Description

Technical Field

[0001] The invention relates to the technical field of road crash wall maintenance, in particular to a walking device and a crash wall spraying automatic maintenance vehicle. 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. Currently, maintenance vehicles generally include 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 to rotate by a motor, and the rollers drive the walking frame and the water tank to move along the length of the crash barrier. Later, 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 higher efficiency; however, currently, the walking frame and the rollers are mostly fixedly connected, resulting in the inability to adjust the spacing between the rollers, making it difficult for the walking frame to adapt to crash barriers of different thicknesses. Summary of the invention

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

[0004] According to a walking device of the present invention, it 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 provided 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 provided 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 provided on the side of the vertical pole close to the anti-collision wall; an adjustment component is provided at the vertical pole, and the adjustment component is used to push the second rollers close to the anti-collision wall.

[0005] With the present invention, the construction workers first lift the installation shell and place it on the top of the anti-collision wall, so that the vertical poles under the installation shell are located on both sides of the anti-collision wall, and the first roller is pressed on the top of the anti-collision wall; then the construction workers start to use the adjustment component, first, 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, push the installation plate to move, and when the installation plate moves, it drives the second roller to approach the anti-collision wall, until the second roller is pressed tightly against the anti-collision wall, and 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 anti-collision wall, so that the installation shell can stay stably on the anti-collision wall, and can adapt to anti-collision walls of different thicknesses; The motor drives the first roller to move on the top of the anti-collision wall, so that the entire installation shell moves on the top of the anti-collision wall. During the movement of the installation shell, the second roller at the vertical pole below the installation shell presses against the side wall of the anti-collision wall and moves.

[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.

[0010] Preferably, a first connecting rod is provided at one end face of the mounting plate close to the threaded rod, and a first ball is provided at the end of the first connecting rod away from the mounting plate; a first limiting groove is provided at one end of the threaded rod for the first ball to extend into, and an opening diameter of the first limiting groove is larger than the diameter of the first connecting rod and smaller than the diameter of the first ball.

[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 device body 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 the rotation.

[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. When the mounting plate moves, it pulls the first guide rod 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 rolling of the second roller, the second roller will not tilt.

[0014] Preferably, a baffle is provided at one end of the first guide rod away from the mounting plate.

[0015] With the present invention, when the threaded rod rotates and extends into the threaded hole, the first guide rod also extends into the first through hole until the baffle on the first guide rod abuts against the side wall of the vertical rod, thereby preventing the first guide rod from being separated from the first through hole.

[0016] Preferably, the length of the first guide rod is shorter than the length of the threaded rod.

[0017] The present invention can prevent the first guide rod from contacting the handle, thereby preventing construction workers from being affected in turning the handle.

[0018] Preferably, the upright pole is made of square steel.

[0019] The present invention makes it easy to obtain materials at the construction site, and the square steel structure has greater strength.

[0020] Preferably, the vertical pole is connected to the mounting shell by welding.

[0021] The present invention makes it convenient for installers to connect the vertical pole and the installation shell.

[0022] The present invention provides an automatic anti-collision wall spraying maintenance vehicle, comprising the above-mentioned traveling device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] 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.

[0040] In this embodiment, a threaded hole 420 passing through the vertical rod 120 is provided at the side wall of the vertical rod 120 near the second roller 510; the adjustment assembly 130 includes a threaded rod 450 passing through the threaded hole 420; a U-shaped mounting plate 520 is provided at one end of the threaded rod 450, and the second roller 510 is rotatably connected to the mounting plate 520.

[0041] According to this embodiment, rotating rods are provided on both sides of the second roller 510, and bearings for inserting the rotating rods are provided at the mounting plate 520, so that the second roller 510 can move smoothly on the side wall of the anti-collision wall.

[0042] In this embodiment, a handle 560 is provided at one end of the threaded rod 450 away from the mounting plate 520 .

[0043] 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 .

[0044] 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.

[0045] 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 tilt due to rotation, preventing the second roller 510 from tilting, and making the second roller 510 not parallel to the anti-collision wall, affecting the device body 100 walking on the anti-collision wall.

[0046] 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.

[0047] 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 anti-collision wall side walls, and during the movement of the device body 100, the second roller 510 will not tilt, affecting the movement of the device body 100.

