Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of precast box girder spraying maintenance, and particularly to a precast box girder spraying maintenance device and a spraying maintenance method thereof. BACKGROUND

[0002] In the construction of a bridge, a precast beam is widely used. In the process of concrete setting, it is a heat-releasing reaction, which is easy to cause a large amount of internal water to evaporate, and the concrete needs to be maintained.

[0003] In the process of bridge construction, the maintenance of the precast box girder is generally carried out by manual water spraying. The spraying maintenance efficiency is low, and when there are many precast bridges in the construction site, the water spraying on the side of the bridge is easy to be missed, which causes cracks in the bridge and quality problems. In order to solve the problem of low efficiency of manual water spraying maintenance, construction personnel gradually began to use a precast box girder spraying maintenance device for spraying maintenance.

[0004] However, the precast box girder spraying maintenance device in the related art is usually provided with multiple fixed-position water spraying heads for water spraying operation. The spraying area is fixed, and there are often dead angles in the spraying of the precast box girder side wings, which causes uneven spraying and cracks in the precast box girder side wings. In addition, since the positions of the water spraying heads are fixed and cannot be adjusted, the spraying areas of the various nozzles must have overlapping operations, which greatly consumes water and seriously wastes water resources. SUMMARY

[0005] The first object of the present application is to provide a precast box girder spraying maintenance device, which can solve the problems of cracks in the precast box girder side wings caused by dead angles in the precast box girder spraying maintenance device, and great water consumption and serious water resource waste.

[0006] The second object of the present application is to provide a precast box girder spraying maintenance method.

[0007] The first object of the present application is achieved in the following manner:

It should be noted that the spraying water collected in the maintenance water collection part is mixed with impurities such as core stones, gravel, and construction dust, and the maintenance water impurity removal part arranged between the maintenance water collection part and the water storage part can filter and purify the recycled maintenance water entering the water storage part. For example, the maintenance water collection part is a sedimentation tank arranged below the prefabricated box girder, and the impurities such as core stones and gravel having a certain weight will be deposited at the bottom of the maintenance water collection part; when the maintenance water collected in the maintenance water collection part is recycled, the filter screen can filter out the particulate impurities mixed in the maintenance water, thereby avoiding the problem that the particulate impurities block the pipeline between the water storage part and the maintenance water collection part; the adsorption component can adsorb the impurities such as construction dust mixed in the maintenance water, thereby avoiding the problem that the maintenance water entering the pipeline between the water storage part and the maintenance water collection part is too turbid to cause the dirt accumulation on the inner wall of the pipeline.

[0013] After the technical solution is adopted, the following technical effects are achieved: the two mounting holes are symmetrically arranged on both sides of the first sliding groove, and the transmission assembly is arranged as the first and second transmission members and the first and second swinging members, so that when the sliding member slides along the length direction of the first sliding groove, the first swinging member can be driven to rotate around the first pivot hole by the first transmission member, and the first spraying member is further driven to swing; similarly, when the sliding member slides along the length direction of the first sliding groove, the second swinging member can be driven to rotate around the second pivot hole by the second transmission member, and the second spraying member is further driven to swing.

[0014] In the technical solution, when the sliding member slides towards the direction close to the transmission assembly, the included angle between the first spraying member and the second spraying member becomes larger; when the sliding member slides away from the direction close to the transmission assembly, the included angle between the first spraying member and the second spraying member becomes smaller.

[0015] The technical effects achieved by the technical solution are as follows: when the sliding member slides towards the direction close to the transmission assembly, the first transmission member and the second transmission member connected with the sliding member can be driven to rotate relative to the hinge shaft, so that the first swinging member is driven to swing towards the direction away from each other by the first transmission member with the first rotating shaft hole as the axis, and the second swinging member is driven to swing towards the direction away from each other by the second transmission member with the second rotating shaft hole as the axis, so that the included angle between the first spraying member and the second spraying member becomes larger; when the sliding member slides away from the direction close to the transmission assembly, the first transmission member and the second transmission member connected with the sliding member can be driven to rotate relative to the hinge shaft, so that the first swinging member is driven to swing towards the direction close to each other by the first transmission member with the first rotating shaft hole as the axis, and the second swinging member is driven to swing towards the direction close to each other by the second transmission member with the second rotating shaft hole as the axis, so that the included angle between the first spraying member and the second spraying member becomes smaller.

