Description

Technical Field

[0001] The invention relates to the technical field of crane driving, and in particular to a crane drum wire rope miswinding detection device and method. Background Art

[0002] Crane is the common name for cranes such as cranes, overhead cranes and overhead cranes. Cranes are basically the same as what we call cranes. There are basically two types of crane drive modes: one is centralized drive, that is, an electric motor drives a long transmission shaft to drive the active wheels on both sides; the other is separate drive, that is, the active wheels on both sides are driven by a motor respectively. Medium and small bridge cranes mostly use a "three-in-one" drive method that combines brakes, reducers and motors into one. For the convenience of installation and adjustment, ordinary bridge cranes with large lifting capacity often use universal couplings in the drive device.

[0003] The patent document with publication number CN110759267B discloses an unmanned vehicle with a wire rope winding detection function, including a drum, a left wire rope, a right wire rope, and a support frame, the drum is installed on the support frame, one end of the left wire rope and the right wire rope are wound on the drum, and the other end is hung down and connected to a lifting mechanism; it also includes a controller and a detection device, the detection device includes an upper bracket, a detection cable, a counterweight, and a first proximity switch, the upper bracket is fixed on the support frame, the first proximity switch is fixed on the upper bracket, the front end of the detection cable is fixed to the support frame, the middle part spans the support frame and is inserted between the left wire rope and the right wire rope, the tail part is movably attached to the upper bracket, the end passes around the top of the upper bracket and then hangs down and is connected to the counterweight, the counterweight is arranged in alignment with the first proximity switch, and the first proximity switch is associated with the controller signal.

[0004] In the above application documents, after the left and right steel ropes are entangled, since the detection cable is passed between the two left steel ropes and the two right steel ropes, it will be entangled with the left and right steel ropes, thereby driving the counterweight to slide upward in the sleeve, and causing the slide bar to slide upward in the track groove to the first proximity switch and the second proximity switch in sequence, so that the entanglement is detected by the detection device. The distance between the detection cable and the entanglement of the left and right steel ropes is uncontrollable. When the suspended object moves downward, the entanglement of the left and right steel ropes may be far away from the detection cable and the detection device cannot be triggered, which is not conducive to safety and needs to be improved.

The side of the pressure chamber 152 is penetrated and fixedly connected with an oil suction pipe 1510. The end of the oil suction pipe 1510 away from the pressure chamber 152 is penetrated and fixedly connected to the lubricating oil tank 151.

Both the inside of the oil suction pipe 1510 and the inside of the oil delivery pipe 156 are provided with a one-way valve. The one-way valve in the oil suction pipe 1510 is a one-way valve toward the inside of the pressure chamber 152. The one-way valve in the oil delivery pipe 156 is one-way conductive in the direction of the oil injection pipe 157. When negative pressure is formed in the pressure chamber 152, the lubricating oil in the lubricating oil tank 151 is sucked into the pressure chamber 152 through the oil suction pipe 1510. When the lubricating oil in the pressure chamber 152 is squeezed, the lubricating oil in the pressure chamber 152 is discharged to the oil injection pipe 157 through the oil delivery pipe 156. An atomizing nozzle 158 is provided at the end of the oil injection pipe 157 away from the pressure chamber 152. A one-way moving component 159 is provided at the bottom of the sliding rod 155. The one-way moving component 159 includes a gear rod 1591 and a rotating ring 1592. The gear rod 1591 is The top is fixedly connected to the bottom of the sliding rod 155, the rotating ring 1592 is fixedly connected to the surface of the rotating rod 142, the surface of the rotating ring 1592 is provided with a groove 1593, the interior of the groove 1593 is provided with a telescopic spring 1594, the interior of the groove 1593 is slidably connected with an arc block 1595 through the telescopic spring 1594, when the rotating ring 1592 rotates counterclockwise following the rotating rod 142, it drives the gear block rod 1591 to move downward through the straight surface of the arc block 1595, the uniform mechanism 16 includes an air pressure chamber 161, a fixed ring 164 and an extrusion block 165, the air pressure chamber 161 is fixedly connected to the support At the top of the frame 8, an elastic airbag 162 is provided at one end of the air pressure chamber 161, and a piston rod 163 is slidably connected to the internal piston at the other end of the air pressure chamber 161, and a fixing ring 164 is fixedly connected to the surface of the oil injection pipe 157, and the end of the piston rod 163 away from the air pressure chamber 161 is fixedly connected to the fixing ring 164, and the extrusion block 165 is fixedly connected to the surface of the shaft 9. The elastic airbag 162 is in an expanded state in the initial state, and the end of the elastic airbag 162 away from the air pressure chamber 161 is close to the surface of the shaft 9. When the shaft 9 rotates, the array of extrusion blocks 165 will be mobilized to repeatedly squeeze the elastic airbag 162.

