[0050] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0051] Embodiment 1

[0052] like Figures 1 to 8 As shown, an embodiment of the present invention provides a cleaning device, which is composed of a cleaning device 1, a telescopic device 2, an operating device 3, etc.

[0053] The cleaning device 1 has a nozzle 12 for spraying fluid and an air nozzle 11 for spraying air flow and forming a sealing knife.

[0054] The telescopic device 2 has a telescopic component 21 connected to the cleaning device 1 at one end, and is used to make the cleaning device 1 reciprocate along the telescopic direction of the telescopic component 21 .

[0055] The operating device 3 has a supporting platform 31 connected to the other end of the telescopic component 21, an air supply device 32 connected to the air nozzle, a fluid conveying device 33 connected to the nozzle 12, and a control device 39 electrically connected to the air supply device 32 and the fluid conveying device 33.

[0056] It can be known from the above contents that: in this embodiment, the cleaning device 1 is moved to a position of a to-be-cleaned area adjacent to the object to be cleaned, such as the body 5 of a mining transport vehicle, by the telescopic device 2 in the cleaning equipment, and the fluid conveying device 33 is controlled by the operating device 3 so that the nozzle 12 performs high-pressure flushing on the area to be cleaned, such as the inner wall 51 of the body 5, and then the air supply device 32 is controlled so that the air nozzle 11 sprays a high-pressure airflow on the area after high-pressure flushing to form a sealing knife, and then the telescopic component 21 is extended or contracted so that the sealing knife moves back and forth along the telescopic direction, and the residue on the area to be cleaned, such as Figure 6 and Figure 7 The powder attached to the inner wall 51 of the compartment 5 shown in the figure is scraped off to facilitate cleaning and recycling.

[0057] Therefore, through the cooperation among the cleaning device 1, the telescopic device 2 and the operating device 3 in the cleaning equipment, especially the cooperation among the nozzle 12, the air nozzle 11 and the telescopic assembly 21, the residual powder on the inner wall 51 of the box body 5, especially the powder that is hardened and adhered, can be conveniently cleaned. In addition, through the telescopic assembly 21, the nozzle 12 and the air nozzle 11 can be very conveniently used to clean the inner wall 51 of the box body 5 in a large area, thereby facilitating the cleaning and recovery of the powder, improving the cleaning efficiency and reducing the labor cost.

[0058] In addition, the airflow sprayed through the air nozzle 11 can help to clean the area to be cleaned and dry it at the same time.

[0059] Specifically, Figure 1 and Figure 2 As shown, the cleaning device 1 in this embodiment is mainly composed of a cleaning bracket 13 for fixing the air nozzle 11 and the nozzle 12, and the air nozzle 11 and the nozzle 12 arranged along the circumference of the cleaning bracket 13. Through this arrangement structure, when the cleaning device 1 reciprocates along the telescopic direction, the air nozzle 11 and the nozzle 12 arranged on the cleaning bracket 13 can quickly clean the inner wall 51 of the compartment 5 from different directions, forming a three-dimensional cleaning, and different side walls inside the compartment 5 can be cleaned at the same position, thereby expanding the cleaning range and greatly improving the cleaning efficiency.

[0060] Furthermore, if Figure 4 As shown, the cleaning device 1 in this embodiment further includes: a limiting wheel 14 arranged along the circumference of the cleaning bracket 13, which is used to slide the cleaning bracket 13 along the telescopic direction. The limiting wheel 14 can facilitate the movement of the cleaning bracket 13 while maintaining a set distance between the cleaning bracket and the object to be cleaned, such as the inner wall 51 of the compartment 5, to prevent the air nozzle 11 and the nozzle 12 from being damaged due to collision.

[0061] Further preferably, Figure 1 and Figure 2 As shown, in order to meet the design and use requirements in practical applications and facilitate the synchronous cleaning of the side walls in the body 5 of the mining transport vehicle, the cleaning bracket 13 can be composed of a bracket frame 131 connected to one end of the telescopic component 21. Among them, at least three sides 1311 of the bracket frame 131 are each provided with a tuyere 11 and a plurality of nozzles 12; wherein a first angle is formed between the spray direction of the tuyere 11 and the telescopic direction; a second angle is formed between the spray direction of the nozzle 12 and the telescopic direction; the first angle is 60° to 120°; and the second angle is 60° to 120°. Moreover, the first angle in this embodiment is preferably 90°; and the second angle is preferably 60°.

