Mechanical stopping device of elevator and reset assembly thereof

Abstract

The invention relates to a safety protection device of an elevator, in particular to the mechanical stopping device of the elevator and a reset assembly thereof. The mechanical stopping device of theelevator comprises a fixing base, a supporting rod connected onto the fixing base in a hinged mode and the reset assembly arranged on the side, close to a landing door, of the supporting rod, whereinthe reset assembly comprises a switch support installed in a well and a reset rod detachably installed on the switch support, the reset rod comprises an operating part used for driving the supportingrod to rotate to a stopping state and an insertion piece used for being matched with the switch support in an inserted mode, and the insertion piece and the switch support form a reset safety switch.When the device and the reset assembly are in use, the reset rod is taken off, the reset safety switch is disconnected, the supporting rod is driven to the stopping state through the operating part, and a safety protection switch is disconnected, so that a maintenance state is entered; when maintenance is completed, the supporting rod is put away, the safety protection switch is closed, the resetrod is put back into the switch support, and an elevator safety circuit is connected; operation is convenient, and the safety factor is high; the structure is simple, the production cost is low, and space is saved.

Description

technical field [0001] The invention relates to an elevator safety protection device, in particular to an elevator mechanical stop device and a reset assembly thereof. Background technique [0002] With the continuous development of the economy, there are more and more villas. Based on the needs of residents, more and more home elevators will be installed in villas. However, most of the elevator shafts in villas are very narrow, and the depth of the shaft pit is relatively shallow, which makes it difficult to repair the pit. In the maintenance process, it is very important to ensure the life safety of maintenance personnel. According to the requirements of GB / T21739-2008 "Manufacturing and Installation Specifications for Household Elevators", when the top floor and bottom pit space of a home elevator cannot ensure the life safety of maintenance personnel , it is necessary to install a mechanical blocking device as an auxiliary device to ensure a safe space.

AI Technical Summary

Problems solved by technology

The overall structure of the device is relatively complicated. A traction rope is set between the fixed seat and the positioning frame outside the hoistway, occupying the space outside the well, and a rope sleeve is arranged outside the traction rope. There is a problem of rope entanglement and knotting, which affects the reliability of use

In addition, if there is a failure at the support rod and the contact switch, there are still potential safety hazards in the maintenance process after personnel enter the well, and its safety guarantee needs to be improved
