Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and specifically to a concrete heating curing device. Background Art

[0002] After the concrete precast is poured, it is necessary to avoid the rapid decrease in temperature. Therefore, it is necessary to heat and cure the concrete precast. The existing curing method is the steam curing method. The existing steam use cost is relatively high, the flexibility is poor, and the steam heat waste is relatively large.

[0003] Chinese Patent Publication No. CN211250638U discloses a heating and curing device for precast concrete components, including a curing box. The curing box is a rectangular box body, with a box door installed on one side. The upper part of the inner cavity of the curing box is fixed with an arc-shaped top plate. The lower part of the arc-shaped top plate is fixed with a heating pipe fixing cover through a pull rod. Heating pipes are evenly installed in the heating pipe fixing cover. An electric heating intelligent control box is fixed on the top of the curing box. The electric heating intelligent control box is connected to the heating pipes through line control. The electric heating intelligent control box is provided with a voltmeter, a main switch, more than one temperature increase switch, a switch indicator light, and a temperature setting device.

[0004] The above solution provides a concrete steam curing device. The above solution uses an electric heating method to heat the concrete precast. However, during the heating process, it is necessary to timely replenish water to the concrete precast. Otherwise, the concrete precast is prone to cracking during the heating process. Although the traditional steam curing method has a large steam consumption, it can avoid the cracking of the concrete precast during the curing process. Therefore, the steam curing method can better ensure the quality of the concrete precast compared with the above solution. However, when curing the concrete precast by the steam curing method, there is a situation where part of the steam accumulates on the upper surface of the concrete precast, resulting in uneven heating of the concrete precast during the heating process, and thus reducing the strength of the concrete. Summary of the Invention

[0005] In view of the above problems, a concrete heating curing device is provided. By horizontally and fixedly arranging a support shaft in a curing shed, hinging a bracket on the support shaft, and fixedly arranging a counterweight block on the lower side of the bracket. After the concrete precast is completely received by the receiving end face, a push rod arranged on one side of the bracket pushes the bracket, causing the bracket to tilt. Subsequently, the push rod quickly withdraws, and the bracket swings reciprocally under the action of the counterweight block. The concrete precast arranged on the receiving end face swings synchronously with the bracket, and the accumulated water on the concrete precast is smoothly discharged when the concrete precast tilts.

[0006] To solve the problems of the prior art, the present invention provides a concrete heating and curing device, including a curing shed; a support shaft is fixedly arranged along the length direction of the curing shed in the curing shed, a bracket is hinged on the support shaft, the upper part of the bracket is provided with a receiving end face for receiving concrete precast members, and the receiving end face is located above the support shaft. A counterweight is fixedly arranged on the bracket below the support shaft, and a push rod capable of pushing the bracket to swing is movably arranged along the width direction of the curing shed on one side of the bracket.

[0007] Preferably, a roller is rotatably arranged at the lower end of the bracket, and an arc-shaped guide rail fixedly connected with the curing shed is arranged on one side of the roller. The arc-shaped guide rail is in rolling cooperation with the roller.

[0008] Preferably, a sliding sleeve is fixedly arranged along the width direction of the curing shed on the inner wall of the curing shed. The push rod extends into the sliding sleeve and is in sliding cooperation with the sliding sleeve. An air pump and a first on-off valve are arranged at the end of the sliding sleeve far away from the push rod.

[0009] Preferably, a hinge seat is fixedly arranged at the end of the push rod, and a push wheel in rolling cooperation with the side wall of the bracket is rotatably arranged on the hinge seat.

[0010] Preferably, a rubber ring is fixedly arranged at one end of the sliding sleeve where the push rod is arranged.

[0011] Preferably, an electric push rod is horizontally arranged in the curing shed. The electric push rod and the push rod are respectively located on both sides of the bracket. When the bracket is in a vertical state, the driving end of the electric push rod and the end of the push rod are respectively in contact with both sides of the bracket.

[0012] Preferably, a nozzle for spraying steam is arranged at the upper part of the curing shed, a water suction pipeline for supplying the accumulated water at the bottom of the curing shed to the nozzle is arranged on one side of the nozzle, and a steam generator is arranged on the water suction pipeline.

[0013] Preferably, a partition board is vertically and fixedly arranged at the bottom of the curing shed. The partition board divides the bottom of the curing shed into a settlement area and a clear water area, and the water pumping unit is communicated with the clear water area.

[0014] Preferably, a guide plate fixedly connected with the inner wall of the curing shed is obliquely arranged at the upper part of the partition board.

[0015] Preferably, a plurality of driving wheels for driving the concrete precast members to move into or out of the receiving end face are evenly and rotatably arranged along the length direction of the curing shed on the receiving end face. An electric motor is arranged at the end of the driving wheel.

