Description

Technical Field

[0001] This invention relates to the field of underground installation equipment technology, and in particular to an intrinsically safe monitoring substation installation structure for mining applications. Background Technology

[0002] Substations used in coal mine roadways are typically installed in well-supported, leak-free, and debris-free intake roadways or chambers, where personnel can easily observe, debug, and inspect them. During installation, the substation needs to be continuously lifted before being secured underground using expansion bolts, a time-consuming and labor-intensive process. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems: The installation efficiency of monitoring substations is low.

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

The hanger is embedded in the mounting base through the installation groove. The guide groove is connected to the installation groove. The first end of the hanger is sized to match the width of the installation groove. The second end of the hanger is connected to the monitoring substation.

[0006] The present invention has the advantages and technical effects of fast and efficient installation and low manpower burden.

[0007] In some embodiments, the first end of the hanger has an arcuate surface to reduce the friction between the hanger and the guide groove.

[0008] In some embodiments, the extension direction of the guide groove is perpendicular to the extension direction of the mounting groove, the guide groove extends horizontally, and the mounting groove extends vertically.

[0009] In some embodiments, a locking mechanism is further included, the locking mechanism including a locking pin and a positioning hole, the positioning hole being arranged on the bracket, and a pin hole being provided on the bracket corresponding to the positioning hole, the locking pin passing through the positioning hole and entering the pin hole.

[0010] In some embodiments, the device further includes an anti-detachment protrusion, and the pendant is provided with a receiving cavity. At least a portion of the anti-detachment protrusion is pivotally arranged within the receiving cavity. The two ends of a compression spring are respectively connected to the anti-detachment protrusion and the inner wall of the receiving cavity to push the anti-detachment protrusion out of the receiving cavity.

[0011] In some embodiments, the mounting groove is a trapezoidal groove, and the width of the hanger gradually increases from the first end to the second end of the hanger.

[0012] In some embodiments, the width of the guide groove opening is greater than the width of the groove bottom, and the cross-section of the guide groove is an inverted trapezoid.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] An embodiment of the present invention proposes an installation structure for an intrinsically safe monitoring substation 3 in a mine, including a mounting base 1 and a hanging component 2. The mounting base 1 is fixed to the side wall of the roadway through an installation foundation. The mounting base 1 is provided with an installation groove 101 and a guide groove 102. The hanging component 2 is embedded into the mounting base 1 through the installation groove 101. The guide groove 102 is connected to the installation groove 101. The first end of the hanging component 2 is sized to match the width of the installation groove 101. The second end of the hanging component 2 is connected to the monitoring substation 3.

[0022] By placing the hanger 1 on an independent installation foundation and pre-fixing it to the side of the roadway, the high-intensity work of workers holding heavy objects for a long time for positioning and fixing is effectively avoided, significantly reducing labor costs and improving operational safety. The connection design between the guide groove 102 and the installation groove 101 establishes an installation sequence of guiding first and then locking. Using the guide groove 102 as a highly tolerant initial alignment entry point, it can assist workers in quickly blindly aligning the device in dim lighting or obstructed visibility underground, thus guiding the hanger 2 to slide into the installation groove 101. With the matching width of the first end of the hanger 2 and the installation groove 101, not only is a stable gravity self-locking achieved using the weight of the substation, but the lateral sway of the equipment is also limited by the installation groove 101. This ensures the stability of the equipment installation in harsh underground environments while greatly improving the operability and convenience of on-site assembly. The hanger 2 can be an L-shaped workpiece, formed by splicing two mutually perpendicular connecting sections. The first connecting section enters the installation groove 101 of the hanger 1, while the second connecting section extends horizontally and connects to the monitoring substation 3.

[0023] In some embodiments, the first end of the hanger 2 has an arc-shaped surface to reduce the friction between the hanger 2 and the guide groove 102.

[0024] Specifically, the curved surface transforms the point or line contact between the hanger 2 and the guide groove 102 into a surface contact, dispersing contact pressure and significantly reducing the coefficient of friction. This allows the hanger 2 to slide more smoothly within the guide groove 102, greatly reducing operational resistance during installation or disassembly in confined underground spaces, improving work efficiency, and reducing manual labor intensity. The curved surface avoids localized stress concentration caused by sharp edges and corners, reducing structural fatigue damage caused by frequent underground vibrations and extending the service life of the hanger 2 and the mounting base 1. Furthermore, the curved surface does not easily accumulate dust, slag, or other impurities, preventing jamming caused by impurity buildup, ensuring the stability of the installation structure, and fitting the harsh, dusty environment of underground mines.

[0025] In some embodiments, the extension direction of the guide groove 102 is perpendicular to the extension direction of the mounting groove 101, the guide groove 102 extends in a horizontal direction, and the mounting groove 101 extends in a vertical direction.

