Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a high-energy, energy-saving, and environmentally friendly lifting hoist device powered by a hydraulic system. Background Technology

[0002] A crane hoist is a widely used lifting device in industry, construction, logistics, and other fields, primarily used for lifting, moving, and hoisting heavy objects. It features a compact structure, simple operation, and high safety and reliability, enabling it to efficiently complete various lifting tasks. A crane hoist typically consists of a steel structure, lifting mechanism, traveling mechanism, swivel mechanism, and control system, achieving the lifting and movement of heavy objects through a mechanical or hydraulic transmission system. In modern industry, crane hoists are gradually developing towards intelligence and automation, equipped with intelligent control systems to achieve functions such as remote monitoring and automatic fault diagnosis. Simultaneously, they emphasize energy conservation and environmental protection, employing energy-saving motors and environmentally friendly materials to reduce energy consumption and environmental pollution.

[0003] However, existing hoists experience significant friction when traveling on the front and rear tracks via the traveling wheels, resulting in unstable operation, high noise levels, and high energy consumption. Long-term use can affect the lifespan of the equipment. Furthermore, after repeated use of lubricating oil, it accumulates on the tracks, which can lead to dust, iron filings, and other impurities entering the guide rails, hindering their normal operation and further accelerating wear. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to reduce the friction between the guide rail and the pulley, extend the service life of the guide rail and the pulley, make the equipment run more smoothly, reduce the noise level, reduce the operation problems caused by friction or jamming, and prevent the accumulation of lubricating oil on the guide rail during use. The recovered lubricating oil can be recycled and reused, further reducing the wear of the guide rail and reducing operating costs.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A high-energy, energy-saving, and environmentally friendly lifting hoist device powered by a hydraulic system includes two crossbeams, which are fixed by a fixing plate. A sliding plate is slidably arranged between the two crossbeams. A lifting component is arranged at the bottom center of the sliding plate. A mounting frame is fixed to one side of each crossbeam, and multiple lubrication components are arranged on the mounting frame.

[0007] The lubrication assembly includes a fixing member fixed on a mounting bracket, a limiting block fixed on the fixing member, a fixing seat provided on the side of the limiting block near the crossbeam, a first telescopic rod provided on the fixing seat, the other end of the first telescopic rod fixed to a sliding block, a first buffer spring sleeved on the first telescopic rod, an arc-shaped contact fixed on the other end of the sliding block, a sliding groove provided on the crossbeam corresponding to the arc-shaped contact, the arc-shaped contact passing through the sliding groove and located on one side of the crossbeam, a squeezing block fixed on one side of the bottom of the sliding block, and an oil outlet sponge provided on the side of the limiting block near the crossbeam.

[0008] As a further embodiment of this utility model, the lifting assembly includes a support column, an electric hoist body is provided at the bottom of the support column, a hydraulic motor is provided on one side of the electric hoist body, a wire rope is wound inside the electric hoist body, a guide reel is provided at the other end of the wire rope, and a hook is provided at the bottom of the guide reel.

[0009] As a further embodiment of this utility model, the extrusion block, the sliding block and the cross frame are all provided with oil outlet holes, and the limiting block is provided with an oil inlet hole corresponding to the oil outlet sponge.

[0010] As a further embodiment of this utility model, a cover plate is provided on each of the lubrication components, and an oil reservoir is provided on one side of each of the lubrication components.

[0011] As a further embodiment of this utility model, guide rails are provided on opposite sides of the two crossbars, positioning plates are provided on the bottom of both sides of the sliding plate, two vertical plates are provided on the bottom of the positioning plates, a motor is provided on one side of the vertical plates, and pulleys are rotatably arranged inside the two vertical plates. The output shaft of the motor is fixed to the pulleys, and the pulleys are located on the guide rails.

[0012] As a further embodiment of this utility model, a guide rod is fixed on one side of the fixing plate, and a slot adapted to the guide rod is provided on the positioning plate.

[0013] As a further embodiment of this utility model, an oil collection box is provided at the bottom of both ends of the guide slide rail, and a leakage groove is provided on the guide slide rail corresponding to the oil collection box.

