Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, and in particular to an automatic traveling bridge construction flatness detection device. Background Art

[0002] Bridge deck pavement refers to the protective layer laid on the bridge deck to prevent direct wear of the bridge deck by the wheels, spread the wheel load, and provide a smooth and non-slip driving surface for vehicles. Increasing the thickness of the bridge deck pavement generally does not enhance the overall stiffness of the bridge structure, but increases the dead load of the bridge. Especially for large-span bridges, the weight of the bridge deck pavement may have a significant impact on the economic efficiency of the bridge. Therefore, the thickness of the bridge deck pavement needs to be precisely controlled, and the flatness of the bridge deck needs to be tested after the bridge construction is completed.

[0003] Currently, the commonly used methods for detecting bridge deck flatness include the fixed-length ruler method, the shell excitation method, the radar measurement method, and the laser scanning method. Among them, the shell excitation method is only suitable for short-distance bridge deck detection and requires a special vehicle to cooperate. The radar measurement method and the laser scanning method are relatively expensive and require the detection personnel to have certain technical literacy. Therefore, the fixed-length ruler method is used. However, the fixed-length ruler method requires manual placement of a ruler on the bridge deck and strict measurement of multiple points for a long time according to the point spacing. Each point requires at least 10 consecutive measurements, which makes the measurement of bridge deck flatness time-consuming and labor-intensive, and it is difficult to ensure data accuracy. For this reason, an automatic traveling bridge construction flatness detection device is proposed. Summary of the Invention

[0019] 5. The present invention provides a lubricating oil bottle so that when the stylus pen is stored in the storage slot and remains aligned with the docking sleeve, the stylus electric push rod drives the stylus pen to move and dock with the docking sleeve, thereby connecting the control tube.

[0034] like Figures 1 to 9 As shown, an automatic traveling bridge construction flatness detection device includes a self-propelled trolley 1, as shown in FIG. Figure 1 As shown, a horizontal slide rail 2 is fixedly installed on one side of the self-propelled trolley 1. Figure 2 As shown, a horizontally arranged traveling screw 3 is rotatably installed inside the horizontal slide rail 2, a traveling motor 4 is fixedly installed at one end of the horizontal slide rail 2, and the output shaft of the traveling motor 4 is drivingly connected to one end of the traveling screw 3. A traveling slider 6 is slidably installed inside the horizontal slide rail 2, and a horizontally arranged traveling guide rod 5 is fixedly installed inside the horizontal slide rail 2. A threaded hole is opened on the traveling slider 6, and the traveling slider 6 is screwed on the traveling screw 3. The traveling guide rod 5 is slidably connected to the traveling slider 6, as shown in FIG. Figure 3 As shown, an inner slider 7 is fixedly mounted on one side of the traveling slider 6, and multiple lubricating balls 8 are rotatably mounted on both sides of the inner slider 7 and are evenly distributed from top to bottom. Figure 2 As shown, a lifting slide 9 is provided on one side of the inner slide 7. Figure 4As shown, vertically arranged rolling tracks 901 are provided on the inner walls of both sides of the lifting slide 9, and a plurality of lubricating balls 8 on both sides are respectively located inside the two rolling tracks 901. In this embodiment, the lifting slide 9 is a U-shaped structure, which is sleeved on the inner slider 7 but does not contact the inner slider 7. It only contacts the lubricating balls 8 through the rolling tracks 901 on both sides. The lubricating balls 8 cooperate with the rolling tracks 901 to make the inner slider 7 and the lifting slide 9 slideably connected to each other, and greatly improve the lubrication between the lifting slide 9 and the inner slider 7. A wheel frame 10 is fixedly installed at the bottom end of the lifting slide 9, and a horizontally arranged detection wheel 11 is rotatably installed at the bottom of the wheel frame 10. The axis of the detection wheel 11 is perpendicular to the axis of the traveling screw 3, and a trajectory depicting component for concretely recording the travel trajectory of the detection wheel 11 is provided at the bottom of the horizontal slide rail 2; specifically, the automatic traveling bridge construction flatness detection device is used When the bridge is cleared, the staff will first clean the bridge deck to prevent debris from affecting the detection accuracy of the device. The self-propelled trolley 1 carrying the horizontal slide rail 2 and the track drawing component starts to move in a direction parallel to the bridge and stops on the bridge deck. At this time, the travel motor 4 drives the travel screw 3 to start rotating, thereby driving the travel slider 6 to slide inside the horizontal slide rail 2, thereby driving the detection wheel 11 to move on the bridge deck in a direction perpendicular to the travel direction of the self-propelled trolley 1 through the inner slider 7 and the lifting slide 9, so that the detection wheel 11 rolls on the bridge deck, thereby judging the current flatness of the bridge deck with the help of the up and down amplitude of the detection wheel 11 during the rolling process, and making a concrete record with the help of the track drawing component. When the detection wheel 11 travels to the maximum stroke, the self-propelled trolley 1 continues to move the unit distance, so that the detection wheel 11 starts to return and carries out the second round of detection, thereby realizing fast and accurate fully automatic detection of the flatness of the bridge deck.

