Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction, and specifically to a BIM subway station construction detection device. Background Art

[0002] The BIM technology for subway construction optimizes the design through three-dimensional modeling, detects pipeline conflicts in advance; monitors the construction progress and quality in real time, improves the collaborative efficiency of multiple specialties, reduces construction risks and costs, and ensures the accurate and efficient progress of the project;

[0003] The patent with the application number CN202420372458.9 discloses a BIM subway station construction detection device, which includes a striking component, a first installation platform, and a second installation platform. The striking component is installed on the first installation platform. A universal ball is rotatably installed on the second installation platform. A connecting shaft extending in the vertical direction passes through the universal ball. The upper end of the connecting shaft is fixedly connected to the bottom of the first installation platform, and the lower end of the connecting shaft is fixedly connected with a counterweight;

[0004] By knocking on the wall to detect whether there is a hollow area inside the wall. For some inclined walls, it may cause the knocking to be inclined to the wall surface, dispersing the force over a larger area, which may cover up the true sound of the hollow area, resulting in a reduction in the sound difference between the hollow and non-hollow areas and causing misjudgment. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a BIM subway station construction detection device to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A BIM subway station construction detection device includes an impact block. The top of the impact block is fixedly connected with a connecting rod. The top of the connecting rod is movably connected with a push frame. The top of the push frame is fixedly connected with a holding handle. The bottom of the push frame is fixedly connected with a push spring. The bottom of the push spring is fixedly connected with the top of the impact block. The outer wall of the impact block is movably connected with a cleaning component. The bottom of the push frame is movably connected with a positioning component;

[0007] The positioning component includes:

[0008] An excitation sleeve, which is arranged at the bottom of the push frame;

[0009] Guide rods. There are two guide rods, and the two guide rods are movably connected to the outer wall of the excitation sleeve. The outer walls of the two guide rods are also movably connected to the excitation sleeve. The push frame will move along the surface of the guide rods during the movement;

[0010] Positioning plates. There are two positioning plates, and both of the two positioning plates are fixedly connected to the outer wall of the excitation sleeve. When the two positioning plates are in contact with the wall surface, the bottom surfaces of the two positioning plates will be on the same plane. The closer the distance between the positioning plates is, the closer the plane where the bottom surfaces of the two positioning plates are located is to the plane of the target knocking surface. And since the impact block is restricted by the connecting rod to be perpendicular to the surface formed by the bottom surface of the positioning plate, when the bottom surfaces of the two positioning plates are in contact with the wall surface, the impact direction of the impact block is made as perpendicular to the wall as possible.

[0011] Preferably, positioning pins are movably connected to both sides of the positioning plate. A fitting spring is fixedly connected to the top of the positioning pin, and the top of the fitting spring is fixedly connected to the outer wall of the positioning plate. A calibration rod is fixedly connected to one side of the outer wall of the positioning pin facing the corresponding positioning plate. When the positioning plate is in contact with the wall surface, the positioning pin will be pushed by the fitting spring and press against the surface of the wall. Since the bottom of the positioning pin is sharp, it can prevent the positioning plate from rubbing against the wall. And when there is an inclination angle between the bottom surface of the positioning plate and the wall, the distances that the two positioning pins on the positioning plate are pushed by the fitting spring will be different. The inclination angle can be judged by observing the distance between the two corresponding calibration rods, which is beneficial to making the impact direction of the impact block as perpendicular to the wall as possible.

[0012] Preferably, two locking plates are movably connected inside the excitation sleeve. Limit rods are fixedly connected to the inner wall of the excitation sleeve at the bottom of the corresponding locking plates. The limiting convex blocks can limit the rotation direction of the locking plates. Limiting convex blocks are fixedly connected to the outer wall of the impact block at the top of the locking plates. The rotation direction of the locking plate is restricted by the limiting convex block, and the impact block will be intercepted by the locking plate due to the existence of the limiting convex block. When the impact block is pushed, it cannot push the corresponding two locking plates, so that the position of the impact block is restricted.

[0013] Preferably, elastic sheets are fixedly connected to the bottoms of the locking plates. The elastic sheets are elastic. The elastic sheets are metal sheets that have the ability to restore their shape after deformation. The elastic sheets are elastic. The elastic sheets are metal sheets that have the ability to restore their shape after deformation. Support plates are fixedly connected to the bottoms of the elastic sheets, and the support plates are fixedly connected to the outer wall of the excitation sleeve.

[0014] Preferably, two excitation plates are fixedly connected to the outer wall of the pushing frame, and the excitation plates are located at the top of the corresponding locking plates. When the pushing frame continuously moves towards the excitation sleeve, it will finally push the outside of the corresponding locking plate, causing the connection between the locking plate and the excitation sleeve to rotate.

