[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0027] like Figure 1 and Figure 2 As shown, the lining steel plate assembly for the ore unloading chute 100 according to the embodiment of the utility model includes an embedded part 2 and a lining part 3.
[0028] The embedded component 2 includes a plurality of embedded plates 21, which are connected end to end in sequence along the circumference of the chute 100, and the outer peripheral wall of the embedded component 2 is adapted to the chute 100. The lining component 3 includes a plurality of lining plates 31 and a flange 32, wherein the plurality of lining plates 31 are connected end to end in sequence along the circumference of the chute 100, the flange 32 is connected to the upper end of the lining plate 31, and the flange 32 extends in a direction away from the lining plate 31, the outer peripheral wall of the lining component 3 is adapted to the inner peripheral wall of the embedded component 2, and the flange 32 abuts against the upper end of the embedded component 2.
[0029] Specifically, Figure 1 and Figure 2 As shown, multiple embedded plates 21 are connected in sequence to form a hollow structure, and the outer contours formed by the multiple embedded plates 21 cooperate with the inner contours of the chute 100, that is, the embedded component 2 can be directly installed in the chute, and the outer peripheral wall of the embedded plate 21 fits with the inner peripheral wall of the chute 100. Similarly, multiple lining plates 31 are connected in sequence to form a hollow structure, and the lining plate 31 can be installed in the space surrounded by the embedded plates 21, and the outer peripheral wall of the lining plate 31 fits with the inner peripheral wall of the embedded plate 21. The flange 32 is connected to the upper edge of the lining plate 31, and the lining plate 31 cooperates with the embedded plate 21. The flange 32 abuts against the upper end of the embedded component 2 and extends toward the ground near the chute 100, so as to prevent the lining plate 31 from deforming and moving downward after long-term use, thereby ensuring the service life of the lining component 3.
[0030] It is understandable that the lining steel plate assembly for the unloading chute 100 of the utility model embodiment can be provided with the matching embedded parts 2 and lining parts 3 according to the chutes 100 of different shapes and specifications. Among them, after the embedded parts 2 are installed, they are placed under the lining parts 3 and do not directly contact the materials in the chute 100, thereby reducing the possibility of wear and deformation of the lining parts 3.
[0031] That is to say, the use of the lining steel plate assembly of the embodiment of the utility model in the chute 100 for protection can not only provide better protection measures, but also effectively reduce the impact deformation and wear of the wear-resistant steel plate during long-term use, thereby reducing the risk of damage to the concrete structure. Compared with the traditional technology, the replacement of the lining steel plate in the embodiment of the utility model is also more convenient. There is no need to perform flame cutting to remove the damaged wear-resistant steel plate, but directly replace the lining plate 31, which saves time and effort and reduces the difficulty of the replacement process.
[0032] Optionally, among the multiple embedded plates 21, two adjacent embedded plates 21 are connected by welding. Among the multiple lining plates 31, two adjacent lining plates 31 are connected by welding, and the flange 32 is connected to the lining plate 31 by welding. It can be understood that the multiple embedded plates 21 can be connected by welding to ensure the connection strength between the embedded plates 21, and also make the overall corrosion resistance and sealing of the multiple embedded plates 21 better. In addition, the connection by welding is also convenient for the storage and transportation of the embedded plates 21. Similarly. The connection strength between the lining plates 31 is high, the overall corrosion resistance is good, the sealing is good, and it is also convenient for transportation and storage.
[0033] Optionally, multiple embedded plates 21 are integrally formed. Multiple lining plates 31 and flanges 32 are integrally formed. It is understood that the integral forming method can make the material properties of the plate joints more consistent and uniform, thereby increasing the overall strength and rigidity, and the integral forming method can also improve production efficiency and machining speed.
[0034] In other words, the lining steel plate assembly for the ore unloading chute 100 of the embodiment of the utility model is divided into two layers of embedded parts 2 and lining parts 3 as a protective measure for the ore unloading chute 100, which improves the overall wear resistance and can also be replaced promptly and quickly after the lining parts 3 are worn or deformed, thereby ensuring the use efficiency of the ore unloading chute 100. In addition, the lining parts 3 are arranged with flanges 32, so that the lining parts 3 can be stably pressed on the embedded parts 2, which ensures the stability of the lining parts 3 and prevents the lining parts 3 from being deformed.
[0035] In some embodiments, in a direction perpendicular to the depth direction of the chute 100 (eg Figure 1In a plane (in the up-down direction), the flange 32 is annular, and the inner peripheral wall of the flange 32 is connected to the outer peripheral wall surrounded by multiple inner lining plates 31.
