Description

Machine-mounted drilling machine and tunneling and anchoring complete equipment

Technical Field

The invention relates to the technical field of roadway mechanical equipment, in particular to an onboard drilling machine and tunneling and anchoring complete equipment.

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. And only one swing oil cylinder and one sliding oil cylinder are configured, so that the up-down drilling range of the airborne drilling machine is smaller, and the roadway wall surface beyond the drilling range is difficult to effectively drill. The design of the sliding oil cylinder limits the sliding range of the machine-mounted drilling machine, and when the small-sized roadway is operated, the drill rod is interfered with the roadway side part before rotating to the pressure relief point; if the two slipping cylinders are adopted to correspondingly drive the two drill rods, the occupied space of the airborne drilling machine is overlarge, the weight is overlarge, the swing flexibility is insufficient, the requirements on the installation distance and the telescopic travel are higher when the two slipping cylinders are installed, and the adaptability to small-sized roadway operation is lower.

Referring to fig. 1, the invention provides an on-board drilling machine, which comprises a rotary speed reducer 1, a double-drive pitching mechanism 2, a drilling mechanism 3 and a split sliding mechanism 4. The double-drive pitching mechanism 2 is rotationally connected with the rotary speed reducer 1; the drilling mechanism 3 is arranged on the double-drive pitching mechanism 2; the double-drive pitching mechanism 2 can drive the drilling mechanism 3 to swing in the height direction of the roadway side part; the split sliding mechanism 4 is connected with the rotary speed reducer 1 through a supporting seat and can drive the rotary speed reducer 1 to move towards the roadway side part. The roadway comprises a top and sides, wherein the top is the top of the roadway, the sides are the two side wall surfaces of the roadway, and the sides refer to the two side wall surfaces of the roadway, namely a left side part and a right side part.

The double-drive pitching mechanism 2 is rotationally connected with the rotary speed reducer 1, and the drilling mechanism 3 is arranged on the double-drive pitching mechanism 2. The double-drive pitching mechanism 2 is two driving mechanisms, and the drilling mechanism 3 is driven by the two driving mechanisms, so that the drilling mechanism 3 can swing twice, and angles of the two swinging are overlapped, thereby increasing the swinging range of the drilling mechanism 3 in the height direction of the roadway side part; the double-drive pitching mechanism 2 and the rotary speed reducer 1 are driven in a matched mode, and the drilling range of the drilling mechanism 3 is greatly increased.

The split sliding mechanism 4 is connected with the rotary speed reducer 1 and can drive the rotary speed reducer 1 to move towards the roadway side part. The traditional sliding mechanism is a separated double-oil-cylinder driving structure, and adopts a double-drilling mechanism to drill the roadway side part, namely, one oil cylinder independently drives one drilling mechanism. The split type sliding mechanism 4 is characterized in that two driving structures are arranged on the sliding mechanism, and one drilling mechanism 3 is driven to move between the roadway sides through the two driving structures. Compared with the traditional sliding mechanism, the split sliding mechanism 4 can enable the drilling mechanism 3 to occupy the minimum space to meet the pressure relief requirement of the maximum roadway width, the requirement on the installation distance and the travel of two driving structures is reduced, the flexibility is higher, and the adaptability to the roadway with smaller upper space is stronger.

The traditional double-drilling mechanism is changed into the single-drilling mechanism, so that the occupied space of the drilling mechanism 3 is reduced, the equipment cost is reduced, the swinging of the drilling mechanism 3 is more flexible, and the drilling mechanism is more suitable for the roadway drilling requirement with narrower upper space.

