Synchronous wheel driven elevator damping rail clamping device

Abstract

The invention provides a synchronous wheel driven elevator damping rail clamping device. The synchronous wheel driven elevator damping rail clamping device comprises a rail clamping device shell, a clamping mechanism, a transmission mechanism, a driving mechanism, a limiting switch and a control circuit board; the rail clamping device shell comprises a groove-shaped folded plate and three side plates which are used for closing the groove-shaped folded plate; two symmetrical rectangular through hole slideways are formed at the middle position of a front side plate of the groove-shaped folded plate; the clamping mechanism comprises two clamping guide blocks; the two clamping guide blocks are arranged on the outer sides of the two rectangular through hole slideways; the bottoms of the two clamping guide blocks are connected with the transmission mechanism arranged on the back sides of the rectangular through slideways; the transmission mechanism can drive the two clamping guide blocks tomove horizontally in the two rectangular through hole slideways; the driving mechanism is fixedly arranged on the back side of the front side plate through a supporting base; the driving mechanism isin transmission connection with the transmission mechanism; the limiting switch is arranged above the transmission mechanism and is used for limiting the horizontal movement distance of the clamping guide blocks; the limiting switch and the driving mechanism are electrically connected with the control circuit board; and the synchronous wheel driven elevator damping rail clamping device has the advantages of light weight, compact design, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of manufacturing elevator safety components, in particular to an elevator damping rail clamp driven by a synchronous wheel. Background technique [0002] The rail clamp is a braking device that prevents the elevator car from accidentally moving when the door is opened. It is installed on both sides of the elevator car. Under normal conditions, when the elevator is running normally, the device does not work; when the elevator car is in the door-opening and stopping state, due to some fault in the elevator, the elevator runs unexpectedly, causing danger to passengers or goods entering or leaving the elevator. , the device acts and clamps the guide rail, thereby stopping the running elevator car to ensure the safety of passengers and goods. [0003] The patent with the existing notification number CN201310498779.X discloses a combined elevator rail clamp. The combined elevator rail clamp includes two mounting ...
