Description

Technical Field

[0001] This utility model relates to the field of mining protective equipment technology, and in particular to a mining protective shed. Background Technology

[0002] The inner walls of the auxiliary shafts in large coal mines often drip a lot of water. When miners descend into the mine in cages, this water drips down to the bottom. When the cage reaches the connection point between the shaft and the bottom yard (the gate), workers enter and exit the cage. However, because the shaft and gate are connected, the water dripping from the shaft's inner wall falls onto the workers, potentially causing rheumatism, arthritis, and other ailments. To prevent this water from dripping onto the workers, relevant technologies install protective canopies at the gates, extending at least partially into the shaft to block the water from dripping down the inner wall.

[0003] However, because the protective canopy extends at least partially into the shaft, the traditional canopy becomes a physical obstacle to transporting long materials (such as long-length materials or tools). To ensure the smooth entry and exit of long materials, workers have to frequently dismantle and install the protective canopy, or are forced to reduce the amount transported per trip. Regardless of the method used, this significantly increases labor intensity and reduces the efficiency of transporting long materials, becoming a bottleneck affecting the efficient operation of the mine. Utility Model Content

[0004] The main purpose of this utility model is to propose a mine protective shed, which aims to solve the problem that traditional protective sheds often become physical obstacles to the transportation of long materials, thus reducing the transportation efficiency of long materials.

[0005] To achieve the above objectives, the mine protective shed proposed in this utility model includes a guide, a shed body, and a driving device. The guide is disposed inside the gate and extends along the direction from the gate to the shaft. The shed body is slidably connected to the guide. The driving device is fixedly disposed inside the gate and is drively connected to the shed body. The driving device is configured to drive the shed body to move closer to or away from the shaft, so that the shed body extends at least partially into the shaft or is completely contained within the gate.

[0006] In one embodiment, the canopy includes an interconnected roof and a support, the support being slidably connected to the guide and drively connected to the drive device, and the roof forming a drainage surface extending along the top wall of the gate to the side wall of the gate.

[0007] In one embodiment, the mine protective shed further includes a water collection component and a drainage pipe. The water collection component is located inside the gate and forms a water collection trough. The opening of the water collection trough is positioned facing the edge of the water distribution surface. The drainage pipe is sealed and passes through the water collection component, and the inner cavity of the drainage pipe communicates with the water collection trough.

[0008] In one embodiment, at least two water-blocking members are also formed on the ceiling. The at least two water-blocking members are distributed along the extension direction of the guide member and connected to the water-diffusing surface. The two water-blocking members and the water-diffusing surface enclose a water-diffusing trough.

[0009] In one embodiment, the guide is a strip guide rail, and the canopy is provided with pulleys, which are tumblingly connected to the strip guide rail.

[0010] In one embodiment, the pulley is provided with an anti-detachment groove, the anti-detachment groove extends circumferentially along the pulley, and the strip guide rail extends into the anti-detachment groove and is confined between the opposite side walls of the anti-detachment groove.

[0011] In one embodiment, the mine protective shed further includes an input unit and a control unit, wherein the control unit is electrically or communicatively connected to the drive device, and the input unit is electrically or communicatively connected to the control unit.

[0012] In one embodiment, the mine protective shed further includes a position detection unit, which is electrically or communicatively connected to the control unit; the position detection unit is disposed at the end of the guide member closer to the shaft, and / or, the position detection unit is disposed at the end of the guide member farther from the shaft.

[0013] In one embodiment, the driving device is a servo motor, and the mining protective shed further includes a lead screw and a connecting block. The lead screw is coaxially connected to the output shaft of the servo motor, and the connecting block is fixedly connected to the shed body. The connecting block is sleeved on the lead screw and threadedly connected to the lead screw.

[0014] In one embodiment, the mine protective shed further includes at least two support members, which are spaced apart along the extension direction of the guide member and connected to the guide member. The support members are used to fix the mine protective shed inside the gate.

[0015] This utility model proposes a mine safety shed comprising a guide member, a shed body, and a driving device. The guide member is located inside the mine shaft entrance and extends along the direction from the entrance to the shaft. The shed body is slidably connected to the guide member. The driving device is fixedly located inside the mine shaft entrance and is drively connected to the shed body. The driving device is configured to drive the shed body to move closer to or further away from the shaft, so that the shed body is at least partially inserted into the shaft or completely contained within the mine shaft entrance. Thus, by driving the shed body to reciprocate along the guide member, the shed body can at least partially extend into the shaft or be completely contained within the mine shaft entrance. Therefore, when transporting long materials, the shed body can be temporarily retracted into the mine shaft entrance to avoid obstructing the transport of long materials. After the long materials are transported, the shed body can be immediately restored to its original position, so that at least partially extending into the shaft restores its protective function against water seepage from the shaft's inner wall. Therefore, this solves the problem that traditional mine safety sheds often become physical obstacles to the transport of long materials, thus reducing the efficiency of long material transport.

