Among them, aerial work vehicles are widely used due to their convenient transportation, high operating efficiency and low failure rate.

[0003] At present, aerial work is also required in indoor spaces such as large shopping malls, exhibition centers, and airports. For example, repairing lamps, hanging advertisements, and repairing roofs and high-altitude equipment all require aerial work platforms. However, most existing aerial work vehicles are designed for outdoor use, and have the following defects when performing indoor aerial work: (1) Ordinary aerial work vehicles are too large to enter and exit the doorway due to their limited width and height; (2) Generally, aerial work vehicles are equipped with fuel engines as power sources, which can produce noise of up to 85 decibels when working. Excessive noise and exhaust emissions indoors are not conducive to people's comfort and experience of the surrounding environment; (3) Most shopping malls and venues are paved with marble tiles inside and outside. The lower end of the common outriggers is in contact with the ground with iron plates, which are easy to damage or scratch the marble tiles; (4) When ordinary aerial work vehicles are tied to trailers for transportation, they need cranes or forklifts to put them on the trailers, which increases transportation costs and time.

[0035] The embodiment studies the channel dimensions of existing large shopping malls. Generally, large shopping malls are built with 4 to 5 floors, with a floor height of about 4 meters. The general channel door size (height × width) is 3 meters × 1.6 meters, and the width of the shopping mall fire channel is not less than 1.3 meters; the indoor height of the exhibition center is about 5 to 10 meters, and the channel door size (height × width) is 2.8 meters × 2.5 meters; the indoor height of the airport is about 20 meters, and the hall channel door size (height ~ width) is 2.8 meters ~ 4 meters. In order to meet the normal passage of vehicles and the required operating height, the vehicle's retracted size is reduced, and the designed retracted size (length × width × height) is 7.1 × 1.22 × 2.1 meters. The designed maximum operating height is 23 meters, which meets the indoor height of buildings such as general large shopping malls, exhibition centers, and airports. The height in the retracted state is 2.2m and the width is 1.3m.

[0036] The spider car in the embodiment has to pass through a narrow space, and the battery box used has a certain volume, and the battery box has a length, width and height of 610*515*839mm. Therefore, the chassis width is changed to 920mm. The width of the finished vehicle needs to be controlled at 1220mm. The volume of the hydraulic oil tank meets the demand for hydraulic oil of the whole vehicle, and the battery box capacity meets the working time of 2 to 3 hours. The volume of the hydraulic oil tank is minimized to 90 liters, and the dimensions are 457*475*477mm in length, width and height. While ensuring the stability of the whole vehicle lifting operation, the span of the outrigger footboard and the reasonable installation size of the outrigger on the chassis are calculated, and the leg installation hole distance is 1762х712mm. It is used as a driving wheel near the end of the hydraulic oil tank because the oil pipe is short and there is an arm support frame that can be fixed to the upper end of the tire mounting frame. In order to ensure that the tire does not interfere with the chassis during the rotation and steering process, the chassis is cut out at the place where the steering wheel is installed, which is obviously narrower than the structural part where the drive wheel is installed. According to the overall structure, a suitable power battery box is selected, and a lithium battery box with a capacity of 80V and 225Ah is selected, with an overall size of 610*515*839mm in length, width and height. Equipped with a 220V AC motor, it can work for 2 to 3 hours in the event of a power outage and meet the requirements of reducing noise. It effectively solves the emission pollution of traditional fuel engines in indoor environments.

[0037] Ceramic tiles are available in M1 to M4 grades, of which M1 has the lowest compressive strength, which is 0.8 to 1.5 MPa, and M4 has a compressive strength of 4.5 to 6 MPa, which is suitable for large public places, industrial buildings, etc. The current tire width is 190 mm. Taking an ordinary car as an example, the ground length dimension is 100 mm. Taking M1 grade ceramic tiles as an example, it is calculated that it can withstand 0.8*190*100 / 10000=1.52 tons under the current area. In the embodiment, the vehicle mass is 4 tons, and a single tire needs to bear an average load of 1 ton. According to the safety factor of 1.3 times, 1.52 tons>1.3 tons. The design proves that the load-bearing capacity of a single tire meets the requirements and will not crush the ceramic tiles; the use of non-marking tires will not leave rubber scratches or brake marks on the ceramic tiles even during driving, effectively protecting the ceramic tile floor from scratches. The length and width of the nylon slide on the footboard are 630*250mm respectively. Taking M1 grade tiles as an example, it is calculated that it can bear 0.8*630*250 / 10000=12.6 tons under the current area. The design vehicle mass is 4 tons, and a single nylon slide needs to bear an average of 1 ton. According to the safety factor of 1.3 times, 12.6 tons>1.3 tons. The design proves that the load-bearing capacity of a single nylon slide meets the requirements and will not crush the tiles. The nylon slide on the footboard will protect the tile floor from being scratched during operation.

[0038] The commonly used 9.6-meter trucks on the market have a chassis height of 1.3 to 1.5 meters and a cargo compartment width of 2.3 to 2.4 meters. The loading height inside the compartment is 2.5 to 2.7 meters, and the 9.6-meter truck can carry more than 12 tons. When the spider car legs in the embodiment are unfolded and the chassis is raised, the tires are more than 1.5 meters above the ground, the span of the unfolded legs is greater than 2.5 meters, and the components under the chassis do not interfere with the 9.6-meter truck's bucket, and it can smoothly drive under the chassis.

[0039] After the spider car in the utility model is assembled, the following tests are completed in the factory, including but not limited to maneuverability, operating height, vehicle weight, overall dimensions, outrigger span, operating radius, operating action, climbing ability, noise decibel values ​​of the two power sources, height of the tires from the ground when the outriggers are deployed, and whether the trucks simulate interference under the chassis. After being confirmed qualified, a passability test is conducted on the floor with tiles laid in a simulated shopping mall to observe whether the tires leave marks on the tiles or crush the tiles. The operating action, operating radius, height, etc. are tested on the floor with tiles laid to observe whether the tiles under the nylon skateboard are damaged or scratched. After a series of tests, it can be used normally.
