Monorail crane stretches ladder device.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of monorail crane stretches ladder device,
Including stent, telescopic device and ladder；The stent includes horizon bar and the portal trestle fixed with horizon bar；The flexible dress
Put upper end to fix with stent, lower end is fixedly connected with ladder, drives ladder to slide up and down along portal trestle.
Preferably, the portal trestle both sides frame body opposite side is respectively equipped with sliding groove, and the ladder is arranged at sliding groove
It is interior and can be slided up and down in sliding groove.
Preferably, the telescopic device includes the shaft being rotatably connected with door shaped stent, and described shaft one end sets and shakes
, the shaft is fixedly connected with the first rocking arm, the first rocking arm is rotatably connected the second rocking arm, and the second rocking arm can turn with ladder upper end
Dynamic connection.
Preferably, the shaft is connected with door shaped stent by limit spring.
Preferably, the ladder bottom sets pedal.
Preferably, stent both sides frame body sets handrail respectively.The utility model has following have compared with prior art
Beneficial effect：
On the basis of monorail crane driver's cabin is not changed, use can be mounted directly；Ensure that operation driver is easy for going up and down
In the case of, realize extension ladder automatic control, ladder can freely be stretched out, smoothly withdrawn.
Brief description of the drawings
Fig. 1 is a kind of monorail crane extension ladder apparatus structure schematic diagram.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail, below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
Stretch ladder device, including stent 1, telescopic device 3 and ladder 2 for a kind of monorail crane as shown in Figure 1；Stent 1 includes
Horizon bar 11 and the portal trestle 12 fixed with horizon bar 11；3 upper end of telescopic device is fixed with stent 1, and lower end is fixed with ladder 2
Connection, drives ladder 2 to be slided up and down along portal trestle 12.This monorail crane ladder device that stretches is installed on the left side of operating room, water
Flat bar 11 is equipped with the connecting hole 13 being fixedly connected with monorail crane, and driver is when getting on the bus for operation, pulls with hand 2 lower end of ladder, stretches
Compression apparatus 3 extends, and ladder 2 moves down, and operating personnel can enter operating room by climbing ladder 2.
As preferred embodiment, 12 both sides frame body opposite side of portal trestle is respectively equipped with sliding groove 21, and ladder 2 is set
It can slide up and down in sliding groove 21 and in sliding groove 21.Using this programme, by setting sliding groove 21, ensure that ladder 2 is slided
Stability when dynamic.
As preferred embodiment, telescopic device 3 includes the shaft 31 being rotatably connected with door shaped stent 12, shaft one
End sets crank 32, and shaft 31 is fixedly connected with the first rocking arm 33, and the first rocking arm 33 is rotatably connected the second rocking arm 34, the second rocking arm
34 are connected with 2 upper end of ladder by connecting pin 36 and connector sleeve 35.It is made up of the first rocking arm 33 of setting and the second rocking arm 34
Link rocking arm, and control ladder 2 moves up and down.
As preferred embodiment, shaft 31 is connected with door shaped stent 12 by limit spring 4.By setting spacing bullet
Spring 4, ensures ladder in minimum point and during peak, and spring 4 is all in tensioning state, when preventing that ladder is in high point, ladder 2 by
In dead weight slide downward.
As preferred embodiment, 2 bottom of ladder sets pedal 22.By setting pedal 22, on personnel easy to operation
