Technical Field
[0001] This invention relates to the field of manned platforms, and more particularly to a multi-level temporary lifting manned platform for vertical shafts. Background Technology
[0002] According to the design of a 600,000 t / a metal mine mining and beneficiation project, the development method is main shaft and auxiliary shaft development, the underground middle section transportation is rail transportation, and each section adopts trackless transportation.
[0003] After the wellbore is lowered to the bottom, the project will adopt multi-level simultaneous construction and will utilize the equipment from the well sinking period. The design of a temporary modification plan will take into account factors such as ensuring the safety of personnel going up and down, improving construction efficiency, and achieving rapid switching of processes.
[0004] The primary objective is to ensure the safety of the temporary manned platform during multi-level lifting. Through reasonable structural design and material selection, the risks that may occur during the use of the platform are reduced, and the platform design is optimized to adapt to the needs of multi-level lifting, improve the safety of personnel going up and down, and meet the operating space requirements of the hoisting bucket inside the shaft. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-level temporary lifting manned platform for vertical shafts.
[0006] This invention provides a multi-level temporary lifting manned platform in a vertical shaft, including a foundation pit, and further comprising:
[0007] A flip-type platform is installed at the platform mounting position via a drive device;
[0008] A support platform is installed at the platform installation location and is used to support the flip-type platform;
[0009] The hoisting bucket is installed inside the vertical shaft above the foundation pit using a winch;
[0010] The claw assembly is installed at the end of the tilting platform and is used to position the lifting bucket when the tilting platform is tilted to a horizontal state, so that the lifting bucket is stably stopped for personnel to get on and off.
[0011] Based on the foundation pit, the system mainly consists of a tilting platform, a support platform, a hoisting bucket, and a claw assembly. The tilting platform is installed at the platform mounting position with the help of a drive device. The support platform is also located at the same mounting position and provides necessary support for the tilting platform. The hoisting bucket is installed in the vertical shaft above the foundation pit by a winch. The claw assembly is installed at the end of the tilting platform. When the tilting platform tilts to a horizontal position, the claw assembly can accurately position the hoisting bucket, making it stable and allowing personnel to safely go up and down. This structural design can ensure the safety of personnel during multi-level hoisting. By rationally selecting the structure and materials, the risk of use is reduced, the multi-level hoisting needs are met, and the safety of personnel going up and down is improved. At the same time, it can also optimize the operating space of the bucket in the shaft. The tilting function of the platform can ensure the safe clearance during the operation of the bucket. With the help of dedicated personnel operation and communication, signaling, and interlocking facilities, smooth communication between the surface and underground can be achieved, thereby improving work efficiency, reducing costs, and shortening process changeover time. It has broad application value.
[0012] Preferably, the claw assembly includes:
[0013] Two jaws are installed at the ends of the tilting platform. After clamping the top of the lifting bucket, the two jaws move to both ends to support the two ends of the lifting bucket and reduce the back-and-forth swaying of the lifting bucket.
[0014] The two jaws of the clamping assembly are installed at the end of the tilting platform. When positioning the hoisting bucket, the two jaws first clamp the top of the bucket and then move to both ends, thus providing effective support at both ends of the bucket. Through the clamping and supporting action of the jaws, the swaying amplitude of the hoisting bucket in the front-to-back direction can be limited, thereby ensuring the stability of the bucket during personnel ascent and descent. This has several advantages: First, it greatly improves the safety of construction personnel when ascending and descending the bucket, avoiding accidents caused by excessive bucket swaying. Second, it helps improve the efficiency of the entire construction process, as the stable positioning of the bucket allows for faster and more orderly personnel ascent and descent, reducing waiting and adjustment time caused by bucket swaying. Third, this clamping assembly optimizes the operating space of the hoisting bucket within the shaft, enabling it to operate more smoothly during lifting between different levels, reducing the risk of collision between the bucket and the shaft wall or other equipment, and thus ensuring the smooth progress of construction.
