Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and more specifically, to a device for installing a cover plate along the beam of a high-speed railway bridge. Background Technology

[0002] High-speed railway bridges are bridges specifically designed for high-speed railway trains traveling at speeds of 250 km / h and above. They are the most critical and predominant structures on high-speed railway lines. Protective shields are protective components installed on both sides of high-speed railway bridges. They are standard auxiliary structures of high-speed railway bridges and are mainly used for protection, sound insulation, and beautifying the bridge's facade.

[0003] Traditional installation equipment is often directly tied to the shield with steel wire ropes, which is not secure and is prone to slippage. During installation, the shield is prone to shaking and shifting, making it difficult to achieve precise installation, resulting in low construction efficiency and affecting installation quality. On the other hand, manual handling and installation are also problematic because the shield is mostly a precast concrete component with a large self-weight, making it easy to be bumped and damaged during manual handling, and there are also safety hazards such as falls from heights and sprains. Utility Model Content

[0004] This utility model aims to solve the problems of existing installation equipment and cover plates being connected by directly binding with steel wire ropes, which is not secure, easy to slip, and the cover plate is prone to shaking and shifting during installation, making it difficult to achieve precise installation, resulting in low construction efficiency and affecting installation quality.

[0005] To address the aforementioned problems, this utility model provides a high-speed railway bridge cover plate installation device, comprising a traveling transport and hoisting device, a support structure, and a suspension structure connected to the support structure. The supporting structure is connected to the traveling transport and hoisting device and is used to support the suspended structure; The suspension structure and the cover plate are detachable and installable. When the traveling transport and hoisting device is working, it is used to hoist the cover plate onto the high-speed railway bridge. The traveling transport and hoisting device is a forklift, and the support structure includes a support beam. The bottom of the support beam is equipped with a bearing frame connected to the suspension structure and two mounting sleeves. The mounting sleeves are fitted onto the forks of the corresponding forklift. The suspension structure includes a hook and a suspension component that is detachably installed with the cover plate. One end of the hook is movably connected to the support frame, and the other end is detachably connected to the suspension component.

[0006] The present invention provides a high-speed railway bridge shield installation device that, compared with the prior art, has the following beneficial effects, but is not limited to: This high-speed railway bridge canopy installation device, which involves mounting a support structure on a traveling transport and hoisting device, utilizes a support beam as a base. Two mounting sleeves and a load-bearing frame are fixedly installed on this support beam. A forklift is then used as the traveling transport and hoisting device, which is more convenient and flexible than using large lifting equipment (such as truck cranes or gantry cranes). The mounting sleeves are then mounted on the forklift's forks. A suspension structure is then used to connect the installation to the support structure. In the installation work area, the suspension structure is fixed to the top of the canopy using a hook and suspension components, with one end of the hook movably connected to the load-bearing frame. The other end of the hook is detachably connected to the suspension component. This detachable connection allows for pre-installation of the suspension component on each panel. Multiple panels with installed suspension components are then transported to the installation area. During panel hoisting, workers directly hook the hook (movably connected to the support frame) onto the suspension component, enabling rapid hoisting and avoiding the time-consuming process of installing suspension components on each panel individually in the installation area. The hoisting device operates via a traveling transport system, with the stable support structure lifting the panel vertically. The installation process begins with the cover plate being hoisted onto the high-speed railway bridge. Workers on the bridge assist in the installation, ultimately placing the cover plate into its designated installation area. The workers then utilize the detachable connection between the suspension structure and the cover plate to separate them, allowing for the installation of the next cover plate. Specifically, after the cover plate is installed in the installation area, the detachable connection between the hook and the suspension component facilitates separation, enabling the installation of the next cover plate. This detachable connection also facilitates the removal of the suspension components from the cover plate installed in the installation area. The panels can be removed and reused on the next batch of panels to be installed, achieving reuse and saving costs. In summary, by using a suspended structure for installation and fixing of the panels, and making them detachable, the problems of direct binding with steel wire ropes, such as insecure fixing, easy slippage, easy shaking and displacement of the panels during installation, difficulty in achieving precise installation, and low construction efficiency are solved. Moreover, only manual assistance is required, avoiding direct manual handling and installation, thus avoiding damage caused by the handling of the panels, avoiding safety hazards such as falls from heights and sprains. The structure is simple, the operating cost is low, and it can be installed simultaneously with the beams, without waiting for the high-speed railway bridge to be fully completed.

