Abstract
The utility model discloses an upper back type full-rotation rotary drilling rig. A drill rod upper back mechanism of the full-rotation rotary drilling rig comprises an excavator portion, a rotary excavation drill rod portion, a supporting arm, an oil cylinder and a support portion. A drill rod (1) of the rotary excavation drill rod portion is connected with the supporting arm (5) in hinged mode. The drill rod is further connected with a hydraulic oil cylinder enabling the drill rod to rotate vertically along the supporting arm, and the support portion for supporting the drill rod is arranged on a machine body on the rear portion of an excavator. The upper back type full-rotation rotary drilling rig has the advantages that 1 the problem that the gravity center is too close to the front is solved well, the transition is convenient, quick, safe and reliable, due to the fact that a whole movable arm of an original full-rotation excavator is abandoned and an upper back mechanism independently designed is adopted, the rotary excavation drill rod is in an upper back state when in transition, the transition can be performed very conveniently and quickly, and the hidden danger that an original structure can be turned over easily in running is thoroughly eliminated; and 2 the work hole forming is good in stability, when a hole is drilled, the distance between a chassis and a drill rod in working is shortened, and accordingly the working efficiency of the rotary drilling rig and stability of hole forming are improved.
Description
Technical field
The utility model belongs to full circle swinging rotary drilling rig technical field, and what relate generally to is to carry on the back mechanism on a kind of full circle swinging rotary drilling rig drilling rod.Adaptable across the installation of all full circle swinging rotary drilling rig drilling rods with fixing.
Background technology
At present, known all kinds of full circle swinging rotary drilling rigs all are on the architecture basics of existing excavator, remove and load onto rotary drill rod part back formation behind the original forearm of excavator and the bucket.As shown in Figure 1: rotary drill rod partly comprises drilling rod 1, hydraulic capstan 2, unit head 3 and drill bit 4, and it is installed in the connecting portion of original excavator forearm and big arm, and promptly drilling rod 1 and arm greatly 5 are fixedly connected through connector.Because receive the restriction of big arm lengths of excavator and height dimension, center of gravity is too forward, fuselage is unstable when causing boring, and the stake hole is crooked.In addition, owing to receive the structure and the stroke of big arm elevating ram and the restriction of installation site of the big arm of Spiral digging machine, in construction transition process, rotary drill rod partly is inclined (as shown in Figure 2) that is suspended from fore-body.Because body nodal point is too forward, not only walking is unstable, overturns easily, has very big potential safety hazard; And transition speed is slow, influences operating efficiency.
Summary of the invention
The purpose of the utility model produces thus, proposes a kind of back of the body formula full circle swinging rotary drilling rig of going up, and has realized carrying on the back on the rotary drilling rig purpose; Better solved the too forward problem of center of gravity; It is convenient and swift not only to cut to, and has improved the stability of rotary drilling rig operating efficiency and pore-forming, has stopped potential safety hazard.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of back of the body formula full circle swinging rotary drilling rig of going up comprises excavator part, rotary drill rod part, support arm and holder part; The drilling rod and the support arm of rotary drill rod part are articulated and connected; On drilling rod, also be connected with and make drilling rod along the hydraulic jack that support arm rotates up and down, the holder part that is used for supports drill rods is arranged on the fuselage at excavator rear portion.
The utility model reasonable in design compared with prior art, has the following advantages: 1) better solved the too forward problem of center of gravity, it is convenient and swift, safe and reliable to cut to.Because removed the upward back of the body mechanism that the whole swing arm of former full circle swinging digging machine has been used our independent design instead, like this, when transition, rotary drill rod is last back of the body state, can easily cut to quickly, has thoroughly solved the hidden danger of overturning easily when original structure is advanced; 2) work pore-forming good stability.When boring,, improved the stability of rotary drilling rig operating efficiency and pore-forming thus owing to shortened when drilling rod is worked and the distance between the chassis.
Description of drawings
The structural representation of Fig. 1 during for the boring of existing full circle swinging rotary drilling rig.
The structural representation of Fig. 2 during for the transition of existing full circle swinging rotary drilling rig.
Structural representation when Fig. 3 holes for the utility model.
Structural representation when Fig. 4 cuts to for the utility model.
Among the figure: 1, drilling rod, 2, hydraulic capstan, 3, unit head, 4, drill bit, 5, big arm (support arm), 6,
Support.
Concrete said mode
In conjunction with accompanying drawing, the embodiment that provides the utility model is following.
Combine shown in Figure 2 like Fig. 3: a kind of back of the body formula full circle swinging rotary drilling rig of going up comprises excavator part, rotary drill rod part and holder part.Excavator partly is on the architecture basics of existing excavator, removes the original whole swing arm of excavator, installed additional independent design support arm [Fig. 3 (5)].Rotary drill rod partly comprises drilling rod among Fig. 3 (1), hydraulic capstan (2), unit head (3) and drill bit (4); Drill bit (4) is fixedly connected on the lower end of drilling rod (1) through unit head (3); Hydraulic capstan (2) is fixedly connected on the drilling rod (1), is connected through fluid pressure line with unit head (3).Drilling rod among Fig. 3 (1) is articulated and connected through connector with the front end of support arm (5), between drilling rod (1) bottom and fuselage, also is connected with to make drilling rod rotate the hydraulic jack that moves up and down along support arm (5).This hydraulic jack is communicated with hydraulic system on the excavator through fluid pressure line.What be used for that the holder part of supports drill rods adopts is portal frame (6), is fixedly connected on the fuselage at excavator rear portion.
Claims (2)
1. go up back of the body formula full circle swinging rotary drilling rig for one kind; Comprise excavator part, rotary drill rod part, support arm, oil cylinder, holder part; The drilling rod (1) of said rotary drill rod part is articulated and connected with support arm (5); On drilling rod, also be connected with and make drilling rod along the hydraulic jack that support arm rotates up and down, the holder part (6) that is used for supports drill rods is arranged on the fuselage at excavator rear portion.
2. the back of the body formula full circle swinging rotary drilling rig of going up according to claim 1, it is characterized in that: what described holder part (6) adopted is portal frame.
