Description

Technical Field

[0001] The invention belongs to the field of lowering a cable drum, and in particular relates to a concrete cable drum hanging device. Background Art

[0002] In the construction and maintenance of power lines, the cable drum, as a key fixture, plays an important role in ensuring the stability and load balance of the poles. These cable drums, usually made of high-strength concrete, are designed to fix the cables and effectively transfer the resulting tension to the ground, thereby enhancing the stability of the entire power support structure. The correct installation of the cable drum is crucial. Not only does it require it to be accurately buried on the opposite side of the direction of the wire to maximize its effectiveness, but it also requires the depth of burial to be adjusted according to the specific tension of the cable to ensure good stability under various environmental conditions.

[0003] Traditional cable drum lifting and lowering operations are highly dependent on crane equipment. The process usually involves connecting the crane hook to the pre-set ring buckle on the cable drum, and then using the crane's lifting capacity to smoothly lift the cable drum into the pre-excavated cable pit. This method is very effective in flat and open construction areas, which can significantly improve construction efficiency and reduce the burden of manpower.

[0004] However, when power line construction extends to complex terrain areas such as mountainous areas or narrow roads, traditional crane operation methods face severe challenges. In these environments, the rugged road surface, soft geological conditions and narrow space restrictions make it difficult for cranes to approach the construction site, and even impossible to perform lifting operations safely and effectively. This not only greatly limits the feasibility of construction, but may also lead to project delays and cost increases.

[0005] Faced with this problem, the common alternative is to rely on manpower to carry and lower the cable drum. Workers need to lift the heavy cable drum together and carefully and slowly place it into the cable pit. This process is not only time-consuming and laborious, but also requires high physical strength from workers and poses safety risks. Especially in emergency situations that require rapid deployment, this manual operation method is particularly inconvenient and inefficient. Summary of the invention

[0020] 3) At least one set of first telescopic frames is connected to each side of the support platform. Through the telescopic function of the first telescopic frames, the spacing between the two side brackets can be flexibly adjusted.

When the hook body hooks the ring buckle of the wire pull drum and lifts it upward, one end of the hook body is against the gear lever to close the hook mouth, preventing the wire pull drum from being unhooked during the lifting process. After the wire pull drum is lifted into place, the hanger continues to move downward, and the hook body automatically opens under the action of the tension spring, preventing the operator from going down the pit to remove the hook, thereby improving the efficiency of lifting the wire pull drum and ensuring the safety of the operator's operation.

DETAILED DESCRIPTION

[0035] The following will be combined with the attached Figure 1-Figure 9 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] like Figure 1 , Figure 2 As shown, a concrete cable drum hanging device includes a moving frame 3 and a lifting mechanism 4. Figure 3 As shown, the mobile frame 3 includes two groups of symmetrically arranged brackets 31, the two groups of brackets 31 are respectively located on both sides of the wire pulling pit 1, and the lower part of the bracket 31 is provided with a moving wheel 32. In some environments, both ends of the bracket 31 are provided with telescopic legs (not shown in the figure) to improve the stability of the hanging device when hanging the wire pulling drum; the upper parts of the two groups of brackets 31 are connected by a support platform 33, and a support frame 38 is installed on the support platform 33, such as Figure 5 As shown, the lifting mechanism 4 is installed on the supporting frame 38 , and a sling 41 is connected to the lifting mechanism 4 . A first hook 42 is provided at the lower part of the sling 41 , and the first hook 42 is hung on the ring buckle of the cable drum 2 .

[0038] The lifting mechanism 4 includes but is not limited to a winch, a fall chain, an electric hoist or a rigid chain, such as Figure 5As shown, in this embodiment, the lifting mechanism 4 adopts a winch. Specifically, the lifting mechanism 4 includes a motor, one end of the output shaft of the motor is connected to a reducer through a coupling, the output shaft of the reducer is connected to a drum, and the sling 41 is wound around the drum; when the motor rotates, the drum is driven to rotate through the reducer to realize the lifting and lowering of the first hook 42 at the lower part of the sling 41; in order to ensure the lifting stability of the winch, a brake assembly is installed on one side of the input shaft of the reducer, which effectively prevents the winch from falling out of control when the motor stops suddenly or the load is too heavy;

[0039] In some use environments, such as working environments without electricity or with inconvenient electricity, the lifting mechanism 4 uses a fall chain, and the lifting object can be lifted by manually operating the fall chain. This design ensures the flexibility of operation in these special environments. In other embodiments, in order to reduce the weight of the lifting mechanism 4 and the lifting device as a whole and facilitate the transportation and movement of the lifting device, the lifting mechanism 4 can also use an electric hoist or a rigid chain lifting mechanism.

