DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1 - Figure 7 , an electrical equipment maintenance device with image presentation, including: a stepper motor 42, a rotating part of the stepper motor 42 is connected to a hydraulic cylinder 5 through a rotating shaft 43.

[0033] The cylinder 77 is connected to the top of the telescopic end of the hydraulic cylinder 5. A plurality of second sleeves 79 are connected to the side of the cylinder 77. Adjacent second sleeves 79 form a group. A group of second sleeves 79 is rotatably connected to a second rotating rod 76. There are two second rotating rods 76 in total. The two second rotating rods 76 are symmetrically distributed along the axis of the cylinder 77. Each second rotating rod 76 is connected to the first rotating rod 74 through a rocker rod 75. The first rotating rod 74 is connected to the slider 72 through the first sleeve 73. The top of the slider 72 is connected to a clamping arm 71. A channel 8 is provided on one side of the slider 72. The hydraulic cylinder 5 controls the spacing between the two clamping arms 71 through the telescopic movement of the telescopic end. The stepper motor 42 rotates at the same angle each time, and the angle of each rotation is 25°-95°.

[0034] By extending and retracting the hydraulic cylinder 5, the distance between the top of the telescopic end of the hydraulic cylinder 5 and the support rod 65 is changed. Since the slider 72 can only slide along the axial direction of the support rod 65 and the length of the rocker arm 75 is fixed, when the telescopic end of the hydraulic cylinder 5 descends, the first rotating rod 74 and the second rotating rod 76 both rotate, and the slider 72 moves toward the direction close to the central axis of the support rod 65. The two sliders 72 approach each other, and the two clamping arms 71 are tightened, so that the clamping arms 71 can clamp the inspection object (mostly loose bolts).

[0035] When the stepper motor 42 rotates at an angle of 25° each time, the angle of rotation is small, the rotation amplitude is small, and the time used for one rotation is short. The hydraulic cylinder 5 can be cooperated with to clamp the object under inspection through the clamping arm 71, and the stepper motor 42 can drive the clamping arm 71 and the object under inspection to rotate and tighten in turn, and then the clamping arm 71 releases the object under inspection and clamps the object under inspection again, and the stepper motor 42 rotates again, which saves rotation time, has a higher rotation frequency, and has a better tightening effect.

[0036] When the stepper motor 42 rotates at an angle of 95° each time, the object under inspection is more loose, and the tightness of the object under inspection is greatly improved after one rotation, thereby reducing the number of rotations and increasing the service life of the stepper motor 42.

[0037] The support rod 65 is slidably connected to the slider 72 , and the slider 72 moves along the axial direction of the support rod 65 .

[0038] The moving direction of the slider 72 is limited by the support rod 65 , so that the slider 72 can only move along the axial direction of the support rod 65 .

[0039] The side panels 62 are two in total, and both ends of the support rod 65 are respectively connected to the adjacent sides of the two side panels 62 . A light 91 is connected to the side of one side panel 62 , and a camera 92 is connected to the side of the other side panel 62 .

[0040] The lamp 91 is used to provide lighting for the maintenance environment, and the camera 92 is used to take images of the maintenance object and its surrounding environment in real time, and transmit the images to the display screen of the control panel 2, so that the staff can understand the maintenance environment and maintenance problems.

[0041] The fixed part of the stepper motor 42 is connected to the bottom rod 1, the side of the bottom rod 1 is connected to the control panel 2, the bottom rod 1 is movably connected to the telescopic rod body 31, a circular hole 32 is opened at the center of the top of the telescopic rod body 31, a connecting rod 41 is arranged above the control panel 2, the bottom end of the connecting rod 41 extends into the circular hole 32 and is fixedly connected to the circular hole 32, a plurality of support rods 33 are connected to the edge of the top of the telescopic rod body 31, the plurality of support rods 33 are equidistantly distributed in the circumferential direction of the telescopic rod body 31, and a support ring 34 is connected to the top of the support rod 33.

[0042] The control panel 2 is provided with a plurality of buttons, which are respectively used to control the opening and closing of the hydraulic cylinder 5, the stepping motor 42, the light 91 and the camera 92.

[0043] The integral component carried by the clamp arm 71 is located at the head of the entire device. The head is heavy. If it is suspended in the air for a long time, it only relies on the piston rod of the hydraulic cylinder 5 as the supporting end. The piston rod is continuously under pressure, the working intensity is high, and it is easy to cause the piston rod to bend or be damaged. A support ring 34 is added as a supporting platform, and the support ring 34 is used as the main supporting member to support the integral component where the clamp arm 71 is located. The support ring 34 is slidably connected to the base plate 63. When the base plate 63 rotates, it can also be used as a rotating platform.

[0044] The top of the side plate 62 is connected to the top plate 61, and the top of the side plate 62 is connected to the bottom plate 63. A slot 64 is provided in the middle of the upper surface of the top plate 61. The top plate 61, the bottom plate 63, and the side plate 62 together form a semi-enclosed shell. The middle and upper parts of the slider 72 and the rocker arm 75 are both arranged in the shell. The tip of the clamp arm 71 extends out of the slot 64 and is slidably connected to the inner wall of the slot 64.

