In modern marine development activities, the scale and output value of offshore oil extraction, offshore wind power generation, natural gas development, wave energy development, and photovoltaic power generation are increasing. Since it is impossible to reliably anchor equipment in water, people use machinery to pile and anchor the installation of photovoltaic equipment.

[0003] When existing pile drivers are used to drive foundation piles for offshore photovoltaics in offshore and shallow areas where construction vessels cannot reach, they lack stable support from the seabed surface, often causing the pile pipe to drift and tilt, making the entire pile irregular in shape and difficult to meet qualified usage standards.

[0004] Therefore, there is an urgent need for a crawler type pile driver that provides stable supporting force. Summary of the invention

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a crawler type pile driver that provides stable supporting force.

DETAILED DESCRIPTION

[0023] See also Figures 1 to 5 The utility model relates to a crawler pile-driving frame, comprising a main structure frame 1, a driver's cab 2 is installed on the upper surface of the main structure frame 1, the lower surface of the main structure frame 1 is connected to the crawler walking chassis 4 through a six-degree-of-freedom compensation component 3, and a plurality of pile-holding components 13 are installed on the front of the main structure frame 1, so that when the wind power pile is driven, the pile-holding component 13 at the front end plays a role in holding the pile pipe; the pile-holding component 13 comprises a sliding frame 5 and a sliding cylinder 6 for driving the sliding frame 5 to move forward and backward, so that the sliding frame 5 can move forward and backward to adjust its position under the action of the sliding cylinder 6, and the left and right sides of the front of the sliding frame 5 are rotatably connected with a first pile-holding arm 7 and a second pile-holding arm 8 through a pin shaft, and the first holding arm 7 is connected to the second pile-holding arm 8 through a pin shaft. An arm holding arm rotary cylinder 9 is installed between the pile arm 7 and the second pile holding arm 8 and the sliding frame 5. Conventional pile pipes are fixed cylinders. The opening degree of the first pile holding arm 7 and the second pile holding arm 8 of the hoop structure can be adjusted by the arm holding arm rotary cylinder 9, which is convenient for matching pile pipes of different diameters. The first pile holding arm 7 and the second pile holding arm 8 are both installed with a first pile holding cylinder 10, and the second pile holding cylinder 11 is installed on the front of the sliding frame 5. Rollers 12 are installed at the output ends of the first pile holding cylinder 10 and the second pile holding cylinder 11, so that the first pile holding cylinder 10 and the second pile holding cylinder 11 can be adjusted forward and backward so that the rollers 12 fit on the outer wall of the pile pipe, which is convenient for guiding the pile pipe.

[0024] Furthermore, the main structure frame 1 is formed by a plurality of main support rods 14 and auxiliary support rods 15 that are fixedly connected. The cross-section of the front and rear main support rods 14 is an H-shaped structure. The sliding frame 5 is slidably connected between the two main support rods 14. One end of the sliding oil cylinder 6 is fixedly connected to the rear main support rod 14, and the other end of the sliding oil cylinder 6 is fixedly connected to the sliding frame 5. Such arrangement of the main support rods 14 and the auxiliary support rods 15 can improve the overall strength of the main structure frame 1 and is light in weight. At the same time, the main support rods 14 with an H-shaped cross-section facilitate the sliding of the sliding frame 5, so that the sliding frame 5 is moved forward and backward through the sliding oil cylinder 6 to support the pile pipe.

[0025] Furthermore, the crawler-type walking chassis 4 includes a fixed chassis 17 and walking crawlers 18 installed on the front and rear sides of the fixed chassis 17, and the six-degree-of-freedom compensation assembly 3 includes six compensation cylinders 16, one end of the compensation cylinder 16 is rotatably connected to the fixed chassis 17, and the other end of the compensation cylinder 16 is rotatably connected to the main support rod 14. In this arrangement, regardless of whether the ground is flat or not, the main structure frame 1 can be always in a horizontal state by controlling the six compensation cylinders 16, so that the pile is driven more vertically when the pile pipe is supported by the pile holding assembly 13, thereby improving the pile driving quality of the pile pipe.

[0026] Furthermore, the number of the pile holding components 13 is three groups, and the number of each group of pile holding components 13 is two. In this way, the upper and lower sides of the pile pipe are supported by two pile holding components 13 to avoid tilting, and the pile driving is more stable; because offshore photovoltaics are all in pieces, there are many foundation piles, and the distance between two piles is also required to have a certain accuracy. Since the number of pile holding components 13 is three groups, three piles can be driven in one positioning, which not only improves efficiency, but also ensures the distance between piles. After driving these three piles, the crawler-type walking chassis 4 can quickly move to the next position to continue construction.

[0027] Further, the sliding frame 5 includes a front cross bar 19 and a rear cross bar 20, which are fixedly connected by two connecting rods 21, and the rear cross bar 20 and the connecting rod 21 are slidably connected inside the main support rod 14, and the front cross bar 19 is longer than the rear cross bar 20. In this arrangement, the rear cross bar 20 and the connecting rod 21 can be driven to slide inside the main support rod 14 by the sliding cylinder 6, and the sliding is more stable.

[0028] Furthermore, there is one first pile holding cylinder 10 on the first pile holding arm 7 and it is installed in the middle of the first pile holding arm 7, and there are two first pile holding cylinders 10 on the second pile holding arm 8 and they are installed in the front side and the middle of the second pile holding arm 8. This arrangement enables the rollers 12 on the first pile holding cylinder 10 and the second pile holding cylinder 11 to hold the pile pipe tightly on all four sides, making it more stable when supporting.

[0029] Furthermore, the plurality of rollers 12 are used to contact the surface of the pile pipe and can rotate along the surface of the pile pipe. This arrangement reduces the friction between the pile pipe and the rollers 12, and the rollers 12 can rotate along the surface of the pile pipe when supporting the pile pipe, which has a better guiding effect on the pile pipe and can better pile the pile pipe.

[0030] The working principle of a crawler pile driver of the utility model is as follows: when in use, the first pile holding arm 7 and the second pile holding arm 8 are opened by the arm rotating oil cylinder 9, and then the pile driver is moved to the position where pile driving is required by the crawler walking chassis 4, and then the six-degree-of-freedom compensation component 3 is controlled to make the main structure frame 1 in a horizontal state, and then the sliding frame 5 is driven to move back and forth by the sliding oil cylinder 6, so that the pile pipe is located between the first pile holding arm 7 and the second pile holding arm 8, and then the arm rotating oil cylinder 9 is started to extend to close the first pile holding arm 7 and the second pile holding arm 8, and the pile pipe is surrounded by the first pile holding arm 7 and the second pile holding arm 8, and then the first pile holding oil cylinder 10 and the second pile holding oil cylinder 11 are started to extend, driving the roller 12 to contact the outer surface of the pile pipe to guide the pile pipe, thereby playing a role in holding the pile pipe, avoiding the pile pipe from drifting and tilting, making the molding of the entire pile more standardized and reaching the qualified use standard.

[0031] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
