Description

Technical Field

[0001] The invention relates to the technical field of concrete antifreeze-thaw technology, in particular to a cement-stabilized crushed stone antifreeze type mixing device based on winter construction and a control method thereof. Background Art

[0002] High-altitude mine tunnel engineering is a very challenging and complex project. Its construction needs to overcome problems such as low atmospheric pressure at high altitudes. At the same time, the complexity and reliability of mine tunnel construction are important to mine safety and economy.

[0003] Concrete has always been one of the commonly used building materials in high-altitude areas. However, due to the limitations of climatic conditions in high-altitude areas, traditional concrete is prone to insufficient frost resistance in low temperature environments. Therefore, it is necessary to improve the frost resistance of concrete.

[0004] In the existing concrete preparation, the antifreeze performance of the concrete is generally improved by adding additives such as retarders, water reducers, antifreeze agents, etc. However, due to the strong water absorption of antifreeze agents, when preparing concrete, as the aggregate cement and water are stirred, the antifreeze agents will adsorb water. Combined with the freezing effect of the low temperature environment, the concrete will stick together into blocks. Once the concrete is agglomerated, it is easy to clog the mixing tank without additional crushing function, resulting in a decrease in the antifreeze performance of the concrete.

[0025] The control method of cement-stabilized crushed stone antifreeze type mixture based on winter construction includes the following steps:

[0026] Step 1: Place cement, aggregate and other materials required for preparing concrete into a mixing barrel, mix antifreeze, water reducing agent and other additives with water, and add them into the storage tank;

[0027] Step 2: Under the action of the driving component, the fixed stirring blade is driven to rotate, and the stirring and crushing mechanism is driven to move through the speed control mechanism to drive the movable stirring blade to rotate, and under the action of the fixed stirring blade and the movable stirring blade, the material in the stirring barrel is stirred;

[0028] Step 3: The stirring assembly will also drive the limit plate to move through the conduction regulating mechanism.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can crush the agglomerated materials, and both the agglomeration phenomenon caused by the coagulation effect of the concrete itself and the freezing phenomenon in a low-temperature environment can be effectively curbed under the action of the stirring and crushing mechanism in the present invention. Combined with the basic function of stirring, it can be ensured that the concrete will not agglomerate due to the water absorption of the antifreeze during stirring. When the concrete needs to be stirred, the fixed stirring blades are driven to rotate under the action of the driving component to mix the materials in the mixing barrel. The driving component will also drive the stirring and crushing mechanism to move through the speed control mechanism to drive the movable stirring blades to rotate. The antifreeze is evenly present in the concrete due to the stirring effect, thereby improving the anti-coagulation effect of the concrete product. At the same time, the driving component will also drive the conduction and regulation mechanism to move, causing the limit plate to rotate. Since the fluidity of the material in the mixing barrel is poor at this time, the resistance to the limit plate increases. Therefore, under the action of the limit plate, the conduction and regulation mechanism is controlled to move, so that the solution in the storage tank is transported to the mixing barrel. As the solution is added, since the antifreeze has a strong water absorption, it will cause agglomeration in the mixing barrel. At this time, under the action of the stirring and crushing mechanism, the angle between the movable stirring blade and the fixed stirring blade is adjusted to crush the agglomerated material. As the mixing proceeds, the fluidity of the concrete increases, which reduces the resistance to the limit plate. Under the action of the conduction and regulation mechanism, the rate of solution addition is reduced until the concrete mixing is completed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0046] See also Figure 1 to Figure 11 In the embodiment of the present invention, a cement stabilized gravel antifreeze type mixing device based on winter construction includes: a truss 1, a mixing barrel 2, a storage tank 3, a driving component, a fixed stirring blade 8, a stirring and crushing mechanism, a movable stirring blade 23, a speed control mechanism, a conduction control mechanism, and a limit plate 29. In order to ensure that the concrete will not clump due to water absorption by the antifreeze agent during mixing, it is necessary to crush the agglomerated materials. Therefore, when it is necessary to mix the concrete, the fixed stirring blade 8 is driven to rotate under the action of the driving component to mix the materials in the mixing barrel 2. The driving component will also drive the stirring and crushing mechanism to move through the speed control mechanism to drive the movable stirring blade 23 to rotate. At the same time, the driving component will also drive the conduction control mechanism The structure moves, causing the limit plate 29 to rotate. Since the fluidity of the material in the mixing barrel 2 is poor at this time, the resistance of the limit plate 29 increases. Therefore, under the action of the limit plate 29, the conduction and regulation mechanism is controlled to move, so that the solution in the storage tank 3 is transported to the mixing barrel 2. With the addition of the solution, since the antifreeze has a strong water absorption, it will cause agglomeration in the mixing barrel 2. At this time, under the action of the stirring and crushing mechanism, the angle between the movable stirring blade 23 and the fixed stirring blade 8 is adjusted to crush the agglomerated material. As the mixing proceeds, the fluidity of the concrete increases, which reduces the resistance of the limit plate 29. Under the action of the conduction and regulation mechanism, the addition rate of the solution is reduced until the mixing of the concrete is completed.

