The two connecting faces 30 can be welded to the two main chords respectively to form two integral structures, or can be detachably coupled to the main chord. The main chord includes two left main chords 40 and two right main chords 50, the climbing surface 10 is disposed between the two left main chords 40, and the introduction surface 20 is disposed between the two right main chords 50. When the tower crane is in the transport state, the climbing surface 10, the introduction surface 20 and the two connecting surfaces 30 are separately transported, which can effectively utilize the transportation space and reduce the space occupation of the integral structure, thereby reducing transportation costs. When the tower crane climbing frame needs to be assembled at the construction site, the climbing surface 10, the introduction surface 20 and the two connecting surfaces 30 are assembled, the assembly speed can be accelerated, and the parts caused by excessive assembly parts are not easily recognized, and the installation is inconvenient. The problem is that the working faces (ie, the climbing surface 10, the introduction surface 20 and the two connecting surfaces 30) can be directly combined, which reduces the assembly steps and improves the assembly efficiency. Referring to Figures 4 to 7, the tower crane can include two integral connecting faces 30, and a climbing face 10 and an incoming face 20 having a sheet structure, two left main chords 40 and two right The main chords 50 are respectively located on both sides of the two connecting faces 30, and the climbing face 10 and the introduction face 20 are fixedly coupled to the two left main chords 40 and the two right main chords 50. When disassembling, the climbing surface 10 and the introduction surface 20 are removed from the main chord, and then loaded and transported. Since the four working surfaces are split into a piece structure, they can be stacked to reduce the tower crane. Space occupation during transportation. When assembling, the two connecting faces 30 are first positioned, and then the climbing face 10 and the leading face 20 of the sheet structure are installed between the left main chord 40 and the right main chord 50 to complete the tower crane climbing frame. Assembly. Since the two connecting faces 30 are of a unitary structure, it is more convenient to mount and position the climbing face 10 and the lead-in face 20 of the chip structure. The sheet structure of the climbing surface 10 of the tower crane may be an integral sheet structure detachably disposed between the two left main chords 40, or may include a plurality of left main chords arranged in sequence. A slice structure between 40. In the present embodiment, the climbing surface 10 includes a second sheet structure 12, a third sheet structure 13, and a fourth portion that are detachably disposed between the two left main chords 40 in order from the top of the climbing surface 10. The sheet structure 14 and the first sheet structure 11, wherein the fourth sheet structure 14 comprises a connecting beam 16 disposed at the bottom, and the fourth sheet structure 14 and the first sheet structure 11 are passed between the two webs 15 connection. The upper ends of the two webs 15 are connected to the middle of the connecting beam 16, and the lower ends are respectively connected to the two top connecting plates 111 of the first sheet structure 11. The arrangement of such a structure is determined by the manner in which the first sheet structure 11 is disposed. The first sheet structure 11 is disposed outside the two left main chords 40, so that in order to secure the connection of the first sheet structure 11 and the fourth sheet structure 14, a transition is made between the two webs 15 therebetween Connections enable better connection. The plurality of sheet structures that make up the climbing surface 10 can also be other numbers of sheet structures. Each of the sheet structures includes at least one crossbar and two diagonal rods attached to the crossbar to form a triangular joint structure to ensure a stable connection of the respective sheet structures of the climbing frame. The introduction face 20 includes a fifth sheet structure 23 and a sixth sheet structure 24 respectively disposed at both ends of the two right main chords 50, and an introduction inlet between the fifth sheet structure 23 and the sixth sheet structure 24. twenty one. The fifth sheet structure 23 is located above and the sixth sheet structure 24 is located below. Both sides of the fifth sheet structure 23 and the sixth sheet structure 24 are detachably coupled to the two right main chords 50. Import 21 is used to introduce a new standard section. The right main chord 50 on both sides of the position where the inlet 21 is located is detachably provided with a connecting rod 22, and the two connecting rods 22 are diagonally disposed at the inlet 21 . The lower ends of the two connecting rods 22 are respectively connected to the two right main chords 50 by adjusting bolts, and the length of the connecting rods 22 can be adjusted by the adjusting bolts, thereby adjusting the structural strength of the introduction surface 20 of the inlet 21, enhancing the position Structural strength. When it is necessary to introduce the standard section, only the two connecting rods 22 need to be removed, and the standard section can be introduced from the inlet 21, which is simple and convenient to operate. When the two attachment faces 30 are detachably coupled to the main chord, the attachment face 30 can include at least one set of sheet structures that are removably disposed on the main chord. In this way, when the connection is made, the main chord can be removed and transported separately, and the sheet structure of the four working faces can be loaded and transported, which can greatly reduce the transportation space and reduce the transportation cost. In the assembly, since the chip structure is different, and the shape of each chip structure is different, it is convenient to determine the mounting position on the main chord according to the shape of each chip structure, which is easy to identify and install. The operation is simple and convenient, and has the advantages of small transportation space and high assembly efficiency. In accordance with an embodiment of the present invention, a tower crane includes a standard section and a tower crane that is nested outside the standard section, the tower crane being any of the tower cranes described above. From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: The tower crane includes a climbing surface, an introduction surface, and two connection surfaces connecting the climbing surface and the introduction surface, the climbing surface, and the introduction surface. And the two connecting faces are connected by a main chord, the climbing face and the introducing face each comprise at least one set of sheet structure, the sheet structure is integral and detachably connected to the main chord. When the tower crane climbing frame needs to be transported, the tower crane climbing frame can be divided into a plurality of chip structures according to each surface, and each chip structure takes up less space, thereby reducing transportation space occupation and reducing transportation cost. When the tower crane is assembled, the four faces can be assembled directly, which avoids the problem that the assembly of multiple parts is difficult to identify, and the assembly is troublesome, and the assembly efficiency can be improved. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
