Description

Technical Field

[0001] This invention relates to the field of manned elevator shaft equipment, specifically a manned elevator device for going up and down a shaft. Background Technology

[0002] Currently, ladders are commonly used to transport personnel up and down the well. However, using ladders is not only inefficient but also does not save manpower. If the passage is too long, climbing up and down the ladder consumes a lot of the staff's energy, which can lead to the inability to effectively complete the work.

[0003] In existing technologies, to facilitate lifting and lowering, guide rails are installed on steel ladders to allow workers to descend quickly inside the well, thereby improving the efficiency of going up and down the well. However, this method is less safe and prone to accidents. Since the well opening is generally small, it is also inconvenient to install conventional elevators for transportation. Therefore, there is an urgent need in the field of personnel lifting well equipment to be able to safely carry people up and down the well quickly. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot simultaneously achieve both safety and efficiency in going up and down wells. It provides a manned lifting device for going up and down wells, which improves the efficiency and safety of the lifting vehicle during the lifting process by combining upper guide wheel assembly and lower guide wheel assembly, thereby enabling the invention to effectively carry people and efficiently complete the work of going up and down wells.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] A manned lifting device for going up and down a well includes a steel ladder, a guide rail on the steel ladder, an upper guide wheel assembly at the top of the guide rail, a lower guide wheel assembly at the bottom of the guide rail, and a lifting vehicle body on the guide rail capable of reciprocating along the guide rail.

[0007] A traction rope is provided between the upper guide wheel assembly and the lower guide wheel assembly. The traction rope is fixed to the lifting vehicle body. The upper guide wheel assembly can restrict or release the movement of the traction rope.

[0008] Currently, workers typically use ladders to go up and down wells, and ladders are standard equipment in the construction of various engineering wells. The number of existing engineering wells is extremely large, and some of them are used frequently and are quite deep, so using ladders to go up and down wells is very inconvenient and will increase safety risks over time.

[0009] This application aims to modify the existing method of accessing and exiting engineering wells, and can also be applied to newly built engineering wells. This application uses a steel ladder attached to the original climbing ladder and fixed to the well wall, thereby increasing multiple points of support, making the steel ladder more stable, and providing effective protection against equipment failure. In addition to supporting this embodiment, it can also reinforce the original climbing ladder. Guide rails are set on the steel ladder to guide the lifting vehicle. Through the pulling of the traction rope, and using the upper guide wheel combination and the lower guide wheel combination to provide tension and traction force for the traction rope, the lifting vehicle can slide stably on the guide rail. The upper guide wheel combination is used as the top fulcrum to support the traction rope, so that the traction rope can provide traction force.

[0010] Furthermore, a passenger trolley is fixed on the lifting vehicle body, and the passenger trolley adopts a cage-type body.

[0011] The lifting vehicle body is capable of self-prevention and fall-prevention limiting in the event of a fall.

[0012] In this embodiment of the application, by setting up a passenger-carrying trolley with a cage-like body, the purpose of protecting the passengers is effectively achieved, and the safety of the passengers is ensured by the self-fall-prevention limit of the lifting vehicle body.

[0013] Furthermore, a controller is provided on the cage-like vehicle body, and an operating handle is externally connected to the controller. The operating handle is fixed to the cage-like vehicle body.

[0014] The bottom of the cage-like vehicle body is equipped with a footboard, and a built-in anti-fall device is located below the footboard. The built-in anti-fall device is connected to the guide rail.

[0015] In this embodiment, the controller is used to operate the lifting of the lifting vehicle body, the operating handle is used to connect to the controller, and the operation handle is fixed to the cage-type vehicle body to effectively prevent the operation handle from falling to an uncontrollable position, thereby enhancing operational safety. The pedal is used to support the staff, and the built-in anti-fall device can prevent the lifting vehicle body from falling by locking the guide rail.

[0016] Furthermore, the guide rail includes a rail body, on which a plurality of limiting holes are provided. The limiting holes are evenly distributed along the movement direction of the lifting vehicle body. The built-in anti-fall device is provided with a limiting paddle, which can pry the limiting paddle into the limiting hole when the lifting vehicle body falls.

[0017] In this embodiment of the application, the rail is used to guide the lifting vehicle body, the limiting hole can engage with the limiting plate, and the limiting plate is fixed to the lifting vehicle body, so that the limiting plate can effectively limit the movement of the lifting vehicle body by engaging with the limiting hole.

