The specific embodiments described herein are merely illustrative of the application and are not intended to limit the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application provides a monitoring device suitable for a seamless bridge expansion joint, which is shown in fig. 1-4 as a structural diagram. In a specific embodiment of the present application, the monitoring device includes a recognition mechanism 3, the recognition mechanism 3 is used for recognizing that a crack occurs between the bridge plate 1 and the elastic filler 2, and the recognition mechanism 3 includes: male member 31, female member 32, control module 5 and pressure sensor 35. Wherein, the convex part 31 is fixed in the groove formed on the side surface of the bridge plate 1 close to the elastic filling body 2, and the convex part faces to the direction of the elastic filling body 2.
The concave part 32 is provided on the side of the elastic packing body 2 corresponding to the convex part 31, and the groove of the concave part 32 faces the direction of the convex part 31. The concave part 32 is matched with the convex part 31, namely, the convex part can extend into the groove, and the convex part of the convex part 31 can be pressed at the bottom of the groove of the concave part 32.
The bottom of the concave part 32 is fixedly provided with a supporting rod 33, and the lower end of the supporting rod 33 is propped against a step surface of the bridge plate 1 extending towards the lower part of the elastic filling body 2, so as to position and support the concave part 32 when the elastic filling body 2 is poured.
At least one pressure sensor 35 is provided on the end face of the male member 31 that contacts the female member 32. When the convex portion of the male member 31 is pressed against the bottom of the concave groove of the female member 32, the pressure sensor 35 detects a certain pressure value. When the male member 31 and the female member 32 are gradually separated, the pressure value detected by the pressure sensor 5 gradually decreases to 0.
As shown in fig. 5, the monitoring device further comprises a control module 5, wherein the control module 5 is arranged in the control box and is electrically connected with the pressure sensor 35. The control box is generally fixedly arranged on the side edge of the bridge plate or other parts of the bridge. The control module 5 can determine whether the male member 31 and the female member 32 are separated from each other or not based on the data of the pressure sensor 35 and the distance measuring sensor 36, and whether a crack occurs between the bridge plate 1 and the elastic packing body 2 or not.

In this embodiment, the communication module 6 includes a Wifi component and a GPRS component. The Wifi component can be connected with the mobile terminal equipment on site, so that monitoring data of the device can be conveniently checked. The GPRS component can be used for carrying out data transmission with a background database by inserting the SIM card, so that the real-time uploading of monitoring data is realized.
In the specific embodiment of the application, the monitoring device further comprises a repairing mechanism 4, wherein the repairing mechanism 4 is arranged inside the elastic filling body 2, and the repairing mechanism 4 is communicated with a through groove 34 formed in the middle of the bottom of the groove of the concave part 32. When the concave part 32 and the convex part 31 are pressed, the convex part of the convex part 31 can be pressed outside the through groove 34, so that the through groove 34 is prevented from communicating with the groove. In a state where the concave member 32 and the convex member 31 are out of contact, the through groove 34 communicates with the inside of the groove, and the repairing mechanism 4 can repair the crack occurring between the bridge plate 1 and the elastic filler 2.
