[0003] Currently, strength testing of cement pipes typically requires the use of a strength testing device. This device involves inserting the testing mechanism into the pipe body and using a rebound hammer mounted on the outside to test the strength of the cement pipe and check whether the inner diameter of the cement pipe meets quality requirements. However, existing cement pipes generally have circular grooves on their outer sides for pipe insertion. Since these grooves are not on the same horizontal plane, the position of the testing mechanism needs to be adjusted multiple times during measurement, resulting in a significant time consumption and inaccurate measurement data. Therefore, improvements are needed. Utility Model Content

Both sides of the output shaft of the second drive structure are threaded with movable blocks. A connecting plate is hinged to the outside of the movable block, and a movable frame is hinged to the other end of the connecting plate.

The baffle is elastically connected to the connecting column by a spring.
[0008] Preferably, a spring is sleeved on the outer surface of the connecting column, and the two sides of the spring are respectively connected to the connecting column and the connecting block.
[0009] Preferably, a moving block is movably connected to the outside of the rebound spring, the outside of the moving block is movably sleeved with the inner wall of the connecting block, and the moving block is connected to the rebound spring by a spring.
[0010] Preferably, a stop block is provided on the inner side of the baffle, and the inner side of the stop block extends into the inner cavity of the connecting block.
[0011] Preferably, the movable frame has a slot on its outer side, and a bolt is provided inside the slot, with the bottom of the bolt extending into the inner cavity of the connecting block.
[0012] Preferably, the outer side of the support rod is movably sleeved inside the adjustment mechanism, and a drive structure is provided on the outer side of the support rod.
[0013] Preferably, the material rack mechanism includes a rotating component, a disk is provided on the top of the rotating component, a drive component is provided inside the disk, and limit frames are threaded onto both sides of the output shaft of the drive component.
[0014] Preferably, the adjustment mechanism includes a second drive assembly and a connecting rod. The outer sides of both the second drive assembly and the connecting rod are connected to the inner wall of the base frame. The output shaft of the second drive assembly is threaded with a connecting frame, and the inner wall of the connecting frame is movably connected to the outer surface of the connecting rod.
[0015] Preferably, a pneumatic cylinder is provided at the top of the connecting frame, a mounting bracket is provided at the top of the pneumatic cylinder, the bottom of the mounting bracket extends into the inner cavity of the connecting frame, and the inner wall of the mounting bracket is movably connected to the outer side of the support rod.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model is equipped with a baffle and an inclined block. By activating the second drive structure, the positioning component is moved to the inside of the circular groove of the cement pipe. At this time, the adjustment mechanism pulls the entire movable frame outward. The baffle is squeezed by the circular groove, which drives the rebound hammer to move outward. At the same time, the inclined surface of the inclined block moves the rebound hammer out of the connecting block. Thus, by activating the second drive structure, the rebound hammer is squeezed onto the inner wall of the circular groove for strength testing. This makes it easier to test the strength of the circular groove opened on the cement pipe, eliminating the need to adjust the position of the rebound hammer multiple times and reducing the difficulty of testing.
[0018] This utility model is equipped with an inclined block and a pressure block. When performing strength testing on the circular groove opened on the outside of the cement pipe, the movable frame is moved to a certain distance from the circular groove, and the baffle is larger than the diameter of the circular groove. At this time, the baffle is blocked by the circular groove, which drives the connecting column and the pressure block to move outward. The pressure block passes through the inclined surface of the inclined block, and the rebound hammer moves out of the inner cavity of the connecting block. When the pressure block moves from the inclined surface to the horizontal part, the pressure block is vibrated by the horizontal part to prevent the rebound hammer from resetting. Since the circular groove opened on the outside of the cement pipe is not in the same horizontal position, the movable frame continues to move, so that the connecting blocks in other positions move the rebound hammer out through the inclined surface of the inclined block. The connecting blocks that have already moved out of the rebound hammer will continue to move on the horizontal part of the inclined block until all the rebound hammers are moved out of the connecting block. This makes it easy to keep the rebound hammer aligned with the circular groove during testing, so that multiple points can be tested simultaneously, thus improving the testing efficiency.
[0019] This utility model is equipped with connecting blocks and bolts. By rotating the bolts, the fixing of the connecting blocks is released, thereby adjusting the distance between the two sets of connecting blocks to be the same as the wall thickness plus inner diameter of the cement pipe to be tested. During testing, the two sets of connecting blocks are staggered on the outside of the circular groove, and the position of the positioning component and the testing mechanism is adjusted by the adjustment mechanism, which makes it convenient to perform strength testing on the circular grooves opened on cement pipes of different sizes.