[0047] The mixing and crushing mechanism in the present invention has dual functions. On the one hand, it plays a basic role in mixing and stirring. On the other hand, it can avoid the cohesion problem caused by the coagulation effect of the concrete itself by crushing. And the crushing method can also overcome the concrete agglomeration defect caused by freezing in a low temperature environment.

[0048] The antifreeze liquid is evenly dispersed in every part of the concrete under the action of stirring, improving the anti-freezing effect of the overall concrete product.

[0049] The details are as follows, including:

[0050] A truss 1, and a mixing barrel 2 mounted on the truss 1, wherein a material storage tank 3 is provided at the end of the mixing barrel 2;

[0051] Also includes:

[0052] See also Figure 1-Figure 3 , Figure 5 , a driving assembly is arranged on the mixing barrel 2, and the driving assembly is connected to a symmetrically arranged fixed mixing blade 8, and the driving assembly includes a transmission rod 5 rotatably mounted on the mixing barrel 2, and the transmission rod 5 is connected to the output shaft of the motor 4 mounted on the truss 1, and a No. 1 belt 6 is sleeved on the transmission rod 5; it also includes a rotating rod 7 rotatably mounted on the mixing barrel 2 and passing through the mixing barrel 2, the rotating rod 7 is rotatably connected to the No. 1 belt 6, and the rotating rod 7 is also fixedly connected to the fixed mixing blade 8.

[0053] In detail, when concrete needs to be stirred, in order to increase the freeze-thaw resistance of concrete, it is necessary to add additives such as retarders, water reducers, air entraining agents, antifreeze agents, etc. during the concrete stirring process. Therefore, during stirring, the solid raw materials such as cement and aggregates required for concrete preparation are added into the mixing barrel 2. At this time, the motor 4 works, driving the transmission rod 5 to rotate, thereby driving the rotating rod 7 to rotate through the No. 1 belt 6. The rotating rod 7 will also drive the fixed stirring blade 8 to move. Under the action of the fixed stirring blade 8, the concrete is mixed.

[0054] See also Figure 1-Figure 3 , Figure 5 , Figure 8 , Fig. 9, a stirring and crushing mechanism is arranged in the stirring barrel 2 and connected to the driving component, the stirring and crushing mechanism is connected with a symmetrically arranged movable stirring blade 23, the stirring and crushing mechanism includes a rotating sleeve 18 rotatably mounted on the stirring barrel 2 and sleeved on the rotating rod 7, the rotating sleeve 18 is provided with a first annular groove 1801, an inclined groove 1802, and a second annular groove 1803, the two ends of the inclined groove 1802 are respectively connected with the ends of the first annular groove 1801 and the second annular groove 1803, and an angle control component is provided on the rotating rod 7, wherein the angle control component includes a No. 1 spiral groove 19 opened on the rotating rod 7, a supporting sleeve 20 is movably mounted on the rotating rod 7, and a No. 1 protrusion 22 slidably connected to the No. 1 spiral groove 19 is provided on the inner wall of the supporting sleeve 20; and also includes a limit block 21 mounted on the supporting sleeve 20, and the limit block 21 is slidably connected to the first annular groove 1801, the inclined groove 1802, and the second annular groove 1803.