[0018] Furthermore, the upper guide wheel assembly includes a wheel housing, inside which a guide wheel is provided. The rope of the traction rope passes through the wheel housing and rests on the guide wheel. A first sector support and a second sector support are fixed on the wheel housing. The guide wheel is located between the first sector support and the second sector support and is movably connected to the first sector support and the second sector support, respectively.

[0019] The guide wheel can rotate freely around its own axis.

[0020] In this embodiment, the wheel housing is used to protect the guide wheel, the guide wheel is used to provide a fulcrum for the rope and to act as a pulley, the first sector support and the second sector support are used to support the guide wheel and enable the guide wheel to rotate freely, so that the rope can move on the guide wheel, and the lifting vehicle can be effectively pulled by the traction rope to achieve the lifting function.

[0021] Furthermore, the first sector-shaped support includes a support shell, a friction assembly is provided inside the support shell, a limiting ball is provided on the friction assembly, the limiting ball penetrates the support shell and contacts the guide wheel, and the friction assembly can compress the limiting ball to abut against the guide wheel.

[0022] In this embodiment, the supporting shell is used to provide a supporting base for the guide wheel and the friction assembly. By pressing the guide wheel with the limiting ball on the friction assembly, the rotation of the guide wheel can be effectively limited by the friction force, thereby stopping the rotation of the guide wheel. When the guide wheel stops rotating, the traction rope can stop pulling the lifting vehicle body more quickly, thereby enabling the lifting vehicle body to stop and avoiding the safety risks caused by the inertial rotation of the guide wheel when stopping.

[0023] Furthermore, the friction assembly includes a guide rod, both ends of which are fixed to the supporting housing. A sliding rod is provided on the guide rod, and the sliding rod can slide freely along the guide rod.

[0024] The sliding rod is provided with a support part, the limiting ball is fixed to the support part, and the sliding rod can slide in the direction of pressing the guide wheel.

[0025] In this embodiment of the application, the guide rod is used to guide the sliding rod, thereby facilitating the driving of the sliding rod to press the limiting ball. The sliding rod is used to apply pressure to the limiting ball. In order to ensure that the pressure on the limiting ball is uniform, a support part is provided to apply pressure to the cross section of the limiting ball, so that the limiting ball is subjected to uniform force.

[0026] Furthermore, the structure of the second sector support is the same as that of the first sector support, and a connecting drive assembly for driving the friction assembly to abut against the guide wheel is provided between the first sector support and the second sector support.

[0027] In this embodiment, the limiting balls within the first and second sector supports are driven by the connecting drive component to synchronously perform frictional limiting on the guide wheel, thereby making the frictional resistance on the guide wheel more uniform and the locking process of the guide wheel more stable.

[0028] Furthermore, the connection drive assembly includes a connection housing, a rotating shaft is provided inside the connection housing, a drive gear is sleeved on the rotating shaft, a threaded rod is provided below the drive gear, one end of the threaded rod passes through the connection housing and extends into the support housing, and the other end is provided with a gear sleeve that meshes with the drive gear. A threaded end is provided inside the support housing, and the threaded end is fixed to the support housing. One end of the threaded rod passes through the sliding rod and is screwed to the threaded end, and the other end is screwed to the internal thread of the gear sleeve.

[0029] A stabilizing ring is provided between the threaded end and the sliding rod, and the stabilizing ring is sleeved on the threaded rod.

[0030] In this embodiment, the connecting housing is used to house and support its internal structure. The rotating shaft supports the rotation of the drive gear and provides a power source for the drive gear through a connected drive motor. The drive gear drives the gear sleeve to rotate. The gear sleeve is threadedly connected to the threaded rod. During the rotation of the gear sleeve, the screw-in depth between the threaded rod and the gear sleeve can be adjusted, thereby adjusting the position of the threaded rod to drive the sliding rod to move, thereby achieving the compression of the limiting ball. The stabilizing ring can use friction to restrict the rotation of the threaded rod, thereby realizing the screw-in and screw-out of the threaded rod on the gear sleeve. The threaded end provides extension and retraction space for the screw-in and screw-out of the threaded rod on the gear sleeve, and can also prevent the change of direction of the threaded rod when screwing in and out, thereby avoiding the risk of the threaded rod bearing excessive shear stress and enhancing its durability.

