Description

Technical Field

[0001] This utility model relates to a ring-type braking mechanism, belonging to the technical field of ring-type braking mechanisms. Background Technology

[0002] Currently, the turntable end face contact brake structure, commonly known as the disc brake structure, achieves effective anti-loosening through the static friction torque generated between the contact end faces.

[0003] In actual use, brake pads gradually wear down due to friction with the rotating shaft, resulting in increased braking clearance and decreased braking performance. Therefore, traditional braking mechanisms typically require manual replacement of the entire braking system after the brake pads wear out, which shortens the lifespan of the brake pads and increases the operating cost of the braking system.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide a ring-shaped braking mechanism that addresses the issue in existing technologies where brake pads gradually wear down due to friction with the rotating shaft during actual use, leading to increased braking clearance and reduced braking performance. Therefore, traditional braking mechanisms typically require manual replacement of the entire mechanism after brake pad wear, resulting in a relatively short lifespan for the brake pads and high operating costs.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a ring-type braking mechanism, including a braking assembly, the braking assembly including a brake ring, a brake base provided on the brake ring, a brake pad sleeved inside the brake ring, a mounting seat provided on the brake ring, a plurality of positioning grooves through the brake pad, an adjusting plate slidably connected in the positioning groove, slide rail grooves provided on opposite sides of the positioning groove, a plurality of positioning pins inserted into the slide rail grooves fixedly connected on opposite sides of the adjusting plate, an adjusting mechanism provided on the adjusting plate, the adjusting mechanism enabling the adjusting plate to extend into the brake pad through the positioning groove.

[0007] The present invention is further configured such that: the adjustment mechanism includes a movable groove formed on the adjustment plate, a support block is slidably connected in the movable groove, a slot is formed on the inner wall of the positioning groove near the support block, and a positioning mechanism is provided in the brake plate, which can fix the support block in the slot.

[0008] By adopting the above technical solution, in the initial state, the upper surface of the support block is in contact with the top wall of the positioning groove, and at this time the bottom wall of the positioning groove is in contact with the lower surface of the adjusting piece. At this time, the adjusting piece is located in the positioning groove and does not extend into the brake pad. When brake pads wear down and increased braking friction is needed, the adjusting plate needs to be pushed upwards. Because the upper surface of the support block abuts against the top wall of the positioning groove, the positioning groove cannot move upwards synchronously with the adjusting plate. However, because the positioning pin slides within the slide rail groove, and the slide rail groove is inclined, the adjusting plate moves upwards synchronously through the positioning groove towards the center of the brake pad, extending into the brake pad. When the brake assembly is activated, causing the brake pad to deform inwards, the brake pad simultaneously moves the adjusting plate closer to the rotating shaft, pressing it tightly against the outer surface of the rotating shaft to brake it. This extension of the adjusting plate into the brake pad allows the brake pad to extend into the brake pad after wear, thus braking the rotating shaft. This increases the service life of the ring-type brake mechanism, reduces maintenance costs, lowers the replacement frequency of the ring-type brake mechanism, and increases its practicality.

[0009] The present invention is further configured such that: the positioning mechanism includes a sliding groove formed on one side of the slot, a positioning block is slidably connected in the sliding groove, a fixing spring is provided in the sliding groove, one end of the fixing spring is fixedly connected to the positioning block, the other end of the fixing spring is fixedly connected to the inner wall of the sliding groove, and a slot is formed on the support block, so that the positioning block can be inserted into the slot.

[0010] The present invention is further configured such that: a plurality of positioning tension springs are fixedly connected to one side of the support block, the end of the positioning tension spring away from the support block is fixedly connected to the inner wall of the movable groove, and a stabilizing component for increasing the stability of the support block is provided in the adjusting plate.

[0011] The present invention is further configured such that: the stabilizing component includes a connecting groove formed in the adjusting plate, the connecting groove is connected to the movable groove, a stabilizing block is slidably connected in the connecting groove, and the stabilizing block is fixedly connected to the support block.

[0012] The present invention is further configured such that a support spring is fixedly connected to the stabilizing block, and the end of the support spring away from the stabilizing block is fixedly connected to the inner wall of the connecting groove.

