Abstract
The utility model relates to a split type rapid repairing chain ring used for a wagon. The split type rapid repairing chain ring is characterized in that the split type rapid repairing chain ring comprises a pair of arch type semi-rings which are meshed with each other and symmetrically arranged, the two sides of each arch type semi-ring are respectively provided with a connecting table which extends horizontally, a connecting hole is perpendicularly formed in the connecting table on each side of the corresponding arch type semi-ring, the two arch type semi-rings are oppositely arranged and are aligned with the connecting holes on the connecting tables, a bolt penetrates through the aligned connecting holes on one side of one of the arch type semi-rings and on one side of the other arch type semi-ring, and each bolt and the corresponding connecting holes are locked and fastened into a whole through matching of a gasket and a nut. A broken hand braking chain ring can be rapidly and timely connected through the split type rapid repairing chain ring, and therefore the broken hand braking chain ring can be prevented from invading the limit and influencing the running, and the repaired hand braking chain ring can meet the requirement for normal parking braking. The split type rapid repairing chain ring can be widely applied to braking systems of various wagons.
Description
Technical field
The utility model relates to a kind of repairing apparatus, particularly about split type Rapid-Repair chain link for a kind of railway freight-car.
Background technique
Since 20 century 70s, there are great changes in the traffic condition of China railways, progressively formed the enterprise schema that " speed, density, weight " lays equal stress on and networking is transported, and the requirement of freight car braking equipment is also progressively improved along with the development of railway freight.Hand brake device is the braking device that prevents the slippery setting of vehicle when to be vehicle park in field, station.Hand braking chain link is applied in hand brake device, plays the effect of transmitting hand brake force, finds that hand braking chain link exists the phenomenon of fracture in vehicle uses, and after chain link fracture, the sagging intrusion vehicle gauge of hand braking chain, causes safely adverse effect to vehicle driving.The existing hand brake device mode of action, such as: as shown in Figure 1, manual brake 1 is connected on car body 3 by associate member 2, and meanwhile, the hand braking chain link 4 on manual brake 1 is connected with hand brake lever 6 by movable pulley 5.When hand braking, by rotation manual brake 1, hand brake force is delivered on hand brake lever 6 by hand braking chain link 4, final conduction is carried out braking action for braking force.Existing hand braking chain link structure is that a plurality of occluded ellipse shape annulus 7 sockets form (as shown in Figure 2), and oval annulus 7 adopts round steel to bend and forms, and is welded as close-shaped at each oval annulus 7 jointing 8.In vehicle uses, due to the corrosion of oval annulus 7 and the impact of outside destroy, one or more chain links in hand braking chain link 4 are at weld or other weakness and easily rupture, cause the separated of manual brake 1 and hand brake lever 6, this not only can not play hand braking effect, while disconnecting sagging chain link intrusion vehicle gauge, also can have influence on the traffic safety of vehicle.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind ofly can guarantee traffic safety, and can carry out the split type Rapid-Repair chain link for railway freight-car of repairing fast to the hand braking chain link that ruptures.
For achieving the above object, the utility model is taked following technological scheme: split type Rapid-Repair chain link for a kind of railway freight-car, it is characterized in that: it comprises a pair of relative interlock and the arch form semi-ring being symmetrical set, described arch form semi-ring both sides are respectively arranged with the connected unit that a level is stretched out, equal vertical attachment hole that is provided with in connected unit described in each side; Described in two arch form semi-ring be oppositely arranged and the both sides of aliging described in described attachment hole in connected unit, in the described attachment hole of each side alignment, penetrate respectively a bolt, and by packing ring and nut, lock and be fixed as one respectively.
Bottom surface in connected unit described in a side is provided with some double wedges, is provided with the recessed tooth with the mutual interlock of described double wedge in the bottom surface of connected unit described in opposite side; Described in two, arch form semi-ring bottom surface, relatively by described double wedge and the mutual snap-in location of recessed tooth, makes the attachment hole automatic aligning of connected unit described in two.
Described arch form semi-ring is made through machining after adopting round steel forging and stamping again.
The utility model is owing to taking above technological scheme, it has the following advantages: 1, the utility model is due to the Rapid-Repair that adopts split type chain link to carry out hand braking chain link fracture, can in time the chain link of fracture be coupled together fast, therefore avoid the chain link fouling of clearance gauge disconnecting and affect operation, hand braking chain link after repairing can meet normal stopping brake requirement, is also convenient to carry in driving way simultaneously.2, the utility model is because two surface of contact of the arch form semi-ring at split type chain link are provided with the flank of tooth of mutual interlock, by the double wedge of connected unit bottom surface and the mutual interlock of recessed tooth of arch form semi-ring, can strengthen two arch form semi-ring join strengths, the attended operation that simultaneously also contributes to repair chain link.Therefore make to repair connection more efficient and convenient, connect more firm.3, link of the present utility model is owing to adopting arch form structure design, therefore simple in structure, is convenient to processing, can also effectively reduce the expense of repairing chain link.The utility model can be widely used among the hand braking chain link fracture of different kinds of railways lorry repairing.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 3, Figure 4, the utility model comprises a pair of relative interlock and the arch form semi-ring 10 being symmetrical set, arch form semi-ring 10 both sides are respectively arranged with the connected unit 11,12 that a level is stretched out, equal vertical attachment hole 13 that is provided with in each side connected unit 11,12.In the bottom surface of connected unit 11, be provided with some double wedges 14, in the bottom surface of connected unit 12, be provided with the recessed tooth 15 with double wedge 14 mutual interlocks.Two arch form semi-ring 10 bottom surfaces are relatively by double wedge 14 and the mutual snap-in location of recessed tooth 15, and then make attachment hole 13 automatic alignings of two connected units 11,12, in the attachment hole 13 of each side alignment, penetrate respectively a bolt 16, and by packing ring 17 and nut 18, lock and be fixed as one respectively.
In above-described embodiment, arch form semi-ring 10 adopts round steel forging and stamping to make by machining.The double wedge 14 of connected unit 11,12 bottom surfaces of arch form semi-ring 10 and the mutual interlock of recessed tooth 15 can strengthen two arch form semi-ring 10 join strengths, the attended operation while simultaneously also contributing to repair.
