Description

Technical Field

[0001] This utility model relates to a tooling for a wheel hub suspension assembly of a mining dump truck, belonging to the technical field of suspension cylinder transport superstructure. Background Technology

[0002] With the increasing size of mining dump trucks, the hydraulic cylinder structures used in their suspension systems are becoming increasingly heavy-duty and large. Current mainstream installation processes require the front suspension cylinders to be pre-assembled into the front wheel hub assembly before the integrated unit is installed onto the chassis. Due to the irregular geometry of the front wheel hub, the center of gravity of the integrated unit deviates significantly from its geometric center. This inherent characteristic makes it prone to center of gravity shift during transportation. When the heavy-duty suspension cylinder is assembled to the designated position on the wheel hub according to process requirements, the actual center of gravity of the entire integrated module will deviate significantly from the component's geometric center, resulting in a significant mass eccentricity. This inherent structural defect leads to a non-uniform force distribution when the integrated unit is placed horizontally, preventing stable contact at the bottom support surface.

[0003] During the superstructure operation, insufficient static stability poses a risk of tipping over, severely restricting shipping efficiency and assembly safety. When the hoisting equipment moves the integrated module to the chassis installation position, the module, while suspended, experiences continuous swaying due to imbalance of the center of gravity, making it difficult for operators to accurately control its spatial posture. During the adjustment or positioning calibration of the hoisting rigging, the module needs to be briefly placed on a temporary support frame. At this time, because the center of gravity deviates from the center of the support surface, the module is prone to lateral slippage or even tipping over, which not only easily damages the precision hydraulic cylinder sealing system but also poses a safety threat to on-site workers. Summary of the Invention

[0004] Purpose of the invention: To solve the above-mentioned technical problems, this utility model provides a tooling for a wheel hub suspension assembly of a mining dump truck. This device improves the support stability and overall rigidity of the suspension cylinder and wheel hub integrated module by setting a first support component and a second support component in a square frame.

[0005] Technical Solution: A tooling for a mining dump truck wheel hub suspension assembly includes a square frame, a first support component and a second support component disposed inside the square frame. The square frame is a fully enclosed structure. The top surface of the square frame has a placement opening, and the side surface along the upper loading direction has an upper loading opening. The first support component and the second support component are arranged sequentially along the upper loading direction. The first support component abuts against the arc portion at the front end of the wheel hub, and the second support component abuts against the bottom plane of the wheel hub vertical plate near the connection between the wheel hub and the suspension cylinder. The axis of the wheel hub is in the same direction as the upper loading direction. A rectangular tube for forklift transportation is connected to the bottom surface of the square frame, and the rectangular tube is arranged along the upper loading direction.

[0006] This invention improves the transport and hoisting stability of the integrated module of the suspension cylinder and wheel hub by employing a square frame, a first support component, and a second support component, and by providing a placement port, a loading port, and a rectangular tube connected to the bottom surface along the loading direction. This effectively prevents uneven force distribution, swaying, or overturning risks caused by center of gravity shift, thereby improving shipping efficiency and assembly safety. The integrated module of the suspension cylinder and wheel hub is hoisted onto the first and second support components through the placement port on the top surface. Then, a forklift tooth is inserted into the bottom rectangular tube for transport. During loading, the forklift tooth is raised to the frame position, and the loading port is aligned with the frame to achieve the loading of the integrated module.

[0007] In a preferred embodiment, to improve support accuracy and center of gravity control, the first support component includes an arc-shaped support base and a first support frame, and the second support component includes a planar support base and a second support frame. The first support frame is connected to the interior of the square frame and to the bottom of the arc-shaped support base, and the second support frame is connected to the interior of the square frame and to the bottom of the planar support base.

[0008] By using an arc support seat that abuts against the arc part at the front end of the wheel hub, and a flat support seat that abuts against the bottom plane of the wheel hub vertical plate, customized support is achieved for the irregular geometric features of the wheel hub, ensuring uniform force distribution and reducing mass eccentricity.

[0009] In a preferred embodiment, to improve the structural strength and rigidity of the arc support base, the first support frame includes a first support rod, a second support rod, a third support rod, and a fourth support rod. One end of the first support rod is connected to the side of the square frame parallel to the upper assembly direction, and the other end is connected to the arc support base. The second support rod is symmetrically arranged with the diameter of the arc support base in the vertical direction as its center line. The third support rod is arranged in the vertical direction, and its two ends are respectively connected to the bottom surface of the square frame and the bottom of the arc support base. The two ends of the fourth support rod are respectively connected to the bottom surface of the square frame and the outer wall of the third support rod.

