[0045] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0046] See also Figure 1-5 As shown, according to an embodiment of the present application, a new mining truck steering knuckle disassembly and assembly device is provided, comprising:

[0047] A lifting bracket 1, wherein a forward moving assembly 2 is rotatably arranged between the lifting brackets 1, and the lifting bracket 1 is used to drive the forward moving assembly 2 to move along a first direction;

[0048] a clamping assembly 3, the clamping assembly 3 being connected to the forward moving assembly 2, the forward moving assembly 2 being used to drive the clamping assembly 3 to move along a second direction, the second direction being perpendicular to the first direction;

[0049] The clamping assembly 3 includes a first clamping member 31, a second clamping member 32, and a first driving member. The first driving member is disposed between the first clamping member 31 and the second clamping member 32. The first driving member is used to drive the second clamping member 32 to slide on the first clamping member 31 to clamp the steering knuckle.

[0050] The disassembly component 4 is arranged on the clamping component 3. After the clamping component 3 fixes the steering knuckle, the disassembly component 4 drives the pin to separate from the steering knuckle.

[0051] Specifically, the clamping assembly 3 includes a first clamping member 31, a second clamping member 32, and a first driver. The first driver is disposed between the first and second clamping members 31, 32. The first driver provides a stable driving force, allowing the first and second clamping members 31, 32 to fit tightly against the surface of the steering knuckle. Adaptive adjustment is performed based on the shape and size of the steering knuckle, ensuring that the knuckle will not loosen or slip during subsequent disassembly, ensuring safe and efficient disassembly.

[0052] The disassembly assembly 4 is mounted on the clamping assembly 3. After the clamping assembly 3 secures the steering knuckle, the disassembly assembly 4 can drive the pin out of the steering knuckle. Compared to the traditional manual removal of the pin, which is difficult and inefficient, the disassembly assembly 4 uses mechanical or hydraulic drive to remove the pin from the steering knuckle with a stable and powerful force. This not only greatly reduces the labor intensity of maintenance personnel but also significantly improves disassembly efficiency. It also avoids problems such as pin damage or steering knuckle deformation caused by improper manual operation, ensuring the integrity of the steering knuckle assembly and subsequent performance.

[0053] The lifting bracket 1 is designed to drive the forward assembly 2, the clamping assembly 3, and the disassembly assembly 4 in a first direction, or height. In actual operation, the lifting function of the lifting bracket 1 allows for flexible adjustment of the heights of the forward assembly 2 and the clamping assembly 3. Once the heights are adjusted, the forward assembly 2 can drive the clamping assembly 3 in a second, or horizontal, direction perpendicular to the first, facilitating accurate alignment of the clamping assembly 3 with the steering knuckle. In situations where the steering knuckle is irregularly positioned or space is limited, the horizontal movement of the clamping assembly 3 driven by the forward assembly 2 effectively overcomes the challenges of limited installation locations, enabling the clamping assembly 3 to quickly and accurately reach its target location, thereby improving the applicability and operational efficiency of the disassembly and assembly device.

[0054] Furthermore, the lifting bracket 1 can adopt a hydraulic lifting structure, using the stable driving force of the hydraulic system to achieve fast and precise height adjustment, while having good load-bearing performance to ensure stability when carrying components such as the forward moving component 2, the clamping component 3 and the steering knuckle.

[0055] Furthermore, the forward moving assembly 2 and the lifting bracket 1 are rotatably connected, and the angles of the forward moving assembly 2 and the clamping assembly 3 can be adjusted according to the real-time position of the steering knuckle, so that the clamping assembly 3 can be aligned with the steering knuckle more quickly and accurately.

[0056] Furthermore, the first driving member can be an electric push rod or a hydraulic cylinder, and the stable sliding of the second clamping member 32 can be achieved through precise control to meet the clamping force requirements of steering knuckles of different specifications and ensure the reliability and stability of clamping.