[0013] By adopting the above technical solution, during the upward movement of the adjusting plate, because the upper surface of the support block is in contact with the top wall of the positioning groove, the positioning groove will not move upward with the adjusting plate. Instead, the positioning groove can only move towards the center of the brake pad. During this process, the support block extends into the movable groove, stretching the positioning spring and support spring, causing them to deform. When the adjusting plate slides upward to a suitable height, it pushes the support block, causing it to slide within the movable groove. This process aligns the support block with the slot, allowing it to insert into the slot. At this point, under the release force of the positioning spring and support spring, the support block is pushed into the slot, and the... The upper surface contacts the inclined surface of the positioning block and pushes the positioning block towards the fixed spring, thereby compressing the fixed spring and causing it to deform. When the support block slides in the slot until the slot aligns with the positioning block, the fixed spring releases its elasticity, causing the positioning block to slide into the slot, thus fixing the support block and preventing it from being pulled out of the slot. At the same time, the upper surface of the stabilizing block contacts the top wall of the connecting groove, thereby positioning the state of the adjusting plate and preventing it from moving downwards. This positions the adjusting plate as it extends into the brake pad, making the adjustment convenient, quick, and easy to position, thus improving the practicality of the wrap-around brake mechanism.

[0014] The beneficial effects of this utility model are: by extending the adjusting plate into the brake pad, the brake pad can be braked on the rotating shaft after wear, thus increasing the service life of the ring-type brake mechanism, reducing maintenance costs, and decreasing the replacement frequency of the ring-type brake mechanism, thereby increasing the practicality of the ring-type brake mechanism.

Detailed Implementation

[0023] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figures 1 to 6 As shown, this utility model is further illustrated.

[0024] like Figures 1 to 3 As shown, this utility model is a ring-type braking mechanism, including a brake assembly, a brake ring 1, a pressure oil chamber, a rotating shaft, a brake base 6 on the brake ring 1, a brake pad 2 inside the brake ring 1, the rotating shaft passing through the brake pad 2, a mounting seat 3 on the brake ring 1, the brake base 6 and the mounting seat 3 being fixedly connected by countersunk screws, the brake ring 1 being fixed to the brake base 6 by countersunk screws, the brake base 6 being fixedly connected to the mounting seat 3 by countersunk screws, multiple positioning grooves 4 being formed through the brake pad 2, the positioning grooves 4 being arranged circumferentially around the brake pad 2, an adjusting piece 5 being slidably connected in the positioning grooves 4, slide rail grooves 9 being formed on opposite sides of the positioning grooves 4, the slide rail grooves 9 being inclined, multiple positioning pins 8 being fixedly connected to opposite sides of the adjusting piece 5 and inserted into the slide rail grooves 9, an adjusting mechanism being provided on the adjusting piece 5, the adjusting mechanism enabling the adjusting piece 5 to extend into the brake pad 2 through the positioning grooves 4.

[0025] like Figures 5 to 6 As shown, the adjustment mechanism includes a movable groove 7 on the adjustment plate 5. The movable groove 7 is located on the side of the adjustment plate 5 near the mounting base 3. A support block 10 is slidably connected in the movable groove 7. The support block 10 extends out of the outer side of the adjustment plate 5 through the movable groove 7. The side of the support block 10 away from the adjustment plate 5 abuts against the inner wall of the positioning groove 4. A slot 12 is provided on the inner wall of the positioning groove 4 near the support block 10. A positioning mechanism is provided in the brake pad 2. The positioning mechanism can fix the support block 10 in the slot 12.

[0026] In this solution, when braking is required, pressurized oil enters the pressurized oil chamber of the brake ring 1 and presses the thin-walled part of the brake ring 1 inward, causing it to deform inward. This causes the brake pad 2 to deform, making the inner wall of the brake pad 2 in close contact with the outer surface of the rotating shaft, generating a sufficiently large braking torque to stop the rotating shaft from rotating, thus completing the braking. The brake assembly, pressurized oil chamber, brake ring 1, brake base 6, and mounting base 3 are all prior art in the existing published patent: CN205136427U turntable encircling brake structure, and will not be described in detail here.

