Description

Technical Field

[0001] This utility model relates to the field of pressure testing machine technology, specifically a portable pressure testing machine for testing the strength of cement clinker. Background Technology

[0002] In the quality control process of cement production, cement clinker strength testing is a key step in ensuring the quality of cement products. Generally, cement clinker is first ground together with an appropriate amount of gypsum to make cement, and then specimens of specific shapes such as prisms and cubes are made. Compressive strength, flexural strength, and other properties are then tested using precision testing instruments such as pressure testing machines.

[0003] In actual strength testing operations, the placement of the specimen has varying degrees of impact on the testing environment and subsequent cleanup. When a specimen is placed on a standard platform for pressure testing, the lack of effective shielding around the platform results in a large amount of debris and dust being generated upon the specimen's breakage. This debris can scatter in all directions, causing physical damage to testing equipment such as the pressure testing machine, affecting its accuracy and lifespan, and also scattering throughout the testing space, increasing the difficulty and workload of cleanup. To improve this situation, some testing scenarios employ placing the specimen in a recessed space. This recessed space can, to some extent, prevent the splashing of debris and the spread of dust, providing a degree of protection. However, because the recessed space is usually quite deep, after the specimen breaks, debris and dust tend to accumulate at the bottom and corners of the recessed space, making effective cleanup difficult. The cleanup process often requires a significant amount of time and effort, and may even require specialized tools and equipment, which not only reduces the efficiency of the testing work but also increases testing costs.

[0004] Therefore, this utility model provides a portable pressure testing machine for testing the strength of cement clinker. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a portable pressure testing machine for testing the strength of cement clinker, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable pressure testing machine for testing the strength of cement clinker, comprising a base and a protective sleeve. A lifting plate is installed inside the protective sleeve, and an L-shaped vertical support is installed on one side of the base. The lifting plate is slidably connected to the inner wall of the protective sleeve. A PVC mesh sleeve is installed at the top of the lifting plate and can be fitted over the outside of the protective sleeve. An outer ring is installed at one end of the PVC mesh sleeve and is slidably connected to the inner wall of the protective sleeve. A top plate is rotatably connected to the top of the L-shaped vertical support. A pressure telescopic rod for testing the specimen is installed on the top plate. A pressure plate that contacts the specimen is installed at the bottom of the pressure telescopic rod. The pressure telescopic rod is perpendicularly aligned with the protective sleeve. The pressure plate is inserted into the protective sleeve. A handle is installed on one side of the L-shaped vertical support.

[0007] Preferably, a clearance hole is provided on one side of the L-shaped vertical bracket, and a screw is rotatably connected to the inner wall of the clearance hole. A micro motor corresponding to the position of the screw is installed inside the L-shaped vertical bracket, and a cross connector is fixedly connected to one side of the outer ring.

[0011] Beneficial effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) This utility model achieves two layers of outer protection for cement clinker specimens by using a protective sleeve and a PVC mesh cover, so that when the specimen breaks, the fragments will not fly everywhere, reducing the difficulty and workload of subsequent cleaning.

[0014] (2) By using the lifting plate, PVC mesh sleeve and outer ring together, the specimen will not directly contact the protective sleeve.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A portable pressure testing machine for testing the strength of cement clinker includes a base 1 and a protective sleeve 11. A lifting plate 2 is installed inside the protective sleeve 11, and an L-shaped vertical support 3 is installed on one side of the base 1.

[0023] The lifting plate 2 is slidably connected to the inner wall of the protective sleeve 11. A PVC mesh sleeve 21 is installed at the top of the lifting plate 2. The PVC mesh sleeve 21 can be fitted onto the outside of the protective sleeve 11. An outer ring 22 is installed at one end of the PVC mesh sleeve 21. The outer ring 22 is slidably connected to the inner wall of the protective sleeve 11.

[0024] It should be noted that the outer ring 22 described in this embodiment is in contact with the inner wall of the bottom side of the protective sleeve 11.

[0025] The top of the L-shaped vertical bracket 3 is rotatably connected to a top plate 31. A pressure telescopic rod 32 for testing the specimen is installed on the top plate 31. A pressure plate 33 that contacts the specimen is installed at the bottom of the pressure telescopic rod 32. The pressure telescopic rod 32 is perpendicularly aligned with the protective sleeve 11. The pressure plate 33 is inserted into the protective sleeve 11. A handle 34 is installed on one side of the L-shaped vertical bracket 3.

