Problems solved by technology

This kind of mechanism is not only cumbersome to lock and unlock, but also cannot provide pre-tightening force in three directions at the same time, and does not have separation power after unlocking. It needs human pulling to separate the support car from the platform, which is time-consuming and labor-intensive.

Embodiment Construction

[0034] The present invention mainly provides a support car locking mechanism with separation power, including two parts: a front-end pre-tightening mechanism and a rear-end positioning mechanism. Safety device 104, mounting seat 105, vehicle beam 106, fixing nut 107, rubber pad 108, stop pile 109, stop pile side block 110 are composed of ten parts; the rear end positioning unit is fixed by the vehicle body positioning block 201 and the rear end The stopper 202 consists of two parts.

[0035] The rotary handle 101 and the ratchet screw sleeve 103 are integrally machined, and the outer ring of the ratchet screw sleeve 103 is provided with ratchet teeth. The ratchet screw sleeve 103 is installed on the mounting base 105 , and the ratchet screw sleeve 103 is fixed with a fixing nut 107 after passing through the mounting base 105 . The mounting seat 105 is welded on the vehicle beam 106 . The safety device 104 is installed directly above the ratchet screw sleeve 103, and the thim...

Abstract

The invention belongs to the technical field of mechanical structure design, and discloses a supporting vehicle locking mechanism which comprises two sets of front end pre-tightening units and rear end positioning units. The rear end positioning unit comprises a vehicle body positioning block fixed to the rear end of a supporting vehicle and a rear end fixing stop block fixed to a fixed platform. Each set of front end pre-tightening unit comprises a locking stud, a ratchet wheel threaded sleeve, a rotating handle, a mounting seat and a stop pile. The stop pile is mounted on the fixed platform; a first through hole is formed in the stop pile in the front-back direction of the supporting vehicle; the mounting seat is fixed on the front end side surface of the supporting vehicle; a second through hole is formed in the mounting seat; the locking stud is sleeved with the second through hole, and rectangular protrusions matched with the two rectangular through holes are symmetrically arranged on the two sides of the front end of the locking stud. The ratchet wheel threaded sleeve sleeves the locking stud and is positioned on one side, far away from the stop pile, of the mounting seat; a locking screw sleeve is in threaded connection with the locking stud; the rotating handle is fixed to the ratchet wheel threaded sleeve and drives the ratchet wheel threaded sleeve to rotate.

Description

technical field [0001] The invention belongs to the technical field of mechanical structure design, and relates to a locking mechanism for a supporting vehicle. Background technique [0002] The fixing of the support car and the platform is generally realized by a locking mechanism. Most of the previous support car locking mechanisms rely on the bolt and nut assembly to provide the pre-tightening force during locking. This kind of mechanism is not only cumbersome to lock and unlock, but also cannot provide preload in three directions at the same time, and does not have separation power after unlocking, requiring human pulling to separate the support car from the platform, which is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a supporting car locking mechanism, which can realize three-direction pre-tightening, and three-directional inclined surfaces can realize three-direction pre-tightening, and t...
