Description

Technical Field

[0001] The invention relates to the field of material cleaning and processing equipment, and in particular to a cleaning device which can automatically adapt to a carriage. Background Art

[0002] Ports, power plants, mining and smelting companies purchase a large amount of block or powdered mineral resources as raw materials, such as coal, during the production process. After purchasing these bulk raw materials in bulk, they are mainly transported by train or heavy truck. During transportation, due to moisture and vibration, the bulk materials will generally adhere tightly to the carriage. After unloading, some of the materials cannot be unloaded cleanly, and generally adhere to the bottom or side walls of the carriage, requiring manual cleaning. Moreover, there are many types of models. There are dozens of models of open train carriages that transport more bulk materials, and the length, width and height of each model are also different. Therefore, a cleaning device that can be used for a variety of carriage sizes is needed to replace manual automatic cleaning operations. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a carriage residual material cleaning and collecting device that can automatically adapt to carriages of different widths to complete the cleaning work of carriages of different widths.

[0004] The technical solution adopted in the embodiment of the present invention is: a cleaning device that can automatically adapt to the carriage, comprising:

[0005] Lifting mechanism, used for lifting with external lifting equipment;

[0006] A mounting frame, wherein the mounting frame is connected to a lifting mechanism above via a first lifting mechanism;

[0007] At least two side wall cleaning mechanisms, the two side wall cleaning mechanisms are respectively arranged on the left and right sides of the mounting frame, the side wall cleaning mechanism comprises a vertical brush, a vertical brush frame and a vertical brush driving device, the vertical brush is vertically rotatably connected to the outside of the vertical brush frame, the vertical brush driving device is transmission-connected to the vertical brush to drive the vertical brush to rotate, and the vertical brush frame is vertically rotatably connected to the side of the mounting frame;

[0008] A synchronous retracting mechanism, wherein the synchronous retracting mechanism is connected between the two vertical brush frames, and the synchronous retracting mechanism drives the two vertical brush frames to rotate inward as the mounting frame moves away from the lifting mechanism;

[0009] The return device is connected to the vertical brush frame to pull the vertical brush frame to rotate outward.

[0010] The cleaning device capable of automatically adapting to the carriage according to the embodiment of the present invention has at least the following beneficial effects:

[0011] When the carriage needs to be cleaned, the external lifting equipment lifts the lifting mechanism. Due to the gravity of the equipment itself, the first lifting mechanism between the mounting frame and the lifting mechanism is stretched, and the height of the entire cleaning device reaches the maximum. As the distance between the mounting frame and the lifting mechanism increases, the synchronous retraction mechanism drives the two vertical brush frames to rotate inward and retract, and the distance between the two vertical brush frames is gradually reduced to the minimum, obtaining a smaller insertion width, so that the cleaning device can be placed in carriages of different widths.

[0012] When the cleaning device is placed in the carriage, the bottom of the mounting frame first contacts the bottom of the carriage, and the cleaning device is then lowered. The first lifting mechanism begins to rise and shorten, and the distance between the mounting frame and the lifting mechanism decreases. Subsequently, the synchronous retraction mechanism begins to remove the force on the two vertical brush racks. Subsequently, the two vertical brush racks are pulled outward by the return device, and the distance between the two vertical brush racks gradually increases and opens until the vertical brush contacts the side wall of the carriage, thereby achieving the purpose of the cleaning device adapting to the width of the carriage. The present application can automatically adapt to the width of different carriages by its own gravity to meet the cleaning needs of different carriages, and does not require additional power drive to adapt to the width of the carriage.

