Description

Technical Field

[0001] The invention belongs to the technical field of metal template detection devices, and in particular relates to a beam and slab prefabricated steel template flatness and travel detection device. Background Art

[0002] Steel formwork is a steel formwork used for concrete pouring. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects due to its multiple uses and beautiful concrete pouring. Steel formwork can replace wooden formwork, significantly reducing the pore water pressure and air bubble removal in the concrete pressure usually associated with traditional sealing formwork such as wood, plywood, and steel plate; after the steel formwork structure concrete is poured and formed, an ideal rough interface is formed. No roughing operation is required to proceed to the next process.

[0003] During the flatness inspection of prefabricated steel formwork, if the formwork is contaminated with granular impurities, pebbles, and mud blocks that affect the measurement structure, the measuring wheel of the road surface flatness meter or the laser rangefinder will produce errors in the measurement results when passing through pebbles and mud blocks, resulting in poor flatness inspection data. The entire inspection process also requires workers to hold a steel ruler for multi-point measurements, which is not only time-consuming and labor-intensive, but may also affect the accuracy of the inspection results due to factors such as worker hand tremors. In addition, under normal circumstances, the entire flatness inspection process often requires workers to manually record and organize measurement data, which is cumbersome and prone to errors. The measurement results are usually presented in numerical form, which makes it difficult to intuitively reflect the flatness of the floor tiles and is not conducive to discovering and locating problem areas. Summary of the invention

[0004] The purpose of the present invention is to provide a flatness and walking detection device for prefabricated steel formwork for beams and slabs, so as to solve the problem that the measuring wheel of a road surface flatness meter or a laser rangefinder will produce errors in the measurement results when passing through small stones or mud blocks, resulting in poor flatness detection data.

[0007] Furthermore, the detection component includes an intermediate plate fixed on the second telescopic rod, the top and bottom of the intermediate plate are movably abutted against guide plates, the guide plate is connected with a friction pad along the height direction of the side wall of the moving frame, and both ends of the guide plate are integrally connected with a resistance rod, the outside of the resistance rod is placed on the second spring on the side wall of the moving frame, and one end of the second spring is fixedly installed with a fixed block connected to the resistance rod limit.

[0008] Furthermore, a side of the fixing block close to the middle plate is connected with an inclined surface, and the fixing block is symmetrically arranged relative to the center of the guide plate.

[0009] Furthermore, it also includes a rotating cleaning mechanism, which includes a second slider fixed on the first screw shaft, a strip plate installed on the outer wall of the second slider, a third slider movably connected at the center position of the strip plate, and movable plates are slidably connected at both ends of the bottom of the second slider, the third slider and the protrusion of the turntable are connected by a first swing rod, and the extended end of the bottom of the third slider and the movable plate are connected by a second swing rod.

[0010] Furthermore, the movable plate is rotatably connected to a movable shaft, one end of the movable shaft is connected to a ring-shaped array of cleaning brushes, and the other end is connected to a first gear through a tensioning belt transmission. One end of the first gear is fixed to the output shaft of the third motor, and the outer wall of the first gear is meshed with a second gear corresponding to the tensioning belt.

[0011] Furthermore, the first gear, the second gear and the output shaft of the third motor are all placed outside in a cover body fixed on the second slider, and the movable plate is connected to the limiting groove along the length direction of the second slider.

[0012] Furthermore, both ends of the first swing rod are mounted on the protrusion of the turntable and the third slider by a rotational connection, and both ends of the second swing rod are mounted on the third slider and the movable plate by a rotational connection, and the second swing rods are staggered up and down.

[0013] Furthermore, a panel is fixedly installed on the top of the lifting block, and a slot is opened on the panel. A second screw shaft fixed on the turning handle is installed at the slot, and a fourth slider is spirally driven on the second screw shaft. Both ends of the fourth slider are clamped with marking pens through arc plates, and a drawing board fixed on the movable frame is provided on one side of the marking pen.

