The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0028] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.
[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0030] like Figure 1-3As shown, an upper cross arm bracket positioning system of the present invention positions the upper cross arm front bracket and the upper cross arm rear bracket, and the upper cross arm front bracket 17 and the upper cross arm rear bracket 18 are connected as one body, and the upper cross arm bracket positioning system includes:
[0031] Positioning base 6;
[0032] Two sliding guide rails 7 are provided on the positioning base 6 in parallel with each other;
[0033] A sliding platform 10 is slidably disposed on the sliding guide rail 7, and the sliding platform 10 can move forward and backward along the sliding guide rail 7;
[0034] Front positioning pin A8 and front positioning pin B9, one end of each of the front positioning pins A8 and B9 is detachably mounted in a mounting hole on the upper cross arm front bracket, and the other end of each of the front positioning pins A8 and B9 is inserted into a mounting hole of a front middle limit support 16, which is provided on the sliding platform 10;
[0035] The rear positioning pin A11 and the rear positioning pin B12, one end of the rear positioning pin A11 and the rear positioning pin B12 are respectively detachably installed in the mounting holes on the rear bracket of the upper cross arm, and the other end of the rear positioning pin A11 and the rear positioning pin B12 are then inserted into the mounting hole of the rear middle limit support 12, and the rear middle limit support 12 is set on the sliding platform 10.
[0036] The front positioning pin A, the front positioning pin B, the rear positioning pin A, and the rear positioning pin B are arranged in a straight line, and the front positioning pin A, the front positioning pin B, the rear positioning pin A, and the rear positioning pin B are arranged coaxially.
[0037] In the above implementation scheme, the present invention simultaneously utilizes the front positioning pin A8 and the front positioning pin B9, the rear positioning pin A11 and the rear positioning pin B12, as well as the front middle limit support 16 and the rear middle limit support 12 to simultaneously position the upper cross arm front bracket and the upper cross arm rear bracket, thereby solving the requirements for consistency of the upper cross arm front bracket 17 and the upper cross arm rear bracket 18 and the concentricity accuracy of the mounting holes, and separately positioning the upper cross arm front bracket and the upper cross arm rear bracket, using independent positioning sub-modules to ensure the individual size adjustment requirements of the brackets.
[0038] It should be noted that the sizes of the front middle limit support 16 and the rear middle limit support 12 are inconsistent. This is because the structural sizes of the upper cross arm front bracket 17 and the upper cross arm rear bracket 18 are not completely consistent, so they need to be adjusted according to actual conditions.
[0039] Another technical solution further includes a translation cylinder 15, whose telescopic end is connected to the sliding platform 10. The sliding platform 10 moves along the sliding guide rail 7 under the extension and contraction of the translation cylinder 15. The translation cylinder 15 is used to realize the movement of the entire positioning system, and the sliding platform 10 moves along the sliding guide rail 7, and the translation process can ensure good translation accuracy.
[0040] In another technical solution, the sliding platform is rotatably connected to the sliding guide rail 7 through a rotating shaft, so that the positioning platform can be folded or opened along the rotating shaft, which makes it easy to check the situation at the bottom of the sliding platform and facilitates operation and maintenance according to actual conditions.
[0041] In order to prevent the sliding platform 10 from falling off during the sliding process, another technical solution of the present application is further set up, including a limit block C5, which is located in front of the positioning base 6 and at the end of the sliding guide rail 7. The front limit block C5 is used to limit the sliding platform 10 and prevent it from falling off.
[0042] Another technical solution further includes a clamping cylinder, which is located below the sliding platform 7. The clamping cylinder drives the limit block A and the limit block B to move closer to / away from each other, and the upper cross arm front bracket and the upper cross arm rear bracket are connected as one and are located between the limit block A1 and the limit block B4. The limit block A1 and the limit block B4 can be used to further clamp the upper cross arm bracket as a whole.
[0043] Another technical solution further includes a manual cylinder, on which a gripper is provided for clamping the upper cross arm front bracket and the upper cross arm rear bracket, and the manual cylinder is controlled to start or close by a cylinder handle 3.
[0044] One embodiment of the present invention further provides a method for using the upper cross arm support positioning system, comprising the following operations:
[0045] Step S1: Push the cylinder handle 3 to clamp the upper cross arm front bracket and the upper cross arm rear bracket using the manual cylinder, and install one end of the front positioning pin A8 and the front positioning pin B9 in the mounting holes on the upper cross arm front bracket 17, and install one end of the rear positioning pin A11 and the rear positioning pin B12 in the mounting holes on the upper cross arm rear bracket 18;
