Description

Technical Field

[0001] The utility model relates to a welding tool for embedded bolts, in particular to a welding tool for catenary embedded bolts based on urban rail transit, belonging to the technical field of catenary installation. Background Technique

[0002] In the construction of flexible catenary in urban rail transit, the production of catenary support foundation is a key process in the construction of flexible catenary. During the production of catenary support foundation, the embedding quality of anchor bolts will directly affect the subsequent construction of catenary support erection process. The existing embedding of catenary support anchor bolts mainly realizes the positioning of anchor bolts through the welding of steel bars and steel plates. Smooth round steel bars are used as stirrups for anchor bolts, and steel plates with a certain thickness are welded and fixed at the junction of the embedded section and the exposed section of the anchor bolts to make one by one embedded parts. In this process, a welding tool for catenary embedded bolts is often needed to position the installation position of the embedded bolts.

[0003] The existing welding tool for embedded bolts, such as a catenary support foundation embedded bolt with a spirit level fixture disclosed in Patent No. CN209082540U, ensures the verticality and spacing accuracy of the embedded bolts of the catenary column foundation during use, creating favorable conditions for the subsequent installation of catenary columns. However, this kind of welding tool for embedded bolts only involves a steel plate structure. When installing the embedded bolts, the embedded bolts are extremely easy to shift due to construction external forces and concrete deformation external forces, resulting in deviation of the verticality of the embedded bolts and affecting the construction quality.
