The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described.
Adopt novel all-hydraulic drill as shown in Figure 1, complete machine is made up of pumping plant, operating desk, support frame, frame, drilling tool, unit head six major parts.Pumping plant converts electrical energy into mechanical energy by motor, by the high-pressure oil pump group mechanical energy is converted to the hydraulic pressure energy again, for rig provides revolving force and propulsive force; High-pressure oil pipe on the operating desk has two parts, and a part is the usefulness that is connected to each other of each assembly on the operating desk; Outer each assembly of another part and operating desk is connected, oil inlet pipe is connected with pumping plant with oil return pipe, working tubing respectively with unit head on hydraulic motor be connected with propelling oil cylinder on the frame; Have 3 operator handles on the operating desk, the wherein rotating of rotary manipulation handgrip control motor, the operator of normally advancing and retreat is the normal advance and retreat of control propelling oil cylinder, and the fast advance and retreat operator is the fast advance and retreat of control oil cylinder.Frame mainly is made up of oil cylinder, hydraulic quick coupler, planker, Rack Body, guide rail etc.; The oil cylinder cylindrical shell is connected with Rack Body, and piston rod is connected with planker, and unit head is installed on the planker.When giving oil extraction to oil cylinder, planker, oil cylinder be the front and back motion on guide rail, realizes that unit head moves forward and backward.Drilling tool is made up of drilling rod and drill bit, is used for boring and deslagging.Unit head mainly is made up of three big parts such as hydraulic motor, housing, water pigtail assemblies, and its effect is that hydraulic pressure can be converted into mechanical energy, provides moment of torsion with rock cutting (coal) by drilling rod for drill bit.
Employing by advance oil cylinder 7, pilot operated directional control valve 8, sequence valve 9, from the pressure oil P1 of hydraulic motor, enter the hydraulic system of the compositions such as pressure oil P2 that advance oil cylinder 7, rig is had prevent the card rotating function automatically, guarantee that rig is in drilling process, run into special geological condition, the rig load increases, and when the card commentaries on classics occurring, unit head, drilling rod is retreated; After load reduces, unit head, drilling rod are advanced again automatically, continue to creep into.
