Description

Technical Field

[0001] This utility model relates to a container locking device, specifically a railway container quick locking device, and belongs to the field of container locking technology. Background Technology

[0002] Container locking is an operation that uses special devices to secure containers to railway flatcars to prevent them from shifting or falling during transportation. In railway traffic management, when freight trains are loading containers, locking devices are used to secure them after the containers are hoisted onto the flatcars. This is a crucial step in ensuring the safe departure of the train.

[0003] A utility model patent with authorization announcement number CN209701427U discloses a quick locking and unlocking device for marine containers. It utilizes four locking rods designed at the four corners of the container's vertical surface. During loading, the locking rod head of the lashing bridge is inserted into the locking rod's closing hole, and the lashing bridge's locking rod head engages with the locking block inside the locking rod's closing hole. Simultaneously, the locking rod is pushed upwards, expelling the locking rod head from the locking rod's closing hole. When containers are stacked again, the locking rod head of the lower container engages with the locking block inside the locking rod's closing hole of the upper container, thus locking the containers and lashing bridge together. Simultaneously, it can... The containers are locked sequentially. Simply align the four locking rod holes of the container with the locking rod heads and lower it; it will automatically lock without needing to be tied or secured again. Using unlocking blocks designed within the locking rod holes, when the container needs to be unloaded, the crane holds the four locking rod heads on top of the container and pulls the locking rod heads upwards. At this time, the locking rod locking blocks fixed to the locking rods push upwards against the unlocking blocks, causing the unlocking blocks to compress inwards. The unlocking blocks, through the locking block connecting rod, drive the locking blocks inwards, thus unlocking the locking rod heads from the locking blocks. The container can then be unloaded by pulling the locking rod heads, making the process convenient, quick, and efficient.

[0004] While the aforementioned technical solutions can quickly lock containers, the locking structure is time-consuming and labor-intensive to remove, and lacks a quick locking structure to improve container unlocking and locking, resulting in relatively limited ease of use for the locking device. Therefore, this paper proposes a rapid locking device for railway containers. Utility Model Content

[0005] This utility model proposes a railway container quick locking device to solve the problem that the existing technology lacks a quick locking structure that can improve the unlocking and locking of containers, resulting in the relatively general ease of use of the locking device.

[0006] This utility model is achieved through the following technical solution: a railway container quick locking device, including a base, and a quick locking mechanism is provided on the outside of the base; The quick-locking mechanism includes an adjusting plate with an adjusting bolt threaded to its inner wall. A top cone is fixedly connected to the upper surface of the adjusting plate. Four arc-shaped limiting blocks are provided inside the base. A positioning post is fixedly connected to one side of each arc-shaped limiting block near the base. A return spring is sleeved on the outer surface of each positioning post. A pre-installed corner seat is slidably connected to the outer surface of the base. Four positioning holes are opened on the outer surface of the pre-installed corner seat. An auxiliary bearing is fixedly connected to the inner wall of the base.

[0007] Specifically, the outer surface of the adjusting plate is slidably connected to the interior of the base, the outer surface of the adjusting bolt is threadedly connected to the inner wall of the adjusting plate, the outer surface of each arc-shaped limiting block is in contact with the outer surface of the top cone, the outer surface of each positioning column is slidably connected to the interior of the base, the two ends of each return spring are in contact with the inner wall of the base and the outer surface of the arc-shaped limiting block, the inner ring of the auxiliary bearing is fixedly connected to the outer surface of the adjusting bolt, and mounting plates are fixedly connected to both sides of the base, with several identical mounting holes opened on the upper surface of each mounting plate.

[0008] Furthermore, an anti-slip sleeve is fixedly connected to the outer surface of the adjusting bolt, and several identical anti-slip protrusions are fixedly connected to the outer surface of the anti-slip sleeve.

[0009] The base has a support plate fixedly connected to its outer surface, and a pull rod is slidably connected to the inside of the support plate.

[0010] Preferably, a positioning block is fixedly connected to the right end of the pull rod, and several identical positioning grooves are opened on the outer surface of the adjusting bolt, wherein the inner wall of one of the positioning grooves is in contact with the outer surface of the positioning block.

