Abstract

The present invention relates to a casing rotator having a reverse-circulation bedrock-crushing function and, more particularly, to a casing rotator capable of performing a reverse-circulation bedrock-crushing function, which crushes a bedrock. A casing rotator according to the present invention comprises a casing, a plurality of drill rod pipes, a key plate, and a rotator assembly means. The drill rod pipes are assembled in a row, are inserted into the casing, and are coupled to the lower portion of a swivel. The key plate is detachably coupled to an end of the drill rod pipes. The rotator assembly means comprises a reduction gear unit, which reduces the driving rate of a driving motor and transfers the same, a clamp body, which has a through-hole formed therein such that the casing can be inserted therein, and which is coupled to the reduction gear unit such that the same can be rotated by the reduction gear unit, a casing grasping unit, which is inserted into one side of the through-hole of the clamp body, and which can grasp the casing, and a pipe grasping unit, which is inserted into the other side of the through-hole of the clamp body, and which can grasp the key plate. According to the present invention, the casing rotor has a reverse-circulation bedrock-crushing function, making any separate reverse-circulation bedrock crusher unnecessary. Accordingly, a task of rotating the casing, soil discharging, and bedrock digging can be processed by a single piece of equipment. As a result, the working time is reduced, and, since no separate equipment needs to be purchased, the initial investment cost is low. In addition, noise generated on the spot is substantially reduced, and consistent soil discharging can be accomplished, thereby improving working efficiency.

케이싱 로테이터는 기초 공사용 장비로서, 케이싱을 땅 밑으로 박아 넣는 여러가지 장비 중 하나이다. 비교적 케이싱의 수직도를 확보하기가 용이하여 건설공사 현장에서 선호되어 왔으나, 동일한 작업을 행하는 케이싱 오실레이터에 비하여 장비가격이 고가이고, 또 토크나 압입, 인발력 등이 크지 않아 복합지질 조건에 따른 중부하가 요구되는 공사현장에서는 외면 받아 왔다.The casing rotator is a basic construction equipment and is one of several equipments for driving the casing to the ground. Although it is relatively easy to secure the verticality of the casing, it has been preferred at construction sites, but the equipment price is higher than that of the casing oscillator which does the same work, and the heavy load according to the complex geological conditions is not high. The construction site where is required has been rejected.

Drained pieces of rock were discharged.
즉 종래의 경우에는 케이싱 로테이터를 사용하여 케이싱 작업을 한 후 케이싱 로테이터를 제거하고 그리고 역순환 굴반기를 사용하여 암반굴착 및 토사 배출작업을 해야만 한다. 따라서 종래의 경우에는 케이싱 로테이터와 역순환 굴반기를 모두 구비해야 하므로 장비 구입비용이 비싸서 초기 투입비용이 높아지고, 이들 모든 장비를 현장에 투입해야 하므로 작업시간이 길어질 뿐만 아니라 현장에서 작업효율이 높지 않다는 문제점이 있었다.That is, in the conventional case, the casing rotator must be used to remove the casing rotator, and the reverse circulation excavator should be used for rock excavation and earth discharge. Therefore, in the conventional case, since both the casing rotator and the reverse circulator must be provided, the initial purchase cost is high due to the expensive equipment purchase cost, and all the equipment must be put on site, resulting in not only long working time but also high efficiency in the field.

