DETAILED DESCRIPTION

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 - Figure 4 As shown, the railway crossing signal comprises a counterweight seat 1, a lamp pole 2 with an internal hollow interior is fixedly mounted on the top of the counterweight seat 1, a motor 3 is fixedly mounted in the inner cavity of the bottom end of the lamp pole 2, a screw rod 4 is fixedly connected to the output end of the motor 3 and extends upward along the inner cavity of the lamp pole 2 to the top end of the lamp pole 2, a limit head with a cylindrical structure is fixedly connected to the top end of the screw rod 4, the diameter of the limit head is larger than the diameter of the screw rod 4, a lifting plate 5 is sleeved on the screw rod 4, a threaded hole adapted to the size of the screw rod 4 is opened in the center of the lifting plate 5, the lifting plate 5 is screwed to the screw rod 4 through the threaded hole, and when the motor 3 is started to drive the screw rod 4 to rotate, the lifting plate 5 can be pushed up and down along the inner cavity of the lamp pole 2 under the action of the thread;

[0021] A through hole 6 is provided on one side of the lamp pole 2, and the lifting plate 5 extends toward the outside of the through hole 6 near the through hole 6 to form a connecting portion that can slide up and down along the through hole 6. The inner cavity width of the through hole 6 is adapted to the width of the connecting portion. A signal indicator device is installed at one end of the connecting portion outside the through hole 6. The height of the bottom end of the through hole 6 from the ground is not higher than 150 cm. When the lifting plate 5 moves up and down along the inner cavity of the lamp pole 2, it can drive the connecting portion to move up and down synchronously along the through hole 6. The height of the bottom end of the through hole 6 from the ground is set low, so that the lifting plate 5 can drive the connecting portion to descend along the through hole 6 to a position close to the height of a human body, which is convenient for staff to inspect and repair the signal indicator device installed on the connecting portion.

[0022] The signal indicator device includes a lamp holder 7 mounted on the connecting portion. Two signal lamps 8 are electrically connected to the side of the lamp holder 7 facing away from the lamp pole 2. The two signal lamps 8 generate light of different colors. The lamp holder 7 and the signal lamp 8 are mounted on the connecting portion so that the movement of the connecting portion can drive the lamp holder 7 and the signal lamp 8 to move. The height of the signal lamp 8 can be adjusted to set the signal lamp 8 to generate light of different colors to indicate different signals.

[0023] A power supply structure for supplying power to the signal indicator device is provided in the sealed box 9. The power supply structure includes a busbar rail 10 vertically mounted on the inner wall of the sealed box 9. The busbar rail 10 is electrically connected to the power distribution control cabinet 12. The power supply structure also includes a brush 11 fixedly mounted on the side of the lifting plate 5 away from the connection portion. The brush 11 is electrically connected to the busbar rail 10 and can slide upward in the height direction of the busbar rail 10. The lamp holder 7 is electrically connected to the brush 11 through a wire for controlling and powering the signal lamp 8.

[0024] It should be noted that the railway crossing signal, when used, the counterweight seat 1 is placed beside the railway crossing, and the signal lamp 8 installed on the lamp holder 7 generates light of different colors to provide command signals for the train. When the signal lamp 8 is damaged due to long-term use and needs to be repaired or replaced, the motor 3 can be started through the power distribution control cabinet 12 to drive the lead screw 4 to rotate, and the lifting plate 5 is pushed down along the inner cavity of the lamp pole 2 by the screw thread action. Since the lifting plate 5 extends towards the outside of the through hole 6 on one side close to the through hole 6 to form a connecting part that can slide up and down along the through hole 6, and the signal lamp 8 is installed on the end of the connecting part outside the through hole 6 through the lamp holder 7, when the lifting plate 5 moves down, the signal lamp 8 can be driven by the connecting part to move down to a lower position at the same time, so that the maintenance and replacement work of the signal lamp 8 can be completed directly on the ground by the staff. Not only is the operation convenient, but also the safety during the maintenance of the signal lamp 8 is greatly improved. When the maintenance is completed, the user can start the motor 3 to drive the lead screw 4 to rotate in the opposite direction, and the lifting plate 5 is pushed to the top end of the lamp pole 2 through the screw thread, thereby driving the signal lamp 8 installed on the connecting part to move to a high place again.

[0025] Example 2

[0026] Further improvements are made on the basis of example 1, as shown in Figure 1 and Figure 2 The lamp pole 2 on both sides of the through hole 6 is fixedly connected with a side sealing plate 13, the two side sealing plates 13 are symmetrically distributed, and a PVC corrugated plate 14 is slidably connected between the two side sealing plates 13. The bottom sides of the PVC corrugated plate 14 are connected with the bottom of the side sealing plate 13, and the top end of the PVC corrugated plate 14 is fixed with the lower surface of the connecting part.

[0027] The side sealing plate 13 and the PVC corrugated plate 14 are provided to seal the through hole 6 when the signal lamp 8 is in the working state, so as to avoid rainwater from entering the lamp pole 2 to cause the motor 3 to be damaged due to water immersion. At the same time, since the top end of the PVC corrugated plate 14 is fixed with the lower surface of the connecting part, when the connecting part slides down, it can push the PVC corrugated plate 14 to slide down along the side sealing plate 13. When the bottom end of the PVC corrugated plate 14 touches the ground, since the PVC corrugated plate 14 has foldable properties, the PVC corrugated plate 14 can be folded to the lower end, which does not affect the connecting part to drive the signal lamp 8 to slide down to a lower position for maintenance work.

[0028] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
