Description

Technical Field

[0001] This utility model relates to the field of drill arm technology, specifically to a drill arm adjustment device and a medium-deep hole platform having the same. Background Technology

[0002] The medium-deep hole trolley is a special equipment used in mining, tunnel and other engineering projects for medium-deep hole drilling operations. Medium-deep holes usually refer to holes with a depth of 5-50 meters. The core component of the medium-deep hole trolley is the drill arm structure, whose main function is to support and move the propeller to achieve adjustment of the drilling position and angle.

[0003] In the existing technology, when a medium-deep hole trolley is operating, after it travels to the work site, starts the work mode to drill the end face of the rock wall, and then needs to work on the adjacent face, it is necessary to start the medium-deep hole trolley, move it to the adjacent position, and then restart the work.

[0004] Its operation mode, which requires frequent relocation, results in low construction efficiency. Utility Model Content

[0005] In view of this, the present invention provides a drill arm adjustment device and a medium-deep hole trolley having the same, to solve the problem that the existing medium-deep hole trolley design requires frequent movement to operate multiple holes, resulting in low construction efficiency.

[0006] In a first aspect, this utility model provides a drill arm adjustment device, comprising: a base, the base being rotatably connected to a medium-deep hole trolley;

[0007] A first driving component is disposed on the deep hole trolley. The driving end of the first driving component is rotatably connected to the base, and the fixed end of the first driving component is rotatably connected to the deep hole trolley. The first driving component drives the base to rotate in a vertical plane. A sliding component is disposed on the base, and a slider is disposed on the sliding component. The sliding component is used to drive the slider to move along the length direction of the base. A rotating assembly is mounted on a slider. A drill rod assembly is mounted on the driving end of the rotating assembly. The rotating assembly drives the drill rod assembly to rotate in a plane parallel to the upper surface of the base. A drill rod assembly for drilling is mounted on the rotating assembly.

[0008] By rotating the base onto the deep hole trolley, the base is driven to rotate in the vertical plane by the first drive component, thereby adjusting the pitch angle of the drill arm. In conjunction with the sliding component, the slider moves along the length of the base, achieving precise adjustment of the drill arm's front and rear positions. Then, the drill rod assembly is driven to rotate in the horizontal plane by the rotating component, thereby adjusting the azimuth angle of the drill rod assembly. This allows multiple drilling positions to be covered in a single positioning, reducing the number of times the deep hole trolley needs to be moved and improving work efficiency.

[0009] In one optional embodiment, the slider is provided with a swing arm parallel to the upper surface of the base, the first end of the swing arm is connected to the slider, and the second end of the swing arm is provided with a rotating component.

[0010] By setting the rotating component to rotate in the horizontal plane, the drill rod assembly is driven to achieve angle adjustment. Combined with the linear motion of the sliding component and the pitch control of the base by the first driving component, a three-dimensional spatial linkage adjustment mechanism is formed, enabling the drill arm to complete precise positioning of multiple holes without moving the trolley.

[0011] In one optional embodiment, the first end of the swing arm is rotatably connected to the slider, and a second driving member is provided on at least one side of the swing arm. One end of the second driving member is rotatably connected to the slider, and the driving end of the second driving member is rotatably connected to the swing arm. The second driving member is used to drive the swing arm to rotate in a plane parallel to the upper surface of the base.

[0012] By rotatably connecting one end of the swing arm to the slider, and driving the other end of the swing arm to rotate in a plane parallel to the upper end of the base through a second driving component, a small-amplitude rotation of the swing arm is achieved.

[0013] In one alternative embodiment, the second drive member has two symmetrically arranged on both sides of the rocker arm.

[0014] By setting two second drive components, the swing arm can be rotated more precisely, ensuring its stability during rotation and avoiding uneven force and swaying problems caused by unilateral drive, thereby further improving the accuracy and reliability of drill arm adjustment.

[0015] In one alternative embodiment, the rotating assembly includes a third drive member and a mounting member, the mounting member being rotatably disposed at the end of the rocker arm facing away from the base, the axis of the mounting member being perpendicular to the upper end face of the base, and the mounting member being disposed on the side of the drill rod assembly facing away from the base.