[0055] It should be noted that the inclined grooves 1802 are symmetrically arranged at the two ends of the second annular groove 1803, and the two ends of the first annular groove 1801 are connected to the other ends of the two inclined grooves 1802. In the initial state, the limit block 21 is located in the first annular groove 1801. Under the action of the limit block 21 and the first annular groove 1801, the distance between the support sleeve 20 and the rotating sleeve 18 is minimized. The No. 1 protrusion 22 is located at the end of the stroke of the No. 1 spiral groove 19 toward the rotating sleeve 18. In order to increase the antifreezing ability of concrete, it is necessary to add antifreeze, water reducing agent and other additives to the concrete. As the concrete is stirred, since the antifreeze has a strong water absorption, the concrete is stirred. During stirring, water will be absorbed and bonded to the concrete into blocks. In order to ensure better quality of concrete, the blocks of concrete need to be broken. Therefore, when the rotating rod 7 rotates, the fixed stirring blade 8 is driven to rotate. The rotating rod 7 also drives the No. 1 spiral groove 19 to move, and drives the support sleeve 20 and the limit block 21 to rotate through the No. 1 protrusion 22, thereby driving the movable stirring blade 23 to move. Since the movable stirring blade 23 will encounter resistance during movement, it is ensured that the position of the No. 1 protrusion 22 in the No. 1 spiral groove 19 will not change, and the angle between the movable stirring blade 23 and the fixed stirring blade 8 will not change. At the same time, under the action of the speed control mechanism, the rotating sleeve 1 is driven 8 rotates, thereby driving the first annular groove 1801, the inclined groove 1802 and the second annular groove 1803 to move. Since the rotation speed of the rotating sleeve 18 is slightly greater than the rotation speed of the rotating rod 7, the limit block 21 will slide along the trajectory of the first annular groove 1801. When the limit block 21 enters one of the inclined grooves 1802, the supporting sleeve 20 will move in the direction away from the rotating sleeve 18, so that the No. 1 protrusion 22 slides in the No. 1 spiral groove 19 and rotates a certain angle while moving away from the rotating sleeve 18. The supporting sleeve 20 will also drive the movable stirring blade 23 to rotate a certain angle, so that the angle between the movable stirring blade 23 and the fixed stirring blade 8 is reduced. When the limit block 21 moves into the second annular groove 1803, the swing angle of the movable stirring blade 23 is the largest. Under the action of the movable stirring blade 23 and the fixed stirring blade 8, the agglomerated material is crushed. When the limit block 21 moves into another inclined groove 1802, the No. 1 protrusion 22 moves toward the initial position of the No. 1 spiral groove 19, so that the movable stirring blade 23 moves toward the initial position. When the No. 1 protrusion 22 returns to the first annular groove 1801 again, the angle between the movable stirring blade 23 and the fixed stirring blade 8 returns to the initial state again. Repeat the above steps, so as to achieve the crushing of the agglomerated concrete by adjusting the angle between the movable stirring blade 23 and the fixed stirring blade 8.

