Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge engineering, and more particularly to a split type bridge damper hoisting tool and method capable of being quickly disassembled. BACKGROUND

[0002] The bridge damper is a bridge component that can achieve vibration reduction and energy dissipation by providing movement resistance and consuming movement energy. In bridge engineering, the bridge damper is usually used to reduce the vibration of the bridge under the action of wind load, earthquake or other dynamic load, so as to improve the safety and comfort of the bridge. The bridge damper is generally installed at the bottom of the box girder and connected with the pier. The conventional installation methods include the hoisting installation method of the winch, the hoisting installation method of the electric hoist and the hoisting method of the truck crane. However, the above installation methods have the problems of great operation difficulty and strict construction conditions due to the limitation of installation height, operation space and site construction environment. The main problems are as follows: 1. The conventional hoisting installation method of the electric hoist cannot meet the construction requirements under the condition of high hoisting height because of the limited rope of the electric hoist. In addition, it is necessary to ensure that there is no obstacle interference in the vertical lifting direction. In the process of new bridge construction, the bridge damper installation node needs to be performed after the completion of the bridge cable tensioning. Therefore, it is difficult to ensure that there is no obstacle below the installation position of the bridge damper in the actual operation process because the temporary support of the pipe pile around the pier has not been removed.

[0003] 2. The conventional hoisting installation method of the winch has high requirements for the layout of the guide pulley block and is complex in actual operation. When operating in a limited space, the hoisted object cannot move in the horizontal direction. Therefore, when there is an obstacle in the vertical direction of the installation position of the bridge damper, the bridge damper cannot be hoisted to the installation position. It is also necessary to consider the secondary lifting scheme.

[0004] 3. The conventional hoisting method of the truck crane has strict requirements for the hoisting site. When the pier is located in the water area, the truck crane cannot be used, and the above two hoisting methods need to be used. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a split type bridge damper hoisting tool and method capable of being quickly disassembled, which can effectively realize the hoisting and installation of the bridge damper, leave more operable space for the hoisting and installation of the bridge damper, make the installation of the bridge damper more simple, greatly improve the efficiency compared with the prior art, and reduce the installation cost.

[0018] The present application will be described in detail below.

[0019] As Figures 1-5 shown: A split type bridge damper hoisting tool capable of being quickly disassembled, comprising a sliding track 1 detachably mounted at the bottom of a box girder, a sliding load-bearing assembly 2 in sliding cooperation with the sliding track 1, a hoisting lifting assembly 3 mounted on the sliding load-bearing assembly 2 and used for hoisting a bridge damper 10, a lifting assembly 4 mounted on the sliding track 1 and used in cooperation with the hoisting lifting assembly 3 and the sliding load-bearing assembly 2 respectively, and a horizontal driving assembly 5 mounted on the sliding track and used in cooperation with the sliding load-bearing assembly 2; Further, a box girder connecting lifting lug 11 is arranged at the top of the sliding track 1, and the detachable connection of the sliding track 1 and the bottom of the box girder is realized through the lifting lug 11; In use, first, the sliding load-bearing assembly 2 and the hoisting lifting assembly 3 are controlled to move to the exact position above the hoisting point of the bridge damper 10 through the horizontal driving assembly 5; Secondly, the hoisting lifting assembly 3 is controlled to descend to one side of the bridge damper 10 through the lifting assembly 4, and the hoisting lifting assembly 3 is connected and fixed with the bridge damper 10; Subsequently, the whole formed by the hoisting lifting assembly 3 and the bridge damper 10 is lifted through the lifting assembly 4 until the lifting is stopped after reaching the highest point; Then, the lifting assembly 4 controls the whole formed by the sliding load-bearing assembly 2, the hoisting and lifting assembly 3 and the bridge damper 10 to move along the length direction of the sliding rail 1 until it reaches the installation point, and the hoisting and lifting is completed, and the installation of the bridge damper 10 can be performed. Specifically, the horizontal driving assembly 5 controls the sliding load-bearing assembly 2 and the hoisting and lifting assembly 3 to move away from the lifting assembly 4 and to the position right above the bridge damper 10; when the bridge damper 10 is hoisted to the highest point, the lifting assembly 4 controls the whole formed by the sliding load-bearing assembly 2, the hoisting and lifting assembly 3 and the bridge damper 10 to move along the length direction of the sliding rail 1 and to the side close to the lifting assembly 4 until it reaches the installation point.

