Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit electronic signal boards, in particular to a lifting type rail transit electronic signal board. Background Art

[0002] Rail transit electronic signal boards are important equipment used to display various information in urban rail transit. They are designed to ensure the safe and punctual operation of trains and provide necessary information to passengers.

[0003] Existing rail transit electronic signal boards are usually fixed in position and do not have the function of lifting. When the electronic signal board is too high, it is difficult for passengers to notice it, which reduces the penetration effect and easily causes passengers to go to the wrong platform. When the electronic signal board is too low, it will block the solid line. At the same time, when passengers carry long items, they are likely to collide with the electronic signal board and cause damage. Therefore, we proposed a lifting rail transit electronic signal board. Utility Model Content

[0004] The purpose of the present utility model is to provide a lifting type rail transit electronic signal board. By setting a lifting component, specifically, starting a motor to drive a rotating rod to rotate forward or reverse, when the rotating rod rotates forward, the reel will reel in the traction rope, so that the height of the electronic signal board is increased, and when the rotating rod is reversed, the reel will unwind the traction rope, and the electronic signal board will be lowered. By adjusting the height of the electronic signal board, passengers can better observe the information on the electronic signal board, avoid collisions of the electronic signal board, reduce economic losses, and increase the service life of the electronic signal board. It solves the problem that the existing rail transit electronic signal board is usually fixed in position and does not have the lifting function. When the electronic signal board is too high, it is difficult for passengers to notice it, which reduces the penetration effect and easily causes passengers to go to the wrong platform. When the electronic signal board is too low, it will block the line of sight.

The side of the fixing block 31 close to the mounting seat 14 is fixedly connected to the surface of the mounting seat 14. By setting the lifting component 11, specifically starting the motor 115 to drive the rotating rod 114 to rotate forward or reverse, when the rotating rod 114 rotates forward, the reel 41 will reel the traction rope 112, thereby raising the height of the electronic sign 12.

By adjusting the height of the electronic sign 12, passengers can better observe the information on the electronic sign 12, avoid collisions with the electronic sign 12, reduce economic losses, and increase the service life of the electronic sign 12.

[0027] The back of the electronic signal board 12 is fixedly connected to a fixing plate 121, and an insert block 122 is fixedly connected to the center of the back of the fixing plate 121.

Grooves are provided at the top and bottom of the support rod 123, and an elastic plate 231 is fixedly connected to the inner wall of the groove. The support rod 123 is plugged into the mounting seat 14, and the back of the fixing plate 121 is plugged into the mounting seat 14. By setting the support rod 123, specifically when the electronic signal board 12 is installed, the electronic signal board 12 is plugged into the mounting seat 14 through the insert block 122 and the support rod 123 on the fixing plate 121. When the elastic plate 231 on the support rod 123 moves into the mounting seat 14, it will be reset under the action of elasticity, thereby playing a limiting role. The support rod 123 will be used to support the electronic signal board 12, which is convenient for the subsequent operation of the staff. There is no need to continuously support the electronic signal board 12, reducing the labor of the staff.

[0029] Extrusion rods 244 are provided at the top and bottom of the moving block 242. The parts connected to the two extrusion rods 244 are the same. The left and right sides of the bottom of the upper extrusion rod 244 are connected to connecting blocks 245 through pin shafts.

[0030] The bottom of the connecting block 245 is fixedly connected to the top of the moving block 242, the back of the extrusion rod 244 contacts the limiting frame 246, and the bottom of the limiting frame 246 is fixedly connected to the top of the moving block 242. After the extrusion rod 244 contacts the inner wall of the mounting seat 14, the extrusion rod 244 and the limiting frame 246 cooperate with each other to tightly adhere to the inner wall of the mounting seat 14.

[0031] The back of the fixing plate 121 contacts the front of the mounting seat 14, the cover 13 is inserted into the back of the mounting seat 14, the outer surface of the moving block 242 contacts the inner wall of the fixing frame 124, the front of the extrusion rod 244 contacts the inner wall of the mounting seat 14, and a circular hole is opened in the center of the cover 13, which is adapted to the turning handle 243. The cover 13 is put on the back of the mounting seat 14 to play a role of shielding and dustproofing.

[0032] A specific application of this embodiment is:

[0033] When the electronic signal board 12 needs to be installed, the electronic signal board 12 is first plugged into the mounting seat 14 through the plug block 122 and the support rod 123 on the fixing plate 121. When the elastic plate 231 on the support rod 123 contacts the mounting seat 14, it will be squeezed, so that the elastic plate 231 enters the support rod 123, so that the support rod 123 can smoothly enter the mounting seat 14. When the elastic plate 231 moves into the mounting seat 14, it will be reset under the action of elasticity, thereby playing a limiting role. The support rod 123 will be used to support the electronic signal board 12, which is convenient for the subsequent operation of the staff. There is no need to continuously support the electronic signal board 12, which reduces the labor of the staff. At this time, the plug block 122 is also plugged into the mounting seat 14, and then the two squeezes are pressed together. The pressing rod 244 is stretched open, and the turning handle 243 is turned clockwise to drive the threaded rod 241 to rotate. The moving block 242 on the threaded rod 241 will drive the extrusion rod 244 to move forward through the connecting block 245, so that the extrusion rod 244 contacts the inner wall of the mounting seat 14. The extrusion rod 244 is tightly attached to the inner wall of the mounting seat 14 through the cooperation with the limit frame 246, and the turning handle 243 is continuously turned to cause the threaded rod 241 to pull the plug block 122, so that the fixing plate 121 is tightly attached to the mounting seat 14, and the installation of the electronic signal board 12 is completed. Finally, the cover 13 is put on the back of the mounting seat 14 to play a role of shielding and dustproofing. The mounting plate 1 is then installed on the ceiling in the station with bolts. The electronic signal board 12 is used to display vehicle information. When the height of the electronic sign board 12 needs to be adjusted, the motor 115 is started to drive the rotating rod 114 forward or reverse. When the rotating rod 114 rotates forward, the reel 41 will reel in the traction rope 112, and the traction rope 112 drives the mounting base 14 to move upward, and the electronic sign board 12 will move along with it, thereby increasing the height of the electronic sign board 12. When the rotating rod 114 is reversed, the reel 41 will unwind the traction rope 112, and the electronic sign board 12 will descend. At the same time, when the electronic sign board 12 moves, the telescopic rod 113 will contract, which can limit the electronic sign board 12 and make the electronic sign board 12 move in a straight line. By adjusting the height of the electronic sign board 12, the passengers can better observe the electronic sign board 12. When the electronic sign board 12 needs to be disassembled for maintenance, the electronic sign board 12 is lowered to the lowest position to facilitate operation by the staff. First, the cover 13 is pulled out for disassembly, and then the handle 243 is turned counterclockwise to drive the threaded rod 241 to rotate. The moving block 242 will move backward, and the squeezing rod 244 will be away from the inner wall of the mounting seat 14, releasing the fixation of the electronic sign board 12. When the squeezing rod 244 moves to the rear of the insertion block 122, the squeezing rod 244 downward is lifted upward, and then the electronic sign board 12 is pulled forward to separate the support rod 123 from the mounting seat 14, and the disassembly is completed. The operation is simple and the efficiency is higher.
