For example: first joint portion can be including setting up the fixture block on first bracing piece 2, and corresponding second of first connecting rod 3 is held and is formed with the draw-in groove with the fixture block joint. Or, the first clamping part comprises a clamping groove 6 formed on the first support rod 2, and a clamping block 301 clamped with the clamping groove 6 is arranged at the second end of the first connecting rod 3; further preferably, the tail end of the side wall of the clamping groove 6 facing the front end of the mounting plate 1 protrudes towards the other side wall to form a protrusion 601, so that after the fixture block 301 is clamped in the clamping groove 6, the protrusion 601 can prevent the fixture block 301 from falling out of the clamping groove 6; after the transported vehicle moves to one side away from the mounting plate 1, the fixture block 301 falls off from the clamping groove 6, so that the first support rod 2 rotates towards the mounting plate 1, and the first support rod 2 cannot abut against the wheels or the track of the transported vehicle.
Specifically, the preset included angle may be any included angle that the rear end of the first support rod 2 abuts against the wheels or the track of the transported vehicle, for example, the first included angle may be an angle smaller than 45 °. Preferably, reasonable length and/or the position of first joint portion on first bracing piece 2 that sets up first connecting rod 3 can adjust the size of predetermineeing the contained angle to make after being supported first bracing piece 2 by haulage vehicle's wheel or track, first connecting rod 3 receives the pressure of first bracing piece 2, in order to avoid the rear end perk of mounting panel 1.
The working process of the slip stopper provided by the embodiment is as follows: after being hoisted or driven onto the flat plate 14 by a transport vehicle, the first support rod 2 is pulled, and the second end of the first connecting rod 3 is clamped on the first clamping part on the first support rod 2, so that the first support rod 2 and the mounting plate 1 form a preset included angle; the wheels or tracks of the transported vehicle abut against the rear end of the first support bar 2, thereby preventing the transported vehicle from moving relative to the platform 14 during transportation. When the anti-skid device is not used or other goods except vehicles are transported, the second end of the first connecting rod 3 can be separated from the first clamping part, and then the first supporting rod 2 rotates towards the mounting plate 1, so that the height of the anti-skid device is reduced, and the space occupied by the anti-skid device is reduced.
In the anti-slip device provided by the embodiment, the front end of the first support rod 2 is hinged with the front end of the mounting plate 1, the first clamping portion is arranged on the first support rod 2, the first end of the first connecting rod 3 is rotatably connected with the rear end of the mounting plate 1, and the second end of the first connecting rod 3 is used for being clamped with the first clamping portion, so that the first support rod 2 and the mounting plate 1 form a preset included angle; when the railway freight car transports goods except vehicles, the first clamping portion can be separated from the first connecting rod 3, the first supporting rod 2 rotates towards the mounting plate 1, the height of the slip stopper is reduced, and the space occupied by the slip stopper is reduced.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
