Description

Technical Field

[0001] The present invention relates to the technical field of segmental beam lifting and handling, and more specifically, to a segmental beam suspension rod with a pull-wire opening and closing padlock mechanism and a construction method thereof. Background Art

[0002] Traditional segmental beam hoisting uses bolted threaded steel hangers. After the hangers are inserted into the segmental beam lifting holes, construction workers need to enter the segmental beam cavity to install wedge pads and end anchors. After the crane lifts the segmental beam to the designated location, construction workers need to enter the segmental beam cavity to manually remove the fastened end anchors and wedge pads. Traditional segmental beam hangers require multiple construction workers to repeatedly enter the segmental beam cavity to install and remove wedge pads and end anchors. Sometimes additional brackets or ladders are required to allow construction workers to reach the designated construction location. This repeated lifting not only takes a long time to complete the segmental beam hoisting and has low hoisting efficiency, but also poses a safety hazard to construction.

[0057] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0058] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do 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 cannot be understood as a limitation on the present invention.

[0059] like Figure 1-16 As shown, the present invention provides a segment beam hanger with a pull-wire opening and closing padlock mechanism, comprising:

[0060] A top support 1, which is fixedly supported on the lifting equipment;

[0061] A perforated end 3, which is located below the top support 1, and a padlock groove 31 is provided at the lower part of the perforated end 3, and the padlock groove 31 is vertically arranged and passes through the perforated end 3 laterally;

[0062] A pull rod 2, which is vertically arranged and connects the top support 1 and the perforated end 3;

[0063] An eccentric padlock 4, which is arranged in the padlock slot 31 and is hinged to the perforated end 3 through a load-bearing shaft 41;

[0064] A wire pulling mechanism, which is configured to adjust the rotational position of the eccentric padlock 4 in the padlock slot 31;

[0065] Among them, when the eccentric padlock 4 is rotated to coincide with the padlock slot 31, the cross-sectional length of the eccentric padlock 4 is smaller than the diameter of the segment beam hanging hole, and the eccentric padlock 4 is in a closed state; when the eccentric padlock 4 is rotated to a position perpendicular to the padlock slot 31, the cross-sectional length of the eccentric padlock 4 is greater than the diameter of the segment beam hanging hole, and the eccentric padlock 4 is in an open state.

