Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing.
[0016] Such as figure 2 As shown, a connection structure between the main chord and the web of a tower crane includes the main chord 1 and the web, the web includes the diagonal web 2 and the beam web 3, the two ends of the beam web 3 and the main The chord 1 is connected, and one end of the diagonal web 2 is connected with the main chord 1, and the main chord 1 is detachably connected with the diagonal 2 and the beam web 3.
[0017] Preferably, both ends of the oblique web member 2 and the beam web member 3 are connected by pins, and the two ends and the middle part of the main chord 1 are respectively welded with ear plates IB and ear plates IIC, and the pins pass through the ear plates IB or lug plate IIC and the ends of the diagonal web 2 or the beam web 3 realize the connection of the main chord 1 with the diagonal 2 and the beam web 3 .
[0018] Preferably, at leas...

The invention discloses a connecting structure of main chords and web members of a tower crane. The connecting structure comprises the main chords (1) and the web members. The web members comprise inclined web members (2) and beam web members (3). The two ends of the beam web members (3) are connected with the main chords (1) on the two sides. One ends of the inclined web members (2) are connected with the main chords (1). The main chords (1) are detachably connected with the inclined web members (2) and the beam web members (3). The overall connecting manner of the main chords and the web members is changed into pin shaft connection from welding, the installing of the web members is facilitated, the difficulty degree in the installing process is lowered, and installing is flexible. Meanwhile, during loading delivery, all connecting pin shafts between the main chords and the web members can be dismounted, the web members serve as single objects to be bundled and delivered, a large amount of occupied space is saved, the delivery car using cost is saved, and the delivery efficiency is improved. By means of the application of the technology, safety and convenience in the installing process can be well improved, and meanwhile the delivery and transportation cost is reduced to a great extent.
Description
technical field [0001] The invention relates to a connection form of a main chord and a web, in particular to a connection structure between a main chord and a web of a tower crane, and belongs to the technical field of connection between a main chord and a web of a tower crane. Background technique [0002] At present, the tower crane frame is used as a truss structure to bear the vertical force and bending moment when the upper part of the tower crane is raised or lowered. It is mainly composed of main chords, beams and web members. It is connected with the main string by welding. Such as figure 1 As shown, the webs include diagonal webs 2 and beam webs 3, one end of the diagonal webs 2 is welded on the main chord 1, and the other end is welded on the gusset plate A; the beam webs 3 are arranged horizontally, and both ends are directly welded on main string 1. The structure has the following problems in the actual operation process: [0003] 1. The web rod and the main...
