Description

Technical Field

[0001] The invention relates to the technical field of pavement maintenance, and in particular to a convenient post-molding maintenance device for a concrete pavement. Background Art

[0002] After the concrete for the pavement is formed, in order to effectively reduce the evaporation rate of water on the surface of the concrete road and prevent the formation of early shrinkage cracks, it is necessary to regularly water and apply curing agent to the cover based on the ambient temperature and humidity on the basis of covering the concrete pavement with moisture.

[0003] At present, the traditional long-tube sprinkler system has exposed a significant drawback in the application of concrete pavement maintenance: its bulky tube body is not easy to quickly store and organize, resulting in a large amount of storage space being occupied during both working and non-working hours. This not only increases the level of disorder on the construction site, but also hides potential safety hazards such as tripping over workers and hindering the operation of other mechanical equipment.

[0004] Based on the above situation, the present invention proposes a convenient post-forming maintenance device for concrete pavement. Summary of the invention

[0009] Furthermore, it also includes a slide for lifting the card rack, the slide is slidably connected to the bracket, and the bracket is rotatably connected to a rotating frame for lifting the slide.

[0010] Furthermore, it also includes a detachable frame symmetrically distributed along the bracket, the detachable frame is fixedly connected to the bracket, and the detachable frame is pressed and matched with the adjacent clamping frame.

[0011] Furthermore, it also includes magnets symmetrically distributed along the first spring, and the symmetrically distributed magnets are respectively fixedly connected to the joint box and the retaining frame.

[0012] Furthermore, it also includes a blocking frame symmetrically distributed along the baffle frame, the blocking frame is fixedly connected to the baffle frame, and the side of the junction box close to the second hose is provided with drainage holes symmetrically distributed along the junction box, and the blocking frame is used to block the adjacent drainage holes.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The present invention uses hydraulic action to automatically extend the nozzles of the telescopic nozzle assembly outward in stages when spraying the curing solution, so that the curing solution is evenly sprinkled on the concrete pavement over a wide range. Moreover, through the elastic force of the first spring, when the spraying of the curing solution stops, the nozzles of the telescopic nozzle assembly automatically retract inward in stages, thereby avoiding the problem of occupying a large amount of storage space during operation and non-operation periods, and avoiding the problem of tripping over operators and obstructing the operation of other mechanical equipment.

[0018] The present invention prevents the nozzle of the telescopic nozzle assembly from sliding out quickly due to the high pressure of the hydraulic pressure by limiting the cooperation between the bracket and the bracket slot. Instead, the nozzle of the telescopic nozzle assembly is slowly adjusted to extend to a suitable length by controlling the rotating bracket to be stepped on multiple times. In this way, the length of the telescopic nozzle assembly can be adjusted and damage due to excessive impact can be avoided.

[0019] The present invention resists the hydraulic action through the magnetic attraction of the magnet, so that the retaining frame will not shake up and down due to the influence of small fluctuations in hydraulic pressure, thereby preventing the telescopic nozzle assembly from constantly swinging due to small fluctuations in hydraulic pressure, and improving the stability of the retaining frame and the telescopic nozzle assembly during operation.

[0020] The present invention quickly discharges the curing solution remaining in the telescopic nozzle assembly through the drainage hole, thereby preventing the curing solution from remaining inside the telescopic nozzle assembly due to slow discharge when the telescopic nozzle assembly contracts, thereby causing serious corrosion of the telescopic nozzle assembly.

[0021] The present invention can adjust the spray angle of the telescopic nozzle assembly by rotating the nut without affecting the swing and extension of the telescopic nozzle assembly, thereby enhancing practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: A convenient post-forming concrete pavement maintenance device, such as Figure 1-8 As shown, a trailer 1 is included, a handle 2 is fixedly connected to the left side of the top of the trailer 1, a high-pressure water tank 3 for storing a curing solution is fixedly connected to the side of the trailer 1 close to the handle 2, a first hose 4 is connected to the top of the high-pressure water tank 3, a bracket 5 is fixedly connected to the right side of the top of the trailer 1, a joint box 6 is fixedly connected to the middle of the bracket 5, the first hose 4 is connected to the joint box 6, the upper part of the bracket 5 is rotatably connected to a rotating frame 7 symmetrically distributed along the front and back of the bracket 5, the upper part of the joint box 6 is connected to a second hose 8 symmetrically distributed along the front and back of the joint box 6, and a telescopic nozzle assembly is rotatably connected to the rotating frame 7 Part 9, the telescopic nozzle assembly 9 is composed of three telescopic sliding nozzles, and one side of the nozzle is provided with spray holes distributed at equal intervals. When the telescopic nozzle assembly 9 is tilted toward the side close to the connector box 6, the telescopic nozzle assembly 9 is in a retracted state, and the telescopic nozzle assembly 9 is connected to the adjacent second hose 8. The upper part of the connector box 6 is slidably connected in the up and down directions with a retaining frame 10 for moving the telescopic nozzle assembly 9 back and forth. The retaining frame 10 is hydraulically driven to slide upward, thereby moving the telescopic nozzle assembly 9 to swing, and a first spring 11 is fixedly connected between the retaining frame 10 and the top of the inner side of the connector box 6.

