[0046] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0047] like Figure 1 As shown, the present invention provides a device for detecting the deviation of a corrugated tube in the prestressed construction of a continuous beam, comprising:

[0048] A support platform 1, with adjustable legs 2 disposed below the support platform 1;

[0049] A support frame, which is arranged on the upper side of the support platform 1, and a laser emitting component 3 is arranged inside the support frame;

[0050] The first target plate 4 and the second target plate are transparent and are detachably connected to the two ends of the bellows 21, respectively. The laser beam 22 emitted by the laser emitting component 3 can pass through the first target plate 4 and the second target plate, and leave light spots on the first target plate 4 and the second target plate;

[0051] The transverse centering structure includes a pair of limit rods 5 connected to one end of the support frame, and the pair of limit rods 5 are respectively used to be arranged on both sides of the corrugated pipe 21.

[0052] Specifically, in order to solve the problem of insufficient accuracy in detecting the offset of the corrugated pipe 21 in the prestressed continuous beam construction in the prior art; the corrugated pipe offset detection device in the prestressed continuous beam construction provided by the present invention can be placed on the bottom mold in the prestressed continuous beam construction through the support platform 1, and the support platform 1 can be leveled and raised by adjusting the length of the adjustable support foot 2. The lateral centering structure can laterally center the laser emitting component 3 by limiting the position of a pair of limiting rods 5 on both sides of the corrugated pipe 21. The laser emitting component 3 on the support frame can emit a laser beam 22 into the corrugated pipe 21. By placing the first target plate 4 and the second target plate 5 on the support frame, the laser emitting component 3 can be directly connected to the corrugated pipe 21. The disks are respectively installed at the two ends of the measured section of the bellows 21. The scales on the first target disk 4 and the second target disk can be used to ensure that the laser beam 22 is incident on the bellows 21 from the center of the first target disk 4. The laser beam 22 is incident in the bellows 21 along the axis of the bellows 21, and a light spot can be left on the second target disk. By observing the position of the light spot on the second target disk, the end deviation of the bellows 21 can be detected, and the detection accuracy is high. The deviation direction and deviation amount of the end of the bellows 21 can be detected at one time, which is convenient for correcting the position of the bellows 21 and improving the installation accuracy of the bellows 21.

[0053] In this embodiment, if Figure 2 As shown, the first target plate 4 and the second target plate are made of transparent acrylic material and are circular target plates. Ring and cross scale lines are arranged on the plate surface to facilitate reading the degree and direction of the deviation of the bellows 21.

[0054] In this embodiment, the adjustable support foot 2 is threadedly connected to the support platform 1 by a threaded rod, and a structure of fastening nuts is provided on the upper side and the lower side of the support platform 1 .

[0055] Optionally, two annular protrusions 6 are provided on one side of the first target plate 4 and the second target plate, and an annular mounting groove is formed between the two annular protrusions 6 , and the mounting groove is inserted and limitedly matched with the end of the bellows 21 .

[0056] Specifically, the first target plate 4 and the second target plate are installed on the bellows 21 using a mounting groove. By inserting a small section of the bellows 21 into the mounting groove, not only the stable installation of the first target plate 4 is achieved, but the mounting groove can also form a guiding effect, so that the first target plate 4 and the second target plate are perpendicular to the axis of the bellows 21, which can improve the accuracy of detection.

[0057] Optionally, a first pin hole is respectively provided at both radial ends of the first target plate 4 and the second target plate, the limiting rod 5 is a telescopic rod, one end of the limiting rod 5 is hinged to the support frame, and the other end of the limiting rod 5 is provided with a second pin hole that cooperates with the first pin hole, and the positioning pin 7 of the transverse centering structure can be inserted into the second pin hole and the first pin hole.

[0058] Specifically, in order to facilitate the lateral centering operation and improve the lateral centering accuracy, the two limit rods 5 are connected to the first pin holes at both ends of a diameter of the first target plate 4 through the positioning pins 7. The radial ends of the first target plate 4 are matched with the limit rods 5 to achieve the lateral centering of the laser emitting component 3, and the telescopic setting of the limit rods 5 and the hinged setting of the limit rods 5 and the support frame can adapt to the adjustment of the relative position of the first target plate 4 and the support frame.

[0059] In this embodiment, the limiting rod 5 includes an inner rod and an outer rod movably mounted on the outside of the inner rod. The outer rod is rotatably connected to the support frame through a rotating pin so that it can rotate in a vertical plane. The cooperation between the inner rod and the outer rod realizes its retractable function.

[0060] Optionally, the laser emitting component 3 includes a housing 8 and an emitting head 9 disposed in the housing 8, and the emitting slope angle of the emitting head 9 is adjustable so that the angle at which the laser beam 22 is emitted from the housing 8 is adjustable.

