Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically a quick-assembly support for steel box girders in bridge engineering. Background Technology

[0002] Bridge engineering refers to the process of constructing, designing, maintaining and repairing bridges. Steel box girders are a commonly used structure in bridge engineering. When constructing steel box girders, a support frame is needed to provide initial support for the steel box girders.

[0003] Current scaffolding systems cannot be installed quickly and require the use of specific tools and a large number of bolts to connect the scaffolding systems, making installation troublesome, time-consuming, labor-intensive, and inconvenient. To address this, we propose a quick scaffolding system for assembling steel box girders in bridge engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-assembly support for steel box girders in bridge engineering, so as to solve the problem that the current supports cannot be installed quickly, and require the use of specific tools and a large number of bolts to connect the supports, which makes the installation troublesome, time-consuming and labor-intensive, and not convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly support for steel box girders in bridge engineering, comprising a base plate, a support column fixedly connected to the top center of the base plate, a rotating shaft fixedly connected to the top of the support column, a first connecting mechanism provided on the outer side of the rotating shaft, a support plate connected to the top of the support column through the first connecting mechanism, a second connecting mechanism evenly provided on the outer side wall of the support column, and a crossbar connected between two support columns through the second connecting mechanism.

[0006] Preferably, the first connecting mechanism includes a rotating block rotatably connected to the outer wall of the rotating shaft. The top of the rotating block is symmetrically provided with mounting cavities. A return spring is fixedly connected to one side of the mounting cavity. A connecting plate is fixedly connected to the end of the return spring. A locking block is fixedly connected to the top of one side of the connecting plate. A pressing rod is fixedly connected to the bottom of one side of the connecting plate. A connecting block is symmetrically fixedly connected to the bottom of the support plate. A locking groove is provided on the bottom edge of the connecting block. A moving groove is symmetrically provided on the bottom of the connecting block.

[0007] Preferably, a screw is connected through the middle of the outer side wall of the rotating block, and screw holes are evenly provided on the outer side wall of the rotating shaft. The rotating block is fixed by the cooperation of the screw and the screw holes to prevent the rotating block from rotating after connection.

[0008] Preferably, a retaining ring is fixedly connected to the top of the outer side wall of the rotating shaft, and an annular groove is formed on the top of the rotating block, with the retaining ring located inside the annular groove, to limit the rotation block and prevent it from detaching from the rotating shaft.

[0009] Preferably, the connecting plate is slidably connected to the interior of the mounting cavity, and the pressing rod passes through the outer side wall of the rotating block, so that the connecting plate moves stably.

[0010] Preferably, the second connecting mechanism includes a sleeve uniformly and fixedly connected to the outer wall of the support column. A compression spring is fixedly connected to the middle of one side of the inner cavity of the sleeve. One end of the compression spring is fixedly connected to a stop plate. The outer wall of the sleeve is symmetrically provided with L-shaped grooves. A limit groove is provided on one side of the L-shaped groove. Limit blocks are symmetrically fixedly connected to both ends of the outer wall of the crossbar.

[0011] Preferably, the abutment is slidably connected to the inside of the sleeve, and the outer side wall of the abutment is in contact with the inner side wall of the sleeve. The diameter of the crossbar is equal to the inner diameter of the sleeve, so that the crossbar is in contact with the inside of the sleeve and avoids shaking.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, by using the first connecting mechanism, pressing the actuating rod causes the connecting plate to move the locking blocks, bringing the locking blocks closer together and squeezing the return spring. This places the locking blocks inside the moving groove. Releasing the actuating rod causes the return spring to reset the connecting plate, allowing the locking blocks to engage in the slot. This facilitates the connection between the support plate and the support column, avoiding the need to use tools to connect a large number of bolts, saving time, reducing labor, making assembly faster, and improving the convenience of the device.

[0014] 2. In this application, by utilizing the second connecting mechanism, the crossbar is placed inside the sleeve, and the limiting block is located in the L-shaped groove. This compresses the two support columns, bringing them closer together. Consequently, the crossbar presses against the abutment, causing the compression spring to deform. Simultaneously, the limiting block is positioned at the bottom of the L-shaped groove. Rotating the crossbar aligns the limiting block with the limiting groove, loosening the support columns. The abutment is then reset by the resetting of the compression spring, allowing the limiting block to remain in the limiting groove for crossbar installation. This simplifies and facilitates installation, saves time, avoids the use of bolts for connection, and makes it easier to connect the support columns, thus improving convenience.

Detailed Implementation

[0022] 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.

[0023] Example: Figures 1-6 As shown, this utility model provides a technical solution for a quick-assembly support for steel box girders in bridge engineering, including a base plate 100, a support column 200 fixedly connected to the top center of the base plate 100, a rotating shaft 490 fixedly connected to the top of the support column 200, a first connecting mechanism 400 provided on the outer side of the rotating shaft 490, a support plate 300 connected to the top of the support column 200 through the first connecting mechanism 400, a second connecting mechanism 600 evenly provided on the outer side wall of the support column 200, and a crossbar 700 connected between two support columns 200 through the second connecting mechanism 600.

