Embodiment Construction

[0071] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0072] Please refer to figure 1 , 2 , figure 1 It is a structural schematic diagram of locking the rail on the rail train by the locking mechanism provided by the present invention; figure 2 A zoomed-in view of the position of the locking mechanism locking the abutment beam.

[0073] Such as figure 1 As shown, the locking mechanism includes bases 10 located on both sides of the pallet 100 of the rail train, and the bases 10 are supported and fixed on the pallet 100 . The locking mechanism also includes a pressing device 40 and a supporting base 20. The two sides of the supporting base 20 are respectively supported on the base 10 on both sides. The base 10 can be supported and fixed on the supporting plate 100, which ...

Abstract

The invention discloses a locking mechanism for locking rails, which includes a pressing device, a locking device and a support base for supporting multiple rails; the pressing device includes a pressing beam and a pressing driving part; The driving part drives the pressing beam to rotate around one end thereof, so as to lock or unlock multiple rails by rotating and pressing; when the pressing beam clamps multiple rails, the locking device is used to Lock the other end of the compression beam. This scheme also uses a pressure beam to span multiple rails, and presses multiple rails from the top of the rails at the same time, so as to lock multiple rails at the same time, prevent the rails from moving in the longitudinal direction, and limit the rails from moving up and down. The efficiency of locking the rail can be greatly improved. In addition, by setting the locking device to lock the free end of the pressing beam, the reliability of pressing and locking of the pressing beam can be ensured, and the load requirement on the pressing driving part can be reduced.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a locking mechanism for locking rails. Background technique [0002] Rail trains are railway engineering vehicles used for loading, transporting, and unloading long rails. The rail train has a pallet on which the rails to be transported are generally arranged in a layer on the pallet, the number of which can reach dozens, and the length of a rail is usually 400m. [0003] In order to prevent the rail from moving longitudinally on the pallet, a locking device is generally provided. The current locking device mainly includes locking weights, locking blocks and locking bolts. There are a set of locking weights and locking blocks on both sides of the bottom of the rail. Between them, tighten the locking bolt manually to lock the locking weight iron and the locking weight block to lock the rail. Each steel rail will carry out such locking operation successively, and lock...
