Pitching arm with operation chamber and material taking machine

Abstract

The invention discloses a pitching arm with an operation chamber and a material taking machine. The pitching arm (1) comprises a first supporting table (3), the operation chamber (2), a fixed supporting beam (8) and a walking stairway (7), wherein a supporting rod (5) and a telescopic cylinder (6) stretch upwards on the first supporting table (3); a bottom plate of the operation chamber (2) is hinged to the supporting rod (5) and the telescopic cylinder (6); the upper end of the walking stairway (7) is hinged to the operation chamber (2); a slide is formed inside the walking stairway (7); the fixed supporting beam (8) is provided with a roller; and the roller slides along the slide during the leveling process of the operation chamber (2). According to the pitching arm, the connection manner of the walking stairway and the fixed supporting beam is designed as that the fixed supporting beam slides on the walking stairway, so that the angle change of the walking stairway during pivotal leveling of the operation chamber can be reduced, the steep degree of the walking stairway is reduced, an operator walks on the walking stairway more conveniently, and the safety is improved.

Description

technical field [0001] The invention relates to the field of reclaimers, in particular to a pitch arm with an operating room and a reclaimer. Background technique [0002] The bucket wheel reclaimer is suitable for loading and unloading transportation of materials in ports, and includes a pitching arm capable of pivoting up and down, and an operating room is installed on the upper side of the pitching arm. During the pitching process of the pitching arm, the operating room at one end of the pitching arm also tilts accordingly. In order to keep the operating room in a horizontal installation state, the operating room is also installed in a pivoting manner, and the operating room is always in a horizontal state through the telescopic drive of the telescopic cylinder. [0003] like figure 1 As shown, the operating room 2 is hinged and supported on the top end of the supporting rod 5 on the first support platform 3 , and the telescopic cylinder 6 on the first supporting platfo...

AI Technical Summary

Problems solved by technology

[0004] When the pitching angle of the pitching arm 1 is very large, such as at the extreme position, the leveling pivot angle of the operating room 2 is also very large in order to maintain the horizontal operation room 2, which causes the overall inclination angle of the walking ladder 7 relative to the horizontal ground to be very large and very steep , it is very dangerous to walk on it
