Zusammenfassung: | The invention discloses a lagging jack mounting clamp and lagging jack mounting equipment. The lagging jack mounting clamp comprises a lifting arm seat, a cross beam and two longitudinal beams. The cross beam is movably installed on the lifting arm base and extends in the front-back direction. The longitudinal beams extend in the left-right direction, and the two longitudinal beams are connected to the two ends of the transverse beam in the front-back direction. Wherein the length of each longitudinal beam can be adjusted so as to adapt to supporting arch frames with different specifications. The length of the longitudinal beam is adjusted, so that the length of the longitudinal beam is changed according to the change of the total length of the multi-truss arch frame, and the tail end of the longitudinal beam can be ensured to be in contact with and support the outermost two-truss arch frame under the condition that the inter-truss spacing and/or the truss number of the multi-truss arch frame are/is not unifo |
