Description

Technical Field

[0001] The present invention relates to electric power construction technology, in particular to a wiring auxiliary device used for power grid construction. Background Art

[0002] The laying of transmission lines requires the construction of transmission towers or transmission poles first, and the placement of transmission lines on the crossarms of the transmission towers or transmission poles. Construction workers then need to climb to the top of the transmission towers or transmission poles to install insulators. After the insulators are installed, the transmission lines are lifted into the top grooves of the insulators to complete the line construction.

[0003] At present, the construction of transmission line stringing is too dependent on manpower. In the process of lifting the transmission line to the groove at the top of the insulator, the construction workers need to support the heavy transmission line with their shoulders and lift the transmission line to the same height as the top of the insulator. Then, they adjust the position of the transmission line by moving their bodies and install it in the groove at the top of the insulator. Since this process is carried out on the top of the transmission tower or transmission pole, and the construction workers mainly use foot buckles or cross arms as footholds, a slight carelessness may cause a fall accident, which poses a great threat to personnel safety. In addition, during the construction process, if a high-voltage transmission line with a thicker wire diameter is encountered during construction, the construction workers will need to expend more physical strength to lift the transmission line, which makes them consume more physical strength. This not only greatly increases the work risk of the construction workers, but also makes the stringing construction efficiency relatively low, which is not conducive to the progress of the power grid construction stringing work.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] See also Figure 1-Figure 5A wiring auxiliary device for power grid construction includes a vertical plate 1, a support base 2 is fixedly mounted on one side of the vertical plate 1, a rotating base 21 is provided on the top of the support base 2, a lifting arm 22 is rotatably connected to the rotating base 21, and a bearing groove 23 is formed at the end of the lifting arm 22;

[0035] A cavity is provided inside the support base 2, and a winding wheel 3 is rotatably connected to the inner wall of the cavity. A steel wire rope 31 is wound on the outside of the winding wheel 3. A guide groove 32 is provided inside the vertical plate 1 in the vertical direction. The end of the steel wire rope 31 away from the winding wheel 3 enters from the bottom of the guide groove 32 and passes through the top thereof and is fixedly connected to the end of the lifting arm 22 away from the rotating base 21. A large gear 33 is coaxially fixedly connected to the outside of the winding wheel 3, and a small gear 34 is rotatably connected to the inner wall of the cavity. A rotating wheel 35 coaxially arranged with the small gear 34 is rotatably connected to the surface of the support base 2, and a telescopic tube 36 is installed on the outside of the rotating wheel 35.

[0036] Two sets of locking hoop units are installed on the other side of the vertical plate 1, which are distributed up and down. The locking hoop units are used to connect and fix the vertical plate 1 to the utility pole;

[0037] An adjustment unit is installed between the rotating base 21 and the supporting base 2 , and the adjustment unit is used to adjust the lifting position of the jacking arm 22 .

[0038] It should be added that the bearing groove 23 is arranged in an arc shape, and the shape of the bearing groove 23 is three-quarter circle, so that the bearing groove 23 can well support the transmission line during the upward rotation of the jacking arm 22.

[0039] It should be further explained that the lifting arm 22 is initially tilted, and the end of the lifting arm 22 away from the vertical plate 1 is tilted upward. The top end of the guide groove 32 is higher than the connection point between the wire rope 31 and the lifting arm 22. The upper and lower ends of the guide groove 32 are both provided with rounded corners, so that the resistance of the wire rope 31 to the lifting arm 22 when it initially pulls upward is small.

[0040] In this embodiment, the large gear 33 is meshed with the small gear 34 , and the gear ratio between the large gear 33 and the small gear 34 is 5:1.

[0041] It should be noted that the large gear 33 is driven to rotate by the small gear 34 to provide driving force for the upward rotation of the jacking arm 22, so that the power output required by the operator is smaller. At the same time, with the cooperation of the telescopic tube 36, the length of the power arm can be increased when the operator applies the rotational force, thereby greatly reducing the driving force required by the operator, making the upward rotation of the jacking arm 22 easier.