[0015] Preferably, the claw assembly further includes:
[0016] The mounting box is installed at the end of the flip-up platform;
[0017] Two electric telescopic rods are fixed inside the two ends of the mounting box, and the telescopic ends of the two electric telescopic rods drive the two claws to move respectively;
[0018] A fixing plate is fixed inside the clamping groove at the top of the lifting bucket, and a flip plate is installed on one end of the fixing plate;
[0019] An elastic element is installed between the fixed plate and the flip plate to push the flip plate to flip outward;
[0020] The entire jaw assembly is fixed to the end of the tilting platform via a mounting box. Two electric telescopic rods are installed inside the mounting box at both ends. Their telescopic ends can drive the jaws to move, thereby achieving reliable clamping and effective support for the hoisting bucket. This helps to reduce the back-and-forth swaying of the bucket and ensure the safety of personnel going up and down. The fixing plate is installed in the clamping groove on the top of the hoisting bucket, with one end connected to the tilting plate. The elastic element pushes the tilting plate to tilt outward, allowing the jaws to better conform to the shape of the top of the hoisting bucket during clamping, enhancing the stability of the clamping. At the same time, when the bucket is lifted, the tilting plate can be smoothly reset, avoiding interference with the normal lifting of the bucket. This improves the safety and reliability of the entire temporary lifting personnel platform, effectively increases construction efficiency, reduces waiting and adjustment time caused by bucket swaying, ensures the smooth progress of multi-level lifting operations, reduces safety risks during construction, and provides a solid safety guarantee for the second-phase multi-level construction of the vertical shaft sinking system.
[0021] Preferably, it further includes:
[0022] Two sets of inner grooves, with multiple inner grooves forming a group, are respectively opened on both sides of the lifting bucket;
[0023] Several boxes are fixed inside each of the aforementioned inner grooves;
[0024] Several sets of first electric push rods are respectively fixed inside each of the aforementioned boxes;
[0025] Several push boxes are respectively fixed to the ends of the telescopic rods of each of the first electric push rods;
[0026] Multiple inner slots are grouped together and located on both sides of the hoisting bucket. Each inner slot contains a fixed box, inside which a first electric push rod is installed. The end of the push rod is fixed to a push box. When it is necessary to stabilize the hoisting bucket, the first electric push rod operates, driving the push box to move outward until the push box contacts the inner wall of the shaft. This achieves lateral positioning and stabilization of the hoisting bucket, preventing it from swaying within the shaft. The contact with the inner wall of the shaft also protects the inner wall to a certain extent, avoiding damage caused by collisions between the bucket and the inner wall. This design optimizes the operating space of the bucket within the shaft, making it adaptable to the needs of multi-level construction and ensuring the reliable operation of personnel and materials during construction.
[0027] Preferably, it further includes:
[0028] Several springs are respectively fixed to the side wall of each of the push boxes;
[0029] Multiple extrusion plates, and the springs corresponding to the first electric push rods in the same group are all fixed to the side wall of the same extrusion plate;
[0030] Multiple pressure sensors are fixed to the sidewalls of each of the extrusion plates;
[0031] Multiple inner slots are provided on both sides of the hoisting bucket, and a box is fixed in each inner slot. The first electric push rod is installed in the box, and the end of its telescopic rod is connected to the push box. A spring is fixed on the side wall of the push box. The springs corresponding to the first electric push rods in the same group are connected to the side wall of a pressing plate. A pressure sensor is installed on the pressing plate. When the hoisting bucket needs to be stabilized after running to the designated position in the shaft, the first electric push rod pushes the push box to move outward. The push box drives the pressing plate to press tightly against the inner wall of the shaft through the spring. The elasticity of the spring can buffer and adapt to the unevenness of the inner wall of the shaft, so that the pressing plate is tightly fitted, which enhances the stability of the hoisting bucket. The pressure sensor monitors the pressure between the pressing plate and the inner wall of the shaft in real time, ensuring that the pressure of the pressing plate on the inner wall of the shaft is within a safe range, preventing the hoisting bucket from shaking due to insufficient pressure or damaging the inner wall of the shaft due to excessive pressure. It can effectively prevent the hoisting bucket from shaking, ensure the safety of personnel going up and down, protect the inner wall of the shaft, and improve construction safety.
