[0002] Aerial work vehicles refer to special vehicles used to transport workers and equipment to the site and perform aerial work. Wheels are rigid wheels that fix the inner edge of the tire, support the tire, and bear the load together with the tire. The tire, rim, and spoke that are combined together are collectively referred to as wheels. The wheel assembly consists of two major components: wheels and tires. At present, the contact area between the tire and the ground of the shock-absorbing wheels dedicated to aerial work vehicles is mostly fixed.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the aerial work vehicle is used on sandy or rugged roads, the power supply is started to make the electromagnet conduct magnetism to the metal ring, and then the metal ring and the magnetic repulsion of several groups of magnetic blocks push several groups of magnetic blocks outward, and several groups of magnetic blocks drive several groups of connecting plates to expand outward, and then several groups of connecting plates pull several groups of second connecting rods to rotate, so that the crossing angles of several groups of first connecting rods and several groups of second connecting rods are reduced, and at the same time, several groups of axle frames slide to one side on the inner side of several groups of slide rails, and finally several groups of connecting plates drive the middle of the rubber wheel to expand evenly, so that when the aerial work vehicle is on sandy or rugged roads, the shock-absorbing wheel can automatically increase the contact area with the road surface, thereby improving the friction and grip between the wheel and the sandy ground, providing better driving stability, and the larger contact area can reduce the pressure on the soft ground and improve the vehicle's passability.

[0015] 2. Secondly, when the aerial work vehicle successfully passes through the rugged section and drives on the platform section, the power supply is started to make the current flow in the opposite direction, so that the electromagnet drives the metal ring to switch the magnetism, so that the metal ring and the magnetism of several groups of magnetic blocks are attracted to each other, and several groups of magnetic blocks drive several groups of connecting plates to reset, and then several groups of connecting plates drive the middle of the rubber wheel to shrink inward, so that the shock-absorbing wheel can automatically reduce the contact area with the road surface when driving on a flat road. The smaller contact area can make the wheel more sensitive when turning, improve the vehicle's handling, and reduce the vehicle's driving resistance and fuel consumption.

[0016] 3. In addition, when the aerial work vehicle is driving on a rugged and muddy road, the main gear is driven to rotate by starting the motor, and then the meshing sub-gear is rotated, and the five sets of limit grooves are rotated to control the five sets of plug rods to extend outward from the inside of the five sets of slide grooves, so that the arc surface of the five sets of plug rods pushes the five sets of scrapers and five sets of L-shaped rods to rotate, compressing the five sets of torsion springs, and extending and inserting them into the road surface for driving, thereby improving the grip of the shock-absorbing wheels, increasing the friction between the wheels and the ground, avoiding skidding between the wheels and the ground mud, and at the same time dispersing and absorbing vibrations by increasing contact with the ground, thereby achieving the effect of reducing bumps and vibrations.

[0017] 4. Then, when the starting motor drives the five groups of plug rods to be retracted, according to the elastic force of the five groups of torsion springs, the five groups of L-shaped rods and the five groups of scrapers are driven to rotate and reset, so that the five groups of scrapers fit the arc surface of the five groups of plug rods, and the soil attached to the plug rods after the plug rods are inserted into the ground is scraped off, so as to avoid damage to the plug rods caused by soil accumulation. Automatic scraping of soil can reduce dependence on manual labor, saving time and effort.

[0018] 5. Finally, the arc setting at the connection achieves a spring-like effect, which increases the shock absorption effect of the aerial work vehicle during driving, improves the safety and stability of the operation, reduces the impact and vibration of the equipment during operation, thereby reducing the wear and damage of mechanical parts, reducing the vibration and discomfort felt by the operator during work, and improving the comfort of the operator. By setting the reinforcing ring, the wheel strength is increased, the carrying capacity of the aerial work vehicle is improved, the stability is enhanced, and the passability is improved. The shaft ring and the connecting shaft are fixedly connected through six sets of bolts to achieve a detachable structure of the wheel and the shaft, improve the efficiency of repair and maintenance, and reduce the difficulty of repair and maintenance.

