Description

Technical Field

[0001] This invention relates to the field of mine construction technology, specifically to a safety device for the construction of the casing wall of a mining vertical shaft. Background Technology

[0002] During the construction of mining shafts, the casing construction is a key process to ensure the stability of the shaft structure. The construction requires a series of operations such as formwork erection and concrete pouring inside the deep shaft. The working environment is characterized by high altitude, proximity to edges, enclosed space, and uneven inner walls of the shaft, which poses many safety hazards.

[0003] In current shaft wall construction, simple suspended cages are commonly used as working platforms, which have the following drawbacks: First, the working platform lacks effective protection against falls and falling objects from above. During construction, falling debris such as gravel and tools from above the shaft can easily injure workers underground. Furthermore, if the platform itself fails to suspend, it is highly likely to experience a complete collapse. Second, the working platform has poor positioning stability within the shaft. It is prone to swaying and tilting due to airflow and disturbances during construction operations, which not only affects construction accuracy but also increases the risk of workers falling. To address the problems in the existing technology, there is an urgent need to design a safety device for shaft wall construction in mining vertical shafts that integrates fall prevention, falling object prevention, and stable positioning to solve the safety hazards of the current construction method and improve the overall safety and efficiency of shaft wall construction. Summary of the Invention

The end of the positioning pusher away from the center of the suspended shell is provided with teeth, and the lower surface of the end near the center of the suspended shell is provided with a sliding groove. The sliding groove is in sliding contact with the pushing disc. A drive motor is provided inside the suspended roof, and the output end of the drive motor is fixedly connected to the center of the pushing disc.

[0013] Preferably, the pushing plate is disposed inside the suspension shell, and the upper surface of the pushing plate is provided with an annular wave-shaped slide rail, which cooperates with the slide groove of the positioning pusher.

[0014] Preferably, the wall-mounted construction chamber includes a support frame, a protective rod, and a construction ladder assembly. The lower end of the support frame is a support plate, and the upper end is a support rod. The top of the support rod is fixedly connected to the suspended shell. The protective rod is set at the edge of the support frame for support and protection. The construction ladder assembly includes upper and lower sets of rails and a climbing ladder. The upper and lower sets of rails are respectively set on the surfaces of the suspended shell and the support frame.

The surface of the positioning slider is slidably connected to the bottom surface of the support frame, and an anti-slip surface is provided on the end face of the positioning slider. The folding rod of the lifting system is hinged to the positioning slider.

[0016] Preferably, the fall protection mechanism includes an actuating wheel and an embedded lever.

The embedded lever is a bent flat plate disposed on the outside of the actuating wheel and is fixedly connected to the actuating wheel. A notch is provided on the outer circumference of the lower end of the equipment compartment, and the embedded lever contacts the notch.

[0017] Preferably, the fall protection mechanism further includes a pusher frame, one end of which is a fixed end and the other end is a movable end. The movable end and the fixed end are connected by an electric telescopic rod, and a rotatable wheel is rotatably disposed inside the movable end.

[0018] Preferably, the positioning pusher is T-shaped with an outer arc, and the surface of the positioning pusher is provided with teeth that press against the inner wall of the well.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This safety device for the construction of the casing wall in a mining vertical shaft, by setting up a suspended top cover and positioning components, can effectively block falling objects such as gravel and tools from above the shaft opening, avoiding injury to underground construction personnel. At the same time, before construction, the suspended top cover can be supported and fixed by the positioning push rod of the suspended top cover to prevent the casing wall construction chamber from easily shaking after the hoisting system stops. The casing wall construction chamber, through the setting of the support frame, guard rod and construction ladder components, can create a good working environment, thereby greatly improving the safety of casing wall construction and reducing the construction risks caused by falling objects from above and shaking of the construction position.

[0021] 2. The safety device for the construction of the casing wall in the mining vertical shaft forms a double positioning and fixing structure through the positioning push frame of the suspended top cover and the positioning component at the lower end of the casing construction chamber. Both sets of structures are in pressure contact with the shaft wall, which can effectively prevent the overall device from shaking, tilting and rotating inside the shaft, making the construction environment inside the casing construction chamber more stable, achieving the effect of efficiently fixing the construction environment, and solving the problem that tilting at the construction position can easily cause tools to slip and cause injury to construction personnel.

