The invention provides a guardrail system of a vehicle special for engineering. The guardrail system comprises a rail, at least two support bars, elastic pieces and a control mechanism. Tops of the support bars are hinged with the rail, and bottoms of the support bars are hinged with an upper platform. The elastic pieces are connected between the upper platform and the support bars and provided with restoring force enabling the support bars to be lifted up during deformation. The control mechanism is connected with the rail or the support bars, is capable of driving the rail to descend and comprises a crankshaft, a control lever and a rocker, wherein the crankshaft can rotate around the own axis, the control lever is fixed at a spindle end of the crankshaft, the rocker is disposed on the upper platform and located below one of the support bars, the rocker is provided with a first free end and a second free end with the middle position serving as a fulcrum, the first free end is hinged with a crank end of the crankshaft, and the second free end is hinged with the support bars or the rail and used for locking a locking seat of the control lever. The height of the guardrail system is controlled mechanically, the structure is simple, and the cost is low. The invention further provides a vehicle special with the guardrail system for engineering.
Description
technical field [0001] The present invention relates to the technical field of engineering special vehicles, and more specifically, relates to a guardrail system for engineering special vehicles. The present invention also relates to a special engineering vehicle with the aforementioned guardrail system. Background technique [0002] In order to ensure the safe walking of engineering special vehicles, relevant regulations limit the height of vehicles to less than 4m. For tank vehicles, it is often designed as a tank that can load the cargo as much as possible, so most tank vehicles are relatively tall. The top of the tank truck is equipped with a mechanism that needs to be operated, such as a feeding device, so the top of the vehicle is equipped with an upper platform. In order to ensure the safety of the operator, it is necessary to install a guardrail on the upper platform. [0003] The guardrails installed on the upper platform of existing tank vehicles are divided into ...
