Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a concrete collapse detection device. Background Art

[0002] The collapse of concrete refers to the plasticization and pumpability of concrete. The factors that affect the collapse of concrete include grading changes, water content, weighing deviation of scales, dosage of admixtures and temperature. The current method for detecting the collapse of concrete is: use a trumpet-shaped collapse barrel with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm on a horizontal support plate, and fill it with concrete in three times. After each filling, use a tamping hammer to evenly hit the outer wall of the collapse barrel 25 times. After tamping, smooth it and pull up the collapse barrel. The concrete collapses due to its own weight. The collapse can be obtained by subtracting the height of the barrel from the height of the concrete after collapse.

[0003] However, in the prior art, the terrain of a general construction site is relatively complex, and some ground surfaces appear to be flat but are not actually level. When the collapse of concrete is detected on the construction site, the horizontal support plate on which the concrete collapse barrel is placed is in a tilted state, causing the collapsed concrete to have an inclination angle, making the final measurement result inaccurate; and concrete is heavy, and it is more physically demanding to clean up the collapsed concrete on the horizontal support plate after the measurement is completed.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model connects the forward and reverse motors to the external power supply and the control terminal. When the device needs to be used to measure the collapse of concrete, the device is placed on a horizontal ground. If there is no horizontal ground around, the handle can be pulled. The handle is forced to drive the connecting plate 1 connected to it to move. When the connecting plate 1 moves, it drives the toothed plate and two extended legs connected to it to move. The movement of the toothed plate drives the gear meshing with it to rotate. The rotation of the gear drives the toothed plate meshing with the other side surface to move in the opposite direction. The movement of the toothed plate on the other side drives the connecting plate 1 connected to it and the two extended legs to move in the opposite direction. At this time, the four threaded rods threadedly embedded at one end of the four extended legs can be driven to extend outward. After extending, the height of the corresponding threaded rod can be adjusted by rotating a single knob according to the uneven position of the road surface. It replaces the side support legs to support the device to make it horizontal. At the same time, the spirit level can be used to observe whether the device is in a horizontal state. At the same time, the extended support assembly is limited by T-slot one, limit block one and T-slot two to prevent it from detaching. After the device is adjusted to the horizontal, the concrete collapse test can be carried out. The height of the conical barrel is measured in advance using a measuring rod and a measuring ruler, and then the inner part of the conical barrel is filled with concrete three times. After each filling, a tamping hammer is used to evenly hit the outer wall of the collapse barrel 25 times. After tamping, it is smoothed and the collapse barrel is pulled up. The concrete collapses due to its own weight. At this time, the measuring rod and the measuring ruler are used to measure the height of the concrete after the collapse. The collapse degree can be obtained by subtracting the height of the concrete after the collapse from the barrel height. In this way, measurements can be made on more complex ground at the construction site to ensure that the final measurement results are accurate.

[0014] 2. According to the utility model, after the measurement is completed, the measuring rod is moved to the highest position and then rotated so that it is embedded in three grooves and fixed. Then, the forward and reverse motors are started through the control terminal. The rotation of the forward and reverse motors drives the two-way threaded rod connected thereto to rotate. The rotation of the two-way threaded rod drives the two threaded clamps connected thereto to move in the opposite direction. At the same time, a pair of two threaded clamps are limited by two grooves embedded in the limit bar. When the two threaded clamps move, they both drive the connecting plate 2 connected to the surface thereof. The two connecting plates 2 are forced to push upward, driving the two limit clamps connected thereto to rise. The rise of the two limit clamps drives the limit column embedded on the surface thereof and the connecting blocks 2 at both ends of the limit column to rise. At this time, since the two T-slots 5 opened on the second surface of the two connecting blocks are both sleeved on the surfaces of the two limiting grooves, the supporting plate is driven to rise together when it rises, and the two T-slots 5 are limited by the two limiting grooves, and the two T-slots 5 can slide along the two limiting grooves to prevent jamming, and since the height of one end of the supporting plate is fixed, it will gradually become an inclined posture when rising. After the inclination is completed, the construction personnel can use cleaning tools to easily remove the concrete on the surface of the supporting plate. After removal, the forward and reverse motors are reversed through the control terminal to make the supporting plate flat again, which solves the problem that the concrete is heavy and it is more physically demanding to clean up the collapsed concrete after the measurement is completed.

