Description
Technical field
The utility model relates to excavation machinery field, in particular to a kind of shoveling backplate for wheel excavator joins
Dynamic device.
Background technique
The shoveling of excavator is played the role of excluding front obstacle, cleaning road or fixed main body under certain operating condition,
For example front obstacle can be cleared up during forward, and clear up road, additionally it is possible to material is pushed, convenient for loading, such as operation
When material excavate it is similar when, remaining material is difficult to dig into bucket, at this moment cooperate shoveling operation, scraper bowl is in preceding, shoveling
Rear, work in coordination, material can dig into scraper bowl；In digging operation, equally dozer flexibly can be used,
For the stable fuselage that prevents from caving in, it is bulldozed work surface and backfills etc.；In lifting operation, it is sometimes desirable to lift blender, water
Mud pipe etc., stable fuselage can be played the role of by this moment putting down shoveling.Shoveling is relatively simple for structure, but needs oil cylinder as power source
Control is risen and fallen, in current shoveling, oil cylinder be all it is exposed outside, in operation process be easy oil cylinder is caused to damage, reduce oil cylinder
Service life.
Summary of the invention
In order to make up for the defects of the prior art, the utility model provides a kind of protection oil cylinders for wheel excavator
Shoveling backplate linkage.
The utility model is achieved by the following technical solution:
A kind of shoveling backplate linkage for wheel excavator, it is characterized in that: including being welded on excavator main car frame
On one group of upper pin plate and two groups of lower bearing pin plates, by upper pin hinged oil cylinder on the upper pin plate, the oil cylinder it is defeated
Outlet is hinged on the back side of shoveling plate, and the back side of the shoveling plate is fixedly connected with two connecting rods, and two connecting rods are respectively in oil
The two sides of cylinder, the other end of each connecting rod are hinged on one group of lower bearing pin plate with its same side；In the upper end of shoveling plate
The free end of hinged oil cylinder backplate, the oil cylinder backplate rides on oil cylinder.
The back side of the oil cylinder backplate is equipped with idler wheel.
Limit plate is equipped with by torsionspring on main car frame, the limit plate is the V-type stood upside down from the side；In main vehicle
The block of one piece of the welding machine gradient for limiting limit plate on frame.
The beneficial effects of the utility model are:
The utility model is provided with the oil cylinder backplate being hinged on shoveling plate, and oil cylinder backplate leans against always oil by own wt
On cylinder, as oil cylinder rises and falls, protective effect played to oil cylinder, and the idler wheel of oil cylinder backplate setting, so that oil cylinder backplate is in oil
Movement on cylinder is more smooth, is more convenient.Limit plate on main car frame plays position-limiting action to oil cylinder backplate, can prevent oil cylinder
Backplate is overturn in some special circumstances, loses protective effect.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the left view structural representation of the utility model；
Fig. 2 is the schematic perspective view of the utility model；
Fig. 3 is the schematic perspective view that the utility model removes limit plate；
Fig. 4 is the separate structure schematic diagram of Fig. 3.
In figure, 1 main car frame, 2 upper pin plates, 3 lower bearing pin plates, 4 vertical plates, 5 upper pins, 6 oil cylinders, ear pin on 7,8 zinc-plated spiral shells
Silk, 9 zinc-plated high pressure spring washers, 10 plain cushions, 11 high pressure nuts, 12 shoveling plates, 13 connecting rods, 14 oil cylinder backplates, 15 mounting plates, 16 pins
Axis, 17 split pins, 18 idler wheels, 19 torsionsprings, 20 limit plates, 21 blocks.
Specific embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figures 1 to 4, this kind is protected for the shoveling of wheel excavator
Plate linkage, welds one group of upper pin plate 2 and two groups of lower bearing pin plates 3 on excavator main car frame 1, upper pin plate 2 upper, under
Under, upper pin plate 2 and lower bearing pin plate 3 are distributed pin shaft plate 3 according to isosceles triangle, and upper pin plate 2 and lower bearing pin plate 3 are referred to as pin
Axillare, every group of pin shaft plate are made of two pieces of parallel vertical plates 4, pass through 5 hinged oil cylinders 6 of upper pin, oil cylinder on upper pin plate 2
Obliquely, this upper pin 5 includes a upper ear pin 7 to 6 output end, after upper ear pin 7 passes through the hole of upper pin plate 2 and oil cylinder 6,
The hole on upper ear pin 7 is passed through with a galvanized screw 8 again, upper zinc-plated high pressure spring washer 9 and plain cushion are then covered on galvanized screw 8
10, then tightened with high pressure nut 11；The output end of oil cylinder 6 is hinged on the back side of shoveling plate 12, is carried on the back in oil cylinder 6 and shoveling plate 12
The two sides of the hinge joint in face are each to fix a connecting rod 13, certainly hinged good, and the other end of connecting rod 13 is then hinged on and connects
Extension bar 13 is located on the lower bearing pin plate 3 of the same side, the articulated manner of connecting rod 13 and lower bearing pin plate 3, oil cylinder 6 and shoveling plate 12 with
Oil cylinder 6 is identical as the articulated manner of upper pin plate 2, repeats no more；
In the hinged one piece of oil cylinder backplate 14 in 12 upper end of shoveling plate, articulated manner are as follows: the both ends of oil cylinder backplate 14 are bent backwards,
Then it drills in dogleg section lower end, welds mounting plate 15 in 12 upper end of shoveling plate, also drill on mounting plate 15, thus there is two
Group hole, every group of hole are passed through with a pin shaft 16, then put on a plain cushion, then the insertion opening pin 17 in the hole of pin shaft 16, then
The tail portion of split pin 17 is broken curved；
Equally pass through pin shaft, plain cushion and split pin at the back side of oil cylinder backplate 14 and one idler wheel 18, idler wheel 18 and oil are installed
Cylinder backplate 14 rides on oil cylinder 6 by self gravity, and during oil cylinder 6 drives shoveling plate 12 to rise and fall, idler wheel 18 is just on oil cylinder 6
It rolls.
In order to prevent when bringing to a halt, oil cylinder backplate 14 is overturn, and can also pass through torsionspring on main car frame 1
19 one piece of limit plate 20 of installation, weld one piece of block 21 again on main car frame 1, limit the gradient of limit plate 20, and block can be with
There are two pieces, is respectively in the two sides of upper pin plate；Limit plate 20 is located at the top of oil cylinder backplate 14, and limit plate 20 from the side, is
The V-type of handstand.A gap is opened among the side close to torsionspring, upper pin plate 2 is located in this gap.Limit plate and
Just as an agrafe, limit plate can be rotated for the combination of torsionspring.Limit plate can be hinged on main car frame.It can also
To be only fixed on torsionspring, and it is not connect with main car frame.Limit plate may exit off oil cylinder to after main car frame partial turn
The top of backplate enables oil cylinder backplate to overturn, in order to dismantle, maintenance.
In addition to the technical characteristic described in the specification, remaining technical characteristic is technology known to those skilled in the art.
