Description

Technical Field

[0001] The present invention relates to the technical field of hoisting in narrow vertical shafts, and in particular to an intelligent hoisting mechanism in a vertical shaft and an application method thereof. Background Art

[0002] At present, the problem of vertical transportation has not been well solved in the construction process of buildings, especially in shaft buildings. The transportation of any equipment, building materials, auxiliary accessories and personnel must rely on tower cranes or elevators, and construction operations face multiple professions such as construction, mechanical and electrical, and decoration. Therefore, vertical transportation operations in shaft buildings face problems such as large total transportation volume, large single-unit transportation weight, high cost, and high lifting height. As a result, these two types of vertical transportation equipment are overwhelmed, and many lifting operations are forced to be carried out at night, resulting in construction disturbing the public.

[0003] Since tower cranes and elevators (generally external elevators) lack monitoring and intelligent braking equipment, they are greatly affected by the external environment during transportation and there are certain safety hazards. Once it rains or snows or the wind speed exceeds a certain level, the transportation operation will be forced to stop or be restricted, further delaying the construction progress. In addition, it is difficult to dismantle external elevators or tower cranes, and maintenance operations are also subject to environmental constraints, so the cost is high and the cycle is frequent.

[0004] When multiple operational conflicts arise in vertical transportation in shaft-type buildings, building materials are usually transported first (because structural acceptance comes first), which seriously affects the progress of mechanical, electrical and decoration projects, and further aggravates conflicts between professions.

[0005] When the pipe shafts in vertical shaft buildings or other buildings are completed with the completion of structural construction, they are often idle and temporary guardrails are set up around them to prevent falling from heights. Therefore, based on the above problems, it is urgent to develop a tooling that utilizes idle building space for vertical transportation, and at the same time has certain intelligence and safety to alleviate the above contradictions. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent lifting mechanism in a shaft and its application method that can improve safety, stability, accuracy and effectively solve common safety hazards and efficiency problems during the lifting process.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] An intelligent hoisting mechanism in a vertical shaft, used for carrying cargo in a narrow pipe shaft, characterized by comprising a rectangular frame, a telescopic device, and a hook;

[0009] The front and rear sides of the rectangular frame are respectively provided with door bodies, through which goods are placed into the rectangular frame;

[0010] The telescopic devices are arranged on the left and right sides of the rectangular frame, and are used to facilitate erection on the floor after a sudden drop during the hoisting process;

[0011] The hooks are multiple and evenly arranged on the top of the rectangular frame. The lifting mechanism arranged above the shaft is connected to the hooks through a steel wire rope to lift the rectangular frame into the narrow pipe shaft.

[0012] Among them, the hook is provided with a weight loss monitoring module, which is used to monitor in real time the force applied to the hook during the lifting or lowering process. When it is monitored that the force applied to the hook is lower than a threshold, it is determined that an abnormal situation exists, and the monitoring data is sent to the control system. The control system controls the telescopic device to open the safety hidden device erected on the floor to prevent further falling.

[0013] Preferably, the left and right sides of the rectangular frame are respectively provided with openable side doors for assisting in transporting goods out of the rectangular frame from the side.

[0014] Preferably, the telescopic device comprises a pair of upper telescopic devices and lower telescopic devices of identical structure;

[0015] A pair of upper telescopic devices are symmetrically arranged on both sides of the rectangular frame and located above the side-opening door, including an upper telescopic plate and an upper hydraulic rod. The upper hydraulic rod is connected to a control system, and by controlling the extension of the upper hydraulic rod, the upper telescopic plate is pushed to rotate, extend, open, or retract and close.

[0016] A pair of lower telescopic devices are symmetrically arranged on both sides of the rectangular frame and located below the side-opening door, including a lower telescopic plate and a lower hydraulic rod. The lower hydraulic rod is connected to a control system, and by controlling the extension of the lower hydraulic rod, the lower telescopic plate is pushed to rotate, extend, open, or retract and close.

[0017] The coverage area of ​​the upper and lower telescopic plates after being extended is larger than the pipe well area, and at the same time, the distance between the vertical edge projection line of the extended upper or lower telescopic plates and the floor slab is at least greater than 5 cm;

[0018] A rhythm controller is provided to coordinate the movement of the upper telescopic device and the lower telescopic device, so that the upper telescopic device and the lower telescopic device are alternately extended and retracted during the lifting or lowering process, thereby avoiding obstacles in the shaft and preventing the telescopic device from interfering with or colliding with the floor or obstacles in the shaft;

[0019] The outward turning angle of the upper and lower telescopic plates after the maximum rotation is 90 degrees. When the control system detects that there is an abnormal situation, the control system controls the upper and lower telescopic plates to extend and open at the same time, that is, after being extended and opened, they are perpendicular to the original movement path, so that when the rectangular frame falls, the upper and lower telescopic plates can be promptly supported on the nearest floor or obstacle structure in the shaft, playing a blocking and limiting role, preventing the rectangular frame from continuing to fall, thereby reducing safety hazards;

[0020] In addition, when the pipe well structure is limited and the side door cannot be opened, the upper telescopic plate or the lower telescopic plate is connected to the floor slab to form a transport ramp, and the goods can be dragged out smoothly.

