Description

Novel automatic supporting mechanism of central shaft transport vehicle

Technical Field

The invention discloses a novel automatic supporting mechanism for a transition springboard of a central shaft transport vehicle, and belongs to the technical field of cargo transportation.

Background

With the official promulgation of new GB1589, on the premise that the middle axle transport vehicle is of the same length and is not ultra wide, compared with a common car transport vehicle, the middle axle car transport vehicle can be provided with a plurality of vehicles, the middle axle transport vehicle is a main power vehicle type of the car transport vehicle in future, the middle axle transport vehicle consists of a vehicle transport vehicle and a middle axle transport trailer through a coupling device, when the vehicle passes to a front vehicle transport vehicle from the middle axle transport trailer, a transition springboard is required to be added in the middle to reduce the approach angle and the departure angle, at present, the domestic transition springboard supporting mechanism is required to be manually operated, the transition springboard is lifted to a certain height through an oil cylinder, the supporting mechanism is manually fixed, and then the transition springboard is lowered through the oil cylinder, so that the supporting mechanism falls on a platform, and the vehicle passes through. The mode is complex to operate, low in humanization degree and low in loading efficiency.

Disclosure of Invention

The invention aims to solve the technical problem of providing the novel automatic supporting mechanism for the transition gangway of the middle-axle transport vehicle, aiming at the prior art, the supporting mechanism rises along with the transition gangway in the lifting process of the transition gangway, and an operator only needs to operate a hydraulic valve handle in the whole process, so that the operation convenience and the loading efficiency are improved greatly.

The invention solves the problems by adopting the following technical scheme: the utility model provides a novel put axle transport vechicle transition gangway automatic stay mechanism in, it includes upset ratchet, guide block and upset support, the upset support includes permanent magnet steel bar and landing leg frame, and the permanent magnet steel bar is fixed in between the one end of two landing leg frames, the guide block symmetry welds in the front end below of transition gangway, and the upset ratchet passes through the fixed pin to be fixed respectively in the centre of guide block, and the one end that the upset was supported passes through torsion spring rotation with the frame and is connected, and the other end passes through permanent magnet steel bar and guide block magnetism actuation, the upset is supported when the transition gangway lifts up, and the permanent magnet steel bar end slides along the guide block, and the other end rotates to the permanent magnet steel bar can be used for the upset ratchet and make it rotate around the fixed pin when sliding, is crossing the upset ratchet, realizes the block locking that upset ratchet and upset support behind the decline transition gangway.

Compared with the prior art, the invention has the advantages that:

the invention can realize automatic support and automatic release of the transition springboard, only one person is required to operate the hydraulic valve handle in the loading process, the mechanism can shorten the loading time, improve the loading efficiency, realize intelligent operation and save labor cost.

Detailed Description

The present invention is described in further detail below with reference to examples.

Referring to fig. 1 and 2, the invention relates to a novel automatic intermediate shaft carrier transition springboard supporting mechanism, which comprises a turnover ratchet 3, a guide block 4, a base 5, a torsion spring 6, a pin shaft 7, a cotter pin 8, a turnover support 9, a fixing pin 10 and a limiting block 11. The overturning support 9 comprises a limiting blocking cover 12, hexagonal bolts 13, permanent magnet steel bars 14 and supporting leg frames 15, wherein the permanent magnet steel bars 14 are fixed between one ends of the two supporting leg frames 15 through the hexagonal bolts 13, and the limiting blocking cover 12 is arranged at two ends of the permanent magnet steel bars 14 and locked through the hexagonal bolts 13.

The guide blocks 4 are made of magnetic materials, the guide blocks are symmetrically welded below the front end of the transition springboard 2, the overturning ratchets 3 are symmetrically welded in a pair, the overturning ratchets 3 are respectively fixed in the middle of the guide blocks 4 through fixing pins 10, the overturning ratchets 3 can rotate around the fixing pins 10, the base 5 is welded on the frame 1, one end of the overturning support 9 is fixed on the base 5 through the torsion spring 6, the pin shaft 7 and the cotter pin 8, and the other end of the overturning support is magnetically attracted with the lower part of the guide blocks 4 through the permanent magnet steel rod 14. In a natural state, the permanent magnet steel rod 14 of the overturning support 9 is attracted to the guide block 4 in front of the overturning ratchet 3.

As shown in fig. 3, a novel lifting and locking flow of the intermediate shaft carrier vehicle transition springboard automatic supporting mechanism is as follows:

scheme 1: the transition springboard 2 is lifted, and the overturning support 9 is driven by the attraction force of the guide block 4 to rotate around the pin shaft through the permanent magnet steel rod 14.

Scheme 2: when the turning support 9 contacts with the turning ratchet 3, the turning ratchet 3 is pushed to rotate around the fixing pin 10, and after the turning support 9 passes over the turning ratchet 3, the turning ratchet 3 is restored to the original position by its own weight.

Scheme 3: the transition springboard 2 is lowered, and the overturning support 9 is clamped on the overturning ratchet 3.

As shown in fig. 4, a novel intermediate axle carrier vehicle transition springboard automatic supporting mechanism unlocking process is as follows:

scheme 1: the transition springboard 2 is lifted, so that the overturning support 9 is completely separated from the guide block 4, and the overturning support 9 is restored to a natural state under the action of the torsion spring 6.

Scheme 2: the transition springboard 2 is lowered, the overturning support 9 is contacted with the guide block 4, and the initial state is restored.

In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions that are formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
