Description

Technical Field

[0001] The invention belongs to the field of concrete test block production, in particular to a concrete test block production device. Background Art

[0002] Concrete test blocks are made of a mixture of water, cement, stone and fly ash. When producing concrete test blocks, the concrete test block production equipment first mixes the raw materials into concrete slurry, then injects the slurry into the forming mold, and finally uses the demoulding mechanism to demould the formed concrete test blocks to complete the production of concrete test blocks.

[0003] The prior art also proposes some solutions. For example, a patent application with publication number CN105479594B discloses concrete test block production equipment, including a bracket loading assembly, a bracket conveying assembly, a bracket handling assembly and a concrete pouring assembly. The application realizes continuous automation of concrete loading, mold conveying and concrete pouring, realizes fully automated production and improves production efficiency.

[0004] When the concrete test block is pushed out of the mold, if the adhesion between the concrete test block and the side wall or bottom plate of the mold is too large, the part with greater adhesion cannot be pushed down directly during the pushing process, which may cause damage. In addition, when the concrete slurry is injected into the mold, the injection process will cause more bubbles to be generated in the slurry. Even if the bubbles can be expelled by vibration later, it takes a long time to eliminate the bubbles by vibration.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. A concrete test block production device described in the present invention drives the lubricating liquid storage component to extract the lubricating liquid by moving the mold bottom plate upward, discharges the lubricating liquid by moving the mold bottom plate downward, partially injects the lubricating oil into the smearing component, and cooperates with the reciprocating component and the smearing component to smear the lubricating oil on the top surface of the mold bottom plate. In the process of continuous downward movement of the mold bottom plate, the side wall brushing component is cooperated to smear the lubricating oil on the four side walls of the passing test block mold. The lubricating oil is pre-smeared into the test block mold, which can make the formed concrete test block more easily demolded from the test block mold, and prevents the concrete test block from having a large adhesion to the side wall or bottom plate of the test block mold, which causes the part with large adhesion to be damaged during the pushing process when the formed concrete test block is directly pushed, thereby affecting the integrity of the concrete test block.

[0019] 2. A concrete test block production device described in the present invention divides the concrete slurry injected into the grouting head through a dividing trough and then flows into a bulk plate in a slurry discharge trough. The bulk plate can first break up the concrete slurry and then discharge it from the slurry discharge trough, which not only expands the discharge area of ​​the concrete slurry, but also slows down the outflow speed of the concrete slurry. The concrete slurry in a large area can better contact with the air and release the bubbles inside it into the air. The concrete slurry with a low flow rate can reduce turbulence and prevent excessive generation of new bubbles. In addition, the grouting head reciprocates above the mold bottom plate and evenly spreads the slurry on the mold bottom plate. The slurry is continuously stacked together and its height increases. At the same time, as the mold bottom plate moves downward, the increased slurry top is always kept within the range of the initial grouting position with the grouting head, so that the injected slurry always keeps a close distance with the grouting head. By reducing the distance between the grouting head and the slurry, it is prevented that when the slurry is injected, the surrounding air is drawn in due to the injected slurry being thrown from a higher place, resulting in the generation of bubbles.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 11 As shown, a concrete test block production device according to an embodiment of the present invention comprises a supporting shell 1, a test block mold 2 arranged on the top of the supporting shell 1, a grouting head 4 arranged on the top of the test block mold 2, and a concrete slurry box 3 arranged on one side of the supporting shell 1, a slurry guide pipe 5 is arranged on the top of the grouting head 4, one end of the slurry guide pipe 5 is connected to the bottom of the concrete slurry box 3, a demoulding component 7 is arranged at the bottom end of the inside of the test block mold 2, a lubricating liquid storage component 6 is arranged at the bottom end of the test block mold 2, a side wall brushing component 10 is arranged inside the demoulding component 7, a smearing component 9 is arranged on one side of the grouting head 4, and a reciprocating component 8 is arranged at one end of the grouting head 4.

