[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a transmission line tower lifting device, comprising a body and a roller;

[0005] A roller is provided between the left and right ends of the right inner wall of the machine body, a lifting rope is wound around the outer wall of the roller, a fixing box is provided on the upper side of the machine body, a roller is provided on the lower side of the inner wall of the fixing box, a sinker is provided at the end of the lifting rope, and a hook is provided at the lower end of the sinker, and the hook is used to lift objects;

[0006] A pull rod is inserted into the right side of the fixing box;

[0007] The pull rod is fixed to the inner wall of the fixed box through a fixed axis. The pull rod can rotate with the fixed axis as the base point. A connecting block is provided on the left side of the lower end of the pull rod. A ceramic brake pad is provided on the lower end of the connecting block. When the right side of the pull rod is pulled upward, the left side will move downward so that the ceramic brake pad fits against the outer wall of the roller to brake it.

[0008] Preferably, a counterweight is provided on the right side of the lower end of the pull rod, and the counterweight is used to add weight to the pull rod to make the right side fall down. The right end of the pull rod is sleeved with a rubber sleeve.

[0009] Preferably, the pull rod, the connecting block and the counterweight are all made of steel, and the connecting block and the pull rod are connected and fixed by welding.

[0010] Preferably, two fixing hooks are provided on the upper end of the fixing box, and the two fixing hooks are used to hang and fix the fixing box, and the roller is fixed to the lower side of the inner wall of the fixing box through a rotating shaft.

[0011] Preferably, an oil cap is provided on the left rear side of the upper end of the body, and fuel can be added to the body by opening the oil cap.

[0014] Compared with the prior art, the present invention provides a transmission line tower lifting device with the following beneficial effects:

[0015] When the line tower needs to be repaired and parts need to be replaced, the workers can first bring the fixing box to the tower and hang it on the steel structure of the tower through the fixing hook for fixation, and then fix the machine body to the base at the lower end of the tower through bolts for fixation. When objects are to be hoisted, the objects are hung through the hook, and then the machine body drives the roller to rotate, so that the roller rotates to wrap the lifting rope around the outer wall of the roller to shrink the lifting rope. The contraction of the lifting rope causes the lifting rope to rotate on the outer wall of the roller to drive the objects hoisted on the hook to move upward, thereby achieving the effect of transportation and lifting. When the machine body reels the lifting rope, if the roller accidentally reverses or the lifting rope between the roller and the roller breaks, the hoisted objects will speed up. In the event of an object falling down, the staff can quickly pull up the pull rod. While pulling up the pull rod, the pull rod will rotate with the fixed axis as the base point, thereby driving the connecting block to move downward. As the connecting block moves downward, the ceramic brake pad will fit outside the roller, thereby forming friction with the roller to reduce the speed of the roller rotation until the roller stops rotating. The ceramic brake pad generates friction on the roller to reduce the speed and stop the rotation to fix it. Rapid braking can slow down the falling speed of the object and reduce the impact force when falling, thereby reducing damage to the object and the surrounding environment, stopping the falling of the object, preventing the object from continuing to fall, and avoiding losses caused by damage to the object.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides Figure 1-3 The transmission line tower lifting device shown includes a body 3 and a roller 5;

[0022] The lifting device 11 is fixed on the upper side of the machine body 3, and the lifting device 11 is fixed on the lower side of the inner wall of the machine body 3. The lifting device 11 is fixed on the upper side of the machine body 3, and the lifting device 11 is fixed on the lower side of the inner wall of the machine body 3. The lifting device 11 is fixed on the upper side of the machine body 3, and the lifting device 11 is fixed on the lower side of the inner wall of the machine body 3. The lifting device 11 is fixed on the upper side of the machine body 3, and the lifting device 11 is fixed on the lower side of the machine body 3.

[0023] A pull rod 10 is inserted into the right side of the fixing box 8;

[0024] The pull rod 10 is fixed to the inner wall of the fixed box 8 through the fixed shaft 18. The pull rod 10 can rotate with the fixed shaft 18 as the base point. A connecting block 17 is provided on the left side of the lower end of the pull rod 10. A ceramic brake pad 16 is provided on the lower end of the connecting block 17. When the right side of the pull rod 10 is pulled upward, the left side will move downward so that the ceramic brake pad 16 fits against the outer wall of the roller 11 to brake it.

