Description

Technical Field

[0001] The utility model relates to the technical field of tower cranes, in particular to a tower crane cable loader and a tower crane cable storage machine using the tower crane cable loader. Background Art

[0002] Tower cranes are also called tower cranes. Due to their large operating space, they are mainly used for vertical and horizontal transportation of materials in house construction and installation of building components. In order to control the movement of related devices on the boom, it is necessary to use cables to introduce power from the ground. The cables are usually hundreds of meters long and weigh hundreds of kilograms. When the tower crane is used, if the cables cannot be effectively straightened out when they are returned to the warehouse, they will occupy a large stacking site, which can easily cause the cables to become "tangled" and increase the management cost in the later stage. Therefore, the cables returned to the warehouse must be smoothly arranged and the entire cables must be coiled together, and then hung on a special rack for storage. In addition, no knots or twists are allowed during the coiling process, otherwise the service life of the cables will be affected.

[0003] Since a single cable is long and heavy, it is difficult to organize it in a standardized manner when it is manually wound and stored, and it is time-consuming and laborious. Therefore, in the prior art, a tower crane cable storage machine usually uses a motor to drive the winding drum to rotate and wind the cable. After the storage is completed, the cable is tightly wound on the outer surface of the winding drum and cannot be directly taken out. When storing, the winding drum needs to be placed in a preset position together, and a winding drum is required for each cable, which not only takes up storage space, but also increases storage and transportation costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tower crane cable loader in view of the problem in the prior art that the coiled tower crane cable is inconvenient to be removed from the winding drum, which results in occupying storage space and high storage and transportation costs.

[0005] The technical solution to the technical problem of the utility model is: constructing a tower crane cable loader, including a rotating frame rotatably arranged on a tower crane cable storage machine, two cable bearing surfaces arranged at axially symmetrical positions on the rotating frame, and an assembly and disassembly connecting rod mechanism for quickly adjusting the distance between the two cable bearing surfaces, the rotating frame drives the cable bearing surfaces to rotate to coil the tower crane cable on the outside of the cable bearing surfaces.

[0006] Furthermore, the cable bearing surface is configured as an arc-shaped surface protruding outward; this makes it more convenient for the tower crane cable to be coiled on the two cable bearing surfaces.

[0007] Furthermore, the rotating frame includes a fixed frame rotatably arranged on the tower crane cable storage machine, a movable frame hinged at one end on the fixed frame, and a limiting frame arranged at the ends of the fixed frame and the movable frame, and the two cable bearing surfaces include a first bearing surface arranged on the movable frame and a second bearing surface arranged on the fixed frame; the assembly and disassembly connecting rod mechanism is arranged between the movable frame and the fixed frame; the assembly and disassembly connecting rod mechanism can quickly adjust the movable frame where the first bearing surface is located to rotate around the fixed frame where the second bearing surface is located, thereby adjusting the distance between the first bearing surface and the second bearing surface, so that the cables tightly attached to the two bearing surfaces during winding can be loosened, and then the wound cables can be quickly removed from the two bearing surfaces by using auxiliary tools such as slings, and then transferred to a preset storage position.

[0008] Furthermore, the ends of the fixed frame and the movable frame are provided with limiting grooves matched with the limiting frame, which can position the limiting frame at the ends of the fixed frame and the movable frame to prevent the cables from detaching from the rotating frame during rotation.

[0009] Furthermore, the assembly and disassembly connecting rod mechanism includes an upper connecting rod hinged on the movable frame and located on the inner side of the first bearing surface, and a lower connecting rod hinged on the fixed frame and located on the inner side of the second bearing surface, the upper connecting rod and the lower connecting rod are hinged together, and also include a limit pin connected between the upper connecting rod and the lower connecting rod; the rotation between the upper and lower connecting rods is limited by the limit pin, so that the distance between the movable frame and the fixed frame remains unchanged, thereby ensuring that the distance between the two cable bearing surfaces remains unchanged, and the coiled cable is tightly attached to the cable bearing surface; the limit pin is removed and the upper and lower connecting rods are driven to rotate around the hinge between the two, so that the movable frame rotates around the fixed frame, thereby reducing the distance between the two cable bearing surfaces, and the contact between the cable coiled into a ring shape and the cable bearing surface becomes loose, so that the coiled cable can be easily removed from the two cable bearing surfaces.

[0010] Furthermore, a limit baffle matching the lower link is provided at the hinge of the upper link and the lower link, and the limit pin is arranged below the hinge of the upper and lower links to prevent the upper and lower links from rotating excessively relative to each other and leaving the preset position.

[0011] Furthermore, a limit baffle matching the upper link is provided at the hinge of the lower link with the upper link, and the limit pin is arranged above the hinge of the upper and lower links to prevent the upper and lower links from rotating excessively relative to each other and leaving the preset position.

