Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a safety guidance device for bridge construction. Background Technology

[0002] Bridge construction refers to the process of building a bridge according to its design specifications. It mainly includes bridge construction technology, construction organization, construction management, and construction quality. During bridge construction, it is necessary to position and install the lower steel reinforcement cage, and a guiding device is used to guide the lower steel reinforcement cage to facilitate installation.

[0003] A search of the Chinese patent "A Highly Safe Bridge Construction Reinforcing Cage Guiding Device" (publication number CN214460403U) reveals that this patent utilizes a combination of a bidirectional screw, a guiding arc rod, a first pulley, a second pulley, and a crank handle to guide the reinforcing cage smoothly and vertically into the pile hole. This reduces the workload of operators and avoids the risk of workers falling into the pile hole. The clamping method used to guide the reinforcing cage also prevents it from falling during lifting, thus protecting the safety of surrounding workers and meeting other safety requirements. The different specifications of the rebar cages required for lowering expand the application scenarios and scope of this device. When installing the lower rebar cage, the device uses a bidirectional screw that works in conjunction with the mounting base to move the guide arc rod inward to clamp the lower rebar cage and position it for installation. However, when positioning the lower rebar cage, it is not convenient for the lower rebar cage to move downward and insert into the pile hole after being clamped by the two guide arc rods. When the guide arc rods are released, the lower rebar cage is prone to shifting, making it inconvenient to guide and position the lower rebar cage and reducing the effectiveness of the device.

[0004] Therefore, a safety guidance device for bridge construction is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a safety guidance device for bridge construction in order to solve the above-mentioned problems and improve the problem of inconvenience in guiding and positioning the lower steel cage.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a safety guidance device for bridge construction, comprising two base plates, with a guide plate fixedly connected to the top of each base plate; a guidance mechanism, which facilitates the positioning and guidance of the lower reinforcing cage, is disposed on the inner wall of the base plates; wherein, the guidance mechanism includes several first rotating rods evenly distributed and rotatably connected to the inner wall of the guide plate; a limit plate is slidably connected to the inner wall of the base plate; several second rotating rods are rotatably connected to the inner wall of the limit plate; an assembly assembly is provided on the inner wall of the base plate; the guide plate is conical in shape, decreasing in size, and cooperates with the first rotating rods to guide the lower reinforcing cage; when the two limit plates clamp and position the lower reinforcing cage, the second rotating rods can guide and transport the lower reinforcing cage.

[0007] Preferably, the guiding mechanism further includes sliders fixedly connected to both sides of the base plate, the sliders being slidably connected to the inner wall of the base plate, and a lead screw being rotatably connected to the inner wall of the base plate. The lead screw is threadedly connected to one of the sliders, and the limiting plate can move towards the center to clamp and position the lower steel cage by cooperating with the sliders on both sides and the lead screw.

[0008] Preferably, one end of one of the lead screws is fixedly connected to a connecting block, and one end of the connecting block extends through the inner wall of the other lead screw, driving one lead screw to insert into the other lead screw through the cross-shaped connecting block and causing it to rotate, so that the two limiting plates can move simultaneously to position the lower steel cage.

[0009] Preferably, a guide rod is fixedly connected to the other side of the inner wall of the base plate, and another slider is slidably connected to the guide rod, which can guide and support the limiting plate.

[0010] Preferably, the assembly includes two locking blocks hinged to one end of one of the base plates, and two locking slots that engage with the locking blocks at one end of the other base plate. The locking blocks and locking slots cooperate to install the two base plates together to guide and position the lower reinforcing cage.

[0011] Preferably, a handle is fixedly connected to the top of the card block, which allows for quick installation and removal of the card block.

[0012] Preferably, a positioning rod is provided on the top of both sides of the base plate, one end of which penetrates through the base plate. The positioning rod can cooperate with the pile hole to position and install the two base plates.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting a guiding mechanism, the diameter of the guide plates on the two base plates gradually decreases from top to bottom. In conjunction with the first rotating rod, the lower rebar cage can be guided. The two limiting plates can move simultaneously from one end to the other through the cooperation of the slider and the lead screw to clamp the lower rebar cage. When the limiting plates clamp the lower rebar cage, the lower rebar cage can be guided and transported through the second rotating rod. One of the lead screws can drive the other lead screw to rotate through the cross-shaped connecting block at one end, driving the two limiting plates. The guide rod and the other slider can support and guide the limiting plates, which can effectively guide and position the lower rebar cage, making it convenient for the installation of the lower rebar cage.

