Abstract
The utility model discloses a gantry with a self-locking function. The gantry comprises a cross beam and two gantry supporting legs; a strong tamping machine suspension device is fixed at the upper end of the cross beam; friction structures fixed with each other through a bracket are arranged at two internal ends of the cross beam respectively; the upper ends of the two gantry supporting legs are fixedly connected to the two ends of the cross beam respectively; and the lower ends of the two gantry supporting legs are fixed on a gantry supporting leg seat respectively and are locked by a locking structure on the gantry supporting leg seat. Through the adoption of a self-locking structure and the friction structures, the inclination of the gantry during the tamping process can be avoided, and the stability is good; a stay bar inside the gantry is replaced with an external tightening structure, so that the possibility that a pounder is collided with the stay bar in lifting process is avoided; and the whole gantry is fixed on the strong tamping machine suspension device through four fastening bolts to prevent the gantry from swaying left and right in moving a tamping point. The utility model has the advantages of simplicity, practicality, safety, and convenience in operation.

The utility model content
The purpose of this utility model provides a kind of door frame with auto-lock function, can effectively avoid ramming the danger of tumbling of door frame in the process, and good stability is safe and reliable, saves manpower.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of door frame with auto-lock function, wherein, comprise a crossbeam and two door frame supporting legs, described crossbeam upper end is fixed on the dynamic compaction machinery suspension arrangement, the inner two ends of described crossbeam are respectively arranged with the friction structure that interfixes by support, the upper end of described two door frame supporting legs is fixedly connected on the two ends of described crossbeam respectively, and the lower end is separately fixed on the door frame supporting leg seat and by the latch-up structure on the described door frame supporting leg seat and locks.
Above-mentioned door frame with auto-lock function, wherein, described crossbeam two ends also are provided with the tension structure and are connected with described door frame supporting leg.
Above-mentioned door frame with auto-lock function, wherein, described tension structure comprises stay cord support and stay cord, and the upper end of described stay cord support is welded on the upper face of described crossbeam, the lower end is connected with an end of described stay cord, and the other end of described stay cord is fixedly connected on the described door frame supporting leg.
Above-mentioned door frame with auto-lock function, wherein, described crossbeam comprises upper face, described friction structure upper end is affixed with described crossbeam upper face.
Above-mentioned door frame with auto-lock function, wherein, described door frame supporting leg is mainly truss or tubular stent structure, and the upper end is provided with waist shape connecting hole, and the lower end is provided with circular connector.
Above-mentioned door frame with auto-lock function, wherein, described door frame supporting leg seat comprises base, is fixed with mount pad on the described base, described latch-up structure is positioned on the described mount pad.
Above-mentioned door frame with auto-lock function wherein, is reinforced by gusset between described mount pad and the described base.
Self-locking structure of the present utility model and friction structure make can avoid ramming the danger that the door frame existence is tilted in the process, good stability in ramming operation process; And cancelled the strut of door frame inside, changed the outside tension structure of using into, the possibility of collision strut when avoiding hammer ram to promote; Door frame integral body is fixed on the dynamic compaction machinery suspension arrangement by four fastening bolts, avoids the phenomenon of the easy double swerve of door frame in the process of mobile tamping point position to occur; Reduce underworker to 2 people; Has simple, practical, safe, easy to operate advantage.
