Description

Technical Field

[0001] The present invention relates to the field of segmental beam lifting and handling equipment. More specifically, the present invention relates to a segmental beam spreader with a connecting rod opening and closing type modular longitudinal movement mechanism and a construction method thereof. Background Art

[0002] In the precast and assembled construction of concrete segmental beams, the segmental beams need to be hoisted repeatedly, and the distribution of the lifting holes of the segmental beams is greatly different due to various factors. The spreaders generally used for traditional segmental beam hoisting are spreaders with manually driven sliding suspension rods. The suspension rods generally adopt a structural form with end anchor fittings installed at the ends of fine rolled threaded steel bars. The completion of one hoisting of a segmental beam generally requires the following processes: First, construction workers need to manually adjust the distance between the suspension rods to adapt to the distance between the lifting holes of the segmental beam; Second, construction workers need to stand on the top surface of the segmental beam to be hoisted and push the segmental beam spreader to assist the suspension rods to enter the lifting holes; Third, construction workers need to enter the inner cavity of the segmental beam to install the end anchor fittings and wedge-shaped pads of the fine rolled threaded steel bars to form a stable stress surface; Fourth, the hoisting equipment hoists the segmental beam to the designated position; Fifth, construction workers need to enter the inner cavity of the segmental beam again to disassemble the end anchor fittings and wedge-shaped pads of the fine rolled threaded steel bars to ensure that the suspension rods can be smoothly removed from the lifting holes; Sixth, the hoisting equipment lifts the segmental beam spreader to a certain height, and one hoisting operation of the segmental beam is completed.

[0003] Traditional segmental beam hoisting generally adopts a four-suspension rod spreader, that is, four-point hoisting. According to the principle that three points determine a plane, four-point hoisting has only one statically indeterminate problem. If appropriate pre-tightening force is added to the suspension rods or the distribution beam method is adopted before segmental beam hoisting, the "virtual rod" phenomenon caused by the deformation of the segmental beam spreader and the segmental beam body can be avoided. Therefore, four-point hoisting has good force uniformity and stability and is widely used. However, for segmental beams with a large tonnage and a long and wide width, when four-point hoisting is adopted, the local load of each stress point is large and the support stiffness is small. When hoisting, it will cause a large deflection of the segmental beam, and it is easy to cause varying degrees of damage to the structure of the segmental beam body during the hoisting process.

[0004] Traditional segmental beams need to go through multiple transfers and stacks from the precast beam yard to the construction site and then to the installation position of the designated segment. That is to say, the segmental beams need to experience repeated hoisting during the process from production to use. There are problems such as cumbersome hoisting operation process, large number of construction workers required, long hoisting cycle, damage to large-tonnage hoisting, and potential safety hazards during a single hoisting. After repeated hoisting, it means problems such as long overall operation duration, too high labor cost, serious damage to the body structure, and high safety risk.

[0005] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems: 1. For traditional segmental beam hoisting, construction workers need to manually adjust the distance between the suspension rods to adapt to the distance between the segmental beam lifting holes. The adjustment process requires the assistance of multiple people and cannot be adjusted in place at one time, which is time-consuming and laborious; 2. When using traditional segmental beam hoisting, manual installation of the end anchors and wedge pads of the fine-threaded steel suspension rods is adopted. Construction workers need to repeatedly enter and exit the inner cavity of the segmental beam for installation and disassembly work, which is time-consuming and laborious; 3. The hoisting support stiffness of the four-hanging-point hoisting is low, and the local stress at the hanging points is large. When hoisting large-tonnage segmental beams, it is easy to damage the structure of the segmental beam itself; 4. During the process from production to use of the segmental beam, it needs to experience repeated hoisting. The whole-process hoisting has a long construction period, too high labor costs, serious damage to the structure of the segmental beam itself, and relatively high safety risks. Summary of the Invention

[0017] Preferably, the automatic suspension rod includes:

