Description

Technical Field

[0001] This utility model relates to the technical field of cleaning devices for universal testing machines, and specifically to a cleaning device for a universal testing machine. Background Technology

[0002] Concrete, due to its readily available raw materials, convenient preparation, good plasticity, and strong stability, has become one of the most widely used civil engineering materials today. With the rapid development of infrastructure, concrete is widely used in highways, water conservancy and hydropower projects, and building construction. In the engineering design and construction process of concrete, its mechanical properties are particularly important. Concrete compressive strength is a crucial indicator of concrete quality. Its principle is that the aggregates and fine aggregates in concrete, under external force, can withstand a certain pressure and continuously deform until final failure. Current standards typically use a universal testing machine to determine the compressive strength of concrete. However, the following problems exist in conducting concrete compressive strength tests: After each test, crushed specimen fragments often remain on the testing equipment. The space between the moving beam and the test base of the equipment is small, making it difficult for personnel to clean the specimen fragments during the test. The presence of specimen fragments on the bearing plate affects the accuracy of subsequent tests.

[0003] Therefore, the development of a cleaning device for universal testing machines has significant engineering application value, as it is difficult to clean the residual specimen debris on the pressure plate of the universal testing machine after testing. Utility Model Content

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a cleaning device for a universal testing machine, which is used for cleaning the universal testing machine, especially for concrete compressive strength testing. It can effectively clean the specimen debris on the pressure plate of the universal testing machine after the test, while preventing the specimen debris from splashing and improving the test accuracy. It is a cleaning device with convenient structure and simple operation.

[0026] refer to Figures 1-6 This utility model provides a cleaning device for a universal testing machine, including: a cleaning device, a debris collection device 1, and a transmission device;

[0027] The cleaning device includes an iron enclosure 5, a brush 2, and nuts 4. The brush 2 is connected to the bottom of the iron enclosure 5, and nuts 4 are welded or glued to both sides of the iron enclosure 5. Nuts 4 are installed horizontally on each side to ensure that the drive shaft 3 can be inserted. Each nut 4 is equipped with a transmission device; the transmission device includes a motor 7, a coupling 6, and a drive shaft 3; the output end of the motor 7 is connected to the drive shaft 3 through the coupling 6, and the drive shaft 3 passes through the nut 4, forming a ball screw structure with the nut 4. Specifically, the iron enclosure 5 is a U-shaped enclosure made of sheet metal. The size of the iron enclosure 5 is larger than the size of the specimen. It is set on the pressure plate of the universal testing machine to protect the outer perimeter of the pressure plate. During the test, the iron enclosure 5 can prevent specimen fragments from splashing. The two ends of the drive shaft 3 on each side are rotatably mounted in the support column on one side of the pressure plate of the universal testing machine. Therefore, the motor 7 drives the drive shaft 3 to rotate through the coupling 6. Through the ball screw structure, the rotational motion of the drive shaft 3 is converted into the horizontal movement of the cleaning device, which cleans the residual specimen debris on the pressure plate of the universal testing machine through the brush 2. Depending on the density of the specimen, the brush 2 is selected as either a bristle brush or a wire brush; if the density of the specimen is too high, a bristle brush may not be effective enough, and a wire brush may be used. The coupling 6 connects the motor 7 and the drive shaft 3, and also prevents the connected parts from bearing excessive load, thus providing overload protection. The motor 7 is a power device that can rotate in both forward and reverse directions, thereby realizing the horizontal reciprocating movement of the cleaning device.

[0028] The debris collection device 1 is located below the cleaning device. The debris collection device 1 is made of sheet metal and is wider than the cleaning device. It is located below the pressure plate of the universal testing machine and is used to collect the specimen debris swept off the pressure plate by the cleaning device.

[0029] The present invention provides a cleaning device for a universal testing machine, the usage method of which is as follows:

[0030] S01: First, set the cleaning device consisting of iron enclosure 5, brush 2 and nut 4 between the pressure plate and moving crossbeam of the universal testing machine, install the transmission device, connect the motor 7 to the power supply, and set the debris collection device 1 below the universal testing machine.

[0031] S02: Next, the test block is placed on the pressure plate for relevant tests. During the test, the iron enclosure 5 protects against the splashing of fragments from the test piece.

[0032] After the test is completed, the incompletely broken test block is taken out, the motor 7 is started, the motor 7 drives the transmission shaft 3 to rotate through the coupling 6, which in turn drives the iron enclosure 5 and brush 2 of the cleaning device to move back and forth horizontally to clean the fragments of the test piece on the pressure plate.

[0033] S03: When the cleaning device moves horizontally back and forth, the debris generated during the test will fall into the debris collection device 1.

[0034] S04: When the cleaning device moves to a certain position, the motor 7 rotates in the opposite direction, and the iron enclosure 5 and brush 2 of the cleaning device return to their initial positions. The next set of tests can then be carried out.

[0035] This invention provides a cleaning device for a universal testing machine. A motor drives a transmission shaft, enabling the cleaning device to move horizontally back and forth, allowing the brush connected to the device to clean test debris from the pressure plate of the universal testing machine. The cleaning device includes an iron enclosure, solving the problems of specimen debris splashing during testing, difficulty in cleaning, low testing efficiency, and reduced testing accuracy in existing universal testing machines.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