[0016] In the technical solution, the second spraying maintenance part further comprises a driving motor and a power conversion assembly connected between the output shaft of the driving motor and the other end of the sliding member, for converting the rotary motion output by the driving motor into the reciprocating sliding of the sliding member.

[0017] The technical effects achieved by the technical solution are as follows: by arranging the power conversion assembly between the output shaft of the driving motor and the sliding member, the rotary motion output by the driving motor can be converted into the reciprocating sliding of the sliding member by the power conversion assembly.

[0018] In the technical solution, the power conversion assembly comprises a rotating plate connected with the output shaft, and a connecting rod with one end connected with the rotating plate and the other end connected with the other end of the sliding member; when the rotating plate rotates, the sliding member can be driven to reciprocate by the connecting rod.

[0019] The technical effects achieved by the technical solution are as follows: by arranging the power conversion assembly in the form of a rotating plate and a connecting rod, when the output shaft rotates, the rotating plate matched with the output shaft can be driven to rotate, so that the connecting rod and the rotating plate are driven to rotate, and the sliding member is further driven to reciprocate along the length direction of the first sliding groove by the connecting rod.

[0020] In this technical solution, the precast box girder spray curing device further includes: a temperature and humidity detection unit, located on the side of the support unit near the precast box girder, for detecting the temperature and humidity of the surface of the precast box girder and generating temperature and humidity signals; a spray regulating valve, located between the first spray curing unit and the second spray curing unit, for controlling the water output of the precast box girder spray curing device; and an electrical control component, signal-connected to the temperature and humidity detection unit, for controlling the opening degree of the spray regulating valve and the included angle formed between the first spray component and the second spray component according to the temperature and humidity signals.

[0021] The technical effects achieved by adopting this technical solution are as follows: By setting up a temperature and humidity detection unit, the temperature and humidity of the precast box girder surface can be acquired in real time. This allows the generation of corresponding temperature and humidity signals based on the surface temperature and humidity of the precast box girder and the transmission of these signals to the electronic control components. Upon receiving the temperature and humidity signals, the electronic control components can control the opening of the spray regulating valve, adaptively adjust the water output of the first and second spray units, and control the angle between the first and second spray units based on the temperature and humidity signals. This allows for concentrated spraying of areas with higher temperatures and / or lower humidity, thereby improving the spray curing effect.

[0022] In this technical solution, the precast box girder spray curing device further includes: multiple sections of traveling guide rails, which are laid on both sides of the precast box girder along its length.

[0023] The technical effects achieved by adopting this solution are as follows: By laying multiple sections of travel guide rails along the length of the precast box girder on both sides, the travel direction of the precast box girder spray curing device can be guided, avoiding the problem of some areas of the precast box girder not being cured by spray water due to deviation of the travel path of the precast box girder spray curing device. Compared with setting guide wheels between the side end face of the precast box girder and the second support member, laying travel guide rails on both sides of the precast box girder can avoid the problem of incomplete spraying in the area where the guide wheels contact the side end face of the precast box girder; since the volume of the precast box girder is very large, the required length of the travel guide rail is relatively long. Therefore, setting the travel guide rail into segmented multi-section travel guide rails allows for adaptive adjustment of the number of sections of the travel guide rail according to the length of the precast box girder, making it more applicable.

[0024] The second objective of this invention is achieved as follows:

[0026] The technical effects achieved by the technical solution are as follows: the precast box girder spraying maintenance device in any one of the preceding technical solutions can be used, and the same effect can be achieved.

