Description

Technical Field

[0001] This invention relates to the field of construction machinery technology, specifically to a balanced lifting bucket structure and loader. Background Technology

[0002] Loaders are a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. They are mainly used for loading bulk materials, and can also perform light digging operations on ores and hard soil. They can also push and transport soil, level the ground, and tow other machinery. Because loaders have advantages such as fast operating speed, high efficiency, good maneuverability, and easy operation, they have become one of the main types of machinery used in earthmoving construction projects.

[0003] Traditional loaders use a boom to drive the bucket to lift and lower, and a cylinder to control the bucket's tilting, thus achieving the lifting and tilting of the bucket for loading operations. However, traditional loaders cannot guarantee the bucket's lifting balance and stability, which can easily lead to increased wear between parts and affect service life. Furthermore, if the cylinder suddenly fails during operation, the bucket will not be able to tilt, making it impossible to work and resulting in low work efficiency. Summary of the Invention

[0004] One objective of this invention is to provide a balanced lifting bucket structure to solve the technical problems of unbalanced lifting and poor stability of the bucket in the prior art, which affects the service life of the equipment, and the bucket cannot be turned over when it malfunctions, resulting in low work efficiency; the second objective is to provide a loader.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A balanced lifting bucket structure includes a bucket and a mounting bracket, wherein the bucket is mounted on the mounting bracket; and further includes:

[0007] A lifting structure is mounted on a mounting bracket. The lifting structure includes a first tilting component and a second tilting component. The first tilting component is connected to one end of the bucket, and the second tilting component is connected to the other end of the bucket. The first tilting component is used to drive one end of the bucket to lift and lower, and the second tilting component is used to drive the other end of the bucket to lift and lower.

[0008] The driving device includes a first driving device and a second driving device, both of which are mounted on a mounting bracket; the first driving device is connected to a first tilting assembly and is used to drive the first tilting assembly to raise and lower one end of the bucket; the second driving device is connected to a second tilting assembly and is used to drive the second tilting assembly to raise and lower the other end of the bucket.

[0009] According to the above technical means, by driving the first tilting component with the first drive device and the second tilting component with the second drive device, both ends of the bucket can be raised and lowered synchronously to ensure the lifting and lowering balance and stability of the bucket. It can also raise and lower one end of the bucket to achieve tilting and tilting, facilitating bucket operation and ensuring work efficiency. During operation, the first tilting component is raised and lowered by the first drive device or the second tilting component is raised and lowered by the second drive device, causing the bucket to tilt for loading or unloading operations. Even if the first or second drive device malfunctions, the bucket can still tilt and operate, ensuring work efficiency and practicality. When the bucket is full, the first and second drive devices simultaneously drive the first and second tilting components to raise and lower, allowing both ends of the bucket to rise and lower synchronously. This ensures the lifting and lowering balance and stability of the bucket, avoids shaking or tilting during lifting and lowering, reduces wear between parts, extends equipment lifespan, and improves work efficiency.

[0010] Furthermore, one end of the second driving device is connected to the first flipping component, and the other end of the second driving device is connected to the second flipping component.

[0011] According to the above technical means, when the second drive device is not working, the first drive device can drive the first tilting component to drive the second drive device to drive the second tilting component, so that the bucket can quickly tilt and tilt to the required angle. When the first drive device is not working, the second drive device can drive the second tilting component and simultaneously drive the first tilting component, so that the bucket can quickly tilt and tilt to the required angle, thereby improving work efficiency and saving costs.

[0012] Furthermore, the first tilting assembly includes two first transmission rods, a first connecting rod, and a first sleeve. The two first transmission rods are hinged to the mounting bracket and arranged parallel to each other. The two ends of the first connecting rod are respectively connected to one end of the two first transmission rods, and the other ends of the two first transmission rods are respectively hinged to a first support rod. The ends of the two first support rods away from the first transmission rods are connected to one end of the bucket. The first sleeve is rotatably sleeved on the first connecting rod. The first driving device is hinged to the mounting bracket, and the output end of the first driving device is connected to the first sleeve.

