Technical Field

[0001] The utility model belongs to the technical field of steel structure processing, and specifically relates to a marking and positioning device for steel structures. Background Art

[0002] Marking and positioning of steel structures refers to marking the locations where cutting, welding, drilling, etc. are required on the surface of steel materials by marking during the processing, installation or construction of steel structures, so as to accurately carry out subsequent processes. The accuracy of marking and positioning directly affects the processing quality and installation accuracy of steel structures.

[0003] Many existing methods for marking and locating steel structures use a ruler and a marker pen for marking. Although the positioning effect can be achieved, the ruler is usually used by hand, which has a certain accuracy error. In addition, some steel structures are erected at high places. When positioning and marking them, on-site operations are relatively dangerous. It is inconvenient for operators to hold a ruler and a marker pen at high places, which reduces the accuracy of the marking information. Utility Model Content

[0004] The purpose of the utility model is to provide a marking and positioning device for steel structures, which can be placed or clamped according to the position of the steel structure, so as to facilitate marking and positioning of the steel structure at different positions.

[0007] The clamping assembly includes a connecting plate, which is U-shaped. A top plate is arranged on the inner side of the connecting plate. A screw is threadedly connected to the bottom surface of the connecting plate. One end of the screw is rotatably connected to the top plate. Screw holes are respectively provided on the counterweight block and the top surface of the connecting plate, and the bottom end of the vertical rod is adapted to the screw hole.

[0008] The elastic component comprises a spring fixedly connected to the side wall of the placement hole, and the other end of the spring is fixedly connected to a baffle.

[0009] The side wall of the mounting block is fixedly connected with a T-shaped block, the side wall of the horizontal plate is provided with a T-shaped slot, and the T-shaped block is slidably connected with the T-shaped slot.

[0011] The side wall of the vertical rod is provided with a limiting groove, and the rotating wheel is adapted to the limiting groove.

[0012] The technical effects achieved by this utility model are:

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-Figure 5As shown, a marking and positioning device for steel structures includes a counterweight block 1 and a clamping assembly, the top surface of the counterweight block 1 is equipped with a vertical rod 2, the side wall of the vertical rod 2 is slidably connected to a sleeve 3, the side wall of the sleeve 3 is threadedly connected to a rotating wheel 4, the rotating wheel 4 is against the side wall of the vertical rod 2, the side wall of the sleeve 3 is fixedly connected to a horizontal plate 5, the side wall of the horizontal plate 5 is slidably connected to a mounting block 6, the side wall and the bottom surface of the mounting block 6 are respectively provided with placement holes 7, the side wall and the bottom surface of the mounting block 6 are threadedly connected to the placement holes 7, and an elastic component is arranged in the placement hole 7.

[0023] like Figure 4 As shown, the clamping assembly includes a connecting plate 15, which is U-shaped. A top plate 17 is provided on the inner side of the connecting plate 15. A screw 18 is threadedly connected to the bottom surface of the connecting plate 15. One end of the screw 18 is rotatably connected to the top plate 17. Screw holes 16 are respectively provided on the top surfaces of the counterweight block 1 and the connecting plate 15, and the bottom end of the vertical rod 2 is adapted to the screw hole 16.

[0024] Among them, the clamping assembly is mainly used as a backup structure of the device and is selectively used according to the actual situation on site. It has a simple structure, convenient operation and good stability. It can expand the scope of use of this solution and increase its practicality in marking and positioning of steel structures.

[0025] like Figure 5 As shown, the elastic component includes a spring 9 fixedly connected to the side wall of the placement hole 7, and the other end of the spring 9 is fixedly connected to a baffle 10.

[0026] Specifically, in addition to the marker pen, other markable components such as chalk can also be placed in the placement hole 7, and the elastic component is mainly used for the use of consumable components such as chalk, so as to push the chalk to the front end, which is convenient for marking on the steel structure.

[0027] like Figure 3 As shown, a T-shaped block 11 is fixedly connected to the side wall of the mounting block 6 , a T-shaped slot 12 is provided on the side wall of the transverse plate 5 , and the T-shaped block 11 is slidably connected to the T-shaped slot 12 .

[0028] A pull rod 14 is fixedly connected to the top surface of the T-shaped block 11 , a through slot 13 is formed on the top surface of the transverse plate 5 , and the pull rod 14 passes through the through slot 13 .

[0029] Specifically, the present solution requires setting scales on the side walls of the vertical bar 2 and the horizontal plate 5, respectively, to facilitate dimension measurement during the marking process and to prevent problems such as marking position offset and inaccuracy. The use of a scale can avoid such problems. In addition, since setting a scale is more common in marking positioning facilities, it is not described in detail in the present solution and the accompanying drawings.

[0030] like Figure 1As shown, the side wall of the vertical rod 2 is provided with a limit groove 19, and the rotating wheel 4 is adapted to the limit groove 19. By setting the limit groove 19, the range of movement of the sleeve 3 can be limited, so that it can move in a stable state; secondly, the number of limit grooves 19 can be provided in a plurality, which are distributed in a circular array around the vertical rod 2, and can adapt to the marking work at different angles. During operation, it is only necessary to rotate the rotating wheel 4 to push out the current limit groove 19, and then rotate the sleeve 3 to insert it into the specified limit groove 19.

[0031] The working principle of the utility model is: firstly, the use method is selected according to the on-site requirements, and then the marker is inserted into the placement hole 7, and the bolt 8 is tightened to fix the marker. When it is necessary to position the steel structure at a high place, the vertical rod 2 can be directly screwed into the screw hole 16 on the clamping assembly, and then the screw 18 is rotated to drive the top plate 17 to move, so that the top plate 17 can be tightly pressed against the high supporting structure, and then the marking position can be adjusted according to the requirements. The sleeve 3 can be loosened by rotating the rotating wheel 4. After adjusting the horizontal plate 5 to the specified position through the sleeve 3, the pull rod 14 can be pulled to drive the installation block 6 to move, and the installation block 6 drives the marker to mark the steel structure, so as to achieve the purpose of positioning and marking.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
