Description

Technical Field

[0001] The invention relates to the technical field of beam pedestal maintenance, and in particular to a box beam pedestal maintenance device and a maintenance method for a heat exchange device. Background Art

[0002] The box girder pedestal is a special facility used to prefabricate box girders. It provides a stable support platform for the production of box girders. Box girder is a common bridge structure, named because of its box-like cross-sectional shape. It has high rigidity and load-bearing capacity and is widely used in various bridge projects.

[0003] The patent with the patent announcement number CN210308372U discloses a spray curing device for prefabricated beams, aiming to provide a spray curing device for prefabricated beams that is easy to use. It includes a beam-making pedestal for supporting prefabricated beams, a water supply main pipe, a plurality of water supply branches, a valve, a top surface curing hose, and a plurality of adjustable rocker arm nozzles; one end of the water supply main pipe is used as a water inlet end, and the other end is closed; the water supply main pipe is arranged in the beam-making pedestal and coincides with the center line of the length direction of the beam-making pedestal; the valve is arranged at the water inlet end of the water supply main pipe, and a groove for accommodating the valve is arranged at the lower part of the beam-making pedestal; a plurality of the water supply branches are arranged at intervals on both sides of the water supply main pipe along the horizontal plane and extend to the outer wall of the beam-making pedestal; the adjustable rocker arm nozzle is arranged at the water outlet end of the water supply branch pipe, and each water supply branch pipe water outlet end is provided with an adjustable rocker arm nozzle; a top surface curing connecting pipe located in the beam-making pedestal is arranged on the water supply main pipe near the valve.

[0004] However, there are still some shortcomings in the device at present: the device can perform water spraying maintenance on the beam pedestal, but during the water spraying maintenance process, the maintenance water pipe sprays water in a fixed position. Therefore, when the pressure supply effect of a single or part of the water pipes is insufficient, it is easy to reduce the water spraying maintenance effect of the beam pedestal. This will easily increase the probability of cracking of the newly cast beam pedestal under the influence of high temperatures in summer in the long run. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a box girder manufacturing pedestal maintenance device and a maintenance method for a heat exchange device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a box beam manufacturing pedestal maintenance device for a heat exchange device, comprising a pedestal, both left and right outer walls of the pedestal are provided with connection components, and two bases are symmetrically arranged on the periphery of the pedestal;

[0007] The tops of the two bases are both provided with anti-drying and cracking devices, the interior of the anti-drying and cracking devices is provided with anti-spillage devices, and the periphery of the anti-spillage devices is provided with anti-adhesion devices;

[0008] The anti-drying and cracking device includes an electric slide rail, the bottom of which is fixedly installed on the top of the base, an L-shaped hollow plate is slidably installed inside the electric slide rail, a U-shaped groove is opened on the top of the L-shaped hollow plate near one end of the pedestal, a water storage component is hinged inside the U-shaped groove of the L-shaped hollow plate, a multi-porous spray gun is fixedly installed on the water storage component near the pedestal, a collecting box is arranged inside the side of the base near the pedestal, a filter plate is fixedly installed on the collecting box near the side of the L-shaped hollow plate, a water supply pump is fixedly installed on the bottom of the inner wall of the collecting box, and a spiral hose is fixedly installed between the top of the water supply pump and the bottom of the water storage component.

[0009] According to the above technical solution, a torsion spring is arranged between the end of the water storage component away from the pedestal and the L-shaped hollow plate, the side of the collection box away from the base is in contact with the outer wall of the pedestal, and the collection box is designed to be inclined. In hot summer weather, the newly cast pedestal needs to be regularly sprayed with water for maintenance. At this time, the base stably supports the electric slide rail, and the electric slide rail is started. The electric slide rail drives the L-shaped hollow plate to reciprocate horizontally inside itself, and the L-shaped hollow plate drives the water storage component to move synchronously. After the water storage component is started, maintenance water is injected into the porous spray gun Source, a porous spray gun sprays the maintenance water source onto the outer wall of the pedestal through multiple water spray holes opened on the outer wall; the excess maintenance water source sprayed onto the outer wall of the pedestal will flow downward along its outer wall and fall into the collection box, and before the water source falls into the collection box, it will first contact with the filter plate, and the filter plate will block and filter the particulate impurities in the water source to prevent the impurities and the water source from entering the collection box simultaneously, and at the same time, the water storage component will pull the spiral hose to deform and extend synchronously when it slides back and forth horizontally, and at the same time, the started water supply pump will continuously input the water into the water storage component through the spiral hose.

