[0011] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings needed to be used in the embodiments or prior art description. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor on the basis of these drawings.
[0012] Fig. 1 As shown in the utility model embodiment, the three-dimensional view of the tower crane arm frame connecting structure is shown.
[0013] Fig. 2 As shown in the utility model embodiment, the exploded view of the tower crane arm frame connecting structure is shown. DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0015] In combination Figs. 1-2 As shown, the tower crane arm frame connecting structure 100 comprises a first support 101 and a second support 102. The first support 101 comprises a first connecting arm 103 and a first supporting arm 104 connected at right angles. The second support 102 comprises a second connecting arm 105 and a second supporting arm 106 connected at right angles. The first supporting arm 104 and the second supporting arm 106 are in close contact with each other. A connecting column 107 is protruded on the end face of the first connecting arm 103. An axis hole 108 is recessed on the end face of the second connecting arm 105. The connecting column 107 is inserted into the axis hole 108. The end face of the first connecting arm 103 is in close contact with the end face of the second connecting arm 105. The two ends of the first connecting arm 103 are respectively provided with first pin holes 109. The two sides of the second connecting arm 105 are respectively provided with second pin holes 110. A pin 111 is inserted into the first pin hole 109 and the second pin hole 110 to be fixed. The end face of the first pin hole 109 is in close contact with the end face of the second pin hole 110. A first insertion slot 112 is formed on the end face of the first connecting arm 103. A second insertion slot 113 is formed on the end face of the second connecting arm 105.