[0057] The first clamping member 31 includes:

[0058] a first connecting rod 311;

[0059] a first fixing rod 312 , which is disposed at both ends of the first connecting rod 311 , and defines a first sliding cavity in which the first driving member is disposed;

[0060] The first clamping claw 313 is symmetrically arranged on the first fixing rod 312 , and a first arc-shaped groove is defined on the first clamping claw 313 .

[0061] Specifically, the first clamping member 31 is connected to the forward moving component 2 to ensure that the first clamping member 31 can flexibly move in the second direction following the forward moving component 2. The first clamping member 31 includes a first connecting rod 311, a first fixing rod 312 and a first clamping claw 313. The first fixing rod 312 is arranged at both ends of the first connecting rod 311, and the first clamping claw 313 is symmetrically arranged on the first fixing rod 312. The shape and size of the first arc groove opened thereon are designed according to the outer contour of the steering knuckle of a common heavy-duty mining truck, which can fit closely with the surface of the steering knuckle, increase the contact area, and improve the stability and reliability of the clamping. A first sliding cavity is opened on the first fixing rod 312. The first sliding cavity not only provides a stable installation space for the first driving member, but also ensures that the first driving member can smoothly drive the second clamping member 32 to slide in the cavity.

[0062] Furthermore, the first connecting rod 311 can adopt a hollow tubular structure, which can reduce its own weight and the load of the entire clamping assembly 3 while ensuring sufficient strength. At the same time, it is convenient for internal wiring or installation of other auxiliary components, thereby improving the degree of integration of the device.

[0063] Furthermore, the surface of the first arcuate groove of the first clamping claw 313 can be provided with anti-slip grooves or an elastic buffer layer. The anti-slip grooves can increase friction with the steering knuckle surface, preventing the steering knuckle from slipping during the clamping process; the elastic buffer layer can act as a buffer during clamping, preventing damage to the steering knuckle surface and improving the stability and reliability of the clamping.

[0064] The second clamping member 32 includes:

[0065] A second connecting rod 321;

[0066] A second fixing rod 322 is provided at both ends of the second connecting rod 321. The second fixing rod 322 is slidably provided in the first sliding cavity at one end away from the second connecting rod 321 and is connected to the output end of the first driving member;

[0067] The second clamping claw 323 is symmetrically arranged on the second fixing rod 322 , and a second arc-shaped groove is formed on the second clamping claw 323 .

[0068] Specifically, the second clamping member 32 includes a second connecting rod 321, a second fixing rod 322, and a second claw 323. The second fixing rod 322 is disposed at both ends of the second connecting rod 321. The portion of the second fixing rod 322, one end away from the second connecting rod 321, slides within the first sliding cavity of the first fixing rod 312 and is connected to the output end of the first driving member. This allows the second fixing rod 322 to slide stably and linearly within the first sliding cavity under the drive of the first driving member. In actual operation, the second fixing rod 322 converts the power of the first driving member into the movement of the second claw 323. Through precise sliding control, it achieves precise coordination with the first claw 313, thereby reliably clamping the steering knuckle.

[0069] The second clamping claw 323 is symmetrically positioned on the second fixed rod 322. The second arcuate groove defined therein corresponds to the first arcuate groove of the first clamping claw 313, forming a clamping structure for the steering knuckle. The design of the second arcuate groove, similarly tailored to the shape of the heavy-duty mining truck's steering knuckle, allows for a close fit with the knuckle surface, creating multiple points of contact during clamping, effectively distributing the clamping force and preventing damage to the knuckle from excessive localized force. When the first drive member is operating, the second clamping claw 323, driven by the second fixed rod 322, moves toward the first clamping claw 313. As the second arcuate groove gradually closes with the first arcuate groove, the steering knuckle is securely clamped.