[0021] Preferably, it further comprises a lifting device, which is arranged in the rectangular frame and comprises a lifting platform, a lifting hydraulic rod and a folding frame;

[0022] The lifting hydraulic rod is connected to the folding frame and is driven by a control system. The lifting hydraulic rod is controlled to push the folding frame to extend and open. The top of the folding frame is connected to the lifting platform, so that the lifting platform rises or falls within the rectangular frame, thereby raising or lowering the carried goods.

[0023] The cargo is adjusted to a plane flush with the side door through the lifting platform, so that the cargo can be smoothly moved out of the rectangular frame through the side door.

[0024] Preferably, the lifting device further comprises a guide plate and a longitudinal guide groove;

[0025] The guide plates are composed of two pieces, which are vertically arranged in a rectangular frame and located on both sides of the lifting platform. Longitudinal guide grooves are provided at opposite positions of the two guide plates. The two sides of the lifting platform are slidably arranged in the longitudinal guide grooves through guide blocks, thereby limiting the lifting range of the lifting platform.

[0026] Preferably, the lifting device further comprises a folding frame guide block;

[0027] The folding frame guide blocks are in two groups, which are respectively arranged at the bottom of the rectangular frame and the bottom of the lifting platform to limit the sliding range of the folding frame.

[0028] Preferably, it further comprises a weight sensor, which is arranged at the bottom of the rectangular frame and is used to measure the weight of the rectangular frame;

[0029] The weight sensor is electrically connected to the control system. When the rectangular frame suddenly loses weight or falls during the process of lifting or lowering, the weight of the rectangular frame detected by the weight sensor changes abnormally. The weight sensor feeds back the data of the abnormal change to the control system. The control system links the weight loss monitoring module to make a judgment based on the weight change. The control system triggers a safety control instruction to control the upper and lower telescopic plates to be supported on the nearest floor or obstacle structure in the shaft in time, thereby playing a blocking and limiting role, preventing the rectangular frame from continuing to fall, thereby effectively preventing the risk of falling and ensuring operational safety.

[0030] Preferably, it also includes a hoisting stabilization structure, which includes rope guides arranged on both sides of the door body. The rope guides are two groups of through-hole components symmetrically arranged on both sides of the door body. The steel wire hoisting rope used in the hoisting process passes through the through holes of the through-hole components, thereby achieving the effect of stabilizing transportation during the hoisting process to prevent shaking within the horizontal range.

[0031] Preferably, the top of the rectangular frame is provided with an openable top cover for assisting in transporting goods out from the top.

[0032] Furthermore, the present invention also provides an application method of an intelligent hoisting mechanism in a shaft, comprising the following steps:

[0033] Step S0: Before the lifting operation, start the control system of the intelligent lifting mechanism and complete the following initialization work:

[0034] Confirm that the rectangular frame has been installed in the shaft and that the guide and limit structures are intact;

[0035] Confirm that the lifting platform is in the initial position, and the telescopic device of the hanging device and the hook are in an operable state;

[0036] Start the weight sensor and weightlessness monitoring module, calibrate the sensors, and ensure the accuracy of monitoring data;

[0037] Step S1: Open the door or side door, place the cargo to be transported on the lifting platform, and use the weight sensor at the bottom of the lifting platform to detect whether the cargo meets the transport weight. During the lifting process, the weight sensor and the weight loss monitoring module form a logical relationship. When the weight sensor weighs the weight of the transported cargo, the weight loss monitoring module monitors the force on the hook in real time by setting the lifting or lowering acceleration limit to determine whether the lifting status is normal or abnormal.

[0038] Step S2: The control system adjusts the lifting hydraulic rod to drive the folding frame to extend and open, causing the lifting platform to descend, so that the goods are embedded in the rectangular frame to achieve stable transportation;

[0039] Step S3: A lifting mechanism disposed above the vertical shaft connects the lifting hook via a steel wire rope to lift the rectangular frame into the narrow pipe shaft, and then lifts and transports the rectangular frame from the narrow pipe shaft;

[0040] During the lifting and hoisting process, a beat controller is provided to coordinate the movement of the upper and lower telescopic plates, so that the upper and lower telescopic plates are alternately extended and retracted during the lifting process, thereby avoiding obstacles in the shaft and preventing the telescopic device from interfering with or colliding with the floor or obstacles in the shaft.

[0041] At the same time, the weightlessness monitoring module obtains the value of the force on the hook in real time and continuously transmits this data to the control system. The control system dynamically judges and analyzes the value of the force. When it detects that the force on the hook is less than the preset safety threshold, it determines that there is an abnormality in the current lifting state. Abnormal conditions include but are not limited to the hanging object falling off, the wire rope breaking, or the cargo is about to fall.

