Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a retractable belt conveyor tail receiving section idler frame and idler assembly, and a conveyor. Background Technology

[0002] In fully mechanized coal mining operations, the tail receiving point of the telescopic belt conveyor will move. As the fully mechanized mining face advances, the length of the entire conveyor will continuously shorten. The material is unloaded onto the belt at the tail of the telescopic belt conveyor. The unloading force of the belt acts on the idlers on the anti-drop idler frame of the receiving section. The idler support groove on the idler frame at the tail of the telescopic belt conveyor is U-shaped. When the idler on the idler frame at the receiving point is impacted by the unloading force of the material, the idler shaft may come out of the idler support groove. Summary of the Invention

[0003] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a retractable belt conveyor tail receiving section idler frame.

[0004] A retractable belt conveyor tail receiving section idler frame includes a main frame and supports symmetrically arranged on both sides of the main frame; the upper end of the support is provided with a groove for locking the end of the idler shaft, the lower part of the groove is U-shaped, and the upper part of the groove is inclined to one side, so that the lower part and the upper part of the groove form an obtuse angle.

[0005] Preferably, the main frame includes two brackets arranged side by side, with a support plate installed between the brackets, and a groove for locking the end of the roller shaft is provided at the upper end of the support plate.

[0006] Preferably, the tray has an inverted V-shaped structure.

[0007] Preferably, the bracket includes a horizontal section and inclined sections disposed at both ends of the horizontal section; one end of the inclined section is connected to the horizontal section, and the other end of the inclined section is tilted upward and connected to the support, so that an obtuse angle is formed between the inclined section and the horizontal section.

[0008] Preferably, the bottom of the support has bolt holes.

[0009] It is also necessary to provide a set of rollers for the tail section of a retractable belt conveyor.

[0010] A set of idler rollers for the tail receiving section of a retractable belt conveyor includes the aforementioned anti-drop idler roller frame for the tail receiving section of the retractable belt conveyor, and idler rollers installed on the idler roller frame.

[0011] It is also necessary to provide a conveyor.

[0012] A conveyor includes the aforementioned retractable belt conveyor tail receiving section idler roller assembly, which is mounted on the conveyor frame.

[0013] Compared with existing technologies, the retractable belt conveyor tail section idler frame provided by this utility model includes a main frame and supports symmetrically arranged on both sides of the main frame. The upper end of each support has a groove for locking the end of the idler shaft. The lower part of the groove is U-shaped, and the upper part of the groove is inclined to one side, forming an obtuse angle between the lower and upper parts of the groove. When the end of the idler shaft is locked into the groove, the inclined design of the upper part of the groove greatly reduces the probability of the idler shaft detaching from the idler support when subjected to the impact of material unloading force. This ensures the normal operation of the belt conveyor and significantly reduces the huge economic losses and coal mine accidents caused by the detachment of idlers from the idler frame at the tail of the retractable belt conveyor, resulting in downtime.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please refer to Figures 1 to 3 In one embodiment, this utility model provides a retractable belt conveyor tail section idler frame, including a main frame 01 and supports 02 symmetrically arranged on both sides of the main frame 01. The upper end of each support 02 has a groove 03 for locking the end of the idler shaft. The lower part of the groove 03 is U-shaped, and the upper part of the groove 03 is inclined to one side, forming an obtuse angle between the lower and upper parts of the groove 03. When the end of the idler shaft is locked into the groove 03, the inclined design of the upper part of the groove 03, when subjected to the impact of material unloading force, can restrict the end of the idler shaft, preventing it from detaching from the groove 03. The probability of the idler shaft detaching from the idler support 02 is greatly reduced, ensuring the normal operation of the belt conveyor and significantly reducing the huge economic losses and coal mine accidents caused by the detachment of the idler 04 from the idler frame at the tail of the retractable belt conveyor.

[0025] Of course, for the slot 03, the depth of the lower part of the slot 03 can be increased, and together with the certain angle formed by the inclination of the upper part of the slot 03, it can increase the difficulty of the roller shaft getting out of the support 02 slot 03.

[0026] To be more specific, the main frame 01 includes two brackets 11 arranged side by side, with a support plate 12 installed between the brackets 11. A groove 13 for locking the end of the roller shaft is provided at the upper end of the support plate 12.

[0027] To ensure installation stability, the tray 12 is designed with an inverted V-shape, which reduces weight while ensuring a stable connection between the lower part of the tray 12 and the bracket 11.

[0028] The bracket 11 includes a horizontal section 111 and inclined sections 112 disposed at both ends of the horizontal section 111. One end of the inclined section 112 is connected to the horizontal section 111, and the other end of the inclined section 112 curves upward and connects to the support 02, so that the inclined section 112 and the horizontal section 111 form an obtuse angle. To ensure the overall strength of the bracket 11, the horizontal section 111 and the inclined section 112 adopt an integral structure.

[0029] The support 02 has bolt holes 21 at its bottom to facilitate fixing the support 02 to the frame.

[0030] Please refer to Figures 4 to 6 In one embodiment, the present invention provides a set of idler rollers for the tail receiving section of a retractable belt conveyor, including an anti-drop idler frame for the tail receiving section of the retractable belt conveyor and idler rollers 04 installed on the idler frame. The idler rollers 04 can be installed in both the horizontal section 111 and the inclined section 112 to ensure that the idler rollers 04 can constrain the conveyor belt into an arc shape, thereby facilitating material transport.

[0031] Specifically, the tail section idler frame of the telescopic belt conveyor includes a main frame 01 and supports 02 symmetrically arranged on both sides of the main frame 01. The upper end of each support 02 has a groove 03 for securing the end of the idler shaft. The lower part of the groove 03 is U-shaped, and the upper part of the groove 03 is inclined to one side, forming an obtuse angle between the lower and upper parts. When the end of the idler shaft is engaged in the groove 03, the inclined design of the upper part of the groove 03, when subjected to the impact of material unloading force, restricts the end of the idler shaft, preventing it from detaching from the groove 03. This significantly reduces the probability of the idler shaft detaching from the idler support 02, ensuring the normal operation of the belt conveyor and greatly reducing the huge economic losses and mine accidents caused by the detachment of the idler 04 from the tail section idler frame of the telescopic belt conveyor.

[0032] Of course, for the slot 03, the depth of the lower part of the slot 03 can be increased, and together with the certain angle formed by the inclination of the upper part of the slot 03, it can increase the difficulty of the roller shaft getting out of the support 02 slot 03.

[0033] To further explain, the main frame 01 includes two brackets 11 arranged side by side, with a support plate 12 installed between the brackets 11. A groove 13 for locking the end of the roller shaft is provided at the upper end of the support plate 12.

[0034] To further explain, in order to ensure the stability of the installation, the structure of the tray 12 is designed in an inverted V shape, which reduces the weight while ensuring the stable connection between the lower part of the tray 12 and the bracket 11.

[0035] To further explain, the bracket 11 includes a horizontal section 111 and inclined sections 112 disposed at both ends of the horizontal section 111. One end of the inclined section 112 is connected to the horizontal section 111, and the other end of the inclined section 112 curves upward and connects to the support 02, so that the inclined section 112 and the horizontal section 111 form an obtuse angle. To ensure the overall strength of the bracket 11, the horizontal section 111 and the inclined section 112 adopt an integral structure.

[0036] To further explain, the bottom of the support 02 is provided with bolt holes 21 so as to fix the support 02 to the frame.

[0037] In one embodiment, the present invention provides a conveyor including a set of idler rollers for the tail receiving section of the telescopic belt conveyor, the set of idler rollers being mounted on the frame of the conveyor.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
