[0002] The clamping device for repairing parts of open-pit coal mining machinery is a special tooling adapted for the repair of heavy engineering machinery such as open-pit coal mining excavators, mining trucks, loaders, and breakers. Its core purpose is to accurately position and firmly clamp engineering machinery parts of different specifications and shapes, such as pins, gears, hubs, housings, clamping bolts, and giant tires.

[0003] Patent application CN209533191U discloses a clamping device for repairing parts of coal mine open-pit engineering machinery equipment, including a base. Support columns are fixedly connected to the left and right sides of the top of the base. Two sliding rods are fixedly connected inside the support columns. A sleeve is fixedly connected to the bottom of the inner wall of the support column. A threaded rod is sleeved on the end of the sleeve away from the bottom of the inner wall of the support column. A bearing is embedded in the top of the support column. The inner ring of the bearing is fixedly sleeved with the surface of the threaded rod.

[0004] However, this patent also has the following shortcomings: welding and hammering operations during maintenance generate severe vibrations, and the existing anti-loosening structure design is insufficient, making it easy for the clamps to loosen. Furthermore, dust and coal sludge from open-pit mines easily adhere to the clamping contact surface, clogging the anti-slip grooves and wearing down the anti-slip pads, significantly reducing clamping friction. Heavy parts are prone to slippage, affecting maintenance accuracy and posing a safety hazard of parts falling off. To address this issue, a clamping device for the maintenance of parts in open-pit coal mine engineering machinery is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping device for the maintenance of parts of open-pit coal mine engineering machinery, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a clamping device for repairing parts of coal mine open-pit engineering machinery equipment, including a working cart, a control box fixedly connected to the top of the working cart, a telescopic rod slidably connected to the top of the control box, a swing arm fixedly connected to the surface of the telescopic rod, a placement plate fixedly connected to the end of the swing arm away from the telescopic rod, and a blowing mechanism provided on the inner wall of the placement plate.

[0008] According to the above technical solution, the scraper blade is made of compressible rubber material, the cleaning ring has compressible elasticity, the surface of the spraying disc is provided with spraying holes, and the cleaning ring uses its own compressible elasticity to drive the rubber scraper blade to tightly fit the clamping surface of the device.

A mounting frame is fixedly connected to the bottom of the mounting plate, and a sliding ring is fixedly connected to the bottom of the mounting frame. A placement pad is slidably connected to the inner wall of the sliding ring, and clamping rings are fixedly connected to both ends of the placement pad. A clamping assembly is provided on the inner wall of the mounting plate. The placement pad is driven to slide radially by the internal telescopic device of the mounting frame in cooperation with the sliding ring.

[0010] According to the above technical solution, the clamping assembly includes a rotating arm. One end of the rotating arm is rotatably connected to the inner wall of the mounting plate via a rotating shaft. An adjusting cylinder is rotatably connected to the end of the rotating arm away from the mounting plate.

A compression membrane is fixedly connected to the top of the adjusting rod. An adsorption plate is fixedly connected to the surface of the compression membrane. A contact ring is fixedly connected to the surface of the compression membrane. The end of the contact ring away from the compression membrane is slidably connected to the inner wall of the telescopic box. The inner wall of the placement plate is provided with a covering mechanism. After the part is positioned, the driver on the inner wall of the mounting plate is activated, causing the rotating arm to rotate circumferentially around the rotating shaft.

[0011] According to the above technical solution, the placement pad has a compressible reset function, the two ends of the clamping ring are set as semi-circular rings, the surface of the clamping ring is provided with adsorption holes, and the clamping ring is made of rubber material with compressible elasticity. The semi-circular clamping ring of rubber material will first elastically fit the outer surface of the part.

[0012] According to the above technical solution, the adsorption plate is made of permanent magnet material, the inner wall of the compression film is equipped with a friction ring, the surface of the contact ring is provided with a contact ring, the contact ring has a compression elastic function, and the inner and outer sides are extended by the adjusting cylinder, so that the telescopic box moves to further fine-tune the clamping position, and the adjusting rod drives the compression film to accurately fit the surface of the part.