[0035] When the concrete test block is pushed out of the mold, if the adhesion between the concrete test block and the side wall or bottom plate of the mold is too large, the part with greater adhesion cannot be pushed down directly during the pushing process, which may cause damage. In addition, when the concrete slurry is injected into the mold, the injection process may cause more bubbles to be generated in the slurry. Even if the bubbles can be expelled by vibration later, it takes a long time to expel the bubbles by vibration.

[0036] The demoulding assembly 7 is used to raise the bottom plate in the test block mold 2, and the concrete test block formed inside the test block mold 2 is pushed out by the bottom plate to perform demoulding operation. At the same time, the demoulding assembly 7 drives the lubricating liquid storage assembly 6 to extract lubricating oil. After that, the demoulding assembly 7 is used to lower the bottom plate in the test block mold 2, and the demoulding assembly 7 drives the lubricating liquid storage assembly 6 to push the lubricating oil into the smearing assembly 9 and the side wall brushing assembly 10. The demoulding assembly 7 drives the bottom plate in the test block mold 2 to move downward, injects part of the lubricating oil into the smearing assembly 9, and cooperates with the reciprocating assembly 8 and the smearing assembly 9 to lubricate the top surface of the bottom plate. The application of oil, in the process of the demoulding component 7 driving the bottom plate to continuously move downward, cooperate with the side wall brushing component 10 to apply lubricating oil to the four side walls of the test block mold 2 passing by, so that the four surfaces and the bottom surface of the test block mold 2 can be applied with lubricating oil. Applying lubricating oil to the test block mold 2 in advance can make it easier for the formed concrete test block to be demoulded from the test block mold 2, and prevent the concrete test block from having a large adhesion to the side wall or bottom plate of the test block mold 2, resulting in the direct pushing of the formed concrete test block, and the part with large adhesion is damaged during the pushing process, affecting the integrity of the concrete test block;

[0037] At the same time, after the demoulding component 7 drives the bottom plate to move down slightly, an electric control valve needs to be set between the concrete slurry box 3 and the grouting pipe 5, which is not shown in the figure. The concrete slurry is injected into the concrete slurry box 3. When the grouting operation is required, the electric control valve is started, and the slurry is introduced into the grouting head 4 through the grouting pipe 5. The concrete slurry is discharged into the test block mold 2 by the grouting head 4. In this process, the reciprocating component 8 is used to make the grouting head 4 reciprocate above the test block mold 2. The grouting head 4 can expand the concrete slurry over a large area and inject it into the test block mold 2. The reciprocating grouting head 4 can make the concrete slurry evenly distributed in the test block mold 2. In addition, when the concrete slurry is injected into the test block mold 2, the slurry The grouting heads 4 are evenly stacked on the bottom plate. When the concrete slurry is first injected, the distance between the bottom plate and the grouting head 4 is relatively close. When the bottom plate continues to move downward, the distance between the bottom plate and the grouting head 4 increases, but the injected slurry always maintains a relatively close distance to the grouting head 4. By reducing the distance between the grouting head 4 and the slurry, the problem of bubbles being generated due to the injection of the slurry from a higher place and the surrounding air being drawn in is prevented. Moreover, the larger cross-sectional area of ​​the grouting head 4 can reduce the flow rate of the concrete slurry, so that the concrete slurry has more time to contact with the air when discharged into the test block mold 2 to release the bubbles into the air. In addition, the low flow rate can reduce turbulence and prevent excessive generation of new bubbles.

[0038] like Figures 1 to 11 As shown, the demolding assembly 7 includes a mold base plate 75 arranged at the bottom end of the test block mold 2, a push column 74 is fixed at the middle position of the bottom of the mold base plate 75, the push column 74 protrudes from the bottom of the test block mold 2 and is fixed with an upper push plate 73, a screw rod 71 is longitudinally penetrated at one end of the upper push plate 73, the screw rod 71 is arranged on the inner side wall of the support shell 1, a motor 72 is installed on the top of the screw rod 71, and the rotating shaft of the motor 72 is connected to the screw rod 71.

