Description

Technical Field

[0001] This invention belongs to the technical field of inclined shaft excavation and construction of power generation water diversion tunnels, specifically relating to a rapid slag removal device and method for water diversion inclined shafts. Background Technology

[0002] Conventional hydropower is not only a renewable and environmentally friendly source of electricity, but it also plays a positive role in reducing carbon dioxide emissions and air pollution, and preventing global warming. A conventional hydropower station consists of a reservoir, a water intake system, a powerhouse system, and a tailrace system. The water intake system comprises an inlet gate well, an upper water intake tunnel, an inclined water intake shaft, and a lower water intake tunnel.

[0003] Existing methods for removing slag from inclined shafts typically involve either direct slag removal using a steep-angle muck loader or slag removal using rail-mounted mine cars. Using a steep-angle muck loader requires significant equipment investment, as the loader itself is heavy and necessitates the use of a large-capacity winch for lifting. Furthermore, the inclined shaft angle must be less than 30°, as larger angles increase construction risks. The limited space in the inclined shaft also prevents complete removal of rock and slag from the working face, requiring manual cleaning. Using rail-mounted mine cars requires laying a section of track for each layer of the inclined shaft excavation, resulting in significant track investment, high difficulty in track laying, and high safety risks. Additionally, the track near the working face needs to be dismantled after slag removal, which is time-consuming and labor-intensive. Therefore, a rapid slag removal device and method for inclined shafts is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rapid slag removal device for a water diversion inclined shaft, which addresses the shortcomings of the prior art. The device has a reasonable structural design and a simple construction method. By equipping the slag removal vehicle with a rubber wheel travel mechanism and a rail wheel travel mechanism, the amount of rail laying work can be effectively reduced. Furthermore, the automatic unloading system can reduce the cumbersome construction procedures for slag removal in the inclined shaft, shorten the slag removal time, effectively improve construction efficiency, reduce construction safety risks, and effectively solve the problem of rail installation and removal at the working face during the excavation of the inclined shaft.

The slag removal vehicle includes a vehicle body, a hopper rotatably mounted on the vehicle body, a rubber wheel traveling mechanism located at the bottom of the vehicle body for traveling on the inclined section of the inclined shaft, and a track wheel traveling mechanism located at the bottom of the vehicle body and cooperating with the upper curved section track system. The upper curved section track system includes a track support structure and a track disposed on the upper part of the track support structure. The track gradually slopes upward from the end closer to the straight section to the end farther away from the straight section. The unloading system includes two gears respectively installed on both sides of the unloading hopper and two unloading racks symmetrically arranged on the upper part of the track support structure away from the inclined straight section. On the two unloading racks, racks that cooperate with the gears are installed on the side that is close to each other. The slag removal vehicle traction and lifting system includes a winch installed on the upper level section, and the wire rope of the winch is connected to the vehicle body.

[0006] The above-mentioned rapid slag removal device for a water diversion inclined shaft is characterized in that: the vehicle body includes a chassis and two side supports symmetrically arranged on the left and right sides of the chassis; the two sides of the unloading hopper are rotatably connected to the two side supports through a rotating shaft; the two rotating shafts are coaxially arranged; and the two gears are respectively installed on the two rotating shafts.

[0007] The above-mentioned rapid slag removal device for a water diversion inclined well is characterized in that: the rubber wheel traveling mechanism includes three rubber wheels, the track wheel traveling mechanism includes four track wheels, and the bottom of the track wheels is arranged higher than the bottom of the rubber wheels.

[0008] The above-mentioned rapid slag removal device for a water diversion inclined shaft is characterized in that: the vehicle body is provided with a retaining ring for connecting the wire rope of the winch.

[0009] The above-mentioned rapid slag removal device for a water diversion inclined well is characterized in that: the track includes two guide rails symmetrically arranged on the upper part of both sides of the track support structure, the guide rail includes an arc guide rail section and an inclined straight guide rail section connected to the upper end of the arc guide rail section, the lower end of the arc guide rail section is tangent to the inclined straight section, and the upper end of the arc guide rail section is tangent to the inclined straight guide rail section.

[0010] The above-mentioned rapid slag removal device for a water diversion inclined well is characterized in that: the track support structure includes two track support frames symmetrically arranged on both sides of the upper bend section, each track support frame includes multiple inclined supports with successively increasing lengths, a scissor brace is provided between two adjacent inclined supports, and a transverse support for track erection is provided at the upper end of each inclined support.

