Description

Technical Field

[0001] This invention relates to the field of mining engineering construction technology, specifically to a portable auxiliary device for measuring mine elevation. Background Technology

[0002] In the process of mine engineering construction and mineral resource development, elevation measurement is a crucial link in controlling project quality and ensuring production safety. Its measurement accuracy and efficiency directly affect mine roadway design, ore body positioning, and mining planning. However, a prominent problem currently facing mine elevation measurement work is that existing auxiliary equipment is difficult to adapt to the complex operating environment of mines, and has significant limitations in terms of mobility, support stability, horizontal calibration accuracy, and multi-dimensional adjustment coordination.

[0003] There is a contradiction between the mobility and support design of traditional mine elevation measurement auxiliary equipment: fixed measuring brackets can provide stable support, but they are bulky and heavy, requiring cranes or multiple people to move them in narrow tunnels, steep slopes and other terrains, resulting in extremely low transfer efficiency and an inability to flexibly adapt to the rapid switching of different measurement points; portable equipment, although using simple folding structures or single-leg support to improve mobility, has a rudimentary support structure, is prone to settlement on soft slag ground in mines, and the leveling process requires repeated manual operation, which is difficult to compensate for ground unevenness, resulting in poor equipment stability and directly affecting the reliability of the measurement benchmark.

[0004] In terms of level calibration, existing technologies are ill-equipped to handle the dynamic interference of the mining environment: manual bubble leveling relies on the operator's experience, resulting in large fluctuations in calibration accuracy. Furthermore, the vibrations from mine blasting and the impact of equipment operation can cause the calibrated level to fail in a short period of time, requiring frequent recalibration. Although electronic automatic leveling systems can achieve electric adjustment, the strong electromagnetic interference in the mining environment (such as motor start signals and blasting electromagnetic pulses) can easily cause sensor misjudgments. Moreover, the leveling function is completely lost when there is a power outage or equipment failure, making it impossible to guarantee a continuous level reference during the measurement process.

[0005] Insufficient precision and coordination in multi-dimensional adjustments are also key factors restricting measurement efficiency: Elevation adjustments often employ single-screw drives or hydraulic lifting structures. Single-screw drives are prone to swaying due to uneven loads, causing the optical axis of the measuring instrument to tilt. Hydraulic structures pose a risk of leakage, and their adjustment accuracy is affected by oil pressure fluctuations. Azimuth adjustments mostly rely on gear meshing transmissions. Traditional gear clearances are prone to angular hysteresis, and there is a lack of intuitive angle quantification indicators, making it difficult to achieve accurate azimuth positioning. Furthermore, elevation, level, and azimuth adjustment systems often operate independently, requiring separate operation and interfering with each other during adjustment. This fails to meet the rapid switching requirements of "multiple measurements at one point" scenarios in mines, significantly extending the preparation time for a single measurement. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Existing mining surveying equipment has significant shortcomings in terms of balance between movement and support. Traditional fixed equipment requires cranes or multiple people to carry it, making it almost impossible to move in narrow tunnels and steep slopes in mining environments. Simple portable equipment often uses a single leg or folding bracket, resulting in a small support area and difficulty in leveling. It is also prone to settling on soft slag surfaces. This equipment's casters are made of highly elastic and wear-resistant rubber, with anti-slip grooves on the rims, allowing it to easily cross gravel protrusions. Combined with the streamlined outer contour of the equipment base, it can flexibly turn within mining tunnels. Once it reaches the measurement point, the four sets of base support blocks are arranged in a rectangular pattern. By rotating the screw handle, the support adjustment screw is driven to rotate, ensuring that the anti-slip grounding pads are in close contact with the ground. This allows it to adapt to sloping ground. By adjusting the height of the four support points individually, the casters can be completely lifted off the ground, and the horizontal deviation of the equipment base can be controlled within a reasonable range. The leveling time is significantly reduced compared to traditional tripod support, and the support stability is significantly improved compared to equipment of the same weight.

