Description

Technical Field

[0001] The utility model relates to the technical field of construction safety auxiliary tools, in particular to a safety belt hanger. Background Art

[0002] With the rapid development of society, power equipment is being replaced. The application of GIS combination electrical appliances in substations has become an unstoppable development trend. The use of new equipment has brought new technical requirements, but also new problems. Generally, the height of 220kV GIS combination electrical appliances is more than 3 meters. According to national safety regulations, workers need to wear safety belts in working environments above 2 meters.

[0003] In recent years, during the infrastructure construction and maintenance operations of substations, it is often encountered that there are no suitable safety belt hanging points in some places (such as GIS body and transformer body), resulting in habitual violations such as hanging the safety belt low and using it high during on-site operations, which poses a hidden danger to the lives of the operators.

[0004] For example, the Chinese patent with the announcement number CN203001736U discloses a safety belt hanging assembly, which can be fixed on any specification of the GIS combination electrical appliance to be tested by setting a detachable combination bottom frame and top frame, and provides a hanging space for the safety belt, thereby improving the safety of workers' operation;

[0005] However, the traditional safety belt hanger has relatively single functions and can only be used on equipment that meets a specific structure (such as channel steel). Most of them are only suitable for use on open AIS equipment (such as disconnectors and busbar bridges), and cannot be used on currently commonly used GIS, transformers and other equipment.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example:

[0036] A seat belt hanger, such as Figure 1-6 As shown, it comprises: a hanging ring 1, an insulating rod 2, a base 3, a rotating plate 4, a one-way telescopic rod 5, a pull belt 6, a positioning bolt 8 and a rotating shaft 9; the pull belt 6 itself can adjust its length.

[0037] The hanging ring 1 is freely (360°) rotated and connected to the upper end of the insulating rod 2. The hanging ring 1 is used to install the safety belt. The base 3 is fixed to the lower end of the insulating rod 2. The rotating plate 4 is rotatably connected to the side wall of the base 3 through the rotating shaft 9. The side wall of the base 3 is provided with four / six / eight positioning screw holes distributed in a circular array around the axis of the rotating shaft 9. The rotating plate 4 is threadedly connected with a positioning bolt 8, which drives the positioning bolt 8 to be threadedly connected to any one of the positioning screw holes, thereby realizing the angle adjustment of the rotating plate 4 relative to the base 3.

[0038] Two raised ears 41 are fixed on the left and right parts of the rotating plate 4 facing away from the base 3. One end of the one-way telescopic rod 5 is hinged between the two ears 41 on the same side. The other end (telescopic end) of the one-way telescopic rod 5 is provided with an inverted hook 51 (similar to a C-shaped structure), and the two one-way telescopic rods 5 are symmetrically arranged.

[0039] The one-way telescopic rod 5 includes a sleeve 52, a sleeve rod 53 and a buckle locking bolt 54. One end of the sleeve 52 is hinged between the two support ears 41. The sleeve rod 53 is linearly slidably matched on the sleeve 52. The buckle locking bolt 54 is threadedly connected to the sleeve 52. The barb 51 is arranged on one end of the sleeve rod 53 away from the sleeve 52.

[0040] like Figure 4 , 5 As shown, a row of one-way latching teeth 531 are disposed on the outer side wall of the sleeve rod 53, and the arrangement direction of the one-way latching teeth 531 is consistent with the movement direction of the sleeve rod 53 relative to the sleeve 52;

[0041] like Figure 6 As shown, the snap-on locking bolt 54 includes a threaded portion and a clamping portion. The threaded portion is threadedly connected to the sleeve 52. The clamping portion moves and cooperates on the threaded portion along the axial direction of the threaded portion. An elastic member is connected between the clamping portion and the threaded portion. The free end of the clamping portion abuts against the one-way clamping tooth 531 under the push of the elastic member.

[0042] It also includes a drawstring 6, both ends of which are provided with a drawstring fixing component 61. The structure of the drawstring fixing component 61 is similar to that of the sleeve rod 53. The drawstring fixing component 61 and the sleeve 52 are linearly slidably matched. The drawstring fixing component 61 is also provided with a row of one-way teeth 531.

[0043] The pull strap fixing component 61 / sleeve rod 53 and sleeve 52 can be selected to cooperate with each other to form a corresponding one-way telescopic rod 5 according to needs.

[0044] Working principle:

[0045] Under normal circumstances, the sleeve rod 53 is pushed to move relative to the sleeve 52 to shorten its length. During this process, the one-way latching tooth 531 is engaged with the free end of the latching portion in one direction. When it is necessary to extend its length, the rotating threaded portion drives the free end of the latching portion to disengage the one-way latching tooth 531, thereby facilitating the sleeve rod 53 to be pulled out of the sleeve 52.

[0046] like Figure 7 As shown, the length of the one-way telescopic rod 5 is adjusted so that the inverted hook 51 at the telescopic end thereof is hung on the channel steel 100 . During this process, the one-way telescopic rod 5 rotates relative to the rotating plate 4 to adapt.

[0047] like Figure 8 , 9 As shown, the sleeve rod 53 can be separated from the sleeve 52, and then the drawstring fixing component 61 at the end of the drawstring 6 can be inserted into the sleeve 52, and the length of the drawstring 6 can be adjusted according to the shape of the channel steel 100, and then the length of the two unidirectional telescopic rods 5 can be adjusted, so that the two unidirectional telescopic rods 5 and the drawstring 6 can be matched and sleeved on the channel steel 100.
