Description
Technical Field
[0001] This invention belongs to the field of disassembly device technology, specifically a multifunctional tire disassembly attachment. Background Technology
[0002] Tires are ring-shaped, elastic, load-bearing, and mobile components made of rubber and skeleton materials, mounted on the outside of vehicle rims. They are core, easily damaged parts of construction machinery. The main functions of tires are to bear the weight of the equipment, buffer the impact of the working road surface, provide friction for driving and braking, and ensure the vehicle's movement, steering, starting and stopping operations.
[0003] For example, a car tire changing and mounting machine with publication number CN108482027B includes a horizontal motor reduction mechanism, a movable tire mounting mechanism, a fixed tire mounting mechanism, a tire lever, a lever drive shaft, a power supply, a wireless transmitter, and a wireless receiver. The motor reduction mechanism has an opening in the middle of the right end of its housing. A sleeve is installed on the upper part of the side end of the opening. A bearing is installed at each of the upper and lower ends of the sleeve. The side end of the sleeve has multiple threaded openings, two of which each have a screw screwed into them. The lower parts of the movable tire mounting mechanism, the fixed tire mounting mechanism, and the lever drive shaft are fitted inside the inner rings of the two bearings inside the sleeve. The left end of the tire lever is placed on the upper end of the lever drive shaft. The wireless transmitter is carried by the user. The power supply and the wireless receiver are installed in a component box. The power supply, the wireless receiver, and the motor reduction mechanism are connected by wires. This invention facilitates tire changing and mounting.
[0004] While the above solutions facilitate tire removal and installation, current tire removal and installation methods mostly rely on manual labor and forklift assistance. There is a lack of dedicated integrated hydraulic removal and installation tools. The operation process requires manual assistance in handling and manually rotating the tire for alignment. At the same time, operators need to adjust the position and posture of the forklift multiple times to complete the alignment of the bolt holes. The overall removal and installation process is cumbersome and redundant. This not only significantly increases the time spent on tire removal and installation but also greatly consumes the physical strength of maintenance personnel. It has the industry pain points of high manual labor intensity and low overall efficiency of tire maintenance operations, making it difficult to meet the high-frequency tire maintenance and replacement needs of ports. Summary of the Invention

A left clamping plate is fixedly connected between the two left clamping arms located on the same side and arranged vertically opposite each other. A right clamping plate is fixedly connected between the two right clamping arms located on the other side and arranged vertically opposite each other. The left clamping plate and right clamping plate are respectively externally connected to tilting hydraulic cylinders. The tilting hydraulic cylinders are hinged and fixed at both sides of the main mounting panel bracket assembly. The rotating assembly includes a slewing support ring disposed at the end of the main mounting panel bracket assembly near the maintenance forklift. One end of the slewing support ring is provided with a hydraulic slewing drive motor. A tilting plate is hinged and fixed at the end of the tilting cylinder away from the main mounting panel bracket assembly. A tilting connecting plate is disposed at the end of the tilting plate away from the tilting cylinder. The two tilting connecting plates are respectively assembled with the left clamping plate and the right clamping plate. A slewing valve fixing plate is disposed at one end of the main mounting panel bracket assembly.
[0007] Preferably, oil pipe fixing plates are respectively installed on both sides of the upper end of the main mounting panel bracket assembly for organizing the hydraulic pipes of the restraint equipment.
[0008] Preferably, a valve body bracket is fixedly connected to the upper middle part of the main mounting panel bracket assembly for fixing the hydraulic valve group.
[0009] Preferably, the hinge points of the tilting cylinder and the main mounting panel bracket assembly are interspersed with pin three, and the hinge points of the two sets of tilting plates and tilting connecting plates are interspersed with pin one and pin two, respectively.
[0010] Preferably, one side of each of the first pin, second pin, and third pin is fixedly connected with a shaft cover plate for limiting and protecting the moving parts.
[0011] Preferably, limit sleeves are provided on the outside of pin one, pin two and pin three to limit the displacement and swing clearance of the components.
[0012] Preferably, the hydraulic cylinder assembly is connected to the left and right clamping arms via a transmission, and is used to control the opening and closing of the left and right clamping plates and their horizontal movement.
