Abstract
The invention discloses a safety belt rod top hanging hat. A hanging ring is installed on a casing pipe through a bolt. A bolt limiting groove is formed in the casing pipe. The hanging ring is provided with a threaded hole and a connecting lug. Compared with the prior art, the safety belt rod top hanging hat provides a fixing point of a safety belt for overhead working personnel, the safety belt will not drop or slide, and safety of the overhead working personnel is guaranteed.
Description
Technical field
The present invention relates to a kind of safety guard.
Background technology
10KV and following distribution lead often adopt cement electric pole to support, and also often adopt cement electric pole to support optical cable or cable in communication network.And in the masthead course of work, safety belt can't firmly articulate, the staff's that can not adequately protect safety.The work high above the ground personnel safety belt very easily occurs and deviate from if safety belt is hung over the electric pole top, and the high-altitude falling accident takes place; If the safety belt utmost point is hung over below the cross-arm of electric pole, then safety belt easily glides and loses protection staff's effect.
Summary of the invention
Given this, the object of the present invention is to provide a kind of safety guard that can firmly articulate safety belt.
For solving above technical problem, technical scheme provided by the invention is, provides a kind of safety belt masthead to hang cap, and link is installed on the sleeve pipe by bolt, and sleeve pipe is provided with a bolt stopper slot, and link is provided with screw and engaging lug.
Preferably, the internal diameter of described sleeve pipe increases from top to bottom gradually.
Preferably, described sleeve pipe is steel pipe or aluminium-alloy pipe.
Further, described bolt stopper slot is arranged on bushing outer surface.
Preferably, described bolt stopper slot is around one week of bushing outer surface.
Preferably, described engaging lug is a pair of, is that the line of symmetry symmetry arranges with the link axial line.
Compared with prior art, a technical scheme in the technique scheme has following advantage:
1, the present invention has adopted sleeve pipe, can directly be set on the electric pole.The internal diameter of sleeve pipe can be preset when producing, and the diameter of general cement electric pole increases from top to bottom gradually, and sleeve pipe is fixed after electric pole is slipped to a certain position on the electric pole cross-arm, can be again toward falling.The fixing point of a connection safety belt is provided can for behind sheathed the finishing the aloft work personnel, safety belt can not come off or landing, has guaranteed work high above the ground personnel's safety.
2, the internal diameter of sleeve pipe increases from top to bottom gradually, the external diameter of its internal diameter varies and electric pole changes always, so that strength and the applying of electric pole external diameter in the sleeve pipe, the contact area of sleeve pipe and electric pole is big, sleeve pipe is difficult for rotating in use, guarantees that the work high above the ground personnel can control balance.
3, the present invention adopts the bolt stopper slot, and under the effect of bolt, link moves on the vertical direction again, can only rotate around axial line.During installation, according to work high above the ground personnel's construction direction, rotate link to suitable location, tight a bolt then, link is completely fixed, guarantee that the work high above the ground personnel can control balance.
Description of drawings
Fig. 1 is the partial sectional view of a preferred embodiment of the present invention.
Fig. 2 is link front view in a preferred embodiment of the present invention.
The specific embodiment
Describe below in conjunction with accompanying drawing and a specific embodiment.
Referring to Fig. 1 to Fig. 2.The described a kind of safety belt masthead of present embodiment is hung cap, comprises sleeve pipe 10 and a link 20 of a steel or aluminium alloy matter.Bore is less than following bore on the sleeve pipe 10, and its lateral surface is provided with a bolt stopper slot 11, and bolt stopper slot 11 is annular, around 10 1 weeks of sleeve pipe.Link 20 is provided with screw and engaging lug 21, and link 20 is installed on the sleeve pipe 10 by bolt 30, during installation, in the bolt 30 inserting bolt stopper slots 11.During use, bolt 30 tightened prevent that link 20 from rotating.Engaging lug 21 is a pair of, is that the line of symmetry symmetry arranges with the axial line of link.
Only be preferred embodiment of the present invention below, should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
