る破砕機に関するものである。Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a crusher for demolishing concrete structures such as buildings, and in particular, the present invention relates to a crusher for demolishing concrete structures such as buildings. The present invention relates to a crusher that can crush a structure while fixedly supporting it, and can appear or move using its own blades using the structure as a foothold.
(従来の技術)
一般に、ビル等の構造物を解体するための破砕機として

から成るものがある。(Prior art) In general, a crusher for demolishing structures such as buildings has a rotatable base and a crushing member provided at the front of the base so as to be able to rise and fall and has a clamping claw or the like at the tip. Some consist of a movable boom.
このタイプの破砕機で、低層階のビルを解体する場合は

tこ過程を繰り返すことでビル等の構造物の解体が行え
る。When demolishing a low-rise building with this type of crusher, you can crush walls, columns, and other structures from the top of the structure by adding a long boom even if the base is fixed on the ground. On the other hand, in the demolition of medium- and high-rise buildings, the crusher is hoisted to the top of the structure using a large crane and fixed, and the structure is crushed from around the feet (and once the appropriate area has been destroyed, it is removed from the ground). Use a crane to lift the equipment from the
By self-propelling, it is moved to the low position where it has finished breaking down, fixed, and resumes crushing work within the reach of the boom. Buildings and other structures can be demolished by repeating this process.
(発明が解決しようとする問題点)
低層階で小型のビルの解体で破砕機を地上に置いて行え

だけの最小限の移動作業だけで足るが、市街地で隣合う
構造物が近接していると地上に破砕機の設置空間が確保
できず、後者の中高層ビル解体のよう1ζピルの最上階
に装置を吊り上げる必要がでてくる。(Problem to be solved by the invention) When demolition of a small building with low floors can be carried out by placing the crusher on the ground, only a minimum amount of transportation work is required, such as loading and unloading it on site using a transport device such as a truck. However, in urban areas where adjacent structures are close together, it is not possible to secure installation space for the crusher on the ground, and it becomes necessary to hoist the device to the top floor of the 1ζ pill, as in the latter case when demolishing medium-to-high-rise buildings.
後者の中高層ビルの解体では、大型重量物である破砕機

が把握しに<<、単に作業進行の妨げになるばかりでは
なく危険を伴う。In the latter case, when demolishing mid-to-high-rise buildings, lifting the crusher, which is a large and heavy object, to a high place is difficult and dangerous.
Each time the equipment is moved while crushing the scaffolding, the same difficult lifting work as above is required using a large crane on the ground. Moreover, the strength of the structure must be strong enough to sufficiently support the heavy crusher, and if this is insufficient, auxiliary support means are required. In addition, since the workers proceed with the crushing work while visually checking from the cockpit installed on the crusher, it is difficult to grasp the overall structure and crushing situation, which simply hinders the progress of the work. Not only is it dangerous, but it is also dangerous.
更には、破砕機が、高位置から崩し終えた低位置に自走
して移動する場合には、足場の不安定による危険が伴っ
た。Furthermore, when the crusher moves by itself from a high position to a low position where it has finished crushing, there is a risk of unstable footing.

できろ破砕機を提供することにある。Therefore, it is an object of the present invention to be able to climb or move to a structure using a self-blade by using the structure such as a wall or pillar of a building as a foothold, and to fix the device to the structure while It is an object of the present invention to provide a crusher which can perform crushing operations simultaneously and can carry out these moving and crushing operations remotely.

It consists of a bending/extending drive cylinder, and a crushing part that is swingably provided at the free end of the boom and has a clamping member that can be opened and closed,
The crushing member is rotatably attached to the swinging member, holding the swinging member and the clamping member, which are pivoted to the boom and driven to swing by operating a drive cylinder. and a clamping member.

ができる。(Function) The clamping member of the clamping part is driven to open and close by a hydraulic system, etc., and does not clamp objects to be clamped, such as walls and columns of building structures. By increasing the force of clamping the object, the object can be crushed. In addition, it is possible to retract the boom 1.11 by 1 stroke while holding the object to be clamped, or by appropriately adjusting the bending/extending drive cylinder between the 1 retracting boom or the drive cylinders at the two free ends of the telescopic boom. By operating the telescopic boom and controlling the posture of the crushing section, one crushing section can be fixed to the object to be clamped while the other crushing section can be moved within a radius defined by the entire length of the telescopic boom. Can be done. The thus-moved crushed portion is placed facing the structure at an appropriate position and held between the clamping members. Using the thus fixedly supported crushing part as a fulcrum, the clamping member of the one crushing part is released, and the telescopic boom and each drive cylinder are operated again to move the opened crushing part to an arbitrary location. By repeating this operation, the device can be moved over the structure using its own blades and the desired crushing operation can be performed at any location.

砕機が提供できる。(Effects of the Invention) As described above, according to the present invention, the telescopic booms are connected so as to be bendable and extendable, and the crushing portions having the clamping members are provided at each free end. By controlling the attitude of the crushing section with respect to each boom, it is possible to move over structures such as pills with its own blade, and while one crushing section is fixed to the structure, the other crushing section can crush it. The work efficiency of structure demolition is dramatically improved. Moreover, since remote control is possible, the dangers associated with dismantling work can be avoided, and the dismantled state can be checked from a distance, so it is expected that the work will proceed more efficiently. Furthermore,
Since it can be configured to be small and lightweight while still having sufficient crushing capacity, the hydraulic system that is the drive system for these components can be downsized, and since no load is placed on the scaffolding structure, there is no delay in reinforcing the scaffolding etc. No work required. In other words, if the reaction force for the crusher can be secured in the building's structures such as pillars, beams, and walls, it does not depend on the strength of the structure, so there is no need for complicated procedures such as strength calculations to support the crusher. . As described above, according to the present invention, it is possible to provide a crusher that is easy to handle, does not take up a lot of equipment space, and can be carried in and out using its own blades, providing excellent effects.
