At present, in the equipment for electric power overhaul, most of the equipment is not provided with a lighting device, but in the equipment provided with a lighting device in a small part, the problem that the lighting lamp is not convenient enough in a starting mode usually exists when the equipment is used. And before the detection of the to-be-detected piece is started, the circuit of the lighting lamp is required to be communicated so as to turn on the lighting lamp, and when the lighting device touches the charged to-be-detected piece, the circuit of the lighting lamp is easy to be short-circuited, so that the lighting lamp is damaged. In view of this, the present application discloses an electric power overhaul tool, as shown in fig. 1, and fig. 1 shows an overall schematic diagram of the electric power overhaul tool in an embodiment of the present application. An embodiment of the application provides an electric power overhaul tool, which comprises an illumination component, a detection end and a control end, wherein the illumination component is assembled on an electricity inspection operating rod and is close to the detection end; the lighting assembly comprises a supporting arm 31 and a lighting lamp 311, wherein one end of the supporting arm 31 is rotatably connected to the electricity testing operation rod, and the lighting lamp 311 is installed at the other end of the supporting arm 31. In use, the illumination lamp 311 can be automatically illuminated for illumination by controlling the support arm 31 to rotate a first angle. The following describes the power overhaul tool in detail.

Referring to fig. 1 and 6, fig. 6 shows a schematic diagram of a support arm according to an embodiment of the application. In some embodiments, the power overhaul tool comprises a lighting assembly mounted on an electroscopic joystick; the illumination assembly comprises a support arm 31 rotatably connected to the electricity testing operation rod and an illumination lamp 311 arranged on the support arm 31, and the illumination lamp 311 can be lightened after the support arm 31 axially rotates for a first angle around the electricity testing operation rod.

Specifically, the lighting assembly is installed at the one end that is close to the detection end of the electricity inspection operation rod. The light 311 is installed to support arm 31 one end, and its other end rotates to be connected on the electricity test action bars, and the one end that the light 311 was installed to support arm 31 can rotate certain angle around the electricity test action bars. When the device is used by a detection person, the detection person can select whether to start the lighting assembly according to the external lighting condition in the process that one end of the electricity detection operating rod, which is close to the detection end, extends to an object to be detected. If the detection personnel select to not enable the lighting assembly, the lighting assembly is hidden in the electricity-checking operation rod, and the electricity-checking operation of the whole electricity-checking operation rod cannot be influenced. When the inspector selects to activate the illumination assembly, the end of the support arm 31 provided with the illumination lamp 311 is controlled to axially rotate around the electricity inspection operation rod, and when the support arm 31 rotates to a first angle, the circuit of the illumination lamp 311 which is disconnected is communicated, and the illumination lamp 311 is lightened, so that illumination is performed. By the arrangement, when the illuminating lamp 311 is not lightened, even if the illuminating lamp contacts with a charged piece to be tested, the illuminating lamp 311 is not damaged due to short circuit; meanwhile, in the present application, the illumination lamp 311 is lighted by rotating the support arm 31, so that the convenience of the operation of turning on the illumination lamp 311 can be greatly improved.

As shown in fig. 1 and 6, in the present embodiment, the support arm 31 has a fan-like shape. An illumination hole 312 penetrating in the thickness direction of the support arm 31 is formed at one end of the support arm 31 where the illumination lamp 311 is mounted, and the illumination lamp 311 is fitted in the illumination hole 312. In some other embodiments, the illumination lamp 311 may also be fixedly mounted directly to the surface of the support arm 31.

