The specific embodiment
Hereinafter will and combine embodiment to specify the utility model with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
As shown in Figure 1, according to the embodiment of the utility model, the main structure of integral type standard knot comprises eight horizontal web members 10, eight diagonal web members 20, four main chords 30, cat ladder 70 and integral type platforms 60.Eight horizontal web members 10, eight diagonal web members 20 and four main chords 30 surround the shaped as frame structure.
Cat ladder 70 is fixedly installed on the horizontal web member 10 of one side, is equipped with four railings 71 in the outer periphery of cat ladder 70, and cat ladder 70 peripheries are formed go along with sb. to guard him, the safety of protection staff when climbing cat ladder 70, and strengthen the Joint strenght between diagonal web member 20 and the main chord 30.
The standard knot of each face comprises two diagonal web members 20.First end of two diagonal web members 20 is connected the middle part of main chord 30, and second end is connected to the upper end or the bottom of main chord 30, makes and forms K shape structure between two diagonal web members 20 and the main chord 30.Be provided with a horizontal web member 10 in the centre of two diagonal web members 20, make between diagonal web member 20, horizontal web member 10 and the main chord 30 triangular structure that forms a plurality of good stabilities, effectively strengthened the structure steadiness of integral type standard knot.
Please combine referring to shown in Figure 2, the horizontal web member 10 of integral type standard knot upper end intersects with the diagonal web member 20 and the center of the upper end of main chord 30.Intersecting on the sidewalls of sides with horizontal web member 10 and diagonal web member 20 of main chord 30 is set with rebound 40, and horizontal web member 10 is fixedly connected on the rebound 40 with diagonal web member 20.Through rebound 40 is set; The application force of horizontal web member 10 and diagonal web member 20 is acted directly on the rebound 40, rather than on the main chord 30, and rebound 40 has also strengthened the structural strength of the end bearing structure of main chord 30; Improved the crushing resistance of main chord 30; Thereby improved the crushing resistance of integral type standard knot, simple in structure, stability is better.
Please combine referring to Fig. 3 and shown in Figure 4; Rebound 40 is the tabular structure of oblong; Midway location at rebound 40 is provided with countersunk head dimple 41, and the bearing of trend of countersunk head dimple 41 is provided with pore 42, and the space of countersunk head dimple 41 with the outside of rebound 42 is connected.
Also include the cross joint 50 of pin shaft hole in the upper end of the main chord 30 of integral type standard knot and the chord member structure of bottom.First end of the cross joint 50 of pin shaft hole is arranged on an end of a joint integral type standard knot, and second end is used for being connected with another joint integral type standard knot.The two ends of the cross joint 50 of pin shaft hole include the pin shaft hole 52 that two right-angled crossings are provided with respectively; The pin shaft hole 52 of two right-angled crossing settings of first end lays respectively at the diverse location of the axial direction of the cross joint 50 of pin shaft hole; One of them pin shaft hole 52 is towards rebound 40; And the countersunk head dimple 41 corresponding settings with rebound 40 are positioned on the bearing of trend of pin shaft hole 52 the countersunk head dimple 41 of rebound 40.
Connect through being connected bearing pin 51 between the cross joint 50 of pin shaft hole and the main chord 30.Countersunk head dimple 41, the second ends that first end of connection bearing pin 51 is positioned at rebound 40 are positioned on the lateral wall of main chord 30.The second end external fixation that connects bearing pin 51 is provided with shrouding 32, to connecting the location that bearing pin 51 forms axial direction.Countersunk head dimple 41 cooperates with shrouding 32, and connection bearing pin 51 is fixedly installed in the main chord 30, and the cross joint 50 of pin shaft hole is fixed together with main chord 30.
Because the existence of rebound 40 makes horizontal web member 10 can not interfere with the bearing pin 51 that is connected of the cross joint 50 of pin shaft hole with diagonal web member 20, the cross joint 50 of pin shaft hole is set to possibility on main chord 30.Use the cross joint 50 of pin shaft hole to realize the connection between the integral type standard knot, improved the torsional strength of integral type standard knot effectively, load-carrying capacity is good, and is simple in structure, and more reasonable stress is installed more convenient.
Also setover on the outer wall of the end of main chord 30 brace panel 31 is arranged; Brace panel 31 is positioned on the side of diagonal web member 20 and the main chord 30 at main chord 30 connection location places; And move to a lateral deviation of main chord 30; Thereby the track adjusting wheel on the frame of avoiding climbing, make climb frame not can and brace panel 31 between interfere.The structure that is provided with main chord 30 of brace panel 31 plays booster action, has further improved the load-carrying capacity and the anti-extrusion ability of main chord 30.The corresponding position that connects bearing pin 51 installations is a through-hole structure on the brace panel 31, and connection bearing pin 51 is located on the brace panel 31.Shrouding 32 envelopes are located at the outside of brace panel 31, and connection bearing pin 51 is fixedly installed in the main chord 30.
When the integral type standard knot is installed, pass main chord 30 and the cross joint 50 of inboard pin shaft hole to the connection bearing pin 51 of the cross joint 50 of pin shaft hole earlier, seal connecting bearing pin 51 1 ends with shrouding 32 then; Cover connection bearing pin 51 with rebound 40 again, let connection bearing pin 51 penetrate countersunk head dimple 41, weld rebound 40 and main chord 30 according to the design size requirement, this moment, countersunk head dimple 41 interior air pressurizeds passed through pore 42 discharges; Weld horizontal web member between per two main chords 30 10 and diagonal web member 20 then, thereby constitute an integral type standard knot main structure; All install cat ladder 70 and railing 71 at last, form simple in structure a, reasonable stress, easy for installation, integral type standard knot that hommization is high.
From above description; Can find out; The utility model the above embodiments have realized following technique effect: the integral type standard knot comprises horizontal web member, diagonal web member and main chord, is set with rebound on the sidewall of main chord, and horizontal web member and diagonal web member are fixedly connected on the rebound.Through the setting of rebound, make horizontal web member and diagonal web member not direct connection on main chord, strengthened the structural strength of main chord through rebound; Improved the anti-extrusion performance of integral type standard knot; Simple in structure, resistance to overturning is good, effectively improves the safety and the reliability of tower machine.The integral type standard knot comprises that also first end is arranged on the cross joint of pin shaft hole in the main chord, and the cross joint of pin shaft hole is connected with main chord through connecting bearing pin.Through the cross joint of pin shaft hole is arranged in the main chord, realize the connection between the more piece integral type standard knot, effectively improved the torsional strength of integral type standard knot, improve the resistance to overturning of standard knot.The outer wall upper offset of the end of main chord has brace panel, connects bearing pin and passes the brace panel setting.Through a plurality of brace panels are set on the outer wall of main chord end, further improved the structural strength of main chord end, improved the anti-extrusion performance of standard knot.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
