Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to an adjustable bracket for rectifying and correcting a subway evacuation platform. Background Art

[0002] When a subway breaks down during travel, passengers in the subway workshop need to be evacuated. Therefore, it is often necessary to install an evacuation platform inside the subway tunnel for passengers to carry out emergency evacuation and take shelter. However, the existing subway evacuation platform still has some shortcomings.

[0003] Announcement No. CN 215256307 U discloses an adjustable subway evacuation platform. The adjustable subway evacuation platform is provided with evenly distributed ear plates, which can effectively improve the welding stability of the platform structure. At the same time, through the rotatable and adjustable support rods, the adjustability and installation applicability of the platform can be effectively improved. It can be pre-produced and has strong practicality.

[0004] When the above-mentioned adjustable subway evacuation platform is in use, the support rods are used to consolidate and support the support steel beams, so that the support rods correct the deviation of the support steel beams and keep the support steel beams in a horizontal state. However, the support rods and the support steel beams are fixed with bolts. During the bolt-type installation, the support steel beams need to be lifted and then rotated continuously with the help of tools. The installation time is long and the efficiency is low. The subway will vibrate when it is running. Long-term vibration will cause the bolts to loosen and fall off, resulting in poor stability. Utility Model Content

[0026] Reference Figure 1-7 :

[0027] In one embodiment of the present invention, an adjustable deviation-correcting bracket for subway evacuation platform rectification is provided, comprising a support unit 100 and a deviation-correcting unit 200. The support unit 100 comprises a support plate 101 and two mounting plates 102. Two mounting blocks 104 are fixed to one side of the support plate 101. Two ear plates 103 are fixed to the mounting plate 102. A cylindrical rod 105 is fixed in the mounting block 104, and the cylindrical rod 105 passes through the ear plate 103 and rotates with the ear plate 103. The correction unit 200 includes two rectangular frames 201 arranged at the bottom of the support plate 101, two ear plates 202 are fixed at the bottom of the rectangular frame 201, and a correction rod 204 is arranged under the ear plate 202, and a cylindrical rod 3 203 is fixed at one end of the correction rod 204, and the cylindrical rod 3 203 passes through the ear plate 3 202 and is rotatably connected to the ear plate 3 202. A fixing part for fixing the rectangular frame 201 and the support plate 101 is arranged between the rectangular frame 201 and the support plate 101.

[0028] Among them, a cylindrical rod 2 108 is fixed to the end of the correcting rod 204 away from the support plate 101, and a mounting plate 2 106 is provided below the correcting rod 204. Two ear plates 2 107 are fixed on the mounting plate 2 106. The cylindrical rod 2 108 passes through the ear plate 2 107 and is rotatably connected to the ear plate 2 107. Mounting holes 109 are provided in both the mounting plate 2 106 and the mounting plate 1 102.

[0029] When using, Figure 7 As shown, a plurality of embedded grooves 301 are opened on the side wall 300 of the subway tunnel. Then, the mounting plate 102 and the mounting plate 2 106 are placed in the corresponding embedded grooves 301 and fixed to the side wall 300 of the subway tunnel with bolts. Then, concrete is filled in the embedded grooves 301 to firmly fix the mounting plate 102, the mounting plate 2 106 and the side wall 300 of the subway tunnel together, thereby preventing the mounting plate 102 and the mounting plate 2 106 from being affected by the vibration of the subway.

[0030] In addition, two rectangular grooves 205 are provided on the support plate 101, and a rectangular block 206 is slidably connected in the rectangular groove 1 205. A baffle 1 207 is fixed on the top of the rectangular block 206, and the length and width of the baffle 1 207 are both larger than the length and width of the rectangular groove 1 205. A rectangular groove 208 is provided in the rectangular block 206, and a rectangular groove 3 209 is provided in the rectangular frame 201, and the length and width of the rectangular groove 208 are equal to the length and width of the rectangular groove 3 209.

[0031] In addition, the fixing part includes a positioning plate 210, which slides into the rectangular groove 208 and the rectangular groove 3 209. A baffle 211 is fixed to one end of the positioning plate 210, and the length and width of the baffle 211 are both larger than the length and width of the rectangular groove 3 209. An inner cavity 212 is provided in the end of the positioning plate 210 away from the baffle 211, and two protrusions 213 are slidingly connected in the inner cavity 212. The side of the protrusion 213 away from the baffle 211 is an inclined surface. A spring 214 is provided in the inner cavity 212, and the two ends of the spring 214 are respectively fixed to the two protrusions 213. Two travel grooves 216 are provided in the positioning plate 210, and the travel groove 216 is connected to the inner cavity 212. Two limit rods 215 are fixed on the protrusion 213, and the limit rods 215 slide into the corresponding travel grooves 216.

[0032] When in use, after the installation of mounting plate 102 and mounting plate 2 106 is completed, the support plate 101 and the correcting rod 204 are installed. At this time, it is necessary to assemble the support plate 101 and the correcting rod 204. Usually, the support plate 101 is rotated, and then the rectangular block 206 is passed through the rectangular groove 1 205, so that the baffle 1 207 and the top of the support plate 101 are abutted, and then the correcting rod 204 is rotated again, so that the top of the rectangular frame 201 and the bottom of the support plate 101 are fit. At this time, the rectangular block 206 is just located in the rectangular frame 201, and then the positioning plate 210 is inserted into the rectangular groove 3 209 and the rectangular groove 2 208. When the positioning plate 210 moves into the rectangular groove 3 209, the inclined surface of the protrusion 213 is squeezed and drives the protrusion 213 to move into the inner cavity 212, so that the spring 214 is compressed , then push the positioning plate 210 to move in the rectangular groove three 209 and the rectangular groove two 208. When the positioning plate 210 passes through the rectangular frame 201, the protrusion 213 is driven out of the inner cavity 212 under the rebound force of the spring 214. At this time, the protrusion 213 and the rectangular frame 201 are in contact, that is, the rectangular block 206 and the rectangular frame 201 are fixed, so that the correcting rod 204 and the support plate 101 are fixed. At this time, the support of the correcting rod 204 can correct the support plate 101, so that the support plate 101 remains in a horizontal state. When the bolt type is installed, it is necessary to use tools to rotate continuously when lifting the support plate 101, which takes a long time to install and is inefficient. This installation method is faster and more efficient. In addition, the bolt type fixation is easily affected by vibration and loosens, while this installation method will not be affected by vibration and has higher stability.
