Description

Technical Field

[0001] The invention relates to the technical field of T-beam manufacturing, and in particular to a T-beam maintenance spraying device. Background Art

[0002] T-beam refers to a beam with a T-shaped cross section. The protruding parts on both sides are called flanges, and the middle part is called beam ribs (or webs). It is formed by digging out the concrete in the tensile area of ​​the rectangular beam that does not contribute to the bending strength. In addition to having the same bending strength as the original rectangular beam, it can save concrete, reduce the deadweight of the component, and improve the spanning capacity.

[0003] In the current construction field, in order to improve construction quality, concrete curing is a must-do but difficult task. Since the curing lasts for a long time (usually three to seven days), it requires a large amount of labor and clean water resources. There are many types of existing automatic concrete curing devices, but they are often bulky and have a fixed shape that makes it difficult to apply to structures with undulating or irregular surfaces. Especially for large concrete prefabricated parts such as T-beams in the fields of railways and highways, effective spray curing cannot be performed on T-beams of different sizes. Summary of the invention

[0004] 1. Technical issues to be resolved

[0006] (II) Technical solution

[0007] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0008] The embodiment of the present invention provides a T-beam maintenance spraying equipment, including a spraying assembly and a water-retaining film assembly, the spraying assembly including a movable base that moves along the length direction of the T-beam, a spraying bracket that is arranged at the upper end of the movable base and moves with the movable base, and a spray head that is arranged on the spraying bracket and sprays water on the surface of the T-beam, the movable base has two in total and is respectively arranged on both sides of the T-beam, the spraying bracket includes vertical frames that are respectively vertically arranged at the upper ends of the two movable bases and horizontal frames that are horizontally connected to the tops of the two vertical frames, the circumferential side ends of the vertical frames are rotatably connected with extended rotating rods at even intervals, the spray heads are vertically evenly distributed at the lower side ends of the horizontal frames, the spray heads are fixed to the ends of each of the extended rotating rods away from the vertical frames, the vertical frames and the horizontal frames are wound with water pipes that supply water to the spray heads, and the water-retaining film assembly applies a film to the surface of the T-beam that is sprayed.

[0009] The embodiment of the present invention proposes a T-beam maintenance spraying device. When the maintenance spraying device is used, the movable base is moved to the two sides of the T-beam respectively, so that the two movable bases move synchronously along the length direction of the T-beam. During the movement, water is supplied through the water pipe, so that the nozzles on the vertical frame and the horizontal frame can spray water toward the T-beam, thereby completing the work of spraying the T-beam, and then the surface of the T-beam is coated with a water-retaining coating component, thereby reducing the evaporation of water on the surface of the T-beam, thereby achieving a better maintenance effect. At the same time, in this scheme, the extended rotating rod is evenly rotated and connected at the circumferential side ends of the vertical frame, so that when encountering a special-shaped beam body, the extended rotating rod can be rotated to adjust the distance between the nozzle on the vertical frame and the side surface of the special-shaped beam body, thereby achieving the effect of adjusting according to the shape and size of the beam body, so as to achieve a better spraying effect. At the same time, the extended rotating rod can also be applied to the horizontal frame, thereby adapting to beams with more serious special-shaped structures.

[0010] Optionally, the extended rotating rod is rotatably connected to the vertical frame via a torsion spring, the extended rotating rods on the two vertical frames are opposite to each other under the drive of the torsion spring, the side ends of the extended rotating rods are obliquely provided with a forked rod, the forked rod extends toward one end away from the vertical frame, the end of the forked rod away from the extended rotating rod is rotatably provided with a rubber wheel that rolls and abuts against the side end of the T-beam, the distance between the rubber wheel and the vertical frame is far away from the distance between the nozzle and the vertical frame.

