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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a strength testing device for precast concrete components, including a base 1 and a top plate 4. A placement platform 2 is provided on the base 1, and a test specimen is placed on the placement platform 2. A hydraulic component 5 and a protective component 6 are provided on the top plate 4. The hydraulic component 5 includes a hydraulic cylinder 51 and a pressure sensor. One end of the push rod of the hydraulic cylinder 51 is fixedly connected to a pressure block 52. The protective component 6 includes an electric cylinder 61. One end of the push rod of the electric cylinder 61 is fixedly connected to a protective cover 62. A cleaning component 7 is provided on one side of the base 1. The cleaning component 7 includes a scraper 76, which is driven by a motor 72.

[0025] The specimen to be tested is placed on the placement platform 2. The electric cylinder 61 drives the protective cover 62 at one end to move downward and cover the specimen. The hydraulic cylinder 51 drives the pressure block 52 at one end to move, and the pressure block 52 of the hydraulic component 5 applies pressure to the specimen until the specimen is destroyed. The strength of the specimen is tested based on the pressure applied by the hydraulic component 5, thereby realizing the strength test of the precast concrete component.

[0026] When the motor 72 is working, it drives the scraper 76 to move. During the movement of the scraper 76, the upper surfaces of the base 1 and the placement platform 2 are cleaned.

[0027] The specimen is covered by a protective cover 62. When the specimen breaks, the concrete fragments generated by the protective cover 62 are intercepted, preventing debris from flying and improving the safety of the testing process. After the test is completed, the hydraulic component 5 and the protective component 6 move upward and reset. Then, the debris is cleaned by the cleaning component 7 and driven into the slag hopper 8 to ensure that there is no debris residue on the base 1 and the placement platform 2, so as to prepare for the next test. There is no need for manual cleaning of debris, saving time and effort.

[0028] Hydraulic cylinder 51 is connected to the drive system and is installed at the top of the top plate 4.

[0029] The drive system includes a hydraulic pump, relief valve, directional valve, oil tank, oil pipes, etc. Multiple pressure sensors are installed. One set of pressure sensors is installed at the pump outlet to monitor the maximum system pressure, another set of pressure sensors is installed after the valve to monitor the actual loading pressure, and a third set of pressure sensors is installed at the cylinder inlet to provide feedback on the input pressure of the actuator. Axial pressure is applied to the test block through the hydraulic assembly 5 until the test block fails. The maximum bearing capacity is recorded and the strength is calculated to achieve the strength test of the precast concrete component.

[0030] The protective cover 62 is provided with a viewing window 63. The electric cylinder 61 is installed at the top of the top plate 4, and the protective cover 62 is located at the bottom of the top plate 4. The protective cover 62 is driven by the electric cylinder 61. When the protective cover 62 is placed on the specimen, the specimen can be observed through the viewing window 63 of the protective cover 62 to intuitively understand the state of the specimen.

[0031] The cleaning component 7 includes a U-shaped frame 71, a motor 72 is mounted on one end face of the U-shaped frame 71, the output shaft of the motor 72 is fixedly connected to a lead screw 73, a slide rod 74 is provided on the U-shaped frame 71, and the slide rod 74 is located on one side of the lead screw 73. Both the lead screw 73 and the slide rod 74 pass through a slide table 75, and the slide table 75 and the slide rod 74 are slidably connected.

[0032] The slide table 75 is fixedly connected to the scraper 76, which is located on the upper surface of the base 1.

[0033] The base 1 has a slag collection hopper 8 at its front end.

[0034] When the motor 72 is working, it drives the lead screw 73 at one end to rotate, which in turn drives the slide table 75 to slide along the slide rod 74. The slide table 75 drives the scraper 76 to slide synchronously along the slide rod 74. During the movement, the scraper 76 cleans the upper surface of the base 1 and the placement platform 2, scraping the debris generated when the test block is crushed into the slag collection hopper 8, and collecting the debris in a concentrated manner through the slag collection hopper 8.

[0035] The upper surfaces of the base 1 and the placement platform 2 are located on the same horizontal plane. The lower part of the scraper 76 contacts the upper surfaces of the base 1 and the placement platform 2. When the upper surfaces of the base 1 and the placement platform 2 are cleaned by the scraper 76, the cleaning quality is improved.

[0036] The base 1 and the top plate 4 are fixedly connected by the column 3, and the base 1, the column 3 and the top plate 4 constitute the detection frame structure of the overall device.

[0037] A connecting block is fixedly installed on the side of the protective cover 62, and the connecting block is fixedly connected to the push rod of the electric cylinder 61. When the electric cylinder 61 is working, it drives the connecting block, which in turn drives the protective cover 62 to move.

[0038] Working principle: During use, the specimen to be tested is placed on the placement platform 2. The electric cylinder 61 drives the protective cover 62 at one end to move downwards and cover the specimen. Then, the hydraulic component 5 pressurizes the specimen. The hydraulic cylinder 51 drives the pressure block 52 at one end to move, and the pressure block 52 of the hydraulic component 5 pressurizes the specimen until the specimen is broken. The concrete fragments generated when the specimen breaks are intercepted by the protective cover 62 to prevent debris from flying. The pressure sensor of the hydraulic component 5 monitors the pressure in real time, records the maximum bearing capacity and calculates the strength to realize the strength test of the precast concrete component. After the test is completed, the hydraulic component 5 and the protective component 6 move upwards and reset. Then, the cleaning component 7 cleans the debris. The motor 72 drives the scraper 76 to move. During the movement of the scraper 76, the upper surface of the base 1 and the placement platform 2 is cleaned, and the debris is concentrated and driven into the slag hopper 8 to prepare for the next test.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
