Description
Technical Field
The utility model relates to an excavator quartering hammer technical field specifically indicates a cylinder body structure of excavator quartering hammer.
Background
The hydraulic breaking hammer used in the prior engineering has the defects of low efficiency, high noise and larger damage to the driving excavator due to the reaction of impact force. When the breaking hammer works, strong impact load is always applied, the impact load mainly acts on a drill rod of the breaking hammer, the force of the drill rod mainly acts on the friction between the internal structure of the breaking hammer and a piston, driving pressure oil enters the breaking hammer to strike the piston to push upwards, when the breaking hammer pushes a switching position of the piston, high-pressure hydraulic oil returns to a low-pressure cavity and does not drive the striking piston any more, the striking piston pushes out the piston at a downward flying speed through energy release of a nitrogen chamber at the instant of pressure oil pressure relief, the striking drill rod is struck, the internal cylinder body continuously rubs with the piston during working, and impact load is continuously generated on the inner wall, so that oil leakage or abrasion or damage can be easily generated on the inner wall, and the breaking hammer of the excavator needs to be replaced when reaching a certain service life after being used for a period of time. Currently, in the prior art, the breaking hammer is generally used for one to three years, and only a new breaking hammer can be purchased when the breaking hammer is replaced. Therefore, the cylinder body structure of the breaking hammer of the existing excavator is not ideal, and the requirement of long-time use cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model provides a use swift, and simple structure, preparation are easy, strengthened inside supporting force and tensile strength and abrasion resistance and the excavator quartering hammer's of extension quartering hammer live time cylinder body structure to overcome prior art's not enough.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an excavator quartering hammer's cylinder body structure, includes the cylinder body of excavator quartering hammer and sets up at the inside original main oil blanket slot of cylinder body, the cylinder body is inside to increase on the basis of original main oil blanket slot and is equipped with at least one main oil blanket slot, be equipped with logical oil structure in the cylinder body, it includes inlet port, oil outlet and sets up the oil groove of crossing in main oil blanket slot both sides to lead to oil structure.
As an improvement, the total number of the original main oil seal grooves and the main oil seal grooves is not more than three at most.
As an improvement, the groove surface of the joint of the main oil seal groove is a plane.
As the improvement, the number of inlet port and oil outlet is two and inlet port and oil outlet one-to-one intercommunication, the pipeline of inlet port and oil outlet intercommunication passes through the oil groove setting.
As an improvement, the diameter width of the main oil seal groove is consistent with that of the original main oil seal groove.
The utility model has the advantages that: the utility model discloses at reducible most frictional force of operation in-process and reinforcing tensile ability, the inside support of cylinder body has improvement by a wide margin, and hydraulic oil has the area of contact with inner structure to increase can effectually prevent the condition of oil leak, extravagant oil, and the whole life that can improve the quartering hammer part
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of a cylinder structure of a breaking hammer of an excavator of the present invention.
As shown in the figure: 1. the cylinder body 2, main oil seal slot, 3, inlet port, 4, oil outlet, 5, oil passing groove, 6, original main oil seal slot.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Combine figure 1, a cylinder body structure of excavator quartering hammer, including excavator quartering hammer's cylinder body 1 and the original main oil blanket slot 6 of setting in cylinder body 1 inside, 1 inside increase on the basis of original main oil blanket slot 6 of cylinder body is equipped with at least one main oil blanket slot 2, be equipped with logical oil structure in the cylinder body 1, logical oil structure includes inlet port 3, oil outlet 4 and sets up the oil groove 5 of crossing in main oil blanket slot 2 both sides.
The total number of the original main oil seal grooves 6 and the main oil seal grooves 2 is not more than three at most.
The groove surface of the joint of the main oil seal groove 2 is a plane.
The number of inlet port 3 and oil outlet 4 is two and inlet port 3 and the intercommunication of 4 one-to-ones in oil outlet, the pipeline of inlet port 3 and the intercommunication of oil outlet 4 passes through oil groove 5 and sets up.
The diameter width of the main oil seal groove 2 is consistent with that of the original main oil seal groove 6.
The method of the utility model is that at least one original main oil seal groove 6 is made on the front end part inside the cylinder body 1 of the breaking hammer of the existing excavator in advance, a main oil seal groove 2 with the same diameter and width is added on the cylinder body 1, and then an oil passing groove 5 is made at the position close to the main oil seal groove; therefore, the oil inlet hole and the oil outlet hole can pass through the oil passing groove without wasting oil, the interior of the cylinder body is more tensile and wear-resistant when the interior of the cylinder body and the piston are abraded, oil can not be discharged and leaked under the action of the oil inlet hole 3 and the oil outlet hole 4, and the supporting and contact area is enlarged.
