Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a protective device for preventing rock splashing during mining operations. Background Technology

[0002] Mining relies on mechanical equipment to excavate ore layers, which greatly improves mining efficiency. However, the crushed rocks produced by the equipment can fly under strong force, which can easily endanger the personal safety of mining personnel. Therefore, it is necessary to install anti-flying rock devices.

[0003] An existing patent (publication number: CN219316981U) discloses a protective device for preventing rock splashing in mining operations. It uses iron chains to provide flexible protection against rock splashing in mining operations. When faced with large pieces of rock splashing directly, the chain slides along the column and adjusts its posture under strong force. During the extension of the iron chain, the force of the rock is gradually offset, and finally a hard interception is achieved. The interception force is improved while being relatively lightweight and easy to move and adjust.

[0004] In practical applications, the device proposed in the aforementioned patent can gradually offset the impact force of gravel through the iron chain in a flexible and rigid manner. However, the iron chain is prone to wear and jamming, and smaller gravel is easy to get stuck in the iron chain or splash out from the gaps between the iron chains. This can easily lead to jamming and damage during winding, and it cannot be folded and stored, making it inconvenient for transportation and placement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a protective device for preventing rock splashing in mining operations. It has the advantages of buffering and blocking rocks of different sizes, reducing the splashing of smaller rocks, and being foldable for storage, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mining crushing and splash protection device, comprising a base, two symmetrical first hinge blocks fixedly connected to the upper surface of the base, and a support column hinged to the first hinge blocks, a connecting rod fixedly connected to one side of the two support columns that are close to each other, an anti-splash mechanism provided on the circumferential surface of the connecting rod, a support component connected to the two support columns and a protective component fixed to the outer surface of the base on the upper surface of the base; The splash-proof mechanism includes several rotating rings sleeved on the circumferential surface of the connecting rod, and several sliding rods fixed to the inner wall of the reserved groove on the upper surface of the base. The circumferential surface of the sliding rod is slidably connected to a second hinge block, and the bottom surface of the second hinge block is slidably connected to the bottom wall of the reserved groove in the base. The connecting end of the second hinge block is hinged to a hinge rod, and a buffer component is provided between each rotating ring and the corresponding second hinge block.

[0007] Furthermore, the buffer assembly includes elastic components that are fixedly connected to the swivel connection end and the hinge rod connection end respectively, and a connecting plate is fixedly connected to one end of each of the two elastic components. Two connecting ropes are fixedly connected to one side of each of the two connecting plates, and several flexible plates are sleeved on the circumferential surface of the two connecting ropes.

[0008] With the above solution, when the flying debris impacts the flexible plate, the flexible plate will deform to a certain extent under the force, and at the same time, the force will be transmitted to the connecting rope. The impact force on the flexible plate and the connecting rope will move slightly under the sliding action of the second hinge block and the slide rod, thereby causing the flexible plate and the connecting rope to tilt to a certain extent. In conjunction with the elastic component, the impact force is doubly buffered and absorbed by its own elastic properties, effectively reducing the damage caused by the impact force of flying debris to the overall device and surrounding personnel and equipment, and improving the safety and stability of the mining operation.

[0009] Furthermore, each elastic component is composed of a damper and a spring coaxially combined to provide elastic cushioning force when the connecting rope and flexible plate are impacted by gravel, and to guide the component to return to its original position.

[0010] Through the above scheme, the damper can absorb and dissipate impact energy, effectively reducing the direct impact force on the device, while the spring can quickly restore the flexible plate and connecting rope to their initial positions after the impact, ensuring the continuous and stable operation of the device.

[0011] Furthermore, the flexible plate is made of rubber composite board, and the surface of the flexible plate has a circular arc protrusion structure. This circular arc protrusion structure is used to squeeze out the gravel that enters the gap when the flexible plates are reset.

[0012] With the above solution, the arc-shaped protrusions on the surface of the flexible plate can deform to a certain extent when impacted by gravel. This deformation not only does not damage the overall structure of the flexible plate, but also effectively squeezes out the gravel that has entered the gap during the reset process, thus preventing the gravel from getting stuck between the flexible plates and affecting its buffering performance.