[0010] According to the above technical solution, the anti-overflow device includes a U-shaped plate, a plurality of cross bars, an arc block and a resistance plate. The U-shaped plate is fixedly installed on the edge of the water storage component close to the pedestal on one side of the L-shaped hollow plate. The plurality of cross bars are equidistant and fixedly installed on the side of the U-shaped plate close to the L-shaped hollow plate. The arc block is fixedly installed on the side of the U-shaped plate close to one end of the cross bar close to the L-shaped hollow plate. The bottom of the resistance plate is fixedly installed on the top edge of the base. The resistance plate is located on the motion trajectory of the outer wall of the arc block. When the water storage component reciprocates and slides horizontally, it drives the U-shaped plate to move synchronously. The U-shaped plate drives the cross bar to move synchronously. The cross bar drives the arc block to move back and forth horizontally, and the arc block will contact the arc surface at the top of the resistance plate during the process. During the continuous movement of the arc block, the arc block is resisted by the resistance plate and guided by the arc surface, which prompts the arc block to generate an upward force. Through the transmission of force, the U-shaped plate generates a force to push the water storage component to move upward. At this time, the hinge shaft of the water storage component starts to rotate and drives the water storage component to flip upward along the inside of the L-shaped hollow plate. When the water storage component moves upward in an arc trajectory, it drives the multi-hole spray gun to move synchronously. After that, the water storage component is reset by the torsion spring and repeats this process repeatedly.

[0011] According to the above technical solution, the anti-spillage device also includes a transmission plate, a grille slide, a hook plate and a dust reduction mesh plate. The top of the transmission plate is hinged to the side of the U-shaped plate away from the L-shaped hollow plate, the top of the grille slide is hinged to the bottom of the transmission plate, the bottom of the hook plate is hinged to the side of the transmission plate close to the filter plate, the bottom of the dust reduction mesh plate is hinged to the top of the L-shaped hollow plate through a torsion spring, and a square groove is opened inside the L-shaped hollow plate.

[0012] According to the above technical scheme, a torsion spring is arranged between the top of the transmission plate and the U-shaped plate, the grille slide plate contacts the outer wall of the filter plate on the side away from the transmission plate, and the dust reduction screen plate is hinged to the top of the hook-shaped plate on the side close to the filter plate. When the U-shaped plate follows the water storage component to move upward in an arc trajectory, it pushes the transmission plate to move synchronously, and the bottom of the transmission plate is limited by the grille slide plate, causing its own hinge shaft to start rotating. At this time, the transmission plate drives the grille slide plate to slide along the outer wall of the filter plate. At the same time, when the transmission plate follows the U-shaped plate to move horizontally, it will pull the grille slide plate to move synchronously, and when the transmission plate flips upward in an arc trajectory, it drives the hook plate to move synchronously. The top of the hook-shaped plate is limited by the dust reduction screen plate, causing its own hinge shaft to start rotating. At the same time, the dust reduction screen plate is resisted by the hook-shaped plate, causing the hinge shaft between its bottom and the top of the L-shaped hollow plate to start rotating. At this time, the dust reduction screen plate flips in the direction away from the base, and then is reset by the torsion spring.