[0042] When it is determined to be an abnormal situation, the control system immediately issues a control command to control the upper and lower telescopic plates to be promptly supported on the nearest floor or obstacle structure in the shaft, playing a blocking and limiting role to prevent the rectangular frame from continuing to fall, thereby effectively preventing the risk of falling, blocking the hook or lifting platform from continuing to fall, preventing the rectangular frame from free falling, and ensuring operation safety;

[0043] Furthermore, when the rectangular frame suddenly loses weight or falls during the lifting process, causing the weight of the rectangular frame detected by the weight sensor to change abnormally, the weight sensor feeds back the data of the abnormal change to the control system, and the control system links the weight loss monitoring module to make a judgment based on the weight change. The control system triggers a safety control instruction to control the upper and lower telescopic plates to be supported on the nearest floor or obstacle structure in the shaft in time, thereby playing a blocking and limiting role, preventing the rectangular frame from continuing to fall, thereby effectively preventing the risk of falling and ensuring operational safety.

[0044] Step S4: In addition, by passing the steel wire rope through the rope guide on the outside of the rectangular frame, additional support can be provided to prevent the rectangular frame from shaking in the horizontal range during the lifting process;

[0045] Step S5: After the cargo is hoisted to the target location, the side door is opened, and the lifting hydraulic rod is controlled to push the folding frame to extend, thereby raising the height of the lifting platform so that the bottom surface of the cargo on the lifting platform is flush with the bottom surface of the side door;

[0046] Step S6: Adjust the lower hydraulic rod so that the lower telescopic plate contacts the plane of the floor slab. At this time, the slope formed by the lower telescopic plate is formed; guide the movement of the carried goods by the traction rope, and use the slope formed by the lower telescopic plate to smoothly drag the goods out of the rectangular frame;

[0047] Step S7: Similarly, when it is necessary to lower the telescopic plate for hoisting and transportation, the upper telescopic plate and the lower telescopic plate are also coordinated and controlled by setting a beat controller, so that the upper telescopic plate and the lower telescopic plate are alternately extended and retracted during the descent process, thereby avoiding obstacles in the shaft and preventing the telescopic device from interfering with or colliding with the floor or obstacles in the shaft;

[0048] In addition, during the hoisting process, the force value of the hook is monitored by the weight loss monitoring module, and the weight of the rectangular frame is detected by the weight detection sensor. When either the weight loss monitoring module or the weight detection sensor detects that the force on the hook is less than the preset safety threshold or the weight of the rectangular frame suddenly drops, the weight loss monitoring module or the weight detection sensor or both of them work together to quickly feed back the collected force value or weight data to the control system. The control system controls the upper and lower telescopic plates to rotate outward and open, so that they can be erected on the nearest two floor slabs in the shaft when falling, and will not continue to fall, thereby avoiding safety hazards of hoisting.

[0049] Compared with the prior art, the present invention has the following beneficial effects:

[0050] 1. Improve the safety of hoisting operations: The present invention uses a weight loss monitoring module and a weight sensor to monitor the force and weight changes during the hoisting process in real time. When it is found that the lifting is too fast, weight loss or abnormal falling occurs during the hoisting process, the control system immediately takes measures to support the rectangular frame on the floor or obstacle structure in the shaft through the telescopic device to prevent it from continuing to fall, thereby effectively preventing the risk of falling and wire rope breakage due to excessive lifting, and ensuring operational safety.

[0051] 2. Avoid damage to equipment and cargo: The telescopic device provided by the present invention (including the upper telescopic plate and the lower telescopic plate) can alternately extend and open and retract and close to avoid obstacles in the shaft, prevent the telescopic device from interfering with or colliding with the floor or other obstacles in the shaft, ensure the smooth progress of the lifting operation, and reduce the risk of damage to equipment and cargo.

[0052] 3. Improve the efficiency of hoisting operations: The system of the present invention can coordinate and control in real time during the hoisting process through intelligent control systems and automated adjustments, thereby improving the accuracy and efficiency of transportation operations, reducing human operational errors, and ensuring that all aspects of the hoisting process are efficient and orderly.

[0053] 4. Enhanced vertical transportation stability: The present invention prevents the rectangular frame from shaking horizontally during the lifting process by setting up rope guides, providing additional support, making the lifting operation more stable. It is especially suitable for vertical transportation in a small space, ensuring safety and reliability during the operation.

[0054] 5. Intelligent operation and control: The system of the present invention is equipped with an intelligent control system. By real-time feedback of monitoring data and dynamic adjustment of the telescopic device, it can independently judge and make safe decisions in complex environments, greatly reducing human operational errors and improving the safety and intelligence level of the construction process.

[0055] 6. Adaptability to various working environments: When the pipe well structure is limited during implementation, the present invention can form a transport ramp by connecting the upper telescopic plate or the lower telescopic plate with the floor slab, so that the goods can be smoothly dragged out from the rectangular frame, adapting to various working environments and complex operating conditions, and ensuring operational flexibility.

[0056] 7. Satisfy more hoisting environments: The top of the rectangular frame of the present invention is provided with an openable top cover, which can assist in transporting goods from the top of the rectangular frame, thereby satisfying more hoisting environments.

