Description

Technical Field

[0001] The present invention belongs to the technical field of bridge settlement measurement, and specifically refers to a device for detecting the settlement deformation of the arch bridge deck. Background Art

[0002] The arched bridge deck is a curved surface structure. According to its own characteristics, lidar technology is generally used to generate a three-dimensional model for the overall settlement analysis of complex arched structures. However, in this process, the upfront investment cost for the observation of a single project is huge, and later, regular manual maintenance of the reference points is required, resulting in continuously increasing subsequent costs. The detection cost is high, and it is impossible to achieve wide popularization. Summary of the Invention

[0003] In view of the above situation, the present invention provides a device for detecting the settlement deformation of the arch bridge deck, which is installed at the expansion joint of the arch bridge. By measuring the sliding distance of the lateral drag displacement measuring part in the settlement value measuring plate part, the force conditions in multiple dimensions are recorded. And through the vertical shock absorption blocking part and the inclined buffer member, the tiny tremors applied to the vertical shock absorption blocking part are eliminated, preventing the tiny vibrations from being transmitted to the built-in processing plate part and causing fatigue damage to the precision components, prolonging the service life of the components. And this device does not require power drive and will carry out restricted linkage by itself after installation.

[0004] Subsequently, by reading the content data in the information processing board of the device, the practicality of the device of the present invention is greatly improved. It has low requirements for external conditions and low operating costs, and can realize the large-scale use of the device. After large-scale popularization, it can be read regularly, which is convenient for centralized observation and inspection of key projects in the later stage.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a device for detecting the settlement deformation of the arch bridge deck, including a vertical shock absorption blocking part, an inclined buffer member, a lateral drag displacement measuring part and a settlement value measuring plate part. The vertical shock absorption blocking part is rotatably connected to the inclined buffer member, the lateral drag displacement measuring part is rotatably connected to the inclined buffer member, and the lateral drag displacement measuring part is inserted and slidably connected to the settlement value measuring plate part; The vertical shock absorption blocking part includes a top fixed shock absorption shaft part, a bottom wrapped pipe part and a mounting clamping part. The top fixed shock absorption shaft part is inserted into the bottom wrapped pipe part, and the mounting clamping part is clamped to the outer wall of the vertical shock absorption blocking part; The inclined buffer member includes a buffer insertion part and an inclined drag long rod. The two ends of the buffer insertion part are respectively rotatably connected to the top fixed shock absorption shaft part and the inclined drag long rod; The lateral dragging displacement measuring member includes a numerical value measuring pipe member, a traction reset pipe member and a sliding moving member. One end of the numerical value measuring pipe member and the traction reset pipe member is rotatably connected to the inclined dragging long rod, and the other end of the numerical value measuring pipe member and the traction reset pipe member is fixedly connected to the sliding moving member. The sliding moving member slides within the settlement numerical value measuring plate member.

[0006] In the device of the present invention, there are two sets of vertical shock absorption blocking members, inclined buffer members and lateral dragging displacement measuring members. The top fixed shock absorption shaft member and the bottom wrapping pipe member are positioned through the installation clamping member to ensure the overall stability of the device. Through the mutual restriction of the angles between the members, the precise measurement of the settlement displacement is ensured under the stable state of the device, preventing the locking of parts due to the displacement of the members during the measurement process, resulting in the loss of authenticity of the measurement data.

[0007] Further, the top fixed shock absorption shaft member includes a connecting fixed shaft, a sliding connecting shaft member and a follower pipe. The sliding connecting shaft member is fixedly arranged at the bottom of the connecting fixed shaft, and the follower pipe is fixedly arranged at the bottom of the connecting fixed shaft. The follower pipe and the sliding connecting shaft member are arranged concentrically. The sliding connecting shaft member moves in and out of the bottom wrapping pipe member. The sliding connecting shaft member includes an inserted thin shaft and a sliding shaft. The upper end of the inserted thin shaft is fixedly connected to the lower end of the connecting fixed shaft. A wrapping spring is wrapped outside the inserted thin shaft. The upper end of the sliding shaft is fixedly connected to the lower end of the inserted thin shaft. Side fixed blocks are fixedly arranged on both sides of the sliding shaft. The follower pipe wraps around the upper end of the bottom wrapping pipe member, and an internal induction ring is fixedly arranged on the inner wall of the follower pipe.

