The above-mentioned conventional multipurpose scrap dismantling machine can work well in the dismantling work of the aircraft itself, the train itself, and the building itself, but is used for the dismantling work of the interior of the aircraft, the train, etc. and the interior of the building. It was too big and too heavy for me. On the other hand, when dismantling an aircraft, a train, or the like, there is an increasing need for a lightweight dismantling work vehicle for interiors that can be suitably used for interior dismantling work in which existing interior objects are separated and removed.

That is, in the dismantling work of the interior of an aircraft or train, an operation boom that is small and lightweight and can penetrate into the room of an aircraft or train, and can lie down on a powerful work pencher to tear off the interior. There is an increasing need for a demolition work vehicle equipped with a self-propelled vehicle body.

In particular, in aircraft and some trains, for the purpose of weight reduction, a plurality of annular frame materials arranged side by side, a plurality of stringer materials connected to adjacent frame materials, and the frame material and the stringer material are covered. It has a semi-monocoque structure composed of outer panel materials, and since the floor of the guest room itself is installed on the frame material itself, it is composed of a similar frame and the floor plate material that covers it, so heavy machinery that has invaded the room. Is vulnerable to support.

An object of the present invention is to obtain a compact and lightweight demolition work vehicle equipped with a pencher at the tip of an undulating actuating boom, and further, it is possible to disperse the weight of the demolition work vehicle even on a fragile floor. It has the effect of being able to obtain a lightweight dismantling work vehicle.

It is a top view which shows the structure of one Example of the lightweight dismantling work vehicle for interior of this invention, and includes a partially enlarged view. It is a side view of FIG. It is a front view of FIG. It is explanatory drawing which shows the operation of the lightweight dismantling work vehicle for interior of FIG.

In the present invention, the dismantling work vehicle is provided with an actuating boom mounted on a self-propelled vehicle so as to be able to turn and lie down, and a dismantling work pencher attached to the tip of the actuating boom and opened and closed by remote operation. It is provided with one or more dispersion base means for distributing the weight of the self-propelled vehicle arranged around the self-propelled vehicle, and the distribution base means is vertically attached to the outside of the circumference of the self-propelled vehicle. The support arm portion is provided, a base attached to the tip end portion of the support arm portion, and a pressing means for pressing the base downward so as to be able to release the pressure. This makes it possible to distribute the weight of the demolition work platform even on a fragile floor.

That is, the weight-reduced dismantling work vehicle for interiors of the present invention is provided with a dispersion base means for performing interior dismantling work even on a fragile floor. As a specific dispersion base means, the support arm portion that is telescopically attached to the outside of the circumference of the self-propelled vehicle, the base attached to the tip of the support arm portion, and the base can be released from pressing. It is provided with a pressing means for pressing downward. By providing the dispersion base means, the weight of the self-propelled vehicle provided with the actuating boom and the pencher for dismantling work can be dispersed.

In a preferred embodiment of the present invention, the dispersion base means is extensiblely arranged at the front or the rear of the self-propelled vehicle. As a result, the work can be performed while gradually moving the dismantling work vehicle while dismantling the interior.

The base of the present invention may be one that is installed at the tip of a support arm portion that is stretchably attached to the outside of the periphery of the self-propelled vehicle, and the base is moved by the stretchable support arm portion. After that, the base may be pressed against the floor base material below by the pressing means to disperse the weight of the dismantling work vehicle not only to the self-propelled vehicle but also to the base. As the support arm portion of the present invention, a long arm portion may be attached to the dismantling work vehicle so as to be movable in the longitudinal direction, or the inner arm portion of the nesting type arm portion may be moved in and out of the outer arm portion. It may be stretchable.

As the pressing means of the present invention, the support arm portion may be made to be able to lie down by flood control or a motor, or the support arm portion may be arranged between the support arm portion and the base and the base with respect to the height position of the support arm portion. The height position of the may be changed. The dismantling work pencher of the present invention has a replaceable tip, a tapered pinching pencher for easy picking of the interior, and a flat tip or flat tip for easy scraping of the interior. Various pencil tips such as a peeling pencher equipped with claws may be prepared in advance and replaced according to the object of dismantling work.

