Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, specifically to a miniature starting well rapid material transport device. Background Technology

[0002] In the current construction of small-scale shield tunnels in cities, the application of small launching shafts is becoming increasingly widespread to adapt to narrow construction sites. However, the contradiction between the confined space of these shafts and the traditional method of transporting materials using truck cranes is becoming increasingly prominent: the intermittent operation mode of truck cranes leads to low vertical transportation efficiency, becoming a key bottleneck restricting the speed of shield tunneling; the operation process involves blind spots in command and control, and personnel needing to hook onto heavy loads, which brings significant safety risks; at the same time, the large cranes' requirements for site bearing capacity and space are difficult to meet in urban construction.

[0003] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a miniature starting well rapid material transport device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A miniature launching shaft rapid material transport device includes a track-moving platform installed in the underground working area; a moving track installed on top of the track-moving platform; a chain-guided freight elevator vertically installed inside the launching shaft for lifting and transporting materials between the ground and underground; a fixed track installed on the base plate of the chain-guided freight elevator, with one end of the fixed track connected to one end of the moving track; a U-shaped track laid on the ground, with one end of the U-shaped track connected to the other end of the fixed track; a segment trolley running on the U-shaped track, fixed track, and moving track for carrying segments or construction materials; a loading area located on one side of the U-shaped track for loading the segment trolley; and a battery-powered locomotive located on one side of the track-moving platform for towing the segment trolley in and out of the shield tunnel.

[0007] Furthermore, to ensure a stable connection between the ground track, the freight elevator track, and the underground moving track, and to construct a continuous closed-loop transportation channel, the moving track and the fixed track are on the same horizontal plane after the chain-guided freight elevator descends to its position, and are connected by detachable connecting rails. The connection points of the connecting rails are fastened to the moving track and the fixed track respectively by setting rail joint plates, high-strength rail joint bolts, and high-strength rail joint nuts, forming a continuous passage track. The U-shaped track, the fixed track inside the freight elevator, and the moving track together constitute a closed-loop track line for the continuous cyclical travel of the segment car.

[0008] Furthermore, in order to enable rapid assembly, disassembly, and operation between segment cars and between segment cars and battery locomotives, and to ensure the long-term stable operation of the ground track, adjacent segment cars are detachably connected by pins and connecting plates; the U-shaped track includes two parallel steel rails, which are reinforced by welding transverse steel bars and fixed to pre-embedded steel plates on the ground by clamps on both sides of the rails; the battery locomotive and segment cars are detachably connected by pins and connecting plates.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. Through the coordinated action of the track-moving platform, moving track, chain-guided freight elevator, fixed track, U-shaped track, segment car, loading area and battery locomotive, a fully closed-loop continuous device is constructed, which integrates ground loading, vertical transportation, underground transfer and tunnel transportation. This replaces the traditional intermittent truck crane material transportation mode and realizes seamless connection and circulation of materials such as segments between different processes, thereby improving the overall material supply efficiency and tunneling speed of shield tunneling.

[0011] 2. By connecting the moving track and the fixed track at the same level, and by setting up detachable connecting rails, rail joint clamps, and matching high-strength rail joint bolts and nuts, the ground track, the freight elevator track and the underground track form a continuous passage track. Furthermore, the U-shaped track, the fixed track inside the freight elevator and the moving track together form a closed-loop operation line, enabling the segment car to travel continuously in a loop, reducing manual handling and improving the continuity and stability of transportation.

[0012] 3. The adjacent segment cars and battery locomotives are connected by pins and connecting plates to achieve quick and detachable connection, which makes it convenient to flexibly adjust the number of trains and adapt to the transportation needs under different working conditions; the U-shaped track uses two parallel steel rails and is reinforced by transversely welded steel bars. It is fixed to the ground-embedded steel plate by clamps, making the ground track structure more stable and reliable, and meeting the needs of long-term and multiple heavy-load operation conditions.

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a rapid material conveying device for a miniature launching well is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-9 As shown, the miniature launching shaft rapid material transport device according to an embodiment of this utility model includes a track-moving platform 1, which is set in the underground working area; a moving track 2, which is set on the top of the track-moving platform 1; a chain-type guide rail freight elevator 3, which is vertically set in the launching shaft and used to lift and transport materials between the ground and the underground; a fixed track 4, which is set on the bottom plate of the chain-type guide rail freight elevator 3, and one end of the fixed track 4 is connected to one end of the moving track 2; a U-shaped track 5, which is laid on the ground, and one end of the U-shaped track 5 is connected to the other end of the fixed track 4; a segment trolley 6, which is set on the U-shaped track 5, the fixed track 4 and the moving track 2 and is used to carry segments or construction materials; a loading area 7, which is set on one side of the U-shaped track 5 and is used to load materials onto the segment trolley 6; and a battery-powered locomotive 8, which is set on one side of the track-moving platform 1 and is used to pull the segment trolley 6 in and out of the shield tunnel.

