Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] A coal drop point spring type buffer idler assembly, such as figure 1 As shown, it includes a roller frame 1, and a bending spring 2 is installed on the roller frame 1. The two ends of the bending spring 2 are fixedly connected to the inner rings of the rolling bearings 3, and the inner rings of the two rolling bearings 3 are respectively erected by the end shafts. On the idler frame 1; the rolling bearing 3 is installed in the spring sheath 4, and the outer ring of the rolling bearing 3 is fixedly connected with the spring sheath 4; the two ends of the bending spring 2 extend into the spring sheath 4.

[0014] The spring type buffer idler assembly is mainly composed of the original Yuanbao type idler frame and bending spring. Fixing devices are installed at both ends of the bending spring to reliably connect with the Yuanbao type idle...

Abstract

The invention relates to supporting roller equipment of a belt conveyor and particularly relates to a spring-type buffering supporting roller assembly for a coal dropping point. The spring-type buffering supporting roller assembly comprises a supporting roller frame (1), wherein the supporting roller frame (1) is provided with a bending spring (2), two ends of the bending spring (2) are fixedly connected with inner rings of rolling bearings (3), and the inner rings of the two rolling bearings (3) are respectively erected on the supporting roller frame (1) through end shafts; the rolling bearings (3) are arranged in spring sheaths (4), and outer rings of the rolling bearings (3) are fixedly connected with the spring sheaths (4); and two ends of the bending spring (2) extend into the spring sheaths (4). The spring-type buffering supporting roller assembly for the coal dropping point is reasonable in design as well as simple and convenient to mount, conforms to the original design intention and can be popularized to coal mine enterprises, and a better effect can be achieved if a plurality of groups of spring-type buffering supporting roller assemblies are arranged.

Description

technical field [0001] The invention relates to idler equipment of a belt conveyor, in particular to a coal drop spring type buffer idler assembly. Background technique [0002] Belt conveyor is a kind of continuous transportation machinery widely used in mining enterprises. The impact of blocky materials on the belt during the loading and reloading process of the belt conveyor is a problem that plagues the units that use the belt conveyor. Coal drop point buffer devices commonly used in coal mines include buffer rollers and buffer beds, etc., buffer rollers are divided into spring plate type, buffer ring type, strong buffer type, adjustable elastic type, hanging type, etc. Our mines generally use trough roller brackets to install buffer rollers with rubber rings. This method has limited buffer space, cannot achieve a good buffer effect, short service life, and heavy maintenance workload. Contents of the invention [0003] The invention utilizes the longitudinal force of...
