Description

Technical Field

[0001] The present invention relates to the technical field of underground scrapers, and in particular to a power output structure of an underground scraper based on dual energy sources. Background Art

[0002] An underground shovel loader is a type of mechanical equipment specially used for loading, transporting and unloading operations in narrow spaces such as underground mines and tunnels. Underground shovel loaders can be divided into internal combustion shovel loaders and electric shovel loaders. Internal combustion shovel loaders use internal combustion engines as their power source, have strong power and good fuel economy, and are suitable for underground environments with relatively good ventilation conditions; electric shovel loaders are powered by electricity and have the advantages of no pollution, zero emissions and low cost. Their working principle is that the driver drives the shovel loader to the material to be loaded, lowers the bucket, inserts the shovel blade into the material pile, and controls the bucket to be filled with materials by operating the hydraulic system, and transports the filled materials to the designated location. Due to the special working point of the underground shovel loader, the shovel loader needs to be smaller than the conventional shovel loader so that the shovel loader can be driven through narrow roads to the underground where shoveling is required, which makes the underground shovel loader transport less materials at the same time.

[0003] The existing scraper uses a single hydraulic system to control the bucket to fill the material. Although it can transport and move the material, it still has the following problems. The existing scraper uses the hydraulic system to insert the bucket into the material for filling. However, in this process, the hydraulic system needs to control the bucket through components such as pins and connecting rods, which is equivalent to inserting the bucket into the material through the torque and thrust of the connecting rod. If the scraper is filling hard materials (stones), the torque of the connecting rod is difficult to insert into the gap of the material, or a higher power output is required to complete the operation. When the bucket is controlled by the pin and connecting rod, the relative position between the bucket and the boom and other components will be affected. Due to the positional relationship, it is difficult to accurately control the insertion depth of the bucket during the shoveling process. If the insertion is too shallow, the bucket cannot be filled and the shoveling action needs to be repeated many times. If the insertion is too deep, it may cause the bucket to be overloaded, increase the load and energy consumption of the equipment, and even damage the equipment. In either case, the shoveling efficiency will be reduced. Therefore, an underground shovel loader power output structure is designed, and the output hydraulic cylinder is set to separately control the loading of the bucket. The staff can accurately control the depth of the bucket's shoveling into the material through the output hydraulic cylinder. At the same time, the bucket vibrates during the process of inserting into the material, making it easier for the bucket to cut into the material pile. Summary of the invention

[0004] In view of the problems in the prior art that the single hydraulic system controls the bucket to fill materials, which has low control power and is difficult to insert into the hard material pile, and the workers have difficulty controlling the depth of the bucket, a power output structure for underground shovel loader based on dual energy is proposed.

[0005] The present application provides a dual-energy-based power output structure for an underground shovel loader, the purpose of which is to: control the bucket's cutting into materials by setting a separate output hydraulic cylinder, so that the staff can accurately control the depth of the bucket's cutting, and at the same time, by setting a shoveling component, the bucket is constantly shaking in the process of cutting into materials, and the shaking bucket can fill the material more efficiently and easily. At the same time, in the process of the bucket cutting into materials, the extension steel plate is extended outward through the extension component, thereby improving the bucket's single filling efficiency and effectively improving the working efficiency of the underground shovel loader.

[0006] The technical solution of the present invention is: a power output structure of an underground scraper based on dual energy, comprising a vehicle body, a power box and a bucket, and also comprising an output unit arranged on the side wall of the power box, wherein the output unit comprises a shoveling component and an extension component arranged on the side wall of the power box;

[0007] The shoveling component includes a mounting groove provided inside the power box, a plurality of output hydraulic cylinders provided inside the mounting groove, a connecting plate provided at the telescopic ends of the plurality of output hydraulic cylinders, a bucket provided on the side wall of the connecting plate, a square groove provided on the side wall of the connecting plate away from the bucket, connecting rods provided at both ends of the side wall of the square groove, two limit plates provided on the side walls on both sides of the power box, limit grooves provided on the limit plates, a concave-convex plate provided in the limit grooves, trigger wheels provided on the side walls on both sides of the bucket, and matching protrusions provided at the lower ends of the two trigger wheels;

[0008] The telescopic ends of the multiple output hydraulic cylinders are fixedly mounted on the connecting rod, the two trigger wheels are respectively located in the corresponding limit grooves, the two matching protrusions are located on the corresponding concave-convex plates, the connecting rod is rotatably mounted on the side wall of the square groove, and a driving assembly is installed between the power box and the vehicle body.

