Description

Technical Field

[0001] The present invention relates to the technical field of temperature-controlled ice flexural performance testing, and more particularly to a temperature-controlled ice flexural performance testing device and method thereof. Background Art

[0002] Flexural strength is an important performance index of materials, which determines the bearing capacity and seismic resistance of structures. Measuring the flexural performance of materials is of great significance for evaluating the safety and stability of structures. At present, in material mechanics, the three-point bending method is usually used to measure the flexural performance of materials and has been widely used in civil engineering. However, at present, these devices do not have independent loading capabilities and temperature control technologies, and need to rely on external testing machines to provide bending loads. This greatly limits on-site material performance testing and is not portable. For ice and frozen soil materials in cold regions, temperature changes and transportation disturbances during the transfer from the site to the laboratory will cause great measurement errors.

[0003] During the use of existing devices, different materials need to be detected. During the temperature-controlled ice flexural performance test of some materials with relatively high density, the operator needs to spend a lot of effort to place the materials on the test device. Therefore, it is not convenient for users to use. Moreover, during the testing process, some materials may break and splash during the application of pressure, which may cause damage to the temperature control box. Therefore, it is not convenient for safe detection. Summary of the Invention

[0009] Furthermore, the sealing assembly includes a positioning top plate. A first guide wheel is installed in the middle of the bottom of the positioning top plate.

First rubber telescopic cloths are fixedly connected to both sides of the bottom of the positioning top plate. A mountain-shaped positioning plate is fixedly connected to the bottom of the first rubber telescopic cloth.

[0010] Furthermore, the dimensions of the connecting and supporting leg assembly and the dimensions outside the lifting base have a tolerance fit, and the lifting base and the connecting and supporting leg assembly are welded.

[0013] A temperature-controlled ice flexural strength test method includes the following steps:

[0014] S1. Material placement and positioning: Place the material to be tested for temperature-controlled ice flexural strength onto the tops of the roller assemblies on the left and right through transportation or hoisting equipment, and then push the material to be tested for temperature-controlled ice flexural strength towards the middle of the positioning assembly. During the movement of the material, the rotation of the roller body reduces the frictional force during the movement of the material, effectively reducing the force required to push the material, thus facilitating the use by the user.

[0015] S2. Material testing: During the test, rotate the loading wheel disc to make the loading piston extend or retract, thereby pushing the movable crossbeam downward, and then driving the upper support pin downward. Through the cooperation between the upper support pin and the lower support pin, the temperature-controlled ice flexural strength test is achieved. At the same time, pull the pull rope, and under the positioning of the first guide wheel and the second guide wheel, pull the second rubber telescopic cloth to unfold through the pull positioning block. Then, drive the mountain-shaped positioning plate to rise or fall through the movable crossbeam, and then drive the first rubber telescopic cloth to unfold, thereby isolating the test environment of the material for temperature-controlled ice flexural strength test, effectively protecting the inside of the temperature measurement box located outside the connecting support leg assembly, avoiding damage to the temperature measurement box caused by the splashing of the material for temperature-controlled ice flexural strength test due to pressure, and ensuring the normal operation of the equipment.

[0016] During the detection, first rotate the rotating arm to drive the support block away from the roller assembly. During the detection process of the upper support pin and the lower support pin, under the action of pressure, if the material deforms, it will cause the positioning return plate to descend, thereby pushing the lifting return plate and the lifting limit plate to descend, and then compressing the telescopic spring. Moreover, the height of the lifting return plate can be detected by setting a sensor, thereby calculating the test result and enabling secondary verification of the test result.

[0017] S3. The device moves. During the process of device movement, rotating the rotating arm and the support block drives the threaded rod to rotate. Subsequently, due to the cooperation between the hexagonal lifting block and the hexagonal positioning groove, the hexagonal lifting block is pushed downward, causing the device to rise. Then, the roller assembly is separated from the positioning assembly, and the roller assembly is flipped to insert the positioning slider into the sliding groove. The roller body can then be used as a moving wheel. Then, through the cooperation among the lifting loop plate, the lifting limit plate, the telescopic spring, and the lifting base, it can be used as a shock-absorbing assembly for the moving wheel, facilitating the movement of the device.

