Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 5, an embodiment of the invention provides a multifunctional smart support, which includes at least two height-adjusting blocks 1, a height-adjusting base plate 2, a locking adjusting member 3 and a sensor 4, which are arranged at intervals.
Wherein, the heightening base plate 2 can be slidably pressed between the two heightening blocks 1. The locking adjusting part 3 can adjust the distance between the two heightening blocks 1 to adjust the height of the heightening base plate 2 and lock the two heightening blocks 1. The sensor 4 is used to measure the force exerted by the two height-adjusting blocks 1 on the sensor 4 when the locking adjusting member 3 is locked.
As a preferred embodiment, in order to adjust the distance between the two heightening blocks 1 by locking the adjusting member 3, the multifunctional intelligent support further comprises a lower seat plate 5 arranged at the bottom of the two heightening blocks 1, the lower seat plate 5 is usually connected with the bridge tower (bearing platform) through an anchor rod, and a plurality of friction assemblies 51 are arranged on the contact surfaces of the lower seat plate 5 and the two heightening blocks 1. The friction assembly 51 may be in a rolling and sliding manner, for example, the friction assembly 51 may be a roller, a ball or a sliding friction pair, and the sliding friction pair requires a friction coefficient as small as possible to make the measured vertical force as accurate as possible, for example, the friction assembly may be configured as a teflon plate and a stainless steel plate under a silicone grease lubricant, or a modified teflon plate and a stainless steel plate under a silicone grease lubricant, and so on.
In addition, in some embodiments, the multifunctional intelligent support further comprises a damping mechanism 6 connected with an heightening block 1, wherein the damping mechanism 6 comprises a damper 61, and the damper 61 is provided with a first connecting device 62 hinged with the heightening block 1 and a second connecting device 63 used for being hinged with the bearing platform. After the damping mechanism 6 is arranged, the transverse vibration force transmitted to the support by the main beam can be consumed, a good vibration damping function is achieved, in addition, the damping mechanism 6 is usually fixed on a bearing platform through a cushion, and due to the fact that one end of the damper 61 is hinged to the heightening block 1, the support can be limited after the damping mechanism 6 is fixed. In the limit condition of the multifunctional intelligent support in this embodiment, the support needs to bear the horizontal transverse force transmitted by the main beam, and under the action of the damper 61, it is considered that there is no relative movement between the height-adjusting block 1 and the lower seat plate 5, and the relative movement only occurs between the height-adjusting block 1 and the height-adjusting base plate 2 (the height-adjusting base plate 2 moves obliquely upward relative to the height-adjusting block 1).
It is worth to be noted that the heightening base plate 2 can be directly connected with a conventional common support, the conventional common support is connected with the main beam through an anchor rod, the conventional common support is a common support which is commonly used at present and includes but not limited to a spherical support, a friction pendulum support, a rubber support and the like, and the multifunctional intelligent support can be connected with the conventional common support to realize the function of the support. In addition, the components of the conventional common support can be directly designed on the heightened base plate 2 to realize the functions of the support. For example, a support member 21 is disposed on top of the height-adjustable base plate 2, and the support in the support member 21 is a ball support, a friction pendulum support, or a rubber support.
In some embodiments, the height-adjusting blocks 1 comprise a wedge-shaped surface, and the height-adjusting base plate 2 is slidably pressed on the wedge-shaped surface of the two height-adjusting blocks 1. That is, heightening block 1 is a wedge-shaped sliding block, and is in contact with heightening base plate 2 through a sliding friction pair, that is, heightening block 1 is in sliding friction contact with heightening base plate 2. In addition, because the lower seat plate 5 is provided with a roller or a ball, the height-adjusting block 1 is placed on the roller or the ball, namely, the height-adjusting block 1 and the lower seat plate 5 are in rolling friction contact. It can be understood that rolling friction contact can be realized between the height-adjusting block 1 and the height-adjusting base plate 2 by using rolling shafts or rolling balls, and sliding friction contact can be realized between the height-adjusting block 1 and the lower base plate 5 by using a sliding friction pair.
