The utility model discloses a wedge-shaped jacking mechanism, which comprises a jacking base, a lifting jack, an unloading jack, a wedge-shaped jacking mechanism and a wedge-shaped jacking mechanism, and is characterized in that a jacking jack and an unloading jack are horizontally arranged on the jacking base; the wedge-shaped block group comprises a lower wedge-shaped block and an upper wedge-shaped block, the lower wedge-shaped block and the upper wedge-shaped block are oppositely arranged up and down, and the opposite end surfaces of the lower wedge-shaped block and the upper wedge-shaped block are inclined surfaces with the same slope; the movable end of the jacking jack and the movable end of the unloading jack are both connected with the lower wedge-shaped block and used for driving the lower wedge-shaped block to horizontally slide along the jacking base, and then the upper wedge-shaped block is driven to move up and down in the vertical direction relative to the jacking base. According to the bridge support, jacking operation can be carried out in a small space, jacking of a large structure can be achieved through small jacking force, and therefore maintenance and replacement of the bridge support are achieved.

This utility model belongs to the field of automatic feeding technology, and particularly relates to an automatic feeding production line. An automatic feeding production line includes a workbench and a conveyor line. A carrier is conveyed on the conveyor line, and multiple sets of stopping mechanisms are provided on the conveyor line for stopping the carrier. A lifting mechanism for lifting the carrier is provided between the stopping mechanisms at the feeding station. Conveyor belt assemblies for conveying upper and lower housings are respectively provided on the workbench on both sides of the conveyor line. A feeding robot is provided on one side of each conveyor belt assembly. Upper housing contouring grooves and lower housing contouring grooves are provided on the carrier. The feeding robot can transfer the upper and lower housings from the conveyor belt assemblies into the upper and lower housing contouring grooves, respectively. This utility model can automatically and synchronously feed and convey the upper and lower housings of sensors, and has the advantages of high feeding efficiency and high degree of automation.

The utility model relates to a wheel holding type transport vehicle which comprises a frame structure. The walking system is arranged at the bottom of the frame structure; the jacking mechanism is arranged on the frame structure and comprises a driving wedge plate capable of moving horizontally and a lifting wedge plate capable of moving vertically, and the driving wedge plate is in sliding fit with the wedge surface of the lifting wedge plate; the jacking mechanism and the wheel holding mechanism are arranged on the lifting wedge plate, the wheel holding mechanism is arranged on the lifting wedge plate and comprises a rear clamping piece capable of moving horizontally and a front clamping piece capable of moving vertically, and the rear clamping piece and the front clamping piece are correspondingly arranged. The jacking height of the jacking mechanism and the distance between the two clamping pieces of the wheel holding mechanism can be adjusted according to different sizes of airplane wheels, the adaptability is high, the production and maintenance cost is low, and the safety performance is high.
