Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a bridge prefabricated component installation and positioning device. Background Technology

[0002] In bridge engineering, prefabrication and assembly technology is often used to improve construction efficiency and quality. This involves dividing the bridge into several large components according to their structural composition, prefabricating these components in a factory or prefabrication yard, and then transporting them to the site for installation. When installing these components on the bridge, they need to be positioned to improve their stability after installation. Therefore, positioning devices are installed on the components to ensure accurate installation.

[0003] Chinese Patent Publication No. CN221956553U discloses a bridge precast component installation and positioning device, including a bridge support, a connector on the top of the bridge support, and a limiting component on the connector, the limiting component including two threaded rods installed on the top of the connector. This utility model can move two limiting rods simultaneously, reducing operation steps, and allows the limiting rods to quickly engage into the corresponding limiting holes, eliminating the need for workers to turn multiple handles, thereby improving the limiting efficiency of the connector.

[0004] While the aforementioned patent enables the two limiting rods to be adjusted synchronously during the installation and fixing of the connectors, thereby improving the installation efficiency of the connectors, it still requires continuous tightening of each threaded seat, which takes a considerable amount of time. The efficiency improvement is not significant, and it cannot achieve rapid fixing of the connectors during installation. There is still considerable room for improvement in installation efficiency.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a bridge prefabricated component installation and positioning device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A bridge precast component installation and positioning device includes a bridge bearing, a connecting groove on the surface of the bridge bearing, a positioning plate connected inside the connecting groove, a connector on the surface of the bridge bearing, a limiting plate connected to the surface of the connector, a casting groove inside the limiting plate, a limiting groove inside the casting groove, the limiting groove cooperating with the positioning plate, and a quick loading and unloading mechanism between the bridge bearing and the connector.

[0009] Furthermore, in order to achieve the effect of fixing the bridge bearing to the connector after installation, the quick loading and unloading mechanism includes multiple support rods connected to both sides inside the connecting groove, and a metal loading and unloading sleeve connected to the top of the support rod. The surface of the metal loading and unloading sleeve has a shrinkage groove.

[0010] Furthermore, in order to achieve rapid fixing of the connector to the bridge bearing, loading and unloading holes are opened on both sides of the surface of the connector, and a support cover is connected to the top of the metal loading and unloading sleeve, which cooperates with the loading and unloading holes.

[0011] Furthermore, in order to achieve the prefabrication and splicing of the bridge, prefabricated beams are provided on both sides of the connector, and the internal connections of the prefabricated beams are reinforced.

[0012] Furthermore, in order to achieve rapid connection between precast beams and connectors, positioning holes are opened on both sides of the casting groove, and the reinforcing bars are matched with the positioning holes.

[0013] Furthermore, in order to guide and position the precast beams during installation, guide blocks are connected to both sides of the connector.

[0014] Furthermore, to facilitate hoisting during the installation and fixing of the connectors, support grooves are provided on both sides of the limiting plate, and hoisting rings are connected inside the support grooves.

[0015] The beneficial effects of this utility model are as follows: Through the quick-release mechanism, when the connector needs to be installed on the surface of the bridge bearing, it can be lifted and transported into the connecting groove, and the positioning plate in the connecting groove can be installed in the limiting groove on the connector. At this time, the connector is gradually lowered. Simultaneously, the metal loading and unloading sleeve in the quick-release mechanism aligns with the positioning hole. Due to the weight of the connector as it is lowered, the metal loading and unloading sleeve contracts along the contraction groove, passes through the positioning hole, and then rebounds to its original position, thus achieving the limiting and fixing of the connector. This avoids the problem of repeated rotation of the threaded column and the long time consumption in the prior art, achieving rapid alignment and instant fixing of the connector, significantly shortening the installation cycle, further improving the installation efficiency of the connector on the bridge bearing, and facilitating the subsequent splicing and positioning of precast beams.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] According to an embodiment of the present invention, a bridge prefabricated component installation and positioning device is provided.

