[0024] Refer to Figures 1-6 :

[0025] An embodiment of the present utility model provides a personnel safety rescue platform board for a subway tunnel, which includes a main body unit 100 and a mounting unit 200. The main body unit 100 includes a tunnel side wall 101 and a plurality of support plates 102. One side of the support plate 102 is fixed with an embedded plate 103. The side of the embedded plate 103 away from the support plate 102 is fixed with a clamping plate 105. A plurality of convex ribs 104 are fixed to the top and bottom of the embedded plate 103. A fixing member for fixing the embedded plate 103 and the clamping plate 105 is arranged in the tunnel side wall 101. A plurality of tread plates 108 and two auxiliary plates 109 are arranged on the top of the support plate 102. The two auxiliary plates 109 are respectively laid on the first and last support plates 102. The plurality of tread plates 108 are sequentially laid on the support plates 102. The mounting unit 200 includes two grooves 202 opened in the support plate 102. Vertical plates 201 are fixed to both ends of the bottom of the tread plate 108 and the bottom of the auxiliary plate 109. The vertical plates 201 can penetrate through the grooves 202 and slide in the grooves 202. A positioning assembly for positioning between the tread plates 108 and the auxiliary plates 109 and between adjacent tread plates 108 is arranged below the support plate 102.

[0026] Among them, the fixing member includes a pre-embedded groove 106 and a clamping groove 107 opened in the tunnel side wall 101, and the pre-embedded groove 106 and the clamping groove 107 are communicated. The clamping plate 105 can be embedded into the clamping groove 107, the embedded plate 103 can be embedded into the pre-embedded groove 106, and the pre-embedded groove 106 can be filled with concrete.

[0027] During use, first install the support plate 102. By embedding the clamping plate 105 into the clamping groove 107, at this time the embedded plate 103 is located in the pre-embedded groove 106, and then fill the pre-embedded groove 106 with concrete, so as to complete the installation of the support plate 102. Due to the arrangement of the convex ribs 104, the grasping force between the embedded plate 103 and the concrete can be improved, that is, the firmness of the support plate 102 is improved.

[0028] In addition, the positioning assembly includes a plurality of rectangular frames 203. Two positioning plates 204 are slidably connected in the rectangular frames 203. A positioning groove 205 is opened in the vertical plate 201. The positioning plates 204 can be embedded into the positioning groove 205. Two springs 208 are arranged in the rectangular frames 203, and the two ends of the springs 208 respectively abut against the two positioning plates 204. A travel groove 206 is opened at the bottom of the rectangular frame 203. A lever 207 is fixed to the bottom of the positioning plate 204, and the lever 207 is slidably matched in the travel groove 206.

[0029] In use, after the support plate 102 is installed, the pedals 108 are laid flat on the support plate 102 one by one, so that the vertical plates 201 are embedded into the grooves 202. At this time, the auxiliary plates 109 are laid flat on the two end support plates 102, so that the vertical plates 201 at the bottom of the auxiliary plates 109 penetrate through the grooves 202 in the two end support plates 102. Then, the two lever rods 207 are moved closer to each other, so that the positioning plate 204 moves into the rectangular frame 203. Then, the rectangular frame 203 is moved under the support plate 102, so that the top of the rectangular frame 203 is in contact with the bottom of the support plate 102. Then, the lever rods 207 are released, and the positioning plate 204 is driven by the resilience of the spring 208 to be embedded into the positioning groove 205, so that the vertical plate 201 is fixed to the support plate 102, that is, the pedal 108 is installed. This installation method is not only convenient, but also will not loosen due to vibration.

[0030] In the foregoing, the exemplary embodiments of the solutions proposed in the present disclosure have been described in detail with reference to the preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed in the present disclosure can be made without exceeding the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
