Description

Technical Field

[0001] The utility model relates to the field of rail transit construction, and particularly relates to a safety platform for single-track beam erection. Background Technique

[0002] Maglev track lines are divided into single-track and double-track. The double-track can allow two trains to pass in both directions, while the single-track railway can only allow one train to pass in one direction. The double-track is actually two parallel track lines respectively erected on two parallel crossties, while the single-track is a single track erected on a single crosstie. The crosstie of the single-track is called a single-track beam, and the single-track beam is erected on the pier. The single-track beam of the medium and low-speed maglev track is very narrow. Since the single-track beam is erected in mid-air, there is no working space for construction workers during the construction of the single-track. Therefore, a safety platform must be built on the single-track beam to facilitate the construction of the workers and ensure the safety of the construction workers at the same time.

[0003] According to the Chinese patent with the publication number CN204959505U, a single-track beam safety platform is disclosed. The maglev track single-track beam safety platform provided by this utility model uses a structure of a load-bearing steel beam and a wooden board laid on a steel mesh, and a protective device is also provided on the side of the horizontal platform, which can prevent workers from falling while providing a working platform for the workers, effectively ensuring the safety of the construction workers.

[0004] Regarding the above-mentioned disclosed patent content, by setting up a grid, an installation pipe and a plug rod, the plug rod at the bottom of the grid can be inserted into the installation pipe, so as to complete the positioning and installation of the grid. However, this method only limits the grid by the matching of the plug rod and the installation pipe, resulting in the grid may move after being vibrated or collided during work, thereby reducing the stability of the grid after installation, making it difficult for the grid to play a stable protective role, and thus reducing the use effect of the installation platform. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a safety platform for single-track beam erection to solve the technical problem of poor stability of the grid after being installed by plugging.

[0006] To achieve the above object, the utility model provides the following technical solution: A safety platform for single-line beam erection, including a single-line beam main body, a plurality of load-bearing steel beams are arranged at intervals on the top of the single-line beam main body, and positioning plates are installed on both sides of the load-bearing steel beams. A slot and a clamping component are arranged in the positioning plate. An insertion plate is inserted into the slot. The clamping component includes a groove opened on one side inside the positioning plate and a clamping slot opened on one side of the insertion plate. A first spring is installed inside the groove, and one end of the first spring is connected to a clamping block extending into the clamping slot. One side of the clamping block is installed with a pull rod penetrating to the outside of the positioning plate. A grid is installed on the top of every two insertion plates, and a stabilizing component is arranged on the top of the grid. The stabilizing component includes a rotating shaft arranged on one side of the top of the grid through a bearing and a cavity opened on the other side of the top of the grid. The end of the rotating shaft is connected to a limiting plate, and a limiting hole is opened on the limiting plate.

[0007] By adopting the above technical solution, when installing the grid, the insertion plate at the bottom of the grid can be inserted into the slot to position the grid. When the clamping block is inserted into the clamping slot, the insertion plate can be locked to prevent the insertion plate from moving.

[0008] Further, a second spring is installed inside the cavity, and the end of the second spring is connected to a limiting rod extending to the outside of the grid. One side of the limiting rod is connected to a pushing plate.

[0009] By adopting the above technical solution, the staff can push the limiting rod to move through the pushing plate, so that the limiting rod moves out of the limiting hole and no longer limits the limiting plate. At this time, the limiting plate can be rotated and the grid can be disassembled.

[0010] Further, one end of the pull rod is connected to a pulling plate, and the clamping block is adapted to the clamping slot.

[0011] By adopting the above technical solution, it is convenient for the staff to pull the pull rod through the pulling plate. When the pull rod moves, it will drive the clamping block to move, so that the clamping block moves into the groove.

[0012] Further, the limiting rod is adapted to the limiting hole, and the limiting rod is slidably connected to the cavity.

[0013] By adopting the above technical solution, when the limiting rod moves into the limiting hole, the limiting plate can be locked, and then two adjacent grids can be stably connected together.

[0014] Further, a steel bar mesh is laid on the load-bearing steel beam, and a wooden board is laid on the steel bar mesh.

[0015] By adopting the above technical solution, the steel bar mesh can support the wooden board, and at the same time, it is convenient for the staff to stand on the wooden board to work or rest, improving the safety of the platform.

[0016] Further, a reinforcing plate is fixed to the bottom of the load-bearing steel beam, and one side of the reinforcing plate is closely attached to the main body of the single-line beam.

[0017] By adopting the above technical solution, the stability of the load-bearing steel beam is improved.

[0018] Further, a protective net is provided inside the grid.

