Description

Technical Field

[0001] The utility model belongs to the field of garbage or residual material collecting vehicles, and in particular relates to a multifunctional sanitation sweeper. Background Art

[0002] With the rapid development of my country's economy, the cargo volume of coastal ports continues to increase. Bulk materials such as coal, sand, and ore are transported to port terminals by ships, and then mainly transported from ports to all parts of the country by freight trains. The bulk material unloading method of freight train carriages is to tip the carriage sideways. After unloading, there will be a lot of residual material in the carriage. Because the train cannot guarantee that the materials transported this time will be consistent with the next time, in order to avoid mixing different materials, the empty carriage needs to be cleaned before loading. At present, the cleaning of domestic port carriages is mainly done by opening the side doors of the carriages, and manually entering to clean, collect and transport the residual materials. The labor intensity is high, the efficiency is low, and the dust is large, which is not conducive to the health of operators. At the same time, through the search of patents, some ports use equipment to collect residual materials. For example, the existing patents: CN116946072A and CN116946073A freight train carriage cleaning robots, the equipment mainly uses robots for internal cleaning operations, the robot has fewer residual material storage devices, and needs to unload materials frequently. Because the robot has no independent power supply (the independent power supply is not enough to support the robot to work for a long time, and requires frequent charging, which is inefficient), it needs a wired connection, resulting in a small range of robot activities. The carriage needs to be moved forward so that the robot can clean the carriage within its movable range. During the operation, the robot needs to manually build guide rails to assist the robot in moving operations, and its own structure is too sophisticated and complex. Its operating scene is relatively harsh, making the stability of the equipment questionable. For example, the existing patents CN108217237A and CN116331151A disclose a train carriage cleaning vehicle, including a cleaning vehicle track, a gantry frame, a lifting and lowering cleaning device and a cleaning material collecting and conveying device; a walking device is provided under the cleaning vehicle gantry frame, which is connected to the cleaning vehicle track through the walking device and can move along the cleaning vehicle track; the lifting and lowering cleaning device is connected to the cleaning vehicle gantry frame through a slide rail and a slider pair and is located at the center of the cleaning vehicle gantry frame, and is connected to the cleaning vehicle gantry frame through a lifting mechanism and can move up and down along the cleaning vehicle gantry frame, and is used to clean the bottom of the train carriage, has no independent power supply and requires a wired connection, has a small range of movement, and the unloading range is next to the cleaning equipment, requires the train to move to cooperate with the operation, has poor flexibility, and has low cleaning efficiency. For example, the existing patents CN115320547A and CN218258080U disclose a train cargo compartment residual material cleaning and collection vehicle, which is derived from a washing and sweeping vehicle. The cleaning device of the washing and sweeping vehicle is changed from being installed and operated at the bottom to being installed and operated at the top. The working structure and principle of the washing and sweeping vehicle are borrowed, and the cleaning device is delivered to the bottom of the compartment by adding a swing arm lifting and swinging mechanism. The running vehicle turns on the cleaning device to collect the residual material at the bottom of the stationary train compartment. The cleaning vehicle solves the problem that the cleaning and unloading range of the above-mentioned patented equipment is small and the train needs to move forward to cooperate with the operation. However, the function is relatively single and the idle rate of the vehicle is high. The driver (on the left side of the vehicle) and the cleaning device (the vehicle is deflected 90° to the right) are on the left and right, and the distance is far, which makes it inconvenient to judge the distance and the operation is difficult. When there is a lot of residual material, the cleaning efficiency cannot be guaranteed, and there are dead corners and blind seams where residual material cannot be collected.

[0003] In summary, with the increasing market demand for train cargo compartment residual material cleaning machinery, the existing equipment has many usage limitations, and the market urgently needs multifunctional train compartment cleaning vehicles with complete functions and excellent operating effects.

[0031] The following will combine the drawings and specific embodiments to clearly and completely describe the technical solution of the utility model. Figure 1-15 As shown, a multifunctional sanitation sweeper includes a vehicle body and a front and a box device arranged on the vehicle body, the box device includes a residual material collection chamber 27 with a negative pressure environment, and a road cleaning device 32 is arranged below the vehicle body, characterized in that: a carriage cleaning device 33 for cleaning the interior of the carriage is arranged on the vehicle body, and the road cleaning device 32 and the carriage cleaning device 33 share the same residual material collection chamber 27 when sucking garbage. The carriage cleaning device 33 can be arranged on the vehicle body between the front and the box device, and can also be arranged at other positions as needed. The box device also includes a clean water chamber 28; a flushing device 31 and a dust suppression device 34 connected to the clean water chamber are arranged on the vehicle body; the residual material collection chamber 27 and the fan 7 with an engine 6 are connected through a pipeline to realize the negative pressure function. In the utility model, the sanitation vehicle with road sweeping and suction functions and the carriage cleaning device 33 are integrated, and the sanitation vehicle has multiple functions and can adapt to different work needs.