[0009] Furthermore, the extension component includes a sliding groove opened inside the lower part of the bucket, sliding seats arranged on both sides of the sliding groove, an extension steel plate slidably arranged between the two sliding seats, a shovel blade arranged on the side wall of the extension steel plate, and sliding tooth plates slidably arranged inside the two sliding seats respectively, a control component is installed between the sliding tooth plate and the power box, and a transmission component is installed between the sliding tooth plate and the extension steel plate.

[0010] Furthermore, the driving assembly includes a control shell arranged on the vehicle body, two driving hydraulic cylinders 1 arranged on the upper end of the control shell, a driving arm arranged between the telescopic ends of the two driving hydraulic cylinders 1, a connector arranged between the two driving arms, a driving hydraulic cylinder 2 arranged on the connector, and a hinged plate arranged on the upper end of the power box, and the end of the connector away from the driving hydraulic cylinder 2 is hingedly mounted on the hinged plate.

[0011] Furthermore, the control component includes a mounting seat 1 arranged on the side wall of the power box, a mounting seat 2 arranged on the side wall of the sliding tooth plate, a connecting rod 1 hingedly arranged on the mounting seat 1, and a connecting rod 2 hingedly arranged on the mounting seat 2, and one end of the connecting rod 1 is hinged to one end of the connecting rod 2.

[0012] Furthermore, the transmission assembly includes two transmission shafts 1 and 2 arranged on the bottom wall of the sliding groove, two driving gears respectively arranged on the two transmission shafts 1, two driven gears respectively arranged on the two transmission shafts 2, a transmission belt arranged between the corresponding transmission shafts 1 and 2, and racks arranged on the side walls on both sides of the extended steel plate, the two driving gears are respectively meshed with the corresponding sliding tooth plates, and the two driven gears are respectively meshed with the corresponding racks.

[0013] Furthermore, rotating rods are rotatably installed on both sides of the rear side of the vehicle body, and a control motor is fixedly installed inside the vehicle body. The driving end of the control motor is fixedly connected to one end of the rotating rod. A bias rod is fixedly installed on the two rotating rods, and a support plate is installed between the two bias rods.

[0014] Furthermore, the support plate is provided with an oblique angle, and a rubber pad is sleeved and installed at the oblique angle of the support plate.

[0015] Furthermore, an elastic rope net is installed between the upper end of the bucket and the side walls on both sides of the extended steel plate to prevent materials from falling.

[0016] Beneficial effects of the present invention:

[0017] By setting up the shoveling parts, the bucket will continue to shake when cutting into the material (especially hard materials, such as stone piles). The shaking can make it easier for the bucket to cut into the material pile, reduce the friction between the material and the bucket and the cohesion inside the material, and enable the bucket to be inserted into the material more quickly and smoothly, thereby shoveling more material per unit time and improving work efficiency. For example, in underground mining, when facing a pile of ore with a higher hardness, the shaking bucket can easily cut in and complete the shoveling operation faster than an ordinary bucket. When the scraper needs to unload, the output hydraulic cylinder is controlled to recover. At this time, the bucket will also shake. The shaking bucket can unload the internal material faster, effectively improving the work efficiency of the scraper.

[0018] By setting an extension component, when the bucket is cutting into the material pile, the extension steel plate inside the bucket sliding groove will extend outward. The extended extension steel plate can increase the volume of the bucket, so that the bucket can transport more materials during a single transportation process, effectively improving the working efficiency of the bucket. When the bucket is not working, the extension steel plate is located inside the bucket, which can reduce the volume of the bucket and facilitate the transportation and movement of the scraper.

[0019] By setting up a separate output hydraulic cylinder to control the shoveling of the bucket, the staff can more accurately control the depth of the bucket's penetration into the material pile through the output hydraulic cylinder, effectively avoiding the need for multiple shoveling actions due to shallow insertion depth, or increased equipment load and energy consumption due to excessive insertion. By improving the power output structure of the scraper, the scraper's working efficiency is improved while its service life is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figure 1-Figure 7 , which is the first embodiment of the present invention, provides a power output structure of an underground scraper based on dual energy, including a vehicle body 1, a power box 2 and a bucket 3, and also includes an output unit installed on the side wall of the power box 2, and the output unit includes a shoveling component and an extension component installed on the side wall of the power box 2.