[0028] Example 1:

[0029] like Figures 1-5As shown, a bridge precast component installation and positioning device according to an embodiment of the present invention includes a concrete bridge bearing 1. The surface of the bridge bearing 1 has a connecting groove 2, and multiple pairs of positioning plates 3 are connected inside the connecting groove 2. A connector 4 is provided on the surface of the bridge bearing 1, and precast beams 9 are provided on both sides of the connector 4. Reinforcing ribs 10 are connected inside the precast beams 9. After the connector 4 is fixedly installed in the connecting groove 2 on the surface of the bridge bearing 1, it facilitates the casting and connection of the precast beams 9 inside, realizing rapid bridge assembly; the surface of the connector 4 is connected... A limiting plate 5 is connected, and a casting groove 6 is opened inside the limiting plate 5 for casting and fixing the two precast beams 9 after they are connected. A limiting groove 7 is opened inside the casting groove 6. The limiting groove 7 cooperates with the positioning plate 3. When the connector 4 is quickly installed with the bridge bearing 1, the positioning plate 3 and the limiting groove 7 cooperate to realize the quick positioning of the connector 4. A quick loading and unloading mechanism 8 is provided between the bridge bearing 1 and the connector 4 to instantly fix the connector 4 after positioning, so as to ensure the stability of the connector 4 installation and further improve the installation efficiency of the connector 4.

[0030] like Figures 1-7 As shown, the quick loading and unloading mechanism 8 includes multiple support rods 801 connected to both sides of the connecting groove 2. Each support rod 801 has a flat-topped conical metal loading and unloading sleeve 802 connected to its top. The surface of the metal loading and unloading sleeve 802 has a contraction groove 803. The surface of the connector 4 has loading and unloading holes 804 on both sides. The top of the metal loading and unloading sleeve 802 is connected to a support cover 805, which cooperates with the loading and unloading holes 804. When the connector 4 is lifted and positioned by the positioning plate 3 and the limiting groove 7, the loading and unloading holes 804 correspond to the support cover 805 and the metal loading and unloading sleeve 802. At this time, the lifted connector 4 is gradually lowered. After the support cover 805 passes through the loading and unloading hole 804, the connector 4 continues to move downward by its own weight. The loading and unloading hole 804 can apply pressure to the outside of the flat-topped conical metal loading and unloading sleeve 802, so that the metal loading and unloading sleeve 802 can move along... The shrinkage groove 803 shrinks and then smoothly passes through the loading and unloading hole 804. At this time, the metal loading and unloading sleeve 802, which has undergone elastic deformation and shrinkage, quickly rebounds and restores its original shape, thereby limiting and fixing the connector 4. Positioning holes 11 are opened on both sides of the casting groove 6. The reinforcing rib 10 cooperates with the positioning holes 11. When splicing two precast beams 9, the reinforcing rib 10 at one end is installed in the casting groove 6 through the positioning hole 11. By pouring concrete into the casting groove 6, the fixed connection of the two precast beams 9 after splicing is achieved. Guide blocks 12 are connected to both sides of the connector 4. When splicing precast beams 9, they guide the installation position of the connector 9 to facilitate the alignment of the reinforcing rib 10 with the positioning hole 11. Support grooves 13 are opened on both sides of the limiting plate 5. Lifting rings 14 are connected inside the support grooves 13 to tie the lifting rope to the lifting rings 14, so as to facilitate the lifting and handling of the connector 4 during installation.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, during the on-site assembly and construction of bridges, the connector 4 is first hoisted above the concrete bridge bearing 1. When the connector 4 is hoisted and lowered, its internal limiting groove 7 is aligned with the positioning plate 3 on the bridge bearing 1 and inserted into it, achieving preliminary and accurate positioning of the connector 4 in both horizontal and directional positions, effectively avoiding offset or misalignment during installation. As the connector 4 continues to fall to the predetermined position under the guidance of the positioning plate 3, the loading and unloading hole 804 gradually fits into the support cover 805 and presses against the conical outer surface of the metal loading and unloading sleeve 802. Because the metal loading and unloading sleeve 802 is elastic and has a shrinkage groove 803, it undergoes radial shrinkage after being squeezed by the edge of the loading and unloading hole 804, allowing it to pass smoothly through the loading and unloading hole 804. Once connector 4 has fully descended to its designed position, the metal loading / unloading sleeve 802 quickly rebounds due to its elasticity, and its enlarged outer diameter gets stuck above the loading / unloading hole 804, forming a solid limiting structure. This instantly locks connector 4 onto the bridge bearing 1, achieving rapid and reliable fixation. After completing the rapid positioning and locking of connector 4, two precast beams 9 are installed on both sides of connector 4. Reinforcing ribs 10 are pre-embedded inside the precast beams 9. During installation, the reinforcing rib 10 of one end of the precast beam 9 is inserted into the casting groove 6 in the middle of connector 4 through the positioning hole 11 on the limiting plate 5. The positioning hole 11 guides and positions the reinforcing rib 10, ensuring precise alignment of the reinforcing bar. Subsequently, concrete is poured into the casting groove 6 and cured, allowing the two precast beams 9 to be firmly connected as one piece through the cast-in-place section, achieving the overall splicing and installation of the bridge.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