[0014] Furthermore, the drawing board is connected to the inner wall of the beam by means of a clip-on fixation, one end of the beam is fixed on the movable frame, and a rectangular groove is connected to the top of the beam in the length direction and is movably connected to a U-shaped rod, one end of the U-shaped rod is pressed against the outer wall of the drawing board, and positioning holes are provided on both sides of the bottom end of the drawing board and locked and fixed by adjusting bolts.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) A walking detection mechanism is provided. By pushing the handle on the moving frame, the entire detection device is pushed to the corresponding position point of the steel template. After the first motor is started, the first slider drives the detection component to move horizontally through the screw transmission, and then performs the horizontal detection work on the steel template. When the X-axis direction of the horizontal surface of the steel template is uneven, the detection component will move up and down under the elastic expansion and contraction of the first spring and the free up and down movement of the first telescopic rod. At the same time, the position point generated by the marking pen on the lifting block during the drawing process will effectively reflect the flatness of the steel template. In addition, the lifting block can drive the middle plate to move up and down during the up and down movement. Since the middle plate and the guide plate are in active contact and fit, the gap between the middle plate and the guide plate is closed at the initial position. When the guide plate is moved by the force, the friction pad uses the friction resistance to fix the guide plate. In addition, the fixed block on the second spring cooperates with the contact rod to further fix the moved guide plate at the corresponding height position. By directly observing whether there is a gap between the middle plate and the guide plate, it can be concluded whether the steel template is flat. The operation is convenient for personnel and the detection accuracy is improved.

[0016] (2) A ball assembly is provided. When the second motor is started, it can drive the turntable to rotate. The turntable can also drive the ball assembly to rotate together. Since the second motor is fixed on the lifting block, when the ball assembly rotates, the flatness of the horizontal plane in the area in the X-axis and Y-axis directions can be detected. If the flatness of any horizontal plane in the area is not good, the force can be transmitted to the lifting block to make it shake up and down. The ball assembly is movably connected to the ball through the arc surface on the sleeve, and the top cover is installed on the turntable by a threaded connection. While ensuring the effective rotation of the ball assembly and preventing the sleeve from falling off, it can also facilitate the detachable installation work between personnel, thereby improving work efficiency, effectively increasing the detection range, and avoiding the occurrence of missed detection areas.

[0017] (3) A rotating cleaning mechanism is provided. After the third motor is started, it can drive the rotation of the first gear. Under the gear meshing transmission action and in conjunction with the transmission connection of the tensioning belt, the cleaning brushes on the movable plates at both ends can be rotated for cleaning, thereby effectively removing the granular impurities in the front section of the steel template and preventing the external granular impurities from affecting the flatness detection accuracy. At the same time, during the rotation of the turntable, the third slider on the strip plate can be driven to move forward and backward through the rotation action of the crank connecting rod, and then through the rotation connection action of the second swing rod, during the movement of the third slider forward and backward, the movable plate can be driven to move in the opposite direction in the Y-axis direction of the horizontal plane. Since the tensioning belt is made of elastic material and has a certain elasticity, the movable plate can still transmit power to the movable shaft during the horizontal movement and can move normally. During the rotation of the cleaning brush, the Y-axis movement in the horizontal plane can be performed at the same time, thereby effectively expanding the cleaning range and promoting the orderly progress of the detection work.

[0021] 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.

[0022] Reference Manual Attached Figure 1 ~Attached Figure 5 As shown, a beam and slab prefabricated steel template flatness and walking detection device comprises: a moving frame 1; a walking detection mechanism 2, the walking detection mechanism 2 comprises a first motor 3 fixed on the moving frame 1, the output shaft of the first motor 3 extends to the first screw shaft 4, the first screw shaft 4 is spirally driven with a first slider 5, the first slider 5 is connected with a guide groove along the length direction of the guide column 6 on the moving frame 1, and the extended ends at both ends of the first slider 5 are connected with a lifting block 8 through a first telescopic rod 7, and the lifting block 8 is connected to the bracket on the first slider 5 through a first spring 9; A second motor 10 is fixedly installed at the center of the bottom end of the lifting block 8, and the output shaft of the second motor 10 extends to the turntable 11. The protrusion at the bottom of the turntable 11 is connected to a ball assembly 12 that performs circular motion, and the fixed rods on both sides of the lifting block 8 are connected to a detection assembly 14 that performs vertical motion through a second telescopic rod 13. The ball assembly 12 includes a top cover 15 with a threaded hole, and the top cover 15 is installed on the protrusion by a threaded connection, and a sleeve 16 is detachably installed at the bottom of the top cover 15, and a ball 17 is movably connected to the arc surface on the bottom of the sleeve 16.

[0023] The first slider 5 and the second slider 25 move horizontally under the action of the screw transmission, and the guide column 6 on the moving frame 1 provides a guide groove for the movement of the first slider 5 and the second slider 25 to prevent the moving parts from deviating from their positions during the movement, thereby ensuring the stability of the device.

