Description

Technical Field

[0001] The invention relates to the technical field of large cable suspension devices, in particular to a cable head hook device for sheath extrusion of an extruder. Background Art

[0002] In the process of extrusion of the sheath of the extruder, due to the lack of a well-designed cable head hook device, only a thin shaft is used to pass through the bottom of the cable head, and the two ends of the thin shaft are lifted by hand, which can easily cause operator errors, causing the cable head to fall into the cooling water tank during traction, causing water to enter the cable. If water enters the head, the cable with water in the head can only be cut off, affecting the number of meters of cable delivery; if water enters the middle of the cable, it is difficult to handle and dry it, even if a blow dryer is used, it is difficult to blow it dry completely. Once the cable is shipped, in the long-term operation process, the water in the cable becomes a potential hidden danger that affects the safe operation of the cable, and may eventually cause the cable to break down or return, with very serious consequences. The above situation will occur more frequently when encountering the production of large-section cables, and the existing technology cannot solve the above technical problems.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-4As shown, a cable head hook device for sheath extrusion of an extruder includes guide rollers 3 arranged on both sides of a track A. The track A is an I-shaped steel plate track. The track A is welded to a bracket 29. The bracket 29 is fixed to the ground through an expansion tube and bolts. Ensure that the track A is located above the cooling water tank 26. Baffles are provided at both ends of the length direction of the I-shaped steel plate track to prevent the guide roller 3 from sliding out. A flange baffle 22 with a thickness of 4-5 mm is provided on one side of the guide roller 3. The baffle 22 is close to the side end face of the track A. The outer diameter of the flange baffle 22 is 5-6 mm larger than the outer diameter of the guide roller 3 to reduce the shaking of the two guide rollers 3 rolling on both sides of the I-shaped steel track.

[0029] Each guide roller 3 is provided with bearings 2 on both sides of the inside, and a guide roller shaft 6 is mounted on the inner ring of the bearing 2.

The thread diameters of both ends of the stud 9 where they pass through the first cover plate 13 and the second cover plate 21 are 1-2 mm smaller than the diameters of other positions of the stud 9. The ends of the stud 9 are positioned by a second nut 8 and a second gasket 7.

[0031] A hook shaft 12 is installed between the lower part of the first cover plate 13 and the lower part of the second cover plate 21, and the two ends of the hook shaft 12 are connected to the first cover plate 13 and the second cover plate 21. An adjusting sleeve 14 is installed in the middle of the hook shaft 12. The upper end of the adjusting sleeve 14 is milled with a flat square. The inner diameter of the hole on the flat square is 2-3 mm larger than the outer diameter of the middle end of the double-headed stud 12. It is used to be installed on the hook shaft 12. The inner side of the adjusting sleeve 14 is provided with an internal thread, and an adjusting rod 16 is installed in the internal thread. The adjusting rod 16 is also equipped with an adjusting nut 15. The lower end of the adjusting rod 16 is milled with a flat square, and a wire rope hole is opened on the flat square. A wire rope 18 is installed in the wire rope hole. A hook 20 is installed at the lower end of the wire rope 18. The upper end of the wire rope 18 passes through the lower end of the adjusting rod 16 and is fixed by the first 8-shaped aluminum sleeve 17.

Install the hole with a flat square milled on one end of the adjustment sleeve 14 into the middle of the hook shaft 12.

[0034] Lift the above components again and place the two guide rollers 3 at one end of the first cover plate 13 into one side of the I-beam of the track A, and then place the two guide rollers 3 at one end of the second cover plate 21 into the other side of the track device A. At the same time, the two studs 9 and the other end of the hook shaft 12 must also pass through the second cover plate 21, and the two are fixedly connected by their respective second gaskets 7, second nuts 8 and third gaskets 10, third nuts 11.

[0035] After the adjusting sleeve 14 is connected to the adjusting rod 16, the size that can be adjusted up and down is cut. The steel wire rope 18 of appropriate size is connected to the adjusting rod 16 at one end through the pressed first 8-shaped aluminum sleeve 17, and the other end is connected to the hook 20 through the pressed second 8-shaped aluminum sleeve 19; lift the adjusting rod 16 and screw one end of the screw into the inner thread on the adjusting sleeve 14; screw the screw of the adjusting rod 16 into the appropriate size according to the cross-sectional size of the cable core 23 to be sheathed and extruded, and after the hook head of the hook 20 is perpendicular to the center line of the cable core 23 to be sheathed and extruded, tighten the adjusting nut 15.

[0036] After all the heating systems of the entire extruder are heated to the process temperature, during the production process of the sheath extrusion of the extruder, the hook head of the hook 20 should be inserted into the connection between the cable core to be extruded and the traction rope, and higher than the water surface of the cooling water tank 26. The hook head of the hook 20 should be held by hand. After the cable head passes through the cooling water tank 26 and is lowered from the hook 20, the machine can be accelerated and started normally.
