Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a building material compression resistance detection device. Background Art

[0002] As a commonly used material in construction projects, the hardness and compressive strength of concrete are very important indicators, which play a very important role in the quality of the project. The compressive strength test of concrete is generally carried out before the construction of concrete. The concrete mix ratio is tested, the concrete is made into samples, and then the test is pressurized with the corresponding pressure device. The stress of the sample during the pressurization process is measured by the relevant detection device, so as to judge the compressive performance of concrete building materials.

[0003] The testing process is generally as follows: place the air-dried concrete block in the center of the wall of the extrusion sleeve, and then drive the multi-stage hydraulic press through the hydraulic driver, so that the multi-stage hydraulic press drives the extrusion drive plate below it to extrude the concrete block on the wall of the extrusion sleeve until the concrete block is broken. During the extrusion process, the pressure data is recorded by the pressure sensor and transmitted to the computer through the data transmission line, so as to test the compressive performance of concrete building materials.

[0004] In the actual testing process of concrete building materials, a protective cover is usually added on the outside to prevent the fragments generated when the concrete is broken from splashing and injuring people. Over time, the protective cover will be covered with debris and dust, which is not conducive to the subsequent observation of the concrete breakage. For this reason, we propose a building material compression testing device. Utility Model Content

DETAILED DESCRIPTION

[0022] 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] A protective cover 4 is fixed on the support plate 22 and is provided with an observation hole 41;

[0025] A pressurizing mechanism 5, which is mounted on the multi-stage hydraulic rod 3, and applies a uniform force to the top of the material through the multi-stage hydraulic rod 3;

[0026] The scraping mechanism 6 is installed on the protective cover 4 and connected to the pressurizing mechanism 5 . The scraping mechanism 6 supports the material and scrapes the debris on the protective cover 4 under the pressure of the pressurizing mechanism 5 .

[0027] The pressurizing mechanism 5 includes a pressing plate 51 installed on the top of the multi-stage hydraulic rod 3, and a support rod 52 is installed on the pressing plate 51. There are four support rods 52, which are respectively located at the four corners of the pressing plate 51, and circular blocks 53 are installed on the top of each support rod. A cylindrical groove 54 is opened on the base 21, and the cylindrical groove 54 passes through the support plate 22.

[0028] The scraping mechanism 6 includes a placement plate 61 mounted on the support rod 52 . The four corners of the placement plate 61 are penetrated by the support rod 52 . The length and width of the placement plate 61 are smaller than the protective cover 4 . The scraping mechanism 6 also includes a scraping member 7 mounted on the placement plate 61 .

[0029] The scraping member 7 includes a sleeve 71 fixed on one side of the placement plate 61, a shaft 72 is installed in the sleeve 71, both ends of the shaft 72 are sleeved with sleeves 73, a scraper 74 is installed on the sleeve 73, the scraper 74 is trapezoidal, both ends of the shaft 72 are sleeved with torsion springs 75, one end of the torsion spring 75 is fixed to the shaft 72, and the other end is fixed to the sleeve 73.

[0030] A collecting plate 8 is installed through the main frame 2 , and the collecting plate 8 is penetrated by the protective cover 4 .

[0031] During the raising of the placing plate 61, the scraper 74 gradually returns to its original position under the action of the torsion spring 75. Even if some of the scraped debris falls off, it will fall onto the collecting plate 8. The existence of the collecting plate 8 also provides a support platform when the workers clean the materials later.

[0032] The edges of the scraper 74 are chamfered to make the scraping of the protective cover 4 smoother.

[0033] The working principle of the utility model is as follows: the material is placed on the placement plate 61. Due to the restriction of the torsion spring 75 on the scraper 74, the scraper 74 covers the edge of the protective cover 4, and the placement plate 61 does not move downward. Then the multi-stage hydraulic rod 3 is turned on, and the multi-stage hydraulic rod 3 drives the pressure plate 51 to move downward. After the pressure plate 51 contacts the material, a strong pressure is applied to the material. Under this action, the torsion spring 75 drives the scraper 74 to rotate. The supporting force of the scraper 74 on the protective cover 4 is much smaller than the pressure applied by the multi-stage hydraulic rod 3. The material drives the placement plate 61 to move downward synchronously. After the bottom end of the placement plate 61 contacts the support plate 22, the placement plate 61 cannot move at this time, and the multi-stage hydraulic rod 3 continues to Apply pressure and turn on the control terminal 1 to collect the detection data. After the detection is completed, the multi-stage hydraulic rod 3 rises upward. During the rising process of the pressure plate 51, the circular block 53 at the top of the support rod 52 fits with the bottom end of the placement plate 61, and then drives the placement plate 61 to rise upward. During this process, the torsion spring 75 is always in a force storage state, so that the scraper 74 is in close contact with the inner wall of the protective cover 4, and the debris and stains on the protective cover 4 will be scraped during the rising process. When the placement plate 61 just leaves the inside of the protective cover 4, the scraper 74 returns to its original position, and some debris may fall onto the collection plate 8. The staff can clean the debris on the placement plate 61 and the support plate 22.
