Description

Technical Field

[0001] This invention relates to the field of water spray frame angle adjustment technology, specifically to a water spray frame angle adjustment device and adjustment method for sanitation vehicles. Background Technology

[0002] Environmental sanitation refers to the control of all factors in the environment surrounding human activities that hinder or affect health. The scope of environmental sanitation is very complex and extensive, with dust pollution being one of the most significant impacts on humans in cities. With the increasing prevalence of vehicles in cities and the deteriorating environment, especially in northern cities with little rain and frequent winds, dust poses a significant threat to human health. Therefore, sanitation sprinkler trucks are needed to continuously spray water on major urban roads to suppress the prolonged floating of dust.

[0003] Currently, the water sprinkler trucks used by sanitation workers all have water spray pipes at the rear, and the length of these pipes is fixed. This sometimes leads to a waste of water resources, and sometimes it prevents them from passing through narrow roads. When not spraying water, the long water spray pipes also extend out of the vehicle body, which can easily cause traffic accidents and is not conducive to sanitation vehicles cleaning complex road conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for adjusting the angle of the water spray frame of a sanitation vehicle, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sanitation vehicle water spray frame angle adjustment device and adjustment method, including a garbage truck compartment and a lifting plate. Two lifting plates are installed at the end of the garbage truck compartment away from the driver's cab via screws. A floor washing pipe is movably installed at the bottom of the lifting plate, and an adjustment component for adjusting the angle of the floor washing pipe is provided at the bottom of the lifting plate.

[0006] The adjustment assembly includes a mounting bracket and a U-shaped bracket. A connecting rod is fixedly mounted on the top of the mounting bracket, and the bottom of the mounting bracket is fixedly connected to the outer wall of the floor scrubbing pipe. The U-shaped bracket is rotatably sleeved on the outer wall of the connecting rod, and the top of the U-shaped bracket is movably connected to the bottom of the lifting plate. An installation box is fixedly mounted on the inner wall of the U-shaped bracket. The top of the connecting rod extends into the inner cavity of the installation box, and a worm gear is fixedly mounted on one end of the connecting rod that extends into the installation box. A worm gear that meshes with the worm gear is rotatably mounted in the inner cavity of the installation box.

[0007] The inner wall of the mounting box is fixedly equipped with a power output device for worm gear rotation.

[0008] Preferably, the bottom of the mounting box has a through hole that communicates with its own inner cavity, and the top of the connecting rod passes through the through hole and extends into the inner cavity of the mounting box.

[0009] Preferably, a transmission bearing is fixedly sleeved on the outer wall of the connecting rod, and the bottom of the U-shaped frame has a mounting hole that communicates with its own inner wall. The outer wall of the transmission bearing and the inner wall of the mounting hole are fixedly connected.

[0010] Preferably, the adjustment assembly further includes a support plate, with rotating shafts fixedly installed on both sides of the U-shaped frame, one side of the support plate being rotatably connected to the end of the rotating shaft away from the U-shaped frame, and the top of the support plate being fixedly connected to the bottom of the lifting plate.

[0011] Preferably, a transmission gear is fixedly sleeved on the outer wall of the rotating shaft, and a guide rail is fixedly installed at the bottom of the lifting plate. The guide rail is located directly above the transmission gear, and a rack plate that engages with the transmission gear is slidably installed inside the guide rail. A bidirectional threaded rod is provided in the inner cavity of the guide rail. The two rack plates located inside the two guide rails each have a threaded hole at one adjacent end that communicates with their other end. The two ends of the bidirectional threaded rod pass through the two threaded holes and are rotatably connected to the inner wall of the guide rail.

[0012] Preferably, one end of each of the two guide rails is provided with an insertion hole that communicates with its own inner cavity, one end of each of the two bidirectional threaded rods passes through the insertion hole and extends to the outside of the guide rail, and a tensioning wheel is fixedly installed at the end of each of the two bidirectional threaded rods that extends to the outside of the guide rail. The two tensioning wheels are rotatably connected by a tensioning belt, and a drive motor is connected to the end of one of the tensioning wheels that is away from the bidirectional threaded rod.

[0013] Preferably, the power output end of the drive motor is fixedly connected to one of the tensioning wheels at the end away from the bidirectional threaded rod, and the housing of the drive motor is detachably mounted with a support frame, one end of which is fixedly connected to the outer wall of one of the lifting plates.

