Description

Technical Field

[0001] The utility model relates to the technical field of segment beam lifting and handling equipment, in particular to an edge hook type segment beam automatic lifting device. Background Art

[0002] Concrete segmental beams need to be lifted repeatedly during the prefabrication, storage and transportation processes. The lifting equipment and segmental beams are usually connected by a hoisting rod, and the movement of the hoisting rod is generally driven by manpower. The following steps are generally required to complete a lifting of the segmental beam: First, the construction workers adjust the distance between the hoisting rods to match the distance between the lifting holes on the segmental beam; second, the construction workers stand on the segmental beam to assist in positioning; third, the construction workers enter the inner cavity of the segmental beam to install the end anchors and wedge-shaped pads; fourth, the lifting equipment lifts the segmental beam to the designated position; fifth, the construction workers enter the inner cavity of the segmental beam again to remove the end anchors.

[0003] Traditional segmental beam hoists have high requirements for the positioning accuracy of the hoist rods. The installation and removal of anchors are time-consuming and labor-intensive and pose safety hazards. The hoisting operation has problems such as complicated process, long hoisting cycle and high labor cost.

[0004] In order to solve this technical problem, a Chinese invention patent application with the patent number "CN114084794B" and entitled "A Segmental Beam Automated Lifting Device and Construction Method Thereof" proposes a lifting device for segmental beams, which comprises a lifting beam, a rotating crossbeam, a pair of movable longitudinal beams, a longitudinal sliding block and a segmental beam lifting rod: the top center of the lifting beam is connected to the hook or connector of the lifting equipment; the rotating crossbeam is parallelly located below the lifting beam, and the rotating crossbeam is rotatably connected to the lifting beam through an adapter; a pair of movable longitudinal beams are slidably arranged on the longitudinally opposite sides of the rotating crossbeam, and the movable longitudinal beam is provided with A pair of guide grooves are arranged along the center line of the moving longitudinal beam; a longitudinal slider is arranged for each guide groove of each moving longitudinal beam, a pair of longitudinal sliders are arranged above the guide grooves and connected by a slider connecting rod; a segment beam suspension rod is arranged for each longitudinal slider, the segment beam suspension rod vertically passes through the longitudinal slider and is rotatably connected with the longitudinal slider, the upper end of the segment beam suspension rod is connected to a slewing push rod, the slewing push rods of the two segment beam suspension rods corresponding to the same moving longitudinal beam are hinged through the suspension rod connecting rod, the segment beam suspension rod just passes through the guide groove and the lower end is fixed with a padlock at the connection hole, which matches the segment beam lifting hole. The hoisting process of the hoist is safe and orderly, and the hoisting can be accurate and correct, which can reduce the number of workers during hoisting construction and ensure construction safety. However, this type of hoisting device requires that the segmental beam to be hoisted has a hoisting hole, and that the hole padlock at the lower end of the segmental beam hoisting rod is in contact with the inner cavity of the segmental beam hoisting hole to form a force-bearing surface. The hole padlock is inserted into the segmental beam hoisting hole and then rotated 90° to complete the padlocking. This requires that hoisting holes be reserved in the segmental beam when the segmental beam is prefabricated, which invisibly increases the difficulty of prefabrication of the segmental beam. In addition, during subsequent hoisting, the hole padlock on the hoisting rod needs to be accurately inserted into the reserved hole, which increases the difficulty of hoisting and greatly reduces the hoisting efficiency.

[0043] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The present application relates to an edge hook type segmental beam automatic hoist. The hoist of the present application is used to hook the longitudinal edge positions of the segmental beam. There is no need to reserve holes on the segmental beam. The hoist of the present application can be automatically adjusted, and can be automatically adjusted horizontally and vertically, so that segmental beams of different specifications can be hoisted. The adjustment process is carried out automatically, and there is no need for manual adjustment operations on site, thus avoiding the safety risks of personnel entering the hoisting construction site.

