Gantry crane stable in use and high in safety performance

Abstract

The invention relates to the technical field of bridge construction equipment, and discloses a gantry crane stable in use and high in safety performance. The gantry crane comprises a gantry beam, andlocating seats are mounted at the top and the bottom of an inner cavity of the gantry beam. The middles of the two locating seats are fixedly connected through locating columns, and the two sides of the bottom of the gantry beam are fixedly connected with connecting plates. The bottoms of the two connecting plates are fixedly connected with stand columns, one ends of the bottoms of the two stand columns penetrate through fixed seats, and limiting plates are mounted at the bottoms of the stand columns. The bottoms of the limiting plates and the bottoms of inner cavities of the fixed seats are fixedly connected, and the joints of the stand columns and the fixed seats are sleeved with sleeve plates. The tops of the stand columns and the tops of the fixed seats are fixedly connected with clamping seats. According to the gantry crane stable in use and high in safety performance, the clamping seats, the limiting plates, the fixed seats, the sleeve plates and rubber pads are arranged to be used in cooperation, the function of supporting and stabilizing the stand columns can be achieved in the use process of the gantry beam, and the stability of the stand columns in the use process is guaranteed.

Description

[0001] This application is a divisional application of a patent with an application date of April 27, 2017, an application number of 201710286589X, and an invention title of "a gantry crane with stable use and high safety performance". technical field [0002] The invention relates to the technical field of bridge construction equipment, in particular to a gantry crane with stable use and high safety performance. Background technique [0003] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles. Th...
