Description

Technical Field

[0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a lifting device used in bridge engineering construction. Background Art

[0002] In modern bridge construction, lifting equipment plays a vital role. It is not only required to have efficient and safe operating capabilities, but also must adapt to complex and changing construction environments and operating requirements. As a key component in lifting equipment, the performance of wire rope directly affects the safety and efficiency of lifting operations. For example, the Chinese patent application with publication number: CN118723785A provides a crane for bridge deck laying and a method of using it. Through the setting of an anti-wear device, the rubber roller and the sponge roller guide the movement of the wire rope to ensure that the wire rope moves along a predetermined path when the wire rope is retracted and released, thereby avoiding the problem of friction between the wire rope and the bracket or other metal parts of the wire rope retracting and releasing device when the wire rope shakes, causing wear and damage to the wire rope.

[0003] There are still some problems with the use of lifting equipment such as this. First, during long-term use, due to friction and wear, the wire rope needs to be lubricated regularly to reduce the friction coefficient and extend its service life. For example, although the above-mentioned lifting equipment has an automatic lubrication function, it lacks an intelligent control mechanism and cannot accurately lubricate according to the actual wear and lubrication needs of the wire rope. Excessive lubrication not only wastes resources, but may also cause the surface of the wire rope to become sticky and slippery due to grease accumulation, increasing safety hazards.

[0004] Secondly, in bridge construction, lifting equipment often needs to face hoisting operations at different heights, which requires the wire rope retraction path to be flexibly adjusted to adapt to changing construction scenarios. The above-mentioned lifting equipment uses a fixed wire rope retraction path, relying on the autonomous movement of the wire rope during retraction to control subsequent operations, and cannot be dynamically adjusted according to actual needs. This not only limits the flexibility of lifting operations, but may also cause increased wear of the wire rope due to improper paths, and even cause safety accidents.

[0005] Finally, bridge construction sites are often located in open areas with strong winds. Hoisted objects are prone to shaking under the action of wind loads, which not only affects construction accuracy but may also cause damage to lifting equipment and surrounding structures.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0044] Please see attached Figures 1 to 13 As shown, this embodiment provides a lifting device for bridge engineering construction, including a transport vehicle 10, and a main body component 20 is fixedly connected to the top of the transport vehicle 10;

[0045] A main body component 20, the main body component 20 includes a frame component 21, and a buffer component 22 is disposed at the bottom of the frame component 21;

[0046] The regulating component 30 includes a movable component 31 disposed in the inner cavity of the frame component 21, a storage component 32 is disposed in the inner cavity of the movable component 31, an opening and closing component 33 is disposed in the inner cavity of the storage component 32, and a driving component 34 is disposed at the bottom of the movable component 31;

[0047] Among them, the transport vehicle 10 is used to transport the entire device, after the frame assembly 21 hangs the object, the movable assembly 31 is used to control the path of cable recovery;

[0048] When the cable needs to be maintained, the driving component 34 moves downward along the inner cavity of the movable component 31 and contacts the opening and closing component 33. When the movable component 31 moves, the opening and closing component 33 is driven to move on the bottom surface of the driving component 34, controlling the storage component 32 to open and close continuously, and applying maintenance to the cable through the storage component 32.

[0049] It should be noted that the transport vehicle 10 is provided with a telescopic arm and a matching driving component.

[0050] In this embodiment, when performing lifting operations, the driving part of the frame assembly 21 performs lifting and hoisting. If the object and the cable shake, the buffer assembly 22 can absorb the shaking force and apply a reverse force to offset it, thereby weakening the shaking force. In daily use, the moving part of the movable assembly 31 will continue to move to adjust the cable retraction path to ensure stability and safety. When the cable needs to be maintained, the moving part of the driving assembly 34 will drop and contact the opening and closing assembly 33, and when the movable assembly 31 moves, it will drive the opening and closing assembly 33 to move on the bottom surface of the driving assembly 34, so that the opening and closing assembly 33 is continuously raised and lowered, and the storage assembly 32 is continuously opened, and the stored liquid for lubricating the cable is intermittently discharged, and the cable is coated through the coating part of the storage assembly 32. When maintenance is not required, it is only necessary to raise the lifting part of the driving assembly 34 and disconnect the contact with the opening and closing assembly 33.

