DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0053] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] Structural vibration test technology is a mature test technology for obtaining the inherent vibration characteristics of structures. There are two main methods, the hammer method and the shaker method. Compared with the unstable excitation force of the hammer method, the excitation force of the shaker method is more stable than the hammer method, and the excitation force size and frequency band are controllable, which is suitable for various types of structures with high test accuracy requirements.

[0056] For large and complex structures or for studying the nonlinear characteristics of structures, the shaker method is the preferred method when on-site conditions permit the arrangement of shakers to ensure test results.

[0057] Normally, the shaker automatic excitation test is carried out by moving the structure under test or moving the shaker.

[0058] On the one hand, according to the comprehensive arrangement of the structure type and the excitation point, the vibration exciter is installed in a certain fixed position in advance, and then the large structure is lifted by the lifting tool. Based on the installation position of the vibration exciter, the position and angle of the structure are adjusted one by one according to the position of each excitation point, so that the vibration exciter can smoothly excite each point and carry out the vibration test. This not only increases the difficulty of structural lifting and consumes a lot of lifting time, but also has poor lifting accuracy, which affects the test data of the large-scale structure vibration test.

[0059] On the other hand, the structural excitation test has many excitation points arranged in various directions, which requires the exciter support device to flexibly adjust the exciter positioning by lifting, lowering, and displacing according to the excitation requirements. However, the existing exciter support devices on the market cannot meet these requirements. Usually, only the hammer method can be used for excitation tests. The collected test data has poor consistency and cannot be used for single-frequency or swept-frequency analysis.

[0060] Therefore, the vibration exciter support device in the related art is inconvenient to use, which makes it difficult for the vibration exciter thereon to adapt to various structures with different shapes, curved surfaces and heights.

[0061] In the related art, there is a technical problem that the exciter support device is inconvenient to use. The embodiment of the present application provides an exciter support device, which can at least solve the technical problem that the exciter support device is inconvenient to use to a certain extent.

[0062] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0063] like Figure 1 As shown, the vibration exciter support device 100 includes a support frame 110 , a sliding assembly 120 , a support assembly 130 and a vibration exciter mounting member 140 .

[0064] The sliding assembly 120 is slidably connected to the support frame 110 along a first direction and can be fixed at any position.

[0065] That is to say, the sliding component 120 can slide on the support frame 110 along the first direction. When the sliding component 120 slides to a certain position, the sliding component 120 can be fixed on the support frame 110 and no longer slides. When the sliding component 120 is to slide, the sliding component 120 is not fixed to the support frame 110, and the sliding component 120 can slide along the support frame 110. In this way, when the first direction is set at an inclined angle α with the horizontal plane, the sliding component 120 can remain fixed at different heights.

[0066] The support assembly 130 is movably connected to the support frame 110 and is used to support the support frame 110 so that the first direction can be inclined at least at two different angles α with the horizontal plane.

[0067] The support assembly 130 is located below the support frame 110 and is used to support the support frame 110. When using the vibrator support device 100 of the present application, the vibrator support device 100 is placed on a support platform 300, which may be the ground, a steel structure platform, etc., which is not limited here. The support assembly 130 is supported on the support platform 300 and is in contact with the support platform 300.

[0068] The support component 130 is movably connected to the support frame 110, which means that the support component 130 can be connected to different positions of the support frame 110, that is, it can be connected to different parts of the support frame 110. When the support component 130 is connected to different positions of the support frame 110 and the support component 130 is supported on the support platform 300, the support frame 110 can be in different position states, so that the first direction can be inclined at a variety of different angles α with the horizontal plane, so that the sliding component 120 can slide along the first direction with different angles α with the horizontal plane.

[0069] The exciter mounting member 140 has a first mounting plane 140a for mounting the exciter 200. The exciter mounting member 140 is movably connected to the sliding assembly 120 so that the first mounting plane 140a can be horizontally arranged when the first direction is at different inclination angles α with the horizontal plane.