[0016] The beneficial effects of the present invention compared with the prior art are:

[0017] 1. In the present invention, a support shaft is horizontally and fixedly arranged in a curing shed, and a bracket is hinged on the support shaft. Meanwhile, a counterweight is fixedly arranged on the lower side of the bracket. After the concrete precast member is completely received by the receiving end face, a push rod arranged on one side of the bracket pushes the bracket, causing the bracket to tilt. Subsequently, the push rod quickly withdraws, and the bracket swings reciprocally under the action of the counterweight. The concrete precast member arranged on the receiving end face swings synchronously with the bracket, and the accumulated water on the concrete precast member is smoothly discharged when the concrete precast member tilts. In summary, the present invention not only avoids the accumulation of water on the upper end face of the concrete precast member during the steam curing process, ensuring the strength of the concrete precast member after curing, but also does not require the push rod to always push the bracket, reducing energy consumption.

[0018] 2. By providing a sliding sleeve, an air pump, and a first switching valve, when it is necessary to push and swing the bracket, the first switching valve is in a closed state. Subsequently, the air pump discharges gas into the sliding sleeve. As the gas enters the sliding sleeve, the push rod slidably arranged in the sliding sleeve gradually extends and pushes the bracket to tilt. When the push rod pushes the bracket to the rated tilt angle, the air pump stops operating, and the first switching valve opens. The bracket pushes the push rod back into the sliding sleeve, realizing that after the bracket tilts to the rated angle, by opening the first switching valve, the push rod can quickly disengage from the support of the bracket, enabling the bracket to swing automatically under the action of the counterweight. When the swing of the bracket stops, the first switching valve closes, and the air pump is turned on again, repeating the cycle. This not only ensures that the bracket can be in a continuous swinging state but also avoids the high energy consumption problem when the push rod continuously drives the bracket to swing.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1-3 and Figures 5-7 : A concrete heating and curing device comprises a curing shed 1; a support shaft 11 is fixedly arranged in the curing shed 1 along the length direction of the curing shed 1, a bracket 2 is hinged on the support shaft 11, a receiving end surface 21 for receiving a concrete prefabricated part 3 is provided on the upper part of the bracket 2, and the receiving end surface 21 is located above the support shaft 11, a counterweight block 22 is fixedly arranged on the bracket 2 below the support shaft 11, and a push rod 12 that can push the bracket 2 to swing is movably arranged on one side of the bracket 2 along the width direction of the curing shed 1.

[0034] After the concrete precast member 3 is formed, it needs to be placed in a steam curing shed for curing, which avoids the cracking phenomenon of the concrete precast member 3 caused by low temperature. When the existing steam curing shed 1 cures the concrete precast member 3, although the high-temperature steam can surround the concrete precast member 3, the spatial state of the concrete precast member 3 located in the curing shed 1 will not change, which easily leads to water accumulation residues on the upper surface of the concrete precast member 3, resulting in a lower temperature at the water accumulation area compared to other positions, and then causing uneven heating of the concrete precast member 3 during steam curing, and further reducing the strength of the concrete precast member 3.

[0035] In order to avoid the above situation, the existing concrete heating and curing device is redesigned so that there is no water accumulation when the concrete heating and curing device cures the concrete precast member 3, avoiding the uneven heating of the concrete precast member 3 due to water accumulation during steam curing, and ensuring the strength of the concrete precast member 3. The specific structure and working process of the concrete heating and curing device in the present invention are as follows:

[0036] When curing the precast concrete member 3, the precast concrete member 3 is first fed into the curing shed 1 horizontally from one end of the curing shed 1. The top of the curing shed 1 is provided with nozzles 14 capable of spraying steam, and the nozzles 14 start spraying steam during the process of placing the precast concrete member 3. The precast concrete member 3 entering the curing shed 1 is received by the receiving end face 21 of the support 2. The receiving end face 21 is located above the support shaft 11. When the precast concrete member 3 is pushed into the curing shed 1, the receiving end face 21 is parallel to the horizontal plane, and at this time the support 2 is in a static state. After the precast concrete member 3 is completely pushed into the curing shed 1, the push rod 12 arranged on one side of the support 2 starts to move. The push rod 12 pushes the support 2 located below the support shaft 11, and the support 2 tilts around the support shaft 11 under the action of the push rod 12. When the push rod 12 pushes the support 2 to tilt to the rated angle, the push rod 12 quickly retracts. Since the support 2 is hinged to the support shaft 11, when the push rod 12 retracts, the support 2 drives the precast concrete member 3 arranged on the receiving end face 21 to swing synchronously. And in order to ensure the swingability of the support 2, a counterweight 22 is also arranged on the support 2. The counterweight 22 is located below the support shaft 11, so that the overall center of gravity of the support 2 is located below the support shaft 11, avoiding the situation that the support 2 cannot swing after tilting. Due to the action of the counterweight 22, the support 2 drives the precast concrete block to swing reciprocally after the push rod 12 withdraws. At this time, the accumulated water on the upper end face of the precast concrete block will spill due to the swing of the precast concrete member 3, avoiding the situation of water accumulation on the upper part of the precast concrete block during the steam curing process. At the same time, the push rod 12 quickly retracts after pushing the support 2 to tilt, avoiding the need for the push rod 12 to continuously push the support 2 to swing reciprocally, reducing the energy consumption. The push rod 12 only needs to be started intermittently and push the support 2 that has been restored from the tilted state to the vertical state again.