[0057] 8. Avoid risks and ensure safe construction: The present invention increases the operation of the rhythm controller to always ensure that the telescopic plate on one side can be opened to cover an area larger than the plane range of the pipe shaft, so that when the automatic control and sensor systems fail and the risk of falling occurs, the frame can be safely placed on the floor in the pipe shaft.

[0058] In summary, the present invention offers significant advantages in terms of safety, stability, accuracy, and operational flexibility, effectively addressing common safety hazards and efficiency issues during hoisting. Furthermore, the present invention utilizes the existing space within the shaft for intelligent hoisting, avoiding the noise and safety risks associated with high-altitude operations for surrounding residents, minimizing construction nuisance and improving the friendliness of the construction environment.

[0072] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0073] Example 1: Figures 1 to 6As shown, an intelligent hoisting mechanism in a vertical shaft and an application method thereof disclosed in the present invention are used to transport cargo in a narrow pipe shaft, comprising a rectangular frame 100, an upper telescopic device 200, a lower telescopic device 300, a hook 400 and a lifting device 500;

[0074] Door bodies 101 are respectively provided on the front and rear sides of the rectangular frame 100, and goods are placed into the rectangular frame 100 through the door bodies 101; openable side doors 103 are respectively provided on the left and right sides of the rectangular frame 100 to assist in transporting goods out of the rectangular frame 100 from the side.

[0075] The upper telescopic device 200 and the lower telescopic device 300 are each a pair, and the structures and movement directions of the two are the same; the pair of upper telescopic devices 200 are symmetrically arranged on both sides of the rectangular frame 100 and located above the side-opening door 103, including an upper telescopic plate 201 and an upper hydraulic rod 202. The upper hydraulic rod 202 is connected to the control system, and by controlling the extension of the upper hydraulic rod 202, the upper telescopic plate 201 is pushed to rotate and stretch to open; the pair of upper telescopic plates 201 corresponding to the pair of upper telescopic devices 200 are flipped and stretched in opposite directions and opened. After opening, they are like wings, and their coverage area should be larger than the area of ​​the pipe well, such as Figure 9 As shown, it is ensured that the distance between the projection line of the edge of the extended upper telescopic plate 201 or the lower telescopic plate 301 in the vertical direction and the floor 700 is at least greater than 5 cm.

[0076] A pair of lower telescopic devices 300 are arranged below the side-opening door 103, including a lower telescopic plate 301 and a lower hydraulic rod 302. The lower hydraulic rod 302 is connected to the control system, and by controlling the extension of the lower hydraulic rod 302, the lower telescopic plate 301 is pushed to rotate, stretch and open; the pair of lower telescopic plates 301 corresponding to the pair of lower telescopic devices 300 are flipped and stretched in opposite directions and opened. After opening, they are like wings, and their coverage area should also be larger than the pipe well area. At the same time, ensure that the projection line of the edge of the telescopic plate in the vertical direction is 5 cm outside the pipe well.

[0077] The control system can pre-calculate the desired extension angle of the telescopic rod based on the dimensions of the manhole and rectangular frame 100. It can also calculate the desired extension speed based on the lifting speed and floor height. For installations where the long side is large and the long side of the frame is small, different sized telescopic plates can be replaced. (This technical content is prior art and can be implemented using existing technology. It is not the technical solution of this embodiment and is therefore not detailed here.)

[0078] A rhythm controller is provided to coordinate the movement of the upper telescopic device 200 and the lower telescopic device 300, so that the upper telescopic plate 201 of the upper telescopic device 200 and the lower telescopic plate 301 of the lower telescopic device 300 alternately extend and retract during the lifting or lowering process. That is, when the upper telescopic plate 201 opens outward or retracts inward, the lower telescopic plate 301 moves in the opposite direction, but in the same direction. This avoids obstacles in the shaft and prevents interference or collision between the telescopic device and the floor slab 700 or obstacles in the shaft.

[0079] The specific implementation is as follows:

[0080] The rhythm controller independently controls the driving units of the upper telescopic device 200 and the lower telescopic device 300, and sets predetermined action rhythm parameters, including the stretching opening time, the contraction closing time, the movement amplitude and the action sequence.

[0081] During the lifting or lowering process, the rhythm controller controls the upper telescopic plate 201 to first extend according to the environmental parameters in the shaft or the preset obstacle information, and controls the lower telescopic plate 301 to be in a retracted and closed state.

[0082] When the upper telescopic plate 201 is extended to a preset position, the rhythm controller issues a switching instruction to control the lower telescopic plate 301 to start extending, while the upper telescopic plate 201 is contracted and closed synchronously, thereby achieving coordinated movement of the two alternatingly extending and contracting.

[0083] The rhythm controller dynamically adjusts the movement rhythm of the upper telescopic plate 201 and the lower telescopic plate 301 based on the real-time monitored position information, speed information and external obstacle detection information to ensure that the telescopic device can smoothly avoid the opening of the floor 700 or the obstacle position in the shaft to prevent collision or interference.

