DETAILED DESCRIPTION

[0026] The following will be described in detail with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 3 The application will be further described in detail.

[0027] A temporary electric power transmission pole, referring to Figure 1 and Figure 2 , comprises a base 1, a wire supporting frame 2, a lifting mechanism 3, a wire pressing plate 4, a rotating mechanism 5 and a fixing mechanism 6. The lifting mechanism 3 is installed on the base 1, the wire supporting frame 2 is installed on the lifting mechanism 3, and the wire supporting frame 2 is driven by the lifting mechanism 3 to move along the vertical direction. A limiting groove 21 is formed on the top surface of the wire supporting frame 2, and the limiting groove 21 is used to bear the electric wire. The wire pressing plate 4 has a fixed end and a rotating end, the rotating end of the wire pressing plate 4 is rotationally connected to the wire supporting frame 2, and the fixing mechanism 6 is used to fix the fixed end of the wire pressing plate 4 and the wire supporting frame 2. When the fixed end of the wire pressing plate 4 and the wire supporting frame 2 are in close contact with each other, the electric wire is limited in the limiting groove 21, and the separation of the electric wire from the wire supporting frame 2 is reduced. The rotating mechanism 5 is used to drive the wire pressing plate 4 to rotate.

[0028] When temporary repair is carried out, the wire holder 2 is driven upward by the lifting mechanism 3, and the wire falls into the limiting groove 21. At this time, the wire holder 2 is driven upward to the specified height, so that the maintenance personnel can carry out construction. When the wire falls into the limiting groove 21, the pressing plate 4 is driven to abut against the wire holder 2 by the rotating mechanism 5. At this time, the fixing mechanism 6 operates to fix the pressing plate 4 and the wire holder 2 to each other, so that the wire is limited in the limiting groove 21, and the situation that the wire is separated from the limiting groove 21 is reduced.

[0029] Further, the wire holder 2 is fixedly connected with the baffle 7, which is located at the rotating end of the pressing plate 4. By arranging the baffle 7, the rotating angle of the pressing plate 4 is limited, so that the situation that the pressing plate 4 is excessively rotated is avoided. That is, when the wire needs to be placed in the limiting groove 21, the pressing plate 4 is first rotated to abut against the baffle 7.

[0030] Further, the rotating mechanism 5 comprises a first winch 51, a first pull rope 52 and a first pulley 53. The first winch 51 is fixedly installed on the base 1, and the first pulley 53 is fixedly installed at the top end of the baffle 7. The first pull rope 52 is lapped on the first pulley 53, and one end of the first pull rope 52 is fixed on the first winch 51, and the other end is fixed on the fixed end of the pressing plate 4. By rotating the first winch 51, the first pull rope 52 is wound, so that the first pull rope 52 drives the pressing plate 4 to rotate, so as to open the limiting groove 21, and the wire can fall into the limiting groove 21. When the wire is placed in the limiting groove 21, the first pull rope 52 is used to unwind, so that the pressing plate 4 rotates to the direction of the wire holder 2, and finally abuts against the wire holder 2. In the embodiment, in order to ensure that the pressing plate 4 can normally rotate to the direction of the wire holder 2 during unwinding of the first winch 51, the rotating angle of the pressing plate 4 is limited to 0-80°.

[0031] Specifically, the fixed end of the pressing plate 4 is fixedly connected with the counterweight 8. When the pressing plate 4 rotates to abut against the baffle 7, the pressing plate 4 is limited to rotate by the baffle 7. At this time, the angle between the pressing plate 4 and the horizontal plane is less than 80°, so that the pressing plate 4 can rotate to the direction of the wire holder 2 when the first winch 51 is unwound. Moreover, due to the arrangement of the counterweight 8, the fixed end of the pressing plate 4 is heavier, so that the rotation of the pressing plate 4 is more convenient.

[0032] Referring to Figure 2 Further, the fixing mechanism 6 comprises a fixed block 61, a sliding block 62 and a driving assembly 63. The fixed block 61 is slidably arranged on the wire holder 2. In the embodiment, a sliding groove 22 is formed in the inner bottom wall of the limiting groove 21. One end of the sliding block 62 is inserted into the sliding groove 22 and can slide in the sliding groove 22. The fixed block 61 is fixedly connected to the other end of the sliding block 62 and forms an L-shaped structure together with the sliding block 62.

