Description

Technical Field

[0001] This application relates to the technical field of concrete pouring equipment, and particularly relates to a concrete heating and pouring device. Background Art

[0002] In bridge construction, the pouring of prestressed concrete is a very crucial link. With the acceleration of the urbanization process and the improvement of technical levels, the number of bridge construction projects has increased rapidly, which has directly promoted the progress of prestressed concrete pouring technology and its extensive application in bridge construction. However, in cold regions or during winter construction, the low-temperature environment poses many challenges to concrete pouring, such as a slowdown in the hardening speed, hindered strength development, and even frost damage, affecting the project quality and construction progress.

[0003] To overcome the problems of hardening and strength development during concrete pouring in a low-temperature environment, the existing bridge construction industry usually adopts various means. For example, some construction units use methods such as laying electric blankets or setting up a hot water circulation system to heat the poured concrete, and there are also methods of setting up temporary insulation sheds to isolate the cold environment. In addition, there are some that use chemical additives to improve the fluidity and early strength of concrete in a low-temperature environment. These means can, to a certain extent, alleviate the hardening problem of concrete at low temperatures to ensure the smooth pouring of concrete under cold conditions.

[0004] However, the above methods are relatively cumbersome to operate and have low efficiency, with defects such as uneven heating, limited heat preservation effect, and high cost. Especially in cold regions, these measures often fail to meet the requirements of rapid and uniform heating and efficient heat preservation, and it is difficult to effectively ensure the normal hardening and strength development of concrete, hindering the smooth progress of project construction. Therefore, there is an urgent need for a technical solution that can better solve the problems of concrete heating and heat preservation in a low-temperature environment. Utility Model Content

Detailed implementation manners

[0024] The following will further describe the present application in detail Figures 1-4 in conjunction with the attached drawings.

[0025] An embodiment of the present application discloses a concrete heating and pouring device.

The inner tank body 23 is made of a heat-conducting material, and the heat-conducting material can be stainless steel material or copper material with good heat conduction. Both the feed inlet 21 and the discharge outlet 22 are communicated with the inner tank body 23. An interlayer 24 is arranged between the inner tank body 23 and the heating tank 2, and a heat exchange liquid is filled in the interlayer 24.

[0026] Referring to Figure 1 , a tank cover 211 is arranged at the feed inlet 21. The tank cover 211 is adapted to the feed inlet 21 and is used to close the feed inlet 21. Valves 221 are arranged at the discharge outlet 22 and are used to close the discharge outlet 22.

[0027] Referring to Figure 2 、 3, a heating module 3 for heating the heat exchange liquid is provided on the heating tank 2. The heating module 3 includes a heating tube 31 and an electric control system 32. The heating tube 31 can be made of stainless steel pipe and is internally provided with a heating wire. The heating tube 31 is fixedly installed inside the interlayer 24. The electric control system 32 is electrically connected to the heating tube 31 and is used to supply power to the heating tube 31. The electric control system 32 is electrically connected to a control panel 321, and the control panel 321 is fixedly arranged on the side wall of the heating tank 2.

[0028] Refer to Figure 3 , a temperature sensor 33 is arranged inside the interlayer 24. The temperature sensor 33 is electrically connected to the electric control system 32. The temperature sensor 33 can adopt a high-precision thermocouple and is used to monitor the temperature inside the inner tank body 23 in real time; by monitoring the temperature change in real time through the temperature sensor 33, the power of the heating tube 31 can be adjusted in time to maintain a constant heating temperature.

[0029] Refer to Figure 3 , a heat insulation cavity 25 is arranged inside the side wall of the heating tank 2. The heat insulation cavity 25 is filled with a heat preservation and insulation material 251. The heat preservation and insulation material 251 can adopt rock wool or polyurethane foam and has good heat preservation performance and low thermal conductivity. The design of the heat insulation cavity 25 makes the heat not lose too much, thereby improving the energy utilization efficiency; the selection of the heat preservation and insulation material 251 needs to be determined according to the specific working temperature and environmental conditions to ensure the stable operation of the device in a low-temperature environment.