[0022] 3. The safety device for the construction of the shaft casing in this mining vertical shaft has multiple layers of fall protection by setting an anti-fall mechanism at the lower end of the equipment compartment. When the device fails to suspend and begins to slide, the actuating wheel contacts and rotates with the shaft wall, which drives the embedded lever to rotate and obliquely insert into the gap or uneven part of the shaft wall, effectively preventing the device from falling continuously. This buys time for the escape of construction personnel and the repair of equipment, and further improves the safety protection level of the device. Attached Figure Description

[0037] like Figure 1-9 As shown, a safety device for the construction of a mining vertical shaft casing includes a shaft hoisting mechanism 1, a suspended top cover 2, a casing construction chamber 3, a positioning component 4, an equipment compartment 5, and a fall protection mechanism 6.

[0038] The derrick hoisting mechanism 1 is installed on the derrick erected outside the wellhead for suspending and controlling the height. The suspension top cover 2 is located at the end of the steel wire rope below the derrick hoisting mechanism 1. The suspension top cover 2 is used to block falling objects from above inside the well. The wall-mounted construction chamber 3 is fixedly connected to the suspension top cover 2. The wall-mounted construction chamber 3 supports an independent space inside the well for safe construction. The positioning component 4 is located at the lower end of the wall-mounted construction chamber 3. The positioning component 4 is in contact with the well wall to fix the position of the wall-mounted construction chamber 3. The equipment chamber 5 is fixedly connected to the bottom surface of the wall-mounted construction chamber 3. The lower end of the equipment chamber 5 is equipped with a grabbing device and a water pump system for working inside the well. The fall protection mechanism 6 is located at the lower end of the equipment chamber 5. The fall protection mechanism 6 is used to prevent the equipment chamber 5 from falling.

[0039] By utilizing the suspended top cover 2, positioning components 4, and anti-fall mechanism 6, the wall-mounted construction chamber 3 is fixed inside the well shaft in three sections, making the construction environment inside the wall-mounted construction chamber 3 more stable and preventing falls. The suspended top cover 2 also ensures that the construction inside the well shaft will not be injured by falling objects from above.

[0040] In an optional embodiment, the derrick hoisting mechanism 1 includes a positioning and hoisting frame 11, a winch system 12, and a control unit 13. The positioning and hoisting frame 11 is set above the derrick erected at the wellhead and serves as a hoisting and lifting platform. The winch system 12 can control the height of the suspended top cover 2 inside the well shaft by winding the wire rope. The control unit 13 is used to control the winch system 12, the suspended top cover 2, the positioning component 4, the equipment compartment 5, and the fall arrest mechanism 6.

[0041] In this embodiment, the positioning and hoisting frame 11 is welded from H-beams and has leveling bolts at its bottom, which can be adjusted horizontally according to the installation surface of the wellhead frame to ensure the installation level of the hoisting system 12. The braking device of the hoisting system 12 is an electromagnetic brake, which can lock the wire rope instantly in the event of power failure or emergency stop, effectively preventing the device from slipping down unexpectedly.

[0042] In an optional embodiment, the suspended roof cover 2 includes a suspended shell 21, a positioning pusher 22, and a pushing disc 23. The suspended shell 21 is connected to the wire rope of the hoisting system 12. The surface of the suspended shell 21 is provided with holes to facilitate the vertical transport of items into the wall-mounted construction chamber 3. The upper surface of the positioning pusher 22 is slidably connected to the inner wall of the suspended roof cover 2. The end of the positioning pusher 22 away from the center of the suspended shell 21 is provided with teeth, and the lower surface of the end near the center of the suspended shell 21 is provided with a sliding groove. The sliding groove is in sliding contact with the pushing disc 23. A drive motor 24 is provided inside the suspended roof cover 2, and the output end of the drive motor 24 is fixedly connected to the center of the pushing disc 23.

