Embodiment Construction

[0025] As shown in the figure, a fixed seat 3 is installed under the truck-mounted boom 10, and the fixed seat 3 is clamped between the two screw rods 4 at the upper end of the fixed frame 1, and the pull ring 31 at the bottom of the fixed seat 3 is connected and fixed by the tensioner 2. Crossbar on rack 1. The fixed frame 1 is a triangular truss structure composed of two columns, two cross bars and two oblique bars. The bottoms of the two columns are hinged on the vehicle body, and two lugs 11 are installed on the uppermost cross bar. A shaft pin assembly 12 is installed on the lug 11, a stop rod 13 is located on the top of the fixed frame 1, and the stop rod 13 is located between the pull ring 31 and the stop ring 32 at the bottom of the fixed seat 3, and the stop rod 13 can block the stop ring 32 prevent it from turning further. There are screw sleeves 14 on the top of the two columns for installing the screw rod 4. The screw rod 4 includes a screw rod 42 and a top plate ...

Abstract

The invention discloses a self-adaptive marching fixing device for a vehicle-mounted suspension arm. The self-adaptive marching fixing device comprises a fixing frame (1), threaded sleeves (14) are arranged at the top ends of two stand columns of the fixing frame (1), rotary rods (3) are installed in the threaded sleeves (14), the two rotary rods (4) clamp a fixing base (3), and a pull ring (31) at the bottom of the fixing base (3) is connected with the fixing frame (1) through a tensioner (2). A tensioner structure is fixedly designed in the up-down direction, and the up-down direction can beadjusted. A screw precession type is designed in the left-right direction, the space gap in the left-right direction can be adjusted, and the requirement for adjustment in four directions is met. When the vehicle-mounted suspension arm returns, only fine adjustment is needed, the vehicle-mounted suspension arm can be fixed by roughly adjusting the truck-mounted suspension arm to the position above the fixing frame, fastening time is saved, and self-adaptive fixing is achieved.

Description

technical field [0001] The invention relates to a fixing device for a vehicle-mounted boom on vehicles such as a loading vehicle and a bomb carrier. Background technique [0002] Vehicles such as loading vehicles and ammunition carriers are equipped with truck-mounted booms. When marching, it is necessary to use marching fixtures to fix the truck-mounted booms. Usually, when the marching fixtures are in use, the truck-mounted booms need to be adjusted to the correct position of the fixing frame. At the top, use bolts or buckles to fix the truck-mounted boom. When it is not aligned, it needs to be adjusted back and forth many times until it is aligned, and it takes a long time to lock it. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixing device that can adapt to the position of the boom in view of the problem that the existing truck-mounted boom fixing device requires multiple adjustments to the boom.
