Description

Technical Field

[0001] The present invention relates to the field of segment beam hoisting equipment, and more specifically, to an automatic segment beam hoist with a hanging modular transverse movement unit. Background Art

[0002] In the prefabrication and assembly construction of concrete segmental beams, the segmental beams need to be hoisted repeatedly, and the positions of the lifting holes of the segmental beams are affected by many factors and have large distribution differences. The traditional segmental beam hoisting uses a hoist with a human-driven sliding hoist. The hoist used is generally a structural form in which the end anchor of the fine-rolled threaded steel bar is installed at the end. The following processes are generally required to complete the hoisting of the segmental beam: first, the construction personnel need to manually adjust the distance between the hoists to adapt to the distance between the lifting holes of the segmental beam; second, the construction personnel need to stand on the top surface of the segmental beam to be hoisted and push the segmental beam hoist to assist the hoist to enter the hoisting position. hole; third, construction personnel need to enter the inner cavity of the segmental beam to install the end anchors and wedge-shaped pads of the fine-rolled threaded steel bars to form a stable force-bearing surface; fourth, the lifting equipment lifts the segmental beam to the designated position; fifth, construction personnel need to enter the inner cavity of the segmental beam again to remove the end anchors and wedge-shaped pads of the fine-rolled threaded steel bars to ensure that the lifting rod can be smoothly moved out of the lifting hole; sixth, the lifting equipment lifts the segmental beam hoist to a certain height, completing a segmental beam hoisting operation; there are problems such as cumbersome hoisting process, large number of construction personnel required, long hoisting cycle, large-tonnage hoisting damage and safety hazards.

[0003] On the other hand, traditional segmental beam hoisting generally uses four-bar hoisting, that is, four-point hoisting. Based on the principle of three points to determine a surface, four-point hoisting has only one static indeterminate problem. If appropriate preload is added to the hoisting bar before the segmental beam is hoisted or the distribution beam method is used, the "virtual bar" phenomenon caused by the deformation of the segmental beam hoist 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 larger tonnage and longer widths, the local load at each force point is larger when four-point hoisting is used, and the support stiffness is smaller. The segmental beam will have a larger deflection during hoisting, and it is easy to cause different degrees of damage to the segmental beam body structure during the hoisting process.

[0036] like Figure 1 to Figure 7 As shown, the present invention provides an automatic lifting device for segmental beams with a hanging modular transverse movement unit, comprising:

[0037] A hoisting beam 1, the top surface of which is fixedly provided with an ear plate 11 for connecting with a lifting device, and both ends of the top surface of the hoisting beam 1 are slidably connected with a hanging beam 12 for connecting with a bridge erecting machine;

[0038] At least three groups of transverse movement units 2, of which two groups of transverse movement units 2 are arranged at the two ends of the bottom of the hoisting beam 1, and the remaining transverse movement units 2 are arranged in the middle of the bottom of the hoisting beam 1; any of the transverse movement units 2 includes a transverse movement main beam 21, which is hung at the bottom of the hoisting beam 1 and can slide along the length direction of the hoisting beam 1; the transverse movement main beam 21 is arranged vertically to the hoisting beam 1, and the two ends of the transverse movement main beam 21 are respectively provided with longitudinal movement units 3, and the longitudinal movement unit 3 includes a longitudinal movement slider 31, and the longitudinal movement slider 31 is slidably connected with the transverse movement main beam 21;

[0039] Each of the longitudinal sliding blocks 31 is correspondingly provided with a passive suspension unit 4 and a suspension rod 5, wherein the passive suspension unit 4 comprises an accumulator 41 and a through-type hydraulic jack 42, and the accumulator 41 is connected to the through-type hydraulic jack 42 via a pipeline;

[0040] The suspension rod 5 passes through the through-type hydraulic jack 42 , the longitudinal sliding block 31 and the transverse main beam 21 in sequence, and the suspension rod 5 and the through-type hydraulic jack 42 can slide along the length direction of the transverse main beam 21 along with the longitudinal sliding block 31 .

