Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a device for adjusting and positioning the width of a pre-reserved groove for bridge expansion joints. Background Technology

[0002] Bridge expansion joints, as a key component of bridge structures, play a vital role in ensuring bridge structural safety, accommodating thermal expansion and contraction, and ensuring smooth and comfortable driving. With the continuous development of my country's transportation infrastructure construction, especially the large-scale construction of long-span bridges and urban viaducts, higher requirements have been placed on the construction precision and quality of bridge expansion joints.

[0003] While the research and development of expansion joint devices themselves is relatively mature in the industry, there is still room for improvement in the construction and positioning technology of the expansion joint pre-reserved groove. The construction quality of the pre-reserved groove directly affects the installation accuracy and performance of the expansion joint device later.

[0004] Traditional construction methods typically involve manually visually inspecting the width of expansion joints. Lacking specialized tools, this leads to inconsistent accuracy. With traditional timber reinforcement, the width deviation can reach 2-3 cm, severely impacting the quality of subsequent expansion joint installation. Furthermore, existing technologies have limitations in on-site width adjustment, failing to adapt flexibly to changes in on-site temperature and the actual bridge joint width. This often necessitates extensive on-site modifications and customization during installation, increasing construction difficulty and costs.

[0005] To address this issue, a bridge expansion joint pre-reserved groove width adjustment and positioning device is proposed. Summary of the Invention

[0020] The present invention discloses the following technical effects:

[0021] 1.

[0024] IV.

Then, the lower biting mechanism is positioned by the positioning mechanism to prevent the lower biting mechanism from moving. In this way, the distance between template one and template two can be effectively guaranteed.

[0025] Fifth, when working on bridge expansion joints, this invention can not only precisely adjust the distance between template one and template two, but also fix template one and template two to prevent the size of the expansion joint from changing during the operation.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figure 1-6 This invention provides a bridge expansion joint reserved groove width adjustment and positioning device, comprising:

[0037] Base plate 1, with two sets of displacement devices on the bottom surface of base plate 1, and a sliding plate 2 fixedly connected to the displacement device, the sliding plate 2 being located on the top surface of base plate 1;

[0038] Template 1 3 and Template 2 4 are respectively set on two sliding plates 2 by locking mechanisms. Template 1 3 is equipped with a lifting mechanism, and Template 2 4 is equipped with a positioning mechanism. Both Template 1 3 and Template 2 4 are equipped with laser rangefinders 5.

[0039] The fixing component includes an upper biting mechanism and a lower biting mechanism. The upper biting mechanism is mounted on the lifting mechanism, and the lower biting mechanism is mounted on the template 2 4. The positioning mechanism is used to position the lower biting mechanism and abuts against the lower biting mechanism.

[0040] In this device, when pouring the expansion joint of the bridge, the base plate 1 is first fixed below the designed position of the expansion joint. Then, template 3 and template 4 are respectively installed on two sliding plates 2 through locking mechanisms. The sliding plates 2 are moved by displacement devices to adjust the distance between template 3 and template 4. Template 3 and template 4 can be moved independently, making the adjustment more convenient. After the distance between template 3 and template 4 is adjusted using a laser rangefinder 5, the upper and lower interlocking mechanisms are used to fix the position between template 3 and template 4 to prevent the distance between template 3 and template 4 from changing during the pouring process and to prevent template 3 and template 4 from tilting, making the expansion joint size more accurate. After the distance between template 3 and template 4 is determined, the upper interlocking mechanism is lowered by a lifting mechanism to make the upper interlocking mechanism and the lower interlocking mechanism interlock together. Then, the lower interlocking mechanism is positioned by a positioning mechanism to prevent the lower interlocking mechanism from moving. In this way, the distance between template 3 and template 4 can be effectively guaranteed.

[0041] The scheme is further optimized. The lower biting mechanism includes a first fixed plate 6. A first cavity 7 is opened in the first fixed plate 6. A first through hole 8 and a second through hole 9 are connected to the first cavity 7. The first through hole 8 is located above the first cavity 7, and the second through hole 9 is located below the first cavity 7. A first inner plate 10 is slidably arranged in the first cavity 7. A plurality of first biting teeth 11 are fixedly connected to the first inner plate 10. The plurality of first biting teeth 11 are equidistant from each other and extend out of the first through hole 8.

[0042] The first inner plate 10 can move within the first cavity 7. A plurality of first biting teeth 11 are arranged at equal intervals on the first inner plate 10. The first biting teeth 11 are used to cooperate with the upper biting mechanism. When the first biting teeth 11 are engaged with the upper biting mechanism, the distance between template 1 3 and template 2 4 can be prevented from changing, and template 1 3 and template 2 4 can also be prevented from tilting or falling over. The length of the first inner plate 10 is less than the length of the first cavity 7, and the first inner plate 10 can slide in the first cavity 7.