[0015] Preferably, the impurity removal component includes a fixed sleeve. The fixed sleeve is movably connected to the outer wall of the impact block. A rubber ring is fixedly connected to the bottom of the fixed sleeve. The rubber ring is made of soft rubber and will deform under the push of pressure, enabling the rubber ring to fit well with the wall.

[0016] Preferably, an upper limiting ring is fixedly connected to the outer wall of the impact block at the top of the fixed sleeve, and a lower limiting ring is fixedly connected to the outer wall of the impact block at the bottom of the upper limiting ring. The lower limiting ring and the upper limiting ring jointly limit the movement range of the fixed sleeve.

[0017] Preferably, an opening is provided at the top of the fixed sleeve, and a limiting sleeve is fixedly connected to the top of the fixed sleeve corresponding to the opening. A closing piece is movably connected inside the limiting sleeve. When the rubber ring is in contact with the wall surface and the external air pressure is higher than that inside the fixed sleeve, the gas inside the fixed sleeve will be discharged to the outside through the opening. When the air pressure inside the fixed sleeve is lower than the outside, the external air pressure will push the closing piece to close the air hole.

[0018] Preferably, a limiting frame is fixedly connected inside the impact block, and a rubber block is fixedly connected inside the limiting frame. The limiting frame plays a role in restricting the movement direction of the rubber block to ensure that the rubber block moves in the same straight line as the impact block under the action of inertia. When the impact block hits the wall and stops for a moment, the rubber block will continue to move under the action of inertia. Subsequently, the impact block will be pushed back by the wall and move in the opposite direction, hitting the rubber block, thereby reducing the impact after the impact block rebounds.

[0019] The present invention provides a BIM subway station construction detection device, which has the following beneficial effects:

[0020] 1. For this BIM subway station construction detection device, when the two positioning plates are in contact with the wall surface, the bottom surfaces of the two positioning plates will be on the same plane, so that the impact direction of the impact block is as perpendicular to the wall as possible, and the impact block impacts the wall along the direction of the connecting rod, avoiding the impact of the impact block on the wall with excessive inclination and generating misjudged sounds, thereby improving the detection accuracy.

[0021] 2. For this BIM subway station construction detection device, due to the bottom surface of the positioning plate being in contact with the wall surface, the impact direction of the impact block is as perpendicular to the wall as possible. The fixed sleeve makes the axis line of the guide rod be in the same straight line as the movement direction of the impact block. Under the action of impact, the bottom surface of the rubber ring will be in contact with the wall as much as possible. The sound of the impact block rebounding after impact and then hitting the wall again under the action of the spring is blocked by the rubber ring, reducing the sound transmission, avoiding the interference of messy sound transmission on the sound of the first impact, and being able to improve the accuracy of human judgment, thus improving the detection accuracy.

[0022] 3. The BIM subway station construction detection device discharges the internal air through the holes in the fixing sleeve. When the impact block rebounds after being impacted, the impact block will gradually pull outwards from the inside of the fixing sleeve, increasing the space inside the fixing sleeve. When the impact block rebounds, it will be subjected to air pressure resistance to inhibit the rebound distance. At the same time, it cooperates with the impact of the rubber block to reduce the impact after the impact block rebounds, thereby reducing the sound of the rebound impact and reducing the interference of the noise to people, so as to improve the accuracy.

[0023] 4. The BIM subway station construction detection device is designed to be relatively small and portable. After measuring a single position on the wall, when the excitation sleeve is pulled towards the orientation of the positioning plate, the whole device can be quickly reset to the state before use, and then it can quickly impact multiple positions on the wall, facilitating rapid detection.

Detailed implementation mode

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] Embodiment 1: Please refer to Figure 1-8 , the present invention provides a technical solution: a BIM subway station construction detection device, including an impact block 1, a connecting rod 2 is fixedly connected to the top of the impact block 1, a pushing frame 3 is movably connected to the top of the connecting rod 2, a holding handle 4 is fixedly connected to the top of the pushing frame 3, a pushing spring 5 is fixedly connected to the bottom of the pushing frame 3, the bottom of the pushing spring 5 is fixedly connected to the top of the impact block 1, an impurity removal component 7 is movably connected to the outer wall of the impact block 1, and a positioning component 6 is movably connected to the bottom of the pushing frame 3;

[0037] The positioning component 6 includes:

[0038] A firing sleeve 61, and the firing sleeve 61 is arranged at the bottom of the pushing frame 3;