[0013] Furthermore, a corrugated tube is fitted onto the outer surface of the elastic component, which is used to synchronously expand and contract with the elastic component and to block gravel.

[0014] With the above solution, the corrugated pipe is tightly attached to the outer surface of the elastic component. During the expansion and contraction of the elastic component, the corrugated pipe, with its own good flexibility and extensibility, can expand and contract synchronously with the elastic component and will not hinder the normal operation of the elastic component.

[0015] Furthermore, the support assembly consists of a third hinge block, a fourth hinge block, and a support rod. The two ends of the support rod are respectively hinged to the third hinge block and the fourth hinge block. The third hinge block is used to insert into a reserved hole on the upper surface of the base, and the fourth hinge block is inserted into a reserved hole on the outer surface of the support column on the same side. A storage groove is provided on the outer surface of the base.

[0016] Through the above scheme, by opening several slots on the upper surface of the base that are compatible with the third hinge block, the support rod, the third hinge block and the fourth hinge block can form a support structure with a flexible adjustable angle. The third hinge block is inserted into the reserved hole on the upper surface of the base to ensure a stable connection between the support component and the base, while the fourth hinge block is inserted into the reserved hole on the outer surface of the support column on the same side, so that the support component can fit tightly with the support column to jointly support the entire device.

[0017] Furthermore, casters are installed at the four corners of the base, and anchor plates are inserted into the slots reserved on the upper surface of the base.

[0018] Through the above design, the casters allow the entire device to move flexibly on the mining site, facilitating workers to adjust the device's position according to actual operational needs, thus improving the device's mobility and applicability. Furthermore, the protective assembly includes a protective plate fixed to the outer surface of the base, and triangular guide plates respectively fixed to the outer surfaces of the two support columns.

[0019] Through the above solution, the protective plate can effectively block the flying debris generated during mining, provide initial protection for the workers and equipment around the base, and limit and block the support column to prevent it from overturning.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This mining protection device for preventing rock splashes uses a buffer and elastic component in the anti-splash mechanism to provide both hard and flexible blocking and buffering of rock fragments generated during mining. The flexible plate design prevents smaller fragments from entering the gaps between the flexible plates and affecting the reset process, and also squeezes smaller fragments out of the gaps. At the same time, the elastic component resets the buffer component, effectively preventing damage caused by smaller fragments getting stuck between the flexible plates during reset.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figures 1 to 5 This embodiment of a mining crushing and splash protection device includes a base 1, two symmetrical first hinge blocks 2 are fixedly connected to the upper surface of the base 1, and a support column 3 is hinged to the first hinge blocks 2. A connecting rod 4 is fixedly connected to one side of the two support columns 3 that is close to each other. The circumferential surface of the connecting rod 4 is provided with a splash protection mechanism 5. The upper surface of the base 1 is provided with a support component connected to the two support columns 3, and a protective component fixed to the outer surface of the base 1.

[0025] The support column 3, which is hinged to the first hinge block 2 and works in conjunction with the support assembly, can be flexibly adjusted in angle to adapt to the requirements of preventing rock splashing in different mining scenarios. At the same time, the support assembly can further enhance the overall stability of the device, ensuring that the device can operate stably in complex mining environments. The anti-splash mechanism 5 can effectively block rock splashing generated during mining, ensuring the safety of operators.

[0026] As a supplement, the protective components fixed to the outer surface of the base 1 protect the base 1 from damage by external factors and extend the service life of the device.

