Abstract
The utility model relates to a novel crane buffer, which comprises an installing bottom plate. The installing bottom plate is provided with bolt installing holes. The utility model has the technical scheme that the installing bottom plate is fixedly connected with an outer sleeve; a slide sleeve is clamped at the opening end of the outer sleeve through an annular fixing sheet; the front end of the slide sleeve is provided with a front head plate; the back end of the slide sleeve is provided with a back head plate; the annular fixing plate is clamped on the outside of the slide sleeve between the front head plate and the back head plate; and a polyurethane buffer body is arranged in a cavity formed by the back head plate, the outer sleeve and the installing bottom plate. The utility model uses the polyurethane buffer body for replacing the traditional hydraulic damping oil, effectively solves the problem of oil leakage, and seals the polyurethane buffer body through reasonable structural design to avoid the defect of aging caused by being exposed at a high operating ambient temperature. The utility model has the advantages of high shock resistance, stable buffering, corrosion and aging resistance, long service life, safety, reliability and the like.
Description
Technical field
The utility model relates to crane safety device technique field, specifically a kind of novel hoisting crane energy disperser.
Background technology
The hoisting crane energy disperser is as an important safety device on the hoisting crane, and can technical parameters such as the protection effect of energy disperser itself, service life have directly influenced hoisting crane safe operation.Energy disperser commonly used at present has various mechanism such as spring loaded, rubber type, fluid pressure type, polyurethane formula, damping type, liquid-gas type, cuts both ways.Here only introduce polyurethane formula energy disperser and hydraulic draft gear, polyurethane formula buffer structure mostly is and is fixed with the polyurethane buffering piece on metallic interconnect, and the protection top board is housed at the bump rubber top, the energy disperser of this structure is under normal working environment, not only has protection effect preferably, also have advantages such as volume is light, resiliency good, long service life simultaneously, but it is higher to work as operating ambient temperature, exposed polyurethane buffering piece is easy to wear out, to its serviceability with all produce adverse influence shelf life; Though and the hydraulic draft gear temperature influence is less, often because leakage of oil produces adverse influence to its serviceability.
Summary of the invention
It is the novel hoisting crane energy disperser of basic complex optimum with polyurethane formula energy disperser and hydraulic draft gear that the purpose of this utility model provides a kind of.
The purpose of this utility model is achieved in that it comprises the installation base plate of strap bolt mounting hole, it is characterized in that: base plate is installed is captiveed joint with overcoat, be installed with a slip cap at the overcoat open end by annular fixed plate, the rear end that the front end of this slip cap is provided with front top plate, this slip cap is provided with the back top board, the annular fixed plate is installed on the slip cap outside between front top plate and the back top board, is provided with the polyurethane buffering body in the cavity that back top board, overcoat and installation base plate form.
The utility model replaces traditional hydraulic damping oil with polyurethane body, and actv. has solved the leakage of oil problem; And by reasonable structural design polyurethane body is sealed, avoided the disadvantage that in higher operating ambient temperature, wears out owing to exposing.So solve the utility model of above-mentioned two problems and possessed that anti-impact force is strong, stable buffering, withstanding corrosion are aging, long service life, advantage such as safe and reliable.
Description of drawings
Fig. 1 is a semi-sictional view structural representation sketch of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
Shown in Fig. 1-2, keystone configuration of the present utility model comprises the square installation base plate 1 of four strap bolt mounting holes 8, square installation base plate 1 is by being bolted on the crane beam, square installation base plate 1 is also captiveed joint with cylindrical jacket 3, by annular arrangement fixed plate card 5 a cylindrical slip cap 6 is housed at the overcoat open end, the front end of this cylindrical slip cap is provided with circular front top plate 7, the rear end of this cylindrical slip cap is provided with circular back top board 4, annular arrangement fixed plate card 5 is contained in cylindrical slip cap 6 outsides between circular front top plate 7 and the circular back top board 4, and top board 4 after circle, be provided with polyurethane buffering body 2 in the cavity that cylindrical jacket 3 and square installation base plate 1 form.
Circular front top plate 7 is the impact face during work, be subjected to sliding in cylindrical slip cap 6 cavity that top board 4, cylindrical jacket 3 and square installation base plate 1 form after circle behind the impulsive force, polyurethane buffering body 2 produces the deformation antagonistic forces and the effect that realizes cushioning.
Above-mentioned square installation base plate 1 can be replaced with the circular mounting base plate, and cylindrical jacket 3 and cylindrical slip cap 6 can be replaced with prismatic overcoat and prismatic slip cap.
