Abstract
The invention relates to an auxiliary device of a belt conveyer, in particular to a belt slope-variable device. The belt slope-variable device comprises a first fixed leg pair and a second fixed leg pair, wherein the first fixed leg pair and the second fixed leg pair are sequentially fixed at a concave section of an excavation roadway in the belt conveying direction, four fixed legs in the first fixed leg pair and the second fixed leg pair are located on the four corners of a rectangular area where the fixed legs are located respectively, the first fixed leg pair is provided with a first carrying roll, the second fixed leg pair is provided with a second carrying roll higher than the first carrying roll, and any fixed leg pair is provided with a belt pressing carrying roll. The belt slope-variable device effectively resolves the problems that as the slope of some sections of the excavation roadway is large, a belt flies upwards and is suspended in the conveying process and the safety of passing workers is threatened, reduces the hidden risks that the belt is torn, prolongs the service life of the belt, and reduces the replacement frequency of the belt.
Description
Technical field
The present invention relates to the auxiliary device of belt feeder, be specially belt slope changing device.
Background technology
The digging laneway complicated geological of present coal mining enterprise underground construction, the existence of recessed section that on digging laneway, radius of curvature is less is inevitable, when belt on belt transporter is by recessed section, belt can be made to produce unsettled, now belt grooving situation changes, because belt have left trough idler group, general groove angle diminishes, partial material is made to spread out, therefore, recessed section of larger radius of curvature should be adopted as much as possible to avoid this type of circumstances from happening at design phase, but some situation is difficult to avoid in actual production, recessed section of radius of curvature larger part can set up pinch roller to avoid upspringing of belt, but recessed section that radius of curvature is less just produces little effect, spreading coal, to fall cash just unavoidable, and the bulk spoil dropped also causes security threat to the workman in advancing, there is no small potential safety hazard, in addition, recessed section place belt unsettled be easy to less at radius of curvature makes belt and top board swipe, and causes belt tearing, cut appears in belt, reduce the service life of belt.
Summary of the invention
The present invention in order to the belt that solves belt transporter by digging laneway radius of curvature little recessed section time, easily cause the problem of safety misadventure and damage belt, provide belt slope changing device.
The present invention adopts following technical scheme to realize: belt slope changing device, comprise the first Convenient table of being fixed on recessed section of digging laneway place along belt transport direction successively to the second Convenient table pair, first Convenient table lays respectively on four corners of rectangular area, Convenient table place to four Convenient tables with the second Convenient table centering, first Convenient table is to being provided with the first carrying roller, second Convenient table is to being provided with second carrying roller of height higher than the first carrying roller, and any Convenient table is also provided with pressure zone carrying roller to upper.
During use, when belt normally runs through recessed section of digging laneway, first be wrapped on the second carrying roller, then be wrapped on the first carrying roller, finally be wound on the head roll of belt conveyer head, when return belt is by this recessed section, under return belt is pressed in pressure zone carrying roller, belt after belt before second carrying roller and the first carrying roller is supported in trough idler group, this device is coordinated by the first carrying roller and the second carrying roller, belt is supported on the first carrying roller and the second carrying roller through recessed section time, and can not produce unsettled, material is not easy to scatter, simultaneously because the first carrying roller and the second carrying roller have diff-H, material on belt before second carrying roller is through the second carrying roller, material can drop on the belt after the first carrying roller, complete the transport of material, pressure zone carrying roller can push down return belt, make return belt not recessed section of place's bounce-back.
Above-mentioned belt slope changing device, first Convenient table all comprises stationary pipes to the Convenient table with the second Convenient table centering and is enclosed within the adjustable pipe of sliding in stationary pipes, along stationary pipes, first carrying roller and the second carrying roller are all fixed in adjustable pipe, namely can adjust the height of the first carrying roller and the second carrying roller, the operating needs of recessed section of different curvature radius can be met.
This belt slope changing device efficiently solve digging laneway part location because of the gradient large, occur belt to waft and the unsettled threat caused safely holdee in transportation, decrease belt tearing hidden danger, extend belt service life, decrease belt replacing frequency.Become slope guide piece and be used in recessed section of less place of radius of curvature, for belt transportation system enhances safety factor, solve again the labour intensity clearing up float coal increase after coal is spread at this place simultaneously, greatly save manpower and materials input cost, for mine provides larger economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-first Convenient table pair, 2-second Convenient table pair, 3-first carrying roller, 4-second carrying roller, 5-pressure zone carrying roller.
Detailed description of the invention
Belt slope changing device, comprise the first Convenient table of being fixed on recessed section of digging laneway place along belt transport direction successively to 1 and second Convenient table to 2, first Convenient table to 1 and second Convenient table lay respectively on four corners of rectangular area, Convenient table place to four Convenient tables in 2, first Convenient table is provided with the first carrying roller 3 to 1, second Convenient table is provided with second carrying roller 4 of height higher than the first carrying roller 3 to 2, and any Convenient table is also provided with pressure zone carrying roller 5 to upper.
Above-mentioned belt slope changing device, the first Convenient table to 1 and second Convenient table stationary pipes is all comprised to the Convenient table in 2 and is enclosed within the adjustable pipe of sliding in stationary pipes, along stationary pipes, the first carrying roller and the second carrying roller are all fixed in adjustable pipe.
