Description

Technical Field

[0001] The invention relates to the technical field of pavement maintenance, and in particular to a concrete pavement forming and hardening auxiliary device. Background Art

[0002] When the concrete pavement is formed and hardened in a cold environment, the hardening speed of the concrete pavement will be significantly reduced. By spraying high-temperature steam, the temperature around the concrete can be increased, thereby providing it with a more stable temperature and humidity environment, thereby accelerating the hydration reaction of cement and promoting faster hardening of the concrete.

[0003] After the steam contacts the concrete surface, it will gradually cool down and condense into water droplets. Some of the water will be absorbed by the concrete, but most of the steam will evaporate or be lost into the air. The large amount of steam evaporation means the waste of water resources, the increase of energy consumption and cost. In this way, more steam is needed to maintain the required temperature and humidity conditions. In order to ensure that the concrete is fully cured, it may be necessary to continuously spray steam, which requires a continuous increase in the number of water replenishment. The large amount of steam evaporation also means that the surrounding working environment is shrouded in a large amount of diffuse fog, which affects the temperature, humidity and vision of the working environment, and ultimately affects the stability and controllability of the hardening environment.

DETAILED DESCRIPTION

[0041] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way. Figure 1 To Attachment Fig.18 Embodiments of the present invention will be described.

[0042] Embodiment 1: A concrete pavement forming and hardening auxiliary device, refer to the attached Figure 1 To Attachment Figure 7, including a mounting frame 1, four rollers 101 are installed at the bottom of the mounting frame 1, a liquid storage tank 11 is fixedly connected to the left side of the lower part of the mounting frame 1, and the liquid storage tank 11 is used to store clean water. A liquid pump 12 is fixedly connected to the middle of the lower part of the mounting frame 1 and is symmetrically distributed along the front and back of the mounting frame 1. The liquid inlet end of the liquid pump 12 is connected to the liquid storage tank 11. An evaporator 13 is fixedly connected to the right side of the lower part of the mounting frame 1. The evaporator 13 is used to evaporate clean water into high-temperature steam. The liquid outlet end of the liquid pump 12 is connected to the evaporator 13. A spray rack 14 is fixedly connected to the lower right side of the mounting frame 1. The spray rack 14 sprays high-temperature steam onto the concrete pavement. The spray rack 14 is connected to the evaporator 13 through a connecting pipe 15. The spray rack 14 is connected to the suction rack 16 through an adapter rack 1601. By rotating the adapter frame 1601, the angle of the suction frame 16 can be fine-tuned. The suction frame 16 is connected to a first guide pipe 17. An air pump 18 is fixedly connected to the side of the mounting frame 1 close to the liquid pump 12. The first guide pipe 17 is connected to the air inlet end of the air pump 18. A cooling cylinder 19 is fixedly connected to the left side of the upper part of the mounting frame 1 for condensing high-temperature steam into liquid clean water. The top of the cooling cylinder 19 is connected to a second guide pipe 110 symmetrically distributed along the front and back of the cooling cylinder 19. The second guide pipe 110 is connected to the air outlet end of the air pump 18. The bottom of the cooling cylinder 19 is connected to a connecting pipe 111 symmetrically distributed along the front and back of the cooling cylinder 19. The connecting pipe 111 is connected to the liquid storage tank 11 for returning the cooled clean water into the liquid storage tank 11.

[0043] First, pour clean water into the liquid storage tank 11, then push the device onto the concrete pavement to be treated, then turn on the liquid pump 12 and the evaporator 13, the liquid pump 12 draws clean water from the liquid storage tank 11 into the evaporator 13, so that the clean water evaporates into high-temperature steam, enters the spray rack 14 through the connecting pipe 15, and then is sprayed onto the concrete pavement through the spray rack 14, thus playing an auxiliary maintenance effect on the forming and hardening of the concrete pavement.