[0011] Furthermore, a return spring is fitted onto the outer surface of the pull rod, and the two ends of the return spring are in contact with the left side of the positioning block and the right side of the support plate, respectively.

[0012] This utility model provides a quick locking device for railway containers, which has the following beneficial effects: This railway container quick-locking device allows multiple pre-installed corner seats to be pre-assembled on the bottom of the container. Using a quick-locking mechanism on the outside of the base, and through the threaded engagement of the adjusting bolt and the adjusting plate, supported by auxiliary bearings, rotating the adjusting bolt drives the adjusting plate to rise and fall stably. When the adjusting plate raises the top cone, it presses against four arc-shaped limit blocks, causing these blocks to overcome the spring force of the return spring and push the positioning pins out. These positioning pins, in conjunction with the pre-installed corner seats sliding on the outside of the base and their positioning holes, quickly lock the container. To unlock, rotating the adjusting bolt in the opposite direction lowers the top cone, causing the return spring to spring back and pull the arc-shaped limit blocks out. The block resets, the positioning pin disengages from the positioning hole, and quick unlocking is achieved. The overall structure requires no complicated operation. It ensures the stability of the lock through the cooperation of the arc-shaped limit block and the positioning pin, preventing the container from shifting and falling during transportation. It also greatly improves the convenience of locking and unlocking the container by relying on a simple bolt adjustment and spring reset mechanism. It effectively solves the problem that the lack of a quick locking structure in existing devices leads to the general ease of use. In addition, the sliding design of the pre-installed corner seat can adapt to different installation requirements, further enhancing the practicality of the device and avoiding the problem that the lack of a quick locking structure that can improve the unlocking and locking of the container leads to the general ease of use of the locking device.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-4 This utility model provides a quick locking device for railway containers, including a base 1. A quick locking mechanism 2 is provided on the outer side of the base 1. The quick locking mechanism 2 includes an adjusting plate 201. An adjusting bolt 209 is threadedly connected to the inner wall of the adjusting plate 201. The outer surface of the adjusting plate 201 is slidably connected to the interior of the base 1. The outer surface of the adjusting bolt 209 is threadedly connected to the inner wall of the adjusting plate 201. Assembly plates 3 are fixedly connected to both sides of the base 1. Several identical assembly holes 4 are opened on the upper surface of each assembly plate 3. The assembly plates 3 are fixed to both sides of the base 1. The assembly holes 4 are opened on the upper surface of the assembly plates 3, which facilitates fixing the base 1 to the railway flatcar by bolts and other connecting parts. This adapts to the installation requirements of different types of railway flatcars and improves the versatility of the device.

[0017] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The upper surface of the adjusting plate 201 is fixedly connected to a top cone 202. The base 1 has four arc-shaped limiting blocks 203 inside. The outer surface of each arc-shaped limiting block 203 is in contact with the outer surface of the top cone 202. The outer surface of the adjusting bolt 209 is fixedly connected to an anti-slip sleeve 5. The outer surface of the anti-slip sleeve 5 is fixedly connected to several identical anti-slip protrusions 6. The anti-slip sleeve 5 is fixed to the outer surface of the adjusting bolt 209. The anti-slip protrusions 6 are evenly distributed on the outer surface of the anti-slip sleeve 5, which can increase the friction between the operator's hand and the adjusting bolt 209, and prevent the hand from slipping when rotating the adjusting bolt 209. Especially in humid or oily environments, it can still ensure stable operation and improve the safety and convenience of use.

[0018] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3Each arc-shaped limiting block 203 is fixedly connected to a positioning post 204 on one side near the base 1. The outer surface of each positioning post 204 is slidably connected to the inside of the base 1. Each positioning post 204 is fitted with a return spring 205 on its outer surface. The two ends of each return spring 205 are in contact with the inner wall of the base 1 and the outer surface of the arc-shaped limiting block 203, respectively. A support plate 7 is fixedly connected to the outer surface of the base 1. A pull rod 8 is slidably connected inside the support plate 7. The support plate 7 is fixed to the outer surface of the base 1 to provide sliding support for the pull rod 8. The pull rod 8 can slide inside the support plate 7. By pulling the pull rod 8, other positioning structures can be moved to prepare for the subsequent fixing of the position of the adjusting bolt 209. The structure is simple and the operation is flexible.