[0066] In the above technical solution, the top support 1 is a laterally arranged support frame, including a cross bar and two legs, the two legs are located at the two ends of the bottom of the cross bar, and any one of the legs is supported on the lifting equipment and fixedly connected thereto. Segmental beam lifting holes are opened in advance on the segmental beam. When the segmental beam lifting rod is lowered as a whole using the lifting equipment, the pull rod 2 and the perforated end 3 can be lowered vertically and extended into the interior of the segmental beam lifting hole. The eccentric padlock 4 is a geometrically asymmetric structure, and its center of gravity does not coincide with the axis center. When there are no other restrictions (wire pulling mechanism), the eccentric padlock 4 will rotate at a large angle (relative to the vertical direction) in the padlock slot 31 with the load-bearing shaft 41 as the center under the action of gravity. The wire pulling mechanism is configured to control the rotation position (rotation angle) of the eccentric padlock 4: when the wire pulling mechanism is in the initial state, the wire pulling mechanism controls the eccentric padlock 4 to be in a closed state, that is, the eccentric padlock 4 is vertically arranged in the padlock slot 31, coincides with the padlock slot 31, and the edge of the eccentric padlock 4 does not protrude outside the padlock slot 31, so that when the lifting equipment is lowered, the eccentric padlock 4 can smoothly enter the segment beam lifting hole together with the perforated end 3; when the wire pulling mechanism is in the working state, the wire pulling mechanism controls the eccentric padlock 4 to rotate to the open state, and the eccentric padlock 4 is in a basically horizontal state (with the padlock 4 in a basically horizontal state). The slot 31 is vertical), so that when the lifting equipment is lifted in the reverse direction, the eccentric padlock 4 can be smoothly stuck in the lifting hole of the inner cavity of the segmental beam, so that the segmental beam suspension rod and the segmental beam are automatically locked, and then the segmental beam is smoothly lifted to the specified position by using the segmental beam suspension rod; after the segmental beam is lifted to the specified position, the segmental beam suspension rod can return the eccentric padlock 4 to the closed state through the pull-wire mechanism, so that the connection between the segmental beam suspension rod and the padlock surface of the inner cavity of the segmental beam is eliminated, and the unlocking is completed. When the segmental beam suspension rod is lifted upward again, the segmental beam suspension rod can be smoothly moved out of the lifting hole position as a whole, and the next lifting operation can be carried out. Among them, when the eccentric padlock 4 is in the closed state, the two opposite side surfaces of the eccentric padlock 4 are respectively arranged close to the two inner side walls of the padlock slot 31 and are parallel to them, which further limits the rotation of the eccentric padlock 4 in the padlock slot 31. In addition, the plane (upper surface) of the eccentric padlock 4 adjacent to the inner cavity of the segmental beam in the open state is set as the bearing surface 42. When the eccentric padlock 4 is engaged with the inner cavity of the segmental beam, since the inner cavity surface of the segmental beam lifting hole is generally an inclined surface, the eccentric padlock 4 is driven by the overall upward movement of the segmental beam suspension rod and then contacts the horizontal padlock bearing surface 42 and rotates around the load-bearing axis 41 (at this time, the tensioning mechanism passively adapts to the rotation of the eccentric padlock 4 within a certain range) until the bearing surface 42 of the padlock is adaptively fitted with the inner cavity surface of the segmental beam to form a stable force-bearing surface. The eccentric padlock 4 is in an adaptive fitting state at this time, so that the eccentric padlock can better adapt to the inner cavity environment of the segmental beam and be stably mounted at the segmental beam lifting hole, which is beneficial to the subsequent lifting and movement of the segmental beam.Through the above technical scheme, the segmental beam hoisting rod is used in the segmental beam hoisting process, which can reduce the number of construction personnel while ensuring the safety and stability of the hoisting, especially reduce the number of times the construction personnel enter the inner cavity of the segmental beam to operate, and effectively reduce the working hours of the segmental beam hoisting operation, which is both safe and efficient.

[0067] In another technical solution, the segment beam suspension rod with a pull-wire opening and closing padlock mechanism further includes an image recognition module 10, which is arranged inside the perforated end 3, and the image recognition module 10 is configured to monitor the rotation position of the eccentric padlock 4. Specifically, the image recognition module 10 includes a lens and an image sensor. In this embodiment, a mounting slot is provided inside the perforated end 3, which is located above the padlock slot 31 and communicated with it. The mounting slot and the perforations in the perforated end do not interfere with each other. The image recognition module 10 is fixedly installed in the mounting slot and the lens is arranged directly facing the padlock slot 31 below. The image sensor converts the collected optical signal into an electrical signal and transmits it to the operating end display and other devices by wired / wireless means. The image data can be automatically analyzed by the operator through manual analysis / installed software processing and the position state of the eccentric padlock 4 can be determined, thereby facilitating the confirmation of the real-time position state of the eccentric padlock 4 in different processes of the hoisting, assisting in remote construction control and accurately determining the timing of entering the next process, which is conducive to improving construction quality and construction efficiency. In addition, since the lens needs to accurately collect the position data of the eccentric padlock 4 below, the outer end of the lens extends into a portion of the padlock slot 31. In order to avoid the eccentric padlock 4 from colliding with the lens of the graphic recognition module during rotation, in the closed state, the upper part of the eccentric padlock 4 is a right-angled trapezoidal structure, and the lens is arranged directly above the inclined surface of the right-angled trapezoidal structure. Therefore, sufficient space is reserved to ensure the validity of the data collected by the lens, which is conducive to the image recognition module to better identify the rotational position change of the eccentric padlock.

[0068] In another technical solution, the segmental beam hanger with a pull-wire opening and closing padlock mechanism, the top support 1, the pull rod 2, and the perforated end 3 are all provided with vertical and vertical through holes, adjacent perforations are connected to each other, and the perforations in the perforated end 3 are connected to the padlock groove 31; the pull wire mechanism includes:

[0069] An active wire pulling mechanism, comprising an upper wire pulling wire, one end of which is located above the top support 1, and the other end of which passes downward through the top support 1, the pull rod 2, the perforation on the upper part of the perforated end in sequence, and penetrates into the padlock slot 31 to be connected to the middle part of the eccentric padlock 4; a wire pulling device, which is fixedly arranged on the top support 1 and connected to the top end of the upper wire pulling wire, and the wire pulling device is configured to adjust the displacement of the upper wire pulling wire;

[0070] The passive wire pulling mechanism 8 includes a gravity hammer 81, which is located below the perforated end 3; a lower wire pulling wire 82, one end of which is connected to the bottom of the eccentric padlock 4, and the other end passes downward through the perforation at the bottom of the perforated end and is fixedly connected to the gravity hammer 81.

