The orientation or position relationship shown, is for only for ease of the description present invention and simplifies description, rather than indicate or imply signified dress
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to present invention protection
The limitation of scope.
Harvester includes tanker, framework platform and engine, and tanker is fixed on framework platform, and engine is flat positioned at frame
On platform, and positioned at the rear portion of tanker.Fig. 1 to 3 shows the structural representation of cat ladder proposed by the present invention.The cat ladder includes cat ladder
13rd, pedal 2 and handrail.
Cat ladder 13 is installed on the framework platform of harvester.Particularly, cat ladder 13 is symmetrical structure, and it includes bottom plate
10th, cat ladder beam 7, crossbeam 9 and diamond plate 8.Bottom plate 10 is two, is mounted on the framework platform of harvester.Cat ladder beam 7 is two
It is individual, it is respectively and fixedly connected with two bottom plates 10.Crossbeam 9 is some, is fixed between two cat ladder beams 7, and deposited with the engine of harvester
In certain safe distance.Diamond plate 8 is some, is respectively and fixedly connected with some crossbeams 9, diamond plate 8 has lablab shape decorative pattern, rises
To skidproof effect.Protector can also be welded on cat ladder beam, it is to avoid touched during maintenance personal's climbing cat ladder outside engine
Surface.
Pedal 2 is installed on cat ladder 13, and above the engine of harvester, with engine exist certain safety away from
From.Particularly, the cat ladder also includes bracket 12, and bracket 12 is installed on the rear portion of grain box of harvester, cat ladder 13 and pedal 2
One end is overlapped on bracket 12, and is bolted to connection.Multiple long waist shaped holes, the week in long waist shaped hole are offered on pedal 2
Side has perpendicular folded plate, and perpendicular folded plate effectively strengthens the intensity of pedal.There is the breach of Wave crest and wave trough, multiple breach have on perpendicular folded plate
Add skidproof effect to effect.
Handrail is collapsibly installed on the side of pedal 2.Particularly, handrail includes pipe beam 5, lower pillar stand 4, upper handrail 1
With pin 6.Pipe beam 5 is fixed in the side of pedal 2, and lower pillar stand 4 is penetrated in pipe beam 5, and upper handrail 1 is hinged with lower pillar stand 4, and pin 6 runs through
The bottom of pipe beam 5, is passed with the bottom for limiting lower pillar stand 4 from pipe beam 5.The length of lower pillar stand 4 is less than the top of pipe beam 5 to pin 6
Distance.The external diameter of lower pillar stand 4 and upper handrail 1 is less than the internal diameter of pipe beam 5, can guarantee that lower pillar stand 4 and upper handrail 1 in pipe beam 5
There is less gap when inside is moved up and down and in the absence of interference.Further, handrail is symmetrical structure, and it has two
Individual pipe beam 5 and two lower pillar stands 4, upper handrail 1 are in inverted u-shaped.The bottom of upper handrail 1 opens up flat-ended protrusions, and high spot is provided with circle
Hole.The top of lower pillar stand 4 is provided with flat breach, and breach two end portions are provided with circular hole.The bottom circular hole of upper handrail 1 passes through rivet
Riveted with the top circular hole of lower pillar stand 4, handrail 1 is rotated around rivet relative to lower pillar stand 4.The cat ladder also includes deck
11, deck 11 is installed on the opposite side of pedal 2, and the handrail (i.e. upper handrail) after folding is connected in deck 11, plays locking effect
Really.Further, deck 11 can be made up of rubber, with certain elasticity.The top of deck 11 is provided with half round cut, and it half
The round heart is less than the upper end of deck 11.When upper handrail 1 falls into the breach on the top of deck 11, handrail 1 can be effectively blocked.
Fig. 1 shows structural representation when cat ladder proposed by the present invention is folded.Now, handrail is in folded state, above helps
Hand is fallen into deck, and the bottom for the lower pillar stand that its underpart is hinged is fallen into Guan Liang, and the axis of upper handrail and lower pillar stand is in 90 degree, from
And handrail is in restrained condition in left and right, upper-lower position.
Fig. 3 shows structural representation during cat ladder work proposed by the present invention.Now, handrail is in running order, above helps
Hand leaves deck, and upper handrail and lower pillar stand are coplanar, and the lower pillar stand that its underpart is hinged is fallen completely within Guan Liang, the bottom of upper handrail
Drop into Guan Liang, so that upper handrail is in restrained condition in right position.The bottom of lower pillar stand will be in contact in pin, and pin will
Lower pillar stand is supported, and prevents it from dropping.Now, cat ladder is climbed up in maintenance personal's climbing, when standing on pedal, can be helped and be gone up handrail,
Engine is crossed, tanker is arrived at, tanker inner part is overhauled.So as to avoid maintenance personal station from, without dependence, being deposited on cat ladder
The problem of personal safety is dangerous.
Harvester proposed by the present invention includes above-mentioned cat ladder structure.In harvester transport and transition operation, it will can climb
The handrail of ladder is folded, and upper handrail is connected in deck, locks it, so that the complete machine height of harvester has been effectively ensured, it is to avoid super
A series of parts damages problems that are high and bringing.
The above embodiments are merely illustrative of the technical solutions of the present invention, not for limit the present invention practical range.But
All equivalence changes done within the scope of the present invention and modification, have all been deemed to fall in protection scope of the present invention.
