[0041] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the term "and / or" in the specification and claims refers to at least one of the connected entities, and the character " / " generally indicates an "or" relationship between the connected entities.

[0043] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] like Figures 1 to 2 As shown, the tie bar installation device for a steel bar skeleton provided by an embodiment of the present invention includes: a bracket 1, a walking mechanism 2, a rotating mechanism, a lifting mechanism 3 and a tie bar connecting mechanism 4.

[0046] The lifting mechanism 3 includes a cylindrical housing 31, a primary telescopic tube 32 inserted within the cylindrical housing 31, and a secondary telescopic tube 33 inserted within the primary telescopic tube 32. The cylindrical housing 31, the primary telescopic tube 32, and the secondary telescopic tube 33 are coaxially coupled. The primary telescopic tube 32 can move axially relative to the cylindrical housing 31, and the secondary telescopic tube 33 can move axially relative to the primary telescopic tube 32.

[0047] One end of the cylindrical shell 31 away from the primary telescopic tube 32 is provided on a rotating mechanism, and the rotating mechanism is provided on the bracket 1 through the traveling mechanism 2. Driven by the rotating mechanism, the cylindrical shell 31 can rotate relative to the bracket 1, that is, the primary telescopic tube 32 and the secondary telescopic tube 33 can rotate synchronously with the cylindrical shell 31 relative to the bracket 1.

[0048] For example, an installation space is provided at the bottom of the walking mechanism 2, the top of the cylindrical shell 31 is provided in the installation space, an annular slide groove is provided in the installation space, and a guide rail portion is provided on the circumferential side of the top of the cylindrical shell 31. The shape of the guide rail portion is adapted to the shape of the annular slide groove, and can be installed in the annular slide groove and can rotate relative to the annular slide groove.

[0049] The traveling mechanism 2 can drive the rotating mechanism to move relative to the bracket 1, and the lifting mechanism 3 can also move accordingly. Among them, the traveling mechanism 2 can adopt various methods such as telescopic cylinder, screw drive, gear rack drive, etc. to achieve linear reciprocating motion.

[0050] The tie bar connecting mechanism 4 includes a first tie bar clamping assembly 41, a second tie bar clamping assembly 42 and a welding part 43. The first tie bar clamping assembly 41 is arranged on the periphery of the first-level telescopic tube 32, and the second tie bar clamping assembly 42 is arranged on the periphery of the second-level telescopic tube 33. The welding part 43 is used to weld the first tie bar 51 clamped by the first tie bar clamping assembly 41 and the second tie bar 52 clamped by the second tie bar clamping assembly 42.

[0051] The welding member 43 may be provided on any one of the first tie bar clamping assembly 41 and the second tie bar clamping assembly 42 or on both of them.

[0052] It should be noted that the first tie bar clamping assembly 41 and the second tie bar clamping assembly 42 can clamp the first tie bar 51 and the second tie bar 52 respectively. For example, the tie bar clamping assembly can achieve stable picking up of the tie bar through magnetic adsorption, pressure difference adsorption or claw grasping.

[0053] In the embodiment of the present invention, the first tie bar clamping assembly 41 clamps the first tie bar 51, and the second tie bar clamping assembly 42 clamps the second tie bar 52. After the clamping is completed, the walking mechanism 2 drives the lifting mechanism 3 to move a certain distance, so that the tie bar connecting mechanism 4 moves to the top of the steel frame where the tie bar needs to be installed. After moving to the target position, the first telescopic tube 32 moves relative to the cylindrical shell 31, so that the first tie bar clamped by the first tie bar clamping assembly 41 is located above the upper tie bar connection point, and the secondary telescopic tube 33 moves relative to the first telescopic tube 32, so that The second tie bar clamped by the second tie bar clamping assembly 42 is located below the lower tie bar tie point, and then driven by the rotating mechanism, the first tie bar, the upper tie bar tie point, the second tie bar and the upper tie bar tie point are made collinear, and then the first-level telescopic tube 32 and the second-level telescopic tube 33 continue to adjust their positions so that the first tie bar abuts against the upper tie bar tie point, and the second tie bar abuts against the lower tie bar node; finally, the first tie bar and the second tie bar are welded via the welding part 43. This method greatly improves the installation efficiency and quality of the steel skeleton tie bars.

[0054] In an optional embodiment, if Figure 3 As shown, the first tie bar clamping assembly 41 includes a first clamping jaw 411 and a first mounting seat 412, and the first clamping jaw 411 is arranged on the outer periphery of the first telescopic tube 32 through the first mounting seat 412; the second tie bar clamping assembly 42 includes a second clamping jaw 421 and a second mounting seat 422, and the second clamping jaw 421 is arranged on the outer periphery of the second telescopic tube 33 through the second mounting seat 422.

