But for rigid suspension system, due to the particularity of its structure, the direct installation which can not meet it is fixed, need a kind of simple structure to realize the fixed installation of rigid suspension system on annular pre-buried channel flow.
Summary of the invention
The purpose of this utility model is to provide the rigid suspended fastening devices of a kind of annular pre-buried channel flow, for pre-buried channel flow annular in tunnel, by increasing the angular adjustment amount of system self, realizes the switching bolt of suspention channel-section steel and two forming V-shapes to fix.
The technical scheme that the utility model adopts is:
The rigid suspended fastening devices of a kind of annular pre-buried channel flow, is characterized in that:
Comprise the suspention channel-section steel of strip, in the middle part of suspention channel-section steel, be fixed with rigid suspended insulator and collector-gang positioning lead clip downwards;
A switching bolt is fixed on each via upper and lower two groups of angle regulating pad block assemblies in suspention channel-section steel two ends;
Angle between both sides switching bolt is V-shaped, and the set bolt that top carries with annular pre-buried channel flow is connected.
Described angle regulating pad block assembly comprises a hemispheric convex surface cushion block and a concave surface cushion block covered on convex surface cushion block sphere;
In two groups of angle regulating pad block assemblies that upper and lower both sides, suspention channel-section steel end are arranged, the convex surface cushion block of upside angle regulating pad block assembly under, concave surface cushion block upper, the convex surface cushion block of downside angle regulating pad block assembly upper, concave surface cushion block under.
Screw rod in described switching bolt points to the annular pre-buried channel flow center of circle;
Often organize on the convex surface cushion block of angle regulating pad block assembly and concave surface cushion block and be provided with the through hole coordinating switching bolt screw rod direction.
The through hole of the through hole and two ends fixed angle adjusting pad block assembly of fixing rigid suspended insulator and collector-gang positioning lead clip in the middle part of described suspention channel-section steel is slotted hole.
Described suspention channel-section steel stage casing arranges the projection upwards for adapting to low headroom tunnel.
Angle regulating pad block assembly is tightened up by pad and hold-down nut by the screw rod bottom of switching bolt.
The utility model has the following advantages:
The utility model provides a kind of fixed, easy-to-install rigid suspension system fixed form, to be fixed in tunnel on annular pre-buried channel flow by special bolt, screw rod is extended, for being fixedly connected with other parts to annular direction, the pre-buried channel flow center of circle, place.Main body is channel-section steel structure, and two ends have for being connected with switching bolt and the elongated hole that tilts of the bolt certain angle that allows to transfer, and centre has can at the large-scale elongated hole of internal fixtion insulator in a big way.Often overlap angle regulating pad block assembly by the cushion block of semicircle convex surface with the cushion block of semicircular concave is supporting forms, used by upper and lower two combination accessories, the installation of bolt on non-perpendicular work plane can be realized fix, solve the problem that connecting bolt and suspention channel-section steel stationary plane out of plumb cannot be fastening.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The rigid suspended fastening devices of one annular pre-buried channel flow that the utility model relates to, comprises the suspention channel-section steel 1 of strip, is fixed with rigid suspended insulator 2 and collector-gang positioning lead clip 3 downwards in the middle part of suspention channel-section steel 1.A switching bolt 4 is fixed on each via upper and lower two groups of angle regulating pad block assemblies 5 in suspention channel-section steel 1 two ends, symmetrical.Angle between both sides switching bolt 4 is V-shaped, and the set bolt that top carries with annular pre-buried channel flow is connected.
Described angle regulating pad block assembly 5 comprises a hemispheric convex surface cushion block and a concave surface cushion block covered on convex surface cushion block sphere.In two groups of angle regulating pad block assemblies 5 that upper and lower both sides, suspention channel-section steel 1 end are arranged, the convex surface cushion block of upside angle regulating pad block assembly 5 under, concave surface cushion block upper, the convex surface cushion block of downside angle regulating pad block assembly 5 upper, concave surface cushion block under.Screw rod in described switching bolt 4 points to the annular pre-buried channel flow center of circle; Often organize on the convex surface cushion block of angle regulating pad block assembly 5 and concave surface cushion block and be provided with the through hole coordinating switching bolt 4 screw rod direction.Angle regulating pad block assembly 5 is tightened up by pad 6 and hold-down nut 7 by the screw rod bottom of switching bolt 4.The design of angle regulating pad block assembly 5 achieves the installation of switching bolt 4 on non-perpendicular work plane and fixes.
