Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a device for detecting the compressive strength of concrete. Background Technique

[0002] Concrete is usually made by mixing cement, sand, gravel and water, and then it becomes concrete after hardening. It is commonly used in building construction. As a building material, in order to ensure the quality and safety of the house after concrete construction, we usually use concrete strength detection equipment to detect the concrete strength.

[0003] After retrieval, the utility model patent with the publication number of CN216560033U discloses a concrete pressure detection device, which includes a power box, a control unit, a base, a column, a motor, a lifting pressure plate, an experimental pressure plate, an outer frame body, an adjustment turntable, and a double-layer protective door. The motor drives the lifting pressure plate to move up and down. An experimental pressure plate is installed above the lifting pressure plate through a lead screw connection of the adjustment turntable. The outer frame body is connected and installed with a double-layer protective door using a rotating shaft. A concrete pressure detection device, the design of this device is suitable for the pressure test experiment of concrete. Place the standard concrete soil sample on the lifting pressure plate. The power box drives the motor to move. The concrete between the lifting pressure plate and the experimental pressure plate is subjected to pressure extrusion for testing. The protective interception net is woven from composite plastic material, with high strength and good elastic coefficient, which can effectively intercept the flying concrete stones at high speed. When the protective interception net is deformed by external force impact, the traction spring is elastically deformed to make a certain structural buffer. The tempered glass observation window is designed for secondary protection and experimental observation; although this device can block the concrete debris, when it is used, due to the setting of the protective door, the workbench is in a three-sided closed state, so it is more inconvenient to clean the residual fragments on the workbench and the lifting pressure plate, and it is difficult to clean them thoroughly. Secondly, due to the setting of the protective door, it is more inconvenient to place the concrete test block, so this device still has certain deficiencies. Summary of the Utility Model

Embodiment

[0024] Refer to Figures 1 - 4, a device for detecting the compressive strength of concrete, comprising a bottom cabinet 100 and a workbench 101 arranged on the top of the bottom cabinet 100. On the top of the workbench 101, there are a pressure-bearing platform 102, a support frame 200 and a strength detection equipment body 300. At the top of the support frame 200, there is a driving component 400. The output end of the driving component 400 passes through the support frame 200 and is connected to a first connecting plate 500. At the bottom of the first connecting plate 500, there is a pressure-applying plate 501. On both sides of the first connecting plate 500, there are elastic connection components 600. The output end of the elastic connection component 600 is connected to a protective cover 700 for preventing debris from splashing everywhere. Inside the bottom cabinet 100, there is an aggregate frame 103 for collecting debris and a tool storage cabinet 104.

[0025] The support frame 200 includes a support column 201 arranged on the top of the workbench 101 and a top plate 202 arranged on the top of the support column 201.

[0026] The driving component 400 includes a hydraulic cylinder 401 fixedly arranged on the top of the top plate 202 and having its output end fixedly connected to the first connecting plate 500, and a guide rod 402 having one end fixedly connected to the first connecting plate 500 and the other end passing through the top plate 202 and extending upward.

[0027] The elastic connection component 600 includes a fixed plate 601 fixedly connected to the side of the first connecting plate 500, a connecting rod 602 passing through the fixed plate 601, and a second connecting plate 603 arranged at the bottom of the connecting rod 602 and slidably connected to the support column 201. Among them, a limit block 604 is arranged at the top of the connecting rod 602, and an elastic member 605 is sleeved on the outer wall of the connecting rod 602. The elastic member 605 is fixedly connected between the fixed plate 601 and the limit block 604. By arranging the elastic connection component 600, it can not only drive the protective cover 700 to move downward when the first connecting plate 500 moves downward to achieve a good protection effect, but also avoid affecting the normal pressure application operation of the pressure-applying plate 501 on the concrete test block. Secondly, under the connection action of the elastic connection component 600, when the first connecting plate 500 moves upward, it can drive the protective cover 700 to move upward away from the workbench 101, so as to facilitate the cleaning of the broken concrete debris and the placement of the concrete test block.

[0028] In order to ensure that the first connecting plate 500 and the pressure-applying plate 501 can apply pressure to the concrete test block to achieve detection, a through groove 502 matching the first connecting plate 500 and the pressure-applying plate 501 is opened on the second connecting plate 603, so that the pressure-applying plate 501 can act on the concrete test block.

[0029] The protective cover 700 is detachably connected to the bottom of the second connecting plate 603 by connecting bolts 701, and a flexible rubber pad 702 is arranged at the bottom of the protective cover 700. The protective cover 700 is detachable, so when the protective cover 700 is damaged or needs to be cleaned, it can be easily replaced or cleaned. The setting of the flexible rubber pad 702 can avoid damage to the surface of the workbench 101.

[0030] A material discharge chute 105 is provided on the top of the workbench 101 to facilitate cleaning of the debris on the workbench 101 into the collection frame 103 for unified collection.

[0031] Specifically, when the present concrete compressive strength testing device is in use: when in use, the concrete test block to be tested is placed on the top of the pressure platform 102, and the hydraulic cylinder 401 is started to cooperate with the guide rod 402 to drive the first connecting plate 500 connected thereto to move downward, thereby driving the pressure plate 501 to move downward. Through the elastic connecting assembly 600, when the first connecting plate 500 moves downward, it will drive the fixed plate 601 of its side wall to move downward, thereby driving the second connecting plate 603 and the protective cover 700 connected to its bottom to move downward. Since the protective cover 700 is arranged at the bottom of the second connecting plate 603, the bottom of the protective cover 700 first contacts the workbench 101, and the connecting rod 602 and the elastic member 605 are cooperated. When the bottom of the protective cover 700 contacts the workbench 101, the first connecting plate 500 and the pressure plate 501 can be driven by the hydraulic cylinder 401 to continue to move. It continues to move downward and abut against the concrete test block placed on the top of the pressure platform 102 and apply pressure, and then the test data is obtained through the strength testing equipment body 300. After the test, the hydraulic cylinder 401 is started to drive the first connecting plate 500 to move upward and retract. When the first connecting plate 500 rises to a certain height, the elastic connecting component 600 is provided in conjunction with it, and then drives the second connecting plate 603 connected thereto and the protective cover 700 provided at the bottom thereof to move upward along the support column 201. At this time, the workbench 101 and the pressure platform 102 are in an unobstructed state, which is convenient for cleaning the concrete debris on the top and placing the concrete test block. At the same time, it can play a good protective effect when performing pressure testing. Furthermore, the discharge chute 105 and the aggregate frame 103 provided in conjunction with it can uniformly collect and clean the debris of the concrete test block broken after the test.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
