Description

Technical Field

[0001] The invention relates to the technical field of precast concrete detection, and in particular to a detection device for special-shaped parts of assembled concrete. Background Art

[0002] The main components of partially assembled concrete buildings are generally prefabricated components, which are connected on site through cast-in-place concrete to form an assembled integral structure building. The main structure of the concrete structure relies on nodes and joints to connect the structure into a whole and meet the bearing capacity, stability, rigidity and ductility requirements during the use and construction stages.

[0003] The pier is used to bear the lower load-bearing objects of the upper structure. The cross-section of the pier is mostly circular, and there are also elliptical, square, curved, parabolic and other special-shaped piers. It is an important component of the bridge. The prefabricated piers required in the prefabricated bridge need to be prefabricated in the factory in advance. After the production, the piers need to be checked for size and castable data. In order to ensure the integrity and stress of the structure, the prefabricated piers need to be laid down and loaded during transportation from the factory to the construction site. In this process, the stress of the piers is gradually converted from a vertical state to an eccentric state. The test needs to be strictly carried out according to the laying process to avoid damage to the prefabricated piers caused by the laying process. In addition, for the quality of the prefabricated piers shipped out of the factory, the prefabricated piers need to be inspected before delivery. At present, the damage is mainly judged by the appearance of the workers. It is impossible to judge whether some internal structures are damaged, such as whether the grouting holes and the built-in steel bars are rusted due to storage.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example, see Figure 1-Figure 7 , a detection device for prefabricated concrete irregular parts, comprising a quality inspection platform 1 and a data display device arranged on the quality inspection platform 1, the quality inspection platform 1 is provided with two groups of support units for supporting prefabricated piers, and the support units are provided with a sliding detection component for detecting the integrity of the prefabricated piers;

[0036] It is worth noting that the data display device is an intelligent display device, which can integrate the detected data through a computer and finally present them on a display screen for display, thereby assisting in the rapid identification of the display of various detection data of precast concrete piers.

[0037] The supporting unit has two groups of two oppositely arranged bearing bases 2, and the two oppositely arranged bearing bases 2 are connected to each other through an intelligent electric push rod 3 to achieve relative movement; a connecting slider 33 is provided at the end of the intelligent electric push rod 3, and a vertical slide groove is provided on the side wall of the bearing base 2 for the connecting slider 33 to slide, which can achieve height compensation between the intelligent electric push rod 3 and the bearing base 2.

[0038] It is worth noting that the two groups of bearing bases 2 are respectively located on both sides of the prefabricated pier column and cooperate with each other during use. When one bearing base 2 in one group plays a supporting role, the other bearing base 2 of this group can be moved by the telescopic force generated by the intelligent electric push rod 3, so that the cracks on the surface of the prefabricated pier column can be detected by the sliding detection component arranged thereon, mainly for the cracks in the bottom part that cannot be observed. The structure is not arranged above in order to facilitate the hoisting of the prefabricated pier column and the prefabricated pier column above, so that the naked eye can directly observe whether the cracks are generated;

[0039] In addition, this plan is aimed at secondary inspection, that is, after the routine inspection of the prefabricated piers, the surface damage that is prone to occur during the laying process is inspected.

[0040] A conversion lifting component for controlling the supporting effect is arranged in the bearing base 2; the conversion lifting component comprises a conversion chamber 15 provided in the bearing base 2, a triangular pressure seat 16 is arranged at the center of the inner wall of the conversion chamber 15, and inclined support blocks 17 are arranged on both sides of the triangular pressure seat 16, and the two inclined support blocks 17 extend downward and are slidably connected to a lifting chassis 18;

[0041] The two inclined support blocks 17 are connected to the same horizontal driving screw 19 through a screw nut, and a conversion lifting motor 20 is arranged on one side of the lifting chassis 18, and the output end of the conversion lifting motor 20 is connected to the horizontal driving screw 19;

[0042] It is worth noting that the horizontal driving screw 19 is provided with two sets of thread layers arranged in opposite spiral directions, which, when rotating, will cause the inclined support block 17 to move in opposite or opposite directions;

[0043] The bearing base 2 is provided with a receiving opening 21, and the telescopic adapting pressure plate 4 is located in the receiving opening 21, and the two sides thereof are fixedly connected with inclined side plates 22 penetrating into the conversion chamber 15, and the inclined support block 17 is arranged at an angle to the side opposite to the inclined side plate 22;

[0044] It is worth noting that the inclined support block 17 is adapted to the opposite surface of the inclined side plate 22. When the inclined support block 17 moves to both sides, it will exert pressure on the inclined side plate 22, thereby driving the telescopic adapter pressure plate 4 in the storage port 21 to move upward for integrity detection.

