Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings.

As shown in fig. 1 and 2, it is a specific embodiment of the end braking structure of the truss robot of the present invention. This embodiment includes crossbeam 1 and sets up the support 2 that traverses on crossbeam 1 through the track slidable, crossbeam 1 is provided with arrestment mechanism 3 at both ends, arrestment mechanism 3 includes buffer block 31 and buffering strip 32, buffer block 31 and buffering strip 32 are elastic material and make, buffer block 31 sets up and is used for the buffering support 2 that traverses in crossbeam 1 tip and form the take the altitude and traverse support 2 relatively, buffering strip 32 sets up in buffer block 31 the place ahead and the upper surface forms preceding low high domatic 4 in back along length direction, domatic 4 supplies to traverse support 2's bottom surface to increase the height gradually when it removes and carry out the friction cushioning.

The utility model discloses when using, buffer block 31 and buffering strip 32 set gradually by outer to interior at the tip of crossbeam 1, move when the tip at the support 2 of transversing, 2 bottom surfaces of the support of transversing can contact domatic 4 of buffering strip 32 in advance, and then slow down through the friction, rely on the high state in 4 preceding low backs, the pressure that 2 bottom surfaces of the support of transversing were contradicted is more and more big, and make frictional resistance also more and more big because the extrusion of structure, and then reach good effect of slowing down gradually, this state of slowing down gradually provides good buffering effect, slow down the inertial force that all parts received on the support 2 of transversing and above that, speed has been lower after the buffering strip 32 in the support 2 activity of transversing, finally, stop when conflict buffer block 31, thereby realized that the braking at crossbeam 1 end is spacing. The utility model discloses a buffer structure of complex nature reaches the gradual braking and stops the effect of the support 2 that traverses, makes whole impact force reduce to support 2 that traverses carries out good spacing, improve equipment's security and durability.

As a modified embodiment, a step rack 41 is arranged on the slope surface 4 from low to high, and each tooth of the step rack 41 forms a strip-shaped buffer section for blocking the bottom surface of the traversing bracket 2 corresponding to the height of the tooth.

As shown in fig. 2, the arrangement of the stepped rack 41 enables each strip-shaped buffer section with a certain width to generate a buffer offset of a primary force when the traverse bracket 2 moves and contacts, and provides a larger friction force during the continuous movement of the traverse bracket 2, thereby comprehensively improving the buffer deceleration effect.
