Description

Technical Field

[0001] This application relates to the field of testing devices, and in particular to a testing frame for a segment reinforcement cage. Background Technology

[0002] Precast concrete shield tunnel segments are used in shield tunnel construction. During the manufacturing process, a reinforcing cage is placed in a steel mold before concrete is poured. The reinforcing cage forms a complete grid through the combination of reinforcing bars, which helps to restrain the concrete and improve the overall integrity of the concrete structure. The reinforcing cage needs to be inspected after production.

[0003] In related technologies, the rebar cage hoisting equipment for tunnel segments is used to lift the steel cage to the scanning and inspection position. However, manual alignment is required, which can easily lead to large deviations in the placement of the scanning area due to differences in experience and shaking during hoisting. This requires a lot of time for correction, resulting in low inspection efficiency. Therefore, improvements are needed. Utility Model Content

[0004] To improve the inspection efficiency of tunnel segment reinforcement cages, this application provides an inspection frame for tunnel segment reinforcement cages.

[0005] The inspection frame for the steel reinforcement cage of the tunnel segment provided in this application adopts the following technical solution: A testing frame for a steel reinforcement cage of a tunnel segment includes a base and a limiting assembly. The limiting assembly includes a limiting frame, a limiting plate, and multiple limiting seats. The limiting frame is disposed on the upper side of the base. The limiting plate is disposed on one side of the limiting frame, and the limiting plate and the upper side of the limiting frame form multiple limiting grooves, which are spaced apart circumferentially along the upper side of the limiting frame. The multiple limiting seats are disposed at one end of the limiting frame and spaced apart along the width direction of the base.

[0006] By adopting the above technical solution, in practical applications, the hoisting equipment lifts the segment reinforcement cage to the inspection frame, so that the segment reinforcement cage is placed on the upper side of the limiting frame. One end of the segment reinforcement cage abuts against multiple limiting seats, and the segment reinforcement cage is limited in multiple limiting grooves, so as to achieve the positioning of the segment reinforcement cage. This can ensure that the segment reinforcement cage is lifted to the accurate scanning and inspection position as much as possible, without having to spend time on calibration, thereby improving the inspection efficiency of the segment reinforcement cage.

[0007] Preferably, the limiting frame includes two mounting plates and a connecting frame. The two mounting plates are spaced apart on the base along the width direction of the base, and the connecting frame is disposed between the two mounting plates and arranged along the circumference of the mounting plates.

[0008] By adopting the above technical solution, two mounting plates and a connecting frame are set up. The two mounting plates are connected to the base and provide an installation foundation for the connecting frame. The connecting frame is used for limiting the placement of the segment reinforcement cage.

[0009] Preferably, the limiting frame further includes two reinforcing plates, which are disposed between the two mounting plates and spaced apart along the length of the base.

[0010] By adopting the above technical solution and setting two reinforcing plates, the stability of the connection between the two mounting plates is improved, thereby increasing the overall structural strength of the limit frame and ensuring the stability of the support for the steel cage of the pipe segment.

[0011] Preferably, the limiting frame further includes a plurality of limiting posts, which are threadedly connected to the upper side of the two reinforcing plates and spaced apart along the length of the reinforcing plates.

[0012] By adopting the above technical solution, multiple limiting posts are set to further limit the rebar cage of the segment, thereby improving the stability of the segment rebar cage limitation. The limiting posts are threaded to the reinforcing plate, so as to facilitate the replacement of limiting posts of different sizes to meet the limitation requirements of different rebar cages.

[0013] Preferably, the limiting post has a stepped surface, which abuts against the upper side of the reinforcing plate.

[0014] By adopting the above technical solution and setting a stepped surface, the positioning and installation of the limiting post can be facilitated.

[0015] Preferably, the limiting post is provided with multiple force-applying grooves spaced apart along its circumference.

[0016] By adopting the above technical solution and setting multiple force-applying grooves, the limit post can be rotated with tools such as wrenches, thereby facilitating the installation and disassembly of the limit post.

[0017] Preferably, the mounting plate is detachably connected to the base.

[0018] By adopting the above technical solution, and by setting the mounting plate to be detachably connected to the base, the limiting component and the base can be detachably connected, and different limiting components can be replaced to suit different sizes of segment reinforcement cages.

[0019] Preferably, the limiting frame further includes a pin, which is sequentially inserted into the mounting plate and the base.

[0020] By adopting the above technical solution and setting a pin, a detachable connection between the mounting plate and the base can be achieved, which is simple in structure and easy to operate.

[0021] Preferably, the limiting component further includes a plurality of sensors, which are disposed on one side of the two mounting plates that are close to each other.

[0022] By adopting the above technical solution and setting up multiple sensors, it is possible to detect whether the steel reinforcement cage for the tunnel segment has been placed in place.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. In practical applications, the hoisting equipment lifts the segment reinforcement cage to the inspection frame, so that the segment reinforcement cage is placed on the upper side of the limiting frame. One end of the segment reinforcement cage abuts against multiple limiting seats, and the segment reinforcement cage is limited in multiple limiting grooves to achieve the positioning of the segment reinforcement cage. This can ensure that the segment reinforcement cage is lifted to the accurate scanning and inspection position as much as possible, without having to spend time on calibration, thereby improving the inspection efficiency of the segment reinforcement cage. 2. By setting multiple limiting posts, the limiting posts further limit the rebar cage of the segment to improve the stability of the segment rebar cage limitation. The limiting posts are threaded to the reinforcing plate to facilitate the replacement of limiting posts of different sizes to meet the limitation requirements of different rebar cages. 3. By setting an installation plate that can be detachably connected to the base, the limit component and the base can be detachably connected, and different limit components can be replaced to suit different sizes of segment reinforcement cages.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses an inspection frame for a segment reinforcement cage.