[0011] The above-mentioned rapid slag removal device for a water diversion inclined well is characterized in that: a guide roller for guiding the rubber wheel traveling mechanism is provided at one end of the track support structure near the inclined straight section.

[0012] The above-mentioned rapid slag removal device for a water diversion inclined shaft is characterized in that: the unloading frame includes two columns arranged sequentially along the extension direction of the track, a longitudinal connecting rod is connected between the upper ends of the two columns, a rack mounting frame is provided on one side of the longitudinal connecting rod, and the rack is fixed to the bottom of the rack mounting frame.

[0013] The above-mentioned rapid slag removal device for a water diversion inclined well is characterized in that: a winch mounting bracket for installing a winch is provided on the upper horizontal section.

[0014] Meanwhile, this invention also discloses a method for rapid slag removal from a water diversion inclined well, characterized by the following steps: Step 1: Lowering and loading the slag discharge car: The drum of the drive winch is reversed to lower the wire rope. Under its own weight and inertia, the slag discharge car moves sequentially along the track and the inclined and straight sections to the working face, and the unloading hopper of the slag discharge car is filled with stone slag. Step 2, Lifting the slag discharge car: Drive the winch drum to rotate forward, so that the slag discharge car gradually rises at a constant speed along the inclined straight section under the traction of the wire rope and relying on the rubber wheel walking mechanism. When the slag discharge car moves to the junction of the inclined straight section and the upper curved section, control the winch and reduce the walking speed of the slag discharge car, so that the slag discharge car gradually rises at a constant speed along the track under the traction of the wire rope and relying on the track wheel walking mechanism until the slag discharge car moves to the unloading frame position. Step 3: Automatic slag discharge from the slag truck: The drum of the drive winch rotates forward, causing the slag truck to continue to rise under the traction of the wire rope. The gears on both sides of the unloading hopper mesh with the racks on the two unloading frames respectively. As the slag truck continues to rise, the racks force the gears to rotate, thereby causing the unloading hopper to flip and dump the stone slag into the slag transport truck below, completing the automatic slag discharge. Step 4: Repeat steps 1 to 3 until the slag from the inclined shaft face is completely removed.

[0015] Compared with the prior art, the present invention has the following advantages: 1. By setting a rubber wheel traveling mechanism and a rail wheel traveling mechanism at the bottom of the vehicle body, the slag removal vehicle can alternately switch between the rubber wheel traveling mechanism and the rail wheel traveling mechanism on the inclined straight section and the upper curved section of the track. Therefore, it is not necessary to lay the track on the inclined straight section, which can eliminate the safety risks of laying the track on the inclined straight section, and can ensure the slag removal construction of the inclined shaft and reduce the track construction cost.

[0016] 2. This invention rotatably mounts the unloading hopper on the vehicle body and sets a gear on each side of the unloading hopper. On the two unloading racks, racks that mesh with the gears are installed on the adjacent sides of the racks. When the slag discharge vehicle rises to the position of the unloading rack, the racks force the gears to rotate as the slag discharge vehicle continues to rise, thereby causing the unloading hopper to flip and automatically discharge slag. This can effectively improve construction efficiency, ensure the quality of slag discharge from the inclined shaft, and reduce the construction cost of slag discharge from the inclined shaft.

[0017] In summary, the present invention has a reasonable structural design and a simple construction method. By equipping the muck truck with both rubber wheel and rail wheel travel mechanisms, it can effectively reduce the amount of track laying work. Furthermore, the automatic unloading system can reduce the cumbersome construction procedures for muck removal in inclined shafts, shorten the muck removal time, effectively improve construction efficiency, reduce construction safety risks, and effectively solve the problem of track installation and removal at the working face during inclined shaft excavation.

