Description

Technical Field

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

[0002] With the development of wind power projects, wind power generation has become more and more common. The installation of wind turbines usually requires the use of cranes. The structure of a traditional crane can be referred to in CN 206278849 U, a mobile crawler crane. Due to the high height of wind turbines, large crawler cranes are usually used for hoisting to meet the hoisting height, while small cranes cannot meet the requirements. However, this method also has many disadvantages: it is necessary to purchase expensive large crawler cranes, which have high requirements for road infrastructure, and it is necessary to carry out foundation treatment for the assembly and hoisting of crawler cranes and leveling the site. The disassembly, assembly and operation and maintenance of crawler cranes are also very troublesome, and the installation and disassembly of large crawler cranes also require the assistance and cooperation of small cranes. Therefore, a more convenient vehicle-mounted hoisting platform than a large crawler crane is needed, which can be used as an ordinary crane usually. When installing the wind turbine tower, it can complete all hoisting work independently without the assistance of other cranes, and should have a self-climbing function, so as to meet the installation requirements of higher parts of the tower and equipment as the tower is installed and raised, thus simplifying the structure.

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

[0004] The present invention provides a boom system for the autonomous installation of fans and large construction equipment, which solves the problem that it is difficult to install the wind turbines and large construction equipment towers located at high places.

[0010] In a preferred embodiment, a limit baffle is provided inside the main boom. A position sensor is provided in the limit baffle. The position sensor is used to detect the docking telescopic rod of the auxiliary boom.

[0011] In a preferred embodiment, the second pin device includes a pin seat, a tower barrel pin and a pin oil cylinder. The structure is the same as that of the first pin device. The pin oil cylinder is responsible for performing telescopic movement. The tower barrel pin is inserted into the tower barrel. The pin seat bears the force. The end of the tower barrel pin is connected to the pin oil cylinder. The pin seat is slidably sleeved with the tower barrel pin. A linear sliding mechanism is provided inside the main boom. The moving part of the linear sliding mechanism is connected to the pin oil cylinder.

[0012] In a preferred embodiment, the first boom includes a boom base section. The boom base section includes a base section swing angle section and a base section climbing section.

[0014] In a preferred embodiment, a hoisting vehicle is further included. The lower end of the boom is hinged to the rear end of the hoisting vehicle.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. Avoiding functional redundancy and having high economy.

[0017] (1) Wind turbine installation method. Compared with other lifting construction methods, the significant feature of wind turbine installation is that the relationship between the lifting point and the drop point is simple and fixed. Specifically, wind turbine installation is generally lifted from the ground in front of the tower, and the hook is dropped on the top of the tower for step-by-step installation. 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.

[0018] (2) Other lifting construction methods. This is a lifting method in which the lifting point and the drop point are frequently changed within the working range of the crane, that is, the lifting point and the drop point are not fixed, which is a non-fixed point-to-point lifting method. This lifting method has high requirements for the amplitude of the lifting equipment, which leads to a complex crane structure and high price. Crawler cranes belong to this type of lifting equipment.

[0019] If non-fixed point-to-point lifting equipment is used for fixed point-to-point lifting work, there will be problems of redundant lifting equipment performance and poor economy. The use of crawler cranes to install wind turbines belongs to this category. Based on this idea, this patent designs a new type of fixed point-to-point lifting equipment, thereby avoiding redundant lifting equipment functions and improving installation efficiency and economy.

[0020] 2. The entire installation process does not require the assistance of other lifting equipment. The crawler crane installation method requires other lifting and transportation equipment to transport and install crawler crane components. This patent uses a vehicle-mounted platform for transportation, and can also independently convert the vehicle-mounted lifting method to the boom climbing lifting method without the need for other lifting equipment, realizing the full process integration of the lifting equipment, greatly saving costs and improving efficiency.

[0021] 3. Meet the requirements of installation without height restrictions. Through the pins of multiple climbing sleeves and guide sliding mechanisms alternately inserted into the tower pin holes and jacking themselves up, the overall step-by-step climbing of this patented lifting equipment is achieved. With the installation of the wind turbine tower, the height of this patented lifting equipment is increased to adapt to different installation heights, which has significant advantages for towers or equipment installed at high places.

[0022] 4. Easy maintenance. The second boom and the first boom are jointly climbed and lifted to simplify the structure of the lifting equipment, reduce the difficulty of lifting, and prevent the problem of a single boom being difficult to repair when damaged at high altitude; the frame adopts the method of two half frames of the same structure to facilitate the standardized production of the boom.

