Abstract
The invention relates to an automatic speed regulation chute for a large inclination-angle coal face. Large inclination-angle coal beds are widely distributed in China. Due to large inclination angle of the stope face, all the transportation modes adopted at present have certain defects. In order to overcome the defects in the transportation modes which are often used on the stope face at present, the invention provides an automatic speed regulation chute. The automatic speed regulation chute comprises a common chute, a speed sensor and a reduction gear. When the transportation speed of the coal in the chute is too high, a sensing plate descends to pull a speed reduction plate at the lower part to rise, thereby increasing the resistance force of the automatic slide of the coal; and when a great deal of coal passes through the speed reduction plate, the speed reduction plate is impacted to descend to pull the sensing plate to rise, thereby realizing the process of automatic speed regulation. Thus, the invention has the advantages of low cost, simple installation technique, easy movement, and safe and reliable transportation, and can adapt to the chute with changes of the inclination angle of the coal bed.
Description
Technical field: the present invention is applied to a kind of haulage device of big angle coal face.
Background technology:
The large-inclination-angle coal bed coal seam of seam inclination between 35 ° ~ 55 ° of generally referring to.Arrange in such coal seam when moving towards the coal wall exploitation, the normal means of transportation that adopts is gravity haulage or drag conveyor transportation.Safe and reliable when adopting the drag conveyor transportation, but large inclination working surface equipment is installed, the passing complex procedures, not only will take equipment, manpower, also will solve conveyer downslide problem, and speed of production is had a great impact; If the employing gravity haulage can be slipped coal or lay chute along floor undulation, transportation is simple, take equipment and manpower is few, but in the large inclination working surface situation, because the gradient of the face of working is steeper, so the uncontrollable coal speed of slipping, impact and can produce lower part equipment when slipping excessive velocities when coal, when serious, the coal chute of can leaping up out, fly into work plane, causes casualty accident, when especially the work plane change of pitch angle is large, adopt a kind of haulage device to satisfy work plane movement requirement difficulty especially.
Summary of the invention:
In order to solve the deficiency of the means of transportation that present stope often adopts, invention a kind of cost low, mounting process is simple, easily mobile, transportation safety is reliable, and can adapt to a kind of chute that seam inclination changes, be referred to as the automatic speed regulation chute, the theing contents are as follows of this invention:
The automatic speed regulation chute is comprised of common chute, speed sensor and deceleration device, each speed sensor and deceleration device are hinged with a common chute of joint respectively, one overlaps speed sensor and is no more than one group of five cover deceleration devices composition, middle with the control lever connection, uses in groups.When the coal travelling speed in chute is too fast, induction installation action, traction bottom brake flap rise, increase coal from slipping resistance, when a large amount of coals pass through brake flap, brake flap is produced impact, brake flap descends, and the traction tablet rises, and realizes the automatic speed regulation process.
Description of drawings:
Fig. 1 automatic speed regulation chute
In figure: the 1-chute; The 2-tablet; The 3-brake flap; The 4-control lever; The 5-adjuster; 6-chute joint cover; The 7-fixed-hinged support.
The specific embodiment:
1, the installation of chute
From the bottom to top, the chute with brake flap is installed first when every group of chute installed, by control lever 4, tablet 2 and brake flap 3 connections is connected after chute is connected.
2, adjust initial resistance
When initial stage installation and seam inclination change, can be by the angle between adjuster 5 adjusting brake flaps and chute, in order to adjust the lower slip resistance of coal.
3, slow down
In chute during rapid movement, tablet 2 descends, and drives brake flaps 3 by control lever 4 and rises, and increases slip resistance under coal when a large amount of coals.
4, recover
When a large amount of coals pass through brake flap 3, brake flap 3 is produced impact, brake flap 3 descends, and 2 rises of traction tablet realize the automatic speed regulation process.
Claims (2)
1. big angle coal face automatic speed regulation chute, it is characterized in that: tablet (2) one ends connect by axle and chute bottom hinge, and an end and control lever (4) are hinged; Brake flap (3) one ends connect by axle and chute bottom hinge, and an end and control lever (4) are hinged; Control lever (4) middle part is hinged with fixed-hinged support (7), and two ends are hinged with tablet (2) and brake flap (3) respectively; Driving brake flap (3) when tablet (2) descends rises, drive tablet (2) when brake flap (3) descends and rise, can realize that coal slips the purpose of slowing down in process certainly by tablet (2) and brake flap (3) interaction.
2. big angle coal face automatic speed regulation chute claimed in claim 1, also comprise adjuster (5), and described adjuster (5) is arranged on control lever (4), can pass through the length that adjuster (5) changes control lever (4).
