Description

Technical Field

[0001] The utility model relates to the field of concrete measurement of building materials, and particularly relates to an air content measuring device for civil building materials concrete. Background Technique

[0002] An air content measuring instrument for concrete is used to measure the air content in the mixture. Concrete can be divided into two components, namely coarse aggregate and mortar. The size of the coarse aggregate has little direct impact on the air content. The introduced air bubbles are distributed in the fine particles of the concrete, that is, the mortar, and the performance of the whole concrete is determined by the performance of the mortar.

[0003] After retrieval, a utility model patent with the publication number of CN216956050U specifically discloses an air content measuring instrument for concrete, including a measuring bowl. A bowl cover is arranged at the top of the measuring bowl. A motor is fixedly connected to the bottom of the measuring bowl. The output end of the motor is fixedly connected to a rotating rod. A rotating sleeve is arranged at the top of the rotating rod. A stirring rod is fixedly connected to the top of the rotating sleeve. Stirring blades are fixedly connected to the surface of the stirring rod. Reinforcing plates are fixedly connected to the inside of the stirring blades. A protective cover is fixedly connected to the bottom of the measuring bowl. A structure for connecting the rotating sleeve and the rotating rod is arranged inside the rotating sleeve. The structure for connecting the rotating sleeve and the rotating rod includes a short groove opened inside the rotating sleeve. By setting the motor to start running, the motor stirs the mixture through the rotating rod, the rotating sleeve, the stirring rod and the stirring blades, solving the problem that the existing air content detection device cannot automatically stir the mixture and the detection is relatively troublesome.

[0004] In the above patent, the motor rotates to drive the stirring blades to stir the mixture, so as to achieve the effect of stirring the mixture during detection. However, during use, since the mixture needs to be placed in a placement tank and sealed by a tank cover, the existing fixing method of the tank cover and the placement tank is to use four groups of bolt fixing clamps for fixing. This fixing method first requires the bolts to be screwed one by one when fixing or disassembling, making it inconvenient during fixing. And because four or six groups of clamps are used for fixing, when the bolts are screwed, the tightening degree of each group of bolts needs to be almost the same. Otherwise, the tank cover and the upper part of the tank body will not fit tightly, affecting the sealing performance of the connection between the tank cover and the placement tank, causing internal gas leakage and affecting the gas measurement result of the device.

[0005] Therefore, it is very necessary to invent an air content measuring device for civil building materials concrete to solve the above problems. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a device for measuring the air content of concrete in civil building materials. By rotating the rotating cylinder and driving the gear to rotate through the toothed ring, multiple groups of nuts can slide along the screw simultaneously, achieving the effect that the tank cover can stably fit above the placement tank and squeeze the rubber ring, so as to solve the problems of inconvenient installation and disassembly of the tank cover and insufficiently tight fit in the prior art.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: A device for measuring the air content of concrete in civil building materials, including a placement tank for holding the concrete to be tested;

[0008] A sealing structure is arranged above the placement tank to ensure the sealing performance of the placement tank during testing.

[0009] Preferably, the placement tank includes: a connecting ring, and the connecting ring is installed on the outer edge above the placement tank.

[0010] Preferably, a tank cover is attached above the placement tank, and a pressure gauge is installed above the tank cover.

[0011] Preferably, the sealing structure includes: a screw, the screw is installed above the connecting ring, six groups of screws are installed above the connecting ring, through holes are opened above the tank cover, the through holes are connected through the screws, nuts are threadedly connected to the screws, and positioning rings are fixedly sleeved outside the nuts.

[0012] Preferably, a fixed cylinder is fixedly connected above the tank cover, an annular groove is opened on the inner wall of the fixed cylinder, the annular groove is slidably connected to the positioning ring, a gear is fixedly sleeved outside the nut, a fixed ring is fixedly sleeved outside the tank cover, a rotating cylinder is sleeved outside the tank cover, and an annular cavity is opened on the inner wall of the rotating cylinder, and the annular cavity is slidably connected to the fixed ring.

[0013] Preferably, a toothed ring is fixedly connected to the inner wall of the rotating cylinder, the toothed ring is meshed with the gear, a docking ring is fixedly connected below the tank cover, the docking ring is connected through the placement tank, and a rubber ring is sleeved on the docking ring, and the rubber ring is attached and connected between the placement tank and the tank cover.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model:

[0015] The rotating cylinder drives the toothed ring to rotate and simultaneously drives multiple sets of gears to rotate, causing the gears to drive the nuts to move along the screw rods. When the nuts rotate within the fixed cylinders, they will push the can lids towards the placement cans, and the docking rings will move into the placement cans. At the same time, the can lids and the placement cans will squeeze the rubber rings, and the closer they get, the better the sealing performance. Moreover, since this method drives the toothed ring by the rotating cylinder and simultaneously drives multiple sets of gears to rotate, the rotational positions of each set of nuts on the screw rods are the same, ensuring the tight fit between the can lids and the placement cans. Additionally, this method enables the rapid installation and disassembly of the can lids, improving convenience. Brief Description of the Drawings