[0013] Preferably, the left and right clamps are respectively fixedly connected to a plurality of anti-slip and wear-resistant protrusions at their close ends, and the plurality of anti-slip and wear-resistant protrusions are arranged vertically and equidistantly.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the structural cooperation of a clamping arm structure, a hydraulic cylinder assembly, a flipping mechanism, a rotary support, and a hydraulic rotary drive motor, utilizes a hydraulic drive to achieve automatic opening and closing of the clamping arm, horizontal lateral movement, and overall tire flipping and multi-angle rotation adjustment. This replaces the traditional manual handling and manual rotation for hole alignment, simplifies the tedious tire disassembly and assembly process, significantly shortens the tire disassembly and assembly operation time, and effectively solves the problems of high labor intensity and low work efficiency in traditional tire repair. This invention utilizes a structure that combines anti-slip and wear-resistant raised ribs with a limiting sleeve, pin, and shaft cover plate. The anti-slip structure increases clamping friction, and the pin limit eliminates the wobbling gap of the mechanism, ensuring stable locking of heavy-duty tires throughout the process. This prevents tire slippage and displacement during operation, while also reducing direct contact between operators and heavy-duty tires, effectively eliminating safety hazards during tire installation and removal, and improving the alignment accuracy of tire bolt holes. This invention, through the combination of an adjustable clamping mechanism, a standardized hydraulic connection structure, and a towable connecting frame structure, utilizes adjustable clamping arms to adapt to engineering machinery tires of different diameters and specifications. It leverages the forklift's native hydraulic system for power and employs a detachable installation structure, resulting in enhanced equipment adaptability and versatility. Installation and disassembly are convenient and do not damage or affect the original operating performance of the forklift, thus meeting the routine maintenance needs of tires for various types of mobile engineering machinery in ports.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] like Figures 1 to 6 As shown, the present invention provides a multifunctional tire removal attachment, including a tire removal mechanism that is assembled with a repair forklift, and further including: a clamping assembly and a rotating assembly. The clamping assembly includes a main mounting panel bracket assembly 1. The end face of the main mounting panel bracket assembly 1 is respectively provided with a second hook 2, a central pad 9, and a first hook 7. Pads 2 10 and 1 8 are respectively fixedly connected to the side of the second hook 2 and the first hook 7 away from the main mounting panel bracket assembly 1. The upper guide groove 5 and the lower guide groove 6 are respectively fixedly connected to the upper and lower sides of the main mounting panel bracket assembly 1. Two sets of left clamping arms 3 and right clamping arms 4 are respectively provided in the upper guide groove 5 and the lower guide groove 6. There are two left clamping arms 3 and two right clamping arms 4. The left clamping arms 3 and the right clamping arms 4 are respectively connected to the external hydraulic cylinder assembly 14. The two left clamping arms 3 located on the same side and arranged vertically opposite each other are fixedly connected to the left clamping plate 12. The two right clamping arms 4 located on the other side and arranged vertically opposite each other are fixedly connected to the right clamping plate 13. The left clamping plate 12 and the right clamping plate 13 are respectively connected to the external tilting hydraulic cylinder 18. The tilting hydraulic cylinder 18 is hinged and fixed on both sides of the main mounting panel bracket assembly 1.
[0021] The above-mentioned solution employs a slewing support frame ring 26, which is manufactured using an integral cast steel process. This results in high overall coaxiality and strong load-bearing stability, enabling it to stably support the entire front-end clamping mechanism and heavy tire load without eccentric swaying or deformation under stress. The hydraulic slewing drive motor 15 serves as the rotational power actuator, precisely meshing with the slewing support frame ring 26 for transmission. This ensures uniform power transmission without jamming, allowing for smooth, stepless, and fine-tuned rotation of the clamping assembly. This structure utilizes an integral cast steel design to replace the traditional spliced support structure, addressing the issues of insufficient load-bearing capacity and large coaxiality deviation in traditional support structures. This ensures uniform force distribution during the rotation of heavy tires, thereby effectively improving the accuracy of tire alignment and operational stability.
[0022] like Figures 1 to 6 As shown, the rotating assembly includes a slewing support ring 26 disposed at the end of the main mounting panel bracket assembly 1 near the maintenance forklift. A hydraulic slewing drive motor 15 is disposed at one end of the slewing support ring 26. A tilting cylinder 18 is hinged to a tilting plate 19 at the end away from the main mounting panel bracket assembly 1. A tilting connecting plate 20 is disposed at the end of the tilting plate 19 away from the tilting cylinder 18. The two tilting connecting plates 20 are respectively assembled with the left clamping plate 12 and the right clamping plate 13. A slewing valve fixing plate 11 is disposed at one end of the main mounting panel bracket assembly 1.
