Description

Technical Field

[0001] This invention relates to the field of concrete production technology, and to a concrete production apparatus, particularly a high-temperature resistant and crack-resistant concrete production apparatus and method. Background Technology

[0002] Concrete is a commonly used material in building structures, with advantages including high strength, good ductility, and strong frost resistance. However, concrete is prone to cracking under high temperatures. To address this issue, current solutions often involve adding appropriate amounts of water, cementitious materials, and aggregates to the concrete mix design. This increases the concrete's ductility and plasticity, thereby improving its resistance to high-temperature cracking. Alternatively, the appropriate use of high-performance cementitious materials, such as silicate cement and high-performance concrete, can further enhance the concrete's resistance to high-temperature cracking. These materials possess high heat resistance and crack resistance, enabling them to maintain the strength and stability of concrete under high-temperature conditions.

[0003] Currently, in the production of high-temperature crack-resistant concrete, workers need to pour cement, aggregates, cementitious materials, and water into the mixing equipment for uniform mixing. However, most current mixing equipment lacks a feeding function, requiring workers to use tools to cut open cement bags, lift them, and pour the cement into the mixing equipment. Since cement accounts for a large proportion of concrete production, workers need to pour multiple bags of cement into the mixing equipment manually. This manual feeding not only increases the workload of workers but also reduces the production efficiency of high-temperature crack-resistant concrete. Furthermore, the existing mixing equipment easily generates dust around the equipment when pouring cement, and the existing equipment cannot effectively manage the dust, which affects the health of nearby workers. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a high-temperature resistant and crack-resistant concrete production device and method. This high-temperature resistant and crack-resistant concrete production device has a lifting and feeding function, which effectively reduces the labor burden of workers and improves the production efficiency of high-temperature resistant and crack-resistant concrete. The device also has a dust removal function, which can effectively treat the dust around the device and protect the surrounding workers.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A high-temperature resistant and crack-resistant concrete production device includes a mixing equipment body. A U-shaped mounting frame is installed below the mixing equipment body. A linkage structure is movably connected to the lower inner wall of the mounting frame. Lifting structures are provided on both the left and right sides of the mounting frame. A base plate is slidably connected to both the left and right surfaces of the mounting frame, and a cement bag placement plate is provided above the base plate. A tilting structure is provided on one side of the top of the base plate. A connecting plate is hinged to one side of the cement bag placement plate, and one side of the connecting plate is in contact with the surface of the mounting frame and slidably connected to the mounting frame. The connecting plate is hollow inside and contains a driving structure. A cutting blade is provided on one side of the top of the connecting plate. Fixing frames are provided on both the left and right sides of the mixing equipment body, and hydraulic rods are fixed to the front and rear sides of the top of the fixing frames. The bottom end of the output shaft of the hydraulic rod passes through the fixing frame and is bolted to a positioning column. A dust removal structure is provided at the rear of the mixing equipment body.

[0007] The lifting structure includes a fixed groove, a first threaded rod, and a lifting block. The fixed groove is formed on the left and right surfaces of the mounting frame. The first threaded rod is rotatably connected to the inside of the fixed groove. The lifting block is slidably connected to the inside of the fixed groove, and the first threaded rod passes through the lifting block and is threadedly connected to the lifting block. One side of the lifting block is fixedly connected to the base plate.

[0008] The above structure allows for adjustment of the position of the cement bag placement plates on both sides, thereby lifting the cement bags.

[0009] The threads on the first threaded rods on the left and right sides of the mounting bracket have different directions. The lifting block on the left side of the mounting bracket is located below the inner wall of the fixing groove, while the lifting block on the right side is located above the inner wall of the fixing groove.

[0010] With the above structure, when the left cement bag placement plate rises, the right cement bag placement plate will fall, allowing workers to continue feeding cement from the side while it is being poured.

