Description

Technical Field

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

[0002] In construction projects, slump refers to an important indicator of the fluidity and plasticity of concrete. Slump testing is a method used to measure the fluidity and plasticity of concrete to ensure that the quality of concrete meets the design requirements. Slump testing is usually carried out by applying standardized test methods, which include placing the concrete sample in a specific conical mold, then lifting the mold at a certain height to allow the concrete to flow freely, and determining its slump by measuring the height to which the concrete collapses in the mold.

[0003] The concrete slump detection device of the prior art is very easy to be deformed and damaged due to external squeezing when being carried, which greatly affects the measurement result when in use. Therefore, in the actual operation process of the prior art, when transporting after the test is completed, the slump cone needs to be packaged for transportation to prevent the slump cone from being damaged. However, it needs to be packaged after each use, which is time-consuming and labor-intensive and thus inconvenient to carry.

[0004] A Chinese patent for a portable concrete slump detection device (publication number CN212514588U) is proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: after the operator has detected the concrete, he rotates the two half covers to cover the slump cone, and then uses fasteners to fix the two half covers together. The operator holds the handle to conveniently carry the slump cone; when testing the concrete, the operator rotates the screw rod to make the two half cylinders approach each other and fit together to form a slump cone, then pours the concrete into the slump cone, and then rotates the screw rod in the opposite direction to make the two half cylinders move away from each other, and the slump of the concrete is measured, so that the detection of the concrete can be completed. However, the device has the following technical problems in actual application: first, in the actual detection process, there are certain requirements on the speed of lifting the collapse cone, and when the half-cylinders are moved away from each other by rotating the screw rod, there is a situation where the cylinder wall blocks the concrete, that is, it needs to be rotated a large number of times during the operation to make the half-cylinder move a small distance, and the cylinder wall will interfere with the normal collapse of the concrete and the structure of the following detection; in addition, the concrete is accumulated on the bottom plate after collapse, and is disturbed and affected by other structures during cleaning, which brings inconvenience to maintenance work and needs to be improved urgently. Utility Model Content

[0005] The utility model aims to provide a concrete slump detection device for construction engineering to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A concrete slump detection device for construction engineering comprises a box body; the top and bottom of the box body are both in communication with the external environment, a cover plate is hingedly connected to the top of the box body, a slump cone is arranged in the box body, and a linkage component is also provided on the box body, the linkage component is used to control the movement of the slump cone by flipping the cover plate; a bottom plate is hingedly connected to the bottom of the box body, latches are arranged on the bottom plate and the cover plate, lock buckles used in conjunction with the latches are arranged on the top and bottom of the box body, a handle is fixedly connected to one side of the box body, and a plurality of support frames are fixedly connected to the bottom of the box body.

[0008] By adopting the above technical scheme, a box-type structure detection device is provided to facilitate carrying and is suitable for concrete detection in various places; and a collapse cone is provided which is linked to the box structure, so that the collapse cone can be lifted up at the same time when the cover plate is opened, thereby eliminating the need to spend time taking out the collapse cone for detection. At the same time, the integrated design does not require the fixation of various components, which facilitates storage and avoids loss.

[0009] A further improvement of the technical solution of the utility model is that the linkage component includes a strip groove opened on one side of the box body, slide rails are symmetrically fixedly connected on both sides of the box body, sliders are slidably connected to the outer sides of the slide rails, a movable frame is fixedly connected between the two sliders, one side of the movable frame is fixedly connected to a mounting frame, one end of the mounting frame extends to the interior of the box body through the strip groove, the collapse cone is fixedly connected to the mounting frame, a linkage rod is hinged on one side of the slider, and the end of the linkage rod away from the slider is hinged to the cover plate.

[0010] By adopting the above technical solution, a linkage rod is set up so that the cover plate can drive the slider to slide upward through the linkage rod during the opening process, and at the same time drive the collapse cylinder upward through the movable frame and the mounting frame. When the cover plate is opened to a vertical state, the collapse cylinder just rises to the top. The whole opening process is controlled within - seconds, and the concrete begins to collapse after the collapse cylinder is lifted.

[0012] By adopting the above technical solution, it is convenient to measure an appropriate amount of concrete through the measuring bucket.

When the slump cylinder is filled with material, the flow rate of the concrete is controlled by controlling the degree of opening of the valve until the concrete completely flows into the slump cylinder.