로테이터조립수단(30)은 드릴로드파이프(12) 또는 케이싱(10)을 회전시키는 역할을 한다. 이를 위하여 로테이터조립수단은 감속기어부(31)와, 클램프바디(33)와, 케이싱파지부(35) 및 파이프파지부(39)를 구비한다.Rotator assembly means 30 serves to rotate the drill rod pipe 12 or the casing (10). To this end, the rotator assembly means includes a reduction gear portion 31, a clamp body 33, a casing gripping portion 35 and a pipe gripping portion 39.
감속기어부(31)는 구동모터(미도시)에 의하여 동작하며 구동모터의 구동속도를 감속하여 전달한다. 이때 감속기어부(31)은 2단으로 감속할 수 있는 것이 바람직하다. 즉 케이싱(10)을 회전시킬 때에는 고토크를 얻기 위하여 저속으로 구동하고, 드릴로드파이프(12)를 회전시킬 때에는 고속으로 구동한다.The reduction gear unit 31 is operated by a driving motor (not shown) and transmits the driving speed of the driving motor by decelerating. At this time, it is preferable that the reduction gear unit 31 can be decelerated in two stages. That is, when the casing 10 is rotated, it is driven at a low speed to obtain high torque, and when the drill rod pipe 12 is rotated, it is driven at a high speed.
클램프바디(33)는 내부에 케이싱(10)이 삽입될 수 있는 관통공(34)이 형성되고, 감속기어부(31)로 회전할 수 있게 감속기어부(31)에 결합되며 상부프레임(20)에 회전할 수 있게 지지된다. 이때 관통공(34)은 하부는 케이싱파지부(35)의 웨지클램프(36)가 삽입될 수 있도록 경사져서 형성되고, 상부는 파이프파지부(39)의 고정블럭(40)이 삽입될 수 있도록 경사져서 형성된다.The clamp body 33 has a through hole 34 into which the casing 10 can be inserted, and is coupled to the reduction gear part 31 so as to rotate with the reduction gear part 31, and to the upper frame 20.

To this end, the casing gripping portion 35 includes a wedge clamp 36 and a clamp constraining member 38. The wedge clamp 36 is inserted into the lower portion of the through hole 34 of the clamp body 33. The clamp constraining member 38 serves to insert the wedge clamp 36 into the through hole 34 of the clamp body 33 so that the wedge clamp 36 can grip the casing 10. To this end, the clamping member 38 is formed of a clamping cylinder, one end of which is fixed to the lower frame 22 and the other end of which is fixed to the upper frame 20. Thus, when the clamping cylinder is contracted, the wedge clamp 36 may be inserted into the through hole 34 of the clamp body 33 to fix the casing 10. When the clamping cylinder is extended, the wedge clamp 36 is lowered and the casing ( 10).
파이프파지부(39)는 드릴로드파이프(12)를 회전시킬 수 있도록 드릴로드파이프(12)를 파지하는 역할을 한다. 이를 위하여 파이프파지부(39)는 고정블럭(40)과, 결합고리(42) 및 고정덮개(44)를 구비한다.The pipe gripping portion 39 serves to grip the drill rod pipe 12 to rotate the drill rod pipe 12.

In addition, the fixing block 40 has a key groove 40a on which the key plate 14 can be inserted to be inserted. Both the key plate 14 coupled to one end of the drill rod pipe 12 and the key plate 12a formed at an intermediate portion of the drill rod pipe 12 may be inserted into the key groove 40a. In addition, the fixing block 40 is formed with a key passing hole 40b penetrated in a direction perpendicular to the key groove 40a so that the key plate 12a can be inserted therethrough. That is, even when the fixing block 40 is mounted, the drill rod pipe 12 in which the key plate 12a is formed may be inserted into the casing 10 through the key passing hole 40b.
결합고리(42)는 고정블럭(40)을 클램프바디(33)에 고정시키는 역할을 한다. 이를 위하여 결합고리(42)는 일단은 상부프레임(20)에 결합되고 타단은 고정블럭(40)에 결합될 수 있다. 그래서 고정블럭(40)을 클램프바디(33)의 관통공(34)에 삽입시킨 후 결합고리(42)를 고정블럭(40)에 결합시키면 고정블럭(40)은 클램프바디(33)와 일체로 회전할 수 있다.Coupling ring 42 serves to fix the fixed block 40 to the clamp body (33). To this end, the coupling ring 42 may be coupled to one end of the upper frame 20 and the other end of the coupling ring 42 to the fixed block 40. Thus, after the fixing block 40 is inserted into the through hole 34 of the clamp body 33 and the coupling ring 42 is coupled to the fixing block 40, the fixing block 40 is integrally formed with the clamp body 33. Can rotate
고정덮개(44)는 키홈(40a)에 키플레이트(14, 12a)가 삽입된 경우 키플레이트(12a, 14)를 덮을 수 있도록 고정블럭(40)에 탈착할 수 있게 결합된다.The fixing cover 44 is detachably coupled to the fixing block 40 so as to cover the key plates 12a and 14 when the key plates 14 and 12a are inserted into the key grooves 40a.
