Description

Technical Field

[0001] The invention relates to the technical field of road crash wall maintenance, and in particular to an automatic crash wall spraying maintenance vehicle and a use method thereof. Background Art

[0002] When construction workers cast crash barriers on both sides of the road, they first need to install molds, then pour concrete into the molds, remove the molds after the concrete solidifies, and finally spray water on the crash barriers for maintenance; currently, water spraying maintenance is generally carried out in two ways. One is that construction workers hold water pipes in their hands, walk along the road and spray water on the crash barriers. Since the crash barriers are long, the efficiency of manual water spraying is low; the other is through a maintenance vehicle. The current maintenance vehicle generally includes a water tank and a walking frame stuck on the crash barrier. The walking frame is provided with rollers and a nozzle connected to the water tank through a water pipe. The rollers are driven by a motor to rotate, and the rollers drive the walking frame and the water tank to move along the length of the crash barrier. Then, during the movement of the walking frame, the nozzle sprays water from the water tank on the crash barrier. This method of water spraying maintenance has a high efficiency; However, currently the walking frame and the rollers are mostly fixedly connected, and the nozzles are fixedly connected to the water pipes, resulting in the inability to adjust the spacing between the rollers and the position of the nozzles, making the maintenance vehicle unable to adapt to crash walls of different thicknesses and heights. Summary of the invention

[0003] The present invention provides an automatic anti-collision wall spraying maintenance vehicle and a use method thereof, which can overcome certain or some defects of the prior art.

[0004] An automatic spraying maintenance vehicle for crash barriers according to the present invention comprises: a device body, the device body comprising a walking device for driving the device body to move along the crash barrier, and a spraying device that cooperates with the walking device to spray water on the crash barrier when the device body moves; The walking device includes a mounting shell arranged above the anti-collision wall, a plurality of first rollers in contact with the top of the anti-collision wall are arranged at the bottom of the mounting shell, and a motor for driving the first rollers to rotate; a plurality of vertical poles connected to the mounting shell and arranged at intervals along the length direction of the anti-collision wall are arranged on both sides of the anti-collision wall; a plurality of second rollers arranged at intervals along the length direction of the vertical pole are arranged on one side of the vertical pole close to the anti-collision wall; an adjusting component is arranged at the vertical pole, and the adjusting component is used to push the second rollers close to the anti-collision wall; The spray device includes an installation shell arranged above the crash barrier, in which a water tank is arranged; a plurality of first nozzles for spraying water in the water tank onto the crash barrier are arranged on both sides of the crash barrier; water pipes for connecting the first nozzles and the water tank are also arranged on both sides of the crash barrier, and a water pump is arranged at one end of the water pipe close to the water tank; a sliding assembly is arranged at one end of the water pipe close to the first nozzle, and the sliding assembly is used to adjust the movement of the first nozzle along the height direction of the crash barrier.

[0005] According to the present invention, when the construction workers spray water to maintain the crash barriers on both sides of the road, they first lift the main body of the device and place it on the top of the crash barrier, so that the vertical poles under the main body of the device are located on both sides of the crash barrier, and the first roller is pressed on the top of the crash barrier; then the construction workers start to use the adjustment component, first, they rotate the threaded rod to make the threaded rod extend into the threaded hole, and in the process of the threaded rod extending into the threaded hole, they push the mounting plate to move, and when the mounting plate moves, it drives the second roller to approach the crash barrier, until the second roller is pressed tightly against the crash barrier, and then the construction workers stop rotating the threaded rod; then the construction workers rotate the threaded rods on the remaining vertical poles in turn, so that the second rollers at one end of the remaining threaded rods are pressed tightly against the crash barrier, so that the main body of the device can stably stay on the crash barrier, and can adapt to crash barriers of different thicknesses; After the device body can stay stably on the anti-collision wall, the construction personnel start to adjust the sliding assembly. First, the construction personnel push the sliding block according to the height of the anti-collision wall to make the sliding block move along the guide plate until the sliding block stays at a suitable height. Then, the construction personnel insert the latch through the second through hole into the countersunk hole on the sliding block to fix the sliding block, so that the first nozzle on the sliding block is at a suitable height, so that the first nozzle can cover a larger area of ​​the anti-collision wall when spraying water, adapting to anti-collision walls of different heights, and preventing the anti-collision wall from having unsprayed areas, which affects the quality of the anti-collision wall. After the height adjustment of the first nozzle is completed, the construction personnel open the control cabinet, and then start the water pump in the water tank through the control switch in the control cabinet. After the water pump is started, water is pumped into the water pipeline. The water passes through the water pipeline to the first nozzle and is sprayed on the crash barrier by the first nozzle; then the construction personnel start the motor again, and the motor drives the first roller to move on the top of the crash barrier, so that the entire device body moves on the top of the crash barrier. During the movement of the device body, the second roller at the vertical pole below the device body is pressed against the side wall of the crash barrier and moves, so that the device body can move stably on the crash barrier.

