Description

Technical Field

[0001] The utility model belongs to the field of concrete testing equipment, and specifically relates to a sample cabinet for concrete performance testing. Background Art

[0002] During the construction process, in order to ensure the quality of the project, the concrete mix ratio will be fine-tuned according to the actual conditions of the construction site. In order to test the design strength of the concrete, the simplest method is to make concrete test blocks for inspection. Concrete test blocks are generally placed in a sample cabinet for storage.

[0003] At present, the existing concrete sample cabinets only have the function of storing concrete samples, but do not have the function of testing concrete samples. When conducting strength tests on concrete, the concrete still needs to be taken out of the sample cabinet and sent to the corresponding testing equipment. During the transportation process, changes in temperature and humidity will affect the performance of the concrete.

[0004] Therefore, in order to solve the problem that the existing concrete sample cabinet only has the function of storing concrete samples and is inconvenient to transport when performing performance testing on the concrete samples, and still needs to be taken out of the concrete sample cabinet, the existing concrete sample cabinet is improved to add the function of testing the strength of concrete samples. Utility Model Content

[0005] In order to overcome the problem that the existing concrete sample cabinet has too single function and can only be used to store concrete test blocks but cannot perform performance tests on the concrete test blocks.

[0006] The technical solution of the utility model is: a sample cabinet for concrete performance testing, including a sample cabinet composed of a support base and a dust cover with a plurality of equally spaced movable doors connected to the front side by hinges, a loading assembly, a clamping mechanism, a pressure detection mechanism, and a chip removal assembly; the loading assembly is arranged in the support base, the clamping mechanism for fixing the concrete test block is arranged on the support base, the pressure detection mechanism located above the clamping mechanism is arranged on the support base, and the chip removal assembly is arranged in the support base.

[0007] Preferably, a pressure detection mechanism is added to the sample cabinet, the concrete test block is moved to the detection platform through the loading assembly, the concrete test block is fixed by squeezing it left and right using the clamping mechanism, the pressure detection mechanism performs pressure detection on the concrete test block, and the chip removal assembly can collect the broken concrete test block fragments to prevent scratches on the test personnel.

[0008] Preferably, a storage box located inside the dust cover is provided on the support base, and a plurality of storage compartments arranged at equal distances are provided on the storage box. Concrete test blocks are placed in the storage compartments, and concrete labels are pasted on the back of the storage box. Multiple storage compartments can be used to store different concrete test blocks with consistent environmental requirements, and the labels can prevent the wrong concrete test blocks from being taken during testing.

[0009] Preferably, the loading assembly includes a loading box; the loading box is fixedly connected to the bottom end of the storage box, and a loading door is movably connected to the rear side of the loading box through a hinge. The design of the loading door allows the inspector to take out the concrete sample from the front side of the sample cabinet through the movable door and quickly put it into the loading box, reducing the time required for movement.

[0010] Preferably, the loading assembly also includes a loading block and a No. 1 cylinder; the loading block is arranged in the loading box, and the No. 1 cylinder is installed on the rear side of the loading box, and the loading block is connected to the piston rod of the No. 1 cylinder. After the No. 1 cylinder is started, the piston rod pushes the loading block forward, and the concrete test block placed on the front side of the loading block is squeezed out of the loading box and falls onto the supporting platform.

[0011] Preferably, the clamping mechanism includes a No. 2 cylinder and a clamping block; two No. 2 cylinders are installed on the supporting base opposite to each other on the left and right, the clamping block is connected to the piston rod of the No. 2 cylinder, and rubber pads are bonded to the opposite sides of the two clamping blocks. When the No. 2 cylinder is started, the two clamping blocks are pushed closer to each other, and the concrete test block in the middle is fixed by mutual squeezing.

[0012] Preferably, the pressure detection mechanism includes a lifting frame, a lifting platform, a No. 3 cylinder, and a pressure sensor; a lifting frame with a slide groove on the surface is installed on the supporting base, and the lifting platform is slidably connected in the slide groove; a No. 3 cylinder with a piston rod connected to the top of the lifting platform is installed on the lifting frame; a pressure sensor composed of an elastic element and a resistance strain gauge is installed under the lifting platform; after the No. 3 cylinder is started, it pushes the lifting platform and the pressure sensor to move downward on the lifting frame; after pressure is applied to the concrete test block, the elastic element will deform, causing the resistance value of the resistance strain gauge to change; by measuring the change in resistance value, the pressure of the concrete test block can be calculated.

[0013] Preferably, the chip removal assembly includes a chip box and a dust collector head; chip boxes with built-in fans are installed on the left and right sides of the support base, and a dust collector head connected to the chip box through an air duct is provided on the surface of the support base. The quality of concrete test blocks is not the same. Some concrete test blocks with weaker bearing capacity will crack during the pressure test stage. The cracked fragments can easily scratch the testers when the concrete test blocks are subsequently removed. The cracked fragments of the concrete test blocks are sucked into the chip box through the dust collector head for storage and await subsequent processing.

[0014] Beneficial effects of the utility model:

[0015] 1. By installing a pressure detection mechanism that can perform pressure tests on concrete test blocks inside the sample cabinet, the concrete to be tested is sent to the position of the clamping component by using the feeding component. After the clamping component fixes the concrete, the pressure detection mechanism performs pressure testing on it, thus adding a pressure detection function to the sample cabinet that can only be used for storage;

[0016] 2. During pressure testing, since different concrete test blocks have different bearing capacities, concrete test blocks with poor bearing capacities may crack during testing. The dust cover can prevent the cracked concrete fragments from splashing and injuring the observers, and the vacuum head can suck these fragments into the chip collection box to prevent the observers from being scratched when taking out the samples.