[0015] 2. By setting up assembly components, one of the base plates is fitted into the slot by two clips, which can install the two base plates together and guide and position the lower rebar cage. Both the clips and the slot are T-shaped to ensure stable installation of the base plate. The positioning rod can position the installation position of the two base plates, which can accurately install the lower rebar cage and improve the installation effect of the lower rebar cage.

[0021] 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.

[0022] In practical implementation: such as Figure 1-4As shown, a safety guidance device for bridge construction includes two base plates 1, with a guide plate 2 fixedly connected to the top of the base plates 1; a guidance mechanism 3, which facilitates the positioning and guidance of the lower rebar cage, is disposed on the inner wall of the base plates 1; wherein, the guidance mechanism 3 includes several evenly distributed and rotatably connected first rotating rods 301 to the inner wall of the guide plate 2, a limit plate 302 is slidably connected to the inner wall of the base plates 1, and several evenly distributed second rotating rods 303 are rotatably connected to the inner wall of the limit plate 302, and an assembly assembly 308 is provided on the inner wall of the base plates 1. The guide plate 2, through its conical shape, can guide the lower rebar cage after it has been lifted, and guides it downward through the first rotating rods 301. When it moves to a certain position, the lower rebar cage is clamped by the two limit plates 302. The second rotating rods 303 on the inner wall of the limit plate 302 can guide and transport the lower rebar cage while it is clamped, thereby guiding and positioning the lower rebar cage and improving its installation effect.

[0023] like Figure 2 and Figure 3 As shown, the guiding mechanism 3 also includes sliders 304 fixedly connected to both sides of the base plate 1. The sliders 304 are slidably connected to the inner wall of the base plate 1. A lead screw 305 is rotatably connected to the inner wall of the base plate 1. The lead screw 305 is threadedly connected to one of the sliders 304. A connecting block 306 is fixedly connected to one end of the lead screw 305, and one end of the connecting block 306 extends through the inner wall of the other lead screw 305. A guide rod 307 is fixedly connected to the other side of the inner wall of the base plate 1. The other slider 304 is slidably connected to the guide rod 307. When the two base plates 1 are installed together... One lead screw 305 is inserted into the other lead screw 305 through a connecting block 306, so that the two lead screws 305 rotate simultaneously and are threadedly connected to two sliders 304, which drives the limiting plate 302 to move from one end to the middle to clamp and position the lower rebar cage. When clamping the lower rebar cage, the limiting plate 302 can be guided by the second rotating rod 303. The two guide rods 307 cooperate with the other two sliders 304 to support and guide the limiting plate 302, which facilitates the clamping and positioning of the lower rebar cage and improves the installation accuracy of the lower rebar cage.

[0024] like Figure 4As shown, the assembly component 308 includes two locking blocks 3081 hinged to one end of one of the base plates 1, and two locking slots 3082 that engage with the locking blocks 3081 at one end of the other base plate 1. A handle 3083 is fixedly connected to the top of the locking blocks 3081. Positioning rods 3084 are provided on the top of both sides of the base plate 1, with one end of the positioning rod 3084 penetrating through the base plate 1. The two locking blocks 3081 and the locking slots 3082 can be used to install and connect the two base plates 1. The installation position of the base plate 1 can be positioned by the positioning rods 3084. The two locking blocks 3081 can be driven out of the locking slots 3082 by the handles 3083 to disassemble them. The device can be recycled, which is convenient for guiding the installation of the lower steel cage.

[0025] In use, the locking block 3081 is manually rotated to embed it into the locking groove 3082, and the two base plates 1 are installed. Then, the positioning rod 3084 is inserted through the base plate 1 into the pile hole for positioning. The lower steel cage is lifted and transported by a crane, and comes into contact with the guide plate 2. It moves downward through the first rotating rod 301. One of the lead screws 305 is manually rotated, which drives the other lead screw 305 to rotate through the connecting block 306. The two lead screws 305 are threadedly connected to two sliders 304, which drives the limiting plate 302 to move towards the middle to clamp the lower steel cage. Then, it cooperates with the second rotating rod 303 to guide and transport the lower steel cage.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
