Description

Technical Field

[0001] The invention relates to the field of building detection equipment, in particular to a device for detecting the anti-cracking bearing capacity of a precast concrete cover plate. Background Art

[0002] Prefabricated construction refers to a building that transfers a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on-site through reliable connection methods, which greatly reduces the amount of work required compared to the original cast-in-place work.

[0003] In the existing precast concrete cover slab anti-crack bearing capacity detection device, during use, some cover slabs are not easy to detect when cracks appear during the detection process, which can easily lead to errors in the detection results, affect subsequent use, and cause inconvenience to the staff. Therefore, in view of the above situation, it is urgent to develop a precast concrete cover slab anti-crack bearing capacity detection device to overcome the shortcomings in current practical applications. Summary of the invention

[0004] The purpose of the present invention is to provide a device for detecting the anti-cracking bearing capacity of a precast concrete cover plate to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The precast concrete cover plate crack resistance bearing capacity detection device comprises a support platform and also comprises:

[0007] A detection power box, the detection power box is connected to the support platform through a cylindrical rod;

[0008] A thrust assembly, the thrust assembly being located in the detection power box; and

[0009] A detection mechanism, the detection mechanism is connected to the support platform and the cylindrical rod respectively, and is installed in coordination with the thrust assembly;

[0010] Among them, the detection mechanism includes an elastic pad, an observation tube, a protruding plate, an observation component and a pressurizing component. The protruding plate is connected to the cylindrical rod, and an observation tube is also installed on the protruding plate. The elastic pad is respectively connected to the detection power box and the protruding plate, and the observation component is respectively connected to the detection power box and the observation tube. The pressurizing component is located in the detection power box and is installed in conjunction with the observation tube.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When it is necessary to inspect the precast concrete cover plate, first, through the support platform that is set up, wherein the bottom of the support platform is provided with rollers, the overall inspection device can be moved to the designated position to facilitate the staff to place the cover plate, and then, through the protruding plate that is set up, the cover plate that needs to be inspected can be inserted between the inspection power box and the protruding plate, wherein the protruding plate is located directly below the inspection power box, and through the elastic pad that is set up, wherein the elastic pads are respectively located on the inspection power box and the protruding plate, and in conjunction with the external clamping structure, such as in the form of bolt clamping, the cover plate can be firmly placed between the inspection power box and the protruding plate, and the cover plate is in close contact with the elastic pad. On the one hand, the friction between the cover plate and the elastic pad can be increased to avoid shaking during the inspection process, and on the other hand, the sealing between the cover plate and the elastic pad can be improved, providing conditions for subsequent observation work. When the precast cover plate is placed, the thrust assembly and the pressure assembly can be started to work, and at the same time, the observation assembly can also be put into operation. During the process of the thrust assembly gradually moving downward, it can contact the cover plate at the bottom and generate an extrusion force on the cover plate.

On the other hand, when cracks appear, high-pressure wind blows through the cracks into the observation tube, where the observation tube is located directly below the cover plate, and powder or fine particles are provided in the observation tube. Under the action of wind, the powder can flow. At this time, the observation assembly can be set up to facilitate the staff to understand the detection situation in a timely and rapid manner, so that the thrust assembly can be accurately shut down, so that when imperceptible cracks appear during the detection process, the staff can understand the situation in a timely manner, thereby improving the detection results and ensuring the accuracy of the detection results. It provides convenience for the staff and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] See also Figure 1-6 The anti-cracking bearing capacity detection device of the precast concrete cover provided by the embodiment of the present invention comprises a support platform 1, and also comprises:

[0023] A detection power box 4, wherein the detection power box 4 is connected to the support platform 1 through a cylindrical rod 2;

[0024] A thrust assembly, the thrust assembly being located in the detection power box 4; and

[0025] A detection mechanism, which is connected to the support platform 1 and the cylindrical rod 2 respectively, and is installed in coordination with the thrust assembly;

[0026] Among them, the detection mechanism includes an elastic pad 7, an observation tube 9, a protruding plate 31, an observation component and a pressurizing component. The protruding plate 31 is connected to the cylindrical rod 2, and the observation tube 9 is also installed on the protruding plate 31. The elastic pad 7 is respectively connected to the detection power box 4 and the protruding plate 31, and the observation component is respectively connected to the detection power box 4 and the observation tube 9. The pressurizing component is located in the detection power box 4 and is installed in conjunction with the observation tube 9.