[0061] Specifically, the emitting head 9 with an adjustable slope angle in the housing 8 of the laser emitting component 3 can emit laser beams 22 at different angles so as to detect the corrugated tube 21 with a slope.

[0062] In this embodiment, the laser emitting component 3 is a laser pipe instrument with a built-in slope angle adjustment function.

[0063] Optionally, a level is provided on the upper side of the supporting platform 1 .

[0064] Specifically, the provision of a spirit level can facilitate the leveling of the supporting platform 1 .

[0065] In this embodiment, the level is a circular bubble level.

[0066] Optionally, a lifting mechanism 10 is provided between the supporting frame and the supporting platform 1 .

[0067] Specifically, the arrangement of the lifting mechanism 10 can facilitate the adjustment of the height of the support frame and the laser emitting component 3 .

[0068] In this embodiment, the lifting mechanism 10 uses an electric lifting component, such as an electric telescopic rod, which can improve the convenience of operation and the efficiency of detection.

[0069] like Figure 3 As shown, when inspecting a corrugated pipe 21 having a slope at one end, the telescopic nature of the two limit rods 5 and the convenient adjustment of the lifting mechanism 10 can be utilized to quickly complete the lateral centering and height adjustment of the laser emitting component 3. The laser beam 22 of the laser emitting component 3 is emitted along the set slope angle to inspect the straight pipe section of the corrugated pipe 21 having a slope.

[0070] Optionally, the outer diameters of the first target disk 4 and the second target disk are larger than the outer diameter of the bellows 21.

[0071] The support frame includes:

[0072] A U-shaped frame 11, the U-shaped frame 11 is opened upward and is arranged above the lifting mechanism 10;

[0073] Two rotating rings 12, the two rotating rings 12 are rotatably connected to the two sides of the U-shaped frame 11, and the rotating rings 12 are provided with guide grooves 13 along the radial direction, and the length of the guide grooves 13 is greater than the radius length of the bellows 21;

[0074] A sliding shaft 14, both ends of which are slidably disposed in a guide groove 13, and both ends of the guide groove 13 are provided with an elastic limiting structure 15, so that the sliding shaft 14 can be located at the center of the rotating ring 12 and at the outer end of the guide groove 13;

[0075] The suspension component 16 has one end rotatably connected to the sliding shaft 14 , and the other end of the suspension component 16 is connected to the laser emitting component 3 .

[0076] Specifically, in order to further detect the middle offset of a section of the bellows 21 and further improve the installation accuracy of the bellows 21, the laser emitting component 3 is hung below the sliding shaft 14 through the suspension component 16. When detecting the end offset of the bellows 21, the sliding shaft 14 is at the center of the rotating ring 12 and is held in position by an elastic limiting structure 15. The laser beam 22 is incident along the axis of the bellows 21. When detecting the middle offset of the bellows 21, after the end offset is corrected, the middle offset is generally adaptively adjusted and the offset is relatively slight. Therefore, for this step of detection, detection efficiency is very important. In this case, the present invention provides a guide groove 13 and a sliding shaft 14. The sliding shaft 14 is slid outward along the guide groove 13 until the end offset is detected. When the laser beam 22 reaches the outside of the bellows 21, since the outer diameters of the first target plate 4 and the second target plate are larger than the outer diameter of the bellows 21, the position of the sliding shaft 14 and the distance that the laser beam 22 deviates from the bellows 21 can be set according to the accuracy requirements. Then, by rotating the rotating ring 12, the laser beam 22 can be quickly rotated around the outer circumference of the bellows 21. It is possible to judge whether there is any excessive deviation in various directions in the middle of the bellows 21 based on the display of the light spot on the second target plate. If the deviation is too much, the light path can be blocked, and the position of the bellows 21 can be conveniently adjusted by the position where the laser beam 22 hits the bellows 21. If the deviation is acceptable, there is no need to adjust the bellows 21, and the detection of the deviation of the middle of the bellows 21 can be conveniently completed in a very short time.

[0077] In this embodiment, the hanging component 16 includes a hanging rod, the upper end of the hanging rod is provided with a hole sleeved on the outer side of the sliding shaft 14, and the lower end of the hanging rod is connected to the housing 8.

[0078] Optionally, a rotating disk 17 is concentrically arranged inside each rotating ring 12, and the outer periphery of the rotating disk 17 is connected to the rotating ring 12 through a connecting rod. A rotating shaft rotatably connected to the U-shaped frame 11 is arranged on the sides of the two rotating disks 17 away from each other. The rotating disk 17 and the rotating ring 12 are respectively provided with a first opening and a second opening. Each rotating disk 17 is connected to one end of a guide rod 18 on both sides of the first opening, and the other ends of the two guide rods 18 extend through the second opening to the outside of the rotating ring 12 and are connected to the two side walls of the second opening. A guide groove 13 is formed between the two guide rods 18, and a blocking portion 19 is provided at the outer end of the guide groove 13. The blocking portion 19 is used to block the sliding shaft 14.

