Abstract
The utility model relates to a doubling step-by-step side direction folding pile driver, which is characterized in that the walking gear is composed of a box-shaped track rail, a step-by-step walking frame and a doubling step-by-step transmission mechanism, wherein, the doubling step-by-step transmission mechanism is composed of gear wheels, a toothed rack transmission pair and a driving oil cylinder; when the travel range of the oil cylinder is L, the step-by-step distance is 3L, and accordingly, the utility model can realize doubling step-by-step walking. Simultaneously, double folding operation tower frame can realize side folding, which enhance passing ability to a barrier in the air in complete machine transportation. Thus, the utility model is an ideal pile driving machine for buildings.
Description
The utility model belongs to the building machinery technical field, is specifically related to a kind of times step-by-step movement side-foldable pile driver that increases.
Traditional pile driver is operation on rail mostly, also has plenty of the operation of sliding on steel pipe.During operation, the workman will move heavy rail and sleeper, lays track and moving track constantly, if need to change the operator to the time, be by required angular movement track, pile driver itself also will go to required angle thereupon, the rail ability that falls again operation.Like this, must reduce efficiency of construction, and the workman to pay arduous, heavy work.In addition, the operation pylon of pile driver all is split mostly, need decompose when transportation and take apart, need re-assembly when transporting to site operation, all want crane to cooperate during dismounting, not only transportation and dismounting expense height, and waste of manpower, material resources influence the efficiency of construction of pile driver.In order to solve the above-mentioned deficiency of pile driver operation pylon, the inventor has developed a kind of twofold operation pylon (patent No. 93228282.2) of pile driver.In when transportation, adopt down and arrive behind the joint pylon, on save the folded form of folding before the pylon, realize whole Transporting, support oneself from putting (hydraulic-driven).But the problem of the trafficability characteristic of complete machine effect of altitude bridge letter and aerial barrage thing when also there is transportation in this folding mode.
The purpose of this utility model is to provide a kind of times step-by-step movement side-foldable pile driver that increases, promptly solved pile driver need be laid track when operation problem, when having solved the complete machine transportation again to the influence of aerial barrier trafficability characteristic.
For finishing the foregoing invention purpose, the utility model is to realize like this; This pile driver comprises implement, running gear, takes back the working platform of commentaries on classics supporting and the management system of this machine.The operation pylon of implement is a twofold operation pylon, is made of upper and lower two joints, and the working platform of pylon and pile driver is fixed in the front portion of working platform with stable support, and setting up by hydraulic jack of pylon finished.Running gear is by case-shaped bearing rail, stepping walker and increase a times stepping transmission mechanism and form.One group of rolling road wheel is respectively arranged at the bottom of the both sides girder of stepping walker, this road wheel is positioned at the spill boots groove of case-shaped bearing rail, be that the stepping walker is seated on two case-shaped bearing rails by its road wheel, drive the stepping walker along back and forth walking of case-shaped bearing rail realization by increasing times stepping transmission mechanism.Characteristics of the present utility model are that the described times stepping transmission mechanism that increases is made of rack-and-pinion transmission and driving oil cylinder.Tooth bar divides upper rack and following tooth bar, upper rack to be positioned on the longitudinal centre line below the stepping walker, and it is 2L with length.Following tooth bar is symmetrically distributed in the both sides of the longitudinal centre line above the case-shaped bearing rail, and its length is L.The length that is upper rack is 2 times of following tooth bar length.Be provided with the in-line gears group between upper and lower tooth bar, promptly on an axle, the gear wheel with the upper rack engagement is equipped with in the centre, and the pinion with following tooth bar engagement all is equipped with on both sides, has formed the transmission that wheel and rack is meshed.Driving oil cylinder is fixed in an end of case-shaped bearing rail longitudinal center line position, and the earrings of its oil cylinder piston bar is installed on gear train coaxial, with driven wheel, the motion of tooth bar transmission.Running gear of the present utility model adopts this kind structure, can realize increasing a times step-by-step movement walking.
Realize side direction for the twofold operation pylon that makes this pile driver and unfold that its operation pylon and erecting device are to improve development on the patent No. is the basis of 93228282.2 (the twofold operation pylons of pile driver).This operation pylon comprises the fixing stable support of upper and lower joint pylon and pylon and working platform, joint sets up oil cylinder and goes up joint and set up oil cylinder down.For satisfying the side-foldable condition of pylon, the setting up with the folded joint of going up of 1 lateral arrangement that adopts of side direction of joint pylon of going up that is characterized in this pile driver set up hydraulic oil cylinder driving and set up connecting rod and realize, promptly go up the side that the fulcrum that saves the cylinder body end of setting up oil cylinder is fixed on down the joint pylon, its set up oil cylinder tailpiece of the piston rod fulcrum by lateral arrangement save down pylon top and on joint pylon bottom set up rod hinge connection, by driving the piston motion that it sets up oil cylinder, just can realize setting up or folding of upper and lower two joint pylons like this.But during folded state, because of all there is the cat ladder obstacle pylon both sides, so connect the distance H 〉=2h of two pin-and-hole portions of the connection movable joint plate that upper and lower joint pylon uses, h be last (descending) joint pylon with the bearing pin of movable joint plate connection to the distance between the pylon cat ladder.When satisfying H 〉=2h, the operation pylon just can be avoided the cat ladder obstacle when side-foldable, makes joint pylon is parallel to close up.