[0018] An upper support, on the top surface of which an upper active cable mechanism is provided, and the upper support is connected to the transverse sliding block;

[0019] A middle pull rod, which is of a hollow structure and is connected to the lower end of the upper support;

[0024] The present invention also provides a construction method for a segment girder hoist with a link opening and closing type modular longitudinal moving mechanism, including the following steps:

[0025] Step 1: Hoist the segment girder hoist above the segment girder to be hoisted by a lifting device;

[0026] Step 2: According to the transverse spacing and longitudinal spacing parameters of the lifting holes of the segment girder to be hoisted, the control center controls the actions of the transverse actuator and the longitudinal actuator to adjust the transverse and longitudinal spacings of each automatic suspension rod in place;

[0027] Step 3: Continue to lower the segment beam sling, and manually assist in alignment. Insert the lower end of the automated lifting rod into the sling hole of the segment beam.

[0028] Step 4: Lower the segment beam sling to the specified relative height position. The upper active cable mechanism of the automated lifting rod operates, and the eccentric hanging lock is adjusted from the vertical state to the substantially horizontal state.

[0029] Step 5: The lifting equipment lifts the segment beam sling. The eccentric hanging lock forms a stress surface with the inner cavity of the segment beam to be lifted. The passive suspension system ensures that the forces on each automated lifting rod are relatively uniform, and the segment beam to be lifted is hoisted to the specified position.

[0030] Step 6: Lower the segment beam sling to the specified relative height position by the lifting equipment. The upper active cable mechanism in the automated lifting rod resets. Under the action of its own eccentric moment and the lower passive cable mechanism, the eccentric hanging lock resets to the vertical locking state.

[0031] Step 7: The lifting equipment lifts the segment beam sling, and the lower end of the automated lifting rod moves out of the sling hole of the segment beam, completing one hoisting operation.

[0032] Step 8: Repeat Steps 1 to 7 to perform the next hoisting operation.

[0033] The present invention has at least the following beneficial effects:

[0034] 1. The present application uses a link-opening and closing modular longitudinal movement unit equipped with a transverse movement unit to realize the automatic or remote control adjustment of the horizontal and longitudinal distances of the segment beam lifting rods on the sling, quickly adapting to the distance between the sling holes on the segment beam.

[0035] 2. The present application uses an automated locking lifting rod. The cable-opening and closing locking mechanism can automatically complete the locking and unlocking processes, and can automatically realize the constraint and detachment between the segment beam sling and the segment beam to be lifted with the cooperation of the lifting equipment.

[0036] 3. For segment beams with a relatively large tonnage, the present application designs two examples of eight-lifting-rod and six-lifting-rod slings. The passive suspension system ensures that the forces on each lifting rod are relatively uniform during the multi-point hoisting process, and there will be no phenomenon of "idle rods".

[0037] 4. The segment beam automated sling with a link-opening and closing modular longitudinal movement mechanism and its construction method of the present application solve the problems of labor-intensive, low efficiency, easy damage to the segment beam body structure, and high safety risks in the whole process of segment beam hoisting operations.

[0038] Other advantages, objectives, and features of the present invention will be partially reflected by the following description, and partially will be understood by those skilled in the art through the research and practice of the present invention. Description of the Drawings

[0058] The present invention will be further described in detail below with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0059] It should be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials can be obtained from commercial channels unless otherwise specified; in the description of the present invention, the orientation or positional relationship indicated by the terms "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0060] For segment beams with large tonnage and large width, the present application designs two examples. Example 1 is an eight-suspension-rod automatic lifting tool, and Example 2 is a six-suspension-rod automatic lifting tool.