[0032] Preferably, it further includes:
[0033] Multiple openings are respectively opened at the center of each of the extrusion plates;
[0034] Multiple drive wheels are rotatably installed inside each of the openings;
[0035] Multiple motors are mounted on the side wall of the extrusion plate via adjusting components to drive the drive wheel to rotate;
[0036] The extrusion plate has an opening in the center, with a drive wheel installed inside. A motor is mounted on the side wall of the extrusion plate and connected to the drive wheel through an adjusting component. When the bucket moves inside the shaft, the motor drives the drive wheel to rotate. The opening allows the drive wheel to contact the inner wall of the shaft, generating friction to move the extrusion plate, thus achieving lateral fine-tuning and stabilization of the bucket. When the drive wheel rotates, the push box and the extrusion plate can slide along the inner wall of the shaft, reducing frictional resistance and improving movement efficiency. This structure allows the bucket to move more flexibly and stably inside the shaft, adapting to shafts of different diameters and improving construction efficiency and safety.
[0037] Preferably, the adjusting member includes:
[0038] The second electric push rod is fixed to the side wall of the extrusion plate;
[0039] A connecting bracket is fixed to the end of the telescopic rod of the second electric push rod;
[0040] The mobile box is fixed to the connecting frame, and the motor is fixed inside the mobile box;
[0041] The second electric push rod is fixed to the side wall of the extrusion plate, and its telescopic rod end is connected to the connecting frame. The moving box is fixed on the connecting frame, and the motor is installed inside the moving box. When it is necessary to adjust the contact pressure or position between the drive wheel and the inner wall of the shaft, the second electric push rod is activated, driving the connecting frame and the moving box to move as a whole, thereby changing the position of the motor and the drive wheel. During this process, the pressure sensor on the extrusion plate monitors the pressure against the inner wall of the shaft in real time and feeds the data back to the control system. Based on the feedback from the pressure sensor, the control system precisely adjusts the extension and retraction of the second electric push rod so that the drive wheel can extrude the inner wall of the shaft with appropriate force. This structure can not only adapt to shafts of different diameters or shapes, but also ensure that the drive wheel and the inner wall of the shaft maintain the best friction, effectively preventing the bucket from shaking and slipping in the vertical shaft, improving the stability and safety of the bucket operation. At the same time, this adjustable design also improves the versatility and flexibility of the equipment, and reduces the difficulty and time cost of equipment adjustment caused by changes in shaft conditions.
[0042] Preferably, it further includes:
[0043] The controller is installed inside the lifting bucket;
[0044] When in the positioning state, the first electric push rod pushes the push box to move until the pressure monitored by the pressure sensor reaches a specified value, and the controller controls the first electric push rod to stop pushing.
[0045] When in the adjustment state, the controller controls the second electric push rod to extend, while simultaneously controlling the first electric push rod to retract.
[0046] The controller activates the first electric push rod, which pushes the push box towards the inner wall of the shaft. When the push box contacts the inner wall of the shaft and gradually applies pressure, the pressure sensor monitors the pressure value in real time. Once the pressure reaches the preset value, the controller immediately controls the first electric push rod to stop pushing, ensuring that the pressure applied by the push box to the inner wall of the shaft is stable within a safe and effective range, thereby achieving stable positioning of the bucket, preventing the bucket from swaying in the vertical shaft, and ensuring the safety of personnel going up and down.
[0047] In the adjustment state, the controller activates the second electric push rod, extending its telescopic rod, while simultaneously controlling the first electric push rod to retract. This design allows for flexible changes in the distance between the push box and the inner wall of the shaft when the bucket needs to be repositioned or other operations are performed. By precisely controlling the extension and retraction of the second electric push rod, the contact pressure between the drive wheel and the inner wall of the shaft can be finely adjusted, ensuring the stability of the bucket during movement. This adjustment mechanism not only improves the adaptability of the bucket in shafts of different diameters or shapes but also enhances the flexibility and versatility of the equipment.
