DETAILED DESCRIPTION OF THE INVENTION

[0001]

INDUSTRIAL APPLICABILITY The present invention is used in an underground excavation work such as a shield construction method and a mining work in a sloping shaft of an inclined shaft connecting an excavation site and a shaft base near the surface of the earth.
The present invention relates to a transportation facility for steel vehicles that transport soil and equipment.

[0002]

2. Description of the Related Art Conventional slant shaft transportation equipment is a winch device installed on a horizontal shaft base near the surface of the earth where a traveling rail is laid in the shaft of the slant shaft and a steel car with a plurality of connected vehicles runs on it. The steel car was towed by a wire and climbed in the direction of the vertical shaft, and it was driven by its own weight to the excavation site using the slope of the traveling rail of the inclined shaft. Since the shaft base is horizontal and the steel car does not move in the direction of the excavation site, another pilot car that can run by itself on the traveling rail is installed, and a person rides on the pilot car to drive the steel car at the position where the inclination of the inclined shaft begins. I was pushing the steel car to push. According to this operation method, a person rides on a pilot vehicle in a recumbent state and moves through a narrow slope tunnel, which is dangerous, and in some cases, a narrow slope can not accommodate a person. Further, when the wire of the winch device (hoisting device) for driving the steel wheel moves the steel wheel to the inclined shaft, the pulling force of the wire fluctuates and the wire is in a disordered winding state.

[0003]

SUMMARY OF THE INVENTION The present invention solves these problems of the prior art, allows a steel car to be operated safely without a passenger, and also prevents the winch device (hoisting device) of the steel car from winding irregularly. It is to provide a slant shaft transportation facility that can be prevented.

[0004]

[Means for Solving the Problems] The constitution of the present invention which has solved the above problems is as follows: 1) A steel car traveling rail is installed in a tunnel connecting an underground excavation site and a horizontal shaft base close to the surface with an inclined shaft. In a slant shaft transportation facility in which a steel car is run on the steel car traveling rail and the steel car is towed along the steel car traveling rail toward the vertical shaft base by the winch device at the vertical shaft base, A trolley rail and a wire are installed side by side along a steel car running rail part, and a trolley car that pushes and propels the lower part of the steel car or an accessory car connected with the steel car in the direction of the inclined shaft is run on the trolley rail. A torque motor in which wires arranged in parallel along the vehicle traveling rail are returned at the position of the boundary with the inclined shaft, the ends of the returned wires are connected to the trolley car, and the other end of the wires is provided in the shaft base. Drive Wound in the auxiliary winch, and steel wheel or steel wheel by moving the trolley car inclined shaft direction at the same auxiliary winch

The wire for pulling the trolley wheel of the present invention may be an endless wire, and the wire may be wound by a winch in both directions so that the trolley wheel can be pulled directly in the winch direction. One-sided,
Both are included.

[0006]

In the present invention, the trolley rail and the wire are installed in parallel along the traveling rail of the steel car in the horizontal portion of the shaft base.
A trolley car that pushes a steel car or an attached car connected to the steel car is pulled by a wire on the trolley rail in the direction of the inclined shaft. The wire is wound up and unwound by an auxiliary winch driven by a torque motor. Further, the wires are arranged in parallel along the traveling rail of the steel car and return at the position of the boundary with the inclined shaft, and the ends of the returned wires are connected to the trolley car. Therefore, when moving the steel car from the horizontal part of the shaft base to the excavation site, the auxiliary winch using the torque motor is operated to wind up the wire, and the trolley car bound to the wire is moved toward the excavation site (oblique shaft part). Move the trolley car to the steel car or
Slope of an inclined shaft portion by pressing the bottom of the forming the supplementary wheel inclined steel wheel
Move to the beginning of the slope . Moving trolley car
Since the auxiliary winch uses a torque motor, the propulsive force of the steel wheel can be kept constant, and the wire of the winch device (hoisting device) for driving the steel wheel acts on the wire with a predetermined constant pulling force, which causes the winch for driving the steel wheel. It prevents the wires of the device from winding randomly. The propulsion of the steel car in the inclined shaft part depends on the weight of the slope. Further, the movement from the excavation site of the steel car to the horizontal portion of the shaft base is performed by wire pulling by the winch device (hoisting device) for driving the steel car.

