Description

Technical Field

[0001] The invention relates to the technical field of live working, and in particular to a pole-mounted switch shielding cover installation and operation device. Background Art

[0002] The pole-mounted switch shielding cover is a protective device in the field of power equipment technology. The main function of the pole-mounted switch shielding cover is to shield the exposed part of the switch to prevent operators from accidentally touching it during live operations, thereby protecting the safety of operators. The shielding cover can also prevent rain, dust and other substances from entering the inside of the switch, ensuring the normal operation of the equipment and extending its service life.

[0003] In the current installation practice of pole-mounted switch shielding covers, workers are mainly lifted to the high-altitude working position by insulated boom trucks, and workers need to wear a full set of insulating equipment to operate. However, this method faces many challenges: first, complex terrain often limits the accessibility of insulated boom trucks, making it impossible to effectively install in some areas; second, high operating costs, including the deployment of a large number of workers and the configuration of insulated boom trucks, increase the project burden; third, workers are in close contact with live parts, which poses extremely high safety risks and may cause phase-to-ground or phase-to-phase short circuit accidents; finally, the cumbersome steps and complicated procedures in the installation process lead to low work efficiency and long time consumption.

[0038] When the present invention is used, a worker wears insulating gloves and holds the insulating rod 1, and starts the regulating motor 3 to rotate the second bevel gear 22. Figure 4 When the state rotates clockwise, the rotating rod 67 rotates clockwise around the axis of the second bevel gear 22. During the clockwise rotation of the rotating rod 67, the rotating rod 67 will contact the inclined surface of the triangular block 23, and as the rotating rod 67 continues to rotate clockwise, the triangular block 23 moves downward, the telescopic rod 24 retracts, and the second spring 25 is compressed, and finally moves from the side of the triangular block 23 with the inclined surface to the other side of the triangular block 23. The triangular block 23 is reset due to the elastic force generated by the compression of the second spring 25, and so on. During this process, the moving plate 26 will not move. When the second bevel gear 22 rotates clockwise, due to the second The bevel gear 22 is meshed and connected with the first bevel gear 21. A one-way bearing is provided between the first bevel gear 21 and the first reciprocating screw 40. The first bevel gear 21 is fixed to the outer ring of the one-way bearing, and the first reciprocating screw 40 is fixed to the inner ring of the one-way bearing. Thus, when the first bevel gear 21 rotates in one direction, the inner and outer rings of the one-way bearing are locked, so that the first reciprocating screw 40 rotates. The first threaded block 65 can reciprocate up and down. By providing the first auxiliary rod 41, the "U"-shaped frame 9 and other components on the "U"-shaped frame 9 can move up and down as a whole, so that the height of the installation operation can be adjusted.

[0039] When the second bevel gear 22 is moved along the adjacent Figure 4When the first bevel gear 21 rotates in the other direction, its rotating rod 67 rotates counterclockwise around the axis of the second bevel gear 22. During the counterclockwise rotation of the rotating rod 67, the rotating rod 67 contacts the plane of the triangular block 23, and as the rotating rod 67 continues to rotate counterclockwise, the triangular block 23, the telescopic rod 24, the movable plate 26, the square rod 33 and the blowing plug 42 can move to the right as a whole for a distance and finally separate from the triangular block 23 and no longer contact each other. When the rotating rod 67 is separated from the triangular block 23 and no longer in contact, the third spring 34 is provided to enable the triangular block 23, the telescopic rod 24, the movable plate 26, the square rod 33 and the blowing plug 42 to move to the left as a whole and return to the initial position, and so on. When the blowing plug 42 moves to the right, the air in the blower cylinder 31 can be squeezed into the blower box 4 through the second connecting pipe 32 and sprayed from the nozzle on the blower box 4 to the insulating rod 1, so that the insulating rod 1 can be partially blown, thereby reducing the possibility of condensation at the gripping position, thereby strengthening the gripping force and avoiding the hand from slipping. When the blowing plug 42 moves to the left, the external air is filtered and sucked into the blower cylinder 31 (in this process, the movable plate 26 cannot contact the round block 37);

