Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, in particular to road maintenance equipment for municipal road construction. Background Art

[0002] Municipal roads need to be maintained after they are paved in order to maintain their original good condition and service level. Sprinkling water on the road surface is one of the maintenance items of municipal roads.

[0003] In the prior art, a Chinese patent with authorization announcement number CN216809476U discloses a road maintenance device for municipal road construction. The motor drives the turntable to rotate through the fixed rod 1 on the top of the turntable and the transmission connection with the fixed rod 2 with the straight groove and the connecting hole, which can make the swing frame swing and drive the pipe clamped by the pipe clamp on one side of the swing frame to swing left and right, thereby increasing the watering area. By rotating the adjustment handle on the top of the fixed plate, the adjustment handle drives the screw to rotate. The screw and the lifting plate are threadedly connected to adjust the height of the lifting plate, and then the height of the swing assembly on the lifting plate can be adjusted, which is convenient for maintaining road surfaces of different widths.

[0004] The above-mentioned existing technical solutions have the following defects: during the road maintenance process, the required amount of water for spraying will depend on factors such as the type of road, maintenance conditions and climate. The road maintenance device for municipal road construction can only adjust the watering area, and it is difficult to adjust the amount of water for spraying. At present, the function of adjusting the water volume is mostly completed through a faucet, and it is difficult to accurately control the water output. Excessive amount of water for spraying can easily lead to water accumulation in low-lying sections of the road. When there is a lot of mud on the road surface, it is easy to produce a muddy state, causing secondary pollution of the road surface. When the amount of water for spraying is too little, the maintenance effect cannot be reflected, which can easily cause cracking and collapse of the road surface, affecting the service effect and service life of the municipal road.

[0005] For this reason, a road maintenance equipment for municipal road construction is proposed. Utility Model Content

[0026] like Figures 1 to 5 As shown, a road maintenance equipment for municipal road construction includes a cart 1, a water tank 2 is fixedly installed on the top surface of the cart 1, a water pump 3 is fixedly installed on the top surface of the water tank 2, a water flow regulating valve 4 is fixedly installed on the top surface of the water pump 3, a distance adjusting mechanism 5 is provided on the top surface of the inner wall of the water flow regulating valve 4, an outlet regulating mechanism 6 and an elastic telescopic water retaining assembly 7 are provided on the inner wall of the water flow regulating valve 4, a lifting mechanism 8 is provided on the front side of the water tank 2, a lateral moving mechanism 9 is provided on the surface of the lifting mechanism 8, a water pipe 10 is fixedly connected to the surface of the water flow regulating valve 4, the water pipe 10 is communicated with the inside of the water flow regulating valve 4, a spray head 11 is fixedly installed on the surface of the lateral moving mechanism 9, and the inside of the spray head 11 is communicated with the water pipe 10.

[0027] Specifically, when maintaining the road surface, the road maintenance equipment is moved by the mobile cart 1 to maintain the road surface at different positions. During the maintenance process, the water in the water tank 2 is pumped into the water flow regulating valve 4 by the water pump 3, and then the water outlet regulating mechanism 6 is driven to move backward step by step by different distances through the distance adjustment mechanism 5 inside the water flow regulating valve 4, driving the elastic telescopic water retaining component 7 to undergo different degrees of elastic changes, thereby generating water outlet holes of different sizes, and finally the water output can be adjusted step by step from small to large. At the moment when the water outlet regulating mechanism 6 is reset by the distance adjustment mechanism 5, the elasticity of the elastic telescopic water retaining component 7 itself is utilized to restore the elastic telescopic water retaining component 7. Deformation is realized to close the water flow regulating valve 4. In this process, the function of reducing the water output can also be realized, thereby realizing precise adjustment of the water output size, which is beneficial to enhancing the effect of road maintenance and extending the service life of municipal roads. The water after adjusting the water volume enters the spray head 11 through the water pipe 10 to spray the road surface for maintenance. The lifting mechanism 8 and the lateral moving mechanism 9 arranged on the front of the water tank 2 can be structures with moving functions such as threaded rods or electric push rods. The lifting mechanism 8 and the lateral moving mechanism 9 are used to drive the spray head 11 to move up and down and left and right, which is convenient for spraying roads of different widths, increases the spraying area, and improves work efficiency.

[0028] like Figures 1 to 5 As shown, the water flow regulating valve 4 includes a regulating valve body 401 , a water inlet 402 is provided on the bottom surface of the regulating valve body 401 , a water outlet 403 is provided on the side surface of the regulating valve body 401 , and the surface of the water outlet 403 is fixedly connected to the water pipe 10 .

[0029] Specifically, the water pump 3 draws the water in the water tank 2 into the regulating valve body 401 through the water inlet 402, and after adjusting the water volume, enters the water pipe 10 through the water outlet 403, so as to facilitate the water in the water tank 2 to be transported to the sprinkler head 11 for spraying.

