Description

Technical Field

[0001] The invention belongs to the technical field of municipal engineering construction, and in particular relates to a spray maintenance device for municipal engineering construction. Background Art

[0002] The construction of various public infrastructure supporting urban life falls into the category of municipal engineering. Among them, common urban roads, bridges, subways, various pipelines closely related to life, squares, urban greening, etc., all fall into the category of municipal engineering. In the construction process of urban roads, in order to avoid cracking after road grouting, corresponding equipment is needed to carry out spray maintenance on this section of road in the subsequent maintenance.

[0003] However, in the current road construction of municipal engineering, in order to prevent the road surface from drying out during construction, a water pipe connected to multiple nozzles will be set at the location of the construction road at that end. Although its structure is simple and low in cost, or a mobile spraying device is directly used to spray the road surface, the spraying maintenance equipment composed of multiple nozzles is not easy to carry. At the same time, the combination of multiple nozzles and mobile spraying equipment cannot achieve equal-length spraying of the construction section. There is a situation where the spraying range is exceeded, and when spraying, there are problems of different spraying degrees at multiple different points. At the same time, when using mobile spraying equipment to spray and maintain the construction road surface, most of them are pushed manually to spray the road surface. However, this spraying maintenance method cannot spray both sides of the equipment synchronously, which will reduce the efficiency of spraying. At the same time, due to the use of mobile type, during the spraying process, it is easy for the moving route to have a position deviation, resulting in the spraying range being exceeded, reducing the utilization rate of water resources. Therefore, at present. To this end, we provide a spraying maintenance device for municipal engineering construction to solve the above problems. Summary of the invention

[0014] The concentrating pipe is connected to the end surface of the slider by bolts.

[0015] The present invention is further configured such that vertical rods are fixed to the left and right parts of the lower end surface of the slide bar, and the lower end surface of the vertical rods is fixedly connected to the upper end surface of the bottom plate.

[0021] When the slider moves, it pushes the rubber rod to move along the side of the slide bar, and then the rubber rod pushes or pulls another slider connected to it to move, so that the two sliders move in relative or opposite directions, thereby fully spraying the construction road surface on both sides of the device.

[0022] After the base plate is set on the road surface, when the base plate deviates to one side, it will drive the friction strip to move with it, so that the friction strip drives the tooth plate to rotate, and thereby controls the other friction strip symmetrically set to slide in the opposite direction. Therefore, through the opposite pulling of the two friction strips, the friction between the base plate and the road surface is increased, the gripping ability of the base plate is improved, the deviation of the base plate is avoided, and the spray maintenance range is prevented from being exceeded too much, thereby improving the utilization rate of water resources.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0038] See also Figure 1 , Figure 2 , Figure 5 and Figure 7 , which is the first embodiment of the present invention, provides a spray maintenance device for municipal engineering construction, through the repulsion between the eight-shaped electromagnet 203 and the magnetic plate 104, spraying treatment is achieved along the road, and at the same time, the rubber soft rod 202 links the two sliders 201 to achieve comprehensive spraying treatment of the construction road surface on both sides of the device, and the tooth plate 402 drives the two friction strips 401b to move alternately, which can improve the stability of the entire device.

[0039] Specifically, the driving assembly 100 includes two slide bars 101 symmetrically arranged front and back, a bottom plate 102 located directly below the two slide bars 101, and two convex plates 105 symmetrically fixed on the upper end surface of the bottom plate 102; the sliding assembly 200 includes two sliders 201 respectively connected to the end surfaces of the slide bars 101 and a rubber soft rod 202 located between the two slide bars 101; the spray assembly 300 includes a water tank 301 located at the upper end surface of the bottom plate 102, an elastic curved water pipe 302 fixed at the water outlet position of the two water tanks 301, and a central pipe 303 located at the opposite end surface position of the two sliders 201; the linkage assembly 400 includes linkage bars 401 respectively sliding in the internal position of the moving bayonet 105a-2 and a tooth plate 402 rotatably arranged in the internal position of the linkage port 105c;

[0040] Through the arrangement and use of the above-mentioned structure, the two elastically curved water pipes 302 are connected to the water pump port position inside the water tank 301. Therefore, when performing spraying treatment, the water pump inside the water tank 301 can be controlled to work, so that the water pump draws the liquid inside the water tank 301 into the central box, thereby spraying the liquid to perform spraying maintenance on the roads on both sides of the device. At the same time, the tooth plate 402 drives the linkage bar 401 to rotate, so that the two adjacent linkage bars 401 will move in opposite or relative directions, thereby ensuring the stability of the position of the entire base plate 102.

