The utility model has the advantages of little self-energy loss of the pile hammer, firm overall structure, increased design strength of the vulnerable areas, easy installation and detachment, convenient maintenance, and low failure rate.
Description
The utility model relates to the shocks pile driver in the piling machinery and needs the engineering machinery of vibratory impulse, is a kind of vibrohammer that is applicable to heavy pile pulling of vibration and vibrator pipe sinking cast-in-place pile construction.
Vibrohammer that the utility model provides and DZ-KS of the prior art series vibrohammer (GB8517-87) and the disclosed two kinds of vibrohammers of Chinese patent CN2134432Y, CN2285792Y belong to same type, all be by the Motor Drive vibrator works, shock absorber adopts cylindroid helical-coil compression spring, and the eccentric hammer Phase synchronization is by synchromesh gear control.
All there is following defective with electric motor driven vibrohammer in the prior art:
1, motor is fixedly mounted on vibrator casing or the casing, is connected as a single entity and vibrates with it with vibrator, and the vibrating body quality, the amplitude that have therefore increased complete machine reduce, and motor is fragile.
2, two of shock absorber springs one positive are negative is suspended in vibrator between two springs.Vibrohammer 4～8 shock absorbers usually in parallel, spring precompressed stroke is long during assembling, pressure is big, is equivalent to 80～90% of single length of spring compressed total amount, and the spring of whole vibration insulating system needs compression synchronously or stretching, extension, installation, dismounting all need large-scale special tool, operating difficulties and dangerous.
3, synchromesh gear is in eccentric hammer is installed in vibrator case shell, and mounting or dismounting all need large-scale lifting appliance, and workload is big, and maintenance and inspection are very inconvenient.
4, vibrator speed of mainshaft height, load is heavy, so bearing is shorter application life.
The real novel purpose of this usefulness is to propose a kind of improved vibrohammer, and it can effectively alleviate oscillating mass, improves the mounting or dismounting maintainability and increases the service life.
The purpose of this utility model realizes by following technical measures: the vibrohammer structure comprises electric motor driven vibrator, parts such as spring cushion and vibration damping beam, its feature.
Motor mounting on the hinge type motor base, motor base be installed in the rigidly connected flap seat of vibration damping beam on; Vibrator is connected with the damper spring axle and is suspended under the vibration damping beam; Vibrator drive axis and electric-motor drive wheel axis are parallel to each other and are located in the same horizontal plane.
Described hinge type motor base is made of seat board, hinge and flexible adjustment device, and motor mounting is on seat board; Shock absorber is installed in the vibration damping beam.Shock absorber is made of the axle sleeve of spring up and down of spring shaft that is set with a spiral compression spring and envelope pressing spring.
Embodiment and accompanying drawing thereof below in conjunction with utility model are described further.
Fig. 1 is the structural representation of the vibrohammer that the utility model proposes.Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is the C-C sectional drawing of vibrator 1.Fig. 4 is the structure enlarged diagram of shock absorber 2.
As shown in Figure 1, vibrator 1 is connected shock absorber 2 belows, shock absorber is installed in the vibration damping beam 3, the running wheel of carrying on vibration damping beam top links to each other with lifting appliance by wire rope, flap seat 9 is equipped with in the left and right sides, hinge type motor base 8 is housed on the flap seat, and this base is made of seat board 8-1, hinge 8-2 and flexible adjustment device 8-3, and motor mounting is on seat board.Vibrator drive 4 axis and electric-motor drive are taken turns 5 axis with occuping on the horizontal plane of A-A line.Generally in 10mm, wheelbase changes less than 0.1mm amplitude between motor 7 and the vibrator at this moment during the vibrator vibration, and motor is a relative static conditions; And when vibrator because of the pile sinking (pipe) that resonates, pressurizes, hale pile pulling (pipe) etc. when the B-B direction produces displacement by a relatively large margin or move back and forth, flexible adjustment device on the hinge type motor cabinet can make motor do corresponding swing, with the distance between automatic maintenance principal and subordinate movable belt pulley and the tensile force of driving-belt.Motor is not contained on the vibrator casing, has both made vibrator weight saving, and self energy consumption reduces during vibration, has avoided motor with one high vibration of vibrator again.
As shown in Figure 2, directive wheel 6 be installed in the rigidly connected flap seat of vibration damping beam on, directive wheel is static relatively when vibrator vibrates, and has avoided the bump guide rail to produce noise and wearing and tearing.
As shown in Figure 3, synchromesh gear 1-6 is installed in the case shell rear wall plate outside of vibrator, is positioned at gear-box 1-7 and is sealed by case lid 1-8, takes off case lid and can check more gear changing.
The vibrator cabinets cavity has inner wall panel 1-4 with spaced apart around eccentric hammer 1-3 apron space and the bearing 1-5, and when eccentric hammer was rotated at a high speed, lubrication oil was drained in bearing and surrounding space and the gear-box in the case, and bearing and gear obtain sufficient lubrication.Because eccentric hammer rotary space lubrication oil impacts the lubrication oil consumption energy and makes oily temperature rise when seldom, having reduced the eccentric hammer running.
The supporting of four pairs of bearings arranged on the every main shaft 1-2 of vibrator, alleviated the load on every pair of bearing effectively, help prolonging bearing application life.Be separated with lining 1-9 between main bearing seat hole on the vibrator casing and the bearing, make things convenient for installation, dismounting and the maintenance of main shaft and bearing.
As shown in Figure 4, shock absorber 2 is made of spring shaft 2-1, spring axle sleeve 2-2 and a cylindroid helical-coil compression spring 2-3, is installed in the vibration damping beam 3, and spring shaft lower end and vibrator housing are rigidly connected.When spring shaft moved back and forth with vibrator, the spring axle sleeve of respective end is the sliding compression spring vertically, realized vibration damping and accumulation of energy.Every vibrohammer symmetry is installed 6～12 shock absorbers.The assembling precompressed amount of this damper spring is very little, need not the special tool mounting or dismounting, rapid operation safety.
Characteristics such as it is little to the utlity model has the vibrating body quality, and motor is relative with directive wheel static during the pile monkey vibration, and the loss of pile monkey self-energy is few, and overall structure is firm, and the damageable zone design strength increases, and mounting or dismounting easily, and are easy to maintenance, and fault rate is low.