[0071] In the above technical solution, both ends of the pull rod 2 are provided with external threads, the through hole of the top support 1 is an internal threaded hole, the top of the through hole end 3 is provided with an internal threaded hole (the diameter is larger than the through hole diameter), and the pull rod 2 is connected with the top support 1 and the through hole end 3 by threads. The through hole 33 of the through hole end is cut off by the padlock groove 31 and is divided into upper and lower parts. The upper pull wire enters the padlock groove 31 after passing through the through hole of the top support 1, the through hole of the pull rod 2 and the upper through hole of the through hole end, and is fixed in the middle of the bearing surface 42 of the eccentric padlock 4. The eccentric padlock 4 is a gravity eccentric structure. When the wire pulling mechanism is in the initial state, the wire pulling device does not work, but the eccentric padlock 4 needs to be in a relatively stable closed state (vertical balance). Therefore, a passive wire pulling mechanism 8 is provided to provide a large return torque for the eccentric padlock 4. The gravity hammer 81 is connected to the bottom of the eccentric padlock 4 through the lower wire pulling device 82 to ensure that the eccentric padlock 4 has sufficient closing torque and a stable closed state when the wire pulling device does not work. In this embodiment, the upper wire pulling device is fixed to the middle of the bearing surface 42 of the eccentric padlock 4. In order to ensure the vertical balance state of the eccentric padlock 4 in the closed state, the top of the lower wire pulling device 82 is fixed to the bottom of the eccentric padlock 4 near the bearing surface 42.

[0072] When the wire pulling device is not working, the upper wire pulling wire controls the eccentric padlock 4 to tend to a vertical state through its own length, and the lower wire pulling wire 82 further ensures that the eccentric padlock 4 is in a stable closed state through its own gravity. At this time, the eccentric padlock 4 is vertically arranged in the padlock slot 31 and coincides with the padlock slot 31, so that the lower part of the overall segment beam suspension rod can smoothly extend into the segment beam suspension hole; when the wire pulling device is working, the wire pulling device pulls the vertical part of the upper wire pulling wire to move upward, and the upper wire pulling wire exerts pressure on the middle part of the bearing surface 42 of the eccentric padlock 4. When the pulling force is applied, the upper pull wire is inserted into the upper perforation of the perforated end 3, the perforation is located at the axial position of the segment beam suspension rod, and the bearing surface 42 of the eccentric padlock 4 is located on the side of the suspension rod. The eccentric padlock 4 is deflected upward to be perpendicular to the padlock slot 31 under the action of the upper pull wire, and the displacement is controlled by the pull wire device to realize the switching of the eccentric padlock 4 from the closed state to the open state. In the above process, the top end of the passive pull wire rotates with the eccentric padlock 4, and the bottom end of the passive pull wire moves vertically upward under the limiting action of the lower perforation of the perforated end 3. Therefore, the closed and open states of the eccentric padlock 4 can be switched by controlling the working state of the pull wire device, which is convenient for the staff to directly operate from the top (at the top support), and effectively reduces the number of times the staff enters the inner cavity of the segment beam for construction.

[0073] In another technical solution, the segmental beam hanger with a pull-wire opening and closing padlock mechanism further includes a displacement compensation device 9, which is arranged in the perforation at the upper part of the perforated end, and the displacement compensation device 9 includes:

[0074] Two guide units are symmetrically arranged in the vertical direction, and each guide unit includes a fixed plate 92; a movable plate 95, which is arranged at intervals from the fixed plate 92 in the vertical direction; and a guide rod 93, which is arranged vertically and has two ends fixedly connected to the fixed plate 92 and the movable plate 95, respectively; wherein the movable plate 95 of the guide unit is located between the fixed plate 92 and the movable plate 95 of the other guide unit and is slidably connected to the guide rod 93 of the other guide unit;

