Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
The utility model relates to a rope arranging wheel for a tower crane scroll anti-pressing rope, which comprises a main body structure and two support frames 1 and a rope arranging wheel 2, wherein a rotating shaft component 3 is arranged between the support frames 1, and the rotating shaft component 3 is connected with a driving component; the rope discharging wheel 2 is arranged on the rotating shaft component 3, can rotate circumferentially on the rotating shaft component 3, and can move transversely under the driving of the driving component. Because do not follow the steel cable and remove in order to ensure row rope sheave 2, and then play the effect of direction, consequently will require row rope sheave 2 under the condition that can normally carry out normal rotation, also can carry out horizontal removal, and pivot subassembly 3 that this device set up is under drive assembly's drive, can make row rope sheave 2 carry out lateral shifting, and can not receive the influence that the steel cable rocked, and then avoid appearing row rope sheave 2 because follow the steel cable and rock and cause the problem of steel cable cross winding when receiving the line, make the phenomenon of great wearing and tearing can not appear between the steel cable.
A needle bearing 4 is arranged between the rope discharging wheel 2 and the rotating shaft assembly 3. The roller bearing can ensure that the rope guide wheel 2 can be driven to rotate normally when the steel cable is wound and unwound. It should be noted here that although the rope guiding wheel 2 mainly functions as a wire guiding wire, it still bears a small portion of the force of the steel cable, which makes the bearing unable to bear a large radial load and thus the bearing snap easily occurs when the rope guiding wheel 2 moves laterally using a ball bearing. The needle roller bearing 4 can well bear radial load, and then the lateral shifting of the rope arrangement wheel 2 can be well realized.
The rotating shaft assembly 3 comprises a screw rod 5, a fixing rod 6 and a sleeve member 7, the screw rod 5 is rotatably connected with two sides of the support frame 1 and is connected with a driving assembly, and the fixing rod 6 is fixedly arranged on one side of the screw rod 5; the sleeve 7 is provided with a nut 8 matched with the screw rod 5 and a sliding hole 9 matched with the fixed rod 6. The inner ring of the needle bearing 4 is matched with the sleeve 7, and the outer ring of the needle bearing is matched with the inner circular surface of the rope guide 2. This device selects 5 screw 8 transmissions of lead screw as row rope sheave 2 lateral shifting's device, and when drive arrangement drove lead screw 5 and rotates, lead screw 5 can drive external member 7 and rotate, but has the limiting displacement of dead lever 6, consequently can make external member 7 drive row rope sheave 2 and carry out lateral shifting, and then the lateral shifting of guarantee row rope sheave 2 can realize easily.
The driving assembly is a motor 10, and a rotating shaft of the motor 10 is connected with the lead screw 5 and can drive the lead screw 5 to rotate. The drive assembly is connected with a control system, and the control system is also connected with a drive device for driving a tower crane scroll. Because the position that will ensure row rope sheave 2 can effectively follow the steel cable and carry out the winding displacement at first, consequently set up controlling means, make the drive assembly of row rope sheave 2 and the drive arrangement of tower crane spool to synchronous, and then better realization leads to the steel cable.
Therefore, the rope arranging wheel for preventing the rope from being pressed on the winding shaft of the tower crane can enable the rope arranging wheel 2 to limit the position of the steel cable wound and unwound from the winding shaft, and when the steel cable has position deviation when winding and unwinding heavy objects, the rope arranging wheel 2 can not move along with the swinging of the steel cable, so that the phenomenon that the steel cable on the winding shaft is pressed is avoided.
