Description
Technical Field
The utility model relates to the technical field of roadway mechanical equipment, in particular to a split type sliding mechanism of an airborne drilling machine.
Background
The stability of the forming tunnel is closely related to the transportation of subsequent equipment and materials, the working environment of operators and the transportation of mineral aggregate out of the well. The stress state of the original rock is destroyed in the process of tunnel excavation, the stress of surrounding rock of the tunnel is redistributed, and the surrounding rock moves to the tunnel space; when the stress reaches the strength of the surrounding rock, the surrounding rock is damaged, and the tunnel is propped up, and the side is sliced, etc. along with the damage. Therefore, along with the continuous increase of the depth and the intensity of coal mining, the method has the advantages of reducing the stress of surrounding rock, transferring the high stress of the surrounding rock, homogenizing the stress of the surrounding rock, avoiding the excessive concentrated stress, and ensuring the stability and the safety of a roadway.
At present, most mines use a method of organically combining supporting, reinforcing and pressure relief, and cooperatively operate to control surrounding rock deformation. Based on the method, a batch of equipment with advanced drilling and advanced support, such as an advanced drilling machine, is designed in the coal mine equipment industry, and the equipment is widely applied at home and abroad, but due to the limitation of the swing angle of a drill bit, the roadway is difficult to drill in all directions, the pressure of the surrounding rock of the roadway cannot be effectively relieved, and the stability problem of the surrounding rock of the roadway still cannot be solved.
The existing airborne drilling machine is generally arranged above a large cutting arm of the tunneling and anchoring complete equipment or is arranged at the front part or the tail part of an anchor rod drill carriage, and is more limited by the size of the whole machine and the roadway space, and has lower adaptability to small roadway operation. The machine-mounted drilling machine is provided with a sliding mechanism to drive the drilling tool to move between roadway sides, so that the drilling pressure relief requirement is met. The existing sliding mechanism comprises a single sliding oil cylinder driving mode and a double sliding oil cylinder driving mode, the sliding range of the sliding mechanism is limited by the single sliding oil cylinder driving mode, and when a small roadway is operated, the condition that a drilling tool interferes with the roadway side part before rotating to a pressure relief point easily occurs; if the double-slippage oil cylinder is adopted to correspondingly drive two drilling tools, the occupied space of the airborne drilling machine is overlarge, the weight is overlarge, the flexibility of the drilling tools is insufficient when the drilling tools move, and the adaptability to small-sized roadway operation is low.

Referring to fig. 1, the utility model provides a split type sliding mechanism of an airborne drilling machine, which comprises a sliding rail 1, a main sliding block 2, an auxiliary sliding block 3, a first driver 4 and a second driver 5; the main sliding block 2 and the auxiliary sliding block 3 are both in sliding connection with the sliding rail 1; one end of the first driver 4 is arranged on the sliding rail 1, and the other end of the first driver is arranged on the auxiliary sliding block 3 so as to drive the auxiliary sliding block 3 and the main sliding block 2 to synchronously slide along the sliding rail 1, and at the moment, the second driver 5 acts as a connecting rod; one end of the second driver 5 is arranged on the auxiliary sliding block 3, and the other end of the second driver is arranged on the main sliding block 2 to drive the main sliding block 2 to slide relative to the auxiliary sliding block 3, and the first driver 4 acts as a connecting rod at the moment; the driving directions of the first driver 4 and the second driver 5 are each arranged in parallel with the sliding direction of the main slider 2. The first driver 4 and the second driver 5 may be hydraulic cylinders, air cylinders or electric push rods, and in this embodiment, dual-cylinder driving is adopted.
The first driver 4 and the second driver 5 are connected with the auxiliary sliding block 3, so that the main sliding block 2 can be synchronously driven to slide when the first driver 4 stretches and contracts, and the drilling tool can move towards one side wall part of a roadway; and the second driver 5 can independently drive the main sliding block 2 to move towards the other side wall part of the roadway, so that the drilling pressure relief of the roadway wall part, namely the left wall part and the right wall part of the roadway, is finally realized under the single drilling tool working condition. When the split type sliding mechanism adopts a single drilling tool, the existing fixed oil cylinder (the second driver 5) is changed into a movable oil cylinder, so that the sliding range of the drilling tool is increased, and the situation that the drilling tool interferes with the roadway side part when rotating in the horizontal plane is effectively avoided.