[0084] In special circumstances (such as detecting an abnormal obstacle, a weightless state or an emergency), the beat controller can immediately interrupt the current beat process, control the upper telescopic device 200 and the lower telescopic device 300 to simultaneously retract and close to a safe position, and start the safety protection process.

[0085] The outward turning angle of the upper telescopic plate 201 and the lower telescopic plate 301 after the maximum rotation is 90°. When the control system detects that there is an abnormal situation, the control system controls the upper telescopic plate 201 and the lower telescopic plate 301 to extend and open at the same time, that is, after extending and opening, they are perpendicular to the original movement path, so that when the rectangular frame 100 falls, the upper telescopic plate 201 and the lower telescopic plate 301 can be promptly supported on the nearest floor 700 or obstacle structure in the shaft, playing a blocking and limiting role, preventing the rectangular frame 100 from continuing to fall, thereby reducing safety hazards.

[0086] In addition, when the pipe shaft structure is limited and the door body 101 cannot be opened or transportation is required from the side door 103, the upper telescopic plate 201 or the lower telescopic plate 301 is connected to the floor 700 to form a transportation ramp, and the goods can be dragged out smoothly.

[0087] A plurality of hooks 400 are evenly arranged on the top of the rectangular frame 100. A lifting mechanism arranged above the shaft connects the hooks 400 via a steel wire rope to lift the rectangular frame 100 into the narrow pipe shaft.

[0088] A weightlessness monitoring module is provided on the hook 400, which is used to monitor in real time the force applied to the hook 400 during the lifting or lowering process. When it is detected that the force applied to the hook 400 is lower than a threshold value, it is determined that an abnormality exists, and the monitoring data is sent to the control system. The control system controls the upper telescopic plate 201 and the lower telescopic plate 301 to open, thereby erecting a safety hazard on the nearest floor slab 700 to prevent further falling.

[0089] The details are as follows: During the lifting process, the actual force (F) on the hook can be expressed as:

[0090] F = G + m × a

[0091] in:

[0092] G is the weight of the load (G = m × g)

[0093] m is the mass of the lifting object

[0094] g is the acceleration due to gravity (9.8 m / s²)

[0095] a is the acceleration of the ascent or descent (can be positive or negative)

[0096] Under normal working conditions:

[0097] When the lifting speed is constant (uniform motion, a = 0):

[0098] F = G = m × g

[0099] When there is a change in acceleration (acceleration or deceleration) during the lifting process, the force on the hook changes with the acceleration.

[0100] Abnormal status judgment:

[0101] If the G detected by the load detection module exceeds the preset load threshold, it is judged as an overload state and protection is triggered.

[0102] If the F detected by the weightlessness monitoring module drops rapidly and is lower than a certain percentage (such as 20%) of the reference force value under normal working conditions, it is judged to be a weightlessness or rapid falling state.

[0103] Threshold setting method:

[0104] For example:

[0105] Freference = m × g. Weightlessness alarm trigger condition: F ≤ 0.8 × Freference or dynamically adjust the weightlessness trigger threshold based on historical operating data and experience.

[0106] The control system controls the upper telescopic device 200 and the lower telescopic device 300 to open so that they are erected on the floor slab 700 to prevent the safety hazard of further falling.

[0107] The lifting device 500 is disposed in the rectangular frame 100 and includes a lifting platform 501 , a lifting hydraulic rod 502 , a folding frame 503 , a guide plate 504 , a longitudinal guide groove 505 and a folding frame guide block 506 .

[0108] The lifting hydraulic rod 502 is connected to the folding frame 503 and is driven by a control system. By controlling the lifting hydraulic rod 502, the folding frame 503 is pushed to extend and open. The top of the folding frame 503 is connected to the lifting platform 501, so that the lifting platform 501 rises or falls in the rectangular frame 100, thereby raising or lowering the carried goods.

[0109] The cargo is adjusted to a plane flush with the side door 103 through the lifting platform 501 , so that the cargo can be smoothly moved out of the rectangular frame 100 through the side door 103 .

[0110] Two guide plates 504 are provided, which are vertically arranged in the rectangular frame 100 and located on both sides of the lifting platform 501. Longitudinal guide grooves 505 are provided at the relative positions of the two guide plates 504. The two sides of the lifting platform 501 are slidably arranged in the longitudinal guide grooves 505 through the guide blocks, thereby limiting the lifting range of the lifting platform 501.

[0111] There are two groups of folding frame guide blocks 506 , which are respectively arranged at the bottom of the rectangular frame 100 and the bottom of the lifting platform 501 , and are used to limit the sliding range of the folding frame 503 .

[0112] Furthermore, this embodiment also provides a hoisting stabilization structure on the door body 101, including rope guides 600 arranged on both sides of the door body 101. The rope guides 600 are two groups of through-hole components symmetrically arranged on both sides of the door body 101. The steel wire hoisting rope used in the hoisting process is passed through the through holes of the through-hole components, thereby achieving the effect of stabilizing transportation during the hoisting process.

