Description
Technical field
The forward-reverse control device of the self-propelled upstairs going cart of the present invention, after being mainly applied to the advance of self-propelled upstairs going cart
Move back the technical of the balance correction of control switch and self-propelled upstairs going cart.
Background technology
The existing self-propelled upstairs going cart of tradition, is widely used in maintenance of works or when storage is transported goods uses, general
Most of self-propelled upstairs going cart is all that installing is in orbit, and cat ladder is equipped with the cable controller of a connection electro-motor, then profit
It is moved forward or back with the self-propelled upstairs going cart of controller manipulation and control on hand.
But in practical operation in application, must carry controller due to the use of person could control self-propelled climb
Tower wagon move forward or back, it appears it is fairly cumbersome with it is inconvenient, while controller connect electro-motor line also be easy to cause use
When person climbs up, climbs down, impeding for freedom of movement is interfered, it appears than relatively hazardous, both deposited for it and waited to overcome the problems, such as solution and lack
One of fall into.
In addition, the existing self-propelled upstairs going cart of tradition, is generally all not provided with balance correction apparatus, works as ground relief
When, can not automatic balancing correction both deposited and waited gram for it so have no idea to ensure the stationarity on self-propelled upstairs going cart and ground
Clothes solve the problems, such as two with defect.
Invention content
The present inventor is currently undertaken by the manufacture of Related product, design, practical experience and gains in depth of comprehension for many years is accumulated, for tradition
The spirit that the problem of existing self-propelled upstairs going cart is both deposited and defect energetically inputs innovation and are improved, that is completed walks certainly
The forward-reverse control device of formula upstairs going cart.
Invention solve the problems, such as the technological means that one is applied and against existing technologies the effect of one be：Car body is equipped with
One cat ladder, cat ladder upper and lower are equipped with two fixed frames, two elastic elements and a moving part, and the centre of cat ladder is equipped with a forward-reverse control
System switch, forward-reverse control switch are equipped with a box body and a lid, and box body and lid are internally provided with a variable resistance, a set of
The center of cylinder and a brake switch, variable resistance and sleeve is equipped with a shaft and an axis hole, is thus arranged and is integrally fixed, sleeve
Outside extend outwardly equipped with a moving plate, be used as moving part and the connection of the elastic element of lower section, set at the circumference of sleeve
There is a locating flange in half circle configuration, is used as keeping sleeve to be centrally positioned at motionless position, box body pair
It should be equipped with a brake switch at the flange lower section of sleeve, when pulling moving part downward or upward, you can with moving sleeve and can be changed
Resistance is rotated forward or is reversed so that the flange on sleeve can contact or not contact brake switch, while be turned using variable resistance
The variation of dynamic detection resistance, judgement user want to move forward or back, and car body forward or backward are automatically controlled, before touching
Afterwards until two position-sensing switches, after decontroling moving part, sleeve is allowed to be maintained at intermediate fixed position, that is, halt or
It retreats, seems in operation and be easier with conveniently, opposite also seems that comparison is safe；It is that it is main with the enhancement in effect
Purpose reaches winner.
