Description

A kind of crawler pile frame

Technical field the utility model relates to a kind of crawler pile frame that hangs and install foundation construction machineries such as pile driver, rig.

The background technology pile frame is a kind of plant equipment commonly used in the construction foundation working, foundation construction machineries such as various pile drivers, rig all need hang and be installed in constructs on the pile frame, crawler pile frame is a kind of in all kinds of pile frames, walks in the crawler belt mode, has the displacement flexible characteristic.

Crawler pile frame mainly is made of the chassis that comprises crawler unit, fuselage, column, bearing diagonal and dynamical system.

The patent No. 00201246.4 and 97233755.5 discloses a kind of electric endless track type pile frame: being characterized in, is power with the industrial power, directly drives crawler unit with motor; The both sides track frame rigidly fixes with chassis crossrail and connects, and the width between the crawler belt of both sides can reach about 6000mm, good stability.But weak point is:

1. be subjected to the job site condition restriction, can't use in the building site that does not have industrial power.

2. can not install and use hydraulic pressure kind equipments such as hydraulic pile driver, hydraulic drill rig, the scope of application has limitation.

3. because the chassis size is big, needing has increased dismounting and assembly working amount with transporting after the crawler unit dismounting, and transportation is inconvenient.

4. bearing diagonal one end fulcrum is at waist, and the below is unsettled, and far away with the rear support leg distance, and column can shake during operation, instability.

Number of patent application 200410070744.7 discloses a kind of electric hydraulic crawler type pile driver: be characterized in, can select different power drive modes, be not subjected to the job site to have or not the condition restriction of industrial power; Can install and use hydraulic pressure kind equipments such as hydraulic pile driver, hydraulic drill rig; Width between the crawler belt of both sides can be widened more than the 6000mm good stability automatically; Can be contracted to automatically below the 3300mm again, convenient transportation need not dismounting; Bearing diagonal one end places on the side bar of rear support leg, and is more stable; Overcome the part deficiency of above-mentioned electric endless track type pile frame, but still had following shortcoming:

1. because the pile frame overall weight is supported by the both sides crawler unit, when the both sides crawler unit shrinks or widens when mobile, crawler belt and ground can produce bigger frictional resistance, hinder normally mobile.

2. the both sides crawler unit shrink or the process of widening in because relative movement distance is longer between the sliding beam on the crawler belt support and the overhanging crossbeam on the chassis, and be sliding friction, so frictional resistance is big, move dumb.

When 3. the explosive motor of dynamical system and motor are installed on the fuselage simultaneously, the structure more complicated.

4. with reference to Figure 12, Figure 13, though bearing diagonal 91 1 ends place on the side bar 93 of rear support leg 92, stability than the bearing diagonal of above-mentioned electric endless track type pile frame increases, but, also can cause the column in the operation to rock owing to there is big gap 95 between the side bar 93 of telescopic rear support leg 92 and the rear cross beam 94.

The summary of the invention the purpose of this utility model is to provide a kind of structure and stress reasonable, and walking and job stabilization height are strong to job site condition compliance, transports the crawler pile frame of conveniently moving.

The purpose of this utility model is realized by following technical proposals:

A kind of crawler pile frame mainly comprises: chassis, fuselage, column, bearing diagonal and dynamicliquid pressure system.

It is characterized in that: on the fuselage of pile frame rotor machine can also be set, described main motor can also be connected with rotor machine except can external industrial power, provides power supply by rotor machine.

Described crawler unit also can be installed Motor Drive except installing the fluid motor-driven; Hydraulic motor and motor can also be installed on the crawler unit simultaneously, and drive crawler travel respectively by the switching of clutch.

The base on described chassis is provided with lifting gear, flexible by the lifting hydraulic cylinder of lifting gear, lifting action can be finished in the chassis, in the contraction of both sides crawler unit or widen and move, can alleviate the weight that crawler unit bears, the frictional resistance that reduces ground; The overhanging crossbeam on chassis is provided with guide roller, and when the both sides crawler unit shrank or widens, guide roller was adjusted to the precalculated position, forms rolling friction and rolling guide frame between overhanging crossbeam and the sliding beam, makes action smooth and easy flexibly.

Described rear support leg is made of swing crossbeam and supporting cylinder, and an end fixed support hydraulic cylinder of swing crossbeam, the other end connect with the rear cross beam of fuselage swingably by bearing pin and be fixing; One end of bearing diagonal is hinged on the swing crossbeam of rear support leg.

Crawler pile frame of the present utility model has following good effect and advantage:

1, the main motor of dynamicliquid pressure system can be selected external industrial power flexibly or use the rotor machine power supply, is not subjected to the job site to have or not the condition restriction of industrial power, and compliance is strong, and the scope of application is wide.

2, crawler unit can select hydraulic motor or motor directly to drive according to on-the-spot different condition.

3, owing to be provided with lifting hydraulic cylinder and guide roller on the chassis, stress is reasonable when shrinking and widening, frictional resistance is little, action is smooth and easy flexibly to make the both sides crawler unit.

4, because rear support leg adopts swing type beam structure and bearing pin rigid connection, promptly convenient the transportation increased the stability of bearing diagonal and pile frame integral body again.

5, because the swing crossbeam of rear support leg can be the position, oblique angle, the column active force is delivered to ground through bearing diagonal, swing crossbeam, rear support leg to be close to equidirectional, and stress is reasonable, and pile frame stability is improved.