[0034] The shoveling components include a mounting groove 4 provided inside the power box 2, a plurality of output hydraulic cylinders 5 fixedly installed inside the mounting groove 4, a connecting plate 6 fixedly installed on the side wall of the bucket 3, a square groove 7 provided on the side wall of the connecting plate 6 away from the bucket 3, a connecting rod 8 rotatably installed at both ends of the side wall of the square groove 7, two limit plates 9 respectively fixedly installed on the side walls on both sides of the power box 2, a limit groove 10 provided on the limit plate 9, a concave-convex plate 11 fixedly installed in the limit groove 10, trigger wheels 12 respectively fixedly installed on the side walls on both sides of the bucket 3, and matching protrusions 13 respectively fixedly installed at the lower ends of the two trigger wheels 12.

[0035] The telescopic ends of multiple output hydraulic cylinders 5 are fixedly mounted on the connecting rod 8, the two trigger wheels 12 are respectively located in the corresponding limit grooves 10, the two matching protrusions 13 are both located on the corresponding concave-convex plates 11, the connecting rod 8 is rotatably mounted on the side wall of the square groove 7, and a driving assembly is installed between the power box 2 and the vehicle body 1.

[0036] Specifically, by setting the output hydraulic cylinder 5 to independently control the bucket 3 to cut into the material, the staff can accurately control the depth of the bucket 3 cutting into the material by controlling the length of the output hydraulic cylinder 5, avoiding the situation where the bucket 3 cuts into the material at a shallow depth and requires multiple shoveling actions, or inserts the material at a deep depth, which increases the load and energy consumption of the equipment. The bucket 3 is connected to the telescopic end of the output hydraulic cylinder 5 through the connecting rod 8. This connection method can ensure that the telescopic end of the output hydraulic cylinder 5 can drive the bucket 3 to move synchronously, and does not limit the bucket 3 to move in the vertical direction of the movement, providing a basis for subsequent vibration. At the same time, by setting the concave-convex plate 11 on the limit plate 9 and fixing the trigger wheel 12 on the side wall of the bucket 3, when the bucket 3 moves synchronously along the direction of the output hydraulic cylinder 5, the matching protrusion 13 on the trigger wheel 12 can cooperate with the concave-convex plate 11, so that the bucket 3 can continuously shake while cutting into the material. Thereby, the bucket 3 is always in a shaking state while cutting into the material under the action of the output hydraulic cylinder 5, and the bucket 3 in the shaking state can cut into the inside of the material more easily because: the vibrating bucket 3 can reduce the friction between the material and the bucket 3 and the cohesion inside the material, so that the bucket 3 can be inserted into the material more quickly and smoothly, thereby shoveling more material per unit time and improving work efficiency. At the same time, the vibration can cause relative movement between material particles, breaking the stacking structure of the material and making the material loose, thereby reducing the resistance that the bucket 3 needs to overcome when digging, which means that the equipment can complete the shoveling work with less power consumption, reducing the load on the equipment, reducing energy consumption, and also reducing the wear of components such as the engine, thereby extending the service life of the equipment.

[0037] The bucket 3 is made to vibrate during the synchronous horizontal movement following the telescopic end of the output hydraulic cylinder 5, which not only effectively improves the loading efficiency of the bucket 3, but also improves the unloading efficiency of the bucket 3. When the scraper runs to the point where unloading is required, the telescopic end of the output hydraulic cylinder 5 begins to reset. During the resetting process, the trigger wheel 12 on the bucket 3 will synchronously reset along the concave-convex plate 11 with the matching protrusion 13. When the matching protrusion 13 moves along the path on the concave-convex plate 11, it will also bring the bucket 3 to move vertically up and down along the direction of movement to vibrate. A normal bucket When feeding, hard materials (rock piles) may squeeze and get stuck with each other, resulting in unsmooth feeding or even blocking bucket 3. The vibrating bucket 3 can destroy the interaction and stacking structure between the stones, making it difficult for the stones to form a stable blocking state, allowing the stones to flow out of bucket 3 more smoothly, ensuring the continuity of the feeding process. At the same time, vibration can make the stones more evenly distributed, avoiding excessive or insufficient local accumulation, so that the stones can fall from bucket 3 at a relatively stable flow rate and speed, improving the stability and accuracy of the entire process. The vibrating bucket 3 can also improve the feeding efficiency. Vibration can enable the stones to overcome the friction between the bucket 3 and the friction between the stones, accelerate the sliding speed of the stones, thereby shortening the feeding time, increasing the feeding amount per unit time, and improving work efficiency.

[0038] Reference Figure 1-Figure 3 The driving assembly includes a control housing 19 fixedly mounted on the vehicle body 1, two driving hydraulic cylinders 20 fixedly mounted on the upper end of the control housing 19, a driving arm 21 hingedly mounted between the telescopic ends of the two driving hydraulic cylinders 20, a connector 22 hingedly mounted between the two driving arms 21, a driving hydraulic cylinder 23 fixedly mounted on the connector 22, and a hinged plate 24 fixedly mounted on the upper end of the power box 2, and one end of the connector 22 away from the driving hydraulic cylinder 23 is hingedly mounted on the hinged plate 24.

