Description

Technical Field

[0001] The invention relates to the technical field of segment beam lifting and handling equipment, and in particular to a hoisting device, a hoisting system and a hoisting method suitable for hoisting tower column segments. Background Art

[0002] If the cable towers of large suspension bridges and cable-stayed bridges are designed with steel structures or steel-concrete structures, the common installation and construction method is generally to divide the steel towers into several segments horizontally and vertically, and then use a large tower crane attached to the side of the cable tower with a special hoist to lift and transfer these steel tower segments from the transport ship to the designed position of the cable tower for installation. Since the design of each bridge cable tower is different, the cable tower can be presented as a vertical and inclined structure, and the cross section of the cable tower gradually decreases from the bottom to the top. Sometimes both the transverse and longitudinal directions are gradual structures. The above structural forms put forward several requirements for the special hoisting hoist and the hoisting construction method. First, the hoisting structure needs to adapt to the continuous changes in the lifting points of each steel tower segment. When the positions of the lifting points in both the transverse and longitudinal directions change, the hoist must have the function of adjusting the lifting points. Second, the hoist must have the function of adjusting the aerial posture of the steel tower segment. Third, the entire hoisting process needs to be convenient, fast, safe and reliable, while reducing the output of manpower, material resources and construction time.

[0003] The current status of special lifting equipment and lifting operation methods are as follows:

[0004] 1. The lifting points of most special slings are set to be fixed, that is, multiple fixed lifting points are set on the sling according to the specific positions of the lifting points of the steel tower segments of each project. If there are many lifting segments, the number of fixed lifting points set on the sling will increase. If the positions of the lifting points in both directions change, the structure of the sling will become very complicated. At the same time, since the lifting points are fixed, if the lifting point connection method adopts the pin type, it is possible that the lifting ears on the sling and the lifting ears on the steel tower segments cannot be assembled due to manufacturing deviations;

[0005] 2. Although some slings have adjustable lifting points, they are usually moved manually, which is inefficient and the moving position may not be accurate enough. Especially when the pin connection is adopted, the position of the lifting point on the sling needs to be adjusted manually to adapt to the position of the lifting lug.

[0006] 3. Existing hoists cannot adjust the aerial posture of steel tower segments. Some hoists are only equipped with adjustment mechanisms in a certain direction to adapt to the installation of inclined towers, and are not adaptable to complex working conditions. Especially when the center of gravity of the steel tower segment and the center of the tower crane hoisting mechanism do not coincide, the steel tower segment cannot maintain a horizontal posture during the hoisting process. In order to facilitate installation, a large amount of manual pulling is used when the segment posture needs to be adjusted, which is time-consuming and laborious.

[0007] 4. During the hoisting process, the crane driver controls the movement of the hoist in all directions. Due to the long distance, the ground personnel need to communicate with the driver's room in real time through walkie-talkies to guide the hoisting, which makes communication and coordination inconvenient and inefficient.

[0008] In view of the above construction status, a new type of lifting device mechanism and advanced control method are urgently needed to improve the adaptability and construction efficiency of steel tower segment lifting. Summary of the invention

[0081] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0082] The present application relates to a sling suitable for hoisting tower column segments. The sling of the present application is a flexible sling with multiple degrees of freedom, which can be used for hoisting tower column segments of different structures and can be adaptively adjusted according to the hoisting points on the tower column segments. Figures 1 to 8 As shown, the sling of the present application includes a suspension beam 1, a slewing support beam 2, a main beam 3, a distribution beam 4 and a rotary lock pull rod 5. The suspension beam 1 is a beam structure fixedly connected to the tower motor pulley block, such as Figure 1 As shown, the suspension beam 1 is an I-shaped box structure, which is welded into a whole by a number of high-strength alloy steel plates. The upper part of the suspension beam 1 is connected to two movable pulley blocks 6 of the tower crane through two pin shafts.

[0083] Four sets of hydraulic adjustment structures are arranged below the suspension beam 1, and the upper ends of the four sets of hydraulic adjustment structures are respectively fixed to the four corners of the suspension beam 1, and are used to adjust the inclination angles in the X and Y directions and the height in the Z direction of the suspended object. During the adjustment process, one or more sets of hydraulic adjustment structures corresponding to the four sets of hydraulic adjustment structures are adjusted, that is, the inclination angle in the X or Y direction can be adjusted, and the height in the Z direction can be adjusted by synchronously driving the four sets of hydraulic adjustment structures.

[0084] The slewing support beam 2 is a tic-tac-toe structure, with the main force-bearing structures on both sides being box beam structures, and the middle is connected by an I-beam. The slewing support beam 2 is equipped with a slewing structure, which is used to drive the suspended object to rotate around the Z axis. The middle position of the main beam 3 is connected to the slewing structure. In fact, it is the slewing structure that drives the main beam 3 to rotate around the Z axis, so as to adjust the rotation angle of the suspended object.

