Description

Technical Field

[0001] This invention relates to the field of auxiliary hoisting equipment technology, specifically an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic power plants. Background Technology

[0002] In the construction of high-altitude photovoltaic power stations, large-blade helical steel piles are widely used as the foundation structure for photovoltaic supports due to their excellent load-bearing capacity and adaptability to complex terrain. These helical steel piles typically employ a large-diameter blade design, resulting in a long pile body and significant self-weight. During construction, they need to be transferred from their transport state to the drilling location using hoisting equipment, and then screwed into the soil in conjunction with the drilling rig. Currently, common hoisting methods for helical steel piles involve binding them with slings or ropes, relying on manual assistance to adjust the pile's posture and position. During the hoisting phase, the hoisting equipment lifts the horizontally placed helical steel pile, and then the pile is gradually adjusted to a vertical position by manual pushing or using the boom's luffing mechanism before being connected to the drilling rig's power head or flange.

[0003] However, high-altitude areas often experience harsh weather conditions such as strong winds and low oxygen levels. Existing hoisting methods, relying on manual assistance to adjust the posture of large-diameter spiral steel piles, are not only labor-intensive and inefficient but also pose significant safety risks. Firstly, the sling binding method is prone to slippage during the transition from horizontal to vertical, leading to loss of pile posture control or collisions with surrounding equipment. Secondly, existing hoisting equipment only has lifting capabilities and lacks the ability to actively control the pile's posture, failing to stabilize it in the precise position required for alignment after it is verticalized. When the drilling rig is connected to the upper flange of the pile, manual support is required. However, the pile, due to its large overall mass or large blades, is often significantly affected by wind, causing swaying, resulting in alignment difficulties, prolonged time consumption, and severely impacting construction progress.

[0004] Furthermore, even after the drilling rig and the flange of the spiral steel pile are successfully connected, the existing suspension device usually completely disengages after the pile is aligned during subsequent drilling and tightening operations. When completely disengaged, the pile lacks lateral support in the initial stage of tightening into the soil, making it prone to tilting due to uneven ground or uneven force applied by the drilling rig. This requires repeated calibration by personnel, which in turn affects the construction quality and efficiency.

[0005] To address this, an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic power plant areas is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic plant areas. This device addresses the problems in existing technologies, such as the risk of slippage after the slings are tied to the spiral steel pile, resulting in loss of posture control after hoisting, requiring manual adjustment, and the tendency to sway when aligned with the drilling machine after hoisting to the designated position, leading to alignment difficulties and affecting construction efficiency and quality.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The clamping motor rotates forward, driving the lifting block upward. First, the clamping plate and the clamping ring move closer together to clamp the spiral steel pile. After clamping, the lower pressure block overcomes the spring force of the clamping spring, moving the pile upward to complete the automatic lifting. After the upper end of the clamping plate is in contact with the fixing frame, the fixing frame pushes the vertical insertion block downward. The vertical insertion component causes the clamping ring to rotate around the fixing column to a vertical position, which is then locked by the locking unit. Simultaneously, the fixing component locks the lower pressure block, achieving automatic adjustment of the pile's posture. During the tightening operation, the clamping motor reverses, causing the clamping plate and clamping ring to loosen briefly. The guide wheel, with the cooperation of the guiding component and the stabilizing unit, remains in contact with the pile and provides lateral support, ensuring construction quality. After tightening is completed, the clamping motor continues to reverse, the clamping plate pushes the horizontal push plate to unlock the lower pressure block. The lower pressure block quickly moves downward, causing the clamping rings to come into contact with each other. The reset component releases the vertical lock, and the clamping rings return to a horizontal position under the action of the torsion spring, preparing for the next use. Attached Figure Description

