[0003] Therefore, the present application is proposed. SUMMARY

[0004] To solve the above technical problems, the basic idea of the technical scheme adopted by the present application is:

[0005] A kind of concrete curing device of cast-in-situ beam slab of pivot intercommunication super major bridge, including the mobile car body of being arranged at one side of the body of cast-in-situ beam slab of super major bridge, still including the mounting bracket of being fixed on the upper end of mobile car body, the upper end of mounting bracket is connected with U type frame through steering assembly, U type frame is provided with wetting curing assembly for wetting and curing the surface of the body of cast-in-situ beam slab of super major bridge;

[0006] The wetting curing assembly includes a mounting seat, the mounting seat is connected with a mounting plate on one side through a connecting assembly, the mounting plate is fixed with a sponge plate on one side, the mounting plate is provided with a water injection assembly for injecting water into the sponge plate, and the mounting seat is provided with an extrusion assembly for extruding the mounting plate.

[0007] The water injection assembly includes a plurality of water injection pipes mounted on the mounting plate, one end of each water injection pipe is arranged towards the upper end of the sponge plate, the upper end of the mounting plate is provided with a connecting pipe, one end of each water injection pipe is fixed in communication with the inside of the connecting pipe, and the connecting pipe is connected with the water outlet end of an external water pump through a hose.

[0008] The connecting assembly includes a plurality of sleeves fixed on the mounting plate, each sleeve is slidably connected with a slide rod, one end of the slide rod is fixed with the mounting seat, and a spring is arranged outside each sleeve.

[0009] The extrusion assembly includes a mounting slot formed in the mounting seat, the mounting slot is provided with a cam for extruding and pushing the mounting plate, and the mounting seat is provided with a driving assembly for driving the cam.

[0010] The driving assembly includes a support frame fixed on a mounting seat, a driving shaft is rotatably connected to the support frame, the cam is fixed on the driving shaft, and a first motor for driving the driving shaft is installed on the support frame.

[0011] The steering assembly includes a fixed plate fixed to the upper end of the mounting frame, a connecting shaft is rotatably connected to the fixed plate, a connecting plate is fixed on the connecting shaft, the connecting plate is fixed to one side of the U-shaped frame, a second motor for driving the connecting shaft is installed on the fixed plate, and the output end of the third motor is connected to a slider via a lead screw.

[0012] The inventors have found that, because the sponge board releases water when squeezed, a negative pressure is generated when it is reset, causing the surface concrete of the cast-in-place beam and slab of the super-large bridge to reversely extract water after being moistened, resulting in sanding of the surface concrete. Therefore, based on the above embodiment, the following improvements are made:

[0013] The moisturizing and health care component also includes side plates installed on the mounting plate and a feed plate installed on the outside of the sponge plate. The feed plate and the side plates are each provided with two groups. The two groups of side plates are arranged front and back along the movement direction of the moving body. The side plate is arranged on the side of the feed plate facing away from the sponge plate. A ratchet structure is provided between the feed plate and the side plates. A T-shaped slide groove is provided on the mounting plate. The interior of the T-shaped slide groove is connected to a T-shaped slider through a spring. The T-shaped slider is fixedly installed on the side plate. An electromagnet is installed in the T-shaped slide groove. An iron block corresponding to the position of the electromagnet is provided on the T-shaped slider.

[0014] After the sponge plate contacts the surface of the cast-in-place beam and slab of the super-large bridge, as the sponge plate is continuously squeezed out of water, the ratchet structure will limit the reverse reset of the sponge plate, and thus there will be no negative pressure to reversely extract water from the surface of the cast-in-place beam and slab of the super-large bridge. When the sponge plate is separated from the surface of the cast-in-place beam and slab of the super-large bridge and does not contact the surface of the cast-in-place beam and slab of the super-large bridge after reset, the electromagnet turns on (power is turned on to generate a magnetic field) to attract the iron block until the sponge plate drives the feed plate to reset to its initial state.

