The invention provides a foldable track detecting apparatus comprising a pair of folding boxes, a rotating shaft, a main box body, a fixing plate, a fixed tensioning plate, an unfolded positioning plate, a tensioning plate, a tensioning rod, a heightening plate, a vehicle body and a distance sensor. The pair of folding boxes are respectively arranged at the left and the right sides of the main box body and are connected with the main box body through the rotating shaft. The rotating shaft, the fixing plate, the fixed tensioning plate, the unfolded positioning plate, the tensioning plate and the heightening plate are respectively arranged on the main box body. The vehicle body is connected with the main box body through the heightening plate. The distance sensor is arranged on the folding box and the main box body. The invention overcomes a defect that an ordinary detection apparatus is wider than an ordinary vehicle; as the foldable track detecting apparatus is small and does not influence the safety of the vehicle running, the safety of the detection process is greatly improved; and meanwhile, the foldable track detecting apparatus has simple structure, does not increase the cost and has wide application scope.

The invention discloses a double-track tunnel based on reversible complementary ventilation. The double-track tunnel comprises an upstream tunnel, a downstream tunnel and a connecting air passage, wherein the connecting air passage is used for communicating the upstream tunnel and the downstream tunnel; a position, near the connecting air passage, of each tunnel is provided with a cross section expansion region extending to a position outside a driving building limit of the tunnel; an opening of the connecting air passage is positioned in the cross section expansion region; each cross section expansion region is provided with an air passage partition wall; the opening of the connecting air passage is separated into an air blowing opening and an air sucking opening by the air passage partition wall; an air blowing opening air valve is arranged at the air blowing opening; and an air sucking opening air valve is arranged at the air sucking opening. The air passage partition wall impedes or performs flow division on tunnel air flow flowing in the traffic flow direction, and the tunnel air flow is driven to change the flowing direction to enter the connecting air passage and is further transferred into the opposite tunnel, so that the ventilation effect between the two tunnels is effectively improved; the backflow ventilation effect is favorably improved through the air blowing opening air valve and the air sucking opening air valve; and the opening of the air passage partition wall and the opening of the connecting air passage are positioned in the corresponding cross section expansion region, so that the driving safety in the tunnels cannot be influenced.

The invention relates to a fast and labor-saving opening and closing handle mechanism of a pressure-resistant hatch cover, comprising a pressure-resistant hatch cover, a connecting shaft is vertically installed in the middle of the pressure-resistant hatch cover, and a hand wheel is installed on the top of the connecting shaft, and the hand wheel includes a hand wheel body And the handwheel ring. The handwheel body is a columnar structure that matches the top of the connecting shaft. Several telescopic components that extend outward and pass through the handwheel ring are evenly distributed along the circumference of the handwheel body. Each telescopic component is installed inside to control the extension or Shortened latch assembly. The invention extends the force arm of the handwheel, reduces the operating force, accelerates the opening speed of the hatch cover, and reduces the risk; Corrosion of components and locking components reduces material performance requirements; telescopic components have no overhang phenomenon, reducing the possibility of hooking accidents and ensuring safe operation; the invention has low manufacturing cost and reliable performance, and can also be adapted to other hatch covers .

The invention relates to the field of vehicle steering systems and particularly relates to a hydraulic steering auxiliary system which comprises a steering auxiliary system controller, a vehicle speed sensor, a steering wheel angle sensor, an engine speed sensor and an engine controller; when the steering auxiliary system controller determines that a vehicle is in a low-speed steering state according to signals of the vehicle speed sensor, the steering wheel angle sensor and the engine speed sensor, the steering auxiliary system controller controls the engine to increase the rotation speed to a steering speed value by virtue of the engine controller until the vehicle exits from the low-speed steering state, the steering auxiliary system controller stops controlling the rotation speed of the engine. When the vehicle is in the low-speed steering state, the rotation speed of the engine is controlled, so that the steering input force is improved, and the control stability of the whole vehicle is improved; during normal driving, the auxiliary system is not in charge of control, has no influence on the traffic safety, is low in cost and has extensive popularization and application value.
