Description

Technical Field

[0001] The invention belongs to the field of hoisting technology, and in particular to a device for accurately hoisting a single-frame structure in an annular cable-supported grid structure. Background Art

[0002] The precise lifting equipment for single-frame structures in annular cable-supported grid structures refers to the construction technology that uses advanced measuring, monitoring and lifting equipment to accurately plan, measure, locate and install a single structural unit (single-frame structure) during the construction of the annular cable-supported grid structure, so as to ensure that each structural unit can be accurately positioned to meet the design requirements and ensure the safety and stability of the overall structure.

[0003] In the existing technology, a single-frame structure is lifted steadily by lifting equipment (such as a tower crane, crawler crane, etc.), and a real-time monitoring system is used to accurately control the position, height and posture during the lifting process to ensure that the single-frame structure can be accurately positioned according to the predetermined trajectory. Finally, after the lifting is completed, necessary adjustments and verifications are performed to ensure that the installation accuracy of the single-frame structure meets the design requirements.

[0004] There are still some problems in the actual application of the above scheme. Although the existing technology can complete the lifting, the drum of the traditional lifting equipment is usually one or more cylindrical parts with multiple ropes wound on it. When the drum rotates, the rope will be rolled up or released as the drum rotates, thereby realizing the lifting and lowering control of the hoisted object. The pulley block is a complex mechanism composed of a series of pulleys, which is used to change the direction of the rope and distribute the weight of the hoisted object. These pulleys are usually fixed on a frame and work with the drum to ensure that the rope can move smoothly. However, since the original intention of the design of the traditional lifting equipment is to achieve the smooth lifting and lowering of the entire hoisted object, its drum and pulley block do not provide an independent mechanical structure for adjusting the length of a single rope. This means that during the lifting process, if the rope length of a specific part needs to be adjusted to correct the tilt or offset of the hoisted object, the operator will not be able to directly achieve this function through the equipment itself. Instead, they need to rely on additional tools or methods to manually adjust the rope length, which not only increases the complexity and risk of the operation, but also affects the efficiency and accuracy of the lifting operation.

[0005] To this end, the present invention provides a device for accurately lifting and placing a single-frame structure in an annular cable-supported grid structure. Summary of the invention

[0017] Preferably, the fixed ring is arranged so as not to rotate when the rotating gear rotates, but can drive the fixed ring to move synchronously when the rotating gear moves horizontally, and both ends of the oblique rod are provided with oblique structures.

[0019] Preferably, the elastic cable is used to pull the ratchet teeth to rotate around the fixed column, the first spring is used to reset the oblique block, and the remaining components of the linkage buckle mechanism except the fixed ring, T-shaped rod and the first guide groove are symmetrically distributed in two groups about the central axis of the support frame.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The single-frame structure precise lifting and positioning equipment in the annular cable-supported grid structure described in the present invention, since the length of the calibration rod is greater than the length of the rotating gear, the side teeth of the rotating gear will enter the calibration hole opened on the side of the first winding drum before the side teeth of the rotating gear mesh with the side teeth of the first gear ring. Since the calibration hole is also a double-sided oblique structure, the first winding drum will rotate when the calibration rod is inserted into the calibration hole. At the same time, since the calibration hole corresponds to the protruding part of the side teeth of the first gear ring, and the calibration rod corresponds to the groove part of the side of the rotating gear, when the calibration rod is inserted into the calibration hole, it can ensure that the side teeth of the rotating gear are accurately docked with the teeth on the first gear ring. Through the cooperation of the calibration rod and the calibration hole, when the side of the rotating gear is against the side of the first gear ring or the second gear ring, its teeth remain in a meshing state, thereby reducing the wear of the equipment. At the same time, the reciprocating motion of the electric telescopic rod can adjust the relationship between the rotating gear and the first gear ring or the second gear ring, thereby achieving the purpose of adjusting a single rope, thereby improving the efficiency and accuracy of the lifting operation.

