Abstract
The utility model discloses an inclined-mine forking uncoupling filed. The inclined-mine forking uncoupling filed solves the problem that a traction tramcar is prone to derailment and rollover when running in an uncoupling field which is connected with a mine shaft and a horizontal main roadway below a coal mine. According to the inclined-mine forking uncoupling filed, a forking turnout, and a tramcar transition arc turnout are arranged in an connecting roadway of an inclined mine shaft and an uncoupling forking roadway, one end of the forking turnout is connected with a tramcar rail arranged in the inclined mine shaft, the other end of the forking turnout is connected with one end of the tramcar transition arc turnout, and the other end of the tramcar transition arc turnout is connected with a tramcar rail arranged in the uncoupling forking roadway. The frog angle alpha1 of the forking turnout, the radian alpha2 of a tramcar turnout transition arc rail, the included angle beta between the inclined mine shaft and the horizontal plane, the width B of the uncoupling forking roadway meets the following relational expressions: delta= k*arcsin[tan10*cos beta1] and beta1= arcsin [cos (alpha1+alpha2)*sin beta], wherein k is a constant, k is less than or equal to 0.8 and larger than or equal to 0.6. The inclined-mine forking uncoupling filed improves the coefficient of safe operation of the tramcar in the underground inclined-mine forking uncoupling field.
Description
Technical field
The present invention relates to a kind of parking lot of uncoupling that pit shaft and horizontal Da Xiang junction arrange that under coal mine, connects, particularly a kind of inclined shaft that under coal mine, connects pit shaft and the junction setting in the large lane of level field of uncoupling of diverging.
Background technology
In the coal production process under the coal mine, an inclined shaft is undertaken the service hoisting task of different branches level, such as the lifting to material, spoil, equipment, personnel etc., when inclined shaft passes design branch level, the parking lot of uncoupling is set be used for connecting pit shaft and the large lane of design level.When the oblique crossing that is thus lifted to the parking lot of uncoupling when mine car is located to the section of flattening tunnel, because the lead of pit shaft hoisting cable and mine car running orbit in orbit are not point-blank, often can draw the shipping accidents such as bogie truck off-road, rollover.Prior art is the repetition test haulage speed of adjusting roadway floor track and the mine car problem that overcomes bogie truck off-road at the scene, realizes the mine car smooth running, and existing wastes time and energy and the many problems of artificial hidden danger.
Summary of the invention
The invention provides a kind of inclined shaft fork field of uncoupling, solved easy the sliding down and the technical matters of rollover accident during the operation of parking lot of uncoupling in the connection pit shaft of traction mine car under coal mine and the large lane of level.
The present invention solves above technical matters by the following technical programs:
A kind of inclined shaft fork field of uncoupling, comprise the inclined shaft cylinder, uncouple the fork tunnel, mine car and car haul steel rope, be provided with fork track switch and mine car transition arc turnout in the tunnel in inclined shaft cylinder and being connected of fork tunnel of uncoupling, one end of fork track switch is connected with the tramroad in the inclined shaft cylinder, the other end of fork track switch is connected with an end on mine car transition arc turnout, the other end on mine car transition arc turnout is connected the frog angle α 1 that diverges track switch with the tramroad of fork in the tunnel of uncoupling, the radian measure alpha 2 of mine car turnout transition arc track, angle β between inclined shaft cylinder and the horizontal surface and uncouple the fork ground surface in tunnel 5 and the angle δ between the horizontal surface should satisfy following relational expression:
δ＝k×arcsin〔tan10×cosβ
1〕；
β
1＝arcsin〔cos(α
1+α
2)×sinβ〕；
Wherein, k is constant, usually gets 0.6 to 0.8.
The central axis of inclined shaft cylinder with the angle α of the central axis in the fork tunnel of uncoupling is and the frog angle α that diverges track switch
1Radian measure alpha with mine car turnout transition arc track
2And equate.Included angle between the axis in car haul steel rope and the fork tunnel of uncoupling changes.
By restriction α
1And α
2, slide down and turn on one's side when simultaneously δ being adjusted to prevent the mine car operation.Be not less than mining No. 4 fork track switch and limit α by selecting
1, and make α be not more than 30 ° to limit α
2
The present invention has overcome and has promoted the traction mine car in the inside slope fork difficult problem that the field slides down easily of uncoupling, and has improved the raising efficiency of mine car, has improved the safe operation coefficient of mine car on the inside slope fork is uncoupled the field.
