Description

Technical Field

[0001] This utility model relates to the field of wide-gauge vehicle technology, and in particular to a bottom-opening wide-gauge vehicle with a double-locking door structure. Background Technology

[0002] Bottom-opening wide-gauge wagons are vehicles with an openable funnel-shaped door at the bottom, enabling rapid unloading via pneumatic, manual, or tipper control. During unloading, materials are discharged from the bottom of the wagon by gravity, significantly increasing efficiency compared to traditional manual or mechanical loading and unloading methods.

[0003] Existing bottom-opening wide-gauge vehicles generally lock the bottom plate using a lock with a hook (the lock is rotatably mounted on the frame and uses the hook to form a hook support for the bottom plate). When the wide-gauge vehicle travels on bumpy roads, the lock is prone to loosening due to vibration or impact, greatly increasing the risk of unlocking. Therefore, this application provides a bottom-opening wide-gauge vehicle with a double-locking door structure to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a bottom-opening wide-rail vehicle with a double-locking door structure to solve the problem that the single-locking structure in the prior art easily increases the risk of automatic unlocking.

[0005] To achieve the above objectives, this application provides the following technical solution: a bottom-opening wide-gauge vehicle with a double-locking door structure, comprising a frame, a car body and a bolster respectively mounted on the upper and lower ends of the frame, a wheelset mounted on the bolster, a double-opening bottom door at the bottom of the car body, an L-shaped plate mounted on the frame for supporting the bottom door in the open state, a first lock head with a hook portion rotatably mounted on the frame, a contact portion adapted to the hook portion on the bottom door, and a second lock head rotatably mounted on the frame via a pivot, the second lock head being fan-shaped, the outer wall of the second lock head contacting the outer wall of the first lock head.

[0006] In a preferred embodiment of this invention, the outer wall of the second lock head is arc-shaped, and the outer wall of the first lock head is provided with an arc-shaped groove that is consistent with the outer wall of the second lock head.

[0007] Both the first lock head and the second lock head are rotatably mounted on the mounting plate, and the mounting plate is fixedly mounted on the vehicle frame;

[0008] A stop bar is fixed to the second lock head, and the stop bar is positioned away from the pivot.

[0009] In a preferred embodiment of this invention, both the second lock head and the first lock head are provided with through holes that are adapted to their shapes.

[0010] In a preferred embodiment of this invention, the outer walls of both the first lock head and the second lock head are made into smooth surfaces.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] This utility model has a reasonable structure. The wide-gauge vehicle is equipped with a double locking structure, which reduces the risk of accidental unlocking and enhances the fault tolerance of the system.

[0013] In this invention, the outer wall of the second lock head is arc-shaped, and the outer wall of the first lock head is provided with an arc-shaped groove that matches the outer wall of the second lock head. The first lock head and the second lock head form a surface contact. Compared with point contact, surface contact has a larger contact area, which reduces the pressure per unit area and reduces wear and deformation. Surface contact helps to disperse stress, reduce stress concentration, and improve the strength and stability of the component. Surface contact increases friction, provides a better locking effect, and reduces the risk of accidental unlocking. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figure 1-3 The illustrated bottom-opening wide-rail vehicle with a double-locking door structure includes a frame 3. A carriage 1 and a bolster 4 are respectively mounted on the upper and lower ends of the frame 3. Wheel sets 5 are mounted on the bolster 4. The bottom of the carriage 1 is provided with a double-opening bottom door 7. An L-shaped plate 6 is mounted on the frame 3 to support the bottom door 7 in the open state. A first lock head 9 with a hook part is rotatably mounted on the frame 3. A contact part 8 adapted to the hook part is provided on the bottom door 7. A second lock head 10 is rotatably mounted on the frame 3 via a pivot. The second lock head 10 is fan-shaped, and the outer wall of the second lock head 10 contacts the outer wall of the first lock head 9.

[0022] In use, the hook part of the first lock head 9 hooks onto the contact point 8 on the bottom door 7, so that the hook part supports the bottom door 7 and locks the bottom door. At the same time, the second lock head 10 is rotated so that the outer wall of the second lock head 10 abuts against the outer wall of the first lock head 9. At this time, the second lock head 10 can no longer rotate. The component of the gravity of the second lock head 10 acts on the first lock head 9 to form a double lock.

[0023] A second locking head 10 is provided. The gravity of the second locking head 10 acts on the first locking head 9, hindering the first locking head 9 and preventing it from loosening. The cooperation between the first locking head 9 and the second locking head 10 forms a double locking system. During railway operation, due to vibration and impact, a single locking mechanism may accidentally unlock. The double locking system utilizes the self-stabilizing characteristics of the sector block (the design of the sector block allows it to automatically adjust its position during movement, maintaining a stable pressure on the first locking head 9, thus improving the system's self-stability). The gravitational component acts on the first locking head 9, reducing the risk of accidental unlocking and enhancing the system's fault tolerance.

[0024] As a preferred embodiment of this invention, the outer wall of the second lock head 10 is arc-shaped, and the outer wall of the first lock head 9 is provided with an arc-shaped groove 2 that is the same as the outer wall of the second lock head 10.

[0025] Both the first lock head 9 and the second lock head 10 are rotatably mounted on the mounting plate 13, and the mounting plate 13 is fixedly mounted on the vehicle frame 3.

[0026] A stop bar 11 is fixed on the second lock head 10, and the stop bar 11 is set away from the pivot.

[0027] Rotating the second lock head 10 causes a portion of its outer surface to rotate into the arc-shaped groove 2. The stop bar 11 then contacts the mounting plate 13, preventing further rotation of the second lock head 10. At this point, the first lock head 9 and the second lock head 10 form a surface contact. Compared to point contact, surface contact has a larger contact area, reducing pressure per unit area and minimizing wear and deformation. Surface contact also helps disperse stress, reducing stress concentration and improving the strength and stability of the components. Furthermore, surface contact increases friction, providing a better locking effect and reducing the risk of accidental unlocking.

[0028] In a preferred embodiment of this invention, both the second lock head 10 and the first lock head 9 are provided with through holes 12 that are adapted to their shapes.

[0029] The through-hole 12 not only reduces weight but also helps to disperse stress, reduce material fatigue or cracks caused by stress concentration, and improve the service life of the component.

[0030] In a preferred embodiment of this invention, the outer walls of both the first lock head 9 and the second lock head 10 are made of smooth surfaces.

[0031] This can reduce the friction between the first lock head 9 and the second lock head 10, thus avoiding excessive wear.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