[0010] The system employs a layout of first support rod, second support rod, third support rod, and fourth support rod, with one end connected to the side of the frame and the other end connected to the arc support base. Symmetrical and vertical supports are also provided to achieve a stable fixation of the arc-shaped part at the front end of the wheel hub, preventing deformation or displacement during transportation.

[0011] In a preferred embodiment, to address the difficulty of directly welding support rods to the bottom of the arc-shaped support base, the first support frame further includes a fifth support rod. The two ends of the fifth support rod are respectively connected to the first support rod and the second support rod. The bottom of the arc-shaped support base is connected to the fifth support rod, and the third support rod is connected to the bottom of the arc-shaped support base through the fifth support rod.

[0012] The fifth support rod connects the first and second support rods at both ends, and connects to the bottom of the arc support base in the middle, achieving a more manufacturing-friendly and reliable connection method, avoiding welding defects, and ensuring the long-term durability of the first support component.

[0013] In a preferred embodiment, to improve the balance and symmetry of the overall tooling, the second support frame has the same structure as the first support frame, and the first support frame and the second support frame are symmetrically arranged along the direction perpendicular to the upper assembly.

[0014] The second support frame is identical in structure to the first support frame and is symmetrically arranged along the direction perpendicular to the upper structure, so as to achieve a central distribution of the center of gravity, offset the eccentricity caused by the irregular shape of the wheel hub, and reduce the risk of hoisting sway.

[0015] In a preferred embodiment, to further improve the balance and symmetry of the overall tooling, the planar support seat is also provided with an adjusting bolt, which abuts against the bottom plane of the hub rib plate, and the bottom plane of the hub rib plate is higher than the bottom plane of the hub vertical plate.

[0016] By using adjusting bolts to abut against the bottom plane of the wheel hub rib, the transportation risks of only abutting against the wheel hub vertical plate are mitigated, the bottom plane support of the wheel hub rib is increased, and the height deviation caused by different rib processing techniques can be accommodated by adjusting the bolts, thus offsetting the eccentricity caused by the irregular shape of the wheel hub.

[0017] In a preferred embodiment, to improve the wheel hub's fixation and force balance, a first strap for fixing the front end of the wheel hub and a second strap for fixing the rear end of the wheel hub are further included. The two ends of the first strap are detachably connected to the two sides of the square frame parallel to the superstructure direction, and the two ends of the second strap are detachably connected to the two sides of the square frame parallel to the superstructure direction.

[0018] The first strap secures the front end of the wheel hub, and the second strap secures the rear end of the wheel hub. They are detachably connected to both sides of the square frame to achieve a firm constraint on the module during transportation and hoisting, reduce swaying and slippage, and protect the integrated module and personnel safety.

[0019] In a preferred embodiment, to improve the flexibility and attitude control of the hoisting operation, hoisting holes are also provided on both sides of the square frame parallel to the upper loading direction.

[0020] The system employs lifting holes on both sides of a square frame parallel to the direction of the superstructure to achieve multi-point assisted positioning, which facilitates operators to accurately adjust the spatial posture of the module and suppresses continuous swaying in the suspended state.

[0021] In a preferred embodiment, to improve the overall load-bearing capacity and deformation resistance of the tooling, the sides and bottom of the square frame are provided with reinforcing square tubes.

[0022] By incorporating reinforcing square tubes on the sides and bottom of the square frame, structural rigidity is enhanced, supporting the weight of the integrated module and preventing support failure caused by frame deformation during transportation or when stationary.

[0023] In a preferred embodiment, to prevent interference with the vehicle frame and to facilitate the operation of the superstructure, the reinforcing square tubes on the side of the square frame with the superstructure opening are shaped like an inverted V.

[0024] The reinforcing square tubes on the side of the upper body opening are arranged in an inverted V-shape to avoid the vehicle frame structure during installation, enabling unobstructed and rapid docking and improving assembly efficiency and safety.

[0025] Beneficial effects: This utility model improves the support stability and overall rigidity of the suspension cylinder and wheel hub integrated module by setting a fully enclosed square frame structure and setting first and second support components inside it to adapt to the front arc part of the wheel hub and the rear bottom plane, respectively. It also improves the problem of severe center of gravity offset caused by the irregular geometry of the wheel hub, so that the integrated module is evenly distributed in terms of force during transportation and stationary placement, effectively preventing side slippage and overturning. At the same time, the rectangular tube set at the bottom facilitates forklift transportation, and the side lifting holes enable multi-point lifting, significantly enhancing the attitude controllability in the suspended state and suppressing swaying. It effectively solves the risk of slippage of the integrated module on the temporary support frame due to center of gravity offset, protects the cylinder from damage, and improves operational safety. By setting adjustable bolts to compensate for wheel hub casting tolerances, inverted V-shaped reinforcing ribs to avoid interference with the vehicle frame, and detachable straps to strengthen the fixation, it can meet the stringent requirements of safe, efficient, and precise transportation, lifting, and upper body docking of heavy-duty suspension cylinder-wheel hub integrated modules for large mining dump trucks.

