Description

Technical Field

[0001] The utility model relates to the technical field of spools, in particular to a new type of spool. Background Technique

[0002] A spool is a tool used for winding metal wires or wire ropes. According to the different materials and specifications of the wire ropes to be wound, the specifications and materials of the spools are also different. Spools for winding steel wires are generally made of steel, while spools for winding cables are generally made of wood or iron with wooden boards. The diameters of the spools used vary according to the diameters of the cables. The larger the cable diameter, the larger the spool diameter.

[0003] The principle of the existing spools is simple and can only perform simple winding functions. The wound steel cables can only be simply fixed on the spools. Since the wound steel cables cannot be disassembled from the spools, the spools need to be transported together during the loading, unloading, and transportation processes, which occupies a large amount of space in the transportation tools, resulting in low transportation efficiency and high transportation costs. Moreover, it is prone to danger, and the wound steel cables are also prone to becoming loose and shapeless, with high costs, low efficiency, and labor-intensive. Although there are detachable spools, the disassembly method is relatively troublesome, with low efficiency and labor-intensive. Therefore, we propose a new type of spool. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of spool to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of spool, comprising:

[0006] End caps, the end caps are divided into a fixed end cap and a detachable end cap, and an expansion mechanism is arranged between the fixed end cap and the detachable end cap for winding the steel cable and facilitating the disassembly of the packed steel cable from the spool;

[0007] A translation mechanism is arranged on one side of the detachable end cap for adjusting the distance between the fixed end cap and the detachable end cap, thereby adjusting the expansion size of the expansion barrel.

[0008] As a specific solution in the technical solution of the present application, a second round hole is arranged at the center of the end cap, a cone is arranged on the side of the end cap facing the expansion barrel, the protruding part of the cone is located in the second round hole, the cone is connected to the end cap through a fixing bolt, a plurality of packing grooves are arranged on the outer wall of the end cap, and a plurality of first round holes are arranged on the outer wall of the detachable end cap.

[0009] As a specific solution in the technical solution of the present application, a mandrel is provided in the second round hole on the end cover. Both ends of the mandrel penetrate through the end cover and extend to the outside. The outer diameter of the protruding part of the cone is equal to the inner diameter of the second round hole provided at the center of the end cover. The inner diameter of the protruding part of the cone is equal to the outer diameter of the mandrel, and the mandrel passes through the cone.

[0010] As a specific solution in the technical solution of the present application, the expansion mechanism includes:

[0011] A swelling barrel arranged between the fixed end cover and the detachable end cover. The swelling barrel is composed of several fan-shaped modules surrounding the mandrel, and an L-shaped notch is provided at the top of the side wall of the fan-shaped module.

[0012] As a specific solution in the technical solution of the present application, the inner wall of the fan-shaped module is concave, and a plurality of hooks are provided on the inner wall. Springs are connected to the hooks, and the other ends of the springs are arranged on the hooks fixedly installed on the outer surface of the mandrel. An oval hole is provided in the upper part of the center of one side of the fan-shaped module.

[0013] As a specific solution in the technical solution of the present application, the inner walls at both ends of the fan-shaped module are set to be beveled, which is convenient for sliding up and down on the outer surface of the cone.

[0014] As a specific solution in the technical solution of the present application, the translation mechanism includes:

[0015] A pull rod arranged in the oval hole. One end of the pull rod is fixed on the fixed end cover, and the other end sequentially passes through the oval hole on the fan-shaped module and the first round hole on the detachable end cover and extends to the outside. A rectangular hole is provided at the other end of the pull rod, and a wedge iron is inserted into the rectangular hole.

[0016] As a specific solution in the technical solution of the present application, the first round hole provided on the detachable end cover corresponds to the oval hole. Both the first round hole and the oval hole are used for passing the pull rod. The packing groove is arranged above the gap between the end cover and the fan-shaped module. The packing groove meets the maximum width formed between the L-shaped notches on the fan-shaped module and is used for passing the packing belt to pack the cable.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] For this new type of spool, the operator hits the large head part of the wedge with a hammer, causing it to move within the rectangular hole in the pull rod, thereby driving the detachable end cap to move linearly along the pull rod towards the fixed end cap. During the horizontal movement of the detachable end cap, the cone is synchronously driven to move linearly along the mandrel, reducing the distance between the cones. As the distance between the cones shortens, the cones squeeze the sector module, causing the bevels on the inner walls at both ends of the sector module to slide upward along the lower part of the outer wall of the cone, increasing the diameter between the sectors, expanding the barrel, winding the steel cable, and passing the packing strap through the packing groove to pack the steel cable;

