Description

Technical Field

[0001] This utility model relates to a sprocket steel belt lifting mechanism. Background Technology

[0002] Currently, automatic telescopic mechanisms mainly come in the following forms: hydraulic telescopic, pneumatic telescopic, electric screw-driven telescopic, and electric rack and pinion telescopic, among which:

[0003] Hydraulic telescopic movement utilizes the pressure transmission of hydraulic oil within a closed cylinder to achieve telescopic motion. However, due to the large size of the cylinder and the high sealing requirements, hydraulic telescopic movement is mainly used in large equipment and can only achieve single-stage telescopic movement, not multi-stage telescopic movement.

[0004] Pneumatic telescopic movement uses compressed air as a power source to pressurize or depressurize a closed cylinder, thereby achieving the extension and retraction of a piston. However, pneumatic telescopic movement requires high cylinder sealing performance and is a single-stage movement, unable to achieve multi-stage movement.

[0005] Electric screw-driven telescopic movement refers to a system where a screw, screw nut, and telescopic component are connected. When a motor drives the screw to rotate, the screw nut moves along the screw's axis, thereby causing the telescopic component to extend or retract. Electric screw-driven telescopic movement has the following drawbacks: the length and strength of the screw determine the telescopic distance, resulting in a small telescopic ratio.

[0006] Electric rack and pinion telescopic mechanism refers to a mechanism where a gear, rack, and telescopic component are connected. When a motor drives the gear to rotate, the rack moves along the gear's axis, thereby causing the telescopic component to extend or retract. Electric rack and pinion telescopic mechanisms have the following drawbacks: the length and strength of the rack determine the telescopic distance, resulting in a small telescopic ratio.

[0054] A sprocket and steel belt lifting mechanism comprises the following components:

[0055] Casing 6;

[0056] The motor bracket 8 is fixed to one side of the housing 6;

[0057] The sprocket motor mounting bracket 22 is L-shaped and is fixedly connected to the motor bracket 8.

[0058] The sprocket motor 2 is fixed on one side of the housing 6. The drive shaft of the sprocket motor 2 passes through the sprocket motor mounting bracket 22 and the housing 6 in sequence and is inserted into the sprocket motor mounting base 21. The outer boss of the sprocket motor mounting base 21 is sleeved with the sprocket 3.

[0059] The recycling wheel motor mounting plate 11 is fixed to one side of the housing 6, and the drive shaft of the recycling wheel motor 1 passes through the recycling wheel motor mounting plate 11 and the housing 6 in sequence and is inserted into the recycling wheel 4.

[0060] The telescopic rod 7 is composed of multiple hollow square tubes and corresponding plugs. The bottom end of the telescopic rod 7 is welded to the housing 6.

[0061] The 301 perforated steel strip 9 has holes that are adapted to the teeth of the sprocket 3. One end of the 301 perforated steel strip 9 is fixed to the recovery wheel 4, and the other end of the 301 perforated steel strip 9 fits into the teeth of the sprocket 3 along the hole. The entire 301 perforated steel strip 9 extends into the interior of the telescopic rod 7, and the other end of the 301 perforated steel strip 9 is fixed to the top end of the telescopic rod 7.

[0062] Limiting blocks 5 are respectively provided at the bottom and both sides of the housing 6. A limiting groove 51 is provided in the middle of the limiting block 5. The position of the limiting groove 51 is adapted to the position of the teeth of the sprocket 3.

[0063] The microcontroller has its output terminals connected to the input terminals of the recycling wheel motor 1 and the sprocket motor 2, respectively, and is used to control the start-up, stop-start, and rotation direction of the recycling wheel motor 1 and the sprocket motor 2.

[0064] Furthermore, the motor bracket 8 is fixed to one side of the housing 6 by bolt connection.

[0065] Furthermore, the sprocket motor mounting bracket 22 is fixedly connected to the motor bracket 8 by bolts.

[0066] Furthermore, the drive shaft of the sprocket motor 2 is a semi-circular key shaft, and the sprocket motor mounting base 21 has a hole in the middle that is adapted to the drive shaft of the sprocket motor 2.

At this time, the tail of the 301 perforated steel belt 9 is retracted inward to the recovery wheel 4 to form multiple loops together.

Each section of the telescopic rod 7 has a limit switch. When the entire extension is in place, the recovery wheel motor 1 and the sprocket motor 2 stop at the same time, and the extension movement is completed.

However, this utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this utility model.