[0033] The pressure line plate 4 is provided with an avoiding groove 41 on the side close to the line supporting frame 2. When the pressure line plate 4 is overlapped with the line supporting frame 2, the avoiding groove 41 is in position corresponding to the sliding groove 22 and the fixed block 61 is inserted into the avoiding groove 41. At this time, the sliding block 62 slides in the sliding groove 22 and drives the fixed block 61 to slide in the avoiding groove 41. The inner side wall of the avoiding groove 41 away from the fixed end of the pressure line plate 4 is provided with a fixed groove 42. The fixed block 61 can slide from the avoiding groove 41 and be inserted into the fixed groove 42, so as to realize the mutual fixation between the pressure line plate 4 and the line supporting frame 2.

[0034] In the specific use process, after the electric wire is put into the limiting groove 21, the first winch 51 is used to release the wire, so as to rotate the pressure line plate 4 to overlap with the line supporting frame 2. At this time, the fixed block 61 is inserted into the avoiding groove 41. The sliding block 62 is driven to slide by the driving assembly 63, so as to insert the fixed block 61 into the fixed groove 42, thereby realizing the mutual fixation between the pressure line plate 4 and the line supporting frame 2 and reducing the situation that the electric wire is separated from the limiting groove 21.

[0035] Further, the fixed block 61 is provided with an inclined surface 611. When the pressure line plate 4 rotates, the avoiding groove 41 opening can abut against the inclined surface 611. That is, when the pressure line plate 4 rotates to the direction close to the line supporting frame 2, it first abuts against the inclined surface 611 of the fixed block 61. At this time, the fixed block 61 slides under the guidance of the inclined surface 611 and is finally inserted into the avoiding groove 41. After the fixed block 61 is inserted into the avoiding groove 41, the sliding block 62 is driven to slide by the driving assembly 63, so as to insert the fixed block 61 into the fixed groove 42, thereby realizing the automatic fixation between the pressure line plate 4 and the line supporting frame 2.

[0036] Referring to Figure 1 and Figure 2 , specifically, the driving assembly 63 includes a second pull rope 631, a second winch 632 and an elastic member 633. The elastic member 633 is arranged in the sliding groove 22 and acts on the sliding block 62 at one end and on the inner wall of the sliding groove 22 at the other end. In this embodiment, the elastic member 633 is a spring and is fixed to the sliding block 62 at one end and to the inner wall of the sliding groove 22 at the other end. When the pressure line plate 4 abuts against the inclined surface 611, the fixed block 61 slides under the guidance of the inclined surface 611 due to the action of the counterweight 8 and its own gravity, so as to compress the elastic member 633. After the fixed block 61 is inserted into the avoiding groove 41, the elastic member 633 restores, thereby driving the sliding block 62 to reset and inserting the fixed block 61 into the fixed groove 42, so as to fix the pressure line plate 4.

[0037] The second winch 632 is fixed on the base 1, one end of the second pull rope 631 is fixed on the sliding block 62, and the other end is fixed on the second winch 632. When it is needed to release the fixing of the pressing wire plate 4, the second winch 632 is rotated at this time, so as to drive the sliding block 62 to slide away from the fixed groove 42, so that the fixed block 61 and the fixed groove 42 are separated from each other. At this time, the first winch 51 is rotated, so as to drive the pressing wire plate 4 to rotate, and the limiting groove 21 is opened.

[0038] Further, the driving assembly 63 comprises a second pulley 634, the second pulley 634 is fixed on the wire supporting frame 2, and the second pull rope 631 is lapped on the second pulley 634. By arranging the second pulley 634, the friction between the second pull rope 631 and the wire supporting frame 2 is reduced, so as to reduce the abrasion of the second pull rope 631.

[0039] Referring to Figure 1 and Figure 3 Further, the lifting mechanism 3 comprises a lifting rod 31, a screw rod 32, an outer sleeve 33 and a driving piece 34. The outer sleeve 33 is fixed on the base 1, the lifting rod 31 is slidingly arranged in the outer sleeve 33, the cross section of the lifting rod 31 is rectangular, the outer sleeve 33 is matched with the shape of the lifting rod 31. Since the cross section of the lifting rod 31 is rectangular, the mutual rotation between the lifting rod 31 and the outer sleeve 33 is limited, so as to ensure that the lifting rod 31 can only slide in the vertical direction. The screw rod 32 is rotationally arranged on the base 1, the screw rod 32 penetrates through the lifting rod 31 and is screwed with the lifting rod 31, and the output end of the driving piece 34 is fixedly connected with the screw rod 32. The screw rod 32 is driven to rotate by the driving piece 34, so as to drive the lifting rod 31 to move up and down. The upper end of the lifting rod 31 is fixedly connected with the wire supporting frame 2. The wire supporting frame 2 is driven to move by the movement of the lifting rod 31, so as to transport the electric wire to a specified height.

The same parts are indicated by the same reference numerals. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
