Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building construction, and particularly relates to a detachable hoist bucket and a material transfer method for high-rise building construction. BACKGROUND

[0002] With the vigorous development of market economy, urban land resources are increasingly scarce, and many high-rise buildings have been erected. In actual engineering construction, tower cranes are increasingly used, and as the height of buildings is increasingly high, tower cranes are needed to hoist and transfer some materials.

[0003] At present, the hoist bucket commonly used in construction sites is a self-made steel bucket, which is mainly used to transfer small components in the building construction process, such as fasteners, top supports, bottom supports, and small temporary electrical equipment. However, such a bucket has low efficiency, especially when it comes to indoor material transfer, such as adding blocks, installing sleeves, and transferring floor garbage. The bucket needs to be placed on the unloading platform before unloading, and the unloading needs to separate the hook of the tower crane from the bucket, unload the materials in the bucket to the unloading platform, and then reconnect the hook of the tower crane to the bucket. The entire unloading process needs to occupy the floor unloading platform for a long time, and cannot continuously transfer materials, which requires manual loading and unloading of materials multiple times, reducing the efficiency of tower crane material transfer and consuming a large amount of labor.

[0004] Therefore, it is necessary to provide a detachable hoist bucket that can not only reduce the occupation of the floor unloading platform, but also improve the efficiency of tower crane material transfer and reduce labor. SUMMARY

[0005] The present application aims to overcome the shortcomings of the prior art and provide a detachable hoist bucket and a material transfer method for high-rise building construction to solve the problem of low efficiency of material hoisting and transfer for high-rise building construction.

[0006] In the first aspect, the present application provides a detachable hoist bucket, comprising:

[0007] An outer hoist bucket having an upper end provided with a hoist rope for cooperating with the hook of a tower crane; at least one material access opening is arranged at the side end of the outer hoist bucket;

[0008] At least one inner bucket enters or exits the outer hoist bucket through the material access opening, and the inner bucket comprises a loading bucket for loading materials; and

[0009] A limiting and guiding assembly comprising a limiting member and a guided member; the limiting member comprises a limiting groove arranged in the horizontal direction on the side wall of the outer hoist bucket and communicating with the material access opening; and the guided member is arranged on the side wall of the inner bucket and moves in cooperation with the limiting groove to limit and guide the movement trajectory of the inner bucket.

[0010] Further, the guiding member comprises a rotating wheel, which is in rotating cooperation with the limiting groove.

[0011] By setting the rotating wheel as the guiding member, which is in rotating cooperation with the limiting groove, the inner bucket is facilitated to move along the horizontal direction.

[0012] Further, the guiding member comprises a horizontally arranged first steel belt; the limiting member comprises two horizontally arranged second steel belts, which are parallel to each other along the height direction of the outer hoist bucket and are kept apart to form the limiting groove; and the first steel belt is located between the two second steel belts.

[0013] By setting the first steel belt between the two second steel belts, the movement track of the first steel belt is limited by the second steel belts, which not only limits and guides the movement track of the inner bucket, but also, compared with the rotating wheel as the guiding member, the structural characteristics of the first steel belt and the second steel belts make the limiting and guiding assembly have a longer service life and lower maintenance cost.

[0014] Further, the two second steel belts are apart from each other at one end close to the material inlet and outlet to form a flared portion.

[0015] By setting the flared portion at one end close to the material inlet and outlet, the first steel belt is facilitated to enter between the two second steel belts, the inner bucket is facilitated to enter the outer hoist bucket, and the cooperation efficiency of the outer hoist bucket and the inner bucket and the material hoisting efficiency are improved.

[0016] Further, the two second steel belts are close to each other at one end away from the material inlet and outlet to form a tapered portion.

[0017] By setting the tapered portion at one end away from the material inlet and outlet, when the inner bucket enters the outer hoist bucket, the first steel belt is clamped by the second steel belts, which ensures the stable connection of the inner bucket and the outer hoist bucket and avoids the shaking of the inner bucket in the outer hoist bucket during the hoisting process.

