Description

An emergency manned hoisting device for ultra-deep vertical shafts Technical Field

[0001] This invention relates to the field of emergency manned lifting technology, specifically to an emergency manned lifting device for ultra-deep vertical shafts. Background Technology

[0002] As a critical structure in infrastructure construction such as water conservancy projects, mining operations, and transportation tunnels, ensuring personnel safety during the construction and operation of shafts is of paramount importance in project management. The underground working environment is complex, and in the event of an emergency, such as a malfunction in transportation equipment or a sudden accident within the shaft, an independent and reliable emergency escape route becomes the last line of defense for personnel safety; its importance is self-evident.

[0003] Currently, the construction depth of vertical shafts in China is typically concentrated within 300 meters. For shafts of this depth, emergency ladders are usually installed inside the shaft, with rest platforms placed approximately every 50 meters along the ladders to form an emergency escape route. However, for deeper shafts, such as those exceeding 500 meters, the aforementioned ladder escape plan becomes difficult to implement. Climbing such long distances is unbearable for personnel, and even if they could barely climb out, the process would be accompanied by extremely high risks of falling and physical exhaustion, making it highly dangerous.

[0004] To address the emergency escape challenges in deep vertical shafts, some domestic projects have adopted the method of installing elevators within the shafts as emergency personnel transport. While this significantly improves escape efficiency and safety, the solution is limited by the internal structure and function of the shaft. Specifically, in many hydropower station projects, pressure steel pipes are installed inside the shafts as water diversion pipelines. These pipes are heavy and require frequent hoisting, necessitating the installation of large-tonnage gantry cranes or hoists on the shaft platform for their dedicated transport. Based on industry design experience, to ensure the smooth lowering of the pressure steel pipes, their diameter is generally about 1 meter smaller than the shaft diameter, meaning the clearance between the pipe and the shaft wall on each side is only about 50 cm. A shaft wall elevator system, including the car and guide rails, typically has an overall structural dimension of no less than 1.5 meters. If the elevator is fixedly installed on the shaft wall, its structure would occupy space within the shaft during operation and stops, making it impossible to meet the transport requirements of the pressure steel pipes and hindering the normal progress of shaft construction.

[0005] Therefore, it is necessary to develop a manned lifting device suitable for emergency escape in ultra-deep vertical shafts. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an emergency manned hoisting device for ultra-deep vertical shafts.

[0007] An emergency manned hoisting device for ultra-deep vertical shafts includes a carrying and transfer platform, a manned cage, and a traction mechanism, all located at the shaft opening or the middle branch tunnel area. The carrying and transfer platform includes two parallel and spaced guide rails, a movable carriage mounted on the guide rails, and a telescopic drive unit connecting the movable carriage. The telescopic drive unit drives the movable carriage to slide back and forth along the guide rails. A carrying frame for suspending the manned cage is mounted on the movable carriage. A steering pulley is mounted on the top of the carrying frame. The traction mechanism includes a winch mounted on one side of the guide rails and a wire rope mounted on the winch drum. The free end of the wire rope passes around the steering pulley and extends into the carrying frame, where it is fixedly connected to the top of the manned cage.

[0008] A further technical solution is: the movable carriage includes two parallel and spaced-apart slide rods and multiple connecting rods spaced apart along the length of the slide rods, and the slide rods slide in cooperation with the guide rail.

[0009] A further technical solution is: multiple stroke guiding components are provided on the outer side of the guide rail. The stroke guiding components include guide bearings and guide frames. The guide frames include two uprights provided on both sides of the guide rail. The top of the uprights extends to the top of the slide rod. A crossbar connects the two uprights. The inner ring of the guide bearing is coaxially sleeved in the middle of the crossbar. The outer ring of the guide bearing rolls against the top surface of the slide rod.

[0010] A further technical solution is: a first anchor is fixed to the outside of the guide frame, a reinforcing plate is welded between the first anchor and the guide frame, and the bottom end of the first anchor is anchored to the ground rock mass.

[0011] A further technical solution is that the movable carriage 23 is also provided with a diagonal bracing assembly, which includes multiple diagonally arranged diagonal bracing rods and reinforcing rods disposed between adjacent diagonal bracing rods. The two ends of the diagonal bracing rods are respectively fixed to the movable carriage and the load-bearing hanger to form a triangular load-bearing structure.