[0061] Example 1

[0062] AsFigures 1 to 16 As shown in the figure, the present invention provides a segment girder spreader with a connecting rod opening and closing type modular longitudinal movement mechanism, including:

[0063] A hoisting beam 1, which includes a hoisting main beam 101 and hoisting lugs 102. The hoisting lugs 102 are arranged on the hoisting main beam 101 for connecting a hoisting device 11;

[0064] A modular longitudinal movement cross beam 4, which includes a pair of longitudinal movement main beams 401. The pair of longitudinal movement main beams 401 are symmetrically distributed on both sides below the hoisting main beam 101 and are connected to the hoisting main beam 101 through a tension bearing mechanism 3. The tension bearing mechanism 3 is hinged to both the pair of longitudinal movement main beams 401 and the hoisting main beam 101;

[0065] A longitudinal movement unit, which is arranged on the pair of longitudinal movement main beams 401 to drive the pair of longitudinal movement main beams 401 to perform an adaptive opening and closing action of approaching or separating from each other longitudinally;

[0066] Automated hanging rods 7, which are even in number and at least 6 are provided. A plurality of automated hanging rods 7 are arranged in one-to-one correspondence and symmetrically on the pair of longitudinal movement main beams 401. The automated hanging rods 7 are slidably arranged transversely on the longitudinal movement main beams 401;

[0067] A transverse movement unit, one is provided corresponding to each automated hanging rod 7. The transverse movement unit is arranged on the longitudinal movement main beams 401 and drives the automated hanging rods 7 to move transversely.

[0068] In the above technical solution, the hoisting lugs 102 are connected to the hoisting device 11, so that the entire spreader is hoisted and moved to directly above the segment girder 12 through the hoisting device 11. The automated hanging rods 7 are arranged on the longitudinal movement main beams 401, and are moved transversely through the transverse movement unit. The pair of longitudinal movement main beams 401 are driven to approach or separate from each other by the longitudinal movement unit, thereby driving the automated hanging rods 7 on both sides to move longitudinally, realizing the transverse and longitudinal movement of the automated hanging rods 7, and adjusting the position. At least 6 automated hanging rods 7 are provided in the present technical solution, which is more than the traditional 4 hanging rods. Therefore, the traditional four-point hoisting support has low stiffness and large local stress at the hanging points, and it is easy to damage the body structure of the segment girder 12 during the hoisting of large-tonnage segment girders 12. Therefore, more than 4 hanging rods are provided in the present technical solution to realize the force of multiple hanging points and protect the body structure of the segment girder 12.

[0069] In another technical solution, a pair of lifting lugs 102 on the lifting main beam 101 are symmetrically arranged. A pair of hanging beams 2 are also symmetrically arranged on the lifting main beam 101. At each position corresponding to a hanging beam 2 on the lifting main beam 101, a guide rod 103, a pair of hanging shoulders 104 and a pair of sliding plates 105 are arranged. The guide rod 103 is arranged on the central axis of the upper surface of the lifting main beam 101 along the length direction thereof. A pair of hanging shoulders 104 are symmetrically fixed on both sides of the lifting main beam 101. A pair of sliding plates 105 are symmetrically fixed on the upper surface of the lifting main beam 101 and are flush with the pair of hanging shoulders 104. The hanging beam 2 includes a hanging main beam 201 and a pair of hanging joints 202. The pair of hanging joints 202 are symmetrically hinged to the top surface of the hanging main beam 201. The hanging main beam 201 is of an inverted U-shaped structure. The hanging main beam 201 is horizontally slidably arranged on the guide rod 103 and the lower bottom surface thereof is in close contact with the pair of sliding plates 105 and is slidably arranged. The pair of vertical surfaces of the hanging main beam 201 are in close contact with the side surfaces and the bottom surface of the hanging shoulders 104 and are slidably connected to the lifting main beam 101.

