A monitoring device for unlocking containers on a railcar

Abstract

This utility model provides a monitoring device for the unlocking of containers on a rail-mounted crane. It includes a camera mounted on the support leg of the rail-mounted crane facing the container, a switch electrically connected to the camera, a video recorder electrically connected to the switch, and a display screen electrically connected to the video recorder. By mounting the camera on the support leg of the rail-mounted crane and electrically connecting it to the display screen at the back end, workers can directly observe whether the locks on the container and the railway container flatcar are unlocked. This eliminates the need for workers to be on-site to observe the unlocking status, thus avoiding certain dangers. Furthermore, a cantilever structure is formed by a winch, a first crossbar, and a boom. The winch, via a steel wire rope, can move the camera positioned below the boom between the two containers, allowing each camera to observe the unlocking status of at least two containers, thereby saving overall project costs.

Description

Technical Field

[0001] This utility model relates to the field of container inspection, and in particular to a monitoring device for unlocking containers on rail cranes. Background Technology

[0002] In railway freight operations, when a rail crane is lifting containers from a railway container flatcar, a key safety procedure applies: when the container is lifted to a height of approximately 100mm above the flatcar surface, it must remain suspended for at least 3 seconds during the continued lifting process. This step provides operators with time to check whether the locks on the container and the railway container flatcar have been successfully unlocked. This effectively prevents the container from being lifted along with the railcar due to lock entanglement, thus avoiding damage to the railway container flatcar.

[0003] Under current technological conditions, to ensure the strict implementation of the above-mentioned operational procedures, a relatively traditional manual method is usually adopted. Specifically, personnel are assigned to record the entire operation process on video, while another person is responsible for checking whether the locking device has been successfully disengaged and directing the rail crane operator to carry out the hoisting operation. However, this method of relying on manual on-site operation has obvious drawbacks. Due to the complex environment of the operation site and the inherent danger of rail crane hoisting operations, when personnel are on-site performing a series of tasks such as video recording, locking device inspection, and directing the operator to hoist, they inevitably face high safety risks, posing a potential threat to their lives. Utility Model Content

[0004] The purpose of this invention is to provide a monitoring device for the unlocking of containers on rail machinery, in order to solve the safety risks that exist when workers need to enter the work site to observe the unlocking status of container locks at close range.

[0005] To solve the above-mentioned technical problems, this utility model provides a monitoring device for unlocking containers on a rail machine, including a camera installed on the support leg of the rail machine facing the container, a switch electrically connected to the camera, a video recorder electrically connected to the switch, and a display screen electrically connected to the video recorder.

[0006] In a preferred embodiment, a first hinge support and a winch are provided on the support leg facing the container on the side of the rail machine. A first crossbar is provided on the first hinge support, and a boom is hinged below the first crossbar. The camera is installed at the lower end of the boom. A pulley is also provided above the first hinge support, and the winch is connected to the first crossbar by a wire rope passing over the pulley.

[0007] In a preferred embodiment, the wire rope is connected to the end of the first crossbar away from the first hinge support, and the boom is located at the left end of the wire rope connection point.

[0008] In a preferred embodiment, a second hinge support is provided below the first hinge support and fixed to the support leg. A second crossbar is hinged to the second hinge support, and the end of the second crossbar away from the second hinge support is hinged to the lifting rod. The support leg, the first crossbar, the lifting rod, and the second crossbar form a four-bar linkage mechanism.

[0009] The beneficial effects of this utility model are as follows: By installing cameras on the outriggers of the track machine and electrically connecting the cameras to the display screen in the background, the staff can directly observe whether the locks of the containers and the railway container flatcars are unlocked in front of the display screen. This eliminates the need for staff to go to the site to observe whether they are unlocked, thus avoiding certain dangers. Furthermore, by forming a cantilever structure with a winch, a first crossbar, and a boom, the winch can move the camera set below the boom to the space between the two containers via a wire rope. This means that one camera can observe whether at least two containers are unlocked, thereby saving costs in the overall project. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0016] Example 1:

[0017] Please see Figure 1-3 As shown, this application provides a technical solution: a rail-mounted gantry crane container unlocking monitoring device, including a camera 12 installed on the support leg 11 facing the container 10 on the side of the rail-mounted crane, a switch 13 electrically connected to the camera 12, a video recorder 14 electrically connected to the switch 13, and a display screen 15 electrically connected to the video recorder 14. The rail-mounted crane, also known as a rail-mounted gantry crane or rail-mounted hoist, is generally a lifting device used in ports for loading, unloading, handling, and stacking containers in container rail transfer yards and large container storage and transportation yards.

