Miniature narrow gage single switch

Abstract

The invention relates to micro type narrow rail single turned track switch, which comprises a straight basic rail and a curved basic rail; one side of the straight basic rail is disposed with a tongue rail which is connected with an outer curved rail through the curved connecting rail and the frog; the straight basic rail is disposed with a straight guard rail which is fixed on a two-hole backing plate; one side of the curved basic rail is disposed with a tongue rail which is connected with an outer straight rail through the straight connecting rail and the frog; the curved basic rail is disposed with a curved guard rail which is fixed on a two-hole backing plate; the two tongue rails are connected by a connecting rod; the connection points of the two tongue rails with the straight connection rail and the curved connection rail are connected with straight basic rail and the curved basic rail respectively through an interval iron; and the interval iron is fixed on a stepping backing plate. The beneficial effect of the invention is that: it is especially suitable for small inclined tunnels in the mining area in mine narrow rail transportation system or other narrow occasion with limited space in mounting place.

Description

technical field [0001] The invention relates to a miniature narrow-gauge single switch. Background technique [0002] In the mining area of ​​the mine, because local areas are restricted by many factors such as ventilation, gas and geological conditions, most of the on-site roadways are designed to turn at right angles. In the case of diffuse ventilation in the small winch chamber, according to Article 132 of the "Coal Mine Safety Regulations" : The depth must not be greater than 6 meters, so that the installation size of the winch conflicts with the roadway layout; according to the coal industry standard, the minimum size of the standard single turnout is No. 2 turnout, the frog angle is 28°04′20″, and the total length of the turnout is L= 3.5 meters, due to the influence of frog angle and other factors, the laying length is too long, which is not suitable for the internal roadway conditions in the mining area. Simple turnouts have been used on site. It is characterized by ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a miniaturized narrow-gauge single-open turnout to overcome the excessively large turning angle of the switch rail, many hard turns of the turnout, no guard rails, no frogs, the road tip is not tightly bonded, and the vehicle is easy to fall. The simple turnout can only be moved by the way of manually moving the tip of the track. The manual way of switching the track has a lot of work intensity, many unsafe factors, and it is not suitable for the development needs of mine automation.