[0070] In the above technical solution, the lifting beam 1 plays a role of "connecting the upper and the lower". The two lifting lugs 102 are symmetrically fixed on both sides of the upper surface of the lifting main beam 101 and are hinged to the upper lifting equipment 11 through a pin shaft during lifting operations. The guide rods 103 of the two groups of hanging beams 2 are connected through guide plates fixed on the lifting main beam 101 and are symmetrically fixed on both sides of the upper surface of the lifting main beam 101. The four hanging shoulders 104 of the four hanging beams 2 are symmetrically fixed on both sides of the side surface of the lifting main beam 101. The four sliding plates 105 of the four hanging beams 2 are fixed on the upper surface of the lifting main beam 101 and are flush with the hanging shoulders 104 of the hanging beams 2. The guide rods 103 of the hanging beams 2 and the sliding plates 105 of the hanging beams 2 jointly restrict the movement direction of the hanging beams 2.

[0071] The hanging beam 2 is used for the process of the bridge erecting machine to hang and assemble the segmental beam 12. When the lifting equipment 11 lifts the entire lifting tool through the lifting lug 102 and moves it to the segmental beam 12, the hanging beam 2 is used to hang the lifting tool and the lifting equipment 11 is removed. The two groups of hanging beams 2 are symmetrically arranged at both ends of the lifting main beam 101. The upper part of the hanging main beam 201 is hinged to the lower part of the hanging joint 202. The upper part of the hanging joint 202 is connected to the main beam of the bridge erecting machine through high-strength threaded steel or steel wire rope. During work, the entire lifting tool and the segmental beam 12 to be lifted are hung under the main beam of the bridge erecting machine. The lower part of the hanging main beam 201 is designed with an inward concave hanging shoulder 104, which contacts the lower surface of the hanging shoulder 104 on the lifting main beam 101 to form a stress surface during hanging operations and bears the weight of the entire lifting tool and the segmental beam 12 to be lifted. The hanging beam 2 can slide axially along the guide rod 103 of the hanging beam 2 on the lifting main beam 101. The hanging beam 2 does not play a role during the transfer and stacking hoisting of the segmental beam 12.

[0072] In another technical solution, a pair of the tension-bearing mechanisms 3 are symmetrically arranged on the hoisting beam 1. The tension-bearing mechanism 3 includes a balance beam 301 and a pair of vertical tension-bearing rods 302. The balance beam 301 is fixed to the hoisting beam 1 through a pair of tension-bearing mechanism flanges 106. The upper ends of the pair of vertical tension-bearing rods 302 are respectively hinged to the two ends of the balance beam 301 through pins, and the lower ends are respectively hinged to tension-bearing mechanism lugs 402 fixed on the longitudinal movement main beam 401 through pins.

[0073] In the above technical solution, four tension-bearing mechanism flanges 106 are symmetrically fixed on both sides of the hanging main beam 201 for carrying and fixing the tension-bearing mechanism 3. The tension-bearing mechanism 3 is a four-bar linkage mechanism. The tension-bearing balance beam 301 is fixed to the hanging beam 2 through the tension-bearing mechanism flange 106. The two ends of the tension-bearing balance beam 301 are respectively hinged to the upper ends of the two vertical tension-bearing rods 302 through a first tension-bearing mechanism pin 303. The lower ends 703 of the vertical tension-bearing rods 302 are hinged to the tension-bearing mechanism lugs 402 on the modular longitudinal movement cross beam 4 through a second tension-bearing mechanism pin 304. When the distance between the two groups of modular longitudinal movement cross beams 4 changes, the tension-bearing mechanism 3 opens and closes adaptively. The tension-bearing mechanism lugs 402 are fixed on the upper surface of the longitudinal movement main beam 401.