[0023] 5. Suitable for installation of different types of tower equipment. This patent is equipped with a retractable belly rod device, a docking telescopic rod in the auxiliary arm frame, and a second sliding pin device. The three are used together to adapt to towers of different diameters. It is particularly suitable for the self-climbing installation of tower equipment such as conical wind turbine towers or tower belt machines.

[0024] 6. Easy to use. The conversion between the vehicle-mounted hoisting and the climbing hoisting in this patent is rapid and convenient, with low requirements for roads and on-site venues, saving costs and construction periods, and having good economic and social benefits.

[0025] 7. Versatility. In addition to being used in the installation of wind turbine towers, this patent can also be used in the installation and maintenance of other similar tower-shaped objects, with strong versatility, good promotion significance and market prospects.

[0061] In a preferred embodiment, a hoisting vehicle 12 is further included. The lower end of the lifting arm is hinged to the tail end of the hoisting vehicle 12. The control modes are: a local control mode in the on-vehicle platform control room, and a remote control mode of wireless portable console control or remote control room video control on site.

[0062] Embodiment 2:

[0063] As Figure 1-19 follows:

[0064] I. Vehicle-mounted hoisting method.

[0065] This method seems similar to the structure of a truck crane, but in fact, there are substantial and significant differences. To adapt to the two different hoisting methods, the winch 10, hydraulic system 11, slewing hanger 9, slewing device 901, telescopic boom 8, boom base section 3, etc. required for hoisting are all optimized and integrated on the equipment of this patent.

[0066] In order to meet various diverse hoisting requirements with the simplest structure, the connection method between the outermost telescopic boom 8 of the boom and the slewing hanger 9 in this patent is designed as a way that the hanger can slewing. The slewing mechanism preferably adopts a combination of a slewing bearing, a gear ring and a planetary motor, or other feasible ways. This design may also cause interference between the lifting wire rope and the boom telescopic section. To solve this problem, on the one hand, the slewing of the slewing hanger is designed to be 180 degrees in a single direction and 360 degrees in both left and right directions, avoiding wire rope interference while ensuring full-circle slewing; on the other hand, a lifting rope hinge sleeve 15 at a suitable angle is provided on the outermost telescopic boom 8 to provide a suitable folding angle for the lifting rope at the hinge sleeve. Through these two special designs, it is possible to avoid the lifting wire rope from winding and interfering on the boom due to multi-turn slewing. The lifting rope hinge sleeve 15 is a structure of a sleeve plus a spherical hinge. The sleeve consists of an external steel pipe plus a lining of soft materials such as nylon. The lifting rope passes through the sleeve, and the nylon lining can prevent damage to the lifting rope. The sleeve is connected to the outermost telescopic boom 8 by a spherical hinge seat so that the lifting rope hinge sleeve 15 can rotate in all directions along with the lifting rope.

[0067] The working process of the vehicle-mounted hoisting method is to stop the vehicle-mounted platform at a suitable position according to the hoisting needs, drive the slewing platform to rotate by the vehicle-mounted hydraulic station on the vehicle-mounted platform, drive the boom swing angle cylinder to rotate around the hinge point of the tail bracket, extend a suitable distance from the tail of the vehicle-mounted platform, and at the same time, the slewing device of the hanger drives the slewing hanger to rotate to a suitable angle so as to be able to lift an object.

[0068] II. Boom climbing hoisting method

[0069] 1. Alignment of the vehicle-mounted platform. First, accurately reverse the hoisting transport vehicle 12 to approach the foundation section of the already installed wind turbine tower 1301. Under the vehicle-mounted working condition, hoist the climbing hydraulic station 14 to the ground near the foundation section of the wind turbine tower 1301 with the boom 16, and make good connections of the hydraulic pipelines, control and electrical circuits between the climbing hydraulic station 14 and the boom 16. As the boom 16 climbs as a whole, the hydraulic pipeline and control and electrical circuits can be orderly released through the release mechanism in the hydraulic system 11 box attached to the boom base section 3.

[0070] 2. Hoisting cylinder access hole. Then, vertically erect the boom 16, and adjust the position of the sliding plate seat 401 on the guiding sliding mechanism 4 arranged on the boom base section 3 so that the pin 403 aligns with the pin hole on the wind turbine tower base section. The extended pin 403 extends into the pin hole of the wind turbine tower 1301 base section. The pin hole preferably adopts the form of an oval hole, which has a redundancy for position deviation to facilitate alignment and insertion into the hole.

