Detailed Description

In order to make the technical purpose, technical solutions and advantageous effects of the present invention clearer, the technical solutions of the present invention are further described below with reference to the accompanying drawings and specific embodiments.

The utility model relates to a quick assembly disassembly cover frame's concrete embodiment suitable for large-scale tower machine, as shown in fig. 1-4, including last piece truss I1, last piece truss II 2, lower piece truss I3 and lower piece truss II 4, as shown in fig. 2-3, last piece truss I, last piece truss II, lower piece truss I and lower piece truss II are monolithic structure respectively, the monolithic structure that chord member and web member welded firmly promptly. The upper piece truss I1 and the lower piece truss I3 are detachably connected to form a single piece truss I together, the upper piece truss II 2 and the lower piece truss II 4 are detachably connected to form a single piece truss II together, and the single piece truss I is detachably connected with the single piece truss II. Namely, the sleeve frame is divided into an upper section and a lower section in the height direction, thereby being beneficial to processing and manufacturing. The sleeve frame is divided into a left piece and a right piece in the width direction, so that the transportation is facilitated, the overrun is avoided, and the mounting connection surface is reduced.

Specifically, the upper piece truss I1 and the lower piece truss I3 and the upper piece truss II 2 and the lower piece truss II 4 are connected through flanges respectively. Because the structural stress needs to ensure that the flange connecting surface can resist shear and has no displacement, if the conventional flange connection is adopted, the flange connecting surface needs to be matched with a hinged hole for bolt connection. But the hinge bolt is more precise than the common bolt in fit clearance, the assembly and disassembly are very difficult, each bolt needs to be knocked by a sledge hammer for disassembly and assembly, the damage rate to the thread is extremely high, and the use of parts which are frequently disassembled and assembled is very inconvenient. Therefore, the utility model discloses a flange adopts ordinary bolt, the utility model discloses a mounting structure that stock adopted ordinary bolt and locating pin 5 to combine.

The positioning pins 5 are arranged on the flange surface, and the central line of the flange hole is parallel to the central axis of the positioning pins 5. Specifically, a positioning pin 5 is arranged on the flange faces of the upper end faces of the upper piece truss I1, the upper piece truss II 2, the lower piece truss I3 and the lower piece truss II 4 respectively, and positioning grooves matched with the positioning pins are arranged on the flange faces of the lower end faces of the upper piece truss I1 and the upper piece truss II 2 respectively. The positioning pin 5 comprises a cylindrical pin section (lower section) and a tapered pin section (upper section) which are integrally formed, the cylindrical pin section replaces a hinged bolt to play a role in shearing resistance and ensuring that the flange connection has no displacement, and the positioning pin is matched with a common bolt to play a role in tension resistance. The taper pin section has the tapering to when the equipment closes the mouth, have the guide effect, conveniently identify the position groove, effectively improve the installation effectiveness. The connection mode not only keeps the advantage that the hinged bolt has better shearing resistance, but also keeps the advantage that the common bolt is convenient to install.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, and any equivalent replacement and modification or partial replacement which do not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