[0070] Specifically, the vibrator 200 has a bracket 210, and the bracket 210 of the vibrator 200 is fixed on the first mounting plane 140a, and the lower end surface of the bracket 210 of the vibrator 200 is in contact with the first mounting plane 140a. The vibrator mounting member 140 is movably connected to the sliding assembly 120, which means that the vibrator mounting member 140 can be connected to different positions of the sliding assembly 120, that is, it can be connected to different parts of the sliding assembly 120. Since the support assembly 130 is movably connected to the support frame 110, when the first direction is at a plurality of different inclination angles with the horizontal plane, the position state of the sliding assembly 120 is also different. If the vibrator mounting member 140 and the sliding assembly 120 maintain a fixed arrangement that cannot be changed, then when the sliding assembly 120 is in different position states, the first mounting plane 140a cannot always be in a horizontal state, which may cause the vibrator 200 to be in a linear tilted state after being installed on the first mounting plane 140a, so that the vibrator 200 cannot achieve the function of excitation. The exciter mounting member 140 is movably connected to the sliding assembly 120 so that when the first direction is at different inclination angles with the horizontal, that is, when the sliding assembly 120 is in different positions, the exciter mounting member 140 can be installed at different positions of the sliding assembly 120 to ensure that when the sliding assembly 120 is in different positions, the first mounting plane 140a can be set horizontally to ensure that the angle of the exciter 200 thereon meets the excitation requirements.

[0071] With such a design of the present application, the vibrator 200 mounted on the vibrator mounting member 140 can slide along a first direction having different inclination angles with respect to the horizontal plane, and can be fixed at any position, so that the installation height and the moving angle of the vibrator 200 can be adjusted more flexibly, thereby enabling the vibrator 200 to adapt to the vibration test requirements of various structures and equipment with different outer shapes and surfaces and different heights by changing the installation positions of the support assembly 130 and the vibrator mounting member 140 within a limited test space without changing the placement position of the structure under test.

[0072] like Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, the sliding assembly 120 includes a sliding member 121 and a locking member 122, the sliding member 121 is slidably connected to the support frame 110; the locking member 122 is installed on the sliding member 121, and under the action of the locking member 122, the sliding member 121 can switch between a first state in which it is fixed to the support frame 110 and a second state in which it can slide along the support frame 110; the exciter mounting member 140 is movably connected to the sliding member 121.

[0073] The locking member 122 can lock the sliding member 121 and the support frame 110, so that the sliding member 121 and the support frame 110 are fixed together, so that the sliding member 121 cannot slide, and thus the sliding assembly 120 is fixed at any position. The locking member 122 can also loosen the sliding member 121 and the support frame 110, so that the sliding member 121 can slide along the support frame 110. Before sliding the sliding member 121, operate the locking member 122 so that the locking member 122 loosens the sliding member 121 and the support frame 110; then slide the sliding member 121, and after the sliding member 121 slides to the set position, operate the locking member 122 so that the sliding member 121 and the support frame 110 are fixed together, so that the sliding member 121 is fixed at the set position.

[0074] like Figure 2 As shown, in some embodiments, the support frame 110 includes a frame assembly 111 and a guide assembly 112 installed on the frame assembly 111, the sliding assembly 120 is slidably connected to the guide assembly 112, the first direction is the length direction of the guide assembly 112, and the support assembly 130 is movably connected to the frame assembly 111.

[0075] The guide assembly 112 is fixedly connected to the frame assembly 111. The guide assembly 112 can be a single piece, for example, guided by a guide rod, or can be a component composed of multiple parts, for example, guided by multiple guide rods at the same time, which is not limited in this application.

[0076] The specific structures of the frame assembly 111 and the guide assembly 112 are various. One guide assembly 112 can be provided, or multiple guide assemblies 112 can be provided. The provision of multiple guide assemblies 112 helps to improve the stability of the sliding assembly 120 when sliding and locking.

[0077] like Figure 5 As shown, in some embodiments, a plurality of guide assemblies 112 are provided, the number of sliding assemblies 120 is consistent with the number of guide assemblies 112 , and the sliding assemblies 120 and the guide assemblies 112 are provided in a one-to-one correspondence.

[0078] That is to say, a sliding assembly 120 is installed on each guide assembly 112. After such a design, the vibrator support device 100 includes multiple guide assemblies 112 and multiple sliding assemblies 120, and the vibrator mounting member 140 is installed on two sliding assemblies 120 at the same time. In this way, when the height of each sliding assembly 120 is inconsistent, the vibrator mounting member 140 can be tilted so that the first mounting plane 140a thereon can be tilted; when the height of each sliding assembly 120 is consistent, the vibrator mounting member 140 can be horizontally set so that the first mounting plane 140a thereon can be horizontally set. The first mounting plane 140a has other position states besides the horizontal setting, so that the vibrator support device 100 can be applicable to more application scenarios and can be applicable to vibrators 200 with different structures. In addition, with such a design, the vibration exciter mounting member 140 is installed on multiple sliding assemblies 120 at the same time, and the connection between the vibration exciter mounting member 140 and the sliding assembly 120 is more secure, which helps to ensure the stability of the vibration exciter 200 thereon.