In some embodiments, the supporting arm 31 may rotate around the circumference of the whole electricity testing operation rod, and a plurality of intervals for controlling the lighting lamp 311 to be turned on and off are arranged on the contact surface of the whole electricity testing operation rod and the supporting arm 31 at intervals around the axis of the electricity testing operation rod, and the plurality of turning-on intervals and the plurality of turning-off intervals are staggered with each other. When a detector needs illumination to perform detection operation, the supporting arm 31 rotates to an opening interval, a circuit of the illumination lamp 311 is communicated, and the illumination lamp 311 is lightened; when the inspection personnel completes the inspection operation, the supporting arm 31 rotates to the off section, the circuit of the illumination lamp 311 is disconnected, and the illumination lamp 311 is extinguished. When the inspector needs to perform the next operation, the supporting arm 31 rotates from the last closing section to the next opening section along the circumferential direction of the electricity inspection operation rod, so as to realize the lighting of the lighting lamp 311. Through such setting, can satisfy the illumination demand of inspector to different angles when improving light 311 switch convenience. The angle through which the support arm 31 rotates from one of the closed sections to one of the open sections adjacent to the closed section is the first angle, and the rotation of the support arm 31 around the electroscopic operating rod is unidirectional.

In other embodiments, the rotation of the support arm 31 about the electroscopic lever is bi-directional. At this time, the number of the opening sections and the closing sections is one, and the opening sections and the closing sections are all arc-shaped. The range value of the closing interval relative to the electroscopic operating rod is the first angle, and when the supporting arm 31 rotates to the opening interval, the illuminating lamp 311 is always in a conducting state when rotating along the arc range of the opening interval. When the support arm 31 rotates reversely from the on interval to the off interval, the illumination lamp 311 is turned off. For example, turning clockwise to turn on, turning counterclockwise to turn off. In a specific embodiment, the range value of the closing interval is between 30 degrees and 60 degrees, and the range value of the opening interval is between 30 degrees and 150 degrees. The maximum range value of the opening interval is a position which forms an included angle of 180 degrees with the initial end of the closing interval.

In a specific embodiment, the range value of the closing interval may be 30 degrees, 45 degrees or 60 degrees, and the range value of the opening interval may be 30 degrees, 90 degrees or 150 degrees.

In other embodiments, the whole electricity testing operation rod is provided with a plurality of support arms 31 at intervals along the circumferential direction, each support arm 31 is provided with a lighting lamp 311, and each support arm 31 can rotate forward and backward within a certain angle range along the circumferential direction of the electricity testing operation rod. Meanwhile, an opening section and a closing section are arranged in the rotatable angle range of each supporting arm 31, and when the supporting arms 31 rotate from the closing section to the opening section, the illuminating lamp 311 is lightened; when the support arm 31 is reversed from the on section to the off section, the illumination lamp 311 is turned off. Through such setting, can guarantee all the time that the inspector is along the illumination demand of whole electricity inspection action bars circumference when improving light 311 switch convenience. The angle through which the support arm 31 rotates from the closing interval to the opening interval is the first angle, and the rotatable angle range of the single support arm 31 can be flexibly set according to actual needs.

It should be noted that, the angle corresponding to each opening section and closing section along the radial direction of the electroscopic operating rod can be flexibly set according to actual needs.

In some embodiments, the rotational control of the support arm 31 may be remotely controlled by a remote control, or other control means. In either way, the rotation control of the support arm 31 may be realized. In the present embodiment, the rotation of the support arm 31 is remotely controlled using a remote controller.

In some embodiments, the support arm 31 is configured with a connecting gear ring 315; the electricity testing operation rod comprises a mounting base 30, the lighting assembly further comprises an output gear 32 rotatably connected to the mounting base 30 and a driving piece 224 mounted on the mounting base 30, and the supporting arm 31 is rotatably connected to the mounting base 30; the driving piece 224 is in transmission connection with the output gear 32, and the supporting arm 31 is in meshed transmission with the output gear 32 through the connecting gear ring 315.

Specifically, one end of the support arm 31 facing away from the illumination lamp 311 is provided with a through annular hole along its thickness direction, and the outer side wall of the annular hole facing away from the illumination lamp 311 and having equal thickness is provided with teeth along its thickness direction, so as to form a connecting gear ring 315. The mounting base 30 is constructed with a through hole 330 penetrating in its thickness direction, the driving member 224 is mounted on one side of the mounting base 30, the output end thereof passes through the through hole 330 on the mounting base 30 and out from the other side of the mounting base 30, and the output gear 32 is in driving connection with the output end of the driving member 224 passing through the mounting base 30. The support arm 31 is rotatably connected with the mounting base 30 by sleeving the connecting gear ring 315 on a mounting column on the mounting base 30, and teeth on the connecting gear ring 315 can be meshed with the output gear 32 for transmission. In use, the driver 224 rotates under the control of a person under test to drive the output gear 32 to rotate, and the output gear 32 is capable of transmitting rotational motion to the connecting gear ring 315 engaged therewith, thereby effecting rotation of the support arm 31. With this arrangement, the driving member 224 drives the rotation of the support arm 31 through the gear, thereby ensuring the reliability of the transmission from the driving member 224 to the support arm 31 and the timeliness of the response of the support arm 31 to the rotation.