[0022] 2. The single-frame structure precise lifting and positioning equipment in the annular cable-supported grid structure described in the present invention, when the rotating gear moves to the other side, it will drive the fixed ring to move synchronously, and drive the inclined rod to move during the movement. Since the inclined rod does not resist the inclined block, the first spring will reset, and at the same time drive the inclined block to move downward along the guide of the second guide groove. At this time, the elastic cable is in a relaxed state, and the second spring will also reset due to the lack of external force. Therefore, the ratchet teeth will reset around the fixed column at this time, thereby engaging with the teeth on the ratchet ring. Since the teeth on the outer ring surface of the ratchet ring and the ratchet teeth are both ratchet structures, the ratchet ring will be stuck at this time. Since the ratchet ring is fixed on the outer ring surface of one side of the first winding drum, the first winding drum will also be stuck, thereby preventing the rope on the outer ring surface of the first winding drum from being stretched by external force, thereby improving the safety of the equipment during construction.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1

[0038] like Figures 1 to 8 As shown, the single-frame structure precision hoisting device in the annular cable-supported grid structure according to the embodiment of the present invention comprises a hoisting device 1, wherein the hoisting device 1 comprises a tower crane 101, a sling 102 is fixedly connected to the tower crane 101, and a reciprocating adjustment mechanism 2 is arranged at the bottom of the hoisting device 1;

[0039] The reciprocating adjustment mechanism 2 includes a protective box 201 fixedly arranged at the bottom of the hanging column 102, a rotating gear 207 is rotatably arranged inside the protective box 201, a first winding drum 210 is rotatably arranged inside the protective box 201, and a second winding drum 214 is rotatably arranged inside the protective box 201. Through the movement of the rotating gear 207, any group of the first winding drum 210 or the second winding drum 214 can be operated to reel in and unwind the line.

[0040] Specifically, although the prior art can complete the hoisting, the drum of the traditional hoisting equipment 1 is usually one or more cylindrical parts with multiple ropes wound on it. When the drum rotates, the rope will be rolled up or released as the drum rotates, thereby realizing the lifting and lowering control of the hoisted object. The pulley block is a complex mechanism composed of a series of pulleys, which is used to change the direction of the rope and distribute the weight of the hoisted object. These pulleys are usually fixed on a frame and work with the drum to ensure that the rope can move smoothly. However, since the original intention of the design of the traditional hoisting equipment 1 is to achieve the smooth lifting and lowering of the entire hoisted object, its drum and pulley block do not provide an independent mechanical structure for adjusting the length of a single rope. This means that during the hoisting process, if the rope length of a specific part needs to be adjusted to correct the tilt or offset of the hoisted object, the operator will not be able to directly achieve this function through the equipment itself. Instead, they need to rely on additional tools or methods to manually adjust the rope length, which not only increases the complexity and risk of the operation, but also affects the efficiency and accuracy of the hoisting operation.

[0041] Therefore, the present invention solves this problem by setting up corresponding structures. The single-frame structure precise lifting and positioning equipment in the annular cable-supported grid structure described in the present invention, when the frame structure needs to be lifted, the frame structure will be fixed by ropes and connected to the tower crane 101 through the hanging column 102. At this time, the tower crane 101 can be started to complete the lifting work. However, since the drum of the traditional lifting equipment 1 is usually one or more cylindrical components with multiple ropes wound around it, when the drum rotates, the rope will be rolled up or released as the drum rotates, thereby realizing the lifting and lowering control of the hoisted object, and the pulley block is a complex mechanism composed of a series of pulleys, which is used to change the direction of the rope and distribute the weight of the hoisted object. These pulleys are usually fixed on a frame and work in conjunction with the drum to ensure that the rope can move smoothly. However, since the original intention of the design of the traditional lifting equipment 1 is to achieve the smooth lifting and lowering of the overall hoisting object, its drum and pulleys The group does not provide an independent mechanical structure for adjusting the length of a single rope, which means that during the hoisting process, if the rope length of a specific part needs to be adjusted to correct the tilt or offset of the hoisted object, the operator will not be able to directly achieve this function through the equipment itself. Instead, they need to rely on additional tools or methods to manually adjust the rope length, which not only increases the complexity and risk of the operation, but also affects the efficiency and accuracy of the hoisting operation. At this time, when the rotating gear 207 in the reciprocating adjustment mechanism 2 moves to the first winding drum 210, the rotating gear 207 will drive the first winding drum 210 to rotate, so that the rope on the first winding drum 210 can be wound and released, and the rope on the second winding drum 214 is in a fixed state at this time. The movement of the rotating gear 207 can be used to wind and release a single rope, thereby improving the efficiency and accuracy of the hoisting operation.

