Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to box dismantling equipment used for dismantling boxes such as railway vehicles such as trains, passenger cars and Shinkansen trains, and containers such as containers.

[Background of the invention]

Conventionally, the dismantling of boxes, ie, containers, railway cars, etc., has been carried out manually using gas cutting or plasma cutting means, but this method has the following various defects. The biggest one is
During cutting, the work environment deteriorates due to the generation of toxic gases, and pollution to the surrounding area is a problem. Furthermore, because the car body is not very rigid, the red-hot cutting part gets stuck after gas cutting, which significantly reduces work efficiency.Furthermore, the car body is characterized by the fact that most of the body cross sections are made up of inner and outer plates. There is a space between the plate and the work efficiency is low, especially in plasma cutting because it is not possible to cut both the front and back sides at the same time, and the inside and outside must be cut separately.

The disassembly processing method by cutting is a method in which it is easier to separate and reuse the disassembled board materials by material after the dismantling process, compared to the processing method that crushes them with a press machine. Conventionally, the work efficiency was low and it was time-consuming.

[Purpose of the invention]

The details of each component used in FIG. 1 will be explained below with reference to FIGS. 2 to 11.

First, details of the side cutting machine 3 will be explained using FIG. 2. The circular saw 2a is driven by a hydraulic motor 10 via a spindle head 8 and a coupling 9. The spindle head 8 has a transverse frame 11
The cutting depth of the circular saw 2a is adjusted by the screw 12 and the hydraulic motor 13. Furthermore, this transverse frame 11 has a screw 15 provided on the column 14, a hydraulic motor 1
6, the cutter can be raised and set at the appropriate height of the car body for cutting. Furthermore, this column 14 travels on a rail 20 by a rack 23 having a pinion 19 attached to the drive rail 20 via a hydraulic motor 17 and a speed reducer 18. Note that each hydraulic motor is driven and controlled by a hydraulic unit 22 mounted on the traveling frame 21. Further, power supply and control commands to this device are performed via a curtain cable.

The operation of the side cutting machine 3 shown in FIG. 2 is as follows. That is, when the vehicle body to be dismantled is ready for cutting, the hydraulic motor 17 is driven;
Drive to the cutting start point at the end of the vehicle. At the same time, the hydraulic motor 16 is driven to move up and down to the set cutting height. After completing these operations, the hydraulic motor 13
is driven so that the circular saw 2a moves horizontally so that the appropriate cutting depth is reached. During or after this lateral movement is completed, the hydraulic motor 10 is driven to rotate the circular saw 2a and start cutting. Once the cutting is complete,
Evacuate by doing the opposite of the above.

Next, details of the gable cutting machine 4 will be explained using FIG. 3.

The circular saw 2b is driven by a hydraulic motor 27 via a spindle head 25 and a coupling 26. Further, the gable cutting machine is constructed so that it can be rotated 90 degrees by a hydraulic cylinder 38 in order to perform horizontal cutting and vertical cutting. These heads are connected to a pinion 31 and a reducer 3 on a rack 30 on a transverse beam 29.
The hydraulic motor 33 provided through the motor 2 is driven to move horizontally. Furthermore, this transverse beam 29 is raised and lowered by rotating a screw 36 on a guide rail 35 provided on a gate-shaped frame 34.
The screws 36 are connected by a shaft 37 for left and right synchronization, and are driven by a hydraulic motor 40 via a chain 38 and a reduction gear 39.

Further, in the gate-type frame, a wheel 41 attached to the frame is moved by a hydraulic motor 4 on the rail 20.
3. It travels via a speed reducer 44 and a pinion 45, and a rack 43 provided on the side of the rail. These hydraulic motors are driven and controlled by a hydraulic unit 46 and a control panel 47 mounted on the gate frame 34. External control and power supply is carried out via curtain cables.

