[0038] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0040] Please refer to Figure 1-3 , Figure 1 This is a schematic diagram of a container locking device 100 provided on a cross beam 300 and a side beam 200 in an embodiment of the present application. Figure 2 for Figure 1 A top view of the container locking device 100 installed on the cross beam 300 and the side beam 200; Figure 3 An end view of a railway container car body.

[0041] Railway container vehicles are used to load containers. Railway container vehicles include railway container bodies, such as Figure 3 As shown, the railway container car body includes a cross beam 300, side beams 200 located on both sides of the cross beam 300, and a center beam 400 located between the two side beams 200. The cross beam 300, the center beam 400, and the side beams 200 are all fixedly connected. The side beams 200 and the center beam 400 extend along the length direction of the railway container car body, which is also the front-rear direction of the railway container car body. The cross beam 300 extends along the width direction of the railway container car body. The length direction and the width direction are perpendicular to each other. The length direction and the width direction can be referred to Figure 1-3 After the container is loaded on the railway container body, the container needs to be locked so that the container can be relatively stably supported on the railway container body. To this end, the railway container body is provided with a container locking device 100.

[0042] The structure of the container locking device 100 in this embodiment can be referred to Figure 4-5 understand, Figure 4 for Figure 1 A schematic structural diagram of the container locking device 100, wherein the first stopper 103 is in the first working position; Figure 5 for Figure 4 A schematic structural diagram of the first stopper 103 of the container locking device 100 being in the second working position.

[0043] The container locking device 100 in this embodiment includes a lock head 30, a first lock seat 10, a second lock seat 20 and a first stopper 103. The lock head 30 is as shown in FIG. Figure 4 As shown, the lock 30 includes a lock seat 302 and a head 301 protruding from the lock seat 302. The container is provided with a corresponding lock hole. When the container needs to be locked, the lock 30 can be inserted into the lock hole of the container to lock the container.

[0044] It should be noted that the container locking device 100 in this embodiment includes a first lock seat 10 and a second lock seat 20 that are independent of each other, that is, the first lock seat 10 and the second lock seat 20 are separately arranged, wherein the first lock seat 10 is used to be installed on the cross beam 300 of the railway container body, and the second lock seat 20 is used to be installed on the side beam 200 of the railway container body, that is, the two lock seats are installed on different beams of the railway container body, and the first lock seat 10 and the second lock seat 20 do not need to be connected, and can contact each other, and of course, a detachable connection is also possible. The railway container body is defined as having a center line extending in the length direction, and the direction close to the center line is the inside, and the opposite direction is the outside, then the first lock seat 10 is located on the inside of the second lock seat 20, and the second lock seat 20 is located on the outside of the first lock seat 10. The first lock seat 10 and the second lock seat 20 are both used to limit the lock head 30 to ensure that the lock head 30 is in a relatively fixed position.

[0045] In addition, the lock head 30 of the container locking device 100 is slidably matched with the first lock seat 10 and the second lock seat 20. The lock head 30 can slide from the first lock seat 10 to the second lock seat 20, or from the second lock seat 20 to the first lock seat 10. The sliding direction is the width direction of the railway container body. The lock head 30 can slide from the first lock seat 10 to the second lock seat 20 from the inside to the outside, or from the second lock seat 20 to the first lock seat 10 from the outside to the inside. The first lock seat 10 and the second lock seat 20 are arranged in this way. When the lock head 30 needs to lock the container, the lock head 30 can be located at the first lock seat 10 to lock the container. When the container does not need to be locked, the lock head 30 can be withdrawn from the first lock seat 10 to the second lock seat 20 to unlock.

[0046] For specific application scenarios, please refer to Figure 1 , 4 5. The container locking device 100 is arranged in the middle of the railway container body in the length direction, and locking mechanisms for locking the containers are also arranged at both ends of the railway container in the length direction. The container locking device 100 includes two locks 30. When two containers of the first size specification arranged along the length direction are loaded on the railway container body, the ends of the two containers that are far away from each other are respectively locked by the locking mechanisms corresponding to the two ends of the railway container body, but the ends of the two containers that are close to each other are respectively locked by the two locks 30 of the container locking device 100. At this time, the two locks 30 are both located at the position of the first lock seat 10, that is, each lock 30 is responsible for locking a container of the first size specification.