[0032] The carriage cleaning device 33 includes a carriage suction nozzle 25, the upper end of which is connected to the carriage pipe 3, and the carriage pipe 3 and the residual material collection chamber 27 are switched between being connected and closed; the road cleaning device 32 includes a road suction nozzle 26, the upper end of which is connected to the road pipe, and the road pipe and the residual material collection chamber 27 are switched between being connected and closed. When the carriage cleaning device 33 is working, the carriage pipe 3 and the residual material collection chamber 27 are connected, the ground pipe 5 and the residual material collection chamber 27 are disconnected, and the connection port of the residual material collection chamber 27 and the ground pipe 5 is in a closed state, that is, a non-connected and blocked state. This structure can prevent the residual material collection chamber 27 from being connected to the atmosphere through the ground pipe 5 when the carriage cleaning device 33 is working, causing insufficient air pressure in the box during operation and garbage flying out of the ground pipe 5. When the ground cleaning device is working, the connection port of the carriage pipe 3 and the residual material collection chamber 27 is also blocked to prevent the connection port of the residual material collection chamber 27 from passing through the atmosphere. The specific blocking position can be set at the open end, the middle, the connecting port, etc. of the pipeline, as long as other outlets outside the working position in the residual material collection chamber 27 are in a blocked state, thereby ensuring the negative pressure environment of the residual material collection chamber 27.

[0033] The carriage cleaning device 33 includes a mounting frame 30 which is arranged on the vehicle body and can move left and right and up and down. The carriage suction nozzle 25 is arranged at the lower end of the mounting frame 30. The carriage pipe 3 connected to the carriage suction nozzle 25 and the cover plate 1 used to block the connection port between the residual material collection chamber 27 and the carriage pipe 3 are fixedly arranged on the mounting frame 30. The mounting frame 30 switches between the working position and the standby position. In the standby position, the cover plate 1 is connected to the connection port of the residual material collection chamber 27. In the working position, the connection port of the carriage pipe 3 moves to communicate with the connection port of the residual material collection chamber 27. The position of the connection port of the cover plate 1 and the carriage pipe 3 is determined according to the actual situation. In the accompanying drawings, the height of the cover plate 1 is lower than the height of the connection port of the vehicle pipe; the position of the driver is the left side of the vehicle body, and the other side is the right side. The cover plate 1 is closer to the left side relative to the connection port of the carriage pipe 3. When the carriage cleaning mechanism is working, the mounting frame 30 is first raised, then moved to the left, and then lowered.

[0034] An external pipe 4 is arranged outside the residual material collection chamber 27, one end of the external pipe 4 extends into the residual material collection chamber 27, and the other end of the external pipe 4 is connected to the adjusting elbow 2, and the outlet of the adjusting elbow 2 is the connecting port of the residual material collection chamber 27 and the carriage pipe 3. The adjusting pipe is arranged outside the vehicle body, and the adjusting pipe is used to adjust the distance between the cover plate 1 and the connecting port of the carriage pipe 3 and the connecting port of the residual material collection chamber 27, so as to ensure that the cover plate 1, the connecting port of the carriage pipe 3 and the outlet of the adjusting elbow 2 are kept in a tight state when they are fitted. The adjusting elbow 2 can have a pipe with a certain buffer deformation or a buffer or elastic seal can be arranged at the outlet of the adjusting pipe.

[0035] A baffle 9 is provided at the open end of the road pipe extending into the residual material collection chamber 27, and an opening and closing cylinder 8 is provided between the baffle 9 and the outer wall of the road pipe. The opening and closing cylinder 8 is telescopic so that the baffle 9 switches between closing and opening the open end of the road pipe. Specifically, the baffle 9 can be rotatably provided at one side of the open end, and the opening and closing cylinder 8 is provided between the other side of the baffle 9 and the outer wall of the road pipe. Of course, other structures of opening and closing baffles 9 and other structures for blocking or opening road pipes can also be adopted, which will not be described in detail here.

