DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides technical schemes:

[0025] A kind of automatic electric connection device for iron car hitching of accurate positioning, including two installation frames 1, the inside of installation frame 1 is bolted with guide assembly 2, and the opposite side of two guide assemblies 2 is provided with butt joint plate 3, the top of butt joint plate 3 is bolted with electric connection assembly 4, the rear side of front butt joint plate 3 is bolted with positioning pin 5, the inside of rear butt joint plate 3 is provided with positioning sleeve 6, and positioning pin 5 and positioning sleeve 6 are used in cooperation;

[0026] Electric connection assembly 4 includes mounting plate 41, and mounting plate 41 is bolted on the top of butt joint plate 3, and the inside of mounting plate 41 is rotatably connected with lead screw 42, the surface of lead screw 42 is threadedly connected with screw block 43, and the side of screw block 43 extends to the outside of mounting plate 41 and is bolted with electric connection slide plate 44, a plurality of contact sheets 45 are arranged on the side, away from mounting plate 41, of electric connection slide plate 44, and a plurality of contact springs 46 are arranged between the side, opposite to electric connection slide plate 44, of contact sheet 45.

[0027] In the embodiment, the power connection assembly 4 is used to adjust the position of the power connection slide plate 44 on the mounting plate 41 through the threaded connection between the lead screw 42 and the screw block 43. The position of the power connection slide plate 44 can be conveniently adjusted by rotating the lead screw 42 to adapt to different power connection positions. The contact spring 46 between the contact piece 45 and the power connection slide plate 44 can ensure that the contact piece 45 always maintains good elastic pressure during contact. Even in the case of slight vibration of the molten iron car or uneven surface of the power supply device, stable conductive connection can be ensured, reducing the occurrence of poor contact and improving the reliability and stability of power transmission, ensuring the smooth progress of the related work of the molten iron car.

[0028] Specifically, as shown in Figure 3 The guide assembly 2 includes a ball head seat 21 that is bolted to the inside of the mounting frame 1. One side of the ball head seat 21 is welded with a guide rod 22, and one side of the guide rod 22 extends into the inside of the positioning sleeve 6.

[0029] Specifically, as shown in Figure 3 The mounting frame 1 is bolted with a fixed sleeve 23 near one side of the butt joint plate 3, and the inside of the fixed sleeve 23 is provided with a connecting sleeve 24 that is sleeved on the surface of the guide rod 22.

[0030] Specifically, as shown in Figure 3 The opposite sides of the fixed sleeve 23 and the connecting sleeve 24 are provided with a rubber sleeve 25, and the inside of the rubber sleeve 25 is annularly provided with a cavity.

[0031] In the embodiment, by setting the guide assembly 2, the positioning pin 5 on the front side butt joint plate 3 gradually approaches the positioning sleeve 6 of the rear side butt joint plate 3. During the approach, the movement path of the positioning pin 5 is constrained by the positioning sleeve 6, and the guide rod 22 can adapt to the posture of the positioning pin 5 through the ball head seat 21. Meanwhile, the connecting sleeve 24 can be deflected in the fixed sleeve 23 by using the rubber sleeve 25, and cooperate with the ball head seat 21 to adapt to the precise positioning and power connection work in various environments.

[0032] Specifically, as shown in Figure 5 The number of contact pieces 45 is several, and they are equidistantly distributed on one side near the power connection slide plate 44.

[0033] In the embodiment, by setting the number of contact pieces 45 to several and equidistantly distributing them on one side near the power connection slide plate 44, the elastic deformation of the contact spring 46 during contact can absorb part of the vibration and impact force, further reducing the unstable power connection caused by external interference.

[0034] Specifically, as shown in Figure 1As shown, a connecting plate 7 is provided on the side of the fixed sleeve 23 near the docking plate 3, and a buffer spring 8 is sleeved on the surface of the guide rod 22, and the buffer spring 8 is connected to the docking plate 3 and the connecting plate 7 respectively on the side near the docking plate 3.

[0035] In this embodiment, by setting the connecting plate 7 and the buffer spring 8, the force can be buffered during the docking process, thus ensuring the stability of the connection process.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, the positioning sleeve 6 is generally tapered and is slidably fitted onto the surface of the guide rod 22, and the rear side of the positioning pin 5 is tapered.

[0037] In this embodiment: With the above settings, when the power is connected, the positioning pin 5 first contacts the conical inlet of the positioning sleeve 6. Due to the guiding effect of the conical structure, the positioning pin 5 is gradually inserted along the conical inner wall of the positioning sleeve 6 under the constraint of the guide rod 22. During the insertion process, if there is a positional deviation, the conical surface will generate a lateral force, causing the positioning pin 5 and the guide rod 22 to automatically adjust their positions and finally accurately insert into the bottom of the positioning sleeve 6, thereby achieving the effect of accurate positioning during the power connection process.

[0038] Working principle: When using the power connection device, the mounting bracket 1 can be installed on the frame of the molten iron car, ensuring that the installation is in a position unaffected by changes in frame height due to load, frame swaying during ladle lifting, or other factors. When the molten iron car is attached, it will approach the positioning sleeve 6 via the positioning pin 5. When the positioning pin 5 contacts the conical inlet of the positioning sleeve 6, the conical structure begins to perform its guiding and self-correcting functions, allowing the positioning pin 5 to gradually insert along the conical inner wall of the positioning sleeve 6. Furthermore, when the molten iron car has a certain positional deviation or swaying, the lateral force generated by the conical surface will also cause the guide rod 22 to drive the connecting sleeve 24 to automatically adjust its angle and position within the fixed sleeve 23. Finally, the positioning pin 5 is accurately inserted into the bottom of the positioning sleeve 6 to achieve precise docking. At the same time as the positioning pin 5 docks with the positioning sleeve 6, the lead screw 42 is driven to rotate by the external drive device. The threaded engagement between the lead screw 42 and the screw block 43 causes the contact plate 44 to be displaced to a certain extent, so that the two contact pieces 45 can be precisely positioned. As the positioning pin 5 is positioned, the front and rear contact pieces 45 can make tight contact. Due to the action of the contact spring 46 between the contact piece 45 and the contact plate 44, the contact piece 45 can maintain a certain elastic pressure, forming multiple stable conductive contact points to complete the power connection.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
