Description

Technical Field

[0001] The present application relates to the technical field of variable position steel frames, and in particular to a variable position steel frame that is convenient for erecting catwalk load-bearing cables. Background Art

[0002] When erecting the catwalk load-bearing cables of a suspension bridge, the load-bearing cables will stick together after passing over the saddles. A displacement device is needed to disperse the load-bearing cables to facilitate the erection of the catwalk. Usually, a displacement beam is set on the top of the tower, and a pull-down device is used to displace the load-bearing cables to meet the needs of laying the catwalk. However, the operation is cumbersome and it is difficult to work near the top of the tower. Therefore, some projects have adopted displacement steel frames for displacement, and used two sets of limit clamps to displace the load-bearing cables to a suitable position.

[0003] Regarding the above-mentioned related technologies, the existing variable position steel frame uses a limiting clamp to fix the load-bearing cable, which is difficult to install and difficult to adjust to cope with the load-bearing cables in different situations, and needs to be improved. Utility Model Content

[0004] The purpose of the present application is to provide a displacement steel frame that is convenient for erecting catwalk load-bearing cables, so as to improve the problem of difficulty in installing the displacement device of the catwalk load-bearing cables.

[0005] The present application provides a variable position steel frame for facilitating the installation of catwalk load-bearing cables, which adopts the following technical solution:

[0006] A variable steel frame for facilitating the erection of catwalk load-bearing cables comprises a steel frame and a load-bearing cable, the steel frame comprising a ring-shaped steel beam 1, a steel beam 2, a steel column 1, a steel column 3, and a steel column 2 connecting the steel beam 1 and the steel beam 2; a plurality of positioning blocks are respectively provided on both sides of the upper surface of the steel beam 1, a plurality of groups of limiting blocks are respectively provided on both sides of the upper surface of the steel beam 2, a plurality of fixing holes are provided on both sides of the steel beam 1 and the steel beam 2 corresponding to each load-bearing cable, and the fixing holes are grouped in pairs; a U-shaped lock is provided in each group of the fixing holes, and the load-bearing cable passes through the U-shaped lock and is offset against the positioning block and the limiting block.

[0007] By adopting the above technical solution, the load-bearing cable is abutted against one side of the positioning block and against one side of the limit block at the same time, and the limit block is used to shift the load-bearing cable to a dispersed state; at this time, the U-shaped lock is installed to prevent the load-bearing cable from detaching from the positioning block and the limit block, and the U-shaped lock can adapt to different types of load-bearing cables, and can also facilitate the movement of the displacement steel frame on the load-bearing cable; the positioning block, the limit block and the U-shaped lock are used in conjunction with the U-shaped lock to shift the load-bearing cable, and the installation is relatively simple and easy and can meet the displacement requirements.

[0008] Preferably, a first guide rounded corner is provided on the side of the positioning block that abuts against the load-bearing cable, and a second guide rounded corner is provided on the side of the limiting block that abuts against the load-bearing cable.

[0009] By adopting the above technical solution, guide fillet 1 and guide fillet 2 are respectively provided on the side where the positioning block and the limit block are in contact with the load-bearing cable, thereby reducing the friction between the positioning block, the limit block and the load-bearing cable, making installation easier; and avoiding excessive wear between the positioning block, the limit block and the load-bearing cable, thereby avoiding safety accidents.

[0010] Preferably, each group of positioning blocks on the first steel beam is provided with a fixed baffle; each group of limiting blocks on the second steel beam is provided with a fixed baffle.

[0011] By adopting the above technical solution, a fixed baffle is provided to prevent the displaced steel frame from directly separating from the load-bearing cable when the U-shaped lock fails, thereby preventing serious consequences.

[0012] Preferably, positioning grooves are provided at the positions where the first and second steel beams are fitted to fix the baffle.

[0013] By adopting the above technical solution, the positioning groove can easily locate the installation position of the fixed baffle, realizing rapid positioning and installation; at the same time, the positioning groove can limit the movement of the fixed baffle, thereby making the fixed baffle more stable after installation.