[0045] Specifically, Figures 1 to 5As shown, an edge hook type segmental beam automatic hoist of the present application includes a hoisting main beam 1, two groups of longitudinal bearing structures and four groups of transverse bearing structures. The hoisting main beam 1 is a transverse main beam connected to the lifting rope 2. The hoisting main beam 1 is the bearing foundation of the entire hoist. The hoisting main beam 1 of the present application is a hollow square tubular beam body; the two groups of longitudinal bearing structures are disposed on both sides of the hoisting main beam 1, and the longitudinal bearing structures can be connected to the hoisting main beam 1 in a transversely movable manner. Each group of longitudinal bearing structures includes two longitudinal beams 3 disposed on both sides of the hoisting main beam 1 in the longitudinal direction, and one end of the longitudinal beam 3 can be longitudinally telescopically moved and connected to the longitudinal bearing structure; the transverse bearing structure includes a balance beam 4 connected to the other end of the longitudinal beam 3 and a swivel hook structure installed at both ends of the balance beam 4, the swivel hook structure includes a swivel hanger 5 hingedly connected to the end of the balance beam 4 and rotatable around a vertical axis, and a balancing boot 6 arranged at the lower end of the swivel hanger 5 for hooking the edge of the segmental beam.

[0046] The lifting main beam 1 of the present application is directly connected to the lifting rope 2. The lifting main beam 1 of the present application has a raised beam structure in the middle. Such a structure can make the connection point in the middle and the connection points on both sides have a certain height difference in the vertical direction to avoid the problem of mutual interference. In order to facilitate the connection between the lifting main beam 1 and the lifting rope 2, two groups of lifting ear plates 17 connected to the lifting rope 2 are provided on the lifting main beam 1 of the present application. The two groups of lifting ear plates 17 are symmetrically arranged with the midpoint of the lifting main beam 1 as the center. To connect the lifting rope 2, the lifting rope 2 only needs to pass the lifting rope 2 through the connecting hole on the lifting ear plate 17; the longitudinal load-bearing structure is a structure that can be stretched and contracted in the longitudinal direction. The longitudinal load-bearing structure is mainly to facilitate the adaptation of different segment beams along the longitudinal direction. When the longitudinal length of the hoisted segmental beam is long, the longitudinal beam 3 can be stretched longitudinally to adjust the extended length of the two longitudinal beams 3 to match the longitudinal length of the segmental beam; conversely, when the longitudinal length of the hoisted segmental beam is short, the extended length of the longitudinal beam 3 can be contracted to match it. The longitudinal bearing structure can adapt to the hoisting of segmental beams of various lengths, making the application range of the entire sling wider; the balance beam 4 of the transverse bearing structure has two lifting points, namely two sets of balance boots 6 at both ends of the balance beam 4, and the swivel hook structure can adjust the rotation angle of the balance boot 6, so that the balance boot 6 can be correctly hooked on the edge of the segmental beam without reserving lifting holes on the segmental beam.

[0047] During actual lifting, the hoisting equipment is used to lift the sling to the top of the segmental beam, and each adjustment mechanism is adjusted to the standby position; according to the structural parameters of the segmental beam to be lifted, the longitudinal bearing structure adjusts the extension length of the longitudinal beam 3, the longitudinal bearing structure adjusts the horizontal position of the balance beam 4, and adjusts the position of the balance shoe 6 to align it with the appropriate lifting point on the edge of the segmental beam; the sling is lowered, and the balance shoe 6 is immersed under the top plate of the segmental beam; the longitudinal bearing structure adjusts the longitudinal beam 3 to shrink the longitudinal beam 3, and the balance beam 4 clamps the two sides of the segmental beam to suppress the swing of the sling; the slewing hook structure drives the balance The balancing shoe 6 rotates and enters the bottom of the top plate of the segmental beam; the hoist is lifted, the balancing shoe 6 contacts the segmental beam, the balancing shoe 6 and the balancing beam adaptively rotate, the balancing shoe 6 adaptively sticks to the load-bearing inclined surface, and the balancing beam adaptively adjusts the force of two adjacent support points; the segmental beam is lifted and hoisted to the top of the specified position by the lifting equipment; the hoist is lowered, the segmental beam falls into place, and the longitudinal bearing structure adjusts the longitudinal beam 3 to move the balancing shoe 6 out from the bottom of the segmental beam, and the constraint between the hoist and the segmental beam is released; the hoist is reset, and the above steps are repeated for the next lifting operation.

[0048] In some embodiments of the present application, the present embodiment optimizes the above-mentioned swivel hook structure, specifically, Figure 1 , 3 As shown in Figure 4, the swivel hook structure includes a swivel base 7 and a hook base 8. The swivel base 7 is fixed on the upper end surface of the balance beam 4, and the swivel base 7 is connected to the upper end of the swivel suspension rod 5 passing through the balance beam 4; one end of the hook base 8 is connected to the lower end of the swivel suspension rod 5, and the other end extends in the horizontal direction; a balancing base 9 is provided on the part of the hook base 8 that exceeds the swivel suspension rod 5, and the balancing boot 6 is fixedly connected to the balancing base 9 through a balancing pin.