[0039] Guide rods 62, there are two guide rods 62, and the two guide rods 62 are movably connected to the outer wall of the firing sleeve 61, and the outer walls of the two guide rods 62 are both movably connected to the firing sleeve 61. During the movement of the pushing frame 3, it will move along the surface of the guide rod 62;

[0040] The positioning plates 63 are provided with two, and both of the two positioning plates 63 are fixedly connected to the outer wall of the excitation sleeve 61. The two positioning plates 63 are in contact with the wall surface, which will make the bottom surfaces of the two positioning plates 63 in the same plane. The closer the distance between the positioning plates 63 is, the closer the plane where the bottom surfaces of the two positioning plates 63 are located is to the plane of the target knocking surface. And since the impact block 1 is restricted by the connecting rod 2 to be perpendicular to the plane formed by the bottom surface of the positioning plate 63, when the bottom surfaces of the two positioning plates 63 are in contact with the wall surface, the impact direction of the impact block 1 is made as perpendicular to the wall surface as possible.

[0041] Positioning pins 610 are movably connected to both sides of the positioning plate 63. The top of the positioning pin 610 is fixedly connected to a fitting spring 611, and the top of the fitting spring 611 is fixedly connected to the outer wall of the positioning plate 63. A calibration rod 612 is fixedly connected to the side of the outer wall of the positioning pin 610 facing the corresponding positioning plate 63. When the positioning plate 63 is in contact with the wall surface, the positioning pin 610 will be pushed by the fitting spring 611 to abut against the surface of the wall. Since the bottom of the positioning pin 610 is in a sharp shape, it can prevent the positioning plate 63 from rubbing against the wall surface. And when there is an inclination angle between the bottom surface of the positioning plate 63 and the wall surface, the distances that the two positioning pins 610 on the positioning plate 63 are pushed by the fitting spring 611 will be different. The inclination angle can be judged by observing the distance between the two corresponding calibration rods 612, which is beneficial to making the impact direction of the impact block 1 as perpendicular to the wall surface as possible.

[0042] Hold the two holding handles 4 with both hands so that the bottom surface of the positioning plate 63 is in contact with the wall surface, and push the holding handle 4 towards the wall, so that the pushing frame 3 moves towards the excitation sleeve 61 along with the holding handle 4. During the movement of the pushing frame 3, it will move along the surface of the guide rod 62 to ensure that the moving direction of the impact block 1 is as perpendicular to the wall surface as possible.

[0043] Two locking plates 65 are movably connected inside the excitation sleeve 61. Limiting rods 66 are fixedly connected to the inner wall of the excitation sleeve 61 at the bottom of the corresponding locking plates 65. The limiting convex blocks 64 can limit the rotation direction of the locking plates 65. Limiting convex blocks 64 are fixedly connected to the top of the outer wall of the impact block 1 at the positions of the locking plates 65. The rotation direction of the locking plates 65 is restricted by the limiting convex blocks 64, and the impact block 1 will be blocked by the locking plates 65 due to the existence of the limiting convex blocks 64. When the impact block 1 is pushed, it cannot push the corresponding two locking plates, so that the position of the impact block 1 is restricted.

[0044] The rotation direction of the locking plate 65 is limited by the limiting protrusion 64, so that when the pushing frame 3 is pushed, the impact block 1 will be pushed through the pushing spring 5, and will be intercepted by the locking plate 65 due to the existence of the limiting protrusion 64, so that the position of the impact block 1 is limited, which makes the pushing spring 5 continuously compressed, so that the pushing spring 5 continuously accumulates the impact force, and then the impact block 1 can be pushed to hit the wall with a larger force during the impact, so that the sound generated can be better distinguished.

[0045] The bottom of the locking plate 65 is fixedly connected with an elastic sheet 67, the bottom of the elastic sheet 67 is fixedly connected with a support plate 68, and the support plate 68 is fixedly connected to the outer wall of the excitation sleeve 61. The elastic sheet 67 is elastic and is a metal sheet that has the ability to restore its shape after deformation.

[0046] Two excitation plates 69 are fixedly connected to the outer wall of the pushing frame 3, and the excitation plates 69 are located on the top of the corresponding locking plates 65. When the pushing frame 3 continues to move toward the excitation sleeve 61, it will eventually push the outer side of the corresponding locking plate 65, causing the connection between the locking plate 65 and the excitation sleeve 61 to rotate.