[0031] In summary, the present invention has the following advantages compared with the prior art:

[0032] (1) The present invention provides tension and traction force to the traction rope by pulling the traction rope and by using the upper guide wheel assembly and the lower guide wheel assembly, so that the lifting vehicle body can slide stably on the guide rail, and uses the upper guide wheel assembly as the top fulcrum to support the traction rope, so that the traction rope can provide traction force.

[0033] (2) In this invention, the supporting shell is used to provide a supporting base for the guide wheel and the friction assembly. By pressing the guide wheel with the limiting ball on the friction assembly, the rotation of the guide wheel can be effectively limited by the friction force, so that the guide wheel stops rotating. When the guide wheel stops rotating, the traction rope can stop pulling the lifting vehicle body more quickly, so that the lifting vehicle body can stop the operation and avoid the safety risk caused by the inertial rotation of the guide wheel when stopping.

[0034] (3) In this invention, the screwing depth of the threaded rod and the gear sleeve can be adjusted during the rotation of the gear sleeve, thereby adjusting the position of the threaded rod and driving the sliding rod to move, thereby achieving the pressure on the limiting ball. The stabilizing ring can use friction to restrict the rotation of the threaded rod, thereby realizing the screwing in and out of the threaded rod on the gear sleeve. The threaded end provides a telescopic space for the screwing in and out of the threaded rod on the gear sleeve, and can also avoid the change of direction when the threaded rod is screwed in and out, thereby avoiding the risk of the threaded rod bearing excessive shear stress and enhancing its own durability.

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0043] Example:

[0044] like Figures 1-5 As shown, a manned lifting device for going up and down a well includes a steel ladder 8, a guide rail 2 on the steel ladder 8, an upper guide wheel assembly 1 on the top of the guide rail 2, a lower guide wheel assembly 6 on the bottom of the guide rail 2, and a lifting vehicle 4 that can reciprocate along the guide rail 2.

[0045] A traction rope 3 is provided between the upper guide wheel assembly 1 and the lower guide wheel assembly 6. The traction rope 3 is fixed to the lifting vehicle body 4. The upper guide wheel assembly 1 can restrict or release the movement of the traction rope 3.

[0046] The lifting vehicle body 4 is fixed with a passenger-carrying trolley 7, which adopts a cage-type body 73;

[0047] The lifting vehicle body 4 is capable of self-prevention and fall-prevention limiting when it falls.

[0048] A controller 72 is provided on the cage-type body 73, and an operating handle 71 is externally connected to the controller 72. The operating handle 71 is fixed to the cage-type body 73.

[0049] The bottom of the cage-type vehicle body 73 is provided with a footboard 74, and a built-in anti-fall device 75 is provided below the footboard 74. The built-in anti-fall device 75 is connected to the guide rail 2.

[0050] In this embodiment, the steel ladder 8 is built on the existing ladder and wall of the engineering well. The guide rail 2 guides the lifting vehicle 4. The personnel trolley 7 can carry personnel up and down the well, and can also transport necessary materials without personnel. The upper guide wheel assembly 1 is the support point of the traction rope, and its rotation facilitates the pulling and releasing of the lifting vehicle 4 by the traction rope. In this embodiment, the traction rope 3 controls the lifting vehicle 4 through the operating handle 71 and the controller 72. Both the operating handle 71 and the controller 72 in this embodiment are models that can be mass-produced in the prior art, thus facilitating mass production. The cage-like body 73 can effectively resist external forces, thereby ensuring the safety of the personnel and avoiding injury caused by external forces due to equipment failure. The built-in anti-fall device 75 limits the lifting vehicle 4, ensuring sufficient safety for the lifting vehicle 4.

[0051] The guide rail 2 includes a rail body 21, and the rail body 21 is provided with a plurality of limiting holes 22. The limiting holes 22 are evenly distributed along the movement direction of the lifting vehicle body 4. The built-in anti-fall device 75 is provided with a limiting paddle 751. The built-in anti-fall device 75 can pry the limiting paddle 751 into the limiting hole 22 when the lifting vehicle body 4 falls.

[0052] The upper guide wheel assembly 1 includes a wheel housing 11, inside which a guide wheel 13 is provided. The rope 12 of the traction rope 3 passes through the wheel housing 11 and rests on the guide wheel 13. A first sector support 14 and a second sector support 16 are fixed on the wheel housing 11. The guide wheel 13 is located between the first sector support 14 and the second sector support 16 and is movably connected to the first sector support 14 and the second sector support 16 respectively.