Detailed Implementation

[0020] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more readily understood, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 3This invention provides an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic power plants, used in conjunction with a rigid guide column crane. It includes a fixed frame 1, a lifting block 2, a lower pressure block 3, a clamping component 4, a clamping plate 5, a clamping ring 6, a vertical placement component 8, a fixing component 9, a guide wheel 10, a guiding component 11, and a reset component 12. The fixed frame 1 is fixedly connected to the lower end of the rigid guide column of the crane. The lifting block 2 is slidably connected to the front end of the fixed frame 1. Two sets of lower pressure blocks 3, clamping plates 5, and clamping rings 6 are provided, symmetrically arranged on the left and right sides of the lifting block 2. The lower pressure block 3 is slidably connected to the fixed frame 1. The clamping plate 5 is connected to the lifting block 2 via the clamping component 4. The clamping ring 6 is connected to the side of the two sets of clamping plates 5 that are close to each other. The clamping component 4 is used to cooperate with the lower pressure block 3 when the lifting block 2 moves upward. The clamping plate 5 and the clamping ring 6 are brought close together to clamp the spiral steel pile, and after clamping, the spiral steel pile is moved upward. The vertical component 8 is set inside the clamping plate 5, and the fixing component 9 is set inside the fixing frame 1. After the spiral steel pile moves to the designated position, the fixing component 9 locks the lower pressure block 3. At the same time, with the cooperation of the fixing frame 1, the vertical component 8 makes the clamping ring 6 rotate relative to the clamping plate 5 to a certain angle and then locks it. The guide wheel 10 is connected to the clamping ring 6 through the guide component 11. The guide component 11 is used to ensure that the guide wheel 10 fits and supports the spiral steel pile when the clamping rings 6 move away from each other within the designated range. The reset component 12 is set inside the clamping ring 6. The reset component 12 is used to unlock the lower pressure block 3 with the cooperation of the fixing component 9 when the clamping rings 6 move away from each other outside the designated range, and reset the clamping rings 6 after they fit together.

[0022] The purpose of using a rigid guide column crane is that the rigid guide column crane has the characteristics of high vertical movement accuracy and strong resistance to lateral loads, which can provide a stable installation base and precise lifting guidance for auxiliary lifting devices. During the process of the helical steel pile changing from a horizontal to a vertical position, the rigid guide column can effectively withstand the lateral impact load generated by the pile's posture change, avoiding alignment deviation caused by the swaying of the flexible boom; at the same time, during the screwing and drilling operation, the rigid guide column can ensure that the lifting device and the drilling machine maintain a precise relative position, making the lateral support provided by the guide wheel 10 stable and reliable, thereby giving full play to the functional advantages of the device in automatic clamping, posture adjustment and screwing support.

[0023] Please see Figures 1 to 2Specifically, the clamping component 4 includes a clamping motor 41, a clamping screw 42, a clamping limiting groove 43, a clamping spring 44, an upper clamping connecting rod 45, a lower clamping connecting rod 46, a clamping connecting arm 47, a clamping sliding groove 48, and a clamping protrusion 49. The clamping motor 41 is fixedly connected to the fixed frame 1, and the clamping screw 42 is rotatably connected to the front end of the fixed frame 1. The upper ends of the clamping motor 41 and the clamping screw 42 are connected. The rear end of the lifting block 2 is slidably engaged with the front end of the fixed frame 1, and the center of the lifting block 2 is engaged with the clamping screw 42. This engagement means that when the clamping motor 41 drives the clamping screw 42 to rotate forward, the lifting block... Block 2 can move upward under the sliding limit of the fixed frame 1 and the screw cooperation between the center and the clamping screw 42. When the clamping screw 42 reverses, it moves downward. The clamping limit groove 43 is opened on the fixed frame 1. The lower pressing block 3 is slidably connected to the clamping limit groove 43. The upper and lower ends of the clamping spring 44 abut against the upper end of the lower pressing block 3 and the inner wall of the fixed frame 1, respectively. The two ends of the upper clamping connecting rod 45 and the lower clamping connecting rod 46 are rotatably connected to the lifting block 2 and the clamping connecting arm 47, respectively. The upper clamping connecting rod 45 and the lower clamping connecting rod 46 are of the same length. The clamping connecting arm 47 is fixedly connected to the upper end of the clamping plate 5. A groove 48 is formed on the upper clamping connecting rod 45, and a clamping protrusion 49 is located at the front end of the lower pressure block 3. The clamping protrusion 49 cooperates with the clamping groove 48. This cooperation means that the clamping protrusion 49 is embedded in the clamping groove 48. In the initial stage when the clamping motor 41 drives the lifting block 2 to move upward, due to the elastic force of the clamping spring 44 at the upper end of the lower pressure block 3, the lower pressure block 3 and the clamping protrusion 49 will be temporarily fixed relative to the fixed frame 1. Meanwhile, the upper clamping connecting rods 45 on both sides of the lifting block 2 will move upward with the lifting block 2, so that the upper clamping connecting rods 45 are in sliding cooperation with the clamping protrusion 49 and the clamping groove 48. The upper clamping link 45 is swung, causing the clamping plates 5 to move closer together. When the clamping rings 6 at the two clamping plates 5 are in contact with each other, or when the clamping rings 6 have clamped the spiral steel pile and can no longer move closer together, the clamping protrusion 49 can no longer slide in the clamping groove 48 to move the clamping plates 5 closer together. Therefore, as the lifting block 2 continues to move upward, the lower pressure block 3 will overcome the elastic force of the clamping spring 44, causing the lifting block 2 to move the upper clamping link 45, the lower clamping link 46, the clamping protrusion 49, the lower pressure block 3, the clamping plates 5, the clamping rings 6, and the spiral steel pile upward together.

