Description

Technical Field

[0001] This application relates to a simple lifting machine, belonging to the technical field of parts production and processing equipment. Background Technology

[0002] In the manufacturing and processing industry, optimizing the material conveying process from the ground to the roller conveyor is crucial for improving overall production efficiency. As the core equipment for horizontal material transportation on the production line, the roller conveyor is widely used in various production scenarios due to its efficient and continuous conveying capabilities, and can stably deliver materials to various processing stations.

[0003] Traditional lifting methods rely heavily on manual handling or complex lifting equipment. Manual handling is not only labor-intensive and inefficient, but also poses significant safety hazards when moving heavy or large items. Complex lifting equipment is typically bulky and expensive; for small-scale operations or situations where lifting precision requirements are not extremely high, using complex equipment leads to resource waste, and its installation and operation are relatively complex, requiring professional personnel for operation and maintenance. Therefore, developing a simple lifting machine that is structurally simple, low-cost, easy to operate, and can meet certain lifting needs is of significant practical importance.

[0009] Preferably, stiffening plates are welded between the two vertical channel steel structures and the base frame structure. The stiffening plates are located at the connecting corners and are used to disperse stress concentration when the vertical channel steel structures are subjected to force.

[0010] Preferably, the tops of the two vertical channel steel structures are connected by a second crossbeam structure to form a closed frame, thereby enhancing the overall torsional stiffness.

[0011] Preferably, linear slide rails are fixedly connected to both of the vertical channel steel structures.

[0026] like Figures 1-5 As shown, a simple hoist includes: a base frame structure 1, two vertical channel steel structures 2, a loading platform 15, and a hoisting device.

[0027] Specifically, the base frame structure 1 is a rigid welded structure, serving as the supporting foundation for the entire hoist. Two vertical channel steel structures 2 are symmetrically fixedly connected to the base frame structure 1, and a first crossbeam structure 3 is fixedly connected between the two vertical channel steel structures 2. The tops of the two vertical channel steel structures 2 are connected by a second crossbeam structure 4, forming a closed frame. This closed frame structure enhances the overall torsional rigidity of the hoist, effectively resisting torsional forces during hoisting, ensuring normal operation of the equipment, and extending its service life. Stiffening plates 5 are fixedly connected between the two vertical channel steel structures 2 and the base frame structure 1. The stiffening plates 5 are fixed by bolts or welding and are located at the connecting corners to disperse stress concentration when the vertical channel steel structures 2 are subjected to force, enhancing the connection strength between the vertical channel steel structures 2 and the base frame structure 1, and improving the structural stability of the entire equipment. Support feet 17 with adjusting bolts are installed at the four corners of the base frame structure 1 to adjust the height and level of the equipment, ensuring stable placement even on uneven ground.

[0028] The loading platform 15 is slidably connected to two vertical channel steel structures 2. Specifically, each of the two vertical channel steel structures 2 is fixedly connected to a linear slide rail 13, which is fixed along the length of the vertical channel steel structure 2. A linear slide block 14 matching the linear slide rail 13 is fixedly connected to the loading platform 15, and the linear slide block 14 is slidably connected to the linear slide rail 13. Further, multiple unpowered free rollers 16 are installed at equal intervals along the length of the loading platform 15. Each roller 16 is rotatably connected to a fixed shaft via a deep groove ball bearing, and both ends of the fixed shaft are rigidly fixed to the loading platform 15 by bolts. The surface of the roller 16 may be covered with an anti-slip rubber layer to increase the coefficient of friction with the material and prevent slippage.

[0029] The lifting device is installed on the base frame structure 1 and is used to drive the loading platform 15 to slide up and down along the two vertical channel steel structures 2. Specifically, the lifting device includes a drive cylinder 11, which is fixedly connected to the base frame structure 1. The drive cylinder 11 is existing technology, and a suitable model of drive cylinder 11 is selected from the market according to the actual situation. This application takes the model SC100*1000 as an example. The drive cylinder 11 has two air ports, which are respectively connected to two air lines of an external air supply device. Typically, the external air supply device is an air compressor. The compressed air it produces is filtered and pressure regulated before being switched on and off by a solenoid valve to drive the piston rod to extend and retract, thereby controlling the up and down movement of the sprocket seat 8. The sprocket seat 8 is fixed to the piston rod of the drive cylinder 11 by screws. The sprocket seat 8 is provided with a U-shaped limiting groove 803, which divides the sprocket seat 8 into a first support part 801 and a second support part 802. The first support part 801 and the second support part 802 are symmetrically provided with locking grooves 804. The sprocket 7 is locked and fixed on the sprocket seat 8 by the locking grooves 804 and the locking nut 9. The sprocket 7 has an embedded bearing, and a sprocket shaft 10 is connected to the bearing. Both ends of the sprocket shaft 10 are provided with external threads. This design allows the sprocket 7 to rotate flexibly on the sprocket shaft 10 via the bearing. Simultaneously, a locking nut 9 securely fixes the sprocket 7 to the sprocket shaft 10, preventing axial movement during rotation and ensuring stability during the lifting process. The sprocket 7 is mounted on a U-shaped limiting groove 803 via the sprocket shaft 10 and is fixedly connected to the locking grooves 804 of the first support part 801 and the second support part 802 by the locking nut 9. This structural design makes the installation and disassembly of the sprocket 7 more convenient. Simultaneously, it ensures the stable fixation of the sprocket 7 on the sprocket seat 8, improving the reliability of the lifting device; the chain 6, one end of which is fixedly connected to the first crossbeam structure 3 through a connector. It should be noted that the connector is provided with an external thread structure. The first crossbeam structure 3 is provided with a through hole. After the external thread structure of the connector passes through the through hole, the connector is fixedly connected to the first crossbeam structure 3 with a nut. The other end of the chain 6 is fixedly connected to the loading platform 15 through a connecting seat 12. The chain 6 passes around the sprocket 7 and drives the sprocket seat 8 to change the position of the sprocket 7 through the drive cylinder 11, thereby driving the loading platform 15 to rise and fall.

Those skilled in the art should understand that this application is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this application; all such changes and modifications fall within the scope of the claims.
