Description
Technical field
The utility model relates to a kind of road bar, specifically relates to a kind of road indicating lamp bar.
Background technology
Traffic lights are the critical facilitys in traffic signals commander, and be widely used in cross-road, bend, bridge etc. have Dangerous Area conductor driver or the pedestrian traffic of potential safety hazard, promote to have a good transport and communication network, and avoid traffic accident and contingency generation.
Along with the quickening of urban construction, urban road broadens, and stop-light bar needs constantly to lengthen along with the increase of road width, to ensure that indicator lamp is arranged at directly over road.Conventional traffic instruction lamp stand, generally includes a support perpendicular to the ground and a crossbeam parallel to the ground.Support is the equilateral polygon section steel pipe pole rolled by steel plate, is fixed on the basis on ground by Flange joint of putting more energy into; Crossbeam is the steel pipe thinner than support, and one end is welded or is fixedly attached to cradle top by adding stiffening flange, and the other end is laterally unsettled in urban road overhead.Crossbeam is fixed on support by welding or adding stiffening flange, and form typical rigid frame cantilever design, beam-end and cradle top side are rigidly connected.This cantilever rigid frame structure is generally controlled by moment of flexure, and for stop-light bar, stop-light gravity is certain, and the arm of force is very large, and cause moment very large, crossbeam root and support bear very large moment of flexure, and then needs crossbeam and support Design to obtain very sturdy; The crossbeam that this design is heavy, had both increased gravity laod and had turn increased the area that keeps out the wind, and made moment of flexure and moment of torsion increase further.The increase of crossbeam load directly results in again the increase of support specification, thus causes this design to enter vicious circle.This structure stress unreasonable distribution, structure load is large, and rod member specification is large, causes the waste of material to a certain extent.In addition, crossbeam and the support overwhelming majority are by Flange joint of putting more energy into.Add stiffening flange to need to weld multiple ribbed stiffener and auger shell keyhole, with crossbeam by solder design, welded by connecting plate polylith with support.Weld seam quantity is many, expends man-hour long, and weldquality not easily ensures, processing cost is high.The crossbeam of tradition lamp stand, because heavy, in order to weight reduction as far as possible, is usually processed into cone barrel, and the free end that moment of flexure is little is very thin, and connection bracket end moment of flexure is very large, needs very thick size, processed complex.
Summary of the invention
For overcoming the above problems, the utility model provides Novel traffic light bar.
The purpose of this utility model is realized by following technical proposals:
A kind of instruction lamp stand, described lamp stand comprises support and crossbeam; Described support is perpendicular to the ground, and described crossbeam is parallel to the ground; Support is provided with pin joint apart from 2/3-3/4 place, ground, and beam-ends is also provided with pin joint; Pin joint on support and the pin joint of crossbeam hinged; Strained by bracing wire between in the middle part of cradle top and crossbeam.
Support is lower large little conical rod.
Crossbeam is cylindric bar.
Be provided with stay thimble in the middle part of cradle top and crossbeam, bracing wire tension is between two stay thimbles.
At the free end of crossbeam, indicator lamp is installed.
Crossbeam bottom surface is provided with the rectangular sheet vertical with horizontal direction; Rectangular sheet is provided with base vertical in two parallel sheet isosceles triangles of horizontal direction, and triangle is provided with hole.
Crossbeam pin joint be a base vertical in ground, the isosceles triangle laminated structure with crossbeam axis coaxle, which is provided with hole.
Crossbeam pin joint is the isosceles triangle that base vertical is fitted in horizontal direction and with section of beam; Isosceles triangle is provided with the groove perpendicular to horizontal direction, and it is two parallel sheet isosceles triangles that this groove splits described triangle, and fluting extends to crossbeam 1/5-1/4 place.
With prior art ratio, the stop-light bar that the utility model provides, has following excellent effect:
1, novel lamp stand has taken into full account loading characteristic and the processing technology of cantilever traffic lamp stand, and change the connected mode arranging structure, structural configuration is succinctly reasonable.
2, the structural change transmission of power of this instruction lamp stand, improves structural load and distributes, optimize the carrying method of salary distribution, improve structure stress.External load and rod member deadweight by rod member originally experience curved bear to change into controlled by a bracing wire tension.Remarkable to improve structure entirety stressed, reduces the dimensions of component, reduces steel using amount.
3, the deadweight of the utility model crossbeam is much smaller than traditional crossbeam, and also make support specification reduce, therefore this lamp stand advantage is more obvious simultaneously.
4, the utility model crossbeam free end moment of flexure is very little, and hinged end moment of flexure is zero, and therefore specification is very little, and equal diameter steel pipe can meet the demands as its crossbeam, processes easy.
5, because the change of crossbeam specification and its connected mode, reduce the use of a large amount of stiffener, thus reduce the quantity of weld seam and produce welding residual stress thus, improve the stress of connected node.
6, reduce the use of stiffener, reduce weld seam quantity, reduce the front face area of node, decrease wind load.
7, beam height is adjustable.If run into special circumstances, such as Overheight Vehicles pass through, and unclamp bracing wire, upwards raise crossbeam, and traditional rod cannot be accomplished.
8, decrease labor content, reduce cost of labor and processing cost.

Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in further detail:
The utility model provides a kind of instruction lamp stand, adopts support 1 and crossbeam 2 two main members, but connected mode to change peg type into hinged, crossbeam 2 is drawn a bracing wire 3 simultaneously and is connected to support 1 top.
See Fig. 1, the utility model one instruction lamp stand, is formed by perpendicular to the support 1 on ground and the crossbeam 2 of placement parallel to the ground; Support 1 is lower large little conical rod; Crossbeam 2 is cylindric bar; Support 1 is provided with pin joint apart from 2/3-3/4 place, ground, and crossbeam 2 end is also provided with pin joint.The pin joint of the pin joint on support 1 and crossbeam 2 is hinged.Meanwhile, in the middle part of support 1 top and crossbeam 2, be provided with stay thimble, between strained by bracing wire 3.Indicator lamp can be installed at the free end of crossbeam 2.
