Description

Technical Field

[0001] The present invention relates to the technical field of concrete pressure detection devices, and particularly relates to a concrete pressure detection device for road bridge tunnel linings. Background Art

[0002] The lining trolley for road bridges and tunnels is a non-standard product specifically designed and manufactured for concrete linings of different cross-sectional sizes such as tunnels and culverts. Since whether the concrete is filled completely is related to the quality of the entire lining, it is necessary to detect the concrete pressure of the lining. However, the existing pressure detection devices are generally force collectors. When detecting the concrete pressure of the lining, the force collector is generally arranged between two clamping sleeves in a limit frame. The outside of the force collector will push the clamping sleeves to squeeze the telescopic rod and the supporting spring, and the telescopic rod and the supporting spring are compressed. At this time, through the acting force of the supporting spring, the force collector is clamped and fixed between the two clamping sleeves. However, the fixing effect of clamping the force collector by the acting force of the spring is poor. When the force collector is subjected to a certain external force, it will shift, thus affecting the detection accuracy of the lining concrete pressure, affecting the accuracy of the pressure detection, and further affecting the judgment accuracy of whether the top of the lining is filled completely, and easily causing the phenomenon of concrete cavities at the top of the lining. Based on this, the present invention provides a concrete pressure detection device for road bridge tunnel linings to solve the problems raised in the above background art. Summary of the Invention

By setting up a clamping mechanism, the inspection table moves upward to be flush with the top of the trolley panel, so as to make the inspection table contact the tunnel lining concrete. Since the inspection table abuts against the force collector through the first moving plate, the pressure during the pouring of the tunnel lining concrete can be transmitted to the force collector through the inspection table, which is convenient for subsequent detection of the pressure of the tunnel lining concrete. At the same time, the clamping plates move towards each other to clamp and fix the force collector placed on the lifting box, preventing the poor fixing effect of clamping the force collector by the acting force of the existing spring.

One end of the second rotating shaft 26 rotatably penetrates the inner wall of the installation box 1 and is fixedly sleeved with a worm gear 25. A worm 24 is meshed and connected to one side of the worm gear 25. First mounting plates 23 are installed on the installation box 1 outside both ends of the worm 24. A first rotating shaft 22 penetrates through the worm 24. The two ends of the first rotating shaft 22 are respectively rotatably connected to the first mounting plates 23; the first mounting plate 23 is used to install the first rotating shaft 22, and one end of the first rotating shaft 22 rotatably penetrates the first mounting plate 23 and is connected to the driving member 21; the driving member 21 is a rotating handle; Two first gears 27 are respectively and fixedly sleeved on a second rotating shaft 26 in an installation box 1. The second rotating shaft 26 is located at an eccentric position of the first gear 27. A second gear 28 is meshed and connected above the first gear 27. A same third rotating shaft 29 penetrates through the eccentric positions of the two second gears 28. Inner walls of the installation box 1 outside two ends of the third rotating shaft 29 are both provided with second moving plates 210 in a sliding manner. Two ends of the third rotating shaft 29 are respectively and rotatably connected to inner sides of bottoms of the second moving plates 210. The tops of the two second moving plates 210 are connected to a same lifting box 2. Two second telescopic rods 211 are installed on both the front and rear sides of the second rotating shaft 26. First ends of the two second telescopic rods 211 at the same end are connected to the bottom end of a same second moving plate 210. Second ends of the two second telescopic rods 211 at the same end are connected to the bottom wall of the installation box 1. Second elastic members 212 are installed on the second telescopic rods 211. A first end of the second elastic member 212 is connected to the bottom end of the second moving plate 210. A second end of the second elastic member 212 is connected to the bottom wall of the installation box 1. The second telescopic rods 211 and the second elastic members 212 cooperate to ensure the stable movement of the second moving plates 210. Specifically, the first elastic member 107 and the second elastic member 212 are both compression springs. The third rotating shaft 29 drives a clamping mechanism to work through rotation. One of the second moving plates 210 drives an opening and closing mechanism to work through movement. Preferably, a driving member 21 drives a first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 drives a worm 24 to rotate. The rotation of the worm 24 drives a worm gear 25 to rotate. The rotation of the worm gear 25 drives the second rotating shaft 26 to rotate. The rotation of the second rotating shaft 26 drives the first gear 27 to rotate.