[0047] When a container of the second size is loaded on the railway container body, that is, the length of the container of the second size is longer than that of the container of the first size, which is twice the length of the container of the first size. At this time, the two ends of the container of the second size can be directly locked by the locking mechanism at the two ends of the railway container body. If the lock head 30 of the container locking device 100 located in the middle is still in the position of the first lock seat 10, it will correspond to the middle of the container of the second size, which will interfere with the loading of the container. Therefore, the two lock heads 30 can slide to the position of the second lock seat 20 located on the outside to avoid the container of the second size. It can be seen that the sliding setting of the lock head 30 of the container locking device 100 can be adapted to different application scenarios and improve the flexibility of locking. It can be seen that the container locking device 100 can be set with one, two or other number of lock heads 30, which can be designed according to the application scenario.

[0048] In addition, the container locking device 100 in this embodiment further includes a first stopper 103. The first stopper 103 can limit the lock head 30 from sliding relative to the first lock seat 10 in the first working position. When the first stopper 103 is in the second working position, the lock head 30 can slide relative to the first lock seat 10 or the second lock seat 20. Figure 4 , 5 Specifically, the first stopper 103 is a baffle structure, and the first stopper 103 can be rotatably connected to the first lock seat 10. When the lock head 30 is located in the first lock seat 10 to lock the container, in order to prevent the lock head 30 from being separated from the first lock seat 10 and affecting the reliability of locking, the first stopper 103 can be rotated to the sliding path of the lock head 30 to limit the lock head 30 from sliding and separating from the first lock seat 10. Figure 4 The first stopper 103 is in the locked first working position, Figure 5 The first stopper 103 rotates away from the sliding path of the lock head 30 to release the locking restriction on the lock head 30. Of course, the first stopper 103 is not limited to being connected to the first lock seat 10, for example, it can be set to translate; the first stopper 103 is not limited to being connected to the first lock seat 10, and can also be connected to the second lock seat 20, as long as it can limit the lock head 30 from sliding relative to the first lock seat 10.

[0049] It is not difficult to understand that in the embodiment of the present application, the lock seat for installing the lock head 30 on the container locking device 100 is divided into two independent parts, namely the first lock seat 10 and the second lock seat 20. In this way, the first lock seat 10 can be installed on the crossbeam 300, and the second lock seat 20 can be installed on the side beam 200. Compared with the technical solution of welding the lock seat to the crossbeam 300 mentioned in the background technology, it is obvious that the arrangement method of the embodiment of the present application can arrange the lock seats on the crossbeam 300 and the side beam 200 respectively, which not only meets the sliding stroke requirements of the lock head 30, but also can be carried by the side beam 200 and the crossbeam 300 respectively. The layout is more reasonable and the connection is more reliable.

[0050] The first lock seat 10 and the second lock seat 20 are both provided with a slide rail or a slide groove that cooperates with the lock head 30. Figure 4 , 5 In the embodiment, the first lock seat 10 and the second lock seat 20 are both provided with slide grooves, namely the first slide groove 102a and the second slide groove 201a, which extend along the width direction of the railway container body, and the lock head 30 is provided with a slide rail. For example, the cross section of the lock head seat 302 of the lock head 30 is roughly an inverted T shape, and the transverse part of the T shape serves as a slide rail. At least part of the slide rail is inserted into the slide groove for sliding, which can not only guide the sliding, but also limit the lock head 30 in the front and rear directions. It can be known that the lock head 30 is provided with a slide groove, and the first lock seat 10 and the second lock seat 20 are also provided with a slide rail.