[0036] When in use, the moving motor 4 is turned on to drive the threaded rod 5 to rotate. The rotation of the threaded rod 5 will drive the slider 6 to move along the slide groove 3 through the cooperation between the threads. The movement of the slider 6 drives the moving seat 7 to move so that the hook 12 moves to the top of the object. Then the lifting motor 17 is turned on to drive the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the reel 10 to unwind the wire rope 11 thereon, so that the hook 12 can be steadily lowered through the four groups of wire ropes 11, and the four groups of limiting wheels 13 can guide the four groups of wire ropes 11 to prevent the moving trajectory from deviating. At the same time, the winding motor 143 can be turned on to drive the rotating rod 142 and the unwinding roller 144 to rotate to unwind the rope 145, so that the rope 145 drives the lifting block 146 to rise and fall synchronously with the hook 12, and the reel When the hook 12 and the suspended object are raised by rotating in the direction of 10, the steel wire rope 11 may shake and cause the four groups of steel wire ropes 11 to be entangled. When the four groups of steel wire ropes 11 are entangled, they will squeeze the two groups of squeezing plates 149 to make them move toward the inner direction of the lifting block 146. When the two groups of squeezing plates 149 move toward the inner direction of the lifting block 146, they will contact the sensor 1410. The sensor 1410 will transmit the signal to the signal transmitter 147, and the signal transmitter 147 will transmit the signal to the control end 2, so as to remind the operator to stop the rise of the hook 12 and drive the suspended object to slowly descend, and operate again after the suspended object is stable, which effectively improves the safety. In the process of driving the hook 12 and the suspended object to rise, the retracting is turned on. The winding motor 143 drives the rotating rod 142 and the unwinding roller 144 to rotate counterclockwise to reel in the lifting rope 145, so that when the lifting block 146 rises synchronously, the counterclockwise rotation of the rotating rod 142 will drive the rotating ring 1592 to rotate counterclockwise, and when the rotating ring 1592 rotates counterclockwise, it will drive the gear block rod 1591 to move downward through the straight surface of the arc block 1595, and the downward movement of the gear block rod 1591 will drive the sliding rod 155 and the piston plate 154 to move downward, the reset spring 153 is stretched, and the downward movement of the piston plate 154 will form a negative pressure in the pressure chamber 152. When the negative pressure is formed in the pressure chamber 152, the lubricating oil in the lubricating oil tank 151 will be sucked into the pressure chamber 152 through the oil suction pipe 1510, and when the rotating ring 1592 rotates to the point where there is no arc block When the piston plate 154 and the sliding rod 155 are halfway to the left, the return spring 153 rebounds and drives the piston plate 154, the sliding rod 155 and the tooth block rod 1591 to move upward and return to the original position. At this time, the piston plate 154 squeezes the lubricating oil in the pressure chamber 152, causing the lubricating oil in the pressure chamber 152 to be discharged to the oil injection pipe 157 through the oil delivery pipe 156, and finally is atomized by the atomizing nozzle 158 and sprayed onto the wire rope 11 on the drum 10, forming a cycle. By spraying the lubricating oil on the wire rope 11, the rust and wear of the wire rope 11 are prevented from affecting the service life. When the rotating rod 142 rotates clockwise, the arc surface of the arc block 1595 contacts the tooth block on the tooth block rod 1591. At this time, the arc surface of the arc block 1595 is squeezed and shrinks into the groove 1593, which will not drive the tooth block rod 1591 to move.Then the telescopic spring 1594 drives the arc block 1595 to pop out and restore. When the lifting motor 17 drives the rotating shaft 9 to rotate, the array extrusion block 165 will repeatedly squeeze the elastic airbag 162 as it rotates with the rotating shaft 9. The elastic airbag 162 is squeezed and the air pressure inside it will enter the air pressure chamber 161 to drive the piston rod 163 to move out of the air pressure chamber 161. The movement of the piston rod 163 out of the air pressure chamber 161 will drive the oil injection pipe 157 to move through the fixed ring 164. When the elastic airbag 162 rebounds and the air pressure returns from the air pressure chamber 161 to the elastic airbag 162, the piston rod 163 drives the fixed ring 164 and the oil injection pipe 157 to move in the opposite direction to restore. By driving the oil injection pipe 157 and the atomizing nozzle 158 to move back and forth, the lubricating oil can be sprayed onto the steel wire rope 11 on the drum 10 more evenly, thereby improving the spraying effect.

When the four groups of steel wire ropes 11 are entangled, a signal will be sent to the output end through the cooperation of the extrusion plate 149, the compression spring 148, the sensor 1410 and other components to remind the operator;

[0040] S2, turn on the winding motor 143 to drive the rotating rod 142 and the unwinding roller 144 to rotate counterclockwise to wind up the suspension rope 145, so that when the lifting block 146 rises synchronously, the lubricating oil will be sprayed onto the steel wire rope 11 on the drum 10 through the atomizing nozzle 158 coordinated with the pressure chamber 152, the piston plate 154, the one-way moving component 159, etc., to spray the steel wire rope 11;

[0041] S3.
