Abstract
The utility model discloses an anti-rotation stop dog of a metro vehicle, which is welded on the upper surface of a steering bogie and comprises a vertical stop dog surface extending outwards; arc-shaped transition is adopted from the stop dog surface to a welding surface; furthermore, the anti-rotation stop dog is further provided with a lifting hole; and the stop dog surface is a circular-arc surface. The anti-rotation stop dog of the metro vehicle adequately considers the different requirements of different clients on the metro vehicle, and combines the anti-rotation stop dog and a steering bogie lifting device of the vehicle into one integral structure, thereby not only meeting the anti-rotation requirements of the metro vehicle, but also realizing a lifting function. Is not only the process simplified, and the production efficiency improved, but also the design cost and the manufacturing cost are decreased; furthermore, the safety running of the metro vehicle can be guaranteed; and the check and the subsequent maintenance work are convenient.
Description
Technical field
The utility model relates to a kind of railcar rotate-proof stop catch.
Background technology
In the design of railcar, the lifting that prevents counterrotating rotate-proof stop catch of vehicle and bogie truck and bogie truck is the key issue that must consider.Railcar design in the past, rotate-proof stop catch and bogie lifting device are two diverse structures, this had not both met the requirement of vehicle weight-saving, had increased workman's work capacity simultaneously yet.
Summary of the invention
The utility model technical matters to be solved is, overcomes the above-mentioned shortcoming of prior art, and a kind of railcar rotate-proof stop catch is provided, and simplified structure reduces parts, enhances productivity.
In order to solve above technical matters; The railcar rotate-proof stop catch that the utility model provides is welded in the bogie truck upper surface, it is characterized in that: have outwardly directed vertical stop surface; Said stop surface to face of weld is an arc-shaped transition, and this rotate-proof stop catch also offers hole for hoist.
Further, said stop surface is an arc surface.
The utility model takes into full account the demands of different of different clients to railcar, the rotate-proof stop catch of vehicle and bogie lifting device is united two into one make an integral structure, can satisfy the requirement of railcar anti-rotation, has hoisting function again.Both simplify technology, improved production efficiency, reduced design and manufacture cost again, and can guarantee the safe operation of railcar, made things convenient for the follow-up handling labor of cross-check sum.
This subway vehicle rotate-proof stop catch, the structure design thinking is simple, convenient in application; Can not only satisfy the requirement of vehicle anti-rotation, and have the function of bogie truck lifting, both simplify technology; Improved production efficiency; Reduce design and manufacture cost again, and can guarantee the safe operation of railcar, can be widely used in all railcars both at home and abroad.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is this subway vehicle rotate-proof stop catch structural representation.
The specific embodiment
As shown in Figure 1, be the railcar rotate-proof stop catch of present embodiment, it is welded in the bogie truck upper surface, and it has outwardly directed vertical stop surface 1, and said stop surface 1 to face of weld 3 is an arc-shaped transition, and this rotate-proof stop catch also offers hole for hoist 4.Said stop surface 2 is an arc surface.The arc-shaped transition of stop surface 1 to face of weld 3 has been guaranteed bulk strength.
Can set a gap width according to subway actual track situation between rotate-proof stop catch and the vehicle side bar; When the subway vehicle passes through little curve; Inevitably relative rotation can occur between car body and the bogie truck, during gap width that surpass to set when the amount of spin of car body is excessive, rotate-proof stop catch begins to work; Prevent that car body from excessively rotating, make railcar pass through curve smoothly.The contact surface of rotate-proof stop catch (stop surface) has been designed to the shape of circular arc; This circular arc can guarantee that railcar is through little curve the time; Mild transition contacts between rotate-proof stop catch and the car body side bar; Guaranteed that not only the passenger takes the traveling comfort of railcar, safety, and the protective effect that car body itself is also played, the scuffing of having avoided car body.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. the railcar rotate-proof stop catch is welded in the bogie truck upper surface, it is characterized in that: have outwardly directed vertical stop surface, said stop surface to face of weld is an arc-shaped transition, and this rotate-proof stop catch also offers hole for hoist.
2. railcar rotate-proof stop catch according to claim 1 is characterized in that: said stop surface is an arc surface.
