Fig. 1 is a kind of portable hydraulic base expanding and base expanding device structural schematic diagram for base expanding and base expanding pile foundation construction of the present invention;
Fig. 2 is partial enlargement diagram in Fig. 1;
Fig. 3 is the hydraulic principle figure of embodiment.
In figure: 1, support rod, 2, positioning chuck, 3, postive stop baffle, 4, work capsule, 5, oil return pipe, 6, oil inlet pipe, 7, connect Head, 8, fuel reserve tank, 9, motor, 10, hydraulic pump, 12, overflow valve, 13, pressure gauge, 14, reversal valve, 18, sealing joint strip, 19, Fixed plate, 20, limit card body.
Specific embodiment
Below with drawings and examples, the invention will be further described.
Referring to Figures 1 and 2, in Fig. 1 and Fig. 2, work capsule 4 is in the signal state of two extreme positions.It is of the invention a kind of Portable hydraulic base expanding and base expanding device for base expanding and base expanding pile foundation construction, comprising: support rod 1, positioning chuck 2, oil inlet pipe 6, oil return pipe 5, work capsule 4, fixed plate 19, sealing joint strip 18, postive stop baffle 3 and limit card body 20.The lower end of support rod 1 is fixed with positioning card First 2, be fixed with oil inlet pipe 6 and oil return pipe 5 in positioning chuck 2, work capsule 4 be set in the bottom of positioning chuck 2, work capsule 4 with Sealing joint strip 18 is equipped between fixed plate 19, positioning chuck 2, work capsule 4, sealing joint strip 18, fixed plate 19 are sequentially connected, oil inlet Pipe 6 and oil return pipe 5 are connected to work capsule 4, are hinged with postive stop baffle in the bottom in the outside, positioning chuck 2 that are located at work capsule 4 3, card body 20 is limited in the outside of postive stop baffle 3, the bottom setting of positioning chuck 2.The every 3m of support rod 1 is segmented for one, and two points It is connected between section by connector 7.In base expanding and base expanding construction operation, support rod 1 and positioning chuck 2 can play fixed function, thus Realize the stability of work progress.Work capsule 4 squeezes weak soil body by expansion to realize base expanding and base expanding operation.Capsule 4 work using existing There is material production, can be composite rubber-plastic material, be also possible to leather liner rubber composite material, the height of rubber can also be utilized Molecular characterization vulcanizes with high strength fibre cloth.Requirement to work capsule 4: expansion, shrinkage are good, and abrasion resistance properties are excellent It is good, it is reusable.
Referring to Fig. 3, a kind of portable hydraulic base expanding and base expanding device for base expanding and base expanding pile foundation construction of the invention uses existing skill The hydraulic control system of art, hydraulic control system are technologies familiar to those skilled in the art.The hydraulic control of the present embodiment System is simple principle signal, it provides pressure, inlet port and the fuel reserve tank 8 of hydraulic pump 10 by motor 9 and hydraulic pump 10 In oil, the press oil port of hydraulic pump 10 is connect with reversal valve 14, the hydraulic control hydraulic fluid port of overflow valve 2, pressure gauge 13 respectively by pipeline, is changed It is connected to the oil outlet all the way of valve 14 with the oil inlet pipe 6 of work capsule 4, the another way oil return opening of reversal valve 14 and returning for work capsule 4 The another way oil return opening of oil pipe 5, reversal valve 14 is connected to fuel reserve tank 8, and the oil return opening of overflow valve 2 is connected to fuel reserve tank 8.Hydraulic control The operating pressure of system processed is set by overflow valve 2, is shown by pressure gauge 13.
When base expanding and base expanding construction operation: after machine drill hole hole to be drilled is completed, by the portable of base expanding and base expanding pile foundation construction of the invention Hydraulic base expanding and base expanding device is put into drilling, starting motor 9 drive hydraulic pump 10 work, reversal valve 14 commutate, hydraulic oil by into Oil pipe 6 is pressed into work capsule 4, and the work expansion of capsule 4 carries out base expanding and base expanding operation to weak soil body;Due in the outside for being located at work capsule 4, determining Position clamp 2 bottom be hinged with postive stop baffle 3, postive stop baffle 3 under the action of working 4 expansive force of capsule, using hinge joint as axis and A set angle is rotated, due also to limiting card body 20, limiting block in the outside of postive stop baffle 3, the bottom setting of positioning chuck 2 Plate 3 is limited by the restraining force for limiting card body 20;When base expanding and base expanding construction stops, reversal valve 14 commutates, the hydraulic oil to work in capsule 4 It is returned in fuel reserve tank 8 by oil return pipe 5.
The above not does limitation in any form to the present invention, according to the technical essence of the invention to Any simple modification, equivalent change and modification made by upper embodiment, still fall within the scope of technical solution of the present invention.
