The invention provides a base and a crawler crane, relates to the technical field of cranes and aims at solving the technical problems of a complex structure and high manufacture cost of a base of anexisting crawler crane to a certain extent. The base is applied to the crawler crane and comprises a first supporting beam, a second supporting beam, a supporting plate and a base ring. The first supporting beam and the second supporting beam are oppositely arranged, the supporting plate is connected between the first supporting beam and the second supporting beam, and the base ring is arranged onthe supporting plate and used for installing a driving cab of the crawler crane.

The invention discloses a supporting base of a fish belly sill surrounding purlin. The supporting base comprises wide-flange H-shaped steel with the length of 100-150mm. The lower end of the H-shaped steel is welded to a square bottom plate which is provided with four flange holes. The four flange holes are distributed at four corners in a square shape. The side length of the square is 200mm. The diameter of each flange hole is 28mm. The upper end of the H-shaped steel is welded to a square connecting plate. Reinforcing plates are arranged in grooves in the two sides of the H-shaped steel. Three guiding plates are perpendicular to the square connecting plate and correspond to the reinforcing plates and wing plates on the two sides of the H-shaped steel respectively in an up-down mode. Two arch-shaped plates are arranged between the three guiding plates. The two arch-shaped sides of the arch-shaped plates are fixedly welded to the guiding plates on the two sides respectively. The two bottom sides of each arch-shaped plate are fixedly welded to the square connecting plate. A limiting inserting hole for a limiting blocking rod to be inserted in is formed in each of the two sides, above each arch-shaped plate, of each guiding plate. According to the technical scheme, assembling and disassembling are convenient, multi-time repeated using can be achieved, and the purpose that construction cost is saved, and construction is convenient is achieved.

The invention discloses a purlin surrounding assembly which comprises a lower chord beam component, a web member, first inclined struts and second inclined struts, wherein the lower chord beam component, the web member, the first inclined struts and the second inclined struts are made of H-shaped steel. Flange plates are fixed to the two ends of the lower chord beam component, grooves in the two sides of the lower chord beam component are provided with reinforcing plates, lug plates and drainage holes, and connecting holes are formed in outside flanks. Flange plates are welded to the two ends of the web member, one end of the web member is connected with inside flanks of the lower chord beam component through bolts, and grooves in the two sides of the web member are provided with reinforcing plates and drainage holes. According to the first inclined struts and the second inclined struts, the two end faces of each first inclined strut and the two end faces of each second inclined strut are 45-degree diagonal planes and welded to flange plates, one end of each first inclined strut and one end of each second inclined strut are connected with the web member through bolts, the other end of each first inclined strut and the other end of each second inclined strut are connected with the lower chord beam component through bolts, grooves in the two sides of each inclined strut are provided with lug plates and drainage holes, the length of each second inclined strut is 1 / 3 to 1 / 2 that of each first inclined strut, the number of the first inclined struts and the number of the second inclined struts are respectively two, and the first inclined struts and the second inclined struts are symmetrically arranged at the two sides of the web member. Webs of H-shaped steel of the lower chord beam component, the web member, the first inclined struts and the second inclined struts are located on the same plane. According to the technical scheme, the purlin surrounding assembly is convenient to disassemble and assemble and capable of being reused for multiple times and achieving the purposes of saving the construction cost and enabling construction to be convenient.

The invention discloses an air deflector director assembly tool set and an application method thereof. The air deflector director assembly tool set comprises a first spigot shaft, wherein both ends of the first spigot shaft are respectively provided with a rotary table which is perpendicular to the first spigot shaft; the first spigot shaft is provided with a plurality of positioning mechanisms for fixing air deflector gussets; and each positioning mechanism comprises a positioning baffle and a clamping baffle for clamping the air deflector gussets. The positions of mounting holes in the positioning baffle and clamping baffle on the first main shaft are adjusted to satisfy the assembly requirements of the envelope on the air deflector with different sectional dimensions and different lengths. The longer plate of the L-shaped positioning baffle is used for positioning the gussets, and the longer plate of the clamping baffle and the longer plate of the positioning baffle are arranged oppositely to clamp the gussets and are connected through a bolt, thereby being flexible and convenient to disassemble. In the envelope process, the rotary tables can be overturned to overturn the assembly tool set without manually adjusting the position of the assembly tool set, thereby effectively avoiding scratching the aluminum product.