[0011] The linkage structure includes a double-groove pulley, a motor, and a single-groove pulley. The double-groove pulley is rotatably connected to the top of the inner wall of the mounting frame. The motor is fixed above the double-groove pulley, and the bottom end of the motor output shaft is fixedly connected to the top of the double-groove pulley. The single-groove pulley is located below the inner wall of the fixed groove, and a first threaded rod passes through the single-groove pulley and is fixedly connected to it. The double-groove pulley is connected to the single-groove pulley via a belt.

[0012] The above structure allows for simultaneous control of the first threaded rods on both sides, enabling them to rotate synchronously.

[0013] Guide grooves are provided on both the front and rear sides of the inner wall of the fixed groove, and guide blocks are fixed on both the front and rear sides of the lifting block. One side of the guide block extends into the interior of the guide groove and slides in connection with the inner wall of the guide groove.

[0014] The above structure guides the lifting block, increasing the stability of the cement bag placement plate when it moves up and down.

[0015] The tilting structure includes an electric push rod, a chute, a slider, a limiting groove, and a limiting block. The electric push rod is fixed to one side of the top of the base plate. The chute is opened on one side of the bottom of the cement bag placement plate, and the slider is slidably connected inside the chute. The top of the output shaft of the electric push rod is hinged to the bottom of the slider. Limiting grooves are opened on both the front and rear sides of the inner wall of the chute. Limiting blocks are fixed on both the front and rear sides of the slider, and the limiting blocks are located inside the limiting grooves and slidably connected to the inner wall of the limiting grooves.

[0016] The above structure allows the cement bag placement plate to tilt, thus allowing the cement to be poured out.

[0017] The drive structure includes a reciprocating threaded rod, a movable block, a gear, a rack plate, and a through slot. The reciprocating threaded rod is rotatably connected to the inside of the connecting plate. The movable block is slidably connected to one side of the inner wall of the connecting plate, and the reciprocating threaded rod passes through the movable block and is threadedly connected to it. The gear is located on the front and rear sides of the connecting plate. A connecting shaft is fixed to one side of the gear and passes through the inside of the connecting plate, and is fixedly connected to the front and rear ends of the reciprocating threaded rod. The rack plate is fixed to the front and rear sides of the left and right sides of the mounting bracket, and the gear meshes with the rack plate. The through slot is opened on the top surface of the connecting plate, and the bottom of the cutting blade passes through the through slot and is fixedly connected to the top of the movable block.

[0018] The above structure allows for control of the cutting blade's back-and-forth movement, thereby cutting open one side of the cement bag.

[0019] The dust removal structure includes a recovery box, an air inlet pipe, a dust extraction hood, a filter screen, and an air pump. The recovery box is located at the rear of the mixing equipment body. The air inlet pipe is connected to the top of the recovery box. The dust extraction hood is located on the rear side above the mixing equipment body, and the other end of the air inlet pipe is connected to the dust extraction hood. The filter screen is fixed inside the recovery box. The air pump is connected to the lower back of the recovery box, and an exhaust pipe is connected to one side of the air pump.

[0020] The above structure can suck in dust around the mixing equipment, thereby protecting the surrounding workers.

[0021] The cement bag placement plate has grooves on both the front and back sides of its top, and the grooves correspond to the positions of the positioning posts above.

[0022] The above structure facilitates the insertion of the positioning column through the cement bag, enabling subsequent material pouring operations.

[0023] A method for producing high-temperature resistant and crack-resistant concrete, the method comprising the following steps:

[0024] A: When workers need to pour cement into the mixing equipment for concrete mixing, they place the cement bags on the surface of the cement bag placement plate, with one side of the cement bag above the connecting plate. After placement, workers can directly turn on the motor below. The motor's output shaft drives the double-groove pulley below to rotate, which in turn causes the single-groove pulleys on both sides to rotate simultaneously, thus rotating the first threaded rods on both sides. The lifting block on the left side drives the bottom plate on the left side to rise, and the cement bag placement plate lifts the cement bag. When the cement bag placement plate rises, the gear moves on the surface of the rack plate, causing the gear to drive the reciprocating threaded rod inside the connecting plate to rotate. The moving block then drives the cutting blade above to move back and forth in the front and back directions, and the cutting blade can directly cut one side of the cement bag.

