Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting devices, and in particular relates to a hoisting frame for hoisting and transporting copper strip coils. Background Technology

[0002] During the hoisting and transportation of copper strip coils, due to their large weight and volume, traditional hoisting frames are prone to slippage, causing safety hazards and material loss. Existing hoisting frames typically lack effective anti-slip structures, easily leading to safety accidents. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a lifting frame for lifting and transporting copper strip coils, which prevents the coils from slipping during transportation, reduces safety hazards, and improves the safety of lifting and transport operations.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a lifting frame for lifting and transporting copper strip coils, comprising a vertical rod, and a top rod and a bottom rod located at the upper and lower ends of the vertical rod. The top rod is provided with a lifting ring for connecting to a crane hook, and a counterweight is provided at the end away from the vertical rod. The vertical rod, bottom rod, and top rod surround and form a loading space for loading the coil. The bottom rod is provided with several stop platforms on the side away from the vertical rod. A telescopic channel is provided on the bottom rod, and the bottom of the telescopic channel is closed. The bottom of the stop platforms is at least partially limited and installed within the telescopic channel, and the stop platforms can move up and down along the telescopic channel. A compression spring is provided within the telescopic channel. One end of the compression spring abuts against the bottom of the telescopic channel, and the other end abuts against the bottom of the stop platforms. When the coil is lifted and loaded, a squeezing force is generated to compress the stop platforms into the telescopic channel, and the compression spring generates an elastic force to prevent the stop platforms from entering the telescopic channel.

[0005] Preferably, the stop platform can be a single stop platform or a stop group composed of multiple stop platforms arranged in parallel along the width direction of the bottom rod.

[0006] Preferably, the base rod has a telescopic groove, which includes a movable groove and a limiting groove. The movable groove is located at the top of the base rod, and the limiting groove is located at its bottom. The stop plate is inserted into the movable groove, and the limiting plate is located at its bottom. The maximum width of the limiting plate is greater than the width of the stop plate, so as to restrict the separation of the stop plate from the telescopic groove. The bottom of the limiting groove has a base platform, and the groove walls of the movable groove and the limiting groove, together with the base platform, form the telescopic channel.

[0007] Preferably, the base is a cover plate that can be detachably installed at the bottom of the base rod, and the two ends of the compression spring press against the cover plate and the stop plate respectively.

[0008] Preferably, the bottom of the limiting groove is provided with the mounting groove, and the cover plate is fixedly installed in the mounting groove. The minimum width of the cover plate is greater than the maximum width of the limiting groove, and the minimum width of the limiting groove is greater than the maximum width of the movable groove. The stop table can be separated from the bottom rod after passing through the limiting groove and the mounting groove.

[0009] Preferably, the top of the cover plate is provided with a guide post, and the bottom of the stop platform is provided with a guide hole. The guide post extends into the telescopic channel and is at least partially inserted into the guide hole.

[0010] Preferably, the top of the stop platform is provided with an arc-shaped platform on the side away from the vertical rod, and the bottom end of the arc-shaped platform is not higher than the slot of the telescopic channel.

[0011] Preferably, the arc-shaped platform is provided with rolling elements, and multiple rolling elements are provided along the arc surface of the arc-shaped platform.

[0012] Preferably, the top of the stop platform has a rounded chamfer on the side facing the vertical rod, and the top end of the rounded chamfer is higher than the slot of the telescopic channel.

[0013] Preferably, the top rod, the vertical rod, and the inner wall of the vertical rod facing the loading space are all covered with a rubber layer.

[0014] The technical effects of this utility model are as follows: 1. By installing an elastic stop plate on the outside of the base rod, a dynamic limiting barrier is formed for the copper strip coil. When the coil is hoisted and placed, its own weight presses down on the stop plate and compresses the spring, causing the stop plate to sink adaptively, ensuring that the coil falls completely into the loading space; when the hoisting frame is lifted off the ground or shaken, the spring rebounds and pushes the stop plate to quickly return to its original position, forming a mechanical block from the bottom outer edge of the coil, effectively preventing the coil from sliding outward, completely eliminating the risk of slippage caused by the coil rolling or tilting in traditional hoisting frames, and effectively reducing safety hazards.

[0015] 2. The design of the arc-shaped platform of the stop table and the rolling parts on it allows the roll material to slide smoothly along the arc surface during the initial loading stage, avoiding bumps and damage. 3. Ensure that the bottom end of the curved platform is not higher than the opening of the expansion channel to ensure that there are no exposed protrusions interfering with the stacking after the roll material is pressed in.

