Description

Technical Field

[0001] This utility model relates to the field of bridge pier support technology, and in particular to a railway bridge pier support installation device. Background Technology

[0002] Bridge pier bearings are key components connecting the superstructure of a bridge to the lower pier. Their main function is to safely and effectively transfer the load of the superstructure to the lower pier structure, while ensuring that the superstructure can deform freely under the influence of load, temperature changes, concrete shrinkage and creep.

[0003] When installing bridge bearings, the loose sand on the top surface of the pier pad stone must be removed first. The top surface of the pier should be clean, flat and free of oil stains. However, the top surface of the pier pad stone is relatively large, which is very inconvenient to clean, thus affecting the installation efficiency of the bridge bearings.

[0004] The existing patent (publication number: CN220579817U) discloses a highway bridge bearing installation device. When cleaning is required, the motor is started to drive the first moving block to move, which simultaneously drives the support rod and cleaning brush to move inside the mounting frame, so that the cleaning brush contacts the top surface of the pier and cleans the top surface of the pier. When the support rod moves, the gear at one end of the support rod meshes with the toothed plate, which allows the support rod to rotate on one side of the first moving block. This causes the support rod to drive the cleaning brush to rotate synchronously, which can improve the cleaning effect of the cleaning brush and make the cleaning more thorough.

[0005] To address the aforementioned issues, existing patents offer solutions. However, some existing patents do not adequately consider fine-tuning capabilities during the installation of railway bridge pier supports. Some simple hoisting equipment merely places the supports roughly in a predetermined position on the railway bridge pier without being equipped with precise adjustment devices. In such cases, once the supports are in place, changing their position becomes extremely difficult. When the supports are heavy, it is difficult for construction workers to accurately adjust their position after placement using manual handling and simple tools, which affects the accuracy of the railway bridge pier support installation.

[0006] To address this, a railway bridge pier support installation device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a railway bridge pier support installation device that solves the problem that some existing railway bridge pier support installation devices do not fully consider fine-tuning functions. Some simple hoisting devices simply place the support roughly in a predetermined position on the railway bridge pier without being equipped with a fine adjustment device. In this case, once the support is placed in place, it becomes very difficult to change the position of the support. When the support is heavy, it is difficult for construction workers to make precise adjustments to its position after placement using manual handling and simple tools, which affects the installation accuracy of the railway bridge pier support.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a railway bridge pier support installation device, comprising a pier body, a pad stone and a support body, wherein a fixing ring is fitted on the surface of the pier body, a pushing fine-tuning mechanism is provided on the top of the fixing ring, and a limit mechanism is provided on both sides of the bottom of the fixing ring.

[0009] The push fine-tuning mechanism includes an anti-slip pad, a push plate, an electric telescopic rod, and a slide. The left side of the anti-slip pad is fixedly connected to the right side of the push plate, the right side of the telescopic end of the electric telescopic rod is fixedly connected to the left side of the push plate, and the left side of the electric telescopic rod is fixedly connected to the right side of the slide.

[0010] Preferably, the limiting mechanism includes a clamping plate, a bearing, a rotating column, and an internal hexagonal screw head. The outer wall of the bearing is fixedly connected to the clamping plate on the side closest to the clamping plate. The surface of the rotating column is fixedly connected to the inner wall of the bearing. The internal hexagonal screw head is fixedly connected to the rotating column on the side closest to the rotating column.

[0011] Preferably, both sides of the bottom of the fixing ring are fixedly connected to fixing plates, and the rotating column is threadedly connected inside the fixing plates.

[0012] Preferably, a limiting cone is fixedly connected to one side of each of the two clamping plates. The limiting cones are a number and are evenly distributed on the surface of the clamping plates. The surface of the limiting cones is in close contact with the surface of the pier body.

[0013] Preferably, the fixing ring has an annular groove inside, and the slide is slidably connected inside the annular groove.

[0014] Preferably, pull rings are fixedly connected to both the front and rear sides of the carriage.

[0015] Preferably, a limiting ring is fixedly connected to the top of the fixing ring, and the bottom of the fixing ring is in contact with the top of the pier body.