[0016] By setting a third driving component, the drill rod assembly is driven to rotate, so that the drill rod assembly rotates in a plane parallel to the upper surface of the base. The drill rod assembly can be rotated to multiple preset drilling positions on the base. Combined with the adjustment of the base pitch angle by the first driving component, the control of the horizontal rotation of the swing arm by the second driving component, and the rotation of the drill rod assembly around the axis by the third driving component, the drill rod assembly can achieve multi-degree-of-freedom coordinated movement in space, thus expanding the range of operation.

[0017] In one alternative embodiment, the sliding assembly includes two symmetrically arranged slide rails that extend toward the length direction of the base.

[0018] By setting two slide rails that jointly support the drill rod assembly, the stability and load-bearing capacity of the drill rod assembly during the sliding process can be improved, ensuring that the drill rod assembly will not deviate or shake when moving along the length of the base, thus guaranteeing the accuracy and quality of the drilling operation.

[0019] Secondly, this utility model also provides a medium-deep hole trolley, including: a support frame, one end of which is provided with a receiving cavity, the receiving cavity being used to install the drill arm adjustment device as described in any of the above solutions.

[0020] By setting the drill arm adjustment device in the receiving cavity at one end of the support frame, the drill arm adjustment device can be retracted into the receiving cavity when drilling is not required, which facilitates the movement of the medium-deep hole trolley. When drilling is required, the drill arm adjustment device can be activated to carry out drilling.

[0021] In one alternative embodiment, a rotating shaft is provided between two opposite sides of the receiving cavity, and the base is rotatably mounted on the rotating shaft.

[0022] By setting a rotating shaft in the receiving cavity and rotating it to the base, the base can rotate flexibly around the rotating shaft as the axis, thereby cooperating with the first drive component to achieve precise pitch adjustment of the drill arm in the vertical plane, effectively improving the flexibility of drill arm adjustment and expanding the working range.

[0023] In one optional embodiment, the first driving member is disposed within the receiving cavity, one end of the first driving member is rotatably connected to the inner wall of the receiving cavity, and the driving end of the first driving member is rotatably connected to the base.

[0024] By setting one end of the first driving component to be rotatably connected to the inner wall of the receiving cavity, the first driving component is placed inside the receiving cavity, thereby reducing the area occupied by the first driving component.

[0025] In one alternative embodiment, the first driving component is a hydraulic cylinder. By setting the hydraulic cylinder to drive the base to rotate, the base can be flipped. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0031] like Figure 1 , Figure 2As shown, according to an embodiment of the present invention, a drill arm adjustment device is provided, comprising: a base 1, a rotating device, a sliding assembly 4, and a first driving member 3. The base 1 is rotatably connected to a deep-hole trolley 2. The first driving member 3 is disposed on the deep-hole trolley 2, with its driving end rotatably connected to the base 1 and its fixed end rotatably connected to the deep-hole trolley 2, wherein the fixed end of the first driving member 3 refers to the side away from the driving end. The first driving member 3 drives the base 1 to rotate in a vertical plane, wherein the vertical plane refers to the surface formed by the rotation of the base 1 being a vertical surface. Specifically, the base 1 has a horizontal state and a vertical state, and the first driving member 3 can stop at the corresponding angle in both states as needed. The sliding assembly 4 is disposed on the upper surface of the base 1, and a slider 7 is disposed on the sliding assembly 4. The sliding assembly 4 drives the slider 7 to move along the length direction of the base 1. The rotating assembly 5 is disposed on the slider 7, and a drill rod assembly 6 is disposed on the driving end of the rotating assembly 5. The rotating assembly 5 drives the drill rod assembly 6 to rotate in a plane parallel to the upper surface of the base 1.

[0032] Under normal conditions, the drill arm adjustment device retracts, the base 1 is horizontal, and the extension direction of the drill rod assembly 6 is parallel to the extension direction of the vehicle body of the deep-hole trolley 2. When drilling is required, the hydraulic outriggers of the deep-hole trolley 2 extend and rest against the ground for support. When the base 1 is horizontal, the rotating assembly 5 can drive the drill rod assembly 6 to rotate, thereby drilling holes in the rock walls on both sides or the rear of the vehicle body. The sliding assembly 4 can also drive the rotating assembly 5 to move towards the rock wall, bringing the drill rod assembly 6 closer to the rock wall for easier drilling.

