Travelling apron claims again band conveyor, is the main transportation device of present coal mine operation, is undertaking transportation tasks out such as the coal under the coal mine, spoils.Because complex geologic conditions under the coal mine, tomography is grown, and the coal road tunnel rises and falls more frequent, and local relief is larger, causes travelling apron fortune coal difficulty.The larger location of colliery fluctuating roadway slope change point angle, travelling apron are when No Load Start, and belt causes these section three carrying rollers to pound easily owing to the effect that is subject to suddenly tensile force can pop up and fall, and has device security hidden danger; The grade change point place also unsettled phenomenon can occur when the coal amount is less, the travelling apron sideslip very easily occurs, spills coal, and spilling needs the labor cleaning behind the coal, has increased operating personnel's labour intensity.
Travelling apron the unsettled material that spills occurs at grade change point two kinds of situations:
The one, spill material when belt is unsettled at grade change point (recessed section): in recessed section belt interval, hour belt to be produced unsettled when recessed section radius of curvature, and this moment, belt left the trough idler group, made partial material spill.The 2nd, spill material during belt deviation: during belt deviation spilling material be because belt when operation, variation has been along highly having occured in its dual-side, on one side high, and another side is low, material spills from low one side.Solve these two kinds and spill the material situation, the main belt pressing device that adopts makes the belt of travelling apron that a downward pressure be arranged, and prevents that belt from popping up and unsettled, prevented in the larger location of colliery fluctuating roadway slope change point angle, because belt hikes up the problems such as coal, sideslip of spreading that cause.
The belt pressing device of commonly using at present, main cylinder or the straight carrying roller of using is installed at the belt top, because the position that cylinder or carrying roller are installed is fixed, although when belt feeder slips car, can play the effect of pressure zone, but when normally producing coal, hinder the phenomenon of producing coal if cylinder then can appear greatly in the coal amount, causing produces coal has some setbacks.
Summary of the invention
The present invention will solve above-mentioned deficiency exactly, and a kind of simple in structure, effective simple and easy belt pressing device that is used for travelling apron is provided, and prevents that belt from hiking up and the problems such as coal, sideslip of spreading that cause.
In order to reach above-mentioned effect, the invention provides a kind of simple and easy belt pressing device of travelling apron, comprise the straight carrying roller of belt feeder, the two ends of the straight carrying roller of described belt feeder are installed on the H type support, and described H type props up the belt both sides of the travelling apron that is set up in roadway slope change point place; The centre of the straight carrying roller of described belt feeder successively interval is installed with left annular pinch roller, middle annular pinch roller and right annular pinch roller.
The diameter of described middle annular pinch roller is larger than the diameter of left and right annular pinch roller; The diameter of left and right annular pinch roller is identical.
The bottom of described H type support by earth anchorage on ground, tunnel.
This device is installed in the larger location of fluctuating roadway slope change point angle, and namely unsettled location appears easily in travelling apron, annular pinch roller just in time be positioned at belt directly over and with belt one section buffer distance is arranged.
After this device was installed, travelling apron was when no-load run, and belt pops up, and at this moment because the effect of three annular pinch rollers, the belt very low height of can only upspringing has been alleviated the tension force of belt; In the coal amount hour, because middle annular pinch roller slightly larger in diameter is in the left and right annular pinch roller diameter on both sides, so belt still keeps certain umbilicate radian, the coal amount hour can not occur spilling the coal phenomenon yet, has guaranteed the normal operation of belt feeder; When normally producing coal, belt is subject to the effect of the pressure of coal, falls to the normal position operation, even the coal amount is larger, owing to have very large space between three annular pinch rollers, can hinder normally and produce coal.Simultaneously H type support and ground is by earth anchorage, prevents belt when being subject to the tensile force effect and popping up, and the elastic force that makes progress acts on can drive H type support generation displacement on the annular pinch roller.
By installing and using of simple and easy belt pressing device, solved because belt hikes up the problems such as coal, sideslip of spreading that cause, this simple and easy belt pressing device is compared with traditional belt pressing device, simple in structure, be convenient to process, advantage that cost is lower, easy for installation, reduce the labour intensity that the worker manually sweeps coal, obtained considerable economic benefit.