[0048] The intelligent management of the controller enables automated control of the bucket positioning and adjustment process, improving operational accuracy and safety. The real-time monitoring and feedback mechanism of the pressure sensor ensures that the pressure between the bucket and the inner wall of the shaft is always at the optimal level, reducing safety hazards caused by improper pressure. In addition, this design optimizes the operating space of the bucket in the shaft, enabling it to adapt to the needs of multi-level lifting, improving construction efficiency and reducing safety risks. The enhanced intelligence and automation of the entire system not only reduces the complexity of manual operation but also improves the overall construction efficiency, providing reliable technical support for multi-level shaft construction.
[0049] Preferably, the lifting bucket includes:
[0050] The car end and the sliding platform, wherein the sliding platform is adapted to the claw assembly for positioning, and the car end is used for bearing;
[0051] A slide rail is installed on the top of the car end, and the sliding table is installed on the slide rail via the slide table;
[0052] The hoisting bucket consists of a car end and a sliding platform. The car end is used to carry personnel or materials and has a chute on its top. The sliding platform is installed on the chute and is adapted to the claw assembly for easy positioning. When the claw assembly clamps the top of the hoisting bucket, the sliding platform can move along the chute and be positioned, so that the hoisting bucket can be stably stopped at different horizontal positions, ensuring the safe ascent and descent of personnel. By using the cooperation of the chute and the sliding platform, the hoisting bucket can be flexibly moved and positioned in the shaft. At the same time, the clamping of the claw assembly ensures the stability of the hoisting bucket when it is positioned.
[0053] This helps improve the positioning accuracy and stability of the hoisting bucket in the shaft, ensuring that the bucket will not sway during personnel movement, thus guaranteeing construction safety. Through the cooperation of the sliding platform and the chute, the hoisting bucket can be moved flexibly and positioned quickly at different horizontal positions, improving construction efficiency.
[0054] Preferably, it further includes:
[0055] The inner wall of the platform installation location, which connects to the shaft, is provided with an array of teeth adapted to the drive wheel;
[0056] When the hoisting bucket moves inside the shaft, the drive wheel engages with the array teeth on the inner wall of the shaft. The motor drives the drive wheel to rotate, and with the help of the array teeth, the bucket moves stably up and down or laterally along the shaft. Through the cooperation of the drive wheel and the array teeth, the rotational motion of the motor is converted into the linear motion of the bucket, achieving precise control. At the same time, the array teeth provide a biting force to prevent the bucket from slipping, ensuring smooth operation. This significantly improves the stability of the bucket's operation inside the shaft, reduces the safety risks caused by swaying, and ensures the safety of personnel going up and down by precisely controlling the position of the bucket, while also improving construction efficiency.
[0057] Compared with the prior art, the present invention has the following beneficial effects:
[0058] By optimizing the structure and materials, the platform reduces usage risks, meets multi-level hoisting needs, improves personnel safety during descent, optimizes the bucket's operating space within the shaft, and ensures safe clearance during bucket operation. Combined with dedicated personnel, communication, signaling, and interlocking facilities, it enables seamless communication between the surface and underground, thereby improving work efficiency, reducing costs, and shortening process changeover time. It has broad application value. Attached Figure Description

[0068] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0069] like Figures 1 to 8 The illustrated multi-level temporary lifting manned platform in a vertical shaft includes a foundation pit 104 and further includes:
[0070] The flip-type platform 101 is installed at the platform mounting position via a drive device;
[0071] Support platform 103 is installed at the platform installation location and is used to support the flip-type platform 101;
[0072] Lift bucket 1 and install it inside the vertical shaft above the foundation pit 104 using a winch;
[0073] The claw assembly 102 is installed at the end of the tilting platform 101 and is used to position the lifting bucket 1 when the tilting platform 101 is tilted to a horizontal state, so that the lifting bucket 1 is stably stopped for personnel to go up and down.
[0074] After the wellbore is lowered to the bottom, the project will adopt multi-level simultaneous construction and will utilize the equipment used during the well sinking period. The design of a temporary modification plan will take into account factors such as ensuring the safety of personnel going up and down, improving construction efficiency, and achieving rapid switching of processes.
