The invention discloses a novel construction hoist transmission mechanism, and belongs to the field of hoist transmission mechanisms. The novel construction hoist transmission mechanism comprises a hoist main board, a first transmission rack, a first driving motor, a motor installing shell, a lifting back plate, a rack locking block, a pushing cylinder and a transmission pulley, wherein an installing sliding plate is fixedly installed on the front outer wall of the hoist main board, and a motor installing shell is installed on the installing sliding plate through a bottom sliding block in a sliding manner. According to the novel construction hoist transmission mechanism, a pushing air cylinder is installed inside the transmission mechanism in a matching mode, a rack locking block is installed at one end of the pushing air cylinder, and when a lifting mechanism is not used or the lifting mechanism stays at a certain height, the rack locking block can be directly pushed out by starting the pushing air cylinder to be clamped into a tooth groove of the transmission rack, and another limiting support is provided for closing a locked driving gear, so that an accident that a hoist falls due to the fact that the driving gear loses the locking force caused by an over-weighted heavy object on the hoist is avoided, and the use safety of the transmission mechanism is greatly improved.
本发明公开了一种新型施工升降机传动机构,属于升降机传动机构领域,包括升降机主板、第一传动齿条、第一驱动电机、电机安装壳、提升背板、齿条锁止块、推动气缸和传动滑轮,所述升降机主板的正面外壁上固定安装有安装滑板,且安装滑板上通过底滑块滑动安装有电机安装壳;本发明通过在内部配套安装有推动气缸,推动气缸一端安装有齿条锁止块,在该升降机构不使用时或者升降机构停留在某一高度时,可直接通过开启推动气缸将齿条锁止块推出,将其卡入传动齿条的齿槽内,为关闭锁止的驱动齿轮提供另一个限位支撑,避免由于升降机上重物过重而导致的驱动齿轮失去锁止力发生的升降机坠落的事故,大大提高了该传动机构使用的安全性。
