Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, and in particular to a crushing mechanism assembly and a trolley with the crushing mechanism assembly. Background Technology

[0002] In the existing technology, the crushing mechanism assembly hinges the breaker hammer to the robotic arm assembly at a certain angle. However, this method results in a long crushing mechanism assembly and limits the crushing mechanism assembly to a small area of ​​vertical crushing at the working face. If full vertical crushing of the working face is required, the vehicle carrying the crushing mechanism assembly needs to be moved constantly, which is not conducive to improving the crushing efficiency at the working face and has room for improvement. Utility Model Content

[0003] In view of this, this application provides a crushing mechanism assembly and a trolley with the crushing mechanism assembly. The crushed parts are mounted on a rotary mechanism via a rotary table with corners, so that the position of the crushed parts can be quickly adjusted by rotating the rotary assembly, thereby enabling the crushed parts to have a large range of vertical crushing. Furthermore, through the coordinated cooperation of the swing mechanism and the second rotary mechanism, the range of vertical crushing of the crushed parts on the working face is further expanded. At the same time, the crushed parts can be deeply crushed on uneven working faces by the propulsion cylinder. In addition, the overall layout of the trolley is optimized by the structure of the crushing mechanism assembly and the position of the crushing mechanism assembly on the trolley.

[0004] In summary, in order to expand the range of vertical crushing that the crushing mechanism assembly can perform at the working face and improve the crushing efficiency of the crushing mechanism assembly, this application proposes a crushing mechanism assembly and a trolley with the crushing mechanism assembly.

[0005] The crushing mechanism assembly provided in this application adopts the following technical solution:

[0006] A crushing mechanism assembly includes a multi-degree-of-freedom robotic arm assembly and a crushing component. The robotic arm assembly includes a first rotary mechanism, a pitch mechanism, a swing mechanism, and a second rotary mechanism. One end of the pitch mechanism is connected to the first rotary mechanism, and the other end is connected to the swing mechanism. One end of the second rotary mechanism is connected to the swing mechanism, and the other end is connected to the crushing component. The second rotary mechanism includes a rotary component and a rotary table. One end of the rotary component is connected to the swing mechanism, and the other end is connected to the rotary table. The rotary table has a corner. The crushing component includes a feed slide, a breaker hammer, and a feed cylinder. The feed slide is connected to the rotary table, the breaker hammer is connected to the feed slide, and one end of the feed cylinder is connected to the feed slide, and the other end is connected to the breaker hammer.

[0007] By adopting the above technical solution, the user can adjust the robotic arm assembly to align the breaker hammer vertically with the working face. The second rotary mechanism causes the breaker hammer to perform circular motion, thereby increasing the area that the breaker hammer can crush vertically on the working face. When the breaker hammer makes the working face uneven, the extension and retraction of the propulsion cylinder allows the breaker hammer to penetrate deeper into the working face for crushing. Deep crushing can be easily completed without the need for the trolley to move, which is beneficial to improving the crushing efficiency of the crushing work. In addition, the robotic arm assembly can also move the propulsion slide in the vertical direction through the pitch mechanism, and move the breaker hammer in the horizontal direction through the first rotary mechanism and the swing mechanism. Through the cooperation of the first rotary mechanism and the swing mechanism, the breaker hammer can maintain its vertical setting on the working face when moving in the horizontal direction. Thus, the crushing mechanism assembly gives the breaker hammer a large range for vertical crushing on the working face.

[0008] Preferably, the pitch mechanism includes a first pitch mechanism and a second pitch mechanism. The first pitch mechanism includes a boom and a first hydraulic cylinder, and the second pitch mechanism includes a middle boom and a second hydraulic cylinder. One end of the boom is connected to the first slewing mechanism, and the other end is connected to the middle boom. The first hydraulic cylinder is symmetrically arranged on both sides of the boom, with one end connected to the boom and the other end connected to the first slewing mechanism. The second hydraulic cylinder is arranged on the middle boom, with one end connected to the middle boom and the other end connected to the boom.

[0009] By adopting the above technical solution, the boom can be rotated vertically by the first hydraulic cylinder, and the middle boom can also be rotated vertically by the second hydraulic cylinder, thereby giving the pitching mechanism a large range of vertical rotation, and thus giving the breaker a large range of vertical crushing on the face of the machine.

