Detailed Description
The vertical coil electromagnet lifting tool centering equipment comprises an electromagnet lifting beam 1, an electromagnet support 2 and an electromagnet 3.
The electromagnet 3 is arranged below the electromagnet hanging beam 1 through the electromagnet bracket 2.
The center of the electromagnet 3 is provided with a hole and is in a ring shape.
The circumference of 3 center trompils inner circles 4 of electro-magnet evenly is equipped with a plurality of supports 5, all is equipped with an inner circle laser range switch 6 on every support 5 for detect 3 center trompils of electro-magnet tentatively to the heart condition, be four supports 5 in this embodiment, four inner circle laser range switches 6.
A plurality of through holes 7 are formed in the circumference of the electromagnet 3, and a plurality of outer ring laser ranging switches 8 are arranged on the inner side of the electromagnet support 2. And each outer ring laser ranging switch 8 corresponds to the position of the lower through hole 7. In this embodiment, there are four through holes 7 and four outer-ring laser ranging switches 8.
The central hole of the electromagnet 3 is axially provided with a centering guide post 10.
The centering guide post 10 includes a drive portion and a cone 19.
The transmission part comprises a rack slide rail 16, a rack 17 and a guide post bracket 12.
The rack slide rail 16 is vertically fixed on the electromagnet hanging beam 1.
A rack 17 is arranged in the rack slide rail 16.
A guide post bracket 12 is fixed below the rack 17.
The cone 19 is fixed above the guide post bracket 12.
The rack 17 is arranged in the center of the guide post bracket 12 and is embedded in the rack slide rail 16.
The cone 19 is located in the central opening of the electromagnet 3.
The circumferential edge of the conical body 19 is provided with a plurality of grooves 11, and the positions of the grooves 11 correspond to the positions of the bracket 5 and the inner ring laser ranging switch 6. In this embodiment four recesses 11.
The transmission part is connected with a transmission control mechanism.
The transmission control mechanism comprises a gear motor 13, a gear 15 and a guide post positioning and limiting laser ranging switch 18.
The output shaft of the gear motor 13 is transversely arranged, and a gear 15 is arranged.
The gear motor 13 is arranged below the electromagnet hanging beam 1 through a gear motor bracket 14.
The gear 15 is engaged with the rack 17.
A guide post positioning and limiting laser ranging switch 18 is arranged below the electromagnet hanging beam 1.
The working principle is as follows:
the diameter of the opening at the center of the electromagnet 3 is basically consistent with the inner diameter of the steel coil, but is slightly larger than the inner diameter of the steel coil.
Firstly, eight laser sensors are required to be additionally arranged for preliminary positioning of the center.
When the steel coil inner ring emission laser below the four inner ring laser ranging switches 6 is not shielded, the preliminary centering is indicated to be normal, even if the electromagnet 3 always shakes in the centering process, the preliminary centering can be considered to be normal as long as the state that the four inner ring laser ranging switches 6 are not shielded is captured at a certain moment in the shaking process.
Four outer lane laser range finding switches 8 are installed between inner circle 4 and outer lane 9 of electro-magnet 3 for detect the reliable landing of electro-magnet 3, because the magnetic force of electro-magnet 3 receives the clearance to influence very big, it is too big when electro-magnet 3 and coil of strip surface clearance, will seriously lead to electro-magnet 3 seriously impaired to the suction of coil of strip, can lead to the coil of strip emergence of the accident that drops even. Therefore, the four outer ring laser ranging switches 8 are used for detecting the distance between the electromagnet 3 and the surface of the steel coil, and only the four outer ring laser ranging switches 8 are completely detected in place to complete primary positioning.
Because the laser limit is adopted for the center, only preliminary positioning can be carried out, and because the detection precision of the electromagnet 3 and the laser limit is limited, the installation position can not be strictly controlled according to the inner diameter size of the steel coil, so that the lifting appliance can not be centered due to shaking in the running process of a crane, a larger allowance is reserved, and the success rate of centering can be improved. Therefore, the accuracy of centering is reduced, and the centering can occur during hoisting, so that the hoisting fails.
Therefore the utility model discloses set up one set of mechanical guiding device, as shown in fig. 3 and 4, set up a conical body 19 (nylon conical body) at electro-magnet 3 center, centering guide post 10 is when carrying out preliminary location withdrawal to electro-magnet 3 inside, can avoid tentatively leading to the emergence of collision when centering.
After the preliminary centering succeeds, the centering guide post 10 is lowered through a transmission control mechanism and a transmission part (a gear and rack transmission type is adopted in the patent) of the centering guide post 10, and the conical body 19 extends out of the electromagnet 3 to perform secondary accurate centering. The nylon material can avoid the damage of the steel coil. The tip adopts the toper structure can make the direction go on smoothly. Since the upper end of the cone 19 is close to the inner diameter of the steel coil, the centering guide post 10 will finely adjust the electromagnet 3 when it is extended, and finally, the inner ring 4 of the electromagnet 3 will be substantially aligned with the inner ring of the steel coil, thereby completing the operation of precisely centering.
The rack slide rail 16, the rack 17 and the guide column bracket 12 are made of metal (steel), and the conical body 19 is made of nylon. The conical body 19 is of a structure with a small lower part and a large upper part. The transmission part adopts a rack transmission structure, and the gear motor 13 drives the gear rack structure to lower and retract the conical body 19. When the hoist carries out preliminary centering, because the hoist rocks, if conical body 19 exposes, can lead to the collision to take place unavoidably, so inside 3 electro-magnets are withdrawn to conical body 19 when preliminary centering, accomplish the back at preliminary centering, transfer conical body 19 gradually, make electro-magnet 3 take place the displacement of minim through conical body 19's direction to make the heart more accurate, guarantee the success rate of handling.
The rack slide 16 and the rack 15 need to be in a tight sliding fit. The gear motor 13 is arranged below the electromagnet hanging beam 1 through a gear motor bracket 14 and drives a gear 15 to rotate. The gear 15 is matched with the rack 17 to drive the rack 17 to move up and down, so that the centering guide column 10 is moved up and down, and the lowering and retracting actions of the centering guide column 10 are realized. In order to ensure the smooth action of the centering guide column 10, the electromagnet 3 needs to be fixed below the electromagnet hanging beam 1 through the electromagnet bracket 2, and the relative position of the electromagnet 3 and the electromagnet hanging beam 1 is ensured to be fixed, so that the rack 17 can smoothly control the telescopic motion of the centering guide column 10. In order to ensure the accuracy of the action position of the centering guide post 10, a guide post positioning limit laser ranging switch 18 is arranged below the electromagnet hanging beam 1 and above the upper surface of the corresponding guide post bracket 12, adopts laser ranging limit, and is provided with two groups of output nodes which can be used for positioning the retracted position of the centering guide post 10 and the extended position of the centering guide post 10. The inner ring laser ranging switch 6 and the outer ring laser ranging switch 8 are both made of SICK products, and the type of the SICK products is V18. The gear motor 13 adopts a common alternating current motor, the working power supply is 380VAC,50HZ and the power is 0.5 kW.
