[0002] In the comprehensive mining equipment of mines, the scraper conveyor is an important part of the three comprehensive mining machines. In order to meet the market's diverse needs for the appearance and performance of the equipment, the requirements for the body painting process of the scraper conveyor are getting higher and higher. The most important set of the scraper conveyor production line is the middle trough spraying production line, which uses a self-propelled trolley to hang the spray paint for the painting task of the middle trough. The production cycle is designed to be 4 minutes per hang. After research and testing on the middle trough spraying line, it was found that the upper and lower tooling of the equipment could not meet the design capacity requirements. The direct use of bridge cranes and forklifts would interfere with the steel structure of the production line, posing a major safety hazard.
[0003] According to the actual use of the equipment, combined with the characteristics of the middle tank products, the detailed features of the trial process of the coating production line were carefully sorted out, and the middle tank loading and unloading device was independently designed. After optimization, the problem of loading and unloading the middle tank in the coating production line was successfully solved. According to the actual use effect, the loading or unloading process can be completed in 1.5 minutes, far exceeding the design cycle of 4 minutes per hang. Summary of the invention

[0005] In order to solve the above problems, the utility model provides a device for loading and unloading the paint production line of the middle slot of a mining scraper conveyor, which is composed of a spraying workpiece 1, a control system 2, a traveling mechanism 3, a turning platform 4, a hydraulic cylinder 5, a lifting device 6 and a combined hanger 7; the control system 2 is connected to the lifting device 6 to control the translation of the traveling mechanism 3, the rotation of the turning platform 4 and the lifting of the lifting device 6; the traveling mechanism 3 and the turning platform 4 are hinged to each other as a whole; the hydraulic cylinder 5 is respectively hinged to the traveling mechanism 3 and the turning platform 4; the lifting device 6 is connected to the combined hanger 7; the spraying workpiece 1 is placed above the turning platform 4;
[0006] Furthermore, the walking mechanism 3 is composed of a fixed frame, walking wheels and a driving assembly, and can enter and exit the painting line station on the track; the flip platform 4 is welded by a flat plate and a baffle, and the flip angle of the flip platform 4 is adjustable from 0 to 90 degrees through the extension and retraction of the hydraulic cylinder 5;
[0007] Furthermore, the walking mechanism 3 and the turning platform 4 are hinged through an axis connection seat; the hydraulic cylinder 5 is hinged to the walking mechanism 3 and the turning platform 4 through an axis connection seat respectively;
[0008] Furthermore, a support plate is provided on the right side of the fixed frame of the walking mechanism 3 to support the turning platform 4; a limiter is provided on the left side to limit the turning angle of the turning platform 4;
[0009] Furthermore, the combined lifting device (7) can move up and down in the vertical direction.
[0010] The beneficial effect of the utility model is that the electric walking mechanism is used to drive the flip bracket with a hydraulic connecting rod structure to complete the horizontal movement of the workpiece and the switching of the tilt angle direction, and then the workpiece can be transferred outside the range of the spray painting line by using a forklift or a bridge crane, avoiding a large number of tooling production processes, greatly reducing production auxiliary time, and being easy to use and improving production efficiency. It can not only accurately position the parts directly below the spray painting line hanger, but also adjust the dynamic position of the middle slot when it is lifted on the workstation to ensure stable hanging. At the same time, when the workpiece is dropped during the unloading process, the workpiece can be smoothly placed on the platform of the device to ensure the continuous and stable operation of the middle slot spray painting line.
