[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0041] Reference Figure 1 The embodiment of the utility model discloses an automatic loading and unloading hoisting frame for a photovoltaic pile driver, which is applied to a photovoltaic pile driver and used for hoisting a pipe pile 1, including a fixed center frame 2, a hoisting beam 3, a first hook 4, a first hook moving device 5, a second hook 6, and a second hook moving device 7.

[0042] The fixed center frame 2 is fixed to the bottom of the hammer head 8 of the photovoltaic pile driver, and the lifting beam 3 is horizontally installed on the fixed center frame 2. The lifting beam 3 includes a first end 301 and a second end 302 opposite to each other in the horizontal direction. The distance from the first end 301 of the lifting beam 3 to the fixed center frame 2 is equal to the distance from the second end 302 of the lifting beam 3 to the fixed center frame 2; one end of the first hook 4 is arranged above the first end 301 of the lifting beam 3, and one end of the first hook 4 moves along the lifting beam 3 under the push of the first hook moving device 5. The beam 3 moves in the transverse direction, and the other end of the first hook 4 is located below the lifting beam 3; one end of the second hook 6 is arranged above the second end 302 of the lifting beam 3, and one end of the second hook 6 moves along the transverse direction of the lifting beam 3 under the push of the second hook moving device 7, and the other end of the second hook 6 is located below the lifting beam 3, the first hook 4 and the second hook 6 are respectively connected to the hammer head 8 through the rope 901, and the other end of the first hook 4 and the other end of the second hook 6 jointly clamp the pipe pile 1. Figure 1 The omitted part above the middle hammer head 8 is the main structure of the photovoltaic pile driver, which is omitted because it is not an innovation of the present utility model.

[0043] In this embodiment, the fixed center frame 2 is the core support structure of the entire automatic loading and unloading hoisting frame. It is welded with high-strength steel to ensure that it can withstand sufficient weight and stress during the hoisting process. The fixed center frame 2 can be firmly installed at the bottom of the hammer head 8 of the photovoltaic pile driver by welding, bolts or other fastening devices to ensure its firm connection with the hammer head 8. The hoisting beam 3 is laterally installed on the fixed center frame 2, and its two ends are respectively a first end 301 and a second end 302. In order to ensure the balance and stability of the hoisting process, the hoisting beam 3 is designed to be symmetrical about the fixed center frame 2. The hoisting beam 3 is also made of high-strength steel to ensure that it will not bend or break when hoisting the pipe pile 1.

[0044] One end of the first hook 4 can be directly placed above the first end 301 of the hoisting beam 3, or a slide rail can be further arranged above the first end 301 of the hoisting beam 3, and a pulley can be arranged at one end of the first hook 4, so as to ensure that it can move in the transverse direction of the hoisting beam 3. The first hook moving device 5 can adopt a screw, a hydraulic cylinder and other devices to push one end of the first hook 4 to move in the transverse direction along the hoisting beam 3. The other end of the first hook 4 is located below the hoisting beam 3 and is designed as a suitable clamping mechanism (such as a clamp, a locking mechanism, etc.) to clamp one end of the pipe pile 1. The structure of the second hook 6 is similar to that of the first hook 4, and its installation position is above the second end 302 of the hoisting beam 3. The second hook 6 is also moved in the transverse direction of the hoisting beam 3 by the second hook moving device 7. The working principle of the second hook moving device 7 is the same as that of the first hook moving device 5, ensuring that the two hooks can move synchronously or independently. The lower end of the second hook 6 is also provided with a clamping mechanism for cooperating with the first hook 4 to clamp the other end of the pipe pile 1 .

[0045] In actual operation, when it is necessary to hoist the pipe pile 1, first start the first hook moving device 5 and the second hook moving device 7 to move the first hook 4 and the second hook 6 to the appropriate positions at the two ends of the hoisting beam 3. Then, place the pipe pile 1 between the two clamping mechanisms at the other ends of the first hook 4 and the second hook 6. Then, start the first hook moving device 5 and the second hook moving device 7 again to move the two hooks to the middle at the same time until the clamping mechanisms of the first hook 4 and the second hook 6 tightly clamp the two ends of the pipe pile 1. The rope 901 connects the first hook 4 and the second hook 6 with the hammer 8, which plays the role of pulling and limiting the first hook 4 and the second hook 6, and then uses the lifting force of the hammer 8 to hoist the pipe pile 1 to the predetermined position.

