[0023] The following combines with the attached drawings to illustrate the detailed implementation manners of the present utility model.

[0024] The present utility model provides a logistics transfer system for a heating furnace, aiming to provide an automated solution for the transfer and feeding of the current metal raw materials of the heating furnace.

[0025] As Figures 1 to 5 shown, the present utility model includes a feeding gantry 1, a ground transfer assembly 2 arranged below one end of the feeding gantry 1, and an overhead crane trolley 3 arranged above the feeding gantry 1. A lifting device is installed on the overhead crane trolley 3.

[0026] Through the above technical solution, the present utility model provides the ground transfer assembly 2 to realize the loading and ground transfer work of the raw materials, and through the feeding gantry 1, the overhead crane trolley 3 and the lifting device, the transfer and feeding work of the raw materials at high positions are realized. The two work in combination and cooperation to realize the unmanned automatic feeding of the raw materials from loading to feeding into the heating furnace.

[0027] In some embodiments, the feeding gantry 1 includes four groups of ground frames 11 arranged on the ground. A gantry frame 12 is arranged along the upper plane of each ground frame 11. The two ends of the gantry frame 12 symmetrically extend outwards along the ground frame 11. A guide rail 14 is arranged along the top side of the gantry frame 12. A plurality of reinforcing ribs 13 are also arranged between the gantry frame 12 and the ground frame 11.

[0028] Through the above technical solution, the feeding gantry 1 for convenient lifting and aerial translation is provided. The gantry frame 12 is arranged above the ground frame 11 and extends outwards on both sides to form a working space, so as to facilitate feeding on one side and feeding the raw materials to the lower furnace mouth on the other side (the heating furnace and the lifting device are not shown in the figure).

[0029] In some embodiments, the ground transfer assembly 2 is arranged perpendicular to the feeding gantry 1. It includes two sets of conveyor lines 21 located on the same straight line and a lifting assembly 22 located between the two sets of conveyor lines 21. Each set of conveyor lines 21 includes a bracket 211 on the ground, and a plurality of conveyor rollers 212 are evenly distributed on the bracket 211. The lifting assembly 22 includes a scissor lift 221. A lifting plate 222 is installed on the upper plane of the scissor lift 221, and the same conveyor rollers 212 are arranged on the lifting plate 222. It also includes a tray 23 placed on the conveyor rollers 212. Particularly, when the scissor lift 221 is at its lowest lifting height, the conveyor rollers 212 on the two sets of conveyor lines 21 and the scissor lift 221 are on the same straight line. The conveyor rollers 212 on each set of conveyor lines 21 are connected by a sprocket chain drive, and the conveyor rollers 212 on the scissor lift 221 are connected by a sprocket chain drive.

[0030] Through the above technical solution, the ground transfer assembly 2 is used for the transfer and transportation of raw materials on the ground. In the normal state, the scissor lift 221 does not operate and is at its lowest point. The conveyor lines 21 on both sides and the lifting plate 222 are at the same horizontal height. At this time, the tray 23 can be transported and moved as the conveyor rollers 212 roll; when the raw materials need to be lifted onto the feeding gantry 1, the tray 23 moves to the middle lifting plate 222 along with the moving rhythm. At this time, the scissor lift 221 operates to lift the lifting plate 222, and the lifting device on the overhead crane trolley 3 cooperates with the lifted lifting plate 222 to lift the hopper on the tray 23.

[0031] In some embodiments, the overhead crane trolley 3 includes a trolley chassis 31, two sets of driven guide wheels 32 and two sets of driving guide wheels 33 installed below the trolley chassis 31. A sprocket and a reducer 35 are coaxially installed on the axle of the driving guide wheel 33. A driving member is installed below the trolley chassis 31, and the driving end of the driving member is connected to the input end of the reducer 35 through a belt drive, and the output end of the reducer 35 is connected to the sprocket through a chain drive.

[0032] Through the above technical solution, in order to improve the load capacity of the overhead crane trolley 3 and the chassis installation foundation, one set of driving wheels and one set of driven wheels are adopted for the trolley power. The driving wheels are driven through the reducer 35 and the motor, optimizing the chassis structure.

[0033] In some embodiments, along the plane direction of the trolley chassis 31, it includes multiple sets of grid-shaped profiles constituting the trolley chassis 31. In the center of the trolley chassis 31, it is composed of two cross beams 36 and vertical beams 37 with a larger spacing, and the lifting device is installed in the center of the trolley chassis 31.

[0034] Through the above technical solution, the chassis 31 of the trolley is optimized. The main framework of the chassis is composed of multiple groups of grille-shaped profiles. In order to provide sufficient installation space for the lifting device and avoid interference during the up-and-down movement, two groups of cross beams 36 and two groups of vertical beams 37 are designed in the center of the chassis 31 of the trolley.

[0035] The working principle of the present utility model: During use, first, the excavator in the field drives to the position of the conveyor line 21 and dumps the raw materials into the hopper on the tray 23. The conveyor line 21 transports the tray 23 in a straight line to the intermediate lifting assembly 22. The scissor lift 221 operates to lift the lifting assembly 22 to a certain height for cooperation with the lifting. At this time, the crane trolley 3 travels along the track to the upper part of the lifting assembly 22, and the lifting device installed on the crane trolley 3 lifts the hopper. The crane trolley 3 travels along the track to the upper part of the heating furnace, and the lifting device lowers the hopper to dump the raw materials. In this way, the cyclic automatic loading and unloading is realized by repeating the above process.
