Description

Technical Field

[0001] The utility model relates to the technical field of novel concrete testing, in particular to novel concrete testing equipment. Background Art

[0002] New concrete refers to a concrete material that is improved by improving the formula of traditional concrete materials, adding new ingredients or adopting new production processes to provide higher performance, more environmentally friendly or achieve specific functions. After the production of new concrete is completed, a series of tests are required to evaluate the performance and quality of the concrete. Concrete tests include compressive strength, flexural strength, density tests, etc.

[0003] The Chinese patent "A concrete pressure testing device" authorization announcement number "CN216978659U" uses a lifting plate and a sponge pad to limit the front and rear sides of the concrete block, thereby preventing the concrete block from sliding during the pressure test.

[0004] However, when the pressure plate is pressing down on the concrete block, the downward pressure will be transmitted to the lifting plate, causing the lifting plate to deform, which will further interfere with the stress state of the concrete block, resulting in deviations in the concrete pressure test results.

[0005] Therefore, a new concrete testing equipment is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a novel concrete testing device in order to solve the above problems, thereby improving the problem that the lifting plate limits the lifting of concrete, which easily affects the stress state of the concrete.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme. The novel concrete testing equipment comprises: a test box, the inner top wall of the test box is fixedly connected with a hydraulic cylinder, the bottom end of the hydraulic cylinder is fixedly connected with a pressure block, and the inner wall of the test box is provided with a limiting mechanism; wherein the limiting mechanism comprises a slide tube fixedly connected to both sides of the inner wall of the test box, the inner wall of the slide tube is slidably connected with a slide rod, one end of the slide rod is fixedly connected with a movable frame, the inner wall of the movable frame is slidably connected with a movable block, one end of the movable block is fixedly connected with a limiting block, and the inner wall of the test box is provided with a driving component.

[0008] Preferably, the driving assembly includes an air storage box fixedly connected to the bottom wall of the test box, the inner wall of the air storage box is slidably connected with an air pusher, the front end of the air pusher is fixedly connected to the surface of the pressure block, both sides of the air pusher are connected with air pipes, one end of the air pipe is connected to one end of the inner wall of the slide, one side of the inner wall of the movable frame is connected with an air outlet pipe, and the inner wall of the air outlet pipe is fixedly connected with a one-way air outlet valve. By using the pressure block, the air pusher and the air storage box, the gas in the air storage box is transported to the two slides respectively, so that the two limit blocks are close to each other and clamp the new concrete sample. Compared with the use of the lifting plate to limit the sample, this method ensures that the sample can be evenly stressed and ensures the accuracy of the new concrete pressure test. By using the air outlet pipe and the one-way air outlet valve, it is achieved that the limit block will not excessively clamp the sample, and thus will not affect the pressure resistance effect of the pressure block on the sample, thereby ensuring the effect of the sample pressure test.

[0009] Preferably, a first spring is fixedly connected to one side of the inner wall of the movable frame, and the other end of the first spring is fixedly connected to one side of the movable block. The first spring and the air outlet pipe are used to ensure that the limit block does not excessively clamp the sample, ensuring that the limit block can clamp the limit sample with balanced pressure.

[0010] Preferably, one side of the inner wall of the movable frame is connected to an air intake pipe, and the inner wall of the air intake pipe is fixedly connected to a one-way air intake valve. By using the first spring, the air intake pipe and the one-way air intake valve, external air can enter the movable frame through the air intake pipe, ensuring that a corresponding amount of air is stored in the movable frame.

[0011] Preferably, the inner walls of the air outlet pipe and the air inlet pipe are fixedly connected with a filter screen. The filter screen is used to prevent dust in the air from entering the movable frame through the air inlet pipe, thereby ensuring the cleanliness of the movable frame.

[0012] Preferably, one end of the slide rod is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to one end of the inner wall of the slide cylinder. The second spring enables the slide rod to move in the slide cylinder through the elastic force of the second spring, thereby allowing part of the gas in the slide cylinder to enter the gas storage box through the gas pipe.

[0013] Preferably, a concave hole is provided on one side of the limit block, and the shape of the concave hole is a "V" shape. By using the limit block and the concave hole, the limit block can clamp and position new concrete samples of other shapes.

[0014] Preferably, the upper end of the surface of the limit block forms an angle with the horizontal plane. By taking advantage of the inclined top of the limit block, the amount of new concrete sample debris adhering to the top of the limit block is reduced.

[0015] The beneficial effects of the utility model are:

[0016] By using the pressure block, the air pusher and the air storage box, the gas in the air storage box is transported to the two slides respectively, so that the two limit blocks are close to each other and clamp the new concrete sample. Compared with the use of the lifting plate to limit the sample, this method ensures that the sample can be evenly stressed and the accuracy of the new concrete pressure test is guaranteed. By using the air outlet pipe and the one-way air outlet valve, the limit block will not clamp the sample excessively, and will not affect the pressure resistance effect of the pressure block on the sample, thus ensuring the effect of the sample pressure test;

