Specific embodiment
The specific embodiment for playing the load test device of hanging piece to in-pile component of the present invention with reference to the accompanying drawing is made in detail
Explanation.
The hanging piece that rises of in-pile component includes that lifting screws in bar and lifting screws in part, and the two is in top or lower part in-pile component
It is clamped when lifting, and top or lower part in-pile component is carried out by promotion movement by suspender.
Referring to attached drawing 1, load test device includes pedestal 1, bolt tensioning jack 2 and cushion cover 3, is provided with screw hole on pedestal 1, is used
It is lifted by crane in installation and screws in part 5, cushion cover 3 is arranged above bolt tensioning jack 2, and lifting screws in bar 4 and passes through cushion cover 3 and bolt tensioning jack
2, which screw in part 5 with lifting fixed on pedestal 1, cooperates, and the lifting after 2 pairs of bolt tensioning jack cooperations screws in bar 4 and lifting screws in part 5
It generates and continues pulling force realization load test.
Bolt tensioning jack 2 includes the bridge formation 6 of lower section, the hydraulic cylinder 7 for 6 tops of building bridge and the thread with the cooperation of hydraulic cylinder 7
Cap 8, bridge formation 6 are mounted on pedestal 1, and cushion cover 3 is mounted on thread cap 8, and when hydraulic cylinder 7 pressurizes, thread cap 8 generates upward power
Bar 4 is screwed in lifting to be pulled up.
Referring to attached drawing 2,3, it is that rotary clamping mode connects that lifting, which screws in bar 4 and screws in part 5 with lifting, and lifting screws in 4, bar
Pin hole 9 is arranged in portion, and keyway is arranged in the outer circle that lifting screws in part 5, and setting locking indicator 12, is latched indicator 12 on pedestal 1
Including main shaft 13, upper end bolt 14 is arranged in the top of main shaft 13, and the lower end of main shaft 13 is keyed spindle nose, and the lower section of main shaft 13 is arranged
Bolt 15 is arranged in semi-disc 10, semi-disc 10, and main shaft 13 cooperates in dowel hole 11, inserts when lifting screw-in bar 4 turns to upper end
Pin 14 is inserted into pin hole 9, and when lower end bolt 15 and lifting screw in the keyway cooperation of part 5, lifting screws in bar 4 and lifting screw-in part 5
Assembly positioning is completed.
Referring to attached drawing 4, hydraulic cylinder 7 is connected to pressure pump 18 by oil pipe 16 and connector 17, and pressure is arranged on connecting line
Table 19.Pressure pump 18 is manual pump, and non-return valve 20 is arranged on connecting line, and pressure gauge 19 is located at non-return valve 20 and hydraulic cylinder 7
Between.
The pedestal 1 of experimental rig, is latched the optional stainless steel material of the components such as indicator 12 at cushion cover 3.