[0014] As a further embodiment of this utility model, a second telescopic rod is provided on one side of the fixed plate, a second buffer spring is sleeved on the second telescopic rod, and a buffer plate is fixed at the other end of the second telescopic rod. The buffer plate is slidably disposed in the guide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) When this device is needed, start the two motors to drive the pulley to move to the required position in the guide rail. Then start the hydraulic motor to release the wire rope. Through the guide reel, the hook is lowered to the required lifting height. Then hook the goods to be lifted with the hook. Retract the wire rope through the hydraulic motor. The hook moves upward. Then start the motor again. When the pulley moves in the guide rail, the vertical plate will contact the arc-shaped contact. When the vertical plate moves forward, the arc-shaped contact will move into the groove. At this time, the first telescopic rod and the first buffer spring retract inward. The extrusion block extrudes the oil sponge, causing the lubricating oil in the oil sponge to overflow. A small amount of lubricating oil flows out through the oil outlet to the guide rail to lubricate the pulley and guide rail, reduce the friction between the guide rail and the pulley, extend the service life of the guide rail and the pulley, make the equipment run more smoothly, reduce the noise level, and reduce the running problems caused by friction or jamming, thereby improving the operating accuracy and reliability of the equipment.

[0017] (2) When the lubricating oil flows into the guide rail, after the pulley moves, some of the lubricating oil on both sides of the guide rail will flow into the oil collection box through the leakage groove, which avoids the lubricating oil accumulating on the guide rail during use. The recovered lubricating oil can be recycled and reused, which helps to protect the environment and save resources, reduce operating costs, and when the pulley is close to both ends of the guide rail, the buffer plate can reduce the impact of the pulley on the fixed plate and avoid damage to the pulley.

[0028] Please see the appendix Figure 1-6 A high-energy, energy-saving and environmentally friendly lifting hoist device powered by a hydraulic system includes two cross frames 10, which are fixed by a fixing plate 11. A sliding plate 12 is slidably arranged between the two cross frames 10. A lifting component is arranged at the bottom center of the sliding plate 12. A mounting frame 19 is fixed on one side of the cross frame 10, and multiple lubrication components are arranged on the mounting frame 19.

[0029] The lubrication assembly includes a fixing member 20 fixed on the mounting bracket 19. A limiting block 21 is fixed on the fixing member 20. A fixing seat 22 is provided on the side of the limiting block 21 near the cross frame 10. A first telescopic rod 23 is provided on the fixing seat 22. The other end of the first telescopic rod 23 is fixed to a sliding block 25. A first buffer spring 24 is sleeved on the first telescopic rod 23. An arc-shaped contact 26 is fixed on the other end of the sliding block 25. A sliding groove is provided on the cross frame 10 corresponding to the arc-shaped contact 26. The arc-shaped contact 26 passes through the sliding groove and is located on one side of the cross frame 10. A squeezing block 27 is fixed on one side of the bottom of the sliding block 25. An oil outlet sponge 28 is provided on the side of the limiting block 21 near the cross frame 10. Oil outlet holes 29 are provided on the squeezing block 27, the sliding block 25, and the cross frame 10.

[0030] Specifically, during use, when the motor 35 is started, and the pulley 36 moves within the guide rail 32, the vertical plate 34 will contact the arc-shaped contact 26. At this time, as the vertical plate 34 moves forward, the arc-shaped contact 26 will move into the groove. At this time, the first telescopic rod 23 and the first buffer spring 24 retract inward, and the squeezing block 27 squeezes the oil sponge 28, causing the lubricating oil in the oil sponge 28 to overflow. A small amount of lubricating oil flows out through the oil outlet 29 onto the guide rail 32, lubricating the pulley 36 and the guide rail 32, reducing the friction between the guide rail 32 and the pulley 36, extending the service life of the guide rail 32 and the pulley 36, making the equipment run more smoothly, reducing the noise level, and reducing the running difficulties caused by friction or jamming, thereby improving the operating accuracy and reliability of the equipment.

[0031] The lifting assembly includes a support column 13, an electric hoist body 14 is provided at the bottom of the support column 13, a hydraulic motor 15 is provided on one side of the electric hoist body 14, a wire rope 16 is wound inside the electric hoist body 14, a guide reel 17 is provided at the other end of the wire rope 16, and a hook 18 is provided at the bottom of the guide reel 17.

