Technical Field
[0001] This invention relates to the field of underground transportation technology, and in particular to a method for alternating transport of people and goods in an inclined shaft in an underground space. Background Technology
[0002] With socio-economic development, urban construction, water conservancy and hydropower systems, transportation systems, coal mining systems, and scientific research are increasingly developing and utilizing underground space to alleviate the objective reality of insufficient land resource supply. The development and utilization of underground space inevitably involves the transportation of personnel and goods. Currently, vertical shaft elevators / cages or inclined shaft hoists are commonly used. The former has higher investment costs and is mainly used for transporting personnel, while also accommodating small goods; the latter can transport both personnel and large goods, but suffers from poor safety for personnel transport and limitations on the volume of goods transported.
[0003] Specifically, for vertical shaft elevator / cage transportation, either elevators or cages can be used when the travel distance is less than 200m. When the travel distance is greater than 200m, ordinary elevators are insufficient, and using non-standard elevator designs would drastically increase costs. Therefore, cages are often used. However, the start and stop of cages require control by ground personnel, which is less convenient than elevators. For inclined shaft hoist rail transportation, a ground track compatible with both personnel and freight vehicles can be selected, along with ground or underground personnel and freight vehicle transfer yards, to achieve alternating transportation of personnel and goods. The disadvantage of this solution is that the track gauge is relatively small, resulting in poor safety. Alternatively, a combination of ground track (for freight transportation) and top track (for transporting personnel via gondolas or gantry cranes) can be used to achieve alternating transportation of personnel and goods. The disadvantage of this solution is that when transporting large goods, the drive heads of the overhead gondolas or gantry cranes may interfere with the goods, affecting normal transportation operations. Both of the above methods involve alternating transportation of personnel and goods. Therefore, it is necessary to frequently change the connection between the vehicle body (or crane / cable) and the power mechanism. This process is time-consuming and labor-intensive, and is prone to safety accidents such as injuries caused by steel cables.
[0004] It is evident that ensuring the safe and efficient transportation of people and goods between ground and underground spaces is a pressing issue that needs to be addressed. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides a method for alternating transport of personnel and goods in an inclined shaft in underground space, specifically employing the following technical solution:
[0006] The underground space inclined shaft alternating personnel and goods transportation method of the present invention is realized through an underground space inclined shaft alternating personnel and goods transportation system:
[0007] The underground space inclined shaft passenger and freight alternating transport system includes an inclined shaft extending from the ground to the underground. A passenger and vehicle parking lot is set up on the ground, and a freight car storage workshop is set up underground. The passenger and vehicle parking lot is equipped with a passenger and vehicle irregular track extending to the bottom of the inclined shaft. The freight car storage workshop is equipped with a freight car track extending to the ground work hall. The passenger and vehicle irregular track is located inside the freight car track. A pusher is set on the inside of the passenger and vehicle irregular track on the ground flat section. A brake car is set on the passenger and vehicle irregular track. One end of the brake car is fixedly connected to the wire rope of the winch, and the other end is connected to the passenger car or freight car through a pin engagement.
[0008] The underground space inclined shaft alternating personnel and goods transportation method includes:
[0009] When transporting personnel, follow these steps:
[0010] At least two personnel vehicles are parked in the personnel and vehicle parking lot. When transporting personnel underground, one of the personnel vehicles is first pushed from the parking lot to the surface work hall and connected to the brake vehicle with a pin. Then, a pusher pushes the personnel vehicle towards the entrance of the inclined shaft, while the winch connected to the brake vehicle simultaneously lowers the wire rope. When the personnel vehicle reaches the inclined section of the shaft, the pusher returns to its original position. Under gravity, the brake vehicle and the personnel vehicle move downwards along the inclined shaft, and the winch wire rope continues to lower. When the personnel vehicle and the brake vehicle reach the boarding point, they stop, and personnel board. The winch wire rope continues to lower, and when the personnel vehicle and the brake vehicle reach the disembarking point, they stop, and personnel disembark. When it is necessary to transport personnel to the surface, personnel board at the disembarking point, the winch wire rope is wound up, and the personnel vehicle and the brake vehicle are lifted to the boarding point and stopped, and personnel disembark. This completes one cycle of personnel transportation.