[0006] Preferably, a threaded hole passing through the vertical rod is provided at the side wall of the vertical rod near the second roller; the adjustment assembly includes a threaded rod passing through the threaded hole; a U-shaped mounting plate is provided at one end of the threaded rod, and the second roller is rotatably connected to the mounting plate.

[0007] According to the present invention, rotating rods are arranged on both sides of the second roller, and bearings for inserting the rotating rods are arranged on the mounting plate, so that the second roller can move smoothly on the side wall of the anti-collision wall.

[0008] Preferably, a handle is provided at one end of the threaded rod away from the mounting plate.

[0009] With the present invention, construction workers can rotate the threaded rod by rotating the handle, thereby making it convenient for construction workers to rotate the threaded rod.

[0011] Through the present invention, since the shape of the anti-collision wall is mostly trapezoidal, the side walls of the anti-collision wall are mostly inclined, and the mounting plate can be rotated in multiple directions with the first sphere as the center, so that the second roller can be perpendicular to the side wall of the anti-collision wall, increasing the contact area between the second roller and the side wall of the anti-collision wall, so that the main body of the device can walk on the anti-collision wall more stably; at the same time, when the construction personnel rotate the threaded rod, the mounting plate will not rotate, so that the second roller will not tilt due to rotation, preventing the second roller from tilting, making the second roller not parallel to the anti-collision wall, affecting the main body of the device walking on the anti-collision wall.

[0012] Preferably, second connecting rods connected to the mounting plate are provided on both sides of the first connecting rod, and a second ball is provided at the end of the second connecting rod away from the mounting plate; first through holes passing through the vertical rod are provided on both sides of the threaded hole, and first guide rods passing through the first through holes are provided on both sides of the threaded rod; a second limiting groove for the second ball to extend into is provided at one end of the first guide rod close to the mounting plate, and the opening diameter of the second limiting groove is larger than the diameter of the second connecting rod and smaller than the diameter of the second ball.

[0013] Through the present invention, when the construction workers rotate the threaded rod, the threaded rod extends into the threaded hole and pushes the mounting plate to move, and when the mounting plate moves, the first guide rod is pulled to move along the first through hole, thereby better improving the stability of the threaded rod when moving; because the second ball extends into the second limiting groove on the first guide rod, and the first ball extends into the first limiting groove on the threaded rod, the mounting plate always remains horizontal and can swing up and down, so that the mounting plate can remain perpendicular to the inclined surfaces of different anti-collision wall side walls, and during the movement of the device body, the second roller will not tilt, affecting the movement of the device body.

[0014] Preferably, the water pipeline includes a first water pipe arranged around the installation shell, and a plurality of second water pipes are arranged on both sides of the crash wall along the height direction of the crash wall and connected to the first water pipe; a plurality of third water pipes are arranged at the second water pipe, facing the crash wall and arranged at intervals along the length direction of the second water pipe; a fourth water pipe connecting the water tank and the first water pipe is provided at the side wall of the installation shell.

[0015] With the present invention, the first water pipe surrounds the installation shell, the second water pipe is attached to the vertical pole, and the second water pipe and the vertical pole are tied together by a belt; thus, the water pipeline is conveniently fixed to the device body.

