Description

Technical Field

[0001] The invention belongs to the technical field of concrete detection devices, in particular to a testing device for detecting the quality of concrete vibration. Background Art

[0002] Concrete is a heterogeneous, brittle material formed by mixing sand and gravel aggregate, cement, water, and other additives. With the advancement of science and technology and the needs of the times, concrete structures have rapidly evolved, becoming the mainstream form of building structure and increasingly demonstrating their importance. The quality of concrete engineering directly impacts the safety of life and property, as well as the durability of building products. Therefore, quality defects in concrete structures are common and difficult to control, and are a direct cause of concrete quality problems.

[0003] Before concrete is poured and formed, it needs to be vibrated to make it denser and improve the strength of the concrete structure. Generally, a special test bench is required when testing concrete to ensure the accuracy of the experimental results and the controllability of the experimental process. When testing the strength of concrete, general test benches usually use dense quality detection tools. Manual operation of this tool can only be inserted from the upper surface of the concrete. Because the strength of concrete is different, the insertion depth is also limited. Therefore, the detected experimental data has certain limitations and needs to be improved. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention solves the technical problems thereof by adopting the following technical solutions: a test device for concrete vibration quality detection, comprising a main cylinder shell, the outer surface of the main cylinder shell is provided with a sliding sleeve shell, the lower part of the inner wall of the sliding sleeve shell is slidably connected to the upper part of the outer surface of the main cylinder shell, the lower surface of the main cylinder shell is fixedly connected to a shock-absorbing bottom shell, the interior of the main cylinder shell is provided with a plastic inner shell, the bottom end of the plastic inner shell is fixedly connected to the lower part of the inner wall of the main cylinder shell, the number of the plastic inner shells is two, and the The upper part of the outer surface of the shaped inner shell is clamped with a sealing cover; the main shaft rod, the bottom end of which is fixedly connected to a median partition, the lower surface of the median partition is fixedly connected to the lower part of the inner wall of the main cylinder shell, and the front and rear sides of the inner wall of the median partition are fixedly connected to the detection shell through a clamping groove; the detection shell includes a hardness detection plate, and the left and right sides of the outer surface of the hardness detection plate are symmetrically provided with arc-shaped sliding tubes, and the inner wall of the arc-shaped sliding tube is slidably connected to a cone-shaped arc rod on the side away from the hardness detection plate, and the front of the outer surface of the cone-shaped arc rod The top of the rotating connecting rod is fixedly connected to an external shift block, and the bottom of the rotating connecting rod is slidably connected to a side shaft rod. When performing a strength test of concrete, the operator shifts the external shift block 55 outside the device. At this time, the external shift block 55 pushes the rotating connecting rod 54 to slide toward the side of the shaping inner shell 4. Since the adapter shell 41 and the sealing cover 11 are pulled out together, the scale sockets on the front and rear sides of the shaping inner shell 4 are opened, so the rotating connecting rod 54 slides toward the shaping inner shell 4. During the rotation of the inner shell 4, the inner wall of the rotating connecting rod 54 pulls the conical arc rod 53 into the scale socket of the shaped inner shell 4, and then the pointed end of the conical arc rod 53 penetrates into the interior of the concrete from the side. During this process, the top end of the conical arc rod 53 will be subjected to the reaction force of the concrete, and the pressure gauge at the top end of the conical arc rod 53 will transmit the data to the hardness detection plate 51 through the internal wire, so that the hardness detection plate 51 will always display the measured pressure indication, and then judge the actual strength of the concrete under different conditions.

