Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure vibration reduction, and in particular relates to a steel structure vibration reduction device and method. Background Art

[0002] Currently, steel structures have become commonplace in the construction industry due to user or functional requirements. Steel components are assembled using welding processes to meet the strength and design requirements. When a steel component is assembled onto another steel structure, it is provided with at least one welding point, where it is welded to the other steel structure. The steel component also has at least one stress point, where it is connected to the other structure, to maintain stability and facilitate welding at the weld point. For example, the stress point of a steel component can be placed on another structure to maintain the designed state of the steel component and facilitate welding at the weld point. Alternatively, the stress point of a steel component can be connected to a sling as a suspension point for a lifting device, maintaining a temporary cantilevered state and facilitating welding at the weld point. However, during construction, steel structures are often subjected to external forces, causing vibrations. The source of the vibrations may be located in other environmental structures outside the steel component, or in the steel component itself. For example, when suspended steel components collide with steel structures (environmental structures), or when construction workers adjust or assemble steel components, collisions occur, which will cause the steel components or steel structures to vibrate. We call the origin of the vibration the epicenter. The vibration generated by the epicenter is transmitted directly through the steel component itself or indirectly through the force-bearing points of the steel component to the welding points of the steel components being assembled, resulting in poor stability of the welding points, reduced docking accuracy, and affected welding quality.

DETAILED DESCRIPTION

[0051] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] The grid structure used in current steel structures is a spatial structure composed of multiple pipes connected by nodes in a specific grid pattern. It has the advantages of spatial force bearing, light weight, high rigidity, and good earthquake resistance. It can be used as the roof of buildings such as gymnasiums, theaters, exhibition halls, waiting rooms, stadium stand canopies, aircraft hangars, and two-way large-column grid structure workshops. Each node of the grid structure in a steel structure building is a steel ball structure. Multiple rod-shaped, tubular, or strip-shaped steel structures are welded to the steel ball structures at each node to form a grid-like spatial structure. The end where the steel structure is welded to the steel ball structure (or the first environment structure) is considered a welding point of the steel structure, and the connection point where the steel structure connects to the second environment structure that can transmit vibration is considered a stress point. The second environment structure can be another steel structure or a sling for lifting equipment. In order to achieve welding, the steel structure must have at least one stress point to maintain a certain relative stability. In order to improve the welding construction efficiency of the grid, multiple steel structures are usually welded at the same time. During this process, the steel structures will inevitably be affected by the vibration of other structures. The location where the vibration occurs is called the earthquake source. The earthquake source may be on a steel structure that needs to be welded, or on other steel structures that have already been welded. The vibration generated by the earthquake source is transmitted to the welding points of the steel structure being assembled, resulting in poor welding point stability, affecting the docking accuracy and welding quality. In order to overcome the impact of vibration on steel structure welding, the present invention proposes a steel structure shock absorption device.

[0053] like Figure 1-4The steel structure shock-absorbing device shown includes a device body 1, a power source (not shown) and at least two sets of clamping parts 2. The device body 1 has a hollow structure; the power source is installed at the hollow structure of the device body 1. The power source is connected to the device body 1, or the power source abuts against one side of the device body 1, and forms a split structure with the device body 1. When the power source is separated from the device body 1, the device body 1 can be manually pushed to move on the steel structure (the steel structure is a steel pipe in this embodiment), thereby reducing the moving weight of the steel structure shock-absorbing device and facilitating manual operation. The power source is configured to drive the device body 1 to move on the steel structure according to the shock absorption requirements. Under the action of the power source, the steel structure shock-absorbing device is sufficient to move on the current steel structure. When it is necessary to approach the force point (or shock source) or to approach the welding point, the power source is started to drive the steel structure shock-absorbing device to move.

[0054] in, Figure 1 The part indicated by the middle arrow is a partial top view of the inner side of the clamping part 2.

