Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a concrete compressive strength testing device. Background Technology

[0002] A concrete compressive strength testing device is a specialized instrument used to determine the compressive strength of concrete test blocks. It mainly consists of a robust main frame, two parallel and flat pressure plates, and a hydraulic system that provides stable pressure. During testing, a standard-sized concrete test block is placed on the lower pressure plate, and the upper pressure plate, driven by the control system, applies uniform and continuous pressure to the block until it fails. The maximum failure load is recorded in real time. The concrete compressive strength testing device is an important indicator for evaluating the performance of concrete structures and the quality of engineering projects.

[0003] A concrete compressive strength testing device disclosed in Chinese Patent Publication No. CN216816263U, by setting up a testing mechanism and a protective mechanism on a workbench, allows for the testing of concrete test blocks. First, the concrete test block is placed on the workbench, and then pressure is applied to the concrete test block through the testing mechanism. The protective mechanism isolates the concrete test block from the outside environment, reducing the possibility of debris splashing and posing a danger to workers when the concrete test block breaks, thus improving the safety of workers during the testing process. However, the testing device lacks flexibility in use; after testing the concrete block, it is not convenient to quickly remove the concrete block debris, thus affecting the speed and convenience of subsequent concrete block testing and the overall effectiveness of the testing device. Utility Model Content

[0004] The purpose of this invention is to provide a concrete compressive strength testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete compressive strength testing device, comprising a workbench, a collection trough being provided inside the top left side of the workbench, a pressure plate being rotatably connected to the center of the inner surface of the workbench, a fixing frame being fixedly connected to the center of the rear end of the upper surface of the workbench, a hydraulic cylinder being fixedly connected to the center of the front end of the upper surface of the fixing frame, a pressure detection block being fixedly connected to the bottom end of the hydraulic cylinder, a protective frame being provided outside the pressure detection block, and further comprising a reset mechanism and a discharge mechanism, wherein the reset mechanism is used for resetting the protective frame, and the discharge mechanism is used for quickly collecting and cleaning the concrete block after testing.

[0006] Preferably, a discharge port is provided on the right side of the top of the collection tank, and a discharge port is fixedly connected to the bottom of the left side of the collection tank.

[0007] Preferably, the reset mechanism includes sliding rods fixed to the left and right sides inside the protective frame, sliders slidably connected to the outside of the sliding rods, springs fixed to the bottom of the sliders, and pressure detection blocks fixed to the inner sides of the two sliders.

[0008] Preferably, the discharge mechanism includes a first pull rope fixed to the right side of the lower surface of the pressure plate, a connecting arm fixed to the top right side of the protective frame, a second pull rope fixed to the right side of the lower surface of the connecting arm, a pressure plate fixed to the bottom end of the second pull rope, a take-up roller rotatably connected to the right side inside the workbench, the outside of the take-up roller fixed to the bottom end of the first pull rope, a torsion spring fixed to the front end of the take-up roller, the front end of the torsion spring fixed to the workbench, a first chain disk fixed to the rear end of the take-up roller, a chain meshing with the outside of the first chain disk, a second chain disk meshing with the inside of the left side of the chain, and a fan blade fixed to the front end of the second chain disk.

[0009] Preferably, the first pull rope has multiple strands wound clockwise on the take-up roller, and the front end of the agitator rotates inside the collection trough.

[0010] Preferably, all electrical equipment inside the detection device is started and controlled by an external controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This concrete compressive strength testing device features a protective frame around the pressure testing block. When the pressure testing block moves downwards, the protective frame covers the tested concrete block, effectively protecting it during testing. When the test is complete, the pressure testing block moves the protective frame upwards. At this time, the connecting arm on one side of the protective frame can lift the right side of the pressure plate via a second pull rope. The tested concrete block on the pressure plate then slides into the collection trough due to gravity. Simultaneously, the lifting of the pressure plate causes the take-up roller to rotate clockwise via the first pull rope. This turn-up roller then rotates the first chain wheel, which in turn drives the second chain wheel and the actuating fan blades to rotate via a chain. The actuating fan blades then push the concrete block in the collection trough from right to left, effectively preventing the concrete block from accumulating on the right side of the collection trough and significantly improving the overall functionality and ease of use of the testing device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a concrete compressive strength testing device, including a workbench 1, a collection trough 101 inside the top left side of the workbench 1, a pressure plate 2 rotatably connected to the center of the inner surface of the upper surface of the workbench 1, a fixed frame 3 fixedly connected to the center of the rear end of the upper surface of the workbench 1, a hydraulic cylinder 301 fixedly connected to the center of the front end of the upper surface of the fixed frame 3, a pressure detection block 4 fixedly connected to the bottom end of the hydraulic cylinder 301, a protective frame 5 provided outside the pressure detection block 4, and also includes a reset mechanism 6 and a discharge mechanism 7. The reset mechanism 6 is used for the reset of the protective frame 5, and the discharge mechanism 7 is used for the rapid collection and cleaning of concrete blocks after testing. The collection trough 101 can centrally collect and process the broken concrete blocks.