[0019] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The outer surface of the base 1 is slidably connected to a pre-installed corner bracket 206. Multiple pre-installed corner brackets 206 can be pre-welded or fixedly installed on the bottom of the corresponding container. The outer surface of the pre-installed corner bracket 206 is provided with four positioning holes 207. After the adjusting plate 201 drives the top cone 202 to rise, the top cone 202 can push open the four arc-shaped limiting blocks 203, so that the positioning post 204 can be inserted into the corresponding positioning hole 207, thereby locking the relative position of the base 1 and the pre-installed corner bracket 206. The right end of the pull rod 8 is fixedly connected to a positioning block 9. The outer surface of the adjusting bolt 209 is provided with several identical positioning grooves 10. The inner wall of one of the positioning grooves 10 is in contact with the outer surface of the positioning block 9. The positioning block 9 is fixed to the right end of the pull rod 8. The positioning grooves 10 are evenly opened on the outer surface of the adjusting bolt 209. When the positioning block 9 is inserted into the positioning groove 10, it can restrict the rotation of the adjusting bolt 209, avoid the adjusting bolt 209 from loosening due to vibration during container transportation, prevent the positioning post 204 from dislodging from the positioning hole 207, and further ensure the reliability of locking.

[0020] Please refer to this carefully. Figure 2 and Figure 3 An auxiliary bearing 208 is fixedly connected to the inner wall of the base 1. The inner ring of the auxiliary bearing 208 is fixedly connected to the outer surface of the adjusting bolt 209. A return spring 11 is sleeved on the outer surface of the pull rod 8. The two ends of the return spring 11 are in contact with the left side of the positioning block 9 and the right side of the support plate 7, respectively. The return spring 11 can provide a continuous rightward elastic force to the positioning block 9, ensuring that the positioning block 9 always remains inserted into the positioning groove 10 when there is no external force pulling it. There is no need to manually maintain the position of the positioning block 9, which improves the convenience of use and locking stability of the device.

[0021] When using this utility model: Before use, the base 1 is fixed to the railway flatcar with bolts through the assembly holes 4 on the assembly plate 3. At the same time, multiple pre-installed corner brackets 206 are pre-installed on the bottom surface of the container to ensure that the pre-installed corner brackets 206 can slide and cooperate with the outer surface of the base 1.

[0022] When locking, first pull the lever 8 to the left. The lever 8 causes the positioning block 9 to disengage from the positioning groove 10 of the adjusting bolt 209. At this time, the return spring 11 is compressed. Then, rotate the adjusting bolt 209. Since the adjusting bolt 209 is threadedly connected to the adjusting plate 201, and the auxiliary bearing 208 provides support and resistance reduction for the adjusting bolt 209, the rotation of the adjusting bolt 209 will drive the adjusting plate 201 to rise steadily along the inside of the base 1. The rise of the adjusting plate 201 will drive the top cone 202 to rise synchronously. The top cone 202 will press the four arc-shaped limit blocks 203. The arc-shaped limit blocks 203 will overcome the elastic force of the return spring 205 and move outward, thereby pushing the positioning post 204 out of the base 1. When the positioning post 204 is inserted into the positioning hole 207 of the pre-installed corner seat 206, stop rotating the adjusting bolt 209, release the lever 8, and the return spring 11 will rebound and push the positioning block 9 into the positioning groove 10 corresponding to the adjusting bolt 209, fixing the position of the adjusting bolt 209 and completing the container locking.

[0023] When unlocking, pull the lever 8 to the left again to disengage the positioning block 9 from the positioning groove 10. Rotate the adjusting bolt 209 in the opposite direction. The adjusting plate 201 drives the top cone 202 to descend. The squeezing force of the top cone 202 on the arc-shaped limit block 203 disappears. The return spring 205 rebounds and pulls the arc-shaped limit block 203 back to its original position. The positioning column 204 retracts into the base 1 along with the arc-shaped limit block 203 and disengages from the positioning hole 207. At this time, the container along with the pre-installed corner seat 206 can be removed from the base 1 to complete the unlocking. The design of the entire railway container quick locking device effectively solves the problem that the lack of a quick locking structure that can improve the unlocking and locking of the container results in the relatively general ease of use of the locking device.