[0019] Existing horizontal calibration methods have significant limitations. Manual bubble leveling requires repeated adjustments and its accuracy is affected by the operator's experience; in a vibrating mining environment, the horizontal deviation may be large in a short period of time. Although electronic automatic leveling systems can achieve electric correction, the sensors are susceptible to electromagnetic interference in the mine, leading to misjudgments, and they completely fail when power is off. The gravity leveling mechanism of this equipment adopts a purely mechanical structure design. The fit between the leveling bracket and the ball joint seat is extremely small, and the main gravity ball and the ball joint seat form a low-friction spherical contact. The secondary gravity ball connected by the balance link and the spherical balance track form a dual guide. When the equipment tilts due to mine blasting vibration or personnel contact, the main gravity ball will immediately rotate under the action of gravity torque, driving the secondary gravity ball to roll along the spherical balance track. The entire adjustment process is lag-free, and the deviation remains within a very small range after horizontal stabilization. It can still work normally in the event of a sudden power outage or strong electromagnetic interference in the mine, significantly improving its environmental adaptability compared to electronic leveling systems.

[0020] Existing equipment has significant shortcomings in multi-dimensional adjustment. For elevation adjustment, the single-screw driven lifting structure is prone to swaying due to uneven load, causing the instrument's optical axis to tilt. For azimuth adjustment, the backlash in traditional gear transmissions causes angular hysteresis, and the lack of an intuitive angle reading device makes precise angle positioning difficult. This equipment employs a dual-main-support-column synchronous drive design for elevation adjustment. Two elevation screws are synchronously driven by the same type of lifting drive motor. The sliding guide rail between the lifting guide column and the main support column ensures minimal vertical deviation of the instrument assembly plate during lifting. In the azimuth adjustment system… The meshing transmission between the rotary gear ring and the transmission worm gear allows the azimuth adjustment disc to rotate at a moderate angle. Combined with the alignment of the angle measuring gauge and the azimuth pointer, high-precision angle adjustment can be achieved. More importantly, the elevation, level, and azimuth adjustment systems can work together. For example, while adjusting the elevation, the gravity leveling mechanism will correct the horizontal deviation in real time. When rotating the azimuth adjustment disc, the elevation position remains stable, meeting the continuous measurement needs of mines for "multiple directions and multiple heights at the same measuring point". This significantly shortens the preparation time for a single measurement and significantly improves efficiency compared to the step-by-step adjustment method of traditional equipment.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6As shown, the present invention provides a technical solution: a portable mine elevation measurement auxiliary device, comprising an equipment base 1, an elevation lifting mechanism 3, an instrument mounting and adjusting structure 9, a gravity stabilizing mechanism 10, and an azimuth rotation mechanism 11, which can efficiently assist in mine elevation measurement work. The bottom of the equipment base 1 is equipped with casters 15 to improve mobility. The base support blocks 11 around the base are connected with threaded support adjustment screws 12. By rotating the screws and rotating the handles 13, the height of the anti-slip grounding pads 14 can be adjusted to achieve stable placement of the equipment. The main support columns 2 on both sides of the upper end of the base have built-in elevation... The screw 22 has a column buffer pad 21 at its top, which provides protection and limit for the lifting structure. The elevation lifting mechanism 3 is threadedly engaged with the elevation screw 22 through the lifting guide column 31 in the main support column 2. Driven by the lifting drive motor 33, it drives the L-shaped measuring tool support plate 32 and the measuring tool bearing plate 34 to move up and down, thereby realizing the elevation adjustment of the instrument assembly plate 4 to meet different measurement height requirements. In the stabilizing counterweight box 5 at the lower end of the instrument assembly plate 4, the gravity stabilizing mechanism 10 uses the ball joint socket 102 and the gravity main ball 103 connected by the stabilizing bracket 101 to cooperate with the balance link. The lower end of rod 104 is attached to the spherical balance track 106 by a gravity-assisted ball 105, which automatically calibrates the horizontal state of the equipment by gravity, ensuring the stability of the measurement benchmark. The front end of the drive control module 6 at the upper end of the mounting plate is equipped with an angle measuring gauge 61. The instrument mounting and adjustment structure 9 at its upper end can quickly lock the instrument clamping plate 71 of the instrument protective box 7 through the instrument clamping seat 92, the mounting and adjustment fixing hook 93 and the mounting and adjustment reset spring 95 on the instrument mounting plate 91. The instrument embedding slot 74 in the protective box fixes the elevation measuring instrument host 8 through the instrument positioning plate 75 and the instrument limiting spring pad 76. The window 72 and the protective box cover 73 facilitate the operation and protection of the equipment. The azimuth rotation mechanism 11 inside the drive control module 6 engages with the transmission worm gear 113 of the azimuth drive rod 112 by rotating the rotation ring 111 at the outer end of the adjustment shaft 96. Rotating the azimuth adjustment disk 114 with the azimuth pointer 115 at the front end can adjust the horizontal azimuth of the instrument mounting structure 9 and read the angle through the angle measuring gauge 61 to improve the accuracy of the measurement azimuth. This equipment integrates the functions of movement, lifting, leveling, azimuth adjustment and instrument fixing. It is highly portable and can effectively improve the efficiency and accuracy of mine elevation measurement.

