Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figs. 1-5, detachable transmission line of electricity external force damage prevention limit for height column provided in this embodiment includes two 1 Hes of vertical bar
A piece cross bar 2, every 1 bottom of vertical bar are equipped with ground auger 3, and the vertical bar 1 and cross bar 2 are spliced by several stainless steel tubes
It forms, the stainless steel tube of two vertical bar extreme lower positions is basic stainless steel tube 11, and described basis 11 one end of stainless steel tube processes spiral shell
Line, other all stainless steel tube both ends process screw thread, are connected between adjacent two stainless steel tubes by internally threaded sleeve 4, described
Basic 11 bottom of stainless steel tube is laterally provided with connecting hole 12, and as helical structure, connecting shaft is arranged at ground auger top within the ground auger 3 weeks
31, round tube 32 is welded at the top of the connecting shaft 31, the round tube 32 is laterally provided with jack 33, basis 11 bottom of stainless steel tube
Portion is inserted into the round tube 32, and the receptacle alignment on connecting hole and round tube, then penetrates bolt locking, the vertical bar is along high
Spend direction installation there are two connector 5, the connector 5 includes former and later two semi-circular plates 51, the end of the semi-circular plate 51 to
Plate 52 is extended to form outside, has link block 53 between two ipsilateral plates 52, ipsilateral plate 52, link block 53 wear one altogether
Lock plunger 54, the end of the link block 54 are additionally provided with cord hole 55, and wirerope 6,6 end of wirerope are installed in the cord hole
It is connected with earth anchor 7.
When installation, prepare each material, including stainless steel tube, ground auger, wirerope, earth anchor, connector etc. first, due to these
Material is all discrete, therefore transport of materials is more convenient.First by after transport of materials to destination, cross bar is carried out on ground
With the assembling of vertical bar, the standard of stainless steel tube is a meter Yi Gen, needs to select several according to length.In addition to as vertical bar most bottom
The stainless steel tube (referred to as basic stainless steel tube) in portion, the equal tapping in other stainless steel tube both ends forms external screw thread, adjacent stainless steel tube
Between connected by internally threaded sleeve, be screw thread inside inner screw sheath, therefore only the stainless steel tube of two sides need to be screwed into internal screw thread
Set.And can be connected using elbow between cross bar and vertical bar, elbow has internal screw thread, and such cross bar and vertical bar connect to one
It rises.
Then pile driving position is designed, is inserted into the round tube at the top of ground auger with hand drill bottom, then passes through circle with bolt
Then jack and hand drill bottom on pipe rotate hand drill, and then drive ground auger rotation, since the ground auger whole body is helical form, because
This can be easy to squeeze into ground auger in soil, after being driven into certain depth, and adjust ground auger direction, finally by basic stainless steel
Tube bottom end is inserted into the round tube of ground auger, and basic stainless steel tube bottom end is not screw thread, and is laterally provided with connecting hole, finally by bolt
Insertion round tube jack, connecting hole are simultaneously locked, and two ground augers use same operation and installation mode, and height-limiting bar entire so just erects
Come.
Lower two connectors finally are installed in the proper height position of vertical bar, connector is by semi-circular plate, plate and connection
Block composition, link block is rotatable, and two semi-circular plates of connector embrace vertical bar, and both ends plate is locked with lock plunger, and is locked simultaneously
It is bolted and penetrates link block.Steel wire rope end is fixed to link block, specifically, the cord hole of steel wire penetrating link block, then uses fixture
Locking, the wirerope other end is fixed with earth anchor, earth anchor is squeezed into soil, and guarantees that wirerope is tightened, a total of four wirerope
With four earth anchors, after being all installed, height-limiting frame is installed.The utility model is pierced in soil using ground auger, without construction
Concrete pedestal improves installation effectiveness.In addition, being cased with reflective plastic casing, the vertical bar on the wirerope in the present embodiment
With reflective sheeting is posted on cross bar.To remind vehicle of passing by one's way to pay attention to.
As shown in fig. 6, the earth anchor 7 is angle bar in the present embodiment, angle bar bottom is fined away, and partially has circular hole 71 on angle bar,
Angle bar is at low cost, angle bar length should long enough, just can be more stable after squeezing into ground in this way.Furthermore, it is contemplated that basis is stainless
Link position between steel pipe and ground auger determines the fastness of entire height-limiting bar, if link position corrodes, height-limiting bar holds very much
Collapse.And in practice, since ground auger is embedded in soil, link position generally within Near Ground, and basic stainless steel tube with
Ground auger is to be locked by bolt, therefore bolt is also easy to corrode.In the present embodiment, in the basic stainless steel tube and ground auger
Link position is cased with rubber case 13.Rubber case is flexible, before basic stainless steel tube is docked with ground auger, rubber case set basis is stainless
On steel pipe, after the completion of being docked with ground auger, pulls open rubber case and move down rubber case, cover link position, that is, cover
Basic stainless steel tube bottom, round tube and connecting shaft, can thus play good protection.
It describes in previous embodiment and is connected between cross bar and vertical bar by elbow, alternatively, such as Fig. 7 institute
Show, can also be connected using threeway 14, the lower end of threeway is connected respectively at vertical bar with cross bar with side, and the top port of threeway is straight
It connects and screws on speed limit direction board 8 or limit for height board, prompt vehicular traffic note that in practice, speed limit direction board can be installed with side, it is another
Side is installed by limit for height board.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
