The utility model discloses a L template structure to and set up the structure of the ascending U type cardboard of opening at the up end of L template, and the structural style who marks time that open side down is seted up in the cooperation, the construction of convenient jacking supernumerary segment down, and safe and reliable has effectively realized time operating mode of jacking supernumerary segment satisfying the construction demand.
Description
Technical field
The utility model relates to a kind of column crane mast section imported unit, and specifically jacking type standard knot imported unit under a kind of tower crane, belongs to tower crane lifting construction applications.
Background technology
Tower crane improves the lifting altitude of tower machine by the method increasing standard knot quantity.Climbing support, jacking cross beam during the jacking of tower machine, quit, the alternation that cooperatively interacts of marking time.Existingly to quit and tread structure only can be used in jacking process, the upper end that on when constructing, jacking is quit is connected with climbing support crossbeam with bearing pin, and lower end is close on the main string of mark joint is stuck in and marks time, and carries tower machine climbing support with the weight of upper-part temporarily.Because lower lifting guide support adding completes supernumerary segment work on ground, safety is high, easy to implement, therefore, at present adopt lower lifting guide support adding form of construction work, but existing upper jacking is quit with the form of marking time because the limitation of structure is only applicable to the operating mode of upper lifting guide support adding more, inapplicable when lower jacking.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides jacking type standard knot imported unit under a kind of tower crane, and structure is simple, and convenient construction is safe and reliable, effectively can realize the operating mode of lower lifting guide support adding, meet construction demand.
To achieve these goals, under this tower crane, jacking type standard knot imported unit comprises and is welded in marking time on main chord of standard section, and the main body of quitting be made up of L-type plate;
Describedly mark time as trapezium structure, lower end offers the bayonet socket that Open Side Down;
The described upper end of quitting be made up of L-type plate offers U-shaped clamp, described U-shaped clamp offers the draw-in groove of opening upwards;
Described mark time on bayonet socket and draw-in groove corresponding matching on described U-shaped clamp;
The main string of mark joint is close in the upper end of described L-type plate, and on being stuck in being marked time by U-shaped clamp, lower end is fixedly connected with climbing support crossbeam by pin-and-hole bearing pin.
Further, the contact part of described L-type plate and climbing support crossbeam is provided with backing plate.
Further, interior fagging is provided with in described L-type plate.
Compared with prior art, under this tower crane, jacking type standard knot imported unit the utility model adopts L-type plate structure, and the structure of U-shaped clamp of opening upwards is set in the upper surface of L-type plate, coordinate and offer the version of marking time that Open Side Down, convenient lower lifting guide support adding construction, safe and reliable, effectively can realize the operating mode of lower lifting guide support adding, meet construction demand.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, Figure 2 and Figure 3, under this tower crane, jacking type standard knot imported unit comprises being welded in main chord of standard section marks time 1, and 2 main bodys of quitting be made up of L-type plate 6;
Describedly mark time 1 for trapezium structure, lower end offers the bayonet socket 12 that Open Side Down;
Described by L-type plate 6 form quit 2 upper end offer U-shaped clamp 7, described U-shaped clamp 7 offers the draw-in groove 11 of opening upwards;
Described bayonet socket 12 of marking time on 1 and draw-in groove 11 corresponding matching on described U-shaped clamp 7;
The main string of mark joint is close in the upper end of described L-type plate 6, and be stuck in by U-shaped clamp 7 and mark time on 1, lower end is fixedly connected with climbing support crossbeam 3 by pin-and-hole 9 bearing pin.
Further, described L-type plate 6 is provided with backing plate 8 with the contact part of climbing support crossbeam 3.Realize reliable connection, and structural strength.
Further, interior fagging 10 is provided with in described L-type plate 6.Effective enhancing structural strength, improves security and stability.
Under this tower crane, the principle of work of jacking type standard knot imported unit is:
As shown in Figure 2, when tower machine carries out lower lifting operation, mark time 1, jacking cylinder 4, climbing support crossbeam 3, quit 2, strut bar 5 alternation.The first step, quit 2 be flapped toward inner side, the bayonet socket 12 of marking time on 1 is placed in the draw-in groove 11 of the U-shaped clamp of the opening upwards of 1 front end of quitting, reliable connection, the piston rod of jacking cylinder 4 stretches out, by tower body jack-up, the piston rod stroke of jacking cylinder 4 puts in place, strut bar 5 is flapped toward inner side, 1 to be connected with marking time, to support tower body.Second step, unclamp quit 2 with mark time 1 connection, quitting 2 is flapped toward outside, and the piston rod of jacking cylinder 4 drives climbing support crossbeam 3 to regain together.Repeat two-step action three times, tower body can be introduced a feast-brand mark with the gap on basis and save, and completes a jacking job.
In sum, under this tower crane, jacking type standard knot imported unit the utility model adopts L-type plate structure, and the structure of U-shaped clamp of opening upwards is set in the upper surface of L-type plate, coordinate and offer the version of marking time that Open Side Down, convenient lower lifting guide support adding construction, safe and reliable, effectively can realize the operating mode of lower lifting guide support adding, meet construction demand.