[0041] In this technical solution, the hoisting beam 1 plays a role of "connecting the upper and lower parts". The ear plate 11 on the top of the hoisting beam 1 is hinged with the upper lifting equipment through a pin during the hoisting operation; the hanging beam 12 is used for the process of suspending and assembling the segmental beam of the bridge erection machine. Preferably, a hanging joint 121 can be hinged on the hanging beam 12 to connect with the main beam of the bridge erection machine through fine-rolled threaded steel or steel wire rope. When working, the entire hoist and the suspended segmental beam are suspended below the main beam of the bridge erection machine. The hanging beam 12 does not work during the transfer and stacking of the segmental beam.

[0042] The suspension rod 5 can slide along the length direction of the transverse main beam 21 with the longitudinal sliding block 31 to adjust the spacing between the suspension rods 5 at both ends of the transverse main beam 21, that is, the longitudinal spacing between the suspension rods 5 on the hoisting beam 1; the transverse main beam 21 can also slide along the length direction of the hoisting beam 1 to adjust the transverse spacing between the suspension rods 5 on the hoisting beam 1; thereby realizing rapid adaptation to the distance between the hanging holes on the segmental beam. In the passive suspension unit 4, the accumulator 41 is used as an elastic element, and the through-type hydraulic jack 42 is used as a displacement compensation unit, so that the force of each suspension rod is relatively uniform during the hoisting process, and the "virtual rod" phenomenon caused by the deformation of the segmental beam and the hoisting device structure during multi-point hoisting is solved, that is, the force surface formed by the suspension rod and the inner cavity of the segmental beam is poorly contacted, and the force difference of each suspension rod is large, and some suspension rods are not stressed. When targeting the segmental beam with a larger tonnage, three groups of transverse units can be used to form a six-suspender sling or four groups of transverse units can be used to form an eight-suspender sling. When used as an eight-hanging rod sling, since the lateral span of each of the hanging rods is large, the rodless cavities of the two through-type hydraulic jacks 42 can be connected in series to form a group of passive suspension units, so that the eight-hanging point lifting is equivalent to the four-hanging point lifting in terms of force.

[0043] In another embodiment, transverse main beam shoulders 14 are symmetrically arranged at the bottom of the two side walls of the lifting beam 1 corresponding to the positions of the transverse units 2, and at least a pair of hanging boxes 22 are arranged on the top surface of any transverse main beam 21, and the hanging boxes 22 are in an inverted L shape. A pair of the hanging boxes 22 are respectively clamped on the transverse main beam shoulders 14 on both sides of the lifting beam 1, and can slide along the upper surface of the corresponding transverse main beam shoulders 14.

[0044] In this technical solution, the hanging box 22 fixedly arranged on the top surface of the transverse main beam 21 contacts the upper surfaces of the transverse main beam shoulders 14 on both sides of the hoisting beam 1 to form a moving pair, thereby hanging the transverse main beam 21 at the bottom of the hoisting beam 1.

[0045] The two ends of the bottom of the hoisting beam 1 are respectively provided with a transverse driving device 6 corresponding to the position of the transverse moving unit 2, and the transverse driving device 6 includes:

[0046] A transverse screw rod 61 vertically passes through the corresponding transverse main beam 21 and is threadedly connected to the transverse main beam 21. Both ends of the transverse screw rod 61 are rotatably connected to a screw base 62, and the screw base 62 is fixedly connected to the bottom surface of the hoisting beam 1;

[0047] The driving motor 63 is fixedly connected to the bottom surface of the hoisting beam 1 , and the output shaft of the driving motor 63 is fixedly connected to one end of the transverse screw rod 61 .

[0048] The transverse main beams 21 at both ends of the bottom of the hoisting beam 1 can realize adaptive adjustment of the transverse spacing under the drive of the transverse driving device 6. The driving motor 63 drives the transverse screw 61 to rotate, thereby driving the transverse main beam 21 to reciprocate along the transverse main beam shoulder 14. Preferably, an encoder can be provided on the driving motor 63 to monitor the rotation angle of the transverse screw 61. Combined with the inherent size of the sling, the transverse spacing of the corresponding transverse main beam 21 can be monitored and controlled in real time, thereby monitoring and controlling the transverse spacing of each of the suspension rods 5.