[0055] The first tie bar 51 held by the first clamping jaw 411 and the second tie bar 52 held by the second clamping jaw 421 can be butted together. The first tie bar 51 includes a first straight portion and a first bent portion extending from the first straight portion, and the second tie bar 52 includes a second straight portion and a second bent portion extending from the second straight portion. The butting of the first and second tie bars 51, 52 means that the first and second straight portions can be coaxially arranged.

[0056] Among them, the shape of the first mounting seat 412 is not limited, such as "L"-shaped, "U"-shaped, "O"-shaped or "square" shape, etc. For example, the first mounting seat 412 can be a tube structure with a round inside and a square outside, and is sleeved on the outer periphery of the first-stage telescopic tube 32. In addition, the first mounting seat 412 is arranged near the second-stage telescopic tube 33 of the first-stage telescopic tube 32, so that the first-stage telescopic tube 32 has the maximum telescopic ability. A first clamping jaw 411 is provided on the side of the first mounting seat 412 facing away from the first-stage telescopic tube 32, and the opening and closing of the first clamping jaw 411 can realize the grasping of the first tie bar 51.

[0057] In addition, the second tie bar clamping component 42 can have the same structure and installation position as the first tie bar clamping component 41, which will not be elaborated here.

[0058] In an alternative embodiment, as Figure 3 shown, the first tie bar clamping component 41 further includes a first adapter part 413. The first clamping jaw 411 is arranged on the first mounting seat 412 through the first adapter part 413. The second tie bar clamping component 42 further includes a second adapter part 423. The second clamping jaw 421 is arranged on the second mounting seat 422 through the second adapter part 423.

[0059] Among them, the shape of the first adapter part 413 is not limited, and it is arranged between the first clamping jaw 411 and the first mounting seat 412. In addition, the first clamping jaw 411 can rotate relative to the first mounting seat 412 through the first adapter part 413.

[0060] It can be understood that the setting of the first adapter part 413 strengthens the flexibility of the first clamping jaw 411. Compared with the rigid connection, the setting of the first adapter part 413 increases the movement redundancy of the first clamping jaw 411 to a certain extent and increases the service life of the tie bar installation device. In addition, the setting method of the second adapter part 423 is the same as that of the first adapter part 413. That is to say, the first adapter part 413 and the second adapter part 423 can be bearings.

[0061] In an alternative embodiment, as Figure 3 shown, a welding part 43 is arranged on the side of the first adapter part 413 facing away from the first mounting seat 412. In the case where the first tie bar 51 clamped by the first clamping jaw 411 and the second tie bar 52 clamped by the second clamping jaw 421 are butted, the welding part 43 can weld the first tie bar 51 and the second tie bar 52.

[0062] It should be noted that the installation position of the welding part 43 should ensure that after the first tie bar 51 is clamped, the welding head of the welding part 43 is close to the butting end of the first tie bar 51, and after the second tie bar 52 is butted with the first tie bar 51, the butting part of the first tie bar 51 and the second tie bar 52 can be welded.

[0063] In an alternative embodiment, as Figure 4 As shown, the first tie bar clamping component 41 includes a third jaw 414 and a third mounting seat 415. The third jaw 414 is arranged on the outer periphery of the first-stage telescopic tube 32 through the third mounting seat 415. The second tie bar clamping component 42 includes a fourth jaw 424 and a fourth mounting seat 425. The fourth jaw 424 is arranged on the outer periphery of the second-stage telescopic tube 33 through the fourth mounting seat 425. The first tie bar clamped by the third jaw 414 and the second tie bar clamped by the fourth jaw 424 can be lapped.

[0064] Among them, the first tie bar 51 includes a first straight portion and a first bent portion extending by bending from the first straight portion. The second tie bar 52 includes a second straight portion and a second bent portion extending by bending from the second straight portion. The lapping of the first tie bar 51 and the second tie bar 52 means that the first straight portion and the second straight portion are arranged side by side.

[0065] The shape of the third mounting seat 415 is not limited. For example, it can be an "L" shape, a "U" shape, an "O" shape or a "square" shape, etc. For example, the third mounting seat 415 can be a tubular structure with a round inner and a square outer, and is sleeved on the outer periphery of the first-stage telescopic tube 32. In addition, the third mounting seat 415 is arranged near the second-stage telescopic tube 33 on the first-stage telescopic tube 32 so that the first-stage telescopic tube 32 has the maximum telescopic ability. A third jaw 414 is provided on the side of the third mounting seat 415 facing away from the first-stage telescopic tube 32. The opening and closing of the third jaw 414 can achieve the grasping of the first tie bar 51. [[ID=⑨]]

[0066] In addition, the second tie bar clamping component 42 can have the same structure and installation position as the first tie bar clamping component 41, which will not be elaborated here.

