Automatic single prop valve disassembly device

Abstract

The invention relates to an automatic single prop valve disassembly device which saves time and labor during disassembling a three-way valve. The device comprises a bracket, wherein a round pin is penetrated on the bracket, and a slide way is fixedly connected under the bracket; the slide way is internally and slidably connected with a rotating machine comprising a wagon box, and a wheel pair is arranged below the wagon box; the wheel pair is arranged in the slide way, and the wagon box is internally and fixedly provided with an electromotor; a rotating shaft is arranged on the wagon box in a relative rotation mode, and one end of the rotating shaft extends towards the bracket; a transmission wheel is arranged on the rotating shaft in a relative rotation mode and is in a transmission connection with the electromotor through a belt; a spline shaft is arranged on the transmission shaft, and a spline slide sleeve is slidably connected to the spline shaft; a return spring is sleeved on the spline shaft and arranged between the transmission shaft and the spline slide sleeve; the right side wall of a transmission wheel is fixedly connected with a driven stop pin, and the outer side wall of the spline slide sleeve is fixedly connected with a driving stop pin; an operation handle is articulated on the wagon box, and one end of the operation handle is connected with a pawl; and one end of the rotating shaft extending towards the bracket is provided with a sleeve.

Description

technical field [0001] The invention relates to a mining machine, in particular to an automatic valve unloading device for a single pillar. Background technique [0002] Now, after the common single pillar and three-purpose valve in the coal mine system are used underground, the three-purpose valve goes up the well together with the single pillar. It needs to be tested or repaired on the ground. After passing the pressure test, it is put into storage. The three-purpose valve has been used underground for a long time, and deformation and corrosion often occur. It is time-consuming and laborious to disassemble the three-purpose valve. Gas welding is commonly used, but it is easy to cause damage to the three-purpose valve. Contents of the invention [0003] The object of the present invention is to provide an automatic valve unloading device for a single pillar that saves time and effort when disassembling a three-purpose valve. [0004] An automatic valve unloading device f...