[0016] Preferably, the surface of the fixing ring is fixedly connected with four hooks, which are evenly distributed on the surface of the fixing ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets a fixing ring on the surface of the pier body, and the position of the push plate can be adjusted by sliding the slide inside the annular groove. The support body placed on the top of the pad stone can be pushed by controlling the extension of the extension end of the electric telescopic rod. This allows for easy and precise adjustment of the position of the support body, thereby improving the installation accuracy of the railway bridge pier support body.

[0019] 2. In this application, after the fixing ring is fitted onto the top of the pier body, an external hex wrench is inserted into the internal hex head and rotated to lock the rotating column. At this time, the limiting cone will be in close contact with the surface of the pier body, making the connection between the fixing ring and the pier body more stable and preventing the fixing ring from rotating on the surface of the pier body.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A railway bridge pier support installation device includes a pier body 1, a pad stone 2 and a support body 3. A fixing ring 4 is fitted on the surface of the pier body 1. A push fine adjustment mechanism 5 is provided on the top of the fixing ring 4. Limiting mechanisms 7 are provided on both sides of the bottom of the fixing ring 4.

[0030] The fine-tuning mechanism 5 includes an anti-slip pad 501, a push plate 502, an electric telescopic rod 503, and a slide 504. The left side of the anti-slip pad 501 is fixedly connected to the right side of the push plate 502, the right side of the telescopic end of the electric telescopic rod 503 is fixedly connected to the left side of the push plate 502, and the left side of the electric telescopic rod 503 is fixedly connected to the right side of the slide 504.

[0031] In this embodiment: using external lifting equipment, the support body 3 is lifted to the top of the pier body 1 and fitted onto the surface of the pier body 1 via the hook 8 on the fixing ring 4. The limiting ring 10 ensures its stable position and prevents excessive downward movement. Then, the internal hexagonal screw head 704 is rotated, driving the rotating column 703 to bring the clamping plate 701 closer to the pier, so that the surface of the limiting cone 12 is in contact with the surface of the pier body 1, thus securing the fixing ring 4 to prevent rotation. After the support body 3 is placed on the pad stone 2 to initially determine its position, when fine adjustment is needed, the extension end of the electric telescopic rod 503 is controlled to push the push plate 502, and the anti-slip pad 501 contacts and pushes the support body 3. By controlling the extension amount of the extension end of the electric telescopic rod 503, precise fine adjustment in the horizontal direction can be achieved. Furthermore, the pull ring 11 can be used to pull the slide 504, which in turn moves the push plate 502 and the anti-slip pad 501, allowing for fine-tuning from different positions. This avoids the problem that some existing systems do not adequately consider fine-tuning functions when installing railway bridge pier supports. Some simple hoisting equipment simply places the support roughly in a predetermined position on the railway bridge pier without being equipped with a fine adjustment device. In such cases, once the support is in place, it becomes very difficult to change its position. When the support is heavy, it is difficult for construction workers to accurately adjust its position after placement using manual handling and simple tools, which affects the installation accuracy of the railway bridge pier support.

[0032] Specifically, such as Figure 4As shown, the limiting mechanism 7 includes a clamping plate 701, a bearing 702, a rotating column 703, and an internal hexagonal screw head 704. The outer wall of the bearing 702 is fixedly connected to the clamping plate 701 on the side close to the clamping plate 701. The surface of the rotating column 703 is fixedly connected to the inner wall of the bearing 702. The internal hexagonal screw head 704 is fixedly connected to the rotating column 703 on the side close to the rotating column 703.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, fixing plates 6 are fixedly connected to both sides of the bottom of the fixing ring 4, and the rotating column 703 is threaded into the inside of the fixing plate 6.

[0034] Specifically, such as Figure 1 and Figure 5 As shown, each of the two clamping plates 701 is fixedly connected to a limiting cone 12 on one side opposite to the other. The limiting cone 12 is a number of cones and is evenly distributed on the surface of the clamping plate 701. The surface of the limiting cone 12 is in close contact with the surface of the pier body 1.

