Embodiment
Shown in Fig. 1-2, hydraulic motor location locking mechanism of the invention includes back guide 14 and front guide 12, is led at two
Tensioning oil cylinder 3 is set between plate, and the chain joint 7 being connected with tensioning oil cylinder rod end, the chain joint 7 can be moved in the axial direction.In chain
It is tensioning rod aperture to have mesopore on joint.Front guide top is to have geared sleeve 6 in gear-box 15, gear-box, the rear portion of the geared sleeve 6
Connect with the end face of chain joint 7, the central through hole of geared sleeve 6 is the tensioning rod aperture concentric with the mesopore of chain joint 7, the tensioning of chain joint
Rod aperture arrival end has turning slot 17, there is two limit screws 11 for being in 180 degree setting, geared sleeve 6 on turning slot circumference
Rear end face circumference on have two boss 10 that Corresponding matching is followed closely with stop spiral shell 11 for being mutually 180 degree setting, while geared sleeve 6
Back end circumference side matches for chamfering shape panoramic table with turning slot 17.The front end face tension rod arrival end of geared sleeve 6 is formed with two mutually
There is locking screw on the locking groove 9 set into 180 degree, the body of rod of tension rod 2, an abnormity nut 1 be socketed on the locking screw,
The cylindrical of the abnormity nut is provided with two external tooth form boss 8 and the Corresponding matching of locking groove 9.It is provided with geared sleeve excircle
Locking gear 16.Shown in figure, geared sleeve 6 is placed in the mounting hole of front guide 13, and hydraulic motor is fixed with geared sleeve top
