Description

Technical Field

[0001] The invention belongs to the technical field of detection devices, in particular to a handheld reinforced concrete structure pier column safety detection device. Background Art

[0002] A pier is a lower load-bearing structure used to support the upper structure in civil engineering. The cross-section of a pier is mostly circular, but there are also special-shaped piers such as elliptical, square, curved, and parabolic. It is an important component in highway bridges, railway bridges, pedestrian bridges, overpasses, ramp bridges, and flyovers. As an important part of the bridge, the appearance design and quality management of the pier have a profound impact on the overall stability of the bridge. The detection technology and disease analysis of bridge piers are of great significance to ensuring and improving the construction and comprehensive application level of my country's bridge engineering projects.

[0003] Since most bridge piers are buried underwater, during the construction process, acceptance personnel are required to dive to perform verticality inspections. Due to underwater work, related inspection equipment can only be designed to be as small and convenient as possible to facilitate handheld operation by operators. However, when inspecting the verticality of bridge piers during underwater operations, it is difficult for operators to rely on fixed points as reference surfaces, so there will still be certain deviations in the actual inspection work, which needs to be improved.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The device can be carried to the bottom of the water by the inspectors, unfolded by pulling the climbing rail box, connected with the veneer soft rail and the vertical guide frame, and swept across the outer surface of the underwater pier column and slid vertically upward. The verticality of the underwater pier column can be detected by detecting whether the thin guide rod is deflected relative to the outer ring sleeve. Since the tiny deflection changes of the thin guide rod cannot be observed by the naked eye underwater, more sensitive deflection detection equipment is used instead of monitoring to ensure the accuracy of the detection work.

[0013] 2. When the detection component slips, the pressure pump pressurizes the inside of the main rod body through the notches of the inner rotating disk and the outer convex rotating wheel, thereby ensuring that the fine guide rod has enough pressure to slide out from the inside of the coarse guide tube without shrinking into the inside of the coarse guide tube, preventing the fine guide rod from slipping and fine-tuning and causing inaccurate detection.

[0014] 3. When pressurizing the inside of the thin guide rod, the air pressure will cause pressure on the inner wall of the rubber hose, thereby inflating the rubber hose so that the outer wall of the rubber hose can push the water pressure pallets on both sides. When the air tightness of the thin guide rod is normal, the pressure of the water pressure pallet can be used to adjust the pressure of the pressure pump on the thin guide rod to avoid the problem of continuous pressurization of the pressure pump causing internal explosion of the detection component.

[0015] 4. When the booster pump is working, the inner sliding cover located on the inner wall of the inner sliding cylinder slides to the right under the action of pressure, and then drives the slot sliding plates on both sides to slide through the traction spring cylinder, thereby pulling the tension cylinders on both sides, so that the tension cylinders trigger the climbing wheels inside the climbing rail box, so that it can work normally. If the pulling force is insufficient, it means that the thin guide rod is at risk of slipping, so as to stop the movement of the climbing rail box in time to prevent the problem of missing the detection of underwater piers due to the climbing distance of the climbing rail box being too long.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] Example 1, please refer to Figure 1-Figure 5The present invention provides a technical solution: a handheld reinforced concrete structure pier safety detection device, comprising an underwater pier 1, the outer surface of the underwater pier 1 is evenly sleeved with a veneer soft rail 2, the veneer soft rail 2 always fits the outer surface of the underwater pier 1, and the upper and lower ends of the inner wall of the underwater pier 1 are provided with large slots that allow insertion, the side of the veneer soft rail 2 is fixedly connected to a limited position strap 3, a detection component 5 is arranged at the bottom of the inner wall of the left veneer soft rail 2, and a vertical guide frame 4 is arranged at the end of the detection component 5 away from the veneer soft rail 2, the veneer soft rail 2, the limited position strap 3 and the vertical guide frame 4 are all pre-laid on the outside of the underwater pier 1, and are used to prevent the underwater pier 1 from collapsing, so as to play a limiting role;

[0026] The detection component 5 includes a clamping component 51, a coarse guide cylinder 53 is arranged on the right side of the clamping component 51, a deflection detection device 6 is arranged on the right end of the outer surface of the coarse guide cylinder 53, a fine guide rod 7 is arranged on the right end of the inner wall of the coarse guide cylinder 53, a climbing rail box 52 is arranged on the right end of the fine guide rod 7, and a convection device 8 is arranged inside the climbing rail box 52, and the climbing rail box 52 can be inserted into the bottom slot of the veneer soft rail 2, and then slide upward along the slide groove of the veneer soft rail 2 through the climbing wheel on the right side, and finally drawn out from the top slot of the veneer soft rail 2;