[0018] Further, the limiting and guiding assembly further comprises a traction member, which is connected with the inner bucket and is used to pull the inner bucket to enter or leave the outer hoist bucket.

[0019] By pulling the inner bucket to enter or leave the outer hoist bucket through the traction member, the labor intensity is reduced. When multiple inner buckets are arranged in the outer hoist bucket, the traction member can guide multiple inner buckets to enter or leave the outer hoist bucket in an orderly manner, which improves the cooperation efficiency of the inner bucket and the outer hoist bucket and the material transfer efficiency.

[0020] Further, the traction member comprises a winch and a traction rope, one end of the traction rope is wound around the winch, and the other end of the traction rope is separably connected with the inner bucket.

[0021] The inner bucket is driven into or out of the outer bucket by the traction force provided by the winch and the traction rope, and is suitable for transferring heavy materials.

[0022] Further, the traction member comprises a telescopic pull rod, one end of the telescopic pull rod is provided with a handle, and the other end of the telescopic pull rod is rotationally connected with the inner bucket.

[0023] The telescopic pull rod not only drives the inner bucket into or out of the outer bucket, but also facilitates the traction of the inner bucket in the material yard or the unloading platform, and is more convenient and flexible to use.

[0024] Further, the traction member comprises a traction motor and a traction wheel, the traction motor drives the traction wheel to rotate, the traction motor is arranged on the side wall of the inner bucket, and the traction wheel is located in the limiting groove and rotationally matched with the limiting groove.

[0025] Further, the traction wheel comprises a traction gear, a rack engaged with the traction gear is arranged in the limiting groove, and the rack is fixed on the side wall of the outer bucket. Through the cooperation of the traction gear and the rack, the movement trajectory of the inner bucket can be limited and guided, the inner bucket can be stopped at any position during movement, and the anti-skid and anti-shaking effects are good, thereby improving the safety.

[0026] Further, the limiting and guiding assembly further comprises a plurality of electromagnets arranged along the length direction of the limiting groove, and the guided member comprises a magnet magnetically attracted and / or repulsively matched with the electromagnets. The electromagnets are further electrically connected with an electric control device, the electric control device is arranged in the outer bucket, the magnetism and magnetic force of each electromagnet are controlled through the electric control device, and this part can be realized by using the existing technology. The magnet can be arranged in the limiting groove, and the electromagnets can be distributed in the top and bottom of the limiting groove in the horizontal direction. Under the action of the electromagnets, the magnet is driven to move along the length direction of the limiting groove. When the outer bucket is provided with two material exits, one of the material exits is used for entering the inner bucket, and the other material exit is used for leaving the inner bucket, and the two ends of the limiting groove are respectively communicated with the two material exits. The continuous entry and exit of the inner bucket in the outer bucket is realized, the loading and unloading efficiency is improved, and the cooperation of the electromagnets and the magnet further improves the continuity of the entry and exit of the inner bucket.

[0027] Further, the side end of the outer bucket is further provided with a ramp plate for closing or opening the material exit; the ramp plate is rotationally connected with the bottom end of the material exit, and is used for providing a ramp for the inner bucket to enter or leave the outer bucket.

[0028] The ramp plate can be used not only to close the material access, ensure the side end of the outer bucket to be closed, and improve the construction safety, but also to provide a ramp for the inner bucket to enter or leave the outer bucket after the material access is opened, so that the inner bucket is prevented from being stuck in the gap between the unloading platform and the floor when the inner bucket moves.

[0029] In a second aspect, the present application provides a material transfer method for high-rise building construction, which utilizes the detachable bucket and the tower crane to transfer materials, and comprises the following steps:

[0030] In step 1, the outer bucket with the empty inner bucket is lifted to the material yard by the hook of the tower crane and the lifting rope of the outer bucket, at least one empty inner bucket in the outer bucket is guided to leave the outer bucket by the limiting guide assembly, the empty inner bucket is pulled to the material stacking point of the material yard, the target material of the material stacking point is loaded into the loading bucket of the empty inner bucket, and a full load inner bucket is formed.

