Technical Field

[0001] This utility model relates to the field of mining machinery and equipment maintenance technology, specifically to a hydraulic device for maintaining mining equipment. Background Technology

[0002] Mines include coal mines, metal mines, non-metal mines, building material mines, and chemical mines, etc. Heavy mining equipment, such as excavators and loaders, is used in mining operations. These mining equipment will be damaged during long-term operation, and the damaged parts need to be repaired after they are damaged.

[0003] When repairing mining equipment, the damaged parts are usually disassembled and placed on a repair platform for maintenance. The repair platform is usually raised and lowered by hydraulic cylinders, which makes it convenient for maintenance personnel to inspect and repair different parts of the damaged equipment. Due to the complex environment in which mining equipment is used, its exterior is often covered with a lot of dust and slag.

[0004] However, when mining equipment is being repaired, the dust and debris carried on its exterior are easily scattered and adhered to the equipment or spread throughout the repair work area. This long-term accumulation of dust and debris not only causes great inconvenience to the repair work, but also poses a serious potential threat to the equipment itself. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments. Example 1

[0029] Reference Figure 1-5 This is the first embodiment of the present utility model, which discloses a hydraulic device for repairing mining equipment, comprising:

[0030] A base 1 is provided, a maintenance plate 3 is provided on top of the base 1, a hydraulic lifting mechanism 2 is provided between the base 1 and the maintenance plate 3, and a protective mechanism 4 is provided on the outside of the maintenance plate 3.

[0031] The hydraulic lifting mechanism 2 includes scissor arms 21 and hydraulic cylinders 22. Two sets of scissor arms 21 are arranged between the maintenance plate 3 and the base 1. The two ends of the hydraulic cylinders 22 are respectively hinged to the two adjacent sets of scissor arms 21.

[0032] The hydraulic lifting mechanism 2 can adjust the height of the maintenance plate 3, thereby raising the mining equipment under maintenance to a suitable height for convenient maintenance.

[0033] The protective mechanism 4 includes mounting cavities 46, with two mounting cavities 46 located on the left and right sides of the maintenance plate 3. Inside each mounting cavity 46 is an upward-opening collection box 41, which collects falling dust and debris, preventing excessive accumulation on the surface of the maintenance plate 3 and its subsequent fall onto the maintenance area floor. The top of the maintenance plate 3 has a through hole 45 communicating with the mounting cavities 46, allowing falling dust and debris to easily enter the collection box 41 below. A pipe 42 is located on the outside of the collection box 41, with a filter box 47 at the other end. A negative pressure fan 48 is located on the outside of the filter box 47, with its air inlet inside the filter box 47. This allows the fan to draw air from the filter box 47, creating a negative pressure environment and generating suction. A cleaning component 43 is located at the bottom of the filter box 47.

[0034] Specifically, a pad 44 is fixedly connected to the top of the maintenance plate 3. The pad 44 can support the bottom of the mining equipment being maintained, so that its bottom is away from the top of the maintenance plate 3. This facilitates maintenance and also allows dust and debris to enter the through holes 45. The through holes 45 are densely distributed at equal intervals on the top of the maintenance plate 3. A detachable connector 421 is provided at one end of the pipe 42 near the collection box 41. The other end of the detachable connector 421 is connected to the inside of the collection box 41. A valve 422 is provided in the middle of the pipe 42. Under the action of the detachable connector 421, the pipe 42 can be connected to the inside of the collection box 41, and the air in the collection box 41 can be drawn out, so that the air carries dust and debris into the filter box 47 for filtration.

[0035] Valve 422 can close pipe 42 when cleaning filter screen 471 to prevent cleaning dust from flowing back into the environment. Filter screen 471 is fixedly connected to the inside of filter box 47. Filter screen 471 filters incoming dust and debris and blocks dust and debris. A fine grille 49 is provided on the side of collection box 41 near pipe 42. The fine grille 49 can block clumps of dust and debris in collection box 41, making it convenient to clean directly through collection box 41. Example 2

[0036] Reference Figure 1-5This is the second embodiment of the present invention, which differs from the first embodiment in that: the cleaning component 43 includes a dust box 431, which is disposed below the filter box 47. The dust box 431 can collect dust and debris entering through the connecting pipe 432. The dust box 431 is periodically removed to clean the dust and debris inside. A connecting groove 434 is provided at the bottom of the filter box 47, and a connecting pipe 432 communicating with the connecting groove 434 is provided at the bottom of the filter box 47. A drive motor 437 is fixedly connected to the outside of the filter box 47, and a transmission rod is fixedly connected to the drive motor 437 through an output shaft. 436, a fan blade 433 is fixedly connected to the outside of the transmission rod 436, and a brush strip 435 is fixedly connected to the outside of the transmission rod 436. The brush strip 435 cleans the dust and debris adsorbed on the filter screen 471 and causes it to enter the connecting groove 434 below. When cleaning the filter screen 471, the drive motor 437 drives the brush strip 435 to rotate through the output shaft and the transmission rod 436. The rotation of the brush strip 435 cleans the filter screen 471. The fan blade 433 can drive the air to flow towards the filter screen 471, preventing the brush strip 435 from pushing fine dust to the right side of the filter screen 471 and protecting the negative pressure fan 48.

[0037] The remaining structure is the same as that in Example 1.

[0038] The workflow of this utility model is as follows:

[0039] The mining equipment that needs to be repaired is hoisted to the top of the repair plate 3 by the hoisting equipment and placed on the top of the pad 44. The hydraulic lifting mechanism 2 can be used to adjust it to an appropriate height. When the mining equipment is being repaired, dust and debris on the mining equipment fall off, and some of the dust and debris enters the collection box 41 below directly through the through hole 45.

[0040] When the negative pressure fan 48 starts, it draws the gas in the filter box 47 outward. Under the action of the pipe 42 and the mounting cavity 46, the through hole 45 generates suction, which sucks up the dust on the top of the maintenance plate 3 and the dust that falls on it. The air carries the dust and debris into the filter box 47 through the pipe 42. Under the action of the filter screen 471, the dust and debris in the air are filtered and blocked to the left side of the filter screen 471. Under the action of gravity, some of the dust and debris enters the dust box 431 below through the connecting groove 434 and the connecting pipe 432 for collection.

[0041] When cleaning the filter screen 471, close the valve 422. The drive motor 437 drives the transmission rod 436 to rotate through the output shaft. The rotation of the transmission rod 436 drives the brush strip 435 to rotate. The rotation of the brush strip 435 cleans the filter screen 471. The fan blade 433 on the outside of the transmission rod 436 rotates, which can drive the air to flow to one side of the filter screen 471. Together with the brush strip 435, the dust is cleaned from the filter screen 471 and enters the connecting groove 434. The dust box 431 is removed periodically for cleaning.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