[0020] This utility model is equipped with a baffle and a stop block. When testing a cement pipe, the movable frame is driven to unfold outward by the second drive structure. At this time, the baffle on the movable frame is squeezed by the inner wall of the cement pipe, causing the baffle to move downward. Through the stop block, the downward movement of the baffle causes the rebound hammer to move out from inside the connecting block. When the pressure continues, the rebound hammer squeezes the pipe wall, thereby being used to test the strength of the inner wall of the cement pipe. This ensures that it does not affect the strength test of the circular groove, thus improving the practicality of the device. Attached Figure Description

[0029] 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.
[0030] Example 1
[0031] like Figures 1 to 7 As shown, this is the first embodiment of the utility model, which provides a prefabricated component strength testing device, including a base frame 1, a material rack mechanism 2 is provided on the top of the base frame 1, an adjustment mechanism 3 is provided on the top of the base frame 1 located on the right side of the material rack mechanism 2, a positioning component 4 is provided inside the adjustment mechanism 3, and a testing mechanism 5 is provided outside the positioning component 4.
[0032] The positioning component 4 includes a support rod 405, a second drive structure 406 is provided inside the support rod 405, and movable blocks 407 are threadedly sleeved on both sides of the output shaft of the second drive structure 406. A connecting plate 403 is hinged to the outside of the movable block 407, and a movable frame 404 is hinged to the other end of the connecting plate 403.
[0033] The testing mechanism 5 includes a connecting block 501. Two sets of connecting blocks 501 are provided. The two sets of connecting blocks 501 are fixed and movably sleeved in the inner cavity of the movable frame 404. A rebound hammer 502 is provided in the inner cavity of each set of connecting blocks 501. A pressure block 503 is provided on the outside of the rebound hammer 502. An inclined block 504 located below the pressure block 503 is provided on the inner wall of each set of connecting blocks 501. A connecting post 505 is provided at the bottom of the rebound hammer 502. The connecting post 505 extends to the outside of the connecting block 501 and is sleeved with a baffle 506. The baffle 506 is elastically connected to the connecting post 505 by a spring 507.
[0034] When the operator tests the strength of the circular groove on the outside of the precast cement pipe component for water pipe insertion, the distance between the two sets of connecting blocks 501 is adjusted to the diameter of the cement pipe. Then, the positioning component 4 is extended into the circular groove via the adjustment mechanism 3. The drive structure 406 is then activated, moving the movable block 407. Due to the hinge between the movable block 407 and the connecting plate 403, the movable frame 404 is extended outward via the connecting plate 403, creating a gap between the movable frame 404 and the inner wall of the circular groove. Simultaneously, the two sets of connecting blocks 501 are located on the outside and inside of the cement pipe, respectively. The adjustment mechanism 3 then moves the positioning component 4 and the testing mechanism 5. The baffle 506 is pressed against the outer wall of the circular groove. The obstruction of the baffle 506 causes the connecting column 505 and the rebound hammer 502 to move outward. During the movement of the rebound hammer 502, the pressure block 503 is pressed by the inclined block 504, causing the rebound hammer 502 to move backward. The mechanism moves upward and removes the rebound hammer 502 from the inner cavity of the connecting block 501. Since the cement pipe groove is not on the same level, the adjustment mechanism 3 needs to continue to drive the movable frame 404 to move, so that the rebound hammer 502 that has been removed from the connecting block 501 moves in the horizontal part of the inclined block 504. When all the rebound hammers 502 are removed from the inside of the connecting block 501, the second drive structure 406 is activated again to drive the movable frame 404 to unfold, and the rebound hammer 502 is pressed against the inner wall of the groove. The rebound hammer 502 strikes the concrete surface of the inner wall of the cement pipe through the impact rod inside the rebound hammer 502. The energy generated by the change of the working length of the impact spring is measured and the rebound force related to the hardness of the concrete surface is calculated to calculate the strength of the concrete. Thus, the strength test of the inner wall of the groove is completed. The rebound hammers 502 on the two sets of connecting blocks 501 can simultaneously perform strength tests on multiple points, which reduces the operation process and brings convenience to the operator.
[0035] The rebound hammer 502 is an existing technology that uses the principle of energy conservation to convert the surface hardness of concrete into a rebound value. Then, it establishes the relationship between the rebound value and compressive strength through statistical laws, enabling rapid and non-destructive testing of concrete strength.