[0039] The motor 72 is started to drive the screw 71 to rotate, and the screw 71 drives the upper push plate 73 to move upward to push the push column 74 to move upward, and the push column 74 pushes the mold bottom plate 75 upward. The mold bottom plate 75 continues to move upward inside the test block mold 2, so that the concrete test block formed in the test block mold 2 can be pushed out for demolding. The motor 72 drives the screw 71 to rotate in the opposite direction, and can cooperate with the upper push plate 73 and the push column 74 to drive the mold bottom plate 75 to move downward.

[0040] like Figures 1 to 11As shown, the lubricating liquid storage assembly 6 includes a storage box 61 fixed at the bottom of the test block mold 2, a connecting pipe 2 69 is provided at the bottom of the storage box 61, the connecting pipe 2 69 is connected to the interior of the storage box 61, a liquid extraction pipe 610 is installed on the connecting pipe 2 69, a pumping box 62 is fixed to the front of the storage box 61, the pumping box 62 is located on one side of the upper push plate 73, a one-way valve 1 64 is provided at the middle position of the bottom of the pumping box 62, the one-way valve 1 64 is connected to the interior of the pumping box 62, a pumping pipe 1 63 is installed on the one-way valve 1 64, a one-way valve 3 68 is provided at the front end of the one-way valve 1 64, the one-way valve 3 68 is connected to the interior of the pumping box 62, and the one-way valve 3 68 is connected to the one end of the liquid extraction pipe 610. The two ends are connected, a one-way valve 2 65 is provided at the rear end of the one-way valve 1 64, the one-way valve 2 65 is connected to the interior of the extraction box 62, an injection pipe 2 66 is provided on the one-way valve 2 65, a connecting pipe 1 67 is provided at the middle position of the bottom of the upper push plate 73, a liquid guide cavity 611 is opened at the middle position inside the upper push plate 73 and the push column 74, the liquid guide cavity 611 is connected to the connecting pipe 1 67, the lubricating liquid storage assembly 6 also includes a extraction piston 614 arranged at the bottom end of the storage box 61, a piston rod 613 is fixed at the middle position of the top of the extraction piston 614, the piston rod 613 protrudes from the top of the storage box 61 and is fixed with a push-pull plate 612, and the push-pull plate 612 is fixedly connected to the upper push plate 73.

[0041] The one-way design of the one-way valve 1 64 and the one-way valve 2 65 can only discharge the lubricating oil in the pumping box 62, and cannot allow the lubricating oil to enter the pumping box 62 through the one-way valve 1 64 and the one-way valve 2 65. The one-way design of the one-way valve 3 68 can only allow the lubricating oil to be injected into the pumping box 62, and cannot allow the lubricating oil to be discharged from the pumping box 62 through the one-way valve 3 68.

[0042] Inject the required lubricating oil into the storage box 61. When the upper push plate 73 pushes the mold bottom plate 75 to move upward, the upper push plate 73 drives the push-pull plate 612 to move upward. The push-pull plate 612 pulls up the piston rod 613 and the pumping piston 614 at its bottom. The pumping piston 614 pumps the lubricating oil in the storage box 61 into the pumping box 62 through the connecting pipe 2 69, the pumping pipe 610 and the one-way valve 3 68. When the top surface of the mold bottom plate 75 moves to a position on the same horizontal plane as the top of the test block mold 2, the pumping piston 614 moves to the top of the pumping box 62. After that, the upper push plate 73 drives the mold bottom plate 75 to move downward. The upper push plate 73 drives The push-pull plate 612 moves downward, and the push-pull plate 612 pushes down the pumping piston 614 through the piston rod 613, and the lubricating oil in the pumping box 62 is pushed out through the pumping piston 614, and part of the lubricating oil is injected into the smearing component 9 through the injection pipe 1 63 and the one-way valve 1 64, and the lubricating oil is applied to the top surface of the test block mold 2 in cooperation with the smearing component 9, and the other part of the lubricating oil is injected into the liquid guide cavity 611 through the one-way valve 2 65, the injection pipe 2 66 and the connecting pipe 1 67, and is injected into the side wall brushing component 10 through the liquid guide cavity 611, and the lubricating oil is applied to the four inner side walls of the test block mold 2 in cooperation with the side wall brushing component 10 and the downwardly moved mold bottom plate 75;

[0043] Applying lubricant to the test block mold 2 in advance can make it easier to demold the formed concrete test block from the test block mold 2, and prevent the concrete test block from having a strong adhesion to the side wall of the test block mold 2, which causes the part with strong adhesion to be damaged during the pushing process when the formed concrete test block is directly pushed, thus affecting the integrity of the concrete test block.

