Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction, and in particular to BIM subway station construction detection equipment. Background Art

[0002] BIM technology for subway construction optimizes design through 3D modeling and detects pipeline conflicts in advance; it monitors construction progress and quality in real time, improves the efficiency of multi-professional collaboration, reduces construction risks and costs, and ensures accurate and efficient progress of the project;

[0003] Patent application number CN202420372458.9 discloses a BIM subway station construction inspection device, which includes a striking assembly, a first mounting platform, and a second mounting platform. The striking assembly is mounted on the first mounting platform, and a universal ball is rotatably mounted on the second mounting platform. A connecting shaft extending in a vertical direction is pierced through the universal ball, and the upper end of the connecting shaft is fixedly connected to the bottom of the first mounting platform, and the lower end of the connecting shaft is fixedly connected to a counterweight block;

[0004] By performing knocking detection on the wall, we can determine whether there is a hollow area inside the wall. For some inclined walls, the knocking may be inclined to the wall, so that the force is dispersed to a larger area, which may mask the real sound of the hollow area, resulting in a decrease in the sound difference between the hollow and non-hollow areas, and causing misjudgment. Summary of the invention

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

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a BIM subway station construction detection equipment, including a collision block, the top of the collision block is fixedly connected to a connecting rod, the top of the connecting rod is movably connected to a pushing frame, the top of the pushing frame is fixedly connected to a holding handle, the bottom of the pushing frame is fixedly connected to a pushing spring, the bottom of the pushing spring is fixedly connected to the top of the collision block, the outer wall of the collision block is movably connected to a debris removal component, and the bottom of the pushing frame is movably connected to a positioning component;

[0007] The positioning components include:

[0008] An excitation sleeve, wherein the excitation sleeve is arranged at the bottom of the pushing frame;

[0009] Guide rods, two of which are provided and movably connected to the outer wall of the excitation sleeve, the outer walls of the two guide rods are movably connected to the excitation sleeve, and the push frame moves along the surface of the guide rods during the movement;

[0010] The positioning plates are provided with two, and the two positioning plates are fixedly connected to the outer wall of the excitation sleeve. The two positioning plates are in contact with the wall, so that the bottom surfaces of the two positioning plates are in the same plane. The closer the distance between the positioning plates, the closer the plane where the bottom surfaces of the two positioning plates are located is to the plane of the target knocking surface. Since the impact block is restricted by the connecting rod to be perpendicular to the surface formed by the bottom surfaces of the positioning plates, when the bottom surfaces of the two positioning plates are in contact with the wall, the direction in which the impact block impacts is as perpendicular to the wall as possible.

[0011] Preferably, both sides of the positioning plate are movably connected with positioning pins, the top of the positioning pin is fixedly connected with a fitting spring, the top of the fitting spring is fixedly connected to the outer wall of the positioning plate, and the outer wall of the positioning pin is fixedly connected with a calibration rod on the side facing the corresponding positioning plate. When the positioning plate is fitted with the wall, the positioning pin will be pushed against the surface of the wall under the push of the fitting spring. Since the bottom of the positioning pin is in a sharp shape, it can avoid friction between the positioning plate and the wall. When there is an inclination angle between the bottom surface of the positioning plate and the wall, the two positioning pins on the positioning plate will be pushed by the fitting spring at different distances. The inclination angle can be judged by observing the distance between the two corresponding calibration rods, which is conducive to making the impact direction of the impact block as perpendicular to the wall as possible.

[0012] Preferably, the excitation sleeve is internally movably connected with two locking plates, the inner wall of the excitation sleeve is located at the bottom of the corresponding locking plate and is fixedly connected with a limiting rod, the limiting protrusion can limit the rotation direction of the locking plate, the outer wall of the impact block is located at the top of the locking plate and is fixedly connected with a limiting protrusion, the rotation direction of the locking plate is limited by the limiting protrusion, and the locking plate will be intercepted by the locking plate due to the existence of the limiting protrusion. When the impact block is pushed, it cannot push the corresponding two locking plates, so that the position of the impact block is limited.

[0013] Preferably, the bottom of the locking plate is fixedly connected with an elastic sheet, the elastic sheet is elastic, and the elastic sheet is a metal sheet with the ability to restore its shape after deformation. The elastic sheet is elastic, and the elastic sheet is a metal sheet with the ability to restore its shape after deformation. The bottom of the elastic sheet is fixedly connected with a support plate, and the support plate is fixedly connected to the outer wall of the excitation sleeve.

