Description

Technical Field

[0001] The present invention relates to the technical field of concrete detection, and particularly relates to a concrete slump detection device. Background Art

[0002] Concrete slump detection is a process of evaluating the fluidity and plasticity of concrete by measuring the degree of slump or spreading under the action of its own weight. The slump is an important index to measure the workability of concrete, reflecting the water retention, fluidity and cohesiveness of concrete. Slump detection is crucial for ensuring the working performance of concrete. Appropriate slump can make the concrete easy to pour and vibrate, reduce air bubbles and voids, and improve the structural density.

[0003] A concrete slump detection device is disclosed in the Chinese invention patent with the publication number CN111521760B, which includes a cylinder body and a funnel, and also includes a workbench. A circle of slots is opened on the upper surface of the cylinder body. The cylinder body is arranged on the workbench. The cylinder body is a frustum with a hollow interior and openings at both the upper and lower ends. The cylinder body includes a first semi-cylinder and a second semi-cylinder that are symmetric about the axis of the cylinder body and equally divided. The tops of the first semi-cylinder and the second semi-cylinder are rotatably connected by a rotating shaft. The first semi-cylinder and the second semi-cylinder are respectively inserted with plug blocks through the slots. The opening formed by the upper ends of the two plug blocks is larger than the opening formed by the lower ends. Two vertical rods that are symmetric about the axis of the cylinder body are arranged on the workbench. A bidirectional screw is arranged between the two vertical rods. The two ends of the bidirectional screw are respectively rotatably connected to the vertical rods. The bidirectional screw is divided into a left-handed thread section and a right-handed thread section. The left-handed thread section and the right-handed thread section of the bidirectional screw are respectively threadedly connected with a first abutting block and a second abutting block for abutting against the plug blocks. A cross bar is vertically arranged on the vertical rod. A collar that is sleeved outside the rotating shaft and rotatably connected to the rotating shaft is arranged at one end of the cross bar away from the vertical rod.

[0004] In view of the above related technologies, the inventor believes that there are the following defects: The first semi-cylinder and the second semi-cylinder jointly enclose the cylinder body for concrete slump detection. During the opening process of the first semi-cylinder and the second semi-cylinder, the slumped concrete may enter the joint between the first semi-cylinder and the second semi-cylinder. After this part of the concrete solidifies, it affects the normal opening and closing of the first semi-cylinder and the second semi-cylinder, and further affects the subsequent concrete slump detection work. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a concrete slump detection device.

[0006] The above technical object of the present invention is achieved by the following technical solution: A concrete slump detection device, including a bottom plate and a slump cone arranged on the bottom plate. A guide rail is fixed on the top of the bottom plate. An activity seat is arranged above the bottom plate. A slide rail that is slidably matched with the guide rail is fixed at the bottom of the activity seat. A control component for controlling the reciprocating sliding of the activity seat along the length direction of the guide rail is arranged on the bottom plate. An activity plate is arranged on one side of the slump cone and above the activity seat. A lifting mechanism for driving the lifting of the activity plate is arranged on the activity seat. A connecting plate is fixed on the side of the activity plate close to the slump cone. An installation ring is fixedly sleeved on the outer wall of the slump cone near its upper end. A clamping component for clamping the installation ring is arranged on the connecting plate.

[0007] By adopting the above technical solution, when detecting the slump of concrete, the staff first need to place the slump cone on the bottom plate, then place a funnel on the top of the slump cone, and shovel the mixed concrete to be detected into the slump cone through the funnel. Add the concrete in three layers. After adding each layer, use a vibrating rod to compact the concrete and then add the next layer of concrete. Then use a vibrating rod to compact the concrete. After the third layer of concrete is added and compacted, remove the funnel and level the concrete on the top of the slump cone. Then use the clamping component to clamp the installation ring on the slump cone. The lifting of the activity plate can be controlled through the lifting mechanism until the slump cone is completely separated from the concrete. Then use the control component to control the reciprocating sliding of the activity seat along the length direction of the guide rail until it completely deviates from the concrete. Then control the slump cone to descend until it abuts against the bottom plate through the lifting mechanism. After the concrete freely slumps, use a length measuring tool such as a ruler to measure the distance between the top of the center of the concrete slump pile and the top of the slump cone, which is the slump of the concrete. This changes the situation in the traditional technology where a split slump cone is used, resulting in the concrete being easily contaminated by the slump cone and thus affecting the subsequent detection work.

