Description

Technical Field

[0001] This utility model relates to the field of finished concrete pipe segment production, specifically a pressure testing device for finished concrete pipe segments. Background Technology

[0002] Subway tunnel segments are commonly used in the construction of subway tunnels. As a type of precast concrete segment, subway tunnel segments mainly serve a supporting and waterproofing function during tunnel excavation. The production process of precast tunnel segments is complex, involving many steps and requiring high precision. The production technology of precast tunnel segments mainly includes concrete preparation, steel reinforcement skeleton and its forming technology, vibration molding, segment demolding, concrete curing and reverse transportation technology, etc. The quality of precast tunnel segments is directly related to the overall quality and safety of the tunnel, affecting the tunnel's waterproof performance and durability. Therefore, as the main body of shield tunnels, precast tunnel segments are related to the quality and safety of the entire tunnel. Among them, the testing of the compressive strength of precast tunnel segments is crucial, so pressure testing devices are needed to perform pressure testing on concrete tunnel segments.

[0003] According to Chinese Patent No. CN219319977U, a pressure testing bench for precast reinforced concrete segments is disclosed. This utility model solves the problem that existing pressure testing benches for precast reinforced concrete segments can only test segments of a single diameter and cannot test segments of different diameters, thus reducing the practicality of the pressure testing bench in use.

[0004] Regarding the aforementioned disclosed patent content, two placement seats are provided to place precast concrete segments between the two placement seats. At the same time, two electric drive mechanisms are installed on both sides inside the device. The operation of the electric drive mechanisms can drive the support plate to move, so that the support plate can support the placement seats when pressure testing the precast concrete segments, thereby improving the stability of the placement seats. However, the frequent use of multiple electric drive mechanisms to drive the support plate to move will increase energy consumption and increase the operating cost of the device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pressure testing device for finished concrete pipe segments, so as to solve the technical problem that driving the support plate to move through multiple electric drive mechanisms will increase the energy consumption of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure testing device for finished concrete pipe segments, comprising a base plate and a mounting base. A support frame is installed on the top of the base plate, and stabilizing components are provided on both sides of the interior of the support frame. The stabilizing components include movable frames installed on both sides of the mounting base, openings on both sides of the top of the support frame, and sliding grooves and sliding rods provided on both sides of the interior of the support frame. A sliding seat is fitted on the outer wall of the sliding rod, and multiple spring rods are installed on one side of the sliding seat. One end of the spring rod is connected to a support plate. A return spring is installed at the bottom of the interior of the sliding groove, and a slider is installed at the top of the return spring. A lifting plate is fixed on one side of the slider, and a rotating plate is connected to the lifting plate and the sliding seat through a rotating shaft. A threaded rod is threadedly connected to the movable frame, and a pad is fixed at the bottom end of the threaded rod.

[0007] By adopting the above technical solution, when the lifting plate moves down, it can push the rotating plate to rotate, which in turn can push the slide to move, and the slide can drive the spring rod and the support plate to move.

[0008] Furthermore, a hydraulic cylinder is installed on the top of the support frame, and a mounting base is installed on the output end of the hydraulic cylinder via a piston rod.

[0009] By adopting the above technical solution, when the pressure plate needs to be moved down, the operator can activate the hydraulic cylinder to extend the piston rod, thereby moving the mounting base down and then moving the pressure plate down.

[0010] Furthermore, the bottom of the mounting base is provided with a threaded groove, the inside of which is threaded with a threaded head, and a pressure plate is installed at the bottom end of the threaded head.

[0011] By adopting the above technical solution, when installing the pressure plate, simply screw the threaded head on the pressure plate into the threaded groove, and the installation of the pressure plate can be completed.

[0012] Furthermore, a pressure sensor is installed above the inside of the threaded groove, and the pressure plate is detachably connected to the mounting base via a threaded head.

[0013] By adopting the above technical solution, the pressure sensor can detect the pressure, and the staff can disassemble and assemble the pressure plate to replace it.

[0014] Furthermore, a guide rod that penetrates the support frame is installed at the top of the movable frame.

[0015] By adopting the above technical solution, the movable frame will drive the guide rod to move when it moves, so as to improve the stability of the movable frame when it moves.

[0016] Furthermore, the top of the base plate is provided with a fixed platform, and grooves are provided on both sides of the top of the fixed platform. A motor is installed on one side of the fixed platform, and the output end of the motor is connected to a bidirectional lead screw extending into the groove.

[0017] By adopting the above technical solution, when it is necessary to move the placement seat, the motor can be started. The operation of the motor can drive the bidirectional lead screw to rotate, thereby driving the two movable seats to move.