The rotation and upward movement of the second gear 28 drive the rotation and upward movement of the third rotating shaft 29. The rotation and upward movement of the third rotating shaft 29 drive the upward movement of the second moving plate 210. At this time, both the second telescopic rod 211 and the second elastic member 212 are stretched. The upward movement of the second moving plate 210 drives the upward movement of the lifting box 2. The upward movement of the lifting box 2 drives the upward movement of the force collector 102. The upward movement of the force collector 102 abuts against the first moving plate 105 and drives the first moving plate 105 to move upward. At this time, both the first telescopic rod 106 and the first elastic member 107 are compressed. The upward movement of the first moving plate 105 drives the upward movement of the detection table 104. The detection table 104 moves upward to be flush with the top of the trolley panel 101, thereby realizing the contact between the detection table 104 and the tunnel lining concrete. Since the detection table 104 abuts against the force collector 102 through the first moving plate 105, the pressure during the pouring of the tunnel lining concrete can be transmitted to the force collector 102 through the detection table 104, which is convenient for subsequent detection of the pressure of the tunnel lining concrete; Preferably, when the pressure detection is completed, the driving member 21 is driven in the reverse direction to make the force collector 102 move downward.

The second end of the rotating rod 46 is vertically connected to the first end of a second sliding column 47. The second end of the second sliding column 47 is slidably connected and arranged in the third through groove. Preferably, when the second moving plate 210 moves upward, it drives the toothed plate 41 to move upward. The upward movement of the toothed plate 41 drives the third gear 42 to rotate. The rotation of the third gear 42 drives the fourth rotating shaft 45 to rotate. The rotation of the fourth rotating shaft 45 drives the rotating rod 46 to rotate.

[0020] The usage method of the present invention: When it is necessary to detect the pressure of the tunnel lining concrete, multiple pressure detection devices can be installed on the top panel 101 of the trolley. The staff places the force collector 102 between the two clamping plates 3 on the lifting box 2, and the staff drives the driving member 21. The driving member 21 drives the first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 drives the worm 24 to rotate. The rotation of the worm 24 drives the worm gear 25 to rotate. The rotation of the worm gear 25 drives the second rotating shaft 26 to rotate. The rotation of the second rotating shaft 26 drives the first gear 27 to rotate. Since the second rotating shaft 26 is located at an eccentric position of the first gear 27, the first gear 27 is meshed and connected with a second gear 28 above it, and the same third rotating shaft 29 penetrates through the eccentric positions of the two second gears 28. So that the rotation of the first gear 27 drives the second gear 28 to rotate and move upward. The rotation and upward movement of the second gear 28 drive the third rotating shaft 29 to rotate and move upward. The rotation and upward movement of the third rotating shaft 29 drive the second moving plate 210 to move upward. At this time, both the second telescopic rod 211 and the second elastic member 212 are stretched. The upward movement of the second moving plate 210 drives the lifting box 2 to move upward. The upward movement of the lifting box 2 drives the force collector 102 to move upward. The upward movement of the force collector 102 abuts against the first moving plate 105 and drives the first moving plate 105 to move upward. At this time, both the first telescopic rod 106 and the first elastic member 107 are compressed. The upward movement of the first moving plate 105 drives the detection table 104 to move upward. The detection table 104 moves upward until it is flush with the top of the trolley panel 101, thereby realizing that the detection table 104 contacts the tunnel lining concrete. Since the detection table 104 abuts against the force collector 102 through the first moving plate 105, the pressure during the pouring of the tunnel lining concrete can be transmitted to the force collector 102 through the detection table 104, which is convenient for subsequent detection of the pressure of the tunnel lining concrete. Meanwhile, the rotation of the third rotating shaft 29 drives the rotation of the first bevel gear 31. The rotation of the first bevel gear 31 drives the rotation of the second bevel gear 32. The rotation of the second bevel gear 32 drives the rotation of the threaded rod 33. The rotation of the threaded rod 33 drives the third moving plate 35 to move upward; Since the front side of the third moving plate 35 is provided with a V-shaped sliding groove, the two first sliding columns 36 are respectively slidably connected and arranged in the two inclined grooves of the V-shaped sliding groove; The upward movement of the third moving plate 35 drives the first sliding columns 36 to move towards each other. The first sliding columns 36 moving towards each other drive the first moving rod 37 to move towards each other. The first moving rod 37 moving towards each other drives the second moving rod 38 to move towards each other. The second moving rod 38 moving towards each other drives the clamping plates 3 to move towards each other. The clamping plates 3 moving towards each other are used to clamp and fix the force collector 102 placed on the lifting box 2, preventing the poor fixing effect of clamping the force collector 102 by the acting force of the spring in the prior art. When the force collector 102 is affected by a certain external force, it will shift, thus affecting the detection accuracy of the lining concrete pressure and the accuracy of the pressure detection. Furthermore, the judgment accuracy of whether the top of the lining is filled is affected, and it is easy to cause the phenomenon of concrete cavities at the top of the lining, improving the clamping and fixing effect; Meanwhile, the upward movement of the second moving plate 210 drives the toothed plate 41 to move upward. The upward movement of the toothed plate 41 drives the third gear 42 to rotate. The rotation of the third gear 42 drives the fourth rotating shaft 45 to rotate. The rotation of the fourth rotating shaft 45 drives the rotating rod 46 to rotate. The rotation of the rotating rod 46 drives the second sliding column 47 to rotate. The rotation of the second sliding column 47 drives the first shift lever 48 to move leftward. The first shift lever 48 moving leftward drives the third sliding column 49 to move leftward. The third sliding column 49 moving leftward drives the second shift lever 410 to rotate around the fifth rotating shaft 411. The second shift lever 410 rotating around the fifth rotating shaft 411 drives the fifth rotating shaft 411 to rotate. The rotation of the fifth rotating shaft 411 drives the protective door 4 to rotate, and the protective door 4 rotates and then closes, facilitating the protection of the force collector 102, ensuring the accuracy of the lining concrete pressure detection result, and thus improving the quality of the entire lining; Then the lining concrete can be poured. Meanwhile, the pressure processor 103 is started. When the concrete is poured to the top, the concrete pressure is transmitted to the force collector 102 through the detection table 104. The force collector 102 deforms due to an external force acting on it and emits a signal. The signal is displayed through the pressure processor 103, and the display result is converted into the magnitude of the pressure value through the contact area of the detection table 104. Whether the top of the lining is filled can be judged according to the magnitude of the pressure value; When the pressure detection is completed, drive the driving member 21 in the reverse direction to move the force collector 102 downward. At this time, the first telescopic rod 106 and the first elastic member 107 are reset and stretched, and both the first moving plate 105 and the detection table 104 move downward. Continuing to move, the force collector 102 is separated from the first moving plate 105; At the same time, the clamping plates 3 move away from each other to release the clamping and fixing of the force collector 102 placed on the lifting box 2; At the same time, rotate the protective door 4 to open it, facilitating the disassembly, maintenance and replacement of the force collector 102 by the staff.