[0074] In another technical solution, the longitudinal movement unit includes at least two longitudinal movement linkage mechanisms 5. The longitudinal movement linkage mechanism 5 includes four longitudinal movement link rods 501 and two longitudinal movement brackets 502. The two longitudinal movement brackets 502 are arranged at an upper and lower interval and are respectively provided with a plurality of guide grooves. The four longitudinal movement link rods 501 are connected end to end in sequence and are hinged through four pins. The two vertices of the longitudinal diagonal are respectively hinged to longitudinal movement link rod flanges 403 arranged on a pair of longitudinal movement main beams 401 through pins. A wear-resistant plate 503 is further arranged between the longitudinal movement link rod flange 403 and the longitudinal movement link rod 501. The two vertices of the transverse diagonal are respectively connected to the guide grooves corresponding to the upper and lower parts of the two longitudinal movement brackets 502 through pin fits. A longitudinal movement actuator 10 is arranged between a pair of longitudinal movement main beams 401 and is used to drive a pair of longitudinal movement main beams 401 to move closer to or away from each other.

[0075] In the above technical solution, a pair of longitudinally moving main beams 401 are connected by a longitudinally moving link mechanism 5, and the adaptability adjustment of the longitudinal spacing is realized under the drive of the longitudinally moving actuator 10. A laterally moving slider 6 is mounted on the longitudinally moving main beam 401, and the flange 403 of the longitudinally moving link 501 is fixed on the upper and lower surfaces of the longitudinally moving main beam 401. The longitudinally moving link mechanism 5 is a four-bar link mechanism. Four longitudinally moving links 501 are hinged end to end to form a rhombus. The two vertex positions of the longitudinal diagonal of the rhombus are respectively hinged to the flange 403 of the longitudinally moving link 501 on a pair of longitudinally moving main beams 401 through two first pins 504 of the longitudinally moving link. The two vertex positions of the lateral diagonal of the rhombus are respectively connected to the guide grooves on the longitudinally moving cage 502 through two second pins 505 of the longitudinally moving link in a matching manner. Four wear-resistant plates 503 are installed between the corresponding surfaces of the longitudinally moving link mechanism 5 and the flange 403 of the longitudinally moving link 501. The number of the longitudinally moving link mechanisms 5 is set according to actual needs, and three are provided on the eight-hanger automatic spreader in this Embodiment 1.

[0076] In another technical solution, the lateral moving unit includes a laterally moving slider 6, which includes a lower slider panel 601, an upper slider panel 602, a slider web 603 and a positioning boss 604. The lower slider panel 601 and the upper slider panel 602 are arranged parallel to each other up and down. The lower slider panel 601 and the upper slider panel 602 are connected into a whole through multiple slider webs 603. A downwardly protruding positioning boss 604 is arranged at the center of the lower slider panel 601. The upper slider panel 602, the lower slider panel 601 and the positioning boss 604 have a vertically penetrating slider center hole 605 at their centers, which is used for passing through and connecting the automatic hanger 7. One laterally moving slider 6 is provided corresponding to each automatic hanger 7. A laterally moving slider 6 slot 404 is provided on the longitudinally moving main beam 401 corresponding to each laterally moving slider 6. The positioning boss 604 is exactly fitted in the laterally moving slider 6 slot 404. The lateral moving unit further includes a plurality of laterally moving actuators 9, which correspond to the plurality of laterally moving sliders 6 one by one and are used for driving the laterally moving sliders 6 to move laterally.

[0077] In the above technical solution, the main function of the transverse sliding block 6 is to carry the automatic suspension rod 7 to adjust or fix the lateral spacing on the modular longitudinal moving cross beam 4. The lower panel 601 of the sliding block contacts the upper surface of the modular longitudinal moving cross beam 4, and the lower clamping boss 604 is inserted into the transverse sliding block 6 clamping groove 404 on the modular longitudinal moving cross beam 4. The clamping boss 604 and the transverse sliding block 6 clamping groove 404 jointly restrict the movement direction of the transverse sliding block 6; the sliding block web 603 supports the upper panel 602 of the sliding block. In addition to the above technical solution, during actual construction, except for the four automatic suspension rods 7 on the outside of the segmental beam 12, the lateral positions of the automatic suspension rods 7 in the middle generally do not need to be adjusted. Therefore, the transverse sliding block 6 clamping grooves 404 in the middle can be set smaller or not set, and there is no need to set a transverse actuator 9. The automatic suspension rods 7 in the middle can be finely adjusted or not adjusted. A limiting device can be set below the automatic suspension rods 7 to restrict their lateral movement even if there are transverse sliding block 6 clamping grooves 404.

