[0037] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.
[0038] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0039] This application provides a work machinery 100, please refer to... Figures 1 to 7 The working machinery 100 includes a base frame 1, a turntable 2, a telescopic boom 3, outriggers 4, a hydraulic oil tank 5, and a power unit 6. The turntable 2 is mounted on the base frame 1 and can rotate around its rotation center D. The telescopic boom 3 is mounted on the turntable 2. Multiple outriggers 4 are spaced circumferentially around the rotation center D on the base frame 1. The hydraulic oil tank 5 supplies hydraulic oil, and the power unit 6 provides power. The hydraulic oil tank 5 and the power unit 6 are respectively mounted on both sides of the turntable 2 along a first direction, which is perpendicular to the vertical direction.
[0040] For example, the hydraulic tank 5 can supply oil to the telescopic boom 3, and the power unit 6 can provide power to the turntable 2, the telescopic boom 3 and the outriggers 4.
[0041] For example, the working machinery 100 may be a crane or a hoist.
[0042] The work machinery 100 provided in this application, by mounting the turntable 2 on the base frame 1 and the telescopic boom 3 on the turntable 2, allows the telescopic boom 3 to rotate around the rotation center D to adapt to different working angles, thus exhibiting strong adaptability. By mounting the outriggers 4 on the base frame 1 to support the ground, the size difference between the work machinery 100 and the ground can be compensated, improving the stability of the work machinery 100. By mounting the hydraulic cylinders and power unit 6 on both sides of the turntable 2 along the first direction to act as counterweights, on the one hand, the overall stability of the work machinery 100 can be further improved; on the other hand, by using the hydraulic tank 5 and power unit 6 as counterweights, the use of counterweight blocks can be reduced, thereby reducing the overall weight of the work machinery 100, achieving lightweighting. This not only reduces the damage to the ground caused by the work machinery 100 but also increases its working height and facilitates relocation and transportation.
[0043] For example, in one embodiment, the first direction can be the left-right direction, and the second direction can be the front-back direction.
[0044] It should be noted that "up" refers to the direction towards the ceiling, and "down" is the opposite of "up." The up-down, front-back, and left-right directions are perpendicular to each other, forming a three-dimensional vertical coordinate system.
[0045] In one exemplary embodiment, Figure 1 In this context, R1 can be the first direction, R2 can be the second direction, and R3 can be the up or down direction.
[0046] In one embodiment, for example, the rotation center D may extend in the vertical direction.
[0047] As an example, in one embodiment, please refer to Figure 6 The slewing center D passes through the center of gravity G5 of the underframe.
[0048] It is understandable that when the telescopic boom 3 is in the lifting working state, the center of gravity of the telescopic boom 3 is located behind the rotation center D of the turntable 2. By setting the hydraulic oil tank 5 and the power unit 6 on both sides of the turntable 2 along the first direction to act as counterweights, the use of counterweight blocks can be reduced to reduce the weight of the working machinery 100, while still meeting the requirements for lifting weight and lifting height.
[0049] In one embodiment, please refer to Figure 4 The number of support legs 4 is multiple, and the multiple support legs 4 are arranged at intervals along the circumference of the rotation center D on the base frame 1.
[0050] For example, the number of outriggers 4 can be four, and the four outriggers 4 are spaced apart on the base frame 1 along the circumferential direction of the rotation center D. In this way, multiple outriggers 4 can be supported on the ground along the circumferential direction of the rotation center D, so as to facilitate the lifting of the working machinery 100 and further improve the working stability of the working machinery 100.
[0051] In one embodiment, please refer to Figure 4 and Figure 5 The outrigger 4 is rotatably connected to the base frame 1. The working machine 100 includes a swing cylinder 7, which is mounted on the base frame 1 and is used to drive the outrigger 4 to rotate circumferentially.
[0052] For example, a mounting plate 11 is provided on the top of the base frame 1. The mounting plate 11 has an outwardly protruding connecting part 111. One end of the support leg 4 is rotatably connected to the connecting part 111. The cylinder 71 of the swing cylinder is rotatably hinged to the mounting plate 11, and the telescopic rod 72 of the swing cylinder is rotatably hinged to the support leg 4. The rotation axis of the cylinder 71 of the swing cylinder and the mounting plate 11, as well as the rotation axis of the telescopic rod 72 of the swing cylinder and the support leg 4, are all parallel to the rotation center D, that is, in the vertical direction. In this way, the telescopic rod 72 of the swing cylinder can drive the support leg 4 to rotate around the rotation center D by extending and retracting, so as to better adapt to the needs of mountain operations.
