[0043] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0044] During the shipbuilding process, steel pipe scaffolding is often set up according to production needs during the stages of block production, slipway construction, and dock installation and commissioning. When setting up steel pipe scaffolding, some "T-shaped" structures require the use of clamping fixtures that can clamp such structures, and then set up steel pipe scaffolding on the support rods of the clamping fixtures. However, due to the limitations of on-site installation conditions, the erection angle conditions of the steel pipe scaffolding in some locations are limited, resulting in the tilt of the gangway, which poses certain hidden dangers to subsequent construction safety.

[0045] After the chuck fixture is clamped and fixed on the "T-shaped" structure, in order to ensure that the erected scaffolding keeps the springboard level, the support rod of the chuck fixture needs to be able to rotate according to the actual situation on site, and the chuck fixture needs to be adjusted to the required shape and then locked and fixed. However, such chuck fixture is not available on site at present.

[0046] To this end, the present application proposes a T-shaped chuck fixture 100 with an adjustable angle for use in erecting scaffolding to solve the above-mentioned problem.

[0047] Reference below Figure 1-Figure 7 A chuck fixture 100 with a T-shaped structure according to an embodiment of the present application is described.

[0048] In this embodiment, the chuck fixture 100 includes a mounting plate 1 , two clamping mechanisms 2 , a guide plate 3 and a support rod 4 .

[0049] The mounting plate 1 has a first side and a second side opposite to each other in a thickness direction, and is used to support the clamping mechanism 2 , the guide plate 3 and the support rod 4 .

[0050] The two clamping mechanisms 2 are movably mounted on the first side of the mounting plate 1, and the two clamping mechanisms 2 are respectively used to clamp the two side edges of the T-shaped structure. The clamping mechanism 2 is movably arranged on the first side of the mounting plate 1, so that the clamping mechanism 2 can perform clamping operations. It can be understood that the two side edges of the T-shaped structure are the side edges extending to both sides of the T-shaped structure. The two side edges of the T-shaped structure are respectively clamped by the two clamping mechanisms 2, so that the first side of the mounting plate 1 is fixed to the T-shaped structure, thereby realizing the fixation of the chuck fixture 100 on the T-shaped structure.

[0051] The guide plate 3 is fixedly installed on the second side of the mounting plate 1 and is perpendicular to the mounting plate 1. The guide plate 3 is provided with a plurality of positioning portions distributed along its circumference; the support rod 4 is rotatably installed on the guide plate 3 around an axis extending radially thereof, and the axis is perpendicular to the guide plate 3. The support rod 4 is provided with a connecting portion that can be matched with any positioning portion.

[0052] The guide plate 3 serves to connect and support the support rod 4. The guide plate 3 and the support rod 4 are installed on the second side of the mounting plate 1 to facilitate the connection between the steel pipe scaffold and the support rod 4. The guide plate 3 is fixed vertically to the mounting plate 1. For example, one end of the guide plate 3 in the height direction can be fixedly installed on the mounting plate 1 by welding to ensure the structural strength of the guide plate 3. The support rod 4 is rotatably installed on the guide plate 3 around an axis extending along its radial direction, and the axis is perpendicular to the guide plate 3, so that the support rod 4 can change the angle between the support rod 4 and the mounting plate 1 when rotating, so as to facilitate the adjustment of the angle of the steel pipe connected to the support rod 4. By providing a plurality of positioning parts distributed along the circumference of the guide plate 3 on the guide plate 3, the support rod 4 can correspond to the positioning parts at different positions on the guide plate 3 during the rotation process. The support rod 4 is provided with a connecting part that can be matched with any positioning part. By matching the connecting part with the corresponding positioning part, the support rod 4 is fixed, providing support force for the steel pipe scaffold.

[0053] In actual implementation, the two clamping mechanisms 2 are first clamped on the two sides of the T-shaped structure to fix the clamping tooling on the T-shaped structure, and the relative angle between the support rod 4 and the mounting plate 1 is adjusted by rotation as required. When adjusted to a suitable angle, the connecting portion on the support rod 4 corresponds to one of the multiple positioning portions, and the support rod 4 is fixed by matching and connecting the connecting portion with the corresponding positioning portion, and then the subsequent steel pipe scaffolding installation is carried out.

[0054] According to the clamping fixture of the T-shaped structure provided in the embodiment of the present application, the clamping fixture 100 is fixed by setting up two clamping mechanisms 2 to clamp the two sides of the T-shaped structure. By setting up the guide plate 3 and the support rod 4, the inclination angle of the support rod 4 is adjusted by rotating the support rod 4 when erecting the steel pipe scaffolding. When adjusted to a suitable angle, the support rod 4 is fixed by connecting the connecting part with the positioning part, thereby meeting the structural strength of the supporting steel pipe scaffolding and being able to adjust the angle of the steel pipe to keep the springboard level. It is easy to use and improves construction safety.