[0045] The side panel 62 and the bottom panel 63 are L-shaped. The side panel 62 is mainly used to connect the lamp 91 and the camera 92. The width of the camera 92 is greater than the width of the lamp 91. In order to ensure the gravity balance and aesthetics on both sides of the bottom bar 1, the width of the side panel 62 is adapted to the width of the camera 92. There is no need to fix objects on the other two sides, so the side panel 62 is not set, which saves materials, reduces weight, and can also reduce the volume of the head of the entire device, making it easier to extend into a smaller space.

[0046] The width of the bottom plate 63 is greater than that of the support ring 34 . The bottom plate 63 is placed on the support ring 34 . The support ring 34 is located directly below the middle of the bottom plate 63 . The angle between the rocker arm 75 and the vertical plane during movement is 5°-75°.

[0047] When the included angle between the rocker rod 75 and the vertical plane is 5°, the two sliders 72 are in contact, and at this time, the included angle between the rocker rod 75 and the vertical plane is the smallest.

[0048] When the angle between the rocker bar 75 and the vertical plane is 75°, the two sliders 72 are farthest apart. When not under maintenance, the two clamping arms 71 are mostly in this state.

[0049] The two sliders 72 are symmetrically distributed along the longitudinal axis of the support rod 65. The bottom of each slider 72 is connected to the top of the two first sleeves 73. The two first sleeves 73 are distributed at the edges on both sides of the bottom of the slider 72. The first sleeve 73 is rotatably connected to the first rotating rod 74. A plurality of connecting arms 78 are connected to the side of the cylinder 77. The plurality of connecting arms 78 are equidistantly distributed in the circumferential direction of the cylinder 77. The end of each connecting arm 78 away from the axis of the cylinder 77 is connected to the side of a second sleeve 79.

[0050] When in use, the telescopic rod 31 is stretched, and the head of the device (the part where the clamp arm 71 is located) is extended into the inspection place, the light 91 and the camera 92 are started, and the approximate location of the problem is determined based on the picture transmitted by the camera 92, and the stepper motor 42 is started. The rotating part of the stepper motor 42 sequentially drives the hydraulic cylinder 5, the bottom plate 63, the side plate 62, the top plate 61, the light 91, the camera 92, the clamp arm 71, the slider 72, etc. to rotate in a preset direction (which can be set by oneself), and the rotation speed can be adjusted by oneself. The overall rotation speed is slow, which can facilitate the camera 92 to shoot and transmit a clear picture, and it can also be convenient to stop the rotation, carefully observe the suspicious place, facilitate the determination of the target, and reduce the overall rotation speed to reduce the damage caused by the collision during the rotation process. During the rotation process, the bottom plate 63 is placed on the support ring 34, and the support ring 34 is used as the main support member to support the overall component where the clamp arm 71 is located, reduce the pressure on the piston rod, and improve the overall stability of the device. In a narrow environment, the increased field of view of the rotating camera 92 is sufficient to fully understand the maintenance environment. The exact position of the maintenance component is determined by the image transmitted back by the rotating camera 92. The stepper motor 42 is turned off and the head of the device is manually moved to the clamping position of the maintenance component so that the maintenance component is located between the two clamping arms 71.

[0051] Start the hydraulic cylinder 5, and the telescopic end of the hydraulic cylinder 5 moves downward with the cylinder body 77, the connecting wall, the second sleeve 79, and the second rotating rod 76 in sequence. Since the slider 72 can only slide along the axial direction of the support rod 65, and the length of the rocker arm 75 is fixed, the first rotating rod 74 and the second rotating rod 76 both rotate, and the slider 72 moves toward the direction close to the central axis of the support rod 65. The two sliders 72 approach each other, and the two clamping arms 71 tighten, so that the clamping arms 71 can clamp the object to be inspected.

[0052] The stepper motor 42 is started again. The stepper motor 42 rotates at the same angle each time, and the angle of each rotation is 25°-95°. The stepper motor 42 drives the clamp arm 71 to rotate. The angle of each rotation is small. Each rotation tightens the loose parts by one point. The stepper motor 42 stops rotating after rotating once. If the object to be inspected is still loose, the hydraulic cylinder 5 is turned off and started again to complete the process of loosening and then clamping the clamp arm 71 and the object to be inspected. The stepper motor 42 is started and rotated again until the object to be inspected is completely tightened.

[0053] The stepper motor 42 can drive the rotation of the camera 92 to complete the shooting of the maintenance environment and the maintenance object, expand the visualization range, and avoid blind spots in the shooting. It can also control the rotation of the clamp arm 71 by regular rotation at a small angle, so that the clamp arm 71 assists in rotating and tightening the maintenance object. One power source assists multiple tasks, saves power, reduces costs, reduces the overall weight of the device, and supports the miniaturization development and mass production of the device.

[0054] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