[0078] In another technical solution, the automatic suspension rod 7 includes:

[0079] An upper supporting bracket 701, on the top surface of which there is an upper active cable mechanism 706, and the upper supporting bracket 701 is connected to the transverse sliding block 6;

[0080] A middle pull rod 702, which is of a hollow structure and is connected to the lower end of the upper supporting bracket 701;

[0081] A lower end head 703, which is also of a hollow structure and is connected to the lower end of the middle pull rod 702. A horizontally penetrating hanging lock groove is provided in the middle and lower part of the lower end head 703. Winding shafts 708 are provided at both the upper end and the lower end of the hanging lock groove. A load-bearing shaft 705 is provided in the middle of the hanging lock groove, and an eccentric hanging lock 704 is rotatably sleeved thereon. When the eccentric hanging lock 704 is vertical, it is exactly located in the hanging lock groove. When horizontal, both ends protrude outside the two sides of the lower end head 703. The center of gravity of the eccentric hanging lock 704 is biased towards one side and is located below when vertical. One end of a cable 710 is connected to the upper active cable mechanism 706. The other end of the cable 710 passes downward through the middle pull rod 702, winds around the winding shaft 708 at the upper end of the hanging lock groove, and then is connected to the center of the top surface of the eccentric hanging lock 704 when horizontal. A lower passive cable mechanism 707 is provided below the lower end head 703, and it also connects one end of the cable 710. The other end of the cable 710 winds around the winding shaft 708 at the lower end of the hanging lock groove and then is connected to the bottom surface of the eccentric hanging lock 704 when vertical.

[0082] In the above technical scheme, the opening and closing action of the eccentric padlock 704 is realized by the joint action of the upper active wire pulling mechanism 706 and the lower passive wire pulling mechanism 707; the upper active wire pulling mechanism 706 is carried on the upper surface of the upper support 701, and the two ends of the middle pull rod 702 are respectively bolted to the upper support 701 and the lower end head 703, and pass through the center hole of the through-type hydraulic jack 801 and the center hole of the transverse slider 6; the eccentric padlock 704 is hinged to the lower end head 703 through the load-bearing shaft 705, and is connected to the pull wire 710 in the upper active wire pulling mechanism 706 and the lower passive wire pulling mechanism 707. The upper active wire pulling mechanism 706 adopts an electric push rod to push the wire pulling plate, and the wire pulling plate pulls the upper wire 710 to open the eccentric padlock 704 in the vertical closed state to the horizontal state. The lower passive wire pulling mechanism 707 is a gravity traction type reset mechanism, such as a load-bearing block. When the upper active wire pulling mechanism 706 is reset, the eccentric padlock 704 is reset from the horizontal open state to the vertical closed state under its own gravity and the traction of the lower passive wire pulling mechanism 707.

[0083] The closed state A of the eccentric padlock 704: the initial position state of each mechanism of the automated boom 7, the upper active wire pulling mechanism 706 does not work, and the eccentric padlock 704 is stabilized in a vertical closed state under the combined action of its own eccentric torque and the lower passive wire pulling mechanism 707.

[0084] Eccentric padlock 704 open state B: the upper active wire pulling mechanism 706 is actuated to pull the upper wire pulling mechanism 710, overcoming the eccentric moment of the eccentric padlock 704 itself and the resistance moment generated by the lower passive wire pulling mechanism 707, driving the eccentric padlock 704 to a basically horizontal state, and the eccentric padlock 704 is stabilized in a basically horizontal state under the joint action of the upper wire pulling mechanism 710, the lower passive wire pulling mechanism 707 and its own eccentric moment. In the process of driving the eccentric padlock 704 to open.

