2. When no floater on water exists, the cutting device is lifted to the position above the water surface by the winch to be refueled and maintained, and the service life of the equipment is effectively prolonged.
3. When high stop device prevented that operating personnel from operating cutting device oscilaltion, misoperation made the motor go into water, damaged the motor.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
Through inventor's experiment and observation, the floater on water is often blockked by the pier stud 92 of construction landing stage, and the floater can be the great piece gathering in the upper reaches of landing stage 9, and the gathering of the great piece floater can block up the river course to influence the safety of navigating in river course.
The floating object is usually made up of wood, bamboo, reed and aquatic weed materials through interweaving and winding. The large gathering of floater is not only can block up the river course in the upper reaches of construction landing stage, also can increase the rivers impact pressure of pier stud 92 side direction simultaneously, and then leads to the incident that construction landing stage unstability topples. In this technical scheme, use cutting device 3 to cut the floater on the surface of water, avoid floater to interweave a large amount of gathers after the winding.
Specifically, as shown in fig. 1 and 2, a support plate 4 is provided on the pier stud 92, and a lifting drive device 1, such as a winch, is mounted on the support plate 4. A guide bar 2 extending in the vertical direction is installed on the side surface of the pier stud 92, and a slide 21 is provided in the guide bar 2. The cutting device 3 is lifted along the slideway 21 in the vertical direction, and the lifting power is from the winch.
The basic component of the cutting device 3 is a connecting frame 34, and the connecting frame 34 can be provided with a slide block or a pulley matched with the slide rail 21. The connecting frame 34 is provided with two driving wheels 35 arranged at different height positions, and the driving chain 32 is connected with the two driving wheels 35 in a closed loop mode. The cutting drive 31 may be a motor mounted on the connecting frame 34 near the upper side, i.e. away from the water surface, and the drive shaft of the motor is connected to the upper drive wheel 35, and the entire endless drive chain 32 is driven to rotate by the operation of the motor. The plurality of blades 33 are uniformly arranged on the transmission chain 32 at intervals, and the blades 33 move rapidly along with the rotation of the transmission chain 32, so that the effect of rapidly cutting the floating objects on the water surface is achieved.
When floaters on the upper stream of the construction trestle are gathered, the winch puts the cutting device 3 down to a certain depth below the water surface, the power is switched on to start the motor, the transmission chain 32 is driven by the motor to rotate at a high speed, the plurality of blades 33 cut off the floaters on the water surface, and the floaters can flow away along with the water after being cut off. When no floater on water exists, the cutting device 3 is lifted to the position above the water surface by the winch to be refueled and maintained, and the service life of the equipment is effectively prolonged.
In the present case, there is also a height limiting device for limiting the lowering height of the cutting device 3. The height limiting device can be implemented in various ways, such as sensor limiting, a photoelectric switch is arranged at a certain height position of the pier 92, and when the photoelectric switch detects that the cutting device 3 passes through the height position, the winch stops descending the cutting device 3. Or a physical limit, for example, a limit stop is provided at a certain position of the slideway 21, when the cutting device 3 descends to a certain height, the slide block on the connecting frame 34 contacts with the limit stop to stop the cutting device 3 from further descending.
The height limiting device has the effect that when an operator operates the cutting device 3 to lift up and down, misoperation causes the motor to enter water and damage the motor. In practice, the cutting device 3 is often moved down into the position 30 cm-80 cm below the water surface and locked.