[0032] Specifically, during lifting, the hydraulic motor 15 is started, the wire rope 16 is released, and the hook 18 is lowered to the required lifting height via the guide reel 17. Then, the goods to be lifted are hooked by the hook 18, and the wire rope 16 is retracted by the hydraulic motor 15, causing the hook 18 to move upward. The wire rope 16 is prevented from deviating significantly by the guide reel 17, thus improving the stability of the operation.

[0033] The limiting block 21 has an oil inlet hole 30 at the oil outlet sponge 28, and a cover plate 31 is provided on each of the multiple lubrication components. An oil storage tank 44 is provided on one side of each of the multiple lubrication components.

[0034] When the lubricating oil in the oil sponge 28 is insufficient after repeated squeezing, new lubricating oil is added into the oil storage tank 44. When it is necessary to replenish the lubricating oil in the oil sponge 28, simply open the valve inside the oil storage tank 44, and the lubricating oil inside the oil storage tank 44 will be replenished into the oil sponge 28 through the oil inlet 30.

[0035] Guide rails 32 are provided on opposite sides of the two crossbars 10. Positioning plates 33 are provided on the bottom of both sides of the sliding plate 12. Two vertical plates 34 are provided at the bottom of the positioning plates 33. A motor 35 is provided on one side of the vertical plates 34. A pulley 36 is rotatably arranged inside the two vertical plates 34. The output shaft of the motor 35 is fixed to the pulley 36. The pulley 36 is located on the guide rails 32.

[0036] A guide rod 38 is fixed to one side of the fixing plate 11, and a slot 37 adapted to the guide rod 38 is provided on the positioning plate 33. The guide rod 38 allows the lifting assembly to slide stably within the crossbeam 10, improving the stability of the device.

[0037] The bottom of both ends of the guide slide rail 32 is provided with an oil collection box 39, and a leakage groove 40 is provided on the guide slide rail 32 corresponding to the oil collection box 39.

[0038] A second telescopic rod 41 is provided on one side of the fixed plate 11, a second buffer spring 42 is sleeved on the second telescopic rod 41, and a buffer plate 43 is fixed at the other end of the second telescopic rod 41. The buffer plate 43 is slidably disposed in the guide rail 32.

[0039] When the lubricating oil flows into the guide rail 32, after the pulley 36 moves, some of the lubricating oil located on both sides of the guide rail 32 will flow into the oil collection box 39 through the leakage groove 40, which avoids the lubricating oil accumulating on the guide rail 32 during use. The recovered lubricating oil can be recycled and reused, reducing operating costs. In addition, when the pulley 36 is close to both ends of the guide rail 32, the buffer plate 43 can reduce the impact of the pulley 36 on the fixed plate 11, preventing damage to the pulley 36.

[0040] The working principle of this utility model is as follows:

[0041] When this device is needed, start both motors 35 to drive the pulley 36 to move within the guide rail 32 to the desired position. Then, start the hydraulic motor 15 to release the wire rope 16, which, through the guide reel 17, lowers the hook 18 to the required lifting height. After hooking the load to be lifted with the hook 18, retract the wire rope 16 via the hydraulic motor 15, causing the hook 18 to move upwards. Then, start the motors 35 again. As the pulley 36 moves within the guide rail 32, the vertical plate 34 will contact the arc-shaped contact 26. At this time, as the vertical plate 34 moves forward, the arc... The contact 26 moves into the groove. At this time, the first telescopic rod 23 and the first buffer spring 24 retract inward, and the squeezing block 27 squeezes the oil sponge 28, causing the lubricating oil in the oil sponge 28 to overflow. A small amount of lubricating oil flows out through the oil outlet 29 onto the guide rail 32 to lubricate the pulley 36 and the guide rail 32, reduce the friction between the guide rail 32 and the pulley 36, extend the service life of the guide rail 32 and the pulley 36, make the equipment run more smoothly, reduce the noise level, and reduce the running problems caused by friction or jamming, thereby improving the operating accuracy and reliability of the equipment.

[0042] When the lubricating oil flows into the guide rail 32, after the pulley 36 moves, some of the lubricating oil located on both sides of the guide rail 32 will flow into the oil collection box 39 through the leakage groove 40, which avoids the lubricating oil accumulating on the guide rail 32 during use. The recovered lubricating oil can be recycled and reused, reducing operating costs. In addition, when the pulley 36 is close to both ends of the guide rail 32, the buffer plate 43 can reduce the impact of the pulley 36 on the fixed plate 11, preventing damage to the pulley 36.
