Description

Technical Field

[0001] This utility model relates to the field of brake structure technology, specifically a single-piece electromagnetic brake with low failure rate. Background Technology

[0002] An electromagnetic brake is a connector that transmits torque from the active side to the passive side. It can be freely engaged, disengaged, or braked as needed. Electromagnetic brakes can be classified in various ways. According to the braking method, they can be divided into energized braking and de-energized braking. Electromagnetic brakes are widely used in machinery in metallurgy, construction, chemical industry, food industry, machine tools, stage, elevator, ship, packaging and other fields, as well as in braking situations when power is off (as a safety precaution).

[0003] According to the power source, existing technologies can be mainly divided into three categories: pneumatic, hydraulic, and electromagnetic. Among them, pneumatic and hydraulic brakes require special energy storage devices. These two types of brakes often experience air or liquid leakage, have a high mechanical failure rate, and pose certain safety hazards. In order to solve the above technical problems, it is necessary to design a single-piece electromagnetic brake with a low failure rate. Utility Model Content

[0004] The purpose of this invention is to provide a single-piece electromagnetic brake with a low failure rate, which has the advantages of good braking effect, low failure rate, dust prevention and early warning, and solves the problems of high failure rate, low reliability and low safety of brake structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-piece electromagnetic brake with low failure rate, comprising a magnetic yoke, an armature disposed on the right side of the magnetic yoke, a connecting ring disposed on the right side of the armature, a groove formed on the right side of the connecting ring, a partition plate fixedly connected to the inner wall of the groove, a bolt being installed through the right side of the partition plate, a threaded hole formed on the surface of the armature, the left side of the bolt penetrating into the inner cavity of the threaded hole and threadedly connected to the threaded hole, a first ring fixedly sleeved on the surface of the armature, a second ring fixedly sleeved on the surface of the connecting ring, and dust covers sleeved on the surfaces of the first ring and the second ring.

[0006] Preferably, the surface of the bolt is fitted with a sleeve, the left side of the sleeve passes through the connecting ring and is movably connected to the connecting ring, and the right side of the sleeve is located in the inner cavity of the groove.

[0007] Preferably, a first spring is sleeved on the surface of the bolt, with the right side of the first spring contacting the partition and the left side of the first spring contacting the sleeve.

[0008] Preferably, the inner wall of the groove is provided with a sliding groove, and a slider is fixedly connected to one side of the sleeve, with one side of the slider extending into the inner cavity of the sliding groove.

[0009] Preferably, a sealing ring is embedded on the right side of the armature, and the right side of the sealing ring contacts the connecting ring.

[0010] Preferably, an alarm mechanism is installed in the inner cavity of the groove. The alarm mechanism includes a first contact block, which is fixedly installed on the surface of the sleeve. A deep groove is fixedly connected to the inner wall of the groove. A movable block is movably connected to the inner cavity of the deep groove. One side of the movable block extends into the inner cavity of the groove and is fixedly connected to a second contact block. The first contact block and the second contact block cooperate with each other. A second spring is fixedly connected to the left side of the movable block. The left side of the second spring is fixedly connected to the inner wall of the deep groove.

[0011] Preferably, the first and second contact blocks are electrically connected to an alarm, the alarm is electrically connected to a controller, and the controller and the alarm are installed in the driver's cab.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a magnetic yoke, armature, connecting ring, groove, partition, bolt and threaded hole, can attract the armature after the magnetic yoke is energized, which can brake the armature and the connecting ring, and then brake the wheel drum connected to the connecting ring. The braking reliability is high, the failure rate is lower than that of hydraulic and pneumatic brakes, and the service life is long. It solves the problem of high failure rate and safety hazards of using pneumatic and hydraulic brake structures.

[0014] 2. This utility model supports the movable block and the second contact block by setting a second spring, ensuring close contact between the second contact block and the first contact block. By configuring the first contact block, the deep groove, the movable block, and the second contact block, during braking, the armature displacement and the magnetic yoke...

[0015] Contact friction causes the magnetic yoke to synchronously drive the first contact block to move. After the armature wears down to a certain thickness, the first contact block will come into contact with the second contact block, thereby triggering the alarm mechanism and prompting the driver to replace the armature, thus improving driving safety.

Detailed Implementation

[0021] Please see Figures 1-4 A single-piece electromagnetic brake with low failure rate includes a magnetic yoke 1, an armature 2 on the right side of the yoke 1, a connecting ring 3 on the right side of the armature 2, a groove 4 on the right side of the connecting ring 3, a partition 5 fixedly connected to the inner wall of the groove 4, a bolt 6 through the right side of the partition 5, a threaded hole 7 on the surface of the armature 2, the left side of the bolt 6 penetrating into the inner cavity of the threaded hole 7 and threadedly connected to the threaded hole 7, a first ring 8 fixedly sleeved on the surface of the armature 2, a second ring 9 fixedly sleeved on the surface of the connecting ring 3, and dust covers 10 covering the surfaces of the first ring 8 and the second ring 9. The system includes a magnetic yoke 1, an armature 2, a connecting ring 3, a groove 4, a partition 5, a bolt 6, and a threaded hole 7. When the magnetic yoke 1 is energized, it attracts the armature 2, which can brake the armature 2 and the connecting ring 3, thereby braking the wheel drum connected to the connecting ring 3. The braking reliability is high, the failure rate is lower than that of hydraulic and pneumatic brakes, and the service life is long. By setting a first ring 8, a second ring 9, and a dust cover 10, the space between the armature 2 and the connecting ring 3 is sealed and protected, preventing external dust from entering and contaminating the components, thus extending the service life of the brake structure. The connecting ring 3 facilitates connection with the external wheel drum.

