Detailed implementation manners

[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0058] Embodiment 1: A specific implementation manner for solving the problem that the existing hoist well transport vehicle can only move the transport vehicle below the goods when the goods are suspended above the hoist well corresponding to the floor

[0059] A hoist well receiving platform for receiving the goods 6 hoisted on the hoist well 41 includes a receiving platform 4. An opening for the hoist well 41 is provided on the receiving platform 4. A hoisting device 1 is arranged above the receiving platform 4. A transport vehicle 2 is arranged on the hoist well 41. A flap 22 is rotatably connected to the transport vehicle 2. A horizontal limiting plate 23 is arranged on the transport vehicle 2, and the horizontal limiting plate 23 can limit the downward rotation of the flap 22;

[0060] A through hole 221 is provided on the flap 22, and the sling and hook 15 of the hoisting device 1 can pass through the through hole 221;

[0061] When the goods 6 move upward from below the flap 22, the flap 22 will be pushed open;

[0062] After the goods 6 completely pass through the flap 22, the rotating end of the flap 22 can return to the horizontal state and be restricted by the horizontal limiting plate 23.

[0063] Among them:

[0064] A pair of flaps 22 are provided. The flaps 22 are opened from the middle to both sides. The through hole 221 is arranged between the two flaps 22. Openings are arranged at corresponding positions on the two flaps 22. When the two flaps are in the horizontal state, the openings are aligned to form the through hole 221.

[0065] The transport vehicle 2 includes a vehicle frame 21, and one end of the flap 22 is hinged to the vehicle frame 21.

[0066] Wheel axle sleeves 211 are arranged at the bottoms of both ends of the vehicle frame 21, and flap hinge parts 212 are arranged at the tops. Anti-collision beams 25 are also arranged at both ends of the vehicle frame 21.

[0067] If the transport vehicle 2 can be a rail vehicle or other transport vehicles, if a rail vehicle is adopted, then limiting plates 31 corresponding to the anti-collision beams 25 are arranged at both ends of the rail 3.

[0068] The power mechanism and the braking mechanism of the transport vehicle 2 are both prior arts. Specific issues regarding power and braking are not the technical problems to be solved by the present invention. Those skilled in the art can select the corresponding power mechanism according to actual needs without any creative work, so it will not be elaborated herein.

[0069] The lifting device 1 may include a lifting motor 11, a braking device 12, a speed reducer 13, a winch 14, and a hook 15. The output shaft of the lifting motor 11 is connected to the input shaft of the speed reducer 13. The output shaft of the speed reducer 13 is connected to the winch 14. The braking device 12 is disposed on the output shaft of the lifting motor 11 for braking the lifting motor 11. A rope is wound around the winch 14, and the lower end of the rope is connected to the hook 15.

[0070] The above-mentioned lifting device 1 is only one kind of lifting device adopted in the embodiment of the present invention, and other lifting structures should also be within the protection scope of the present invention.

[0071] During use:

[0072] S1A: Park the transport vehicle 2 below the lifting device 1;

[0073] S2A: Start the lifting device 1 and move the hook 15 of the lifting device 1 downward after passing through the through hole 221;

[0074] S3A: Install the goods 6 on the hook 15;

[0075] S4A: Start the lifting device 1 to make the hook 15 drive the goods 6 to move towards the floor where the transport vehicle 2 is located;

[0076] S5A: When the goods 6 are brought to the floor where the transport vehicle 2 is located, a pair of flappers 22 provided on the transport vehicle 2 will be pushed open;

[0077] S6A: After the goods 6 push open the flappers 22, continue to move upward until the goods 6 completely pass through the flappers 22. Subsequently, the flappers 22 return to the horizontal position under the action of their own gravity and are restricted from rotating downward by the horizontal limiting plate 23;

[0078] S7A: Start the lifting device 1 to make the hook 15 drive the goods 6 to move downward onto the flappers 22 and then unload the goods 6 from the hook 15;

[0079] S8A: Operate the transport vehicle 2 to carry the goods 6 to the designated location.

[0080] Embodiment 2: Specific implementation method for solving the problem that the existing hoistway transport vehicle cannot move the transport vehicle to the hoistway during the lifting of goods

[0081] The difference from Embodiment 1 is that: an opening A213 is provided at one end of the vehicle frame 21, the flap 22 includes an upper flap and a lower flap, an opening B222 is provided between the upper flap and the lower flap, and the opening A213 communicates with the opening B222;

[0082] The sling and hook 15 of the lifting device 1 can enter the opening B222 from the opening A213.

[0083] During use:

[0084] S1B: Start the lifting device 1 to drive the hook 15 to drive the goods 6 to move towards the floor where the transport vehicle 2 is located;

[0085] S2B: Before the goods 6 reach the floor where the transport vehicle 2 is located, operate the transport vehicle 2 to move towards the rope of the lifting device 1 so that the rope passes through the opening A213;

[0086] S3B: When the goods 6 reach the floor where the transport vehicle 2 is located, the goods 6 will push open the upper flap, lower flap and right flap provided on the transport vehicle 2, and then continue to move upward. When the goods 6 completely pass through the upper flap and the lower flap, the upper flap, lower flap and right flap return to the horizontal and are restricted from rotating downward by the horizontal limiting plate 23;

[0087] S4B: Start the lifting device 1 to drive the hook 15 to drive the goods 6 to move downward onto the upper flap, lower flap and right flap and then unload the goods 6 from the hook 15;

[0088] S5B: Operate the transport vehicle 2 to carry the goods 6 to the designated location.

[0089] When comparing Embodiment 2 with Embodiment 1, in Embodiment 1, it is necessary to let the sling and the hook 15 pass through the through hole 221 on the flap 22 in advance, while in Embodiment 2, the transport vehicle 2 can be moved to the wellhead of the lifting shaft 4 when the sling and the hook 15 are in the lifting state. Therefore, Embodiment 2 has better operation flexibility. In the traditional technology, it is necessary to wait for the goods 6 to be lifted above the wellhead before moving the transport vehicle 2 below the goods 6 to wait for transportation.

[0090] Embodiment 3: The specific implementation method for solving the problem that the support strength of the transport vehicle with an open end design is reduced

[0091] In Embodiment 2, since there are more openings provided on the vehicle frame 21 and the flap, the overall strength of the transport vehicle 2 is reduced. Embodiment 3 is made to make up for the technical problems that appear in Embodiment 2 without affecting the functions proposed in Embodiment 2.

[0092] On the basis of Embodiment 2, a telescopic rod 214 and a sleeve 215 are provided below the frame 21 at the opening A213. When the telescopic rod 214 extends, one end of the telescopic rod 214 can be inserted into the sleeve 215; when the telescopic rod 214 contracts, the sling and hook 15 of the lifting device 1 can pass through the opening A213.

[0093] In use, it is only necessary to ensure that the telescopic rod 214 is in a contracted state before the sling and hook 15 pass through the opening A213. When the transport vehicle 2 is in the transport state, the extended section of the telescopic rod 214 should be inserted into the sleeve 215 as much as possible.

[0094] It should be noted that in the description of the invention, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. is the description of the structure of the present invention based on the drawings shown. It is only for the convenience of describing the present invention simply, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present invention.

[0095] For the "first" and "second" in this technical solution, they are only the appellation distinctions for the same or similar structures, or the corresponding structures with similar functions, not the arrangement of the importance of these structures, nor are there any sorting, or comparing sizes, or other meanings.

[0096] In addition, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two structures. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the general idea of the present invention and in connection with the specific context of this solution.