[0013] The U-shaped frame is hinged on the outer wall of the dust suppression mesh plate, the bottom of the push plate is slidably installed at the top edge of the L-shaped hollow plate, the push plate is hinged inside the U-shaped frame outer wall, the elastic sheet is slidably installed on the top of the L-shaped hollow plate near the bottom of one end of the push plate, and the elastic sheet is fixedly installed on the top of the L-shaped hollow plate away from the bottom of one end of the push plate, the elastic sheet is located on the movement trajectory of the push plate, the top of the hollow rod is fixedly installed on the top of the inner wall of the elastic sheet, and the bottom of the hollow rod is connected to the top of the L-shaped hollow plate. When the dust suppression mesh plate flips away from the pedestal, it drives the U-shaped frame to move synchronously. The bottom of the U-shaped frame is limited by the push plate, causing its own hinge axis to start to rotate. At this time, the U-shaped frame pushes the push plate to slide along the top of the L-shaped hollow plate away from the pedestal. During the sliding process, the push plate resists and pushes the active end of the elastic sheet to move synchronously. At this time, the elastic sheet is deformed and drives the hollow rod to move away from the top of the L-shaped hollow plate. When the push plate is reset, the elastic sheet is quickly reset from the stored force state and drives the hollow rod to knock on the top of the L-shaped hollow plate to generate vibration, and the transmission of force causes the porous spray gun to synchronously generate slight vibration.

[0014] According to the above technical scheme, the anti-adhesion device also includes a number of friction wheels, a reciprocating screw, an arc panel, a limit rod, a fixed rod and a swinging mesh plate. The several friction wheels are symmetrically rotatably installed inside the U-shaped frame, both ends of the reciprocating screw are fixedly installed on the side of the friction wheel close to the center of the U-shaped frame, the bottom end of the arc panel passes through and is movably installed on the outer wall of the reciprocating screw, both ends of the limit rod are fixedly installed on the inner wall of the U-shaped frame, both ends of the fixed rod are fixedly installed inside the square groove of the dust reduction mesh plate, and the inside of the swinging mesh plate is penetrated by a torsion spring and hinged at the outer wall of the fixed rod.

[0015] The U-shaped frame moves in a direction away from the pedestal, driving the friction wheel to synchronously slide and rub along the top of the L-shaped hollow plate. The friction wheel begins to rotate along the inside of the U-shaped frame through friction force. When the friction wheel rotates, it drives the reciprocating screw rod to rotate. When the reciprocating screw rod rotates, it limits the built-in block of the arc panel through the reciprocating spiral groove on its own outer wall, which can drive the arc panel to slide reciprocatingly horizontally along the limit rod. During the sliding process of the arc panel, it will resist the arc surface of one end of the swinging screen plate close to the push plate. As the arc panel resists, the swinging screen plate generates a rotational force. At this time, the swinging screen plate will rotate along the outer wall of the fixed rod. When the swinging screen plate rotates to an inclined angle, it is convenient for the arc panel to pass over a single swinging screen plate. At this time, the swinging screen plate will swing back and forth during the process of resetting by the torsion spring.

[0016] A maintenance method for a box girder manufacturing pedestal maintenance device for a heat exchange device, comprising the following steps:

[0017] S1: In hot summer weather, the newly cast pedestal needs to be regularly sprayed with water for maintenance. At this time, the base provides stable support for the electric slide rail. The electric slide rail is started, and the electric slide rail drives the L-shaped hollow plate to reciprocate horizontally inside itself, and the L-shaped hollow plate drives the water storage component to move synchronously;

[0018] S2: After the water storage component is started, the maintenance water source is injected into the porous spray gun, and the porous spray gun sprays the maintenance water source onto the outer wall of the pedestal through multiple water spray holes opened on the outer wall;

[0019] S3: The excess maintenance water sprayed on the outer wall of the pedestal will flow down along the outer wall and fall into the collection box. Before the water falls into the collection box, it will first contact the filter plate, which will block and filter the particulate impurities in the water to prevent the impurities and the water from entering the collection box simultaneously.

[0020] S4: When the water storage component slides back and forth horizontally, the spiral hose is pulled to deform and extend synchronously. At the same time, the water supply pump is started and continuously inputs water into the water storage component through the spiral hose.