[0013] According to the above-mentioned technical means, the output end of the first drive device drives the first support rod through two first transmission rods, a first connecting rod and a first sleeve to drive one end of the bucket to rise and fall. It has good transmission performance. When working, the first drive device drives the first sleeve to drive the first connecting rod to rise and fall, thereby driving one end of the two first transmission rods to rise and fall, so that the two first transmission rods rotate along the hinge point to drive the other end of the two first transmission rods to rise and fall, thereby driving one end of the bucket to rise and fall through the two first support rods. It has a compact structure and strong practicality.

[0014] Furthermore, the second tilting assembly includes two second transmission rods, a second connecting rod, and a second sleeve. The two second transmission rods are hinged to the mounting bracket and arranged parallel to each other. The two ends of the second connecting rod are respectively connected to one end of the two second transmission rods, and the other ends of the two second transmission rods are respectively hinged to a second support rod. The ends of the two second support rods away from the second transmission rods are connected to the other end of the bucket. The second sleeve is rotatably sleeved on the second connecting rod. The other end of the second driving device is connected to the second sleeve.

[0015] According to the above-mentioned technical means, the output end of the second drive device drives the second support rod through two second transmission rods, a second connecting rod, and a second sleeve to drive the other end of the bucket to rise and fall. It has good transmission performance. When working, the second drive device drives the second sleeve to drive the second connecting rod to rise and fall, thereby driving one end of the two second transmission rods to rise and fall, so that the two second transmission rods rotate along the hinge point to drive the other end of the two second transmission rods to rise and fall, thereby driving the other end of the bucket to rise and fall through the two second support rods. It has a compact structure and strong practicality.

[0016] Furthermore, the first flipping assembly also includes two third transmission rods, a third connecting rod, and a third sleeve. The two third transmission rods are arranged parallel to each other, and one end of each of the two third transmission rods is vertically fixed to one of the first transmission rods, while the other end is connected to both ends of the third connecting rod. The third sleeve is rotatably mounted on the third connecting rod. One end of the second driving device is connected to the third sleeve.

[0017] According to the above technical means, when the second drive device is not working, the first drive device drives the first sleeve to raise and lower the first connecting rod, thereby raising and lowering one end of the two first transmission rods. Simultaneously, the other ends of the two first transmission rods drive the other end of the bucket to raise and lower via the two first support rods. At the same time, the other ends of the two first transmission rods also respectively drive the two third transmission rods to raise and lower the third connecting rod, thereby raising and lowering one end of the second drive device via the third sleeve. This causes the other end of the second drive device to raise and lower the second connecting rod via the second sleeve, thereby raising and lowering one end of the two second transmission rods. The other ends of the two second transmission rods then drive the bucket to raise and lower via the two second support rods. The other end of the bucket is raised and lowered to achieve rapid tilting and tipping of the bucket. When the first drive device is not working, the other end of the second drive device drives the second sleeve to raise and lower the second connecting rod, thereby raising and lowering one end of the two second transmission rods. The other end of the two second transmission rods drives the other end of the bucket to raise and lower through the two second support rods. At the same time, under the interaction of forces, one end of the second drive device drives the third connecting rod through the third sleeve to drive the two third transmission rods, thereby causing the two first transmission rods to rotate along their hinge points, thereby raising and lowering one end of the bucket through the two first support rods, thus achieving rapid tilting and tipping of the bucket. It has good linkage, compact structure, and strong practicality.

[0018] Furthermore, both of the second transmission rods are L-shaped.

[0019] Based on the above technical means, both second transmission rods are L-shaped, resulting in better transmission performance, a compact structure, and strong practicality.

[0020] A loader includes a vehicle body and the aforementioned balanced lifting bucket structure, the bucket structure being mounted on the vehicle body.

[0021] Furthermore, it also includes an escalator structure, which is installed on the vehicle body. The escalator structure includes steps, and support columns are installed on both sides of the steps, with handrails installed on the support columns.

[0022] Based on the aforementioned technical means, steps can be set up to facilitate staff getting on and off, while also providing support for the vehicle body to ensure its stability.

[0023] Furthermore, the escalator structure also includes an inclined plate, a sleeve, a rotating shaft, and a fastening ring; the fastening ring is sleeved on the support column, the sleeve is fixed on the fastening ring, and the rotating shaft is rotatably inserted inside the sleeve; the inclined plate is located on the step, and the inclined plate is connected to the rotating shaft; the fastening ring is provided with an adjustment knob, which is used to adjust the tightness of the fastening ring on the support column.

