Description

Technical Field

[0001] This invention belongs to the field of well hoisting, specifically a vertical hoisting and transportation device for the inside of a well. Background Technology

[0002] With the rapid development of urban construction in my country, the hoisting of materials in pipelines and manholes has gradually gained attention. For high-rise buildings or other construction sites, hoisting equipment is needed to hoist and transport materials in manholes of all sizes.

[0003] A Chinese patent with publication number CN103243926A discloses a construction method for hoisting risers in manholes of high-rise buildings. The steps are: (1) construction preparation; (2) setting up a main hoist and an auxiliary hoist; (3) transporting the pipeline horizontally to the manhole; (4) hoisting the top section of the riser using the main hoist; (5) hoisting the second-to-last section of the riser using the auxiliary hoist; (6) aligning the two sections of the pipeline with bolts. This invention is mainly characterized by its convenient and fast operation, and can also reduce costs and increase efficiency.

[0004] When vertically hoisting and transporting materials inside the manhole, the existing transportation equipment has a relatively simple structure. When transporting materials vertically downward inside the manhole, it is easy for them to collide and rub against the manhole wall, which makes the transportation of goods extremely unstable and may even cause a small amount of goods to fall off.

[0005] Therefore, the present invention provides a vertical hoisting and transportation device for inside a well. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A vertical hoisting and transportation device for inside a well, comprising a transport platform; four sets of sliding blocks are slidably connected to the inner sidewall of the transport platform; a rotating shaft is rotatably connected to the inner sidewall of each sliding block; a pulley is fixedly connected to the sidewall of the rotating shaft; multiple sets of elastic columns are fixedly connected to the inner sidewall of the transport platform, and one end of each elastic column is fixedly connected to the sidewall of the sliding block; a transmission assembly is provided on the sidewall of each sliding block for sliding; a fixing mechanism is provided at the top of the transport platform for suspension and hoisting; during vertical hoisting… The crane is connected to the fixing mechanism on the transport platform, and the transported materials are placed in the central groove of the transport platform. With the assistance of the fixing mechanism, four sets of sliding blocks are slid outwards using the transmission component. The sliding blocks drive multiple sets of pulleys to support the manhole wall. As the transport platform is lowered by the crane, the pulleys slowly rotate on the manhole wall, which plays a role in smooth descent, reducing friction and collision between the materials and the manhole wall, and reducing the occurrence of materials falling. The elastic column plays a role in pulling the sliding blocks back to their original position. At the same time, the sliding blocks slide with the transmission component, which plays a role in adapting to the size of the manhole diameter.

[0008] Preferably, the transmission assembly includes a connecting rod, a sliding pressure plate, and an electric cylinder; the connecting rod is rotatably connected to the top of the sliding block; the sliding pressure plate is rotatably connected to the side wall of the connecting rod; the electric cylinder is fixedly connected inside the transport platform, and the output end of the electric cylinder is fixedly connected to the top of the sliding pressure plate; a support frame is fixedly connected to the bottom end of the sliding pressure plate; when the four sets of sliding blocks slide, they drive the pulleys to support the well wall, and cooperate with the lowering of the crane to slide down steadily and slowly, achieving the effect of smoothly transporting materials. The support frame is used to support the materials when they fall to the bottom of the well, and when the materials are lowered to the bottom of the well, the output end of the electric cylinder retracts, and cooperates with the elastic column to pull the sliding blocks to slide into the transport platform, driving the four sets of sliding blocks to retract into the transport platform, achieving the effect of storage.

[0009] Preferably, the transport platform has multiple sets of air-injection slots inside; a connecting plate is fixedly connected to the top of the sliding block, and the connecting plate is located at the air-injection slot; a fixing frame is fixedly connected to the side wall of the connecting plate; a reinforced nylon cloth is fixedly connected to the inner side wall of the fixing frame; a wind speed sensor is fixedly connected to the inner side wall of the transport platform and is located inside the air-injection slot; the wind during inertial descent is injected into the air-injection slot inside the transport platform to buffer the descent, and at the same time, the wind speed sensor monitors the amount of air injected, thereby determining whether there is any abnormality in the hoisting operation. When the wind force exceeds the set value, an alarm is issued to reduce the occurrence of safety hazards, and when the sliding block retracts, it drives the fixing frame to be retracted into the transport platform, achieving a storage effect.