[0075] The primary objective is to ensure the safety of the temporary manned platform during multi-level lifting. Through reasonable structural design and material selection, the risks that may occur during the use of the platform are reduced, and the platform design is optimized to adapt to the needs of multi-level lifting, improve the safety of personnel going up and down, and meet the operating space requirements of the hoisting bucket inside the shaft.
[0076] This embodiment of the invention can solve the above problems. The specific implementation is as follows: based on the foundation pit 104, it mainly consists of a tilting platform 101, a support platform 103, a lifting bucket 1, and a claw assembly 102. The tilting platform 101 is installed at the platform installation position using a driving device. The support platform 103 is also located at this installation position and provides necessary support for the tilting platform 101. The lifting bucket 1 is installed in the vertical shaft above the foundation pit 104 via a winch. The claw assembly 102 is installed at the end of the tilting platform 101. When the tilting platform 101 is tilted to a horizontal state, the claw assembly 102... 02 can accurately position the hoisting bucket 1, ensuring its stable parking for safe personnel access. This structural design guarantees personnel safety during multi-level hoisting. By optimizing the structure and materials, it reduces usage risks, meets multi-level hoisting requirements, improves personnel safety, optimizes the bucket's operating space within the shaft, and ensures safe clearance during bucket operation. Combined with dedicated personnel operation and communication, signaling, and interlocking facilities, it enables seamless communication between the surface and underground, thereby improving work efficiency, reducing costs, and shortening process changeover time. It has broad application value.
[0077] As an optional embodiment, the claw assembly 102 includes:
[0078] Two jaws 2 are installed at the ends of the tilting platform 101. After clamping the top of the lifting bucket 1, the two jaws 2 move to both ends to support the two ends of the lifting bucket 1 and reduce the back-and-forth swaying of the lifting bucket 1.
[0079] The two jaws 2 of the jaw assembly 102 are installed at the end of the tilting platform 101. When the hoisting bucket 1 needs to be positioned, the two jaws 2 first clamp the top of the hoisting bucket 1, and then move to both ends, thereby providing effective support to both ends of the hoisting bucket 1. Through the clamping and supporting action of the jaws 2, the swaying amplitude of the hoisting bucket 1 in the front-to-back direction can be limited, thus ensuring that the bucket remains stable during personnel as they go up and down. First, it greatly improves the safety of construction personnel when going up and down the bucket, avoiding safety accidents caused by excessive bucket swaying. Second, it helps to improve the efficiency of the entire construction process, because the stable parking of the bucket makes personnel going up and down more quickly and orderly, reducing the waiting and adjustment time caused by bucket swaying. Third, the setting of this jaw assembly 102 optimizes the operating space of the hoisting bucket 1 in the shaft, allowing it to run more smoothly during the lifting process between different levels, reducing the risk of the bucket colliding with the shaft wall or other equipment, and thus ensuring the smooth progress of construction.
[0080] As an optional embodiment, the claw assembly 102 further includes:
[0081] Mounting box 201 is installed at the end of the flip-up platform 101;
[0082] Two electric telescopic rods 202 are fixed inside the two ends of the mounting box 201 respectively, and the telescopic ends of the two electric telescopic rods 202 respectively drive the two claws 2 to move.
[0083] The fixing plate 203 is fixed inside the clamping groove at the top of the lifting bucket 1, and a flip plate 204 is installed on one end of the fixing plate 203.
[0084] The elastic element 205 is installed between the fixed plate 203 and the flip plate 204 and is used to push the flip plate 204 to flip outward.