[0085] The distribution beam 4 of the present application has two groups, and the two groups of distribution beams 4 are placed at both ends of the main beam 3. The distribution beam 4 is a box-shaped structural beam, and the distribution beam 4 is connected to the end of the main beam 3, and can be moved along the length direction of the main beam 3 and rotated around the vertical axis. Specifically, the present application installs a first translation structure and a rotation structure on the distribution beam 4, the first translation structure is used to drive the distribution beam 4 to move along the length direction of the main beam 3, and the rotation structure is used to drive the distribution beam 4 to rotate around the Z axis.

[0086] Two rotary lock rods 5 are installed on each group of distribution beams 4. The rotary lock rods 5 are rod-shaped structures with rotary lock heads at the lower end. The rotary lock heads are inserted into the lock buckle of the lifting ear of the suspended object. The rotary lock heads are rotated at a set angle to connect the rotary lock heads with the lock buckle in the vertical direction. After the suspended object is installed in place, the rotary lock heads are rotated at a set angle again, and the rotary lock heads can be vertically drawn out from the lock buckle. The two rotary lock rods 5 on the same group of distribution beams 4 are placed at both ends of the distribution beam 4.

[0087] A second translation structure is provided between the distribution beam 4 and the rotary lock rod 5, which is used to drive the rotary lock rod 5 to move along the length direction of the distribution beam 4. The first translation structure, the second translation structure and the rotation structure are used to adjust the position of the rotary lock rod 5 so that the rotary lock rod 5 corresponds to the lifting lug on the object being hoisted. The first translation structure and the second translation structure are used to adjust the rotary lock rod 5 in a linear direction, and the rotation structure is used to adjust the rotary lock rod 5 in an arc direction.

[0088] The present application also installs a twist lock structure on the distribution beam 4, and the twist lock structure is used to drive the twist lock rod 5 to rotate a set angle around the vertical axis, so as to achieve automatic locking or unhooking of the twist lock rod 5.

[0089] When in use, the tower crane driver operates the hoist to move the hoist to the hoisted object. After obtaining the position of the hoisting ear of the hoisted object, the operator operates the hoist to adjust the position of the rotary lock rod 5. The first translation structure, the second translation structure, and the rotation structure adjust the position of the rotary lock rod 5 to align the rotary lock rod 5 with the position of the hoisting ear of the hoisted object. The four groups of hydraulic adjustment structures lower the rotary lock rod so that the lower end of the rotary lock rod 5 extends into the lock buckle of the hoisting ear of the hoisted object. The rotary lock structure drives the rotary lock rod 5 to rotate a set angle (the set angle of this application is 90°), and the rotary lock rod 5 is locked with the hoisting ear. The four sets of hydraulic positioning structures synchronously lift the suspended object up, observe the aerial posture of the suspended object, and adjust the posture of the suspended object through the four sets of hydraulic positioning structures and the rotary structure until the set requirements are met. The tower crane driver operates the hoisting device together with the suspended object to the installation position. After the requirements are met, the four sets of hydraulic positioning structures are synchronously lowered, and the suspended object gradually falls into the installed segment guide mechanism until the suspended object is completely lowered and fixed. The rotary lock structure drives the rotary lock pull rod 5 to rotate and unhook, and the four sets of hydraulic positioning structures lift the hoisting device as a whole to complete the hoisting process of a tower column segment.

[0090] In some embodiments of the present application, the present embodiment optimizes the above-mentioned hydraulic adjustment structure, specifically as follows: Figure 3 As shown, the hydraulic positioning structure of this embodiment includes a hydraulic jack 101, a lifting steel strand 102 and a steel strand anchor 103. The hydraulic jack 101 is a continuous lifting jack that can be vertically extended and retracted. The upper end of the hydraulic jack 101 is connected to the suspension beam 1 through a pin. The upper end of the lifting steel strand 102 is fixedly connected to the lower end of the hydraulic jack 101. The steel strand anchor 103 is fixedly connected to the lower end of the lifting steel strand 102, and the steel strand anchor 103 is fixedly connected to the slewing support beam 2 through a pin.

[0091] Four groups of hydraulic jacks 101 are placed at the four corners of the suspension beam 1 to form a four-hanging point structure. Synchronously adjusting the two groups of hydraulic jacks 101 on the same side of the suspension beam 1 can adjust the inclination angle in that direction. For example, synchronously adjusting the two groups of hydraulic jacks 101 on the X side can adjust the inclination angle of the suspended object in the X direction.

[0092] In some other embodiments of the present application, the present embodiment optimizes the above-mentioned rotary structure, specifically as follows Figure 4As shown, the rotary structure includes a rotary bearing 201 and a rotary motor 202. The inner ring of the rotary bearing 201 is fixed to the lower end surface of the rotary support beam 2, and the outer ring of the rotary bearing 201 is fixed to the main beam 3. The main beam 3 can generate relative displacement with the rotary support beam 2 around the axis (Z axis) of the rotary bearing 201 through the rotary bearing 201. Screw holes are reserved on the rotary support beam 2 and the main beam 3, and the rotary bearing 201 can be fixed to the rotary support beam 2 and the main beam 3 through the bolt structure. The rotary motor 202 is installed on the rotary support beam 2, and the rotary motor 202 is connected to the outer ring of the rotary bearing 201 through the rotary gear 203.

