Abstract

The invention discloses a turnout device for a monorail crane in a coal mine and a moving method of the turnout device, and belongs to facilities in the coal mine. The turnout device comprises a frame, a swing rail, an inlet rail and an outlet rail, wherein one end of the swing rail is connected with the frame via a bearing, and the other end of the swing rail is arranged on a slide way and driven by an air cylinder to swing. The turnout device is characterized in that the slide way is arc-shaped, and the swing rail is arranged on the slide way via the bearing. A crank arm is enabled to act via extension of the air cylinder, the swing rail is driven to swing in reciprocation, a swing end of the swing rail is driven to roll in reciprocation on the slide rail under the action of the bearing, and the swing end of the swing rail is locked by a locking mechanism when swinging to a position in butt connection with the inlet rail, thus automatic rail changing via craning two rails by a monorail is realized. A sliding fulcrum is in a rolling mode, so that turnout direction can be changed freely.

The specific embodiment

Embodiment one: Fig. 1, shown in Figure 2, present embodiment comprises framework 33, swings rail 12, enters the orbit 19, derailed 14, swing an end of rail 12 by bearing connecting frame 33, the other end is arranged on the slideway 34 by bearing 26 and the driving by cylinder 9 swings, and described slideway 34 is arc.

Described framework 33 is ladder-shaped frame, welds hanger on the framework 33, and hanger is connected with the mine laneway anchor pole by suspension ring; Reinforcing rib (being short beam 31 and long beam 32) is set on the framework 33.

The cylinder jacket of cylinder 9 one ends is installed on the short beam 31 of framework 33, and the piston rod of the other end is connected with 5 the end of cranking arm, and 5 the centre of cranking arm is arranged on the long beam 32 of framework by bearing pin, crank arm 5 the other end with swing rail 12 and be connected.

Entering the orbit 19 has two, is separately positioned on the swing side that swings rail 12; One of them is entered the orbit and is arranged on the position that the swing starting point that swings rail connects; Another is entered the orbit and is arranged on the position that the swing terminal point that swings rail connects.

The position that the 14 swing fulcrum sides that are arranged on swing rail 12 of overstepping the limit are docked with the swing rail.Overstep the limit and be connected by transition rail 15 with the swing rail.