[0048] Reference Figures 1 to 4 As shown, the cleaning device that can automatically adapt to the carriage includes:

[0049] The lifting mechanism 100 is used for lifting by an external lifting device. In this embodiment, the lifting mechanism 100 is an upper frame, and a lifting hole 110 is provided on the upper frame;

[0050] A mounting frame 300, the mounting frame 300 is connected to the upper lifting mechanism 100 through a first lifting mechanism;

[0051] At least two side wall cleaning mechanisms 600, the side wall cleaning mechanisms 600 are respectively arranged on the left and right sides of the mounting frame 300, the side wall cleaning mechanisms 600 include a vertical brush 610, a vertical brush frame 620 and a vertical brush driving device 630, the vertical brush driving device 630 and the vertical brush 610 are transmission-connected to drive the vertical brush 610 to rotate, the vertical brush 610 is vertically rotatably connected to the outer side of the vertical brush frame 620, and the vertical brush frame 620 is vertically rotatably connected to the side of the mounting frame 300;

[0052] A synchronous retracting mechanism 800, which is connected between the two brush holders 620. As the mounting frame 300 and the lifting mechanism 100 move away from each other, the synchronous retracting mechanism 800 drives the two brush holders 620 to rotate inwards;

[0053] The return device 700 is connected to the vertical brush frame 620 to pull the vertical brush frame 620 to rotate outward.

[0054] like Figure 1 As shown, when the carriage needs to be cleaned, the external lifting equipment lifts the lifting mechanism 100 through the lifting hole 110. Under the action of its own gravity, the first lifting mechanism between the mounting frame 300 and the lifting mechanism 100 is stretched, and the height of the entire cleaning device reaches the maximum. As the distance between the mounting frame 300 and the lifting mechanism 100 increases, the synchronous retraction mechanism 800 drives the two vertical brush racks 620 to rotate inward and retract, and the distance between the two vertical brush racks 620 is gradually reduced to the minimum, obtaining a smaller insertion width, so that the cleaning device can be placed in carriages of different widths;

[0055] like Figure 2 As shown, after the cleaning device is placed in the carriage, the mounting frame 300 first contacts the bottom of the carriage, and at this time, the cleaning device continues to be lowered, the first lifting mechanism begins to shorten, and the distance between the mounting frame 300 and the lifting mechanism 100 decreases, and then the synchronous retracting mechanism 800 begins to remove the force on the two vertical brush frames 620. Subsequently, the two vertical brush frames 620 are pulled outward by the return device 700, and the distance between the two vertical brush frames 620 gradually increases and opens until the vertical brush 610 contacts the side wall of the carriage, thereby achieving the purpose of the cleaning device adapting to the width of the carriage.

[0056] At this time, the two vertical brushes 610 are in contact with the side walls of the carriage and can start to clean the side walls of the carriage. Driven by related equipment, the cleaning device moves back and forth in the carriage to clean the carriage.

[0057] The cleaning device of the present application can automatically adapt to the width of different carriages by relying on its own gravity to meet the cleaning needs of different carriages. It does not require additional power drive to adapt to the width of the carriage, and can complete the cleaning of the bottom of the vehicle and the walls of the carriage at the same time.

[0058] like Figures 1 to 3 As shown, a carriage positioning mechanism 200 is provided between the lifting mechanism 100 and the mounting frame 300, and the carriage positioning mechanism 200 includes a positioning mechanism frame 210, a left positioning device 220, a right positioning device 230 and a telescopic connecting rod mechanism 240;

[0059] The positioning mechanism frame 210 and the lifting mechanism 100 are connected via a telescopic guide shaft 120, which is composed of a lifting mechanism guide sleeve connected to the lifting mechanism 100 and a positioning frame guide sleeve connected to the positioning mechanism frame 210, so that the telescopic guide shaft 120 can be telescoped up and down;

[0060] The positioning frame 210 and the mounting frame 300 are connected via a second lifting mechanism 400, which is composed of a lifting rod connected to the mounting frame 300 and a positioning frame guide sleeve:

[0061] The left positioning device 220 and the right positioning device 230 each include a positioning wheel mounting plate 221, a top positioning wheel 222 and a side wall positioning wheel 223. The left positioning device 220 and the right positioning device 230 are symmetrically arranged. The middle parts of the two positioning wheel mounting plates 221 are rotationally connected to the left and right sides of the positioning mechanism frame 210 through a rotating shaft 250. The top positioning wheel 222 and the side wall positioning wheel 223 are both rollingly connected to the positioning wheel mounting plate 221. The rolling surfaces of the top positioning wheel 222 and the side wall positioning wheel 223 correspond to the top and side wall of the carriage respectively.

