This utility model discloses a pier-crossing moving device, belonging to the field of bridge construction technology. The pier-crossing moving device is located on a bridge and includes a traveling component, a lifting component, a working component, and a supporting component. The traveling component is suspended above the bridge deck and rolls in contact with the supporting guardrail on the bridge. The lifting component is installed on the traveling component and is located on one side of the supporting guardrail. The traveling component is connected to one end of the supporting component, which is located on the other side of the supporting guardrail. There is a gap between the supporting component and the supporting guardrail. The other end of the supporting component is movably connected to one side of the working component, allowing the working component to rotate relative to the supporting component. A traction rope in the lifting component is connected to the other side of the working component, which is located below the bridge. The supporting guardrail provides a gravity balance support point between the working component and the lifting component, ensuring the stability of the pier-crossing moving device during construction and reducing the impact of lateral forces on the supporting guardrail.

The utility model discloses a kind of suction grain pipe offset suction grain machine, suction grain device and suction grain pipe are arranged on walking device, suction grain pipe is connected on rotating seat, can rotate around the center of rotating seat, suction grain pipe and rotating seat are offset in the angle position inclined outer side of suction grain device, suction grain pipe can rotate in the space range of adjacent two side surfaces of suction grain device around rotating seat center.The suction grain pipe and rotating seat of the utility model are offset in the angle position inclined outer side of suction grain device, increase the working surface range of suction grain, suction grain is more convenient and fast, less time-consuming, improve the efficiency of suction grain, reduce the requirement to space volume, more convenient to walk flexibly, also more convenient to store in warehouse, reduce storage cost.

The utility model relates to the technical field of pipeline welding, in particular to a pipeline welding device which comprises a welding trolley, an annular guide rail and a ring adjusting mechanism. The welding trolley is adsorbed to the outer side of the annular guide rail and slidably connected with the annular guide rail in the circumferential direction of the annular guide rail. A fracture is axially formed in the annular guide rail, and the ring adjusting mechanism is used for annularly splicing the annular guide rail and adjusting the size of the fracture; a plurality of pressing mechanisms are fixedly arranged on the inner side of the annular guide rail in the circumferential direction and used for abutting against a pipeline. An opening is formed in the end, close to the pipeline, of the pressing mechanism, a walking part is slidably arranged in the pressing mechanism, one end of the walking part is elastically connected with the pressing mechanism through an elastic connecting piece, and the other end of the walking part extends out of the pressing mechanism through the opening. The sliding length of the walking part in the pressing mechanism is larger than or equal to the length of the walking part extending out of the pressing mechanism. And through mutual cooperation of the ring adjusting mechanism and the pressing mechanism, flexible walking can be achieved on the basis that the welding work stability is guaranteed.