[0047] When the pushing frame 3 is continuously pushed toward the wall, the excitation plate 69 will eventually push the outside of the locking plate 65 and compress the elastic sheet 67, so that the part of the locking plate 65 located inside the excitation sleeve 61 will rotate upward and the locking plate 65 will fall off the bottom of the limiting protrusion 64. At this time, the limiting protrusion 64 is no longer stuck in the position of the locking plate 65. The impact block 1 will hit the wall under the push of the pushing spring 5, and the sound produced by the impact can be used to judge whether there is an empty area in the wall.

[0048] After use, pulling the excitation sleeve 61 in the direction of the positioning plate 63 will cause the limiting protrusion 64 to push the locking plate 65, causing the locking plate 65 to press the elastic sheet 67 to deform until the limiting protrusion 64 is located at the top of the locking plate 65. At this time, the locking plate 65 will rotate under the elastic force of the elastic sheet 67, fit with the limiting rod 66, and be located at the bottom of the locking plate 65, which is convenient for quickly performing the next strike.

[0049] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution:

[0050] The debris removal component 7 includes a fixed sleeve 71, which is movably connected to the outer wall of the impact block 1. A rubber ring 72 is fixedly connected to the bottom of the fixed sleeve 71. The rubber ring 72 is made of soft rubber and will be deformed by pressure, so that the rubber ring 72 can be better integrated with the wall.

[0051] On the outer wall of the impact block 1, there is an upper limiting ring 73 fixedly connected to the top of the fixed sleeve 71. On the outer wall of the impact block 1, there is a lower limiting ring 74 fixedly connected to the bottom of the upper limiting ring 73. The lower limiting ring 74 and the upper limiting ring 73 jointly limit the movement range of the fixed sleeve 71.

[0052] At the moment when the impact block 1 is pushed by the spring 5, the fixed sleeve 71 will stay in place under the action of inertia. Subsequently, the upper limiting ring 73 will fit with the fixed sleeve 71 under the drive of the impact block 1 and push the fixed sleeve 71 along with the movement of the impact block 1. When the impact block 1 hits the wall and stops, due to inertia, the fixed sleeve 71 will hit the wall together with the rubber ring 72. The material of the rubber ring 72 is relatively soft. Since the bottom surface of the positioning plate 63 is in contact with the wall, it will make the impact direction of the impact block 1 as perpendicular to the wall as possible. The fixed sleeve 71 will make the axis line of the guide rod 62 in the same straight line as the movement direction of the impact block 1. Under the action of the impact, it will make the bottom surface of the rubber ring 72 fit with the wall as much as possible. The sound of the impact block 1 rebounding after the impact and hitting the wall again under the action of the spring is blocked by the rubber ring 72, reducing the sound transmission.

[0053] There is an opening on the top of the fixed sleeve 71. At the top of the corresponding opening on the top of the fixed sleeve 71, there is a limit sleeve 75 fixedly connected. Inside the limit sleeve 75, there is a closing piece 76 movably connected. When the rubber ring 72 is in contact with the wall and the external air pressure is higher than the inside of the fixed sleeve 71, the gas inside the fixed sleeve 71 will be discharged to the outside through the opening. When the air pressure inside the fixed sleeve 71 is lower than the outside, the external air pressure will push the closing piece 76 to close the air hole.

[0054] When the fixed sleeve 71 pushes the rubber ring 72 to hit and fit with the wall, it will cause the rubber ring 72 to deform, which results in a process of decreasing the volume of the space formed by the fixed sleeve 71 and the rubber ring 72 with the wall. As a result, the air inside the fixed sleeve 71 will be discharged through the opening. When the impact block 1 rebounds after the impact, it will gradually pull outwards from the inside of the fixed sleeve 71, increasing the space inside the fixed sleeve 71 and reducing the air pressure inside the fixed sleeve 71. The external air pressure will push the closing piece 76 to close the air hole. This makes the impact block 1 be subject to air pressure resistance when rebounding, inhibiting the rebounding distance, thereby reducing the impact after the impact block 1 rebounds and further reducing the sound of the rebounding impact.

[0055] Inside the impact block 1, there is a limit frame 78 fixedly connected. Inside the limit frame 78, there is a rubber block 77 fixedly connected. The limit frame 78 plays a role in restricting the movement direction of the rubber block 77 to ensure that the rubber block 77 moves in the same straight line as the movement direction of the impact block 1 under the push of inertia.

[0056] When the impact block 1 is pushed to impact the wall surface, it will push the rubber block 77 to move together through the inner wall. At the moment when the impact block 1 stops hitting the wall surface, the rubber block 77 will continue to move under the action of inertia. Subsequently, the impact block 1 will be subjected to the rebound effect of the wall surface and move in the reverse direction, and then collide with the rubber block 77, thereby reducing the amplitude of the rebound of the impact block 1.

[0057] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
