[0027] Figure 1 is a schematic side view of an embodiment of a idler support assembly according to the present utility model, wherein the idler support is in the working position.

[0028] In this embodiment, the upper idler support assembly is taken as an example; however, those skilled in the art should understand that the idler support assembly of the present invention may also be a lower idler support assembly. By rotating the idler support assemblies in Figure 1 and Figure 2 by 180 degrees respectively, so that the idler support, the mounting member, etc. are located below the intermediate frame, an illustration of an embodiment of the upper idler support assembly can be obtained.

[0029] As can be seen from Figure 1 , the idler support assembly for the belt conveyor may include an idler support 1 and a mounting member 5. The end face of the idler support assembly of the belt conveyor is shown in this figure. In a belt conveyor, there may be two such idler support assemblies on the left and right. The two idler supports support the idlers at both ends respectively, thereby supporting the conveyor belt. In this example, the idler support 1 is located above the intermediate frame 6, and the idler support 1 is an upper idler support. In other embodiments, the idler support 1 may also be located below the intermediate frame 6 and be a lower idler support.

[0030] The idler support assembly is fixed to the intermediate frame of the conveyor through the mounting member 5. The overall view of the entire belt conveyor is not shown in the figure, but those skilled in the art can understand that in the case of the upper idler support, during operation, the load-carrying section of the conveyor belt will be supported by the idlers 7 on the idler support 1 to achieve the conveyance of materials. The idler support 1 in the idler support assembly can be tilted to the right in the figure, and at the same time, the idler support in the idler support assembly installed at the other end of the conveyor can also be tilted to the right in the figure, so that the idler 7 is separated from the conveyor belt, as shown in Figure 2 , and is in a position where it can be disassembled and assembled. In the case of the lower idler support, the idler 7 is located below the intermediate frame 6, and during operation, the idler 7 is used to carry the return section of the conveyor belt.

[0031] Specifically, as shown in the figure, in this embodiment, the idler support 1 is used to hold the idlers 7 of the belt conveyor, and the mounting member 5 is suitable for being fixedly installed on the intermediate frame 6 of the belt conveyor and can be a plate-like member. The idler support 1 can be movably installed on the mounting member 5, so that the idler support 1 can be converted from the vertical working position to the inclined loading and unloading position. In the case of the upper idler support assembly, in the working position, the idler support 1 is vertically upward and can support the idlers 7 to carry the load-carrying section of the conveyor belt of the belt conveyor; in the case of the lower idler support assembly, in the working position, the idler support 1 is vertically downward and can support the idlers 7 to carry the return section of the conveyor belt of the belt conveyor. In the loading and unloading position, the idlers 7 can be loaded or unloaded while the belt conveyor is running for replacement.

[0032] As can be seen from the end face of the idler support assembly in Figure 1 , the ends of the idler support 1 and the mounting member 5 can be square, such as rectangular or oblong, etc. As shown in Figure 1As shown, the first side of the end of the idler support 1 can be pivotally connected to the mounting member 5, and the second side of the end of the idler support 1 can be releasably connected to the mounting member 5. A distance can be maintained between the pivotal position at this end and the connection position at this end, so that when both are fixed, the idler support 1 can be stably held in the vertical working position. When the second side of the end of the idler support 1 is connected to the mounting member 5, the idler support 1 is held in the working position, please refer to Figure 1 ; when the second side of the end of the idler support 1 is released from the mounting member 5, the idler support 1 can pivot between the working position and the loading / unloading position, please refer to Figure 2 .

[0033] In the illustrated example, the second side of the end of the idler support 1 is connected to the mounting member 5 by bolts or a pin 4. By removing the bolts or the pin 4, the idler support 1 and the mounting member 5 can move freely relative to each other at this location. In different embodiments, the bolts or the pin 4 can be replaced by other types of detachable connection methods.

[0034] To facilitate laying down the idler support 1, a handle 3 can be provided at the end of the idler support 1 away from the pivotal connection. The handle 3 can be located at the outer end of the idler support 1, facing the outside of the conveyor, which is convenient for operation and can control the slow rotation of the idler support. As can be seen from the figure, in the state of this vertical working position, the handle is located at the second side of the end face of the idler support 1, aligned with the position of the movable connection. The specific form of the handle 3 can be a folding plate, a lug, a grip ring, etc., and can be welded to the end face of the idler support 1. In the case of the upper idler support, the handle can be located on the upper side of the end of the idler support; in the case of the lower idler support, the handle can be located on the lower side of the end of the idler support.