[0085] The entire claw assembly 102 is fixed to the end of the tilting platform 101 via the mounting box 201. Two electric telescopic rods 202 are respectively installed inside the two ends of the mounting box 201. Their telescopic ends can drive the claws 2 to move, thereby achieving reliable clamping and effective support for the lifting bucket 1. This helps to reduce the back-and-forth swaying of the bucket and ensure the safety of personnel going up and down. The fixing plate 203 is installed in the clamping groove at the top of the lifting bucket 1. One end of the plate is connected to the tilting plate 204. The elastic element 205 pushes the tilting plate 204 to tilt outward, so that the claws 2 can better fit the shape of the top of the lifting bucket 1 during the clamping process, enhancing the stability of the clamping. At the same time, when the bucket is lifted, the tilting plate 204 can be smoothly reset, avoiding interference with the normal lifting of the bucket. This helps to improve the safety and reliability of the entire temporary lifting personnel platform, effectively improves construction efficiency, reduces waiting and adjustment time caused by bucket swaying, ensures the smooth progress of multi-level lifting operations, reduces safety risks during construction, and provides a solid safety guarantee for the second-phase multi-level construction of the vertical shaft sinking system.
[0086] As an optional embodiment, it also includes:
[0087] Two sets of inner grooves 303, and multiple inner grooves 303 are grouped together, and are respectively opened on both sides of the lifting bucket 1;
[0088] Several boxes 3 are fixed inside each inner groove 303;
[0089] Several sets of first electric push rods 302 are fixed inside each box 3 respectively;
[0090] Several push boxes 301 are respectively fixed to the ends of the telescopic rods of each first electric push rod 302;
[0091] Multiple inner grooves 303 are grouped together and are respectively opened on both sides of the hoisting bucket 1. Each inner groove 303 has a box 3 fixed inside, and a first electric push rod 302 is installed inside the box 3. The end of the telescopic rod is fixed to the push box 301. When it is necessary to stabilize the hoisting bucket 1, the first electric push rod 302 works, driving the push box 301 to move outward until the push box 301 contacts the inner wall of the shaft, thereby achieving lateral positioning and stabilization of the hoisting bucket 1 and preventing the hoisting bucket 1 from swaying in the vertical shaft. Through contact with the inner wall of the shaft, the inner wall of the shaft can be protected to a certain extent, avoiding damage caused by collision between the bucket and the inner wall. This design optimizes the operating space of the bucket in the shaft, making it adaptable to the needs of multi-level construction and ensuring the reliable operation of personnel and materials in the bucket during construction.
[0092] As an optional embodiment, it also includes:
[0093] Several springs 401 are fixed to the side walls of each push box 301;
[0094] Multiple extrusion plates 4 and springs 401 corresponding to the first electric push rod 302 in the same group are fixed together on the side wall of the same extrusion plate 4;
[0095] Multiple pressure sensors 402 are fixed to the side wall of each extrusion plate 4;
[0096] Multiple inner grooves 303 are provided on both sides of the hoisting bucket 1. A box 3 is fixed inside each inner groove 303, and a first electric push rod 302 is installed inside the box 3. The end of the push rod is connected to a push box 301. A spring 401 is fixed on the side wall of the push box 301. The springs 401 corresponding to the first electric push rods 302 in the same group are connected to the side wall of a pressure plate 4. A pressure sensor 402 is installed on the pressure plate 4. When the hoisting bucket 1 needs to be stabilized after moving to a designated position in the shaft, the first electric push rod 302 pushes the push box 301 outwards, pushing... Box 301 drives the extrusion plate 4 to fit tightly against the inner wall of the well shaft via spring 401. The elasticity of spring 401 can buffer and adapt to the unevenness of the inner wall of the well shaft, so that the extrusion plate 4 fits tightly, enhancing the stability of the hoisting bucket 1. Pressure sensor 402 monitors the pressure between the extrusion plate 4 and the inner wall of the well shaft in real time, ensuring that the pressure of the extrusion plate 4 on the inner wall of the well shaft is within a safe range, preventing the hoisting bucket 1 from shaking due to insufficient pressure or the inner wall of the well shaft from being damaged by excessive pressure. It can effectively prevent the hoisting bucket 1 from shaking, ensure the safety of personnel going up and down, protect the inner wall of the well shaft, and improve construction safety.
