1、 Overview of rack and pinion screw elevator:
The rack and pinion screw lift is a basic lifting component with a load-bearing capacity of 2.5-50Tworm screw liftCompared with the main advantages, it has high efficiency, long service life, and easy adjustment of reduction ratio. At the same time, it has many advantages such as compact structure, small volume, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, and high reliability. It has multiple functions such as lifting, landing, propulsion, and flipping, and can accurately control and adjust the height of lifting or propulsion according to a certain program. It can be directly driven by an electric motor or other power source. It can also be done manually. The rack and pinion screw elevator has a high input speed of 500r/min and a high lifting speed of 2.7m/min. There are different structural styles, and the height is manufactured according to the user's requirements. This device is self-locking. After improvement by our company's technical department, its quality and performance can replace similar products imported from abroad.
2、 Structural type:
Type 1- The screw moves axially.
Type 2- The screw rod rotates and the nut on the screw rod moves axially
Each structural form of the elevator is divided into two assembly types
Type A - The screw (or nut) moves upwards
B-type - screw (or nut) moves downwards
3. Screw head type:
The screw head of Type 1 structural type is divided into four types: I (cylindrical type), II (flange type), III (threaded type), and IV (flat head type)
The screw head of Type 2 structural type is divided into two types: I (cylindrical type) and III (threaded type)
4. Specifications:
Divided by lifting force into eight types: 2.5, 5, 15, 20, 35, and 50 × 10KN
5. Transmission ratio:
Elevators are divided into two types based on lifting speed: normal and slow. Slow speed is represented by l, while normal speed is not labeled.
6. Protection of screw rod:
The protection of the screw rod of Type I elevator is divided into: basic type, anti rotation transformation (F), and type with protective cover (z)
The protection of type 2 elevator screws is divided into basic type and shielded type (z)
3、 Application scope
This product can be widely used in various industries such as machinery, metallurgy, construction, water conservancy, chemical engineering, culture and health. For example, heavy pressure fastening devices such as lifting tables, flipping devices, and plastic processing machines for mechanical processing; Installation and maintenance of climbing ladders and tool lifting frames, as well as locomotive maintenance lifting platforms; Adjustment of clearance between rolling mill tracks and adjustment of the feeding position of pipes or plates; Casting molds or concrete shapes; Used for adjusting electrodes and hot liquid casting in smelting; Templates for mobile devices and composite products in architecture, including adjustable windows, walls, enclosures, etc; In terms of cultural hygiene, the stage can be raised and lowered, the height of the swimming pool floor can be adjusted, and the height of the operating table can be adjusted; Gates and protective plates used in water conservancy for reservoirs; Used in scientific research for sports that cannot be adjusted manually. Specially suitable for large lifting platforms.
