Safety gear with easy control of synchronism

Abstract

The invention relates to a safety gear with easy control of synchronism. The safety gear comprises two car bottom framework steel channels and a middle beam, wherein the middle beam is positioned between the two car bottom framework steel channels, the middle parts of the outer walls of the two car bottom framework steel channels are respectively provided with a lifting assembly and a safety gear assembly, each lifting assembly comprises a lifting rod and a fixing plate, each fixing plate is used for further fixing the corresponding lifting rod and the corresponding car bottom framework steel channel, the two lifting assemblies are connected by a transverse rod and the middle beam in parallel, the two ends of the transverse rod are connected with two sleeve tubes, the inner diameter of each sleeve tube is the same with the outer diameter of the transverse rod, the two ends of the transverse rod are screwed into the sleeve tubes, the connecting part of the transverse rod and the corresponding sleeve tube is fixed by a first positioning pin, and the other ends of the two sleeve tubes are fixedly arranged on the lifting rods at the two sides. The safety gear has the advantages that the synchronism is guaranteed in the manufacturing process, the subsequent inspection and adjusting process is not needed, the time and labor are saved, and the large-scale production of enterprises is convenient.

Description

technical field [0001] The invention relates to a device in the technical field of forming elevator components, in particular to a safety gear that is easy to control synchronization. Background technique [0002] Among the safety components of the elevator, the safety gear is one of the more important safety components. When the elevator breaks down and the car’s descending speed reaches the action speed of the speed limiter, the speed limiter will act immediately, lift the brake elements of the safety gear on both sides of the car through the safety gear, and stop and clamp the car Hold on to the rail. Therefore, only by ensuring the safety and effectiveness of the safety gear can the safety of the elevator be guaranteed. The most important thing in the safety gear is the synchronization of the safety gear. It is necessary to ensure that the safety gear on both sides of the elevator brakes synchronously and has the same braking effect, so as to ensure that the elevator s...

Problems solved by technology

It is very troublesome to adjust the synchronization of many existing designs of safety gear after production. Not only does it require the help of test tooling equipment, but it is also difficult to adjust itself, which brings great trouble to the operator during the production process. Time-consuming and labor-intensive, the adjustment results are not ideal, and it is difficult to fully ensure that the synchronization deviation of the safety gear is within the specified range. Once this kind of safety gear is put into use, it will bring a very large safety hazard