[0040] like Figure 3 As shown, the bracket 31 adopts a lifting platform structure. In this embodiment, the bracket 31 adopts a scissor-type lifting platform, which is convenient for adjusting the height of the hanging device to lift the cable drum to achieve obstacle-crossing operation. In complex terrains such as mountainous areas and hills, there are often obstacles such as stones on the road surface. At this time, the operator can adjust the height of the scissor-type lifting platform so that the hanging device can smoothly cross the obstacles and accurately hang the cable drum 2 to the predetermined position.

[0041] like Figure 3 As shown, at least one set of first telescopic frames 35 is connected to each side of the support platform 33. The first telescopic frames 35 are scissor-type telescopic frames. In this embodiment, two sets of first telescopic frames 35 are provided on each side of the support platform 33. The other end of the first telescopic frame 35 is connected to the upper part of the bracket 31. Through the telescopic function of the first telescopic frame 35, the spacing between the brackets 31 on both sides is flexibly adjusted. This feature is crucial for the operation of the wire pit 1 with different widths and depths. It allows the operator to quickly adjust the spacing between the brackets 31 according to the actual situation on site, ensuring that the hanging device can be stably supported on the edge of the wire pit 1, thereby improving the operation efficiency and safety. In other embodiments, the first telescopic frame 35 can also adopt a rigid chain or a telescopic sleeve 52 structure.

[0042] like Figure 4 As shown, a pin shaft 36 is provided at the intersection of the first telescopic frame 35, and a screw sleeve 37 is provided on the upper part of the pin shaft 36. A stud 34 is rotatably connected to the support platform 33. The threads at both ends of the stud 34 have opposite rotation directions, and both ends of the stud 34 are threadedly connected to the screw sleeve 37. The extension and retraction of the first telescopic frame 35 is achieved by rotating the stud 34, and the first telescopic frame 35 is effectively prevented from moving again after extension and retraction, thereby ensuring the stability of the mobile frame 3.

[0043] like Figure 2 As shown, a hanger 5 is provided at the lower part of the first hook 42. Figure 8 As shown, the hanger 5 includes a center seat 51, a lifting ring 56 is provided on the upper part of the center seat 51, a first lifting hook 42 is hung on the lifting ring 56, a second lifting hook 57 is provided on the lower part of the center seat 51, and the second lifting hook 57 is hung on the ring buckle of the wire pulling drum 2; support arms 54 are provided at the four corners of the center seat 51, and a push rod 55 is threadedly connected to the end of the support arm 54, and the lower end of the push rod 55 is against the upper surface of the wire pulling drum 2. By adjusting the length of the push rod 55, multi-point support of the wire pulling drum is achieved, thereby effectively preventing the shaking phenomenon that may occur during the lifting process; in addition, when the wire pulling drum needs to be placed at an angle, the inclined lifting of the wire pulling drum can be achieved by adjusting the length of each push rod 55, thereby improving the extremely high flexibility and adaptability of the wire pulling drum lifting operation.

[0044] like Figure 8 As shown, sleeves 52 are rotatably connected at the four corners of the center seat 51, and an adjusting bolt 53 is threadedly connected to one end of the sleeve 52. The support arm 54 is inserted into the sleeve 52 with clearance, so that the angle and length of the support arm 54 can be adjusted. It is suitable for the lifting of cable drums of different sizes and realizes the optimized layout of the support points of the cable drum.