[0036] like Figures 1-6As shown, a tooling for a mining dump truck wheel hub suspension assembly includes a square frame 1, a first support component 2 and a second support component 3 disposed inside the square frame 1. The square frame 1 is a fully enclosed structure. The top surface of the square frame 1 is provided with a placement opening 4, and the side surface along the upper loading direction is provided with an upper loading opening 5.

The axis of the wheel hub 6 is in the same direction as the upper loading direction. The bottom surface of the square frame 1 is connected to a rectangular tube 7 for forklift transportation, and the rectangular tube 7 is arranged along the upper loading direction.

[0037] By employing a square frame 1, a first support component 2, and a second support component 3, and by providing a placement port 4, a superstructure port 5, and a rectangular tube 7 connected to the bottom along the superstructure direction, the transportation and hoisting stability of the integrated module of the suspension cylinder 12 and the wheel hub 6 is improved. This effectively prevents the risk of uneven force, swaying, or overturning caused by center of gravity shift, thereby improving shipping efficiency and assembly safety. The integrated module of the suspension cylinder 12 and the wheel hub 6 is hoisted onto the first support component 2 and the second support component 3 through the placement port 4 on the top surface. Then, a forklift tooth is inserted into the bottom rectangular tube 7 for transport. During superstructure loading, the forklift tooth is raised to the frame position, and the superstructure port 5 is aligned with the frame to achieve superstructure loading of the integrated module.

[0038] To improve support accuracy and center of gravity control, the first support component 2 includes an arc support base 21 and a first support frame 22, and the second support component 3 includes a flat support base 31 and a second support frame 32. The first support frame 22 is connected to the inside of the square frame 1 and to the bottom of the arc support base 21, and the second support frame 32 is connected to the inside of the square frame 1 and to the bottom of the flat support base 31.

[0039] By using an arc support seat 21 to abut against the arc portion 61 at the front end of the hub 6, and a flat support seat 31 to abut against the bottom plane of the hub vertical plate 62, customized support is achieved for the irregular geometric features of the hub 6, ensuring uniform force distribution and reducing mass eccentricity.

[0040] To improve the structural strength and rigidity of the arc support base 21, the first support frame 22 includes a first support rod 221, a second support rod 222, a third support rod 223, and a fourth support rod 224. One end of the first support rod 221 is connected to the side of the square frame 1 parallel to the upper mounting direction, and the other end is connected to the arc support base 21. The second support rod 222 is symmetrically arranged with the diameter of the arc support base 21 in the vertical direction as the center line. The third support rod 223 is arranged in the vertical direction, and its two ends are connected to the bottom surface of the square frame 1 and the bottom of the arc support base 21, respectively. The two ends of the fourth support rod 224 are connected to the bottom surface of the square frame 1 and the outer wall of the third support rod 223, respectively.

[0041] The arrangement of the first support rod 221, the second support rod 222, the third support rod 223 and the fourth support rod 224, with one end connected to the side of the frame and the other end connected to the arc support seat 21, and symmetrical and vertical supports are provided to achieve a stable fixation of the arc part 61 at the front end of the wheel hub 6, preventing deformation or displacement during transportation.

[0042] To address the difficulty of directly welding support rods to the bottom of the arc support base 21, the first support frame 22 further includes a fifth support rod 225. The two ends of the fifth support rod 225 are respectively connected to the first support rod 221 and the second support rod 222. The bottom of the arc support base 21 is connected to the fifth support rod 225. The third support rod 223 is connected to the bottom of the arc support base 21 through the fifth support rod 225.

[0043] The fifth support rod 225 is used to connect the first support rod 221 and the second support rod 222 at both ends, and the middle part is connected to the bottom of the arc support seat 21, which achieves a more easy-to-manufacture and reliable connection method, avoids welding defects, and ensures the long-term durability of the first support component 2.

[0044] To improve the overall balance and symmetry of the tooling, the second support frame 32 has the same structure as the first support frame 22, and the first support frame 22 and the second support frame 32 are symmetrically arranged along the direction perpendicular to the upper assembly.

