Description

Crane system for self-installation of wind turbines and large construction equipment Technical Field

[0001] The present invention relates to the field of large equipment installation, and in particular to a boom system for autonomous installation of fans and large construction equipment. Background Art

[0002] With the development of wind power projects, wind power generation is becoming increasingly common. Wind turbine installation typically requires the use of a crane. Conventional cranes can be found in the structure described in CN 206278849 U, a mobile crawler crane. Due to the high height of wind turbines, large crawler cranes are typically used to meet the required lifting height. Small cranes cannot meet the required lifting height. However, this method also has many disadvantages: It requires the purchase of expensive large crawler cranes, which place high demands on road infrastructure and require foundation preparation for crawler crane assembly and hoisting. Crawler crane disassembly, assembly, and operation and maintenance are also cumbersome, and the installation and disassembly of large crawler cranes also requires the assistance and cooperation of small cranes. Therefore, a vehicle-mounted lifting platform that is simpler than a large crawler crane is needed. This platform can be used as a regular crane during normal operation and can independently complete all lifting operations when installing a wind turbine tower without the assistance of other cranes. It should also have a self-climbing function to meet the installation requirements of higher towers and equipment as the tower is installed, thereby simplifying the structure.

[0003] The prior art refers to the structure described in CN 208948712 U, a self-climbing crane based on a wind turbine tower body. The climbing device of this structure is relatively complex and has low practicality.

[0016] The beneficial effects of the present invention are:

[0017] 1. Avoid redundant functions and achieve high economic efficiency.

[0018] (1) Wind turbine installation method. Compared with other lifting construction methods, the significant feature of wind turbine installation is the simple and fixed relationship between the lifting point and the drop point. Specifically, wind turbine installation is generally lifted from the ground in front of the tower, and then hooked and installed step by step on the top of the tower. That is, the lifting point and the drop point do not change significantly, only the elevation of the drop point changes. This is a fixed point-to-point lifting method. This lifting method is simple in action, has low requirements for lifting equipment, and the crane structure can be relatively simple.

[0019] (2) Other lifting construction methods. This is a lifting method in which the lifting point and the drop point frequently change within the working range of the crane. In other words, the lifting point and the drop point are not fixed, which is a non-fixed point-to-point lifting method. This lifting method places high demands on the amplitude of the lifting equipment, which leads to a complex crane structure and high price. Crawler cranes are an example of this type of lifting equipment.

[0020] Using non-fixed point-to-point lifting equipment for fixed point-to-point installations can lead to overcapacity and poor economic efficiency. Wind turbine installation using crawler cranes falls into this category. Based on this concept, this patent designs a new type of fixed point-to-point lifting equipment, eliminating the need for overcapacity and improving installation efficiency and economic efficiency.

[0021] 2. The entire installation process requires no additional lifting equipment. Crawler crane installation of wind turbines requires other lifting and transport equipment for the transfer and installation of crawler crane components. This patented system utilizes a vehicle-mounted platform for transportation and can be independently converted from vehicle-mounted to boom-climbing installation, eliminating the need for additional lifting equipment. This fully integrated lifting system significantly reduces costs and improves efficiency.

[0022] 3. Meet installation requirements regardless of height. By alternately inserting the pins of multiple climbing sleeves and guide sliding mechanisms into the tower pin holes and lifting themselves, this patented lifting device achieves an overall step-by-step climb. As the wind turbine tower is installed, the height of this patented lifting device is increased to adapt to different installation heights, which has significant advantages for installing towers or equipment at high locations.

[0023] 4. Easy maintenance. The second boom is lifted in conjunction with the first boom and hoisted together, thus simplifying the structure of the hoisting equipment, reducing the difficulty of hoisting, and preventing the problem of a single boom being difficult to repair when damaged at high altitude. The frame adopts the method of matching two half frames of the same structure, which facilitates the standardized production of the boom.

[0024] 5. Suitable for installation of different types of tower equipment. This patented device features a retractable web rod, a docking telescopic rod in the auxiliary arm, and a sliding second latch. These three elements work together to accommodate towers of varying diameters. It is particularly suitable for self-climbing installation of tower equipment such as conical wind turbine towers or tower belt conveyors.