[0010] Preferably, a limit block is fixedly connected to the side wall of the rotating shaft; a follower plate is provided on the side wall of the rotating shaft; a mating toothed plate is fixedly connected inside the sliding block, and the inner side wall of the mating toothed plate is provided with multiple sets of teeth corresponding to the grooves on the side wall of the follower plate; the follower plate shakes and rotates rapidly, and the corresponding teeth on the mating toothed plate engage with the grooves on the side wall of the follower plate, achieving an emergency braking effect, similar to the principle of a car seat belt. When the pulley slowly falls with the crane, the follower plate will not jam with the mating toothed plate, which is used in conjunction with reinforced nylon cloth to further reduce the occurrence of accidents.

[0011] Preferably, the fixing mechanism includes a fixed handle, a compression plate, a square plate, an air guide tube, and a clamping assembly; the fixed handle is fixedly connected to the top of the transport platform, and there are two sets of fixed handles; the compression plate is slidably connected to the inner wall of the fixed handle; the square plate is fixedly connected to the bottom end of the compression plate; the air guide tube is fixedly connected inside the fixed handle; the clamping assembly is located inside the transport platform and is used to clamp and stabilize the materials; the two support points are used for suspension to enhance the stability effect and reduce obstruction of the material placement space. At the same time, when suspended, the connecting rope presses the compression plate on the square plate to slide due to the weight of the materials and the transport platform. The compression plate compresses the gas in the cavity inside the fixed handle and conducts it to the clamping assembly through the air guide tube, which works in conjunction with the clamping assembly to fix the materials.

[0012] Preferably, the conveying platform has an internal compression groove, and the clamping assembly includes a sliding plate, a clamping plate, and an elastic element. The sliding plate is slidably connected to the inner side wall of the conveying platform and is located at the compression groove. The clamping plate is fixed to the side wall of the sliding plate. The elastic element is fixed to the inner side wall of the conveying platform, and one end of the elastic element is fixed to the side wall of the sliding plate. One end of the air guide pipe is connected to the compression groove inside the conveying platform. The compression groove drives two sets of sliding plates to move towards and clamp the material. Together with the clamping plate and the soft pad on the side wall, the material is clamped to the side wall, which can fix the material and enhance the stability during transportation. When the material falls to the bottom of the well, the suspension force of the crane's connecting rope disappears, and the elastic element pulls the sliding plate to slide into the interior of the conveying platform, which can realize the function of receiving the sliding plate and driving the square plate to return to its original position.

[0013] Preferably, a first iron plate is fixedly connected to the bottom end of the square plate; a second iron plate is fixedly connected to the bottom end of the square plate; the first and second iron plates are symmetrically arranged and are semi-circular in shape; a rubber block is fixedly connected to the bottom end of the square plate and is located between the first and second iron plates; by fixing the first and second iron plates to the bottom end of the square plate respectively, multiple strands of connecting rope are inserted into the gap between the first and second iron plates, and the rubber block compresses the multiple strands of connecting rope, which has an anti-slip effect on the connecting rope and reduces the problem of material shaking caused by the slippage of the connecting rope during suspension. At the same time, the cooperation and compression between the first and second iron plates has a limiting and anti-detachment effect on the connecting rope.

[0014] Preferably, a first magnetic block is fixedly connected inside the first iron plate; a second magnetic block is fixedly connected inside the second iron plate; the first and second magnetic blocks can attract each other when they are close to each other; the magnetic attraction between the first and second magnetic blocks improves the tightness between the side walls of the first and second iron plates and enhances the limiting effect on the connecting rope.

[0015] Preferably, multiple sets of anti-slip protrusions are fixed to the side walls of both the No. 1 and No. 2 iron plates; multiple sets of anti-slip protrusions are fixed to the bottom end of the rubber block; the multiple sets of anti-slip protrusions are fixed to the side walls of the No. 1 iron plate, No. 2 iron plate and the rubber block respectively, so as to achieve the anti-slip effect on the single strand connecting rope and increase the friction area.

