Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to a multi-functional hoisting device for composite prefabricated railway station components. Background Technology

[0002] Compared to traditional cast-in-place subway stations, prefabricated subway stations utilize factory-prefabricated components and on-site assembly, significantly reducing wet work such as formwork erection and concrete pouring. This can shorten the construction period by 4-6 months, and the components are highly precise and environmentally friendly. The main difference between composite prefabricated subway stations and fully prefabricated subway stations lies in the prefabrication ratio and component weight. Composite prefabricated subway stations have approximately 60% prefabricated components, mainly consisting of composite side walls, central columns, composite beams, prefabricated middle slabs, and composite roof slabs. Some joints (such as circumferential and vertical joints) are connected using cast-in-place concrete or high-strength grout, balancing integrity and waterproofing performance, making them suitable for water-rich soil layers. Fully prefabricated stations, on the other hand, achieve 100% prefabrication, with no cast-in-place work, and have stringent requirements for component precision and sealing.

[0003] During the construction of prefabricated railway stations, prefabricated components need to be hoisted using hoisting equipment. There are two main challenges when hoisting the prefabricated components to the deep foundation pit for main construction. First, large components (such as 30-ton roof slabs) require precise positioning with large lifting equipment. In addition, the deep foundation pit has multiple layers of dense steel supports with a spacing of less than 4m, making the space extremely limited and prone to collision risks. Second, the longitudinal allowable error is only 50mm. After installation, laser positioning and anti-sway systems are required to control the error within 5mm, which is highly dependent on intelligent equipment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a multi-functional hoisting device for prefabricated components of stacked prefabricated railway stations, thereby enabling the adjustment of the angle of the prefabricated components.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-functional hoisting device for composite prefabricated station components, including a gantry crane body, wherein a sliding part is provided on the gantry crane body; The bottom of the sliding part is provided with a first mounting bracket, and the first mounting bracket is provided with mounting holes; The first mounting bracket is equipped with a rotating component to realize the conversion of the longitudinal and transverse directions of the prefabricated component. The rotating component includes a rotating part, a first bevel gear, a mounting base, a drive motor, and a second bevel gear. The rotating component is rotatably mounted at the mounting hole of the first mounting bracket, and a first bevel gear is provided on the top of the rotating component; The number of mounting seats is two, and they are respectively set on the first mounting brackets on both sides of the rotating part. Each of the two mounting seats is equipped with a drive motor, and the output shafts of the two drive motors are connected to a second bevel gear that meshes with the first bevel gear. A second mounting bracket is provided at the bottom of the rotating component; The second mounting bracket is equipped with an angle adjustment assembly to realize the conversion of the prefabricated component from horizontal to vertical. The adjustment assembly includes a slide rail, an electric slide table, a winding section, and a hook. The slide rails are of two types and are both mounted on the second mounting bracket. Each of the two slide rails is equipped with a motorized slide table. Both of the electric slides are equipped with a winding section, and the bottom of the winding section is equipped with a hook; The hook is equipped with a lifting assembly.

[0006] Furthermore, the first mounting bracket has a U-shaped structure, and the surface of the first mounting bracket is in rotational contact with the surface of the rotating component.

[0007] Furthermore, the rotating component includes an upper cylinder and a lower cylinder at the top, and the diameter of the upper cylinder is larger than the diameter of the lower cylinder, and the diameter of the lower cylinder is adapted to the diameter of the mounting hole of the first mounting bracket.

[0008] Furthermore, the second mounting bracket has an inverted U-shaped cross-section in side view and a rectangular ring structure in front view, with the two slide rails respectively located on both sides of the bottom opening of the second mounting bracket.

[0009] Furthermore, the winding section includes a winding motor and a pulley mounted on an electric slide table. The output shaft of the winding motor is connected to a connecting part mounted on the electric slide table. The output end of the connecting part is connected to a winding drum mounted on the electric slide table. A lifting rope is mounted on the winding drum and the pulley, and a hook is mounted at the bottom of the lifting rope.

