[0002] Specialized electromechanical equipment refers to eight categories of equipment involving life safety and high risk, including boilers, pressure vessels (including gas cylinders), pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities, and special-purpose motor vehicles for use within plants and factories. During the installation of specialized electromechanical equipment, many small components need to be installed. In actual operation, due to the relatively high main structure of such equipment, lifting devices are required to transport these components to the top for installation, thereby improving the efficiency of the installation work.

[0003] According to Chinese Patent Publication No. CN 221795890 U, a special electromechanical equipment installation and lifting device is disclosed, including a mobile frame and an operating platform. The operating platform has through holes, and a bucket elevator is inserted through the holes. The bucket elevator can continuously transport small parts to the operating platform, and then the workers on the operating platform can transfer them to the workers on the main body of the special electromechanical equipment. This can ensure safety and speed up the lifting of parts.

[0004] However, the height of the operating table in the aforementioned patent is fixed and cannot be adjusted according to actual use. It is also inconvenient to store and tidy up. In addition, the aforementioned patent moves and is supported by the bottom casters. Due to the small contact area of ​​the casters, the whole device cannot be fixed on uneven ground. The casters deflect and cause the device to slip and tilt, affecting the safety of the operator on the operating table. Utility Model Content

[0005] The purpose of this utility model is to provide a special electromechanical equipment installation and lifting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special electromechanical equipment installation and lifting device, comprising a base plate, an operating platform above the base plate, a conveyor belt fixedly installed on the operating platform, the upper surface of the base plate being rotatably connected to the bottom of a sleeve, a threaded rod inside the sleeve, a worm gear fixedly connected to the outer side of the sleeve, the upper surface of the base plate being fixedly connected to the threaded cylinder, an adjusting rod inside the threaded cylinder, the bottom end of the adjusting rod being rotatably connected to a moving plate, and several support columns being provided on the moving plate.

[0007] Preferably, the upper surface of the base plate is fixedly connected to the slide rail, the side of the conveyor belt is rotatably engaged with the connecting slider, the side of the connecting slider has a sliding groove, and the connecting slider slides with the outer side of the slide rail through the sliding groove.

[0008] Preferably, the upper surface of the base plate is fixedly connected to the housing, a motor is fixedly installed on the side of the housing, the output end of the motor is fixedly connected to the worm gear, the outer side of the worm gear is meshed with the worm wheel, and the housing is rotatably connected to the outer side of the sleeve through a sealed bearing.

[0009] Preferably, the sleeve has a threaded groove inside, and the sleeve is threaded to the outer side of the threaded rod through the threaded groove. The sleeve and the threaded rod are symmetrically distributed at the bottom of the operating table, and the top end of the threaded rod is fixedly connected to the operating table.

[0010] Preferably, the bottom surface of the operating table is fixedly connected to the top end of the limiting rod, the bottom end of the limiting rod is fixedly connected to the base plate, and the limiting rod has a telescopic function.

[0011] Preferably, the threaded cylinder has a threaded groove inside, the outer side of the adjusting rod is threaded to the inner thread of the threaded cylinder, and the bottom end of the threaded cylinder extends to the bottom plate and rotates with the moving plate.

[0012] Preferably, the upper surface of the movable plate is fixedly connected to several cylindrical bodies, the inside of the cylindrical bodies is slidably fitted with a support column, and a spring is sleeved inside the cylindrical bodies.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a motor to drive the worm gear and sleeve to rotate, thereby causing the threaded rod to move inside the sleeve. With the cooperation of the telescopic limit rod, the operating platform can be raised and lowered. While the operating platform is raised and lowered, the connecting slider at the bottom of the conveyor belt moves outside the slide rail, ensuring that the parts can still be transported to the top of the operating platform by the conveyor belt even when the height of the operating platform changes. This effectively enhances the actual use effect of the overall lifting device and reduces the area occupied by the storage.

[0015] 2. This utility model also pushes the moving plate downward by rotating the adjusting rod, and expands the contact area between the whole device and the ground by the support column and the moving plate. At the same time, the elastic force of the spring ensures that the support column is in contact with the ground, so that the whole device can still be effectively fixed on uneven ground and avoid the situation of slippage caused by the moving wheel shifting.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a special electromechanical equipment installation and lifting device, comprising: a base plate 1, four symmetrical self-locking casters on the bottom surface of the base plate 1; an operating platform 2 above the base plate 1, the operating platform 2 being fixedly connected to a mounting plate; the side of the mounting plate being connected to the side of a conveyor belt 3 via a rotating shaft; a drive source and transmission belt on the side of the conveyor belt 3 enabling movement and conveying; several baffles fixedly connected to the outer side of the conveyor belt 3 to prevent bottom parts from falling during conveying; an entrance hole in the ground of the operating platform 2; and a ladder fixedly connected to the bottom surface of the operating platform 2.