[0045] The effect of using the conversion lifting component is that by driving the conversion lifting motor 20, the horizontal driving screw 19 is driven to rotate, which will cause the inclined support block 17 to move, so that the triangular pressure seat 16 in contact with it moves upward under the action of the inclined resistance force, and then lifts the bearing base 2, thereby meeting the lifting and supporting effect of the prefabricated pier.

[0046] The sliding detection assembly includes a telescopic adaptable pressure plate 4 arranged on the bearing base 2, and a plurality of telescopic detection members are arranged on the inner wall of the telescopic adaptable pressure plate 4. The telescopic detection members are connected to a liquid level observation column 5 fixed on one side of the bearing base 2 through a pipeline, and a pressure sensor is arranged in the liquid level observation column 5 for detecting the liquid level rise and fall height;

[0047] It is worth noting that the setting of the pressure sensor can intuitively obtain the pressure inside the pressure chamber 23, so as to judge the integrity of the surface of the prefabricated pier;

[0048] Furthermore, the telescopic detection component includes a pressure chamber 23 opened in the telescopic adapter pressure plate 4, and the telescopic adapter pressure plate 4 is densely provided with pressure detection tubes 24 connected to the pressure chamber 23. A pressure piston 25 is provided in the pressure detection tube 24. The pressure piston 25 is connected to a resistance member 26 extending outward and abutting against the prefabricated pier column. An observation float is provided inside the liquid level observation column 5. The setting of the observation float can facilitate the observation of the height change of the liquid level. The liquid level observation column 5 is connected to the pressure chamber 23 through a pipeline.

[0049] A further advantage of using a telescopic detection piece is that when the telescopic adapter pressure plate 4 moves upward, the resistance piece 26 at the end of the telescopic detection piece will resist the surface of the prefabricated pier. Under the action of the resistance force, the pressure in the pressure chamber 23 will increase. When the surface of the prefabricated pier is damaged or cracked, the pressure piston 25 will drive the resistance piece 26 to move outward under the pressure of the pressure chamber 23. At this time, the pressure piston 25 is displaced, which will cause the pressure in the pressure chamber 23 to decrease. By observing the liquid level column 5 and the pressure sensor, it can be concluded that there is a defect in the integrity of the prefabricated pier.

[0050] On both sides of the support unit, there are respectively provided an injection flow detection component for detecting the quality of the grouting holes of the prefabricated pier column and a resistance detection component for inspecting the quality of the steel bars of the prefabricated pier column;

[0051] The liquid injection flow detection component includes a high-pressure liquid injection device 7 arranged on one side of the quality inspection platform 1, a side of the bearing base 2 is connected to a return-shaped pressure cover 8 through a connecting plate 6, a high-pressure water delivery ring 9 connected to the high-pressure liquid injection device 7 is arranged in the return-shaped pressure cover 8, and the inner wall of the high-pressure water delivery ring 9 is connected to a liquid injection head 10 through a magnetic push component;

[0052] Furthermore, the magnetic push assembly includes a plurality of connection ports opened on the inner wall of the high-pressure water supply ring 9, the injection head 10 is located in the connection port and can achieve relative sliding, the inner wall of the high-pressure water supply ring 9 is provided with a control electromagnetic plate 27, and the outer wall of the injection head 10 is fixedly connected with a magnetic repulsion ring 28 that repel the control electromagnetic plate 27 by magnetic force, and the magnetic repulsion ring 28 is connected to the inner wall of the high-pressure water supply ring 9 through a reset spring.

[0053] The circular pressure cover 8 is connected to the detection panel 12 through an adjustable support rod 11. The detection panel 12 is provided with a liquid outlet detection component, which includes a plurality of docking detection tubes 29 arranged on the detection panel 12. A hydraulic detection piston 30 is arranged inside the docking detection tube 29, and a pushing observation column 31 is arranged at the end of the hydraulic detection piston 30.

