A Selection Mechanism for Connecting Rod Push-Pull Reversing

Abstract

The invention discloses a selection mechanism for connecting rod sliding reversing. The selection mechanism comprises a driving rod, a first connecting rod, a second connecting rod, a third connecting rod, a driven rod and a steering mechanism, wherein the driving rod is simultaneously hinged to the first connecting rod and the second connecting rod; the middle of the first connecting rod is hinged to a fixed bracket, and the other end of the first connecting rod is hinged to the third connecting rod; the other end of the third connecting rod and the other end of the second connecting rod are crossed and are simultaneously connected with the steering mechanism; the steering mechanism comprises a main node, a first welding body and a second welding body are arranged on the two sides of the main node, the outer sides of the first welding body and the second welding body are respectively connected with a first clutch rotating disc and a second clutch rotating disc, a first through hole for the third connecting rod to pass through is formed in the first clutch rotating disc, and a second through hole for the second connecting rod to pass through is formed in the second clutch rotating disc; shaft locking devices are respectively arranged in the first through hole and the second through hole. The selection mechanism has the benefits that the reversing can be realized by the rods, the operation is simple and convenient, and the selection mechanism can be used on a device of which a rod is required for reversing.

Description

technical field [0001] The invention relates to a selection mechanism, in particular to a push-pull reversing selection mechanism with controllable connecting rods. Background technique [0002] Due to the energy crisis, countries all over the world are vigorously promoting the policy of energy saving and emission reduction, especially in the field of machinery. At present, construction machinery mainly uses hydraulic pressure as the power component, but for the existing hydraulic device, it is difficult to greatly improve its energy saving and emission reduction effect. The selection mechanism of the push-pull reversing of the connecting rod is transmitted by the rod, which has high transmission efficiency, and the motor can be directly used as the power source. This kind of mechanical equipment has obvious energy-saving effect and does not have any emissions. However, there are also problems such as multiple dynamic sources, multiple branch chains, and complex operations....