[0033] First, a curing solution is formed by mixing a concrete pavement curing agent and water and poured into the high-pressure water tank 3. Then, the device is pushed onto the formed concrete pavement. Next, the high-pressure water tank 3 is opened, and the curing solution in the high-pressure water tank 3 enters the joint box 6 through the first hose 4. Under the action of hydraulic pressure, the retaining frame 10 slides upward, and the first spring 11 is compressed. When the retaining frame 10 slides upward, it pushes the side of the telescopic nozzle assembly 9 close to the second hose 8 to swing upward, thereby driving the rotating frame 7 to rotate, so that the telescopic nozzle assembly 9 swings to a horizontal state. At the same time, the curing solution entering the joint box 6 is sprayed into the telescopic nozzle assembly 9 through the second hose 8. Under the action of hydraulic pressure, each nozzle of the telescopic nozzle assembly 9 automatically extends outward step by step, and the curing solution is evenly sprayed on the concrete pavement through each nozzle. In this process, hold the handle 2 with both hands, or connect the device to the driving vehicle through the handle 2, so that the device moves straight to the left or right. In this way, the curing solution is evenly sprinkled on the concrete pavement over a large range.

[0034] When the curing solution in the high-pressure water tank 3 is used up halfway or the curing of the entire concrete pavement has been completed, the high-pressure water tank 3 needs to be closed. At this time, the retaining frame 10 that has lost its hydraulic action slides downward under the restoring action of the first spring 11, and the retaining frame 10 drives the telescopic nozzle assembly 9 to swing downward on the side close to the second hose 8, thereby driving the rotating frame 7 to rotate in the opposite direction, so that the telescopic nozzle assembly 9 swings to a state inclined toward the side of the joint box 6. At this time, each nozzle of the telescopic nozzle assembly 9 automatically contracts inward step by step.

[0035] In summary, the present invention uses hydraulic action to automatically extend the nozzles of the telescopic nozzle assembly 9 outward step by step when spraying the curing solution, so that the curing solution is evenly sprinkled on the concrete pavement over a large area, and through the elastic force of the first spring 11, when the spraying of the curing solution stops, the nozzles of the telescopic nozzle assembly 9 automatically retract inward step by step, thereby avoiding occupying a large amount of storage space during operation and non-operation periods, and avoiding the problem of tripping operators and hindering the operation of other mechanical equipment.

[0036] The support frame 12 is also provided with a slide 12, which is slidably connected to the support frame 5. The lower left side of the support frame 5 is rotatably connected to a rotating frame 13 for lifting the slide 12. The rotating frame 13 is arranged in a π shape. A fixing rod 14 is fixedly connected to the outer wall of the telescopic nozzle assembly 9. The fixing rod 14 is slidably connected to a clamping frame 15 along the up and down directions. The slide 12 moves upward and contacts with the clamping frame 15 for lifting the clamping frame 15. The telescopic portion of the telescopic nozzle assembly 9 is provided with clamping grooves 151 distributed at equal intervals. The clamping frame 15 is limitedly matched with the clamping grooves 151. A second spring 16 is fixedly connected between the fixing rod 14 and the adjacent clamping frame 15. A detaching frame 17 symmetrically distributed along the front and back of the support frame 5 is fixedly connected to the upper part of the support frame 5. The detaching frame 17 is squeezed and matched with the adjacent clamping frame 15 for releasing the clamping frame 15 from limiting the clamping groove 151.

[0037] If the nozzle of the telescopic nozzle assembly 9 slides out quickly due to the high pressure of the hydraulic pressure, it is easy to be damaged due to excessive impact force. Therefore, it is necessary to slow down the extension of the telescopic nozzle assembly 9. The specific operation is as follows:

[0038] When the telescopic nozzle assembly 9 is in a tilted state, the bracket 15 is squeezed by the detachment bracket 17, and the second spring 16 is in a compressed state. During the process of the telescopic nozzle assembly 9 swinging to a horizontal state, the fixing rod 14, the bracket 15 and the second spring 16 swing synchronously, so that the bracket 15 is disengaged from the detachment bracket 17. At this time, the second spring 16 is reset to drive the bracket 15 to slide downward and snap into a corresponding section of the slot 151 below. Subsequently, according to the width of the concrete pavement to be maintained, the nozzle of the telescopic nozzle assembly 9 can be slowly adjusted to a suitable length by controlling the rotating frame 13 to be stepped on multiple times.

[0039] The specific control method is: step on the left side of the rotating frame 13 to make the right side of the rotating frame 13 swing upward, thereby lifting the slide 12 upward, so that the slide 12 moves upward to contact with the bracket 15, and pushes the bracket 15 to slide upward to disengage from the slot 151, and the second spring 16 is compressed. At this time, the nozzle in the telescopic nozzle assembly 9 is extended to an appropriate length by the hydraulic pressure, and the foot is immediately released. The right side of the rotating frame 13 swings downward under the action of gravity, and the slide 12 slides downward under the action of gravity. When the slide 12 is separated from the bracket 15, the second spring 16 is reset to drive the bracket 15 to slide downward until it is inserted into a corresponding section of the slot 151 below. This is repeated until the nozzle of the telescopic nozzle assembly 9 extends to an appropriate length.

