JPH09125709A - Demolishing heavy machine having sprinkling function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To save labor in the demolishing operations and ensure safety by furnishing a water supply piping along an arm of a demolishing heavy machine, installing a water sprinkle nozzle at the foremost of the piping, and performing automatic sprinkling when the structure concerned is crushed by a nibbler so that sputter of the powder and dust is precluded. SOLUTION: A demolishing machine 1 has a bent arm 4, which is equipped at the tip with a nibbler 4 operated hydraulically, wherein a water supply piping 11 is installed along the arm 4, and at the foremost of the piping, a water sprinkle nozzle 10 is installed in such an arramgement that the nozzle hole faces always the place to be crushed. Accordingly the operator of the demolishing machine 1 can perform the sprinkling along with the demolishing works, which liberates from necessity for stationing of any specially devoted operator for sprinkling and also eliminates change in the arrangement so as to suit sprinkling. Thus the building demolishing works can be executed effectively and safely.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight dismounter capable of suppressing the generation of dust during the dismantling work of a reinforced concrete structure or the like.

[0002]

2. Description of the Related Art Conventionally, when crushing and dismantling a reinforced concrete structure, a dedicated watering operator has a watering nozzle connected to a high pressure hose to prevent a large amount of dust generated from scattering to the surrounding area. I had a (so-called high washer) in my hand and went near the crushing site to spray water around the crushing site.

[0003]

However, the conventional method as described above has the following problems.

[0004] A water sprinkling worker is required, and this sprinkling worker is on the crushed concrete debris,
Since the high-pressure sprinkler hose had to be routed on an unstable scaffold, it was a very dangerous work.

In order to avoid a direct hit of a crushed concrete piece, a sprinkling worker could not sufficiently approach the crushing site and could not sufficiently suppress dust scattering.

[0006] When the weight breaking machine moves from its crushing place to the next crushing place, it will be in a non-sprinkling state while the sprinkling worker is changing the hose, and work on an unstable scaffolding or the like. Therefore, it was not possible to catch up with the movement of the weight-removing machine, and dust was generated, causing trouble to the neighborhood.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to perform a water spraying work safely without requiring a worker who is exclusively engaged in water spraying, and at the crushing site. An object of the present invention is to provide a weight-removing machine having a watering function capable of constantly approaching and sufficiently preventing scattering of dust.

[0008]

In order to achieve the above-mentioned object, the present invention adds a watering function to the weight breaking machine itself,
The dismantling work and the sprinkling work can be performed integrally, and a sprinkling nozzle is provided at the tip of the arm of the weight breaking machine, and a water supply pipe for supplying water to the sprinkling nozzle is arranged along the arm. Characterize. The water supply pipe is introduced into the weight remover, and an opening / closing cock is provided in the cockpit of the weight remover so that the operator can freely operate the water spray and the water stop. In addition, the water supply unit is installed outside the weight-removing machine, and water in a water tank or the like is supplied to the water supply pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 shows a dismantling state by a weight dismounter according to the present invention. In FIG. 1, a weight breaking machine 1
Is mainly composed of a crawler type lower traveling structure 2, an upper revolving structure 3 having a driver's seat, etc., a two-stage arm 4, and a nibler 5 provided at the tip of this arm 4.

The arm 4 is composed of a first arm 4-1 on the distal end side and a second arm 4-2 on the proximal end side.
Has its base end attached to the tip of the second arm 4-2 so as to be tiltable in the vertical direction, and can be bent in the vertical direction by the hydraulic cylinder 6. The base end of the second arm 4-2 is attached to the upper swing body 3 so as to be vertically tiltable, and can be lifted up and down by the hydraulic cylinder 7.

The nibler 5 is composed of a tip portion 5A provided with a pair of gripping claws that can be opened and closed, and a base portion 5B provided with the tip portion 5A rotatably provided. The base portion 5B is the first arm 4-1. It is attached to the tip end so as to be tiltable, and is vertically tiltable by a hydraulic cylinder 8.

In the weight remover 1 having such a structure, the water spray nozzle 10 is provided in the nibler 5, the water supply pipe 11 of the water spray nozzle 10 is arranged along the arm 4, and the upper swing body 3 is provided.
Arrange to the inside. The watering nozzle 10 is the base 5 of the nibler 5.
It is attached to B through the column 12 and is arranged in parallel with the extending direction of the gripping claws of the nibler 5 so that the nozzle hole is always directed to the crushed portion.

The water supply pipe 11 is arranged in the upper revolving structure 3 and the water supply pipe 11-1 and the water supply pipe 11-2 which are attached to the first arm 4-1 and the second arm 4-2 via the columns 13, respectively. The water supply pipe 11-3 is provided, and the water sprinkling nozzle, the water supply pipe, and the water supply pipes are connected to each other by flexible pipes or hoses 14, so that they can be followed even when the arm or the like is bent.

An opening / closing cock (stop valve) 15 is provided in the water supply pipe 11-3 at the operator's seat of the weight-removing machine so that the operator can freely perform watering / stopping operations. In addition, in this water supply pipe 11-3,
A water supply pipe 16 from a water supply unit installed outside is connected so that water can be supplied from a water tank or the like.

In the above-mentioned structure, the operator of the weight breaker simply opens the opening / closing cock 15 to spray the water from the water spray nozzle 10 to spray water around the dismantling site at the same time as the dismantling work. As a result, the sprinkling work can be automatically performed at the same time as the dismantling work, the operator dedicated to the sprinkling is not required, and the safe water sprinkling work can be performed without any danger to the worker.

Further, when the weight breaking machine moves from the crushing place to the next crushing place, the sprinkler nozzle 10 and the water supply pipe 11 move together with the weight crusher, so that the conventional water spraying worker changes the hose. It is possible to eliminate the non-sprinkling state during the operation, and the sprinkling nozzle does not catch up with the movement of the weight breaking machine, and it is possible to reliably prevent the scattering of dust. Further, since the operator of the weight breaking machine does not have to wait for the change of sprinkling water as in the conventional case, the efficiency of the dismantling work is improved.

[0017]

Since the present invention has the above configuration, the following effects can be obtained.

(1) The operator of the weight dismantling machine can perform the water spraying work at the same time as the dismantling work, which eliminates the need for a worker dedicated to the water spraying, and saves labor and manpower. In addition, the danger to the water spraying worker as in the conventional case is completely eliminated, and the water spraying work can be safely performed.

(2) Water is always automatically sprinkled around the dismantling point, eliminating the conventional non-sprinkling condition when moving the weight dismantling machine or when changing the hose, and reliably preventing dust scattering can do.

(3) Since the operator of the weight breaking machine does not have to wait for the setup change of water sprinkling, the efficiency of the dismantling work is significantly improved.