[0024] In actual use, when it is necessary to transfer the horizontally placed large-blade spiral steel pile from the transport state to the drilling position, the operator starts the clamping motor 41 to rotate forward. The clamping motor 41 drives the lifting block 2 to move upward along the fixed frame 1 through the clamping screw 42. In the initial stage of the lifting block 2 moving upward, the clamping spring 44 at the upper end of the lower pressure block 3 keeps it relatively fixed to the fixed frame 1, and the lower pressure block 3 and the clamping protrusion 49 cannot move temporarily. However, the upper clamping connecting rods 45 on both sides of the lifting block 2 move upward with the lifting block 2, so that the upper clamping connecting rods 45 swing under the sliding cooperation of the clamping protrusion 49 and the clamping slide groove 48, thereby bringing the clamping plates 5 closer to each other. When the clamping rings 6 at the clamping plates 5 on both sides clamp the spiral steel pile and can no longer move closer together, the clamping protrusion 49 can no longer slide within the clamping groove 48 to move the clamping plates 5 closer together. Therefore, as the lifting block 2 continues to move upward, the lower pressure block 3 will overcome the elastic force of the clamping spring 44, causing the lifting block 2 to move the upper clamping connecting rod 45, the lower clamping connecting rod 46, the clamping protrusion 49, the lower pressure block 3, the clamping plates 5, the clamping rings 6, and the spiral steel pile upward together, achieving automatic lifting after clamping the spiral steel pile. The design of clamping the spiral steel pile with the clamping rings 6 replaces the traditional binding lifting method, avoiding the risk of loss of posture or collision with surrounding equipment due to slippage of the slings during the lifting process. It solves the problems of high labor intensity and high safety hazards of manual adjustment in high-altitude and strong wind environments, and realizes automatic clamping and stable lifting of the spiral steel pile.

[0025] Example 2: Please refer to Figures 3 to 8This invention provides an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic power plant areas. The device includes a vertical placement component 8, which comprises a fixed slot 81, a movable slot 82, a fixed column 83, a locking unit 84, a movable column 85, a movable groove 86, a movable plate 87, a movable spring 88, a vertical placement slot 89, a vertical placement block 810, a block baffle 811, a block spring 812, and a block chamfer 813. The fixed slot 81 and movable slot 82 are located on the side of the clamping ring 6 near the clamping plate 5, and the fixed column 83 is fixedly connected to... On the side of the clamping plate 5 near the clamping ring 6, the fixing post 83 is rotatably connected to the fixing slot 81. The locking unit 84 is disposed inside the clamping ring 6. The locking unit 84 is used to relock the clamping ring 6 onto the clamping plate 5 after the clamping ring 6 rotates around the fixing post 83 to a certain angle. The movable slot 86 is opened inside the clamping plate 5. The movable plate 87 is slidably connected to the movable slot 86. The movable post 85 is fixedly connected to the movable plate 87 on the side near the clamping ring 6. The movable post 85 is inserted into the movable slot 82. The two ends of the movable spring 88 are respectively connected to... The movable plate 87 abuts against the side away from the clamping ring 6 and the inner wall of the clamping plate 5. The vertical slot 89 is located at the upper end of the movable slot 86. The vertical insert 810 is slidably connected in the vertical slot 89. The insert baffle 811 is located on the side of the vertical insert 810. The upper and lower ends of the insert spring 812 abut against the lower end of the insert baffle 811 and the inner wall of the clamping plate 5, respectively. The insert chamfer 813 is located at the lower end of the vertical insert 810. The upper end of the vertical insert 810 cooperates with the fixed frame 1. This cooperation means that when the clamping plate 5 moves up to cooperate with the fixed frame... After the bottom contacts, the bottom of the fixed frame 1 presses down against the upper end of the vertically placed insert 810, causing the vertically placed insert 810 to move downward against the insert spring 812. The chamfer 813 of the insert engages with the movable plate 87. This engagement means that when the vertically placed insert 810 moves downward, the chamfer 813 at its lower end contacts the movable plate 87. Through the inclined engagement, the movable plate 87 is pushed to slide horizontally in the movable groove 86 and compress the movable spring 88. The movable plate 87 drives the movable column 85 to move horizontally, causing the movable column 85 to disengage from the movable slot 82.