[0033] Simultaneously, the first driving component 3 drives the base 1 to rotate, causing the base 1 to bring the drill rod assembly 6 into a vertical position, or the base 1 to remain inclined to the horizontal plane, enabling the drill rod assembly 6 to drill holes in the rock walls on both sides or the rear of the vehicle. Taking the base 1 as an example, when the drill rod assembly 6 is in a vertical downward position, it can drill holes vertically downward in the area behind the vehicle. Alternatively, the rotating component 5 drives the drill rod assembly 6 to rotate, allowing it to be in a horizontal position for drilling holes in the rock wall horizontally, or inclined downward or upward for drilling holes in an inclined direction. The rotating component 5 can drive the drill rod assembly 6 to stop at any angle, which can be adjusted according to actual needs during construction; this embodiment will not elaborate further.

[0034] Specifically, the structure of the drill rod assembly 6 of the medium-deep hole trolley 2 is existing technology. The medium-deep hole trolley 2 refers to a mechanical device used for medium-deep hole drilling operations, typically used in mining, tunnel construction, or geological exploration. The drill rod assembly 6 is one of the core components of the medium-deep hole trolley 2, mainly used to transmit the power of the drilling rig to the drill bit and complete the drilling operation. It consists of drill rods, connectors, stabilizers, etc. In this embodiment, the drill rod assembly 6 and the rotating assembly 5 are fixedly connected by bolts. The specific connection method and construction process are existing designs and will not be described in detail in this embodiment.

[0035] By rotating the base 1 onto the deep hole trolley 2, the base 1 is driven to rotate in the vertical plane by the first drive component 3, thereby adjusting the pitch angle of the drill arm. In conjunction with the sliding component 4, the slider 7 is moved along the length of the base 1, achieving precise adjustment of the front and rear positions of the drill arm. Then, the drill rod assembly 6 is driven to rotate in the horizontal plane by the rotating component 5, thereby adjusting the azimuth angle of the drill rod assembly 6. This allows multiple drilling positions to be covered in a single positioning, reducing the number of times the deep hole trolley 2 needs to be moved and improving work efficiency.

[0036] Specifically, the first driving component 3 is a hydraulic cylinder. Alternatively, the first driving component 3 can also be a linear motor.

[0037] like Figure 1 As shown, in this embodiment, a rocker arm 8 parallel to the upper surface of the base 1 is provided on the slider 7. The first end of the rocker arm 8 is connected to the slider 7, and the second end of the rocker arm 8 is provided with a rotating component 5. The second end of the rocker arm 8 extends toward one side of the deep hole trolley 2. When the base 1 is in a horizontal state, the sliding component 4 drives the slider 7 to move toward one side of the deep hole trolley 2. At this time, the drill rod assembly 6 moves toward the deep hole trolley 2, so that the parts are more compact when not drilling, thereby reducing the area occupied by the deep hole trolley 2 and facilitating the movement of the deep hole trolley 2. By setting the rotating component 5 to rotate in the horizontal plane, the drill rod assembly 6 is driven to achieve angle adjustment. Combined with the linear motion of the sliding component 4 and the pitch control of the base 1 by the first driving component 3, a three-dimensional spatial linkage adjustment mechanism is formed, so that the drill arm can complete the precise positioning of multiple holes without moving the trolley. It should be noted that, as an alternative implementation, the rocker arm 8 can be omitted, and the rotating component 5 can be directly set on the slider 7.

[0038] like Figure 1As shown, in this embodiment, the first end of the rocker arm 8 is rotatably connected to the slider 7. At least one side of the rocker arm 8 is provided with a second driving member 9, where "at least one side" refers to at least one side in the width direction of the rocker arm 8. One end of the second driving member 9 is rotatably connected to the slider 7, and the driving end of the second driving member 9 is rotatably connected to the rocker arm 8. The second driving member 9 is used to drive the rocker arm 8 to rotate in a plane parallel to the upper surface of the base 1. By rotatably connecting one end of the rocker arm 8 to the slider 7 and driving the other end to rotate in a plane parallel to the upper surface of the base 1 via the second driving member 9, a small-amplitude rotation of the rocker arm 8 is achieved. When the drill rod assembly 6 is drilling, the second driving member 9 can correct the deviation of the drill rod assembly 6 during drilling. The second driving member 9 drives the rocker arm 8 to rotate, thereby causing the rotating assembly 5 and the drill rod assembly 6 to rotate slightly. Specifically, the second driving member 9 is a hydraulic cylinder, which has a large driving force, facilitating the rotation of the rocker arm 8 for deviation correction during drilling. It should be noted that, as an alternative implementation, the rocker arm 8 can also be fixedly connected to the slider 7, and the drill rod assembly 6 can be rotated by the rotating component 5.