[0012] A further technical solution is as follows: a support base is provided below the end of the guide rail, a second anchor is provided on one side of the bottom of the support base, one side of the top surface of the support base is connected to the bottom surface of the guide rail, and the end of the guide rail terminates in the middle area of ​​the top surface of the support base; the other side of the support base extends outward relative to the end of the guide rail, and an upwardly protruding support section is formed on the top surface of the extended end, and the top surface of the support section slides in contact with the bottom surface of the slide rod extending to the end of the guide rail.

[0013] A further technical solution is: the traction mechanism adopts a double-drum winch and two sets of steel wire ropes. One end of the two sets of steel wire ropes is wound around the drum of the winch, and the other end passes over two sets of pulleys on the bearing frame and is fixedly connected to the manned cage.

[0014] A further technical solution is as follows: slide rails are provided on both sides of the inside of the load-bearing frame along its height direction, and rollers that cooperate with the slide rails are provided on both sides of the outside of the manned cage. A guide seat connected to the slide rail is provided at the bottom of the slide rail, and the entrance channel of the guide seat gradually decreases from bottom to top.

[0015] A further technical solution is as follows: the manned cage includes a cage frame, a lifting foundation is provided on the top of the cage frame, and lifting lugs for connecting steel wire ropes are provided on the lifting foundation; two sets of alignment components and two sets of locking components are provided between the load-bearing frame and the manned cage.

[0016] A further technical solution is as follows: The locking assembly includes two parallel locking plates disposed on the lower end face of the top crossbeam inside the load-bearing frame. A telescopic push rod is fixedly connected to the outer side of one of the locking plates, and the telescopic end of the telescopic push rod passes through the locking plate and extends outward. A mounting beam is provided on the top of the manned cage, and a mounting lug is provided on the upper end face of the mounting beam. A mounting hole is provided on the mounting lug. A corresponding locking hole is provided on the other locking plate. The telescopic end of the telescopic push rod can pass through the mounting hole and the locking hole in sequence to suspend the manned cage in the load-bearing frame. The alignment assembly includes an alignment cylinder disposed on the lower end face of the crossbeam and an alignment rod disposed on the upper end face of the mounting beam. A limit sensor is disposed inside the alignment cylinder, and a guide flare is disposed at the entrance of the alignment cylinder.

[0017] The beneficial effects of this invention are as follows: This application utilizes the upper opening or middle branch of a vertical shaft as an escape route, and sets up an emergency personnel hoisting device in the platform area of ​​the upper opening or middle branch. In the event of an emergency due to a malfunction of the shaft gantry crane or derrick, a telescopic drive mechanism can be used to move a mobile carriage along the guide rail towards the shaft. The personnel cage on the mobile carriage extends into the shaft, and a winch pulls the wire rope to raise and lower the personnel cage within the shaft, transporting the personnel inside to the outside for emergency escape. Under normal conditions, the mobile carriage retracts to an area outside the shaft structure line, without affecting the transport of pressure steel pipes or other objects within the shaft.

[0018] This invention innovatively designs a follow-up load-bearing and transfer platform, which makes the load-bearing frame serve as both a horizontal moving carrier for personnel cages and workers entering and exiting the shaft, and a pulley fulcrum for vertical lifting and lowering of personnel cages. This realizes the transfer operation between the shaft and the external space without the need for additional huge derricks or fixed suspension platforms, simplifying the overall structure of the machine. It solves the problem of limited equipment installation space in deep shaft construction, and also solves the problem of mutual interference between the emergency escape system and the main transportation system. This improves the on-site adaptability and construction efficiency of the equipment, and provides a solid safety guarantee for emergency rescue and personnel transfer in the shaft.

