hoist

Elevators are large mechanical equipment that transport by changing the potential energy. The following is a detailed introduction about the hoist:

Structural composition:

Rack: As the supporting structure of the entire equipment, it ensures the stability and firmness of the equipment during operation, and provides an installation foundation for other components.

Drive device: usually composed of a motor, reducer, coupling, etc., providing power for the hoist and driving its operation. The power and speed of the motor are selected according to the specific requirements of the hoist.

Traction components: Common ones include steel wire ropes, ring chains, plate chains, tape, etc. Steel wire rope has high strength and flexibility, suitable for various types of hoists; The sturdy chain structure is suitable for conveying materials with high abrasiveness; Plate chain is suitable for lifting machines with large lifting capacity; Adhesive tape is commonly used for conveying materials such as powders and small particles.

Hopper (or car, basket, etc.): used for loading and conveying materials. The shape, size, and material of the hopper depend on the characteristics of the conveyed material and the type of elevator. For example, there are various forms of hoppers for bucket elevators, such as deep hoppers, shallow hoppers, pointed hoppers, etc., to meet different material conveying needs.

Tensioning device: used to adjust the tension of the traction component, ensure sufficient friction between the traction component and the driving device, prevent slipping, and ensure the normal operation of the hoist.

Guiding device: It guides the hopper or car to run stably in the vertical direction, preventing shaking, deviation, and other situations during operation.

Working principle: The motor drives the driving device to operate, and the driving device transmits power to load-bearing components such as hoppers or cars through traction components, causing the load-bearing components to move up or down vertically along the frame, thereby achieving the lifting and conveying of materials or personnel.

Category:

Bucket elevator: It is a mechanical conveying equipment with a fixed device, mainly suitable for continuous vertical lifting of powdery, granular and small block materials. According to the speed of the hopper operation and the different unloading methods, it can be divided into three forms: centrifugal unloading, gravity unloading, and mixed unloading.

Mine hoist: It is a large lifting mechanical equipment used to lift personnel, ore, coal, etc. in mines. The mine hoist has the characteristics of large lifting capacity, high speed, and high safety requirements. Its structure is relatively complex, including the main shaft, drum, main bearing, rope adjusting clutch, reducer, depth indicator, and brake, and other main components.

Hydraulic hoist: It is a non scissor hydraulic lifting platform suitable for transporting goods between two or three floors of industrial plants, restaurants, and eateries. The lowest height of its tabletop is relatively low, with various forms, smooth operation, and simple and reliable operation.

Vertical vibration hoist: composed of a lifting groove, a vibration motor, a vibration reduction system, and a base. Using a vibration motor as the vibration source, the material is thrown up in the lifting tank while moving upwards. It can vertically transport solid materials in powder, block, and short fiber forms (except for those with viscosity and easy clumping), and also perform drying, cooling, and other functions on the material.

characteristic:

High lifting height: It can achieve the lifting of materials or personnel at a higher height to meet the needs of different places.

Strong conveying capacity: It can continuously and efficiently transport large amounts of materials or personnel, improving production efficiency.

High operational reliability: After reasonable design and manufacturing, the hoist operates stably with low failure rate, ensuring long-term normal operation.

Wide applicability: Depending on the characteristics of different materials, conveying requirements, and working environments, different types of elevators can be selected, which have strong applicability.
