Detailed Description
The invention will be further explained with reference to the drawings.
The invention provides a traction assembly for transferring a tooling vehicle in a factory, which comprises a front traction assembly and a rear traction assembly which are respectively connected to the front part and the rear part of the tooling vehicle (not shown in the figure).
Referring first to fig. 3-5, there are shown perspective, top plan and front views, respectively, of a front hitch assembly in accordance with the present invention. The front traction assembly 1 comprises: a drawbar 11, a front coupling seat 12, a bolt 13, a cotter pin 14 and a locknut 15. The drawbar 11 is hinged to the front connecting seat 12 by means of a bolt 13, which bolt 13 is locked by a locking nut 15 and locked by a cotter pin 14.
The draw bar 11 is provided with a long hole 111 for the bolt 13 to pass through, and the long hole 111 is arranged along the extending direction of the draw bar 11. Therefore, as shown in fig. 3, at this time, the bolt 13 is placed at one end of the long hole 111 close to the front connecting seat 12, and after the drawbar 11 is rotated upward by 90 degrees from the state of fig. 3 in the horizontal direction with respect to the front connecting seat 12, the bolt 13 is placed at the other end of the long hole 111 far from the front connecting seat 12, so that the vertical locking of the drawbar 11 is realized, the drawbar does not need to be tied and fixed on the tooling vehicle by a rope or the like, the operation is convenient, and the hidden danger of breaking a product or a worker does not occur.
Preferably, a chamfer 112 is arranged above one end of the traction rod 11 close to the front connecting seat 12, so that the traction rod 11 can complete the rotation action.
in addition, the side surface of one end part of the traction rod 11 close to the front connecting seat 12 is a plane, and the gap between the traction rod 11 and the front connecting seat 12 is small, for example 10mm, so that the traction rod 11 is effectively horizontally limited. Further, the front connecting seat 12 is provided with a limiting block 121 below the traction rod 11, and when the traction rod 11 is in a horizontal state, the limiting block 121 can further prevent the traction rod 11 from rotating downwards, so that secondary horizontal limiting of the traction rod 11 is realized.
Still preferably, the upper portion of the draw bar 11 near the front connecting seat 12 is provided with a limit rod 113, and when the draw bar 11 is in a vertical state, the draw bar 11 cannot maintain the vertical state due to a gap between the draw bar 11 and the front connecting seat 12. The thickness of the limit rod 113 is equal to the gap, so that the limit rod 113 can fill the gap and ensure that the draw bar 11 can keep a vertical state. The limiting rod 113 may be in a cylindrical shape, so that the traction rod 11 can complete a rotating motion.
In addition, the other end of the drawbar 11, which is far from the front connecting seat 12, has a connecting hole 114 for connecting a towing device, and a reinforcing plate 115 having a hole is provided below the connecting hole 114 for reinforcing the end of the drawbar 11.
As further shown in fig. 6, which is a perspective view of a rear traction assembly according to the present invention, the rear traction assembly 2 includes: the rear connecting seat 21 is provided with three parallel pin racks 211, namely a first pin rack 211a, a second pin rack 211b and a third pin rack 211c from top to bottom, and the three pin racks 211a, 211b and 211c are provided with pin holes (not marked in the figure) in an aligned manner for inserting the rear pins 22. A spring 23 is sleeved on a section of the rear plug 22 between the first plug frame 211a and the second plug frame 211b, a limiting portion 24 is fixedly connected (e.g., welded) to the rear plug 22, the limiting portion 24 is located between the spring 23 and the second plug frame 211b, and a radial dimension of the limiting portion 24 is larger than a radial dimension of a plug hole on the second plug frame 211b, so that the limiting portion 24 cannot move from above the second plug frame 211b to below the second plug frame 211 b.
When the rear bolt locking device is used, the rear bolt 22 is made to exit from the position between the second bolt frame 211b and the third bolt frame 211c by the aid of the compression spring 23, then the part needing to be locked is placed between the second bolt frame 211b and the third bolt frame 211c, the rear bolt 22 is loosened, and the rear bolt 22 sequentially penetrates through the second bolt frame 211b and the third bolt frame 211c through resilience of the spring 23, so that locking is achieved. The bolt is realized can effectively avoiding coming off because of jolting the bolt that causes at the in-process of turnover with preceding connecting seat integrated design, and the design of no split pin is realized to the bolt moreover, convenient assembling.
In conclusion, the invention has the following beneficial effects:
1. Swing limiting of a traction rod of the front traction assembly: the draw bar can freely swing between a horizontal position (0 degree) and a vertical position (90 degrees) and is limited in the horizontal position and the vertical position;
2. the rear bolt and the rear connecting seat of the rear traction assembly are integrally designed: the bolt is realized avoiding losing with preceding connecting seat integrated design, and the bolt realizes not having the split pin design.
3. the work efficiency is improved: the quick alignment positioning is realized, the actions of inserting and pulling the cotter pin are reduced, the labor intensity is reduced, the time of about 5 seconds is reduced for a single tooling vehicle, and 5 tens of thousands of seconds are saved for 1 ten thousand tooling vehicles in a factory;
4. Promote product quality and reduce the potential safety hazard: when a product (such as a shell of the product) is turned over, the appearance requirement is high, and if the traction rod of the front traction assembly cannot be limited in a vertical state, the hidden danger of injuring the product is caused.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily make changes or variations within the technical scope of the present invention disclosed, and such changes or variations should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