By adding the pressure detection mechanism 6 to the sample cabinet, the concrete test block is moved to the detection platform through the loading assembly 4, the concrete test block is fixed by squeezing the clamping mechanism 5 left and right, the pressure detection mechanism 6 performs pressure detection on the concrete test block, and the chip removal assembly 7 can collect the broken concrete test block fragments to prevent scratches on the detection personnel.

[0026] See also Figure 2-5 In this embodiment, a storage box 8 located inside the dust cover 3 is provided on the support base 1, and a plurality of storage compartments arranged at equal distances are provided on the storage box 8, and concrete test blocks are placed in the storage compartments. A concrete label is attached to the rear side of the storage box 8, and the loading assembly 4 includes a loading box 401; the bottom end of the storage box 8 is fixedly connected to the loading box 401, and the rear side of the loading box 401 is movably connected to a loading door through a hinge, and the loading assembly 4 also includes a loading block 402 and a No. 1 cylinder 403; a loading block 402 is provided in the loading box 401, and a No. 1 cylinder is installed on the rear side of the loading box 401 403, the loading block 402 is connected to the piston rod of the No. 1 cylinder 403. Multiple storage compartments can be used to store different concrete test blocks with consistent environmental requirements. Labels can prevent the wrong concrete test blocks from being taken during testing. The design of the loading door allows the tester to take out the concrete sample from the front side of the sample cabinet through the movable door 2 and quickly put it into the loading box 401, reducing the time required for movement. After the No. 1 cylinder 403 is started, the piston rod pushes the loading block 402 to move forward, and the concrete test block placed on the front side of the loading block 402 is squeezed out of the loading box 401 and falls onto the supporting platform.

[0027] See also Figure 4 , 6In this embodiment, the clamping mechanism 5 includes a No. 2 cylinder 501 and a clamping block 502; two No. 2 cylinders 501 opposite to each other are installed on the support base 1, and the clamping block 502 is connected to the piston rod of the No. 2 cylinder 501, and rubber pads are bonded to the opposite sides of the two clamping blocks 502. The pressure detection mechanism 6 includes a lifting frame 601, a lifting platform 602, a No. 3 cylinder 603, and a pressure sensor 604; a lifting frame 601 with a slide groove on the surface is installed on the support base 1, and the lifting platform 602 is slidably connected in the slide groove. The lifting frame 601 is equipped with a No. 3 cylinder 603 with a piston rod connected to the top of the lifting platform 602, and a pressure sensor 604 composed of an elastic element and a resistance strain gauge is installed under the lifting platform 602. The chip removal component 7 includes a chip collection box 701 and a dust collection head 702; chip collection boxes with built-in fans are installed on both sides of the support base 1 701. A dust collector head 702 connected to the chip box 701 through an air duct is provided on the surface of the support base 1. The No. 2 cylinder 501 is started to push the two clamping blocks 502 closer to each other, and the concrete test block in the middle is fixed by squeezing each other. After the No. 3 cylinder 603 is started, it pushes the lifting platform 602 and the pressure sensor 604 to move downward on the lifting frame 601. After pressure is applied to the concrete test block, the elastic element will deform, causing the resistance value of the resistance strain gauge to change. By measuring the change in resistance value, the pressure of the concrete test block can be calculated. The quality of concrete test blocks is not the same. Some concrete test blocks with weaker bearing capacity will crack during the pressure test stage. The cracked fragments are easy to scratch the tester when the concrete test block is taken out later. The cracked fragments of the concrete test block are sucked into the chip box 701 through the dust collector head 702 for storage and wait for subsequent processing.

[0028] When working, the staff first puts the prepared concrete test blocks into the storage compartment opened by the storage box 8 through the movable door 2, and labels them to prevent errors when taking them out later, takes out the concrete test blocks to be tested from the storage compartment, opens the loading door, puts the concrete test blocks in front of the loading block 402 in the loading box 401, closes the loading door, starts the No. 1 cylinder 403, and the piston rod of the No. 1 cylinder 403 pushes the loading block 402 and the concrete test blocks to move, and pushes the concrete test blocks out of the loading box 401 and falls onto the support platform;

[0029] Start the No. 2 cylinder 501, the piston rod of the No. 2 cylinder 501 pushes the clamping blocks 502 to move closer to each other, fixing the concrete test block in the middle, and then start the No. 3 cylinder 603, the piston rod of the No. 3 cylinder 603 drives the lifting platform 602 and the pressure sensor 604 installed under the lifting platform 602 to move downward on the lifting frame 601. After the concrete test block is pressurized, the elastic element of the pressure sensor 604 will be deformed, causing the resistance value of the resistance strain gauge to change. By measuring the change in resistance value, the pressure of the concrete test block can be calculated;

[0030] When the bearing capacity of the concrete block under test is weak, it will be compressed to crack. The dust cover 3 can block the fragments of the column. At this time, the fan in the chip box 701 can be started, and the dust suction head 702 can suck the cracked concrete block fragments into the chip box 701 for subsequent processing.

[0031] Through the above steps, a pressure detection mechanism 6 capable of performing pressure tests on concrete test blocks is installed inside the sample cabinet, and the concrete to be tested is delivered to the position of the clamping component by using the loading component 4. After the clamping component fixes the concrete, the pressure detection mechanism 6 performs pressure testing on it, thereby adding a pressure detection function to the sample cabinet that can only be used for storage, so as to solve the problem that the existing concrete sample cabinet is too single in function and can only be used to store concrete test blocks but cannot perform performance tests on the concrete test blocks.