[0019] At the same time, the operator hits the small head part of the wedge with a hammer, causing it to disengage from the rectangular hole in the pull rod, removing the extrusion of the sector module between the end caps. As a result, the spring will retract. Under the retraction of the spring on the sector module of the mandrel, the diameter of the barrel becomes smaller. Removing the detachable end cap allows the packed steel cable to be removed from the outer wall of the barrel, improving the transportation efficiency of the steel cable and reducing the transportation cost.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-9 shown, the present invention provides a technical solution: a new type of cable reel, mainly including an end cap 1, an expansion mechanism 2, and a translation mechanism 3, which are used to wind the steel cable and disassemble the steel cable from the cable reel, improving the transportation efficiency of the steel cable and reducing the transportation cost.

[0032] In this embodiment, before winding the cable, align the first round hole 104 on the removable end cap 108 with the pull rod 301 fixed on the fixed end cap 102, so that the pull rod 301 passes through the removable end cap 108, and expose the rectangular hole 302 on the side of the removable end cap 108 that does not face the expansion barrel 201. At this time, several sector modules 206 that make up the expansion barrel 201 are located between the cones 106, and the beveled angles on the inner walls at both ends of the sector module 206 are in contact with the outer edge of the cone 106. The pull rod 301 is located at the top of the oval hole 202 on the sector module 206, and there is a certain distance between both ends of the sector module 206 and the end cap 1.

[0033] In this embodiment, when winding the cable, the mandrel 103 is placed on the mounting bracket, and the wedge 303 is inserted into the rectangular hole 302 of the pull rod 301. The operator uses a hammer to forcefully strike the large-head part of the wedge 303 downward. The wedge 303 moves downward within the rectangular hole 302. While the wedge 303 moves downward, the wedge 303 moves the detachable end cap 108 linearly along the pull rod 301 towards the fixed end cap 102. Since the cone 106 is fixed to the detachable end cap 108 through the fixing bolt 105, during the horizontal movement of the detachable end cap 108 along the pull rod 301, the cone 106 is synchronously driven to perform a linear motion along the mandrel 103, thereby reducing the distance between the fixed end cap 102 and the detachable end cap 108, and shortening the distance between the two cones 106. Since the outer wall of the cone 106 is inclined, and the lower parts of the inner walls at both ends of the sector module 206 are beveled, and the bevel acts on the outer wall of the cone 106. When the cone 106 moves horizontally on the mandrel 103, the bevel of the sector module 206 slides upward from the lower part of the outer wall of the cone 106. That is, during the horizontal movement of the detachable end cap 108 along the pull rod 301, the cone 106 squeezes the sector module 206, causing the sector module 206 to expand outward, thereby driving the spring 203 to stretch, and enabling the adjustment of the diameter of the expansion barrel 201. When the bevel of the sector module 206 slides upward from the lower part of the outer wall of the cone 106 to the upper part of the outer wall of the cone 106, the expansion barrel 201 expands. At this time, the pull rod 301 is located at the bottom end of the elliptical hole 202, and the steel cable is wound around the outer wall of the expansion barrel 201.

[0034] In this embodiment, when the steel cable is wound well, the operator passes the packing strap through the packing groove 101 to tightly pack the steel cable. The packing strap passes through the packing groove 101 and is located on the L-shaped notch 204 of the sector module 206. Since the L-shaped notch 204 is provided at the top end of the side wall of the sector module 206, the packing strap can pass through the inside of the wound steel cable and then be taken out. Then, the operator uses a hammer to forcefully strike the small head of the wedge 303 to knock the wedge 303 out of the rectangular hole 302 in the pull rod 301. Since the wedge 303 is removed, the spring 203 acting on the inner walls of the mandrel 103 and the sector module 206 retracts. The retraction of the spring 203 drives the bevel on the sector module 206 to slide from the high position of the outer wall of the cone 106 to the low position, thereby reducing the diameter of the expansion barrel 201. At this time, the pull rod 301 is located at the top end of the elliptical hole 202. Then, the detachable end cap 108 is removed, and the steel cable is taken out from the expansion barrel 201, which is convenient for transporting the steel cable.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
