[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a traveling apparatus for a tow train of a fire extinguisher (referred to as a fire extinguisher) that moves on a rail laid on the ground side of a coke oven.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 5 (a) and 5 (b), a vehicle frame is attached to bearings 4 and 4 of axles 3 and 3 of front and rear wheels 2 and 2 'supported on a rail 14 via rubber springs a and a. 1 (chassis) is provided so as to be movable up and down, and a speed reducer 9 'and an axle 3, are provided at the lower part of a base plate 5 provided at the upper end of the vehicle frame 1 in the middle part between the front and rear wheels 2, 2 and 2', 2 'on both sides. The DC motor 10 ′ was provided in the direction parallel to the motor 3, and the opening p was provided in the base plate 5 immediately above the motor 10 ′ to perform replacement or repair work of the motor 10 ′.
[0003]
This is necessary because the electric motor 10 ′ provided under the base plate 5 can be replaced or repaired from above the base plate 5.
[0004]
Therefore, it is necessary to set the height of the base plate 5 as low as possible, and a thin rubber spring a is used for the striation between the bearings 4 and 4 of the axles 3 and 3 and the vehicle frame 1. It is easily affected by the heat of the coke oven, has a short life of 4 to 5 years, has a large influence on vibrations on in-vehicle electrical and mechanical products, has many replacements, and the brake is shown in Fig. 5 (b). As shown in FIG. 4, the brake shoe is replaced and adjusted by wear using the wheel brake b, and there are many maintenance parts.
[0005]
Moreover, the opening p is dangerous for human work on the base plate 5, and there is a defect that the work area and the arrangement area of the equipment cannot be taken sufficiently.
[0006]
In addition, the distance (wheel base) between the front and rear wheels 2 and 2 'cannot be made longer than the relationship of the arrangement of the driving equipment. There was a problem of being big.
[0007]
[Problems to be solved by the invention]
The present invention is excellent in cushioning of the vehicle frame and the base plate, has little replacement of the spring due to the influence of heat, has little influence of vibration, simplifies the brake, and does not need to form an opening on the top surface of the base plate. There are few restrictions on the arrangement of equipment, and the wheelbase can be taken long, so the movement of the axle load and pitching due to horizontal traction force are reduced, and the swinging of the vehicle frame or base plate during running of the carriage can be freely absorbed to the drive equipment support plate. The purpose is to reduce the impact.
[0008]
[Means for Solving the Problems]
In the present invention extinguishing train vertically movable and supported through a spring bearing of the front and rear wheels of the axles of vehicle frame, formed by arranging the devices by providing a base plate on the upper surface of the vehicle frame for achieving the above object, one end portion Place a support plate that fixes the motor on the other end and a speed reducer connected to the motor on the other end with a rotary joint on the side of the vehicle frame so that both ends are in the front-rear direction. One end of the axle extended to the vehicle is connected to the output portion of the speed reducer orthogonal to the axle, while one end of the support plate is suspended from a side projection provided on the vehicle frame or the base plate. One end of the support plate is connected to a side projection provided on the vehicle frame or the base plate so as to be swingable by a suspension plate and a pin, and is suspended so as to absorb the swing of the vehicle frame and the base plate during traveling. Traveling device in fire-fighting train according to the first invention
It is comprised by the traveling apparatus in the fire extinguisher of the said 1st or 2nd invention which formed the brake in the said rotation joint.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
A coke guide vehicle runs on the platform of the coke oven, and a fire extinguisher runs on a rail 14 laid on the ground 22 (FIG. 1) below the platform.
[0010]
The electric locomotive of the fire extinguisher (locomotive), that is, the fire train 6, the vehicle frame 1 (chassis) is attached to the guide guides 15, 15 on the bearings 4, 4 of the axles 3, 3 of the front and rear wheels 2, 2 ′ supported on the rail 14. A base plate 5 is provided as a single body on the upper surface of the vehicle frame 1.
[0011]
Between the bearings 4 and 4 and the base plate 5, coil springs 7 and 7 are interposed on both sides of the axle 3, and the base plate 5 is supported by the force of the springs 7 and 7 so as to be movable up and down.
[0012]
One end of the front and rear axles 3, 3 is extended 3 'to the side of the vehicle frame 1. As shown in FIG. 2, the extension direction is opposite in the front-rear direction, but may be the same direction.
[0013]
The extension portion 3 'is connected to an output portion 9 "of a speed reducer 9 provided in a direction orthogonal to the axles 3 and 3 on a support plate 11 disposed on a side portion of the vehicle frame 1. The output portion 9" is a boss of a reduction gear. The extension 3 ′ is fitted to the boss via a key or fitted to the friction coupling ring.
[0014]
The travel drive device 8 is formed by a speed reducer 9 and an inverter-controlled AC motor 10, and is formed by connecting an output shaft of the motor 10 and an input shaft of the speed reducer 9 with a common rotary shaft joint 12, A disk plate 13 ′ is provided on the rotary shaft joint 12, and the disk brake 13 of the rotary shaft joint 12 is formed by clamping both surfaces of the disk plate 13 ′ with electromagnetic clamping pieces 13 ″, 13 ″. However, other brakes can be used instead of the disc brake 13.
[0015]
One end of the support plate 11 of the travel drive device 8 formed in this way is between the front and rear wheels 2, 2 ′ or in front of them, the side projection 5 ′ provided on the vehicle frame or the base plate 5 and the support plate 11. The bearing plates 16 and 16 (Fig. 3 (a)) provided on the suspension plate are suspended by a suspension plate 17 loosely attached by small-diameter pins 19 and 19 so that the other end of the support plate 11 can be reduced. The speed reducer 9 is supported on the rail 14 via the bearing 4, the extension 3 ′ and the wheel 2 or 2 ′.
[0016]
Large-diameter holes 18 and 18 are formed in the upper and lower ends of the suspension plate 17, and a small-diameter pin 19 inserted between the upper and lower bearing plates 16 and 16 is inserted into the large-diameter holes 18 and 18 to form a universal bearing. Further, the gap between the bearing plates 16 and 16 is made larger than the thickness of the suspension plate 17, and the suspension plate 17 is supported by the bearing plates 16 and 16 so as to be swingable in the front-rear direction and the width direction. Support is called loose attachment.
[0017]
In FIG. 3 (b), 20 is a relief window of the motor portion protruding from the suspension plate 17, and 21 is an emergency rail brake provided between the front and rear wheels 2 and 2 '.
[0018]
【The invention's effect】
Since the present invention is configured as described above, a fire extinguisher with excellent heat resistance and good cushioning properties can be obtained, the influence of vibration on the mounted equipment is small, the wheelbase can be taken long, and the traveling performance is excellent. Since there is no need to project the opening, there are effects that workability on the base plate and device arrangement restrictions are small, and maintenance of the travel drive device is easy.
[0019]
In addition, the support plate of the speed reducer can absorb the swing of the vehicle frame and the base plate during travel, so that the travel drive apparatus can be made to respond to the above swing without difficulty, and the brake is connected to the speed reducer and the motor of the travel drive apparatus. There is an advantage that maintenance and inspection can be simplified because there are few parts of the brake mechanism.