[0023] This utility model proposes a mine protective shed 100, which is applied to the mirror tube and horse head gate 200 of the auxiliary shaft of a coal mine.

[0024] Please see Figures 1 to 3 In one embodiment of the present invention, the mine protective shed 100 includes a guide 1, a shed body 2, and a driving device. The guide 1 is disposed inside the gate 200 and extends along the direction from the gate 200 to the shaft 300. The shed body 2 is slidably connected to the guide 1. The driving device is fixedly disposed inside the gate 200 and is connected to the shed body 2 in a transmission manner. The driving device is configured to drive the shed body 2 to move closer to or away from the shaft 300, so that the shed body 2 at least partially extends into the shaft 300 or is completely contained within the gate 200.

[0025] In this embodiment, the mine protective shed 100 is arranged in the area of ​​the auxiliary shaft gate 200 of the coal mine. When personnel are going up or down the cage, it extends into the shaft 300 to block water from splashing. When long materials pass through, it completely retracts below the top plate of the gate 200 to avoid interference with the long materials.

[0026] Specifically, the canopy 2 can adopt a truss structure. For example, the canopy 2 includes multiple metal trusses connected to form a frame. The top surface is connected to the roof 21 by rivets or self-tapping screws. The roof 21 can be made of corrugated plates or flat plates made of stainless steel or plastic. The joints of the plates are coated with sealant to form a continuous drainage surface 211. The drainage surface 211 is set in a planar or curved shape. The two sides of the roof 21 are bent downward to form a water-retaining eave.

[0027] The guide component 1 is used to guide and constrain the sliding direction of the canopy 2, ensuring that the canopy 2 remains stable and does not deviate from the predetermined trajectory during expansion and retraction. The guide component 1 can be a guide rail, a sliding rod, or a steel wire, etc. For example, when the guide component 1 uses a guide rail, the guide rail can be a rectangular hollow steel section, laid horizontally along the direction from the head gate 200 to the shaft 300. A groove extending along the guide rail is opened on the top wall of the guide rail, with the groove opening facing upwards. Rollers are arranged at corresponding positions on the bottom of the canopy 2, with vibration damping sleeves wrapped around the outer ring of the rollers, and the rollers are embedded in the grooves. The rollers move back and forth along the grooves to achieve smooth expansion and contraction of the canopy 2. When the guide component 1 uses a sliding rod, the sliding rod is made of round steel or steel pipe with a polished surface to reduce frictional resistance. Both ends of the sliding rod are fixed to the top or side wall of the gate 200 via supports, and its axis is parallel to the direction of movement of the canopy 2. A sliding sleeve is installed at the top or bottom of the canopy 2, covering the outer circumference of the sliding rod. The sliding sleeve is connected to the frame of the canopy 2 via bolts or welding. When the canopy 2 slides, the sliding sleeve slides along the axial direction of the sliding rod. The sliding rod and the sliding sleeve cooperate to provide radial constraint for the canopy 2, preventing it from swaying. When the guide component 1 uses steel wire, the steel wire is made of galvanized multi-strand steel wire rope, with both ends anchored to the side wall of the gate 200 via fasteners. After tensioning, the steel wire forms a straight tension line. A lifting ring is installed at the top of the canopy 2, with a wear-resistant engineering plastic sliding sleeve inserted inside. The sliding sleeve encircles the steel wire. When the canopy 2 moves, the sliding sleeve slides along the steel wire. The steel wire provides lateral positioning and allows the canopy 2 to slide longitudinally, making it suitable for situations where space is limited and rigid tracks are inconvenient to install.

[0028] The drive unit provides power for the reciprocating motion of the canopy 2, switching it between extended and retracted positions. The drive unit can be a servo motor 3, a cylinder, or a linear motor, and has remote control functionality, allowing operators to control it remotely from a surface control room or a safe area underground. For example, when the drive unit uses a servo motor 3, the servo motor 3 and the reducer are integrated and mounted on the side or top wall of the canopy 200. The output shaft is connected to a double-row roller sprocket, one end of the chain is fixed to the front end of the canopy 2, and the other end passes over the driven sprocket and suspends a counterweight. When the drive unit uses a cylinder, the cylinder body is mounted on the side or top wall of the canopy 200, and the front end of the piston rod is connected to the middle of the canopy 2 via a ball joint. The air source comes from the underground compressed air pipeline and is controlled by a solenoid valve. After receiving a remote control signal, the solenoid valve switches the air path, the piston rod extends to push the canopy 2 forward, and the piston rod retracts to pull the canopy 2 back to its original position.