[0015] A method for curing cast-in-place beam and slab concrete of a hub interchange super-large bridge, the curing steps are as follows:

[0016] Step 1: Angle alignment

[0017] The second motor is started to drive the connecting shaft to rotate. During the rotation of the connecting shaft, the U-shaped frame is driven to rotate and adjust through the connection of the connecting plate. The rotation of the U-shaped frame drives the mounting seat, the mounting plate and the sponge plate to rotate synchronously. The rotation of the sponge plate makes the sponge plate flush with the outer surface of the cast-in-place beam and slab of the super-large bridge.

[0018] Step 2: Align the starting end

[0019] The moving vehicle body is arranged at one end of the side of the cast-in-place beam slab body of the super-large bridge, so that one end of the sponge plate is flush with the starting end of the cast-in-place beam slab body of the super-large bridge in the moving direction, and the sponge plate moves along the length direction of the cast-in-place beam slab body of the super-large bridge;

[0020] Step three, water injection

[0021] Through the pumping effect of the water pump and the connecting effect of the hose, the external water is transported towards the connecting pipe and flows out of the sponge plate through each water injection pipe, and the water injection of the sponge plate is completed.

[0022] Step four, wet maintenance

[0023] The first motor is started to drive the cam on the drive shaft to rotate. During the rotation of the cam, the cam first abuts against the mounting plate, then pushes the mounting plate to move towards the side of the cast-in-place beam slab body of the super-large bridge, so that the sponge plate abuts against the side of the cast-in-place beam slab body of the super-large bridge, and then the sponge plate is squeezed. During the squeezing process, because the sponge plate abuts against the side surface of the cast-in-place beam slab body of the super-large bridge, the water adsorbed on the sponge plate flows to the side surface of the cast-in-place beam slab body of the super-large bridge, and the cast-in-place beam slab body of the super-large bridge is wet maintained.

[0024] The third motor is started when the sponge plate contacts the surface of the cast-in-place beam slab body of the super-large bridge, drives the sliding block to move against the moving direction of the moving vehicle body, and the speed is equal to the speed of the moving vehicle body. When the sponge plate is separated from the surface of the cast-in-place beam slab body of the super-large bridge, the third motor is reversely rotated, moves along the moving direction of the moving vehicle body to the initial position, and needs to be reset before the next sponge plate contacts the surface of the cast-in-place beam slab body of the super-large bridge.

[0025] When the sponge plate contacts the surface of the cast-in-place beam slab body of the super-large bridge, the sponge plate is compressed in one direction through the ratchet structure between the feeding plate and the side plate as the mounting plate is continuously squeezed by the cam. When the sponge plate is separated from the surface of the cast-in-place beam slab body of the super-large bridge and is reset without contacting the surface of the cast-in-place beam slab body of the super-large bridge, the electromagnet is opened to adsorb the iron block until the sponge plate drives the feeding plate to reset to the initial state.

[0026] Compared with the prior art, the present application has the following advantages:

[0027] The hinge interworking super-large bridge cast-in-place beam slab concrete curing device of the present application can wet and maintain the hinge interworking super-large bridge cast-in-place beam slab body through the cooperation of the wet maintenance assembly, the water injection assembly and the squeezing assembly. During the maintenance process, the water sprayed by the sponge plate is first buffered and adsorbed, and then slowly flows out through the squeezing effect, which avoids the phenomenon of direct spraying of water causing cracks and sanding on the surface of the concrete, and improves the curing effect.

[0028] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

During the maintenance process, the sprayed water is first buffered and adsorbed by the sponge board 603 and then slowly flows out under the action of extrusion, avoiding the direct spraying of water causing cracks and sand on the concrete surface, thereby improving the curing effect.

