Detailed Description

The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

Referring to fig. 1-2, the utility model provides a lifting device is folded to radar comprises every single move arm 1, support arm 2 and swing arm 3 for lift and receive and release the radar antenna, its simple structure, operation are stable, maintain convenient, can erect fast and remove the folding lifting device of radar who receives, satisfy the radar and lift the demand of the certain height work and the cross-country trafficability characteristic of transportation.

Specifically, referring to fig. 2, one end of the pitch arm 1 is fixed and rotatable about a fixed portion, and the other end of the pitch arm 1 is hinged to the swing arm 3. One end of the supporting arm 2 is hinged to the pitching arm 1, and the hinged position can be the middle position of the pitching arm 1 or can deviate from the middle position, and is designed according to specific conditions. The other end of the support arm 2 is hinged to a horizontal drive section.

In the present embodiment, the horizontal driving portion includes a slide block 6, a guide rail 8, a lead screw 7 and a power device 9, wherein the lead screw 7 may be a trapezoidal nut lead screw, etc., and the power device 9 may be driven by a speed reducer, a coupling, etc., without limitation. The other end of the supporting arm 2 is connected with a sliding block 6, the sliding block 6 is connected with a lead screw 7 through a lead screw nut, and the sliding block 6 is connected to a guide rail 8 through the lead screw 7; one side of the guide rail 8 is provided with a power device 9, and the screw 7 is connected with the power device 9; the power device 9 provides power for the lead screw 7, so that the lead screw 7 rotates, and the rotation of the lead screw 7 drives the sliding block 6 to move in the guide rail 8.
