Description

Technical Field

[0001] The utility model relates to the field of connection structures, in particular to a transfer connection structure. Background Art

[0002] When two connected structural parts need to bear heavy loads and high strength requirements and need to have good anti-torsion and anti-shear performance, there is usually shear force between the two and a tight connection is required. In this case, the hole center of the two structural parts to be connected is often prone to slight deviations due to processing accuracy issues, resulting in only hole expansion or reducing the diameter of the shear bolt used for connection. Both of these treatment methods will cause a gap between the shear bolt and the hole wall, causing the two connected structural parts to have a certain displacement under the action of shear force, resulting in a change in the relative position between the two structures, which greatly reduces the shear resistance of the shear bolt, and fails to exert the performance that the shear bolt should have and fails to meet the expected requirements.

[0003] Therefore, in the fields of industrial and civil construction, highway and railway bridges, lifting machinery, etc., where heavy loads and high strength requirements are required, shear bolts need to be used. There is an urgent need for a transfer connection structure to shift the original bolt holes of the two structural parts when they are not aligned, so as to improve the torsion and shear resistance of the connection between the two structural parts. Utility Model Content

[0004] The utility model aims to provide a transition connection structure to solve the problem that the shearing performance of the shear bolt is greatly reduced due to the hole center deviation of two structural members at the connection.

[0010] In some embodiments, when the first teeth and the second teeth are meshed with each other, the arcuate surface fits against the edge of the disk.

[0011] In some embodiments, the thickness of the fixing portion is equal to the width of the receiving groove.

[0012] In some embodiments, the width of the locking portion at one end close to the fixing portion is greater than the width of the other end.

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, if the term "connection" or the like appears to indicate the connection relationship between components, the term should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two components or the interaction relationship between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1-4The figure shows one specific embodiment of a transition connection structure. The transition connection structure includes a disc 1 for replacing the original bolt hole position, and a replacement hole 2 is provided on the disc 1. The diameter of the replacement hole 2 is the same as the diameter of the original bolt hole, and there is a spacing distance between the center of the replacement hole 2 and the center of the disc 1, so that the position of the replacement hole 2 can move with the rotation of the disc 1. The center of the disc 1 is within the coverage of the replacement hole 2, avoiding the need to drill a hole that is too large on the structural member. During use, the front and rear structural members cannot penetrate the original bolt hole due to the misalignment of the holes. At this time, a hole with the same diameter as the disc 1 is drilled on one of the structural members, and the original bolt hole on the structural member is removed. The position of the drilled hole is based on the rotation of the disc 1 to align the replacement hole 2 with the original bolt hole of the other structural member.

[0029] More specifically, a circle of accommodating grooves 3 are provided around the edge of the disk 1, and four anti-rotation members 4 are installed in the accommodating grooves 3. The anti-rotation member 4 includes an integrally formed locking portion 401 and a fixing portion 402. The fixing portion 402 is inserted into the accommodating groove 3, and a plurality of first teeth 403 are formed at the bottom of the fixing portion 402. A circle of second teeth 5 are formed along the outer circumference of the disk 1 at the bottom of the accommodating groove 3, and the first teeth 403 and the second teeth 5 can mesh with each other. The anti-rotation member 4 plays a role in strengthening the fixation of the disk 1. When in use, notches with the same shape as the locking portion 401 are continued to be cut around the hole opened on the structural member. When the replacement hole 2 is rotated to face the original bolt hole of another structural member, the four anti-rotation members 4 are also moved to the four corresponding notch positions. The fixing portion 402 is inserted into the accommodating groove 3 so that the first teeth 403 mesh with the second teeth 5, and then the disk 1 and the anti-rotation member 4 are inserted into the hole and notch opened on the structural member for welding. In the present embodiment, four anti-rotation members 4 are used as an example for illustration. More or fewer anti-rotation members 4 are also applicable to the present embodiment. For example, two anti-rotation members 4, six anti-rotation members 4, etc. are all applicable to the present embodiment.

[0030] Among them, the thickness of the stopper 401 is equal to the thickness of the disk 1, which is more conducive to the welding and fixing of the stopper 401 and the disk 1. The thickness of the fixing part 402 is less than the thickness of the stopper 401, and the thickness of the fixing part 402 is equal to the width of the receiving groove 3, so that the fixing part 402 can be stably inserted into the receiving groove 3 without shaking, and the structural strength after welding is greater. The two sides of the stopper 401 are provided with arc surfaces 404 matching the edge of the disk 1. When the first tooth 403 and the second tooth 5 are meshed with each other, the arc surface 404 fits with the edge of the disk 1. After welding, the anti-rotation member 4 is better combined with the disk 1, and then the anti-rotation member 4 is inserted into the notch opened on the structural member for welding, which further prevents the disk 1 from rotating.

[0031] In order to facilitate the locking portion 401 to be locked into the opening of the structural component, the width of the locking portion 401 at one end close to the fixing portion 402 is greater than the width of the other end. More specifically, the cross-sectional shape of the locking portion 401 is triangular, semicircular or trapezoidal.

[0032] like Figure 5 As shown, when the transfer connection structure of the utility model is used, in the case that the original bolt hole of the front and rear structural members cannot be penetrated by the bolt due to the misalignment of the holes, a hole with the same diameter as the disc is drilled on one structural member, and the original bolt hole on the structural member is removed. The position of the drilled hole is based on the rotation of the disc to align the replacement hole with the original bolt hole of the other structural member. The holes opened on the structural member are cut around the same shape as the stopper, and when the replacement hole is rotated to face the original bolt hole of the other structural member, the four anti-rotation members are also moved to the four corresponding notch positions, and the fixing part is inserted into the accommodating groove so that the first tooth and the second tooth are meshed, so that the anti-rotation member and the disc will not rotate relative to each other, and then the disc and the anti-rotation member are clamped into the hole and notch opened on the structural member, and each connection seam is welded to form a new structural member with a replacement hole facing the original bolt hole of the other structural member. At this time, shear bolts are used to connect, which can improve the shear resistance of the two connected structural members.

[0033] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