[0027] When it is necessary to inspect the precast concrete cover plate, first, through the support platform 1, a roller is provided at the bottom of the support platform 1, and the whole inspection device can be moved to the designated position to facilitate the staff to place the cover plate, and then, through the protruding plate 31, the cover plate to be inspected can be inserted between the inspection power box 4 and the protruding plate 31, wherein the protruding plate 31 is located directly below the inspection power box 4, and through the elastic pad 7, wherein the elastic pad 7 is respectively located on the inspection power box 4 and the protruding plate 31, and in conjunction with the external clamping structure, such as the form of bolt clamping, the cover plate can be fastened and placed between the inspection power box 4 and the protruding plate 31, and the cover plate is in close contact with the elastic pad 7. On the one hand, the friction between the cover plate and the elastic pad 7 can be increased to avoid shaking during the inspection process, and on the other hand, the sealing between the cover plate and the elastic pad 7 can be improved to provide conditions for subsequent observation work. When the precast cover plate is placed, the thrust assembly and the pressure assembly can be started to work. At the same time, The observation component is also put into operation. During the process of the thrust component gradually moving downward, it can contact the cover plate at the bottom and generate an extrusion force on the cover plate. As the pressure of the thrust component increases, when cracks appear on the cover plate, the pressurizing component can be operated in the form of exhausting air, so that the detection power box 4 can be placed in an environment slightly higher than the atmospheric pressure. On the one hand, the equipment in the detection power box 4 can be air-cooled. On the other hand, when cracks appear, high-pressure wind blows through the cracks into the observation tube 9, wherein the observation tube 9 is located directly below the cover plate, and powder or fine particles are provided in the observation tube 9. Under the action of wind force, the powder can flow. At this time, through the set observation component, it is convenient for the staff to understand the detection situation in a timely and rapid manner, so that the thrust component can be accurately shut down, so that when imperceptible cracks appear during the detection process, the staff can understand the situation in a timely manner, thereby improving the detection results and ensuring the accuracy of the detection results. It provides convenience for the staff and is worthy of promotion.

[0028] In one embodiment of the present invention, see Figure 1 and Figure 2 , the thrust assembly comprises:

[0029] A thrust piece 18, wherein the thrust piece 18 is connected to the inner wall of the detection power box 4 through a partition plate 17; and

[0030] A force bearing plate 32 connected to an output end of the thrust member 18 .

[0031] By setting up a thrust piece 18, which can be a hydraulic cylinder or other forms, the thrust piece 18 can be started to drive the force-bearing plate 32 to move downward and contact the cover plate to be tested. As the pressure of the thrust piece 18 gradually increases, the anti-crack bearing capacity of the cover plate can be tested.

[0032] In one embodiment of the present invention, see Figure 1-3 , the pressurizing component comprises:

[0033] A vent 6, the vent 6 is opened on the top of the detection power box 4;

[0034] A pressurizing member 19, wherein the pressurizing member 19 is located on the partition 17, and a nozzle 20 is fixedly mounted on the output end of the pressurizing member 19; and

[0035] The exhaust holes 13 are evenly distributed on the observation tube 9 .

[0036] By setting a pressure member 19, wherein the pressure member 19 can be in the form of a fan, when the pressure member 19 is working, external air can enter the detection power box 4 through the vent 6 and be sprayed downward through the nozzle 20. The bottom of the detection power box 4 is connected with the outside, and the opening of the vent 6 is properly set. During the air flow, on the one hand, the equipment in the detection power box 4 can be cooled, and on the other hand, the air pressure in the detection power box 4 can be slightly higher than the external air pressure. When cracks appear on the cover plate, driven by pressure, the air will flow downward through the cracks and enter the observation tube 9, so that the powder or fine particles in the observation tube 9 can flow. At the same time, the excess air can be discharged to the outside through the exhaust hole 13 to avoid excessive air pressure in the observation tube 9.