[0027] In the technical solution, the water level monitoring member and the water pump are arranged in the maintenance water collecting part, the precast box girder spraying maintenance method further comprises: acquiring the water level in the maintenance water collecting part in real time through the water level monitoring member; and if the water level is greater than a water level threshold, pumping the maintenance water collected in the maintenance water collecting part into the water storage part through the water pump.

[0028] The technical effects achieved by the technical solution are as follows: the water level monitoring member and the water pump are arranged in the maintenance water collecting part, the water level in the maintenance water collecting part can be acquired in real time through the water level monitoring member, if the water level is greater than a water level threshold, it indicates that the maintenance water recycled in the maintenance water collecting part has accumulated a certain volume, so the maintenance water recycled in the maintenance water collecting part is pumped into the water storage part through the water pump for recycling, thereby improving the utilization rate of the maintenance water and reducing unnecessary water resource consumption.

[0029] In summary, the present application has the following advantages:

[0030] (1) The first spraying maintenance part arranged on the side of the first support member close to the precast box girder can be rotated to fully spray and maintain the top of the precast box girder; the second spraying maintenance part arranged on the side of the walking part close to the precast box girder can be swung to fully spray and maintain the side wings of the precast box girder by adjusting the included angle between the first spraying member and the second spraying member, thereby avoiding the problem of spraying dead angle on the side wings of the precast box girder caused by the fixed position of the spraying head; the maintenance water collecting part arranged below the precast box girder and connected with the pipeline of the water storage part can collect and recycle the spraying water flowing down from the precast box girder, thereby reducing unnecessary water resource consumption during the precast box girder spraying maintenance, and further realizing the recycling of the spraying water.

[0031] (2) By opening the first sliding groove on the spray mounting, the sliding member can reciprocatingly slide along the extension direction of the first sliding groove, and by setting the transmission assembly hinged with the sliding member, the reciprocating sliding of the sliding member can be converted into the reciprocating swing of the first and second spray members, so that sufficient spray maintenance of the side wing of the precast box girder can be realized;

[0032] (3) By setting the temperature and humidity detection part, the temperature and humidity of the surface of the precast box girder can be obtained in real time, so that the corresponding temperature and humidity signal can be generated according to the temperature and humidity of the surface of the precast box girder and sent to the electric control assembly; after receiving the temperature and humidity signal, the electric control assembly can control the opening of the spray regulating valve according to the temperature and humidity signal, adjust the water output of the first and second spray parts adaptively, and control the angle formed between the first and second spray members according to the temperature and humidity signal, so as to concentrate the spray on the area with higher temperature and / or lower humidity, and improve the spray maintenance effect.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0046] [First embodiment]

[0047] Reference is made to Figure 1 , which is a precast box girder spraying maintenance device 100 provided by the first embodiment of the present application. The precast box girder spraying maintenance device 100 is used for spraying maintenance of a precast box girder 200, and in combination with Figures 1 to 9 , the precast box girder spraying maintenance device 100 comprises: a support part comprising a first support 11 and a second support 12 arranged at both ends of the first support 11; a walking part 20 connected to the support part, used for driving the support part to travel along the length of the precast box girder 200; a first spraying maintenance part 30 rotatably arranged at one side of the first support 11 close to the precast box girder 200; a second spraying maintenance part 40 swingably arranged at one side of the walking part 20 close to the box girder; a water storage part 50 connected to the water inlet of the spraying maintenance part through a water supply pipeline; a maintenance water collecting part 60 arranged below the precast box girder 200 and connected to the water inlet of the water storage part 50 through a pipeline; wherein the second spraying maintenance part 40 comprises a first spraying part 441 and a second spraying part 442, and the included angle between the first spraying part 441 and the second spraying part 442 can be adjusted.