[0030] according to Figure 1 and Figure 2As shown, the equipment base 1 is the basic load-bearing structure of this portable mine elevation measurement auxiliary equipment. Universal wheels 15 are installed around its lower surface, greatly improving the overall mobility of the equipment and facilitating flexible transport in complex mining environments. Base support blocks 11 are fixedly connected to the outer surfaces of the equipment base 1. Each base support block 11 has a threaded hole in its center, with an internal threaded support adjusting screw 12. A screw rotation handle 13 is installed at the upper end of the support adjusting screw 12, and its lower end extends to the lower end of the equipment base 1 and is fitted with an anti-slip grounding pad 14. By rotating the screw and rotating the handle 13, the extension length of the support adjusting screw 12 can be adjusted, thereby adjusting the contact state between the anti-slip grounding pad 14 and the ground, achieving stable placement of the equipment in different terrains and providing a stable support foundation for the entire measurement equipment. Simultaneously, main support columns 2 are fixedly connected to both sides of the upper surface of the equipment base 1, providing an installation carrier for subsequent elevation lifting and other mechanisms.

[0031] according to Figure 1 and Figure 3 As shown, the main support column 2 is the basic support component for equipment elevation adjustment. Two main support columns 2 are fixedly connected to both sides of the upper surface of the equipment base 1. An elevation screw 22 is installed in the center of each column, with its upper end extending to the outside of the upper end of the main support column 2. Column buffer pads 21 are fixedly installed on the upper surface of each of the two main support columns 2, providing buffer protection during the elevation lifting mechanism 3's lifting process. The elevation lifting mechanism 3 is used to adjust the elevation of the measuring instrument and includes a lifting guide column 31, an L-shaped measuring tool support plate 32, a lifting drive motor 33, and a measuring tool bearing plate 34. Lifting guide columns 31 are respectively fitted inside the upper ends of the two main support columns 2, with their upper ends extending to the outside of the upper end of the main support column 2 and fixedly connected to an L-shaped... The measuring tool support plate 32 is bolted to the inner side of the upper end of the L-shaped measuring tool support plate 32 and to the outer sides of the instrument assembly plate 4. The threaded hole in the center of the lifting guide column 31 is threaded onto the outer end of the elevation screw 22. The output end of the lifting drive motor 33 installed on the inner surface of the L-shaped measuring tool support plate 32 is connected to the upper end of the elevation screw 22. The upper end of the inner surface of the two L-shaped measuring tool support plates 32 is also connected to the measuring tool support plate 34, and its upper surface abuts against the lower surface of the instrument assembly plate 4. The elevation screw 22 is driven to rotate by the lifting drive motor 33. With the threaded transmission between the lifting guide column 31 and the elevation screw 22, the L-shaped measuring tool support plate 32 and the measuring tool support plate 34 are moved up and down, thereby realizing the elevation adjustment of the instrument assembly plate 4 and the measuring components above it.

[0032] according to Figure 1 and Figure 4As shown, the gravity stabilizing mechanism 10 is installed inside the stabilizing counterweight box 5 to ensure the horizontal stability of the equipment during measurement. It includes a stabilizing bracket 101, a ball joint socket 102, a main gravity ball 103, a balance link 104, a secondary gravity ball 105, and a spherical balance track 106. The spherical balance track 106 is fixedly installed at the lower end of the stabilizing counterweight box 5, and the stabilizing bracket 101 is fixedly installed at the upper end. The lower center of the stabilizing bracket 101 is movably connected to the ball joint socket 102, and the lower end of the ball joint socket 102 is movably connected to the gravity ball joint. The main ball 103 is fixedly connected to the bottom surface of the gravity main ball 103 with a balance link 104. The lower end of the balance link 104 extends to the center of the spherical balance track 106 and is fixedly installed with a gravity auxiliary ball 105. The gravity auxiliary ball 105 is in close contact with the inner wall of the spherical balance track 106. With the help of gravity, the movement of the gravity main ball 103 and the gravity auxiliary ball 105 in the ball joint seat 102 and the spherical balance track 106, in conjunction with the balance link 104, can automatically calibrate the horizontal state of the equipment and provide a stable reference for measurement.