[0026] It should be noted that a pressure sensor is installed between the pressure telescopic rod 32 and the pressure plate 33 described in this embodiment.

[0027] Specifically, to address the issues of clinker specimens shattering and sputtering during testing, causing environmental pollution, and the difficulty of cleaning when placed in recessed spaces, this pressure testing machine utilizes a base 1 for bottom support. The internal space of the protective sleeve 11 stores the specimen. An L-shaped vertical bracket 3 supports the pressure telescopic rod 32 via a top plate 31. The pressure telescopic rod 32 increases the contact area with the specimen via a pressure plate 33, ensuring experimental effectiveness. The pressure plate 33 can enter the protective sleeve 11. The pressure plate 33 and the lifting plate 2 clamp the specimen vertically. When the specimen presses down on the lifting plate 2 to the inner bottom wall of the protective sleeve 11, the protective sleeve 11 limits the lifting plate 2, preventing it from descending further. The pressure telescopic rod 32 continues to apply thrust to the pressure plate 33, allowing it to compress the specimen. A pressure sensor between the pressure telescopic rod 32 and the pressure plate 33 detects the pressure value applied to the specimen by the pressure testing machine. The protective sleeve 11 can shield the specimen in case of breakage. The lifting plate 2 and PVC mesh fabric... The sleeve 21 wraps the inner space of the protective sleeve 11, preventing the specimen from directly contacting the protective sleeve 11 and preventing fragments from flying everywhere, thus reducing the difficulty and workload of subsequent cleaning. The lifting plate 2 slides up and down within the protective sleeve 11. The lifting plate 2 is constrained by the PVC mesh sleeve 21, and the outer ring 22 pulls and controls the PVC mesh sleeve 21. When the outer ring 22 slides towards the base 1, it can pull the PVC mesh sleeve 21 to slide out of the protective sleeve 11. The PVC mesh sleeve 21 lifts the lifting plate 2, raising it to the same height as the top of the protective sleeve 11. The inner wall of the PVC mesh sleeve 21, which was originally inside the protective sleeve 11, becomes the outer wall, and the lifting plate 2 is raised to the end position. At this time, both the lifting plate 2 and the PVC mesh sleeve 21 are easy for workers to clean, facilitating effective cleaning. The cleaning process is simple and convenient, requiring no significant time or effort, thus improving the efficiency of the testing work.

[0028] In one embodiment of this utility model, such as Figures 1-5 As shown, a clearance hole 35 is provided on one side of the L-shaped vertical bracket 3, and a screw 36 is rotatably connected to the inner wall of the clearance hole 35. A micro motor 361 corresponding to the position of the screw 36 is installed inside the L-shaped vertical bracket 3. A cross connector 23 is fixedly connected to one side of the outer ring 22, and the screw 36 is threaded to the inner wall of the cross connector 23.

[0029] It should be noted that the cross connector 23 described in this embodiment can contact the top of the base 1.

[0030] Specifically, the L-shaped vertical bracket 3 makes room for the cross connector 23 and the screw 36 through the clearance hole 35. The micro motor 361 drives the screw 36 to rotate. The screw 36 drives the cross connector 23 to adjust its up and down position, thereby adjusting the height of the lifting plate 2 inside the protective sleeve 11. When the lifting plate 2 is pulled to the highest position, the cross connector 23 drives the outer ring 22 to contact the top of the base 1. At this time, the cross connector 23 is in a low position, and there is also a gap between the L-shaped vertical bracket 3 and the PVC mesh cover 21, which facilitates the cleaning of the PVC mesh cover 21.

[0031] In one embodiment of this utility model, such as Figures 1-5 As shown, a limit bolt 311 is rotatably connected to the inner wall of the top plate 31, and the limit bolt 311 is threadedly connected to the top of the L-shaped vertical bracket 3.

[0032] It should be noted that the area where the sidewall of the limiting bolt 311 contacts the top plate 31 described in this embodiment is a smooth cylindrical shape.

