Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, and in particular to a special hanging idler set for the tail car of a stacker. Background Technology

[0002] Stackers use a conveyor structure to transfer materials from the source to the stacking point. Taking a cantilever stacker as an example, the material arrives at the stacker's inlet via a belt conveyor, and then is transported to the end of the cantilever via a cantilever belt conveyor. The cantilever can rotate and tilt, thereby evenly stacking the material in different positions, achieving layered and zoned stacking, and improving space utilization.

[0003] The stacker tail car's suspended idler support is located at the very end of the stacker tail car, serving as a transition point from the ground conveyor belt to the stacker tail car. When the ground conveyor belt is running, material climbs uphill from the rear of the stacker tail car and enters the tail car. At this time, the conveyor belt at the very end of the tail car is in an unfolded flat state. During material discharge and high flow rates along the line, material and mud / water are easily overflowed onto both sides of the tail idler support, accumulating in the angle between the suspended idler support and the idler. This causes the idler to jam during operation. The accumulated material in the angle between the suspended idler support and the idler cannot be cleaned immediately. The existing solution is to clean it during machine change intervals to ensure the normal use of the idler. However, even after cleaning, mud / water continues to accumulate during high flow rates, causing the accumulated material to jam the idler and affecting the normal use of the structure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special hanging idler roller group for the tail car of the stacker, which aims to improve the problem in the prior art where mud and water continue to accumulate when there is a large flow, causing the idler roller to be blocked by accumulated material, thus affecting normal use.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a special hanging idler roller assembly for the tail car of a stacker, including an idler roller bracket. Support plates are fixedly connected to the top front and rear sides of the inner wall of the idler roller bracket. An idler roller groove is formed on the top of the support plate. Bolts are threadedly connected to the left and right sides of the top wall of the support plate. A protective plate is threadedly connected to the center of each bolt. An arc-shaped groove is formed on the adjacent side of each of the two protective plates. A locking groove is formed on the opposite side of the top wall of each of the two protective plates. A connecting plate is fixedly connected to the opposite side of each of the two support plates. A locking groove is formed in the center of the top wall of the connecting plate. The bottom of the protective plate engages with the locking groove. Locking plates are rotatably connected to the top left and right sides of the connecting plate. The bottom of the locking plates engages with the locking groove. A reinforcing mechanism is provided on the inner top wall of the protective plate to improve its service life.

[0006] As a further description of the above technical solution: The reinforcing mechanism includes two pressure-resistant plates. The bottom walls of the two pressure-resistant plates are respectively fixedly connected to the inner bottom wall of the corresponding protective plate. A reinforcing layer is fixedly connected to the top wall of the pressure-resistant plate. Multiple reinforcing grids are fixedly connected to the front side of the inner wall of the reinforcing layer. Multiple connecting grids are fixedly connected to the right side of the inner wall of the reinforcing layer. A buffer plate is fixedly connected to the top wall of the reinforcing layer. Multiple holes are opened in the top wall of the buffer plate.

[0007] As a further description of the above technical solution: The reinforcing mechanism also includes two protective layers, the bottom walls of which are respectively fixedly connected to the top of the corresponding buffer plate.

[0008] As a further description of the above technical solution: The outer walls of the multiple reinforcing grids and the multiple connecting grids are fixedly connected and form a square grid structure.

[0009] As a further description of the above technical solution: Each of the bolts has a rubber ring fixedly connected to its upper middle part, and each of the rubber rings has a cylindrical design.

[0010] As a further description of the above technical solution: The top walls of both pressure plates are provided with multiple semi-circular grooves, and the multiple semi-circular grooves are provided at equal intervals.

[0011] As a further description of the above technical solution: A prestressed plate is fixedly connected to the bottom of the inner wall of the roller bracket, and the outer wall of the prestressed plate is designed to be smooth.

[0012] As a further description of the above technical solution: The roller bracket has grooves on both the left and right sides, and the top walls of the two connecting plates each have two mounting slots on the side furthest from each other.

[0013] This utility model has the following beneficial effects: In this utility model, the guard plate can be locked to the top of the support plate 3 by the installation of bolts. Then, the bottom of the guard plate can be fixed by the flipping of the locking plate to form an inclined surface. When the material or mud overflows to the outside of the idler roller bracket, it can slide down quickly through its inclined surface, which is not easy to cause the accumulation of material. At the same time, it increases the stability of the connecting idler roller bracket base, disperses the force on the connecting plate, and avoids the situation of material accumulation blocking the idler roller.

