The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment and the principle of work of the linkage that proposes according to the utility model is elaborated.
The linkage that the utility model provided comprises con-rod only.Fork on one end of this con-rod only and the railway truck on the horizontal major axis 13 of operating handle bonded assembly is connected, and the operator in the other end of con-rod only and the two-tube Pneumatic brake systems of railway truck is being connected.Different with con-rod only in the prior art is that the con-rod only in the utility model comprises a plurality of connecting rods, is fastenedly connected each other through the adjustable mode of spacing between each connecting rod, thereby realizes the con-rod only adjustable length.
To operate in the fixed installation space in order being more convenient for, and to make the assembly in this device accessible when needs are changed, can be with interconnecting through removable mode and with the adjustable mode of spacing between each connecting rod., adopted in the present embodiment to comprise to shown in Figure 6 like Fig. 3: first connecting rod 5, first jam nut 6, the assembly that female tubular attaching parts 7, second jam nut 8, second connecting rod 9 be set are realized this technical scheme.Wherein, first connecting rod 5 is provided with outside thread with second connecting rod 9 interconnective ends, and the outside thread on outside thread on the first connecting rod 5 and the second connecting rod 9 is in the opposite direction; The negative thread that tubular attaching parts 7 two ends are provided with in the opposite direction is used for interconnecting and adjust spacing with first connecting rod 5, second connecting rod 9 respectively; The thread end of first connecting rod 5 is connected with the threaded one end of first jam nut 6, tubular attaching parts 7, and is when adjusting to suitable spacing, fastening through first jam nut 6; The thread end of second connecting rod 9 is threaded with the other end of second jam nut 8, tubular attaching parts 7, and is when adjusting to suitable spacing, fastening through second jam nut 8.
Employing is provided with female tubular attaching parts, first jam nut, second jam nut, first connecting rod, second connecting rod and makes up the utility model, can be easy to processing and fabricating, install and connect, and satisfy adjustable length, the requirement of reliable lock.
As shown in Figure 5, preferred for the outer wall construction of tubular attaching parts 7, it is arranged to the structure of rough structure, perhaps be arranged to many ribs structure, so that make tubular attaching parts 7 be easier to rotary mediation.For tubular attaching parts 7, can also the center be set out the opening by outer wall to its axle center part of tubular attaching parts.Such set-up mode also can be more conducive to operating personal the tubular attaching parts is regulated; And can be rotated conciliation to the tubular attaching parts by serviceable tool insertion aperture position; More laborsaving, but also the deadweight that can solve material, cost-cutting, alleviate tubular attaching parts 7.
For the utility model and operator the connection mode between, the fork; Preferably; With the operator between the fork on the horizontal major axis of operating handle bonded assembly on con-rod only and the railway truck, in con-rod only and the two-tube Pneumatic brake systems of railway truck between; All interconnect, can make this device be easy to the dismounting maintenance through removable mode.For example, with an end of con-rod only through round pin, packing ring, spring cotter and operator link to each other, the other end passes through round pin, packing ring, spring cotter link to each other with the major axis upper shift fork.
Before the utility model was installed, the relevant position drilled through the hole on major axis 13 earlier, the fork 15 of the fork 14 of control control cock handgrip, control cut out cock handgrip; After being fixed on the major axis 13 through resilient pegs respectively; The linkage 16 that one cover the utility model provides respectively is installed on two forks again,, handgrip on the control cock, cut out cock handgrip can be positioned at simultaneously opens position or close stance (like Fig. 1, Fig. 2, shown in Figure 7) through operation lorry both sides operating handle 12,17; At this moment; Fastening first jam nut 6, second jam nut 8, whole device gets final product normal operation, and the linkage assembling scheme drawing that the utility model provides is seen Fig. 6, Fig. 8, Fig. 9.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