[0055] At least two groups of clamping parts 2 are symmetrically hinged to the device body 1; the clamping part 2 has a first energy dissipation structure 3 and a resistance part 4 connected to the first energy dissipation structure 3; the clamping part 2 is configured to position the device body 1 at a specified position on the steel structure based on the shock absorption requirement, and contact the steel structure through the resistance part 4 to transfer the vibration to the first energy dissipation structure 3 to eliminate or transfer the vibration on the steel structure.

[0056] In this embodiment, the clamping part 2 is a robotic arm with a predetermined arc shape, and the connecting end of the robotic arm is transmission-connected to an articulated cylinder, which is fixed to the device body 1. The movable end of the robotic arm is used to form a clamping space in combination with the device body 1, and the clamping space is used to hold the steel pipe to achieve the positioning of the device body 1 on the steel pipe. In other words, positioning is achieved by the large-area contact between the inner surface of the robotic arm and the steel pipe. At the same time, in order to transfer vibration or eliminate the sense of vibration, a first energy dissipation structure 3 is provided on the inner surface of the clamping part 2 (i.e., the inner surface of the robotic arm in this embodiment), and a resistance part 4 is provided on the first energy dissipation structure 3. The resistance part 4 further increases the contact surface area with the steel pipe to better absorb and transfer vibration. In other words, through the contact between the resistance part 4 and the steel structure, the vibration is transferred to the first energy dissipation structure 3 to eliminate or transfer the vibration on the steel structure. In this embodiment, the resistance part 4 is a layer of viscoelastic material.

[0057] Based on the above description, the steel structure shock absorbing device is positioned on the steel pipe and vibration absorption and transfer is achieved by the retractable or expandable clamping portion 2. Therefore, when the steel structure shock absorbing device is positioned, the clamping portion 2 is driven by driving the articulated cylinder.

[0058] When the steel structure shock-absorbing device needs to move a short distance on the same steel pipe according to actual conditions, it is achieved by using a power source.

[0059] The power source includes a driving motor, a rotating shaft 8 and a driving wheel 7 .

[0060] The driving motor is installed on the device body 1, and the driving motor has an output shaft. The rotating shaft 8 is connected to the output shaft of the driving motor. The rotating shaft 8 is rotatably installed in the hollow structure of the device body 1 along a predetermined direction, and at least one driving wheel 7 is installed on the rotating shaft 8. The driving wheel 7 is rotatably installed on the device body 1, and the driving wheel 7 is connected to the output shaft of the driving motor; the outer side of the wheel surface of the driving wheel 7 is in contact with the steel structure, and the inner side of the wheel surface of the driving wheel 7 is connected to the second energy dissipation structure 602. In this embodiment, since the steel structure shock absorbing device acts on the steel pipe, two driving wheels 7 are preferably used, and the movement of the driving wheel 7 on the steel pipe is achieved by the wheel surface of the driving wheel 7 being in contact with the steel pipe.

[0061] In some embodiments, the power source has two sets of rotating shafts 8, and the two sets of rotating shafts 8 are arranged in a manner similar to the embodiment of the present invention. Figure 1 The height direction of the device body 1 shown is kept spaced and parallel. A driving wheel 7 is provided at each end of each set of rotating shafts 8, and each set of rotating shafts 8 is connected to a driving motor.

[0062] Because part of the power source is in contact with the steel structure, the steel structure vibration reduction device further includes a second energy dissipation structure 602 to improve the vibration reduction effect. The second energy dissipation structure 602 is provided on the power source. In this embodiment, the second energy dissipation structure 602 is provided on the inner side of the driving wheel 7 of the power source.

[0063] In order to improve the stability and firmness of the steel structure shock absorbing device in moving on the steel pipe, the steel structure shock absorbing device of this embodiment also includes an auxiliary mechanism, which includes: a bidirectional cylinder, a support member 5, and a support wheel 6.