[0045] like Fig. 9 As shown, the second hook 57 includes two symmetrically arranged base plates 571, the lower parts of the two base plates 571 are connected by a lever 573, a hook body 574 is pivotally connected between the two base plates 571, a connecting plate 572 is pivotally connected to the outside of the two base plates 571, the upper end of the connecting plate 572 is fixedly connected to the center seat 51, and the pivot point between the hook body 574 and the base plate 571 and the pivot point between the connecting plate 572 and the base plate 571 are both offset from the center line of the base plate 571, a tension spring 575 is connected to one side of the hook body 574, and the upper end of the tension spring 575 is pivotally connected to the base plate 571. 1 is connected inside. In the initial state, the hook body 574 is turned upward under the tension of the tension spring 575 to open the hook mouth. When the hook body 574 hooks the ring buckle of the wire pulling drum and lifts it upward, one end of the hook body 574 abuts against the stop rod 573 to close the hook mouth, thereby preventing the wire pulling drum from being unhooked during the lifting process. After the wire pulling drum is lifted into place, the hanger 5 continues to move downward. The hook body 574 is automatically opened under the action of the tension spring 575, thereby preventing the operator from going down the pit to remove the hook, thereby improving the efficiency of lifting the wire pulling drum and ensuring the safety of the operator.

[0046] like Figure 6 , Figure 7As shown, a rotating assembly 6 is provided on the support platform 33, and the rotating assembly 6 includes an outer shell 61, and a hollow rotating shaft 62 is rotatably connected inside the outer shell 61, and the sling 41 passes through the inside of the hollow rotating shaft 62, and a worm gear 63 is fixedly connected to the outside of the hollow rotating shaft 62, and a worm 64 is meshed on one side of the worm gear 63, and a hand wheel 65 is connected to one end of the worm 64; a blind plate 66 is fixedly connected to the lower end of the hollow rotating shaft 62, and a second telescopic frame 67 is symmetrically connected to the two sides of the lower part of the blind plate 66. The second telescopic frame 67 adopts a scissor-type telescopic frame or a rigid chain structure. In the present embodiment, the second telescopic frame 67 adopts a scissor-type telescopic frame, and the lower end of the second telescopic frame 67 is connected to the center seat 51; the rotating assembly 6 realizes the adjustment of the angle of the hanger 5, thereby realizing the adjustment of the angle of the wire drum. In addition, in the present invention, a second telescopic frame 67 is arranged between the blind plate 66 and the hanger 5, which realizes the guiding function during the lifting process of the hanger 5, ensures that the hanger 5 remains vertical to the support platform 33, and avoids shaking during the lifting process of the wire drum.

[0047] When the device is in use, the mobile frame 3 is first moved to the upper part of the wire pulling drum, and then the second hook 57 is used to hook the ring buckle on the pulling cable, and the wire pulling drum is lifted by the lifting mechanism 4. During this process, the top rod 55 on the hanger 5 is used to press against the upper surface of the wire pulling drum to ensure the stability of the wire pulling drum lifting. The extension length of the corresponding top rod 55 can also be adjusted according to the inclination angle of the wire pulling drum when installed in the wire pulling pit 1, so that the wire pulling drum is lifted at an inclined angle; after the wire pulling drum is lifted, the gravity of the wire pulling drum drives the second hook 57 to rotate downward, and makes one end of the hook body 574 press against the gear rod 573 to close the hook mouth of the hook body 574; then the mobile frame 3 is used to transport the wire pulling drum 2 to the top of the wire pulling pit 1. During the transportation process, if there are obstacles on the ground that hinder the wire pulling drum, the obstacle can be overcome by raising the height of the bracket 31 or by using the lifting mechanism 4 to continue to lift the wire pulling drum.

[0048] After the wire pulling drum is transferred to the top of the wire pulling pit 1, the lifting mechanism 4 lowers the wire pulling drum 2 into the wire pulling pit 1, and then adjusts the angle of the wire pulling drum 2 by using the rotating component 6 according to the position of the wire pulling drum, and then places the wire pulling drum 2 in the wire pulling pit 1. After the wire pulling drum is placed, the lifting mechanism 4 or the bracket 31 descends, so that the second hook 57 is not subjected to the pulling force of the wire pulling drum 2, and the hook body 574 automatically opens under the action of the tension spring 575, avoiding the operator from going down the pit to remove the hook, thereby improving the efficiency of hanging the wire pulling drum and ensuring the operating safety of the operator.

[0049] The above contents are merely examples and explanations of the structure of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the scope defined by the structure of the invention, they should all fall within the protection scope of the present invention.