[0025] 6. Easy to use. The patented vehicle-mounted hoisting and climbing hoisting modes can be switched quickly and conveniently, with low requirements for roads and site locations, saving costs and construction time, and having good economic and social benefits.

[0026] 7. Versatility. In addition to being used in the installation of wind turbine towers, this patented method can also be used in the installation and maintenance of other similar tower-shaped objects. It has strong versatility and good promotion significance and market prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In the preferred solution, the first boom and the second boom can be used in combination or separately, as shown in Figure 20. When the boom is used separately, the main boom 103 is installed on both sides of the first frame 6 and the second frame 7 through the mounting seat 101.

[0062] The preferred solution also includes a crane 12, the lower end of the boom is hinged to the tail end of the crane 12, and the control method is: on-site control in the vehicle platform control room, and remote control using a wireless portable control console on site or video control in a remote control room.

[0063] Example 2:

[0064] As shown in Figure 1-19:

[0065] 1. Vehicle-mounted lifting method.

[0066] This method may seem similar to a truck crane structure, but in fact, there are substantial differences. To accommodate the two different lifting methods, the hoist 10, hydraulic system 11, slewing hanger 9 and slewing device 901, telescopic arm 8, and boom base section 3 required for lifting are optimized and integrated into this patented device.

[0067] In order to meet various lifting needs with the simplest structure, this patent designs the connection between the telescopic arm 8 at the end of the boom and the slewing hanger 9 to be a rotatable hanger. The slewing mechanism preferably adopts a combination of a slewing bearing, a ring gear and a planetary motor, or other feasible methods. This design may also cause interference between the lifting wire rope and the boom telescopic section. To solve this problem, on the one hand, we design the slewing hanger to rotate 180 degrees in a single direction and 360 degrees in both directions to ensure full-circle rotation while avoiding wire rope interference; on the other hand, we set a lifting rope hinge 15 with a suitable angle on the outermost section of the telescopic arm 8 to provide a suitable angle for the lifting rope at the hinge. Through these two special designs, it is possible to avoid the lifting wire rope from being entangled and interfering with the boom due to multiple turns of rotation. The lifting rope hinge sleeve 15 is a structure of a sleeve plus a ball hinge. The sleeve is composed of an external steel pipe and an inner lining of soft materials such as nylon. The lifting rope passes through the sleeve. The nylon lining can prevent damage to the lifting rope. The sleeve and the outermost telescopic arm 8 are connected by a ball hinge seat so that the lifting rope hinge sleeve 15 can rotate in all directions with the lifting rope.

[0068] The working process of the vehicle-mounted lifting method is to stop the vehicle-mounted platform at a suitable position according to the lifting needs, and the vehicle-mounted hydraulic station on the vehicle-mounted platform drives the slewing platform to rotate, driving the arm swing angle cylinder to rotate around the tail bracket hinge point and extend it to a suitable distance from the tail of the vehicle-mounted platform. At the same time, the hanger slewing device drives the slewing hanger to rotate to a suitable angle so that the object can be lifted.

[0069] 2. Boom climbing and hoisting method

[0070] 1. Align the vehicle-mounted platform. First, accurately reverse the hoisting transport vehicle 12 to approach the installed wind turbine tower 1301 foundation section. Using the vehicle-mounted platform, hoist the climbing hydraulic station 14 with the boom 16 to the ground near the wind turbine tower 1301 foundation section. Ensure the hydraulic lines, control lines, and electrical circuits between the climbing hydraulic station 14 and the boom 16 are properly connected. As the boom 16 rises as a whole, the hydraulic system 11 attached to the boom foundation section 3 can release the hydraulic lines, control lines, and electrical circuits in an orderly manner through the release mechanism.

[0071] 2. Climbing Cylinder Insertion Hole. Then, raise the boom 16 vertically. Adjust the position of the sliding plate seat 401 on the guide sliding mechanism 4 arranged on the boom base section 3 so that the latch 403 is aligned with the pin hole on the wind tower base section. The extended latch 403 extends into the pin hole in the wind tower base section 1301. The pin hole is preferably an elliptical hole, which has redundancy for position deviation and facilitates alignment.