[0014] Preferably, a fixing groove is provided in the positioning groove, and a magnetic member is provided in the fixing groove.

[0015] By adopting the above technical solution, the fixed baffle inserted into the positioning groove is attracted by the magnetic force of the magnetic part, which facilitates the rapid installation of the fixed baffle and further restricts the movement of the fixed baffle, thereby making the fixed baffle more stable.

[0016] Preferably, a support column is provided between the first steel column and the second steel column, and between the second steel column and the third steel column.

[0017] By adopting the above technical solution, during construction, workers need to lay wire mesh on the variable steel frame for workers to stand on the variable steel frame. Since there are no obstacles between steel column one, steel column two, and steel column three, there is a lack of support when laying the wire mesh, which can easily cause safety problems. Therefore, a support column is placed obliquely between steel column one and steel column two, and between steel column two and steel column three. At the same time, the support columns can also reinforce the variable steel frame, making the variable steel frame more solid.

[0018] Preferably, reinforcement plates are provided at the connections between the steel beam 1, steel beam 2 and the steel column 1, steel column 2 and steel column 3.

[0019] By adopting the above technical solution, setting up reinforcement plates can make the connection between steel beam one, steel beam two and steel column one, steel column two and steel column three more secure, thereby making the overall displaced steel frame more durable and safer; at the same time, the reinforcement plates can also provide certain support for the wire mesh.

[0020] Preferably, positioning columns are provided on the reinforcement plates at the connections between the steel beams 1 and 2 and the steel columns 1 and 3.

[0021] By adopting the above technical solution, a rope can be tied to the positioning column to pull the displacement steel frame, and it can also be used to fix the safety rope; and because the positioning column is close to the catwalk guardrail, it can be used to position the catwalk guardrail, playing a certain auxiliary role in erecting the catwalk guardrail.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Four positioning blocks are installed on both sides of the steel beam 1, corresponding to the load-bearing cables. Four limit blocks are evenly installed on both sides of the steel beam 2. The load-bearing cables first abut against the positioning blocks, then move to abut against the limit blocks. The limit blocks evenly distribute the load-bearing cables. U-shaped locks are then used to secure the load-bearing cables so that they meet the requirements for erecting the catwalk.

[0024] 2. Fixed baffles are installed at the corresponding positioning blocks and limit blocks on Steel Beam 1 and Steel Beam 2. They can serve as safety devices in the event of failure of the U-shaped lock, preventing the displaced steel frame from falling directly and causing safety accidents. Fixed slots for the fixed baffles are set on Steel Beam 1 and Steel Beam 2, making the installation of the fixed baffles faster and more stable.

[0025] 3. Reinforcement plates are installed at the connections between steel beam 1, steel beam 2 and steel column 1, steel column 2 and steel column 3 to improve the stability of the connection and make the steel frame more durable. BRIEF DESCRIPTION OF THE DRAWINGS

Since the positions of the limit blocks 121 are dispersed, the load-bearing cables 2 are evenly dispersed after passing through the limit blocks 121, meeting the needs of setting up the catwalk; a group of two fixing holes 31 are provided on the steel beam 1 11 and the steel beam 2 12 corresponding to each load-bearing cable 2, and the U-shaped lock buckle 3 is installed and buckled on the load-bearing cable 2, and is connected and fixed with the nut through the two fixing holes 31, so that the load-bearing cable 2 is fixed on the steel beam 1 11 and the steel beam 2 12, so that the displacement steel frame will not be separated from the load-bearing cable 2.

[0033] Reference Figure 2 A guide fillet 1111 and a guide fillet 2 1211 are respectively provided on the side where the positioning block 111 and the limiting block 121 are in contact with the load-bearing cable 2, thereby reducing the friction between the load-bearing cable 2 and the positioning block 111 and the limiting block 121, making it convenient to install the load-bearing cable 2 while avoiding safety problems caused by large wear between the load-bearing cable 2 and the positioning block 111 and the limiting block 121.