[0037] In one embodiment of the present invention, see Figure 1-3 , the observation component comprises:

[0038] An observation panel 5, wherein the observation panel 5 is connected to the outer side wall of the detection power box 4;

[0039] A camera module A14, which is located on the inner wall of the observation tube 9 and connected to the observation panel 5; and

[0040] The camera module B16 is connected to the inner wall of the detection power box 4 , and the camera module B16 is also connected to the observation panel 5 .

[0041] By setting up camera module A14 and camera module B16, wherein camera module A14 and camera module B16 can both be in the form of cameras and connected to the observation panel 5, the images in the detection power box 4 and the observation tube 9 can be synchronously displayed on the observation panel 5. When the force plate 32 moves, the camera module B16 can make the staff know that the thrust piece 18 can start working normally. When cracks appear on the cover and the powder or fine particles in the observation tube 9 flow, they can be observed in time through the camera module A14 to timely understand the stress situation of the cover. The powder or fine particles in the observation tube 9 will not fly in large quantities during the working process to avoid dirt on the camera module A14, and it can be cleaned manually before each detection work, which will not be elaborated here.

[0042] In one embodiment of the present invention, see Figure 3 and Figure 4 , further comprising: a card slot 21, wherein the card slot 21 is evenly opened on the inner wall of the observation tube 9; and

[0043] The wire mesh cover 24 is connected to the card slot 21 by a card plate 23 .

[0044] The wire mesh cover 24 can be removed or installed from the observation tube 9 by the cooperation of the provided card slot 21 and the card plate 23. When cracks appear on the cover plate and debris falls, the provided wire mesh cover 24 can be used to collect the debris to prevent it from falling into the observation tube 9 and coming into contact with powder or fine particles, thereby affecting the observation of the staff. The enclosing effect of the wire mesh cover 24 can also prevent the debris from flying to the outside under the action of force and injuring people during the detection process.

[0045] In one embodiment of the present invention, see Figure 4 , further comprising: a foam ball 25, wherein the foam ball 25 is connected to the bottom of the steel mesh cover 24 through a thin steel wire 26.

[0046] By setting up thin steel wires 26, wherein the thin steel wires 26 have good toughness and are in several numbers, and a foam ball 25 is provided at the bottom end of each thin steel wire 26, during the detection process, through observation by the camera module A14, if the powder or fine particles inside the observation tube 9 do not flow, and the foam ball 25 shakes greatly, it proves that the force of the thrust piece 18 on the cover plate is unstable, and it should be readjusted before detection. On the other hand, when the force is balanced, the foam ball 25 will not shake greatly. When cracks appear, the foam ball 25 will shake due to the unbalanced force and the effect of wind pressure, thereby reminding the staff of the detection situation and further ensuring the accuracy of the detection result.

[0047] In one embodiment of the present invention, see Figure 1 , Figure 3 and Figure 6 , further comprising: a lifting frame 8, the lifting frame 8 is slidably connected to the cylindrical rod 2 through a sliding sleeve 3, the sliding sleeve 3 is sleeved on the cylindrical rod 2, and the lifting frame 8 is also connected to the protruding plate 31;

[0048] A connecting plate 30, the two ends of which are respectively connected to two adjacent sets of lifting frames 8;

[0049] a smooth rod 11, one end of which is connected to the bottom of the lifting frame 8, the other end of which is installed on the supporting platform 1 and is slidably connected to the supporting platform 1, and the smooth rod 11 is also connected to the observation tube 9; and

[0050] The laminating power member 15 is located on the supporting platform 1 , and a cross reinforcement plate 22 is fixedly mounted on the output end of the laminating power member 15 , and the cross reinforcement plate 22 is located on the bottom of the observation tube 9 .