[0017] By utilizing the first spring, the air intake pipe and the one-way air intake valve, it is possible for outside air to enter the movable frame through the air intake pipe, thereby ensuring that a corresponding amount of air is present in the movable frame. By utilizing the second spring, the slide rod can move in the slide cylinder through the elastic force of the second spring, thereby allowing part of the gas in the slide cylinder to enter the air storage box through the air supply pipe.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4As shown, the novel concrete testing equipment comprises: a test box 1, a hydraulic cylinder 2 is fixedly connected to the inner top wall of the test box 1, a pressure block 3 is fixedly connected to the bottom end of the hydraulic cylinder 2, and a limiting mechanism 4 is arranged on the inner wall of the test box 1; wherein the limiting mechanism 4 comprises a slide cylinder 42 fixedly connected to both sides of the inner wall of the test box 1, a slide rod 43 is slidably connected to the inner wall of the slide cylinder 42, one end of the slide rod 43 is fixedly connected to a movable frame 44, a movable block 45 is slidably connected to the inner wall of the movable frame 44, one end of the movable block 45 is fixedly connected to the limiting block 41, and a driving assembly 46 is arranged on the inner wall of the test box 1, and the driving assembly 46 comprises an air storage box 461 fixedly connected to the inner bottom wall of the test box 1, and the air storage box 46 1 is slidably connected with an air push frame 462, the front end of the air push frame 462 is fixedly connected to the surface of the pressure block 3, both sides of the air push frame 462 are connected with air pipes 463, one end of the air pipe 463 is connected to one end of the inner wall of the slide 42, one side of the inner wall of the movable frame 44 is connected with an air outlet pipe 464, the inner wall of the air outlet pipe 464 is fixedly connected with a one-way air outlet valve 465, one side of the inner wall of the movable frame 44 is fixedly connected with a first spring 469, the other end of the first spring 469 is fixedly connected to one side of the movable block 45, one side of the limit block 41 is provided with a concave hole 4610, the shape of the concave hole 4610 is "V" shaped, and the upper end of the surface of the limit block 41 forms an angle with the horizontal plane.

[0025] When the new concrete is subjected to pressure test, the sample is placed in the test box 1, and the hydraulic cylinder 2 is started. The lower end of the hydraulic cylinder 2 drives the pressure block 3 to move downward, and the downward movement of the pressure block 3 drives the air push frame 462 to move downward in the air storage box 461, so that the gas in the air storage box 461 is respectively transported to the two slide cylinders 42 through the air delivery pipe 463. The excessive gas in the slide cylinder 42 drives the slide rod 43 to move, and the movement of the slide rod 43 drives the movable frame 44, the movable block 45 and the limit block 41 to move, so that the limit The block 41 contacts the sample, so that the two limit blocks 41 clamp and limit the sample. At this time, the pressure block 3 continues to move downward to contact the sample for pressure testing. The pressure block 3 continues to move downward, so that the slide bar 43 continues to push the movable frame 44 to move, so that the gas in the movable frame 44 is discharged through the outlet pipe 464 and squeezes the first spring 469, so that the movable block 45 will not drive the limit block 41 to continue to move in the direction close to the sample, ensuring that the two limit blocks 41 will not excessively clamp the sample.

[0026] like Figure 4 As shown, one side of the inner wall of the movable frame 44 is connected to an air inlet pipe 466, and the inner wall of the air inlet pipe 466 is fixedly connected to a one-way air inlet valve 467. When there is no external force against the first spring 469, the elastic force of the first spring 469 drives the movable block 45 to move in the movable frame 44, so that the outside air enters the movable frame 44 through the air inlet pipe 466 and the one-way air inlet valve 467.

[0027] like Figure 4As shown, the inner walls of the air outlet pipe 464 and the air inlet pipe 466 are fixedly connected with a filter 468. The filter 468 is used to prevent dust in the air from entering the movable frame 44 through the air inlet pipe 466 and to prevent dust from adhering to the one-way air inlet valve 467 and the one-way air outlet valve 465.

[0028] like Figure 3 One end of the slide bar 43 is fixedly connected to the second spring 4611, and the other end of the second spring 4611 is fixedly connected to one end of the inner wall of the slide cylinder 42. The pressure block 3 drives the air push frame 462 to move upward, and the elastic force of the second spring 4611 pushes the slide bar 43 to move away from the limit block 41, so that the gas in the slide cylinder 42 returns to the gas storage box 461 through the gas delivery pipe 463.

[0029] When the utility model is in use, a sample is placed in the test box 1, and the hydraulic cylinder 2 is started. The lower end of the bottom end of the hydraulic cylinder 2 drives the pressure block 3 to move downward. The downward movement of the pressure block 3 drives the air push frame 462 to move downward in the air storage box 461, so that the gas in the air storage box 461 is respectively transported to the two slide cylinders 42 through the air supply pipe 463. The excessive gas in the slide cylinder 42 pushes the slide rod 43, the movable frame 44, the movable block 45 and the limit block 41 to move, so that the limit block 41 contacts the sample, so that the two limit blocks 41 clamp and limit the sample. At this time, the pressure block 3 continues to move downward and contacts the sample to perform a pressure test. The pressure block 3 continues to move downward, so that the slide rod 43 continues to push the movable frame 44 to move, so that the gas in the movable frame 44 is discharged through the air outlet pipe 464 and squeezes the first spring 469, so that the movable block 45 will not drive the limit block 41 to continue to move in the direction close to the sample, thereby ensuring that the two limit blocks 41 will not excessively clamp the sample.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
