Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and more specifically, to a split-type bridge damper hoisting fixture that can be quickly disassembled and assembled. Background Technology

[0002] A bridge damper is a bridge component that reduces vibration and dissipates energy by providing resistance to motion. In bridge engineering, bridge dampers are typically used to reduce bridge vibrations under wind loads, earthquakes, or other dynamic loads, thereby improving bridge safety and comfort. They are generally installed at the bottom of the box girder and connected to the piers. Conventional installation methods include winch lifting, electric hoist lifting, and truck crane hoisting. However, due to limitations in installation height, working space, and on-site construction environment, these methods all present challenges in operation and require stringent construction conditions. The main problems are as follows: 1. Traditional installation methods using electric hoists are limited by the limited rope capacity of electric hoists, making them unsuitable for high-altitude installations. Furthermore, it requires ensuring unobstructed access in the vertical lifting direction. In new bridge construction, the installation of bridge dampers often occurs after the bridge cables are tensioned, before the temporary supports of the pipe piles around the piers are removed. Therefore, it is difficult to guarantee that there are no obstructions below the installation location of the bridge damper during actual operation.

[0003] 2. Traditional winch lifting and installation methods have high requirements for the layout of guide pulley blocks and are relatively complicated in actual operation. When working in a confined space, it is impossible to move the hoisted object in the horizontal direction. Therefore, if there are obstacles in the vertical direction of the bridge damper installation position, it is impossible to hoist it to the installation position, and a secondary hoisting scheme must be considered.

[0004] 3. Traditional truck crane hoisting methods have strict requirements on the hoisting site. When the bridge piers are located in water and truck cranes cannot reach them, the above two hoisting methods must be used. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a split-type bridge damper hoisting fixture that can be quickly disassembled and assembled, which can effectively realize the hoisting and installation of bridge dampers, and leave more operating space for the hoisting and installation of bridge dampers, making the installation of bridge dampers simpler, greatly improving efficiency and reducing installation costs compared with the prior art; The solution adopted by this utility model to solve the technical problem is: A split-type bridge damper hoisting fixture that can be quickly disassembled includes a sliding rail installed at the bottom of a box girder, a sliding load-bearing component that slides with the sliding rail, a hoisting lifting component installed on the sliding load-bearing component for hoisting the bridge damper, a lifting component installed on the sliding rail and used in conjunction with the hoisting lifting component and the sliding load-bearing component respectively, and a horizontal drive component installed on the sliding rail and used in conjunction with the sliding load-bearing component.

[0006] In some possible implementations, the horizontal drive assembly includes a rope take-up and release assembly with a traction rope disposed on the same side as the lifting assembly, and a guide wheel installed on the side of the sliding track away from the lifting assembly; one end of the traction rope passes around the guide wheel and is connected to the sliding load-bearing assembly.

[0007] In some possible implementations, the hoisting assembly includes a fixed pulley on a sliding load-bearing assembly arranged on one side along the length of the sliding track, a lifting component for hoisting the bridge damper, and a hoisting rope that is driven and engaged with the lifting component and the fixed pulley respectively and has one end connected to the sliding load-bearing assembly; the other end of the hoisting rope is connected to a lifting assembly. The connection point between the lifting rope and the sliding load-bearing component is located on the side near the guide wheel.

[0008] In some possible implementations, the lifting component includes a lifting seat and a movable pulley disposed on the lifting seat and used in conjunction with a fixed pulley and a lifting rope.

[0009] In some possible implementations, the sliding load-bearing assembly includes a slide that slides in conjunction with a sliding track and a rope locker mounted on the side of the slide near the lifting assembly and used in conjunction with the lifting rope.

[0010] In some possible implementations, a monitoring component is provided between the rope locker and the lifting assembly for monitoring the loosening of the lifting rope between the rope locker and the lifting assembly; A monitoring component two for monitoring the positional relationship between the lifting component and the slide is provided on the slide.

[0011] In some possible implementations, the first monitoring component is a laser position sensor; the second monitoring component is a tension tester.

[0012] In some possible implementations, the slide includes a clamping plate and rollers mounted on the clamping plate and slidably engaged with a sliding track; the fixed pulley is mounted on the clamping plate.

