Specific embodiment
It is further described below in conjunction with the accompanying drawings：
The buffer protection device as shown in figure 1, a kind of rail is unloaded, it is by the horizontal feeding section that is overlapped on platform trailer 15
16th, the slope glissile segment 1 for being placed in the horizontal blanking section 17 on ground and being connected between feeding section 16 and blanking section 17 is constituted, and is slided
Section 1 and blanking 17 shape of cross sections of section are rectangle, and inside is hollow-core construction, inverted U-shaped curved bar 3 inside the glissile segment 1, curved bar 3
Top is connected by spring 7 with the inner cavity top of glissile segment 1, and the one end of curved bar 3 is connected with objective table 4 is slided, and sliding objective table 4 can edge
Longitudinal chute of the upper surface of glissile segment 1 is slided up and down, the valve piston of the small compression cylinder 5 of the other end of curved bar 3 and the bottom of glissile segment 1
6 are connected, and promote valve piston 6 to move by curved bar 3, and vertical big compression cylinder 8, the bottom of big compression cylinder 8 are provided with blanking section 17
Portion is connected by air inlet with small compression cylinder 5, and forms closing space 18, envelope in glissile segment 1 and blanking 17 junctions of section
Close space 18 and be provided with the Unidirectional air inlet valve 13 connected with ambient atmosphere, valve piston 6 is moved downward can promote big compression cylinder 8 big
Piston 9 is moved upwards, and the upper surface of big piston 9 is pressed with balancing weight 10, and the outside side wall of big compression cylinder 8 is provided with and connects with ambient atmosphere
Logical venthole 12.
The bottom of feeding section 16 is provided with the positioning hanger being fixed on device on platform trailer 15, and the bottom of big piston 9 is provided with
Prevent big piston 9 from departing from the support bar 11 of cylinder body, support bar 11 may be supported on the bottom surface in blanking section 17 during extreme position, greatly
The upper surface of piston 9 can select balancing weight 10 of different sizes, to coordinate the unloading operation of Different Weight rail 14, feeding section 16
The slope for being easy to rail about 14 is equipped with 17 outer ends of blanking section.
During unloading rail, can be used cooperatively using the utility model of varying number according to actual job condition, use number
Amount answers >=2, and is evenly distributed in the length direction of rail to be unloaded.The utility model is positioned over the side of platform trailer 15,
Positioning hanger 2 is set to catch on the edge of platform trailer 15 and fix, artificial mobile rail 14 slides to slip objective table 4, in rail 14
Under Action of Gravity Field, objective table 4 is slided along the chute slide downward on glissile segment 1, while driving curved bar 3 to promote valve piston 6 small
Moved downward in compression cylinder 5, now air compression causes pressure in the closing space 18 of glissile segment 1 and blanking 17 junctions of section
Power increases, and Unidirectional air inlet valve 13 is closed under stress, and the inner air pressure of closing space 18 persistently increases, in big compression cylinder 8
Big piston 9 upwards move, when the height of big piston 9 rises to venthole 12, compressed air is released by venthole 12, big compression cylinder
Air pressure reduces in body 8, and big piston 9 declines under the Action of Gravity Field of balancing weight 10, while sliding objective table 4 continues slide downward, band
The dynamic compressed air of valve piston 6, big piston 9 rises again, repeats previous step.By the mistake of compression-pressure release-compression repeatedly
Journey, glides to rail 14 and plays a part of buffer protection so that slides the smooth sliding of objective table 4 to blanking section 17, manually will
Rail starts to shrink at, drives and slide objective table 4 and small work from unloading on objective table 4, the spring 7 that the top of curved bar 3 is elongated is slided
Plug 6 is moved upwards along glissile segment 1, and now the inner air pressure of closing space 18 of glissile segment 1 and blanking 17 junctions of section diminishes,
Under external atmosphere pressure effect, Unidirectional air inlet valve 13 internally opens a smaller angle, and outside air enters closing space
In 18, slide after objective table 4 and valve piston 6 return to original position, you can carry out unloading operation next time.
The present apparatus of varying number can be arranged during unloading rail along platform trailer 15, the upper surface of big piston 9 can select greatly
Small different balancing weight 10, can flexible adaptation different length, the unloading operation of Different Weight rail.Using the utility model, can
Quickly and safely to unload rail from dollie, easy to use, simple structure can be prevented effectively from when rail is unloaded and rub
Wiping is collided with and damages and be broken.
