The invention discloses a test block protection and cleaning device for a concrete compressive strength detection test. The protective cover is connected to the second driving device and can be lifted up and down. The first driving device drives the protective cover and the second driving device to move horizontally into the space between the pressure-bearing plate and the pressure-applying plate. When the protective cover is in a high position, its lower end surface is higher than the test piece. , the automatic feeding device can transport the test block to the pressure-bearing plate. When the protective cover is in a low position, its lower end abuts on the pressure-bearing plate to surround the test block and form a closed space on the surface of the pressure-bearing plate to prevent the test. The waste generated by the broken concrete test block splashes; the protective cover is driven by the driving device and can gradually leave the bearing plate and the pressure plate, and remove the waste to the waste recovery device. It solves the problem that automatic feeding, automatic cleaning of test waste, and protection against splash of test waste cannot be taken into account at the same time.
Description
Technical Field
The invention belongs to the technical field of concrete test equipment, and particularly relates to a test block anti-splashing and cleaning device for a concrete compressive strength detection test.
Background
In the building engineering, the concrete used needs to be subjected to performance tests, including the test of the compression resistance, and the concrete method is as follows: pouring a batch of concrete test blocks in a special mould, then placing the concrete test blocks in a pressure tester, extruding the concrete test blocks through the tester until the test blocks are broken, and recording various parameters in the process to obtain the compression resistance of the concrete.
The traditional concrete pressure testing machine can generate the problems of fragment splashing and scattering during testing, thereby not only increasing the strength of later cleaning work, but also possibly causing safety accidents. Therefore, the patent document with the publication number of CN207268696U provides a concrete compression testing machine, which comprises a base and a top frame, wherein four pillars are vertically arranged between the base and the top frame, a pressure applying table and a driving cylinder for driving the pressure applying table to lift along the vertical direction are movably arranged on the top frame, a pressure bearing table is arranged on the base, a rectangular protective cover is arranged between the base and the top frame, the pressure applying table and the pressure bearing table are both positioned in the protective cover, the protective cover is fixedly arranged on the four pillars, and a cover door is hinged on the protective cover; when carrying out concrete pressure test, both can prevent that the fragment that splashes from injuring other people, also can avoid the fragment to splash to ground, through setting the cover door to convertible structure, can discharge the fragment on the pressure-bearing bench with the help of the cover door, convenient clearance. However, in the prior art, because the protective cover and the cover door are arranged on the periphery of the four pillars, the generated debris still falls into the gap between the protective cover and the pillars during the test, so that the protective cover and the cover door are difficult to clean completely during cleaning; and because the protection casing sets firmly on four spinal branch posts, this technical scheme can't be applied to automatic feeding's testing machine. Similar constructions also have a compression tester disclosed in CN 206504952U and a concrete compression tester disclosed in CN 206146744U, but all suffer from the same disadvantages.
Above-mentioned technical scheme still has the problem that needs the artifical clearance waste material, the improved design of automatic clearance waste material has been proposed for this someone, a compression testing machine as disclosed in CN 210719979U, which comprises a frame, pressure disk under the fixedly connected with in the frame, the top of lower pressure disk is equipped with the pressure disk, go up pressure disk and frame sliding connection, it is connected with the driving piece that the pressure disk removed in the drive to go up the pressure disk, be provided with the cleaning device of clearance disintegrating slag on the lower pressure disk, cleaning device includes scraper blade and brush cleaner, the top surface butt of brush cleaner and lower pressure disk, the brush cleaner is connected with the drive assembly that the brush cleaner removed at lower pressure disk top surface, the scraper blade is located the direction that the brush cleaner removed and brush cleaner fixed connection, the bottom surface of scraper blade and the top surface butt of lower pressure disk, be provided with waste material box in the frame. The driving assembly drives the cleaning brush and the scraper to clean the broken slag on the top surface of the lower pressing plate, so that the lower pressing plate can test the next concrete test block. After each concrete test block is tested, the cleaning device can clean the broken slag on the lower pressing disc. But the scraps generated in the test process still can be splashed and scattered into the gap between the protective cover and the support, so that the thorough cleaning is difficult to realize in the cleaning process; waste material box is too little, only can collect the piece of test block, and big test block waste material can not hold down, even can hold, experimental not long-time just need be shut down and empty the waste residue, influence test efficiency.
In order to solve the problems in the prior art, the applicant also provides a corresponding solution, for example, the press with the protection cover disclosed in CN210803128U, includes a press and a protection cover mechanism disposed on the press, the protection cover mechanism includes a protection driving cylinder, a protection connecting assembly and a protection cover body, the protection driving cylinder is mounted on a pillar of the press through a protection bracket, a power output end of the lower end of the protection driving cylinder is connected with the protection cover body through the protection connecting assembly, the protection cover body is disposed around an execution end of the press, and a rubber strip is disposed at the lower end of the protection cover body. When the press machine works, the protection driving cylinder firstly drives the protection cover body to move downwards to form protection around the sample material, and then the execution end of the press machine moves downwards to carry out strength detection on the sample; therefore, even the tiny particles are splashed in the test, the tiny particles can be blocked by the protective cover body, and the dust or the tiny particles of the sample are prevented from flying forwards. After the test is finished, the protective driving cylinder drives the protective cover body to move upwards, then the cleaning mechanism works (see paragraph 0043 of the specification of a novel press machine test device of CN 210803127U for details), sample residues are pushed to the discharging conveying table and are output to the outside through the discharging conveying table, and the cleaning mechanism and the discharging conveying table are oppositely arranged on two sides of the working table of the tester; and finally, pushing the next test block to the workbench by the pushing mechanism, positioning by the sample positioning and placing mechanism, and repeating the procedure by the testing machine to test the next test block. Therefore, after the protection driving cylinder drives the protection cover body to move upwards, the requirements of automatic feeding and waste material removal can be met, the automation degree and the test efficiency are improved, and the following defects still exist; secondly, the cleaning mechanism can also have some waste materials to scatter downwards from the both sides of test bench in-process with sample residue propelling movement to the transport platform of unloading, and the clearance is incomplete.
Therefore, the technical schemes can not simultaneously meet the requirements of protection of test waste splashing, automatic cleaning of the test waste and no influence on automatic feeding.