[0011] When transporting goods, follow these steps:
[0012] Remove the pin, separate the personnel car and the brake car, and push the personnel car to the personnel car parking lot for storage; use a pusher to push the brake car to the inclined shaft slope, and then reset the pusher. Under gravity, the brake car moves downwards along the inclined shaft while the winch lowers the wire rope until it reaches the underground level section. A forklift is then used to push the first truck out of the truck storage area and connect the truck and brake car with a pin. Next, the winch wire rope is wound up, lifting the truck and brake car to the surface work hall for unloading or loading. Afterwards, a pusher is used to push the truck towards the inclined shaft entrance while the winch wire rope is lowered. When the truck reaches the inclined section of the shaft, the pusher returns to its original position. Under gravity, the brake car and truck move downwards along the inclined shaft, and the winch wire rope continues to lower. When the truck and brake car reach the underground level section, the pin between them is removed, and the truck is then pushed to the unloading or loading area by a forklift for unloading or loading. While the truck is being unloaded or loaded underground, the second truck is pushed out of the truck storage area and connected to the brake car pin. The second cargo transportation cycle is then performed following these steps. After the first truck is unloaded, it can be pushed to the truck storage workshop by forklift and parked for later use.
[0013] The winch is located on the ground and outside the ground work hall.
[0014] A sheave is installed between the winch and the ground working hall, and the winch's wire rope is connected to the brake after passing through the sheave.
[0015] The boarding point is located at the upper part of the inclined shaft of the irregular track for personnel and vehicles, near the entrance, and the disembarking point is located at the bottom of the inclined section of the inclined shaft for personnel and vehicles.
[0016] The irregularly shaped track for personnel and vehicles is equipped with a sliding turnout near the parking lot for personnel and vehicles, and the track for freight cars is equipped with a switch turnout near the freight car storage workshop.
[0017] The irregularly shaped track for the vehicle is also equipped with anti-fall rollers.
[0018] The ground work hall is equipped with a material conveying bridge machine.
[0019] The underground inclined shaft personnel and goods alternating transport method provided by this invention is achieved through an ingeniously structured, easy-to-construct, and low-maintenance underground inclined shaft personnel and goods alternating transport system. It employs a parallel arrangement of irregularly shaped tracks for personnel vehicles and freight vehicles, which widens the track gauge of the freight vehicle track and improves the safety of goods transportation. Simultaneously, horizontal guide wheels are installed on the irregularly shaped tracks for personnel vehicles, enhancing the reliability of personnel transport. In operation, the personnel vehicle or freight vehicle is connected to the winch via a braked vehicle, using a pin-shaft connection instead of the traditional wire rope threading method. This significantly reduces the labor intensity of operators and increases the reliability of equipment operation during each vehicle change. In summary, this invention effectively ensures the safety of personnel and goods transportation between surface and underground spaces and significantly improves the efficiency of personnel and goods transportation between surface and underground spaces.

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific working processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.
[0025] like Figure 1-4As shown, the underground inclined shaft personnel and goods alternating transport method of the present invention is implemented through an underground inclined shaft personnel and goods alternating transport system. This system includes an inclined shaft 1 extending underground from the ground, a personnel and vehicle parking lot on the ground, and a freight car storage workshop underground. The personnel and vehicle parking lot has a personnel and vehicle irregularly shaped track 2 extending to the bottom of the inclined shaft 1. The freight car storage workshop has a freight car track 4 extending to the ground-level work hall 3, with the personnel and vehicle irregularly shaped track 2 located inside the freight car track 4. A pusher is installed inside the personnel and vehicle irregularly shaped track 2, and a brake 5 is installed on the track 2. One end of the brake 5 is fixedly connected to the wire rope 7 of a winch 6, and the other end is connected to a personnel or freight car M via a pin 8. The winch 6 is located on the ground outside the ground-level work hall 3, and a sheave 9 is installed between the winch 6 and the work hall 3, so that the wire rope 7 of the winch 6 connects to the brake 5 after passing through the sheave 9. Furthermore, anti-fall rollers 10 are installed inside the irregularly shaped personnel and vehicle track 2. The aforementioned sheave 9 ensures that the wire rope 7 is evenly wound on the winch drum 6, and the anti-fall rollers 10 prevent the wire rope 7 of the winch 6 from rubbing against the ground when the vehicle is running on the slope. The aforementioned winch 6 is also equipped with load sensors and stroke detection devices for automated remote management. To facilitate material transportation, a material transport bridge crane 11 is installed in the ground work hall 3 to assist in loading and unloading of freight cars. Normally, the personnel and vehicle parking lot is located on the left side of the ground track (facing the entrance). The irregularly shaped personnel and vehicle track 2 extends from the ground parking lot to the horizontal section of the underground inclined shaft 1. A boarding point is set at the upper part of the inclined shaft 1 near the entrance, and a disembarking point is set at the bottom of the inclined section of the inclined shaft 1, so that personnel can go up and down on the inclined section of the inclined shaft 1. The freight car track 4 extends from the ground work hall 3 through the entrance of the inclined shaft 1, the inclined shaft section, the underground horizontal section, the underground parking lot, etc., to the underground hall. To facilitate vehicle transfer, the passenger and vehicle irregular track 2 is equipped with a sliding turnout 12 near the passenger and vehicle parking lot, and the freight car track 4 is equipped with a switch turnout 13 near the freight car storage workshop.