[0039] Specifically, the driving hydraulic cylinder 1 20 and the driving hydraulic cylinder 2 23 are used to control the position and direction of the bucket 3. The conventional scraper controls the driving arm 21 through the driving hydraulic cylinder 1 20 and the driving hydraulic cylinder 2 23, so that the torque of the driving arm 21 and its own thrust are used to control the bucket 3 to cut into the material. However, in this way, it is difficult for the staff to control the depth of the bucket 3 cutting into the material, and the driving arm 21 and its connection points are worn out. At the same time, the force generated cannot fully act on the bucket 3 cutting into the material, which will cause overload or damage to the power source. Therefore, the driving hydraulic cylinder 1 20 and the driving hydraulic cylinder 2 23 in the present invention are only used to control the angle and position of the bucket 3, and the output hydraulic cylinder 5 is used to control the bucket 3 to load and unload the material.

[0040] Example 2, reference Figure 8-Figure 10, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the extension component includes a sliding groove 14 opened inside the lower part of the bucket 3, a sliding seat 15 fixedly installed on both sides of the sliding groove 14, an extension steel plate 16 slidably installed between the two sliding seats 15, a shovel blade 17 fixedly installed on the side wall of the extension steel plate 16, and sliding tooth plates 18 slidably installed inside the two sliding seats 15, respectively, a control component is installed between the sliding tooth plate 18 and the power box 2, and a transmission component is installed between the sliding tooth plate 18 and the extension steel plate 16. The control component includes a mounting seat 1 25 fixedly installed on the side wall of the power box 2, a mounting seat 2 26 fixedly installed on the side wall of the sliding tooth plate 18, a connecting rod 1 27 hingedly installed on the mounting seat 1 25, and a connecting rod 2 28 hingedly installed on the mounting seat 2 26, and one end of the connecting rod 1 27 is hinged to one end of the connecting rod 2 28. The transmission assembly includes two transmission shafts 1 29 and 2 30 rotatably mounted on the bottom wall of the sliding groove 14, two driving gears 31 fixedly mounted on the two transmission shafts 1 29, two driven gears 32 fixedly mounted on the two transmission shafts 2 30, a transmission belt 33 sleeved between the corresponding transmission shafts 1 29 and 2 30, and racks 34 fixedly mounted on the side walls of the extension steel plate 16. The two driving gears 31 are respectively meshed with the corresponding sliding toothed plates 18, and the two driven gears 32 are respectively meshed with the corresponding racks 34. An elastic rope net 38 is installed between the upper end of the bucket 3 and the side walls of the extension steel plate 16 to prevent materials from falling.

[0041] Specifically, the function of the extension component is: through the process of the bucket 3 following the synchronous movement of the telescopic end of the output hydraulic cylinder 5, the extension steel plate 16 inside the bucket 3 is extended outward during the movement, which is used to increase the volume of the bucket 3, increase the amount of materials that the bucket 3 can shovel at a time, and improve the working efficiency of the scraper. The elastic rope net 38 is used to protect both sides of the extended extension steel plate 16 to prevent the materials on the extension steel plate 16 from falling off in the bumpy conditions during transportation after the scraper is loaded, resulting in safety accidents. The elastic rope net 38 is elastic, ensuring that the extension steel plate 16 can be extended normally. At the same time, the elastic rope net 38 always protects both sides of the extension steel plate 16. It should be noted that during the sliding process of the sliding tooth plate 18, one end of the connecting rod 28 is always located inside the sliding seat 15, which is convenient for the subsequent resetting of the sliding tooth plate 18.

