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 face.
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, 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, to the research of mining steeply dipping coal seam, will be the key subjects of western coal exploitation.2. the exploitation of many years has made at the coal seam reserves of east mining area 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.Far below gently inclined seam, exist a series of fundamental technics difficult problems that solve that do not have due to the current development level of mining steeply dipping coal seam, be mainly that support work labour intensity is large, at the bottom of the rate of extraction, work plane transportation difficulty etc.
The normal means of transportation adopted of large inclination working surface is gravity haulage or drag conveyor transportation.When seam inclination is large, can slip coal or lay chute along floor undulation, transportation is simple, take equipment and manpower is few, but the uncontrollable coal speed of slipping, when coal can produce and impact 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 while 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.The present invention is intended to solve the Coal Transport problem of stope when large-inclination-angle coal bed middle layout is moved towards the coal wall exploitation.
Summary of the invention:
The transportation problem existed in order to solve current large angle mining work, 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 big angle coal face automatic retarding chute, the theing contents are as follows of this invention:
The automatic retarding 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 chute is too fast, induction installation is produced to larger impact, tablet rotates counterclockwise along axis of rotation, the traction brake flap rotates, reduce coal and pass through space, increase coal from slipping resistance, reduce coal from slipping speed, when a large amount of coal passes through brake flap, brake flap is produced and impacts, brake flap is rotated counterclockwise along axis of rotation, the traction tablet clockwise rotates, restPose, realize the automatic speed regulation process.
The accompanying drawing explanation:
Fig. 1 big angle coal face automatic retarding chute schematic diagram
In 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 with axis of rotation 5 first is installed when every group of chute installed, chute is connected tablet 4 and brake flap 5 is installed on chute, and then logical files control lever 6 is connected tablet 4 and brake flap 7.
2, adjust initial resistance
When initial stage installation and seam inclination change, the angle that can regulate between tablets and chute by tablet angle regulator 8, in order to adjust the lower slip resistance of coal.
3, slow down
When a large amount of coals, in chute, glide fast while impacting tablet 4, tablet 4 rotates counterclockwise along axis of rotation 5, drives brake flap 7 by control lever 6 and clockwise rotates, and reduces coal by space, increases slip resistance under coal, reduces Coal Transport speed.
4, recover
, brake flap 7 is produced and impacts when the brake flap 7 when a large amount of coal, slowing down 7 rotates counterclockwise, and drives tablets 4 by control lever 6 and clockwise rotates, and restPoses, and with this, realizes the automatic speed regulation process.
5, applicable place
Figure 1 shows that left work plane automatic retarding chute, if need to make chute mirror image entity of the present invention while using in right work plane, or the rear use of position transposing with brake flap 7 by tablet 4.
Claims (2)
1. big angle coal face automatic retarding chute, it is characterized in that: tablet (4) upper end is connected with spillplate (3) by tablet angle regulator (8), middle part connects by axis of rotation (5) and chute bottom hinge, and lower end and control lever (6) are hinged; Brake flap (7) middle part connects by axis of rotation (5) and chute bottom hinge, and upper end and control lever (6) are hinged; Control lever (6), upper and lower two ends are hinged with tablet (4) and brake flap (7) respectively, between control lever two parts, are slidably connected; Tablet (4) drives brake flap (7) and turns clockwise while being rotated counterclockwise, play the effect that reduces Coal Transport speed, be rotated counterclockwise after brake flap (7) is impacted, drive tablet (4) and turn clockwise, and restPose.
2. big angle coal face automatic retarding chute according to claim 1, described tablet angle regulator (8) be adjustable springs, by its elongation with shorten the initial angle of regulating tablet (4).
