Summary of the invention
In order to overcome the difficulty of present high-altitude boring, the present invention---multi-functional stopping type high-altitude auger arises at the historic moment.The constructor only need stand on the ground, and the tumbler crank can easily be holed, and can drill through the hole of arbitrary height, and is time saving and energy saving, and boring accurately.
The technical scheme that the present invention deals with problems is: the top at heavy foot support (11) arranges a gear control (9), and the end that main elevating lever (7) has tooth tightly inserts in the gear control.Main elevating lever top connects the extension bar (4) of different length, and the extension bar upper end connects auger support (3).Stopping type depth controller (2) is located at the auger cantilever tip, is used for the keyhole degree of depth.Auger in the device (1), stopping type depth controller (2), multi-functional stopping type high-altitude auger switch (8) are connected in circuit.When " Z " of constructor's transmitting gear controller shape rocking bar (10), because the gearing of gear makes the lifting thereupon of main elevating lever.When boring reached the predefined degree of depth, stopping type depth controller top touched obstruction, the meeting automatic shutoff circuit, and auger quits work; When shifting out auger, dead circuit can be dynamically connected again certainly.
The principles of science of institute of the present invention foundation is:
1. heavy foot support (11) makes device more stable at vertical state in order to reduce the center of gravity of device.
2. during the traverse state, the constructor wants handle assembly and holds up, and must hold the middle part of device.According to lever principle, as if being fulcrum with the staff, then the suffered gravity of auger (1) is resistance.Do not weighing under the situation of foot support (11), staff must provide power to overcome resistance, relatively difficulty.And the heavy foot support suitable with the auger quality arranged, and then can replace the people that most of power is provided, easy when holding up like this.
3. in the gear control (9), only need a diameter 7cm, namely the gear of radius 3.5cm (20) gets final product.Its girth just has more than 20 centimetre.Because a circle is rotated in the gearing of gear, gear, main elevating lever (7) can rise or descend more than 20 centimetre;
4. gear control (9) is similar with connected mode and the chair lift of main elevating lever (7).Gear control inner surface and main elevating lever external surface are all smooth, add the effect of lubrication oil, make its two friction factor minimum.
5. gear axis (19) links to each other with " Z " shape rocking bar (10), still be lever principle this moment, only needing " Z " shape rocking bar length is more than four times of tooth radius (being that rocking bar length is about 15cm), and then the constructor only need apply fraction power, can realize the purpose of holing.
The invention has the beneficial effects as follows:
1. can drill through the vertical core of differing heights, because the effect of stopping type depth controller, drilling depth, position are accurate;
2. save and take terraced set in brickwork trouble, terrestrial operation, program is simple, and is time saving and energy saving, increases work efficiency, and removes the danger of high-altitude boring from, safe and reliable.
3. the constructor is avoided and a large amount of dust close contacts.
Whole device take up space little, conveniently moving;
5 devices can arbitrarily be dismantled, and assembling is simple, and is easy to carry.

The specific embodiment
In Fig. 1, design of the present invention, except heavy foot support (11), main elevating lever (7) and lifting screw (5) they are the heavier iron and steel of quality, remainder is the hard aluminium-alloy pipe of body lightweight.Highly being no more than 140cm (common laborer construct the most comfortable height) under the lifting screw its objective is and lower the center of gravity, and alleviate the weight of whole device, the constructor is more easy to operate.In the operating process, be down to main elevating lever (7) minimum earlier; The height that will hole of estimation is selected suitable connect extension bar (4) for use again, long down, shortly screw successively last, make when vertical, auger support (3) and target location are apart about 10cm.Can connect extension bar be provided with different length (1m, 0.5m, 0.2m) and several, just as platform scale, the thing in any scope is can weighing the same.Auger (1) is fixed on the auger support, fitting depth controller (2) notices how much shorter the depth controller top is than drill bit again, and namely how many predetermined depth is.Before upright, earlier auger (1) switch is in opening; After upright, hand is pressed switch (8), namely comes into effect drill tasks.When the degree of depth reached desired depth, stopping type depth controller (2) started, and circuit is disconnected.When shifting out auger, the interior circuit of stopping type depth controller (2) is connected automatically, and auger is started working again, the convenient taking-up.
Among Fig. 3, master link (7) has toothed portion tightly to cooperate with gear (21), and the relative motion part all has lubrication oil, and gear axis (19) two ends are connected with bearing, and bearing fixing is on heavy foot support (11).
Among Fig. 4, last copper sheet (14), following copper sheet (15) link to each other with insulating slab (18), and two leads link to each other with two copper sheets respectively.Spring (16) is placed on the spring shaft (17), and baffle plate is fixed, and like this, because the effect of spring makes down copper sheet be close to copper sheet, circuit is connected.Spring shaft is subjected to the extruding of obstruction and interior contracting finally makes down copper sheet separate with last copper sheet, and circuit disconnects.
Among Fig. 5, extension bar length difference in succession, but internal thread interface (21) can work in coordination with external screw thread interface (22), thus can connect as a whole.Length has 1m, 0.5m, 0.2m each several.