[0067] It should be particularly pointed out that when the first tie bar clamping component 41 and the second tie bar clamping component 42 have the same structure, the grasping axis of the fourth jaw 424 deviates from the grasping axis of the third jaw 414, and the distance between the two axes is exactly equal to the diameter of a tie bar. Thus, when the second-stage telescopic tube 33 approaches the first-stage telescopic tube 32, the first tie bar 51 clamped by the third jaw 414 and the second tie bar 52 clamped by the fourth jaw 424 can be lapped.

[0068] In an optional embodiment, as Figure 4 shown, the first extension length of the third jaw 414 in the direction away from the third mounting seat 415 is less than the second extension length of the fourth jaw 424 in the direction away from the fourth mounting seat 425. [[ID=①⑩]]

[0069] It should be noted that the difference between the lengths of the third clamping jaw 414 and the fourth clamping jaw 424 is exactly equal to the diameter of one tie bar. When the fourth clamping jaw 424 grips the second tie bar 52 and the third clamping jaw 414 grips the first tie bar 51, the distance between the center axis of the second straight portion of the second tie bar 52 and the center axis of the first straight portion of the first tie bar 51 is exactly equal to the diameter of one tie bar. In this case, when the secondary telescopic tube 33 approaches the primary telescopic tube 32, the first tie bar 51 and the second tie bar 52 can achieve an overlapping fit.

[0070] In an optional embodiment, if Figure 4 As shown, the third mounting seat 415 is provided with a first mounting surface 4151 and a side adjacent to the first mounting surface 4151, and the third clamping jaw 414 is provided on the first mounting surface 4151; the fourth mounting seat 425 is provided with a second mounting surface 4251 and a side adjacent to the second mounting surface 4251, and the fourth clamping jaw 424 is provided on the second mounting surface 4251; at least one of the side surfaces of the third mounting seat 415 and the side surfaces of the fourth mounting seat 425 is provided with a welding member 43, and when the first tie bar clamped by the third clamping jaw 414 and the second tie bar clamped by the fourth clamping jaw 424 are overlapped, the welding member 43 can weld the first tie bar and the second tie bar.

[0071] It should be noted that in order to facilitate the welding of the first tie bar 51 and the second tie bar 52 arranged side by side, a welding part 43 is provided on the side adjacent to the first mounting surface 4151; or a welding part 43 is provided on the side adjacent to the second mounting surface 4251; or a welding part 43 is provided on the side adjacent to the first mounting surface 4151 and the side adjacent to the second mounting surface 4251. The welding part 43 can weld the sides of the first tie bar 51 and the second tie bar 52.

[0072] That is to say, when the first tie bar 51 clamped by the third clamping jaw 414 and the second tie bar 52 clamped by the fourth clamping jaw 424 are in overlap, the first tie bar 51 and the second tie bar 52 are welded by one or more welding parts 43 to ensure the stability of the overlap.

[0073] In an optional embodiment, if Figure 4 As shown, in the case where the welding part 43 is provided on the side of the third mounting seat 415, the third mounting seat 415 is provided with two opposite side surfaces, and both sides of the third mounting seat 415 are provided with the welding part 43; and / or, in the case where the welding part 43 is provided on the side of the fourth mounting seat 425, the fourth mounting seat 425 is provided with two opposite side surfaces, and both sides of the fourth mounting seat 425 are provided with the welding part 43.

[0074] For example, welding members 43 are provided on two opposing sides of the third mounting seat 415, and the two welding members 43 on the third mounting seat 415 are symmetrically arranged relative to the third mounting seat 415. Welding members 43 are provided on two opposing sides of the fourth mounting seat 425, and the two welding members 43 on the fourth mounting seat 425 are symmetrically arranged relative to the fourth mounting seat 425. This allows four-point fixed welding to be achieved on two opposing sides of the overlapped joint of the first and second tie bars 51, 52, thereby fully ensuring the stability of the overlapped joint of the first and second tie bars 51, 52 and improving welding efficiency.

[0075] In an optional embodiment, if Figures 5 to 7 As shown, the bracket 1 includes a column 11 and a crossbeam 12. The crossbeam 12 is provided with a guide portion 121 extending along its length. The running mechanism 2 includes a snap-fit ​​portion 21 adapted to the guide portion 121. The snap-fit ​​portion 21 is slidably connected to the guide portion 121. The snap-fit ​​portion 21 is provided on the side of the running mechanism 2 facing the crossbeam 12.

