Its working principle involves aspects such as lifting, hoisting, control and safety to ensure that the equipment can work stably and efficiently under various complex conditions.

[0003] The patent with application number CN202410462861.5 discloses a hoisting equipment, including a top beam, a first walking wheel set, a second walking wheel set, a lifting beam, a luffing device, a hook driving device and a hook set; the upper end of the top beam is fixedly connected to a pre-installed large beam in a building; the first walking wheel set is fixedly connected to the top beam; the second walking wheel set is fixedly connected to the top beam, and the first walking wheel set and the second walking wheel set are arranged at intervals; the lifting beam is slidably connected to the first walking wheel set and the second walking wheel set, and the first walking wheel set and the second walking wheel set guide the movement of the lifting beam; the luffing device is in transmission connection with the lifting beam; the hook driving device is fixedly connected to the lifting beam; the hook set is in transmission connection with the hook driving device through a hoisting steel wire rope; the hook driving device and the hook set are respectively located at both ends of the lifting beam. This hoisting equipment can be gradually assembled and carry out hoisting work, solving the problem that it is not easy for a truck crane to enter a high-rise building for large equipment group hoisting. During the use of the above-mentioned special hoisting equipment with adjustment ability, when the machine has not been cleaned for a long time during hoisting goods, dust and impurities will block the inside of the sliding track, making it difficult for the slider to move and difficult to adjust the position of the goods to be hoisted, so a special hoisting equipment with adjustment ability is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a special hoisting equipment with adjustment ability for the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a special lifting device with adjustment ability, including a slide rail, a slider is slidably connected to the top of the slide rail, a first roller is installed on the top of the slide rail, a first motor is fixedly connected to the right side of the slider, a dust scraping device is arranged on the inner wall of the slide rail, a lubricating device is arranged on the inner wall of the slide rail, and a fixing device is arranged at the bottom of the slide rail; the dust scraping device includes a scraper, a second roller, a first cam, a contact plate, a hinged plate, and an extrusion plate. The scraper is fixedly connected to the bottom of the slider, the second roller is slidably connected to the inner wall of the slide rail, the first cam contacts the second roller, the contact plate contacts the first cam, the hinged plate is hinged to the front of the scraper. When the special lifting device is started, the slider moves left and right on the slide rail to drive the scraper to move left and right. The left and right movement of the scraper drives the second roller to rotate in contact with the inner wall of the slide rail. The rotation of the second roller drives the rotation of the first cam. When the first cam rotates, it contacts the contact plate, causing the contact plate to indirectly lift the hinged plate, and push the dust in the chute into the chute opening and fall down for collection. The extrusion plate is fixedly connected to the left side of the slider, the bottom of the extrusion plate is slidably connected to the inner wall of the slide rail, the bottom of the scraper is slidably connected to the inner wall of the slide rail, the circumferential surface of the second roller is in contact with the inner wall of the slide rail, and the left and right sides of the hinged plate are in contact with the inner wall of the slide rail. At the same time, the hinged plate is indirectly lifted to push some broken stones into the chute opening, making it more convenient for the scraper to scrape dust. The fallen dust is extruded by the extrusion plate, so that the dust in the collection box is extruded, reducing the area occupied by the dust in the collection box, enabling the collection box to hold more dust and increasing its usable area. Preferably, the lubricating device includes a second motor, a rotating rod, a first gear, a second gear, a reciprocating lead screw, a connecting column, a fixing plate, a third roller, a connecting rod, a stirring fan, and an oil barrel. The second motor is fixedly connected to the right side of the slide rail through a support plate. The rotating rod is fixedly connected to the output end of the second motor. The first gear is fixedly connected to the circumferential surface of the rotating rod. The second gear meshes with the surface of the first gear. The reciprocating lead screw is fixedly connected to the right side of the second gear. The connecting column is fixedly connected to the circumferential surface of the reciprocating lead screw. The fixing plate is fixedly connected to the circumferential surface of the connecting column. The oil barrel is fixedly installed on the right side of the second gear. The circumferential surface of the third roller is in contact with the inner wall of the oil barrel. The connecting rod is rotatably connected to the inner wall of the fixing plate. The stirring fan is fixedly connected to the circumferential surface of the connecting rod. The second motor drives the rotating rod to rotate. The rotation of the rotating rod drives the first gear to rotate. When the first gear rotates, it drives the second gear to rotate, causing the second gear to drive the oil barrel to rotate. At the same time, the second gear drives the reciprocating lead screw to rotate. The positive and negative spiral grooves on the reciprocating lead screw drive the connecting column to move left and right reciprocally. The left and right reciprocating movement of the connecting column drives the fixing plate to move left and right reciprocally, causing the third roller inside it to slide on the inner wall of the oil barrel. The third roller rotates by friction. The rotation of the third roller drives the connecting rod to rotate. The rotation of the connecting rod drives the stirring fan to rotate, uniformly stirring the lubricating oil inside the oil barrel to prevent it from solidifying inside the oil barrel, resulting in poor lubrication effect. The lubricating device further includes a limiting plate, a second cam, a moving plate, a first spring telescopic column, and a third cam. The limiting plate is fixedly connected to the circumferential surface of the connecting column. The second cam is fixedly connected to the circumferential surface of the reciprocating lead screw. The top of the moving plate is in contact with the circumferential surface of the second cam. The first spring telescopic column is fixedly connected to the inner wall of the oil barrel. The third cam is fixedly connected to the right side of the reciprocating lead screw. The top of the first spring telescopic column is fixedly connected to the bottom of the moving plate. The right side of the second cam is in contact with the inner wall of the oil barrel. The right side of the moving plate is in contact with the inner wall of the oil barrel. The bottom of the limiting plate is slidably connected to the inner wall of the oil barrel. The rotation of the reciprocating lead screw drives the second cam to rotate. When the second cam rotates, it drives the moving plate to move downward. When the moving plate moves downward, through the elastic expansion and contraction of the spring telescopic column, when the moving plate moves up and down reciprocally, the lubricating oil inside the oil barrel is evenly and intermittently dripped onto the workpiece to be lubricated, so that the workpiece will not get stuck during use.