[0071] 3. Self-assembly of the climbing sleeve frame.

[0072] (1) Arrangement of the sleeve frame. It includes a first boom. The first boom is provided with a plurality of telescopable sleeve frames that can expand and contract on both sides along the length direction. There are at least two sleeve frames. The first sleeve frame 6 and the second sleeve frame 7 are arranged on the side of the first boom. The sleeve frame includes a first half-sleeve frame 1. The inner side of the first half-sleeve frame 1 is provided with a pinning device, which is used to pin the wind turbine tower 1301 of the wind turbine 13. The auxiliary boom 104 of the first half-sleeve frame 1 and the main boom 103 of the second half-sleeve frame 2 are sleeved and matched. After the main and auxiliary booms are complementarily connected, a closed-loop structure similar to a rectangle is formed, and the wind turbine tower 1301 is held tightly in the middle of the closed-loop structure.

[0073] In a preferred solution, a first displacement sensor 109 is provided on one side of the telescopic web member 108, which is used to detect the telescopic length of the web member cylinder 107, and cooperate with the electro-hydraulic proportional valve in the hydraulic system to accurately control the stop of the web member cylinder 107 when the web member cylinder 107 extends to the set position. Since the tower is conical and the cross-sectional diameter changes, the telescopic web member 108 can adjust the distance between the main boom 103 and the auxiliary boom 104 to adapt to this change.

[0074] In a preferred solution, it further includes a second boom. The second boom has the same structure as the first boom. The sleeve frame of the second boom includes a second half-sleeve frame 2. The first half-sleeve frame 1 and the second half-sleeve frame 2 are clasped to fix the wind turbine tower 1301. The structure of the second half-sleeve frame 2 is the same as that of the first half-sleeve frame 1, but the angle is 180 degrees different and it is installed on the second boom. The second half-sleeve frame 2 can be sleeved and matched with the first half-sleeve frame 1 to make the clamping of the wind turbine tower 1301 more stable; the second boom can be used in combination with the first boom to hoist the wind turbine tower 1301 without the cooperation of a ground crane. It is preferably to install two boom 16 hoisting systems symmetrically at the same height on the left and right of the initial installation section of the wind turbine tower 1301. The sleeve frame arm rods on the same side and at the same height need to be arranged in the way of one main boom 103 and one auxiliary boom 104 on one side, so as to automatically butt and insert pins to form an effective connection, and realize self-butt and installation through the drive of the climbing hydraulic station 14 and the hydraulic system 11.

[0075] (2) Automatic docking of the sleeve frame.

[0076] The auxiliary boom 104 is provided with a docking telescopic rod 111. A docking oil cylinder 110 is arranged inside the docking telescopic rod 111. A docking pin hole 112 is provided at the end of the docking telescopic rod 111. A guiding opening 115 is provided at the end of the main boom 103 to facilitate the guiding insertion of the docking telescopic rod 111. A limiting baffle 113 is arranged inside the main boom 103. A position sensor 114 is arranged in the limiting baffle 113. The position sensor 114 can be a proximity switch. When detecting that the auxiliary boom 104 abuts against the limiting baffle 113, the in-place signal of the position sensor 114 is triggered. A locking pin oil cylinder 116 is arranged outside the end of the main boom 103. The locking pin oil cylinder 116 is powered by a hydraulic system. A locking pin is arranged at the end of the locking pin oil cylinder 116. After receiving the in-place signal of the position sensor 114, the locking pin oil cylinder 116 drives the locking pin to insert into the docking pin hole 112 to connect the main boom 103 and the auxiliary boom 104. When the climbing sleeve frames of the two booms 16 are connected, the two boom 16 hoisting systems are connected into a whole. By unlocking the connection pins of the two booms 16 and the vehicle-mounted platform, the two boom 16 hoisting systems realize the conversion from the vehicle-mounted mode to the boom climbing hoisting mode, and the subsequent hoisting of the wind turbine tower section can be started.

[0077] 4. Hoisting in the climbing mode.