[0024] Specifically, the two ends of the first slider 5 are connected to the lifting block 8 through the first spring 9 and the first telescopic rod 7 respectively. The purpose of this arrangement is to ensure that the lifting block 8 can move up and down freely, and it can play a role of buffering and adjustment. The lifting block 8 can be returned to its original position during the movement, and the first telescopic rod 7 can play a role of guiding and adjusting the moving lifting block 8. The second telescopic rod 13 at one end of the lifting block 8 can, on the one hand, ensure the free horizontal movement of the lifting block 8 on the first slider 5, and on the other hand, effectively transmit the force of the lifting block 8 shaking up and down to the detection component 14.

[0025] A walking detection mechanism 2 is set up, and the handle on the mobile frame 1 is pushed to push the entire detection device to the corresponding position point of the steel template. After the first motor 3 is started, the first slider 5 drives the detection component 14 to move horizontally through the spiral transmission action, and then the horizontality detection work is performed on the steel template. When the X-axis direction of the horizontal surface of the steel template is uneven, the detection component 14 will move up and down under the elastic expansion and contraction of the first spring 9 and the up and down free movement of the first telescopic rod 7. At the same time, the position point generated by the marking pen 41 on the lifting block 8 during the drawing process on the drawing board 42 will effectively reflect the flatness of the steel template. In addition, the lifting The block 8 can drive the middle plate 18 to move up and down when it moves up and down. Since the middle plate 18 and the guide plate 19 are movably contacted and fitted, the gap between the middle plate 18 and the guide plate 19 is closed in the initial position. When the guide plate 19 is moved by the force, the friction pad 20 uses the friction resistance to fix the guide plate 19, and the fixed block 23 on the second spring 22 cooperates with the contact rod 21 to further fix the moved guide plate 19 at a corresponding height. By directly observing whether there is a gap between the middle plate 18 and the guide plate 19, it can be concluded whether the steel template is flat. It is convenient for personnel to operate and improves the detection accuracy.

[0026] Compared with directly detecting the flatness within a local area through rollers, if the Y-axis of the horizontal plane is uneven in the opposite direction, the lifting block 8 will not shake up and down when the rollers are directly used. At this time, the rollers will directly move stably on a higher horizontal plane without corresponding height difference shaking. However, the technical solution of the present invention rotates the ball 17 on the regional surface. Due to the small contact area, the ball 17 can be moved to various positions within the regional range through the rotating connection. If the height is inconsistent, the force will be immediately transmitted to the lifting block 8. Moreover, the rotation of the ball 17 on the arc surface in the sleeve 16 can effectively play a role of resistance and limit, preventing the ball 17 from separating from the sleeve 16.

[0027] refer to Figure 1 , Figure 2 , Figure 3 and Fig. 9 The detection component 14 includes an intermediate plate 18 fixed on the second telescopic rod 13, and the top and bottom of the intermediate plate 18 are movably abutted with guide plates 19, and the guide plate 19 is connected with a friction pad 20 along the height direction of the side wall of the mobile frame 1, and both ends of the guide plate 19 are integrally connected with a resistance rod 21, and the outside of the resistance rod 21 is placed on the side wall of the mobile frame 1. A second spring 22 is fixedly installed at one end of the second spring 22 with a fixed block 23 that is limitedly connected to the resistance rod 21.

[0028] The fixing block 23 is connected with an inclined surface on one side close to the middle plate 18, and the fixing block 23 is symmetrically arranged with respect to the center of the guide plate 19. The inclined surface arrangement on the fixing block 23 can make the guide plate 19 contact and connect with the inclined surface through the force during the approaching process, and move toward the side wall of the movable frame 1 under the elastic action of the second spring 22, so that the guide plate 19 is automatically connected with the other end of the inclined surface of the fixing block 23 in a limiting manner, so that the guide plate 19 can be fixed in the corresponding position. In order to return the guide plate 19 to the position in contact with the middle plate 18, it can be directly moved up and down by manual pulling, thereby facilitating the subsequent flatness detection work.

[0029] A ball assembly 12 is provided. When the second motor 10 is started, the turntable 11 can be driven to rotate. The rotation of the turntable 11 can drive the ball assembly to rotate together. Since the second motor 10 is fixed on the lifting block 8, when the ball 17 rotates, the flatness of the horizontal plane in the area in the X-axis and Y-axis directions can be detected together. If the flatness of any horizontal plane at a position in the area is not good, the force can be transmitted to the lifting block 8 to make it shake up and down. The ball assembly 12 is movably connected to the ball 17 through the arc surface on the sleeve 16, and the top cover 15 is installed on the turntable 11 by a threaded connection. While ensuring the effective rotation of the ball 17 and preventing the sleeve 16 from falling off, it can also facilitate the detachable installation work between personnel, thereby improving work efficiency, effectively increasing the detection range, and avoiding the occurrence of missed detection areas.

