The capstan variable frequency motor 13 is fixed on the base frame 11 through a motor bracket 131. A transfer case 14 is arranged on the other side of the base frame 11.

The threaded sleeve 145 has internal threads, and a meshing gear ring is provided at the outer inner end of the threaded sleeve 145, and a meshing tooth surface is provided at the outer outer end of the threaded sleeve 145. The meshing gear ring at the inner end of the threaded sleeve 145 can mesh with the inner gear rings of the slow clutch gear 143 and the fast clutch gear 144. A linkage rod 146 parallel to the rotating main shaft 141 is rotatably provided on one side of the rotating main shaft 141 in the transfer case 14. The linkage rod 146 is fixedly connected with a sector gear 147 at the positions corresponding to the two threaded sleeves 145, and each sector gear 147 meshes with the meshing tooth surface on the threaded sleeve 145 at the corresponding position.

[0047] The outer side of the transfer case 14 is connected to a shift drive mechanism 16 for driving the linkage rod 146 to rotate. The shift drive mechanism 16 drives the linkage rod 146 to rotate, thereby driving the two sector gears 147 fixed on the linkage rod 146 to rotate, and the sector gears 147 are engaged with the meshing tooth surfaces outside the two threaded sleeves 145 to drive the threaded sleeves 145 to move axially in the same direction synchronously, thereby achieving the meshing gear ring at the inner end of the threaded sleeve 145 to mesh with one of the slow gear clutch gear 143 and the fast gear clutch gear 144, and the other is separated to achieve clutch. As one embodiment, the shift drive mechanism 16 includes an electric push rod 161 arranged on the transfer case 14, and the electric push rod 161 is connected to a push connecting rod 162, and the push connecting rod 162 is connected to the linkage rod 146.

[0049] The double-drum capstan mechanism 12 includes a gear box 121 and two drums 122. Two support shafts 123 are arranged perpendicular to the rotating main shaft 141 in the gear box 121. The ends of the support shafts 123 away from the capstan variable frequency motor 13 extend out of the gear box 121 and are connected to the drums 122. The two support shafts 123 are meshed with bevel gears fixed at the ends of the elastic coupling 153 through a gear set. The two drums 122 on the double-drum capstan mechanism 12 on one side of the capstan variable frequency motor 13 are used to connect one of the steel wire ropes for lifting or amplitude change, and the two drums 122 on the double-drum capstan mechanism 12 on the other side of the capstan variable frequency motor 13 are used to connect the other steel wire rope for lifting or amplitude change.

[0050] Under the drive of the capstan frequency conversion motor 13, by controlling the electromagnetic clutch 152, the synchronous action of the four drums 122 connecting the two steel wire ropes for lifting or the two steel wire ropes for amplitude change can be achieved.

[0051] The electric tail rope collecting devices 2 are respectively arranged corresponding to the two double-drum capstan mechanisms 12. Each electric tail rope collecting device 2 is arranged at the rear of the two double-drum capstan mechanisms 12.

[0052] See also Figures 8 to 10 The electric tail rope collecting device 2 includes a frame 21, a wire drum 22 and a tail rope variable frequency motor 231 are arranged at the rear end of the frame 21, the wire drum 22 is rotatably mounted on the frame 21 through a driving shaft 232, and the tail rope variable frequency motor 231 is connected to the driving shaft 232 to drive the wire drum 22 to rotate. A small sprocket 233 is fixedly sleeved at the end of the driving shaft 232 near the tail rope variable frequency motor 231.

[0053] The front end of the frame 21 is provided with a cable arrangement main shaft 241 and a cable arrangement secondary shaft 242 parallel to the drive shaft 232, and the cable arrangement main shaft 241 is located between the drive shaft 232 and the cable arrangement secondary shaft 242.

The reciprocating sleeve 243 is connected to a wire arrangement wheel, which specifically includes a wire arrangement base 244 fixedly connected to the middle of the reciprocating sleeve 243, and a rotatable horizontal roller 245 parallel to the wire arrangement main shaft 241 is arranged at one end of the wire arrangement base 244 close to the driving shaft 232, and two rotatable vertical rollers 246 are arranged at intervals at one end of the wire arrangement base 244 close to the wire arrangement secondary shaft 242.

