Abstract
The utility model discloses a motor load and propelling force self-adaptive hydraulic drilling machine to solve the problem of low drilling efficiency caused by manual control on rotating load and propelling force of the existing mine drilling machine. The drilling machine comprises a pump station, an operating platform, a support framework, a rack, a drilling tool, a power head and a hydraulic system. In the hydraulic system, a remote control pressure reducing valve is arranged between pressure oil P2 entering a propelling cylinder and the propelling cylinder. The remote control pressure reducing valve is provided with a load inductor that is connected with pressure oil P1 from a hydraulic motor. During the drilling process of the drilling machine, when the load of the drilling machine increases, the propelling force and propelling speed are reduced automatically, thus reducing the load of the drilling machine; when the load of the drilling machine reduces, the propelling force and the propelling speed can be automatically increased. The hydraulic drilling machine prevents the problem of low drilling efficiency caused by manual control on the load and the propelling force of the drilling machine and incapability of being suitable for the change of rock formation properties.
Description
Technical field
The utility model relates to the all-hydraulic drill that is used for mine and tunnel Drilling gas extraction hole, discharge orifice, spy water hole, gravity vent, communication aperture, cable aperture, geology hole and other engineering usefulness hole.
Background technology
In the safety and production of mine and tunnel construction, rig has important role.Rig is made up of pumping plant, operating desk, support frame, frame, drilling tool, unit head six major parts, and 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.At present, rig exists rotary load and propulsive force by Artificial Control in drilling process, causes the lower problem of drilling efficiency.
The utility model content
The utility model purpose be for overcome mining-drilling machine because of rotary load and propulsive force by Artificial Control, cause the lower problem of drilling efficiency.
The utility model solves the problems of the technologies described above the technical scheme of being taked:
Motor load and propulsive force self-adaptive hydraulic rig, comprise pumping plant, operating desk, support frame, frame, drilling tool, unit head, hydraulic system, it is characterized in that: hydraulic system comprises high-pressure oil pump group, high-pressure oil pipe, propelling oil cylinder, the oil inlet pipe of high-pressure oil pipe is connected with pumping plant with oil return pipe, the working tubing of high-pressure oil pipe respectively with unit head on hydraulic motor be connected with propelling oil cylinder on the frame; Enter the pressure oil P2 that advances oil cylinder 7 and advance between the oil cylinder control reducing valve 9 far away is set; Control reducing valve 9 far away has a load-sensing body, is connected with the load-sensing body from the pressure oil P1 of hydraulic motor.
The load-sensing body comprises the spring between piston rod, plunger shaft rear end and the piston rod in the plunger shaft, plunger shaft.
The beneficial effects of the utility model show:
Owing to adopt the hydraulic system that the utility model proposes, make rig have adaptive ability, guarantee rig in drilling process, because the variation of nature of ground when the rig load increases, automatically reduces propulsive force and fltting speed, thereby reduce the load of rig; Because the variation of nature of ground when the rig load reduces, can increase propulsive force automatically, improves fltting speed.Prevented that rig load and propulsive force from by Artificial Control, can not adapt to the variation of nature of ground, caused the low problem of drilling efficiency.

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.
As shown in Figure 2 in the hydraulic system, enter between the pressure oil P2 that advances oil cylinder 7 and the propelling oil cylinder control reducing valve 9 far away is set; Control reducing valve 9 far away has a load-sensing body, is connected with the load-sensing body from the pressure oil P1 of hydraulic motor.The load-sensing body comprises the spring between piston rod, plunger shaft rear end and the piston rod in the plunger shaft, plunger shaft.Enter the pressure oil P2 that advances oil cylinder 7 and advance between the oil cylinder and also be provided with one way valve 8.
When the rig operate as normal, in the hydraulic system as shown in Figure 2, during the rig operate as normal, when the drill motor load increases, pressure oil P1 pressure from hydraulic motor raises, pressure oil enters load-sensing body 9, and load-sensing body rear end spring is compressed, and moves behind the piston rod, the reducing valve outlet pressure is reduced, pressure oil P2 enters the plunger shaft that advances oil cylinder 7 behind reducing valve pressure automatically reduces, thereby reduces propulsive force, and the drill motor load is reduced; Motor load reduces, pressure oil P1 pressure from hydraulic motor reduces, pressure oil enters load-sensing body 9, load-sensing body piston rod moves forward under the effect of rear end spring force, the reducing valve outlet pressure is increased, and pressure oil P 2 enters the plunger shaft that advances oil cylinder 7 behind reducing valve pressure increases automatically, thereby increases propulsive force, the drill motor load is increased, improve fltting speed.Realize the function of rig adaptive ability.
