Description

[Detailed Description of the Invention] The present invention relates to a concrete demolition device for crushing indoor partition walls of concrete buildings.

Conventionally, such concrete demolition equipment uses a hydraulic cylinder to compress and operate a pair of crushing pins that are placed opposite each other on a frame, and the concrete wall is successively crushed by the pressure between the opposing pins. At that time, the main body of the demolition machine is supported by a forklift at the work site and can be moved up and down and left and right as the demolition work progresses. Due to the shape of the machine itself, there are many parts that cannot be crushed, especially the corner parts of the wall, and since the movement of the demolition machine itself is linked to the movement of the forklift itself, the movement of the demolition machine in the vertical direction is dependent on the movement of the forklift. This can be done by simply lifting and lowering the lift, but the forklift itself has to be moved each time it is moved, even within a minute range, resulting in very poor work efficiency.

In view of these drawbacks, the present invention includes a dismantling machine main body in which a pair of frames, on which crushing pins are mounted facing each other, are connected to each other so as to be slidable forward and backward by a drive device;
It consists of a mounting mechanism section that attaches the disassembly machine main body to a support device such as a lifter, and the mounting section of the disassembly machine main body is mounted and supported so as to be freely movable forward and backward and rotatable relative to the ring-shaped housing of the mounting mechanism section. A concrete demolition device is provided, in which a pair of arms are disposed in parallel, the base end of which is fixed to a support device, and the housing is pivotally connected between the tips of the arms to form a parallel link mechanism. An embodiment of the present invention will be described below with reference to the drawings in order to overcome the drawbacks. 1 is a demolition device for crushing concrete, and includes a demolition machine body 2, a support device 3, and a mounting mechanism section 4. It is configured.

The cylinder 12 is supported by the outer wall 14 of the frame 5 by intervening tie rods 15, 15a between the cylinder 12 and the outer wall 14, and escape holes for the tie rods 15, 15a are provided in the inner wall 16 of the other frame 5a. 17,17
A plate 18 is installed, and a fitting hole 19 is formed in the center of the plate 18, and a nut 21 attached to the tip of the rod 20 of the cylinder 12 is fitted into the fitting hole 19. A rod 20 of a cylinder 12 is connected to the frame 5a by mating and fixing, so that the frame 5a can be controlled to slide horizontally with respect to the frame 5 by the operation of the cylinder 12.

The support device 3 has casters 22, 22a... on the lower surface.
A support 24 is erected on the upper surface of the machine base 23 on which a lift rod 25 is mounted, and a lift rod 25 is guided and supported on the support base 24 so as to be able to rise and fall freely.A drive motor 26 is mounted on the machine base 23, and a motor 2
A wire 28 wound around a pulley 27 attached to the column 6 is connected to a latch piece 30 at the lower end of the lift rod 25 via a pulley 29 fixed to the upper end of the support column 29. It is designed to control the elevation.

Next, the mounting mechanism section 4 will be explained.A pair of arms 32,
Shafts 33, 33 to which the base end of 32a can be attached and detached
The arm 32 is rotatably supported via a.
The other ends of the arms 32a are arranged parallel to each other, and a ring-shaped housing 34 is horizontally arranged between the tips, and the support pieces 35, 35a on both sides of the housing 34 are attached to and detached from the tips of the arms 32, 32a. The arms 32, 32a and the housing 34 constitute a parallel link mechanism 37, which is pivotally supported by shafts 36, 36a.

On the other hand, guide members 38, 3 are provided on the outer periphery of the mounting portion 9 of the demolition machine main body 2, and are in sliding contact with the inner periphery of the housing 34.
8a... to fit and support the demolition machine main body 2 with respect to the housing 34 so that it can rotate and move forward and backward, and stoppers 39, 39a... is detachably attached to the circumferential surface of the housing 34.

Next, to explain the operation of the concrete demolition device according to the present invention, the demolition machine main body 2 is supported by the support device 3 via the mounting mechanism section 4,
to position the concrete wall surface to be crushed between the pins 8 and 8a of the demolition machine main body 2,
When the cylinder 12 is moved forward by hydraulic pressure in such a state, as the frame 5a connected to the rod 20 side moves in the approaching direction with respect to the other frame 5, the pin 8a also moves in the same direction. The concrete wall surface is compressed between 8a and sequentially crushed, and if a load is applied to the demolition machine body 2 in the longitudinal and lateral directions, the demolition machine body 2 moves back and forth with respect to the housing 34 and the parallel link mechanism The left and right movement by 37 causes a follow-up operation and the overload is absorbed.

Then, the crushing process is carried out sequentially from the top to the bottom by moving the dismantling machine body 2 downward via the lift rod 25 by the operation of the drive motor 26, and the process to the bottom is shown in FIG. By manually rotating the demolition machine main body 2 relative to the housing 34 and changing the posture so that the pins 8 and 8a are on the lower side, it is possible to perform crushing treatment up to the bottom surface, and also to When processing the parts, the pins 8 and 8a are placed in contact with the wall by manually moving the demolition machine main body 2 horizontally and horizontally as shown in FIG. 3 using the parallel link mechanism 37 of the mounting mechanism section 4. After that, they are crushed in the same way.

In short, the present invention consists of a demolition machine main body 2 in which a pair of frames 5, 5a to which crushing pins 8, 8a are mounted facing each other are connected to each other so as to be slidable forward and backward by a drive device 10; It consists of a mounting mechanism section 4 that is mounted on a support device 3 such as a lifter,
Since the attachment part 9 of the demolition machine main body 2 is attached to the housing 34 of the mounting mechanism part 4 so that it can move forward and backward, the overload during the crushing process by the demolition machine main body 2 can be absorbed by the movement of the demolition machine main body 2 back and forth with respect to the mounting mechanism part 4. At least it is possible to prevent overload from acting on the support device 3, and furthermore, since the demolition machine main body 2 is rotatably mounted and supported by the ring-shaped housing 34, the demolition machine main body 2
