Detailed Description

The present invention will be described in detail below, but the scope of the present invention is not limited to the following embodiments.

The utility model provides a semi-automatic printer of hot rolling rail on-line longitudinal tracking, is including printing frame 9, location cradle 6, reset spring 8, travelling car 7, propulsion spring 16, cam 15, fixed rail, travelling car 7 is on fixed rail 11, and the travelling car 7 rear end is equipped with propulsion spring 16, it articulates on travelling car 7 to print frame 9, there is steel character head 2 print frame 9's front end, it is equipped with guide pulley 13 to print the rear side of last pin joint of frame 9, guide pulley 13 can roll along the cooperation of cam 15 outer arc, cam 15 is independently fixed, reset spring 8 is in the front side of the bottom pin joint of printing frame 9, the middle part of location cradle 6 is articulated with travelling car 7, the front end of location cradle 6 has location contact 5, the rear end of location cradle 6 can be pushed down by printing frame 9.

Be provided with spring 1 between steel word head 2 and the printing frame 9, the rear side of printing the frame pin joint is fixed with counter weight 14, the bottom of printing frame pin joint rear side is equipped with the arch.

The tail part of the printing frame 9 is provided with a handle 17.

The positioning contact 5 is L-shaped, and the weight of the front part of the hinge point of the positioning cradle is greater than the weight of the rear part of the hinge point.

The printer is arranged on one side of the running roller table 4 of the hot-rolled steel rail 2.

The movable trolley 7 can move back and forth on the fixed guide rail 11, the forward power comes from the propelling spring 16, the backward automatic reset force comes from the rebound force of the reset spring 8 and the inertia force of the counterweight 14, and thus the semi-automatic printing is completed.

The printing frame 9 is hinged with the movable trolley 7 through a printing frame hinge shaft 10, the printing frame 9 rotates by taking the printing frame hinge shaft 10 as a center, and the guide wheel 13 rotates by taking the printing frame hinge shaft 10 as a center and can roll along the outer arc of the cam 15. The cam 15 is independently fixed to the frame.

The lower part of the printing frame 9 is provided with a positioning cradle 6, the middle part of the positioning cradle 6 is hinged on the movable trolley 7 through a positioning cradle hinged shaft 12, and the longitudinal tracking of the bottom plate of the hot-rolled steel rail 3 can be realized through the combined motion of the movable trolley 7 and the positioning cradle 6 and the positioning contact 5 at the front part of the positioning cradle 6. The weight of the front part of the articulated shaft 12 of the positioning cradle is larger than that of the rear part of the articulated shaft 12 of the positioning cradle, when the rear part of the printing frame 9 falls, the rear part of the positioning cradle 6 is pressed down by the bulge at the bottom of the rear side of the printing frame 9, and the front end of the positioning cradle 6 is lifted up.

When the hot-rolled steel rail 3 runs to a hot sawing sizing position and stops on the running roller table 4, a handle 17 of a printing frame 9 is manually lifted up at a proper initial speed and force, a moving trolley 7 automatically moves forward under the action of a pushing spring 16, a bulge at the rear part of the printing frame 9 leaves the tail end of a positioning cradle 6, the front end of the positioning cradle 6 rotates around a positioning cradle hinge shaft 12 under the action of gravity, a front end positioning contact 5 moves downwards and moves forwards along with the moving trolley 7 to track the bottom plate of the hot-rolled steel rail 3, when the positioning contact 5 contacts the bottom plate of the hot-rolled steel rail 3, the moving trolley 7 stops, the printing frame 9 continuously and rapidly rotates around a printing frame hinge shaft 10 under the action of inertia, a steel character head 2 at the front end of the printing frame 9 clearly marks the waist part of the hot-rolled steel rail 3 through lever force, and the printing is finished, at the moment, the printing frame 9 compresses a return spring 8 on the moving trolley 7, under the action of the elastic force of the return spring 8, the printing frame 9 is jacked up and rotates reversely, when the printing frame 9 falls on the cam 15 under the action of the balance weight 14 and stops stably, the bulge at the rear part of the printing frame 9 is pressed at the rear part of the positioning rocking frame 6, the positioning rocking frame 6 rotates, the positioning contact 5 is lifted, and at the moment, the movable trolley 7 is reset to finish one-time printing operation.
