Description
Technical field
The utility model relates to subway tunnel equipment, and in particular to a kind of extension fixed structure of Metro Cable gantry.
Background technique
To each, cable in national standard " GB50168-2006 erection works of electrical installations code for construction and acceptance of cable levels "
Horizontal distance between holding a little is made that specific requirement: mesolow cable in addition to full-plastic and control cable respectively support a little between water
Flat distance is 800mm；Horizontal distance between 35kV and the above high-tension cable are respectively supported a little is 1500mm, and part subway tunnel is being set
The versatility of cable testing bridge is not considered in timing, and original is designed as the cable testing bridge of 35kV and the above high-tension cable cabling, if you need to change
When for mesolow cable and control cable routing, gantry, which has to pass through necessary be transformed, can just meet the requirement of GB50168.
But the installation foundation of cable testing bridge, it is just to be embedded on tunnel inner wall in constructing tunnel, such as by former peace
Dress mode need to be related to the civil construction in tunnel, long in time limit, big to original line influence, therefore, it is necessary to design a kind of new
Fixed structure, the needs being transformed with appropriate cable gantry.
Summary of the invention
In view of the above, the purpose of this utility model is to provide a kind of extension fixed structure of Metro Cable gantry,
The expansion of gantry is fixed using simple mode on the basis of not breathing out fragrant slot transformation to former tunnel for the extension fixed form
Exhibition, meets it each to cable in national standard " GB50168-2006 erection works of electrical installations code for construction and acceptance of cable levels "
Support the requirement in the horizontal distance between point.
The technical solution adopted in the utility model is as follows: a kind of extension fixed structure of Metro Cable gantry, including crossbearer,
Vertical frame, the molding fixed block of structural carbon steel mould punching, the crossbearer use carbon constructional steel plate extrusion forming, the end of crossbearer
End begins with c-type expansion slot, and the longitudinally disposed built-in groove being recessed inwardly is offered on the vertical frame, and two crossbearers are solid by one
Determine block to connect and on the built-in groove that is fixed on vertical frame using standard component, the fixed block is square structure, and edge has
Take stamping forming raised tight locking button.
Further, the standard component includes T-bolt, plain cushion, spring washer and nut.
Further, the c-type expansion slot is double-layer structure, and upper layer has semi-circular notch, and two pieces c-type expansion slot is spelled
Circular hole is formed after dress, the lower layer of c-type expansion slot is provided with rectangular slot, and the tight locking button of two sides is caught in rectangle above and below the fixed block
In slot, bayonet is provided in c-type expansion slot, the c-type expansion slot is stuck on built-in groove, and the tight locking button at left and right sides of fixed block is caught in
Into bayonet.
Compared with the prior art, crossbearer can be mounted on arbitrarily by the utility model by setting c-type expansion slot and fixed block
On the vertical frame of height, realizes on the basis of not breathing out fragrant slot transformation to former tunnel, gantry is fixed using simple mode
Extension, meets it right in Kunming Market " GB50168-2016 erection works of electrical installations code for construction and acceptance of cable levels "
Cable respectively support a little between distance in requirement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the extension fixed structure of Metro Cable gantry described in the utility model；
Fig. 2 is the portion attached drawing 1A schematic enlarged-scale view；
Fig. 3 is the structural schematic diagram of c-type expansion slot shown in attached drawing 1；

Specific embodiment
In order to describe the technical content, the structural feature, the achieved object and the effect of this invention in detail, below in conjunction with embodiment
And attached drawing is cooperated to be explained in detail.
As Figure 1-Figure 4, a kind of extension fixed structure of Metro Cable gantry, including crossbearer 2, vertical frame 4, carbon structure
The stamping forming fixed block 1 of steel mold, the crossbearer 2 use carbon constructional steel plate extrusion forming, and the end of crossbearer 2 begins with C
Type expansion slot 21, the longitudinally disposed built-in groove 41 being recessed inwardly is offered on the vertical frame 4, and two crossbearers 3 are fixed by one
Block 1 is connected and is fixed on the built-in groove 41 on vertical frame 4 using standard component, and the standard component includes T-bolt, plain cushion, spring washer
And two crossbearers 2 can be connected to arbitrary height position by longitudinally disposed built-in groove 41 by nut, realize the height of crossbearer 2
Degree adjustment.
The fixed block 1 is square structure for fixing two crossbearers 2, fixed block 1, and edge, which is taken, to be struck out
The raised tight locking button 11 of type, is provided with bayonet 22 in c-type expansion slot 21, and c-type expansion slot 21 is stuck on built-in groove 41 when installation, left and right
