Specific embodiment
The present invention is described in further details below with reference to embodiment:
As shown in Figure 1, UHV transmission line lattice crossing frame, including pole standard knot 1, six lead to 2, standard section of tower crane 3, adapter 4 and terrace with edge 5.
It further include the pedestal of bottom as shown in Figure 1, UHV transmission line lattice crossing frame, pedestal can directly and tower The connection of standard knot 3 is hung, but in practice, bottom needs to set up cross bar, so connecting pedestal and six logical 2 using adapter 4, passed through Six logical 2 connect composition cross bar with pole standard knot 1;Need to connect standard section of tower crane 3, but six logical 2 and tower crane mark again on six logical 2 Quasi- section 3 cannot be directly connected to, so transferring using adapter 4, realize the knot for continuing that standard section of tower crane 3 is used on vertical pole Structure can be transferred using adapter 4 again when needing using pole standard knot 1, realized and constructed using standard section of tower crane 3 Vertical pole, the cancelled structure that cross bar is constructed using pole standard knot 1.
As shown in Fig. 2, the connecting hole for connecting pole standard knot 1 is equipped on six logical 2 six faces, at two It is connected between pole standard knot 1, pole standard knot 1 is made to form horizontal and vertical lattice.
As shown in figure 5, adapter 4 is equipped with for connecting the connecting hole of pole standard knot 1 and for connecting tower crane standard The connecting hole of section 3, adapter 4 make standard section of tower crane 3 and pole for being connected between standard section of tower crane 3 and pole standard knot 1 Standard knot 1 forms longitudinal bracket.
As shown in fig. 6, terrace with edge 5 is equipped with the pole standard knot 1 for connecting varying cross-section in top and bottom respectively Connecting hole makes pole standard knot 1 form longitudinal bracket for being connected between two pole standard knots 1.
As shown in Fig. 2, pole standard knot 1 has a multiple groups of varying cross-section, the side length of cross section therein include 500mm, 600mm,700mm,800mm,900mm,1000mm;When assembling lattice crossing frame, pole standard knot 1 is transversal from bottom to top Face is smaller and smaller, the self weight and windage of less crossing frame.
As shown in figure 3, standard section of tower crane 3 has a multiple groups of varying cross-section, the side length of cross section therein include 1450mm, 1650mm, equally when assembling lattice crossing frame, the cross section of standard section of tower crane 3 is smaller and smaller from bottom to top, less leap The self weight and windage of frame.
As shown in fig. 6, terrace with edge 5 includes two kinds of specifications, the connecting hole on one of terrace with edge 5 is for connecting cross section side length For the pole standard knot 1 of 800mm and 900mm, connecting hole on another terrace with edge 5 for connect cross section side length be 800mm and The pole standard knot 1 of 1000mm;When being able to use terrace with edge 5 and being attached pole standard knot 1, than more being closed with six logical by 2 structures Reason, is further reduced the self weight of crossing frame and windage.
As shown in figure 4, six logical 2 be cube structure, the connecting hole on six logical 2 is equipped with multiple groups and is respectively used to connect different cross The pole standard knot 1 in section;Six logical 2 include two kinds of specifications, and the connecting hole in one of which six logical 2 is for connecting cross section side length For the pole standard knot 1 of 500 mm, 600mm, 700mm, 800mm, the connecting hole that another kind six leads on 2 is for connecting cross section side The pole standard knot 1 of a length of 900mm, 1000mm;Can not be arranged on one six logical 2 can connect all specification pole standards The connecting hole of section 1, therefore the six logical 2 of the two kinds of specifications connection pole standard knot 1 for being separately connected each group is set, make six logical 2 and embraces The connecting portion reasonable mechanical of bar standard knot 1, guarantees the stability of crossing frame.
As shown in figure 5, adapter 4 includes pole standard knot interconnecting piece 4-1 and standard section of tower crane interconnecting piece 4-2, pole mark Quasi- section interconnecting piece 4-1 is equipped with the connecting hole for connecting pole standard knot 1, and standard section of tower crane interconnecting piece 4-2 is equipped with and is used for Connect the connecting hole of standard section of tower crane 3;Pole standard knot interconnecting piece 4-1 is the rectangular parallelepiped structure that upper and lower surface is square, tower It hangs there are four standard knot interconnecting piece 4-2 tools, is the height rectangular parallelepiped structure equal with pole standard knot interconnecting piece 4-1 height, Four standard section of tower crane interconnecting piece 4-2 are respectively from four angular pole standard knots of the facing of pole standard knot interconnecting piece 4-1 The opposite direction in the center of interconnecting piece 4-1 is extended, and adapter 4 can make connected pole standard knot 1 and tower crane standard Section 3 keeps center line identical, and corner relationship guarantees the firm and beautiful of crossing frame to correspondence.
As shown in Fig. 2, it is embracing for 1000mm that the connecting hole on pole standard knot interconnecting piece 4-1, which is used to connect cross section side length, Bar standard knot 1;Connecting hole on standard section of tower crane interconnecting piece 4-2 is equipped with two groups, wherein one group is for connecting cross section side length The standard section of tower crane 3 of 1450mm, another group for connecting the standard section of tower crane 3 that cross section side length is 1650mm.
As shown in figure 5, more reasonable in order to assemble the longitudinal carrier of crossing frame, standard section of tower crane 3 passes through 4 mistake of adapter When crossing to pole standard knot 1, preferably pole standard knot 1 uses cross section side length for the specification of 1000mm, therefore uses on adapter 4 Only it is arranged one group in the connecting hole of connection pole standard knot 1, in this way after being connect with pole standard knot 1, adapter 4 and pole mark The junction of quasi- section 1 is optimal the endurance of power, guarantees the firm of crossing frame.
As shown in figure 5, adapter 4 also needs to play the standard section of tower crane 3 of connection varying cross-section in applying in practice Effect, therefore common two groups are set by the connecting hole for being used to connect standard section of tower crane 3, it can be 1650mm's by cross section Standard section of tower crane is transitioned into the standard section of tower crane that cross section is 1450mm, and it is straight to avoid the standard section of tower crane that cross section is 1650mm The large span transition for being transitioned into the pole standard knot that cross section is 1000mm is connect, keeps the structure of crossing frame more reasonable.