[0018] Furthermore, the outer wall of the bidirectional lead screw is fitted with two movable seats, and a placement seat is installed on the top of the movable seats.

[0019] By adopting the above technical solution, the placement seat facilitates the placement of concrete segments.

[0020] Furthermore, a control panel is installed on one side of the support frame, and the control panel is electrically connected to the motor, pressure sensor and hydraulic cylinder respectively.

[0021] By adopting the above technical solution, the motor, pressure sensor and hydraulic cylinder can be started or stopped via the control panel.

[0022] Furthermore, the lifting plate is located directly below the threaded rod, and the lifting plate is slidably connected to the slide groove via a slider.

[0023] By adopting the above technical solution, when the threaded rod moves down, it will push the lifting plate down, and the lifting plate will drive the slider to slide inside the groove, thereby improving the stability of the lifting plate when it moves.

[0024] Furthermore, the slide block is slidably connected to the slide rod, and the support plate is located on one side of the placement seat.

[0025] By adopting the above technical solution, the slide block can slide on the slide rod, thereby improving the stability of the slide block when sliding.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model incorporates a stabilizing component. When the mounting base moves the pressure plate downward, it moves the movable frame downward, which in turn moves the threaded rod downward. The threaded rod then pushes the lifting plate downward. As the lifting plate moves downward, it can rotate the rotating plate, which in turn can move the sliding block. The sliding block then moves the spring rod and the support plate, allowing one side of the support plate to fit against the side of the placement seat. As the lifting plate continues to move downward, the spring rod is compressed. At this point, the support plate, under the reaction force of the spring rod, will fit tightly against the placement seat, thereby improving the stability of the placement seat. In this way, only the mounting base needs to move the movable frame downward to make the support plate fit against the side of the placement seat, eliminating the need for four electric drive mechanisms to move the support plate. This reduces the number of electrical components, lowers energy consumption, and reduces the cost of using the device.

[0028] 2. This utility model is equipped with a threaded rod, which allows workers to adjust the distance between the bottom end of the threaded rod and the lifting plate according to the position of the placement seat, so as to accommodate concrete pipe segments of different diameters. The adjustment process is that the workers directly rotate the threaded rod, which moves the threaded rod on the movable frame, thereby quickly adjusting the distance between the bottom end of the threaded rod and the lifting plate.

[0029] 3. This utility model is equipped with a return spring. When the slider slides inside the groove, it will squeeze the return spring, so that the return spring is compressed and the slider is pushed up to return to its original position. By providing a slide rod, the slide block is guided, thereby improving the stability of the slide block when it moves. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A pressure testing device for finished concrete tunnel segments, such as Figures 1-6 As shown, the device includes a base plate 1 and a mounting base 5. A support frame 2 is mounted on the top of the base plate 1, and stabilizing components 9 are provided on both sides of the inside of the support frame 2. A hydraulic cylinder 4 is mounted on the top of the support frame 2, and the output end of the hydraulic cylinder 4 is mounted on the mounting base 5 through a piston rod. When it is necessary to move the pressure plate 8 down, the operator can activate the hydraulic cylinder 4 to extend the piston rod, thereby moving the mounting base 5 down and then moving the pressure plate 8 down. A threaded groove 6 is provided at the bottom of the mounting base 5, and a threaded head 7 is threadedly connected inside the threaded groove 6. The pressure plate 8 is mounted at the bottom end of the threaded head 7. When installing the pressure plate 8, simply screw the threaded head 7 on the pressure plate 8 into the threaded groove 6 to complete the installation of the pressure plate 8. A pressure sensor 10 is installed above the inside of the threaded groove 6. The pressure plate 8 is detachably connected to the mounting base 5 through the threaded head 7. The pressure sensor 10 can detect the pressure, and the operator can disassemble and assemble the pressure plate 8 for replacement.

[0041] See Figures 1-5 The base plate 1 has a fixed platform 12 on its top, and grooves 13 are provided on both sides of the top of the fixed platform 12. A motor 17 is installed on one side of the fixed platform 12. The output end of the motor 17 is connected to a bidirectional lead screw 14 extending into the groove 13. When the placement seat 16 needs to be moved, the motor 17 can be started. The operation of the motor 17 can drive the bidirectional lead screw 14 to rotate, thereby driving the two movable seats 15 to move. Two movable seats 15 are sleeved on the outer wall of the bidirectional lead screw 14. The movable seats 15 are threadedly connected to the bidirectional lead screw 14. The placement seat 16 is installed on the top of the movable seat 15. The placement seat 16 is designed to facilitate the placement of concrete pipe segments. A control panel 3 is installed on one side of the support frame 2. The control panel 3 is electrically connected to the motor 17, the pressure sensor 10 and the hydraulic cylinder 4 respectively, so that the motor 17, the pressure sensor 10 and the hydraulic cylinder 4 can be started or stopped through the control panel 3.