[0035] like Figure 1 、 Figure 6 As shown, the track drawing component includes an electronic touch pressure sensing plate 12 arranged at the bottom of the horizontal slide rail 2. The electronic touch pressure sensing plate 12 is horizontally arranged and fixedly mounted on one side of the self-propelled trolley 1, as shown in FIG. Figure 5 As shown, a horizontally arranged touch-pressure electric push rod 13 is fixedly installed on the inner wall of the lifting slide 9, and the telescopic end of the touch-pressure electric push rod 13 faces the electronic touch-pressure sensing plate 12 and is fixedly installed with a touch-pressure pen 14, as shown in FIG. Figure 6 As shown, the top and bottom of the electronic touch pressure sensing plate 12 are fixedly installed with a winding long box 15, and the two winding long boxes 15 are symmetrically arranged. One end of the winding long box 15 is rotatably installed with an opening and closing door 16, and the other end of the winding long box 15 is fixedly installed with a winding and unwinding motor 18. Figure 7As shown, a patterned transmission rod 17 is rotatably installed inside the winding long strip box 15, and the patterned transmission rod 17 is driven and connected to the output shaft of the winding and unwinding motor 18. A winding sleeve 19 is slidably sleeved on the patterned transmission rod 17. A through hole is opened on the side where the two winding long strip boxes 15 are close to each other. The same protective film 20 is set inside the two through holes. The two ends of the protective film 20 are respectively wound on the two winding sleeves 19. In this embodiment, the protective film 20 is fixed to the two winding sleeves 19 by plugging or gluing. The pattern transmission rod 17 and the winding sleeve 19 are fixedly connected and then wound up. A rotating frame for hanging the pattern transmission rod 17 and one end of the winding sleeve 19 is installed on the inner wall of the opening and closing door 16, so that the pattern transmission rod 17 and the winding sleeve 19 are kept balanced. Specifically, by setting a trajectory drawing component, before driving the detection wheel 11 to roll for detection, the touch-pressure electric push rod 13 will drive the touch-pressure pen 14 to move toward the protective film 20 and contact the protective film 20. During the movement of the detection wheel 11, if the detection wheel 11 encounters an uneven area, it will drive the lifting slide The frame 9 slides up and down, thereby driving the stylus 14 to make a wave-like movement on the protective film 20, thereby causing the internal electronic touch pressure sensing plate 12 to be pressurized and induced, drawing the rolling trajectory of the detection wheel 11, that is, the current outer curve of the bridge deck, thereby intuitively depicting the flatness of the bridge deck, and combining the movement of the self-propelled trolley 1 and the drive of the travel motor 4, each position of the curve is accurately recorded to achieve fast, accurate and automated flatness detection. By setting the protective film 20, during the operation of the device, the protective film 20 will always cover one side of the electronic touch pressure sensing plate 12 to protect the electronic touch pressure sensing plate 12. On the one hand, it prevents the stylus 14 from direct contact with the electronic touch pressure sensing plate 12, resulting in wear of the front end of the stylus 14 and scratches on the surface of the electronic touch pressure sensing plate 12. On the other hand, it can reduce the accumulation of dust and debris on the electronic touch pressure sensing plate 12, which affects the accuracy of curve drawing. At the same time, the staff can open the opening and closing door 16 at any time and replace the winding sleeve 19 and the protective film 20.