In some embodiments, the height-adjusting blocks 1 are symmetrically arranged about the height-adjusting base plate 2, and may be 2 or 4. The bottom of the heightening block 1 is provided with a through hole, a locking adjusting piece 3 can penetrate through the through hole, the locking adjusting piece 3 can be a screw rod, at least 2 through holes are formed in the bottom of the heightening block 1, the number of corresponding screw rods is at least 2, the specific number can be determined according to the vertical bearing capacity of the support, and the embodiment is not limited herein. It should be noted that the screw is locked after being synchronously tensioned and stressed when the screw is installed, and the final state is that the force on the heightening base plate 2 is uniformly shared on the heightening block 1, and the force of the heightening block 1 is shared on the locked screw.
The sensor 4 can be arranged between two height-adjusting blocks 1, see fig. 1, or the sensor 4 can be arranged on the end of a screw, see fig. 5. It is worth mentioning that when the sensor 4 is arranged between the two heightening blocks 1, for example, the sensor 4 is arranged between the heightening blocks 1 which are symmetrically arranged, the pressure is always required between the sensor 4 and the heightening blocks 1 under the action of the shaft force of the screw, and the tensile force is not allowed to occur. In addition, in order to ensure the accuracy of the measurement, the diameter of the hole in the height-adjusting block 1 is generally required to be larger than the diameter of the screw, so as to avoid the friction force between the height-adjusting block 1 and the screw from affecting the measurement of the sensor 4.
Under the action of the shaft force of the screw, the pressure between the sensor 4 and the height-adjusting block is required to be always pressure, and the tension is not allowed to occur. The sensor 4 can monitor whether the multifunctional intelligent support is empty or not, and when the force on the sensor 4 is obviously smaller than a normal value and even approaches zero, the support is indicated to be empty.
The sensor 4 can also be used for monitoring whether the vehicle is overloaded, and when the force on the sensor 4 is greater than an overload threshold value (can be confirmed according to the use load of the bridge), the worker can be reminded that the vehicle is overloaded, so that safety accidents are prevented.
When the support is empty, maintenance personnel can make the distance between two height-adjusting blocks 1 become little through the mode of screwing up bolt on the screw rod, because height-adjusting block 1 is the wedge, consequently when two height-adjusting blocks 1 distance become little, height-adjusting bed plate 2 placed on it risees. The force on the sensor 4 is gradually increased along with the distance between the height-adjusting blocks 1 is reduced, and when the force on the sensor 4 reaches a set value, the support is lifted to a preset position, and the emptied support starts to participate in the force transmission work between the lower structures on the bridge again.
In summary, the multifunctional intelligent support comprises a sensor 4 arranged between two height-adjusting blocks 1, and is used for measuring the force exerted on the sensor 4 by the two height-adjusting blocks 1 when the locking adjusting member 3 is locked. When the force on the sensor 4 is significantly smaller than the normal value, even close to zero, it indicates that the support has been emptied. When the support is emptied, the distance between the two heightening blocks 1 can be reduced by screwing the bolt on the screw, and the heightening base plate 2 placed on the heightening base plate is lifted. Along with the distance between the heightening blocks 1 becomes smaller, the force on the sensor 4 becomes larger gradually, when the force on the sensor 4 reaches a set value, the support is lifted to a preset position at the moment, the emptied support starts to participate in the force transmission work between the lower structures on the bridge again, in addition, the multifunctional intelligent support also comprises a damping mechanism 6, the damping mechanism can limit the support, and can consume the vibration force transmitted to the support by the main beam, so that a good vibration damping function is realized. Therefore, the multifunctional intelligent support can monitor the force transmission condition between the upper and lower structures of the bridge, can take effective height adjustment measures after detecting that the bridge support is empty, has certain vibration damping and vibration suppressing functions, and can well meet the current requirements.
Meanwhile, referring to fig. 6, an embodiment of the present invention further provides a method for using the multifunctional smart support, where the method includes:
s1, judging whether the multifunctional intelligent support is empty or not according to the reading on the sensor 4.
