Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provide a kind of for railway wheel the lowering or hoisting gear to running-in test, described lowering or hoisting gear for rolling stock wheel to 30 decline or lifting, described rolling stock wheel to 30 wheels with evagination to side 31; Described lowering or hoisting gear comprises supporting mechanism and elevating mechanism, and described supporting mechanism below has link 15, and described supporting mechanism is fixedly connected with elevating mechanism by link 15; Described supporting mechanism comprises work abutment body 10, described work abutment body 10 bilateral symmetry are provided with the outer bracket rail 13 of " L " tee section, on described outer bracket rail 13, be horizontally arranged with two blocks 14, the support that described outer bracket rail 13 and two blocks 14 form the side 31 right to rolling stock wheel is fixed.
Technique scheme supports 30 side 31 rolling stock wheel by the supporting mechanism with outer bracket rail 13; simultaneously by two blocks, the 14 fixing sides 31 of constraint; prevent that it from rolling on outer bracket rail 13; when use; decline by elevating mechanism; rolling stock wheel is slowly reduced in testing equipment 30; after having tested; promote by elevating mechanism; after rolling stock wheel slowly being promoted 30 and separating with experimental facilities; carry out again rolling stock wheel to 30 the operation that hangs, be conducive to the protection to experimental facilities.
Further, the one end away from outer bracket rail 13 on described block 14 upwards extends to form protuberance 14a, and the effect of this protuberance 14a is to preventing that rolling stock wheel from laterally sliding on outer bracket rail 13 to 30 side 31.
Further, described work abutment body 10 both sides have " U " shape conditioning box 11, the interior linear guides 16 that is vertically provided with of described conditioning box 11, this preferred version adopts conditioning box 11 structures that can slide along linear guides 16, and decline or the enhancing action of constraint elevating mechanism are carried out along the orbital direction of linear guides 16 all the time.
Further, described rolling stock wheel has gear-box 32 on 30, the extension platform 12 of support teeth roller box 32 is set on the work abutment body 10 of described supporting mechanism, the effect of this preferred version is to increase the support to 30 gear-box 32 to rolling stock wheel, thereby while guaranteeing equipment operation, rolling stock wheel is to 30 stability.
In the above-described embodiments, link 15 numbers of described supporting mechanism below are two, described link 15 is mutually corresponding with outer bracket rail 13 in the vertical directions, this scheme is guaranteed rolling stock wheel being declined to 30 or when lifting operation, lowering or hoisting gear can effectively support the center of gravity region of 30 each wheels rolling stock wheel all the time.
Further, described elevating mechanism comprises the lift 21 that is arranged on link 15 belows, and described lift 21 1 sides are provided with motor 22, between described lift 21 and motor 22, are connected by power transmission shaft 23; And described lift 21 belows are provided with lifting seat 20; And described motor 22 can adopt turbine screw lift, described motor 22 can adopt miniature balancing point reducing motor, and above-mentioned three schemes are that the structure of elevating mechanism is specialized.