[0019] By incorporating guide seats, slide rails, and roller structures, the rollers are guided to precisely slide into the slide rails during lifting, maintaining relative stability of the personnel cage during horizontal movement and preventing swaying and positional deviation. Simultaneously, utilizing the synergistic effect of the alignment and locking components, the personnel cage is suspended and connected to the support frame via the locking component. When lowering is required, it is controlled to separate, and then smoothly lowered via a winch wire rope. After personnel are brought to the surface, precise positioning and safe docking are achieved through the alignment and locking components. Attached Figure Description

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] An emergency manned hoisting device for ultra-deep vertical shafts, as shown in Figures 1-9, includes a carrying and transfer platform 2, a manned cage 1, and a traction mechanism 4, all located at the shaft opening or the middle branch tunnel area. The carrying and transfer platform 2 includes two parallel and spaced guide rails 21, a movable carriage 23 mounted on the guide rails 21, and a telescopic drive component 22 connecting the movable carriage 23. The telescopic drive component 22 drives the movable carriage 23 to slide back and forth along the guide rails 21. A carrying frame 24 for suspending the manned cage 1 is mounted on the movable carriage 23. A steering pulley 27 is mounted on the top of the carrying frame 24. The traction mechanism 4 includes a winch 41 mounted on one side of the guide rails 21 and a wire rope 42 mounted on the drum of the winch 41. The free end of the wire rope 42 passes around the steering pulley 27 and extends into the carrying frame 24, and is fixedly connected to the top of the manned cage 1.

[0026] The movable carriage 23, driven by the telescopic drive component 22, slides back and forth along the guide rail 21, causing the supporting frame 24 to extend into or retract outside the shaft 6. During the horizontal movement of the movable carriage, the winch is configured to simultaneously release or retract the wire rope to match the horizontal displacement of the personnel cage. When the personnel cage reaches the inside of the shaft, the winch pulls the wire rope to vertically raise and lower it within the shaft. This device reduces the labor intensity and safety risks associated with climbing long ladders. Furthermore, by placing the personnel cage on the carrying and transfer platform, it can be moved between the inside and outside of the shaft according to operational needs, avoiding interference with other transportation systems within the deep shaft. This not only makes it convenient to use but also significantly improves the safety of shaft construction.

[0027] The guide rail 21 is made of two I-beams of the same length, laid parallel to each other and fixed at the wellhead or the middle branch opening area. The end of the guide rail 21 terminates outside the structural line of the vertical shaft 6. The corner of the guide rail 21 near the vertical shaft 6 is ground to form a rounded corner with a radius of 5cm to reduce the impact wear on the moving carriage 23 when it passes over it. Specifically, the guide rail 21 is made of I40 I-beams.

[0028] The movable carriage 23 includes two parallel, spaced-apart slide rods 231 and multiple connecting rods 232 spaced apart along the length of the slide rods 231. The two ends of each connecting rod 232 are fixedly connected to the two slide rods 231. The slide rods 231 are slidably engaged with the guide rails 21, allowing the two slide rods 231 of the movable carriage 23 to slide on the two guide rails 21 respectively. Specifically, the slide rods 231 and connecting rods 232 are made of I40 I-beams. The portion of the movable carriage 23 extending beyond the guide rails 21 can enter the vertical shaft 6.

[0029] Multiple travel guide components 5 are provided on the outer side of the guide rail 21. These travel guide components 5 guide the sliding of the movable carriage 23 on the guide rail 21. Each travel guide component 5 includes a guide frame 51 and a guide bearing 52. The guide frame 51 includes two uprights 511 located on both sides of the guide rail 21, with the tops of the uprights 511 extending above the slide rod 231. A crossbar 512 connects the two uprights 511. The inner ring of the guide bearing 52 is coaxially fitted into the middle of the crossbar 512, and the outer ring of the guide bearing 52 rolls against the top surface of the slide rod 231. Specifically, the guide bearing 52 is a ball bearing. The guide frame 51 surrounds the guide rail 21 and the slide rod 231 to constrain and guide the movement direction of the slide rod 231, ensuring that the movable carriage can move along a predetermined path when extending and retracting. Furthermore, the guide bearing 52, in cooperation with the slide rod 231, reduces friction.

[0030] A first anchor 513 is fixed to the outer side of the guide frame 51. The bottom end of the first anchor 513 is anchored to the ground rock. A reinforcing plate is welded and fixed between the first anchor 513 and the guide frame 51 to increase the welding area between the first anchor 513 and the guide frame 51, making the guide frame 51 more stable. Specifically, the first anchor 513 is an anchor rod with a diameter of 25mm, a length of 4.5m, an insertion depth of 3.5m into the rock, and a top bend of 0.2m. The reinforcing plate is a steel plate with a thickness of 1cm.

