Description

Technical Field

[0001] The invention relates to the field of building strain force testing equipment, in particular to a guide frame for high-strain pile testing. Background Art

[0002] The high strain hammer system is a hammer system used in the high strain method detection of pile foundations, which includes a heavy hammer, a support guide frame, a decoupling device, a hanging system, a penetration test system, etc. The support guide frame mainly undertakes two functions: guidance and support. First, it can support the weight of the heavy hammer and bear all the weight of the heavy hammer transferred from the crane to the support guide frame; second, during the falling process of the hammer body, it must ensure that the hammer body hits the pile core during the vertical fall (free fall) of the hammer body, and plays a guiding role in the hammering process. Usually, the weight of the heavy hammer is between 30 tons and 100 tons. In order to better support the weight of the heavy hammer, the support guide frame generally adopts a fixed steel frame structure with a height of 2 meters to 4 meters. Although it can well guarantee the support performance of the support guide frame, due to its tall rigid structure, the support guide frame is not easy to carry and transfer. After the high strain pile measurement is completed, the storage of the support guide frame is also inconvenient and requires a large storage space.

[0003] The high strain pile test method hammering system disclosed in the Chinese patent application No. 201220318940.1 includes from top to bottom: a lock plate type unhooking device, a heavy hammer and a telescopic guide frame. The telescopic guide frame is a three-dimensional frame body, which is composed of a base section and an adjustment section. The longitudinal section of the base section is a trapezoid. The base section is provided with a top surface and a bottom surface. The two sides of the bevel are divided into a lower section, a middle section and an upper section from bottom to top. The longitudinal section of the adjustment section is two rectangles, which forms a new high strain pile test method hammering system. Although the guide frame can be retracted to a certain extent by adjusting the section to reduce the space occupancy of the guide frame, the design of the telescopic structure will reduce the support performance of the guide frame to a certain extent, and the height of the guide frame after retraction is still very high, and the difficulty of storage and transportation is still very large. Summary of the invention

[0004] To solve the above problems, the present invention provides a guide frame for high-strain pile measurement, which has a simple structure and is easy to use. The height of the guide frame can be lowered by flipping, thereby solving the problem of inconvenient storage and transfer of the guide frame.

[0027] In more detail, the flipping guide frame 4 is an L-shaped structure, and the fixed support frame 2 cooperates with the flipping guide frame 4 to form a frame structure with a quadrilateral cross-section. The top of the flipping guide frame 4 is provided with a load-bearing fixed beam 42 for connecting a decoupling device, and the decoupling device is used to connect a heavy hammer, and the heavy hammer can be suspended between the fixed support frame 2 and the flipping guide frame 4 through the decoupling device.

[0028] The flip guide frame 4 is provided with a connecting sub-seat 41, and at least one connecting sub-seat 41 is provided, which is arranged at the connection between the flip guide frame 4 and the fixed support frame 2. The fixed support frame 2 is provided with a connecting female seat 21 that cooperates with the connecting sub-seat 41, and the connecting sub-seat 41 and the connecting female seat 21 are locked by a locking shaft 5. In more detail, in the present embodiment, there are two connecting sub-seats 41, which are symmetrically arranged on the front side of the flip guide frame 4. Correspondingly, the fixed support frame 2 is provided with two connecting female seats 21 adapted to the connecting sub-seat 41. When the flip guide frame 4 is flipped and carried on the fixed support frame 2, the connecting sub-seat 41 cooperates with the connecting female seat 21. One end of the locking shaft 5 is connected to a hydraulic cylinder 52 through a connecting head 51. The hydraulic cylinder 52 is installed on one side of the connecting female seat 21 through a fixed seat. The extension of the push rod of the hydraulic cylinder 52 can push the locking shaft 5 to insert into the connecting hole between the connecting sub-seat 41 and the connecting female seat 21, so as to lock the connecting sub-seat 41 and the connecting female seat 21. The locking shaft 5 and the connecting head 51 are hinged or welded through a rotating shaft.

The flip hydraulic cylinder 6 can rotate relative to the basic base 1. When the flip guide frame 4 flips toward the basic base 1, the flip hydraulic cylinder 6 can flip synchronously with the flip guide frame 4. During the flipping process, the push rod of the flip hydraulic cylinder 6 contracts; when the flip guide frame 4 flips toward the fixed support frame 2, the flip hydraulic cylinder 6 can flip synchronously with the flip guide frame 4. During the flipping process, the push rod of the flip hydraulic cylinder 6 extends to apply thrust from both sides of the flip guide frame 4, which is conducive to the smooth flipping of the flip guide frame 4.

[0031] The bottom of the fixed support frame 2 is connected to the basic base 1 via a connecting foot 22, and the fixed support frame 2 and the connecting foot 22 are detachably connected via bolts, and the connecting foot 22 is welded to the basic base 1. In addition, the mounting seat 3 is also connected to the basic base 1 via the connecting foot 22, and the height of the fixed support frame 2 and the flip guide frame 4 can be adjusted by adding a gasket between the mounting seat 3 and the connecting foot 22 and between the fixed support frame 2 and the connecting foot 22.

[0032] In more detail, in order to improve the load-bearing performance and structural stability of the fixed support frame 2 and the flip guide frame 4, the fixed support frame 2 includes three parallel lower left longitudinal beams 23 and three parallel lower right longitudinal beams 24, wherein no less than 5 parallel cross beams 25 are connected between two of the left lower longitudinal beams 23 and between two of the parallel lower right longitudinal beams 24, and cross beams 25 and oblique beams 26 are connected between the remaining two of the left lower longitudinal beams 23 and between two of the parallel lower right longitudinal beams 24, and the cross beams 25 and oblique beams 26 are arranged at intervals.

The top of the top frame is provided with a left top cross beam and a right top cross beam, and the load-bearing fixed cross beam 42 is carried on the left top cross beam and the right top cross beam.

[0034] In addition, the flip guide frame 4 includes a connecting cross beam 47 and a connecting longitudinal beam 48. At least three connecting cross beams 47 are provided on both the front and rear sides of the flip guide frame 4, and are connected in parallel between the outermost left upper longitudinal beam 43 and the right upper longitudinal beam 44. The connecting longitudinal beam 48 is connected between two of the connecting cross beams 47.

[0035] The flip guide frame 4 and the fixed support frame 2 are both constructed of steel sections, with high structural stability and not easy to deform, so that the high-strain pile measuring guide frame can have a bearing capacity of up to 350 tons and good supporting capacity, which can meet the lifting needs of heavy hammers of different tonnages.

[0036] The invention discloses a guide frame for high-strain pile measurement with simple structure, and has both structural stability and flexibility. During testing, the flip guide frame can be flipped and combined with a fixed support frame. Both the flip guide frame and the fixed support frame are rigid structures, so that the overall structural stability of the high-strain pile measurement guide frame is high, and the supporting capacity is high, which can meet the need of supporting a heavy hammer. When the test is completed, the flip guide frame can be flipped so that the flip guide frame is separated from the fixed support frame and parallel to the foundation base, thereby reducing the overall height of the high-strain pile measurement guide frame, which is beneficial to the transportation, transfer and storage of the high-strain pile measurement guide frame.
