Description

Technical Field

[0001] The invention relates to the technical field of vehicle cleaning automation, and in particular to a concrete mixer truck cleaning device and a cleaning method. Background Art

[0002] Concrete mixer trucks are special vehicles used to transport concrete for construction. Concrete adhered to the surface of the tank during use will not only corrode the steel and paint of the tank, but also scatter on the road surface to cause road pollution. Therefore, the surface of the tank needs to be cleaned in time after each delivery of concrete. With the increasingly stringent domestic environmental protection requirements, it is required not only to clean the tank before leaving the mixing station, but also to clean the tank before leaving the construction site after the concrete is unloaded.

[0003] At present, there is a lack of equipment dedicated to tank cleaning of concrete mixer trucks. Mixing stations and construction sites mostly use simple general vehicle cleaning equipment. This equipment is equipped with a cleaning platform for placing vehicles. The vehicle to be cleaned is parked horizontally on the cleaning platform. The spray gun is moved along the tank body by a handheld spray gun or a mobile frame to clean the surface of the tank body. The wastewater containing concrete particles produced by the cleaning drips from the tank body to the frame and the cleaning platform, and then flows into the sewage treatment equipment. This cleaning device and cleaning equipment have the following problems: (i) The cleaning water of the tank body contains a large amount of concrete particles, which drips onto the chassis of the frame, causing secondary pollution of the chassis and increasing the workload of cleaning the whole vehicle; (ii) The cleaning water falling from the tank body is not recovered in time, resulting in splashing and falling to the ground, which not only pollutes the surrounding environment, but also increases the workload of sewage recovery and treatment.

[0040] In the process of cleaning the tank of a concrete mixer truck with existing vehicle cleaning equipment, the concrete mixer truck is placed in a horizontal state, and the spray gun is moved along the tank body by a handheld spray gun or a mobile frame to clean the surface of the tank body. The sewage containing concrete particles produced by the cleaning drips from the tank body to the frame and the cleaning table, and then converges to the sewage treatment equipment. There is a problem that the cleaning water of the tank body contains a large amount of concrete particles, which drips onto the frame chassis, causing secondary pollution of the frame chassis, and increasing the workload of cleaning the whole vehicle; at the same time, there is a problem that the cleaning water dropped from the tank body is not recovered in time, resulting in splashing and falling to the ground, which not only pollutes the surrounding environment, but also increases the workload of sewage recycling and treatment. In order to solve the above technical problems, the present invention provides a concrete mixer truck cleaning device and provides a method for cleaning the tank body of a concrete mixer truck using the device. The following is a detailed description with reference to the accompanying drawings.

[0041] The concrete mixer truck cleaning device provided by the present invention is described in detail below in conjunction with the accompanying drawings. It should be noted that the specific implementation is only a partial example, not a complete example.

[0042] like Figure 1 and Figure 2 As shown, in the concrete mixer truck cleaning device provided by the present invention, a first parking surface 11 and a second parking surface 12 are arranged at a lateral interval on the upper edge of the table surface of the supporting platform 1, the first parking surface 11 is used to place the first side wheel 53 of the vehicle 5, and the second parking surface 12 is used to place the second side wheel 53 of the vehicle 5.

[0043] like Figure 3As shown, the spray unit includes a spray head 2 and a cleaning water supply mechanism 24. The spray head 2 is arranged on the first lateral side of the supporting platform 1. The front end of the spray head 2 is provided with a spray surface 21 that is adapted to the outer shape of the tank body 51 and arranged obliquely upward. The cleaning water supply mechanism 24 is provided with a water supply pump, and the spray surface 21 is evenly distributed with a plurality of spray ports 22 connected to the water supply pump.

[0044] like Figure 5 As shown, the collecting unit includes a collecting head 3 and a negative pressure collecting mechanism 33. The collecting head 3 is arranged on the second lateral side of the supporting platform 1. The front end of the collecting head 3 is provided with a collecting surface 31 which is adapted to the outer shape of the tank body 51 and arranged obliquely upward. The negative pressure collecting mechanism 33 is provided with a negative pressure vacuum pump, and the collecting surface 31 is provided with a collecting port 32 connected to the negative pressure vacuum pump.

