Embodiment Construction

[0009] like figure 1 , figure 2 As shown, the emergency brake of the present application is composed of two clamping arms 3 and an electric hydraulic pusher 4. The inner side of the two clamping arms 3 has a protruding part, and the protruding part has a shaft hole. The hinge shaft 3 is used to connect the two clamps The arms 3 are connected together, and the head shape of the clamping arm 3 is a tangential ring adapted to the rim of the traveling wheel 8 exposed to the outside, and the tangential surface in contact with the rim of the traveling wheel 8 has a brake pad 7, and the two An electric hydraulic pusher 4 is connected to the inner side of the tail of the clamp arm 3 , and a connecting shaft 5 is arranged at the outer side of the tail of the two clamp arms 3 , which is movably connected to the head bracket 2 of the crane end beam 1 through the connecting shaft 5 .

[0010] The electric hydraulic pusher can use the YT1-182B / 2 model produced by Henan Jiaozuo Jianghe Br...

Abstract

The invention discloses a gantry crane emergency brake, which is characterized in that the gantry crane emergency brake comprises two clipping arms and an electro-hydraulic thruster, wherein a projection is arranged on the inner sides of the two clipping arms, the projection is equipped with a shaft hole, the two clipping arms are connected together by a hinge axle, the head shape of the two clipping arms is a diathermy loop shape which is compatible to the wheel edge which is exposed outside the outer portion of a road wheel, and a brake block is arranged on a diathermy loop surface which is contacted with the wheel edge of the road wheel. The inner sides of the tail portions of the two clipping arms are connected with the electro-hydraulic thruster, the outer sides of the tail portions of the two clipping arms are equipped with a connecting shaft and are actively connected with a support which is arranged on the head portion of an end beam of a crane through the connecting shaft. Because the brake brakes rapidly, the braking frictional area is big, the road wheel is directly braked, so the brake plays a role of emergency braking.

Description

technical field [0001] The present application belongs to a gantry crane, and particularly relates to a brake of a gantry crane. Background technique [0002] At present, the braking device of the gantry crane is to set the braking wheel and the brake belt on the traveling motor shaft, and this braking method cannot meet the needs of emergency braking due to the small braking force. The gantry crane needs to be braked immediately in many emergency situations, otherwise there will be an accident, so an emergency brake is very much needed. SUMMARY OF THE INVENTION [0003] In order to solve the emergency braking problem of a gantry crane, the present application proposes an emergency brake. [0004] The emergency brake of the present application is composed of two clamp arms and an electric hydraulic pusher. The inner side of the two clamp arms has a protruding part, and the protruding part has a shaft hole. The two clamp arms are connected together by a hinge shaft. The s...
