Description

Technical Field

[0001] This utility model relates to the field of open-pit coal mine engineering technology, and in particular to an open-pit coal mine safety retaining wall forming device. Background Technology

[0002] The existing open-pit mine safety retaining wall forming machine includes a frame, hydraulic system and power source. Its special feature is that it also includes a material forming mechanism set on the front side of the frame, which is used to realize the material collection and forming of the retaining wall, and the material collection and forming work synchronously and in parallel; a forming and calendering mechanism set on the rear side of the frame, which is used to perform forming and calendering operations on the formed retaining wall; and an automatic walking mechanism set on the side and bottom of the forming and calendering mechanism, which is used to realize the automatic walking of the entire device along the retaining wall and the ground. This open-pit mine safety retaining wall forming machine has the following technical problems: (1) Complex operation: The equipment operation interface is not intuitive enough, the control system design is relatively complicated, and the operators need to undergo a long period of training to master it. In addition, the equipment needs to frequently adjust various parameters during operation, which requires high skills from the operators, which to some extent limits the efficiency of the equipment and its promotion and application. (2) Safety hazards: Safety hazards are also an issue that cannot be ignored by the existing forming device. Although the equipment is equipped with a basic safety system, there are still potential risks such as accidental detachment of mechanical parts, oil leakage of the hydraulic system and short circuit of the electrical system during actual operation. These safety hazards not only threaten the lives of operators, but may also lead to equipment damage and production interruption. (3) Insufficient production capacity: Insufficient production capacity is another major problem faced by existing molding equipment. Under high-intensity operating conditions, the equipment often cannot maintain stable production efficiency for a long time. On the one hand, the molding speed is slow and cannot meet the high-efficiency production needs of large open-pit mines; on the other hand, the equipment is prone to overheating and wear during continuous operation, which further affects production efficiency and finished product quality. (4) High maintenance costs: Due to the complex structure and numerous parts of the equipment, the daily maintenance and repair work is large, time-consuming and labor-intensive, and frequent replacement of vulnerable parts is required, resulting in high maintenance costs. Especially in remote mining areas, equipment maintenance faces challenges such as difficulty in purchasing spare parts and a shortage of technical personnel, which increases the operating burden of enterprises. (5) Lagging technology updates: Lagging technology updates make it difficult for existing molding equipment to adapt to the rapidly developing mining needs. With the continuous progress of open-pit mining technology, the market has put forward higher requirements for the automation and intelligence level of molding equipment. However, the existing equipment technology updates are slow and cannot introduce advanced technology in a timely manner, resulting in the equipment gradually falling behind industry needs in terms of performance, efficiency and safety. Utility Model Content

[0003] The purpose of this utility model is to solve at least one technical problem in the background art and to provide a device for forming a safety retaining wall in an open-pit coal mine.

[0004] To achieve the above objectives, this utility model provides a safety retaining wall forming device for open-pit coal mines, comprising:

[0005] Support plate;

[0006] A scraper, movably supported on one surface of the support plate, is used to scrape and shape the soil for safety retaining walls in open-pit coal mines.

[0007] The drive structure is supported on the other surface of the support plate, and its output end passes through the support plate and is connected to the scraper blade, thereby driving the scraper blade to adjust its angle.

[0008] A fixed structure is used to fix the relative position of the scraper blade and the support plate after the scraper blade is adjusted to an angle.

[0009] According to one aspect of the present invention, the support plate is a right-angled triangular plate, and the scraping edge of the scraping plate is arranged opposite to the hypotenuse of the support plate. Driven by the driving structure, the scraping edge aligns with or intersects the hypotenuse to form an angle.

[0010] According to one aspect of the present invention, the driving structure is disposed at the bottom acute angle of the support plate, and its output end passes through the support plate and is connected to the bottom of the scraper.

[0011] According to one aspect of the present invention, the drive structure includes a drive worm, a worm wheel, and an output shaft;

[0012] The drive worm and the worm wheel are disposed on the surface of the support plate opposite to the scraper plate;

[0013] The output shaft is concentrically arranged with the worm gear, and the output shaft passes through the support plate and is fixedly connected to the scraper blade.

[0014] According to one aspect of the present invention, the support plate is provided with a plurality of spaced first pin holes, and the scraper plate is provided with a plurality of spaced second pin holes. After the scraper plate is rotated and its angle adjusted by the driving structure, the support plate and the scraper plate are fixed relative to each other by the fixing structure passing through the corresponding first pin holes and second pin holes.

[0015] According to one aspect of the present invention, the fixing structure is a fixing pin.

