Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a vibration and cooling device suitable for large-volume concrete pouring. Background Technology

[0002] During construction, air bubbles may form inside the concrete during the pouring process. These bubbles reduce the concrete's density, causing honeycomb-like defects on the surface, which in turn affects the concrete's strength and stability. To address this issue, construction workers typically perform vibration after pouring to remove the air bubbles. However, this is usually done on-site with a single vibrator, making it difficult to completely eliminate the bubbles. Furthermore, leveling the concrete surface after vibration is inefficient; and manual vibration can easily result in insufficient compaction due to inadequate vibration time.

[0003] When constructing large-volume concrete, it is also necessary to strictly control the pouring temperature of the concrete to prevent temperature cracks. The current conventional method is to add ice water during concrete mixing. However, this method cannot maintain the cooled concrete at a consistently low temperature, and the temperature is uncontrollable, which can adversely affect the concrete strength.

[0004] In summary, the problems that need to be solved by those skilled in the art are that there are many air bubbles inside the concrete, the vibration work is inefficient and cannot be leveled, and the temperature during concrete pouring is uncontrollable. Utility Model Content

This large-volume vibration and cooling device has a large vibration area and high efficiency. It can level the concrete surface while vibrating and reduce the internal temperature of the concrete within a reasonable range, reduce the temperature difference between the inside and outside, and reduce the risk of temperature cracks in the concrete.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A vibratory cooling device suitable for large-volume concrete pouring includes a vibratory rod, a flat plate, a cooling circulation system, a motor, and a fixing rod.

A cooling circulation system is arranged at the fixing rod and the flat plate, and the end of the fixing rod is connected to the motor. A rotating joint is provided at the connection between the flat plate and the fixing rod.

[0008] There are multiple vibrating rods, which are evenly distributed along the bottom edge of the entire plate.

[0009] Each vibrating rod contains a U-shaped heat-conducting copper tube and a vibrating element. Each vibrating rod has a cylindrical cavity with a sealed cover at the center of the top for placing the vibrating element. The vibrating element contains a vibration motor, and the sealed cover has an electrical outlet for connecting the motor wire to the vibration motor.

[0010] A cooling medium inlet is formed on one end of the U-shaped heat-conducting copper tube, and a cooling medium outlet is formed on the other end. Both ends are installed on the top of the vibrating rod. A U-shaped bottom is formed at the bottom of the U-shaped heat-conducting copper tube, and a certain gap is formed between the U-shaped bottom and the bottom of the vibrating rod. A temperature sensor is located at the center of the bottom of the vibrating rod. The cooling circulation system includes a refrigeration internal circulation device. A refrigeration internal circulation outlet conduit is arranged at the outlet of the refrigeration internal circulation device, and a refrigeration internal circulation inlet conduit is arranged at the inlet of the refrigeration internal circulation device.

[0011] The cooling internal circulation device is connected to the cooling medium inlet of a vibrating rod through the cooling internal circulation outlet conduit. The cooling medium outlet of the vibrating rod is connected in series with the cooling medium inlet of the adjacent vibrating rod through a circulation copper pipe. Finally, the cooling medium outlet of the remaining vibrating rod is connected to the cooling internal circulation device through the cooling internal circulation inlet conduit.

[0012] The refrigeration internal circulation device is located in the middle of the fixed rod, and both the refrigeration internal circulation outlet pipe and the refrigeration internal circulation inlet pipe are installed inside the fixed rod.

[0014] The entire plate is a flat, hollow cylindrical cavity.

[0015] The cooling circulation system also includes a cooling medium circulation tank. Both the cooling medium circulation tank and the circulation copper pipe are arranged inside the flat plate cavity. A circulation inlet pipe and a circulation outlet pipe are provided at the center of the top of the cooling medium circulation tank. Similar cooling medium circulation inlet holes and cooling medium circulation outlet holes are opened on the side. The refrigeration internal circulation outlet pipe passes through the circulation inlet pipe and exits through the cooling medium circulation outlet hole.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0045] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0046] like Figure 1-6As shown, a vibratory cooling device suitable for large-volume concrete pouring includes a vibratory rod 1, a flat plate 2, a cooling circulation system 3, a motor device 4, and a fixing rod 5. The vibratory rod is set on the bottom surface of the flat plate, and the center of the top surface of the flat plate is connected to the front end of the fixing rod. A cooling circulation system is arranged at the fixing rod and the flat plate, and the end of the fixing rod is connected to the motor device. A rotating joint 21 is provided at the connection between the flat plate and the fixing rod.

