Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mining exploration, in particular to a drilling machine for mineral engineering geological exploration. BACKGROUND

[0002] In the field of mineral engineering geological exploration, most traditional drilling machines are of integrated structure, and have large and heavy overall volume, which makes it difficult to pass through and operate flexibly in complex terrain and poor traffic conditions, such as narrow mountain paths, small roads in dense forests, and narrow streets in cities. If the vehicle cannot directly reach the area, the drilling work is often hindered, which seriously limits its application range. During transportation, the overall volume of the traditional drilling machine is large due to the non-dismountable overall structure, and the drilling frame cannot be folded, resulting in high difficulty and cost of transportation.

[0003] The drilling device and method for vehicle-mounted underground exploration shown in Chinese Patent No. CN119466573A include a mounting plate, four guide rails, a first hydraulic cylinder, a movable frame, and a drilling mechanism. The vehicle-mounted underground exploration drilling device in the present application is installed in the vehicle compartment through the mounting plate and guide rails, which facilitates the transportation of the drilling mechanism to the designated location by the vehicle, improving the convenience of transportation. Moreover, the drilling mechanism and the movable frame are detachably connected, so when the vehicle cannot reach the exploration site, the drilling mechanism and the movable frame can be separated, and then the drilling mechanism can be manually moved to the designated location for drilling operation, enhancing the flexibility of the device. The device shown in the above-mentioned patent can transport the drilling mechanism in a split manner, but the drilling mechanism is always in a vertical installation state, the drilling depth is limited, and it cannot adapt to the installation of long drill rods, and it cannot pass through some areas with height restrictions such as dense forests, etc. The overall stability of the above-mentioned device is poor, and it needs to be manually transported, which cannot adapt to long-distance complex road conditions. The movable frame body has insufficient support force from the ground during drilling, resulting in insufficient overall stability.

[0004] In addition, the traditional drilling machine also has deficiencies in work stability. In complex geological conditions such as soft soil layer and slope, the drilling machine is prone to shaking, displacement due to vibration, uneven ground or other external forces, which affects the accuracy and reliability of drilling work, and further leads to drilling accidents and errors, reducing the drilling quality.

This makes the drilling machine able to move to the target position for drilling by separating the frame in areas where vehicles are difficult to reach, greatly expanding the scope of application, and has the ability to flexibly pass through narrow mountain paths, dense jungle paths and other complex road conditions. At the same time, the smaller turning radius improves the maneuverability in limited space, thereby improving the work efficiency.

[0021] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-14 The drilling rig for mineral engineering geological exploration shown includes an exploration vehicle chassis 1 and a detachable frame 2 mounted on the chassis 1. The frame 2 has wheels 3 at its bottom, and the chassis 1 has limiting grooves 4 for the wheels 3 to travel on. The chassis 1 is connected to the frame 2 via a connecting mechanism 5. A drilling mechanism is mounted on the frame 2, including a drilling frame 6 composed of an upper frame 7 and a lower frame 8, and a lifting frame 9 mounted on the upper frame 7. A drilling rig device for drilling is mounted on the lifting frame 9. 10. The chassis 1 is provided with a clearance passage for the drilling rig 10 to work. The lower frame 8 is a hinged folding frame. The frame 2 is provided with a support frame 11. The upper frame 7 is fixed on the support frame 11. The drilling frame 6 is equipped with a locking device 12 to lock the drilling frame 6 in the folded or unfolded state. The two sides of the frame 2 are provided with extendable mounting frames 13. The mounting frames 13 are provided with a main insertion rod 14 that can be inserted into the soil layer. The main insertion rod 14 is also provided with a number of branch insertion rods 15 that are distributed in a ring and extend outward from the main insertion rod 14.

[0023] In the present application, the chassis 2 is provided with a detachable frame 2, and the drilling mechanism is arranged on the frame 2, so that the drilling machine can work efficiently in various complex environments. In some complex terrain, the vehicle cannot directly reach the area, the frame 2 can be separated, and the frame 2 can be moved to the target position for drilling through the walking wheel 3 itself, avoiding the work being blocked due to the vehicle cannot reach. The narrow, low and short shape characteristics make it easy to deal with poor road conditions, and it can flexibly pass through narrow mountain paths and small roads in dense forests during field exploration, greatly widening the application range of the drilling machine. The smaller turning radius further improves the maneuverability in limited space, facilitating the adjustment of the drilling position in complex terrain and improving the work efficiency. The frame 2 adopts a short wheelbase design, and the independent steering structure of the walking wheel 3 makes the turning radius smaller than that of the conventional drilling machine. When the frame 2 is installed on the chassis 1, the chassis 1 and the frame 2 are fixedly connected through the connecting mechanism 5 on the chassis 1, and the drilling mechanism can be used for drilling work on the frame 2 alone, or can be used for work on the chassis 1 in the connected state, and the connecting mechanism 5 will not be disconnected when working on the chassis 1.