[0053] In one embodiment, please refer to Figure 4 and Figure 5 There are multiple swing cylinders 7, and each swing cylinder 7 is driven by a corresponding support leg 4.
[0054] For example, there can be four swing cylinders 7, each swing cylinder 7 being driven and connected to a corresponding outrigger 4. Thus, when the working machinery 100 is not lifting, two outriggers 4 form a group, with the two groups spaced apart along a second direction, and two outriggers 4 in each group spaced apart along a first direction. When the working machinery 100 is lifting, each swing cylinder 7 drives its corresponding outrigger 4 to rotate around the rotation center D, opening the angle between the two outriggers 4 in each group, so that the four outriggers 4 extend radially around the rotation center D. This allows for a large span, enabling the outriggers 4 to rotate according to the actual needs of the construction site during the movement of the working machinery 100, avoiding obstacles, better adapting to operational needs, and exhibiting good working stability and strong adaptability.
[0055] In one embodiment, please refer to Figure 4 and Figure 5 The outrigger 4 includes a rotating arm 41 and a lifting cylinder 42. The rotating arm 41 is rotatably connected to the base frame 1. The rotating arm 41 includes multiple rotating sections 411, which can extend and retract along a direction perpendicular to their rotation axis. The swing cylinder 7 is drivenly connected to the rotating arm 41. The lifting cylinder 42 is mounted on the rotating arm 41 and extends and retracts in the vertical direction.
[0056] For example, the rotating arm 41 may include two rotating arm sections 411, namely a first rotating arm 4111 and a second rotating arm 4112. The second rotating arm 4112 is telescopically located within the first rotating arm 4111. The first rotating arm 4111 is rotatably connected to the connecting part 111. The telescopic rod 72 of the swing cylinder can be rotatably connected to the first rotating arm 4111. The cylinder of the lifting cylinder 42 can be mounted on the second rotating arm 4112. The telescopic rod of the lifting cylinder 42 extends and retracts in the vertical direction. In this way, by setting the lifting cylinder 42 on the rotating arm 41 to extend and retract in the vertical direction, the size difference between the outrigger 4 and the ground can be compensated, the support of the outrigger 4 to the ground can be enhanced, and the support stability of the working outrigger 4 can be improved.
[0057] In related technologies, the jib of working machinery such as cranes often adopts a truss structure, and the jib is only used to assist in lifting.
[0058] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The telescopic boom 3 includes a main boom 31, a main telescopic cylinder 32, a jib 33, and a jib 34. The main boom 31 is rotatably mounted on the turntable 2. The main telescopic cylinder 32 is telescopically supported between the turntable 2 and the main boom 31. The jib 33 is rotatably mounted at the end of the main boom 31 away from the turntable 2, and is used to lift heavy objects E. The jib 34 is telescopically supported between the main boom 31 and the jib 33.
[0059] For example, the main boom 31 may include six main boom sections 311. The main boom sections 311 closest to the turntable 2 are rotatably connected to the turntable 2. The main boom section 311 furthest from the turntable 2 among two adjacent main boom sections 311 can be telescopically positioned within the main boom section 311 closest to the turntable 2. The cylinder 321 of the main telescopic cylinder can be mounted on the turntable 2. The telescopic rod 322 of the main telescopic cylinder is drivenly connected to the main boom section 311 closest to the turntable 2. Thus, when the main telescopic cylinder 32 operates, it can adjust the angle between the main boom 31 and the turntable 2 to lift the main boom 31. This allows for adjustment of the working range of the telescopic boom 3, providing strong adaptability. The auxiliary boom 33 may include two auxiliary boom sections 331. The auxiliary boom section 331 closest to the turntable 2 can be rotatably connected to the main boom section 311 furthest from the turntable 2 among the six main boom sections 311. The auxiliary boom section 331 furthest from the turntable 2 among the two auxiliary boom sections 331 is equipped with a hook for lifting heavy objects E. The auxiliary telescopic cylinder 34 is telescopically supported between the auxiliary boom section 331 closest to the turntable 2 and the main boom section 311 furthest from the turntable 2 to adjust the angle between the main boom 31 and the auxiliary boom 33, thereby raising the auxiliary boom 33 and further increasing the working range.
