Description

Technical Field

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

[0002] Concrete pouring is essential for construction projects. Before the concrete is poured, the slump of concrete will be measured. The existing measuring tools include slump bucket and slump scale. The top and bottom of the slump bucket are both open structures. The measurement method is to fill the slump bucket with concrete, smooth the concrete on the top, and place the slump scale next to the slump bucket. The construction worker lifts the slump bucket up, and another construction worker observes the slump height of the concrete with the naked eye through the slump scale. In the existing measurement method, there are two variable factors that affect the accuracy of the measurement. On the one hand, when the first construction worker lifts the slump bucket up, the speed and angle of the bucket will affect the slump height, causing measurement deviations; on the other hand, the slump scale is located next to the slump bucket. Another construction worker manually measures the slump height. Since the scale and the top of the concrete cannot be completely leveled, reading errors are prone to occur. These two factors lead to inaccurate measurement of concrete slump, affecting subsequent concrete pouring construction. Summary of the invention

[0003] The utility model provides a concrete slump measuring device, which solves the problem that the existing slump measuring method is not accurate enough.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] A concrete slump measuring device comprises a slump bucket, a transparent scale, a platform base and a vertical moving mechanism. The top and bottom of the slump bucket are both open structures. The platform base is provided with a bucket groove for accommodating the bottom edge of the slump bucket. The transparent scale is vertically fixed on the platform base. The bottom of the transparent scale is located within the range surrounded by the bucket groove. The top of the transparent scale can be flush with the top of the slump bucket. The vertical moving mechanism is connected to the slump bucket and can drive the slump bucket to move vertically relative to the platform base.

[0006] The vertical moving mechanism comprises a supporting frame and a connecting rod. The supporting frame is provided with a vertically movable transmission mechanism. One end of the connecting rod is connected to the transmission mechanism, and the other end of the connecting rod is fixed to the slump bucket.

[0007] In one embodiment, the transmission mechanism includes a guide rail and a moving block. The guide rail is laid along the vertical direction of the support frame. One end of the connecting rod is fixed to the moving block. The moving block can move at a uniform speed along the guide rail.

[0008] In another embodiment, the transmission mechanism includes a transmission member, an upper rotating shaft and a lower rotating shaft, wherein the upper rotating shaft is rotatably connected to the top of the support frame, and the lower rotating shaft is rotatably connected to the bottom of the support frame, and the transmission member is arranged around the outer sides of the upper rotating shaft and the lower rotating shaft, and a connecting rod fixing position is provided on the transmission member, and one end of the connecting rod is fixed to the connecting rod fixing position. Further, the transmission member is a hinge or a belt.

[0009] Furthermore, the vertical movement mechanism includes two connecting rods, and the connecting rods are fixedly connected to the side walls of the slump bucket.

[0010] Furthermore, the bottom of the support frame is fixed on the platform base, and the platform base is provided with a transmission switch, and the transmission switch is electrically connected to the transmission mechanism.

[0012] Furthermore, the scale value at the top of the transparent scale is 0, and the scale values ​​gradually increase toward the bottom thereof.

[0013] The beneficial effects of the utility model are:

[0014] The slump measuring device of the utility model comprises a transparent scale which is vertically fixed on a platform base and a vertical moving mechanism which can drive the slump bucket to move up and down. The slump is driven up and down by a mechanical mechanism, which can overcome the uncertainty of the speed and angle of the bucket when the bucket is lifted manually, and can also adjust the speed of the slump bucket moving up and down to avoid the error caused by the manual bucket lifting. On the other hand, the transparent scale passes through the bottom and the top of the slump. When the slump bucket is lifted, the concrete collapses, and the transparent scale is located in the middle of the concrete. The scale change, that is, the slump, can be directly read, so that the measurement is more accurate and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-Figure 4 As shown, a concrete slump measuring device comprises a slump bucket 1, a transparent scale 2, a platform base 3 and a vertical moving mechanism 4. The top and bottom of the slump bucket 1 are both open structures. The platform base 3 is provided with a bucket groove 31 for accommodating the bottom edge of the slump bucket 1. When the slump bucket 1 is placed on the platform base 3, the bucket groove 31 can limit the position of the slump bucket 1, so that the slump bucket 1 cannot move, thereby avoiding affecting subsequent measurements.

