Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to an electric cement bending machine with a protective structure. Background Technology

[0002] Cement is a key component of concrete, and its properties significantly impact concrete quality. For example, silicate cement has high early strength, making it suitable for projects requiring rapid demolding; while slag cement has better corrosion resistance, making it suitable for projects in corrosive environments. As one of the most commonly used materials in construction engineering, the quality of cement directly affects the structural safety and durability of buildings. To ensure that cement quality meets standard requirements, various properties of cement need to be tested, among which flexural strength is one of the important indicators for measuring cement's mechanical properties. Therefore, an electric cement flexural strength tester is needed to accurately and efficiently measure the flexural strength of cement.

[0003] In the process of realizing this utility model, the inventor discovered the following problems with the existing technology: 1. Ordinary electric cement bending testers do not have corresponding protective structures when conducting bending tests on materials. When the material breaks, the generated particles can pose a certain danger to the workers; 2. Ordinary electric cement bending testers generate some debris and particles when conducting bending tests on materials. When conducting subsequent tests, the workers need to manually clean them, which is time-consuming, labor-intensive, and reduces work efficiency. Utility Model Content

[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the bending and pressing assembly 7 includes connecting frames 702 mounted on both sides of the measuring ruler 601 via a second connecting rod 701. A first pull rod 703 is fixedly connected to one end of the connecting frame 702, a second connecting piece 704 is fixedly connected to one end of the first pull rod 703, a second pull rod 705 is fixedly connected to one end of the second connecting piece 704, and a third connecting piece 706 is fixedly connected to one end of the second pull rod 705.

A bending and pressing groove 709 is fixedly connected to one end of the connecting groove 708, and a bending and pressing rod 7010 is fixedly connected to the lower inner side of the bending and pressing groove 709. Through this design, the equipment can perform a bending and pressing process on the material through the interaction between the various components, ensuring that the material can be bent and pressed smoothly and effectively, so as to provide the staff with effective experimental data and ensure the effectiveness and accuracy of the bending resistance test.

[0039] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the protective cover 201 has a slot, the first connecting piece 204 and the telescopic rod 205 form a linkage structure, and the telescopic rod 205 and the protective cover 202 form a transmission structure. This design enables protection when conducting bending tests on materials, effectively ensuring that workers are not injured by particles generated during the experiment, thus increasing safety. At the same time, workers can open the protective cover 202, and it provides corresponding support when opening, ensuring that workers are not injured by falling objects when placing and picking up materials. It also ensures that the moving component 6 can move smoothly when the angle changes without touching the protective cover 201.

[0040] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the suction pipe 304, connecting pipe 303, and suction pump 302 form a linked structure. Sliding rods with the same shape as the bracket 305 are fixedly connected to both sides of the bottom of the dust collection tank 306. This design allows for simultaneous dust removal during the flexural strength test, ensuring effective cleaning and subsequent collection of dust and particulate matter generated during material breakage. This eliminates the need for staff to stop the test for cleaning, increasing the continuity of subsequent experiments. Furthermore, the dust collection tank 306 can be quickly pulled out for cleaning of collected dust and particulate matter, ensuring excellent dust removal performance.

[0041] In this embodiment, as Figure 1 , Figure 2 and Figure 6As shown, a groove is provided at the top center of the second fixing block 508, and the first spring 509 and the fixing rod 5010 form an elastic structure. Through this design, when the moving component 6 is unloaded after completing the bending resistance test of the material, the elastic deformation of the first spring 509 can provide a certain buffer, thereby ensuring that the equipment always maintains good stability and will not fall off. This increases stability and also increases safety.

[0042] In this embodiment, as Figure 1 , Figure 2 and Figure 7 As shown, the first motor 605 and the threaded rod 606 form a rotating structure, and the threaded rod 606 and the weight 6011 form a linkage structure. Through this design, the weight 6011 can continuously undergo displacement, thereby ensuring that the bending resistance test of the material can be carried out effectively. This allows the staff to record the position of the weight 6011 when the material breaks, thereby calculating the bending resistance data of the material and ensuring the validity and accuracy of the data.

[0043] In this embodiment, as Figure 1 , Figure 2 and Figure 9 As shown, the second motor 802 and the double-acting lead screw 803 form a rotating structure, the double-acting lead screw 803 and the threaded collar 804 form a linkage structure, the fourth connecting piece 805, the lifting rod 806 and the fifth connecting piece 807 form a linkage structure through the cooperation of the second motor 802 and the double-acting lead screw 803, and the second spring 8010 and the clamping plate 8011 form an elastic structure. Through this design, materials of different sizes can be clamped by the elastic deformation of the second spring 8010, so that the materials have good stability when undergoing bending resistance testing, and the materials can be lifted to the corresponding position and maintain good stability after being lifted to the corresponding position, thereby ensuring the accuracy of the test results.

[0044] The method of use and advantages of this utility model: The working process of this electric cement bending resistance machine with a protective structure is as follows:

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, firstly, by pulling handle 203, the protective cover 202 is opened. At this time, the telescopic rod 205 will extend and retract, thereby causing the first connecting piece 204 to change its angle. This allows the protective cover 202 to open while providing some support and fixation, preventing injury to workers. Materials can then be placed on the placement plate 808. The elastic deformation of the second spring 8010 causes the clamping plates 8011 on both sides to limit the material. The second motor 802 can then be activated, and its output shaft will drive the bidirectional lead screw 803 to rotate. This causes the threaded collars 804 on both sides to move in opposite directions. Simultaneously, the angle between the fourth connector 805, the lifting rod 806, and the fifth connector 807 changes, thus raising the placement plate 808. When it reaches the appropriate position, the second motor 802 is turned off, and the first motor 605 can be started to close the protective cover 202. The output shaft of the first motor 605 will drive the threaded rod 606 to rotate, causing the weight 6011 to move away from the first motor 605. During the movement of the weight 6011... In the process, the moving component 6 changes angle, and through the lever principle, the connecting frame 702 drives the first pull rod 703 to move vertically upward. At this time, the second connecting piece 704 changes angle, causing the second pull rod 705 to drive the third connecting piece 706 to change angle. This causes the bending groove 709 to drive the bending rod 7010 to bend and compress the material. When the material breaks, the operator can observe and record the corresponding data on the measuring ruler 601 through the observation window 207 for subsequent experimental data calculation. When the bending is completed, the second limit block 609... The material will touch the fixing rod 5010. Through the elastic deformation of the first spring 509, the fixing rod 5010 will slide in the groove of the second fixing block 508 to perform buffering work. While performing the bending and pressing work, the dust pump 302 can be turned on. The dust suction pipe 304 will absorb the dust and particulate matter generated when the material breaks. It will be sucked into the dust collection tank 306 in the dust collection box 301 through the connecting pipe 303 to collect the dust and particulate matter. The operator can pull the handle 308 to pull out the dust collection tank 306 for cleaning and to ensure the efficiency of subsequent collection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