[0042] In this embodiment, the locking hoop unit includes a mounting base 4 fixedly mounted on the other side of the vertical plate 1, and two groups of arc-shaped hoop plates 41 are symmetrically rotatably connected on both sides of the mounting base 4. The end of the arc-shaped hoop plate 41 away from the vertical plate 1 is fixedly connected to a fixing plate 42, and a bolt groove 43 is provided on the surface of the fixing plate 42. The two fixing plates 42 are connected with a fastening nut 45 by a fastening bolt 44. The surface of the mounting base 4 is provided with an arc-shaped groove 46 that is compatible with the two groups of arc-shaped hoop plates 41, and the inner wall of the arc-shaped groove 46 and the inner surface of the arc-shaped hoop plate 41 are both roughened.

[0043] In this embodiment, the adjusting unit includes a rotating base 5 rotatably connected to the top of the support base 2, and the rotating base 21 is rotatably connected to the top of the rotating base 5. A cylindrical groove 51 is provided inside the rotating base 21, and a baffle 52 is slidably connected to the inner side surface of the cylindrical groove 51. The top of the baffle 52 is fixedly connected to a lifting rod 53, and the top of the lifting rod 53 passes through the top of the rotating base 21. A compression spring 54 is fixedly connected between the top of the baffle 52 and the top of the inner wall of the cylindrical groove 51, and the bottom of the baffle 52 is fixedly connected to a positioning rod 55. The surface of the rotating base 5 is provided with four positioning grooves 56 equidistantly distributed in a circular shape. The position and specifications of the positioning grooves 56 correspond to the positioning rod 55, and the positioning rod 55 can be inserted into the positioning groove 56.

[0044] During the jacking process of the transmission line, the operator climbs to the top of the utility pole and fits the vertical plate 1 to the appropriate position on the utility pole so that the vertical plate 1 faces the direction of the transmission line. Then, the arc-shaped hoop plates 41 on both sides are rotated and connected and fixed by tightening bolts 44 and fastening nuts 45 to complete the installation of the vertical plate 1.

[0045] The operator pulls up the lifting rod 53, and the lifting rod 53 moves to drive the blocking piece 52 and the positioning rod 55 to move upward, so that the positioning rod 55 moves out of the positioning groove 56. At this time, the rotating seat 21 and the rotating base 5 can rotate relative to each other. Then the operator rotates the rotating seat 21, and the rotating seat 21 rotates and drives the jacking arm 22 to rotate, so that the jacking arm 22 rotates 90 degrees and is perpendicular to the direction of the transmission line. After that, the lifting rod 53 is released, so that the positioning rod 55 can be reinserted into the positioning groove 56, so that the jacking arm 22 has better stability during subsequent work. Then, the transmission line hanging down on one side of the cross arm is engaged in the bearing groove 23.

[0046] After the transmission line is connected to the jacking arm 22, the operator pulls the telescopic tube 36 outward to stretch it to its longest value. Then, the operator applies a driving force to the end of the telescopic tube 36 away from the rotating wheel 35, causing the rotating wheel 35 to rotate. The rotation of the rotating wheel 35 drives the small gear 34 to rotate. The rotation of the small gear 34 drives the large gear 33 to rotate. The rotation of the large gear 33 drives the reeling wheel 3 to rotate. During the rotation of the reeling wheel 3, the wire rope 31 is reeled in. Under the guidance of the guide groove 32, when one end of the wire rope 31 is reeled in, its other end can pull the jacking arm 22 to rotate upward. When the lifting arm 22 rotates upward, it can drive the transmission line to move upward. When the transmission line is lifted to a suitable height, the operator stops rotating the telescopic tube 36 and pulls the lifting rod 53 upward so that the rotating seat 21 can rotate relative to the rotating base 5. At this time, the operator can adjust the front and rear position of the transmission line by slightly rotating the lifting arm 22. In this process, the tension of the wire rope 31 can be adapted by slightly rotating the wheel 35, so that the transmission line can fall more smoothly into the groove on the top of the insulator.