[0051] Secondly, please refer again to Figures 1 to 5 The frame assembly 21 includes a fixed frame 211 installed on the top of the transport vehicle 10, a winch 212 is installed on the top of the inner cavity of the fixed frame 211, a first motor 213 is fixedly connected to the top of the left side of the fixed frame 211, the output shaft of the first motor 213 is fixedly connected to the rotating shaft of the winch 212, a steel wire rope 214 is fixedly connected to the inner cavity of the winch 212, the bottom end of the steel wire rope 214 passes through the fixed frame 211, and the bottom end of the steel wire rope 214 is fixedly connected to a hook 215, the bottom of the inner cavity of the fixed frame 211 is hinged with a limiting wheel 216, and the outer ring of the steel wire rope 214 is rollingly connected to the inner cavity of the limiting wheel 216;

[0052] The buffer assembly 22 includes a support frame 221 fixedly connected to the bottom surface of the fixed frame 211, a slider 222 is slidably connected to the inner cavity of the support frame 221, a spring 223 is fixedly connected to the middle of the slider 222, the other end of the spring 223 is fixedly connected to the middle of the inner cavity of the support frame 221, and a rubber skin 224 is fixedly connected to the side of the slider 222 facing the center of the support frame 221;

[0053] The buffer assembly 22 is provided with four groups distributed on the bottom surface of the fixed frame 211 , and the steel wire rope 214 is movably sleeved on the middle part of the plurality of groups of sliders 222 .

[0054] It should be noted that there are eight groups of sliders 222 and rubber skins 224, which are evenly distributed in the inner cavity of the support frame 221, so that no matter which direction the wire rope 214 swings, a reaction force can be applied to weaken the swinging force.

[0055] In this embodiment, in daily use, the object is hung on the hook 215. After the first motor 213 is started, the winch 212 will drive the hook 215 to rise or fall through the wire rope 214 to achieve the lifting of the object. When the wire rope 214 swings in the air, it will push the slider 222 to slide in the inner cavity of the support frame 221. At this time, the spring 223 shrinks and rebounds, exerting a reverse force on the wire rope 214, and the rubber skin 224 generates resistance to the swing through friction, thereby reducing the swing amplitude and ensuring the stability of the lifting process. In addition, the setting of the limiting wheel 216 ensures the correct guidance of the wire rope 214 in the inner cavity, preventing the disorder and wear of the wire rope 214. In actual operation, by adjusting the speed and direction of the first motor 213, the lifting speed and position of the object can be accurately controlled to meet the needs of different construction scenes.

[0056] Secondly, please refer again to Figure 4 and Figure 6 The movable component 31 includes a double-track frame 311 fixedly connected to the middle part of the inner cavity of the fixed frame 211, the inner cavity of the double-track frame 311 is slidably connected to a sliding frame 312, a second motor 313 is fixedly connected to the middle part of the left side of the fixed frame 211, a bidirectional screw rod 314 is fixedly connected to the output shaft of the second motor 313, the bidirectional screw rod 314 is rotatably connected to the inner cavity of the double-track frame 311, the middle section outer ring of the bidirectional screw rod 314 is threadedly connected to the middle part of the sliding frame 312, the inner cavity of the sliding frame 312 is hinged with a limiting wheel 2 315, and the outer ring of the wire rope 214 is rollingly connected to the outer ring of the limiting wheel 2 315.

[0057] It should be noted that the portions of the front and rear sides of the sliding frame 312 that are in contact with the double-track frame 311 are both provided with stop plates that are higher than the sliding frame 312 , in order to improve the stability of the movement of the sliding frame 312 ;

[0058] There are four groups of limiting wheels 315, which are symmetrically distributed in the inner cavity of the sliding frame 312, so as to make the wire rope 214 in a vertical state in the inner cavity of the sliding frame 312, which is convenient for subsequent oiling and maintenance.

[0059] In this embodiment, in daily use, the second motor 313 drives the bidirectional screw rod 314 to rotate, thereby driving the sliding frame 312 to slide along the inner cavity of the double-track frame 311, thereby controlling the recovery path of the wire rope 214.

[0060] Secondly, please refer again to Figures 6 to 13The storage assembly 32 includes a storage tank 321 fixedly connected to the outside of the sliding frame 312, a drainage channel 322 is provided at the bottom of the storage tank 321, and the drainage channel 322 is connected to the storage tank 321 and the inner cavity of the sliding frame 312, and a smear wheel 323 is hingedly connected to the inner cavity of the sliding frame 312, and an anti-slip strip 324 is fixedly connected to the outer ring of the smear wheel 323, and the smear wheel 323 is arranged at the outlet of the drainage channel 322;

[0061] The opening and closing assembly 33 includes a lifting rod 331 slidably connected to the middle of the inner cavity of the storage tank 321, a sealing plug 332 is fixedly connected to the top of the lifting rod 331, and the sealing plug 332 is slidably connected to the middle of the inner cavity of the storage tank 321. The front and rear ends of the bottom of the lifting rod 331 are fixedly connected to a long frame 333, and the front and rear sides of the bottom of the inner cavity of the storage tank 321 are rotatably connected to a rotating rod 334. One end of the rotating rod 334 located in the inner cavity of the storage tank 321 is fixedly connected to a push rod 335, and the push rod 335 is fixedly connected to the push rod 335. The outer ring of the rotating rod 334 is movably sleeved in the inner cavity of the long frame 333, and the end of the rotating rod 334 located outside the storage tank 321 is fixedly connected to the first gear 336, the outer ring of the first gear 336 is meshed with a chain 337, the inner ring of the bottom end of the chain 337 is meshed with a second gear 338, and the middle outer ring of the second gear 338 is fixedly connected to a connecting rod 339, which is rotatably connected to the outer bottom of the sliding frame 312, and the outer top of the connecting rod 339 is fixedly connected to the third gear 3310;

