Abstract
The invention provides an oscillating rod for a mining overspeed preventing catcher for an inclined roadway, which overcomes the deficiency of a touch rod in current catchers, avoids accidents and ensures the lifting safety in the inclined roadway. According to the oscillating rod for the mining overspeed preventing catcher for the inclined roadway provided by the invention, an upper baffle is welded on the upper part of a main steel tube, a spring is sleeved on the main steel tube below the upper baffle, and a lower baffle is arranged in a normal position of the spring of a main steel tube. The upper end of a moveable sleeve reduced is welded with a retainer ring, and the lower part of the moveable sleeve is arranged in a semi-spherical shape. The oscillating rod is changed to be stretchable and moveable. When a skip car is lifted, as the tail end of the oscillating rod is semi-spherical and the contact area with the skip car is small in a point-to-point manner, the leaning probability is reduced. Even if the skip car leans against the oscillating rod, the moveable sleeve slides upward under the pressure, and the oscillating rod is shortened, so that the skip car can pass smoothly.
Description
Technical field
The present invention relates to the mine safety production field, specifically the anti-hypervelocity of a kind of mining inclined tunnel racing car device swing arm.
Background technology
At present, in the mine production operation process, anti-hypervelocity racing car device is essential, the anti-hypervelocity racing car device that uses now, swing arm mostly is hard steel pipe, and winch is in lifting process, mine car has pushed up the catcher touch pole, very easily make bogie truck off-road, touch pole flexural deformation is put forward fortune to the inclined gallery, ore deposit and is formed potential potential safety hazard.
Summary of the invention
Purpose of the present invention just provides the anti-hypervelocity of a kind of mining inclined tunnel racing car device swing arm, overcomes the defective that existing catcher touch pole exists, and avoids accident to occur, and guarantees that inclined gallery put forward the safety of fortune.
The present invention is achieved in that main steel pipe top welding overhead gage, sleeve spring on the main steel pipe under the overhead gage, and main steel pipe spring normal position arranges lower baffle plate, and back-up ring is welded in the moving casing upper end after undergauge is processed, and semisphere is arranged in the moving casing bottom.
Diameter after moving casing upper end undergauge is processed greater than main diameter of steel tube less than the lower baffle plate diameter.
The invention has the beneficial effects as follows: swing arm changes the telescopic movable formula into, and is little of point contacts with the area of contact of truck because the swing arm end is semisphere when truck promotes, so reduced the mutually probability on top.Both made mutually and pushed up, under the effect of pressure, the moving casing upward sliding, the swing arm contraction in length is so that truck passes through smoothly.
Description of drawings
Be described further below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Among the figure 1, main steel pipe, 2, moving casing, 3, overhead gage, 4, spring, 5, back-up ring, 6, lower baffle plate.
The specific embodiment
As shown in the figure, main steel pipe 1 top welding overhead gage 3, sleeve spring 4 on the main steel pipe 1 under the overhead gage 3, main steel pipe 1 spring 4 normal position arrange lower baffle plate 6, and moving casing 2 upper ends are welding back-up ring 5 after undergauge is processed, and semisphere is arranged in moving casing 2 bottoms.
When truck when withstanding swing arm, moving casing 2 is upward sliding thereupon, avoids pushing up mutually with truck, simultaneously spring 4 storages are pressed, after truck passed through, under the effect that spring 4 resets, moving casing 2 descended and returns to original position.
Claims (2)
1. a mining inclined tunnel is prevented hypervelocity racing car device swing arm, it is characterized in that, main steel pipe top welding overhead gage, sleeve spring on the main steel pipe under the overhead gage, main steel pipe spring normal position arranges lower baffle plate, back-up ring is welded in the moving casing upper end after undergauge is processed, semisphere is arranged in the moving casing bottom.
2. the anti-hypervelocity of a kind of mining inclined tunnel according to claim 1 racing car device swing arm is characterized in that, the diameter after moving casing upper end undergauge is processed greater than main diameter of steel tube less than the lower baffle plate diameter.