[0051] At this time, the container locking device 100 further includes an adjustment pad 50, which is located at the bottom of the first lock seat 10 and can be used to adjust the height of the bearing surface of the first lock seat 10 so that the bearing surfaces of several locking mechanisms for locking the container can be flush to ensure the stability and reliability of locking. The adjustment pad 50 can be one or more and can be set according to actual needs.

[0052] Please continue to combine Figure 6 , 7 understand, Figure 6 for Figure 5 A cross-sectional view of the container locking device 100 along the width direction; Figure 7 for Figure 5 An enlarged view of the middle part, in which one of the lock heads 30 and the first stopper 103 is removed, is provided to facilitate understanding of the various parts of the container locking device 100. Figure 7 Different colors are used to indicate different parts of the structure.

[0053] In this embodiment, the first lock seat 10 and the second lock seat 20 are specifically provided with a slide groove. Here, it is defined that the first lock seat 10 is provided with a first slide groove 102a that cooperates with the lock head 30, and the second lock seat 20 is provided with a second slide groove 201a that cooperates with the lock head 30. Figure 6As shown, the height D1 of the first chute 102a is less than the height D2 of the second chute 201a, the top of the first chute 102a can be lower than the top of the second chute 201a, and the bottom of the first chute 102a is not lower than the bottom of the second chute 201a. In this way, if there is a height difference between the first lock seat 10 and the second lock seat 20, the lock head 30 can also slide from the first chute 102a into the second chute 201a. In this embodiment, the height D1 of the first chute 102a is set to be relatively low, which is better adapted to the slide rail of the lock head 30 and is roughly equal to the height of the slide rail of the lock head 30. When the lock head 30 locks the container, the lock head 30 is better limited, and the cooperation with the lock hole can better meet the locking requirements. The second chute 201a is mainly used to accept the withdrawal of the lock head 30 from the first chute 102a, and the height is set to be relatively high without affecting the position requirement of the lock head 30.

[0054] Please see Figure 4 , 5 7. The first lock base 10 in this embodiment includes a lock base body 102 and a lock base substrate 101. The lock base body 102 is disposed on the lock base substrate 101. The lock head 30 is supported on the lock base substrate 101 and slidably cooperates with the lock base body 102. The lock base body 102 is provided with two notches 102b, which penetrate the lock base body 102 in the height direction. Figure 5 It can be seen from the figure that the lock seat body 102 is a Japanese-shaped structure with one side open, and the first slide grooves 102a are set on the two opposite side walls of each notch 102b. The lock seat 302 of the lock 30 is accommodated in the notch 102b. The slide rail is a part of the lock seat 302, and the slide rail is inserted into the first slide groove 102a. Figure 6 As shown, the first slide groove 102a and the second slide groove 201a in this embodiment are both L-shaped grooves. The lock head seat 302 in the first lock seat 10 is supported on the lock seat base plate 101. The lock seat base plate 101 and the first slide groove 102a are combined into a groove structure, which can better limit the slide rail of the lock head 30.

[0055] like Figure 4 As shown, along the vertical projection, the projection surface of the lock base body 102 is located within the projection surface of the lock base substrate 101. On the projection surface, the portion of the lock base substrate 101 outside the lock base body 102 can be used for riveting with the crossbeam 300 of the railway container body. In this way, the portion of the lock base substrate 101 surrounding the lock base body 102 can be processed with a riveting hole, and the rivet 40 can pass through the lock base substrate 101 to be riveted with the crossbeam 300, which can reduce welding and achieve green assembly.

