Description

Technical Field

[0001] This utility model relates to the field of cargo conveying devices, and in particular to a vertical lifting cargo conveying device with high load capacity and long stroke. Background Technology

[0002] A vertical lift is a device used for vertical transportation of materials or personnel. It is widely used in construction, mining, warehousing, and industrial production. Its main function is to use an electric drive system to lift the carrier vertically, thereby achieving fast and stable transportation of materials or personnel. The structure of a vertical lift includes guide rails, a carrying platform, a drive system, and a control system. During operation, the carrying platform moves up and down on the guide rails, and the drive system provides power through an electric motor. Depending on the application, vertical lifts can be divided into cargo lifts and personnel lifts. Cargo lifts are usually used for vertical material handling in warehouses and factories, while personnel lifts are more often used for personnel transportation in high-rise buildings.

[0003] The advantages of vertical lifts lie in saving space, improving transportation efficiency, and enabling the transport of large volumes of materials or personnel within a limited space.

With the development of technology, the design of vertical lifts is becoming increasingly intelligent, and they can be combined with automation systems and monitoring systems to further improve the convenience and efficiency of use.

[0004] When using a vertical lift to transport goods, it needs to move up and down repeatedly. The loading platform moves stably through the action of guide rails. However, due to the long-term contact between the guide rails and the loading platform, friction will be generated. Furthermore, the vertical lift is very high, making it impossible to manually lubricate the rails and the loading platform. As a result, the guide rails and the loading platform will wear and become damaged, affecting the smoothness of the loading platform's movement.

[0035] Reference Figure 1 , Figure 2 , Figure 5The alignment component includes two limiting plates 15 and four housings 16. The limiting plates 15 are externally slidably connected to the upper side of the loading platform 3. The housings 16 are externally fixedly connected to the inside of the loading platform 3.

Springs 19 are fixedly connected to the outside of the slide plates 18. Baffles 20 are slidably connected inside the housings 16. A limiting piece 21 is fixedly connected to the top of the housings 16. The limiting plates 15 are used to stabilize the goods and prevent them from falling. The housings 16 are used to connect and protect internal parts. The insert rods 17 are inserted into the limiting plates 15 to fix them in place. The slide plates 18 bear the thrust of the springs 19 and drive the insert rods 17 to move synchronously. Springs 19 are used to drive the insert rods 17... The baffle 20 is used to block the outlet of the insertion rod 17 to prevent the insertion rod 17 from automatically resetting. The limiting piece 21 is used to limit the movement distance of the baffle 20 to prevent it from falling off. The second spring 19 is externally fixed to the inner wall of the outer shell 16 and internally sleeved on the outside of the insertion rod 17 to keep the second spring 19 stable.

The bottom of the baffle 20 and the top of the slide plate 18 abut against each other to control the timing of the baffle 20 falling.

[0036] Working Principle: When using this device to transport goods, first adjust the distance between the two limiting plates 15 according to the size of the goods. By pulling the insert rod 17, the insert rod 17 drives the slide plate 18 to compress the second spring 19, causing the insert rod 17 to retract into the outer shell 16 and disengage from the limiting plate 15. At the same time, the baffle 20 will automatically fall into the outer shell 16, blocking the outlet of the insert rod 17. At this time, the limiting plate 15 is unlocked. Then, start adjusting the position of the limiting plate 15. When it is adjusted to the appropriate position, under the limit of the limiting piece 21, pull the baffle 20. At this time, the second spring 19 will immediately push the slide plate 18 to reset, causing the insert rod 17 to re-insert into the limiting plate 15, fixing the limiting plate 15 and realizing the adjustment. At this time, the hoist can be controlled to start working. By placing the goods on the loading platform 3, the internal drive system starts sliding. The guide rail 2 moves up and down under its limit, causing the shaft to rotate and transport the goods. When the hoist is used for a long time, friction will occur between the guide rail 2 and the loading platform 3. At this time, lubricating oil needs to be added. By manually opening the valve 12, the spring 6 will instantly push the piston 7 to drive the push rod 8 to reset. Then, the loading platform 3 is controlled to move. Through the action of the rack 4, the gear 13 drives the cam 14 to rotate. The cam 14 will push the push rod 8 to compress the piston 7 and spring 6. The piston 7 moves back and forth and cooperates with the two one-way valves 10 to transport the lubricating oil in the oil tank 11 along the pipe 9 to the friction point between the loading platform 3 and the guide rail 2 to achieve lubrication. When it is not necessary to add oil, simply close the valve 12 and push the piston 7 to the front to stop pumping oil. At this time, the goods can continue to be transported, saving time and effort.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