[0042] Embodiment 2

[0043] like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0044] like Figure 3 As shown, in this embodiment, an electric telescopic rod 215 is provided at one end of the linkage column 206 away from the motor 202, an inner cavity is opened inside the protection box 201, the motor 202 is fixedly connected to the side wall of the inner cavity of the protection box 201, the output end of the motor 202 is fixedly connected to the limiting column 203, a limiting groove 204 is opened inside the limiting column 203, and a guide block 205 is slidably connected inside the limiting groove 204.

[0045] As shown in FIG. 4 , in this embodiment, a linkage column 206 is fixedly connected to the side of the guide block 205 , a linkage column 206 is fixedly connected to the outer ring surface of the linkage column 206 , and a calibration rod 208 is fixedly connected to the outer ring surface of the rotating gear 207 .

[0046] Specifically, when the length of a single rope needs to be adjusted, the electric telescopic rod 215 fixed to the side wall of the inner cavity of the protection box 201 is started. At this time, the electric telescopic rod 215 will push the linkage column 206 to move in a straight line. Since the guide block 205 is fixed to the outer ring surface of the other end of the linkage column 206, and the guide block 205 slides in the limiting groove 204 opened inside the limiting column 203, when the electric telescopic rod 215 pushes the linkage column 206 to move, it will not affect the operation of the motor 202, and the linkage column 206 will drive the other components fixed thereto to move. When the side of the calibration rod 208 is against the side of the calibration hole 211, the output end of the electric telescopic rod 215 will stop moving, and the guide block 205 will slide to the end of the limiting groove 204 close to the motor 202. Through the setting of the electric telescopic rod 215 and the limiting groove 204, the linkage column 206 can be displaced in the horizontal direction.

[0047] like Figure 5 As shown, in this embodiment, the bottom of the inner cavity of the protection box 201 is fixedly connected to a support frame 209, and the side wall of the support frame 209 is rotatably connected to a first winding drum 210, a calibration hole 211 is opened on the side of the first winding drum 210, and a first gear ring 212 is fixedly connected to the side of the first winding drum 210, and a second winding drum 214 is rotatably connected to the side of the support frame 209, and a second gear ring 213 is fixedly connected to the side of the second winding drum 214, and the linkage column 206 is rotatably connected to the output end of the electric telescopic rod 215.

[0048] Specifically, when the linkage column 206 moves horizontally, it will synchronously drive the rotating gear 207 to move horizontally, and then drive the calibration rod 208 fixed to the outer ring surface of the rotating gear 207 to move synchronously. Since the length of the calibration rod 208 is greater than that of the rotating gear 207, it will enter the calibration hole 211 opened on the side of the first winding drum 210 before the side teeth of the rotating gear 207 mesh with the side teeth of the first gear ring 212. Since the calibration hole 211 is also of a double-sided inclined structure, when the calibration rod 208 is inserted into the calibration hole 211, the first winding drum 210 will rotate. At the same time, since the calibration hole 211 corresponds to the protruding part of the side teeth of the first gear ring 212, and the calibration rod 208 corresponds to the groove part on the side of the rotating gear 207, when the calibration rod 208 is inserted into the calibration hole 211, it can ensure that the teeth on the side of the rotating gear 207 are accurately docked with the teeth on the first gear ring 212. Through the cooperation of the calibration rod 208 and the calibration hole 211, when the side of the rotating gear 207 abuts against the side of the first gear ring 212 or the second gear ring 213, its teeth can remain engaged, thereby reducing the wear of the equipment. At the same time, through the reciprocating movement of the electric telescopic rod 215, the relationship between the rotating gear 207 and the first gear ring 212 or the second gear ring 213 can be adjusted, so as to achieve the purpose of adjusting a single rope, and thus improve the efficiency and accuracy of the hoisting operation.

[0049] As Figure 6 and Figure 7 shown, a linkage buckle mechanism 3 for fixing is arranged on the outer ring surface of the reciprocating adjustment mechanism 2 in this embodiment. The linkage buckle mechanism 3 includes a fixing ring 301. The rotating gear 207 is rotatably connected inside the fixing ring 301. One end of the fixing ring 301 is fixedly connected with a T-shaped rod 302. A first guide groove 303 is arranged at the bottom of the T-shaped rod 302. The first guide groove 303 is opened at the bottom of the rotating gear 207. The T-shaped rod 302 is slidably connected inside the first guide groove 303. The top of the T-shaped rod 302 is fixedly connected with an inclined rod 304. One end of the inclined rod 304 abuts against an inclined block 305. A second guide groove 306 is opened on the side wall of the support frame 209. The inclined block 305 is slidably connected inside the second guide groove 306. The top of the inclined block 305 is fixedly connected with a first spring 307. One end of the first spring 307 is fixedly connected to the top of the second guide groove 306.