[0013] In some possible implementations, the lifting assembly is a hoist and the rope winding assembly is a manual hoist.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared with the existing technology that uses winch hoisting, this utility model eliminates the need for the complex system layout and installation space requirements of winch hoisting, reducing the number of on-site operators. When using this utility model, operators work at the installation point of the bridge damper. At the same time, this utility model does not require the extensive construction and welding of winches and guide systems as winch hoisting. This tooling structure is lightweight and simple, can be installed and used immediately, and can be quickly dismantled after construction. All components can be moved manually, making installation and dismantling more convenient and reducing construction costs. Compared with the existing electric hoist lifting method, this utility model does not require rope laying and drum rope storage, leaving more operable space for the limited space operation of bridge damper installation, making bridge damper installation simpler. This utility model can be arranged arbitrarily according to the installation location and on-site working conditions, and can realize the horizontal movement of the bridge damper without the need for secondary transfer and transportation during hoisting. It can meet the hoisting construction operation when there are obstacles below the installation location in a limited working space. Compared with the existing technology that uses truck cranes for hoisting, this utility model has no site requirements and can be applied to hoisting operations in limited spaces.

[0017] The present invention will now be described in detail.

[0018] like Figures 1-5 As shown: A split-type bridge damper hoisting fixture that can be quickly disassembled and assembled includes a sliding rail 1 that can be detachably installed at the bottom of the box girder, a sliding load-bearing component 2 that slides with the sliding rail 1, a hoisting lifting component 3 installed on the sliding load-bearing component 2 and used for hoisting the bridge damper 10, a lifting component 4 installed on the sliding rail 1 and used in conjunction with the hoisting lifting component 3 and the sliding load-bearing component 2 respectively, and a horizontal drive component 5 installed on the sliding rail and used in conjunction with the sliding load-bearing component 2. Furthermore, a lifting lug 11 for connecting the box girder is provided at the top of the sliding track 1, and the sliding track 1 is detachably connected to the bottom of the box girder through the lifting lug 11; In use, the horizontal drive component 5 is used to control the sliding load-bearing component 2 and the hoisting component 3 to move directly above the hoisting point of the bridge damper 10. Secondly, by controlling the lifting component 4 to lower the hoisting component 3 to the side of the bridge damper 10, the hoisting component 3 is connected and fixed to the bridge damper 10. Subsequently, the hoisting assembly 3 and the bridge damper 10 are lifted together by the lifting assembly 4 until they reach the highest point and then the lifting stops. Then, the lifting component 4 controls the sliding load-bearing component 2, the hoisting component 3 and the bridge damper 10 to move along the length of the sliding track 1 until they move to the installation point and the hoisting is completed, then the bridge damper 10 can be installed. Specifically, the horizontal drive component 5 controls the sliding load-bearing component 2 and the hoisting component 3 to move away from the lifting component 4 and move directly above the bridge damper 10; when the bridge damper 10 is hoisted to the highest point, the lifting component 4 will move the whole formed by the sliding load-bearing component 2, the hoisting component 3 and the bridge damper 10 along the length of the sliding track 1 and towards the side closer to the lifting component 4 until it reaches the installation point.

[0019] In some possible implementations, in order to effectively control the movement of the sliding load-bearing component 2 along the length of the sliding track 1 away from the lifting component 4 via the horizontal drive component 5, so that it can move directly above the hoisting point; the horizontal drive component 5 includes a rope winding and unwinding component 51 disposed on the same side as the lifting component 4 and having a traction rope 511, and a guide wheel 52 installed on the side of the sliding track 1 away from the lifting component 4; one end of the traction rope 511 passes around the guide wheel 52 and is connected to the sliding load-bearing component 2; the rope winding and unwinding component 51 is a manual hoist; Specifically, the guide wheel 52 is fixed by a fixed seat installed on the side of the sliding track 1 away from the lifting assembly 4; the traction rope 511 is set along the length of the sliding track 1, and passes around the outside of the guide wheel 52 and is connected at one end to the traction fixing point 53 set on the sliding load-bearing assembly 2. The manual hoist is installed at the bottom of the sliding track 1 near the lifting assembly 4. The hook of the manual hoist is connected to one end of the traction rope 511. In use, the chain connected to the hook is tightened to make the chain and traction rope 511 taut. In the taut state, the chain and traction rope 511 are set along the length of the sliding track 1. During the tightening process, the manual hoist drives the traction rope 511 to move to the side of the manual hoist, thereby driving the sliding load-bearing assembly 2 to move away from the lifting assembly 4. When it reaches directly above the lifting point, the manual hoist stops working. Then, the lifting assembly 4 controls the lifting assembly 3 to move closer to the bridge damper 10 and connect the two.

