Secondary springboard automatic turnover mechanism provided with latching device

Abstract

The invention discloses a secondary springboard automatic turnover mechanism provided with a latching device. The secondary springboard automatic turnover mechanism provided with the latching device can reliably achieve automatic turnover of large and small springboards and turnover latching of a large springboard. The turnover mechanism comprises a large springboard turnover mechanism, a large springboard turnover mechanism latching device and a small springboard turnover mechanism. In the turnover and unfolding process, firstly a small springboard automatically turns over to be in place through the small springboard turnover mechanism, and then unfolding and turnover of the large springboard are achieved through the large springboard turnover mechanism when the latching device is in the unlocking state; and when the large springboard turns over for a specific angle and needs to be fixed, the turnover oil cylinder movement is stopped, the latching device is manipulated to be in the locking state, and thus locking-up and fixing of the large springboard are achieved.

Description

technical field [0001] The invention relates to an automatic turning mechanism, in particular to a two-stage turning mechanism with a locking device. Background technique [0002] The two sides of the crawler self-propelled pontoon bridge are usually provided with a shore springboard, usually the springboard is a second-level springboard, including the first-level springboard (hereinafter referred to as the large springboard) and the second-level springboard (hereinafter referred to as the small springboard), wherein one end of the large springboard is connected to the The end of the crawler self-propelled pontoon box is hinged, and the other end is hinged with the small springboard. The large springboard can be turned over from the crawler self-propelled pontoon box to the specified position through the large springboard turning mechanism (or the large springboard can be withdrawn to the specified position on the crawler self-propelled pontoon box); the small springboard ca...

AI Technical Summary

Problems solved by technology

[0003] During the operation, it is often necessary to flip the large springboard at a certain angle and fix it before performing other operations. At present, the large springboard is usually turned over using a hydraulic flipping system, and the flipping lock is realized by the internal valve parts of the hydraulic system. Although it has a locking function, it is reliable. The safety is not high, and it is easy to cause the lock failure of the large springboard to accidentally turn over and cause damage to personnel and equipment

In addition, the small springboard adopts the manual flipping operation mode, which has a low degree of control and low efficiency in the operation process.