[0024] The hinge folding frame design of the drilling frame 6 and the overall structure of the detachable frame 2 make the drilling machine more convenient to transport. When not in use, the drilling frame 6 can be folded to reduce the overall volume of the equipment, and the passability and stability of the frame 2 can be improved when moving alone.

[0025] The mounting frame 13 and the main insertion rod 14 arranged thereon can be retracted into the frame 2, and when locking is required, the mounting frame 13 is moved to the side of the frame 2, the main insertion rod 14 is rotated and inserted into the ground, and then the sub-insertion rod 15 is expanded outward to further improve the grip. The structure can form multiple locking connection points between the drilling machine and the ground, effectively prevent the drilling machine from shaking, shifting or being affected by other external forces during drilling, and ensure the accuracy and reliability of the drilling work. Especially in some complex geological conditions, such as soft soil layer, slope and the like, the stable support structure can ensure the normal operation of the drilling equipment, improve the drilling quality, and reduce the drilling accidents and errors caused by unstable equipment. The retraction of the mounting frame 13 can reduce the width of the frame 2 and increase the passability to adapt to more severe traffic environment. The extension of the mounting frame 13 can improve the stability of the ground fixation, and when connected with the chassis 1, the mounting frame 13 can be extended and locked from the direction of travel to improve the stability of the body connection and reduce the bumping during driving, avoiding causing damage to the equipment.

[0026] It is worth mentioning that the frame 2 shown in the present application has a power mechanism at the front end, which provides driving power for travel, avoids manual transfer, and improves the traffic capacity.

[0027] The connecting mechanism 5 comprises first connecting devices arranged on the base plate 1, and locking grooves 16 are arranged on the side walls of the frame 2. The first connecting devices comprise bidirectional screw rod sliding tables 17, first hinged rods 18 and locking blocks 19. The bidirectional screw rod sliding tables 17 are arranged in the same direction as the length direction of the base plate 1. The first hinged rods 18 are arranged on two sliding seats of the bidirectional screw rod sliding tables 17. The locking blocks 19 are arranged in the middle of the bidirectional screw rod sliding tables 17. One end of the first hinged rods 18 is hinged to the sliding seats, and the other end is hinged to the locking blocks 19. The locking blocks 19 can be inserted into the locking grooves 16. Rubber pads are filled outside the locking blocks 19.

[0028] When the drilling machine needs to connect the frame 2 and the base plate 1, first, the frame 2 is moved above the base plate 1, so that the locking grooves 16 on the frame 2 correspond to the positions of the locking blocks 19 of the first connecting devices on the base plate 1, and the subsequent locking operation is prepared.

[0029] When the frame 2 moves to the locking position of the base plate 1, the first connecting devices are started to lock and connect the frame 2 and the base plate 1. The bidirectional screw rod sliding tables 17 work to drive the two sliding seats to move towards each other. The first hinged rods 18 drive the locking blocks 19 to move horizontally towards the frame 2. The locking blocks 19 are inserted into the locking grooves 16 on the side walls of the frame 2, so as to realize the locking and connecting function of the frame 2 and the base plate 1. The rubber pads have a certain elasticity. When the locking blocks 19 are inserted into the locking grooves 16, the rubber pads can fill the gap between the locking blocks 19 and the locking grooves 16, increase the friction and sealing between the two, prevent the locking blocks 19 from loosening due to vibration and other reasons during the operation of the drilling machine, and ensure the stability of the connection between the frame 2 and the base plate 1.

[0030] The frame 2 is further provided with a telescopic mechanism in transmission connection with the mounting frame 13. The telescopic mechanism comprises first and second hydraulic rods 20 and 21, a horizontal telescopic frame 22, first and second hinged rods 24 and 23, and the first hydraulic rod 20 and the second hydraulic rod 21 are vertically arranged on the frame 2. The output end of the first hydraulic rod 20 is fixedly connected with the first lifting plate 23. One end of the horizontal telescopic frame 22 is fixedly connected with the first lifting plate 23, and the other end is fixedly connected with the mounting frame 13. The second hinged rod 24 is hinged at both ends to the output end of the second hydraulic rod 21 and the side wall of the mounting frame 13. The frame 2 is provided with a horizontal abutting plate 25 flush with the bottom of the mounting frame 13 in the retracted state.