[0036] Specifically, Figure 1 and Figure 2 As shown, in a plane orthogonal to the up and down directions (i.e., a horizontal plane), the profile of the flange 32 is a square ring, and the inner peripheral wall of the flange 32 is connected to the upper edge of the inner lining plate 31, so that when the inner lining plate 31 is inserted into the space surrounded by the embedded plate 21, the flange 32 can support and fix the inner lining plate 31, thereby preventing the inner lining plate 31 from sinking to a deeper position in the chute 100 due to its own deformation after long-term use.
[0037] It can be understood that the flange 32 can also serve to block the gap between the embedded plate 21 and the ground of the chute 100 and the gap between the embedded part 2 and the lining part 3, thereby effectively preventing external pollutants such as water vapor and impurities from diffusing into the depths of the gap through the gap, thereby improving the corrosion resistance of the lining steel plate assembly of the embodiment of the utility model.
[0038] In some embodiments, the lining member 3 further includes a lifting ear 33 , which is connected to the flange 32 . There are multiple lifting ears 33 , and the multiple lifting ears 33 are arranged relatively spaced apart in the circumferential direction of the chute 100 .
[0039] It can be understood that the plurality of lifting ears 33 is an even number, two lifting ears 33 form a pair, and the two lifting ears 33 in a pair of lifting ears 33 are symmetrically arranged along the center line of the space surrounded by the inner lining plate 31. When the inner lining member 3 is disassembled, it is avoided that the inner lining plate 31 is subjected to unilateral force or uneven force, thereby facilitating the lifting equipment to lift the inner lining member 3 through the lifting ears 33, thereby improving the lifting safety factor.
[0040] In some embodiments, the embedded part 2 also includes an anchor bar 22, the first end of the anchor bar 22 is connected to the embedded plate 21, the embedded plate 21 is placed in the chute 100, and the second end of the anchor bar 22 is inserted into the side wall of the chute 100. There are multiple anchor bars 22, and the multiple anchor bars 22 are arranged at intervals along the width direction of the embedded plate 21. The anchor bar 22 also includes multiple anchor bar 22 groups, one anchor bar 22 group includes multiple anchor bars 22, and the multiple anchor bar 22 groups are arranged at intervals along the height direction of the embedded plate 21.
[0041] It is understandable that if Figure 1 and Figure 2 As shown, the first end of the anchor bar 22 can be connected to the outer wall of the embedded plate 21 by threaded connection or welding. When the embedded part 2 is placed in the chute 100, the second end of the anchor bar 22 is inserted into the side wall formation of the chute 100, thereby fixing the embedded part 2, and when used for a long time, the anchor bar 22 can also effectively transfer the load, effectively control and prevent the expansion of cracks on the side wall of the chute 100.
[0042] In some embodiments, the anchor bar 22 includes a first section 221, a second section 222 and a third section 223 which are connected in sequence, the first section 221 is connected to the embedded plate 21, an extension direction of the first section 221 and an extension direction of the second section 222 have an angle, and an extension direction of the second section 222 and an extension direction of the third section 223 have an angle.
[0043] It is understandable that if Figure 2 and Figure 3 As shown, since the anchor bar 22 is divided into multiple sections, there is a certain angle between two adjacent sections, so that the anchor bar 22 penetrates into the side wall stratum of the chute 100, further enhancing the anchoring effect. In addition, each section of the anchor bar 22 can also bear a part of the tension. When it is necessary to bear a large tension, each section of the anchor bar 22 can share the tension, thereby improving the overall tensile bearing capacity.
[0044] Preferably, if Figure 3 As shown, the extension direction of the first section 221 is orthogonal to the embedded plate 21. That is, since the side wall of the chute 100 is arranged obliquely and the embedded plate 21 can be adapted to the side wall of the chute 100, the extension direction of the first section 221 is orthogonal to the embedded plate 21, and the anchor bar 22 is inserted into the side wall stratum of the chute 100 at an angle of 90 degrees as a whole. This not only facilitates the installation of the embedded plate 21, but also ensures the anchoring effect of the anchor bar 22.
[0045] Preferably, if Figure 3 As shown, the extension direction of the second section 222 is perpendicular to the extension direction of the first section 221, the extension direction of the third section 223 is perpendicular to the extension direction of the second section 222, and the third section 223 extends in the direction toward the embedded plate 21. In other words, the angles between the multiple sections of anchor bars 22 can enable the various sections of anchor bars 22 to work better together when subjected to force, optimize the force performance, and improve the stability and safety of the structure.