[0048] In this embodiment, the water pipeline 150 includes a first water pipe 930 arranged around the installation shell 110, and a plurality of second water pipes 940 are arranged on both sides of the crash wall along the height direction of the crash wall and connected to the first water pipe 930; the second water pipe 940 is provided with a plurality of third water pipes 1001 facing the crash wall and arranged at intervals along the length direction of the second water pipe 940; and a fourth water pipe 930 connecting the water tank and the first water pipe 930 is provided on the side wall of the installation shell 110.

[0050] In this embodiment, the sliding assembly 820 includes a sleeve 1103 connected to the third water pipe 1001, and a third limiting groove 1301 is provided in the sleeve 1103 for the third water pipe 1001 to extend into; two guide plates 1104 are provided at one end of the sleeve 1103 away from the third water pipe 1001 along the height direction of the anti-collision wall; a sliding block 1107 that moves along the length direction of the guide plate 1104 is provided between the two guide plates 1104, and the first nozzle 1106 is connected to the sliding block 1107; a hose 1202 is provided between the sliding block 1107 and the sleeve 1103, and both ends of the hose 1202 pass through the sliding block 1107 and the sleeve 1103 respectively, connecting the first nozzle 1106 and the third water pipe 1001.

[0051] Through this embodiment, when the construction personnel adjust the position of the sliding block 1107, they only need to push the sliding block 1107 to move along the guide plate 1104, and in the process of the construction personnel pushing the sliding block 1107 to move, the hose 1202 will also move with the movement of the sliding block 1107, thereby ensuring that the first nozzle 1106 and the third water pipe 1001 can remain connected when the sliding block 1107 moves.

[0052] In this embodiment, the guide plate 1104 is provided with a plurality of second through holes 1102 spaced apart along the length direction of the guide plate 1104, and the sliding block 1107 is provided with countersunk holes 1201 corresponding to the second through holes 1102; the guide plate 1104 is provided with a latch 1101, which is used to pass through the second through hole 1102 and extend into the countersunk hole 1201.

[0053] Through this embodiment, when the construction personnel move the sliding block 1107 to the appropriate position, the countersunk hole 1201 on the sliding block 1107 is aligned with the second through hole 1102 on the guide plate 1104, and then the pin 1101 is inserted into the second through hole 1102 and the countersunk hole 1201 to fix the sliding block 1107. At the same time, the movement of the first nozzle 1106 will also be restricted; thereby making it convenient for the construction personnel to fix the sliding block 1107.

[0054] In this embodiment, an inner wall of the third limiting groove 1301 is provided with an internal thread, and the third water pipe 1001 is provided with an external thread matching the internal thread.

[0055] Through this embodiment, the installer can twist the sleeve 1103 to make the internal thread on the inner wall of the third limiting groove 1301 cooperate with the external thread on the third water pipe 1001, thereby facilitating the installer to connect the sleeve 1103 to the third water pipe 1001.

[0056] This embodiment provides a method for using an automatic wall spray maintenance vehicle, the method is as follows: First, the construction workers lift the device body 100 and place it on the protective wall, so that the first roller 210 under the mounting shell 110 is pressed against the top of the protective wall, and the vertical pole 120 is located on both sides of the protective wall; then the construction workers use the adjustment component 130 to push the second roller 510 and press the second roller 510 against the anti-collision wall; use the sliding component 820 to adjust the position of the first nozzle 1106, and finally start the motor 140 and the water pump 910 to move the device body 100 along the protective wall.

[0057] Through this embodiment, it is convenient for construction workers to place the maintenance vehicle on crash barriers of different heights and thicknesses, and it is ensured that the maintenance vehicle can move and spray water on the crash barriers smoothly.

[0061] According to this embodiment, rotating rods are provided on both sides of the second roller 510, and bearings for inserting the rotating rods are provided at the mounting plate 520, so that the second roller 510 can move smoothly on the side wall of the anti-collision wall.

[0062] In this embodiment, a handle 560 is provided at one end of the threaded rod 450 away from the mounting plate 520 .

[0063] 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] 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.

[0066] 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.

[0067] 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.

[0068] In this embodiment, a baffle 550 is disposed at one end of the first guide rod 440 away from the mounting plate 520 .

[0069] 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.

[0070] In this embodiment, the length of the first guide rod 440 is shorter than the length of the threaded rod 450 .