[0035] In this embodiment: after the fixing ring 4 is fitted onto the surface of the pier body 1, an external hex wrench is inserted into the internal hex head 704 and rotated, which causes the rotating column 703 to rotate. The rotating column 703 is connected to the inside of the fixing plate 6 by a thread. When the rotating column 703 rotates, the clamping plate 701 moves closer to the surface of the pier body 1, so that the limiting cone 12 makes precise contact with the surface of the pier body 1, increasing the friction and thus limiting the fixing ring 4 to prevent the fixing ring 4 from rotating. The rotating column 703 is rotatably connected to the clamping plate 701 through the bearing 702, which prevents the clamping plate 701 from rotating with the rotating column 703.

[0036] Specifically, such as Figure 2 As shown, the fixed ring 4 has an annular groove 9 inside, and the slide 504 is slidably connected inside the annular groove 9.

[0037] Specifically, such as Figure 3 As shown, pull rings 11 are fixedly connected to both the front and rear sides of the carriage 504.

[0038] In this embodiment: by sliding the slide 504 inside the annular groove 9, the position of the slide 504, the electric telescopic rod 503, the push plate 502 and the anti-slip pad 501 can be easily moved, and the support body 3 can be pushed and fine-tuned from different directions. By pulling the hand pull ring 11, the slide 504 can be easily slid inside the annular groove 9.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the top of the fixing ring 4 is fixedly connected to the limiting ring 10, and the bottom of the fixing ring 4 is in contact with the top of the pier body 1.

[0040] Specifically, such as Figure 2 As shown, four hooks 8 are fixedly connected to the surface of the fixing ring 4 and are evenly distributed on the surface of the fixing ring 4.

[0041] In this embodiment: after the fixing ring 4 is fitted onto the surface of the pier body 1, the bottom of the limiting ring 10 will contact the top of the pier body 1, ensuring that the fixing ring 4 is stable at the top of the pier body 1 and preventing the fixing ring 4 from continuing to move down. By using an external lifting device to connect with the lifting buckle 8, the fixing ring 4 can be easily lifted to the top of the pier body 1.

[0042] Working principle: Using four evenly distributed lifting buckles 8 on the surface of the fixing ring 4, an external lifting device is connected to the lifting buckles 8 to hoist the fixing ring 4 to the top of the pier body 1. The fixing ring 4 is then fitted onto the surface of the pier body 1, and the bottom of the limiting ring 10 contacts the top of the pier body 1 to ensure the stability of the fixing ring 4 at the top of the pier body 1, preventing it from moving further down. Then, an external hex wrench is inserted into the internal hex head 704 and rotated, which drives the rotating column 703 to rotate within the internal thread of the fixing plate 6. Due to the bearing 702, the clamping plate 701 will not rotate with the rotating column 703. As the rotating column 703 rotates, the clamping plate 701 moves closer to the pier body 1. The evenly distributed limiting cones 12 on its surface make precise contact with the surface of the pier body 1, increasing friction and stabilizing the fixing ring 4 to prevent it from rotating during subsequent operations. After placing the support body 3 on the pad stone 2 and initially determining its position, when fine-tuning of the support body 3 is needed, the extension end of the electric telescopic rod 503 is activated, which pushes the push plate 502 to move, making the surface of the anti-slip pad 501 contact the surface of the support body 3 and push the support body 3. The precise extension and retraction of the electric telescopic rod 503 can control the push plate. The displacement of the support 502 allows for easy and precise fine-tuning of the support body 3 in the horizontal direction. This is achieved by pulling the hand-held pull ring 11. Since the slide 504 slides inside the annular groove 9, the slide 504, push plate 502, and anti-slip pad 501 can be easily pulled, thus moving their positions. This facilitates fine-tuning of the support body 3 from different positions. When the anti-slip pad 501 contacts the support body 3, pushing it, the surface of the slide 504 makes close contact with the inner wall of the annular groove 9, increasing friction. This friction then acts as a force to adjust the slide... By limiting the movement of the 504 slide, the problem of insufficient fine-tuning function in the installation of railway bridge pier supports can be avoided. Some simple hoisting equipment simply places the support roughly in a predetermined position on the railway bridge pier without being equipped with a fine adjustment device. In this case, it becomes very difficult to change the position of the support once it is in place. When the support is heavy, it is difficult for construction workers to make precise adjustments to its position after placement using manual handling and simple tools, which affects the installation accuracy of railway bridge pier supports.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