[0013] According to the above technical solution, the covering mechanism includes a connecting plate, which is fixedly connected to the inner wall of the placement tray. A telescopic cylinder is fixedly connected to the surface of the connecting plate, and a push rod is slidably connected to the bottom of the telescopic cylinder. A covering ring is fixedly connected to the bottom of the push rod, and a covering film is fixedly connected to the right side of the covering ring. A friction pad is fixedly connected to the inner wall of the covering film, and a buffer assembly is provided on the inner wall of the covering ring. When the telescopic cylinder switch is activated, the push rod drives the covering ring to move downward.

[0014] According to the above technical solution, the buffer assembly includes a buffer cylinder, which is fixedly connected to the inner wall of the covering ring. A compression column is slidably connected to the inner wall of the buffer cylinder, and a telescopic ring is fixedly connected to the surface of the compression column. A buffer membrane is fixedly connected to the end of the telescopic ring away from the compression column, and the buffer membrane is slidably connected to the inner wall of the buffer cylinder. A mounting pad is fixedly connected to the end of the compression column away from the buffer cylinder, and a pressure frame is fixedly connected to the inner wall of the mounting pad. The compression column slides inside the buffer cylinder using its own compression-resistant elastic properties, while the telescopic ring expands and contracts synchronously. The buffer membrane absorbs the impact force brought by vibration.

[0015] According to the above technical solution, the surface of the pressure frame is provided with a partition groove, the pressure frame has the characteristic of being able to extend and retract inward and outward, the compression column is made of a compression-resistant elastic material, the buffer membrane is made of a membrane material that can absorb vibration, and the pressure frame utilizes its own characteristic of being able to extend and retract inward and outward to always elastically press the surface of the part, preventing the clamping surface from loosening due to vibration.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a placement mechanism, utilizes the compressible and repositionable characteristics of the placement pad to buffer the impact of gravity when placing the part. At the same time, the adsorption holes on the surface of the clamping ring will generate initial negative pressure adsorption on the surface of the part, completing the positioning and support clamping of the part, laying the foundation for subsequent precise clamping. By setting up this mechanism, the cooperation between the placement pad and the sliding ring can adapt to engineering machinery parts of different specifications and sizes, improving the clamping adaptability of the device and eliminating the need for frequent tooling changes.

[0017] 2. This invention, by setting up a covering mechanism, uses a buffer membrane to absorb the impact force brought by vibration, gradually dissipating the vibration potential energy. At the same time, the pressure frame utilizes its own inward and outward stretching characteristics to always elastically press the surface of the part, preventing the clamping surface from loosening due to vibration. By setting up this mechanism, the full-circumference covering structure can effectively prevent dust and coal sludge in the open-air working environment from re-entering the clamping surface, continuously ensuring the friction of the clamping surface, and achieving full-process anti-fouling protection during the clamping process.

[0018] 3. This invention cleans dust and coal sludge from the clamping surface by setting up a blowing mechanism, avoiding impurities from clogging the anti-slip texture and wearing down the anti-slip components, ensuring the friction coefficient of the clamping surface. At the same time, the rotating air jet can achieve thorough cleaning of the clamping surface without dead angles, and the elastic scraper can scrape off the sticky coal sludge. Compared with the traditional single air blowing cleaning, the cleaning is more thorough and suitable for the harsh working conditions of open-pit coal mines with a lot of dust and coal sludge.

[0019] 4. This invention, by setting up a clamping assembly, utilizes an adsorption disk made of permanent magnet material to generate strong magnetic attraction to engineering machinery parts. Simultaneously, the friction ring on the inner wall of the compression film increases the contact friction with the surface of the part. The contact ring slides elastically on the inner wall of the telescopic box, ensuring that the compression film is always tightly attached to the surface of the part, achieving a strong clamping at multiple points and with a strong fit. By setting up this mechanism, the elastic compression characteristics of the compression film and the contact ring can adapt to the surface structure of irregularly shaped parts, solving the problem of poor fit between traditional fixed clamping structures and irregularly shaped parts, ensuring the sealing of the clamping surface, and preventing dust and coal slurry from entering the clamping surface.

