Rihtovschik 12B GR (GR 12) produced by different factories. It is shown in Fig. This is rihtovschik mentioned parts. Mounted on the ballast support 13 hinge 14 is connected to the piston (rod) 2, a spring-loaded return spring 1 relative to the cylinder 3. In the area of the hinge 14 with a support 13 fastened handle 15. The piston is made hollow, at the end of his set seal oil resistant rubber sleeve. On the opposite side is placed a felt seal.
Cylinder with the right end is screwed into the cup 20. By the glass hard welded comb 6 with three projections. This one of its projections (depending on the level of ballast in shpalnom case) is supplied under the sole rihtuemogo rail. C the opposite side of the hinge pillar 14 (hinge 16) is connected to the yoke 7, which is (a special hinge 17) is connected with a rod (shoe) 9. Coulter other end (hinge 77) is connected to the comb pusher. In the area of hinge 16 and 7 established mutual rotation limiters 12 levers that prevent them from rotation of the hydraulic plunger down. The drive is a manual rihtovschika dvuhplunzherny hydraulic pump 4 and 5 (a symmetric slider-type rocker arm with the connecting rods and pistons, sliders). Rocker arm shake a removable cat-8 (the handle is used for planning and ballast in the workplace).
To return to the starting position rihtovschika (Discharge pressure in the cylinder) in the case – an oil reservoir 4 pumps – installed ball valve with a rotating handle 10. In the initial position rihtovschik return under the influence of the return spring force and pressure on cylinder rihtuemoy track panel. On the lid of the tank above the oil filler cap is installed, the breather 75. In addition to the handle 75 is provided with a handle rihtovschik 79, fastened to the top of the pump. With these pens rihtovschik transferred and installed in the box for shpalny so that the front part of the support with a narrow shoe sole located at the rail. To increase stability when working rihtovschika on loose gravel on the shovel put a removable liner. However, one of the protrusions abut the comb in the sole rail. Activating the pump swinging arm, oil supplied to the cylinder, and as a result he was nominated along with the hinged shoe 9. He crushes on the beam 7, buried it in the ballast, while posting a path. Relative position of parts of the Richt-schika (beam, the opener, support) depends on the magnitude of the displacement cylinder and the forces of the resistance to the effects of ballast her entire device. Upon reaching the substantive and the corresponding degree of compaction of ballast shifted path.
