Detailed Description
The invention discloses an embodiment of a detachable drill bit for adjusting the height of a nut in a building jacking, which comprises the following steps:
the specific structure of the detachable drill bit for adjusting the height of the nut in the building jacking is shown in fig. 1 to 3, and comprises a sleeve 1, wherein the upper end of the sleeve 1 is provided with an electric wrench matching end 11 for connecting the head of an electric wrench 5, the lower end of the sleeve 1 is fixed with a support frame 2, the lower end of the support frame 2 is fixed with a positioning rod 3, and the positioning rod 3 is coaxial with the sleeve 1. A driving rod 4 is fixed at the lower end of the supporting frame 2 outside the positioning rod 3.
The jacking 6 comprises a jacking main body 61 and a jacking nut 62, and the jacking nut 62 is sleeved outside the jacking main body 61 in a threaded manner. One end of the jacking main body 61 is fixed with a chassis 63, and the other end is provided with a positioning hole 64, wherein the positioning hole 64 is coaxial with the jacking main body 61. The distance between the drive rod 4 and the positioning rod 3 is smaller than the radius of the jacking nut 62.
When the height of the top nut 62 needs to be adjusted downward, the upper end of the socket 1 is fixed to the head of the electric wrench 5, the positioning rod 3 is inserted into the positioning hole 64, and the driving rod 4 is abutted against the outer contour surface of the top nut 62. The positioning rod 3 and the support frame 2 cooperate to limit axial movement and circumferential rotation of the jacking main body 61, the driving rod 4 is driven by the electric wrench 5 to rotate around the positioning rod 3, and the jacking nut 62 in threaded connection with the jacking main body 61 can generate axial movement relative to the jacking main body 61 when rotating around the jacking main body 61, so that the effect of adjusting the position of the jacking nut 62 on the jacking main body 61 can be achieved. The raising and lowering of the jacking nut 62 can be achieved by changing the steering direction of the electric wrench 5. When the jacking nut 62 moves to be flush with the lower end of the driving rod 4, the driving rod 4 can not be abutted with the outer side surface of the jacking nut 62 any more, so that the jacking nut 62 can not be driven to move downwards along the axial direction continuously. The extreme position of the lower row of the jacking nuts 62 is at the lower end face of the drive rod 4.
In this embodiment, the driving rod 4 includes an upper rod 41, a sleeve 42 and a lower rod 43, which are coaxially connected, the upper end of the sleeve 42 is provided with a first thread section that is completely matched with the thread feature of the lower end of the upper rod 41, the lower end of the sleeve 42 is provided with a second thread section that is completely matched with the thread feature of the upper end of the lower rod 42, and both the upper rod 41 and the lower rod 43 are coaxially inserted into the sleeve 42 to form the driving rod 4. The length of the driving rod 4 can be adjusted by adjusting the connecting length of the upper rod 41 and the sleeve 42 and the connecting length of the lower rod 43 and the sleeve 42, so that the lower limit position of the jacking nut 62 on the jacking main body 61 can be adjusted. In other embodiments, either of the upper rod 41 and the lower rod 43 may be fixed together with the sleeve by welding or gluing or directly integrated, in which case there is no need to provide an external thread section on the corresponding rod body or to provide an internal thread section at the corresponding end of the sleeve 42.
In this embodiment, the sleeve 1, the support frame 2, the positioning rod 3, and the upper rod 41 are welded. The support frame 2 is made of two round steel bars through welding. In other embodiments, the sleeve 1, the support frame 2, the positioning rod 3 and the driving rod 41 can be fixed together in other manners; the support frame 2 may be formed in other shapes as long as it has a position for connecting the sleeve 1, the positioning rod 3, and the upper rod 41.
In a more preferred embodiment, the length of the sleeve 42 is equal to the sum of the length of the lower threaded section of the upper rod 41 and the length of the upper threaded section of the lower rod 43, and the length of the first threaded section is equal to the length of the lower threaded section of the lower rod 41. In this case, the threaded section of the upper rod 41 can be screwed completely into the sleeve 42 to increase the strength of the connection between the upper rod 41 and the sleeve 42. It will be understood, of course, that the length of the first threaded segment may be greater or slightly less than the length of the threaded segment at the lower end of the upper shaft 41, which may result in a portion of the threaded segment not being able to perform the cooperative locking function, but does not affect the adjustment of the length of the drive shaft 4 in the present invention.
In a more preferred embodiment, two driving rods 4 are provided, and the two driving rods 4 are symmetrically distributed on both sides of the positioning rod 3. Under the arrangement mode, the two driving rods 4 are uniformly stressed, so that the driving rods 4 have the advantages of high strength and difficulty in breaking. It can be understood that only one driving rod 4 may be provided, which does not affect the function of adjusting the height of the jacking nut 62 by using the present invention, but has the problems of uneven stress and easy damage of the driving rod.
In a more preferred embodiment, either one of the positioning rod 3 and the driving rod 4 can be mounted at the lower end of the supporting frame 2 in a manner of circumferential rotation and axial stopping. Of course, it can be understood that the fixing of the positioning rod 3 at the lower end of the supporting frame 2 does not affect the insertion of the positioning rod 3 into the positioning hole 64 for positioning, but the positioning rod 3 rotates with the rotation of the electric wrench 5 to rotate relative to the positioning hole 64; the driving rod 4 is fixed at the lower end of the supporting frame 2, and the rotation of the jacking nut 62 pushed by the rotation of the electric wrench 5 around the positioning rod 3 cannot be influenced.