[0024] According to the above technical means, when it is necessary to transport goods onto the vehicle body, the inclined plate is placed on the step by fastening ring, sleeve and rotating shaft. When the inclined plate is not needed, it can be folded up to be parallel to the support column by sleeve and rotating shaft, so that the staff can get on and off.

[0025] Furthermore, it also includes a control device, which is mounted on the vehicle body and is connected to the first drive device and the second drive device.

[0026] Based on the above-mentioned technical means, the control device is connected to the first drive device and the second drive device, resulting in a high degree of automation and convenient operation.

[0027] The beneficial effects of this invention are:

[0028] This invention uses a first driving device to drive a first tilting component and a second driving device to drive a second tilting component, enabling the two ends of the bucket to rise and fall synchronously. This ensures good lifting balance and stability of the bucket, and also allows one end of the bucket to rise and fall, achieving bucket tilting and tilting for easier operation and improved work efficiency. During operation, the first driving device drives the first tilting component to rise and fall, or the second driving device drives the second tilting component to rise and fall, tilting the bucket to facilitate loading or unloading. Even if the first or second driving device malfunctions, the bucket can still tilt and operate, ensuring high work efficiency and practicality. When the bucket is full, the first and second driving devices simultaneously drive the first and second tilting components to rise and fall, respectively, allowing the two ends of the bucket to rise and fall synchronously. This ensures good lifting balance and stability, prevents shaking or tilting of the bucket during lifting and falling, reduces wear between parts, extends equipment life, and improves work efficiency.

Detailed Implementation

[0035] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] In this embodiment, a bucket structure with balanced lifting and lowering is described, such as... Figure 1 As shown, the device includes: a bucket 1 and a mounting bracket 2, with the bucket 1 mounted on the mounting bracket 2; it also includes a lifting structure 3, which is mounted on the mounting bracket 2 and includes a first tilting component 31 and a second tilting component 32; the first tilting component 31 is connected to one end of the bucket 1, and the second tilting component 32 is connected to the other end of the bucket 1; the first tilting component 31 is used to drive one end of the bucket 1 to lift, and the second tilting component 32 is used to drive the other end of the bucket 1 to lift; and a driving device, including a first driving device 4 and a second driving device 5, both mounted on the mounting bracket 2; the first driving device 4 is connected to the first tilting component 31 and is used to drive the first tilting component 31 to drive one end of the bucket 1 to lift; the second driving device 5 is connected to the second tilting component 32 and is used to drive the second tilting component 32 to drive the other end of the bucket 1 to lift.

[0038] In this embodiment, the first driving device 4 drives the first tilting assembly 31, and the second driving device 5 drives the second tilting assembly 32. This allows both ends of the bucket 1 to rise or fall synchronously, ensuring good lifting balance and stability of the bucket 1. It also allows only one end of the bucket 1 to rise or fall, achieving tilting and tilting of the bucket 1 to facilitate bucket operation and ensure work efficiency. Figure 1 As shown, specifically, during operation, the first drive device 4 drives the first tilting assembly 31 to raise one end of the bucket 1, or the second drive device 5 drives the second tilting assembly 32 to lower the other end of the bucket 1. This allows the bucket 1 to tilt and tilt for loading or unloading. Even if the first drive device 4 or the second drive device 5 malfunctions, the bucket 1 can still tilt, ensuring high work efficiency and practicality. When the first drive device 4 and the second drive device 5 simultaneously drive the first tilting assembly 31 and the second tilting assembly 32 to rise or fall, both ends of the bucket 1 can rise or fall synchronously, ensuring the lifting and lowering balance of the bucket 1, good stability, avoiding shaking, swaying, and tilting of the bucket 1 during lifting and lowering, reducing wear between parts, extending equipment life, and improving work efficiency. Both the first drive device 4 and the second drive device 5 can be cylinders.