[0022] 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.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Example 1: See Figures 1-4The present invention provides a technical solution: a clamping device for repairing parts of coal mine open-pit engineering machinery equipment, including a working vehicle 1, a control box 2 fixedly connected to the top of the working vehicle 1, a telescopic rod 3 slidably connected to the top of the control box 2, a swing arm 4 fixedly connected to the surface of the telescopic rod 3, a placement plate 5 fixedly connected to the end of the swing arm 4 away from the telescopic rod 3, and a blowing mechanism 8 provided on the inner wall of the placement plate 5. The placement mechanism 6 includes a mounting plate 601, which is fixedly connected to the inner wall of the placement plate 5. A mounting frame 602 is fixedly connected to the bottom of the mounting plate 601, and a sliding ring 606 is fixedly connected to the bottom of the mounting frame 602. A placement pad 603 is slidably connected to the inner wall of the sliding ring 606, and clamping rings 604 are fixedly connected to both ends of the placement pad 603. A clamping assembly 605 is provided on the inner wall of the mounting plate 601. When the control switch of the work cart 1 is turned on, the work cart 1 is first flexibly moved to the maintenance work point. The telescopic rod 3 is extended and retracted by the control box 2, and then rotated by the swing arm 4 to adjust the height of the placement plate 5 so as to align it horizontally with the work position, thereby adapting to the maintenance needs of uneven open-air sites. The internal telescopic device of the mounting frame 602, in conjunction with the sliding ring 606, drives the placement pad 603 to slide radially. The support range can be adaptively adjusted according to the size of the maintenance parts. At this time, the semi-circular clamping ring 604 made of rubber will first elastically fit against the outer surface of the parts.

[0026] The clamping assembly 605 includes a rotating arm 6051. One end of the rotating arm 6051 is rotatably connected to the inner wall of the mounting plate 601 via a rotating shaft. An adjusting cylinder 6052 is rotatably connected to the end of the rotating arm 6051 away from the mounting plate 601. A telescopic box 6053 is fixedly connected to the end of the adjusting cylinder 6052 away from the rotating arm 6051. An adjusting rod 6054 is slidably connected to the top of the telescopic box 6053. A compression membrane 6055 is fixedly connected to the top of the adjusting rod 6054. An adsorption plate 6056 is fixedly connected to the surface of the compression membrane 6055. A contact ring 60 is fixedly connected to the surface of the compression membrane 6055. 57. The end of the contact ring 6057 away from the compression membrane 6055 is slidably connected to the inner wall of the telescopic box 6053. The inner wall of the placement tray 5 is provided with a covering mechanism 7. The placement pad 603 uses its compressible and resetting characteristics to buffer the impact of gravity when the part is placed. At the same time, the adsorption holes on the surface of the clamping ring 604 will generate a preliminary negative pressure adsorption on the surface of the part, completing the positioning and support clamping of the part, laying the foundation for subsequent precise clamping. Through the cooperation of the placement pad 603 and the sliding ring 606, it can adapt to engineering machinery parts of different specifications and sizes, improve the clamping adaptability of the device, and eliminate the need for frequent tooling changes.

[0027] Traditional devices have a fixed support range and poor adaptability to engineering machinery parts of different specifications and sizes, requiring frequent tooling changes, which reduces maintenance efficiency. At the same time, the impact of gravity when placing heavy parts can easily cause the device to shake and the parts to shift. Traditional devices have no buffer structure, which will create a risk of loosening in subsequent clamping. Therefore, it is necessary to set up a clamping component 605.

