Description

Technical Field

[0001] This utility model relates to the field of bridge technology, and more specifically, to an auxiliary device for installing bridge beams and slabs. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, the term "bridge" has also been extended to refer to a structure erected to cross mountains, ravines, adverse geological conditions, or to meet other transportation needs, making travel more convenient. A bridge generally consists of a superstructure, substructure, supports, and auxiliary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. To ensure that bridge beams and slabs can be assembled quickly and effectively, auxiliary devices for bridge beam and slab installation are used.

[0003] A search revealed a prior art device for installing bridge beams, patent publication number CN222878519U. The specification states that it ensures accurate horizontal movement and docking of the main body of the bridge beam, thereby enabling rapid and efficient assembly of the main body. This avoids the torsion problem that occurs during docking of the main body of the bridge beam caused by traditional hoisting methods. Simultaneously, it prevents the main body of the bridge beam from tilting forward or backward during movement, ensuring that the right free end of the main body of the bridge beam remains straight, facilitating accurate docking between subsequent adjacent bridge beams. Furthermore, it ensures that the moving seat always moves accurately horizontally without tilting forward or backward or vertically.

[0004] However, in actual use, the pads will gradually wear down after a long period of use, making the clamping surface smoother, which reduces clamping stability and consequently reduces the installation stability of the bridge beams and slabs, making connection easier and affecting construction efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bridge beam installation auxiliary device to solve the problem that in the prior art, the pad will gradually wear down after long-term use, resulting in a smoother clamping surface, which reduces clamping stability, thereby reducing the installation stability of the bridge beam, reducing the ease of connection, and thus affecting construction efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bridge beam installation auxiliary device, including a body, two positioning plates are installed inside the body, two connecting grooves are opened inside the positioning plates, a connecting block is slidably connected inside the connecting groove, a pad is fixedly connected to the outside of the connecting block, the pad is slidably connected inside the positioning plate, a slot is opened on the inner wall of the connecting groove, a locking block is locked inside the slot, and the locking block is slidably connected inside the body through the connecting block.

[0007] The inner wall of the connecting groove has an installation groove on the other side. The end of the locking block away from the groove is fixedly connected to an installation piece. The end of the installation piece away from the locking block is fixedly connected to a pull rope. The end of the pull rope away from the installation piece is fixedly connected to a rotating rod. An elastic element is sleeved on the outside of the pull rope.

[0008] The positioning plate has a placement groove on the upper side of its inner wall. Two limiting blocks are fixedly connected to the inner wall of the placement groove. A groove is provided on the other side of the limiting block. A pull block is slidably connected to the top of the rotating rod. Two limiting grooves are provided on the outer side of the pull block. A protrusion is fixedly connected to the inner wall of the limiting groove.

[0009] The card block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, the pull rope is slidably connected inside the mounting groove, and the rotating rod is rotatably connected inside the positioning plate.

[0010] One end of the elastic element is fixedly connected to the inner wall of the pull rope, and the other end of the elastic element is fixedly connected to the mounting plate.

[0011] The pull block is slidably connected inside the placement groove, and the pull block slides against the outside of the limiting block.

[0012] The limiting block is fitted with the inside of the limiting groove, and the protrusion is fitted with the inside of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, the pad is slidably installed inside the positioning plate and engaged with a locking block, which makes the pad easy to install and remove, resulting in high replacement efficiency.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a bridge beam installation auxiliary device, including a body 1. Two positioning plates 2 are installed inside the body 1. Two connecting grooves 18 are opened inside the positioning plates 2. Connecting blocks 3 are slidably connected inside the connecting grooves 18, and the connecting grooves 18 provide installation space for the connecting blocks 3. A pad 6 is fixedly connected to the outside of the connecting blocks 3. The pad 6 is slidably connected inside the positioning plates 2, and the positioning plates 2 provide installation space for the pad 6. A slot 4 is opened on the inner wall of the connecting grooves 18. A locking block 5 is locked inside the slot 4. The locking block 5 passes through the connecting block 3 and is slidably connected inside the body 1, so that the connecting block 3 can be limited, thereby limiting the positioning plates 2.

[0025] When the pad 6 needs to be replaced, the two locking blocks 5 are moved to the same side, so that the locking blocks 5 can be disengaged from the inside of the locking slot 4 and slide into the inside of the body 1. At this time, the connecting block 3 is no longer restricted, and the pad 6 is pulled so that the pad 6 can be disengaged from the inside of the positioning plate 2. Conversely, installation can be carried out conveniently.