[0014] Preferably, the outer wall of the pushing frame is fixedly connected to two excitation plates, and the excitation plates are located on the top of the corresponding locking plates. When the pushing frame continues to move toward the excitation sleeve, it will eventually push the outer side of the corresponding locking plate, causing the connection between the locking plate and the excitation sleeve to rotate.

[0015] Preferably, the debris removal component includes a fixed sleeve, which is movably connected to the outer wall of the impact block, and a rubber ring is fixedly connected to the bottom of the fixed sleeve. The rubber ring is made of soft rubber and will be deformed by pressure, so that the rubber ring can be better integrated with the wall.

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

[0017] Preferably, an opening is provided on the top of the fixing sleeve, and the top of the fixing sleeve is fixedly connected to a limiting sleeve at the top corresponding to the opening, and a closing piece is movably connected inside the limiting sleeve. When the rubber ring fits against the wall, when the external air pressure is higher than that inside the fixing sleeve, the gas inside the fixing sleeve will be discharged to the outside through the opening, and when the air pressure inside the fixing sleeve is lower than that inside the outside, the external air pressure will push the closing piece to seal the air hole.

[0018] Preferably, the impact block is fixedly connected to a limiting frame inside, and a rubber block is fixedly connected to the limiting frame inside. The limiting frame serves to limit the movement direction of the rubber block to ensure that the rubber block is in the same straight line as the movement direction of the impact block under the push of inertia. When the impact block stops at the moment of hitting the wall, the rubber block will continue to move under the action of inertia, and the impact block will then move in the opposite direction due to the rebound of the wall and collide with the rubber block, thereby reducing the impact of the impact block after rebound.

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

[0020] 1. The BIM subway station construction inspection equipment fits the wall with two positioning plates, which makes the bottom surfaces of the two positioning plates 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 hits the wall along the direction of the connecting rod, avoiding the impact of the impact block and the wall due to excessive inclination, producing the sound of erroneous judgment, and thus improving the accuracy of the detection.

[0021] 2. The BIM subway station construction inspection equipment makes the bottom surface of the positioning plate fit with the wall surface, so that the direction of the impact block hitting the wall surface is as vertical as possible. The fixing sleeve makes the axis line of the guide rod and the movement direction of the impact block in the same straight line. Under the action of the impact, the bottom surface of the rubber ring will fit with the wall surface as much as possible. The impact block rebounds after the impact and hits the wall again under the action of the spring. The sound is blocked by the rubber ring, reducing the propagation of sound, avoiding the propagation of messy sound, and interfering with the sound of the first impact. It can improve the accuracy of human judgment and improve the accuracy of detection.

[0022] 3. The BIM subway station construction inspection equipment discharges the internal air through the opening of the fixed sleeve. When the impact block rebounds after impact, the impact block will be gradually pulled out from the inside of the fixed sleeve to the outside, increasing the space inside the fixed sleeve. When the impact block rebounds, it will be subject to the resistance of air pressure to suppress the rebound distance. At the same time, the impact of the rubber block is combined to reduce the impact of the impact block after rebound, thereby reducing the sound of the rebound impact, reducing the interference of noise to people, and improving accuracy.

[0023] 4. The BIM subway station construction inspection equipment has a relatively small overall design and is easy to carry. After measuring a single position on the wall, the excitation sleeve will be pulled in the direction of the positioning plate, which will quickly reset the entire device to the state before use, and then it can quickly impact the wall at multiple points for rapid detection.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a BIM subway station construction detection device, comprising 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, a debris 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 comprises:

[0038] The exciting sleeve 61 is arranged at the bottom of the pushing frame 3;

[0039] Guide rods 62, two guide rods 62 are provided, and the two guide rods 62 are movably connected to the outer wall of the excitation sleeve 61, and the outer walls of the two guide rods 62 are movably connected to the excitation sleeve 61, and the push frame 3 moves along the surface of the guide rods 62 during the movement;

[0040] There are two positioning plates 63, and 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, which will make the bottom surfaces of the two positioning plates 63 on the same plane. The closer the distance between the positioning plates 63, the closer the plane where the bottom surfaces of the two positioning plates 63 are located is to the plane of the target striking surface. Since the impact block 1 is restricted by the connecting rod 2 to be perpendicular to the surface formed by the bottom surfaces of the positioning plates 63, when the bottom surfaces of the two positioning plates 63 are in contact with the wall, the impact direction of the impact block 1 is as perpendicular to the wall as possible.