FIG. 9 is an explanatory diagram showing a shaft pressing state by the trolley vehicle of the embodiment, and FIG. 9 is an explanatory diagram showing a steel wheel pushing state of the trolley vehicle of the embodiment. In the figure, 1 is a shield excavation site, 2 is an inclined shaft, 3 is a shaft base, 4 is an underground tunnel, 5 is a winch device for driving a steel car, 6 is a steel car running rail, and 7 is a steel car. A towing wire, 8 is a sheave for diverting the wire, 9 is a steel car, 10 is a pilot car of an accessory car connected to the head of the steel car, 10a is its shaft, 11 is a trolley car, and 11a is a trolley car. Wheels, 11b are pusher plates erected on the top of the trolley wheel 11 that pushes the axle 10a of the pilot wheel 10 to move the steel wheel 9, 12 is a trolley rail, 13 is a pulling wire for driving the trolley wheel 11, 14 Is a connecting portion of the wire 13 with the trolley wheel 11, 15 is an auxiliary winch using a torque motor (not shown) for driving the wire 13, 16 and 17 are sheaves of the wire 13, 18 is a steel car run preventer, 19 is the surface of the earth, 20 Operation control unit of the steel wheel-trolley cars, 21 a stopper provided on the upstream side of the inclined shaft 2 of the trolley car 11, is 22, 23 is a wire guide roller.

In this embodiment, a plurality of steel wheels 9 are connected to each other,
Further, the unmanned pilot vehicle 10 is connected to the tip of the railcar and runs on the steel vehicle traveling rail 6. After the soil discharged from the excavation site 1 is stored in the steel car 9, when the winch device 5 is operated by the operation control unit 20 of the shaft base 3, the steel car 9 moves along the steel car running rail 6 with the wire 7 It is pulled by and climbs the inclined shaft 2 and is moved to the horizontal portion of the shaft base 3. The pilot vehicle enters the vertical shaft base 3 and proceeds toward the waiting trolley vehicle 11. The stationary trolley vehicle 11 will sneak into the lower part of the moving pilot vehicle 10, and the axle 10a of the pilot vehicle 10 will hit the pusher plate 11b of the stationary trolley vehicle 11 and will pull with the pilot vehicle 10. The trolley vehicle 11 is pushed in a state of sneaking into the lower portion of the pilot vehicle 10 and moved toward the auxiliary winch 15 of the shaft base 3. At this time, the torque motor of the auxiliary winch 15 pulls the wire 13 with a constant pulling force and acts as a resistance force for urging the pilot vehicle 10 in the direction of the inclined shaft to prevent the wire 7 of the winch device 5 from being irregularly wound. At the vertical shaft base, the soil discharged from the steel wheel 9 is lifted to the surface 19 by means such as a vertical conveyor (not shown). Next, when moving the empty steel car 9 from the shaft base 3 to the excavation site 1, when the auxiliary winch 15 using a torque motor (not shown) is operated, the wire 13 is stretched horizontally. The trolley wheel 11 that is horizontally wound around the sheaves 16 and 17 and attached to the end of the wire 13 is mounted on the trolley rail 1 by its traveling wheels 11a.
2, it moves in the direction of the inclined shaft 2 and dives into the lower part of the pilot car 10 at the front of the steel car 9, and its axle 10a hits the pusher plate 11b erected on the upper part of the trolley car 11, and the axle 10a of the pilot car 10 Auxiliary winch 1
The pilot vehicle 10 and the steel wheel 9 are moved in the direction of the inclined shaft 2 by pushing with a predetermined wire propulsive force with a constant torque of the torque motor 5 (see FIGS. 7, 8 and 9). This is a steel car 9 with an inclined shaft 2
It is pushed and propelled until it moves to the inclined steel car traveling rail 6 part. The trolley vehicle 11 hits the stopper 21 and stops, and the pilot vehicle 10 and the steel wheel 9 separate from the trolley vehicle 11 and travel by themselves on a slope. FIG. 9 shows a state in which the pilot car 10 and the steel car 9 are pushed by the trolley car 11. When the steel car 9 moves to the inclined steel car traveling rail 6, it propels itself by its own weight and travels on its own, moving to the excavation site 1 at a required speed while being speed-controlled by the wire 7. Thus, since the auxiliary winch 15 of the wire 13 for driving the trolley wheel 11 uses the torque motor, the propulsive force for moving the steel wheel 9 can be maintained at a predetermined constant value, and thus the wire of the main winch device 5 can be maintained. The wire can be fed out while giving a certain amount of tightness without slackening, and it is possible to prevent irregular winding.

[0009]

As described above, according to the present invention, since the steel car is pushed and propelled by the wire-driven trolley car, the steel car can be propelled unmanned in a horizontal shaft base, which is safe. The device is also small, simple, and inexpensive to manufacture. Further, by using a torque motor for the auxiliary winch of the wire, a constant tension force can be applied to the wire of the winch device driven by the steel wheel, and the wire is prevented from becoming irregularly wound. Especially, in the structure where the trolley car sneaks into the bottom of the steel car or accessory car and the pusher plate that comes into contact with the axle is provided, the size can be made extremely small, and the space occupied at the shaft pit is reduced so that it does not hinder the work. it can.