[0046] The entire hoisting process is automated, eliminating the need for manual labor, significantly improving operational efficiency and safety, and reducing safety risks caused by improper operation or environmental factors. In addition, the automatic loading and unloading hoisting frame has a compact structure, easy operation, low maintenance cost, and good economy and applicability.

[0047] Reference Figure 2 In a specific embodiment, the lifting beam 3 includes a first lifting cross arm 303 and a second lifting cross arm 304, the first lifting cross arm 303 is installed on one side of the fixed center frame 2, and the second lifting cross arm 304 is installed on the other side of the fixed center frame 2, and the first lifting cross arm 303 and the second lifting cross arm 304 are located on opposite sides of the fixed center frame 2.

[0048] In this embodiment, the hoisting cross beam 3 is configured as two independent parts, namely, a first hoisting cross arm 303 and a second hoisting cross arm 304, so that the structure of the hoisting cross beam 3 is more flexible and can adapt to different installation environments and operation requirements. The first hoisting cross arm 303 is installed on one side of the fixed center frame 2 and can be fixed at a predetermined position of the fixed center frame 2 by welding, bolt connection or other fastening methods. The length and strength of the first hoisting cross arm 303 are determined according to actual needs to ensure that it can bear the weight of the pipe pile 1 and maintain stability during the hoisting process. Corresponding to the first hoisting cross arm 303, the second hoisting cross arm 304 is installed on the other side of the fixed center frame 2, that is, located at the relative position of the first hoisting cross arm 303. The installation method of the second hoisting cross arm 304 is the same as that of the first hoisting cross arm 303, ensuring that the two form a symmetrical layout on both sides of the fixed center frame 2.

[0049] The double cross arm design of the first hoisting cross arm 303 and the second hoisting cross arm 304 not only enhances the overall rigidity and stability of the hoisting cross beam 3, but also improves the balance and safety of the hoisting process. At the same time, this design makes the hoisting frame more adaptable to the hoisting requirements of pipe piles 1 of different lengths, and improves the versatility and flexibility of the hoisting frame.

[0050] Reference Figure 3 In a specific embodiment, the first lifting cross arm 303 is installed on one side of the fixed center frame 2 through a first movable pin 305, and the second lifting cross arm 304 is installed on the other side of the fixed center frame 2 through a second movable pin 306.

[0051] In this specific embodiment, the first hoisting cross arm 303 is installed on one side of the fixed center frame 2 through the first movable pin 305, so that the first hoisting cross arm 303 can be rotated or fine-tuned to a certain extent to adapt to different working angles and pipe pile 1 hoisting requirements. The above-mentioned first movable pin 305 is a pin shaft with a locking function, which allows fine-tuning within a certain range after being inserted and locked. One end of the pin shaft is fixed in a preset hole of the fixed center frame 2, and the other end passes through the corresponding hole on the first hoisting cross arm 303 and is fixed by a locking mechanism (such as a nut, a retaining ring, etc.). Similar to the first hoisting cross arm 303, the second hoisting cross arm 304 is also installed on the other side of the fixed center frame 2 through the second movable pin 306. The structure and function of the second movable pin 306 are the same as those of the first movable pin 305. Through the installation method of the movable pin, the first hoisting cross arm 303 and the second hoisting cross arm 304 can flexibly adjust the angle and position, so that the hoisting frame can be applied to more types of pipe pile 1 hoisting operations.

[0052] Reference Figure 3-Figure 7In a specific embodiment, the first hoisting cross arm 303 includes a first cross arm component 3031 and a second cross arm component 3032. The first cross arm component 3031 is installed on one side of the fixed center frame 2. The first cross arm component 3031 is provided with a plurality of first positioning through holes 3033 distributed laterally. The second cross arm component 3032 is provided with a second positioning through hole 3034. The second positioning through hole 3034 is aligned with one of the first positioning through holes 3033 and fixed by a first positioning pin 307.

