Abstract
The invention discloses a motor train unit under-car suspension piece bottom plate equipment anti-separating lock, belongs to rail transit vehicles and particularly belongs to the technical field of high speed train bottom plate equipment mounting. The motor train unit under-car suspension piece bottom plate equipment anti-separating lock comprises a fixing pin base which is provided with a loop pin base and is fixed through a locating bolt. The locating bolt is provided with an opening pin. The loop pin base is designed in a step type special-shaped hole mode. The fixing pin base and the loop pin base are made of high-intensity low-temperature-resisting steel. The motor train unit under-car suspension piece bottom plate equipment anti-separating lock is simple in structure, easy to manufacture, low in cost and convenient to mount, the probability of bottom plate equipment falling is greatly lowered, and the safety of vehicle operation is guaranteed.
Description
Technical field
The present invention relates to the anti-lock-off of suspender backing apparatus under a kind of motor train unit car, belong to rail traffic vehicles, particularly EMU backing apparatus field engineering field.
Background technology
Along with the appearance of the development of track traffic, particularly EMU, while speed improves, safety also needs to pay attention to further, and therefore, the anticreep of suspender under motor train unit car, particularly outer missing part requires very important.At present, carbon steel or aluminum alloy bottom plate equipment directly use fastener to be installed on equipment at the bottom of car, anticreep mode has double nuts, spring washer, retaining washer, screw rod with holes and is coated with when mounted plays screw threads for fastening agent etc., but all can't resolve just in case bolt et out of order base plate drops to the risk on track.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, the anti-lock-off of suspender backing apparatus under a kind of motor train unit car is provided.
Technical scheme of the present invention, under a kind of motor train unit car, the anti-lock-off of suspender backing apparatus, comprises fixing key seat, fixing key seat arranges kink key seat, and is fixed by dowel bolt; Dowel bolt is also provided with spring cotter.Described kink key seat is the design of step section groove.
Described fixing key seat and kink key seat adopt high-strength low-allow steel material.
Beneficial effect of the present invention: structure of the present invention is simple, and easy to manufacture, cost is low, easy for installation, greatly reduces the probability that backing apparatus drops, and guarantees the safety of car operation.

Description of reference numerals: 1, fixing key seat; 2, kink key seat; 3, dowel bolt; 4, spring cotter; 5, base plate connecting device; 6, backing apparatus; 7, fastener is connected.
Detailed description of the invention
Describe the present invention in detail below in conjunction with accompanying drawing, it illustrates principle of the present invention by example, other aspects of the present invention as the part of this specification sheets, and feature and advantage thereof also can become very clear by this detailed description.
As shown in Figure 1, the anti-lock-off of suspender backing apparatus under a kind of motor train unit car, comprises fixing key seat 1, and fixing key seat 1 arranges kink key seat 2, and is fixed by dowel bolt 3; Dowel bolt 3 is also provided with spring cotter 4.Described kink key seat 2 is the design of step section groove.
Described fixing key seat 1 and kink key seat 2 adopt high-strength low-allow steel material.
When the present invention uses, as shown in Figure 2, fixing key seat 1 is welded and fixed with base plate connecting device 5, and then backing apparatus 6 passes through to be connected fastener 7(and screw bolt and nut with base plate connecting device 5) connect fastening.
Kink key seat 2 is by profiled holes through after fixing key seat 1, and 90-degree rotation makes special-shaped Step Shaft in fixing key seat 1 just be stuck in the groove of kink key seat 2, fixes afterwards with dowel bolt 3 and spring cotter 4.
After connection fastener 7 lost efficacy, backing apparatus 6 also can be fixed by kink key seat 2, can not drop.And this anti-lock-off itself is also have secondary anti-failure structure, after dowel bolt 3 and spring cotter 4 all lost efficacy, kink key seat 2 and location key seat 1 are also blocked mutually by profiled holes axle and groove, limit relative movement thus kink key seat 2 is tightened together with fixing key seat 1.
Backing apparatus provided by the invention anti-lock-off kink key seat 2 adopts right-angled crossing abnormity location structure.Can ensure that location anticreep is locked in after dowel bolt 3 comes off, kink key seat 2 and fixing key seat 1 still can not relative movements, better carry out secondary mousing.
Fixing key seat 1 of the present invention and kink key seat 2 all adopt high-strength low-allow steel material, better harsh environment under adaptation car.
The present invention can be lost efficacy in the protection of backing apparatus one-level, and under the prerequisite that in anticreep lock construction, dowel bolt 3 and spring cotter 4 all lost efficacy, guaranteed that backing apparatus can not drop on track, avoid the generation of vehicle safety accident.
The foregoing is only the present invention's wherein a kind of embodiment, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improves, all should be included within protection scope of the present invention.