[0029] In summary, this embodiment uses a driving device to drive the canopy 2 to reciprocate along the guide member 1, allowing the canopy 2 to extend at least partially into the shaft 300 or be completely contained within the gate 200. Thus, when transporting long materials, the canopy 2 can be temporarily retracted into the gate 200 to prevent it from obstructing the transport of long materials. After the long materials are transported, the canopy 2 can be immediately restored to its original position, allowing it to extend at least partially into the shaft 300 to restore its protective function against water seepage from the inner wall of the shaft 300. Therefore, this solves the problem that traditional mine protective canopies 100 often become physical obstacles to the transport of long materials, thus reducing the efficiency of long material transport.

[0030] Further, please refer to Figure 2 , Figure 3 and Figure 6 In one embodiment of the present invention, the canopy 2 includes a canopy 21 and a support 22 connected to each other. The support 22 is slidably connected to the guide member 1 and is connected to the drive device. The canopy 21 forms a drainage surface 211 extending along the top wall of the gate 200 to the side wall of the gate 200.

[0031] In this embodiment, the canopy 2 includes an interconnected roof 21 and a support 22. The support 22 is slidably connected to the guide member 1 and is driven by the drive device. The roof 21 forms a drainage surface 211 extending from the top wall of the gate 200 to the side wall of the gate 200. That is, the roof 21 can be a pointed roof, a sloping roof, an arched roof, etc. The drainage surface 211 is continuous and has a highest point and a lowest point. The water flows from the highest point to the lowest point and is quickly discharged along the drainage surface 211 to the drainage ditch on the side wall of the gate 200 or to a device for collecting water, avoiding stagnation on the roof. When the roof 21 is a pointed roof, the ridge is parallel to the passage direction of the gate 200, and the two sloping sides are symmetrically arranged. The included angle is determined comprehensively based on the water spray intensity of the well 300 and the width of the canopy 2. This embodiment does not limit this. The roof 21 can also be a unidirectional sloping roof or an arched roof. Both can accelerate the drainage speed of the roof 21 and prevent rainwater accumulation from increasing the load on the canopy 2.

[0032] Further, please refer to Figure 2 and Figure 4 In one embodiment of this utility model, the mine protective shed 100 further includes a water collection component 4 and a drain pipe 5. The water collection component 4 is located inside the gate 200 and forms a water collection trough 4a. The opening of the water collection trough 4a is set towards the edge of the water distribution surface 211. The drain pipe 5 is sealed and passes through the water collection component 4. The inner cavity of the drain pipe 5 is connected to the water collection trough 4a.

[0033] In this embodiment, the water collection component 4 can be made of rust-resistant stainless steel plate bent into a U-shape or C-shape long trough. The trough extends horizontally along the side wall of the gate 200, covering the edge of the lowest point of the entire water distribution surface 211 within the movement range of the shed body 2. The trough opening faces upward and is directly or indirectly connected to the side wall of the gate 200. The bottom of the trough can be provided with a horizontal and / or longitudinal slope. The drain pipe 5 can be made of corrosion-resistant metal pipes such as stainless steel or plastic pipes. One end of the drain pipe 5 passes through the bottom wall or side wall of the water collection trough 4a, and the pipe opening of the drain pipe 5 is located at the lowest point of the water collection trough 4a. The other end of the drain pipe 5 runs down along the side wall of the gate 200 to the bottom water ditch, directly introducing the water into the mine drainage system to keep the area of ​​the gate 200 dry. The edge of the water-spreading surface 211 is located directly above the water collection trough 4a, with a safe gap between them to ensure that the reciprocating movement of the canopy 2 is not interfered with. At the same time, the gap width is less than the distance that water splashes out when it slides down, preventing water from being unable to fall into the water collection trough 4a after it splashes out of the water-spreading surface 211 of the canopy 21. The water is collected in time by the water collection trough 4a and quickly drained by the drain pipe 5, so that the water no longer flows randomly along the side wall, preventing water accumulation in the interior of the gable door 200 and damp walls from affecting underground work, and protecting the underground electromechanical equipment from dripping water corrosion.

[0034] Further, please refer to Figure 1 and Figure 7In one embodiment of the present invention, at least two water-blocking members 212 are also formed on the canopy 21. The at least two water-blocking members 212 are distributed along the extension direction of the guide member 1 and connected to the water-spreading surface 211. The two water-blocking members 212 and the water-spreading surface 211 enclose each other to form a water-spreading trough 21a.