[0008] In the device proposed in this aspect, the sliding ring member moves repeatedly within the sensing range of the internal induction ring, and it is not necessary to record the vibration running track among them. When the sliding ring member breaks away from the sensing range of the internal induction ring, an alarm is issued to notify the material expansion or bulging of the bridge deck.

[0009] Preferably, a sliding ring member is fixedly arranged on the outer wall of the upper end of the bottom wrapping pipe member, and an inner wall clamping groove is formed on the inner wall of the bottom wrapping pipe member. The side fixed blocks slide within the inner wall clamping groove.

[0010] As a further preference of the present invention, the installation clamping member includes a clamping arc plate and a clamping cross plate. There are two clamping arc plates, and the two clamping arc plates are fixedly arranged on the bottom surface of the clamping cross plate.

[0011] Furthermore, the buffer insertion component includes an insertion rod and a buffer tube. One end of the insertion rod is rotatably connected to the shaft body of the connecting fixed shaft, and the other end of the insertion rod is inserted and slid within the buffer tube. The tail end of the buffer tube is rotatably connected to the rod body of the inclined dragging long rod. One end of the inclined dragging long rod is rotatably connected to the lower end of the bottom wrapping pipe fitting, and the other end of the inclined dragging long rod is rotatably connected to one end of the numerical measurement pipe fitting.

[0012] When the top fixed shock-absorbing shaft component proposed in the device of the present invention encounters slight tremors, the sliding connection shaft component moves through insertion within the bottom wrapping pipe fitting. To prevent the tremor force from being transmitted to the settlement numerical measurement plate component, the buffer insertion component dissipates the tremor force, avoiding the repeated meaningless small sliding of the measurement induction strip on the built-in processing plate component, which may cause fatigue damage to precision components.

[0013] Preferably, an internal measurement ring component is fixedly connected to the inner wall of the numerical measurement pipe fitting, and a support spring and a return spring are fixedly connected within the traction return pipe fitting.

[0014] As a further preference of the present invention, the sliding moving component includes an induction component, a dragging component, and a sliding plate. The induction component is inserted within the numerical measurement pipe fitting, the dragging component is inserted within the traction return pipe fitting. The tail ends of the induction component and the dragging component are fixedly connected to the outer surface of the sliding plate facing outward. The induction component includes a connecting shaft A and an induction plate. The induction plate is fixedly connected to the front end of the connecting shaft A. The tail end of the connecting shaft A is fixedly connected to the outer surface of the sliding plate facing outward. An enclosing induction ring is fixedly connected in a ring shape to the outer wall of the induction plate, and the enclosing induction ring slides within the range of the internal measurement ring component.

[0015] Furthermore, the dragging component includes a connecting shaft B and a dragging plate. The front end of the connecting shaft B is fixedly connected concentrically with the dragging plate. The support spring is fixedly connected between the dragging plate and the inner top surface of the traction return pipe fitting. The return spring is wrapped around the outside of the connecting shaft B. The tail end of the connecting shaft B is fixedly connected to the outer surface of the sliding plate facing outward.

[0016] Preferably, a measurement induction strip is fixedly connected to the inner surface of the sliding plate facing inward.

[0017] As a further preference of the present invention, the settlement numerical measurement plate component includes a measurement plate body, a sliding measurement notch, a built-in processing plate component, and an information processing plate. Fixed insertion anchor bolts are fixedly connected to the back of the measurement plate body. A sliding measurement notch is formed on the outer surface of the measurement plate body. The measurement induction strip slides on the built-in processing plate component. The built-in processing plate component is fixedly connected within the sliding measurement notch. An information processing plate is fixedly connected within the measurement plate body. The built-in induction ring, the internal measurement ring component, and the built-in processing plate component are all signal-connected to the information processing plate.

