Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, and in particular to a general vehicle for roadway excavation and crushing. Background Technology

[0002] In existing tunnel excavation and crushing vehicles, the robotic arm assembly with a breaker hammer is mounted at the front of the vehicle body to allow for greater rotation space. However, this method results in a longer overall length of the vehicle and a longer chassis assembly, which in turn increases the cost of the vehicle. In existing technologies, the ends or sidewalls of the crushing components are connected to the robotic arm assembly via hinges, resulting in greater shear force and stress concentration on the crushing component body. Furthermore, the vertical crushing range that existing crushing components can perform at the tunnel face is limited, thus leaving room for improvement. Summary of the Invention

[0003] In view of this, this application provides a main vehicle for roadway excavation and crushing, which has a robotic arm assembly mounted on the upper side of the vehicle body, and a cab with a narrow bottom and wide top structure to avoid the rotary cylinder connected to the robotic arm assembly. The length of the main vehicle is further shortened by connecting the crushing components to the robotic arm assembly, and the stress on the crushing components is optimized, making the main vehicle compact, stable in performance, and low in cost. At the same time, through the functional design of the robotic arm assembly and the crushing components, the main vehicle has a large range for vertical crushing on the working face, and can also realize the rapid adjustment of the position of the crushing components, reducing equipment movement time and improving crushing efficiency and crushing force.

[0004] In summary, in order to optimize the overall layout of the roadway excavation and crushing vehicle, increase the range of vertical crushing that the roadway excavation and crushing vehicle can perform at the working face, and improve the crushing effect of the roadway excavation and crushing vehicle, this application proposes a roadway excavation and crushing vehicle.

[0005] The technical solution for a roadway excavation and crushing machine provided in this application is as follows:

[0006] A roadway excavation and crushing vehicle includes a chassis assembly, a cab, a multi-degree-of-freedom robotic arm assembly, and crushing components. The cab is connected to the chassis assembly, and the robotic arm assembly is also connected to the chassis assembly. The lower part of the cab is provided with a groove, and the robotic arm assembly is at least partially located in the groove. The crushing components are connected to the robotic arm assembly.

[0007] The robotic arm assembly includes a first rotary mechanism, a pitch mechanism, a swing mechanism, and a second rotary mechanism. The first rotary mechanism is at least partially located within the groove. 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 crushed part.

[0008] The second rotary mechanism includes a rotary assembly and a rotary table. One end of the rotary assembly is connected to the swing mechanism, and the other end is connected to the rotary table. The rotary table has a corner.

[0009] The crushing component includes a feed slide, a breaker hammer, and a feed cylinder. The feed slide is bolted to the rotary table, and the axial direction of the feed slide is consistent with the axial direction of the rotary assembly. The breaker hammer is connected to the feed slide, and one end of the feed cylinder is connected to the feed slide, while the other end is connected to the breaker hammer.

[0010] The chassis assembly is provided with a support leg mechanism at one end away from the robotic arm assembly. The distance between the upper end of the support leg mechanism and the chassis assembly is smaller than the distance between the lower end of the support leg mechanism and the chassis assembly.

[0011] By adopting the above technical solution, a groove is provided in the lower part of the cab, allowing the robotic arm assembly to be placed in the groove, thereby compressing the overall length of the cab and robotic arm assembly. Furthermore, by aligning the crushing components parallel to the rotating assembly, with some components positioned above or behind the rotating assembly, the overlap between the crushing components and the rotating assembly is maximized. This further shortens the length of the crushing components and robotic arm assembly compared to existing technologies, resulting in a significant reduction in the overall length of the roadway excavation and crushing vehicle. The compact vehicle structure further reduces the required chassis assembly, etc. It boasts relatively stable performance and low cost. The roadway excavation crushing trolley utilizes a corner-shaped rotary table to ensure the crushing components are parallel to the axial direction of the second rotary mechanism, meaning the crushing components are normally perpendicular to the working face. This allows for more convenient vertical crushing of the working face compared to conventional crushing mechanisms. The eccentrically positioned crushing components on the second rotary mechanism provide a larger range for vertical crushing of the working face, and the crushing components can be moved very easily for vertical crushing. The roadway excavation crushing trolley also utilizes a first rotary mechanism and a swing arm... The coordinated movement of the mechanism allows the crushing component to move conveniently along the horizontal axis, perpendicular to the tunnel face. It can also move conveniently along the vertical axis, perpendicular to the tunnel face, via the first and second pitching mechanisms. This gives the roadway excavation crushing trolley a large range for crushing perpendicular to the tunnel face and facilitates convenient movement of the crushing component perpendicular to the tunnel face. Simultaneously, the crushing component allows the breaker hammer to slide and extend on the feed slide. When the breaker hammer causes unevenness on the tunnel face, the extension and retraction of the feed cylinder allows the breaker hammer to... Deep crushing can be easily completed without the need for trolley movement, which helps to improve the crushing efficiency. The bolted connection between the propulsion slide and the rotary table effectively strengthens the connection between the propulsion slide and the rotary table. Moreover, the absence of a rotating connection between the propulsion slide and the rotary table reduces the damage caused by shear forces and other stresses on the propulsion slide, making the overall performance of the roadway excavation and crushing vehicle more stable. The outrigger mechanism is inclined and set at the end of the chassis assembly away from the robotic arm assembly, effectively hiding the position of the outrigger structure, reducing the space occupied by the outrigger structure, and optimizing the torque of the outrigger mechanism supporting the whole vehicle.