The operation of the gable cutting machine 4 shown in FIG. 3 is as follows. That is, when it becomes possible to cut into the car body to be dismantled, more specifically, when the setting of each support device is completed, the cutting machine 4 travels to the position where the circular saw 2b has the appropriate depth of cut, and At the same time, it moves up and down to the cutting position. Running is hydraulic motor 43
It is driven by a hydraulic motor 40 for lifting and lowering. The circular saw 2b performs horizontal cutting and vertical cutting. This horizontal and vertical switching is performed by expanding and contracting the hydraulic cylinder 38. The circular saw 26 is
It rotates by being driven by a hydraulic motor 27. The rampant
This is done by driving the hydraulic motor 33. After the cutting is completed, the robot is evacuated by performing the reverse operation.

Next, using FIG. 4, the roof, side support device 5
1 and 52 will be explained in detail. In this embodiment, a roof support device 51 and two side support devices 52 are installed.
It is installed on two traveling frames 67. The hydraulic motor 53 provided on the traveling frame 67 rotates the wheels 56 via the reducer 54 and the shaft 55.
It runs on the rail 58 of the runway girder 57 of the support device. This movement allows the vehicle to move above the position where the vehicle body should be supported.

The roof support device 51 includes a telescoping frame 59 and a holding frame 60 to support the roof structure from above and below, and these are driven and operated by hydraulic cylinders 61 and 62, respectively. Furthermore, these frames are bolted to an inner column 63 and are guided by bushes within a guide frame 64 fixed to a traveling frame 67 to move up and down. The lifting and lowering operations are performed by expanding and contracting a hydraulic cylinder 66 attached to the upper part of the outer column 65.

The side support device 52 also includes an inner presser frame 68 for pressing the side structure from the inside, and an outer presser frame 69 attached to a claw for pressing and obtaining support from the outside. It operates by These are inner column 71
It is bolted to the frame 67 and moves up and down guided by bushes in the traversing frame 72 that traverses on rails provided on the traversing frame 67. Lifting and lowering operations are performed using outer column 7.
This is done by expanding and contracting a hydraulic cylinder 74 attached to the upper part of 3. Further, the traversing frame 72 is designed to be traversed by a hydraulic cylinder 75 and supported at an appropriate position on the vehicle body. All these operations are hydraulically driven, and the hydraulic unit 76,
The drive is controlled by a control panel 77.

Explain the movement. To set the roof support device 51, with the telescopic frame 59 retracted, it is moved to align with the air conditioning hole position of the vehicle body, and then lowered. The telescopic frame is extended and raised at the limit of elevation, and the roof structure is supported with a slight force, stopped, and pressed from above by the cylinder 62 of the upper presser frame 60. After cutting in this state and passing through the main support point, it is strongly supported at an appropriate location to widen the cut. Once the roof structure has been cut and removed as described above, the side support device 52
After adjusting the travel to the position of the window frame, move the frame 7
2 at the outermost position of the vehicle body, and lower it in this state. At the lifting/lowering limit, the hydraulic cylinder 75 is driven to traverse inward, and the lateral movement is stopped by a detection signal from a contact limit SW 78 attached to the outer holding frame 69. As a result, the external presser frame 69
The lower end of the claw will fit into the window frame, so the hydraulic cylinder 7
4, the side support device 52 is raised to slightly support the side structure. Next, the internal presser frame 68 is closed using the hydraulic cylinder 70. The method of providing strong support while cutting with a cutting machine is the same as roof support. To release it from the roof support and side support, just do the reverse of the above.

Next, details of the gable support device 5 will be explained using FIGS. 5 and 6.

