[0040] like Figure 1 , Figure 2 The present embodiment shows an arch frame docking mechanism disclosed in the present invention. By improving the existing arch frame docking mechanism, an arch frame hole positioning structure is integrated into the arch frame docking mechanism, so that the hole alignment operation of the arch frame is fast and simple. Specifically, the arch frame docking mechanism includes a support platform 1, a clamping claw assembly 2 arranged on the support platform 1, a first positioning structure and a second positioning structure. The first positioning structure is used to position the bottom surface of the flange plates at the ends of the two arch frames during the arch frame docking process, and the second positioning structure is used to position the side surfaces of the flange plates at the ends of the two arch frames during the arch frame docking process. In conjunction with the mutual abutment limiting of the flange plates at the ends of the two arch frames, the arch frame docking limiting is realized in three directions, which not only has high hole alignment accuracy, but also makes the hole alignment operation of the arch frame fast and simple. At the same time, it can also effectively reduce the labor intensity of construction personnel and eliminate safety hazards.

[0041] In this embodiment, the end flange plates of the arch frames are all rectangular structures. The arch frame grasped by the clamping claw assembly 2 is defined as the first arch frame 8, and its end flange plate is the first flange plate; the arch frame to be docked in the air is defined as the second arch frame 9, and its end flange plate is the second flange plate.

[0042] In this embodiment, both the first positioning structure and the second positioning structure have multiple implementation modes.

[0043] In the first embodiment, the top plane of the support platform 1 can be directly used as the first positioning structure, and the side panel 3 can be set on the top plane of the support platform 1 as the second positioning structure, while making the side panel 3 parallel to the length direction of the support platform 1 and making the side panel 3 perpendicular to the top plane of the support platform 1.

[0044] When performing the docking operation, first grasp the first arch 8 through the clamp assembly 2, so that the bottom surface of the first flange plate abuts against the top plane of the support platform 1, and the side surface of the first flange plate abuts against the side plate 3. Then operate the arm frame so that a corner point of the second flange plate falls on the top plane of the support platform 1, and then rotate and / or translate the support platform 1 to perform the following three steps:

[0045] 1. Rotate and / or translate the support platform 1 so that the bottom surface of the second flange plate abuts against the top plane of the support platform 1;

[0046] 2. Rotate and / or translate the support platform 1 so that the side surface of the second flange plate abuts against the side plate 3;

[0047] 3. Translate the support platform 1 so that the first flange plate and the second flange plate abut against each other;

[0048] The above three-step operation sequence can be interchanged. After the three-step operation is completed, it indicates that the first arch frame 8 and the second arch frame 9 have completed the hole alignment, and the subsequent bolt assembly operation can be carried out.

[0049] It is worth noting that in the specific application process, the side panel 3 and the supporting platform 1 can also be set to be non-perpendicular, that is, one end of the side panel 3 is connected to the supporting platform 1, and the other end extends away from the supporting platform 1. That is, when positioning the side of the flange plate, the bottom end of the side panel 3 is made to abut the side of the flange plate to achieve the same positioning effect.

[0050] As a preferred solution of the first embodiment, the side panel 3 can be connected to the top plane of the support platform 1 through an assembly structure, so that the side panel 3 has a displacement stroke along the width direction of the support platform 1, so that the arch frame docking mechanism can adapt to the hole positioning of different types of arch frames. In the specific implementation process, a connecting plate can be welded at the bottom of the side panel 3, and a through hole can be opened on the connecting plate, and a strip groove along the width direction of the support platform 1 can be opened on the support platform 1, and then the through hole and the strip groove can be matched by bolts to fix the side panel 3 on the top plane of the support platform 1, and the matching position of the through hole and the strip groove can be manually adjusted to achieve the displacement of the side panel 3. Alternatively, a slide rail or a slide groove along the width direction of the support platform 1 can be set on the support platform 1, and the side panel 3 can be slidably connected to the slide rail or the slide groove, and a cylinder or a screw nut pair can be set on the support platform 1 to drive the side panel 3 to slide, so that the position of the side panel 3 on the top plane of the support platform 1 can be automatically adjusted.

[0051] Further preferably, a second positioning structure may be formed by two side plates 3, and the two side plates 3 are spaced apart on the top plane of the supporting platform 1 to respectively position the side surfaces at both ends of the flange plate at the end of the arch.

[0052] When the two side panels 3 are displaced by the above-mentioned manual adjustment method, the docking process of the first arch frame 8 and the second arch frame 9 is as follows:

[0053] First, adjust the positions of the two side plates 3 on the top plane of the support platform 1 so that the distance between the two side plates 3 is slightly larger than the width of the first flange plate and the second flange plate, for example, 0.5 to 1 cm larger;

[0054] Then, the clamping jaw assembly 2 is driven to grab the first arch 8, and the bottom surface of the first flange plate is abutted against the top plane of the supporting platform 1, and at the same time, the two side surfaces of the first flange plate are respectively matched with the side plates 3 on the corresponding sides;

[0055] Subsequently, the supporting platform 1 is rotated and / or translated to embed the second flange plate between the two side plates 3, and then the above three steps are performed to realize the hole alignment operation of the first arch frame 8 and the second arch frame 9.

[0056] When the two side panels 3 are displaced by the above-mentioned automatic adjustment method, the docking process of the first arch frame 8 and the second arch frame 9 is as follows:

[0057] First, adjust the positions of the two side panels 3 on the top plane of the support platform 1 so that the distance between the two side panels 3 is greater than the width of the first flange plate and the second flange plate, for example, greater than 10 cm;

[0058] Then, the clamping jaw assembly 2 is driven to grab the first arch 8, and the bottom surface of the first flange plate abuts against the top plane of the supporting platform 1;

[0059] Then, the supporting platform 1 is rotated and / or translated so that the second flange plate is embedded between the two side plates 3 and the bottom surface of the second flange plate abuts against the top plane of the supporting platform 1;

[0060] Then, the supporting platform 1 is rotated and / or translated so that the first flange plate and the second flange plate abut against each other;

[0061] Subsequently, the two side plates 3 are driven to move, and the supporting platform 1 is rotated and / or translated, so that the two end side surfaces of the first flange plate and the second flange plate respectively abut against the two side plates 3, that is, the hole alignment operation of the first arch frame 8 and the second arch frame 9 is realized.