[0039] In this embodiment, one end of the second driving device 5 is connected to the first flipping component 31, and the other end of the second driving device 5 is connected to the second flipping component 32; as shown Figure 1 As shown, specifically, when the second drive device 5 is not working, it can serve as an intermediate connecting rod between the first tilting assembly 31 and the second tilting assembly 32. When the first drive device 4 drives the first tilting assembly 31 to raise one end of the bucket 1, the first tilting assembly 31 can also drive the second tilting assembly 32 through the second drive device 5 to lower the other end of the bucket 1, so that the bucket 1 can quickly tilt and tilt to the required angle. When the first drive device 4 is not working, when the second drive device 5 drives the second tilting assembly 32 to lower the other end of the bucket 1, through the interaction of forces, one end of the second drive device 5 drives the first tilting assembly 31, thereby raising one end of the bucket 1, so that the bucket 1 can quickly tilt and tilt to the required angle, improving work efficiency and saving costs.

[0040] In this embodiment, the first tilting assembly 31 includes two first transmission rods 311, a first connecting rod 312, and a first sleeve 313. The two first transmission rods 311 are hinged to the mounting bracket 2 and are arranged parallel to each other. The two ends of the first connecting rod 312 are respectively connected to one end of the two first transmission rods 311. The other ends of the two first transmission rods 311 are respectively hinged to a first support rod 314. The ends of the two first support rods 314 away from the first transmission rods 311 are connected to one end of the bucket 1. The first sleeve 313 is rotatably sleeved on the first connecting rod 312. The first driving device 4 is hinged to the mounting bracket 2, and the output end of the first driving device 4 is connected to the first sleeve 313.

[0041] In this embodiment, the output end of the first drive device 4 drives the first support rod 314 through two first transmission rods 311, a first connecting rod 312, and a first sleeve 313 to raise and lower one end of the bucket 1. This results in good transmission performance. Specifically, as shown... Figure 2 As shown, during operation, the first drive device 4 drives the first sleeve 313 to raise or lower the first connecting rod 312, thereby raising or lowering one end of the two first transmission rods 311. This causes the two first transmission rods 311 to rotate along their hinge points, so that the other ends of the two first transmission rods 311 lower or rise, thereby driving the two first support rods 314 to raise or lower one end of the bucket 1. The structure is compact and highly practical.

[0042] In this embodiment, the second tilting assembly 32 includes two second transmission rods 321, a second connecting rod 322, and a second sleeve 323. The two second transmission rods 321 are hinged to the mounting bracket 2 and are arranged parallel to each other. The two ends of the second connecting rod 322 are respectively connected to one end of the two second transmission rods 321. The other ends of the two second transmission rods 321 are respectively hinged to a second support rod 324. The ends of the two second support rods 324 away from the second transmission rods 321 are respectively connected to the other end of the bucket 1. The second sleeve 323 is rotatably sleeved on the second connecting rod 322. The other end of the second driving device 5 is connected to the second sleeve 323.

[0043] In this embodiment, the output end of the second drive device 5 drives the second support rod 324 through two second transmission rods 321, a second connecting rod 322, and a second sleeve 323 to lift and lower the other end of the bucket 1. This results in good transmission performance. Specifically, as shown... Figure 3 As shown, during operation, the other end of the second drive device 5 drives the second sleeve 323 to raise or lower the second connecting rod 322, thereby raising or lowering one end of the two second transmission rods 321. This causes the two second connecting rods 322 to rotate along their hinge points, so that the other ends of the two second transmission rods 321 lower or rise, thereby driving the two second support rods 324 to raise or lower the other end of the bucket 1. The structure is compact and highly practical.

[0044] In this embodiment, the first flipping assembly 31 further includes two third transmission rods 315, a third connecting rod 316, and a third sleeve 317. The two third transmission rods 315 are arranged parallel to each other, and one end of each of the two third transmission rods 315 is vertically fixed to one of the first transmission rods 311, and the other end is connected to both ends of the third connecting rod 316. The third sleeve 317 is rotatably mounted on the third connecting rod 316. One end of the second driving device 5 is connected to the third sleeve 317.