[0047] Example 2:

[0048] See also Figure 6-Figure 8 This embodiment provides a technical solution based on the above embodiment: the outside of the support seat 2 is rotatably connected to a ratchet 6 coaxially fixedly connected to the large gear 33, and a circular cover 61 is fixedly installed on the outside of the support seat 2. The inner wall of the circular cover 61 is rotatably connected to a pawl 62 adapted to the ratchet 6, and an extrusion spring 63 is fixedly connected between the surface of the pawl 62 and the inner wall of the circular cover 61. The pawl 62 can limit the ratchet 6 from rotating in one direction.

[0049] In this embodiment, a circular groove 64 is provided inside the rotating wheel 35, and the external rotation of the support seat 2 is connected to a limiting wheel 65 located inside the circular groove 64. The limiting wheel 65 is coaxially fixedly connected to the pinion 34, and a plurality of matching grooves 66 are provided in a circular ring shape on the limiting wheel 65. The inner wall of the rotating wheel 35 is provided with multiple groups of straight grooves 67, and the inner wall of the straight groove 67 is fixedly connected to a connecting spring 68, and the end of the connecting spring 68 is fixedly connected to a matching block 69.

[0050] In this embodiment, a first guide bevel 610 is provided on one side of the inner wall of the mating groove 66, and a first driving straight surface 611 is provided on the other side of the inner wall of the mating groove 66. A second guide bevel 612 and a second driving straight surface 613 corresponding to the first guide bevel 610 and the first driving straight surface 611 respectively are provided on the mating block 69.

[0051] It should be added that the direction in which the pawl 62 limits the unidirectional rotation of the ratchet 6 is consistent with the direction in which the second driving surface 613 pushes the first driving surface 611 to rotate, and the rotatable direction of the ratchet 6 is consistent with the rotation direction of the winding wheel 3 when winding the wire rope 31.

[0052] When outputting driving force to the jacking arm 22, the operator can rotate the telescopic tube 36 according to his actual position so that it can be rotated to an angle that is convenient for the operator to exert force. In the process of driving the jacking arm 22 to rotate, after the operator rotates the telescopic tube 36 to drive the small gear 34 to rotate a certain angle, the operator can rotate the telescopic tube 36 in the opposite direction to make the rotating wheel 35 rotate in the opposite direction. In this process, the reverse rotation of the large gear 33 is restricted by the cooperation between the ratchet 6 and the pawl 62, so that the jacking arm 22 cannot automatically return to the opposite direction after being jacked up.

[0053] During the normal rotation of the rotating wheel 35, its rotation will drive the second driving straight surface 613 on the matching block 69 to abut against the first driving straight surface 611 in the matching groove 66, and apply thrust, so that the rotation of the rotating wheel 35 can drive the limiting wheel 65 to rotate synchronously, and the rotation of the limiting wheel 65 can drive the pinion 34 to rotate, thereby normally driving the lifting arm 22 to rotate upward. When the rotating wheel 35 rotates in the reverse direction, the ratchet 6 and the pawl 62 cooperate to limit the reverse rotation of the pinion 34, that is, to limit the reverse rotation of the limiting wheel 65, so that the rotating wheel 35 When the reverse rotation of 35 drives the second guide bevel 612 on the matching block 69 to abut against the first guide bevel 610 on the matching groove 66 and apply a thrust, under the guiding action of the second guide bevel 612 and the first guide bevel 610, the matching block 69 will move toward the inside of the straight groove 67 and compress the connecting spring 68, so that the matching block 69 and the limiting wheel 65 rotate relative to each other, and the position of the telescopic tube 36 can be adjusted in the reverse direction, so that the rotation angle of the telescopic tube 36 is always within the range that the operator can easily apply force, thereby facilitating the operator to lift the transmission line upward.

[0054] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