[0011] By rotating the extended rotating rod to the vertical frame through a torsion spring, when the extended rotating rod is only subjected to the force of the torsion spring, the extended rotating rods on both sides of the T-beam are opposite to each other, a forked rod is obliquely arranged at the side end of the extended rotating rod and a rubber wheel is rotatably arranged at the end of the forked rod, so that under the drive of the torsion spring, the rubber wheel will continuously abut against the side end of the T-beam, thereby ensuring that the nozzle on the extended rotating rod can be located at the position closest to the side end face of the T-beam for spraying, providing a better spraying effect without directly contacting the side end of the T-beam.

[0012] Optionally, a plurality of groups of anti-collision wheels are rotatably provided at the ends of the two mobile bases that are close to each other, and the plurality of groups of anti-collision wheels are evenly distributed along the moving direction of the mobile base, and the rotating shafts of the anti-collision wheels are vertical.

[0013] By arranging anti-collision wheels at the ends of the mobile bases that are close to each other, the rotating shaft of the anti-collision wheels is vertical. When the moving route of the mobile base deviates, the anti-collision wheels will touch the side end of the T-beam and roll, thereby continuing to complete the spraying work.

[0014] Optionally, the horizontal frame includes two half frames rotatably connected together, and one end of the two half frames away from each other is rotatably connected to the top of the vertical frame. The top of the vertical frame is provided with positioning grooves evenly spaced circumferentially around the rotating shaft of the half frames, and the half frames are provided with positioning holes on one side of their own rotating shaft, and a positioning column partially inserted into the positioning groove is inserted into the positioning hole.

[0015] By setting the horizontal frame as two half frames that are rotatably connected together, one end of the two half frames is rotatably connected to the top of the vertical frame respectively, and at the same time, the positioning column is inserted into the positioning hole and inserted into the positioning groove for positioning, so that the horizontal frame can change the distance between the two movable bases, thereby making the spray assembly applicable to beams of more sizes and models.

[0016] Optionally, the water-retaining film covering assembly includes a film covering trolley detachably hooked on one side of the mobile base, a film covering bracket arranged on the upper end of the film covering trolley, and a plurality of sections of rolled films rotatably arranged on the film covering bracket.

[0017] After the T-beam surface is sprayed back and forth multiple times by the spray assembly, the two coating trolleys can be directly hooked on one side of the mobile base, so that the coating trolley moves with the mobile base, and then the rolled coating on the coating bracket rotates and adheres the film to the T-beam surface, thereby completing the coating work.

[0018] Optionally, the film coating support includes a vertical side film coating rod, an upper film coating rod with a vertical lower end and an inclined or horizontal top, and a top film coating rod with a vertical lower end and a horizontal upper end. The lower ends of the side film coating rod, the upper film coating rod and the top film coating rod are vertically and detachably connected to the film coating trolley, the side film coating rod is sleeved with the vertical rolled film, the upper film coating rod is rotatably sleeved with the inclined or horizontal rolled film, and the top film coating rod is rotatably sleeved with the horizontal rolled film.

[0019] The rolled film is supported by the side film rod, the upper film rod and the top film rod, so that the rolled film can be suspended on the outside of the T-beam in different directions, thereby facilitating the laminating. At the same time, when laminating T-beams of different shapes, any of the side film rod, the upper film rod and the top film rod can be replaced to ensure smooth laminating work.

[0020] Optionally, the side laminating rod, the upper laminating rod and the top laminating rod are respectively provided with limiting grooves on the outer sides of both ends of the rolled film along their own length directions, and the limiting grooves are rotatably connected with limiting strips that limit the movement of the rolled film along the length directions of the side laminating rods, the upper laminating rod and the top laminating rod.

[0021] By rotating the embedded limit strips on the side laminating rods, the upper laminating rod and the top laminating rod, the limit strips can be rotated to be embedded in the limit grooves when installing the rolled film. When the installation of the rolled film is completed, the limit strips are released, so that the limit strips are rotated and popped out under the drive of the torsion spring, thereby limiting the installed rolled film to ensure that the rolled film will not move along the length direction of the side laminating rods, the upper laminating rod and the top laminating rod during laminating.

