Abstract
The utility model discloses a maintenance safety device for pits of knapsack frame-type small-tonnage elevators. The device comprises a buffer bracket (2) arranged on a slide-way (1) and a buffer plate (3) positioned on the buffer bracket (2). The device can prevent the accidents occurring when elevators accidentally run downwards during the maintenance. The device has simple structure and can provide reliable safety and protection for maintenance personnel when overhauling the pits of knapsack frame-type small-tonnage elevators.
Description
Technical field
The utility model relates to the maintenance fender guard that a kind of elevator is used, the little tonnage elevator pit of particularly a kind of knapsack posture maintenance safety device.
Background technology
Along with the widespread use of the little tonnage elevator of knapsack posture, often need carry out the maintenance of elevator.When service personnel entered hoistway maintenance elevator, particularly service personnel needed to guarantee the safety of service personnel when well pit is maintained.Existing way is with the elevator outage, and elevator is not moved.But it is still descending under off working state elevator to occur, such as elevator stress, situation such as, towing machine band-type brake failure state light to heavy side causes elevator because weight is walked downward greatly; Can cause serious accident.
The utility model content
The purpose of this utility model is: the little tonnage elevator pit of a kind of knapsack posture maintenance safety device is provided.This apparatus structure is simpler, can be service personnel the failure-free safety guard-safeguard is provided when the little tonnage elevator pit of knapsack posture upkeep operation.
The technical solution of the utility model: the little tonnage elevator pit of a kind of knapsack posture maintenance safety device, comprise the buffering stand that is located on the guide rail, buffering stand is provided with dash plate.
Compared with the prior art, the utility model the time can prevent that in maintenance unexpectedly having an accident when descending from appearring in elevator.The utility model structure is simpler, can be service personnel the failure-free safety guard-safeguard is provided when the little tonnage elevator pit of knapsack posture upkeep operation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Site plan when accompanying drawing 2 is the utility model use;
Being masked as in the accompanying drawing: 1-guide rail; The 2-buffering stand; The 3-dash plate; 4-elevator underbeam.
The specific embodiment
Embodiment: the little tonnage elevator pit of a kind of knapsack posture maintenance safety device comprises the buffering stand 2 that is located on the guide rail 1 as shown in Figure 1, and buffering stand 2 is provided with dash plate 3.
Elevator is closed in outage when service personnel enters the well pit maintenance, and this device is placed in position as shown in Figure 2, elevator below, and the device that moves up then makes dash plate 3 adjacent in the bottom of elevator underbeam 4, and buffering stand 2 and guide rail 1 are used bolt.It is still descending under off working state elevator to occur, such as elevator stress, situation such as, towing machine band-type brake failure state light to heavy side cause elevator since weight greatly still when descending, be fixed on the friction force that produces on the guide rail 1 by the buffering stand 2 of device and just can withstand elevator, force the elevator can't be descending.
Claims (1)
1. the little tonnage elevator pit of knapsack posture maintenance safety device, it is characterized in that: comprise the buffering stand (2) that is located on the guide rail (1), buffering stand (2) is provided with dash plate (3).