[0018] During the daily monitoring process, the device of the present invention does not need to be connected to a power source or power, and uses the physical structure to restrict and affect each other to read the information in the information processing board. By measuring the moving distance of the wrapped induction ring within the built-in measuring ring member and the moving distance of the induction strip on the built-in processing board member, a multi-angle and multi-dimensional comprehensive analysis of the settlement deformation of the arch bridge deck is carried out to improve the accuracy of the detection results.

[0019] The beneficial effects achieved by the present invention with the above structure are as follows: (1). There are two sets of vertical shock-absorbing blocking members, inclined buffer members and horizontal drag displacement measuring members in the device of the present invention. The top fixed shock-absorbing shaft member and the bottom wrapped pipe member are positioned through the installation clamping member to ensure the overall stability of the device. Through the mutual restriction of the angles between the members, the precise measurement of the settlement displacement is ensured under the stable state of the device, and it is prevented that during the measurement process, the locking between parts occurs due to the displacement of the members, resulting in the loss of authenticity of the measurement data.

[0020] (2). The sliding ring member proposed in this device moves repeatedly within the induction range of the built-in induction ring. There is no need to record the vibration running track among them. When the sliding ring member breaks away from the induction range of the built-in induction ring, an alarm is issued to report the material expansion or bulging of the bridge deck.

[0021] (3). When the top fixed shock-absorbing shaft member in the device of the present invention encounters a slight tremor, the sliding connection shaft member moves through the bottom wrapped pipe member. In order to prevent the tremor force from being transmitted to the settlement value measuring board member, the tremor force is dissipated through the buffer plug-in to avoid the meaningless small sliding of the measuring induction strip on the built-in processing board member repeatedly, causing fatigue damage to the precision components.

[0022] (4). During the daily monitoring process, the device of the present invention does not need to be connected to a power source or power, and uses the physical structure to restrict and affect each other to read the information in the information processing board. By measuring the moving distance of the wrapped induction ring within the built-in measuring ring member and the moving distance of the induction strip on the built-in processing board member, a multi-angle and multi-dimensional comprehensive analysis of the settlement deformation of the arch bridge deck is carried out to improve the accuracy of the detection results.

[0023] (5). During the initial installation process of the device of the present invention, the requirements for the installation personnel are not high, the installation steps are simple, and the installation process is fast.

[0024] (6). The analysis process proposed by the device of the present invention mainly uses the deformation distance, so there are only requirements within a range for the initial contact position, and no precise calibration requirements are made, which greatly reduces the installation accuracy requirements in the early stage.

[0025] (7) This device does not require power drive. After installation, it will carry out restricted linkage by itself. Subsequently, the content data in the information processing board is read through the device, which greatly improves the practicability of the device of the present invention. It has low requirements for external conditions and low operating costs, and can realize the large-scale use of the device. After large-scale popularization, it can be read regularly, which is convenient for centralized observation and inspection of key projects in the later stage. Description of the Drawings

The built-in induction ring 24, the built-in measurement ring member 31, and the built-in processing plate member 15 are all signal-connected to the information processing plate 16.

[0041] During specific use, the device of the present invention is installed at the expansion joint of the arch bridge deck. The vertical shock-absorbing and blocking member 1 is inserted and installed on one side of the expansion joint, the settlement value measurement plate member 4 is installed on the other side of the expansion joint, and the inclined buffer member 2 and the lateral drag displacement measurement member 3 are arranged in the expansion joint interval. Multiple-point installation can be carried out according to actual needs in the same expansion joint.