Please refer to fig. 2, 3 and 6. In some embodiments, the support arm 31 is provided with a first conductor 314 connected to the illumination lamp 311, a second conductor 341 is disposed at a position where the electricity test operation lever is connected to the support arm 31, and the illumination lamp 311 is turned on when the support arm 31 rotates relative to the electricity test operation lever until the first conductor 314 touches the second conductor 341.

Specifically, one end of the supporting arm 31 connected with the electroscopic operating rod is provided with two first conductors 314, which extend to the illumination holes 312 through the built-in circuits of the supporting arm 31, respectively, and when the illumination lamp 311 is installed in the illumination holes 312, the two first conductors 314 can be respectively communicated with the input and output circuits of the illumination lamp 311. Two conductors two 341 are correspondingly arranged at the connection position of the electricity checking operation rod and the supporting arm 31, and are respectively connected with the output circuit and the input circuit of the power supply. When the support arm 31 is installed on the electricity testing operation rod, the first two electric conductors 314 can rotate relative to the electricity testing operation rod along with the rotation of the support arm 31, and when the support arm 31 rotates to a first angle around the electricity testing operation rod, the first two electric conductors 314 on the support arm 31 can be respectively contacted with the second two electric conductors 341, so that a complete current loop can be formed between the power supply and the illumination lamp 311, and the illumination lamp 311 is lightened along with the current loop; when the lighting assembly stops being used, as the support arm 31 further rotates, the first two conductors 314 are respectively dislocated with the second two conductors 341, so that the current loop between the lighting lamp 311 and the power supply is disconnected, and the lighting lamp is extinguished. With such an arrangement, the illumination lamp 311 can be automatically turned on and off as the support arm 31 rotates, thereby facilitating switching of the illumination assembly.

Referring to fig. 2, 3, 4 and 5, fig. 5 is a schematic diagram of a support column according to an embodiment of the application. In some embodiments, the electroscopic lever further comprises a support column 34 connected to the mounting base 30, and the support arm 31 is sleeved on the support column 34 through a connecting gear ring 315; conductor two 341 is mounted on the outer side wall of support column 34 and conductor one 314 is mounted on the inner wall of connecting ring gear 315.

Specifically, the support column 34 is an inverted "T" shaped convex column, and the large end of the support column 34 is in a flat structure with two opposite planes. The mounting base 30 is configured with a mounting hole 310 penetrating in the thickness direction thereof, and a side of the mounting hole 310 facing the mounting driver 224 is configured with a limit groove 313, the limit groove 313 being adapted to the large end of the support column 34. When in installation, the small end of the support column 34 passes through the assembly hole 310, and the large end is clamped in the limiting groove 313 to limit the support column 34 circumferentially and axially; the supporting arm 31 is sleeved on the small end of the supporting column 34 through the connecting gear ring 315 and is positioned on one side of the mounting base 30, which is away from the limiting groove 313. When the driving member 224 drives the supporting arm 31 to rotate, the supporting arm 31 can axially rotate around the supporting column 34. Through such arrangement, the support arm 31 can be rotatably connected with respect to the mounting base 30, and the support arm 31 does not drive the support column 34 to rotate synchronously during rotation around the support column 34. So that when the first conductor 314 rotated with the support arm 31 is rotated to be in contact with the second conductor 341 fixedly mounted on the support column 34, the illumination lamp 311 can be illuminated; when the first conductor 314 is staggered from the second conductor 341 along with the rotation of the support arm 31, the illumination lamp 311 can be turned off, so that the illumination lamp 311 is turned on or off along with the rotation of the support arm 31.

