Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more particularly to a cable processing braking mechanism and cable processing equipment. Background Art

[0002] The cable-laying machine is a large-scale cable manufacturing equipment. When working normally, its mass is large (fixing the reel and the cable-laying machine) and the speed is high (30 to 60 revolutions per minute). Due to the limitation of the back-end materials or different working conditions, it needs to be frequently stopped. The high-speed rotating cable-laying machine body needs to stop quickly, so it is necessary to design an efficient cable-laying machine braking mechanism. Summary of the Invention

[0003] In view of the above defects, the present invention provides a cable processing braking mechanism and a cable processing device to solve the above problems.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] Cable processing brake mechanism and cable processing equipment, including;

[0006] spindle;

[0007] Support wheels;

[0008] Support plates are provided at both ends of the main shaft and are of different sizes, and support wheels are provided at the lower end of the support plates;

[0009] A cable rack, both ends of which are rotatably connected to the support plate;

[0010] Brake pads, which contact the support disc to generate friction and form braking force;

[0011] There is a pair of elastic beams, with the support disc located in the middle of the elastic beams, and the elastic potential energy drives the brake pad to separate from the support disc;

[0012] A load-bearing component for connecting the brake pad and the elastic beam;

[0013] The driving component pulls the elastic beams closer to each other, indirectly driving the brake pads to fit tightly against the support disc.

[0014] Furthermore, the elastic beam is divided into channel steel 1, channel steel 2 and square steel. Channel steel 1 and channel steel 2 are arranged back to back, and the square steel is arranged between channel steel 1 and channel steel 2. The wall thickness of the square steel becomes thinner from bottom to top, and the lower end of the elastic beam is fixedly connected to the foundation pit.

[0015] The elasticity of the upper end of the elastic beam is increased by arranging that the thickness of the square steel gradually becomes thinner from bottom to top.

[0016] Furthermore, the driving component includes a lifting ring fixedly installed on the upper end of the elastic beam, a triangular plate is installed on the upper end of the elastic beam on the other side, the triangular plate is hinged to the elastic beam, a connecting rod is installed between one end of the triangular plate and the lifting ring, and a first hydraulic cylinder is installed between the other end of the triangular plate and the elastic beam.

[0017] Furthermore, the driving component includes an internal threaded tube fixedly mounted on the upper end of one elastic beam, a reduction motor is mounted on the upper end of the other elastic beam, a rotating rod is mounted on the rotating end of the reduction motor, and one end of the rotating rod is threadedly connected to the internal threaded tube.

[0018] Furthermore, a hole one is opened on the side wall of the support plate, and a hole two is opened on the cable rack. The position of the hole two corresponds to the position of the hole one, and pins are provided in the hole one and the hole two; a hinged plate is installed on the side wall of the elastic beam.

[0019] Furthermore, the bearing component includes an arc-shaped box body installed on the hinge plate, both sides of the arc-shaped box body are hinged to the hinge plate, one side of the arc-shaped box body is arc-shaped and fits with the support plate, and the brake pad is installed on the arc-shaped surface of the arc-shaped box body.

[0020] Furthermore, heat dissipation holes are provided on the parts of the arc-shaped box body that contact the brake pads, and air vents are provided at the upper and lower ends and both sides of the arc-shaped box body. Air flows into the arc-shaped box body from the air vents at the lower end and both sides, and are discharged from the air vents at the upper end of the arc-shaped box body, taking away the heat from the heat dissipation holes; wind plates are installed on the side walls of the support plate to fan the air flow.

[0021] When the support disc rotates, it drives the wind plate to revolve, and the wind plate fans the air flow around the brake pad to flow quickly. The shape of the wind plate can increase the air flow; frequent braking causes the brake pad temperature to be higher, and the high-temperature air flow diffuses into the curved box through the heat dissipation holes. The cold air flows into the curved box from the air vents at the bottom and both sides, and is discharged from the air vents at the upper end of the curved box.

[0023] Furthermore, an elastic sheet is installed on the hinged plate, and a sound-generating protrusion is provided on the annular surface of the support plate. The thinning of the brake plate can reduce the distance between the elastic sheet and the sound-generating protrusion. There are multiple groups of sound-generating protrusions, and each group of sound-generating protrusions is arranged at intervals, and each group of sound-generating protrusions is provided with multiple groups; a tension spring is installed between the upper end of the bearing component and the elastic beam, and the bearing component remains in a vertical state.