[0021] In the present invention, by setting the lifting mechanism, the detection table is moved upward to be flush with the top of the trolley panel, so as to realize the contact between the detection table and the tunnel lining concrete. Since the detection table abuts against the force collector through the first moving plate, the pressure during the pouring of the tunnel lining concrete can be transmitted to the force collector through the detection table, which is convenient for subsequent detection of the pressure of the tunnel lining concrete; by setting the clamping mechanism, the detection table is moved upward to be flush with the top of the trolley panel, so as to realize the contact between the detection table and the tunnel lining concrete. Since the detection table abuts against the force collector through the first moving plate, the pressure during the pouring of the tunnel lining concrete can be transmitted to the force collector through the detection table, which is convenient for subsequent detection of the pressure of the tunnel lining concrete. At the same time, the clamping plates move towards each other to clamp and fix the force collector placed on the lifting box, preventing the poor fixing effect of clamping the force collector by the acting force of the existing spring. When the force collector is affected by a certain external force, it will shift, thus affecting the detection accuracy of the lining concrete pressure, affecting the accuracy of the pressure detection, and further affecting the judgment accuracy of whether the top of the lining is fully poured, easily causing the phenomenon of concrete cavities at the top of the lining. The clamping and fixing effect is improved; by setting the opening and closing mechanism, when the force collector is separated from the first moving plate, the clamping plates move away from each other to release the clamping and fixing of the force collector placed on the lifting box, and at the same time, the protective door rotates and opens, facilitating the disassembly, maintenance and replacement of the force collector by the staff; the structure of the present invention is simple and reliable, has a good effect on the concrete pressure detection, is convenient to control, and is suitable for popularization.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