[0033] Specifically, when the top plate 31 is installed with the L-shaped vertical bracket 3, the top plate 31 is mounted on the top of the L-shaped vertical bracket 3. The limiting bolt 311 is aligned with the screw hole on the top of the L-shaped vertical bracket 3 through the through hole on the top plate 31 and tightened. At this time, the limiting bolt 311 locks the top plate 31. The rotation of the top plate 31 on the top of the L-shaped vertical bracket 3 and the normal locking operation of the limiting bolt 311 will not affect each other. By rotating the top plate 31, the pressure plate 33 and the pressure telescopic rod 32 can be misaligned with the protective sleeve 11, which makes it easier to pick up and put down the lime clinker specimen.

[0034] In one embodiment of this utility model, such as Figures 1-5 As shown, the inner wall of the L-shaped vertical bracket 3 is slidably connected to a limiting rod 4, and the bottom end of the top plate 31 is provided with an insertion hole 312, into which the limiting rod 4 is inserted.

[0035] Specifically, when the top plate 31 drives the pressure telescopic rod 32 to rotate directly above the protective sleeve 11, the insertion hole 312 corresponds to the position of the limiting rod 4. By controlling the limiting rod 4 to rise, the limiting rod 4 can be inserted into the insertion hole 312, thereby completing the angular position locking of the top plate 31, the pressure telescopic rod 32 and the pressure plate 33.

[0036] In one embodiment of this utility model, such as Figures 1-5 As shown, a sliding groove 37 is provided on one side of the L-shaped vertical bracket 3, and a pull block 41 is installed at the bottom of the limiting rod 4. The pull block 41 is slidably connected to the inner wall of the sliding groove 37, and a return spring 42 for pushing the pull block 41 is installed on the inner wall of the sliding groove 37.

[0037] Specifically, the slide 37 accommodates the pull block 41 and the return spring 42, and the return spring 42 pushes the pull block 41 upward, so that the pull block 41 can drive the limit rod 4 to be stably inserted into the socket 312 for positioning.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Working principle: During use, rotating the top plate 31 causes the pressure plate 33 and pressure telescopic rod 32 to be misaligned with the protective sleeve 11, facilitating the placement of the lime clinker specimen into the internal space of the protective sleeve 11. Then, rotating the top plate 31 again positions the pressure plate 33 and pressure telescopic rod 32 directly above the protective sleeve 11. At this point, the insertion hole 312 corresponds to the position of the limiting insertion rod 4, which is slidably connected to the inner wall of the L-shaped vertical bracket 3. Due to the return spring 42 on the inner wall of the sliding groove 37 on one side of the L-shaped vertical bracket 3, the return spring 42 will... Pushing the pull block 41 at the bottom of the limiting rod 4 upwards allows the limiting rod 4 to be inserted into the insertion hole 312, locking the angle position of the top plate 31, the pressure telescopic rod 32, and the pressure plate 33. The specimen is placed inside the protective sleeve 11. The L-shaped vertical bracket 3 supports the pressure telescopic rod 32 through the top plate 31. The pressure plate 33 at the bottom of the pressure telescopic rod 32 increases the contact area with the specimen. The pressure plate 33 enters the protective sleeve 11, clamping the specimen vertically with the lifting plate 2. When the specimen is pressed down... When the lifting plate 2 reaches the inner wall of the bottom side of the protective sleeve 11, the protective sleeve 11 limits the lifting plate 2. The pressure telescopic rod 32 continues to apply a pushing force to the pressure plate 33 to squeeze the specimen. The pressure sensor between the pressure telescopic rod 32 and the pressure plate 33 detects the pressure value on the specimen. When the specimen breaks, the lifting plate 2 and the PVC mesh cloth sleeve 21 wrap around the internal space of the protective sleeve 11, so that the specimen does not directly contact the protective sleeve 11 and prevents fragments from flying everywhere. The lifting plate 2 slides up and down inside the protective sleeve 11, constrained by the PVC mesh cloth sleeve 21. The outer ring 22 can pull the PVC mesh cloth sleeve 21. When the outer ring 22 slides towards the base 1, it pulls the PVC mesh cloth sleeve 21 to slide out of the protective sleeve 11. The PVC mesh cloth sleeve 21 lifts the lifting plate 2 to the same height as the top of the protective sleeve 11. At this time, the inner wall of the lifting plate 2 and the PVC mesh cloth sleeve 21, which were originally inside the protective sleeve 11, becomes the outer wall, and the lifting plate 2 is at the end position, which is convenient for the staff to clean.