[0062] The driving assembly 34 includes a lifting plate 341 slidably connected to the bottom of the inner cavity of the double-track frame 311, electric push rods 342 are fixedly installed on the left and right sides of the inner cavity of the double-track frame 311, and the bottom output ends of the electric push rods 342 are fixedly connected to the top surface of the lifting plate 341, and the bottom surface of the lifting plate 341 is fixedly connected to a rack 343, and the outer ring of the third gear 3310 is meshed with the bottom surface of the rack 343;

[0063] There are two groups of rotating rods 334 and first gears 336 , which are distributed at the front and rear sides of the bottom of the inner cavity of the storage tank 321 , and two groups of pushing rods 335 are connected to the two groups of long frames 333 .

[0064] It should be noted that the lifting rod 331 is a quadrilateral long rod, which is intended to prevent the lifting rod 331 from swinging left and right during the lifting process, thereby affecting the connection between the long frame 333 and the push rod 335;

[0065] A small flow detector (not shown in the figure) is provided at the outlet of the storage tank 321, which is designed to control the sealing plug 332 to descend before the steel wire rope 214 is maintained, so as to seal the bottom of the storage tank 321. At this time, the flow detector is used to detect whether the storage tank 321 is in a sealed state, so as to prevent the lubricating oil from flowing out all the time and affecting the normal use of the steel wire rope 214.

[0066] The anti-slip strip 324 is an arc-shaped rubber strip, and the inner diameter of the anti-slip strip 324 is smaller than the steel wire rope 214, so that when the steel wire rope 214 moves, the anti-slip strip 324 and the coating wheel 323 can be driven to rotate.

[0067] In this embodiment, when the steel wire rope 214 needs to be maintained, the electric push rod 342 pushes the lifting plate 341 downward, so that the rack 343 meshes with the third gear 3310, and when the sliding frame 312 moves, it drives the third gear 3310 to roll on the bottom surface of the rack 343, and the third gear 3310 drives the linkage rod 339 and the second gear 338 to rotate, thereby driving the chain 337 and the first gear 336 to rotate. At this time, the first gear 336 drives the push rod 335 to rotate, so that the long frame 333 slides up and down, thereby pushing the lifting rod 331 to move up and down, so that the sealing plug 332 is separated from the bottom of the storage tank 321, and the lubricating oil flows out through the drainage channel 322 and is applied to the coating wheel 323. When the steel wire rope 214 moves, it drives the coating wheel 323 and the anti-skid strip 324 to rotate, so that the lubricating oil can be evenly applied to the surface of the steel wire rope 214, ensuring the lubrication and anti-corrosion effect of the steel wire rope 214. After the steel wire rope 214 is maintained and no lubricating oil is needed, the lifting plate 341 only needs to be raised to separate the rack 343 from the third gear 3310 .

[0068] The working principle of the present invention is as follows: in daily use, an object is hung on the hook 215. After the first motor 213 is started, the winch 212 drives the hook 215 to rise or fall through the wire rope 214 to achieve the hoisting of the object. When collecting the rope, the second motor 313 drives the bidirectional screw 314 to rotate, thereby driving the sliding frame 312 to slide along the inner cavity of the double-track frame 311, thereby controlling the recovery path of the wire rope 214. When the wire rope 214 swings in the air, it pushes the slider 222 to slide in the inner cavity of the support frame 221. At this time, the spring 223 contracts and rebounds, exerting a reverse force on the wire rope 214, and the rubber skin 224 generates resistance to the swing through friction, thereby reducing the swing amplitude. When the steel wire rope 214 needs to be maintained, the electric push rod 342 pushes the lifting plate 341 downward, so that the rack 343 meshes with the third gear 3310, and when the sliding frame 312 moves, it drives the third gear 3310 to roll on the bottom surface of the rack 343, drives the linkage rod 339 and the second gear 338 to rotate, and then drives the chain 337 and the first gear 336 to rotate, and drives the push rod 335 to rotate, so that the long frame 333 and the lifting rod 331 move up and down, so that the sealing plug 332 is separated from the bottom of the storage tank 321, and the lubricating oil flows out through the drainage channel 322 and is applied to the coating wheel 323. When the steel wire rope 214 moves, it drives the coating wheel 323 and the anti-skid strip 324 to rotate, and the lubricating oil can be evenly applied to the surface of the steel wire rope 214, ensuring the lubrication and anti-corrosion effect of the steel wire rope 214. After the maintenance of the steel wire rope 214 is completed, it is only necessary to raise the lifting plate 341 to separate the rack 343 from the third gear 3310 .

[0069] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
