Abstract
The invention relates to an automatic deceleration downspouting on a large-obliquity mining working surface, aiming at solving the problems of transportation difficulty, transportation process complexity, and the like of a traditional large-obliquity stope working surface. The automatic deceleration downspouting on the large-obliquity mining working surface comprises a common downspouting, a coal-shoveling plate, a coal-blocking plate, an impact sensing device and a speed reducer. When the transportation speed of coal in the downspouting is overhigh or the carbon amount of the coal is excessive, and the self flowing speed of the coal can be automatically adjusted through rotating a sensor board. The downspouting has high efficiency, low cost, simple mounting process, convenience in movement and safe and reliable transportation, can suit for the obliquity variance of a coal bed and has the advantages of improving working surface transportation safety and lightening labor intensity on working surface transportation.
Description
Technical field: the present invention is applied to a kind of haulage device of high inclination-angle coal mining work plane.
Background technology:
The large-inclination-angle coal bed inclination angle lower limit that is often referred to is at 30 °～35 °, the coal seam of the inclination angle upper limit in 50 °～55 ° scopes, this class coal seam more and more causes the attention on mining circle in China, and reason has two aspects: 1. western the tax has a large amount of large-inclination-angle coal bed more than 35 °.The Sichuan of leading coal producing province (district), Chongqing, Yunnan, Guizhou, Xinjiang, Gansu, Ningxia etc., large-inclination-angle coal bed is the main mining coal seam of many mining areas or mine.Along with 21 century Mineral Resources in China exploitation emphasis moves westwards, will be the key subjects of western coal mining to the research of mining steeply dipping coal seam.2. the exploitation in many years has made at the coal seam reserves of mining area, east occurrence condition " superior " fewer and feweri, many mines turn to complicated mining steeply dipping coal seam, obviously, keep these mining area high-yield and high-efficiencies and sustainable development just must solve large-inclination-angle coal bed production technique problem.Because the present development level of mining steeply dipping coal seam, exists a series of fundamental technics difficult problems that solve of not have far below gently inclined seam, mainly be that support work labour intensity is big, at the bottom of the rate of extraction, work plane transports difficulty etc.
The normal means of transportation that adopts of large inclination working surface is gravity haulage or drag conveyor transportation.When seam inclination is big, can or lay chute along work plane base plate slide coal, transportation is simple, take equipment and manpower is few, but uncontrollable slide coal speed is impacted when coal can produce lower part equipment when slipping excessive velocities, the coal chute of can leaping up out when base plate injustice or chute turn to, fly into work plane, cause casualty accident; 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 very big influence.The present invention is intended to solve the Coal Transport problem of arranging stope when moving towards the coal wall exploitation in large-inclination-angle coal bed.
Summary of the invention:
In order to solve the transportation problem that present high inclination-angle actual mining exists, improve the safety of work plane transportation, the labour intensity of reduction work plane transportation, the invention a kind of with low cost, mounting process is simple, conveniently moving, transportation safety is reliable, and can adapt to a kind of chute that seam inclination changes, be referred to as the high inclination-angle coal-face chute that slows down automatically, the theing contents are as follows of this invention:
Automatically the deceleration chute is by common chute, ramp plate, spillplate, impacting induction installation and deceleration device forms, each impacts induction installation and deceleration device is hinged by axis of rotation and the common chute of a joint, impact between induction installation and deceleration device and be connected by control lever, when the coal travelling speed in the chute is too fast, induction installation is produced bigger impact, tablet rotates counterclockwise along axis of rotation, the traction brake flap rotates, reduce coal and pass through the space, increase coal from slipping resistance, reduce coal from slide speed, when a large amount of coals pass through brake flap, brake flap is produced impact, brake flap is rotated counterclockwise along axis of rotation, the traction tablet clockwise rotates, and restPoses, and realizes the automatic speed regulation process.
Description of drawings:
Fig. 1 high inclination-angle coal-face chute schematic diagram that slows down automatically
Among the figure: the 1-chute; 2-producing coal plate; The 3-spillplate; The 4-tablet; The 5-axis of rotation; The 6-control lever; The 7-brake flap; 8-tablet angle regulator
The specific embodiment:
1, the installation of chute
From the bottom to top, the chute that has axis of rotation 5 is installed earlier when every group of chute installed, chute connects installs tablet 4 and brake flap 5 on chute, and logical then files control lever 6 connects tablet 4 and brake flap 7.
2, adjust initial resistance
When initial stage installation and seam inclination change, can be by the angle between tablet angle regulator 8 adjusting tablets and the chute, so that adjust the following slip resistance of coal.
3, slow down
When a large amount of coals glided impact tablet 4 fast in chute, tablet 4 rotated counterclockwise along axis of rotation 5, drives brake flaps 7 by control lever 6 and clockwise rotates, and reduces coal by the space, increases slip resistance under the coal, reduces Coal Transport speed.
4, recover
When a large amount of coals pass through brake flap 7, brake flap 7 is produced impact, deceleration 7 rotates counterclockwise, and drives tablets 4 by control lever 6 and clockwise rotates, and restPoses, and realizes the automatic speed regulation process with this.
5, be suitable for the place
Figure 1 shows that the left work plane chute that slows down automatically,, or the tablet 4 and the transposing back, position of brake flap 7 are used if then need make chute mirror image entity of the present invention when in right work plane, using.
Claims (5)
1. the high inclination-angle coal-face chute that slows down automatically can reduce coal by the space by interacting between tablet (4) and the brake flap (7), reduces coal from slide speed.
2. tablet according to claim 1 (4) is characterized in that: tablet (4) upper end is connected with spillplate (3) by tablet angle regulator (8), and the middle part connects by axis of rotation (5) and chute bottom hinge, and lower end and control lever (6) are hinged.Tablet (4) drives brake flap (7) and turns clockwise when being rotated counterclockwise, play the effect that reduces Coal Transport speed.
3. brake flap according to claim 1 (7) middle part is connected with at the bottom of the chute by axle, and upper end and control lever (6) are hinged.Be rotated counterclockwise after brake flap (7) is impacted, drive tablet (4) and turn clockwise, and restPose.
4. control lever according to claim 2 (6), two ends are hinged with tablet (4) and brake flap (7) respectively up and down, are slidingly connected between control lever two parts.
5. tablet angle regulator according to claim 2 (8) is adjustable springs, extends the initial angle of regulating tablet (4) with shortening by it.
