Description

Technical Field

[0001] The utility model relates to the technical field of pile planting, in particular to a double-slide static drilling root pile device. Background Art

[0002] The static pressure piling device is a key component of a piling driver. Using a single device, a piling driver can complete both drilling and piling, which helps improve the coaxiality of the pipe during piling and the drilled hole, thereby increasing piling efficiency. The static pressure piling device primarily comprises a frame, a lifting seat, a clamping block, a horizontal drive that drives the clamping block to clamp or release the pipe, and a lifting drive that drives the lifting seat up and down for static pressure piling. The lifting seat has a clamping channel in the middle for inserting pipes, and the clamping block is movably positioned within the clamping channel. A horizontal drive is mounted on the lifting seat, with the drive shaft fixedly connected to the clamping block. The lifting drive is mounted on the frame, with the drive shaft connected to the lifting seat. The lifting seat and frame are guided by a pulley.

[0003] The pipe fittings need to be hoisted by a crane to the middle of several clamping blocks. During the hoisting movement, the pipe fittings are prone to shaking and deviating from the clamping center of the clamping blocks. If the pipe fittings collide with the lifting seat during the descent, the collision force will cause the lifting seat to vibrate, and the force will be transmitted to the frame through the pulley, causing the entire static pressure pile device to vibrate, which can easily damage the pulley and affect the service life of the static pressure pile device.

[0004] This case arises in order to solve the above problems. Utility Model Content

[0005] Therefore, in order to solve the above problems, the present invention proposes a dual-slide static drilling root pile device.

[0006] The lifting mechanism is a pair of fixedly mounted on-ramps, each of which is connected to the support frame of the lifting base, and the supporting ram is connected with the support frame of the lifting base to connect the lifting mechanism, and the supporting ram is connected with the support frame of the lifting base to connect the lifting mechanism.

[0007] The vibration absorbing guide wheel assembly includes a guide rail, a mounting seat, a mounting shaft, a bushing, a vibration absorbing wheel, and an open positioning ring, the mounting seat is fixedly arranged on the upper surface and / or lower surface of the lifting seat, the lifting seat is provided with a rotating groove for the vibration absorbing wheel to be embedded in and rotatably arranged, the lifting seat is located on both side walls of the rotating groove and is provided with a mounting channel connected to the rotating groove, both ends of the mounting shaft are passed through the mounting channel, the vibration absorbing wheel is fixedly arranged on the outer surface of the bushing, the bushing is rotatably sleeved on the middle section of the mounting shaft, the outer surface of the mounting shaft is located at both ends of the bushing and has positioning grooves circumferentially opened, the open positioning ring is clamped in the positioning groove, the two side surfaces of the open positioning ring are respectively in contact with the side surface of the bushing and the side wall of the positioning groove, the guide rail is vertically fixedly arranged on the surface of the column, and the outer surface of the vibration absorbing wheel is in contact with the surface of the guide rail.

[0008] A further improvement is that a curved protrusion is vertically fixed in the middle of the guide rail surface for assisting the vibration absorbing wheel in absorbing axial vibration force, and a curved annular groove is provided in the middle of the outer surface of the vibration absorbing wheel for the curved protrusion to extend into and fit into.

[0009] A further improvement is that a metal ring is provided inside the vibration absorbing wheel for preventing the vibration absorbing wheel from deforming to improve the buffering effect, and the cross section of the metal ring is an arc convex toward the outer surface of the vibration absorbing wheel.

[0010] Further improvements are: an oil storage cavity is opened inward from one end face of the mounting shaft, a rubber plug for closing the oil storage cavity is provided in the port of the oil storage cavity, an oil outlet groove is opened circumferentially on the outer surface of the mounting shaft, an oil outlet channel is opened at the bottom of the oil outlet groove and connected to the oil storage cavity, a lubrication groove for lubricating oil to enter is spirally opened on the inner surface of the sleeve, and the lubrication groove is connected to the oil outlet groove.

[0011] A further improvement is that an oil filling gap is provided in the middle of the rubber plug for inserting a needle for oil filling and the gap is self-sealed after the needle is pulled out.

[0012] A further improvement is that a driving rod is provided on the other end face of the installation shaft along the vertical axial direction, the fixed end of the driving rod is fixedly sleeved on the installation shaft, and a driving block is rotatably provided on the outer side of the free end of the driving rod.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] The lifting base and the frame's columns are flexibly connected via a vibration-absorbing guide assembly. The vibration force generated by the pipe striking the lifting base is transmitted to the frame through the vibration-absorbing guide assembly. In this case, the vibration-absorbing guide assembly comprises two sets of vibration-absorbing guide wheels. The guide tracks of these two sets of vibration-absorbing guide wheels form mutually perpendicular dual slideways on the inner sides of the columns. These two sets of vibration-absorbing guide wheels work together to buffer the horizontal vibration force generated by the pipe striking the lifting base, reducing the impact of the impact on the lifting base and frame.

[0015] In this case, the vibration absorbing wheel is rotatably connected to the mounting shaft through a bushing, rather than a bearing, which is beneficial to improving the impact resistance of the vibration absorbing guide wheel group and extending the service life of the vibration absorbing guide wheel group.

[0016] A further beneficial effect is that before the arc-surface protrusion and the arc-surface annular groove are provided, the surface of the vibration-absorbing wheel and the surface of the guide track are in straight-line contact, and the axial vibration force of the vibration-absorbing wheel is buffered and absorbed by another set of vibration-absorbing guide wheel groups that are perpendicular to it. The vibration-absorbing wheel can only buffer and absorb the vibration force in a single direction perpendicular to the axial direction, cannot play a good vibration-absorbing role, and is prone to damage to the vibration-absorbing guide wheel group.

[0017] Therefore, in this case, an arc-shaped protrusion is set on the surface of the guide rail, and an arc-shaped annular groove is set on the surface of the vibration-absorbing wheel. The vibration-absorbing wheel and the arc-shaped surface of the guide rail are flexibly fitted together. No matter from which angle the pipe hits the lifting seat, the surface of the vibration-absorbing wheel can be squeezed and fitted with the arc-shaped surface of the guide rail, thereby buffering the impact force and absorbing part of the vibration force, which is beneficial to protecting the fitting lifting seat and the frame as well as the vibration-absorbing guide wheel assembly itself.

[0018] A further beneficial effect is that the metal ring provided inside the vibration absorbing wheel prevents the vibration absorbing wheel from deforming to improve the buffering and vibration absorbing effect.

[0019] Further beneficial effects are: the oil storage chamber, oil outlet channel, oil outlet groove, rubber plug and lubrication groove provided on the mounting shaft facilitate the oil filling and lubrication of the vibration absorbing guide wheel group. The self-sealing oil filling gap provided on the rubber plug can be directly filled with oil and lubricated without removing the parts, which greatly facilitates the injection of lubricating oil into the vibration absorbing guide wheel group. The lubricating oil can also be stored in the oil storage chamber, and can automatically discharge oil for lubrication when the vibration absorbing guide wheel group guides the lifting seat to move longitudinally.

[0020] A further beneficial effect is that the two side surfaces of the open locating ring respectively fit with the side surface of the sleeve and the side wall of the locating groove, eliminating the gap between the sleeve and the side wall of the locating groove, preventing dust from entering the sleeve and the mounting shaft, and helping to increase the service life of the vibration-absorbing guide wheel set.