[0031] In step 2, at least one full load inner bucket of the material yard is guided into the outer bucket parked in the material yard in step 1 by the limiting guide assembly.

[0032] In step 3, the outer bucket with the full load inner bucket in step 2 is lifted to the unloading platform of the target floor of the high-rise building by the tower crane, the full load inner bucket is guided to leave the outer bucket by the limiting guide assembly, the target material in the full load inner bucket is unloaded to the unloading platform, an empty inner bucket is formed, and at least one empty inner bucket at the same target floor is guided into the outer bucket.

[0033] In step 4, steps 1-3 are repeated until the target material is stacked on the unloading platform of all target floors of the high-rise building.

[0034] The present application has the following advantages:

[0035] By loading the material by the inner bucket and cooperating the outer bucket with the hook of the tower crane, the outer bucket does not need to be unbuckled from the hook of the tower crane during the material transfer of the detachable bucket, and other inner buckets at the material yard or the unloading platform can simultaneously load or unload the target material during the transfer of the outer bucket by the tower crane, so that the waiting time of the outer bucket at the material yard or the unloading platform is shortened, the transfer frequency of the tower crane is increased, and the material transfer efficiency is improved.

[0036] Limiting and guiding components restrict and guide the movement trajectory of the inner dump truck within the outer bucket, ensuring it enters and exits the outer bucket along a preset path. This prevents the inner dump truck from swaying or moving in unnecessary directions, guaranteeing construction safety and efficiency. Especially when the unloading platform is long and narrow, if the movement trajectory of the inner dump truck deviates from the sides of the platform when leaving the outer bucket, it can easily cause the inner dump truck or its loaded material to detach from the unloading platform, leading to a safety accident.

[0037] Compared to traditional hoisting buckets, which require frequent handling of materials inside and outside the bucket by operators, the detachable hoisting bucket of this invention loads or unloads materials through the loading bucket of the inner bucket. Then, the inner bucket is guided into or out of the outer hoisting bucket by a limiting and guiding component. This transforms the traditional hoisting bucket's handling and loading / unloading into the inner bucket's moving device or unloading, which improves efficiency, reduces labor consumption, and saves manpower.

DETAILED DESCRIPTION

[0050] The present application will be further described in detail below in conjunction with the accompanying drawings and specific examples.

[0051] As shown in Figure 1 , 2 The separable bucket of the present application comprises an outer bucket 10, an inner trolley 20, and a limiting guide component 30.

[0052] The outer bucket 10 is provided with a rope 12 at its upper end for cooperating with the hook of the tower crane; at least one material access 11 is arranged at the side end of the outer bucket 10. The outer bucket 10 comprises a bottom plate and a side plate arranged around the bottom plate, and the bottom plate and the side plate are welded and fixed to form a compartment structure with an open top end. The material access 11 is arranged on the side plate, or one or more side ends of the outer bucket 10 are not provided with a side plate, and the side end without the side plate constitutes the material access 11. Of course, in some embodiments, the outer bucket 10 can also be provided with a cover plate to close the open top end of the compartment structure. In some embodiments, the side plate of the outer bucket 10 can be replaced by several steel pipes arranged transversely, vertically and obliquely to save materials and reduce weight, and in addition, it is also convenient for the arrangement or disassembly of the traction rope 372. Four lifting lugs 13 are uniformly arranged at the top end or the side end of the outer bucket 10, and the lifting lugs 13 are connected with the rope 12. The rope 12 is connected with the hook of the tower crane. Compared with the conventional bucket which needs to be frequently unbound from the hook of the tower crane in order to facilitate the loading or unloading of the bucket, the use of the separable bucket cooperating with the tower crane for material transfer in the present embodiment does not need to unbind the hook of the tower crane from the rope 12 of the outer bucket 10, which significantly improves the efficiency of material transfer. It should be noted that the conventional bucket must be separated from the hook of the tower crane when the bucket is loading or unloading materials, otherwise the hook above the bucket is not conducive to the loading or unloading of materials.

