Description

Technical Field

[0001] The utility model relates to the technical field of concrete quality detection, in particular to a novel bridge concrete strength detection device. Background Art

[0002] Concrete refers to cement as the binder, sand and stone as aggregates, mixed with water in a certain proportion, and obtained through mixing, molding and curing. It is also called ordinary concrete. Concrete is the most common material in construction, and the hardness of concrete also determines the quality of the building.

[0003] After concrete is produced, it needs to be tested for hardness. However, existing testing equipment mostly uses hydraulic rods to squeeze concrete until it breaks, thereby obtaining the strength of the concrete. However, this testing method will cause a large amount of concrete impurities to fall when the concrete breaks, and the fallen impurities are likely to remain on the placement plate. If the impurities that fall on the concrete cannot be cleaned up in time, it will cause data deviation in the next concrete test.

[0004] In view of this, Chinese patent CN219608667U discloses a concrete hardness testing device, which ensures that the concrete blocks can be quickly removed after the test by providing a receiving cavity; and side baffles are provided around the placement plate to prevent the concrete blocks from splashing around when under pressure.

[0005] However, concrete is hard. When the pressure plate has been used for too long, it is often affected by external forces, resulting in a certain degree of damage or wear, which requires staff to replace it. Most existing concrete hardness detection devices directly install the pressure plate on the hydraulic cylinder or electric push rod. When the pressure plate is damaged, it is difficult for staff to replace it, which affects the normal operation of the detection device and further affects the work efficiency of the staff. Therefore, the present utility model is proposed to solve the above problems. Utility Model Content

[0022] See also Figures 1 to 3 A novel bridge concrete strength detection device in this embodiment includes a base 1, a box body 2 is fixedly installed on the upper surface of the base 1, a placement box 3 is fixedly installed on the back of the box body 2, a movable plate 4 is arranged on the upper surface of the base 1 and located inside the box body 2, a scraper 5 in contact with the upper surface of the base 1 is fixedly installed on the lower surface of the movable plate 4, an adjusting component connected to one side surface of the movable plate 4 is arranged inside the placement box 3, a hydraulic cylinder 6 is fixedly installed on the inner top wall of the box body 2, a mounting cover 7 is installed on the lower surface of the hydraulic cylinder 6, a pressing plate 8 is arranged on the lower surface of the mounting cover 7, and a connecting block 9 extending to the inside of the mounting cover 7 is fixedly installed on the upper surface of the pressing plate 8.

[0023] Both side surfaces of the mounting cover 7 are provided with fixing components for fixing the connecting block 9 , so as to facilitate replacement of the pressing plate 8 .

[0024] Example 1: Please refer to Figure 1 and Figure 3 In this embodiment, the fixing component includes a limiting cover 10 fixedly mounted on the surface of one side of the mounting cover 7, a pull rod 11 with one end extending to the inside of the limiting cover 10 is inserted on the side of the limiting cover 10 away from the mounting cover 7, a pull ring is fixedly mounted on the end of the pull rod 11 located outside the limiting cover 10, a limiting block 12 slidingly connected to the inner wall of the limiting cover 10 is fixedly mounted on the end of the pull rod 11 located inside the limiting cover 10, a clamping rod 13 with one end extending to the inside of the mounting cover 7 is fixedly mounted on the other side of the limiting block 12, and a spring 20 is sleeved on the surface of the pull rod 11 and located inside the limiting cover 10.

[0025] Among them, there are card slots on both the left and right sides of the connection block 9, and one end of the two card rods 13 located inside the installation cover 7 is card-engaged with the corresponding card slots, and the connection block 9 is card-engaged with the installation cover 7 through the two card rods 13.

[0026] When the staff observes that the pressure plate 8 is damaged, they pull the pull rings on both sides to make the pull rings drive the pull rod 11 to move, so that the pull rod 11 drives the clamping rod 13 to move away from the clamping slot through the limit block 12. When the clamping rod 13 is out of the clamping slot, the limit of the connecting block 9 is cancelled, so that the staff has to dismantle the damaged pressure plate 8 for replacement, thus avoiding the normal operation of the device.

[0027] Example 2: Please refer to Figure 1 and Figure 2 In this embodiment, the adjustment component includes a driving member arranged on the surface of one side of the placement box 3, one end of the driving member extends to the interior of the placement box 3 and a rotating shaft 14 is arranged on the surface, a threaded groove is opened inside the rotating shaft 14, the other end of the rotating shaft 14 extends to the interior of the box body 2 and is fixedly connected to the surface of one side of the movable plate 4, and a limiting member for limiting the rotating shaft 14 is arranged inside the placement box 3 and on the upper and lower sides of the rotating shaft 14.

[0029] Secondly, the limiting member includes a limiting rod 17 fixedly mounted on the inner wall of the placement box 3, and a slider 18 is slidably sleeved on the surface of the limiting rod 17. The other end of the slider 18 is fixedly connected to the surface of the rotating shaft 14. The rotating shaft 14 is limited by the slider 18, so that the rotating shaft 14 can move horizontally driven by the thread of the screw rod 16.

[0030] In addition, a collection box 19 is fixedly installed on the front of the base 1, and the top of the collection box 19 is an open structure.

[0031] When the concrete inspection is completed, there will be concrete blocks remaining on the upper surface of the base 1. At this time, the motor 15 drives the screw rod 16 to rotate, so that the screw rod 16 rotates and drives the rotating shaft 14 to move in the direction of the collection box 19, so that the rotating shaft 14 drives the moving plate 4 to move, and the moving plate 4 drives the scraper 5 to scrape the upper surface of the base 1, thereby scraping the concrete blocks into the collection box 19, so as to facilitate their collection and avoid data deviation during the next concrete inspection.

[0032] The working principle of the above embodiment is as follows: when the staff observes that the pressure plate 8 is damaged, the staff pulls the pull rings on both sides to make the pull rings drive the pull rod 11 to move, so that the pull rod 11 drives the clamping rod 13 to move away from the clamping slot through the limit block 12. When the clamping rod 13 is out of the clamping slot, the limit of the connecting block 9 is cancelled, so that the staff can dismantle the damaged pressure plate 8 for replacement, thereby avoiding the normal operation of the device.

[0033] When the concrete inspection is completed, there will be concrete blocks remaining on the upper surface of the base 1. At this time, the motor 15 drives the screw rod 16 to rotate, so that the screw rod 16 rotates and drives the rotating shaft 14 to move in the direction of the collection box 19, so that the rotating shaft 14 drives the moving plate 4 to move, and the moving plate 4 drives the scraper 5 to scrape the upper surface of the base 1, thereby scraping the concrete blocks into the collection box 19, so as to facilitate their collection and avoid data deviation during the next concrete inspection.

[0034] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
