[0036] Driving assembly 3 is arranged at the position inside the curing barn frame structure 1, the driving assembly 3 includes hydraulic rod 18, the telescopic end of the hydraulic rod 18 is fixedly connected with sliding push rod 19, the top of the sliding push rod 19 is arranged with pulley 20, the upper part of the pulley 20 is arranged with sliding rope 21, the lower end of the sliding rope 21 is fixedly connected with the curing barn frame structure 1 through fixing seat 22, the other end of the sliding rope 21 is fixedly connected with the lifting frame group 2 through the upper part of the pulley 20 by means of bolt;

[0037] It can be known that the driving assembly 3 is the power source of the whole device. The driving assembly 3 drives the sliding push rod 19 and the pulley 20 to move up and down through the reciprocating movement of the hydraulic rod 18. Such movement will make the sliding rope 21 move, and one end of the sliding rope 21 is fixedly connected with the curing barn frame structure 1, so that the other end of the sliding rope 21 drives the lifting frame group 2 to move up and down. The design of such hydraulic system can provide reliable and efficient power transmission, effectively driving the operation of the device.

[0038] Limiting assembly 4 is arranged at the position of the upper part inside the curing barn frame structure 1, the limiting assembly 4 includes linkage rod 23, the inside of the curing barn frame structure 1 and the positions corresponding to the lifting connecting rod one 12 and the lifting connecting rod two 14 are arranged with linkage rod 23, the end part of the linkage rod 23 is fixedly connected with the curing barn frame structure 1, the end part of the side of the linkage rod 23 is fixedly connected with limiting baffle 24, the limiting baffle 24 is provided with transverse sliding slot, the end part of the two linkage rods 23 of the end part of the curing barn frame structure 1 is fixedly connected with movable switch 25, the telescopic end of the two movable switches 25 of the same side is transversely fixedly connected with sliding round rod 26, the sliding round rod 26 is located in the transverse sliding slot of the limiting baffle 24; the hook-shaped iron sheet 13 is connected with the sliding round rod 26.

[0039] It can be known that the limiting assembly 4 mainly relies on the movable switch 25, the end part of the lifting connecting rod one 12 and the lifting connecting rod two 14 is fixedly connected with the hook-shaped iron sheet 13, when the lifting frame group 2 rises, the hook-shaped iron sheet 13 can drive the sliding round rod 26 to move, the sliding round rod 26 can drive the switch piece of the movable switch 25 to stretch and contract, the switch piece of the movable switch 25 is clamped after being compressed for the first time, so as to be fixed, and is released after being compressed again, so as to be opened.

[0040] Wherein, the activity switch 25 is a mature existing technology, when the activity switch 25 is compressed for the first time, the internal mechanical structure such as spring, buckle and the like will be deformed. This deformation causes one or more components such as buckle inside the switch to move to the locking position, thereby jamming the switch, making it remain in a fixed state. When the activity switch 25 is compressed again, the internal mechanical structure will be further deformed, thereby releasing the previously locked components. This allows the switch to be released and returns to its initial state, thereby releasing the previously fixed function, the activity switch 25 is widely used in many fields, therefore, in this application will not be described in detail.

It can be known that the end portions of the lifting linkage one 12, the lifting linkage two 14 and the lifting linkage three 15 are vertically slidably connected with the slide rail one 9 through the guide wheel one 17, so that the lifting frame group 2 is guided and limited during lifting, thereby improving the stability of the lifting frame group 2 during movement.