[0113] Furthermore, in this embodiment, an openable top cover 102 is provided on the top of the rectangular frame 100 , and the top cover 102 can assist in transporting cargo out of the top of the rectangular frame 100 , thereby meeting more hoisting environments.

[0114] The top lifting process is as follows:

[0115] (1) Hoisting to a fixed floor, the upper telescopic plate 201 is opened to contact the floor slab 700, and the rectangular frame 100 is safely placed on the floor slab 700. The crane releases the hook 400 through the wire rope, and the crane is connected to the auxiliary hook 104 through the wire rope, and the top cover 102 is opened;

[0116] (2) At this time, the rectangular frame 100 is safely placed on the floor 700 and does not require the force of the top crane. The crane further lifts out the cargo in the rectangular frame 100.

[0117] (3) After lifting out, the cargo is moved horizontally or a trailer with a platform area that can fully cover the pipe well is placed into the pipe well. The cargo is placed on the trailer and the cargo is moved out of the pipe well by moving the trailer out.

[0118] (6) Install the top cover 102 in sequence, plug in the latches on the top plate and the edge of the top frame, and then connect the hook 400 to the wire rope of the crane, and then enter the descending mode.

[0119] Furthermore, in this embodiment, a weight sensor is provided at the bottom of the rectangular frame 100 . The weight sensor is provided at the bottom of the lifting platform 501 and is used to weigh the weight of the transported goods.

[0120] The weight sensor is electrically connected to the control system, and the weight sensor and the weight loss monitoring module form a logical relationship. When the weight sensor weighs the weight of the transported goods, the weight loss monitoring module monitors the force on the hook 400 in real time by setting the lifting or lowering acceleration limit, and determines whether the lifting state is normal or abnormal; the weight loss monitoring module feeds back the data of the abnormal state to the control system, and the control system triggers a safety control instruction to control the upper telescopic plate 201 and the lower telescopic plate 301 to be able to be supported on the nearest floor or obstacle structure in the shaft in time, playing a blocking and limiting role, preventing the rectangular frame 100 from continuing to fall, thereby effectively preventing the risk of falling and ensuring operational safety.

[0121] It also includes a gravity limiter, a levelness monitoring module, a running speed detection module and a load-bearing sensing module; the gravity limiter, the levelness monitoring module, the running speed detection module and the load-bearing sensing module are uniformly connected to the control end through signals to achieve emergency stopping.

[0122] Furthermore, when the lifting device drives the lifting component to rise and fall along the pipe shaft, the control system triggers a warning voice reminder and plays the voice message "The pipe shaft is undergoing transportation operations (which may be explained as lifting operations or lowering lifting operations), please do not approach the pipe shaft"; and before the lifting operation is started, it detects and confirms that there are no other professional operations in the area involved in the pipe shaft to ensure lifting safety.

[0123] Furthermore, a distance transmitter and a distance receiver are respectively provided at the bottom of the rectangular frame 100 and the bottom of the pipe shaft, for obtaining the operating position of the rectangular frame 100 in the pipe shaft. That is, the distance transmitter at the bottom of the rectangular frame 100 transmits a signal in real time to the distance receiver at the bottom of the pipe shaft. The distance receiver feeds the signal back to the control system, which can then determine and display the specific position of the current rectangular frame 100 in the pipe shaft on the output screen. The control system can determine the real-time lifting or lowering acceleration per unit time and the mutual sensing distance, thereby determining whether the hoisting status of the rectangular frame 100 is normal. Subsequently, the speed is increased or decreased according to the current hoisting speed.

[0124] like Figure 7 As shown, the present embodiment provides an application method of an intelligent hoisting mechanism in a shaft, comprising the following steps:

[0125] Step S0: Before the lifting operation, start the control system of the intelligent lifting mechanism and complete the following initialization work:

[0126] Confirm that the rectangular frame has been installed in the shaft and that the guide and limit structures are intact;

[0127] Confirm that the lifting platform is in the initial position, and the telescopic device of the hanging device and the hook are in an operable state;

[0128] Start the weight sensor and weightlessness monitoring module, calibrate the sensors, and ensure the accuracy of monitoring data;

[0129] Step S1: Open the door 101 or the side door 103, place the cargo to be transported on the lifting platform 501, and use the weight sensor to detect whether the cargo meets the transport weight;

[0130] Step S2: The control system adjusts the lifting hydraulic rod 502 to drive the folding frame 503 to extend and open, causing the lifting platform 501 to descend, so that the goods are embedded in the rectangular frame 100 to achieve stable transportation;

[0131] Step S3: The lifting mechanism disposed above the vertical shaft connects the hook 400 via a steel wire rope to lift the rectangular frame 100 into the narrow pipe shaft, and then lifts and transports the rectangular frame 100 from the narrow pipe shaft;

[0132] During the lifting process, a rhythm controller is provided to coordinate the movement of the upper telescopic plate 201 and the lower telescopic plate 301, so that the upper telescopic plate 201 and the lower telescopic plate 301 are alternately extended and retracted during the lifting process, thereby avoiding obstacles in the shaft and preventing the telescopic device from interfering with or colliding with the floor slab 700 or obstacles in the shaft.