[0030] Refer to Figure 2 、 4 , a stirring shaft 4 is rotatably arranged inside the inner tank body 23. A driving source for driving the stirring shaft 4 to rotate is provided on the heating tank 2. The driving source includes a servo motor 26. The servo motor 26 is fixedly arranged on the top of the heating tank 2.

The driving gear 261 meshes with the driven gear 41.

[0031] Refer to Figure 2 、 3, a sliding sleeve 42 is slidably sleeved on the stirring shaft 4 along the length direction of the stirring shaft 4. A plurality of stirring paddles 43 are fixedly arranged on the sliding sleeve 42, and the stirring paddles 43 are equidistantly distributed along the circumferential direction of the sliding sleeve 42. A driving member for driving the sliding sleeve 42 to slide is arranged on the stirring shaft 4. The driving member includes a servo cylinder 44. The servo cylinder 44 is fixedly arranged at the top position of the stirring shaft 4. A transmission rod 441 is fixedly arranged on the piston rod of the servo cylinder 44. The transmission rod 441 extends into the inner tank body 23 and is fixedly connected with the sliding sleeve 42. By rotating the stirring shaft 4 in the inner tank body 23 and stirring the concrete through a plurality of stirring paddles 43, the concrete can be evenly heated during the heating process, avoiding the performance degradation caused by local overheating or uneven heating, thereby improving the heating quality and pouring effect of the concrete. And by driving the sliding sleeve 42 to slide along the stirring shaft 4 through the driving member, the stirring paddles 43 can stir at different positions of the stirring shaft 4. The design of the sliding sleeve 42 makes the stirring effect more uniform, effectively solving the problem that the concrete is prone to caking or separation during the heating process.

[0032] Referring to Figure 2 , a plurality of baffles 27 are fixedly arranged in the inner tank body 23 and at the discharge port 22. A connecting sleeve is coaxially and rotatably arranged at the bottom of the stirring shaft 4. Each baffle 27 is fixedly connected with the connecting sleeve, and the baffles 27 are equidistantly distributed along the circumferential direction of the stirring shaft 4. Through each baffle 27, the fluidity of the concrete during discharging can be effectively improved, avoiding the vortex phenomenon of the concrete at the discharge port 22 position, ensuring the full mixing and uniform discharging of the concrete, and improving the quality and construction efficiency of the concrete.

[0033] Referring to Figure 2 , a scraping plate 45 is fixedly arranged on the stirring shaft 4. The scraping plate 45 is made of wear-resistant and high-temperature-resistant materials, such as polytetrafluoroethylene materials or stainless steel materials, and is matched with the inner side wall of the inner tank body 23. The scraping plate 45 is in contact with the inner side wall of the inner tank body 23. During the rotation of the stirring shaft 4, the scraping plate 45 is driven to rotate, scraping off the concrete adhering to the inner wall of the inner tank body 23, reducing the adhesion and curing of the concrete during the heating process, and improving the heating uniformity and fluidity of the concrete.

[0034] The implementation principle of a concrete heating and pouring device according to an embodiment of the present application is as follows: By arranging an inner tank body 23 in a heating tank 2, and arranging an interlayer 24 filled with a heat exchange liquid and a heating module 3 between the inner tank body 23 and the heating tank 2, uniform heating of the concrete in the inner tank body 23 is achieved. The inner tank body 23 is made of a heat-conducting material, which can effectively conduct heat, thereby ensuring the normal hardening and strength development of the concrete in a low-temperature environment, and solving the problems of cumbersome operation and uneven heating of the existing heating methods. At the same time, through the cooperation of an electric control system 32 and a temperature sensor 33, precise control of the heating temperature is achieved, improving the reliability and economy of the entire heating system.
