Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of construction engineering, concretely is a kind of suspension type monorail crane. BACKGROUND

[0002] Monorail crane is a kind of vehicle group with special I-beam suspended in the roadway as track composed of various functional vehicles, monorail crane is mainly composed of traction vehicle, brake vehicle, load-bearing vehicle, etc., and is mainly used for heavy goods transportation.

[0003] The load-bearing vehicle is mainly used for load bearing during goods transportation, and its working principle is that the motor drives the gear set to rotate, the gear set amplifies the torque of the motor and then drives the wire reel with steel cable to rotate, one end of the steel cable is connected with a hook, by winding and unwinding the steel cable, the height of the hook is adjusted, so that the hook is connected with the goods, due to the amplification of the gear set to the torque of the motor, the motor can drive the lifting of the heavy goods, the monorail crane is generally used for long-distance transportation, therefore, the monorail crane needs to be additionally adapted to the power supply, so as to ensure the long-distance work of the monorail crane, in order to ensure the lifting energy of the heavy goods, the power of the motor is transmitted to the pinion, and then the large gear is driven to rotate by the pinion, so as to amplify the torque of the motor, so as to improve the lifting capacity of the monorail crane to the heavy goods, some factories will transport goods in the factory by monorail crane, in order to avoid affecting the mechanical equipment in the factory during transportation, the monorail crane will be installed at a high height, the steel cable will be retracted for safety when the monorail crane is not lifting heavy goods, and the steel cable will be lowered when in use, however, the winding and unwinding of the steel cable by the motor is a deceleration motion of the pinion driving the large gear to rotate, the retraction and lowering of the steel cable needs more turns of the pinion to drive the large gear to rotate, at this time, the rotation of the pinion driving the large gear will increase the energy consumption of the motor, and also reduce the transmission efficiency of the motor to the wire reel.

[0004] The energy-saving suspension type monorail crane disclosed in the publication No. CN119059422A is provided with a variable distance assembly, when the steel cable lifts heavy goods, the wire pressing frame extrudes the pressure regulating assembly to increase the distance between the driving wheel and the driven wheel, at the same time, the push rod frame and the synchronous frame make the auxiliary driving wheel and the driving wheel move synchronously, so that the contact section of the steel belt with the driving wheel and the driven wheel is small, while the contact section of the steel belt with the auxiliary driving wheel and the driving wheel is large, so as to effectively ensure the torque of transmission, facilitate lifting heavy goods, when heavy goods are not lifted, the thrust spring pushes the driving wheel and the driven wheel to contact, so that the distance between the driven wheel and the driving wheel is small, while the distance between the auxiliary driving wheel and the driven wheel is large, at this time, the transmission of the motor to the wire reel is larger, so as to achieve the purpose of energy saving.

[0005] However, the device does not have a limiting device at both ends of the suspension rail body during use, which causes the traction vehicle to collide with the left and right ends of the suspension rail body, thereby causing damage to the traction vehicle and the suspension rail body.

[0006] Therefore, we urgently need to provide a suspension monorail crane. The utility model discloses a suspension monorail crane

[0007] The utility model discloses a suspension monorail crane to solve the problem of damage to the towing vehicle and the monorail body caused by collision between the towing vehicle and the left and right ends of the monorail body during use.

[0009] The anti-collision unit is arranged on the left and right sides of the track, and the cleaning unit is arranged on the left and right sides of the crane.

[0010] The anti-collision unit comprises a side plate, a damping rod, a spring one, a metal plate one, a connecting rod, a metal plate two, a spring two, a power supply and an alarm.

[0011] Preferably, the metal plate one and the metal plate two are connected with the power supply through wires, and the power supply is electrically connected with the alarm.

[0012] Preferably, a rubber pad is arranged on the side of the metal plate one away from the damping rod.