[0022] Optionally, a clamping bracket is rotatably arranged at the upper end of the coating trolley in parallel with the side coating rod and the upper coating rod, and the end of the clamping bracket is rotatably connected to a clamping roller for clamping the rolled coating to the surface of the T-beam.

[0023] When the rolled film is coated on the top of the T-beam, under the action of gravity, the film will adhere to the upper end surface of the T-beam under the adhesion of water, and when the side end of the T-beam is coated, the film is vertically laid flat on the side end of the T-beam, or even horizontally laid upwards. As the coating vehicle moves, the film may not be able to adhere. In this solution, a clamping bracket is rotatably set on one side of the side coating rod and the upper coating rod, so that the clamping bracket is rotatably connected to the coating trolley, and the clamping roller is rotatably connected to the clamping bracket, so that during the unfolding process of the rolled film on the side coating rod and the upper coating rod, the clamping bracket can be rotated to the clamping roller to press against the unfolded film, thereby pressing the film to the side end of the T-beam and bonding it through water to complete the coating of the side end of the T-beam.

[0024] Optionally, the movable base and the lower end of the coating trolley are both provided with walking tracks.

[0025] By arranging walking tracks at the lower ends of the mobile base and the coating trolley, the mobile base and the coating trolley can be moved in a complex ground environment to ensure the spraying and maintenance of the T-beam.

[0026] Optionally, the nozzle is in a flat trumpet shape along the length direction of the vertical T-beam.

[0027] By setting the nozzles to be flat trumpet-shaped, the nozzles arranged at even intervals can spray the surface of the T-beam more carefully, avoiding the phenomenon of missing sprays.

[0028] (III) Beneficial effects

[0029] The beneficial effects of the present invention are as follows: when the T-beam maintenance spraying equipment of the present invention is used, the movable base is moved to the two sides of the T-beam respectively, so that the two movable bases move synchronously along the length direction of the T-beam, and water is supplied through the water pipe during the movement, so that the nozzles on the vertical frame and the horizontal frame can spray water toward the T-beam, thereby completing the work of spraying the T-beam, and then the surface of the T-beam is coated with a water-retaining coating component, thereby reducing the evaporation of water on the surface of the T-beam, thereby achieving a better maintenance effect. At the same time, in this scheme, the extended rotating rod is evenly rotated and connected at the circumferential side end of the vertical frame, so that when encountering a special-shaped beam body, the extended rotating rod can be rotated to adjust the distance between the nozzle on the vertical frame and the side surface of the special-shaped beam body, thereby achieving the effect of adjusting according to the shape of the beam body, so as to achieve a better spraying effect.

[0037] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0038] The T-beam maintenance spraying equipment proposed in the embodiment of the present invention, when using the maintenance spraying equipment, the movable base is moved to the two sides of the T-beam respectively, so that the two movable bases move synchronously along the length direction of the T-beam, and water is supplied through the water pipe during the movement, so that the nozzles on the vertical frame and the horizontal frame can spray water toward the T-beam, thereby completing the work of spraying the T-beam, and then the surface of the T-beam is coated with a water-retaining film component, thereby reducing the evaporation of water on the surface of the T-beam, thereby achieving a better maintenance effect. At the same time, in this scheme, the extended rotating rod is evenly rotated and connected at the circumferential side end of the vertical frame, so that when encountering a special-shaped beam body, the extended rotating rod can be rotated to adjust the distance between the nozzle on the vertical frame and the side surface of the special-shaped beam body, thereby achieving the effect of adjusting according to the shape of the beam body, so as to achieve a better spraying effect.