[0025] B: When the height of the cement bag placement plate is higher than the top of the mixing equipment body, the operator opens the electric push rod below, causing the output shaft of the electric push rod to push the upper slider to move, thus tilting the cement bag placement plate. Cement from the cement bag can then be poured into the mixing equipment body through the cement bag placement plate. When the cement bag placement plate is tilted to the corresponding position, the upper hydraulic rod opens, causing the output shaft of the hydraulic rod to push out the lower positioning column, allowing the positioning column to penetrate the cement bag and fix the cement bag to the surface of the cement bag placement plate, preventing the cement bag from slipping off the surface of the cement bag placement plate. While the left cement bag placement plate rises and pours cement, the right cement bag placement plate will descend. During the pouring process, the operator can place another cement bag on top of the right cement bag placement plate. After the left cement bag is poured out, the operator controls the drive shaft of the motor to rotate, causing the left cement bag placement plate to descend again. When the left cement bag placement plate descends, the upper hydraulic rod will retract the positioning column. At this time, the right cement bag placement plate rises, and the above operation is repeated to continue pouring cement.

[0026] C: After the cement bag placement plate pours the cement from the cement bag into the mixing equipment, the operator can turn on the air pump at the rear, which allows the dust extraction hood to draw air into the air intake pipe. The cement dust generated above the mixing equipment is directly drawn into the recycling bin. The filter screen directly filters the air entering the recycling bin, causing the cement dust to fall onto the surface of the filter screen, while the air is directly drawn out by the air pump and discharged outdoors, thus protecting the surrounding workers. After the cement is poured in, the operator pours other cementitious materials, aggregates, and water into the mixing equipment, and then the mixing and production of high-temperature crack-resistant concrete can begin.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. This invention features a lifting and feeding function, enabling the device to lift and raise cement bags and pour the cement from the bags into the mixing device. Furthermore, the device can cut the cement bags during the lifting process. With dual workstations, the device allows workers to continue feeding materials while the cement is being poured, effectively reducing the workload of workers and improving the production efficiency of high-temperature resistant and crack-resistant concrete. The device also has a dust removal function, effectively controlling dust around the device and protecting nearby workers.

[0029] 2. The present invention, through the setting of the fixed groove, the first threaded rod and the lifting block, allows the lifting block to move up and down on the surface of the first threaded rod after the first threaded rod on both sides is rotated, thereby adjusting the position of the cement bag placement plate.

[0030] 3. The present invention, through the arrangement of reciprocating threaded rod, movable block, gear, rack plate and through groove, enables the gear to drive the reciprocating threaded rod inside the connecting plate to rotate during the rising process of the cement bag placing plate, thereby causing the cutting blade above to move back and forth to cut open one side of the cement bag, which facilitates the subsequent feeding work.

The interior of the connecting plate 7 is hollow, and a driving structure 10 is installed inside the connecting plate 7. A cutting blade 9 is installed on one side of the top of the connecting plate 7. Fixed... The device includes a frame 11, with hydraulic rods 12 fixed to the front and rear sides of the top of the frame 11.

This invention has a lifting and feeding function, which enables the device to lift and raise the cement bag and pour the cement in the cement bag into the mixing device. Moreover, the device can also cut the cement bag during the lifting process. The device has a dual-station design, which allows the operator to continue feeding the cement while it is being poured, effectively reducing the workload of the operator and improving the production efficiency of high-temperature crack-resistant concrete. The device also has a dust removal function, which can effectively treat the dust around the device and protect the surrounding operators.

[0042] The lifting structure 4 includes a fixed groove 41, a first threaded rod 42, and a lifting block 43. The fixed groove 41 is opened on the left and right surfaces of the mounting frame 2. The first threaded rod 42 is rotatably connected to the inside of the fixed groove 41. The lifting block 43 is slidably connected to the inside of the fixed groove 41, and the first threaded rod 42 passes through the lifting block 43 and is threadedly connected to the lifting block 43. One side of the lifting block 43 is fixedly connected to the base plate 5. When the first threaded rods 42 on both sides are rotated, the lifting block 43 can move up and down on the surface of the first threaded rod 42, thereby adjusting the position of the cement bag placement plate 6.

