Description
Technical field
Helicopter ground handling equipment technical field is the utility model is related to, in particular to a kind of slide-type helicopter
Ground towing machine wheel.
Background technology
Helicopter landing gear is generally divided into slide-type and wheeled two kinds.Relative to wheel undercarriage, slide-type undercarriage knot
Structure is simple and reliable, and maintenance cost is low, is generally used for light helicopter.
Slide-type undercarriage is quadrilateral space truss structure, has two symmetrical ripping bars, itself does not possess ground shifting
Dynamic ability.Therefore the separately installed towing machine wheel when helicopter needs to carry out short distance traction transport, it is necessary on skid, will be straight
Moved after the jacking of the machine of liter.Therefore a kind of simple to operate, easy for installation, cheap towing machine wheel is indispensable.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How one kind is provided just
Fixed in by slide-type helicopter, simple in construction, easy to use, the ground Orly machine of the relatively low slide-type helicopter of manufacturing cost
Wheel.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of ground towing machine wheel of slide-type helicopter, it is characterised in that including rotating shaft, the both ends of the rotating shaft by
Symmetrically arranged crank is connected with wheel；Rotationally coaxial sleeve is equipped with sleeve in the rotating shaft, and the middle part of the sleeve is set
There are skid attachment means, the skid attachment means include the skid support that can be fixedly connected on helicopter skid, described
Skid support has the arc groove that can be fitted with the upper surface of helicopter skid on the side of the rotating shaft, described
Arc groove penetrates setting along perpendicular to the direction of the rotating shaft；The axial line of the wheel is equal to the car to the distance on ground
The axial line of wheel to ultimate range and the helicopter skid of the axial line of the arc groove axial line to its bottom surface distance
Sum；
Any one end of the crank away from the wheel hub is provided with for the rotating shaft to be rotated around wheel hub
Crank to above the wheel hub, the crank are set along perpendicular to the direction of the rotating shaft；One end of the sleeve is also
The retaining mechanism for being fixed on the neighbouring crank is provided with, the rotating shaft is located above the wheel hub
When, the arc groove of the skid support is in horizontality.
Using said structure, because the axial line of wheel is equal to the axial line of wheel to arc groove to the distance on ground
The ultimate range of axial line and the axial line of helicopter skid, apart from sum, so, rotating shaft are rotated around wheel shaft to its bottom surface
To wheel hub underface when, sleeve rotates around the shaft under the Action of Gravity Field of skid support, makes the arc of skid support recessed
Groove is fitted on helicopter skid down, and skid support is fixedly mounted on helicopter skid, lifts crank, former using lever
Reason makes rotating shaft rotate to the top of wheel hub around wheel hub rotating crank.In this manner it is possible to helicopter is lifted away from ground,
Meanwhile in the presence of retaining mechanism, sleeve is fixed on crank, because crank is fixedly connected with rotating shaft.So, sleeve with
Rotating shaft is just completed and interfixed, and can move helicopter with security and stability, and fortune is drawn in the short distance suitable for light helicopter
It is defeated.
Further, the skid attachment means also include being used for the carrier base for installing the skid support, the skid
Support is removably mounted on the carrier base.
Using said structure, because skid support and carrier base are detachably connected, first skid support can be fixed
On the skid of helicopter, when needing to carry in the later stage, then skid support is connected with carrier base, is easy to fast quick-mounting
Match somebody with somebody, improve the traction transport efficiency of helicopter.
Further, the skid support is provided with two journal stirrups away from the side of the arc groove；The carrier base
It is upper that there is the slot corresponding with two journal stirrups, have in the slot through setting and corresponding with the hole of the journal stirrup
Pin-and-hole；The skid support is fixed on the carrier base by the safety pin being interspersed in the hole of the pin-and-hole and journal stirrup.
So, skid support is fixed on by carrier base by the grafting can of safety pin so that the peace installation and dismantling of the two
Unload very convenient.
Further, the hole of two journal stirrups is is coaxially disposed, and length of two journal stirrups along the arc groove
Spend direction arrangement.
So, the pin-and-hole corresponding with the hole of journal stirrup only has one, a safety pin can be used to complete skid
The fixed installation of support.So that installation is more simple and efficient.
Further, also the peep hole put mutually is provided with vertical with the pin-and-hole on the carrier base.
So, the position of safety pin inserting can be observed that by the peep hole, prevents that safety pin inserting is not in place,
When avoiding lifting helicopter, one of journal stirrup, which departs from, to be caused to damage.Be advantageous to improve the security used.
Further, the safety pin is connected on the carrier base by chain.
This way it is possible to avoid safety pin drops after being taken out out of pin-and-hole.
Further, the retaining mechanism includes the pedestal being fixedly mounted on the sleeve and along parallel to the set
The direction of cylinder is installed on the locking pin on the pedestal, and the locking pin is provided with annular close to the position of the adjacent crank
Back-up ring, compression spring is provided between the annular retaining ring and the pedestal, the locking pin is connected to the adjacent song
On handle；The crank is towards being provided with the side of the retaining mechanism for the fixed locking pin hole of locking pin insertion.
So, locking pin is connected on adjacent crank by compression spring, when rotating crank, once locking pin moves
To the position of locking pin hole, in the presence of compression spring, locking pin stretches out and inserts locking pin hole, it is possible to is automatically performed lock
Tight operation.
Further, the side of the crank towards the retaining mechanism is also set up for limiting the pedestal range
Limited block, when the locking pin is inserted the locking pin hole, the pedestal is abutted on the limited block.
So, by the collective effect fixes sleeve of the limited block and locking pin, be advantageous to improve the reliability locked.Also
When can prevent from locking pin from for some reason hindering being not inserted into pin-and-hole, pedestal is carried out spacing, be advantageous to improve safety in utilization.
Further, the crank is cylinder polished rod, is provided with to be provided with the crank of the crank and is available for the crank
The connecting hole of inserting, one end of the crank are removably inserted into the connecting hole.
Further, the other end of the crank is provided with taper knob.
In summary, the utility model has and is easy to fix in slide-type helicopter, simple in construction, easy to use, manufacture
The advantages that cost is relatively low.