[0043] The scheme is further optimized. The positioning mechanism includes a first mounting plate 12 and a second mounting plate 13. Both the first mounting plate 12 and the second mounting plate 13 are fixedly connected to the template 4. The first mounting plate 12 is located above the second mounting plate 13. A first electric telescopic rod 14 is fixedly connected to the first mounting plate 12, and a second electric telescopic rod 15 is fixedly connected to the second mounting plate 13. A first blocking mechanism is provided between the first electric telescopic rod 14 and the first inner plate 10, and a second blocking mechanism is provided between the second electric telescopic rod 15 and the first inner plate 10. The first blocking mechanism and the second blocking mechanism are used to prevent the first inner plate 10 from sliding in the first cavity 7.

[0044] The first mounting plate 12 is used to install the first electric telescopic rod 14. The first electric telescopic rod 14 drives the first blocking mechanism to move, thereby achieving initial fixation of the first inner plate 10. The second mounting plate 13 is used to install the second electric telescopic rod 15. The second electric telescopic rod 15 drives the second blocking mechanism to achieve complete fixation of the first inner plate 10.

[0045] The scheme is further optimized. The first blocking mechanism includes a first blocking block 16 and a second blocking block 17. The first blocking block 16 is fixedly connected to the output end of the first electric telescopic rod 14, and the second blocking block 17 is fixedly connected to the first inner plate 10. The first blocking block 16 extends out of the first through hole 8. A first support plate 18 is fixedly connected to the template 4. A first guide hole is opened on the first support plate 18. The first blocking block 16 is located in the first guide hole. The first blocking block 16 has a first inclined surface 19, and the second blocking block 17 has a second inclined surface 20. The first inclined surface 19 and the second inclined surface 20 abut against each other.

[0046] The first electric telescopic rod 14 extends or retracts, causing the first blocking block 16 to move up and down. After the first biting tooth 11 engages with the upper biting mechanism, the position of the first inner plate 10 does not need to be changed. The first electric telescopic rod 14 extends, and the first blocking block 16 moves towards the second blocking block 17 until the ground slope 19 contacts the second slope 20. Figure 3 It can be seen that the first inner plate 10 can no longer move to the left, thus the first inner plate 10 is initially fixed.

[0047] The scheme is further optimized. The second blocking mechanism includes a third blocking block 21 and a fourth blocking block 22. The third blocking block 21 is fixedly connected to the output end of the second electric telescopic rod 15. The fourth blocking block 22 is fixedly connected to the bottom surface of the first inner plate 10 and extends out from the second through hole 9. A second support plate 23 is fixedly connected to the template 2 4. A second guide hole is opened on the second support plate 23. The third blocking block 21 is located in the second guide hole. The third blocking block 21 has a third inclined surface 24. The fourth blocking block 22 has a fourth inclined surface 25. The third inclined surface 24 and the fourth inclined surface 25 abut against each other. The second inclined surface 20 and the fourth inclined surface 25 are parallel.

[0048] The second electric telescopic rod 15 extends or retracts, causing the third blocking block 21 to move up and down. After the first biting tooth 11 engages with the upper biting mechanism, the position of the first inner plate 10 does not need to be changed. The second electric telescopic rod 15 extends, and the third blocking block 21 moves towards the fourth blocking block 22 until the third inclined surface 24 and the fourth inclined surface 25 contact each other. Figure 3 It can be seen that the first inner plate 10 can no longer move to the right, thus completely fixing the first inner plate 10, and the first inner plate 10 cannot continue to move within the first cavity 7.

[0049] The scheme is further optimized. The upper biting mechanism includes a second fixed plate 26. Several second biting teeth 27 are fixedly connected to the second fixed plate 26. The second biting teeth 27 are located above the first biting teeth 11. The second fixed plate 26 is set on the lifting mechanism.

[0050] The distance between two adjacent second occlusal teeth 27 is the same as the distance between two adjacent first occlusal teeth 11, so that the second occlusal teeth 27 can enter between the first occlusal teeth 11, realizing the mutual biting of the first occlusal teeth 11 and the second occlusal teeth 27.

[0051] The structures of the second occlusal tooth 27 and the first occlusal tooth 11 are as follows: Figure 3 As shown, the tops are all triangular, which facilitates interlocking during engagement.

[0052] The scheme is further optimized. The lifting mechanism includes a third fixed plate 28, a second cavity 29 is opened in the third fixed plate 28, the second cavity 29 is connected to a third through hole, a second inner plate 30 is slidably arranged in the second cavity 29, a first threaded rod 31 is rotatably arranged in the second cavity 29, a first motor 32 is fixedly connected to the template 3, the drive shaft of the first motor 32 is fixedly connected to the first threaded rod 31, the second inner plate 30 is opened with a first threaded hole, the first threaded rod 31 is threadedly connected in the first threaded hole, and the second fixed plate 26 is fixedly connected to the second inner plate 30.

[0053] The first motor 32 drives the first threaded rod 31 to rotate. When the first threaded rod 31 rotates, it drives the second inner plate 30 to move within the second cavity 29, thereby causing the second inner plate 30 to drive the second fixed plate 26 to move, thus realizing the up and down movement of the second meshing teeth 27.