[0023] The above-mentioned scheme adopts an integrated ear plate structure for both the flipping plate 19 and the flipping connecting plate 20, with no weak points in the welding splicing. The overall tensile and torque resistance is excellent. The purpose of this structure is to eliminate the stress concentration and weld cracking hazards of the welded structure, and to solve the problem of easy deformation and damage of traditional transmission connecting parts under stress. This ensures the stable transmission of flipping power, thereby continuously adapting to the heavy-duty tire heavy load flipping operation conditions and extending the overall service life of the equipment.
[0024] like Figures 1 to 6As shown, oil pipe fixing plates 16 are respectively mounted on both sides of the upper end of the main mounting panel bracket assembly 1 for organizing and binding the hydraulic pipes of the equipment. A valve body bracket 17 is fixedly connected to the middle of the upper end of the main mounting panel bracket assembly 1 for fixing the hydraulic valve group. A pin 24 is inserted at the hinge point of the tilting cylinder 18 and the main mounting panel bracket assembly 1. Pins 21 and 23 are respectively inserted at the hinge points of the two sets of tilting plates 19 and tilting connecting plates 20. A shaft cover plate 25 is fixedly connected to one side of pins 21, 23 and 24 for limiting and protecting the moving parts. Limit sleeves 22 are respectively provided on the outside of pins 21, 23 and 24. The hydraulic cylinder assembly 14 is used to limit the displacement and swing clearance of the components. It is connected to the left clamping arm 3 and the right clamping arm 4 for transmission. It is used to control the opening and closing of the left clamping plate 12 and the right clamping plate 13 and the horizontal side movement. The left clamping plate 12 and the right clamping plate 13 are respectively fixedly connected to a number of anti-slip and wear-resistant protrusions 27 at their close ends. The number of anti-slip and wear-resistant protrusions 27 are arranged vertically and equally. The left clamping arm 3 and the right clamping arm 4 adopt an arc-shaped fitting structure. The arc surface curvature matches the outer circle contour of the engineering tire to increase the contact area with the tire body. The slewing support frame ring 26 is a ring-shaped disc bearing shape. It is coaxially mounted on the rear end of the main mounting panel bracket assembly 1 and meshes with the power output end of the hydraulic slewing drive motor 15.
[0025] The above scheme is adopted as follows: each pin component adopts a solid high-strength shaft body with heat treatment, which has high overall hardness, wear resistance and bending resistance. The matching limit sleeve 22 adopts a high wear-resistant copper sleeve structure, which can fill the hinge fit gap and eliminate the swing play of the mechanism. The shaft cover plate 25 adopts a bolt-tightening sealing and protection structure to realize the axial limit of the pin and the dust and water protection of the end face, effectively improving the service life and motion accuracy of the hinge part. The valve body bracket 17 adopts a thickened steel plate bending and forming structure, which has excellent shock resistance and deformation resistance, and can provide stable installation support for multi-way hydraulic valve group, eliminating the problem of valve body vibration and displacement during operation. The oil pipe fixing plate 16 adopts a segmented snap-locking structure, which can layer and classify all hydraulic pipelines to avoid pipeline cross compression and friction damage, while limiting pipeline operation pulling displacement and ensuring the sealing stability of hydraulic oil circuit.
[0026] Furthermore, the entire machine in this solution is equipped with a visual electrical auxiliary system, which uses a high-definition waterproof industrial camera, an industrial explosion-proof display screen, and a dedicated video storage host. The camera element and the display element are electrically connected, which can collect the operation alignment image in real time and retain the operation data. All electrical components are port industrial grade waterproof and dustproof models, which can be adapted to high dust and high humidity operation environments for a long time.
[0027] Working principle and usage process of this invention: The forklift mast and fork carriage can be detachably assembled with the maintenance forklift using a tow-mounted connection structure with bolts and positioning pins. The assembly structure adopts a standardized interface design, which will not interfere with the original operation function of the forklift. The forklift's own hydraulic system serves as the sole power source for the entire machine. The hydraulic circuit is matched with a hydraulic valve group, and quick connectors are used at the hydraulic pipeline connections to achieve sealed connection. The valve body bracket 17 fixes the hydraulic valve group of the entire machine, ensuring the stable installation of the hydraulic control components. The oil pipe fixing plate 16 neatly binds all hydraulic pipelines to avoid problems such as pulling, bending and leakage of pipelines during operation.