[0049] In another embodiment, the longitudinal movement unit 3 also includes a longitudinal movement push rod 32, a fixed end of the longitudinal movement push rod 32 is hinged to the transverse movement main beam 21, and a movable end thereof is hinged to the longitudinal movement slider 31; both ends of the transverse movement main beam 21 are provided with a sliding groove 23 that passes through the upper and lower parts, and the bottom of the longitudinal movement slider 31 is provided with a boss that cooperates with the sliding groove 23.

[0050] In this technical solution, the longitudinal push rod 32 pushes the longitudinal slide block 31 to slide along the slide groove 23, so that the suspension rod 5 moves longitudinally along the hoisting beam 1, thereby adjusting the longitudinal spacing between the suspension rods 5. Preferably, a wire encoder can be provided on the longitudinal push rod 32 to monitor its travel, so that the longitudinal spacing between the suspension rods 5 can be monitored and controlled in real time.

[0051] In another embodiment, a central hole 311 is provided on the longitudinal sliding block 31 for the suspension rod to pass through, and a plurality of limiting bolts 312 for fixing the through-type hydraulic jack 42 are evenly distributed on the upper surface of the longitudinal sliding block 311 along its circumference.

[0052] In another embodiment, a hanging beam shoulder 13 is provided at the top of the two side walls of the hanging beam 1 corresponding to the position of each hanging beam 12, the hanging beam 12 is arranged perpendicular to the hanging beam 1, and the bottom of the hanging beam 12 is respectively clamped with the hanging beam shoulders 13 on both sides of the hanging beam 1, and can slide along the lower bottom surface of the hanging beam shoulders 13.

[0053] In this technical solution, during the hanging operation, the hanging beam 12 contacts the lower bottom surface of the hanging beam shoulder 13 to form a force-bearing surface, which bears the weight of the entire hanger and the hung segment beam; preferably, a guide rod 16 can be provided on the top of the hanging beam 1, so that the hanging beam 12 is sleeved on the guide rod 16, and the hanging beam 12 can slide axially along the guide rod 16. In order to reduce the resistance of the hanging beam 12 when sliding, a slide plate 15 can be provided on the upper surface of the hanging beam shoulder 13.

[0054] In another embodiment, the boom 5 includes a boom body 52, a wire pulling device 51 and an eccentric padlock 53, the eccentric padlock 53 is hinged at the bottom of the boom body 52, and the wire pulling device 51 is fixedly arranged on the boom body 52 to drive the eccentric padlock 53 horizontally or vertically.

[0055] In this technical solution, when the segment beam hoist is lowered to a specified relative height position, the lower end of the suspension rod body 52 is inserted into the segment beam lifting hole, and then the eccentric padlock 53 is driven horizontally by the wire pulling device 51 to achieve automatic padlocking of the suspension rod 5. During contact lifting, the eccentric padlock 53 is driven vertically by the wire pulling device 51 to achieve automatic unlocking of the suspension rod 5.

[0056] Furthermore, the boom body 52 includes an upper support 521, a middle tie rod 522 and a lower end 523 which are coaxially connected from top to bottom; the upper support 521, the middle tie rod 522 and the lower end 523 are all hollow structures; the bottom surface of the upper support 521 abuts against the upper end surface of the through-type hydraulic jack 42, a padlock groove which is vertically provided and horizontally penetrates the lower end 523, and the center of the eccentric padlock 53 is hinged to the lower end 523. The eccentric padlock 53 is an eccentric structure, that is, its center does not coincide with the center of gravity, and the center of the eccentric padlock is hinged to the lower end 523 through a load-bearing shaft, and when the eccentric padlock 53 is in a vertical state, it is just located in the padlock groove.