[0023] The transparent scale 2 is vertically fixed on the platform base 3, the bottom of the transparent scale 2 is located within the range surrounded by the barrel groove 31, and the top of the transparent scale 2 can be flush with the top of the slump barrel 1, which is equivalent to the bottom of the transparent scale 2 being flush with the bottom of the slump barrel 1. The top of the transparent scale 2 is flush with the top of the slump barrel. After the construction personnel fill the slump barrel 1 with concrete, the concrete on the top is smoothed. At this time, the transparent scale 2 is buried in the slump barrel 1 and the concrete. The top of the transparent scale 2 has a scale value. When the slump barrel 1 is lifted, the concrete collapses, and the scale is exposed on the top of the transparent scale 2. At this time, the distance between the height of the concrete after collapse and the scale value on the top of the transparent scale 2 is the collapse height of the concrete.

[0024] The vertical moving mechanism 4 is connected to the slump bucket 1 and can drive the slump bucket 1 to move vertically relative to the platform base 3. The vertical moving mechanism includes a support frame 41 and a connecting rod 42. The support frame 41 is provided with a vertically movable transmission mechanism, one end of the connecting rod 42 is connected to the transmission mechanism, and the other end of the connecting rod 42 is fixed to the slump bucket 1.

[0025] In one embodiment, the transmission mechanism includes a guide rail and a moving block, the guide rail is laid along the vertical direction of the support frame 41, one end of the connecting rod 42 is fixed to the moving block, and the moving block can perform uniform linear motion along the guide rail. The moving block drives the slump bucket 1 to perform uniform linear motion in the vertical direction, which can control the lifting speed of the slump bucket 1 and ensure its lifting angle, and avoid manual operation that causes the lifting speed and angle to deviate and affect the slump measurement.

[0026] In another embodiment, the transmission mechanism includes a transmission member, an upper rotating shaft and a lower rotating shaft, wherein the upper rotating shaft is rotatably connected to the top of the support frame 41, and the lower rotating shaft is rotatably connected to the bottom of the support frame 41. The transmission member is wound around the outer sides of the upper rotating shaft and the lower rotating shaft, and a connecting rod 42 fixing position is provided on the transmission member, and one end of the connecting rod 42 is fixed to the connecting rod fixing position. Among them, the transmission member can be a hinge or a belt. In this way, the connecting rod 42 is fixed to the connecting rod fixing position of the hinge or the belt, and the slump bucket 1 is driven to move in the vertical direction by the rotation of the hinge or the belt, and the lifting speed and angle of the slump bucket 1 can also be controlled. In addition, the vertical moving mechanism is not limited to the above-listed methods, and can be composed of other structures.

[0027] Furthermore, if Figure 1 As shown, the vertical moving mechanism includes two connecting rods 42 , and the two connecting rods 42 are fixedly connected to the side wall of the slump bucket 1 .

[0028] The bottom of the support frame 42 is fixed on the platform base 3. The platform base 3 is provided with a transmission switch 32. The transmission switch 32 is electrically connected to the transmission mechanism.

[0029] An LED light strip is provided inside the transparent scale 2. An LED light strip switch 33 is installed on the platform base 3, and the LED light strip switch 33 is electrically connected to the LED light strip. When measuring at night, the light emitted by the LED light strip can allow the measurement personnel to see the scale on the transparent scale 2 clearly.

[0030] It should be noted that the scale value at the top of the transparent scale 2 in this embodiment is 0, and the scale value gradually increases toward the bottom, so that construction workers can directly measure the slump.

[0031] Four base brackets 34 are provided at the bottom of the platform base 3. The level and stability of the platform base 3 can be maintained by adjusting the heights of the four base brackets 34 to prevent the concrete from being in a tilted state during measurement.

[0032] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
