[0012] Figure 2 It is a structural schematic diagram of the GNSS equipment positioning device for main cable deviation monitoring in Example 2. DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] Example 1

[0015] The GNSS equipment positioning device for main cable deviation monitoring comprises a lower buckle plate 1, an upper buckle plate 2, a left positioning screw rod 3, a right positioning screw rod 4, a mounting rod 5 and a GNSS device 6.

[0016] The lower gusset plate 1 is a vertical "L"-shaped plate. At the angle shown in the figure, its left side is vertical and its right side is horizontal. A left positioning screw 3 is vertically fixedly connected to the top of the left side.

[0017] A through hole is vertically provided on the right side of the lower buckle plate 1, near the right end; a scale is drawn on the upper side of the right side, in the area located on the left side and before the through hole, which is recorded as the first scale; a level bubble is provided on the lower side of the right side, near the through hole.

[0018] The upper gusset plate 2 is a long strip plate, which is horizontally arranged at the angle shown in the figure.

[0019] The upper buckle plate 2 is provided with a through hole vertically at a position near both ends; a scale is drawn on the lower side, in the area between the two through holes, marked as the second scale, and the first and second scales are aligned vertically; a slide rail 21 is provided at the middle position on the upper side at an angle parallel to the upper buckle plate 2; a level bubble is provided on the upper side near the through hole.

[0020] The upper end of the left positioning screw 3 passes through the through hole at the left end of the upper gusset plate 2; the upper end of the right positioning screw 4 passes through the through hole at the right end of the upper gusset plate 2, and the lower end passes through the through hole at the right end of the lower gusset plate 1. Nuts are provided at the upper end of the left positioning screw 3 and at both ends of the right positioning screw 4.

[0021] The slide rail 21 has a slider that can slide left and right, and two threaded holes are drilled on the slider at an angle perpendicular to the upper gusset plate 2, and limit screws are screwed into the threaded holes. When the slider needs to be fixed, the limit screws are tightened to make it close to the track of the slide rail 21 to achieve the limit. Conversely, the limit screws are loosened to push the slider to move.

[0022] On the slider of the slide rail 21 , a mounting rod 5 is provided at an angle perpendicular to the upper gusset plate 2 , and a GNSS device 6 is fixedly mounted on the upper end of the mounting rod 5 .

[0023] During installation, first place the lower buckle plate 1 and the upper buckle plate 2 against the main cable 7 , and tighten the nuts appropriately, so that the GNSS equipment positioning device for main cable deviation monitoring clamps the main cable 7 .

[0024] Then, first adjust the nut at the lower end of the right positioning screw 4 to make the level bubble on the lower clasp plate 1 horizontal and centered; then adjust the nuts at the upper ends of the left positioning screw 3 and the right positioning screw 4 to make the level bubble on the upper clasp plate 2 horizontal and centered.

[0025] Observe the first scale on the lower gusset plate 1 to determine the scale corresponding to the axis of the main cable 7. Then slide the mounting rod 5 and the GNSS device 6 to move them to the same scale. Finally, fix the position of the mounting rod 5 and the GNSS device 6 to complete the installation.

[0026] Example 2

[0027] The difference from Example 1 is that: a sleeve 8 is coaxially arranged above the right through hole of the lower buckle plate 1; and sleeves 8 are coaxially arranged below the two through holes of the upper buckle plate 2. The inner diameter of the sleeve 8 is consistent with the inner diameter of each through hole, and they are aligned to form a channel. By providing the sleeve 8, the contact surface between the movable parts can be increased, thereby improving the adjustment accuracy.

[0028] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
