Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically a hoisting bracket for arch rib installation. Background Technology

[0002] Arch ribs are the main load-bearing structures of arch bridges. They are mostly arc-shaped or zigzag-shaped, resisting loads and transferring forces to the foundation through their own bending. Their materials are often steel, concrete, or steel-concrete composites. Their shape and size need to be designed in conjunction with the bridge span and stress requirements. As the "skeleton" of the arch bridge, the stability of the arch ribs directly affects the overall safety of the bridge. Precise control of assembly or pouring accuracy is required during construction.

[0003] Before hoisting the arch rib, appropriate lifting tools and equipment should be selected based on parameters such as structural weight and span. The hoisting points should be reinforced to ensure balanced force. During the hoisting process, the arch rib should be slowly lifted by the lifting equipment, and the arch rib should be precisely adjusted with the traction device to gradually approach the installation position. After the arch rib is accurately aligned, it should be temporarily fixed and the hoisting status should be monitored in real time. After confirming stability, the final placement should be completed to ensure installation accuracy and safety.

[0004] When installing the arch ribs, they are hoisted in sections and moved to the installation position one by one. During hoisting, both ends are lifted and then moved to the installation position. However, the two ends are connected by hooks, resulting in less contact and affecting the stability during hoisting.

[0005] Therefore, a hoisting bracket for arch rib installation is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The utility model provides a hoisting bracket for arch rib installation, including a bracket body. Multiple sliding grooves are provided on the top side wall of the bracket body. A slider is slidably connected inside the sliding groove. A bolt is threadedly connected to the middle of the slider. A clamping plate is rotatably connected to the end of the bolt. The clamping plate has an arc-shaped middle section. Multiple lifting rings are fixedly connected to the top of the bracket body. The lifting rings are located at the four corners of the bracket body. By adding clamping plates, the arch rib can be clamped and fixed during placement. Subsequently, during hoisting of the arch rib, the force is evenly distributed through the distribution of the lifting rings, thereby increasing the stability when the arch rib is hoisted.

[0008] Preferably, a plurality of spring telescopic rods are fixedly connected to the middle of the support body; a push plate is fixedly connected to the top of the spring telescopic rods; by adding the push plate, when the arch rib is placed inside the support body, the push plate is pushed to contact the arch rib by the thrust generated by the pressure of the spring telescopic rods. When in contact, the contact between the middle of the arch rib and the support body is increased, thereby increasing the stability of the arch rib after it is fixed inside the support body.

[0009] Preferably, a flexible ball is fixedly connected to the middle of the push plate; the flexible ball and the push plate are correspondingly arranged; by adding the flexible ball, the contact area between the push plate and the arch rib can be increased by the deformation of the flexible ball when they come into contact, and the flexibility of the flexible ball can also reduce the hard friction when they come into contact, thereby increasing the protection when they come into contact.

[0010] Preferably, a friction pad is fixed to the surface of the lifting ring; the friction pad and the lifting ring are correspondingly arranged; by increasing the friction pad, the hook can be inserted into the friction pad when under force, thereby increasing the contact area when lifting, and thus increasing the movement resistance.

[0011] Preferably, multiple elastic cloths are fixedly connected to the top of the bracket body; the ends of the elastic cloths and the push plate are fixedly connected; by adding elastic cloths, the spring telescopic rod can be protected, reducing the contact between dust and the spring telescopic rod, thereby reducing the damage of dust to the spring telescopic rod.

[0012] Preferably, an arc-shaped plate is fixed to the end of the bracket body; multiple arc-shaped plates are provided on the bracket body; by adding arc-shaped plates, the arc shape of the arc-shaped plate surface can be used to increase the fit when it contacts the arch rib, thereby reducing damage when it contacts it.

[0013] The advantages of this utility model are:

[0014] 1. The hoisting bracket for arch rib installation described in this utility model can clamp and fix the arch rib when it is placed by adding clamping plates. Then, when the arch rib is hoisted, the force is evenly distributed by the distribution of the lifting rings, thereby increasing the stability when the arch rib is hoisted.

