Description
Technical field
The present invention relates to the foundation construction field of mechanical technique, particularly a kind ofly be applicable to that building or structure ground stabilization are with the squeezing into and extract of pile tube, H pile, sheet pile class piling bar and concrete precast pile, and the vibrohammer of the inner disposed upright formula of the band eccentric moment adjusting mechanism used of system cast-in-place concrete pile.
Background technology
Since entering the nineties in 20th century, the adjustable vibrohammer manufacturing technology of eccentric moment stepless continuous has obtained large development, there is the product of multiple model in major infrastructure project, to use, produced good society, economic benefit, but a fly in the ointment is that set eccentric moment adjusting mechanism is independent external on existing this series products, all be that realize the additional below that is arranged on diaxon vibrohammer or four pile monkey casing outside synchromesh gears, profile as shown in Figure 1, be equivalent on diaxon vibrohammer or four pile monkey bases, set up one, produced three or five appearance effect, cause volume to increase, overall size is higher and the oeverall quality change is heavy, convenience variation when causing using, working amplitude reduces, consumptive material increases and the assembly working amount increases, and the overall manufacturing cost is higher.So general structure is still owed rationally, consider still to owe desirable from practicality and economy angle.
Summary of the invention
The objective of the invention is to provide a kind of general structure compact and rationally, oeverall quality is light, consumptive material is few and stable performance, help reducing production costs and improve the vibrohammer of the inner disposed upright formula of the band eccentric moment adjusting mechanism of ease of use.
The vibrohammer main body of the inner disposed upright formula of band of the present invention eccentric moment adjusting mechanism includes the power drive input link, the vibrator casing, biaxially oriented inertia vibrator in the left and right sides and eccentric moment adjusting mechanism, the biaxially oriented inertia vibrator in the left and right sides is arranged in the vibrator casing, by the driving shaft and the driven shaft that are arranged on the left and right sides bearing supporting on the end plate of vibrator casing front and back, by needle bearing respectively movable set be arranged on axle sleeve A and axle sleeve B on driving shaft and the driven shaft, be fixedly installed on driving shaft respectively in pairs, preamble gear A and preamble gear B on driven shaft and described axle sleeve A and the axle sleeve B, back synchromesh gear A and back synchromesh gear B, and include the pre-eccentric body A that is arranged in pairs on the driving shaft, back eccentric body A and the pre-eccentric body B that is arranged in pairs on the driven shaft, four pairs of eccentric bodies of back eccentric body B constitute, it is characterized in that: described eccentric moment adjusting mechanism main body is arranged in the vibrator casing, including a pair of the extension respectively is arranged on driving shaft and driven shaft and is positioned at big helical pitch helical spline shaft part A and big helical pitch helical spline shaft part B on the tail end of the outside, bearing supporting position, the left and right sides, it is opposite to be respectively arranged with rotation direction on a pair of main body domestic and foreign work face, meshing suit respectively is arranged on described a pair of big helical pitch helical spline shaft part A and the big helical pitch helical spline shaft part B, afterbody overlaps B (be called for short and adjust cover) with helical spline adjustment cover A and the helical spline adjustment of non-splined end A and non-splined end B respectively, a pair of being set with on the main body external surface that is arranged on described a pair of helical spline adjustment cover A and helical spline adjustment cover B, inlay and be arranged in a pair of synchronous carrier gear A and the synchronous carrier gear B hole, and by bearing spacing big helical pitch helical spline cover A and big helical pitch helical spline cover B, and by the non-splined end A that is separately positioned on described helical spline adjustment cover A and helical spline adjustment cover B and thrust bearing in the non-splined end B chamber and stepped little axle, nut with cover and the bearing support placed outward, for the gusset piece that connects described stepped little axle one end, and the regulation device that is arranged on the hydraulic jack formation between casing back shroud and the gusset piece, the piston rod fixed installation of wherein said hydraulic jack is arranged on the described gusset piece, and the fixed installation of the cylinder body of hydraulic jack is arranged on the casing back shroud.
During work, the piston rod that described gusset piece is controlled by on the hydraulic jack is done displacement up and down, and stepped little axle is controlled by gusset piece and does displacement up and down.When to the big chamber of hydraulic jack fuel feeding, piston rod stretches out, promote the gusset piece upward displacement, gusset piece drives on the stepped little axle and moves simultaneously, by thrust bearing drive adjustment non-splined end A of cover and non-splined end B helical spline adjustment cover A and B are pulled out, can pull out 1/8 lead of screw at most, order about the big helical pitch helical spline shaft part A that is meshed with its domestic and foreign work face and big helical pitch helical spline shaft part B drives driving shaft respectively and driven shaft rotates in this process that helical spline adjustment cover A and B are drawn out, two biaxially oriented inertia vibrators are done the both forward and reverse directions rotation about making.When driving shaft and driven shaft rotate to an angle, be meshed, so make two synchronous carrier gear A and synchronous carrier gear B can only rotate and to move axially with synchronous carrier gear A and synchronous carrier gear B.When regulation device was in off working state, the anglec of rotation was zero, and two vibrators are in free state, and all perpendicular to axle below and axially coincidence, the eccentric moment value under this state is maximum to the eccentric body barycenter; When regulation device is worked, along with stretching out gradually of piston rod, eccentric moment will increase gradually and reduce along with the anglec of rotation, and during the anglec of rotation to 180 °, eccentric moment is zero.So, as desire eccentric moment is turned down, then should extract and adjust cover, extracting peak discharge is 1/8 of helical spline helical pitch, this moment, eccentric moment was zero.In addition, when regulation device be in off working state, when adjusting cover and being failure to actuate, the power of vibrator is imported by the power drive input link, drive the adjustment cover by driving shaft, through synchronous carrier gear, and then two vibrators are done the both forward and reverse directions rotation about ordering about, and vibrohammer is worked under maximum eccentric moment.
Vibrohammer based on the inner disposed upright formula of the band of the present invention eccentric moment adjusting mechanism of above-mentioned design, owing to big helical pitch helical spline shaft part is set by continuity on driving shaft and driven shaft, and suit is provided with that domestic and foreign work face is provided with the opposite helical spline adjustment cover of big helical pitch rotation direction and tightens to be sticked at the bonnet of vibrator casing and puts the method for regulation device on the big helical pitch helical spline shaft part, eccentric moment adjusting mechanism is arranged on the vibrator box house rearward position, and directly link to each other with driven shaft with driving shaft, though make the slightly expansion backward of vibrator casing, but because structure is quite compact, many weak points of existing external addition type vibrohammer have effectively been overcome, thereby vibrohammer of the present invention is compared with existing any a vibrohammer with external addition type eccentric moment adjusting mechanism, it is little obviously to have volume, in light weight, labor and material saving during manufacturing, plurality of advantages such as product cost is low and easy to use have tangible technical advance, very strong practicality and wide market application prospect.
