Detailed Description

The following further describes a specific embodiment of the elevator guide shoe of the present invention with reference to the accompanying drawings.

As shown in fig. 1-4, an elevator guide shoe comprises a shoe body, a guide groove 16 for accommodating a guide rail is arranged on the shoe body, the shoe body comprises a guide shoe seat 1 and a shoe lining 13, a fixing seat 15 for installing the guide shoe is arranged at the bottom of the shoe body, the shoe body is connected with the fixing seat 15 through a reinforcing rib 14, a containing cavity 12 is respectively arranged on a guide surface of the shoe body, a first clamping block 3a and a second clamping block 3b are respectively arranged in the containing cavity 12, the two clamping blocks are oppositely arranged, and a manual driving device for simultaneously driving the two clamping blocks to oppositely move is further arranged on the two clamping blocks.

The clamping block in the embodiment is in a strip-shaped structure, one end of the clamping block is a fixed end and is installed in the accommodating cavity 12 through the rotating shaft 5, the other end of the clamping block is a movable end and moves oppositely under the pushing of the manual driving device, and the clamping block clamps the guide rail and forms a wedge-shaped included angle with the guide rail so as to increase the clamping force of the clamping block on the guide rail. The guide surface of the movable end of the clamping block is provided with a chamfer so as to properly reduce the pressure when the movable end clamps the guide rail, reduce the abrasion of the clamping block and the guide rail and prolong the service life. In addition, still be equipped with on the clamp splice spigot surface and prevent pressing layer 4 to prevent the damage to the guide rail when the clamp splice compresses tightly the guide rail, prevent that pressing layer 4 is elastic material.

The manual driving device comprises a driving rod 2 and a transmission rod 6 which are in linkage action, and one ends of the driving rod 2 and one end of the transmission rod 6 respectively penetrate through the shoe body and are fixed with the two clamping blocks. The driving rod 2 is a straight rod, and the driving rod 2 penetrates through the boot body to be in threaded fit connection with the boot body so as to enhance the connection stability of the driving rod 2 and the boot body; the transmission rod 6 is of a C-shaped structure, and the other end of the transmission rod 6 is connected to the driving rod 2 in a threaded mode. Specifically, the end of the driving rod 2 connected to the transmission rod 6 is provided with a connector 11, a threaded hole for the driving rod 2 to penetrate is formed in the connector 11, and the connector 11 and the driving rod 2 are connected in a threaded fit mode to achieve linkage. When the driving rod 2 drives the first clamping block 3a to move relative to the second clamping block 3b, the driving rod 6 rotates on the driving rod 2 in a threaded mode and pushes the second clamping block 3b to move relative to the first clamping block 3a in the opposite direction.

In addition, the detection switch 8 that detects whether the clamp splice moves in opposite directions is installed to the top of the boots body, is equipped with the trigger device who triggers detection switch 8 action on the actuating lever 2, and the trigger device in this embodiment is the ring flange 9 of fixed setting on actuating lever 2, and when actuating lever 2 and transfer line 6 linkage promoted the clamp splice and moved in opposite directions, actuating lever 2 drove ring flange 9 and triggers detection switch 8 action.