[0024] Please see Figure 2 , Figure 3 and Figure 4The first connecting mechanism 400 includes a rotating block 410 rotatably connected to the outer wall of the rotating shaft 490. The top of the rotating block 410 has symmetrically arranged mounting cavities 420. A return spring 430 is fixedly connected to one side of the mounting cavity 420. A connecting plate 440 is fixedly connected to the end of the return spring 430. A locking block 450 is fixedly connected to the top of one side of the connecting plate 440. A pressing rod 460 is fixedly connected to the bottom of one side of the connecting plate 440. A connecting block 470 is symmetrically fixedly connected to the bottom of the support plate 300. A locking groove 480 is formed on the bottom edge of the connecting block 470, and a moving groove 481 is symmetrically formed on the bottom of the connecting block 470. A screw 500 is threaded through the middle of the outer wall of the rotating block 410. Screw holes 510 are evenly arranged on the outer wall of the rotating shaft 490. A retaining ring is fixedly connected to the top of the outer wall of the rotating shaft 490. The top of block 410 has an annular groove, and the retaining ring is located inside the annular groove; the connecting plate 440 is slidably connected to the inside of the mounting cavity 420, and the push rod 460 passes through the outer wall of the rotating block 410; by using the first connecting mechanism 400, pressing the push rod 460 causes the connecting plate 440 to move the retaining block 450, so that the retaining blocks 450 move closer to each other, squeezing the return spring 430 and placing the retaining block 450 inside the moving groove 481. Loosening the push rod 460, through the return spring 430, causes the connecting plate 440 to move the retaining block 450 back to its original position, so that the retaining block 450 is engaged in the retaining groove 480, thereby facilitating the connection of the support plate 300 and the support column 200, avoiding the need to use tools to connect a large number of bolts, saving time, reducing labor, making assembly faster, and improving the convenience of the device.

[0025] Please see Figure 5 and Figure 6The second connecting mechanism 600 includes a sleeve 610 uniformly fixedly connected to the outer wall of the support column 200. A compression spring 620 is fixedly connected to the middle of one side of the inner cavity of the sleeve 610. A stop plate 630 is fixedly connected to one end of the compression spring 620. L-shaped grooves 640 are symmetrically opened on the outer wall of the sleeve 610. A limit groove 650 is opened on one side of the L-shaped groove 640. Limit blocks 660 are symmetrically fixedly connected to both ends of the outer wall of the crossbar 700. The stop plate 630 is slidably connected to the inside of the sleeve 610, and the outer wall of the stop plate 630 is in contact with the inner wall of the sleeve 610. The diameter of the crossbar 700 is equal to the inner diameter of the sleeve 610. By using the second connecting mechanism 600, the crossbar 700 can be positioned... Inside the sleeve 610, the limiting block 660 is positioned in the L-shaped groove 640, pressing the two support columns 200 together. This causes the crossbar 700 to press against the abutment plate 630, deforming the compression spring 620. Simultaneously, the limiting block 660 is positioned at the bottom of the L-shaped groove 640. Rotating the crossbar 700 aligns the limiting block 660 with the limiting groove 650, loosening the support columns 200. The abutment plate 630 is then reset by the reset of the compression spring 620, placing the limiting block 660 in the limiting groove 650 for installation of the crossbar 700. This simple and convenient installation saves time, avoids the use of bolts for connection, and facilitates the connection between the support columns 200, improving ease of use.

[0026] In use, this utility model is assembled as follows: The crossbar 700 is placed inside the sleeve 610, with the limiting block 660 positioned in the L-shaped groove 640. The two support columns 200 are pressed together, bringing them closer. This causes the crossbar 700 to press against the abutment plate 630, deforming the compression spring 620. Simultaneously, the limiting block 660 is positioned at the bottom of the L-shaped groove 640. The crossbar 700 is rotated until the limiting block 660 aligns with the limiting groove 650. The support columns 200 are loosened, and the abutment plate 630 is reset by the reset of the compression spring 620. The limiting block 660 is then positioned in the limiting groove 650, allowing the crossbar 700 to be installed. Afterward, the actuating rod 460 is pressed, causing the connecting plate 440 to move the locking block. Move 450 to bring the locking blocks 450 closer together, pressing the return spring 430 and placing the locking blocks 450 inside the moving groove 481. Loosen the push rod 460, and through the reset of the return spring 430, the connecting plate 440 drives the locking blocks 450 to reset, so that the locking blocks 450 are locked in the slot 480. Rotate the rotating block 410 to deflect it, so that the connecting plate 440 is in contact with the side wall of the slot 480, limiting the connection plate 440 and preventing it from moving, thus ensuring the stability of the connection. Then align the screw 500 with the screw hole 510 and screw the screw 500 into the screw hole 510 to fix the rotating block 410, and connect the support plate 300 and the support column 200.