As shown in fig. 2, the dual drive pitch mechanism 2 includes a hinged bracket 21, a swing arm 26, a pair of primary telescopic drives 24, and a pair of secondary telescopic drives 25; the hinged support 21 is arranged on the rotary speed reducer 1, and the rotary speed reducer 1 can drive the hinged support 21 to rotate in a horizontal plane; one end of the swing arm 26 is hinged with the hinged support 21, and the other end is hinged with the drilling mechanism 3; one end of the secondary telescopic driver 25 is hinged with the drilling mechanism 3, and the other end is hinged with the swing arm 26; the paired two-stage telescopic drivers 25 are arranged in mirror image with the swing arm 26 as the center; one end of the primary telescopic driver 24 is hinged with the hinged support 21, and the other end is hinged with the swing arm 26; the pair of primary telescopic drives 24 are mirror-image centered on the swing arm 26. Specifically, the primary telescopic driver 24 and the secondary telescopic driver 25 may be telescopic devices such as a hydraulic cylinder, an air cylinder or an electric push rod, and in this embodiment, an oil cylinder is selected; the paired primary telescopic drivers 24 and the paired secondary telescopic drivers 25 are correspondingly arranged on two sides of the drilling mechanism 3, so that the stability of the transmission of the airborne drilling machine is enhanced while the swinging angle of the drilling mechanism 3 is increased.

Taking the direction shown in fig. 2 as an example, the hinge point of the mounting bracket 32 and the swing arm 26 is the rotation point 23 of the drilling mechanism 3, and when the primary telescopic actuator 24 stretches and contracts, the drilling mechanism 3 can swing around the hinge point 22 of the hinge bracket 21 and the swing arm 26 as a center point, which is one swing; when the secondary expansion/contraction actuator 25 expands and contracts, the drilling mechanism 3 can oscillate again around the rotation point 23 as a center point, which is a secondary oscillation. The maximum angle at which the drilling mechanism 3 can oscillate, that is, the sum of the maximum oscillation angles of the primary oscillation and the secondary oscillation, is set corresponding to the maximum extension of the primary expansion actuator 24 and the secondary expansion actuator 25 by controlling the primary expansion actuator. In the operation process of the secondary telescopic driver 25, the primary telescopic driver 24 can operate simultaneously, so that the drilling mechanism 3 is easier to swing, the swing speed is faster, and the operation efficiency is higher; the primary telescopic drive 24 can also be out of operation to enhance the stability of transmission and make construction safer. Similarly, the contraction process of the primary expansion actuator 24 and the secondary expansion actuator 25 can be analogous to the expansion process, and will not be described again.

Further, the swing arm 26 is provided with a first ear plate and a second ear plate; the first ear plate is arranged at the bottom end of the swing arm 26, and the primary telescopic driver 24 is hinged with the first ear plate; the second ear plate is arranged at the side end of the swing arm 26, and the secondary telescopic driver 25 is hinged with the second ear plate. Specifically, when the primary telescopic driver 24 telescopically swings, the swinging arm 26 can drive the secondary telescopic driver 25 and the drilling mechanism 3 to synchronously swing around the hinge point 22; when the secondary telescopic driver 25 stretches and swings, the primary telescopic driver 24 does not move, at this time, the primary telescopic driver 24 plays a role of a supporting rod, and the secondary telescopic driver 25 can further drive the drilling mechanism 3 to swing around the rotating point 23 by taking the swinging arm 26 as a supporting point. The swing arm 26 acts as a hinge in the swing adjustment of the drilling mechanism 3, and plays a role of "up and down.

Secondly, the split sliding mechanism 4 comprises a first sliding driver 41, a second sliding driver 42, a main sliding block 43, an auxiliary sliding block 44, a sliding rail 45 and a supporting seat; the main sliding block 43 is connected with the rotary speed reducer 1 through a supporting seat, namely one end of the supporting seat is connected with the main sliding block 43, and the other end of the supporting seat is connected with the rotary speed reducer 1; the main sliding block 43 and the auxiliary sliding block 44 are both in sliding connection with the sliding rail 45; one end of the first sliding driver 41 is arranged on a sliding rail 45, and the other end is connected with a secondary sliding block 44; one end of the second slide driver 42 is connected to the main slider 43, and the other end is connected to the sub slider 44. The sliding rail 45 is fixed on other components of the tunneling and anchoring complete equipment, and the sliding rail 45 can be regarded as a fixing piece. The first sliding driver 41 and the second sliding driver 42 may be telescopic devices such as a hydraulic cylinder, an air cylinder or an electric push rod, and in this embodiment, an oil cylinder is selected, so that the oil cylinder is driven more stably for large-scale devices.