[0045] The extrusion assembly includes a mounting groove 901 provided on the mounting seat 601, a cam 902 for squeezing and pushing the mounting plate 602 is provided on the mounting groove 901, and a driving assembly for driving the cam 902 is provided on the mounting seat 601; the cam 902 is driven to rotate by the driving assembly, and during the rotation of the cam 902, the cam 902 is caused to abut against the mounting plate 602, pushing the mounting plate 602 to move.

[0046] The driving assembly comprises a support frame 1001 fixed on the mounting base 601, a driving shaft 1002 rotatably connected to the support frame 1001, the cam 902 fixed on the driving shaft 1002, and a first motor 1003 installed on the support frame 1001 and used for driving the driving shaft 1002; through the first motor 1003, the cam 902 on the driving shaft 1002 is driven to rotate.

[0047] The steering assembly comprises a fixed plate 501 fixed on the upper end of the mounting frame 3, a connecting shaft 502 rotatably connected to the fixed plate 501, a connecting plate 503 fixed on the connecting shaft 502, the connecting plate 503 fixed to one side of the U-shaped frame 4, and a second motor 504 installed on the fixed plate 501 and used for driving the connecting shaft 502; through the second motor 504, the connecting shaft 502 is driven to rotate, and in the process of rotation of the connecting shaft 502, the U-shaped frame 4 is driven to adjust the steering through the connecting action of the connecting plate 503.

[0048] In the process of wet curing operation on the large bridge cast-in-place beam plate body 1 after pouring, the U-shaped frame 4 is driven to rotate and adjust through the rotating assembly, the mounting base 601, the mounting plate 602 and the sponge plate 603 are synchronously rotated through the rotation of the U-shaped frame 4, the sponge plate 603 is leveled with the outer side surface of the large bridge cast-in-place beam plate body 1 through the rotation of the sponge plate 603, and the subsequent wet curing operation is facilitated.

[0049] After the steering adjustment, the sponge plate 603 is watered through the watering assembly by moving the moving body 2, the water injected on the sponge plate 603 is adsorbed, the sponge plate 603 abuts against one side of the large bridge cast-in-place beam plate body 1, the mounting plate 602 is extruded through the extruding assembly, and in the process of extrusion, the water adsorbed on the sponge plate 603 flows to the one side surface of the large bridge cast-in-place beam plate body 1 through the extrusion of the mounting plate 602, so that the large bridge cast-in-place beam plate body 1 is wetted and maintained, and in the process of maintenance, the water sprayed and flushed is first buffered and adsorbed by the sponge plate 603 and then slowly flows out through the extrusion, so that the phenomenon of cracks and sanding on the concrete surface caused by direct spraying of water is avoided, and the effect of maintenance is improved.

[0050] As shown in Figures 5 to 8 the inventor has found that, on the basis of the above-mentioned embodiments, in order to avoid relative movement of the sponge plate 603 relative to the large bridge cast-in-place beam plate body 1 during the wet maintenance operation, the following improvements are made:

[0051] The U-shaped frame 4 is provided with a third motor 401 and two guide rails 402 arranged in parallel with the moving direction of the moving body 2, and the two guide rails 402 are slidably connected with sliding blocks 403, the sliding blocks 403 are installed on the side of the mounting seat 601 opposite to the mounting plate 602, and the output end of the third motor 401 is connected with the sliding block 403 through a lead screw.

[0052] By starting the third motor 401 when the sponge plate 603 contacts the large bridge cast-in-place beam plate body 1, the sponge plate 603 is relatively static during contacting the large bridge cast-in-place beam plate body 1, and the relative movement in the wet maintenance path direction is avoided to prevent the surface from being sanding.