[0025] The hoisted items will accelerate and fall downward. In this case, the staff can quickly pull up the pull rod 10. While pulling up the pull rod 10, the pull rod 10 will rotate with the fixed axis 18 as the base point, thereby driving the connecting block 17 to move downward. While the connecting block 17 moves downward, the ceramic brake pad 16 will fit onto the outside of the roller 11, thereby forming friction with the roller 11 to reduce the rotation speed of the roller 11 until the roller 11 stops rotating. The ceramic brake pad 16 generates friction on the roller 11 to reduce the speed and stop the rotation to fix it.

[0026] like Figure 2 and Figure 3 As shown, a counterweight 15 is provided on the right side of the lower end of the pull rod 10. The counterweight 15 is used to add weight to the pull rod 10 to allow the right side to fall. A rubber sleeve 14 is provided on the right end of the pull rod 10. The pull rod 10, the connecting block 17 and the counterweight 15 are all made of steel. The connecting block 17 and the pull rod 10 are connected and fixed by welding.

[0027] The rubber sleeve 14 sleeved on the right end of the pull rod 10 will increase the comfort of gripping the pull rod 10. The counterweight block 15 on the right side of the lower end of the pull rod 10 is used to increase the weight of the right side of the pull rod 10. The counterweight block 15 drives the pull rod 10 to fall to the right and prevent the ceramic brake pad 16 on the left from contacting the roller 11.

[0028] like Figure 1 and Figure 2 As shown, two fixing hooks 9 are provided on the upper end of the fixing box 8, and the two fixing hooks 9 are used to hang and fix the fixing box 8. The roller 11 is fixed to the lower side of the inner wall of the fixing box 8 through the rotating shaft 7. An oil cover 4 is provided on the left rear side of the upper end of the body 3. The oil cover 4 can be opened to add fuel to the body 3. Two control buttons 19 are provided on the right front side of the upper end of the body 3. The two control buttons 19 are used to control the device to drive the roller 5 to rotate forward and reverse.

[0029] Bring the fixing box 8 to the iron tower and hang it on the steel structure through the fixing hook 9 for fixation. When the lifting rope 6 is pulled, the roller 11 will rotate through the rotating shaft 7 to drive the lifting rope 6 to move. The control button 19 is used to control the device to drive the roller 5 to rotate forward and reverse, thereby controlling the lifting and lowering of the hook 13.

[0030] like Figure 1 and Figure 2 As shown, fixing blocks 1 are provided on the edges of the front and rear ends and the left and right sides of the body 3, and bolts 2 are provided on the upper ends of multiple fixing blocks 1. The body 3 is fixed to the base of the tower through the bolts 2 on the upper ends of the fixing blocks 1. Handles 20 are provided on the left and right ends of the body 3. The two handles 20 are used to carry the body 3. The lifting rope 6 is made of cotton, linen, and synthetic fibers.

[0031] The machine body 3 is fixed to the base at the lower end of the tower by the bolts 2 at the upper end of the fixing block 1. When transporting the machine body 3, the machine body 3 is pulled by the handles 20 at the left and right ends of the machine body 3 to be transported. The lifting rope 6 made of cotton, linen, and synthetic fibers has stronger tensile strength and toughness.

[0032] The working principle of the utility model is as follows: when the line tower needs to be repaired and parts need to be replaced, the worker can first bring the fixing box 8 to the tower and hang it on the steel structure of the tower through the fixing hook 9 for fixing, and then fix the machine body 3 to the base at the lower end of the tower through the bolt 2 for fixing. When the object is to be hoisted, the object is hung through the hook 13, and then the machine body 3 drives the roller 5 to rotate, so that the roller 5 rotates to wrap the lifting rope 6 around the outer wall of the roller 5 to shrink the lifting rope 6. The contraction of the lifting rope 6 causes the lifting rope 6 to rotate on the outer wall of the roller to drive the object hoisted on the hook 13 to move upward, so as to achieve the effect of transportation and lifting. When the machine body 3 rewinds the lifting rope 6, if an accident occurs and the roller 5 is reversed or When the lifting rope 6 between the roller 11 and the roller 5 breaks, the hoisted items will accelerate and fall downward. In this case, the staff can quickly pull up the pull rod 10. While pulling up the pull rod 10, the pull rod 10 will rotate with the fixed axis 18 as the base point, thereby driving the connecting block 17 to move downward. While the connecting block 17 moves downward, the ceramic brake pad 16 will fit the outside of the roller 11, thereby forming friction with the roller 11 to reduce the rotation speed of the roller 11 until the roller 11 stops rotating. The ceramic brake pad 16 generates friction on the roller 11 to reduce the speed and stop the rotation to fix it. Rapid braking can slow down the falling speed of the item and reduce the impact force when it falls.