[0043] In this embodiment, the arc-shaped structure of the suspension shell 21 is consistent with the curvature of the inner wall of the well shaft. A wire rope connecting seat is provided at its top. The connecting seat is made of alloy steel and can bear the weight of the entire device and construction load. The suspension shell 21 has sufficient impact resistance and can effectively resist the impact of falling objects from above. A wear-resistant slider is provided between the positioning pusher 22 and the slide rail on the inner wall of the suspension shell 21, which can reduce the friction when the positioning pusher 22 slides and reduce component wear.

[0044] In an optional embodiment, the pusher plate 23 is disposed inside the suspension housing 21, and the upper surface of the pusher plate 23 is provided with an annular wave-shaped slide rail, which cooperates with the slide groove of the positioning pusher 22.

[0045] In this embodiment, a bearing is provided between the pushing plate 23 and the suspension shell 21 to ensure the smooth rotation of the pushing plate 23. The height difference between the crest and trough of the wave-shaped slide rail is designed according to the maximum extension distance of the positioning pusher 22 to ensure that the positioning pusher 22 can fully extend and make close contact with the well wall.

[0046] In an optional embodiment, the wall-mounted construction chamber 3 includes a support frame 31, a protective rod 32, and a construction ladder assembly 33. The lower end of the support frame 31 is a support plate, and the upper end is a support rod. The top of the support rod is fixedly connected to the suspension shell 21. The protective rod 32 is set at the edge of the support frame 31 for support and protection. The construction ladder assembly 33 includes two sets of upper and lower rails and a climbing ladder. The upper and lower sets of rails are respectively set on the surfaces of the suspension shell 21 and the support frame 31. The climbing ladder is provided with sliders at both the upper and lower ends, and the sliders are slidably connected to the rails.

[0047] In this embodiment, the support plate surface of the support frame 31 is covered with anti-slip patterned steel plate to prevent construction workers from slipping during construction; the guard rod 32 has a gripping and anti-slip effect; the slider of the construction ladder assembly 33 is provided with a positioning pin between it and the track bar, which can fix the climbing ladder at any position on the track bar, making it convenient for construction workers to work at fixed points.

[0048] In an optional embodiment, the positioning component 4 includes a lifting system 41 and a positioning slider 42. The center of the lifting system 41 is a telescopic rod, and a folding rod is hinged to the free end of the telescopic rod. The surface of the positioning slider 42 is slidably connected to the bottom surface of the support frame 31, and an anti-slip surface is provided on the end face of the positioning slider 42. The folding rod of the lifting system 41 is hinged to the positioning slider 42.

[0049] In this embodiment, the telescopic rod can be extended and retracted to allow the folding rod to push the positioning slider 42 close to and press against the inner wall of the well. The anti-slip surface on the end face can effectively increase the friction with the well wall, ensuring a good positioning effect even when the well wall is wet.

[0050] In an optional embodiment, the fall arrestor 6 includes a deflector wheel 61 and an embedded lever 62. The surface of the deflector wheel 61 is provided with a deflector plate, which contacts the inner wall of the shaft. The embedded lever 62 is a bent flat plate provided on the outside of the deflector wheel 61. The embedded lever 62 is fixedly connected to the deflector wheel 61. A notch is provided on the lower outer peripheral surface of the equipment compartment 5, and the embedded lever 62 contacts the notch.

[0051] In this embodiment, the actuating plate of the actuating wheel 61 is made of rubber with anti-slip texture on its surface. The rotating shaft of the actuating wheel 61 is equipped with a damping structure to prevent the actuating wheel 61 from rotating arbitrarily during normal lifting and lowering of the device. The bend of the embedded lever 62 is chamfered to avoid the sharp part scratching the well wall and to facilitate embedding into the gap of the well wall. The embedded lever 62 has sufficient bending strength to withstand the impact force of the device falling.

[0052] In an optional embodiment, the fall arrestor 6 further includes a pusher frame 63, one end of which is a fixed end and the other end is a movable end. The movable end and the fixed end are connected by an electric telescopic rod, and a swivel wheel 61 is rotatably disposed inside the movable end.

[0053] In this embodiment, the electric telescopic rod of the pusher 63 is waterproof and can work normally in a humid environment of the well. The moving end is equipped with a guide rod that passes through the fixed end and slides with the fixed end to ensure the straightness of the movement of the moving end, prevent the actuating wheel 61 from deviating, and ensure precise contact with the well wall.

