Abstract

This utility model relates to the technical field of concrete permeability testing devices, and discloses a high-efficiency permeability testing device for recycled concrete, including a permeability tester, a handrail, a mold base, a controller, and a handle. A rotating rod is connected to the handle, and an insertion port is opened on the side edge of the rotating rod. A linkage frame is slidably connected to the permeability tester above the rotating rod. The linkage frame is arranged along the length of the permeability tester. The permeability tester is provided with an insertion rod, which is inserted into the insertion port of the rotating rod. One end of the linkage frame has a protrusion. After the sample is placed in the mold base of the device, the water pressure is adjusted. After adjustment, the rotating plate is swung, and the rotating plate will not support the linkage frame.

Description

Technical Field

[0001] This utility model relates to the technical field of concrete impermeability testing devices, and in particular to a high-efficiency impermeability testing device for recycled concrete. Background Technology

[0002] Concrete is an important building material, and its performance directly affects the service life and safety of buildings. Among them, the impermeability of concrete is a very important indicator, which plays a crucial role in ensuring the waterproofness and durability of buildings. Therefore, the testing of the impermeability of concrete is an essential part of construction engineering. Concrete impermeability testing equipment is mainly used for testing the impermeability of concrete and determining its impermeability grade. Impermeability refers to the ability of materials used in a structure to resist the penetration of water and other liquid media under pressure. The testing of concrete impermeability usually uses an impermeability testing device, and the sample is placed in the mold of the testing device for testing.

[0003] However, existing anti-permeability testing devices have the following drawbacks:

[0004] When using a seepage detection device, the water pressure needs to be adjusted by manually controlling the valves. However, the valves of the seepage detection device are exposed and multiple valves are close together. When adjusting a single valve, it is easy to accidentally touch another valve, which will cause changes in water pressure and affect the detection data.

[0005] Therefore, this utility model provides a high-efficiency permeability testing device for recycled concrete. Utility Model Content

[0006] Technical problems to be solved

[0007] The problem solved by this utility model is to provide a highly practical and efficient anti-seepage detection device for recycled concrete, which solves the problem mentioned in the background art that the handle is easily accidentally touched, leading to changes in water pressure.

[0008] Technical solution

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency permeability testing device for recycled concrete, comprising a permeability testing instrument, a handrail, a mold base, a controller, and a handle. A rotating rod is connected to the handle, and an insertion port is provided on the side edge of the rotating rod. A linkage frame is slidably connected to the permeability testing instrument above the rotating rod. The linkage frame is arranged along the length of the permeability testing instrument. An insertion rod is provided on the permeability testing instrument, and the insertion rod is inserted into the insertion port of the rotating rod. A protrusion is attached to one end of the linkage frame.

[0010] Optionally, the permeability testing instrument is equipped with a guide seat, which is vertically arranged on the permeability testing instrument and connected to the linkage frame.

[0011] Optionally, a guide opening is provided at the position corresponding to the guide seat of the linkage frame, and the guide seat is slidably connected in the guide opening of the linkage frame.

[0012] Optionally, a connecting frame is fixedly connected to the linkage frame, and a first vertical frame and a second vertical frame are respectively connected to both ends of the connecting frame.

[0013] Optionally, the first and second vertical frames have the same structure, both of which are L-shaped, and the insertion rod is located on the connecting frame.

[0014] Optionally, the protrusion is disposed on the side wall of the rotating plate, the rotating plate is circular in shape, and a movable rod is disposed at the central axis of the rotating plate, the movable rod being rotatably connected to the permeability tester.

[0015] Beneficial effects

[0016] This utility model provides a high-efficiency permeability testing device for recycled concrete, which has the following beneficial effects:

[0017] This high-efficiency permeability testing device for recycled concrete involves installing a guide seat on the permeability testing instrument. A linkage frame can be mounted on the guide seat, allowing the linkage frame to move up and down within the guide seat. A connecting frame with an insertion rod is mounted on the linkage frame, moving up and down with the linkage frame. The insertion rod corresponds to a rotating rod on the handle, allowing it to be inserted into the insertion slot of the rotating rod. As the handle is rotated for adjustment, the position of the insertion slot on the rotating rod changes accordingly. Once the insertion rod is inserted, the handle remains stably adjusted, preventing rotation due to external force. For further adjustment, the linkage frame is pushed upwards, and then the rotating plate is rotated until its protrusion aligns with the linkage frame. The rotating plate then supports the linkage frame, allowing the insertion rod to be pulled out of the insertion slot of the rotating rod, thus enabling handle adjustment. After adjustment, the linkage frame is lowered, and the handle is again locked in place, preventing rotation due to external force and ensuring stable water pressure, thus guaranteeing accurate test data.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a high-efficiency permeability testing device for recycled concrete, including a permeability tester 1, a handrail 3, a mold base 2, a controller 17, and a handle 5. A rotating rod 6 is connected to the handle 5, and an insertion port 7 is opened on the side edge of the rotating rod 6. A linkage frame 4 is slidably connected to the permeability tester 1 above the rotating rod 6. The linkage frame 4 is arranged along the length of the permeability tester 1. An insertion rod 11 is provided on the permeability tester 1, and the insertion rod 11 is inserted into the insertion port 7 of the rotating rod 6. A protrusion 13 is attached to one end of the linkage frame 4. After the sample is placed in the mold base 2 of the device, the water pressure is adjusted. After the adjustment is completed, the rotating plate 14 is swung. The rotating plate 14 will not support the linkage frame 4, and the linkage frame 4 can drive the insertion rod 11 to be inserted into the insertion port 7 of the rotating rod 6. The rotating rod 6 is restricted, and the handle 5 will not be rotated by external force, thereby ensuring that the water pressure does not change and ensuring the accuracy of the test data.

[0025] The permeability tester 1 is equipped with a guide seat 10, which is vertically arranged on the permeability tester 1. The guide seat 10 is connected to the linkage frame 4. The linkage frame 4 can be restricted by the guide seat 10, and the linkage frame 4 can move up and down at the position of the guide seat 10.

[0026] A guide opening 16 is provided at the position corresponding to the guide seat 10 of the linkage frame 4. The guide seat 10 is slidably connected in the guide opening 16 of the linkage frame 4. By opening the guide opening 16, the guide seat 10 can be connected in the guide opening 16. When the guide seat 10 and the guide opening 16 are connected, the friction between them will be small, which makes it easier to pull the linkage frame 4.

[0027] A connecting frame 9 is fixedly connected to the linkage frame 4. The first vertical frame 8 and the second vertical frame 12 are respectively connected to the two ends of the connecting frame 9. The plug rod 11 can be fixed through the connecting frame 9. When the linkage frame 4 moves up and down, the plug rod 11 can move up and down, and the plug rod 11 can be inserted into or pulled out of the plug 7.

[0028] The first vertical frame 8 and the second vertical frame 12 have the same structure. Both the first vertical frame 8 and the second vertical frame 12 are L-shaped. The insertion rod 11 is located on the connecting frame 9. The first vertical frame 8 and the second vertical frame 12 can be located on both sides of the rotating rod 6, thereby restricting the linkage frame 4. The linkage frame 4 will not be displaced, which will prevent the insertion rod 11 from being connected to the insertion port 7.

[0029] The protruding head 13 is set on the side wall of the rotating plate 14. The rotating plate 14 is circular in shape. A movable rod 15 is set at the central axis of the rotating plate 14. The movable rod 15 is rotatably connected to the impermeability tester 1. The rotating plate 14 can support the linkage frame 4 through the protruding head 13.

[0030] In this invention, the working steps of the device are as follows:

[0031] First step: By installing a guide seat 10 on the permeability tester 1, a linkage frame 4 can be installed on the guide seat 10. The linkage frame 4 can move up and down at the guide seat 10. A connecting frame 9 is installed on the linkage frame 4, and an insertion rod 11 is set on the connecting frame 9. The insertion rod 11 can move up and down with the linkage frame 4. The insertion rod 11 corresponds to the rotating rod 6 on the handle 5. The insertion rod 11 can be inserted into the insertion port 7 of the rotating rod 6. When the handle 5 is rotated for adjustment, the position of the insertion port 7 on the rotating rod 6 will change accordingly.

[0032] Step 2: After the insertion rod 11 is inserted into the socket 7, the handle 5 can be stably kept in the adjustment state and will not be rotated by external force. When it is necessary to adjust again, push the linkage frame 4 up and then rotate the rotating plate 14. After the protrusion 13 of the rotating plate 14 is rotated to the position of the linkage frame 4, the rotating plate 14 can support the linkage frame 4 as a whole. The insertion rod 11 will be pulled out from the socket 7 of the rotating rod 6, so that the handle 5 can be adjusted. After the adjustment is completed, put down the linkage frame 4, and the handle 5 can be limited again, so it will not be rotated by external force, ensuring that the water pressure does not change and ensuring the accuracy of the test data.

However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming.

The machinery, parts and equipment adopt conventional models in the existing technology, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.