[0020] A discharge port 102 is provided on the right side of the top of the collection tank 101, and a discharge port 103 is fixed to the bottom of the left side of the collection tank 101. When the discharge port 103 is opened, the concrete blocks in the collection tank 101 can be quickly discharged.

[0021] The reset mechanism 6 includes slide rods 601 fixed to the left and right sides inside the protective frame 5. Slider 602 is slidably connected to the outside of slide rods 601. Spring 603 is fixed to the bottom end of slider 602. The inner sides of the two sliders 602 are fixed to pressure detection block 4. When the protective frame 5 moves downward and contacts the table surface, the slider 602 can slide on slide rod 601 and squeeze spring 603. When pressure detection block 4 drives the protective frame 5 away from the table surface, the reaction force of the squeezed spring 603 can push the protective frame 5 to reset quickly.

[0022] The discharge mechanism 7 includes a first pull rope 201 fixed to the right side of the lower surface of the pressure plate 2; a connecting arm 501 fixed to the top right side of the protective frame 5; a second pull rope 502 fixed to the right side of the lower surface of the connecting arm 501; a pressure plate 2 fixed to the bottom end of the second pull rope 502; a take-up roller 701 rotatably connected to the right side inside the workbench 1; the outside of the take-up roller 701 fixed to the bottom end of the first pull rope 201; a torsion spring 702 fixed to the front end of the take-up roller 701; the front end of the torsion spring 702 fixed to the workbench 1; a first chain disc 703 fixed to the rear end of the take-up roller 701; a chain 704 meshing with the outside of the first chain disc 703; a second chain disc 705 meshing with the inside of the left side of the chain 704; and a lever fixed to the front end of the second chain disc 705. When the fan blade 706 and pressure detection block 4 lift the protective frame 5, the connecting arm 501 on one side of the protective frame 5 can lift the right side of the pressure plate 2 by pulling the second pull rope 502. At this time, the concrete block on the pressure plate 2 can fall into the collection trough 101 due to gravity. At the same time, the pressure plate 2 pulls the winding roller 701 to rotate by the first pull rope 201. When the winding roller 701 twists the torsion spring 702, it can drive the first chain disc 703 to rotate. At this time, the first chain disc 703 can drive the second chain disc 705 to rotate synchronously with the fan blade 706 by the chain 704. When the first pull rope 201 releases the pull on the winding roller 701, the reaction force of the torsion spring 702 can drive the winding roller 701 to quickly wind up.

[0023] The first pull rope 201 has multiple strands wound clockwise on the take-up roller 701, which causes the front end of the fan blade 706 to rotate inside the collection trough 101.

[0024] All electrical equipment inside the testing device is started and controlled by an external controller. In addition, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0025] In this embodiment, the concrete block to be tested is placed directly below the pressure testing block 4 at the top of the pressure plate 2. The hydraulic cylinder 301 is then activated to push the pressure testing block 4 and the protective frame 5 downwards. The protective frame 5 then covers the outside of the concrete block. Simultaneously, the pressure testing block 4, in conjunction with the pressure plate 2, performs the compressive strength test on the concrete block. After the test, the hydraulic cylinder 301 drives the pressure testing block 4 upwards, which in turn lifts the protective frame 5. At this point, the connecting arm 501 on one side of the protective frame 5 can be raised via the second pull rope 502. When the right side of the pressure plate 2 is tilted, the concrete block that has been tested on the pressure plate 2 can slide into the collection tank 101 due to gravity. At this time, during the lifting process of the pressure plate 2, the first pull rope 201 at the bottom of the pressure plate 2 can pull the winding roller 701 to rotate. At this time, the winding roller 701 drives the first chain disc 703 to rotate. The first chain disc 703 can drive the second chain disc 705 and the agitator blade 706 to rotate synchronously through the chain 704. The agitator blade 706 can push the concrete block in the collection tank 101 to move from right to left to prevent the concrete block from accumulating inside the collection tank 101.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