[0028] By utilizing the above-mentioned technical solutions, a fully closed-loop continuous device is constructed through the coordinated action of the track-moving platform 1, the moving track 2, the chain-type guide rail freight elevator 3, the fixed track 4, the U-shaped track 5, the segment car 6, the material loading area 7, and the battery locomotive 8. This device replaces the traditional intermittent truck crane material transportation mode, realizes the seamless connection and circulation of materials such as segments between different processes, and thus improves the overall material supply efficiency and tunneling speed of shield tunneling.

[0029] It should be noted that the track moving platform 1 is used to drive the moving track 2 on its top to adjust its horizontal translation position. The track moving platform 1 can adopt conventional moving devices such as hydraulic drive, electric push rod or gear rack mechanism, which are existing technologies and will not be elaborated on here.

[0030] In one embodiment, for the aforementioned moving track 2, fixed track 4, and U-shaped track 5, the moving track 2 and fixed track 4 are on the same horizontal plane after the chain-guided freight elevator 3 descends to its position, and are connected by a detachable connecting rail 9. The connection point of the connecting rail 9 is fastened to the moving track 2 and fixed track 4 respectively by setting a rail joint clamp 10, a high-strength rail joint bolt 11, and a high-strength rail joint nut 12, forming a continuous passage track. The U-shaped track 5, the fixed track 4 inside the freight elevator, and the moving track 2 together constitute a closed-loop track line for the continuous cyclical travel of the segment car 6, thereby ensuring a stable connection between the ground track, the freight elevator track, and the underground moving track, and constructing a continuous closed-loop transportation channel.

[0031] In one embodiment, for the aforementioned segment car 6 and battery locomotive 8, two adjacent segment cars 6 are detachably connected to a connecting plate 14 via a pin 13; such as Figure 6 As shown, the U-shaped track 5 includes two parallel steel rails 19, which are reinforced by welding with transversely arranged reinforcing bars 15, and fixed to a pre-embedded steel plate in the ground by clamps 16 set on both sides of the steel rails 19; as Figures 7-9 As shown, the battery locomotive 8 and the segment car 6 are detachably connected by a pin 13 and a connecting plate 14, thereby enabling rapid assembly, disassembly and operation of the segment car 6 and the battery locomotive 8, and ensuring the long-term stable operation of the ground track.

[0032] The working principle of the circulating material transport is as follows: At the start of construction, three fully loaded segment cars 6 are loaded in the ground material loading area 7 and pushed by external power along the U-shaped track 5 into the compartment of the chain-guided freight elevator 3, and parked on the fixed track 4 inside the freight elevator. The chain-guided freight elevator 3 carries the segment cars 6 down to the bottom of the shaft. After the freight elevator is in place, the operators use connecting rails 9, rail joint clamps 10, high-strength rail joint bolts 11 and high-strength rail joint nuts 12 to firmly connect the fixed track 4 inside the freight elevator with the moving track 2 on the rail moving platform 1. At this time, the battery locomotive 8 in the shaft is quickly connected to the three segment cars 6 through pins 13 and connecting plates 14 to form the first train group. Then the battery locomotive 8 pulls the train group along the moving track 2 into the shield tunnel for material transport.

[0033] While the first train set enters the tunnel for operation, three empty segment cars 6 are pre-positioned on the U-shaped track 5 on the ground. One of them is pushed to the loading area 7 for loading. After being fully loaded, it runs along the U-shaped track 5 and joins the waiting queue for cyclical replacement. After the three segment cars 6 have completed loading in sequence, they enter the chain-type guide rail freight elevator 3 again, descend to the bottom of the shaft, and connect on the moving track 2 to form the second train set, waiting to enter the tunnel. When the first train set completes the transportation inside the tunnel and returns to the moving track 2 at the bottom of the shaft, the battery-powered locomotive 8 separates from the segment car 6 it is pulling. Then, the track moving platform 1 starts, driving the moving track on it. 2. Move laterally until the fully loaded second train set, which is already parked on it, is accurately moved to the tunnel entrance and connected to the battery locomotive 8. After the connection is completed, the battery locomotive 8 immediately pulls the second train set into the tunnel to realize the relay cycle of transportation operation. At the same time, the empty first train set is moved to the bottom exit position of the chain-type guide rail freight elevator 3 due to the translation of the track moving platform 1. After the operator disassembles the connecting rail 9 and other connecting parts, the empty first train set segment car 6 is pushed into the chain-type guide rail freight elevator 3 and lifted to the ground. After the segment car 6 exits the elevator, it is transported to the loading area 7 along the U-shaped track 5 to start a new round of loading operation.

