Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a hoisting device for a port cable well bell cover. Background Technology

[0002] Ports are the gathering points and hubs of water and land transportation, distribution centers for industrial and agricultural products and foreign trade import and export goods, and places for ships to berth, load and unload cargo, embark and disembark passengers, and replenish supplies. As the "core operating unit" of a port, the wharf is a specific facility used for ships to berth, load and unload cargo / personnel embark and disembark. In bulk cargo transportation loading and unloading wharves, gantry cranes play a crucial role in loading and unloading tasks. Currently, in the maintenance and repair of gantry cranes, the maintenance of the manhole is crucial. The manhole is usually located below the gantry crane. During the routine maintenance of the cables in the manhole, it may be necessary to open the manhole bell cover to inspect, test, or repair the cables inside. Forklifts can easily lift the manhole bell cover, allowing maintenance personnel to easily enter the manhole for operation. However, the lifting of the forklift relies on a single / two-point connection between the forks or lifting tools and the sling. After the manhole bell cover (mostly irregular heavy objects such as round or rectangular objects) is lifted, the center of gravity may not coincide with the lifting point, resulting in a shift in the center of gravity and poor fixation of the manhole bell cover. Therefore, a manhole lifting device is proposed to solve these thorny problems. Utility Model Content

[0022] Example 1, as Figures 1-6As shown, a port cable well bell jar hoisting device is applied to a forklift 1. The forklift 1 is equipped with two lifting teeth 2. Before hoisting the bell jar 25, the forklift 1 is driven to the port and stopped on one side of the gantry crane. The forklift 1 is close to the well. As a hoisting structure, it includes a mold 3, a clamping mechanism, a fixing plate 5, a mounting plate 6, a rotating mechanism and a hoisting mechanism. A mold 3 is slidably mounted on the tooth 2, and a groove 4 is provided on the mold 3. It should be noted that the tooth 2 is not rectangular, one end of the tooth 2 is streamlined, and the width of the groove 4 is greater than the width of the tooth 2. like Figure 3 As shown, the clamping mechanism is set on the mold 3 to clamp and fix the insert 2. The clamping mechanism includes an abutment plate 7, a threaded rod 8, and a knob 9. The mold 3 has multiple slots. The abutment plate 7 is slidably set in the slots. In order to adapt to the end face of the insert 2 and clamp and fix it, a rubber pad 21 is fixedly set on the abutment plate 7. One end of the threaded rod 8 is rotatably connected to the abutment plate 7. The mold 3 has multiple threaded holes. The threaded rod 8 is threadedly connected to the threaded holes. The other end of the threaded rod 8 is coaxially fixedly connected to the knob 9. By passing the two molds 3 through the two inserts 2 respectively, and then turning the multiple knobs 9, the knobs 9 drive the threaded rod 8 to rotate. The threaded rod 8 rotates and moves toward the insert 2. The threaded rod 8 drives the abutment plate 7 to move toward the insert 2 and, together with the rubber pad 21, clamps the insert 2. Because the rubber pad 21 has good elasticity and toughness, the rubber pad 21 can deform and clamp the insert 2. The threaded rod 8 is threadedly connected to the threaded hole and has self-locking property, which can maintain the stability of the abutment plate 7. like Figure 4 As shown, both molds 3 are fixedly connected to the fixed plate 5. In order to fix the two molds 3 to the fixed plate 5, the two molds 3 and the fixed plate 5 are fixedly connected by two connecting plates 23. This can maintain the integrity of the fixed plate 5 and the two molds 3. The distance between the two pick teeth 2 on the forklift 1 is fixed. The two pick teeth 2 correspond to the two molds 3 respectively. The fixed plate 5 has a snap-fit ​​groove. The mounting plate 6 is rotatably set in the snap-fit ​​groove, which limits the longitudinal movement of the mounting plate 6. A support shaft 24 is rotatably connected to the inner top wall of the snap-fit ​​groove. One end of the support shaft 24 is coaxially fixedly connected to the mounting plate 6, which can limit the movement of the mounting plate 6 and prevent the mounting plate 6 from moving horizontally. In order to allow the mounting plate 6 to be rotatably set in the fixed plate 5, the mounting plate 6 can also be connected to the outside. The snap-fit ​​groove is located in the middle of the fixed plate 5. The fixed plate 5 has a through groove 22. The through groove 22 is circular and its diameter is smaller than the diameter of the snap-fit ​​groove. The through groove 