[0079] Specifically, the rotating ring 12 is connected to a rotating disk 17 via a connecting rod, and the rotating disk 17 is connected to the two sides of the opening of the U-shaped frame 11 via a rotating shaft on the outside of the rotating disk 17, so that the rotating ring 12 can rotate. The hole at the center of the rotating disk 17 accommodates the sliding shaft 14, and the sliding shaft 14 is located at the center of the rotating ring 12. A linear guide groove 13 is formed by the gap between the two guide rods 18, so that the sliding shaft 14 can move outward therein until the sliding shaft 14 contacts the blocking portion 19, and the sliding shaft 14 moves into place, and the guide rod 18 extends out of the rotating ring 12, so that the rotating ring 12 or the connecting rod can avoid blocking the laser beam 22 as much as possible during the rotation of the rotating ring 12, thereby improving the integrity of the detection. Figure 4 As shown, when the end deviation of the bellows 21 is detected, the sliding shaft 14 is in the rotating disk 17, and the connecting rod avoids the optical path of the laser beam 22; Figure 5 As shown, when the deviation of the middle part of the bellows 21 is detected, the sliding shaft 14 is at the outer end of the guide groove 13, and as the rotating ring 12 rotates, the laser beam 22 moves around the outer circumference of the bellows 21 for one circle.

[0080] In this embodiment, the elastic limiting structure 15 uses a spring sheet protruding outward from a guide rod 18. When the sliding shaft 14 slides over, the spring sheet is compressed and the sliding shaft 14 passes through. After the sliding shaft 14 passes through, the spring sheet rebounds and blocks the sliding shaft 14 to a certain extent.

[0081] In this embodiment, a crank 20 is provided on the rotating ring 12 to facilitate the rotation operation of the rotating ring 12 .

[0085] Level the support platform 1 and adjust the height of the support frame so that the laser beam 22 emitted by the laser emitting component 3 is incident from the center of the first target plate 4;

[0086] The position of the light spot left by the laser beam 22 on the second target disk is observed to detect the end deviation of the bellows 21 .

[0087] Specifically, the first target plate 4 and the second target plate are respectively installed at the two ends of the tested bellows 21 section through their installation grooves, so that the first target plate 4 and the second target plate are as perpendicular to the axis of the bellows 21 as possible to ensure the detection accuracy; then the support platform 1 can be placed on the steel plate bottom mold in the prestressed construction of the continuous beam, and the laser emitting component 3 is supported by the support frame. The device is laterally centered using the two limit rods 5 of the transverse centering structure, and the second pin holes at the ends of the two limit rods 5 are aligned with the first pin holes and the positioning pins 7 are inserted to ensure the transverse centering of the laser emitting component 3; then, the support feet are adjusted 2 can realize the leveling and height adjustment of the support platform 1, turn on the laser emitting component 3, ensure that the laser beam 22 emitted by the laser emitting component 3 is incident from the center of the first target plate 4, and the laser beam 22 is incident into the bellows 21 along the axis of the incident end of the bellows 21, and is emitted from the other end; when detecting the end deviation of the bellows 21, the position of the light spot left by the laser beam 22 on the second target plate can be observed at this time, and the deviation degree and deviation direction of the bellows 21 can be read in combination with the annular and cross scale lines on the second target plate, so as to facilitate the correction of the end position of the bellows 21 and improve the installation accuracy of the bellows 21.

[0088] Optionally, the outer diameters of the first target disk 4 and the second target disk are larger than the outer diameter of the bellows 21.

[0089] The support frame includes:

[0093] A suspension component 16, one end of the suspension component 16 is rotatably connected to the sliding shaft 14, and the other end of the suspension component 16 is connected to the laser emitting component 3;

[0096] The rotating ring 12 is rotated to make the laser beam 22 rotate outside the bellows 21 along the circumference thereof, so as to detect the deviation of the middle part of the bellows 21 .

[0097] Specifically, in order to further detect the offset of the middle part of the bellows 21, after detecting the offset of the end part of the bellows 21, the position of the device can be maintained, the position of the sliding shaft 14 can be adjusted, and the sliding shaft 14 can be moved outward along the guide groove 13, so that the laser beam 22 is on the outside of the bellows 21 and still passes through the first target plate 4 and the second target plate; then the rotating ring 12 can be rotated by the crank 20 to make the laser emitting component 3 and the laser beam 22 emitted by it move around the outer circumference of the bellows 21.
