Description
Technical field
The utility model relates to safety tongs, specifically a kind of floating type installing mechanism of safety tongs.
Background technology
Safety tongs is widely used in various jacking system (such as man lift, Cargo Lift, piler, elevator etc.), and its effect carries out safety arrestment to jacking system, prevents jacking system generation falling accident thus.Existing safety tongs limit due to self structure, there are the following problems in actual applications: because the guide rail of jacking system exists straightness error, also error is there will be in actual installation process, the straightness accuracy installing rear rail is caused to be difficult to meet the actual requirement of safety tongs, the gap between the jaw of safety tongs and guide rail is caused to change at the crooked position of guide rail and to exceed design gaps scope thus, thus cause safety tongs cannot timely and effectively to be braked at the crooked position of guide rail, and then cause jacking system generation falling accident.Based on this, be necessary invention a kind of brand-new safety tongs floating type installing mechanism, cannot the problem of timely and effective braking at the crooked position of guide rail to solve existing safety tongs.
Summary of the invention
The utility model cannot the problem of timely and effective braking at the crooked position of guide rail in order to solve existing safety tongs, provides a kind of floating type installing mechanism of safety tongs.
The utility model adopts following technical scheme to realize: a kind of floating type installing mechanism of safety tongs, comprises guide rail, elevator car, safety tongs; Elevator car is slidably mounted on guide rail; Also comprise support guide block, positioning guide pulleys, spring perch, pre-compressed spring; The clamp block of safety tongs runs through movably and is installed on the first side wall of elevator car; Along respectively offering two guiding gap on the right of the inside portion left margin of the clamp block of safety tongs and inside portion; The number of support guide block is four; Four support guide blocks all vertically run through and are fixed on the first side wall of elevator car, and four support guide block one_to_one corresponding are arranged in four guiding gap; The number of positioning guide pulleys is two; On the upper edge, inside portion that the wheel shaft of first positioning guide pulleys runs through the clamp block being fixed on safety tongs simultaneously and upper edge, outside portion; On the lower edge, inside portion that the wheel shaft of second positioning guide pulleys runs through the clamp block being fixed on safety tongs simultaneously and lower edge, outside portion; The wheel face of two positioning guide pulleys all presses on guide rail; Spring perch is fixed on the front, inside portion of the clamp block of safety tongs; The number of pre-compressed spring is two; The axis of two pre-compressed springs is all vertical with guide rail, and the axis of two pre-compressed springs is all parallel with the front, inside portion of the clamp block of safety tongs; The tail end of two pre-compressed springs is all fixed with spring perch; The head end of two pre-compressed springs is all fixed with the inside face of the second sidewall of elevator car, and the second sidewall of elevator car is mutually vertical with the first side wall.
Specific works process is as follows: when elevator car is elevated along guide rail, and under the precompressed compression effect of two pre-compressed springs, the wheel face that the clamp block of safety tongs promotes positioning guide pulleys presses on guide rail.If some position of guide rail bends, then when positioning guide pulleys moves to the crooked position of guide rail, under the precompressed compression effect of two pre-compressed springs, the clamp block of safety tongs can be slided along left and right directions (perpendicular to lifting direction) under the common constraint of support guide block with guiding gap, all the time the wheel face promoting positioning guide pulleys thus presses on guide rail, thus makes the gap between the jaw of safety tongs and guide rail remain unchanged at the crooked position of guide rail and fall into all the time within the scope of design gaps.Based on said process, compared with existing safety tongs, the floating type installing mechanism of a kind of safety tongs described in the utility model is by adopting floating structure, the gap between the jaw of safety tongs and guide rail is made to remain unchanged at the crooked position of guide rail and fall into all the time within the scope of design gaps, make safety tongs can timely and effectively brake at the crooked position of guide rail thus, thus thoroughly prevent jacking system generation falling accident.
The utility model is rational in infrastructure, it is ingenious to design, and efficiently solving existing safety tongs cannot the problem of timely and effective braking at the crooked position of guide rail, is applicable to various jacking system (such as man lift, Cargo Lift, piler, elevator etc.).