[0028] The placement pad 603 has a compressible reset function. The two ends of the clamping ring 604 are set as semi-circular rings. The surface of the clamping ring 604 is provided with adsorption holes. The clamping ring 604 is made of rubber material with compressibility elasticity. After the part is positioned, the driver on the inner wall of the mounting plate 601 is activated, which drives the rotating arm 6051 to rotate around the rotating shaft. The clamping points of multiple sets of rotating arms 6051 are adjusted according to the shape of the part and the clamping requirements. The inner and outer extension and retraction of the adjusting cylinder 6052 causes the telescopic box 6053 to move and further fine-tune the clamping position. The adjusting rod 6054 drives the compression film 6055 to accurately fit the surface of the part. The adsorption plate 6056 made of permanent magnet material will generate a strong magnetic attraction to the engineering machinery parts.

[0029] The adsorption plate 6056 is made of permanent magnet material. A friction ring is installed on the inner wall of the compression membrane 6055. A contact ring 6057 is formed on the surface of the contact ring 6057. The contact ring 6057 has a compressive elastic function. The friction ring on the inner wall of the compression membrane 6055 increases the contact friction with the surface of the part. The contact ring 6057 slides elastically on the inner wall of the telescopic box 6053, ensuring that the compression membrane 6055 is always tightly attached to the surface of the part, realizing a strong clamping with multiple points and strong fit. Through the elastic compression characteristics of the compression membrane 6055 and the contact ring 6057, it can adapt to the surface structure of irregular parts, solve the problem of poor fit between traditional fixed clamping structures and irregular parts, ensure the sealing of the clamping surface, and prevent dust and coal sludge from entering the clamping surface.

[0030] Example 2: Based on Example 1, please refer to the following... Figures 5-6The present invention provides a technical solution: the covering mechanism 7 includes a connecting plate 701, which is fixedly connected to the inner wall of the placement tray 5. A telescopic cylinder 702 is fixedly connected to the surface of the connecting plate 701. A push rod 703 is slidably connected to the bottom of the telescopic cylinder 702. A covering ring 704 is fixedly connected to the bottom of the push rod 703. A covering film 705 is fixedly connected to the right side of the covering ring 704. A friction pad 706 is fixedly connected to the inner wall of the covering film 705. A buffer assembly 707 is provided on the inner wall of the covering ring 704. After the part is accurately clamped, the telescopic cylinder 702 is activated, causing the push rod 703 to drive the covering ring 704 to move downward. When the covering ring 704 drives the covering film 705 to move to the surface of the part, the covering film 705 will tightly adhere to the outer surface of the part, forming a full circumference covering of the part. The friction pad 706 on the inner wall of the covering film 705 further increases the contact friction with the surface of the part, realizing secondary fixation of the clamping.

[0031] The buffer assembly 707 includes a buffer cylinder 7071, which is fixedly connected to the inner wall of the covering ring 704. A compression column 7074 is slidably connected to the inner wall of the buffer cylinder 7071. A telescopic ring 7073 is fixedly connected to the surface of the compression column 7074. A buffer membrane 7072 is fixedly connected to the end of the telescopic ring 7073 away from the compression column 7074. The buffer membrane 7072 is slidably connected to the inner wall of the buffer cylinder 7071. A mounting pad 7075 is fixedly connected to the end of the compression column 7074 away from the buffer cylinder 7071. A pressure frame 7076 is fixedly connected to the inner wall of the mounting pad 7075. At the same time, the violent vibrations generated by welding and hammering during maintenance will be transmitted to the covering ring 704. At this time, the compression column 7074 slides in the buffer cylinder 7071 using its own compression-resistant elastic properties, while the telescopic ring 7073 will expand and contract synchronously. The impact force brought by the vibration is absorbed by the buffer membrane 7072, and the vibration potential energy is gradually dissipated.

[0032] Traditional clamping devices lack an active vibration buffer structure. The intense vibrations generated by welding and hammering are directly transmitted to the clamping surface, causing the clamping components to loosen. Furthermore, traditional devices only provide localized clamping without a secondary reinforcement structure. Under vibration, the clamping surface is prone to relative displacement with the surface of the part. Therefore, a buffer component 707 is required.

