Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of braking mechanisms for crushing equipment, specifically an emergency braking mechanism for abnormal operation of stone crushing equipment. Background Technology
[0002] In industries such as mining and construction, crushers are commonly used crushing equipment. Crushers typically use a rotor disc to drive hammers to rotate at high speed to crush materials. When a crusher encounters an emergency during operation, it needs to brake. Existing braking devices are usually brake calipers and brake discs. Due to the weight and inertia of the hammers, the impact force of the hammers on the braking components during braking is large. Moreover, existing braking structures often lack effective buffering and stabilizing structures, resulting in rapid wear of braking components and a short service life.
[0003] Therefore, an emergency braking mechanism based on abnormal operation of stone crushing equipment is proposed to solve the problems mentioned above. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an emergency braking mechanism for abnormal operation of stone crushing equipment. Through a forward-moving mechanism and a baffle mechanism, the inner brake housing is rotated and moved into the crusher housing, causing the outer brake baffle to quickly extend into the crusher housing to block the hammer. When the hammer impacts the outer brake baffle, the kinetic energy of the hammer is converted into the elastic potential energy of the spring, causing the hammer to decelerate. At the same time, the arc spring and hydraulic damper can buffer the impact force of the hammer impact, thus solving the problems mentioned in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a crusher housing, a baffle mechanism, and a forward moving mechanism. A rotating shaft is rotatably connected inside the crusher housing, and a rotor disk is fixedly installed on the outer surface of the rotating shaft. A hammer is rotatably connected to the rotor disk through a shaft. Brake housings are fixedly connected to opposite sides of the outside of the crusher housing. The baffle mechanism and the forward moving mechanism are installed inside the brake housing.
[0006] The baffle mechanism includes an outer brake baffle, an inner brake housing, and an arc spring;
[0007] The forward movement mechanism includes a mounting plate and a second telescopic rod;
[0008] Preferably, one end of the outer brake baffle is rotatably connected to the inner brake housing, and both ends of the arc-shaped spring are fixedly connected to the outer brake baffle and the inner brake housing, respectively.
[0009] Preferably, one end of the second telescopic rod is fixedly connected to the crusher housing, and the other end of the second telescopic rod is fixedly connected to the mounting plate.
[0010] Preferably, the mounting plate has multiple connecting blocks on one side near the second telescopic rod, and the connecting blocks are rotatably connected to the brake inner housing.
[0011] Preferably, a telescopic rod is provided between the brake inner housing and the connecting block, one end of the telescopic rod is rotatably connected to the brake inner housing, and the other end of the telescopic rod is rotatably connected to the connecting block.
[0012] Preferably, a hydraulic damper is rotatably connected to one side of the outer brake baffle near the inner brake housing, and the other end of the hydraulic damper is rotatably connected to the inner brake housing.
[0013] Preferably, a limiting slider is fixedly connected to the middle of the arc-shaped spring, and both the limiting slider and the inner brake housing are provided with arc-shaped sliding grooves. Arc-shaped sliding rails are provided on the opposite sides of the outer brake baffle.
[0014] Compared with the prior art, this utility model provides an emergency braking mechanism for abnormal operation of stone crushing equipment, which has the following beneficial effects:
[0015] 1. Through the forward moving mechanism and the baffle mechanism, the inner brake housing is pushed to rotate and move into the crusher housing at the same time, so that the outer brake baffle can quickly extend into the crusher housing to block the hammer. When the hammer hits the outer brake baffle, the kinetic energy of the hammer is converted into the elastic potential energy of the spring, which slows down the hammer. At the same time, the arc spring and the hydraulic damper can buffer the impact force of the hammer. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1 - Figure 7 This embodiment provides an emergency braking mechanism for abnormal operation of a stone crushing equipment, including a crusher housing 1, a baffle mechanism 2, and a forward movement mechanism 3. A rotating shaft is rotatably connected inside the crusher housing 1, and a rotor disk 4 is fixedly installed on the outer surface of the rotating shaft. Hammers 5 are rotatably connected to the rotor disk 4 via a shaft. The rotating shaft provides rotational support for the rotor disk 4. The rotor disk 4 is used to install the hammers 5 and drive the hammers 5 to rotate to complete the crushing operation. The hammers 5 directly contact the stone to achieve crushing. Brake housings 6 are fixedly connected to opposite sides of the crusher housing 1. The baffle mechanism 2 and the forward movement mechanism 3 are installed inside the brake housings 6. The brake housings 6 serve to accommodate and protect the baffle mechanism 2 and the forward movement mechanism 3.
