Problems solved by technology

[0002] In the prior art, the well-known technologies are JKB series winches and JTP(B) series winches widely used in mines at present. These winches all use JR and JBR series slip ring motors. The acceleration and deceleration of the start of the winch is achieved by connecting a resistor to the slip ring rotor and changing the resistance value of the resistor. However, it is difficult to implement the explosion-proof requirements of the resistor, which makes the slip ring motor unable to meet the requirements of many industries such as mines. The required explosion-proof requirements, therefore, limit the range of use of this type of winch, which is the deficiency of the existing technology

Abstract

The present invention provides a technical scheme of hoisting and transporting winch in mine hoisting and transporting mechanical equipment. Parking safety brake, one end of the output shaft of the reduction box of the reduction box described in this plan is connected to the input shaft of the slow planetary transmission box, the other end is connected to the input shaft of the fast planetary transmission box, and the output shaft of the slow planetary transmission box is connected to the slow transmission box The input shaft of the slow gearbox, the output shaft of the fast planetary gearbox is connected to the fast gearbox input shaft of the fast gearbox, the slow gearbox output gear of the slow gearbox and the fast gearbox output gear of the fast gearbox are connected to the drum at the same time , the drum is positioned by the drum support shaft; there is a slow running brake on the slow planetary transmission box, and a fast running brake on the fast planetary transmission box.

Description

Technical field: [0001] The invention relates to a mine hoisting and transportation machinery and equipment, in particular to a hoisting and transportation winch. Background technique: [0002] In the prior art, the well-known technologies are the JKB series winches and JTP(B) series winches, which are currently used in large quantities in mines. These winches adopt JR and JBR series slip ring motors and pass through the gearbox to drive the drum. The transmission system The acceleration and deceleration of the winch start is achieved by connecting a resistor in the slip ring rotor and changing the resistance of the resistor. It is difficult for the resistor to implement explosion-proof requirements, which makes the slip ring motor unable to meet the requirements of many industries such as mines. The required explosion-proof requirements, therefore, limit the scope of use of this type of winch, which is a shortcoming of the existing technology. Summary of the invention: [0003]...