[0041] The top of the positioning pin 610 is fixedly connected to the outer wall of the positioning plate 63, and the outer wall of the positioning pin 610 is fixedly connected to a calibration rod 612 on the side of the positioning pin 610 that faces the corresponding positioning plate 63. When the positioning plate 63 is in contact with the wall, the positioning pin 610 will be pushed against the surface of the wall by the fitting spring 611. Since the bottom of the positioning pin 610 is in a sharp shape, it can avoid the friction between the positioning plate 63 and the wall. When there is an inclination angle between the bottom surface of the positioning plate 63 and the wall, the two positioning pins 610 on the positioning plate 63 will be pushed by the fitting spring 611 at different distances. The inclination angle can be judged by observing the distance between the two corresponding calibration rods 612, which is conducive to making the impact direction of the impact block 1 as perpendicular to the wall as possible.

[0042] By holding the two holding handles 4 with both hands, the bottom surface of the positioning plate 63 is fitted against the wall, and the holding handles 4 are pushed toward the wall, so that the pushing frame 3 is pushed toward the excitation sleeve 61 along with the holding handles 4. During the movement, the pushing frame 3 moves 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 as possible.

[0043] There are two locking plates 65 movably connected inside the excitation sleeve 61, and the inner wall of the excitation sleeve 61 is located at the bottom of the corresponding locking plate 65 and is fixedly connected with a limiting rod 66. The limiting protrusion 64 can limit the rotation direction of the locking plate 65. The outer wall of the impact block 1 is located at the top of the locking plate 65 and is fixedly connected with a limiting protrusion 64. The rotation direction of the locking plate 65 is limited by the limiting protrusion 64, and the locking plate 65 will be intercepted by the locking plate 65 due to the existence of the limiting protrusion 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 limited.

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

[0052] At the moment when the impact block 1 is pushed by the push spring 5, the fixing sleeve 71 will stop in place under the action of inertia, and then the upper limiting ring 73 will fit with the fixing sleeve 71 under the drive of the impact block 1, and push the fixing sleeve 71 as the impact block 1 moves. When the impact block 1 hits the wall and stops, the fixing sleeve 71 will hit the wall together with the rubber ring 72 due to inertia. The rubber ring 72 is made of a relatively soft material. Since the bottom surface of the positioning plate 63 fits the wall, the direction in which the impact block 1 hits the wall will be as vertical as possible. The fixing sleeve 71 will make the axis of the guide rod 62 and the movement direction of the impact block 1 in the same straight line. Under the action of the impact, the bottom surface of the rubber ring 72 will fit the wall as much as possible. The impact block 1 rebounds after the impact and hits the wall again under the action of the spring. The sound is blocked by the rubber ring 72, thereby reducing the propagation of the sound.

[0053] An opening is provided on the top of the fixing sleeve 71, and the top of the fixing sleeve 71 is fixedly connected to a limiting sleeve 75 corresponding to the top of the opening. A closing piece 76 is movably connected inside the limiting sleeve 75. When the rubber ring 72 is in contact with the wall, when the external air pressure is higher than that inside the fixing sleeve 71, the gas inside the fixing sleeve 71 will be discharged to the outside through the opening; when the air pressure inside the fixing sleeve 71 is lower than that inside the outside, the external air pressure will push the closing piece 76 to seal the air hole.

[0054] When the fixing sleeve 71 pushes the rubber ring 72 to collide with the wall, the rubber ring 72 will be deformed, which causes the volume of the space formed by the fixing sleeve 71, the rubber ring 72 and the wall to decrease, and then the air inside the fixing sleeve 71 will be discharged through the opening. When the impact block 1 rebounds after the impact, the impact block 1 will be gradually pulled outward from the inside of the fixing sleeve 71, thereby increasing the space inside the fixing sleeve 71 and reducing the air pressure inside the fixing sleeve 71. The external air pressure will push the closing piece 76 to close the air hole, which makes the impact block 1 encounter the resistance of the air pressure when rebounding, so as to suppress the rebound distance, thereby reducing the impact of the impact block 1 after the rebound, and then reducing the impact sound of the rebound.

[0055] The impact block 1 is internally fixedly connected to a limiting frame 78, and the limiting frame 78 is internally fixedly connected to a rubber block 77. The limiting frame 78 serves to limit the movement direction of the rubber block 77 to ensure that the movement direction of the rubber block 77 is in the same straight line as the impact block 1 under the push of inertia.

[0056] When the impact block 1 is pushed to hit the wall, the rubber block 77 will be pushed to move together through the inner wall. When the impact block 1 stops hitting the wall, the rubber block 77 will continue to move under the action of inertia. The impact block 1 will then move in the opposite direction due to the rebound of the wall, and then collide with the rubber block 77, thereby reducing the amplitude of the rebound of the impact block 1.

[0057] 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.