The base of the present invention may be one that is attached to the tip of the support arm portion and is pressed downward by the pressing means to disperse the weight of the dismantling work vehicle not only to the self-propelled vehicle but also to the base. As the floor base material pressed by the base, a semi-monocoque structure of an aircraft or some trains is assumed. That is, in aircraft and some trains, an annular frame material arranged side by side in the longitudinal direction of the body forming the cross-sectional shape of the cylinder of the body, a stringer material connecting these annular frame materials, and an annular frame material. It is composed of an outer plate material that connects the stringer material and the stringer material from the outside.

The annular frame material is a primary structural member having a cross-sectional shape of a body. For example, frame materials having a Z-shaped cross section are arranged at intervals of 20 inches (= 50.8 cm) on the body of a Boeing 747. A passenger cabin is formed by constructing a floor base material in the body. This floor base material is also composed of a frame and a floor board material that covers it for weight reduction. In order to fix it to the body, the frame of the floor base material and the frame material of the body are joined and fixed.

In the present invention, as described above, in order to obtain a lightweight dismantling work vehicle for interiors suitable for interior dismantling work of separating and removing existing interior parts of an aircraft having a semi-monocoque structure or a part of a train, a preferred embodiment is used. The dismantling work vehicle is further provided with a base sensor for detecting the frame material arranged on the floor base material around the lower side of the self-propelled vehicle, and more preferably, the base sensor is provided on the base.

As a result, after confirming the skeleton of the floor base material composed of the skeleton supported by the frame material of the semi-monocoque structure and the floor board material covering it with the base sensor, the base is moved to this skeleton part to reduce the weight. Since it can be dispersed, the weight of the self-propelled vehicle can be dispersed and the dismantling work can be performed even on a fragile floor.

The base sensor of the present invention may be any one that can recognize the skeleton of the floor base material composed of the skeleton and the floor plate material covering the skeleton from the surface of the floor base material. For example, the presence or absence of a skeleton may be determined by electrically reading the change in the capacitance of the floor base material. Since the capacitance changes when the density is different, if the base sensor moves the surface of the floor base material and approaches the skeleton, the electrical state of the wall surface will be different, so it is sufficient to detect the position. ..

The base sensor may be detected while extending in the traveling direction of the self-propelled vehicle, but is preferably attached to a base installed on a support arm portion that can move around the self-propelled vehicle. When the skeleton of the floor base material is detected while moving, the dismantling work can be safely performed by placing the base on the detected skeleton and distributing the weight.

FIG. 1 is a plan view showing a configuration of an embodiment of a lightweight dismantling work vehicle for interior use of the present invention, and includes a partially enlarged view. FIG. 2 is a side view of FIG. FIG. 3 is a front view of FIG. FIG. 4 is an explanatory view showing the operation of the lightweight dismantling work platform for interior use of FIG.

As shown in FIGS. 1 to 3, the interior lightweight dismantling work vehicle 10 of this embodiment is mainly carried into a passenger plane, a passenger car, or the like having a semi-monocoque structure, and the interior is separated and removed. Used for dismantling work. At this time, a small and lightweight self-propelled vehicle 11 that can be carried in even on a fragile floor is used, and is at least 1.5 tons or less, more preferably 1 ton or less.

The self-propelled vehicle 11 can travel on a rubber endless track 14 for weight reduction and weight distribution, and a turning stage 12 driven by a motor output and a driver who operates a dismantling work vehicle 10 are on board. It includes a driver's seat 13 and a hydraulically actuated boom 16 having a pencher 20 for dismantling work operated by flood control from the hydraulic engine 15 at the tip. The flood control engine 15 that drives the flood control boom 16 is equipped with a high output engine.

The hydraulically actuated boom 16 of the dismantling work vehicle 10 is folded up to the work site. The pencher 20 for dismantling work at the tip of the boom 16 is capable of swinging and rotating the boom 16 and rotating around the axis, and these operations are hydraulically or electrically operated from the cockpit 13. It is done by remote control of.

