Description

Technical fields:

[0001] This utility model belongs to the field of cement pole production, and in particular relates to a cement pole loading and unloading hoisting tool. Background technology:

[0002] Cement poles are equipment used in industries such as power, communications, and railways. They are mainly composed of steel bars and concrete, hence they are also called reinforced concrete cement poles. They are mainly used as overhead line supports in industries such as power, communications, railways, and petroleum.

[0003] After the cement poles are produced, they need to be moved out of the factory using a bridge crane and placed in a centralized location. When ready for sale, the bridge crane is used again to lift them onto transport vehicles for shipment. However, the lifting equipment used in this process is usually a single hook or a double hook, which means that only one or two cement poles can be lifted at a time. This results in low loading and unloading efficiency and high loading and unloading costs. Moreover, the gap between the hook and the hollow cavity of the cement pole is relatively large, which can easily lead to hook detachment accidents, thus posing certain safety hazards. Summary of the Invention:

[0004] The purpose of this utility model is to provide a lifting tool for loading and unloading cement poles, and to overcome the shortcomings of the prior art, which effectively solves the existing problem of low lifting and unloading efficiency of cement poles.

[0005] The present invention relates to a cement pole loading and unloading lifting tool, comprising a pair of upright plates, a plurality of lifting heads being installed at equal intervals along the length direction on the inner sidewall of the upright plates, an auxiliary positioning component being provided on the upright plates, and a lifting ring being installed on the top wall of the upright plates.

[0006] Furthermore, the auxiliary positioning component includes a cantilever, which is provided directly above each of the lifting heads. One end of the cantilever is fixedly connected to the top wall of the upright plate, and a semi-circular clamping plate is installed at the other end of the cantilever.

[0007] Furthermore, the lifting head is cylindrical and is vertically installed on the inner side wall of the upright plate (1).

[0008] Furthermore, a rounded corner is provided at the outer end of the lifting head.

[0009] Furthermore, the lifting head is coaxial with the semi-circular card plate.

[0010] Furthermore, a pair of handles are installed on the outer side wall of the upright plate.

[0011] Furthermore, a pair of lifting rings are installed on the top wall of the upright plate.

[0012] The beneficial effects of this utility model are as follows: The loading and unloading lifting device has a simple structure and is easy to operate. By inserting several lifting heads into the cavities at both ends of the cement pole, the bridge crane can lift several cement poles at a time, thereby improving loading and unloading efficiency and reducing loading and unloading costs. At the same time, the gap between the lifting heads and the hollow cavity of the cement pole is small, avoiding the occurrence of hook detachment accidents, thereby improving the safety of loading and unloading cement poles.

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0019] like Figures 1 to 4 As shown, a cement pole loading and unloading lifting tool includes a pair of upright plates 1. Several lifting heads 2 are installed at equal intervals along the length direction on the inner sidewall of the upright plates 1. An auxiliary positioning assembly is provided on the upright plates 1. A lifting ring 3 is installed on the top wall of the upright plates 1. The auxiliary positioning assembly includes a cantilever 4. The cantilever 4 is provided directly above each of the lifting heads 2. One end of the cantilever 4 is fixedly connected to the top wall of the upright plate 1. A semi-circular clamping plate 5 is installed at the other end of the cantilever 4. The lifting heads 2 are cylindrical and are vertically installed on the inner sidewall of the upright plates 1.

[0020] Specifically, by inserting several lifting heads 2 into the cavities at both ends of the cement pole, several cement poles can be lifted at a time.

[0021] In actual use, the lifting rope on the bridge crane is first connected to the corresponding lifting rings 3 on a pair of upright plates 1. Then, the pair of upright plates 1 are lifted, manually separated, and lowered to both ends of the cement pole 7. During this lowering process, the semi-circular clamping plate 5 in the auxiliary positioning component contacts the body of the cement pole 7 and is matched and fastened to the outer circumference of the cement pole 7. This helps the lifting head 2 to quickly and accurately point to the head of the cement pole 7. The cylindrical lifting head 2 is coaxial with the hollow cavity of the cement pole 7. At this time, two ground workers each push an upright plate 1, so that several cylindrical lifting heads 2 are matched and inserted into the end cavities of several cement poles 7 placed side by side. The outer circumference of the cylindrical lifting head 2 slides and fits against the inner circumference of the end cavity of the cement pole 7, thus minimizing the gap between the two, thereby avoiding the occurrence of hooking accidents and improving the safety of lifting. At this time, the bridge crane can load and unload several cement poles 7 in a single lifting, thereby improving the loading and unloading efficiency.

[0022] like Figures 1 to 4 As shown, a cement pole loading and unloading hoisting tool has a rounded corner at the outer end of the hoisting head 2. The hoisting head 2 is coaxial with the semi-circular clamping plate 5. A pair of handles 6 are installed on the outer side wall of the upright plate 1, and a pair of lifting rings 3 are installed on the top wall of the upright plate 1.

[0023] Specifically, the outer end of the lifting head 2 is rounded so that it can be inserted into the cement pole 7 more accurately and quickly.

[0024] In actual use, the outer end of the lifting head 2 is rounded, which further reduces the contact between the outer end of the lifting head 2 and the end of the cement pole 7, allowing it to be inserted into the cement pole 7 more accurately and quickly, and further improving the installation speed of the lifting equipment; ground workers can pull the handle 6 to facilitate the movement or position adjustment of the upright plate 1; a pair of lifting rings 3 are installed on the top wall of the upright plate 1, which makes the lifting force distribution uniform, and makes the cement pole 7 more stable and safe during the lifting process.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
