Abstract
The present invention relates to a rubber shake reductor of vibration and impulsion, which is a shake reducing device installed between a vibration and impulsion device and a hanging tube and is involved with the method of vibration and impulsion as well as water flushing to reinforce soft grounds quickly. The present invention aims at improving the prior art and manufacturing a rubber shake reductor which can replace a metal universal joint. The present invention is technically characterized in that the rubber shake reductor is composed of a metal ring flange, a screw bolt, an inner ring, a nylon cord thread layer and a rubber body. Compared with the prior art, when used, the present invention has the advantages of tensile resistance, torsion resistant, shock resistance and long service life. The work efficiency of the rubber shake reductor is ten times as high as the metal universal joint, and the cost of the rubber shake reductor is sixty percent of that of the metal universal joint. In addition, the present invention also has the advantages of no noise, reduction of the original production process and convenient assembly and disassembly.
Description
Rubber absorbers of the present invention, when belonging to the vibrofloation fastly fastening flexible ground, a damping device between vibrating impacter and the swing pipe.
Before the present invention, existing technology is: a kind of vibration node is set between vibrating impacter and swing pipe, produces certain relative displacement according to this vibrations node in the work, prevent that joint bolt is sheared.Be head it off, common way is to adopt mechanical metal universal joint, as damping device.Because universal joint is made of metal material processing, thus in use, not only tension, antitorque, anti seismic efficiency is poor, but also because of bearing the impact of vibrations load all the time, wearing and tearing are big, working life weak point.Simultaneously in the construction, elastic cable paper and water-filled pipe from the universal joint edge by the time very easily be damaged and produce the electric leakage water leakage phenomenon.So both dangerous, influence Plant in good condition and work efficiency progress again.Besides noise is big in construction, and 90 degree water pipe elbows are stopped up by silt particle easily, change dismounting and need expend the long period, and maintenance has certain difficulty, and is very inconvenient.
Through preliminary search, and do not find same technical characteristics is arranged, so the present invention is different from prior art with the present invention.
Purpose of the present invention will be improved prior art exactly, makes a kind of desirablely, can replace the rubber absorbers of mechanical type metal universal joint.It not only can be in vibrofloation apace tension during strengthening soft foundation, antitorque, buffering and damping effect good, improves throughput, simplifies working procedure, and can also greatly reduce the cost of vibration damper.
The present invention is a kind of flexible rubber vibration damper, and its major technology feature is: it is by flange plate, bolt, interior ring, cord floor, rubber body, form the black rubber goods that hollow cylinder type two ends have flange plate.
Specific practice is: flange plate, interior ring are to be processed into thick sheet metal, and the sandblast scale removal is fastening with bolt assembling, and with cord floor, rubber body moulding, sulfuration forms.Cord floor is to make by the calendering rubberizing with nylon thread.Rubber body contains natural gum and synthetic rubber and other rubber chemicals.
The present invention is a kind of novel rubber shake-reductor of vibration and impulsion.It has good tension, antitorque, buffering and damping effect compared with the prior art.Vibration damper of the present invention, owing to be fastening with the nylon cord and the steel loop of rubber and high strength, and adopt high-intensity steel viscose binder to connect with the metal flange dish, and so in use damping effect is good, noise free, fatigue performance is good.It has also avoided elastic cable paper, water pipe in vibration damper by time wearing and tearing electric leakage, leak and silt particle blocking phenomenon that 90 degree water pipe elbows cause, simultaneously safe and reliable, more former operation is simplified, and changes easy accessibility.Not still ten of the metal universal joint times of working life and working efficiencies, and can save Master Cost, cost is low then to be 60 percent of metal universal joint.
Accompanying drawing is the sectional drawing according to the rubber shake-reductor of vibration and impulsion of the present invention's proposition.
Describe the details and the working condition of the rubber shake-reductor of vibration and impulsion that proposes according to the present invention in detail below in conjunction with accompanying drawing.
The details of this vibration damper comprises following:
Among the figure 1, flange plate; 2, bolt; 3, interior ring; 4, cord floor; 5, rubber body.
The working condition of this vibration damper is: in use, should be screwed vibration damper between vibrating impacter and swing pipe, make vibration damper stressed evenly.When level lifting vibrating impacter, use guard bar vibration damper is protected, be strictly on guard against and tear damage open.When vertically driving piles, the elasticity superior according to rubber can play bumper and absorbing shock, noise elimination well, the effect of protection vibrating impacter.
Most preferred embodiment of the present invention is further instruction in addition in conjunction with the accompanying drawings.
Specific embodiment is as follows:
Bolt 2 among the figure, M18 to M20 millimeter.
Ring 3 among the figure, thick 10 to 16 millimeters, 215 millimeters of outer diameters, 175 millimeters of inner diameters.
Above-mentioned flange plate 1, interior ring 2 all adopt 10 to 30 millimeters steel plates to be processed into, and the sandblast scale removal is fastening with bolt 2 assembling, and coated one deck P-7 and two layers of 511T high-strength structureal adhesives and one deck contain 1 16 rubber cement.
Cord floor 4 among the figure, adopt nylon thread, after the calendering rubberizing, are cut into widely 180 to 260 millimeters, long 520 to 900 millimeters, are divided into longitude and latitude and tear open for two layers and be affixed on the inner glue layer, and clad on the interior ring 3 of a bed thickness 10 mm film, as the framework layer of goods.
Rubber body 5 among the figure, and is high 190 to 320 millimeters, 250 to 320 millimeters of outer diameters, and 130 millimeters of inner diameters are divided into inner glue layer, mesoglea, outer glue-line.Used raw material possess good endurance and dynamic aging performance, and the coefficient of waste is little, natural rubber that elasticity is high and butadiene rubber and usefulness, and dose other rubber chemicals.Manufacture technology is on 18 to 22 cun rubber mixing machines, plasticates earlier, then carry out mixing, during use on 18 cun rubber mixing machines the heat refining slice.The condition of its heat refining is: the rubber mixing machine capacity is about 45 kilograms, and the roller temperature is preliminary roller 65 degree, and back roller is 55 degree, knit time 6 to 10 minutes, and film is prolonged in voltage supply behind the heat refining, uses after 4 hours standing times.
Moulding then, sulfuration.The condition of sulfuration is: vapor tension is 4 kilograms for every square centimeter, and the time is 120 minutes.
Rubber absorbers of the present invention, tensile strength are 10 to 15 tons, are applicable to the bumper and absorbing shock between 13 to 55 kilowatts of vibrating impacters and the swing pipe.
