Embodiment 1

[0053] Such as figure 1 As shown, this embodiment provides a tensioning device for a belt conveyor, which includes a swimming structure 1 , an adjusting rope, a pulley block, a driving structure and an elastic telescopic structure 4 .

[0054] In this embodiment, the swimming structure 1 includes a traveling trolley and a tensioning roller, a belt is wound on the tensioning roller, and a pulley block is fixed on the traveling trolley.

[0055] The adjusting rope is a steel wire rope 2, and the driving structure is a tensioning winch 3. One end of the wire rope 2 is fixed on the frame 8 of the belt conveyor, and the other end has a longer margin, which is wound on the tensioning winch 3 to adjust the position of the traveling trolley. The tensioning winch 3 has a large tensioning stroke adjustment range, can accurately control the tensioning force, and has a stable and adjustable growth speed. In this embodiment, the JZB-6 tensioning winch 3 is selected, the diameter of the s...

Embodiment 2

[0065] This embodiment provides a belt conveyor, which includes a frame 8, a roller set, idler rollers and a belt, and also includes the tensioning device of Embodiment 1. The drum set includes a driving drum and a transmission drum, the driving drum and the driving drum are arranged on the frame 8, and the belt is wound on the drum set.

[0066] One end of the wire rope 2 of tensioner is fixed on the frame 8. Preferably, the tensioning device is arranged at the tail of the belt conveyor, and the tensioning roller is arranged on the lower belt.

Embodiment 3

[0068] This embodiment provides a method for adjusting the belt conveyor, using the tensioning device of Embodiment 1 to adjust the tension of the belt, including the following steps:

[0069] S1: Before the belt conveyor is started, the driving structure is started to shorten the steel wire rope 2, and drive the tensioning roller to tighten the belt. The elastic telescopic structure 4 is compressed during the belt tensioning process and stores elastic potential energy.

[0070] S2: When the pre-tensioning force on the belt reaches 1.3-1.5 times of the tension value during stable operation, stop the operation of the tensioning winch 3, fix the length of the wire rope 2, start the belt conveyor, and the belt is under the friction of the roller Start spinning.

[0071] S3: The belt gradually rotates to a steady state at a constant speed, and the required tension decreases and stabilizes. At the same time, the elastic telescopic structure 4 compressed in step S1 is gradually ext...

Abstract

The invention relates to a tensioning device of a belt conveyor, the belt conveyor and an adjusting method. The tensioning device comprises a moving structure, an adjusting rope, a pulley block, a driving structure and an elastic stretchable structure, wherein a belt is arranged on the moving structure in a sleeve mode, the pulley block is arranged on the moving structure, one end of the adjusting rope is fixed, the other end bypasses the pulley block and is connected to the driving structure, the driving structure drives the adjusting rope and the moving structure to move so as to adjust the tensioning force on the belt, and the elastic stretchable structure is connected to the adjusting rope and adjusts the pulling force on the adjusting rope in a stretchable mode. According to the tensioning device, the adjusting rope and the moving structure are pulled through the driving structure, then the belt is driven to stretch out and draw back, coarse adjustment of the belt tensioning force is achieved, the elastic stretchable part can compensate the tension of the adjusting rope in real time, it is ensured that the force applied to the moving structure by the adjusting rope is stabler, the tension on the belt is maintained within the numerical range meeting the requirement, and automatic and accurate adjustment of the tension on the belt is achieved.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a belt conveyor tensioning device, a belt conveyor and an adjustment method. Background technique [0002] Belt conveyor, also called belt conveyor, is a kind of mechanical equipment that is driven by friction to transport materials in a continuous manner. It has the characteristics of large transportation volume, complex working environment, strong carrying capacity, and long transportation distance. It is widely used. Compared with transportation methods such as cars, belt conveyors can save energy and protect the environment, and can effectively reduce energy consumption and provide economic benefits. [0003] The belt conveyor includes frame, belt, idler roller, pulley, tensioning device, transmission device, etc. The pulley includes a driving pulley and a driving pulley. The rotating pulley of the belt conveyor is the driving pulley, and the other pulley ...