[0008] Further, a rotating rod is rotatably installed at a position on the top of the connecting plate close to the slump cone. The clamping assembly includes a first clamping unit, a second clamping unit, and a clamping cylinder. The first clamping unit includes an upper central plate sleeved on the rotating rod and rotatably connected to the rotating rod, a first arc-shaped clamping strip integrally formed on one side of the upper central plate close to the axis of the slump cone, a first connecting rod integrally formed on the side of the upper central plate away from the first arc-shaped clamping strip, and a first connecting block fixed to the end of the first connecting rod away from the upper central plate. The second clamping unit includes a lower central plate sleeved on the rotating rod and rotatably connected to the rotating rod, a second arc-shaped clamping strip integrally formed on one side of the lower central plate close to the axis of the slump cone, a second connecting rod integrally formed on the side of the lower central plate away from the second arc-shaped clamping strip, and a second connecting block fixed to the end of the second connecting rod away from the lower central plate. The cylinder body of the clamping cylinder is hinged to one side of the second connecting block close to the first connecting block, and the end of the piston rod of the clamping cylinder is hinged to one side of the first connecting block close to the second connecting block. The sides of the second arc-shaped clamping strip and the first arc-shaped clamping strip close to each other are respectively clamped and matched with both sides of the mounting ring.

[0009] By adopting the above technical solution, when conducting the concrete slump test, the staff first need to place the slump cone on the bottom plate and keep the axis of the slump cone coincident with the axes of the second arc-shaped clamping strip and the first arc-shaped clamping strip. Subsequently, the above slump test is carried out. After the test is completed, the staff need to adjust the piston rod of the clamping cylinder so that the sides of the second arc-shaped clamping strip and the first arc-shaped clamping strip close to each other are respectively clamped and matched with both sides of the mounting ring, so that the staff can control the movable plate to rise through the lifting mechanism to continue the work of concrete slump test.

[0010] Further, the lifting mechanism includes a lifting component and a driving component. The lifting component includes a threaded rod rotatably installed on the top of the movable seat and a guide rod fixed to the top of the movable seat. The threaded rod passes through the movable plate and is in threaded connection, and the guide rod passes through the movable plate and is in sliding fit. The driving component includes a motor fixed to the top of the movable seat, a driving gear fixed to the output end of the motor, and a driven gear fixedly sleeved on the threaded rod and meshing with the driving gear.

[0011] By adopting the above technical solution, when the second arc-shaped clamping strip and the first arc-shaped clamping strip cooperate to clamp the mounting ring, the staff need to start the motor. After the motor works, it drives the driving gear to rotate, so that the driven gear meshing with the driving gear and the threaded rod fixed to the driven gear rotate. Since the threaded rod is in threaded connection with the movable plate and the guide rod is in sliding fit with the movable plate, the movable plate can rise, so that the mounting ring and the slump cone rise, so that the concrete slumps naturally under the action of gravity.

[0012] Furthermore, a stop block is fixedly sleeved on the threaded rod. When the bottom of the nut, which is threadedly connected between the movable plate and the threaded rod, abuts against the top of the stop block, the second arc-shaped clamping strip and the first arc-shaped clamping strip both correspond to the mounting ring. The position of the top of the second arc-shaped clamping strip away from the upper center plate is flush with the position of the top of the first arc-shaped clamping strip away from the lower center plate, and the position of the bottom of the second arc-shaped clamping strip away from the upper center plate is flush with the position of the bottom of the first arc-shaped clamping strip away from the lower center plate.