[0034] It should be noted that, due to the unavoidable gap between the U-shaped track 5, the fixed track 4 inside the freight elevator, and the moving track 2 after installation, it is necessary to tighten both ends through the connecting rail 9 and the matching rail joint clamp 10, high-strength rail joint bolt 11, and high-strength rail joint nut 12, so that the three sections of track form a rigid continuous track in the working state, ensuring the smooth passage of the segment car 6; the connection between the segment car 6 and the battery locomotive 8, as well as between adjacent segment cars 6, is achieved through the pin shaft 13 and the connecting plate 14. Its structure is simplified and quick to assemble and disassemble, enabling the train set to be quickly assembled or disassembled, meeting the continuous requirements of cyclic transportation.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In practical application, construction workers first load three segment cars 6 with materials in the ground material loading area 7. Using manual pushing, winches, or other external power devices, the segment cars 6 are pushed along the U-shaped track 5 into the compartment of the chain-guided freight elevator 3 and parked on the fixed track 4 inside the elevator. The chain-guided freight elevator 3 carries the segment cars 6 down to the bottom of the shaft. After they are lowered into place, the operators connect the fixed track 4 inside the elevator with the moving track 2 on the track moving platform 1 through the detachable connecting rail 9 and the matching rail joint clamps 10, high-strength rail joint bolts 11, and high-strength rail joint nuts 12, so that the three track sections form a continuous rigid passage. The battery locomotive 8 underground is quickly connected to the three segment cars 6 through the pin shaft 13 and the connecting plate 14 to form the first train group. The battery locomotive 8 pulls the train along the moving track 2 into the shield tunnel for material transportation.

[0037] While the first train set enters the tunnel for operation, three empty segment cars 6, already parked on the U-shaped track 5 on the ground, are pushed to the loading area 7 for loading. After the three segment cars 6 are loaded in sequence, they enter the chain-type guide rail freight elevator 3 and descend to the bottom of the shaft. They connect on the moving track 2 to form the second train set, ready to enter the tunnel. At this time, the first train set completes the tunnel transport and returns to the moving track 2 at the bottom of the shaft. The battery locomotive 8 separates from the segment cars 6 it pulls. Then, the track moving platform 1 starts and moves the moving track 2 laterally to the position of the second train set, so that the second train set can immediately enter the tunnel after docking with the battery locomotive 8, realizing the relay cycle of transportation operation. At the same time, the empty first train set is moved to the bottom exit position of the chain-type guide rail freight elevator 3 due to the lateral movement of the track moving platform 1. The operators push the first train segment cars 6 into the chain-type guide rail freight elevator 3 and lift them to the ground. The segment cars 6 return to the loading area 7 along the U-shaped track 5 to start a new round of loading operation.

[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, a fully closed-loop continuous device is constructed through the coordinated action of the track-moving platform 1, the moving track 2, the chain-type guide rail freight elevator 3, the fixed track 4, the U-shaped track 5, the segment car 6, the loading area 7, and the battery locomotive 8. This device replaces the traditional intermittent truck crane material transportation mode, realizes the seamless connection and circulation of materials such as segments between different processes, and thus improves the overall material supply efficiency and tunneling speed of shield tunneling.

[0039] By connecting the moving track 2 and the fixed track 4 at the same level, and by setting up detachable connecting rails 9, rail joint clamps 10, and matching high-strength rail joint bolts 11 and high-strength rail joint nuts 12, the ground track, the freight elevator track, and the underground track form a continuous passage track. The U-shaped track 5, the fixed track 4 inside the freight elevator, and the moving track 2 together form a closed-loop operation line, allowing the segment cars 6 to run continuously in a loop, reducing manual handling and improving transportation continuity and stability. The adjacent segment cars 6 and the battery locomotive 8 are quickly and detachably connected by pins 13 and connecting plates 14, which facilitates flexible adjustment of the number of trains and adapts to transportation needs under different working conditions. The U-shaped track 5 uses two parallel steel rails 19 and is reinforced by transversely welded steel bars 15. It is fixed to the ground-embedded steel plate by clamps 16, making the ground track structure more stable and reliable, meeting the needs of long-term and repeated heavy-load operation.