[0048] It can be understood that by arranging the first rotatable spraying maintenance part 30 on the side of the first support 11 close to the prefabricated box girder 200, sufficient spraying maintenance can be performed on the top of the prefabricated box girder 200; by arranging the second swingable spraying maintenance part 40 on the side of the walking part 20 close to the prefabricated box girder 200, sufficient spraying maintenance can be performed on the side wings of the prefabricated box girder 200 by adjusting the angle formed between the first spraying part 441 and the second spraying part 442, and the problem of spraying dead angle on the side wings of the prefabricated box girder 200 caused by the fixed position of the spraying head can be avoided; by arranging the maintenance water collecting part 60 connected with the pipeline of the water storage part 50 below the prefabricated box girder 200, the spraying water flowing down from the prefabricated box girder 200 can be collected and recycled, unnecessary water consumption during the spraying maintenance of the prefabricated box girder can be reduced, and the recycling of the spraying water can be realized.

[0049] It should be noted that the spraying water collected at the maintenance water collecting part 60 is mixed with impurities such as core stones, gravel, and construction dust, and by arranging the maintenance water impurity removing part between the maintenance water collecting part 60 and the water storage part 50, the recycled maintenance water entering the water storage part 50 can be filtered and purified. For example, the maintenance water collecting part 60 is a sedimentation tank arranged below the prefabricated box girder 200, and the impurities such as core stones and gravel with a certain weight will be deposited at the bottom of the maintenance water collecting part 60; when the maintenance water collected by the maintenance water collecting part 60 is recycled, the granular impurities mixed in the maintenance water can be filtered out by the filter screen, so as to avoid the pipeline between the water storage part 50 and the maintenance water collecting part 60 being blocked by the granular impurities; the impurities such as construction dust mixed in the maintenance water can be adsorbed by the adsorption assembly, so as to avoid the problem of dirt accumulation on the inner wall of the pipeline caused by the excessive turbidity of the maintenance water entering the pipeline between the water storage part 50 and the maintenance water collecting part 60. For example, a water outlet is formed in the sidewall of the maintenance water collecting part 60, the maintenance water collecting part 60 is connected with the water storage part 50 through the pipeline of the water outlet, and the maintenance water impurity removing part is detachably arranged at the water outlet through the elastic buckle; when the surface of the filter screen is deposited with too many impurities and the adsorption assembly needs to be replaced, the maintenance water impurity removing part can be detached from the water outlet through the elastic buckle for cleaning and replacement.

[0050] Further, the second spraying maintenance part 40 further comprises: a second spraying shell 41, which is internally provided with an accommodating space and is provided with a spraying swing opening 411 and a sliding opening 412 which are in communication with the accommodating space; a spraying mounting part 45, which is provided with a first sliding groove 451; and a transmission assembly 43, wherein the sliding part 42 is connected with the first spraying part 441 and the second spraying part 442 through the transmission assembly 43, and the transmission assembly 43 is used for converting the reciprocating sliding of the sliding part 42 in the first sliding groove 451 into the reciprocating swing of the first spraying part 441 and the second spraying part 442.

[0051] It can be understood that, by opening the first sliding groove 451 on the spray mounting 45, the sliding member 42 can reciprocatingly slide along the extension direction of the first sliding groove 451, and by setting the transmission assembly 43 hinged with the sliding member 42, the reciprocating sliding of the sliding member 42 can be converted into the reciprocating swinging of the first and second spray members 441 and 442, so that the sufficient spray maintenance of the side wing of the precast box girder 200 can be realized.

