Dock locking device for a transport freight vehicle and equipment including same

摘要

The device for chocking a goods transportation vehicle at a dock comprises a horizontal support (1) designed to be anchored on the ground fronting a loading dock, a horizontal platen (2) mounted slidingly on a horizontal support (1), a rear chock (3), designed to constitute a stop for the last rear wheel train of the vehicle to be chocked at the dock, the said rear chock being integral with the said platen, a front movable thrust-action chock (4), carried by the horizontal platen (2) at a distance from the rear chock (3), the said platen (2) being actuated slidingly along the support (1) between an anterior rest position and a posterior position of chocking the transportation vehicle at the dock by a motor assembly (5), which is also capable of immobilizing the platen both in anterior rest position and in the position of chocking at the dock and maintaining it in these positions, and the front thrust-action chock being able to occupy a release position, in which it is spaced apart from the trajectory of the rear wheels of the vehicle, and an active position, in which, on the one hand, it is disposed facing one of the surfaces of revolution of one of the rear wheels of the vehicle and, on the other hand, by displacement of the platen (2) toward its chocking position, it can act in thrust manner on this surface of revolution.

1. A device for chocking a goods transportation vehicle at a dock, comprising:
a horizontal support designed to be anchored on ground fronting a loading dock, a horizontal platen mounted slidingly on the horizontal support, a rear chock, designed to constitute a stop member for a last rear wheel train of the transportation vehicle to be chocked at the dock, the rear chock being connected with the platen, and a front chock, carried by the horizontal platen at a distance from the rear chock, the platen being slidable along the support between an anterior rest position and a posterior position of chocking the transportation vehicle at the dock by a motor assembly, wherein the motor assembly is capable of immobilizing the platen both in the anterior rest position and in the posterior position of chocking at the dock and maintaining the transportation vehicle in these positions, wherein the front chock includes a release position in which the front chock is spaced apart from a trajectory of a rear wheel of the last rear wheel train of the transportation vehicle, wherein the front chock includes an active position in which the front chock is disposed facing a surface of revolution of the rear wheel of the transportation vehicle and the front chock thrusts against the surface of revolution via displacement of the platen toward the posterior position of chocking, and wherein the rear chock includes a horizontal arm carried by a pivoting lever articulated by an upper end thereof with the platen, around a horizontal axis perpendicular to the direction of displacement of the platen.
