[0018] The utility model will be further described below in conjunction with embodiment, but does not constitute any limit to the utility model, the limited times of modification that anyone does in the utility model claim scope is still in the utility model's claim scope.

[0019] Refer to Figures 1-4 ​This utility model discloses a segmented connection device for a sliding contact line, comprising an insulating plate 2 and a circuit breaker 3. The sliding contact line 1 has multiple cuts to divide it into several segments. In this embodiment, the sliding contact line 1 is I-shaped. Depending on site requirements, it can be segmented in 12-meter sections, with approximately 100mm cut off at each segment. Insulating plates 2 are provided on both sides of the cuts. The insulating plates 2 can be made of insulating alloy material to ensure the overall rigidity of the sliding contact line 1. The insulating plate 2 consists of a single-piece plate body 21 and a second plate body 22. The two ends of the first plate body 21 are fixed to the sliding contact line 1 on both sides of the cuts by locking members 4. The second plate body 22 extends into the sliding contact line 1, and the two insulating plates 2 form a connection structure consistent with the internal structure of the sliding contact line 1, thus forming the connecting plate in the middle of the I-shaped sliding contact line 1. Because the cut is insulated, a circuit breaker 3 is installed. Specifically, each section of the sliding contact line 1 is electrically connected to a circuit breaker 3, and the input terminal of the circuit breaker 3 is electrically connected to the power supply, thus realizing the electrical connection between two sections of the sliding contact line 1. When the overhead crane on a certain section of the sliding contact line 1 needs to be temporarily shut down for maintenance, or when a certain section of the sliding contact line 1 needs to be shut down for maintenance, only the power supply to the corresponding area needs to be stopped, which will not affect the normal operation of equipment in other areas, thus helping to maintain production stability.

[0020] In this embodiment, the locking component 4 includes a bolt 41 and a nut 42. The sliding contact line 1 has multiple through holes, and the plate 21 has threaded holes corresponding to the through holes. The bolt 41 is inserted into the through holes and threadedly connected to the threaded holes. The nut 42 is screwed onto the end of the bolt 41, thus achieving the fixed installation of the insulating plate 2.

[0021] In addition, to prevent the head of bolt 41 from protruding from the internal groove of the sliding contact line 1, a recessed groove is provided around the through hole in this embodiment to hide the head of bolt 41.

[0022] Considering the significant vibration received by the sliding contact line 1 when the crane moves, a retaining spring 43 is installed on the bolt 41 on one side of the nut 42 in this embodiment to position the nut 42 and prevent it from loosening and falling off.

[0023] The inner wall of the clamping spring 43 of the embodiment is provided with a plurality of obliquely arranged teeth 44. When the clamping spring 43 is tightly clamped on the bolt 41, the teeth 44 will be inserted into the thread groove of the bolt 41 to position the nut 42, thereby achieving the anti-loosening of the nut 42. The oblique direction of the teeth 44 is opposite to the loosening direction of the nut 42. When the nut 42 is loosened due to vibration, the loosening of the nut 42 will extrude or drive the clamping spring 43 to rotate, and the extrusion or rotation of the clamping spring 43 will make the teeth 44 more deeply inserted into the bolt 41, thereby further preventing the rotation of the nut 42 and greatly improving the anti-loosening effect. The heights of two adjacent teeth 44 are different, specifically, the height difference between the two adjacent teeth 44 is 3 / 4 of the thread groove depth of the bolt 41. Such arrangement makes the teeth 44 of the clamping spring 43 better adapt to the thread of the bolt 41, and makes the teeth 44 better clamped in the thread groove.

[0024] The above only describes the preferred embodiments of the present application, and it should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which will not affect the effect and practicality of the present application.