[0022] Please see Figure 1 A sleeve 11 is fitted on the surface of the bolt 6. The left side of the sleeve 11 passes through the connecting ring 3 and is movably connected to the connecting ring 3. The right side of the sleeve 11 is located in the inner cavity of the groove 4. By setting the sleeve 11, the bolt 6 and the armature 2 are supported, which facilitates the lateral movement of the bolt 6 and the armature 2.

[0023] Please see Figure 1 A first spring 12 is fitted on the surface of the bolt 6. The right side of the first spring 12 contacts the partition 5, and the left side of the first spring 12 contacts the sleeve 11. By setting the first spring 12, the sleeve 11 is connected, which facilitates the return of the sleeve 11, the bolt 6 and the armature 2.

[0024] Please see Figure 2 The inner wall of the groove 4 is provided with a sliding groove 13, and a slider 14 is fixedly connected to one side of the sleeve 11. One side of the slider 14 extends into the inner cavity of the sliding groove 13. By setting the sliding groove 13 and the slider 14, the sleeve 11 is guided, which facilitates the lateral movement of the sleeve 11.

[0025] Please see Figure 1 A sealing ring 15 is embedded on the right side of the armature 2. The right side of the sealing ring 15 contacts the connecting ring 3. By setting the sealing ring 15, the armature 2 and the connecting ring 3 are sealed, thereby enhancing the sealing effect at this point.

[0026] Please see Figure 3 An alarm mechanism 16 is installed in the inner cavity of the groove 4. The alarm mechanism 16 includes a first contact block 160, which is fixedly installed on the surface of the sleeve 11. A deep groove 161 is fixedly connected to the inner wall of the groove 4. A movable block 162 is movably connected to the inner cavity of the deep groove 161. One side of the movable block 162 extends into the inner cavity of the groove 4 and is fixedly connected to a second contact block 163. The first contact block 160 and the second contact block 163 cooperate with each other. A second spring 164 is fixedly connected to the left side of the movable block 162. The left side of the second spring 164 is fixedly connected to the inner wall of the deep groove 161. By setting a second spring 164 to support the movable block 162 and the second contact block 163, the second contact block 163 is in close contact with the first contact block 160. By setting the first contact block 160, the deep groove 161, the movable block 162 and the second contact block 163, during the braking process, the armature 2 is displaced and comes into contact with the magnetic yoke 1. The magnetic yoke 1 synchronously drives the first contact block 160 to move. After the armature 2 is worn to a certain thickness, the first contact block 160 will come into contact with the second contact block 163, thereby triggering the alarm mechanism and prompting the driver to replace the armature 2, thus improving driving safety.

[0027] Please see Figure 3 The first contact block 160 and the second contact block 163 are electrically connected to an alarm, which is electrically connected to a controller. The controller and the alarm are installed in the cab. By setting the alarm and the controller, the driver is prompted to make an audible alarm to urge the driver to replace the armature 2 in time to ensure the subsequent safe braking of the equipment.

[0028] In use, the controller controls the yoke 1 to be energized, and the yoke 1 generates a magnetic force, causing the armature 2 to move to the left and engage with the yoke 1, thus braking the armature 2 and the connecting ring 3. The dust cover 10 seals the yoke 1 and the armature 2 to prevent dust. When adjusting the gap between the armature 2 and the yoke 1, the sleeve is connected to the bolt 6, and the bolt 6 is rotated to connect with the threaded armature 2, so that the armature 2 moves laterally, thereby adjusting the gap between the armature 2 and the yoke 1. This ensures that the armature 2 and the yoke 1 are in close contact during braking, resulting in a good braking effect.

[0029] During braking, the armature 2 is displaced and comes into contact with the magnetic yoke 1. The magnetic yoke 1 synchronously drives the sleeve 11 and the first contact block 160 to move to the left. After the armature 2 is worn to a certain thickness, the first contact block 160 will come into contact with the second contact block 163. After contact, the information is sent to the controller. The controller controls the alarm to sound an alarm, prompting the driver to replace the armature 2 to improve safety.

[0030] In summary, this low-failure-rate single-piece electromagnetic brake solves the problems of high failure rate, low reliability, and low safety of brake structures by setting up a magnetic yoke 1, armature 2, connecting ring 3, groove 4, partition 5, bolt 6, and threaded hole 7.