[0024] As the brake pad is consumed, its thickness gradually becomes thinner. When it becomes thin to a critical value, the elastic sheet contacts the sound-emitting protrusion. When the support disc rotates again, it will emit a regular high-frequency sound, reminding the staff to replace it.

[0025] Furthermore, the cable processing brake mechanism is installed on the cable processing equipment.

[0026] The beneficial effects of the present invention are as follows: the driving component drives the upper ends of the two elastic beams to approach each other, the elastic beams drive the brake pads to approach the support disc through the load-bearing component, the brake pads are in contact with the support disc, and through the continuous pressurization of the driving component, the pressure between the brake pads and the support disc gradually increases, ultimately achieving a rapid braking effect.

[0041] A cable rack 4, both ends of which are rotatably connected to the support plate 3;

[0042] Brake pad 5, brake pad 5 contacts support disc 3 to generate friction, thus forming braking force;

[0043] There is a pair of elastic beams 6, and the support plate 3 is located in the middle of the elastic beams 6. The elastic potential energy drives the brake pad 5 to separate from the support plate 3;

[0044] A bearing component 7, used to connect the brake pad 5 and the elastic beam 6;

[0045] The driving component 8 pulls the elastic beams 6 toward each other, thereby indirectly driving the brake pads 5 to be close to the support plate 3 .

[0046] Specifically in practical applications, the present application is a brake mechanism in a contracting machine. The support disc 3 is kept in a stable state by the action of the support wheel 2. Before use, the cable disc is first fixed on the cable rack 4, and then the cable is manually withdrawn. The external main drive motor and main reducer can drive the support disc 3 and the cable rack 4 to rotate as a whole to perform the contracting operation.

[0047] When parking is required, the driving component 8 is controlled to work, and the driving component 8 drives the upper ends of the two elastic beams 6 to approach each other. The elastic beam 6 drives the brake pad 5 to approach the support disk 3 through the bearing component 7. The brake pad 5 contacts the support disk 3. Through the continuous pressure of the driving component 8, the pressure between the brake pad 5 and the support disk 3 gradually increases, and finally the effect of rapid braking is achieved.

[0048] Reference Figure 1 、 Figure 5 and Figure 6 The elastic beam 6 is divided into channel steel 1 61, channel steel 2 62 and square steel 63. Channel steel 1 61 and channel steel 2 62 are arranged back to back, and square steel 63 is arranged between channel steel 1 61 and channel steel 2 62. The wall thickness of square steel 63 becomes thinner from bottom to top, and the lower end of the elastic beam 6 is fixedly connected to the foundation pit.

[0049] Specifically, in practical applications, the arrangement of the channel steel 1 61 and the channel steel 2 62 can enhance the structural strength of the overall elastic beam 6, and the arrangement of the square steel 63 at intervals can connect the channel steel 1 61 and the channel steel 2 62 while making the elastic beam 6 have better toughness.

[0050] By arranging the square steel 63 so that the wall thickness gradually becomes thinner from bottom to top, the elasticity of the upper end of the elastic beam 6 is increased.

[0051] The first embodiment of the driving component 8 is shown in FIG. Figure 1 and Figure 2 The driving component 8 includes a lifting ring 81 fixedly installed on the upper end of the elastic beam 6, a triangular plate 82 is installed on the upper end of the elastic beam 6 on the other side, the triangular plate 82 is hinged to 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.

[0052] Specifically in actual application, when braking is required, the first hydraulic cylinder 84 is controlled to extend, and the first hydraulic cylinder 84 drives one end of the triangular plate 82 to rotate counterclockwise, and the other end of the triangular plate 82 pulls the connecting rod 83, so that the upper ends of the elastic beams 6 are close to each other, and the elastic beams 6 indirectly drive the brake pads 5 to brake the support disc 3.

[0053] The second embodiment of the driving component 8 is shown in FIG. Figure 1 、 Figure 2 and Figure 7 The driving component 8 includes an internal threaded tube 85 fixedly mounted on the upper end of the elastic beam 6 on one side, a reduction motor 86 is mounted on the upper end of the elastic beam 6 on the other side, and a rotating rod 87 is mounted on the rotating end of the reduction motor 86. One end of the rotating rod 87 is threadedly connected to the internal threaded tube 85.