[0085] Adaptive fitting state C of the eccentric padlock 704: When the automated hoist 7 is in the padlock open state B, pull the automated hoist 7 upwards for a certain distance so that the bearing surface of the eccentric padlock 704 contacts the inner cavity of the segment beam 12. Since the inner cavity surface of the hanging hole of the segment beam 12 is generally an inclined surface, after contacting the horizontal padlock bearing surface, the eccentric padlock 704 will be driven to rotate around the load-bearing axis 705 until the bearing surface of the padlock completes adaptive fitting with the inner cavity surface of the segment beam 12 to form a stable force-bearing surface.

[0086] In another technical solution, the passive suspension system 8 includes a through-type hydraulic jack 801 and an accumulator 802. The through-type hydraulic jack 801 is positioned by a plurality of limit bolts 606, and the limit bolts 606 are bolted to a fixing plate fixed on the upper panel 602 of the slider. The upper support 701 is connected to the through-type hydraulic jack 801 and its lower surface contacts the rod of the through-type hydraulic jack 801. The accumulator 802 is arranged on one side of the transverse movement slider 6 and is connected to the rodless cavity of the through-type hydraulic jack 801 through a hydraulic pipeline.

[0087] In the above technical solution, three limit bolts 606 are installed on the upper panel 602 of the slider to position the through-type hydraulic jack 801. The passive suspension system 8 functions as a flexible support. Each set of automated hanging rods 7 is equipped with a through-type hydraulic jack 801 and an accumulator 802. During the hoisting and suspension operations of the segment beam 12, the automated hanging rods 7 carried by the passive suspension system 8 can adaptively float up and down within a certain range, avoiding the "virtual rod" phenomenon caused by the deformation of the segment beam 12 and the structure of the lifting tool body. The working principle of the passive suspension system 8 is similar to the oil-gas suspension system used on vehicles, which is an existing technology and will not be elaborated again here. Using the accumulator 802 as an elastic element and the through-type hydraulic jack 801 as a displacement compensation element, it solves the "virtual rod" phenomenon caused by the deformation of the segment beam 12 and the structure of the lifting tool body during multi-point hoisting, that is, the poor contact of the force-bearing surface formed by the hanging rod and the inner cavity of the segment beam 12, and the large difference in the forces on each hanging rod or the phenomenon that some hanging rods are not stressed. In the example of the eight-hanging-rod automated lifting tool, due to the large transverse span of the hanging points, in this application, the rodless cavities of two through-type hydraulic jacks 801 are connected in series to form a set of passive suspension units, making the eight-point hoisting equivalent to four-point hoisting in terms of force.

[0088] In another technical solution, an image system module 709 is further provided at the upper end of the lock slot.

[0089] In the above technical solution, the image system module 709 is relied on to identify the position and attitude of the lock of the automated hanging rod 7. The image system module 709 is arranged at the upper end of the lock slot on the lower end head 703 to monitor the position state of the eccentric lock 704 in real time. The image system module 709 is an existing image acquisition and transmission module, which is an existing technology and will not be elaborated here.

[0090] In another technical solution, one end of the transverse movement actuator 9 is hinged to the longitudinal movement main beam 401, and the other end is hinged to the transverse movement slider 6. Both ends of the longitudinal movement actuator 10 are respectively hinged to a pair of longitudinal movement main beams 401. Cable 710 encoders are provided on both the transverse movement actuator 9 and the longitudinal movement actuator 10. The strokes of the longitudinal movement actuator 10 and the transverse movement actuator 9 are monitored through the encoders.

