The important component hung plays a very important role in whole tower crane.When connecting two section standard section of tower crane, first will
Upper and lower two sections standard knot stacks, and couples the stepped tooth on corresponding each main chord completely with dovetail groove, then with
The connector sleeve of upper and lower corresponding is threaded togather and is tightened by the bolt being threadedly engaged, and is consolidated to upper and lower two sections standard knot
It is fixed.
But set on every main chord there are two connector sleeve, fixation is tightened by bolt one by one, when being dismantled
When also by bolt one by one back-out come, time-consuming troublesome in poeration.
Utility model content
The purpose of this utility model is in view of the above problems, providing a kind of building tower crane standard knot, and structure is simple,
It overlaps convenient and efficient, the assembling of standard knot can be completed in the case where not using bolt, improve efficiency.
In order to achieve the above object, the technical solution adopted in the utility model is: it includes main chord, cross bar and brace,
It is characterized in that, the bottom of main chord is provided with insertion end, and the slot to match with insertion end is provided at the top of main chord, main
It is provided with fixed block on the outside of the upper end of chord member, sliding slot is provided between fixed block and main chord lateral wall, is provided with cunning in sliding slot
Block is provided with the straight-line groove communicated between slot and sliding slot, slot is provided with the first pin hole in the opposite side for being located at straight-line groove, is inserted into
The lower end at end is provided with the second pin hole, and main chord lower end inside is fixedly installed bracket, guide rod, guiding are laterally interted on bracket
Bar is fixedly connected with connecting plate, and the bottom of connecting plate is fixedly connected with bolt, the hinged anti-drop block in the end of bolt.
Further, bracket is zigzag structure, and by being welded and fixed between bracket and main chord.
Further, fixed block is weldingly fixed on the outside of main chord.
Further, anti-drop block is rectangular parallelepiped structure.
The utility model has the beneficial effects that the utility model provides a kind of building tower crane standard knot, structure letter
Single, overlap joint is convenient and efficient, and the assembling of standard knot can be rapidly completed in the case where not using bolt, improve efficiency.
Detailed description of the invention

Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As Figure 1-Figure 2, the specific structure of the utility model are as follows: it includes main chord 7, cross bar 14 and brace 15,
It is characterized in that, the bottom of main chord 7 is provided with insertion end 6, and the top of main chord 7 is provided with the slot to match with insertion end 6
The upper end outside in hole 12, main chord 7 is provided with fixed block 8, is provided with sliding slot 9 between 7 lateral wall of fixed block 8 and main chord, sliding
It is provided with sliding block 10 in slot 9, the straight-line groove 11 communicated is provided between slot 12 and sliding slot 9, slot 12 is being located at straight-line groove 11
Opposite side be provided with the first pin hole 13, the lower end of insertion end 6 is provided with the second pin hole 16, the fixed setting of 7 lower end inside of main chord
There is bracket 2, laterally interts guide rod 1 on bracket 2, guide rod 1 is fixedly connected with connecting plate 3, and the bottom of connecting plate 3 is fixedly connected
Bolt 4, the hinged anti-drop block 5 in the end of bolt 4.
Preferably, bracket 2 is zigzag structure, and by being welded and fixed between bracket 2 and main chord 7.
