Abstract

The utility model provides a walking concrete boom conveyor with rotation landing leg, four landing legs of the platform on its walking chassis are rotation landing leg or two for rotation landing leg two in addition for fixed landing leg or two for rotating landing leg two in addition for flexible landing leg, adopt articulated connection and set up the rotation leg hydro-cylinder between the linking arm of rotation landing leg and the platform, work as the utility model discloses during operation, can rotate the rotation landing leg of platform to the position of the center of gyration of the axis of the linking arm of landing leg through the conveyer, the torsion that makes the linking arm receive is less, is difficult for damaging the linking arm, improve the stability of equipment during operation.

Description

Have the walking concrete arm conveyer that rotates supporting leg

Technical field

The utility model relates to a kind of walking concrete conveying equipment, especially has the walking concrete arm conveyer that rotates supporting leg.

Background technology

Four supporting legs of existing its chassis platform of walking concrete arm conveyer and the annexation of platform have such two kinds of structures:

(1) four supporting leg all adopts the oil cylinder of stretching one's legs to be connected with platform;

(2) adopt the oil cylinder of stretching one's legs to be connected between two supporting legs of platform one end and the platform, two supporting legs of the other end are fixed on the platform.

The weak point of these two kinds of structures is: the axis of the linking arm of supporting leg and platform is the centre of gyration by the concrete arm conveyer on the chassis not, make this conveyer bigger to the torsion of the linking arm generation of supporting leg and platform in when work, the easy damaged linking arm, the stability when also influencing equipment work.

Summary of the invention

In order to overcome the deficiency of existing walking concrete arm conveyer, the utility model provides a kind of walking concrete arm conveyer that rotates supporting leg that has, the linking arm of its supporting leg and platform can rotate, when work, the linking arm of supporting leg can be turned to the centre of gyration of its axis by conveyer, the torsion that linking arm is subjected to is less, easy damaged linking arm not, the stability the during work of raising equipment.

The walking concrete arm conveyer that rotates supporting leg that has that the utility model provides comprises walking type chassis and the concrete arm conveyer (1) that is installed on the walking type chassis, the structure of four supporting legs of the platform of walking type chassis (3) and the annexation of platform (3) is: be and rotate supporting leg (9), adopt between its linking arm (16) and the platform (3) to be articulated and connected and commentaries on classics leg oil cylinder (15) is set; Perhaps adopt between two of platform (3) one ends linking arms (16) that rotate supporting legs (9) and the platform (3) and be articulated and connected and commentaries on classics leg oil cylinder (15) be set and two fixed supporting legs (17) of the other end are fixed on the platform (3); Perhaps adopting between two of platform (3) one ends linking arms (16) that rotate supporting legs (9) and the platform (3) is articulated and connected and is provided with changes leg oil cylinder (15) and the setting oil cylinder (21) of stretching one's legs between the linking arm (22) of two telescopic outriggers (19) of the other end and the platform (3).

The beneficial effects of the utility model are: the rotation supporting leg (9) and the linking arm (16) thereof that are provided with support platform (3) on walking type chassis, when concrete arm conveyer (1) is worked, linking arm (16) is turned to the position of its axis by the centre of gyration of conveyer, the torsion that linking arm (16) is subjected to is less, easy damaged linking arm (16) not, the stability the during work of raising equipment.