[0037] By horizontally and fixedly arranging the support shaft 11 in the curing shed 1, hinging the support 2 on the support shaft 11, and fixedly arranging a counterweight 22 on the lower side of the support 2, after the precast concrete member 3 is completely received by the receiving end face 21, the push rod 12 arranged on one side of the support 2 pushes the support 2 to make the support 2 tilt, and then the push rod 12 quickly withdraws. The support 2 swings reciprocally under the action of the counterweight 22, and the precast concrete member 3 arranged on the receiving end face 21 swings synchronously with the support 2, and the accumulated water on the precast concrete member 3 is smoothly discharged when the precast concrete member 3 tilts. In summary, the present invention not only avoids the situation of water accumulation on the upper end face of the precast concrete member 3 during the steam curing process, ensures the strength of the precast concrete member 3 after curing, but also does not need to continuously push the support 2 by the push rod 12, reducing the energy consumption.

[0038] Refer to Figure 4:A roller 23 is rotatably arranged at the lower end of the support 2, and an arc-shaped guide rail 24 fixedly connected to the curing shed 1 is arranged on one side of the roller 23. The arc-shaped guide rail 24 is in rolling cooperation with the roller 23.

[0039] When the support 2 swings, the roller 23 rolls back and forth on the arc-shaped guide rail 24. By arranging the roller 23 and the arc-shaped guide rail 24, the support shaft 11 no longer supports the support 2 alone. When a concrete precast member 3 is received on the receiving end face 21 of the support 2, the weight borne by the support shaft 11 is relatively large. After the roller 23 and the arc-shaped guide rail 24 are arranged, they can jointly provide support for the support 2 with the support shaft 11, avoiding the situation that the support shaft 11 is bent and deformed after bearing a large weight for a long time.

[0040] Refer to Figure 10 :A sliding sleeve 121 is fixedly arranged on the inner wall of the curing shed 1 along the width direction of the curing shed 1. The push rod 12 extends into the sliding sleeve 121 and is in sliding cooperation with the sliding sleeve 121. An air pump 122 and a first switch valve 123 are arranged at the end of the sliding sleeve 121 away from the push rod 12.

[0041] When it is necessary to push and swing the support 2, the first switch valve 123 is in the closed state. Subsequently, the air pump 122 discharges gas into the sliding sleeve 121. As the gas enters the sliding sleeve 121, the push rod 12 slidably arranged in the sliding sleeve 121 gradually extends and pushes the support 2 to tilt. When the push rod 12 pushes the support 2 to the rated tilt angle, the air pump 122 stops operating, and the first switch valve 123 is opened. The support 2 pushes the push rod 12 back into the sliding sleeve 121, realizing that after the support 2 is tilted to the rated angle, by opening the first switch valve 123, the push rod 12 can quickly disengage from the support of the support 2, enabling the support 2 to swing automatically under the action of the counterweight 22. When the swing of the support 2 stops, the first switch valve 123 is closed, and the air pump 122 is opened again, repeating the cycle, which not only ensures that the support 2 can be in a continuous swinging state but also avoids the high energy consumption problem when the push rod 12 continuously drives the support 2 to swing.

[0042] Refer to Figure 8 :A hinge seat 124 is fixedly arranged at the end of the push rod 12, and a push wheel 125 in rolling cooperation with the side wall of the support 2 is rotatably arranged on the hinge seat 124.

[0043] If the support 2 is directly pushed and swung by the end of the push rod 12, the wear between the push rod 12 and the support 2 is relatively large. After long-term use, it is easy to cause the strength of the support 2 to decline.

[0044] Refer to Figure 9 :A rubber ring 1211 is fixedly arranged at one end of the sliding sleeve 121 where the push rod 12 is arranged.

[0045] After the first switching valve 123 is opened, the support 2 drives the push rod 12 to retract into the sliding sleeve 121. To prevent the hinge seat 124 provided at the end of the push rod 12 from hitting the end of the sliding sleeve 121, a rubber ring 1211 is provided at the end of the sliding sleeve 121.

[0046] Refer to Figure 7 : A power push rod 13 is horizontally arranged in the curing shed 1. The power push rod 13 and the push rod 12 are respectively located on both sides of the support 2. When the support 2 is in a vertical state, the driving end of the power push rod 13 and the end of the push rod 12 are respectively in contact with both sides of the support 2.