[0044] In the above process, the air pump 18 is started. Under the suction of the air pump 18, the high-temperature steam that has not penetrated into the concrete pavement floats upward to the suction frame 16, and enters the air pump 18 through the suction frame 16 and the first guide pipe 17 in turn, and then is discharged into the cooling cylinder 19 through the second guide pipe 110, so that the high-temperature steam is cooled into liquid, and then flows back into the liquid storage tank 11 through the connecting pipe 111. In this way, the scattered steam is recycled, a large amount of steam evaporation is avoided, and the waste of resources is reduced, thereby reducing the number of times the liquid storage tank 11 is replenished with water, and at the same time reducing the impact on the temperature, humidity and line of sight of the surrounding working environment, which helps to create a more stable and controllable hardening environment and improve the quality of concrete.

[0045] See attached Figure 8 To Attachment Fig.11, also includes a storage barrel 2, the storage barrel 2 is fixedly connected to the upper right side of the mounting frame 1, a third guide pipe 21 is connected between the storage barrel 2 and the connecting pipe 15, a first guide pipe 17 is rotatably connected to a connecting shaft 22 on one side close to the storage barrel 2, a rotating blade 23 is fixedly connected to the bottom end of the connecting shaft 22, the rotating blade 23 is located in the first guide pipe 17, a reciprocating screw rod 24 is rotatably connected to the lower part of the storage barrel 2, the reciprocating screw rod 24 is fixedly connected to the connecting shaft 22, a circular extrusion block 25 is threadedly connected to the reciprocating screw rod 24, and the storage barrel 2 is provided with two slide grooves 26 for limiting and guiding the extrusion block 25, the slide grooves 26 is composed of an inclined portion and a vertical portion. The storage barrel 2 is arranged as a hollow cylinder near the extrusion block 25. The reciprocating screw 24 and the extrusion block 25 are both located in the cylinder. A dividing line 201 is arranged on the inner wall of the cylinder. The inclined portion and the vertical portion of the slide groove 26 are bounded by the dividing line 201. The inner diameter value between the cylinder dividing line 201 and the limit ridge 202 is equal to the outer diameter value of the extrusion block 25. The inner diameter value above the cylinder dividing line 201 gradually decreases from top to bottom, so that when the extrusion block 25 slides up and down along the inclined portion of the slide groove 26, there is a gap between the inner wall of the storage barrel 2 and the extrusion block 25.

[0046] A sufficient amount of liquid hardener for concrete pavement is added into the storage barrel 2. Under the action of the air pressure of the first guide pipe 17, the rotating blade 23 drives the connecting shaft 22 to rotate, thereby driving the reciprocating screw rod 24 to rotate, and then driving the extrusion block 25 to reciprocate up and down.

[0047] In the above process, when the extrusion block 25 slides up and down along the inclined portion of the slide groove 26, there is a gap between the inner wall of the storage bucket 2 and the extrusion block 25, and the liquid concrete hardener in the upper part of the storage bucket 2 flows downward to the lower part of the storage bucket 2 through the gap.

[0048] When the extrusion block 25 slides downward along the slide groove 26 until it contacts the inner wall of the storage barrel 2, at this time, the extrusion block 25 moves to the intersection of the inclined part and the vertical part of the slide groove 26 (i.e., the dividing line 201), and the extrusion block 25 closes the upper part of the storage barrel 2, interrupting the flow of the liquid hardener of the concrete pavement from top to bottom, and then the extrusion block 25 continues to slide downward along the vertical part of the slide groove 26. At this time, the cooperation between the extrusion block 25 and the storage barrel 2 is similar to a cylinder piston structure, so that the liquid hardener of the concrete pavement in the lower part of the storage barrel 2 is intermittently squeezed to the connecting pipe 15 through the third guide pipe 21, and mixed into the high-temperature steam, so that the high-temperature steam carries the liquid hardener of the concrete pavement and sprays it onto the concrete pavement. On the basis of the high-temperature steam, the liquid hardener of the concrete pavement helps to further harden the concrete pavement. At the same time, the high-temperature steam helps the liquid hardener of the concrete to penetrate and function better, that is, the high-temperature steam and the liquid hardener of the concrete play a good synergistic role.