[0020] In some possible implementations, the hoisting assembly 3 includes a fixed pulley 31 on a sliding load-bearing assembly 2 arranged along one side of the length direction of the sliding track 1, a lifting member 32 for hoisting the bridge damper 10, and a lifting rope 33 that is driven and cooperates with the lifting member 32 and the fixed pulley 31 respectively and is connected at one end to the sliding load-bearing assembly 2; the other end of the lifting rope 33 is connected to the lifting assembly 4; the lifting member 32 includes a hoisting seat and a movable pulley 321 arranged on the hoisting seat and used in cooperation with the fixed pulley 31 and the lifting rope 33; The connection point between the lifting rope 33 and the sliding load-bearing component 2 is located on the side near the guide wheel 52; like Figure 3 As shown, there are two sets of fixed pulleys 31, with their axes perpendicular to the length direction of the sliding track 1 and arranged horizontally. Two sets of movable pulleys 321 are also installed on the hoisting seat. The axes of the two sets of fixed pulleys 31 and the two sets of movable pulleys 321 are staggered. For example, the movable pulley 321 closer to the lifting component 4 is located between the two sets of fixed pulleys 31, and the fixed pulley 31 closer to the guide wheel 52 is located between the two sets of movable pulleys 321. One end of the lifting rope 33 is connected to the lifting component 4, and then its other end is arranged along the length direction of the sliding track 1, passing over the fixed pulley 31 closer to the lifting component 4, the movable pulley 321 closer to the lifting component 4, the fixed pulley 31 farther from the lifting component 4, and the movable pulley 321 farther from the lifting component 4, and connecting to the lifting connection point 34 located on the sliding track 1. The lifting connection point 34 is located on the side of the traction fixing point 53 away from the guide wheel 52.

[0021] In some possible implementations, the sliding load-bearing assembly 2 includes a slide 21 that slides with the sliding rail 1 and a rope locker 22 installed on the slide 21 near the lifting assembly 4 and used in conjunction with the lifting rope 33; the slide 21 includes a clamping plate and rollers installed on the clamping plate and sliding with the sliding rail 1; the fixed pulley 31 is installed on the clamping plate.

[0022] The rope locker 22 is used to fix the lifting rope 33; specifically, when the bridge damper 10 is raised to the highest point, the rope locker 22 will lock the lifting rope 33, so that the sliding load-bearing component 2, the hoisting component 3 and the bridge damper 10 form a whole; that is, the whole can be controlled to move along the length of the sliding track 1 and toward the lifting component 4 in the subsequent control, so that the bridge damper 10 can be moved to the installation point.

[0023] In some possible implementations, a monitoring component 6 is provided between the rope locker 22 and the lifting assembly 4 to monitor the loosening of the lifting rope 33 between the rope locker 22 and the lifting assembly 4; Specifically, after the bridge damper 10 moves along the length of the sliding track 1 to the installation point under the control of the lifting assembly 4, the position of the bridge damper 10 needs to be finely adjusted when connecting it to the bottom of the box girder, since the bridge damper 10 is connected to the bottom of the box girder by bolting or other means. Therefore, after the bridge damper 10 moves to the installation point, the lifting assembly 4 needs to lower a small section of the lifting rope 33. After it is below, when the monitoring assembly 6 senses that the steel wire rope from the rope locker 22 to the lifting assembly 4 is loose, the rope locker 22 unlocks and no longer locks the lifting rope 33, and the bridge damper 10 can be installed.