Detailed Implementation

[0027] like Figures 1 to 7 The device shown is a rapid slag removal device for a water diversion inclined shaft, including a slag removal car, a unloading system for automatically unloading the slag removal car, an upper curved section track system set in the upper curved section of the inclined shaft, and a slag removal car traction and lifting system set in the upper horizontal section of the inclined shaft. The slag removal vehicle includes a vehicle body 1, a hopper 2 rotatably mounted on the vehicle body 1, a rubber wheel traveling mechanism located at the bottom of the vehicle body 1 for traveling on the inclined section of the inclined shaft, and a track wheel traveling mechanism located at the bottom of the vehicle body 1 and cooperating with the upper curved section track system. The upper curved section track system includes a track support structure and a track disposed on the upper part of the track support structure. The track gradually slopes upward from the end closer to the straight section to the end farther away from the straight section. The unloading system includes two gears 14 respectively installed on both sides of the unloading hopper 2 and two unloading racks 13 symmetrically arranged on the upper part of the track support structure away from the inclined straight section. On the two unloading racks 13, racks 15 that cooperate with the gears 14 are installed on the side closest to each other. The slag removal vehicle traction and lifting system includes a winch 6 installed on the upper level section, and the wire rope of the winch 6 is connected to the vehicle body 1.

[0028] In actual use, by setting a rubber wheel travel mechanism and a rail wheel travel mechanism at the bottom of the vehicle body 1, the slag removal vehicle can switch between the rubber wheel travel mechanism and the rail wheel travel mechanism on the inclined straight section and the upper curved section of the track. Therefore, it is not necessary to lay the track on the inclined straight section, which can eliminate the safety risks of laying the track on the inclined straight section, and can ensure the slag removal construction of the inclined shaft and reduce the track construction cost.

[0029] It should be noted that by rotatably mounting the unloading hopper 2 on the vehicle body 1 and setting a gear on each side of the unloading hopper 2, and installing racks 15 that cooperate with the gears 14 on the adjacent sides of the two unloading racks 13, when the slag discharge car rises to the position of the unloading rack 13, as the slag discharge car continues to rise, the racks 15 force the gears 14 to rotate, thereby causing the unloading hopper 2 to flip and automatically discharge slag, which can effectively improve construction efficiency, at the same time ensure the quality of slag discharge from the inclined shaft, and reduce the construction cost of slag discharge from the inclined shaft.

[0030] In practice, the slag removal vehicle traction and lifting system is designed with a suitable winch based on stress calculations. The slag removal vehicle itself has no power system and uses the winch to pull it up and down the inclined shaft.

[0031] In practice, the gear 14 needs to be inspected more frequently during use to prevent wear of the gear 14 from causing it to be unable to mesh with the rack 15, which would prevent the slag car from automatically unloading. During the use of the slag car, it is necessary to strengthen the inspection during the process to prevent the slag car from derailing due to track deformation or wheel deformation.

[0032] In practice, the different walking modes of the muck truck are intended to reduce the amount of track laying work. After the inclined shaft is excavated, the straight and inclined sections of the muck truck's walking channel are leveled by sprayed concrete and smoothly connected to the upper curved section of the track.

[0033] In this embodiment, the vehicle body 1 includes a vehicle chassis 1-1 and two side supports 1-2 symmetrically arranged on the left and right sides of the vehicle chassis 1-1. The two sides of the unloading hopper 2 are rotatably connected to the two side supports 1-2 through a rotating shaft. The two rotating shafts are coaxially arranged, and the two gears 14 are respectively installed on the two rotating shafts.

[0034] In actual use, the unloading hopper 2 is fixedly connected to the rotating shaft, and a bearing is provided between the rotating shaft and the side support 1-2 to facilitate the rotation of the rotating shaft relative to the side support 1-2.

[0035] It should be noted that the rotating installation of the unloading hopper 2 also ensures that even on a 45° slope, the discharge port of the unloading hopper 2 will always be vertically upward under the action of gravity, thus avoiding slag leakage.

[0036] In specific implementation, the chassis 1-1 includes a central rectangular frame and two U-shaped frames symmetrically arranged on the front and rear sides of the central rectangular frame. The side supports 1-2 are isosceles triangular support plates. The two side supports 1-2 are respectively installed on the left and right sides of the central rectangular frame. The two sides of the unloading hopper 2 are rotatably connected to the two side supports 1-2 near the top corners through a rotating shaft.

[0037] In this embodiment, the rubber wheel traveling mechanism includes three rubber wheels 3, and the track wheel traveling mechanism includes four track wheels 4, with the bottom of the track wheels 4 positioned higher than the bottom of the rubber wheels 3.

[0038] In actual use, all three rubber wheels 3 are φ80cm rubber wheels, and the three rubber wheels 3 are distributed in a triangle. One rubber wheel 3 is set on the U-shaped frame at the front end of the vehicle body 1, which is the traction end. Two rubber wheels 3 are set on the U-shaped frame at the rear end of the vehicle body 1. The lateral distance between the two rubber wheels 3 at the rear end of the vehicle body 1 is 2.05m, and the longitudinal distance between the rubber wheel 3 at the front end of the vehicle body 1 and the rubber wheel 3 at the rear end of the vehicle body 1 is 2.5m.