[0053] The inner bucket 20 enters or exits the outer bucket 10 through the material access 11, and the inner bucket 20 comprises a loading bucket 21 for loading materials. In order to improve the efficiency of material transfer, there are actually multiple inner buckets 20, which can be distributed in the material yard, the unloading platform and the outer bucket 10 respectively. Among them, there can be only one or multiple inner buckets 20 in the outer bucket 10. The loading bucket 21 of the inner bucket 20 can also have multiple or only one. The inner bucket 20 comprises a base plate and a side plate arranged around the base plate. One of the side plates can be arranged in an inclined manner. Four casters 22 are arranged at the bottom corners of the base plate, and the movement of the inner bucket 20 is realized under the action of the casters 22.

[0054] The limiting and guiding assembly 30 comprises a limiting piece 31 and a guided piece 33; the limiting piece 31 comprises a limiting groove 32, which is arranged on the side wall of the outer bucket 10 in the horizontal direction and communicates with the material access 11, and the limiting groove 32 is preferably arranged on the side wall on both sides of the material access 11. The guided piece 33 is arranged on the side wall of the inner bucket 20 and moves in cooperation with the limiting groove 32 to limit and guide the movement track of the inner bucket 20. The guided piece 33 moves in the limiting groove 32, and the limiting groove 32 limits the movement track of the guided piece 33 so that it can only move in the length direction of the limiting groove 32.

[0055] In some embodiments, as Figure 3 ,4 As shown, the guided member 33 includes a rotating wheel 34 which is rotationally matched with the limiting groove 32. By setting the rotating wheel 34 as the guided member 33, which is rotationally matched with the limiting groove 32, the inner bucket car 20 is facilitated to move in the horizontal direction. The rotating wheel 34 can be multiple, and the multiple rotating wheels 34 are distributed along the length direction of the limiting groove 32. The rotating wheel 34 is also connected with the side wall of the inner bucket car 20, such as rotationally connected, that is, the rotating wheel 34 can rotate relative to the inner bucket car 20.

[0056] In some embodiments, as shown in Figure 5 , Figure 6 As shown, the guided member 33 includes a horizontally arranged first steel belt 35; the limiting member 31 includes two horizontally arranged second steel belts 36 which are parallel to each other and maintain a distance along the height direction of the outer bucket 10 to form the limiting groove 32; the first steel belt 35 is located between the two second steel belts 36. The first steel belt 35 is welded and fixed with the inner bucket car 20, and the second steel belt 36 is welded and fixed with the outer bucket 10. When the guided member 33 is distributed on both sides of the inner bucket car 20, there are two corresponding first steel belts 35, which are distributed on both sides of the inner bucket car 20. The limiting member 31 has two groups, each group including two second steel belts 36. The two groups of limiting members 31 are distributed on both sides of the outer bucket 10, and the two groups of limiting members 31 are distributed one by one corresponding to the two first steel belts 35, so as to realize that each two second steel belts 36 limit and guide the movement track of one first steel belt 35.

[0057] By setting the first steel belt 35 between the two second steel belts 36, the movement track of the first steel belt 35 is limited by the second steel belt 36, which not only limits and guides the movement track of the inner bucket car 20, but also, compared with the rotating wheel 34 as the guided member 33, the structural characteristics of the first steel belt 35 and the second steel belt 36 make the limiting and guiding assembly 30 have a longer service life and reduce the maintenance cost.