[0026] Specifically, when the clamping plate 5 rises with the lifting block 2 to contact the fixed frame 1, the fixed frame 1 presses down the vertical insertion block 810. The vertical insertion block 810, through its lower end chamfer 813, pushes the movable plate 87 and the movable column 85 to move horizontally, thereby releasing the horizontal limit on the clamping ring 6. At this time, under the action of gravity and the weight of the pile, the clamping ring 6 automatically rotates downward around the fixed column 83, realizing the change of the pile body's posture from horizontal to vertical.

[0027] Please see Figures 5 to 6Specifically, the locking unit 84 includes a locking insert 841, a locking groove 842, a locking block 843, a locking spring 844, and a locking slot 845. The locking insert 841 is fixedly connected to the upper end of the fixing post 83. The locking groove 842 is opened at the upper end of the fixing slot 81. The locking block 843 is slidably connected in the locking groove 842. The two ends of the locking spring 844 abut against the inner wall of the clamping ring 6 and the end of the locking block 843 away from the fixing slot 81, respectively. The locking slot 845 is opened at the lower end of the locking block 843. The locking insert 841 and the locking slot 845 are inserted and engaged. The coordination here refers to the following: when the clamping ring 6 rotates around the fixed post 83 to a vertical position, the locking block 843 will rotate with the clamping ring 6 to a position directly opposite the locking insert 841 of the fixed post 83. During the rotation, the locking insert 841 will first contact the locking block 843 and push the locking block 843 to move away from the fixed slot 81, and squeeze the locking spring 844 until the locking slot 845 of the locking block 843 is directly opposite the locking insert 841. At this time, the locking block 843 is reset by the action of the locking spring 844, so that the locking insert 841 is inserted into the locking slot 845, and the clamping ring 6 and the clamping plate 5 are fixed relative to each other.

[0028] Specifically, when the clamping ring 6 rotates the pile to a vertical position, the locking block 841 on the fixed column 83 is aligned with the locking slot 845 at the lower end of the locking block 843. The locking block 843 moves downward under the action of the locking spring 844, so that the locking block 841 is inserted into the locking slot 845, thereby relocking the clamping ring 6 and the clamping plate 5, providing the pile with a stable ability to maintain a vertical position, preventing it from swaying due to wind and other factors, and creating conditions for subsequent precise alignment with the drilling machine.

[0029] The rest of the structure is the same as in Example 1.

[0030] In actual use, when the upper end of the clamping plate 5 moves upward with the lifting block 2 and contacts the bottom of the fixed frame 1, the bottom of the fixed frame 1 presses down against the upper end of the vertical insertion block 810, causing the vertical insertion block 810 to move downward against the insertion block spring 812. When the vertical insertion block 810 moves downward, the chamfer 813 at its lower end contacts the movable plate 87, and through the inclined surface cooperation, pushes the movable plate 87 to slide horizontally in the movable groove 86, compressing the movable spring 88. The movable plate 87 drives the movable column 85 to move horizontally, causing the movable column 85 to disengage from the movable slot 82 on the clamping ring 6, thereby releasing the horizontal limit on the clamping ring 6. At this time, under the weight of itself and the spiral steel pile, the clamping ring 6 rotates downward about the fixed column 83 as the axis. During rotation, locking block 841 first contacts locking block 843 and pushes locking block 843 away from the fixed slot 81, squeezing locking spring 844 until the clamping ring 6 rotates to a vertical position. At this point, the locking slot 845 of locking block 843 is aligned with locking block 841. Locking block 843 is then reset under the action of locking spring 844, allowing locking block 841 to insert into locking slot 845, thus fixing clamping ring 6 and clamping plate 5. The spiral steel pile is then stably held in a vertical position. This achieves automatic conversion and locking of the spiral steel pile from a horizontal to a vertical position without manual pushing or assistance. It solves the problems of high labor intensity, low work efficiency, and significant safety risks associated with manually adjusting the posture of large-sized spiral steel piles in high-altitude areas. Furthermore, it automatically locks after posture conversion, providing a stable vertical state maintenance capability for subsequent precise alignment with the drilling machine, effectively preventing alignment difficulties caused by pile swaying due to wind and other factors.

