Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically a real-time monitoring device for the gantry crane's walking mechanism. Background Technology

[0002] A gantry crane, also known as a portal frame crane, is a type of boom crane whose bridge is supported on ground rails or a foundation by outriggers on both sides. It runs along ground rails, allowing railway vehicles or other ground vehicles to pass underneath. It is a type of boom crane with a rotatable lifting device mounted on a portal frame. The four legs of the portal frame form four "portals" for railway vehicles and other vehicles to pass through.

[0003] The gantry crane moves using a traveling mechanism. To monitor the mechanism's status during movement, cameras are typically installed at fixed points on it. Existing technology, such as patent number CN216345292U, discloses a real-time monitoring device for a gantry crane's traveling mechanism. This device uses a moving mechanism to drive the monitoring camera back and forth, increasing the monitoring range; a height adjustment mechanism to adjust the camera's height for monitoring at different heights; a rotating mechanism to rotate the camera for omnidirectional monitoring; and an installation mechanism for quick installation and removal of the camera, increasing monitoring efficiency and enriching the device's functionality. However, in actual use, the gantry crane is not always operational. When the crane is stopped, the camera also stops working. Sometimes, the crane needs to be shut down for extended periods, leaving the camera exposed, which can lead to dust accumulation and corrosion from airborne pollutants. Therefore, those skilled in the art have proposed a real-time monitoring device for a gantry crane's traveling mechanism to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a real-time monitoring device for a gantry crane traveling mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A real-time monitoring device for a gantry crane's traveling mechanism includes a storage box and a mounting frame. Two threaded rods are rotatably mounted on the side of the mounting frame near the storage box, symmetrically arranged on the mounting frame. Each threaded rod is threadedly connected to a threaded cylinder, which is fixedly connected to the mounting frame. The mounting frame has a storage cavity, and a rotating shaft penetrating the storage box is rotatably mounted within the storage cavity. A rotating cylinder, conforming to the inner wall of the storage cavity, is mounted on the rotating shaft. An opening is provided on the rotating cylinder, and a camera is installed inside the rotating cylinder. The device also includes:

[0007] A drive mechanism, which is disposed within the mounting bracket, is used to drive the threaded rod to rotate;

[0008] A rotating mechanism is disposed between the rotating shaft and the mounting bracket, and is used to drive the rotating shaft to rotate.

[0009] As a further embodiment of this utility model: the rotating mechanism includes side frames installed on both sides of the storage box, a winding roller is installed at one end of the rotating shaft that passes through the side frame, a connecting rope is wound on the winding roller, the connecting rope passes through the side frame and connects to the mounting frame, and a torsion spring is provided on the rotating shaft that connects to the winding roller and the inner wall of the side frame.

[0010] As a further improvement of this utility model: two symmetrically distributed guide wheels are rotatably mounted inside the side frame.

[0011] As a further embodiment of this utility model: the driving mechanism includes a drive wheel mounted on one end of a threaded rod that passes through the mounting bracket, the two drive wheels being connected by a synchronous belt drive, and a motor connected to one of the threaded rods being mounted on the mounting bracket.

[0012] As a further improvement of this utility model: a first protective folding tube for wrapping the connecting rope is provided between the side frame and the mounting frame.

[0013] As a further improvement of this utility model: a second protective folding tube is provided between the side frame and the mounting frame to wrap the threaded rod and the threaded cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model connects the mounting bracket to the gantry crane, and the camera inside the rotating drum monitors the traveling mechanism of the gantry crane through the opening, making it convenient to understand the status of the traveling mechanism. When the gantry crane stops, the drive mechanism drives the threaded rod to rotate, causing the threaded drum to rise. During this process, the corresponding rotating mechanism drives the rotating shaft to rotate, causing the rotating drum to rotate in the storage cavity. Thus, the opening of the rotating drum is sealed by the storage box, preventing the camera inside the rotating drum from contacting the outside air. This avoids the problem of the camera being exposed to the outside for a long time, which can easily lead to dust accumulation and corrosion due to contact with pollutants in the air.

Detailed Implementation

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figure 1-Figure 5 A real-time monitoring device for a gantry crane's traveling mechanism includes a storage box 1 and a mounting frame 2. Two threaded rods 3 are rotatably mounted on the side of the mounting frame 2 closest to the storage box 1, symmetrically arranged on the mounting frame 2. The threaded rods 3 are threadedly connected to a threaded cylinder 4, which is fixedly connected to the mounting frame 2. A storage cavity 8 is formed within the mounting frame 2. A rotating shaft 9, penetrating the storage box 1, is rotatably mounted within the storage cavity 8. A rotating cylinder 10, conforming to the inner wall of the storage cavity 8, is mounted on the rotating shaft 9. An opening 11 is formed on the rotating cylinder 10, and a camera 12 is installed inside the rotating cylinder 10. The device also includes:

[0023] A drive mechanism is provided inside the mounting bracket 2 for driving the threaded rod 3 to rotate.

[0024] A rotating mechanism is provided between the rotating shaft 9 and the mounting bracket 2, and is used to drive the rotating shaft 9 to rotate.

