Example 1

Traction connection devices for railway equipment, mostly referred to as: two carriages link together around with, drive another carriage by preceding carriage or back carriage and remove, reach and connect towed purpose, too complicated structure is unfavorable for simple quick connected mode, so take the key structure of bolt post as in the connection process in this scheme, specifically as follows:

referring to fig. 1, fig. 3 and fig. 4, a traction connection device for railway equipment, including preceding frame 1 and back frame 2, preceding frame 1 and back frame 2 all are three horn shapes, and preceding frame 1 and the one end that back frame 2 is close to each other are provided with preceding go-between 6 and back connector link 8 respectively, phase-match between preceding go-between 6 and the back connector link 8, and all seted up bolt mouth 7 on preceding go-between 6 and the back connector link 8, mounting panel 3 and support frame 12 have all been welded to preceding frame 1 upper and lower both sides position, it has movable bent plate 13 to articulate on the support frame 12, install bolt post 14 with bolt mouth 7 matching on the movable bent plate 13 one end position, mounting panel 3 is located and installs electronic pushing cylinder 11 on the movable bent plate 13 other end position, install vertical die-pin 10 that is vertical distribution on the transmission shaft of electronic pushing cylinder 11, phase-match between vertical die-pin 10 and the movable bent plate 13, clearance groove 15 has been seted up on the inside position of the movable bent plate 13 other end, clearance groove 15 has been seted up on the outer wall position of both sides movable spout 17, install the movable die-pin 16 that matches on the vertical die-pin 10 both sides outer wall position.

The working principle is as follows: firstly, in the using process, taking two sections of carriages on a railway as an example, wherein a front frame 1 and a rear frame 2 are respectively welded on the head and tail positions of the two sections of carriages, and the carriage on the front frame 1 is used as a main driving traction structure;

then the carriage connected with the front frame 1 approaches the carriage connected with the rear frame 2 until the front connecting ring 6 and the rear connecting buckle 8 are superposed with each other and the bolt openings 7 thereof are aligned, at the moment, the electric pushing cylinder 14 can be started to move the vertical supporting rod 10 upwards, the vertical supporting rod 10 moves in the movable sliding groove 17 through the movable pin 16, so that the movable curved plate 13 at the end is moved upwards, and correspondingly, the other end of the movable curved plate 13, which is provided with the bolt opening 14, moves downwards until the bolt opening 7 is completely inserted by the bolt opening 14, thereby completing the connection process of the front connecting ring 6 and the rear connecting buckle 8;

similarly, when the electric push cylinder 11 is reversely started, the other end of the movable curved plate 13, which is provided with the plug pin 14, moves upwards until the plug pin 14 is completely separated from the plug pin opening 7, so that the separation process of the front connecting ring 6 and the rear connecting buckle 8 is realized.

Example two

With reference to the first embodiment, the front frame or the rear frame is taken as the main driving structure, for example: the front frame is used as a driving traction structure, when the rear frame is driven to move forward, the rear frame is arranged on a train carriage, the weight is larger, namely in the traction process, the front frame and the rear frame are in a mutually-far state, the bolt columns are used as main stress structures, and the bolt ports on the front connecting ring and the rear connecting buckle can completely lock the bolt columns;

however, after the traction is finished, the rear frame continues to move towards the direction close to the front frame under the action of inertia force, and because the inertia is only related to the mass, the situation that the front frame does not move and the rear frame moves towards the front frame can be understood, the bolt holes in the front connecting ring and the rear connecting buckle can also completely lock the bolt posts, and the problem that the bolt posts are difficult to pull out and even cannot be pulled out exists, and the following technical scheme is provided for the purposes that:

referring to fig. 1 and 2, a stacked arch frame 4 is installed at an inner position of one side of a front frame 1, the stacked arch frame 4 is in an outward curved arch shape along a direction close to a rear frame 2, a movable guide rod 5 which is horizontally distributed is installed at a position, close to a center point of an outer wall of the rear frame 2, of the stacked arch frame 4, the movable guide rod 5 penetrates through the front frame 1 and extends to the inside of a front connecting ring 6, the movable guide rod 5 is in sliding connection with the front frame 1, the tail end, close to the rear frame 2, of the movable guide rod 5 is in a spherical shape, a contact ball groove 9 matched with the tail end of the movable guide rod 5 is formed in a rear connecting buckle 8, and the contact ball groove 9 is movably connected with the tail end of the movable guide rod 5.

The working principle is as follows: as mentioned above, the latch bolt 14 is a directly stressed structure, and during the towing process, two forces close to the front frame 1 and the rear frame 2 are respectively applied to the latch bolt 14, that is, under the two forces, the front connecting ring 6 and the rear connecting buckle 8 can completely lock the latch bolt 14, and the latch bolt 14 cannot be separated from the latch opening 7;

after the traction is finished, the carriage on the rear frame 2 continues to move towards the front frame 1 under the action of inertia force, then the latch posts 14 are pressed by the rear frame 2, the pressure direction points to the front frame 1, and the front connecting ring 6 and the rear connecting buckle 8 also have the problem of locking the latch posts 14;

it should be noted that, in the process of continuing to move the rear frame 2, the force is also transmitted to the laminated arch 4 through the movable guide rod 5, at this time, the laminated arch 4 is subjected to the pressure bending deformation from the rear frame 2, and then, under the effect of the resilience force thereof, the rear frame 2 is driven to be reset in the opposite direction until the latch openings 7 on the front connecting ring 6 and the rear connecting buckle 8 do not lock the latch posts 14, so that the latch posts 14 can be simply detached according to the content described in the first embodiment.

To sum up: the simplest bolt columns are used as main structures for connecting the front frame and the rear frame, the front frame and the rear frame are fixed from the upper side and the lower side, the bolt columns are controlled to move by the movable bent plates, the whole connection and separation processes are simple and direct, and in order to avoid the bolt columns being completely locked by the front connecting ring and the rear connecting port, the laminated arch frame is additionally arranged on the front frame, the laminated arch frame is used for driving the rear frame to reset, so that bolt ports on the front connecting ring and the rear connecting port are continuously kept in the state, and the bolt columns described on the laminated arch frame cannot be subjected to overlarge resistance in the separation process from the bolt ports, and even the problem that the bolt columns are difficult to pull out is caused.

The foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or exceeding the scope of the invention as defined in the claims.