[0016] According to the present invention, this invention utilizes two scraper blades and a worm gear mechanism. The front scraper blade is the main scraper blade, and the rear support plate is the secondary support plate. The angle of the scraper blade can be adjusted by a hydraulic motor driven by the worm gear mechanism on the support plate. After adjustment, the holes on the support plate and the scraper blade can be fixed with pins to increase the fixing strength. The worm gear mechanism is chosen because it has a self-locking function, working together with the pins to provide better fixing, and it allows for arbitrary changes in the angle of the scraper blade. This design offers greater applicability; the overall device can be adjusted in size according to different equipment and installed on wheeled bulldozers, tracked bulldozers, or front-mounted loaders. Furthermore, the structural design of this device emphasizes simplification and practicality, minimizing unnecessary complex parts to make the overall structure more compact and stable. This design philosophy not only makes the device more efficient in function but also significantly improves its service life and reliability. Through simplified design, the various components of the device are more coordinated, reducing maintenance problems caused by wear or failure of parts, thereby improving the long-term stability and durability of the device. This structural optimization also reduces the difficulty and cost of maintenance and repair, making routine maintenance simpler and more economical. Furthermore, the simplified structure means a significant reduction in the weight of the device, an advantage particularly important in practical applications. The reduced weight allows the device to better adapt to the load capacity of the pre-installed equipment, reducing the requirements for mobility and stability. This not only improves the safety of the device during construction but also enhances its adaptability to various terrains and working environments. By reducing the overall weight of the device, operational flexibility is improved, the burden on mechanical equipment is reduced, and its service life is extended.

[0017] According to the present invention, the scraper blade can be adjusted in angle and direction via a worm gear mechanism on the support plate to meet the needs of different working conditions. The worm gear mechanism is a key component of this invention. This mechanism was chosen because it has a self-locking function, maintaining stability without external force, thus providing better fixation together with the fixing pin. This self-locking function not only increases the stability of the scraper blade but also makes the angle adjustment more precise and reliable, avoiding loosening caused by vibration or impact. The holes on the support plate and scraper blade are rationally designed, allowing for fixation with the fixing pin, thereby increasing the fixing strength. The use of the pin simplifies the installation and disassembly process and improves the durability and safety of the entire device. Through the cooperation of the worm gear mechanism and the fixing pin, the angle of the scraper blade can be adjusted arbitrarily, offering greater adaptability and meeting the needs of different terrains and working environments.

[0018] The solution of this utility model has wider applicability, and the angle can be adjusted according to the requirements of different mine spoil heaps. The structure is simpler, facilitating later installation and maintenance, and reducing labor costs and construction risks. Work efficiency is higher; the worm gear device provides more precise angle adjustment, ensuring that each spoil heap is manufactured to meet design requirements. Costs are saved; it can be installed on existing open-pit mining equipment and is easy to assemble and disassemble. It possesses high mobility and flexibility, enabling rapid adaptation to constantly changing underground environments. The spoil heap (safety retaining wall) is formed faster, stronger, and more robust, and adaptable to various rock and soil surfaces. Attached Figure Description

[0021] The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the described embodiments are merely intended to enable those skilled in the art to better understand and thus implement the present invention, and are not intended to imply any limitation on the scope of the present invention.

[0022] As used herein, the term "comprising" and its variations are to be interpreted as open-ended terms meaning "including but not limited to". The term "based on" is to be interpreted as "at least partially based on". The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment".

[0023] Figure 1 This schematic diagram shows a front view of an open-pit coal mine safety retaining wall forming device according to one embodiment of the present invention. Figure 2 This schematic diagram shows a rear view of an open-pit coal mine safety retaining wall forming device according to one embodiment of the present invention. Figure 1 and Figure 2 As shown, in this embodiment, the open-pit coal mine safety retaining wall forming device includes:

[0024] Support plate 1;

[0025] The scraper 2 is movably supported on one surface of the support plate 1 and is used to scrape and shape the safety retaining wall in the open-pit coal mine.

[0026] The drive structure 3 is supported on the other surface of the support plate 2, and its output end passes through the support plate 2 and is connected to the scraper 2, thereby driving the scraper 2 to adjust its angle.

[0027] A fixed structure is used to fix the relative position of the scraper blade 2 and the support plate 1 after the scraper blade 2 is adjusted at its angle. This configuration allows the scraper blade 2 to be driven and rotated by the drive structure 3 to adjust its angle, enabling it to scrape and shape the soil and rock on the open-pit coal mine surface at a corresponding angle, forming a slope and creating a safety retaining wall. Specifically, when using this open-pit coal mine safety retaining wall forming device, the device is first installed on the side wall of, for example, the bucket of a bulldozer through the mounting port 9 on the back of the support plate 2, so that the device extends towards the side of the bulldozer. As the bulldozer moves forward, the device scrapes and pushes the soil and rock on the side into a safety retaining wall with a corresponding slope (inclination) or combination of slopes, in conjunction with the scraper blade and support plate. This safety retaining wall encloses the open-pit coal mine mining area, improving the area's safety.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the support plate 1 is a right-angled triangle, and the scraping edge of the scraper 2 is positioned opposite to the hypotenuse of the support plate 1. Driven by the drive structure 3, the scraping edge aligns with or intersects the hypotenuse to form an angle. This arrangement allows for the formation of various angles or combinations of angles through the cooperation of the support plate 1 and the scraper 2, resulting in a safety retaining wall with multiple angles to meet different site requirements.

