Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a tack oil spraying and shielding device. Background Art

[0002] Tack coat oil is a bonding agent specially used in asphalt road construction. During asphalt road construction, a layer of cement roadbed is first laid, and then asphalt is laid on the cement roadbed. Tack coat oil is usually sprayed between the asphalt layer and the cement layer to ensure that the asphalt layer and the cement layer are connected as a whole, thereby improving the quality and stability of the asphalt road.

[0003] After searching, a Chinese patent with announcement number CN213836167U discloses a tack coat oil spraying device, which is used to solve the technical problem mentioned in the background technology that it is difficult to clean up the scattered gravel on the road surface by only using a fan, thereby affecting the quality of tack coat oil spraying. The device includes a movable base plate and a tack coat oil spreader arranged on the base plate. A pull-out plate that can be pulled horizontally and extended out of the base plate is passed through the base plate. A mounting plate is fixed to the outer end of the pull-out plate. The bottom end of the mounting plate is rotatably connected to a strip-shaped connecting plate. The connecting plate can swing horizontally. An elastic scraper is detachably installed at the bottom of the connecting plate and along the length direction of the connecting plate. The utility model has a simple structure and is easy to use. It is mainly used for tack coat oil spraying operations.

[0004] However, in the above technical solution, only the tack coat oil spreader can be used to spray the tack coat oil on the road surface between the mounting plate and the base plate. However, when spreading the tack coat oil, since the nozzle sprays in a fan shape, it is easy to cause pollution when it is close to the markings, water retaining strips, bridge guardrail bases and other locations, especially the markings. Once contaminated, it affects the reflective effect and easily causes accidents when vehicles pass at night. Utility Model Content

When the area of ​​the shielding end increases, the shielding effect of the tack coat oil sprayed by the spray head 2 will be enhanced, so as to prevent the tack coat oil from being sprayed too widely and polluting surrounding markings and other objects.

[0022] Example 2

[0023] like Figure 2-Figure 4 As shown, the present invention proposes a device for shielding the spraying of tack oil. Compared with the first embodiment, the present embodiment describes the detailed structure of the shielding assembly. The shielding assembly includes a support plate 3, a mounting plate 4, a protective pad 5 and an extension assembly. Two support plates 3 are symmetrically provided and can be detachably connected to the spraying bracket 1.

[0024] In an optional embodiment, the support plate 3 is connected to symmetrically arranged limit plates 13, and a threaded rod 14 is threadedly connected to any limit plate 13. The end of the threaded rod 14 away from the limit plate 13 is connected to an adjustment handle 15, and the end of the threaded rod 14 close to the limit plate 13 is rotatably connected to a clamping plate 16;

[0025] In an optional embodiment, a positioning column 17 is connected to the clamping plate 16; the positioning column 17 can be inserted into the blind hole opened on the spray bracket 1 to position the clamping plate 16 and the support plate 3

[0026] The mounting plates 4 are connected to the support plates 3, and the number of mounting plates 4 corresponds to the number of support plates 3;

[0027] In an optional embodiment, the mounting plate 4 is composed of a fixed plate 6 and a movable plate 7, the fixed plate 6 is connected to the support plate 3, and a receiving groove is provided on the fixed plate 6, and the movable plate 7 is slidably connected in the receiving groove;

[0028] The protective pad 5 is bonded to the opposite side of the mounting plate 4; the protective pad 5 is selected from but not limited to a rubber layer;

[0029] The expansion assembly is connected to the mounting plate 4; when the expansion assembly is in use, the telescopic end of the expansion assembly pushes the mounting plate 4 to cause it to deform;

[0030] The expansion assembly includes a guide rod 8, an elastic member 9 and a connecting plate 10. A plurality of guide rods 8 are evenly spaced along the length of the movable plate 7. One end of the guide rod 8 is connected to the movable plate 7, and the other end of the guide rod 8 passes through the through holes opened on the fixed plate 6 and the support plate 3 to connect to the limit block; the number of elastic members 9 corresponds to that of the guide rods 8, and the elastic member 9 is the telescopic end of the expansion assembly, and the elastic member 9 is sleeved on the outside of the guide rod 8; the elastic member 9 can be selected from but not limited to a spring; the connecting plate 10 is connected to the end of the movable plate 7 away from the fixed plate 6, and a plurality of rollers are installed on the connecting plate 10; when the rollers are in contact with the ground, the connecting plate 10 and the movable plate 7 are both at a certain distance from the ground;

[0031] In an optional embodiment, a baffle 11 is connected to the movable plate 7, and a guide plate 12 is connected to the baffle 11; the guide plate 12 and the baffle 11 are spliced ​​into a triangular structure, and the angle of the guide plate 12 pushes debris on the road surface to both sides to prevent it from affecting the spraying effect.

[0032] In summary, when the present invention is used, the worker connects the spray bracket 1 with the construction vehicle, and then moves the support plate 3 close to the spray bracket 1. The rotating adjustment handle 15 will drive the threaded rod 14 to rotate synchronously. The rotation of the threaded rod 14 drives the clamping plate 16 close to the other limit plate 13. The spray bracket 1 is clamped by changing the distance between the two. The position of the clamping plate 16 is limited by the cooperation of the positioning column 17 connected to the clamping plate 16 and the blind hole on the spray bracket 1. When the spray head 2 on the spray bracket 1 sprays the tack coat oil, the movement of the construction vehicle will drive the spray bracket 1 to move synchronously, and the deflector on the spray bracket 1 12 and the baffle 11 will be close to the ground to remove large pieces of sand and debris that may affect the spraying quality on the ground, and the shape of the guide plate 12 will guide the debris to both sides to prevent it from accumulating in front of the guide plate 12. When moving, the rollers on the connecting plate 10 are in contact with the ground, and the elastic member 9 pushes the movable plate 7 and the connecting plate 10 close to the ground through its own elastic force, increasing the range that can be covered by the mounting plate 4 and the protective pad 5, avoiding gaps in the cover. When the movable plate 7 moves, it slides in the through hole on the support plate 3 through the guide rod 8 connected to its top to guide it, and the limit block on the guide rod 8 can limit its range of movement.