[0010] Preferably, the swing mechanism includes a swing seat and a third hydraulic cylinder. The swing seat is connected to one end of the middle arm, and the third hydraulic cylinder is disposed on both sides of the swing seat. One end of the third hydraulic cylinder is connected to the swing seat, and the other end is connected to the middle arm.

[0011] By adopting the above technical solution, the movement of the third oil cylinder drives the swing seat to swing left and right.

[0012] Preferably, the propulsion slide is equipped with a spray assembly.

[0013] By adopting the above technical solution, the working face is sprayed with water, which makes it easier for the hydraulic breaker to break up difficult soil / rock blocks on the working face.

[0014] The trolley with a crushing mechanism assembly provided in this application adopts the following technical solution:

[0015] A trolley with a crushing mechanism assembly includes a chassis assembly, a cab, a protective cover, and the crushing mechanism assembly as described above, wherein the cab is located on the chassis assembly, the protective cover is also located on the chassis assembly, and the crushing mechanism assembly is also located on the chassis assembly.

[0016] By adopting the above technical solution, and based on the fact that the crushing mechanism assembly has a large range for vertical crushing on the working face and a high crushing efficiency, the trolley with the crushing mechanism assembly also has a large range for vertical crushing on the working face and a high crushing efficiency.

[0017] Preferably, the cab is provided with a groove, and the crushing mechanism assembly is at least partially located within the groove.

[0018] By adopting the above technical solution, the overall length of the trolley with the crushing mechanism assembly is effectively shortened.

[0019] Preferably, the cab includes a cab shell, a seat, and a first operating component. The recess is disposed on the outer wall of the lower part of the cab shell, the first operating component is disposed in the cab, and the seat is also located in the cab. The cab also includes an internal hydraulic valve block, which is located inside the seat.

[0020] By adopting the above technical solution and placing the internal hydraulic valve block at the seat, the remaining space of the vehicle can be effectively utilized, thereby reducing the overall vehicle size.

[0021] Preferably, a protrusion is formed in the recess within the cab shell, and the protrusion is provided with a second operating component for controlling the vehicle.

[0022] By adopting the above technical solutions, the space of the entire vehicle can be effectively utilized.

[0023] Preferably, it also includes a leg mechanism, which is inclinedly disposed at the rear end of the rear cover.

[0024] By adopting the above technical solutions, the location of the outrigger structure can be effectively concealed, the space occupied by the outrigger structure can be reduced, and the torque of the outrigger mechanism in supporting the whole vehicle can be optimized.

[0025] Preferably, the outrigger mechanism includes an outrigger assembly and a support. The support is hinged to the lower end of the outrigger assembly. The support includes a base plate, which includes a rocker section and a flat section. The rocker section is connected to both ends of the flat section, and the connection between the rocker section and the flat section is smooth.

[0026] By adopting the above technical solution, compared with traditional vertical telescopic outriggers, this outrigger can better limit the backward horizontal displacement generated when the equipment is working.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The user adjusts the robotic arm assembly to align the breaker hammer vertically with the working face. The second rotary mechanism causes the breaker hammer to move in a circular motion, thereby increasing the area that the breaker hammer can crush vertically on the working face. When the breaker hammer makes the working face uneven, the extension and retraction of the propulsion cylinder allows the breaker hammer to penetrate deeper into the working face for crushing. Deep crushing can be easily completed without the need for the trolley to move, which helps to improve the crushing efficiency of the crushing work. The robotic arm assembly can also move the propulsion slide in the vertical direction through the pitch mechanism, and move the breaker hammer in the horizontal direction through the first rotary mechanism and the swing mechanism. The cooperation of the first rotary mechanism and the swing mechanism allows the breaker hammer to maintain its vertical setting on the working face while moving in the horizontal direction. Thus, the crushing mechanism assembly gives the breaker hammer a large range of vertical crushing on the working face.

[0029] By placing the crushing mechanism assembly in a recess in the cab, the overall length of the trolley with the crushing mechanism assembly is effectively shortened.