[0050] As Figure 7 and Figure 8As shown, in this embodiment, the side wall of the oblique block 305 is fixedly connected with an elastic cable 308, and the other end of the elastic cable 308 is fixedly connected with a ratchet tooth 309, and the side wall of the ratchet tooth 309 is fixedly connected with a second spring 310, and the other end of the second spring 310 is fixedly connected with a fixed block 311, and the fixed block 311 is fixedly connected to the side wall of the support frame 209. A fixed column 312 is provided at one end of the ratchet tooth 309, and the fixed column 312 is fixedly connected to the side wall of the support frame 209. The ratchet tooth 309 is rotatably connected to the outer annular surface of the fixed column 312, and the ratchet tooth 309 is meshed with a ratchet ring 313, and the ratchet ring 313 is fixedly connected to the outer annular surface of the first winding drum 210.

[0051] Specifically, when the first spring 307 is displaced in the horizontal direction, it will synchronously drive the fixed ring 301 whose outer ring surface rotates to move synchronously, and at the same time drive the T-shaped rod 302 to move along the first guide groove 303 provided on the side wall of the support frame 209. At this time, when the rotating gear 207 rotates, the T-shaped rod 302 and the fixed ring 301 will not rotate due to the influence of the bottom protrusion of the T-shaped rod 302 and the first guide groove 303. When the T-shaped rod 302 moves, it will synchronously drive the oblique rod 304 fixed on the top thereof to move synchronously.

[0052] When the bottom of one end of the inclined rod 304 contacts the top of one end of the inclined block 305, the calibration rod 208 is just outside the calibration hole 211. When the inclined rod 304 continues to move, since the opposite ends of the inclined rod 304 and the inclined block 305 are both inclined structures, when the inclined rod 304 moves, the inclined block 305 will move upward along the guidance of the second guide groove 306. At this time, the first spring 307 is in a compressed state.

[0053] When the inclined block 305 moves upward, it will synchronously drive the elastic cable 308 fixed on its side to move. Since one end of the elastic cable 308 is fixed on the ratchet tooth 309, when the elastic cable 308 is pulled upward by the inclined block 305, the ratchet tooth 309 will rotate around the fixed column 312. At this time, the second spring 310 fixed on the side of the ratchet tooth 309 will be in a compressed state. When the ratchet tooth 309 rotates, it will leave the teeth on the outer ring surface of the ratchet ring 313. At this time, the calibration rod 208 fixed on the outer ring surface of the rotating gear 207 will enter the calibration hole 211, so that the calibration hole 211 and the calibration rod 208 are accurately aligned with the teeth. When the rotating gear 207 moves to the other side, it will drive the fixed ring 301 to move synchronously, and drive the inclined rod 304 to move during the movement. 304 does not abut against the inclined block 305, so the first spring 307 will reset, and at the same time drive the inclined block 305 to move downward along the guide of the second guide groove 306. At this time, the elastic cable 308 is in a relaxed state, and the second spring 310 will also reset due to the lack of external force, so at this time the ratchet teeth 309 will reset around the fixed column 312, thereby engaging with the teeth on the ratchet ring 313. Since the teeth on the outer ring surface of the ratchet ring 313 and the ratchet teeth 309 are both ratchet structures, the ratchet ring 313 will be stuck at this time. Since the ratchet ring 313 is fixed on the outer ring surface of one side of the first winding drum 210, the first winding drum 210 will also be stuck, thereby preventing the rope on the outer ring surface of the first winding drum 210 from being stretched by external force, thereby improving the safety of the equipment during construction.

[0054] Working principle: when the length of a single rope needs to be adjusted, the electric telescopic rod 215 fixed on the side wall of the inner cavity of the protection box 201 is started. At this time, the electric telescopic rod 215 will push the linkage column 206 to move in a straight line. Since the guide block 205 is fixed to the outer ring surface of the other end of the linkage column 206, and the guide block 205 slides in the limiting groove 204 opened inside the limiting column 203, when the electric telescopic rod 215 pushes the linkage column 206 to move, it will not affect the operation of the motor 202, and the linkage column 206 will drive the other components fixed thereto to move. When the side of the calibration rod 208 is against the side of the calibration hole 211, the output end of the electric telescopic rod 215 will stop moving, and the guide block 205 will slide to the end of the limiting groove 204 close to the motor 202. Through the setting of the electric telescopic rod 215 and the limiting groove 204, the linkage column 206 can be displaced in the horizontal direction.