[0070] In actual operation, after the clamping assembly 3 moves to the desired position on the steering knuckle, the first driver activates, pushing the second fixing rod 322 through its output end to slide within the first sliding cavity. The second fixing rod 322 drives the second clamping claw 323 to move synchronously, and the second clamping claw 323 and the first clamping claw 313 move toward each other. The second arcuate groove gradually approaches and conforms to the first arcuate groove on the steering knuckle surface. As the first driver continues to exert force, the second clamping member 32 and the first clamping member 31 firmly clamp the steering knuckle, achieving a quick and stable fixation of the steering knuckle and creating favorable conditions for the subsequent removal of the pin by disassembling the assembly 4.

[0071] Furthermore, the second arcuate grooves of the first and second jaws 313, 323 can be designed as replaceable modular structures. When the arcuate groove surfaces become severely worn, only the corresponding module needs to be replaced, rather than the entire second jaw 323. This reduces maintenance costs and time. Furthermore, pressure sensors can be installed on the second arcuate groove modules to monitor the clamping force in real time. A feedback system can be used to adjust the output of the first drive element, ensuring that the clamping force on the steering knuckle remains within a reasonable range, preventing damage to the steering knuckle due to excessive clamping force or slipping due to insufficient clamping force.

[0072] The disassembly assembly 4 includes:

[0073] a mechanical arm 41, the mechanical arm 41 being disposed on the second fixing rod 322;

[0074] The connecting head 42 is provided on the robotic arm 41 .

[0075] Specifically, the robotic arm 41 is mounted on the second fixing rod 322. It possesses multi-degree-of-freedom motion characteristics, enabling precise angle and position adjustment within three-dimensional space. During operation, after the clamping assembly 3 securely clamps the steering knuckle, the robotic arm 41 can quickly adjust its posture based on the specific position of the pin and the required disassembly, accurately delivering the connector 42 to the target position. The connector 42 is mounted on the robotic arm 41 and has several threaded holes. During disassembly, the connector 42 can be connected to the threaded holes on the pin using bolts, achieving a tight fit. During operation, after the clamping assembly 3 secures the steering knuckle, the operator issues a disassembly command via the control system 10, which activates the robotic arm 41. Leveraging its flexible motion, the robotic arm 41 quickly moves the connector 42 to the pin position and completes the docking. The robotic arm 41 then applies the appropriate disassembly force according to a pre-set procedure, acting on the pin through the connector 42 to smoothly remove the pin from the steering knuckle. The entire disassembly process is highly automated and easy to operate, which greatly reduces manual intervention, effectively improves disassembly efficiency, and reduces safety risks and component damage risks caused by manual operation errors.

[0076] Furthermore, robotic arm 41 can be driven by either hydraulic or electric servo. Hydraulic drive offers high output force and fast response, making it suitable for disassembling larger pins with greater resistance. Electric servo drive, on the other hand, offers high precision and flexible control, enabling more precise disassembly operations. The choice can be tailored to actual needs. Furthermore, high-rigidity bearings and sealing devices can be installed at the joints of robotic arm 41 to enhance its motion stability and protective performance, reduce the impact of impurities such as dust and slag on the internal structure of robotic arm 41, and extend its service life.

[0077] The forward moving assembly 2 includes:

[0078] Move the connecting rod 21 forward;

[0079] A forward fixing rod 22 is provided at both ends of the forward connecting rod 21;

[0080] The forward support rod 23 has a first end that is slidably connected to the forward fixed rod 22 , and a second end that is connected to the first fixed rod 312 .

[0081] Specifically, the forward fixing rods 22 are mounted at both ends of the forward connecting rod 21, connecting and securing the two forward fixing rods 22. A sliding groove is provided on the forward fixing rod 22, forming a sliding connection with the first end of the forward support rod 23. This allows the forward support rod 23 to slide smoothly and precisely in a linear manner in the second direction, thereby driving the connected clamping assembly 3 to achieve position adjustment. The second end of the forward support rod 23 is connected to the first fixing rod 312 of the clamping assembly 3.