[0097] As an optional embodiment, it also includes:
[0098] Multiple openings 501 are respectively opened at the center of each extrusion plate 4;
[0099] Multiple drive wheels 5 are rotatably installed inside each opening 501;
[0100] Multiple motors 502 are mounted on the side wall of the extrusion plate 4 via adjusting components to drive the drive wheel 5 to rotate;
[0101] The extrusion plate 4 has an opening 501 at its center, and a drive wheel 5 is installed inside. A motor 502 is installed on the side wall of the extrusion plate 4 and is connected to the drive wheel 5 through an adjusting component. When the bucket moves in the shaft, the motor 502 drives the drive wheel 5 to rotate. The opening 501 allows the drive wheel 5 to contact the inner wall of the shaft, generating friction to drive the extrusion plate 4 to move, thus achieving lateral fine adjustment and stability of the bucket. When the drive wheel 5 rotates, the push box 301 and the extrusion plate 4 can slide along the inner wall of the shaft, reducing frictional resistance and improving moving efficiency. This structure allows the bucket to move more flexibly and stably in the shaft, adapting to shafts of different diameters and improving construction efficiency and safety.
[0102] As an optional embodiment, the adjusting member includes:
[0103] The second electric push rod 602 is fixed to the side wall of the extrusion plate 4;
[0104] The connecting bracket 601 is fixed to the end of the telescopic rod of the second electric push rod 602;
[0105] The movable box 6 is fixed on the connecting frame 601, and the motor 502 is fixed inside the movable box 6;
[0106] The second electric push rod 602 is fixed to the side wall of the extrusion plate 4, and its telescopic rod end is connected to the connecting frame 601. The moving box 6 is fixed on the connecting frame 601, and the motor 502 is installed inside the moving box 6. When it is necessary to adjust the contact pressure or position between the drive wheel 5 and the inner wall of the shaft, the second electric push rod 602 is activated, driving the connecting frame 601 and the moving box 6 to move as a whole, thereby changing the position of the motor 502 and the drive wheel 5. During this process, the pressure sensor 402 on the extrusion plate 4 monitors the pressure with the inner wall of the shaft in real time and feeds the data back to the control system. The control system precisely adjusts the extension and retraction degree of the second electric push rod 602 according to the feedback from the pressure sensor 402, so that the drive wheel 5 can extrude the inner wall of the shaft with appropriate force. This structure can not only adapt to shafts of different diameters or shapes, but also ensure that the drive wheel 5 maintains the best friction between the inner wall of the shaft and the shaft, effectively preventing the bucket from shaking and slipping in the vertical shaft, improving the stability and safety of the bucket operation. At the same time, this adjustable design also improves the versatility and flexibility of the equipment and reduces the difficulty and time cost of equipment adjustment caused by changes in shaft conditions.
[0107] As an optional embodiment, it also includes:
[0108] The controller is installed inside the hoisting bucket 1;
[0109] When in the positioning state, the first electric push rod 302 pushes the push box 301 to move until the pressure monitored by the pressure sensor 402 reaches the specified value, at which point the controller controls the first electric push rod 302 to stop pushing.
[0110] When in the adjustment state, the controller controls the second electric push rod 602 to extend, and at the same time controls the first electric push rod 302 to retract.
[0111] The controller activates the first electric push rod 302, which pushes the push box 301 towards the inner wall of the shaft. When the push box 301 contacts the inner wall of the shaft and gradually applies pressure, the pressure sensor 402 monitors the pressure value in real time. Once the pressure reaches the preset value, the controller immediately controls the first electric push rod 302 to stop pushing, ensuring that the pressure applied by the push box 301 to the inner wall of the shaft is stable within a safe and effective range, thereby achieving stable positioning of the bucket, preventing the bucket from swaying in the vertical shaft, and ensuring the safety of personnel going up and down.
[0112] In the adjustment state, the controller activates the second electric push rod 602, extending its telescopic rod, while simultaneously controlling the first electric push rod 302 to retract. This design allows for flexible changes in the distance between the push box 301 and the inner wall of the shaft when the bucket needs to be repositioned or other operations are performed. By precisely controlling the extension and retraction of the second electric push rod 602, the contact pressure between the drive wheel 5 and the inner wall of the shaft can be finely adjusted, ensuring the stability of the bucket during movement. This adjustment mechanism not only improves the adaptability of the bucket in shafts of different diameters or shapes but also enhances the flexibility and versatility of the equipment.
