Problems solved by technology

[0002] Existing outrigger rock bolt rigs mostly use hydraulic oil pumps to drive the bolts in coal mine roadways, but the use of such oil pumps will lead to higher production costs, easy to cause environmental pollution during construction, and greater power loss
In order to overcome this defect, the outrigger bolter driven by the emulsion pump also has certain defects. The separation of the emulsion pump and the bolter makes it very inconvenient to carry, and the peripheral equipment of the pipeline is prone to danger. The pipeline is fixed so that the height of the anchor rod cannot be adjusted freely due to the limitation of the liquid pump

Abstract

The invention provides a supporting leg-adjustable roof bolter. The supporting leg-adjustable roof bolter includes a telescopic supporting leg; a bottom seat is arranged on the bottom of the telescopic supporting leg; a flow allocator is arranged on the top of the telescopic supporting leg; a liquid pump is arranged on one side of the telescopic supporting leg; a fixing ring is arranged on the telescopic supporting leg; the liquid pump is fixed on the telescopic supporting leg through the fixing ring; the top end of the liquid pump has a liquid feeding pipe; a free end of the liquid feeding pipe is inserted in to the flow allocator; a hollow rotation shaft is arranged on the top of the flow allocator; a fixing member is arranged on the top of the rotation shaft; a machine body is fixed onthe fixing member; the machine body communicates with the flow allocator through the rotation shaft; an output end of the machine body has a driller head, and the other end of the machine body has anoperation arm; a cavity is formed in the operation arm, and the cavity formed in the operation arm communicates with the machine body; a control valve is arranged under the operation arm; an output end of the control valve has a liquid discharging hose; and a free end of the liquid discharging hose is connected to the liquid pump. A user can easily adjust the height of the anchor bolt according tothe working demand; and the supporting leg-adjustable roof bolter is small in size, and is easy to carry.

Description

technical field [0001] The invention belongs to the field of rock bolt drilling equipment, and in particular relates to an adjustable outrigger type rock bolt drilling machine. Background technique [0002] Most of the existing outrigger rock bolt rigs use hydraulic oil pumps to drive the bolts in coal mine roadways. However, the use of such oil pumps will lead to higher production costs, easy to cause environmental pollution during construction, and greater power loss. In order to overcome this defect, the outrigger bolter driven by the emulsion pump also has certain defects. The separation of the emulsion pump and the bolter makes it very inconvenient to carry, and the peripheral equipment of the pipeline is prone to danger. The pipeline is fixed so that the height of the anchor rod cannot be adjusted freely due to the limitation of the liquid pump. Contents of the invention [0003] The problem to be solved by the present invention is to provide an adjustable outrigger...