S2, when the multifunctional intelligent support is emptied, the locking adjusting piece 3 is adjusted to enable the distance between the two heightening blocks 1 to be reduced, so that the heightening base plate 2 is lifted.
In some embodiments, the locking adjuster 3 is a screw rod inserted between the two height-adjusting blocks 1.
And S3, continuously observing the reading of the sensor 4 until the reading reaches a set value, and locking the two height adjusting blocks 1 by using the locking adjusting piece 3.
It can be understood that when the support is empty, the maintenance personnel can make the distance between the two heightening blocks 1 smaller by screwing the bolt on the screw, because the heightening blocks 1 are wedge-shaped bodies, so that the heightening base plate 2 placed thereon is raised when the distance between the two heightening blocks 1 is smaller. The force on the sensor 4 is gradually increased along with the distance between the height-adjusting blocks 1 is reduced, and when the force on the sensor 4 reaches a set value, the support is lifted to a preset position, and the emptied support starts to participate in the force transmission work between the lower structures on the bridge again.
In some embodiments, the multifunctional intelligent support further comprises a damping mechanism 6 connected with an heightening block 1, wherein the damping mechanism 6 comprises a damper 61, and the damper 61 is provided with a first connecting device 62 hinged with the heightening block 1 and a second connecting device 63 for being hinged with the bearing platform. In a specific using process, after the damping mechanism 6 is arranged, the displacement of the support can be limited, the vibration force transmitted to the support by the main beam is consumed, and a good vibration damping function is achieved.
The screw rod can be deadlocked in normal use to guarantee that the pressure is always between heightening block 1 and sensor 4, and damper 61 is connected with heightening block 1 through first connecting device 62. Under the normal use condition, the part more than heightening piece 1 can follow attenuator 61 and move on the roller bearing of bedplate 5 down, and attenuator 61 connects the support, consumes the vibrational force that the girder transmitted for the support, plays good damping function. When a large earthquake occurs, the heightening base plate 2 can move along the friction pair, on one hand, the earthquake energy is consumed through the friction of the friction material, on the other hand, the earthquake energy is consumed through the gravity acting negative work, and the base plate has a certain earthquake isolation function.
The embodiment of the invention is characterized in that the vertical bearing capacity of the support is measured through the reading of the sensor 4, and the principle of the sensor 4 is explained through specific stress analysis by taking the sensor 4 arranged on a screw as an example:
in some preferred embodiments, in order to avoid that the slope θ of the height-adjusting block 1 is too small, which may cause the height-adjusting base plate 2 to slide relative to the height-adjusting block 1 in a direction close to horizontal, it is necessary to first determine the minimum slope θ of the height-adjusting block, see fig. 7 for a force analysis diagram of the height-adjusting base plate 2 and the height-adjusting block 1, when the height-adjusting base plate 2 is in contact with only one height-adjusting block 1, and when the minimum slope θ is determined, wherein:

That is, when the heightening base plate 2 is lowered, the relationship between the vertical bearing capacity G of the support and the force F of the sensor 4 is:
in summary, the relationship between the vertical bearing capacity G of the support and the force F of the sensor 4 is:
the relationship between the vertical bearing capacity G of the support and the force F of the sensor 4 is obtained, so that the situation of the vertical bearing capacity of the support can be intuitively known by observing the reading of the sensor 4, and the convenience in actual use is improved.
In addition, when calibration is needed, the sensor 4 is detached, and the ultrasonic axial force detection tool is matched for synchronizationJacking technology, when the synchronous jacking equipment tensions the screw rod to make the heightening base plate move upwards (at the moment, two heightening blocks move relatively), the force detected by the ultrasonic axial force is FIs raisedWhen the synchronous jacking equipment loosens the screw rod to enable the heightening base plate to move downwards (at the moment, the two heightening blocks move back to back), the force detected by the axial force of the ultrasonic wave is FReduceThe directions of the friction forces in the two states are just opposite, and the calibration can be carried out according to the different directions of the friction forces, and the specific calibration method comprises the following steps:
