[0028] like Figures 1-6 As shown, this utility model discloses a vehicle power supply device, including multiple sliding lines 1 and a slider 2 for power supply to the vehicle. The sliding lines 1 are provided with mounting angle irons 3 for suspending and installing the sliding lines 1. The slider 2 is provided with a slider connecting plate 21 adapted to move with the sliding lines 1. The device also includes:
[0029] The reinforcing support mechanism 4 comprises a metal cross plate 41 arranged on the mounting angle iron 3, and two groups of insulating hangers 42 symmetrically arranged on both sides of the metal cross plate 41 and used for clamping and fixing a single slide wire 1;
[0030] The horizontal support mechanism 5 comprises an upper connecting plate 51 arranged on the upper part of one side of the slide wire 1 and used for horizontally connecting the adjacent slide wire 1.
[0031] The imbalance alarm assembly 6 is arranged in a slot on the metal cross plate 41 and / or the upper connecting plate 51 and used for monitoring the horizontal state of the slide wire 1.
[0032] In a specific implementation, the plurality of slide wires 1 for taking power by the trolley are sequentially fixed and installed in the steel plant by using the reinforcing support mechanism 4, and the horizontal support mechanism 5 is installed at the joint position of the two adjacent slide wires 1 in the plurality of slide wires 1, which is used for ensuring that the two adjacent connected slide wires 1 are in a horizontal state, and effectively avoiding the misalignment of the slide wire 1 joint in the horizontal and vertical directions.
[0033] The metal cross plate 41 is connected by using a bolt in the screw hole that is turned on the mounting angle iron 3, and the two groups of insulating hangers 42 that are symmetrically distributed are fixed and connected by using a bolt in the groove hole that is turned on both ends of the metal cross plate 41, wherein the metal cross plate 41 of the two groups of insulating hangers 42 connected on a single slide wire 1 can double the number of the insulating hangers 42, improve the carrying capacity of the insulating hangers 42 on the slide wire 1 at this position, and realize double insurance.
[0034] It should be noted that the imbalance alarm assembly 6 is arranged in a slot on the upper end surface of the metal cross plate 41 and / or the upper connecting plate 51, and the two imbalance alarm assemblies 6 arranged above have the same structure and working principle, which can monitor whether the slide wire 1 has a downward phenomenon and timely alarm to inform the staff, prevent damage caused by the downward inclination angle being too large, and improve the safety of work.
[0035] In an embodiment, the imbalance alarm assembly 6 comprises an insulating rolling groove 61, a first metal guide piece 62 and a second metal guide piece 63 arranged at both ends in the insulating rolling groove 61, a third metal guide piece 64 arranged on both sides of the insulating rolling groove 61 and not in contact with the first metal guide piece 62 and the second metal guide piece 63, and a metal ball 65 arranged in the insulating rolling groove 61 and rolling.
[0036] The metal ball 65 is used to roll to one end of the insulating rolling groove 61 when the sliding wire 1 is unbalanced, so as to make the first metal conductor 62 and the third metal conductor 64 or the second metal conductor 63 and the third metal conductor 64 conductive connection. In this way, by means of the first metal conductor 62 and the second metal conductor 63 embedded in the insulating rolling groove 61 and the insulating rolling groove 61 on the metal horizontal plate 41 and the upper connecting plate 51, and the third metal conductor 64 embedded in the remaining two ends of the insulating rolling groove 61,
[0037] When the sliding wire 1 fixed on the two groups of insulating hangers 42 falls, the metal ball 65 rolling in the insulating rolling groove 61 on the metal horizontal plate 41 moves to the side falling under the action of gravity, so that the metal conductor on the side falling and the third metal conductor 64 are in contact and conductive through the metal ball 65, thereby connecting the circuit on the side falling;
[0038] When the joint position of the two adjacent connected sliding wires 1 falls, the metal ball 65 moves to the side falling on the insulating rolling groove 61 on the upper connecting plate 51 under the action of gravity, and then the metal conductor on the side falling and the third metal conductor 64 are in contact and conductive through the metal ball 65, thereby connecting the circuit on the side falling.

In this way, by means of the recesses polished on the opposite end faces of the joints on both sides of the sliding wire 1, the deviation can be compensated, and the impact force when the sliding block 2 passes can be effectively reduced.
[0042] In an embodiment, the slide connecting plate 21 is provided with large chamfering parts 211 at both ends, and the side of the large chamfering parts 211 is provided with side chamfering parts 212. Through the large chamfering parts 211 at both ends of the slide connecting plate 21, and the total length of the large chamfering parts 211 at both ends accounts for 1 / 3 of the total length of the slide connecting plate 21, the micro deviation of the joint can be compensated by the large chamfering of the slide connecting plate 21, and the impact force of the slide block 2 is reduced;
[0043] The side chamfering parts 212 are further polished and processed at the front and back of the side of the large chamfering parts 211 at both ends, and the deviation compensation is further realized.