[0014] In this invention, the connection of the reinforcing layer enables the multiple reinforcing grids and multiple connecting grids inside to form a reinforcing structure, thereby improving the internal strength of the protective plate. At the same time, the connection between the buffer plate and the pressure-resistant plate increases the stability of the protective plate and extends its service life. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a special hanging idler roller assembly for the tail car of a stacker, including an idler roller bracket 1. Support plates 3 are fixedly connected to the front and rear sides of the top inner wall of the idler roller bracket 1. The top of the support plate 3 has an idler roller groove 4, allowing for the installation and connection of the idler roller. Bolts 5 are threaded to the left and right sides of the top wall of the support plate 3, and a protective plate 6 is threaded to the center of each bolt 5. The threaded connection between the protective plate 6 and the bolts 5 allows for initial installation and fixation. An arc-shaped groove 7 is formed on the adjacent side of each of the two protective plates 6, and an arc-shaped groove 7 is formed on the side of the top wall of each of the two protective plates 6 that is furthest apart. There is a locking groove 8. The two support plates 3 are fixedly connected to the opposite sides of each other with a connecting plate 9. The arc groove 7 can be used to adapt to the connection and installation of the idler roller. The connecting plate 9 can connect and support the guard plate 6. The top wall of the connecting plate 9 has a locking groove 10 in the middle. The bottom of the guard plate 6 is locked with the locking groove 10. The top left and right sides of the connecting plate 9 are rotatably connected with locking plates 11, so that the bottom of the guard plate 6 can be locked under the connection of the locking plates 11. The bottom of the locking plate 11 is locked with the locking groove 8. The inner top wall of the guard plate 6 is provided with a reinforcing mechanism 2. The reinforcing mechanism 2 is used to improve the service life of the guard plate 6. Specifically, the guard plate 6 is engaged with the top of the connecting plate 9, thus achieving initial installation. With the rotation of the bolt 5, the guard plate 6 is locked with the top of the support plate 3. By flipping the locking plate 11, the locking groove 8 on one side of the guard plate 6 is fixed and engaged, ensuring the stable connection of the guard plate 6. As the guard plate 6 and the connecting plate 9 form an inclined surface, when materials or mud overflow to the outside of the idler roller bracket 1, they can quickly slide down to the bottom with the help of the inclined surface, thereby quickly discharging them and effectively preventing the accumulation of materials and mud. In addition, it also improves the stability of the base of the connecting idler roller bracket 1, disperses the force borne by the connecting plate 9, and ultimately avoids the situation of material accumulation blocking the idler roller.

[0019] Reference Figure 1 , Figure 3 and Figure 5 The reinforcing mechanism 2 includes two pressure-resistant plates 201. The bottom walls of the two pressure-resistant plates 201 are fixedly connected to the inner bottom walls of the corresponding protective plates 6. The pressure-resistant plates 201 improve the pressure resistance of the bottom of the protective plates 6. The top wall of the pressure-resistant plate 201 is fixedly connected to a reinforcing layer 203. Multiple reinforcing grids 204 are fixedly connected to the front side of the inner wall of the reinforcing layer 203. The overall strength of the protective plates 6 is improved by the connection between the reinforcing grids 204 and the connecting grids 205. Multiple connecting grids 205 are fixedly connected to the right side of the inner wall of the reinforcing layer 203. A buffer plate 206 is fixedly connected to the top wall of the reinforcing layer 203. The buffer plate 206 disperses the pressure on the top. Multiple holes 207 are opened on the top wall of the buffer plate 206. Specifically, by fixing the pressure-resistant plate 201, the pressure resistance of the bottom of the protective plate 6 can be improved. Subsequently, with the connection of the reinforcing layer 203, the multiple reinforcing grids 204 and multiple connecting grids 205 inside the protective plate 6 can be tightly combined to form a grid structure, which enhances the overall strength inside the protective plate 6. Moreover, with the assistance of the buffer plate 206, the pressure on the top of the protective plate 6 can be effectively dispersed and absorbed. In this way, the service life of the protective plate 6 is extended when facing pressure and impact.

[0020] Reference Figure 1 , Figure 4 and Figure 5 The reinforcing mechanism 2 also includes two protective layers 208, the bottom walls of which are fixedly connected to the top of the corresponding buffer plates 206; the outer walls of multiple reinforcing grids 204 and multiple connecting grids 205 are fixedly connected and form a square grid structure; rubber rings 12 are fixedly connected to the upper middle part of multiple bolts 5, and the multiple rubber rings 12 are all designed in a columnar shape. Specifically, the protective layer 208 improves the overall protection of the reinforcing mechanism 2, the square grid structure formed by multiple reinforcing grids 204 and multiple connecting grids 205 improves the toughness of the reinforcing layer 203, and the rubber ring 12 reduces the rotational damage of the bolts 5 to the top wall of the guard plate 6.

[0021] Reference Figure 1 , Figure 2 and Figure 5 The top walls of the two pressure plates 201 are provided with multiple semi-circular grooves 202, and the multiple semi-circular grooves 202 are provided at equal intervals; the bottom of the inner wall of the roller bracket 1 is fixedly connected to a prestressed plate 14, and the outer wall of the prestressed plate 14 is designed to be smooth; the left and right sides of the roller bracket 1 are provided with grooves 15, and the top walls of the two connecting plates 9 are provided with two mounting grooves 13 on the side away from each other. Specifically, the opening of the semi-circular groove 202 improves the toughness of the pressure plate 201, the connection of the prestressed plate 14 improves the strength of the middle part of the bottom wall of the roller bracket 1, and the installation groove 13 enables the roller bracket 1 to be connected and installed.

[0022] Working principle: The guard plate 6 is snapped onto the top of the connecting plate 9 to complete the initial installation. Then, with the rotation of the bolt 5, the guard plate 6 can be locked to the top of the support plate 3. Then, with the flipping of the locking plate 11, it can be fixed and snapped into the locking groove 8 on one side of the guard plate 6, so as to achieve the purpose of fixing the connecting guard plate 6. Then, the guard plate 6 and the connecting plate 9 form an inclined surface. When the material or mud overflows to the outside of the idler roller bracket 1, it can slide down quickly through its inclined surface to complete the discharge purpose, which is not easy to cause material accumulation. At the same time, it improves the stability of the base of the connecting idler roller bracket 1, disperses the force on the connecting plate 9, and ultimately avoids the situation of material accumulation blocking the idler roller. Furthermore, by fixing the pressure-resistant plate 201, the pressure resistance of the bottom of the protective plate 6 is improved. Subsequently, with the connection of the reinforcing layer 203, the multiple reinforcing grids 204 and multiple connecting grids 205 inside can form a grid structure, thereby improving the internal strength of the protective plate 6. Then, with the connection of the buffer plate 206, part of the pressure on the top of the protective plate 6 can be offset, thereby improving the service life of the protective plate 6.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
