Hydraulically-driven roadblock machine

Abstract

The invention discloses a hydraulically-driven roadblock machine, which comprises a base, a cover plate and a hydraulic driving device. The cover plate is installed on the base. The hydraulic driving device is coupled on the cover plate and comprises a hydraulic source, a transmission mechanism, a rolling shaft, an inclined block, a cover plate supporting rod and an elastic piece. One end of the cover plate is fixedly hinged on the base. The hydraulic source is coupled to the rolling shaft through the transmission mechanism. The rolling shaft is arranged in a way that the rolling shaft can be driven by the transmission mechanism and can roll on the inclined block to move up, wherein the upwards moving direction faces towards one side of the fixed end of the cover plate. The elastic piece is arranged in a way that the elastic piece can transmit force to the rolling shaft to enable the rolling shaft to be restored downwards along the inclined block when the hydraulic source is turned off. The first end of the cover plate supporting rod is hinged on the rolling shaft. The second end of the cover plate supporting rod is hinged on the internal side of the cover plate. The hydraulically-driven roadblock machine provided by the invention ahs the advantages of compact and ingenious structure, small size, light weight, small thickness and wide application scope.

Description

technical field [0001] The invention relates to channel roadblock equipment, in particular to a hydraulically driven roadblock machine. Background technique [0002] Due to structural design defects, the currently known hydraulic roadblocks are all giant-sized, and installation requires trenching on the road surface and burying the roadblocks underground as a whole, resulting in a very large amount of construction; in addition, already Due to the complex structure and large size of the known ground-mounted roadblocks, its overall height (height in the non-intercepting state) is difficult to achieve less than 90mm, so there are restrictions on the chassis of passing vehicles, which will not only affect The normal traffic of vehicles is affected, and it also affects the application of roadblock machines in many places. Contents of the invention [0003] The main purpose of the present invention is to provide a hydraulic roadblock machine with a compact and ingenious structu...