[0047] When the concrete precast member 3 is fed, only contacting one side of the support 2 through the push rod 12 cannot ensure the stability of the support 2. When the support 2 is in a vertical state, both sides of the support 2 are clamped by the power push rod 13 and the push rod 12 at the same time, so that the support 2 will not rotate around the support shaft 11, ensuring the stability of the support 2 when receiving the concrete precast member 3 through the receiving end face 21.

[0048] Refer to Figure 3 : A spray head 14 for spraying steam is arranged at the upper part of the curing shed 1. A water extraction pipeline 15 for supplying the accumulated water at the bottom of the curing shed 1 to the spray head 14 is arranged on one side of the spray head 14, and a steam generator 151 is arranged on the water extraction pipeline 15.

[0049] Refer to Figure 6 : A partition plate 16 is vertically and fixedly arranged at the bottom of the curing shed 1. The partition plate 16 divides the bottom of the curing shed 1 into a sedimentation area 161 and a clear water area 162, and the water extraction unit is communicated with the clear water area 162.

[0050] Refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 7 : A guide plate 17 fixedly connected to the inner wall of the curing shed 1 is obliquely arranged at the upper part of the partition plate 16.

[0051] When the support 2 drives the concrete precast member 3 to tilt and swing, the accumulated water on the concrete precast member 3 drives some sediment to fall to the bottom of the curing shed 1. The partition plate 16 divides the bottom of the curing shed 1 into a sedimentation area 161 for sedimentation of sediment and a clear water area 162. The water flow containing sediment first falls into the sedimentation area 161, the sediment in the water settles in the sedimentation area 161, and the upper water flow crosses the partition plate 16 and enters the clear water area 162. A filter screen is also arranged at the connection port of the water extraction pipeline 15 and the clear water area 162, ensuring that the water extraction pipeline 15 will not pump the water containing sediment into the steam generator 151.

[0052] Refer to Figure 11: A plurality of drive wheels 211 for driving the concrete precast member 3 to move into or out of the receiving end face 21 are evenly and rotatably arranged on the receiving end face 21 along the length direction of the curing shed 1, and a motor is arranged at the end of the drive wheel 211.

[0053] The motor is used to drive the drive wheel 211 to rotate. A second switching valve 18 communicating with the clear water area 162 is fixedly arranged on the side wall of the curing shed 1. When the water level in the clear water area 162 is relatively low, the second switching valve 18 is opened to replenish water to the clear water area 162. A water level sensor for detecting the water level is arranged in the clear water area 162. When the water level in the clear water area 162 is lower than the water level sensor, the second switching valve 18 is opened, and water flows into the clear water area 162 through the second switching valve 18.

[0054] Working principle: When curing the concrete precast member 3, first send the concrete precast member 3 into the curing shed 1 horizontally from one end of the curing shed 1. A nozzle 14 capable of spraying steam is arranged at the top of the curing shed 1, and the nozzle 14 starts to spray steam during the process of placing the concrete precast member 3. The concrete precast member 3 entering the curing shed 1 is received by the receiving end face 21 of the support 2. The receiving end face 21 is located above the support shaft 11. When pushing the concrete precast member 3 into the curing shed 1, the receiving end face 21 is parallel to the horizontal plane, and at this time the support 2 is in a static state. After the concrete precast member 3 is completely pushed into the curing shed 1, the push rod 12 arranged on one side of the support 2 starts to move. The push rod 12 pushes the support 2 located below the support shaft 11. The support 2 tilts around the support shaft 11 under the action of the push rod 12. When the push rod 12 pushes the support 2 to tilt to the rated angle, the push rod 12 quickly retracts. Since the support 2 is hinged to the support shaft 11, when the push rod 12 retracts, the support 2 drives the concrete precast member 3 arranged on the receiving end face 21 to swing synchronously. And in order to ensure the swingability of the support 2, a counterweight 22 is also arranged on the support 2. The counterweight 22 is located below the support shaft 11, so that the overall center of gravity of the support 2 is located below the support shaft 11, avoiding the situation that the support 2 cannot swing after tilting. Through the action of the counterweight 22, the support 2 drives the concrete precast block to swing reciprocally after the push rod 12 withdraws. At this time, the accumulated water gathered on the upper end face of the concrete precast block will fall due to the swing of the concrete precast member 3, avoiding the situation of water accumulation on the upper part of the concrete precast block during the steam curing process. At the same time, the push rod 12 quickly retracts after pushing the support 2 to tilt, avoiding the need for the push rod 12 to continuously push the support 2 to swing reciprocally, reducing the energy consumption. The push rod 12 only needs to be started intermittently and push the support 2 that has been restored from the tilted state to the vertical state again.

[0055] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations and improvements can still be made, and these all fall within the protection scope of the present invention.