[0027] In the initial state, the upper surface of the support block 10 is in contact with the top wall of the positioning groove 4, and the bottom wall of the positioning groove 4 is in contact with the lower surface of the adjusting piece 5. At this time, the adjusting piece 5 is located in the positioning groove 4 and does not extend into the brake pad 2. When brake pad 2 wears down and requires increased braking friction, the adjusting plate 5 needs to be pushed upwards. Because the upper surface of the support block 10 abuts against the top wall of the positioning groove 4, the positioning groove 4 cannot move upwards synchronously with the adjusting plate 5. However, because the positioning pin 8 slides within the slide rail groove 9, and the slide rail groove 9 is inclined, the adjusting plate 5 moves upwards synchronously through the positioning groove 4 towards the center of the brake pad 2, thus extending into the brake pad 2. When the brake assembly is activated, causing the brake pad 2 to deform inwards, the brake pad 2 will synchronously move the adjusting plate 5 towards the direction closer to the rotating shaft, pressing the adjusting plate 5 tightly against the outer surface of the rotating shaft to brake it. By extending the adjusting plate 5 into the brake pad 2, the brake pad 2, after wear, can extend into the brake pad 2 to brake the rotating shaft. This increases the service life of the ring-type brake mechanism, reduces maintenance costs, lowers the replacement frequency of the ring-type brake mechanism, and thus increases its practicality.

[0028] like Figure 6 As shown, the positioning mechanism includes a sliding groove 14 on one side of the slot 12, a positioning block 13 slidably connected in the sliding groove 14, a fixing spring 15 provided in the sliding groove 14, one end of the fixing spring 15 being fixedly connected to the positioning block 13, and the other end of the fixing spring 15 being fixedly connected to the inner wall of the sliding groove 14. The extension path of the fixing spring 15 is consistent with the sliding path of the positioning block 13. The side of the positioning block 13 away from the fixing spring 15 extends into the slot 12 and is inclined. The inclined surface of the positioning block 13 is such that the adjusting piece 5 is inclined in the direction away from the fixing spring 15. A slot 11 is provided on the support block 10, and the positioning block 13 can be inserted into the slot 11.

[0029] like Figures 5 to 6As shown, a plurality of positioning springs 19 are fixedly connected to one side of the support block 10. The end of the positioning spring 19 away from the support block 10 is fixedly connected to the inner wall of the movable groove 7. The extension and retraction path of the positioning spring 19 is consistent with the sliding path of the support block 10. A stabilizing component for increasing the stability of the support block 10 is provided inside the adjusting plate 5.

[0030] like Figure 6 As shown, the stabilizing component includes a connecting groove 16 formed in the adjusting plate 5. The connecting groove 16 communicates with the movable groove 7. A stabilizing block 17 is slidably connected in the connecting groove 16. The stabilizing block 17 is fixedly connected to the support block 10.

[0031] As shown in the figure Figure 6 As shown, a support spring 18 is fixedly connected to the stabilizing block 17. The end of the support spring 18 away from the stabilizing block 17 is fixedly connected to the inner wall of the connecting groove 16. The extension and retraction path of the support spring 18 is consistent with the sliding path of the stabilizing block 17.

[0032] Furthermore, during the upward movement of the adjusting piece 5, because the upper surface of the support block 10 is in contact with the top wall of the positioning groove 4, the positioning groove 4 will not move upward with the adjusting piece 5. Instead, the positioning groove 4 can only move towards the center of the brake pad 2 with the adjusting piece 5. During this process, the support block 10 extends into the movable groove 7, thus stretching the positioning spring 19 and the support spring 18, causing them to deform. When the adjusting piece 5 slides upward to a suitable height, it pushes the support block 10, causing it to slide within the movable groove 7. This process aligns the support block 10 with the slot 12, causing it to insert into the slot 12. At this point, under the release force of the positioning spring 19 and the support spring 18, the support block 10 is pushed into the slot 12, and its upper surface... The surface of the support block 10 contacts the inclined surface of the positioning block 13 and pushes the positioning block 13 towards the fixed spring 15, thereby squeezing the fixed spring 15 and causing it to deform. When the support block 10 slides in the slot 12 until the slot 11 aligns with the positioning block 13, the positioning block 13 slides into the slot 11 under the release force of the fixed spring 15, thereby fixing the support block 10 and preventing it from being pulled out of the slot 12. At this time, the upper surface of the stabilizing block 17 contacts the top wall of the connecting groove 16, thereby positioning the state of the adjusting piece 5 and preventing it from moving downward. This positions the adjusting piece 5 as it extends into the brake pad 2, making the adjustment of the adjusting piece 5 convenient, quick, and simple, thus improving the practicality of the ring-type brake mechanism.