[0013] By adopting the above technical solution, the setting of the stop block enables the movable plate to stay at a height where the first arc-shaped clamping strip and the second arc-shaped clamping strip can cooperate to just clamp the mounting ring, so as to lift the slump cone later and make the concrete slump naturally under the action of gravity.

[0014] Furthermore, the control assembly includes a fixed block fixed to the top of the bottom plate and a control cylinder fixed to the side wall of the fixed block. A vertical plate fixed to the end of the piston rod of the control cylinder is fixed to the bottom of the movable seat.

[0015] By adopting the above technical solution, after the lifting mechanism controls the slump cone to be higher than the top of the naturally slumped concrete, the staff needs to adjust the control cylinder to make the piston rod of the control cylinder extend, so that the movable seat connected to the vertical plate moves along the length direction of the guide rail until the slump cone deviates from the naturally slumped concrete. Then, through the lifting mechanism, the bottom of the slump cone can be controlled to be flush with the top of the bottom plate and fall at the position of the bottom plate close to the slumped concrete. At this time, the staff can measure the distance between the center of the top of the slumped concrete and the top of the slump cone through a length measuring tool, which is the concrete slump.

[0016] Furthermore, a vertical rod is rotatably mounted on the top of the bottom plate. The upper end of the vertical rod is fixed with a top plate. A transverse plate slidably matched with the vertical rod is sleeved on the vertical rod. A vertical spring fixed between the top of the transverse plate and the bottom of the top plate is sleeved on the vertical rod. A fixing assembly for fixing the transverse plate is arranged on the vertical rod. A tamping assembly for tamping the concrete in the slump cone is movably mounted on the transverse plate.

[0017] Furthermore, an installation through hole is formed through the transverse plate. The distance between the axis of the installation through hole and the axis of the vertical rod is equal to the distance between the axis of the slump cone and the axis of the vertical rod. The tamping assembly includes an elastic rod fixed to the inner wall of the installation through hole, a central disk fixed to the end of the elastic rod away from the inner wall of the installation through hole and coaxially arranged with the installation through hole, a vibrating rod fixed to the bottom of the central disk, and a handle fixed to the top of the central disk. A plurality of elastic rods are provided and are evenly distributed about the axis of the central disk.

[0018] By adopting the above technical solution, after adding a layer of concrete into the slump cone, the worker rotates the cross plate, and then the vibrating rod can be located directly above the slump cone. At this time, pressing down the cross plate can make the lower end of the vibrating rod extend into the slump cone. The fixing component can be used to fix the cross plate. Holding the handle and pushing the vibrating rod can compact the concrete in the slump cone through the vibrating rod. The elastic rod is made of a rubber material with good elasticity (such as the material of a rubber band). The worker can swing the vibrating rod at will through the handle, so as to facilitate the vibration of the concrete in the slump cone.

[0019] Further, the fixing component includes a horizontal plate fixedly sleeved on the vertical rod, a vertical plate fixed on the top of the horizontal plate and located on one side of the vertical rod, a cross rod penetrating through the vertical plate and slidingly matched with the vertical plate, and a moving plate fixed to one end of the cross rod and located between the vertical plate and the vertical rod. The moving plate is arranged parallel to the vertical plate. The fixing component further includes a sleeve fixedly sleeved on the vertical rod at the bottom of the cross plate, a limiting rod fixed to the side wall of the moving plate close to the vertical rod, an end plate fixed to the end of the cross rod away from the vertical rod, and a transverse spring sleeved on the cross rod and fixed between the end plate and the vertical plate. There are four limiting rods which are distributed in a rectangular array. The upper and lower limiting rods respectively abut against the edge of the lower end of the sleeve, and the upper two limiting rods are respectively located on both sides of the sleeve.

[0020] By adopting the above technical solution, after the vibrating rod descends into the slump cone, the worker pulls the end plate, and then the four limiting rods can be aligned with the edge of the lower end of the sleeve and inserted, thereby restricting the vertical movement of the sleeve and the cross plate, so that the worker can use the vibrating rod through the handle and complete the vibration work of the concrete in the slump cone.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The present application changes the situation in the traditional technology where the use of a split slump cone causes the concrete to easily adhere to the slump cone, which in turn affects the subsequent detection work.