[0018] Technical effects and advantages of the present invention:

[0019] 1. In the present invention, the material to be tested for the temperature-controlled ice flexural strength is placed on the top of the roller assemblies on the left and right sides through transportation or hoisting equipment. Then, the material to be tested for the temperature-controlled ice flexural strength is pushed towards the middle of the positioning assembly. During the movement of the material, the rotation of the roller body reduces the friction force during the movement of the material, effectively reducing the force required to push the material, thus facilitating the use by the user.

[0020] 2. During the test of the present invention, the loading piston is extended or shortened by rotating the loading wheel disc, thereby pushing the movable crossbeam downward. Subsequently, the upper support pin is driven downward, and the temperature-controlled ice flexural strength test is achieved through the cooperation between the upper support pin and the lower support pin. At the same time, the pulling rope is pulled, and under the positioning of the first guide wheel and the second guide wheel, the second rubber telescopic cloth is unfolded by pulling the positioning block. Then, the movable crossbeam drives the mountain-shaped positioning plate to rise or fall, and then drives the first rubber telescopic cloth to unfold, thereby isolating the test environment of the material for the temperature-controlled ice flexural strength test, effectively protecting the interior of the temperature measurement box located outside the connecting support leg assembly, avoiding damage to the temperature measurement box caused by the splashing of the material due to pressure during the temperature-controlled ice flexural strength test, and ensuring the normal operation of the device.

[0021] 3. When conducting the detection of the present invention, first rotate the rotating arm to drive the support block away from the roller assembly. During the detection process of the upper support pin and the lower support pin, under the action of pressure, if the material deforms, the positioning loop plate will descend, thereby pushing the lifting loop plate and the lifting limit plate downward. Subsequently, the telescopic spring is compressed, and the height of the lifting loop plate can be detected by setting a sensor, thereby calculating the test result and enabling secondary verification of the test result.

[0022] 4. During the process of moving the device of the present invention, the rotation of the rotating arm and the support block drives the rotation of the threaded rod. Subsequently, due to the cooperation between the hexagonal lifting block and the hexagonal positioning groove, the hexagonal lifting block is pushed to move downward, thereby raising the device. Then, the roller assembly is separated from the positioning assembly, and the roller assembly is flipped to insert the positioning slider into the sliding groove. The roller body can be used as a moving wheel. Then, through the cooperation among the lifting U-shaped plate, the lifting limit plate, the telescopic spring, and the lifting base, it can be used as a shock-absorbing assembly for the moving wheel, thus facilitating the movement of the device.

During the movement of the material, the rotation of the roller body 1037 reduces the frictional force received during the movement of the material, effectively reducing the force required to push the material, thus facilitating the user's operation.

[0034] Further, the positioning component 101 includes a positioning base 1011. A positioning square groove 1012 is opened in the middle of the top of the positioning base 1011. U-shaped positioning grooves 1013 are opened on both sides of the positioning base 1011. Sliding grooves 1014 are opened on the front and back of the U-shaped positioning grooves 1013. Hexagonal positioning grooves 1015 are opened at the four corners of the top of the positioning base 1011.

[0035] Further, the connecting support leg assembly 102 includes a support leg main body 1021. A reinforcing inclined plate 1022 is installed on one side of the support leg main body 1021 close to the roller assembly 103.

A threaded rod 1026 is installed at the bottom of the rotating shaft 1025. A hexagonal lifting block 1027 is sleeved on the outer side of the threaded rod 1026. A rotating arm 1028 is fixedly connected to the outer side of the rotating shaft 1025. A support block 1029 is installed on one side of the rotating arm 1028 away from the rotating shaft 1025. A positioning notch 10210 is formed at the top of the side of the support block 1029 close to the roller assembly 103. During the process of moving the equipment, by rotating the rotating arm 1028 and the support block 1029 to drive the threaded rod 1026 to rotate, then due to the cooperation between the hexagonal lifting block 1027 and the hexagonal positioning groove 1015, the hexagonal lifting block 1027 will be pushed to move downward, and then the equipment will be lifted. Then, the roller assembly 103 is separated from the positioning assembly 101, and then the roller assembly 103 is flipped to insert the positioning slider 1032 into the sliding groove 1014. The roller main body 1037 can be used as a moving wheel. Then, through the cooperation among the lifting return plate 1035, the lifting limit plate 1033, the telescopic spring 1034 and the lifting base 1031, it can be used as a shock absorption assembly of the moving wheel, thus facilitating the movement of the equipment.