[0016] Preferably, a friction sleeve is fitted onto the side wall of the pulley; multiple sets of friction protrusions are fixed to the side wall of the friction sleeve; the multiple sets of friction protrusions are connected through multiple sets of vent pipes; by wrapping the friction sleeve around the outer side wall of the pulley, the tightness between the pulley and the well wall is improved, and by using multiple sets of friction protrusions in conjunction with the vent pipes in series, the friction area when the pulley slides is further increased, which enhances the stability. At the same time, by wrapping the pulley, the friction of the pulley is reduced, and the service life of the pulley is slowed down.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention discloses a vertical hoisting and transportation device for inside a manhole. Through a set transportation platform, when vertically transporting materials to the manhole, the materials are placed on the transportation platform and supported by four sets of pulleys on the manhole wall. As the crane slowly lowers, the materials slide, achieving stable transportation. The output end of an electric cylinder extends to control the pulleys supporting the manhole wall, and retracts them into the transportation platform for storage during retraction, thus adapting to the manhole diameter and facilitating retraction. When the crane connecting rope breaks, reinforced nylon cloth is used to inject air into the air-injection groove inside the transportation platform, providing a buffering effect. An alarm signal is issued in conjunction with a wind speed sensor to reduce safety hazards. Finally, a follower plate jams against the mating toothed plate due to excessive descent speed, achieving an emergency braking effect.

[0019] 2. The vertical hoisting and transportation equipment inside a well as described in this invention uses two sets of fixed handles to connect the connecting rope of the crane and insert the connecting rope between the first iron plate and the second iron plate. With the compression of the rubber block, the connecting rope is limited. When lowering, the connecting rope presses the extrusion plate to compress the air inside the fixed handle. The air guide pipe conducts the air to the extrusion groove, squeezing out the two sets of sliding plates. With the help of the clamping plate and soft pad, the materials are clamped, enhancing the stability of the materials during lowering. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1 to 2As shown in the embodiment of the present invention, a vertical hoisting and transportation device inside a well includes a transport platform 1; four sets of sliding blocks 11 are slidably connected to the inner wall of the transport platform 1; a rotating shaft 12 is rotatably connected to the inner wall of the sliding block 11; a pulley 13 is fixedly connected to the side wall of the rotating shaft 12; multiple sets of elastic columns 14 are fixedly connected to the inner wall of the transport platform 1, and one end of the elastic column 14 is fixedly connected to the side wall of the sliding block 11; a transmission assembly is provided on the side wall of the sliding block 11 for sliding use; a fixing mechanism is provided at the top of the transport platform 1 for suspension hoisting; when vertically hoisting and transporting materials inside a well, due to the relatively simple structure of existing transportation equipment, materials are easily subjected to collisions and friction with the well wall when vertically transporting materials downward inside the well. This friction can lead to instability during cargo transportation, even causing some goods to fall off. Therefore, during vertical hoisting, the crane is connected to the fixing mechanism on the transport platform 1, and the transported materials are placed in the central groove of the transport platform 1. The fixing mechanism assists in securing the materials. The transmission assembly is used to slide four sets of sliding blocks 11 to the outside of the transport platform 1. The sliding blocks 11 drive multiple sets of pulleys 13 to support the manhole wall. When the transport platform 1 is lowered by the crane, the pulleys 13 slowly rotate on the manhole wall, which plays a role in smooth descent, reducing friction and collision between the materials and the manhole wall, and reducing the occurrence of materials falling off. The elastic column 14 plays a role in pulling the sliding blocks 11 back to their original position. At the same time, the sliding blocks 11 slide with the transmission assembly to achieve an adaptive effect to the diameter of the manhole.

[0030] The transmission assembly includes a connecting rod 2, a sliding pressure plate 21, and an electric cylinder 22. The connecting rod 2 is rotatably connected to the top of the sliding block 11. The sliding pressure plate 21 is rotatably connected to the side wall of the connecting rod 2. The electric cylinder 22 is fixedly connected inside the transport platform 1, and the output end of the electric cylinder 22 is fixedly connected to the top of the sliding pressure plate 21. A support frame 23 is fixedly connected to the bottom end of the sliding pressure plate 21. When the transport platform 1 carries materials down into the well, a crane is used to suspend the transport platform 1 inside the well. The output end of the electric cylinder 22 slides down, causing the sliding pressure plate 21 to slide downwards during transport. The inner wall of platform 1 simultaneously drives the sliding blocks 11, which are hinged together by connecting rod 2, to slide outwards from the transport platform 1. When the four sets of sliding blocks 11 slide, they drive the pulleys 13 to support the well wall. With the lowering of the crane, they slide down steadily and slowly, achieving the effect of smooth material transport. The support frame 23 is used to support the materials when they fall to the bottom of the well. When the materials are lowered to the bottom of the well, the output end of the electric cylinder 22 retracts, and with the elastic column 14, it pulls the sliding blocks 11 to slide inwards from the transport platform 1, driving the four sets of sliding blocks 11 to retract into the transport platform 1, achieving the effect of storage.

