DETAILED DESCRIPTION

[0043] The embodiment of the present invention provides a safety ring installation device, which is used to solve the technical problem that the safety ring cannot be installed under power in the prior art.

[0044] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0047] The existing installation method of the safety ring is to manually tie the safety ring to the installation position with a cable tie or an aluminum cable tie. When the installation position is close to live equipment, in order to ensure the safety of the operators, it is necessary to perform a power outage for installation. However, power outages will not only affect the stable supply of electricity, reduce the satisfaction of electricity users, but also cause huge economic losses. It can be seen that power outage installation of safety rings no longer meets the development needs, so there is an urgent need for a safety ring installation device that can achieve live installation.

[0048] See also Figures 1 to 5 The present invention provides a safety ring installation device, comprising:

[0049] A fixing portion 10, an insulating portion 20 and a pressure shrink band 30; the fixing portion 10 includes a fixing surface 11 and a connecting surface 12, the fixing surface 11 is a concave arc surface adapted to the safety ring 40; the insulating portion 20 is connected to the fixing portion 10 via the connecting surface 12; the pressure shrink band 30 is connected in series with the straight end of the safety ring 40, and is connected to the fixing surface 11 via the safety ring 40.

[0050] It should be noted that the function of the fixing portion 10 is to fix the safety ring 40 on the installation device in an easily separable manner to ensure that after the safety ring 40 is relatively fixed to the installation position, the fixing portion 10 and the safety ring 40 can be separated without contact intervention, such as: they can be fixed by bonding, magnetic attraction, vacuum adsorption, etc.; the fixing surface 11 is connected to the character surface of the safety ring 40 for printing other characters such as the name and number of the power equipment, so as to achieve the relative fixation of the safety ring 40 and the fixing portion 10. The present invention uses a pressure curling belt 30 to bind the safety ring 40 to the installation position. When the pressure curling belt 30 is subjected to pressure that can drive it to deform, it will be triggered to change its state and curl from a straight state to the smallest circle. In order to ensure that the pressure curling belt 30 can be triggered, a certain deformation space needs to be reserved for the pressure curling belt 30. Therefore, the fitting surface on the safety ring 40 for fitting and connecting with the installation position is set to a concave arc surface. Because the safety ring 40 is The metal plate is relatively thin, and the character surface opposite to the bonding surface is a convex arc surface, so the fixing surface 11 is a concave arc surface. In addition, according to different fixing methods, the fixing surface 11 needs to be set accordingly, such as: when the adhesive fixing method is adopted, a recyclable adhesive needs to be coated on the fixing surface 11, and when the vacuum adsorption fixing method is adopted, an adsorption plate or adsorption hole needs to be set on the fixing surface 11; the connecting surface 12 is used to connect with the insulating part 20, and its specific design is compatible with the insulating part 20; the insulating part 20 is the control part that the operator directly contacts, and its function is to effectively isolate the operator from the electric current; because the bonding surface and the character surface of the safety ring 40 are both arc surfaces, the safety ring 40 as a whole presents an arc plate, and the straight end of the safety ring 40 is the end where the straight edges of the bonding surface and the character surface are located; the series connection means that the two straight ends of the safety ring 40 are provided with through holes that are compatible with the pressure shrink belt 30, and the pressure shrink belt 30 is passed through the through holes at the two straight ends. In addition, based on the characteristic that the pressure shrink band can be rolled into a circle, the installation position can be a section of a column or rod or other position that can be wrapped by the pressure shrink band. The optimal installation position is a section of a cylinder or round rod, because the contact area between the cylinder and the round rod and the pressure shrink band is the largest, which can generate sufficient friction to fix the safety ring.

[0051] The beneficial effects of this embodiment are as follows: ① By utilizing the characteristic of the pressure curling belt 30 that it automatically curls under pressure, the safety ring 40 is automatically bound to the installation position, and the current is effectively isolated through the insulating part 20, thereby realizing the live installation of the safety ring 40.

[0052] ② The safety ring 40 is automatically bound by the pressure shrink belt 30, replacing the pure manual binding, the installation process is convenient and simple, and the work efficiency is improved.

[0053] ③ By combining the pressure shrink band 30 with the insulating part 20, the safety ring 40 can be installed when the power equipment is energized, which can reduce the planned power outage time, improve the satisfaction of electricity users, and reduce economic losses.

[0054] ④ It can promptly and quickly carry out safety, health and environmental protection 40 installation of power equipment whose name and number have changed, ensuring the consistency of power equipment drawings and reality and facilitating dynamic management.

[0055] ⑤ The pressure shrink belt 30 can be reused, which reduces the waste of resources and saves costs.

[0056] Specifically, since the existing safety ring 40 is mostly made of iron, in order to quickly fix the safety ring 40 and the fixing part 10 relatively, and improve the durability of the fixing part 10, the fixing part 10 is made of permanent magnetic material, that is, the safety ring 40 is fixed on the fixing surface 11 by magnetic attraction. By using permanent magnetic material, the number of adsorption times of the fixing surface 11 will not be limited, that is, the durability is improved, and by using magnetic attraction, the safety ring 40 only needs to be brought close to the fixing surface 11 to complete the fixing, and the fixing process is fast and simple. In this embodiment, the fixing portion 10 is a hexahedron, whose front surface is a concave arc surface, namely the fixing surface 11, and its rear surface is a plane, namely the connecting surface, and the remaining four surfaces are all planes, and the upper and lower surfaces are parallel to each other and perpendicular to the rear surface, and the left and right surfaces are parallel to each other and perpendicular to the rear surface; the rear surface of the safety ring 40 is a convex arc surface, namely the character surface, which is adsorbed on the front surface of the fixing portion 10, and the front surface of the safety ring 40 is a concave arc surface, namely the fitting surface, and the left and right ends of the safety ring 40 are two straight ends, each of which is provided with two through holes that penetrate the front and rear surfaces, and the left through holes and the right through holes are symmetrical to each other.