[0075] A preload spring 96, which is vertically arranged between the moving plates 95 of the two guide units and has two ends fixedly connected to the corresponding moving plates 95;

[0076] The upper pull wire includes a pull wire 1 75, one end of which is fixedly connected to the pull wire device, and the other end downwardly penetrates into the perforation at the upper part of the perforated end 3 and is connected to the fixed plate 92 of the guide unit located above; a pull wire 2 76, one end of which is connected to the fixed plate 92 of the guide unit located below, and the other end downwardly penetrates into the padlock slot 31 and is connected to the middle part of the eccentric padlock 4.

[0077] In the above technical solution, the displacement compensation device 9 plays a role of displacement compensation, and the preload spring 96 plays a role of preload and reset. Specifically, the two guide units are symmetrically arranged up and down, and the movable plate 95 of any guide unit is located between the fixed plate 92 and the movable plate 95 of the other guide unit. Therefore, the fixed plate 92 of the upper guide unit is located above the movable plate 95, and the fixed plate 92 of the lower guide unit is located below the movable plate 95, that is, the fixed plates 92 of the two guide units are both located on the outside, and the two movable plates 95 are located on the inside. When the active wire pulling mechanism is not working, the upper wire pulling does not generate additional pulling force on the eccentric padlock 4. The eccentric padlock 4 is vertically arranged and completely located in the padlock slot 31 (not protruding from the padlock slot 31). The eccentric padlock 4 is in a closed state. At this time, the displacement compensation device 9 is in an initial state (pre-tightened state). The two movable plates 95 slide outward along the corresponding guide rods 93 under the action of the pre-tightening springs 96, and the pre-tightening springs 96 are in a compressed state. The upper wire pulling is divided into two sections, wire pulling 1 75 and wire pulling 2 76. Both wire pulling 1 75 and wire pulling 2 76 are tightened by the reverse force (pre-tightening force) of the pre-tightening springs 96 and maintain a relatively balanced state. When the active wire pulling mechanism is working, the wire pulling device pulls The upper pull wire is moved to cause its vertical part to displace upward. After being subjected to force, the displacement compensation device 9 moves upward with the upper pull wire. The pull wire 1 75 generates an upward pulling force on the guide unit located above, and the pull wire 2 76 generates a downward pulling force on the displacement compensation device 9 under the action of the eccentric padlock 4. In the above process, since the displacement compensation device 9 has a large pre-tightening force, the above-mentioned pulling force is balanced by the pre-tightening force of the pre-tightening spring 96, and the two guide units do not generate relative displacement. Therefore, without affecting the control of the working state of the eccentric padlock 4 by the active pull wire mechanism, the upper pull wire is always kept in an adaptive tensioned state during the working process, so that the eccentric padlock 4 can switch from the closed state to the open state more smoothly. In addition, when the padlock switches from an open state to an adaptive fitting state, the bearing surface 42 of the eccentric padlock adaptively fits with the inner surface of the segment beam. Correspondingly, the eccentric padlock 4 rotates at a certain angle. When the wire pulling device remains stationary (original tensioning state), the lower part of the upper wire is subjected to additional tension from the eccentric padlock 4. At this time, the external tension exceeds the range of the internal preload force of the displacement compensation device 9. The preload spring 96 in the displacement compensation device 9 needs to be further compressed to balance the external tension. That is, after the corresponding guide unit is subjected to force, its moving plate 95 slides along the corresponding guide rod 93 (the guide rod 93 of another guide unit) and compresses the preload spring 96 inward until the elastic force of the preload spring 96 is balanced with the external tension.In the above process, the displacement compensation device 9 is in the displacement compensation state, and the two guide units are relatively displaced outward, and the upper wire stretching caused by the rotation of the eccentric padlock 4 is adaptively compensated for. Thus, the eccentric padlock 4 is allowed to further rotate within a certain range to enter the adaptive fitting state after being in the open state, avoiding the problem that when the wire pulling device cannot adaptively adjust the displacement of the upper wire in a small range, the upper wire is over-stretched and the wire is damaged. Among them, the guide unit located at the top is the upper guide unit, and the fixing plate 92 thereof is also provided with an upper ring 91, which is fixedly connected to the bottom end of the wire 1 75; the guide unit located at the bottom is the lower guide unit, and the bottom of the fixing plate 92 thereof is also provided with a lower ring 94, which is fixedly connected to the top end of the wire 2 76. In this embodiment, the guide rods 93 of the upper guide unit are three guide rods arranged at equal distances along the circumference of the fixed plate 92, and the guide rods 93 of the lower guide unit are three guide rods arranged at equal distances along the circumference of the fixed plate 92. The guide rods 93 of the upper guide unit and the lower guide unit are spaced apart in the horizontal plane to avoid interference. The movable plate of the upper guide unit slides along the guide rods of the lower guide unit, and the movable plate of the lower guide unit slides along the guide rods of the upper guide unit.