Although the driver's seat 13 of this embodiment is installed in the dismantling work vehicle 10 in an open state, the driver's seat 13 is provided with clean air so as to cover the periphery of the driver's seat 13 and maintain the airtight state as a cabin. A clean air donating means that can be provided in a pressurized state (a pressure state higher than the atmospheric pressure) may be provided therein. This configuration is effective for removing asbestos in the passenger cars of some trains.

In addition, as one of the means for supplying clean air, an oxygen cylinder (not shown) used when moving to the asbestos removal work site can be mounted in the dismantling work vehicle, and as another means for providing clean air. Before arriving at the asbestos removal work site, an air supply hose as an air supply type air supply means installed by an operator outside the vehicle may be arranged.

In this embodiment, the dismantling work vehicle 10 is operated from the cockpit 13, but as another embodiment, a camera that captures the work target and an operation command from a place far away from the work place are used. A remote control means for transmitting to each drive means may be provided separately, and the remote control may be performed while viewing the image of the camera at a place other than the work site.

The dismantling work pencher 20 sandwiches an existing interior object with a pair of sandwiching arm portions of a drive sandwiching arm portion 22 and a fixed sandwiching arm portion 23 that are driven to open and close around a fulcrum 21 by the flood control from the hydraulic engine 15. The interior parts sandwiched by the operation of the hydraulically actuated boom 16 and the like are separated and torn apart and removed. It should be noted that the tip of the dismantling pencher 20 can be replaced, and the tip of the illustrated interior can be easily picked up from the tapered pinching pencher, and the tip can be flattened or flattened to make it easy to scrape the interior. Various pencil tips such as a peeling pencher equipped with claws may be prepared in advance and replaced according to the object of dismantling work.

The weight applied to the floor base material on which the demolition work vehicle is riding changes when the interior is torn or peeled off. In particular, when the interior object attached to the floor base material is torn upward, this tearing force increases in addition to the weight of the floor base material on which the demolition work vehicle is mounted. On the other hand, the weight of the dismantling work platform is applied to the floor base material below the pair of rubber tracks 14.

Regarding this weight distribution, in this embodiment, a pair of distribution base means 30 including a total of four support arm portions 31 and a base 32 are provided at the front portion and the rear portion of the self-propelled vehicle. The arm portion of the horizontal portion of the L-shaped support arm portion 31 can be expanded and contracted in the front-rear direction in a nested manner by flood control, and the tip portion of the arm portion of the vertical portion hydraulically presses the height position of the base 32 as a pressing means. It can be changed. Further, the base sensor 33 is arranged on the lower surface of the base 32 having a circular flat surface installed at the lower end of the support arm portion 31.

As shown in the enlarged view of FIG. 1, the base sensor 33 arranges the sensor group 34 so as to be orthogonal to the extension direction of the support arm portion 31, and each sensor group 34 changes the capacitance of the floor base material. It is read electrically to determine the presence or absence of a skeleton. This makes it possible to disperse the weight of the demolition work platform even if the floor base material is fragile.

The detection result of the base sensor 33 is displayed on the operation panel (not shown) of the driver's seat 13, and the operator can operate the base 32 so as to move it on the frame of the floor base material. Further, more preferably, the control means for automatically moving the center of the base 32 to the central portion of the width of the frame of the floor base material detected by controlling the extension direction of each support arm portion 31 according to the detection result. May be provided.

More specifically, as shown in FIG. 4, the interior lightweight dismantling work vehicle 10 of the present embodiment is carried into the passenger cabin of a passenger aircraft to perform interior dismantling work of separating and removing interior objects. The floor base material 40 in the passenger cabin of the passenger aircraft is composed of a frame 41 arranged substantially evenly and a floor board material 42 covering the frame 41.