[0045] The second support frame 32 is structurally identical to the first support frame 22 and is symmetrically arranged along the direction perpendicular to the upper structure, thereby achieving a centrally distributed center of gravity, offsetting the eccentricity caused by the irregular shape of the wheel hub 6, and reducing the risk of hoisting sway. Example 1

[0046] The second support frame 32 includes a sixth support rod 321, a seventh support rod 322, an eighth support rod 323, and a ninth support rod 324. One end of the sixth support rod 321 is connected to the side of the square frame 1 parallel to the upper mounting direction, and the other end is connected to the planar support base 31. The seventh support rod 322 is symmetrically arranged with the vertical center line of the planar support base 31 as the center of symmetry. The eighth support rod 323 is arranged in the vertical direction, and its two ends are respectively connected to the bottom surface of the square frame 1 and the bottom of the planar support base 31. The two ends of the ninth support rod 324 are respectively connected to the bottom surface of the square frame 1 and the outer wall of the eighth support rod 323.

[0047] To further improve the balance and symmetry of the overall tooling, the planar support 31 is also provided with an adjusting bolt 311, which abuts against the bottom plane of the hub rib 63, and the bottom plane of the hub rib 63 is higher than the bottom plane of the hub vertical plate 62.

[0048] The adjustment bolt 311 is used to abut against the bottom plane of the hub rib 63, which makes up for the transportation risk of only abutting against the hub vertical plate 62, increases the support of the bottom plane of the hub rib 63, and at the same time, the adjustment bolt 311 can meet the height deviation caused by different rib processing technology, and offset the eccentricity caused by the irregular shape of the hub 6.

[0049] To improve the stability and force balance of the wheel hub 6, a first strap 8 for fixing the front end of the wheel hub 6 and a second strap 9 for fixing the rear end of the wheel hub 6 are also included. The two ends of the first strap 8 are detachably connected to the two sides of the square frame 1 parallel to the superstructure direction, and the two ends of the second strap 9 are detachably connected to the two sides of the square frame 1 parallel to the superstructure direction.

[0050] The first strap 8 is used to fix the front end of the wheel hub 6 and the second strap 9 is used to fix the rear end of the wheel hub 6. They are detachably connected to the two sides of the square frame 1 to achieve a firm constraint on the module during transportation and hoisting, reduce swaying and slippage, and protect the integrated module and personnel safety.

[0051] To improve the flexibility and attitude control of the hoisting operation, hoisting holes 10 are provided on both sides of the square frame 1 parallel to the upper construction direction.

[0052] The square frame 1 with lifting holes 10 on both sides parallel to the direction of the upper structure is used to achieve multi-point assisted positioning, which makes it easier for operators to accurately adjust the spatial posture of the module and suppress continuous swaying in the suspended state.

[0053] To improve the overall load-bearing capacity and deformation resistance of the tooling, the square frame 1 is provided with reinforcing square tubes 11 on both the sides and bottom.

[0054] Reinforcing square tubes 11 are installed on the sides and bottom of the square frame 1 to enhance structural rigidity, support the weight of the integrated module, and prevent support failure caused by frame deformation during transportation or static placement. Example 2

[0055] To improve the support effect of the first support frame 22 and the second support frame 32, the reinforcing square tubes 11 on the two sides of the square frame 1 parallel to the upper loading direction are two mutually perpendicular reinforcing square tubes 11. The first support rod 221, the second support rod 222, the sixth support rod 321, and the seventh support rod 322 are all connected to the horizontal reinforcing square tubes 11 on the two sides. The reinforcing square tubes 11 on the bottom surface of the square frame 1 are also two mutually perpendicular reinforcing square tubes 11. The third support rod 223, the fourth support rod 224, the eighth support rod 323, and the ninth support rod 324 are all connected to the reinforcing square tubes 11 arranged along the upper loading direction on the bottom surface. Example 3

[0056] To facilitate the installation of the first strap 8 and the second strap 9, both ends of the first strap 8 and the second strap 9 are detachably connected to the horizontal reinforcing square tubes 11 on both sides of the square frame 1 parallel to the upper mounting direction. Example 4

[0057] In order to make the first support frame 22 and the second support frame 32 more stable under force, the horizontal reinforcing square tubes 11 on both sides of the square frame 1 parallel to the upper loading direction are higher than the reinforcing square tubes 11 on the bottom surface. Example 5

[0058] To facilitate the installation of the rectangular tube 7 for forklift transport, a space is left between the bottom surface of the square frame 1 and the ground for the installation of the rectangular tube 7.

[0059] To prevent interference with the vehicle frame and facilitate the superstructure operation, the reinforcing square tube 11 on the side of the superstructure opening 5 of the square frame 1 is arranged in an inverted V-shape. By arranging the reinforcing square tube 11 on the side of the superstructure opening 5 in an inverted V-shape, the installation avoids the vehicle frame structure, achieving unobstructed and rapid docking, and improving assembly efficiency and safety.
