[0002] Concrete is used in the work of building construction projects. Among them, people will use a slump test cylinder to detect the slump of concrete. Among them, the slump refers to the workability of concrete. Specifically, it is to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The slump is measured by a quantitative index to measure its degree, and is used to judge whether the construction can proceed normally. Generally, the slump of concrete is detected manually.

Therefore, it is very necessary to propose a slump detection device for engineering detection to solve the above problems. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a slump detection device for engineering detection as shown in Figures 1-4 , which includes a bottom plate 1. A hopper is movably placed on the top of the bottom plate 1. A detection cylinder 2 is placed on the top of the bottom plate 1. The concrete is poured into the inside of the detection cylinder 2 in three steps through the hopper. Each step requires tamping. Finally, the detection cylinder 2 is pulled out, and the height of the concrete is measured with a ruler. Then, combined with the height of the detection cylinder 2, the slump of the concrete can be calculated by introducing the calculation formula.

[0025] However, considering that when the detection cylinder 2 is used for slump detection, after the concrete is poured and tamped, the detection cylinder 2 is manually pulled up vertically. During the pulling-up process, due to improper operation or contact with the concrete, it is impossible to ensure the vertical pulling of the detection cylinder 2, resulting in a large detection error. Therefore, in the present utility model, a gantry 5 is fixedly arranged at the top of the bottom plate 1, and a limiting component is installed between the detection cylinder 2 and the gantry 5. The limiting component includes a connecting plate 3. The connecting plate 3 is fixedly arranged on the outer side surface of the detection cylinder 2. There are two connecting plates 3, and the two connecting plates 3 are symmetrically arranged about the center line of the detection cylinder 2. A limiting hole that penetrates through both side surfaces of the connecting plate 3 is fixedly arranged inside the connecting plate 3. A plug rod 8 is slidably arranged inside the limiting hole. A lifting plate 7 is fixedly connected between one ends of the two plug rods 8 that extend out of the connecting plate 3. The lifting plate 7 is slidably connected with the gantry 5 through a power component;

[0026] Specifically, the two plug rods 8 are synchronously inserted into the two connecting plates 3 on the detection cylinder 2. After tamping, through the power component, the lifting plate 7 is driven to vertically displace upward, synchronously driving to ensure the vertical displacement of the plug rod 8 and the connecting plate 3, so as to ensure that the detection cylinder 2 will not shift and collide with the concrete during the vertical displacement of pulling up, solving the problem that in the traditional slump detection of the detection cylinder 2, after the concrete is poured and tamped, the detection cylinder 2 is manually pulled up vertically, and during the pulling-up process, due to improper operation or contact with the concrete, it is impossible to ensure the vertical pulling of the detection cylinder 2, resulting in a large detection error.

[0027] In order to limit the lifting trajectory of the lifting plate 7 and improve the stability of the lifting of the lifting plate 7, movable grooves 6 are respectively opened on the inner walls of both sides of the gantry 5. One end of the lifting plate 7 extends into the movable groove 6 and is in movable fit with the movable groove 6. Through the installation of the movable groove 6, the lifting plate 7 is prevented from shifting during the lifting displacement.

[0028] Furthermore, the power component includes a threaded cylinder 10 and a threaded rod 11. The threaded cylinder 10 is fixedly arranged in the middle of the lifting plate 7. The threaded cylinder 10 is in threaded connection with the threaded rod 11. The threaded rod 11 is rotatably connected with the gantry 5 through a bearing. One end of the threaded rod 11 that extends out of the top of the gantry 5 is fixedly connected with a handle 12. After rotating the handle 12, the threaded cylinder 10 and the lifting plate 7 are driven to synchronously displace up and down, so as to pull up or lower the detection cylinder 2, and there is no need for manual bending operation.

[0029] Further, a first magnet 4 is fixedly arranged at one end of the connecting plate 3 close to the lifting plate 7, and a second magnet 9 is fixedly arranged on the outer circle of the insertion rod 8. When the insertion rod 8 is inserted into the limiting hole, the first magnet 4 and the second magnet 9 are adsorbed and attached to each other. Through the installation of the first magnet 4 and the second magnet 9, the detection cylinder 2 is prevented from shaking and displacing during ramming or pulling out, the connection stability between the detection cylinder 2 and the insertion rod 8 is improved, and the disassembly and cleaning of the detection cylinder 2 are facilitated, thus improving the convenience of the device.

[0030] Considering that the detection cylinder 2 also needs to cooperate with other measuring tools and auxiliary tools, a placement rack 13 and a chassis 14 are fixedly arranged on one side of the gantry 5. The placement rack 13 is located in the middle of the side of the gantry 5, and the chassis 14 is located at the bottom of the side of the gantry 5. A ramming rod 15 is movably attached to the middle of the placement rack 13, a scale rod 16 is fixedly arranged on the top of the chassis 14, a cross ruler 17 is movably arranged on the outer circle of the scale rod 16, and a scale table is arranged on the outer circle of the scale rod 16. When the detection cylinder 2 is lifted, the cross ruler 17 is rotated and the position of the cross ruler 17 on the concrete is adjusted, and the height of the concrete is read through the scale table. In addition, the ramming rod 15 is placed through the placement rack 13. In summary, the device can facilitate the carrying of measuring tools and auxiliary tools and avoid the problem of forgetting to leave them behind.

[0031] Further, when the lifting plate 7 is at the bottommost part of the movable groove 6, the heights of the limiting hole and the insertion rod 8 are the same, which prevents the threaded cylinder 10 from detaching from the threaded rod 11.

[0032] Further, support feet 18 are fixedly arranged at the four corners of the bottom of the bottom plate 1, fixing blocks 19 are fixedly arranged at the four-corner edges of the bottom plate 1, a lead screw 20 is threadedly connected to the middle of the fixing block 19, a pulley 21 is rotatably arranged at the bottom of the lead screw 20, insertion holes are fixedly arranged on both the lead screw 20 and the fixing block 19, and a limiting rod 22 is movably connected between the two insertion holes. When using the device, the support feet 18 are the supporting members. When the device needs to be transported and displaced, the limiting rod 22 is removed, the lead screw 20 is rotated, and the pulley 21 is displaced downward, so as to replace the supporting method of the support feet 18, facilitating the transportation and displacement of the device, reducing the handling labor. In addition, after the pulley 21 is displaced downward in place, the limiting rod 22 is inserted in place to prevent the lead screw 20 from rotating by itself.
