[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] The following is combined Figures 1-6 The ultra-deep vertical shaft conversion gangue metering and loading device of the present invention includes a horizontal tunnel 1, a gate 2, a metering and unloading unit 3, a bidirectional material guiding unit 4, and a double-bucket loading unit 5.

[0022] Among them, the horizontal tunnel 1 is located at the upstream of the system as a gangue transportation channel, which can collect the excavated gangue and meet the needs of transfer in the narrow tunnel of the deep shaft; the gate 2 is connected to the horizontal tunnel 1 as an underground transfer hub, where all loading equipment is centrally located to reduce the distance of gangue transfer; the metering and unloading unit 3 is located in the gate 2 and consists of a metering hopper 31 and a drive cylinder 32. The drive cylinder 32 drives the metering hopper 31 to flip and unload, replacing manual gangue removal and eliminating the manual gangue moving process; the bidirectional feeding unit 4 is located at the bottom of the metering and unloading unit 3, and the feed port receives the dumped gangue, collecting the gangue completely without spillage. The dual-bucket loading unit 5 includes a main bucket 51 and an auxiliary bucket 52. The main bucket 51 and the auxiliary bucket 52 are respectively located below the two discharge ports of the bidirectional material guiding unit 4. The internal deflector baffle 43 can switch the flow direction of gangue, realize the alternating continuous loading of the two buckets, eliminate the gap in bucket operation, and improve the continuity of slag discharge.

[0023] In the above embodiments, the integrated transfer and loading system integrates the entire process of conveying, transferring, metering and loading. It can adapt to various deep shaft tunnel excavation conditions without modifying the original vertical shaft facilities. The overall structure is compact and solves the problems of slow slag loading and scattered processes in traditional fixed chute systems.

[0024] See Figure 4 As shown, in a specific embodiment of the present invention, the metering and unloading unit 3 further includes a first foundation pit 33 and a base 34; the first foundation pit 33 is excavated on the ground of the horse-head gate 2, and a concrete foundation is poured at the bottom, which can isolate blasting vibration, improve the load-bearing rigidity of the equipment, and prevent the base plate from being deformed by pressure; the base 34 is fixed inside the first foundation pit 33, and the metering hopper 31 is rotatably assembled on the base 34. The two ends of the driving cylinder 32 are respectively hinged to the back of the base 34 and the back of the metering hopper 31. The inclined cylinder drives the metering hopper 31 to flip and unload by thrust. The torque is sufficient and there is no gangue residue after unloading. The base 34 disperses the full load of gangue, reduces the wear of the metering hopper 31, and extends the service life of the equipment.

[0025] In the above embodiments, the separate support structure of the first pit 33 and the base 34 provides an independent and stable installation space for the metering bucket 31, making underground assembly convenient and preventing equipment displacement or overturning problems during long-term operation.

[0026] See Figure 5 As shown, in a specific embodiment of the present invention, a slide rail 35 is added. The slide rail 35 is fixed to the bottom of the metering hopper 31 and forms a sliding fit with the base 34. The slide rail 35 can slide slightly to adjust the front and rear position of the metering hopper 31, accurately aligning it with the feed inlet of the chute below, so that the unloading is free from deviation and spillage. At the same time, the slide rail 35 disperses the vertical pressure, reduces the friction loss between the metering hopper 31 and the base 34, reduces the frequency of equipment maintenance, and the sliding adjustment adapts to the size deviation of the underground installation without the need for on-site cutting and modification of the equipment.

[0027] In the above embodiments, the sliding pair of slide rail 35 has the dual functions of position fine adjustment and wear-resistant protection, reducing the difficulty of on-site assembly and debugging, and adapting to the narrow and restricted construction space underground.

