The embodiment discloses an expansion bolt drawing instrument, which comprises a hand pump, a hollow hydraulic cylinder, a high-pressure oil pipe, an oil pressure gauge, a pull rod, a wheel disc and a plurality of adapters in different specifications, and is shown in the figures 1 to 4.

The high-pressure oil pipe is connected with the manual pump and the hollow hydraulic cylinder, oil can be supplied to the hollow hydraulic cylinder by pressing the manual pump, and a piston rod of the hollow hydraulic cylinder extends out of the cylinder body along with the improvement of oil pressure. The oil pressure gauge is arranged on the manual pump to display oil pressure.

The wheel disc is welded with a supporting shaft. The axis of the supporting shaft is coincident with the axis of the wheel disc. The mounting seat is arranged on the outer wall of the cylinder body of the hollow hydraulic cylinder and specifically comprises two fixing blocks welded on the outer wall of the cylinder body. The support shaft penetrates through the two fixing blocks and limits axial movement of the two support shafts through the clamp springs. The circlip is not shown in the figure. The wheel disc is attached to the opposite surface of the hollow hydraulic cylinder and the wheel disc is completely attached to the surface of the hollow hydraulic cylinder facing the wheel disc.

The wheel disc is provided with a plurality of accommodating holes which are through holes. The plurality of receiving holes are equally spaced about and parallel to an axis of the wheel disc. The distance between the axes of the containing hole and the wheel disc is equal to the distance between the axes of the hollow hydraulic cylinder and the wheel disc. The wheel disc is further provided with a plurality of weight reduction grooves, and each weight reduction groove is located between the adjacent accommodating holes.

Each accommodating hole is internally provided with an adapter. The adapter is cylinder structure. First connecting holes and second connecting holes are formed in two end faces of the adapter respectively and are threaded holes and coaxial. The first connecting hole and the second connecting hole are parallel to the accommodating hole. The first connecting hole is used for connecting with the pull rod, and the second connecting hole is used for connecting with the expansion bolt. The second connecting holes on different adapters have the same hole diameter, so that different adapters can be connected with different expansion bolts.

The outer wall of the adapter is integrally formed with a flange, and the diameter of the flange is consistent with the aperture of the accommodating hole. Two annular baffles are welded and fixed in the accommodating hole, the adapter penetrates through the two baffles, the two baffles are respectively positioned on two sides of the flange, and the thickness of the flange is smaller than the distance between the two baffles. The adapter can be in its axial displacement of holding downthehole edge but the displacement receives the restriction of baffle, and the adapter does not stretch out from the holding downthehole.

The adapter still integrated into one piece has two lugs, and the lug is located the one end that the adapter is close to the pull rod to the lug does not stretch out from the holding hole. Two lugs are respectively located the opposite sides of the adapter, and the lugs can facilitate people to rotate the adapter.

The specific implementation process of this embodiment is as follows: and selecting the adapter matched with the expansion bolt to be tested, abutting the wheel disc on the wall surface and screwing the adapter to enable the expansion bolt to be screwed into the second connecting hole. And further rotating the hollow hydraulic cylinder around the supporting shaft to enable the hollow part of the hollow hydraulic cylinder to be opposite to the expansion bolt to be tested, and extending the pull rod from the hollow part and screwing the pull rod and the adapter together until the disc of the pull rod is abutted against the hollow hydraulic cylinder. After the above-mentioned actions are completed, the subsequent measurement operation can be carried out. And when the expansion bolts of different specifications need to be measured, only a suitable adapter needs to be found on the wheel disc. At this in-process, all adapters are all on the rim plate, have the beneficial effect of being convenient for arrange in order and collect, also are difficult for losing, also need not to reach the instrument set simultaneously and put the department and take, and it is more convenient at the field operation.