[0044] like Figures 1 to 11 As shown, the side wall brushing assembly 10 includes an oil groove 101 opened at the middle position inside the mold bottom plate 75, the oil groove 101 is connected to the liquid guide cavity 611, the outer wall of the mold bottom plate 75 is opened with a groove 103, the side wall of the oil groove 101 is opened with an oil flow hole 102, the side wall of the groove 103 is fixed with bristles 104, and the bristles 104 are located around the oil flow hole 102.

[0045] The lubricating oil is injected into the liquid guiding cavity 611 through the one-way valve 2 65 , the injection pipe 2 66 and the connecting pipe 1 67 , and then injected into the oil groove 101 through the liquid guiding cavity 611 . The lubricating oil in the oil groove 101 will be discharged to the grooves 103 around the mold bottom plate 75 through the oil flow holes 102 . Each oil flow hole 102 located on the groove 103 is provided with bristles 104 around it. The downwardly moved mold bottom plate 75 cooperates with the bristles 104 to apply the lubricating oil to the four inner side walls of the test block mold 2 passing through. When the mold bottom plate 75 moves down to the bottommost end of the test block mold 2 , the lubricating oil is completely applied to the four inner side walls of the test block mold 2 . The application of lubricating oil to the side walls of the test block mold 2 can prevent the side walls of the formed concrete test block from having a large adhesion to the side walls of the test block mold 2 , which causes the side walls of the concrete test block to be damaged when the concrete test block is subjected to the upward thrust of the mold bottom plate 75 .

[0046] like Figures 1 to 11 As shown, the smearing assembly 9 includes a smearing roller 91 arranged on one side of the grouting head 4, support blocks 92 are arranged on both sides of the smearing roller 91, and the smearing roller 91 is rotatably arranged between the support blocks 92 through the rotating shafts at both ends, and a top frame 93 is arranged above the support block 92, and the top frame 93 is fixed on the side wall of the grouting head 4, and a connecting column 94 is longitudinally penetrated inside the top frame 93, and the bottom of the connecting column 94 is fixedly connected to the support block 92, and a spring 95 is wound around the outside of the connecting column 94, and the top of the spring 95 is fixedly connected to the top frame 93, and the bottom of the spring 95 is fixedly connected to the support block 92 The smear roller 91 is fixedly connected, a smearing wool sleeve 96 is fixed to the outer wall of the smearing roller 91, a storage chamber 97 is opened inside the smearing roller 91, a row hole 99 is opened at the top of the storage chamber 97, a sponge 98 is fixed to the top of the storage chamber 97, and the smearing component 9 also includes a liquid inlet pipe 910 arranged at the middle position of the rotating shaft at one end of the smearing roller 91, the liquid inlet pipe 910 is communicated with the storage chamber 97, and the liquid inlet pipe 910 is connected to one end of the injection pipe 63, a bearing 911 is fixed to the outside of the liquid inlet pipe 910, and the outer side of the bearing 911 is fixedly connected to the inner wall of the rotating shaft at one end of the smearing roller 91.

