Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, the utility model provides a tunnel arch center connecting plate welding positioning auxiliary, which is described sequentially from front to back, and comprises a positioning rod 1, a front plate 2, an angle steel section 3, a handle 4, a back plate 5, wherein the front plate 2 and the back plate 5 are square plate bodies with the same size, the front plate 2 and the back plate 5 are arranged in parallel, the angle steel section 3 is clamped between the front plate 2 and the back plate 5, the angle steel section 3 is arranged in the middle, the opening of the angle steel section 3 is upward, and the arc-shaped handle 4 is arranged in the angle steel section 3.
The two positioning rods 1 are vertically and outwards arranged on the front plate 2, and the two positioning rods 1 are arranged at the same height.
The locating lever is the awl body of rod, including guide section and back end, and guide section diameter is less than the back end diameter, and the diameter increases gradually, and the external diameter to its back end and front bezel junction equals connecting hole 8 internal diameters on connecting plate 7, and preferred connected mode is to pass the front bezel with the locating lever to it is fixed to weld or rubber coating in front bezel inside.
The diameter of guide section is less than the diameter of connecting hole 8 on the connecting plate 7, and its terminal external diameter equals the internal diameter of connecting hole 8 on the connecting plate 7, the aim at of design like this: the diameter of the pilot section of the positioning rod is smaller than the designed diameter of the bolt hole, so that the pilot section can smoothly pass through the bolt hole of the connecting plate and can be accurately positioned and controlled; the diameter of the rear section of the positioning rod is gradually consistent with the design diameter of the bolt hole, so that a gap between the bolt and the bolt hole is eliminated, the welding of the connecting plate and the end of the I-shaped steel is centered, and the position of the bolt hole is more accurate.
