Description

Technical Field

[0001] This utility model relates to the field of highway spraying technology, and in particular to a spraying membrane device for highway construction. Background Technology

[0002] During highway construction, a film can be formed on the road surface by spraying to achieve the corresponding maintenance function. For example, during the construction of cement concrete pavement, water can be sprayed to cure the concrete during the concrete setting process to prevent subsequent cracking. When converting old pavement into asphalt pavement, tack coat oil can also be sprayed on the old pavement by spraying a film to facilitate the connection between the new surface layer and the original pavement.

[0003] Currently, when using spray membrane devices, the spraying mechanism is mostly fixedly installed on the equipment and does not have the function of adaptive angle adjustment. When the mobile device is spraying membrane on the road surface, when the road surface has a slope, the device will tilt at a certain angle with the undulation of the road surface, and at the same time, it will cause the spraying mechanism to tilt, so that the spraying coverage area changes with the angle, affecting the single-point spraying volume on the road surface, and thus reducing the spraying quality.

[0004] Therefore, it is necessary to provide a spray membrane device for highway construction to solve the above-mentioned technical problems. Utility Model Content

This ensures that the nozzle is always perpendicular to the road surface during spraying, solving the problem that the device will tilt at a certain angle due to the undulation of the road surface, causing the spraying mechanism to tilt as well, which in turn changes the spraying coverage area with the angle, affecting the single-point spraying volume on the road surface and thus reducing the spraying quality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-4 This utility model provides a spraying membrane device for highway construction: It includes a base 1, with a storage box 2 and a connecting frame 3 fixedly connected to the top of the base 1. The connecting frame 3 has two rotating grooves 4, each containing a rotating ball 5. A connecting rod 6 is fixedly connected to the outer surface of each rotating ball 5. A support plate 7 is fixedly connected to the bottom of the connecting rod 6. Two sliding grooves 17 are formed at the bottom of the support plate 7, each containing an adjusting block 18. A spraying pipe 8 is fixedly connected to the bottom of the support plate 7. Several nozzles 9 are mounted on the spraying pipe 8, and two pistons 10 are mounted inside the spraying pipe 8, with the pistons 10 interlocking with the inner wall of the spraying pipe 8. The device is adapted to the following configuration: the base 1 is equipped with a conveying component, a buffer component, and four casters 11; the support plate 7 is equipped with an adjustment component one and an adjustment component two. Through the coordinated use of the base 1, storage box 2, connecting frame 3, rotating groove 4, rotating ball 5, connecting rod 6, spray pipe 8, nozzle 9, casters 11, and pump body 12, the spray pipe 8 and nozzle 9 can adaptively adjust their angles when the device moves to perform spraying work. This ensures that the nozzle 9 is always perpendicular to the road surface for spraying work, solving the problem that the device will tilt at a certain angle due to the undulation of the road surface, which will cause the spraying mechanism to tilt, resulting in changes in the spray coverage area with the angle, affecting the single-point spray volume on the road surface, and thus reducing the spraying quality.

[0032] The delivery assembly includes a pump body 12 fixedly installed on the top of the base 1. The input end of the pump body 12 is fixedly connected to the storage tank 2, and the output end of the pump body 12 is fixedly connected to the spray pipe 8 through the hose 13. Through the setting of the delivery assembly, the liquid inside the storage tank 2 can be delivered to the inside of the spray pipe 8 and sprayed out by the nozzle 9 to carry out the spraying and film covering work.

[0033] The buffer assembly includes four dampers 14 fixedly connected to the bottom of the base 1. Each of the four dampers 14 has a mounting plate 15 fixedly connected to its bottom. A caster wheel 11 is fixedly connected to the bottom of the mounting plate 15. A spring 16 is fitted on the outer surface of the damper 14. By setting up the buffer assembly, the vibration caused by uneven road surface during the movement of the device can be reduced, thereby improving the stability of the device during use.

[0034] The first adjustment assembly includes two connecting plates 19, which are fixedly connected to one side of two adjusting blocks 18. Both connecting plates 19 are threaded with external threaded sleeves 20, and an elastic telescopic rod 21 is fixedly connected inside the external threaded sleeve 20. The elastic telescopic rod 21 is square in shape, and one end of the elastic telescopic rod 21 is fixedly connected to one side of the piston 10. By setting the first adjustment assembly, the position of the piston 10 can be adjusted individually, so that the piston 10 can be moved to different positions for use, thereby improving the practicality of the device.

[0035] The second adjustment component includes a bidirectional threaded rod 22, which is rotatably connected to the support plate 7. The bidirectional threaded rod 22 is threadedly connected to two adjustment blocks 18. By setting the second adjustment component, the positions of the two pistons 10 can be adjusted simultaneously, thereby improving the adjustment efficiency of the pistons 10.

[0036] Working principle: During operation, add an appropriate amount of liquid into the storage tank 2, then move the device to the usage position. Then, depending on the device's position on the road surface, adjust the number of nozzles 9 on one side or both sides simultaneously according to the road area to be sprayed. That is, manually rotate one side of the elastic telescopic rod 21, which drives the external threaded sleeve 20 to rotate synchronously. With the cooperation of the corresponding threaded connecting plate 19, the elastic telescopic rod 21 drives the corresponding piston 10 to move inside the spray pipe 8, which can block or unblock the nozzles 9 on one side of the spray pipe 8 and adjust the number of nozzles 9 used. When manually rotating the bidirectional threaded rod 22, under the guide limit of the slide groove 17, the two adjusting blocks 18 drive the corresponding adjusting plates, external threaded sleeves 20, elastic telescopic rods 21 and pistons 10 to move apart or relative to each other, which can simultaneously adjust the number of nozzles 9 used on both sides of the spray pipe 8, so that the device can spray the film simultaneously according to the width of the road surface when in use.

[0037] After adjusting the number of nozzles 9, the device is moved by the casters 11 and the pump 12 is started. The liquid added in the storage tank 2 is transported to the spray pipe 8 through the hose 13 and then sprayed out by the adjusted nozzles 9 to carry out the spraying work. At the same time, when the road surface has a slope and the device has a certain tilt and undulation when it moves, the rotating ball 5 is automatically rotated and adjusted by the gravity of the support plate 7, the bidirectional threaded rod 22 and the spray pipe 8, so that the nozzles 9 are all vertically facing the road surface to prevent the spraying area from changing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