[0014] Preferably, the top of the rack plate is rotatably mounted with multiple transmission balls that fit against the inner wall of the guide rail.

[0015] The method for adjusting the angle of the sprinkler frame on a sanitation vehicle includes the following steps:

[0016] A1. Start the power output device to rotate the worm gear. At this time, the connecting rod rotates along with the worm wheel, thereby changing the angle between the floor scrubbing pipe and the garbage truck compartment, as well as the relative position between the two floor scrubbing pipes. When the two floor scrubbing pipes are parallel to each other, the space occupied by the floor scrubbing pipes is reduced, so that the sanitation truck can drive on narrower roads. When the two floor scrubbing pipes are rotated to the same horizontal line, the area occupied by the two floor scrubbing pipes is the largest, which is conducive to increasing the area and speed of cleaning the ground, so as to facilitate the sanitation truck to clean complex road conditions.

[0017] A2. Adjust the two floor scrubbing pipes to be parallel to each other, and then pull the rack plate to make the rack plate located inside the same guide rail slide towards each other until the two floor scrubbing pipes rotate so that the nozzles no longer point to the ground. At this time, the water sprayed from the nozzles can suppress dust in the air around the sanitation vehicle.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention allows for adjustment of the angle between two floor cleaning pipes via an adjustable component. This facilitates adjusting the distance between the two pipes according to the terrain, thereby increasing the area and speed of floor cleaning and enabling sanitation vehicles to clean complex road conditions.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figure 1-4This embodiment provides a sanitation vehicle water spray frame angle adjustment device and adjustment method, including a garbage truck body 1 and a lifting plate 2. Two lifting plates 2 are installed at the end of the garbage truck body 1 away from the driver's cab via a screw. A motor for rotating the screw is fixedly installed at the end of the garbage truck body 1 away from the driver's cab. By changing the rotation direction of the screw, the height of the lifting plate 2 off the ground is controlled.

[0028] A floor cleaning pipe 10 is movably installed at the bottom of the lifting plate 2, and an adjustment component for adjusting the angle of the floor cleaning pipe 10 is provided at the bottom of the lifting plate 2. A nozzle connected to its own inner cavity is installed on the outer wall of the floor cleaning pipe 10. The nozzle is used to spray water inside the floor cleaning pipe 10 onto the ground, thereby achieving the purpose of cleaning the road.

[0029] The adjustment assembly includes a mounting frame 9 and a U-shaped frame 7. A connecting rod 8 is fixedly installed on the top of the mounting frame 9, and the bottom of the mounting frame 9 is fixedly connected to the outer wall of the floor scrubbing pipe 10. The mounting frame 9 can support the floor scrubbing pipe 10, which is beneficial for the assembly between the floor scrubbing pipe 10 and the lifting plate 2.

[0030] The U-shaped frame 7 is rotatably sleeved on the outer wall of the connecting rod 8, and the top of the U-shaped frame 7 is movably connected to the bottom of the lifting plate 2. The U-shaped frame 7 can support the mounting frame 9, which is beneficial for installing the mounting frame 9 at the bottom of the lifting plate 2 and adjusting the height of the floor cleaning pipe 10 off the ground with the lifting plate 2.

[0031] A mounting box 6 is fixedly installed on the inner wall of the U-shaped frame 7. The top of the connecting rod 8 extends into the inner cavity of the mounting box 6, and a worm gear 14 is fixedly installed at one end of the connecting rod 8 extending into the mounting box 6. A worm 13, which meshes with the worm gear 14, is rotatably installed in the inner cavity of the mounting box 6. A power output device for rotating the worm 13 is fixedly installed on the inner wall of the mounting box 6. The power output device consists of a drive motor, and the power output end of the drive motor is fixedly connected to one end of the worm 13. When the power output device is started, the worm 13 rotates. When the worm gear 14 rotates, the connecting rod 8 rotates along with the worm wheel 14, thereby changing the angle between the floor washing pipe 10 and the garbage truck compartment 1, as well as the relative position between the two floor washing pipes 10. When the two floor washing pipes 10 are parallel to each other, the space occupied by the floor washing pipes 10 is reduced, so that the sanitation truck can drive on narrower roads. When the two floor washing pipes 10 rotate to be on the same horizontal line, the area occupied by the two floor washing pipes 10 is the largest, which is conducive to increasing the area and speed of cleaning the ground, so as to facilitate the sanitation truck to clean complex road conditions.