[0023] 2. In the present application, when detecting the slump of concrete, the worker first needs to place the slump cone on the bottom plate and keep the axis of the slump cone coincident with the axes of the second arc-shaped clamping strip and the first arc-shaped clamping strip. Subsequently, the above slump detection test is carried out. After the detection is completed, the worker needs to adjust the piston rod of the clamping cylinder so that the mutually approaching sides of the second arc-shaped clamping strip and the first arc-shaped clamping strip are respectively clamped and matched with both sides of the mounting ring, so that the worker can control the movable plate to rise through the lifting mechanism to continue to complete the work of detecting the slump of concrete.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-5As shown in the figure, an embodiment of the present application discloses a concrete slump detection device, which includes a bottom plate 1 and a slump cone 2 disposed on the bottom plate 1. A guide rail 11 is fixed to the top of the bottom plate 1. An activity seat 3 is arranged above the bottom plate 1. A slide rail 31 that is slidably engaged with the guide rail 11 is fixed to the bottom of the activity seat 3. A control component 4 is arranged on the bottom plate 1 to control the reciprocating sliding of the activity seat 3 along the length direction of the guide rail 11. A movable plate 5 is arranged above the activity seat 3 on one side of the slump cone 2. A lifting mechanism 6 for driving the lifting of the movable plate 5 is arranged on the activity seat 3. A connecting plate 51 is fixed to the side of the movable plate 5 close to the slump cone 2. A mounting ring 21 is fixedly sleeved on the outer wall of the slump cone 2 near its upper end. A clamping component 7 for clamping the mounting ring 21 is arranged on the connecting plate 51.

[0032] When performing concrete slump detection, the staff first need to place the slump cone 2 on the bottom plate 1. Subsequently, place a funnel on the top of the slump cone 2, and shovel the mixed concrete to be detected into the slump cone 2 through the funnel. Add the concrete in three layers. After adding each layer, use a vibrating rod 103 to compact the concrete and then add the next layer of concrete. Then use the vibrating rod 103 to compact the concrete again. After the third layer of concrete is added and compacted, remove the funnel, scrape the concrete on the top of the slump cone 2. Subsequently, use the clamping component 7 to clamp the mounting ring 21 on the slump cone 2. The lifting of the movable plate 5 can be controlled through the lifting mechanism 6. Until the slump cone 2 is completely separated from the concrete, use the control component 4 to control the reciprocating sliding of the activity seat 3 along the length direction of the guide rail 11 until it completely deviates from the concrete. Then control the slump cone 2 to descend until it abuts against the bottom plate 1 through the lifting mechanism 6. After the concrete freely slumps, use a length measuring tool such as a ruler to measure the distance between the top of the center of the concrete slump pile and the top of the slump cone 2, which is the slump of the concrete. This changes the situation in the traditional technology where a split slump cone 2 is used, resulting in the concrete being easily contaminated by the slump cone 2, which in turn affects the subsequent detection work.

[0033] A rotating rod 511 is rotatably installed at a position on the top of the connecting plate 51 close to the slump cone 2. The clamping assembly 7 includes a first clamping unit 71, a second clamping unit 72 and a clamping cylinder 73. The first clamping unit 71 includes an upper center plate 711 sleeved on the rotating rod 511 and rotatably connected to the rotating rod 511, a first arc-shaped clamping strip 712 integrally formed on one side of the upper center plate 711 close to the axis of the slump cone 2, a first connecting rod 713 integrally formed on the side of the upper center plate 711 away from the first arc-shaped clamping strip 712, and a first connecting block 714 fixed to the end of the first connecting rod 713 away from the upper center plate 711; the second clamping unit 72 includes a lower center plate 721 sleeved on the rotating rod 511 and rotatably connected to the rotating rod 511, a second arc-shaped clamping strip 722 integrally formed on one side of the lower center plate 721 close to the axis of the slump cone 2, a second connecting rod 723 integrally formed on the side of the lower center plate 721 away from the second arc-shaped clamping strip 722, and a second connecting block 724 fixed to the end of the second connecting rod 723 away from the lower center plate 721. The cylinder body of the clamping cylinder 73 is hinged to the side of the second connecting block 724 close to the first connecting block 714, and the end of the piston rod of the clamping cylinder 73 is hinged to the side of the first connecting block 714 close to the second connecting block 724. The sides of the second arc-shaped clamping strip 722 and the first arc-shaped clamping strip 712 close to each other are respectively clamped and matched with both sides of the mounting ring 21.