[0027] The deflection detection device 6 includes an outer ring sleeve 61, and an inner slider 62 is evenly arranged on the side of the inner wall of the outer ring sleeve 61 close to the thin guide rod 7. The inner slider 62 is rotatably connected to a clamping ball 64 through the inner wall of the rotating groove, and the outer surface of the inner slider 62 is fixedly connected to a side pressure plate 63 through a spring belt on the side away from the clamping ball 64. The left side of the outer surface of the climbing rail box 52 is evenly arranged with an outer plug rod, and the right side of the outer surface of the outer ring sleeve 61 is evenly arranged with a docking sleeve 65, which can push the climbing rail box 52 to the left and shrink the thin guide rod 7 into the inside of the coarse guide cylinder 53. At this time, the outer plug rod is connected to the docking sleeve 65, which is convenient for the user to carry the detection component 5 for diving.

[0028] The thin guide rod 7 includes a main rod body 71, the left end of which is fixedly connected to a piston disk 72, the right end of which is fixedly connected to an inserted slide cylinder 73, a rubber hose 74 is fixedly connected to the axis of the inner wall of the main rod body 71, and water pressure clamps 75 are symmetrically arranged on the front and rear sides of the outer surface of the rubber hose 74.

[0029] The outer surface of the piston disk 72 is slidably connected to the inner wall of the rough guide cylinder 53, the left side of the inner wall of the outer ring sleeve 61 is fixedly connected to the right end of the rough guide cylinder 53, the outer surface of the clamping ball 64 is pressed against the outer surface of the main rod body 71, the number of the inner sliders 62 is six, and the outer surface of the inner slider 62 is slidably connected to the inner wall of the outer ring sleeve 61 through the guide slide groove, and the outer surface of the side pressure plate 63 is fixedly connected to the inner wall of the outer ring sleeve 61. The left and right ends of the rubber hose 74 are fixedly connected to the middle of the inner wall of the main rod body 71, one side of the outer surface of the water pressure card 75 is fixedly connected to the outer surface of the rubber hose 74, the other side of the outer surface of the water pressure card 75 is fixedly connected to the inside of the main rod body 71, and the outer surface of the inner slide 73 is fixedly connected to the inner wall of the climbing device.

[0030] After the tester dives into the water holding the detection component 5, he pulls out the thin guide rod 7 of the detection component 5 from the inside of the thick guide tube 53, selects a vertical guide frame 4, and then inserts the climbing rail box 52 into the slot at the bottom of the veneer soft rail 2, and clamps the clamping component 51 with the vertical guide frame 4 at the corresponding position. After adjustment, ensure that the detection component 5 and the veneer soft rail 2 remain in a vertical state.

[0031] The climbing rail box 52 climbs up along the veneer soft rail 2 through the rollers on the inner wall, and then drives one side of the clamping component 51 to climb up synchronously. After climbing a certain distance, the climbing rail box 52 stops moving. Since the vertical guide frame 4 must remain vertical to the bottom of the water, and one side of the climbing rail box 52 always fits the underwater pier 1, if the thin guide rod 7 and the thick guide tube 53 are deflected, it means that the underwater pier 1 is not parallel to the vertical guide frame 4 at this time, that is, the underwater pier 1 is tilted.

[0032] When the climbing rail box 52 drives the main rod body 71 to bend relative to the coarse guide tube 53 through the inner slide tube 73, the piston disk 72 will be compressed accordingly. At this time, the main rod body 71 will squeeze the clamping ball 64 on the deflected side, thereby pushing the inner slide block 62 to squeeze the corresponding side pressure plate 63. At this time, the side pressure plate 63 inside the outer ring sleeve 61 will be unevenly stressed, and the bending and deviation of the underwater pier 1 will be detected.

[0033] When performing the fixing work, the waterproof shell 511 pushes the clamping turn plate 513 through the side push spring plates 512 on both sides, so that the clamping turn plate 513 fits the outer surface of the vertical guide frame 4, and the vertical guide frame 4 can slide relative to the outer surface of the vertical guide frame 4. When the detection component 5 slips, the pressure pump 514 pressurizes the interior of the main rod body 71 through the cutouts of the inner rotating disk 517 and the outer convex rotating wheel 516, thereby ensuring that the thin guide rod 7 has enough pressure to slide out from the inside of the coarse guide cylinder 53 without shrinking into the inside of the coarse guide cylinder 53.