[0025] When the aerial work vehicle is used on sandy or rugged roads, the power supply 71 is started to make the electromagnet 72 conduct magnetism to the metal ring 73, and then the metal ring 73 and the magnetic repulsion of the plurality of magnetic blocks 711 push the plurality of magnetic blocks 711 outward, and the plurality of connecting plates 710 are driven to expand outward through the plurality of magnetic blocks 711, and then the plurality of connecting plates 710 pull the plurality of second connecting rods 79 to rotate, so that the crossing angles of the plurality of first connecting rods 78 and the plurality of second connecting rods 79 are reduced, and at the same time, the plurality of shaft frames 712 slide to one side on the inner side of the plurality of slide rails 713, and finally the plurality of connecting plates 710 drive the middle of the rubber wheel 74 to expand evenly, so that when the aerial work vehicle is on sandy or rugged roads, the shock-absorbing wheel can automatically increase the contact area with the road surface, thereby improving the contact between the wheel and the sand.

By setting the reinforcing ring 4, the wheel strength is increased, the carrying capacity of the aerial work vehicle is improved, the stability is enhanced, and the passability is improved. The setting of the shaft ring 3 and the connecting shaft 5 are fixedly connected through six sets of bolts 6 to realize the detachable structure of the wheel and the shaft, improve the efficiency of repair and maintenance, and reduce the difficulty of repair and maintenance.

[0026] The auxiliary mechanism 8 includes a protective cover 81 fixedly arranged at the front side of the connection part 2, a motor 82 is fixedly installed on the inner side of the protective cover 81 near one side, a main gear 83 is fixedly connected to the rear side of the motor 82, a sub-gear 84 is movably arranged on one side of the main gear 83, a fixing ring 85 is movably connected to the rear side of the sub-gear 84, five groups of slide grooves 86 are fixedly connected to the front end of the fixing ring 85, plug rods 87 are slidably arranged on the inner sides of the five groups of slide grooves 86, limiting grooves 88 are provided on the inner side of the sub-gear 84 corresponding to the positions of the five groups of plug rods 87, round shafts 89 are fixedly arranged at the front ends of the five groups of slide grooves 86, L-shaped rods 810 are movably arranged on the outer sides of the five groups of round shafts 89, torsion springs 811 are fixedly connected between the five groups of slide grooves 86 and the five groups of L-shaped rods 810, and scraper strips 812 are fixedly connected to the rear ends of the five groups of L-shaped rods 810.

[0027] The outer side of the protective cover 81 is provided with openings corresponding to the positions of the main gear 83 and the five groups of plug rods 87. The main gear 83 and the sub-gear 84 are meshed, the fixing ring 85 and the shaft ring 3 are fixedly connected, the five groups of plug rods 87 are limitedly slidably arranged on the inner side of the five groups of slide grooves 86, one side of the five groups of plug rods 87 is an arc surface, the five groups of limit grooves 88 are inclined, the five groups of torsion springs 811 are sleeved on the outer side of the five groups of circular shafts 89, and the five groups of scraper strips 812 and the five groups of plug rods 87 are fitted together.

[0028] Secondly, when the aerial work vehicle passes smoothly through the rugged section and drives on the platform section, the current is reversed by starting the power supply 71, so that the electromagnet 72 drives the metal ring 73 to switch the magnetism, so that the metal ring 73 is attracted to the magnetism of several groups of magnetic blocks 711, and several groups of magnetic blocks 711 drive several groups of connecting plates 710 to reset, so that several groups of connecting plates 710 drive the middle of the rubber wheel 74 to retract, so that the shock-absorbing wheel can automatically reduce the contact area with the road surface when on a flat road section. The smaller contact area can make the wheel more sensitive when turning, improve the vehicle's handling, reduce the vehicle's driving resistance and the car's fuel consumption. In addition, when the aerial work vehicle is driving on a rugged and muddy section, the main gear 83 is driven to rotate by starting the motor 82, so that the meshing sub-gear 84 is rotated, and the five groups of limit slots 88 are rotated to control the five groups of plug rods 87 to rotate.