[0012] Preferably, the first rotary mechanism includes a rotary seat and a rotary cylinder. The rotary seat is connected to the chassis assembly, and one end of the rotary cylinder is connected to the chassis assembly and the other end is connected to the rotary seat. The swing mechanism includes a swing seat and a third cylinder. One end of the swing seat is connected to the pitch mechanism and the other end is connected to the crushing component. The third cylinder is disposed on both sides of the swing seat, with one end connected to the swing seat and the other end connected to the pitch mechanism. The rotary cylinder is connected to the third cylinder via an oil circuit.

[0013] 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.

[0014] Preferably, the propulsion slide is equipped with a spray assembly.

[0015] Preferably, the cab includes a cab shell, a seat, a first operating component, and a second operating component. The lower part of the cab shell is curved, such that the outer wall of the cab shell forms the groove, and the inner wall of the cab shell forms a protrusion. The first operating component is disposed in the cab, the seat is also located in the cab, and the second operating component is disposed on the protrusion. The cab also includes an internal hydraulic valve block located inside the seat.

[0016] 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.

[0017] Preferably, the chassis assembly includes track wheels and a frame, the frame being connected to the track wheels.

[0018] Preferably, it also includes a protective cover, which is connected to the chassis assembly, and the outrigger mechanism is located inside the protective cover; the outrigger mechanism includes an outrigger assembly, which includes an outer outrigger cylinder, an inner outrigger, and an outrigger cylinder. The lower part of the outer outrigger cylinder is provided with a protrusion plate.

The outrigger cylinder is located inside the outer outrigger cylinder, with one end connected to the outer outrigger cylinder and the other end connected to the inner outrigger.

[0019] 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.

[0020] Preferably, it also includes a protective cover, which is connected to the chassis assembly. The cab is located on one side of the chassis assembly, and the protective cover is located on the other side of the chassis assembly. The protective cover contains a radiator, an electrical control box, etc.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By providing a recess in the lower part of the cab, the robotic arm assembly is placed in the recess, thereby compressing the overall length of the cab and robotic arm assembly. Furthermore, by having the crushing components parallel to the rotating assembly, with some crushing components located above or behind the rotating assembly, the overlap range between the crushing components and the rotating assembly is large. This results in a shorter length of the crushing components and robotic arm assembly compared to existing technologies, leading to a significant reduction in the overall length of the roadway excavation and crushing vehicle. The compact structure of the vehicle results in more stable performance and lower cost for the chassis assembly and other components. The bolted connection between the propulsion slide and the rotary table effectively strengthens the connection between them. The absence of a rotating connection between the propulsion slide and the rotary table reduces the stress damage from shear forces on the propulsion slide, making the roadway excavation and crushing vehicle more stable.

[0023] 2. The roadway excavation crushing trolley uses a rotary table with corners to ensure that the crushing components are parallel to the axial direction of the second rotary mechanism, meaning the crushing components are normally perpendicular to the working face. This allows the roadway excavation crushing trolley to more conveniently crush the working face vertically compared to conventional crushing mechanisms. The eccentrically positioned crushing components on the second rotary mechanism provide a larger range for vertical crushing of the working face, and the crushing components can be moved to their vertical crushing position very easily. Furthermore, the roadway excavation crushing trolley, through the cooperation of the first rotary mechanism and the swing mechanism, allows the crushing components to move vertically along the horizontal axis. The convenient movement of the crushing machine perpendicular to the working face allows for easy movement along the vertical axis via the first and second pitching mechanisms. This gives the roadway excavation crushing machine a large range for crushing perpendicular to the working face, making it easier to move the crushing components perpendicular to the working face. Simultaneously, the crushing components allow the breaker hammer to slide and extend on the feed slide. When the breaker hammer causes unevenness in the working face, the extension and retraction of the feed cylinder allows the breaker hammer to penetrate deeper into the crushing area, achieving deep crushing conveniently without the need for the trolley to move, thus improving the crushing efficiency of the crushing operation.