22 and the snap-fit ​​groove are connected. like Figure 1As shown, the rotating mechanism is mounted on the fixed disk 5 and is used to drive the mounting plate 6 to rotate. The rotating mechanism includes a gear ring 10, a connecting frame 11, a rotating shaft 12, a gear 13, and a motor 14. The gear ring 10 is sleeved on the outside of the mounting plate 6 and is coaxially and fixedly connected to the mounting plate 6. The fixed disk 5 is connected to and fixedly mounted with the connecting frame 11. The rotating shaft 12 is rotatably mounted inside the connecting frame 11. The gear 13 is sleeved on the rotating shaft 12 and is coaxially and fixedly connected to the rotating shaft 12. The gear 13 and the gear ring 10 mesh. The motor 14 is mounted on the connecting frame 11. The output end of the motor 14 is coaxially and fixedly connected to one end of the rotating shaft 12. By starting the motor 14, the output end of the motor 14 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the gear 13 to rotate. The gear 13 drives the gear ring 10 to rotate. The gear ring 10 drives the mounting plate 6 and the support shaft 24 to rotate. like Figure 1 and Figure 5 As shown, the hoisting mechanism is mounted on the mounting plate 6 for hoisting the bell jar 25. The hoisting mechanism includes connecting rods 15, hooks 16, fixed seats 17, and retaining rings 18. Multiple connecting rods 15 are evenly distributed around the circumference of the mounting plate 6 to maintain the horizontality and stability of the bell jar 25. The hooks 16 are rotatably connected to the other end of the connecting rods 15 via hinges. The hinges include a hinge frame 19 and a connecting shaft 20. The hinge frame 19 is fixedly connected to the other end of the connecting rods 15, and the connecting shaft 20 is rotatably mounted inside the hinge frame 19. The connecting shaft 20 is rotatably connected to one end of the hooks 16. Multiple fixed seats 17 are fixedly mounted around the circumference of the bell jar 25. The upper rotating part is provided with a retaining ring 18, which is a semi-ring. The retaining ring 18 is detachably engaged with the hook 16. By moving the forklift 1 to one side of the well bell jar 25, the mold 3 and the fixing plate 5 are fixed on the insert 2. The height of the insert 2 is adjusted longitudinally to drive the height of the hook 16, and the multiple hooks 16 are positioned above the multiple retaining rings 18. By rotating the mounting plate 6, the multiple connecting plates 23 and the hooks 16 are rotated, so that the multiple hooks 16 can correspond to and hook the retaining rings 18 when rotating along the connecting shaft 20. This makes the forklift 1 flexible, and the angle of the forklift 1's head is unlikely to affect the installation and removal of the bell jar 25. Working principle: When this port cable hoisting device is used by a forklift 1 to hoist the bell jar 25, the two molds 3 are driven through the two insert teeth 2 by the hand-held fixing plate 5. Then, by turning multiple knobs 9, the knobs 9 drive the threaded rod 8 to rotate. The threaded rod 8 rotates and moves towards the insert teeth 2. The threaded rod 8 drives the abutment plate 7 to move towards the insert teeth 2, and cooperates with the rubber pad 21 to press the insert teeth 2 together. Because the rubber pad 21 has good elasticity and toughness, the rubber pad 21 can deform and press the insert teeth 2 together. The threaded rod 8 is threadedly connected to the threaded hole and has self-locking property, which can keep the mold 3 stably fixed on the insert teeth 2. Then, by adjusting the height of the insert teeth 2 longitudinally, the height of the hooks 16 is driven, and multiple hooks 16 are positioned above multiple retaining rings 18. By rotating the mounting plate 6, multiple connecting plates 23 and hooks 16 are driven to rotate, so that multiple hooks 16 can correspond to and hook the retaining rings 18 when rotating along the connecting shaft 20. This makes the forklift 1 flexible, and the angle of the forklift 1's head is unlikely to affect the installation and removal of the bell jar 25. Furthermore, the setting of multiple hooks 16 and retaining rings 18 can maintain the level and stability of the bell jar 25. Finally, by moving the two insert teeth 2 longitudinally, the bell jar 25 is moved longitudinally, and the movement of the forklift 1 causes the bell jar 25 to move, which allows for the inspection, testing, or repair of cables inside the well. It should be added that the lifting structure in one embodiment is characterized by its lightweight structure, ease of operation, and suitability for the lighter bell jar 25, while the other lifting structure in embodiment two is characterized by its stronger stability and suitability for the heavier bell jar 25.

[0023] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
