JPH108720A - Boom front end conveying hose right and left reciprocating movement and swiveling device of reciprocating movement device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To settle problems of safety and heavy labor of workers engaged in such work as a pulsatory and heavy-weight hose is held by two or three workers to move ceaselessly since they are engaged in the heavy labor on an unsteady place to work in the field of concrete conveying work in building and civil engineering work. SOLUTION: A reciprocating movement device is constituted of a link mechanism 10 fixing the front end of a hose with a metal fixture 12 and capable of being reciprocated right and left by bending a concrete conveying hose 11 mounted to the front end of a boom 2 of a concrete conveying pumper 1 with the boom 2. The tip of the front end of the hose can be changed to any direction by swiveling the device 7 itself, and ready mixed concrete can be placed in consonance with reciprocating movement and the movement of the whole boom.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention comprises a link mechanism capable of bending a ready-mixed concrete pumping hose attached to the foremost point of a boom of a ready-mixed concrete pumping pump truck with a boom, fixing a hose tip, and reciprocating left and right. By doing so, the front end of the tip hose can be changed in any direction, and the hose can reciprocate left and right.

2. Description of the Related Art Conventionally, in a concrete structure for construction and civil engineering work, when a ready-mixed concrete pump pump truck is used to pump ready-mixed concrete, a pumping hose is hung at the end of the boom, and the pumping hose is placed on reinforcing bars or on a formwork. At the forefront, he put a ready-mixed concrete while moving the hose with human power. This work requires skill, and because fresh concrete is being pumped through the hose, pulsation occurs due to this pumping force and the hose is constantly moving, and the weight of about 50 kg to about 120 kg is reduced by two people. The three workers, who are constantly working while moving, are referred to as technicians.They were forced to work hard in the instability of their feet, and heavy hoses moved over the reinforcing bars of the structure. At present, the arrangement of the reinforced reinforcing bars was disturbed.

[0003] The present invention solves the above-mentioned problems. An embodiment will be described below with reference to the drawings. FIG. 1 is a side view for explaining an embodiment of the present invention. Reference numeral 1 denotes a pump truck equipped with a concrete pump.
A boom 2 rotatably connected to the boom 2 is mounted. At the tip of the boom 2, a swinging device of a left-right reciprocating moving device and a reciprocating moving device of the most advanced pressure hose shown in FIGS. 2 and 3 is provided.
In connection 4, the motor connects 8 turning small gears and 5 reduces and drives with the large turning gear, connects the 7 base to the large turning gear 5, connects the hose movement guide 10 and the turning cylinder 9 to 7, The raw concrete pressure-feeding hose 11 connected to the hose moving guide 10 is fixed with the fixing bracket 12 and reciprocates right and left by the cylinder 9. Concrete is gradually poured into the concrete form in the state 13 and the whole movement is performed by the boom 2. do. Next to the horizontal position, when the vertical position of the concrete form 13 is reached, the motor 4 drives the large turning gear 5 with the small turning gear 8, the cylinder 9 connected to 7, the hose moving guide 10, and the fixture 12. Then, the direction of the ready-mixed concrete supply hose 11 is turned in the vertical direction, and the hose moving guide 10 is moved by the cylinder 9 so that the ready-mixed concrete supply hose 11 can be moved vertically along the formwork. The dotted line portion in FIG. 1 shows the state of movement.

[0004] In this way, it is possible to relieve heavy work in places where the feet are unstable and to carry out safe work. In addition, since the hose is not placed on the reinforcing bars and the formwork, the reinforcing bars are not disturbed and the mold is not disturbed. No disturbing frame structure