[0039] In specific implementation, the track wheel 4 adopts a φ15cm "L" shaped single-sided steel track wheel, and the long side of the track wheel 4 is set inside the guide rail 8. Two track wheels 4 are set on each of the two U-shaped frames of the car body 1. The lateral distance between the two track wheels 4 at the front end of the car body 1 and the two track wheels 4 at the rear end of the car body 1 is 1.3m, and the longitudinal distance between the track wheels 4 at the front end and the track wheels 4 at the rear end of the car body 1 is 2.4m.

[0040] It should be noted that when the muck truck travels on the inclined and straight sections, it uses rubber wheels 3. When it is guided by the guide rollers 12 to travel on the track, the muck truck uses track wheels 4 to travel, and the rubber wheels 3 are suspended in the air.

[0041] In this embodiment, the vehicle body 1 is provided with a retaining ring 5 for connecting the wire rope of the winch 6.

[0042] In actual use, the retaining ring 5 is located on the upper front side of the vehicle body 1.

[0043] In practice, a portal frame is installed on the U-shaped frame at the front of the vehicle body 1, the retaining ring 5 is installed on the upper part of the portal frame, and the rubber wheel 3 at the front of the vehicle body 1 is installed below the portal frame.

[0044] In this embodiment, the track includes two guide rails 8 symmetrically arranged on the upper part of both sides of the track support structure. The guide rail 8 includes an arc guide rail segment 8-1 and an inclined straight guide rail segment 8-2 connected to the upper end of the arc guide rail segment 8-1. The lower end of the arc guide rail segment 8-1 is tangent to the inclined straight segment, and the upper end of the arc guide rail segment 8-1 is tangent to the inclined straight guide rail segment 8-2.

[0045] In actual use, the inclination angle of the inclined shaft is 45 degrees, and the inclination angle of the inclined straight guide rail section 8-2 is 20 degrees.

[0046] In practice, the radius of the arc guide rail section 8-1 is 10m and its central angle is 42 degrees, and the length of the inclined straight guide rail section 8-2 is 5.456m.

[0047] In practice, guide rail 8 is made of 18# I-beam steel.

[0048] like Figure 3 and Figure 4 As shown in this embodiment, the track support structure includes two track support frames symmetrically arranged on both sides of the upper curve section. Each track support frame includes multiple inclined supports 9 with successively increasing lengths. A scissor brace 11 is provided between two adjacent inclined supports 9. A transverse support 10 for track mounting is provided at the upper end of each inclined support 9.

[0049] In actual use, both the inclined support 9 and the transverse support 10 are made of HW150 steel. The track smoothly connects with the inclined and straight sections, and the guide rollers ensure that the slag discharge car travels smoothly onto the designated track. In specific implementation, a fixed pulley 16 is provided on the transverse support 10 at one end of the track support structure near the upper flat section. The fixed pulley 16 serves two purposes: first, to stop the slag car, and second, to drive the wire rope of the winch 6. The track has a net width of 1.3m, and the distance between the two track support frames below the track is 1.8m, which allows small slag transport vehicles to receive materials below.

[0050] It should be noted that the scissor brace 11 is made of φ25 three-stage threaded rod. The scissor brace 11 is welded and fixed to the diagonal support 9. The single-sided welding is 10d and the double-sided welding is 5d. The guide rail 8 is fully welded to the transverse support 10.

[0051] In this embodiment, a guide roller 12 for guiding the rubber wheel traveling mechanism is provided at one end of the track support structure near the inclined straight section.

[0052] In actual use, by setting guide rollers 12 on the track support structure, the slag discharge car can smoothly switch between the inclined and straight sections and the track.

[0053] In specific implementation, when the guide roller 12 needs to be installed on the track support structure, at the installation position of the guide roller 12, that is, at the position where the straight section and the upper curved section meet, a limiting block is respectively set between the corresponding transverse support 10 and the two guide rails 8. The guide roller 12 is installed on the corresponding transverse support 10 through the roller bracket, and the top of the guide roller 12 is not higher than the bottom of the guide rail 8. The guide roller 12 is located between the two limiting blocks.