[0021] The present invention provides a box beam manufacturing pedestal maintenance device and maintenance method for a heat exchange device, which has the following beneficial effects:

[0022] (1) The present invention adopts the setting of the anti-drying and cracking device, and cooperates with the electric slide rail, L-shaped hollow plate, water storage component, porous spray gun, collection box, filter plate, water supply pump and spiral hose. The electric slide rail effectively expands the range of movement of the L-shaped hollow plate, that is, effectively expands the spraying coverage of the pedestal by the porous spray gun, which is different from the traditional fixed-position water spraying, avoids the insufficient supply pressure of a single or multiple porous spray guns, resulting in reduced water spraying maintenance effect on the pedestal, and prevents the newly cast pedestal from increasing the probability of cracking under the influence of high temperature in summer; and realizes the recycling of maintenance water sources to reduce the loss of water resources, and ensures that the maintenance work can be carried out continuously without interruption. The filter plate effectively prevents particulate impurities from invading the water supply pump to increase its use loss, and at the same time avoids particulate matter clogging the pipe mouth, resulting in insufficient pressurization of the porous spray gun, thereby reducing the spraying distance, resulting in reduced maintenance effect.

[0023] (2) The present invention realizes the continuous change of the spraying angle of the porous spray gun by setting an anti-overflow device through the coordination of a water storage component, a U-shaped plate, a cross bar, an arc block, a resistance plate, a transmission plate, a grille slide plate, a hook plate and a dust suppression mesh plate, so as to enable the porous spray gun to maintain a wider range of the pedestal within the same time, and prevent the porous spray gun from spraying horizontally for a long time, making it difficult to maintain the corners and gaps of the pedestal, thereby shortening the maintenance time and improving the comprehensiveness of the pedestal maintenance; and expanding the activity range of the grille slide plate, relying on the grille slide plate to clean the impurity particles accumulated on the surface of the filter plate in time, preventing the filter holes of the filter plate from being blocked and thus slowing down the water collection efficiency, and avoiding the waste caused by the excessive evaporation of water at high temperature. At the same time, the dust suppression mesh plate absorbs the dust raised when the pedestal is maintained during the continuous swinging process, and avoids the dust from spreading everywhere and aggravating the environmental pollution.

[0024] (3) The present invention sets an anti-adhesion device, and cooperates with a dust-reducing mesh plate, a U-shaped frame, a push plate, an elastic sheet, a hollow rod, a friction wheel, a reciprocating screw rod, an arc panel, a limit rod, a fixed rod and a swinging mesh plate. After the maintenance work is completed, the residual water source at the nozzle of the porous spray gun is quickly shaken off by the vibration force, so as to avoid the residual water source hanging at the nozzle of the porous spray gun for a long time, and prevent external dust from continuously adhering to the nozzle of the porous spray gun when it is stationary, causing blockage and erosion, thereby avoiding shortening the service life of the porous spray gun and increasing the difficulty of maintenance; at the same time, the reciprocating swing of the swinging mesh plate is used to swing and guide the dust floating toward the dust-reducing mesh plate, so as to improve the uniformity of the dust adsorption of the dust-reducing mesh plate, and prevent the dust-reducing mesh plate from being locally saturated, thereby increasing the possibility of secondary dust dispersion. At the same time, the reciprocating swing of the swinging mesh plate disturbs the floating dust to avoid the dust falling vertically and adhering to the nozzle of the porous spray gun.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figure 1-Figure 8 , one embodiment of the present invention is: a box beam manufacturing pedestal maintenance device for a heat exchange device, comprising a pedestal 1, both left and right outer walls of the pedestal 1 are provided with connection components 2, and two bases 3 are symmetrically provided on the periphery of the pedestal 1;

[0036] The tops of the two bases 3 are both provided with anti-drying crack devices 4, the interior of the anti-drying crack devices 4 is provided with anti-spillage devices 5, and the periphery of the anti-spillage devices 5 is provided with anti-adhesion devices 6;

[0037] The anti-drying and cracking device 4 includes an electric slide rail 41, the bottom of the electric slide rail 41 is fixedly installed on the top of the base 3, an L-shaped hollow plate 42 is slidably installed inside the electric slide rail 41, a U-shaped groove is opened on the top of the L-shaped hollow plate 42 near the end of the pedestal 1, a water storage component 43 is hinged inside the U-shaped groove of the L-shaped hollow plate 42, a multi-porous spray gun 44 is fixedly installed on the side of the water storage component 43 near the pedestal 1, a collecting box 45 is arranged inside the side of the base 3 near the pedestal 1, a filter plate 46 is fixedly installed on the side of the collecting box 45 near the side of the L-shaped hollow plate 42, a water supply pump 47 is fixedly installed on the bottom of the inner wall of the collecting box 45, and a spiral hose 48 is fixedly installed between the top of the water supply pump 47 and the bottom of the water storage component 43.