[0028] The baffle mechanism 2 includes an outer brake baffle 201, an inner brake housing 202, and an arc spring 203. The forward movement mechanism 3 includes a mounting plate 301 and a second telescopic rod 302. During emergency braking, one end of the outer brake baffle 201 is rotatably connected to the inner brake housing 202, allowing the outer brake baffle 201 to rotate relative to the inner brake housing 202. Both ends of the arc spring 203 are fixedly connected to the outer brake baffle 201 and the inner brake housing 202, respectively. The arc spring 203 can deform when the outer brake baffle 201 is struck by the hammer 5, converting the kinetic energy of the hammer 5 into its own elastic potential energy, thereby decelerating the hammer 5. A hydraulic damper 9 is rotatably connected to the side of the outer brake baffle 201 closest to the inner brake housing 202. The hydraulic damper 9... One end is rotatably connected to the inner brake housing 202. The hydraulic damper 9 can generate damping during the rotation of the outer brake baffle 201, further absorbing impact energy and reducing the impact force of the outer brake baffle 201 on the equipment housing. The middle of the arc spring 203 is fixedly connected to the limiting slider 10. Both the limiting slider 10 and the inner brake housing 202 are provided with arc-shaped grooves 11. The outer brake baffle 201 is provided with arc-shaped slide rails 12 on opposite sides inward. The limiting slider 10 limits the arc spring 203, making the arc spring 203 more stable during contraction and release. The limiting slider 10 cooperates with the arc-shaped grooves 11 and the arc-shaped slide rails 12 to limit the movement trajectory of the arc spring 203, ensuring that it will not deviate during operation and ensuring the stability of the buffering effect.
[0029] One end of the second telescopic rod 302 is fixedly connected to the crusher housing 1, and the other end is fixedly connected to the mounting plate 301. The second telescopic rod 302 drives the mounting plate 301 to move through its telescopic movement, providing power for the position adjustment of the braking mechanism. A plurality of connecting blocks 7 are provided on one side of the mounting plate 301 near the second telescopic rod 302. The connecting blocks 7 are rotatably connected to the brake inner housing 202. The connecting blocks 7 connect the mounting plate 301 and the brake inner housing 202 on one hand, and provide a fulcrum for the rotation of the brake inner housing 202 on the other hand. A first telescopic rod 8 is provided between the brake inner housing 202 and the connecting blocks 7. Both the first telescopic rod 8 and the second telescopic rod 302 are electric telescopic rods. One end of the first telescopic rod 8 is rotatably connected to the brake inner housing 202, and the other end is rotatably connected to the connecting block 7. The first telescopic rod 8 pushes the brake inner housing 202 to rotate around the connecting block 7 through its telescopic movement, thereby driving the brake outer baffle 201 to adjust its angle.
[0030] During emergency braking, the second telescopic rod 302 retracts, causing the mounting plate 301 to move. As the mounting plate 301 moves, it moves the connecting block 7 and the baffle mechanism 2. Simultaneously, the first telescopic rod 8 of the baffle mechanism 2 extends. The connecting block 7 is rotatably connected to the inner brake housing 202. When the first telescopic rod 8 extends, it pushes the inner brake housing 202 to rotate around the connection point. One end of the outer brake baffle 201 is rotatably connected to the inner brake housing 202. The two ends of the arc-shaped spring 203 are fixedly connected to the outer brake baffle 201 and the inner brake housing 202, respectively. When the inner brake housing 202 rotates, it causes the outer brake baffle 201 to rotate, causing the end of the outer brake baffle 201 away from the shaft to extend into the crusher housing 1. The side of the outer brake baffle 201 away from the inner brake housing 202 is inclined inside the crusher housing 1. This inclined surface is used to block the rotation of the hammer 5. When the hammer 5 hits the inclined surface, it first contacts the low point of the inclined surface and moves towards the high point of the inclined surface. During this process, the resistance experienced by the hammer 5 gradually increases, and the kinetic energy of the hammer 5 is converted into the elastic potential energy of the spring, causing the hammer 5 to decelerate. After the hammer 5 passes the inclined surface, the outer brake baffle 201 extends again under the elastic force of the arc spring 203 to decelerate the hammer 5. During the rotation of the outer brake baffle 201, the hydraulic damper 9 reduces the impact force of the outer brake baffle 201 on the equipment housing, thereby achieving a smooth braking effect and reducing component wear.
[0031] Furthermore, the inclined surface design of the outer brake baffle 201 gradually increases the resistance to the hammer head 5, avoiding damage to the components caused by the instantaneous huge impact force. The re-extension of the outer brake baffle 201 under the action of the arc spring 203 can decelerate the hammer head 5 a second time, further improving the braking effect. The limit slider 10 ensures that the arc spring 203 can always stably play a buffering role.
[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