[0035] A limit block 2 can be provided at the outer end of the idler support 1. When the idler support 1 pivots to the loading / unloading position, the limit block 2 abuts against the mounting member 5 for the idler support in the middle to hold the idler support 1 in place. In this way, the idler support 1 is stably located at the loading / unloading position, making the loading / unloading position at a suitable angle. At this time, the position of the idler has been lowered to a distance from the belt surface of the conveyor belt greater than the diameter of the idler, and the idler 7 can be replaced easily and smoothly. As shown in the figure, in this example, the limit block 2 can have a flat abutting surface for abutting against the top of the mounting member 5. At the working position of the idler support assembly, the abutting surface of the limit block can be inclined; at the loading / unloading position of the idler support assembly, the abutting surface of the limit block is horizontal, suitable for abutting against the mounting member 5. This limiting member can be a raised portion on the end face of the idler support 1.

[0036] In an alternative embodiment, handles and / or limit blocks can be provided at both ends of the idler support, or handles and / or limit blocks can be provided only at one end of the idler support.

[0037] In the illustrated example, the included angle between the idler support 1 in the working position and the loading and unloading position is about 45 degrees, so that when disassembling and assembling the idler 7, it will not be affected by the conveyor belt or the intermediate frame. In an alternative embodiment, the included angle between the idler support 1 in the working position and the loading and unloading position is between 30 degrees and 60 degrees, and the idler 7 can still be conveniently disassembled.

[0038] According to the illustrated embodiment, in the case of the upper idler support assembly, the load-carrying section of the conveyor belt can be supported on the idler 7 and travels in the direction from the left side to the right side in the figure. That is, the idler support 1 rotates from the working position towards the downstream direction of the load-carrying section of the conveyor belt to the loading and unloading position, and the idler support 1 rotates from the loading and unloading position towards the upstream direction of the load-carrying section of the conveyor belt to the working position. In the case of the lower idler support assembly, the return section of the conveyor belt can be supported on the idler 7, and the idler support 1 can rotate from the working position towards the downstream direction of the return section of the conveyor belt to the loading and unloading position, and the idler support 1 rotates from the loading and unloading position towards the upstream direction of the return section of the conveyor belt to the working position.

[0039] Figure 2 For Figure 1 Another schematic side view of the middle idler support assembly, where the idler support is in the loading and unloading position.

[0040] For Figure 1 operating on the idler support assembly in, in the case of the upper idler support assembly, remove the bolt or pin 4 on the handle 3 side, and while pulling the handle 3, slowly rotate the idler support around the pivot connection on the other side until the limit block 2 can contact the mounting member 5. At this time, the idler support 1 is in a position where the idler 7 can be replaced, and the handle 3 can be released to start replacing the new idler. After confirming that the idler 7 has been replaced, the idler support 1 can be returned to Figure 1 the normal working position in.

[0041] In the case of the lower idler support assembly, a locking member can be further provided to lock the lower idler support to the mounting member at the loading and unloading position to prevent the lower idler support from automatically falling back to the working position and affecting the replacement of the lower idler.

[0042] In Figure 2 , the idler support 1 has rotated from Figure 1 the vertical working position such that the idler support 1 is in an inclined loading and unloading position relative to the mounting member 5, where the idler support 1 is exemplarily shown to be inclined at an angle of about 45 degrees with respect to the mounting member 5. At this time, by using the gap between the upper and lower belt surfaces of the conveyor belt, it is suitable for the non-stop loading and unloading of the idler at the idler support 1 to avoid the conveyor being stopped due to the replacement of the idler.

[0043] Furthermore, the present utility model also provides a belt conveyor, which may include a roller support assembly as described in any one of the foregoing embodiments. The roller support assembly may be an upper roller support assembly or a lower roller support assembly. In an alternative embodiment, the roller support assembly may be fixed to the intermediate frame 6 of the belt conveyor by a mounting member 5. In such a belt conveyor, the rollers are installed obliquely, so that the conveyor does not have to be stopped when replacing the rollers, enabling the conveyor to operate efficiently and continuously.

[0044] The technical scope of the present utility model is not limited to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the scope of the present utility model.