[0060] In one embodiment, please refer to Figure 6 When the auxiliary boom 33 is hoisting the heavy object E, the center of gravity G1 of the main boom 31 is located on the side away from the auxiliary boom 33 along the second direction from the rotation center D.
[0061] In other words, when the auxiliary boom 33 is lifting the heavy object E, the center of gravity G1 of the main boom 31 is located behind the rotation center D, so that the main boom 31 can not only provide support but also act as a counterweight. This can further improve the working stability of the operating machinery 100. Compared with operating machinery with the same lifting capacity in the prior art, the operating machinery 100 provided in this application has a high lifting height and is lightweight.
[0062] As an example, in one embodiment, please refer to Figure 6 The center of gravity G2 of the hydraulic oil tank, the center of gravity G3 of the power unit, and the center of gravity G4 of the turntable are all located on the side of the rotation center D away from the auxiliary telescopic cylinder 34 along the second direction. This allows the hydraulic oil tank 5, the power unit 6, and the turntable 2 to better play their role in counterweighting, and further improves the working stability of the machine.
[0063] In one embodiment, please refer to Figures 1 to 7 The working machine 100 includes two track frames 8, which are respectively arranged on both sides of the base frame 1 along a first direction. Here, by setting the track frames 8, movement can be achieved by using tracks 81. In this way, the weight of the working machine 100 can be distributed through the wide tracks 81. On the one hand, it can be used on uneven ground, with strong adaptability and good stability; on the other hand, it can reduce the pressure on the ground, thereby reducing damage to the ground.
[0064] In one embodiment, please refer to Figure 7 The maximum lifting height A of the working machine 100 is 65m. For example, when the telescopic rod of the lifting cylinder 42 is extended, each main boom 311 is extended, the telescopic rod 322 of the main telescopic cylinder is extended, each auxiliary boom 331 is extended, and the telescopic rod of the auxiliary telescopic cylinder 34 is extended, the maximum lifting height A of the working machine 100 can be 65m. In this way, the heavy object E can be lifted to a height of 65m, further increasing the working range of the working machine 100 and making it highly adaptable.
[0065] In one embodiment, please refer to Figure 3The maximum gradeability B of the working machinery 100 is 30°. It can be understood that gradeability B here refers to the angle between the distance between the start and end points of the ramp and its horizontal distance. The working machinery 100 provided in this application, when the main boom 31, auxiliary boom 33, and lifting cylinder 42 are all in the retracted state, can traverse a 30° ramp and can also perform lifting on a 30° ramp, demonstrating strong adaptability. In some embodiments, to improve the operational stability of the working machinery 100, after the working machinery 100 stops on the ramp, the swing cylinder 7 can be used to drive the rotation of each outrigger 4, causing each outrigger 4 to extend radially. Finally, the lifting cylinder 42 is activated to compensate for the distance between the outriggers and the ground.
[0066] In one embodiment, please refer to Figure 4 The maximum lateral travel gradient C of the operating machinery 100 is 7°. It can be understood that the lateral travel gradient C here refers to the angle of the slope faced by the operating machinery 100 during travel. The operating machinery 100 provided in this application, when the main boom 31, auxiliary boom 33, and lifting cylinder 42 are all in the retracted state, can travel on slopes with a lateral travel gradient C of 7°, and can also perform lifting on slopes with a lateral travel gradient C of 7°, demonstrating strong adaptability.
[0067] For example, in one embodiment, when both the main boom 31 and the auxiliary boom 33 are retracted, the angle between the main boom 31 and the turntable 2 is not less than 85°, and the angle between the auxiliary boom 33 and the main boom 31 is not greater than 10°, the working machine 100 can travel on a slope with a gradient B of not more than 8° when carrying a load of 5.5 tons; and when the working machine 100 is carrying a load of 2.4 tons, it can travel on a slope with a gradient B of not more than 15°.
[0068] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