[0038] A torsion spring is arranged between the end of the water storage component 43 away from the pedestal 1 and the L-shaped hollow plate 42, and the collecting box 45 is in contact with the outer wall of the pedestal 1 on the side away from the base 3, and the collecting box 45 is inclined. Through the above cooperation, the electric slide rail 41 is relied on to effectively expand the range of movement of the L-shaped hollow plate 42, that is, the spraying coverage of the pedestal 1 by the porous spray gun 44 is effectively expanded, which is different from the traditional fixed-position water spraying, and avoids insufficient pressure supply of a single or multiple porous spray guns 44, resulting in reduced water spraying maintenance effect on the pedestal 1, and prevents the newly cast pedestal 1 from cracking under the influence of high temperature in summer. The above cooperation realizes the recycling of maintenance water sources to reduce the loss of water resources, and ensures that the maintenance work can be carried out continuously without interruption, and the filter plate 46 effectively prevents particulate impurities from invading the water supply pump 47 to increase its use loss, and at the same time avoids particulate matter clogging the pipe mouth, resulting in insufficient pressurization of the porous spray gun 44, thereby reducing the spraying distance, resulting in reduced maintenance effect.

[0039] During use, in hot summer weather, the newly cast pedestal 1 needs to be regularly sprayed with water for maintenance. At this time, the base 3 stably supports the electric slide rail 41, and the electric slide rail 41 is started. The electric slide rail 41 drives the L-shaped hollow plate 42 to perform reciprocating horizontal movement inside itself, and the L-shaped hollow plate 42 drives the water storage component 43 to move synchronously. After the water storage component 43 is started, the maintenance water source is injected into the porous spray gun 44, and the porous spray gun 44 sprays the maintenance water source to the outer wall of the pedestal 1 through multiple water spray holes opened on the outer wall. Through the above cooperation, the electric slide rail 41 is relied on to effectively expand the activity range of the L-shaped hollow plate 42, that is, the spraying coverage range of the porous spray gun 44 on the pedestal 1 is effectively expanded, which is different from the traditional fixed-position water spraying, and avoids the insufficient supply pressure of a single or multiple porous spray guns 44, resulting in a reduced water spray maintenance effect on the pedestal 1, and preventing the newly cast pedestal 1 from cracking under the influence of high temperature in summer. In addition, the excess maintenance water sprayed on the outer wall of the pedestal 1 will flow downward along its outer wall and fall into the collection box 45. Before the water falls into the collection box 45, it first contacts the filter plate 46. The filter plate 46 blocks and filters the particulate impurities in the water to prevent the impurities and the water from entering the collection box 45 simultaneously. At the same time, the water storage component 43 pulls the spiral hose 48 to deform and extend synchronously when sliding back and forth horizontally. At the same time, the started water supply pump 47 continuously inputs the water storage component 43 through the spiral hose 48. Through the above cooperation, the maintenance water source is recycled to reduce the loss of water resources, and it is ensured that the maintenance work can be carried out continuously without interruption. The filter plate 46 effectively prevents particulate impurities from invading the water supply pump 47 to increase its use loss, and at the same time prevents particulate matter from clogging the pipe mouth, resulting in insufficient pressurization of the porous spray gun 44, thereby reducing the spraying distance and reducing the maintenance effect.