[0062] Further preferably, Figure 1 and Figure 2 As shown, in order to ensure the installation of the nozzle 12 and prevent it from being damaged due to collision when moving with the bracket frame 131, the cleaning bracket 13 of this embodiment further includes: a baffle 132 arranged on the bracket frame 131, and the baffle 132 and the telescopic assembly are respectively located on opposite sides of the bracket frame 131; wherein, an installation groove for arranging the nozzle 12 is formed between the bracket frame 131 and the baffle 132. In addition, the side edges 1311 where the nozzle 12 is arranged are also provided with limiting wheels 14.

[0063] Further preferably, in order to facilitate the cleaning of the cleaning device, as Figure 1As shown, in this embodiment, the side edges 1311 on the opposite sides and the side edge at the bottom of the support frame 131 are each provided with an air nozzle 11 and a plurality of nozzles 12 .

[0064] Further preferably, the nozzles 12 located on the same side are arranged equidistantly; and the number of the nozzles arranged on each side is five.

[0065] In addition, it should be noted that the cleaning bracket 13 in this embodiment is not limited to the bracket frame 131, and can also be a frame of other shapes, such as a circular or elliptical bracket body.

[0066] Further preferably, Figure 3 As shown, the nozzle 11 includes: a flexible bag body 112 having an opening 111 and being flat when no gas is sprayed; wherein, when the nozzle 11 sprays airflow, the flexible bag body 112 forms a blade portion 1121 of a sealing knife at a position where the flexible bag body 112 is in linear contact with the area to be cleaned. When the flexible bag body sprays airflow, it can expand under the impact of the airflow to form a flexible body that can spray airflow along the opening 111, i.e., a sealing knife, so that when the cleaning bracket 13 approaches the inner wall 51 of the compartment 5, the sealing knife contacts the inner wall 51 of the compartment 5, and forms a blade portion 1121 at a position where linear contact is formed, so that while the airflow is sprayed through the opening, the powder attached to the inner wall 51 can be scraped off by the physical action of the blade portion 1121, and it is not easy to cause physical damage to the area to be cleaned. In addition, the blade portion 1121 of the sealing knife formed by the flexible bag body 112 can fit well with the area to be cleaned, avoiding the phenomenon that the cleaning area is uneven and a local area cannot be cleaned due to a gap between the blade portion 1121 and the cleaning area.

[0067] Here, it is worth mentioning that the opening 111 in this embodiment can preferably be a thin slit, the length of which can be 1 m, and the width can be appropriately designed and adjusted according to the pressure and flow rate of the gas.

[0068] Further preferably, Figure 3 As shown, the flexible bag body 112 in this embodiment is connected to the support frame 131 and one end connected to the air supply device 32 is a closed end 113; and the closed end 113 is connected to the side edge 1311 and arranged along its length direction, so that the blade portions 1121 formed by two adjacent air nozzles 11 can be connected to each other. Therefore, the length of the flexible bag body 112 is controlled by the length of the side edge 1311 of the support frame 131, and the length of the blade portion 1121 of the flexible bag body 112 after the sealing knife is formed is increased to expand the cleaning range and realize the connection between the blade portions 1121 of the two adjacent sealing knives.

[0069] Furthermore, the width of the flexible bag body 112 gradually increases from the closed end 113 to the end with the opening 111, so that after the airflow is introduced into the closed end 113 of the flexible bag body 112, it diffuses from the closed end 113 to the end with the opening 111, so as to expand the area of ​​the sprayed airflow while avoiding excessive expansion of the flexible bag body 112 so that the sealing knife cannot maintain a good shape, which is not conducive to scraping off the powder attached to the inner wall 51.