[0052] Further, the spray mounting 45 further comprises mounting holes 452 symmetrically arranged on both sides of the first sliding groove 451; the transmission assembly 43 comprises symmetrically arranged first and second transmission members 431 and 433 and symmetrically arranged first and second swinging members 432 and 434; one end of the first transmission member 431 is hinged with one end of the sliding member 42, the other end of the first transmission member 431 is hinged with the first swinging member 432, the first swinging member 432 is connected between the first transmission member 431 and the first spray member 441, and a first rotating shaft hole 435 matched with the mounting hole 452 on one side of the first sliding groove 451 is arranged on the first swinging member 432; one end of the second transmission member 433 is hinged with one end of the first transmission member 431, the other end of the second transmission member 433 is hinged with the second swinging member 434, the second swinging member 434 is connected between the second transmission member 433 and the second spray member 442, and a second rotating shaft hole 436 matched with the mounting hole 452 on the other side of the first sliding groove 451 is arranged on the second swinging member 434; when the sliding member 42 reciprocatingly slides along the first sliding groove 451, the first and second swinging members 432 and 434 can be driven to reciprocatingly swing by the first and second transmission members 431 and 433, so as to adjust the included angle formed between the first and second spray members 441 and 442.

[0053] It can be understood that by symmetrically opening two mounting holes 452 on both sides of the first sliding groove 451, and by setting the transmission assembly 43 as symmetric first transmission member 431 and second transmission member 433, first swing member 432 and second swing member 434, the first transmission member 431 and the sliding member 42 are hinged, the first transmission member 431 and the first swing member 432 are hinged, and the first swing member 432 and the mounting hole 452 are matched with the rotating shaft hole, so that when the sliding member 42 slides along the length direction of the first sliding groove 451, the first swing member 432 can be driven to rotate around the first rotating shaft hole 435 by the first transmission member 431, and then the first spray member 441 is swung; similarly, when the sliding member 42 slides along the length direction of the first sliding groove 451, the second swing member 434 can be driven to rotate around the second rotating shaft hole 436 by the second transmission member 433, and then the second spray member 442 is swung.

[0054] Further, when the sliding member 42 slides towards the direction close to the transmission assembly 43, the included angle between the first spray member 441 and the second spray member 442 becomes larger; when the sliding member 42 slides towards the direction close to the transmission assembly 43, the included angle between the first spray member 441 and the second spray member 442 becomes smaller.

[0055] It can be understood that when the sliding member 42 slides towards the direction close to the transmission assembly 43, the first transmission member 431 and the second transmission member 433 hinged with the sliding member 42 can be driven to rotate around the hinge shaft, so that the first swing member 432 can be driven to swing towards the direction away from each other by the first transmission member 431 around the first rotating shaft hole 435, and the second swing member 434 can be driven to swing towards the direction away from each other by the second transmission member 433 around the second rotating shaft hole 436, and then the included angle between the first spray member and the second spray member 442 becomes larger; when the sliding member 42 slides away from the direction close to the transmission assembly 43, the first transmission member 431 and the second transmission member 433 hinged with the sliding member 42 can be driven to rotate around the hinge shaft, so that the first swing member 432 can be driven to swing towards the direction close to each other by the first transmission member 431 around the first rotating shaft hole 435, and the second swing member 434 can be driven to swing towards the direction close to each other by the second transmission member 433 around the second rotating shaft hole 436, and then the included angle between the first spray member and the second spray member 442 becomes smaller.

[0056] Further, the second spray maintenance part 40 further comprises: a driving motor; a power conversion assembly 72 connected between the output shaft of the driving motor and the other end of the sliding member 42, for converting the rotary motion output by the driving motor into the reciprocating sliding of the sliding member 42.

[0057] It can be understood that by arranging the power conversion assembly between the output shaft of the driving motor and the sliding piece 42, the power conversion assembly can be used to convert the rotary motion output by the driving motor into the reciprocating sliding of the sliding piece 42.

[0058] Further, the power conversion assembly 72 comprises a rotating plate 721 connected to the output shaft 71, and a connecting rod 722, one end of the connecting rod 722 being connected to the rotating plate 721 and the other end of the connecting rod 722 being connected to the other end of the sliding piece 42, wherein when the rotating plate 721 rotates, the sliding piece 42 can be driven to reciprocate by the connecting rod 722.

