Description

Technical Field

[0001] The utility model relates to a lifting conveyor, in particular to a lifting conveyor for automobile transportation. Background Art

[0002] A car is a means of transportation, a vehicle driven by power, with four or more wheels and no tracks, mainly used to carry people or goods, to tow vehicles carrying people or goods, etc. When transporting cars, a lifting conveyor is used, which can quickly and efficiently move the car from the ground or one plane to another, especially in multi-storey garages, ship cabins or truck trailers, which can significantly speed up loading and unloading and reduce waiting time.

[0003] At present, when using a lifting conveyor to transport cars, the specific transportation steps are as follows: first drive the car to be transported onto the driving platform of the lifting conveyor, then start the lifting conveyor, and the driving platform rises steadily with the mechanical structure until the car is aligned with the designated placement layer of the multi-layer transport truck, and finally the car is driven from the driving platform into the placement layer of the multi-layer truck to complete the loading. However, the friction transmission method between the belt and the roller used in the traditional lifting conveyor has certain limitations. For example, the installation process of the belt and the roller is relatively complicated, requiring precise alignment and tension adjustment, which increases the installation time and difficulty. In addition, the driving platform carries a large weight, and the belt is prone to slight deformation after long-term use, which will affect the running stability of the belt and even cause biting, that is, abnormal contact between the edge of the belt and the roller occurs, resulting in increased wear. Biting and other types of belt damage will significantly increase subsequent maintenance operations, which not only consumes more manpower and material resources, but may also affect transportation efficiency and production plans.

[0004] Therefore, a lifting conveyor for automobile transportation is particularly needed to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0019] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0020] Embodiment: A lifting conveyor for automobile transportation, see Figure 1-Figure 4 As shown, it includes a connecting plate 1, a column 2, a stabilizing beam 3, a guide wheel 5, a counterweight 4, a servo motor 7, a gear 8, a rack 9, a mounting block 10, a roller 11, a steel cable 12, a lifting frame 13, a crossbeam 14, a lifting platform 15 and a limit strip 16. The bottom of the connecting plate 1 is connected to a plurality of columns 2 distributed in a rectangular direction by welding. The bottom of the column 2 is provided with an anti-sliding block made of rubber material. Stabilizing beams 3 distributed up and down are connected between every two longitudinally aligned columns 2 by welding to increase the stability of the column 2. The stabilizing beams 3 are made of hard metal. A plurality of guide wheels 5 are slidably connected to the column 2 by a slide rail. The guide wheels 5 are rubber-coated wheels. The plurality of guide wheels 5 on the same side are connected to the counterweight 4 by bolts. The counterweight 4 is connected to the servo motor 7 by bolts. The output shaft of the servo motor 7 A gear 8 is connected to the top by welding, a rack 9 is connected to the column 2 by welding, the gear 8 is meshed with the rack 9, the top of the connecting plate 1 is connected to the mounting blocks 10 distributed in the left and right by welding, the mounting blocks 10 are rotatably connected with rollers 11 inside, a steel cable 12 is wound around the roller 11, one end of the steel cable 12 is connected to the counterweight 4, a lifting frame 13 is connected between the multiple guide wheels 5 on the same side by bolts, the other end of the steel cable 12 is connected to the lifting frame 13, a cross beam 14 distributed in the front and back is connected between the two lifting frames 13 by bolts, a lifting platform 15 is connected between the upper parts of the two cross beams 14 by bolts, and two limit strips 16 for limiting the wheels of the vehicle are connected to the rear side of the top of the lifting platform 15 by bolts, and the inclined surfaces of the two limit strips 16 face each other to form a triangular groove.

[0021] First, the operator contacts the truck driver to drive the multi-storey truck to the side of the lifting conveyor, so that the carriage of the multi-storey truck is located directly in front of the lifting platform 15, and then the servo motor 7 is turned on. The output shaft of the servo motor 7 drives the gear 8 to rotate and engage with the rack 9 in a positive manner, so that the gear 8 drives the servo motor 7 and the counterweight 4 to rise. During this process, the steel cable 12 is short on the outside and long on the inside, so that the lifting frame 13, the beam 14 and the lifting platform 15 are lowered under the action of their own weight. When the lifting platform 15 drops to the lowest height, the servo motor 7 is turned off. Then the operator places the ramp on the bottom surface and aligns it with the lifting platform 15, drives the car to be transported onto the lifting platform 15, and embeds the two rear wheels of the car between the two limit bars 16. Then the servo motor 7 is restarted, and the output shaft of the servo motor 7 is controlled to reverse, driving the gear 8 to reverse and engage with the rack 9 in the opposite direction. , and then the gear 8 drives the servo motor 7 and the counterweight 4 to descend. During this process, the steel cable 12 is longer on the outside and shorter on the inside, pulling the lifting frame 13, the crossbeam 14 and the lifting platform 15 to rise. During the rising process, the guide wheel 5 slides along the column 2 to ensure that the lifting platform 15 rises smoothly, and the two limit strips 16 cooperate to limit the two rear wheels of the car to prevent the car from slipping without pulling the handbrake. When the lifting platform 15 rises to a suitable height and aligns the car to the designated placement layer of the multi-layer truck, the servo motor 7 is immediately turned off, and then the car is driven from the driving platform to the placement layer of the multi-layer truck to complete the loading. After the loading is completed, the servo motor 7 is turned on again, and the output shaft of the servo motor 7 is controlled to rotate forward to make the lifting platform 15 descend. When the lifting platform 15 descends to the lowest height, the servo motor 7 is turned off. When it is necessary to continue to transport the car, the above steps can be repeated.