[0012] Furthermore, a trigger is provided on the limit baffle to facilitate the operation of assembling and disassembling the connecting rod mechanism.

[0013] Furthermore, a trigger is provided on the upper connecting rod or the lower connecting rod to facilitate the operation of assembling and disassembling the connecting rod mechanism.

[0014] Another technical problem to be solved by the utility model is to provide a tower crane cable storage machine in view of the problem in the prior art that it is inconvenient to remove the coiled tower crane cable from the reel, which results in occupying storage space and high storage and transportation costs.

[0015] The technical solution of the technical problem of the utility model is: construct a tower crane cable storage machine, which is applied with the tower crane cable loader.

[0016] The implementation of the tower crane cable loader and the tower crane cable storage machine using the tower crane cable loader of the utility model has the following beneficial effects: by rotatably setting a rotating frame on the tower crane cable storage machine and setting two cable bearing surfaces at the axially symmetrical positions of the rotating frame, the rotating frame can coil the tower crane cable on the outside of the two cable bearing surfaces when rotating; by setting an assembly and disassembly connecting rod mechanism that can quickly adjust the distance between the two cable bearing surfaces, when the rotating frame rotates to coil the cable, the assembly and disassembly connecting rod mechanism can be tensioned to maintain the distance between the two cable bearing surfaces unchanged, so that the cable is tightly attached to the two cable bearing surfaces for coiling, and at this time, the two cable bearing surfaces are tightly supported on the inner circle of the coiled cable; and when the cable needs to be removed, the assembly and disassembly connecting rod mechanism can quickly reduce the distance between the two cable bearing surfaces, so that the two cable bearing surfaces are no longer tightly supported on the inner circle of the coiled cable, and the cable can be conveniently removed and transferred to the storage position, so that storage does not require a winding drum, which can save storage space and reduce storage transportation costs.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figure 2 , 2a As shown in FIG. 1 , in the preferred embodiment of the tower crane cable loader of the utility model, it mainly includes a rotating frame 20, a cable bearing surface 30 and an assembly and disassembly connecting rod mechanism 40. Figure 1 , 1a As shown, the rotating frame 20 is preferably rotatably arranged on the tower crane cable storage machine. Specifically, a flange 11 connected to the coupling 3 on the frame 1 can be arranged at the center position of the rotating frame 20, and the coupling 3 is connected to the motor 2 on the frame 1.

[0030] like Figure 2 , 2aAs shown in Figures 3, 4, 5, 6 and 6a, in a preferred embodiment of the tower crane cable loader of the utility model, two cable bearing surfaces 30 are preferably arranged on the rotating frame 20 at axially symmetrical positions relative to the rotation axis X1 of the rotating frame. Specifically, the cable bearing surfaces 30 can be made of a plate material, and the cable bearing surfaces 30 are preferably arranged as an arc-shaped cylinder protruding outward, and the cross-sectional shape of the arc-shaped cylinder can be a circular arc or an elliptical arc.

[0031] like Figure 2 , 2a As shown in Figure 3, in this preferred embodiment, the rotating frame 20 preferably includes a fixed frame 50, a movable frame 60 and a limiting frame 70, wherein the fixed frame 50 is rotatably arranged on the tower crane cable storage machine, that is, the flange 11 of the rotating frame is arranged on the fixed frame 50, connected with the coupling 3 through the flange 11, and the fixed frame 50 is driven by the motor 2 to rotate relative to the frame 1. One of the two cable bearing surfaces 30 is arranged on the fixed frame 50. Specifically, a fixing rod 51 fixedly connected to the edge of the cable bearing surface can be arranged on the fixed frame 50, so as to reliably fix the cable bearing surface 31 on the fixed frame 50. A rib plate 52 matching the cross-sectional shape of the cable bearing surface 31 can also be arranged on the fixed frame 50 on the inner side of the cable bearing surface, so as to support the cable bearing surface 31 and ensure that the entire cable bearing surface 31 is not easily deformed when the cable 4 is closely attached to the outer side of the cable bearing surface; it is best to arrange the rib plate 52 perpendicular to the central axis X2 of the arc-shaped cylindrical surface of the cable bearing surface. The flange 11 is disposed at one end of the fixing frame 50, and the other end is an open end 54 that cooperates with the limiting frame 70, and the cable bearing surface 31 is just disposed between the open end 54 of the fixing frame and the flange 11. Specifically, an open slot 55 can be disposed at the open end 54 of the fixing frame, and a limiting bolt 56 is disposed in the open slot 55. When the limiting frame 70 is inserted into the open slot 55 of the open end of the fixing frame, the limiting bolt 56 can limit the limiting frame 70 from being separated from the open slot 55.