[0078] In another technical solution, the segmented beam hanger with a pull-wire opening and closing padlock mechanism also includes a winding device, which includes an upper winding shaft 51, which is arranged in the through hole 33 of the perforated end and is located above the padlock slot 31, one end of the upper pull wire is connected to the pull wire device, and the other end is downwardly wound through the upper winding shaft 51 and connected to the eccentric padlock 4; a lower winding shaft 52, which is arranged in the through hole 33 of the perforated end and is located below the padlock slot 31, one end of the lower pull wire 82 is connected to the eccentric padlock 4, and the other end is downwardly wound through the lower winding shaft 52 and connected to the gravity hammer 81.

[0079] Among them, the upper winding shaft 51 and the lower winding shaft 52 are respectively located at the upper and lower ends of the eccentric padlock 4, and the upper pull wire is in a vertical state in the top support 1, the pull rod 2, and the perforation 33 of the perforated end. After entering the padlock slot 31, the upper pull wire needs to change direction and then connect to the bearing surface 42 of the eccentric padlock 4; the lower pull wire 82 is in a vertical state in the lower perforation of the perforated end 3, and the lower pull wire 82 needs to change direction before entering the perforation 33 of the perforated end. Therefore, the upper winding shaft 51 and the lower winding shaft 52 are set at the reversing position of the upper pull wire and the lower pull wire 82, which facilitates the smooth reversal of the pull wire and connects with the eccentric padlock 4, and also makes the retracting and releasing process of the pull wire smoother and more stable.

[0080] In another technical solution, the segment beam hanger with a wire-pulling opening and closing padlock mechanism, the wire-pulling device includes a wire-pulling base 73, which is fixed to the top of the top support 1, and a guide groove is provided on the wire-pulling base 73; a wire-pulling plate 72, which is arranged in the guide groove and slides along its length direction; an electric push rod 71, which is arranged to drive the wire-pulling plate 72 to move in the guide groove; a fixed pulley 74, which is located at the perforated opening of the top support 1 and fixed on the wire-pulling base 73, one end of the upper wire is fixedly connected to the wire-pulling plate 72, and the other end is passed through the fixed pulley 74 and then downwardly penetrated into the perforation of the top support 1. Among them, the fixed end of the electric push rod 71 is arranged on the wire-pulling base 73, the pushing end is fixedly connected to the wire-pulling plate 72, and the pushing direction is the same as the length direction of the guide groove. The working mode of the wire pulling device is as follows: in the initial state, the wire pulling plate 72 is located at one end of the perforation of the guide groove close to the top support 1. At this time, the stroke of the electric push rod 71 is the smallest, the wire pulling plate 72 is in the initial position, and the active wire pulling mechanism does not generate additional force on the eccentric padlock 4. The eccentric padlock 4 is stably in a vertical closed state under the joint action of its own eccentric torque and the passive wire pulling mechanism 8; in the working state, the electric push rod 71 pushes the wire pulling plate 72 along the guide groove to the specified position, drives the vertical part of the upper wire to move up (winding), drives the eccentric padlock 4 to rotate to a substantially horizontal position, and the eccentric padlock 4 switches to the open state. When the eccentric padlock 4 needs to be reset (return to the closed state), the electric push rod 71 is used again to drive the wire pulling plate 72 back to the initial position. Since the wire pulling plate 72 is located on one side of the perforation and needs to move along the guide groove, the upper wire needs to be reversed at the perforation opening of the top support 1. Therefore, a fixed pulley 74 is provided to facilitate smooth reversal of the upper wire.

