Description

Technical Field

[0001] The utility model relates to the technical field of steel box arch bridge manufacturing, in particular to an arch-beam combined section port detection device. Background Art

[0002] The manufacturing technology of steel box arch bridge is an important technology in bridge engineering, especially the manufacturing quality of the joint between the arch rib and the steel box girder (referred to as the arch-beam joint section) is more critical. The characteristics of this arch-beam joint section are that the arch rib and the steel box girder are separate independent structures, and the manufacturing precision is high, especially the dimensional precision control of the contact surface between the arch rib and the steel box girder. Since there is no relevant experience to learn from, if the end face dimensional precision of this arch-beam joint section is not controlled in advance, it will be directly related to the relative position of the stiffening rib inside the steel box girder, affecting the overall stress of the structure.

[0003] The existing technology mainly uses conventional detection methods to detect the end faces of the arch-beam joint section. Usually, after the beam section is assembled, the inspectors use a steel tape measure to measure. This method has the following defects: 1. The end face of the beam section has a special shape, which makes it difficult to measure manually with a steel tape measure; 2. Manual measurement with a steel tape measure is easily affected by temperature, usage time, measurement position, external force, etc., and the accuracy is not high; 3. The beam section has a large size, and there are safety hazards when using a steel tape measure for manual measurement. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3The utility model provides a technical solution: a detection device for the port of an arch-beam joint section, comprising a panel 1 and a pair of longitudinal stiffening ribs 2, the outer dimensions of the panel 1 match the outer dimensions of the port of the arch-beam joint section 100, a pair of longitudinal stiffening ribs 2 are fixedly installed on the back of the panel 1, and the front and rear ends of the longitudinal stiffening ribs 2 are provided with lifting holes 21.

[0019] In order to further improve the connection reliability between the longitudinal stiffening ribs 2 and the panel 1 and ensure the flatness of the panel 1, the utility model also includes a group of transverse stiffening ribs 3 fixedly installed on the back of the panel 1, and the two ends of the transverse stiffening ribs 3 are respectively fixed to the side walls of the corresponding longitudinal stiffening ribs 2.

[0020] The working principle of the utility model is: the arch-beam combination section 100 is assembled as a whole in the factory. After the assembly is completed, the port detection device of this embodiment is used for detection. The detection operation is relatively more convenient and is conducive to improving the detection accuracy and work efficiency.

[0021] The specific production of the port detection device of this embodiment is as follows: the panel 1, the longitudinal stiffening ribs 2 and the transverse stiffening ribs 3 are accurately cut by a CNC laser cutting machine, and then corrected; hoisting holes 21 are opened at the front and rear ends of the longitudinal stiffening ribs 2 to facilitate crane hoisting, and then the longitudinal stiffening ribs 2 and the transverse stiffening ribs 3 are welded to the panel 1. After welding, the flatness of the panel 1 is controlled by correction again to complete the production of the port detection device.

[0022] The operation method is: after the arch-beam joint section 100 is assembled and welded, it is placed on the platform with the port facing upwards, and the panel 1 of the port detection device is placed at the port of the arch-beam joint section 100 by a crane, and the gap or interference between the port of the arch-beam joint section 100 and the panel 1 is checked. The port deviation position is adjusted in time by flame trimming until the port of the arch-beam joint section 100 coincides with the outer edge of the panel 1, and the allowable deviation is ≤2mm.

[0023] In order to facilitate the lifting of the arch-beam joint section port detection device and improve the lifting safety, the utility model also includes a pair of auxiliary lifting components 4, which are respectively used for cooperating with the lifting holes 21 at the front end and the rear end for lifting. The auxiliary lifting component 4 includes a lifting beam 42, and a lifting ring portion 41 is fixedly provided in the middle of the lifting beam 42. The lifting ring portion 41 is used to cooperate with the hook of the crane. The two ends of the lifting beam 42 are rotatably connected with auxiliary hanging rods 44 through pin shafts 43. The lower end of the auxiliary hanging rod 44 is equipped with an auxiliary hook 45 for cooperating with the lifting hole 21. Specifically, the auxiliary hook 45 is hooked in the lifting hole 21 from the inside to the outside, and a pair of limiting slides 46 are also slidably installed at the lower end of the lifting beam 42. A supporting sleeve 47 for supporting the auxiliary hanging rod 44 is extended to the outer side of the limiting slide 46. When the supporting sleeve 47 is matched with the vertical auxiliary hanging rod 44, the limiting slide 46 is assembled and fixed with the lifting beam 42 through the fastener 48.

[0024] When in use, the auxiliary lifting assembly 4 is moved close to the lifting hole 21 through the hook of the traveling crane, the auxiliary lifting rod 44 is swung inward, and then the auxiliary lifting hook 45 is hooked on the lifting hole 21 from the inside to the outside. After the auxiliary lifting hooks 45 on both sides are hung, the limiting slide 46 is pushed outward so that the supporting sleeve 47 cooperates with the vertical auxiliary lifting rod 44. Then, the limiting slide 46 and the lifting beam 42 are fixed by the fastener 48. At this time, the supporting sleeve 47 can stably support the auxiliary lifting rod 44 to prevent the auxiliary lifting rod 44 from swinging inward and disengaging from the lifting hole 21, thereby ensuring the safety of lifting. In addition, during the lifting process, the hook of the traveling crane cooperates with the lifting ring part 41 in the middle of the lifting beam 42 to hook, so that the panel 1 can keep balance on the left and right, which can effectively prevent the panel 1 from tipping over.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
