Detailed Embodiments

[0019] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made with reference to the accompanying drawings.

Please refer to Figures 1 - 8 : including; main shaft 1; support wheel 2; support disc 3, which is arranged at both ends of the main shaft 1 and has different sizes. The support wheel 2 is arranged at the lower end of the support disc 3; cable rack 4, and both ends of the cable rack 4 are rotatably connected to the support disc 3; brake pad 5, and the brake pad 5 contacts the support disc 3 to generate frictional force to form braking force; There are a pair of elastic beams 6. The support disk 3 is located in the middle of the elastic beams 6. The elastic potential energy drives the brake pads 5 to separate from the support disk 3. A load-bearing member 7 for connecting the brake pads 5 and the elastic beams 6. A driving member 8 pulls the elastic beams 6 closer to each other, indirectly driving the brake pads 5 to press against the support disk 3.

[0021] Specifically in actual applications, this application is a braking mechanism in a contracting machine. Through the action of the support wheel 2, the support disk 3 is in a stable state. Before use, the cable reel is fixed on the cable rack 4, and then the cable is manually withdrawn. Through the external main drive motor and the main reducer, the support disk 3 and the cable rack 4 can be driven to rotate integrally for contracting operations. When braking is required, control the driving member 8 to work. The driving member 8 drives the upper ends of the two elastic beams 6 to approach each other. The elastic beams 6 drive the brake pads 5 to approach the support disk 3 through the load-bearing member 7. The brake pads 5 contact the support disk 3. Through the continuous pressure of the driving member 8, the pressure between the brake pads 5 and the support disk 3 gradually increases, and finally the effect of rapid braking is achieved.

[0022] Refer to Figure 1 、 Figure 5 and Figure 6 , the elastic beam 6 is divided into channel steel one 61, channel steel two 62 and square steel 63. Channel steel one 61 and channel steel two 62 are arranged back to back, and the square steel 63 is arranged at intervals between channel steel one 61 and channel steel two 62. The wall thickness of the square steel 63 gradually becomes thinner from bottom to top. The lower end of the elastic beam 6 is fixedly connected to the foundation pit.

[0023] Specifically in actual applications, through the setting of channel steel one 61 and channel steel two 62, the structural strength of the overall elastic beam 6 can be enhanced. Through the interval setting of the square steel 63, while playing the role of connecting channel steel one 61 and channel steel two 62, the elastic beam 6 has better toughness. Through the setting that the wall thickness of the square steel 63 gradually becomes thinner from bottom to top, the elasticity of the upper end of the elastic beam 6 is increased.

[0024] Embodiment 1 of the driving member 8, refer to Figure 1 and Figure 2 , the driving member 8 includes a lifting ring 81 fixedly installed at the upper end of the elastic beam 6.

A connecting rod 83 is installed between one end of the triangular plate 82 and the lifting ring 81, and a first hydraulic cylinder 84 is installed between the other end of the triangular plate 82 and the elastic beam 6.

[0025] Specifically in actual applications, when braking is required, control the first hydraulic cylinder 84 to extend. The first hydraulic cylinder 84 drives one end of the triangular plate 82 to rotate counterclockwise. The other end of the triangular plate 82 pulls the connecting rod 83, making the upper ends of the elastic beams 6 approach each other. The elastic beams 6 indirectly drive the brake pads 5 to brake the support disk 3.

[0027] Specifically in actual applications, when braking is required, control the reduction motor 86 to rotate forward. The reduction motor 86 drives the rotating rod 87 to rotate. The rotating rod 87 and the internally threaded tube 85 are in a state of screwing in. By rotating the rotating rod 87, the upper ends of the two elastic beams 6 are tightened, indirectly achieving the purpose of braking. The elastic beam 6 can be released by reversing the reduction motor 86.

[0028] Refer to Figure 1 and Figure 8 , a hole 31 is opened on the side wall of the support disk 3, a hole 32 is opened on the cable rack 4, the position of the hole 32 corresponds to that of the hole 31, and a pin shaft 33 is provided in the hole 31 and the hole 32; a hinge plate 64 is installed on the side wall of the elastic beam 6.

[0029] Specifically in actual applications, both ends of the cable rack 4 are in a rotatable state with the support wheel 2. Insert the pin shaft 33 into the hole 31 and the hole 32 to make the cable rack 4 and the support disk 3 in a relatively fixed state, avoiding the cable rack 4 rotating freely during operation.

[0030] Embodiment 1 of the load-bearing component 7, this embodiment has a stable structure but a relatively high cost.

[0031] Specifically in actual applications, the hinge plate 64 is fixedly connected to the elastic beam 6. The arc-shaped box body 71 is installed on the hinge plate 64 and is in a freely rotatable state. The elastic beam 6 drives the arc-shaped box body 71 and the brake pad 5 to tightly press against the surface of the support disk 3, achieving the braking effect. Through the elastic force of the elastic beam 6 itself, there is a gap between the support disk 3 and the brake pad 5.

[0033] Specifically in actual application, when the support disc 3 rotates, it drives the wind plate 714 to revolve, and the wind plate 714 stirs the air flow around the brake pad 5 to flow rapidly. By setting the shape of the wind plate 714, the air flow can be increased; frequent braking causes the temperature of the brake pad 5 to be relatively high. The high-temperature air flow diffuses into the arc-shaped box body 71 through the heat dissipation holes 711, and the cold air flow enters the arc-shaped box body 71 from the ventilation holes 712 at the lower end and both sides, and is discharged from the ventilation holes 712 at the upper end of the arc-shaped box body 71. At the same time, the heat of the heat dissipation holes 711 is taken away, achieving the effect of air cooling.

[0037] Specifically in actual application, as the brake pad 5 wears out, the thickness of the brake pad 5 gradually becomes thinner. When it is thin to the critical value, the elastic piece 641 contacts the sound-generating protrusion 642. When the support disc 3 rotates again, a regular high-frequency sound will be emitted to remind the staff to perform the replacement operation.