[0053] The second lifting cross arm 304 includes a third cross arm component 3041 and a fourth cross arm component 3042. The third cross arm component 3041 is installed on the other side of the fixed center frame 2. The third cross arm component 3041 is provided with a plurality of laterally distributed third positioning through holes 3043. The fourth cross arm component 3042 is provided with a fourth positioning through hole 3044. The fourth positioning through hole 3044 is aligned with one of the third positioning through holes 3043 and fixed by a second positioning pin 308.

[0054] In this embodiment, the first cross arm assembly 3031 is one of the bearing parts of the first hoisting cross arm 303, and is installed on one side of the fixed center frame 2. On the first cross arm assembly 3031, a plurality of first positioning through holes 3033 are distributed along its length direction (i.e., transverse direction). The design of these through holes allows flexible connection and positioning with the second cross arm assembly 3032 to meet different hoisting requirements.

[0055] The second cross arm assembly 3032 is an extension or adjustable part of the first hoisting cross arm 303, and also plays a bearing role. A second positioning through hole 3034 is provided on the second cross arm assembly 3032. A plurality of second positioning through holes 3034 can be provided, or only one second positioning through hole 3034 can be provided. The size of the second positioning through hole 3034 matches that of the first positioning through hole 3033.

[0056] By selecting a suitable first positioning through hole 3033 and aligning with the second positioning through hole 3034, and using the first positioning pin 307 to pass through the two through holes for fixing, the first cross arm assembly 3031 and the second cross arm assembly 3032 are firmly connected together. This design allows the total length of the first hoisting cross arm 303 to be adjusted according to actual needs, thereby improving the flexibility of the hoisting operation.

[0057] The structure of the second hoisting cross arm 304 is similar to that of the first hoisting cross arm 303. It is located on the other side of the fixed center frame 2 and includes a third cross arm assembly 3041 and a fourth cross arm assembly 3042. The third cross arm assembly 3041 is similar to the first cross arm assembly 3031. On the third cross arm assembly 3041, a plurality of third positioning through holes 3043 are distributed along its length direction, which are used to connect and position with the fourth cross arm assembly 3042. The fourth cross arm assembly 3042 is an extension or adjustable part of the second hoisting cross arm 304, and is provided with a fourth positioning through hole 3044. The fourth positioning through hole 3044 matches the third positioning through hole 3043 to achieve accurate alignment and fixation. By selecting a suitable third positioning through hole 3043 to align with the fourth positioning through hole 3044, and using the second positioning pin 308 to pass through the two through holes for fixing, the third cross arm assembly 3041 and the fourth cross arm assembly 3042 are firmly connected together.

[0058] Before hoisting, according to the length of the pipe pile 1 and the hoisting requirements, the first positioning through hole 3033 and the second positioning through hole 3034 as well as the third positioning through hole 3043 and the fourth positioning through hole 3044 can be selected to align and fix with positioning pins. In this way, the length of the first hoisting cross arm 303 and the second hoisting cross arm 304 can be adjusted as needed to adapt to the hoisting operation of pipe piles 1 of different specifications.

[0059] Reference Figure 1-Figure 3 In a specific embodiment, a first limit block 309 is provided at the upper end head of the first end 301 of the lifting beam 3 , and a second limit block 310 is provided at the upper end head of the second end 302 of the lifting beam 3 .

[0060] In this specific embodiment, the above-mentioned first limit block 309 is located at the upper end head of the first end 301 of the lifting beam 3, and is firmly installed on the beam by welding, bolt connection or other reliable fixing methods, so as to ensure that the excessive movement of the first hook 4 can be effectively limited during the lifting process.

[0061] Similar to the first stopper 309, the second stopper 310 is located at the upper end of the second end 302 of the hoisting beam 3 and is mounted on the beam in the same fixing manner. Its position and function correspond to those of the first stopper 309, and together they provide safety protection for the hoisting operation.

[0062] By providing the first limit block 309 and the second limit block 310, accidental falling off or excessive movement of the hoisting components during the hoisting process is effectively prevented, thereby greatly reducing the risk of accidents.

