side of the paving block 6.
[0027] Furthermore, a vibration motor 7 is installed on the paving block 6, which vibrates the concrete pavement, allowing the concrete to penetrate into the foundation and improve the strength of the pavement after it is laid. The spring 102 reduces the vibration of the limit baffle 1 when the vibration motor 7 is working.
[0028] Meanwhile, multiple support bars 13 are provided between the two limiting baffles 1. The support bars 13 are snapped onto the limiting baffles 1. The support bars 13 can support the first connecting rope 11 and the second connecting rope 12, so that the first connecting rope 11 and the second connecting rope 12 do not come into contact with the concrete pavement during long-distance traction.
[0029] In this embodiment, the limiting baffle 1 is first fixed, and concrete is poured between the two limiting baffles 1. The take-up and release mechanism and the transmission mechanism are fixed at both ends of the road surface to be paved. The second take-up and release roller 3 is driven to rotate by the operation of the servo motor 4, and the first take-up and release roller 2 is driven to rotate in the opposite direction to the second take-up and release roller 3 by the meshing of the first gear 21 and the second gear 31. This allows the first connecting rope 11 to be taken up while the second connecting rope 12 is released, thereby pulling the paving block 6 to move and paving the concrete road surface.
[0030] During the paving process, the vibrating motor 7 vibrates the concrete pavement, allowing the concrete to penetrate into the foundation and reducing the gaps between the concrete blocks, thereby improving the strength of the paved pavement. When the paving block 6 moves for the last time, the vibrating motor 7 is turned off, allowing it to run one more paving stroke to level the pavement.
[0031] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
[0032] In the description of the embodiments of this utility model, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "set up," "equipped with," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
