Detailed Description

The patent technology is further explained with reference to the drawings and the embodiments.

As shown in fig. 1 and 2, the wind-proof support device for preventing clamping stagnation of the present invention includes a bottom plate 1, a base 4, a sliding base 2, a speed reduction motor 5, a gear pair 6, a transmission shaft 7, a bearing seat 12, a universal joint nut 9, a screw 8, a support member 10, and a reinforcing structural member 11. The bottom plate 1 is fixed on the workbench 21 by bolts, the whole windproof supporting device is reinforced, the rigidity of the windproof supporting device meets the requirement of wind resistance, and the windproof supporting device is a mounting base of the whole windproof supporting device. The base 4 is fixed on the bottom plate 1, the speed reduction motor 5, the gear pair 6 and the bearing seat 12 are fixed on the bottom plate 1 through the base 4, and the transmission shaft 7 is installed on the bearing seat 12. The output shaft of the gear motor 5 is connected with a gear pair 6, and the gear pair 6 is connected with a transmission shaft 7 through a bearing support. The transmission shaft 7 is connected with the screw rod 8 through a bolt 17. The lead screw 8 is connected with the sliding column 3 on the universal joint nut 9, the sliding seat 2 is fixed on the bottom plate 1 through bolts, the sliding column 3 is installed in the sliding seat 2, and the lead screw 8 pushes the universal joint nut 9 to slide in the sliding seat 2, so that the sliding column 3 moves back and forth along the sliding seat 2. The two wind-proof supporting devices 20 are fixed at one end of the workbench 21 through the bottom plate 1 and the reinforcing structural member 11, and the wind-proof capability of the whole workbench 21 is enhanced.

As shown in fig. 1, the support member 10 of the present invention is fixed to the strut 3.

As can be seen from FIG. 2, when the spool 3 moves to this state (i.e. when the spool 3 is far from the base 4), the included angle α between the spool 3 and the sliding seat 2 becomes larger and larger, if a general nut is directly and fixedly connected with the spool 3 (i.e. the universal joint nut 9 is replaced by a general nut), the included angle α between the general nut and the sliding seat 2 becomes larger and larger, and when the included angle α eliminates the gap between the general nut and the lead screw 8, the lead screw 8 is easily subjected to a larger external force, and the lead screw 8 cannot rotate, and the system cannot normally work.

As shown in fig. 3, the universal joint nut 9 of the present invention includes a sliding column 3, a connection nut 13, a cross joint 14, a first pin 15, a first screw 16, a second pin 18, and a second screw 19, where the two first pins 15 are respectively perpendicular to the cross joint 14 and fixed on the cross joint 14, and the two first pins 15 must be coaxial to ensure that the connection nut 13 can deflect at any angle in the horizontal direction. The first pin shaft 15 is provided with a through hole and a first screw 16, the first pin shaft 15 is fixed on the connecting nut 13 through the first screw 16, and the first pin shaft 15 is arranged in a cross-shaped 14 shaft hole so as to rotate in the cross-shaped 14 shaft hole. The two second pins 18 are perpendicular to the sliding column 3 and fixed on the sliding column 3, and the two second pins 18 must be coaxial to ensure that the cross joint 14 can deflect at any angle in the vertical direction. The second pin shaft 18 is provided with a second screw 19 through a through hole, the second pin shaft 18 is fixed in the cross joint 14 through the second screw 19, and the second pin shaft 18 is arranged in the shaft hole of the sliding column 3 so as to rotate in the shaft hole of the sliding column 3. The axis formed by the two second pins 18 intersects perpendicularly with the axis formed by the two first pins 15, thus ensuring that the coupling nut 13 can be deflected at any angle with respect to the strut 3.

As shown in figures 2 and 3, the connecting nut 13 of the invention is provided with an inner hole, the inner hole is provided with threads, and the inner hole threads of the connecting nut 13 are arranged corresponding to the threads of the screw rod 8.

By utilizing the universal joint nut, after the adjusting screw rod 8 extends, when the included angle α is formed to eliminate the gap between the common nut and the screw rod 8, the universal joint nut 9 and the screw rod 8 can have a certain angle in any direction, so that the normal work of the screw rod 8 is ensured, and clamping stagnation and squeaking caused by friction can not occur.

The support members 10 of the present invention are preferably leveling legs, four support members 10 are installed on one work table 21, and after the four support members 10 are unfolded, the work table 21 of the whole apparatus is leveled by the leveling legs (increasing the schematic view). The working table 21 of the present invention may be a working table 21 such as an antenna vehicle, a lifting device, etc.

As shown in FIG. 4, the wind stand according to the present invention comprises a table 21 and 4 wind supports 20, wherein the 4 wind supports 20 are mounted on the table 21, and the wind supports 20 are fixedly mounted on the table 21 via a base plate 1 and a reinforcing structural member 11. When a large-scale device such as an antenna array is installed on the working table 21, if the wind speed is high, the whole working table 21 is greatly influenced by the wind, and in order to ensure that the working table 21 is not blown off, the four wind-proof supporting devices 20 are unfolded at this time, so that the supporting member 10 supports the ground, and the wind-proof capability of the whole working table 21 is improved.

In conclusion, the technology can effectively solve the clamping stagnation phenomenon of the screw rod pair under the action of external force and eliminate the squeaking sound caused by friction between the connecting nut and the screw rod.
