Belonging to the technical field of rock roadway fully mechanized mining machinery and drill wagons.
Background
At present, faults are important factors influencing the pushing progress of fully mechanized mining faces in coal mine production, and particularly mining areas with complex geological conditions and more faults. Under the condition that the whole working face of a liberation layer mined by gas extraction is rock, the rapid drilling and vibration and loosening of the cannon are carried out, and the auxiliary coal mining machine is used for cutting the rock to be the most effective means of the overly hard rock (f=7-10), so that higher requirements are put forward on the hard rock drilling equipment of the fully-mechanized coal mining working face.
Drilling operation of a fully-mechanized mining face under a coal mine is carried out in a traditional mode by manually holding a pneumatic rock drilling machine for drilling a blasthole. In the drilling process, workers need to push and hold the drilling machine by two hands, repeated carrying drilling machine equipment walks on the scraper conveyor, the labor intensity of the workers is extremely high, potential safety hazards exist, and the pushing height is limited; although the operation can be performed by lengthening the drill rod, the swing amount of the drill rod is increased, so that the inaccuracy of the drilling position is caused, the size of loose coal and rock is different, the transportation of the coal and rock is influenced, the operation efficiency is reduced, and the safety coefficient is also reduced; under the normal condition, the drilling speed is 8-10min when the deep hole with the average length of 2m is used, the operation efficiency is low, and the gas consumption (energy) of the drilling machine is large; the drilling machine has the advantages that two persons are required to operate and implement drilling simultaneously, the noise of the drilling machine is more than 130dB, the noise and dust are large, the physical and psychological health of workers is seriously damaged, and the pneumatic rock drill can not meet the requirement of drilling holes on the fully mechanized mining face through the secondary hard stones.
Aiming at the defects existing in the drilling operation process of the underground working face of the coal mine, a mechanized drilling machine device which replaces the traditional operation mode is available, such as a movable lifting hydraulic drilling machine with a telescopic platform, which is disclosed by the technical scheme, the movable lifting hydraulic drilling machine comprises a frame, the hydraulic drilling machine arranged on the frame and a crawler belt for driving the frame to walk, the hydraulic drilling machine is rotatably arranged on the frame through a rotary chassis, multi-angle drilling can be realized by the hydraulic drilling machine through the rotation of the rotary disk, lifting frames which are parallel to the frame and are used for adjusting the operation height of the hydraulic drilling machine are respectively arranged on two sides of the frame along the walking direction, guide cylinders which are perpendicular to the lifting frames are attached to the bottom of the frame, the lifting frames are slidably inserted into the guide cylinders through connecting columns on the side walls of the lifting frames, the connecting columns are perpendicular to the lifting frames and are of an integrated structure with the lifting frames, telescopic oil cylinders for driving the connecting columns to slide in the guide cylinders are arranged in the guide cylinders, and the telescopic cylinders of the hydraulic columns can push or pull the connecting columns in the guide cylinders to extend or retract on the two sides of the frame. The device can realize the automatic movement function along the fully mechanized coal mining operation face tunnel in the operation process, but the mobile platform walks on the tunnel bottom plate based on the crawler belt, so that the device is complex in operation, troublesome in assembly, huge in overall dimension, limited by the structure, can only implement punching operation at a fixed point, can not realize any hole site and angle use of a drilling machine in the whole fully mechanized coal mining operation face, and can not guarantee the uniformity of loose coal and rock. In addition, the lifting hydraulic drilling machine mechanism adopts a combination mode of a hydraulic oil cylinder, a swinging arm rod and a force arm rod to realize up-and-down lifting, and the stability of lifting operation is easily affected.