[0026] The aforementioned irregular-shaped track 2 for personnel transport is mainly used for transporting people. The track gauge can be selected from 900mm or 600mm according to actual needs. The safety devices for the personnel vehicle include a manual brake, horizontal guide wheels, and an overspeed switch brake. In case of an accident, manual or automatic braking can be used.
[0027] Freight car track 4 is mainly used for transporting goods. Its gauge is greater than or equal to 1435mm. When the size of the transported goods is small, the smaller value is used, and when the size of the transported goods is large, the larger value is used. When the width of the goods reaches 4000mm, the gauge of freight car track 4 is generally not less than 1800mm.
[0028] The brake car 5 is located upstream of the personnel car or freight car, shares the same track with the personnel car, and is always connected to the wire rope 7 of the winch 6. When transporting personnel, the personnel car is connected to the brake car 5; when transporting goods, the freight car is connected to the brake car 5.
[0029] The method for alternating transport of people and goods in an inclined shaft in underground space according to the present invention includes:
[0030] When transporting personnel, follow these steps:
[0031] At least two personnel vehicles M are parked in the personnel and vehicle parking lot. When transporting personnel underground, one of the personnel vehicles M is first pushed from the personnel and vehicle parking lot to the ground work hall 3 and connected to the brake vehicle 5 with a pin 8. Then, the pusher pushes the personnel vehicle M towards the entrance of the inclined shaft 1, while the winch 6 connected to the brake vehicle 5 releases the steel cable 7 simultaneously. When the personnel vehicle M reaches the inclined section of the inclined shaft 1, the pusher returns to its original position, and the winch 6 continues to release the steel cable 7. When the personnel vehicle M and the brake vehicle 5 reach the boarding point, they stop, and the personnel board. The winch 6 continues to release the steel cable 7, and when the personnel vehicle M and the brake vehicle 5 reach the disembarkation point, they stop, and the personnel disembark. When it is necessary to transport personnel to the ground, the personnel board at the disembarkation point, the winch 6 rewinds the steel cable 7, and lifts the personnel vehicle M and the brake vehicle 5 to the boarding point, where they stop, and the personnel disembark. This completes one cycle of personnel transportation.
[0032] When transporting goods, follow these steps:
[0033] Remove the pin, separate the personnel carrier M and the brake car 5, and push the personnel carrier M to the personnel carrier parking lot for storage; then, lower the winch 6 wire rope 7 to move the brake car 5 to the underground level section, use a forklift to push a truck M out of the truck storage workshop, and connect the truck M and the brake car 5 together with the pin 8; then, windlass 6 wire rope 7 is wound up to lift the truck M and the brake car 5 to the ground working hall 3 for unloading or loading; after that, push the truck M towards the entrance of the inclined shaft 1 using a pusher, while lowering winch 6. When the freight car M reaches the inclined section of the shaft, the pusher returns to its original position. The winch 6 continues to lower the wire rope 7. When the freight car M and the brake car 5 reach the underground level section, the pin 8 between the freight car M and the brake car 5 is removed. Then, a forklift pushes the freight car to the unloading or loading area for unloading or loading. While the freight car M is unloading or loading underground, the second freight car M is pushed out of the freight car storage workshop and connected to the pin of the brake car 5. The second cargo transportation cycle is then carried out following the above steps. After the first freight car is unloaded, it can be pushed to the freight car storage workshop by a forklift for later use.