[0034] When conducting the concrete slump test, the staff first need to place the slump cone 2 on the bottom plate 1 and keep the axis of the slump cone 2 coincident with the axes of the second arc-shaped clamping strip 722 and the first arc-shaped clamping strip 712. Subsequently, the above-mentioned slump test is carried out. After the test is completed, the staff need to adjust the piston rod of the clamping cylinder 73 so that the sides of the second arc-shaped clamping strip 722 and the first arc-shaped clamping strip 712 close to each other are respectively clamped and matched with both sides of the mounting ring 21, so that the staff can control the lifting of the movable plate 5 through the lifting mechanism 6 to continue to complete the work of concrete slump test.

[0035] The lifting mechanism 6 includes a lifting component 61 and a driving component 62. The lifting component 61 includes a threaded rod 611 rotatably installed on the top of the movable seat 3 and a guide rod 612 fixed to the top of the movable seat 3. The threaded rod 611 penetrates through the movable plate 5 and is in threaded connection, and the guide rod 612 penetrates through the movable plate 5 and is in sliding fit. The driving component 62 includes a motor 621 fixed to the top of the movable seat 3, a driving gear 622 fixed to the output end of the motor 621, and a driven gear 623 fixed and sleeved on the threaded rod 611 and meshing with the driving gear 622.

[0036] After the second arc-shaped clamping strip 722 cooperates with the first arc-shaped clamping strip 712 to clamp the mounting ring 21, the staff needs to start the motor 621. After the motor 621 works, it drives the driving gear 622 to rotate, so as to make the driven gear 623 meshed with the driving gear 622 and the threaded rod 611 fixed to the driven gear 623 rotate. Since the threaded rod 611 is threadedly connected to the movable plate 5 and the guide rod 612 is slidably engaged with the movable plate 5, the movable plate 5 can rise, so that the mounting ring 21 and the slump cone 2 rise, so that the concrete naturally slumps under the action of gravity.

[0037] A stop block (not shown in the figure) is fixedly sleeved on the threaded rod 611. When the bottom of the nut of the threaded connection between the movable plate 5 and the threaded rod 611 abuts against the top of the stop block, both the second arc-shaped clamping strip 722 and the first arc-shaped clamping strip 712 correspond to the mounting ring 21. The position of the top of the second arc-shaped clamping strip 722 away from one side of the upper center plate 711 is flush with the position of the top of the first arc-shaped clamping strip 712 away from one side of the lower center plate 721, and the position of the bottom of the second arc-shaped clamping strip 722 away from one side of the upper center plate 711 is flush with the position of the bottom of the first arc-shaped clamping strip 712 away from one side of the lower center plate 721.

[0038] The setting of the stop block makes the movable plate 5 stay at a height that can make the first arc-shaped clamping strip 712 and the second arc-shaped clamping strip 722 cooperate to just clamp the mounting ring 21, so as to lift the slump cone 2 later and make the concrete naturally slump under the action of gravity.

[0039] The control assembly 4 includes a fixed block 41 fixed to the top of the bottom plate 1 and a control cylinder 42 fixed to the side wall of the fixed block 41. A vertical plate (not shown in the figure) fixed to the end of the piston rod of the control cylinder 42 is fixed to the bottom of the movable seat 3.

