Description

Technical Field

[0001] This utility model belongs to the field of concrete testing technology, and more specifically, it relates to an automatic pressurization device for testing the durability of concrete against chloride ion penetration. Background Technology

[0002] Chloride ion penetration resistance durability testing is a core durability test for evaluating the ability of cementitious materials such as concrete to resist chloride ion intrusion. It is mainly used to determine whether materials can slow down chloride ion-induced steel corrosion and structural performance deterioration during long-term service (such as marine, saline soil, and de-icing salt environments), ultimately extending the service life of the project. The electrical flux method is a classic test method for rapidly assessing the chloride ion penetration resistance of concrete. It applies a stable DC voltage to "push" charged chloride ions through the concrete specimen. By measuring the amount of electrical charge (unit: coulomb) that passes through in 6 hours, the compactness and durability of the concrete are indirectly evaluated. The pressurization device is the core key equipment for realizing the automation, standardization, accuracy, and efficiency of the electrical flux method. It generally consists of a shell, a DC power supply module, a measurement and data acquisition module, and a circuit module.

[0003] Existing application number: CN202220313877.6, this utility model provides a concrete chloride ion permeation tester, which consists of an electrical flux measuring unit and a test unit. A fixing block and an electric push rod fixed to the fixing block are fixed on the right side of the upper surface of the test unit's base plate. The electric push rod faces left and has a movable plate fixed to its end. The fixing plate is fixed to the left end of the upper surface of the base plate, and test tanks are fixedly installed on opposite sides of both the fixing plate and the movable plate. A placement platform is fixed slightly to the left of the center of the upper surface of the base plate. The electrical flux measuring unit is electrically connected to the two test tanks via wires. Before testing, the concrete component is placed on the placement platform, and then the electric push rod is activated to tightly clamp the concrete component in the two test tanks. Reagent is then poured into the test tanks, and the electrical flux measuring unit is activated to perform the concrete chloride ion permeation test. This instrument provides a quick and convenient process for fixing and separating the concrete component. The pushing force provided by the electric push rod is stable, and the solution in the test tanks is less prone to leakage, ensuring the accuracy of the test results.

[0004] Based on the above, after the automatic pressurization device for chloride ion penetration durability testing is used, the multiple electrode wires used in the test are often scattered and tangled after being unplugged from the wire interface due to the lack of a dedicated wire storage structure. This not only increases the time spent organizing the wires before the next experiment, but also easily causes damage to the wire insulation layer due to tangling and pulling, posing a risk of leakage and increasing the cost of equipment maintenance and replacement. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic pressurization device for chloride ion penetration durability testing. This solves the problem that in existing automatic pressurization devices for chloride ion penetration durability testing, after use, the multiple electrode wires used in the test are often scattered and tangled after being unplugged from the wire interface due to the lack of a dedicated wire storage structure. This not only increases the time spent organizing the wires before the next experiment but also easily damages the wire insulation layer due to tangling and pulling, posing a potential safety hazard of electrical leakage and increasing equipment maintenance and replacement costs.

[0006] The purpose and effectiveness of this utility model's automatic pressurization device for chloride ion penetration durability testing are achieved through the following specific technical means: An automatic pressurization device for chloride ion penetration resistance durability testing includes a pressurization device body, wire interfaces, support blocks, a storage box, an operating handwheel, a connecting shaft, a winding and storage assembly, and a separation and assembly assembly. Multiple wire interfaces are provided, each located at the front of the pressurization device body. Two support blocks are provided, each fixedly connected to the top of the pressurization device body. The storage box is fixedly connected to the top of the pressurization device body. The operating handwheel is rotatably connected to the left side of the storage box. The connecting shaft is rotatably connected inside the storage box, and is coaxially fixedly connected to the operating handwheel. The winding and storage assembly is located inside and at the front of the storage box. Two sets of separation and assembly assemblies are provided, each located inside the storage box.