[0028] See you again Figure 4 As shown, in a specific embodiment of the present invention, the metering and unloading unit 3 further includes a closed anti-spillage structure, which includes a second foundation pit 36, a supporting hydraulic arm 38, and a closed platform 37. The second foundation pit 36 ​​is located inside the first foundation pit 33 and independently houses the supporting hydraulic arm 38, without occupying the working space of the metering hopper 31, resulting in a compact overall layout. The bottom end of the supporting hydraulic arm 38 is fixed to the second foundation pit 36, and the top end is connected to the closed platform 37, which can raise the closed platform 37 to the same height as the metering hopper 31, sealing the gap between the metering hopper 31 and the rock wall, preventing the spillage of gangue during the collection and unloading process, and eliminating the need for manual cleaning of spilled gangue. The hydraulic arm 38 can lock the height of the closed platform 37, so that the closed platform 37 will not sink or shift under blasting vibration, maintaining the anti-spillage effect for a long time.

[0029] In the above embodiments, the enclosed anti-spraying structure solves the problem of waste accumulation in traditional chute spillage, reduces additional cleaning procedures downhole, and improves the cleanliness of the working environment and construction efficiency.

[0030] In a specific embodiment of the present invention, the main body of the bidirectional material guiding unit 4 is a bidirectional streamlined chute 41 with a Y-shaped streamlined inner wall that is smooth and without dead corners. The gangue slides down at a uniform speed by its own weight, eliminating the blockage and material stagnation faults of traditional chutes and ensuring continuous slag loading. The steering shaft 42 is fixed to the chute inlet frame, and the steering baffle 43 is sleeved on the steering shaft 42 and can swing left and right. The simple hinge structure has low swing resistance, and the electronic control switching of the flow direction is quick, eliminating the need for the bucket to wait for a long time to change positions. The one-piece molded chute is wear-resistant and erosion-resistant, and is not easy to crack or deform in the humid and dusty underground environment.

[0031] In the above embodiments, the streamlined bifurcation chute is equipped with a swingable steering baffle 43 to achieve bidirectional and precise diversion of gangue, continuously supplying material to the main bucket 51 and the auxiliary bucket 52 in a timed manner, and maximizing the recycling rate of the buckets.

[0032] In a specific embodiment of the present invention, an electronic control system is also included. The electronic control system drives the hydraulic cylinder 32 and the steering baffle 43 in conjunction with each other. It can simultaneously issue commands for the extension and retraction of the hydraulic cylinder and the rotation of the baffle. It integrates integrated control logic, and the entire slag loading process only requires one person to operate, eliminating the traditional multi-person collaborative alignment, gangue removal, and bucket stabilization processes. The electronic control system precisely controls the stroke of the hydraulic cylinder and the swing angle of the baffle, and the unloading amount and material flow direction are controllable, avoiding overloading of gangue and spillage of gangue. The centralized electronic control system simplifies the underground operation process, reduces the cross-operation of multiple trades, and reduces the safety hazards of falling gangue and collision injuries.

[0033] In the above embodiments, the integrated electronic control linkage structure realizes full automation of the slag loading process, reduces the labor intensity of workers, and improves the inherent safety of the slag discharge process.

[0034] In a specific embodiment of the present invention, the entire equipment frame is anchored to the deep rock of the tunnel by multiple reinforcing anchor bolts. The deep anchoring of the anchor bolts enhances the equipment's resistance to overturning and impact, and resists the continuous vibration of tunneling and blasting. Concrete is poured on the outside of the equipment and the sidewalls of the foundation pit, and concrete partition walls are built to form a composite reinforcement structure of anchor bolts and concrete. The equipment is integrated with the tunnel rock mass and will not shift during long-term operation. The concrete partition walls isolate underground water and dust, protect precision components such as oil cylinders, shafts, and electrical controls, reduce the corrosion failure rate, and reduce the amount of underground maintenance work.

[0035] In the above embodiments, the composite reinforcement structure is suitable for complex stress and humid and dusty working conditions in deep wells. The equipment has strong stability, low operation and maintenance costs, and can be continuously put into tunneling and slag removal operations for a long time.