[0007] Furthermore, the support frame is located between two mounting sleeves, which are fixed to the forklift's fork arm by fasteners.

[0008] Furthermore, the suspension component includes a U-shaped lifting ring and a connecting plate, the connecting plate being fixedly connected to the U-shaped lifting ring, and the connecting plate having mounting holes that cooperate with the pre-embedded screws on the cover plate.

[0009] Furthermore, the fasteners include fastening bolts and fastening nuts, and both the mounting sleeve and the fork arm of the forklift are provided with positioning through holes for the fastening bolts to be inserted.

[0010] Furthermore, the support frame includes an arc segment and two straight segments welded to the support beam. The arc segment is located between the two straight segments. The arc segment and the two straight segments are an integral structure and are made of bent round steel.

[0011] Furthermore, the hook includes a connecting body, one end of which is provided with a hook handle that is movably sleeved on the support frame, and the other end of which is provided with a hook body, and a safety tongue is provided at the hook opening of the hook body.

[0012] Furthermore, the support beam is made of I-beams.

[0013] Furthermore, the two mounting sleeves are made of square steel tubing and are welded to the support beam.

[0014] Furthermore, there are four mounting holes, which are respectively located at the top four corners of the connecting plate. Attached Figure Description

[0024] See Figures 1-3 , Figure 7 and Figure 8 This utility model provides a high-speed railway bridge cover plate installation device, which includes a traveling transport and hoisting device, a support structure 2, and a suspension structure 3 connected to the support structure 2. The support structure 2 is connected to the traveling transport and hoisting device and is used to support the suspended structure 3; The suspension structure 3 and the cover plate 4 can be detached and installed. When the traveling transport and hoisting device is working, it is used to hoist the cover plate 4 onto the high-speed railway bridge. The traveling transport and hoisting device is a forklift 1. The support structure 2 includes a support beam 201. The bottom of the support beam 201 is equipped with a bearing frame 203 connected to the suspension structure 3 and two mounting sleeves 202. The mounting sleeves 202 are fitted onto the fork arms 101 of the corresponding forklift 1. The suspension structure 3 includes a hook 301 and a suspension member 302 that can be detachably installed with the cover plate 4. One end of the hook 301 is movably connected to the support frame 203, and the other end is detachably connected to the suspension member 302.

[0025] In this embodiment, the high-speed railway bridge cover plate installation device is installed on a traveling transport and hoisting device by installing a support structure 2. That is, based on the support beam 201, two mounting sleeves 202 and a bearing frame 203 are fixedly installed on it. Then, a forklift 1 is used as the traveling transport and hoisting device, which is more convenient and flexible than hoisting with large lifting equipment (such as truck cranes and gantry cranes). The mounting sleeves 202 are then fitted onto the fork arms 101 of the forklift 1. Next, a suspension structure 3 is used to install and connect with the support structure 2. In the installation work area, the suspension structure 3 is installed and fixed to the top of the cover plate 4, that is, by using a hook 301 and a suspension component 302 to fix the hook 301 to the top of the cover plate 4. One end of the hook 301 is movably connected to the support frame 203, and the other end of the hook 301 is detachably connected to the suspension component 302. This detachable connection between the suspension component 302 and the hook 301 facilitates the pre-fixing and installation of the suspension component 302 on each cover plate 4. Then, multiple cover plates 4 with the suspension component 302 installed are transported to the installation work area. When hoisting and installing the cover plates 4, the workers directly hook the hook 301, which is movably connected to the support frame 203, onto the suspension component 302, thus enabling rapid hoisting and avoiding the increased work time required to install the suspension component 302 for each cover plate 4 in the installation work area. The hoisting is carried out using a traveling transport hoisting device, supported by the stable structure 2. Under the action of the suspension structure 3, the cover plate 4 is lifted and placed in a vertical installation position. Finally, the cover plate is hoisted onto the high-speed railway bridge. Workers on the high-speed railway bridge assist in the operation, ultimately installing the cover plate 4 into the installation area on the bridge. Workers then use the detachable connection between the suspension structure 3 and the cover plate 4 to separate them, and then proceed with the installation of the next cover plate 4. That is, after the cover plate 4 is installed in the installation area, the hook 301 and the suspension component 302 are detachably connected, facilitating the disassembly of the hook 301 and the suspension component 302, thus enabling the hoisting and installation of the next cover plate 4. The detachable connection between the suspension component 302 and the cover plate 4 facilitates... The suspension component 302 installed on the cover plate 4 in the installation area is disassembled and then used on the next batch of cover plates 4 to be installed, achieving reuse and saving costs. In summary, by using the suspension structure 3 to install and fix the cover plate 4 and making it detachable, the problems of direct binding with steel wire ropes, which are not firmly fixed, easy to slip, easy to shake and shift during the installation process, making it difficult to achieve precise installation and resulting in low construction efficiency are solved. Moreover, only manual assistance is required, avoiding direct manual handling and installation, thereby avoiding collision damage caused by the handling of the cover plate, avoiding safety hazards such as falling from height and sprains. In addition, the structure is simple, the use cost is low, and it can be installed simultaneously with the beam without waiting for the high-speed railway bridge to be fully completed.

