Technical field
The utility model relates to a kind of high capacity waggon brake-shoe supporting bracket and repairs demo plant.
Background technology
The brake-shoe supporting bracket is the vitals of high capacity waggon braking system, because frequency of utilization height, the corrosion of hoof support dowel hole is supported in braking, wearing and tearing cause brake-shoe pin-and-hole aperture to lose circle, the brake camshaft journal wear, cause brake strip and brake drum decentraction, damping force descends and brake reaction time prolongs, and has a strong impact on car brakeing usefulness, influences vehicle driving safety then.As shown in Figure 1, the brake-shoe supporting bracket comprises two blocks of side plates 2 of rack body 1 and a side space protrusion, rack body 1 center has and rack body 1 is installed on the pilot hole 11 of drive axle and bottom surface and driving axle housing compresses, rack body 1 is interval with some installation screws 12 along pilot hole 11 circumferencial directions, two blocks of side plates 2 are provided with brake-shoe pin-and-hole 21, and rack body 1 has the mounting hole 13 that is inserted in the brake camshaft oscillating bearing at the opposite side of two blocks of side plates 2.
Repairing the brake-shoe supporting bracket is the conventional overhauling project of Mechanical Help industry, generally takes reorientating punching after the built-up welding on the brake-shoe pin-and-hole of wearing and tearing, thereby recovers its original physical dimension, guarantees original and matching relationship brake-shoe.But in built-up welding and punching positioning operation, be difficult to guarantee the hole locating accuracy, make the brake-shoe pin-and-hole location of reparation with original location deviation take place, do not reach the purpose of shape and functional rehabilitation fully.Brake-shoe supporting bracket after repairing produces mismachining tolerance and produces when respectively locating benchmark lack of standardization, can't in time find deviations, checking repairing quality difficulty is very big, if adopt the method validation of service testing, then seriously reduce the car inspection and repair efficiency of operation, increased the labour intensity of upkeep operation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high capacity waggon brake-shoe supporting bracket and repairs demo plant, utilize the checking after this device can conveniently be implemented the reparation of brake-shoe supporting bracket, the repairing quality of efficient check brake-shoe supporting bracket, avoid the deviations of brake-shoe supporting bracket, thereby guaranteed car brakeing usefulness.
For solving the problems of the technologies described above, the utility model high capacity waggon brake-shoe supporting bracket is repaired demo plant and is comprised disc-shaped base, circular sleeve, two first cylinders and four second cylinders, described circular sleeve is vertical at described disc-shaped base center, described two first cylinders are vertical at described disc-shaped base one side at interval, described four second cylinders are vertical on the described disc-shaped base at interval and are positioned at outside the described circular sleeve along described disc-shaped base circumferencial direction, described two first cylinders and four positions of second cylinder on described disc-shaped base and brake-shoe pin-and-hole and the location matches of some installation screws on rack body of brake-shoe supporting bracket, the pilot hole internal diameter coupling of the external diameter of described circular sleeve and rack body, the brake-shoe pin-and-hole internal diameter coupling of the external diameter of described two first cylinders and rack body, some installation screw internal diameter couplings of the external diameter of described four second cylinders and rack body.
Further, above-mentioned disc-shaped base along the circumferential direction is interval with some through holes.
Because the utility model high capacity waggon brake-shoe supporting bracket is repaired demo plant and has been adopted technique scheme, be that this device comprises disc-shaped base, circular sleeve, two first cylinders and four second cylinders, circular sleeve is vertical at the disc-shaped base center, two first cylinders are vertical at disc-shaped base one side at interval, four second cylinders are vertical on the disc-shaped base at interval and are positioned at outside the circular sleeve along the disc-shaped base circumferencial direction, two first cylinders and four second cylinders are in brake-shoe pin-and-hole and the location matches of some installation screws on rack body of the position on the disc-shaped base and brake-shoe supporting bracket, the pilot hole internal diameter coupling of the external diameter of circular sleeve and rack body, the brake-shoe pin-and-hole internal diameter coupling of the external diameter of two first cylinders and rack body, some installation screw internal diameter couplings of the external diameter of four second cylinders and rack body.This device can conveniently be implemented the checking after the brake-shoe supporting bracket is repaired, and efficiently checks the repairing quality of brake-shoe supporting bracket, has avoided the deviations of brake-shoe supporting bracket, thereby has guaranteed car brakeing usefulness.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of high capacity waggon brake-shoe supporting bracket;
Fig. 2 is the structural representation that the utility model high capacity waggon brake-shoe supporting bracket is repaired demo plant;
Fig. 3 is for adopting the synoptic diagram of this device checking brake-shoe supporting bracket.
Embodiment
As shown in Figure 2, the utility model high capacity waggon brake-shoe supporting bracket is repaired demo plant and is comprised disc-shaped base 3, circular sleeve 4, two first cylinders 5 and four second cylinders 6, described circular sleeve 4 is vertical at described disc-shaped base 3 centers, described two first cylinders 5 are vertical at described disc-shaped base 3 one sides at interval, described four second cylinders 6 are vertical on the described disc-shaped base 3 at interval and are positioned at outside the described circular sleeve 4 along described disc-shaped base 3 circumferencial directions, described two first cylinders 5 and four positions of second cylinder 6 on described disc-shaped base 3 and brake-shoe pin-and-hole and the location matches of some installation screws on rack body of brake-shoe supporting bracket, the pilot hole internal diameter coupling of the external diameter of described circular sleeve 4 and rack body, the brake-shoe pin-and-hole internal diameter coupling of the external diameter of described two first cylinders 5 and rack body, some installation screw internal diameter couplings of the external diameter of described four second cylinders 6 and rack body.
