Description

Technical Field

[0001] The utility model relates to the technical field of supporting legs on material loading equipment, in particular to a mobile supporting leg driven by a motor. Background Art

[0002] With the rapid development of logistics in my country, three-dimensional conveying warehouses have been adopted in many industries for the circulation of materials. New requirements are constantly being put forward for the loading of materials, which can no longer meet the existing loading speed and indoor application scenarios. The existing loading system places the stacked materials on the loading platform by forklifts. The loading platform is fixed and docked with the loading platform by reversing the container truck. However, when short-distance adjustment is required, the container truck is more troublesome to reverse and adjust the docking. In addition, the short-distance adjustment is more difficult and slow for the truck to drive. At the same time, it increases the difficulty of loading in the factory and outdoors, resulting in reduced loading efficiency in the later stage and a higher risk factor.

[0003] Based on the above background, a motor-driven mobile support leg is proposed to solve the problem that the loading platform can be adjusted to dock with trucks over a short distance. Utility Model Content

DETAILED DESCRIPTION

[0026] The following describes the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as no conflict arises, the various embodiments of the present invention and the various features in each embodiment can be combined with each other, and the resulting technical solutions are all within the scope of protection of the present invention.

[0027] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.

[0028] See also Figure 1-3The utility model provides a motor-driven mobile leg, including: a track 1, a roller 2, a rotating rod 3, a leg 4, a mounting seat 5, a transition sprocket 6, a chain 7, a driving sprocket 8, a motor 9, and a tensioning pulley 10. The roller 2 is rotatably arranged on the track 1, the roller 2 is mounted on the lower side of the leg 4, the rotating rod 3 is connected to the roller 2, the mounting seat 5 is movably mounted on the track 1, the transition sprocket 6 is located in the mounting seat 5, the driving sprocket 8 is mounted on the motor 9, and the motor 9 is located on the mounting seat 5. The chain 7 is wound into a closed loop through the driving sprocket 8, the transition sprocket 6, and the rotating rod 3. The tensioning pulley 10 is mounted on one side of the leg 4 and presses and bends the chain 7.

[0029] When in use, the mobile support leg is installed under the loading platform. When the loading platform needs to adjust the short distance to dock with the truck, the motor 9 is started to drive the sprocket 8 to rotate, and the chain 7 is driven to operate under the action of the transition sprocket 6 and the rotating rod 3. During operation, the rotating rod 3 is rotated, so that the roller 2 moves on the track 1, thereby driving the support leg 4 to walk on the track 1, thereby enabling the entire loading platform equipment to move on the track 1, which has the function of realizing the short-distance movement of the loading platform to dock with the truck. Among them, the tightness of the chain is adjusted by the tensioning wheel 10, so that the chain will not fall off the driving sprocket 8, the transition sprocket 6 and the rotating rod 3, thereby realizing smooth control of the left and right movement of the support leg 4.

[0030] The motor drives the sprocket to drive the roller to move on the guide rail. The chain is adjusted in tension by the tension wheel assembly. The movement position of the outrigger is controlled by the distance sensor and the proximity switch, thereby driving the movement of the entire equipment. At the same time, the track side panels are designed with limited anti-collision blocks to prevent the outrigger and equipment from falling off the track due to operational errors during the debugging process, thereby damaging the structure.

[0031] According to some embodiments of the present application, optionally, a plurality of fixing seats 11 are provided on the lower side of the track 1, which can achieve a more secure installation of the track 1.

[0032] According to some embodiments of the present application, a proximity switch 12 is optionally installed on the track 1, and a distance sensor 13 is installed on the lower side of the leg 4. The distance and position of the leg 4 are controlled by the proximity switch 12 and the distance sensor 13. This has the function of realizing real-time intelligent monitoring and control of the movement distance and position of the leg 4.

[0033] According to some embodiments of the present application, a collision avoidance block 14 is optionally installed on one side of the track 1, and a stopper 15 is provided on the lower side of the leg 4 at the same height as the collision avoidance block 14. When the leg 4 moves, the collision avoidance block 14 blocks the stopper 15, so that the leg 4 does not fall off the track 1, thereby preventing the leg 4 and the loading platform equipment from falling off the track 1 due to operational errors, which could cause damage to the equipment.

[0034] According to some embodiments of the present application, a transmission sprocket is optionally mounted on the rotating rod 3, and the transmission sprocket is engaged with the chain 7. The chain 7 drives the transmission sprocket to rotate, so that the rotating rod 3 can rotate the roller 2 more smoothly, effectively preventing the chain 7 from slipping when rotating on the rotating rod 3.