[0026] Specifically, the horizontal guide groove 102 conforms to the natural movement habits of personnel standing during operation, allowing the hanger 2 to be smoothly pushed into the guide groove 102 in the horizontal direction without the need for significant lifting or flipping, thus significantly reducing the difficulty of installation operations in confined underground spaces. The vertical installation groove 101 is aligned with the direction of gravity, and after the hanger 2 is embedded, the gravity is directly borne by the installation groove 101, avoiding structural movement caused by lateral forces. The size matching between the hanger 2 and the installation groove 101 further enhances the overall installation stability and adapts to the high-frequency vibration conditions in mines. The guide groove 102 and the installation groove 101 achieve the separation of guiding and positioning functions from load-bearing and fixing functions. The guide groove 102 accurately guides the hanger 2 into place, while the vertical installation groove 101 provides reliable load-bearing, greatly improving installation accuracy and reducing structural wear caused by installation deviations.

[0027] In some embodiments, a locking mechanism is also included, which includes a locking pin and a positioning hole. The positioning hole is arranged on the bracket 1, and a pin hole is provided on the bracket 2 corresponding to the positioning hole. The locking pin passes through the positioning hole and enters the pin hole.

[0028] Specifically, the locking pin penetrates the double nesting of the positioning hole of the bracket 1 and the pin hole of the hanger 2, forming an axial rigid constraint. This effectively resists the lateral / longitudinal impact forces caused by the operation of underground equipment, roadway vibration, and personnel collisions, preventing the hanger 2 from moving or falling off along the mounting groove 101 and guide groove 102, and providing fixation for the monitoring substation 3. The holes of the bracket 1 and the hanger 2 are set in correspondence, so workers can determine whether the hanger 2 is installed in place without complicated calibration. Combined with the insertion and removal operation of the locking pin, the installation / disassembly time in the confined space underground is greatly shortened. The rigid locking can eliminate the intermittent friction between the hanger 2 and the bracket 1, reduce hole wear and structural fatigue caused by long-term vibration, and extend the service life of the overall installation structure.

[0029] In some embodiments, the device further includes an anti-detachment boss 201, and a receiving cavity is provided on the hanger 2. At least part of the anti-detachment boss 201 is pivotally arranged in the receiving cavity. The two ends of the compression spring are respectively connected to the anti-detachment boss 201 and the inner wall of the receiving cavity to push the anti-detachment boss 201 out of the receiving cavity.

[0030] Specifically, the anti-detachment boss 201 always maintains a tendency to protrude out of the receiving cavity under the action of the compression spring. When the hanger 2 is pushed into the guide groove 102 and embedded in the installation groove 101, the anti-detachment boss 201 will automatically pop out and form a mechanical engagement with the inner wall of the hanger 1 or the preset limiting surface. The preset limiting surface can be the lower surface of the hanger 1. At this time, the anti-detachment boss 201 abuts against the lower surface of the hanger 1, and the anti-detachment locking can be achieved without additional manual operation, which greatly improves the convenience of installation. Even if the locking pin is accidentally loosened, the anti-detachment boss 201 can still prevent the hanger 2 from falling off, which significantly improves the structural safety. The pivotable design of the anti-detachment boss 201 allows it to overcome the spring force and retract into the receiving cavity by the squeezing force of the inner wall of the hanger 1 when the hanger 2 is installed or removed, avoiding obstruction to the installation / removal process. Moreover, compared with the fixed boss, the pivot structure can reduce contact wear and extend the service life. The continuous preload of the compression spring ensures that the engagement surface of the anti-derailment boss 201 and the mounting bracket 1 remains tightly fitted, effectively resisting the impact of high-frequency vibrations downhole, preventing the boss from developing gaps or accidentally retracting due to vibration, and ensuring the stability and reliability of the anti-derailment function. The anti-derailment boss 201 can be manually pressed into the receiving cavity for manual unlocking.

[0031] In some embodiments, the mounting groove 101 is a trapezoidal groove, and the width of the hanger 2 gradually increases from the first end to the second end of the hanger 2.

[0032] Specifically, the wide-mouth, narrow-bottom structure of the trapezoidal groove, combined with the gradually changing width design of the hanger 2, forms a wedge-shaped fit. This effectively disperses the load generated by the self-weight and vibration of the monitoring substation 3, preventing structural deformation or wear caused by localized stress concentration. After the hanger 2 is embedded, the self-locking effect created by the gradually changing width, along with gravity, effectively resists the lateral force generated by the operation of underground equipment and roadway vibration, preventing the hanger 2 from detaching from the mounting slot 101 and significantly improving the anti-loosening stability of the installation structure. At the same time, the wedge-shaped mating surface increases the contact area between the hanger 2 and the mounting slot 101, reducing the pressure per unit area. The tight fit reduces gap friction caused by vibration, extending the service life of the components. Furthermore, the guide slope of the trapezoidal groove is consistent with the gradually changing width trend of the hanger 2, guiding the hanger 2 to automatically center and embed during installation without the need for precise calibration, reducing the difficulty of installation operations in confined underground spaces.

[0033] In some embodiments, the width of the guide groove 102 opening is greater than the width of the groove bottom, and the cross-section of the guide groove 102 is an inverted trapezoid.