[0036] like Figure 6 As shown, the protective film 20 includes a protective layer 2001 arranged on the outermost side, and a carbon paper layer 2002 and a drawing paper layer 2003 are arranged on the inner side of the protective layer 2001 in sequence; specifically, by providing the protective film 20, the outermost protective layer 2001 can protect and moisture-proof the carbon paper layer 2002, the drawing paper layer 2003 and the electronic touch pressure sensing plate 12 of the inner layer, and the carbon paper layer 2002 and the drawing paper layer 2003 of the inner layer can cooperate with each other so that the pigment on the carbon paper layer 2002 draws the same curve on the drawing paper layer 2003 as the touch pen 14 is touched and pressed. The staff can tear open the two ends of the protective film 20 and separate the layers, take out the drawing paper layer 2003 and obtain a physical curve graph, compare it with the digitized curve graph, and facilitate the staff to use it on site.

[0037] like Figure 6 As shown, both sides of the electronic touch pressure sensing plate 12 are fixedly installed with horizontally set limit electric push rods 21, and the telescopic ends of the limit electric push rods 21 are fixedly installed with limit pressure plates 22, and the two limit pressure plates 22 are distributed on both sides of the protective film 20; specifically, by setting the limit pressure plates 22, when the rewinding motor 18 drives the protective film 20 to move on the electronic touch pressure sensing plate 12, the replacement of the coverage area of the electronic touch pressure sensing plate 12 is completed. At this time, the limit electric push rods 21 on both sides will drive the limit pressure plates 22 to cover both sides of the protective film 20 respectively, pressing the protective film 20 against the electronic touch pressure sensing plate 12 to prevent the protective film 20 and the electronic touch pressure sensing plate 12 from relative slipping, affecting the matching degree between the physical curve graph and the data curve graph, and greatly reducing the gap between the two, preventing external dust and debris from entering between the protective film 20 and the electronic touch pressure sensing plate 12.

[0038] like Figure 5 As shown, a horizontal lower sealing plate 23 is fixedly installed at the bottom of the touch-press electric push rod 13. Figure 8 As shown, the bottom of the inner slider 7 is provided with a receiving groove 701 adapted to the comfortable underwater sealing plate 23. Figure 3 As shown, both sides of the inner slider 7 are fixedly installed with vertically arranged suspension frames 24, and the top of the two suspension frames 24 is fixedly installed with the same lifting electric push rod 25, and the telescopic end of the lifting electric push rod 25 is vertically downward and fixedly installed with a clamping claw driver 26. The bottom drive of the clamping claw driver 26 is installed with two symmetrically arranged electric clamping claws 27. In this embodiment, the clamping claw driver 26 can adopt an electric linear actuator with a self-locking structure, such as a combination of a stepping motor and a double-headed screw and a screw sleeve. The double-headed screw is driven to rotate by the motor, driving the two screw sleeves to move in the opposite direction, thereby driving the two arc-shaped clamping claws 27 to perform the clamping action. The two electric clamping claws 27 are fixedly installed with a limited insert 28 on the side close to each other, as shown in FIG. Figure 4As shown, both sides of the top of the lifting slide 9 are provided with limit slots 902 that are compatible with the limit plugs 28; specifically, by setting the clamping claw driver 26, before the self-propelled trolley 1 moves, the lifting electric push rod 25 will drive the clamping claw driver 26 to descend to the top of the lifting slide 9. At this time, the clamping claw driver 26 drives the two electric clamps 27 to clamp the lifting slide 9 and make the limit plugs 28 on both sides respectively engage in the limit slots 902, so that the clamping claw driver 26 is engaged with the lifting slide 9. Then the lifting electric push rod 25 is reset, driving the lifting slide 9 to lift, so that the detection wheel 11 is off the ground, thereby preventing the detection wheel 11 from obstructing the movement of the self-propelled trolley 1 and preventing the detection wheel 11 from sliding friction with the ground and causing wear of the detection wheel 11. At the same time, the lifting electric push rod 25 drives the touch pressure electric push rod 13 to be retracted into the storage groove 701, so that the lower sealing plate 23 closes the bottom of the storage groove 701, thereby storing and protecting the touch pressure pen 14.