[0049] That is, the balancing boot 6 of this embodiment is rotatably hingedly connected to the balancing base 9 through a horizontal balancing pin. Such a structure enables the balancing boot 6 to automatically adapt to the structure of the edge position of the segmental beam, so that the balancing boot 6 can adapt to the inclined surface of the lower part of the segmental beam top plate, making the contact between the two more comprehensive and stable.

[0050] The driving of the slewing boom 5 of the present embodiment is carried out by automatic operation. Figures 1 to 5 As shown, an adjusting electric cylinder 10 for driving the slewing base 7 to rotate around a vertical axis is provided on the hoisting main beam 1. When the balancing shoe 6 is rotated, the adjusting electric cylinder 10 is controlled to drive the slewing base 7 to rotate around the vertical axis, thereby achieving the purpose of adjusting the balancing shoe 6, so that the balancing shoe 6 can be accurately hooked to the edge of the segment beam.

[0051] During actual hoisting, the electric cylinder 10 is first adjusted to drive the slewing base 7 to rotate around the vertical axis, so that the balancing shoe 6 is rotated to the horizontal transverse direction, that is, the balancing shoe 6 is parallel to the longitudinal edges of the segment beam. When the balancing shoe 6 is moved into position and the segment beam edge needs to be hooked, the electric cylinder 10 is adjusted to drive the slewing base 7 to rotate around the vertical axis, so that the balancing shoe 6 is rotated 90° to the inside of the segment beam, that is, the balancing shoe 6 is rotated to the bottom of the segment beam top plate. Finally, under the operation of the hoisting equipment, the balancing shoe 6 is moved to the horizontal transverse direction. The balancing shoe 6 moves upward and contacts the lower end surface of the segment beam top plate. Under the action of the segment beam top plate, the balancing shoe 6 rotates around the balancing axis and adaptively fits to the lower end surface of the segment beam top plate to complete the hooking operation with the segment beam. After the segment beam is hoisted, under the action of the hoisting equipment, the balancing shoe 6 moves downward and breaks away from the contact with the lower end surface of the segment beam top plate. The electric cylinder 10 is adjusted to drive the rotary base 7 to rotate around the vertical axis, so that the balancing shoe 6 rotates to the horizontal transverse direction and completely escapes from under the segment beam top plate.

[0052] In other embodiments of the present application, the longitudinal bearing structure is optimized. Specifically, Figures 1-2 As shown, the longitudinal bearing structure includes a hanging box 11, which is a hollow cylindrical structure arranged along the longitudinal direction. The two longitudinal ends of the hanging box 11 are open, and a longitudinal moving electric cylinder for driving the longitudinal beam 3 to move longitudinally is arranged in the hanging box 11.

[0053] Two longitudinal beams 3 are arranged on each hanging box 11, and the two longitudinal beams 3 are placed on both sides of the hanging box 11 in the longitudinal direction and arranged opposite to each other. One end of the longitudinal beam 3 can be sleeved in the hanging box 11 in a longitudinally movable manner, and then the longitudinal moving cylinder in the hanging box 11 is used for telescopic operation. The whole structure is simple in design, and can automatically adjust the longitudinal length to adapt to the hoisting operation of segment beams of different specifications.

[0054] In addition, the hanging box 11 of this embodiment can be moved laterally on the hanging main beam 1. Figure 1 , 2 As shown in Figure 4, a driving structure for driving the hoisting box 11 to move laterally is provided between the hoisting box 11 and the hoisting main beam 1. The driving structure includes a transverse screw rod 12, which passes through the hoisting box 11 in the transverse direction, and one end of the transverse screw rod 12 is hingedly connected to the hoisting main beam 1 so as to be rotatable around a horizontal transverse axis, and the other end is provided with a transverse motor 13 for driving the transverse screw rod 12 to rotate.

[0055] Two sets of driving structures are arranged on the hoisting main beam 1, each set of driving structures corresponds to the hoisting box 11 one by one, and each set of driving structures includes a transverse screw rod 12 and a transverse motor 13 disposed on both sides of the longitudinal direction of the hoisting main beam 1. When adjusting the lateral position of the hoisting box 11, the transverse screw rod 12 is driven to rotate by the transverse motor 13, and the rotation of the transverse screw rod 12 is converted into the lateral movement of the hoisting box 11. The transverse motors 13 on both sides of the hoisting box 11 work together to drive the hoisting box 11 to move laterally to the designed position.