As shown in FIG. a, the base 32 of each pair of dispersion base means 30 at the front and the rear of the interior lightweight dismantling work vehicle 10 is placed on the frame 41 of the floor base material 40. In this state, the existing interior in the guest room is torn off with the dismantling work pencher 20 to perform the dismantling work. In this case, since the base 32 is placed on the frame 41 of the floor base material 40, the weight-reducing dismantling work vehicle 10 for interior is dispersed, and the change in weight due to the dismantling work is also well dispersed.

While finishing the dismantling work in the state of FIG. a, the dismantling work vehicle 10 is gradually moved forward. At this time, the moving speed of the dismantling work vehicle 10 and the expansion / contraction speed of the support arm portion 31 are set to the same speed, and the positions of the front and rear bases 32 are not moved. When the front of the dismantling work vehicle 10 approaches the front base 32, the movement of the dismantling work vehicle 10 is stopped.

After the dismantling work vehicle 10 is stopped, the pressing of the base 32 of one of the front dispersion base means 30 against the floor base material 40 is stopped and slightly raised, and the support arm portion 31 is extended forward. At that time, the base sensor 33 of the extended base 32 is detected, the frame 41 of the front floor base material 40 is detected by a control means (not shown), the width start position is recorded, and the width start position is further extended and detected. After detecting the width end position where the frame 41 is no longer detected and determining the intermediate position between the width start position and the width end position, the support arm portion 31 is expanded and contracted to set the center position of the base 32 to the intermediate position. Move control is also performed.

Next, the pressing of the base 32 of the one rear dispersion base means 30 against the floor base material 40 is stopped and slightly raised, and the support arm portion 31 is contracted forward. At that time, the ground sensor 33 of the base 32 that has been shrunk is detected, the frame 41 of the front floor base material 40 is detected by a control means (not shown), the width start position is recorded, and the width start position is further extended and detected. After detecting the width end position where the frame 41 is no longer detected and determining the intermediate position between the width start position and the width end position, the support arm portion 31 is expanded and contracted to set the center position of the base 32 to the intermediate position. Move control is also performed.

Next, the base 32 of the other dispersion base means 30 in the front portion also stops pressing on the floor base material 40 and is slightly raised to extend the support arm portion 31 forward. At that time, the base sensor 33 of the extended base 32 is detected, the frame 41 of the front floor base material 40 is detected by a control means (not shown), the width start position is recorded, and the width start position is further extended and detected. After detecting the width end position where the frame 41 is no longer detected and determining the intermediate position between the width start position and the width end position, the support arm portion 31 is expanded and contracted to set the center position of the base 32 to the intermediate position. Move control is also performed.

Finally, the base 32 of the other dispersion base means 30 at the rear is also similarly stopped from pressing against the floor base material 40 and slightly raised, and the support arm portion 31 is contracted forward. At that time, the ground sensor 33 of the base 32 that has been shrunk is detected, the frame 41 of the front floor base material 40 is detected by a control means (not shown), the width start position is recorded, and the width start position is further extended and detected. After detecting the width end position where the frame 41 is no longer detected and determining the intermediate position between the width start position and the width end position, the support arm portion 31 is expanded and contracted to set the center position of the base 32 to the intermediate position. The movement is also controlled, and the result is as shown in FIG. 4b. By moving the four dispersion base means 30 one by one, the weight can be reliably dispersed, and even if the floor base material is fragile, the weight of the dismantling work vehicle can be reliably dispersed. Become.

Even in the state shown in Fig. B, the existing interior in the guest room is torn off with the dismantling work pencher 20 to perform the dismantling work. In this case, since the base 32 is placed on the frame 41 of the floor base material 40, the weight-reducing dismantling work vehicle 10 for interior is dispersed, and the change in weight due to the dismantling work is also well dispersed. As described above, by distributing the weight, the dismantling work can be safely performed. In this embodiment, the expansion / contraction direction of the base 32 is along the support arm portion 31, but a pair of bases can be moved by a motor or the like in the direction in which the base 32 intersects the support arm portion 31. It is possible to change the distance of the table 32, and it is also possible to stably distribute the weight.