Taking the direction shown in fig. 2 as an example, when the drilling mechanism 3 needs to move to the left (right side), the first sliding driver 41 is extended, the auxiliary slider 44 moves to the left, and at this time, the second sliding driver 42 does not work, which corresponds to a link, and the main slider 43 can be driven to move to the left, so that the drilling mechanism 3 can be finally moved to the left. When the drilling mechanism 3 needs to move to the right side (left side part), the first sliding driver 41 is reset firstly, the rotary speed reducer 1 drives the drilling mechanism 3 to rotate from the left side to the right side, and the second sliding driver 42 is extended again; at this time, the first sliding driver 41 is not operated, and the auxiliary slider 44 can be regarded as a fixing plate, so that one end of the second sliding driver 42 is fixed, and the second sliding driver 42 can further push the main slider 43 (i.e. the drilling mechanism 3) to move. The split type sliding mechanism 4 is ingenious in a 'one-static one-moving' matched driving mode, and when the first sliding driver 41 works, the second sliding driver 42 is static; the second slip drive 42 is in operation and the first slip drive 41 is stationary. The static one acts as a connecting rod to limit one working one, so that the working sliding driver can push the drilling mechanism 3 to move towards the roadway side.

Based on this, arranging the first and second slider drivers 41 and 42 side by side can be understood that there is a partial overlap of the first and second slider drivers 41 and 42 in the sliding direction of the slide rail 45, thereby saving the occupied space of the first and second slider drivers 41 and 42. The traditional double-cylinder driving mode is that two cylinders are arranged on the left side and the right side of the sliding rail 45, one cylinder independently drives one drilling mechanism 3, that is, the two cylinders have no overlapped part in the sliding direction of the sliding rail 45, and the requirements on the installation distance and the travel of the two cylinders are higher in the arrangement process, so that the expansion and contraction amounts of the two cylinders to the left side wall part or the right side wall part are consistent, the cylinders are troublesome in installation, the split type sliding mechanism 4 reduces the requirements on the installation distance and the travel, meets the depth requirement of drilling, and is more convenient to install.

In addition, the slide rail 45 is a T-shaped slide rail; the main slider 43 and the auxiliary slider 44 are concave sliders, and the free ends are provided with back-ups. In order to avoid interference between the drilling mechanism 3 and the sliding rail 45, the drilling mechanism 3, the rotary speed reducer 1 and the dual-drive pitching mechanism 2 are arranged on the side of the sliding rail 45, so that the drilling mechanism 3 can swing by a larger angle when swinging downwards. Compared with the traditional screw rod transmission structure (or belt transmission structure), the T-shaped sliding rail has stronger transmission stability, because the drilling mechanism 3 is required to swing in the height direction of the roadway side, the sliding rail 45 is required to be arranged at a side position, and one side of the sliding rail 45 away from the rotary speed reducer 1 is fixedly connected with other parts of the tunneling and anchoring complete equipment, so that the main sliding block 43 and the auxiliary sliding block 44 cannot extend to one side of the sliding rail 45 away from the rotary speed reducer 1, otherwise, interference can occur with other parts of the tunneling and anchoring complete equipment, and if the side position is arranged in the traditional screw rod transmission structure, the weight of the equipment such as the rotary speed reducer 1, the double-drive pitching mechanism 2 and the drilling mechanism 3 can be applied on the screw rod, the stress is unreasonable, and the service life of the screw rod is seriously influenced. According to the invention, the slide rail 45 is set as the T-shaped slide rail, the main slide block 43 and the auxiliary slide block 44 are limited by the back-off, the weight of equipment such as the drilling mechanism 3 can be transmitted to the slide rail 45 and finally transmitted to the machine body of the tunneling and anchoring complete equipment, and the stress is more reasonable, so that the service life of the equipment can be prolonged.

