Abstract
The utility model relates to a connecting sleeve stiffener, a connecting sleeve is flushed with the lower end of a main chord, the connecting sleeve stiffener is arranged on the two upper edges of the connecting sleeve, a connecting sleeve is flushed with the upper end of the main chord, the connecting sleeve stiffener is obliquely connected to the connecting sleeve and the main chord. The main chord is free of crack while in use, thereby ensuring the service life of tower cranes.
Description
One, technical field
The utility model is used for the adapter sleeve of standard knot of adapter sleeve, the turning down fast-assembling tower machine of standard knot, transition segment, the base section of self-raising tower crane.
Two, background technology
The adapter sleeve of the standard knot of existing self-raising tower crane, transition segment, base section does not have the adapter sleeve brace panel.Turning down fast-assembling tower standard knot adapter sleeve does not have the adapter sleeve brace panel, and crackle appears in main chord easily in the process of using.
Three, utility model content
1. the purpose of this utility model is a kind of suitable adapter sleeve brace panel of design.On the standard knot of self-raising tower crane, turning down fast-assembling tower crane, transition segment, base section, use.
2. the scheme of adapter sleeve brace panel solution is: adapter sleeve brace panel 3 is connected with main chord 1 with adapter sleeve 2, and adapter sleeve 2 is concordant in main chord 1 lower surface, and the adapter sleeve brace panel is connected with main chord 1 position symmetric arrangement at adapter sleeve 3.The adapter sleeve brace panel dimensional data of column crane mast section.Adapter sleeve brace panel 3 is characterized by size, radian, the gradient according to the size of the diameter decision adapter sleeve brace panel 3 of main chord 1 size of standard knot, transition segment, base section and adapter sleeve 2.Adapter sleeve brace panel 3 height dimension scopes are 60～160, the width dimensions scope is 30～80, the gauge scope is 8～50.The radian range of sizes is R2～80, and the angular range of gradient is 60 °～160 °.The adapter sleeve 2 of standard knot, transition segment, base section is in main chord 1 upper surface flush arrangement, adapter sleeve brace panel 3 both sides below adapter sleeve 2 are arranged, adapter sleeve brace panel 3 width dimensions scopes are 30～80 concordant with adapter sleeve 2 lower surfaces, the height dimension scope is between 30 °～60 ° of 60～160 same main chord [1] the bonded assembly angles, connect with electric welding, adapter sleeve 2 is concordant in main chord 1 lower surface, and adapter sleeve brace panel 3 connects with electric welding in adapter sleeve 2 and main chord 1 position symmetric arrangement.
3. the utility model is compared with known technology, and adapter sleeve brace panel 3 is connected with main chord 1 with adapter sleeve 2, and adapter sleeve 2 is concordant in main chord 1 lower surface, and the adapter sleeve brace panel is connected with main chord 1 position symmetric arrangement at adapter sleeve 3.Main chord crackle can not occur in the process of using.Guaranteed the service life of tower machine.
Four, description of drawings
Five, specific embodiment
1,2,3,4,5,6 describe in conjunction with the accompanying drawings: accompanying drawing the 1,2, the 3rd, QTZ80 (5613) column crane mast section, adapter sleeve brace panel 3 are implemented figure with main chord [1], adapter sleeve 2.According to the diameter of main chord 1 and adapter sleeve 2, main chord 1 is square tube 135*135*12, and the diameter of adapter sleeve 2 is 80, long 160.Adapter sleeve brace panel 3 accompanying drawings 4 front view left side height dimensions 81, the right height dimension 80, width dimensions 40, go up left radian R3, go up 97 ° of R of right corner, bottom left radian R8, R49 along circle connect, 83 ° of bottom right angles.Adapter sleeve brace panel 3 accompanying drawings 5 left view width dimensions 20.The adapter sleeve 2 of standard knot is in main chord 1 upper surface flush arrangement, adapter sleeve brace panel 3 both sides below adapter sleeve 2 are arranged, it is 40 concordant with adapter sleeve 2 lower surfaces that adapter sleeve brace panel 3 is of a size of, and is of a size of 81 with about 45 ° of main chord 1 bonded assembly angle, connects with electric welding.Adapter sleeve 2 is concordant in main chord 1 lower surface, and adapter sleeve brace panel 3 connects with electric welding in adapter sleeve 2 and main chord 1 position symmetric arrangement.
Claims (1)
1. adapter sleeve brace panel, it is characterized in that: adapter sleeve brace panel [3] is connected with main chord [1] with adapter sleeve [2], and adapter sleeve [2] is concordant in main chord [1] lower surface, and adapter sleeve brace panel [3] is connected with main chord [1] position symmetric arrangement at adapter sleeve [2].
