Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction safety, in particular to a transformer anti-falling safety hanging point device. Background Art

[0002] When installing workers on top of the transformer, they need to be equipped with anti-fall hanging point devices to fix the safety belt hooks, thereby providing safety protection for the installation and maintenance personnel. In order to provide anti-fall protection for workers working at heights, the traditional method is usually to set up scaffolding at the maintenance site as a safety belt hanging point, or to use guardrails on the top of the transformer for surrounding protection. However, the above methods are relatively complex in structure and installation, and the disassembly workload is also large. In addition, too many parts such as guardrails will affect the design layout of the transformer, and it will also bring inconvenience to the installation of parts on the upper side of the transformer.

[0003] In order to solve the above-mentioned method, some safety hanging point devices suitable for transformers have appeared in the prior art. For example, a safety belt hanging point device is disclosed in the Chinese utility model patent with the authorization announcement number CN215916268U, which includes support rods on both sides, and the upper end of the support rod is provided with a clamping ring for connecting the horizontal rope, and the lower end of the support rod is provided with multiple clamping plates and fastening bolts for fixing the device to the edge of the steel plate of the transformer or other working platform. Another example is a Chinese utility model with the authorization announcement number CN213185277U, which also discloses a safety anti-falling device for transformer maintenance, which connects the upper ends of the insulating vertical poles on both sides through an insulating cross bar, and the insulating cross bar is provided with a safety device such as an operating safety belt, and the lower end of the insulating vertical pole is provided with a strong magnetic base for adsorption and fixation on the top of the transformer. Another example is a transformer overhaul anti-falling tool disclosed in the Chinese utility model patent with the authorization announcement number CN212347494U, which connects the upper ends of the vertical beams on both sides through a cross beam, and the cross beam is provided with multiple hanging holes for hanging safety devices such as safety belts.

[0004] However, the basic structure of the above-mentioned device is to connect the upper ends of the vertical poles on both sides through a beam or a horizontal rope, and the end of the safety belt can only move along the beam or the horizontal rope, which limits the moving range of the installation belt to a certain extent, and further limits the moving range of the operator. With the development of transformer technology, more and more supporting devices are installed on the upper side of the transformer. In many cases, the operator needs to be able to flexibly change the hanging position of the safety belt to more conveniently complete the installation or maintenance needs. Utility Model Content

The top and surrounding of the adjusting rod 102 are provided with hanging plates 103, and hooks are respectively provided at both ends of the safety belt hanging element 4 to be hung on the corresponding hanging plates 103.

[0028] When the utility model is used, the position of the bottom sleeve 101 can be adjusted according to actual needs. Figure 2 As shown, the utility model is provided with a plurality of mounting plates 201 on the upper side of the transformer oil tank top plate 2, and the lower end of the bottom sleeve 101 of each upright pole assembly 1 can be fixed on any mounting plate 201 by bolts according to actual needs, thereby realizing the position adjustment of the bottom sleeve 101, and the number and position of the mounting plates 201 are designed according to actual needs. In addition, the top of the adjustment rod 102 and the four directions of front, back, left and right are provided with a hanging plate 103, so that the operator can hang the end hook of the safety belt hanging element 4 on the hanging plate 103 at a suitable position according to actual needs, and at the same time, it can better cooperate with the position adjustment of the upright pole assembly 1. Therefore, the utility model can flexibly adjust the position of the upright pole assembly 1 according to actual operation needs, and then flexibly adjust the position of the safety belt hanging element 4 to better meet the installation and maintenance needs.

[0029] like Figures 1 to 7 As shown, the adjusting rod 102 is provided with a plurality of adjusting screw holes 1021 at equal intervals along the height direction, and the upper end of the bottom sleeve 101 is provided with a connecting through hole, a fastening bolt 105 and a fastening nut 106. The fastening bolt 105 passes through the connecting through hole and is threadedly connected with the fastening nut 106. In addition, the fastening bolt 105 simultaneously passes through the adjusting screw hole 1021 of the corresponding height on the adjusting rod 102 to achieve the fixing of the adjusting rod 102 and the bottom sleeve 101. The utility model can adjust the height of the adjusting rod 102 according to actual needs, wherein after the fastening bolt 105 and the fastening nut 106 are removed, the adjusting rod 102 can be moved up and down along the bottom sleeve 101 to adjust the height.

[0030] like Figures 2 to 4 As shown, in one embodiment of the present invention, the hanging plates 103 are all welded and fixed to the upper end of the adjusting rod 102 , so that the height of the mounting belt hanging element 4 is mainly adjusted by adjusting the height of the adjusting rod 102 in this embodiment.

[0031] And as Figures 5 to 7 As shown, in another embodiment of the utility model, the hanging plate 103 can be individually adjusted on the corresponding adjustment rod 102, so that in addition to adjusting the height of the mounting belt hanging element 4 by adjusting the height of the adjustment rod 102, the height adjustment of the hanging plates 103 at both ends of the mounting belt hanging element 4 can also be achieved. In addition, when the present embodiment is used, the operator can also directly hang the end of the safety belt on the hanging plate 103 at a suitable position according to actual needs, and at this time, the height of the hanging plate 103 can also be adjusted according to actual needs. Therefore, when the present embodiment is used, the end of the operator's installation belt is no longer limited to the range of movement along the installation belt hanging element 4. The four hanging plates 103 on the front, back, left and right of the upper end of the adjustment rod 102 can all be used for hanging the end of the safety belt, which can further improve the flexibility of use of the present utility model, especially for the situation where there are relatively more devices on the upper side of the transformer, the operator can more flexibly choose the hanging position of the end of the safety belt according to actual conditions.
