[0023] The method of using this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figs. 1 to 4 As shown, a crane feeding transceiver device includes a base 1, a slider 2, a support frame 3, a U-shaped frame 4, a support platform 5, an insulator 6, and a connecting plate 7. The base 1 serves as a bottom support structure for mounting the support frame 3, and the bottom is provided with a slider 2. The support platform 5 is arranged on the U-shaped frame 4, and the support platform 5 is used to arrange the insulator 6. The support frame 3 and the U-shaped frame 4 are hinged to each other to realize the up and down movement of the support platform 5. The movement distance of the support platform 5 is limited by the connection between the connecting plate 7 and the U-shaped frame 4.

[0025] It also includes a first rod 8, a second rod 9, a tension spring 10, and a reset component 11; the support frame 3 is provided with the first rod 8, and the U-shaped frame 4 is provided with the second rod 9. The tension spring 10 is used to connect the U-shaped frame 4 and the first rod 8 to increase the bearing pressure of the support platform 5, and the reset component 11 is used to connect the first rod 8 and the second rod 9 to realize the movement buffer reset of the support platform 5.

[0026] The first rod 8 is arranged between the support frames 3, and the second rod 9 is arranged between the U-shaped frames 4. The first rod 8 and the second rod 9 are parallel to each other, and a reset member 11 perpendicular to the first rod 8 and the second rod 9 is provided between them; a tension spring 10 is provided between the U-shaped frame 4 and the first rod 8.

[0027] The support frame 3 includes a first bracket 31 and a second bracket 32, with one end of each of the first brackets 31 and the second bracket 32 ​​respectively disposed on both sides of the middle part of the base 1;

[0028] The U-shaped frame 4 includes a first frame 41 and a second frame 42. The bottom edges of the first frame 41 and the second frame 42 are respectively provided with a plurality of round holes 12. The first frame 41 is arranged between the first supports 31 and the second frame 42 is arranged between the second supports 32.

[0029] The connecting plate 7 includes a first connecting plate 71 and a second connecting plate 72. One end of the first connecting plate 71 is connected to one side end of the first frame 41, and the other end is connected to the middle of one side of the second frame 42. One end of the second connecting plate 72 is connected to the middle of the other side of the first frame 41, and the other end is connected to the other side end of the second frame 42.

[0030] It should be noted that the first connecting plate 71 and the second connecting plate 72 are connected to the first frame 41 and the second frame 42, which limits the rotation angle of the U-shaped frame 4, thereby limiting the distance that the support platform 5 can move downward after being subjected to pressure.

[0031] The tension springs 10 between the plurality of first supports 31 are spaced equally, and the tension springs 10 between the plurality of second supports 32 are spaced equally.

[0032] This is to ensure that the tension springs 10 are evenly stressed when the support platform 5 is under pressure, so that the support platform 5 can withstand greater pressure.

[0033] The reset component 11 includes a first collar 111, a cylinder 112, a compression spring 113, a push rod 114, and a second collar 115. The cylinder 112 is provided on the outer circumference of the first collar 111, and the compression spring 113 is provided inside the cylinder 112. The first collar 111 is sleeved on the outer surface of the second rod 9. The push rod 114 is provided on the outer circumference of the second collar 115. The push rod 114 slides inside the cylinder 112, and the second collar 115 is sleeved on the outer surface of the first rod 8.

[0034] It should be noted that, depending on the pressure borne by the support platform 5, one or more reset pieces 11 can be added between the first rod 8 and the second rod 9 to ensure that the support platform 5 can withstand greater pressure and can quickly reset. Furthermore, when installing multiple reset pieces 11, it is necessary to ensure that the distance between each reset piece 11 is equal to ensure uniform force distribution, and the reset pieces 11 on both sides are arranged symmetrically.

[0035] Each of the multiple tension springs 10 has a hook 101 at both ends. One end of the tension spring 10 hook 101 passes through the circular hole 12, and the other end of the hook 101 contacts the first rod 8.

[0036] The hook 101 is used to connect the U-shaped frame 4 and the first rod 8. The use of the hook 101 facilitates the replacement of the tension spring 10 and also improves the installation efficiency, ensuring the quick installation of the tension spring 10.

[0037] Working process: When the insulator 6 is subjected to downward pressure, the support platform 5 will move downward, causing the first frame 41 and the second frame 42 on both sides of the support platform 5 to rotate downward. The included angle between the first frame 31 and the second frame 32 will widen. At the same time, the bottom edge of the first frame 41 and the second frame 42 will drive the tension spring 10, causing the tension spring 10 to be stretched. Furthermore, the first rod 8 on the first frame 41 and the second frame 42 will move downward as they rotate, causing the push rod 114 on the reset member 11 to move downward. The push rod 114 moves downward inside the cylinder 112, pushing the compression spring 113, causing the compression spring 113 to be compressed. This increases the bearing pressure of the support platform 5, ensuring that the slider 2 and the sliding contact line always run in close contact. When the pressure on the insulator 6 decreases, the compression spring 113 inside the reset member 11 and the elastic potential energy of the tension spring 10 will work together to reset the insulator 6.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