[0015] 2. The hoisting bracket for arch rib installation described in this utility model, by adding a push plate, can push the push plate to contact the arch rib when the arch rib is placed inside the bracket body by the thrust generated by the pressure of the spring telescopic rod. After contact, the contact between the middle of the arch rib and the bracket body will be increased, thereby increasing the stability of the arch rib after it is fixed inside the bracket body.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a hoisting bracket for installing an arch rib includes a bracket body 1. Multiple sliding grooves 15 are formed on the top side wall of the bracket body 1. A slider 11 is slidably connected inside each sliding groove 15. A bolt 12 is threadedly connected to the middle of each slider 11. A clamping plate 13 is rotatably connected to the end of the bolt 12. The clamping plate 13 has an arc-shaped middle section. Multiple lifting rings 14 are fixedly connected to the top of the bracket body 1. The lifting rings 14 are located at the four corners of the bracket body 1. During operation, when hoisting the arch rib, a section of the arch rib is first placed in the middle of the bracket body 1. Because the middle section of the arch rib has an arc shape, the inner wall will contact the end of the bracket body 1 when placed inside. At this time, the clamping plate 13 and the side wall of the arch rib can be aligned. Then, rotate bolt 12. As it rotates, bolt 12 will gradually push clamping plate 13 towards the arch rib. After contact, it will gradually compress and clamp the arch rib through the clamping plates 13 at both ends. The curved shape of clamping plate 13 allows for a more snug fit. Once snug, the arch rib will be fixed. After fixing, the hook and multiple lifting rings 14 can be brought into contact. Then, they can be aligned and lifted. When lifting, the lifting rings 14 are located at the four corners, providing a more stable placement platform for the arch rib. By adding clamping plates 13, the arch rib can be clamped and fixed during placement. Then, when lifting the arch rib, the force is evenly distributed through the distribution of lifting rings 14, thereby increasing the stability when lifting the arch rib.

[0026] like Figures 1 to 3 As shown, multiple spring telescopic rods 2 are fixedly connected to the middle of the support body 1; a push plate 21 is fixedly connected to the top of the spring telescopic rod 2; during operation, when the arch rib is placed inside the support body 1, the inner wall will first contact the push plate 21, and then the push plate 21 will move down. During the downward movement, the spring telescopic rod 2 will be compressed, so that it will still push the push plate 21 to contact the inner wall of the arch rib when compressed. When in contact, the push plate 21 will fit with the arch rib, thereby increasing the middle support of the arch rib inside the support body 1; by adding the push plate 21, when the arch rib is placed inside the support body 1, the push plate 21 can be pushed to contact the arch rib by the thrust generated by the pressure of the spring telescopic rod 2. When in contact, the contact between the middle of the arch rib and the support body 1 will be increased, thereby increasing the stability of the arch rib after it is fixed inside the support body 1.

[0027] like Figures 2 to 3As shown, a flexible ball 3 is fixedly connected to the middle of the push plate 21; the flexible ball 3 and the push plate 21 are correspondingly arranged; during operation, when the push plate 21 is pushed towards the arch rib by the spring telescopic rod 2, the flexible ball 3 will first contact the arch rib. During contact, the flexible ball 3 will gradually deform, and during deformation, it will gradually flatten to increase the contact area with the arch rib. At the same time, it can also increase flexible isolation during contact, thereby reducing hard contact during long-term contact; by adding the flexible ball 3, the contact area between the push plate 21 and the arch rib can be increased by the deformation of the flexible ball 3 when they contact each other. At the same time, the flexibility of the flexible ball 3 can also reduce hard friction when they contact each other, thereby increasing protection during contact.

