DETAILED DESCRIPTION

[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 in 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] See also Figure 1-13 , a live working installation tool for a sensor, comprising an insulating gripping rod 001, a fastening assembly 100 mounted on the upper end of the insulating gripping rod 001, and an electric control assembly for controlling the operation of the fastening assembly 100;

[0036] The fastening assembly 100 includes a fastening housing 110 fixedly mounted on the end of the insulating gripping rod 001, a gearbox component 120 is fixedly mounted on the front end of the fastening housing 110, a gearbox input shaft 121 is mounted on the rear end of the gearbox component 120, a gearbox output shaft 122 is mounted on the upper end surface of the gearbox component 120, a mounting groove 111 is mounted on the upper end surface of the fastening housing 110, a motor component 130 controlled to start and stop by an electric control component is mounted in the mounting groove 111, the motor component 130 is transmission-connected to the gearbox input shaft 121, and a sleeve component 140 is fixedly mounted on the gearbox output shaft 122;

[0037] In the prior art, the angle sensor 015 is used as follows Figure 1The U-shaped buckle 010 (common technology in the prior art) shown is installed on the power grid equipment. The U-shaped buckle 010 includes a U-shaped lock portion 011 with a U-shaped groove and a screw bolt 012 that can be screwed and telescopically matched in the U-shaped groove. When the angle sensor 015 needs to be installed and fixed to the power grid equipment, the angle sensor 015 is first fixed to the side of the U-shaped lock portion 011 away from the screw bolt 012, and then the screw bolt 012 is inserted into the sleeve member 140 of the utility model. Since the sleeve member 140 generally has a certain depth, such as Figure 6 As shown, after the screw bolt 012 is inserted into the sleeve member 140, the U-shaped buckle 010 and the angle sensor 015 are temporarily fixed on the sleeve member 140, and then the U-shaped buckle 010 and the angle sensor 015 are sent to the predetermined installation position through the transmission of the insulating holding rod 001. After the preset installation part of the power grid equipment is inserted into the U-shaped groove of the U-shaped lock part 011, the motor part 130 is controlled to start through the electric control component (not shown), wherein the electric control component includes wireless or wired control, the wireless control includes a wireless receiving part connected to the motor part 130 and a remote control device for controlling the action of the wireless receiving part (a common technology in the prior art), and the start and stop of the motor part 130 can be conveniently controlled by the remote control device, and the wired control includes a control button arranged at the lower end of the insulating holding rod 001, and the control button is electrically connected to the motor part 130 through a wire, and the control button is controlled by the control button. The button controls the start and stop of the motor component 130. After the motor component 130 is started, it drives the gearbox input shaft 121 to rotate. After the gearbox is adjusted, the gearbox output shaft 122 rotates slowly. The slow rotation of the gearbox output shaft 122 drives the sleeve component 140 to rotate. The slow rotation of the sleeve component 140 drives the screw bolt component 012 to rotate, so that the screw bolt component 012 is locked in the U-shaped groove, so that the U-shaped locking part 011 is stably fixed on the preset installation position. After the U-shaped buckle 010 is locked and fixed on the preset installation position, the sleeve component 140 is removed from the screw bolt component 012 through the insulating gripping rod 001, thereby completing the installation and fixation of the angle sensor 015 on the power grid equipment. When it is necessary to remove the U-shaped buckle 010, the guide component 170 and the sleeve component 140 are inserted into the bolt head 013 position, and the motor component 130 rotates in the opposite direction to loosen the screw bolt component 012.

[0038] During use of the utility model, after the operator sends the angle sensor 015 to the preset installation position through the insulating holding rod 001, the angle sensor 015 can be installed under power through the cooperation of the fastening component 100 and the electric control component, thereby greatly increasing the installation efficiency of the angle sensor 015. At the same time, the insulating holding rod 001 is used to protect the U-shaped buckle 010 and the power grid equipment, which can effectively avoid the risk of electric shock and ensure the safety of the operators. The motor component 130 drives the sleeve component 140 to be screwed, which improves the locking strength of the angle sensor 015 after long-term use, thereby greatly improving the installation quality of the angle sensor 015.

