Technical Field

The utility model relates to a stop device that overhead traveling crane rises to rise belongs to the overhead traveling crane and rises the stop device field.

Background

The double-beam bridge crane is a crown block, and in order to ensure the safe operation of the crown block and avoid causing accidents, the crown block is provided with a lifting limiting device, so that when the lifting hook group rises to a limit position, the power supply is automatically cut off, the lifting hook group is prevented from being hoisted, and a steel wire rope is broken to cause the falling of a lifting appliance to cause accidents.

The weight limiting device is one of the ascending limiting devices, because the hook groups used for main lifting on site are different, some are totally-closed hook groups, some are semi-closed hook groups, and in the using process of the conventional weight limiting device, because the hook groups can swing easily when lifting a heavy object, the weight is directly twisted in the hook groups, the hook groups are damaged, sometimes the weight can be thrown out of the hook groups, and meanwhile, the lead wires of the weight and the steel wire ropes are easy to wind, the weight limiting device is damaged, and accidents are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a crown block weight stop device is provided, can prevent that weight lead wire and wire rope from twining, the weight hank is to the lifting hook group in, guarantees the safe and reliable of crown block operation.

in order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

A crown block heavy hammer limiting device comprises a limiting switch arranged at the upper end of a crown block, a heavy hammer hung below the limiting switch through a heavy hammer lead wire, a hook group connected below the crown block through a steel wire rope, and a steel wire rope baffle device for preventing the steel wire rope and the heavy hammer lead wire from winding, and a heavy hammer support plate arranged under the heavy hammer and arranged on the hook group through a support rod, wherein the heavy hammer support plate comprises a steel plate with a certain thickness and a reinforcing rib arranged on the lower end surface of the steel plate, a U-shaped groove which can allow the steel wire rope to pass but can not allow the heavy hammer to pass is arranged on the steel plate of the heavy hammer support plate, the steel wire rope baffle device comprises a steel wire rope baffle, a shackle which is arranged at one end, close to the steel wire rope, of the steel wire rope baffle and can allow the steel wire rope to pass through, and a steel wire rope clamp which is arranged at one end, close to the heavy hammer lead, of the steel wire rope baffle, and the steel wire rope baffle device is fixed above the heavy hammer through the steel wire rope clamp.

the utility model discloses technical scheme's further improvement lies in: two groups of steel wire rope clamps and shackles are arranged along the height direction.

The utility model discloses technical scheme's further improvement lies in: the shackle is sleeved with a rotatable rotary sleeve.

The utility model discloses technical scheme's further improvement lies in: and reinforcing ribs of the heavy hammer support plate are arranged around the periphery of the U-shaped groove.

Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:

The steel wire rope baffle device in the utility model can prevent the heavy hammer lead wire and the steel wire rope from being wound, and also can prevent the heavy hammer from throwing outside the hook group, so that the heavy hammer can not touch the heavy hammer supporting plate to cause the failure of the heavy hammer limiting device; the shackle is sleeved with a rotatable rotating sleeve, so that the friction of the steel wire rope on the shackle can be weakened, and the shackle is protected; after the steel wire rope baffle device is worn and damaged, the shackle and the steel wire rope clamp can enable the steel wire rope baffle to be conveniently detached and replaced; the U-shaped channel steel wire rope of the heavy hammer supporting plate can pass through but the heavy hammer can not pass through, so that the heavy hammer can be prevented from twisting into the lifting hook group to cause accidents.