[0025] By connecting the mounting bracket 2 to the door operator, the camera 12 inside the rotating drum 10 monitors the door operator's walking mechanism through the opening 11, making it easy to understand the status of the walking mechanism. When the door operator stops, the drive mechanism drives the threaded rod 3 to rotate, causing the threaded drum 4 to rise. During this process, the corresponding rotating mechanism drives the rotating shaft 9 to rotate, causing the rotating drum 10 to rotate within the storage cavity 8. The storage box 1 then seals the opening 11 of the rotating drum 10, preventing the camera 12 inside the rotating drum 10 from contacting the outside air. This avoids the problem of the camera 12 being exposed to the outside for a long time, which can easily lead to dust accumulation and corrosion due to contact with air pollutants.

[0026] In one embodiment, the rotating mechanism includes side frames 13 installed on both sides of the storage box 1. A winding roller 14 is installed at one end of the rotating shaft 9 that passes through the side frame 13. A connecting rope 15 is wound on the winding roller 14. The connecting rope 15 passes through the side frame 13 and connects to the mounting frame 2. A torsion spring 17 is provided on the rotating shaft 9 and connects to the winding roller 14 and the inner wall of the side frame 13.

[0027] When camera 12 is needed to monitor the gantry crane's walking mechanism, the drive mechanism drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 causes the mounting frame 2 to descend. During this descent, the connecting rope 15 causes the winding roller 14 to rotate, which in turn drives the rotating shaft 9 to rotate, causing the rotating drum 10 to rotate within the receiving cavity 8. This continues until the opening 11 of the rotating drum 10 rotates to a downward position. At this point, the camera 12 inside the rotating drum 10 opens and can monitor the gantry crane's walking mechanism. When the gantry crane stops, the drive mechanism drives the threaded rod 3 to rotate in the opposite direction, causing the threaded drum 4 to rise, thus allowing the mounting frame 2 to descend. It also rises, and during this process, under the action of the torsion spring 17, the winding roller 14 reverses and winds the connecting rope 15, causing the rotating shaft 9 to reverse, thereby causing the rotating drum 10 to reset. The opening 11 of the rotating drum 10 is sealed by the storage box 1, so that the camera 12 inside the rotating drum 10 does not come into contact with the outside air, avoiding the problem that the camera 12 is easily exposed to the outside for a long time, which can easily lead to the camera 12 getting dusty and contacting pollutants in the air, causing the camera 12 to be corroded. In addition, the lifting and lowering of the threaded cylinder 4 can also drive the mounting bracket 2 to lift and lower, thereby adjusting the monitoring height of the camera 12 inside the rotating drum 10, resulting in better performance.

[0028] In one embodiment, two symmetrically distributed guide wheels 16 are rotatably installed inside the side frame 13 to guide the connecting rope 15.

[0029] In one embodiment, the drive mechanism includes a drive wheel 5 mounted on one end of a threaded rod 3 that passes through the mounting bracket 2. The two drive wheels 5 are connected by a synchronous belt 6. A motor 7 connected to one of the threaded rods 3 is mounted on the mounting bracket 2. A protective cover can be provided on the outside of the motor 7 for protection.

[0030] When camera 12 is needed, motor 7 is started by an external controller. Motor 7 drives one of the threaded rods 3 to rotate, and then drives the other threaded rod 3 to rotate through drive wheel 5 and synchronous belt 6. This causes the two threaded cylinders 4 to descend synchronously, moving the mounting bracket 2 downward. This, in conjunction with the rotating mechanism, causes the rotating drum 10 to rotate, thus exposing camera 12 inside the rotating drum 10. When camera 12 needs to be retracted, simply reverse the threaded rod 3. In addition, the cooperation of threaded cylinders 4 and threaded rods 3 can realize the raising and lowering of the mounting bracket 2, thereby adjusting the monitoring height of camera 12 inside the rotating drum 10, resulting in better performance.

[0031] In one embodiment, a first protective folding tube 18 is provided between the side frame 13 and the mounting frame 2 to wrap the connecting rope 15. The first protective folding tube 18 can protect the connecting rope 15 and prevent it from being exposed to the air and corroding.

[0032] In one embodiment, a second protective folding tube 19 is provided between the side frame 13 and the mounting frame 2 to wrap the threaded rod 3 and the threaded cylinder 4. The second protective folding tube 19 can protect the threaded rod 3 and the threaded cylinder 4, preventing outside air from contacting the threaded rod 3 and the threaded cylinder 4, which could cause the threaded rod 3 and the threaded cylinder 4 to rust and make transmission difficult.

[0033] This utility model connects the mounting bracket 2 to the door operator, while the camera 12 inside the rotating drum 10 monitors the walking mechanism of the door operator through the opening 11, making it easy to understand the status of the walking mechanism. When the door operator stops, the drive mechanism drives the threaded rod 3 to rotate, causing the threaded drum 4 to rise. During this process, the corresponding rotating mechanism drives the rotating shaft 9 to rotate, causing the rotating drum 10 to rotate in the storage cavity 8. Thus, the opening 11 of the rotating drum 10 is sealed by the storage box 1, preventing the camera 12 inside the rotating drum 10 from contacting the outside air. This avoids the problem of the camera 12 being exposed to the outside for a long time, which can easily lead to dust accumulation and corrosion due to contact with pollutants in the air.
