Embodiment Construction

[0015] The working machine shown in the figures is designed as a concrete pump with a stationary frame 10 . The carrier 10 forms a support column which has at its upper end a substructure 14 with a bearing seat 35 for a swivel head 32 rotatable about a vertical swivel axis 30 . Arranged on the swivel head 32 are booms 16 , 116 each configured as an arm set 34 and a ballast carrier 134 pointing towards the opposite side of the carrying column. The arm set 34 has a plurality of lever arms 1 , 2 , 3 , 4 which are pivotable relative to each other in pairs and which carry the concrete conveying line 22 . especially as from figure 1 and 4 It can be seen that the boom 16 is pivotably supported about a horizontal pivot axis in the assembled state by means of the first lever arm 1 of the arm set 34 on the bearing point 36 of the swivel head 32 . In order to be able to pivot the boom 16 relative to the swivel head 32 , a hydraulic cylinder-piston unit 40 is also provided as a double-...

Abstract

The invention relates to a working device with a base (10) designed as a stationary support column, a motor-driven rotary head (32) and a stack of arms (34) consisting of several mast arms (1, 2, 3, 4) which can be moved with respect to each other in pairs, by means of articulated or sliding joints, supporting a concrete transport line. Said stack of arms (34) is articulated on the rotary head (32) about a horizontal rotational axis (30) by means of a first mast arm (1). The working device also comprises a control mechanism (90) which can be actuated by a control element or a radio path and which is arranged in a control box (92), and a hydraulic assembly (84) comprising an oil tank (86) and a motor-driven hydraulic pump (88) for controlling working groups for moving the rotary head and mast arm. A working platform (78) fixed with respect to the base is arranged in the region of the bearing block (35) for emergency operations. In order to ensure that the components required for actuating the stack of arms (34) are not in the way of the engine in the event of an emergency operation, the control box (92) with the control mechanism (90) and the hydraulic assembly (84) with the oil tank (86) and hydraulic pump (88) are arranged on the rotary head (32) above the bearing block (35).

Description

technical field [0001] The invention relates to a working device comprising: a frame, preferably configured as a stationary support column; a motor-driven swivel head, which is arranged rotatably about a vertical axis of rotation on a support fixed to the frame On the seat; the arm group, the arm group includes a plurality of lever arms that are movable relative to each other on the hinge joint or sliding joint, carrying the concrete delivery pipeline, and the arm group surrounds the horizontal with its first lever arm The axis of rotation of the rotary head is hinged on the rotary head; the control mechanism arranged in the switch cabinet and the hydraulic structural assembly for controlling the drive device for the movement of the rotary head and the movement of the lever arm can be manipulated optionally via a control device or a radio line, The hydraulic structural assembly has an oil tank and a hydraulic pump driven by a motor; and a workbench fixedly arranged with a brac...