[0031] When the frame 2 needs to be separated from the chassis 1 to move by itself, in order to reduce the width of the frame 2 and increase its passability, the mounting rack 13 needs to be retracted into the frame 2. The first hydraulic rod 20 drives the first lifting plate 23 to rise, and the horizontal telescopic rack 22 fixedly connected with the first lifting plate 23 drives the mounting rack 13 to rise synchronously, and the second hydraulic rod 21 retracts to drive the second articulated rod 24 to deflect. At this time, the horizontal telescopic rack 22 retracts, and the mounting rack 13 retracts into the frame 2. When the frame 2 is connected with the chassis 1 or the drilling mechanism is preparing to work, the mounting rack 13 needs to be extended out of the frame 2. The second hydraulic rod 21 extends out and drives the mounting rack 13 to extend outwards through the second articulated rod 24. After complete extension, the first hydraulic rod 20 and the second hydraulic rod 21 are synchronously driven, the second articulated rod 24 and the horizontal telescopic rack 22 are synchronously lowered, thereby stably lowering the mounting rack 13. After reaching the predetermined position, the second hydraulic rod 21 continues to retract, and a part of the top of the mounting rack 13 is attached to the horizontal abutting plate 25, so that the frame 2 and the mounting rack 13 play a supporting role in the vertical direction. The design of the telescopic mechanism enables the mounting rack 13 to be flexibly telescoped according to actual work requirements. When the frame 2 needs to move by itself in complex road conditions, the mounting rack 13 can be retracted into the frame 2, reducing the overall width of the frame 2, so that the frame 2 can smoothly pass through narrow passages or space-limited areas, greatly improving the mobility and passability of the drilling machine. When drilling, the mounting rack 13 extends out of the frame 2 and is connected to the ground through the main insertion rod 14 and the branch insertion rod 15, providing stable support for the drilling machine and ensuring smooth drilling work. This function of flexibly adjusting the state of the mounting rack 13 in different working scenarios enhances the adaptability of the drilling machine to various working environments and improves the practicality of the equipment.

[0032] The connecting mechanism 5 further comprises a second connecting device, which comprises a lateral abutting plate 26 hingedly arranged at the bottom of the chassis 1. The outer side wall of the lateral abutting plate 26 is attached to the side wall of the mounting rack 13 in the extended state and the attachment surface is the front end or the rear end of the chassis 1. A support rod 27 hingedly arranged between the lateral abutting plate 26 and the chassis 1 is further provided. The support rod 27 is provided with an abutting block 28 attached to the lateral abutting plate 26 at the top, and an adjusting telescopic member 29 is arranged in the middle of the support rod 27.

[0033] When the frame 2 is connected with the chassis 1 and the mounting frame 13 is extended, in order to further enhance the stability of the connection, the second connecting device needs to be started. At this time, the lateral abutting plate 26 is flipped over with the hinge point at the bottom of the chassis 1 as the axis until it is flipped to the vertical state and tightly abuts against the side wall of the extended mounting frame 13. After the lateral abutting plate 26 is flipped into place, the support rod 27 is lifted up through its hinge point with the chassis 1, so that the abutting block 28 at the top abuts against one side of the top end of the lateral abutting plate 26. Then, the adjusting telescopic part 29 starts to work, by adjusting its length, the support angle and intensity of the support rod 27 are changed, so as to accurately adjust the abutting support force of the lateral abutting plate 26, and ensure that the lateral abutting plate 26 can stably provide lateral support for the mounting frame 13.

[0034] The third hydraulic rod 30 is installed on the frame 2, the lower frame 8 is divided into two hinge folding frames which are hingedly connected with each other, the third hydraulic rod 30 is hingedly arranged at the front end of the frame 2, the output end of the third hydraulic rod 30 is in transmission connection with the hinge points of the two hinge folding frames, and the two hinge folding frames are provided with the first linear guide rail 31 on the side facing each other in the folded state. The second linear guide rail 32 is installed on the upper frame 7, the first linear guide rail 31 and the second linear guide rail 32 are combined to form a complete linear guide rail in the unfolded state of the drilling frame 6. The lifting frame 9 is vertically slidably connected with the drilling frame 6 through the linear guide rail. The top end of the upper frame 7 is provided with a multi-stage telescopic hydraulic cylinder 33, and the output end of the multi-stage telescopic hydraulic cylinder 33 is fixedly connected with the upper frame 7.