[0039] like Figure 8 As shown, a lubricating oil bottle 29 is fixedly installed on the top of the inner slider 7, and a lubricating oil pipe 30 connected to the lubricating oil bottle 29 is provided inside the inner slider 7. Figure 9 As shown, a horizontally arranged control tube 31 is fixedly installed at the bottom end of the lubricating oil pipe 30, one end of the control tube 31 is communicated with the inside of the threaded hole, and the other end of the control tube 31 is communicated with the inside of the receiving groove 701, a fixed slip ring 32 and a sealing ring 34 are fixedly installed inside the control tube 31, a control slide rod 33 is slidably installed inside the fixed slip ring 32, one end of the control slide rod 33 extends to the inside of the sealing ring 34 and is fixedly installed with a sealing disk 35 adapted to the sealing ring 34, the other end of the control slide rod 33 extends to the inside of the receiving groove 701 and is fixedly installed with a docking sleeve 37 adapted to the stylus 14, a return spring 36 is sleeved on the control slide rod 33, and both ends of the return spring 36 are respectively connected to the fixed slip ring 32 , the sealing ring 34 is fixedly connected; specifically, by providing the lubricating oil bottle 29, after the touch pen 14 is stored in the storage groove 701, the touch pen 14 will remain aligned with the docking sleeve 37, and the touch electric push rod 13 will drive the touch pen 14 to move and dock with the docking sleeve 37, thereby driving the control slide 33 to slide in the fixed slide ring 32, so that the sealing disk 35 is separated from the sealing ring 34, thereby connecting the control tube 31, and the lubricating oil inside the lubricating oil bottle 29 will flow into the threaded hole of the traveling slider 6 through the lubricating oil pipe 30 and the control pipe 31, and as the traveling slider 6 and the traveling screw rod 3 are engaged and transmitted, the traveling slider 6 and the traveling screw rod 3 are automatically lubricated and maintained, thereby extending the service life of the traveling screw rod 3.

[0040] like Figure 1As shown, two foldable dustproof cloths 38 are provided inside the horizontal slide rail 2, and the two foldable dustproof cloths 38 are distributed on both sides of the traveling slider 6, and one end of the two foldable dustproof cloths 38 is fixedly mounted on the inner walls of the two sides of the horizontal slide rail 2, and the other ends of the two foldable dustproof cloths 38 are respectively fixedly mounted on both sides of the traveling slider 6. Horizontally arranged limiting guide rails 39 are fixedly mounted on the top and bottom inner walls of the horizontal slide rail 2, and the traveling slider 6 is slidably connected to the limiting guide rails 39, and the top and bottom of the foldable dustproof cloth 38 extend to the inside of the two limiting guide rails 39 respectively; specifically, by providing the foldable dustproof cloths 38, the foldable dustproof cloths 38 on both sides will stretch or fold as the traveling slider 6 moves inside the horizontal slide rail 2, so that the traveling screw rod 3 inside the horizontal slide rail 2 is always within the coverage range of the foldable dustproof cloth 38, so that the foldable dustproof cloth 38 plays a protective and dustproof role for the traveling screw rod 3. At the same time, the limiting guide rails 39 on the upper and lower sides can limit the foldable dustproof cloth 38 to prevent the foldable dustproof cloth 38 from bending back and forth.

