Description

Technical Field

[0001] The present application relates to the technical field of tunnel welding equipment, and in particular to a device for quickly connecting a straight threaded sleeve. Background Art

[0002] In the construction structure of subway station tunnels, the side walls and inner support beams each have different structural functions. The side wall is one of the main structures of the subway station tunnel, usually made of reinforced concrete, and bears the pressure of the soil layer above the tunnel and other loads. During the excavation of tunnels or underground projects, the inner support beams serve as temporary structures that can be used to support the excavation surface, share the load of the side walls and other structural parts, reduce the burden on the side walls, improve the overall stability of the structure, prevent the surrounding soil or rock from collapsing due to loss of support, and maintain its stability. On the other hand, the inner support beams can also be used as part of the construction platform to provide a safe working space for construction workers.

[0003] During the construction of subway station tunnels, the side walls and inner support beams are usually connected to enhance the stability of the overall structure. A common structure is to set embedded steel bars with external threads at the ends before pouring the side walls, and make the ends of the embedded steel bars exposed outside the side walls. A sleeve is installed at the ends of the embedded steel bars through a threaded connection. After the sleeve is welded and fixed, a steel bar foundation for building the inner support beam is installed at the other end of the sleeve. In order to ensure the stability of the sleeve, it is usually necessary to perform a circle of welding along a circular trajectory at the connection of the sleeve. However, the current welding work of the sleeve still requires the staff to hold the welding gun and aim at the connection of the sleeve for welding. During the welding process, the staff needs to frequently change their postures for welding, which affects work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-3 This application is described in further detail.

[0037] The embodiment of the present application discloses a device for quickly connecting a straight thread sleeve.

[0038] Reference Figure 1 and Figure 2 A device for quickly connecting a straight threaded sleeve comprises a connecting body 1, a sleeve clamp 2, a pusher 11, a rotating rod 3 and a welding assembly. The connecting body 1 is cylindrical, the number of the sleeve clamps 2 is four, the sleeve clamp 2 is used to clamp the sleeve, the sleeve clamp 2 is slidingly connected to one end of the connecting body 1, the sliding direction of the sleeve clamp 2 is perpendicular to the extension direction of the connecting body 1, the pusher 11 is cylindrical, the central axis of the connecting body 1 of the pusher 11 coincides, the inner side of the pusher 11 is threadedly connected to the outer wall of the connecting body 1, the pusher 11 is used to force the sleeve clamp 2 to move so that the sleeve clamp 2 clamps the sleeve, the rotating rod 3 is rotatably connected to the end of the connecting body 1 away from the sleeve clamp 2, and the extension direction of the rotating axis of the rotating rod 3 is consistent with the extension direction of the connecting body 1.

[0039] During the construction of the subway tunnel, after the sleeve is installed on the embedded steel bar through a threaded connection, when the sleeve needs to be welded, the sleeve clamp 2 can be used to clamp the sleeve. After clamping, the welding assembly is placed close to the connection between the sleeve and the embedded steel bar for welding, and the rotating rod 3 is rotated during welding so that the welding assembly rotates one circle following the rotating rod 3, thereby completing the welding of a circle of circular trajectory for the sleeve, so that the staff does not need to change posture frequently for welding, but only needs to rotate the rotating rod 3 to complete the work, thereby simplifying the welding work and improving the convenience of work and welding efficiency.

[0040] One end of the connecting body 1 away from the rotating rod 3 is slidably connected with a clamping rod 21. There are four clamping rods 21, which are distributed in a circle. Four sleeve clamps 2 are respectively connected to the ends of the four clamping rods 21 away from the connecting body 1. The pushing member 11 is sleeved on the outside of the connecting body 1. The inner wall of the pushing member 11 is provided with an internal thread, and the outer wall of the connecting body 1 is provided with an external thread. The inner wall of the pushing member 11 is threadedly connected with the outer wall of the connecting body 1, and the inner wall of the pushing member 11 abuts against the clamping rod 21. The inner wall of the pushing member 11 away from the rotating rod 3 is provided with a rounded corner, and the rounded part of the inner wall of the pushing member 11 abuts against the inclined outer wall of the clamping rod 21. The extension direction of the clamping rod 21 and the extension direction of the pushing member 11 are inclined to each other.

[0041] When the sleeve needs to be clamped, the four sleeve clamps 2 can be placed around the sleeve, and the pusher 11 can be rotated to move the pusher 11 away from the rotating rod 3, thereby applying pressure to the inclined outer wall of the clamping rod 21, pushing the clamping rod 21 to move, and the sleeve clamps 2 are moved closer to each other, thereby clamping the sleeve, which is simple and convenient.

[0042] A return block 12 is slidably connected to the middle part of the end of the connecting body 1 away from the rotating rod 3. The return block 12 is in the shape of a cylindrical block. The sliding direction of the return block 12 is consistent with the extension direction of the connecting body 1. A groove 14 for the return block 12 to slide is provided at the end of the connecting body 1 away from the rotating rod 3. The sliding direction of the return block 12 is perpendicular to the sliding direction of the clamping rod 21. One end of the return block 12 is located in the groove 14, and an inclined surface is provided at the end of the return block 12 away from the groove 14. A protrusion 211 is provided on the side of the clamping rod 21 close to the return block 12. The inclined surface of the return block 12 can abut against the protrusion 211 of the clamping rod 21. An elastic member 13 is provided at the end of the return block 12 located in the groove 14. The elastic member 13 is a spring, and one end of the elastic member 13 is connected to the groove wall of the groove 14 of the connecting body 1.

