Furthermore, in the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
As shown in fig. 1 and 2, a split column mechanism is disclosed in this embodiment, comprising a first column member 1 and a second column member 2,
the first end of the first upright member 1 is provided with a mounting groove 3 extending in the axial direction thereof;
the second column part 2 comprises an expanded pipe part 21 and a butt joint part,
the second column member 2 can be inserted into the mounting groove 3, a part of the second column member 2 positioned in the mounting groove 3 can be expanded towards the inner side wall of the first column member 1 to form the expansion pipe part 21, and the rest of the second column member 2 can form the butt joint part;
a first gap is formed between the butt joint part and the inner side wall of the first upright post member 1 in the direction perpendicular to the axis, a second gap 4 is formed between the expansion pipe part 21 and the inner side wall of the first upright post member 1 in the direction perpendicular to the axis, and the ratio of the first gap to the second gap 4 is 1.9-2.1;
the expanded pipe portion 21 and the corresponding portion of the first column member 1 are all recessed inward by a riveting process to form a riveting portion 5 fixedly connected to each other.
In the above manner, the first upright post member 1 and the second upright post member 2 are combined and riveted by adopting split type splicing action, so that the shrinkage tube process in the prior art is completely replaced, the phenomenon of bending, cracking and the like at the fixed connection position of the first upright post member and the second upright post member due to the application of external force can not be caused by the use of the riveting process, and the deformation is not easy to occur while the work can be effectively completed; in addition, it is worth noting that by adopting the tube expansion process, the radial gap between the two is reduced while the two are convenient to install, and the deformation of the second upright post positioned inside can be improved by 3-4 times in the subsequent riveting process, so that the connection between the first upright post piece 1 and the second upright post piece is ensured to be more compact and firm.
In this embodiment, the first pillar member 1 and the second pillar member 2 may be hollow tubular, and may be made of Q235 steel material. By adopting the arrangement mode, the required strength in effective work is ensured, meanwhile, the weight can be reduced, the working procedures such as installation and carrying are convenient, and the production cost can be reduced.
Referring to fig. 1, the second column member 2 in this manner does not have a tube expansion portion 21. In particular, the second column member 2 has an outer diameter of 38mm, which can be easily inserted into the hollow cavity of the first column member 1. As can be seen from the sectional portion in fig. 1, a gap of 2.4mm is formed between the outer side wall of the second pillar member 2 and the inner side wall of the first pillar member 1 in the radial direction, and after the riveting force is applied, the inward recess of the side wall of the second pillar member 2 is 0.6mm, so that the riveted portion between the first pillar member 1 and the second pillar member 2 is smaller, and thus when a larger external force is applied to the post mechanism after connection, loosening of the riveted portion may be caused, and further hidden danger of riveting failure occurs.
Referring to fig. 2, the second column member 2 in this manner has a tube expansion portion 21. In particular, the second column member 2 has an outer diameter of 38mm, which can be easily inserted into the hollow cavity of the first column member 1. As is apparent from the sectional view of fig. 2, the portion of the second column member 2 inserted into the first column member 1 is expanded to form the expanded pipe portion 21, and a gap of about 1.15mm is formed between the outer side wall of the expanded pipe portion 21 and the inner side wall of the first column member 1 in the radial direction, and the gap is reduced by about 2 times with respect to the process without expanding the pipe. The riveting force is applied to the outer side wall of the first upright post 1 in the horizontal plane, after the riveting force is applied, the first upright post 1 and the second upright post 2 are recessed inwards to form the riveting part 5, wherein the inward recess of the side wall of the second upright post 2 is 2.1mm, which is about 3.5 times larger than that of the first upright post 1 and the second upright post 2 without the pipe expanding process, so that the riveting part between the first upright post 1 and the second upright post 2 is larger, and the loosening of the riveting part is basically not caused when a larger external force is applied to the post mechanism after connection, and the hidden danger of riveting failure is effectively reduced.
