Abstract
The utility model relates to an axially water inlet engineering driller, which comprises a body, a gear case, a head, an output shaft, and a water pipe. The output shaft is disposed on the head through a bearing. The water pipe is disposed on the center of the output shaft by a miniature bearing through the center of the output shaft. Cooling water enters from an inlet provided on the gear case to an outlet through the water pipe and then to be enclosed. The utility model has advantages of a novel structure, favorable sealing performance, small volume, non-leakage, and long service life, pertaining to a new axially water inlet engineering driller integrating economy and practicability.
Description
Axial water inlet engineering driller described in the utility model is a kind of in wall boring or a kind of engineering machinery of using at hard geological sampling.
Along with improving constantly of living standards of the people, the house finishing is also more and more.Wall boring was by rig or electric hammer punching in the past in the decorating house process, and warp-wise water inlet engineering driller had been arranged afterwards, and the cooling water of this rig is from the water inlet of rig head, enters output shaft by warp-wise, entered a center from output water and flow to drill bit and cool off.The subject matter of this rig is output axial length, has influenced the running accuracy of rig.Be exactly after cooling water enters the rig head in addition, can only rely on seal washer sealing, grown service time output shaft is got rusty, make the seal washer ageing failure, water is flowed out from the rig head, influence cooling effect.Even more serious is that cooling water also may enter gear-box, and bearing and gear are damaged.It is useless to cause rig to be thrown.At existing problem in the prior art, a kind of novel axial water inlet engineering driller of research and design, existing problem is very necessary in the prior art thereby overcome.
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel structure of research and design, good seal performance, nothing leakage, volume is little, precision is high, the axial water inlet engineering driller of life-span length.The utility model adopts cooling water pipe directly to be entered by the rear end of output shaft, passes from the output shaft center, to output shaft front end delivery port, cooling water and output shaft is kept apart, and cooling water is closed.
The rig life-span is prolonged, shortened the rig head dimensions, improved precision, use, so the utility model is a kind of economical and practical novel axial water inlet engineering driller applicable to various different places and working environment.
Axial water inlet engineering driller described in the utility model; So its structure is being made up of body, gear-box, head, output shaft, water pipe; Output shaft is contained in head by bearing.Water pipe is entered by the water inlet of gear-box, passes through to delivery port at the output shaft center, and is contained in output shaft by miniature bearing.Main shaft rotates by the gear driven output shaft.At output shaft and delivery port place seal washer is housed.Output shaft described in the utility model is a hollow, and water pipe passes from the centre.
The utility model provides a kind of novel axial water inlet engineering driller, thereby the cooling water water intake mode of existing engineering driller is improved.Released a kind of novel axial water inlet engineering driller to market.The utlity model has novel structure, advantages such as volume is little, precision is high, good sealing effect, long service life.It is put on market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
The utility model has two accompanying drawings, wherein
Accompanying drawing 1: the engineering driller external form of axially intaking schematic diagram
Accompanying drawing 2: the journey of axially intaking is bored the chain-drive section generalized section
Among the figure: 1, body 2, water inlet 3 gear-boxes 4, head 5, output shaft 6, delivery port 7, gear 8, bearing 9, miniature bearing 10, water pipe 11, seal washer 12, main shaft
Specific embodiment of the utility model as shown in drawings, its structure is at the rear portion of body motor to be housed, the driven by motor main axis rotation drives the output shaft rotation work by gear graduation.Output shaft is contained in the head of body by bearing.Cooling water pipe passes at the center of output shaft.Cooling water enters from the water inlet on the sidewall of gear-box, by the water pipe arrival delivery port at output shaft center.Owing to add sealing filler ring at delivery port and output shaft place, make cooling water can not turn back to the output shaft centre bore.Because cooling water arrives delivery port from water inlet through water pipe and all seals, so can not leak into gear-box and head.Make rig be difficult for burn into and prolonged service life, make volume-diminished simultaneously.