[0047] The bottom end of the coating roller 91 is lower than the highest point in the test block mold 2. The purpose is to ensure that when the top surface of the mold bottom plate 75 moves to a position on the same horizontal plane as the top of the test block mold 2, the bottom end of the coating roller 91 can contact the top surface of the mold bottom plate 75 to ensure coating, and when the mold bottom plate 75 starts to move downward from this position, the coating roller 91 and its external coating wool sleeve 96 can contact the top surface of the mold bottom plate 75 for a certain period of time to apply lubricating oil. When the tops are at the same horizontal plane, the top surface of the mold bottom plate 75 is in close contact with the smearing wool sleeve 96 and pushes up the smearing roller 91. The support blocks 92 on both sides of the smearing roller 91 drive the connecting column 94 to move up and squeeze the spring 95. When the spring 95 contracts, it exerts a reaction force on the support blocks 92, so that the smearing roller 91 located between the support blocks 92 is in close contact with the mold bottom plate 75. When the top surface of the mold bottom plate 75 is completely separated from the smearing roller 91 and the smearing wool sleeve 96, the smearing component 9 stops applying lubricating oil to the top surface of the mold bottom plate 75.

[0048] When the mold bottom plate 75 moves downward and drives the lubricating liquid storage component 6 to inject the lubricating oil, part of the lubricating oil is injected into the liquid inlet pipe 910 through the injection pipe 63 and the one-way valve 64, and the lubricating oil enters the storage cavity 97 through the liquid inlet pipe 910. When the reciprocating component 8 drives the grouting head 4 to move back and forth above the test block mold 2, it drives the smear roller 91 and its external smear wool sleeve 96 to move back and forth on the top surface of the mold bottom plate 75. The smear wool sleeve 96 and the smear roller 91 rotate under the action of friction, and the rotation of the smear roller 91 causes the storage cavity 97 to be filled with lubricating oil. The lubricating oil is discharged into the smearing sleeve 96 through the discharge hole 99 for adsorption. The smearing sleeve 96 smears the lubricating oil to the top surface of the mold bottom plate 75, so that the lubrication operation of the top surface of the mold bottom plate 75 can be completed. By lubricating the top surface of the mold bottom plate 75, the concrete test block formed in the test block mold 2 can be more easily removed from the mold bottom plate 75, and the bottom of the concrete test block will not be damaged when the concrete test block is removed from the mold bottom plate 75 due to excessive adhesion between the bottom of the concrete test block and the mold bottom plate 75;

[0049] A sponge 98 is provided in the storage chamber 97. The sponge 98 is located at the position of the discharge hole 99. The sponge 98 will preferentially absorb the lubricating oil. The sponge 98 can delay the discharge of the lubricating oil through the discharge hole 99 to prevent the lubricating oil from being discharged too much at one time, and the problem of too much lubricating oil being applied to a certain position of the mold bottom plate 75 and too little lubricating oil at another position will occur. In addition, to ensure the rotation of the smear roller 91, a motor can be installed at the end of the smear roller 91 where the liquid inlet pipe 910 is not provided to provide a driving force to rotate the smear roller 91. It should be noted that the liquid inlet pipe 910 is provided in the middle position of the rotating shaft on one side of the smear roller 91, and a bearing 911 is provided between the liquid inlet pipe 910 and the rotating shaft on one side of the smear roller 91. The bearing 911 can ensure that the rotation of the smear roller 91 will not affect the liquid inlet pipe 910, and the liquid inlet pipe 910, the bearing 911 and the storage chamber 97 must be sealed to prevent the lubricating oil in the storage chamber 97 from leaking through the gap between the liquid inlet pipe 910, the bearing 911 and the storage chamber 97.

[0050] like Figures 1 to 11 As shown, a slurry discharge groove 41 is provided inside the grouting head 4 , a bulk material plate 42 is fixed at the middle position inside the slurry discharge groove 41 , and a material distribution groove 43 is provided at the top of the slurry discharge groove 41 .

[0051] When the top surface of the mold base plate 75 is completely separated from the coating roller 91 and the coating sleeve 96, the coating component 9 stops applying lubricating oil to the top surface of the mold base plate 75, and then starts to inject concrete slurry into the test block mold 2, and uses the slurry guide pipe 5 to inject the slurry in the concrete slurry box 3 into the grouting head 4. The concrete slurry entering the grouting head 4 is first diverted through the dividing trough 43, and then flows into the bulk plate 42 in the slurry discharge trough 41. The bulk plate 42 can break up the concrete slurry before discharging it from the slurry discharge trough 41, which not only expands the discharge area of ​​the concrete slurry, but also slows down the outflow speed of the concrete slurry. The large area of ​​concrete slurry can better contact with the air and release the bubbles inside it into the air. The low flow rate of concrete slurry can reduce turbulence and prevent the excessive generation of new bubbles.

