Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering, and in particular to a shock-absorbing bridge support capable of self-leveling and auxiliary bearing. Background Art

[0002] Bridge bearings are subjected to long-term influences from the external environment and loads. For example, corrosion caused by chemical substances, air humidity, etc. will reduce the stability of bridge bearings. Wear caused by long-term loads, friction and other factors will lead to changes in the geometric shape of the bearings and a decrease in the friction coefficient. Loosening of bearing connections caused by material fatigue and continuous micro-vibration will lead to a decrease in the stability and bearing capacity of the bearings. Settlement caused by foundations, seismic loads and other reasons will cause the bridge to be uneven and deformed.

[0003] The existing technology generally solves the above problems by increasing the number of bearings, replacing bearings, adding supporting structures, etc., while trying to improve the level of maintenance to ensure the safety of the bridge and increase its service life. However, the above methods are generally time-consuming, labor-intensive, and the bridge cannot be normally passed during maintenance, and it is difficult to carry out in some rugged areas. In summary, it is necessary to develop a bearing that can self-level and assist in bearing, so as to save labor, reduce maintenance period, and be convenient and fast. Summary of the invention

[0004] In view of the above-mentioned technical problems, the present invention provides a shock-absorbing bridge bearing which can be self-leveled and auxiliary load-bearing.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] A shock-absorbing bridge support capable of self-leveling and auxiliary bearing includes an upper top seat plate, a spring shock-absorbing support column and a lower base plate which are sequentially arranged from top to bottom;

[0007] A rotary lifter and an infrared rangefinder with a screen display are arranged on the outer side of the spring shock-absorbing support column, and the rotary lifter and the infrared rangefinder with a screen display are located between the upper top seat plate and the lower base plate, and the upper top seat plate and the lower base plate are respectively provided with anchoring components;

[0008] The anchoring assembly on the upper top seat plate is used to connect with the bridge body, and the anchoring assembly on the lower base plate is used to connect with the cushion stone.

[0009] In a preferred embodiment: the elastic shock-absorbing support column comprises a damping column, a damping spring and an anchorable hollow sleeve which are arranged in sequence, and the damping spring is nested between the damping column and the hollow sleeve;

[0010] A buffer gasket is also arranged between the upper seat plate and the spring shock-absorbing support column.

[0011] In a preferred embodiment: the buffer gasket is connected to the damping column by a single-point anchoring, the damping column and the hollow sleeve are of an integrated design and are connected to the lower base plate by anchoring.

[0012] In a preferred embodiment: the rotary lifter comprises an anchoring pad, a steel column, a rotary column and a main body leveler arranged in sequence;

[0013] The steel column is connected to the upper top seat plate by anchoring, the main body leveler is connected to the lower base plate by anchoring, and the steel column and the rotating column are in contact with each other by controlling the leveler through the infrared rangefinder.

[0014] In a preferred embodiment, the surface of the rotating column is threaded.

[0015] In a preferred embodiment: the infrared rangefinder comprises an infrared transmitter, a screen display and an infrared receiver arranged in sequence;

[0016] The connecting gap between the infrared receiver and the screen display is connected by epoxy resin adhesive, and the infrared transmitter and the infrared receiver are connected to the steel column and the main body leveler respectively by screws.

[0017] In a preferred embodiment: a micro-judge and a rotating motor are arranged inside the main body leveler, the signal input end of the micro-judge is connected to the infrared rangefinder, and the signal output end is connected to the rotating motor; the rotating motor is used to drive the rotating column to rotate.

[0018] In a preferred embodiment: a microprocessor, a timer and a photoelectric element are disposed inside the infrared receiver, and a pulse beam transmitter is disposed inside the infrared transmitter.

[0019] In a preferred embodiment: the spring shock-absorbing support column, the rotary lifter and the infrared rangefinder with screen display are all waterproofed.

[0020] Compared with the existing conventional technology, the present invention has the following advantages:

[0021] 1. The spring shock-absorbing support column in the present invention plays a major bearing role, wherein the main force-bearing structures are the damping spring and the damping column. The damping spring has good elastic deformation and reset functions, and can better achieve shock absorption compared to a single traditional support structure. The damping column has better vertical bearing capacity. The two working together can greatly improve the vertical ultimate bearing capacity of the support, ensuring that the support has better seismic isolation and vibration reduction properties. The damping column and the damping spring are both made of structural steel, and have the characteristics of high strength, high toughness and good processability.

[0022] 2. The rotary lifter and the infrared rangefinder in the present invention can be used together to assist in bearing and automatic leveling. The infrared rangefinder has the characteristics of small size, light weight, simple operation, accurate data and low cost, and can accurately measure the displacement deviation. At the same time, the rotary lifter can adjust the displacement by lifting and lowering the deviation and can play a bearing role under specific circumstances. Compared with traditional supports, it also has great advantages in the replacement of supports. By adjusting the rotary lifter instead of the jack to provide sufficient jacking force to the top seat plate, the spring shock-absorbing support column can be replaced quickly and conveniently, thereby reducing the maintenance period.

DETAILED DESCRIPTION

[0031] 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.