[0064] The bidirectional cylinder is installed on the device body 1; the bidirectional cylinder has two output ends. Each output end is connected to a support member 5. Figure 1 As shown, each support member 5 is arranged horizontally, and each support member 5 is correspondingly arranged below a clamping portion 2. Of course, in some embodiments, the support member 5 can also be arranged above the clamping portion 2. The support wheel 6 is hinged to the support member 5, and the support wheel 6 is also in contact with the steel structure. The inner side of the wheel surface of the support wheel 6 is connected to the second energy dissipation structure 602. The support wheel 6 adopts a hinged installation method, the purpose of which is to be suitable for steel pipes with different outer diameters and to ensure that the wheel surface of the support wheel 6 can fit the steel pipe with the largest area. The stability and firmness of the steel structure shock absorber on the steel pipe are increased.

[0065] Based on the above structure, the steel structure shock-absorbing device is installed on the steel pipe as follows: the two sets of clamping parts 2 are driven away from each other by the articulated cylinder to open the clamping space formed by the device body 1 and the two sets of clamping parts 2, forming an open structure that the steel pipe can enter laterally. Similarly, the two-way cylinder drives the two support members 5 away from each other to separate the two support wheels 6 to expand the opening of the open structure formed by the support members 5, the support wheels 6 and the device body 1. The device body 1 is put on the steel pipe through the opened open structure. Then the articulated cylinder and the two-way cylinder are controlled to move relative to each other, so that the clamping space is closed, and the two sets of clamping parts 2 and the two support wheels 6 are clamped on the steel pipe.

[0066] When the steel structure shock absorber needs to move on the same steel pipe, the articulated cylinder first controls the clamping part 2 to move in opposite directions, so that the clamping part 2 no longer clamps the steel pipe. Then, the drive motor is started, and the driving wheel 7 rotates on the steel pipe, driving the steel structure shock absorber to move on the steel pipe. During movement, the support wheel 6 rotates on the steel pipe as a driven wheel. After it is transferred to the specified position, the articulated cylinder controls the clamping part 2 to move relative to the steel pipe, so that the interference part 4 is in contact with the steel pipe, and the clamping part 2 clamps the steel pipe.

[0067] In this embodiment, Figure 3 The support wheel 6 shown includes a wheel body 601 and a plurality of rolling surfaces 603 .

[0068] The wheel axle of the wheel body 601 is hinged to the support member 5 , and the wheel surface of the wheel body 601 is provided with a plurality of mounting grooves along the circumferential direction. A second energy dissipation structure 602 is installed on the inner side of each mounting groove corresponding to the wheel surface.

[0069] Several rolling surfaces 603 are mounted on the outer sides of the corresponding wheel surfaces in the mounting slots, one for each. These rolling surfaces 603 are connected to the second energy dissipation structure 602 inside the mounting slots. The curvature of the rolling surfaces 603 matches that of the wheel body 601. When the support wheel 6 contacts the steel pipe surface, the vibrations are absorbed by the rolling surfaces 603 on the support wheel 6 and transferred to the connected second energy dissipation structure 602.

[0070] In this embodiment, the structure of the driving wheel 7 can also be seen in Figure 3 As shown. The structure of the driving wheel 7 is similar to that of the support wheel 6, except that the wheel body 601 of the support wheel 6 is hingedly connected to the support member 5, while the wheel body 601 of the driving wheel 7 is drivingly connected to the output shaft of the drive motor. The specific structure of the driving wheel 7 is not further described in this embodiment. When the driving wheel 7 contacts the steel pipe surface, the wheel surface or rolling surface 603 of the driving wheel 7 absorbs the vibration and transfers it to the second energy dissipation structure 602 connected thereto.

[0071] In this embodiment, the structures of the first energy dissipation structure 3 and the second energy dissipation structure 602 are substantially the same, except that they are installed in different locations. Figure 2、 Figure 4 As shown, the second energy dissipation structure 602 includes an energy dissipation cavity 301 , an elastic member 303 , an arc-shaped plate 304 and a column 305 .

[0072] A spring 302 is axially placed inside the energy dissipation cavity 301 , and one end of the spring 302 is fixedly connected to the bottom of the energy dissipation cavity 301 .

