Description

Technical Field

[0001] The invention relates to a special electric roller and a control method thereof, belonging to the technical field of engineering machinery. Background Art

[0002] Compared with rollers driven by internal combustion engines, electric rollers powered by electricity have many advantages, which can greatly reduce energy consumption and are more environmentally friendly, such as no exhaust emissions and fuel transportation. There are not many products in the field of engineering machinery that use electric energy to drive, and most of them use on-board batteries to drive operations. Limited by the battery's energy storage density, its endurance and service life need to be tested by the market. Electric rollers on the market have not been put into use in batches, and their prices are much higher than those of the same diesel equipment. Electric rollers generally use lithium batteries as energy storage elements. Simply increasing the capacity of on-board batteries is difficult to solve the problem of increasing endurance solutions, because the increase in battery capacity and the sharp increase in battery volume will bring difficulties to the design of the entire roller. Such as increased requirements for battery installation and fixation, increased costs, and increased battery charging time.

[0003] For example, when a special roller used for training is provided to drivers for training, the noise generated by the repeated use of oil-driven rollers is too loud and the exhaust emissions are serious, which greatly affects the environment; when using existing electric-driven rollers, repeated use of electric-driven rollers for a long time is prone to battery loss and the replacement cost is too high. During driving training, due to different operating levels and learning abilities of drivers, dangerous driving situations of varying degrees are prone to occur. Or when used in specific engineering sections, the long-term use of existing oil-consuming or electric-driven rollers has a greater impact on the environment or the roller's own battery pack.

[0022] The hydraulic system 5 is connected to the steering pump 72 in the steering system 7 through the oil pump motor 51 to provide a driving medium for steering. The oil pump motor 51 and the drive motor 22 controlled by the drive motor controller 21 are connected through the brake pump 52 to provide a driving medium for operation. The oil pump motor 51 also provides a brake opening medium for the brake of the wheel-side reducer arranged inside the steel wheel 34. The wheel-side reducer is usually installed near the steel wheel 34. Its function is to reduce the high-speed output of the drive motor 22 and increase the torque to meet the demand for high torque when the vehicle is traveling at a low speed.

[0023] The brake pump 52 controls the opening or closing of the wheel reducer brake on the steel wheel 34 by transmitting pressure through hydraulic oil. The oil pump motor 51 is connected to the vibration motor 32 controlled by the vibration motor controller 31 through an oil circuit to provide a driving medium for its vibration. A vibrator is provided on the steel wheel 34, and the vibration motor 32 controls the vibrator to generate vibration.

The vehicle-mounted controller 4 sends an alarm instruction to the acoustic and visual alarm 82 according to the preset alarm level, and the acoustic and visual alarm 82 sends a corresponding level of light and buzzer sound to alarm according to the received alarm instruction.

[0029] Optionally, the safety warning system 8 also includes an emergency stop switch 83.

A constant tension drum 17 is installed on the cable rack 15. The cable rack 15 includes a cable rack 18 and a first steel wire rope 181; multiple cable racks 18 are arranged at intervals and are tensioned and connected in turn by the first steel wire rope 181.

Among them, the power pulley 16 and the power receiving system 12 arranged at the end and close to the roller are tensioned and pulled by the second steel wire rope 171. The second steel wire rope 171 is coiled in the constant tension drum 17; one end of the cable 19 is connected to the distribution box 14, and the other end is connected to the power receiving system 12 through multiple power pulleys 16 in turn. During the operation of the roller, the cable 19 is connected to the ground through the hanging effect of the power pulley 16, which effectively avoids damage to the cable 19 and improves the safe operation of the roller.

[0035] Step 2: The vehicle controller 4 issues a driving command, so that the driving motor controller 21 controls the driving motor 22 to drive the roller to perform the road rolling work. At the same time, the vehicle controller 4 issues a steering command, so that the control handle 71 controls the steering pump 72 to make the steering cylinder 73 drive the roller to turn, thereby completing the road rolling work of the road section to be constructed.

[0036] Step 3: When the rolling is completed or continues, the vehicle controller 4 issues a cleaning command, the vibration motor controller 31 controls the vibration motor 32 to drive the steel wheel 34 to vibrate, and the vehicle controller 4 controls the cleaning system 6 to start and cooperate to clean the surface of the steel wheel 34.