[0032] like Figure 1-Figure 6 As shown: This embodiment provides a shock-absorbing bridge support that can be self-leveled and assist in bearing, including an upper top seat plate 12, a buffer gasket 9, a spring shock-absorbing support column 5 and a lower base plate 13 arranged from top to bottom; the spring shock-absorbing support column 5 and the lower base plate 13 are connected by a large anchor bolt 7, and a rotary lifter 3 is arranged on the outside of the spring shock-absorbing support column 5, and the rotary lifter 3 is located between the upper top seat plate 12 and the lower base plate 13, and is respectively connected to the upper top seat plate 12 and the lower base plate 13 by a small anchor bolt 14; the anchor assembly 1 on the upper top seat plate 12 is used to connect with the bridge body, and the anchor assembly 1 on the lower base plate 13 is used to connect with the pad stone, and a buffer gasket 9 is also arranged between the upper top seat plate 12 and the spring shock-absorbing support column 5. The spring shock-absorbing support column 5 and the buffer gasket 9 bear the main load, realizing the vertical seismic isolation and vibration reduction effect of the bridge, and the safety is high. The buffer gasket 9 separates the upper seat plate 12 from the spring shock-absorbing support column 5 to avoid loss caused by direct contact between the upper seat plate 12 and the spring shock-absorbing support column 5, while increasing the friction force of the contact surface of the spring shock-absorbing support column 5; to a certain extent, it is beneficial to the seismic isolation and durability of the spring shock-absorbing support column 5.

[0033] Specifically, in this embodiment, there is a certain distance between the groove 10 of the steel column and the rotary lifter 3, and the groove 10 and the rotary lifter 3 are both on the same horizontal line vertically and horizontally; in normal use, they do not participate in bearing loads.

[0034] The infrared ranging transmitter 2 is located below the upper seat plate 12, and the infrared ranging receiver 4 is located above the lower base plate 13. The two are on the same horizontal line vertically and horizontally to ensure the normal and accurate use of the rangefinder; the infrared ranging receiver 4 is located at the bottom of the rotary lifter 3 and is connected as a whole.

[0035] The distance display screen 8 is located outside the infrared distance measuring receiver 4, and the connecting gap is connected by epoxy resin adhesive. The distance display screen 8 can achieve the characteristics of convenient recording and convenient operation.

[0036] The infrared transmitter 15 is equipped with an infrared transmitting lamp, a circuit board, and a battery. By setting a fixed program, it can emit infrared rays all day or at a fixed time. The infrared transmitting lamp is an energy-saving LED, which has the characteristics of low energy consumption and long service life; the battery adopts a lithium battery, which has the characteristics of long life, stable discharge, high safety, etc.; the infrared receiver 16 receives the infrared signal from the infrared transmitter 15 and converts it into an electrical signal, which is transmitted to the microprocessor 17 through the circuit. The microprocessor 17 has a calculation program and a timing setting. The distance can be calculated by the arrival time, the set time and the propagation speed of infrared in the air, and the calculated distance is subtracted from the set distance. The time required to start the motor is calculated by the difference, and finally the data is output in sequence and transmitted to the micro-judge 19. The micro-judge 19 has a judgment program that can process and judge whether to start the rotating motor to drive the rotating column 18 to rise and fall.

[0037] The microprocessor 17 transmits the calculated distance to the distance display screen 8 through the circuit, and the distance display screen 8 converts the electrical signal into an optical signal and displays it on the screen for personnel to record and test.

[0038] If the micro-judgment device (including motor) 19 determines that the rotating motor needs to be started to drive the rotating column 18 to move up and down, the rotating column 18 contacts the groove 10 through the lifting and lowering. At this time, the rotating column 18 starts to adjust the displacement and bear the load; when the predetermined time is reached, the rotating column 18 stops working.

[0039] Both the microprocessor 17 and the microdeterminator 19 can enter the manual setting mode, and the free lifting and lowering function of the rotating column 18 can be realized by manually increasing the starting motor time, which is conducive to achieving fast and efficient support replacement.

[0040] The damping column 20, the damping spring 21 and the hollow sleeve 22 are all made of structural steel, and have the characteristics of high strength, high toughness and good processability. The top of the damping column 20 is provided with an anchor hole for convenient installation and connection; the damping spring 21 is nested between the damping column 20 and the hollow sleeve 22. When the damping column 20 is subjected to load and displaced, the damping spring 21 begins to be subjected to force. Since the damping spring 21 has good elastic deformation and reset function, the damping spring 21 applies a reaction force upward, which can buffer the load impact and assist the damping column 20 in bearing the load; when the damping spring 21 is subjected to force, the hollow sleeve 22 can limit the lateral displacement of the lower part of the damping spring 21 caused by compression energy storage, so that the elastic potential energy of the damping spring 21 is fully applied to the buffer gasket 9 and the upper seat plate 12, thereby maximizing its role; the damping column 20, the damping spring 21 and the hollow sleeve 22 can work together to greatly improve the vertical ultimate bearing capacity of the support, and ensure that the support has better seismic isolation and vibration reduction properties.

[0041] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
