Description

TECHNICAL FIELD

[0001] The utility model relates to a long rod lifting appliance with adjustable length. BACKGROUND

[0002] In the process of processing copper wire and other rod or wire materials, copper rods of different lengths need to be transferred a lot, which is generally transferred by hoisting. Because the lengths of the rod materials are different, different sizes of carriers are needed when hoisting. If the length of the carrier is too short, the rod material is easy to slide off from both ends due to imbalance, causing safety accidents. If the length of the carrier is too long, the rod material is not supported in the center, which is easy to bend in the transfer process and make the carrier slip off from both ends of the rod material. The use of carriers of different lengths requires a large number of carriers, which is high in cost and inconvenient to use. SUMMARY

[0003] The utility model discloses in order to overcome above -mentioned insufficient, provided a long rod lifting appliance with adjustable length, can adapt to the hoisting of different length's rod material, convenient and fast use.

[0004] In order to achieve this object, the utility model adopts the structure that long rod lifting appliance with adjustable length, including main support, two symmetrical side supports are arranged at both ends of the main support, the side support and the main support are perpendicular to each other, one hook is connected to each end of each side support through a connecting chain, a horizontal connecting pipe is arranged at the end of the hook, the connecting pipe is a hollow pipe body, a screw thread is arranged in the center of the connecting pipe, the connecting pipes on the hooks at the same side are connected to each other through an adjusting rod, and opposite screw threads are arranged at both ends of the adjusting rod.

[0005] A pressing plate is arranged on each side support, and the pressing plate is welded and connected to the side support at both ends. The pressing plate is pressed on the end of the main support and connected to the main support by welding.

[0006] A bracket is arranged below each side support, the bracket is longitudinally concave in cross section, and lifting holes are arranged on both sides of the bracket. The two hooks connected by the side support are respectively sleeved in the two lifting holes of the bracket.

[0007] The length of the connecting pipe is greater than the width of the lifting hole.

[0008] A hoisting frame is arranged in the center of the top of the main support, the hoisting frame is welded to the main support at both ends, and the center is raised.

[0009] The utility model has the advantages that the two brackets for supporting the rod material are connected to the hooks on the same side support at both ends, the distance between the two brackets is adjusted by rotating the adjusting rod to adapt to the length of the rod material, and then the rod material is placed on the two brackets. The rod material is transported as a whole by the crane, which is convenient and fast to use. BRIEF DESCRIPTION OF DRAWINGS

[0010] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0011] Figure 1 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0013] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1 The adjustable long bar lifting device shown includes a main support 1, with two symmetrical side supports 2 at both ends of the main support 1. The side supports 2 are perpendicular to the main support 1. Each side support 2 has a hook 5 connected to both ends by a connecting chain 4. The length of the connecting chain 4 can be changed as needed. The two ends of the connecting chain 4 are connected to the side supports and hooks 5 by threads or other detachable structures. A horizontal connecting tube 6 is provided at the end of each hook 5. The connecting tube 6 is a hollow tube with a thread in the center. The connecting tubes 6 on the hooks 5 on the same side are connected to each other by an adjusting rod 7. The two ends of the adjusting rod 7 have opposite threads. The distance between the two connecting tubes 6 can be controlled and maintained by rotating the adjusting rod 7.

[0016] Each side support 2 is provided with a pressure plate 10. The two ends of the pressure plate 10 are welded to the side support 2. The center of the pressure plate 10 is pressed on the end of the main support 1 and connected to the main support 1 by welding, thereby strengthening the connection between the main support 1 and the side support 2.

[0017] Each side support 2 is provided with a bracket 8 below it. The bracket 8 has a U-shaped longitudinal section. Lifting holes 9 are provided on both sides of the bracket 8. The two hooks 5 connected to the side support 2 are respectively inserted into the two lifting holes 9 of the bracket 8. After adjusting the distance between the two connecting pipes 6 on the same adjusting rod 7 according to the length of the bar, the bar can be placed on the two brackets 8 to stably support bars of different lengths, which is convenient and quick.

[0018] The length of the connecting pipe 6 is greater than the width of the lifting hole 9 to prevent the connecting pipe 6 from sliding out of the lifting hole 9, which would cause the weight of the bracket 8 to act directly on the adjusting rod 7 and damage the adjusting rod 7.

[0019] The main support 1 is provided with a hoisting frame 3 at the top center. The two ends of the hoisting frame 3 are welded to the main support 1, and the center is raised to facilitate hoisting by the crane.

[0020] The connecting pipe 6 can be set as a hollow pipe without threads, and the two ends of the adjusting rod 7 are respectively threaded. The two ends of the connecting pipe 6 are connected to the adjusting rod 7 with nuts of a diameter larger than that of the connecting pipe. The position of the connecting pipe 6 on the adjusting rod 7 can be controlled in sequence. Even if the center of the adjusting rod 7 is deformed, the adjustment function will not be affected.

[0021] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
