Embodiment Construction

[0012] As shown in the drawings, a crane anti-collision buffer braking device mainly includes a ram 4, an elastic device, a link mechanism 3 and a braking mechanism. The ram 4 is slidably mounted on the car body 1 of the crane and extends out of the car body 1, wherein, as a conventional design, a sliding sleeve 6 is fixedly installed on the car body 1, and the ram 4 is slidably installed in the sliding sleeve 6 The elastic device is installed between the car body 1 and the bumper 4, the elastic device is preferably a compression spring 5, the compression spring 5 is sleeved in the sliding sleeve 6 and clamped between the car body 1 and the bumper between the rods 4; the brake mechanism is used to brake the traveling wheel 2 of the crane; On the rod 4, the other end is hinged on the brake mechanism.

[0013] The link mechanism 3 mainly includes a first link 31 and a second link 32 . Wherein, the first connecting rod 31 is hinged on the striker 4; the second connecting rod 32...

Abstract

The invention discloses an anti-collision buffer brake device for a crane, which belongs to the technical field of cranes and mainly comprises a sinker bar, an elastic device, a connecting rod mechanism and a brake mechanism, wherein the sinker bar is mounted on a vehicle body of the crane in a sliding manner and extends out of the vehicle body, the elastic device is mounted between the vehicle body and the sinker bar, the brake mechanism is used for braking a travelling wheel of the crane, the connecting rod mechanism is used for connecting the sinker bar with the brake mechanism, one end of the connecting rod mechanism is hinged on the sinker bar, and the other end is hinged on the brake mechanism. The anti-collision buffer brake device for the crane can convert the collision energy to the action force of the brake mechanism, avoid the impacts caused by the collision of a travelling vehicle of the crane and improve the safety performance of the crane.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane anti-collision buffer braking device. Background technique [0002] Crane buffering is an important safety protection measure for hoisting machinery. Especially in the period of rapid technological development, the types of cranes are constantly being updated. Some cranes are equipped with two parallel-operating trolleys. , even if there is a brake to reduce the speed of the traveling vehicle, due to the huge inertial force, the two traveling vehicles will collide together. At present, the commonly used buffer device is a polyurethane buffer. Although it can absorb part of the collision energy, it will still have a huge impact on the two trolleys, and its buffer effect is not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crane anti-collision buffer braking device, which can convert the energy of col...