[0063] In a specific embodiment, the first hook moving device 5 is a first hydraulic cylinder, one end of which is mounted on the upper surface of the hoisting beam 3, and the other end of which is connected to one end of the first hook 4;

[0064] The second hook moving device 7 is a second hydraulic cylinder, one end of which is mounted on the upper surface of the hoisting beam 3, and the other end of which is connected to one end of the second hook 6;

[0065] A first oil inlet pipe 902 and a first oil return pipe 903 are provided on the first hydraulic cylinder, and the first oil inlet pipe 902 and the first oil return pipe 903 are connected to the photovoltaic pile driver; a second oil inlet pipe 904 and a second oil return pipe 905 are provided on the second hydraulic cylinder, and the second oil inlet pipe 904 and the second oil return pipe 905 are connected to the photovoltaic pile driver.

[0066] In this specific embodiment, the first hook moving device 5 is designed as a first hydraulic cylinder. The hydraulic cylinder is suitable for driving the lateral movement of the first hook 4 with its efficient and stable power output characteristics. One end of the first hydraulic cylinder is firmly mounted on the upper surface of the lifting beam 3. In order to ensure the stability of the installation, welding, bolt connection or other reliable fixing methods can be used. The installation position should be selected at a position relatively central to the upper surface of the lifting beam 3 and with reasonable force, so as to better drive the first hook 4. The other end of the first hydraulic cylinder is connected to one end of the first hook 4 through a suitable connector (such as a pin, a connecting rod, etc.) so that the first hook 4 can move smoothly laterally with the extension and retraction of the first hydraulic cylinder. The structure and installation method of the above-mentioned second hook moving device 7 are similar to those of the first hook moving device 5, but are located on the other side of the lifting beam 3.

[0067] The first hydraulic cylinder is provided with a first oil inlet pipe 902 and a first oil return pipe 903. The two oil pipes are used to provide high-pressure oil to the first hydraulic cylinder and recover low-pressure oil, respectively. The other ends of the first oil inlet pipe 902 and the first oil return pipe 903 are connected to the hydraulic system of the photovoltaic pile driver so as to drive the operation of the first hydraulic cylinder through the power source of the photovoltaic pile driver. The hydraulic system of the photovoltaic pile driver is a prior art, and the utility model will not be described in detail here.

[0068] The second hydraulic cylinder is provided with a second oil inlet pipe 904 and a second oil return pipe 905, which are connected in the same manner as the first hydraulic cylinder. The two oil pipes are also connected to the hydraulic system of the photovoltaic pile driver to realize the power supply and oil recovery of the second hydraulic cylinder.

[0069] Reference Figure 3In a specific embodiment, the first hook 4 includes a first sliding portion 401, a first horizontal portion 402, a first vertical portion 403 and a first hook straight portion 404 which are connected in sequence from one end of the first hook 4 to the other end of the first hook 4, the first sliding portion 401 is connected to the first hook moving device 5, and the first sliding portion 401 moves along the transverse direction of the hoisting beam 3 under the push of the first hook moving device 5;

[0070] The second hook 6 includes a second sliding portion 601, a second horizontal portion 602, a second vertical portion 603 and a second hook straight portion 604 which are connected in sequence from one end of the second hook 6 to the other end of the second hook 6. The second sliding portion 601 is connected to the second hook moving device 7. The second sliding portion 601 moves along the transverse direction of the lifting beam 3 under the push of the second hook moving device 7.

[0071] In this embodiment, the design of the first hook 4 and the second hook 6 meets the requirements of movement, positioning and clamping of the hook during the lifting process. Take the first hook 4 as an example for specific description, wherein the first sliding portion 401 is a key component connected to the first hook moving device 5 (i.e., the first hydraulic cylinder), and the first sliding portion 401 is designed to be able to slide smoothly along the transverse direction of the lifting beam 3. In a specific embodiment, the first sliding portion 401 may also include a connecting hole or a pin hole that matches the piston rod of the hydraulic cylinder, and a guide device (such as a slide rail, a slider, etc.) to ensure smooth sliding. Under the push of the hydraulic cylinder, the first sliding portion 401 can drive the entire first hook 4 to move along the transverse direction of the lifting beam 3. The above-mentioned first transverse portion 402 mainly plays the role of providing a transverse space for the movement of the first hook 4. The first vertical portion 403 extends downward from the first horizontal portion 402 (it can be vertical or extend downward at a certain arc), and the first vertical portion 403 provides the first hook 4 with the necessary vertical height so that the first hook 4 can smoothly hook and lift the pipe pile 1 during the lifting process. The first hook straight portion 404 is the end portion of the first hook 4, which is used to firmly clamp the pipe pile 1 and bear its weight. When in use, the first hook straight portion 404 is inserted into the interior of the pipe pile 1.