[0082] In actual operation, when the steering knuckle needs to be disassembled or assembled, the operator first adjusts the forward assembly 2 to the appropriate height using the lifting bracket 1, so that the clamping assembly 3 and the steering knuckle are at the same horizontal position. Next, the operator controls the driving mechanism of the forward assembly 2, causing the forward support rod 23 to slide within the groove of the forward fixed rod 22, driving the clamping assembly 3 to slowly move forward in the second direction until the clamping assembly 3 is accurately aligned with the steering knuckle. During this process, the forward assembly 2 can accurately drive the clamping assembly 3 to the target position, providing stable support and precise positioning for the clamping assembly 3 to clamp the steering knuckle and for the disassembly assembly 4 to remove the pin.

[0083] Furthermore, a sliding groove is provided on the forward fixed rod 22 , and a driving mechanism is installed in the sliding groove. The driving mechanism can drive the first end of the forward support rod 23 to slide in the sliding groove.

[0084] The lifting bracket 1 includes:

[0085] Bracket bottom plate 11;

[0086] A first support rod 12, wherein the first support rod 12 is symmetrically arranged on the support base plate 11;

[0087] a second support rod 13 slidably disposed on the first support rod 12 ;

[0088] The second driving member is disposed between the first support rod 12 and the second support rod 13 , and is used for driving the second support rod 13 to move on the first support rod 12 .

[0089] Specifically, the lifting bracket 1 includes a bracket base plate 11, a first bracket rod 12, a second bracket rod 13 and a second drive member. The bracket base plate 11 is a U-shaped structure that provides a stable support platform for the first bracket rod 12. The first bracket rod 12 is symmetrically arranged on the bracket base plate 11 and is fixed to the bracket base plate 11 by high-strength methods such as welding and bolting. It can withstand the weight of components such as the second bracket rod 13, the forward moving assembly 2 and the clamping assembly 3, as well as the forces generated during operation. The second bracket rod 13 is slidably arranged on the first bracket rod 12. The second drive member is arranged between the first bracket rod 12 and the second bracket rod 13 and is the core power component for realizing the lifting movement of the second bracket rod 13. The second drive member can adopt a hydraulic cylinder, an electric push rod or a screw nut transmission mechanism. The second drive member can realize the rapid lifting or fine-tuning of the second bracket rod 13 according to actual needs, ensuring that the forward moving assembly 2 and the clamping assembly 3 can accurately reach the height position adapted to the steering knuckle.

[0090] During actual operation, when different models of steering knuckles need to be disassembled or assembled, the operator activates the second drive member through the control system 10. This second drive member drives the second support rod 13 to smoothly raise and lower it on the first support rod 12. As the second support rod 13 moves, the height of the forward assembly 2 and the clamping assembly 3 connected to it also adjust synchronously until the clamping assembly 3 and the steering knuckle are in the proper working position, ready for subsequent clamping and disassembly operations.

[0091] Furthermore, a sliding groove is provided on the first support rod 12, and the second support rod 13 can slide in the sliding groove.

[0092] The third driving member 5 is further included. The third driving member 5 is disposed between the second support rod 13 and the forward fixed rod 22 . The third driving member 5 is used to drive the forward fixed rod 22 to rotate on the second support rod 13 .

[0093] Specifically, the third drive member 5 is securely connected to the second support rod 13, with its output end connected to the forward fixed rod 22. This allows the third drive member 5 to directly act on the forward assembly 2, achieving rotation of the forward fixed rod 22 without affecting the lifting function of the second support rod 13. The third drive member 5 can adopt various drive modes, such as a rotary hydraulic motor, a servo motor with a reducer, etc.

[0094] During actual operation, after the lifting bracket 1 has adjusted the forward assembly 2 and clamping assembly 3 to the desired height, if the steering knuckle requires special installation or limited space, the operator can activate the third drive member 5 through the control system 10. This third drive member 5 drives the forward fixed rod 22 to rotate on the second bracket rod 13, thereby causing the forward connecting rod 21, the forward support rod 23, and the clamping assembly 3 to undergo angular deflection. With this angular adjustment, the clamping assembly 3 can be aligned with the steering knuckle in a more optimal position, avoiding difficulties in clamping or disassembly caused by angular deviation.