[0028] When the equipment starts up, the hydraulic system first supplies power to the cylinder assembly 14. The two ends of the cylinder assembly 14 are respectively connected to the left clamping arm 3 and the right clamping arm 4, driving the left and right clamping arms to open and close along the upper guide groove 5 and the lower guide groove 6, thereby causing the left clamping plate 12 and the right clamping plate 13 to move towards or away from each other. The cylinder assembly 14 is used as the clamping power source to solve the problems of low efficiency and high labor intensity associated with traditional manual clamping and repeated fine-tuning with forklifts, thus achieving automated clamping and alignment adjustment. In the specific operation process, during the synchronous retraction of the cylinder assembly 14, the left clamping arm 3 and the right clamping arm 4 slide relative to each other along the upper guide groove 5 and the lower guide groove 6, completing the clamping action of the large construction machinery tires. During the synchronous extension of the hydraulic cylinder assembly 14, the two sets of clamping arms slide and separate in opposite directions, completing the tire release process. When the hydraulic cylinder assembly 14 operates in a differentiated telescopic manner, it can drive the clamping arm assembly to achieve horizontal lateral adjustment to adapt to different tire alignment deviations. The clamping arm opening and closing adjustment range can adapt to various specifications of engineering tires, thereby effectively covering the tire disassembly and assembly needs of various types of engineering machinery in the port and improving the equipment's adaptability. When the hydraulic cylinder assembly 14 operates in a differentiated telescopic manner, it can drive the clamping arm assembly to achieve a maximum horizontal lateral adjustment of 300mm to adapt to different tire alignment deviations. The clamping arm opening and closing adjustment range covers 800mm to 2000mm and can adapt to engineering tires with diameters from 900mm to 1800mm.
[0029] Multiple anti-slip and wear-resistant protruding ribs 27 are arranged vertically and equidistantly on the inner sides of the left clamping plate 12 and the right clamping plate 13. Together with the arc-shaped fitting structure of the left clamping arm 3 and the right clamping arm 4, this solves the problem of heavy tires being heavy and having a smooth surface, making them prone to slippage and misalignment during the clamping process. This improves the clamping friction and fit, effectively preventing heavy tires from slipping or shifting during clamping and displacement. As a result, the overall structure can meet the load-bearing capacity requirements of heavy tires weighing 800 kg or more, ensuring clamping stability under heavy-load operating conditions.
[0030] After the tire is clamped and fixed, the hydraulic system supplies power to the two-sided tilting cylinders 18. The tilting cylinders 18 are hinged to both sides of the main mounting panel bracket assembly 1 via pin 3 24. When the piston rod of the tilting cylinder 18 extends and retracts, it drives the tilting connecting plate 20 to swing the tilting plate 19. The tilting plate 19 is docked and fixed with the rear rotary support ring 26, which can drive the overall clamped tire to complete ±180-degree all-round front and rear tilting adjustment, adapting to the tire disassembly and assembly posture adjustment requirements under different working conditions. After the tilting posture adjustment is completed, the rotary valve fixing plate 11 fixes the rotary control valve body to stabilize the hydraulic control logic. The hydraulic rotary drive motor 15 receives hydraulic power and outputs torque to drive the rotary support ring 26 to rotate coaxially. The rotary support ring 26 serves as a ring-shaped disc bearing base, driving the front-end main mounting panel bracket assembly 1 and the overall clamping assembly to rotate synchronously, which can realize ±30-degree vertical rotation and ±10-degree horizontal fine adjustment rotation of the tire, accurately correcting the alignment deviation between the tire steel rim screw hole and the wheel hub screw, and reducing the manual repeated adjustment process.
[0031] All hinged movement points of the machine are equipped with dedicated positioning and protection structures. The hinge positions of the flipping plate 19 and the flipping connecting plate 20 are respectively inserted with pin 1 21 and pin 23. The hinge position of the flipping cylinder 18 and the main mounting panel bracket assembly 1 is inserted with pin 3 24. The ends of the three sets of pins are uniformly equipped with shaft cover plates 25 to achieve axial limit protection. Limiting sleeves 22 are respectively fitted on the outside of the three sets of pins to fill the assembly gaps of the components, limit the displacement and swing amplitude of the moving parts during operation, and avoid the shaking, jamming, and loosening of the various moving mechanisms. This ensures the stability and accuracy of the entire process of clamping, lateral movement, flipping, and rotation of the machine.
