Description

Technical Field

[0001] The utility model relates to the technical field of concrete anti-seepage testing, and more specifically, to an automatic concrete pressurization anti-seepage tester. Background Art

[0002] The impermeability of porous bodies with different pore sizes is determined by the pressure difference in the surrounding medium, which will cause the medium to migrate in accordance with fluid mechanics, i.e., permeability. The impermeability of concrete is a basic performance of concrete and an important characteristic of its durability. Therefore, in construction projects, it is often necessary to test the impermeability of concrete materials. The relevant existing impermeability tester includes a body, which is provided with several experimental seats for placing samples. The experimental seats are detachably connected to test molds, which are used to install the samples. The test personnel screw the test molds onto the body, so that the samples are set on the test seats. The user can use the body to test multiple samples at the same time to preliminarily obtain the impermeability of the samples.

[0003] The existing patent number is CN213482009U, a high-efficiency automatic pressurized concrete impermeability tester, which relates to the technical field of concrete impermeability testers. The tester comprises a body, on which are provided several test blocks, a sliding frame slidably provided on the body, the sliding frame being arranged above the test blocks, and a clamping mechanism for clamping the sample provided on the sliding frame. This application facilitates the user to quickly move the sample and place the sample on the test block. However, the model and shape of the test block provided within the test block cannot be changed, and only concrete blocks of the same model and shape can be tested. This leads to low test adaptability and a large limitation on the testable models. Utility Model Content

There are two groups of material positioning assemblies 22, and the other group of material positioning assemblies 22 are installed on the inner and outer walls of the upper end of the pressurized anti-seepage instrument body 1.

[0022] The material positioning assembly 22 includes: a positioning support seat 226, an upper fixed rod 225, a lower fixed rod 222, a cross positioning groove 223, a cross positioning block 224, an assembly sleeve 227 and a second electric hydraulic cylinder 221, the output end of the second electric hydraulic cylinder 221 is mounted on the upper end of the lower fixed rod 222, the cross positioning groove 223 is opened inside the upper end of the lower fixed rod 222, the lower end of the cross positioning block 224 is detachably mounted inside the cross positioning groove 223, the upper end of the cross positioning block 224 is mounted on the lower end of the upper fixed rod 225, the upper end of the upper fixed rod 225 is mounted on the lower end of the positioning support seat 226, the upper fixed rod 225 and the lower fixed rod 221 are mounted on the lower end of the positioning support seat 226, and the upper fixed rod 225 and the lower fixed rod 221 are mounted on the lower end of the positioning support seat 226. 22 outer walls are provided with threaded assembly protrusions, and threaded assembly grooves are provided inside the assembly sleeve 227. The assembly sleeve 227 can be detachably installed on the outer walls of the upper fixed rod 225 and the lower fixed rod 222.

[0023] The specific implementation method is as follows: when using the present invention, it is necessary to start the first electric hydraulic cylinder 211 first. After the first electric hydraulic cylinder 211 is started, it drives the processing storage frame 215, the sealing cover 213 and the sliding support foot 214 installed at the output end to move out. After the processing storage frame 215 is moved out, the staff can place the concrete blocks that need to be tested on the upper ends of the multiple groups of positioning support seats 226 in sequence. When the upper ends of the positioning support seats 226 are placed, the second electric hydraulic cylinder 221 installed at the lower end can be started. After the second electric hydraulic cylinder 221 is started, it drives the positioning support seat 226 installed at the output end to move upward. After the positioning support seat 226 is moved out, it is convenient for the staff to observe and place the concrete blocks.

Positioning work on both the upper and lower ends of the concrete can effectively avoid the problem of displacement during the test. When the pressurized anti-seepage instrument body 1 needs to perform fixed testing on concrete blocks of different shapes, the assembly sleeve 227 can be taken out by rotating the assembly sleeve 227. After the assembly sleeve 227 is taken out, the upper fixing rod 225 and the lower fixing rod 222 can be separated. After the upper fixing rod 225 and the lower fixing rod 222 are separated, the shape and model size of the positioning support seat 226 installed on the upper end can be replaced. The model of the positioning support seat 226 can be replaced, which solves the positioning problem of testing concrete of different models and shapes, and further improves the stability and adaptability of the entire device.

[0024] The working principle of the present invention is as follows: when using the present invention, it is necessary to start the first electric hydraulic cylinder 211 first. After the first electric hydraulic cylinder 211 is started, it drives the processing storage frame 215, the sealing cover 213 and the sliding support foot 214 installed at the output end to move out. After the processing storage frame 215 is moved out, the staff can place the concrete blocks that need to be tested on the upper ends of the multiple groups of positioning support seats 226 in sequence. When the upper ends of the positioning support seats 226 are placed, the second electric hydraulic cylinder 221 installed at the lower end can be started. After the second electric hydraulic cylinder 221 is started, it drives the positioning support seat 226 installed at the output end to move upward. After the positioning support seat 226 is moved out, it is convenient for the staff to observe and place the work. When the concrete blocks on the upper ends of the multiple groups of positioning support seats 226 are placed, they are driven by the first electric hydraulic cylinder 211 to return to the inside of the pressurized anti-seepage instrument body 1, and the pressurized anti-seepage instrument body 1 is closed. The sealed control cabinet door 23 set at the front end is used for subsequent testing work. When the positioning support seat 226 enters the interior of the pressurized anti-seepage instrument body 1, the positioning support seat 226 set at the upper end of the pressurized anti-seepage instrument body 1 moves downward, which can perform positioning and support work on the upper end of the lower concrete block. After the upper and lower ends of the concrete block are supported, the pressurized anti-seepage instrument body 1 can be used to cooperate with the pressurized anti-seepage instrument body 1 to perform subsequent penetration testing. Positioning work is performed on both the upper and lower ends of the concrete to effectively avoid the problem of displacement during the test. When the pressurized anti-seepage instrument body 1 needs to perform fixed testing on concrete blocks of different shapes, the assembly sleeve 227 can be taken out by rotating the assembly sleeve 227. After the assembly sleeve 227 is taken out, the upper fixing rod 225 and the lower fixing rod 222 can be separated. After the upper fixing rod 225 and the lower fixing rod 222 are separated, the shape and model size of the positioning support seat 226 installed at the upper end can be replaced.