In this embodiment, the ratio of the lengths of the expanded pipe portion 21 and the connecting portion 22 in the axial direction is between 0.48 and 0.52. Specifically, the length of the expanded pipe portion 21 is 85mm, and the length of the connection portion 22 is 170mm. In the above arrangement, when the connection portion 22 located outside the first upright member 1 is satisfied to effectively butt-joint the external member, the expanded pipe portion 21 with a sufficient length is also left, so as to satisfy the subsequent riveting operation, so that the first upright member 1 and the second upright member 2 after riveting have better tightness, firmness and the like
In this embodiment, the first column member 1 and the second column member 2 are concentrically arranged, and the concentricity error between the first column member 1 and the second column member 2 is not greater than 0.5mm. According to the arrangement mode, after the riveting process, the concave amount of each riveting part 5 can be ensured to be basically consistent, so that under the application of external force, each riveting part 5 can be ensured to have better bearing force, the phenomena of loosening or failure and the like are reduced, and the connection firmness of the first upright post piece 1 and the second upright post piece 2 is ensured.
In this embodiment, the surfaces of the first pillar member 1 and the second pillar member 2 are provided with a zinc plating layer, preferably, the thickness of the zinc plating layer is between 75 and 100 μm. By adopting the arrangement of the galvanized layer, the first upright post piece 1 and the second upright post piece 2 have better corrosion resistance, wear resistance and other characteristics, and particularly the characteristic performance is particularly outstanding in outdoor working environments, multiple disassembly and installation procedures and the like.
The embodiment also discloses a split cylinder installation method, which comprises the following steps:
the first column part 1 is placed in the installation position. Specifically, the first column member 1 is vertically placed at the installation position and fixed, and preferably, the first column member 1 has an outer diameter of 48.3mm and an inner diameter of 42.9mm.
The first end of the second column member 2 is concentrically inserted into the mounting groove 3 of the first column member 1 to the machining position, and the relative positions of the first column member 1 and the second column member 2 are maintained unchanged. In particular, the second column element 2 has a total length of 255mm, a length capable of being inserted into the first column element 1 of 90mm, notably an error in concentricity between the first column element 1 and the second column element 2 of not more than 0.5mm. The theoretical preset value is that the gap formed between the expansion pipe part 21 and the inner side wall of the first column member 1 in the radial direction is 1.15mm.
And a pipe expanding process is adopted for the insertion part of the second upright post member 2, so that the gap between the second upright post member and the first upright post member 1 is reduced from 2.3-2.5mm to 1.1-1.2mm. It is noted that, where the length of the expanded tube portion 21 is 80mm, the theoretical preset value of the gap formed between the expanded tube portion 21 and the inner side wall of the first column member 1 in the radial direction is 1.15mm.
At least one set of riveting forces is applied to the first upright member 1 along the direction perpendicular to the axis of the first upright member 1, and each set of riveting forces is composed of a plurality of riveting forces uniformly distributed along the axis of the first upright member 1. Specifically, the caulking force is provided in two groups in the axial direction of the first pillar member 1.
The first column part 1 and the second column part 2 can be inwards recessed under the action of each riveting force and are mutually fixed with riveting parts 5, wherein the recess of the riveting parts 5 is between 2.0 and 2.2 mm.
In the above arrangement, compared with the second column member 2 without the tube expansion portion 21, the gap between the second column member 2 with the tube expansion portion 21 and the first column member 1 in the radial direction is reduced by 2 times, so that the recess of the subsequent riveting portion 5 is increased by about 3.5 times compared with the case of no tube expansion process, the riveting portion between the first column member 1 and the second column member 2 is larger, and thus, when a larger external force is applied to the post mechanism after connection, loosening of the riveting portion is basically not caused, and hidden danger of riveting failure is effectively reduced.
The embodiment also discloses a portal frame, which is shown in fig. 3, and comprises a split type column mechanism and a beam member 6, wherein at least two beam members 6 are arranged, two first column members 1 and two second column members 2 which are arranged corresponding to the first column members 1 are arranged, the two first column members 1 are respectively positioned on two opposite sides of the two beam members 6, and the two first beam members 6 and the two first column members 1 are relatively fixed and then can be enclosed to form a closed-loop portal frame.
Wherein the mast further comprises a corner plate member 7, said corner plate member 7 being arranged at the junction of said cross member 6 and said first column member 1. The arrangement of the angle plate piece 7 can effectively provide just strengthening hardness for the formed closed-loop type door frame, so that the closed-loop type door frame is ensured to still have better stability when being subjected to external force.
The principles and embodiments of the present invention have been described in detail with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