[0032] like Figure 2 , 2aAs shown in Figures 4 and 5, in this preferred embodiment, the other cable bearing surface 32 of the two cable bearing surfaces 30 is arranged on the movable frame 60. Specifically, a fixing rod 61 fixedly connected to the edge of the cable bearing surface can be arranged on the movable frame 60 so as to reliably fix the cable bearing surface 32 on the movable frame 60. Similarly, a rib plate 62 matching the cross-sectional shape of the cable bearing surface 32 can be arranged on the inner side of the cable bearing surface on the movable frame 60 so as to support the cable bearing surface 30 and ensure that the entire cable bearing surface 32 is not easily deformed when the cable 4 is pressed against the outer side of the cable bearing surface. It is also preferred to arrange the rib plate 62 perpendicular to the arc cylindrical central axis X3 of the cable bearing surface. The movable frame 60 includes a hinged end 63 hinged on the fixed frame 50 and an open end 64 matched with the limit frame 70. The hinged end 63 of the movable frame is arranged close to the flange 11 of the fixed frame. The hinge between the movable frame 60 and the fixed frame 50 is set at a suitable position so that the cable bearing surface 32 on the movable frame and the cable bearing surface 31 on the fixed frame are exactly located at an axisymmetric position relative to the rotation axis X1 of the rotating frame. The open end 64 is also provided with an open slot 65, and a limiting bolt 66 is also provided in the open slot 65. When the limiting frame 70 is inserted into the open slot 65 at the open end of the movable frame, the limiting bolt 66 can limit the limiting frame 70 from leaving the open slot 65.

[0033] like Figure 2 , 2a As shown, in this preferred embodiment, the limiting frame 70 is arranged at the ends of the movable frame 60 and the fixed frame 50. Specifically, the limiting frame 70 may include a main rod 71 and a limiting rod 72 arranged perpendicular to the main rod. The two ends of the main rod 71 are respectively matched with the opening slot 65 of the movable frame and the opening slot 55 of the fixed frame, and two limiting rods 72 are provided, corresponding to the opening slot 65 of the movable frame and the opening slot 55 of the fixed frame, respectively. When the two ends of the limiting frame main rod 71 are matched with the movable frame opening slot 65 and the fixed frame opening slot 55 respectively, the limiting rod 72 is just located on the side of the corresponding opening slot 55, 65 facing the rotating frame rotation axis X1, so as to prevent the limiting frame 70 from being displaced in a plane perpendicular to the rotating frame rotation axis X1 and detaching from the rotating frame 20 when the rotating frame 20 rotates; at the same time, the limiting bolts 56, 66 in the corresponding opening slots can limit the limiting frame 70 from detaching from the opening slots 55, 65 along the rotating frame rotation axis X1, so as to reliably position the limiting frame 70 at the ends of the movable frame 60 and the fixed frame 50. It is best to set the main rod 71 and the limiting rod 62 to a suitable length so that the ends of the main rod 61 and the limiting rod 62 both exceed the outer side of the corresponding cable bearing surfaces 31, 32, so that when the cable 4 is wound on the cable bearing surfaces 31, 32, the limiting frame 70 can prevent the cable 4 from detaching from the cable bearing surfaces 31, 32 in the direction along the rotating frame rotation axis X1.

[0034] like Figure 2 , 2aAs shown in Figures 5 and 6, in this preferred embodiment, the assembly and disassembly link mechanism 40 is arranged between the fixed frame 50 and the movable frame 60, and the distance between the two cable bearing surfaces 31 and 32 can be quickly adjusted by adjusting the distance between the open end 54 of the fixed frame and the open end 64 of the movable frame. The assembly and disassembly link mechanism 40 is preferably arranged to include an upper link 41, a lower link 42, and a limit pin 43 connected between the upper and lower links, wherein one end 41a of the upper link is hinged to the movable frame 60 and the other end 41b is hinged to the lower link 42; one end 42a of the lower link is hinged to the fixed frame 50 and the other end 42b is hinged to the upper link 41. Specifically, the upper link 41 can be hinged to the inner side of the cable bearing surface 32 on the movable frame, preferably hinged to the rib 62 at the corresponding position; the lower link 42 can be hinged to the inner side of the cable bearing surface 31 on the fixed frame, preferably hinged to the rib 52 at the corresponding position. Bolt holes 44 are provided at corresponding positions of the upper and lower connecting rods 41 and 42, and the upper and lower connecting rods 41 and 42 are hinged together by bolts 5. Pin holes 45 cooperating with the limit pin 43 are provided at corresponding positions of the upper and lower connecting rods 41 and 42. When the upper and lower connecting rods 41 and 42 are in the same line, the limit pin 43 can be inserted into the pin holes 45 of the upper and lower connecting rods, so that the upper and lower connecting rods 41 and 42 no longer rotate relative to each other around the hinge, thereby fixing the relative position between the movable frame 60 and the fixed frame 50, so that the distance between the two cable bearing surfaces 31 and 32 no longer changes.

