[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model provides a road cement test block testing device, such as... Figure 1-4 As shown, the road cement test block testing device includes: a mounting frame 1, on which a placement plate 2 for placing road cement test blocks to be tested is provided; a hydraulic rod 3 fixedly installed on the mounting frame 1, and a pressing block 4 for squeezing the road cement test blocks placed on the placement plate 2 is fixedly installed on the output shaft of the hydraulic rod 3; and a cleaning mechanism assembled on the mounting frame 1 and the placement plate 2 for cleaning the crushed road cement test blocks and residues on the placement plate 2.

[0023] In this embodiment, a controller of model OMRON E5CC-QX2ASM-800 is first installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. A pressure sensor of model HBM C6A is installed on the pressure block 4. When performing compressive strength testing on the road cement test block, the road cement test block to be tested is placed on the placement plate 2 on the mounting frame 1. The controller starts the hydraulic rod 3. The output shaft of the hydraulic rod 3 drives the pressure block 4 to squeeze the road cement test block placed on the placement plate 2 until the road cement test block is crushed. The pressure sensor detects the pressure on the road cement test block, thereby completing the test of the road cement test block's compressive strength. After the test is completed, the controller starts the unloading mechanism to drive the placement plate 2 to tilt and reverse at a certain angle, thereby cleaning the crushed road cement test block and residue on the placement plate 2, which facilitates the staff to test the next road cement test block and provides convenience for the staff.

[0024] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a servo motor 5 fixedly installed on the outer wall of one side of the mounting frame 1; a mounting shaft 6 rotatably installed on the mounting frame 1, wherein the output shaft of the servo motor 5 is connected to one end of the mounting shaft 6 through a coupling, and the mounting shaft 6 is fixedly connected to the placement plate 2.

[0025] In this embodiment, when cleaning the crushed road cement test blocks and residues remaining on the placement plate 2, the servo motor 5 is started by the controller. The output shaft of the servo motor 5 drives the mounting shaft 6, which is rotated on the mounting frame 1, through the coupling. Since the mounting shaft 6 and the placement plate 2 are fixedly connected, the rotation of the mounting shaft 6 will cause the placement plate 2 to rotate and tilt at a certain angle, thereby dumping the crushed road cement test blocks and residues on the placement plate 2, completing the cleaning work. This makes it convenient for staff to test different road cement test blocks and provides convenience for staff.

[0026] In a further preferred embodiment of the present invention, the mounting frame 1 is provided with a support mechanism for supporting the bottom of the placement plate 2. The support mechanism includes: a telescopic rod 7 fixedly installed in the storage cavity of the mounting frame 1; and a support plate 8 fixedly installed on the output shaft of the telescopic rod 7. The support plate 8 is used to support the bottom of the placement plate 2.

[0027] In this embodiment, during normal testing, the telescopic rod 7, which is fixedly installed in the storage cavity of the mounting frame 1, is in a suitable state. The support plate 8 on its output shaft provides contact support to the bottom of the placement plate 2, ensuring the stability of the placement plate 2 when it is subjected to the pressure of the road cement test block by the pressure block 4. When it is necessary to start the cleaning mechanism to drive the placement plate 2 to rotate for residue cleaning, the telescopic rod 7 is started by the controller to drive the support plate 8 to move down and detach from the bottom of the placement plate 2, thereby facilitating the tilting and unloading of the placement plate 2.

[0028] In a further preferred embodiment of this utility model, a limiting mechanism is provided on the placement plate 2. The limiting mechanism is used to limit the road cement test block placed on the placement plate 2. The limiting mechanism includes: a mounting block 9 fixedly installed on the placement plate 2; a screw rod 10 threadedly installed on the mounting block 9, and a positioning block 11 fixedly installed on the screw rod 10. The positioning block 11 is used to abut and limit the road cement test block placed on the placement plate 2.

