Description

Technical Field

[0001] The utility model relates to a mobile loading platform with adjustable angle, belonging to the technical field of mobile loading platforms. Background Art

[0002] In the field of production and logistics, the loading and unloading of goods has always been a labor-intensive process. The mechanization and automation of the loading process has become a research hotspot.

[0003] Existing automatic loaders mainly include two categories: one is a truss-type loader. When loading, the truck is driven under the truss, and the loading is carried out by a loading robot that moves on three axes with the help of a visual system. This loading method is complex, expensive, and inefficient; the other is a push-plate conveyor-type loader. This loading method is to place the loading and conveying mechanism on a lifting platform. When loading, the truck is parked next to the loader, and the loading and conveying mechanism moves up and down with the lifting platform to adjust the height between the conveying mechanism and the bottom of the truck. This loading method is more flexible, inexpensive, and efficient. However, the lifting platform is generally driven by hydraulics to lift the platform, and can only be adjusted up and down in height, but it is not convenient to adjust the rotation angle, and the parking of the truck cannot be accurately docked with the conveying mechanism, resulting in inconvenience in loading.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] A rack is fixed on the lower side of the rear end of the load-bearing platform, a driving motor is fixed on the lower side of the rear end of the supporting chassis, a gear is installed on the rotating shaft of the driving motor, and the gear is meshed with the rack for transmission.

[0009] Furthermore, the rack is designed to be arc-shaped, and the center of the arc coincides with the center of the slewing bearing.

[0011] Furthermore, each of the supporting Titan wheel groups includes a row of Titan wheels arranged in an arc, and the center of the arc coincides with the center of the slewing bearing.

[0012] Furthermore, a radar is provided at the front end of the carrying platform to obtain parking angle information of the truck.

[0013] Furthermore, sprockets are provided at both ends of the carrying platform, and chains are wound around the sprockets at both ends. The sprockets are driven by a conveying motor, and the chains pull the conveying mechanism on the carrying platform to transport the goods.

[0014] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0026] like Figure 1-6 As shown, the utility model provides an angle-adjustable mobile loading platform, a load-bearing platform 1, a supporting frame 2 is provided at the lower end of the load-bearing platform 1, a slewing bearing 8 is provided between the load-bearing platform 1 and the supporting frame 2, when working, the supporting frame 2 is fixedly placed on the ground, a conveying mechanism (not shown in the figure) is placed on the load-bearing platform 1, and the load-bearing platform 1 is rotatably mounted on the upper end of the supporting frame 2 through the slewing bearing 8, and the rotation angle range of the load-bearing platform 1 is ≤5°.

[0027] A rack 5 is fixed to the lower side of the rear end of the carrying platform 1 , a driving motor 7 is fixed to the lower side of the rear end of the supporting chassis 2 , a gear 6 is mounted on the rotating shaft of the driving motor 7 , and the gear 6 is meshed with the rack 5 for transmission.

[0028] The rack 5 is designed to be arc-shaped, and the center of the arc coincides with the center of the slewing bearing 8, so that the rack 5 can mesh well with the gear 6 when the rack 5 and the bearing platform 1 swing.

[0029] The two ends of the supporting frame 2 are respectively provided with end cross beams 3, and a supporting Titan wheel group 4 is rotatably installed on the end cross beams 3. The supporting Titan wheel group 4 includes a row of Titan wheels arranged along the length direction of the end cross beams 3. The supporting Titan wheel groups 4 at both ends of the supporting frame 2 support the two ends of the supporting platform 1. At the same time, the supporting platform 1 can rotate relative to the Titan wheels, making the rotation of the supporting platform 1 more flexible.

[0030] Each of the supporting Titan wheel groups 4 includes a row of Titan wheels arranged in an arc, the center of which coincides with the center of the slewing bearing 8, so that when the supporting platform 1 rotates, its two ends roll along the arc of the Titan wheels, further making the supporting platform 1 rotate more flexibly.

[0031] A radar 11 is provided at the front end of the carrying platform 1. When the truck stops steadily, the parking angle information of the truck is obtained through the radar 11 and the parking angle information of the truck is transmitted to the electronic control system. The electronic control system controls the drive motor 7 to operate and adjust the angle of the carrying platform 1 through the meshing transmission of the gear 6 and the rack 5, so that the conveying mechanism on the carrying platform 1 is consistent with the parking angle of the truck, preparing for subsequent automated loading.

[0032] Sprocket wheels 9 are respectively provided at both ends of the carrying platform 1 , and chains 10 are wound around the sprocket wheels 9 at both ends. The sprocket wheels 9 are driven by a conveying motor 12 , and the chains 10 pull the conveying mechanism on the carrying platform 1 to convey the goods into the carriage.

[0033] The specific working principle of the utility model:

[0034] A conveying mechanism is placed on the load-bearing platform 1. The load-bearing platform 1 is rotatably mounted on the upper end of the support chassis 2 through a slewing bearing 8. A rack 5 is fixed on the lower side of the rear end of the load-bearing platform 1. A gear 6 is installed on the lower side of the rear end of the support chassis 2. The gear 6 is meshed with the rack 5 for transmission. The drive motor 7 drives the gear 6 to rotate and drives the load-bearing platform 1 to rotate. The end crossbeam 3 is rotatably mounted with a supporting Titan wheel set 4. The supporting Titan wheel sets 4 at both ends of the support chassis 2 support the two ends of the load-bearing platform 1. At the same time, the load-bearing platform 1 can rotate relative to the Titan wheel. When the truck stops steadily, the parking angle information of the truck is obtained through the radar 11, and the parking angle information of the truck is transmitted to the electronic control system. The electronic control system controls the drive motor 7 to operate, and adjusts the angle of the load-bearing platform 1 through the meshing transmission of the gear 6 and the rack 5, so that the conveying mechanism on the load-bearing platform 1 is consistent with the parking angle of the truck, and the position of the conveying mechanism is accurately aligned with the carriage, so as to prepare for the subsequent automated loading.
