The invention relates to a grout stopping machine tool performance testing device, aiming at overcoming the defect that the existing testing device can not monitor the stress situation of a fixing device and a sealing device of a grout stopping machine tool simultaneously when testing the sealing performance thereof. The testing device is characterized in that the bottom part of a bracket is articulated with a lower part steel tube mould connected with an upper part steel tube mould; a force measuring sensor II is arranged at the joint part between the upper part steel tube mould and the lowerpart steel tube mould, cavities of the upper part steel tube mould and the lower part steel tube mould are provided with the grout stopping machine tool to be tested, the upper end of the grout stopping machine tool to be tested is provided with a force measuring sensor I and is connected with a piston of a hydraulic cylinder, and the sealing device of the grout stopping machine tool to be testedis provided with a displacement sensor; and the tube wall of the lower part steel tube mould is provided with a force measuring sensor III and a data acquisition device connected with a computer. Thetesting device can monitor and record the friction force between the fixing device and a hole wall as well as the stress situation between the sealing device and the hole wall when testing the sealing performance of the grout stopping machine tool.
Description
technical field [0001] The invention relates to a device capable of monitoring the force condition of the slurry stopper while checking the sealing performance of the stopper, in particular a device for testing the performance of the stopper. Background technique [0002] At present, the anti-slurry equipment used in engineering generally includes a positioning device and a sealing device. When working, it is positioned by the positioning device. Under the action of the axial force, the sealing device is compressed to expand radially to achieve sealing and play a role in preventing slurry and water. role. In actual working conditions, only the fixing device and sealing device of the grout stopper are in contact with the hole wall, and the sum of the friction between the two and the hole wall balances the setting force and the force of the sealing grout, so the pressure resistance of the grout stopper depends on The friction force between the fixing device and the sealing de...