[0031] The transport platform 1 has multiple sets of air-injection slots inside; the top of the sliding block 11 is fixedly connected to a connecting plate 3, and the connecting plate 3 is located at the air-injection slot; the side wall of the connecting plate 3 is fixedly connected to a fixing frame 31; the inner side wall of the fixing frame 31 is fixedly connected to a reinforced nylon cloth 32; the inner side wall of the transport platform 1 is fixedly connected to a wind speed sensor 33, which is located inside the air-injection slot; when the connecting rope suspended by the crane breaks after prolonged use, the sliding block 11 slides down at the output end of the electric cylinder 22, causing the multiple sets of connecting plates 3 to slide inside the transport platform 1. The reinforced nylon cloth 32 on the fixing frame 31 stores wind like a hot air balloon, injecting the wind during inertial descent into the air-injection slot inside the transport platform 1, thus buffering the descent. At the same time, the wind speed sensor 33 monitors the amount of wind injected, thereby determining whether there is any abnormality in the hoisting operation. When the wind force exceeds the set value, an alarm is issued to reduce the occurrence of safety hazards. Furthermore, when the sliding block 11 retracts, it causes the fixing frame 31 to retract into the transport platform 1, achieving a storage effect.

[0032] like Figures 1 to 3 As shown, a limiting block 4 is fixedly connected to the side wall of the rotating shaft 12; a follower plate 41 is provided on the side wall of the rotating shaft 12; a mating toothed plate 42 is fixedly connected inside the sliding block 11, and multiple sets of teeth corresponding to the grooves on the side wall of the follower plate 41 are provided on the inner side wall of the mating toothed plate 42; when the connecting rope of the crane breaks after long-term use, the transport platform 1 falls rapidly, and the four sets of pulleys 13 rotate against the well wall, driving the limiting block 4 on the side wall of the rotating shaft 12 to rotate. At the same time, the follower plate 41 shakes and rotates rapidly, and the corresponding teeth on the mating toothed plate 42 engage with the grooves on the side wall of the follower plate 41, achieving an emergency braking effect, similar to the principle of a car seat belt. When the pulleys 13 fall slowly with the crane, the follower plate 41 will not jam with the mating toothed plate 42, and is used in conjunction with the reinforced nylon cloth 32 to further reduce the occurrence of accidents.

[0033] like Figures 1 to 4 As shown, the fixing mechanism includes a fixed handle 5, a pressing plate 51, a square plate 52, an air guide pipe 53, and a clamping assembly. The fixed handle 5 is fixedly connected to the top of the transport platform 1, and there are two sets of fixed handles. The pressing plate 51 is slidably connected to the inner wall of the fixed handle 5. The square plate 52 is fixedly connected to the bottom end of the pressing plate 51. The air guide pipe 53 is fixedly connected inside the fixed handle 5. The clamping assembly is set inside the transport platform 1 and is used to clamp and stabilize materials. When the crane is connected to the transport platform 1 using a connecting rope, the connecting rope passes through the two sets of fixed handles 5 respectively, and is suspended using two support points to enhance the stability effect and reduce the obstruction of the material placement space. At the same time, when suspended, the connecting rope presses the pressing plate 51 on the square plate 52 to slide due to the weight of the materials and the transport platform 1. The pressing plate 51 compresses the gas in the cavity inside the fixed handle 5 and conducts it to the clamping assembly through the air guide pipe 53, which is linked with the clamping assembly to achieve the effect of fixing the materials.

[0034] The conveying platform 1 has an internal compression groove. The clamping assembly includes a sliding plate 6, a clamping plate 61, and an elastic element 62. The sliding plate 6 is slidably connected to the inner wall of the conveying platform 1 and is located at the compression groove. The clamping plate 61 is fixed to the side wall of the sliding plate 6. The elastic element 62 is fixed to the inner wall of the conveying platform 1, and one end of the elastic element 62 is fixed to the side wall of the sliding plate 6. One end of the air guide pipe 53 communicates with the compression groove inside the conveying platform 1. When materials are placed in the groove at the top of the conveying platform 1, a crane is used to... The connecting rope for suspending materials presses the squeezing plate 51 to compress the gas inside the fixed handle 5. The gas is then transmitted to the squeezing chute through the air guide pipe 53. The squeezing chute drives two sets of sliding plates 6 to move closer to the materials and clamp them. Together with the clamping plate 61 and the soft pads on the side wall, the materials are clamped to the side wall, which can fix the materials and enhance the stability during transportation. When the materials fall to the bottom of the well, the suspension force of the crane's connecting rope disappears, and the elastic element 62 pulls the sliding plate 6 to slide into the inside of the transport platform 1, which can realize the function of storing the sliding plate 6 and driving the square plate 52 to reset.

