Abstract
The utility model discloses a kind of brake pull-rod stiffening device, relate to the driving mechanism technical field imposing mechanical external force to operate to switch.It comprises the insulation body of internal diameter and brake pull-rod major diameter fit, and insulation body is enclosed within the outside of brake pull-rod and tightens by bolt and brake pull-rod; Insulation body is made up of two and half bodys; The first side of two and half bodys is hinged in the longitudinal direction; The second side of two and half bodys is evenly distributed with back-off and draw-in groove in the longitudinal direction respectively; The draw-in groove snap-fit engagement that back-off is corresponding with its position.The beneficial effects of the utility model are: on the basis of original brake pull-rod, can be arranged on brake pull-rod fast, add brake pull-rod flexural strength.
Description
Technical field
The utility model relates to the driving mechanism technical field imposing mechanical external force to operate to switch.
Background technology
The brake pull-rod of outdoor 10kV disconnecting link is due to upper and lower distance, and easily cause to bend making not easy to operate in drawing process putting in place in operation, it is commonplace that this phenomenon occurs.If all change the brake pull-rod of thicker specification, workload is large, and the brake pull-rod of replacing will slattern.
At present, the more protection device of the brake pull-rod that also not will not bend not for bending or support force.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provides a kind of brake pull-rod stiffening device, on the basis of original brake pull-rod, can be arranged on brake pull-rod fast, add brake pull-rod flexural strength.
The technical solution adopted in the utility model is: provide a kind of brake pull-rod stiffening device, comprises the insulation body of internal diameter and brake pull-rod major diameter fit, and insulation body is enclosed within the outside of brake pull-rod and tightens by bolt and brake pull-rod; Insulation body is made up of two and half bodys; The first side of two and half bodys is hinged in the longitudinal direction; The second side of two and half bodys is evenly distributed with back-off and draw-in groove in the longitudinal direction respectively; The draw-in groove snap-fit engagement that back-off is corresponding with its position.
Further optimization the technical program, two and half bodys of brake pull-rod stiffening device are made by phenolic resins material.
Further optimization the technical program, two and half bodys of brake pull-rod stiffening device are made by epoxy resin material.
The beneficial effects of the utility model are: 1, convenient installation, Stability Analysis of Structures.Before not installing, the first side of two and half bodys is hinged, and two second sides are in released state, is directly inserted in by brake pull-rod between two and half bodys, then the back-off of two second sides is snapped in draw-in groove; Sliding to prevent from producing between body and brake pull-rod, tighting a bolt.2, phenolic resins material or epoxy resin material all have excellent insulating properties, and the intensity of two kinds of materials and toughness are relatively good in ambroin.
Accompanying drawing explanation
Fig. 1 is using state schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model.
In figure, 1, brake pull-rod; 2, insulate body; 3, bolt; 4, half body; 5, first side; 6, second side; 7, back-off; 8, draw-in groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, brake pull-rod stiffening device, comprises the insulation body 2 of internal diameter and brake pull-rod 1 major diameter fit, and insulation body 2 is enclosed within the outside of brake pull-rod 1 and tightens by bolt 3 and brake pull-rod 1; Insulation body 2 is made up of two and half bodys 4; The first side 5 of two and half bodys 4 is hinged in the longitudinal direction; The second side 6 of two and half bodys 4 is evenly distributed with back-off 7 and draw-in groove 8 in the longitudinal direction respectively; Draw-in groove 8 snap-fit engagement that back-off 7 is corresponding with its position; Two and half bodys 4 are made by phenolic resins material; Two and half bodys 4 are made by epoxy resin material.
As shown in Figure 2, the utility model is before being installed on brake pull-rod 1, and be in the back-off 7 of open mode-to be namely separated with draw-in groove 8, two and half bodys 4 are opened at an angle, and the end of bolt 3 is basic fair with half body 4 inwall at its place.
During installation, is first fitted in the side of a hemizonid 4 with brake pull-rod 1, then rotate another hemizonid 4, make back-off 7 insert draw-in groove 8(and be pressed into all corresponding with it draw-in groove 8 firm plug of all back-offs 7).
The internal diameter of the insulation body 2 of the utility model indication and the major diameter fit of brake pull-rod 1 refer to: the bigger external diameter (gap remains to 0.2CM-0.5CM) with brake pull-rod 1 of the internal diameter of the body 2 that insulate, reserves surplus when such object is and is separated with draw-in groove 8 to back-off 7.
