Utility model content
For falling proof device Problems existing in above-mentioned prior art, the utility model provide a kind of dismounting fast, moment self-locking, the anti-falling overhead self-locking device of operating personnel's personal safety can be guaranteed.
The technical scheme that problem to be solved in the utility model is taked is: anti-falling overhead self-locking device, comprise protective rope wire clamp, brake self-locking block, connecting axle, protective rope accepting groove is provided with in described protective rope wire clamp, described brake self-locking block one end is provided with safety belt connecting hole, brake self-locking block other end outer wall is arranged at intervals with detent bumps, self-locking grooves is formed between described detent bumps, brake self-locking block is provided with pin shaft hole, the axle sleeve that described connecting axle comprises limited block and is connected with limited block, it is matched in clearance between axle sleeve and pin shaft hole, axle sleeve lower end is provided with symmetrical hole clipping, briquetting is provided with in described axle sleeve, described briquetting outside is wound with coil tension spring, one end of coil tension spring connects the top of briquetting, the other end of coil tension spring is connected with shell fragment, described shell fragment two ends are symmetrical arranged limited location hoodle, described spacing hoodle can snap in hole clipping.
Further, torsion spring is connected with between brake self-locking block and protective rope wire clamp.
The utility model advantage is compared to existing technology: 1, each parts quick release of the utility model, and protective rope through fast, and there will not be bolt to get rusty to be difficult to open the situation of wire clamp; 2, detent bumps brake self-locking projection arranged and self-locking grooves surface area frictional force that is large, that produce is large, decreases the height of self-locking time and operating personnel's tenesmus, prevents from producing unnecessary personal injury to operating personnel; 3, the utility model can any point move and remove on protective rope, can adjust fixed position at any time when operation, makes operating personnel can in larger scope of operation work.

Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with detailed description of the invention, the utility model is described in further detail with reference to the accompanying drawings below.
As Fig. 1, 2, 3, shown in 4 and 5, described anti-falling overhead self-locking device, comprise protective rope wire clamp 2, brake self-locking block 4, connecting axle 3, protective rope accepting groove 9 is provided with in described protective rope wire clamp, protective rope accepting groove cross section is in " U " shape, described brake self-locking block one end is provided with safety belt connecting hole 5, staff's safety belt is with it worn on for connecting, brake self-locking block other end outer wall is arranged at intervals with the detent bumps 7 having seen arcuation distribute, detent bumps cross section is circular arc, be formed between described detent bumps on self-locking grooves 8(self-locking grooves and detent bumps and should have rough grain, for strengthening frictional force), brake self-locking block is provided with pin shaft hole 6, described connecting axle comprises limited block 10 and axle sleeve 13, described axle sleeve (step on axle sleeve) and pin shaft hole matched in clearance, described axle sleeve lower end is provided with the hole clipping (not marking in figure) of two symmetries, briquetting 11 is provided with in described axle sleeve, described briquetting outside is wound with coil tension spring 14, one end of coil tension spring connects the top of briquetting, the other end of coil tension spring is connected with shell fragment 15, described shell fragment two ends are symmetrical arranged limited location hoodle 12, spacing hoodle can snap in hole clipping (not marking in figure).
In order to accelerate the degree of tightness conversion speed of reaction time and brake self-locking block, between brake self-locking block and protective rope wire clamp, be connected with torsion spring 16.
In use, first press the briquetting on connecting axle, coil tension spring is driven to exert oneself downwards, be arranged on the spacing hoodle at shell fragment two ends, shrink in cavity, then upwards limited block is mentioned, connecting axle and brake self-locking block just can be separated with protective rope wire clamp, then the protective rope of hanging in height is passed protective rope accepting groove, then the pin shaft hole of brake self-locking block is aimed at the pin shaft hole on protective rope wire clamp, pressing connecting axle also passes pin shaft hole, unclamp briquetting, spacing card bead is stuck in the hole clipping on axle sleeve, at this moment, be half tensioning state between brake self-locking block and protection rope clamp rope, when the unexpected landing of operating personnel, brake self-locking block was pulled downwards by moment, at this moment the detent bumps on brake self-locking block and self-locking grooves are at once by the high frictional force clamping protective rope on surface area, thus prevent the falling from high altitude of operating personnel.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to detailed description of the invention etc.; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement; and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the scope of claim of the present utility model protection.
