Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection, in particular to a concrete compression resistance detection instrument. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. Before it is put into use, it is generally necessary to conduct a compression test to ensure that its strength can meet the standards of the application scenario.

[0003] At present, in the prior art, a Chinese patent with announcement number CN213121387U discloses a compression tester for concrete testing. The device can place a sample of a concrete block through a placing box, and then turn on the motor to control the motor to rotate forward. Under the action of the first belt pulley and the second belt pulley, the threaded pipe can be driven to rotate. The threaded pipe and the threaded rod can be used to drive the pressure block to move downward, thereby squeezing the concrete block sample in the placing box. The pressure sensor can be used to detect the pressure, thereby performing compression test on the concrete sample. The electric telescopic rod, the support rod, the slide rail and the slide table can be used to drive the placing box to tilt, and the discharge port can be used to facilitate people to discharge the debris, thereby facilitating the cleaning of the debris.

[0004] However, when the device is actually used, when cleaning the debris in the placement box, the placement box needs to be rotated and tilted so that the debris slides through the discharge port and is discharged. This method will cause some debris to remain in the placement box and cannot be cleaned thoroughly. In view of this, we propose a concrete compression tester. Utility Model Content

[0005] The main purpose of the utility model is to provide a concrete compression tester, which can solve the problems raised in the above background technology.

[0010] A one-way driving gear is penetrated by the rotating shaft and is rotatably connected to the rotating shaft. When the rotating shaft is driven by the one-way driving gear to rotate clockwise, the transmission gear can be driven to rotate clockwise, so that the rack rod is extended to push the push plate to move, which is convenient for the subsequent pushing out of the protective box, so that the staff can quickly clean out the debris in the protective box.

[0011] Preferably, an elastic telescopic rod is fixedly connected to the outer wall of the rotating shaft, and the telescopic end of the elastic telescopic rod is engaged with the ratchet inside the one-way driving gear.

[0012] Preferably, the downward pressure detection component includes a cylinder, a pressure sensor is fixedly connected to the output end of the cylinder, and a die is fixedly connected to the lower end of the pressure sensor. The die is driven downward by the output end of the cylinder to squeeze the concrete in the protective box, and the pressure resistance detection of the concrete is achieved by using the pressure sensor.

[0013] Preferably, a gear rod is fixedly connected to the outer wall of the die, and the gear rod and the one-way driving gear are in the same horizontal plane, a guide rod is fixedly connected to the upper side of the die, and a wedge block is fixedly connected to the lower side of the die.

[0014] Preferably, a trapezoidal groove is provided on the outer wall of the operating table, a through opening is provided on the outer wall of the operating table, and the through opening matches the rack rod, and the normal lifting and lowering of the rack rod can be ensured by using the through opening.

[0016] The utility model provides a concrete compression tester, which has the following beneficial effects:

[0017] (1) The concrete compression tester uses a downward pressure detection component and a pushing mechanism to ensure that the pressing die can ensure the stability of the pressed concrete when pressing the concrete block. When the pressing die rises and resets, the pushing plate can push the protective box out, making it convenient for the staff to completely clean the debris in the protective box. After the pressing die is reset, the pushing plate can automatically reset, facilitating subsequent continuous work.

[0018] (2) The concrete compression tester uses trapezoidal grooves, trapezoidal blocks and wedge-shaped blocks to ensure that the protective box is in a stable state when the die presses down the concrete block, preventing the protective box from moving, thereby ensuring that the device can stably test the concrete compression resistance.

Through the use of the pushing mechanism 4, the concrete block in the protective box 2 can be automatically pushed out after the detection is completed, so that the subsequent staff can clean up the concrete debris in the protective box 2.

[0031] In order to be able to perform a compressive test on the concrete in the protection box 2, specifically, the downward pressure detection component 3 includes a cylinder 31, a pressure sensor 32 is fixedly connected to the output end of the cylinder 31, a die 33 is fixedly connected to the lower end of the pressure sensor 32, a gear rod 35 is fixedly connected to the outer wall of the die 33, a guide rod 34 is fixedly connected to the upper side of the die 33, and a wedge block 36 is fixedly connected to the lower side of the die 33.

[0032] Furthermore, in order to be able to transport the protection box 2 out after the concrete block is inspected, so that the staff can completely clean the debris in the protection box 2 and then put in new concrete blocks, specifically, the pushing mechanism 4 includes a support plate 41, the support plate 41 is fixedly connected to the outer wall of the operating table 1, a sleeve rod 42 is fixedly connected to the outer wall of the support plate 41, and the sleeve rod 42 is sleeved with a rack rod 43, a trapezoidal groove 101 is opened on the outer wall of the operating table 1, a through opening is opened on the outer wall of the operating table 1, and the through opening is matched with the rack rod 43, and the lower side of the protection box 2 is fixedly connected A trapezoidal block 21 is connected, and the trapezoidal block 21 matches the trapezoidal groove 101.

The end of the rack rod 43 away from the sleeve rod 42 is fixedly connected to a push plate 44, and the push plate 44 is elastically connected to the support plate 41 through a reset spring 45. The rack rod 43 is meshed with a transmission gear 46, and the transmission gear 46 is penetrated by the rotating shaft 48 and is connected to the support plate 41. The rotating shaft 48 is fixedly connected, and the rotating shaft 48 passes through the one-way driving gear 47 and is rotatably connected to the rotating shaft 48.

When the die 33 rises and resets, the gear rod 35 drives the one-way driving gear 47 to rotate clockwise. At this time, the telescopic end of the elastic telescopic rod 481 is limited, so that the rotating shaft 48 drives the transmission gear 46 to rotate, thereby making the gear rod 35 extend and push the push plate 44 to move, which is convenient for the subsequent ejection of the protective box 2, so that the staff can quickly clean out the debris in the protective box 2.