[0030] The outrigger mechanism is tilted at the rear of the chassis mechanism, effectively hiding the position of the outrigger structure, reducing the space occupied by the outrigger structure, optimizing the torque of the outrigger mechanism in supporting the whole vehicle, and the rotatable support of the outrigger mechanism is easier to resist protrusions or stones on the bottom surface. Compared with traditional vertical telescopic outriggers, this outrigger can better limit the backward horizontal displacement of the equipment during operation. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. Example

[0041] This application discloses a crushing mechanism assembly.

[0042] Reference Figures 1-3 The system includes a multi-degree-of-freedom robotic arm assembly 1 and a crushing component 2. The robotic arm assembly 1 includes a first rotary mechanism 3, a pitch mechanism 4, a swing mechanism 5, and a second rotary mechanism 6. One end of the pitch mechanism 4 is connected to the first rotary mechanism 3, and the other end is connected to the swing mechanism 5. One end of the second rotary mechanism 6 is connected to the swing mechanism 5, and the other end is connected to the crushing component 2, so that the crushing component 2 is eccentrically positioned on the second rotary mechanism 6.

[0043] The first rotating mechanism 3 is arranged parallel to the horizontal plane, so that the first rotating mechanism 3 can rotate on the horizontal plane. The first hinge seat 36 is symmetrically provided on the upper left side of the first rotating mechanism 3. The first hinge seat 36 is integrally formed with the first rotating mechanism 3. The two second hinge seats 37 are symmetrically provided on both sides of the first hinge seat 36 on the upper left side of the first rotating mechanism 3. The second hinge seats 37 are integrally formed with the first rotating mechanism 3, and the horizontal height of the second hinge seats 37 is lower than that of the first hinge seat 36, and the second hinge seats 37 are tilted to the left.

[0044] The pitch mechanism 4 includes a first pitch mechanism 13 and a second pitch mechanism 14. The first pitch mechanism 13 includes a main arm 15 and a first hydraulic cylinder 16. The second pitch mechanism 14 includes a middle arm 17 and a second hydraulic cylinder 18. The right end of the main arm 15 is hinged to the first hinge seat 36 of the first rotary mechanism 3, and the left end of the main arm 15 is hinged to the lower side of the right end of the middle arm 17. The first hydraulic cylinder 16 is symmetrically arranged on both sides of the main arm 15. One end of the first hydraulic cylinder 16 is hinged to the second hinge seat 37 of the first rotary mechanism 3, and the other end is hinged to the side wall of the main arm 15, so that the extension and retraction of the first hydraulic cylinder 16 drives the main arm 15 to rotate around the first hinge seat 36 of the first rotary mechanism 3. One end of the second hydraulic cylinder 18 is hinged to the upper side of the main arm 15, and the other end is hinged to the upper side of the middle arm 17, so that the extension and retraction of the second hydraulic cylinder 18 drives the middle arm 17 to rotate around its hinge with the main arm 15.

[0045] The swing mechanism 5 includes a swing seat 19 and a third hydraulic cylinder 20. The right end of the swing seat 19 is provided with a third hinge seat 38 for hinged to the middle arm 17. The right end of the swing seat 19 is also provided with a fourth hinge seat 39 on both sides of the third hinge seat 38 for hinged to the third hydraulic cylinder 20. The left end of the middle arm 17 is hinged to the third hinge seat 38 of the swing seat 19. The third hydraulic cylinder 20 is symmetrically arranged on both sides of the middle arm 17, so that one end of the third hydraulic cylinder 20 is hinged to the side wall of the middle arm 17, and the other end is hinged to the fourth hinge seat 39 on the right end of the swing mechanism, so that the third hydraulic cylinder 20 extends and retracts, driving the swing seat 19 to swing left and right at the left end of the middle arm 17.

[0046] The second rotating mechanism 6 includes a rotating component 7 and a rotating table 8. The rotating component 7 is bolted to the swing seat 19. The rotating mechanism includes a power source that drives the rotating component 7 to rotate, allowing the rotating component 7 to rotate in a vertical plane. The rotating table 8 has a corner 9 and is L-shaped. The right end of the rotating table 8 is bolted to the left end of the rotating component 7, so that the rotating table 8 rotates with the rotating component 7. The upper end of the rotating table 8 is bolted to the crushing part 2, so that when the rotating component 7 rotates, the crushing part 2 rotates around the rotating component 7.

