Abstract
The utility model discloses a davit fixing device comprising a davit bottom plate, two channels, a junction plate, anchor bolts and T-shaped bolts, wherein the davit bottom plate is fixedly connected with the davit; two channels are respectively welded on two ends of the junction plate; the anchor bolts penetrate through the junction plate to fix the junction plate on the top of a tunnel; the T-shaped bolts are installed in each channel in a sliding mode; and the davit bottom plate is fixedly connected with the free ends of the T-shaped bolts. According to the davit fixing device, load can be evenly distributed, and the davit can be flexibly adjusted.
Description
Technical field
The utility model relates to suspension contact system field in the tunnel, relates in particular to a kind of davit anchor fitting.
Background technology
In recent years, the China railways great-leap-forward development, high speed railway and railway line for passenger traffic will become the main direction of Future Development, and along with the raising of speed, the increasing of circuit labyrinth radius, the occupy ratio of tunnel in railway line constantly increases.
Because the restriction of tunnel inner height, the pillar of installing contact net adopts the davit that is lifted on tunnel top usually in the tunnel, and davit is to adopt crab-bolt to be fixed on tunnel top.And crab-bolt is after tunnel lining is built, by boring predetermined fixed at tunnel top.Yet on the one hand, because davit is fixed on tunnel top by crab-bolt, in case the stationkeeping of crab-bolt, the installation site of davit is just fixing, thereby is unfavorable for the accurate installation and the adjustment of contact system.On the other hand, because the discontinuity of single crab-bolt, thereby be difficult to satisfy stressed uniform requirement, and be unfavorable for controlling the requirement of construction error and tunnel machine construction reservation technology.
Therefore, be necessary to provide a kind of davit anchor fitting to overcome the problems referred to above.
The utility model content
The purpose of this utility model provide a kind of load is evenly distributed and can flexible the davit anchor fitting of davit.
To achieve these goals, the utility model provides a kind of davit anchor fitting, comprise the davit base plate of captiveing joint, two conduits, connecting panel, crab-bolt and T type bolts with davit, two described conduits are welded on the two ends of described connecting panel respectively, described crab-bolt is passed described connecting panel described connecting panel is fixed on tunnel top, described T type bolt is slidingly mounted in the every described conduit, and described davit base plate is captiveed joint with the free end of described T type bolt.
Particularly, described connecting panel is a band steel.
Particularly, described conduit comprises chute and a plurality of anchor fluke, and described anchor fluke is fixed on the top of described chute, and described T type bolt slides in described chute.
Particularly, the cross-sectional plane of described chute is " recessed " font, and described anchor fluke is " I " font.
Compared with prior art, on the one hand, be in the lining cutting top layer, to form the integral linear structure of strengthening owing to adopt the fixed form of conduit, thereby stressed even; On the other hand, owing to davit can slide by T type bolt, thereby help the accurate installation and the adjustment of davit in conduit.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
Description of drawings
Fig. 1 is the structural representation of an angle of the utility model davit anchor fitting.
Fig. 2 is the structural representation of another angle of the utility model davit anchor fitting.
Fig. 3 is the scheme of installation of connecting panel and conduit in the utility model davit anchor fitting.
Fig. 4 is the structural representation of conduit in the utility model davit anchor fitting.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label is represented similar elements in the accompanying drawing.
As Figure 1-3, present embodiment davit anchor fitting comprises the davit base plate (not shown) of captiveing joint with davit (not shown), two conduits 10, a plurality of connecting panel 11, a plurality of crab-bolt 12 and T type bolts 13.Two described conduits 10 weld with the two ends of a plurality of described connecting panels 11 respectively.Each described connecting panel 11 is provided with a pair of described crab-bolt 12 with the both sides of the weld of described conduit 10, and described crab-bolt 12 is passed described connecting panel 11 described connecting panel 11 is fixed on tunnel top.Described T type bolt 13 is slidingly mounted in the every described conduit 10, and described davit base plate is captiveed joint with the free end of described T type bolt 13.Preferably, described connecting panel 11 is a band steel.
As shown in Figure 4, described conduit 10 comprise cross-sectional plane be " recessed " font chute 101 and a plurality of being " I " font anchor fluke 102, described anchor fluke 102 is fixed on the top of described chute 101, described T type bolt 13 slides in described chute 101.
As from the foregoing, on the one hand, be in the lining cutting top layer, to form the integral linear structure of strengthening owing to adopt the fixed form of conduit, thereby stressed even; On the other hand, owing to davit can slide by T type bolt, thereby help the accurate installation and the adjustment of davit in conduit.
Abovely the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to essence of the present utility model in conjunction with most preferred embodiment.
