Description

Technical Field

[0001] The utility model relates to the technical field of subway safety facilities, in particular to a subway station steel structure emergency platform. Background Art

[0002] The subway tunnel emergency tread is a safety facility designed for use in emergency situations. It is usually installed in subway tunnels so that passengers can quickly evacuate to the nearest station or safe exit when the train stops running.

[0003] The existing subway station steel structure emergency platform does not have an auxiliary support structure during use. The emergency platform is usually directly installed on the inner wall surface of the subway tunnel. In an emergency, many people walk on the surface of the emergency platform, and the emergency platform is prone to deformation or damage, thereby affecting evacuation efficiency and personnel safety.

[0004] In order to solve the above technical problems, we designed a subway station steel structure emergency platform. Utility Model Content

[0005] The utility model aims to provide a steel structure emergency platform for a subway station, which has the advantages of an auxiliary support structure and is convenient for disassembling and replacing step plates, thereby solving the problem that the bottom of the existing emergency platform does not have an auxiliary support structure during use, and it is not convenient for users to quickly disassemble and replace the step plates when they are damaged.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a subway station steel structure emergency platform, comprising square steel, cross bars are riveted on opposite sides of the square steel, support plates are welded on both sides of the cross bars, a step plate is placed on the top of the support plate, grooves are provided on both sides of the top of the step plate, springs are fixedly connected on the opposite side of the inner cavity of the groove, adjustment plates are riveted on the opposite ends of the springs, positioning blocks are riveted on the opposite sides of the adjustment plates, positioning grooves are provided on both sides of the cross bars, and a support mechanism is threadedly connected to the bottom of the front square steel, the support mechanism comprises a threaded rod, and a support tube is riveted to the bottom end of the threaded rod.

[0007] Preferably, the top end of the threaded rod is threadedly connected to the square steel, the inner cavity of the support tube is threadedly connected to a screw rod, the bottom end of the screw rod is welded to a support plate, and a mounting hole is opened on the top of the support plate.

[0008] Preferably, the bottom of the positioning block is provided with an oblique angle, and the opposite ends of the positioning block penetrate the step plate and extend to the inner cavity of the positioning groove.

[0009] Preferably, a groove is provided on the top of the adjustment plate, and a first fixing plate is welded to the bottom of the square steel on the rear side.

[0010] Preferably, the front side and the rear side of both sides of the top of the step plate are provided with limiting grooves, and a baffle is placed inside the limiting groove, and the baffle is located at the top of the groove.

[0011] Preferably, a reinforcing rib is welded to the bottom of the crossbar, and a second fixing plate is welded to the rear end of the reinforcing rib.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the advantage of auxiliary support function through the cooperation of square steel and supporting mechanism. After the installation of the square steel on the rear side is completed, the threaded rod is installed at the bottom of the square steel on the front side, and then the height of the support plate is adjusted according to the distance from the ground. At this time, the support plate is rotated, and the support plate drives the screw rod to rotate. The screw rod is connected with the support pipe thread to make the screw rod and the support plate move downward. After the support plate contacts the ground, it is fixed by bolts and mounting holes.

[0014] 2. The utility model has the advantage of easy replacement of the step plate through the cooperation of the groove, spring, adjustment plate, positioning block and positioning groove. When the step plate is damaged, remove the baffle plate, pull the adjustment plate through the groove, and the adjustment plate compression spring drives the positioning block to move. One end of the positioning block is away from the positioning groove. At this time, the step plate is released from the limit, and then the step plate can be disassembled and replaced.

[0023] See also Figure 1 and Figure 5 The top of the threaded rod 11 is threadedly connected to the square steel 1, the inner cavity of the support tube 12 is threadedly connected to the screw rod 13, the bottom end of the screw rod 13 is welded to the support plate 14, and the top of the support plate 14 is provided with a mounting hole 15. By setting the mounting hole 15, the support plate 14 can be installed and fixed so that it will not rotate.

[0024] See also Figure 6 The bottom of the positioning block 8 is provided with an oblique angle. By setting the oblique angle, it is convenient to insert the positioning block 8 into the inner cavity of the positioning groove 9, thereby improving the installation efficiency. The opposite ends of the positioning block 8 penetrate the step plate 4 and extend to the inner cavity of the positioning groove 9.

[0025] See also Figure 5 and Figure 6 A groove 16 is provided on the top of the adjusting plate 7. The groove 16 is provided to facilitate the user to pull the adjusting plate 7. A first fixing plate 17 is welded to the bottom of the rear square steel 1.

[0026] See also Figure 1 and Figure 6 Limiting grooves 18 are provided on the front and rear sides of both sides of the top of the step plate 4, and baffles 19 are placed inside the limiting grooves 18. By setting the baffles 19, the groove 5 can be shielded and protected to prevent dust from entering the interior of the groove 5. The baffles 19 are located at the top of the groove 5.

[0027] See also Figure 5A reinforcing rib 20 is welded to the bottom of the cross bar 2. By providing the reinforcing rib 20, the bottom of the cross bar 2 can be reinforced and supported to prevent it from breaking easily. A second fixing plate 21 is welded to the rear end of the reinforcing rib 20.

[0028] When in use, the first fixing plate 17 is connected to the inner wall of the subway tunnel by bolts, and then the reinforcing rib 20 is connected to the inner wall of the tunnel by bolts and the second fixing plate 21. At this time, the installation of the emergency platform is completed. When reinforcement support is needed, the threaded rod 11 is installed at the bottom of the square steel 1 on the front side, and then the height of the support plate 14 is adjusted according to the distance from the ground. At this time, the support plate 14 is rotated, and the support plate 14 drives the screw rod 13 to rotate. The screw rod 13 is threadedly connected with the support tube 12 to make the screw rod 13 and the support plate 14 move downward. After the support plate 14 contacts the ground, the support plate 14 is fixed by bolts and mounting holes 15. When the step plate 4 is damaged, the baffle 19 is removed, and the adjustment plate 7 is pulled through the groove 16.
