Crane pulley device capable of automatically supplementing oil

Abstract

The invention relates to the technical field of cranes, and discloses a crane pulley device capable of automatically supplementing oil. The crane pulley device comprises a shell, wherein a sling is arranged above the shell, a lifting hook movably connected to the lower end of the shell, a guide wheel is arranged inside the shell, a main shaft is coupled to the center of the guide wheel, a lubricating bin is arranged on the front side of the shell, an oil injection wheel is coupled to the front part of the main shaft, a crank piston is arranged in the oil injection wheel, an oil outlet nozzle is arranged on the oil injection wheel close to the axis, a right gear of the oil injection wheel is in meshed connection with a pointer wheel, a pointer is arranged on the front side of the pointer wheel, and a dial plate is arranged on the front side of the shell corresponding to the pointer. According to the crane pulley device capable of automatically supplementing oil, when a pulley works, a vibration block vibrates due to insufficient lubrication, the vibration block is driven to drive a lubricating bin shell to vibrate, a ratchet wheel is shifted by a pawl, then the oil injection wheel is driven to rotate for oil injection, harmful vibration mechanical energy in work is recycled without the help of external energy, and the oil injection device is driven to inject oil, and the service life of the pulley is prolonged.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane block device capable of automatically replenishing oil. Background technique [0002] The hoisting block is a hoisting tool that cooperates with the crane unit. It has a simple structure and is easy to use. It can change the direction of the pulley and the block group pulling the steel cable many times and lift the moving object. However, due to the limited installation space and limited lubrication treatment of the inner pulley of the block, it becomes the main position for wearing the suspension wire rope during the hoisting and lifting process, and the lack of lubricating leaves in the long-term suspension operation will easily deform the inner pulley of the block and affect the operation safety. The main countermeasure is regular maintenance and replacement, but because it is not the main part of the crane, it is easy to be missed, so the safety hazard is relatively hi...

However, due to the limited installation space and limited lubrication treatment of the inner pulley of the block, it becomes the main position for wearing the suspension wire rope during the hoisting and lifting process, and the lack of lubricating leaves in the long-term suspension operation will easily deform the inner pulley of the block and affect the operation safety. The main countermeasure is regular maintenance and replacement, but because it is not the main part of the lifting crane, it is easy to be missed, so the safety hazard is relatively high