[0133] At the same time, the weightlessness monitoring module obtains the value of the force applied to the hook 400 in real time and continuously transmits this data to the control system. The control system dynamically determines and analyzes the value of the force. When it detects that the force applied to the hook 400 is less than a preset safety threshold, it determines that there is an abnormality in the current lifting state. Abnormal conditions include but are not limited to the hanging object falling off, the wire rope breaking, or the cargo is about to fall.

[0134] When an abnormal situation is determined, the control system immediately issues a control command to control the upper telescopic plate 201 and the lower telescopic plate 301 to be promptly supported on the nearest floor 700 or obstacle structure in the shaft, thereby playing a blocking and limiting role, preventing the rectangular frame 100 from continuing to fall, thereby effectively preventing the risk of falling, blocking the hook or lifting platform from continuing to fall, and preventing the rectangular frame 100 from free falling, thereby ensuring operational safety;

[0135] Furthermore, when the rectangular frame suddenly loses weight or falls during the lifting process, causing the weight of the rectangular frame 100 detected by the weight sensor to change abnormally, the weight sensor feeds back the data of the abnormal change to the control system. The control system, in conjunction with the weight loss monitoring module, makes a judgment based on the weight change. The control system triggers a safety control instruction to control the upper telescopic plate 201 and the lower telescopic plate 301 to be promptly supported on the nearest floor 700 or obstacle structure in the shaft, thereby playing a blocking and limiting role, preventing the rectangular frame 100 from continuing to fall, thereby effectively preventing the risk of falling and ensuring operational safety.

[0136] Step S4: In addition, by passing the steel wire rope through the rope guide 600 outside the rectangular frame 100, additional support can be provided to prevent the rectangular frame 100 from shaking in the horizontal range during the lifting process;

[0137] Step S5: After the cargo is hoisted to the target location, the side door 103 is opened, and the lifting hydraulic rod 502 is controlled to push the folding frame 503 to extend, thereby raising the height of the lifting platform 501 so that the bottom surface of the cargo on the lifting platform is flush with the bottom surface of the side door 103;

[0138] Step S6: Adjust the lower hydraulic rod 302 so that the lower telescopic plate 301 contacts the plane of the floor 700. At this time, the slope formed by the lower telescopic plate is adjusted; guide the movement of the carried goods by the traction rope, and utilize the slope formed by the lower telescopic plate 301 to smoothly pull the goods out of the rectangular frame 100;

[0139] Step S7: Similarly, when it is necessary to lower the telescopic plate 201 and the lower telescopic plate 301 for transportation, the upper telescopic plate 201 and the lower telescopic plate 301 are also coordinated and controlled by setting a rhythm controller, so that the upper telescopic plate 201 and the lower telescopic plate 301 are alternately extended and opened and retracted and closed during the descent process, thereby avoiding obstacles in the shaft and preventing the telescopic device from interfering with or colliding with the floor 700 or obstacles in the shaft.

[0140] Also, during the hoisting process, the force value of the hook 400 is monitored by the weight loss monitoring module, and the weight of the rectangular frame 100 is detected by the weight detection sensor. When either the weight loss monitoring module or the weight detection sensor detects that the force exerted on the hook 400 is less than a preset safety threshold or the weight of the rectangular frame 100 suddenly drops, the weight loss monitoring module or the weight detection sensor or both of them work together to quickly feed back the collected force value or weight data to the control system. The control system controls and pushes the upper telescopic plate 201 and the lower telescopic plate 301 to rotate outward and open, so that they can be erected on the nearest two side floor slabs 700 in the shaft when falling, and will not continue to fall, thereby avoiding safety hazards of hoisting.

[0141] Example 2: Based on Example 1, Example 2 is based on the inconsistency or deviation in the height of the floor slabs 700 on different floors. If a rhythm controller is simply used for unified time control, the opening and closing rhythm of the upper telescopic plate 201 and the lower telescopic plate 301 may fail, posing a safety risk.

[0142] Therefore, if Figure 8 As shown, a transmitter 803 of a position sensor is provided on one side of each floor slab 700, and a pair of first receivers 801 and a pair of second receivers 802 of the position sensor are symmetrically provided on both sides of the rectangular frame 100. The pair of first receivers 801 are located above the upper telescopic plate 201, and the pair of second receivers 802 are located between the upper telescopic plate 201 and the lower telescopic plate 301. It is preset that the upper telescopic plate 201 will not hit the floor slab 700 during the telescopic movement after receiving the signals from the first receiver 801 and the second receiver 802.

[0143] The first receiver 801 and the second receiver 802 respectively cooperate with the transmitter 803 to receive signals and feed them back to the control system, thereby controlling the upper telescopic plate 201 to extend and open or retract and close.