[0072] 3. Assemble the climbing frame by yourself.

[0073] (1) Frame arrangement. The first boom includes a first boom, which is provided with multiple frames that can be extended and retracted in both directions along its length. There are at least two frames, with a first frame 6 and a second frame 7 arranged on the side of the first boom. The frame includes a first half frame 1, and a latch device is provided on the inner side of the first half frame 1. The latch device is used to latch the wind turbine tower 1301 of the wind turbine 13. The auxiliary arm frame 104 of the first half frame 1 and the main arm frame 103 of the second half frame 2 are socketed and matched. The main and auxiliary walls are complementary and connected to form a closed loop structure similar to a rectangle. The wind turbine tower 1301 is tightly held in the middle of the closed loop structure.

[0074] In a preferred embodiment, a first displacement sensor 109 is installed on one side of the telescopic web 108 to detect the extension and retraction length of the web cylinder 107. This sensor, in conjunction with the electro-hydraulic proportional valve in the hydraulic system, precisely controls the stopping of the web cylinder 107 when it reaches the set position. Because the tower is tapered, if the cross-sectional diameter changes, the telescopic web 108 can adjust the spacing between the main boom 103 and the auxiliary boom 104 to accommodate this change.

[0075] The preferred embodiment further includes a second boom having the same structure as the first boom. The second boom's frame includes a second half-frame 2. The first half-frame 1 and the second half-frame 2 together embrace to secure the wind turbine tower 1301. The second half-frame 2 has the same structure as the first half-frame 1, but is mounted on the second boom at a 180-degree angle. The second half-frame 2 can be interlocked with the first half-frame 1 to provide a more secure grip on the wind turbine tower 1301. The second boom can be used in conjunction with the first boom to lift the wind turbine tower 1301 without the need for a ground crane. Preferably, a two-boom 16 lifting system is installed symmetrically at the same height during the initial installation of the wind turbine tower 1301. The same-side and same-height frame arms must be arranged with a main boom 103 on one side and a secondary boom 104 on the other side to automatically dock and pin to form an effective connection. The self-docking installation is achieved through the drive of the climbing hydraulic station 14 and the hydraulic system 11.

[0076] (2) Automatic docking of the frame.

[0077] The auxiliary boom 104 is equipped with a docking telescopic rod 111, which contains a docking cylinder 110. A docking pin hole 112 is located at the end of the docking telescopic rod 111. A guide opening 115 is located at the end of the main boom 103 to facilitate the insertion of the docking telescopic rod 111. A limit baffle 113 is located within the main boom 103, which contains an in-position sensor 114. This in-position sensor 114 can be a proximity switch. When the auxiliary boom 104 abuts the limit baffle 113, a signal from the in-position sensor 114 is triggered. A locking pin cylinder 116 is located on the outside of the end of the main boom 103. This locking pin cylinder 116 is powered by a hydraulic system and has a locking pin at its end. Upon receiving the in-position signal from the in-position sensor 114, the locking pin cylinder 116 drives the locking pin into the docking pin hole 112, thereby connecting the main boom 103 and the auxiliary boom 104. When the boom 16 climbing sleeve is connected, the two boom 16 lifting systems are connected into a whole. The connecting pins between the two booms 16 and the vehicle-mounted platform are released, and the two boom 16 lifting systems are converted from the vehicle-mounted mode to the boom climbing lifting mode, and the subsequent lifting of the wind turbine tower section can begin.

[0078] 4. Hoisting by climbing method.

[0079] The wind turbine tower section that needs to be installed later is transported to the lifting range of the boom 16, and the lifting system composed of two booms 16 is controlled to drive the swing angle device 801 to change the amplitude. It can be controlled by a single action, or the double booms 16 can be controlled in linkage through the control program. After the tower section to be installed is unloaded and turned over, the hook is lifted and hoisted. During the process, the boom 16 lifting system performs actions such as boom swing angle change and extension, and hanger rotation and amplitude change to ensure that the tower section to be installed is accurately positioned.

[0080] 5. Lifting of tower sections.