[0081] In another technical solution, the segment beam hanger with a pull-wire opening and closing padlock mechanism further includes a limiting mechanism, which includes a limiting shaft 6, which is fixed in the eccentric padlock 4 and the end of which passes through the eccentric padlock 4, the limiting shaft 6 is arranged in parallel with the load-bearing shaft 41, and the length of the limiting shaft 6 is greater than the width of the padlock slot 31; a limiting slot 32, which is arranged on the side wall of the perforated end 3, the limiting slot 32 is located on the same side of the padlock slot 31 and is connected thereto, and when the eccentric padlock 4 is in a closed state, the limiting shaft 6 is correspondingly clamped in the limiting slot 32. Among them, the limiting mechanism is used to limit the excessive rotation of the eccentric padlock 4. In this embodiment, the eccentric padlock 4 can rotate clockwise from a closed state to an open state under the action of the wire pulling mechanism. When the eccentric padlock 4 needs to be reset, the eccentric padlock 4 rotates counterclockwise. Under no restrictions, the eccentric padlock 4 can rotate freely 360° in the padlock slot 31. During rotation, the eccentric padlock 4 is prone to excessive rotation under the action of gravity, resulting in the eccentric padlock 4 still shaking at a certain angle in the padlock slot 31 after being reset, which is not conducive to subsequent construction. Therefore, a limiting shaft 6 is arranged on the same side where the eccentric padlock 4 is connected to the wire pulling mechanism, which vertically passes through the side wall of the eccentric padlock 4, and the two ends extend from the eccentric padlock 4 for a distance corresponding to the position of the limiting shaft 6 on the eccentric padlock 4. A limiting groove 32 is arranged on the side wall of the perforated end 3, so that when the eccentric padlock 4 is reset, the limiting shaft 6 can rotate with the eccentric padlock 4 into the padlock groove 31, and cannot further rotate in the counterclockwise direction under the action of the limiting groove 32, thereby quickly offsetting the rotation speed generated by the eccentric padlock 4 during the rotation process, so that the eccentric padlock 4 can be stably returned to the closed state. In addition, the setting of the limiting mechanism can assist the eccentric padlock 4 in the initial state (when the hoisting equipment is initially lowered), and when the wire pulling mechanism is not working, the eccentric padlock 4 is stably in a vertical closed state under the joint action of its own eccentric torque, the wire pulling mechanism and the limiting mechanism, further ensuring the construction stability.

[0082] The present invention also provides a construction method of a segmental beam hanger with a pull-wire opening and closing padlock mechanism, comprising:

[0083] S1, assemble the segmental beam suspension rod with the pull-wire opening and closing padlock mechanism and fix the top support 1 on the lifting equipment;

[0084] Before lowering, the image recognition module 10 is used to identify whether the eccentric padlock 4 is in a closed state. If so, the next operation is performed; if not, the electric push rod 71 is controlled to move the pull plate 72 to the initial position (the minimum stroke of the electric push rod 71) to put the eccentric padlock 4 in a stable closed state;

[0085] S2, using a lifting device to lower the segment beam suspension rod, so that the perforated end 3 is initially aligned and then penetrated into the preset segment beam suspension hole;

[0086] S3, the wire pulling mechanism is actuated to drive the eccentric padlock 4 to rotate from the closed state to the open state;

[0087] In the above process, the image recognition module 10 is used to monitor in real time whether the eccentric padlock 4 is in an open state. If so, the next operation is performed; if not, the wire pulling mechanism is continued to drive the eccentric padlock 4 to rotate to the open state;

[0088] S4, using a lifting device to lift the segment beam suspension rod until the top surface of the eccentric padlock 4 in the open state is adaptively fitted with the inner cavity of the segment beam, and the eccentric padlock 4 is rotated to an adaptive fitting state;

[0089] S5, further lifting the segmental beam suspension rod, lifting the segmental beam and hoisting it to a designated position;

[0090] S6. After the segment beam is placed at the designated position, the segment beam suspension rod is lowered to move the perforated end 3 downward by a set distance relative to the segment beam suspension hole. The set distance needs to be greater than the distance from the load-bearing shaft 41 to the top of the padlock slot 31 to ensure that the eccentric padlock 4 has enough space to rotate and reset (return to the closed state);

[0091] S7, the wire pulling mechanism is actuated to drive the eccentric padlock 4 to rotate to a closed state;

[0092] During the above process, the image recognition module 10 is used to monitor in real time whether the eccentric padlock 4 is in a closed state. If so, the next operation is performed; if not, the wire pulling mechanism is continued to drive the eccentric padlock 4 to rotate to a closed state;

[0093] S8, lifting the segment beam suspension rod until the perforated end 3 is separated from the segment beam suspension hole, thus completing one lifting operation;

[0094] S9. Repeat the contents of S2-S8 to carry out the next lifting operation.