[0047] Multiple vibrating rods are provided, and the multiple vibrating rods are evenly distributed along the bottom edge of the entire flat plate. Each vibrating rod is equipped with a U-shaped heat-conducting copper pipe 11 and a vibrating element 12. Each vibrating rod has a cylindrical cavity 14 with a sealed cover at the center of the top for placing the vibrating element. The vibrating element is equipped with a vibration motor. The sealed cover has an electrical outlet for connecting the motor wire to the vibration motor.

[0048] Understandably, when the vibratory motor is powered on, the vibrating element vibrates within the sealed cavity, driving the vibrating rod to vibrate within the concrete. Due to the transmission of force, the slab also experiences a certain amount of vibration, resulting in a better leveling effect.

[0049] Optionally, since a rotary joint is provided at the connection between the plate and the fixing rod, the rotary joint can provide redundant space for the vibration of the plate and ensure that the operation of other components on the upper part of the fixing rod is not disturbed.

[0050] Understandably, the wires need to be allowed a certain amount of leeway. This leeway is adjusted according to the actual vibration requirements of the plate and vibrator to avoid interference between the internal wires when the plate vibrates.

[0051] The U-shaped heat-conducting copper tube has a cooling medium inlet 111 on one side and a cooling medium outlet 112 on the other side, with both ends installed on the top of the vibrating rod.

[0052] The bottom of the U-shaped heat-conducting copper pipe has a U-shaped bottom 113, and there is a certain gap between the U-shaped bottom and the bottom of the vibrating rod. The temperature sensor 13 is located at the center of the bottom of the vibrating rod. A temperature sensor is set at the gap of the U-shaped bottom of the vibrating rod to detect the concrete temperature at the rod.

[0053] Optionally, a temperature sensor can be installed at the bottom gap of the U-shaped vibrator to detect the concrete temperature at each vibrator. However, in actual operation, the concrete temperature difference at each vibrator is not significant, so it is sufficient to install a temperature sensor at only one vibrator to obtain the overall concrete temperature.

[0054] The cooling circulation system includes a refrigeration internal circulation device 31, a refrigeration internal circulation outlet conduit 311 is arranged at the outlet of the refrigeration internal circulation device, and a refrigeration internal circulation inlet conduit 312 is arranged at the inlet of the refrigeration internal circulation device.

[0055] The cooling internal circulation device is connected to the cooling medium inlet of a vibrating rod through the cooling internal circulation outlet conduit. The cooling medium outlet of the vibrating rod is connected in series with the cooling medium inlet of the adjacent vibrating rod through a circulation copper pipe. Finally, the cooling medium outlet of the remaining vibrating rod is connected to the cooling internal circulation device through the cooling internal circulation inlet conduit.

[0056] Understandably, the cooling medium flows out from the outlet of the refrigeration internal circulation device, flows into the U-shaped heat-conducting copper pipe inside the first vibrating rod body through the refrigeration internal circulation outlet conduit, that is, it flows in from the cooling medium inlet of the U-shaped heat-conducting copper pipe, flows out from the cooling medium outlet of the U-shaped heat-conducting copper pipe, and flows into the U-shaped heat-conducting copper pipe of the second vibrating rod body, the third vibrating rod body, ... the Nth vibrating rod body in sequence, and flows into the refrigeration internal circulation inlet conduit from the cooling medium outlet of the U-shaped heat-conducting copper pipe inside the last vibrating rod body, and then flows back into the inlet of the refrigeration internal circulation device.

[0057] The refrigeration internal circulation device is located in the middle of the fixed rod, and both the refrigeration internal circulation outlet pipe and the refrigeration internal circulation inlet pipe are installed inside the fixed rod.