[0053] The inventor found that the sponge plate 603 will produce negative pressure effect during reset after extrusion, so that the surface concrete of the large bridge cast-in-place beam plate body 1 is extracted in reverse after being wetted, resulting in sanding of the surface concrete, therefore, based on the above embodiment, the following improvements are made:

[0054] The wet curing assembly further comprises side plates 604 installed on the mounting plate 602 and feeding plates 605 installed on the outside of the sponge plate 603, the feeding plates 605 and the side plates 604 are both provided with two groups, the two groups of side plates 604 are arranged in front of and behind the moving direction of the moving body 2, the side plates 604 are arranged on the side of the feeding plates 605 away from the sponge plate 603, the feeding plates 605 and the side plates 604 are provided with a ratchet structure, the mounting plate 602 is provided with a T-shaped sliding groove 606, the inside of the T-shaped sliding groove 606 is connected with a T-shaped sliding block 607 through a spring, the T-shaped sliding block 607 is fixedly installed on the side plate 604, an electromagnet 608 is installed in the T-shaped sliding groove 606, and an iron block 609 corresponding to the position of the electromagnet 608 is arranged on the T-shaped sliding block 607.

[0055] After the sponge plate 603 contacts the surface of the large bridge cast-in-place beam plate body 1, the ratchet structure will limit the reverse reset of the sponge plate 603 as the sponge plate 603 is continuously extruded to produce water, so that the sponge plate 603 will not be extracted in reverse to extract the water on the surface of the large bridge cast-in-place beam plate body 1, when the sponge plate 603 is separated from the surface of the large bridge cast-in-place beam plate body 1 and is reset without contacting the surface of the large bridge cast-in-place beam plate body 1, the electromagnet 608 is started (magnetic field is generated by power supply) to attract the iron block 609 until the sponge plate 603 drives the feeding plate 605 to reset to the initial state.

[0056] A hinge interconnection large bridge cast-in-place beam plate concrete curing method, the curing steps are as follows:

[0057] Step one, angle alignment

[0058] The second motor 504 is started to drive the connecting shaft 502 to rotate. In the process of rotation of the connecting shaft 502, the U-shaped frame 4 is driven to rotate by the connecting effect of the connecting plate 503. Through the rotation of the U-shaped frame 4, the mounting seat 601, the mounting plate 602 and the sponge plate 603 are synchronously rotated. Through the rotation of the sponge plate 603, the sponge plate 603 is leveled with the outer side surface of the extra-large bridge cast-in-place beam plate body 1.

[0059] Step two, alignment of the starting end

[0060] The mobile vehicle body 2 is placed at one end of the side of the extra-large bridge cast-in-place beam plate body 1, so that the sponge plate 603 is leveled with the starting end of the extra-large bridge cast-in-place beam plate body 1 at one end of the movement direction, and moves along the length direction of the extra-large bridge cast-in-place beam plate body 1.

[0061] Step three, water injection

[0062] Through the pumping effect of the water pump and the connecting effect of the hose 703, the external water is transported towards the connecting pipe 702 and flows out of the sponge plate 603 through each water injection pipe 701, so as to complete the water injection of the sponge plate 603.

[0063] Step four, wet maintenance

[0064] The first motor 1003 is started to drive the cam 902 on the driving shaft 1002 to rotate. In the process of rotation of the cam 902, the cam 902 first abuts against the mounting plate 602, then pushes the mounting plate 602 to move towards the side of the extra-large bridge cast-in-place beam plate body 1, so that the sponge plate 603 abuts against the side of the extra-large bridge cast-in-place beam plate body 1, and then extrudes the sponge plate 603. In the process of extrusion, because the sponge plate 603 abuts against the side surface of the extra-large bridge cast-in-place beam plate body 1, the water absorbed by the sponge plate 603 flows to the side surface of the extra-large bridge cast-in-place beam plate body 1, so as to wet and maintain the extra-large bridge cast-in-place beam plate body 1.

[0065] The third motor 401 is started when the sponge plate 603 contacts the surface of the extra-large bridge cast-in-place beam plate body 1, drives the sliding block 403 to move against the movement direction of the mobile vehicle body 2, and the speed is equal to the speed of the mobile vehicle body 2. When the sponge plate 603 is separated from the surface of the extra-large bridge cast-in-place beam plate body 1, the third motor 401 is reversely rotated to move along the movement direction of the mobile vehicle body 2 to the initial position, and needs to be reset before the sponge plate 603 contacts the surface of the extra-large bridge cast-in-place beam plate body 1 next time.