[0040] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-overflow device 5;

[0041] The anti-overflow device 5 includes a U-shaped plate 51, a plurality of cross bars 52, an arc block 53 and a contact plate 54. The U-shaped plate 51 is fixedly installed on the edge of the water storage component 43 near the pedestal 1 on one side close to the L-shaped hollow plate 42. The plurality of cross bars 52 are equidistant and fixedly installed on the side of the U-shaped plate 51 close to the L-shaped hollow plate 42. The arc block 53 is fixedly installed on the side close to the U-shaped plate 51 on one end of the cross bar 52 close to the L-shaped hollow plate 42. The bottom of the contact plate 54 is fixedly installed on the top edge of the base 3. The contact plate 54 is located on the movement trajectory of the outer wall of the arc block 53. Through the above coordination, the spraying angle of the porous spray gun 44 is continuously changed, that is, the porous spray gun 44 is prompted to have a wider maintenance range of the pedestal 1 within the same length of time, and prevents the porous spray gun 44 from spraying horizontally for a long time, making it difficult to maintain the corners and gaps of the pedestal 1, shortening the time required for maintenance while improving the comprehensiveness of the maintenance of the pedestal 1.

[0042] The anti-overflow device 5 also includes a transmission plate 55, a grille slide 56, a hook plate 57 and a dust suppression mesh plate 58. The top of the transmission plate 55 is hinged to the side of the U-shaped plate 51 away from the L-shaped hollow plate 42, the top of the grille slide 56 is hinged to the bottom of the transmission plate 55, the bottom of the hook plate 57 is hinged to the side of the transmission plate 55 close to the filter plate 46, and the bottom of the dust suppression mesh plate 58 is hinged to the top of the L-shaped hollow plate 42 through a torsion spring, and a square groove is opened inside the L-shaped hollow plate 42.

[0043] A torsion spring is arranged between the top of the transmission plate 55 and the U-shaped plate 51, the grille plate 56 is in contact with the outer wall of the filter plate 46 on the side away from the transmission plate 55, and the dust reduction mesh plate 58 is hinged on the top of the hook-shaped plate 57 on the side close to the filter plate 46. The above cooperation expands the range of motion of the grille plate 56, and the grille plate 56 is relied on to clean the impurity particles accumulated on the surface of the filter plate 46 in time to prevent the filter holes of the filter plate 46 from being blocked, thereby slowing down the collection efficiency of the water source, and avoiding the waste caused by excessive evaporation of water source under high temperature. At the same time, the dust reduction mesh plate 58 is constantly swinging to absorb the dust raised during the maintenance of the pedestal 1 to prevent the dust from spreading everywhere and aggravating the environmental pollution.

[0044] When in use, the water storage component 43 drives the U-shaped plate 51 to move synchronously when it slides back and forth horizontally, and the U-shaped plate 51 drives the cross bar 52 to move synchronously. The cross bar 52 drives the arc block 53 to move back and forth horizontally, and the arc block 53 contacts the top arc surface of the resistance plate 54 during the continuous movement of the arc block 53, which is resisted by the resistance plate 54 and guided by the arc surface, so that the arc block 53 generates an upward force. Through the transmission of force, the U-shaped plate 51 generates a force to push the water storage component 43 upward. At this time, the hinge shaft of the water storage component 43 starts to rotate and drives the water storage component 43 along the L-shaped hollow plate 4 2 is turned upward inside, and when the water storage component 43 moves upward in an arc trajectory, it drives the porous spray gun 44 to move synchronously, and then the water storage component 43 is reset by the torsion spring and reciprocates in this way. Through the above cooperation, the spraying angle of the porous spray gun 44 is continuously changed, that is, the porous spray gun 44 is prompted to maintain a wider range of the pedestal 1 within the same time, and the porous spray gun 44 is prevented from spraying horizontally for a long time, which makes it difficult to maintain the corners and gaps of the pedestal 1, shortening the maintenance time and improving the comprehensiveness of the maintenance of the pedestal 1; when the U-shaped plate 51 follows the water storage component 43 to move upward in an arc trajectory The transmission plate 55 is pushed to move synchronously. The bottom of the transmission plate 55 is limited by the grille slide plate 56 to cause its own hinge shaft to start rotating. At this time, the transmission plate 55 drives the grille slide plate 56 to slide along the outer wall of the filter plate 46. At the same time, when the transmission plate 55 follows the U-shaped plate 51 to move horizontally, it will pull the grille slide plate 56 to move synchronously. When the transmission plate 55 turns upward in an arc trajectory, it drives the hook plate 57 to move synchronously. The top of the hook plate 57 is limited by the dust suppression mesh plate 58 to cause its own hinge shaft to start rotating. At the same time, the dust suppression mesh plate 58 is resisted by the hook plate 57 to cause The hinge shaft between its bottom and the top of the L-shaped hollow plate 42 begins to rotate. At this time, the dust suppression mesh plate 58 flips away from the base 1 and is then reset by the torsion spring. The above cooperation expands the range of motion of the grille slide plate 56, and the grille slide plate 56 is used to clean the impurity particles accumulated on the surface of the filter plate 46 in time to prevent the filter holes of the filter plate 46 from being blocked, thereby slowing down the collection efficiency of the water source and avoiding waste caused by excessive evaporation of water at high temperature. At the same time, the dust suppression mesh plate 58 is constantly swinging to absorb the dust raised during the maintenance of the base 1 to prevent the dust from spreading everywhere and aggravating the environmental pollution.