[0023] The upper surface of the base plate 1 is fixedly connected to the slide rail 5. The side of the conveyor belt 3 is rotatably engaged with the connecting slider 4. The connecting slider 4 has a sliding groove on its side, and it slides against the outer side of the slide rail 5 through the groove. When the height of the operating platform 2 changes, the position of the top of the conveyor belt 3 remains unchanged, while the connecting slider 4 at the bottom of the conveyor belt 3 slides on the surface of the slide rail 5. The tilt angle of the conveyor belt 3 is adjusted to match the change in the height of the operating platform 2, enhancing the practicality of operation.

[0024] The upper surface of the base plate 1 is rotatably connected to the bottom of the sleeve 6. The sleeve 6 has a threaded groove inside, which engages with the outer thread of the threaded rod 7. The sleeve 6 and threaded rod 7 are symmetrically distributed at the bottom of the operating table 2. The top of the threaded rod 7 is fixedly connected to the operating table 2, and the outer side of the sleeve 6 is fixedly connected to the worm gear 11. The upper surface of the base plate 1 is fixedly connected to the housing 8. The side of the housing 8 is fixedly connected to the motor 9 via bolts. The output end of the motor 9 is fixedly connected to the worm 10. The outer side of the worm 10 meshes with the worm gear 11. Lubricating oil is applied to both the worm 10 and the worm gear 11. The purpose of the housing 8 is to reduce the impact of dust and impurities on the worm 10 and worm gear 11, ensuring the transmission effect of the worm 10 and worm gear 11. The worm 10 and worm gear 11 still require regular inspection and maintenance by maintenance personnel. The housing 8 is rotatably connected to the outer side of the sleeve 6 via a sealed bearing.

[0025] The bottom surface of the operating platform 2 is fixedly connected to the top end of the limiting rod 12, and the bottom end of the limiting rod 12 is fixedly connected to the base plate 1. The limiting rod 12 has a telescopic function.

[0026] The upper surface of the base plate 1 is fixedly connected to the threaded cylinder 13. The threaded cylinder 13 has a threaded groove inside. The outer side of the adjusting rod 14 engages with the internal thread of the threaded cylinder 13 via threads. The bottom end of the threaded cylinder 13 extends below the base plate 1 and rotatably engages with the movable plate 15. The upper surface of the movable plate 15 is fixedly connected to several cylinders 16. The interior of each cylinder 16 is slidably engaged with a support column 17. A spring 18 is fitted inside each cylinder 16. The spring force of the spring 18 ensures that the bottom end of the support column 17 is in contact with the ground. The support column 17 expands the contact area of ​​the entire device, improving stability and allowing for placement and fixation on uneven ground, ensuring the safety of the entire device.

[0027] Working Principle: During use, the entire unit is easily moved via the casters at the bottom of the base plate 1. Then, by rotating the adjusting rod 14, it moves within the threaded cylinder 13, causing the moving plate 15 to move downwards until the support column 17 is in contact with the ground. Springs 18 ensure that the support column 17 at different positions is in contact with the ground, increasing the contact area and maintaining good stability even on uneven surfaces, ensuring the safety of the workers on the operating platform 2. Workers on the ground place parts on the surface of the conveyor belt 3, which transports the parts to the top of the operating platform 2. Workers on the operating platform 2 then transfer and distribute the parts to the personnel installing the special electromechanical equipment.

[0028] When the height of the operating platform 2 needs to be adjusted, the motor 9 causes the worm gear 10 to drive the worm wheel 11 and the sleeve 6 to rotate synchronously, thereby causing the threaded rod 7 to move up and down inside the sleeve 6, thus realizing the height adjustment of the operating platform 2. At the same time, the change in the height of the operating platform 2 will synchronously drive the conveyor belt 3 to move, thereby causing the connecting slider 4 to slide on the slide rail 5, avoiding the interference of the conveyor belt 3 on the height adjustment of the operating platform 2.
