Description

Technical Field

[0001] The utility model belongs to the technical field of sintering bellows wear-resistant material production equipment, in particular to a conveying device for sintering bellows wear-resistant material. Background Art

[0002] Sintering bellows are an important part of the sintering process in the steel industry. Due to the harsh working conditions in the sintering process, special wear-resistant materials are required to extend their service life and reduce maintenance costs. Existing wear-resistant materials for sintering bellows usually include ceramics, alloys, stainless steel, wear-resistant rubber, coating materials, composite materials, etc. Ceramic materials (such as silicon carbide and aluminum oxide) can effectively protect the bellows from wear due to their excellent wear resistance and high temperature resistance.

[0003] At present, the production process of wear-resistant materials requires the selection of raw materials, crushing, screening, mixing and other processes, and the material movement between the processes is usually completed by conveyors. Most of the existing conveying devices are fixed structures, and they have the following defects during use: First, the existing conveying devices have poor flexibility. When there is a height difference between the feed and discharge ends, the conveying device cannot adjust the angle to complete the conveying process. When the feed and discharge positions are raised or lowered at the same time, the conveyor cannot be used due to poor adaptability; second, after long-term use, the conveyor belt on the existing conveying device will cause uneven distribution of materials on the conveyor belt, which will cause displacement between the conveyor belt and the drive shaft, affecting the normal operation of the conveyor. Utility Model Content

The lifting function of the conveying frame can be realized through the base frame assembly at the bottom.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As shown in the figure, the conveying device of the wear-resistant material of the sintering bellows includes a chassis assembly whose height can be raised and lowered. A conveying frame 11 with one end hinged on the chassis assembly is installed above the chassis assembly, wherein the conveying frame 11 is hinged to the mounting frame 8 fixed on the chassis assembly, and a driving member for adjusting the inclination angle of the conveying frame 11 when working is provided between the conveying frame 11 and the chassis assembly. Conveying shafts 10 are installed at both ends of the conveying frame 11, and conveying belts 12 are wound around the two conveying shafts 10. When the conveying belts 12 are working, the overall height of the conveying frame 11 can be adjusted according to actual needs, and the angle can be adjusted under the action of the driving member at the same time. Among them, the adjustment of the overall height of the conveying frame 11 is mainly suitable for occasions where both ends of the conveying frame 11 need to be raised or lowered, and the purpose is to adjust the overall height of the conveying frame 11, and the angle adjustment is mainly to meet the situation where there is a height difference between the discharge and feed ends of the conveying frame 11. These two adjustment methods can make the conveying device have a more flexible adjustment effect, so that it effectively expands the scope of application.

[0021] The base frame assembly includes a movable base frame 7 and a fixed base frame 1. The fixed base frame 1 is located below the movable base frame 7. There are lifting rods 5 arranged crosswise with each other between the movable base frame 7 and the fixed base frame 1. One end of the lifting rod 5 is hinged to the fixed base frame 1 and the movable base frame 7, and the other end is hinged to a slider 6 slidably arranged below the fixed base frame 1 and the movable base frame 7. When the slider 6 moves along the length direction of the fixed base frame 1, the two crosswise lifting rods 5 can drive the movable base frame 7 to move relative to the fixed base frame 1.

[0022] Guide rails 2 are respectively arranged below the movable base frame 7 and above the fixed base frame 1, and a slider 6 is slidably connected to the guide rails 2. A lifting motor 4 is fixed at one end of the fixed base frame 1, and a screw rod 3 is connected to the axial end of the lifting motor 4. The screw rod 3 passes through the slider 6 on the fixed base frame 1 and is threadedly engaged with the slider 6.

[0023] The overall working process of the base frame assembly is: the lifting motor 4 is used to drive the screw rod 3 to rotate. After the screw rod 3 rotates, the slider 6 close to the side of the fixed base frame 1 can be moved horizontally, so that the cross-intersecting lifting rods 5 can be moved, and then the relative distance between the movable base frame 7 and the fixed base frame 1 is changed, so as to achieve the purpose of adjusting the overall height of the movable base frame 7, and then the effect of adjusting the overall height of the conveyor frame 11 is achieved.

[0024] Moving wheels 9 are installed at both ends of the movable base frame 7. When the distance between the fixed base frame 1 and the movable base frame 7 is the smallest, the moving wheels 9 can contact the ground to facilitate the movement of the conveying device.

[0025] The driving member is a cylinder 13, one end of which is hinged to the surface of the base frame assembly, and the end of the telescopic rod of the cylinder 13 is hinged to the upper conveying frame 11, and the angle of the conveying frame 11 is changed by hydraulic drive.

[0026] The conveying shaft 10 is provided with a tapered portion 15 whose diameter gradually increases from the middle to both ends, and a step portion 14 is provided at the end with the maximum outer diameter close to the tapered portion 15. The inner wall cross-section of the conveying belt 12 is a V-shaped structure, and the shape of the V-shaped structure matches the shape of the tapered portion 15 on the conveying shaft 10. Such a configuration can ensure that the conveying belt 12 is always in the middle position of the conveying shaft 10 during operation, avoiding the problem of displacement of the conveying belt 12 relative to the conveying shaft 10. In addition, the step portions 14 at both ends of the conveying shaft 10 can further enable the conveying belt 12 to be in the middle position of the conveying shaft 10, ensuring the normal transportation of the conveying belt 12, which is conducive to extending its scope of use.

[0027] A driven wheel 16 is installed at the end of one of the conveying shafts 10 , a conveying motor 19 is installed on the conveying frame 11 , a driving wheel 18 is connected to the shaft end of the transmission motor, and the driving wheel 18 and the driven wheel 16 are connected through a conveyor belt 17 .

[0028] The outer surface of the conveyor belt 12 is provided with a plurality of baffles 20 at equal intervals. The baffles 20 can ensure effective conveyance of wear-resistant materials when the conveyor belt 12 is in an inclined state.

[0029] This conveying device for sintered bellows wear-resistant materials is mainly used to solve the problem of inter-process conveying during the production of wear-resistant materials. Since the production of wear-resistant materials has complex processes and diverse processing equipment, the traditional fixed conveying device can no longer meet the conventional conveying needs. The conveying device in this embodiment can not only meet the lifting and lowering of the overall height of the conveying frame 11, but also meet the changes in the inclination angle. At the same time, the conveying shaft 10 at both ends is designed to have a tapered portion 15 structure, which, together with the V-shaped bottom surface of the conveyor belt 12, can ensure that the conveyor belt 12 can work stably for a long time, and has the advantages of a wide range of applications and flexible and diverse adjustments.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
