Description

Double-holding-pressure power underneath pile driver

Technical Field

The invention belongs to the technical field of buildings, relates to a pile driver, and particularly relates to a double-holding-pressure power lower pile driver.

Background

At present, there are two types of piling machines used on construction sites: the structure of the pile driver is pile driving equipment which utilizes a drill rod suspension bracket pulled up by a winch to drive a drill rod drill bit to form a hole on an underground drilling machine through a power head; the other type is an impact hammer pile driver, and the structure of the pile driver is that a winch is used for pulling the impact hammer to fall repeatedly and lift the impact hammer to realize pile driving. Wherein, the rotary pile driver mainly realizes the purpose to the underground drill rod through the circumferential direction of drilling rod when the pile is driven, adopt the grout to cool down and carry out the grout operation to the drilling rod when drilling rod drilling, common grout mainly carries out the whitewashing through the grout hole of drilling rod tip, when the drilling rod bores certain degree of depth, need add the festival to the drilling rod, make the drilling rod extension, just can continue to bore down, when the grout operation, the adoption is usually docking drilling rod and extension bar, make grouting channel intercommunication, realize the grout.

In the process of drilling a drill rod downwards or lengthening the drill rod, because the stroke of the pile driver is limited, the existing holding type pile driver needs to firstly loosen the drill rod, then the holding device moves upwards, and then holds the drill rod tightly after the holding device is in place, in the process, the drill rod loses the supporting force and the downward power, if the drill rod continuously rotates, the drill rod tends to incline, so that the drilling hole is not vertical, or when the drill rod is used for guniting, a vertical cement mixing pile cannot be obtained, therefore, the drilling operation needs to be stopped when the holding device loosens the drill rod, even if the drilling hole is stopped, the drill rod does not obtain the support of the force in the horizontal direction, the drill rod still can incline to a certain degree, the perpendicularity of the drilling hole or the pile body produced in the guniting process of the drilling operation is inclined, and the engineering quality.

Chinese patent document discloses a grouted pile screw lifting mud drill rod [ application number: 201410263015.7], which comprises one or more sections of hollow drill rods and drill rod joints connected with the hollow drill rods, wherein helical blades are arranged on the outer surfaces of the hollow drill rods, each section of hollow drill rod is connected with each other through the drill rod joints, and a grout spraying port is arranged at the connection part of the first section of hollow drill rod and the drill bit. Typically, the helical blade is welded to the core hole and is arranged in the lower section of the core drill rod, the length of the helical blade being 1/4-1/2 of the total length of the core drill rod, the diameter of which is smaller than the diameter of the drill bit. During construction, the helical blade rotates along with the positive direction of the drill rod, and generates upward lifting force for mud at the lower section of a pile hole, mud blocks in the mud and the like and downward propelling force for the drill rod. This scheme utilizes hollow drilling rod to carry out the thick liquids and carries, when hollow drilling rod has the multisection, need connect between the drilling rod, but the length of flexible drilling rod is limited after all, and its principle is obviously different with the formula drilling rod of embracing pressure.

The driving mechanism of the existing drill rod is positioned at the top, the hollow drill rod is used for conveying slurry, when the hollow drill rod has a plurality of sections, the length of the drill rod is lengthened, the power for driving the drill rod cannot guarantee the verticality of the drill rod with longer length, and the driving force required to be provided for the drill rod is larger and the energy consumption is larger due to the synchronous rotation of the drill rods and the drill bits.

For the above reasons, people have been continuously exploring to develop a power underneath type drilling machine, for example, a power underneath type telescopic mixing pile machine is disclosed in chinese patent document [ application number: 201201693119. X ], including a pile frame, the sliding platform who reciprocates along pile frame, the setting is on the chassis of pile frame lower part, install the water swivel above the sliding platform and be located the square flexible drilling rod that sliding platform below and water swivel are connected, install straight-tooth reducing gear box and motor on the chassis, the shaft hole of the driving gear of straight-tooth reducing gear box is the round hole, driven gear's shaft hole is the square hole, the motor shaft inserts in the round hole, it is rotatory to drive the driving gear, insert square flexible drilling rod in the square hole, the square hole becomes clearance fit with the outmost drilling rod of square flexible drilling rod, make square flexible drilling rod can reciprocate along the square hole and can rotate along with driven gear rotates. The whole pile machine gravity center of the scheme moves downwards, the whole weight of the pile machine frame and the chassis is light, the cost is reduced, the structure is simple, and the pile machine is more stable and safer and is convenient to maintain. However, this scheme telescopic drill rod rotates with the gear is synchronous, and when telescopic drill rod was wrapped up in by earth or clay, the resistance grow, and the power that needs also can last the grow.

To sum up, when the drilling rod needs to be driven into the ground below a certain depth, the pressure holding type working process is used, the defect of intermittent operation can be caused, the continuity of the drilling work is influenced, in addition, the verticality of the drilling rod cannot be guaranteed, the engineering quality is influenced, the drilling rod and the drill bit of the existing pile driver arranged under the power rotate together, the resistance can be larger and larger, and the drilling efficiency can be lower and lower.

It will be appreciated by those skilled in the art that the pile driver is prior art and employs oil pressure to drive the pile. Therefore, the clasping and pressing mechanism belongs to the prior art and is not described in detail herein. When the secondary holding and pressing mechanism 8 holds the extension bar mechanism 6, the axis lines of the primary holding and pressing mechanism 7 and the secondary holding and pressing mechanism 8 are superposed and are positioned on the same straight line. As is well known, the stroke that one-level enclasping mechanism 7 moved along vertical direction is limited, when 7 enclasping extension bar mechanisms of one-level enclasping mechanism moved to the lower limit, can't continue to drive the drilling rod and down moved, at this moment one-level enclasping mechanism 7 loosens extension bar mechanism 6 earlier and moves to the upper limit along vertical direction, enclasping extension bar mechanism 6 again, so reciprocal, lasted extension bar mechanism 6 down the drive down.

In the process of clasping and loosening the drill rod 100 by the one-stage clasping and pressing mechanism 7, the drill rod system 2 is also needed to stop the drilling operation due to the fact that the lengthening rod mechanism 6 loses the supporting force, the drill rod system 2 is required to stop the drilling operation, the drill rod is inclined on the other hand, the verticality of the drill rod cannot be guaranteed, the further verticality of the drill hole cannot be guaranteed, and if the drill hole is used for manufacturing a cement soil mixing pile or a drilling pile, the quality of the cement soil mixing pile or the drilling pile is reduced.
