Example 1

As shown in fig. 1 and 2, the guiding device for automatically adjusting pressure provided by the application comprises two pressure adjusting assemblies arranged on two sides of a rail 3, wherein each pressure adjusting assembly comprises a guiding fixing piece and a guiding wheel 2; in this application, the pressure adjusting components are two, are respectively located at two sides of the rail 3, and are symmetrical structures, and the structures are the same, and the following description is specifically performed by only one of the structures.

The guide fixing piece comprises a horizontal support 8, a vertical support 12, a fixing support 11 and a joint support 13, wherein the horizontal support 8 is located above the rail 3 and perpendicular to the extending direction of the rail 3, the vertical supports 12 are arranged at two ends of the horizontal support 8, the vertical supports 12 are parallel to the side face of the rail 3, the fixing support 11 is located on the front side or the rear side of the horizontal support 8, and the fixing support 11 and the vertical supports 12 are staggered.

A joint bracket 13 is arranged between the vertical bracket 12 and the rail 3, the vertical bracket 12 and the joint bracket 13 are plates parallel to the side surface of the rail 3, and a guide wheel 2 capable of sliding along the extending direction of the rail 3 is arranged on one side of the joint bracket 13 close to the rail 3; in the extending direction parallel to the rail 3, one end of the joint bracket 13 is connected with the vertical bracket 12 through an adjusting rod, and the other end is fixedly connected with the fixed bracket 11.

In this application, the guide pulley is close to the upper fishplate bar and the lower fishplate bar of one side setting parallel of rail, is provided with the guiding axle between upper fishplate bar and the lower fishplate bar, and guide pulley 2 sets up in guiding axle 8.

The fixing bracket 11 may be fixed on the front side or the rear side of the horizontal bracket 8, where the front side or the rear side is the front side in the moving direction, i.e., the rear side in the moving direction, with respect to the moving direction of the guide wheel 2 in the rail 3. The fixing bracket 11 fixes one end of the joint bracket 13, and the fixed end of the joint bracket 13 can be a front end or a rear end, and the corresponding end of the joint bracket 13 away from the fixing bracket 11 can move along with the adjusting rod in a direction away from or close to the rail 3.

The fixed support 11 can be fixed on the vertical support 12 in this application, also can fix on the horizontal support 8, because in the pressure adjustment process, fixed support 11, vertical support 12 and horizontal support 8 are all relatively motionless, only one end that keeps away from fixed support 11 in the joint support 13 can be along with adjusting the pole towards the direction of keeping away from or being close to rail 3.

In this application, the fixed support 11 is connected with the joint through the joint sleeve 10, and the joint sleeve 10 exists for the one end that the joint support 13 is connected with the joint sleeve 10 keeps motionless, and the one end of keeping away from the fixed support 11 can rotate along the joint sleeve 10, and the rotatory process is the one end that keeps away from the fixed support 11 in the joint support 13 along with adjusting the pole along with keeping away from or being close to the process that the rail 3 direction removed.

The effect of adjusting the pole in this application is guaranteeing that the pressure between leading wheel 2 and the rail 3 is invariable, and when the pressure between leading wheel 2 and the rail 3 became big, the regulation pole can shorten for keep away from the one end of fixed bolster 11 in the joint support 13 along with adjusting the pole and remove towards the direction of keeping away from the rail 3, and then make the pressure between leading wheel 2 and the rail 3 keep the setting value.
