Abstract

The utility model provides a technical scheme that is used for light-duty roofbolter of mine, traffic and building engineering. The said scheme features that the speed varying motor is used to drive the gear box to provide drilling power to the drill rod, the hydraulic system for the hydraulic oil cylinder to provide the drilling frame with lifting power, and the horizontal lifting unit of the drilling frame can regulate the drilling position conveniently.

Description

A kind of jumbolter

The utility model relates to the rig that mine, construction work are used, deep pit support retaining in particular for engineerings such as mine, traffic, civilian construction, on the ground, underground engineering support, edge improvement is waited on prevention landslide, and all kinds of engineering the drilling lightweight jumbolter of constructing.

At present, still do not have this type of light rig abroad, what its dynamical system of the jumbolter of domestic use adopted all is single machine driving or single hydraulic drive, so exist structure complicated, application life is short, inconvenient operation in construction, the big and low problem of efficient of labour intensity.

The purpose of this utility model provides a kind of simple in structure at the existing in prior technology problem exactly, at the scene the low technical scheme of being convenient to the jumbolter operated again of labour intensity in the construction.

This programme is realized by following technical measures.Jumbolter mainly be on the chassis, be equipped with control cabinet with creep into the adjusting support bar that frame is connected and regulate oil cylinder, motor is housed on the frame connects the drilling rod pass leading truck by gearbox creeping into, the characteristics of this programme are near leading truck one side a horizontal lifting gear to be housed also creeping between frame and the chassis; Described leading truck then be by with creep into guiding lower carriage that frame is connected and practice by strand and connect a guiding upper bracket, axis at least three rollers parallel with drill rod axis are housed on two stands.

In this programme, because the drilling system of drilling rod is the mechanical system that adopts motor, gearbox, and the lifting and the angle adjustment of creeping into frame are the hydraulic systems that adopts, and therefore, its junction structure is simple, uses reliable.In addition, increased the horizontal lifting gear that creeps into frame, made can adjust easily in construction and creep into the frame height, the variation that drill height adapts to the position, hole is adjusted thereby saved by manpower finishing place in the mating holes position exactly, has significantly reduced labour intensity.Also having leading truck is to be made of upper and lower two supports and roller, and this can promptly will change leading truck because of drill pipe diameter changes, and leading truck does not have serious wearing and tearing yet.This shows, the utility model compared with prior art, its effect is conspicuous.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the schematic top plan view of Fig. 1;

Fig. 3 is the structural representation of leading truck among the utility model embodiment;

Fig. 4 looks the part cross-sectional schematic for the left side of Fig. 3;

Fig. 5 is for creeping into the structural representation of the horizontal lifting gear of frame among the utility model embodiment.

Below by a specific embodiment and in conjunction with its accompanying drawing, this programme is described in further detail.Jumbolter mainly be on chassis 7, be equipped with control cabinet 10 with creep into the adjusting support bar 9 that frame 1 is connected and regulate oil cylinder 8, motor 2 is housed creeping on the frame 1, this motor 2 is the reducing motors that planet cycloid pinwheel deceleration device is housed, and is the XWD type speed reducer that adapts to generalization, the standardization needs adopt typing to produce.The shaft of this reducer connects gearbox 3, and gearbox 3 connects the drilling rod 5 that passes leading truck 4, transmits to drilling rod 5 and creeps into power.Described leading truck 4 then be by with creep into guiding lower carriage 13 that frame 1 is connected and practice by strand and connect a guiding upper bracket 11, it is parallel with drilling rod 5 axis that axis is housed on two stands, and along equally distributed four rollers, 12 formations of leading truck 4 endoporus circumference.In addition, a horizontal lifting gear 6 also is housed creeping between frame 1 and the chassis 7 near leading truck 4 one sides.This horizontal lifting gear 6 is that two guide pillars 14 that axis is parallel are installed on chassis 7, and there are a hoisting cross beam 15 and two guide pillars 14 to be slidingly connected 14 of two guide pillars, there is a hoist cylinder 16 middle part between two guide pillars 14, the bottom of hoist cylinder 16 is connected with chassis 7, the top is connected with hoisting cross beam 15, and hoisting cross beam 15 with creep into frame 1 and connect and compose described horizontal lifting gear 6.Hoist cylinder 16 in the horizontal lifting gear 6 and regulate oil cylinder 8 and cooperatively interact and just can adjust the angle of creeping into frame 1 bore angle can be changed between-10 to 90 degree can adapt to the needs that various angles are holed.
