Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] See Figure 1-6 An automatic flushing machine for fully mechanized hydraulic supports includes a base 1, a U-shaped mounting frame 2 with an opening facing one side on the base 1, a track between the two sides of the mounting frame 2 on the base 1, and an electric railcar 3 that travels along the length of the track above the track. The electric railcar 3 is a railcar with a track platform in the prior art. The hydraulic support can be placed on the railcar. Lifting mechanisms 4 are respectively provided on three surfaces of the mounting frame 2. The three lifting mechanisms 4 are respectively provided with displacement mechanisms 5 that move along the width of the mounting frame 2. The displacement mechanisms 5 are provided with a rotating mechanism 6 that can rotate along the horizontal direction of the mounting frame 2. The rotating mechanism 6 is provided with an angle adjustment mechanism 7 that can tilt along the inner side of the mounting frame 2. The angle adjustment mechanism 7 is provided with a telescopic mechanism 8 that can reciprocate towards the inner side of the mounting frame 2. A high-pressure flushing gun 9 with its nozzle facing the inner side of the mounting frame 2 is connected to the telescopic mechanism 8. The high-pressure flushing gun 9 is connected to a water pump spray pipe. The electric railcar 3, lifting mechanisms 4, displacement mechanisms 5, rotating mechanisms 6, angle adjustment mechanisms 7, and telescopic mechanisms 8 are respectively connected to a controller.

[0026] The lifting mechanism 4 includes a stepper motor 401, a rotating screw 402, a screw sleeve 403, and a lifting rod 404. Stepper motors 401 are respectively installed on the top of both sides of the three sides of the mounting frame 2. The stepper motors 401 are detachably installed on the top of the mounting frame 2. The output ends of the two stepper motors 401 are vertically connected to the rotating screws 402. The two ends of the rotating screws 402 are rotatably connected to the top of the mounting frame 2 and the base 1, respectively. Screw sleeves 403 are fitted on the two rotating screws 402. The screw sleeves 403 are rectangular. The lifting rod 404 is horizontally installed between the two screw sleeves 403. The stepper motors 401 are connected to the controller. The displacement mechanism 5 is installed on the lifting rod 404. In use, the stepper motors 401 are controlled by the controller to work, which causes the two rotating screws 402 to rotate, thereby driving the two screw sleeves 403 to rotate, and further driving the lifting rod 404 to move up or down, thereby adjusting the height of the high-pressure washing gun 9 and achieving a more comprehensive cleaning range.

[0027] The displacement mechanism 5 includes a U-shaped displacement plate 501, a limiting slider 502, a first bearing 503, a first rack 504, a first gear 505, and a displacement motor 506. The displacement plate 501 is mounted on the lifting rod 404 with its opening facing downwards. Two limiting sliders 502 are respectively disposed on the two inner walls of the displacement plate 501 and abut against the two sides of the lifting rod 404, effectively ensuring that the displacement plate 501 can shift. The first bearing 503 is disposed on the upper surface of the lifting rod 404 and horizontally connected between the two sides of the displacement plate 501 by a pin. The first rack 504 is disposed on the lower surface of the lifting rod 404 and extends along its length. The displacement motor 506 is set on the outer surface of one side of the displacement plate 501, and its output end passes through the side wall of the displacement plate 501. The first gear 505 is sleeved on the output shaft of the displacement motor 506 and meshes with the first rack 504. The displacement motor 506 is electrically connected to the controller. The rotating mechanism 6 is set on the top of the displacement plate 501. When in use, the controller controls the displacement motor 506 to work, which drives the first gear 505 to rotate, thereby causing the displacement plate 501 to move along the length direction of the lifting rod 404, so as to achieve the purpose of horizontal displacement of the high-pressure washing gun 9, thereby achieving a more comprehensive cleaning range.

[0028] The preferred lifting rod 404 has a square structure.

[0029] The preferred mounting bracket 2 has bearing seats 405 horizontally mounted on its top and on the base 1 directly below it, and the two ends of the rotating screw 402 are rotatably connected to the bearing seats 405 respectively.

[0030] The displacement mechanism 5 also includes two second bearings 507, which are horizontally mounted on opposite side walls of the displacement plate 501 via pins. The two second bearings 507 are located on the lower surfaces of the lifting rods 404 on both sides of the first gear 505. The arrangement of the two second bearings 507 facilitates the stability of the displacement plate 501 during its movement.

[0031] The rotating mechanism 6 includes a first motor base 601 and a rotating motor 602. The first motor base 601 is located on the top of the displacement plate 501, and the rotating motor 602 is located on the first motor base 601 with its output shaft facing upward. The rotating motor 602 is electrically connected to the controller. The angle adjustment mechanism 7 is located at the end of the output shaft of the rotating motor 602. In use, the controller controls the rotating motor 602 to work, which can drive the angle adjustment mechanism 7 to rotate in the horizontal direction of the mounting bracket 2, thereby driving the high-pressure washing gun 9 to rotate, thus achieving a more comprehensive cleaning range.

