Description
Technical field
The utility model relates to a kind of novel climbing device of climbing type tower machine, relates in particular to a kind of energy jack-up whole climbing type tower machine, and a set of hydraulic jacking device making it raise along with increasing of building.
Background technology
When climbing type tower machine needs to climb, as shown in Figure 4 and Figure 5, the jacking hydraulic actuating cylinder of " layback " and coupled jacking cross beam are pushed into the main string side of tower body, matching with step plate in the end of jacking cross beam, could start jacking.When tower machine climbs, four step plates matched with jacking cross beam need the deadweight bearing whole tower machine, and this has very high requirement for step plate.During existing climbing type jacking, need artificial promotion this cover hydraulic efficiency pressure system and jacking cross beam, as shown in Figure 1, it is made to match with step plate, because this cover hydraulic efficiency pressure system of large-scale climbing type tower machine and jacking cross beam weigh one or two ton, need multiple workman to exert great efforts and could promote this cover jack-up system, and this cover jack-up system is after crossing the line of centers perpendicular with the frame that climbs, the main string of tower body can be directly swung to, tower body main chord of even damaging because conducting oneself with dignity.Whole process, namely wastes time and energy, and is fraught with risks again.Meanwhile, existing jacking step plate is cut away at iron block two angles of cuboid, as shown in Figure 2, then be welded on tower body, tower body and two angles of cutting away form two grooves respectively, and these two grooves are marked time respectively as the climbing when climbing with complete machine of marking time of jacking during stock jacking.This sharp-featured step plate, at sharp corner, easily causes very large stress to concentrate; Simultaneously owing to having cut away two angles, reduce the bonding area with tower body, cause weld seam inadequate, can only make up by increasing thickness of slab, because whole tower machine has a lot of block jacking step plate, the thickness of slab of increase can waste material very much.Therefore, from improving the Combination property of climbing type tower machine, work efficiency, receive strength rationality and safety, this set of climbing device of improvement is just seemed necessary, and this improvement has very important realistic meaning.
Summary of the invention
The purpose of this utility model is just for the weak point of above-mentioned climbing system, and the one designed is simple to operate, can the heavy jacking hydraulic actuating cylinder of automatic push-pull and jacking cross beam device, its convenient, fast, safe matching with step plate can be made, and optimal design is again carried out to step plate, make its reasonable stress, the climbing device of the climbing type tower machine that structure is attractive in appearance.
The purpose of this utility model realizes by following technique measures:
The climbing device of climbing type tower machine of the present utility model comprises the frame that climbs, jacking hydraulic actuating cylinder, jacking cross beam, step plate, guiding hydraulic cylinder, overhanging bearing; Described jacking hydraulic actuating cylinder forms by being arranged in each jacking hydraulic actuating cylinder of middle part, side before and after the frame that climbs, and described jacking hydraulic actuating cylinder lower end is hinged by bearing pin and the frame that climbs, the upper end of jacking hydraulic actuating cylinder by bearing pin and jacking cross beam hinged, jacking cross beam end mounts mutually with the step plate on the main string of tower body, guiding hydraulic cylinder upper end is hinged by the middle part of bearing pin and jacking hydraulic actuating cylinder, the lower end of guiding hydraulic cylinder is hinged by bearing pin and overhanging bearing, and overhanging bearing is welded in the middle part of the frame web that climbs.
Guiding hydraulic cylinder described in the utility model is Bidirectional self-locking type hydraulic actuating cylinder, can provide thrust, provide pulling force when tension when pressurized; Described step plate two ends are provided with eccentric bayonet socket circular arc, comparatively weld with the main string of tower body in distally apart from bias, are rounded down apart from eccentric compared with the sharp corner of nearside; The jacking axle being positioned at jacking cross beam two ends is the solid circular shafts with radiuses such as step plate bayonet socket circular arcs; Be welded with the two piece circular arc gussets isometric with cantilever plate below the cantilever plate of described overhanging bearing, above cantilever plate, be welded with the otic placode matched with guiding hydraulic cylinder.
Principle of work of the present utility model is as follows:
When climbing type tower machine needs upwards to climb, first guiding hydraulic cylinder is started, under the thrust of guiding hydraulic cylinder, jacking hydraulic actuating cylinder and jacking cross beam, rotate around bottom bearing pin, when it is crossed with the center line that the frame that climbs is perpendicular, jacking hydraulic actuating cylinder and jacking cross beam are under Gravitative Loads, have tenesmus trend, at this moment under guiding hydraulic cylinder, terminal pressure is negative, and it is regulated by self-locking, produce pulling force, control the swing speed of jacking hydraulic actuating cylinder and jacking cross beam, until when putting to that step plate nearest above it, stop swinging; Jacking hydraulic actuating cylinder is started working, and jacking hydraulic actuating cylinder is to upwards jack-up jacking cross beam, until the jacking axle of jacking cross beam end mounts mutually with the bayonet socket circular arc of step plate completely, next step just can start the jacking of whole tower machine.
The beneficial effects of the utility model are as follows:
1, change square step plate into circular arc step plate, reduce stress and concentrate, stressed more reasonable, structure is more attractive in appearance, adds the fusion length of the main string with tower body simultaneously, safe and reliable.
2, will manually promote jacking hydraulic actuating cylinder and jacking cross beam has been designed to, by guiding hydraulic cylinder hydraulic-driven, raise the efficiency, save human cost, reduce manually-operated risk.
