Description

Technical Field

[0001] The utility model belongs to the technical field of mining machinery and relates to a hydraulic lifting type self-detachable movable track. Background Art

[0002] Waterproof gates are the main safety facilities for underground waterproofing. For mines with serious flood threats, waterproof gates should be set up at appropriate locations in the design and layout of underground tunnels. When floods occur, timely closing of waterproof gates can isolate the mine, reduce the scope of the disaster, control the water potential hazards, and ensure the safety of the mine. However, in a chamber with tracks, closing the waterproof gates is not an easy task. The active track needs to be removed before closing the waterproof gates. At present, the active track in the mine is generally removed manually on site. When double-track tracks are set in the chamber, the workload will double. When the water level rises above the track surface, manual removal will be very difficult. When the amount of water inrush is large, workers cannot reach the site to carry out the removal work, resulting in the gate cannot be closed. In addition, manual removal of the active track requires the cooperation of several people, with high labor intensity and long working hours, which can no longer meet the requirements of modern mining production.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2As shown, a hydraulic lifting self-detachable movable track includes a track body, a hydraulic cylinder 1 and a frame 2. The two ends of the hydraulic cylinder 1 are respectively hinged to the frame 2 and the middle of the track body, and one end of the track body is hinged to the top of the frame 2; the track body includes a turning frame 31 and two steel rails 32 fixed on the turning frame 31, each steel rail 32 is fixed to the turning frame 31 through a plurality of rail pressers 33, and a cover plate 34 is also fixed on the top of the turning frame 31 between the two steel rails 32. In this movable track, its hydraulic cylinder 1 can move the track body before the waterproof gate needs to be closed, so that the waterproof gate can be closed smoothly without manual removal, thereby achieving the effect of automatic and rapid removal. After the waterproof gate is reopened, it only needs to be lowered again by the hydraulic cylinder 1, so that the mine car can pass smoothly. The hydraulic cylinder 1 is driven by a hydraulic station with a pressure of not less than 16MPa. Its end seat is hinged to the middle of the track body, and the tail seat is hinged to the frame 2. The steel rails 32 on the movable track are of the same type as the chamber rails 32, and the connecting part between the movable track and the fixed track is made into an inclined surface so that the movable track does not interfere with the fixed track when it is lifted or lowered. A cover plate 34 is laid between the two steel rails 32, which can not only facilitate people to walk, but also prevent debris from falling under the track, thereby affecting its normal movement.

[0016] like Figure 3 As shown, a cylinder support 21 is fixed on the frame 2, and a double-axle cylinder 22 is fixed on the cylinder support 21; a column 23 is fixed on each push rod of the double-axle cylinder 22; a slide rod 24 and a guide rail 25 are fixed on the frame 2, and the upper end of each column 23 is sleeved with the slide rod 24, and the lower end of each column 23 is slidably connected with the guide rail 25; when the push rods of the double-axle cylinder 22 are extended, the two columns 23 just support the bottom of one end of the two rails 32 respectively. Before the track body is raised, the double-axle cylinder 22 can drive the two columns 23 to retract at the same time, and the track body can be slowly lifted by the hydraulic cylinder 1; when the track body is lowered, the two columns 23 are extended again at the same time and just support the lower end of the track body to prevent it from moving when the mine car passes.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, the frame 2 is equipped with a first proximity switch 41, a second proximity switch 42, a third proximity switch 43, a fourth proximity switch 44 and an angle sensor 45. The first proximity switch 41 is used to detect whether the track body is lowered into place, the second proximity switch 42 is used to detect whether the track body is lifted into place, the third proximity switch 43 and the fourth proximity switch 44 are used to detect the position of the measuring column 23, and the angle sensor 45 is arranged near the hinge axis between the track body and the frame 2, and the angle sensor 45 can detect the turning angle of the track body; the frame 2 is provided with a cover plate 26 above the third sensor and the fourth sensor. One end of the track body is hinged on the frame 2, so when the hydraulic oil cylinder 1 is extended, one end of it turns up, and the other end must turn down, and then slowly moves to the second proximity switch 42, so that it receives a signal, and then detects that the movable track has been dismantled (turned up into place); similarly, when the hydraulic oil cylinder 1 retracts, the movement directions of the two ends of the hydraulic oil cylinder 1 are reversed, so that the first proximity switch 41 receives a signal, and then detects that the movable track has been restored into place. The movable track is also equipped with a PLC control system, which can automatically control the action of the double-axle oil cylinder 22 according to the signals of the first proximity switch 41 and the second proximity switch 42, so that when the track body needs to be flipped up and removed, the two columns 23 are automatically retracted to avoid affecting its swing; and when the track body is reset, the two columns 23 return to their original positions to support the track body.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
