Detailed Description
The utility model discloses an anchor clamps device accessible chuck combines with harness 4 of utensil fixer, realizes self-holding and loosens the probe rod, need not manpower manual regulation chuck.
The utility model discloses an anchor clamps device mainly includes two chucks, and every chuck includes a little metal block 3, has a inside metal contact 2 and the metal friction plate 1 that has spring 8 on little metal block 3, and there is triangle-shaped arch 5 little metal block 3's both sides, and 3 outsides of little metal block are surrounded by a big metal block 9, and great metal block leans on recess 7 to agree with mutually with little metal block 3's triangle-shaped arch 5, and the recess combines with the arch, confirms little metal block 3's removal orbit. The big metal block 9 is wide at the top and narrow at the bottom to form a wedge shape. The large metal block has a projection 10 for limiting the up-down movement range of the small metal block 3. When in use, the clamping heads are arranged in a metal harness and then fixed with the harness fixer 4, and the harness can drive the two clamping heads to move up and down to penetrate the probe into the soil or pull the probe out of the soil. The small metal block moves smoothly in the large metal block through the inclined plane and the lubricant on the inclined plane, so that the blocking effect of the chuck when clamping the probe rod and releasing the probe rod is smaller.
And a probe rod penetrating stage: as shown in FIG. 4, the A ends of the two penetration heads are put into the fixture and then the fixture 4 is put into the fixture. The harness lifts the chuck to the highest point, and the metal contact head 2 is contacted with the probe rod. When the chuck descends, due to the friction action of the metal contact 2 and the pipe wall, the small metal block 3 slides to the end A in the groove 7 through the protrusions 5 on the two sides, at the moment, the metal contact 2 contracts inwards (a spring is arranged in the metal contact 2), the metal friction plate 1 is in contact with the pipe wall, the friction force is increased, and the probe rod is clamped tightly. The friction force enables the small metal block 3 to have the tendency of continuously moving towards the end A, so that the probe can be ensured to be tightly clamped by the penetration head, and the probe can be penetrated into the ground by the penetration head with enough friction force. When the chuck reaches the lowest end, it will rise. At this moment, under the effect of frictional force, little metal block 3 can slide to the direction of keeping away from the A end through recess 7 of both sides, reduces with pipe wall frictional force, and metal friction plate 1 breaks away from the contact with the pipe wall, only metal contact 2 and pipe wall contact, and the penetration head can rise under the drive of harness, because contact head and probe rod frictional force are less than probe rod gravity this moment, so can not take the probe rod out. And (4) circulating the process until the chuck rises to the highest point, so that the probe rod is continuously penetrated into the soil.
Pulling out a probe rod: when the probe is lifted by the gripping head, the holder 4 is first removed, the two handles 6 of the penetration head are turned so that the end A faces downward, and the holder is then placed (see FIG. 5). When the chuck is from upwards promoting down, because the frictional force of metal contact 2 department, can make little metal block 3 slide to the A end along recess 7, metal contact 2 is inwards shrink (2 are middle and old to have the spring) this moment, and metal friction plate 1 makes the frictional force increase with the pipe wall contact to press from both sides the probe rod tightly. The friction force enables the small metal block 3 to have the tendency of continuously moving towards the end A, so that the probe rod can be tightly clamped by the clamping head, and the probe rod can be pulled out from the ground by the friction force. When the chuck rises to the highest point, the chuck is driven by the harness to descend. At this moment, under the effect of frictional force, little metal block 3 can slide to the direction of keeping away from A through the recess 7 of both sides, and metal friction plate 1 separates with the pipe wall, only metal contact 2 and pipe wall contact reduce with pipe wall frictional force, because the frictional action of soil, when chuck and probe rod frictional force reduce, the probe rod can not fall back original degree of depth yet. And repeating the above processes until the probe descends to the lowest point, and continuously pulling out the probe rod.
And finally, pulling out the probe rod, taking down the probe, and connecting a computer to obtain test data and process the test data.
Conventional penetration techniques require manual release of the probe to replace the topmost clamp when the bottommost end is reached. And this utility model relies on the inclined plane, can let the chuck press from both sides tightly in appropriate time and relax, with the chuck inject in succession or extract, has very big improvement to the convenience of engineering.
The density of the soil body is increased along with the increase of the depth, and the structure of the inclined plane can ensure that the resistance of the soil body is larger, and the clamping head clamp is tighter, so that the probe can be smoothly penetrated into the soil body to read data, and the structure has important significance for practical engineering.