[0031] Example 3: Please refer to Figures 8 to 9This invention provides an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic power plants. The device includes a fixing component 9, which comprises an upper push groove 91, an upper push block 92, an upper push baffle 93, an upper push spring 94, an upper push slot 95, a horizontal push groove 96, a horizontal push block 97, a horizontal push baffle 98, a horizontal push spring 99, a holding limit groove 910, a holding limit plate 911, an upper push chamfer 912, a reset spring 913, a holding slot 914, a holding groove 915, a holding block 916, a holding chamfer 917, and a holding spring 918. The upper push groove 91 is formed within a fixing frame 1. The upper push block 92 is slidably connected within the upper push groove 91. The upper push baffle 93 is disposed on the side of the upper push block 92. The upper and lower ends of the upper push spring 94 are respectively connected to the inner wall of the fixing frame 1 and the upper push baffle 918. 3. The upper end abuts against the upper push slot 95, which is opened on the side of the upper push block 92. The horizontal push groove 96 is opened on the side of the upper push groove 91 away from the center of the fixed frame 1. The horizontal push block 97 is slidably connected in the horizontal push groove 96. The horizontal push baffle 98 is set at the lower end of the horizontal push block 97. The two ends of the horizontal push spring 99 abut against the side of the horizontal push baffle 98 away from the center of the fixed frame 1 and the inner wall of the fixed frame 1, respectively. The lower end of the upper push block 92 cooperates with the upper end of the clamping plate 5. The cooperation here means that when the clamping plate 5 moves up with the lifting block 2 to the designated position, the upper end of the clamping plate 5 contacts the lower end of the upper push block 92 and continues to move up, pushing the upper push block 92 to slide upward against the upper push spring 94. The side of the horizontal push block 97 near the center of the fixed frame 1 is inserted into the upper push slot 95. The cooperation here means that the upper push block 92 slides upward. When the push-up slot 95 and the push-down block 97 are aligned, the push-down block 97 moves towards the center of the fixed frame 1 under the action of the push-down spring 99 and inserts into the push-up slot 95, locking the push-up block 92 at the current height. The maintaining limit groove 910 is opened at the upper end of the push-up slot 91, and the maintaining limit plate 911 is slidably connected in the maintaining limit groove 910. The left and right ends of the reset spring 913 abut against the end of the maintaining limit plate 911 away from the center of the fixed frame 1 and the inner wall of the fixed frame 1, respectively. The push-up chamfer 912 is set at the upper end of the push-up block 92, and the push-up chamfer 912 cooperates with the side of the maintaining limit plate 911 near the center of the fixed frame 1. The cooperation here means that when the push-up block 92 slides upward, the push-up chamfer 912 at its upper end cooperates with the maintaining limit plate 911 near the center of the fixed frame 1. One end contacts the retaining plate 911, which, through the inclined surface engagement, pushes the retaining limiting plate 911 to move horizontally away from the center of the fixing frame 1, overcoming the reset spring 913. Multiple retaining slots 914 are provided, located on the side of the retaining limiting plate 911 away from the center of the fixing frame 1. A retaining groove 915 is located on the side of the lower pressure block 3 near the center of the fixing frame 1. The retaining block 916 is slidably connected within the retaining groove 915. A retaining chamfer 917 is provided on the retaining block 916. Both ends of the retaining spring 918 abut against the end of the retaining block 916 away from the center of the fixing frame 1 and the inner wall of the lower pressure block 3, respectively. The retaining chamfer 917 engages with the retaining slot 914. This engagement means that after the retaining limiting plate 911 is abutted against by the upper push block 92 on the side away from the center of the fixing frame 1...The retaining block 916 at the lower pressure block 3 will contact the retaining limiting plate 911, and the retaining block 916 will insert into the retaining slot 914. At this time, if it is desired to further move the clamping plate 5 and the lower pressure block 3 upward, so that the upper end of the clamping plate 5 is completely in contact with the lower end of the fixing frame 1, the retaining chamfer 917 will be in contact with the upper end of the retaining slot 914. As the lower pressure block 3 continues to move upward, the retaining block 916 will move away from the retaining limiting plate 911 along the retaining chamfer 917 and squeeze the retaining spring 918 until the retaining block 916 moves to the next retaining slot 914 and is reinserted into the retaining slot 914 under the action of the retaining spring 918. At this time, the clamping ring 6 will drive the spiral steel pile upward. To release the spiral steel pile at a sufficient distance from the ground, simply control the clamping motor 41 to reverse the clamping screw 42, causing the lifting block 2 to move downwards. At this point, because the holding block 916 is engaged with the holding slot 914, the holding block 916 cannot move downwards. Therefore, the lower pressure block 3 cannot move downwards with the lifting block 2. The lifting block 2, along with the upper clamping rods 45 and lower clamping rods 46 on both sides, moves downwards relative to the lower pressure block 3. Under the action of the clamping groove 48 and the clamping protrusion 49, the upper clamping rod 45 rotates upwards relative to the lifting block 2, causing the clamping plates 5 and clamping rings 6 on both sides of the upper clamping rod 45 to move away from each other, thus releasing the spiral steel pile.

