Description

Technical Field

[0001] The utility model belongs to the technical field of gantry cranes, and in particular relates to a traveling mechanism for gantry cranes. Background Art

[0002] Gantry crane, also known as gantry crane, is a variation of bridge crane. In ports, it is mainly used for loading and unloading operations in outdoor cargo yards, material yards and bulk cargo. Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam, which can walk directly on the ground track. Both ends of the main beam can have outward cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards.

[0003] For example, a Chinese patent with publication number CN218931490U discloses a walking mechanism for a gantry crane. The patent sets a rotating wheel, which can block the rotating wheel when the track is twisted, so that the rotating wheel cannot continue to move on the track. At the same time, the moving seat continues to move, so that the rotating wheel can move relative to the moving seat, and then the rotating wheel drives the moving rod to move relative to the moving seat through the fixed block, so that the moving rod can squeeze the control switch, and then the driving component can be controlled by the control switch, so that the moving seat can be controlled to stop and prevent the moving seat from falling off the track, thereby improving safety. By setting a brush and utilizing the contact between the brush and the track, the brush can wipe the track, which can remove debris on the track and prevent the debris from affecting the movement of the moving seat, thereby improving safety.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: the rotation of the drive motor is stopped by squeezing the control switch through the moving rod inside the control cavity, while the bar hole connected to the control cavity is open. Therefore, after long-term use, external dust and dirt may enter the interior of the control cavity through the bar hole, and then may cause the moving rod to be stuck inside the control cavity. At this time, the moving rod cannot squeeze the control switch due to being stuck, and then the drive motor cannot obtain timely feedback from the control switch and stops running, which may affect the use effect of the walking mechanism.

[0006] In view of this, we propose a traveling mechanism for a gantry crane. Utility Model Content

[0007] The purpose of the utility model is to provide a traveling mechanism for a gantry crane to solve the problems raised in the above-mentioned background technology.

[0013] In the present technical solution, the staff uses two driving motors, and the rotation of the driving shafts of the two driving motors will drive the two rollers inside the carrier to rotate, and then the two rollers will roll on the surface of the guide rail. At this time, the rolling of the two rollers will drive the carrier and the gantry crane on top of it to move, and then when the guide rail is deformed, the movement of the carrier will drive the mounting shell inside it to move, and then the conduction block inside the mounting shell will contact the deformed part of the guide rail before the rollers. At this time, the conduction block moves due to the deformation of the guide rail and retracts into the interior of the mounting shell, and then the movement of the conduction block will drive the conduction column to move, and then when the conduction column contacts the pressure sensor, the pressure sensor When the device is subjected to pressure, it will feed back an electrical signal to the control system of the drive motor, and stop the driving shaft of the drive motor from rotating, thereby stopping the moving carrier frame and gantry crane from moving, thereby preventing the deformation of the guide rail from causing the carrier frame and gantry crane to derail. In this process, when the conduction block retracts into the interior of the mounting shell, the rebound force of the second spring will push the sealing plate to move, and then under the action of the rebound force of the second spring, the sealing plate will always adhere to the surface of the sealing block, thereby preventing external dust and dirt from entering the interior of the mounting shell through the gap between the conduction block and the sealing block, thereby preventing external dust and dirt from entering the interior of the mounting shell and causing the conduction block to get stuck and affecting its use.

[0017] In the above technical solution, further, the second cleaning component includes:

[0018] A plurality of second mounting blocks are respectively fixedly mounted on both sides of the supporting frame, and every two second mounting blocks form a group; a plurality of third mounting grooves are opened on one side of the interior of the second mounting block; a fourth spring is movably sleeved inside the third mounting groove; a third connecting column is slidably connected inside the third mounting groove; a second cleaning block is arranged on one side of the interior of the second mounting block; and one side of the second cleaning block is fixedly mounted to the third connecting column.

[0019] In the present technical solution, when the carrier moves, the rebound force of the fourth spring inside the third mounting groove will push the second cleaning block to move and keep it always in contact with the inner wall of the guide rail. Then, when the carrier moves, the second mounting block and the second cleaning block will move together with it, and then the second cleaning block will clean the dust and dirt on the inner wall of the guide rail, thereby achieving the effect of cleaning the dust and dirt on the inner wall of the guide rail.

[0020] In the above technical solution, further, two auxiliary rollers are rotatably connected to the inner sides of the carrier frame respectively, the outer circumferential walls of the auxiliary rollers and the rollers are fixedly sleeved with pulleys respectively, and the inner parts of the pulleys are movably sleeved with transmission belts.
