Abstract
The utility model provides a pin preventing falling from high altitude, and the pin comprises a pin body (1) which is arranged on an iron tower angle steel (5), a tight nut (2) and a supporting nut for connecting the pin body and a pole and tower angle steel. The pin is characterized in that the outer end of the pin body is additionally provided with an anti-sliding heave (4), the supporting nut is changed into a drop-preventing nut (3), the inner hole structure part of which has no screw thread, beside the function for fixing the pin, the drop-preventing nut also can prevent the pin from being impacted to cause the pin to rupture. As a firm component on the pole and tower, the pin preventing falling from high altitude of the utility model can meet the requirement of the working regulation of the electrical power safety, can effectively prevent a safety belt tag from surging from the pin, prevent the operator from falling from high altitude, and have the advantages of strong applicability, low cost, easy popularization and use.
Description
One, technical field
The utility model relates to a kind of pin nail of falling in the high-altitude of being used to prevent, is applicable to the shaft tower of industry pin nail climb types such as electric power, communication.
Two, background technology
Climbing shaft tower is that industries such as electric power, communication are carried out the most basic in a service work operation; and in the climbing iron tower of industry operating maintenance work high above the ground such as present domestic electric power, communication, the staff does not have suitable easy, quick, economic fall arrest safeguard measure as yet.Usually industry work high above the ground personnel such as electric power, communication are when shaft tower up and down, general using pin spike devices, and present employed yi word pattern pin nail, security reliability is poor, only possesses supporting role, does not possess the anti-falling protection effect.
Three, summary of the invention
The purpose of this utility model provides a kind of deficiency that can overcome common pin nail, can guarantee that ascend operation personnel safety belt in shaft tower process up and down buckles not the pin nail of slippage voluntarily.
The pin nail falls in anti-high-altitude of the present utility model, comprise the pin nail body that is contained on the steel tower corner iron, clamp nut, back nut that pin nail body is connected with the shaft tower angle steel, it is characterized in that having additional anti-slip projection in the outer end of pin nail body, this anti-slip projection is used to prevent that safety belt from buckling buckles into not side direction slippage behind the pin nail body; Described back nut changes anti-fall nut into, and the inner hole structure of anti-fall nut does not partly have screw thread, and this anti-fall nut can prevent again that except having the effect of fixing feet nail the pin nail is subjected to strong impact force and causes the phenomenon of pin nail fracture to take place.
Described anti-slip projection is annular, square, circular or other shapes, and the height of single anti-slip projection is 1mm-20mm, and width is 1mm-30mm.
Described anti-fall nut thickness is 13mm-30mm, and the width that the inner hole structure of anti-fall nut does not have a thread segment accounts for the 1/4-2/3 of anti-fall nut thickness, and the anti-fall nut in back is installed, and not have the gap that thread segment and pin follow closely body and do not have between the thread segment be 0.1mm-5mm.
When the staff climbs shaft tower, alternately be buckled in the new anti-high-altitude of this practicality pin that falls with buckling of two safety belts (rope) and nail on and to climb shaft tower safely.
Fall pin nail of anti-high-altitude of the present utility model, the firm member as on the shaft tower can satisfy the requirement of electric power safety working regulation, can prevent effectively that safety belt from buckling from pin nails on slippage, prevents that the operating personnel from falling from the high-altitude, and it is strong to have applicability, cost is low, the advantage that is easy to promote the use of.
Four, description of drawings
Accompanying drawing 1 is the fall overall schematic of pin nail of anti-high-altitude of the present utility model;
Accompanying drawing 2 is fall anti-fall nut cutaway views of pin nail of anti-high-altitude of the present utility model;
Accompanying drawing 3 is fall side views of pin nail of anti-high-altitude of the present utility model;
Accompanying drawing 4 is fall user mode schematic diagrames of pin nail of anti-high-altitude of the present utility model;
Among the figure 1 is pin nail body, the 2nd, and clamp nut, the 3rd, anti-fall nut, the 4th, anti-slip projection, the 5th, the shaft tower angle steel, the 6th, safety belt buckles, and the 7th, safety belt, the 8th, the no thread segment of anti-fall nut.
Five, the specific embodiment
Be that example further specifies the specific embodiment of the present utility model with the anti-high-altitude of the M16 pin nail that falls below, shown in accompanying drawing, the anti-high-altitude of the present utility model pin nail pin nail that falls comprises pin nail body 1, clamp nut 2, anti-fall nut 3.Inner end at pin nail body (1) has screw thread, and there is crotch the outer end; Have at the crotch place 2 anti-slip protruding 4, anti-slip protruding 4 height are 8mm, longly are 16mm, wide is 6mm.Pin nail body 1 the inner is fixed on the steel tower corner iron 5 by clamp nut 2 and anti-fall nut 3, wherein anti-fall nut 3 thickness are 16mm, inner hole structure does not partly have screw thread, the width of its no thread segment 8 accounts for 1/3 of anti-fall nut thickness, and the gap of installing between anti-fall nut 3 no thread segments 8 in back and the pin nail body 1 no thread segment is 1mm.
Claims (3)
1, pin nail falls in a kind of anti-high-altitude, comprise the pin nail body (1) that is contained on the shaft tower angle steel (5), clamp nut (2), back nut that pin nail body (1) is connected with the shaft tower angle steel is characterized in that having additional anti-slip projection (4) in the outer end of pin nail body (1); Back nut changes anti-fall nut (3) into, and the inner hole structure of anti-fall nut (3) does not partly have screw thread.
2, fall pin nail of anti-high-altitude according to claim 1 is characterized in that described anti-slip projection (4) is annular, square, circular or other shapes, and the height of single anti-slip projection (4) is 1mm-20mm, and width is 1mm-30mm.
3, pin nail falls in anti-high-altitude according to claim 1, it is characterized in that described anti-fall nut (3) thickness is 13mm-30mm, the width that the endoporus of anti-fall nut (3) does not have a thread segment (8) accounts for the 1/4-2/3 of anti-fall nut (3) thickness, and it is 0.1mm-5mm that the gap that back no thread segment of anti-fall nut (3) and pin follow closely between the no thread segment of body (1) is installed.