[0041] according to Figure 4 , Figure 6 , Fig. 9 and Fig.10 , a magnetic plate 104 is fixed on the inner wall of the recessed openings on the opposite end faces of the two slide bars 101, two symmetrically arranged transverse openings 105a are provided on the lower end face of the convex plate 105, a through opening 105a-1 is provided on the top face inside the transverse opening 105a, a movable bayonet 105a-2 is provided on the upper end face of the through opening 105a-1, and a linkage opening 105c connected to the inside of the movable bayonet 105a-2 is provided inside each convex plate 105, and the two slide bars 201 are opposite to each other. The end faces are provided with two splayed inclined holes 201c, and the inclined holes 201c are provided with electromagnets 203 located inside the notches of the slide bar 101. The peripheral side of the central tube 303 is fixedly connected with a plurality of spray pipes 303a arranged linearly up and down, and the length of the spray pipes 303a is shortened from top to bottom. The ends of the spray pipes 303a are fixed with nozzles 304, and friction strips 401b whose lower surfaces exceed the lower surface of the bottom plate 102 are provided directly below the linkage strips 401.

[0042] When the above-mentioned structure is used, the single electromagnet 203 is energized, so that the magnetic force generated by it repels the magnetic plate 104, thereby pushing the slider 201 to slide along the slide bar 101, and then the slider 201 drives the central tube 303 to move along the slide bar 101, thereby driving the spray pipe 303a and the nozzle 304 to move, so that the nozzle 304 can spray the road with the same length as the slide bar 101, and at the same time, when the slider 201 moves, the slider 201 pushes the rubber rod 202 to move along the side of the slide bar 101, and then the rubber rod 202 pushes or pulls the other rubber rod 202. The slider 201 connected thereto moves, so that the two sliders 201 move in relative or opposite directions, thereby performing a comprehensive spraying treatment on the construction road surface on both sides of the device, and after the bottom plate 102 is set on the road surface, when the bottom plate 102 deviates to one side, it will drive the friction strip 401b to follow the movement, thereby the friction strip 401b drives the tooth plate 402 to rotate, and thereby controls the other friction strip 401b symmetrically set therewith to slide in the opposite direction, so that through the opposite pulling of the two friction strips 401b, the friction between the bottom plate 102 and the road surface is increased, the gripping ability of the bottom plate 102 is improved, and the displacement of the bottom plate 102 is avoided.

[0043] Further, according to Figure 4 , Figure 5 and Figure 8 It can be seen that the left and right end surfaces of the two slide bars 101 are fixed with abutment strips 101b, and the two end surfaces of the slider 201 are fixed with reset buttons 201b electrically connected to the cable ends of the adjacent electromagnets 203. When the slider 201 moves to the end position of the slider 101, the reset button 201b on the end surface of the slider 201 will abut against the abutment strip 101b, so that the abutment strip 101b presses the reset button 201b, so that the electromagnet 203 that is powered on at this time is powered off, and controls the other electromagnet 203 symmetrical thereto to be powered on and work. Since the electromagnet 203 is arranged in an eight-shaped shape, the magnetic force generated by the electromagnet 203 and the magnetic plate 10 4 repel each other, thereby pushing the corresponding electromagnet 203 to slide, and thereby driving the slider 201 connected thereto to move. A circular opening 102b is provided in the middle of the upper end surface of the bottom plate 102, and a positioning plate 301a located inside the circular opening 102b is fixed to the bottom surface of the water tank 301. The concentrating pipe 303 and the end surface of the slider 201 are connected by bolts. After the water tank 301 is installed on the bottom plate 102, the positioning plate 301a at the bottom of the water tank 301 can be located inside the circular opening 102b. Therefore, the circular opening 102b limits the positioning plate 301a, thereby limiting the water tank 301 and ensuring the stable position of the water tank 301.

[0044] Further, according to Figure 5It can be seen that the left and right parts of the lower end surface of the slide bar 101 are fixed with vertical rods 102a, and the lower end surface of the vertical rods 102a is fixedly connected to the upper end surface of the bottom plate 102. The vertical rods 102a support the position of the slide bar 101 to improve the stability of the movement of the slider 201.

[0045] Further, according to Figure 1 , Figure 6 and Figure 7 It can be seen that the lower end surface of the friction strip 401b is provided with a tooth opening 401b-1, and the opposite end surfaces of the two adjacent linkage strips 401 are provided with a tooth opening 401c meshing with the tooth plate 402, and a bar block 401a sliding in the internal position of the through opening 105a-1 is fixed between the friction strip 401b and the linkage strip 401. Through the opening of the tooth opening 401c, the linkage strip 401 and the tooth plate 402 are used in coordination. Therefore, when the tooth plate 402 rotates, the tooth plate 402 will drive the two meshing linkage strips 401 to move, and thereby drive the friction strip 401b to move.

