Abstract
The invention discloses a kind of steel tube damping devices, including bottom plate, rectangle cylinder, rectangle plunger, pre- cartridge screw, steel pipe；Steel tube damping device is installed on pedestal by the mounting hole on bottom plate, it is connected by top plate with equipment, steel pipe is orderly laid in the working chamber of steel tube damping device in advance, when steel tube damping device works, the steel pipe squeezed in working chamber is moved downward by rectangle plunger, and make to generate extruding and opposite fricting movement between steel pipe, the vibrational energy of equipment is absorbed and consumed, effective cushioning effect is played.Since steel tube damping device is all-metal structure, does not need to carry out daily maintenance, reduce the use cost of damper, improve the service life of damper.A kind of steel tube damping device proposed by the present invention can also be applied to the antidetonation shock attenuation of bridge and building.
Description
Technical field
The present invention relates to a kind of dampers, and in particular to arrive a kind of steel tube damping device, belong to vibration and electrically with electromechanical skill
Art field.
Background technique
The equipments such as motor, diesel engine, steam turbine, blower during the work time, inevitably generate vibration, and vibration
Pass to installation foundation, while influencing the working performance of equipment, at present, it is common to use method be to add rubber pad or make
Damping is carried out with hydraulic damper, viscous damper, for hydraulic damper, viscous damper, needs to carry out regular
Maintenance work, and the service life of rubber pad is shorter.
Summary of the invention
In order to solve this problem, the invention proposes a kind of steel tube damping devices.
Technical scheme is as follows:
A kind of steel tube damping device, characterized by comprising: bottom plate, rectangle cylinder, rectangle plunger, pre- cartridge screw, steel pipe；
The top edge of the rectangle cylinder is equipped with shell flange；
The upper end of the rectangle plunger is top plate, and middle part is plunger body, and lower end is plunger bottom plate, and the upper end is top plate, column
Cock body and plunger bottom plate are integrally welded, organize rectangularity plunger；
The lower end of the rectangle cylinder and bottom plate are integrally welded；
The lower part of rectangle cylinder lumen is placed in front of and after the steel pipe to ordered arrangement, forms the accumulation body of several layers steel pipe；
The length of the steel pipe is less than the anteroposterior dimension of rectangle cylinder lumen；
The rectangle plunger insertion is installed to the inner cavity of rectangle cylinder, and the lower end surface of plunger bottom plate pushes against the accumulation of steel pipe
Body forms working chamber A, is placed in front of and after steel pipe to ordered arrangement between the lower end surface of plunger bottom plate and the inner cavity of rectangle cylinder
In working chamber A, the inner wall formation of the outer wall and rectangle cylinder of plunger body and plunger bottom plate is slidably matched, and rectangle plunger is opposite
It can be realized and move up and down in rectangle cylinder；
The rectangle plunger is connected with each other by pre- cartridge screw and rectangle cylinder；
The steel tube damping device is installed on pedestal by bottom plate, is attached by top plate and associated equipment；
The pre- cartridge screw is removed after steel tube damping device completes in-site installation.
The diameter and wall thickness of above-mentioned steel pipe require to be adjusted according to concrete application.
Beneficial effects of the present invention are as follows:
The present invention includes bottom plate, rectangle cylinder, rectangle plunger, pre- cartridge screw, steel pipe；Steel tube damping device passes through on bottom plate
Mounting hole is installed on pedestal, is connected by top plate with equipment, orderly lays steel in the working chamber of steel tube damping device in advance
Pipe when steel tube damping device works, moves downward the steel pipe squeezed in working chamber by rectangle plunger, and make to generate between steel pipe
It squeezes and opposite fricting movement, the vibrational energy of absorption and consumption equipment plays effective cushioning effect.Due to steel tube damping
Device is all-metal structure, does not need to carry out daily maintenance, reduces the use cost of damper, and improve damper uses the longevity
Life.A kind of steel tube damping device proposed by the present invention can also be applied to the antidetonation shock attenuation of bridge and building.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.

The rectangle plunger 3 is inserted into the inner cavity for being installed to rectangle cylinder 2, and the lower end surface of plunger bottom plate 3-3 pushes against steel pipe 5
Accumulation body, forms working chamber A between the lower end surface of plunger bottom plate 3-3 and the inner cavity of rectangle cylinder 2, the front and back of steel pipe 5 is to orderly
Arrangement is placed in working chamber A, and the inner wall formation of the outer wall and rectangle cylinder 2 of plunger body 3-2 and plunger bottom plate is slidably matched,
Rectangle plunger 3 can be realized relative to rectangle cylinder 2 and move up and down；
The rectangle plunger 3 is connected with each other by pre- cartridge screw 4 and rectangle cylinder 2；
The steel tube damping device is installed on pedestal by bottom plate 1, is attached by top plate 3-1 with associated equipment；
The pre- cartridge screw 4 is removed after steel tube damping device completes in-site installation.