[0030] Specifically: the height of the conical barrel 703 is measured in advance using the measuring rod 605 and the measuring ruler 606, and then the conical barrel 703 is filled with concrete three times. After each filling, a tamping hammer is used to evenly hit the outer wall of the collapsed barrel 25 times. After tamping, it is leveled and the collapsed barrel is pulled up.

[0032] Specifically: by pulling the handle 209, the handle 209 is forced to drive the connecting plate 203 connected thereto to move. When the connecting plate 203 moves, the toothed plate 201 and the two extended legs 204 connected thereto are driven to move. The movement of the toothed plate 201 drives the gear 107 meshing with it to rotate. The rotation of the gear 107 drives the toothed plate 201 meshing on its other side surface to move in the opposite direction. The movement of the toothed plate 201 on the other side drives the connecting plate 203 connected thereto and the two extended legs 204 to move in the opposite direction. At this time, the four threaded rods 206 threadedly embedded at one end of the four extended legs 204 can be driven to extend outward. After extending out, according to the uneven position of the road surface on which it is placed, the single knob 208 can be rotated respectively to adjust the height of the corresponding threaded rod 206, so that it can replace the side support legs 102 to support the device to make it horizontal.

[0033] In one embodiment, the tilting and lifting assembly 3 includes two connecting blocks 301, one end of which is fixedly mounted with a forward and reverse motor 302, the output end of the forward and reverse motor 302 passes through the surface of one of the connecting blocks 301 and is connected to a bidirectional threaded rod 303, one end of the bidirectional threaded rod 303 is embedded in the surface of one side of the other connecting block 301 through a bearing, the bottoms of the two connecting blocks 301 on opposite sides are fixedly connected to a limiting strip 304, both ends of the surface of the bidirectional threaded rod 303 are threadedly sleeved with threaded clamps 305, the bottoms of the two threaded clamps 305 are provided with grooves 306, and the two The grooves 1 306 are sleeved on the surface of the limit strip 304, the tops of the two threaded clamps 305 are movably connected to the connecting plate 2 307 through a movable shaft, and a movable shaft 312 is movably embedded in the center of the surface of the two connecting plates 2 307, and the tops of the two connecting plates 2 307 are movably connected to the limit clamps 308 through the movable shaft, and the tops of the two limit clamps 308 are embedded with limit columns 309, and both ends of the limit columns 309 are movably sleeved with connecting blocks 2 310, and the tops of the two connecting blocks 2 310 are opened with T-slots 5 311, and the bottoms of the two connecting blocks 1 301 are fixedly installed on the top of the supporting base plate 1.

[0034] Specifically: by starting the forward and reverse motor 302, the forward and reverse motor 302 rotates to drive the two-way threaded rod 303 connected thereto to rotate, and the two-way threaded rod 303 rotates to drive the two threaded clamps 305 connected thereto to move to the opposite side. At the same time, the two grooves 1 306 are embedded in the limit bar 304 to limit the two threaded clamps 305. When the two threaded clamps 305 move, they both drive the connecting plate 2 307 connected to their surfaces. The two connecting plates 2 307 are forced to push upward, driving the two limiting clamps 308 connected thereto to rise. The two limiting clamps 308 rise and drive the limiting columns 306 embedded in their surfaces to move upward. 09 and the connecting blocks 2 310 at both ends of the limiting column 309 rise. At this time, since the two T-slots 5 311 opened on the surfaces of the two connecting blocks 2 310 are both sleeved on the surfaces of the two limiting slots 701, the supporting plate 7 is driven to rise together with it when it rises, and the two T-slots 5 311 are limited by the two limiting slots 701, and the two T-slots 5 311 can slide along the two limiting slots 701 to prevent jamming, and since the height of one end of the supporting plate 7 is fixed, it will gradually become an inclined posture when it rises. After the inclination is completed, the construction personnel can use cleaning tools to easily remove the concrete on the surface of the supporting plate 7.

[0035] In one embodiment, the two T-slots three 202 are both sleeved on the surfaces of the two T-slots one 103, the four T-slots four 205 are evenly divided into two groups, the two groups of T-slots four 205 are both sleeved on the surfaces of the two T-slots two 105, the two tooth plates 201 are both meshed on both sides of the surface of the gear 107, and the four support legs 102 are all located on the inner sides of the four threaded rods 206.

