Background technology
The jacking of tower crane utilizes stock and hydraulic efficiency pressure system to complete, and jacking cylinder generally passes through secondary or secondary with up stroke, and tower machine is turned round to rise to desired height.Now, jacking stock has the space that can put into a standard knot, at this moment can add a joint standard knot, increases the object of supernumerary segment to reach tower machine.Jacking repeatedly, reaches desired height so repeatedly.Former main climbing structure on its stock is comprised of with hydraulic ram jacking cross beam, jacking claw or card boots and jacking, with reference to Fig. 1 a and 1b.Its jacking cross beam has two kinds of fixed forms to be fixed on marking time of standard knot, a kind of is to promote quitting of jacking cross beam and hang on standard knot marks time with artificial, another kind is to mark time and be connected with movable latch and standard knot jacking, is mainly to see that standard knot tread structure form decides that mode that adopts; Jacking claw or card boots are connected on stock, need with on manually being hung over and marking time before jacking conversion; Jacking is fixed on jacking cross beam with hydraulic ram one end, and the other end is fixed on jacking stock; Jacking stock and tower machine revolution undersetting are connected, and make tower machine be divided into two parts.The shortcoming existing is: use inconveniently, not quick, need repeatedly human assistance operation while changing step, be only applicable to two groups of jackings of joint standard knot climbing structure close or that standard knot height is short of marking time.
Summary of the invention
In order to overcome existing tower crane lifting structure, use inconvenient, not quick, need repeatedly human assistance operation, be only applicable to the mark time shortcoming of close climbing structure of two standard sets joint jacking, the utility model provide a kind of climbing structure easy to use, quick, functional, while changing step without repeatedly human assistance operation, and meet the mark time climbing structure of tower crane stock of distance of the higher and standard knot of standard knot.
The technical solution adopted in the utility model is:
The climbing structure of tower crane stock, comprise jacking stock, for jacking, hydraulic ram, standard knot are marked time and jacking claw, it is characterized in that: also comprise jacking stay bearing plate and jacking cat ladder, described jacking stay bearing plate is connected with described jacking stock by the first bearing pin, and is supported on described jacking cat ladder; Described jacking claw one end is connected with hydraulic ram with jacking, and the other end is supported on described jacking cat ladder; Described jacking is connected with jacking stock by the second bearing pin with hydraulic ram one end, and the other end is connected with jacking claw; Described jacking cat ladder is affiliated on the standard knot that the jacking stock side of hydraulic ram is installed is marked time.
Further, described jacking cat ladder by marking time, mat, square steel, strut bar, tilt prop, dividing plate and round steel form, described marking time is affiliated to and is fixed on standard knot marks time; Described marking time is welded on respectively in two mats, one side of the mat described in two is welded with respectively described tilt prop, one end of tilt prop described in two is welded to connect by described strut bar, the other end of the tilt prop described in two is welded with respectively a square steel, between square steel described in two, interval is welded with some described round steel, is welded with dividing plate between the square steel of described round steel below.
Further, described jacking claw is supported on the round steel of described jacking cat ladder.
Further, described jacking claw consists of two claws and dividing plate, and two claws and dividing plate are by being welded together.
When the utility model is used, hydraulic ram is reduced to root, (is ready to work before jacking, as removed standard knot and undersetting bearing pin, jacking stock is connected with bolt with undersetting), jacking claw is supported on the round steel of jacking cat ladder, and upwards jacking, rises to and jacking claw same position stay bearing plate, stay bearing plate is stressed, shrink hydraulic ram, until the round steel place of next joint jacking cat ladder makes jacking claw stressed at jacking cat ladder.During the utility model jacking, make whole stock and rotating part upward movement, without manually going to promote claw or going, insert movable latch, only need to observe.
The beneficial effects of the utility model are embodied in: this climbing structure is simple in structure, convenient to use, without human assistance operation jacking claw and stay bearing plate, only need before each jacking, jacking cat ladder to be hung on a uppermost joint standard knot.