[0058] In some embodiments, as shown in Figure 7 As shown, the two second steel belts 36 are away from each other at one end close to the material exit and entrance 11 to form a flared portion 361. The flared portion 361 can be formed by bending one end of the two second steel belts 36 in opposite directions to form a flared portion 361. By setting the flared portion 361 at one end close to the material exit and entrance 11, the function of pre-positioning is achieved, which facilitates the first steel belt 35 to enter between the two second steel belts 36, and facilitates the inner bucket car 20 to enter the outer bucket 10, and improves the cooperation efficiency of the outer bucket 10 and the inner bucket car 20 and the material hoisting efficiency.

[0059] The two second steel belts 36 are close to each other at the end far from the material outlet 11 to form a closing part 362. The closing part 362 can be formed by bending the end of the two second steel belts 36 in opposite directions to form a tapered closing part 362. By arranging the closing part 362 at the end far from the material outlet 11, as the inner bucket car 20 enters the outer hanging bucket 10, the first steel belt 35 is inserted between the two second steel belts 36 and gradually moves to the closing part 362 until the first steel belt 35 reaches the closing part 362 and is clamped by the closing part 362, which ensures the stable connection between the inner bucket car 20 and the outer hanging bucket 10 and avoids the shaking of the inner bucket car 20 in the outer hanging bucket 10 during the hoisting process.

[0060] As shown in Figure 1 , 2 The limiting and guiding assembly 30 further includes a traction member 37 connected with the inner bucket car 20 for pulling the inner bucket car 20 into or out of the outer hanging bucket 10. By pulling the inner bucket car 20 into or out of the outer hanging bucket 10 through the traction member 37, the labor intensity is reduced. When multiple inner bucket cars 20 are arranged in the outer hanging bucket 10, the traction member 37 can guide the multiple inner bucket cars 20 to enter or leave the outer hanging bucket 10 in an orderly manner, thereby improving the cooperation efficiency of the inner bucket car 20 and the outer hanging bucket 10 and the material transfer efficiency.

[0061] In some embodiments, as shown in Figure 8 , 9 The traction member 37 includes a winch 371 and a traction rope 372, one end of the traction rope 372 is wound around the winch 371, and the other end of the traction rope 372 is connected with the inner bucket car 20 in a detachable manner. The winch 371 can be fixedly installed in the outer hanging bucket 10 or at the bottom of the outer hanging bucket 10 or outside the outer hanging bucket 10. In this embodiment, the winch 371 is preferably arranged outside the outer hanging bucket 10, and the outer hanging bucket 10 adopts a frame structure formed by welding steel pipes and having hollow holes for facilitating the arrangement of the traction rope 372. The inner bucket car 20 is driven to enter or leave the outer hanging bucket 10 by the traction force provided by the winch 371 cooperating with the traction rope 372, which is suitable for the transfer of heavy materials. The other end of the traction rope 372 is provided with a pull hook, and the front end of the inner bucket car 20 is provided with a pull ring. When the inner bucket car 20 needs to enter the outer hanging bucket 10, the pull hook of the traction rope 372 is connected with the pull ring of the front end of the inner bucket car 20, and under the action of the winch 371, the traction rope 372 pulls the inner bucket car 20 to move forward to enter the outer hanging bucket 10, as shown in Figure 8 , Figure 8 The arrow on the traction rope 372 indicates the pulling direction, and the arrow below the inner bucket car 20 indicates the moving direction of the inner bucket car 20. As shown in Figure 9As shown, the traction member 37 further comprises a traction bracket 373 and a traction steering wheel 374. The traction bracket 373 is welded to the bottom end of the outer hopper 10 or the side end of the outer hopper 10, and is located on the side close to the material inlet 11 relative to the winch 371. The traction steering wheel 374 is arranged at the top end of the traction bracket 373 and is rotatable relative to the traction bracket 373. The axle of the traction steering wheel 374 is horizontally arranged. The traction rope 372 is connected with the winch 371 after passing through the traction steering wheel 374. When the inner bucket 20 needs to move away from the outer hopper 10, the pull hook of the traction rope 372 is connected with the pull ring at the front end of the inner bucket 20. The winch 371 is operated, the traction rope 372 is wound on the winch 371, and the traction rope 372 passing through the traction steering wheel 374 drives the inner bucket 20 to move backward to move away from the outer hopper 10. In the embodiment, the rear end of the inner bucket 20 can also be provided with a pull ring. One end of the traction rope 372 is connected with the winch 371, and the other end is connected with the pull ring at the rear end of the inner bucket 20. Of course, the traction rope 372 can also pass through the traction steering wheel 374 and be wound under the action of the winch 371 to drive the inner bucket 20 to move into the outer hopper 10.

