Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and specifically to a spray anti-overflow device for road construction. Background Technology

[0002] Road construction includes laying asphalt. To improve the road's aesthetics and slow down the asphalt's fading rate, a color-changing process is required on the asphalt surface. This involves workers using spray guns to apply a color-changing coating to the asphalt surface. During spraying, to prevent color bleeding at the edges, baffles are erected at the edges of the target area to block the coating from spilling out.

[0003] During the spraying process, the worker holding the spray gun needs to move along the direction of the target area, and the baffle also needs to move with the position of the spray gun in order to cover the entire target area with paint. The baffle is mainly set up by the worker holding the baffle. Therefore, when moving the baffle, the worker mainly moves the baffle to change its position, which is somewhat inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spray anti-overflow device for road construction, which can facilitate the movement of the baffle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray anti-overflow device for road construction, comprising a frame, with wheels on both sides of the frame, symmetrical support rods at the front end of the frame, a connecting rod between the two support rods, a handle at the top of the frame, the handle having two ends serving as connecting ends and gripping ends, the connecting end being rotatable around the support rod, a horizontally arranged connecting rod on the outer side of the connecting end, a sleeve at the end of the connecting rod, a guide rod at the front end of the frame, the sleeve being fitted around the outer periphery of the guide rod, a baffle on the outer side of the sleeve, the sleeve rotating around the support rod via the connecting end and sliding along the guide rod to drive the baffle to rise and fall.

[0006] The present invention is further configured such that: a connecting pipe is provided on the outer periphery of the connecting end, and the connecting pipe is fitted onto the outer periphery of the support rod.

[0007] The present invention is further configured such that: a connecting tube is fitted around the outer periphery of the connecting rod, a connecting flange extending outward is provided around the outer periphery of the connecting tube, an installation tube is fitted around the end of the connecting end, and the connecting flange is rotatably connected to the installation tube.

[0008] The present invention is further configured such that: the outer periphery of the sleeve is provided with an outwardly extending extension rod, the end of the extension rod located away from the sleeve is provided with an installation rod, the two ends of the installation rod serve as extension ends, the two side extension ends extend to the sides respectively, and the baffle can slide on the two side extension ends respectively to adjust the distance between adjacent baffles.

[0009] The present invention is further configured such that: the baffle is provided with a through hole, the outer periphery of the through hole is provided with a sleeve, the extension end is provided with a first pin hole spaced axially, the sleeve is provided with a second pin hole through, and the second pin hole is opposite to the first pin hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The frame can support the baffle. After the frame is pushed, the wheels can roll, making it easy to adjust the position of the baffle. When it is necessary to move the baffle, it can be lifted off the ground to avoid friction caused by the baffle contacting the ground. This makes it easier to move the frame and further facilitates the adjustment of the baffle's position. Attached Figure Description

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] like Figures 1 to 3 As shown, this utility model discloses a spray anti-overflow device for road construction, including a frame 1, with wheels 2 on both sides of the frame 1. The frame 1 can support the baffle 9 described below. After pushing the frame 1, the wheels 2 can roll, thereby conveniently adjusting the position of the baffle 9.

[0018] Specifically, a symmetrical support rod 3 is provided at the front end of the frame 1. The support rod 3 is fixed to the frame 1 by welding. A connecting rod 4 is fixed between the two support rods 3 by welding. A handle 5 is provided on the top of the frame 1. The two ends of the handle 5 serve as connecting ends 51 and gripping ends 52. The gripping ends 52 are used for workers to grip and apply horizontal force to the frame 1, thereby facilitating the movement of the frame 1. The connecting ends 51 can rotate around the support rod 3. A horizontally arranged connecting rod 6 is provided on the outer side of the connecting ends 51. A sleeve 7 is provided at the end of the connecting rod 6. A guide rod 8 is provided at the front end of the frame 1. The sleeve 7 is fitted around the outer periphery of the guide rod 8. A baffle 9 is provided on the outer side of the sleeve 7. The connecting end 51 rotates around the support rod 3 and slides along the guide rod 8 to drive the baffle 9 to rise and fall. When it is necessary to move the baffle 9, pressing down the handle 5 will lift the baffle 9 off the road surface, thus avoiding the friction caused by the baffle 9 contacting the road surface. This makes it easier to move the frame 1 and adjust the position of the baffle 9. After the baffle 9 is moved to the target position, releasing the handle 5 will cause the handle 5 to return to its original position under the influence of gravity at the connecting end 51, so that the baffle 9 will fall and re-contact the ground. This will block the paint sprayed on the target area during subsequent spraying operations.

[0019] In this embodiment, the specific structure of the baffle 9 that moves up and down with the handle 5 rotating around the support rod 3 is as follows: a connecting pipe 10 is welded to the outer periphery of the connecting end 51. The connecting pipe 10 is fitted around the outer periphery of the support rod 3, which can provide a fulcrum for the handle 5. By rotating the connecting pipe 10 around the support rod 3, the handle 5 can rotate around the support rod 3.

[0020] In addition, a connecting tube 11 is fitted around the outer periphery of the connecting rod 6. The connecting tube 11 has an outwardly extending connecting flange 111 on its outer periphery. An installation tube 12 is fitted and fixed to the end of the connecting end 51. The connecting flange 111 is rotatably connected to the installation tube 12 by a pin. Thus, through the connection of the connecting flange 111 and the installation tube 12, power can be transmitted when the handle 5 is pressed down, forming a lever structure. After the handle 5 is pressed down, the sleeve 7 can be driven to slide upward along the guide rod 8, causing the bottom of the baffle 9 to lift off the ground.

[0021] In this embodiment, an outwardly extending extension rod 13 is welded and fixed to the outer periphery of the sleeve 7. An installation rod 14 is welded and fixed to the end of the extension rod 13 on the side away from the sleeve 7. The two ends of the installation rod 14 serve as extension ends, and the two extension ends extend to both sides respectively. In this way, the baffle 9 can slide on the two extension ends respectively to adjust the distance between adjacent baffles 9, thereby adapting to a wider road surface and improving the flexibility of application.

[0022] In addition, the baffle 9 is provided with a through hole, and a sleeve 91 is provided on the outer periphery of the sleeve hole. The extended end is provided with a first pin hole 141 that is axially spaced apart. The sleeve 91 is provided with a through second pin hole. The second pin hole can be opposite to the first pin hole 141. With the arrangement of the first pin hole 141 and the second pin hole, after the second pin hole on the sleeve 91 is slid to a position opposite to the first pin hole 141, a pin can be inserted into the first pin hole 141 and the second pin hole, thereby preventing the baffle 9 from moving erroneously.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