[0019] By adopting the above technical solution, the protective net can play a protective role, preventing the staff from falling from the platform, thereby improving the safety of the platform.

[0020] Further, the tops of the clamping blocks and the bottoms of the inserting plates are both arranged in an inclined shape.

[0021] By adopting the above technical solution, when the inserting plate is inserted into the slot, the inserting plate can push the clamping block to move, so that the clamping block moves into the groove and compresses the first spring.

[0022] Further, the grid is detachably connected to the positioning plate through the inserting plate, and the inserting plate is adapted to the slot.

[0023] By adopting the above technical solution, when disassembling the grid, the grid can be lifted upward, so that the inserting plate is removed from the slot, thus facilitating the removal of the grid.

[0024] Further, the limiting plate is rotatably connected to the grid through a rotating shaft, and the limiting rod is slidably connected to the cavity.

[0025] By adopting the above technical solution, it is convenient to rotate the limiting plate. When the limiting rod moves into the cavity, the limiting rod will compress the second spring, causing the second spring to contract.

[0026] To sum up, the main beneficial effects of the present utility model are as follows:

[0027] 1. By providing a clamping component in the present utility model, when installing the grid, the staff can insert the inserting plate at the bottom of the grid into the slot to position the grid. When the inserting plate is inserted, since the bottom of the inserting plate and the top of the clamping block are arranged in an inclined shape, the inserting plate will push the clamping block to move, so that the clamping block moves into the groove and compresses the first spring. When the inserting plate is completely inserted into the slot, at this time, the clamping block is aligned with the clamping groove, and the first spring stretches and then pushes the clamping block to move back to its original position, so that the clamping block is clamped into the clamping groove and locks the inserting plate to prevent the inserting plate from moving. In this way, the installation of the grid can be completed, preventing the grid from shaking and improving the stability of the grid;

[0028] 2. The utility model is provided with a stabilizing component. After the grid frame is installed, the staff can rotate the limiting plate and push the limiting rod through the pushing plate, so that the limiting rod moves into the cavity and compresses the second spring. When the limiting plate rotates until the limiting hole aligns with the limiting rod, stop rotating the limiting plate. At this time, release the limiting rod, and the second spring stretches and then pushes the limiting rod upward, so that the limiting rod moves into the limiting hole to limit and fix the limiting plate. In this way, two adjacent grid frames can be stably connected, thereby improving the stability of the grid frame. Moreover, the protective structure is composed of multiple grid frames with smaller sizes, which makes it convenient for handling and installation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0038] The embodiments of the present utility model will be described below according to its overall structure.

[0039] Embodiment 1:

[0040] A safety platform for single-line beam erection, as Figures 1 - 7 shown, includes a single-line beam main body 1. A plurality of load-bearing steel beams 2 are arranged at intervals on the top of the single-line beam main body 1. Positioning plates 6 are installed on both sides of the load-bearing steel beams 2. A slot 7 and a clamping component 9 are provided inside the positioning plate 6. An insertion plate 8 is inserted into the inside of the slot 7. A steel mesh 3 is laid on the load-bearing steel beams 2, and a wooden board 4 is laid on the steel mesh 3. The steel mesh 3 can support the wooden board 4 and at the same time facilitate the staff to stand on the wooden board 4 for operation or rest, improving the safety of the platform. A reinforcing plate 5 is fixed to the bottom of the load-bearing steel beam 2. One side of the reinforcing plate 5 is closely attached to the single-line beam main body 1, improving the stability of the load-bearing steel beam 2. The grid 10 is detachably connected to the positioning plate 6 through the insertion plate 8. The insertion plate 8 is adapted to the slot 7. When disassembling the grid 10, the grid 10 can be lifted upward so that the insertion plate 8 is removed from the inside of the slot 7, thus facilitating the removal of the grid 10.

[0041] Specifically, the clamping component 9 includes a groove 903 opened on one side inside the positioning plate 6 and a clamping groove 901 opened on one side of the insertion plate 8. A first spring 904 is installed inside the groove 903, and one end of the first spring 904 is connected to a clamping block 902 extending into the inside of the clamping groove 901. A pull rod 905 penetrating to the outside of the positioning plate 6 is installed on one side of the clamping block 902. One end of the pull rod 905 is connected to a pull plate 906. The clamping block 902 is adapted to the clamping groove 901, facilitating the staff to pull the pull rod 905 through the pull plate 906. When the pull rod 905 moves, it will drive the clamping block 902 to move, so that the clamping block 902 moves into the inside of the groove 903. A grid 10 is installed on the top of every two insertion plates 8. When installing the grid 10, the insertion plate 8 at the bottom of the grid 10 can be inserted into the inside of the slot 7 to position the grid 10. When the clamping block 902 is clamped into the inside of the clamping groove 901, the insertion plate 8 can be locked to prevent the insertion plate 8 from moving, and a stabilizing component 12 is provided on the top of the grid 10.