[0030] like Figures 1 to 5 As shown, the distance adjustment mechanism 5 includes a slide groove 504, which is opened on the top surface of the inner wall of the water flow regulating valve 4. A threaded rod 502 is rotatably installed on the inner wall surface of the slide groove 504, and a knob 501 is fixedly installed on one end of the threaded rod 502. The knob 501 is arranged on the outside of the water flow regulating valve 4. A sliding rod 503 is threadedly sleeved on the surface of the threaded rod 502. The sliding rod 503 is slidably installed on the inner wall surface of the slide groove 504, and the water outlet adjustment mechanism 6 is fixedly installed on the surface of the sliding rod 503.

[0031] Specifically, by rotating the knob 501, the threaded rod 502 is driven to rotate, thereby driving the sliding rod 503, which is threadedly sleeved on the surface of the threaded rod 502 and slidably installed on the inner wall surface of the sliding groove 504, to move forward and backward, thereby driving the water outlet adjustment mechanism 6 on the surface of the sliding rod 503 to move forward and backward. By adjusting the position of the water outlet adjustment mechanism 6, the water output can be adjusted conveniently.

[0032] like Figures 1 to 5 As shown, the elastic telescopic water retaining assembly 7 includes a sleeve rod 701, which is fixedly installed on the inner wall surface of the water flow regulating valve 4. A spring 702 is fixedly installed on the left inner wall surface of the sleeve rod 701, and a slider 704 is fixedly installed on the other end of the spring 702. A push rod 703 is fixedly installed on the side surface of the slider 704 away from the spring 702. The push rod 703 is slidably inserted into the surface of the sleeve rod 701, and a baffle 705 is fixedly installed on the end surface of the push rod 703 away from the sleeve rod 701. There are four baffles 705, and the four baffles 705 are arranged in a concentric ring-shaped nested sliding installation. The outermost baffle 705 is arranged to slide against the side of the inner wall of the water outlet 403.

[0033] Specifically, when the baffle 705 moves backward, the push rod 703 is acted upon by the force to drive the slider 704 to slide on the inner wall surface of the sleeve rod 701, and at the same time, the spring 702 is compressed by the squeezing force. When the baffle 705 moves forward, under the action of the elastic restoring force of the spring 702, the slider 704 slides on the inner wall surface of the sleeve rod 701, pushing the push rod 703 and the baffle 705 forward, so that the baffle 705 is reset, thereby achieving precise adjustment of the water output.

[0034] like Figures 1 to 5 As shown, the water outlet regulating mechanism 6 includes a connecting rod 601, one end of the connecting rod 601 is fixedly installed on the surface of the sliding rod 503, a limiting plate 604 is fixedly installed on the surface of the end of the connecting rod 601 away from the sliding rod 503, the number of the limiting plates 604 is four and they are installed at intervals from front to back, the center baffle plate 705 is slidably installed on the surface of the connecting rod 601, and a positioning plate 603 is radially fixedly installed on the inner wall side of the water outlet 403, and the positioning plate 603 is arranged to fit the surface of the baffle plate 705.

[0035] Specifically, the connecting rod 601 is driven to move forward and backward by the forward and backward movement of the sliding rod 503, thereby driving the limit plate 604 fixedly installed on the surface of the connecting rod 601 to move. The limit plate 604 moves backward by different distances to drive baffles 705 of different specifications to slide from the water outlet 403 toward the regulating valve body 401. Adjacent baffles 705 are staggered with each other, so that water can flow out from the staggered gaps. By driving the baffles 705 to move, different numbers of staggered gaps are generated, thereby providing water discharge channels of different sizes, so that the water output can be accurately adjusted. Under the action of the elastic restoring force of the spring 702, the sliding block 704 slides on the inner wall surface of the sleeve rod 701, pushing the push rod 703 and the baffle 705 forward until they are close to the positioning plate 603 to facilitate the limiting of the baffle 705, thereby achieving accurate blocking of the water outlet 403 and preventing water leakage.

[0036] like Figures 1 to 5As shown, the size of the limiting plates 604 gradually decreases from front to back, and the width of each limiting plate 604 is between the inner and outer ring diameters of the corresponding baffle 705 .

[0037] Specifically, the size of the limit plate 604 gradually decreases from front to back to facilitate pushing of baffles 705 of different sizes. The width of each limit plate 604 is between the inner and outer ring diameters of the corresponding baffle 705, so that each baffle 705 can slide independently without being affected by each other, which is conducive to precise adjustment of the water output.

[0038] In summary: When the utility model is maintaining the road surface, the water in the water tank 2 is pumped into the water flow regulating valve 4 through the water pump 3, and then the distance adjustment mechanism 5 inside the water flow regulating valve 4 drives the water outlet regulating mechanism 6 to move backward step by step to different distances, driving the elastic telescopic water retaining component 7 to undergo different degrees of elastic changes, thereby generating water outlet holes of different sizes, and finally the water output can be adjusted step by step from small to large. At the moment when the water outlet regulating mechanism 6 is reset by the distance adjustment mechanism 5, the elastic telescopic water retaining component 7 restores its deformation to achieve the closure of the water flow regulating valve 4. In this process, the function of reducing the water output can also be achieved, thereby achieving precise adjustment of the water output, which is beneficial to enhancing the effect of road maintenance and extending the service life of municipal roads.