[0029] In this embodiment, after the road cement test block is placed on the placement plate 2, the operator can manually rotate the screw 10 threaded onto the mounting block 9. Since the screw 10 is threadedly connected to the mounting block 9, as the screw 10 rotates, it will drive the positioning block 11 fixedly installed on it to move towards the road cement test block until the positioning block 11 contacts the road cement test block, thereby limiting the road cement test block placed on the placement plate 2, preventing the road cement test block from shifting during the testing process, and improving the stability of the road cement test block testing process. When cleaning the residue after the test, the screw 10 can be rotated in the opposite direction to move the positioning block 11 away from the road cement test block, making it convenient for the cleaning mechanism to perform cleaning operations. The limiting mechanism can be set in the front, back, left, and right of the placement plate 2 according to actual needs.

[0030] In a further preferred embodiment of the present invention, a guide hopper 12 is fixedly installed on the mounting frame 1. The guide hopper 12 is used to guide the waste generated during the testing of road cement test blocks. A receiving box 13 is provided on one side of the mounting frame 1. The receiving box 13 is located below the guide hopper 12 and is used to collect the waste generated during the testing of road cement test blocks.

[0031] In this embodiment, when the cleaning mechanism drives the placement plate 2 to rotate and dumps the crushed road cement test block and residue, the waste will fall into the guide hopper 12. The guide hopper 12, with its specific shape and installation position, guides the waste, causing it to slide down along the guide hopper 12 into the receiving box 13 below, thereby completing the collection of waste.

[0032] In a further preferred embodiment of the present invention, the mounting frame 1 and the pressure block 4 are provided with a guide mechanism for guiding the movement of the pressure block 4. The guide mechanism includes: a guide frame 14 fixedly mounted on the pressure block 4; and a guide rod 15 fixedly mounted on the mounting frame 1, wherein the guide rod 15 and the guide frame 14 are slidably connected.

[0033] In this embodiment, when the hydraulic rod 3 drives the pressure block 4 to perform compression testing on the road cement test block on the placement plate 2, the guide frame 14 fixedly installed on the pressure block 4 will slide along the guide rod 15 fixedly installed on the mounting frame 1. Through the sliding connection between the guide frame 14 and the guide rod 15, the pressure block 4 is guided to move stably in the vertical direction, ensuring that the pressure block 4 can accurately apply pressure to the road cement test block.

[0034] In a further preferred embodiment of the present invention, a protective door 16 is hinged to the mounting frame 1. The protective door 16 is made of transparent glass and is used to intercept and block debris generated during the testing of road cement test blocks.

[0035] In this embodiment, before testing the road cement test block, the staff closes the protective door 16. When the hydraulic rod 3 drives the pressure block 4 to squeeze the road cement test block on the placement plate 2, if the test block is crushed and produces debris, the protective door 16 will intercept and block it, preventing the debris from splashing out of the testing area. At the same time, since the protective door 16 is made of transparent glass, the staff can clearly observe the situation in the testing area through the protective door 16 during the testing process, including the pressure on the test block and the movement of the pressure block 4. After the test is completed, the staff opens the protective door 16 to carry out subsequent operations.

[0036] In a further preferred embodiment of the present invention, the guide hopper 12 is connected to the receiving cavity, the guide hopper 12 is used to guide the waste material in the receiving cavity, and the bottom of the receiving cavity is inclined.

[0037] In this embodiment, after the cleaning mechanism drives the placement plate 2 to rotate and dumps the crushed road cement test block and residue into the collection cavity, the waste will slide along the inclined bottom of the collection cavity under its own gravity to the guide hopper 12. The guide hopper 12 guides the waste sliding out of the collection cavity, so that the waste slides down the guide hopper 12 into the receiving box 13 located below it, thereby completing the collection of waste.

[0038] In summary, compared with related technologies, this device can perform compressive strength qualification testing on road cement test blocks, and facilitates the cleaning of waste generated during the testing process, making it convenient for staff to test different road cement test blocks and providing convenience for staff.