[0081] In a preferred embodiment, the first latch device 105 and the second latch device 106 have similar structures. The second latch device 106 includes a latch seat 120, a tower latch 121, and a latch cylinder 122. The end of the tower latch 121 is fixedly connected to the latch seat 120. A linear sliding mechanism 117 and an adjustable telescopic cylinder 118 are provided on the inner side of the main boom 103. The movable portion of the linear sliding mechanism 117 is connected to the latch cylinder 122. The linear sliding mechanism 117 can be in the form of a slide groove, a guide rail slider, a guide rod slide, etc. The main boom 103 is pushed by the adjustable telescopic cylinder 118 to slide the second latch device 106 left and right along the main boom 103 to align with the pin hole on the wind turbine tower 1301. After alignment, the latch cylinder 122 is driven to push the latch seat 120 into the pin hole on the wind turbine tower 1301 for connection.

[0082] In the preferred solution, an adjustment telescopic cylinder 118 is further provided, one end of the adjustment telescopic cylinder 118 is fixed, and the other end of the adjustment telescopic cylinder 118 is connected to the moving part of the linear sliding mechanism 117. A second displacement sensor 119 is provided on one side of the adjustment telescopic cylinder 118, and the end of the second displacement sensor 119 is connected to the moving part of the linear sliding mechanism 117. For example, the linear sliding mechanism 117 is a guide rail slider mechanism, and the sliding platform of the guide rail slider mechanism is the moving part.

[0083] The first displacement sensor 109 and the second displacement sensor 119 can be of a wire-drawing type, a linear displacement type, or a laser type.

[0084] In the preferred scheme, the first boom includes a boom base section 3, and the side wall of the base section climbing section 302 of the boom base section 3 is provided with a guide sliding mechanism 4. The guide sliding mechanism 4 can be in the form of a slide groove with rollers or a guide rail slider, etc. Taking the slide groove with rollers as an example, multiple sliding plates with rollers are installed on the same guide rail, and a lifting cylinder 5 is provided on one side of the sliding plate. The lifting cylinder 5 preferably adopts a multi-section telescopic cylinder to increase the stroke range of the sliding plate seat 401 and provide better applicability. The two ends of the lifting cylinder 5 are respectively connected to the sliding part of the guide sliding mechanism 4 and the boom base section climbing section 302. The pushing or retraction of the lifting cylinder 5 serves as the lifting power of the sliding part of the guide sliding mechanism 4. The first boom 16 carries a hydraulic system 11 as the power source of each hydraulic actuator. When the power or hydraulic oil is insufficient, the climbing hydraulic station 14 arranged on the ground can provide power or hydraulic oil.

[0085] In the preferred embodiment, the two booms 16 are controlled synchronously and climbed as a whole. Before climbing, both booms 16 should be in the empty hook state, the booms should be adjusted to vertical, and the telescopic arms 8 should be retracted into the boom base section 3. The climbing process is as follows:

[0086] (1) Working state and initial climbing state: The first frame 6, the second frame 7, and the pin seats 120 of each guide sliding mechanism 4 are all inserted into the pin shaft holes of the wind turbine tower 1301 to ensure the stability of the entire lifting system composed of two sets of booms 16 in the working state.

[0087] (2) The first step: When the first frame 6, the second frame 7 and the guide sliding mechanisms 4 fix the wind turbine tower 1301 together, the multiple guide sliding mechanisms 4 provided in the foundation section climbing section 302 are released from the pin locks with the pin shaft holes of the wind turbine tower 1301, and the integral frame composed of the first frame 6 and the second frame 7 bears the weight of the two sets of boom 16 hoisting systems.

[0088] (3) Step 2: Next, the multiple guide slide mechanisms 4 provided in the base section climbing section 302 slide upward a climbing distance driven by the lifting cylinder 5. After aligning with the pin holes of the upper section of the wind turbine tower 1301, the pins 403 attached to the guide slide mechanisms 4 are again inserted into the pin holes of the upper section of the wind turbine tower 1301 to lock them. After being in place, the weight of the two sets of booms 16 lifting systems is taken over.