[0035] like Figures 2 to 4 As shown, a first iron plate 7 is fixed to the bottom end of the square plate 52; a second iron plate 71 is fixed to the bottom end of the square plate 52; the first iron plate 7 and the second iron plate 71 are symmetrically arranged and are semi-circular in shape; a rubber block 72 is fixed to the bottom end of the square plate 52 and is located between the first iron plate 7 and the second iron plate 71; when the connecting rope of the crane passes through the fixed handle 5 for connection, in order to reduce the impact of slippage of the connecting rope when suspended through the fixed handle 5, the first iron plate 7 and the second iron plate 71 are fixed to the bottom end of the square plate 52 respectively, and the multiple strands of connecting rope are inserted into the gap between the first iron plate 7 and the second iron plate 71, and the rubber block 72 is used to squeeze the multiple strands of connecting rope to achieve the effect of anti-slip of the connecting rope, reducing the problem of material shaking caused by the slippage of the connecting rope during suspension. At the same time, the cooperation and squeezing between the first iron plate 7 and the second iron plate 71 achieves the effect of limiting and preventing the connecting rope from falling off.

[0036] A first magnetic block 8 is fixedly connected inside the first iron plate 7; a second magnetic block 81 is fixedly connected inside the second iron plate 71; the first magnetic block 8 and the second magnetic block 81 can attract each other when they are close to each other; when the connecting rope is hung between the first iron plate 7 and the second iron plate 71, in order to prevent the connecting rope from coming out, the magnetic attraction between the first magnetic block 8 and the second magnetic block 81 is used to improve the tightness between the side walls of the first iron plate 7 and the second iron plate 71, and enhance the limiting effect on the connecting rope.

[0037] Multiple sets of anti-slip protrusions 9 are fixed to the side walls of both the No. 1 iron plate 7 and the No. 2 iron plate 71; multiple sets of anti-slip protrusions 9 are fixed to the bottom end of the rubber block 72; when a single strand of the connecting rope is hung between the No. 1 iron plate 7 and the No. 2 iron plate 71, in order to reduce the multiple slippage of the single strand of the connecting rope between the No. 1 iron plate 7 and the No. 2 iron plate 71, multiple sets of anti-slip protrusions 9 are fixed to the side walls of the No. 1 iron plate 7, the No. 2 iron plate 71 and the rubber block 72 respectively, so as to achieve the anti-slip effect on the single strand of the connecting rope and increase the friction area.

[0038] Example 2

[0039] like Figure 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a friction sleeve 91 is sleeved on the side wall of the pulley 13; multiple sets of friction protrusions 92 are fixedly connected to the side wall of the friction sleeve 91; the multiple sets of friction protrusions 92 are connected through multiple sets of vent pipes 93; when the transport platform 1 is lowered by the crane, multiple sets of pulleys 13 are supported on the well wall. In order to enhance the tightness of the fit between the pulley 13 and the well wall, the friction sleeve 91 is wrapped around the outer side wall of the pulley 13 to improve the tightness between the pulley 13 and the well wall. The multiple sets of friction protrusions 92 are connected in series with the vent pipes 93 to further increase the friction area when the pulley 13 slides, thereby enhancing the stability. At the same time, the wrapping of the friction sleeve 91 reduces the friction of the pulley 13 and slows down the service life of the pulley 13.