[0036] A cleaning mechanism is arranged at the lower end of the mounting frame 30, and the cleaning mechanism includes a carriage suction nozzle 25 slidably arranged at the lower end of the mounting frame 30, a sweeping disc device 20 with bristles swingingly arranged at the lower end of the mounting frame 30 and located in front of the carriage suction nozzle 25, and a roller brush device 21 rotatably arranged behind the carriage suction nozzle 25; a lifting cylinder 24 is arranged between the carriage suction nozzle 25 and the mounting frame 30; and a suction nozzle roller 22 of the carriage cleaning device 33 is arranged on the outer side of the carriage suction nozzle 25. Among them, the sweeping disc device 20, the carriage suction nozzle 25 and the suction nozzle roller 22 are common structures in the washing and sweeping vehicle. You can refer to the existing technology. For example, the sweeping disc device 20 is set on the mounting frame 30 by rotating or swinging through a connecting rod, so that it can swing back and forth; the carriage suction nozzle 25 and the suction nozzle roller 22 are set at the lower end of the mounting frame 30 for sliding up and down as a whole, and are also connected to the lower end of the mounting frame 30 through a lifting cylinder 24. If the train carriage cleaning device 33 collides with the carriage due to the depression of the ground on which the vehicle is traveling during the cross-carriage transportation, the height of the train carriage cleaning device 33 from the ground can be raised by controlling the extension and retraction of the lifting cylinder 24. The sweeping disc device 20 cleans and gathers the garbage in the train carriage during operation. The suction nozzle roller 22 is used to support the carriage cleaning device 33 to walk in the carriage. Patent CN218258080U, a train cargo compartment residual material cleaning and collection vehicle, also has a detailed structure, which will not be described in detail. The roller brush device 21 can clean and gather the garbage behind the carriage suction nozzle 25 during the carriage cleaning operation, thereby improving the garbage recovery rate. In the utility model, the roller brush device 21 is arranged behind the carriage suction nozzle 25, and the roller brush device 21 moves together with the carriage suction nozzle 25, such as moving up and down on the mounting frame 30 with the undulations of the ground, and moving with the mounting frame 30. By performing triple sweeping and suction operations on the ground, the cleaning efficiency and garbage recovery rate can be effectively increased. The structure of the roller brush device 21 is a common cylinder with bristles, which is arranged at the lower part of the mounting frame 30 by rolling through a bearing.

[0037] The carriage cleaning device 33 includes a moving trolley arranged on the vehicle body for left and right movement, a column 29 arranged on the moving trolley for up and down movement, and a mounting frame 30 arranged on the upper end of the column 29 for left and right movement. A first linear drive mechanism is arranged between the vehicle body and the moving trolley, and a lifting drive mechanism is arranged between the moving trolley and the column 29; a second linear drive mechanism 19 is arranged between the column 29 and the mounting frame 30; and a limit cylinder 15 is also arranged on the vehicle body for pressing the moving trolley in the extended state to limit the carriage cleaning device 33. The structure of the column 29 can be determined according to the height to which the column 29 needs to rise. The column 29 can also be a multi-section sleeve structure, which is lifted by a multi-section lifting drive mechanism. For example, the column 29 includes a first column and a second column arranged on the first column for sliding up and down, and the moving trolley, the first column, and the second column constitute a three-section sleeve structure. The lifting drive mechanism includes a first lifting cylinder 13 arranged between the moving trolley and the first column, and a second lifting cylinder 14 arranged between the first column and the second column. When the entire carriage cleaning device 33 is at the far left or right, the limit cylinder 15 extends, and the limit device translates left and right to play a protective role. The first linear drive mechanism can be a hydraulic motor 17, which drives the wheels or gears of the mobile trolley to roll forward. A rack guide is provided on the vehicle body to enable the hydraulic motor 17 to move. The first linear drive mechanism can also adopt existing commonly used mechanisms, which are existing technologies and will not be described in detail. The second linear drive mechanism 19 can be a hydraulic cylinder.

