Abstract

The utility model belongs to drilling machine machinery, specially adapted building trade is beaten post stake hole and is used. A winch is used for directly hanging a drill body with a plurality of drill bits to lift through a steel wire rope and a middle pulley, and the drill body consists of a motor, a speed reducer, a coupler, a middle gear shaft, a middle drill bit, an inert gear, a side drill bit and a bearing. The front end of the drill bit is made into a small spiral for guiding, and the middle part of the drill bit is made into a large spiral chip groove for removing chips. The drilling machine is used by a user and is popular with the user.

Description

The Ni Zhifu drill churn

The utility model belongs to the rig mechanical field, is specially adapted to building trade and plays the use of stanchion hole.

The rig kind of usefulness is more at present, and form is different, and the place that is suitable for is also variant.For example: just have gear wheel to bore in the prospecting mineral resources, the brill of general drill bit, hidden hole drilling etc.These rigs all are to bore to the degree of depth with the way of spreading drilling rod, and drill bit can not elevate generally speaking, only just drill bit are gone up under the situation of bit change more.The way that goes out bits is to adopt the recoil ability of swimming that drilling cuttings is become mud to go out.It generally also is that the way of the spreading drilling rod of usefulness is bored to the degree of depth that building trade is made rig that stanchion uses, but the mode that goes out bits is just just different with the rig of prospecting mineral resources, making rig that stanchion uses, to go out bits be to adopt the way that promotes drill bit, drilling cuttings is taken out of, just utilized the slot part on the drill bit that drilling cuttings is taken out of.This form that drill bit just has been described is different, and explanation is beaten stanchion and promoted drill bit continually with rig in addition.That adopts at present makes the stanchion rig, resembles Zhengzhou Prospecting Machinery Plant introduction Britain BSP company technology, and the TCA75 rig of production is exactly a kind of of dozen stanchion rig.Rig like this all is to have only a drill bit, and with drill bit drive part, drilling rod, drilling rod elevating mechanism, platform and mast are formed.Because it has only a drill bit, the hole of common buildings stanchion, diameter is bigger, and requires once to be drilled to, so the diameter of drill bit will do greatlyyer, and bit diameter main point demanded driving force is just big; Rig like this in addition all is the way that adopts the spreading drilling rod toward degree of depth brill, and is both time-consuming, increases the cost of rig again; Owing to will change drilling rod, just need a high mast, for promoting drilling rod usefulness, also increased the cost of rig, the more important thing is the volume that has increased rig, because volume has greatly also increased the difficulty of carrying.In order to reduce rig cost, improve rig efficient, reduce difficult, it is low to redesign a kind of cost, efficient height, the rig of convenient in carrying.

The purpose of this utility model, it is little to design a kind of volume exactly, and cost is low, efficient height, the rig of convenient in carrying.

Designer of the present utility model has designed a kind of Ni Zhifu drill churn.With the hoist engine that is fixed on the platform, directly hang a drill body lifting exactly, carry out drilling well work with a plurality of drill bits by wire rope, intermediate pulley.Drill body is made up of motor, reductor, shaft coupling, middle gear axle, middle drill bit, sloth wheel gear, side gear, limit drill bit and bearing.The front end of drill bit is made minor spiral, and as guiding usefulness, king bolt is made in the centre, uses as taking drilling cuttings out of.

The utility model is compared with other rig of building foundation, because it has adopted wire rope directly to hang drill body and has just omitted drilling rod, high mast or high tower have also just been omitted after omitting drilling rod, this has just saved and has changed the drilling rod space, also joint changes the drilling rod space simultaneously, just reduce whole rig volume, also just reduced cost.Because drill body is made up of a plurality of drill bits, drill bit is also big with regard to neither one bit drills machine drill head, and it is also just more convenient to make drill bit, especially to big stanchion hole drill bit.So it is little that this rig has a volume, cost is low, efficient is high, the advantage of convenient in carrying.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the utility model structural representation.

Fig. 2 is the sectional view of the drill body (2) of Fig. 1.

Describe the utility model details and working condition in detail below in conjunction with Fig. 1, Fig. 2.

Hoist engine (1) is housed having on the platform of wheel, open the shelves that hoist engine descends drill body (2), when drill body drops to drill bit (9) kiss the earth, close hoist engine, adjust brake gear, make wire rope (3) keep tensioning state, and can descend with drill bit, this decline is the gravity that relies on drill body (2).At this moment start drill body motor (4), drill body is started working, after drill bit middle part king bolt slot part is full of by drilling cuttings, close the drill body power supply, open hoist engine then drill body is mentioned, behind the whole built on stilts of drill body, start the drill body motor, rotary drill bit gets rid of drilling cuttings in the helical flue of drill.Here it is a drilling period, repetition successively.When drill body (2), motor (4) start, reductor (6) is started working, drive middle gear axle (7) and middle drill bit (9) rotation by shaft coupling (6), the middle gear axle rotates by four sloth wheel gears of middle gear band (8), sloth wheel gear drives eight side gears (11) again and rotates, and has also just driven eight limit drill bits (10) and has rotated.These gear shafts all have bearing (12) to locate.Can change different drill bits and carry out work according to the soil layer situation is different, also can be made into slip casting method simultaneously and carry out work.The position of having arranged nine brills in the current gear-box, also can by the variation of transmission arrange drill bit how much.This rig effect after trying out is fine, is subjected to very much the welcome of building trade.

Claims

1, a kind of platform by the band wheel, the Ni Zhifu drill churn that vertical rod, pulley etc. are formed, it is characterized in that: drill body (2) is by motor (4), reductor (5), connect with intermediate gear shaft and center tooth connection (7) by shaft coupling (6), middle drill bit (9) is contained on the intermediate gear shaft, idler gear connects with sloth wheel gear and sloth wheel gear axle (8), sloth wheel gear connects with side gear and heel teeth wheel shaft (11) again, limit drill bit (10) is housed on the heel teeth wheel shaft, and intermediate gear shaft, sloth wheel gear axle, heel teeth wheel shaft have bearing (12) to locate.

2, Ni Zhifu drill churn according to claim 1 is characterized in that: the front end of drill bit (9), (10) is made minor spiral, and the king bolt chip pocket is made at the middle part.