[0024] A monitoring component 2 7 is provided on the slide table 21 for monitoring the positional relationship between the lifting component 32 and the slide table 21; Specifically, when the lifting component 4 lifts the bridge damper 10, the monitoring component 2 7 will monitor whether the lifting component 32 has moved to the highest point. When it moves to the highest point, the rope locker 22 will lock the rope. Furthermore, monitoring component 6 can be a tension tester; monitoring component 7 can be a laser position sensor.

[0025] In some possible implementations, the lifting assembly 4 is a hoist, and the rope winding and unwinding assembly 51 is a manual hoist; the hoist, manual hoist, and rope locker 22 are existing technologies, and the improvements of this utility model are not here, so they will not be described in detail.

[0026] on the other hand: This utility model provides a hoisting method for the split-type quick-disassembly and assembly hoisting fixture of the bridge damper 10 described above, specifically including the following steps: Step S1: Assemble the bridge damper 10 hoisting fixture and install the bridge damper 10 hoisting fixture at the bottom of the box girder; Step S2: The horizontal drive assembly 5 tightens the traction rope 511 to control the sliding load-bearing assembly 2 to move along the length of the sliding track 1 and away from the lifting assembly 4, so that the hoisting lifting assembly 3 is located directly above the hoisting point of the bridge damper 10 and the traction rope 511 used to connect the horizontal drive assembly 5 and the sliding load-bearing assembly 2 is taut. Step S3: The lifting assembly 4 controls the hoisting and lifting assembly 3 to move vertically and connect with the bridge damper 10, and lifts the bridge damper 10 through the lifting assembly 4; Step S4: When the bridge damper 10 is raised to the highest point, stop the lifting and lock the ropes connected to the lifting assembly 4 and the hoisting assembly 3 by using the lifting rope locker 22; Step S5: The manual hoist controls the traction rope 511 to loosen, while the lifting assembly 4 controls the overall structure formed by the bridge damper 10, the hoisting assembly 3, the sliding load-bearing assembly 2, and the rope locker 22 to move towards the side closer to the lifting assembly 4 until it moves to the installation point of the bridge damper 10. Step S6: After the bridge damper 10 is moved to the installation point, it will be connected to the box girder by bolting, and the hole position will be aligned and fine-tuned. In this regard, the lifting assembly 4 lowers a short section of the lifting rope 33. When the monitoring assembly 6 senses that the wire rope from the rope locker 22 to the hoist is loose, the rope locker 22 can be triggered to unlock, and the bridge damper 10 can be installed. Specifically, the length of the lowered lifting rope 33 can be determined according to the site requirements.

[0027] This utility model uses the lifting component 4 as the main lifting power, which is applicable to hoisting operations at various heights. It does not need to consider issues such as rope capacity, rope arrangement, wire rope guidance, and interference with other working surfaces. The sliding load-bearing component 2 and the hoisting lifting component 3 can change the single-rate wire rope of the lifting component to a multi-rate wire rope according to the weight of the hoisting component to meet the hoisting needs. This utility model can be quickly assembled and disassembled in the limited space between the bottom of the beam and the pier. The layout is relatively simple and easy to operate. Only two fixed lifting point plates and lifting lugs need to be welded on site to achieve connection. The direction of the lifting lugs needs to be determined according to the translation direction of the bridge damper 10. The tooling layout and damper hoisting operation can be completed. The hoisting direction can be adjusted arbitrarily to completely avoid obstacles below the hoisting. This utility model, through the horizontal drive component 5, can vertically lift the bridge damper 10 and move it according to the installation direction of the bridge damper 10, which can meet the needs of hoisting construction operations with obstacles below the installation position in a limited working space.

[0028] This utility model is lightweight, can be quickly assembled and disassembled, and can be reused multiple times for different hoisting conditions.

[0029] In this utility model, the hoist is installed and fixed at the end of the sliding track, avoiding the traditional method of hoisting components on the wire rope. The installation of the bridge damper 10 is already carried out in a limited space. This method leaves more operational space for the hoisting and installation of the bridge damper 10, making the installation of the bridge damper 10 simpler.

[0030] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