[0047] The breaking component 2 includes a push slide 10, a breaker hammer 11, and a push cylinder 12. The front part of the push slide 10 is bolted to the upper end of the rotary table 8, so that the axial direction of the push slide 10 is consistent with the axial direction of the rotary assembly 7, and part of the push slide 10 is located above the rotary assembly 7. The breaker hammer 11 is slidably connected to the push slide 10, and the push cylinder 12 is symmetrically arranged on both sides of the push slide 10. One end of the push cylinder 12 is connected to the push slide 10, and the other end is connected to the breaker hammer 11, so that when the push cylinder 12 extends or retracts, the push cylinder 12 drives the breaker hammer 11 to extend or retract on the push slide 10.

[0048] The user adjusts the robotic arm assembly 1 so that the hydraulic breaker 11 is vertically aligned with the tunnel face. The second rotary mechanism 6 then causes the hydraulic breaker 11 to perform circular motion. This allows the hydraulic breaker 11 to perform vertical crushing of a larger area of ​​the tunnel face with just the rotation of the second rotary mechanism 6, without requiring adjustments to other structures. This not only gives the crushing mechanism assembly 25 a larger range for vertical crushing on the tunnel face but also higher vertical crushing efficiency. When the hydraulic breaker 11 causes unevenness on the tunnel face, the extension and retraction of the hydraulic cylinder 12 allows the hydraulic breaker 11 to penetrate deeper into the tunnel. The crushing mechanism can easily complete deep crushing without the need for the trolley to move, which is also conducive to improving the crushing efficiency. The robotic arm assembly 1 can also move the push slide 10 in the vertical direction through the first pitch mechanism 13 and the second pitch mechanism 14, and make the breaker hammer 11 move in the horizontal direction through the first rotation mechanism 3 and the swing mechanism 5. Through the cooperation of the first rotation mechanism 3 and the swing mechanism 5, the breaker hammer 11 can also maintain its vertical setting on the working face when it moves in the horizontal direction. Thus, the crushing mechanism assembly 25 gives the breaker hammer 11 a large range for vertical crushing on the working face.

[0049] Furthermore, in this embodiment, the present invention does not impose any particular limitation on the first rotary mechanism 3. Any rotary mechanism known to those skilled in the art that can perform rotation on a horizontal plane can be used. Those skilled in the art can select and adjust according to specific application conditions and product requirements.

[0050] Furthermore, in this embodiment, the present invention does not impose any particular limitation on the rotary component 7. Any rotary mechanism known to those skilled in the art that can achieve rotation in a vertical plane can be used. Those skilled in the art can select and adjust it according to specific application conditions and product requirements.

[0051] Furthermore, in this embodiment, a spray assembly 21 is provided on the propulsion slide 10. The present invention does not impose any particular limitation on the spray assembly 21. Any assembly known to those skilled in the art can be used to achieve water spraying to soften soil clods, reduce dust, and impact rocks, so as to facilitate the crushing work of the breaker hammer 11 on the difficult soil clods / rocks on the working face. Those skilled in the art can select and adjust it according to the specific application and product requirements.

[0052] Furthermore, in this embodiment, the first slewing mechanism 3 is mounted on the vehicle body. The first slewing mechanism 3 includes a slewing seat and a slewing cylinder 40. The slewing seat is mounted on the vehicle body, allowing it to rotate on the vehicle body. The slewing cylinder 40 is symmetrically mounted on both sides of the slewing seat. One end of the slewing cylinder 40 is connected to the slewing seat, and the other end is connected to the vehicle body, allowing the slewing cylinder 40 to extend and retract, driving the slewing seat to perform a slewing motion. This is suitable for situations where the first slewing mechanism 3 does not need to perform a large slewing range.