[0057] Specifically, the wire pulling device 51 includes:

[0058] The upper wire pulling device comprises an electric push rod 512, a wire pulling base 511, a wire pulling plate 514, a fixed pulley 513, a spring displacement compensation device 516, a first wire pulling wire and a second wire pulling wire; the wire pulling base 511 and the fixed pulley 513 are fixedly arranged on the top of the upper support 521, and the spring displacement compensation device 516 is arranged in the lower end 523; the wire pulling base 511 is provided with a guide groove matched with the wire pulling plate 514; the fixed end of the electric push rod 512 is hinged to the wire pulling base 511, and the movable end thereof is hinged to the wire pulling plate 514; one end of the first wire pulling wire is connected to the wire pulling plate 514, and the other end passes through the fixed pulley 513, passes through the upper support 521 and the middle pull rod 522 in sequence, and is connected to the top of the spring displacement compensation device 516; the two ends of the second wire pulling wire are respectively connected to the bottom of the spring displacement compensation device 516 and the eccentric padlock 53;

[0059] The lower pull wire device comprises a gravity hammer 515 and a third pull wire. The gravity hammer 515 is arranged at the inner bottom of the lower end 523. The two ends of the third pull wire are respectively connected to the eccentric padlock 53 and the gravity hammer 515.

[0060] During the use of the wire pulling device 51, in the initial state, the stroke of the electric push rod 512 is the smallest, the upper wire pulling device does not work, and the eccentric padlock 53 is in a vertical state under the action of its own eccentric torque and the gravity hammer 515. When padlocking is required, the electric push rod 512 is started to push the wire pulling plate 514 to the specified position, and overcome the eccentric torque of the eccentric padlock 53 and the resistance torque of the gravity hammer 515, and drive the eccentric padlock 53 to a horizontal state. Then, the suspension rod body 52 is lifted up for a certain distance, so that the eccentric padlock 53 contacts 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 the eccentric padlock 53 in the horizontal state, the eccentric padlock 53 will be driven to rotate around the load-bearing axis until the bearing surface 401 of the padlock is adaptively fitted with the inner cavity surface of the segment beam where it is located, forming a stable force-bearing surface. The spring displacement compensation device is a spring device with a warning force, that is, in the initial state, the warning force is provided by putting the spring in a stretched state, and in the above-mentioned fitting process, the displacement compensation is performed by compressing the spring, thereby allowing the eccentric padlock 53 to be able to rotate within a certain range to enter the padlock adaptive fitting state after being in the open state.

[0061] In another embodiment, an image system unit 54 is provided above the padlock slot, and the image system unit 54 is used to monitor the position of the eccentric padlock 53 to ensure the reliability of the operation when there is no staff in the inner cavity of the segment beam.

[0062] The segment beam automatic lifting device with hanging modular lateral movement unit provided by the present invention comprises the following steps when in use:

[0063] 1. Use the lifting equipment to adjust the segment beam automatic lifting device to the top of the segment beam to be lifted;

[0064] 2. According to the transverse spacing and longitudinal spacing parameters of the lifting holes of the segment beam to be lifted, the transverse and longitudinal spacings of the lifting rods 5 are adjusted to the desired position by operating the transverse driving devices 6 and the longitudinal push rods 32;

[0065] 3. Continue to lower the segmental beam automated lifting device, with manual assistance for alignment, and insert the lower end 523 of the lifting rod 5 into the segmental beam lifting hole;

[0066] 4. The segment beam automatic lifting device is lowered to a specified relative height position, and the eccentric padlock 53 is adjusted from a vertical state to a substantially horizontal state through the wire pulling device 51 on the upper part of the lifting rod 5;

[0067] 5. The segment beam automatic lifting device is lifted by a lifting device. The eccentric padlock 53 forms a force-bearing surface with the inner cavity of the segment beam to be lifted. The passive suspension system 4 ensures that the force of each suspension rod 5 is relatively uniform, and the segment beam to be lifted is lifted to a designated position.

[0068] 6. The segment beam automatic hoist is lowered to a specified relative height position by a lifting device, the wire pulling device 51 in the suspension rod 5 is reset, and the eccentric padlock 53 is reset to a vertical locked state under the action of its own eccentric moment and the gravity hammer 515;

[0069] 7. The segment beam automated lifting device is lifted by a lifting device, and the lower end 523 of the lifting rod 5 is moved out of the segment beam lifting hole, completing a lifting operation;

[0070] Repeat steps 1 to 7 for the next lifting operation.

[0071] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