[0144] At the same time, the control system is set to alternate between the retracted and closed states of the upper telescopic plate 201 and the lower telescopic plate 301. That is, in a preset program, when the upper telescopic plate 201 receives a signal transmitted by the transmitter 803 to the first receiver 801 or the second receiver 802, the signal is fed back to the control system. The control system controls the upper telescopic plate 201 to respectively extend and open or retract and close the state, and immediately controls the lower telescopic plate 301 to the opposite state of the upper telescopic plate 201, so that the upper telescopic plate 201 and the lower telescopic plate 301 are alternately opened, thereby ensuring that one of the telescopic plates is always in the extended and open state.

[0145] The specific steps are as follows:

[0146] like Figure 8 A rectangular frame 100 is shown as a simplified front view, which is used for Figure 10 and Figure 11 In the demonstration, in the initial state, the upper telescopic plate 201 is in the extended and open state by default.

[0147] In the transport state of lifting and hoisting, when the first receiver 801 is set to receive the signal of the transmitter 803, the control system controls the upper telescopic plate 201 to extend and open after receiving the feedback signal; when the second receiver 802 is set to receive the transmitter 803, the control system controls the upper telescopic plate 201 to retract and close after receiving the feedback signal.

[0148] like Figure 10 As shown, the lifting and hoisting is from bottom to top as shown by the arrow, which indicates the state of the lifting and hoisting demonstration. The process steps of lifting and hoisting are as follows: Figure 10 The sequence from bottom to top should also be followed. When the rectangular frame 100 is being lifted and transported, the upper telescopic plate 201 is initially in an extended open state by default, and the lower telescopic plate 301 is retracted and closed.

[0149] First, the transmitter 803 on the floor 700 triggers the first receivers 801 on both sides of the rectangular frame 100 above the upper telescopic plate 201. When the first receivers 801 receive the sensing signal from the transmitter 803 on the floor 700, the control system controls the upper telescopic plate 201 to retract and close, ensuring that it does not contact the floor 700.

[0150] When the control system detects that the upper telescopic plate 201 is in the retracted and closed state, it controls the lower telescopic plate 301 to extend and open. The rectangular frame 100 is continuously lifted and hoisted. The first receivers 801 on either side of the rectangular frame 100 separate from the transmitters 803 on the floor 700, maintaining the upper and lower telescopic plates 201 and 301 in this state until the transmitters 803 on the floor 700 trigger the second receivers 802 on either side of the rectangular frame 100. Upon receiving the sensing signal from the transmitters 803 on the floor 700, the control system controls the upper telescopic plate 201 to extend and open, and the lower telescopic plate 301 to retract and close.

[0151] Thus, the upper telescopic plate 201 and the lower telescopic plate 301 can be alternately opened and closed during the lifting process, ensuring that at least one telescopic plate is in an extended and open state at any time, thereby ensuring the safety of the vertical transportation process.

[0152] like Figure 11 As shown, the lowering hoisting is as shown by the arrow from top to bottom, indicating the status of the lowering hoisting demonstration, in which the process steps of the lowering hoisting are as follows: Figure 11 The sequence from top to bottom should also be followed. When the rectangular frame 100 is in the process of being lowered and hoisted for transportation, the upper telescopic plate 201 is initially in an extended open state by default, and the lower telescopic plate 301 is retracted and closed.

[0153] First, the transmitter 803 on the floor 700 triggers the second receiver 802. When the second receiver 802 receives the sensing signal from the transmitter 803 on the floor 700, the control system controls the upper telescopic plate 201 to retract and close, and ensures that it does not touch the floor 700.

[0154] When the control system detects that the upper telescopic plate 201 is in the retracted and closed state, it controls the lower telescopic plate 301 to extend and open. The rectangular frame 100 continues to be lowered and hoisted. The second receivers 802 on both sides of the rectangular frame 100 separate from the transmitters 803 on the floor 700, maintaining the state of the upper telescopic plate 201 and the lower telescopic plate 301 until the transmitters 803 on the floor 700 trigger the first receivers 801 on both sides of the rectangular frame 100. When the first receivers 801 receive the sensing signal from the transmitters 803 on the floor 700, the control system controls the upper telescopic plate 201 to extend and open, and the lower telescopic plate 301 to retract and close.

[0155] Thus, the upper telescopic plate 201 and the lower telescopic plate 301 can be alternately opened and closed during the lowering and hoisting process, ensuring that at least one telescopic plate is in an extended and open state at any time, thereby ensuring the safety of the vertical transportation process.

[0156] The intelligent hoisting mechanism in the shaft of this embodiment achieves high safety and stability during the hoisting process through precise control of the weightlessness monitoring module, telescopic device, and lifting platform. Its function of automatically adjusting the hoisting direction and preventing further falling, combined with the hydraulic system to accurately control the platform height, greatly improves the efficiency and accuracy of the operation. In addition, the design of the rope guide and lifting platform enhances stability and ensures the safe transportation of goods in the narrow pipe shaft. The device is versatile and flexible, capable of meeting different hoisting requirements, and solves the safety hazards and operational difficulties in hoisting operations.
