Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a leading truck with anti-torque structure, including base 1, fixedly connected with connecting piece 2 on base 1, connecting piece 2 top fixedly connected with lower fixing ring 3, lower fixing ring 3 upper end is the cambered surface structure of undercut, 3 radial both sides of lower fixing ring all are equipped with integrated into one piece's first fixed block 4, first fixed block 4 upper end is equipped with first step 5, fixedly connected with upper mounting 6 on first

fixed block

4, 4 bottom fixedly connected with two bracing pieces 7 of first fixed block, bracing piece 7 bottom and base 1 fixed connection.

Specifically, the upper fixing piece 6 comprises an upper fixing ring 8, the bottom end of the upper fixing ring 8 is of an upward-concave cambered surface structure, and the two radial sides of the upper fixing ring 8 are provided with a second fixing block 9 which is integrally formed.

It is worth mentioning that, 9 bottoms of second fixed block are equipped with second step 10, second step 10 can cooperate with first step 5, first step 5 is the dislocation design each other with second step 10, can realize intermeshing, and there is great meshing area, first step 5 and second step 10 play the effect of antitorque square when can realizing first fixed

block

4 and 9 fixed connection of second fixed block, and then can effectually avoid the moment of torsion effect to act on the bolt to make the bolt of connecting first fixed block 4 and second fixed block 9 take place deformation, lead to first fixed block 4 and the fixed effect variation of second fixed block 9 and be difficult to the circumstances such as dismantlement to take place.

It should be noted that a first thread groove 11 is arranged on the first fixing block 4, a second thread groove 12 is arranged on the second fixing block 9, the axes of the first thread groove 11 and the second thread groove 12 which are located on the same side of the upper fixing ring 8 are located on the same straight line, and the first fixing block 4 and the second fixing block 9 are fixedly connected through the matching of bolts with the first thread groove 11 and the second thread groove 12.

Specifically, be equipped with integrated into one piece's fixed block 13 on the base 1,

bracing piece

7 and 13 lateral walls welded connection of fixed block will play the effect of support to first fixed block 4 when bracing piece 7 to will be to on the first fixed block 4.

Specifically, connecting piece 2 is narrow wide trapezium structure down on 3 radial directions of lower fixed ring, and then can realize that connecting piece 2 has enough strong supporting role on 3 radial directions of lower fixed ring, avoids the condition such as the lower fixed ring 3 lateral force that receives radial direction too big leading to the leading truck unstability to take place, and 2 tops of connecting piece pass through welded connection with 3 lower fixed ring, and 2 bottoms of connecting piece are through welding and 1 fixed connection of base.

Now, the operation principle of the present invention is described as follows:

the utility model discloses in when the moment of torsion exists, first step 5 and second step 10 intermeshing realize that the moment of torsion between upper fixed ring 8 and the lower fixed ring 3 is mainly concentrated between first step 5 and second step 10, area of contact between first step 5 and the second step 10 is great simultaneously, and then it is relatively poor to the destructive effect of first step 5 and second step 10 to realize the moment of torsion, and then play the anti-torque effect between upper fixed ring 8 and lower fixed ring 3, the moment of torsion that receives on the lower fixed ring 3 will transmit to fixed block 13 under bracing piece 7's effect simultaneously, fixed block 13 and base 1 integrated into one piece design, and then can ensure that the structure has sufficient stability, and then play the anti-torque effect to between lower fixed ring 3 and connecting piece 2.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
