Hydraulic bolt disassembling machine

The invention relates to a kind of hydraulic pressure bolt dismantal machine. It includes rack, carrying shaft that is fixed to the anterior and posterior bearing seats and supported by axletree. On the front end of the carrying shaft is a nut shape spindle nose. And in the center is drive gear of the carrying shaft which has side ears at its two sides. On the two sides of the rack pole are cylinder bottom and hydraulic pressure cylinder that is hinged with the fixed board of the rack, the piston pole, and the side ears. The device uses the pump station hydraulic system of the mine collecting work face as driving source, so it can loose and take down the bolt simply, fast, and easily. It supplies a special bolt disassembly device for mining. The device has high security. And it is simple to control it, so it is suited to all kind of circumstance that uses hydraulic pressure driving power, especially gas. It won't result in blasting, and can be moved simply, has good security.
