AI Technical Summary
The trolley power supply cable of the existing trolley furnace is easily broken by falling objects when entering or out of the furnace, and the operator is easily tripped by the cable when walking, which poses a safety hazard.
A trolley power cable trench automatic opening and closing cover mechanism is designed, including a bow frame connected to the trolley and a limit cover plate surrounded by the power cable trench. It is connected to the trolley through the top fixed bracket of the arc frame of the bow frame. The limit cover plate is composed of a movable cover plate and a fixed cover plate. The movable cover plate is connected to the fixed cover plate through the limit hinge. When the arch frame is located outside the power cable trench, the movable cover plate covers the cable trench mouth; when the arch frame enters the cable trench, the movable cover plate automatically falls and covers the cable trench to realize the automatic closing function.
Through the automatic opening and closing cover mechanism, the cable is always in the power cable trench when the trolley enters or drives out of the oven, and is protected by the limit cover, preventing falling objects from hurting the cable and operators from tripping over the cable, which significantly improves safety.

[0008] Preferably, the maximum opening angle of the limit hinge 4 is 40°-60°.
[0009] Preferably, the arc frame 12 of the arch frame 1 is arranged directly above the straight frame 11 .
[0010] Preferably, the limiting cover plate 2 is made of carbon steel.
[0011] Preferably, the fixing bracket 3 is made of carbon steel.
[0012] Preferably, the fixing bracket 3 is connected to the bow-shaped bracket 1 by welding.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] When the trolley enters or drives out of the furnace, the arc frame of the bow frame pushes open the movable cover plate of the limit cover plate, so that the cable connected to the driving motor in the trolley can enter the power cable trench; when the trolley leaves the limit cover plate, the arc frame leaves the movable cover plate, and the movable cover plate automatically falls down by its own weight to cover the power cable trench, thereby realizing the automatic closing function of the utility model. When the trolley enters or drives out of the furnace, the cable of the trolley is always in the power cable trench and is protected by the limit cover plate to prevent falling objects from damaging the cable and prevent workers from tripping over the cable.

[0018] A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings to clearly and completely describe the technical solution in a preferred embodiment of the present invention.
[0019] like Figure 1 As shown, the automatic opening and closing cover mechanism of the trolley power cable trench comprises a bow frame 1 fixedly connected to the trolley 100 and a limiting cover plate 2 arranged around the periphery of the power cable trench 101, the bow frame 1 is composed of a straight frame 11 and an arc frame 12, a fixed bracket 3 is provided on the top of the arc frame 12, and the fixed bracket 3 is used to be fixedly connected to the trolley 100; the limiting cover plate 2 comprises a movable cover plate 21 and a fixed cover plate 22, the movable cover plate 21 and the fixed cover plate 22 are rotatably connected by a limiting hinge 4, and the fixed cover plate 22 is used to be fixedly connected to the ground outside the power cable trench 101; when the bow frame 1 is located outside the power cable trench 101, the movable cover plate 21 covers the trench mouth of the power cable trench 101; when the bow frame 1 is located inside the power cable trench 101, the straight frame 11 of the bow frame 1 is lower than the trench mouth of the power cable trench 101, and the movable cover plate 21 of the limiting cover plate 2 covers the upper edge of the arc frame 12.
[0020] Through the above design, when the trolley 100 enters or drives out of the furnace, the arc frame 12 of the bow frame 1 pushes open the movable cover plate 21 of the limiting cover plate 2, so that the cable 103 connected to the driving motor 102 in the trolley 100 can enter the power cable trench 101; when the trolley 100 leaves the limiting cover plate 2, the arc frame 12 leaves the movable cover plate 21, and the movable cover plate 21 automatically falls down by its own weight to cover the power cable trench 101, thereby realizing the automatic closing function of the utility model. When the trolley 100 enters or drives out of the furnace, the cable 103 of the trolley 100 is always in the power cable trench 101, and is protected by the limiting cover plate to prevent falling objects from damaging the cable 103 and prevent workers from being tripped by the cable 103.
[0021] Specifically, the maximum opening angle of the limit hinge 4 is 40°-60°.
[0022] Through the above design, the maximum opening angle of the limit hinge 4 of the utility model is between 40 degrees and 60 degrees, not exceeding 90 degrees, so as to make the movable cover plate 21 reposition by itself and prevent the angle between the movable cover plate 21 and the fixed cover plate 22 from being too large, so that the cable groove 101 cannot be re-covered by its own weight.
[0023] Specifically, the arc frame 12 of the arch frame 1 is arranged directly above the straight frame 11 .
[0024] Through the above design, the utility model forms a semi-olive-shaped structure with a wide middle and narrow ends, and when the trolley 100 enters or drives out of the furnace, the narrow parts at both ends facilitate the arch frame 1 to enter the power cable trench 101, so as to lift the movable cover plate 21.
[0025] Specifically, the bow-shaped frame 1 is made of carbon steel, the limiting cover plate 2 is made of carbon steel, the fixing bracket 3 is made of carbon steel, and the fixing bracket 3 is connected to the bow-shaped frame 1 by welding.
[0026] The utility model has a higher structural strength and is not easy to deform through the above design.
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