[0079] like Figure 2 As shown, in some embodiments, each guide assembly 112 includes two parallel and spaced guide rods 1121, and the first direction is the length direction of the guide rod 1121. Figure 8 As shown, two sliding holes 120d are provided on the sliding assembly 120 , and the cross-section of the sliding hole 120d is adapted to the cross-section of the guide sliding rod 1121 . The guide sliding rod 1121 is located in the through hole so that the sliding assembly 120 can slide along the guide sliding rod 1121 .

[0080] like Figure 8 As shown, in some embodiments, the sliding member 121 includes two sliding parts 1211, a connecting part 1212 and a fixed part 1213, the connecting part 1212 is connected to the two sliding parts 1211, two fixed parts 1213 are provided, the two fixed parts 1213 are located between the two sliding parts 1211, and are respectively fixedly connected to the two sides of the connecting part 1212, and the exciter mounting member 140 is installed on the fixed part 1213.

[0081] like Fig. 9 As shown, the sliding part 1211 includes a sliding part connecting part 12111, a first deformation part 12112 and a second deformation part 12113. The first deformation part 12112 and the second deformation part 12113 are arranged opposite to each other. A sliding hole 120d is provided on the sliding part connecting part 12111, and a gap between the first deformation part 12112 and the second deformation part 12113 is connected to the sliding hole 120d. A through hole is provided on the first deformation part 12112, and a threaded hole is provided on the second connecting part 1212. Fig.10As shown, the locking member 122 includes a handle portion 1221 and a screw portion 1222 that are fixedly connected, and the screw portion 1222 passes through the through hole and is threadedly connected to the threaded hole. In these embodiments, the guide rod 1121 is located in the sliding hole 120d. When the locking member 122 is tightened, the handle portion 1221 presses against the first deformation portion 12112, so that the first deformation portion 12112 and the second deformation portion 12113 gradually move closer, so that the size of the sliding hole 120d becomes smaller, and then the sliding member 121 clamps the sliding rod, and the sliding member 121 is fixed to the sliding rod. When the locking member 122 is loosened, the handle portion 1221 no longer presses against the first deformation portion 12112, so that the first deformation portion 12112 and the second deformation portion 12113 gradually move away from each other, so that the size of the sliding hole 120d becomes larger, and then the sliding member 121 releases the sliding rod, and the sliding member 121 can slide along the sliding rod.

[0082] The setting of the handle part 1221 can facilitate the user to rotate the screw part 1222. The structure is diverse and is not limited here. For ease of use, an anti-slip rubber sleeve can be provided thereon.

[0083] like Figure 4 As shown, in some embodiments, the frame assembly 111 includes a first frame 1111, a second frame 1112, a third frame 1113 and a fourth frame 1114, the first frame 1111 has a first end and a second end arranged opposite to each other along the second direction, the second frame 1112 has a third end and a fourth end arranged opposite to each other along the third direction, the third frame 1113 has a fifth end and a sixth end arranged opposite to each other along the fourth direction, and the fourth frame 1114 has a seventh end and an eighth end arranged opposite to each other along the first direction; the second end is fixedly connected to the third end, the fourth end is fixedly connected to the fifth end, the sixth end is connected to the seventh end, and the eighth end is connected to the first end; the second direction is angled with the third direction, the third direction is angled with the fourth direction, and the first direction is angled with the second direction, and the sliding component 120 is installed on the third frame 1113 and / or the first frame 1111; the supporting component 130 is detachably connected to the first frame 1111, the second frame 1112 or the third frame 1113, so that the first direction can be inclined at three different angles α with the horizontal plane.

[0084] The specific structures of the first frame 1111, the second frame 1112, the third frame 1113 and the fourth frame 1114 are not limited in this application. After such a design, the first frame 1111, the second frame 1112, the third frame 1113 and the fourth frame 1114 are surrounded to form a ring structure connected end to end.

