[detailed description of the invention]
For understanding the present invention better, below with reference to accompanying drawing and instantiation, invention is described in detail.
When designing support, mainly follow safety, economic, feasible principle, what time following the design focal point of power grid construction highway crossing support of the present invention considered:
First aspect, support needs to set up in the middle of speedway, on speedway, place is limited, car is many, use lifting appliance auxiliary set up unrealistic, therefore the setting up mainly to rely on and manually complete of support, this just requires that support all parts weight can not be too large, and artificial installation also should be simply light.
Second aspect, support should be able to ensure the minimum Clearance requirement of speedway (such as, 5m), and can bear the total weight (such as, 60kg) when insulating cord relaxes completely, and covers the width (such as, 30m) of crossing frame comprehensively.
Comprehensive above several aspect, support of the present invention adopts the mode of the rope connected between column and column to arrange support, and detailed construction hereafter will describe in detail.
Power grid construction highway crossing support of the present invention is arranged on the below of highway crossing frame, for carrying the rope on highway crossing frame, preventing it from dropping and to threaten or potential safety hazard to highway communication.Incorporated by reference to consulting Fig. 1 and Fig. 2, the power grid construction of the present invention preferred embodiment of highway crossing support comprises column 10, reinforces the drag-line 20 of column 10 and connect the carrying rope 30 of column 10.Power grid construction highway crossing support is equidistantly distributed by some columns 10.Such as, the power grid construction highway crossing support shown in Fig. 1 has five columns 10, and column 10 launches along highway direction according to the mode of column interval 7.5m adjacent between two.
Column 10 comprises base 12, strut 14 and top cylinder 16, as shown in Figure 2.Base 12 supports on the ground, as the mount pad of strut 14.Strut 14 lower end is arranged on base 12.Top cylinder 16 is arranged on the upper end of strut 14.The whole height of column 10 is 9m, can adapt to the height of crossing frame.In order to make the base 12 of column more firm, the both sides of base 12 have additional balancing weight 13.Balancing weight 13 pushes down base 12 from both sides, makes column 10 entirety fixing more steady.The length of strut 14 is the height of column substantially, and namely the length of strut 14 is about 9m.Strut 14 is installed on an every root strut 14 of bracing cable clamp 15(every 3m and has two bracing cable clamps 15), for stay guy 20 before strut 14 adjacent between two.In view of the feature of glass-reinforced plastic material density little (only for ordinary carbon steel 1/4 ~ 1/5), mechanical strength high (stretching of some epoxy FRP, bending and compressive strength all can reach 500Mpa), adopt fiber glass epoxy tubing article as strut 14.Consider the reason of convenient economy, base 12 adopts seamless steel pipe and square plate welding, and top cylinder 16 adopts seamless steel pipe welded pulley to form.
Carry out connecting (that is, the drag-line 20 between two bracing cable clamps 15 on adjacent between two column 10 forms " X " shape) with cross one another form between two bracing cable clamps 15 of drag-line 20 on column 10 adjacent between two.Drag-line 20 on two columns 10 on most side outside two bracing cable clamps 15 anchors to ground (as shown in fig. 1).
Carrying rope 30 is in the mode overhang downwards by connecting the top cylinder 16 of every two adjacent upright posts 10 upper ends in turn, and carrying rope 30 overhangs lowest part should higher than drag-line (namely carry between rope 30 and drag-line 20 and any interference does not occur).According to actual conditions, the Di Nima rope conduct carrying rope 30 adopting specific strength high, with load capacity.
In the above-described embodiments, the quantity of column is 5, is spaced apart 7.5m between adjacent upright posts, and the height of column is 9m, and it is applicable to the crossing frame that width is 30m.In other preferred embodiment, the number of column, spacing and height can correspondingly adjust, and the quantity of column and interval can adjust according to the width of crossing frame, the height of column lower than crossing frame height and higher than the minimum Clearance requirement of highway.Such as, the quantity of column can be 7, is spaced apart 7m between column, and applicable width is the crossing frame of 42m.The quantity of column at least 2, can reach 8.
When the rope in crossing frame for some reason lax drop on power grid construction highway crossing support time, lax rope will be propped up and stop it to fall further by the carrying rope 30 above support, avoids accident.20 rope actings in conjunction are drawn in the anchoring at the balancing weight 13 on base 12, the intersection drag-line 20 between strut 14 and two ends, increase support integral rigidity, prevent support to be out of shape because of load-bearing.
Compared to prior art, power grid construction highway crossing support of the present invention at least has the following advantages:
(1) this support mainly adopts the material that the specific strengths such as glass fiber reinforced plastic, Di Nima rope are high, reduces weight as far as possible, facilitate the transport under mal-condition and installation under the condition meeting requirement of strength.
(2) structurally, this support adopts removably, and the weight and volume after fractionation all controls within zone of reasonableness, and coupling part mainly adopts the mode of sleeve connection and pin joint, convenient on-the-spot artificial mounting or dismounting.
(3) this support is except further strengthening except carrying for carrying out highway crossing frame, also can be applicable to the occasion that other need to support.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
