Technical Field
The utility model relates to a pipe joint stock draw-off gear especially relates to a stock draw-off gear that is used for pipe joint stock anchor power to test.
Background
As the tubular seam anchor rod pulling device of prior art usually the structure is more complicated, and installation and demolish time are long, and not only work efficiency is low, and when the operation personnel was tested in the field in the pit, the longer risk was big more when using. On the other hand, when the pipe seam anchor rod drawing device in the prior art is used for carrying out anchor rod drawing tests, the anchor rod ring of the pipe seam anchor rod is often stressed unevenly, the anchor rod ring of the pipe seam anchor rod is easy to break, and the test result is inaccurate, so that the pipe seam anchor rod drawing device which is simple in structure, quick to disassemble and assemble and accurate in test has great practical significance.
Disclosure of Invention
The utility model aims to solve the technical problem that a tube seam stock anchor force test is with draw-off gear is provided, has simple structure, quick assembly disassembly, tests accurate characteristics for overcome that traditional tube seam stock draw-off gear structure is complicated, the installation with demolish the long, unsafe shortcoming of test result of time.
The technical scheme of the utility model as follows:
the drawing device for the anchoring force test of the pipe seam anchor rod comprises a fixed sleeve and a traction pull rod, and is characterized in that the fixed sleeve is provided with a radial gap for placing the pipe seam anchor rod and an anchor rod ring, and the fixed sleeve is also internally provided with an annular groove for accommodating the anchor rod ring; the fixed sleeve is also provided with a threaded opening positioned outside the annular groove, and a traction sleeve is arranged in the threaded opening; the rear end of the traction sleeve is connected with the traction pull rod.
Preferably, the front end of the traction sleeve is provided with a pattern conical head.
Preferably, the drawing device further comprises an observation sleeve with an observation hole formed in the side wall; one end of the observation sleeve is open, and the other end of the observation sleeve is provided with a through hole for penetrating through the traction pull rod.
Compared with the prior art, the utility model discloses following positive effect has:
first, when drawing the test, the utility model discloses pull the conical head of cover front end and tightly fix the tube seam stock and anchor rod ring between fixed cover and traction cover, the step through the ring channel is even to anchor rod ring application of force, and anchor rod ring circumference atress is difficult to the fracture.
Second, the utility model discloses set up the observation cover that the observation hole was seted up to the lateral wall among the optimization technical scheme. The stress deformation condition of the anchor rod ring can be observed in real time on the premise of ensuring the safety of field test operation.
The utility model discloses still have simple structure, can be fast, the accurate characteristics of test tube seam stock anchor power.
Drawings
Fig. 1 is an external schematic view of a first embodiment of the present invention.
Fig. 2 is a schematic structural diagram of a first embodiment of the present invention.
Fig. 3 is an external view of the second embodiment of the present invention.
1. The pipe seam anchor rod comprises a pipe seam anchor rod body 11, an anchor rod ring 2, a fixing sleeve 21, an annular groove 3, a traction sleeve 4, a traction pull rod 5, an observation sleeve 51 and an observation hole.
Detailed Description
The present invention will be further described with reference to the following embodiments and accompanying drawings.
Example one
As shown in fig. 1 and 2, the embodiment of the present invention includes a fixing sleeve 2, the fixing sleeve 2 is provided with a radial notch for placing the pipe seam anchor rod 1 and the anchor rod ring 11, and the fixing sleeve 2 is further provided with an annular groove 21 for accommodating the anchor rod ring 11. When in use, the annular step at the left side of the annular groove 21 is used for clamping the anchor rod ring 11 from the left side, and when the fixed sleeve 2 is subjected to rightward drawing force, the annular step applies force to the anchor rod ring 11 from the left side to the right side. The fixed sleeve 2 is also provided with a threaded opening which is positioned outside the annular groove 21 (namely, on the right side), a traction sleeve 3 is installed in the threaded opening in a threaded connection mode, the front end of the traction sleeve 3 is used for being propped against the end part of the pipe seam anchor rod 1, and the rear end of the traction sleeve is in threaded connection with a traction pull rod 4. The front end of the traction sleeve 3 is provided with a pattern conical head.
Example two
As shown in fig. 2 and 3, in the first embodiment, the present embodiment further includes an observation sleeve 5 having a side wall provided with an observation hole 51. One end of the observation sleeve 5 is open, and the other end is provided with a through hole for penetrating the traction pull rod 4.
During testing, the anchor rod ring 11 is firstly aligned to the annular groove 21, the outer end part of the pipe seam anchor rod 1 and the anchor rod ring 11 at the outer end part enter the fixing sleeve 2 through the radial gap, and the anchor rod ring 11 is ensured to be positioned in the annular groove 21. Then the traction sleeve 3 is rotated to enable the traction sleeve 3 to be in threaded fit connection with the threaded opening section of the fixed sleeve 2, and in the process that the traction sleeve 3 enters the fixed sleeve 2, the patterned conical head at the front end of the traction sleeve 3 tightly fixes the pipe seam anchor rod 1 and the anchor rod ring 11 between the fixed sleeve 2 and the traction sleeve 3. Then the traction pull rod 4 is rotated to connect the front end of the traction pull rod 4 with the threaded hole at the rear end of the traction sleeve 3. And then the observation sleeve 5 is installed by pulling the pull rod 4 to penetrate through the through hole, so that the open end of the observation sleeve 5 is pressed against the rock surface of the installation tubular seam anchor rod 1. And finally, drawing and pulling the traction pull rod 4 by using an oil cylinder dynamometer, and testing the anchoring force of the pipe seam anchor rod 1. The drawing can be observed through the observation hole 51 during the drawing.
After the test is finished, firstly taking down the observation sleeve 5, then taking down the traction sleeve 3 by the rotation of the wrench, and finally separating the traction sleeve 3 and the traction pull rod 4 by rotating the wrench to finish the whole process of the dismounting work of the quick pipe seam anchor rod drawing device.