[0026] It should be noted that for the cover plate 4 that needs to be installed on the high-speed railway bridge, multiple cover plates 4 are first transported to the installation work area by an electric flatbed truck 5 (existing technology, capable of automatic movement and carrying cargo). Then, the traveling transport hoisting device hoists and installs them one by one to the installation area of ​​the cover plate 4 through the support structure 2 and the suspension structure 3.

[0027] See Figure 2 and Figure 3 Optionally, the support frame 203 is located between two mounting sleeves 202, and the mounting sleeves 202 are fixed to the fork arm 101 of the forklift 1 by fasteners.

[0028] In this embodiment, by installing the support frame 203 between the two mounting sleeves 202, the suspension structure 3 connected to the support frame 203 is made stable during hoisting, and the cover plate 4 lifted by the suspension structure 3 is made stable in the vertical direction to avoid deviation and swaying. The mounting sleeve 202 is fitted onto the fork arm 101 of the forklift 1, and then the mounting sleeve 202 and the fork arm 101 of the forklift 1 are fixed by fasteners, so that the support structure 2 can be fixedly installed on the fork arm 101 of the forklift 1 and can be raised and lowered smoothly together with the fork arm 101 of the forklift 1.

[0029] Specifically, forklift 1 is a four-way forklift with the following features: the wheels can turn 90°, and it can move forward, backward, left and right without turning first, which facilitates small-scale forward, backward and left and right movement on site. On the work site, the four-way forklift is used to move forward, backward and left and right within a small range and its fork arm 101 is used to lift and lower to complete the installation of the cover plate 4.

[0030] See Figure 3 and Figure 5 Optionally, the suspension component 302 includes a U-shaped lifting ring 3021 and a connecting plate 3022. The connecting plate 3022 is fixedly connected to the U-shaped lifting ring 3021, and the connecting plate 3022 has a mounting hole 3023 that cooperates with the pre-embedded screw on the cover plate 4.

[0031] In this embodiment, the pre-embedded screw on the cover plate 4 is passed through the mounting hole 3023 on the connecting plate 3022, and then a nut is screwed onto the end of the pre-embedded screw that passes through the mounting hole 3023 to install and fix the connecting plate 3022 and the cover plate 4. The cover plate 4 is then lifted by hooking the hook 301 onto the U-shaped lifting ring 3021, so that it is in a vertical installation state. After the cover plate 4 is installed, the disassembly is completed by removing the hook 301 from the U-shaped lifting ring 3021. Then the nut is loosened from the pre-embedded screw, and the connecting plate 3022 is removed from the pre-embedded screw on the cover plate 4, so that the suspension component 302 composed of the U-shaped lifting ring 3021 and the connecting plate 3022 can be reused.