[0033] Furthermore, the azimuth rotation mechanism 11 is installed inside the drive control module 6 and is used to adjust the horizontal azimuth of the measuring instrument. It includes a rotary gear ring 111, an azimuth drive rod 112, a transmission worm gear 113, an azimuth adjustment disc 114, and an azimuth pointer 115. Inside the drive control module 6, the rotary gear ring 111 is fixedly mounted on the outer surface of the rotation adjustment shaft 96. An azimuth drive rod 112 is provided on one side inside the drive control module 6, and a transmission worm gear 113 is mounted on its outer surface. The outer end of the transmission worm gear 113 meshes with the outer end of the rotary gear ring 111. The front end of the azimuth drive rod 112 extends to the drive control module 6. The front end of the control module 6 is externally mounted with an azimuth adjustment disk 114, which is correspondingly positioned at the front end of the angle measuring gauge 61. An azimuth pointer 115 is set on one side of the outer end of the azimuth adjustment disk 114, which corresponds to the angle measuring gauge 61. Rotating the azimuth adjustment disk 114 drives the transmission worm gear 113 to rotate through the azimuth drive rod 112, which in turn meshes with and drives the rotary gear ring 111 and the rotation adjustment shaft 96, thereby realizing the horizontal azimuth adjustment of the instrument mounting structure 9. At the same time, through the cooperation of the azimuth pointer 115 and the angle measuring gauge 61, the adjustment angle can be read, improving the accuracy of the measurement azimuth.

[0034] according to Figure 1 , Figure 4 and Figure 5As shown, the instrument mounting and adjustment structure 9 is located on the upper end of the drive control module 6 and is a key structure for fixing and adjusting the elevation measuring instrument main unit 8. It includes an instrument mounting plate 91, an instrument clamping seat 92, a mounting and adjustment fixing hook 93, a hook pull ring 94, a mounting and adjustment reset spring 95, and a rotation adjustment shaft 96. The instrument mounting plate 91 is located in the center of the upper end of the drive control module 6, and the rotation adjustment shaft 96 is fixedly connected to its lower surface. The lower end of the rotation adjustment shaft 96 extends through a through hole in the upper end of the drive control module 6 to its internal bottom surface. The upper surface is equipped with measuring instrument clamping seats 92 on all four sides. The internally fitted mounting and fixing hook 93 extends to the outer end and is connected to the hook body pull ring 94. The outer end of the mounting and fixing hook 93 is fitted with a mounting and adjusting return spring 95 inside the measuring instrument clamping seat 92. Through the cooperation of the mounting and fixing hook 93 and the mounting and adjusting return spring 95, the measuring instrument clamping plate 71 of the measuring instrument protective box 7 can be quickly locked, realizing the convenient installation and fixing of the elevation measuring instrument main unit 8. At the same time, it can be adjusted in azimuth with the azimuth rotation mechanism 11 in conjunction with the rotating adjustment shaft 96.

[0035] according to Figure 1 and Figure 6 As shown, the instrument protective box 7 is movably installed on the upper end of the instrument assembly and adjustment structure 9 to accommodate and protect the elevation measuring instrument main unit 8. An instrument clamping plate 71 is fixedly connected to its lower surface. The outer edges of the instrument clamping plate 71 are movably clamped to the upper ends of four instrument holders 92, achieving a stable connection with the instrument assembly and adjustment structure 9. An observation window 72 is provided on the front surface of the instrument protective box 7 to facilitate observation and operation of the internal elevation measuring instrument main unit 8 by the operator. An instrument mounting slot 74 is provided in the center of the interior for placing the elevation measuring instrument main unit 8. A protective cover 73 is folded and connected to one side of the upper end, which can protect the main unit 8 of the elevation measuring instrument from dust and collision. The inner wall of the measuring instrument mounting slot 74 is provided with measuring instrument positioning plates 75 on both sides. The outer end surface is tightly attached to the two sides of the surface of the main unit 8 of the elevation measuring instrument. The measuring instrument limiting spring pads 76 are fixedly connected to both ends of the inner side surface of the measuring instrument positioning plate 75, and the other end is connected to the two sides of the inner wall of the measuring instrument mounting slot 74. Through the cooperation of the measuring instrument positioning plate 75 and the measuring instrument limiting spring pads 76, the main unit 8 of the elevation measuring instrument can be firmly clamped, preventing it from shaking during the measurement process.