[0042] See Figures 1-4The stabilizing component 9 includes a movable frame 909 installed on both sides of the mounting base 5, through openings 904 on both sides of the top of the support frame 2, and a slide groove 906 and a slide rod 902 located on both sides inside the support frame 2. The top side of the movable frame 909 passes through the through opening 904, allowing the movable frame 909 to move smoothly. The outer wall of the slide rod 902 is fitted with a slide seat 903, and multiple spring rods 911 are installed on one side of the slide seat 903. One end of the spring rod 911 is connected to a support plate 912. A return spring 901 is installed at the bottom inside the slide groove 906, and a slider 907 is installed at the top of the return spring 901. A lifting plate 908 is fixed on one side of the slider 907, and a rotating plate 913 is connected between the lifting plate 908 and the slide seat 903 via a rotating shaft. A through hole 905 passes through one side of the support plate 912, and the diameter of the slide rod 902 is smaller than the diameter of the through hole 905.

[0043] Specifically, the movable frame 909 is threadedly connected to a threaded rod 910, and a pad is fixed to the bottom end of the threaded rod 910. When the lifting plate 908 moves down, it can push the rotating plate 913 to rotate. The rotating plate 913 can then push the slide 903 to move. The slide 903 then drives the spring rod 911 and the support plate 912 to move. The lifting plate 908 is located directly below the threaded rod 910. The lifting plate 908 is slidably connected to the slide groove 906 through the slider 907. When the threaded rod 910 moves down, it pushes the lifting plate 908 to move down. The lifting plate 908 then drives the slider 907 to slide inside the slide groove 906, thereby improving the stability of the lifting plate 908 when it moves. The slide 903 is slidably connected to the slide rod 902. The support plate 912 is located on one side of the placement seat 16 so that the slide 903 can slide on the slide rod 902, thereby improving the stability of the slide 903 when it slides.

[0044] Example 2:

[0045] Based on the above embodiment 1, the following structure will be set to improve the stability of the movable frame 909 when it moves.

[0046] See Figure 1 , Figure 2 , Figure 3 and Figure 5 The top of the movable frame 909 is equipped with a guide rod 11 that passes through the support frame 2. When the movable frame 909 moves, it will drive the guide rod 11 to move, so as to improve the stability of the movable frame 909 when it moves.

[0047] The working principle of this utility model is as follows: First, when using it, the operator first connects the power supply, and then adjusts the distance between the two placement seats 16 according to the diameter of the concrete pipe segment. The operator can start the motor 17. The operation of the motor 17 can drive the bidirectional screw 14 to rotate, thereby driving the two movable seats 15 to move, and driving the placement seats 16 to move, thereby adjusting the position of the two placement seats 16. After the adjustment is completed, the motor 17 is turned off. Then, the operator adjusts the distance between the bottom end of the threaded rod 910 and the lifting plate 908 according to the position of the placement seats 16, so that when the pressure plate 8 moves down to apply pressure to the concrete pipe segment, the support plate 912 can fit against the side of the placement seat 16. The adjustment process is that the operator directly rotates the threaded rod 910, so that the threaded rod 910 moves on the movable frame 909. After adjusting to the appropriate position, the operator no longer needs to rotate the threaded rod 910. In this way, the distance between the bottom end of the threaded rod 910 and the lifting plate 908 can be quickly adjusted.

[0048] Next, the workers placed the concrete segment between the two placement seats 16, then activated the hydraulic cylinder 4, causing the piston rod to extend, which in turn moved the mounting seat 5 downwards, and then the pressure plate 8 downwards, so that the pressure plate 8 could apply pressure to the concrete segment. The pressure sensor 10 can detect the pressure. At the same time, the mounting seat 5 moved the movable frame 909 downwards, and then moved the threaded rod 910 downwards. The threaded rod 910 pushed the lifting plate 908 downwards. When the lifting plate 908 moved downwards, it caused the slider 907 to slide inside the slide groove 906, and squeezed the return spring 901. The rotating plate 913 is pushed to rotate, which in turn pushes the slide 903 to move. The slide 903 then drives the spring rod 911 and the support plate 912 to move, so that one side of the support plate 912 can fit against the side of the placement seat 16. As the mounting seat 5 continues to drive the movable frame 909 to move down, the lifting plate 908 will also continue to move down. At this time, the slide 903 continues to move and squeeze the spring rod 911, so that the spring rod 911 is compressed. The support plate 912 will be tightly fitted against the placement seat 16 by the reaction force of the spring rod 911, thereby improving the stability of the placement seat 16.
