Abstract

The utility model relates to a fully hydraulic drill used for the civil construction and preserves the most mechanism and system of an excavator except a low arm mechanism and a bucket mechanism. The fully hydraulic drill also includes a mast(10), a power head(14) inserted in the mast(10) which provides a hydraulic motor(13) and a boring mechanism; a guide wheel(12) is fixed on the coping of the mast(10), a clamping cylinder(15) and a fixed pulley are fixed on the lower end of the mast(10), a lifting cylinder(11) and two mobile wheels in upper and lower parts are fixed in the internal mast(10); the two mobile wheels wholly connect with the lower end of the lifting cylinder(11), the wheel ropes of the two mobile wheels both have one side fixed on the upper or the lower end of the internal mast(10) shell, another sides thereof separately bypass the guide wheel(12) and the fixed pulley and fix on the power head(14). The utility model is improved basing on the excavator and has advantages of high reliability, simple and convenient operation, low cost fabrication, convenient maintenance, fewer faults and more functions and so on.

Description

All-hydraulic drill

Technical field

The utility model relates to a kind of rig, and more particularly, the utility model relates to a kind of all-hydraulic drill.

Background technology

At present, the all-hydraulic drill that in engineering construction, uses, be that the hydraulic power unit produced by specialized factory is to unit head motor, walking mechanism and lift cylinder fuel feeding, finish the moving up and down of walking, unit head of rotation, the all-hydraulic drill of unit head motor, operating system is made up of electrical system and hydraulic operating system, this kind hydraulic drill rig cost height, complicated operation, the fault rate height, maintenance difficult, function singleness.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cost low, easy and simple to handle, makes simply multifunctional all-hydraulic rig for ease of maintenaince.

The purpose of this utility model realizes by following proposal.

A kind of all-hydraulic drill, the big arm oil cylinder that comprises the all-hydraulic drill main frame, is connected big arm on the all-hydraulic drill main frame, is connected with big arm on the all-hydraulic drill main frame, the mast angle adjustment oil cylinder that is connected with mast on the arm greatly are equipped with power source, walking mechanism, console switch and oil pump on the described all-hydraulic drill main frame; Described all-hydraulic drill also comprises the mast that is connected on the big arm, be inlaid in unit head on mast gathering sill or the guide rail, be installed in hydraulic motor and probing mechanism on the unit head; Described mast top is equipped with directive wheel, mast housing lower end and lower end in clamping oil cylinder, mast gathering sill or the guide rail is housed fixed pulley, mast inside is housed lift cylinder and two movable pulley one on the other are housed; Described two movable pulley integral body one on the other are connected the lift cylinder lower end, one end of last movable pulley wheel rope is fixed in the mast housing upper wall, the other end and walks around directive wheel and be fixed on the unit head, and an end of following movable pulley wheel rope is fixed on the fixed pulley that lower end, the other end in the mast housing walk around in mast gathering sill or the guide rail and is fixed on the unit head.

Advantage of the present utility model: (1) reliability height, few maintenance; (2) simple in structure, be easy to make, on hydraulic crawler excavator, changed, just can finish; (3) all-hydraulic control, behaviour does easy; (4) low cost of manufacture, easy to maintenance; (5) circuit breaks down does not influence this all-hydraulic drill work; (6) multifunctionality.

Description of drawings

Fig. 1 is the hydraulic crawler excavator right flank schematic diagram of the utility model background technology;

Fig. 2 is the utility model right flank cross-sectional schematic.

Identify among the figure: 1-hydraulic excavating machine host, the big arm of 2-, 3-forearm oil cylinder, the 4-forearm, 5-bucket cylinder, 6-bucket, 7-ejector dozer oil cylinder, the big arm oil cylinder of 8-, 9-mast angle adjustment oil cylinder, the 10-mast, 11-lift cylinder, 12-directive wheel, the 13-hydraulic motor, 14-unit head, 15-clamping oil cylinder, the big arm of 16-, 17-all-hydraulic drill main frame, the big arm oil cylinder of 18-.

Specific embodiment

Below in conjunction with Fig. 1, Fig. 2 the utility model is described in detail:

In the utility model; Keep; Utilized except oil cylinder of small arm 3; Forearm 4; Mechanism and the system of the most excavators beyond the associated mechanisms such as bucket cylinder 5 and bucket 6; Adopt hydraulic excavating machine host 1 as full-hydraulic drill machine host 17; Adopt hydraulic excavating machine host 1 as power source and the crawler type walking mechanism of hydraulic drill rig; Adopt the big arm 2 of hydraulic crawler excavator as the big arm 16 of all-hydraulic drill; The oil circuit of hydraulic crawler excavator big arm cylinder 8 is as the oil circuit of hydraulic drill rig big arm cylinder 18; The flexible height that can improve and reduce mast 10 of big arm cylinder 18; The oil circuit of hydraulic crawler excavator oil cylinder of small arm 3 is as the oil circuit of hydraulic drill rig mast angle adjustment oil cylinder 9; Stretching of it; Can adjust the front and rear angles of mast 10; The oil circuit of bucket cylinder 5 is as the oil circuit of hydraulic drill rig hydraulic motor 13; The flexible operation of bucket cylinder 5 can be finished the forward or reverse of hydraulic drill rig hydraulic motor 13; The oil circuit of hydraulic crawler excavator ejector dozer oil cylinder 7 is as the oil circuit of lift cylinder 11; The flexible operation of hydraulic crawler excavator ejector dozer oil cylinder 7 can be finished raising and the reduction of unit head 14, and crushing head uses oil circuit as the oil circuit of clamper oil cylinder 15. Big arm oil cylinder 8 on the direct control excavator, forearm oil cylinder 3, bucket cylinder 5, ejector dozer oil cylinder 7, crushing head just can be realized the raising and the reduction of hydraulic drill rig mast 10 with the console switch of oil circuit, adjust before and after the angle of mast 10, hydraulic motor 13 rotates, moving up and down of unit head 14, the clamping of clamping oil cylinder 15 and loosening; Can exchange between each oil circuit; Connect by big arm 16 between all-hydraulic drill main frame 17 and the mast 10, directly utilize each console switch of hydraulic crawler excavator just can operate all-hydraulic drill; All-hydraulic drills became hydraulic crawler excavator again after all-hydraulic drill was changed forearm oil cylinder 3, forearm 4, bucket cylinder 5, bucket 6, realized multi-functional.