[0010] Furthermore, the top view of the electric slide table is a rectangular ring structure, and the opening in the middle is designed for the suspension rope to drive the hook to move up and down.

[0011] Furthermore, the hoisting assembly includes a crossbeam with a hook attached, a rotary motor is mounted on the top of the crossbeam, and a lifting device is connected to the output of the rotary motor.

[0012] Furthermore, both the drive motor and the rotary motor are motors with a lock-up function.

[0013] Furthermore, the lifting device has an I-shaped structure and multiple lifting holes for use with other connecting parts to lift prefabricated components.

[0014] Furthermore, an infrared alarm is installed at the top of the horizontal section below the lifting device to provide collision warning during the lifting process.

[0015] The beneficial effects of this invention are reflected in: 1. In use, the present invention, through the setting of the rotating component, can drive the second mounting frame to rotate horizontally during hoisting by the operation of the rotating component. When the second mounting frame rotates, it will drive the hoisting component to move synchronously. The hoisting component is equipped with prefabricated components. Therefore, during the rotation process, the prefabricated components can be converted in the longitudinal and transverse directions to pass through some supports or obstacles. 2. In use, this invention uses a rotating component connected to two lifting components to control the vertical and horizontal movement of the lifting components. When the two lifting components are connected to both ends of the precast component, the vertical angle of the precast component can be adjusted by controlling the height of the two lifting components. At the same time, by adjusting the position of the two lifting components and adjusting their height, adaptability can be improved, thereby enabling the horizontal and vertical conversion of precast components of different specifications. Through the above settings, the advantage of adjustable angle is achieved during the lifting of precast components. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-7 This invention discloses a multi-functional hoisting device for composite prefabricated station components, including a gantry crane body 1, on which a sliding part 2 is provided, wherein the sliding part 2 slides horizontally on the gantry crane body 1, and the horizontal position is changed during the hoisting process by sliding.

[0020] The bottom of the sliding part 2 is provided with a first mounting bracket 3, and the first mounting bracket 3 is provided with mounting holes. The first mounting bracket 3 is a U-shaped structure. The first mounting bracket 3 is provided with a rotating component 4 to realize the conversion of the longitudinal and transverse directions of the prefabricated components. The rotating component 4 includes a rotating part 41, a first bevel gear 42, a mounting base 43, a drive motor 44, and a second bevel gear 45. The rotating component 41 includes an upper cylinder and a lower cylinder at the top, and the diameter of the upper cylinder is larger than the diameter of the lower cylinder. The diameter of the lower cylinder is adapted to the diameter of the mounting hole of the first mounting bracket 3, and the lower cylinder is rotatably mounted at the mounting hole of the first mounting bracket 3. The surface of the first mounting bracket 3 is rotatably attached to the surface of the rotating component 41. Through the diameter adaptation, it is ensured that the rotating component 41 can only rotate at the mounting hole and cannot move horizontally. The top of the rotating component 41 is provided with a first bevel gear 42. It should be noted that the rotating part 41 is provided with ball bearings at the surface contact point with the first mounting bracket 3, and the friction during rotation is reduced by the arrangement of the ball bearings. There are two mounting bases 43, which are respectively set on the first mounting brackets 3 on both sides of the rotating member 41. Each mounting base 43 is equipped with a drive motor 44. The output shafts of the two drive motors 44 are connected to a second bevel gear 45 that meshes with the first bevel gear 42. Under the meshing action between the first bevel gear 42 and the second bevel gear 45, the drive motor 44 can work to drive the rotating member 41 to rotate. The rotation of the rotating member 41 can realize the conversion of the longitudinal and transverse directions. It should be noted that the drive motor 44 is a motor with a locking function, and through the locking function, the horizontal angle of the hoisting can be fixed after the longitudinal and transverse directions are changed. Under the action of the rotating component 4, when each prefabricated component collides with the steel support beam during hoisting, it can rotate 360° to achieve longitudinal and lateral transformation, thereby allowing the prefabricated component to pass through the steel support.