[0076] Among them, the column 11 has various forms and materials. For example, two "I"-shaped steels of exactly the same shape and size can be used and respectively arranged on both sides of the beam 12 to improve the stability of the support. The bottom side of the beam 12 is provided with a guide portion 121 extending along its length direction. The shape of the guide portion 121 is not limited, for example, an inverted V shape, a U shape, etc.

[0077] In an embodiment of the present invention, through the sliding cooperation between the guide part 121 and the buckling part 21, the walking mechanism 2 can move relative to the length direction of the beam 12, so that the walking mechanism 2 can drive the first tie bar clamping assembly 41 and the second tie bar clamping assembly 42 to move to the target position.

[0078] It should be noted that the bottom of the column 11 can be provided with a moving wheel to enable free movement. In addition, to ensure the stability of the structure, the crossbeam 12 and the column 11 can be connected in an integrated manner, such as by welding, riveting, etc.

[0079] In the embodiment of the present invention, the first tie bar 51 and the second tie bar 52 may be welded in an overlapping or / and butt-jointed manner. Here, the first tie bar 51 and the second tie bar 52 are welded in a butt-jointed manner for illustration.

[0080] In an optional embodiment, if Figures 8 to 12 As shown, the installation method of the tie bar installation device for a steel bar skeleton of the present invention includes:

[0081] S100, the first telescopic tube 32 moves relative to the cylindrical shell 31 so that the first tie bar 51 clamped by the first tie bar clamping assembly 41 is located above the upper tie bar connection point 61, and the second telescopic tube 33 moves relative to the first telescopic tube 32 so that the second tie bar 52 clamped by the second tie bar clamping assembly 42 is located below the lower tie bar connection point 62.

[0082] Specifically, through the sliding cooperation between the guide part 121 and the buckling part 21, the first clamp clamps the first tie bar 51, and the second clamp clamps the second tie bar 52. Through the sliding cooperation between the guide part 121 and the buckling part 21 again, the buckling part 21 moves to the corresponding position where the tie bar needs to be installed on the steel skeleton; the first-level telescopic tube 32 moves downward relative to the cylindrical shell 31, so that the first tie bar 51 clamped by the first clamp is located above the upper tie bar tie point 61, and the second-level telescopic tube 33 moves downward relative to the first-level telescopic tube 32, so that the second tie bar 52 clamped by the second clamp is located below the lower tie bar tie point 62.

[0083] In order to facilitate the expansion and contraction of the primary telescopic tube 32 and the secondary telescopic tube 33 , the first tie bars 51 and the second tie bars 52 correspond to the gaps in the steel skeleton.

[0084] S200 , driven by the rotating mechanism, the first tie bar 51 , the upper tie bar connection point 61 , the second tie bar 52 and the lower tie bar connection point 62 are aligned in a collinear manner.

[0085] In other words, the guide rail portion on the circumferential side of the top of the cylindrical shell 31 rotates relative to the annular groove at the bottom of the walking mechanism 2 to adjust the positions of the first tie bar 51 and the second tie bar 52. At this time, the first tie bar 51 is located directly above the upper tie bar tie point 61, and the second tie bar 52 is located directly below the lower tie bar tie point 62.

[0086] S300, the first telescopic tube 32 moves again relative to the cylindrical shell 31 so that the first tie bar 51 clamped by the first tie bar clamping assembly 41 abuts against the upper tie bar tie point 61, and the second telescopic tube 33 moves again relative to the first telescopic tube 32 so that the second tie bar 52 clamped by the second tie bar clamping assembly 42 abuts against the lower tie bar tie point 62.

[0087] Specifically, the first telescopic tube 32 moves downward relative to the cylindrical shell 31 until the first tie bar 51 abuts against the upper tie bar tie point 61, and the second telescopic tube 33 moves upward relative to the first telescopic tube 32 until the second tie bar 52 abuts against the lower tie bar tie point 62.

[0088] It should be noted that the end of the tie bar that contacts the tie bar connection point is in the shape of a hook, and its angle is determined by the actual situation. When the tie bar contacts the tie bar connection point, the hook is just stuck on the tie bar connection point.

[0089] S400 , welding the first tie bar 51 and the second tie bar 52 through the welding member 43 .

[0090] Specifically, when the first tie bar 51 and the second tie bar 52 are butted together, the butting point is welded by the welding piece 43 .

[0091] Repeat the above steps S100 to S400 to complete the welding of the entire steel bar skeleton and the tie bars.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
