Abstract

A road bridge width limiting device is composed of a flip plate, a support spring, a limit member, a pull rod and an outer support spring. The bottom of the moving part is mounted with a moving wheelthrough a connecting part and a rotating shaft, and the outside of the moving shaft is provided with threads, and the moving shaft is installed in the inside of the rotating part through threads; theinsert on the inner side of the tensioning member is installed inside the insert sliding groove on the inner side of the rotating member in an inserting manner, and a manual lever is mounted on the outer edge position of the tension member by welding, and the outer end of the manual lever is provided with a limited position lever through a mounting hole. The rotating part here plays the rotationalpower transmitted by the receiving manpower., the rotating member transmits the power to the moving shaft through the internal thread, so that the moving shaft drives the moving member to move to different positions, thereby limiting the width of the road or the bridge, and the insert in the middle position of the rotating member is embedded into the inside of the fixed groove installed in the middle position of the main body.

Description

technical field [0001] The invention belongs to the technical field of width limiting devices and road facilities, and more specifically relates to a width limiting device for road bridges. Background technique [0002] There will be a width-limiting door at the head end of the road or bridge to prevent heavy or special vehicles from entering the road and causing damage, or entering the bridge, so that the bridge cannot bear the load and breaks. [0003] For example, the application number: CN201610441759.2 relates to a road bridge width limiting device, including a pre-buried underground base, characterized in that: the upper surface of the base is provided with grooves, and the bases on both sides of the groove are provided with A support block, the top of the support block is provided with a beam, the upper surface of the beam is provided with a chute, a slider is embedded in the chute, a support column is provided on the slider, and the chute in the chute Through holes ...