[0040] Working principle: When vertically hoisting and transporting materials inside a manhole, existing transportation equipment has a relatively simple structure. When transporting materials vertically downwards within the manhole, collisions and friction with the manhole wall are likely to occur, leading to extreme instability during transport and even causing some goods to fall off. Therefore, during vertical hoisting, the crane is connected to the fixing mechanism on the transport platform 1, and the transported materials are placed in the central groove of the transport platform 1. With the assistance of the fixing mechanism, four sets of sliding blocks 11 are slid outwards using a transmission assembly. The sliding blocks 11 drive multiple sets of pulleys 13 to support the manhole wall. As the transport platform 1 is lowered by the crane, the pulleys 13 slowly rotate on the manhole wall, ensuring a smooth descent. To reduce friction and collision between materials and the well wall, thus minimizing material falling, the elastic column 14 pulls the sliding block 11 back to its original position. Simultaneously, the sliding block 11 slides with the transmission assembly, adapting to the well diameter. When the transport platform 1 carries materials down into the well, a crane suspends it inside the well. The output end of the electric cylinder 22 slides down, causing the sliding pressure plate 21 to slide downwards against the inner wall of the transport platform 1. Simultaneously, the sliding blocks 11, hinged together by the connecting rod 2, slide outwards. As the four sets of sliding blocks 11 slide, the pulleys 13 support the well wall, facilitating a stable and slow descent with the crane's lowering, ensuring smooth material transport. (Support frame) 23 is used for support when materials are lowered to the bottom of the well. When materials are lowered to the bottom of the well, the output end of the electric cylinder 22 retracts, and in conjunction with the elastic column 14, pulls the sliding block 11 to slide into the transport platform 1, causing the four sets of sliding blocks 11 to retract into the transport platform 1, achieving a storage effect. When the connecting rope suspended by the crane breaks after prolonged use, the sliding block 11 slides down at the output end of the electric cylinder 22, causing multiple sets of connecting plates 3 to slide inside the transport platform 1. The reinforced nylon cloth 32 on the fixing frame 31 stores wind like a hot air balloon, and injects the wind during inertial descent into the air-injection groove inside the transport platform 1, achieving a buffering effect. At the same time, the wind speed sensor 33 monitors the amount of air injected, thereby determining whether there is any abnormality in the hoisting operation. An alarm is triggered when the wind force exceeds the set value, reducing the occurrence of safety hazards. When the sliding block 11 retracts, it drives the fixed frame 31 to be retracted into the transport platform 1, achieving a storage effect. When the connecting rope of the crane breaks after prolonged use, the transport platform 1 falls rapidly. The four sets of pulleys 13 rotate against the wall of the manhole, driving the limit block 4 on the side wall of the rotating shaft 12 to rotate. At the same time, the follower plate 41 shakes and rotates rapidly. The corresponding teeth on the toothed plate 42 engage with the groove on the side wall of the follower plate 41, achieving an emergency braking effect, similar to the principle of a car seat belt. When the pulley 13 falls slowly with the crane, the follower plate 41 will not jam with the toothed plate 42. It is used in conjunction with the reinforced nylon cloth 32 to further reduce the occurrence of accidents.When the crane is connected to the transport platform 1 using a connecting rope, the connecting rope passes through two sets of fixed handles 5, using two support points for suspension, enhancing stability and reducing obstruction of the material placement space. Simultaneously, during suspension, the weight of the material and the transport platform 1 causes the squeezing plate 51 on the square plate 52 to slide. The squeezing plate 51 compresses the gas inside the fixed handle 5 and transmits it through the air guide pipe 53 to the clamping assembly, creating a linkage with the clamping assembly and securing the material. When the material is placed in the groove at the top of the transport platform 1, the crane suspends... The connecting rope for hoisting materials presses against the compression plate 51, squeezing the gas inside the fixed handle 5. This gas is then transmitted through the air guide pipe 53 to the compression chute. The compression chute causes two sets of sliding plates 6 to move closer to and clamp the materials. Together with the clamping plates 61 and the soft pads on the side walls, they clamp the materials, securing them and enhancing stability during transport. When the materials fall to the bottom of the well, the suspension force of the hoist's connecting rope disappears, and the elastic element 62 pulls the sliding plates 6 into the transport platform 1, effectively storing the sliding plates 6 and resetting the square plate 52. When the hoist's connecting rope passes through the fixed handle 5... During connection, to reduce the impact of slippage when the connecting rope passes through the fixed handle 5, iron plates 7 and 71 are fixed to the bottom of the square plate 52. Multiple strands of the connecting rope are inserted into the gap between iron plates 7 and 71, and rubber blocks 72 compress the rope to prevent slippage and reduce material shaking caused by rope slippage during suspension. Simultaneously, the compression between iron plates 7 and 71 also helps to limit and prevent the connecting rope from detaching. When the connecting rope is hooked into iron plates 7 and 71... When the connecting rope is between plates 71, to prevent it from coming loose, the magnetic attraction between magnetic block 8 and magnetic block 81 is used to improve the tightness between the side walls of plates 71 and 81, thus enhancing the limiting effect on the connecting rope. When a single strand of the connecting rope is hooked between plates 71 and 81, to reduce the multiple slippages of the single strand between plates 71 and 81, multiple sets of anti-slip protrusions 9 are fixed to the side walls of plates 71, 81 and 81, and rubber block 72, respectively, to prevent the single strand of the connecting rope from slipping and to increase the friction area.
