Technical Field

[0001] The utility model relates to the technical field of railway turnout snow melting control, in particular to a railway turnout snow melting emergency control device based on wireless communication. Background Art

[0002] Snow melting on railway turnouts is primarily achieved through electric heating elements. When the temperature falls below a set point, the station's remote control terminal automatically or forcibly activates the heating elements, converting electrical energy into heat and transferring it to the required heating areas of the turnout, thereby melting snow and ice and ensuring flexible turnout operation. The turnout snow melting system, comprised of a control center, station control terminal, control cabinet, environmental monitoring device, and electric heating elements, offers intelligent control, energy conservation, environmental protection, safety, and reliability. In extreme weather, station attendants can activate an emergency operation button with a single click to quickly melt snow on the turnouts, ensuring normal train operation.

[0003] In the current existing technology, the heating strips installed on the side walls of the railway turnout tracks are connected to the electronic control components in the control box through the connection of wires. The electronic control components in the control box can be remotely controlled through wireless communication. When the electronic control components in the control box fail, the heating strips connected to them through wires will lose their heating effect on the rails, thereby causing the snow melting device to fail. The maintenance and replacement of the electronic control components in the control cabinet box requires a certain amount of time, which may affect the normal use of the railway turnout.

[0004] Therefore, in order to solve the above problems, a railway turnout snow melting emergency control device based on wireless communication is proposed. Utility Model Content

The electric control element in the control box housing 1 can perform precise heating control on the heating strip. When the electric control element in the control box housing 1 fails, the integration board 52 and the electric contact terminal 51 can be moved upward as a whole through the mutual cooperation between the various parts belonging to the control component 6, until the electric contact terminal 51 contacts the second contact head 42. At this time, the power transmission end is directly connected to the direct connector 3 on the transfer board 2, so that the direct connector 3 can directly power each second contact head 42 connected thereto, thereby allowing each heating strip to maintain the function of heating and melting snow. The insulating connection block 43 is installed in the middle of the branch board 4, and the first contact head 41 and the second contact head 42 are insulated, so that the process of the conductive wire 5 being electrically connected to the control box housing 1 and the direct connector 3 can not affect each other.

[0026] like Figure 3 and Figure 4As shown, the regulating assembly 6 includes a limiting guide rod 61, the axis of the limiting guide rod 61 is parallel to the center line of the branch plate 4, the limiting guide rod 61 is fixed to the outer wall of the control box housing 1 through a bracket, the outer wall of the limiting guide rod 61 is sleeved with a sliding sleeve 62, one side outer wall of the sliding sleeve 62 is fixedly connected to a spring guide rod 621, the outer wall of the spring guide rod 621 is sleeved with a linkage sleeve 63, the outer wall of the linkage sleeve 63 is fixed to the outer wall of one end of the integration plate 52 through the bracket, the sliding sleeve 62 sleeved on the outer wall of the limiting guide rod 61 can be fixed to the integration plate 52 through the linkage sleeve 63 sleeved on the outer wall of the spring guide rod 621, when it is necessary to change the contact state between the electric contact terminal 51, the first contact head 41 and the second contact head 42, it can be done by moving the relative height of the outer sliding sleeve 62 of the limiting guide rod 61;

The connection process can not affect each other. The sliding sleeve 62 mounted on the outer wall of the limiting guide rod 61 can be fixed to the integration plate 52 through the linkage sleeve 63 mounted on the outer wall of the spring guide rod 621.