[0113] The intelligent management of the controller enables automated control of the bucket positioning and adjustment process, improving operational accuracy and safety. The real-time monitoring and feedback mechanism of the pressure sensor 402 ensures that the pressure between the bucket and the inner wall of the shaft is always at the optimal level, reducing safety hazards caused by improper pressure. In addition, this design optimizes the operating space of the bucket in the shaft, enabling it to adapt to the needs of multi-level lifting, improving construction efficiency and reducing safety risks. The enhanced intelligence and automation of the entire system not only reduces the complexity of manual operation but also improves the overall construction efficiency, providing reliable technical support for multi-level shaft construction.
[0114] As an optional embodiment, the lifting bucket 1 includes:
[0115] The car end and the sliding table 7 are positioned by being adapted to the claw assembly 102, and the car end is used for carrying.
[0116] The slide rail 701 is installed on the top of the car end, and the sliding table 7 is installed on the slide rail 701 via the slide table;
[0117] The hoisting bucket 1 consists of a car end and a sliding platform 7. The car end is used to carry personnel or materials, and its top is equipped with a slide groove 701. The sliding platform 7 is installed on the slide groove 701 and is adapted to the claw assembly 102 for easy positioning. When the claw assembly 102 clamps the top of the hoisting bucket 1, the sliding platform 7 can move and be positioned along the slide groove 701, so that the hoisting bucket 1 can be stably stopped at different horizontal positions, ensuring the safe ascent and descent of personnel. By utilizing the cooperation between the slide groove 701 and the sliding platform 7, the hoisting bucket 1 can be flexibly moved and positioned in the vertical shaft. At the same time, the clamping of the claw assembly 102 ensures the stability of the hoisting bucket 1 when it is positioned.
[0118] This helps improve the positioning accuracy and stability of the hoisting bucket 1 in the vertical shaft, ensuring that the bucket will not sway during personnel movement, thereby guaranteeing construction safety. Through the cooperation of the sliding platform 7 and the chute 701, the hoisting bucket 1 can be moved flexibly and positioned quickly at different horizontal positions, improving construction efficiency.
[0119] As an optional embodiment, it also includes:
[0120] The inner wall of the platform installation location, which connects to the shaft, is equipped with an array of teeth that are compatible with the drive wheel 5.
[0121] When the hoisting bucket 1 moves inside the shaft, the drive wheel 5 engages with the array teeth on the inner wall of the shaft. The motor 502 drives the drive wheel 5 to rotate. With the help of the array teeth, the bucket moves stably up and down or laterally along the shaft. Through the engagement of the drive wheel 5 and the array teeth, the rotational motion of the motor 502 is converted into the linear motion of the bucket, achieving precise control. At the same time, the array teeth provide a biting force to prevent the bucket from slipping, ensuring smooth operation. This significantly improves the stability of the bucket's operation inside the shaft, reduces the safety risks caused by swaying, and ensures the safety of personnel going up and down by precisely controlling the position of the bucket, while also improving construction efficiency.
[0122] The working principle of this invention is as follows: Based on the foundation pit 104, it mainly consists of a tilting platform 101, a support platform 103, a lifting bucket 1, and a claw assembly 102. The tilting platform 101 is installed at the platform mounting position by means of a driving device. The support platform 103 is also located at the mounting position and provides necessary support for the tilting platform 101. The lifting bucket 1 is installed in the vertical shaft above the foundation pit 104 by a winch. The claw assembly 102 is installed at the end of the tilting platform 101. When the tilting platform 101 is tilted to a horizontal state, the claw assembly 102 can lift the bucket 1. Precise positioning ensures stable parking for safe personnel access. This structural design guarantees personnel safety during multi-level hoisting. By optimizing the structure and materials, it reduces usage risks, meets multi-level hoisting requirements, improves personnel safety, optimizes the bucket's operating space within the shaft, and ensures safe clearance during bucket operation. Combined with dedicated personnel, communication, signaling, and interlocking systems, it enables seamless communication between the surface and underground, thereby improving work efficiency, reducing costs, and shortening process changeover time. This design has broad application value.