[0078] Transport the subsequent wind turbine tower sections to be installed within the hoisting amplitude range of the boom 16. Control the hoisting system composed of the two booms 16 to drive the swing angle device 801 to perform amplitude variation. It can be controlled single-acting or, through the control program, the two booms 16 can be controlled in a coordinated manner. After unloading and turning over the tower section to be installed, hook up and lift it for hoisting. During the process, the hoisting system of the boom 16 performs actions such as swing angle variation, telescoping, and slewing of the hanger to ensure the accurate positioning of the tower section to be installed.

[0079] 5. Tower section jacking.

[0080] In a preferred solution, the structures of the first pin device 105 and the second pin device 106 are similar. The second pin device 106 includes a pin seat 120, a tower barrel pin 121, and a pin oil cylinder 122. The end of the tower barrel pin 121 is fixedly sleeved with the pin seat 120. A linear sliding mechanism 117 and an adjusting telescopic oil cylinder 118 are arranged inside the main boom 103. The moving part of the linear sliding mechanism 117 is connected to the pin oil cylinder 122. The linear sliding mechanism 117 can be in the form of a chute, a guide rail slider, a guide rod sliding seat, etc. The main boom 103 is pushed by the adjusting telescopic oil cylinder 118 to slide the second pin device 106 left and right along the main boom 103 to align with the pin hole on the wind turbine tower barrel 1301. After alignment, by driving the pin oil cylinder 122, the pin seat 120 is pushed into the pin hole on the wind turbine tower barrel 1301 for connection.

[0081] In a preferred solution, an adjusting telescopic oil cylinder 118 is further provided. One end of the adjusting telescopic oil cylinder 118 is fixed, and the other end of the adjusting telescopic oil 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 adjusting telescopic oil 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 table of the guide rail slider mechanism is the moving part.

[0082] The first displacement sensor 109 and the second displacement sensor 119 can adopt the form of wire drawing type, linear displacement type or laser type, etc.

[0083] In a preferred solution, the first boom includes a boom base section 3. A guiding sliding mechanism 4 is provided on the side wall of the base section climbing section 302 of the boom base section 3. The guiding sliding mechanism 4 can adopt the form of a chute with rollers or a guide rail slider, etc. Taking the form of a chute with rollers as an example, a plurality of sliding plates with rollers are installed on the same guide rail. A jacking oil cylinder 5 is provided on one side of the sliding plate. The jacking oil cylinder 5 preferably adopts a multi-stage telescopic oil cylinder to increase the stroke range of the sliding plate seat 401 and provide better applicability. Both ends of the jacking oil cylinder 5 are respectively connected to the sliding part of the guiding sliding mechanism 4 and the base section climbing section 302 of the boom base section. The pushing or retracting of the jacking oil cylinder 5 serves as the lifting power for the sliding part of the guiding sliding mechanism 4. The first boom 16 carries the hydraulic system 11 as the power source for 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.

[0084] In a preferred solution, the two booms 16 are climbed in a synchronous control and integral manner. Before climbing, both of the two booms 16 should be in the state of empty hook, the boom should be adjusted to be vertical, and the telescopic booms 8 should be retracted into the boom base section 3. The climbing process is as follows:

[0085] (1) Working state and initial climbing state: The pins of the first set of frames 6 and the second set of frames 7 and the pin sockets 120 of each guiding sliding mechanism 4 are inserted into the pin holes of the wind turbine tower barrel 1301 to ensure the stability of the entire hoisting system composed of the two booms 16 in the working state.

[0086] (2) The first step: In the state where the first set of frames 6, the second set of frames 7 and each guiding sliding mechanism 4 fix the wind turbine tower barrel 1301 together, the multiple guiding sliding mechanisms 4 provided in the base section climbing section 302 loosen the pin locking with the pin holes of the wind turbine tower barrel 1301, and the overall set of frames composed of the first set of frames 6 and the second set of frames 7 bears the weight of the hoisting system of the two booms 16.

[0087] (3) Second step: Next, the multiple guiding and sliding mechanisms 4 provided in the base section climbing section 302 slide upward by a distance of one climbing stroke under the drive of the jacking cylinder 5. After aligning with the pin holes of the upper section of the wind turbine tower barrel 1301, the pins 403 attached to the guiding and sliding mechanisms 4 are inserted into the pin holes of the upper section of the wind turbine tower barrel 1301 again for locking. After being in place, the weight of the two sets of jib 16 hoisting systems is taken over.