[0032] See Figure 4 Optionally, the fasteners include fastening bolts 204 and fastening nuts 205, and both the mounting sleeve 202 and the fork arm 101 of the forklift 1 are provided with positioning through holes 6 for the fastening bolts 204 to be inserted.

[0033] In this embodiment, by opening positioning through holes 6 on both the mounting sleeve 202 and the fork arm 101 of the forklift 1, the positioning through holes 6 of the two are aligned when the mounting sleeve 202 is put on the fork arm 101 of the forklift 1. Then, the fastening bolt 204 is inserted into the aligned positioning through holes 6, and the fastening nut 205 is tightened on the fastening bolt 204. This facilitates the fixing between the mounting sleeve 202 and the fork arm 101 of the forklift 1, and makes it easier to fix the entire support structure 2 on the two fork arms 101 of the forklift 1.

[0034] See Figure 6 Optionally, the support frame 203 includes an arc segment 2031 and two straight segments 2032 welded to the support beam 201. The arc segment 2031 is located between the two straight segments 2032. The arc segment 2031 and the two straight segments 2032 are an integral structure and are made of round steel bent into shape.

[0035] In this embodiment, two straight sections 2032 are welded to the support beam 201, which facilitates the installation and fixing of the support frame 203 and the support beam 201. The straight sections 2032 are also beneficial for welding, reducing weld seams, reducing incomplete welds, and improving weld strength. The hook 301 is connected and supported by the arc section 2031, so that the hook 301 remains stable at the lowest position of the arc section 2031 during each hoisting. The support frame 203, which is made of the arc section 2031 and the two straight sections 2032 by directly bending round steel, makes the overall structure stable.

[0036] See Figure 6 Optionally, the hook 301 includes a connecting body 3012, one end of which is provided with a hook handle 3011, which is movably sleeved on the support frame 203, and the other end of the connecting body 3012 is provided with a hook body 3013, and a safety tongue 3014 is provided at the hook opening of the hook body 3013.

[0037] In this embodiment, the hook 3011 is movably sleeved on the support frame 203, so that the hook 301 remains movable, making it easy for the hook body 3013 to hook onto the U-shaped lifting ring 3021 of the suspension member 302 through the hook opening, and then the safety tongue 3014 at the hook opening of the hook body 3013 prevents the U-shaped lifting ring 3021 from falling off, thereby improving safety.

[0038] See Figure 1 Optionally, the support beam 201 is made of I-beams.

[0039] In this embodiment, the I-beam has excellent bending strength and structural rigidity, high load-bearing capacity, and can meet the stress and installation requirements during the hoisting and installation of the shield 4. It is also easy to obtain (it can be obtained directly from the construction site).

[0040] See Figure 2 Optionally, the two mounting sleeves 202 are made of square steel tubes and are welded to the support beam 201.

[0041] In this embodiment, the square steel tube has good structural strength and torsional resistance, which can directly meet the assembly requirements of the fork arm 101 of the forklift 1, and is easy to obtain (it can be obtained directly from the construction site). By welding the two mounting sleeves 202 to the support beam 201, the connection is firm, the integrity is strong, and the force is directly transmitted, which can ensure the stability and safety of the support structure 2 during the hoisting process.

[0042] See Figure 3 and Figure 5 Optionally, the number of mounting holes 3023 is four, and they are respectively opened at the top four corners of the connecting plate 3022.

[0043] In this embodiment, by opening mounting holes 3023 at the top four corners of the connecting plate 3022, and passing the pre-embedded screws on the cover plate 4 through the mounting holes 3023 on the connecting plate 3022 and fixing them with nuts, the four fixing points ensure that the cover plate 4 is subjected to uniform force and the connection is stable and reliable during hoisting. This effectively avoids deformation of the connecting plate 3022 and swaying and displacement of the cover plate 4 during hoisting, improves the hoisting positioning accuracy and operational safety, and is compatible with the arrangement position of the pre-embedded screws on the cover plate 4, making installation convenient and highly versatile.

[0044] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
