Abstract
The utility model discloses a pneumatic linking type car stopper which comprises a first car stopper and a second car stopper, wherein a first cylinder, a second cylinder, a first two-position three-way valve for controlling the first cylinder and a second two-position three-way valve for controlling the second cylinder are mounted in a signal cave chamber of an upper flatcar field on a track; the two two-position three-way valves are arranged on a same axial line and two valve heads are opposite to each other; a back-and-forth swinging operation rod is arranged between the two valve heads; an oil rope of the first car stopper is guided and then is connected with the first cylinder; and the oil rope of the second car stopper is guided and then is connected with the second cylinder. The pneumatic linking operation of two car stoppers in the upper flatcar field is realized according to the utility model, the promotion for the conveying safety is ensured, the automatic operation of car stopping facilities can be realized by slightly pulling an operation handle by a person, and the pneumatic linking type car stopper is safe and reliable.
Description
Technical field
The utility model relates to the stop buffer of mine rail transportation usefulness.
Background technology
Go down the hill on the track of clear: 10～200m in " mine transportation safety technical supervision standard ", when its top is the flatcar field, (be not more than 1.5m apart from grade change point) in the pittop and locate to establish the first stop buffer, be slightly larger than the place of a hook vehicle commander degree below the grade change point, installing second stop buffer, both will have and automatically reset or linkage function.The interlock of order the first two stop buffer adopts oil thread rope to connect the twice stop buffer, and oil thread rope is connected with operating handle by the track adjusting wheel guiding is rear; Manually firmly operating handle is pulled down to a side by midway location during use, the first stop buffer is in the non-state of keeping off a car, after vehicle is crossed the top stop buffer, artificial rapidly operating handle is pulled down to opposite side rapidly, the first stop buffer is in the state of keeping off a car, and the following second stop buffer of grade change point is in the non-state of keeping off a car.This operating mode is entirely by artificial rapidly operation, reliability poor stability.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides the Pneumatic linkage formula stop buffer that the upper flat parking lot of going down the hill on a kind of track is used.
The technical scheme that the utility model is taked is: a kind of Pneumatic linkage formula stop buffer, it comprises first stop buffer and second stop buffer, it is characterized in that it also is equipped with the first cylinder, the second cylinder and controls the first two-position three-way valve of the first cylinder, the second two-position three-way valve of control the second cylinder in section's flatcar field signal chamber in orbit; Two two-position three-way valves be arranged on the axis and two valve heads relative, between two valve heads, establish a control lever that swings back and forth, be connected on the first cylinder after the oil thread rope guiding of first stop buffer, be connected on the second cylinder after the oil thread rope of the second stop buffer guiding.
When without vehicle by the time, operating handle is subjected to mediate under the effect of two two-bit triplet valve springs, the piston of two cylinders stretches out, the oil thread rope pine returns, two stop buffers are risen by self gravitation to be in the position of keeping off a car.When vehicle is transferred from the pittop, operating handle to be pulled to the first two-position three-way valve one side, the first two-position three-way valve P, B mouth lead to, and cylinder piston shrinks, and the first stop buffer is in the non-state of keeping off a car.Vehicle is by behind the first stop buffer, rapidly the operator handle is pulled to the second two-position three-way valve, second valve two-bit triplet P, A mouth lead to, cylinder piston stretches out, the first stop buffer rises by deadweight, is in the state of keeping off a car, and the second two-position three-way valve P, B mouth lead to, the second cylinder piston shrinks, and the second stop buffer is in the non-state of keeping off a car under the grade change point.After vehicle passes through second stop buffer stop buffer, hand unclamp operation handle, two two-position three-way valves recover midways location.
The utility model has been realized the Pneumatic linkage operation of two stop buffers in flatcar field, pittop, has guaranteed Lifting Convey safety, and personnel only need easily pull operating handle, and the automatic operation of the facility of just can realizing keeping off a car is safe and reliable.
Description of drawings
Fig. 1 is the utility model scheme drawing.
Marginal data: 1-the first cylinder, 2-the second cylinder, 3-the first two-position three-way valve, 4-the second two-position three-way valve, 5-control lever, 6-first stop buffer, 7-second stop buffer.
The specific embodiment
As shown in the figure, Pneumatic linkage formula stop buffer of the present utility model comprises first stop buffer 6 and second stop buffer 7, it is also gone down the hill in orbit and the first cylinder 1 is installed in the signal chamber of upper flat parking lot, the second cylinder 2 and the first two-position three-way valve 3 of controlling the first cylinder 1, control the second two-position three-way valve 4 of the second cylinder 2, the first two-position three-way valve 3 be arranged on the axis with the second two-position three-way valve 4 and two valve heads relative, establish a control lever that swings back and forth 5 between two valve heads, be connected on the first cylinder 1 after the first stop buffer 6 oil thread ropes guiding, be connected on the second cylinder 2 after the oil thread rope of second stop buffer 7 guiding.