[0040] When the telescopic nozzle assembly 9 swings to a tilted state, the fixing rod 14, the bracket 15 and the second spring 16 swing synchronously therewith. When the bracket 15 contacts the detaching bracket 17, the bracket 15 slides upwards to disengage from the clamping groove 151 under the squeezing effect of the detaching bracket 17, and the second spring 16 is compressed. In this way, the nozzle of the telescopic nozzle assembly 9 is automatically retracted inward step by step without being affected.

[0041] It also includes magnets 18 symmetrically distributed up and down along the first spring 11 , and the magnets 18 symmetrically distributed up and down are fixedly connected to the joint box 6 and the retaining frame 10 respectively.

[0042] The high-pressure water tank 3 may be unstable in operation, resulting in small fluctuations in the output pressure, which in turn leads to small fluctuations in the hydraulic pressure. In order to prevent the retaining frame 10 from shaking up and down due to the small fluctuations in the hydraulic pressure, when the retaining frame 10 slides upward under the action of the hydraulic pressure, the retaining frame 10 drives the magnet 18 thereon to be adsorbed upward on the magnet 18 of the junction box 6. In this way, the hydraulic pressure is resisted by the magnetic attraction force, so that the retaining frame 10 will not shake up and down due to the small fluctuations in the hydraulic pressure, thereby preventing the telescopic nozzle assembly 9 from swinging continuously due to the small fluctuations in the hydraulic pressure, thereby improving the stability of the retaining frame 10 and the telescopic nozzle assembly 9 during operation. When the retaining frame 10 is no longer affected by the hydraulic pressure, the first spring 11 resets and drives the retaining frame 10 to slide downward, thereby separating the two magnets 18 from each other.

[0043] It also includes a blocking frame 19 symmetrically distributed along the front and back of the blocking frame 10, the blocking frame 19 is fixedly connected to the blocking frame 10, and a side of the junction box 6 close to the second hose 8 is provided with drainage holes 191 symmetrically distributed along the front and back of the junction box 6, and the blocking frame 19 is used to block adjacent drainage holes 191.

[0044] When the telescopic nozzle assembly 9 swings to the inclined state for contraction, a small part of the curing solution remaining in the telescopic nozzle assembly 9 will flow back into the joint box 6 through the second hose 8. Since the joint box 6 has a small volume, most of the curing solution will be discharged through the spray hole of the telescopic nozzle assembly 9. The discharge speed is slow, which affects the contraction of the telescopic nozzle assembly 9. For this reason, when the telescopic nozzle assembly 9 swings to the horizontal state for expansion, the blocking frame 10 drives the blocking frame 19 to block the drainage hole 191 upward to prevent the curing solution from leaking through the drainage hole 191. When the telescopic nozzle assembly 9 swings to the inclined state for contraction, the blocking frame 10 drives the blocking frame 19 to separate from the drainage hole 191 downward. At this time, the curing solution remaining in the telescopic nozzle assembly 9 will flow back to the drainage hole 191 through the second hose 8 for rapid discharge, which prevents the curing solution from remaining inside the telescopic nozzle assembly 9 due to slow discharge when the telescopic nozzle assembly 9 contracts, causing serious rust on the telescopic nozzle assembly 9.

[0045] It also includes a torsion spring 20 corresponding to the telescopic nozzle assembly 9, and both ends of the torsion spring 20 are fixedly connected to the adjacent rotating frame 7 and the telescopic nozzle assembly 9 respectively. A push frame 21 is slidably connected to the side of the bracket 5 close to the telescopic nozzle assembly 9 along the up and down directions. A push block 211 is fixedly connected to the side of the outer wall of the telescopic nozzle assembly 9 close to the push frame 21. The push block 211 is in contact with the push frame 21. The end surface of the push frame 21 close to the push block 211 is set to an arc surface to avoid affecting the forward and backward swinging of the telescopic nozzle assembly 9. The left side of the joint box 6 is rotatably connected to a screw rod 22, and a nut 23 is threadedly connected to the screw rod 22. The nut 23 is rotatably connected to the push frame 21.

[0046] In order to adjust the spray angle of the telescopic nozzle assembly 9 without affecting the swing and extension of the telescopic nozzle assembly 9, the specific operation is as follows:

[0047] When it is necessary to lower the spray angle, the nut 23 is rotated forward to move the push frame 21 upward, thereby pushing the telescopic nozzle assembly 9 to rotate through the push block 211, and the torsion spring 20 is deformed, so that the nozzle of the telescopic nozzle assembly 9 is adjusted downward. When it is necessary to increase the spray angle, the nut 23 is rotated reversely to move the push frame 21 downward. The push frame 21 no longer squeezes the push block 211, and the torsion spring 20 is reset to drive the telescopic nozzle assembly 9 to rotate reversely, so that the nozzle of the telescopic nozzle assembly 9 is adjusted downward.

[0048] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