[0041] like Figure 4 As shown, a cleaning fan 40 is fixedly installed on the top of the wheel frame 10, and a first blast pipe 41 and a second blast pipe 42 are fixedly installed on both sides of the wheel frame 10, respectively. The first blast pipe 41 is connected to the output end of the cleaning fan 40, and an air supply pipe 43 is fixedly installed between the first blast pipe 41 and the second blast pipe 42; specifically, by arranging the cleaning fan 40, before the detection wheel 11 rolls for detection, the cleaning fan 40 will blow air toward the bridge deck on both sides through the first blast pipe 41 and the second blast pipe 42, so that the remaining fine dust, debris, etc. on the bridge deck are blown away, thereby further preventing the debris from affecting the detection accuracy of the device.

[0042] In summary: When the automatic traveling bridge construction flatness detection device is in use, the staff will first clean the bridge deck to prevent debris from affecting the detection accuracy of the device. The self-propelled trolley 1 carries the horizontal slide rail 2 and the track drawing component and starts to move in a direction parallel to the bridge and stops on the bridge deck. At this time, the traveling motor 4 drives the traveling screw 3 to start rotating, thereby driving the traveling slider 6 to slide inside the horizontal slide rail 2, thereby driving the detection wheel 11 to move on the bridge deck in a direction perpendicular to the travel direction of the self-propelled trolley 1 through the inner slider 7 and the lifting slide 9, so that the detection wheel 11 rolls on the bridge deck, thereby using the up and down amplitude of the detection wheel 11 during the rolling process to judge the flatness of the current bridge deck, and use the track drawing component to perform concrete When the detection wheel 11 reaches its maximum stroke, the self-propelled trolley 1 continues to move a unit distance, causing the detection wheel 11 to start its return journey and conduct a second round of detection, thereby realizing a fast and accurate fully automatic detection of the flatness of the bridge deck. By setting a trajectory drawing component, before driving the detection wheel 11 to roll for detection, the touch-pressure electric push rod 13 will drive the touch-pressure pen 14 to move toward the protective film 20 and contact the protective film 20. During the movement of the detection wheel 11, if the detection wheel 11 encounters an uneven area, it will drive the lifting slide 9 to slide up and down, thereby driving the touch-pressure pen 14 to make a wave-like stroke on the protective film 20, thereby causing the internal electronic touch-pressure sensing plate 12 to be pressurized and electrified, thereby drawing the rolling trajectory of the detection wheel 11, that is, the current bridge deck. The outer shape curve of the bridge surface can be intuitively depicted, and combined with the travel of the self-propelled trolley 1 and the drive of the travel motor 4, each positioning of the curve is accurately recorded to achieve rapid, accurate and automated flatness detection. By setting the protective film 20, during the operation of the device, the protective film 20 will always cover one side of the electronic touch pressure sensing plate 12 to protect the electronic touch pressure sensing plate 12. On the one hand, it can prevent the touch pen 14 from directly contacting the electronic touch pressure sensing plate 12, which may cause the front end of the touch pen 14 to be worn and the surface of the electronic touch pressure sensing plate 12 to be scratched. On the other hand, it can reduce the accumulation of dust and debris on the electronic touch pressure sensing plate 12, which may affect the accuracy of curve drawing. At the same time, the staff can open the protective film 20 at any time. Open and close the door 16 and replace the winding sleeve 19 and the protective film 20. By setting the protective film 20, the outermost protective layer 2001 can protect and moisture-proof the inner carbon paper layer 2002, the drawing paper layer 2003 and the electronic touch pressure sensing board 12. The inner carbon paper layer 2002 and the drawing paper layer 2003 can cooperate