[0073] The curved plate 304 is elastically connected to the support wheel 6 of the auxiliary mechanism or the driving wheel 7 of the power source via the elastic member 303. When the second energy dissipation structure 602 is mounted on the auxiliary mechanism, the curved plate 304 is elastically connected to the support wheel 6 of the auxiliary mechanism via the elastic member 303. When the second energy dissipation structure 602 is mounted on the power source, the curved plate 304 is elastically connected to the driving wheel 7 of the power source via the elastic member 303.

[0074] One end of the column 305 is connected to the arc-shaped plate 304, and the other end extends into the energy dissipation cavity 301 and penetrates the spring 302; the outer wall of the column 305 is axially provided with a surrounding groove 306, and the other end of the spring 302 is movably arranged in the groove 306.

[0075] The elastic member 303 of the second energy dissipation structure 602 includes a connecting plate 303a, a fixing plate 303c and at least two groups of compression springs 303b.

[0076] The connecting plate 303a is fixedly connected to the arc-shaped plate 304;

[0077] The fixing plate 303c is fixedly connected to the support wheel 6 of the auxiliary mechanism or the driving wheel 7 of the power source. When the second energy dissipation structure 602 is installed on the auxiliary mechanism, the fixing plate 303c of the elastic member 303 is fixedly connected to the inner side of the support wheel 6 of the auxiliary mechanism. When the second energy dissipation structure 602 is installed on the power source, the fixing plate 303c of the elastic member 303 is fixedly connected to the inner side of the driving wheel 7 of the power source. The fixing plate 303c is perforated along its thickness to provide the required clearance space for the column 305.

[0078] At least two groups of compression springs 303b are installed between the connecting plate 303a and the fixing plate 303c.

[0079] Since the structures of the first energy dissipation structure 3 and the second energy dissipation structure 602 in this embodiment are roughly the same, the difference is that the installation locations are different. Figure 2 、 Figure 4 As shown, the first energy dissipation structure 3 includes an energy dissipation cavity 301 , an elastic member 303 , an arc-shaped plate 304 and a column 305 .

[0080] The energy dissipation cavity 301 has a spring 302 axially disposed therein, with one end of the spring 302 fixedly connected to the bottom of the energy dissipation cavity 301 ;

[0081] The arc-shaped plate 304 is elastically connected to the clamping portion 2 via the elastic member 303 ; the arc-shaped plate 304 is also fixedly connected to the abutting portion 4 .

[0082] One end of the column 305 is connected to the arc-shaped plate 304, and the other end extends into the energy dissipation cavity 301 and penetrates the spring 302; the outer wall of the column 305 is axially provided with a surrounding groove 306, and the other end of the spring 302 is movably arranged in the groove 306.

[0083] Combined with attachment Figure 1 、 2 The elastic member 303 of the first energy dissipation structure 3 includes: a connecting plate 303a, a fixing plate 303c and at least two groups of compression springs 303b.

[0084] Connecting plate 303a is fixedly connected to curved plate 304. Fixed plate 303c is fixedly connected to the outer side of clamping portion 2. Fixed plate 303c is perforated along its thickness to provide the necessary clearance for column 305. At least two sets of compression springs 303b are installed between connecting plate 303a and fixed plate 303c.

[0085] Taking the first energy dissipation structure 3 as an example, its operating principle is as follows: when the contact portion 4 contacts the steel pipe, due to its viscoelastic material, the contact portion 4 and the steel pipe resonate, causing the column 305 to oscillate within the spring 302. Since the other end of the spring 302 contacts the groove 306 on the column 305, it encounters a certain amount of resistance. As a result, the frequency of the column 305's oscillation gradually decreases or even disappears, meaning that the vibration is gradually offset by the resistance. At the same time, the elastic member 303 also vibrates, and the vibration is transferred to the elastic member 303 and dispersed.