[0062] The telescopic link mechanism 240 is connected to the positioning mechanism frame 210 , and the telescopic link mechanism 240 is connected to the two positioning wheel mounting plates 221 to drive the positioning wheel mounting plates 221 to rotate around the rotating shaft 250 . A first pull rope 260 is provided between the telescopic link mechanism 240 and the lifting mechanism 100 .

[0063] When the cleaning device is lifted, the guide shaft 120 between the positioning mechanism frame 210 and the lifting mechanism 100 is extended, the positioning mechanism frame 210 moves downward, and the first pull rope 260 provided between the telescopic link mechanism 240 and the lifting mechanism 100 begins to be subjected to force, opening the telescopic link mechanism 240 to a certain angle. This angle facilitates the top positioning wheel 222 and the side wall positioning wheel 223 to fall onto the top and side wall of the car wall.

[0064] When the cleaning device is placed in the carriage, as the height of the entire cleaning device decreases, the top positioning wheel 222 will first contact the top of the carriage. After the top positioning wheel 222 contacts the top of the carriage, the distance between the positioning mechanism frame 210 and the lifting mechanism 100 gradually decreases, and the first pull rope 260 loses its tension and becomes loose. Under the support force of the side wall of the carriage, the top positioning wheel 222 pushes the positioning wheel mounting plate 221 to rotate around the rotating shaft 250, and finally makes the wall positioning wheel 223 contact and press against the side wall of the carriage. At the same time, the top positioning wheel and the side wall positioning wheel symmetrically arranged on the other side of the carriage also contact the other side wall of the carriage at the same time, and make the center of the cleaning device coincide with the center of the carriage. The cleaning mechanism can be provided with multiple sets of carriage positioning wheels.

[0065] Finally, when cleaning, external equipment does not need to bear the gravity of the cleaning device, and the gravity of the cleaning device acts completely on the carriage. Under the action of gravity, the carriage positioning mechanism 200 can make the cleaning device attached to the carriage, and the top positioning wheel 222 and the side wall positioning wheel 223 of the positioning mechanism can move back and forth with the two side walls of the carriage as guide rails, and can keep the center of the cleaning device completely coincident with the center of the carriage during movement.

[0066] During cleaning, the cleaning device can be dragged by an external device to move back and forth along the length direction of the carriage, or the cleaning device can be driven by its own power to move back and forth along the carriage for cleaning. In this embodiment, a cleaning device driving device is provided, and the cleaning device driving device is connected to the top positioning wheel 222 and / or the side wall positioning wheel 223 in a transmission manner to drive the top positioning wheel 222 and the side wall positioning wheel 223 to move along the length direction of the carriage.

[0067] The bottom of the mounting frame 300 is provided with a vehicle bottom cleaning mechanism 500, which includes a horizontal brush and a horizontal brush driving motor for driving the horizontal brush to rotate, and the horizontal brush is horizontally arranged at the bottom of the mounting frame 300. When the horizontal brush contacts the bottom of the carriage, the bottom of the carriage can be cleaned when walking in the carriage.

[0068] When the cleaning device moves to one end of the car, the external equipment lifts the cleaning device upwards. At this time, the vertical brushes 610 on both sides cannot clean the side walls at the end of the car. At this time, the cleaning device needs to be repeatedly lifted and lowered by the lifting device, and the side walls at the end of the car need to be cleaned by the horizontal brush.

[0069] Furthermore, the mounting frame 300 includes a telescopic frame 310 and a structural frame 320 which are arranged up and down. The telescopic frame 310 is connected to the positioning mechanism frame 210 through the second lifting mechanism 400 , and the structural frame 320 is connected below the telescopic frame 310 through the rotating mechanism 330 .

[0070] In this embodiment, the second lifting mechanism 400 is connected by a lifting rod and a guide shaft sleeve, and the two can slide and retract up and down to achieve the purpose of lifting.