[0053] Furthermore, in this embodiment, the rotary cylinder 40 is connected to the third cylinder 20 of the swing mechanism 5 via an oil circuit, so that when the swing cylinder drives the swing seat 19 to swing to the left, the rotary cylinder 40 drives the rotary seat to move to the right, thereby enabling the crushing mechanism assembly 25 to self-adjust, so that the breaker hammer 11 is always perpendicular to the face to be crushed. Example

[0054] This application discloses a trolley with a crushing mechanism assembly 25.

[0055] refer to Figures 4-8 The trolley includes a chassis assembly 22, a cab 23, a protective cover 24, and a crushing mechanism assembly 25. The cab 23, the protective cover 24, and the crushing mechanism assembly 25 are all located on the chassis assembly 22. The cab 23 is located on the upper left side of the chassis assembly 22. A groove 26 is provided on the lower right wall of the cab 23. The crushing mechanism assembly 25 is located at the right front of the cab 23, and part of the crushing mechanism assembly 25 is located in the groove 26 of the cab 23. The protective cover 24 covers the chassis assembly 22 on the right side of the cab 23. The protective cover 24 also covers the chassis assembly 22 behind the cab 23. The protective cover 24 contains a radiator, an electrical control box, etc. By placing the crushing mechanism assembly 25 and the protective cover 24 on the right, the overall length of the trolley with the crushing mechanism assembly 25 is effectively shortened.

[0056] The chassis assembly 22 includes track wheels and a frame. The frame is connected to the track wheels, which are located on the lower front of the frame. This allows the track wheels to effectively support the weight of the crushing mechanism assembly 25 located at the front of the frame. The track wheels also have strong obstacle-crossing ability, strong climbing ability, and strong load-bearing capacity, making them highly adaptable to various road conditions at construction sites. Because the overall length of the trolley is relatively short, the required length of the track wheels is also shorter, effectively reducing the overall cost of the vehicle.

[0057] The cab 23 includes a cab shell 27, a seat 28, a first operating component 29, and a second operating component 32. The first operating component 29 is located at the front inside the cab shell 27, and the seat 28 is located at the rear inside the cab shell 27. There is a gap between the first operating component 29 and the seat 28 to allow the user to have legroom. The lower part of the right wall of the cab shell 27 is bent to form a structure with a groove 26 on the outer wall and a protrusion 31 on the inner wall. The second operating component 32 is located on the protrusion 31 inside the cab shell 27 and is located to the right of the seat 28, which facilitates the driver's operation in the cab 23. A hydraulic valve block 30 is provided under the seat 28 to effectively compress the overall space required for the cab 23 and further reduce the overall length of the trolley.

[0058] The specific structure of the crushing mechanism assembly 25 is described in Example 1 and will not be repeated here.

[0059] Furthermore, in this embodiment, a support leg mechanism 33 is inclinedly arranged inside the rear part of the protective cover 24. The support leg mechanism 33 includes a support leg assembly 34 and a support 35. The support leg assembly 34 includes an outer support leg cylinder 41, an inner support leg 42, and a support leg cylinder. A protrusion is provided on the front side of the lower part of the outer support leg cylinder 41. The upper end of the outer support leg cylinder 41 is connected to the protective cover 24. The protrusion on the front side of the outer support leg cylinder 41 is connected to the rear end of the chassis assembly 22, so that the outer support leg cylinder 41 is stably restricted within the rear end of the chassis assembly 22 and the rear part of the protective cover 24. Moreover, the lower part of the outer support leg cylinder 41 is inclined away from the chassis assembly 22, effectively... The location of the outrigger structure is hidden, reducing the space occupied by the outrigger structure and optimizing the torque of the outrigger mechanism 33 supporting the whole vehicle. The outrigger cylinder is located inside the outer cylinder 41 of the outrigger. One end of the outrigger cylinder is hinged to the inner end of the outer cylinder 41 of the outrigger, and the other end is connected to the inner outrigger 42. The lower end of the inner outrigger 42 is hinged to the support 35. The support 35 includes a base plate, which includes two rocker sections and a flat section. The two rocker sections are located on the front and rear sides of the flat section, respectively. The rocker sections and the flat section are integrally formed and the connection is smooth. Compared with traditional vertical telescopic outriggers, this outrigger can better limit the backward horizontal displacement of the equipment during operation.

[0060] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
