Description

Technical Field

[0001] This utility model relates to the field of edge protection technology, specifically to an edge protection structure for railway platforms. Background Technology

[0002] With the rapid development of railway transportation, railway platforms, as important places for passengers to board and alight from trains, are of paramount importance in terms of safety and stability. However, traditional railway platform edge protection structures mostly adopt fixed structures, such as concrete capstones or granite surfacing layers. These construction methods often have significant limitations in dealing with factors such as foundation settlement and overhead compaction.

[0003] Chinese Patent Publication No. CN220815005U discloses a construction edge protection structure, including two mounting plates. Each mounting plate has a cavity inside, and a first threaded rod is fixedly connected inside the cavity. Two nuts are threaded onto the first threaded rod. This invention involves moving a first sliding block and a clamping plate towards a column until the clamping plate contacts the column. Then, the nuts are rotated clockwise on the first threaded rod, causing the nuts to move towards the clamping plate until they are tightly pressed against it. At this point, the position of the first sliding block and the clamping plate is limited by the nut, completing the installation of the mounting plates. Next, the extension rod and the vertical plate are moved by rotating the second threaded rod until the locking block enters the locking groove, completing the installation of the telescopic component. The entire protective structure is then installed. During installation, no drilling is required on the building's floor slab, thus avoiding damage to the building's floor structure.

[0004] When implementing the above solution, the applicant found that when the edge protection structure needs to be moved to another location for use, its large size increases the difficulty of handling for staff. Moreover, the edge protection structure does not have the function of being moved and fixed, which results in a lot of time being spent when moving the protection structure, thereby reducing the convenience of handling the device. Based on this, this utility model designs an edge protection structure for railway platforms to solve the above problems. Utility Model Content

[0025] 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.

[0026] Please refer to Figures 1-4A railway platform edge protection structure includes: a transport box 1, in which pulleys 2 are installed in the inner cavity of the transport box 1, the pulleys 2 are arranged in four sets in a rectangular array, and a protective plate 3 is installed on the top of the transport box 1; a retraction mechanism, located in the inner cavity of the transport box 1 and used for retracting the pulleys 2; the retraction mechanism includes a rotating component and an adjusting component, the rotating component is located in the inner cavity of the transport box 1 and used to drive the adjustment component to change, the adjusting component is located on the outer ring of the rotating component and used to drive the retraction of the pulleys 2; and a lifting mechanism, located on the top of the transport box 1 and used for adjusting the height of the protective plate 3.

[0027] The rotating assembly includes a rotating hole 4 on one side of the transport box 1. A rotating rod 5 is installed in the inner cavity of the rotating hole 4. A rotating handle 6 is installed on the left side of the rotating rod 5, and a first bidirectional lead screw 7 is installed on the right side of the rotating rod 5. The adjusting assembly includes an adjusting block 8 installed on the outer ring of the first bidirectional lead screw 7. A fixing block 9 is installed in the inner cavity of the transport box 1. Two sets of adjusting blocks 8 are symmetrically distributed. A first rotating plate 10 is hinged to the bottom of the adjusting block 8. A second rotating plate 11 is hinged to the inner cavity of the fixing block 9. The first rotating plate 10 and the second rotating plate 11 are rotatably connected by a hinge. A pulley 2 is installed at the bottom of the hinge. A limiting assembly is installed in the inner cavity of the transport box 1. The limiting assembly includes a limiting rod 13 installed in the inner cavity of the transport box 1. Two sets of limiting rods 13 are symmetrically distributed and are inserted into the inner cavity of the adjusting block 8.

[0028] In this embodiment of the invention, rotating the handle 6 drives the rotating rod 5 to rotate, which in turn drives the first bidirectional lead screw 7 to rotate, causing the adjusting block 8 to move on the outer ring of the first bidirectional lead screw 7, thereby changing the included angle between the first rotating plate 10 and the second rotating plate 11.

[0029] Please refer to Figures 1-4 The lifting mechanism includes a mounting base 14 installed on the top of the transport box 1. Four sets of mounting bases 14 are arranged in a rectangular array. A lifting motor 15 is installed in the inner cavity of the mounting base 14 located on the front side. A second bidirectional lead screw 16 is installed on the back of the output shaft of the lifting motor 15. A moving block 17 is threaded onto the outer ring of the second bidirectional lead screw 16. A linkage assembly is also installed on the top of the moving block 17. The linkage assembly includes a rotating plate 18 hinged to the top of the mounting base 14. A lifting plate 19 is provided on the top of the rotating plate 18. A slider 20 is hinged to the top of the rotating plate 18. A groove 21 is provided at the bottom of the lifting plate 19. The slider 20 slides within the inner cavity of the groove 21. A telescopic rod is installed between the lifting plate 19 and the transport box 1.

[0030] The top of the lifting plate 19 is connected to the bottom of the protective plate 3, and warning lights 22 are installed on both the front and back of the protective plate 3.

[0031] In this embodiment of the utility model, the lifting motor 15 drives the second bidirectional lead screw 16 to rotate, causing the moving block 17 to move on the outer thread of the second bidirectional lead screw 16. The rotating plate 18 rotates under the drive of the moving block 17, and then, through the cooperation of the slider 20 and the slide groove 21, the lifting plate 19 is pushed to rise or fall smoothly.

[0032] In use, the transport box 1 can be easily moved on the ground via four sets of pulleys 2 installed in its inner cavity, facilitating the transport of the protective structure to the designated location. The pulleys 2 not only improve the ease of movement of the equipment but also ensure stability during movement through their rectangular array distribution.

[0033] The retraction mechanism plays a crucial role when the equipment needs to be moved to other locations requiring protection. Rotating the handle 6 drives the rotating rod 5 to rotate, which in turn drives the first bidirectional lead screw 7 to rotate, causing the adjusting block 8 to move on the outer ring of the first bidirectional lead screw 7, thereby changing the angle between the first rotating plate 10 and the second rotating plate 11. Since the pulley 2 is installed at the bottom of the hinge, it can retract as the angle changes. Simultaneously, the limiting rod 13 in the limiting assembly is inserted into the inner cavity of the adjusting block 8, ensuring the stability of the adjusting block 8 during movement and preventing it from shifting or wobbling.

[0034] The lifting mechanism is used to adjust the height of the protective plate 3 to adapt to different platform heights or protection requirements. The lifting motor 15 drives the second double-acting screw 16 to rotate, causing the moving block 17 to move on the outer thread of the second double-acting screw 16. This motion is converted into the lifting motion of the lifting plate 19 through the linkage assembly. The rotating plate 18 rotates under the drive of the moving block 17, and then, through the cooperation of the slider 20 and the slide 21, the lifting plate 19 is pushed to rise or fall smoothly. The extension rod enhances the connection stability between the lifting plate 19 and the transport box 1.

[0035] Finally, the protective plate 3 is fixed to the top of the lifting plate 19, and its height is adjusted as the lifting plate 19 rises and falls. The warning lights 22 on the front and back of the protective plate 3 serve as reminders and warnings, ensuring that construction workers and passengers can clearly see the protective structure at night or in low-light environments, thereby avoiding accidents.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
