Abstract

The utility model discloses a vibratory hammer pile machine eccentric device which comprises a transmission shaft, an eccentric gear, a semicircular eccentric block, a key, a countersunk bolt and a cylinder cup, wherein the cylinder cup is fixedly sleeved outside the eccentric block to form a combined piece; the inner diameter of the cylinder cup is identical to the diameter of the eccentric block; the depth of the cylinder cup is equal to the length of the eccentric block so that the rotary shafts of the cylinder cup and the eccentric block are the same; the key is firstly embedded into the transmission shaft, the combined piece of the cylinder cup and the eccentric block is assembled in a preset position of the transmission shaft, furthermore the eccentric gear is also assembled in the preset position of the transmission shaft, the countersunk bolt is inserted between the eccentric block and the combined piece, the eccentric block and the eccentric gear are fastened together, and the opening of the cylinder cup is adhered to the eccentric gear. By adopting the vibratory hammer pile machine eccentric device, on premise that the property of a vibratory hammer is not changed, the defects that the hammer body is easy to heat up and a pile machine is poor in continuous working reliability can be overcome.

Description

Vibrating hammer stake machine eccentric
Technical field
The utility model relates to building piling machinery equipment, is specifically related to high-frequency hydraulic hammer stake machine eccentric.
Background technology
High-frequency hydraulic hammer has that noise is low, speed of application is fast, can sink the advantages such as pile pulling operation, boundary of works area be wide, be applicable to the construction of the multiple stake such as steel pipe pile, fully-sleeved filled pile, steel sheet pile, thin-walled cylinder pile type, in the engineerings such as building construction at home and abroad, port and pier, treatment of soft foundation, be used widely.Existing high-frequency hydraulic hammer is domestic high-frequency hydraulic hammer particularly, generally formed by power transmission shaft, eccentric gear, semicircle eccentric block, key and dormant bolt, this structural vibration hammer stake machine eccentric exists that hammer body easily generates heat, the defect of stake machine continuous operation poor reliability, by analysis, hammer body easily the main cause of heating be eccentric block semicircle or fan-shaped in vibrating hammer casing in the time of High Rotation Speed, can fierce bounce with agitated vibrations casing in lubrication oil, cause the problems such as steering resistance is large, lubrication oil heating.
Summary of the invention
The purpose of this utility model is to provide a kind of vibrating hammer stake machine eccentric, is keeping under the constant prerequisite of vibrating hammer performance, overcomes that hammer body easily generates heat, the defect of stake machine continuous operation poor reliability.
For realizing above object, the utility model vibrating hammer stake machine eccentric comprises power transmission shaft, eccentric gear, semicircle eccentric block, key, dormant bolt and cylinder cup, described cylinder cup fixed cover forms composite member in eccentric block outside, cylinder cup internal diameter is identical with eccentric block diameter, the cylinder cup degree of depth and eccentric block are equal in length, make both gyroaxises consistent; First sunk key on power transmission shaft, the composite member of cylinder cup and eccentric block is assembled to power transmission shaft precalculated position, again eccentric gear is also assembled to power transmission shaft precalculated position, between eccentric block and eccentric gear, insert dormant bolt, eccentric block and eccentric gear are tightened together, and the rim of a cup of cylinder cup is pressed close to eccentric gear.
Said structure vibrating hammer stake machine eccentric, because eccentric profile is cylindric, does not have raised face, in the time of High Rotation Speed, can effectively avoid bouncing and stirring lubrication oil, has following beneficial effect:
1, high speed rotary resistance is little, avoids fierceness to bounce and stir lubrication oil.
2, oil temperature raises slowly, reduces the heat-resisting requirement to hammer body hydraulic system or extends its life-span.
3, reduce energy consumption.
Brief description of the drawings
Fig. 1 is that prior art vibrating hammer stake machine eccentric master looks schematic diagram;
Fig. 2 is that schematic diagram is looked on the right side that prior art vibrating hammer stake machine eccentric removes after power transmission shaft and key;
Fig. 3 is that the utility model vibrating hammer stake machine eccentric master looks schematic diagram;
Fig. 4 is that schematic diagram is looked on the right side that the utility model vibrating hammer stake machine eccentric removes after power transmission shaft and key.
In figure: power transmission shaft 1, eccentric gear 2, semicircle eccentric block 3, key 4, dormant bolt 5, cylinder cup 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model vibrating hammer stake machine eccentric is described in further detail:
The vibrating hammer of the utility model shown in Fig. 3～Fig. 4 stake machine eccentric comprises power transmission shaft 1, eccentric gear 2, semicircle eccentric block 3, key 4, dormant bolt 5 and cylinder cup 6, described cylinder cup 6 is enclosed within eccentric block 3 outsides, both are welded together to form composite member, cylinder cup internal diameter is identical with eccentric block diameter, the cylinder cup degree of depth and eccentric block are equal in length, make both gyroaxises consistent; Sunk key 4 on power transmission shaft 1, adjust position, the composite member of cylinder cup 6 and eccentric block 3 is assembled to power transmission shaft 1 precalculated position, again eccentric gear 2 is also assembled to power transmission shaft 1 precalculated position, between eccentric block 3 and eccentric gear 2, insert dormant bolt 5, eccentric block 3 and eccentric gear 2 are tightened together, and the rim of a cup of cylinder cup 6 is pressed close to eccentric gear 2.
When this vibrating hammer stake machine eccentric work, engaged with eccentric gear 2 by another gear that power is provided, and drive eccentric gear 2 High Rotation Speeds, eccentric gear 2 is by the connection of key 4 and dormant bolt 5, drive eccentric block 3 and cylinder cup 6 High Rotation Speeds, because the barycenter of eccentric block 3 is not on center of rotation, when High Rotation Speed, certainly lead to larger centrifugal force, on high-frequency hydraulic hammer stake machine, this eccentric generally uses in pairs, the centrifugal force of its horizontal direction is cancelled out each other, the centrifugal force of vertical direction obtains stack strengthening, because of the centrifugal force of eccentric paired in hammer body up and down, vibrating hammer produces the exciting force of up-down vibration thus, because eccentric profile is cylindric, there is no raised face, in the time of High Rotation Speed, can effectively avoid bouncing and stirring lubrication oil, therefore can keep under the constant prerequisite of vibrating hammer performance, overcome that hammer body easily generates heat, the defect of stake machine continuous operation poor reliability.