[0043] The threads on the first threaded rods 42 on the left and right sides of the mounting frame 2 are in different directions. The lifting block 43 on the left side of the mounting frame 2 is located below the inner wall of the fixing groove 41, while the lifting block 43 on the right side is above the inner wall of the fixing groove 41. When the lifting block 43 on the left side rises, the lifting block 43 on the right side will fall, so that when the cement bag placement plate 6 on the left side is emptying the cement from the cement bag, the worker can place another cement bag on top of the cement bag placement plate 6 on the right side, waiting for the subsequent material loading work.

[0044] The linkage structure 3 includes a double-groove pulley 31, a motor 32, and a single-groove pulley 33.

The single-groove pulley 33 is located below the inner wall of the fixed groove 41, and the first threaded rod 42 passes through the single-groove pulley 33 and is fixedly connected to it. The double-groove pulley 31 is connected to the single-groove pulley 33 by a belt. When the motor 32 is turned on, the first threaded rods 42 on both sides can rotate simultaneously, thereby adjusting the position of the cement bag placement plates 6 on both sides.

[0045] Guide grooves 15 are provided on both the front and rear sides of the inner wall of the fixed groove 41. Guide blocks 16 are fixed on both the front and rear sides of the lifting block 43. One side of the guide block 16 extends into the interior of the guide groove 15 and slides in connection with the inner wall of the guide groove 15. When the lifting block 43 moves up and down inside the fixed groove 41, the guide blocks 16 on both sides can guide the lifting block 43, thereby improving the stability of the cement bag placement plate 6 when it moves up and down.

[0046] The tilting structure 8 includes an electric push rod 81, a chute 82, a slider 83, a limiting groove 84, and a limiting block 85. The electric push rod 81 is fixed to one side of the top of the base plate 5. The chute 82 is opened on one side of the bottom of the cement bag placement plate 6, and the slider 83 is slidably connected inside the chute 82. The top of the output shaft of the electric push rod 81 is hinged to the bottom of the slider 83. Limiting grooves 84 are opened on both the front and rear sides of the inner wall of the chute 82. Limiting blocks 85 are fixed on both the front and rear sides of the slider 83, and the limiting blocks 85 are located inside the limiting grooves 84 and are slidably connected to the inner wall of the limiting grooves 84. After the output shaft of the electric push rod 81 is pushed out, the cement bag placement plate 6 above can tilt as a whole, so that the cement in the cement bag above the cement bag placement plate 6 falls into the interior of the mixing equipment body 1, and the cement is automatically fed.

[0047] The drive structure 10 includes a reciprocating threaded rod 101, a movable block 102, a gear 103, a rack plate 104, and a through groove 105.

The movable block 102 is slidably connected to one side of the inner wall of the connecting plate 7, and the reciprocating threaded rod 101 passes through the movable block 102 and is threadedly connected to the movable block 102. The gear 103 is arranged on the front and rear sides of the connecting plate 7. A connecting shaft is fixed to one side of the surface of the gear 103, and the connecting shaft passes through the inside of the connecting plate 7 and is connected to the reciprocating threaded rod 101. The front and rear ends are fixedly connected.

The through groove 105 is opened on the top surface of the connecting plate 7, and the bottom of the cutting blade 9 passes through the through groove 105 and is fixedly connected to the top of the movable block 102. During the process of the cement bag placing plate 6 rising, the gear 103 can drive the reciprocating threaded rod 101 inside the connecting plate 7 to rotate, thereby causing the cutting blade 9 above to move back and forth, cutting open one side of the cement bag to facilitate subsequent material loading.

