Technical Field

[0001] This utility model relates to the technical field of safety protection equipment for electric shovels in open-pit mines, and in particular to a shovel lifting section cover brake. Background Technology

[0002] As one of the main mining equipment in the Baiyun Iron Mine, the WK series electric shovel is prone to slippage when moving long distances uphill on steep and long slopes during open-pit mining operations. Although preventative measures are in place, such as checking and adjusting the travel brake and adjusting the bucket placement, the shovel can still slip rapidly downhill if the operating system malfunctions due to the shovel tripping and the brake failing, potentially causing serious accidents. Previously, the method of using a loader to tow a shovel cover along with the shovel's lifting section had issues with misalignment or delayed placement of the shovel cover, posing serious safety hazards to operators and equipment.

[0020] 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.

[0021] The purpose of this utility model is to provide a shovel lifting section shroud brake to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the safety of shovel lifting section operation, and effectively reduces the risk of slippage and loss of control.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a shovel lifting section shroud brake, such as... Figures 1-3 As shown, the device includes: a bracket 1, an energized strong magnet 3, a slide plate 6, a shovel brake 9, and connecting parts. The bracket 1 is used to install on the electric shovel body; the energized strong magnet 3 is set on the bracket 1; the slide plate 6 can be attracted by the magnetic force generated when the energized strong magnet 3 is energized; the connecting parts are used to connect the slide plate 6 and the shovel brake 9; when the energized strong magnet 3 is de-energized, it loses its magnetic force, releasing the slide plate 6, causing the shovel brake 9 to fall and achieve shovel braking. This structural design clearly defines the main components and functional relationships of the shovel shovel lifting section's shovel brake. The bracket 1 serves as the installation base, ensuring a stable connection between the device and the electric shovel body; the energized strong magnet 3 uses magnetic force to attract and release the slide plate 6, thereby controlling the state of the shovel brake 9, achieving rapid braking, effectively solving the problem of easy slippage during the lifting section of the electric shovel, and ensuring the safety of equipment and personnel.

[0024] In a preferred embodiment, the bracket 1 is provided with a triangular reinforcing rib 2, and an energized strong magnet 3 is disposed in the middle of the triangular reinforcing rib 2. The triangular reinforcing rib 2 enhances the structural strength and stability of the bracket 1, enabling it to better withstand the forces exerted by the energized strong magnet 3 and the entire device during operation. Placing the energized strong magnet 3 in the middle of the triangular reinforcing rib 2 ensures the stable installation of the energized strong magnet 3, preventing it from shifting in the vibration environment of electric shovel operation, and ensuring the reliable operation of the entire braking device.

[0025] In a preferred embodiment, the energized strong magnet 3 has a trapezoidal structure, with an electromagnetic post 4 in the middle and a wire terminal 5 at the top of the electromagnetic post 4. The trapezoidal structure of the energized strong magnet 3 facilitates better integration with the bracket 1, increasing the contact area and the reliability of the connection. The electromagnetic post 4 and the wire terminal 5 provide a conductive path for the energized strong magnet 3, making it easier to control its power supply via wires and ensuring that the power can be quickly cut off when needed, thus enabling the rapid release of the chock brake 9.

[0026] In a preferred embodiment, the slide plate 6 has a cuboid structure. A lug 7 is provided on the side of the slide plate 6 away from the energized strong magnet 3. The connecting component is a steel wire rope 8 attached to the lug 7. The cuboid structure of the slide plate 6 provides a larger force-bearing area, enabling it to better withstand the magnetic attraction of the energized strong magnet 3 and the tension experienced when releasing the chock brake 9, ensuring safe and reliable operation. The lug 7 and steel wire rope 8 facilitate the connection between the slide plate 6 and the chock brake 9. Furthermore, the steel wire rope 8 possesses a certain degree of flexibility, allowing it to adapt to certain swings and displacements during device operation, ensuring the stability of the connection.

[0027] In a preferred embodiment, the chock brake 9 is provided with a wire rope drag hole 10, and the other end of the wire rope 8 is connected to the wire rope drag hole 10. The wire rope drag hole 10 provides a fixing point for the connection between the wire rope 8 and the chock brake 9, making the connection more stable. This connection method ensures that after the trailer plate 6 is released, the chock brake 9 can fall accurately under the traction of the wire rope 8, achieving reliable chock braking and improving braking accuracy.

[0028] In a preferred embodiment, the bottom of the shovel brake 9 is flat, the sides are arc-shaped, and the top is a slanted triangular structure. The flat bottom structure allows for full contact with the ground when shoveling the vehicle, providing greater friction and effectively preventing the electric shovel from sliding down. The arc-shaped sides facilitate smooth movement of the shovel brake 9 during descent, reducing interference with surrounding objects. The slanted triangular structure at the top helps guide the shovel brake 9 to accurately fall to the predetermined position while reducing its own weight, enabling it to respond to braking needs more quickly, thus improving the overall efficiency and reliability of the shovel brake.

[0029] In a preferred embodiment, the bracket 1 has a bracket block at its bottom, which is used to mount the bracket 1 onto the electric shovel body. The bracket block provides a convenient connection between the bracket 1 and the electric shovel body, enhancing the robustness of the connection. The bracket block allows the entire vehicle braking device to be mounted more stably on the electric shovel, adapting to the complex working conditions during electric shovel operation and ensuring that the braking device functions normally under various circumstances.

[0030] In a preferred embodiment, the wire terminal 5 is electrically connected to the emergency brake pedal in the cab via a wire. This connection cuts off the power supply to the energized magnet 3 when the emergency brake pedal is depressed. This electrical connection design allows the driver to directly control the shovel braking device from inside the cab. When the driver discovers an emergency such as the electric shovel slipping, simply pressing the emergency brake pedal quickly cuts off the power supply to the energized magnet 3, causing the shovel brake 9 to drop rapidly and achieve braking. This significantly improves the braking response speed, promptly ensures the safety of equipment and personnel, and enhances the overall ease of operation and safety of the device.

[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