[0034] When the inside of the thin guide rod 7 is pressurized, the air pressure will cause pressure on the inner wall of the rubber hose 74, thereby inflating the rubber hose 74 so that the outer wall of the rubber hose 74 can push the water pressure clamps 75 on both sides. When the air tightness of the thin guide rod 7 is normal, the pressure exerted by the pressure pump 514 on the thin guide rod 7 can be adjusted by the pressure on the water pressure clamp 75, thereby avoiding the problem of continuous pressurization of the pressure pump 514 causing the internal explosion of the detection component 5.

[0035] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of the first embodiment, the clamping component 51 comprises a waterproof shell 511, a clamping rotating plate 513 is symmetrically arranged on the left side of the inner wall of the waterproof shell 511, a side thrust spring plate 512 is fixedly connected to the outer surface of the waterproof shell 511 on the outer surface of the clamping rotating plate 513, and the side of the side thrust spring plate 512 away from the clamping rotating plate 513 is fixedly connected to the outer surface of the waterproof shell 511. A pressure pump 514 is fixedly connected to the left side of the inner wall of the waterproof shell 511, and the right side of the output shaft of the pressure pump 514 is rotatably connected to the inner rotating disk 517, and the upper and lower sides of the outer surface of the inner rotating disk 517 are symmetrically arranged with outer convex wheels 516, and the axis of the outer convex wheel 516 is fixedly connected to the torsion motor 515, and the axis of the outer surface of the outer convex wheel 516 is rotatably connected to the docking disk 518 on the right side of the outer surface, and four through-cut grooves are opened on the docking disk 518 and extend to the outside of the inner rotating disk 517. The outer surface of the torsion motor 515 is fixedly connected to the inner wall of the waterproof shell 511, the outer surface of the convex rotating wheel 516 is rotatably connected to the side of the inner rotating disk 517, the left end of the main rod body 71 is fixedly connected to the right side of the outer surface of the waterproof shell 511, and the outer surface of the docking disk 518 is sleeved on the left side of the inner wall of the main rod body 71.

[0036] The convection device 8 includes an inner sliding cover 81, a traction spring cylinder 82 is fixedly connected at the axis of the outer surface of the inner sliding cover 81, a slot slide 83 is symmetrically arranged at one end of the traction spring cylinder 82 away from the inner sliding cover 81, and a tension cylinder 84 is slidably connected to the end of the slot slide 83 away from the traction spring cylinder 82 through a pull rod. The outer surface of the inserted slide 73 is fixedly connected to the axis of the left side of the inner wall of the climbing rail box 52, the outer surface of the inner sliding cover 81 is slidably connected to the inner wall of the inserted slide 73, the outer surface of the slot slide 83 is slidably connected to the inner cavity of the inserted slide 73 through a guide slide groove, the outer surface of the tension cylinder 84 is fixedly connected to the inner wall of the climbing rail box 52, and the right side of the outer surface of the climbing rail box 52 is slidably connected to the inner wall of the veneer soft rail 2.

[0037] When air leakage occurs between the coarse guide tube 53 and the thin guide rod 7, the pressure on the water pressure clamp 75 will decrease. At this time, the pressure pump 514 is required to supplement the air pressure to ensure that the thin guide rod 7 will not shrink into the inside of the coarse guide tube 53. After the pressurization is completed, the torsion motor 515 will rotate the inner rotating disk 517 through the outer convex rotating wheel 516, so that the ventilation groove of the inner rotating disk 517 is staggered with the ventilation groove of the docking disk 518, thereby preventing external water from entering the waterproof shell 511.

[0038] When the pressure pump 514 is working, the inner sliding cover 81 located on the inner wall of the inserted sliding cylinder 73 slides to the right under the action of pressure, and then drives the slot slides 83 on both sides to slide through the traction spring cylinder 82, thereby pulling the tension cylinder 84 on both sides, so that the tension cylinder 84 triggers the climbing wheel inside the climbing rail box 52, so that it can work normally. If the pulling force is insufficient, it means that the thin guide rod 7 is at risk of slipping, so the movement of the climbing rail box 52 is stopped in time.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