[0032] Specifically, the purpose of the fixing component 9 is that when the clamping plate 5 moves upward to contact the lower end of the upper push block 92 and pushes the upper push block 92 upward, the upward chamfer 912 of the upper push block 92 pushes the maintaining limit plate 911 to move horizontally. At the same time, the upper push slot 95 aligns with the horizontal push block 97, and the horizontal push block 97 is inserted into the upper push slot 95 under the action of the horizontal push spring 99, thereby locking the upper push block 92. The upward movement of the upper push block 92 also locks the lower pressure block 3 in the current position through the cooperation of the maintaining chamfer 917 and the maintaining slot 914. After the pile is vertical, the fixing component 9 automatically locks the lower pressure block 3 onto the fixing frame 1, providing a position reference for the short-distance release of the clamping plate 5 during subsequent tightening operations, ensuring that the pile can still be effectively supported after release.

[0033] Please see Figure 9 Specifically, the guide component 11 includes a guide groove 111, a guide block 112, a guide spring 113, a guide post 114, and a stabilizing unit 115. The guide groove 111 is located at the lower end of the fixed slot 81. The guide block 112 is slidably connected in the guide groove 111. The two ends of the guide spring 113 abut against the side of the guide block 112 near the clamping plate 5 and the inner wall of the clamping ring 6, respectively. The guide post 114 is located on the side of the guide block 112 away from the clamping plate 5. The guide wheel 10 is slidably connected to the guide post 114. The stabilizing unit 115 is located between the guide groove 111 and the fixed slot 81 to cooperate with the fixed post 83 to maintain the stability of the guide post 114 when the guide post 114 extends out of the clamping ring 6.

[0034] Specifically, at one clamping ring 6, multiple sets of guide grooves 111, guide springs 113, and guide blocks 112 are provided. The guide grooves 111, guide springs 113, and guide blocks 112 are circumferentially distributed in the inner circle of the clamping ring 6. Only one set is shown in the figure. The purpose of setting multiple sets is that when the clamping ring 6 loosens the spiral steel pile a certain distance, the guide post 114 extends out of the clamping ring 6, so that when the guide wheel 10 at the guide post 114 is in contact with the clamping ring 6, the multiple sets of circumferential guide wheels 10 can support the spiral steel pile from multiple directions, so that the spiral steel pile remains vertical when it is lowered. During the tightening operation, the clamping plates 5 are separated by a small distance. At this time, although the clamping ring 6 is loosened from the pile body, the guide wheel 10 always maintains contact with the pile body surface under the action of the guide spring 113, providing lateral support force. When the guide wheel 10 is working, the stabilizing unit 115 strengthens the connection rigidity between the guide block 112 and the clamping ring 6, ensuring the stability of the support and improving the construction quality.

[0035] The stabilizing unit 115 includes a stabilizing cam 1151, a stabilizing groove 1152, a stabilizing baffle 1153, a stabilizing spring 1154, a stabilizing pressure block 1155, a stabilizing slot 1156, a support groove 1157, a support block 1158, a support spring 1159, and a support chamfer 11510. The stabilizing cam 1151 is located at the lower end of the fixing post 83. The stabilizing groove 1152 is formed between the fixing slot 81 and the guide groove 111. The stabilizing baffle 1153 is slidably connected in the stabilizing groove 1152. The two ends of the stabilizing spring 1154 are respectively connected to the stabilizing baffle 1154. The lower end of 53 abuts against the inner wall of the clamping ring 6. The stabilizing block 1155 is slidably connected in the guide groove 111. The upper end of the stabilizing block 1155 is connected to the lower end of the stabilizing baffle 1153. Multiple stabilizing slots 1156 are provided, and multiple stabilizing slots 1156 are opened at the lower end of the stabilizing block 1155. The support groove 1157 is opened at the upper end of the guide block 112. The support block 1158 is slidably connected in the support groove 1157. The two ends of the support spring 1159 abut against the lower end of the support block 1158 and the inner wall of the guide block 112, respectively. The support chamfer 11510 is provided. At the upper end of the support block 1158, the stabilizing cam 1151 engages with the stabilizing baffle 1153. This engagement means that when the clamping ring 6 rotates around the fixing post 83 to a vertical position, the clamping ring 6 will drive the stabilizing baffle 1153 to rotate together, causing the stabilizing baffle 1153 to gradually come into contact with the stabilizing cam 1151, and be pushed and pressed against the stabilizing spring 1154 by the stabilizing cam 1151 to the side away from the fixing slot 81. The support chamfer 11510 engages with the stabilizing slot 1156. This engagement means that the stabilizing baffle 1153 moves away from the fixing slot 81... When the device moves to the side, it will cause the stabilizing block 1155 to move synchronously until the stabilizing block 1155 and the guide block 112 are in contact. The support block 1158 at the guide block 112 will be inserted into the stabilizing slot 1156 at the stabilizing block 1155. When the guide block 112 moves outward from the clamping ring 6, the support block 1158 will slide out of the stabilizing slot 1156 along the support chamfer 11510. When the guide block 112 is pressed inward from the clamping ring 6, the support block 1158 will provide a stable support force to the guide block 112 with the cooperation of the stabilizing slot 1156.