[0005] Preferably, the shaping inner shell includes an adaptor plug shell, and the lower part of the inner wall of the shaping inner shell is slidably connected with a movable bottom plate, and connecting spring belts are symmetrically provided on the front and rear sides of the lower part of the outer surface of the movable bottom plate, and vibration motors are symmetrically provided on the left and right sides of the outer surface of the movable bottom plate, and the outer surface of the vibration motor output shaft is fixedly connected with a rotating plate, and a frequency measuring shell is symmetrically provided on the front and rear sides of the lower part of the inner wall of the movable bottom plate. When using the device to test the strength of concrete, the main cylinder shell 1 and the sealing cover 11 are first opened. Since the device has two sets of shaping inner shells 4, a control experiment is carried out. After the interior of the shaping inner shell 4 is filled with cement, the sealing cover 11 is sealed, and the shaping inner shell 4 directly below is heated by the heating rod on the inner wall of the sliding shell 3, and the cement is waited for to solidify into concrete. Then the main cylinder shell 1 and the sealing cover 11 are opened again for detection. Since the scale socket on the side of the shaping inner shell 4 is blocked by the adaptor plug shell 41 during the cooling process of the cement, the cement can be cooled into concrete solid inside the shaping inner shell 4 without overflowing.

[0006] The top of the dotting timer 63 is fixedly connected to the display screen on the side of the shock-absorbing bottom shell 2 through a connecting wire. The side slide rail 62 is used to guide the cylindrical push rod 61 to slide in a directional manner so as to squeeze each other with the top button of the dotting timer 63. After the top of the dotting timer 63 is squeezed and punched by the side of the cylindrical push rod 61, the cylindrical push rod 61 will be pushed back to its original position by the internal elastic force. After the test is completed, the block concrete needs to be taken out from the inside of the adapter shell. At this time, the vibration motors on both sides of the movable bottom plate are started, and the vibration motors control the rotation of the rotating plate. When the rotating plate rotates to a vertical state, the top of the rotating plate will push the movable bottom plate upward, and then the movable bottom plate moves left and right. The spring belts connected on both sides drop and reset under the action of their own gravity. As the rotating plate rotates continuously, the upper surface of the movable bottom plate will perform high-frequency impact on the bottom of the concrete block inside the shaping inner shell. Under the impact of the movable bottom plate and the vibration of the shaping inner shell, the concrete block will quickly fall off from the inner wall of the shaping inner shell. At this time, the concrete block can be easily taken out. After simple cleaning, the test can be carried out again. When using the device to detect the strength of concrete, because the concrete is shaped inside the shaping inner shell, the hardness of the concrete can be tested at different time states during this process. Moreover, when using the cone-headed arc rod to test the hardness of concrete, the operator moves the external block on the outside to directly avoid contact with the internal concrete solid, thereby maintaining the block structure of the concrete. At the same time, the operator can accurately control the penetration depth of the cone-headed arc rod through the moving distance of the external block, thereby detecting the strength of the concrete solid at different depths.

[0007] Preferably, scale sockets are symmetrically provided on the front and rear sides of the outer surface of the shaping inner shell, and the scale sockets extend to the inner wall of the shaping inner shell, the lower surface of the sealing cover is fixedly connected to the upper surface of the adapter socket, and the upper surface of the sealing cover is fixedly connected to an auxiliary handle. Since the concrete will be fixed inside the shaping inner shell after solidification during testing, the concrete is difficult to remove at this time, and the movable bottom plate at the bottom of the shaping inner shell of the device is not fixedly connected to the shaping inner shell. In the process of removing the concrete, the top of the rotating plate periodically pushes the movable bottom plate to move upward, and the upper surface of the movable bottom plate will perform high-frequency impact on the bottom of the concrete block inside the shaping inner shell. Under the impact of the movable bottom plate and the vibration of the shaping inner shell, the concrete block will quickly fall off from the inner wall of the shaping inner shell. At this time, the concrete block can be easily removed, and after simple cleaning, the test work can be carried out again.