[0070] like Figure 1 and Figure 2 As shown, the telescopic assembly 21 can be composed of a foldable connecting rod assembly 211, etc., which are respectively connected to the cleaning device 1 and the support platform 31 at opposite ends. In addition, the connecting rod assembly can be composed of a plurality of connecting rod units 2111, etc., which are connected end to end and arranged along the telescopic direction. Among them, two adjacent connecting rod units 2111 are pivotally connected to each other. Under the action of external force, such as manpower or driving force, the connecting rod units 2111 can be synchronously folded or unfolded by the telescopic assembly 21 to drive the reciprocating motion of the cleaning device 1.

[0071] Further preferably, Figure 1 and Figure 2 As shown, in order to ensure that the cleaning device 21 moves smoothly along the telescopic direction, the connecting rod unit 2111 in this embodiment can be composed of a group of first connecting rods 2111a and second connecting rods 2111b that are mutually crossed and pivotally connected. And the telescopic assembly 21 can be composed of at least two groups of connecting rod assemblies 211 that are parallel to each other, and a plurality of pivot shafts 212 that are mutually parallel and opposite to each other and are respectively pivotally connected to each connecting assembly. Obviously, the connecting rod unit 2111 in this embodiment can be composed of more than two groups of first connecting rods 2111a and second connecting rods 2111b that are mutually crossed and pivotally connected. Here, no further description and specific explanation are given.

[0072] Further preferably, Figure 1 and Figure 8 As shown, the air supply device 32 can be composed of an air supply pipe 321 connected to the air nozzle 11, a fan 322 arranged on a supporting platform and connected to the air supply pipe 321, etc. Among them, the air supply pipe 32 passes through each pivot shaft 212 in the telescopic assembly in sequence from one end connected to the air nozzle 11 along the telescopic direction and is connected. For example, by binding parts such as cable ties and fasteners, each section of the air supply pipe 32 is connected to the corresponding pivot shaft 212, and then connected to the fan 322 (the fan 322 in this embodiment is preferably a high-pressure fan). Each pivot shaft 212 in the telescopic assembly 21 can be used to connect the two relatively arranged connecting rod units 2111 respectively, and at the same time, the air supply pipe 32 can be accommodated and fixed, so that the air supply pipe 32 can be extended and contracted synchronously with the extension and contraction of the telescopic assembly 21.

Each pivot shaft 212 in the telescopic assembly 21 can respectively connect the two relatively arranged connecting rod units 2111 and play the role of accommodating and fixing the fluid delivery pipe 331, so that the fluid delivery pipe 331 can be extended and contracted synchronously with the extension and contraction of the telescopic assembly 21.

[0074] Further preferably, Figure 1 and Figure 4 As shown, the operating device 3 includes: a base 35 with a pulley 30 at the bottom, a frame 36 arranged on the base 35, a support platform 31 slidably arranged on the frame 36, a support rod 37 connected to the support platform 31, and a first drive cylinder 38 arranged on the base 35; wherein, when the support rod 37 is driven by the first drive cylinder 38 to perform telescopic movement, it drives the support platform 31 to perform lifting and lowering movement in a direction perpendicular to the telescopic direction. The pulley 30 under the base 35 can facilitate the movement of the cleaning device 1, and at the same time, with the help of the first drive cylinder 38, the support platform 31 can be moved to a preset height position under the action of the support rod 37, so as to facilitate the cleaning device 1 to be lifted to the opening area of ​​the compartment 5, so as to facilitate the subsequent cleaning operation. In addition, the base 35 can also be used to place the control device 39 to facilitate the operation of the staff. Here, it should be noted that the first drive cylinder 38 in this embodiment can be designed as a drive motor, a drive cylinder or a drive cylinder according to actual needs.

The telescopic assembly 21 is driven by the driving rod 342 to realize automatic extension and contraction of the telescopic assembly 21. Here, it should be noted that the second driving cylinder 341 in this embodiment can be designed as a driving motor, a driving cylinder or a driving oil cylinder according to actual needs.