The driving directions of the first driver 4 and the second driver 5 are parallel to the sliding direction of the main sliding block 2, so that the telescopic lengths of the first driver 4 and the second driver 5 are correspondingly equal to the moving distances of the main sliding block 2 and the auxiliary sliding block 3, and the moving efficiency of the main sliding block 2 and the auxiliary sliding block 3 on the sliding rail 1 is effectively improved. Simultaneously parallel arrangement makes occupation space of first driver 4 and second driver 5 less, and just only need set up the single drilling tool and can realize the brill of tunnel group portion for the whole occupation space of split sliding mechanism is less, weight is lighter, thereby has improved the drilling tool and has beaten the flexibility of in-process, and is higher to the adaptability of small-size tunnel brill operation.
The main sliding block 2 is connected with a mounting platform 21, a turntable, a swinging oil cylinder and a drilling tool can be mounted on the mounting platform 21, the swinging oil cylinder is used for driving the drilling tool to move in the height direction of the roadway side part, and the turntable is used for driving the swinging oil cylinder and the drilling tool to synchronously rotate so as to meet drilling requirements, and specific equipment structures on the mounting platform 21 can be set according to requirements.
Further, the top end of the sub slider 3 is provided with a double-lug seat linkage 31; the first driver 4 and the second driver 5 are respectively connected to two ear seats of the binaural coupling 31. In this embodiment, the first driver 4 and the second driver 5 are coaxially disposed at the connection end of the double-lug seat linkage member 31, the axial direction is perpendicular to the length direction of the sliding rail 1, and the movement stroke of the main sliding block 2 can be correspondingly calculated by monitoring the expansion stroke of the first driver 4, so that the expansion precision of the second driver 5 is improved, and the requirements on the center distance of double-cylinder installation and the expansion stroke of the cylinder are reduced. In addition, the double-lug seat linkage piece 31 is arranged at the top end of the auxiliary sliding block 3, so that the occupied space of the double oil cylinders is optimized.
As shown in fig. 2, in an embodiment, the binaural coupling 31 includes a first ear socket 311 and a second ear socket 312; the first lug seat 311 is welded to the side end of the auxiliary sliding block 3, and the second lug seat 312 is welded to the top end of the auxiliary sliding block 3; the first ear mount 311 is connected to the first driver 4, and the second ear mount 312 is connected to the second driver 5. In this embodiment, the through holes of the first ear seat 311 and the second ear seat 312 are coaxially arranged, and the size of the auxiliary slide block 3 along the sliding direction is matched with the size of the first ear seat 311 and the second ear seat 312, so that the size of the auxiliary slide block 3 is small enough, the influence on the moving stroke of the main slide block 2 is reduced, that is, the moving stroke of the drilling tool towards one side of the auxiliary slide block 3 is increased.
In another embodiment, the binaural coupling 31 comprises a first ear socket 311, a second ear socket 312 and a connecting plate; the first ear seat 311 and the second ear seat 312 are welded on a connecting plate, and the connecting plate is arranged at the top end of the auxiliary sliding block 3. The connecting plate and the auxiliary sliding block 3 can be connected through bolts, so that the connecting plate can be detached from the auxiliary sliding block 3, and the double-lug-seat linkage 31 is easy to maintain and replace.
