Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-6 This utility model provides a technical solution for an intelligent inductive wire rope guide for lifting equipment. The fixed drive mechanism 1 includes a fixed frame 1.1, a sliding seat 1.4 that moves laterally along the front of the fixed frame 1.1, and a screw drive mechanism for driving the sliding seat 1.4 to reciprocate laterally. A screw 1.2 is rotatably mounted between the middle of the two sides of the fixed frame 1.1. A servo motor 1.3 with a power output shaft fixedly connected to the screw 1.2 is fixed to the outer wall of one side of the fixed frame 1.1. Guide rods 1.6 are respectively provided on the upper and lower sides of the fixed frame 1.1, which slide and fit with the top and bottom ends of the rear of the sliding seat 1.4. A drive nut 1.5 that is threadedly fitted to the rear of the sliding seat 1.4 is fixedly fitted. That is, the servo motor 1.3 drives the screw 1.2 to rotate, and the rotating screw 1.2 drives the sliding seat 1.4 to slide laterally under the guidance of the guide rods 1.6 through the drive nut 1.5.

[0015] The vertical guide rope seat 2 includes a back plate 2.1 fixed to the front wall of the sliding seat 1.4, a wheel frame 2.2 fixed to the top and bottom of the back plate 2.1, a transverse guide wheel 2.3 rotatably mounted on the extended end of the wheel frame 2.2, and a pair of fixing plates 2.4 fixed to the upper and lower sides of the middle of the front wall of the back plate 2.1. The fixing plate 2.4 has a through hole 2.4.1 in the middle. The top end of the wheel frame 2.2 extends forward and upward, and the bottom end of the wheel frame 2.2 extends forward and downward.

[0016] The transverse guide rope component 3 includes a wheel seat 3.1 that is slidably engaged with the front wall of the back plate 2.1 and located inside the fixed plate 2.4, a guide roller 3.2 that is rotatably sleeved on the rear end of the central shaft and connected to the wheel seat 3.1, and a screw 3.3 that is vertically fixed to the outer wall of the wheel seat 3.1 and sleeved with the through hole 2.4.1.

[0017] Pressure sensors 4 are located inside the fixed plate 2.4 and are mounted on the screw 3.3.

[0018] The locking nut 5 is threaded onto the outer end of the screw 3.3; a washer is fitted onto the screw 3.3 between the locking nut 5 and the fixing plate 2.4. By installing different numbers of washeres, the distance between the two pairs of transverse guide rope pieces 3 can be adjusted to guide wire ropes of different diameters.

[0019] Control module 6 controls the start / stop and direction of the lead screw drive mechanism based on the monitoring signals from pressure sensor 4. The output of control module 6 is connected to motor control unit 6.1, which controls the direction and start / stop of servo motor 1.3. Using a PLC as control module 6, four pressure sensors 6 monitor the pressure of the steel wire rope received by the corresponding guide roller 3.2 and output analog signals. Control module 6 has analog input and analog output, and motor control unit 6.1 is a servo driver. The forward / reverse rotation and start / stop of servo motor 1.3 are controlled based on the pressure values ​​monitored by the four pressure sensors 6.

[0020] For example: P1 is set to the measured value of the upper left pressure sensor 6; P2 is the measured value of the upper right pressure sensor 6; P3 is the measured value of the lower left pressure sensor 6; P4 is the measured value of the lower right pressure sensor 6; P max It is the maximum value among P1, P2, P3, and P4.

[0021] The control logic is as follows: When P max When the value is >A (A is a positive threshold), it indicates that there is excessive stress on the wire rope between the wire rope drum and the hook, which needs to be alleviated by adjusting the movement of the sliding seat 1.4.

[0022] Where, if P max When it is either P1 or P3, the servo motor 1.3 rotates forward to drive the sliding seat 1.4 to move to the left through the lead screw 1.2, that is, to move the transverse guide rope 3 to the left.

[0023] If P max When it is either P2 or P4, the servo motor 1.3 reverses to drive the sliding seat 1.4 to move to the right via the lead screw 1.2, that is, to move the transverse guide rope 3 to the right.

[0024] When P max If A ≤ A (A is a positive threshold), servo motor 1.3 stops.

[0025] To prevent the wheel seat 3.1 from becoming misaligned, the front wall of the back plate 2.1 is provided with a guide rail 2.5 extending laterally between the two fixed plates 2.4, and the rear wall of the wheel seat 3.1 is provided with a slot 3.1.1 that slides and matches the guide rail 2.5.