[0008] Preferably, the top end of the cone-shaped arc rod extends to the inside of the plastic inner shell through the scale socket, the diameter of the top of the outer surface of the cone-shaped arc rod is the same as the diameter of the inner wall of the scale socket, the pressure measuring end at the top end of the cone-shaped arc rod is fixedly connected to the inner wall of the hardness testing plate through a connecting wire, and the side of the main cylinder shell is evenly provided with through grooves, and the side of the rotating connecting rod is slidably connected to the inner wall of the main cylinder shell through the through grooves. The detection shell of the device is provided with multiple groups of cone-shaped arc rods, so the device can perform targeted measurements on positions of different depths and different levels of concrete blocks, and the sockets of the plastic inner shell are all on the same vertical plane, so the position of each cone-shaped arc rod inserted into the concrete is roughly the same, with only a deviation in height, so the strength testing of positions at different depths of concrete is more comparative, and under the guidance of the rotating connecting rod and the plastic inner shell, the position of the cone-shaped arc rod insertion is fixed, so the accuracy is very high and it will not cause serious damage to the concrete block.

[0009] Preferably, the frequency measuring housing includes a cylindrical push rod, the front and rear ends of the cylindrical push rod are rotatably connected to the side support rods, and the outer surface of the side support rod is slidably connected to the side slide rail, the middle part of the inner wall of the side slide rail is fixedly connected to the dotting timer, and the bottom end of the dotting timer is fixedly connected to the display screen on the side of the shock-absorbing bottom shell through a connecting wire. When the rotating plate rotates, the top of the rotating plate will sweep the concave surface of the frequency measuring housing, and at this time the top of the rotating plate will push the cylindrical push rod to slide toward the inner wall of the frequency measuring housing. The cylindrical push rod will reduce the friction between the top of the rotating plate and the cylindrical push rod by rotating itself to ensure that the top of the rotating plate can pass through the frequency measuring housing smoothly. In the process of the cylindrical push rod sliding toward the inner wall of the frequency measuring housing, the support rod on the side of the cylindrical push rod will slide along the side slide rail toward the top of the dotting timer and collide with the top of the dotting timer. At this time, the top of the dotting timer is subjected to the impact force and performs a single dotting operation. Then the cylindrical push rod is pushed back to its original position by the dotting timer, waiting for the next contact with the top of the rotating plate.

[0010] The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structure of said sliding panel also is provided with an interlocking structure. The interlocking structure of said sliding panel also is provided with an interlocking structure.

[0011] Preferably, the number of the independent pipe sleeves 71 is five, and the axis center of the inner wall of the independent pipe sleeve 71 is fixedly connected to the outer surface of the side shaft 7, and the upper and lower sides of the inner wall of the independent pipe sleeve 71 are symmetrically provided with arc-shaped grooves, and the upper and lower sides of the outer surface of the arc-shaped slider 73 are slidably connected to the inner wall of the independent pipe sleeve 71 through the arc-shaped grooves, one end of the inner spring belt 74 is fixedly connected to the outer surface of the arc-shaped slider 73, and the other end of the inner spring belt 74 is fixedly connected to the outer surface of the fixed link 72, and the sliding sleeve includes a threaded pipe sleeve, and the inner wall of the threaded pipe sleeve is threadedly connected to a rotating link, and the upper part of the inner wall of the sliding sleeve is symmetrically provided with a heating rod, and the heating rod The upper surface of the main cylinder shell is symmetrically provided with a spring sleeve, and the end of the heating rod close to the rotating connecting rod is slidably connected to the bottom end of the rotating connecting rod through a cluster tube sleeve. After the sliding sleeve is sleeved on the upper surface of the main cylinder shell, the heating rods on the left and right sides start to work, heating or cooling the plastic inner shell directly below, so that the concrete blocks inside the plastic inner shell are cooled to different degrees. When the rotating connecting rod is rotated clockwise, the rotating connecting rod spirally slides down along the inner wall of the threaded tube sleeve, and then pushes the heating rods on the left and right sides downward through the cluster rod at the bottom. At this time, the spring sleeve above the heating rod is stretched, and the heating rod is closer to the plastic inner shell, and the effect on the temperature of the cement blocks inside the plastic inner shell is more obvious.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The detection shell of the device is equipped with multiple groups of cone-shaped arc rods, so the device can perform targeted measurements on positions of different depths and different levels of concrete blocks, and the sockets of the shaping inner shell are all on the same vertical plane, so the position where each cone-shaped arc rod penetrates the concrete is roughly the same, with only the height deviation. Therefore, the strength test of positions at different depths of concrete is more comparative, and under the guidance of the rotating connecting rod and the shaping inner shell, the position of the cone-shaped arc rod is fixed, so the accuracy is very high and it will not cause serious damage to the concrete block.

