[0023] Please refer to Figure 1 The utility model provides a kind of corner column pulley, including card seat 1, the top end both sides of card seat 1 are fixedly installed with first support plate 2, the inner side wall of two first support plates 2 is provided with second support plate 3, first roller 4 is rotatably connected between two first support plates 2, second roller 5 is rotatably connected between two second support plates 3, the bottom of second support plate 3 is fixedly connected with top plate 6, the top of top plate 6 is rotatably connected with rotating shaft, rotating shaft is provided with hook 8, hook 8 is rotatably connected with closing handle 10 at opening, torsional spring 11 is sleeved on the rotating shaft, one end of torsional spring 11 is fixedly connected with closing handle 10, and the other end is fixedly connected with hook 8.
[0024] During implementation, if cable line conveying or threading is needed during ground operation, card plate 7 under card seat 1 can be opened and inserted on the base or support column on ground, and further stabilize card seat 1 by clamping the other end of card plate 7 on the bottom end of card seat 1 and clamping clasp 16 on one end of card plate 7 on the card frame 15 on the outer wall of card seat 1;If cable line conveying or threading is needed during high-altitude operation, hook 8 can be hung on the rod or hanging rope in the air, and hook 8 is hung on it by opening closing handle 10, and torsional spring 11 will drive closing handle 10 to rebound, to prevent hook 8 from leaving the track.
[0025] Please refer to Figure 1 And Figure 3 Insertion rod 9 is inserted on rotating shaft, and hook 8 is inserted on rotating shaft through insertion rod 9, and one end of insertion rod 9 is provided with knob 12, and knob 12 is threadedly connected on insertion rod 9.
[0026] In specific implementation, the insertion rod 9 serves to connect the hook 8 and the clamping plate 7, so that the hook 8 can rotate flexibly around the clamping plate 7, and the knob 12 at one end of the insertion rod 9 is threadedly connected to the insertion rod 9, so that the knob 12 can be screwed after the installation of the hook 8 is completed, to prevent the insertion rod 9 from being accidentally pulled out.
[0027] Referring to Figure 3 , the clamping plate 7 is hingedly connected to one side of the bottom end of the clamping seat 1, and the other end of the clamping plate 7 is clamped to the other side of the bottom end of the clamping seat 1.
[0028] In specific implementation, the hinge design at one side of the bottom end of the clamping seat 1 allows the clamping plate 7 to rotate flexibly relative to the clamping seat 1, facilitating the opening of the clamping plate 7 and the connection with the base or support on the ground during ground operation.
[0029] Referring to Figure 2 , the first support plate 2 and the second support plate 3 are both provided with threaded holes 13, and the threaded holes 13 are threadedly connected with bolts 14, and the number of the threaded holes 13 on the second support plate 3 is multiple.
[0030] In specific implementation, the switching of the bolts 14 between different threaded holes 13 can accurately change the relative position relationship between the first support plate 2 and the second support plate 3, thereby adjusting the distance between the first roller 4 and the second roller 5.
[0031] Referring to Figure 4 , one end of the clamping plate 7 is fixedly connected with a clasp 16, and the bottom of the outer wall of one side of the clamping seat 1 is fixedly connected with a clamping frame 15, and the top end of the clasp 16 is clamped in the clamping frame 15.
[0032] In specific implementation, the clamping of the clasp 16 and the clamping frame 15 is a further reinforcement measure for the connection of the clamping plate 7 and the clamping seat 1. During ground operation, after the initial connection of the clamping plate 7 and the clamping seat 1 is completed, the clasp 16 is clamped into the clamping frame 15, forming a locking mechanism, which effectively prevents the clamping plate 7 from rotating or displacing due to accidental stress.
[0033] Working principle: when ground operation is performed to realize cable line conveying or threading tasks, first, the clamping plate 7 under the clamping seat 1 is opened and inserted into the base or support previously set on the ground, then the other end of the clamping plate 7 is clamped to the bottom end of the clamping seat 1, while ensuring that the clasp 16 at one end of the clamping plate 7 can be stably clamped in the clamping frame 15 of the outer wall of the clamping seat 1, thereby achieving further reinforcement of the clamping seat 1 and providing stable foundation support for subsequent cable line operation; in the scenario of high-altitude operation, when cable line conveying or threading operation is required, the hook 8 is used to hang the pulley on the high-altitude rod or hanging rope, and the specific operation is to first open the closed handle 10 connected by the rotating shaft at the opening of the hook 8, and after the hook 8 is hung on the high-altitude object, the torsional spring 11 will drive the closed handle 10 to rebound, thereby effectively preventing the hook 8 from accidentally detaching from the track, ensuring the safety and stability of high-altitude operation.
[0034] In addition, the distance between the first roller 4 and the second roller 5 can be adjusted according to the actual size of the cable to ensure the stability of the cable during transportation. Specifically, the bolt 14 on the first supporting plate 2 is inserted into the corresponding threaded hole 13 on the second supporting plate 3. Since there are multiple threaded holes 13 on the second supporting plate 3, the appropriate threaded hole 13 can be selected flexibly according to the size of the cable. After adjustment, the cable is placed between the first roller 4 and the second roller 5, so that the two rollers can tightly clamp the cable. During the transportation of the cable, the first roller 4 and the second roller 5 will rotate with the movement of the cable, and the rolling friction between the rollers and the cable can make the cable move more smoothly on the set path, thereby efficiently completing the transportation or threading work of the cable.