[0055] In the examples of this application, refer to Figure 1-Figure 3 In order to make the overall structure evenly stressed, when the support rod 4 is rotated to be perpendicular to the mounting plate 1, the projection of the axis of the support rod 4 on the mounting plate 1 is the geometric center of the mounting plate 1 in the thickness direction.

[0056] According to some embodiments of the present application, Figure 1-Figure 4 As shown, especially Figure 4 The guide plate 3 may be provided with a mounting hole 32 penetrating along the thickness direction thereof, and the end of the support rod 4 close to the mounting plate 1 may be rotatably mounted on the mounting hole 32 by a first bolt 5, and a plurality of positioning portions may be arranged around the mounting hole 32 with the mounting hole 32 as the center.

[0057] In this embodiment, the guide plate 3 may be provided with a mounting hole 32, and the end of the support rod 4 close to the mounting plate 1 may be rotatably connected to the guide plate 3 by a first bolt 5 passing through the mounting hole 32, and a first nut 51 is threadedly connected to the first bolt 5, so that the support rod 4 is connected to the guide plate 3, and the end of the support rod 4 away from the mounting plate 1 is a free end, which can be rotatably arranged around the axis passing through the mounting hole 32. Exemplarily, the end of the support rod 4 close to the mounting plate 1 may be provided with a through hole 451 passing through along the axial direction, and the first bolt 5 passes through the mounting hole 32 and the through hole 451 to achieve a mating connection. Alternatively, in another example, the first bolt 5 may be integrated at the end of the support rod 4 close to the mounting plate 1.

[0058] It can be understood that the connection part is arranged in the middle of the support rod 4, and multiple positioning parts are arranged around the mounting hole 32 with the mounting hole 32 as the center, that is, the spacing between each positioning part and the axis of the mounting hole 32 is the same, and the connection part moves in an arc when the support rod 4 rotates around the axis. By setting multiple mounting parts around the mounting hole 32, the connection part and the positioning part can be matched accordingly. In order to improve the stability of the overall structure, the mounting hole 32 can be arranged in the center in the length direction of the guide plate 3.

[0059] The mounting hole 32 is arranged at a certain distance from the mounting plate 1 to facilitate the rotation of the end of the support rod 4 and avoid interference between the support rod 4 and the mounting plate 1 .

[0060] In this embodiment, because the support rod 4 extends in a direction away from the mounting plate 1 , at least part of the plurality of positioning portions are disposed on a side of the mounting hole 32 away from the mounting plate 1 , so as to facilitate the matching connection between the positioning portions and the connecting portions.

[0061] In one example, if Figure 1 and Figure 4 As shown, a plurality of positioning portions are arranged in a semicircle around the mounting hole 32, and the lines connecting the positioning portions at both ends and the axis of the mounting hole 32 are arranged parallel to the mounting plate 1, thereby limiting the rotation angle range of the support rod 4 to 180°, so as to avoid the support rod 4 rotating to a negative angle and interfering with the mounting plate 1, which is not conducive to installation and load.

[0062] In other embodiments, the connecting portion can be provided at one end of the support rod 4 close to the mounting plate 1, the middle portion of the support rod 4 is rotatably connected to the mounting hole 32, at least part of the positioning portion is provided on the side of the mounting hole 32 close to the mounting plate 1, and the end of the support rod 4 away from the mounting plate 1 is a free end. This example can also realize the rotation and fixation of the support rod 4.

[0063] In some other embodiments, the spacing between each positioning portion and the mounting hole 32 can be irregularly set to improve the structural strength of the guide plate 3. The connecting portion on the support rod 4 is provided with multiple connecting positions distributed along the length direction of the support rod 4, so that the multiple connecting positions correspond to the positioning portions with different spacing distances. When it is rotated to a suitable angle, the connecting positions at corresponding positions can be matched with the corresponding positioning portions for connection.

[0064] In some embodiments, Figure 1 and Figure 4 As shown, the guide plate 3 may be arranged in a fan shape, and the side of the guide plate 3 away from the mounting plate 1 may be arranged in an arc shape, so that the lengths of the support rods 4 extending out of the guide plate 3 are the same.

[0065] In other embodiments, the guide plate 3 may also be arranged in a square or polygonal shape, which is not specifically limited here.

[0066] According to some embodiments of the present application, Figure 1 and Figure 4 As shown, the positioning portion may include a positioning hole 31, which may be arranged through the guide plate 3 along the thickness direction of the guide plate 3, and the connecting portion may include a connecting hole 43, which is arranged through the support rod 4 along the thickness direction of the guide plate 3, and the connecting portion and the positioning portion are connected by a second bolt 6 that passes through the positioning hole 31 and the connecting hole 43.

