Embodiment Construction

[0035] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The coal mine drilling rig hydraulic winch speed changer provided by the present invention comprises a lower box body 2 and an upper box body 1, which are stacked from bottom to top and connected by bolts, spring washers and nuts to form the box body. An input mechanism 41, an output mechanism 40, and a shift actuator 39 are arranged inside the casing, and a shift control mechanism 42 is arranged outside the casing. The input mechanism 41 is used for input power and high-speed rotation speed; the output mechanism 40 is used for output torque and low-speed rotation speed; the shift actuator 39 is used to change the transmission ratio of the input mechanism and the output mechanism, and the shift control mechanism 42 is used for manipulating the shift execution Mechanism 39 realizes automatic gear shifting function.

Abstract

The invention discloses a speed changer for a coal mine drilling rig hydraulic winch. The speed changer comprises an input mechanism, an output mechanism, a gear shifting executing mechanism and a gear shifting control mechanism, wherein the input mechanism, the output mechanism and the gear shifting executing mechanism are arranged in a box body, and the gear shifting control mechanism is arranged outside the box body. The gear shifting control mechanism comprises a programmable logic controller, an electric control cabinet and a frequently-used solenoid valve, and automatic gear shifting is achieved by changing the working state of a piston. Gear sets meshed with each other are arranged on an input shaft and an output shaft, a double-connecting sliding gear is arranged between the gear sets, the tool withdrawal groove of the double-connecting sliding gear is matched with a shifting fork, the gear shifting control mechanism effectively controls the gear shifting executing mechanism, and the gear shifting and the automation of the gear shifting are achieved.

Description

technical field [0001] The invention relates to a transmission mechanism used in mechanical equipment, in particular to a coal mine drilling rig hydraulic drawworks transmission equipped with numerical control technology. Background technique [0002] The purpose of the coal mine drilling rig hydraulic winch is: (1) The coal mine drilling rig hydraulic winch can be used as a column return winch when it is slow, and it can be used as a dispatching winch when it is fast; (3) It can be used for dispatching marshalled mine cars on the loading station of mining face and tunneling face, or for mine car dispatching, material transportation, back column topping, various electromechanical equipment in coal mine underground roadway It can also be used for auxiliary transportation work such as relocation and recovery of metal pillars sunk into the bottom plate or stuck by gangue on various coal mining working faces. [0003] The main research object of the invention is the key compone...
