Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a leopard lion in pit dump truck gear shifting device, its characterized in that: fix the connection fixed head I1 on the gear action bars including one end, the connection fixed head II2 on the gearbox gear valve is fixed to one end, connect fixed head I1 and be connected with steel wire heart yearn 3 between the fixed head II2, the outside cover of 3 outer covers of steel wire heart yearns has outer pipe box 4, 3 tip of steel wire heart yearn are provided with can adjust 3 length's of steel wire heart yearn flexible axle fixed regulation device 5.
As shown in fig. 2, the flexible shaft fixing and adjusting device 5 comprises a barrel-shaped shell 5.1, one end of the barrel-shaped shell 5.1 is provided with a hole, the outer pipe sleeve 4 is fixedly connected with the hole, the steel wire core wire 3 penetrates through the hole and extends into the barrel-shaped shell 5.1, the adjusting bolt 5.2 is arranged on the side wall of the barrel-shaped shell 5.1 in a penetrating manner, and the adjusting bolt 5.2 is fixedly connected with the end part of the steel wire core wire 3 at one section inside the barrel-shaped shell 5.1. By rotating the adjusting bolt 5.2, the length of the steel wire core wire 3 wound on the adjusting bolt 5.2 is adjusted, and then the length of the steel wire core wire 3 is adjusted.
Wherein, connect fixed head I1 and be the shaft-like structure of threaded, with the screw hole threaded connection who sets up on the gear action bars.