[0054] During the inspection, the end of the docking inspection tube 29 is inserted into the grouting hole on the prefabricated pier column. A sealing rubber is provided at the docking position between the docking inspection tube 29 and the grouting hole to ensure that the liquid injected into the prefabricated pier column can be squeezed into the docking inspection tube 29.

[0055] The advantage of adopting the above structure is that, under the same pressure, when the grouting hole is not blocked or the size meets the size standard, the pressure of the liquid flowing out is certain, so the speed of movement of the hydraulic detection piston 30 can be used to determine whether the grouting hole meets the standard.

[0056] The resistive detection assembly includes a resistance test panel 13, which is connected to a supporting base 2 near one side. A plurality of wiring sleeves 14 are provided on the resistance test panel 13. A current sensing data display device for detecting resistance changes is provided on the resistance test panel 13. Two elastic wiring paddles 32 are provided in the wiring sleeve 14, which are respectively connected to positive and negative wires. The elastic wiring paddles 32 can ensure contact with the steel bars, and the positive and negative wires are electrically connected to the current sensing data display device.

[0057] During the secondary inspection, since the prefabricated piers are placed for a long time after preparation, the cast steel bars inside them may rust. The resistance change after the steel bars are energized can be used to determine whether the steel bars are rusted based on the current intensity. The reason is that the rusting process of the steel bars is an oxidation process, and the resistance of the produced oxides is significantly increased compared to the metal. Therefore, the design threshold of the current can be used to determine whether the steel bars are rusted and whether they meet the connection standards of prefabricated buildings.

[0058] The present invention performs the final quality inspection before delivery after the prefabricated pier is laid down for transportation. The laid down prefabricated pier is placed on the support unit by means of a hoisting device. The quality inspector observes the surface of the prefabricated pier. For the bottom position which is inconvenient to observe, the sliding inspection component is used for inspection.

[0059] Through the two groups of bearing bases 2 arranged relatively to each other, when conducting the inspection, the bearing base 2 on one side is used as the supporting effect, and the support of the bearing base 2 on the other side is released, specifically, the horizontal driving screw 19 connected to the conversion lifting motor 20 is controlled to rotate, so that the inclined support block 17 inside it moves away from both sides. In the process of moving away, the supporting force of the triangular pressure seat 16 will disappear, and the telescopic adaptor pressure plate 4 connected to the inclined side plate 22 in contact with it will be pushed to move upward, so that the telescopic adaptor pressure plate 4 in the storage port 21 moves outward, and the resistance piece 26 arranged on the telescopic adaptor pressure plate 4 will contact the surface of the prefabricated pier column. At this time, the bearing base 2 on the other side is controlled to move by the intelligent electric push rod 3. During the movement, the resistance piece 26 will realize the detection of the surface integrity of the prefabricated pier column;

[0060] During the storage and laying down of the prefabricated piers, the pouring holes may be blocked or the internal structure may be damaged when the piers are laid down, which may affect the subsequent pouring. The detection can be carried out by moving the supporting base 2 to drive the return-shaped pressure cover 8 to move to the position of the pouring hole on the corresponding side wall, and the docking detection tube 29 on the detection panel 12 is moved to the position of the corresponding bottom pouring hole, and is controlled to block the two ends of the pouring hole respectively. At this time, high-pressure liquid is injected into the pouring hole through the high-pressure liquid injection device 7. At this time, by observing the speed of the push observation column 31, it is judged whether the pouring hole has insufficient flow caused by blockage, so as to realize the detection of the permeability of the pouring hole.

[0061] When testing the steel bars during the placement of prefabricated piers, the movement of the bearing base 2 drives the resistance test panel 13 to move, so that the wiring sleeves 14 arranged on the resistance test panel 13 contact the leaked parts of the steel bars one by one. At this time, the elastic wiring paddle 32 is powered, and conducts electricity through the steel bars. The resistance of the steel bars is determined by the ammeter to determine whether the steel bars are oxidized and rusted, thereby ensuring the quality of the prefabricated building.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
