Description

Technical Field

[0001] This utility model relates to the technical field of cable laying devices, specifically to a limiting device for the rotating shaft of a cable laying frame. Background Technology

[0002] When arranging and installing active pay-off frames for wire reels of Φ630 and below on a cantilever single-twisting machine, sometimes two active pay-off frames are installed simultaneously on a single rotating shaft to achieve a smoother pay-off angle between the wire distributor and the active pay-off frame outlet, and to save installation space. The rotating shaft is connected to a base bearing, allowing it to rotate on the base, facilitating the installation and removal of the wire reels on the two active pay-off frames simultaneously mounted on the shaft. A rotatable protective net is installed around the base, and the installation and removal of the wire reels on the active pay-off frames are all performed outside the protective net. For safety reasons, the protective net must be closed after the wire reels on the active pay-off frames are installed in place before the main machine can be started.

[0003] When the main unit is turned on for production, how to limit the appropriate angle between the rotating shaft and the base to ensure that the two active wire feeding frames installed on the rotating shaft can operate reliably and smoothly has always been a problem that has troubled relevant technicians in this field.

A limiting seat 1 is welded to the front side of the rotating shaft 10 on the base 11. The limiting seat 1 has a through hole c1.1, and a sliding rod 9 is inserted into the through hole c1.1 with clearance fitting, so that the sliding rod 9 can be lifted or inserted from the through hole 1.1 of the limiting seat 1. A fixing plate 3 is welded to the front side of the rotating shaft 10. A sliding sleeve 5 is sleeved on the sliding rod 9, and a fixing plate 7 is welded to the sliding sleeve 5. The fixing plate 7 and the fixing plate 3 are fixedly connected by pads 12 and hexagon socket head cap screws 4. The fixing plate 3, the fixing plate 7, and the two pads 12 have the same height.

[0016] The sliding sleeve 5 is provided with a stepped hole, which consists of a large-diameter hole 5.2 at the lower end and a small-diameter hole 5.3 at the upper end. The sliding rod 9 consists of a large-diameter section 9.2 at the lower end and a small-diameter section 9.1 at the upper end. The upper end of the large-diameter section 9.2 is inserted into the large-diameter hole 5.2 with a clearance fit, and the small-diameter section 9.1 is inserted into the small-diameter hole 5.3 with a clearance fit. A cylindrical helical compression spring 8 is sleeved on the small-diameter section 9.1 inside the large-diameter hole 5.2.

[0017] The sliding sleeve 5 has a spiral curved sliding hole 5.1 machined on it. The rotating handle 2 is inserted into the spiral curved sliding hole 5.1 and threaded onto the large-diameter section 9.2 of the sliding rod 9. The outer end surface of the rotating handle 2 is knurled. This design ensures reliable sliding of the sliding rod 9 inside the sliding sleeve 5.

[0018] The fixing plate 2 7 has through holes a7.1 machined at its four corners. The left and right sides of the rear side of the fixing plate 2 7 are welded with pads 12. The pads 12 have through holes b12.1 corresponding to the positions of the through holes a7.1. The diameters of the through holes a7.1 and b12.1 are the same and they are clearance-fitted with the external threads of the hexagon socket head cap screws 4. The fixing plate 1 3 has screw holes 3.1 machined at its four corners. The hexagon socket head cap screws 4 pass through the through holes a7.1 and b12.1 and are threaded into the screw holes 3.1.

[0019] In this invention, the large-diameter hole 5.2 inside the sliding sleeve 5, the large-diameter end 9.2 of the sliding rod 9, and the outer diameter of the cylindrical helical compression spring 8 are all clearance-fitted; the small-diameter section 9.1 of the sliding rod 9 and the inner diameter of the cylindrical helical compression spring 8 are clearance-fitted; the cylindrical helical compression spring 8 is installed in the gap formed by the large-diameter hole 5.2 of the sliding sleeve 5 and the small-diameter section 9.1 of the sliding rod 9. On the one hand, the clamping force formed by it with the sliding rod 9 and the sliding sleeve 5 ensures good contact or disengagement between the sliding rod 9 and the through hole c1.1 of the limiting seat 1; on the other hand, it also ensures that the axes of the sliding rod 9 and the sliding sleeve 5 are not skewed, so that the force on the sliding rod 9 and the limiting seat 1 is uniform.

[0020] In this embodiment, after the limiting device is assembled, the fixing plate 3, the rotating shaft 10, the limiting seat 1, and the base 11 of the limiting device are welded together. The limiting device processed in this way will be more flexible and reliable in use.