[0055] When the linkage column 206 moves horizontally, it will synchronously drive the rotating gear 207 to move horizontally, and then drive the calibration rod 208 fixed on the outer ring surface of the rotating gear 207 to move synchronously. Since the length of the calibration rod 208 is greater than the length of the rotating gear 207, before the side teeth of the rotating gear 207 mesh with the side teeth of the first gear ring 212, the calibration rod 208 will enter the calibration hole 211 opened on the side of the first winding drum 210. Since the calibration hole 211 is also a double-sided oblique structure, the first winding drum 210 will rotate when the calibration rod 208 is inserted into the calibration hole 211. At the same time, since the calibration hole 211 corresponds to the protruding part of the side teeth of the first gear ring 212, and the calibration rod 208 corresponds The groove part on the side of the rotating gear 207, when the calibration rod 208 is inserted into the calibration hole 211, it can ensure that the teeth on the side of the rotating gear 207 are accurately docked with the teeth on the first gear ring 212. Through the cooperation of the calibration rod 208 and the calibration hole 211, when the side of the rotating gear 207 is against the side of the first gear ring 212 or the second gear ring 213, its teeth remain in a meshing state, thereby reducing the wear of the equipment. At the same time, the reciprocating motion of the electric telescopic rod 215 can adjust the relationship between the rotating gear 207 and the first gear ring 212 or the second gear ring 213, thereby achieving the purpose of adjusting a single rope, thereby improving the efficiency and accuracy of the lifting operation.

[0056] When the first spring 307 is displaced in the horizontal direction, it will synchronously drive the fixed ring 301 whose outer ring surface rotates to move synchronously, and at the same time drive the T-shaped rod 302 to move along the first guide groove 303 provided on the side wall of the support frame 209. At this time, when the rotating gear 207 rotates, the T-shaped rod 302 and the fixed ring 301 will not rotate due to the influence of the bottom protrusion of the T-shaped rod 302 and the first guide groove 303. When the T-shaped rod 302 moves, it will synchronously drive the oblique rod 304 fixed on the top thereof to move synchronously.

[0057] When the bottom of one end of the inclined rod 304 contacts the top of one end of the inclined block 305, the calibration rod 208 is just outside the calibration hole 211. When the inclined rod 304 continues to move, since the opposite ends of the inclined rod 304 and the inclined block 305 are both inclined structures, when the inclined rod 304 moves, the inclined block 305 will move upward along the guidance of the second guide groove 306. At this time, the first spring 307 is in a compressed state.

[0058] When the inclined block 305 moves upward, it will synchronously drive the elastic cable 308 fixed on its side to move. Since one end of the elastic cable 308 is fixed on the ratchet tooth 309, when the elastic cable 308 is pulled upward by the inclined block 305, the ratchet tooth 309 will rotate around the fixed column 312. At this time, the second spring 310 fixed on the side of the ratchet tooth 309 will be in a compressed state. When the ratchet tooth 309 rotates, it will leave the teeth on the outer ring surface of the ratchet ring 313. At this time, the calibration rod 208 fixed on the outer ring surface of the rotating gear 207 will enter the calibration hole 211, so that the calibration hole 211 and the calibration rod 208 are accurately aligned with the teeth. When the rotating gear 207 moves to the other side, it will drive the fixed ring 301 to move synchronously, and drive the inclined rod 304 to move during the movement. 304 does not abut against the inclined block 305, so the first spring 307 will reset, and at the same time drive the inclined block 305 to move downward along the guide of the second guide groove 306. At this time, the elastic cable 308 is in a relaxed state, and the second spring 310 will also reset due to the lack of external force, so at this time the ratchet teeth 309 will reset around the fixed column 312, thereby engaging with the teeth on the ratchet ring 313. Since the teeth on the outer ring surface of the ratchet ring 313 and the ratchet teeth 309 are both ratchet structures, the ratchet ring 313 will be stuck at this time. Since the ratchet ring 313 is fixed on the outer ring surface of one side of the first winding drum 210, the first winding drum 210 will also be stuck, thereby preventing the rope on the outer ring surface of the first winding drum 210 from being stretched by external force, thereby improving the safety of the equipment during construction.