[0032] The angle adjustment mechanism 7 includes a second motor base 701, an adjusting motor 702, a mounting groove 703, and a connecting block. The second motor base 701 is located at the end of the output shaft of the rotary motor 602. The adjusting motor 702 is horizontally mounted on the second motor base 701. The connecting block is sleeved on the output shaft of the adjusting motor 702. The mounting groove 703 is located on the connecting block and faces inward toward the mounting frame 2. The adjusting motor 702 is electrically connected to the controller. The telescopic mechanism 8 is located on the mounting groove 703. In use, the controller controls the adjusting motor 702 to work, which drives the connecting block to rotate, thereby driving the mounting groove 703 to rotate. This allows the high-pressure washing gun 9 to rotate to adjust its angle, further achieving a more comprehensive cleaning range.

[0033] The telescopic mechanism 8 includes a third motor base 801, a reciprocating motor 802, a second rack 803, and a second gear. The third motor base 801 is fixedly mounted on one side of the mounting groove 703. The reciprocating motor 802 is mounted on the third motor base 801. The second rack 803 is slidably mounted in the mounting groove 703. The high-pressure flushing gun 9 is fixedly connected to the second rack 803. The second gear is sleeved on the output shaft of the reciprocating motor 802 and meshes with the second rack 803. The reciprocating motor 802 is electrically connected to the controller. In use, the controller controls the reciprocating motor 802 to work, which drives the second gear to rotate, thereby causing the second rack 803 to move along the length direction of the mounting groove 703, thus realizing the telescopic movement of the high-pressure flushing gun 9. This improves the flushing force of the high-pressure flushing gun 9 while meeting the cleaning needs of different models of hydraulic supports.

[0034] A telescopic canopy is provided on the base outside the mounting frame 2. The three sides and the top of the mounting frame are covered and sealed by the telescopic canopy. The telescopic canopy is existing technology. The installation of the telescopic canopy helps to prevent the splashing of pollutants such as sewage and coal slag generated during the cleaning process of the hydraulic support.

[0035] The working principle of this invention is as follows: First, the hydraulic support is placed on the electric railcar 3 and controlled by the controller. The electric railcar 3 transports the hydraulic support along the track to the U-shaped mounting bracket 2. Then, the height of the high-pressure flushing gun 9 and the distance between the gun head and the side of the hydraulic support are adjusted according to the different models and sizes of the hydraulic support. When adjusting the height, the controller controls the stepper motor 401 to work, which in turn causes the two rotating screws 402 to rotate, thereby driving the two screw sleeves 403 to rotate, and further driving the lifting rod 404 to move up or down, thereby achieving the purpose of adjusting the height of the high-pressure flushing gun 9. When adjusting the distance between the gun head of the high-pressure flushing gun 9 and the hydraulic support, the controller controls the reciprocating motor 802 to work, which drives the second gear to rotate, thereby causing the second rack 803 to move along the length direction of the mounting groove 703, thereby realizing the extension and retraction of the high-pressure flushing gun 9.

[0036] When cleaning the hydraulic support laterally, the controller simultaneously controls the displacement motor 506, the rotary motor 602, and the water pump. The displacement motor 506 drives the displacement plate 501 to move along the length of the lifting rod 404, that is, along the horizontal direction of the hydraulic support. The rotation of the rotary motor 602 can drive the high-pressure flushing gun 9 to swing left and right along the hydraulic support. At this time, the flushing water can clean the hydraulic support in the horizontal direction through the nozzle of the high-pressure flushing gun 9. At the same time, the start of the stepper motor 401 drives the lifting rod 404 to rise and fall in the height direction of the mounting bracket 2, thereby realizing the lateral cleaning of the entire surface of the hydraulic support.

[0037] During longitudinal cleaning of the hydraulic support, the controller simultaneously controls the displacement motor 506, the adjusting motor 702, and the stepper motor 401. The displacement motor 506 drives the displacement plate 501 to move along the length of the lifting rod 404, that is, along the horizontal direction of the hydraulic support. The rotation of the adjusting motor 702 can drive the high-pressure cleaning gun 9 to swing up and down along the height direction of the hydraulic support, thereby achieving longitudinal cleaning of the hydraulic support. The rotation of the stepper motor 401 can drive the high-pressure cleaning gun 9 to move up and down along the height direction of the hydraulic support, thereby achieving longitudinal cleaning of the entire surface of the hydraulic support, making the cleaning more comprehensive.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