[0086] In order to accurately obtain the required position and quantity of the steel structure shock-absorbing device, the steel structure shock-absorbing device of this embodiment also includes at least one vibration sensor, which is arranged on the steel pipe; the vibration sensor is configured to collect vibration information on the steel pipe; the vibration information includes at least: vibration amplitude and vibration frequency.

[0087] When vibration occurs, the vibration amplitude and frequency are collected by the vibration sensor, and the number and placement of the steel structure shock-absorbing devices are determined based on the vibration amplitude and frequency.

[0088] The steel structure shock absorption device also includes a control module and a communication module that are communicatively connected. The communication module is also communicatively connected to the vibration sensor and the power source. The control module sends a control instruction to the power source based on the vibration information received from the vibration sensor. The power source drives the device body 1 to move on the steel structure based on the control instruction.

[0089] The contact portion 4 on the clamping portion 2, the supporting wheel 6 and the driving wheel 7 are in contact with the steel pipe respectively to achieve vibration transfer, and vibration transfer and vibration offset are achieved respectively through the elastic member 303 and the first energy dissipation structure 3 / the second energy dissipation structure 602, thereby preventing the vibration from moving in the direction of the welding point and ensuring the required stability of the welding point.

[0090] Based on the same inventive concept, the present invention further proposes a steel structure welding method, which uses the steel structure vibration reduction device of any of the above embodiments, comprising the following steps:

[0091] Determine the welding points where the steel structure needs to be welded to the first environment structure, and determine the stress points where the steel structure is connected to the second environment structure and can transmit vibration.

[0092] The steel structure is clamped by using the clamping portion 2 of the steel structure shock-absorbing device, so that the device body 1 of the steel structure shock-absorbing device is installed between the welding point and the stress point of the steel structure.

[0093] In some embodiments, the location of the seismic sources is further determined. When the number of seismic sources is relatively small, the locations of the seismic sources can be determined first, and based on the locations of the seismic sources, the steel structure vibration damping devices can be installed between the weld points and the seismic sources. In other words, when the number of seismic sources is less than the number of stress points, the steel structure vibration damping devices are installed between the weld points and the seismic sources to improve efficiency; when the number of seismic sources is greater than the number of stress points, the steel structure vibration damping devices are installed between the weld points and the stress points.

[0094] The abutment portion connected to the first energy dissipation structure 3 is in contact with the steel structure to transfer the vibration into the first energy dissipation structure 3 to eliminate or transfer the vibration on the steel structure; based on the vibration reduction requirements, the power source of the steel structure vibration reduction device is used to drive the device body 1 to move on the steel structure;

[0095] Weld the welding points of the steel structure to the first environment structure.

[0096] In some embodiments, a second energy dissipation structure 602 is further included to eliminate or divert vibrations on the steel structure. The second energy dissipation structure 602 is provided on the power source. The steel structure vibration reduction device also includes an auxiliary mechanism. The auxiliary mechanism is provided with the second energy dissipation structure 602. For detailed structure, see the description of the steel structure vibration reduction device above.

[0097] In some embodiments, the steel structure vibration damping device further includes at least one vibration sensor disposed on the steel structure; the vibration sensor is configured to collect vibration information from the steel structure; the vibration information includes at least vibration amplitude and vibration frequency. Thus, the above method further includes the steps of: disposing the vibration sensor of the steel structure vibration damping device between a weld point and a stress point on the steel structure, with the vibration sensor maintaining a predetermined distance from the weld point; utilizing the vibration sensor to collect vibration information from the steel structure; and, based on the vibration information, driving the power source device body 1 toward or away from the stress point.

[0098] If the vibration amplitude reported by the vibration information is larger, the number of steel structure shock absorbers will be increased, or the power source will be activated to move the steel structure shock absorbers closer to the earthquake source or the stress point. If the vibration amplitude reported by the vibration information is smaller or even disappears, the number of steel structure shock absorbers will be reduced, or the power source will be activated to move the steel structure shock absorbers away from the earthquake source or the stress point.