[0018] With the above structure, when it is necessary to lift a container, the rail crane can be moved to the corresponding position so that the camera 12 can capture the position of the vehicle lock head. Then the camera 12 starts recording and transmits the video through the switch 13 and the recorder 14 to the display screen 15 in the background. The staff in the background can judge whether the vehicle lock head is unlocked based on the video content on the display screen 15. Then the staff can notify the rail crane operator to lift the container through the walkie-talkie. In this way, the staff does not need to stand on the side of the container 10 to take pictures and direct the rail crane operator to lift the container, thus avoiding unknown risks.

[0019] In a preferred embodiment, a first hinge support 21 and a winch 22 are provided on the support leg 11 facing the container 10 of the track machine. A first crossbar 23 is provided on the first hinge support 21, and a boom 24 is hinged below the first crossbar 23. The camera 12 is installed at the lower end of the boom 24. A pulley 25 is provided above the first hinge support 21. The winch 22 is connected to the first crossbar 23 by a wire rope 26 passing around the pulley 25.

[0020] Using the above structure, the first crossbar 23, winch 22, and wire rope are connected to form a cantilever mechanism. When the winch releases the wire rope 26, the first crossbar 23 rotates around the first hinge support 21, simultaneously causing the boom 24 to extend to the right. This allows the camera 12 to be moved to the middle of the two containers 10, ensuring that the camera 12 can capture the lock positions of both containers 10. This means that one camera 12 can observe the locks of at least two containers 10, reducing the total number of cameras 12 and achieving cost savings. The camera 12 can be a wide-angle camera, such as a 360-degree wide-angle dome camera.

[0021] When the winch 22 tightens the wire rope 26, the wire rope 26 pulls the first crossbar 23 to rotate to the left around the first hinge support 21. The boom 24 remains downward under its own weight, which can retract the camera 12 to the side close to the outrigger 11. This can prevent the first crossbar 23 from affecting the train passage on the route of the container 10.

[0022] In a preferred embodiment, the wire rope 26 is connected to the end of the first crossbar 23 away from the first hinge support 21, and the boom 24 is located at the left end of the connection point of the wire rope 26.

[0023] With the above structure, the lever arm of the tension of the wire rope at the connection point of the first crossbar 23 to the first hinge support 21 is greater than the lever arm of the weight of the boom 24 to the first hinge support 21. According to the formula of force and lever arm, the winch 22 can pull up the boom 24 with a smaller force.

[0024] Example 2

[0025] Further explanation in conjunction with Example 1;

[0026] This embodiment is a further optimized design based on Embodiment 1. Repeated content will not be described here; only the differences from Embodiment 1 will be described. These differences are as follows:

[0027] In a preferred embodiment, a second hinge support 31 is provided below the first hinge support 21 and fixed on the support leg 11. A second crossbar 32 is hinged to the second hinge support 31. The end of the second crossbar 32 away from the second hinge support 31 is hinged to the hanger 24. The support leg 11, the first crossbar 23, the hanger 24, and the second crossbar 32 form a four-bar linkage mechanism.

[0028] Using the above structure, the four-bar linkage is more stable than the cantilever structure, so the boom 24 is not easy to shake and can be kept in a stable vertical position, thereby reducing the shaking of the camera 12 and enhancing the video shooting effect of the camera 12.

[0029] Since the relative positions of the first hinge support 21 and the second hinge support 31 are fixed, they can also be considered as a connecting rod, which is consistent with the function of the support leg 11 as a connecting rod.

[0030] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