[0032] The bottom of the mounting box 6 has a through hole that communicates with its own inner cavity. The top of the connecting rod 8 passes through the through hole and extends into the inner cavity of the mounting box 6, which facilitates the extension of the top of the connecting rod 8 into the interior of the mounting box 6.

[0033] A transmission bearing 15 is fixedly sleeved on the outer wall of the connecting rod 8. The bottom of the U-shaped frame 7 has a mounting hole that communicates with its own inner wall. The outer wall of the transmission bearing 15 is fixedly connected to the inner wall of the mounting hole. The transmission bearing 15 can prevent the outer wall of the connecting rod 8 from contacting the inner wall of the mounting hole, effectively reducing the friction when the connecting rod 8 rotates.

[0034] Example 2

[0035] Please see Figure 1-4 Further improvements made based on Example 1:

[0036] The adjustment assembly also includes a support plate 5, and rotating shafts are fixedly installed on both sides of the U-shaped frame 7. One side of the support plate 5 is rotatably connected to the end of the rotating shaft away from the U-shaped frame 7, and the top of the support plate 5 is fixedly connected to the bottom of the lifting plate 2. The cooperation between the support plate 5 and the rotating shaft allows the two floor cleaning pipes 10 to rotate along the axis of the rotating shaft.

[0037] A transmission gear 3 is fixedly sleeved on the outer wall of the rotating shaft, and a guide rail 4 is fixedly installed at the bottom of the lifting plate 2. The guide rail 4 is located directly above the transmission gear 3, and a rack plate 12 that engages with the transmission gear 3 is slidably installed inside the guide rail 4. When it is necessary to suppress dust in the air, the two floor washing pipes 10 are adjusted to be parallel to each other, and then the rack plate 12 is pulled to make the rack plate 12 located inside the same guide rail 4 slide towards each other until the two floor washing pipes 10 rotate until the nozzles no longer point to the ground. At this time, the water sprayed from the nozzles can suppress dust in the air around the sanitation vehicle.

[0038] A bidirectional threaded rod 11 is provided in the inner cavity of the guide slide rail 4. The two rack plates 12 located inside the two guide slide rails 4 each have a threaded hole at one adjacent end that communicates with the other end of itself. The two ends of the bidirectional threaded rod 11 pass through the two threaded holes and are rotatably connected to the inner wall of the guide slide rail 4. By rotating the bidirectional threaded rod 11, the distance between the two rack plates 12 can be adjusted with the cooperation of the threaded holes, and the rack plates 12 after being moved can be positioned to prevent the transmission gear 3 from rotating again when the bidirectional threaded rod 11 is stationary.

[0039] One end of each of the two guide rails 4 is provided with an insertion hole that communicates with its own inner cavity. One end of each of the two bidirectional threaded rods 11 passes through the insertion hole and extends to the outside of the guide rail 4. Tensioning wheels are fixedly installed at the ends of the two bidirectional threaded rods 11 that extend to the outside of the guide rail 4. The two tensioning wheels are rotatably connected by a tensioning belt, which is conducive to the synchronous rotation of the two bidirectional threaded rods 11.

[0040] One of the tensioning wheels is connected to a drive motor at the end away from the bidirectional threaded rod 11. The power output end of the drive motor is fixedly connected to the end of one of the tensioning wheels away from the bidirectional threaded rod 11. The housing of the drive motor is detachably mounted with a support frame. One end of the support frame is fixedly connected to the outer wall of one of the lifting plates 2. The power output end of the drive motor is fixedly connected to one end of one of the tensioning wheels. The drive motor can rotate one of the tensioning wheels, which is beneficial to the synchronous rotation of the two bidirectional threaded rods 11.

[0041] Multiple transmission balls 16 that fit against the inner wall of the guide rail 4 are rotatably mounted on the top of the rack plate 12. Multiple transmission balls 16 are rotatably mounted on the top of the rack plate 12 along its outer wall. When the rack plate 12 rotates, the transmission balls 16 can effectively reduce the friction when the rack plate 12 slides, thus improving the smoothness of the rack plate 12 sliding back and forth.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