[0035] In this embodiment, the water-blocking component 212 can be integrally formed with the roof 21, and the cross-section of the connection between the water-blocking component 212 and the roof 21 is inverted L-shaped. Alternatively, a split water-blocking component 212 can be used, in which case the water-blocking component 212 can be rib-shaped or L-shaped, and the vertical edge of the water-blocking component 212 is fully welded to the water-draining surface 211. The water-blocking component 212 extends along the direction perpendicular to the sliding of the roof body 2, and each water-blocking component 212 is arranged at intervals along the sliding direction of the roof body 2, with the spacing determined according to the total length of the roof body 2. However, at least two water-blocking components 212 need to be installed. One water-blocking component 212 is located at the end of the roof 21 near the well shaft 300, and the other water-blocking component 212 is located at the end of the roof 21 away from the well shaft 300. This prevents water from flowing into the depth of the gate 200 or into the well shaft 300. That is, under the constraint of the water-blocking component 212, the water can only flow into the drainage channel or water collection trough 4a on the side of the gate 200, so as to prevent the staff inside the gate 200 and the staff inside the cage of the well shaft 300 from getting wet.

[0036] Further, please refer to Figure 4 and Figure 7 In one embodiment of this utility model, the guide 1 is a strip guide rail, and the canopy 2 is provided with a pulley 23, which is tumblingly connected to the strip guide rail.

[0037] In this embodiment, the strip guide rail can be made of hollow steel or I-beams, extending horizontally along the direction from the gate 200 to the shaft 300. A pulley 23 is located at the bottom of the support 22 of the shed body 2. A wheel seat is connected to the bottom of the support 22 by welding or bolting, and the pulley 23 is rotatably connected to the wheel seat via a rotating shaft. In this embodiment, the rolling contact between the pulley 23 and the strip guide rail significantly reduces the sliding resistance and wear of the shed body 2. Manual operation requires only one person to push it. When driven by a motor or cylinder, the movement is smooth and quiet, and the system has high reliability, meeting the requirements for frequent start-stop operations.

[0038] Further, please refer to Figure 4 In one embodiment of the present invention, the pulley 23 is provided with an anti-detachment groove 23a, which extends circumferentially along the pulley 23. The strip guide rail extends into the anti-detachment groove 23a and is confined between the opposite side walls of the anti-detachment groove 23a.

[0039] In this embodiment, an annular anti-detachment groove 23a is machined on the outer periphery of the pulley 23. That is, the anti-detachment groove 23a extends continuously along the circumference of the pulley 23, and its width matches the width of the strip guide rail. The lower end of the strip guide rail is embedded in the anti-detachment groove 23a, and the two side walls of the groove form a lateral clamping effect on the guide rail, limiting the left-right swaying of the pulley 23 relative to the guide rail and maintaining smooth rolling. The bottom surface of the anti-detachment groove 23a is an arc surface, making rolling contact with the guide rail, reducing friction, ensuring smooth movement of the shed 2 and reducing friction between the pulley 23 and the strip guide rail. The side wall of the anti-detachment groove 23a maintains a slight gap with the guide rail, ensuring the stability of the sliding of the shed 2 and preventing jamming due to skew. In this embodiment, by setting the anti-detachment groove 23a on the pulley 23 and allowing the strip guide rail to extend into the anti-detachment groove 23a and be confined between the opposite side walls of the anti-detachment groove 23a, it is ensured that the pulley 23 always rolls along the strip guide rail and will not detach from it.

[0040] Furthermore, in one embodiment of this utility model, the mine protective shed 100 also includes an input unit and a control unit, the control unit being electrically or communicatively connected to the drive device, and the input unit being electrically or communicatively connected to the control unit.

[0041] In this embodiment, the control unit can be a microprocessor, a programmable logic controller, or other devices with logic operation and output control functions. The input unit can be a physical button, a touchscreen of a mobile device such as a mobile phone or tablet, or a device capable of signal input such as a wireless remote control. For example, when the drive device is a servo motor 3, signals to make the servo motor 3 rotate forward, reverse, or stop can be input. When the drive device is a cylinder, signals to make the cylinder piston extend, retract, or stop can be input. When the input unit uses a physical button, the signal line is directly connected to the digital input port of the control unit; when the input unit uses a mobile device such as a mobile phone or tablet or a remote control, it communicates with the control unit via underground WiFi or Bluetooth. The control unit is configured to respond to operation commands from the input unit and control the drive device to perform actions such as starting and stopping.

