Abstract
The invention discloses a device for preventing segments from slipping. The device comprises a fastener and a strut of which the first end is tightly fixed with a sucker, wherein the second end of the strut is tightly fixed on the fastener. By the device, an effect of preventing the segments from slipping in the lifting process can be effectively achieved; and the device has the characteristics of high slipping prevention performance, simple structure and high safety performance, and can be conveniently operated.
Description
Technical field
The present invention relates to a kind of anti-drop device, refer to a kind of section of jurisdiction anti-drop device especially.
Background technology
In the subway work process, the section of jurisdiction lifting belongs to the bigger construction sequence of safety hazard, and the section of jurisdiction counterpoise is 3 to 4 tons, and the single lifting is 2 to 3 sections of jurisdiction, promptly lifts about 10 to 12 tons of gross weight.The tradition lifting device is a suspender belt, and there is the danger of slippage to a certain extent in lifting, thereby causes bigger casualty loss accident.A kind of anti-slip device in section of jurisdiction that can effectively prevent to take place in the lifting of section of jurisdiction the slipping property incident is not arranged at present as yet, ensure the safety in the hoisting process of section of jurisdiction.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, and a kind of section of jurisdiction anti-drop device is provided, realized a kind of section of jurisdiction anti-drop device that can effectively prevent to take place in the lifting of section of jurisdiction the slipping property incident; It is strong to have the anticreep performance; Simple in structure, simple operation, safe characteristics.
The technical scheme that realizes above-mentioned purpose is:
A kind of section of jurisdiction of the present invention anti-drop device comprises that a fastener and a first end are fastened with the pole of a sucker; Second end of said pole is anchored on the said fastener.
Above-mentioned fastener comprises a shell and a plurality of slide bar; The corresponding respectively formation one in the two ends of said enclosure hollow and said shell is parallel to the trough of belt mouth of said shell bottom surface; The two sides formation one of said shell or plural number are to the skewed slot of correspondence, and each is to being slidingly equipped with a said slide bar in the said skewed slot; The distance on said skewed slot first end to base is greater than the distance on said skewed slot second end to base; Second end of said pole is anchored on the middle part of said upper surface of outer cover, and tilts to the outer casing end direction near said skewed slot second end.
Form one domatic near the upper surface of the outer casing end of above-mentioned skewed slot second end.
The present invention has been owing to adopted above technical scheme, makes it have following beneficial effect to be:
The cooperation of fastener and sucker, when making the lifting section of jurisdiction, the section of jurisdiction is firmly fixed on the suspender belt, effectively prevents in the lifting of section of jurisdiction slippage to take place, and has ensured the safety in the hoisting process of section of jurisdiction.It is strong to have the anticreep performance, simple in structure, simple operation, safe characteristics.

Fig. 1 is the structural representation of section of jurisdiction of the present invention anti-drop device;
Fig. 2 is the section of jurisdiction hoisting structure sketch map of the suspender belt relaxed state of section of jurisdiction of the present invention anti-drop device;
Fig. 3 is the section of jurisdiction hoisting structure sketch map of the suspender belt lifting state of section of jurisdiction of the present invention anti-drop device.
The specific embodiment
Below in conjunction with specific embodiment the present invention is described further.
See also Fig. 1, a kind of section of jurisdiction of the present invention anti-drop device comprises that a fastener 1 and a first end are fastened with the pole 2 of a sucker 3; Second end of pole 2 is anchored on the fastener 1.Fastener 1 comprises a shell 11 and a plurality of slide bars 12; The corresponding respectively formation one in the two ends of shell 11 inner hollow and shell 11 is parallel to the trough of belt mouth 111 of shell 11 bottom surfaces; The two sides of shell 11 form the skewed slot 112 of two pairs of correspondences, and each is to being slidingly equipped with a slide bar 12 in the skewed slot 112; The distance on skewed slot first end 1121 to the base is greater than the distance on skewed slot second end 1122 to the base; Second end of pole 2 is anchored on the middle part of shell 11 upper surfaces, and tilts to shell 11 end directions near skewed slot second end 1122.Upper surface near shell 11 ends of skewed slot second end 1122 forms one domatic 113.
See also Fig. 2, use when of the present invention, when suspender belt 5 is lax; At first be arranged in suspender belt 5 between the bottom surface and slide bar 12 of shell 11 through trough of belt 111; Shell 11 arranges to the inside that along the end setting downwards and the sucker 3 of sucker 3 incline directions skewed slot first end 1121 of skewed slot 112 is positioned at the top of skewed slot second end 1122 at this moment, and slide bar 12 down folds first end 1121 directions are promoted when wearing; Make fastener 1 and suspender belt 5 be in relaxed state; This moment, fastener 1 can be transferred up and down along suspender belt 5, fastener 1 is adjusted near 4 apical side height positions, section of jurisdiction, and then slide bar 12 is promoted downwards; Slide bar 12 is pressed close to shell 11 bottom surfaces along skewed slot 112, thereby the suspender belt 5 that will be arranged between shell 11 bottom surfaces and the slide bar 12 clamps.
See also Fig. 3; Suspender belt 5 tightens up and section of jurisdiction 4 surface formation one angle less than 90 degree to 4 inboards, section of jurisdiction under the effect of pulling force after getting into the lifting state; Fastener 1 also tilts to section of jurisdiction 4 under the drive of suspender belt 5; Because domatic 113 employing has prevented the excessive pushing tow of fastener 1 lower end and section of jurisdiction 4, prevented that fastener 1 is in the skew that on suspender belt 5, produces the position under the effect of bottom jacking force; This moment, suspender belt 5 pressed down sucker 3 through pole 2; Make sucker 3 and section of jurisdiction 4 surperficial adhesives, simultaneously, pole 2 makes fastener 1 shell 11 form the trend that moves up under the effect of pressure; Make slide bar 12 down fold second end 1122 directions under suspender belt 5 function of friction move; Thereby make fastener 1 on suspender belt 5, lock, and sucker 3 compress and adsorb section of jurisdiction 4 under the effect of pole 2, the generation of section of jurisdiction 4 slippages when having prevented lifting.
More than combine accompanying drawing embodiment that the present invention is specified, those skilled in the art can make the many variations example to the present invention according to above-mentioned explanation.Thereby some details among the embodiment should not constitute qualification of the present invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
