Abstract

The utility model provides a portable steel rail driller specially used for the railway, which is composed of an n-shaped angle steel drill rig, an electrical machine, adjusting screws, an adjusting plate and a water box on the upper part of the drill rig, wherein, the rear part of the electrical machine is connected with a trapezoidal screw rod; the front part of the electrical machine is fixed with a drill head through a drill sleeve. Because the drill rig of the utility model is welded by angle steel, the utility model can drill holes only by putting the drill rig on a proper position of a steel rail without needing special fixing machines. The stability of the integral machine is good, and the position of the hole is precise. Because the drill sleeve is adopted to fix the drill head, the drill head is arranged tightly. The water box water automatically, and solves the problem that a special person is needed to water to cool. The utility model has the advantages of small size of the integral machine, light weight, convenient carry and simple technology, and the cost is reduced by 20%-30%.

Description

Portable serial steel rail driller

The utility model relates to a kind of rail bonding drill of railway special use, especially a kind of portable serial rail bonding drill.

Along with developing rapidly of railway electrification level, signalling arrangement is brought in constant renewal in, and no matter is newly-built or to the transformation of old signalling arrangement, all be unable to do without the setting of track circuit, and track circuit is set, and just must on rail, bore a large amount of lead plug pin holes, connect line in order to installation.On rail, hole, five, the sixties adopt ratchet drill manually to hole, it is an arduous and inefficient construction method, the seventies gradually adopts foot-operated or the artificial drilling machine of hand-rail type, and the eighties begins to adopt electronic drilling machine again, but electric rail drill hole machine is owing to use aluminum casting to do the drilling cramp main body, manufacturing process, complex structure, cost height, poor durability, the complete machine job stability is bad, influence the quality in hole, it uses common electrical drill chuck to be difficult for dress again and gets drill bit, the working site can not be at any time abrasive drilling head on the spot, also must there be a people to water the water cooling drill bit specially, influence operating efficiency, and complete machine weight is big, inconvenience is carried.

The purpose of this utility model provides a kind of boring work that can be applicable to all kinds rail, adopts the angle steel structure, no consumable accessory, easily fixing, good stability, convenient firmly dress is got drill bit, installed the automatic watering function box additional, the portable serial rail bonding drill that complete machine is small and exquisite, light.

The utility model is by Jiong type drilling cramp, trapezoidal screw, motor, slide bar, drill bushing, drill bit and adjust plate, adjust screw, water box etc. forms.

Further describe below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

The drilling cramp (1) of this portable serial rail bonding drill adopts Jiong type slotted-angle shelving, be fixed with two in the middle and be convenient to the slide bar (4) that motor (3) seesaws, slide bar (4) is being overlapped on motor (3) both sides, the rear portion connects a trapezoidal screw (2), and is anterior by drill bushing (5) fixed drill bit (6).There is the adjustment screw (7) that props up chucking rail (11) front portion of Jiong type drilling cramp (1) and adjusts plate (8), and top is fixed with a water box (9), and (10) are water box switch.This rig adopts AC/DC pistol electric drill as boring power, adopts trapezoidal screw capstan handle turn propulsion electric machine, takes the anterior upper and lower rail side that props up simultaneously to offset the method for propulsive force, makes the complete machine working stability and need not the firm drilling cramp of external force.In addition, also be furnished with a miniature husky wheel and supply at the scene abrasive drilling head usefulness at any time.

The rig course of work: (1) will confirm institute's drill steel rail type before using, and will adjust screw again and adjust plate to transfer to the relevant position.(2) with the derotation of augering screw handle, motor is pulled to the rear portion, loads onto drill bushing, drill bit.(3) the drilling cramp front portion is placed in the rail appropriate location.(4) dextrorotation screw handle makes drill bit withstand the rail wall.(5) after adding water, the water box gets final product starter motor.(6), can begin boring with the direct turn capstan handle of hand propulsion electric machine.

This Portable rail drilling machine is compared with the drilling machine of present use, and advantage is remarkable: the drilling cramp main body is the angle steel Welding Structure, and manufacturing process is simple, no easily worn part. Applicability is strong, as long as adjust a little, just can be applicable to the boring work of all kinds rail. Need not specially fixedly drilling cramp machinery, parts, as long as drilling cramp is placed on the rail appropriate location, mixes up and adjust plate and adjust screw, can operate boring, advance in the brill process, complete machine stability is good, and the position in hole is accurate, and the quality in hole obviously improves. This drilling machine is cancelled common chuck, takes the method for drill bushing fixed installation straight shank drill, has fundamentally solved the shortcoming that drill bit easily relaxes, and simple and convenient firm dress is provided, gets the Perfected process of drill bit. And be equipped with a miniature sand round, get final product on the spot at the scene crusher drill, for a large amount of borings have improved operating efficiency effectively. Install automatic watering function cooling drill bit device additional, solved the problem that to water the water cooling drill bit with the special messenger. Overall design is small and exquisite, and is light, is easy to carry, and BX-1 type machine length overall is 60cm only, wide 13.6cm, high 26cm, heavy 8kg. BX-2 type machine length overall 70cm, wide 17cm, high 28cm, heavy 12.5kg, people's one hand can carry easily. Manufacturing process is simple, durable, cost 20～30%.