[0006] Preferably, the fixing device includes a second spring telescopic column, a threaded rod, a sleeve, a rope, a connecting block, and a clamping plate. The top of the second spring telescopic column is in contact with the circumferential surface of the third cam. The third cam drives the second spring telescopic column to expand and contract up and down. At the same time, the second spring telescopic column is driven downward by the threaded rod, so that the dripping lubricating oil is smeared more evenly on the device, enhancing its lubricating effect. The threaded rod is rotatably connected to the inner wall of the second spring telescopic column. The sleeve is sleeved on the circumferential surface of the second spring telescopic column. The rope is slidably connected to the inner wall of the threaded rod. The connecting block is fixedly connected to the bottom of the rope. The clamping plate is hinged to the inner wall of the connecting block. At the same time, when the second spring telescopic column moves downward, it presses the sleeve downward. The downward movement of the sleeve drives the connecting block downward. When the connecting block moves downward, it drives the clamping plate to expand, clamping the material to be clamped so that the clamped material is fixed and there is no shaking phenomenon. At the same time, it further prevents the risk of the material falling due to shaking after being lifted, causing unnecessary losses.

[0007] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. For the special lifting equipment with adjustment ability, through the coordinated operation among the scraping plate, the second roller, the first cam, the contact plate, the hinged plate, and the extrusion plate. When the special lifting equipment starts, the scraping plate moves left and right driven by the slider moving left and right on the slide rail. The left and right movement of the scraping plate drives the second roller to contact and rotate on the inner wall of the slide rail. The rotation of the second roller drives the first cam to rotate. When the first cam rotates, it contacts the contact plate, causing the contact plate to indirectly lift the hinged plate, pushing the dust in the chute into the chute opening and falling into the lower part for collection. At the same time, the intermittent lifting of the hinged plate pushes some broken stones into the chute opening, making it more convenient for the scraping plate to scrape the dust. The fallen dust is extruded by the extrusion plate, so that the dust in the collection box occupies less area of the collection box through extrusion, enabling the collection box to hold more dust and increasing its available area.

[0008] 2. The special lifting equipment with adjustment ability operates through the cooperation of the second motor, rotating rod, first gear, second gear, reciprocating lead screw, connecting column, fixed plate, third roller, connecting rod, stirring fan, limiting plate, second cam, moving plate, first spring telescopic column, third cam, and oil barrel. The second motor drives the rotating rod to rotate, the rotating rod drives the first gear to rotate, when the first gear rotates, it drives the second gear to rotate, causing the second gear to drive the oil barrel to rotate. At the same time, the second gear drives the reciprocating lead screw to rotate, and the positive and negative spiral grooves on the reciprocating lead screw drive the connecting column to move left and right reciprocally. The left and right reciprocating movement of the connecting column drives the fixed plate to move left and right reciprocally, enabling the third roller inside it to slide on the inner wall of the oil barrel, causing the third roller to rotate by friction. The rotation of the third roller drives the connecting rod to rotate, and the rotation of the connecting rod drives the stirring fan to rotate, uniformly stirring the lubricating oil inside the oil barrel to prevent it from solidifying inside the oil barrel, resulting in poor lubrication effect. The reciprocating lead screw rotates to drive the second cam to rotate. When the second cam rotates, it drives the moving plate to move downward. When the moving plate moves downward, through the elastic expansion and contraction of the spring telescopic column, when the moving plate moves up and down reciprocally, the lubricating oil inside the oil barrel is evenly and intermittently dripped onto the workpiece that needs to be lubricated, so that the workpiece will not get stuck during use.

[0009] 3. The special lifting equipment with adjustment ability operates through the cooperation of the second spring telescopic column, threaded rod, sleeve, rope, connecting block, and clamping plate. The third cam drives the second spring telescopic column to expand and contract up and down. At the same time, the threaded rod drives the second spring telescopic column to move downward, making the dripped lubricating oil spread more evenly on the device, enhancing its lubrication effect. At the same time, when the second spring telescopic column moves downward, it presses the sleeve to move downward. The downward movement of the sleeve drives the connecting block to move downward. When the connecting block moves downward, it drives the clamping plate to expand, clamping the material to be clamped so that the clamped material is fixed and will not shake. At the same time, it further prevents the risk of the material falling due to shaking after being lifted, causing unnecessary losses. Description of the Drawings
