Description

Technical Field

[0001] This utility model relates to the field of open-pit mining technology, and more specifically, to a belt pressing device for a large-angle belt conveyor. Background Technology

[0002] In open-pit mining or underground coal mining, belt conveyors are a primary conveying equipment. Sometimes, due to terrain undulations, belt conveyors will have a certain angle of inclination. In the current technology, the inclination angle of large belt conveyors used for conveying mining materials is relatively small, generally below 18°. Depending on the characteristics of different conveyed materials, the maximum conveying lifting angle of belt conveyors generally does not exceed 28°. However, in situations with large flow rates and limited transportation geographical conditions, such as when it is necessary to cross hillsides, culverts, tunnels, etc., the existing technology of large belt conveyors with small inclination angles cannot meet the requirements.

[0003] The existing technical solution has a first frame in the shape of an octagon hinged to the left and right ends of the crossbeam, a second frame in the shape of a rectangle hinged to the front and rear ends of each first frame in the shape of an octagon, and two third frames in the shape of a square hinged to the front and rear ends of each second frame. A pressure roller is installed in each third frame through a roller shaft.

[0004] Existing belt pressing devices typically only have pressure rollers installed above the cover belt, either in two sets of four-roller configurations or gravity-driven configurations. However, insufficient pressure on the sides of the carrying belt and cover belt, especially when the material is uneven, can easily lead to material leakage from the sides.

[0005] Therefore, how to improve the stability of material conveying is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0030] This utility model discloses a belt pressing device for a large-angle belt conveyor, which improves the stability of material conveying.

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 As shown, Figure 1 A schematic diagram of the layout structure of the belt pressing device for the steep-angle belt conveyor provided in this application; Figure 2 for Figure 1 Schematic diagram of the intermediate pressure belt device; Figure 3 for Figure 2 A schematic diagram of the middle side pressing device.

[0033] This application provides a belt pressing device for a large-angle belt conveyor, including a belt conveyor 4 for conveying materials, with a cover belt 41 covering the materials along its conveying direction; it also includes an intermediate belt pressing device 2 mounted above the belt conveyor 4 to elastically press the middle of the cover belt 41; and side belt pressing devices 3 distributed on both sides of the belt conveyor 4 in the width direction to elastically press the cover belt 41. The cover belt 41 is provided on the surface of the materials conveyed by the belt conveyor 4, covering the material surface and conveying synchronously with the belt conveyor 4. The intermediate belt pressing device 2 is provided above the belt conveyor 4 to press the cover belt 41 on the material. The side belt pressing devices 3 on both sides of the belt conveyor 4 make the cover belt 41 adhere tightly to the belt conveyor 4 for pressing and conveying. The cover belt 41 and the belt conveyor 4 are closely attached in the conveying direction, improving the stability of material conveying.

[0034] In a specific embodiment of this case, the intermediate belt pressing device 2 includes a swing beam 204 and a plurality of intermediate belt pressing rollers 205 distributed along the length of the swing beam 204; it also includes a hinge seat 203 hinged to the middle of the swing beam 204, providing swing support in the pressing direction of the swing beam 204. Adapted to the belt conveyor 4 during material transport, where the material accumulates in the middle and overturns to both sides of the belt conveyor 4 in the width direction, resulting in a boss-like structure, a swing beam 204 extending laterally along the belt conveyor 4 is provided, and a plurality of intermediate belt pressing rollers 205 are arranged on the swing beam 204. The rolling direction of the intermediate belt pressing rollers 205 is arranged along the conveying direction of the belt conveyor 4, so that the intermediate belt pressing rollers 205 roll while pressing. Considering the unevenness of material accumulation on both sides of the transverse direction, the swing beam 204 is configured to swing up and down at both ends along its length. The swing beam 204 is hinged and supported by the intermediate hinge seat 203, allowing the intermediate pressure roller 205 to press the cover belt in a jumping motion, reducing hard impacts and improving service life. Preferably, the intermediate pressure roller 205 includes two rollers located at both ends of the swing beam 204 along its length. The swing direction of the swing beam 204 is along the pressing direction of the cover belt 41, causing the swing beam 204 to swing along the height direction of the conveying surface of the belt conveyor 4.

[0035] Furthermore, it also includes an upper mounting plate 201 for hoisting the hinge seat 203, an inner sleeve 211 is mounted on the upper mounting plate 201, and an outer sleeve 213 is provided on the hinge seat 203; it also includes an elastic compression device 202 connected between the upper mounting plate 201 and the hinge seat 203 to elastically support the sliding of the inner sleeve 211 and the outer sleeve 213.

