Abstract
The invention relates to a buffer which comprises a mounting bottom plate with a bolt mounting hole. The buffer is characterized in that at least three wrapped connecting skeletons are punched on the mounting bottom plate; the mounting bottom plate is connected with a polyurethane buffering column body through the connecting skeletons; and the connecting skeletons are inserted in the polyurethane buffering column body. The connecting skeletons are arranged by the punching method, therefore the rigid connection index between the mounting bottom plate and the connecting main body is decreased, and the protection function is effectively performed; as the connecting skeletons are not welded on the mounting bottom plate, the pollution to the environment is decreased in the manufacturing process. The connecting skeleton has the advantages of simple structure, material saving and decrease of manufacturing cost. The invention also has the advantages of strong anti-shock capability, stable buffering, corrosion and aging resistance, long service life, safety and reliability, and the like.
Description
Technical field
The present invention relates to the mechanical safety device technical field, specifically a kind of buffer.
Background technique
As everyone knows; buffer is the important safety protective equipment of machineries such as hoist, elevator; purpose is the protection by buffer; reduce even avoid the damage of mechanical connection main body, thus technical parameters such as the protection effect of buffer itself, working life directly influenced connected machinery can safe operation.Buffer commonly used at present has various mechanism such as spring, rubber type, hydraulic type, polyurethane formula, damped type, liquid-gas type, cuts both ways.Here only introduce polyurethane formula buffer, polyurethane formula buffer structure mostly is and is fixed with the polyurethane buffering piece on metallic interconnect, its means of fixation is that sleeve structure is set on metallic interconnect mostly, filled polyurethane in sleeve structure, such means of fixation manufacture cost is higher, and sleeve structure is as fixing by welding, and its rigidity index is higher, when accepting to impact, easily to mechanical body.
Summary of the invention
The purpose of this invention is to provide a kind of polyurethane formula buffer.
The object of the present invention is achieved like this: it comprises the installation base plate of strap bolt mounting hole, it is characterized in that: punching press is provided with the connection skeleton of at least three warpages on the installation base plate, base plate is installed is connected with the polyurethane buffering cylinder, connect skeleton and be inserted in the polyurethane buffering cylinder by connecting skeleton.
Described installation base plate is square or the circular mounting base plate.
For the density that increases the polyurethane buffering cylinder improves its cushioning effect, the polyurethane molecular amount of described polyurethane buffering cylinder is 300～6000.
In order to increase frictional force, the top of described polyurethane buffering cylinder is provided with anti-skidding projection.
Connection skeleton of the present invention adopts the impact style setting; make and base plate is installed and is connected the index reduction that is rigidly connected between the main body; more effective playing a protective role; simultaneously owing to be not welded on the installation base plate; therefore reduced pollution in the manufacture process to environment; simple from structure connection skeletal structure of the present invention itself, save material, reduced manufacture cost.The present invention has possessed also that anti-impact force is strong, stable buffering, corrosion-resistant aging, long service life, advantage such as safe and reliable.
Description of drawings
Fig. 1 is a broken section structural representation sketch of the present invention;
Fig. 2 is the worm's eye view of Fig. 1.
The present invention is described in further detail by example below in conjunction with accompanying drawing, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
Embodiment
Shown in Fig. 1-2, main structure of the present invention comprises the square installation base plate 4 of four strap bolt mounting holes 5, square installation base plate 4 is by being bolted on crane beam or the elevator base, punching press is provided with the connection skeleton 3 of four warpages on square installation base plate 4, square installation base plate 4 is connected with polyurethane buffering cylinder 1 by connecting skeleton 3, connects skeleton 3 and is inserted in the polyurethane buffering cylinder 1.For the density that increases the polyurethane buffering cylinder improves its cushioning effect, the polyurethane molecular amount of polyurethane buffering cylinder is 300～6000.In order to increase frictional force, be provided with anti-skidding protruding 2 at the top of polyurethane buffering cylinder.
The top of polyurethane buffering cylinder 1 is the impact face during work, be subjected to that polyurethane buffering cylinder 1 after the impact force produces the deformation reaction force and the effect that realizes cushioning, the polyurethane of polyurethane buffering cylinder can be extruded from the punching hole of square installation base plate 4 when impact force is excessive.
Above-mentioned square installation base plate 1 can be replaced with the circular mounting base plate.
In sum, realized purpose of the present invention.