[0072] The structure of the second hook 6 is similar to that of the first hook 4, but is located on the other side of the hoisting beam 3. The parts it contains are also similar to those of the first hook 4.

[0073] During the hoisting process, by controlling the hydraulic system of the photovoltaic pile driver, high-pressure oil can be provided to the first hydraulic cylinder and the second hydraulic cylinder respectively, so that they can drive the first hook 4 and the second hook 6 to move laterally. As the hydraulic cylinders extend and retract, the first sliding part 401 and the second sliding part 601 will move in the lateral direction of the hoisting beam 3 respectively, thereby driving the entire first hook 4 and the second hook 6 to reach a predetermined position. Then, by adjusting the angle and position of the straight part of the hook, the straight part of the hook can be smoothly inserted into the interior of the pipe pile 1, and then further controlled by the hydraulic cylinder, the first hook 4 and the second hook 6 are pulled back inward (toward the center direction of the fixed center frame 2), thereby clamping and lifting the pipe pile 1.

[0074] In a specific embodiment, the transverse length of the first transverse portion 402 ranges from 200 mm to 600 mm, and the transverse length of the second transverse portion 602 ranges from 200 mm to 600 mm.

[0075] In a specific embodiment, the longitudinal height of the first vertical portion 403 is greater than the sum of the longitudinal height of the lifting beam 3 and the height of the first sliding portion 401 , and the longitudinal height of the second vertical portion 603 is greater than the sum of the longitudinal height of the lifting beam 3 and the height of the second sliding portion 601 .

[0076] In a specific embodiment, the transverse length of the first hook straight portion 404 ranges from 100 mm to 300 mm, and the transverse length of the second hook straight portion 604 ranges from 100 mm to 300 mm.

[0077] In this specific embodiment, the specific values ​​of the transverse length range of the first transverse portion 402 and the transverse length range of the second transverse portion 602 need to be determined according to the actual application scenario and hoisting requirements, so as to provide sufficient stability and support for the first hook 4 during the hoisting process. Therefore, a reasonable transverse length range may be from 200mm to 600mm. As a preferred specific embodiment, the transverse length of the first transverse portion 402 and the second transverse portion 602 can be 400mm, at which time the transverse movement range of the first transverse portion 402 and the second transverse portion 602 on the hoisting beam can reach 300mm (the transverse width of the first sliding portion and the second sliding portion and the steel plate width of the hook itself need to be deducted).

[0078] The longitudinal height of the first vertical portion 403 is designed to be greater than the sum of the longitudinal height of the hoisting beam 3 and the height of the first sliding portion 401. Such a design can ensure that during the hoisting process, the first hook straight portion 404 has enough space to hook and lift the pipe pile 1 without being interfered by the hoisting beam 3 or the first sliding portion 401. The longitudinal height of the second vertical portion 603 is the same as that of the first vertical portion 403. Specifically, a reasonable longitudinal range may be from 200 mm to 500 mm, and in a specific embodiment, it may be 290 mm.

[0079] The specific values ​​of the transverse length range of the first hook straight portion 404 and the second hook straight portion 604 are also determined based on the actual application scenario and hoisting requirements, so as to firmly hook the pipe pile 1 and bear its weight. At the same time, various factors that may be encountered during the hoisting process, such as wind force, vibration, etc., should also be considered. Therefore, a reasonable transverse length range may be from 100 mm to 300 mm, and in a specific embodiment, it may be 180 mm.

[0080] In a specific embodiment, the first hook 4 and the second hook 6 are both made of steel plates. For example, steel plates with a thickness of 25 mm and a width of 60 mm may be used.
