Abstract
Description
Technical Field
[0001] The utility model belongs to the field of concrete detection, in particular to a concrete hardness detection device. Background Art
[0002] Concrete is widely used in construction projects, but in building structures, the hardness of concrete is particularly important. Only by ensuring the hardness of concrete can the firmness of the building structure be guaranteed, thereby extending the service life of the building structure. Therefore, several concrete blocks will be poured before use, and then the hardness testing device will be used to test the hardness of the concrete blocks one by one and analyze the data.
[0003] Most existing hardness testing devices can only test one concrete block at a time, and the efficiency of the entire test is low. In order to improve the efficiency of the test, there are now some hardness testing devices that are equipped with a rotating table, and a number of test seats are set on the rotating table, and the concrete blocks are placed in the test seats one by one. By switching different test seats by rotating the rotating table, the hardness testing mechanism can continuously test multiple concrete blocks. However, if a concrete block is missed or insufficiently placed in any of the test seats, the hardness testing mechanism will still work, which will cause the final data to be inaccurate. Utility Model Content
[0004] In view of the above problems, the purpose of the present utility model is to provide a concrete hardness detection device, aiming to solve the problem that the existing concrete hardness detection device has low detection efficiency and inaccurate detection data.
[0005] The utility model adopts the following technical solutions:

[0007] Furthermore, a conical pressure head is provided at the bottom of the pressure column.
[0008] Furthermore, the diameter of the pressure rod is greater than the diameter of the pressure column.
[0009] Furthermore, the carrier is provided with a plurality of guide blocks along the height direction, each guide block is provided with a guide opening, and the pressure rod passes through all the guide openings.
[0010] Furthermore, distance sensors are arranged inwardly at both left and right ends of the linear motor.
[0011] The beneficial effect of the utility model is that when the device is used to detect the hardness of concrete blocks, the concrete blocks are first placed one by one in the detection seat, and then the rotating table rotates one station, the station frame is located at the identification station, and the station camera is used to take pictures to identify whether there are concrete blocks in the current detection seat, and then the pressure sensor is driven and pressed down by the detection cylinder, and the pressure rod presses down the pressure column until the pressure head crushes the concrete block. If there is no concrete block in the current detection seat, the rotating table continues to rotate one station. In this way, the device can be used to continuously perform hardness tests on multiple concrete blocks, and at the same time, it can also avoid the situation where the concrete blocks are missed or insufficiently placed in the detection seat and affect the entire detection data.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0018] Combination Figure 1-3As shown, the hardness detection device includes a machine table 1, and the machine table 1 is respectively provided with a rotating table 3 and a hardness detection mechanism, and the hardness detection mechanism is arranged toward the rotating table, and the hardness detection mechanism includes a stand 2, and a carrier 4 is provided on the stand 1, and a detection cylinder 5 and a linear motor 6 are respectively provided at the upper and lower positions of the carrier 4, and a work station frame 7 is provided on the driving end of the linear motor 6, and a pair of mounting blocks 8 arranged up and down are provided on the work station frame 7, and a pressure column 9 is inserted into the same pair of mounting blocks 8, and a stopper 10 is formed between the two mounting blocks on the pressure column 9, and matching springs 11 are provided between the stopper 10 and the lower mounting block on the pressure column 9, and a pressure sensor 12 is provided on the driving shaft of the detection cylinder 5, and a pressure rod 13 is connected to the bottom of the pressure sensor 12, and a conical pressure head 15 is provided at the bottom of the pressure column 9, and a work station camera 14 is also provided on the work station frame 7
[0019] During the construction phase, it is usually necessary to sample and test the concrete used, such as testing the hardness of the concrete. At this time, the concrete is poured into the corresponding mold for casting and molding, and then the hardness of the molded concrete block is tested by a hardness testing device.
[0020] A plurality of detection seats 18 are arranged on the rotating platform 3 along the circumferential direction.
[0021] When using this device to detect the hardness of concrete blocks, first place the concrete blocks one by one in the detection seat, then the rotating table rotates one station, the station frame is located at the identification station, the station camera corresponds to the current detection seat up and down, and the station camera takes pictures to identify whether there is a concrete block in the current detection seat. If there is a concrete block, the linear motor drives the station frame to move horizontally and switch to the detection station, and then the detection cylinder drives and presses down the pressure sensor, and the pressure rod presses down the pressure column until the pressure head crushes the concrete block. At this time, the spring is compressed. The pressure sensor is externally connected to a detector, and at this time the pressure sensor senses and transmits the pressure signal to the detector.
[0022] If there is no concrete block in the current test seat, the rotating table continues to rotate one station until there is a concrete block in the test seat. In this way, the device can be used to continuously test the hardness of multiple concrete blocks, and it can also avoid the situation where the concrete block is missed or insufficient in the test seat and affects the entire test data.
[0023] When the hardness test of the concrete block is completed, the pressure rod is reset by the driving of the testing cylinder, and the spring recovers its deformation. Under the action of the spring, the pressure column is reset and waits for the next concrete block to be tested.
[0024] The diameter of the pressure rod is larger than the diameter of the pressure column, so that during the testing process, the pressure rod presses down and pushes the pressure column to move downward, making the entire hardness testing process more stable.
[0025] As a preferred structure, Figure 2 The carrier 4 is provided with a plurality of guide blocks 16 along the height direction, each of which has a guide opening, and the pressure rod 13 passes through all the guide openings. The guide blocks guide and limit the pressure rod through the guide openings, and under the action of the guide blocks, the entire hardness testing process can be further stabilized.
[0026] And as Figure 1-2 , the left and right ends of the linear motor 6 are both provided with distance sensors 17 facing inward. By providing distance sensors inward at the left and right ends of the linear motor, the station frame can be more accurate when switching stations through the distance sensors.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
