Detailed Implementation
[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0030] See attached document Figure 1 - Appendix Figure 7 The present invention provides a concrete permeability meter sealing cylinder lifting device with locking function, comprising:
[0031] The frame 1 has an electric push rod 2 fixedly embedded in the top of the frame 1. A movable plate 3 is fixedly sleeved on the top of the electric push rod 2. Multiple circumferentially distributed pads 4 are fixedly connected to the top of the frame 1. Each pad 4 has a through hole. Each pad 4 has a concrete block body 5 on its top. Each concrete block body 5 is sleeved with an anti-seepage detection component.
[0032] The guide post 6 is configured as a plurality of guide posts 6 evenly distributed in a circumferential shape. The plurality of guide posts 6 are fixedly embedded on the moving plate 3. The sleeves 7 are slidably sleeved on the outside of the plurality of guide posts 6. The sleeves 7 are fixedly embedded on the top of the frame 1. Locking components are provided between the plurality of guide posts 6 and the plurality of sleeves 7 respectively.
[0033] The locking assembly includes a through hole 8, which is opened outside the guide post 6. Through holes 9 are opened on both sides of the sleeve 7. A cylinder 10 is fixedly connected to the inner wall of the top of the frame 1. A moving block 11 is fixedly connected to one end of the cylinder 10. A pin 12 is fixedly connected to one side of the moving block 11. The pin 12 passes through the through hole 8 and the two through holes 9 and slides in contact with them.
[0034] Multiple pads 4 are all made of rubber material;
[0035] In this embodiment, multiple guide posts 6 are designed on the movable plate 3, and a sleeve 7 is fitted on each of the multiple guide posts 6. In addition, a locking assembly is designed between the sleeve 7 and the guide post 6. When the sealing cylinder 15 is fitted on the concrete block body 5, the cylinder 10 in the locking assembly is controlled to work so that the pin 12 passes through the first through hole 8 and the two second through holes 9. This can prevent the guide post 6 from sliding freely between the sleeve 7, thus restricting the movable plate 3 and locking the sealing cylinder 15.
[0036] In order to achieve the purpose of pulling upward, the device adopts the following technical solution: a limiting rod 13 is fixedly connected to the inner wall of the top of the frame 1. The limiting rod 13 passes through the moving block 11 and slides in contact with it. The cross section of the limiting rod 13 is set as T-shaped. The T-shaped limiting rod 13 can pull the moving block 11 and the pin 12 upward.
[0037] In order to achieve the positioning purpose, the device adopts the following technical solution: a positioning block 14 is fixedly connected to one side of the moving block 11. The positioning block 14 is in contact with the sleeve 7. When the moving block 11 moves, the positioning block 14 will move accordingly. When the positioning block 14 is in contact with the sleeve 7, it means that the pin 12 has passed through the through hole 8 and the two through holes 9.
[0038] To achieve the purpose of seepage detection, the device adopts the following technical solution: The seepage detection component includes a sealing cylinder 15, which is fixedly embedded on the moving plate 3 and the bottom end of the sealing cylinder 15 is in contact with the pad plate 4. The sealing cylinder 15 is sleeved on the outside of the concrete block body 5. A rubber sleeve 16 is fixedly connected to the inner wall of the sealing cylinder 15 and wraps around the outside of the concrete block body 5. A housing 17 is fixedly connected to the bottom end of the electric push rod 2. Four connecting rods 18 are fixedly connected between the housing 17 and the top inner wall of the frame 1. A bidirectional water pump 19 is fixedly connected to the bottom inner wall of the frame 1. A pipe 20 is fixedly connected between the bidirectional water pump 19 and the housing 17. A hose 21 is fixedly connected to the inlet of the bidirectional water pump 19. Multiple pipes 22 are fixedly embedded in the top of the housing 17. The top ends of the multiple pipes 22 extend into the interior of multiple through holes. The multiple pipes 22 all penetrate the top of the frame 1 and are fixedly connected to it.
[0039] The usage process of this utility model is as follows: When it is necessary to conduct a permeability test on a concrete block, a concrete block body 5 is placed on each pad plate 4. Then, the electric push rod 2 is controlled to move the moving plate 3 and multiple sealing cylinders 15 downwards until the sealing cylinders 15 contact the pad plate 4. The downward movement of the sealing cylinders 15 can cover the outside of the concrete block body 5. At the same time, the rubber sleeve 16 in the sealing cylinder 15 can be fitted onto the concrete block body 5. Moreover, the rubber sleeve 16 will be squeezed and undergo elastic deformation, so that the rubber sleeve 16 can be in close contact with the concrete block body 5.
[0040] When the electric push rod 2 moves the moving plate 3 and the sealing cylinder 15 downward, it can also move multiple guide posts 6 downward. When the central axis of the through hole 8 on the guide post 6 is aligned with the central axis of the two through holes 9 on the sleeve 7, the sealing cylinder 15 can also squeeze the pad 4, which can cause the pad 4 to undergo elastic deformation. Then, multiple cylinders 10 are controlled to work to move multiple moving blocks 11 outward, which can cause multiple pins 12 to move outward. Then the pins 12 can pass through the through hole 8 and the two through holes 9, which can prevent the guide post 6 from sliding freely between the sleeve 7. This can restrict the moving plate 3 and lock the sealing cylinder 15 to prevent its displacement.
[0041] Next, connect the end of the hose 21 to the water source. Then, under the action of the hose 21, pipe 1 20, shell 17 and multiple pipes 22, control the bidirectional water pump 19 to deliver water to multiple sealing cylinders 15. Since the rubber sleeve 16 is in close contact with the concrete block body 5, the sealing cylinder 15 has a squeezing effect on the pad 4. This can prevent water from leaking between the rubber sleeve 16 and the concrete block body 5 and between the sealing cylinder 15 and the pad 4 when delivering water. Moreover, the locking component can lock the sealing cylinder 15 so that it cannot move. This can ensure the accuracy of the test results during the seepage resistance test. Even if the water pressure increases, the sealing cylinder 15 will not move and there will be no inaccurate test results.
[0042] During the test, you only need to observe whether there is a watermark on the top of the concrete block body 5. If there is no watermark, it indicates that the concrete block body 5 has a good anti-seepage effect, and vice versa.
[0043] After the seepage prevention is completed, the reverse steps control the above components to release the lock and move the sealing cylinder 15 upward, and then the tested concrete block body 5 can be removed.
[0044] In this application, the model and specifications of the electric push rod 2, cylinder 10, and bidirectional water pump 19 need to be selected and determined according to the actual specifications of the entire device. Moreover, the above-mentioned components are very mature products in the prior art, so the specific model and specifications will not be described in detail. In addition, the electrical control structure, pneumatic control structure and control principle of the above-mentioned components are clear to those skilled in the art, so the control method and circuit connection will not be described in detail.
[0045] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
