Detailed description of the invention
Fig. 1 is the structural schematic diagram of Bridge Pile Foundation Construction vibration proof device provided by the utility model;
Fig. 2 is the sectional view of Anti-vibration unit provided by the utility model.
Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein Example only to explain the utility model, is not used to limit the utility model.
The utility model provides a kind of Bridge Pile Foundation Construction vibration proof device, can be effectively reduced drilling tool in boring procedure Vibration, thus guarantee drill bit drilling when not run-off the straight, guarantee borehole accuracy.
With reference to Fig. 1, including support pedestal 1, support pedestal 1 is the body structure of lower openings, inner hollow, supports pedestal 1 back-off in it is hole to be drilled above the ground, can be used screw rod will support pedestal 1 surrounding be fixed on ground;It installs at the top of drilling rod 2 Drilling machine 3, the bottom of drilling rod 2 extend to the inside of steel pile casting 4 after the assembly through-hole that support pedestal 1 opens up, and in drilling rod 2 Bottom end is installed by drill bit 5;Wherein, rubber washer 6, rubber washer are installed in the assembly through hole that drilling rod 2 and support pedestal 1 are in contact With certain elasticity, to reduce the vibration of drilling tool to a certain extent;Drilling rod 2 is fixedly mounted in the position close to top to be subtracted Shake cross bar 7;Left damping telescope support 8 is installed between the left side of damping cross bar 7 and the top for supporting pedestal 1;The right side of damping cross bar 7 Right damping telescope support 10 is installed between side and the top for supporting pedestal 1;In drilling tool boring procedure, drilling machine 3 drives 2 turns of drilling rod It is dynamic, and then drill bit 5 is driven to carry out the downward drilling process of straight line, in drilling process, damping cross bar 7 is transported downwards with drilling rod 2 Dynamic, to compress the damping telescope support of two sides, damping telescope support is located at the left and right sides of drilling rod 2, and acting on has two o'clock: the One, the vibration that drilling rod 2 generates in drilling process passes to damping telescope support by damping cross bar 7, realizes certain vibration damping Effect;Second, damping telescope support has certain supporting role to drilling rod 2, prevents drilling rod 2 in drilling process with certain In inclined effect, guarantee borehole accuracy.
Anti-vibration unit 9 is installed in the inside of support pedestal 1;With reference to Fig. 2, Anti-vibration unit 9 includes vertical rack 9.1, gear 9.2, crank 9.3, connecting rod 9.4, piston 9.5 and Barrel of Hydraulic Cylinders 9.6;Vertical rack 9.1 is arranged vertically within the interior of support pedestal 1 Wall;Vertical rack 9.1 is engaged with gear 9.2;Gear 9.2 is engaged with crank 9.3;Barrel of Hydraulic Cylinders 9.6 is horizontally set at support The inside of pedestal 1;The inside of Barrel of Hydraulic Cylinders 9.6 is installed by the piston 9.5 that can be slid laterally;One end of connecting rod 9.4 and crank 9.3 Connection, the other end of connecting rod 9.4 are connect with piston 9.5.Its working principle is that: when drilling tool vibrates in drilling process, Vibration passes to support pedestal 1, and support pedestal 1 drives vertical rack 9.1 to carry out upper and lower when carrying out the vibration of up and down direction To vibration, 9.1 up and down direction of vertical rack move when band moving gear 9.2 rotate;Since gear 9.2 and crank 9.3 engage, because This, gear 9.2 drives crank 9.3 to rotate;When crank 9.3 rotates, drive piston 9.5 in Barrel of Hydraulic Cylinders by connecting rod 9.4 Straight reciprocating motion is carried out in 9.6, to realize effectiveness in vibration suppression.
The Anti-vibration unit formed using crank link mechanism cleverly will support the vibration motion of pedestal up and down direction to convert For the linear motion in the horizontal direction of piston 9.5, on the one hand, realize effectiveness in vibration suppression;On the other hand, Anti-vibration unit is laterally to set The mechanism set, rather than vertically arranged mechanism, so, whole device reduces drilling rod and is located in the small volume of vertical direction The intracorporal height of support base occupies, and improves the utilization rate of drilling tool.
In addition, the outer wall of drilling rod and drill bit can generate a large amount of frictional heat, to drop since drilling tool is in boring procedure Low drilling tool service life.Therefore, in the application, there is through-hole 2.1 at the center of drilling rod 2, the top of drilling rod 2 have for The water injection hole 2.2 of through-hole water filling.So injecting water in drilling tool boring procedure into through-hole 2.1 by water injection hole 2.2, can having Effect cools down to drilling tool.
Bridge Pile Foundation Construction vibration proof device provided by the utility model has the advantage that
The utility model provides a kind of Bridge Pile Foundation Construction vibration proof device, can be effectively reduced drilling tool in boring procedure Vibration, thus guarantee drill bit drilling when not run-off the straight, guarantee borehole accuracy.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching should also regard the protection scope of the utility model.