[0058] The cooling circulation system also includes a display and control device 32 and a flow control knob 33, both of which are arranged on one side of the refrigeration internal circulation device; an LED temperature display screen 321, an LED vibration time display screen 322, an equipment switch 324, and a setting button 323 are integrated on the display and control device.

[0059] The equipment switch 323 controls the on / off state of the equipment. The temperature sensor 13 transmits the temperature of the concrete in contact with the vibrator 1 and displays it on the LED temperature display screen 321. The vibration time setting button 324 sets the single vibration time, and the vibration time is displayed in real time on the LED display screen 322. By strictly controlling the vibration time, the concrete can be ensured to be compacted. The flow rate control knob 33 can control the flow rate of the cooling medium to control the temperature of the vibrator 1 and thus the temperature of the concrete in contact with the vibrator 1.

[0060] The entire plate is a flat, hollow cylindrical cavity.

[0061] The cooling circulation system also includes a cooling medium circulation tank 35, and both the cooling medium circulation tank and the circulation copper pipe 34 are arranged inside the flat plate cavity.

[0062] A circulation inlet pipe 351 and a circulation outlet pipe 352 are provided at the center of the top of the cooling medium circulation tank. A similar cooling medium circulation inlet hole 353 and a cooling medium circulation outlet hole 354 are provided on the side. The refrigeration internal circulation outlet pipe passes through the circulation inlet pipe and exits through the cooling medium circulation outlet hole. The refrigeration internal circulation inlet pipe passes through the cooling medium circulation inlet hole and exits through the circulation outlet pipe.

[0063] Understandably, by setting up a cooling medium circulation tank for running through the inlet and outlet pipes of the internal refrigeration circulation, interference between the pipes can be avoided.

[0064] Understandably, the inlet and outlet pipes of the refrigeration internal circulation need to be lowered with a certain margin. The margin is adjusted according to the actual shaking requirements of the plate and the vibrating rod to avoid interference between the internal pipes when the plate vibrates; the U-shaped heat-conducting copper pipes are symmetrically installed on both sides along the top center.

[0065] The vibrating rod is made of copper.

[0066] The lower end of the fixed rod is fixedly connected to the handle 6.

[0067] The motor device 4 includes a wire 41 and a wire storage device 42. The motor device is connected to the end of the fixed rod via the wire, and the wire storage device is located on the left side of the motor device.

[0068] The spacing between adjacent vibrating rods is 100 mm.

[0069] In concrete construction, the size of coarse aggregate particles in concrete typically ranges from 5 mm to 40 mm. The specific particle size selection varies depending on the intended use of the concrete, strength requirements, and construction conditions. In some special cases, the maximum particle size of coarse aggregate can be larger, but it usually does not exceed 80 mm. Setting the spacing of the evenly distributed vibrator bars to 100 mm allows the vibrator bars to move freely in the concrete slurry during operation without being stuck by the coarse aggregate.

[0070] This utility model has the following beneficial effects:

[0071] 1. The feature of this utility model is that it is suitable for vibrating and compacting large-volume concrete. By setting multiple vibrating rods under the flat plate, the vibrating area is large and the efficiency is high. The concrete surface can be leveled at the same time as the vibration.

[0072] 2. By setting up a cooling circulation system, and arranging circulating copper pipes and U-shaped heat-conducting copper pipes in series, the internal temperature of the concrete can be reduced within a reasonable range, the temperature difference between the inside and outside can be reduced, and the risk of temperature cracks in the concrete can be reduced.

[0073] 3. By installing temperature sensors inside a vibrating rod, the temperature of the concrete in contact with the vibrating rod is transmitted and displayed on an LED temperature display screen. The flow rate of the cooling medium is controlled by a flow control knob to control the temperature of the vibrating rod.

[0074] 4. The spacing between adjacent vibrating rods is 100 mm, which ensures that the vibrating rods can move freely in the concrete slurry without being stuck by coarse aggregate.

[0075] 5. The vibration time can be set by setting the vibration time button 324 and the vibration time can be displayed in real time on the LED display screen 322. By strictly controlling the vibration time, the concrete can be ensured to be compacted.

[0076] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