Further, the sub slider 44 is provided with a first ear seat and a second ear seat; the first ear mount is connected with a first sliding driver 41; the second ear mount is connected to a second slide driver 42. The first ear seat and the second ear seat are arranged on the auxiliary sliding block 44 in parallel, so that the first sliding driver 41 and the second sliding driver 42 can be arranged in parallel, the occupied space of the first sliding driver 41 and the second sliding driver 42 is reduced, and only one drilling mechanism 3 is required to be arranged, so that the onboard drill can be suitable for a roadway with smaller upper space.

Next, the drilling mechanism 3 includes a rotary driver 31 and a mounting bracket 32; the mounting bracket 32 is hinged to the swing arm 26, and the swing actuator 31 is mounted on the mounting bracket 32. In this embodiment, the swing actuator 31 is a hydraulic motor. According to the invention, the drilling mechanism 3 is driven to swing in the horizontal plane through the rotary speed reducer 1, and the drilling mechanism 3 is driven to swing in the height direction of the roadway side part through the double-drive pitching mechanism 2 for two times, so that a drill rod can be aligned to a pressure relief point of the roadway side part, the swing range is large, and the adaptability to different roadway heights is strong; the split type sliding mechanism 4 drives the drilling mechanism 3 to move between the roadway sides, the rotary driver 31 is matched for drilling, only one drilling mechanism 3 is needed, the bearing pressure of the rotary speed reducer 1 and the sliding rail 45 is reduced, the drilling mechanism 3 is more flexible in swinging, and the service life is longer.

In addition, the drilling mechanism 3 further comprises a clamping mechanism 33 mounted on the mounting bracket 32; the clamping mechanism 33 is rotatably connected to the rotary shaft of the rotary actuator 31. The clamping mechanism 33 further enhances the stability of the drill rod when the drilling mechanism 3 drills, and can further improve the drilling precision. The clamping mechanism 33 is used for matching the rotation of the drill rod and the splicing and the disassembly of two sections of drill rods, and the clamping mechanism 33 locks or unlocks the drill rod through the telescopic control slips of the clamp cylinders at the two ends, so that the purpose of disassembling the drill rod is achieved. For an on-board drilling machine, the clamping mechanism 33 can be produced in a customized manner based on the size and weight of the drill pipe and the splice limit of two sections of drill pipe.

In addition, the invention also provides a complete equipment for digging and anchoring, which comprises the airborne drilling machine. In this embodiment, dig anchor complete sets of equipment includes host computer and back supporting, and wherein the host computer can also be called dig anchor all-in-one, and the back supporting can be called the transfer unit, and the host computer front portion is provided with cutting device, and the machine carries the rig setting in the transfer unit front portion, and hopper and breaker are located machine carries the rig rear side, and the transfer unit can carry out the omnidirectional release of multi-angle to the top and the group in tunnel to reduce the country rock stress, guarantee the stability and the construction safety in tunnel.

The digging and anchoring complete equipment also comprises a pair of working tables 5, and the working tables 5 are connected with the on-board drilling machine through a hydraulic mechanism; pairs of work tables 5 are provided on both sides of the tunnel boring and anchoring complete equipment. The operation valve group (i.e. the workbench 5) of the existing airborne drilling machine is installed on an airborne large arm or matched equipment, and only one operation valve group is configured, so that the interchangeability and convenience of underground operation positions are not facilitated, and the equipment arrangement condition of various roadways is difficult to adapt. The hydraulic mechanism is arranged in the embodiment and is connected with the airborne drilling machine in a parallel connection mode, so that the workbench 5 on any side can control the airborne drilling machine, an operator can select a proper operation position according to the site condition, for example, when drilling on the left side, the operator operates the workbench 5 on the right side, the situation that the operator is accidentally injured in the operation process of the airborne drilling machine can be effectively avoided, and the construction safety and flexibility are improved. The hydraulic mechanism adopts the existing hydraulic control system, and the invention emphasizes the technical scheme that the hydraulic mechanism is applied to the paired working tables 5 in a parallel connection mode so as to increase the construction safety.