[0056] See also Figure 1-Figure 7The truss 1 is provided with a speed control mechanism connected to the stirring and crushing mechanism and the driving assembly. The driving assembly can drive the stirring and crushing mechanism to move through the speed control mechanism, so as to drive the movable stirring blade 23 to rotate while adjusting the angle between the movable stirring blade 23 and the fixed stirring blade 8. The speed control mechanism includes a fixed cone disk 9 installed on the transmission rod 5, a movable sleeve 11 is movably installed on the transmission rod 5, and a movable cone disk 12 is arranged on the movable sleeve 11. The truss 1 is provided with a driven assembly connected to the movable sleeve 11 and the rotating sleeve 18 , wherein the driven assembly includes a plurality of slide grooves 10 which are respectively opened on the movable cone disc 12 and the fixed cone disc 9 and are equidistantly distributed on the circumference, a clamping column 13 is slidably installed in the slide groove 10, an arc plate 14 is arranged on the clamping column 13, a second belt 17 which is rotatably connected to the rotating sleeve 18 is sleeved on the arc plate 14, an adjustment structure connected to the movable sleeve 11 is arranged on the truss 1, and the above-mentioned adjustment structure includes a cylinder 15 installed on the truss 1, a movable plate 16 is arranged on the output end of the cylinder 15, and the movable plate 16 is rotatably connected to the movable sleeve 11.

[0057] Furthermore, in the concrete mixing process, water and additives need to be added to the aggregate and cement. As water is added, the water adsorbed by the antifreeze will gradually increase, resulting in an increase in the amount of agglomeration. Therefore, it is necessary to adjust the rotation speed of the rotating sleeve 18 to adjust the frequency of the change in the angle between the movable stirring blade 23 and the fixed stirring blade 8. In the initial state, the movable sleeve 11 is located at the end of the stroke away from the fixed cone 9, so that the distance between the fixed cone 9 and the movable cone 12 is increased, so that the clamping column 13 is located at the end of the stroke on one side of the slide 10, and the distance between the arc plates 14 is the smallest. The second belt 17 can be stretched or contracted to a certain extent. At this time, the second belt 17 is in a contracted state, and the first belt 6 and Under the action of the No. 2 belt 17, the rotation speed of the rotating sleeve 18 is slightly greater than the rotation speed of the rotating rod 7. When it is necessary to increase the crushing of the agglomerated materials, the cylinder 15 works and drives the movable sleeve 11 to move toward the fixed cone disk 9 through the movable plate 16, so that the distance between the movable cone disk 12 and the fixed cone disk 9 is reduced. Under the action of the slide groove 10, the clamping column 13 slides to increase the distance between the arc plates 14. The No. 2 belt 17 will be stretched, so that the rotation speed of the rotating sleeve 18 increases. Under the action of the first annular groove 1801, the inclined groove 1802 and the second annular groove 1803, the frequency of the reciprocating motion of the support sleeve 20 increases, thereby accelerating the crushing frequency of the agglomerated materials.

[0058] See also Figure 3 , Figure 5 , Figure 9-11, a conduction and regulation mechanism is arranged in the stirring barrel 2 and connected to the driving assembly and the storage tank 3. The conduction and regulation mechanism is connected to a limit plate 29. The conduction and regulation mechanism can be actuated when the limit plate 29 is subjected to resistance, so as to transport the solution in the storage tank 3 to the stirring barrel 2 through the driving assembly. The conduction and regulation mechanism includes a hollow tube 24 installed in the stirring barrel 2, and a guide tube 25 penetrating the stirring barrel 2 and connected to the storage tank 3 is connected to the hollow tube 24; and also includes a plurality of drainage grooves 701 and 702 arranged on the rotating rod 7 and distributed equidistantly around the circumference. The feed trough 30, the rotating rod 7 is provided with an elastic component that cooperates with the drainage groove 701, wherein the elastic component includes a No. 2 spiral groove 26 opened on the rotating rod 7, and the rotating rod 7 is provided with a follower sleeve 27 that passes through the hollow tube 24, the follower sleeve 27 is fixedly connected to the limit plate 29, and the inner wall of the follower sleeve 27 is provided with a No. 2 protrusion 28 that is slidably connected to the No. 2 spiral groove 26; it also includes a spring 32 that is sleeved on the rotating rod 7 and abuts against the follower sleeve 27, and the follower sleeve 27 is provided with a feeding trough 31 that cooperates with the feed trough 30.

