Embodiment
Progressive explanation is done to the present invention with reference to specific the drawings and specific embodiments.As shown in figure 1, a kind of friction energy dissipation
Device, including main body 1, the centre bore 14 that main body 1 runs through provided with left and right, are internally provided with the cavity 12 of upward opening, cavity
12 bottoms are provided with lug boss 11.Also include the column-shape rotator 2 being located in cavity 12, as shown in Fig. 2 the upper side wall of rotary body 2 is set
Have and lug boss 11 coordinates is recessed on portion 24, lower wall is provided with the lower recess 23 coordinated with lug boss 11, and rotary body 2 is close
The side in portion 24 is recessed on provided with the side opening 21 that left and right is run through vertically, when rotary body 2 rotates supreme recess 24 and lug boss
During 11 laminating, side opening 21 is overlapped with centre bore 14.For the ease of making rotary body 2 be rotated in the cavity 12 of main body 1, lug boss 11
Contact surface with recess is arcwall face, can so guarantee to rotate, be unlikely to stuck.
When installing steel wire rope, rotating rotary body 2 makes side opening 21 be overlapped with centre bore 14, i.e., the axis of holes is almost one
On bar straight line, now just steel wire rope 3 can be passed through centre bore 14 and side opening 21；Then rotary body 2 is rotated further by, makes 21 pairs of side opening
The lower recess 23 of face side is fitted with the lug boss 11 of the bottom of cavity 12, because side opening 21 is not on the axis of rotary body 2,
And be biased into being recessed on the side of portion 24, so now side opening 21 staggers with centre bore 14, steel wire rope 3 bends, such as Fig. 3 institutes
Show.Being recessed on portion 24 is used to position, convenient that side opening 21 and centre bore 14 align, and lower recess 23 is used to fix, and can make side opening
After 21 stagger with centre bore 14, rotary body 2 is fixed up with main body 1, and then safer fixation steel wire rope 3.
Steel wire rope 3 is being fixed on after bending between the cavity 12 of main body 1 and rotary body 2, to make steel wire rope 3 and main
Relative motion occurs for body 1 and rotary body 2, it is necessary to a relatively large startup power, to overcome steel wire rope 2 and main body 1 and rotation
Frictional force between swivel 2.The size of the startup power depends on the degree of roughness of material between steel wire rope 3 and main body 1 and rotary body 2
And space size, therefore can be by changing the degree of roughness of material and space between steel wire rope 3 and main body 1 and rotary body 2
Size come design it is different startup power friction energy dissipation devices, to meet the energy dissipating demand of different energy level protection networks.Meanwhile, steel wire
Rope 3 is bent, and the effect of fastening steel wire rope 3 can be reached during installation, without fixing steel wire rope again.
In use, main body 1 is fixed on the steel column of protection network, when protection network is by rock-fall impact, energy transmission is arrived
On steel wire rope 3 so that relative motion occurs for steel wire rope 3 and main body 1, the frictional force produced with relative motion offsets rock-fall impact
Energy, so as to reach effect of energy dissipating.Energy dissipator is after an energy dissipating is completed, and main body 1 and rotary body 2 are all without generation
Irreversible deformation, can be reused by reinstalling steel wire rope to realize.
Operate for convenience, rotating handles 22 is also welded with the front side wall of rotary body 2 or rear wall, rapid operation is convenient.
Or the jack that ripping bar is rotated for inserting is set on the front side wall of rotary body 2 or rear wall, rotation is inserted during installation in jack
Ripping bar is operated, and can play the effect same with rotating handles 22.
The main body 1 of energy dissipator can be arranged on the steel column 5 of protection network by the bolt 13 at two ends, can also be according to need
Ask, be directly welded on main body 1 on the steel column of protection network in advance.Main body 1 can be designed as to the cylinder that lower wall is provided with tack 15
Body, tack 15 is affixed on steel column when fixed, convenient and firm.
As shown in figure 4, energy dissipator 4 may be mounted at the steel column top passively netted, and passive protection net pull-up anchor line
With reference to realizing energy dissipating effect.
As shown in figure 5, energy dissipator 4 can also be arranged on every steel column of rigid grid, and the support of corresponding horizontal line
Rope is used in combination, and realizes energy dissipating effect.