[0056] The lateral movement of the hanging box 11 is achieved based on the guide structure. Figure 1 and 2 As shown, a guide structure for limiting the non-lateral movement of the hanging box 11 is provided between the hanging box 11 and the hoisting main beam 1. The guide structure includes a transverse base 14, which is a raised strip structure provided on the longitudinal side of the hoisting main beam 1 and extending in the transverse direction. The hanging box 11 is provided with a transverse hanging box 15 connected to the transverse base 14 and hooked on the upper end surface of the transverse base 14 so that the hanging box 11 can only slide in the transverse direction.

[0057] The transverse moving base 14 is a strip guide rail protruding from the hoisting main beam 1 in the longitudinal direction, and the transverse moving hanging box 15 is a hooking structure hooked on the upper end surface of the transverse moving base 14. Two groups of transverse moving hanging boxes 15 are arranged on each hoisting box 11. The two groups of transverse moving hanging boxes 15 are arranged opposite to each other in the longitudinal direction and are placed on both sides of the longitudinal direction of the hoisting main beam 1. The hoisting main beam 1 and the hoisting box 11 are connected as a whole through the combined structure of the transverse moving hanging box 15 and the transverse moving base 14, so as to limit the relative displacement of the two in the non-transverse direction.

[0058] In a further embodiment of the present application, the connection structure between the balance beam 4 and the longitudinal beam 3 is optimized. Specifically, Figure 1 , 2 As shown in FIG. 4 , a lower ear plate 16 is provided at the center of the balance beam 4 , and an upper ear plate corresponding to the lower ear plate 16 is provided on the longitudinal beam 3 , and the lower ear plate 16 and the upper ear plate are hingedly connected as a whole through a balance pin shaft arranged along the horizontal longitudinal direction.

[0059] There is a hinged structure between the balance beam 4 and the longitudinal beam 3. The balance beam 4 can rotate relative to the longitudinal beam 3. In this way, when the balance boot 6 hooks the segment beam, it can adaptively rotate. The balance beam 4 adaptively adjusts the force of two adjacent support points, and the structural force is more stable.

[0060] During actual lifting, the lifting device is lifted to the top of the segment beam by the lifting equipment and adjusted to the standby position; according to the structural parameters of the segment beam to be lifted, the longitudinal electric cylinder in the lifting box 11 is driven to adjust the extension length of the longitudinal beam 3, so that the longitudinal spacing between the balance beams 4 at both ends of the longitudinal beam 3 is greater than the longitudinal length of the segment beam, and the transverse motor 13 is driven. The transverse motor 13 drives the transverse screw 12 to rotate, thereby driving the lifting box 11 to slide along the transverse base 14 until each balance shoe 6 reaches the designed lifting position, and the balance shoe 6 is aligned with the appropriate lifting point on the edge of the segment beam. The adjustment electric cylinder 10 drives the rotary base 7 to rotate around the vertical axis, so that the balance shoe 6 rotates to the horizontal transverse direction, that is, the balance shoe 6 is parallel to the longitudinal edges of the segment beam; the lifting device is lowered, and the balance shoe 6 is immersed under the top plate of the segment beam; The longitudinal electric cylinder adjusts the longitudinal beam 3 to make the longitudinal beam 3 shrink, and the balance beam 4 clamps the two sides of the segmental beam to suppress the swing of the hoist; the adjusting electric cylinder 10 drives the rotating base 7 to rotate around the vertical axis, so that the balance boot 6 rotates 90° to the inside of the segmental beam, that is, the balance boot 6 is rotated to the bottom of the top plate of the segmental beam; the hoist is lifted, the balance boot 6 contacts the segmental beam, the balance boot 6 and the balance beam 4 rotate adaptively, the balance boot 6 adaptively sticks to the load-bearing inclined surface, and the balance beam 4 adaptively adjusts the force of two adjacent support points; the segmental beam is lifted and hoisted to the top of the designated position by the lifting equipment; the hoist is lowered, the segmental beam is in place, and the longitudinal electric cylinder adjusts the longitudinal beam 3 to extend outward, so that the balance boot 6 moves out from the bottom of the segmental beam, and the constraint between the hoist and the segmental beam is released; the hoist is reset, and the above steps are repeated for the next lifting operation.

[0061] The longitudinal direction of the present application refers to the direction of the segment beam along the bridge. Figure 4 The up-down direction shown in the figure; the transverse direction refers to the transverse direction of the segment beam, such as Figure 4 The left and right directions shown in the figure; the vertical direction refers to the vertical direction of the segment beam, such as Figure 4 The direction shown is perpendicular to the paper plane.