[0039] In the embodiment of the utility model, the upper end of the insulating gripping rod 001 is formed with a first support arm 150, a rotating shaft 151 is fixedly provided on the first support arm 150, a second support arm 160 is fixedly provided at the rear end of the fastening housing 110, a rotating shaft mounting hole 161 is provided on the second support arm 160, the rotating shaft 151 rotates and fits in the rotating shaft mounting hole 161, a plurality of adjustment fixing holes 152 are provided on the side of the first support arm 150, an auxiliary connecting rod 162 that can swing up and down is rotatably provided on the side of the second support arm 160, and the end of the auxiliary connecting rod 162 is fixedly fitted in the adjustment fixing hole 152;

[0040] like Figure 2 and Figure 4 As shown, during the use of the utility model, due to the difference in the actual installation elevation angle of the preset installation position in different workplaces, the elevation angle of the U-shaped buckle 010 needs to be adjusted for better installation, such as Fig.10 Shown is a comparison of the U-shaped buckle 010 before and after the elevation adjustment;

[0041] By rotating the rotating shaft 151 in the rotating shaft installation hole 161, the second support arm 160 can swing up and down, so that the U-shaped buckle 010 can be adjusted to an elevation angle of 180°. When the elevation angle of the U-shaped buckle 010 is adjusted to the right position, the end of the auxiliary connecting rod 162 is installed and matched with the appropriate adjustment fixing hole 152, so that the first support arm 150, the second support arm 160 and the auxiliary connecting rod 162 form a stable triangular structure, so that the insulating holding rod 001 can stably and better deliver the U-shaped buckle 010 to the predetermined installation position;

[0042] The fastening shell 110 can be adjusted to rotate 90° circumferentially on the first support arm 150, so that the opening direction of the sleeve member 140 can be facing different directions such as up, down, left and right, making the application range of the installation tool of the utility model wider and more suitable for different working environments.

[0043] In the embodiment of the utility model, a guide member 170 is fixedly disposed on the upper end surface of the gearbox member 120, a first guide hole 171 is formed on the upper end surface of the guide member 170, a second guide hole 172 is disposed on the inner bottom surface of the first guide hole 171, the diameter of the second guide hole 172 is larger than the first guide hole 171, and the sleeve member 140 is disposed in the second guide hole 172;

[0044] like Figure 5 As shown, by the cooperation of the first guide hole 171 and the second guide hole 172, the sleeve member 140 can maintain the function of rotation while being limited in the second guide hole 172. When the screw bolt member 012 is inserted into the sleeve member 140 of the utility model, the sleeve member 140 has a certain probability of falling off from the gearbox output shaft 122, causing the U-shaped buckle 010 and the angle sensor 015 to fall off from the insulating gripping rod 001. The U-shaped buckle 010 and the angle sensor 015 have a certain weight, and falling may cause personal injury to the operator. In addition, the angle sensor 015 is relatively precise and may be damaged if it falls. Therefore, by the cooperation of the first guide hole 171 and the second guide hole 172, the sleeve member 140 is covered in the second guide hole 172, which eliminates the possibility of the sleeve member 140 falling off from the gearbox output shaft 122 and improves the operation stability.

[0045] In the embodiment of the utility model, the rear end of the guide member 170 is provided with an extension plate 180, and a buckle hole 181 is opened on the extension plate 180. The mounting groove 111 is fixedly covered with a cover plate 112, and a buckle member 113 is formed on the cover plate 112 to buckle and cooperate in the fastening housing 110;

[0046] like Figure 8 As shown, by the mutual buckling cooperation between the buckle member 113 and the buckle hole 181, the connection between the gearbox member 120 and the fastening shell 110 is made tighter, so that the overall force of the utility model is more stable.

[0047] In the embodiment of the utility model, a first through hole 173 and a second through hole 174 are provided at the opening of the first guide hole 171. The first through hole 173 and the second through hole 174 are symmetrical with the screwing bolt 012 as the symmetry axis. A latch 175 for limiting the screwing bolt 012 is inserted into the first through hole 173 and the second through hole 174 respectively.

[0048] like Figure 8 and 9As shown, the screw bolt member 012 includes a bolt head 013 and a bolt rod 014. After the bolt head 013 is inserted into the sleeve member 140 for matching, the screwing of the sleeve member 140 can drive the screw bolt member 012 to rotate and lock. However, although the screw bolt member 012 can be temporarily fixed by inserting it into the sleeve, there is a risk that the screw bolt member 012 will fall off from the sleeve, causing the U-shaped buckle 010 and the angle sensor 015 to fall off the insulating holding rod 001, causing personal injury to the operator. In addition, the angle sensor 015 is relatively precise and can be easily damaged if it falls. Therefore, a latch member 175 is respectively inserted into the first through hole 173 and the second through hole 174. The two latch members 175 are The straight-line distance is greater than the diameter of the bolt rod 014 and smaller than the diameter of the bolt head 013, so that the screwing bolt member 012 is limited in the sleeve member 140 while maintaining the rotation function, eliminating the possibility of the screwing bolt member 012 falling off from the sleeve member 140, and improving the operation stability. In one embodiment, when the angle sensor 015 is stably installed, the pin member 175 can be pulled out from the first through hole 173 and the second through hole 174 through an auxiliary insulating rod. In another embodiment, an insulating pull rope is fixed to the end of the pin member 175. When the angle sensor 015 is stably installed, the pin member 175 can be pulled out from the first through hole 173 and the second through hole 174 through the insulating pull rope.