[0054] like Figure 5 and Figure 6 As shown, in this embodiment, the unloading rack 13 includes two columns 13-1 arranged sequentially along the extension direction of the track. A longitudinal connecting rod 13-2 is connected between the upper ends of the two columns 13-1. A rack mounting bracket 13-3 is provided on one side of the longitudinal connecting rod 13-2, and the rack 15 is fixed to the bottom of the rack mounting bracket 13-3.

[0055] In actual use, the longitudinal connecting rod 13-2 is connected between the inner sides of the two columns 13-1, and the rack mounting bracket 13-3 is an I-beam welded to the inner side of the longitudinal connecting rod 13-2. The rack mounting bracket 13-3 and the longitudinal connecting rod 13-2 are parallel to each other.

[0056] It should be noted that the distance between the two unloading racks 13 is 2.5m.

[0057] In practice, column 13-1 is installed at an angle, and column 13-1 is perpendicular to longitudinal connecting rod 13-2. Longitudinal connecting rod 13-2 is parallel to inclined straight guide rail section 8-2.

[0058] like Figure 1 and Figure 2 As shown in this embodiment, a winch mounting bracket 7 for installing the winch 6 is provided on the upper flat section.

[0059] In actual use, the winch mounting bracket 7 includes two rows of columns, with multiple horizontal I-beams on the two rows of columns, multiple vertical I-beams on the multiple horizontal I-beams, and an installation platform for the winch 6 to be installed on the multiple vertical I-beams.

[0060] In practice, two winches 6 are used: one winch 6 serves as the working winch, and the other winch 6 serves as the backup winch to ensure construction safety.

[0061] like Figure 1 , Figure 3 and Figure 5 The method for rapid slag removal from a water diversion inclined well, as shown, includes the following steps: Step 1: Lowering and Loading the Muck Car: The drum of the drive winch 6 reverses, lowering the wire rope. Under its own weight and inertia, the muck car moves sequentially along the track and the inclined / straight section to the working face, filling the unloading hopper 2 of the muck car with stone chips. Figure 1 As shown; Step 2, Lifting the Muck Cart: The drum of the drive winch 6 rotates clockwise, causing the muck cart to gradually rise at a constant speed along the inclined section under the traction of the wire rope and relying on the rubber wheel travel mechanism. Figure 3 As shown, when the slag discharge car moves to the junction of the inclined straight section and the upward curved section, the winch 6 is controlled and the traveling speed of the slag discharge car is reduced, so that the slag discharge car, under the traction of the wire rope, gradually rises at a constant speed along the track by relying on the track wheel traveling mechanism, until the slag discharge car moves to the position of the unloading frame 13, as shown. Figure 5 As shown; Step 3: Automatic slag discharge from the slag truck: The drum of the drive winch 6 rotates forward, causing the slag truck to continue to rise under the traction of the wire rope. The gears 14 on both sides of the unloading hopper 2 mesh with the racks 15 on the two unloading frames 13 respectively. When the slag truck continues to rise, the racks 15 force the gears 14 to rotate. The gears 14 are fixed on the rotating shaft, causing the rotating shaft to rotate, which in turn causes the unloading hopper 2, which is fixedly connected to the rotating shaft, to flip and dump the stone slag into the slag transport vehicle 17 below, thus completing the automatic slag discharge. Step 4: Repeat steps 1 to 3 until the slag from the inclined shaft face is completely removed.

[0062] In specific implementation, in step one, the muck truck itself has no power system. The muck truck is powered by the winch 6 to move up and down the inclined shaft. When the muck truck moves to the face of the inclined shaft, it moves downward by its own gravity and inertia. At this time, the winch 6 needs to lower the wire rope at a constant speed. When the muck truck reaches the end of the shotcrete at the face, it needs to stop lowering the wire rope and provide tension to prevent the muck truck from moving onto the exposed surrounding rock, which would cause the muck truck to change direction and thus be unable to enter the track.

[0063] It should be noted that after the muck truck is loaded with slag by the small backhoe at the working face, the winch 6 starts to lift it at a constant speed. When the muck truck travels to the junction of the straight section and the upper curve section, the speed of the muck truck needs to be reduced. After traveling to the track by the guide roller, it is strictly forbidden for people to stand near the track to avoid stone chips falling and injuring them. After the muck truck stops below the unloading frame 13, it is slowly lifted to the end point of the unloading frame 13.

[0064] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