[0036] Example 2
[0037] like Figure 3 and Figure 5 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that a spring 508 is sleeved on the outer surface of the connecting post 505, and the two sides of the spring 508 are respectively connected to the connecting post 505 and the connecting block 501.
[0038] When the baffle 506 is pressed by the outer wall of the circular groove, the baffle 506 is obstructed, causing the connecting column 505 and the rebound hammer 502 to move as a whole. The top of the rebound hammer 502 is moved out of the inner cavity of the connecting block 501 by the inclined block 504 for strength testing. At the same time, when the obstruction of the baffle 506 is released, the spring 3 508 is in a compressed state, which will apply inward pressure to the connecting column 505, causing the rebound hammer 502 to reset and move back into the inner cavity of the connecting block 501 for subsequent circular groove testing.
[0039] Among them, a moving block is movably connected to the outside of the rebounder 502, the outside of the moving block is movably sleeved with the inner wall of the connecting block 501, and the moving block is elastically connected to the rebounder 502 through spring 509.
[0040] When the rebound hammer 502 moves out of the inner cavity of the connecting block 501, the spring 509 deforms and is in a compressed state, which will apply downward pressure to the rebound hammer 502, so as to move the rebound hammer 502 into the inner cavity of the connecting block 501 for subsequent strength testing of the prefabricated components. At the same time, the design of the moving block prevents the rebound hammer 502 from being obstructed by the spring 509 when it moves.
[0041] Among them, a stop block 510 is provided on the inner side of the baffle 506, and the inner side of the stop block 510 extends into the inner cavity of the connecting block 501;
[0042] When the cement pipe is being tested for strength, the drive structure 406 moves the movable frame 404 outward. The movable frame 404 then causes the two sets of connecting blocks 501 to adhere to the inner wall of the cement pipe. This causes the inner wall to press against the top of the baffle 506, moving the baffle 506 outside the connecting column 505. Simultaneously, due to the design of the stop block 510, the baffle 506 moves outward, releasing its contact with the connecting block 501. The stop block 510 then obstructs the rebound hammer 502 from... The inner cavity of the connecting block 501 is moved out so that it can be used to test the strength of the cement pipe. After the test is completed, the movable frame 404 is moved away from the inner wall of the cement pipe. Through the elastic force of the second spring 507, the baffle 506 is driven to reset so that it can be used to test the strength of the outer circular groove of the cement pipe. By moving the position of the baffle 506, the baffle 506 is made flush with the connecting block 501 and the rebound hammer 502 is moved out from the inner cavity of the connecting block 501 so that it can be used to test the inner wall of the cement pipe.
[0043] Among them, the movable frame 404 has a slot 402 on the outside, and a bolt 408 is provided inside the slot 402. The bottom of the bolt 408 extends into the inner cavity of the connecting block 501.
[0044] By rotating bolt 408, bolt 408 is moved out of the connecting block 501, releasing the fixing of the connecting block 501. Then, the distance between the two sets of connecting blocks 501 is adjusted so that it is the same as the wall thickness plus inner diameter of the precast cement pipe, so as to use it for strength testing of the circular groove opened on the cement pipe, making it suitable for testing cement pipes of different diameters.
[0045] Among them, the outer side of the support rod 405 is movably sleeved inside the adjustment mechanism 3, and a drive structure 401 is provided on the outer side of the support rod 405;
[0046] When the drive structure 401 is started, it drives the support rod 405 to rotate, which is used to adjust the position of the rebound hammer 502 inside the cement pipe, so that it can be used to perform strength testing at different locations, and improve the accuracy by conducting multiple tests.
[0047] Example 3
[0048] like Figure 2 , Figure 4 and Figure 6 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the material rack mechanism 2 includes a rotating component 201, a disk is provided on the top of the rotating component 201, a drive component 202 is provided inside the disk, and a limit frame 203 is threadedly sleeved on both sides of the output shaft of the drive component 202.
[0049] By activating the drive component 202, the position of the limit frame 203 on the disc is adjusted so that it can be used to place cement pipes of different sizes for subsequent testing. At the same time, the rotation component 201 adjusts the position of the cement pipe on the material rack mechanism 2, making it convenient for operators to test the strength at different positions, avoiding increasing the workload during testing, and bringing convenience to the operators.
[0050] The adjustment mechanism 3 includes a second drive assembly 301 and a connecting rod 303. The outer sides of the second drive assembly 301 and the connecting rod 303 are connected to the inner wall of the base frame 1. The output shaft of the second drive assembly 301 is threaded with a connecting frame 302. The inner wall of the connecting frame 302 is movably connected to the outer surface of the connecting rod 303.
