[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0021] The present invention will be further described below with reference to the embodiments.
[0022] Example: Refer to Figures 1 to 2 A power transmission line construction lifting device includes a housing 1, a movable lifting ring 2 fixedly connected to the upper surface of the housing 1, a limit block 3 fixedly connected to the inner wall of the bottom end of the housing 1, and an adjustment mechanism 4 provided on the inner wall of the housing 1.
[0023] The adjusting mechanism 4 includes a bidirectional screw 41 rotatably connected to the inner wall of the housing 1. One end of the bidirectional screw 41, away from the housing 1, passes through a limiting block 3 and the inner wall of the other side of the housing 1, and is fixedly connected to an adjusting knob 42. Two symmetrical threaded blocks 43 are threadedly connected to the rod wall of the bidirectional screw 41. A sliding groove is formed on the inner wall of the bottom end of the housing 1. The outer walls of both threaded blocks 43 are slidably connected to the inner walls of the sliding groove. Threaded sleeves 44 are fixedly connected to the lower surfaces of both threaded blocks 43, and movable hooks 45 are fixedly connected to the lower surfaces of both threaded sleeves 44. Limited... The two limiting rods 5 are slidably connected to the walls of two limiting sleeves 6. The lower surfaces of the two limiting sleeves 6 are fixedly connected to the upper surfaces of two threaded blocks 43. The lower surface of the housing 1 is provided with an anti-sway mechanism 7. The outer wall of the movable lifting ring 2 is provided with two symmetrical clamping plates 8. The inner walls of the two clamping plates 8 are provided with bolt holes, and the bolt holes of the two clamping plates 8 are connected by fastening bolts, which can be used for different models of external lifting devices. The movable hook 45 is made of high-strength alloy wire. The movable hook 45 is of the spring-locking tongue type. The spring-locking tongue type self-locking device consists of a locking tongue, a spring, and a control mechanism. The locking tongue is installed at the hook opening via a pivot. A spring provides elasticity to the locking tongue, allowing it to automatically reset and block the opening, preventing the suspended object from accidentally falling. The cable reel 75 is a small electric cable reel, consisting of a bracket, a pivot, and a cable reel fixing device. The cable reel 75 supports the cable reel. The tension adjustment mechanism can adjust the cable tension hydraulically or mechanically to ensure the cable maintains appropriate tightness during deployment. The braking locking device can quickly stop the cable deployment when needed. The cable reel 75 is a well-known technology in the prior art and will not be described in detail here.
[0024] The anti-sway mechanism 7 includes a fixing block 71 fixedly connected to the lower surface of the housing 1. A latch 72 is fixedly connected to the lower surface of the fixing block 71. An anti-detachment buckle 73 is provided on the inner wall of the latch 72. A limiting post 74 is fixedly connected to the bottom inner wall of the latch 72. A cable feeding frame 75 is fixedly connected to the outer wall of each of the two movable hooks 45. A cable 76 is movably wound around the inner wall of the cable feeding frame 75. The other end of the cable 76 is sleeved with the outer wall of the limiting post 74. The limiting post 74 fixedly connected to the bottom inner wall of the latch 72 is sleeved with the cable 76. With the cable feeding frame 75 winding the cable 76, the position of the cable 76 can be precisely limited, preventing the line from swaying during the lifting process due to external factors, and reducing the occurrence of safety hazards.
[0025] The working principle of this utility model is as follows:
[0026] First, the construction worker rotates the adjustment knob 42, which drives the bidirectional screw 41 to rotate. Since the bidirectional screw 41 is threadedly connected to two symmetrical threaded blocks 43, and the outer wall of the threaded blocks 43 is slidably connected to the groove on the inner wall of the bottom end of the housing 1, when the bidirectional screw 41 rotates, the two threaded blocks 43 move relative to or away from each other along the groove, thereby moving the threaded sleeve 44 and the movable hook 45 fixed to the lower surface of the threaded blocks 43. This allows for adjustment of the distance between the two movable hooks 45 to accommodate the lifting needs of cables 76 of different specifications and spacings. The movable lifting ring 2 of the cable lifter is then installed on the lifting equipment, utilizing the movable... Two symmetrical clamping plates 8 are installed on the outer wall of the lifting ring 2. The clamping plates 8 are tightly clamped at the connection part of the lifting equipment by fastening bolts through the bolt holes on the inner wall of the clamping plates 8. Then, the cable 76 in the cable release frame 75 is released and one end of it is wrapped around the limiting post 74 to make it taut. This limits the two movable hooks 45 and effectively prevents the cable from shaking due to external factors during the lifting process, thus reducing the occurrence of safety hazards.
[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
