Abstract

The utility model provides a hydraulic hammer structure of a drilling integrated machine, which comprises an upper hydraulic hammer body, a middle hydraulic hammer body arranged at the lower end of the upper hydraulic hammer body and a lower hammer body assembly arranged below the middle hydraulic hammer body.

Description

Hydraulic hammer structure of drilling all-in-one machine

Technical Field

The utility model relates to the field of engineering machinery, in particular to a hydraulic hammer structure of a drilling all-in-one machine.

Background

The hydraulic hammer belongs to an impact pile hammer and can be divided into a single-acting type and a double-acting type according to the structure and the working principle. The single-acting type means that the impact hammer core is lifted to a preset height through a hydraulic device and then is released quickly, and the impact hammer core strikes a pile body in a free-falling mode; the double-acting type means that after the impact hammer core is lifted to a preset height through a hydraulic device, acceleration energy is obtained from a hydraulic system to increase impact speed so as to strike a pile body. Two working states of drilling and piling need to be realized simultaneously in the drilling all-in-one machine, and the hydraulic hammer of ordinary structure can not adapt to the user demand.

SUMMERY OF THE UTILITY MODEL

In view of the above technical problems, the present invention provides a hydraulic hammer structure for a drilling integrated machine, including:

the hydraulic hammer upper part of the body, locate the hydraulic hammer middle part of the body lower extreme and locate the hammer lower part of the body subassembly of hydraulic hammer middle part of the body below, the hammer lower part of the body subassembly includes the hammer lower part of the body, locates the hammer piston of the hammer lower part of the body inner chamber, locate the hammer splint draw-in groove in the hammer lower part of the body outside, by hammer piston driven drill rod and be used for the installation the drill rod round pin of drill rod, be equipped with oil inlet and oil-out on the hydraulic hammer middle part of the body, be equipped with the inflation valve on the hydraulic hammer upper part of the body, the top of the hydraulic hammer upper part of the body is equipped with connecting bolt, be equipped with the bullet round pin on the hammer lower part of the body.

Has the advantages that:

1. the hydraulic hammer is combined with the drill rod, the operation requirement of the drilling all-in-one machine is met, the structural design of the hammer clamping plate clamping groove is adopted to realize reliable fixation, the stability is better in the drilling operation process, the hydraulic hammer is safer and more reliable, and the drilling angle is not prone to deviation.

Drawings

The utility model will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic overall structure diagram of an embodiment of the present invention;

FIG. 2 is a schematic view of the connection between the body of the hammer lower body and the drill rod according to the present invention.

The figures in the drawings represent:

1. the hydraulic hammer comprises a connecting bolt 2, an inflation valve 3, a hydraulic hammer upper body 4, a hydraulic hammer middle body 5, an oil inlet 6, an oil outlet 7, a hammer lower body 8, a hammer piston 9, a hammer clamp plate clamping groove 10, a drill rod pin 11, an elastic pin 12 and a drill rod.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "front", "rear", "left", "right", "upper", "lower", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, the hydraulic hammer comprises an upper hydraulic hammer body, a middle hydraulic hammer body arranged at the lower end of the upper hydraulic hammer body, and a lower hammer body assembly arranged below the middle hydraulic hammer body, wherein the lower hammer body assembly comprises a lower hammer body, a hammer piston arranged in the inner cavity of the lower hammer body, a hammer clamp plate clamping groove arranged on the outer side of the lower hammer body, a drill rod driven by the hammer piston, and a drill rod pin for mounting the drill rod, an oil inlet and an oil outlet are formed in the middle hydraulic hammer body, an inflation valve is arranged on the upper hydraulic hammer body, a connecting bolt is arranged at the top of the upper hydraulic hammer body, and an elastic pin is arranged on the lower hammer body.

The hydraulic hammer is combined with the drill rod, the operation requirements of the drilling all-in-one machine are met, reliable fixation is realized by adopting the structural design of the hammer clamping plate clamping groove, the stability is better in the drilling operation process, the hydraulic hammer is safer and more reliable, the drilling angle is not easy to deviate, and the hydraulic hammer is fixed on the drilling all-in-one machine through the connecting bolt during installation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