In the use process of the bridge expansion device, the adhesive force of the elastic filling body 2 can be reduced along with the aging of materials, tiny cracks can appear, and finally the large cracks are enlarged. Therefore, when tiny cracks appear, the detection, discovery and timely treatment are needed, and the situation that the cracks suddenly expand into large cracks and the gaps between adjacent bridge slabs 1 are too large to cause traffic hazards is prevented. The present application fixes the male member 31 and the female member 32 to the bridge plate 1 and the elastic packing body 2, respectively, by being fitted with each other. The concrete installation steps are that firstly, an installation groove is cut on the side face of the bridge plate 1, and then the convex piece 31 is welded and fixed in the installation groove. The bottom of the bridge plate 1 extends perpendicular to the side surface, and finally forms a step shape. The matched concave part 32 is pressed against the step surface of the bridge plate 1 through the support rod 33 at the bottom of the concave part, and the pressure sensor 35 on the convex part 31 is attached to the groove bottom of the concave part 32. The elastic filling body 2 is heated and then poured into the expansion joint layer by layer, so that the support rods 33 are wrapped and formed into a whole by the elastic filling body 2 to realize primary fixation, and the manual pressing force concave piece 32 can be removed. Further, the elastic filler 2 is continuously cast so that the concave piece 32 and the elastic filler 2 form an integral structure. The side surfaces of the bridge plate 1 are coated with an adhesive, so that the cooled elastic filling body 2 is tightly connected with the bridge plate 1. When the elastic filler 2 is aged during cold shrinkage, the adhesion between the side surface and the bridge plate 1 is reduced to form a gap, and at this time, the contact end surfaces of the male member 31 and the female member 32 respectively provided on the bridge plate 1 and the elastic filler 2 also form a gap, so that the pressures of the plurality of distributed pressure sensors 35 are weakened or vanished. The pressure sensor 35 feeds back pressure data to an external control end, and the control end judges that the expansion joint is abnormal, so that the purpose of monitoring the expansion joint in real time is achieved, the accuracy and timeliness of a monitoring result are ensured, and the driving safety is improved.
Furthermore, when the crack appears between the bridge plate 1 and the elastic filling body 2, the repairing mechanism 4 can temporarily repair the internal crack, so that the buffering time is won for the overhauling personnel to replace the elastic filling body 2 of the local expansion joint.
In the specific embodiment of the application, the repairing mechanism 4 comprises a repairing bin 41, the repairing bin 41 is paved along the length direction of the elastic filling body 2, and the inside of the repairing bin 41 is filled with the adhesive with pressure. In this embodiment, the color of the adhesive is yellow or red, which is convenient for maintenance personnel to check.
The two sides of the repairing bin 41 are provided with hoses 42, and the hoses 42 are inserted into the through grooves 34 and communicated with each other, so that the adhesive is led to the crack between the bridge plate 1 and the elastic filler 2 through the through grooves 34, and the crack is temporarily repaired. In this embodiment, a plurality of convex parts 31 are disposed on the side wall of the bridge plate 1, a plurality of concave parts 32 are disposed in the corresponding elastic filling body 2, and the number of hoses 42 on two sides of the repairing bin 41 corresponds to the number of concave parts 32 and are connected in a one-to-one correspondence.
Further, a check valve is provided in the hose 42, and the check valve enables the pressured adhesive in the repair bin 41 to be led out into the through groove 34 in one direction.
The repairing mechanism 4 is installed by placing the repairing bin 41 in a horizontal position with the concave part 32 and then plugging and matching the hose 42 with the through groove 34. The cast elastic filling body 2 connects the three parts into a whole, and when the repairing bin 41 is covered to the three-quarter position, the adhesive with pressure is led in from the leading-in mouth of the repairing bin 41 through an external conveying device, so that the installation of the repairing mechanism 4 is completed. Because the convex part 31, the concave part 32 and the hose 42 are matched and provided in a plurality, and are distributed at equal intervals along the length direction of the expansion joint, the repairing mechanism 4 can temporarily repair each expansion joint.
The convex part of the convex part 31 fully presses and seals the port of the through groove 34 of the concave part 32 in the initial state, and the adhesive cannot enter the groove through the through groove 34. When the crack is formed, the male part 31 and the female part 32 are separated, the port of the through groove 34 is opened, and the adhesive with pressure in the repairing bin 41 overflows into the groove from the port of the through groove 34 through the one-way valve until the crack is overflowed and filled. The supplementary repair function of the adhesive is fully utilized, so that the adhesion degree between the elastic filler 2 and the bridge plate 1 is increased. On the one hand, the small cracks can be repaired, the cracks are slowed down to become larger, and the driving safety is improved. On the other hand, the crack at the larger part in the expansion joint can be repaired in an emergency, the effective use time of the crack is prolonged, and the buffer time is won for overhauling personnel to replace the elastic filling body 2 of the local expansion joint.