[0021] The bottom of the rotating component 41 is provided with a second mounting bracket 5. The second mounting bracket 5 is connected to the rotating component 41 so that when the rotating component 41 rotates, the second mounting bracket 5 can rotate synchronously. The side view of the second mounting bracket 5 is an inverted U-shaped structure, and the front view is a rectangular ring structure.

[0022] The second mounting bracket 5 is equipped with an angle adjustment component 6 to realize the conversion of the precast component from horizontal to vertical. The adjustment component includes a slide rail 61, an electric slide table 62, a winding part 63, and a hook 64. There are two slide rails 61, which are respectively set on both sides of the bottom opening of the second mounting bracket 5. Two electric slide tables 62 are set on the two slide rails 61, and the two electric slide tables 62 slide on the slide rails 61 to realize the change of horizontal position. Both electric slides 62 are equipped with a winding section 63, and the bottom of the winding section 63 is equipped with a hook 64. The winding section 63 can drive the hook 64 to move vertically up and down. The take-up section 63 includes a take-up motor 631 and a pulley 634 mounted on an electric slide table 62. The output shaft of the take-up motor 631 is connected to a connecting part 632 mounted on the electric slide table 62. The output end of the connecting part 632 is connected to a take-up drum 633 mounted on the electric slide table 62. Under the connecting action of the connecting part 632, when the take-up motor 631 is working, it can drive the take-up drum 633 to take up the winding. A lifting rope 635 is provided on the winding drum 633 and the pulley 634. A hook 64 is provided at the bottom of the lifting rope 635. A lifting assembly 7 is attached to the hook 64. When the winding drum 633 is winding, the lifting assembly 7 can be moved up and down by the hook 64, thereby adjusting the lifting height. The distance between the two hoisting components 7 can be adjusted by the sliding of the electric slide table 62, which can realize the hoisting of prefabricated components of different lengths. The height of the two hoisting components 7 can be adjusted by the winding part 63. At this time, the two ends of the prefabricated component also change accordingly and perform horizontal and vertical conversion. Through the above-mentioned adjustment of distance and height, the hoisting of prefabricated components of different specifications, as well as the horizontal and vertical conversion and angle adjustment during the hoisting process can be realized. It should be noted that the top view of the electric slide table 62 is a rectangular ring structure, and the opening in the middle is designed for the lifting rope 635 to drive the hook 64 to move up and down.

[0023] The hoisting assembly 7 includes a crossbeam 71 with a hook 64 attached to it. A rotary motor 72 is installed on the top of the crossbeam 71. The output of the rotary motor 72 is connected to a lifting device 73. Under the action of the rotary motor 72, the lifting device 73 can be rotated. Thus, when a single hoisting assembly 7 is used to hoist prefabricated components, the longitudinal and transverse directions can be adjusted. When two hoisting assemblies 7 are used together, the longitudinal and transverse angles can be adjusted under the action of the rotary assembly 4. Among them, the rotary motor 72 is a motor with a locking function, and through the locking function, the longitudinal and transverse angles of the prefabricated component are fixed after the longitudinal and transverse angles are adjusted. The lifting device 73 has an I-shaped structure and multiple lifting holes, which are used to cooperate with other connecting parts to lift the prefabricated components.

[0024] It should be noted that all of the above electronic components are electrically connected to the controller, thereby enabling the control and coordinated use of different electronic components.

[0025] An infrared alarm 8 is installed at the top of the horizontal section below the lifting device 73. Under the action of the infrared alarm 8, when the I-shaped lifting device 73 is being lifted between two steel support beams, a collision warning can be provided during the lifting process, thereby ensuring safety during the lifting process and avoiding collision with the support.