[0029] Furthermore, such as Figure 1 As shown, in this embodiment, the drive structure 3 is located at the bottom acute angle of the support plate 1, and its output end passes through the support plate 1 and connects to the bottom of the scraper plate 2. This arrangement allows the scraper plate 2 to be driven to rotate as a whole from the end via the drive structure 3, resulting in a larger rotation angle and range, more precise forming slope, and smaller errors.

[0030] Furthermore, such as Figure 1 As shown, in this embodiment, the drive structure 3 includes a drive worm 4, a worm wheel 5, and an output shaft 6;

[0031] The drive worm 4 and worm wheel 5 are mounted on the surface of the support plate 1 opposite to the scraper plate 2;

[0032] The output shaft 6 is concentrically positioned with the worm gear 5, and the output shaft passes through the support plate 1 and is fixedly connected to the scraper blade 2. This configuration allows the angle of the scraper blade 2 to be controlled and adjusted via the worm gear mechanism. Furthermore, the worm gear mechanism has a self-locking function, which can lock the angle after adjustment to ensure stability.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the support plate 1 has multiple spaced-apart first pin holes 7, and the scraper plate 2 has multiple spaced-apart second pin holes 8. After the scraper plate 2 is rotated and its angle adjusted by the drive structure 3, the support plate 1 and the scraper plate 2 are fixed relative to each other by a fixing structure passing through the corresponding first pin holes 7 and second pin holes 8. The fixing structure is a fixing pin. This arrangement allows the angle of the scraper plate 2 relative to the support plate 1 to be fixed by the fixing pin, ensuring that the scraper plate 2 is stable and reliable during the soil scraping and shaping process.

[0034] According to the above-described solution of this utility model, it is implemented using two scraper blades and a worm gear mechanism. The front is a scraper blade, and the rear is a support plate. The scraper blade's angle can be adjusted by a hydraulic motor driven by the worm gear mechanism on the support plate. After adjustment, the holes on the support plate and scraper blade can be fixed with pins to increase the fixing strength. The worm gear mechanism is chosen because it has a self-locking function, which, together with the pins, provides better fixing, and the angle of the scraper blade can be changed arbitrarily. It has higher applicability; the overall device can be adjusted in size according to different equipment and installed on wheeled bulldozers, tracked bulldozers, or front-mounted loaders. Furthermore, the structural design of this device emphasizes simplification and practicality, minimizing unnecessary complex parts to make the overall structure more compact and stable. This design concept not only makes the device more efficient in function but also significantly improves its service life and reliability. Through simplified design, the various components of the device are more coordinated, reducing maintenance problems caused by wear or failure of parts, thereby improving the long-term stability and durability of the device. This structural optimization also reduces the difficulty and cost of maintenance and repair, making routine maintenance simpler and more economical. Furthermore, the simplified structure means a significant reduction in the weight of the device, an advantage particularly important in practical applications. The reduced weight allows the device to better adapt to the load capacity of the pre-installed equipment, reducing the requirements for mobility and stability. This not only improves the safety of the device during construction but also enhances its adaptability to various terrains and working environments. By reducing the overall weight of the device, operational flexibility is improved, the burden on mechanical equipment is reduced, and its service life is extended.

[0035] According to the above-described solution of this utility model, the scraper blade can be adjusted in angle and direction via a worm gear mechanism on the support plate to meet the needs of different working conditions. The worm gear mechanism is a key component of this utility model. This mechanism was chosen because it has a self-locking function, maintaining stability without external force, thus providing better fixation together with the fixing pin. This self-locking function not only increases the stability of the scraper blade but also makes the angle adjustment more precise and reliable, avoiding loosening caused by vibration or impact. The holes on the support plate and scraper blade are rationally designed, allowing for fixation with fixing pins, thereby increasing the fixing strength. The use of pins not only simplifies the installation and disassembly process but also improves the durability and safety of the entire device. Through the cooperation of the worm gear mechanism and the fixing pin, the angle of the scraper blade can be adjusted arbitrarily, offering greater adaptability and meeting the needs of different terrains and working environments.

[0036] According to the above-described solution of this utility model, its applicability is wider, and the angle can be adjusted according to the requirements of different mine spoil heaps. The structure is simpler, facilitating later installation and maintenance, and reducing labor costs and construction risks. Work efficiency is higher; the worm gear device provides more precise angle adjustment, ensuring that the fabrication of each spoil heap piece meets design requirements. Cost-effective, it can be installed on existing open-pit mining equipment and is easy to assemble and disassemble. It possesses high mobility and flexibility, enabling rapid adaptation to constantly changing underground environments. The spoil heap (safety retaining wall) is formed faster, stronger, and more robust, and adaptable to various rock and soil surfaces.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
