Description
Technical field
It the utility model is related to oil or chemicals equipment technology field of transport, and in particular to one kind rotation expanding activity
Ladder.
Background technology
Transport of the oil from grown place to area of consumption, mainly includes carried of crude oil and product oil transports.Carried of crude oil be from
Transport of the oil field to oil plant；Product oil transport is the transport from oil plant to area of consumption.Petroleum transportation mode have pipeline transportation,
Waterway transportation, railway transportation and highway transportation.Wherein, railway transportation way is important petroleum transportation approach, in addition, railway is transported
Defeated or chemicals transport pathway.
Railway transportation way need to use oil tank of train car, and after oil truck arrives at, operating personnel need slave station Delta
Operated on to oil truck, in the prior art, operating personnel pass through oil truck above and below simple autostairs, existing autostairs
It is simple in structure, it is impossible to carry out multidirectional rotation or extension, operating personnel are difficult to realize pair of autostairs and oil truck safety barrier
Standard, operating process are time-consuming and laborious.Also, there is security risk.
Utility model content
During oil tank of train car and chemicals vehicle entrucking, in order to make operating personnel arrive safe and sound oil tank from trestle work
Car, the utility model provide a kind of rotation expanding activity ladder.
The utility model adopts the following technical solution：
One kind rotation expanding activity ladder, including mounting base, mounting base are equipped with swivel base, and swivel base can be opposite
Rotated in mounting base.Two columns being arranged in parallel are fixedly connected with swivel base, column lower part is connected with pedal, pedal
The both sides of one end are hinged with two columns respectively, and compensating cylinder, the compensating cylinder other end and pedal outside are fixedly connected with the outside of column
Hinged, the pedal top is equipped with Extensible pedal, and Extensible pedal is arranged in parallel with pedal, Extensible pedal connection rectilinear movement machine
Structure, linear moving mechanism drive Extensible pedal to do reciprocating linear movement.
Diversified forms can be selected in the linear moving mechanism, as long as achieving the purpose that to realize Extensible pedal, folding and unfolding is i.e. back and forth
Can, usually select following three kinds of modes：
First, linear moving mechanism includes chain, and chain around being arranged on outside pedal one week, with pedal put down by Extensible pedal
OK, Extensible pedal is arranged on chain top, and chain is connected with sprocket wheel, and sprocket wheel is installed in support shaft, and support shaft both ends connect respectively
It is connected to reinforcing handle.Reinforcing when handle rotates drives support shaft to rotate, and support shaft band movable sprocket rotates, so as to drive chain to surround
Pedal rotates, and when chain rotates, drives Extensible pedal movement, stretching out and withdraw inwards so as to fulfill Extensible pedal.
The support shaft passes through column, and reinforcing handle is arranged on the outside of column.
2nd, the linear moving mechanism includes steel wire rope, and around being arranged on outside pedal one week, steel wire rope connects steel wire rope
Extensible pedal, Extensible pedal is parallel with pedal, and Extensible pedal is arranged on steel wire rope top, and steel wire rope is connected with winch, winch peace
Mounted in pedal one end, winch drives steel wire rope to be rotated around pedal, and steel wire rope drives Extensible pedal rectilinear movement, so as to fulfill prolonging
Stretch stretching out and withdrawing inwards for pedal.
3rd, the linear moving mechanism includes cylinder, and cylinder is arranged on pedal, and cylinder connection Extensible pedal, cylinder is stretched
Contracting drives Extensible pedal linear motion.
The column upper end is hinged with guardrail one end, and the guardrail other end is hinged with guardrail support, and guardrail support is cut with scissors with pedal
Connect.
Connection is supported with two vertically arranged guardrails on the Extensible pedal, and the support of two guardrails is connected with guardrail.
In the rotating hole opened up on the swivel base insertion mounting base.
The compensating cylinder is cylinder or hydraulic cylinder.
The pedal and Extensible pedal are equipped with anti-skid design.
The utility model can realize the movement and rotation in multiple orientation：
Swivel base can drive entirety to rotate relative to mounting base, so as to adjust the angle of autostairs, make it
It is directed at oil truck safety barrier position；When telescoping cylinder on pedal does linear telescopic movement, because being hinged with pedal, pedal surrounds
With the rotary motion of column hinge joint, so as to adjust the angle of pedal；Extensible pedal can prolong under the drive of linear moving mechanism
Elongation.
In use, after oil truck enters platform, it is living if the safety barrier on oil truck is in the upright position of autostairs
Dynamic ladder need to only carry out the rotary motion of pedal, by pedal from vertical state to horizontality；
After oil truck enters trestle work, if the safety barrier on oil truck cannot be in the upright position of autostairs, but
Have dislocation, at this moment just need to rotate autostairs, to the safety barrier position of oil truck, then carry out the rotation behaviour of pedal
Make and the extension of Extensible pedal operates, until autostairs snaps into the safety barrier on oil truck, avoid operating personnel's walking from existing
The upper arc surface of oil truck, so as to protect operating personnel safe.
The advantages of the utility model and have the beneficial effect that：
The utility model autostairs can flexibly carry out the rotation and movement in multiple orientation, easy to operate, safe.