[0045] like Figure 1 and Figure 2 As shown, the carrying platform 1 is connected to the base through a tilting mechanism. Specifically, the second lateral side of the carrying platform 1 is hinged to the base through a lateral hinge, and the first lateral side of the platform is hinged to the base through a support cylinder 17, so that the carrying platform 1 is driven to rotate around the lateral hinge to a tilted state through the extension and contraction of the support cylinder 17. The first lateral side of the carrying platform 1 is provided with an anti-rolling plate 41 for pressing the wheel 53 to prevent the vehicle 5 from tipping over and moving forward and backward in the tilted state, and the outer sides of the first parking surface 11 and the second parking surface 12 are respectively provided with anti-skid baffles 13 for preventing the wheels 53 from sliding sideways. The supporting cylinder 17 drives the carrying platform 1 and the vehicle 5 thereon to tilt sideways to a state where the first lateral side is higher than the second lateral side, so that the cleaning water of the spray head 2 cleans the surface of the rotating tank body 51, and the cleaned concrete is absorbed by the negative pressure of the collecting head 3 together with the cleaning water.

[0046] The provided concrete mixer truck cleaning device works as follows: the supporting platform 1 is driven to a tilting state by a tilting mechanism, the vehicle 5 is tilted laterally to a state where the first lateral side is higher than the second lateral side, the spraying surface 21 of the spray head 2 is obliquely upward toward the first side of the tank body 51, and the collecting surface 31 of the collecting head 3 is obliquely upward toward the second side of the tank body 51; the spraying surface of the spray head is obliquely upward toward the first side of the tank body, and the collecting surface of the collecting head is obliquely upward toward the second side of the tank body; the cleaning water sprayed by the spray head cleans the surface of the rotating tank body, and the sewage generated by the cleaning is collected by the negative pressure of the collecting head. The above process can effectively reduce the cleaning water sprayed on the tank body from dripping onto the frame chassis, thereby reducing the pollution of the frame chassis by the cleaning water. In addition, the sewage is collected before it falls to the ground, which reduces the workload of sewage collection and treatment and improves the cleaning efficiency.

[0047] like Figure 4As shown, in some preferred embodiments, a rear cavity connected to each spray port 22 is provided at the rear end of the spray head 2, a water supply pipe of the water supply mechanism is connected to the rear cavity, a coiled partition is provided at the rear cavity of the spray head 2 to divide the rear cavity into a coiled cavity 23, the water supply pipe is connected to one end of the coiled cavity 23, and each spray port 22 is arranged in an array along the length direction of the coiled cavity 23. When the cleaning water enters the rear cavity, the drainage effect of the coiled cavity makes the spraying amount of each spray port 22 uniform, which is suitable for the structural characteristics of the larger length of the tank body, and the spraying at the front and back is kept uniform, thereby improving the cleaning uniformity.

[0048] After the carrier platform and the vehicle thereon are transformed into an inclined state, the cleaning water of the spray head 2 is sprayed onto the tank body to clean the concrete adhered to the surface of the tank body. The cleaning water sprayed onto the tank body can be carried from the first side of the tank body to the second side as the tank body rotates, so as to be collected by the negative air pressure generated by the collecting head. In some preferred embodiments, a first support rod 15 extending along the length is provided on the first lateral side of the carrier platform 1, and the spray head is connected to the first support rod 15. A first adjustment cylinder for driving the spray head 2 to rotate around the first support rod to adjust the angle of the spray head 2 relative to the tank body 51 is provided between the carrier platform 1 and the spray head 2. During the cleaning process, the spray head and the middle height of the tank body 51 are substantially consistent, and the angle between the spray direction of the spray head and the horizontal plane is adjustable at 5° to 45°. During the spray cleaning process, the height and angle of the spray head are adjusted to keep the cleaning effect of the cleaning water on the tank body in the best state, and to effectively carry the cleaning water and the concrete being cleaned to the other side by the rotation of the tank body.

[0049] like Figure 5 As shown, in some preferred embodiments, the collecting port 32 of the collecting head 3 is configured as cross-extending elongated slits to prevent solid matter in the cleaning water from falling into the slit-like structure and causing blockage, so that the cleaning water can be effectively recovered while the solid matter is retained in the collecting surface. At the same time, the elongated slit can maintain the forward degree of the negative pressure airflow to effectively produce a negative pressure collection effect on the tank surface.

[0050] In some preferred embodiments, a second support rod extending along the length is provided on the second lateral side of the support platform 1, and the collecting head 3 is rotated on the second support rod 16. During the cleaning process, the collecting head 3 is substantially consistent with the bottom height of the tank body 51, and the angle between the collecting direction of the collecting head 3 and the horizontal plane is adjustable at 5° to 60°. A second adjusting cylinder is provided between the base and the collecting head 3 for driving the collecting head 3 to rotate around the second support rod 16 to adjust the angle of the collecting head 3 relative to the tank body 51. The height and angle of the collecting head are adjusted during the spray cleaning process so that the collecting head maintains effective negative pressure collection of the cleaning water of the tank body and the concrete on the surface.