[0059] Furthermore, water is added to the storage tank 3. Under the action of the guide tube 25, the water in the storage tank 3 is transported to the hollow tube 24. In the initial state, the spring 32 is in a compressed state, so that the follower sleeve 27 is located at the end of the stroke away from the hollow tube 24, so that the feeding trough 31 and the feeding trough 30 are in a separated state, and the water in the hollow tube 24 will not enter the rotating rod 7. The follower sleeve 27 will also control the No. 2 protrusion 28 to be located at the end of the stroke on the side of the No. 2 spiral groove 26. When the concrete needs to be mixed, at this time, the rotating rod 7 rotates and drives the No. 2 protrusion 28 to move through the No. 2 spiral groove 26, thereby driving the follower sleeve 27. Movement causes the limit plate 29 to stir the concrete. Since the fluidity of the concrete is poor at this time, the limit plate 29 is subject to the greatest resistance, causing relative displacement between the follower sleeve 27 and the rotating rod 7. The No. 2 protrusion 28 will slide along the No. 2 spiral groove 26 and drive the follower sleeve 27 to move, causing the spring 32 to be compressed. The follower sleeve 27 will also drive the feed trough 30 to move and connect with the feeding trough 31, so that the conduction between the feeding trough 31 and the feed trough 30 is maximized. At this time, the hollow tube 24 will enter the rotating rod 7 through the feed trough 30 and the feeding trough 31, and be transported to the mixing barrel 2 through the drainage trough 701.

[0060] Preferably, as the amount of water added increases, the fluidity of the concrete in the mixing barrel 2 will gradually increase, so that the resistance of the limit plate 29 will decrease. At this time, the spring 32 is elastically released and drives the follower sleeve 27 to move in a direction away from the hollow tube 24, and the conduction size between the feed trough 30 and the feeding trough 31 is reduced until the concrete mixing is completed. The resistance of the limit plate 29 is minimized, so that the feeding trough 31 and the feed trough 30 are separated again.

[0061] Finally, it should be added that an electric heating component is also provided in the storage tank 3, and the electric heating component includes but is not limited to an electric heating wire heating component and an electromagnetic heating component. The electric heating component can heat and keep the water in the storage tank 3 warm, ensuring that the water has an initial temperature when added to the aggregate, and can effectively resist the low temperature of the environment.

[0062] The control method of cement-stabilized crushed stone antifreeze type mixture based on winter construction includes the following steps:

[0063] Step 1: Place cement, aggregate and other materials required for preparing concrete into a mixing barrel 2, and mix additives such as antifreeze and water reducing agent with water, and then add them into a storage tank 3;

[0064] Step 2: Under the action of the driving component, the fixed stirring blade 8 is driven to rotate, and the stirring and crushing mechanism is driven to move through the speed control mechanism to drive the movable stirring blade 23 to rotate, and under the action of the fixed stirring blade 8 and the movable stirring blade 23, the material in the stirring barrel 2 is stirred;

[0065] Step 3: The stirring assembly will also drive the limit plate 29 to move through the conduction regulating mechanism. Since the fluidity of the material in the stirring barrel 2 is the smallest at this time, the limit plate 29 is subject to the greatest resistance, causing the conduction regulating mechanism to move, thereby transporting the water in the storage tank 3 to the stirring barrel 2;

[0066] Step 4: With the addition of water, the material will clump under the action of the antifreeze agent. Therefore, under the action of the stirring and crushing mechanism, the angle between the movable stirring blade 23 and the fixed stirring blade 8 is adjusted to crush the agglomerated material;

[0067] Step 5: With the addition of water, the fluidity of the material in the mixing barrel 2 increases, so that the resistance of the limit plate 29 decreases. Under the action of the conduction and regulation mechanism, the water delivery volume in the storage tank 3 decreases until the concrete mixing is completed.