[0039] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] Reference Figures 1 to 5 A T-beam maintenance spraying device includes a spraying component 1 and a water-retaining film component 2. The spraying component 1 includes two mobile bases 11 that move along the length direction of the T-beam, a spraying bracket 12 that is arranged on the upper end of the mobile base 11 and moves with the mobile base 11, and a nozzle 13 that is arranged on the spraying bracket 12 and sprays water on the surface of the T-beam. The water-retaining film component 2 includes a film coating trolley 21 that is detachably hooked on one side of the mobile base 11, a film coating bracket 22 that is arranged on the upper end of the film coating trolley 21, and a multi-segment rolled film 23 that is rotatably arranged on the film coating bracket 22. When using the maintenance spraying equipment, the movable base 11 is moved to both sides of the T-beam respectively, so that the two movable bases 11 move synchronously along the length direction of the T-beam, and water is supplied through the water pipe during the movement, so that the nozzles 13 on the vertical frame 121 and the horizontal frame 122 can spray water toward the T-beam, thereby completing the spraying of the T-beam. After the surface of the T-beam is sprayed back and forth multiple times by the spray assembly 1, the two coating trolleys 21 can be directly hooked on one side of the movable base 11 respectively, so that the coating trolley 21 moves with the movable base 11, and then the rolled coating 23 on the coating bracket 22 rotates and adheres the film to the surface of the T-beam, thereby completing the coating work, and coating the surface of the T-beam through the water-retaining coating assembly 2, thereby reducing the evaporation of water on the surface of the T-beam, thereby achieving a better maintenance effect.

[0041] The spray bracket 12 includes vertical frames 121 vertically welded to the upper ends of the two movable bases 11 and a horizontal frame 122 horizontally connected to the tops of the two vertical frames 121. The side ends of the vertical frames 121 are evenly spaced and rotatably sleeved with extended rotating rods 123. The spray heads 13 are vertically evenly spaced and distributed at the lower side ends of the horizontal frames 122. The spray heads 13 are fixed to the ends of each extended rotating rod 123 away from the vertical frames 121. The spray heads 13 can be supplied with water through water pipes wound around the vertical frames 121 and the horizontal frames 122. The vertical frames 121 and the horizontal frames 122 can also be hollow inside to transport water and supply water to the spray heads 13. When encountering a special-shaped beam, the distance between the nozzle 13 on the vertical frame 121 and the side surface of the special-shaped beam can be adjusted by rotating the extended rotating rod 123, thereby achieving the effect of adjustment according to the shape of the beam to achieve a better spraying effect. At the same time, the extended rotating rod 123 can also be applied to the horizontal frame 122 to adapt to beams with more serious special-shaped structures.

[0042] The nozzles 13 are flat trumpet-shaped along the length direction of the vertical T-beam, so that the nozzles 13 arranged at even intervals can spray the surface of the T-beam more carefully, avoiding the phenomenon of missing sprays.

[0043] The extended rotating rod 123 is rotatably connected to the vertical frame 121 through a torsion spring. The extended rotating rods 123 on the two vertical frames 121 are opposite to each other under the drive of the torsion spring. The side ends of the extended rotating rods 123 are welded with a forked rod 124 in an inclined manner. The forked rod 124 extends to the end away from the vertical frame 121. The end of the forked rod 124 away from the extended rotating rod 123 is rotatably provided with a rubber wheel 125 that rolls and abuts against the side end of the T-beam through a bearing. The distance between the rubber wheel 125 and the vertical frame 121 is far away from the distance between the nozzle 13 and the vertical frame 121. When the extended rotating rod 123 is only subjected to the force of the torsion spring, the extended rotating rods 123 on both sides of the T-beam are opposite to each other, and the forked rod 124 is obliquely set at the side end of the extended rotating rod 123 and the rubber wheel 125 is rotatably set at the end of the forked rod 124, so that under the drive of the torsion spring, the rubber wheel 125 will continue to abut against the side end of the T-beam, thereby ensuring that the nozzle 13 on the extended rotating rod 123 can be located at the position closest to the side end face of the T-beam for spraying, providing a better spraying effect without directly contacting the side end of the T-beam.