[0035] When it is necessary to unfold the drilling frame 6, the third hydraulic rod 30 pushes the two hinge folding frames to flip around the hinge points therebetween. The two hinge folding frames are gradually flipped from the folded state to the vertical state, and in this process, the upper frame 7 connected with the upper hinge folding frame is also synchronously lifted upward. When the two hinge folding frames are completely in the vertical state, the first linear guide rail 31 installed on the side facing each other of the two hinge folding frames is combined with the second linear guide rail 32 on the upper frame 7 to form a complete linear guide rail. At this time, the lifting frame 9 is slidably connected with the drilling frame 6 in the vertical direction through the linear guide rail. Then, the multi-stage telescopic hydraulic cylinder 33 at the top end of the upper frame 7 is started, the output end of the multi-stage telescopic hydraulic cylinder 33 is extended or retracted, and the lifting frame 9 is lifted along the linear guide rail to realize drilling at different depths. When the drilling work is completed or the drilling machine needs to be transported, the drilling frame 6 needs to be folded. At this time, the multi-stage telescopic hydraulic cylinder 33 moves the lifting frame 9 to a suitable position, and then the third hydraulic rod 30 reverses to pull the two hinge folding frames to flip around the hinge points to the folded state. With the pulling of the third hydraulic rod 30, the upper frame 7 gradually descends, the first linear guide rail 31 and the second linear guide rail 32 are separated, and finally the two hinge folding frames return to the folded state, reducing the occupied space of the drilling frame 6, facilitating transportation and storage.

[0036] The fourth hydraulic rod 34 is further arranged on the frame 2, and an output end of the fourth hydraulic rod 34 is hingedly connected to the top of the support frame 11; a lifting seat 51 capable of lifting is arranged on the frame, and the fourth hydraulic rod 34 and the support frame 11 are respectively hingedly connected to two ends of the lifting seat 51.

[0037] The fourth hydraulic rod 34 can realize the folding function of the support frame 11, and further drive the upper frame 7 connected thereto to be synchronously turned and folded, so as to further reduce the height, enhance the passability and driving stability. During the unfolding of the hingedly folded frame into the vertical state, the lifting seat 51 is lifted to drive the support frame 11 to be displaced, so that the support frame 11 is always kept in the vertical state.

[0038] The second lifting plate 35 capable of lifting is arranged in the mounting frame 13, the main insertion rod 14 is arranged below the second lifting plate 35, the second lifting plate 35 is provided with a rotation driver 36 for driving the main insertion rod 14 to rotate, the main insertion rod 14 is hollow, the pull rod 37 is coaxially arranged in the main insertion rod 14, the fifth hydraulic rod 38 is arranged on the second lifting plate 35, an output end of the fifth hydraulic rod 38 is fixedly connected to the pull rod 37, the pull rod 37 is in transmission connection with a plurality of branch insertion rods 15, and the main insertion rod 14 is provided with a plurality of guide limiting holes 39 for the branch insertion rods 15 to be inserted.

[0039] When it is needed to stably support the frame 2 on the ground, the rotation driver 36 drives the main insertion rod 14 to rotate, the second lifting plate 35 is lowered to drive the main insertion rod 14 arranged thereon to be lowered and inserted into the soil layer to be fixed, when the insertion is completed, the fifth hydraulic rod 38 on the second lifting plate 35 pulls the pull rod 37 to be upwardly displaced, so that the plurality of branch insertion rods 15 are expanded outwardly from the guide limiting holes 39, and in this way, the frame 2 is efficiently and stably supported on the ground. The main insertion rod 14 is inserted into the soil by rotating, can quickly and firmly fix the position of the frame 2, and provides a basis for the expansion of the branch insertion rods 15. The branch insertion rods 15 are expanded outwardly from the main insertion rod 14, greatly increase the contact area and the gripping force with the soil, so that the drilling machine can be kept stable under various geological conditions, effectively avoids the shaking and displacement caused by the uneven ground or external force, and ensures the smooth drilling operation.

[0040] The plurality of branch insertion rods 15 are divided into two groups, one group is horizontally arranged, and the other group is gradually upwardly inclined from the center of the main insertion rod 14 to the outside. The pull rod 37 is provided with a ring frame 40 in transmission cooperation therewith, the ring frame 40 is respectively provided with a plurality of horizontal sliding grooves 41 and inclined sliding grooves 42, the end portions of the branch insertion rods 15 arranged in the horizontal sliding grooves 41 are slidably arranged in the horizontal sliding grooves 41, and the end portions of the branch insertion rods 15 arranged in the horizontal sliding grooves 41 are slidably arranged in the inclined sliding grooves 42.

