Description

Technical Field

[0001] The utility model relates to the technical field of culvert installation equipment, and more specifically, the utility model relates to a culvert installation structure for an underground tunnel. Background Art

[0002] A culvert refers to a culvert or pipe gallery whose body is built with reinforced concrete box-shaped pipe sections. Existing culvert components are all prefabricated by reinforced concrete to form precast culvert components for splicing and installation. When in use, culverts often need to be combined side by side or separated for use. In underground tunnel construction, the existing installation method of culverts is mostly manual installation with the assistance of a crane. The crane is used to lift the culvert to the approximate installation position, and then manual adjustment is used to accurately position the culvert so that adjacent culverts are neatly butted. The manual adjustment method is mainly achieved by manual methods such as hammer knocking and strut pushing. The main problems are poor alignment accuracy, time-consuming and laborious installation process, and low installation efficiency. Summary of the Utility Model

[0027] One end of the main crossbeam 2 is externally fixed with an "L"-shaped baffle member 1; the end of the "L"-shaped baffle member 1 fixes the culvert. The auxiliary crossbeam 3 is slidably sleeved inside the other end of the main crossbeam 2; a rotating motor 201 is installed outside the main crossbeam 2, and the output end of the rotating motor 201 passes through the wall of the main crossbeam 2 and is connected to a rotating shaft 203. Both ends of the rotating shaft 203 are rotatably connected to the inner wall of the main crossbeam 2 through bearing seats, and a first bevel gear 202 is sleeved on the rotating shaft 203; a threaded block 206 is fixedly connected to the inner wall of the auxiliary crossbeam 3, and the threaded block 206 is sleeved on a threaded rod 207; the threaded rod 207 is horizontally arranged inside the main crossbeam 2, and one end is rotatably fixed through a fixing plate 205; the end of the threaded rod 207 extending out of the fixing plate 205 is fixed with a second bevel gear 204; the first bevel gear 202 and the second bevel gear 204 are meshed; a connecting plate 4 is fixed to the outer end of the auxiliary crossbeam 3, and a plurality of spaced strip holes 401 are formed in the connecting plate 4 for passing screws, and the connecting plate 4 is connected to the culvert through screws. Specifically, threaded holes are reserved in the culvert during pouring, and the connecting plate 4 is fixed to the culvert by screws, or anchor bolts are buried during on-site installation, the anchor bolts pass through the strip holes 401, and then nuts are used for locking.

[0028] The rotating motor 201 is fixed to the outer wall of the main crossbeam 2 through a fixing frame 208.
