Description

Pipeline bores

The utility model belongs to the drilling tool that use is punched on in-service pipeline, particularly a kind of pipeline bores.

Present existing similar brill, as Fig. 1, drill body is a shelf 1, the bottom be pipe thread joint 2 be installed in can the gate of standard-sized sheet on 3, gate is connected on the special clamp 4, and is fixed on the pipeline that needs the grafting pipe 5.Drilling rod 6 drill bits 7 act directly on the pipeline by the gate of standard-sized sheet.Spanner 8 is moved drilling rod is rotated.Push rod 9 is given drilling rod jacking pressure.After the boring of pipeline is got through, drilling rod, drill bit can be fallen back in the pipe thread joint.Closed shutter, unload drill body, later on the skill pipeline is connected just with gate and can puts into operation, long-pending, the operation effort, time-consuming big of this drill body with weight.

The purpose of this utility model provides a kind of pipeline and bores, and adopts sleeve, guide block, has substituted shelf and push rod, has added bearing etc., has overcome above original drilling tool deficiency and shortcoming.

The purpose of this utility model is achieved in that

A kind of pipeline bores, and it is characterized in that: be made up of pipe thread joint, sleeve, guide block, drilling rod, drill bit, spanner; Pipe thread joint top branch sleeve, sleeve upper interior center edge is joined guide block, between the guide block sleeve bearing is arranged, and bearing outside cooperates with sleeve lining, drilling rod, pipe thread nipple tip drilling rod are passed by having located packing seal in pipe thread joint and sleeve guide block center, the drilling rod bottom drill bit that is threaded; The drilling rod external diameter has acme thread to match with the acme thread of guide block inwall, and sleeve is outer very heavy by what be made up of handle, ratchet, spring, on the guide block outer wall breaker slot is arranged, and very heavy ratchet cooperates with breaker slot on the guide block outer wall; Spanner is the spring spanner, has had clamp dog on the spanner, plays taking off on the outer very heavy handle of clamp dog and sleeve and makes cooperating, and makes outer very heavy the moving up and down of sleeve.

Spanner is outer very heavy by what be made up of handle, ratchet spring, and the cylindrical of spanner inner core is a ratchet.It is very heavy to cooperate with ratchet.

The pipe thread joint top sleeve that is threaded, there is external screw thread pipe thread joint below, can be connected with the internal thread on the pipe closer door.

The sleeve of pipe thread joint and top can be the type of attachment of flange.

Drill bit is the drill bit of cast also.

The utility model has the advantages that: volume is little, and is in light weight, saves material, and autofeed processing is easy, easy and simple to handle, time saving and energy saving, installs rapidly, and applicable situation is extensive.

Below in conjunction with description of drawings implementing process example:

A kind of pipeline bores, and is made up of pipe thread joint 10, sleeve 11, guide block 12, drilling rod 13, drill bit 14, spanner 15; Pipe thread joint top branch sleeve, sleeve upper interior center edge is joined guide block, and guide block is with axle outward, and bearing outside cooperates with sleeve lining, drilling rod, pipe thread nipple tip drilling rod are passed by having located filler 16 sealings in pipe thread joint and sleeve guide block center, and drilling rod bottom screw thread 17 connects drill bit; The drilling rod external diameter has acme thread 18 to match with the acme thread 19 of guide block inwall, and sleeve is outer very heavy by what be made up of handle 20, ratchet 21 springs 22, and breaker slot 23 is arranged on the guide block outer wall, and very heavy ratchet cooperates with breaker slot on the guide block outer wall; Spanner is the spring spanner, has had clamp dog 24 on the spanner, and the system of taking off that rises on the outer very heavy handle of clamp dog and sleeve cooperates 25, makes outer very heavy the moving up and down of sleeve.

Spanner is outer very heavy by what be made up of handle 26, ratchet 27, spring 28, and the cylindrical of spanner inner core is a ratchet 29.It is very heavy to cooperate with ratchet.

Square thread 30 branch sleeves on the pipe thread joint, there is external screw thread 31 pipe thread joint below, can be connected with the internal thread on the pipe closer door.

Adopt sleeve, guide block, bearing to substitute original shelf and push rod.

Drill bit is the drill bit 32 of cast also.

Main accessory; Pipe thread joint (Fig. 2), sleeve (Fig. 3), spanner (Fig. 6) drilling rod (Fig. 8), drill bit, guide block (Fig. 9), bearing, very heavy (Figure 10), filler are formed.

(1) pipe thread joint: see that Fig. 2 two ends connect gate, last termination sleeve for the gas thread lower end.Packing groove, filler and drilling rod form sealing, and this part is supporting drill body, is subjected to pulling force during work.

(2) sleeve (drill body) is seen Fig. 3, buried bearing, guide block, bears the power that the bearing guide block transmits, and the side is equipped with ratchet and can be prevented guide block to rotate with drilling rod, plays a clamp dog and boosts the system of taking off and can rotate a back guide block with drilling rod.

(3) spanner is seen Fig. 6, and main spanner overcoat, ratchet Fig. 7, ratchet handle play clamp dog to be formed, and can move drilling rod, dextrorotation, dextrorotation.

(4) drilling rod sees that Fig. 8 acme thread lower end of matching with guide block is threaded.

(5) drill bit also can be an overman bit.Requirement is applicable to steel, the pig iron.

(6) guide block sees that Fig. 9 cooperates with drilling rod, moves on drilling rod during to right rotation (guide block fixedly time) drilling rod.The very heavy guide block of pull-up can change with drilling rod.

(7) bearing is selected thrust bearing or radial-thrust bearing for use.

(8) very heavy, see Figure 10, under the effect of spring, very heavy head enters can prevent the clockwise direction rotation in the breaker slot, and pull-up handle Rotate 180 ° makes very heavy break-in, then prevents the inverse time to rotation.

The utility model has the advantages that: volume is little, and is in light weight, saves material, and autofeed processing is easy, easy and simple to handle, time saving and energy saving, installs rapidly, and bore diameter is 20mm-200mm, and applicable situation is extensive.

Use special accessory or welding outer silk 33 is installed on trunk line 34 positions that need connect arm, outer silk is gone up gate 35 is installed, and (gate is installed and wanted firm ne-leakage, and can make the drill bit person of passing through) sees pipeline boring device (Fig. 1) for details.

The pipeline brill is installed on the gate, rotates spanner dextrorotation, ratchet is put down, guide block is fixed, and then rod bit moves down, and affacts on the tube wall, and guide block through bearing, sleeve, pipe thread joint, gate, affacts power on the pipeline at last.These devices all become pulling force.What drilling rod, drill bit obtained under the effect of guide block is pressure, therefore reaches the purpose of boring feed.The size of feed is controlled by ratchet, when feeling to move effort, can reverse clamp dog, ask unconventional system ratchet, break away from the breaker slot guide block and can rotate the turning in position of drill bit this moment with drilling rod, after turning over a week, move and feel laborsaving, ratchet played braking action guide block not only but also was fixed this moment, drill bit is feed again, carries out tube wall to be bored saturating so repeatedly automatically.It is then firmly also suitable to notice that appropriateness is grasped feed car pin.To hole beaten after, guide block is fixed, with the pull-up of spanner ratchet, Rotate 180 ° puts down, the spanner that turns left moves on the drilling rod, in the silk, closed shutter unloads brill, opens a sluice gate to dash remaining iron end then and closes outside drill bit falls back on pipe thread.