[0026] Through the cooperation between the above structures, the hoisting of the composite side wall 101, central column 102, composite beam 103 and precast slab 104 is achieved; During the hoisting of the composite side wall 101, the composite side wall 101 is lifted by two hoisting components 7 and four-point connection. Then, the coiling part 63 on one side of the angle adjustment component 6 works to drive the hoisting component 7 on the corresponding side to rise. At this time, because the heights of the two hoisting components 7 are different, the composite side wall 101 is in an inclined state. Therefore, it can be lowered onto the assembly trolley for subsequent assembly. During the lowering of the composite side wall 101, because the spacing between the steel support beams is small, the composite side wall 101 can be adjusted longitudinally and laterally by rotating the component 4. First, the composite side wall 101 is rotated to be parallel to the steel support beams. At this time, the spacing between the composite side wall 101 and the adjacent steel support beams increases, which can reduce the probability of collision during lowering. When the composite side wall 101 is completely lowered below the steel support beams, the composite side wall 101 can be rotated to be perpendicular to the steel support beams, so that the composite side wall 101 can be placed on the assembly trolley. The I-shaped hoisting assembly 7 is used to position the precast component at the steel support beam when the support cannot be properly installed during hoisting. The gap in the steel support beam increases the range of horizontal movement. When the steel support beam is at the gap, the infrared alarm 8 can monitor and alarm during horizontal movement, and provide emergency notification to prevent collisions between the steel support beam and the hoisting assembly 7, thus ensuring construction safety.

[0027] During the hoisting of the central column 102, it is also lifted by two hoisting components 7. Before hoisting, the central column 102 is placed horizontally, but during subsequent assembly, it is to be vertically rotated. Therefore, before hoisting, the two hoisting components 7 are connected to the side and top of the central column 102 respectively. During the hoisting process, the hoisting component 7 connected to the side rises under the action of the coiling part 63, so that the central column 102 is in an inclined state. By adjusting the spacing and height of the two hoisting components 7, the inclination of the central column 102 is increased, thereby reducing the swaying caused when the top hoisting component 7 is released during the subsequent turning. After the turning is completed, it can be hoisted to the bottom of the steel support beam and assembled with the assembly trolley.

[0028] When hoisting the composite beam 103, the composite beam 103 is first lifted by the hoisting assembly 7 and then lowered. When it is at the bottom, the composite beam 103 will conflict with the steel support beam. At this time, the rotating assembly 4 can rotate 360° to achieve the longitudinal and lateral transformation, so that the composite beam 103 can pass through the steel support and be assembled in conjunction with the assembly trolley.

[0029] When hoisting the precast slab 104, it is first hoisted using the hoisting assembly 7. Then, during the lowering process, the longitudinal and transverse directions, as well as the transverse and vertical directions, can be converted using the rotation assembly 4 and the angle adjustment assembly 6, respectively, so that it can pass through the steel support and be assembled in conjunction with the assembly trolley. Through the above structural settings: 1. The lifting device 73, in conjunction with other connecting parts, is used to connect with the precast components. Then, by moving the gantry crane body 1 and the sliding part 2, the precast components can be moved to the corresponding positions for assembly. During the lifting process, when a single lifting device 73 is used to lift a precast component, the rotary motor 72 can be used to drive the lifting device 73 to rotate, thereby achieving the conversion of the longitudinal and transverse directions. When two lifting devices 73 are used together for lifting, the rotating part 41 can be driven to rotate by the combined action of the first bevel gear 42, the drive motor 44 and the second bevel gear 45. With the connection of the second mounting frame 5 and the angle adjustment component 6, the two lifting devices 73 can rotate synchronously and achieve the conversion of the longitudinal and transverse directions. 2. When the two lifting devices 73 work together for lifting, the winding motor 631 on one side of the electric slide 62 can operate to rotate the corresponding winding drum 633 to wind up the lifting rope 635. As the winding proceeds, the corresponding lifting assembly 7 will rise. Since the two lifting assemblies 7 are connected to both ends of the precast component, when one side of the lifting assembly 7 rises, the angle of the precast component in the vertical direction can be adjusted. By sliding the electric slide 62 on the slide rail 61, the distance between the two lifting assemblies 7 can be adjusted, which can accommodate the lifting of precast components of different specifications. At the same time, it can also be used to adjust the vertical angle, realizing the conversion of the precast component from horizontal to vertical. Through the above settings, the conversion of the longitudinal and transverse directions and the transverse and vertical directions during the lifting of the precast component is realized.

[0030] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