[0093] The slewing structure is used to adjust the rotation angle of the suspended object around the Z direction. When the rotation angle of the heavy object around the Z direction needs to be adjusted, the outer ring of the slewing bearing 201 is driven to rotate by the slewing motor 202, and the main beam 3 rotates along with the outer ring of the slewing bearing 201, so that the rotation angle of the suspended object around the Z direction can be adjusted.

[0094] In some embodiments of the present application, the first translation structure is optimized. Figures 5-6 As shown, the first translation structure of this embodiment includes an adjustment slide 301 and a first electric push rod 304. Slide grooves 303 extending along the length direction of the main beam 3 are provided on both sides of the main beam 3. Two side rods extending vertically are provided on the adjustment slide 301, and the side rods are disposed on both sides of the main beam 3. Slide shoes 302 are installed on the side rods. The two side rods and two groups of slide shoes 302 are clamped on both sides of the main beam 3, and the slide shoes 302 are slidably connected in the slide grooves 303 on both sides of the main beam 3. One end of the first electric push rod 304 is fixed on the main beam 3, and the other end is connected to the adjustment slide 301, which is used to drive the adjustment slide 301 to move along the slide groove 303.

[0095] When adjusting the position of the rotary lock pull rod 5 , the first electric push rod 304 can be used to drive the adjustment slide 301 to slide in the slide groove 303 to change the position of the distribution beam 4 along the length direction of the main beam 3 .

[0096] In a further embodiment of the present application, the present embodiment further optimizes the above-mentioned rotation structure. Specifically, Figure 6 As shown, the rotating structure includes a rotating bearing 305 and a rotating motor 306. The inner ring of the rotating bearing 305 is fixed to the lower end of the adjusting slide 301, and the outer ring of the rotating bearing 305 is fixedly connected to the distribution beam 4 below. The rotating motor 306 is installed on the adjusting slide 301 and is connected to the outer ring of the rotating bearing 305 through a rotating gear 307.

[0097] The rotating structure is used to drive the distribution beam 4 to rotate around the vertical axis. When adjusting the position of the rotary lock rod 5, in some cases, the linear adjustment can no longer make the rotary lock rod 5 adapt to the position of the lifting lug, and the rotating structure is required to adjust the rotary lock rod 5. By driving the rotary motor 306, the rotary motor 306 drives the outer ring of the rotary bearing 305 to rotate through the rotary gear 307, and the distribution beam 4 rotates with the outer ring of the rotary bearing 305, thereby reaching the desired adjustment position.

[0098] In some other embodiments of the present application, the second translation structure is optimized. Figure 7 As shown, the second translation structure of this embodiment includes a support slide 401 and a second electric push rod 403. The second translation structure is similar to the first translation structure, and its purpose is to adjust the position of the rotary lock rod 5 in a straight line. Unlike the first translation structure, the second translation structure is used to adjust the position of the rotary lock rod 5 along the length direction of the distribution beam 4. In this embodiment, slideways 402 arranged along the length direction of the distribution beam 4 are provided at both ends of the distribution beam 4. The support slide 401 is slidably connected in the slideway 402, and the support slide 401 is fixedly connected to the distribution beam 4 except in the length direction of the distribution beam 4. One end of the second electric push rod 403 is fixed to the distribution beam 4, and the other end is connected to the support slide 401, which is used to drive the support slide 401 to move along the length direction of the distribution beam 4.

[0114] The first controller sends a command to the rotary lock motor 503, and the rotary lock motor 503 drives the rotary lock pull rod 5 to rotate 90 degrees, and the rotary lock head and the lock buckle are locked;

[0115] S4, the first controller sends a command to the four groups of hydraulic jacks 101, and the four groups of hydraulic jacks 101 lift the sling and the suspended object as a whole. After the sling and the suspended object are lifted 2 meters off the ground, the control posture of the suspended object is observed, and the posture of the suspended object in the three directions of X, Y and Z is checked through the display screen. At the same time, the simulated position of the center of gravity of the suspended object is checked, and the posture of the suspended object is adjusted according to the angle deviation displayed on the display screen;

[0116] Specifically, instructions are sent to the four groups of hydraulic jacks 101 and the rotary motor 202 to adjust the aerial posture of the suspended object;

[0117] S5. After the posture adjustment is completed, the tower crane driver moves the spreader and the suspended object to the installation position, controls the four sets of hydraulic adjustment structures to lower the suspended object to the installation position and fix it, controls the rotary lock motor 503 to unhook the rotary lock rod 5, and the four sets of hydraulic jacks 101 lift the spreader as a whole, and the rotary lock rod 5 is completely separated from the suspended object, completing a lifting process.