[0090] It should be noted that the first mounting surface 120a, the second mounting surface 120b and the third mounting surface 120c are all planes. After such design, when the support group is connected to the first frame 1111, the second mounting surface 120b is horizontally arranged, and the second mounting plane 140b of the exciter mounting component 140 is in contact with the second mounting surface 120b, thereby making the first mounting plane 140a of the exciter mounting component 140 horizontally arranged; when the support assembly 130 is connected to the second frame 1112, the first mounting surface 120a is horizontally arranged, and the second mounting plane 140b of the exciter mounting component 140 is in contact with the second mounting surface 120b, thereby making the first mounting plane 140a of the exciter mounting component 140 horizontally arranged; when the support assembly 130 is connected to the third frame 1113, the third mounting surface 120c is horizontally arranged, and the second mounting plane 140b of the exciter mounting component 140 is in contact with the third mounting surface 120c, thereby making the first mounting plane 140a of the exciter mounting component 140 horizontally arranged.

[0095] like Fig.12 As shown, in some embodiments, the support assembly 130 includes a support member 131, a roller 132 and an adjusting member 133, the roller 132 and the adjusting member 133 are both installed on the support member 131, the adjusting member 133 is used to level the support member 131, and the support member 131 is movably connected to the support frame 110.

[0096] The roller 132 is disposed at the lower part of the support member 131, and the roller 132 is in contact with the support platform 300. Under the action of the roller 132, the vibrator support device 100 can slide on the support platform 300, which facilitates the movement of the vibrator support device 100. The adjustment member 133 is installed on the support member 131, and the adjustment member 133 can move toward the support platform 300 or move away from the ground, so that the adjustment member 133 can be in contact with the support platform 300 or not in contact with the support platform 300. When the support platform 300 is uneven, the support member 131 can be made horizontal by adjusting the adjustment member 133, thereby making the vibrator support device 100 horizontally arranged.

[0097] The structure of the roller 132 is well known to those skilled in the art and will not be elaborated here. A braking device, such as a brake pad, may be provided on the roller 132 to enable the roller 132 to be locked.

[0098] In some embodiments, the adjusting member 133 has a fixedly connected adjusting member rotating portion 1331 and an adjusting member threaded connection portion 1332. A threaded through hole is provided on the support member 131. The adjusting member threaded connection portion 1332 of the adjusting member 133 is threadedly connected in the threaded through hole, and its lower end protrudes from the threaded through hole. By rotating the adjusting member rotating portion 1331, the length of the lower end of the adjusting member threaded connection portion 1332 protruding from the threaded through hole can be adjusted, thereby leveling the support member 131. The adjusting member rotating portion 1331 can be a hand wheel, and the adjusting member threaded connection portion 1332 can be a stud, and the hand wheel is welded to the upper end of the stud.

[0099] In some embodiments, the support member 131 includes a connecting member 1311, a first arm 1312, and a second arm 1313. The first arm 1312 and the second arm 1313 are arranged opposite to each other. One end of the connecting member 1311 is connected to one end of the first arm 1312, and the other end is connected to one end of the second arm 1313. The first arm 1312 and the connecting member 1311 are arranged at an obtuse angle, and the second arm 1313 and the connecting member 1311 are also arranged at an obtuse angle. Two rollers 132 are provided, and the two rollers 132 are respectively provided on the side of the first arm 1312 and the second arm 1313 away from the connecting member 1311. Two adjusting members 133 are also provided, and the two adjusting members 133 are respectively provided on one end of the first arm 1312 and the second arm 1313 away from the connecting member 1311. In these embodiments, the connecting member 1311 is movably connected to the first frame 1111, the second frame 1112, or the third frame 1113. The exciter support device 100 is provided with two support members 131, and the two support members 131 are respectively connected to the two sides of the first frame 1111 along the second direction (such as Fig.14 ), respectively connected to the second frame 1112 along the third direction of the two sides (as shown Fig.16) or respectively connected to both sides of the third frame 1113 along the fourth direction (as shown Fig.18 As shown), to ensure the stability of the exciter supporting device 100.

[0100] During the use of the exciter 200 , the height of the exciter 200 will be adjusted to excite various locations in the height direction of the object to be detected. The exciter 200 is heavy, and if the exciter 200 is moved manually, the labor intensity is relatively high.

[0101] like Figure 1 As shown, in some embodiments, the vibration exciter support device 100 further includes a driving assembly 150, and the driving assembly 150 is used to drive the sliding assembly 120 or the vibration exciter mounting member 140 to move along the first direction.