[0057] Specifically, since most of the safety rings 40 are installed at a high place far from the ground, in order to easily deliver the safety ring 40 to the installation location, the insulating part 20 is set as an insulating rod, and the insulating rod can easily lift the safety ring 40 to the required height by using its own height, replacing the complicated process of manual climbing installation. For easy carrying, the insulating rod can be set as a telescopic rod.

[0058] Specifically, if the curvature of the safety ring 40 differs greatly, different types of fixing parts 10 need to be adapted. In order to improve convenience and practicality, a first threaded hole is opened on the connecting surface 12; a first external thread adapted to the first threaded hole is set at one end of the insulating rod; the first external thread and the first threaded hole are matched with each other to achieve a detachable connection between the insulating rod and the fixing part 10. In this way, a first threaded hole of the same size is set on different types of fixing parts 10, and different types of fixing parts 10 can be installed on the insulating rod as needed, so that the insulating rod has universality.

[0059] Specifically, in order to enable the operating personnel to have a better installation perspective and to better adjust the direction of force so as to apply forces in different directions to the safety ring 40 and the pressure shrink band 30 to adapt to different installation scenarios, a connecting part 50 for connecting the fixed part 10 and the insulating part 20 is added to the safety ring 40 installation device; the connecting part 50 includes a first connecting member 51 and a second connecting member 52; the first end of the first connecting member 51 is connected to the connecting surface 12 of the fixed part 10, and the second end of the first connecting member 51 is hinged to the third end of the second connecting member 52; the fourth end of the second connecting member 52 is connected to the insulating part 20. In this embodiment, the first connecting member 51 includes a rectangular parallelepiped connecting block 51.1 and a square connecting rod 51.2. The connecting surface 12 of the fixing portion 10 is a plane. The largest surface on the left side of the connecting block 51.1 is aligned and connected with the connecting surface 12. The upper end of the connecting rod 51.2 is vertically connected to the middle position of the right edge of the lower surface of the connecting block 51.1. The lower end of the connecting rod 51.2 is provided with an external gear 51.3 made of a hard material. The second connecting member 52 is a heptahedron structure, which is composed of an isosceles triangle located at the top and a rectangular parallelepiped located at the bottom. The second connecting member 52 The upper part of the second connecting member 52 is provided with an internal gear 52.2 made of soft material, and the internal gear 52.2 is meshed with the external gear 51.3 at the lower end of the connecting rod 51.2, so that the connecting rod 51.2 can rotate left and right relative to the insulating rod, that is, the two largest faces of the connecting block 51.1 are located in the rotation direction of the connecting rod 51.2; the lower part of the second connecting member 52 is provided with a second threaded hole 52.1; the upper end of the insulating rod is provided with an external thread matched with the second threaded hole 52.1, and the second external thread and the second threaded hole 52.1 cooperate with each other to connect the insulating rod with the second connecting member 52. In this way, the angle between the first connecting member 51 and the second connecting member 52 can be controlled and adjusted by the hard external gear 51.3 and the soft internal gear 52.2, so that the operator can press the fitting surface of the safety ring 40 into the installation position in a more labor-saving way and with a better viewing angle by adjusting the angle between the first connecting member 51 and the second connecting member 52, and trigger the pressure curling belt 30 to curl.

[0060] Specifically, the surface of the pressure curling belt 30 is relatively smooth, and the friction between the pressure curling belt 30 and the mounting position and the safety ring 40 is relatively small. During the curling process of the pressure curling belt 30, relative movement is likely to occur, which affects the stability of the binding. In order to prevent the relative movement of the pressure curling belt 30, an anti-sliding block 31 made of a material with greater friction is set in the area opposite to the fixed surface 11 of the pressure curling belt 30, and the friction between the anti-sliding block 31 and the fitting surface of the mounting position and the safety ring 40 prevents the relative movement of the pressure curling belt 30; in order to ensure that the anti-sliding block 31 has a sufficiently large friction area with the fitting surface and the mounting position, the anti-sliding block 31 is set into an arc structure that matches the fixed surface 11, and a through hole that matches the pressure curling belt 30 is set on the anti-sliding block 31 for the pressure curling belt 30 to pass through. In this embodiment, the anti-sliding block 31 is set in the middle position of the pressure curling belt 30, and after the straight ends of the pressure curling belt 30 and the safety ring 40 are connected in series, the anti-sliding block 31 is in the middle position between the two straight ends. In order to ensure the stability of the safety ring 40, a first pressure shrink belt 30.1 is connected in series in the upper through hole of the safety ring 40, and a second pressure shrink belt 30.2 is connected in series in the lower through hole of the safety ring 40. Since the left through hole and the right through hole are symmetrical to each other, the two pressure shrink belts 30 are parallel to each other. By setting two pressure shrink belts 30 to bind the safety ring 40 at the same time, a stronger binding force is provided for the safety ring 40, which can effectively prevent the safety ring 40 from accidentally falling off.
