Technical Field

[0001] The present invention relates to the technical field of engineering machinery, in particular to a multifunctional spiral drilling pile testing machine. Background Art

[0002] At present, most existing spiral pile drilling machines usually only have the function of drilling pile holes, and some spiral pile drilling machines are integrated with pile driving devices, which can realize drilling and pile driving in one.

[0003] However, after driving the pile, it's often necessary to test the maximum bearing capacity of the pile. Currently, this is typically done by applying pressure to the pile. This involves removing the driving device after driving, then applying a certain amount of pressure to the pile to determine whether the pile moves within a certain timeframe under the set maximum bearing capacity. This method requires specialized testing equipment, has a limited function, and cannot be used with existing auger pile drivers. Furthermore, the testing costs are relatively high. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a multifunctional spiral drilling pile testing machine.

[0005] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0024] To facilitate understanding of the present invention, the present invention will be described in more comprehensive and detailed form below in conjunction with the accompanying drawings and preferred embodiments. However, the protection scope of the present invention is not limited to the following specific embodiments.

[0025] like Figure 1-5 As shown, this embodiment discloses a multifunctional auger pile testing machine, including a body platform 1, a traveling mechanism 2, an auger drilling mechanism 3 and a counterweight 4. The traveling mechanism 2 is mounted on the lower side of the body platform 1, and the counterweight 4 is stacked on the upper side of the body platform 1. The auger drilling mechanism 3 is detachably mounted on the body platform 1. A pile testing column 5 for pressing on an engineering pile (the engineering pile includes a prefabricated pile prefabricated in a factory, a prefabricated pile pressed in on site, and a cast-in-place pile directly cast on site) is mounted on the lower side of the body platform 1. Thus, the body platform 1 can accommodate the installation of the auger drilling mechanism 3 and the counterweight 4. When the auger drilling mechanism 3 is mounted on the body platform 1, pile holes can be drilled. After the pile is pressed, the auger drilling mechanism 3 is disassembled, the body platform 1 is moved to the position of the engineering pile, the pile testing column 5 is pressed on the engineering pile, and the counterweight is gradually added to the body platform 1. Then, the maximum bearing capacity of the engineering pile is detected to achieve the purpose. The main structures such as the body platform 1 and the traveling mechanism 2 can be shared, thereby greatly saving costs.

[0026] In this embodiment, a fuselage plane 11 for stacking counterweights 4 is provided on the upper side of the fuselage platform 1. The plane structure can be better used for stacking counterweights. A platform hole 12 for the spiral drill 31 of the spiral drilling mechanism 3 to pass through is provided on the fuselage plane 11. The platform hole 12 deviates from the center of gravity position of the platform hole 12 and is used for the spiral drill 31 to penetrate the fuselage plane 11 to drill pile holes.

[0027] In this embodiment, a slide groove 13 is provided on the underside of the fuselage platform 1, with the upper end of the pile column 5 slidingly engaged with the slide groove 13. Specifically, the slide groove 13 is a T-shaped slide groove, and one end of the pile column 5 is provided with a T-shaped sliding end 51. This facilitates quick removal and installation of the pile column 5 and also facilitates adjustment of the pile column 5 to align with the precast pile.

[0028] In this embodiment, the walking mechanism 2 includes a hydraulic lifting leg 21 and a support boat 22. The support boat 22 includes long boats 222 on both sides of the transverse direction and short boats 223 on both sides of the longitudinal direction. The long boat 222 and the short boat 223 are both provided with a slide rail 221. The upper end of the hydraulic lifting leg 21 is connected to the fuselage platform 1, and the lower end is slidably connected to the slide rail 221 on the support boat 22. Specifically, a lifting leg driving cylinder 23 for driving the hydraulic lifting leg 21 to slide is installed on the support boat 22. The piston rod of the lifting leg driving cylinder 23 is hinged to the hydraulic lifting leg 21, so that Figure 4 The fuselage platform 1 can move left and right relative to the long ship 222 and longitudinally relative to the short ship 223, thereby accurately aligning the pile column 5 with the precast pile.

[0029] In this embodiment, in order to simultaneously monitor the working conditions on the upper and lower sides of the fuselage platform 1, ensuring rapid and safe construction, an operator's cab 6 is also included. The operator's cab 6 is mounted on one side of the fuselage platform 1 so that it can be raised and lowered. Specifically, a support platform 15 is provided extending outward from one side of the fuselage platform 1. An operator's cab lifting cylinder 16 is vertically mounted on the fuselage platform 1. The operator's cab lifting cylinder 16 can be connected in parallel with the hydraulic system of the fuselage platform 1. The piston rod of the operator's cab lifting cylinder 16 is mounted to an operator's cab mounting platform 17, and the operator's cab 6 is mounted on the operator's cab mounting platform 17.

[0030] In this embodiment, a flip bracket 18 is installed on one side of the fuselage platform 1. The flip bracket 18 is cantilevered relative to the fuselage platform 1 and does not occupy the space for stacking counterweights. A generator set 7 for powering the spiral drilling mechanism 3 and the operating room 6 is installed above the flip bracket 18, that is, the generator set 7 is a common power supply center. The generator set 7 can be easily disassembled and will not interfere with the stacking measurement of the counterweight 4.