[0024] 3. The outrigger mechanism is tilted and positioned at the end of the chassis assembly away from the robotic arm assembly, effectively concealing the position of the outrigger structure, reducing the space occupied by the outrigger structure, and optimizing the torque of the outrigger mechanism in supporting the entire vehicle.

[0034] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0035] This application discloses a general vehicle for roadway excavation and crushing.

[0036] Reference Figure 1 and Figure 2The system includes a chassis assembly 22, a cab 23, a protective cover 24, and a crushing mechanism assembly 25. The crushing mechanism assembly 25 includes a multi-degree-of-freedom robotic arm assembly 1 and a crushing component 2. The cab 23, the protective cover 24, and the robotic arm assembly 1 are all located on the chassis assembly 22. The crushing component 2 is located at the end of the robotic arm assembly 1 away from 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 robotic arm assembly 1 is located at the right front of the cab 23, and part of the robotic arm assembly 1 is located within the cab 23. Inside the recess 26, 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 robotic arm assembly 1 and part of the protective cover 24 on the right, the overall length of the trolley with the crushing mechanism assembly 25 is effectively shortened. Furthermore, by setting the recess 26 below the right arm of the cab 23, the operating space of the user's body inside the cab 23 is not affected, nor is the rotation space of the robotic arm assembly 1 affected, and the length of the chassis assembly 22 is also effectively reduced.

[0037] The chassis assembly 22 includes track wheels and a frame. The frame is connected to the track wheels, which are located slightly forward and below 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. Because the overall length of the trolley is relatively short, the required track wheel length is also shorter, which effectively reduces the length of the track wheels required for the roadway excavation and crushing vehicle, effectively reducing the cost of the entire vehicle and making the vehicle structure more compact. This, in turn, makes the performance of the chassis assembly 22 and other components of the vehicle more stable.

[0038] refer to Figure 3 and Figure 4 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. The remaining space in the cab 23 is effectively utilized. Through the layout of the tunnel excavation and crushing trolley, the overall space required for the tunnel excavation and crushing trolley is effectively reduced, and the overall length of the trolley is further reduced.

[0039] refer to Figure 5 , Figure 6 and Figure 7 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 77 to rotate, so that the rotating component 77 can 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.

[0044] 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.

[0045] By providing a recess 26 in the lower part of the cab 23, the robotic arm assembly 1 is partially placed in the recess 26, thereby compressing the overall length of the cab 23 and the robotic arm assembly 1. Furthermore, by aligning the crushing component 2 parallel to the rotating assembly 7, with a portion of the crushing component 2 located above or behind the rotating assembly 7, the overlap between the crushing component 2 and the rotating assembly 7 is significant. This further shortens the length of the crushing component 2 and the robotic arm assembly 1 compared to existing technologies, resulting in a substantial reduction in the overall length of the roadway excavation and crushing vehicle compared to existing technologies. The vehicle structure is compact, thus... The chassis assembly 22 required for the main crushing vehicle has relatively stable performance and low cost. The main crushing vehicle for roadway excavation uses a rotary table 8 with a corner 9 to ensure that the crushing component 2 is parallel to the axial direction of the second rotary mechanism 6, meaning the crushing component 2 is normally perpendicular to the working face. This allows the main crushing vehicle for roadway excavation to more conveniently perform vertical crushing of the working face compared to ordinary crushing mechanisms. Furthermore, the eccentric arrangement of the crushing component 2 on the second rotary mechanism 6 provides a larger range for vertical crushing of the working face, and the crushing component 2 can perform vertical crushing extremely conveniently. The tunnel excavation and crushing trolley, through the cooperation of the first rotary mechanism 3 and the swing mechanism 5, allows the crushing component 2 to move conveniently along the horizontal axis perpendicular to the tunnel face. It can also move conveniently along the vertical axis perpendicular to the tunnel face through the first pitch mechanism 13 and the second pitch mechanism 14. This gives the tunnel excavation and crushing trolley a large range for crushing perpendicular to the tunnel face and facilitates the movement of the crushing component 2 perpendicular to the tunnel face. Simultaneously, the crushing component 2 allows the breaker hammer 11 to move along the advancing slide... The sliding extension and retraction of the guide rail 10 allows the breaker 11 to penetrate deeper into the tunnel face when the face is uneven due to the unevenness caused by the breaker 11. This deep crushing can be easily completed without the need for the trolley to move, which helps to improve the crushing efficiency. The bolted connection between the guide rail 10 and the rotary table 8 effectively strengthens the connection between the guide rail 10 and the rotary table 8. Furthermore, the absence of a rotating connection between the guide rail 10 and the rotary table 8 reduces the damage caused by shear forces and other stresses on the guide rail 10, making the overall performance of the tunnel excavation and crushing vehicle more stable.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.