[0016] 4. The rounded chamfer structure provides guidance and cushioning during unloading of the roll material, preventing edge scratches.

[0017] 5. Combined with the rubber layer covering the inner wall of the top rod and vertical rod, a three-dimensional flexible protection system is formed, which takes into account both the scratch prevention of the copper strip surface and the stability of hoisting. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0023] like Figures 1-3 As shown, a lifting frame for hoisting and transporting copper strip coils includes a vertical rod 1, a top rod 2, and a bottom rod 3. The vertical rod 1, top rod 2, and bottom rod 3 are integrally formed and form a "C"-shaped frame. The top rod 2 and bottom rod 3 are located at both ends of the vertical rod 1 and are perpendicular to the vertical rod 1 and bottom rod 3. A lifting ring 4 is integrally fixed to the top of the top rod 2 for connecting to the hook of a crane. A counterweight is provided at the end away from the vertical rod. Furthermore, the top rod 2, the vertical rod 1, and the inner wall of the vertical rod 1 facing the loading space are all covered with a rubber layer.

[0024] Furthermore, a stop platform 6 is provided on the bottom rod 3, and a telescopic groove 5 is provided on the bottom rod 3. The telescopic groove 5 is a stepped groove composed of a movable groove 51 and a limiting groove 52. The movable groove 51 is opened at the top of the bottom rod 3, and a limiting groove 52 is opened at its bottom. The stop platform 6 is inserted into the movable groove 51, and a limiting platform 61 is provided at its bottom. The maximum width of the limiting platform 61 is greater than the width of the stop platform 6, so as to restrict the separation of the stop platform 6 from the telescopic groove 5.

[0025] Furthermore, the bottom of the limiting groove 52 is provided with a base platform, and the groove walls of the movable groove 51 and the limiting groove 52 and the base platform surround the telescopic channel to allow the stop platform 6 to telescopically move.

[0026] Specifically, the base is a cover plate 7, and the bottom of the limiting groove 52 is provided with the mounting groove 71. The cover plate 7 is fixedly installed in the mounting groove 71. Furthermore, the widths of the mounting groove 71, the limiting groove 52, and the movable groove 51 decrease sequentially, and the stop table 6 can pass through the limiting groove 52 and fall out of the mounting groove 71.

[0027] Furthermore, the top of the cover plate 7 is provided with a guide post 8, and the bottom of the stop platform 6 is provided with a guide hole. The guide post 8 extends into the telescopic channel and its top is fitted into the guide hole. A compression spring 81 is sleeved on the guide post 8. One end of the compression spring 81 presses against the cover plate 7, and the other end presses against the bottom of the stop platform 6. When the roll material is hoisted and loaded, a squeezing force is generated to compress the stop platform 6 into the telescopic channel, and the compression spring 81 generates an elastic force to prevent the stop platform 6 from entering the telescopic channel.

[0028] Furthermore, the top of the stop platform 6 extends above the top rod 2, and an arc-shaped platform 62 is provided on the side away from the vertical rod 1. The bottom end of the arc-shaped platform 62 is lower than the groove of the telescopic channel to facilitate the extrusion and insertion of the roll material. Rolling elements are provided on the arc-shaped platform 62, preferably rollers 63. Multiple rolling elements are provided along the arc surface of the arc-shaped platform 62. The top of the stop platform 6 has a rounded chamfer 64 on the side facing the vertical rod 1. The top end of the rounded chamfer 64 is higher than the groove of the telescopic channel to ensure that there is a certain height of blocking surface to prevent the roll material from being exposed while facilitating the separation of the lifting frame and the roll material.

[0029] In other embodiments, there may be multiple stop platforms 6, which form a stop group arranged in parallel along the width direction of the base rod 3. Under the premise that the width of the base rod 3 remains unchanged and the rigidity and strength of the parts are sufficient, the reliability of the stop function of the stop platform 6 is improved by sacrificing a certain service life of a single stop platform 6, so as to avoid the failure of a single stop platform, thus avoiding the occurrence of accidents and further reducing safety hazards.

[0030] The specific implementation process of this utility model is as follows: When loading the roll material, the lifting frame is squeezed and inserted into the central hole of the roll material drum. The roll material is squeezed over the rotating platform and inserted into the area between the vertical rod 1 and the stop platform 6. The stop platform 6 will prevent the roll material from sliding out. When it is necessary to unload the roll material, the bottom rod 3 is lowered and separated from the drum. The stop platform 6 is withdrawn from the central hole of the roll material drum along with the lifting frame.

[0031] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