[0054] Specifically in actual application, when braking is required, the reduction motor 86 is controlled to rotate forward, and the reduction motor 86 drives the rotating rod 87 to rotate. The rotating rod 87 and the internal threaded tube 85 are in a screwed-in state. The upper ends of the two elastic beams 6 are tightened by rotating the rotating rod 87, thereby indirectly achieving the purpose of braking. The elastic beam 6 can be released by reversing the reduction motor 86.

[0055] Reference Figure 1 and Figure 8 The support plate 3 has a hole 31 on its side wall, and the cable rack 4 has a hole 32. The hole 32 corresponds to the position of the hole 31. A pin 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.

[0056] Specifically in actual application, the two ends of the cable rack 4 and the support wheel 2 are in a rotatable state, and the pin shaft 33 is inserted into the hole 1 31 and the hole 2 32 to make the cable rack 4 and the support plate 3 in a relatively fixed state, preventing the cable rack 4 from rotating freely during operation.

[0057] The embodiment 1 of the bearing member 7 has a stable structure, but the cost is relatively high. Figure 1 、 Figure 2 、 Figure 3 and Figure 4The bearing component 7 includes an arc-shaped box body 71 installed on the hinge plate 64. Both sides of the arc-shaped box body 71 are hinged to the hinge plate 64. One side of the arc-shaped box body 71 is arc-shaped and fits with the support plate 3. The brake pad 5 is installed on the arc-shaped surface of the arc-shaped box body 71.

[0058] Specifically in actual application, the hinge plate 64 is fixedly connected to the elastic beam 6, and the arc box 71 is installed on the hinge plate 64 in a freely rotatable state. The elastic beam 6 drives the arc box 71 and the brake pad 5 to stick to the surface of the support plate 3, thereby achieving a braking effect. Through the elastic force of the elastic beam 6 itself, a gap is created between the support plate 3 and the brake pad 5.

The air enters the arc-shaped box body 71 from the vent holes 712 at the lower end and both sides, and is discharged from the vent holes 712 at the upper end of the arc-shaped box body 71, taking away the heat from the heat dissipation hole 711; the side wall of the support plate 3 is installed with a wind plate 714, which fans the air flow.

[0060] Specifically in actual application, when the support plate 3 rotates, it drives the wind plate 714 to revolve, and the wind plate 714 fans the air flow around the brake pad 5 to flow quickly. The shape of the wind plate 714 can increase the air flow; frequent braking causes the brake pad 5 to have a higher temperature, and the high-temperature air flow diffuses into the arc box 71 through the heat dissipation holes 711, and the cold air flows into the arc box 71 from the air vents 712 at the lower end and both sides, and is discharged from the air vents 712 at the upper end of the arc box 71. At the same time, the heat is taken away by the heat dissipation holes 711, thereby achieving an air-cooling effect.

[0061] The second embodiment of the bearing component 7 has a simple structure, low cost and good heat dissipation performance. Figure 1 and Figure 5 The bearing component 7 includes an arc-shaped plate 72 mounted on the hinge plate 64 , a curved plate 73 is mounted on one side of the arc-shaped plate 72 , and the brake pad 5 is mounted on the surface of the curved plate 73 .

[0062] Specifically in actual application, the curvature of the arc plate 72 fits the support plate 3, the curved plate 73 is fixedly connected to the arc plate 72, the brake pad 5 is fixedly connected to the curved plate 73, and the curved plate 73 is connected to the elastic beam 6 through the hinge plate 64.

[0063] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4An elastic sheet 641 is installed on the hinged plate 64, and a sound-generating protrusion 642 is provided on the annular surface of the support disk 3. The thinning of the brake pad 5 can reduce the distance between the elastic sheet 641 and the sound-generating protrusion 642. There are multiple groups of sound-generating protrusions 642, and each group of sound-generating protrusions 642 is arranged at intervals. There are multiple sound-generating protrusions 642 in each group; a tension spring 76 is installed between the upper end of the bearing component 7 and the elastic beam 6, and the bearing component 7 remains in a vertical state.

[0064] Specifically in actual application, as the brake pad 5 is consumed, the thickness of the brake pad 5 gradually becomes thinner. When it becomes thin to a critical value, the elastic sheet 641 contacts the sound-emitting protrusion 642. When the support plate 3 rotates again, it will emit a regular high-frequency sound to remind the staff to perform the replacement operation.
