Guide wheel of mobile cantilever crane
During the vertical operation of mobile cantilever crane,the guide wheel can also be used to guide the operation,but when using the guide wheel,the structure and equipment of the frame must be paid attention to during the welding operation.The main purpose of this equipment is to identify the sum of the stable torque and various reaction forces of the wheel relative to the steering linkage.
Mobile cantilever crane does not use wheels in motion,but also uses guide wheels.But the wheel is one of the most important parts in the crane working device,and the guide wheel is the most important auxiliary part in the crane working device.Help is helpful.When the lifting trolley adapts to the work and steering on the curved track,the horizontal guide wheel of the mobile cantilever crane working on the curve is used as the open gear of the reducer with low speed output.For the lifting trolley with low building height,in addition to adding counterweight equipment,it is planned to start the lifting trolley without counterweight.The guide wheel is equipped with a reverse supporting wheel on the frame of the working trolley to support the appearance under the track and become a counterweight trolley.
The guide wheel is composed of runner and left and right guard plates.The lower ends of the left and right guard plates are connected with fastening bolts.The runner is fixed between the left and right guard plates through shaft equipment.The shaft is fixed with the left and right guard plates,and the runner is connected with the shaft in relative rotation.The utility model is characterized in that the upper part is provided with a shaft hole.The left and right anti stripping reinforcing plates and pin shafts are respectively the corresponding fixed joints on the inside of the left and right anti stripping reinforcing plates,and the pin shafts pass through the shaft holes of the left and right anti stripping reinforcing plates;The equipment is movably connected with the anti stripping reinforcing plate.
This is the guiding work of the guide wheel.Under a certain working environment,the reaction force of the wheel is the main purpose of the guide wheel.In terms of materials,the horizontal guide wheel is mainly made of 45 steel.The utility model has the advantages of good wear resistance and long service life.This guidance reduces the accidents of broken rope sports car and guide wheel decoupling sports car,promotes safety production,saves the input of guide wheel,and extends the service life of wire rope.
