Locking structure of dike height-limiting portal frame

Abstract

The invention provides a locking structure of an embankment height limiting portal frame. The locking structure comprises a lock box, a spring bolt and a lock rod, the lock box is fixedly connected inthe cross beam of the embankment height-limiting portal, a moving slideway allowing the spring bolt to reciprocate is arranged in the lock box, the spring bolt is matched with the lock box, a lock groove matched with the spring bolt is formed in the stand column of the embankment height-limiting portal, and a locking hole is formed in the end face of the spring bolt; a lock hole allowing the lockrod to enter is formed in the bottom of the lock box, the lock rod comprises a pipe body, a flexible shaft and a lock head, the outer contour of the lock head is matched with the locking hole of thespring bolt, a traction groove is formed in the outer wall of the lock head, the lock head is installed at the initial end of the pipe body and fixedly connected with the initial end of the flexible shaft, and the flexible shaft is sleeved with the pipe body. The locking structure of the embankment height limiting portal frame can be opened, so that the cross beam and the stand column of the embankment height limiting portal frame are separated, large emergency rescue and disaster relief vehicles are allowed to pass through an embankment top road, and the main structural strength of the locking structure of the embankment height limiting portal frame is also particularly enhanced.

Description

technical field [0001] The invention relates to a locking structure of an embankment height-limiting mast. Background technique [0002] The main purpose of the embankment height-limiting gantry is to restrict overweight and super-high social vehicles from driving on the road on the crest of the embankment and damage the embankment and the road surface. During an emergency or flood control period, the embankment height-limiting gantry should be able to open, allowing large rescue and disaster relief vehicles to pass on the embankment road, but the existing embankment height-limiting gantry does not have such a structure, and it lacks a method that can prevent dikes from The locking structure of the embankment height-limiting mast that the height-limiting mast can be opened at will. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a locking structure of the dike height-limiting mast which has a reasonable structur...