[0056] Continue to refer Figure 4 , 5It is understood that the container locking device 100 in this embodiment further includes a second stopper 202, which is detachably connected to the second lock seat 20, and is used to limit the lock head 30 from being separated from the second lock seat 20 in a direction away from the first lock seat 10. The second stopper 202 is specifically a rod-shaped structure, and the second lock seat 20 specifically includes three lock seat blocks 201, which can be riveted to the side beam 200, and there is an accommodation space between two adjacent lock seat blocks 201. When the lock head 30 slides from the first lock seat 10 into the second lock seat 20, it can slide into the accommodation space of the two adjacent lock seat blocks 201, and the inner opening of the accommodation space can be sealed by the first stopper 103, and the outer opening of the accommodation space can be sealed by the second stopper 202. During normal operation, the second stopper 202 is in a sealed state, the first stopper 103 is opened, the lock head 30 can slide into the second lock seat 20, the first stopper 103 is closed, and the lock head 30 is located in the first lock seat 20, or the first stopper 103 is opened, the lock head 30 slides from the second lock seat 20 into the first lock seat 10, the first stopper 103 is closed, and the lock head 30 is limited in the first lock seat 10, which can be used to stably lock the container. The second stopper 202 is detachably connected to the second lock seat 20, so when the lock head 30 needs to be repaired or replaced, the second stopper 202 can be directly removed, and the lock head 30 can slide from the first lock seat 10 into the second lock seat 20, and then slide out from the second lock seat 20, so that disassembly and assembly are more convenient.

[0057] The second lock base 20 may be provided with a connection hole, specifically as follows Figure 4 As shown, each lock seat block 201 is provided with a connection hole on its outer side, and the two ends of the second stopper 202 are respectively fixedly connected to the two lock seat blocks 201 by connecting nails. It can be known that the second stopper 202 and the second lock seat 20 can also be connected by bolts, clamping or other connection methods.

[0058] The first lock seat 10 of the container locking device 100 can be riveted to the cross beam 300, and the second lock seat 20 can be riveted to the middle of the side beam 200. Riveting is used as much as possible to reduce welding pollution and achieve green connection. The first lock seat 10 and the second lock seat 20 are set independently of each other, which is also conducive to the independent riveting of the two with the corresponding cross beam 300 and side beam 200. Figure 1 It is understood that the cross beam 300 and the side beam 200, and the cross beam 300 and the middle beam 400 in this embodiment are also connected by riveting to achieve the effect of riveting as much as possible.

[0059] Specifically, Figure 1 , 3As shown, the end of the cross beam 300 in this embodiment is riveted to the bottom of the side beam 200, so that the upper surface of the cross beam 300 is lower than the upper surface of the side beam 200. The lock seat substrate 101 in this embodiment can increase the height of the lock seat body 102 to reduce the height difference between the first lock seat 10 and the second lock seat 20, which is conducive to the lock head 103 sliding between the first lock seat 10 and the second lock seat 20.

[0060] In this embodiment, the side beam 200 is specifically a U-shaped structure, specifically including a side top plate 201, a side plate 202, and a side bottom plate 203, and the side top plate 201 and the side bottom plate 203 are arranged opposite to each other. The cross beam 300 includes a cross top plate 301 and a first cross side plate 302 and a second cross side plate (not shown in the figure) located at the front and rear sides of the cross top plate 301. The cross section of the cross beam 300 is also U-shaped. The transverse end of the cross beam 300 can be inserted between the side top plate 201 and the side bottom plate 203 of the side beam 200, and the cross top plate 301 and the side top plate 201 are riveted. The first cross side plate 302 and the second cross side plate both have flanges to abut against and rivet the side plate 202 of the side beam 200. The end of the cross beam 300 is inserted into the side beam 200 and riveted at the same time, and the connection is more reliable.

[0061] Exemplarily, the railway container car body in this embodiment further includes a center beam 400, such as Figure 3 As shown, the middle beam 400 is connected to the middle part of the cross beam 300. The cross beam 300 in this embodiment specifically includes two parts distributed in the transverse direction, each of which is fixedly connected to the middle beam 400. The connection method can also be as follows: Figure 3 At this time, the railway container body also includes a support seat 500, which is riveted between the side of the middle beam 400 and the bottom of the cross beam 300, that is, the support seat 500 is riveted and fixed to the middle beam 400 and the cross beam 300, so as to enhance the reliability of the connection between the middle beam 400 and the cross beam 300 and meet the strength requirements under the premise that the cross beam 300 and the middle beam 400 are riveted.

[0062] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