[0014] 2. When using the device to detect the strength of concrete, because the concrete is shaped inside the shaping inner shell, the hardness of the concrete can be tested at different time states during this process. Moreover, when using the cone-headed arc rod to test the hardness of the concrete, the operator moves the external block on the outside to directly avoid contact with the internal concrete solid, thereby maintaining the block structure of the concrete. At the same time, the operator can accurately control the penetration depth of the cone-headed arc rod through the moving distance of the external block, thereby detecting the strength of the concrete solid at different depths.

[0015] 3. Since the concrete will be fixed inside the shaping inner shell after solidification during testing, it is difficult to remove the concrete at this time. The movable bottom plate at the bottom of the shaping inner shell of the device is not fixedly connected to the shaping inner shell. In the process of removing the concrete, the top of the rotating plate periodically pushes the movable bottom plate to move upward, and the upper surface of the movable bottom plate will perform high-frequency impact on the bottom of the concrete block inside the shaping inner shell. Under the impact of the movable bottom plate and the vibration of the shaping inner shell, the concrete block will quickly fall off from the inner wall of the shaping inner shell. At this time, the concrete block can be easily removed, and after simple cleaning, the test can be carried out again.

[0016] 4. The device detects the rotation speed of the rotating plate in real time through the frequency measuring shell at the bottom, and then controls the rotation speed of the vibration motor according to the actual quality of the concrete, to prevent the problem that the vibration motor speed is too low, resulting in poor vibration effect of the movable bottom plate on the heavier concrete, and the vibration motor speed is too high, resulting in the lighter concrete flying out of the inside of the shaping inner shell. In addition, the device can move the heating rod closer to the shaping inner shell by rotating the connecting rod, so that the temperature of the cement block inside the shaping inner shell is more significantly affected.

[0017] 5. During the rotation of the rotating connecting rod, the bottom end of the rotating connecting rod pulls the arc-shaped slider to slide in the sliding grooves on the upper and lower sides of the inner wall of the independent pipe sleeve. During this process, the inner spring belts on the corresponding sides of the rotating connecting rod are deformed, so that the rotating connecting rod can automatically reset after the operator releases the external shift block. Due to the independence of the arc-shaped slider, when the rotating connecting rod on one side is rotated, the rotating connecting rod on the other side will not be affected by force due to the isolation effect of the fixed connecting rod, thereby ensuring the accuracy of the detection results of each cone head arc rod.

[0030] The detection housing 5 includes a hardness detection plate 51. Arc-shaped slide tubes 52 are symmetrically provided on the left and right sides of the outer surface of the hardness detection plate 51. A conical arc-shaped rod 53 is slidably connected to the inner wall of the arc-shaped slide tube 52 away from the hardness detection plate 51. A rotating connecting rod 54 is fixedly connected to the front of the outer surface of the conical arc-shaped rod 53. The top end of the rotating connecting rod 54 is fixedly connected to an external shift block 55. The bottom end of the rotating connecting rod 54 is slidably connected to the side shaft rod 7.

[0031] The shaping inner shell 4 includes an adapting plug-in shell 41, and the lower part of the inner wall of the shaping inner shell 4 is slidably connected to a movable bottom plate 42. Connecting spring belts 45 are symmetrically arranged on the front and rear sides of the lower part of the outer surface of the movable bottom plate 42. Vibration motors 43 are symmetrically arranged on the left and right sides of the outer surface of the movable bottom plate 42. The outer surface of the output shaft of the vibration motor 43 is fixedly connected to a rotating plate 44. The frequency measuring shell 6 is symmetrically arranged on the front and rear sides of the lower part of the inner wall of the movable bottom plate 42.