[0067] In this embodiment, the positioning portion may include a positioning hole 31 passing through the guide plate 3, and the connecting portion may include a connecting hole 43 passing through the support rod 4. By setting a second bolt 6 passing through the positioning hole 31 and the connecting hole 43, and by connecting a second nut 61 threadably matched with the second bolt 6, the support rod 4 is fixedly connected to the guide plate 3.

[0068] In actual implementation, the second bolt 6 is pulled out when the support rod 4 is rotated. When the support rod 4 is rotated to a suitable angle, the connecting hole 43 corresponds to a positioning hole 31. The second bolt 6 is passed through the mounting hole 32 and the connecting hole 43, and then tightened by the second nut 61 to achieve a fixed connection.

[0069] In other embodiments, the positioning portion may further include a positioning groove, which is provided on one side of the guide plate 3 close to the support rod 4. The connecting portion may include an elastic telescopic member provided on the support rod 4. The elastic telescopic member can be elastically telescopically arranged along the extension direction of the axis. When the support rod 4 is rotated, the elastic telescopic member is controlled to shrink into the support rod 4. When the support rod 4 is rotated to a suitable angle, the elastic telescopic member is released, and the elastic telescopic member pops up and extends into the corresponding positioning groove to achieve a mating connection. The driving mode of the elastic telescopic member is not limited again. It can be pressed by setting a connecting rod structure connected thereto, or it can be extruded by a knob, or it can be other commonly used driving structures on the market.

[0070] According to some embodiments of the present application, Figure 1 , Figure 2 and Figure 5 As shown, the support rod 4 may include a round tube 41 , a pad 44 and a rotating plate 45 .

[0071] The round tube 41 may be a round steel tube, which has high structural strength and is easy to cooperate with a steel tube scaffold. The connecting hole 43 is provided on the round tube 41 .

[0072] The pad 44 can be covered on one end of the circular tube 41 close to the mounting plate 1, and the rotating plate 45 is arranged on the side of the pad 44 away from the circular tube 41. A through hole 451 is provided on the rotating plate 45. The rotating plate 45 can be rotatably mounted on the guide plate 3 through a first bolt 5 that penetrates the mounting hole 32 and the through hole 451.

[0073] In this embodiment, a pad 44 is provided to close one end of the circular tube 41 close to the mounting plate 1 for easy connection, and the rotating plate 45 can be welded to the pad 44, and the rotating plate 45 can be perpendicular to the pad 44, and the pad 44 is parallel to the guide plate 3, and the through hole 451 on the pad 44 is coaxial with the axis, so that the first bolt 5 can pass through the mounting hole 32 and the through hole 451, thereby realizing the rotational connection of the support rod 4 on the guide plate 3, and the durability and structural strength of the support rod 4 are improved by providing the rotating plate 45.

[0074] In one example, a side of the rotating plate 45 close to the mounting plate 1 is arranged in an arc shape, so that interference between the rotating plate 45 and the mounting plate 1 is not likely to occur during the rotation of the support rod 4 .

[0075] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the support rod 4 may further include a sealing plate 46, which is covered at one end of the circular tube 41 away from the mounting plate 1 to prevent debris from falling into the circular tube 41 during the construction process.

[0076] According to some embodiments of the present application, Figure 1 , Figure 2 and Figure 5 As shown, the support rod 4 may further include a sleeve 42 , the sleeve 42 is sleeved outside the round tube 41 , and the connecting hole 43 is provided through the sleeve 42 and the round tube 41 .

[0077] In this embodiment, the support rod 4 also includes a sleeve 42, which is arranged at the connecting portion of the support rod 4, so that the sleeve 42 is sleeved outside the round tube 41 and welded to the round tube 41 to improve the structural strength of the round tube 41 at the corresponding position. The connecting hole 43 is set through the sleeve 42 and the round tube 41, so that when the second bolt 6 connects the support rod 4 and the guide plate 3, the support rod 4 is not easy to be deformed and damaged, thereby improving the structural strength and safety performance.

[0078] According to some embodiments of the present application, Figure 2 and Figure 3 As shown, two guide plates 3 can be provided, and the two guide plates 3 can be spaced apart along the thickness direction thereof, and the multiple positioning portions of the two guide plates 3 correspond one to one along the thickness direction of the guide plates 3, and the support rod 4 can be rotatably installed between the two guide plates 3 by means of a first bolt 5, and the connecting portion can be matched and connected with any pair of the two positioning portions.

[0079] It can be understood that the two guide plates 3 have the same structure and are arranged parallel to each other, so that the multiple positioning parts on the two guide plates 3 correspond to each other one by one, and the connecting part can be connected with any pair of corresponding two positioning parts. By setting two guide plates 3 and arranging the support rod 4 between the two guide plates 3, the supporting strength of the support rod 4 and the strength and stability of the overall structure can be improved.