[0062] In the second embodiment, the first positioning structure can be set as the bottom plate 4 connected to the top plane of the support platform 1, and the second positioning structure can be set as the side plate 3 connected to the top plane of the support platform 1 or the bottom plate 4. Similarly, the side plate 3 is parallel to the length direction of the support platform 1 and perpendicular to the top plane of the support platform 1. The process of arch docking in this embodiment is the same as that in the first embodiment, so it will not be described in detail in this embodiment.

[0063] As a preferred solution of the second embodiment, the side plate 3 can be connected to the top plane or the bottom plate 4 of the support platform 1 through an assembly structure, so that the side plate 3 has a displacement stroke along the width direction of the support platform 1, so that the arch frame docking mechanism can adapt to the hole positioning of different types of arch frames. Among them, the displacement of the side plate 3 is mainly suitable for the end flange plates of arch frames of different widths, but the heights of the flange plates on different types of arch frames will also be different. Therefore, by replacing the bottom plates 4 of different thicknesses, the bottom edges of the end flange plates of different types of arch frames can all abut against the first positioning structure.

[0064] When the side panel 3 is arranged on the top plane of the supporting platform 1, the side panel 3 can have a displacement stroke along the width direction of the supporting platform 1 on the top plane of the supporting platform 1, and the displacement implementation method and the arch frame docking method are the same as the first embodiment.

[0065] When the side panel 3 is arranged on the bottom plate 4, the side panel 3 can have a displacement stroke on the bottom plate 4 along the width direction of the support platform 1. The method of realizing the displacement and the method of connecting the arch frame are the same as those in the first embodiment. It is only necessary to replace the connecting part with the side panel 3 in the first embodiment from the support platform 1 to the bottom plate 4.

[0066] When the side plates 3 are arranged on the bottom plate 4, the bottom plate 4 can also have a displacement stroke along the width direction of the supporting platform 1 on the top plane of the supporting platform 1, which can also achieve the effect of adapting to different types of arch frames.

[0067] Specifically in this embodiment, the number of bottom plates 4 and side plates 3 are both two and one-to-one corresponding. Specifically, a strip groove 401 parallel to the width direction of the support platform 1 is opened on the bottom plate 4, and a mounting hole 101 corresponding to the strip groove 401 is opened on the top plane of the support platform 1. The bottom plate 4 and the support platform 1 can be installed and fixed by bolting the strip groove 401 and the mounting hole 101. As the position of the strip groove 401 and the mounting hole 101 changes, the relative position of the bottom plate 4 on the support platform 1 also changes, so that the side plate 3 can be displaced on the support platform 1. For example Figure 3 As shown, at this time, the matching position of the strip groove 401 with the mounting hole 101 is the first end of the strip groove 401, and at this time, the distance between the two side plates 3 is opened to the maximum; and Figure 4 The matching position of the middle strip groove 401 with the mounting hole 101 is the second end of the strip groove 401, at which time the distance between the two side plates 3 is minimized; for example Figure 5 As shown, the matching position of the strip groove 401 and the mounting hole 101 is the middle area of ​​the strip groove 401, and the spacing between the two side plates 3 is opened to a moderate size. Preferably, there are multiple strip grooves 401 and mounting holes 101 matching the bottom plate 4 and the mounting plate, and they are spaced and distributed in a direction perpendicular to the strip grooves to improve the stability of the connection between the bottom plate 4 and the support platform 1.

[0068] It is worth noting that in the specific application process, it is not limited to using the structure shown in the figure to realize the displacement of the base plate 4 on the support platform 1. The base plate 4 and the support platform 1 can also be set to have a clearance fit or a slide groove and slider fit, and then a driving cylinder is hinged on the support platform 1, so that the other end of the driving cylinder is hinged to the base plate 4 or the side plate 3, so that the displacement of the base plate 4 can also be realized by the extension and retraction of the driving cylinder.

[0069] In addition, in the specific application process, the second positioning structure is not limited to a plate-shaped structure, and a limit rod parallel to the length of the supporting platform 1 can also be directly used to achieve the corresponding lateral positioning effect.

[0070] As a preferred embodiment, a stopper 7 is further welded on the inner wall of the side plate 3 for abutting against the first flange plate to complete the initial positioning of the first flange plate.

[0071] As a preferred embodiment, the arch docking mechanism also includes a first expansion plate 5 and a second expansion plate 6, wherein the first end of the first expansion plate 5 is connected to the top of the side plate 3, and the second end of the first expansion plate 5 is deflected along the width direction of the support platform 1 in a direction away from the support platform 1 to form a first trumpet-shaped structure. The first end of the second expansion plate 6 is connected to a side end of the side plate 3 away from the support platform 1, and the second end of the second expansion plate 6 is deflected along the width direction of the support platform 1 in a direction away from the support platform 1 to form a second trumpet-shaped structure. By designing the first trumpet-shaped structure and the second trumpet-shaped structure, when the number of side plates 3 is two, it is easier for the flange plate to fall between the two side plates 3, thereby achieving the purpose of rapid hole installation. Among them, the first expansion plate 5 and the second expansion plate 6 can be either integrally formed with the side plate 3 or fixedly connected to the side plate 3 by welding.

[0072] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
