The counterweight is attached to the transmission belt between the drive shaft and the end of the transmission belt. The drive shaft, the mounting platform, and the counterweight are all equipped with directional pulleys corresponding to the transmission belt.

A drive mechanism (3) for the mounting platform (2) to rise inside the frame (1) is also installed on the frame (1). The frame (1) comprises at least four vertical support columns (101), and a reinforcing crossbeam (102) is installed between the support columns (101) via clamps (103).

[0034] The drive mechanism (3) includes a drive component (31), a drive shaft (32), a transmission belt (33), and a counterweight (34); the drive shaft (32) is connected to the drive component (31) and is mounted on one side of the top of the frame (1) through a bearing seat; the beginning end of the transmission belt (33) is mounted on the top of the frame (1) away from the drive shaft (32); the counterweight (34) is located on the same side of the frame (1) as the drive shaft (32) and is located outside the frame (1);

[0035] The transmission belt (33) extends downward across the mounting platform (2) from the beginning and then goes upward around the drive shaft (32) and connects to the top of the frame (1). The counterweight (34) is hooked on the transmission belt (33) between the drive shaft (32) and the end of the transmission belt (33). The drive shaft (32), the mounting platform (2), and the counterweight (34) are all equipped with a directional pulley (38) corresponding to the transmission belt (33). The counterweight (34) is hooked on the transmission belt (33) through the directional pulley (38).

[0036] Specifically, guide rails (36) for guiding the counterweight (34) to rise and fall are vertically installed on the two columns (101) on one side of the counterweight (34) via mounting parts (35), and limit wheels (37) adapted to the guide rails (36) are installed on the counterweight (34).

[0037] Furthermore, the mounting component (35) is provided with a limiting groove for engaging the guide limiting rail (36), and the limiting grooves on the two mounting components (35) on the two columns (101) are symmetrically arranged facing both sides of the counterweight (34).

[0038] The guide rail (36) has a V-shaped horizontal cross section.

[0039] Furthermore, there are two transmission belts (33), and the two transmission belts (33) are symmetrically installed about the central axis of the vertical drive shaft (32) of the frame (1).

[0040] Specifically, the mounting platform (2) includes at least a rectangular base frame, the two sides of the rectangular base frame parallel to the transmission belt (33) are made of hollow tubes (21), the deflecting wheels (38) on the mounting platform (2) for turning the transmission belt (33) are installed at both ends of the hollow tube (21), and the transmission belt (33) passes through the hollow tube (21) through the deflecting wheels (38) on the same hollow tube (21);

[0041] A gap is formed between the bottom horizontal tangent of the deflector wheel (38) and the bottom of the inner wall of the hollow tube (21) through which the useful transmission belt (33) passes.

[0042] It plays a role in stably supporting the mounting platform 2, further ensuring the stability of the lifting and lowering of the mounting platform 2.

[0043] Furthermore, in this device, safety mechanisms (4) can be installed on the side of the frame (1) parallel to the transmission belt (33) corresponding to different floors, and a fall protection mechanism (5) is provided between the frame (1) and the mounting platform (2); wherein the safety mechanism (4) and the fall protection mechanism (5) have been disclosed in the prior patent entitled "Vertical Conveying Device" with patent number "202221717458.5", and will not be described in detail here;

[0044] The column (101) is installed by multiple splicing segments (1011) and connectors (1012). The connectors (1012) are inserted into one end of two adjacent splicing segments (1011), and the connectors (1012) are connected and fixed to the splicing segments (1011) by bolts.

[0046] When using this utility model:

[0047] After the material passes through the safety mechanism (4) and enters the loading platform (2), the drive unit (31) starts to rotate the drive shaft (32). The rotation of the drive shaft (32) can cause the reversing wheel (38) to drive the transmission belt (33) to move. When the transmission belt (33) moves towards the counterweight (34), the loading platform (2) connected to the transmission belt (33) through the reversing wheel (38) will rise directly. Conversely, when the drive shaft (32) starts in the opposite direction, the loading platform (2) will carry the material down. When the loading platform (2) moves Once in the correct position, the sensor will detect the location of the mounting platform (2); the running trajectory of the transmission belt (33) is restricted by the deflector (38) and the hollow tube (21), which effectively avoids problems such as derailment and mutual wear of the transmission belt (33). Compared with the use of a drum to wind up the wire rope to drive the mounting platform (2) to rise, this effectively reduces the problem of the wire rope coming off the drum and wear between the winding ropes, thereby reducing the probability of maintenance and eliminating the need to install a maintenance platform on the top of the equipment.

[0048] The column (101) is spliced ​​with splicing sections (1011) and connectors (1012), and the column (101) is connected to each floor slab through connecting plates and bolts. This can reduce the vertical load of the column (101), thereby reducing the requirements for the installation site, and making the equipment more convenient to transport and transfer.

[0049] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made to the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