[0046] It should be noted that the electronic structures used in the entire device are connected to an external controller, so as to control the initial power-on operation of the electromagnet 203 and the operation of the water pump in the water tank 301. At the same time, the water pump inside the water tank 301 and the coil on the electromagnet 203 are connected to an external power supply, so that the electromagnet 203 and the water pump inside the water tank 301 can be powered on. At the same time, when using the entire device, it is only necessary to ensure that the electromagnet 203 in one of the sliders 201 is powered on, and the electromagnet 203 in the other slider 201 is always in a power-off state. Example 2

[0047] See also Figure 3 and Figure 5 On the basis of Example 1, this example positions the rubber rod 202 by means of the bending tube 103 and the positioning tube 101a to ensure the stable sliding of the rubber rod 202.

[0048] Specifically, the upper end surface of the slider 201 is fixed with a movable plate 201a connected to the upper end surface of the slide bar 101, and the lower end surface of the movable plate 201a is fixed with a connecting plate 201a-1 located between the two slide bars 101. The two ends of the rubber soft rod 202 are respectively fixedly connected to the end surfaces of the connecting plate 201a-1. The rubber soft rod 202 located between the two slide bars 101 is U-shaped, and a bending tube 103 is sleeved on the middle position of the bending of the rubber soft rod 202. The bending tube 103 and the bottom plate 102 are fixedly connected by the arranged support bar 102c. Positioning tubes 101a are fixed at the positions where the opposite end surfaces of the two slide bars 101 are close to the bending tube 103, and the positioning tubes 101a are sleeved on the rubber soft rod 202.

[0049] By setting and using the above structure, after the slider 201 moves along the slide bar 101, the slider 201 will push or pull the rubber soft rod 202, so that the rubber soft rod 202 slides inside the bending tube 103 and the positioning tube 101a, ensuring the stable movement of the rubber soft rod 202. Example 3

[0050] See also Figure 4 and Fig. 9 On the basis of Example 1, this embodiment enables the electromagnet 203 to slide inside the inclined hole 201c, so as to facilitate positioning of the slider 201 at the corresponding position of the slide bar 101.

[0051] Specifically, a compression ring plate 203b is fixed to the end face of the electromagnet 203 inside the inclined hole 201c, an abutment ring 201d is fixed to the inner wall of the inclined hole 201c at the middle of the electromagnet 203, and the abutment ring 201d is sleeved on the electromagnet 203, and a spring 203a sleeved on the surface of the electromagnet 203 is fixed to the end face of the compression ring plate 203b, and the other end of the spring 203a abuts against the end face of the abutment ring 201d.

[0052] By setting up and using the above-mentioned structure, when the electromagnet 203 is powered off, the electromagnet 203 and the magnetic plate 104 are no longer in a state of repulsion, so the magnetic plate 104 will adsorb the iron rod of the electromagnet 203, causing the electromagnet 203 to slide a certain distance inside the inclined hole 201c, and then the electromagnet 203 will drive the abutment ring 201d to compress the spring 203a, so that the slider 201 is positioned at the position of the slide bar 101. Therefore, after the electromagnet 203 is powered on, the electromagnet 203 and the magnetic plate 104 are repelled, so that the spring 203a pushes the abutment ring 201d to reset, so that the electromagnet 203 is reset and moved to the inclined hole 201c. Example 4

[0053] See also Figure 6 , Figure 7 , Fig.10 and Fig.11 In this embodiment, the rotating plate 402b, the shaft 402a and the tooth plate 402 are installed and matched, so that the rotating plate 402b and the shaft 402a initially limit the tooth plate 402 to ensure that the tooth plate 402 is stably located inside the linkage port 105c.

[0054] Specifically, a rotating opening 105b is provided at the position of the upper end surface of the convex plate 105 corresponding to the linkage opening 105c, and the rotating opening 105b and the linkage opening 105c which are consistent in the upper and lower directions are connected through the opened shaft opening 105b-1, and the upper end surface of the tooth plate 402 is fixed with a shaft rod 402a which rotates in the internal position of the shaft opening 105b-1, and the upper end surface of the shaft rod 402a is fixed with a rotating plate 402b which rotates in the internal position of the rotating opening 105b.

[0055] Through the arrangement and use of the above-mentioned structure, when the tooth plate 402 is driven to rotate by the linkage bar 401, the tooth plate 402 will be in the internal position of the linkage port 105c, and the tooth plate 402 will drive the shaft rod 402a to rotate inside the rotating port 105b, thereby driving the rotating plate 402b to rotate in the internal position of the rotating port 105b. At the same time, the rotating plate 402b is in the rotating port 105b, and the shaft rod 402a is in the shaft port 105b-1. Therefore, the rotating plate 402b and the shaft rod 402a initially limit the tooth plate 402 to ensure that the tooth plate 402 is stably located in the internal position of the linkage port 105c.