[0091] The eight-hoist automated hoist of embodiment 1 mainly includes: a group of lifting beams 1, two groups of hanging beams 2, two groups of tensioning mechanisms 3, two groups of modular longitudinal beams 4, three groups of longitudinal connecting rod mechanisms 5, eight groups of transverse sliders 6, eight groups of automated hoists 7, a passive suspension system 8, four transverse actuators 9, and two longitudinal actuators 10.

[0092] A transverse sliding block 6, a through-type hydraulic jack 801, an accumulator 802 and a group of automated booms 7 constitute a transverse unit A, which can be moved laterally along the spreader under the drive of a transverse driving device, so as to realize the laterally adjustable spacing of the booms. The pull wire 710 encoder equipped on the transverse actuator 9 is used to monitor the stroke of each transverse actuator 9. Combined with the inherent dimensions of the spreader structure, the lateral spacing of each automated boom 7 can be monitored and controlled in real time.

[0093] Two groups of modular longitudinal moving beams 4 and multiple groups of longitudinal moving connecting rod mechanisms 5 constitute a longitudinal moving unit B, which can be opened and closed along the longitudinal direction of the sling under the drive of the longitudinal moving actuator 10, thereby realizing adjustable longitudinal spacing between the two groups of modular longitudinal moving beams 4. The pull wire 710 encoder equipped on the longitudinal moving actuator 10 is used to monitor the stroke of the longitudinal moving actuator 10. Combined with the inherent size of the sling, the longitudinal spacing of the automated boom 7 carried on the two groups of modular longitudinal moving beams 4 can be monitored and controlled in real time.

[0095] like Figure 17 As shown, the six-suspender automatic spreader mainly comprises: a set of hoisting beams 1, two sets of hanging beams 2, two sets of tension mechanisms 3, two sets of modular longitudinal beams 4, two sets of longitudinal link mechanisms 5, six sets of transverse sliders 6, six sets of automatic spreaders 7, a passive suspension system 8, four transverse actuators 9, and two longitudinal actuators 10. The number of longitudinal link mechanisms 5 is set according to actual needs, and two are set on the six-suspender automatic spreader of this embodiment 2.

[0096] The construction method of the segment beam 12 hanger with a connecting rod opening and closing modular longitudinal movement mechanism of the present application comprises the following steps:

[0097] Step 1: Use the lifting equipment 11 to lift the segment beam 12 to the top of the segment beam 12 to be lifted;

[0098] Step 2: The control center controls the transverse actuator 9 and the longitudinal actuator 10 to move according to the transverse spacing and longitudinal spacing parameters of the lifting holes of the segment beam 12 to be lifted, and adjusts the transverse and longitudinal spacing of each automated suspension rod 7 to the desired position;

[0099] Step 3: Continue to lower the segment beam 12 lifting device, with manual assistance, and insert the lower end 703 of the automated lifting rod 7 into the lifting hole of the segment beam 12;

[0100] Step 4: Lower the sling of the segment beam 12 to the specified relative height position, and the upper active cable mechanism 706 of the automatic suspender 7 operates. The eccentric padlock 704 is adjusted from the vertical state to the substantially horizontal state.

[0101] Step 5: The lifting equipment 11 lifts the sling of the segment beam 12. The eccentric padlock 704 and the inner cavity of the segment beam 12 to be lifted form a stress surface. The passive suspension system 8 ensures that the forces on each automatic suspender 7 are relatively uniform. The segment beam 12 to be lifted is hoisted to the specified position.

[0102] Step 6: The lifting equipment 11 lowers the sling of the segment beam 12 to the specified relative height position. The upper active cable mechanism 706 in the automatic suspender 7 resets. The eccentric padlock 704 resets to the vertical locking state under the action of its own eccentric moment and the lower passive cable mechanism 707.

[0103] Step 7: The lifting equipment 11 lifts the sling of the segment beam 12. The lower end 703 of the automatic suspender 7 moves out of the lifting hole of the segment beam 12, completing one hoisting operation.

[0104] Step 8: Repeat Steps 1 to 7 to perform the next hoisting operation.