[0049] In the embodiment of the utility model, a supporting plate 002 is fixedly disposed below the fastening housing 110 , and the supporting plate 002 extends to the left / right side of the fastening housing 110 ;

[0050] During the actual installation process, in order to ensure a better locking effect of the U-shaped lock part 011 on the power grid equipment, a U-shaped lock part 011 may be equipped with multiple screw bolt parts 012. Therefore, in order to improve work efficiency, multiple fastening components 100 can be arranged in parallel on the support plate 002, so that the synchronous operation of multiple bolts can be achieved, with high work efficiency and good work consistency. While improving work efficiency, it ensures that the locking effect of each screw bolt part 012 is consistent, which is beneficial to improving the overall locking stability.

[0051] In the embodiment of the utility model, a first protrusion 114 and a second protrusion 115 are provided on the left side wall of the fastening housing 110, and a third protrusion 116 and a fourth protrusion 117 are provided on the right side wall of the fastening housing 110, wherein the third and fourth protrusions 117 are staggered with the first and second protrusions 115;

[0052] like Fig.11As shown, when multiple fastening components 100 are arranged in parallel, the side surfaces of the multiple fastening components 100 can be stably engaged with each other through the staggered snap-fitting of the third and fourth protrusions 117 with the first and second protrusions 115 (as shown by the dotted lines), so that the installation effect of the multiple fastening components 100 is more stable.

[0053] In the embodiment of the utility model, a through buckle positioning groove 176 is provided on the side wall of the first guide hole 171;

[0054] After the preset installation position is inserted into the U-shaped groove of the U-shaped lock part 011, the lower end of the U-shaped lock part 011 is inserted into the buckle positioning groove 176. When the motor part 130 drives the screw bolt part 012 to tighten, the lower end of the U-shaped lock part 011 will be locked in the buckle positioning groove 176, so that the entire fastening component 100 and the U-shaped buckle 010 are locked. Therefore, during the fastening process of the fastening component 100, the self-supporting force of the motor part 130 is on the U-shaped buckle 010, and the U-shaped buckle 010 is sleeved on the preset installation position of the power grid equipment. That is to say, the supporting force of the fastening component 100 and the U-shaped buckle 010 is actually on the preset installation position, not on the insulating rod, and the insulating holding rod 001 only plays the role of tool straightening and partial support Function: The main focus of the installation tool of the utility model during operation is still on the preset installation position. The U-shaped buckle 010, the screw bolt 012 and the fastening assembly 100 are continuously self-locked with the preset installation position during the tightening process of the installation tool of the utility model. When the operator holds the insulating grip rod 001, he does not need to bear the supporting force of the fastening assembly 100 during operation. The operator holding the insulating rod only needs to correct the relative position of the entire installation tool, thereby greatly reducing the physical exertion of the operator during the operation, which is beneficial to reducing the operating burden of the operator and at the same time improving the stability of the installation operation of the utility model and reducing other circuit accidents caused by accidental touch of the installation tool.

[0055] In the embodiment of the utility model, the insulating gripping rod 001 comprises a telescopic rod, and an extension rod 190 is additionally provided between the fastening housing and the second support arm;

[0056] The telescopic rod can be adjusted and extended according to the insulation requirements of different voltage levels, and installation operations at different heights can be performed, making the operation more flexible. By adding an extension rod 190, the preset installation position can be better inserted into the U-shaped groove of the U-shaped lock part 011 for cooperation.

[0057] In one embodiment, a device such as the following is installed at a preset installation location of the power grid equipment: Fig.13The working target fixing part 016 shown in the figure, the angle sensor 015 is installed in other parts through the U-shaped buckle 010, and then the angle sensor 015 is connected to the target fixing shaft 017 on the working target fixing part 016 through a cable, which ensures the normal operation of the angle sensor and makes the installation process more flexible, so that the installation application range of the installation tool of the utility model is wider, and the target fixing shaft 017 can be selected in different directions and accessory sizes according to the specific conditions of the application site.

[0058] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
