Description

Technical Field

[0001] The present invention relates to the field of traffic signal lamps, and more particularly to a traffic signal lamp which is convenient to maintain. Background Art

[0002] Traffic lights play a vital role in road traffic. Traffic lights can direct traffic in an orderly manner and ensure the safe passage of vehicles and pedestrians at intersections. Through the change of the color of the lamp head, traffic lights can clearly convey traffic information, allowing pedestrians or drivers to take corresponding actions according to the instructions of the signal light. This can not only improve road capacity and reduce traffic congestion, but also effectively reduce the incidence of traffic accidents.

[0003] For existing traffic lights, since the lamp heads are usually installed at high positions, maintenance such as replacing lamp heads, checking circuits, or cleaning and maintenance requires workers to perform high-altitude operations. Climbing operations require the use of special climbing equipment, such as ladders, scaffolding, or lifts. The use of these equipment itself increases the complexity of the operation and also poses a threat to the safety of the workers. During the climbing operation, improper operation or equipment failure may lead to serious accidents. In addition, during maintenance, the lamp heads usually need to be manually disassembled and installed, which is cumbersome and time-consuming, causing inconvenience to maintenance. Especially during busy urban traffic hours, the failure of traffic lights may cause traffic jams or even traffic accidents. Therefore, it is particularly important to complete the maintenance of traffic lights quickly and efficiently. However, the existing traffic light maintenance methods often cannot meet this demand due to the high-altitude operations and cumbersome disassembly and installation processes. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provide a traffic signal lamp which is convenient to maintain.

[0008] Furthermore, the second rotating rod has a threaded hole, the second sliding rail has a countersunk hole, and a fixing bolt that matches the threaded hole is installed in the countersunk hole.

[0009] Therefore, the second slide rail can be disassembled, making it convenient to take the signal lamp head out of the second slide rail for maintenance or replacement.

[0010] Furthermore, a support seat is provided at the bottom end of the vertical mounting groove, and a hinged component between the first rotating rod and the second rotating rod enables the first rotating rod and the second rotating rod to be in the same straight line at most.

[0011] Furthermore, when the lifting seat abuts against the supporting seat, the first rotating rod and the second rotating rod are in the same straight line.

[0012] Furthermore, the top of the signal lamp holder is connected to an abutment plate via a spring.

[0013] Furthermore, the traffic light can be in a use state, in which the first rotating rod and the fixed horizontal rod are parallel, the abutment plate of each traffic light head abuts the fixed horizontal rod, the connecting rope is in a stretched state, and the pull rope is in a taut state.

[0014] Thus, by stretching and tightening the connecting rope, and cooperating with the abutment plate of the signal lamp head abutting against the fixed horizontal rod, the fixed installation of the signal lamp head can be achieved.

[0015] In some embodiments, the connecting rope is an elastic connecting rope, and in the use state, the elastic connecting rope is in a stretched state.

[0016] Furthermore, the signal lamp head has three; the signal lamp head has three indicator lights, and each indicator light is provided with a sun visor.

[0031] The second rotating rod 6 has a threaded hole 6.3, and the second slide rail 6.2 has a countersunk hole 6.2.1. A fixing bolt that matches the threaded hole 6.3 is installed at the countersunk hole 6.2.1. The bottom end of the vertical mounting groove 1.1 has a support seat 1.2. The hinged component between the first rotating rod 4 and the second rotating rod 6 allows the first rotating rod 4 and the second rotating rod 6 to be in the same straight line at most; when the lifting seat 7 abuts against the support seat 1.2, the first rotating rod 4 and the second rotating rod 6 are in the same straight line.

And the signal lamp head is tightened by the pull rope and the connecting rope, and the abutment of the abutment plate, so that multiple signal lamp heads can be stably installed.

[0033] When the signal lamp head needs maintenance, the electric winding device releases the rope, and the lifting seat descends, so that the first rotating rod and the second rotating rod slowly rotate and descend until the signal lamp head is in a state of being ... Figure 5 As shown, the first rotating rod and the second rotating rod are in a straight line, and the signal lamp head at the end can be slid to the second rotating rod, and the signal lamp head can be taken out from the second slide rail by loosening the fixing bolt for maintenance or replacement. Therefore, the maintenance operation of the signal lamp does not require high-altitude work, so the maintenance is more convenient. After the maintenance is completed, the multiple signal lamp heads are all slid to the first rotating rod and the first and second rotating rods are restored to the use state, so that the use of the traffic light is realized.