[0048] The dust removal structure 14 includes a recycling bin 141, an air inlet pipe 142, a dust extraction hood 143, a filter screen 144, and an air pump 145. The recycling bin 141 is located at the rear of the mixing equipment body 1. The air inlet pipe 142 is connected to the top of the recycling bin 141. The dust extraction hood 143 is located on the rear side above the mixing equipment body 1, and the other end of the air inlet pipe 142 is connected to the dust extraction hood 143. The filter screen 144 is fixed inside the recycling bin 141. The air pump 145 is connected to the lower back of the recycling bin 141, and an exhaust pipe is connected to one side of the surface of the air pump 145. When feeding cement, the operator can turn on the air pump 145 at the rear, so that the dust extraction hood 143 can draw in the dust above the mixing equipment body 1 to remove dust around the mixing equipment body 1 and prevent dust from affecting the surrounding operators.

[0049] The cement bag placement plate 6 has grooves 17 on both the front and back sides of the top. The grooves 17 correspond to the positions of the upper positioning post 13. When the positioning post 13 is pushed out, the lower groove 17 allows the bottom of the positioning post 13 to penetrate the surface of the cement bag, so as to fix the cement bag on the cement bag placement plate 6.

[0050] A method for producing high-temperature resistant and crack-resistant concrete, the method comprising the following steps:

[0051] A: When the staff needs to pour cement into the mixing equipment body 1 for concrete mixing production, the staff places the cement bag on the surface of the cement bag placement plate 6, with one side of the cement bag above the connecting plate 7. After placement, the staff can directly turn on the motor 32 below. The output shaft of the motor 32 drives the double groove pulley 31 below to rotate. Through the belt, the single groove pulleys 33 on the left and right sides rotate simultaneously, thereby causing the first threaded rods 42 on both sides to rotate. The lifting block 43 on the left side drives the bottom plate 5 on the left side to rise, and the cement bag placement plate 6 will lift the cement bag. When the cement bag placement plate 6 rises, the gear 103 moves on the surface of the rack plate 104, causing the gear 103 to drive the reciprocating threaded rod 101 inside the connecting plate 7 to rotate. The moving block 102 will then drive the cutting blade 9 above to move back and forth in the front and back directions. The cutting blade 9 can directly cut one side of the cement bag.

[0052] B: When the height of the cement bag placement plate 6 is higher than the top of the mixing equipment body 1, the operator opens the lower electric push rod 81, causing the output shaft of the electric push rod 81 to push the upper slider 83 to move, thereby tilting the cement bag placement plate 6. Cement from the cement bag can then be poured into the mixing equipment body 1 through the cement bag placement plate 6. After the cement bag placement plate 6 is tilted to the appropriate position, the upper hydraulic rod 12 opens, causing the output shaft of the hydraulic rod 12 to push out the lower positioning post 13, allowing the positioning post 13 to penetrate the cement bag and thus fix the cement bag to the surface of the cement bag placement plate 6. To prevent cement bags from slipping off the surface of the cement bag placement plate 6, when the left cement bag placement plate 6 rises and pours the cement, the right cement bag placement plate 6 will descend. During the pouring process, the worker can place another cement bag on top of the right cement bag placement plate 6. After the left cement bag is poured out, the worker controls the drive shaft of the motor 32 to rotate, which causes the left cement bag placement plate 6 to descend again. When the left cement bag placement plate 6 descends, the upper hydraulic rod 12 will retract the positioning column 13. At this time, the right cement bag placement plate 6 rises, and the above operation is repeated to continue pouring the cement.

[0053] C: After the cement bag placement plate 6 pours the cement from the cement bag into the mixing equipment body 1, the operator can turn on the air pump 145 at the rear, so that the dust extraction hood 143 can draw air into the air inlet pipe 142. The cement dust generated above the mixing equipment body 1 is directly drawn into the recycling bin 141. The filter screen 144 will directly filter the air entering the recycling bin 141, so that the cement dust falls on the surface of the filter screen 144, while the air is directly drawn out by the air pump 145 and discharged to the outside, thus protecting the surrounding operators. After the cement is poured in, the operator pours other cementitious materials, aggregates and water into the mixing equipment body 1, and then the mixing and production of high temperature resistant and crack-resistant concrete can begin.