In the specific embodiment of the application, the lower half part of the repairing bin 41 is also provided with a self-jacking component 43, and the self-jacking component 43 is used for adjusting the volume in the repairing bin 41 according to the volume of the adhesive, keeping the filling state of the adhesive in the repairing bin 41 and providing pressure for extruding the adhesive.
Further, the self-jacking assembly 43 includes: an elastic layer 431, a web 432, and an elastic member 433. The periphery of the elastic layer 431 is fixedly connected to the side wall of the repair bin 41, and the peripheral fixed height of the elastic layer 431 is equal to or slightly lower than the lowest height of the connection port of the hose 42.
The connection plate 432 is fixedly connected with the middle part of the elastic layer 431. The length of the web 432 should be slightly less than the length of the repair cartridge 41.
The top of the elastic piece 433 is fixedly connected with the bottom of the connecting plate 432, and the bottom of the elastic piece 433 is fixedly connected with the bottom of the repairing bin 41 and is used for providing elastic thrust to upwards extrude the elastic layer 431. In this embodiment, at least one elastic member is disposed within the repair cartridge 41. Preferably, the elastic member is a spring.
When the adhesive in the repairing bin 41 overflows, the upper plane of the adhesive is gradually lower than the position where the hose 42 is connected, and the adhesive cannot overflow at the moment, so that the rest adhesive is wasted, and the self-ejecting assembly 43 assists the overflow of the adhesive. Specifically, when the adhesive is injected, the adhesive under pressure presses the bottom elastic layer 431, so that the middle portion of the elastic layer 431 is deformed and presses the bottom elastic member 433 to move downward. In the process of overflowing the adhesive, the pressure from the adhesive applied to the elastic piece 433 is reduced, so that the elastic layer 431 is pushed to move upwards in a rebound manner, and then the adhesive is always in a full state under the pushing of the elastic layer 431, so that sufficient overflowing is realized, and the waste of the adhesive is reduced.
In a specific embodiment of the application, at least one distance measuring sensor 36 is provided on the side of the bulge of the male element 31. In this embodiment, the ranging sensor is a laser ranging sensor.
In this embodiment, the bottom area of the groove of the concave part 32 is smaller than the opening area, the sidewall of the groove is an arc transition surface or a straight transition surface, and the distance measuring sensor 36 can feed back the distance value between the distance measuring sensor 36 and the sidewall of the groove of the concave part 32 in real time when the convex part 31 and the concave part 32 are relatively displaced. The distance values can be transferred to a background database via the communication module 6 and a line graph of the distance data can be formed on the display screen. When the male member 31 and the female member 32 are kept in contact, the position of the point emitted to the inner wall of the groove per unit time by the distance measuring sensor 36 is kept unchanged, and the distance line graph thereof is maintained in a straight line. When the expansion joint is cracked, the convex part 31 and the concave part 32 are separated from contact, at this time, the point of the convex part 31, where the ranging sensor 36 emits to the side wall of the groove, will be relatively displaced relative to the concave part 32, and the distance line graph will be changed from a straight line state to a curve state, so that the occurrence and change of the crack of the expansion joint can be visually displayed. Further, in combination with an abnormality in feedback from the pressure sensor 35, it is explained that the disengagement between the male member 31 and the female member 32 is necessarily occurring. When only the pressure sensor detects a decrease in pressure, it is not necessarily in the disengaged state. The accuracy of testing result has been guaranteed to dual monitoring data, and every monitoring point all has corresponding distance line graph, and maintainer can confirm the position that needs to overhaul fast, promotes the efficiency of overhaul.
In an embodiment of the present application, as shown in fig. 5, the monitoring device further includes: a power supply module 7, a positioning module 8 and a warning lamp 9.