[0035] When the upper and lower connecting rods 41 and 42 are collinear, the distance between the two cable bearing surfaces 31 and 32 is the largest. At this time, the limit pin 43 is inserted, the relative position between the upper and lower connecting rods 41 and 42 is fixed, and the distance between the two cable bearing surfaces 31 and 32 is also fixed; the entire rotating frame 20 is rotated to coil the introduced cable 4 on the outside of the two cable bearing surfaces 31 and 32, and the cable 4 is tightly attached to the outside of the cable bearing surfaces 31 and 32. When the limit pin 43 is removed and the upper and lower connecting rods 41 and 42 are pushed to rotate relative to each other around the hinge, the upper and lower connecting rods 41 and 42 are no longer collinear, the distance between the two cable bearing surfaces 31 and 32 becomes smaller, and the cable 4 coiled on the two cable bearing surfaces 31 and 32 is no longer tightly attached to the outside of the cable bearing surfaces 31 and 32. The coiled cable 4 can be quickly removed using auxiliary tools such as slings.

[0036] like Figure 2 , 2aAs shown in Figures 5, 6, and 6a, in this preferred embodiment, a limit baffle 46 is preferably provided on the upper connecting rod 41, and the limit baffle 46 is provided at the hinge with the lower connecting rod and cooperates with the side surface of the lower connecting rod, and the side surface of the lower connecting rod is parallel to the central axis X4 of the hinge of the upper and lower connecting rods 41 and 42; at the same time, the limit pin 43 is provided below the hinge of the upper and lower connecting rods 41 and 42. Specifically, the limit baffle 46 can be set on the side of the upper connecting rod facing the hinge end 63 of the movable frame. When the hinge of the upper and lower connecting rods 41 and 42 is dragged to move in the direction away from the hinge end 63 of the movable frame, the side of the lower connecting rod 42 gradually approaches the limit baffle 46 around the hinge until the upper and lower connecting rods 41 and 42 are collinear. At this time, the side of the lower connecting rod 42 just cooperates with the limit baffle 46, and the limit baffle 46 can limit the lower connecting rod 42 from further rotating around the hinge. At this time, the upper and lower connecting rods 41 and 42 can be positioned at the collinear position by inserting the limit latch 43. In this way, the upper and lower connecting rods 41 and 42 can be quickly dragged to the collinear position without worrying about excessive force causing the lower connecting rod 42 to rotate beyond the collinear position and needing to be adjusted continuously. In this preferred embodiment, the limit baffle can also be set on the side of the upper connecting rod 41 facing the open end 64 of the movable frame. When the upper and lower connecting rods 41 and 42 need to be dragged to the colinear position, the hinge of the upper and lower connecting rods 41 and 42 needs to be moved toward the direction of the hinge end 63 of the movable frame. The limit baffle 46 can limit the rotation angle of the lower connecting rod 42 relative to the upper connecting rod 41, so that the upper and lower connecting rods 41 and 42 can quickly reach the colinear position without adjustment. The limit baffle can also be set on the lower connecting rod as needed. The limit baffle cooperates with the side of the upper connecting rod, and the upper and lower connecting rods 41 and 42 can also be quickly positioned to the colinear position; at this time, the limit pin is set above the hinge of the upper and lower connecting rods 41 and 42.

[0037] In the above embodiment, it is preferred to set a trigger 47 on the upper connecting rod 41 or the lower connecting rod 42, and by pulling the trigger 47, the upper connecting rod 41 or the lower connecting rod 42 can be driven to rotate around the hinge of the upper and lower connecting rods 41 and 42, so as to realize the rapid adjustment of the distance between the two cable bearing surfaces 31 and 32, which is more labor-saving and convenient to operate. The trigger 47 can also be set on the limit baffle 46 as needed.

[0038] like Figure 1 , 1a As shown, in a preferred embodiment of the tower crane cable storage machine of the utility model, it mainly includes a frame 1, a motor 2 and the tower crane cable loader 10 described in the above embodiment, wherein the tower crane cable loader 10 is rotatably arranged on the frame 1 and driven by the motor 2. In this preferred embodiment, the tower crane cable loader 10 can be connected to the motor 2 through a coupling 3.

[0039] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work, any modifications, equivalent substitutions, improvements, etc. made should be included in the protection scope of the present invention.