[0007] Furthermore, the winding and storage assembly includes: a guide shaft, a guide roller, and a limiting slot; the left and right ends of the guide shaft are rotatably connected to the inside of the support block; the guide roller is coaxially fixedly connected to the outside of the guide shaft; the limiting slot has an "L" shaped structure and is opened inside the front of the storage box.

[0008] Furthermore, the winding and storage assembly also includes: a winding roller and interface fasteners; the winding roller is coaxially and fixedly connected to the outside of the connecting shaft; two sets of interface fasteners are provided, each set of interface fasteners is provided with multiple pieces, and the two sets of interface fasteners are respectively fixedly connected to the outside of the winding roller.

[0009] Furthermore, the winding and storage assembly also includes: a transmission box, a limiting ratchet, a limiting pawl, and a return spring; the transmission box is fixedly connected to the left side of the storage box; the limiting ratchet is coaxially fixedly connected to the outside of the connecting shaft; the limiting pawl is rotatably connected inside the transmission box, and the limiting pawl meshes with the limiting ratchet; the right end of the return spring is fixedly connected to the top left side of the limiting pawl, and the left end of the return spring is fixedly connected to the inside of the transmission box.

[0010] Furthermore, the separate assembly component includes: a fixing box, a sliding plate, an operation key, and a positioning key; the fixing box is fixedly connected to the lower part of the interface fixing component; the sliding plate is slidably connected inside the fixing box; the operation key is fixedly connected to the lower part of the sliding plate; and the positioning key is fixedly connected to the lower part of the sliding plate.

[0011] Furthermore, the separate assembly also includes: a positioning spring, a mating component, and a mating groove; the bottom of the positioning spring is fixedly connected to the top of the sliding plate, and the top of the positioning spring is fixedly connected to the inside of the fixing box; the mating component is fixedly connected to the outside of the take-up roller; and the mating groove is formed inside the mating component.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, with the winding and storage component, there is no need to disconnect the wire from the main wire interface of the pressure device. Simply fix the other end of the wire to the interface fixing piece on the outside of the winding roller, and turn the operating handwheel to drive the winding roller to wind the wire. At the same time, the ratchet and pawl structure prevents the wire from reversing and scattering after winding, thus taking into account both wire protection and convenient wire storage.

[0013] Secondly, in multi-wire storage scenarios, pressing the operation button can move the sliding plate and positioning button upwards, allowing the interface fixing piece to be removed from the take-up roller. After batch completion of the insertion and fixing of the wire ends to the interface fixing piece, the interface fixing piece can be reconnected to the take-up roller. This not only continues the advantages of wire storage but also improves the operational flexibility when storing multiple wires.

[0014] This invention eliminates the need to disconnect the wire from the main wire interface of the pressure device. The other end of the wire is fixed to the interface fixing piece on the outside of the winding roller, and the wire can be wound by rotating the operating handwheel. This design balances convenient storage with wire protection. The interface fixing piece can be easily removed individually, facilitating the storage of multiple wires. This design not only reduces the time cost of wire preparation before and after testing and minimizes wire loss due to tangling and scratching, but also ensures the stability of the wire connection, providing reliable support for the efficient advancement of chloride ion penetration durability testing and the accuracy of test data.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides an automatic pressurization device for testing the durability of chloride ion penetration resistance, including a pressurization device body 1, wire interface 101, support block 102, storage box 2, operating handwheel 3, connecting shaft 6, and winding and storage assembly; multiple wire interfaces 101 are provided, and the multiple wire interfaces 101 are respectively provided in front of the pressurization device body 1; two support blocks 102 are provided, and the two support blocks 102 are respectively fixedly connected to the upper part of the pressurization device body 1; the storage box 2 is fixedly connected to the upper part of the pressurization device body 1; the operating handwheel 3 is rotatably connected to the left side of the storage box 2; the connecting shaft 6 is rotatably connected inside the storage box 2, and the connecting shaft 6 is coaxially fixedly connected to the operating handwheel 3; the winding and storage assembly is arranged inside and in front of the storage box 2.

