Abstract
The utility model discloses a stone sweeper mechanism and aims to solve the problem that the existing stone weeper is easy to crack due to bearing of shearing force during operation of a locomotive. The stone sweeper mechanism comprises a stone sweeper support seat which is arranged on the stone sweeper mounting seat, and a structure which is used for limiting the stone sweeper support seat to move relative to the stone sweeper mounting seat is arranged on a mounting surface of the stone sweeper support seat. The stone sweeper mechanism has the advantages of reducing contact area between mounting surfaces and a gap between the mounting surface and the contact area, and avoiding crack of mounting bolts due to the bearing of shearing force. After the length of a support pipe which is arranged in a stone sweeper support is contracted, self weight of the stone sweeper is greatly reduced, and meanwhile, shortening of a lever arm enables force status of the stone sweeper mechanism to be greatly improved.
Description
Technical field
The utility model relates to rolling stock structure design field, is applied on the similar vehicles bogie trucks such as locomotive and city rail.
Background technology
Sweeping the stone implement support and be contained on locomotive or the city rail vehicle, mainly is in order to know the obstacle on the Vehicle Driving Cycle rail level.The simple and easy stone implement of sweeping of a kind of Type B metro bogie is disclosed such as Chinese patent CN201020197817.X, it provides interface in a Che Yiwei truck frame end for the simple and easy stone implement of sweeping, be bolted to the framework end by four, and then provide interface simple and easy sweeping on the stone implement support for equipment such as dry type rim lubricating devices.
But, present sweeps stone implement when locomotive uses, the situation of the fracture of stone implement support or bolt failure often appears sweeping, tracing it to its cause mainly is because the currently used weight ratio of stone implement structure of sweeping own is heavier, and after on being installed in framework, larger gap is arranged between the attachment face, in operational process, the hold-down bolt of sweeping the stone implement support is just easily loosening, and therefore bolt is subject to shearing force and ruptures, and the whole stone implement of sweeping easily ruptures at weld after also being given a shock.
The utility model content
In the locomotive operation process, be subjected to the easily deficiency of fracture of shearing force in order to overcome the existing stone implement of sweeping, the utility model aims to provide a kind of stone implement mechanism of sweeping, this is swept stone implement mechanism and is mainly used on locomotive and the city rail vehicle bogie truck, can effectively avoid hold-down bolt to bear shearing force and damages.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of stone implement mechanism of sweeping comprises being contained in to sweep and sweeps the stone implement bearing on the stone implement mount pad, and its constructional feature is, the described attachment face of sweeping the stone implement bearing is provided with restriction and sweeps the stone implement bearing relative to the structure of sweeping the stone implement mount pad and moving.
Thus, sweep the shearing force that the hold-down bolt on the stone implement bearing bears very little, even do not bear shearing force, avoided hold-down bolt in the locomotive operation process, to damage because bearing shearing force, be contained in to sweep on the stone implement bearing and be used for sweeping sweeping slabstone and just can sweeping safely and reliably stone of stone.
Below be the technical scheme of further improvement of the utility model:
Further, the version of commonly using as a comparison, it is groove or projection relative to sweeping the structure that the stone implement mount pad moves that the stone implement bearing is swept in described restriction, can certainly be other structures, such as hole or post, sweep the stone implement bearing and move relative to sweeping the stone implement mount pad as long as can realize restriction, avoid sweeping hold-down bolt on the stone implement bearing and do not bear or bear less shearing force and get final product.
Sweep stone implement bearing attachment face upper groove or projection is corresponding is that the described attachment face of sweeping the stone implement mount pad is provided with projection or the groove that and groove or projection matches with being located at.
As a kind of preferred version, described groove is cross bath, sweeps that correspondence is provided with projection on the attachment face of stone implement mount pad, sweeps the stone implement bearing and has limited in all directions the movement of sweeping the stone implement bearing thereby can limit, and has avoided bolt to bear shearing force.
Compared with prior art, the beneficial effects of the utility model are: of the present utility modelly sweep the gap that the stone implement structure has reduced the contact surface between the attachment face and existed between the two, avoided hold-down bolt because ruptured by shearing force.Sweep that the weight of self has reduced much after the contraction in length of support tube in the stone implement support, the while shortening of the arm of force improves the force-bearing situation of this structure greatly.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Description of drawings
Fig. 1 is the structure principle chart of a kind of embodiment of the utility model.
In the drawings
The 1-steel plate; The 2-support tube; 3-sweeps the stone implement bearing; 4-groove or projection; The 5-bolt hole.
The specific embodiment
A kind of stone implement mechanism of sweeping, as shown in Figure 1, comprise being contained in to sweep and sweep stone implement bearing 3 on the stone implement mount pad, be contained in to sweep on the stone implement 3 and be equipped be used to the steel plate 1 of sweeping stone by support tube 2, the described attachment face of sweeping stone implement bearing 3 is provided with cross groove 4, correspondingly, the described attachment face of sweeping the stone implement mount pad is provided with the criss-cross projection that matches with cross groove 4, sweeps stone implement bearing 3 for restriction and moves relative to sweeping the stone implement mount pad.
The present embodiment improves the stone implement support of sweeping commonly used on locomotive and the city rail vehicle: on the mounting plane of sweeping the stone implement bearing, process the groove of " a ten " font.Framework is swept on the stone implement mount pad boss that increases " a ten " font, and sweeps stone implement bearing attachment face and cooperates.So not only limited the motion of the horizontal direction of sweeping stone implement, and the gap that has reduced the contact surface between the attachment face and existed between the two, pass the hold-down bolt of sweeping stone implement bearing 3 upper bolt holes 5 and just can avoid because ruptured by shearing force.
The content that above-described embodiment is illustrated should be understood to these embodiment and only is used for being illustrated more clearly in the utility model, and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Claims (4)
1. sweep stone implement mechanism for one kind, comprise being contained in to sweep and sweep stone implement bearing (3) on the stone implement mount pad, it is characterized in that, the described attachment face of sweeping stone implement bearing (3) is provided with restriction and sweeps stone implement bearing (3) relative to the structure of sweeping the stone implement mount pad and moving.
2. the stone implement mechanism of sweeping according to claim 1 is characterized in that, it is groove or projection (4) relative to sweeping the structure that the stone implement mount pad moves that stone implement bearing (3) is swept in described restriction.