[0036] Further, the roller assembly 103 includes a lifting base 1031. Positioning sliders 1032 are fixedly connected to the front and back sides of the lifting base 1031 close to the positioning assembly 101.

A roller main body 1037 is installed inside the positioning return plate 1036. During the inspection, first rotate the rotating arm 1028 to drive the support block 1029 away from the roller assembly 103. During the inspection of the upper support pin 5 and the lower support pin 104, under the action of pressure, if the material deforms, the positioning return plate 1036 will descend, thus pushing the lifting return plate 1035 and the lifting limit plate 1033 to descend, and then the telescopic spring 1034 will be compressed. And the height of the lifting return plate 1035 can be detected by setting a sensor, so as to calculate the test result and be able to verify the test result twice.

[0037] Furthermore, the sealing assembly 2 includes a positioning top plate 201. In the middle of the bottom of the positioning top plate 201, a first guiding wheel 202 is installed.

Through the cooperation between the upper stud 5 and the lower stud 104, the temperature-controlled ice flexural strength performance test is realized. At the same time, the pulling rope 206 is pulled to drive the second rubber telescopic cloth 208 to unfold under the positioning of the first guiding wheel 202 and the second guiding wheels 205 through the pulling positioning block 207. Then, the mountain-shaped positioning plate 204 is driven to rise or fall by the movable crossbeam 4, and then drive the first rubber telescopic cloth 203 to unfold, so as to isolate the test environment of the temperature-controlled ice flexural strength performance test material, effectively protecting the inside of the temperature measuring box located outside the connecting support leg assembly 102, avoiding the damage of the temperature measuring box caused by the splashing of the temperature-controlled ice flexural strength performance test material due to pressure, and ensuring the normal operation of the equipment.

[0038] Furthermore, the dimensional tolerance between the size of the connecting support leg assembly 102 and the outer size of the lifting base 1031 is coordinated, and the lifting base 1031 and the connecting support leg assembly 102 are welded. When the roller assembly 103 is located inside the connecting support leg assembly 102, the positioning slider 1032 is not provided. The width of the U-shaped positioning groove 1013 and the width of the lifting base 1031 have a clearance fit, and the shape and size of the sliding groove 1014 and the shape and size of the positioning slider 1032 have a clearance fit.

A threaded groove is opened at the top of the hexagonal lifting block 1027, and the thread on the outer side of the hexagonal lifting block 1027 and the thread on the top of the threaded rod 1026 cooperate with each other.

[0040] Furthermore, both the front and back sides of the first rubber telescopic cloth 203 are attached to the main body 1021 of the support leg. Both sides of the second rubber telescopic cloth 208 are attached to the main body 1021 of the support leg. A positioning groove is provided inside the side wall of the lifting base 1031. The size inside the positioning groove of the lifting base 1031 has a clearance fit with the cross-sectional size of the lifting limit plate 1033. The opening size at the top of the positioning groove of the lifting base 1031 has a clearance fit with the size of the lifting return plate 1035.

[0041] A temperature-controlled ice flexural performance test method includes the following steps:

[0042] S1. Material placement and positioning: Place the material to be tested for temperature-controlled ice flexural performance on the top of the roller assemblies 103 on the left and right through transportation or hoisting equipment. Then, push the material to be tested for temperature-controlled ice flexural performance towards the middle of the positioning assembly 101. During the movement of the material, the rotation of the roller body 1037 reduces the friction force during the movement of the material, effectively reducing the force required to push the material, thus facilitating the use by the user.

[0043] S2. Material testing: During the test, rotate the loading wheel disc 7 to extend or shorten the loading piston 3, thereby pushing the movable crossbeam 4 downward, and then driving the upper support pin 5 downward. The temperature-controlled ice flexural performance test is achieved through the cooperation between the upper support pin 5 and the lower support pin 104. At the same time, pull a pulling rope 206 to pull the second rubber telescopic cloth 208 to unfold under the positioning of the first guide wheel 202 and the second guide wheel 205. Then, drive the mountain-shaped positioning plate 204 to rise or fall through the movable crossbeam 4, and then drive the first rubber telescopic cloth 203 to unfold, thereby isolating the test environment of the material for temperature-controlled ice flexural performance test, effectively protecting the inside of the temperature measurement box located outside the connecting support leg assembly 102, and avoiding damage to the temperature measurement box caused by the splashing of the material for temperature-controlled ice flexural performance test due to pressure, ensuring the normal operation of the equipment.