[0054] Driven by the tail rope frequency conversion motor 231, the drive shaft 232 and the cable arrangement main shaft 241 rotate synchronously. At the same time, the reciprocating sleeve 243 reciprocates along the axial direction of the cable arrangement main shaft 241, so that the tail rope is arranged on the cable drum 22 in an orderly and tight manner.

[0055] A tension detector for detecting the tension of the tail rope is arranged between the line drum 22 and the cable arrangement main shaft 241. The tail rope passes through the tension detector during the collection process. The tension detector monitors the tension of the tail rope in real time and feeds back the data to the control system. The control system automatically adjusts the rotation speed of the tail rope frequency conversion motor 231 according to the real-time tension information fed back by the tension detector. The detection range of the tension detector is 45kg-55kg.

[0056] The operating method of the above-mentioned four-drum synchronous motorized capstan rope collecting device specifically includes the following steps:

[0057] Step 1: Check the various components of the synchronous motorized capstan equipment 1, including the base frame 11, the motor bracket 131, the capstan frequency conversion motor 13, the cross coupling 151, the transfer case 14, the clutch cone 142, the slow gear clutch gear 143, the fast gear clutch gear 144, the shift drive mechanism 16, the sector gear 147, the threaded sleeve 145, the electromagnetic clutch 152, the elastic coupling 153 and the gear box 121, etc., to ensure that all the components are intact and the fasteners are not loose;

[0058] Step 2: Check the frame 21, the wire drum 22, the tail rope variable frequency motor 231, the tension detector and the control system of the electric tail rope collecting device 2 to ensure that each component functions normally and is firmly connected;

[0059] Step 3: Turn on the power supply, start the capstan frequency conversion motor 13 for preheating, and ensure that the capstan frequency conversion motor 13 runs smoothly without abnormal sounds; check the initial states of the electric push rod 161, the electromagnetic clutch 152 and other components to ensure that they are in the correct working position;

[0060] Step 4: Start the capstan variable frequency motor 13, the capstan variable frequency motor 13 starts to run and generates power, and the power is transmitted to the transfer case 14 through the cross coupling 151;

[0061] Step 5: Select the slow gear or fast gear mode according to the operation requirements. When the slow gear or fast gear is selected, the electric push rod 161 drives the linkage rod 146 by pushing the connecting rod 162, and the corresponding threaded sleeve 145 is meshed with the corresponding slow gear clutch gear 143 or fast gear clutch gear 144 through the sector gear 147, thereby realizing power transmission;

[0062] Step 6: Power is transmitted from the transfer case 14 to the four drums 122 through the electromagnetic clutch 152 and the elastic coupling 153. The electromagnetic clutch 152 performs a clutch operation according to the control signal. The four drums 122 start to operate synchronously under the driving of the power to perform the capstan grinding operation.

[0063] Step 7: During the capstan operation, the operator needs to pay close attention to the operating status of the equipment and the capstan effect, and adjust the speed and direction of the motor in real time to meet different capstan requirements. If there is an abnormal situation or shutdown is required, the operator should immediately press the emergency stop button to ensure the safety of the equipment and personnel;

[0064] Step 8: When the capstan operation starts, two electric tail rope collecting devices 2 are started at the same time, and the tail rope variable frequency motor 231 drives the wire drum 22 to start rotating, ready to collect the tail rope;

[0065] Step 9: The large sprocket 234 cooperates with the small sprocket 233 to rotate the cable arrangement main shaft 241 through the transmission of the chain 235; the tail rope is wound on the cable drum 22 through the cable arrangement channel on the cable arrangement main shaft 241, and the orderly arrangement of the tail rope is achieved through the reciprocating motion of the cable arrangement wheel;

[0066] Step 10: When the tail rope passes through the tension detector, the tension detector monitors the tension of the tail rope in real time and feeds the data back to the control system. The control system automatically adjusts the speed of the tail rope variable frequency motor 231 according to the data fed back by the tension detector, so that the collection speed of the tail rope matches the working speed of the capstan.

[0067] Step 11: The tail rope after the arrangement is finally tightly and orderly wound on the wire drum 22, and the wire drum 22 is connected to the tail rope frequency conversion motor 231 through the driving shaft 232. The rotation of the tail rope frequency conversion motor 231 drives the wire drum 22 to rotate, thereby realizing the automatic collection of the tail rope;

[0068] Step 13: When the synchronous motorized capstan equipment 1 completes its work and stops running, the electric tail rope collecting device 2 also stops working.
