The guide mechanisms 2 are two groups and are symmetrically arranged on the opposite sides of the upright post 1, one group is a main guide mechanism 6, and the other group is a follow-up guide mechanism 7. The driving lifting frame 3 is formed by connecting two L-shaped bent plate bodies into an integral driving lifting frame 3. The driving motors 4 are arranged in two groups and symmetrically arranged on the opposite outer sides of the upright post 1, the driving motors 4 are connected to the motor mounting frame 9 through flanges 8, and the motor mounting frame 9 is fixed on the upright post 1 through a mounting plate 10.

The driving motor 4 drives the driving lifting frame 3 to lift on the main guide mechanism 6 and the follow-up guide mechanism 7 through the double synchronous belt mechanism 5, and the driving lifting frame 3 is further respectively provided with a braking assembly for braking and positioning.

The main guide mechanism 6 has a specific structure:

the main guide mechanism 6 is composed of a guide rail mounting plate 19, parallel guide rails 20 and guide wheels 21, the two parallel guide rails 20 are fixedly mounted on the upright post 1 through the guide rail mounting plate 19, the four guide wheels 21 are respectively and symmetrically mounted at four corners of one side of the driving lifting frame 3 through guide shafts and are rotatably connected with the driving lifting frame 3, grooves 22 are respectively arranged on wheel bodies of the four guide wheels 21, and the two parallel guide rails 20 can be clamped through the grooves 22. The main guide mechanism 6 can drive the lifting frame 3 to perform lifting motion along the parallel guide rail 20, and the lifting positioning precision is ensured by the matching of the groove 22 of the guide wheel 21 and the parallel guide rail 20.

The following guide mechanism 7 has the following specific structure:

The counterweight 18 can offset most of the weight of the lifting frame 3, so that the power of the driving motor 4 driving the lifting frame 3 is reduced, the lifting speed of the lifting frame 3 is increased, and the lifting efficiency is improved.

The specific structure of the brake assembly is as follows:

the brake assembly is composed of a brake valve 32, a brake valve mounting bracket 33, a brake caliper 34, an abutting block 35, a friction plate 36 and a brake rail 37; the brake valve 32 is fixedly mounted on the bottom of the driving lifting frame 3 through a brake valve mounting bracket 33, the brake caliper 34 is rotatably connected with the driving lifting frame 3, one end of the brake caliper 34 is provided with an abutting block 35, the abutting block 35 can abut against the extending end of the brake valve 32, the other end of the brake caliper 34 is provided with a friction plate 36, and the friction plate 36 can abut against a brake rail 37 mounted on the upright post 1. When the double synchronous belt lifting mechanism is in failure or power failure, the brake assembly acts immediately, the brake caliper 34 clamps the brake track 37, and a friction force which is large enough to overcome the gravity of the lifting mechanism is generated, so that the lifting mechanism is prevented from falling, and the mechanism is protected.

The working principle of the double synchronous belt lifting mechanism is as follows:

when the double-synchronous belt lifting mechanism is used, firstly, goods to be lifted are placed on the driving lifting frame 3, and the driving lifting frame 3 forms a load under the action of the gravity of the goods; then, the two driving motors 4 are started, and the two driving motors 4 synchronously rotate and simultaneously drive the driving wheels 13 of the two groups of double synchronous belt mechanisms 5 to synchronously rotate; because the driving wheels 13 and the driving wheels 14 are in transmission connection through the closed-loop synchronous belts 16, the driving wheels 13 of the two groups of double synchronous belt mechanisms 5 synchronously rotate, and meanwhile, the driving wheels 14 of the two groups of double synchronous belt mechanisms 5 can be driven to synchronously rotate through closed-loop synchronization; because the driving wheel 14 and the driven wheel 15 are fixedly sleeved on the same rotating shaft 12, the driving wheels 14 of the two groups of double synchronous belt mechanisms 5 can drive the driven wheels 15 of the two groups of double synchronous belt mechanisms 5 to synchronously rotate while synchronously rotating; because the open-loop synchronous belt 17 bypasses the driven wheel 15, one end of the open-loop synchronous belt is fixedly connected with the driving lifting frame 3, the other end of the open-loop synchronous belt is fixedly connected with the balancing weight 18, and the balancing weight 18 can balance partial load, so that the driven wheel 15 of the two groups of double-synchronous belt mechanisms 5 can synchronously rotate and simultaneously drive the driving lifting frame 3 to lift on the main guide mechanism 6 and the follow-up guide mechanism 7.

When the double synchronous belt lifting mechanism needs to brake and position the driving lifting frame 3, the brake assembly works, firstly, the brake valve 32 is started, and the extending end of the brake valve 32 extends out to be abutted against the abutting block 35; the brake caliper 34 swings relative to the drive lift frame 3 while the projecting end of the brake valve 32 abuts against the abutment block 35, and the friction plate 36 at the other end of the brake caliper 34 abuts against the brake rail 37 to perform brake positioning.

In order to ensure that the closed-loop timing belt 16 is in a tensioned state, an adjusting mechanism 26 for tensioning the closed-loop timing belt 16 is further arranged on the upper portion of the mounting plate. In order to adjust the positions of the rotating shaft 12 and the driving wheel 14 and the driven wheel 15 on the rotating shaft 12, an up-down adjusting mechanism 27 and a front-back adjusting mechanism 28 capable of adjusting the position of the rotating shaft 12 are further arranged on the mounting frame. In order to limit the maximum descending stroke of the driving lifting frame 3, the upright 1 is further symmetrically provided with a lower limiting device 31 capable of limiting the maximum descending point of the driving lifting frame 3.

On the basis of the technical scheme, in order to realize automatic control by matching with a full-automatic logistics storage system, the double-synchronous belt lifting mechanism further comprises an electronic belt scale and an electric control computer; the electronic belt scale and the electronic control computer are not shown. The electronic belt scale can be fixedly arranged between the driving lifting frames 3, the electronic belt scale is in information transmission connection with the electric control computer, and the electric control computer is in control connection with the two groups of driving motors 4. The electronic belt scale is used for weighing the load-bearing goods, the weighing result is fed back to the electric control computer, the electric control computer calculates the output power required by the dual-drive motor 4 according to the load weight and the difference value of the balancing weight 18, and the output power required by the dual-drive motor 4 controls the output of the drive motor 4. When the difference between the load weight and the counterweight block 18 is small, the electric control computer controls the driving motor 4 to operate at a low rotating speed so as to ensure the stability of the goods in the lifting process and avoid generating larger inertia; when the difference between the load weight and the counterweight block 18 is large, the electric control computer controls the driving motor 4 to operate at a high rotating speed, the driving power is matched with the counterweight block 18 to balance the load weight, the stability of the heavy-load goods in the lifting process is ensured, and the generation of large inertia is avoided. In addition, in order to detect the lifting position of the lifting frame 3, a photoelectric sensor for detecting the lifting position of the lifting frame 3 is also arranged on the upright post 1.