[0030] Reference Figure 1 The inspection frame includes a base 1 and a limiting component 2. The base 1 is a rectangular seat and is placed horizontally at the scanning inspection point of the steel cage of the pipe segment.

[0031] Reference Figure 1 and Figure 2 The limiting component 2 includes a limiting frame 21, a limiting plate 22 and multiple limiting seats 23. The limiting frame 21 is fixedly connected to the upper side of the base 1. The shape of the limiting frame 21 is adapted to the shape of the segment reinforcement cage so as to limit the placement of the segment reinforcement cage.

[0032] The limiting plate 22 is fixedly connected to one side of the limiting frame 21, and a plurality of limiting grooves 24 are formed between the limiting plate 22 and the upper side of the limiting frame 21. The plurality of limiting grooves 24 are evenly spaced along the circumferential direction of the upper side of the limiting frame 21. A plurality of limiting seats 23 are fixedly connected to one end of the limiting frame 21, and the plurality of limiting seats are spaced apart along the width direction of the base 1.

[0033] In practical applications, the hoisting equipment lifts the segment reinforcement cage to the top of the base 1, so that the segment reinforcement cage is placed on the upper side of the limiting frame 21. At the same time, one end of the segment reinforcement cage abuts against multiple limiting seats 23 and is limited in multiple limiting grooves 24, so as to achieve the positioning of the segment reinforcement cage. This can ensure that the segment reinforcement cage is lifted to the accurate scanning and detection position as much as possible, without having to spend time on calibration, thereby improving the detection efficiency of the segment reinforcement cage.

[0034] In some embodiments, the limiting frame 21 includes two mounting plates 211 and a connecting frame 212. The two mounting plates 211 are spaced apart along the width direction of the base 1 and are mounted on the upper side of the base 1 to achieve the connection between the limiting frame 21 and the base 1. The connecting frame 212 is fixedly connected between the two mounting plates 211 and is arranged circumferentially along the mounting plates 211 to ensure the stability of the connection between the two mounting plates 211 and to support the segment reinforcement cage, thereby achieving the limiting placement of the segment reinforcement cage.

[0035] In some embodiments, the limiting frame 21 further includes two reinforcing plates 213, which are arranged along the length of the base 1, and the two ends of the reinforcing plates 213 are respectively fixedly connected to the two mounting plates 211 to improve the stability of the connection between the two mounting plates 211, thereby improving the overall structural strength of the limiting frame 21 and ensuring the stability of the support for the steel cage of the pipe segment.

[0036] In some embodiments, the limiting frame 21 further includes a plurality of limiting posts 214. The plurality of limiting posts 214 are threadedly connected to the upper side of two reinforcing plates 213 and are spaced apart along the length direction of the reinforcing plates 213. The limiting posts 214 are higher than the upper side of the mounting plate 211 to limit the segment reinforcement cage, thereby improving the stability of the segment reinforcement cage limitation. The limiting posts 214 are threadedly connected to the reinforcing plates 213 so as to facilitate the replacement of limiting posts 214 of different sizes to meet the limitation requirements of different reinforcement cages.

[0037] Reference Figure 3 In some embodiments, the limiting post 214 has a stepped surface 214a. When the limiting post 214 is installed on the reinforcing plate 213, the stepped surface 214a abuts against the upper side of the reinforcing plate 213 to facilitate the positioning and installation of the limiting post 214.

[0038] In some embodiments, the limiting post 214 is provided with a plurality of force-applying grooves 214b evenly spaced along its circumference, so as to facilitate the rotation of the limiting post 214 with the help of tools such as wrenches, so as to facilitate the installation and disassembly of the limiting post 214, thereby facilitating the replacement of the limiting post 214.

[0039] Reference Figure 1 and Figure 2 In some embodiments, the mounting plate 211 is detachably connected to the base 1 to achieve a detachable connection between the limiting component 2 and the base 1, and the limiting component 2 of different sizes can be replaced to be suitable for steel cages of different sizes, thereby improving the applicability of the inspection frame.

[0040] In some embodiments, the limiting bracket 21 further includes pins 215, which are sequentially inserted into the mounting plate 211 and the base 1 to achieve a detachable connection between the mounting plate 211 and the base 1. The structure is simple and easy to operate. It should be noted that one mounting plate 211 corresponds to two pins 215, and the two pins 215 are located at both ends of the mounting plate 211 to ensure the stability of the mounting plate 211 during installation.

[0041] In some embodiments, the limiting component 2 further includes a plurality of sensors 25, which are evenly arranged on one side of the two mounting plates 211 that are close to each other, to detect whether the segment reinforcement cage is placed in place, thereby improving the accuracy of the segment reinforcement cage placement.

[0042] The implementation principle of this embodiment is as follows: In practical applications, the hoisting equipment hoists the segment reinforcement cage to the top of the base 1, so that the segment reinforcement cage is placed on the upper side of the limiting frame 21. At the same time, one end of the segment reinforcement cage abuts against multiple limiting seats 23, and the segment reinforcement cage is limited in multiple limiting grooves 24, so as to realize the positioning of the segment reinforcement cage. This can ensure that the segment reinforcement cage is hoisted to the accurate scanning and detection position as much as possible, without having to spend time on calibration, thereby improving the detection efficiency of the segment reinforcement cage.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