[0062] As shown in the traction member 37, Figure 1 , 2 The traction member 37 comprises a telescopic pull rod 375. One end of the telescopic pull rod 375 is provided with a handle, and the other end of the telescopic pull rod 375 is rotatably connected with the inner bucket 20. The rotatable connection mode is preferably a hinge connection, that is, the telescopic pull rod 375 is connected with the inner bucket 20 through a hinge, so that the telescopic pull rod 375 can rotate relative to the inner bucket 20. The telescopic pull rod 375 can not only drive the inner bucket 20 to enter or move away from the outer hopper 10, but also facilitate the traction of the inner bucket 20 in the material yard or the unloading platform, and is more convenient and flexible to use. Compared with the winch 371 and the traction rope 372 used in the traction member 37, the telescopic pull rod 375 used as the traction member 37 is labor-saving without the winch 371, but is relatively flexible to use, and there is no connection or separation work of the pull hook of the traction rope 372 and the pull ring of the inner bucket 20, which is suitable for the transfer of lighter materials.

[0063] In some embodiments, the traction member 37 comprises a traction motor 376 and a traction wheel. The traction motor 376 drives the traction wheel to rotate. The traction motor 376 is arranged on the side wall of the inner bucket 20, and the traction wheel is located in the limiting groove 32 and is rotatably connected with the limiting groove 32. The traction wheel is automatically rotated under the action of the traction motor 376 relative to the rotating wheel 34 rotatably connected with the limiting groove 32, and the traction wheel realizes walking in the limiting groove 32, thereby driving the inner bucket 20 to move. In order to realize the movement of the inner bucket 20, the surface of the traction wheel should be provided with anti-skid lines or anti-skid grooves.

[0064] As shown in the traction member 37, Figure 10As shown, the traction wheel comprises a traction gear 377, the traction motor 376 drives the traction gear 377 to rotate, a rack 378 engaged with the traction gear 377 is arranged in the limiting groove 32, and the rack 378 is fixed on the side wall of the outer bucket 10. Through the cooperation of the traction gear 377 and the rack 378, the movement track of the inner bucket 20 can be limited and guided, and the inner bucket 20 can be stopped at any position during movement, and the anti-skid and anti-shaking effects are good, and the safety is improved. In combination with the description of the first steel belt 35 and the second steel belt 36 in the foregoing, it can be understood that the traction gear 377 is replaced by the first steel belt 35, and one of the two second steel belts 36 matched with the first steel belt 35 is replaced by the rack 378. The traction gear 377 is engaged with the rack 378, and the rack 378 is fixed, so that the traction gear 377 rotates while moving along the length direction of the rack 378 to drive the inner bucket 20 to move. When the inner bucket 20 does not need to move in the outer bucket 10, the traction motor 376 stops driving the traction gear 377, and the traction gear 377 no longer rotates, so that the inner bucket 20 stops moving.