[0036] The rest of the structure is the same as in Example 2.

[0037] In practical use, after the spiral steel pile is adjusted to a vertical position and successfully connected to the drilling machine, it needs to be screwed into the soil. The operator controls the clamping motor 41 to reverse, causing the lifting block 2 to move downward a short distance. Since the fixing component 9 has locked the lower pressure block 3 in the current position, when the lifting block 2 moves downward, the clamping plate 5 and the clamping ring 6 move away from each other a short distance under the action of the linkage mechanism, so that the clamping ring 6 changes from a clamped and locked state to a support state of the guide wheel 10 on the side of the spiral steel pile. When the clamping ring 6 is in a vertical state, the clamping ring 6 will drive the stabilizing baffle 1153 to rotate together, so that the stabilizing baffle 1153 gradually comes into contact with the stabilizing cam 1151 and is pulled away by the stabilizing cam 1151. When the fixed slot 81 pushes and compresses the stabilizing spring 1154, the stabilizing baffle 1153 moves away from the fixed slot 81, causing the stabilizing pressure block 1155 to move synchronously until the stabilizing pressure block 1155 is in contact with the guide block 112. Under the action of the supporting spring 1159, the support block 1158 at the guide block 112 is inserted into the stabilizing slot 1156 at the stabilizing pressure block 1155, locking the relative position of the guide block 112 and the clamping ring 6, ensuring that the guide wheel 10 remains stable under force. When the drilling machine drives the spiral steel pile to rotate and drill down, the multiple sets of circumferentially arranged guide wheels 10 provide lateral support while maintaining contact with the pile body, effectively preventing the spiral steel pile from tilting due to uneven ground or uneven force applied by the drilling machine in the early stage of screwing into the soil. This avoids the problems of traditional hoisting methods where the pile body is easily tilted after being completely detached after alignment, requiring repeated calibration by personnel. At the same time, the stabilizing unit 115 automatically changes the guide block 112 from a floating state to a locked state after the attitude change is completed, further improving the reliability of the lateral support and ensuring the construction quality and efficiency of screwing into the soil.

[0038] Example 4: Please refer to Figures 10 to 13Specifically, an auxiliary hoisting device for large-blade spiral steel piles in high-altitude photovoltaic power plants is provided, including a reset component 12. The reset component 12 includes an unlocking groove 121, an unlocking block 122, an unlocking baffle 123, an unlocking spring 124, and an unlocking chamfer 125. The unlocking groove 121 is formed on the side of the locking groove 842. The unlocking block 122 is slidably connected in the unlocking groove 121. The unlocking baffle 123 is connected to the side of the unlocking block 122 away from the clamping plate 5. The two ends of the unlocking spring 124 abut against the side of the unlocking baffle 123 near the clamping plate 5 and the inner wall of the clamping ring 6, respectively. The unlocking chamfer 125 is located on the side of the unlocking block 122 near the clamping plate 5. The clamping plate 5 cooperates with the horizontal push baffle 98. This cooperation means that after the tightening operation is completed, the clamping ring 6 exits the spiral steel pile, and the clamping motor 41 reverses to drive the clamping plates 5 to continue moving away from each other to a greater distance. At this point, the clamping plate 5 contacts the horizontal push baffle 98 and pushes the horizontal push baffle 98 to move horizontally. The horizontal push baffle 98 drives the horizontal push block 97 to move synchronously, causing the horizontal push block 97 to disengage from the upper push slot 95, releasing the lock on the upper push block 92. The upper push block 92 slides downward under the action of the upper push spring 94. When the holding limit plate 911 is reset by the reset spring 913, the holding block 916 disengages from the holding slot 914, the lower pressure block 3 unlocks and moves rapidly downward under the action of the clamping spring 44; the unlocking chamfer 125 engages with the locking block 843. This engagement means that during the rapid downward reset process, the lower pressure block 3 moves downward relative to the lifting block 2, which causes the clamping protrusion 49 of the lower pressure block 3 to quickly drive the upper clamping linkage 45 to change its angle downward, so that the clamping rings 6 on both sides come together and fit together. When the clamping rings 6 fit together, the unlocking stops at the two clamping rings 6 are activated. The plates 123 are in contact with each other and move into the clamping ring 6 while squeezing the unlocking springs 124 inside each other. When the unlocking baffle 123 moves into the clamping ring 6, it will drive the unlocking block 122 to move together. The unlocking chamfer 125 on the unlocking block 122 will first fit with the locking block 843. As the unlocking block 122 continues to move, the unlocking block 122 can push the locking block 843 away from the fixed slot 81 along the unlocking chamfer 125, thereby causing the locking insert 841 to be pulled out of the locking slot 845, releasing the vertical locking state of the clamping ring 6 and the clamping plate 5.