[0042] Specifically, the stabilizing component 12 includes a rotating shaft 1201 arranged on one side of the top of the grid frame 10 through a bearing and a cavity 1206 opened on the other side of the top of the grid frame 10. The end of the rotating shaft 1201 is connected with a limiting plate 1202, and a limiting hole 1203 is opened on the limiting plate 1202. A second spring 1207 is installed inside the cavity 1206, and the end of the second spring 1207 is connected with a limiting rod 1204 extending outside the grid frame 10. One side of the limiting rod 1204 is connected with a push plate 1205. The staff can push the limiting rod 1204 to move through the push plate 1205, so that the limiting rod 1204 moves out of the limiting hole 1203 and no longer limits the limiting plate 1202. At this time, the limiting plate 1202 can be rotated and the grid frame 10 can be disassembled.

[0043] Specifically, the limiting rod 1204 is adapted to the limiting hole 1203, and the limiting rod 1204 is slidably connected with the cavity 1206. After the limiting rod 1204 moves into the limiting hole 1203, the limiting plate 1202 can be locked, and then two adjacent grid frames 10 can be stably connected together. The limiting plate 1202 is rotatably connected with the grid frame 10 through the rotating shaft 1201, and the limiting rod 1204 is slidably connected with the cavity 1206, which is convenient for the staff to rotate the limiting plate 1202. When the limiting rod 1204 moves into the cavity 1206, the limiting rod 1204 will squeeze the second spring 1207, causing the second spring 1207 to contract.

[0044] Embodiment 2:

[0045] On the basis of the above Embodiment 1, in order to improve the safety of the staff on the platform and prevent falling, the following structure will be set up.

[0046] Refer to Figures 1 - 5 , a protective net 11 is arranged inside the grid frame 10. The protective net 11 can play a protective role to prevent the staff from falling from the platform, thereby improving the safety of the platform.

[0047] Embodiment 3:

[0048] On the basis of the above Embodiment 1, in order to facilitate the installation of the grid frame 10 without the staff pulling the pull plate 906, the following settings can be made.

[0049] Refer to Figure 6 , the tops of the clamping blocks 902 and the bottoms of the inserting plates 8 are both arranged in an inclined shape, so that when the inserting plate 8 is inserted into the slot 7, the inserting plate 8 can push the clamping block 902 to move, causing the clamping block 902 to move into the groove 903 and squeeze the first spring 904. Therefore, when the inserting plate 8 is inserted into the slot 7, the staff does not need to manually pull the pull plate 906, which is convenient for quickly installing the grid frame 10.

[0050] The working principle of the utility model is as follows: First, the staff can set the load-bearing steel beam 2 on the single-line beam main body 1, then lay the steel mesh 3 on the part where the load-bearing steel beam 2 extends from the single-line beam main body 1, then lay the wooden board 4 on the steel mesh 3, and then insert the insertion plate 8 at the bottom of the grid frame 10 into the slot 7 to position the grid frame 10. When the insertion plate 8 is inserted, since the bottom of it and the top of the clamping block 902 are arranged in an inclined plane, the insertion plate 8 will push the clamping block 902 to move, so that the clamping block 902 moves into the groove 903 and compresses the first spring 904. When the insertion plate 8 is completely inserted into the slot 7, at this time, the clamping block 902 is aligned with the clamping groove 901, and the first spring 904 stretches and then pushes the clamping block 902 to reset and move, so that the clamping block 902 is clamped into the clamping groove 901 and locks the insertion plate 8 to prevent the insertion plate 8 from moving. In this way, the installation of the grid frame 10 can be completed;

[0051] After the grid frame 10 is installed, the staff can rotate the limiting plate 1202 and push the limiting rod 1204 through the pushing plate 1205, so that the limiting rod 1204 moves into the cavity 1206 and compresses the second spring 1207. When the limiting plate 1202 rotates until the limiting hole 1203 is aligned with the limiting rod 1204, stop rotating the limiting plate 1202. At this time, release the limiting rod 1204, and the second spring 1207 stretches and then pushes the limiting rod 1204 to move upward, so that the limiting rod 1204 moves into the limiting hole 1203 to limit and fix the limiting plate 1202. In this way, two adjacent grid frames 10 can be firmly connected, and at the same time, the platform can be built, which is convenient for the staff to work on this platform. The grid frame 10 and the protection net 11 can play a protective role.