[0065] In some embodiments, as Figure 11As shown, the limiting guide assembly 30 further comprises a plurality of electromagnets 379 arranged along the length direction of the limiting groove 32, and the guided member 33 comprises a magnet 3710 magnetically attracted and / or repelled to the electromagnets 379. The electromagnets 379 are further electrically connected to an electric control device arranged in the outer bucket 10, and the magnetic property and magnetic force of each electromagnet 379 are controlled by the electric control device, which can be realized by using the prior art. The magnet 3710 can be arranged in the limiting groove 32, and the electromagnets 379 can be distributed in the top and bottom of the limiting groove 32 in the horizontal direction, and under the action of the electromagnets 379, the magnet 3710 is driven to move along the length direction of the limiting groove 32. In order to facilitate understanding of the movement of the magnet 3710 driven by the electromagnets 379, five electromagnets 379 arranged along the length direction of the limiting groove 32 are sequentially marked as A, B, C, D and E; assuming that the magnet 3710 is at the electromagnet 379B, if it needs to be moved to the electromagnet 379E, the electromagnet 379A provides repulsion, and the electromagnets 379C, 379D and 379E provide attraction in turn, and the attraction increases in turn, so as to realize the movement of the magnet 3710 from the electromagnet 379B to the electromagnet 379E. When the outer bucket 10 is provided with two material exits 11, one of which is used for entering the inner bucket 20, and the other is used for leaving the inner bucket 20, the two ends of the limiting groove 32 are communicated with the two material exits 11 respectively. The continuous entry and exit of the inner bucket 20 in the outer bucket 10 is realized, and the efficiency of feeding and discharging is improved, and the cooperation of the electromagnets 379 and the magnet 3710 further improves the continuity of the entry and exit of the inner bucket 20. In order to realize the continuity of the limiting groove 32, a plurality of electromagnets 379 are arranged continuously, for example, a plurality of electromagnets 379 are arranged in the horizontal direction to form a first row of electromagnet groups 3711, and another plurality of electromagnets 379 are arranged in the horizontal direction to form a second row of electromagnet groups 3712. The first row of electromagnet groups 3711 and the second row of electromagnet groups 3712 are kept apart in the vertical direction to form the limiting groove 32. The magnet 3710 is arranged between the first row of electromagnet groups 3711 and the second row of electromagnet groups 3712. The electromagnets 379 of the first row of electromagnet groups 3711 and the electromagnets 379 of the second row of electromagnet groups 3712 at the ends of the limiting groove 32 are sequentially away from each other in the direction close to the material exit 11 to form the flared portion 361.

[0066] It should be noted that the separable bucket of the present application further comprises a power supply device, such as a battery or a power supply, which provides electric energy for the winch 371, the traction motor 376, the electric control device, the electromagnets 379 and other devices.

[0067] As Figure 1 , 2The side end of the outer bucket 10 is also provided with a ramp plate 14 for closing or opening the material outlet 11; the ramp plate 14 is rotationally connected with the bottom end of the material outlet 11, for providing a ramp for the inner bucket 20 to enter or leave the outer bucket 10. The rotational connection can be realized by a hinge. The ramp plate 14 is a steel plate, the bottom end of which is hinged with the bottom end of the material outlet 11 by a hinge, and the top end of the ramp plate 14 is provided with a lock catch or a latch 15, which can be used to fix the ramp plate 14 at the side end of the outer bucket 10, so as to realize the closing of the material outlet 11, or the ramp plate 14 can be lowered to open the material outlet 11 by releasing the lock catch or pulling out the latch 15. The ramp plate 14 can not only be used to close the material outlet 11 to ensure the closure of the side end of the outer bucket 10 and improve the construction safety; but also can provide a ramp for the inner bucket 20 to enter or leave the outer bucket 10 after the material outlet 11 is opened, so as to avoid that the casters 22 of the inner bucket 20 are stuck in the gap between the unloading platform and the floor when the inner bucket 20 moves.

