Description
Technical field
Head carry concealed ladder and can fast braking monorail crane dolly, belong to monorail crane technical field.
Background technology
Colliery is more and more using monorail crane at present, and the security performance of monorail crane requires also more and more higher, especially exists
Require in terms of braking higher, it is desirable to which brake force is big, and retro-speed is fast, it is necessary to stop immediately can just stop, and monorail crane is braked
Must be decompression braking, that is to say, that open in damper brake when having pressure, should make at once after no pressure
Monorail crane Brake stop.But existing monorail crane braking retro-speed is slow, can not meet the requirement stopped immediately, safety
Property is poor.
It is simultaneously more using an easy movable ladder using personnel's disengaging of monorail crane head, personnel enter when
Time is hung up, and ladder is lifted down to the side for being suspended to head later up, ladder weight weight length length, takes up and down inconvenience；And
And sometimes ladder is not lifted down also and just opens monorail crane and move forward and backward, and often results in ladder or head draws bad accident.
The content of the invention
The technical problems to be solved by the invention be to provide a kind of head can convenient retracted ladder and can fast braking list
Rail hangs dolly.
In order to solve the above technical problems, the technical solution adopted in the present invention：Head carries concealed ladder and can be quick
The monorail crane dolly of braking, concealed ladder include ladder body, two fixed seats and slideway, and described two fixed seats are symmetrically solid
The bottom plate bottom surface of monorail crane head is scheduled on, and the spacing of two fixed seats is adapted with ladder body width, the slideway
The bottom plate bottom surface of monorail crane head is fixed on, and two fixed seatings are in the end of slideway；
Brake apparatus includes brake cylinder, tripping spring, card valve, a pair of round flanges and connector, and the brake cylinder includes cylinder
Cylinder, guide sleeve, guide sleeve back-up ring, piston rod, piston, spring, check ball, nonreturn valve core and one-way valve seat；
Guide sleeve is provided with by inner one end provided with piston, in outer one end of inner cavity of cylinder and guide sleeve is kept off in the inner cavity of cylinder
Circle, and guide sleeve back-up ring is located at the outside of guide sleeve, is provided with the middle part of the piston, guide sleeve and guide sleeve back-up ring with living
The hole that stopper rod gap coordinates, the piston rod are step hollow stem, and the big one end of piston rod inner diameter is provided with spring, piston
The small one end of bar inside diameter is provided with oil inlet, and piston rod be provided with spring one end in the inside of cylinder barrel, provided with oil inlet
One end is in the outside of cylinder barrel, and the piston rod sets spring one end provided with the nonreturn valve core being connected with spring one end, with the list
The one-way valve seat coordinated to valve element is threaded in piston mider hole, and through hole is provided with the middle part of one-way valve seat,
The cylinder barrel sets the oil-out that the outside of piston one end has inner cavity of cylinder to connect；
The one end for setting spring in the piston rod is provided with a step radial hole connected with oil inlet, and radial hole is straight
The small one end in footpath, away from spring, check ball is provided with the big one end of radial direction bore dia close to the big one end of spring, diameter；
A round flange is equipped with described brake cylinder cylinder bottom one end and piston rod one end, in brake cylinder outer cover equipped with system
Move spring, and round flange of the both ends of the tripping spring respectively with brake cylinder both ends is connected, connector and the card valve
Piston rod one end of brake cylinder is arranged at, and the cylindrical of card valve is cased with round flange, and the connector passes through card valve and work
Stopper rod end connects, and is provided with connector position into oilhole.
Chute protection plate is provided with outside the slideway.
The concealed ladder course of work of the present invention is：Ladder is pulled upwardly manually after driver enters driver's cabin, arrived
During up to horizontal level, enter to the slideway horizontal sliding below head.Driver need from head get off when, then manually draw
Firmly ladder end, pulled out from head bottom until ladder is all pulled out, ladder hangs down into vertical shape automatically after loosing one's grip
State, driver can smoothly get off.
The inner cavity of cylinder of brake apparatus of the present invention is divided into two parts by piston, wherein the part for having piston rod is to have
Rod cavity, a part for piston-rodless are rodless cavity, and rod chamber and rodless cavity be can lead to can be obstructed design, when rod chamber pressure
Obstructed both when power rises, hydraulic oil can be quickly from there is bar when communicating both when rod chamber pressure declines, and communicating
Chamber enters rodless cavity, realizes rod chamber quick release decompression function.Its specific work process is：As shown in Fig. 2 when hydraulic oil from
After oil inlet enters, the oilhole among piston rod enters and reaches nonreturn valve core position, because check valve is in the work of spring
Sealing state is in one-way valve seat with lower, so hydraulic oil will not flow to rodless cavity, and can only be from the footpath hole of check ball position
Flow in rod chamber, then promote piston to start to move right, piston rod drives the compression that moves right of the round flange of its end high
The tripping spring of intensity, to open damper brake；When needing brake, it is necessary to piston rod stretching quickly in the presence of external force
Open, specific action is as shown in Figure 3.When the pressure of oil inlet declines, check ball can be blocked under the pressure effect of rod chamber
Piston rod radial hole, prevent the hydraulic oil in rod chamber from being flowed out by check ball from oil inlet, and be to continue with keeping necessarily
Pressure, and pressure very little inside piston rod, therefore the nonreturn valve core meeting compression spring under the pressure effect of rod chamber hydraulic oil, and
One-way valve seat disengages, and communicates rod chamber and rodless cavity, the hydraulic oil of rod chamber rapidly flows toward rod chamber, and piston rod is in high intensity
Stretching out quickly in the presence of tripping spring thrust, makes monorail crane realize fast braking.
Compared to the prior art the present invention has the advantages that.
First, the present invention is by the way that ladder to be arranged on to the bottom plate bottom surface of monorail crane head, pulls out during use and promotes when not in use,
So not only facilitate the use of ladder, and also improve the security used without removing ladder from head, reduce ladder
The spoilage of son.On the one hand the present invention promotes pull-out to play the guiding role by setting chute protection plate for ladder, on the other hand also prevent
On-slip road and ladder can not promote pull-out after getting rusty.
2nd, the present invention is rapider compared to braking compared with monorail crane brake apparatus in technology, and work is safer.
