The present disclosure relates to a suspension unit and a method for taking up and transporting sausage loops with a guide rail and hooks circulating around the guide rail, where the guide rail has an elongate front side and an oppositely disposed rear side. The guide rail is inclined relative to a horizontal plane such that the front side is at a higher level than the rear side.

The invention provides an integrative bridge erection machine of a shift type transporting and erecting girder, which relates to a bridge erecting device. The invention aims at providing an integrative bridge erection machine of a shift type transporting and erecting girder and a bridge erecting method, which effectively solves of erecting a bridge in a tunnel and a first hole out of a tunnel opening and erecting a bridge with a smaller curve radius. The integrative bridge girder erection machine of the shift type transporting and erecting girder comprises a girder transporting and erecting machine and a lower girder guiding machine, wherein the girder transporting and erecting machine comprises a girder, a front running wheel group and a rear running wheel group; the lower girder guidingmachine comprises a guiding girder, front, middle and rear roller wheel legs and a girder erecting dolly; the movable girder erecting dolly is arranged on the guiding girder, the front part of a maingirder is provided with a main girder shifting and stretching section which extends forwards, the connection of the main girder shifting and stretching section and the main girder is provided with a downward shift supporting seat, and a shift supporting and moving mechanism is arranged on the girder erecting dolly and can slide along the bottom of the main girder shifting and stretching section under the shift supporting seat. When the erection moves ahead, the shift supporting and moving mechanism is raised step by step by the running wheel groups to convert the load to the girder erecting dolly step by step, thereby completing the conversion of carrying and supporting points.

The invention relates to a loading and unloading system for a distribution center type automated container terminal. The loading and unloading system comprises a plurality of quay cranes, a nearshore multipath rectangular-ambulatory-plane automatic transportation system, an elevated container automatic loading and unloading system, a storage yard, a container evacuating port side multipath rectangular-ambulatory-plane automatic transportation system, a container evacuating port transportation system, an annular special container channel and a control system. Compared with the scheme of an existing automated container terminal, the loading and unloading system for the distribution center type automated container terminal is advantaged in that the loading and unloading system is creative and unique, and is high in production efficiency, safety, automation degree and stability, and is simple in structure, simple to control and complete in scheme.

The invention discloses an intelligent head-up display system, which comprises a display assembly, an image acquisition assembly, a natural voice interaction assembly, a sensor assembly and a processor assembly. The display assembly is connected with the image acquisition assembly; the sensor assembly is connected with the processor assembly; and the image acquisition assembly is connected with the processor assembly. Compared with a convention head-up display system, the intelligent head-up display system can support more interaction control and can realize voice scheme interaction adoption, and meanwhile, can install various third-party applications to expand and enrich functions; furthermore, the intelligent head-up display system, carried with various sensors, can connect external equipment; and besides, the intelligent head-up display system has a camera module, which faces to the inner portion of a vehicle, so that the behavior and state of a driver can be identified, and safe driving reminding function and interaction control function can be realized.

The invention discloses a turning-over machine which comprises a machine frame, a rotating mechanism, a moving mechanism and at least four sets of fork rods. The rotating mechanism and the moving mechanism are both installed on the machine frame. The rotating mechanism is provided with at least two rotating discs fixed at two ends of a rotating shaft. Each rotating disc is provided with a moving roller supporting and limiting the fork rods to conduct linear movement. Two pairs of fork rods are symmetrically and vertically installed on the moving rollers with the axis of the rotating shaft as the symmetrical center. Two pairs of synchronous gears are connected coaxially, meshed with synchronous racks on the outer sides of the two pairs of fork rods and vertically installed on the rotating shaft. When a moving gear of the moving mechanism rotates, the moving gear drives moving racks on the lower sides of the lower fork rods to move linearly. Under the effect of the synchronous gears and the synchronous racks, moving racks on the upper fork rods also move in the same direction synchronously. When the two pairs of fork rods clamp a plate from the plate feeding position, after the rotating mechanism rotates through 180 degrees, the two pairs of fork rods are driven by the moving mechanism to be pushed backwards to the original plate feeding position to achieve the aim that the two pairs of fork rods clamp the plate in a circulation mode and turn over the plate. Due to the fact that the fork rods only rotate on the upper half ring of the turning-over machine, working height of the turning-over machine is reduced.

The invention relates to the technical field of underground engineering, in particular to a construction method for excavating deep foundation ditch, wherein the bottom of an excavating machine is provided with a walking device to realize and finish selection of excavating positions, a support beam along the vertical direction of the excavating machine is arranged into a perpendicular adjustable beam which can be vertically adjusted along the vertical direction to realize adjustment of working height of the excavating machine, and a support beam along the horizontal direction of the excavating machine is arranged into a level adjustable beam which can be horizontally adjusted along the horizontal direction to realize adjustment of working scope of an excavating bucket of the excavating machine. After the selection and regulation are finished, the excavating is finished. The invention has the advantages of high safety when in construction, high efficiency, energy-saving, and environmental protection, and can excavate in omnibearing and in multi-angles.