[0020] In some possible embodiments, in order to effectively control the sliding load-bearing assembly 2 to move away from the lifting assembly 4 along the length direction of the sliding rail 1 by the horizontal driving assembly 5 and to the position right above the hoisting point, the horizontal driving assembly 5 comprises a winding and unwinding rope assembly 51 provided on the same side of the lifting assembly 4 and having a traction rope 511, and a guide wheel 52 installed on the side of the sliding rail 1 away from the lifting assembly 4; one end of the traction rope 511 is wound around the guide wheel 52 and connected with the sliding load-bearing assembly 2; and the winding and unwinding rope assembly 51 is a manual hoist. Specifically, the guide wheel 52 is fixed by a fixing seat installed on the side of the sliding rail 1 away from the lifting assembly 4; and the traction rope 511 is arranged along the length direction of the sliding rail 1 and wound around the outer side of the guide wheel 52 and connected with a traction fixing point 53 provided on the sliding load-bearing assembly 2. The manual hoist is installed at the bottom of the side of the sliding rail 1 close to the lifting assembly 4, and the hook of the manual hoist is connected with one end of the traction rope 511; in use, the chain connected with the hook is tightened to make the chain and the traction rope 511 straight (tight), and in the straight state, the chain and the traction rope 511 are arranged along the length direction of the sliding rail 1; in the process of tightening the chain, 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 the position right above the hoisting point is reached, the manual hoist stops working; and then the lifting assembly 4 controls the hoisting and lifting assembly 3 to move close to the bridge damper 10 and the two are connected.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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 is moved to the installation point along the length direction of the sliding track 1 under the control of the lifting assembly 4; since the bridge damper 10 is connected with the bottom of the box girder by means of bolting or the like, the position of the bridge damper 10 needs to be fine-tuned during the connection; for this purpose, after the bridge damper 10 is moved to the installation point, the lifting assembly 4 needs to lower a small section of the hoisting rope 33, and after that, when the monitoring assembly one 6 senses that the hoisting rope from the rope locker 22 to the lifting assembly 4 is loosened, the rope locker 22 is unlocked and no longer locks the hoisting rope 33, so that the installation of the bridge damper 10 can be performed.

[0025] The sliding table 21 is provided with a monitoring assembly two 7 for monitoring the position relationship between the hoisting member 32 and the sliding table 21; Specifically, when the lifting assembly 4 lifts the bridge damper 10, the monitoring assembly two 7 will monitor whether the hoisting member 32 moves to the highest point, and when it moves to the highest point, the rope locker 22 will lock the rope; Further, the monitoring assembly one 6 can adopt a tension tester, and the monitoring assembly two 7 can adopt a laser position sensor.

[0026] In some possible embodiments, the lifting assembly 4 is a lifting machine, and the winding and unwinding rope assembly 51 is a manual hoist; the lifting machine, the manual hoist and the rope locker 22 are prior art, and the improvement point of the present application is not in this regard, and therefore will not be described in detail.

[0027] On the other hand: The present application provides a hoisting method of the split type quickly detachable bridge damper 10 hoisting tool according to the above, which specifically comprises the following steps: Step S1: Assemble the bridge damper 10 hoisting tool, and install the bridge damper 10 hoisting tool at the bottom of the box girder; Step S2: The horizontal driving assembly 5 tightens the traction rope 511 to control the sliding load-bearing assembly 2 to move along the length direction of the sliding track 1 and to the side 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 for connecting the horizontal driving assembly 5 and the sliding load-bearing assembly 2 is taut; Step S3: The lifting assembly 4 controls the hoisting 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 lifted to the highest point, stop lifting, and lock the rope connected with the lifting assembly 4 and the hoisting lifting assembly 3 through the hoisting rope locker 22; Step S5: manually control the hoist rope 511 to relax, and control the whole structure formed by the bridge damper 10, the lifting hoisting assembly 3, the sliding load-bearing assembly 2 and the rope locker 22 to move to the side close to the lifting assembly 4 until the bridge damper 10 is moved to the installation point; Step S6: after the bridge damper 10 is moved to the installation point, the bridge damper 10 is connected to the box girder by bolting, and the hole position is fine-tuned; for this, the lifting assembly 4 lowers a small section of the hoisting rope 33, and when the monitoring assembly 6 senses that the steel wire rope from the rope locker 22 to the hoist is loose, the rope locker 22 is unlocked, and the bridge damper 10 is installed; specifically, the length of the hoisting rope 33 is lowered according to the on-site requirements.

[0028] The lifting assembly 4 is used as the main lifting power in the present application, which can be applied to various height hoisting operations without considering the problems of rope storage, rope arrangement, steel wire rope guiding and mutual interference with other operation surfaces, and the sliding load-bearing assembly 2 and the lifting hoisting assembly 3 can change the single ratio steel wire rope of the lifting assembly into a multiple ratio steel wire rope according to the weight of the hoisting component to meet the hoisting needs. The present application can quickly complete assembly and disassembly in the limited space between the beam bottom and the pier, and the arrangement is simple and easy to operate, only two fixed lifting lug plates and lifting lugs need to be welded on site to realize connection, the direction of the lifting lug is determined according to the translation direction of the bridge damper 10, the tool arrangement and damper hoisting operation can be completed, and the hoisting direction can be arbitrarily adjusted to completely avoid obstacles below the hoisting. The horizontal driving assembly 5 can vertically lift the bridge damper 10 and move it in the installation direction of the bridge damper 10, which can meet the hoisting construction operation of the obstacle existing below the installation position in the limited operation space.

[0029] The present application is light and can be quickly assembled and disassembled, and can be repeatedly used for different hoisting conditions.

[0030] In the present application, the hoist is installed and fixed at the end of the sliding rail, avoiding the traditional way of hoisting the component on the steel wire rope by the hoist, and the bridge damper 10 is installed in the limited space, which leaves more operable space for the hoisting and installation of the bridge damper 10, and makes the installation of the bridge damper 10 more simple.

[0031] The present application is not limited to the foregoing specific embodiments. The present application extends to any new feature or any new combination disclosed in the specification, and any new method or process steps or any new combination disclosed.