[0045] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-adhesion device 6;

[0046] The anti-adhesion device 6 includes a U-shaped frame 61, a push plate 62, an elastic sheet 63 and a hollow rod 64. The top of the U-shaped frame 61 is hinged at the outer wall of the dust suppression mesh plate 58, the bottom of the push plate 62 is slidably installed at the top edge of the L-shaped hollow plate 42, the push plate 62 is hinged inside the U-shaped frame 61 The outer wall, the elastic sheet 63 close to the bottom of one end of the push plate 62 is slidably installed on the top of the L-shaped hollow plate 42, and the bottom of the elastic sheet 63 away from the push plate 62 is fixedly installed on the top of the L-shaped hollow plate 42, and the elastic sheet 63 is located at the top of the push plate 62. On the track, the top of the hollow rod 64 is fixedly mounted on the top of the inner wall of the elastic sheet 63, and the bottom of the hollow rod 64 and the top of the L-shaped hollow plate 42 cooperate to rely on the vibration force to quickly shake off the residual water at the nozzle of the porous spray gun 44 after the maintenance work is completed, so as to avoid the residual water from staying at the nozzle of the porous spray gun 44 for a long time, and prevent external dust from continuously adhering to the nozzle of the porous spray gun 44 when the porous spray gun 44 is stationary, causing blockage and erosion, thereby avoiding shortening the service life of the porous spray gun 44 and increasing the difficulty of maintenance.

[0047] The anti-adhesion device 6 also includes a plurality of friction wheels 65, a reciprocating screw rod 66, an arc panel 67, a limit rod 68, a fixed rod 69 and a swinging mesh plate 610. The plurality of friction wheels 65 are symmetrically rotatably installed inside the U-shaped frame 61, both ends of the reciprocating screw rod 66 are fixedly installed on the side of the friction wheel 65 close to the center of the U-shaped frame 61, the bottom end of the arc panel 67 passes through the inside and is movably installed on the outer wall of the reciprocating screw rod 66, both ends of the limit rod 68 are fixedly installed on the inner wall of the U-shaped frame 61, both ends of the fixed rod 69 are fixedly installed inside the square groove of the dust reduction mesh plate 58, and the inside of the swinging mesh plate 610 is penetrated by a torsion spring and hinged on the outer wall of the fixed rod 69.

[0048] The outer wall of the friction wheel 65 contacts the top of the L-shaped hollow plate 42, the outer wall of the limit rod 68 movably passes through the interior of the arc panel 67, and the swinging mesh plate 610 is located on the movement trajectory of the arc panel 67 near one end of the reciprocating screw rod 66. Through the above coordination, the reciprocating swing of the swinging mesh plate 610 will swing and guide the dust floating toward the dust reduction mesh plate 58, thereby improving the uniformity of the dust reduction mesh plate 58 on dust adsorption, preventing the dust reduction mesh plate 58 from being locally saturated, thereby increasing the possibility of secondary dust dispersion. At the same time, the reciprocating swing of the swinging mesh plate 610 disturbs the floating dust back and forth, preventing the dust from falling vertically and adhering to the nozzle of the porous spray gun 44.