[0076] Further preferably, Figure 1 and Figure 4 As shown, in order to facilitate the assembly and connection between the telescopic assembly 21 and the frame 36, and not to affect the telescopic movement of the telescopic assembly 21, the frame 36 in this embodiment can be composed of a frame body 362 vertically connected to the base 35 and provided with a hollow area 361.

Among them, the end of the telescopic component 21 connected to the frame body 362 is provided with a sliding wheel 216 for inserting into the slide groove 1313 through the pivot shaft 212 to form a sliding connection. Obviously, the telescopic component 21 in this embodiment can also be directly connected to the bracket frame 131 through the pivot shaft 212, so as to directly promote the movement of the cleaning device 1 when the telescopic component 21 is extended.

[0078] In addition, as a further preferred mode, the base 35 in this embodiment can be composed of a base body 351, a rotating body 352 rotatably arranged on the base body 351 and used to arrange the frame body 362 and the control device 39, etc. By rotating the base body 351, the direction of the telescopic assembly 21 and the cleaning device 1 can be conveniently adjusted to facilitate operation.

[0079] In addition, the air nozzle 11 in this embodiment can be an independently arranged air nozzle, that is, a component having an independent air jet, and can also be connected to an external fan through a corresponding air supply pipe to achieve the function of jetting air. The nozzle 12 in this embodiment can be an independently arranged nozzle, that is, a component having an independent fluid jet, and can also be connected to an external injection water pump through a corresponding fluid delivery pipe to achieve the function of jetting fluid.

[0080] In addition, it is worth mentioning that the cleaning device 1 in this embodiment is also provided with a sensor 101 electrically connected to the control device 39, which is used to enable the control device to control the telescopic length of the telescopic device. Figure 3 As shown, the sensor 101 may be a photoelectric sensor disposed at the front end of the bracket frame 131 of the cleaning bracket 13, such as a distance sensor, so that the control device can control the extension and retraction of the telescopic assembly according to the distance detected by the sensor 101. Obviously, the sensor 101 of this embodiment is not limited to the above-mentioned sensor, and may also be other types of sensors, and may be disposed at other positions to achieve the purpose of automatically controlling the extension and retraction of the telescopic device, which will not be described in detail here.

After that, through the extension or contraction of the telescopic component 21, the sealing knife can reciprocate along the telescopic direction.

[0090] Step S3: The control device 39 controls the nozzle 11 in the cleaning device 1 to spray airflow to the side wall of the compartment 5, and forms a sealing knife in contact with the side wall, and at the same time, the cleaning device 1 is returned from the second position to the first position by contracting the telescopic component 21, so that the blade 1121 of the sealing knife scrapes the side wall. The pressure value of the airflow is greater than 0.55 MPa.

[0091] Through the above steps, the extension of the telescopic component 21 can be synchronized with the injection of fluid from the nozzle 12, so that the cleaning device 1 can move from the first position to the second position, and the powder attached to the inner wall 51 of the compartment 5 in the area between the first position and the second position can be subjected to preliminary treatments such as impact and wetting, and then the contraction of the telescopic component 21 is synchronized with the injection of air flow from the nozzle 11, so that in the process of the cleaning device 1 returning from the second position to the first position, with the help of the sealing knife, the powder remaining on the inner wall 51 of the compartment 5 in the area between the first position and the second position can be scraped off, and under the action of the sealing knife, the scraped powder can be pushed to the first position, such as the opening area of ​​the compartment 5, to facilitate cleaning and recycling, thereby improving the cleaning efficiency.

[0092] In addition, it is worth mentioning that the flow rate of the gas sprayed from the nozzle 11 in this embodiment can be preferably 300m / s, so as to match the nozzle 11 to reach the corresponding pressure value and improve the cleaning efficiency.

[0093] Specifically, in this embodiment, after the step of moving the cleaning device 1 to the area to be cleaned inside the mining transport vehicle by telescoping the telescopic assembly 21, the following steps are further included:

[0094] Step S0: The first driving cylinder 38 is controlled by the operating device 3 so that the support rod 37 performs telescopic movement, thereby driving the support platform 31 to rise and fall to a preset height position, and allowing the cleaning device 1 to be located in the opening area of ​​the compartment 5.
