Description

Technical Field

[0001] The utility model relates to the technical field of road engineering construction, in particular to a spray maintenance device for road construction. Background Technique

[0002] Concrete curing is to artificially create certain humidity and temperature conditions to enable the freshly poured concrete to harden normally or accelerate its hardening and strength growth. After laying concrete on the road, spray curing is required to prevent the concrete road from cracking and resulting in unqualified roads. Currently, the maintenance method is similar to that of a sprinkler truck. Specifically, workers stand on the vehicle and control the direction of the nozzle to achieve spray maintenance at different positions on the road surface. For a two-way narrow road, the rotation angle of the nozzle is small, and the workload of the staff is also small. However, when spray curing a wider tunnel road, the staff needs to rotate the nozzle at a large angle, and correspondingly, the vehicle speed needs to be reduced to ensure comprehensive spray maintenance, thus reducing the efficiency of spray maintenance. In addition, manually adjusting the steering of the nozzle, the spraying direction is parabolic, and the spraying amount in different directions cannot be effectively controlled, and the uniformity of the distribution of the water used for spray maintenance is poor. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: Referring to the attached drawings of the specification Figures 1-3 It can be seen that the present application specifically designs a spray maintenance device for road construction. One side of the rear support 2 of the sprinkler body 1 is connected with a fixed frame 3 through a height adjustment structure. Both sides of the fixed frame 3 are connected with a swing frame 4 through a rotation adjustment structure. Spray components are installed on both the fixed frame 3 and the swing frame 4. Among them, the water pump outlet pipeline 5 of the sprinkler body 1 is connected with the inlet end of a one-in-three-out joint 6, and the three outlet ends of the one-in-three-out joint 6 are respectively communicated with the spray components. The above spray components include a water distribution pipe 7, a spray head 8, a control valve 9, an electromagnetic flow valve 10 and a water guiding hose 11. The water distribution pipe 7 is arranged on the fixed frame 3. The spray heads 8 are installed on the lower side wall surface of the water distribution pipe 7 at fixed intervals. The control valve 9 is installed on the outlet end of the one-in-three-out joint 6. The electromagnetic flow valve 10 is installed on one side of the control valve 9. One end of the water guiding hose 11 is connected with the electromagnetic flow valve 10 and the other end is connected with the water distribution pipe 7. During use, according to the actual needs of spray maintenance operations, the height of the fixed frame 3 and the swing frame 4 can be adjusted by using the height adjustment structure, so as to adjust the height position of the spray components during the spray maintenance operation, thereby reducing the scouring force of the spray water on the road surface. At the same time, in cooperation with the rotation adjustment structure, the rotation adjustment of the swing frame 4 can be realized, and then the spray maintenance operation of roads with different widths can be realized. The structure is compact, the design is reasonable, and the degree of automation is relatively high, greatly reducing the labor intensity of workers. Moreover, the spray volume can be accurately controlled, reducing the cost of road spray maintenance operations. The spray volumes of different spray components can be adjusted separately to meet the spray maintenance needs of roads with different widths.

[0019] In the specific implementation process, the above-mentioned height adjustment structure includes a lead screw module 12 and a guiding and limiting member. The lead screw module 12 is arranged vertically on the tail bracket 2, and its moving end is connected to the fixed frame 3. The guiding and limiting members are symmetrically arranged on both sides of the lead screw module 12 and are slidably connected to the fixed frame 3. The guiding and limiting member includes a chute 13 and a guide rail 14. The chute 13 is fixed on the tail bracket 2 and is symmetrically arranged along the lead screw module 12. The guide rail 14 is welded to the side wall of the fixed frame 3 and is slidably matched with the chute 13. When it is necessary to adjust the working height of the spraying assembly, the lead screw module 12 is started, and the lead screw module 12 is used to drive the fixed frame 3 to slide in the vertical direction in cooperation with the guide rail 14 and the chute 13, thereby realizing the height adjustment of the fixed frame 3 and the swing frame 4, so that the spray head 8 is located at different height positions for spraying and curing operations.

[0020] In the specific implementation process, the above-mentioned rotation adjustment structure includes a fixed seat 15, a rotating shaft 16, a connecting seat 17 and a driving member. The fixed seat 15 is arranged on the side wall of the fixed frame 3. The rotating shaft 16 is rotatably inserted into the fixed seat 15. One end of the connecting seat 17 is in interference fit with the rotating shaft 16, and the other end is fixedly welded to the swing frame 4. The driving member is arranged on the fixed frame 3 and its output end is connected to the rotating shaft 16. The driving member includes a servo motor 18 and a speed reducer 19. The servo motor 18 is installed on the fixed frame 3, and the speed reducer 19 is installed on the fixed seat 15. The input end of the speed reducer 19 is connected to the driving end of the servo motor 18, and the output end is connected to the rotating shaft 16. A protective housing is buckled outside the above-mentioned servo motor 18. According to the width of the actual maintenance construction road surface, the position of the swing frame 4 is adjusted. That is, when the working road surface is relatively wide, the servo motor 18 on the fixed frame 3 is started, and the driving end of the servo motor 18 is controlled to rotate at a constant speed. Thus, under the cooperation of the speed reducer 19, the rotating shaft 16 rotates, and then drives the swing frame 4 at one end of the connecting seat 17 on the rotating shaft 16 to swing horizontally, expanding the working area of the spraying assembly. After the operation is completed, the swing frame 4 can be controlled to retract to both sides of the sprinkler body 1. The structure is compact, the operation is convenient, and the practicability is strong.
