Problems solved by technology
[0002] At present, elevator safety protection devices mainly include upward overspeed protection, safety gear and rope clamp. Most of these devices use friction to stop the elevator car within a certain distance. During the normal process of entering and exiting or loading and unloading goods, due to the failure of some electrical components of the elevator or a component of the traction braking system, the car may accidentally move away from the landing, causing serious problems in the use of the elevator. security risks

Embodiment Construction
[0013] Such as Figure 1-3 As shown, an elevator rope grab includes a fixed splint 2 fixed on the machine base 1 and a movable splint 4 slidingly connected to the fixed splint 2 through the guide post 3, and the movable splint 4 is installed between the movable splint 4 and the machine base 1 to maintain the movable splint. 4 moves towards the spring 5 of the fixed splint 2 trend.
[0014] In the present invention, a swing rod 6 that can swing up and down is installed on the base 1. The swing rod 6 has a hook that can hook the movable splint 4 and keep a certain distance away from the fixed splint 2. Rod 6 is used as the driving device that unhooks movable splint 4 and swings. Concretely, the swing bar 6 can be installed on the machine base 1 behind the moving splint 4 through a transverse shaft 7, the rear side of the moving splint 4 is fixed with a hook plate 8, and the hook portion of the swing bar 6 can hook the hook plate 8, so that The rope grab remains open. When the...

The invention discloses elevator rope holding equipment. The elevator rope holding equipment comprises a fixed clamping plate and a movable clamping plate, wherein the fixed clamping plate is fixed on a motor base, and the movable clamping plate is slidingly connected with the fixed clamping plate through a guide pillar; a spring used for maintaining the tendency of enabling the movable clamping plate to move to the fixed clamping plate is arranged between the movable clamping plate and the motor base, and a swing rod, capable of hooking the movable clamping plate to keep the movable clamping plate being apart from the fixed clamping plate for a certain distance, of the hook portion is arranged between the movable clamping plate and the motor base; a driving device used for driving the swing rod to relieve the motion that the movable clamping plate is hooked to swing is arranged on the motor base, and a push rod used for pushing the movable clamping plate to move apart from the fixed clamping plate is arranged on the motor base, and the push rod is connected with the fixed clamping plate in a threaded mode; and a driven gear circumferentially fixed and connected in the axial direction is arranged on the push rod, the driven gear is engaged with a driving gear, and the driving gear is driven by a power device to rotate. When an elevator accidently moves, a hoist rope can be clamped by the elevator rope holding equipment to stop the elevator, and an accident is avoided; and opening and restoration of the rope holding equipment can further be achieved, and manual restoration is not needed, so that maintenance of the elevator is facilitated.
Description
technical field [0001] The invention relates to the technical field of elevator safety components, in particular to a rope holding device used for stopping the elevator when the elevator moves unexpectedly. Background technique [0002] At present, elevator safety protection devices mainly include upward overspeed protection, safety gear and rope clamp. Most of these devices use friction to stop the elevator car within a certain distance. During the normal process of entering and exiting or loading and unloading goods, due to the failure of some electrical components of the elevator or a component of the traction braking system, the car may accidentally move away from the landing, causing serious problems in the use of the elevator. security risks. Therefore, it is necessary to develop a device that can stop the elevator when the elevator moves unexpectedly Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rope...