[0032] Vertical slide grooves are symmetrically provided on the left and right sides of the inner wall of the movable bottom plate 42. The outer surface of the output shaft of the vibration motor 43 is slidingly connected to the inner wall of the movable bottom plate 42 through the vertical slide grooves. The bottom end of the vibration motor 43 is fixedly connected to the side of the inner wall of the shock-absorbing bottom shell 2. The top end of the rotating plate 44 is slidingly connected to the inner wall of the movable bottom plate 42. The top end of the connecting spring belt 45 is fixedly connected to the lower surface of the shaping inner shell 4.

[0033] Scale sockets are symmetrically opened on the front and back sides of the outer surface of the shaped inner shell 4, and the scale sockets extend to the inner wall of the shaped inner shell 4. The lower surface of the sealing cover 11 is fixedly connected to the upper surface of the adapter shell 41, and the upper surface of the sealing cover 11 is fixedly connected to an auxiliary handle.

[0034] The top end of the conical arc rod 53 extends to the interior of the plastic inner shell 4 through the scale socket. The diameter of the top of the outer surface of the conical arc rod 53 is the same as the diameter of the inner wall of the scale socket. The pressure measuring end at the top end of the conical arc rod 53 is fixedly connected to the inner wall of the hardness testing plate 51 through a connecting wire. The side of the main cylinder shell 1 is evenly provided with through grooves, and the side of the rotating connecting rod 54 is slidably connected to the inner wall of the main cylinder shell 1 through the through grooves.

[0035] When using the device to test the strength of concrete, first open the main cylinder shell 1 and the sealing cover 11. Since the device has two sets of shaping inner shells 4, a control experiment is carried out. After filling the interior of the shaping inner shell 4 with cement, the sealing cover 11 is sealed, and the shaping inner shell 4 directly below is heated by the heating rod on the inner wall of the sliding sleeve 3. Wait for the cement to solidify into concrete, and then open the main cylinder shell 1 and the sealing cover 11 again to carry out the detection work. Since the scale socket on the side of the shaping inner shell 4 is blocked by the adapter plug shell 41 during the cooling process of the cement, the cement can be cooled into concrete solid inside the shaping inner shell 4 without overflowing.

[0036] When conducting a strength test of concrete, the operator shifts the external shift block 55 on the outside of the device. At this time, the external shift block 55 pushes the rotating connecting rod 54 to slide toward the side close to the shaping inner shell 4. Since the adapter shell 41 and the sealing cover 11 are pulled out together, the scale sockets on the front and rear sides of the shaping inner shell 4 are opened. Therefore, in the process of rotating the rotating connecting rod 54 toward the shaping inner shell 4, the inner wall of the rotating connecting rod 54 pulls the conical head arc rod 53 into the scale socket of the shaping inner shell 4, and then the pointed end of the conical head arc rod 53 penetrates into the interior of the concrete from the side. During this process, the top end of the conical head arc rod 53 will be subjected to the reaction force of the concrete, and the top pressure gauge of the conical head arc rod 53 will transmit the data to the hardness test plate 51 through the internal wire, so that the hardness test plate 51 always displays the measured pressure indication, thereby judging the actual strength of the concrete in different states.

[0037] After the test is completed, the concrete block needs to be taken out from the inside of the shaping inner shell 4. At this time, the vibration motors 43 on both sides of the movable bottom plate 42 are started. The vibration motors 43 control the rotation of the rotating plate 44. When the rotating plate 44 rotates to a vertical state, the top of the rotating plate 44 will push the movable bottom plate 42 upward. Then the movable bottom plate 42 drops and resets under the action of the spring belts 45 connected on the left and right sides and its own gravity. As the rotating plate 44 continues to rotate, the upper surface of the movable bottom plate 42 will perform high-frequency impact on the bottom of the concrete block inside the shaping inner shell 4. Under the impact of the movable bottom plate 42 and the vibration of the shaping inner shell 4, the concrete block will soon fall off from the inner wall of the shaping inner shell 4. At this time, the concrete block can be easily taken out. After simple cleaning, the test can be carried out again.