The side wall of the support column 34 is provided with two wire grooves 343 along the axial direction of the side wall and towards the large end, and the two electric conductors two 341 arranged in the mounting hole 342 can be communicated with a power supply through wires in the wire grooves 343 respectively. Through the arrangement, the two second conductors 341 on the support column 34 can be well contacted with the first conductor 314, so that the reliability of contact connection between the second conductors 341 and the first conductor 314 can be improved, and the timeliness of automatic opening or closing of the illuminating lamp 311 along with the rotation of the supporting arm 31 around the support column 34 is ensured.

It should be noted that, in some embodiments, the mounting hole 342 is a blind hole, and an elastic member is further installed in the mounting hole 342, and the elastic member abuts between the second conductive body 341 and the bottom of the mounting hole 342. When the connecting gear ring 315 is mounted at a small end relative to the support column 34, the elastic member can be pressed by the second conductive body 341 to facilitate the mounting of the support arm 31. By means of the arrangement, the elastic piece can always apply a pushing force to the second conductive body 341 away from the bottom of the mounting hole 342, so that the contact reliability of the second conductive body 341 and the first conductive body 314 is improved.

In some embodiments, the number of support arms 31 is at least two, each support arm 31 corresponding to one support column 34, with at least two support columns 34 spaced about the axis of the mounting base 30. Specifically, each support column 34 is provided with a support arm 31, and each support arm 31 is provided with an illumination lamp 311; one support column 34, one support arm 31, and one illumination lamp 311 constitute one illumination group. At least two light groupings are mounted on the mounting base 30 in spaced relation, each light grouping operating independently and independently of the other. Through such setting, a plurality of illumination groups mutually support for whole electric power overhauls instrument can produce circumference's light along checking the electric operating lever, with the illumination demand of guaranteeing the inspection personnel when the maintenance operation. In one specific embodiment, as shown in fig. 3, the number of support arms 31 and support columns 34 is three, and one-to-one.

Please refer to fig. 2, 3 and 4. In some embodiments, the mounting base 30 is provided with at least two mounting posts 320 protruding therefrom, and the at least two mounting posts 320 are spaced about the axis of the mounting base 30; the lighting assembly further comprises at least two transmission gears 33, wherein the at least two transmission gears 33 are meshed with the output gear 32 for transmission, each transmission gear 33 is sleeved on one mounting column 320, and each transmission gear 33 is meshed with one connecting gear ring 315 for transmission.

When the transmission gears 33 are sleeved on the mounting posts 320, each transmission gear 33 is simultaneously meshed with the output gear 32 and teeth of the connecting gear ring 315. When the driving member 224 is driven, the output gear 32 drives the transmission gear 33 to rotate, and the transmission gear 33 drives the support arm 31 to synchronously rotate. By this arrangement, at least two transmission gears 33 and an output gear 32 constitute a planetary gear, so that the plurality of support arms 31 can be driven to rotate with one output gear 32; meanwhile, the center distance between the supporting arm 31 and the output gear 32 can be increased by arranging the transmission gear 33, so that the plurality of supporting arms 31 can be completely contained in the electricity testing operation rod when the illuminating lamp 311 is turned off, and protection is provided for the illuminating lamp 311. In a specific embodiment, as shown in fig. 3, the number of the transmission gears 33 is three, and each transmission gear 33 corresponds to one lighting group.

Specifically, a connecting hole is formed on one side of the mounting base 30 facing the limiting groove 313, and a threaded hole 345 is formed on the end of the support column 34 facing the small end. After the support column 34 is mounted on the mounting base 30, the mounting base 30 is fixedly mounted at one of the end portions of the mounting gap 35 in the axial direction through the connection hole; the support column 34 is fixedly connected to the other end portion of the installation gap 35 in the axial direction through a screw hole 345. With such an arrangement, the mounting base 30 is fixedly mounted within the mounting gap 35 of the electroscopic lever, which provides space for the receiving placement of the support arm 31 to facilitate providing protection to the illumination lamp 311.