[0045] This implementation example Figures 1-3 As shown, specifically, when the second drive device 5 is not working, it can act as an intermediate connecting rod between the third sleeve 317 and the second sleeve 323. When the first drive device 4 drives the first sleeve 313 to lower the first connecting rod 312, thereby driving the two first transmission rods 311 to drive the two first support rods 314 to raise one end of the bucket 1, the two first transmission rods 311 also drive the two third transmission rods 315 to raise the third connecting rod 316. This, in turn, drives the second drive device 5 through the third sleeve 317 to raise the second sleeve 323. The second sleeve 323 then drives the second connecting rod 322 to drive the two second transmission rods 321 to drive the two second support rods 324 to raise the other end of the bucket 1. The bucket 1 descends, allowing it to quickly tilt and flip to the required angle. When the first drive device 4 is not working, the second sleeve 323 at the other end of the second drive device 5 drives the second connecting rod 322 to descend, thereby driving the two second transmission rods 321 to drive the two second support rods 324 to lift the other end of the bucket 1. Through the interaction of forces, one end of the second drive device 5 drives the third connecting rod 316 through the third sleeve 317 to drive the two third transmission rods 315 to drive the two first transmission rods 311 to rotate along their hinge points, thereby driving the one end of the bucket 1 to rise through the two first support rods 314, allowing the bucket 1 to quickly tilt and flip to the required angle. It has good linkage, compact structure, and strong practicality.

[0046] In this embodiment, both second transmission rods 321 are L-shaped; specifically, as shown in the figure... Figure 3 As shown, both second transmission rods 321 are L-shaped. The horizontal bar of the L-shape is parallel to the first transmission rod 311, and the vertical bar of the L-shape is parallel to the third transmission rod 315. This results in better transmission performance, a compact structure, and strong practicality.

[0047] A loader includes a vehicle body 6 and the aforementioned balanced lifting bucket structure, the bucket structure being mounted on the vehicle body 6.

[0048] The bucket structure is installed at the rear of the vehicle body 6. During operation, the first drive device 4 drives the first tilting component 31 to raise one end of the bucket 1, or the second drive device 5 drives the second tilting component 32 to lower the other end of the bucket 1, so that the bucket 1 tilts and tilts to facilitate loading or unloading. The first drive device 4 and the second drive device 5 drive the first tilting component 31 and the second tilting component 32 to rise or fall simultaneously, so that both ends of the bucket 1 rise or fall synchronously, to ensure the lifting and lowering balance performance and stability of the bucket 1, to avoid shaking, swaying and tilting of the bucket 1 during the lifting and lowering process, to reduce wear between parts, extend the service life of the equipment and improve work efficiency.

[0049] In this embodiment, an escalator structure 7 is also included. The escalator structure 7 is installed on the vehicle body 6. The escalator structure 7 includes steps 71, and support columns 72 are installed on both sides of the steps 71. Handrails 73 are installed on the support columns 72. The vehicle body 6 is provided with a driver's cab. When not in use, the escalator structure 7 can be stored in the driver's cab of the vehicle body 6. When in use, the escalator structure 7 can be installed at the door of the driver's cab of the vehicle body 6 and supported on the ground. Specifically, as shown above... Figure 4 As shown, steps 71 are set between the vehicle body 6 and the ground to facilitate the movement of staff up and down, while also providing support for the vehicle body 6 to ensure its stability.

[0050] In this embodiment, the escalator structure 7 further includes an inclined plate 74, a sleeve 75, a rotating shaft 76, and a fastening ring 77; the fastening ring 77 is sleeved on the support column 72, the sleeve 75 is fixed on the fastening ring 77, and the rotating shaft 76 is rotatably inserted inside the sleeve 75; the inclined plate 74 is located on the step 71, and the inclined plate 74 is connected to the rotating shaft 76; an adjusting knob 78 is provided on the fastening ring 77, and the adjusting knob 78 is used to adjust the tightness of the fastening ring 77 on the support column 72; specifically, as shown... Figure 5 As shown, when goods need to be transported into the cab, the inclined plate 74 is placed on the step 71 by means of the fastening ring 77, the sleeve 75 and the pivot 76. When the inclined plate 71 is not needed, the inclined plate 74 can be folded parallel to the support column 72 by means of the sleeve 75 and the pivot 76, which makes it convenient for workers to go up and down. At the same time, the tightness of the fastening ring 77 on the support column 72 can be adjusted by means of the adjusting knob 78, which makes it easy to store the ladder structure 7.

[0051] In this embodiment, a control device 8 is also included. The control device 8 is mounted on the vehicle body 6 and is controllably connected to the first drive device 4 and the second drive device 5; for example... Figure 1 As shown, the control device 8 is connected to the first drive device 4 and the second drive device 5, resulting in a high degree of automation and convenient operation.
