The utility model provides a kind of track fastener oiling device in the technical field of track fastener oiling, including oiling frame and power frame, the tail end of oiling frame is detachably movably connected with the front end of power frame, the bottom four corners of oiling frame are distributed with four first track wheels, the left and right sides of oiling frame are each equipped with extension frame, the bottom of extension frame is each equipped with multiple proximity sensors, oiling frame is equipped with oiling assembly, oiling assembly includes multiple oil nozzles, multiple oil nozzles are symmetrically distributed on the extension frame of the two sides of oiling frame, two pumps are also installed on oiling frame along the symmetric distribution of oiling frame middle part;The bottom four corners of power frame are distributed with four second track wheels, power assembly is installed on power frame, power assembly drives device to walk by itself, oiling is carried out by automatic detection by pump and proximity sensor, the track fastener on the left and right sides of two tracks can be simultaneously oiled, oiling efficiency is greatly improved, and the labor intensity of operator is reduced.

The sectional type tensioning structure is characterized in that a plurality of pole frames are axially arranged and axially compressed through a positive end pressing plate and a negative end pressing plate, one or a plurality of middle frames are axially arranged among the pole frames at intervals, the middle frames radially extend to protrude out of the outer contours of the pole frames, and the outer contours of the middle frames extend out of the outer contours of the pole frames. The radial outer edges of the middle frame, the positive end pressing plate and the negative end pressing plate form spaced fixing parts, and every two adjacent fixing parts are fixed and tensioned through a tensioning mechanism. The sectional type connection mode can disperse pressure and pulling force borne by each small chamber pole frame, effectively prevents the pole plates and the gaskets from drooping, reduces risks of pole plate dislocation and sealing failure, and improves stability and reliability of the electrolytic cell.

The utility model discloses a bridge expansion joint's water stop device, features include multistage along the length direction of bridge expansion joint head -to -tail connected water stop unit, and water stop unit includes two support hanging plate, two connecting hanging plate and the open upward U shape elastic rubber water stop belt, two support hanging plate symmetrical fixed setting on the two side walls of bridge expansion joint, and the upper portion of each connecting hanging plate is suspended with the lower portion of corresponding one support hanging plate between through the suspension connection mechanism suspended connection, and the both sides of U shape elastic rubber water stop belt respectively upwards bending and through a plurality of detachable pressure device with the lower portion of one connecting hanging plate fixed seal connection, and the edge of the support hanging plate of two adjacent water stop units is mutually overlapped and fixedly connected between, and the edge of the U shape elastic rubber water stop belt of two adjacent water stop units is mutually overlapped and fixed seal connection between, advantage is convenient to install, easy to maintain, can gather and clean up sundries effectively and has strong adaptability.

This utility model discloses a thermal oil dryer, including a thermal oil dryer body. The inner wall of the thermal oil dryer body is provided with a heat insulation layer, and a circulating oil pipe is provided on the inner side of the heat insulation layer. Both the inner and outer end faces of the circulating oil pipe are provided with high-temperature resistant shaping plates. A base is provided at the bottom of the interior of the thermal oil dryer body, and a movable drying box is located above the base. Universal wheels are provided on both sides of the bottom of the movable drying box. This utility model separates the movable drying box and the circulating oil pipe into two parts. This structure simplifies maintenance, allowing the movable drying box to be removed separately, exposing the internal circulating oil pipe for easy repair or cleaning of its interior and surface. This simplifies maintenance procedures and saves time and effort. It also facilitates cleaning of the movable drying box without worrying about moisture entering the electrical components, making it easier to remove stubborn stains.
