Background technology
Elevator cage door toeguard is generally mounted to car floor enabling side, when car is run up suddenly in level position, car
It is generated between landing sill when can make layer passenger entering into the danger in elevator shaft gap outdoors, in order to avoid person wound occurs
It is harmful, foot protecting plate device should be installed under national regulations elevator cage door sill, the vertical protection height of the foot protecting plate device is no less than
0.75m answers inclined-plane to extend downwardly below vertical component, and inclined-plane angle with horizontal plane is no less than 60 °, throwing of the inclined-plane in horizontal plane
Shadow is no less than 20mm.In order to meet national regulations, when normal elevator is checked and accepted, elevator pit depth can never be shallower than 0.79m,
But many building elevator shafts are restricted by each factor at present, can not be deep-cut pit, but must be tested by national standard
It receives, therefore, occurring can be with the toeguard of folding retractable.
Once toeguard is designed as can be with folding telescopic, may result in toeguard insufficient strength, (national regulations are scalable
Toeguard should have enough mechanical strengths：Toeguard is acted perpendicularly to out of hoistway extroversion hoistway in direction with the power of 300N
Any point on, and be evenly distributed in 5cm2Round or rectangular area on, toeguard is without permanent deformation, the change of horizontal direction
Shape should not exceed 35mm), therefore, it is necessary to carry out Design of Reinforcement to folding telescopic toeguard.
Invention content
The present invention provides a kind of foot protecting plate devices of reinforcing, and foot protecting plate device performance is made to meet national standard, maximum journey
Degree ground reduces operation and the maintenance risk of elevator under shallow pit operating mode.
A kind of foot protecting plate device of reinforcing, including：At least two-stage shield shunk on sill and slidably or be unfolded
Sole is additionally provided with reinforced liner, and one end and the cage bottom or sill of the reinforced liner are rotatablely connected, the other end and toeguard
