Problems solved by technology

However, the antenna in the vehicle system often puts forward certain requirements on the height of the electric lift mast, so the closed height of the electric lift mast itself cannot be compressed without limit, resulting in the inability to meet the height requirements of air transportation for vehicles

Embodiment Construction

[0024] Reference Figure 1-Figure 4 To illustrate, the installation of the electric lifting rod lifting mechanism includes the basin 2, the sealing support ring 4, the lifting frame 5, the shock absorber 6 and other components. The seal support ring is composed of a seal ring 15, a rubber guide sleeve 17, a pressure plate 18, a connecting plate 19, etc.; the lifting frame includes a movable bottom frame 9, a bracket 10, a guide rail 11, a screw assembly 12, a slider 13, and the like.

[0025] A lifting mechanism for a vehicle-mounted electric lifting rod includes a lifting rod 1 for stretching to lift an antenna. The lifting rod is set up on a lifting mechanism for lifting the lifting rod, and the lifting mechanism drives the lifting rod to a vertical direction When raising and lowering, the lifting mechanism includes a base frame 9 as a fixed reference, a setting 12, a guide rail, and a movable bracket. The lead screw is installed on one side of the base frame, and a guide rail ...

Abstract

The invention discloses a lifting mechanism of a vehicle-mounted electric lifting rod. The lifting mechanism comprises a lifting rod for stretching to lift an antenna, the lifting rod is arranged on araising mechanism for lifting the lifting rod, and the raising mechanism drives the lifting rod to ascend and descend in a vertical direction. The raising mechanism comprises a bottom frame serving as a fixed reference, a lead screw component, guide rails and a movable bracket, the lead screw is assembled on one side of the bottom frame, each of two sides of the lead screw is provided with a guide rail, the movable bracket is assembled on the guide rails in a sliding mode, and the movable bracket is connected with the lead screw in a driving mode through a lead screw base. According to the lifting mechanism of the invention, the height of an electric lifting rod on a carrier vehicle can be adjusted at will within a certain stroke range so as to adapt to different using environments of thevehicle, and the passing ability is improved. The lifting mechanism has the characteristics of compact structure, simplicity in operation, self-locking, low cost and the like.

Description

Technical field [0001] The invention relates to a mechanical lifting mechanism, in particular to a lifting mechanism of a vehicle-mounted heavy-duty electric lifting rod with arbitrarily adjustable height and vibration isolation function. Background technique [0002] With the improvement of the mobility of high-mobility vehicles, higher requirements are put forward for the vehicles in road transportation, railway transportation, air transportation, and off-road driving, especially for the height of the vehicle in air transportation. . The installation of on-board electric lift rods is often an important factor that restricts the off-road capability and height of the vehicle. It often needs to be installed in the middle or rear of the vehicle. When installing in the middle, consider the height of the chassis underframe as an electric lift rod. The lowest point of the electric lifter must be calculated by considering the departure angle when installed in the rear. However, the a...
