Description

Technical Field

[0001] The utility model relates to the technical field of concrete pressure test, and particularly relates to a concrete pressure test device. Background Technique

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone prepared by mixing cementitious materials, granular aggregates, water, and, if necessary, admixtures and additives in a certain proportion, uniformly stirred, densely formed, and cured and hardened.

[0003] In the existing test device, there is no mechanism for fixing concrete blocks inside. Therefore, during the test, when the concrete blocks are subjected to pressure, they are likely to move, which affects the test results. Now, a concrete pressure test device is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a concrete pressure test device to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A concrete pressure test device includes a measuring mechanism. A fixing mechanism is fixedly connected to the upper surface of the measuring mechanism, and a dust suction mechanism is fixedly connected to the measuring mechanism.

[0007] The fixing mechanism includes a feeding box. Support grooves are symmetrically opened on both sides of the feeding box. A T-shaped support rod is movably connected in the support grooves of the feeding box. Positioning holes are opened on both the T-shaped support rod and the feeding box, and a positioning rod is movably connected inside the positioning holes.

[0008] A further improvement of the technical solution of the utility model is that one end of the T-shaped support rod is fixedly connected with a support plate. A spring is fixedly connected to the back of the support plate, and one end of the spring is fixedly connected to the inner wall of the feeding box. When the pressure on the spring disappears, it drives the support plate to move towards the middle, reducing the distance between the two support plates, thereby fixing the concrete block.

[0009] A further improvement of the technical solution of the utility model is that the measuring mechanism includes a base. A pressure sensor is arranged on the base, and the pressure sensor is fixedly connected to the bottom of the feeding box. The pressure received by the concrete is recorded by the pressure sensor, which is convenient for storing test data.

[0010] A further improvement of the technical solution of the present utility model lies in that: a transmitter is electrically connected to the pressure sensor, a display screen is electrically connected to the transmitter, both the transmitter and the display screen are fixedly connected to the base, a support frame is fixedly connected to the upper surface of the base, and the transmitter transmits the data in the pressure sensor into the display screen, facilitating the tester to observe the data.

[0011] A further improvement of the technical solution of the present utility model lies in that: the dust suction mechanism includes a blower, an air outlet is arranged at the back of the blower, a filter screen is arranged at the air suction port of the blower, a dust storage box is fixedly connected to the air suction port of the blower, and the filter screen can block concrete debris to prevent it from entering the interior of the blower.

[0012] A further improvement of the technical solution of the present utility model lies in that: a dust suction pipe is fixedly connected to the dust storage box, one end of the dust suction pipe is fixedly connected to a dust-proof cover, a cylinder is fixedly connected to the interior of the dust-proof cover, and an output end of the cylinder is fixedly connected to a pressing block. When the cylinder operates, it can drive the pressing block to move downward, thereby pressing the concrete block.

[0013] A further improvement of the technical solution of the present utility model lies in that: the blower, the dust storage box and the cylinder are all fixedly connected to the support frame, and the dust-proof cover is located above the feeding box. Since the dust-proof cover is located above the feeding box, when the concrete block cracks, it can block the debris and prevent the debris from harming the operator.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0015] 1. The present utility model provides a concrete pressure test device. Push the two support plates outward, then place the concrete block between the two support plates, release the support plates, the pressure on the spring disappears, drive the support plates to move towards the middle, reduce the distance between the two support plates, make both support plates adhere to the concrete block, insert the positioning rod into the two positioning holes to fix the position of the T-shaped support rod, thereby fixing the position of the support plate, improving the fixing strength of the concrete block, and further avoiding the phenomenon of the concrete block moving during the test, improving the accuracy of the test result.

The fixing mechanism 1 includes a feeding box 11. Support grooves are symmetrically formed on both sides of the feeding box 11. A T-shaped support rod 12 is movably connected in the support grooves of the feeding box 11. Positioning holes 13 are formed on both the T-shaped support rod 12 and the feeding box 11. A positioning rod 14 is movably connected inside the positioning holes 13. One end of the T-shaped support rod 12 is fixedly connected with a support plate 15, and a spring 16 is fixedly connected to the back of the support plate 15. One end of the spring 16 is fixedly connected to the inner wall of the feeding box 11;

[0025] Specifically, push the two support plates 15 outward, then place the concrete block between the two support plates 15, release the support plates 15, the pressure received by the spring 16 disappears, drive the support plates 15 to move towards the middle, reduce the distance between the two support plates 15, so that both support plates 15 are in contact with the concrete block, insert the positioning rod 14 into the two positioning holes 13 to fix the position of the T-shaped support rod 12, thereby fixing the position of the support plate 15, improving the fixing strength of the concrete block, and further avoiding the phenomenon of the concrete block moving during the test, improving the accuracy of the test result.

[0026] Embodiment 2

[0027] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the measuring mechanism 2 includes a base 21, a pressure sensor 22 is arranged on the base 21, the pressure sensor 22 is fixedly connected to the bottom of the feeding box 11, a transmitter 23 is electrically connected to the pressure sensor 22, a display screen 24 is electrically connected to the transmitter 23, both the transmitter 23 and the display screen 24 are fixedly connected to the base 21, and a support frame 25 is fixedly connected to the upper surface of the base 21;

[0028] Specifically, the pressure sensor 22 is connected to the feeding box 11, so it is necessary to manually zero-set the weight of the feeding box 11 and its internal structure on the pressure sensor 22. The pressing block 36 is driven by the cylinder 35 to move downward to press the concrete. The pressure received by the pressure sensor 22 during pressing is transmitted into the display screen 24 through the transmitter 23, so that the bearing pressure curve graph of the concrete block can be obtained during the whole pressing process, which is convenient for the operator to collect data.

[0029] Embodiment 3

[0030] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the dust suction mechanism 3 includes a fan 31, an air outlet is arranged on the back of the fan 31, a filter screen is arranged at the air suction port of the fan 31, a dust storage box 32 is fixedly connected to the air suction port of the fan 31, a dust suction pipe 33 is fixedly connected to the dust storage box 32, one end of the dust suction pipe 33 is fixedly connected to a dust-proof cover 34, a cylinder 35 is fixedly connected to the inside of the dust-proof cover 34, the output end of the cylinder 35 is fixedly connected to a pressing block 36, the fan 31, the dust storage box 32 and the cylinder 35 are all fixedly connected to the support frame 25, and the dust-proof cover 34 is located above the feeding box 11;

[0031] Specifically, after the concrete block is fixed, the cylinder 35 is started to drive the pressing block 36 to move downward to press the concrete block. When the concrete block breaks, the pressure received by the pressure sensor 22 is zeroed, so that the maximum pressure borne by the concrete block can be determined. During the whole process of pressing the concrete block, the dust-proof cover 34 is located above the feeding box 11, so that when the concrete block cracks, the debris can be blocked to avoid the debris from hurting the operator, and at the same time, the splashing range of the concrete block is reduced.

[0032] The working principle of the concrete pressure test device will be specifically described below.

Start the cylinder 35 to drive the pressing block 36 to move downward to press the concrete block. When the concrete block breaks, the pressure received by the pressure sensor 22 is cleared to zero. During the whole pressing process, the transmitter 23 transmits the data into the display screen 24, so that the bearing pressure curve graph of the concrete block can be obtained, which is convenient for the operator to collect the data. When the concrete block cracks, the dust-proof cover 34 blocks the debris and reduces the splashing range of the concrete block. Start the fan 31, and suck the debris in the feeding box 11 through the dust storage box 32 and the dust suction pipe 33, so that it enters the dust storage box 32 to clean the feeding box 11.
