From the above, bumper assembly of the present utility model,
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bumper assembly of vibro replacement stone column machine of the present utility model.
Detailed description of the invention
As shown in Figure 1, the structural representation of the bumper assembly of the vibro replacement stone column machine provided for the utility model, this bumper assembly is for the transit joint of the guide rod and vibrating impacter that connect vibro replacement stone column machine, and it comprises: the rubber absorbers 201 in tubular; Be embedded in the upper adpting flange 202 for connecting guide rod on rubber absorbers 201 top; Be embedded in the lower adpting flange 203 for connecting transit joint of rubber absorbers 201 bottom; Wherein, the bonding surface of upper adpting flange 2 and guide rod is provided with hermetically-sealed construction; Wherein, the bonding surface of lower adpting flange 203 and transit joint is provided with lower seal structure.
Bumper assembly of the present utility model, has following difference: in shape compared with the damper in prior art vibrating impacter, no longer adopts the structure of circular platform type, but adopts cylindrical structure; When making, no longer adopt traditional damper be made up of the mode of steel sheet inside casting rubber, but employing directly makes damper by the elastomeric material of high strength, simplify production process, and, in manufacturing process, upper and lower adpting flange is placed in mould by predeterminated position, castable rubber is adopted to form rubber absorbers again in mould, thus obtain upper and lower adpting flange and be embedded in structure in rubber absorbers and integrally formed with it, greatly increase the bonding strength of upper and lower adpting flange and rubber absorbers, improve the application life of damper; In addition, the bonding surface of upper and lower adpting flange and guide rod and transit joint is respectively arranged with upper and lower hermetically-sealed construction, thus improves the reliability of bonding surface place sealing, improve the damping effect of damper.
Concrete, as shown in Figure 1, in the utility model bumper assembly, the bonding surface of upper adpting flange 2 and guide rod is provided with hermetically-sealed construction, and it comprises: the cannelure 204 being arranged on adpting flange 202 top; Be placed in the upper sealing ring (not shown) in cannelure 204, wherein, upper sealing ring is O-ring seals.Sealed by the bonding surface of O-ring seals by upper adpting flange and guide rod, improve the sealing at bonding surface place.
In addition, the bonding surface of lower adpting flange 203 and transit joint is provided with lower seal structure (not shown), and this lower seal structure is identical with upper hermetically-sealed construction, no longer repeats at this.
Further, bumper assembly of the present utility model also comprise be embedded in rubber absorbers 201 for improving cord 208 in rubber absorbers tension and anti-twisting property, it is combined by nylon rope and steel wire and makes, be embedded on arbitrary cross section of rubber absorbers, preferably, interior cord is embedded in rubber absorbers and is positioned on middle cross section.By interior cord is embedded in rubber absorbers inside, substantially increases tension and the anti-twisting property of damper, avoid the damage to connected guide rod, and cable, water pipe and the wire rope that is connected with guide rod are played a protective role.
Further, as shown in Figure 1, bumper assembly of the present utility model also comprises the tensile structure being embedded in adpting flange 202 and/or lower adpting flange 203 and rubber absorbers 201 bonding surface place, and this tensile structure comprises: the screwed hole 209 being preset in the horizontal integration face place of adpting flange 202 and/or lower adpting flange 203 and rubber absorbers 201; And be embedded in the interior swivel nut 210 at adpting flange 202 and/or lower adpting flange 203 and longitudinal bonding surface place of rubber absorbers 201.
By presetting screwed hole at the bonding surface place transversely of rubber absorbers and upper and lower adpting flange, when upper and lower adpting flange can be made to be connected with guide rod and transit joint respectively, directly upper adpting flange, guide rod and rubber absorbers can be connected as one by screw, and by screw, rubber absorbers and lower adpting flange, transit joint are connected as one, thus installation or removal are convenient, be convenient to maintenance, and, screwed hole is preset in rubber absorbers, improves the bonding strength connecting upper and lower adpting flange and guide rod and transit joint.
In addition, at rubber absorbers and upper and lower adpting flange bonding surface place is longitudinally also embedding interior swivel nut, thus add the bond area of rubber absorbers and upper and lower adpting flange, improve the pressure-resistant seal between rubber absorbers and two adpting flanges and tension sealing performance.Upper and lower adpting flange of the present utility model is connected with guide rod or transit joint by screw, can increase the damping cross section on damper cross section, improves damping effect.
Wherein, as shown in Figure 1, the utility model is at the inner also embedding pre-embedded bolt 211 had for being connected as one with upper adpting flange 202 and lower adpting flange 203 respectively in its top and bottom of rubber absorbers 201.Preferably, the nut of pre-embedded bolt 211 and upper adpting flange 202 or lower adpting flange 203 junction are provided with preset flange 212.By pre-embedded bolt 211, add the bonding strength between rubber absorbers and upper and lower adpting flange, and improve the damping effect of rubber absorbers.
It should be noted that, bolt 211 in the utility model, preset flange 212, interior swivel nut 210 are embedded in rubber absorbers respectively, namely, in manufacturing process, above-mentioned parts are the same with upper and lower adpting flange, all be well placed in mould, then by castable rubber in mould, make above-mentioned each parts shape all-in-one-piece rubber absorbers together with rubber.By changing structure and the manufacture craft of traditional shock absorber, substantially increasing the damping effect of the utility model bumper assembly, the exciting force of vibrating impacter when shaking punching operation being decayed rapidly, relieving the destruction that vibrating impacter vibration force causes guide rod and lifting appliance.
From the above, bumper assembly of the present utility model, tension, antitorque, pressure-resistant seal performance are better, and damping effect is outstanding, and application life is also longer, can reduce the maintenance to bumper assembly, change man-hour, thus can enhance productivity.
Although be explained in detail the utility model above; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
