The specific embodiment
Core of the present utility model provides a kind of frame that climbs of tower crane, and this frame that climbs simple in structure is detachable when idle, can reduce body of the tower load.Another core of the present utility model provides a kind of tower crane that comprises the above-mentioned frame that climbs.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Here it is pointed out that the related noun of locality such as forward and backward, upper and lower is to be arranged in figure and parts position each other defines with parts among Fig. 3 to Fig. 6 herein, just clear and convenient for the expression technology scheme.The use that should be appreciated that the described noun of locality should not limit the scope that the application asks for protection.
Please refer to Fig. 3 to Fig. 6; Fig. 3 provides the structural representation of a kind of specific embodiment of frame of climbing for the utility model; Fig. 4 is the structural representation of the main leaf of the frame that climbs shown in Fig. 3; Fig. 5 is the structural representation of the anter of the frame that climbs shown in Fig. 3; Fig. 6 is the structural representation of the rear panel of the frame that climbs shown in Fig. 3.
In a kind of concrete embodiment, the frame 10 that climbs of tower crane provided by the utility model comprises two main leaves 11, anter 12 and rear panel 13; Two main leaf 11 symmetric arrangement, described main leaf 11 comprises two main chords that be arranged in parallel 111, be arranged at two between the main chord 111 cross bar 112 and be arranged at web member 113 (being shown among Fig. 4) between the cross bar 112, all can be fixedly connected by welding between described main chord 111 and described cross bar 112, described cross bar 112 and the described web member 113, not only easy but also reliable.
The similar of described anter 12 and described rear panel 13 and described main leaf 11 with reference to figure 5 and Fig. 6, repeats no more here.
Two main leaf 11 symmetric arrangement, described anter 12 is arranged between the front main chord bar of two main leaves 11, described rear panel 13 is arranged between the post main chord bar of two main leaves 11, it is tetragonal framework that described main leaf 11, described anter 12 and described rear panel 13 surround cross-sectional plane, promptly the climb frame body of frame 10, as shown in Figure 3.
Wherein, described main leaf 11 removably connects with described rear panel 13 with described anter 12, described main leaf 11.The mode that removably connects has multiple, and wherein a kind of easy and failure-free mode is a bolted connection.
The length of described anter 12 is less than the length of described rear panel 13, so unlimited utensil receiving opening 14 (being shown among Fig. 3) is formed at the top of the framework that surrounds in main leaf 11, anter 12 and rear panel 13, is used for tower crane and introduces standard knot to be installed when raising.
It is pointed out that differing partly of described relatively rear panel 13 length of described anter 12 length can be provided with according to actual demands of engineering, is as the criterion so that the utensil receiving opening 14 that frame 10 tops of climbing form can facilitate the introduction of standard knot to be installed.
The top of the main chord 111 of described main leaf 11 also is installed with supporting seat 114, and the top of said framework has four supporting seats 114, is connected with stay bearing plate 115 on the described supporting seat 114, is used to support the top assembly of described tower crane.
In engineering reality, set up when maybe needing to raise at tower crane, the frame 10 that climbs is sleeved on the body of the tower of tower crane, the stay bearing plate 115 on frame 10 tops of climbing supports the top assembly of tower cranes, jack-up system by the frame 10 that climbs is with the top assembly jack-up of tower crane, the center that the standard knot of introducing can be introduced the frame 10 that climbs by the utensil receiving opening 14 on frame 10 tops of climbing, and be connected with mounted bottom standard knot, so, be about to the raise height of a standard knot of tower crane, so repeatedly till tower crane sets up or is increased to desired height.
After tower crane rises to desired height, the frame 10 that climbs is in idle state, that is to say, only when tower crane sets up or raise, need realize by the frame 10 that climbs, all the other states 10 on frame that climbs is in idle state since between the main leaf 11 of the described frame 10 that climbs and anter 12 and main leaf 11 and the rear panel 13 for removably connecting, when the frame 10 that climbs is in idle state, the frame 10 that can will climb is removed, and alleviates the load of stacker crane body.In addition, the frame 10 that climbs of dismounting also can be used for setting up or raising of other tower cranes of same workyard, and promptly many tower cranes can the shared frame that climbs, and reduces use cost.
Because the slice structure of frame 10 for removably connecting that climb of tower crane can be chip with frame 10 dismountings of climbing when transportation, save transport space, convenient transportation reduces traffic cost.
The frame that climbs of tower crane provided by the utility model is improved to the slice structure that removably connects with the frame that climbs of integral solder structure of the prior art, after tower crane lifting finishes, when the frame that climbs is in idle state, the frame that climbs can be removed, to reduce the load of body of the tower.Because the frame that climbs is detachable, many tower cranes can the shared frame that climbs, and reduces use cost.In addition, because the described frame that climbs is the detouchable slice structure, so convenient transportation can reduce traffic cost.
Except the frame that climbs of above-mentioned tower crane, the utility model also provides a kind of tower crane, comprises body of the tower and the frame that climbs that is sleeved on the described body of the tower, and the described frame that climbs is specially the above-mentioned frame that climbs.
Because the above-mentioned frame that climbs has above-mentioned technique effect, also possesses above-mentioned technique effect so have the tower crane of this frame that climbs, and repeats no more here.
Other each several part structures of above-mentioned tower crane can also repeat no more here with reference to prior art.
More than the tower crane provided by the utility model and the frame that climbs thereof are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