[0051] like Figure 1As shown, an anti-rolling plate 41 for pressing the wheel 53 to prevent the vehicle 5 from tipping over and moving forward and backward when the vehicle 5 is in a tilted state is provided on the first lateral side of the load platform 1. In a specific implementation, in order to improve the anti-tipping capability, the anti-rolling plate 41 includes at least two, one of which cooperates with the front wheel of the vehicle 5 on the load platform 1, and the other anti-rolling plate 41 cooperates with the rear wheel of the vehicle 5 on the load platform 1.

[0052] The middle of the anti-rolling plate 41 is hinged to the supporting platform 1 through a flip cylinder 42, and the rear end of the anti-rolling plate 41 is hinged to the supporting platform 1 through a support plate 43. The flip cylinder 42 and the support plate 43 are arranged laterally with an interval. The anti-rolling plate 41 is driven by the flip cylinder 42 and the support plate 43 to swing inward and press against the wheel 53 of the vehicle 5, and swing outward and away from the wheel 53 of the vehicle 5.

[0053] like Figure 7 , Figure 8 and Fig.11 As shown, a second support portion 45 adapted to the rear end of the anti-rolling plate 41 is provided on the top of the support plate 43. After the anti-rolling plate 41 rotates outward, it is supported and limited by the second support portion 45 and fixed relative to the support plate 43, so that the anti-rolling plate 41 and the support plate 43 are driven to rotate outward and away from the wheel 53 of the vehicle 5 through further extension of the flip cylinder 42.

[0054] like Fig. 9 , Fig.10 , Fig.12 and Fig.13 As shown, a first support portion 44 adapted to the bottom surface of the anti-rolling plate 41 is provided on the top of the support plate 43. After the anti-rolling plate 41 is flipped inward, it is supported and limited by the first support portion 44 and fixed relative to the support plate 43, so that the anti-rolling plate 41 and the support plate 43 are driven to rotate inward and pressed against the wheel 53 of the vehicle 5 through further contraction of the flip cylinder 42.

[0055] The present invention provides a method for cleaning a concrete mixer truck. A vehicle 5 to be cleaned drives onto a carrying platform 1.

[0056] like Fig.14 As shown, the support platform 1 is driven by the tilting mechanism to change from a horizontal state to a tilted state, the vehicle 5 is tilted laterally to a state where the first lateral side is higher than the second lateral side, the spraying surface 21 of the spray head 2 is obliquely upward toward the first side of the tank body 51, and the collecting surface 31 of the collecting head 3 is obliquely upward toward the second side of the tank body 51;

[0057] like Fig.15As shown, the vehicle 5 drives the tank body 51 to rotate in the direction of the first lateral side → the top surface of the tank body 51 → the second lateral side of the tank body 51, and the cleaning water sprayed by the spray head 2 is sprayed to the first lateral side of the tank body 51 to clean the surface of the rotating tank body 51, and the cleaning water is carried to the second lateral side by the rotation of the tank body 51, and the negative pressure airflow generated by the collection head 3 collects the cleaning water and the concrete under cleaning;

[0058] After cleaning, the support platform 1 is driven by the tilting driving mechanism to change from the tilted state to the horizontal state;

[0059] The vehicle 5 that has been cleaned drives out of the carrying platform 1 .

[0060] The concrete mixer truck cleaning device provided by the present invention, during the tank cleaning process, adjusts the vehicle to a state where the height of the first lateral side is higher than the height of the second lateral side through the support platform, the spraying surface of the spray head is inclined upward toward the first side of the tank body, and the collecting surface of the collecting head is inclined upward toward the second side of the tank body; the cleaning water sprayed by the spray head cleans the rotating tank surface, and the sewage generated by the cleaning is collected by the negative pressure of the collecting head, which effectively reduces the cleaning water sprayed on the tank body from dripping onto the frame chassis, reduces the pollution of the frame chassis by the cleaning water, and the sewage is collected before it falls to the ground, which reduces the workload of sewage collection and treatment, and improves the cleaning efficiency. The device has a simple structure and is easy to operate, and is suitable for use in mixing stations and construction sites.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
