[0022] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those in routine experiments.

[0023] Example: See Figure 1 — Figure 3 :

[0024] A composite bearing oblique pile driver comprises a chassis 1, a pipe-type traveling system 2, hydraulic legs 3, a rammer mechanism, a power control cabinet 15 and a hydraulic control cabinet 14.

[0025] See also Figure 1 — Figure 3 The pipe-type walking system 2 is arranged under the chassis 1, and the hydraulic support legs 3 are arranged at the four corners of the chassis 1. The hydraulic support legs 3 are controlled by the hydraulic control cabinet 14.

[0026] See also Figure 1 — Figure 3 The rammer mechanism includes a telescopic guide slot 7, a lifting pulley block 18, a lifting hoist 9, a column hammer 8, and a rammer hoist 12. An empty slot is provided on the chassis 1 to accommodate the telescopic guide slot 7. One end of the telescopic guide slot 7 is hinged to the chassis 1 via a rotating shaft 27, and the other end is connected to a lifting rope 17 on the lifting hoist 9 on the chassis 1 via a lifting pulley block 18, so that the telescopic guide slot 7 has a raised storage state and a lowered working state; the column hammer 8 is slidably arranged in the telescopic guide slot 7 and is connected to a rammer rope 19 wound on the rammer hoist 12.

[0027] See also Figure 1 — Figure 3 The telescopic guide groove 7 includes a first arc chute and a second arc chute. The top of the first arc chute is connected to the rotating shaft 27, and the second arc chute is slidably connected relative to the first arc chute. The second arc chute is driven by a hydraulic cylinder to extend or retract from the bottom end of the first arc chute.

[0028] A plurality of sliders are respectively provided on the inner side surfaces of the first arc chute and the second arc chute, and the sliders can be rollers.

[0029] See also Figure 1 — Figure 3 A gantry 6 is provided on the chassis 1 at the end corresponding to the connection between the column hammer 8 and the rammer steel rope 19, and a rammer transmission pulley group 25 is provided on the gantry 6. The rammer steel rope 19 passes through the rammer transmission pulley group 25 and is connected to the end of the column hammer 8.

[0030] See also Figure 1 — Figure 3 The chassis 1 is equipped with a lifting support frame 11 corresponding to the lifting pulley group 18. The lifting steel rope 17 of the lifting winch 9 passes through the lifting pulley group 18 on the lifting support frame 11, driving the telescopic guide groove 7 to switch between the lifting and storage state and the downward working state.

[0031] See also Figure 1 — Figure 3 The rammer hoist 12 is driven by a main motor 13, and a hoist brake handle 16 is provided on the rammer hoist 12. A sensor for detecting the pay-off length of the rammer hoist 12 is correspondingly provided on the rammer hoist 12 or its main motor 13.

[0032] In addition, a measuring system is provided in the power control cabinet 15. The measuring system is connected to the sensor to collect information sent back by the sensor and calculate the displacement of the rammer each time it descends. The displacement is displayed or stored.

[0033] An electromagnetic ejection device 20 is installed on the telescopic guide slot 7. This electromagnetic ejection device 20 is located at the connection end between the column hammer 8 and the rammer steel cable 19 and acts on the column hammer 8. When the rammer's descent measured by the measurement system does not meet the standard (i.e., the ramming force is insufficient), the power control cabinet 15 controls the electromagnetic ejection device 20 to apply additional downward force to the rammer, thereby increasing the ramming force.

[0034] Preferably, the rotating shaft 27 is set on a lifting seat, which is guided and slidably connected to the chassis in the up and down directions (preferably, the lifting seat is guided and connected to the vertical column of the gantry 6), and a lifting drive device is set below the lifting seat. The lifting drive device can be a cylinder or a hydraulic cylinder to drive and adjust the height position of the rotating shaft 27 (that is, the end of the telescopic guide groove 7), and then cooperate with the lifting height of the lifting winch 9 to adjust the inclination angle and position of the telescopic guide groove 7 in the downward working state, so that the bottom end of the telescopic guide groove 7 can be well docked with the end of the composite carrier (that is, the steel pipe).

[0035] See also Figure 1 — Figure 3The pipe-type traveling system 2 includes a pipe 28, a sliding support 4, a translational steel rope, a translational directional pulley block 5, and a translational drive winch 26. The pipes 28 are two, arranged parallel to each other at both ends of the chassis 1. The sliding support 4 is slidably mounted on the pipe 28, and the sliding support 4 is fixed to the chassis 1. The translational drive winch 26 drives the sliding support 4 via the translational steel rope passing through the translational directional pulley block 5, causing the chassis 1 to slide translationally on the pipe 28. Specifically, fixed pulleys are provided at each end of the pipe 28, and the translational steel rope passes through each fixed pulley.

[0036] The rammer winch 12 , translation drive winch 26 , and lifting winch 9 are all controlled by the power control cabinet 15 .

[0037] The working process of this embodiment is as follows:

[0038] S1. Level the site to the required elevation of the equipment and measure and locate it;

[0039] S2. Move the composite bearing body oblique pile driver to the designed position;

[0040] S3, by lifting the winch 9 to change the angle between the telescopic guide 7 and the horizontal plane, to achieve preliminary alignment of the telescopic guide 7 and the constructed steel pipe;

[0041] S4. Adjust the hydraulic legs 3 and the sliding supports 4 up, down, left, and right to achieve precise alignment of the column hammer 8 in the telescopic guide groove 7 with the constructed oblique steel pipe;

[0042] S5, using the rammer winch 12 to tamp down and lift the column hammer 8 in the telescopic guide groove 7 and the constructed steel pipe;

[0043] S6, column hammer 8 tamps the soil at the bottom of the steel pipe and continuously adds dry hard concrete and other materials into the steel pipe;

[0044] S7, detecting the falling stroke of the column hammer 8. When it is found that the stroke does not meet the requirement, the electromagnetic ejection device 20 is started to work and ram again. After multiple rammings, a dense and high-bearing-capacity composite bearing body is formed at the bottom end of the steel pipe.

[0045] The above examples are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