[0051] The laminating power member 15 is provided, wherein the laminating power member 15 can be in the form of a hydraulic cylinder. When the laminating power member 15 is started, the cross reinforcement plate 22 can be pushed to drive the observation tube 9 to move upward, and the smooth rod 11 can be driven to slide in the supporting platform 1, which can play a guiding role, and the smooth rod 11 can drive the lifting frame 8 to slide upward on the cylindrical rod 2 through the sliding sleeve 3, thereby driving the cover plate to be tested on the protruding plate 31 to move upward synchronously until it contacts and presses the elastic pad 7 on the bottom of the detection power box 4. On the one hand, since the cover plate is heavy, the lifting frame 8 can drive the protruding plate 31 to be lowered to the lowest point during the initial work, so as to facilitate the staff to place the cover plate to be tested. On the other hand, under the action of the thrust of the laminating power member 15, the protruding plate 31 can push the cover plate to be in close contact with the bottom of the detection power box 4, thereby ensuring a certain air tightness and saving the external locking structure. At the same time, after the detection is completed, the lifting frame 8 moves downward, which is convenient for the staff to quickly remove the broken cover plate.

[0052] In one embodiment of the present invention, see Figure 1 and Figure 5 , further comprising: a first disturbance piece 12, wherein the first disturbance piece 12 is evenly distributed on the outer side wall of the observation tube 9 in the circumferential direction;

[0053] A disturbance circular sleeve 10, wherein the disturbance circular sleeve 10 is located on the supporting platform 1, and the disturbance circular sleeve 10 is sleeved on the observation tube 9; and

[0054] The second disturbance pieces 27 are evenly distributed on the inner wall of the disturbance sleeve 10 and are slidably connected to the first disturbance pieces 12 .

[0055] When the fitting power member 15 pushes the observation tube 9 to move up and down, the observation tube 9 can also be driven to move up and down in the disturbance circular sleeve 10. At this time, the first disturbance piece 12 on the observation tube 9 will collide with the second disturbance piece 27 in the disturbance circular sleeve 10, thereby causing the observation tube 9 to vibrate, so as to spread the powder or fine particles after the wind is blown on the inner bottom wall of the observation tube 9 for subsequent detection work.

[0056] In one embodiment of the present invention, see Figure 5 , further comprising: springs 29, the springs 29 being evenly distributed on the inner bottom wall of the disturbance sleeve 10; and

[0057] The backing plate 28 is connected to the spring 29 and is also detachably connected to the observation tube 9 .

[0058] By providing the pad 28 and the spring 29 , when the observation tube 9 moves downward into the disturbance sleeve 10 , it may first contact the pad 28 , and under the elastic action of the spring 29 , it may play a role of limiting and buffering.

[0059] In summary, when it is necessary to inspect the precast concrete cover plate, first, through the support platform 1, a roller is provided at the bottom of the support platform 1, and the whole inspection device can be moved to the designated position to facilitate the staff to place the cover plate, and then, through the protruding plate 31, the cover plate to be inspected can be inserted between the inspection power box 4 and the protruding plate 31, wherein the protruding plate 31 is located directly below the inspection power box 4, and through the elastic pad 7, wherein the elastic pad 7 is respectively located on the inspection power box 4 and the protruding plate 31, and in conjunction with the external clamping structure, such as in the form of bolt clamping, the cover plate can be fastened and placed between the inspection power box 4 and the protruding plate 31, and the cover plate is in close contact with the elastic pad 7. On the one hand, the friction between the cover plate and the elastic pad 7 can be increased to avoid shaking during the inspection process, and on the other hand, the sealing between the cover plate and the elastic pad 7 can be improved to provide conditions for subsequent observation work. When the precast cover plate is placed, the thrust assembly and the pressurizing assembly can be started to work. At the same time, the observation component is also put into operation. During the gradual downward movement of the thrust component, it can contact the cover plate at the bottom and exert an extruding force on the cover plate. As the pressure of the thrust component increases, when cracks appear on the cover plate, the pressurizing component can be operated in the form of exhausting air, so that the detection power box 4 can be placed in an environment slightly higher than the atmospheric pressure. On the one hand, the equipment in the detection power box 4 can be air-cooled. On the other hand, when cracks appear, high-pressure wind blows through the cracks into the observation tube 9, wherein the observation tube 9 is located directly below the cover plate, and powder or fine particles are arranged in the observation tube 9. Under the action of wind force, the powder can flow. At this time, through the observation component, it is convenient for the staff to understand the detection situation in a timely and rapid manner, so that the thrust component can be accurately shut down, so that when cracks that are not easy to detect appear during the detection process, the staff can understand the situation in a timely manner, thereby improving the detection results, ensuring the accuracy of the detection results, and providing convenience for the staff.
