Embodiment Construction
[0012] The present invention comprises support frame 6, and the front portion of support frame 6 is baffle plate 5, and the bottom of baffle plate 5 is made of two splints 3 that can fix rail 10, is fixed by screw 4 between splint plate 3; The arc surface 2 is consistent with the transition plate arc surface 1 which can be combined with the top surface of the rail 10 .
[0013] A spring damper 8 can be arranged above the support frame 6 , and the front of the spring damper 8 is the contact plate 7 . Before the crane slides forward and hits the baffle plate 5, it hits the contact plate 7 earlier, and the spring damper 8 can offset a part of the impact force of the crane.

The invention relates to a bumper of a track crane, which belongs to the improvement of the bumper structure of the track crane. The bumper of the track crane has simple structure, universal usage under dynamic condition and reliable braking ability. The bumper comprises a supporting frame and is structurally characterized in that the front part of the supporting frame is a baffle, the bottom of which is made of two clamp plates capable of fixing steel rails and the two clamps are fixed by bolts; a cambered surface in the front of the baffle is consistent with a cambered surface of an approachslabs capable of combining with the top surfaces of the steel rails.
Description
Technical field: [0001] The invention belongs to the improvement of the buffer block structure of the rail crane. Background technique: [0002] Rail cranes often have derailment and overturning accidents after being blown away by the wind and breaking into the end block, causing great losses. The track end stop that uses at present adopts following several: (1) iron shoes are put next to the crane wheel tread on the track. (2) A tripod or a vertical cement pier is welded on the rail surface at the end of the track. (3) The end of the track is provided with a sand tank stopper. (4) Elastic barriers are provided on the rail side of the end of the track. The first measure can only be used when the crane is stationary. The second measure can only withstand lighter shocks. The third measure covers a large area, high cost, regular sand turning, and poor reliability. The fourth measure is expensive, requires high installation requirements, and requires regular maintenance. ...
