Description

Marine fixed anchor fixes immersed tube device

Technical Field

The invention relates to offshore operation equipment, in particular to an offshore anchoring and sinking pipe fixing device.

Background

The anchoring and sinking pipe fixing at sea is a common method for offshore tunnel construction, anchoring is needed when the sinking pipe is fixed, most of anchoring devices in the prior art are connected insecure, drilling is carried out through a drill bit, and then anchoring nails are driven into the anchoring devices, so that the anchoring devices are very troublesome to install, the operation difficulty is increased at the sea bottom, and an improvement space exists.

Disclosure of Invention

The invention aims to solve the problems and provide an offshore anchoring and sinking pipe fixing device.

The invention realizes the purpose through the following technical scheme:

the invention comprises a drill bit, an outer sleeve, barb mounting slotted holes, an inner sleeve, a main shaft, a flange, a first rotating shaft, a connecting rod, a barb, a second rotating shaft and a third rotating shaft, wherein the lower end of the outer sleeve is detachably connected with the upper end of the drill bit, the side edge of the outer sleeve is provided with a plurality of barb mounting slotted holes, the inner sleeve is positioned in the outer sleeve, the inner sleeve is in threaded connection with the outer sleeve, the upper end of the main shaft is provided with the flange, the main shaft penetrates through the inner sleeve, the lower end of the main shaft is provided with the first rotating shaft, the first rotating shaft is in rotating connection with one end of the connecting rod, the lower end of the barb is in rotating connection with the upper end of the drill bit through the second rotating shaft, the middle section of a cutter head is provided with the third rotating shaft, and the other, the upper end of the inner cylinder is connected with drilling equipment.

Further, the upper end of the inner cylinder is connected with drilling equipment through a drill bit connection lug, and the drill bit connection lug is detachably connected with the inner cylinder.

Preferably, the drill bit connecting lug is detachably connected with the inner cylinder through a fixing bolt.

Preferably, the barbs are more than three barbs.

The invention has the beneficial effects that:

compared with the prior art, the device provided by the invention has the advantages that the drill bit is arranged for drilling, the drilling is directly performed in a forward rotation mode without knocking or replacing, and the anchoring can be completed in a reverse rotation mode, so that the difficulty of seabed operation is greatly reduced, the anchoring is firm, the use is convenient, and the popularization and application values are realized.

Drawings

Fig. 1 is a schematic structural view of the present invention.

In the figure: 1-drill bit, 2-outer sleeve, 3-barb installation slotted hole, 4-inner sleeve, 5-main shaft, 6-flange, 7-first rotating shaft, 8-connecting rod, 9-barb, 10-second rotating shaft, 11-third rotating shaft, 12-drill bit connecting lug and 13-fixing bolt.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1: the invention comprises a drill bit 1, an outer sleeve 2, a barb mounting groove hole 3, an inner sleeve 4, a main shaft 5, a flange 6, a first rotating shaft 7, a connecting rod 8, a barb 9, a second rotating shaft 10 and a third rotating shaft 11, wherein the lower end of the outer sleeve is detachably connected with the upper end of the drill bit, the side edge of the outer sleeve is provided with a plurality of barb mounting groove holes, the inner sleeve is positioned in the outer sleeve, the inner sleeve is in threaded connection with the outer sleeve, the upper end of the main shaft is provided with the flange, the main shaft penetrates through the inner sleeve, the lower end of the main shaft is provided with the first rotating shaft, the first rotating shaft is rotatably connected with one end of the connecting rod, the lower end of the barb is rotatably connected with the upper end of the drill bit through the second rotating shaft, the middle section of a cutter head is provided with the third rotating shaft, and the other end, the upper end of the inner cylinder is connected with drilling equipment.

Further, the upper end of the inner cylinder is connected with drilling equipment through a drill bit connecting lug 12, and the drill bit connecting lug is detachably connected with the inner cylinder.

Preferably, the drill bit connecting lug is detachably connected with the inner cylinder through a fixing bolt 13.

Preferably, the barbs are more than three barbs.

The working principle of the invention is as follows:

firstly, the main shaft is inserted from the upper end of the inner cylinder, passes through the lower end of the inner cylinder, then the inner cylinder is inserted into the outer sleeve, is connected with the outer sleeve by screw thread, the connecting rod is connected with the lower end of the main shaft, then the airing end of the connecting rod is rotatably connected with the middle section of the barb, then the drill bit is connected with the outer sleeve, the barb is rotatably connected with the upper end of the drill bit by a third rotating shaft, and finally the drill bit is connected with the drilling equipment by a drill bit connecting lug, when the drilling and anchoring are carried out, the drilling equipment drives the inner cylinder to rotate, the inner cylinder and the outer sleeve are screwed up through threads, so that the outer cylinder drives the drill bit to drill, when the drill hole is drilled to the required depth, the drilling equipment is reversely rotated, the inner cylinder and the outer sleeve are in threaded connection, the inner cylinder moves upwards, the rotating shaft is pulled to move upwards, the main shaft drives the connecting rod, the connecting rod jacks up the barb to extend outwards, and the barb jacks up the hole wall after the drill hole, so that the anchoring effect is achieved.

The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
