[0016] The technical solution of the utility model is further explained below in conjunction with the accompanying drawings and specific embodiments.

[0017] The utility model provides a lifting and conveying mechanism for a hopper, aiming to provide a solution capable of automatically controlling the multi-axis moving freedom, stroke and opening and closing lifting of the hopper for an existing heating furnace unloading process.

[0018] Specifically, Figures 1 to 2 As shown, the lifting and conveying mechanism for the hopper of the utility model includes a lifting bracket 1, a transverse conveying component 2 is arranged along the length direction of the lifting bracket 1, a plurality of groups of staggered lifting components 3 are installed above the body of the transverse conveying component 2, and a guide component 4 is also arranged between each group of lifting components 3 for relative lifting.

[0019] Through the above technical solution, the lateral conveying assembly 2, the lifting assembly 3, and the guide assembly 4 work together to obtain degrees of freedom along the X-axis and the Z-axis, and can obtain a precise moving stroke along the X-axis in conjunction with the rail-mounted electric trolley 21. Through the lifting assembly 3, the driving motor 32 controls the drum 31 to drive the steel rope retracting and releasing line to obtain a stroke in the Z-axis direction.

[0020] In some embodiments, the lifting bracket 1 includes a group of ground frames 11 arranged on the ground, and two groups of top frames 12 are extended along both ends of the upper part of the ground frame 11, and the cross-section between the ground frame 11 and the top frame 12 is designed as a T-shaped structure.

[0021] Through the above technical solution, the lifting bracket 1 is used to raise the height of the bucket for dumping. Since the lifting of the bucket requires working space, in order to avoid interference, the lifting bracket 1 is designed as a T-shaped structure.

[0022] In some embodiments, the transverse conveying assembly 2 includes a guide rail arranged on a relative top frame 12 and a rail-mounted electric trolley 21 . A lifting base 22 is arranged above the chassis of the rail-mounted electric trolley 21 , and a lifting assembly 3 is installed on the lifting base 22 .

[0023] Through the above technical solution, the electric trolley 21 can be integrated with the lifting assembly 3, thereby simplifying the structure and achieving the effect of integration.

[0024] In some embodiments, the lifting assembly 3 includes two groups of rollers 31 staggeredly installed on the lifting base 22, steel ropes for installation are installed at both ends of each group of rollers 31, and a driving motor 32 for transmission is coaxially arranged on the side of each group of rollers 31, and the steel ropes on the two groups of rollers 31 are staggered with each other along the axial direction of the rollers 31.

[0025] Through the above technical solution, each roller 31 is equipped with a steel rope, and the steel ropes on the two rollers 31 are staggered with each other, on the one hand to avoid interference, and on the other hand to connect different objects, such as one group of outer diameters is used to connect the hopper body 5, and one group of inner diameters is used to connect the opening and closing discharge port on the hopper.

[0026] In some embodiments, the guide assembly 4 includes pulleys arranged on the lower surfaces of the front and rear sides of the lifting bracket 1, and the steel rope is installed on the pulley when the wire is reeled in and out downward.

[0027] Through the above technical solution, the pulley is provided to provide guidance for the steel rope reeling and releasing line and prevent interference with the frame body.

[0028] In some embodiments, the steel rope structure at one end of each set of rollers 31 includes two strands of steel rope formed by interlocking. The interlocking installation of steel rope is an installation method, which is usually used in lifting equipment or hoisting systems. In this installation method, the two ends (or multiple ends) of the steel rope alternately pass through the lifting lugs or rings of the hoisting object to form a cross-interlaced structure, so that the steel rope can maintain a relatively stable balance state during the hoisting process.

[0029] The working principle of this utility model:

[0030] This utility model is used for conveying and lifting the hopper during the unloading process of the heating furnace. Specifically, it is equipped with 8 steel ropes and dual motors for lifting. The rail-mounted electric trolley 21 for aerial operation is stable and safer than general aerial lifting devices, and can be linked with remote control to realize automation and remote operation. When the furnace mouth needs aluminum material, the rail-mounted electric trolley 21 drives to the top of the furnace mouth, and then starts two sets of drive motors 32 respectively. The hoisting steel rope falls, the hopper falls into the bottom of the furnace, the discharge port opens, and the unloading is completed. The hoisting starts to raise the hopper and the cover to the highest position, and the trolley returns for shipment. At this time, only the hopper is hoisted, and the hopper reaches the hopper plate for loading! This logistics trolley is a short-transmission aerial gantry hoisting operation, which cooperates with the intelligent system to achieve unmanned and efficient operation! The trolley is equipped with dual motors and dual drums 31. Eight steel ropes are arranged on the surface of the drum 31 and the ends of the steel ropes are fixed. Moreover, the two steel ropes are mutually reversed to form a pair. When the drum rotates, the two ropes are lifted at the same time. There is one pair at the first end of the drum and four pairs at the second end. Through the pulley, one motor controls four groups of mutually reversed steel ropes to lift smoothly.

[0031] The above description is only used as an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