[0049] See attached Figure 6 , Attachment Figure 7 , Attachment Fig.12 and attached Fig.13 , and also includes a pressing frame 3 symmetrically distributed along the front and back of the mounting frame 1, the pressing frame 3 is rotatably connected to the mounting frame 1, and a plurality of splicing frames 31 are stacked and placed on one side of the mounting frame 1 close to the pressing frame 3, and the structure of each splicing frame 31 is the same as the composite structure of the spray frame 14, the suction frame 16, and the adapter frame 1601, and the splicing frame 31 and the suction frame 16 are fixedly connected to two connectors 1602 for splicing, and the mounting frame 1 is fixedly connected to one side of the pressing frame 3 with limiting frames symmetrically distributed along the front and back of the mounting frame 1 The limiting plate 32 is used to limit the front and rear ends of the splicing frame 31. The mounting frame 1 is fixedly connected to the right side of the pressing frame 3 with a support frame 34 symmetrically distributed along the front and rear of the mounting frame 1. The support frame 34 is in contact with the adjacent pressing frame 3. The support frame 34 is slidably connected to the limiting block 35 symmetrically distributed along the front and rear of the support frame 34 along the front and rear directions. The limiting block 35 is used to press the pressing frame 3 to the left on the adjacent supporting frame 34, and a spring piece 33 is fixedly connected between adjacent limiting blocks 35.

[0050] The cam 33 is pressed against the support frame 34 and the two adjacent limit blocks 35 are pressed against the support frame 34.

[0051] See attached Fig. 9 , Attachment Fig.14 and attached Fig.15 , and also includes a radiator 41 symmetrically distributed along the front and back of the cooling cylinder 19. The radiator 41 is fixedly connected to the cooling cylinder 19. A fan 42 is fixedly connected to the radiator 41. Three cylindrical through grooves are opened on the inner wall of the cooling cylinder 19. The fan 42 guides cold air into the cylindrical through grooves to cool the cooling cylinder 19. A protective plate 4 symmetrically distributed along the front and back of the mounting frame 1 is fixedly connected to the upper left side of the mounting frame 1. The protective plate 4 is used to protect the adjacent fan 42.

[0052] When high-temperature steam encounters the cooling cylinder 19, heat will be transferred to the cooling cylinder 19, causing the cooling capacity of the cooling cylinder 19 to be weakened. In order to maintain the cooling capacity of the cooling cylinder 19, the radiator 41 and the fan 42 are needed to assist the cooling cylinder 19 in timely heat dissipation, and the protective plate 4 prevents the staff from getting close to the fan 42 and being scratched by the fan blades.

[0053] See attached Figure 1 , Attachment Fig.16 , Attachment Fig.17 and attached Fig.18 , and also includes a hopper 5 for containing plastic film debris. The hopper 5 is fixed to the lower left part of the mounting frame 1. The lower part of the hopper 5 is rotatably connected to a roller shaft 51, and a groove is opened on the roller shaft 51. A pulley assembly 52 is connected between the roller 101 and the adjacent roller shaft 51.

[0054] In order to ensure the effective effect of steam, prevent the rapid loss of heat and humidity, achieve the effect of heat preservation and moisture retention, so that the concrete surface is evenly heated, accelerate the process of concrete hydration, and improve the strength and durability of the concrete pavement, before spraying steam, it is necessary to cover the concrete pavement with a layer of covering material. The specific operation is as follows: plastic film fragments are placed in the hopper 5 as a covering material for the concrete pavement. When the roller 101 moves to the left, the roller 101 drives the roller 51 to rotate through the pulley assembly 52. ​​When the groove of the roller 51 rotates toward the side close to the hopper 5, the plastic film fragments in the hopper 5 gradually fall into the groove of the roller 51. When the groove of the roller 51 rotates toward the side close to the concrete pavement, the plastic film fragments in the groove are spread on the concrete pavement. In this way, before the concrete pavement is subjected to high-temperature steam curing, a layer of covering material is automatically spread first. In this way, a relatively closed environment is maintained to maintain the heat and humidity of the steam.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
