Description

Technical Field

[0001] The utility model relates to a suspension conveyor positioning structure, belonging to the technical field of continuous conveying equipment. Background Art

[0002] Catenary transport is currently widely used in the industrial field, from logistics transportation to automated production. Catenary transport has many advantages, such as: the catenary has good spatiality and a wide range of applications. It can run continuously in drying areas, harmful gas areas, spray booths, pre-treatment of paint, freezers, aerial storage and other fields to complete the production and transportation process that is difficult to operate manually, thereby improving the working conditions of workers and increasing the output and quality of products. At the same time, the catenary also has the characteristics of low energy consumption, low maintenance costs, durability, low noise, and easy operation.

[0003] The structure of the suspension conveyor is mainly composed of traction chain, slide, hanger, overhead track, drive device, tensioning device, etc. The current suspension chain transportation equipment still has some shortcomings. When the traction chain, slide and hanger stop running, the hanger and the workpiece on the hanger will inevitably shake, making it difficult to stop quickly and accurately at the specified position, which will affect the precise operation of subsequent equipment. For example, the shaking workpiece will have uneven thickness during the spraying process, which will have an adverse effect on the overall production.

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

[0005] In view of the deficiencies in the background technology, the utility model provides a suspension conveyor positioning structure, which can make the hanger and the workpiece on the hanger stop quickly and accurately at the specified position, avoiding the problem of affecting the precise operation of subsequent equipment due to shaking.

[0010] Furthermore, the catenary hanger is installed at the bottom of the slide, the top of the slide is connected to the catenary track, and the slide is installed inside the catenary.

[0011] Furthermore, the length direction of the crossbeam is perpendicular to the length direction of the catenary track, and the crossbeam is fixed.

[0012] Furthermore, the output shaft of the motor is arranged downward in the vertical direction, and the output shaft of the motor passes through the crossbeam.