[0038] A hand-held straw device 12 is provided on the vehicle body, and the hand-held straw device 12 can be connected to the residual material collection chamber 27 through a manual ball valve 10. When the manual ball valve 10 is opened, the hand-held straw device 12 is connected to the residual material collection chamber 27 to realize the dust collection function. When the manual ball valve 10 is closed, the passage between the residual material collection chamber 27 and the hand-held straw device 12 is closed and blocked to prevent the residual material collection chamber 27 from being connected to the atmosphere through this passage. The hand-held straw device 12 is composed of a transparent corrugated hose and a hand-held straw and other mechanisms. The structure can be regarded as the hand-held mechanism and garbage recycling mechanism of a vacuum cleaner, and can be manually held for fixed-point garbage recycling. In addition, a sewage alarm sensor 2323 is also provided on the box device, which can be used to detect the carrying capacity of the residual material collection chamber 27, and an alarm will be sounded to remind the driver to unload after it is fully loaded.

[0039] The carriage cleaning device 33 of the utility model shares a set of power, fan 7, box body and other devices with the road cleaning device 32, so that the vehicle can meet the road cleaning function and the cleaning function inside the freight carriage. At the same time, a handheld suction tube device 12 is added. When no road operation and train carriage cleaning operation are performed, the whole vehicle is regarded as a large vacuum cleaner, and the residual material in the carriage can be collected by manual operation. This function is mainly used when there is less residual material in the carriage and it must be cleaned, or for scenes where the vehicle and manual operation are difficult.

[0040] During specific implementation: the vehicle mainly has the following three uses (identities): a. As a washing and sweeping vehicle, it has all the washing and sweeping functions of a washing and sweeping vehicle to realize road washing and sweeping operations; b. As a freight train carriage sweeper, it has the function of cleaning the inside of the train carriage to realize cleaning operations inside the carriage; c. As a large vacuum cleaner, through manual operation, it can collect garbage or residual materials in vehicles and scenes that are difficult to operate manually.

[0041] Washing and sweeping vehicle: The specific functions of the washing and sweeping vehicle are existing technologies. It can realize multiple operation functions such as road sweeping, road brushing, high-pressure cleaning, curbstone brushing, garbage collection, sewage recycling, spraying and road isolation wall cleaning. It is equipped with a high-pressure spray gun, which can self-clean the entire vehicle and can also clean and remove pedestrian walkways and street advertisements. Please refer to the national standard QC / T 957-2013 washing and sweeping vehicle and related washing and sweeping vehicle patents.

[0042] When the washing and sweeping vehicle is used for washing and sweeping, the whole car cleaning device 33 needs to be in a non-operating state. At this time, the connection ports of the cover plate 1 and the adjusting elbow 2 need to be pressed together, the engine 6 is started to drive the fan 7 to rotate, and the opening and closing cylinder 8 is controlled by the cab display screen 11 to open the baffle 9, and the manual ball valve 10 is manually operated to close the manual ball valve 10 to avoid the hand-held suction pipe device 12 and the car suction nozzle 25 being in a through state with the atmosphere during operation, resulting in insufficient air pressure in the box and garbage flying out from the hand-held suction pipe device 12 and the car suction nozzle 25 when the washing and sweeping vehicle is operating, making it impossible to clean the road. Then, the vehicle is operated to select different operating modes and functions by operating the cab display screen 11 to realize all the washing and sweeping functions of the washing and sweeping vehicle.

[0043] Vacuum cleaner: The vehicle is regarded as a large vacuum cleaner. Vacuum cleaners have become a mature product in the industry. The working principle of the vacuum cleaner will not be described in detail. You can refer to the relevant vacuum cleaner standards and related vacuum cleaner patents to understand it.

[0044] When the vacuum cleaner is in operation, the entire carriage cleaning device 33 needs to be in a non-operating state. At this time, the connection ports of the cover plate 1 and the adjusting elbow 2 need to be pressed together, the auxiliary engine 6 is started to drive the fan 7 to rotate, the cab display screen 11 controls the opening and closing of the cylinder 8, the baffle 9 is in a closed state, and the manual ball valve 10 is in an open state to prevent the carriage suction nozzle 25 and the road suction nozzle 26 from being in a through state with the atmosphere during operation, resulting in insufficient air pressure in the box and garbage flying out of the carriage suction nozzle 25 and the road suction nozzle 26 when the washing and sweeping vehicle is operating, making it impossible to clean the road. Then operate the vehicle, select the vacuuming mode by operating the cab display screen 11, and manually operate the handheld suction pipe device 12 to realize the vacuum cleaner function.