[0026] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 5, an installation groove 7 is provided on the other side of the inner wall of the connecting groove 18. The locking block 5 is slidably connected to the inside of the installation groove 7, which provides installation space for the locking block 5. An installation piece 8 is fixedly connected to the end of the locking block 5 away from the locking groove 4. The installation piece 8 is slidably connected to the inside of the installation groove 7, which limits the installation piece 8 so that it will not deviate when sliding. A pull rope 9 is fixedly connected to the end of the installation piece 8 away from the locking block 5, which is slidably connected to the inside of the installation groove 7. A rotating rod 11 is fixedly connected to the end of the pull rope 9 away from the installation piece 8. The rotating rod 11 is rotatably connected to the inside of the positioning plate 2, which limits the rotating rod 11 so that it can rotate smoothly. An elastic element 10 is sleeved on the outside of the pull rope 9. One end of the elastic element 10 is fixedly connected to the inner wall of the pull rope 9, and the other end is fixedly connected to the installation piece 8.

[0027] When the locking block 5 needs to be pulled, the rotating rod 11 is rotated so that one end of the pull rope 9 is wound around it, so that the pull rope 9 pulls the mounting piece 8 to move inward, thereby causing the mounting piece 8 to compress the elastic element 10 and deform, and pulling the locking block 5 into the interior of the mounting groove 7. Conversely, by releasing the rotating rod 11, the elastic element 10 is reset, thereby causing the elastic element 10 to push the mounting piece 8 to move outward, thereby causing the mounting piece 8 to pass through the connecting block 3 and engage with the interior of the locking groove 4.

[0028] Example 3: Based on Example 2, in order to limit the rotation rod 11, a placement groove 15 is provided on the upper side of the inner wall of the positioning plate 2. Two limiting blocks 16 are fixedly connected to the inner wall of the placement groove 15. A groove 17 is provided on the other side of the limiting block 16. A pull block 12 is slidably connected to the top of the rotation rod 11. The sliding part of the pull block 12 and the rotation rod 11 is a rectangular block structure, so that the pull block 12 can drive the rotation rod 11 to rotate. The pull block 12 is slidably connected inside the placement groove 15, which provides installation space for the pull block 12. The pull block 12 slides against the outside of the limiting block 16, so that the pull block 12 can squeeze the limiting block 16 to produce deformation. Two limiting grooves 13 are provided on the outside of the pull block 12. The limiting block 16 fits into the inside of the limiting groove 13, so that the pull block 12 is limited. A protrusion 14 is fixedly connected to the inner wall of the limiting groove 13. The protrusion 14 fits into the inside of the groove 17, so that the pull block 12 is limited again.

[0029] When the rotating rod 11 needs to be rotated, the pull block 12 is pulled upwards, causing it to slide against the limiting block 16. This causes the limiting block 16 to deform, allowing the pull block 12 to disengage from the inside of the placement groove 15. At this time, rotating the pull block 12 causes the rotating rod 11 to rotate. Conversely, by sliding the pull block 12 into the placement groove 15, the pull block 12 is squeezed against the limiting block 16 again, causing it to deform. When the pull block 12 is in contact with the inner wall of the placement groove 15, the limiting block 16 is reset, allowing it to fit inside the limiting groove 13 and the protrusion 14 to fit inside the groove 17, thus limiting the pull block 12.

[0030] The working process of this utility model is as follows:

[0031] When the pad 6 needs to be installed, by pulling the pull block 12 upward, the pull block 12 slides against the limiting block 16, causing the limiting block 16 to deform and allowing the pull block 12 to disengage from the inside of the placement groove 15. Then, by rotating the pull block 12, the pull block 12 drives the rotating rod 11 to rotate, causing the rotating rod 11 to wind around one end of the pull rope 9, pulling the mounting piece 8 inward. This causes the mounting piece 8 to compress the elastic element 10, deforming it and pulling the locking block 5 into the inside of the installation groove 7. By sliding the pull block 12 into the placement groove 15, the pull block 12 compresses the limiting block 16 again, causing deformation. When the pull block 12 is in contact with the inner wall of the placement groove 15, the limiting block 16 returns to its original position, fitting inside the limiting groove 13. The protrusion 14 fits into the interior of the groove 17, thereby limiting the pull block 12. At this time, the pad 6 can be slid into the interior of the positioning plate 2, allowing the connecting block 3 to slide into the interior of the connecting groove 18. Then, the pull block 12 is pulled upward again to disengage from the interior of the placement groove 15. By releasing the pull block 12, the elastic element 10 can perform a reset movement, thereby pushing the mounting piece 8 to move outward. This allows the mounting piece 8 to pass through the connecting block 3 and engage with the interior of the slot 4. Then, the pull block 12 is slid into the interior of the placement groove 15 again, thereby limiting the rotating rod 11 again. This allows the pad 6 to be stably installed inside the positioning plate 2, making it easy to install and remove the pad 6, resulting in high replacement efficiency. This does not affect the docking efficiency and quality of the bridge beams, making it highly economical to use.