[0102] Since the exciter mounting member 140 is mounted on the sliding assembly 120, and the exciter 200 is mounted on the exciter mounting member 140, the driving assembly 150 can drive the sliding assembly 120, the exciter mounting member 140 and the exciter 200 to move together, so as to adjust the height of the exciter 200, regardless of whether the driving assembly 150 drives the sliding assembly 120 to slide along the first direction or drives the exciter mounting member 140 to move along the first direction. By driving the sliding assembly 120, the exciter mounting member 140 and the exciter 200 to move together, it helps to reduce the intensity of manual labor and makes it easier to use the exciter support device 100.

[0103] The various structures of the driving assembly 150 are not limited in this application. The driving assembly 150 can be a single piece, for example, the driving assembly 150 is an electric push rod or a hydraulic cylinder, etc. The electric push rod or the hydraulic cylinder is arranged along the first direction, so that the telescopic rod is telescoped along the first direction, thereby driving the sliding assembly 120, the exciter mounting member 140 and the exciter 200 to move together along the first direction. The driving assembly 150 can also be an assembly formed by connecting multiple components, for example, the driving assembly 150 may include a motor, a gear, a rack and other structures, the gear is mounted on the output shaft of the motor, the motor is mounted on the sliding assembly 120, the rack is arranged along the first direction and fixed on the support frame 110, so that the motor rotates to rotate the gear, while the rack is fixed, thereby causing the sliding assembly 120, the exciter mounting member 140, the exciter 200, the motor and the gear to move together along the first direction.

[0104] It should be noted that the driving assembly 150 should be started under the condition that the sliding assembly 120 and the support frame 110 are not fixed, so as to ensure that the sliding assembly 120, the exciter mounting member 140 and the exciter 200 move together in the first direction.

[0105] like Figure 1 and Fig.13As shown, in some embodiments, the driving assembly 150 includes a driving member 152, a reel 153 and a traction member 151, the traction member 151 is connected to the reel 153 and the exciter mounting member 140, and the driving member 152 is used to drive the reel 153 to rotate so that the traction member 151 is wound around the reel 153 or released from the reel 153.

[0106] The traction member 151 may be a steel wire rope, a nylon rope, etc., the driving member 152 may be a motor, and the drum 153 is fixedly connected to the output shaft of the motor. The driving member 152 drives the drum 153 to rotate, and the traction member 151 is connected to the drum 153 and the exciter mounting member 140. When the drum 153 rotates, the traction member 151 can be wound around the drum 153 or gradually separated from the drum 153, thereby causing the sliding assembly 120, the exciter mounting member 140 and the exciter 200 to move together along the first direction.

[0107] Specifically, when the traction member 151 is gradually wound around the reel 153, the sliding assembly 120, the vibrator mounting member 140 and the vibrator 200 slide upward along the guide rod 1121, and the heights of the sliding assembly 120, the vibrator mounting member 140 and the vibrator 200 increase; when the traction member 151 is gradually released from the reel 153, under the action of gravity, the sliding assembly 120, the vibrator mounting member 140 and the vibrator 200 slide downward along the guide rod 1121, and the heights of the sliding assembly 120, the vibrator mounting member 140 and the vibrator 200 decrease. When the heights of the sliding assembly 120, the vibrator mounting member 140 and the vibrator 200 are adjusted to a suitable position, the motor stops rotating; then the sliding assembly 121 is locked with the guide rod 1121 by the locking member 122. The structure of the reel 153 is known to those skilled in the art and will not be elaborated here. The motor can be selected with a self-locking function, so that after the motor stops, the output shaft of the motor is locked and cannot rotate, so that the sliding assembly 120, the exciter mounting member 140 and the exciter 200 can be maintained at the height when the motor stops, making it convenient for the locking member 122 to lock the sliding member 121 and the guide rod 1121.

[0108] like Fig.11 As shown, in some embodiments, a plurality of traction member connection holes 140c are further provided on the exciter mounting member 140. One end of the traction member 151 is tied in the traction member connection hole 140c to be fixedly connected to the exciter mounting member 140. The plurality of traction member connection holes 140c are provided so that when the first direction is at different inclination angles α with the horizontal plane, the traction member 151 can be tied in different traction member connection holes 140c, so that the traction rope can pull the sliding assembly 120, the exciter mounting member 140 and the exciter 200.

[0109] In some embodiments, the driving assembly 150 further includes a guide wheel, which is mounted on the support frame 110 , and the traction member 151 is attached to the guide wheel, and the traction rope is guided by the guide wheel.
