Abstract
The invention provides a multi-motor power head, which is a power component on a deep-hole long-spiral drilling machine in pile driving machinery. Three or four motors ensures that output power entersa main tooth box respectively through independent intermediate speed reducers, and then the three or four motors jointly drive a driven gearwheel with a hollow shaft arranged in the middle to rotate,wherein the hollow shaft has an outer diameter between 260 and 300 mm, a rotating speed of 5 rpm and a torque between 180 and 280 kNm, so as to continuously drive a drill rod to operate steadily andaccomplish the concrete casting task of a pile hole at the same time. The gross power output by the power head can reach 111 to 148 kw. The drilling machine using the power head can carry out concretepile foundation construction in a place that is complex in geological conditions, has geological conditions more than 1,500 mm and has a hole depth more than 30 m, which is suitable for the pile foundation construction of large-scale bridges or buildings.
Description
[technical field] the present invention relates to a kind of unit head, is a kind of multi-electric machine power head of deep hole long-spiral drilling machine specifically.
[background technology] is called for short three electric machine power heads by three motor-driven unit heads, by four motor-driven unit heads, is called for short four electric machine power heads.They are a kind of new type power heads.And available dynamic has only two motor-driven as first.In pile foundation engineering, when running into geological conditions complexity, aperture, use piling machinery construction with two motor-driven unit heads greater than the concrete pile hole of 1500mm, dark 30m, always feel unable to do what one wishes, wherein key is the unit head undercapacity.If construction reluctantly, otherwise motor is burnt, or drive disk assembly wearing and tearing too early or fracture, so that can't construct.
[summary of the invention] the invention provides a kind of multi-electric machine power head for adapting to the large aperture under complex geological condition, the pile foundation construction of deep hole, the difficult problem of unit head undercapacity when having piling machinery to large aperture, deep hole pile foundation construction now with thorough solution.
For solving its technical problem, the technical solution used in the present invention is: the multi-electric machine power head of designing comprises: motor, intermediate reduction gear machine, cardinal teeth case, high-efficiency sealing device, hollow shaft, guide rail card, concrete input pipe, erecting by overhang.Its feature is: 1. the cardinal teeth case is this unit head main body, three or four intermediate reduction gear machines is installed above it, the motor of same model is installed on each intermediate reduction gear machine, the gear wheel that the band hollow shaft is arranged in the cardinal teeth case, its periphery has three or four to be engaged with from the pinion that is positioned on the intermediate reduction gear machine output shaft, hollow shaft stretches out from the central authorities of cardinal teeth upper box part, its extension is connected with high-efficiency sealing device, and the sealing device is connected with the concrete input pipe again; The big pivot pin of erecting by overhang by screw rod with hang turbine shroud and combine and separate; The hollow section lower end is provided with flange, and is connected with hollow drill by this flange, thereby formation unit head and operating mechanism are an integral body of drilling rod.2. the external diameter of described hollow shaft is 260～300mm, and moment of torsion is 180～280kNm, and its rotating speed is 5rpm.3. described many motors are 3 or 4 slow-speed motors, and each power of electric motor is 37kw, and the general power of multi-electric machine power head output is 111～148kw.The ratio of the wide and length of 4. described guide rail card is 1: 2.
[description of drawings] the present invention is further described below in conjunction with the drawings and specific embodiments.
Accompanying drawing is the structural representation of the present invention's three electric machine power heads.
Among the figure: 1 slow-speed motor; 2 intermediate reduction gear machines; 3 cardinal teeth casees; 4 high-efficiency sealing devices; 5 hollow shafts; 6 guide rail cards; 7 concrete input pipes; 8 erectings by overhang.
[specific embodiment] embodiment: the unit head of three motors.
Referring to accompanying drawing, the hollow shaft 5 that to be provided with a diameter at the center of cardinal teeth case 3 be 280mm, the top of cardinal teeth case 3 is fixed with erecting by overhang 8, this erecting by overhang is a connector of hanging assembly pulley and unit head, its handwheel can make hangs the forward/back easily of big pivot pin, the lower end of hollow shaft 5 is provided with flange, be connected high-efficiency sealing device 4 by bolt with hollow drill (not drawing among the figure) and be installed in the cardinal teeth upper box part, the other end of concrete input pipe 7 passes sealing device 4 and combines with the hollow shaft epimere, can make high pressure concrete carry out a hole by the through stake of hollow drill hole fills, the middle part of hollow shaft is equipped with driven gear wheel, thereby making hollow shaft is 5rpm with the rotating speed, moment of torsion is the 180kNm rotation and continuously drives the drilling rod balanced operation, be provided with two groups of guide rail cards 6 hanging on support and the cardinal teeth case side, in order to allow the unit head assembly slide on boring mast (not drawing in the accompanying drawing), the ratio of the wide and length of this guide rail card is 1: 2; The slow-speed motor 1 that described power assembly is 37kw by three power of vertical structure, each motor is formed by intermediate reduction gear machine 2 and cardinal teeth case 3 that adapter sleeve connects, the driver pinion of installing on each intermediate reduction gear machine 2 output shaft, driven gear wheel engagement in cardinal teeth case 3 and on the hollow shaft, thereby drive the hollow shaft rotation, the output general power of this unit head is 111kw.
Its course of work is: with reference to accompanying drawing: connect power supply by rules, connect drilling rod, and make drilling rod be in the state of spudding in, check each attachment screw of unit head once more, whether each lubricating system is normal.After above-mentioned work is carried out, can start three motors 1 simultaneously, three motors 1 are connected with separately intermediate reduction gear machine 2 by adapter sleeve again, be equipped with on the output shaft of intermediate reduction gear machine 2 driver pinion and with hollow shaft on gear wheel engagement, drilling rod carries out operation thereby 5 rotations of driving hollow shaft, hollow shaft 5 directly link again.High-efficiency sealing device 4 is equipped with on hollow shaft 5 tops, to guarantee the unlikely infiltration cardinal teeth of high pressure concrete case 3, wide and the length of guide rail card 6 through being 1: 2, guaranteed that unit head slides freely on the guide rail that bores mast, big pivot pin in the erecting by overhang 8 adopts hand screw to send the scheme of withdrawing to, makes it laborsaving, quick, reliable.