[0089] (4) Step 3: Then, the first and second sets of frames 6 and 7 are unlocked, and the lifting cylinder 5 lifts the entire boom 16 hoisting system upward for a distance, then tightly locks the wind turbine tower 1301 again, inserts the pin seat 120 into the pin shaft hole of the wind turbine tower 1301, and the first and second sets of frames 6 and 7 and the guide sliding mechanisms 4 once again bear the weight of the boom 16 hoisting system, completing the entire climbing cycle. This cycle is repeated upward to allow the first boom to climb.

[0090] 6. Lifting and boom length adjustment.

[0091] In a preferred embodiment, the first boom further comprises a telescopic arm 8, the upper end of the boom base section 3 being fixedly connected to the telescopic arm 8. The telescopic arm 8 is multi-section and retractable. A swing angle device 801 is provided in the middle of the boom base section 3. The swing angle device 801 preferably uses a motor and a speed reducer as a drive device. The speed reducer not only functions as a speed reducer but also has a swing angle limit function through a limit device, ensuring that the boom 16 rotates within a specified appropriate angle. The ring gear and the gear are engaged and meshed as a meshing force transmission device. The boom base section 3 is divided into two parts, the rear part being the base section swing angle section 301 and the front part being the base section climbing section 302. The middle part of the base section climbing section 302 is provided with a drive device for the swing angle device 801, and the rear part, the base section swing angle section 301, is provided with a meshing force transmission device for the swing angle device 801.

[0092] A first balancing cylinder 802 and a second balancing cylinder 803 are provided at the lower end of the telescopic boom 8. The ends of the first balancing cylinder 802 and the second balancing cylinder 803 are respectively hinged to the base section swing angle section 301 and the base section climbing section 302. They cooperate with the swing angle device 801 to drive the base section swing angle section 301 to swing laterally relative to the base section climbing section 302. The swing of the base section swing angle section 301 also drives the telescopic boom 8 and other devices to swing, thereby achieving luffing of the boom 16. During the luffing process, the swing angle device 801 provides the primary luffing power. Because the luffing requires a large torque and high reliability requirements, the first balancing cylinder 802 and the second balancing cylinder 803 are supplemented to provide auxiliary luffing power and ensure a smooth luffing process.

[0093] A rotatable slewing hanger 9 is provided at the upper end of the telescopic arm 8, and the slewing hanger 9 is provided with a slewing device 901. The slewing device 901 can be in the form of a large ring gear and a planetary pinion meshing. The large ring gear is fixed to the telescopic arm 8 or the slewing hanger 9, and the motor shaft end is connected to the planetary pinion, which then drives the large ring gear to rotate through the planetary pinion, thereby driving the slewing hanger 9 to rotate.

[0094] The boom 16 also includes a hoist 10 and a hydraulic system 11. The hoist 10 is used to retract and extend the hoist rope of the hook 17, driving the hook and the load at the front end of the slewing hanger 9 to rise and fall. The hydraulic system 11 provides hydraulic power to the various hydraulic components of the boom 16. Due to its small size, the hydraulic system 11 has a limited hydraulic oil reserve. When power and hydraulic oil are insufficient, they are supplemented by a climbing hydraulic station 14 located on the ground. The hydraulic system 11 and the climbing hydraulic station 14 are connected by oil pipes and control cables, and the hydraulic system 11 is equipped with a retractable device for the oil pipes and control cables.

[0095] 3. Others

[0096] 1. Troubleshooting: When climbing to a high place, if one boom fails, the other boom can help dismantle the boom or debug the fault.

[0097] 2. The preferred solution also includes a crane transport vehicle 12. The lower end of the boom 16 is hinged to the rear end of the crane transport vehicle 12. The crane transport vehicle and the boom can be separated and restored, allowing the crane system to operate both as a ground crane and in the air. Control methods include on-site control from the vehicle-mounted platform control room, remote control using a wireless portable console, or remote control via video from a remote control room.

[0098] 3. Single use of the boom. The first boom and the second boom can be used in combination or separately. If the boom is used separately, the first frame 6 and the second frame 7 both use the main boom 103 to ensure the stability of the boom 16 during the hoisting and climbing process.

[0099] In this case, the inner side refers to the side close to the wind turbine tower unless otherwise specified. Electro-hydraulic proportional control can be used when the hydraulic cylinder needs to stop at a specific position.

[0100] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