[0041] When it is needed to insert the sub-inserting rod 15 into the soil layer, the ring frame 40 which is in transmission connection with the pull rod 37 is driven to move upward by the upward movement of the pull rod 37, at the same time, the end part of the obliquely arranged sub-inserting rod 15 moves outward along the horizontal sliding groove 41, thereby being inserted into the soil layer along the obliquely arranged guiding limiting hole 39; the end part of the horizontally arranged sub-inserting rod 15 moves outward along the obliquely arranged sliding groove 42, thereby being inserted into the soil layer along the horizontally arranged guiding limiting hole 39 while keeping the horizontal height unchanged.

[0042] The two groups of sub-inserting rods 15 which are arranged in different directions can support and reinforce the main inserting rod 14 from multiple angles. The horizontally arranged sub-inserting rod 15 increases the horizontal anti-pulling force, preventing the drilling machine from being displaced when subjected to horizontal external force (such as wind force, horizontal force generated by ground vibration, etc.). The obliquely arranged sub-inserting rod 15 enhances the oblique anti-pulling force, improving the stability of the drilling machine under different terrain and geological conditions, so that the drilling machine can also be firmly fixed in complex environments such as soft soil and slope, effectively improving the stability and reliability of the drilling operation.

[0043] The main inserting rod 14 is provided with an annular mounting groove, a blocking ring 43 which closes the guiding limiting hole 39 is slidably arranged in the annular mounting groove, a transmission ring 44 is slidably arranged on the pull rod 37, the transmission ring 44 is fixedly connected with the blocking ring 43 through a transmission frame 45, a spring 46 is arranged between the transmission ring 44 and the bottom of the pull rod 37, the two ends of the spring 46 are respectively fixedly connected with the bottom of the transmission ring 44 and the bottom of the pull rod 37, and the pull rod 37 is further provided with a limiting ring 47 which can abut against the ring frame 40.

[0044] The blocking ring 43 is used to block the guide limiting hole 39, which is used in the process of inserting or pulling out the main insertion rod 14. When the main insertion rod 14 is in the two states, the guide limiting hole 39 can be closed to prevent soil from entering the inside of the main insertion rod 14, causing internal blockage. After the main insertion rod 14 is inserted into place, the pull rod 37 can drive the blocking ring 43 to run upward. The pull rod 37 has two strokes, and the blocking ring 43 is closed when the pull rod 37 is at the lowest position. The bottom of the pull rod 37 is connected to the blocking ring 43 through the transmission ring 44 and the transmission frame 45. When external expansion is needed, the blocking ring 43 needs to be opened upward first. The pull rod 37 rises, and the blocking ring 43 rises synchronously with the pull rod 37 through the transmission ring 44 and the transmission frame 45. At this time, the ring frame 40 does not displace, and the pull rod 37 slides relative to the ring frame 40. Only the blocking ring 43 moves upward in this stroke. When the blocking ring 43 moves into place in the ring-shaped mounting groove, the pull rod 37 performs a second stroke. The limiting ring 47 fixedly arranged on the pull rod 37 abuts against the ring frame 40, and the ring frame 40 moves upward synchronously through the limiting ring 47. At this time, the blocking ring 43 does not move when the drive split insertion rod 15 displaces. When resetting, the pull rod 37 descends, and the split insertion rod 15 resets. At this time, the spring 46 recovers and continues to descend, and the spring 46 drives the transmission ring 44 to displace, and the transmission frame 45 drives the blocking ring 43 to reset.

[0045] The drilling machine device 10 includes a drilling motor 48, a rotating connection seat 49, and a drill rod clamping jaw 50 for stabilizing and limiting the drill rod. The drilling motor 48 is installed on the lifting frame 9 and is in transmission connection with the rotating connection seat 49. The drill rod clamping jaw 50 is installed on the lifting frame 9 and is located directly below the rotating connection seat 49.

[0046] Before drilling operation, according to different folding states of the drilling frame 6 and actual drilling requirements, a drill rod with a suitable length (a long drill rod or a short drill rod) is selected. The selected drill rod is installed between the rotating connection seat 49 and the drill rod clamping jaw 50, and the installation is ensured to be firm. The drilling motor 48 drives the drill rod connected thereto to rotate at high speed through the rotating connection seat 49. In the process of rotating the drill rod, the drill rod clamping jaw 50 provides stable support and limitation for the drill rod, preventing the drill rod from shaking, deviating, or falling off during high-speed rotation. With the lifting frame 9 sliding up and down on the drilling frame 6, the drill rod can penetrate into the ground to different depths for drilling, thereby obtaining geological samples or performing related geological survey work.