[0013] The further improvement of the technical solution of the utility model is that a spring is sleeved on the outer side of the injection pipe, and the inner diameter of the collapse cylinder is slightly smaller than the outer diameter of the injection pipe.

[0014] By adopting the above technical solution, when the cover is closed, the bottom of the injection pipe can be matched with the top of the collapse cylinder. The injection pipe is flush with the top of the collapse cylinder and can extend slightly into the collapse cylinder to prevent the concrete from spilling when it flows downward.

[0015] A further improvement of the technical solution of the utility model is that a slide buckle is slidably connected between the inner walls of the strip groove, a laser pen is fixedly installed on the slide buckle, the irradiation direction of the laser pen is horizontally toward the inside of the box, and a scale is set on one side of the inner wall of the box.

The zero boundary scale where the laser is blocked and not blocked during the movement is the height after the concrete collapses.

[0017] A further improvement of the technical solution of the utility model is that a limiting rod is fixedly connected to the inner side of the box body, and the limiting rod is used to limit the bottom plate.

[0018] By adopting the above technical solution, when the bottom plate is closed, the upper part is in a horizontal state under the limitation of the limiting rod.

[0019] A further improvement of the technical solution of the utility model is that: limit blocks are arranged at the top and bottom ends of the slide rail.

[0020] The above technical solution is adopted to facilitate limiting the sliding range of the slider to limit the open state of the cover.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

By setting a detection device with a box-type structure, it is easy to carry and can be applied to concrete detection in various places; and a slump cone linked with the box structure is provided, so that the slump cone can be lifted up at the same time during the opening of the cover plate, so that there is no need to spend time taking out the slump cone for detection, and the integrated design does not need to fix the various components, which is convenient for storage and avoids loss; in addition, since the box-type design is not convenient for cleaning after the test, a bottom plate that can be easily opened is provided, so that the latch can be unlocked after the detection is completed, and the bottom plate can be directly opened for cleaning.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] Example 1

[0035] In this embodiment, a detection device with a box-type structure is provided to facilitate carrying and is applicable to concrete detection in various places; and a collapse cone 9 is provided which is linked to the box body 1 structure, so that the collapse cone 9 can be lifted up while the cover plate 3 is flipped open, thereby eliminating the need to take out the collapse cone 9 for detection, and the integrated design does not require fixing of the various components, thereby facilitating storage and avoiding loss; in addition, since the box-type design makes it inconvenient to clean up after the test, a bottom plate 2 that can be easily flipped open is provided, so that the latch 17 can be unlocked after the test, and the bottom plate 2 can be directly flipped open for cleaning.

[0036] Example 2

[0037] like Figure 2 and Figure 3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the linkage component includes a strip groove 7 opened on one side of the box body 1, the two sides of the box body 1 are symmetrically fixedly connected with slide rails 4, the outer sides of the slide rails 4 are slidably connected with sliders 5, a movable frame 6 is fixedly connected between the two sliders 5, one side of the movable frame 6 is fixedly connected with a mounting frame 8, one end of the mounting frame 8 extends to the interior of the box body 1 through the strip groove 7, the collapse cone 9 is fixedly connected to the mounting frame 8, a linkage rod 10 is hinged on one side of the slider 5, and the end of the linkage rod 10 away from the slider 5 is hinged to the cover plate 3.

[0038] In this embodiment, by setting a linkage rod 10, the cover plate 3 can drive the slider 5 to slide upward through the linkage rod 10 during the opening process, and at the same time drive the collapse cylinder 9 upward through the movable frame 6 and the mounting frame 8. When the cover plate 3 is opened to a vertical state, the collapse cylinder 9 just rises to the top. The whole opening process is controlled within 3-5 seconds, and the concrete begins to collapse after the collapse cylinder 9 is lifted.

[0039] Example 3

[0040] like Figure 4 and Figure 5As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, a material injection pipe 12 is slidably connected to one side of the cover plate 3, one end of the material injection pipe 12 extends to the other side of the cover plate 3 and is fixedly connected to a measuring bucket 14, a valve 20 is arranged inside the material injection pipe 12, and a limiting ring 13 is fixedly connected to the outside of the material injection pipe 12 and on both sides of the cover plate 3.