[0054] Further optimization of the scheme: the displacement device includes a second motor 33, which is fixedly connected to the bottom surface of the base plate 1. A third support plate 34 is fixedly connected to the bottom surface of the base plate 1. A second threaded rod 35 is fixedly connected to the drive shaft of the second motor 33. The end of the second threaded rod 35 away from the second motor 33 is rotatably connected to the third support plate 34. A first elongated hole 36 and two second elongated holes are provided on the base plate 1. A slider 37 is slidably arranged in the first elongated hole 36. A second threaded hole is provided on the slider 37. The second threaded rod 35 is threadedly connected to the threaded hole. A sliding plate 2 is fixedly connected to the slider 37. Two limiting plates 38 are fixedly connected to the sliding plate 2. The limiting plates 38 are slidably arranged in the second elongated holes.

[0055] The second motor 33 drives the second threaded rod 35 to rotate. When the second threaded rod 35 rotates, it drives the slider 37 to move. When the slider 37 moves, it drives the sliding plate 2 to move. This makes it convenient to adjust the distance between the template 1 3 and the template 2 4. The limiting plate 38 is located in the second elongated hole, which makes the movement of the sliding plate 2 more stable. The width of the first elongated hole 36 is greater than the width of the slider 37 to prevent jamming.

[0056] The locking mechanism is further optimized by including several connecting plates 39, which are fixedly connected to template 1 3 and template 2 4 respectively. Several positioning posts 40 are fixedly connected to the sliding plate 2. The connecting plates 39 have insertion holes, and the positioning posts 40 are inserted into the insertion holes. The positioning posts 40 have annular grooves 41. A third cavity is formed inside the connecting plates 39. An arc-shaped retaining ring 42 is slidably arranged in the third cavity. The arc-shaped retaining ring 42 is adapted to the annular groove 41. A third motor 43 is fixedly connected to the outside of the connecting plates 39. A third threaded rod 44 is fixedly connected to the drive shaft of the third motor 43. The third threaded rod 44 extends into the third cavity. A third threaded hole 45 is formed on the arc-shaped retaining ring 42, and the third threaded rod 44 is threadedly connected to the third threaded hole 45.

[0057] When installing template 1 3 and template 2 4, insert the positioning post 40 into the insertion hole of the connecting plate 39, and then start the third motor 43. The third motor 43 drives the third threaded rod 44 to rotate. The rotation of the third threaded rod 44 will drive the arc-shaped retaining ring 42 to move, so that the arc-shaped retaining ring 42 enters the annular retaining groove 41, thereby realizing the connection between the connecting plate 29 and the positioning post 40.

[0058] In a further optimized design, springs 46 are fixedly connected to both ends of the first inner plate 10. The springs 46 are fixedly connected to the inner wall of the first cavity 7. Two third mounting plates 47 are fixedly connected to the bottom plate 1. Several mounting holes 48 are provided on the third mounting plates 47.

[0059] Spring 46 facilitates the return of the first inner plate 10 to its original position, and the third mounting plate 47 and mounting hole 48 facilitate the installation of the base plate 1.

[0060] The method of using this device is as follows: When pouring the expansion joint of a bridge, first fix the base plate 1 below the designed position of the expansion joint, connect the third mounting plate 47 and mounting hole 48 together with other facilities, then install the template 1 3 and template 2 4 on the two sliding plates 2 respectively, insert the positioning column 40 into the insertion hole of the connecting plate 39, then start the third motor 43, the third motor 43 drives the third threaded rod 44 to rotate, the rotation of the third threaded rod 44 will drive the arc-shaped retaining ring 42 to move, so that the arc-shaped retaining ring 42 enters the annular retaining groove 41, thereby realizing the connection between the connecting plate 29 and the positioning column 40;

[0061] Start the second motor 33, which drives the second threaded rod 35 to rotate. When the second threaded rod 35 rotates, it drives the slider 37 to move. When the slider 37 moves, it drives the sliding plate 2 to move, thereby adjusting the distance between template 1 3 and template 2 4. The distance between template 1 3 and template 2 4 is measured using a laser rangefinder 5. After the distance between template 1 3 and template 2 4 is adjusted, start the first motor 32, which drives the first threaded rod 31 to rotate. The first threaded rod 31 drives the second inner plate 30 to move. The second inner plate 30 drives the second fixed plate 26 and the second biting tooth 27 to move downwards until the second biting tooth 27 enters between the first biting tooth 11. When the second biting tooth 27 and the first biting tooth 11 are engaged, the first inner plate 10 will move a short distance. After the second biting tooth 27 and the first biting tooth 11 are fully engaged, the first inner plate 10 will no longer move.

[0062] Activate the first electric telescopic rod 14, which extends and moves the first blocking block 16 toward the second blocking block 17 until the ground slope 19 contacts the second slope 20, thus initially fixing the first inner plate 10. Activate the second electric telescopic rod 15, which extends and moves the third blocking block 21 toward the fourth blocking block 22 until the third slope 24 contacts the fourth slope 25, thus completely fixing the first inner plate 10. Then, the pouring operation can be carried out.