The gable support device 5 includes an inner presser frame 81 and an outer presser frame 82 for pressing the gable structure from the inside and outside, and is pressed by a hydraulic cylinder 83. Further, the inner presser frame 81 is provided with a telescoping arm 84 operated by a hydraulic cylinder 9 to widen the cut by pushing both side structures outward during vertical cutting of the end structure. These frames are
The inner column 85 is attached to the outer column 87 via a bush in a guide frame 86, and is raised and lowered by a cylinder 88. These are mounted on a traveling frame 89, rotated by an axle 93 via a hydraulic motor 90, a feed reducer 91, and a shaft 92, and run on a rail 58 on a runway girder 57. All these operations are hydraulically driven and controlled by a hydraulic unit 96 and a control panel 97. This support device also provides strong support after passing the cutting point of the cutting machine, improving the cutting performance of the circular saw. The operation of this gable support device 5 is as follows. That is, first, the hydraulic motor 90 is driven to travel and move the support device to an appropriate position. Next, with the inner presser frame 81 open, the cylinder 88 is driven and lowered. At the lifting/lowering limit, the hydraulic motor 90 is driven again to travel, and the limit switch attached to the retainer frame 82 is used to move it until contact with the structure is confirmed. As a result, the claw at the lower end of the outer holding frame 82 enters the opening for the communication passage on the end face, so that the column is raised and supported by the claw of the outer holding frame 82. At this point, the inner presser frame 82 is closed and firmly supported from the inside and outside by the hydraulic cylinder 98.

In addition, like a container, there are openings into which the telescopic frame 59 of the roof support device 51, the claws at the lower end of the outer presser frame 69 of the side support device 52, and the claws at the lower end of the outer presser frame 82 of the end support device 5 can be inserted. For those without one, open the opening using gas cutting, etc. in advance.

Next, details of the vehicle body receiving device 6 will be explained using FIGS. 7 to 9.

The car body support device 6 is used to prevent deformation of the car body during cutting, to make the car body to be cut parallel to the cutting machine, and to prevent the body from falling outside when the car body is folded down after cutting. It has the following functions. The vehicle body receiving device fixes the base 101 with foundation bolts at four locations on each side of the vehicle body at locations parallel to the vehicle body loading rail.

After carrying in the vehicle body to be dismantled, the receiving frame for placing the vehicle body on the vehicle body receiving frame 102 can move horizontally with respect to the base via a slide member 103, and a cylinder 104 attached to the base 101
Extend and press the structure. The same device is provided at opposite positions, and by pushing together, it attempts to achieve parallelism, and at the same time prevents the car body from shifting or deforming in the horizontal direction during cutting. Furthermore, after centering, the spring 99 returns to the center position. Furthermore, this device has a chain 10 connected to the main body base 101 in order to prevent deformation of the vehicle body due to the lifting force of the support device, etc.
Cylinder 105 suspended at 0, sheave 106,
A hook 108 is attached to the structure by a rope 107. Moreover, this changes the attachment position to the structure, and furthermore, when the structure is folded down after cutting, the cylinder 109 is extended and contracted to prevent the structure from falling out, and the stopper arm 110 prevents the structure from falling.

Next, details of the positioning device 6a will be explained using FIG. 10. The positioning device 6a has the functions of positioning the vehicle body in the traveling direction when the vehicle body is carried in, and of preventing the end structure from coming off when folding down the cut end structure. A stopper arm 111 is kept in a raised state when the vehicle enters the vehicle, and when the vehicle enters the vehicle, it hits the stopper, its energy is absorbed by the shock absorber 112, and the spring 113 returns it to a fixed position to stop the vehicle at the fixed position. After the positioning is completed, the cylinder 114 is retracted, the roller 115 is moved, and the stopper is lowered. Furthermore, since the stopper arm 111 may be tilted when carrying the vehicle body, it is supported by a pin 116. Furthermore, when the wife structure is brought down, this stopper arm 1
This is to raise 11 and prevent the structure from falling.
These are attached to frame 117.

Next, using FIG. 11, the end stopper device 6b
Explain the details. The gable release prevention device 6b moves the roller 122 and raises and lowers the arm 121 by expanding and contracting the cylinder 120, and keeps the arm in a raised state when the gable is brought down to prevent the structure from falling. These are attached to a frame 123 and fixed on the ground.
