[0002] In the prior art, when cleaning garbage on the road, sanitation workers usually observe the garbage on the road with their naked eyes and then clean it manually, which is very dangerous. In some special sections of roads, such as elevated roads and highways, road maintenance vehicles are generally used while the personnel in the vehicle use special tools to manually clean the garbage on the road. However, some metal parts on the road are relatively small and sometimes cannot be observed by the naked eye. These metal parts are very likely to cause traffic accidents, so they need to be cleaned.

[0003] Some domestic departments have magnets fixed on the arms of road maintenance vehicles. Magnets are permanent magnets that will generate magnetism with nearby ferromagnetic materials, causing interference or damage to electrical components and equipment, especially the equipment at the entrance and exit toll stations of expressways will fail when the device passes by. Moreover, the adsorption range of such devices is relatively limited. Summary of the invention:

The positioning device includes a fixed seat and a locking rod elastically connected to the fixed seat, and the locking rod can be inserted into the guide column.

[0008] In order to make the electromagnet more conspicuous and adapt to nighttime or bad weather, warning lights are respectively fixed to the outer ends of the left electromagnet and the right electromagnet to facilitate observation by other vehicles.

[0009] The present invention also provides a hydraulic control system for the above-mentioned road magnetic suction device, including an oil pump, a motor, a two-way hydraulic lock, a magnetic lifting cylinder control solenoid valve, a magnetic lifting cylinder, a magnetic telescopic cylinder solenoid valve, a magnetic left telescopic cylinder and a magnetic right telescopic cylinder, the motor is connected to the oil pump, the oil pump is respectively connected to the magnetic lifting cylinder control solenoid valve and the magnetic telescopic cylinder solenoid valve, the magnetic lifting cylinder control solenoid valve is connected to the magnetic lifting cylinder through a two-way hydraulic lock, and the magnetic telescopic cylinder solenoid valve is respectively connected to the magnetic left telescopic cylinder and the magnetic right telescopic cylinder through a two-way hydraulic lock.