[0039] Specifically, the swing arm 8 is a rectangular body, with one end rotatably connected to the slider 7 along its length, and the other end mounted with a rotating component 5. The slider 7 has a mounting plate, which is spaced apart above the slider 7. Vertical plates extend vertically downwards from both ends of the mounting plate along the width direction of the swing arm 8, and these vertical plates are integrally formed with the mounting plate. A space is formed between the mounting plate and the slider 7 to accommodate the first end of the swing arm 8. The swing arm 8 is inserted between the mounting plate and the slider 7. A rotation axis passes sequentially through the mounting plate and the swing arm 8 from above, and the swing arm 8 oscillates around the rotation axis.

[0040] Specifically, a rotating seat is provided on the vertical plate, and the fixed end of the second rotating component is rotatably connected to the rotating seat. The axis of rotation of the second rotating component is perpendicular to the upper surface of the slider 7, so that the second rotating component drives the rocker arm 8 to rotate in a plane parallel to the upper surface of the slider 7. The structure of the rotating seat and the structure of the rotating component rotatably connected to the rocker arm 8 are existing designs, and will not be described in detail in this embodiment.

[0041] Specifically, the correction mechanism of drill rod assembly 6 is based on the existing design. During actual operation, the real-time control of the swing arm 8 via the second drive component 9 effectively addresses drilling deviations caused by changes in geological conditions or equipment vibration. When the sensor detects an angular shift in drill rod assembly 6, the control system activates the second drive component 9, which uses the extension and retraction of the hydraulic cylinder to make minor adjustments to the swing arm 8, ensuring that the drill rod always maintains the preset drilling trajectory. Furthermore, the rotating assembly 5 employs a worm gear transmission structure, which has self-locking characteristics, enabling the drill rod assembly 6 to maintain positional stability even when subjected to significant reaction forces.

[0042] Specifically, there are two second drive components 9, symmetrically arranged on both sides of the rocker arm 8. The driving method of the two second drive components 9 is as follows: the driving end of one second drive component 9 retracts, while the other second drive component 9 extends outward, causing the second end of the rocker arm 8 to rotate around the rotation point of the first end, thereby realizing the rotation of the rocker arm 8 and thus adjusting the angle of the drill pipe assembly 6. By setting two second drive components 9, the rotation of the rocker arm 8 can be more precise, ensuring the stability of the rocker arm 8 during rotation, avoiding uneven force and swaying problems caused by unilateral drive, and further improving the accuracy and reliability of drill arm adjustment.

[0043] like Figure 1 As shown, in this embodiment, the rotating assembly 5 includes a third driving member and a mounting member 10. The mounting member 10 is rotatably disposed at the end of the swing arm 8 facing away from the base 1, and the mounting member 10 has a circular plate-like structure. The third driving member drives the mounting member 10 to rotate. The axis of the mounting member 10 is perpendicular to the upper surface of the base 1, and the mounting member 10 is disposed on the side of the drill rod assembly 6 facing away from the base 1. When rotation is required, the third driving member drives the mounting member 10 to rotate, and the drill rod assembly 6 is mounted on the mounting member 10, causing the mounting member 10 to rotate. The drill rod assembly 6 is parallel to the mounting member 10, and the end of the drill rod assembly 6 along its length away from the drill hole is connected to the mounting member 10. By setting a third driving component, the drill rod assembly 6 is driven to rotate, causing it to rotate in a plane parallel to the upper surface of the base 1. This allows the drill rod assembly 6 to be rotated to multiple preset drilling positions on the base 1. Combined with the adjustment of the pitch angle of the base 1 by the first driving component 3, the control of the horizontal rotation of the swing arm 8 by the second driving component 9, and the rotation of the drill rod assembly 6 around its axis by the third driving component, multi-degree-of-freedom coordinated motion of the drill rod assembly 6 in space is achieved, increasing its operational range. The third driving component is a motor. It should be noted that, as an alternative implementation, the rotating component 5 may also include a sensor. The sensor detects the rotation angle of the mounting component 10 to determine the current position of the drill rod assembly 6. The sensor can be an angle sensor.