[0031] The load-bearing bracket 24 is welded and fixed to the sliding rod 231 and connecting rod 232 on the side of the movable slide 23 near the shaft 6. The spacing between the sliding rod 231 and connecting rod 232 is set to a size that allows the personnel cage 1 to pass smoothly. The load-bearing bracket 24 is constructed from multiple square tubes.

[0032] The movable carriage 23 is also equipped with a diagonal bracing assembly 25, which includes multiple diagonally arranged diagonal bracing rods and reinforcing rods disposed between adjacent diagonal bracing rods. The two ends of the diagonal bracing rods are respectively fixed to the movable carriage 23 and the load-bearing hanger 24 to form a triangular load-bearing structure. The diagonal bracing assembly 25 is used to improve the stability and strength of the load-bearing hanger 24 and ensure the stability of the movable carriage 23 during sliding.

[0033] A support base 3 is provided below the end of the guide rail 21. A second anchor 314 is provided on one side of the bottom of the support base 3. One side of the top surface of the support base 3 is connected to the bottom surface of the guide rail 21, and the end of the guide rail 21 terminates in the middle area of ​​the top surface of the support base 3. The other side of the support base 3 extends outward relative to the end of the guide rail 21, and an upwardly protruding support section 3131 is formed on the top surface of the extended end. The top surface of the support section 3131 slides in contact with the bottom surface of the slide rod 231 extending to the end of the guide rail 21.

[0034] Specifically, the support base 3 includes multiple parallel and spaced support frames 31, with multiple connecting rods 315 between adjacent support frames 31. Each support frame 31 is formed by connecting horizontal rods 311, first inclined rods 312, and second inclined rods 313, forming an overall triangular structure. Second anchors 314 are fixedly connected to the first inclined rods 312. A support section 3131 is positioned on the second inclined rod 313 directly below the guide rail 21. The top surface of the support section 3131 is horizontal and slides against the bottom surface of the sliding rod 231 of the movable slide 23. The second anchors 314 include multiple second anchor rods anchored to the ground at their bottoms. These second anchor rods are 25mm in diameter, 4.35m long, 3.5m deep into the rock, and bent 0.2m at the top. Multiple reinforcing rods 32 are installed within the support frame 31 to enhance its stability and strength.

[0035] The telescopic drive component 22 uses a telescopic hydraulic cylinder. One end of the cylinder is hinged to a ground anchor point via a pin, and the other end is connected to the movable slide 23 via a hinge seat. Specifically, a 5T telescopic hydraulic cylinder is selected, with a telescopic stroke of 3m. The cylinder is connected to the hydraulic station 9 via pipeline.

[0036] Support base 3 serves as the foundation for the emergency personnel lifting device. It is designed as a cantilever structure to reduce the shear force on the transport platform and to provide support for the movable carriage extending to the guide rail. During installation, a partial excavation is first carried out at the predetermined installation location to create space for installing support base 3. Support base 3 is positioned outside the structural line of shaft 6 to avoid interfering with the normal transport of pressure steel pipes within shaft 6.

[0037] The winch 41 of the traction mechanism 4 is fixedly mounted on the winch base 44, which is welded from I-beams. The contact portion between the base of the winch 41 and the winch base 44 is fully welded. The winch base 44 is connected and fixed to the ground by a third anchor 43. The third anchor 43 includes multiple third anchor rods whose bottoms are anchored into the ground rock mass, and whose tops are welded and fixed to the winch base 44. Specifically, the third anchor rods are 25mm in diameter, 4.35m in length, 3.5m into the rock mass, and bent 0.2m at the top. The winch 41 is a finished piece of equipment, including components such as a motor, reducer, and disc brake. The winch 41 pulls and brakes the wire rope 42.

