Embodiment 1

[0033] refer to Figure 1 ~ 6 As shown, a axle fixing device includes a frame 1, a axle 2, a fixed support 3, a hook mount 4, a hook 5, a swing cylinder 6, a secondary locking device 7, and a constraging mechanism 8.

[0034] The axle 2 rotates to increase in the circular hole of the fixed support 3, the fixing support 3 and the hook mount 4 are fixed to the frame 1. The axle 2 is provided on the axle 2, hinged hook 5 hinges 5, and the curved surface of the hook is attached to the vehicle hook plate. The hook 5 is provided with a hook-locking hole 52, and the hook-locking hole 52 is fitted to the secondary locking device 7, which can realize the secondary lock of the axle.

[0035] The axle 2 includes a bus shaft pad 21 that is welded to the shaft body, and the axle pad 21 is provided with opposite two, and there is a mount hole 211 on the axle pad 21, and the launched pin 22 is fixedly welded in opposing two-pin hole. In 211, the axle-locking plate 21 is provided with a hose locki...

Abstract

The invention discloses an axle fixing device which comprises an axle and a hook mounting seat, wherein a hanging pin is arranged on the axle, a hook is hinged to the hook mounting seat, the hook is matched with the hanging pin, a hook locking hole is formed in the hook, and the hook locking hole is matched with a secondary locking device. The device has the beneficial effects that a secondary locking round pin penetrates through the hanging plate locking hole to form a closed fixing form, so that the risk that the hook is separated from the hanging pin under the impact working condition of railway application due to the fact that the contact surface of the existing hook and the hanging pin is in arc contact and the closed form is not formed is solved; and the problems that after a container is loaded through an existing structure, the connection degree of the hook and the hanging pin cannot be observed, no virtual connection cannot be guaranteed, and the operation safety cannot be guaranteed are solved.

Description

Technical field [0001] The present invention belongs to the vehicle mechanical apparatus, specifically a axle fixing device. Background technique [0002] Semi-trailers typically use air suspensions, air suspensions generally have overall lifting functions, and is applied to single-axis or multi-shafts. For the two-purpose semi-trailer of the public iron, in order to adapt to the road self-running and rail carrier operation, the air suspension uses the separable structure to accommodate different transport modes, and the semi-trailer is running in the railway, requiring the axle wheel to improve After the carrying operation needs to be fixed to the axle, complete the railway back run, the axle fixation, down the axle and the wheel restore the road operation mode. [0003] Patent Publication No. CN109572347A discloses a common iron dual-use semi-trailer fixture, the hook of the apparatus is rotated by the cylinder driving, and the axle is fixed and fixed by the axle lift, but the ...