For this purpose, the applicant's main pipe unit has designed a "suspension rail rock drill" with bulletin number CN204609762U, which has the technical points: the rock drilling device adopts a connecting structure that a perpendicular shaft rotation mechanism is supported by a rock drilling device control arm provided with a vertical adjusting hydraulic cylinder, a lifting hydraulic cylinder and a horizontal adjusting hydraulic cylinder, and moves along a walking track at the top of a roadway through a driven walking wheel and a driving wheel at the upper part of the machine body, and a hydraulic pump station suspended on the walking track by the driven walking wheel is connected at the rear part of the machine body. The control arm of the rock drilling device consists of a long lug plate, a telescopic arm with a front connecting seat, a control arm telescopic hydraulic cylinder, a control arm telescopic sleeve with a rear connecting seat and the like, so that the rock drilling device can be lifted to a required operation position only by driving the orthogonal shaft rotary mechanism to rotate around the hinge shaft at the front end of the telescopic arm through the telescopic of the vertical adjustment hydraulic cylinder; the lifting hydraulic cylinder of the control arm of the rock drilling device is used for stretching to drive the control arm of the rock drilling device to rotate around the hinge shaft of the connector, and the operation position of the rock drilling device is adjusted to vertically lift. Although the device has compact structure and small occupied space, and moves stably, safely and reliably along the walking track at the top of the roadway, the device is found to have some problems to be overcome in practical application. For example, the control arm of the rock drilling device is of a telescopic cantilever single-support structure, the stress is not easy to balance, the vertical lifting and positioning operation is troublesome during the operation of the rock drilling device, and the stability is difficult to maintain. The quality of drilling blasting operation can be affected, and the production efficiency of the fully-mechanized coal mining face is reduced. The moving track of the drilling machine moves along the walking track at the top of the roadway and is used for the blasting hole drilling operation of the fully-mechanized coal mining operation surface blasting roadway. Because the friction wheels are mainly used for limiting the movement direction of the equipment driven by friction force in the track, the equipment cannot be disassembled at will on the track, so that the equipment cannot be assembled and disassembled and moved at any time according to actual needs, the fully-mechanized mining working face drilling machine cannot adapt to the change of the angle of the scraper conveyor, and the advancing direction of the working face cannot be changed along with the change of the angle of the fully-mechanized mining equipment.
The utility model discloses a "multi-angle coal rock rig" of publication No. CN102182397A, the rig of describing mainly comprises horizontal guide rail, lift guide rail, base, drilling rod and motor, and horizontal guide rail is connected with the lift guide rail through the sliding sleeve that sets up on the lift guide rail, is equipped with two oblique flexible support arms of being connected with horizontal guide rail on the sliding sleeve symmetry, is equipped with the perpendicular lower flexible support arm that descends at horizontal guide rail both ends, and the drilling rod drive seat sets up in the track inslot of horizontal guide rail, still is equipped with the propulsion hydro-cylinder in the track inslot of horizontal guide rail. The drilling machine is mainly used in mine roadways, and can not move randomly on a track, so that the moving direction is limited, the horizontal guide rail of the drilling machine can not be tightly matched with a coal (rock) wall, and the combined application is restricted.
In developed countries, fully mechanized mining face drilling operations have already achieved manual to fully mechanized drilling transitions; in China, although hydraulic drills are rapidly developed and various hydraulic drills are developed, the conventional hydraulic drills have the defects of inflexible drilling arms, small operation range, large size of the drills and auxiliary mechanisms, low automation degree, low operation efficiency and the like, and the drilling quality, precision and efficiency are improved by further improving the drilling device.
Therefore, in order to meet the requirement of drilling operation of the fully-mechanized mining face, it is necessary to develop equipment capable of meeting the combined recovery requirement of the fully-mechanized mining face on the machine and the gun. The combined stoping, namely the combined mining mode of the machine gun, generally refers to a coal mine comprehensive mechanized coal mining working face, and is formed by matching three machines of a coal mining machine, a scraper conveyor and a hydraulic support. When the rock faults or the rock working surface are crossed in the production process of the coal mine, particularly when the rock hardness exceeds the common coefficient 6, under the condition that the coal mining machine cannot cut through the rock, the rock wall drilling and drilling construction is necessary to be carried out in the working surface, and then the rock is blasted and loosened, namely the blasting and mining is matched with the coal mining machine and other operations.
