Abstract
The utility model relates to a full trailer backing locking mechanism and its full trailer. The full trailer backing locking mechanism comprises a hook, a pin axle fixedly connected with the middle of the hook, a driving mechanism rotatably connected with the back part of the hook, a control mechanism for controlling the driving mechanism and a hook fixation seat in locking fit with the front part of the hook. The full trailer backing locking mechanism solves the positioning problem of the trolley frame and the trailer when the full trailer backs and an electric control switch control replaces the artificial near-distance operation positioning steel structure and the work danger is reduced and the backing accuracy is increased.
Description
Technical field
The utility model relates to a kind of independent trailer, especially with independent trailer trolley frame relevant with the connection structure between the trailer.
Background technology
Consult Fig. 1, adopt two-orbit rotating disk 3 to connect between existing independent trailer trolley frame 1 and the trailer 2, therefore the track center of circle with rotating disk 3 is that the center is free rotation state between trolley frame 1 and the trailer 2, when carrying out car backing operation, trolley frame 1 will occur retreating along different straight lines with trailer 2, even main car driver travel direction is adjusted, also the situation that trailer swings and retreats can occur, strengthen driver's operation easier, and the vehicle swing causes danger can for personnel on every side and device etc.
The existing main mode of independent trailer reversing gear has:
1. there is not the reversing registration device: have only rotating disk to connect between trolley frame and the trailer, be that the center is free rotation state with the track center of circle between the two, adjust about relying on driver individual to carry out fully, in actual mechanical process, because restrictions such as driver's experience and road place, have very big uncertainty, have higher threat.
2. armstrong's patent formula reversing registration device: promptly adopt pin or other nested structures, when reversing, trolley frame and trailer are rigidly connected, make both that mutual skew can not take place, realize straight line car-backing.Because the physical construction simple coarse easily lost efficacy, and need manually closely operation, have the hidden danger of personal life danger.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of more convenient, safe independent trailer reversing lockable mechanism of independent trailer reversing that makes.
For solving the problems of the technologies described above, the utility model provides a kind of independent trailer reversing lockable mechanism, comprise driver train that a hook, is rotatably connected with the hook rear portion with the bearing pin of hook middle part captive joint,, a controlling and driving mechanism action control mechanism and one with link up with the front portion and lock the hook permanent seat that cooperates.
Described independent trailer reversing lockable mechanism, wherein, described driver train is a cylinder, the free end of the piston rod of cylinder is provided with the U-shaped fork that the rear portion with described hook is rotatably connected.
Described independent trailer reversing lockable mechanism, wherein, described control mechanism comprises: the master cock of controlling the electromagnetic valve of described cylinder action and controlling described electromagnetic valve action, and described electromagnetic valve links to each other with described cylinder, and described master cock links to each other with described electromagnetic valve.
Described independent trailer reversing lockable mechanism, wherein, described hook permanent seat is the spill steel structure, is provided with in the recess of spill steel structure and links up with the stop block that cooperates.
For solving the problems of the technologies described above, the utility model also provides a kind of independent trailer, comprise trolley frame, trailer and above-mentioned reversing lockable mechanism, link to each other by rotating disk between trolley frame and the trailer, the driver train of reversing lockable mechanism is fixed on the described trailer, the bearing pin and the described trailer of reversing lockable mechanism are rotatably connected, and the hook permanent seat of reversing lockable mechanism is fixed on the described trolley frame.
Described independent trailer, wherein, described reversing lockable mechanism is two, is separately positioned on the position near the both sides of described rotating disk.
Useful technique effect of the present utility model is: realize stretching out of cylinder piston rod by the electric-controlled switch control electromagnetic valve, driving the bearing pin and the hook that are arranged on the trailer under the piston rod effect rotates, hook is tightened in the hook base that is arranged on the trolley frame, thereby realize being rigidly connected of trolley frame and trailer, can carry out straight line car-backing; When needing to remove, the electric-controlled switch control electromagnetic valve realizes the withdrawal of cylinder piston rod, under the effect of piston rod, drives bearing pin and rotates with hook, and hook is withdrawed from the hook base of trolley frame, and the reversing locking is removed, and can freely turn.The orientation problem of trolley frame and trailer replaced manually closely operation location steel structure with electric-controlled switch control when this independent trailer reversing lockable mechanism had solved the independent trailer reversing, had reduced operation danger, had improved the accuracy of reversing.
Description of drawings
Fig. 1 is the structural representation of existing independent trailer;
Fig. 2 is arranged on structural representation on the independent trailer for the utility model reversing lockable mechanism;
Fig. 3 is the detailed schematic of the utility model reversing lockable mechanism under open mode;
Fig. 4 is the detailed schematic of the utility model reversing lockable mechanism under lockup state;
Fig. 5 is the control principle figure of the utility model reversing lockable mechanism.
The specific embodiment
Consult Fig. 2, a pair of reversing lockable mechanism 4 is set on the independent trailer, this is separately positioned on position near the both sides of independent trailer rotating disk 3 to lockable mechanism 4, to pin down rotating disk, makes independent trailer can realize straight line car-backing when reversing, improves the accuracy of reversing.
Consult Fig. 3, Fig. 4, this independent trailer reversing lockable mechanism 4 comprise driver train 43 that the bearing pin 42, of a hook 41, one and hook 41 middle part captive joints is rotatably connected with hook 41 rear portions and one with link up with 41 front portions and lock the hook permanent seats 44 that cooperate.Bearing pin 42 is arranged on the trailer rotationally.Driver train 43 is fixed on the trailer 2, and in the present embodiment, driver train 43 is a cylinder, and the free end of the piston rod 431 of cylinder is provided with U-shaped fork 432, and U-shaped fork 432 is rotatably connected with the rear portion of hook 41.Hook permanent seat 44 is fixed on the trolley frame 1, and it is the spill steel structure, is provided with in the recess of spill steel structure and links up with 41 stop blocks that cooperate 441.
Fig. 5 is the control principle scheme drawing of reversing lockable mechanism, and as shown in the figure, master cock 433 links to each other with electromagnetic valve 434, and electromagnetic valve 434 links to each other with cylinder 43.When master cock was not closed, the piston rod 431 of cylinder 43 was in contraction state, and hook 41 is in disengaged position (as shown in Figure 3) with hook permanent seat 44 under the tension of piston rod 431.When master cock is closed, the piston rod 431 of cylinder 43 stretches out, hook 41 is under the thrust of piston rod 431, line of centers with bearing pin 42 is that center and bearing pin 42 overturn together, links up with the recess that 41 front portions snap in hook permanent seat 44, and with recess in stop block chucking (as shown in Figure 4), at this moment, trailer 2 is realized being rigidly connected with trolley frame 1, can carry out reverse action.