[0044] The ends of the two mobile bases 11 that are close to each other are each provided with multiple sets of anti-collision wheels 111 through the rotation of the shaft, and the multiple sets of anti-collision wheels 111 are evenly distributed along the moving direction of the mobile base 11, and the rotation shaft of the anti-collision wheel 111 is vertical. When the moving route of the mobile base 11 deviates, the anti-collision wheel 111 will touch the side end of the T beam and roll, thereby maintaining the normal movement of the mobile base 11 and continuing to complete the spraying work.

[0045] The horizontal frame 122 includes two half frames connected together by rotation through a rotating shaft, and the ends of the two half frames that are away from each other are connected to the top of the vertical frame 121 by rotation. The top of the vertical frame 121 is provided with positioning grooves 1211 evenly spaced in the circumferential direction around the rotating shaft of the half frame, and the half frame is provided with a positioning hole 1221 on one side of its own rotating shaft, and a positioning column 1222 partially inserted into a positioning groove 1211 is inserted into the positioning hole 1221. The positioning column 1222 is inserted into the positioning hole 1221 and inserted into the positioning groove 1211 for positioning, so that the horizontal frame 122 can change the distance between the two movable bases 11, thereby making the spray assembly 1 applicable to beams of more sizes.

[0046] The coating support 22 includes a vertical side coating rod 221, an upper coating rod 222 with a vertical lower end and an inclined or horizontal top, and a top coating rod 223 with a vertical lower end and a horizontal upper end. The lower ends of the side coating rod 221, the upper coating rod 222 and the top coating rod 223 are all vertically and detachably inserted into the coating trolley 21, the side coating rod 221 is sleeved with a vertical rolled film 23, the upper coating rod 222 is rotatably sleeved with an inclined or horizontal rolled film 23, and the top coating rod 223 is rotatably sleeved with a horizontal rolled film 23. The rolled film 23 is supported by the side coating rod 221, the upper coating rod 222 and the top coating rod 223, so that the rolled film 23 can be suspended on the outside of the T-beam in different directions, thereby facilitating coating. At the same time, when coating T-beams of different shapes, any one of the side coating rod 221, the upper coating rod 222 and the top coating can be replaced to ensure smooth coating work.

[0047] The side film-coating rod 221, the upper film-coating rod 222 and the top film-coating rod 223 are respectively provided with limiting grooves 2211 on the outer sides of the two ends of the rolled film 23 along their own length direction, and the limiting clamping strips 2212 for limiting the movement of the rolled film 23 along the length direction of the side film-coating rod 221, the upper film-coating rod 222 and the top film-coating rod 223 are rotatably connected in the limiting grooves 2211 through torsion springs. When the rolled film 23 is installed, the limiting clamping strips 2212 can be rotated to be embedded in the limiting grooves 2211. When the rolled film 23 is installed, the limiting clamping strips 2212 are released, so that the limiting clamping strips 2212 rotate and pop out under the drive of the torsion spring, and then the installed rolled film 23 is limited to ensure that the rolled film 23 will not move along the length direction of the side film-coating rods 221, the upper film-coating rods 222 and the top film-coating rods 223 during film coating.

[0048] A pressing bracket 24 is provided at the upper end of the film coating trolley 21 on one side of the side film coating rod 221 and the upper film coating rod 222 for parallel rotation through a torsion spring, and a pressing roller 241 for pressing the rolled film 23 to the surface of the T beam is rotatably connected to the end of the pressing bracket 24. During the unrolling process of the rolled film 23 on the side film coating rod 221 and the upper film coating rod 222, the pressing bracket 24 can be rotated to press the pressing roller 241 against the unrolled film, thereby pressing the film to the side end of the T beam and bonding it through water to complete the film coating of the side end of the T beam.

[0049] Walking tracks 112 are arranged at the lower ends of the mobile base 11 and the coating trolley 21, so that the mobile base 11 and the coating trolley 21 can move in a complex ground environment to ensure the spraying and maintenance of the T-beam.
