Problems solved by technology
[0002] In the construction of general coal mine excavation area, it often encounters the problem of turning at a small angle and the extension of the belt conveyor. For example, the design length of the SD-80 belt conveyor for the third part of the 681 machine lane of the applicant is 450m, and the construction reaches the third part of the 681 machine lane. 17m before point S16 of the belt conveyor (the third SD-80 belt conveyor 215m) encountered a fault. In order to avoid the adverse impact of the fault on coal recovery, according to the design of the technical department, the machine lane turned left 9°, turned left and headed The coal seam was affected by the fault, and the roof went downhill at 6°. As a result, the construction went downhill by 8m, which made it difficult to extend the belt conveyor
According to the conventional belt installation method, the reversing roller and the reversing frame need to be installed at the turning position, which occupies a large area during installation, and the turning angle is also large, resulting in power consumption and increasing the friction loss of the belt conveyor
At present, cornering devices are generally installed to solve the cornering problem when the curvature is large, but it is uneconomical and impractical to install a turning device at a position with a small curvature

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] Such as figure 1 , figure 2 As shown, the belt conveyor 1 of the present invention comprises an inner side H frame 2, an outer H frame 3, and an idler 4 is arranged between each corresponding inner side H frame 2 and the outer H frame 3, and the idler roller 4 is provided with Belt 5, belt 5 is driven by power and transmission device, and the bottom of inside side H frame 2 and outside H frame 3 is also provided with connecting frame 6.
[0016] The method of the present invention includes two aspects. On the one hand, determine the curve radius R of the installation roadway and the theoretical arc length k on the outside of the curve section according to the head-on fault situation, and reserve the distance and space for the belt conveyor to gradually shift to the inside at the inflection point of the roadway, and then Brush the section of ...

The invention relates to a belt conveyer and a method for realizing small-angle turning of the belt conveyer in inclined roadways. The method comprises the following steps: 1) setting a curve radius R of an installation roadway and the theoretical arc length k of the outer side of a curved section according to a head-on faultage condition; 2) widening the section of the roadway at the inner side according to the set curve radius R and the set theoretical arc length k of the outer side of the curved section, thereby remaining a distance and a space for the belt conveyer to shift gradually from the inflection point to the inner side of the roadway; 3) calculating the elevation magnitude of an H rack at the outer side of the belt conveyer according to a formula; and 4) calculating the numerical value of the elevation magnitude of an H rack at the outer side of the belt conveyer according to step 3, gradually lifting the H rack at the outer side of the belt conveyer at the straight line section of two ends of the curved section to a regulated numerical value at the beginning of the curved section, and maintaining the elevation value of the H rack at the outer side of the belt conveyer at the curved section until the H rack at the outer side of the belt conveyer begins to lower and returns to the original position at the terminal of the curved section, thereby finishing the small-angle turning of the belt conveyer in the inclined roadway. In start with heavy load, the phenomena of belt shifting and outward deflection do not occur, the production requirement can be met, and the invention can be widely used in the turning of the belt conveyer in an inclined roadway.
