The utility model discloses a positioning inserted link capable of guiding, which is shown in fig. 1, and comprises an inserted link fixing seat 10, a plug 11 and a plug connecting part 12 for connecting the inserted link fixing seat 10 and the plug 11;
the plug connection portion 12 includes a frustum-shaped first connection portion 120 connected to the plug rod fixing base 10 and a cylindrical second connection portion 121 connected to the plug 11.
Specifically, as shown in fig. 2, the mechanical connector with the positioning insert rod disclosed by the utility model further comprises a limiting clamping sleeve 2, wherein the limiting clamping sleeve 2 comprises a limiting clamping sleeve body 20 and a plurality of elastic sheets 21 which are arranged at one end of the limiting clamping sleeve body 20 and are circumferentially arranged along the limiting clamping sleeve body 20, and when no inclination exists between the positioning insert rod and the limiting clamping sleeve, a plug of the positioning insert rod can be smoothly inserted between the elastic sheets of the limiting clamping sleeve along the direction of A in the figure so as to realize clamping connection between the positioning insert rod and the limiting clamping sleeve; as shown in fig. 3, when a certain angle of inclination exists between the positioning insert rod and the limiting sleeve, in the plug insertion process, due to the fact that the cylindrical second connecting portion is arranged on the positioning insert rod, the second connecting portion interacts with the inner wall of the limiting sleeve body, namely, the limiting sleeve body plays a role in guiding and correcting the positioning insert rod, so that the positioning insert rod rotates around the direction shown by an arrow D in the drawing, and the inclination between the positioning insert rod and the limiting sleeve is eliminated, as shown in fig. 4. Therefore, the positioning inserted link disclosed by the utility model can not cause transitional wear due to inclination between the positioning inserted link and the limiting clamping sleeve, and the problem of influence on the connection performance of the mechanical joint is solved.
Further, the plug 11 is provided with a double-dovetail taper clamping table 11, correspondingly, the inner wall of the elastic sheet is provided with a double-dovetail taper clamping groove, and preferably, the diameter of the small diameter end of the double-dovetail taper clamping groove is smaller than or equal to that of the small diameter end of the double-dovetail taper clamping table when the elastic sheet of the limiting clamping sleeve is in a free state. In the utility model, as the double-dovetail taper clamping table and the double-dovetail taper clamping groove are respectively arranged on the plug and the spring plate, a double-dovetail taper wedge clamping structure is formed between the plug and the spring plate, and the diameter of the small diameter end of the double-dovetail taper clamping groove is smaller than or equal to that of the small diameter end of the double-dovetail taper clamping table when the spring plate of the limiting clamping sleeve is in a free state, so that when the plug is inserted into the limiting clamping sleeve, the two groove edges of the double-dovetail taper clamping groove can be clamped with the double-dovetail taper clamping table in any state, the problem that the axial free gap exists between the spring plate and the plug of the traditional mechanical connector, so that the pulling resistance and the shearing resistance of the connection of the precast concrete pile are reduced is solved, particularly, as shown in figures 5 to 8, wherein, figures 5 and 6 are that the diameter of the small diameter end of the double-dovetail taper clamping groove is equal to the diameter of the small diameter end of the double-dovetail taper clamping table and the plug is inserted into the spring plate, the plug is just in a fully clamped state with the spring plate, in this state, the double-dovetail taper clamping groove is fully attached to the double-dovetail taper clamping table, at this time, the plug is in surface contact clamping with the spring plate, fig. 7 and 8 show that the diameter of the small diameter end of the double-dovetail taper clamping groove is equal to the diameter of the small diameter end of the double-dovetail taper clamping table, and after the plug is inserted into the spring plate, the plug has a certain axial free L (the insert rod is inserted into the spring plate or is not inserted into the spring plate to a certain extent) or the diameter of the small diameter end of the double-dovetail taper clamping groove is smaller than the diameter of the small diameter end of the double-dovetail taper clamping table, at this time, when the plug is inserted into the spring plate of the limiting clamping sleeve, the edges of the two grooves of the double-dovetail taper clamping groove are clamped with the double-dovetail taper clamping table, namely, in the whole axial free surface (the taper surface of the double-dovetail taper clamping table), and an axial free gap is not formed, so that the pulling resistance and the shearing resistance between the precast concrete piles are ensured when the mechanical joint disclosed by the utility model is adopted for connecting the precast concrete piles.
Further, because at least two groove edges of the double-dovetail taper clamping groove are clamped with the double-dovetail taper clamping table in any state of clamping the inserted link and the limiting clamping sleeve (for example, when the diameter of the small diameter end of the double-dovetail taper clamping groove is equal to the diameter of the small diameter end of the double-dovetail taper clamping table and the plug is just in a state of being completely clamped with the elastic piece, the double-dovetail taper clamping groove is in surface contact with the double-dovetail taper clamping table, when the diameter of the small diameter end of the double-dovetail taper clamping groove is smaller than the diameter of the small diameter end of the double-dovetail taper clamping table or when the diameter of the small diameter end of the double-dovetail taper clamping groove is equal to the diameter of the small diameter end of the double-dovetail taper clamping table and the plug is not in a state of being completely clamped with the elastic piece, the double-dovetail taper clamping groove is in contact with two edges of the double-dovetail taper clamping table, namely each elastic piece is in contact with the plug in two lines, namely the contact area of the elastic piece and the plug is increased, particularly, the double-dovetail taper wedge clamping structure is adopted, the number of contact points of the elastic piece and the plug is multiplied by 4 times, compared with the number of contact points of the existing mechanical structure, the number of contact points of the elastic piece and the plug is increased by 4 times, as shown in the figure 8, the contact points are A1-A8, so that the deformation amount between the elastic piece and the plug is greatly reduced relative to the existing mechanical connector under the action of the pulling force or the shearing force of the plug, and the axial movement amount of the inserting rod along the inserting rod caused by deformation of the pulling force or the shearing force of the plug is reduced, and the pulling resistance and the shearing resistance of the precast concrete pile are further improved.
Further, the taper a of the double-dovetail taper clamping table is 30 degrees to 60 degrees, so that good mechanical connection performance can be obtained.
Further, the teeth are provided on the double dovetail taper clamping table 110, so that the pulling resistance of the pile connection can be further improved.
Further, the length of each dovetail taper clamping table in the double dovetail taper clamping table is greater than or equal to 7mm. The length of each dovetail taper clamping table is greater than or equal to 7mm, so that even if a certain gradient exists on the end face of a concrete pile or a certain pile perpendicularity error exists during concrete piling, a certain axial free distance exists between plug insertion elastic sheets, the axial free distance is still smaller than the length of each dovetail taper clamping table, further, the insertion rod and the limiting clamping sleeve can be clamped together effectively, and accordingly connection reliability of precast concrete piles is guaranteed.
Further, the insert rod fixing seat 10 is further provided with a clamping structure 100 for clamping when the insert rod 1 is installed. The clamping structure is arranged on the inserted rod fixing seat 10, so that the inserted rod can be conveniently clamped by using a clamping tool to be installed when the inserted rod is installed, and in the embodiment, the clamping structure is a polygonal structure arranged between the inserted rod connecting part and the inserted rod fixing seat.
Further, the end part of the plug 11 is further provided with a guiding conical surface 111, and the guiding conical surface is provided to facilitate the plug to be inserted into the limiting clamping sleeve and reduce the abrasion between the plug and the limiting clamping sleeve in the process of inserting the plug into the limiting clamping sleeve.
Further, the inserted link fixing seat 10 is provided with external threads so as to be in threaded connection with end plates or nut sleeves at two ends of the precast pile.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