[0033] The pressure frame 7076 has partition grooves on its surface and can extend and retract inwards and outwards. The compression column 7074 is made of compression-resistant elastic material, and the buffer membrane 7072 is made of a membrane material that can absorb vibration. At the same time, the pressure frame 7076 uses its ability to extend and retract inwards and outwards to always elastically press the surface of the part, preventing the clamping surface from loosening due to vibration. The full-circumference covering structure can effectively prevent dust and coal sludge in the open-air working environment from re-entering the clamping surface, continuously ensuring the friction of the clamping surface, and achieving full-process anti-fouling protection during the clamping process.

[0034] Example 3: Based on Example 2, please refer to the following... Figures 7-8 The present invention provides a technical solution: the blowing mechanism 8 includes a storage box 801, which is fixedly connected to the inner wall of the placement tray 5. A compression tank 802 is fixedly connected to the top of the storage box 801, and a transmission pipe 803 is fixedly connected to the inner wall of the compression tank 802. A rotating rod 804 is rotatably connected to the top of the storage box 801, and a jet plate 805 is fixedly connected to the top of the rotating rod 804. The end of the transmission pipe 803 away from the compression tank 802 is fixedly connected to the surface of the jet plate 805. Before clamping operations or during maintenance, the pneumatic valve inside the compression tank 802 is activated to generate high-pressure gas. The high-pressure gas is transported to the jet plate 805 through the transmission pipe 803. Then, through the controller inside the storage box 801, the rotating rod 804 drives the jet plate 805 to rotate to a certain extent, thereby performing high-pressure jetting on the inside of the placement tray 5 and the clamping surface of the parts to remove dust and fine coal slime particles attached to the surface of the parts.

[0035] The cleaning assembly 806 includes a placement frame 8061, which is fixedly connected to the left side of the storage box 801. The top of the placement frame 8061 is fixedly connected to an installation cavity 8062. An ejection plate 8063 is fixedly connected to the inner wall of the installation cavity 8062. A cleaning ring 8064 is fixedly connected to the left side of the inner wall of the installation cavity 8062. A scraper 8065 is fixedly connected to the end of the cleaning ring 8064 away from the inner wall of the installation cavity 8062. A placement mechanism 6 is provided on the inner wall of the placement plate 5. At the same time, the high-pressure gas inside the compression tank 802 enters the ejection plate 8063 through the placement frame 8061, so that the ejection plate 8063 synchronously ejects high-pressure gas onto the surface of the clamping device. The cleaning ring 8064 uses its own compression elasticity to drive the rubber scraper 8065 to tightly adhere to the clamping surface of the device and scrapes with the gas blowing, thereby removing the sticky coal slime attached to the surface of the clamping device.

[0036] Traditional clamping devices lack a dedicated clamping surface cleaning structure and rely solely on manual cleaning, which is not only inefficient and incomplete but also increases the labor intensity of operators. Furthermore, open-pit coal mines have high dust and coal sludge content, and the sticky coal sludge easily adheres to the clamping surface and the surface of the parts, clogging the anti-slip texture and wearing down the anti-slip components, fundamentally reducing the friction coefficient of the clamping surface. Therefore, it is necessary to set up a cleaning component 806.

[0037] The scraper blade 8065 is made of compressible rubber material, the cleaning ring 8064 has compressible elasticity, and the surface of the spray plate 8063 is provided with spray holes. The cleaning operation can be carried out simultaneously with the clamping operation to prevent dust and coal sludge from re-adhering during maintenance. It cleans the dust and coal sludge on the clamping surface from the source, avoids impurities clogging the anti-slip texture and wearing the anti-slip parts, and ensures the friction coefficient of the clamping surface. At the same time, the rotating air jet can achieve a thorough cleaning of the clamping surface without dead angles, and the elastic scraper blade 8065 can scrape off sticky coal sludge. Compared with the traditional single air blowing cleaning, the cleaning is more thorough and suitable for the harsh working conditions of open coal mines with a lot of dust and coal sludge.