[0066] Wherein, after the sponge plate 603 contacts the surface of the large bridge cast-in-place beam plate body 1, with the installation plate 602 being continuously pressed by the cam 902, the sponge plate 603 realizes one-way compression through the ratchet structure between the feeding plate 605 and the side plate 604, when the sponge plate 603 is separated from the surface of the large bridge cast-in-place beam plate body 1 and resets without contacting the surface of the large bridge cast-in-place beam plate body 1, the electromagnet 608 opens to attract the iron block 609 until the sponge plate 603 drives the feeding plate 605 to reset to the initial state.

A method for curing cast-in-situ beam slab concrete of a hub interchange super-long bridge, characterized in that, The health maintenance device of claim 6 is used, and the maintenance steps are as follows: Step one, angle alignment Start the second motor (504) to drive the connecting shaft (502) to rotate, in the process of rotating the connecting shaft (502), drive the U-shaped frame (4) to rotate and adjust through the connecting action of the connecting plate (503), drive the mounting base (601), the mounting plate (602) and the sponge plate (603) to rotate synchronously through the rotation of the U-shaped frame (4), and make the sponge plate (603) flush with the outer side surface of the super large bridge cast-in-place beam plate body (1) through the rotation of the sponge plate (603); Step two, starting end alignment Place the moving vehicle body (2) at one end of the side of the super large bridge cast-in-place beam plate body (1), so that the sponge plate (603) is flush with the starting end of the super large bridge cast-in-place beam plate body (1) at the end of the movement direction, and moves along the length direction of the super large bridge cast-in-place beam plate body (1); Step three, water injection Through the pumping action of the water pump and the connecting action of the hose (703), the external water is transported towards the connecting pipe (702) and flows out of the sponge plate (603) through each water injection pipe (701), and the sponge plate (603) is completed water injection; Step four, wet maintenance The first motor (1003) is started to drive the cam (902) on the drive shaft (1002) to rotate. In the process of rotating the cam (902), the cam (902) first abuts against the mounting plate (602), and then pushes the mounting plate (602) to move towards the side of the super-large bridge cast-in-place beam body (1), so that the sponge plate (603) abuts against the side of the super-large bridge cast-in-place beam body (1), and then extrudes the sponge plate (603). In the process of extrusion, because the sponge plate (603) abuts against the side surface of the super-large bridge cast-in-place beam body (1), the water absorbed by the sponge plate (603) flows to the side surface of the super-large bridge cast-in-place beam body (1), so as to wet and maintain the super-large bridge cast-in-place beam body (1); Wherein, the third motor (401) starts to drive the sliding block (403) to move against the moving direction of the moving vehicle body (2) when the sponge plate (603) contacts the surface of the super-large bridge cast-in-place beam body (1), and the speed is equal to the speed of the moving vehicle body (2). When the sponge plate (603) is separated from the surface of the super-large bridge cast-in-place beam body (1), it starts to reverse rotation and moves along the moving direction of the moving vehicle body (2) to the initial position, and needs to be reset before the next sponge plate (603) contacts the surface of the super-large bridge cast-in-place beam body (1). Wherein, after the sponge plate (603) contacts the surface of the super-large bridge cast-in-place beam body (1), the sponge plate (603) is compressed in one direction through the ratchet structure between the feeding plate (605) and the side plate (604) as the mounting plate (602) is continuously extruded by the cam (902). When the sponge plate (603) is separated from the surface of the super-large bridge cast-in-place beam body (1) and is reset without contacting the surface of the super-large bridge cast-in-place beam body (1), the electromagnet (608) is opened to attract the iron block (609) until the sponge plate (603) drives the feeding plate (605) to reset to the initial state.