[0029] Working principle: When the aerial work vehicle is used on sandy or rugged roads, the power supply 71 is started to make the electromagnet 72 conduct magnetism to the metal ring 73, and then the metal ring 73 and the magnetic repulsion of the several groups of magnetic blocks 711 push the several groups of magnetic blocks 711 outward, and the several groups of magnetic blocks 711 drive the several groups of connecting plates 710 to expand outward, so that the several groups of connecting plates 710 pull the several groups of second connecting rods 79 to rotate, so that the crossing angles of the several groups of first connecting rods 78 and the several groups of second connecting rods 79 are reduced, and at the same time, the several groups of shaft frames 712 slide to one side on the inner side of the several groups of slide rails 713, and finally the several groups of connecting plates 710 drive the middle of the rubber wheel 74 to expand evenly, so that the aerial work vehicle can be driven on the sand. Or when the road is on a rough or rugged section, the shock-absorbing wheel can automatically increase the contact area with the road surface, thereby improving the friction and grip between the wheel and the sandy ground, providing better driving stability, and the larger contact area can reduce the pressure on the soft ground, improving the vehicle's passability. Secondly, when the aerial work vehicle successfully passes through the rugged section and drives on the platform section, the power supply 71 is started to make the current flow in the opposite direction, so that the electromagnet 72 drives the metal ring 73 to switch the magnetism, so that the metal ring 73 and the magnetism of several groups of magnetic blocks 711 are attracted to each other, and the several groups of magnetic blocks 711 drive the several groups of connecting plates 710 to reset, and then the several groups of connecting plates 710 drive the middle of the rubber wheel 74 to retract, so that the shock-absorbing wheel can automatically The contact area with the road surface is reduced. A smaller contact area can make the wheel more sensitive when turning, improve the vehicle's maneuverability, reduce the vehicle's driving resistance and the car's fuel consumption. In addition, when the aerial work vehicle is driving on a rugged and muddy road, the main gear 83 is driven to rotate by starting the motor 82, so that the meshing sub-gear 84 is rotated, and the five groups of limit grooves 88 are rotated to control the five groups of plug rods 87 to extend outward from the inner side of the five groups of slide grooves 86, so that the arc surface of the five groups of plug rods 87 pushes the five groups of scrapers 812 and five groups of L-shaped rods 810 to rotate, compressing the five groups of torsion springs 811, extending and inserting them into the road surface for driving, thereby improving the grip of the shock-absorbing wheel, increasing the friction between the wheel and the ground, and avoiding the wheel and the ground from stagnating. The mud will slide sideways, and the vibration will be dispersed and absorbed by increasing the contact with the ground, so as to achieve the effect of reducing bumps and vibrations. Then, when the starting motor 82 drives the five groups of plug rods 87 to be retracted, according to the elastic force of the five groups of torsion springs 811, the five groups of L-shaped rods 810 and the five groups of scraping strips 812 are driven to rotate and reset, so that the five groups of scraping strips 812 fit the arc surface of the five groups of plug rods 87, and scrape the attached mud after the plug rods 87 are inserted into the ground, so as to avoid damage to the plug rods 87 caused by mud accumulation, and automatic scraping of mud can reduce dependence on manual labor, save time and effort, and finally, through the arc setting of the connection 2, a spring-like effect is achieved, which increases the shock absorption effect of the aerial work vehicle during driving, improves the safety and stability of the operation,Reduce the impact and vibration of the equipment during operation, thereby reducing the wear and damage of mechanical parts, reducing the vibration and discomfort felt by operators during work, and improving the comfort of operators.