[0088] (4) Third step: Then, the first set of frames 6 and the second set of frames 7 are unlocked. The jacking cylinder 5 jacks up the entire jib 16 hoisting system upward by a certain distance, and then clamps and locks the wind turbine tower barrel 1301 again. The pin seat 120 is inserted into the pin hole of the wind turbine tower barrel 1301. The first set of frames 6, the second set of frames 7, and each guiding and sliding mechanism 4 bear the weight of the jib 16 hoisting system together again, and the entire climbing cycle is completed. By repeating this cycle and climbing upward, the first jib climbs.

[0089] 6. Hoisting and luffing.

[0090] In a preferred solution, the first jib further includes a telescopic boom 8. The upper end of the jib base section 3 is fixedly connected to the telescopic boom 8. The telescopic boom 8 is multi-section and telescopic. A swing angle device 801 is provided in the middle of the jib base section 3. The swing angle device 801 preferably uses a motor and a speed reduction and limit device as the driving device. The speed reduction and limit device not only has the function of a speed reducer, but also has a swing angle limiting function through the limiting device to ensure that the jib 16 rotates within a limited and appropriate angle. The gear ring is sleeved and meshed with the gear as the meshing force transmission device. The jib base section 3 is divided into front and rear pieces. The rear piece is the base section swing angle section 301, and the front piece is the base section climbing section 302. The driving device of the swing angle device 801 is provided in the middle of the base section climbing section 302, and the meshing force transmission device of the swing angle device 801 is provided in the rear piece base section swing angle section 301.

[0091] The lower end of the telescopic boom 8 is provided with a first balance cylinder 802 and a second balance cylinder 803. The two ends of the first balance cylinder 802 and the second balance cylinder 803 are respectively hinged to the base section swing angle section 301 and the base section climbing section 302, and cooperate with the swing angle device 801 to drive together, realizing the lateral swing of the base section swing angle section 301 relative to the base section climbing section 302. When the base section swing angle section 301 swings, it also drives devices such as the telescopic boom 8 to swing, thereby realizing the luffing of the jib 16. During the luffing process, the swing angle device 801 provides the main luffing power. Because the torque required for luffing is large and the reliability requirement is high, the first balance cylinder 802 and the second balance cylinder 803 are supplemented to provide auxiliary luffing power and ensure the smoothness of the luffing process.

[0092] At the upper end of the telescopic arm 8, there is a rotatable slewing hanger 9. The slewing hanger 9 is provided with a slewing device 901. The slewing device 901 can adopt forms such as the meshing of a large gear ring and a planetary pinion. The large gear ring is fixed to the telescopic arm 8 or the slewing hanger 9. The end of the motor shaft is connected to the planetary pinion, and then the large gear ring is driven to rotate by the planetary pinion, driving the slewing hanger 9 to rotate.

[0093] The boom 16 is also equipped with a winch 10 and a hydraulic system 11. The winch 10 is used to wind and unwind the lifting rope of the hook 17, driving the hook and the lifted object at the front end of the slewing hanger 9 to rise and fall. The hydraulic system 11 is used to provide hydraulic power for each hydraulic component of the boom 16. Due to its small size and limited hydraulic oil storage, when the power and hydraulic oil are insufficient, the climbing hydraulic station 14 set on the ground provides supplementary power and hydraulic oil. The hydraulic system 11 is connected to the climbing hydraulic station 14 through oil pipes and control cables. The hydraulic system 11 is provided with a retracting and deploying device for the oil pipes and control cables.

[0094] III. Others

[0095] 1. Fault handling. When climbing to a high place, if a certain boom fails, the other boom can assist in disassembling the boom or debugging the fault.

[0096] 2. In a preferred solution, it also includes a lifting vehicle 12. The lower end of the boom 16 is hinged to the rear end of the lifting transport vehicle 12. The lifting vehicle 12 and the boom 16 can be disassembled and restored, so that this lifting system can work as a ground crane and can also climb into the air to work. The control methods are: the on-site control method in the vehicle-mounted platform control room, and the remote control method of using a wireless portable console on-site or video control in the remote control room.

[0097] 3. Independent use of the boom. The first boom and the second boom can be used either in combination or independently. If the boom is used independently, then the first mounting frame 6 and the second mounting frame 7 both use the main boom 103 at this time to ensure the stability of the boom 16 during the lifting and climbing processes.

[0098] In this case, the inner side refers to the side close to the wind turbine tower without special instructions. Electro-hydraulic proportional control can be adopted for the situation where the hydraulic cylinder needs to stop at a specific position.

[0099] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
