Summary of the invention
The purpose of this invention is to provide that a kind of backguy is easy for installation, the novel guy fastening devices of backguy secure.
The objective of the invention is to realize like this: a kind of novel guy fastening devices, anchor pin one end is a sharp cone distal, and ring is arranged on the other end; The ring of many anchor pins is enclosed within on the rib of retainer ring along same circumference versatilely, and retainer ring is welded on the inwall of position-limiting cover of taper type; The tip of stand-off passes from the position-limiting cover inner chamber, and stand-off connects firmly with position-limiting cover through steady pin mutually; The power transmission pipe front portion is inserted in and is screwed on the stand-off from the stand-off other end, and tapered tensioner ring is enclosed within on the stand-off, and tensioner ring is positioned at the front end of power transmission pipe.
The integrated parts of above-mentioned tensioner ring and power transmission pipe.
Above-mentioned anchor pin is four, the six roots of sensation or eight.
Also have the installation auxiliary tool: an end perforate, the other end are the cylinder of end socket.
Compared with prior art, beneficial effect of the present invention is:
1, novel structure, simple, practical.
2, low cost of manufacture is convenient to popularize.
3, the ground easy construction is buried in backguy, after the installation, and the anchoring secure.
Advantage of the present invention will combine the specific embodiment further to set forth.
The specific embodiment
Shown in Figure 1, the novel guy fastening devices, anchor pin 5 one ends are sharp cone distal, and ring is arranged on the other end; The ring of many anchor pins 5 is enclosed within on the rib 4a of retainer ring 4 along same circumference versatilely, and retainer ring 4 is welded on the inwall of position-limiting cover 3 of taper type; The tip of stand-off 1 passes from the position-limiting cover inner chamber, and stand-off connects firmly with position-limiting cover through steady pin 2 mutually; Power transmission pipe 7 front portions are inserted in and are screwed on the stand-off 1 from stand-off 1 other end, and tapered tensioner ring 6 is enclosed within on the stand-off 1, and tensioner ring is positioned at the front end of power transmission pipe 7.(referring to Fig. 2 ~ Figure 14).Referring to Fig. 8, four rib 4a (coupling part by between two holes forms) are arranged, 4 anchor pins of corresponding connection on the retainer ring 4.Among Fig. 1, stand-off is from position-limiting cover left end (above-mentioned left and right be as far as Fig. 1), passes and after steady pin was fixing, the extension of stand-off and position-limiting cover formed a sharp cone distal in shape.Referring to Fig. 3 Fig. 4, insert hole 1a and the hole 3a on the position-limiting cover of steady pin 2 from stand-off the two is fixed.Tensioner ring 6 can be unitary member with power transmission pipe 7.Anchor pin 5 is four, the six roots of sensation or eight or other.Referring to Figure 15 Figure 16, auxiliary tool end perforate in 8: is installed, the other end is the cylinder of end socket.
The blind hole diameter that auxiliary tool is installed is identical with the power transmission pipe diameter of bore, and the wall thickness that the blind hole place of auxiliary tool is installed is not less than the wall thickness of power transmission pipe.
Compared with prior art, the present invention has following characteristics:
1, simple and practical.
2, the construction that makes things convenient for backguy to fix on ground: the head of stand-off (stretching out the position-limiting cover part) forms a sharp cone distal with position-limiting cover, is convenient in the soil, insert.During construction, main power is imposed on stand-off, can stand-off easily be squeezed in the soil through installation auxiliary tool (need not also can).
3, backguy in the soil fixed, improved safety: after stand-off inserts the soil; Turn power transmission pipe again; Make power transmission pipe and tensioner ring descending along stand-off, the anterior tensioner ring of power transmission pipe struts (strutting mode like umbrella) with the anchor pin, grabs the ground hook thereby form ground anchor type.
This anchorage shoe can be according to the actual requirements, and application sledgehammer etc. impacts into underground, the anchor pin expanded to open get final product.
Apparatus of the present invention are applicable to existing electric line erection construction, are specially adapted to the place of preventing stopping bar (tower) to topple over.
Anchorage shoe of the present invention is by stand-off, steady pin, position-limiting cover, retainer ring, anchor pin, tensioner ring, power transmission pipe and installation auxiliary device is formed and through preservative treatment.
Stand-off is processed by metal or hard material, end pin point; Be provided with the hole that installs and fixes pin; Be provided with the screw thread that matches with power transmission pipe along other end direction; The other end falls into ring, can be inserted in the backguy U-loop.
Steady pin is become by metal material, is cylindric, can insert the hole that is provided with on stand-off and the position-limiting cover, becomes interference fit with stand-off, prevents landing in installation process.
Position-limiting cover is processed by metal material, connects through steady pin and stand-off; The inboard is provided with the retainer ring of mooring anchor pin, and position-limiting cover and retainer ring are through welded connection.
Retainer ring is processed by metal material, is weldingly fixed in the position-limiting cover, and the anchor needle guard and can be pressed certain angle swing on retainer ring.
The anchor pin is processed by metal material, is assemblied on the retainer ring, under the effect of tensioner ring, can strut as umbrella, stops stand-off to be pulled up.
Tensioner ring is processed by metal material, and a side is little, and a side is big, and big side is pasted power transmission pipe, under the effect of power transmission pipe, the anchor pin that is affixed on stand-off is strutted, and inserts in the stand-off soil on every side.
Power transmission pipe is processed by metal material, in a tubular form, in be provided with the screw thread that matches with stand-off, an end is provided with uses the corner angle that spanner applies strength
Installation auxiliary device is processed by metal material, is an end opening, and the tubbiness of other end sealing through impacting blind end, is passed to power transmission pipe with strength, and power transmission pipe is given stand-off with strength transmission again, and the novel guy device is inserted in the soil.
The method for using of anchorage shoe of the present invention (referring to Figure 17):
1, power transmission pipe is inserted in through the stand-off tip, has edges and corners to be inserted in earlier, and be threaded to the ring place that stand-off is provided with along hand of spiral;
2, backguy U-loop 9 is inserted in stand-off, little side is most advanced and sophisticated towards stand-off;
The position-limiting cover that 3, retainer ring and anchor pin will be housed is inserted in stand-off, and little side is most advanced and sophisticated towards stand-off, and the hole of establishing on position-limiting cover and the stand-off is aligned;
After the hole of 4, establishing on position-limiting cover and the stand-off aligns, steady pin is impacted in the hand-hole;
5, installation auxiliary device is inserted in stand-off backguy side, and contacts with power transmission pipe;
6, with sledgehammer etc. the novel guy fastening devices is driven underground along the stayguy direction negative side, the novel guy fastening devices is basseted part should less being advisable, and only exposing power transmission pipe, to be provided with edges and corners best, sheds installation auxiliary device;
7, install in the ring of backguy U-loop with insertion stand-offs such as wooden sticks;
8, be inserted in the power transmission pipe edges and corners with spanner, spanner cooperates with wooden stick, power transmission pipe is moved along stand-off is most advanced and sophisticated, until revolving motionless or stand-off screws out certain-length and gets final product.