[0080] Among them, the rotation connection of the support rod 4 can be achieved by passing through the mounting holes 32 of the two guide plates 3 and the through hole 451 of the support rod 4, and the support rod 4 can be fixed by passing through the positioning holes 31 of the two guide plates 3 and the connecting hole 43 of the support rod 4 by the second bolt 6.

[0081] According to some embodiments of the present application, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the clamping mechanism 2 may include a first clamping plate 21 , a second clamping plate 22 and a connecting plate 23 .

[0082] The first clamping plate 21 can be parallel to the mounting plate 1 and can be movably installed on the first side of the mounting plate 1. The first clamping plate 21 is arranged on the first side of the mounting plate 1 so that it is not easy to interfere with the guide plate 3, the support rod 4 and other components when the first clamping plate 21 moves. By setting the first clamping plate 21 movably, the clamping mechanism 2 can be driven to change its relative position on the mounting plate 1, so as to facilitate the clamping work.

[0083] The second clamping plate 22 can be parallel to the first clamping plate 21 and is arranged on the side of the first clamping plate 21 away from the mounting plate 1. The second clamping plate 22 is provided with a threaded hole 222 penetrating along its thickness direction and a clamping bolt 221 movably installed in the threaded hole 222. The connecting plate 23 can be connected to one side of the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 are spaced apart in the thickness direction so that the first clamping plate 21, the second clamping plate 22 and the connecting plate 23 define a clamping space for clamping the side of the T-shaped structure.

[0084] In this embodiment, the second clamping plate 22 is parallel to the first clamping plate 21 and is spaced apart from the first clamping plate 21 along the reverse thickness direction. The second clamping plate 22 is arranged on the side of the first clamping plate 21 away from the mounting plate 1, and is welded and connected to the same side of the first clamping plate 21 and the second clamping plate 22 by the connecting plate 23, so that the first clamping plate 21, the second clamping plate 22 and the connecting plate 23 form a whole, and the first clamping plate 21, the second clamping plate 22 and the connecting plate 23 define a clamping space for clamping the side of the T-shaped structure. It can be understood that the nut of the clamping bolt 221 is located on the side of the second clamping plate 22 away from the first clamping plate 21, and the free end of the clamping bolt 221 is located in the clamping space.

[0085] Among them, the clamping spaces of the two clamping mechanisms 2 are relatively arranged, and the two clamping mechanisms 2 can be movably arranged in directions approaching and moving away from each other. By setting the two clamping spaces relatively, the two clamping mechanisms 2 can respectively clamp the two sides of the T-shaped structure extending in opposite directions. By controlling the two clamping mechanisms 2 to move in directions approaching and moving away from each other, the sides of the T-shaped structure can enter the clamping space.

[0086] In actual implementation, the two clamping mechanisms 2 are first moved in a direction away from each other to increase the distance between the two clamping mechanisms 2, and the mounting plate 1 is placed on the surface of the T-shaped structure so that the two side edges of the T-shaped structure are respectively opposite to the clamping spaces of the two clamping mechanisms 2, and the two clamping mechanisms 2 are moved in a direction close to each other so that the side edges of the T-shaped structure enter the corresponding clamping spaces, so that the first clamping plate 21 and the second clamping plate 22 of a clamping mechanism 2 are respectively located on both sides of a side edge of the T-shaped structure in the thickness direction, and the side edge of the T-shaped structure is clamped and fixed by the clamping mechanism 2 by rotating the clamping bolt 221 so that the free end of the clamping bolt 221 presses the side edge of the T-shaped structure against the first clamping plate 21. The clamping structure is simple and easy to operate, has high structural strength, and is highly practical, and can be adapted to T-shaped structures of various sizes.

[0087] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the mounting plate 1 may be provided with a plurality of guide grooves 11 extending along the movable direction of the clamping mechanism 2, the guide grooves 11 may be arranged through the mounting plate 1 along the thickness direction of the mounting plate 1, a first clamping plate 21 may be provided with a stud 211 passing through the corresponding guide groove 11 on one side close to the mounting plate 1, the stud 211 may be movably arranged along the extension direction of the guide groove 11, and a fastening nut 212 threadably matched with the stud 211 may be provided on the second side of the mounting plate 1.

[0088] In this embodiment, a plurality of guide grooves 11 are provided on the mounting plate 1, and a stud 211 may be provided on the side of the first clamping plate 21 close to the mounting plate 1. One end of the stud 211 is welded to the first clamping plate 21, and the other end is provided through the guide groove 11 to the first side of the mounting plate 1. A fastening nut 212 that can be threadedly matched with the stud 211 is provided on the second side of the mounting plate 1, so that the first clamping plate 21 is connected to the mounting plate 1 and will not fall off, which is convenient for transportation.