[0038] Preferably, the traction mechanism employs a double-drum winch 41 and two sets of wire ropes 42. One end of each set of wire ropes 42 is wound around the drum of the winch 41, and the other end passes over two sets of steering pulleys 27 on the bearing frame 24 and is fixedly connected to the personnel cage 1. By setting two sets of wire ropes 42, the stability of the cage during operation is improved, and redundancy protection is achieved, ensuring that if one rope breaks, the other can independently bear the entire weight.

[0039] The support frame 24 has slide rails 28 installed on both sides along its height. The passenger cage 1 has rollers 14 installed on both sides of its exterior, which cooperate with the slide rails 28. A guide seat 29, connected to the slide rail 28, is installed at the bottom of the slide rail 28, and the entrance channel of the guide seat 29 gradually decreases in size from bottom to top. The rollers 14 are installed at positions corresponding to the slide rails 28. By installing the rollers 14 and the slide rails 28, the passenger cage 1 is stably suspended within the support frame 24, effectively preventing large-scale swaying when the passenger cage 1 moves.

[0040] The manned hoisting cage 1 includes a cage frame 11, with a lifting foundation 12 on top of the cage frame 11. Lifting lugs 13 for connecting the wire rope 42 are installed on the lifting foundation 12. Specifically, the cage frame 11 is formed by welding 150*150*7mm square tubing and angle steel. Multiple round steel bars are welded to form a safety door on the cage frame 11, and multiple angle steel bars are welded to form a protective rod. An iron plate is laid at the bottom of the cage frame 11. The lifting foundation 12 is made of 20 channel steel and welded to the top of the cage frame 11. The lifting lugs 13 are made of 32mm diameter round steel bent into shape. The wire rope 42 can be fixed to the lifting lugs 13 by hooks or clips.

[0041] Two sets of alignment components 7 and two sets of locking components 8 are provided between the support frame 24 and the passenger cage 1. The locking components 8 include two parallel locking plates 81 located on the lower end face of the top crossbeam 241 inside the support frame 24. A telescopic push rod 82 is fixedly connected to the outer side of one locking plate 81, and the telescopic end of the telescopic push rod 82 passes through the locking plate 81 and extends outward. A mounting beam 15 is provided at the top of the passenger cage 1, and a mounting lug 83 is provided on the upper end face of the mounting beam 15. The mounting lug 83 has a mounting hole. A corresponding locking hole is provided on the other locking plate 81. The telescopic end of the telescopic push rod 82 can pass through the mounting hole and the locking hole in sequence to suspend the passenger cage 1 within the support frame 24. The distance between the two parallel locking plates 81 can accommodate the thickness of the mounting lug 83, ensuring that the mounting lug 83 is located between the two locking plates 81. Specifically, the telescopic push rod 82 is an electric push rod or a hydraulic push rod.

[0042] The alignment assembly 7 includes an alignment cylinder 71 disposed on the lower end face of the crossbeam 241 and an alignment rod 72 disposed on the upper end face of the mounting beam 15. A limit sensor is installed inside the alignment cylinder 71, and a guide flare 73 is provided at the entrance of the alignment cylinder 71. The inner diameter of the guide flare 73 is larger than the outer diameter of the alignment rod 72, facilitating the insertion of the alignment rod 72 into the alignment cylinder 71. When the alignment rod 72 is inserted into the alignment cylinder, the limit sensor receives a signal and transmits a signal to the control terminal. The control terminal controls the telescopic push rod 82 to extend through the mounting hole on the mounting lug 83 and the locking hole of another locking plate.

[0043] Both the support frame 24 and the personnel cage 1 are equipped with monitoring cameras 17. The monitoring camera 17 on the support frame 24 is used to observe the alignment and connection status of the telescopic push rod 82 and the mounting lug 83. The monitoring camera 17 on the personnel cage 1 is used to observe the status of the personnel inside the personnel cage 1. The monitoring cameras 17 are connected to the ground control terminal.

[0044] In this embodiment, the emergency personnel hoisting device for ultra-deep vertical shafts is arranged at the shaft opening or the middle branch tunnel area, and is adapted to the actual depth of the shaft 6 and the on-site working conditions. It is also equipped with an electrical control cabinet 9, an operating console 10, a hydraulic station 15, and a depth indicator 16. The operating console 10 controls the winch 41 of the traction mechanism 4 and the telescopic drive of the transport platform 2.
