Abstract
The utility model discloses an automatic staircase overhauls footboard safety monitoring device, overhaul the footboard including automatic escalator, be fixed with push type control switch on the maintenance footboard below both sides support wall, push type control switch normally closed interlock is connected with warning circuit, normally open contact connects automatic escalator power control circuit, overhaul the button that the footboard lower surface sticiss push type control switch. The utility model discloses locate push type control switch and overhaul the footboard both sides to make push type control switch be in operating condition in when installation, normally closed interlock disconnection promptly, normally open contact is closed, and inserts warning circuit and staircase power control circuit respectively, makes to examine and repair the footboard fixing bolt in a single day to appear not hard up, or during footboard fracture scheduling problem, can be rapid cut off the staircase power and report to the police the suggestion.
Description
Technical field
The utility model relates to elevators field, is specifically related to a kind of escalator maintenance pedal safety monitoring assembly.
Background technology
Conveniently escalator is overhauled, escalator is provided with by one or a few escalator maintenance pedal when designing in upper and lower entrance, maintenance pedal generally uses bolt to fix or is directly intercalated on the supporting walls of staircase both sides, owing to being provided with the engine installation of escalator under maintenance pedal, once there is displacement in maintenance pedal, bolt of rear end plate loosens or pedal fracture, elevator is not cut off the electricity supply immediately, sandwiches staircase engine installation, cause casualties after easily causing user to fall.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of escalator maintenance pedal safety monitoring assembly, when staircase maintenance pedal generation abnormal condition, can cut off elevator power supply in time and send safety alarm, avoiding occurring personal casualty.
The utility model is achieved through the following technical solutions:
A kind of escalator maintenance pedal safety monitoring assembly, comprise escalator maintenance pedal, below described maintenance pedal, supported on both sides wall is fixed with pressing type control switch, described pressing type control switch normally closed interlock is connected with warning circuit, normally open contact connects escalator power control circuit, and described maintenance pedal lower surface presses the button of pressing type control switch.
The further improvement project of the utility model is that between described pressing type control switch, normally open contact is connected in series, and normally closed interlock is connected in parallel.
The further improvement project of the utility model is, described use bolt or industrial sticky cloth glue or intercalation are fixed on supporting walls.
The utility model tool has the following advantages:
One, the utility model low cost of manufacture, safety is stronger.
Two, pressing type control switch is located at maintenance pedal corner lower surface edge by the utility model, and make pressing type control switch in running order when mounted, namely normally closed interlock disconnects, normally open contact closes, and between each master cock normally closed interlock with the access warning circuit of mode parallel with one another, with mutual series system access staircase power control circuit between normally open contact, making maintenance pedal once there is the problem such as displacement or pedal fracture, staircase power supply can be stopped rapidly and carrying out alarm.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is pressing type control switch incircuit schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of escalator maintenance pedal of the utility model safety monitoring assembly, comprise escalator maintenance pedal 1, below described maintenance pedal 1, supported on both sides wall 2,3 is fixed with pressing type control switch 4, described pressing type control switch 4 normally closed interlock is connected with warning circuit, normally open contact connects escalator power control circuit, and described maintenance pedal 1 lower surface presses the button 41 of pressing type control switch 4.Between described pressing type control switch 4, normally open contact is connected in series, and is connected in parallel between normally closed interlock.Described maintenance pedal 1 uses bolt or industrial sticky cloth glue or intercalation to be fixed on supporting walls 2,3.
As shown in figs. 1 and 2, when maintenance pedal 1 is without potential safety hazard, four pressing type control switch 4 that maintenance pedal 1 four corner edge is installed are in running order, namely normally closed interlock disconnects, normally open contact closes, loosening once maintenance pedal bolt of rear end plate causes maintenance pedal to be subjected to displacement or pedal fracture, pressing type control switch normally closed interlock closes, warning circuit starts, normally open contact disconnects, staircase controls supply disconnecton, and (the present embodiment is only for one piece of access panel, if use polylith maintenance pedal, the supported on both sides wall 2 of every block maintenance pedal lower surface four corner edge, pressing type control switch is equipped with on 3, and between the normally open contact of each pressing type control switch, after series connection, connect access staircase power control circuit, access warning circuit is connected after in parallel between normally closed interlock, also a pressing type control switch respectively can be used to protect at supported on both sides wall if institute's use and maintenance tread width is less).
Claims (3)
