Abstract

The embodiment of the invention provides a connecting vice jib and an engineering machinery, and relates to the technical field of engineering machinery. The connecting vice jib comprises a mast, a connecting arm, an extra arm and a pull plate, wherein one end of the mast is connected with one end of the connecting arm; one end of the pull plate is connected with one end, far away from the connecting arm, of the mast; the other end of the pull plate is connected with one end, far away from the mast, of the connecting arm; one end of the extra arm is connected with one end, far away from the mast, of the connecting arm; the other end of the extra arm is used for installing a lifting tackle; and the extra arm and the connecting arm are arranged to form an included angle. According to the connecting vice jib and the engineering machinery provided by the embodiment of the invention, the extra arm and the connecting arm are connected and are arranged to form the included angle, the extra arm is connected with the connecting arm so as to stretch out of the connecting arm in a suspension way, the extra arm and the connecting arm form a fixed included angle, and when the lifting tackle arranged on the extra arm lifts cargoes during work, the working radius is extended in the cargo lifting process since the extra arm and the connecting arm are arranged to form the included angle, so that the cargoes cannot collide the connecting arm, and the working stability of the connecting vice jib is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular, to a connecting auxiliary arm and construction machinery. Background technique [0002] The traditional fixed jib is composed of four parts. The fixed jib mast is used for connecting the pull plate and guiding the wire rope. The pull plate is used to connect the fixed jib mast and the fixed jib. Fix the upper joint of the jib for the installation of the lifting pulley. The lower section of the fixed jib is used to connect the main arm and install the fixed jib mast. When the crawler crane uses the fixed jib working condition for hoisting, the whole set of fixed jib is connected to the main arm. At the same time, the working condition of the fixed jib is also used for wind power conditions. However, the current fixed jib is limited by the operating radius and cannot meet all wind power conditions. Contents of the invention [0003] The purpose of the present inv...
