Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement-based grouting fullness detection, in particular to an assembled cement-based grouting fullness tube. Background Art
[0002] When testing the fullness of cement-based mortar, a mortar fullness tube tester is required. The mortar fullness tube tester has a transparent organic glass tube with an inner diameter of 40 mm, a straight tube angle of 120° at both ends, and a length of 0.5 m for each part. The two parts are sealed and bonded by adhesive or connected by flanges and bolts. Place the organic glass tube on a fixed frame. During the test, after mixing the slurry according to the prescribed method, let it stand for 1 minute, and then pour the slurry into the fullness tube fixed on the fixed frame through a flow cone. After filling the slurry, seal both ends of the circular tube with plastic film. Let it stand at 20℃±3℃, and observe whether there are air bags with a diameter greater than 3 mm inside the tube, or whether there are water bags or water vapor, and whether there are foam layers at both ends of the pipe. Fullness determination: If there is a foam layer with a thickness of more than 1 mm, or an air bag with a diameter greater than 3 mm, or a water volume greater than 1 mL, the fullness index is judged to be unqualified.
[0003] However, the existing cement-based grouting filling tube is generally sealed and bonded with adhesives or connected by flanges and bolts, which makes the assembly and disassembly of the filling tube more troublesome and inconvenient. When a straight tube is damaged, it needs to be completely replaced, which causes waste. In addition, when placed on a fixed frame, there is no limit on the top, which makes the filling tube easy to move up and down and affect the accuracy of the test. Therefore, we propose an assembled cement-based grouting filling tube to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the above-mentioned shortcomings and proposes an assembled cement-based grouting filling tube.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, the two extrusion springs are respectively sleeved on the outer sides of the corresponding pull rods.
[0013] Preferably, the two lifting plates are slidably mounted in the corresponding cavities respectively.
[0014] When the locking cam is in contact with the flange on the rear side, the two locking cams are automatically pressed back into the sliding groove and the return spring is pressed, thereby not hindering the locking cam from being fully inserted into the two sockets. When the return spring is in contact with the flange on the rear side, the two locking cams are just not pressed. Under the elastic force of the return spring, the two locking cams extend out and are clamped on one side of the flange on the left side, thereby connecting the two flanges together and connecting the two straight pipes to form a filling pipe. When disassembling, the two locking cams are pressed to retract the two locking cams into the sliding groove without fixing the locking cams. At this time, the locking cams can be pulled out without fixing the two flanges, and the two straight pipes can be disassembled so that the damaged straight pipes can be replaced and then assembled together.
[0015] In the utility model, the described assembled cement-based grouting filling tube places two straight tubes in the placement grooves opened by the two support plates, and pushes the latch forward so that the latch is inserted into the through hole and the connecting groove. At this time, the locking rod is compressed back into the cavity and squeezes the squeezing spring. When it is fully inserted, the abutment plate abuts against the rear side of the support plate, and the locking rod is aligned with the locking groove. Under the elastic force of the squeezing spring, the locking rod moves down and is clamped in the locking groove. Under the limiting fixation of the latch, the two straight tubes can be effectively fixed to avoid the filling tube from moving up and down during testing and affecting the accuracy of the test. When not in use, the ball and the pull rod can be pulled upward, and the pull rod drives the lifting plate and the locking rod to move up and disengage from the locking groove, so that the latch is not fixed. At this time, the latch can be removed, and then the filling tube can be taken out from the placement groove.
[0016] The utility model has a reasonable structural design, and can conveniently, quickly and efficiently assemble or disassemble two straight tubes into a filling tube. When one straight tube is damaged, the two straight tubes can be disassembled so that the damaged straight tube can be replaced and then assembled together, thereby avoiding direct discarding and causing waste. The filling tube can also be effectively limited and fixed, so that the filling tube will not move up and down and shake to affect the accuracy of the test. BRIEF DESCRIPTION OF THE DRAWINGS

When assembling the filling tube, the two flanges 7 are aligned, and then the plug plate 10 and the limit plate 8 are squeezed to the left so that the plug plate 10 is inserted into the socket 9 At this time, the card plate 11 is automatically compressed back into the slide groove 13 and squeezes the return spring 14, so as not to hinder the plug plate 10 from being fully inserted into the two sockets 9. When the limit plate 8 abuts against the flange 7 on the rear side, the card plate 11 is not compressed at this time. Under the elastic force of the return spring 14, the two card plates 11 extend out and clamp on one side of the flange 7 on the left side, so that the two flanges 7 can be connected together, and the two straight tubes 3 can be connected and assembled into a filling tube. When disassembling, the two card plates 11 are pressed to retract the two card plates 11 into the slide groove 13 without fixing the plug plate 10. At this time, the plug plate 10 can be pulled out without fixing the two flanges 7, and the two straight tubes 3 can be disassembled so that the damaged straight tube 3 can be replaced and then assembled together.