[0043] When the sleeve is clamped, the propulsion member 11 forces the clamping rod 21 to approach each other, and the protrusion 211 of the clamping rod 21 applies pressure to the inclined surface of the return block 12, thereby forcing the return block 12 to move and press the return block 12 into the groove 14. The elastic member 13 is in a compressed state. When the rotating rod 3 is rotated in the opposite direction to loosen the sleeve, the elastic member 13 applies a thrust to the return block 12, pushing the return block 12 outward, so that the inclined surface of the return block 12 pushes the protrusion 211 of the clamping rod 21, so that the clamping rods 21 move away from each other.

[0044] Reference Figure 1 and Figure 3 The welding assembly includes a flip arm 4 and a flip welding gun 41. The flip arm 4 is rotatably connected to the rotating rod 3. The rotation axis of the flip arm 4 is perpendicular to the rotation axis of the rotating rod 3. The flip welding gun 41 is connected to the flip arm 4.

[0045] After the sleeve is clamped, the flip arm 4 can be rotated to adjust the position of the flip welding gun 41 to find a suitable welding angle.

[0046] An adjustment plate 31 is provided on the side wall of the rotating rod 3, and the flip arm 4 is rotatably connected to the adjustment plate 31 through a rotating shaft. An arc-shaped hole 32 is opened on the side wall of the adjusting plate 31, and a threaded fixing part 42 is threadedly connected to the side wall of the flip arm 4. The threaded fixing part 42 is a bolt, and the screw part of the threaded fixing part 42 passes through the arc-shaped hole 32. The end of the threaded fixing part 42 away from the adjustment plate 31 is the bolt head, and the end of the threaded fixing part 42 away from the adjustment plate 31 is in contact with the side of the adjustment plate 31 away from the flip arm 4.

[0047] After adjusting the angle position of the rotating flip arm 4, the threaded fixing member 42 can be rotated so that the head of the threaded fixing member 42 is pressed against the side of the adjustment plate 31 away from the flip arm 4, thereby facilitating the rapid fixing of the angle and position of the flip arm 4.

[0048] An adjusting frame 43 is slidably connected to the flip arm 4. The adjusting frame 43 is in an L-shaped frame. The adjusting frame 43 can slide along the extension direction of the flip arm 4. A fixing plate 44 is provided at the end of the flip arm 4 away from the rotating rod 3. An adjusting threaded member 45 is rotatably connected to the side wall of the fixing plate 44. The adjusting threaded member 45 is a screw. A rotating head is fixed to the end of the adjusting threaded member 45 away from the fixing plate 44. The adjusting threaded member 45 is threadedly connected to the adjusting frame 43. The adjusting threaded member 45 passes through the adjusting frame 43. The flip welding gun 41 is installed on the adjusting frame 43.

[0049] After the angle and position of the flip arm 4 are fixed, the adjusting screw 45 can be rotated to slide the adjusting frame 43 to further adjust the position of the flip welding gun 41 .

[0050] One end of the flip arm 4 away from the rotating rod 3 is threadedly connected with an abutment rod 46 , which is a screw rod. The abutment rod 46 is threadedly connected to the fixing plate 44 .

[0051] After adjusting the position of the flip welding gun 41, the abutment rod 46 can be rotated to move the abutment rod 46 and then abut against the wall of the tunnel, so that the flip arm 4 can be supported to a certain extent, thereby improving the welding stability.

[0052] The end of the abutment rod 46 is rotatably connected with a rotating bead 47 . When the abutment rod 46 is moved, the rotating bead 47 can abut against the wall of the tunnel. When the rotating rod 3 is rotated, the rotating bead 47 and the wall slide against each other, reducing the wear of the abutment rod 46 .

[0053] The implementation principle of a device for quickly connecting a straight threaded sleeve in an embodiment of the present application is as follows: during the construction of a subway tunnel, after the sleeve is installed on the embedded steel bar, when the sleeve needs to be welded, the clamping rod 21 can be moved to allow the sleeve clamp 2 to clamp the sleeve, and after clamping, the flip arm 4 is rotated to allow the flip welding gun 41 to approach the connection between the sleeve and the embedded steel bar for welding, and the adjusting threaded member 45 is raised to further adjust the welding position. During welding, the rotating rod 3 is rotated to allow the welding assembly to rotate one circle following the rotating rod 3, thereby completing the welding of a circle of annular trajectory for the sleeve, so that the staff does not need to frequently change their posture for welding, but only needs to rotate the rotating rod 3 to complete the work, thereby simplifying the welding work and thus improving the convenience of work and welding efficiency. When the rotating rod 3 rotates, the abutment rod 46 and the rotating bead 47 can improve the stability of the welding.

[0054] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