[0036] Preferably, the elastic compression device 202 is a compression spring fitted onto the outer sleeve 213.

[0037] Considering the unevenness of material particles during the conveying process of belt conveyor 4, and the need for the intermediate pressure roller 205 to continuously press the cover belt 41, in order to avoid the impact of large particles on the intermediate pressure roller 205, the intermediate pressure roller 205 is designed as an elastic support structure.

[0038] By setting an inner sleeve 211 and an outer sleeve 213 that fit together between the upper mounting plate 201 and the hinge seat 203, and simultaneously fitting a compression spring around the outer sleeve 213, the surface of the cover belt 41 is subjected to a stable clamping force provided by the compression spring, and elastic buffering is achieved when encountering large particles, thereby improving safety.

[0039] In one specific embodiment of this case, the side pressing device includes an upper pressing roller 304 and a lower pressing roller 303 arranged in parallel, and a pressing gap is formed between the upper pressing roller 304 and the lower pressing roller 303 for the laminating cover belt 41 and the drive belt 42 of the belt conveyor 4 to pass through.

[0040] Furthermore, the belt conveyor 4 is also provided with a side rail 305 that is substantially perpendicular to the drive belt. A side frame 301 is slidably arranged on the side rail, and a support frame for supporting the upper pressure roller 304 and the lower pressure roller 303 extends from the side frame 301. During the conveying process of the belt conveyor 4, the weight of the material will cause the side of the conveyor belt 42 to tilt to a certain extent and vibrate during the conveying process. In order to ensure that the side cover belt 41 provides stable pressure on the drive belt 42, and to ensure that the upper pressure roller 304 and the lower pressure roller 303 are stably pressed against the surface of the cover belt 41 and the drive belt 42, a side rail that is substantially perpendicular to the drive belt 42 is provided. The upper pressure roller 304 and the lower pressure roller 303 can swing in the direction of pressing the drive belt 42 and the cover belt 41, thereby ensuring the pressing capacity and preventing material leakage.

[0041] In one specific embodiment of this case, the support frame includes a lower support frame that is fixedly mounted on the side frame 301 and supports the lower pressure roller 303;

[0042] And an upper support frame that is slidably arranged on the side frame 301 and slides up and down along the side rail 305;

[0043] A tension spring 302 is provided between the upper support frame and the lower support frame to elastically tension them. In one specific implementation, the upper support frame is an upper support column arranged coaxially with the upper pressure roller 304, and the lower support frame is a lower support column arranged coaxially with the lower pressure roller 303. The lower support column is fixedly connected to the side frame 301, and the upper support column is slidably connected to the side rail.

[0044] In this embodiment, the side rail is a side mounting plate extending laterally from the side frame, and the side mounting plate is provided with a side frame groove to guide the sliding of the upper support frame. The side rail 305 is used to guide the sliding of the lower support frame towards or away from the cover belt 41. In a preferred structure, the side rail 305 is set as a side mounting plate with a flanged structure extending from the side frame 301. The extension direction of the side mounting plate is arranged substantially perpendicular to the side of the belt conveyor 4. The upper pressure roller is slidably arranged on the side mounting plate in the direction of approaching or away from the cover belt, so the sliding direction of the upper pressure roller 304 is the direction of approaching or away from the cover belt 41. A side frame groove is provided on the side mounting plate, and the upper support frame slides and is guided within the groove. A tension spring 302 is provided between the upper support frame and the lower support frame, so that the tension spring 302 maintains the clamping force on the cover belt 41, and can slide within the groove to buffer the impact when subjected to impact.

[0045] Furthermore, the side belt pressing device 3 includes a set symmetrically arranged in the conveying direction of the belt conveyor 4. By pressing the belt conveyor 4 on both sides in the width direction with two side belt pressing devices 3 respectively, the conveying stability at both ends of the belt conveyor 1 is ensured.

[0046] In one specific embodiment of this case, a support beam is also included for hoisting the intermediate belt pressing device and the side belt pressing device. The support beam spans above the belt conveyor. By spanning the width of the belt conveyor 4, the support beam provides stable support for the intermediate belt pressing device and the side belt pressing device. The support beam 1 can be supported by independent support legs, or it can utilize the existing frame structure of the belt conveyor 4 for support.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
