[0001] This utility model relates to the field of road construction technology, and in particular to a shielding device for preventing the stones from being contaminated during asphalt spraying. Background Technology

[0002] Asphalt pavement is widely used in urban municipal roads. The construction of asphalt concrete pavement for municipal roads generally involves first installing curb stones, then laying the asphalt pavement. The curb stones act as a formwork, ensuring the laid asphalt pavement is neat and without gaps between them. During the spraying of emulsified asphalt, asphalt pollution can occur on hard shoulders, curbs, curb stones, guardrail posts, and other facilities. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a shielding device to prevent the standing stones from being contaminated during asphalt spraying. The shielding device can be easily installed on the standing stones and effectively prevents the standing stones from being contaminated during the asphalt spraying process.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A shielding device for preventing contamination of standing and lying stones during asphalt spraying, capable of shielding both the standing and lying stones, includes: a support frame assembly, the support frame assembly being mounted on the standing stone, and a first shielding plate being provided on the top of the support frame assembly; a second shielding assembly being rotatable relative to the standing stone being provided on the side of the support frame assembly adjacent to it; the second shielding assembly including a second shielding plate rotatably connected to the top of the support frame assembly; a third shielding plate being connected to the second shielding plate being rotatable relative to it; a flexible shielding plate being connected to the lower end of the third shielding plate; the flexible shielding plate being deformable so that a portion of the flexible shielding plate can adhere to the standing stone; and a shielding space being formed between the flexible shielding plate, the third shielding plate, and the second shielding plate to shield the side of the standing stone adjacent to the standing stone.

[0006] The support frame assembly includes multiple support brackets arranged front and rear, each support bracket having a slot for inserting a stepping stone, and a connecting bracket between two adjacent support brackets. A connecting component is also provided between the connecting bracket and the two support brackets to connect and fix the three together, and the first baffle plate is connected to the connecting bracket.

[0007] The support bracket includes two spaced-apart support rods, which are L-shaped. Multiple cross braces connecting the two support rods are provided between them, and a connecting rod is also provided between the two cross braces. The slot is formed between the two support rods.

[0008] The connecting assembly includes a first connecting seat connected to the support rod, the first connecting seat having a first connecting hole, a protruding second connecting seat on the side wall of the connecting bracket having a second connecting hole, and the first connecting hole and the second connecting hole on the same side being on the same axis. The connecting assembly also includes a connecting rod capable of simultaneously passing through each of the first connecting holes and the second connecting holes to connect and fix the first connecting seat and the second connecting seat.

[0009] A hinge is provided between the flexible shielding plate and the third shielding plate to allow the flexible shielding plate and the third shielding plate to be rotatably connected.

[0010] The second shielding plate includes a second frame body arranged in an arc shape, a second plate body connected to the second frame body, and a second support rod that can be connected to the second plate body is also provided in the middle of the second frame body.

[0011] The third shielding plate includes a third frame body, one end of which is rotatably connected to the second frame body. A third plate is provided on the back side of the third frame body, and a third support rod is provided in the middle of the third frame body.

[0012] The flexible shielding plate includes a flexible shielding plate body capable of deformation. The top front and rear sides of the flexible shielding plate body are provided with a first clamping plate and a second clamping plate capable of clamping it. The first clamping plate, the flexible shielding plate body and the second clamping plate are connected and fixed to the hinge by screws.

[0013] The first shield has an outwardly extending flange.

[0014] The first shielding plate is provided with a protruding locking plate, which forms a locking groove for the connecting bracket to be inserted.

[0015] Compared with existing technologies, this invention has the following advantages: In use, the support frame assembly is erected on the base stone. At this time, the first shielding plate covers the top surface of the base stone. Then, the angles of the second shielding plate relative to the support frame assembly and the third shielding plate relative to the second shielding plate are adjusted according to the length of the base stone. After adjustment, the state of the flexible shielding plate is adjusted. Because the flexible shielding plate can undergo elastic deformation, it can fit against the side of the base stone closest to the asphalt pavement, preventing asphalt spray from contaminating the surface of the base stone and the base stone. Since the first shielding plate is used to cover the surface of the base stone, and the second shielding assembly is used to cover the base stone and the side of the base stone closest to the base stone, the support frame assembly can be easily erected on the base stone, facilitating installation and rapid laying, thus improving work efficiency.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figures 1 to 7As shown, a shielding device for preventing contamination of the standing stones during asphalt spraying, capable of shielding the standing stones 101 and 102, includes: a support frame assembly 1, the support frame assembly 1 being mounted on the standing stone 102, and a first shielding plate 2 being provided on the top of the support frame assembly 1; a second shielding assembly 3 being provided on the side of the support frame assembly 1 adjacent to the standing stone 101, capable of rotating relative to it; the second shielding assembly 3 including a second shielding plate 31 rotatably connected to the top of the support frame assembly 1; a third shielding plate 32 being connected to the second shielding plate 31, capable of rotating relative to it; a flexible shielding plate 33 being connected to the lower end of the third shielding plate 32; the flexible shielding plate 33 being deformable, so that part of the flexible shielding plate 33 can adhere to the standing stone 101; and a shielding space 34 is formed between the flexible shielding plate 33, the third shielding plate 32, and the second shielding plate 31, capable of shielding the side of the standing stone 102 adjacent to the standing stone 101.