[0041] In this embodiment, it is convenient to measure an appropriate amount of concrete through the measuring bucket 14. The amount when the measuring bucket 14 is filled and leveled can just fill the slump cone 9. When concrete is added to the measuring bucket 14, the valve 20 is in a closed state. When the slump cone 9 is filled with material, the flow rate of the concrete is controlled by controlling the degree of opening of the valve 20 until the concrete completely flows into the slump cone 9.

[0042] Preferably, a spring 15 is sleeved on the outer side of the injection tube 12 , and the inner diameter of the slump cone 9 is slightly smaller than the outer diameter of the injection tube 12 .

[0043] In this embodiment, when the cover plate 3 is in the closed state, the bottom of the injection pipe 12 can be matched with the top of the collapse cylinder 9. The injection pipe 12 is flush with the top of the collapse cylinder 9 and can extend slightly into the collapse cylinder 9 so that the concrete will not spill out during the downward flow.

[0044] like Figure 4 and Figure 6 As shown, preferably, a slide buckle 21 is slidably connected between the inner walls of the strip groove 7, a laser pen 22 is fixedly mounted on the slide buckle 21, the irradiation direction of the laser pen 22 is horizontally toward the inside of the box body 1, and a scale 11 is provided on one side of the inner wall of the box body 1.

[0045] In this embodiment, by sliding the slider 21, the laser pen 22 is moved in the vertical direction, and the laser pen 22 is controlled to irradiate, and its irradiation direction is directly facing the scale 11. During the movement, the zero boundary scale 11 where the laser is blocked and not blocked is the height after the concrete collapses.

[0046] like Figure 2 and Figure 4 As shown, preferably, a limiting rod 16 is fixedly connected to the inner side of the box body 1 , and the limiting rod 16 is used to limit the bottom plate 2 .

[0047] In this embodiment, when the bottom plate 2 is closed, the upper portion is in a horizontal state due to the limitation of the limiting rod 16 .

[0048] like Figure 1 and Figure 2 As shown, preferably, limit blocks are provided at both the top and bottom ends of the slide rail 4.

[0049] In this embodiment, it is convenient to limit the sliding range of the slider 5 to limit the open state of the cover plate 3.

[0050] The following specifically describes the working principle of the concrete slump detection device for construction engineering.

[0051] like Figure 1-Figure 6 As shown, when the box body 1 is in a closed state, the cover plate 3 and the bottom plate 2 are connected and locked with the box body 1 by means of a latch 17, and the box body 1 can be carried directly by means of the carrying handle 19; during inspection, concrete is added to the measuring bucket 14, and the capacity of the measuring bucket 14 is the same as that of the slump cone 9, so that the amount when the measuring bucket 14 is filled and flattened can just fill the slump cone 9, and the valve 20 is in a closed state when concrete is added to the measuring bucket 14, and during the process of adding concrete, auxiliary vibration is performed with tools until the concrete fills the measuring bucket 14 and is flattened.

[0052] At this time, the valve 20 can be opened to allow the concrete to flow downward and flow into the slump cone 9. When the box body 1 is not unfolded, the bottom of the slump cone 9 is flush with the bottom of the inner wall of the box body 1. The box body 1 can be properly shaken during the inflow process. During the process, the flow rate of the concrete can be controlled by controlling the degree of opening of the valve 20, and the test can be started until the concrete completely flows into the slump cone 9.

[0053] The latch 17 on the cover plate 3 is unlocked and the cover plate 3 is opened. During the opening process, the slider 5 is driven to slide upward through the linkage rod 10, and the slump cone 9 is driven to move upward through the movable frame 6 and the mounting frame 8. When the cover plate 3 is opened to the vertical state, the slump cone 9 just rises to the top, and the whole opening process is controlled within 3-5 seconds; after the slump cone 9 is lifted, the concrete begins to collapse, and the height after collapse can be measured after it stops for a certain period of time until the concrete no longer collapses. The measuring method is to slide the slider 21 to make the laser pen 22 move in the vertical direction, and control the laser pen 22 to irradiate, and its irradiation direction is directly opposite to the scale 11. During the movement, the zero boundary scale 11 where the laser is blocked and not blocked is the height of the concrete after collapse, and the height before collapse is the height of the slump cone 9. The two height differences are the slump index of the concrete.

[0054] After the inspection is completed, the box body 1 is lifted and the latch 17 on the bottom plate 2 is unlocked. At this time, the bottom plate 2 will be opened, and the concrete on the bottom plate 2 can be easily cleaned, which greatly facilitates practical application.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