[0044] During the detection, first rotate the rotating arm 1028 to drive the support block 1029 away from the roller assembly 103. During the detection process of the upper support pin 5 and the lower support pin 104, under the action of pressure, if the material deforms, it will cause the positioning return plate 1036 to descend, thereby pushing the lifting return plate 1035 and the lifting limit plate 1033 to descend, and then compressing the telescopic spring 1034. The height of the lifting return plate 1035 can be detected by setting a sensor, thereby calculating the test result and enabling secondary verification of the test result.

[0045] S3. The device moves. During the process of device movement, the rotation of the rotating arm 1028 and the support block 1029 drives the rotation of the threaded rod 1026. Subsequently, due to the cooperation between the hexagonal lifting block 1027 and the hexagonal positioning groove 1015, the hexagonal lifting block 1027 is pushed to move downward, and then the device is lifted. Then, the roller assembly 103 is separated from the positioning assembly 101, and then the roller assembly 103 is flipped to insert the positioning slider 1032 into the sliding groove 1014. The roller body 1037 can be used as a moving wheel. Then, through the cooperation among the lifting return plate 1035, the lifting limit plate 1033, the telescopic spring 1034, and the lifting base 1031, it can be used as a shock absorption assembly of the moving wheel, thus facilitating the movement of the device.

8. A method for testing the anti-bending performance of temperature-controlled ice, using a device for testing the anti-bending performance of temperature-controlled ice according to claim 7, characterized in that: The following steps are involved: S1. Material placement and positioning: the material to be tested for temperature-controlled ice bending resistance is placed on the top of the roller assemblies (103) on the left and right sides by means of transportation or lifting equipment, and then the material to be tested for temperature-controlled ice bending resistance is pushed toward the middle of the positioning assembly (101). During the movement of the material, the roller body (1037) rotates to reduce the friction force on the material during the movement, thereby effectively reducing the force for pushing the material to move, thereby facilitating use by the user; S2, material testing, when the test is performed, the loading wheel (7) is rotated to extend or shorten the loading piston (3), thereby pushing the movable crossbeam (4) down, and then driving the upper support nail (5) down, and realizing the temperature control ice anti-bending performance test through the cooperation between the upper support nail (5) and the lower support nail (104), and at the same time, a pulling rope (206) is pulled to pull the second rubber telescopic cloth (208) to unfold by pulling the positioning block (207) under the positioning of the first guide wheel (202) and the second guide wheel (205), and then the mountain-shaped positioning plate (204) is driven to rise or fall through the movable crossbeam (4), and then the first rubber telescopic cloth (203) is driven to unfold, thereby isolating the test environment of the temperature control ice anti-bending performance test material, effectively protecting the inside of the temperature measuring box located outside the connecting support leg assembly (102), avoiding the temperature control ice anti-bending performance test material from splashing due to pressure, and thus preventing the temperature measuring box from being damaged, thereby ensuring the normal operation of the equipment; When testing, the rotating arm (1028) is first rotated to drive the support block (1029) away from the roller assembly (103). During the testing process of the upper support nail (5) and the lower support nail (104), if the material is deformed under the action of pressure, the positioning return plate (1036) will be lowered, thereby pushing the lifting return plate (1035) and the lifting limit plate (1033) to fall, and then the telescopic spring (1034) will be compressed. A sensor can be set to detect the height of the lifting return plate (1035), thereby calculating the test result, and the test result can be verified twice. S3, equipment movement. When the equipment needs to be moved, the threaded rod (1026) is driven to rotate by rotating the rotating arm (1028) and the support block (1029). Then, due to the cooperation between the hexagonal lifting block (1027) and the hexagonal positioning groove (1015), the hexagonal lifting block (1027) is pushed to move toward the bottom, thereby raising the equipment. Then, by separating the roller assembly (103) from the positioning assembly (101), and then reversing the roller assembly (103) to insert the positioning slider (1032) into the sliding groove (1014), the roller body (1037) can be used as a moving wheel. Then, through the cooperation between the lifting return plate (1035), the lifting limit plate (1033), the telescopic spring (1034) and the lifting base (1031), it can be used as a shock absorbing component of the moving wheel, thereby facilitating the movement of the equipment.