[0026] In use, the support frame assembly 1 is placed on the base stone 102. At this time, the first shielding plate 2 covers the top surface of the base stone 102. Then, the angle of the second shielding plate 31 relative to the support frame assembly 1 and the angle of the third shielding plate 32 relative to the second shielding plate 31 are adjusted according to the length of the base stone 101. After adjustment, the state of the flexible shielding plate 33 is adjusted. Since the flexible shielding plate 33 can produce elastic deformation, it can fit against the side of the base stone 101 near the asphalt pavement, preventing asphalt spraying from contaminating the surface of the base stone and the base stone. Since the first shielding plate 2 is used to cover the surface of the base stone, and the second shielding assembly 3 is used to cover the base stone and the side of the base stone near the base stone, the support frame assembly 1 can be easily placed on the base stone, facilitating installation and rapid laying, and improving work efficiency.

[0027] The support frame assembly 1 includes multiple support brackets 11 arranged front to back. Each support bracket 11 is provided with a slot 111 for inserting a stepping stone. A connecting bracket 12 is provided between two adjacent support brackets 11. A connecting component 13 is provided between the connecting bracket 12 and the two support brackets 11 to connect and fix the three together. The first baffle plate 2 is connected to the connecting bracket 12. The slots 111 allow each support bracket 11 to be precisely inserted into the stepping stone 102, ensuring a tight connection between the device and the stepping stone 102. Adjacent support brackets 11 are fixed together by the connecting bracket 12 and the connecting component 13, forming a stable support.

[0028] The support bracket 11 includes two spaced-apart support rods 112, each L-shaped, with multiple cross braces 113 connecting them. A connecting rod 114 connects the two cross braces 113, and a slot 111 is formed between the two support rods 112. This design of the support bracket 11, with the slot 111 formed by the two spaced-apart L-shaped support rods 112, securely holds the support stone 102. The multiple cross braces 113 and connecting rods 114 further enhance the overall strength and stability of the support bracket 11, resulting in better support.

[0029] The connecting assembly 13 includes a first connecting seat 131 connected to the support rod 112, the first connecting seat 131 having a first connecting hole 1311. A protruding second connecting seat 132 is provided on the side wall of the connecting bracket 12, the second connecting seat 132 having a second connecting hole 1321. The first connecting hole 1311 and the second connecting hole 1321 on the same side are on the same axis. The connecting assembly 13 also includes a connecting rod 133 capable of simultaneously passing through both the first connecting hole 1311 and the second connecting hole 1321 to connect and fix the first connecting seat 131 and the second connecting seat 132. Through the cooperation of the first connecting hole 1311 on the first connecting seat 131, the second connecting hole 1321 on the second connecting seat 132, and the connecting rod 133, a quick and stable connection between the support bracket 11 and the connecting bracket 12 is achieved. This connection method is not only easy to install and disassemble, which can significantly improve construction efficiency, but also, through the fixing effect of the connecting rod 133, the connecting rod 133 can also be used to connect the second baffle 31, which enhances the support strength of the support bracket 11 and the connecting bracket 12.

[0030] A hinge 4 is provided between the flexible shielding plate 33 and the third shielding plate 32 so that the flexible shielding plate 33 and the third shielding plate 32 can be rotatably connected, which facilitates the connection. Moreover, the hinge 4 is low in cost and easy to replace if damaged.

[0031] The second shielding plate 31 includes an arc-shaped second frame body 311, on which a second plate 312 is connected. A second support rod 313, which can connect to the second plate 312, is also provided in the middle of the second frame body 311. The overall frame structure facilitates welding, and the second support rod 313 further enhances the structural strength and stability of the second plate 312.

[0032] The third shielding plate 32 includes a third frame body 321, one end of which is rotatably connected to the second frame body 311. A third plate 322 is provided on the back side of the third frame body 321, and a third support rod 323 is also provided in the middle of the third frame body 321. The overall frame structure facilitates welding, and the third support rod 323 further enhances the structural strength and stability of the second plate 312. The third support rod 323 is H-shaped and also includes a crossbar to improve structural strength.

[0033] The flexible shielding plate 33 includes a flexible shielding plate body 331 capable of deformation. The top front and rear sides of the flexible shielding plate body 331 are provided with a first clamping plate 332 and a second clamping plate 333 capable of clamping it. The first clamping plate 332, the flexible shielding plate body 331 and the second clamping plate 333 are connected and fixed to the hinge 4 by screws.

[0034] The flexible shielding plate body 331 can deform to closely conform to the shape of the stone 101, thereby effectively preventing asphalt from contaminating the surface of the stone. The first clamping plate 332 and the second clamping plate 333 clamp and fix the flexible shielding plate body 331, and fix it to the hinge 4 by screws, which facilitates installation and also makes it easy to replace if damaged.

[0035] The first shielding plate 2 is provided with an outwardly extending baffle 21. The outwardly extending baffle 21 provided on the first shielding plate 2 can further expand the shielding range and effectively prevent asphalt from splashing from the edge of the base stone 102 to the surrounding area when spraying, thus enhancing the shielding effect.

[0036] The first shielding plate 2 is provided with a protruding locking plate 22, which forms a locking groove 221 into which the connecting bracket 12 can be engaged. The locking groove 221 can be tightly engaged with the connecting bracket 12, realizing a stable connection between the first shielding plate 2 and the support frame assembly 1. This connection method allows for fast installation and easy disassembly, improving construction efficiency.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