[0095] It also includes a support base 6, and the bracket bottom plate 11 is slidably arranged on the support base 6.

[0096] The four corners of the support base 6 are provided with walking wheels 7 and auxiliary support legs 8.

[0097] Specifically, the support base 6 serves as the basic load-bearing platform for the entire device, providing a stable sliding track for the bracket base plate 11. Its main structure is welded from high-strength steel and has a large load-bearing capacity and deformation resistance, capable of bearing the weight of components such as the lifting bracket 1, the forward movement component 2, the clamping component 3, and the disassembly component 4. The support base 6 is provided with a slide rail or a slide groove, which forms a sliding connection with the slider or roller at the bottom of the bracket base plate 11, ensuring that the bracket base plate 11 can move horizontally smoothly on the support base 6, thereby driving the entire lifting bracket 1 and the upper components to adjust their positions, facilitating the operation of the mining truck steering knuckles in different positions.

[0098] The running wheels 7 are mounted at the four corners of the support base 6, providing convenient mobility for assembly and disassembly. Furthermore, the running wheels 7 are equipped with brakes. Once the device is moved to a desired position, the brakes lock the running wheels 7, preventing displacement during operation and ensuring safety during assembly and disassembly.

[0099] The auxiliary support legs 8 are also provided at the four corners of the support base 6, cooperating with the travel wheels 7 to enhance the stability of the device. During disassembly and assembly operations, the operator can lower the auxiliary support legs 8 through a hydraulic or mechanical drive mechanism so that their bottoms are in close contact with the ground, sharing the weight of the device and the pressure generated during operation. The auxiliary support legs 8 are usually equipped with a telescopic adjustment function, which can be adjusted in height according to the flatness of the ground to ensure that the support base 6 is in a horizontal state, thereby providing a stable support foundation for the lifting bracket 1, the forward moving assembly 2, etc. The combination of the travel wheels 7 and the auxiliary support legs 8 enables the disassembly and assembly device to maintain good stability in both the moving and operating states, effectively avoiding problems such as tilting and shaking caused by uneven ground or changes in the center of gravity of the device.

[0100] A pump station, a battery pack 9, a control system 10 and an operating room are also provided on the support base 6 and located on one side of the bracket bottom plate 11.

[0101] Specifically, the pump station, mounted on the support base 6, serves as the power source for the entire hydraulic system, connected via pipes to the first and second drive members, the drive mechanism, and other hydraulic actuators. The pump station utilizes a highly efficient and energy-efficient hydraulic pump unit that precisely adjusts the pressure and flow of hydraulic oil according to varying operational requirements, providing stable and powerful power for raising and lowering the lift bracket 1, moving the forward assembly 2, clamping the clamping assembly 3, and disassembling the assembly 4.

[0102] The battery pack 9 is mounted on the support base 6 and provides a reliable power supply for electrically powered components, such as the electrically driven third drive element 5 and the control system 10. Using high-capacity, high-energy-density lithium batteries, the battery pack 9 offers long battery life and rapid charging, meeting the power needs of the device during extended operation. Its placement on the support base 6 not only saves space within the device but also facilitates battery replacement and maintenance.

[0103] Integrated into the support base 6 and installed within the operator's cabin, control system 10 coordinates and precisely controls all components of the system. Utilizing an advanced programmable logic controller (PLC) or industrial computer, control system 10 uses sensors to collect real-time operational data from various components, such as the height of the lift bracket 1, the position of the forward assembly 2, and the clamping force of the clamping assembly 3. Based on pre-set programs and operator commands, control system 10 rapidly processes this data and issues control signals, precisely regulating the movements of actuators such as the second and third drive members 5, thus achieving automated and intelligent steering knuckle assembly and disassembly operations.