[0054] In an optional embodiment, the positioning pusher 22 is T-shaped with an arc-shaped outer side, and the surface of the positioning pusher 22 is provided with teeth that press against the inner wall of the well.

[0055] In this embodiment, when the positioning pusher 22 is pushed out, it uses its teeth to squeeze and bite against the inner wall of the well, so that the position of the suspended top cover 2 can be fixed and can withstand the impact force brought by falling objects.

[0056] When in use, first fix the positioning and hoisting frame 11 of the derrick hoisting mechanism 1 to the derrick erected above the wellhead with anchor bolts. Adjust the frame to a horizontal state with leveling bolts. Complete the installation and wiring of the winch system 12 and control unit 13. Check the connection status and working performance of each mechanism to ensure that the equipment is operating normally.

[0057] Subsequently, the winch system 12 is activated via the touchscreen display of the control unit 13, controlling the winch to release the wire rope, allowing the suspended top cover 2 and the wall-mounted construction chamber 3 to be slowly lowered into the well. Construction personnel can then enter the wall-mounted construction chamber 3 and control the lifting speed of the device in real time via a wireless remote control. When the wall-mounted construction chamber 3 reaches the preset construction position inside the well, the control unit 13 activates the braking device of the winch system 12 to lock the wire rope and stop the device's lifting.

[0058] Next, the device is positioned and fixed: First, the control unit 13 controls the drive motor 24 inside the suspended top cover 2 to drive the pusher plate 23 to rotate inside the suspended shell 21. The wave-shaped slide rail of the pusher plate 23 pushes the positioning pusher 22 to slide radially outward along the suspended shell 21, so that the teeth on the surface of the positioning pusher 22 fit and press against the inner wall of the well, completing the positioning of the device at the top of the well, preventing the wall-mounted construction chamber 3 from shaking due to the traction end during the suspension process; at the same time, the control unit 13 controls the lifting system 41 of the positioning component 4 to operate, the electric telescopic rod extends upward, drives the folding rod to unfold, and pushes the positioning slider 42 to slide radially outward along the support frame 31, so that the anti-slip surface of the positioning slider 42 is in close contact with the inner wall of the well, completing the positioning and fixing of the lower end of the wall-mounted construction chamber 3, preventing the worker from sliding and falling due to the tilt of the lower pedal when working on the surface of the support frame 31. Through the double positioning at the top and bottom, the stability of the entire device in the well is ensured.

[0059] After positioning is completed, the control unit 13 controls the pusher 63 of the fall protection mechanism 6 to move, the electric telescopic rod pushes the moving end to move outward, and drives the actuating wheel 61 to press and fit against the well wall, completing the pre-start of the fall protection mechanism 6. At this time, the wall construction operation can begin. Construction personnel can work at different positions in the well through the construction ladder assembly 33. The grabbing equipment in the equipment compartment 5 can complete the hoisting and delivery of materials. The water pump system can pump out the water in the well in real time to ensure the smooth progress of construction.

[0060] During construction, if the device experiences suspension or positioning failure and tends to slide downwards, the actuating wheel 61 will rotate rapidly under the friction with the well wall, causing the embedded lever 62 to rotate synchronously. The free end of the embedded lever 62 will be inserted obliquely into the gap or uneven part of the well wall due to rotation, forming a mechanical engagement with the well wall, effectively preventing the device from falling continuously and ensuring the safety of construction personnel inside the wall construction chamber 3.

[0061] After construction is completed, first control the electric telescopic rod of the pusher 63 of the fall arrest mechanism 6 to retract, so that the actuating wheel 61 is separated from the well wall. Then control the electric telescopic rod of the lifting system 41 of the positioning component 4 to retract, which drives the folding rod to retract, so that the positioning slider 42 is separated from the well wall. Then control the drive motor 24 of the suspended top cover 2 to rotate in the opposite direction, which drives the push plate 23 to rotate in the opposite direction, so that the positioning pusher 22 retracts to the inside of the suspended shell 21, releasing the contact with the well wall. Finally, start the winch system 12 through the control unit 13 to wind up the wire rope and lift the entire device to the ground, completing the construction operation.
