Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the invention provides a kind of for the jacking system of railway wheel to running-in test, described jacking system be used for rolling stock wheel to 30 decline or lifting, described rolling stock wheel has the wheel of evagination to side 31 to 30; Described jacking system comprises supporting mechanism and lifting mechanism, has coupling end 15 below described supporting mechanism, and described supporting mechanism is fixedly connected with lifting mechanism by coupling end 15; Described supporting mechanism comprises work abutment body 10, described work abutment body 10 bilateral symmetry is provided with the outer bracket rail 13 of " L " tee section, described outer bracket rail 13 is horizontally arranged with two blocks 14, described outer bracket rail 13 and two blocks 14 are formed to be fixed the support of the right side 31 of rolling stock wheel.
Technique scheme by the supporting mechanism with outer bracket rail 13 to rolling stock wheel to 30 side 31 support; retrain fixing side 31 by two blocks 14 simultaneously; prevent it from rolling on outer bracket rail 13; during use; declined by lifting mechanism; rolling stock wheel is slowly reduced in test facility 30; after having tested; promoted by lifting mechanism; by rolling stock wheel to 30 slowly promote and after being separated with experimental facilities; carry out again rolling stock wheel to 30 hang operation, 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 laterally slided on outer bracket rail 13 to the side 31 preventing rolling stock wheel to 30.
Further, described work abutment body 10 both sides have " U " shape conditioning box 11, linear guides 16 is vertically provided with in described conditioning box 11, this preferred version adopts conditioning box 11 structure can slided along linear guides 16, and decline or the enhancing action of constraint lifting mechanism are carried out along the track alignment of linear guides 16 all the time.
Further, described rolling stock wheel has gear case 32 on 30, the work abutment body 10 of described supporting mechanism is arranged the extension platform 12 of support teeth roller box 32, the effect of this preferred version be increase to rolling stock wheel to 30 the support of gear case 32, thus the stability of locomotive car wheel-set 30 when guaranteeing that equipment runs.
In the above-described embodiments, coupling end 15 number below described supporting mechanism is two, described coupling end 15 is mutually corresponding with outer bracket rail 13 in the vertical direction, the program guarantee rolling stock wheel is declined to 30 or lifting operation time, jacking system effectively can support the center of gravity region of 30 each wheels rolling stock wheel all the time.
Further, described lifting mechanism comprises the elevator 21 be arranged on below coupling end 15, and described elevator 21 side is provided with motor 22, and described elevator 21 is connected by transmission shaft 23 with between motor 22; Further, lifting seat 20 is provided with below described elevator 21; Further, described motor 22 can adopt turbine screw lift, and described motor 22 can adopt miniature balancing point reducing motor, and above-mentioned three schemes specialize the structure of lifting mechanism.
Fig. 4, Fig. 5 are the corresponding construction schematic diagrams that jacking system of the present invention is applied in loading running-in experimental engine, wherein, lifting seat 20 is fixedly connected with equipment base 40, the friction wheel 41 of this jacking system and loading running-in experimental engine is in the state of dodging, avoid jacking system support locomotive car wheel-set 30 carry out declining or lifting operation time interfere with friction wheel 41.During use, by outer bracket rail 13 and block 14 formed to rolling stock wheel to 30 the constraint carried out of side 31 support, by elevator 21, rolling stock wheel is reduced downwards 30, until rolling stock wheel to 30 tread 33 touch friction wheel 41, now elevator 21 continues to drive this jacking system to move downward, until without interfering between jacking system and friction wheel 41, after test completes, jacking system is again by promoting, rolling stock wheel is separated with friction wheel 41 30, after it rises to certain altitude, directly rolling stock wheel is hung loading running-in experimental engine to 30.