[0042] Furthermore, in one embodiment of this utility model, the mine protective shed 100 further includes a position detection unit, which is electrically or communicatively connected to the control unit; the position detection unit is provided at the end of the guide member 1 that is close to the shaft 300, and / or, the position detection unit is provided at the end of the guide member 1 that is far away from the shaft 300.

[0043] In this embodiment, based on the previous embodiment, the mine protective shed 100 is further equipped with a position detection unit, which is electrically connected to the control unit. This unit is used to detect the extreme positions of the shed body 2 and generate a position signal. The control unit is configured to: respond to an operation command from the input unit, control the drive device to start, and control the drive device to stop operating when it receives a position signal from the position detection unit indicating that the shed body 2 has reached a predetermined position.

[0044] The position detection unit can be a photoelectric gate or a pressure sensor, etc. The position detection unit is located at the end of the guide member 1 closest to the well shaft 300, and / or at the end of the guide member 1 furthest from the well shaft 300. At the end closest to the well shaft 300, when the position detection unit is triggered, it ensures that the distance the front end of the canopy 2 extends into the well shaft 300 meets the water-blocking requirements and does not collide with the cage track; at the end furthest from the well shaft 300, when the position detection unit is triggered, it ensures that the canopy 2 is completely retracted into the gable gate 200.

[0045] Further, please refer to Figure 5 , Figure 7 and Figure 8 In one embodiment of this utility model, the driving device is a servo motor 3, and the mine protective shed 100 also includes a lead screw 61 and a connecting block 62. The lead screw 61 is coaxially connected to the output shaft of the servo motor 3, and the connecting block 62 is fixedly connected to the shed body 2. The connecting block 62 is sleeved on the lead screw 61 and threadedly connected to the lead screw 61.

[0046] In this embodiment, a steel beam can be fixed to the side wall of the gate 200, and the servo motor 3 is fixed to the steel beam. To avoid affecting the sliding of the canopy 2, a certain gap is reserved between the steel beam and the canopy 2. Therefore, a heightening block can be set on the steel beam, and the servo motor 3 is set on the heightening block to ensure that the position of the servo motor 3 can be aligned with the connecting block 62 on the canopy 2 without interfering with the sliding of the canopy 2. In order to reduce the wear of the lead screw 61 and the connecting block 62, the lead screw 61 can be a ball screw 61, and the connecting block 62 is a ball nut. Lithium-based grease is injected regularly to keep the threaded pair lubricated for a long time and extend its service life. Through the threaded transmission cooperation of the servo motor 3, the lead screw 61 and the connecting block 62, the canopy 2 runs smoothly with low noise and has a power-off self-locking function, which is particularly suitable for mine water spray protection occasions that require frequent start-stop and precise positioning.

[0047] Further, please refer to Figure 2 and Figure 6 In one embodiment of the present invention, the mine protective shed 100 further includes at least two support members 7, which are spaced apart along the extension direction of the guide member 1 and connected to the guide member 1. The support members 7 are used to fix the shed inside the gate 200.

[0048] In this embodiment, based on the above embodiments, the mine protective shed 100 further includes at least two support members 7, such as... Figure 2 As shown, to maintain stability, a guide member 1 is provided on each side of the gable gate 200. Correspondingly, at least one support member 7 needs to be provided on each side wall of the gable gate 200, with a guide member 1 fixedly placed on each support member 7. It is necessary to ensure that each support member 7 has sufficient length to support the strip-shaped guide member 1. For ease of installation and production, multiple miniaturized support members 7 can be provided on each side to replace the large support member 7 extending along the guide member 1. Regardless of whether two or more support members 7 are used, this embodiment adds support members 7 and pre-installs them on the side wall of the gable gate 200 before installing the guide member 1. This provides a certain support base for adjusting the horizontal position of the guide member 1, making adjustment more convenient. Furthermore, when the guide member 1 wears down after long-term use and needs to be replaced, a new guide member 1 can be installed on the original support member 7 without significant adjustment of the new guide member 1's position, facilitating maintenance.

[0049] For example, please refer to Figure 2 and Figure 3 The support member 7 has a support surface and a mounting surface arranged at an angle. The mounting surface has openings for inserting anchor rods or bolts to connect to the side wall of the gate 200. The support surface and the mounting surface are arranged at an angle and are horizontal or nearly horizontal. The support surface is used to support the guide member 1, and the water collection member 4 can also be placed on the support member 7 and arranged parallel to the guide member 1. A steel beam for installing the drive device can also be arranged laterally, with both ends of the steel beam connected to the support members 7 on both sides of the gate 200.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