[0068] Based on the same inventive concept, the application further provides a material transfer method for high-rise building construction, which utilizes the separable bucket and the tower crane to transfer materials, and comprises the following steps:

[0069] Step 1: The hook of the tower crane is used to cooperate with the lifting rope 12 of the outer bucket 10 of the separable bucket to hoist the outer bucket 10 with the empty inner bucket 20 to the material yard for parking, the at least one empty inner bucket 20 in the outer bucket 10 is guided to leave the outer bucket 10 by the limiting guide assembly 30, the empty inner bucket 20 leaving the outer bucket 10 is towed to the material stacking point of the material yard, the target material of the material stacking point is filled into the loading hopper 21 of the empty inner bucket 20, and a full load inner bucket 20 is formed.

[0070] It should be noted that there are multiple inner buckets 20 at the material stacking point, and at least one full load inner bucket 20 has been formed at the material stacking point before the empty inner bucket 20 reaches the material stacking point, so as to shorten the waiting time of the outer bucket 10 at the material yard.

[0071] In the case of the traction member 37 of the position-limiting guide assembly 30 comprising a telescopic pull rod 375, the step of guiding at least one empty inner bucket car 20 in the outer bucket 10 out of the outer bucket 10 by the position-limiting guide assembly 30 comprises the following steps: releasing the fixing of the top end of the ramp plate 14 to the outer bucket 10 to open the material access opening 11, rotating the ramp plate 14 to provide a ramp for the movement of the inner bucket car 20, and a worker holding the telescopic pull rod 375 to pull the inner bucket car 20 located in the outer bucket 10 out. During the pulling process, the guided member 33 of the inner bucket car 20 moves in the position-limiting groove 32, and the position-limiting groove 32 limits the movement track of the inner bucket car 20. After the worker pulls the inner bucket car 20 out of the outer bucket 10 by the telescopic pull rod 375, the worker continues to pull the inner bucket car 20 to tow the empty inner bucket car 20 to the material depositing point.

[0072] The step of filling the target material at the material depositing point into the loading bucket 21 of the empty inner bucket car 20 to form a full-load inner bucket car 20 comprises the following steps: using a small hoist to hoist the target material into the loading bucket 21 of the inner bucket car 20; or tilting the loading bucket 21 of the inner bucket car 20 to transfer the target material at the material depositing point into the loading bucket 21 by using a manual shovel or a forklift. This process can adopt the existing method.

[0073] Step 2: guiding at least one full-load inner bucket car 20 in the material yard into the outer bucket 10 parked in the material yard in step 1 by the position-limiting guide assembly 30. The specific steps comprise the following steps: a worker moves the full-load inner bucket car 20 to the material access opening 11 of the outer bucket 10, pushes the full-load inner bucket car 20, aligns the guided member 33 with the position-limiting groove 32, and continues to push the inner bucket car 20 along the length direction of the position-limiting groove 32 of the outer bucket 10. The guided member 33 moves in the position-limiting groove 32 until the inner bucket car 20 completely enters the outer bucket 10. The ramp plate 14 is used to close the material access opening 11.

[0074] When an empty inner bucket car 20 is removed from the outer bucket 10, if there is a full-load inner bucket car 20 in the material yard, the full-load inner bucket car 20 can be pushed into the outer bucket 10 to replace the original empty inner bucket car 20. Of course, the material in the full-load inner bucket car 20 should be the target material required.

[0075] Step 3: hoisting the outer bucket 10 with the full-load inner bucket car 20 in step 2 to the unloading platform of the target floor of the high-rise building by the tower crane, guiding the full-load inner bucket car 20 out of the outer bucket 10 by the position-limiting guide assembly 30, unloading the target material in the full-load inner bucket car 20 to the unloading platform to form an empty inner bucket car 20, and guiding at least one empty inner bucket car 20 in the same target floor into the outer bucket 10. The steps of the inner bucket car 20 entering or leaving the outer bucket 10 in step 3 are similar to those in step 2.

[0076] Step 4, repeat the above steps 1-3 until all target floors of the high-rise building have the target material stacked on the discharge platform.

[0077] It should be noted that the target material of different target floors is not necessarily the same, so the method of the embodiment can be applied to the efficient transfer of different target materials.

[0078] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall be considered as falling within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