[0036] Specifically: by sleeveing ​​two T-slots three 202 on the surfaces of two T-slots one 103, the four T-slots four 205 are evenly divided into two groups, and the two groups of T-slots four 205 are sleeved on the surfaces of the two T-slots two 105, so as to limit them, and by meshing the two tooth plates 201 on both sides of the surface of the gear 107, the two tooth plates 201 can move synchronously.

[0038] Specifically: by movably sleeved the two T-slots 5 311 on the surfaces of the two limit grooves 701, the limit is achieved and the sliding is enabled; by movably fitting the bottom of the support plate 7 on the top of the four load-bearing blocks 4, the four load-bearing blocks 4 support the weight of the concrete instead of the support plate 7; by moving the measuring rod 605 inside the groove 2 602 and the groove 3 603, the measuring rod 605 can be fixed.

[0039] Working principle: connect the forward and reverse motors 302 to the external power supply and the control terminal. When the device needs to be used to measure the collapse of concrete, the device is placed on a horizontal ground. If there is no horizontal ground around, the handle 209 can be pulled. The handle 209 is forced to drive the connecting plate 203 connected thereto to move. When the connecting plate 203 moves, the toothed plate 201 connected thereto and the two extended legs 204 are driven to move. The movement of the toothed plate 201 drives the gear 107 meshing therewith to rotate. The rotation of the gear 107 drives the toothed plate 201 meshing on the other side surface thereof to move in the opposite direction. The movement of the toothed plate 201 on the other side drives the connecting plate 203 connected thereto and the two extended legs 204 to move in the opposite direction. At this time, the four threaded rods 206 threadedly embedded at one end of the four extended legs 204 can be driven to extend outward. After extending out, the height of the corresponding threaded rod 206 can be adjusted according to the uneven position of the road surface, so that it replaces the side support legs 10 2 to support the device to make it horizontal. At the same time, the level ruler 702 can be used to observe whether the device is in a horizontal state. At the same time, the extension support component 2 is limited by the T-slot 103, the limit block 104 and the T-slot 2 105 to prevent it from detaching. After the device is adjusted to the horizontal state, the concrete collapse degree can be detected. The height of the conical barrel 703 is measured in advance using the measuring rod 605 and the measuring ruler 606. Then, concrete is poured into the conical barrel 703 for three times. After each filling, a tamping hammer is used to evenly hit the outer wall of the collapse barrel for 25 times. After tamping, it is smoothed and the collapse barrel is pulled up. The concrete collapses due to its own weight. At this time, the measuring rod 605 and the measuring ruler 606 are used to measure the height of the collapsed concrete. The collapse degree can be obtained by subtracting the height of the concrete after the collapse from the barrel height. In this way, measurements can be made on a more complex ground at the construction site. When the concrete collapse degree is detected, it can be ensured that the horizontal support plate on which the concrete collapse barrel is placed is in a flat state, so that the final measurement result is accurate.After the measurement is completed, the measuring rod 605 is moved to the highest point and then rotated so that it is embedded in the groove three 603 and fixed. Then, the forward and reverse motors 302 are started through the control terminal. The rotation of the forward and reverse motors 302 drives the two-way threaded rod 303 connected thereto to rotate. The rotation of the two-way threaded rod 303 drives the two threaded clamps 305 connected thereto to move to the opposite side. At the same time, the two grooves one 306 embedded in the limit bar 304 limit the two threaded clamps 305. When the two threaded clamps 305 move, they both drive the connecting plate two 307 connected to their surfaces. The two connecting plates two 307 are forced to push upward, driving the two limiting clamps 308 connected thereto to rise. The two limiting clamps 308 rise and drive the limiting columns 309 embedded on their surfaces and the connecting blocks two 31 at both ends of the limiting columns 309 to rise. 0 rises, at this time, because the two T-slots 5 311 on the surfaces of the two connecting blocks 2 310 are both sleeved on the surfaces of the two limiting grooves 701, the supporting plate 7 is driven to rise together when it rises, and the two T-slots 5 311 are limited by the two limiting grooves 701, and the two T-slots 5 311 can slide along the two limiting grooves 701 to prevent jamming, and because the height of one end of the supporting plate 7 is fixed, it will gradually become an inclined posture when it rises. After the inclination is completed, the construction personnel can use cleaning tools to easily remove the concrete on the surface of the supporting plate 7. After removal, the forward and reverse motors 302 are reversed by the control terminal to make the supporting plate 7 flat again, which solves the problem that the concrete is heavy and it is more physically demanding to clean the collapsed concrete on the horizontal supporting plate after the measurement is completed. ;