[0039] A torsion spring (not shown in the diagram) is provided between the fixing post 83 and the fixing slot 81. The torsion spring provides the initial reset torque for the clamping ring 6 to return from the vertical to the horizontal state, ensuring that the clamping ring 6 can reliably and smoothly reset automatically after unlocking.

[0040] The lower end of the movable column 85 is provided with a reset chamfer 851, which cooperates with the clamping ring 6. The purpose of this design is that when the clamping ring 6 is reset to the horizontal state, the reset chamfer 851 at the lower end of the movable column 85 contacts the edge of the slot of the movable slot 82. Through the beveled surface cooperation, the movable column 85 is guided to slide smoothly into the movable slot 82, realizing the precise horizontal positioning and insertion reset of the clamping ring 6 and the clamping plate 5, and avoiding jamming.

[0041] The rest of the structure is the same as in Example 3.

[0042] In actual use, after the spiral steel pile has completed pre-tightening and no longer requires auxiliary support, the operator further controls the clamping motor 41 to reverse, causing the clamping plates 5 to continue to move further apart to a greater distance, and then the clamping ring 6 is removed from the side of the spiral steel pile. When the clamping plate 5 moves to contact the horizontal push baffle 98, it pushes the horizontal push baffle 98 and the horizontal push block 97 to move horizontally, causing the horizontal push block 97 to disengage from the upper push slot 95 and releasing the lock on the upper push block 92. Subsequently, the upper push block 92 slides downward under the action of the upper push spring 94, while the holding limit plate 911 is reset under the action of the reset spring 913, causing the holding block 916 to disengage from the holding slot 914, and the lower pressure block 3 is unlocked and quickly moves downward to reset under the action of the clamping spring 44.

[0043] When the lowering block 3 moves downward rapidly, the clamping protrusion 49 drives the upper clamping linkage 45 to quickly change its angle, causing the clamping plates 5 and the clamping rings 6 on both sides to come closer together. During the clamping rings 6 coming together, the unlocking baffles 123 at the two clamping rings 6 come together and move inward into the clamping rings 6 while squeezing the unlocking springs 124 inside. As the unlocking baffles 123 move inward into the clamping rings 6, they drive the unlocking block 122 to move together. The unlocking chamfer 125 on the unlocking block 122 first comes into contact with the locking block 843. As the unlocking block 122 continues to move, it can push the locking block 843 away from the fixed slot 81 along the unlocking chamfer 125, thereby causing the locking insert 841 to be pulled out of the locking slot 845, releasing the vertical locking state of the clamping rings 6 and clamping plates 5. Subsequently, the clamping rings 6 automatically return to the horizontal state under the action of the torsion spring between the fixed post 83 and the fixed slot 81. When the clamping ring 6 is reset to the horizontal position, the reset chamfer 851 at the lower end of the movable column 85 contacts the edge of the slot of the movable slot 82. The movable column 85 is guided smoothly into the movable slot 82 through the inclined surface, completing the horizontal positioning and insertion reset of the clamping ring 6 and the clamping plate 5, so that the device returns to the initial state and is ready for the next hoisting operation. This realizes the automatic unlocking and reset of all actions without manual intervention, ensuring that the device can be used repeatedly, further improving construction efficiency, and avoiding the tedious operation and potential safety risks of manually disassembling the lifting equipment.