[0023] The winding and storage assembly includes: a guide shaft 4, a guide roller 401, and a limiting slot 5; the left and right ends of the guide shaft 4 are rotatably connected to the inside of the support block 102; the guide roller 401 is coaxially fixedly connected to the outside of the guide shaft 4; the limiting slot 5 has an "L" shaped structure and is opened in front of the storage box 2.

[0024] The winding and storage assembly also includes: a winding roller 601 and an interface fixing member 7; the winding roller 601 is coaxially fixedly connected to the outside of the connecting shaft 6; two sets of interface fixing members 7 are provided, each set of interface fixing members 7 is provided with multiple pieces, and the two sets of interface fixing members 7 are respectively fixedly connected to the outside of the winding roller 601.

[0025] The winding and storage assembly also includes: a transmission box 201, a limiting ratchet 602, a limiting pawl 8, and a return spring 801; the transmission box 201 is fixedly connected to the left side of the storage box 2; the limiting ratchet 602 is coaxially fixedly connected to the outside of the connecting shaft 6; the limiting pawl 8 is rotatably connected inside the transmission box 201, and the limiting pawl 8 meshes with the limiting ratchet 602; the right end of the return spring 801 is fixedly connected to the top left side of the limiting pawl 8, and the left end of the return spring 801 is fixedly connected to the inside of the transmission box 201.

[0026] The specific usage and function of this embodiment: After the wire is used, one end inserted into the wire interface 101 does not need to be pulled out. The wire enters through the opening at the top right of the limiting slot 5 and is confined inside by the elongated opening at the bottom of the limiting slot 5. Then, the other end of the wire is inserted into the interface fixing member 7 on the outside of the take-up roller 601. Afterward, the operating handwheel 3 is turned clockwise, which drives the connecting shaft 6 and the take-up roller 601 to rotate together, thereby winding the wire around the outside of the take-up roller 601. The wire contacts the top of the wire roller 401, ensuring that the wire does not rub against or wear against the top edge of the pressure device body 1. Under the action of the ratchet-pawl transmission mechanism formed by the engagement of the limiting ratchet 602 and the limiting pawl 8, the connecting shaft 6 can only rotate in one direction, so that the wire will not easily reverse and fall off after being wound on the outside of the take-up roller 601. When using it again, just pull the top of the limiting pawl 8 backward to disengage the limiting pawl 8 from the limiting ratchet 602, and then pull the wire exposed in front of the storage box 2 to drive the take-up roller 601 to rotate counterclockwise, so that the wire can be unwound for reuse. After that, release the top of the limiting pawl 8, and under the rebound action of the return spring 801, the limiting pawl 8 and the limiting ratchet 602 will re-engage for the next use. Example 2

[0027] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes two sets of detachable assembly components, which are respectively installed inside the storage box 2.

[0028] The separate assembly components include: a fixing box 9, a sliding plate 10, an operation key 1001, and a positioning key 1002; the fixing box 9 is fixedly connected to the bottom of the interface fixing component 7; the sliding plate 10 is slidably connected inside the fixing box 9; the operation key 1001 is fixedly connected to the bottom of the sliding plate 10; and the positioning key 1002 is fixedly connected to the bottom of the sliding plate 10.

[0030] The specific usage and function of this embodiment: When there are many wires to be stored, press the operation key 1001 upwards to move the sliding plate 10 and the positioning key 1002 upwards. The positioning key 1002 will disengage from the mating groove 1101. Then, move the interface fixing piece 7 forward to remove it from the outside of the winding roller 601. This makes it easy to take out a set of interface fixing pieces 7 from the storage box 2. After inserting and fixing the end of the wire into the interface fixing piece 7, pass the wire through the limiting groove 5, press the operation key 1001 upwards again, and then insert the fixing box 9 into the mating piece 11. Release the operation key 1001. Under the rebound action of the positioning spring 1003, the positioning key 1002 will be inserted into the mating groove 1101, so that the interface fixing piece 7 is fixed on the outside of the winding roller 601. Then, turn the operation handwheel 3 clockwise again to wind up the wire.