[0034] Specifically, the structure with a slot width greater than the slot bottom significantly reduces the difficulty of aligning the hanger 2 during insertion. Even in environments with poor visibility and limited operating space underground, the hanger 2 can be quickly guided into the slot, improving installation efficiency. The two inclined sides of the inverted trapezoid form a natural guide channel. After the hanger 2 enters the slot, it will automatically slide towards the bottom of the slot along the inclined side to center itself, eliminating the need for manual calibration and ensuring precise alignment between the hanger 2 and the installation slot 101, reducing installation deviation. The two inclined sides form a surface contact with the hanger 2, which, compared to a flat contact, can disperse the lateral force generated by vibration, effectively suppressing the lateral movement of the hanger 2 within the slot. Combined with the locking mechanism and the anti-detachment protrusion 201, this further enhances the stability of the structure under high-frequency vibration environments. At the same time, the inverted trapezoidal structure prevents dust from accumulating in the slot. Coal dust and rock powder will naturally slide down along the inclined side, preventing impurities from getting stuck and affecting the sliding of the hanger 2. This is suitable for the harsh environment of dusty mines and extends the service life of the structure.

[0035] Optionally, a dust discharge hole is provided at the bottom of the guide groove 102 to discharge dust and impurities. Multiple dust guide grooves are provided along the inclined surface of the guide groove 102, which, together with the dust discharge hole at the bottom of the groove, quickly export the dust brought in during the embedding process.

[0036] In some embodiments, a limiting block is also included, which is arranged at the junction of the guide groove 102 and the mounting groove 101, and the limiting block protrudes to block the hanging piece 2.

[0037] Specifically, the limiting block provides a clear mechanical limit to the sliding stroke of the hanger 2. When the hanger 2 is pushed into the guide groove 102 to the junction, the limiting block accurately indicates the position of the hanger 2, allowing the operator to feel the resistance and continue moving, directly marking the installation position. This avoids over-positioning or installation deviation of the hanger 2 due to poor downhole visibility or limited operating space, ensuring that the pin hole of the hanger 2 and the positioning hole of the bracket 1 are quickly and accurately aligned. The limiting block can disperse the impact force when the hanger 2 is inserted, preventing rigid collision between the hanger 2 and the inner wall of the installation groove 101, reducing the risk of structural wear and deformation, and extending the service life of the hanger 2 and the bracket 1. In a high-frequency vibration environment, the limiting block can withstand the lateral impact force of the hanger 2, inhibiting the movement of the hanger 2 and improving the stability and reliability of the overall installation structure. The limiting block can be made of oil-resistant rubber to prevent rigid collision when the hanger 2 is pushed in, while also forming a pre-positioning.

[0038] In some embodiments, a leveling mechanism is also included, which includes a level, adjusting nuts, and adjusting screws. The adjusting screws are arranged at the four corners of the mounting base and pass through the mounting base to connect with the sidewall of the roadway. Two adjusting nuts are arranged on the adjusting screws and clamp the mounting base. The level is arranged at the top of the mounting base.

[0039] Specifically, the level is positioned at the top of the installation foundation, providing real-time and intuitive feedback on its horizontal status. This avoids blind leveling when visibility is poor or precise measuring tools are lacking underground, allowing workers to quickly determine the adjustment direction. The four corner adjustment screws, combined with the double adjustment nuts clamping the installation foundation, enable two-dimensional fine leveling in the vertical, horizontal, and front-back directions. By rotating the adjustment nuts, the height of each corner of the installation foundation can be changed, easily correcting tilt errors caused by uneven sidewalls. This ensures that the horizontal error of the installation foundation is within acceptable limits, thereby guaranteeing that the monitoring components (such as cameras and sensors) of monitoring substation 3 are in a horizontal working state, avoiding monitoring data deviations caused by tilting. The locking method of the double adjustment nuts clamping the installation foundation forms a two-way anti-loosening constraint, effectively resisting the risk of nut loosening caused by high-frequency vibrations underground. Combined with the stable connection between the adjustment screws and the roadway sidewall, this ensures that the installation foundation remains horizontally stable for a long time after leveling, eliminating the need for frequent re-inspection and adjustment.

[0040] In some embodiments, a buffer and shock-absorbing layer is also included, which is disposed on the inner wall of the mounting groove 101 or on the contact surface between the hanger 2 and the mounting groove 101.

[0041] Specifically, the buffer and damping layer effectively absorbs the vibration energy generated by tunnel blasting, tunneling operations, and equipment operation, attenuating the vibration amplitude transmitted to monitoring substation 3. This prevents damage or poor contact of precision components such as sensors and circuit boards inside the substation due to vibration, ensuring the continuity and accuracy of monitoring data. The elastic properties of the buffer and damping layer fill the gap between the hanger 2 and the mounting groove 101, eliminating rigid collisions and frictional noises caused by vibration, reducing wear on the contact surface between the hanger 2 and the mounting groove 101, improving the overall installation stability, and preventing structural loosening caused by long-term vibration. The buffer and damping layer can be made of oil-resistant and wear-resistant polyurethane or other materials. Other materials can be a composite structure of an elastic substrate and a wear-resistant surface layer. The elastic substrate can be rubber, and the wear-resistant surface layer can be reinforced with ceramic particles or a polytetrafluoroethylene layer.