[0040] When the limiting block 5 makes the adjusting cylinder 63 and the round block 37 approach the moving plate 26, the first spring 6 is compressed, and the movement of the adjusting cylinder 63 drives the clamping rod 43 to move toward the direction of approaching the first right-angle trapezoidal block 28, so that the clamping rod 43 and the inclined surface of the first right-angle trapezoidal block 28 contact each other, and as the clamping rod 43 continues to move, the displacement block 27, the two fixed blocks 30, the two first right-angle trapezoidal blocks 28 and the second right-angle trapezoidal block 44 are moved along the adjacent Fig.10 When the first adjusting cylinder 63 and the first round block 37 move backward synchronously, the fifth spring 45 is compressed. When the first clamping rod 43 moves to between the first right-angle trapezoidal block 28 and the displacement block 27, the elastic force generated by the compression of the fifth spring 45 resets the displacement block 27, the two fixed blocks 30, the two first right-angle trapezoidal blocks 28 and the second right-angle trapezoidal block 44, so that the first clamping rod 43 is stuck, that is, the first adjusting cylinder 63 and the first round block 37 move a distance toward the direction close to the moving plate 26. At this time, as the second bevel gear 22 moves along the adjacent Figure 4In the state, the moving plate 26 rotates counterclockwise. During the process of the moving plate 26 continuing to reciprocate, the moving plate 26 will contact with one of the round blocks 37 and push one of the round blocks 37 to move. Through the fourth spring 39, the one of the adjusting plugs 64 can reciprocate for a distance, so that the oil in the one of the adjusting cylinders 63 can be squeezed into the rotating box 12 or the inner cavity 55 through the first connecting tube 7, and then the oil squeezed into the rotating box 12 or the inner cavity 55 is sucked into the one of the adjusting cylinders 63 through the first connecting tube 7. In this way, the rotating plug 51 or the rectangular clamp plug 66 can be reciprocated. The rectangular push rod 50 is provided to enable the first driving rod 52 or the second driving rod 60 to reciprocate. Since the rectangular push rod 50 and the rectangular clamp 66 are both rectangular, the first driving rod 52 and the second driving rod 60 will not rotate during the movement. The first protrusion 54 is slidably connected to the first spiral groove 53, and the second protrusion 62 is slidably connected in the second spiral groove 61. Therefore, during the reciprocating movement of the first driving rod 52 or the second driving rod 60, the first protrusion 54 slides in the first spiral groove 53 or the second protrusion 62 slides in the second spiral groove 61. The first sleeve 49 or the second sleeve 56 can be reciprocated clockwise and counterclockwise for multiple turns. When the first sleeve 49 rotates clockwise and counterclockwise for multiple turns, a one-way bearing is provided between the first sleeve 49 and the second reciprocating screw 47. When the first sleeve 49 rotates in one direction, the inner and outer rings of the one-way bearing are locked, and the second reciprocating screw 47 rotates accordingly, thereby causing the second threaded block 46 and the single-sided rack 13 to reciprocate left and right. By providing the first gear 14, the first rotating shaft 15 and the rotating frame 10 can be rotated accordingly, so that the operating angle is always installed. The degree of adjustment is that when the first sleeve 49 rotates in the other direction, the inner and outer rings of the one-way bearing thereof idle, and the second reciprocating screw 47 cannot rotate, that is, the single-sided rack 13 does not move. Similarly, when the second sleeve 56 reciprocates clockwise and counterclockwise for multiple circles, the second sleeve 56 rotates in one direction, and the third reciprocating screw 57 rotates accordingly, and the double-sided rack 16 and the third threaded block 58 reciprocate. By setting the second gear 18, the second rotating shaft 17 and the connecting rod 19, the clamping plate 20 can be opened and closed to clamp the shielding cover to assist the installation operation of the shielding cover.

[0041] When the other adjusting cylinder 63 and the other round block 37 are brought close to the moving plate 26, the other clamping rod 43 moves in the direction close to the first right-angle trapezoidal block 28, so that the other clamping rod 43 and the inclined surface of the first right-angle trapezoidal block 28 contact each other, and as the other clamping rod 43 continues to move, the displacement block 27, the two fixed blocks 30, the two first right-angle trapezoidal blocks 28 and the second right-angle trapezoidal block 44 are moved along the adjacent Fig.10The state moves backward synchronously, the fifth spring 45 is compressed, and when the other clamping rod 43 moves to the point where it just does not contact the inclined surface of the first right-angled trapezoidal block 28, one of the clamped clamping rods 43 will be reset under the action of the first spring 6, and the other clamping rod 43, under the elastic force generated by the compression of the fifth spring 45, resets and clamps the displacement block 27, the two fixed blocks 30, the two first right-angled trapezoidal blocks 28 and the second right-angled trapezoidal block 44, so that the oil body is squeezed into the rotating box 12 or the inner cavity 55. By moving the rectangular block 29 in the direction of the movable plate 26, the clamping rod 43 on the rectangular block 29 can be moved in the direction close to the second right-angled trapezoidal block 44, so that the displacement block 27, the two fixed blocks 30, the two first right-angled trapezoidal blocks 28 and the second right-angled trapezoidal block 44 can be moved along the attached Fig.10 The state moves backward synchronously, thereby realizing the reset of any one of the clamping rods 43 on the two adjusting cylinders 63, but the clamping rod 43 on the rectangular block 29 will not be stuck, thus realizing the reset of the two adjusting cylinders 63.