with each other so that the pigment on the carbon paper layer 2002 draws the same curve on the drawing paper layer 2003 as the touch pen 14 touches and presses. The staff can tear open the two ends of the protective film 20 and separate the layers, take out the drawing paper layer 2003 and obtain a physical curve graph, compare it with the digitized curve graph, and facilitate the staff to use it on site. By setting the limit pressure plate 22,When the rewinding and unwinding motor 18 drives the protective film 20 to move on the electronic touch pressure sensing plate 12, the replacement of the coverage area of the electronic touch pressure sensing plate 12 is completed. At this time, the limit electric push rods 21 on both sides will drive the limit pressure plates 22 to cover the two sides of the protective film 20 respectively, pressing the protective film 20 onto the electronic touch pressure sensing plate 12 to prevent the protective film 20 and the electronic touch pressure sensing plate 12 from relative slipping, affecting the matching degree between the physical curve graph and the data curve graph, and greatly reducing the gap between the two, preventing external dust and debris from entering between the protective film 20 and the electronic touch pressure sensing plate 12. By setting the claw driver 26, before the self-propelled trolley 1 moves, the lifting electric push rod 25 will drive the claw driver 26 to move down The lifting carriage 9 is lowered to the top of the lifting slide 9. At this time, the clamping claw driver 26 drives the two electric clamping claws 27 to clamp the lifting slide 9 and make the limit blocks 28 on both sides respectively clamp into the limit slots 902, so that the clamping claw driver 26 is clamped with the lifting slide 9. Then the lifting electric push rod 25 is reset, driving the lifting slide 9 to lift, so that the detection wheel 11 is off the ground, thereby preventing the detection wheel 11 from hindering the movement of the self-propelled trolley 1 and preventing the detection wheel 11 from sliding friction with the ground and causing wear of the detection wheel 11. At the same time, the lifting electric push rod 25 drives the touch-pressure electric push rod 13 to be stored in the storage groove 701, so that the lower sealing plate 23 closes the bottom of the storage groove 701, thereby storing and protecting the touch-pressure pen 14. By setting the lubricating oil The bottle 29 makes it possible for the stylus 14 to be stored in the storage groove 701, and the stylus 14 will keep aligned with the docking sleeve 37. At this time, the touch electric push rod 13 drives the stylus 14 to move and dock with the docking sleeve 37, thereby driving the control slide 33 to slide in the fixed sliding ring 32, so that the sealing disk 35 is separated from the sealing ring 34, thereby connecting the control tube 31. At this time, the lubricating oil inside the lubricating oil bottle 29 will flow into the threaded hole of the traveling slider 6 through the lubricating oil pipe 30 and the control pipe 31, and as the traveling slider 6 and the traveling screw rod 3 are engaged and driven, the traveling slider 6 and the traveling screw rod 3 are automatically lubricated and maintained, thereby extending the service life of the traveling screw rod 3. By setting the folding dustproof cloth 38, the folding dustproof cloth 38 on both sides will As the traveling slider 6 moves within the horizontal slide rail 2, it extends or folds, so that the traveling screw 3 within the horizontal slide rail 2 is always within the coverage of the folded dustproof cloth 38, so that the folded dustproof cloth 38 protects the traveling screw 3 and prevents dust. At the same time, the limiting guide rails 39 on the upper and lower sides can limit the folded dustproof cloth 38 to prevent it from bending forward and backward. By providing a cleaning fan 40, before the detection wheel 11 rolls for detection, the cleaning fan 40 will blow air to the bridge deck on both sides through the first blower pipe 41 and the second blower pipe 42 respectively, so that the remaining fine dust and debris on the bridge deck are blown away, thereby further preventing debris from affecting the detection accuracy of the device.