[0053] The guide wheel 13 can rotate freely around its own axis 15.

[0054] In this embodiment, the limiting lever 751 can pop out and lock into the limiting hole 22 when the lifting vehicle body 4 falls rapidly, thereby preventing the lifting vehicle body 4 from descending. For example, since the lifting of the lifting vehicle body 4 is driven by the traction rope 3, when the traction rope 3 breaks, the lifting vehicle body 4 will fall. The limiting lever 751 can pop out when the traction rope 3 breaks, thereby limiting the fall of the lifting vehicle body 4 and ensuring the safety of the personnel and materials being transported.

[0055] The first sector-shaped support 14 includes a support housing 143, a friction assembly is provided inside the support housing 143, and a limiting ball 146 is provided on the friction assembly. The limiting ball 146 penetrates the support housing 143 and contacts the guide wheel 13. The friction assembly can press the limiting ball 146 against the guide wheel 13.

[0056] The friction assembly includes a guide rod 142, both ends of which are fixed to the support housing 143. A sliding rod 144 is provided on the guide rod 142, and the sliding rod 144 can slide freely along the guide rod 142.

[0057] The sliding rod 144 is provided with a support part 145, and the limiting ball 146 is fixed to the support part 145. The sliding rod 144 can slide in the direction of pressing the guide wheel 13.

[0058] The structure of the second sector support 16 is the same as that of the first sector support 14. A connecting drive assembly 17 for driving the friction assembly to abut against the guide wheel 13 is provided between the first sector support 14 and the second sector support 16.

[0059] The connecting drive assembly 17 includes a connecting housing 171, a rotating shaft 173 inside the connecting housing 171, a drive gear 174 sleeved on the rotating shaft 173, a threaded rod 172 below the drive gear 174, one end of the threaded rod 172 passing through the connecting housing 171 and extending into the supporting housing 143, and the other end having a gear sleeve 175 meshing with the drive gear 174. The supporting housing 143 has a threaded end 147 inside, and the threaded end 147 is fixed to the supporting housing 143. One end of the threaded rod 172 passes through the sliding rod 144 and is screwed onto the threaded end 147, and the other end is screwed onto the internal thread of the gear sleeve 175.

[0060] A stabilizing ring 148 is provided between the threaded end 147 and the sliding rod 144, and the stabilizing ring 148 is sleeved on the threaded rod 172.

[0061] In this embodiment, the limiting balls 146 in the first sector support 14 and the second sector support 16 are driven by the connecting drive component 17 to simultaneously perform friction limiting on the guide wheel 13, thereby making the frictional resistance on the guide wheel 13 more uniform and the locking process of the guide wheel 13 more stable.

[0062] The connecting housing 171 is used to house and support its internal structure. The rotating shaft 173 is used to support the rotation of the drive gear 174 and provides a power source for the drive gear 174 through a connected drive motor. The drive gear 174 is used to drive the gear sleeve 175 to rotate. The gear sleeve 175 is threadedly connected to the threaded rod 172. During the rotation of the gear sleeve 175, the screw-in depth of the threaded rod 172 and the gear sleeve 175 can be adjusted, thereby adjusting the position of the threaded rod 172 to drive the sliding rod 144 to move, thereby achieving the purpose of pressing the limiting ball 146. The stabilizing ring 148 can use friction to limit the rotation of the threaded rod 172, thereby realizing the screwing in and out of the threaded rod 172 on the gear sleeve 175. The threaded end 147 provides extension and retraction space for the screwing in and out of the threaded rod 172 on the gear sleeve 175, and can also prevent the change of direction of the threaded rod 172 when screwing in and out, thereby avoiding the risk of the threaded rod 172 bearing excessive shear stress and enhancing its own durability.

[0063] In this embodiment, a bellows 141 is sleeved on the guide rod 142. The bellows 141 is connected to an air pump. One end of the bellows 141 is fixed to the sliding rod 144, and the other end is fixed to the support housing 143. When the bellows 141 extends or retracts, it drives the sliding rod 144 to apply pressure to the limiting ball 146, thereby enhancing the friction between the limiting ball 146 and the guide wheel 13.