[0016] Preferably, the sliding assembly includes a sleeve connected to the third water pipe, and the sleeve is provided with a third limiting groove for the third water pipe to extend into; two guide plates arranged along the height direction of the anti-collision wall are provided at the end of the sleeve away from the third water pipe; a sliding block that moves along the length direction of the guide plates is provided between the two guide plates, and the first nozzle is connected to the sliding block; a hose is provided between the sliding block and the sleeve, and both ends of the hose pass through the sliding block and the sleeve respectively, connecting the first nozzle and the third water pipe.

[0017] According to the present invention, when construction workers adjust the position of the sliding block, they only need to push the sliding block to move along the guide plate. In the process of the construction workers pushing the sliding block to move, the hose will also move with the movement of the sliding block, thereby ensuring that the first nozzle and the third water pipe can maintain communication when the sliding block moves.

[0018] Preferably, the guide plate is provided with a plurality of second through holes spaced apart along the length direction of the guide plate, and the sliding block is provided with countersunk holes corresponding to the second through holes; the guide plate is provided with a latch pin, which is used to pass through the second through hole and extend into the countersunk hole.

[0019] Through the present invention, when the construction workers move the sliding block to a suitable position, the countersunk hole on the sliding block is aligned with the second through hole on the guide plate, and then the pin is inserted into the second through hole and the countersunk hole to fix the sliding block. At the same time, the movement of the first nozzle will also be restricted; thereby, it is convenient for the construction workers to fix the sliding block.

[0020] Preferably, an internal thread is provided at the inner side wall of the third limiting groove, and an external thread matching the internal thread is provided at the third water pipe.

[0021] With the present invention, the installer can twist the sleeve to make the internal thread at the inner side wall of the third limiting groove match the external thread on the third water pipe, thereby making it convenient for the installer to connect the sleeve to the third water pipe.

[0022] The present invention provides a method for using an automatic anti-collision wall spraying maintenance vehicle, the method is as follows: First, the construction workers lift the main body of the device and place it on the protective wall, so that the first roller under the mounting shell is pressed against the top of the protective wall and the vertical poles are located on both sides of the protective wall; then the construction workers use the adjustment component to push the second roller and press the second roller against the anti-collision wall; use the sliding component to adjust the position of the first nozzle, and finally start the motor and the water pump to move the main body of the device along the protective wall.

[0023] The present invention can facilitate construction workers to smoothly place the maintenance vehicle on crash barriers of different heights and thicknesses, and can ensure that the maintenance vehicle can smoothly move and spray water on the crash barrier. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Through this embodiment, when the construction personnel spray water to maintain the crash barriers on both sides of the road, they first lift the device body 100 and place it on the top of the crash barrier, so that the vertical poles 120 below the device body 100 are located on both sides of the crash barrier, and the first roller 210 is pressed on the top of the crash barrier; then the construction personnel start to use the adjustment component 130, first, rotate the threaded rod 450, so that the threaded rod 450 extends into the threaded hole 420, and in the process of the threaded rod 450 extending into the threaded hole 420, push the mounting plate 520 to move, and when the mounting plate 520 moves, it drives the second roller 510 to approach the crash barrier, until the second roller 510 is pressed against the crash barrier, and the construction personnel stop rotating the threaded rod 450; then the construction personnel rotate the threaded rods 450 on the remaining vertical poles 120 in turn, so that the second roller 510 at one end of the remaining threaded rods 450 is pressed against the crash barrier, so that the device body 100 can stay stably on the crash barrier, and can adapt to crash barriers of different thicknesses; After the device body 100 can stably stay on the anti-collision wall, the construction personnel start to adjust the sliding assembly 820. First, the construction personnel push the sliding block 1107 according to the height of the anti-collision wall, so that the sliding block 1107 moves along the guide plate 1104. After the sliding block 1107 stays at a suitable height, the construction personnel then pass the latch 1101 through the second through hole 1102 and extend it into the countersunk hole 1201 on the sliding block 1107, thereby fixing the sliding block 1107 and making the first nozzle 1106 on the sliding block 1107 at a suitable height, so that the first nozzle 1106 can cover a larger area of ​​the anti-collision wall when spraying water, adapting to anti-collision walls of different heights, and preventing the anti-collision wall from having an unsprayed area, which affects the quality of the anti-collision wall; After the height adjustment of the first nozzle 1106 is completed, the construction personnel open the control cabinet 160, and then first start the water pump 910 in the water tank through the control switch in the control cabinet 160. After the water pump 910 is started, water is pumped into the water pipeline 150. The water passes through the water pipeline 150 to the first nozzle 1106 and is sprayed on the crash barrier by the first nozzle 1106; then the construction personnel start the motor 140 again, and the motor 140 drives the first roller 210 to move on the top of the crash barrier, so that the entire device body 100 moves on the top of the crash barrier. During the movement of the device body 100, the second roller 510 at the vertical pole 120 below the device body 100 is pressed against the side wall of the crash barrier and moves, so that the device body 100 can move stably on the crash barrier.