Further, the sliding rail 1 is a T-shaped sliding rail; the main sliding block 2 and the auxiliary sliding block 3 are concave sliding blocks, and the free ends are provided with inverted buckles. In this embodiment, the first ear seat 311 is welded to the back-off; and the main sliding block 2 and the auxiliary sliding block 3 are arranged at the side of the sliding rail 1, so that the drilling tool can swing by a larger angle when swinging towards the bottom of a roadway, and the drilling range is enlarged. Compared with the traditional screw rod transmission structure (or belt transmission structure), the T-shaped sliding rail has stronger transmission stability, because the drilling tool needs to swing in the height direction of the roadway side, the sliding rail 1 needs to be provided with a side position, and one side of the sliding rail 1, which is far away from the main sliding block 2, is fixedly connected with other parts of the tunneling and anchoring complete equipment, so that the main sliding block 2 and the auxiliary sliding block 3 cannot extend to one side of the sliding rail 1, which is far away from the main sliding block 2, otherwise, interference can occur with other parts of the tunneling and anchoring complete equipment, and if the side position is provided with the traditional screw rod transmission structure, the weight of equipment such as a turntable, a swinging oil cylinder, the drilling tool and the like can be applied to the screw rod, the stress is unreasonable, and the service life of the screw rod is seriously influenced. Through setting up slide rail 1 into T type slide rail to carry out spacingly through back-off to main slider 2 and vice slider 3, the weight of equipment such as drilling tool can be conducted to slide rail 1, finally conducts to the fuselage of tunneling anchor complete sets, and the atress is more reasonable, thereby can prolong the life of equipment.
Referring to fig. 3, the split sliding mechanism further comprises a first backboard 6, a second backboard 7, an adapter board 8 and a third ear seat 9; the first back plate 6 and the second back plate 7 are arranged along the sliding direction of the main slider 2; the adapter plate 8 is detachably connected with the first backboard 6, and the third ear seat 9 is welded to the top end of the adapter plate 8. Specifically, the first backboard 6 and the second backboard 7 are fixedly connected with rigid pieces on the tunneling and anchoring complete equipment; the adapter plate 8 is detachably connected with the first backboard 6 through bolts, so that the third ear seat 9 can be maintained and replaced conveniently. In this embodiment, ear seats are disposed at two ends of the first driver 4 and the second driver 5, so that hinge structures are formed between the first driver 4 and the second driver 5 and corresponding ear seats respectively, and vibration resistance of the device can be improved to a certain extent, thereby improving service life of the device.
In addition, the split sliding mechanism further comprises a plurality of displacement sensors; displacement sensors are mounted on both the first driver 4 and the second driver 5. The displacement sensor can monitor the telescopic distance of the first driver 4 and the second driver 5 in real time, and the moving precision of the drilling tool on the sliding rail 1 is improved. Of course, the moving distance of the main slider 2 and the sub slider 3 may be monitored by other sensors.
In the principle of the present utility model described by taking the orientation shown in fig. 1 as an example, when the main slider 2 needs to move to the left (right side), the first driver 4 is extended, the sub-slider 3 moves to the left, and at this time, the second driver 5 does not operate, which corresponds to a link, and the main slider 2 can be driven to move to the left, so that the movement of the drilling tool to the left is finally realized. When the main sliding block 2 needs to move to the right side (left side part), the first driver 4 firstly resets, the rotary table drives the drilling tool to rotate from the left side to the right side, and the second driver 5 stretches again; at this time, the first driver 4 does not work, and the auxiliary slide 3 can be regarded as a fixing plate, so that one end of the second driver 5 is fixed, and the second driver 5 can further push the main slide 2 (i.e. the drilling tool) to move.
The split sliding mechanism is ingenious in a 'one-still-one-moving' matched driving mode, and when the first driver 4 works, the second driver 5 is stationary; when the second driver 5 works, the first driver 4 is static; the static party acts as the effect of connecting rod, carries out spacingly to the party of work to make the driver of work can promote the drilling tool to remove towards tunnel group portion. In addition, by arranging the axes of the first driver 4 and the second driver 5 in parallel, and simultaneously connecting both with the double-lug seat linkage member 31, the first driver 4 and the second driver 5 are partially overlapped in the horizontal direction perpendicular to the axis of the first driver 4, the occupied space of the first driver 4 and the second driver 5 is greatly reduced, and the adaptability of the split sliding mechanism to small roadway operation is improved.
It should be understood that the above description of the specific embodiments of the present utility model is only for illustrating the technical route and features of the present utility model, and is for enabling those skilled in the art to understand the present utility model and implement it accordingly, but the present utility model is not limited to the above-described specific embodiments. All changes or modifications that come within the scope of the appended claims are intended to be embraced therein.