[0059] It can be understood that by arranging the power conversion assembly in the form of a rotating plate and a connecting rod, when the output shaft rotates, the rotating plate matched therewith can be driven to rotate, thereby driving the connecting rod to rotate together with the rotating plate, and further driving the sliding piece 42 to reciprocate along the length direction of the first sliding groove 451 through the connecting rod.

[0060] Further, the precast box girder spraying maintenance device 100 further comprises a temperature and humidity detection part arranged on the support part near one side of the precast box girder 200, for detecting the temperature and humidity of the surface of the precast box girder 200 and generating a temperature and humidity signal; a spraying adjusting valve arranged between the first spraying maintenance part 30 and the second spraying maintenance part 40, for controlling the water output of the precast box girder spraying maintenance device 100; and an electric control assembly signal connected to the temperature and humidity detection part, for controlling the opening degree of the spraying adjusting valve and the included angle between the first spraying part 441 and the second spraying part 442 according to the temperature and humidity signal.

[0061] It can be understood that by arranging the temperature and humidity detection part, the temperature and humidity of the surface of the precast box girder 200 can be obtained in real time, so that the corresponding temperature and humidity signal can be generated according to the temperature and humidity of the surface of the precast box girder 200 and sent to the electric control assembly; after receiving the temperature and humidity signal, the electric control assembly can control the opening degree of the spraying adjusting valve according to the temperature and humidity signal, adaptively adjust the water output of the first spraying part and the second spraying part, and control the included angle between the first spraying part 441 and the second spraying part 442 according to the temperature and humidity signal, so as to concentrate spraying on the area with higher temperature and / or lower humidity and improve the spraying maintenance effect.

[0062] Further, the precast box girder spraying maintenance device 100 further comprises a plurality of walking guide rails laid on both sides of the precast box girder 200 along the length direction of the precast box girder 200.

[0063] Understandably, by laying multiple sections of travel guide rails along the length of both sides of the precast box girder 200, the travel direction of the precast box girder spray curing device 100 can be guided, avoiding the problem of some areas of the precast box girder 200 not being cured by spray water due to deviation in the travel path of the precast box girder spray curing device 100. Compared with setting guide wheels between the side end face of the precast box girder 200 and the second support member 12, laying travel guide rails on both sides of the precast box girder 200 can avoid the problem of incomplete spraying between the guide wheels and the side end face of the precast box girder 200. Since the volume of the precast box girder 200 is very large, the required length of the travel guide rail is relatively long. Therefore, setting the travel guide rails as segmented multi-section travel guide rails can adapt to the length of the precast box girder 200 by adjusting the number of sections of the travel guide rails, making it more applicable.

[0064] [Second Embodiment]

[0065] The second embodiment of the present invention provides a method for spray curing precast box girders. This method uses a precast box girder spray curing device 100 as described in any of the previous technical solutions. The method includes: placing the precast box girder 200 above the curing water collection section 60; laying walking tracks on both sides of the precast box girder 200; obtaining the surface temperature of the precast box girder 200; and controlling the water spray volume of the spray curing device and the included angle formed between the first spray member 441 and the second spray member 442 according to the surface temperature.

[0066] Furthermore, the curing water collection section 60 is equipped with a water level monitoring device and a water pump. The precast box girder spray curing method also includes: obtaining the water level in the curing water collection section 60 in real time through the water level monitoring device; if the water level is greater than the water level threshold, the curing water collected in the curing water collection section 60 is pumped into the water storage section 50 by the water pump.

[0067] Understandably, by installing a water level monitoring device and a water pump in the maintenance water collection section 60, the water level in the maintenance water collection section 60 can be obtained in real time through the water level monitoring device. If the water level is greater than the water level threshold, it means that the maintenance water collected in the maintenance water collection section 60 has accumulated to a certain volume. Therefore, the maintenance water collected in the maintenance water collection section 60 is pumped into the water storage section 50 for recycling, thereby improving the utilization rate of maintenance water and reducing unnecessary water consumption.

[0068] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