[0063] In this embodiment, a handle 560 is provided at one end of the threaded rod 450 away from the mounting plate 520 .

[0064] According to this embodiment, the construction personnel rotate the handle 560 to rotate the threaded rod 450 , thereby facilitating the construction personnel to rotate the threaded rod 450 .

[0065] In this embodiment, a first connecting rod 720 is provided at one end face of the mounting plate 520 close to the threaded rod 450, and a first ball 730 is provided at one end of the first connecting rod 720 away from the mounting plate 520; a first limiting groove 740 for the first ball 730 to extend into is provided at one end of the threaded rod 450, and an opening diameter of the first limiting groove 740 is larger than the diameter of the first connecting rod 720 and smaller than the diameter of the first ball 730.

[0066] Through this embodiment, since the shape of the anti-collision wall is mostly trapezoidal, the side walls of the anti-collision wall are mostly inclined, and the mounting plate 520 can be rotated in multiple directions with the first sphere 730 as the center, so that the second roller 510 can be perpendicular to the side wall of the anti-collision wall, increasing the contact area between the second roller 510 and the side wall of the anti-collision wall, so that the device body 100 can walk on the anti-collision wall more stably; at the same time, when the construction personnel rotate the threaded rod 450, the mounting plate 520 will not rotate, so that the second roller 510 will not be tilted due to the rotation.

[0067] In this embodiment, second connecting rods 530 connected to the mounting plate 520 are provided on both sides of the first connecting rod 720, and a second ball 540 is provided on the end of the second connecting rod 530 away from the mounting plate 520; first through holes 430 passing through the vertical rod 120 are provided on both sides of the threaded hole 420, and first guide rods 440 passing through the first through holes 430 are provided on both sides of the threaded rod 450; a second limiting groove 710 for the second ball 540 to extend into is provided on the end of the first guide rod 440 close to the mounting plate 520, and the opening diameter of the second limiting groove 710 is larger than the diameter of the second connecting rod 530, and smaller than the diameter of the second ball 540.

[0068] Through this embodiment, when the construction personnel rotate the threaded rod 450, the threaded rod 450 extends into the threaded hole 420 and pushes the mounting plate 520 to move. When the mounting plate 520 moves, it pulls the first guide rod 440 to move along the first through hole 430, thereby better improving the stability of the threaded rod 450 when moving; because the second ball 540 extends into the second limiting groove 710 on the first guide rod 440, and the first ball 730 extends into the first limiting groove 740 on the threaded rod 450, the mounting plate 520 always remains horizontal and can swing up and down, so that the mounting plate 520 can remain perpendicular to the inclined surfaces of different side walls of the anti-collision wall, and during the rolling process of the second roller 510, the second roller 510 will not tilt.

[0069] In this embodiment, a baffle 550 is disposed at one end of the first guide rod 440 away from the mounting plate 520 .

[0070] Through this embodiment, when the threaded rod 450 rotates and extends into the threaded hole 420, the first guide rod 440 will also extend into the first through hole 430 until the baffle 550 on the first guide rod 440 abuts against the side wall of the vertical rod 120; thereby preventing the first guide rod 440 from disengaging from the first through hole 430.

[0071] In this embodiment, the length of the first guide rod 440 is shorter than the length of the threaded rod 450 .

[0072] Through this embodiment, the first guide rod 440 is prevented from contacting the handle 560 and affecting the construction workers' rotation of the handle 560 .