[0044] Specifically, a circular fixing member is provided at the second end of the rocker arm 8. The fixing member is annular, and its axis is perpendicular to the upper surface of the base 1. The mounting member 10 is rotatably positioned at the upper opening of the annular fixing member. The lower opening of the fixing member is sealed by a circular plate. The third drive member is mounted on the circular plate, and the worm gear is located inside the fixing member. The worm gear is connected to the mounting member 10, and the worm is fixedly connected to the output shaft of the third drive member. When the third drive member is activated, the worm rotates accordingly. Through the transmission action of the worm gear, the mounting member 10 is driven to rotate above the fixing member, thereby achieving precise angle adjustment of the drill pipe assembly 6 in the horizontal plane.

[0045] Specifically, the drill rod assembly 6 is provided with a flange connected to the mounting member 10, and after the flange abuts against the mounting member 10, the flange and the mounting member 10 are fixed by bolts.

[0046] As Figure 1 shown, in this embodiment, the sliding assembly 4 comprises two symmetrically arranged slide rails 11, and the slide rails 11 extend toward the length direction of the base 1. Specifically, the slide rails 11 are electric slide rails 11. By arranging two slide rails 11, the two slide rails 11 jointly support the drill rod assembly 6, which can improve the stability and bearing capacity of the drill rod assembly 6 during sliding, ensure that the drill rod assembly 6 does not deviate or shake when moving along the length direction of the base 1, and guarantee the accuracy and quality of the drilling operation. It should be noted that, as an alternative embodiment, the sliding assembly 4 may also be provided with only one slide rail 11. In addition, an electric cylinder may also be used to drive the sliding block 7 to move on the slide rail 11.

[0047] As Figure 2 shown, in a second aspect, the present utility model further provides a medium-deep hole jumbo 2, comprising: a support frame 12, one end of the support frame 12 is provided with an accommodating cavity. The support frame 12 is fixedly connected with the underframe assembly of the medium-deep hole jumbo 2. The support frame 12 is located at the tail of the vehicle body. The shape of the support frame 12 is similar to a "door" shape, which comprises three mutually perpendicular first fixing plate, second fixing plate and third fixing plate, wherein the second fixing plate and the third fixing plate are arranged in parallel at an interval, the second fixing plate and the third fixing plate are respectively vertically arranged at two ends of the first fixing plate, and the first fixing plate, the second fixing plate and the third fixing plate enclose to form the accommodating cavity. The ends of the second fixing plate and the third fixing plate away from the first fixing plate are rotatably provided with the base 1. The fixed end of the first driving member 3 is rotatably connected with the first fixing plate, and the driving end is rotatably connected with the base 1. The accommodating cavity is used for installing the drill boom adjusting device according to any one of the above schemes. By arranging the drill boom adjusting device in the accommodating cavity at one end of the support frame 12, when drilling is not required, the drill boom adjusting device is retracted into the accommodating cavity, which facilitates the movement of the medium-deep hole jumbo 2, and when drilling is required, the drill boom adjusting device is activated to perform drilling.

[0048] As Figure 2As shown, in this embodiment, a rotating shaft is provided between two opposite sides of the receiving cavity, and the base 1 is rotatably mounted on the rotating shaft. The two opposite sides refer to the sides of the second and third fixed plates facing each other. By providing a rotating shaft within the receiving cavity and rotatably connecting it to the base 1, the base 1 can rotate flexibly around the rotating shaft, thereby cooperating with the first drive component 3 to achieve pitch adjustment of the drill arm in the vertical plane, effectively improving the flexibility and working range of the drill arm adjustment. It should be noted that, as an alternative implementation, two rotating shafts can also be provided, with the two rotating shafts respectively mounted on the second and third fixed plates, and the two ends of the base 1 in the width direction rotatably connected to the two rotating shafts respectively.

[0049] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