[0036] The overall effect achieved by the organization is as follows:

[0037] The casters 15 at the bottom of the equipment base 1 enable convenient movement across complex terrains. Upon reaching the measurement point, rotating the screw on the base support block 11 and the handle 13 rotates the support adjustment screw 12, causing the anti-slip grounding pad 14 to contact the ground and adjust its height. Adjusting the four support adjustment screws 12 compensates for uneven ground, stabilizing the equipment base 1 and lifting the casters 15 off the ground, providing a stable foundation. Elevation adjustment is achieved through the cooperation of the elevation lifting mechanism 3 and the main support column 2. The elevation screw 22 inside the main support column 2 forms a threaded transmission with the threaded hole of the lifting guide column 31. The lifting drive motor 33 starts, driving the elevation screw 22 to rotate. Because the lifting guide column 31 is limited by the main support column 2, it... The rotation of the screw drive is converted into its vertical linear motion, which in turn causes the L-shaped measuring tool support plate 32 to drive the instrument assembly plate 4 to rise and fall. The measuring tool bearing plate 34 provides auxiliary support to improve stability. The column buffer pad 21 provides buffer protection when it rises to the highest position. The height of the elevation measuring instrument host 8 can be adjusted by controlling the forward and reverse rotation of the motor and the running time to adapt to different needs. The gravity leveling mechanism 10 uses the characteristics of gravity to achieve horizontal calibration. The ball joint seat 102 at the lower end of the leveling bracket 101 forms a spherical movable connection with the gravity main ball 103. The gravity auxiliary ball 105, connected to the gravity main ball 103 through the balance link 104, fits against the inner wall of the spherical balance track 106. When the equipment tilts, the gravity main ball 103... The dynamic gravity auxiliary ball 105 rolls along the track until the gravity main ball and balance rod are aligned with the direction of gravity, restoring the instrument mounting plate 4 and its upper components to a horizontal position and ensuring the accuracy of the measurement reference. Azimuth adjustment is achieved through the cooperation of the azimuth rotation mechanism 11 and the instrument mounting structure 9. The instrument mounting plate 91 is connected to the drive control module 6 via a rotation adjustment shaft 96. The rotation gear ring 111 at the lower end of the rotation adjustment shaft 96 meshes with the transmission worm gear 113 on the azimuth drive rod 112. Rotating the azimuth adjustment plate 114 drives the azimuth drive rod 112 and the transmission worm gear 113 to rotate, which in turn drives the rotation gear ring 111 and the rotation adjustment shaft 96 to rotate, achieving horizontal azimuth rotation of the instrument mounting plate 91 and its upper components. The needle 115 works in conjunction with the angle measuring gauge 61 to accurately read the angle, ensuring the accuracy of azimuth adjustment. The instrument mounting and adjusting structure 9 and the instrument protective box 7 enable the instrument to be quickly fixed and protected. The instrument clamping plate 71 is inserted into the instrument clamping seat 92. The mounting and adjusting fixing hook 93 is fastened to the clamping plate under the action of the mounting and adjusting reset spring 95. The hook body pull ring 94 can be pulled to remove it. The instrument embedding slot 74 in the instrument protective box 7 holds the main unit. The instrument positioning plate 75 is attached to both sides of the main unit to prevent shaking under the action of the instrument limiting spring pad 76. The protective box cover 73 is dustproof and collision-proof. The observation window 72 facilitates surveying. The whole system improves the efficiency and accuracy of mine elevation measurement by combining a continuous workflow with mechanical structure, gravity principle and transmission technology.