[0095] In the above technical solution, the eccentric padlock has three working states: closed state, open state and adaptive fit state. Specifically, in this embodiment, the working principle of the wire pulling mechanism driving the eccentric padlock 4 to switch states is as follows:

[0096] Closed state: All mechanisms of the segment beam suspension rod are in the initial position. At this time, the stroke of the electric push rod 71 is the smallest, the wire drawing plate 72 is in the initial position in the guide groove, the active wire drawing mechanism does not work, and the eccentric padlock 4 is stabilized in the vertical closed state under the joint action of its own eccentric torque, the passive wire drawing mechanism 8 and the limit mechanism;

[0097] Open state: Use the electric push rod 71 to push the wire drawing plate 72 to the specified working position, the active wire drawing mechanism overcomes the eccentric torque of the eccentric padlock 4 and the resistance torque generated by the passive wire drawing mechanism 8, and drives the eccentric padlock 4 to rotate (clockwise) to a basically horizontal state. The eccentric padlock 4 is stabilized in a basically horizontal state under the joint action of the active wire drawing mechanism, the passive wire drawing mechanism 8 and its own eccentric torque; in the process of driving the eccentric padlock 4 to open, since the displacement compensation device 9 has a relatively large pre-tightening force, no relative displacement occurs between the upper and lower guide units;

[0098] Adaptive fitting state: when the eccentric padlock 4 is in the open state, continue to pull the segment beam suspension rod upward for a certain distance, so that the bearing surface 42 of the eccentric padlock 4 moves up to contact with the inner cavity of the segment beam. Since the inner cavity surface of the segment beam suspension hole is generally an inclined surface, after contacting with the padlock bearing surface 42 in the horizontal state, the eccentric padlock 4 will be driven to rotate around the load-bearing shaft 41 until the bearing surface 42 of the eccentric padlock 4 is adaptively fitted with the inner cavity surface of the segment beam to form a stable force-bearing surface. In the above process, a driving force is provided for the rotation of the eccentric padlock 4. The power comes from the reverse pressure on the inner surface of the segment beam. The electric push rod 71 does not move (it is still at a larger stroke position). At this time, the eccentric padlock 4 continues to rotate, and the displacement compensation device 9 is subjected to a larger force from the pull wire 76. The upper guide device and the lower guide device are relatively displaced, and the two movable plates 95 compress the preload spring 96 inward until the reverse force of the spring is balanced with the tension of the pull wire 76. Thus, the displacement compensation device 9 realizes automatic adaptive displacement compensation of the eccentric padlock 4 when it continues to rotate in the open state.

[0099] In addition, in the above technical solution, a control system can also be set to realize the full process automation control of the construction of the segment beam suspension rod. The control system is electrically connected to the electric push rod 71, the image recognition module 10, and the lifting equipment. The image data collected by the image recognition module 10 can be automatically analyzed by the software installed in the control system to determine the different working states of the eccentric padlock 4. When the working state meets the requirements for entering the next process, the control system automatically controls the lifting equipment and / or the electric push rod 71 to move according to the construction requirements. For example, in S3, the control system monitors the rotation of the eccentric padlock 4 in real time during the process of controlling the movement of the electric push rod 71. After the electric push rod 71 completes the displacement as required, the control system automatically determines whether the eccentric padlock 4 is in the open state according to the image data collected by the image recognition module 10. After confirming that the eccentric padlock is open, the control system sends a command to the lifting equipment to continue lifting (S4). Thereby, the safety and reliability of the switching process of each process is guaranteed, and the subsequent construction cannot be carried out smoothly due to the failure of the working state of the eccentric padlock to switch to the right position is avoided.
