Description

Technical Field

[0001] The utility model belongs to the technical field of subway equipment, and in particular relates to an evacuation platform used in a subway system. Background Art

[0002] As a vital means of transportation in modern cities, subways carry large numbers of people, and their safety is directly related to the lives of passengers. During subway operations, various emergencies may occur, such as equipment failure, fire, and earthquakes. These situations can prevent trains from continuing in tunnels, necessitating the evacuation of passengers from the trains within the tunnels. To ensure passenger safety, subway systems require specialized evacuation facilities, and subway evacuation platforms have emerged as a result.

[0003] Advances in materials science and improved manufacturing processes have optimized the materials and structures of subway evacuation platforms, making them stronger, more durable, and easier to install. The evacuation platform primarily consists of a platform tread and brackets. Due to the presence of wind loads on the piston, the platform treads and brackets require a secure connection. Traditional connection methods typically use bolts to limit the impact of wind loads on the evacuation platform system. However, in the dark and humid environment of tunnels, bolts are susceptible to corrosion, shortening the system's service life. Bolt installation is also cumbersome, increasing the workload, delaying construction progress, and increasing project costs. Therefore, improvements are necessary. Utility Model Content

[0034] Example: Evacuation platform for subway system, see Figure 1-4 As shown, it includes platform pedal I 1, platform pedal II 2, bracket 3, embedded sleeve 4, connecting rod 5, and limiting ring 6;

[0035] The platform pedal I1 and the platform pedal II2 are spliced ​​into an evacuation platform panel, and brackets 3 are provided at the joints of the platform pedal I1 and the platform pedal II2 and at the edges on both sides of the evacuation platform panel. Embedded sleeves 4 are provided at the connections among the platform pedal I1, the platform pedal II2 and the bracket 3, as well as at the connections between the platform pedal and the bracket 3. The connecting rod 5 is inserted into the embedded sleeve 4 and rotated so that the toothed parts therebetween cooperate with each other. The limiting ring 6 is inserted into the limiting gap between the embedded sleeve 4 and the connecting rod 5 to limit the annular displacement of the connecting rod 5.

[0036] In this embodiment, the embedded sleeve, connecting rod and limiting ring cooperate with each other to replace the role of bolts in the evacuation platform system. Compared with bolt connection, it has good corrosion resistance, is not afraid of dark and humid environments, and improves the service life of the evacuation platform system; the construction and installation are simple, which greatly reduces the labor intensity of workers and shortens the construction period.

[0037] In a specific embodiment: see Figure 8 As shown, the platform pedal I1, platform pedal II2, and the connection parts on the bracket 3 are all provided with holes for installing the embedded sleeve 4, the embedded sleeve 4 is embedded in the hole, and the outer circle of the embedded sleeve 4 is provided with an external screw groove 4-1 for increasing the embedded pulling force.

[0038] In the above embodiment, the embedded sleeve 4 is embedded in the holes of the platform pedal I1, the platform pedal II2 and the bracket 3. The outer screw groove of the embedded sleeve is used to increase the pulling force between the embedded sleeve and the bracket.

[0039] In a specific embodiment: see Figure 8-11As shown, arc tooth grooves 4-2 are symmetrically provided on both sides of the inner circumference of the embedded sleeve 4, and there are no arc tooth grooves on the other symmetrical sides of the inner circumference of the embedded sleeve 4, forming a vacant position I4-3; arc tooth teeth 5-1 are symmetrically provided on both sides of the outer circumference of the connecting rod 5, and there are no arc tooth teeth on the other symmetrical sides of the outer circumference of the connecting rod 5, forming a vacant position II5-2.

[0040] In this embodiment, the connecting rod 5 is inserted into the embedded sleeve 4 and rotated so that the arc teeth 5-1 and the arc tooth grooves 4-2 engage with each other to form a toothed structure that cooperates with each other. At the same time, the free position II5-2 of the connecting rod 5 corresponds to the free position I4-3 of the embedded sleeve 4 to form a limiting gap.

[0041] In a specific embodiment: see Figure 12-13 As shown, the limiting ring 6 includes a circular ring body 6-1, and arc limiting plates 6-2 are symmetrically provided on both sides of the circular ring body 6-1. The arc limiting plates 6-2 are used to be inserted into the limiting gap formed by the vacant position II5-2 and the vacant position I4-3 to limit the annular displacement of the connecting rod 5.

[0042] In a specific embodiment: see Figure 13 As shown, the lower edge of the inner circle of the annular body 6-1 is provided with a buckling edge 6-3 for buckling and connecting with the connecting rod 5, and the upper end surface of the connecting rod 5 is provided with a reverse tooth structure 5-3 for buckling with the buckling edge 6-3.

[0043] In a specific embodiment: see Figure 5-7 As shown, the platform pedal I1 and the platform pedal II2 are both provided with splicing edges on their edges; the bracket 3 is a hook-shaped structure composed of a horizontal beam and an inclined beam.

[0044] Preferably, the embedded sleeve 4 and the connecting rod 5 are made of high-strength nylon material, which has good strength and corrosion resistance. The limiting ring 6 is made of polyester elastomer, which has excellent corrosion resistance and a certain elasticity, making it convenient for construction and installation.

[0045] During installation of this evacuation platform, embedded sleeves 4 are installed at the connections between platform tread Ⅰ1, platform tread Ⅱ2, and bracket 3, as well as at the connection between the platform tread and bracket 3. The embedded sleeves 4 embedded in the three parts are aligned vertically on the same axis. Connecting rod 5 is then inserted into embedded sleeve 4 and rotated 90°, so that the teeth on connecting rod 5 cooperate with the teeth inside embedded sleeve 4, limiting the vertical displacement of bracket 3, platform tread Ⅰ1, and platform tread Ⅱ2. Finally, a limiting ring 6 is inserted into the empty space within the embedded sleeve and snapped into the inverted teeth on the top of connecting rod 5, limiting the circumferential displacement of connecting rod 5 within embedded sleeve 4. The embedded sleeve 4, connecting rod 5, and limiting ring 6 cooperate to limit the vertical and horizontal displacement of platform tread Ⅰ1, platform tread Ⅱ2, and bracket 3.

[0047] Step 1: Make the embedded sleeves in the platform pedal I, platform pedal II and bracket on the same axis;

[0048] Step 2: Insert the connecting rod into the embedded sleeve until it reaches the bottom, and rotate it 90° so that its tooth structure is completely hidden in the annular gap inside the embedded sleeve;

[0049] Step 3: Insert the limit ring into the empty space in the embedded sleeve to completely limit the rotational displacement of the connecting rod, and press the top so that it is buckled against the top of the connecting rod and flush with the surface of the platform pedal.