[0042] The engaging arc plate 27 of the mounting engaging part 7 is engaged at the upper and lower end parts of the two vertical shock-absorbing and blocking parts 1. Among the two vertical shock-absorbing and blocking parts 1, first fix one. The upper end of the connecting fixed shaft 17 is fixed to one side of the expansion joint of the arch bridge by passing an expansion bolt through the engaging cross plate 28 and the upper end part of the connecting fixed shaft 17. Then, through a vertical angle detection device such as a laser collimator, ensure that one of the vertical shock-absorbing and blocking parts 1 is in a vertical state, and then pass an expansion bolt through the engaging cross plate 28 and the lower end part of the bottom wrapping pipe fitting 6 and fix it to penetrate into the expansion joint. Then fix the other vertical shock-absorbing and blocking part 1. During the installation of the vertical shock-absorbing and blocking part 1, in addition to ensuring that the central axes of the top fixed shock-absorbing shaft part 5 and the bottom wrapping pipe fitting 6 are on the vertical line, avoid manually dragging the bottom wrapping pipe fitting 6 to prevent a large range of deviation of the central position of the sliding ring part 25 in the built-in induction ring 24, and artificially shorten the sliding distance of the sliding ring part 25. Compare the height of the settlement value measuring plate part 4 with the sliding plate 36 of the sliding moving part 12, and try to place the sliding plate 36 at the middle position of the sliding measurement notch 14. The fixed insertion anchor bolts 43 of the measurement plate body 13 penetrate into the other side of the expansion joint and are fixed. After completing the installation work, connect the information processing board 16 and mark each initial data. Mark the initial contact position of the wrapping induction ring 39 and the built-in measurement ring part 31 as A1, and mark the initial position where the measurement induction strip 42 contacts the built-in processing board part 15 as B1. Determine that the sliding ring part 25 is within the induction range C of the built-in induction ring 24. Due to minor differences in the installation process, each set of devices has its own corresponding initial data values, and there is no unified rigid requirement.

[0043] After installation and commissioning, when a slight vibration occurs above the top fixed shock-absorbing shaft part 5, it is transmitted to the sliding connecting shaft part 18 through the connecting fixed shaft 17. The inserting thin shaft 20 and the sliding shaft 21 are inserted and pulled in the bottom wrapping pipe fitting 6, and the side fixing block 23 is engaged and moved in the inner wall engaging groove 26. During the sliding of the follower pipe 19, the sliding ring part 25 is passively slid in the built-in induction ring 24. During the process of the top fixed shock-absorbing shaft part 5 being pulled and inserted, the inserting rod 29 is inserted and pulled within a small range in the buffer pipe 30 to prevent the vertical shock-absorbing and blocking part 1 and the inclined buffer member 2 from being locked due to their triangular structures; when a large vibration occurs at the vertical shock-absorbing and blocking part 1, the vertical shock-absorbing and blocking part 1 itself undergoes an overall position movement, and the inclined buffer member 2 drags the horizontal dragging displacement measuring member 3 to move up and down. The numerical value measuring pipe fitting 10 and the traction reset pipe fitting 11 move up and down along with the inclined dragging long rod 9. The sliding moving part 12 is inserted and slid in the settlement numerical value measuring plate part 4, and the measurement induction strip 42 of the sliding plate 36 slides on the built-in processing board part 15, and the contact position changes. After the vibration ends, it is reset under the support and reset influence of the wrapping spring 22, the support spring 32, and the reset spring 33, and the information processing board 16 is read regularly later.

[0044] The sliding ring member 25 is continuously inside the sensing range C of the built-in sensing ring 24. When the settlements on both sides of the expansion joint are inconsistent, it is measured that the contact position between the sensing strip 42 and the built-in processing plate member 15 changes to B2. And because the bridge deck of the arch bridge is an arch structure, that is, when the settlements on both sides of the expansion joint are completely consistent, the sensing member 34 moves inside the numerical measurement pipe member 10, and the contact position of the wrapped sensing ring 39 inside the built-in measurement ring member 31 is A2. Therefore, when reading the data, it is necessary to combine the initial data A1 and B1, the data A2 and B2 during reading, and count the deformation data A' (the positive and negative numerical difference between A2 and A1) and B' (the positive and negative numerical difference between B2 and B1), and then conduct a unified analysis of the settlement deformation situation. When the data shows that the settlement deformation situation is serious, closely monitor the target sample and conduct further observation and monitoring; when the sliding ring member 25 slips outside the sensing range C of the built-in sensing ring 24, it indicates that the side where the vertical shock absorption blocking member 1 is installed has expansion deformation, posing a serious safety hazard.

[0045] The above is the overall working process of the present invention. Just repeat these steps when using it next time.