[0036] This invention also provides a construction method for an ultra-deep vertical shaft conversion gangue metering and loading device, comprising: S1. Gangue is transported along the horizontal tunnel 1 to the metering hopper 31. It relies on fixed volume to quantitatively collect materials. The fixed volume realizes accurate metering of gangue, and the closed platform 37 at the same time prevents gangue from spilling. S2. The electrically controlled hydraulic cylinder 32 extends to drive the metering hopper 31 to tilt and unload the material. After unloading is completed, the hydraulic cylinder automatically resets, and the hydraulic automatic unloading eliminates the need for manual slag removal. S3, the electric control steering baffle 43 switches the discharge direction, guiding the material to the main bucket 51 and the auxiliary bucket 52, ensuring smooth material flow without blockage; S4. After the bucket is full, it is lifted and transported out. The metering hopper 31 collects material synchronously in a circulating manner. The two buckets work alternately without any gaps, and the slag is continuously discharged without interruption. S5. When the operation is completed, shut down the hydraulic system and lock the oil cylinder. The metering hopper 31 is laid flat and the baffle is returned to its position for standby. No re-alignment or adjustment is required when restarting.

[0037] In the above embodiments, the collection, unloading and transfer are carried out in a closed loop in parallel. The hoisting of the bucket and the collection of the metering bucket 31 are carried out simultaneously, eliminating the invalid waiting time of the bucket underground and shortening the tunneling construction cycle.

[0038] In a specific embodiment of the present invention, a pre-assembly process is added before step S1. First, the foundation pits of the metering hopper 31, hydraulic arm, and bidirectional chute 41 are excavated and concrete foundations are poured. The unified benchmark is used for leveling, and the equipment assembly and alignment accuracy is high, and the equipment is qualified in one go.

[0039] The above-ground prefabricated metering and unloading unit, bidirectional material guiding unit, and double-bucket loading unit are assembled underground using only bolts, avoiding on-site welding, formwork, and maintenance, and shortening the underground installation period. The equipment frame is anchored by driving in anchor bolts, and concrete is poured and concrete partition walls are built to complete the composite reinforcement. The installation and reinforcement are completed in one go, reducing the time occupied in the roadway and not delaying the tunneling progress.

[0040] In the above embodiments, the modular prefabrication and assembly construction mode is suitable for narrow single-ended roadways, simplifies on-site construction procedures, and reduces the difficulty and cost of underground construction.

[0041] In a specific embodiment of the present invention, the unloading of the metering hopper 31 and the loading of the bucket are controlled within 1 minute, which significantly reduces the waiting time for the bucket underground compared to traditional processes, resulting in a leapfrog improvement in gangue removal efficiency. The complete cycle of lifting, lowering, and resetting the bucket takes a stable 6-9 minutes, matching the tunneling and muck removal rhythms and preventing gangue accumulation and blockage at the working face. Only one operator is required for electrical control throughout the entire process, reducing manpower input compared to traditional multi-person operations, lowering labor costs, and eliminating the safety hazards of multiple personnel working simultaneously.

[0042] In the above embodiments, mechanization is achieved to reduce manpower and increase efficiency, and the construction period of rapid excavation of the ultra-deep vertical shaft horizontal tunnel 1 is stably guaranteed.

[0043] In summary, the ultra-deep vertical shaft conversion gangue metering and loading device and its construction method provided by the embodiments of the present invention require no manual slag removal or auxiliary alignment during the entire slag loading process. Only one operator is needed to independently complete all operations such as metering bucket flipping, unloading, and resetting. This achieves continuous slag discharge cycle with single-person operation, rapid loading, and rapid lifting, solving the problems of low efficiency, high manpower consumption, and time-consuming bucket downtime in traditional slag discharge methods. It provides an efficient, safe, and economical solution for single-heading shaft excavation.
