Problems solved by technology

[0002] At present, the track movement mode of the turnout device for monorail cranes in coal mines uses sliding shafts and sliding fulcrums for direction change; the underground environment of coal mines has moisture, water, coal dust, corrosive gases, etc., and the sliding shafts and sliding fulcrums of turnout devices are often rusted. Orientation change cannot be performed normally

Embodiment 1

[0014] Embodiment one: figure 1 , figure 2 As shown, this embodiment includes a frame 33, a swing rail 12, a rail entry 19, and a rail exit 14. One end of the swing rail 12 is connected to the frame 33 through a bearing, and the other end is arranged on a slideway 34 through a bearing 26 and driven by the cylinder 9 to swing , the slideway 34 is arc-shaped.

[0015] The frame 33 is a trapezoidal frame, with lifting lugs welded on the frame 33, and the lifting lugs are connected with the mine roadway bolt through the lifting rings; the frame 33 is provided with reinforcing ribs (ie short beams 31 and long beams 32).

[0016] The cylinder liner at one end of the cylinder 9 is installed on the short beam 31 of the frame 33, and the piston rod at the other end is connected with one end of the crank arm 5. The middle of the crank arm 5 is arranged on the long beam 32 of the frame by a bearing pin. The other end is connected with the swing rail 12 .

[0017] There are two entry ...

Embodiment 2

[0021] Embodiment two: image 3 , Figure 4 As shown, the locking mechanism of the present embodiment includes a rail clamp 36, a steel strand 37, and a fixed pulley 35. And steel strand 37 is connected with swing rail 12, and when swing rail 12 swings to a side of track, the rail clamp device 36 of this side is opened, and the rail clamp device locking of the other side prevents driver's misoperation from causing crash accident to take place.

[0022] Other structures are the same as in Embodiment 1.

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.

Description

technical field [0001] The invention belongs to coal mine underground facilities, in particular to a coal mine underground monorail hoisting turnout device and a moving method thereof. Background technique [0002] At present, the track movement mode of the turnout device for monorail cranes in coal mines uses sliding shafts and sliding fulcrums for direction change; the underground environment of coal mines has moisture, water, coal dust, corrosive gases, etc., and the sliding shafts and sliding fulcrums of turnout devices are often rusted. Orientation changes cannot be performed normally. Contents of the invention [0003] In order to avoid normal direction change due to rust, the invention provides a turnout device for monorail hoisting in underground coal mines and a moving method thereof. [0004] The technical solution of the present invention is: a turnout device for monorail hoisting in coal mines, including a frame, a swing rail, rail entry, and derailment. O...
