Hoisting beam suitable for water conservancy project gate

Abstract

The invention discloses a hoisting beam suitable for a water conservancy project gate. The hoisting beam comprises a hoisting beam body connected with a crane. A first mounting seat used for mounting of a hoisting hook and a second mounting seat connected with a hoisted object and used for mounting of a hoisting shaft are arranged on the hoisting beam body. The hoisting hook can be arranged on the hoisting shaft in an unhooking manner. A linkage rod is arranged on the first mounting seat. The top end of the linkage rod is connected with a lock tongue. A lock tooth at the top of the hoisting hook is connected to the lock tongue in an abutting manner. An ejector rod is arranged on the second mounting seat. The linkage rod can be connected to the ejector rod in an abutting manner, so that the ejector rod drives the lock tongue to be opened. The hoisting hook is hooked to the hoisting shaft. According to the hoisting beam, the hoisting hook can be stably locked at the opening position through the lock tongue and the lock tooth, the linkage rod is used for controlling action of the lock tongue, and it is guaranteed that the hoisting hook is in place accurately; guide columns and guide rails are utilized for driving the hoisting hook to rotate, and the hoisting hook is opened again to the locking position; and the structure is simple, and automatic hooking and unhooking can be achieved only through a self mechanical mechanism.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering equipment, in particular to a hanging beam suitable for gates of water conservancy projects. Background technique [0002] When water conservancy projects use mobile cranes to open and close multiple gates or trash racks, it is usually necessary to lift the gates by means of lifting beams. The unhooking and unhooking actions of the hanging beam are usually carried out underwater or in a deep gate well, and the unhooking and hooking actions are generally invisible, so the reliability of the unhooking and hooking actions of the hanging beam is very important. [0003] At present, the existing hanging beams still have the problems of low reliability such as unclear force on the hanging point, complex structure, excessive driving force and high self-weight of the hanging beam. Contents of the invention [0004] The purpose of the present invention is to provide a suspension be...