[0028] like Figures 1 to 4 As shown, a friction pad 4 is fixedly attached to the surface of the lifting ring 14; the friction pad 4 and the lifting ring 14 are correspondingly arranged; during operation, when the hook and the lifting ring 14 come into contact, the hook will first contact the friction pad 4. As the force increases, the friction pad 4 will be gradually squeezed. During the squeezing, it will deform and thus sink the hook into the friction pad 4, thereby increasing the wrapping effect; by increasing the friction pad 4 so that the hook can sink into the friction pad 4 when subjected to force, the contact area is increased when lifting, thereby increasing the movement resistance.

[0029] like Figures 2 to 3 As shown, multiple elastic cloths 5 are fixedly connected to the top of the bracket body 1; the ends of the elastic cloths 5 and the push plate 21 are fixedly connected; during operation, since the installation environment of the arch rib is outdoors, the dust in the surrounding environment will be blocked by the elastic cloths 5 when it is moving during installation; by adding elastic cloths 5, the spring telescopic rod 2 can be protected, reducing the contact between dust and the spring telescopic rod 2, thereby reducing the damage of dust to the spring telescopic rod 2.

[0030] like Figures 1 to 3 As shown, an arc-shaped plate 6 is fixed to the end of the support body 1; multiple arc-shaped plates 6 are provided on the support body 1; during operation, when the inner wall of the arch rib contacts the support body 1, the arc-shaped plate 6 will be located between the arch rib and the support body 1. At this time, the arc-shaped plate 6 will fit against the inner wall of the arch rib through the arc shape of its surface, so that the contact between the sharp corners and the inner wall of the arch rib is reduced after placement; by adding arc-shaped plates 6, the arc shape of the surface of the arc-shaped plate 6 can be used to increase the fit when it contacts the arch rib, thereby reducing damage when it contacts it.

[0031] Working principle: When hoisting the arch rib, first place a section of the arch rib in the middle of the support body 1. Because the middle of the arch rib is curved, the inner wall will contact the end of the support body 1 when it is placed inside. At this time, the clamping plate 13 can be aligned with the side wall of the arch rib, and then the bolt 12 can be rotated. After rotation, the bolt 12 will gradually push the clamping plate 13 to contact the arch rib. After contact, it will gradually squeeze and clamp and fix it through the clamping plates 13 at both ends. At the same time, the clamping plate 13 is curved, which can fix it more closely. After contact, the arch rib will be fixed. After fixing, the hook and multiple lifting rings 14 can be contacted, and then aligned and lifted. When lifting, the lifting rings 14 are located at the four corners, which can provide a more stable placement platform for the arch rib. When the arch rib is placed inside the support body 1, the inner wall will first contact the push plate 21, and then the push plate 21 will move down. During the downward movement, the spring telescopic rod 2 will be compressed, so that it still pushes the push plate 21 to contact the inner wall of the arch rib during compression. When in contact, the push plate 21 will fit against the arch rib, thereby increasing the central support of the arch rib inside the bracket body 1. When the push plate 21 is pushed towards the arch rib by the spring telescopic rod 2, the flexible ball 3 will first contact the arch rib. During contact, the flexible ball 3 will gradually deform and gradually flatten to increase the contact area with the arch rib. At the same time, it can also increase flexible isolation during contact, thereby reducing hard contact during long-term contact. When the hook and the lifting ring 14 contact, they will first contact the friction pad 4. As the force increases, the friction pad 4 will be gradually squeezed. During the squeezing, it will deform and sink the hook into the friction pad 4, thereby increasing the wrapping. Since the arch rib is installed outdoors, the dust in the surrounding environment will be blocked by the elastic cloth 5 when it is moving during installation. When the inner wall of the arch rib contacts the bracket body 1, the arc plate 6 will be located between the arch rib and the bracket body 1. At this time, the arc plate 6 will fit against the inner wall of the arch rib through the arc shape of its surface, so that the contact between the sharp corners and the inner wall of the arch rib is reduced after placement.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