[0051] When the drive assembly 301 is activated, it drives the connecting frame 302 to move on the outer surface of the connecting rod 303, thereby facilitating the overall movement of the positioning assembly 4 and the detection mechanism 5 into the cement pipe for detecting the strength at different locations in the cement pipe.
[0052] Among them, a pneumatic cylinder 304 is provided on the top of the connecting frame 302, and a mounting frame 305 is provided on the top of the pneumatic cylinder 304. The bottom of the mounting frame 305 extends into the inner cavity of the connecting frame 302, and the inner wall of the mounting frame 305 is movably connected to the outer side of the support rod 405.
[0053] The pneumatic cylinder 304 is activated to move the mounting bracket 305 upward as a whole, which is used to adjust the position and height of the positioning component 4 and the detection mechanism 5, so that the positioning component 4 can be moved to the center position of the cement pipe. At the same time, it is also used to perform strength testing on cement pipes of different sizes.
[0054] Working principle and usage process of this utility model:
[0055] First, when performing strength testing on a cement pipe, the cement pipe to be tested is placed on the limiting frame 203. The limiting frame 203 limits the cement pipe, and the rotating component 201 is activated to make the cement pipe level with the positioning component 4. Then, the pneumatic cylinder 304 is activated to move the mounting frame 305 and the positioning component 4 as a whole, so that it holds the positioning component 4 at the axis of the cement pipe. Then, the drive component 2 301 drives the connecting frame 302, the mounting frame 305 and the positioning component 4 as a whole to move into the inner cavity of the cement pipe. The drive structure 2 406 is activated to move the movable block 407. Due to the hinge between the movable block 407 and the connecting plate 403, the movable frame 404 is moved outward. Then, the top of the baffle 506 is in contact with the water. The inner wall of the mud pipe is squeezed, causing the baffle 506 and the stop block 510 to move downwards. The stop block 510 moves the baffle 506 away from the outside of the connecting block 501. At the same time, the rebound hammer 502 is pulled outwards through the connecting column 505 and the inclined block 504, so that it moves out of the inner cavity of the connecting block 501. Then, as the movable frame 404 continues to move, the rebound hammer 502, which has moved out of the inner cavity of the connecting block 501, squeezes the inner wall of the cement pipe to test the strength of the cement pipe. After the test is completed, the movable frame 404 is reset, and the drive structure 401 is activated to move the position of the rebound hammer 502 so that it can test other points again. At the same time, the position of the connecting frame 302 is moved so that it can be used to test the strength of the cement pipe at different positions, thereby improving the accuracy of the test.
[0056] Then, when inspecting the circular groove on the outside of the cement pipe, the rotating component 201 is activated to rotate the cement pipe, aligning the center of the circular groove with the positioning component 4. The bolt 408 is then rotated to move out of the connecting block 501. The distance between the two sets of connecting blocks 501 is then adjusted to match the inner diameter plus wall thickness. The second drive component 301 is activated to move the positioning component 4 into the inner cavity of the circular groove, causing the two sets of connecting blocks 501 to be staggered with the two circular grooves. The second drive structure 406 is then activated, using the movable block 407 and connecting plate 403 to extend the movable frame 404 outwards, moving it to the outside of the circular groove and stopping it. Simultaneously, the baffle 506 exceeds the size of the circular groove. The second drive component 301 is then activated to move the positioning component 4 outwards. The baffle 506 is blocked by the outside of the circular groove, causing the connecting column 505 and the spring to move outwards. As the rebound hammer 502 moves outward, the pressure block 503 on the outer side of the rebound hammer 502 is blocked by the inclined block 504, causing the rebound hammer 502 to move out of the inner cavity of the connecting block 501. As the positioning component 4 continues to move, it moves all the rebound hammers 502 out of the connecting block 501, and all the rebound hammers 502 are positioned in the same way as the circular groove and are located on the inner wall of the circular groove. Then, the second drive structure 406 is activated, which drives the movable frame 404 and the rebound hammers 502 to unfold outward, so as to detect the strength at the circular groove. At the same time, the movable frame 404 is reset and the positioning component 4 is rotated as a whole through the first drive structure 401 to adjust the position of the rebound hammers 502 for strength testing at different positions of the circular groove. This makes it easier to test the strength of the circular groove opened on the cement pipe, so that the position of the rebound hammers 502 does not need to be adjusted many times, reducing the difficulty of operation and the time required, and bringing convenience to the operator.