[0052] like Figures 1 to 11 As shown, the reciprocating assembly 8 includes a side frame 81 arranged at one end of the grouting head 4, a reciprocating screw 85 is rotatably arranged inside the side frame 81, a reciprocating screw sleeve 86 is threadedly connected to the outside of the reciprocating screw 85, and the reciprocating screw sleeve 86 is fixedly connected to one end of the grouting head 4, a motor 3 87 is installed on one side of the side frame 81, and the rotating shaft of the motor 3 87 extends into the side frame 81 and is connected to the reciprocating screw 85.

[0053] The motor 3 87 is started to drive the reciprocating screw 85 to rotate, and the reciprocating wire sleeve 86 is matched to reciprocate and translate outside the reciprocating screw 85. The grouting head 4 connected to the reciprocating wire sleeve 86 reciprocates and translates above the test block mold 2 under the action of the reciprocating wire sleeve 86. When the smearing roller 91 is used to smear the top surface of the mold bottom plate 75, the reciprocating grouting head 4 will drive the smearing roller 91 to reciprocate and translate on the top surface of the mold bottom plate 75, so as to expand the smearing area and make the lubricating oil more fully smeared on the top surface of the mold bottom plate 75.

[0054] When the top surface of the mold base plate 75 is completely separated from the coating roller 91 and the coating wool sleeve 96, the coating component 9 stops applying lubricating oil to the top surface of the mold base plate 75, and thereafter, starts to inject concrete slurry into the test block mold 2. The position of the mold base plate 75 when the slurry injection starts is called the initial grouting position. The grouting head 4 reciprocates above the mold base plate 75 and evenly spreads the slurry on the mold base plate 75. The slurry is continuously stacked together, and its height will increase. At the same time, as the mold base plate 75 moves downward, the increased top of the slurry is always maintained within the range of the initial grouting position with the grouting head 4, so that the injected slurry is always kept at a close distance from the grouting head 4. By reducing the distance between the grouting head 4 and the slurry, the problem of bubbles being generated due to the surrounding air being drawn in when the slurry is injected from a higher place is prevented.

[0055] like Figures 1 to 11 As shown, the reciprocating assembly 8 also includes a rotating block 83 fixed to the back of the side frame 81, a rotating bracket 82 is arranged outside the rotating block 83, the rotating bracket 82 is fixed to the side wall of the test block mold 2, the rotating block 83 is rotatably arranged in the rotating bracket 82, a motor 2 84 is installed at the bottom of the rotating block 83, and the rotating shaft at the top of the motor 2 84 is fixedly connected to the bottom of the rotating block 83.

[0056] After the concrete slurry is formed in the test block mold 2, in order to prevent the grouting head 4 and the smear component 9 from being located above the test block mold 2 and causing interference and affecting the demoulding of the concrete test block, the motor 2 84 can be started to drive the rotating block 83 to rotate, and the rotating block 83 drives the side frame 81, the reciprocating screw rod 85, the reciprocating wire sleeve 86 and the motor 3 87 to rotate, and the grouting head 4 and the smear component 9 fixed on the reciprocating wire sleeve 86 rotate accordingly, so as to move the grouting head 4 and the smear component 9 away from the top of the test block mold 2 to avoid affecting the demoulding of the test block mold 2. When the demoulding is completed, the motor 2 84 is used to drive the rotating block 83 to rotate so that the grouting head 4 and the smear component 9 can be reset. It should be noted here that since the smear roller 91 can retract upward through the support block 92, the connecting column 94 and the spring 95, when the smear roller 91 is removed from the test block mold 2, it will move up due to the resistance of the side wall of the test block mold 2, and will not interfere with the movement.
