[0003] This type of protection device is installed on the worm to measure the torque conversion of the gate, but it is often prone to failure. When the load overload protection requirements are met during the opening and closing process, the screw machine cannot be protected. When the screw machine closes the door, the screw machine being bent over, having an accident

The invention relates to the technical field of open-close machines, in particular to a protection device for a spiral bevel gear screw-type open-close machine. The protection device for the spiral bevel gear screw-type open-close machine comprises a body and a screw, wherein a bearing nut is arranged on the body, the screw is screwed with the bearing nut, an upper guide sleeve and a lower guide sleeve are arranged at the both ends of the bearing nut respectively, the bearing nut, the upper guide sleeve and the lower guide sleeve are connected with a nut steel sleeve, an upper thrust ball bearing is arranged on the portion stretching out of the nut steel sleeve, of the upper guide sleeve, and a lower thrust ball bearing is arranged on the portion stretching out of the nut steel sleeve, of the lower guide sleeve; an upper cover plate and a lower cover plate arranged on the shell of the body, a close pressure sensor contacted with the upper thrust ball bearing is fixedly installed on the upper cover plate by a bolt, and an open pressure sensor contacted with the lower thrust ball bearing is fixedly installed on the lower cover plate by a bolt. The protection device for the spiral bevel gear screw-type open-close machine prevents the screw from being bent by jacking when the screw machine is closed.
Description
technical field [0001] The invention relates to the technical field of hoists, in particular to a protection device for a helical bevel screw type hoist. technical background [0002] At present, torque sensors and converters are generally used as protection devices for the hydraulic measuring gate opening and closing force to the screw hoist. The load overload of the screw machine is protected by measuring torque conversion, and an absolute encoder is installed on the screw machine to directly connect with the screw through gears. The absolute encoder is used to measure the lifting height of the gate and send it to the instrument for display. When the upper and lower limits are reached, the relay acts for limit protection. [0003] This type of protection device is installed on the worm to measure the torque conversion of the gate, but it is often prone to failure. When the load overload protection requirements are met during the opening and closing process, the screw mach...