[0048] There are five independent pipe sleeves 71. The axis center of the inner wall of the independent pipe sleeve 71 is fixedly connected to the outer surface of the side shaft 7. Arc-shaped rotation grooves are symmetrically opened on the upper and lower sides of the inner wall of the independent pipe sleeve 71. The upper and lower sides of the outer surface of the arc-shaped slider 73 are slidingly connected to the inner wall of the independent pipe sleeve 71 through the arc-shaped rotation groove. One end of the inner spring belt 74 is fixedly connected to the outer surface of the arc-shaped slider 73, and the other end of the inner spring belt 74 is fixedly connected to the outer surface of the fixed connecting rod 72.

[0049] The sliding housing 3 includes a threaded sleeve 31, the inner wall of which is threadedly connected to a rotating connecting rod 32, a heating rod 33 is symmetrically arranged on the upper part of the inner wall of the sliding housing 3, and a spring sleeve 34 is symmetrically arranged on the upper surface of the heating rod 33, and the end of the heating rod 33 close to the rotating connecting rod 32 is squeezed against the bottom end of the rotating connecting rod 32 through the cluster sleeve.

[0050] When the rotating plate 44 rotates, the top of the rotating plate 44 will sweep across the concave surface of the frequency measuring housing 6. At this time, the top of the rotating plate 44 will push the cylindrical push rod 61 to slide toward the inner wall of the frequency measuring housing 6. At this time, the cylindrical push rod 61 will reduce the friction generated by the top of the rotating plate 44 and the cylindrical push rod 61 by self-rotation to ensure that the top of the rotating plate 44 can smoothly pass through the frequency measuring housing 6. In the process of the cylindrical push rod 61 sliding toward the inner wall of the frequency measuring housing 6, the support rod on the side of the cylindrical push rod 61 will slide along the side slide rail 62 toward the top of the dotting timer 63 and collide with the top of the dotting timer 63. At this time, the top of the dotting timer 63 is subjected to the impact force and performs a single dotting operation. Then the cylindrical push rod 61 is pushed back to its original position by the dotting timer 63, waiting for the next contact with the top of the rotating plate 44.

[0051] During the process of rotating the rotating connecting rod 54, the bottom end of the rotating connecting rod 54 pulls the arc-shaped slider 73 to slide in the sliding grooves on the upper and lower sides of the inner wall of the independent pipe sleeve 71. During this process, the inner spring belts 74 on the corresponding sides of the rotating connecting rod 54 are deformed, so that the rotating connecting rod 54 can automatically reset after the operator releases the external shift block 55. Due to the independence of the arc-shaped slider 73, when the rotating connecting rod 54 on one side is rotated, the rotating connecting rod 54 on the other side will not be affected by force due to the isolation effect of the fixed connecting rod 72, thereby ensuring the accuracy of the detection results of each cone head arc rod 53.

[0052] After the sliding sleeve 3 is sleeved on the upper surface of the main cylinder shell 1, the heating rods 33 on the left and right sides start to work, heating or cooling the shaping inner shell 4 directly below, so that the concrete blocks inside the shaping inner shell 4 are cooled to varying degrees. When the rotating connecting rod 32 is rotated clockwise, the rotating connecting rod 32 spirals down along the inner wall of the threaded sleeve 31, and then pushes the heating rods 33 on the left and right sides downward through the bundling rod at the bottom. At this time, the spring sleeve 34 above the heating rod 33 is stretched, and the heating rod 33 is closer to the shaping inner shell 4, and the effect on the temperature of the cement blocks inside the shaping inner shell 4 is more obvious.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