[0071] Due to the structural design of the present application, only one side of the horizontal brush can clean the end surface of the carriage (reference Figure 4 When the two vertical brushes retract, there will be a groove surface between the two vertical brushes, which will interfere with the cleaning of the horizontal brush). Only the back side can be cleaned. Therefore, when it is necessary to clean the other end face, the entire cleaning device needs to be lifted up by a lifting device, and then the cleaning device is turned as a whole.

[0072] In order to solve this problem, this embodiment connects the telescopic frame 310 and the structural frame 320 through a rotating mechanism 330. After cleaning one end surface, it is only necessary to rotate the rotating mechanism to drive the structural frame 320 to rotate 180° to clean the other end surface, thereby eliminating the need to turn the entire cleaning device, thereby improving the cleaning efficiency.

[0073] The synchronous retraction mechanism 800 includes a second pull rope 810, a transmission member 820 and two connecting rods 830. The transmission member can be rotatably connected to the structural frame 320. The two sides of the transmission member are respectively connected to the vertical brush frame 620 through the connecting rods 830. One end of the second pull rope 810 is connected to the transmission member, and the other end is connected to the positioning mechanism frame 210. The two connecting rods 830 retract inward as the transmission member rotates.

[0074] When lifting, as the mounting frame 300 moves downward, the distance between the mounting frame 300 and the positioning mechanism frame 210 gradually increases, and the second pull rope 810 will pull the transmission member to rotate. As the transmission member rotates, the connecting rods 830 on both sides retract inward, pulling the vertical brush holder 620 to rotate inward, thereby reducing the distance between the two vertical brush holders 620 to facilitate placement into the car.

[0075] Preferably, the transmission member 820 is a triangle, the middle part of the bottom side of the triangle can be rotatably connected to the structural frame 320, the two ends of the bottom side of the triangle are respectively connected to the vertical brush frame 620 through the connecting rod 830, one end of the second pull rope 810 is connected to the triangle, and the other end is connected to the positioning mechanism frame 210.

[0076] In this embodiment, a triangle is preferably used as the transmission member 820, but other shapes, such as a circle, may also be used as long as the two connecting rods 830 can be retracted inwardly as the transmission member 820 rotates.

[0077] The return device 700 is an elastic member, such as a spring, a rubber strip, etc., and is preferably a return spring in the present application. One end of the elastic member is connected to the vertical brush holder 620, and the other end is connected to the structural frame 320 to pull the vertical brush holder 620 to rotate outward.

[0078] When the cleaning device is placed in the carriage, as the mounting frame 300 and the positioning mechanism frame 210 gradually decrease, the triangle will lose the tension of the second pull rope 810. At this time, the vertical brush frame 620 will rotate outward under the action of the return spring until the vertical brush 610 on the vertical brush frame 620 contacts the side wall of the carriage, so that the cleaning device can clean the two side walls.

[0079] Further, a disc-shaped bottom disc brush 611 is provided at the bottom of the vertical brush 610. By providing the disc brush 611, the position between the vertical brush 610 and the horizontal brush, that is, the angle between the bottom of the vehicle and the carriage, can be cleaned, thereby improving the cleaning quality.

[0080] The embodiment of the present invention further provides a negative pressure suction mechanism for sucking the cleaned particles. During the cleaning operation, the negative pressure suction mechanism is connected to an external negative pressure suction device to transport the cleaned residual materials to the outside of the carriage.

[0081] The negative pressure suction mechanism includes a suction pipe 900 and a suction nozzle, which is connected to the suction pipe 900, and the opening of the suction nozzle faces the horizontal brush. The suction pipe 900 is connected to the external negative pressure suction device, and each vertical brush 610 rotates toward the middle during cleaning, so that the remaining material on the vehicle wall falls to the middle of the cleaning device, and then passes through the horizontal brush and is swept to the vicinity of the suction nozzle to be sucked away. In this way, no matter which direction the cleaning device moves, the rotation direction of the vertical brush 610 does not need to be changed.

[0082] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