[0027] The anti-splash mechanism 5 includes several rotating rings 501 sleeved on the circumferential surface of the connecting rod 4, and several sliding rods 502 fixed to the inner wall of a pre-reserved groove on the upper surface of the base 1. A second hinge block 503 is slidably connected to the circumferential surface of each sliding rod 502, and the bottom surface of the second hinge block 503 is slidably connected to the bottom wall of the pre-reserved groove in the base 1. A hinge rod 504 is hinged to the connecting end of the second hinge block 503. A buffer assembly is provided between each rotating ring 501 and the corresponding second hinge block 503. The rotating rings 501 can rotate flexibly on the connecting rod 4 to adapt to impacts from gravel in different directions. The sliding rods 502 provide a stable sliding track for the second hinge blocks 503, ensuring that the second hinge blocks 503 can move smoothly when subjected to external force. The buffer assembly can effectively absorb and disperse the energy generated by the impact of gravel, greatly reducing the risk of injury to workers from flying gravel, and further improving the anti-splash effect and safety of the device.

[0028] The buffer assembly includes elastic components 505 fixedly connected to the connecting end of the swivel 501 and the connecting end of the hinge rod 504, respectively. A connecting plate 506 is fixedly connected to one corresponding end of each elastic component 505. Two connecting ropes 507 are fixedly connected to one corresponding side of each connecting plate 506. Several flexible plates 508 are sleeved on the circumferential surface of each connecting rope 507. When flying debris impacts the flexible plates 508, the flexible plates 508 will deform to a certain extent under stress, simultaneously transmitting the force to the connecting ropes 507. The impact force on the flexible plates 508 and the connecting ropes 507 will be transmitted through the connecting ropes 507. The two hinge blocks 503 and the sliding rod move slightly under the sliding action, thereby causing the flexible plate 508 and the connecting rope to tilt to a certain extent. Together with the elastic component 505, the impact force is doubly buffered and absorbed by the elasticity of the component, which effectively reduces the damage caused by the impact force of the flying gravel to the overall device and surrounding personnel and equipment, and improves the safety and stability of the mining operation. In addition, the material of the flexible plate 508 has a certain degree of flexibility and wear resistance, and can maintain good buffering performance under repeated impacts from gravel, thus extending the service life of the buffer component.

[0029] Each elastic component 505 is composed of a damper and a spring coaxially combined. It provides elastic buffering force when the connecting rope 507 and flexible plate 508 are impacted by gravel, and guides the component to reset. The damper can absorb and dissipate impact energy, effectively reducing the direct impact force on the device, while the spring can quickly restore the flexible plate 508 and connecting rope 507 to their initial position after the impact, ensuring the continuous and stable operation of the device. Moreover, this elastic component 505 composed of a damper and a spring has a compact structure, occupies little space, and is easy to install and arrange in the device, further improving the overall performance and practicality of the device.

[0030] The flexible plate 508 is made of rubber composite board. The surface of the flexible plate 508 has an arc-shaped protrusion structure. This arc-shaped protrusion structure is used to squeeze out the gravel that enters the gap when several flexible plates 508 are reset. When the arc-shaped protrusion structure on the surface of the flexible plate 508 is impacted by gravel, it can undergo a certain degree of deformation. This deformation not only does not damage the overall structure of the flexible plate 508, but also effectively squeezes out the gravel that enters the gap during the reset process, avoiding the gravel from getting stuck between the flexible plates 508 and affecting its buffering performance. At the same time, the material of the rubber composite board gives the flexible plate 508 good anti-aging properties, which can be used for a long time in harsh mining environments without aging or cracking, further ensuring the reliability and stability of the device.

[0031] A corrugated tube 509 is fitted onto the outer surface of the elastic component 505. The corrugated tube 509 is used to expand and contract synchronously with the elastic component 505 and to block debris. The corrugated tube 509 fits tightly against the outer surface of the elastic component 505. During the expansion and contraction of the elastic component 505, the corrugated tube 509, with its good flexibility and extensibility, can expand and contract synchronously with the elastic component 505 without hindering the normal operation of the elastic component 505. Moreover, when debris is thrown, the corrugated tube 509 can form an effective barrier to prevent the debris from directly impacting the elastic component 505, thus avoiding damage to the elastic component 505 due to debris impact, thereby extending the service life of the elastic component 505 and further improving the protection capability of the entire device against debris splash during mining operations.

