Abstract
The utility model relates to a liftable guard rail pile used for highways, which belongs to road equipment, particularly a road guard rail pile which is used for limiting traffic behaviors. The utility model is mainly composed of a sleeve pipe (6) and an extraction pipe (7) which are buried into the ground, wherein, the extraction pipe (7) is embedded into the sleeve pipe (6) and forms a sliding fit with the sleeve pipe (6); the center of the extraction pipe (7) is provided with a threaded rod (9), the lower end of the threaded rod (9) is provided with a nut (10) which is in the shape of a circular platform, and the threaded rod (9) is in a screw thread fit with the nut (10). The utility model has the advantages of convenient and rapid construction and easy maintenance and replacement, and the utility model can avoid large-area damage caused by chain reaction because the utility model is singly used.
Description
The utility model relates to road furniture, particularly a kind of road guard stake of stop limits traffic behavior.
In the speedway median strip is the current needs that satisfy highway maintenance, maintenance and emergency relief vehicle, and (2-3 kilometer) disconnects usually at a certain distance, replaces with removable guardrail stake.At present, normally used device has two kinds: (1) longitudinal extension formula, shortcoming are the cost height, damage and repair difficulty, and the maintenance phase is long: (2) card edge type, shortcoming are to play the effect of good isolation vehicle.
The utility model purpose is according to above-mentioned the deficiencies in the prior art part, proposes a kind of novel lifting highway guardrail stake, and this technical products is simple in structure, and cost is low, and is widely applicable.
The utility model purpose realizes having following technical scheme to realize:
The utility model is mainly by buried sleeve pipe (6) with extract pipe (7) and constitute, extract pipe (7) and embed sleeve pipe (6), be slidingly matched with sleeve pipe (6), be provided with screw rod (9) extracting pipe (7) central authorities, the low side of screw rod (9) is provided with round table-like nut (10), screw rod (9) and nut (10) threaded engagement, be provided with piston ring (8) extracting between pipe (7) low side and the round table-like nut (10), the end of screw rod (9) has been provided with the bearing (2) of support effect, be provided with spherical crown shape end cap (3) extracting pipe (7) top, central authorities at spherical crown shape end cap (3) are provided with tegillum (1), and tegillum (1) cooperates with spherical crown shape end cap (3) hinge.
The utility model has the advantages that this technical products is simple in structure, cost is low, and is widely applicable, quick construction, convenience, and easy-maintaining is changed, and can avoid chain reaction because of independent use and cause large tracts of land to be damaged.
Accompanying drawing 1 is the utility model raised position structural representation;
Accompanying drawing 2 is the utility model landing place structural representation;
The utility model feature and other feature are described in further detail by embodiment below in conjunction with accompanying drawing:
As accompanying drawing 1,2 show, the utility model is mainly by buried sleeve pipe (6) with extract pipe (7) and constitute, extract pipe (7) and embed sleeve pipe (6), be slidingly matched with sleeve pipe (6), be provided with screw rod (9) extracting pipe (7) central authorities, the low side of screw rod (9) is provided with round table-like nut (10), screw rod (9) and nut (10) threaded engagement, be provided with piston ring (8) extracting between pipe (7) low side and the round table-like nut (10), the end of screw rod (9) has been provided with the bearing (2) of support effect, the upper and lower settings of bearing (2) has extracting pipe (7) top and is provided with spherical crown shape end cap (3), central authorities at spherical crown shape end cap (3) are provided with tegillum (1), and tegillum (1) cooperates with spherical crown shape end cap (3) hinge.At screw rod (9) the top section of extracting the setting of pipe (7) central authorities is square, buried sleeve pipe (6) length is 500-1200mm, be provided with tegillum (1) size and screw rod (9) size is complementary in the central authorities of spherical crown shape end cap (3), purpose is can stretch into rotary screw (9) in tegillum (1) with extraordinary instrument, and this is that those skilled in the art institute is understood easily.
When the utility model is installed, can earlier the hollow section suitable with size of outer tube be driven underground, extract hollow section afterwards, again the utility model be put into.When the utility model uses, will extract pipe (7) with hand earlier and extract, and use extraordinary instrument can stretch into rotary screw (9) in the tegillum (1) afterwards and make and extract pipe (7) interior low side and round table-like nut (10) and move up, make piston ring (8) tensioner.After using, use extraordinary instrument can stretch into rotary screw (9) in the tegillum (1) again and make and extract pipe (7) low side and round table-like nut (10) moves down, make piston ring (8) lax, extract pipe (7) return.The utility model spacing generally is controlled at about 1800mm, and quantity is set can be determined as the case may be.
Obviously, the utility model also is applicable to residential quarters, forbids or limit the place of vehicle pass-through during the walkway.