[0045] Carriage cleaning vehicle for freight trains: The vehicle has the function of cleaning freight train carriages, and can also handle the cleaning work of a few freight vehicle carriages and some platforms. Because the driver is on the left, the entire carriage cleaning device 33 adopts a mechanism that can be translated to the left side of the vehicle, making it more convenient for the driver to operate and observe.

[0046] When cleaning the carriage, the vehicle needs to be parked on the left side of the train carriage, and a certain distance needs to be maintained between the vehicle and the outermost side of the carriage. Then, the engine 6 is started to drive the fan 7 to rotate, and the opening and closing cylinder 8 is controlled through the operating screen to close the baffle 9. At the same time, the manual ball valve 10 is manually closed to prevent the hand-held straw device 12 and the road surface suction nozzle 26 from being in contact with the atmosphere during operation, resulting in insufficient air pressure in the box and garbage flying out from the hand-held straw device 12 and the road surface suction nozzle 26 during the operation of the washing and sweeping vehicle, making it impossible to clean the road. Then, the vehicle is operated to clean the train carriage by operating the cab display screen 11. The specific actions are as follows:

[0047] The first step is to control the first lifting cylinder 13 to raise the entire train carriage cleaning device 33 to state 1;

[0048] The second step is to control the second lifting cylinder 14 to raise the entire train carriage cleaning device 33 to state 2;

[0049] The third step is to control the limit cylinder 15 to retract to prevent the whole train carriage cleaning device 33 from shifting sideways due to external force or during vehicle transfer. The hydraulic motor 17 drives the whole train carriage cleaning device 33 to move outward to the left side of the whole vehicle on the rack guide rail 18 through the translation trolley 16, so that the whole train carriage cleaning device 33 is in state 3, and then the limit cylinder 15 is extended to prevent the whole train carriage cleaning device 33 from shifting sideways due to external force or during vehicle transfer, thereby preventing an accident.

[0050] Step 4: by controlling the second linear drive mechanism 19, the train carriage cleaning device 33 is moved outward to the left side of the whole vehicle to reach state 4;

[0051] Step 5: When the driver confirms that the train carriage cleaning device 33 will not collide with the inner wall of the carriage when it falls into the train carriage, he can control the lifting cylinder and the second lifting cylinder 14 to lower the entire train carriage cleaning device 33 to state 5. At this time, the train carriage cleaning device 33 is in a state of being flat on the bottom of the carriage, and the connection ports of the carriage pipe 3 and the regulating elbow 2 are in a stacked state.

[0052] The sixth step is to control the train carriage cleaning device 33 to operate by one-touch control through the cab display screen 11. During the operation, the sweeping disc device 20 is unfolded and rotated, and changes from the retracted state to the operating state. The rolling sweeping device, the engine 6 drives the fan 7 to rotate, and then a negative pressure is formed in the residual material collection chamber 27 in the box device. The principle is the same as that of a washing and sweeping vehicle and a vacuum cleaner. The residual material inside the carriage is swept by the sweeping disc device 20 and the rolling sweeping device and gathered in front of the suction nozzle device or below the inside. Then the driver drives the vehicle forward, driving the carriage cleaning device 33 to move forward in the carriage, so as to collect the residual material at the bottom of the carriage. During the process, the driver can selectively open the dust reduction waterway according to the dust situation during the operation;

[0053] Step 7: After the driver operates the vehicle to make the carriage cleaning device 33 reach the other end of the carriage to complete the residual material collection work, the driver needs to control the first lifting cylinder 13 and the second lifting cylinder 14 to make the carriage cleaning device 33 of the train in state 4;

[0054] Step 8: Drive the vehicle over the carriage and park at the end of another carriage, then repeat steps 5, 6 and 7 until the entire train is cleaned or the residual material collection chamber 27 is full of residual material and an alarm is sounded. A sewage alarm sensor 23 is installed in the residual material collection chamber 27 to monitor in real time whether the residual material collection chamber 27 is full of residual material. If the train carriage cleaning device 33 collides with the carriage due to the depression of the ground where the vehicle is traveling during the cross-carriage transportation, the height of the train carriage cleaning device 33 from the ground can be raised by controlling the lifting cylinder 24;

[0055] Step 9: After the operation is completed, the train carriage cleaning device 33 is restored to a non-operating state by one-key control. Steps 1 to 5 can also be started by one-key or manually controlled;

[0056] Step 10. After the car is cleaned, if you need to clean the blind corners and seams inside the car, you can restore the car to the vacuum cleaner state to collect the remaining materials.