[0042] When the bucket 3 cuts into the material under the action of the output hydraulic cylinder 5, the bucket 3 moves horizontally relative to the power box 2. At this time, the power box 2 generates a pulling force on the sliding tooth plate 18 through the connecting rod 1 27 and the connecting rod 2 28, so that the sliding tooth plate 18 slides in the sliding seat 15. During the sliding process of the sliding tooth plate 18, the driving gear 31 is driven to rotate, and then the corresponding driven gear 32 is driven to rotate synchronously through the transmission belt 33. The rotation of the driven gear 32 will drive the corresponding rack 34 to move in the opposite direction along the sliding seat 15 relative to the sliding tooth plate 18, so that the rack 34 drives the extension steel plate 16 to move synchronously, and the extension steel plate 16 extends outward, thereby increasing the overall capacity of the bucket 3 and improving the working efficiency of the scraper loader.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3, reference Figure 1-Figure 2 , which is the third embodiment of the present invention, is different from the second embodiment in that: a rotating rod 35 is rotatably installed on both sides of the rear side of the vehicle body 1, a control motor (not shown) is fixedly installed inside the vehicle body 1, the driving end of the control motor is fixedly connected to one end of the rotating rod 35, and a deflection rod 36 is fixedly installed on the two rotating rods 35, and a support plate 37 is installed between the two deflection rods 36. The support plate 37 is provided with an oblique angle, and a rubber pad is sleeved and installed at the oblique angle of the support plate 37.

[0045] Specifically, the support plate 37 is located at the rear of the vehicle body 1 and is used to support the vehicle body 1 when loading. When the bucket 3 cuts into the material, the bucket 3 will generate a reverse force on the vehicle body 1. If there is no support plate 37, the reverse force will act completely on the vehicle body 1. At this time, the vehicle body 1 needs to increase the engine power to overcome this force. Therefore, by setting the support plate 37, when the bucket 3 is loading, the support plate 37 can support the vehicle body 1 to offset the reverse force on the vehicle body 1, thereby improving the overall stability of the shovel loader during loading.

[0046] The remaining structure is the same as that of Example 2.

[0047] Based on Examples 1-3, the working principle of the present invention is as follows: when the shovel loader needs to load materials in the underground tunnel, the staff drives the shovel loader to the material pile, adjusts the position of the bucket 3 by driving the hydraulic cylinder 1 20 and the hydraulic cylinder 2 23, and then turns on the control motor, so that the control motor drives the deflection rod 36 on the rotating rod 35 to deflect through the driving end. During the deflection process, the deflection rod 36 puts the oblique angle of the support plate 37 close to the ground, so as to support the vehicle body 1 during subsequent loading.

[0048] The staff turns on the output hydraulic cylinder 5, and the telescopic end of the output hydraulic cylinder 5 extends out through the connecting rod 8 and the connecting plate 6 to drive the bucket 3 to move synchronously, so that the bucket 3 cuts into the material along with the telescopic end of the output hydraulic cylinder 5. In the process of synchronous movement of the bucket 3 along the telescopic end, the trigger wheels 12 on both sides move along the path on the concave-convex plate 11 through the matching protrusions 13 at the lower ends. Because the concave-convex plate 11 is provided with a plurality of concave-convex points, the trigger wheels 12 cooperate with the matching protrusions 13 and the concave-convex plate 11 to drive the bucket 3 to continuously move up and down in the vertical direction of the movement, thereby realizing that the bucket 3 continuously vibrates in the process of cutting into the material, so that the bucket 3 can better cut into the material and fill the material into the bucket 3.

[0049] When the bucket 3 cuts into the material under the action of the output hydraulic cylinder 5, the bucket 3 moves horizontally relative to the power box 2. At this time, the power box 2 generates a pulling force on the sliding tooth plate 18 through the connecting rod 1 27 and the connecting rod 2 28, so that the sliding tooth plate 18 slides in the sliding seat 15. During the sliding process of the sliding tooth plate 18, the driving gear 31 is driven to rotate, and then the corresponding driven gear 32 is driven to rotate synchronously through the transmission belt 33. The rotation of the driven gear 32 will drive the corresponding rack 34 to move in the opposite direction along the sliding seat 15 relative to the sliding tooth plate 18, so that the rack 34 drives the extension steel plate 16 to move synchronously, and the extension steel plate 16 extends outward, thereby increasing the overall capacity of the bucket 3. At the same time, when the extension steel plate 16 extends outward, the elastic rope nets 38 on both sides thereof are continuously stretched, and the two sides of the extension steel plate 16 are protected to prevent the bumps of the scraper during the movement from causing the material to fall and cause safety hazards.

[0050] When the scraper arrives at the designated position, the staff controls the output hydraulic cylinder 5 to reset its telescopic end. During the resetting process of the output hydraulic cylinder 5, the sliding tooth plate 18 is reset synchronously, and then the extension steel plate 16 is driven by the transmission belt 33 to reset inward. During the resetting process of the extension steel plate 16, the material on the upper end is unloaded. At the same time, while the bucket 3 follows the output hydraulic cylinder 5 to reset, the trigger wheel 12 cooperates with the concave-convex plate 11 again, causing the bucket 3 to vibrate. The vibrating bucket 3 can unload the internal material faster.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