[0032] The support assembly consists of a third hinge block 6, a fourth hinge block 7, and a support rod 8. Both ends of the support rod 8 are hinged to the third hinge block 6 and the fourth hinge block 7, respectively. The third hinge block 6 is inserted into a pre-drilled hole on the upper surface of the base 1, and the fourth hinge block 7 is inserted into a pre-drilled hole on the outer surface of the support column 3 on the same side. A storage slot 9 is provided on the outer surface of the base 1. By creating several slots on the upper surface of the base 1 that are compatible with the third hinge block 6, the support rod 8, the third hinge block 6, and the fourth hinge block 7 form a support structure with an adjustable angle. The insertion of the third hinge block 6 into the pre-drilled hole on the upper surface of the base 1 ensures a stable connection between the support assembly and the base 1. The insertion of the fourth hinge block 7 into the pre-drilled hole on the outer surface of the support column 3 on the same side allows the support assembly to fit tightly with the support column 3, jointly supporting the entire device. The storage slot 9 on the outer surface of the base 1 can be used to store commonly used tools or accessories, making them readily available to workers during mining operations and improving work efficiency.

[0033] The base 1 has casters 10 installed at the four corners of its bottom surface. Anchor plates 11 are inserted into the slots reserved on the upper surface of the base 1. The design of the casters 10 allows the entire device to move flexibly on the mining site, making it convenient for workers to adjust the position of the device according to actual work needs, thus improving the mobility and applicability of the device. The anchor plates 11 are inserted into the slots reserved on the upper surface of the base 1. After the device is positioned, the anchor plates 11 can be further fixed to the ground, enhancing the stability of the device and preventing it from moving under the action of external forces such as flying gravel, thus ensuring that the device can effectively play its role in preventing flying debris.

[0034] The protective components include a protective plate 12 fixed to the outer surface of the base 1 and triangular guide plates 13 fixed to the outer surfaces of the two support columns 3. The protective plate 12 can effectively block the flying debris generated during mining, providing initial protection for the workers and equipment around the base 1, and limiting and blocking the support columns 3 to prevent them from overturning. The triangular guide plates 13, fixed to the outer surfaces of the two support columns 3, have a unique triangular shape design that can guide and divert the flying debris to both sides, further reducing the impact of the debris on the surrounding area of ​​the device. Together with the protective plate 12, they greatly enhance the anti-splash effect of the entire device, providing a more reliable safety guarantee for mining operations.

[0035] The working principle of the above embodiment is as follows: the universal wheel 10 of the base 1 moves to the protected area, the anchoring pile plate 11 is fixed to the ground to prevent displacement, and with the help of the hinged cooperation of the third hinge block 6, the fourth hinge block 7 and the support rod 8 in the support assembly, the support column 3 can be deflected around the first hinge block 2, so that the anti-splash mechanism 5 is accurately aligned with the direction of the flying gravel, and the protection angle is adapted.

[0036] When the gravel impacts the flexible plate 508, the flexible plate 508 deforms to unload the force and transmits the impact force to the connecting rope 507. The force is then transmitted to the elastic component 505 via the connecting plate 506. The spring in the elastic component contracts to buffer the impact, and the damper dissipates the kinetic energy. The rotating ring 501 rotates along the connecting rod 4 to adapt to the impact angle, thus achieving initial interception of the gravel.

[0037] When large pieces of gravel impact, the impact force drives the second hinge block 503 to slide along the slide bar 502, increasing the buffer stroke. The elastic component extends and retracts under full load to unload the force. The arc protrusions on the surface of the flexible plate 508 guide the gravel to deflect and slow down. The corrugated pipe 509 simultaneously blocks the gravel from impacting the elastic component, ensuring the stability of the unloading force.

[0038] After the impact ends, the elastic component spring rebound force drives the connecting rope 507, flexible plate 508 and second hinge block 503 to reset. The arc protrusions of the flexible plate 508 squeeze each other, squeezing out the gravel in the gap between the plates, ensuring the continuous protection capability of the device.