[0040] When the lifting mechanism 6 controls the slump cone 2 to be higher than the top of the naturally slumped concrete, the staff needs to adjust the control cylinder 42 to make the piston rod of the control cylinder 42 extend, so that the movable seat 3 connected to the vertical plate moves along the length direction of the guide rail 11 until the slump cone 2 deviates from the naturally slumped concrete. Then, through the lifting mechanism 6, the bottom of the slump cone 2 can be controlled to be flush with the top of the bottom plate 1 and fall on the position of the bottom plate 1 close to the slumped concrete. At this time, the staff can measure the distance between the center of the top of the slumped concrete and the top of the slump cone 2 through a length measuring tool, which is the concrete slump.

[0041] A vertical rod 8 is rotatably installed on the top of the bottom plate 1. The upper end of the vertical rod 8 is fixed with a top plate 81. A cross plate 82 that is slidably matched with the vertical rod 8 is sleeved on the vertical rod 8. A vertical spring 83 is sleeved on the vertical rod 8 and is fixed between the top of the cross plate 82 and the bottom of the top plate 81. A fixing component 9 for fixing the cross plate 82 is arranged on the vertical rod 8. A tamping component 10 for tamping the concrete in the slump cone 2 is movably installed on the cross plate 82.

[0042] An installation through hole 821 is penetrated through the cross plate 82. The distance between the axis of the installation through hole 821 and the axis of the vertical rod 8 is equal to the distance between the axis of the slump cone 2 and the axis of the vertical rod 8. The tamping component 10 includes an elastic rod 101 fixed to the inner wall of the installation through hole 821, a central disc 102 fixed to the end of the elastic rod 101 far from the inner wall of the installation through hole 821 and coaxially arranged with the installation through hole 821, a vibrating rod 103 fixed to the bottom of the central disc 102, and a handle 104 fixed to the top of the central disc 102. There are multiple elastic rods 101 and they are evenly distributed about the axis of the central disc 102.

[0043] After adding a layer of concrete into the slump cone 2, the worker rotates the cross plate 82, and then the vibrating rod 103 can be located directly above the slump cone 2. At this time, pressing down the cross plate 82 can make the lower end of the vibrating rod 103 extend into the slump cone 2. Using the fixing component 9, the cross plate 82 can be fixed. Holding the handle 104 and pushing the vibrating rod 103 can compact the concrete in the slump cone 2 through the vibrating rod 103. The elastic rod 101 is made of a rubber material with good elasticity (such as the material of a rubber band). The worker can swing the vibrating rod 103 at will through the handle 104, so as to facilitate vibrating the concrete in the slump cone 2.

[0044] The fixing component 9 includes a horizontal plate 91 fixedly sleeved on the vertical rod 8, a vertical plate 92 fixed to the top of the horizontal plate 91 and located on one side of the vertical rod 8, a cross bar 93 penetrated through the vertical plate 92 and slidably matched with the vertical plate 92, and a moving plate 94 fixed to one end of the cross bar 93 and located between the vertical plate 92 and the vertical rod 8. The moving plate 94 is arranged parallel to the vertical plate 92. The fixing component 9 further includes a sleeve 95 fixed to the bottom of the cross plate 82 and sleeved on the vertical rod 8, a limiting rod 96 fixed to the side wall of the moving plate 94 close to the vertical rod 8, an end plate 97 fixed to the end of the cross bar 93 far from the vertical rod 8, and a transverse spring 98 sleeved on the cross bar 93 and fixed between the end plate 97 and the vertical plate 92. There are four limiting rods 96 and they are distributed in a rectangular array. The upper and lower two limiting rods 96 respectively abut against the edges of the lower end of the sleeve 95, and the upper two limiting rods 96 are respectively located on both sides of the sleeve 95.

[0045] After the vibrating rod 103 descends into the slump cone 2, the staff member pulls the end plate 97, which enables the four limit rods 96 to align with and insert into the edge at the lower end of the sleeve 95, thereby restricting the vertical movement of the sleeve 95 and the cross plate 82, so that the staff member can use the vibrating rod 103 through the handle 104 and complete the vibration work on the concrete in the slump cone 2.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