[0049] When in use, the dust suppression screen plate 58 flips away from the pedestal 1 and drives the U-shaped frame 61 to move synchronously. The bottom of the U-shaped frame 61 is limited by the push plate 62, causing its own hinge axis to start to rotate. At this time, the U-shaped frame 61 pushes the push plate 62 to slide along the top of the L-shaped hollow plate 42 away from the pedestal 1. During the sliding process of the push plate 62, it resists and drives the active end of the elastic sheet 63 to move synchronously. At this time, the elastic sheet 63 is deformed and drives the hollow rod 64 to move away from the top of the L-shaped hollow plate 42. When the push plate 62 is reset, the elastic sheet 63 is quickly reset from the stored force state and drives the hollow rod 64 The top of the L-shaped hollow plate 42 is struck to generate vibration, and the porous spray gun 44 is caused to generate slight vibration synchronously through the force transmission. Through the above cooperation, the residual water source at the nozzle of the porous spray gun 44 is quickly shaken off by the vibration force after the maintenance work is completed, so as to avoid the residual water source hanging at the nozzle of the porous spray gun 44 for a long time, and to prevent external dust from continuously adhering to the nozzle of the porous spray gun 44 when the porous spray gun 44 is stationary, causing blockage and erosion, thereby avoiding shortening the service life of the porous spray gun 44 and increasing the difficulty of maintenance; when the U-shaped frame 61 moves away from the pedestal 1, it drives the friction wheel 65 to move along the L-shaped hollow plate 4 2 The top part is synchronously sliding and rubbing, and the friction wheel 65 starts to rotate along the inside of the U-shaped frame 61 through the friction force. When the friction wheel 65 rotates, it drives the reciprocating screw rod 66 to rotate. When the reciprocating screw rod 66 rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the arc panel 67, and can drive the arc panel 67 to slide back and forth horizontally along the limit rod 68. During the sliding process of the arc panel 67, it will resist the arc surface of the swinging mesh plate 610 close to the push plate 62. With the resistance of the arc panel 67, the swinging mesh plate 610 is prompted to generate a rotational force. At this time, the swinging mesh plate 610 will rotate along the outer wall of the fixed rod 69, and the swinging mesh plate 610 will rotate. When the mesh plate 610 is rotated to an inclined angle, it is convenient for the arc panel 67 to pass over a single swinging mesh plate 610. At this time, the swinging mesh plate 610 will swing back and forth during the process of resetting through the torsion spring. Through the above coordination, the reciprocating swing of the swinging mesh plate 610 will swing and guide the dust floating toward the dust reduction mesh plate 58, thereby improving the uniformity of the dust adsorption of the dust reduction mesh plate 58, preventing the dust reduction mesh plate 58 from being locally saturated, thereby increasing the possibility of secondary dust dispersion. At the same time, the reciprocating swing of the swinging mesh plate 610 disturbs the floating dust back and forth, preventing the dust from falling vertically and adhering to the nozzle of the porous spray gun 44.

[0050] A maintenance method for a box girder manufacturing pedestal maintenance device for a heat exchange device, comprising the following steps:

[0051] S1: In hot summer weather, the newly cast pedestal 1 needs to be regularly sprayed with water for maintenance. At this time, the base 3 stably supports the electric slide rail 41, and the electric slide rail 41 is started. The electric slide rail 41 drives the L-shaped hollow plate 42 to reciprocate horizontally inside itself, and the L-shaped hollow plate 42 drives the water storage component 43 to move synchronously;

[0052] S2: After the water storage component 43 is started, the maintenance water source is injected into the porous spray gun 44, and the porous spray gun 44 sprays the maintenance water source onto the outer wall of the pedestal 1 through a plurality of water spray holes provided on the outer wall;

[0053] S3: The excess maintenance water sprayed onto the outer wall of the pedestal 1 will flow down along the outer wall and fall into the collection box 45. Before the water falls into the collection box 45, it will first contact the filter plate 46. The filter plate 46 blocks and filters the particulate impurities in the water, preventing the impurities and the water from entering the collection box 45 simultaneously.

[0054] S4: When the water storage component 43 slides back and forth horizontally, it pulls the spiral hose 48 to deform and extend synchronously. At the same time, the water supply pump 47 is started and continuously inputs water into the water storage component 43 through the spiral hose 48.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