[0030] refer to Figure 2 to Figure 8 A beam and slab prefabricated steel formwork flatness and walking detection device also includes a rotating cleaning mechanism 24, which includes a second slider 25 fixed on the first screw shaft 4, a strip plate 26 is installed on the outer wall of the second slider 25, a third slider 27 is movably connected at the center of the strip plate 26, and both ends of the bottom of the second slider 25 are slidably connected to movable plates 28, the third slider 27 and the protrusion of the turntable 11 are connected by a first swing rod 29, and the extended end of the bottom of the third slider 27 and the movable plate 28 are connected by a second swing rod 30.

[0031] A movable shaft 31 is rotatably connected to the movable plate 28, one end of the movable shaft 31 is connected to a cleaning brush 32 in an annular array, and the other end is connected to a first gear 33 through a tensioning belt 46. One end of the first gear 33 is fixed to the output shaft of the third motor 34, and the outer wall of the first gear 33 is meshed with a second gear 35 corresponding to the tensioning belt 46.

[0032] A rotating cleaning mechanism 24 is provided. After the third motor 34 is started, it can drive the rotation of the first gear 33. Under the gear meshing transmission action, in conjunction with the transmission connection of the tension belt 46, the cleaning brushes 32 on the movable plates 28 at both ends can be rotated and cleaned, thereby effectively removing the granular impurities in the front section of the steel template, and preventing the external granular impurities from affecting the flatness detection accuracy. At the same time, during the rotation of the turntable 11, the third slider 27 on the strip plate 26 can be driven to move forward and backward through the rotation action of the crank connecting rod, and then through the rotation connection action of the second swing rod 30, during the movement of the third slider 27 forward and backward, the movable plate 28 can be driven to move in the Y-axis direction of the horizontal plane in the opposite direction. Since the tension belt 46 is made of elastic material and has a certain elasticity, the movable plate 28 can still transmit power to the movable shaft 31 during the horizontal movement, and the movable plate 28 can move normally. During the rotation of the cleaning brush 32, the Y-axis movement in the horizontal plane direction can be performed at the same time, thereby effectively expanding the cleaning range and promoting the orderly progress of the detection work.

[0033] The outsides of the output shafts of the first gear 33, the second gear 35 and the third motor 34 are all placed in a cover 36 fixed on the second slider 25, and the movable plate 28 is connected to the limiting groove along the length direction of the second slider 25. Both ends of the first swing rod 29 are installed on the protrusion of the turntable 11 and the third slider 27 by a rotating connection. Both ends of the second swing rod 30 are installed on the third slider 27 and the movable plate 28 by a rotating connection. The second swing rods 30 are staggered up and down. The staggered connection arrangement can ensure that the second swing rods 30 do not interfere with each other during the activity, thereby improving the safety of the device.

[0034] refer to Figure 1 , Fig.10 and Fig.11 A panel is fixedly installed on the top of the lifting block 8, and a slot is opened on the panel. A second screw shaft 38 fixed on the turning handle 37 is installed at the slot. A fourth slider 39 is spirally driven on the second screw shaft 38. Both ends of the fourth slider 39 are clamped and connected with a marking pen 41 through an arc plate 40. A drawing board 42 fixed on the moving frame 1 is provided on one side of the marking pen 41.

[0035] The drawing board 42 is connected to the inner wall of the beam 43 by means of a snap-fitting fixation. One end of the beam 43 is fixed to the movable frame 1. A rectangular groove is connected to the top of the beam 43 in the length direction and a U-shaped rod 44 is movably connected thereto. One end of the U-shaped rod 44 is pressed against the outer wall of the drawing board 42. Positioning holes are provided on both sides of the bottom end of the drawing board 42 and are locked and fixed by adjusting bolts 45.

[0036] The spiral transmission parts of the first screw shaft 4 and the second screw shaft 38 have a self-locking effect, which can fix the corresponding first slider 5 and the fourth slider 39 at the corresponding positions. While the drawing board 42 is limitedly connected with the crossbeam 43, the resistance and limiting effect of the U-shaped rod 44 and the locking and fixing of the adjusting bolt 45 can be used to fix the drawing board 42 on all sides on the crossbeam 43, ensuring that the drawing board 42 can be effectively fixed on the crossbeam 43, so that the marking pen 41 can be used to draw lines, and the height direction of the drawing board 42 and the movable frame 1 can be adaptively provided with scale lines, and the flatness deviation data on the steel template can be directly observed through the corresponding digital display on the scale lines.
