Description
Technical Field
The invention relates to the technical field of excavators, in particular to an anti-sinking device for soft ground of an excavator.
Background
The crawler excavator can be applied to various working conditions such as earthwork, mines, wetlands with certain hardness and the like due to the use of the crawler, but cannot be used under the working conditions of relatively soft (such as mud lands, marshlands and the like), because the crawler can be sunk too deeply after the machine enters the working conditions, and the situation that the crawler cannot normally walk due to skidding can occur after the crawler runs.
In many current applications, for the working condition that the ground is relatively soft (such as mud, marsh), a method of widening the track shoe is generally adopted, so that the contact area between the machine and the ground is increased, and the contact pressure between the machine and the ground is reduced.
In the prior art, a method for increasing the ground contact area by increasing the width of the track shoe has a certain limitation, and the method can only be increased in a small range, if too much increase occurs, on one hand, the situation that the excavator cannot turn due to too large resistance when turning occurs. On the other hand, since the height of the middle part of the frame is generally higher than the upper surface of the crawler belt, if the width of the crawler belt plate is excessively increased, interference with the frame may occur.
Disclosure of Invention
Aiming at the problems, the invention provides the soft ground sinking preventing device for the excavator, which greatly increases the contact area between the excavator and the ground compared with the traditional method and can effectively prevent the excavator from sinking into the soft ground in the working process.
The technical scheme provided by the invention is as follows:
an anti-sinking device for soft ground of an excavator comprises a supporting plate, an oil cylinder, an upper lug plate, a pin shaft and a frame; the upper surface of the supporting plate is provided with a plurality of upper ear plates, and holes are formed in the upper ear plates; the oil cylinder is connected in the hole of the upper lug plate through a pin shaft; the oil cylinder is connected to the frame through bolts; the two ends of the supporting plate are provided with bulges, and the lower surface of the supporting plate is provided with a plurality of grooves.
Further, the soft ground anti-sinking device of the excavator is arranged between the tracks on two sides.
Further, the width of the support plate is smaller than the distance between the two side tracks.
Further, the length of the support plate is less than the track length.
Further, the protrusions are arc-shaped.
Further, the number of the grooves is 5-10.
Further, the oil cylinder is provided with two groups, which are respectively arranged in front of and behind the machine.
The invention also provides a use method of the soft ground anti-sinking device of the excavator, when the excavator works under the common ground working condition, the supporting plate is lifted up through the oil cylinder, and when the ground is softer, the supporting plate is lowered, the grounding area is increased, and the machine is prevented from sinking.
Further, the bolt holes on the oil cylinder correspond to the mounting holes of the frame, and then the bolts are screwed in, so that the oil cylinder is fixed on the frame; and (3) corresponding the holes of the upper lug plate arranged on the supporting plate with the holes on the oil cylinder, and then pressing the pin shaft.
The invention also provides an excavator, which is provided with the soft ground sinking preventing device of the excavator.
Advantageous effects
When the machine works under the working conditions of wetlands such as mud lands and marshlands, the piston rod of the oil cylinder descends to support the supporting plate on the ground, and compared with the traditional method, the contact area between the machine and the ground is greatly increased, and the machine can be effectively prevented from sinking into soft ground in the working process. When the machine needs to walk, the supporting plate is properly lifted according to the condition of loose ground, but the supporting plate is not separated from the ground, so that the friction assistance of the supporting plate and the ground can be reduced, meanwhile, the contact stress of the two tracks and the ground is increased, the machine is ensured to still walk normally under the working condition of the loose wetland with the supporting plate, and the problems of limited increase of the grounding area and large walking resistance in the traditional method are solved.
In the technical scheme of the invention, the supporting plate has a lifting function, can be supported on the ground when required, increases the contact area of the machine and prevents the machine from sinking. Meanwhile, due to the fact that the protrusions at the two ends of the supporting plate are used, running resistance of the machine can be reduced, the rigidity of the supporting plate is increased due to the fact that grooves of the supporting plate are used, weight of the supporting plate can be effectively reduced, and the weight of the machine is prevented from being increased due to the fact that the weight of the supporting plate is increased too much.

Detailed Description
Example 1
The soft ground anti-sinking device of the excavator is arranged between the tracks on two sides; the hydraulic support comprises a support plate 1, an oil cylinder 2, bolts 3, an upper lug plate 4, a pin shaft 5 and a frame 6. The upper surface of the supporting plate 1 is provided with a plurality of upper ear plates 4, and round holes are formed in the upper ear plates 4. The two ends of the supporting plate 1 are provided with bulges 7, the bulges 7 are arc-shaped, and the lower surface of the supporting plate 1 is provided with a plurality of grooves 8. The number of the grooves is 5-10; the arrangement of the grooves can increase the rigidity of the supporting plate, and destroy the surface tension of water in the wet ground, so that the lifting resistance of the supporting plate is smaller, and the supporting plate has better supporting effect; the oil cylinder 2 is connected into a round hole of the upper lug plate 4 through a pin shaft 5; the oil cylinder 2 is connected to a frame 6 through bolts 3. When working on the common ground, the supporting plate can be lifted up through the oil cylinder, and when the ground is softer, the supporting plate is lowered, the grounding area is increased, and the machine is prevented from sinking. The lifting height range of the supporting plate can be set to be 0-600 mm; the width of the supporting plate is smaller than the distance between the two side tracks.
When the hydraulic cylinder is installed, the bolt holes on the hydraulic cylinder 2 are corresponding to the installation holes of the frame 6, and then the bolts 3 are screwed in, so that the hydraulic cylinder 2 is fixed on the frame 6. The holes of the upper lug plate 4 arranged on the supporting plate 1 correspond to the holes on the oil cylinder 2, and then the pin shaft 5 is pressed in.
In another embodiment, two sets of lift cylinders are provided, one in front of and one behind the machine. When the machine works on soft ground working conditions such as mud lands, marshes and the like, the machine can be prevented from sinking, and normal walking is guaranteed.
The invention also provides an excavator, which is provided with the soft ground sinking preventing device of the excavator.
