[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1-4 As shown, the utility model proposes an electric power construction guide frame, including a base plate 2, a pedestal 3, an outer cylinder 5 and a frame 8. The base 3 is rotatably arranged on the base plate 2, and an axis head 4 is rotatably provided on the base 3. The axis head 4 is positioned on the base 3 through a positioning assembly. The outer cylinder 5 is provided on the axis head 4, and the frame 8 is lifted and lowered on the outer cylinder 5 through a lifting assembly. A roller 7 is rotatably provided on the frame 8, and a shaft rod 12 is provided at the upper end of the inner wall of the frame 8. Two rollers 7 are symmetrically rotatably mounted on the shaft rod 12.

[0027] Based on Example 1:

[0028] During the use of the electric power construction guide frame of the utility model, the electric power construction guide frame can be moved to a specified position by the brake wheel 1, and the line-laying angle can be adjusted. At this time, the shaft head 4 is rotated so that the roller 7 is located above the wellhead of the cable well. When the cable is released, the cable passes through the roller 7 and enters the cable well vertically, which can avoid excessive friction between the cable and the wellhead and the well wall during the line-laying process.

[0029] Furthermore, the pay-off height can be adjusted. When necessary, the lifting assembly drives the roller 7 to move up and down on the outer cylinder 5, thereby changing the height of the roller 7 and thus changing the pay-off height of the cable. When the device is not in use, the outer cylinder 5 is deflected so that the outer cylinder 5 is flush with the bottom plate 2, thereby facilitating the movement of the device.

[0030] Example 2

[0031] like Figures 1-4 As shown, the utility model proposes an electric power construction guide frame, compared with the first embodiment, this embodiment also includes: the positioning component is composed of a pin rod 13 and a positioning groove 14, the pin rod 13 is movably inserted into the base 3, and each positioning groove 14 is equidistantly arranged at the end of the shaft head 4, and the bottom end of the pin rod 13 is inserted into the positioning groove 14. Through the design of the positioning component, in the process of rotating the shaft head 4 to make the outer cylinder 5 drive the roller 7 to deflect, when the deflection angle of the roller 7 is determined, the pin rod 13 is inserted into the corresponding positioning groove 14 through the base 3, so that the angle of the outer cylinder 5 can be fixed.

[0032] The lifting assembly consists of a threaded block 6, a handle 9, a screw 15 and a slider 16. The slider 16 is slidably inserted in the outer tube 5, and the screw 15 is fixed on the slider 16. The sliding contact surface between the slider 16 and the outer tube 5 is square in design. The threaded block 6 is rotatably arranged on the upper surface of the outer tube 5.

The handle 9 is arranged on the outer wall of the threaded block 6, and each handle 9 is distributed in a circular array on the outer wall of the threaded block 6. During use, the personnel rotates the threaded block 6 through the handle 9. Through the meshing action between the threaded block 6 and the screw 15, and the screw 15 is limited and does not deflect, under the principle of the screw, the screw 15 can be driven to perform a lifting action, thereby changing the height of the roller 7.

[0033] Two positioning seats 11 are symmetrically provided on the bottom plate 2, and a counterweight block 10 is provided on each of the two positioning seats 11. The design of the counterweight block 10 ensures that the force on the bottom plate 2 is balanced when the device adjusts the line-laying angle.