[0034] Reference Figure 1, a fixed baffle 4 is installed on the steel beam 11 corresponding to the four positioning blocks 111, and a total of two fixed baffles 4 are installed; since the spacing between the limit blocks 121 on the steel beam 2 12 is large, a fixed baffle 4 is installed on the steel beam 2 12 corresponding to every two limit blocks 121, and a total of four fixed baffles 4 are installed. The fixed baffles 4 are fixed to the steel beam 1 11 and the steel beam 2 12 through threaded connections. The installation of the fixed baffles 4 prevents the steel frame 1 from directly detaching from the load-bearing cable 2 and causing a safety accident when the U-shaped lock 3 fails, and plays a role of insurance; on the steel beam 1 1. A positioning groove 41 is provided at the position where the steel beam 12 fits the fixed baffle 4. The fixed baffle 4 can be inserted into the positioning groove 41 to achieve quick positioning and installation. At the same time, the positioning groove 41 can also limit the movement of the fixed baffle 4, so that the fixed baffle 4 is installed more stably; a fixing groove 411 is provided at the bottom of the positioning groove 41, and a magnetic part 412 is installed in the fixing groove 411. The magnetic part 412 is a magnet. The fixed baffle 4 is installed by adsorption using the magnetic force of the magnetic part 412, which facilitates the quick installation of the fixed baffle 4 and also makes the installation of the fixed baffle 4 more stable.

[0035] Reference Figure 1 A tilted support column 5 is installed between the first steel column 13 and the second steel column 14, and between the second steel column 14 and the third steel column 15. Since workers need to stay on the steel frame 1 during construction, a wire mesh (not shown in the figure) is laid on the steel frame 1 for workers to stand on the steel frame 1. The support columns 5 are set to provide support for the laid wire mesh to avoid safety accidents caused by insufficient bearing capacity. At the same time, the support columns 5 can also improve the firmness of the steel frame 1, making the steel frame 1 stronger and more durable.

[0036] Reference Figure 1 , reinforcement plates 6 are installed at the connections between steel beam 11, steel beam 2 12 and steel column 1 13, steel column 2 14, steel column 3 15. The reinforcement plates 6 can not only increase the connection strength between steel beam 1 11, steel beam 2 12 and steel column 1 13, steel column 2 14, steel column 3 15, but also provide certain support for the laying of wire mesh; positioning columns 7 are provided on the reinforcement plates 6 at the connections between steel beam 1 11, steel beam 2 12 and steel column 1 13, steel column 3 15. At this time, the positioning columns 7 are located around the steel frame 1, which can be used for rope binding to pull the steel frame 1. At the same time, they can be used to fix safety ropes and assist in positioning the catwalk guardrail when erecting the catwalk guardrail.

[0037] The implementation principle of the embodiment of this application is:

[0038] First, the four load-bearing cables 2 on each side are respectively pressed against the guide fillet 1111 on one side of the positioning block 111 to initially disperse the load-bearing cables 2. Then, the load-bearing cables 2 are respectively pulled to one side of the limit block 121 and pressed against the guide fillet 2 1211. At this time, since the limit blocks 121 are evenly distributed, the load-bearing cables 2 are also evenly dispersed, meeting the needs of setting up the catwalk. After the positioning of the load-bearing cables 2 is completed, the U-shaped lock 3 is used to fix the steel frame 1 on the load-bearing cables 2 to prevent the steel frame 1 from falling off the load-bearing cables 2.

[0039] Then install the fixed baffle 4, insert the two ends of the fixed baffle 4 into the positioning groove 41, the magnetic part 412 in the positioning groove 41 can assist the fixed baffle 4 to be inserted into the positioning groove 41, and the fixed baffle 4 is connected to the steel beam 11 and the steel beam 2 12 using threads.

[0040] Then, a wire mesh is laid for the workers to stay, and the support columns 5 are used for support. The reinforcement plates 6 can also play a certain supporting role. Ropes are then tied to the positioning columns 7 to control the slippage of the steel frame 1 on the load-bearing cables 2. At the same time, the workers' safety ropes can also be fixed to the positioning columns 7 through ropes. At this time, the workers can implement the catwalk erection operation on this displaced steel frame.
