Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to a bridge maintenance construction device. Background Art

[0002] Roads are the link for the flow of people and materials in cities, and bridges are an important part of roads. They are important links that help roads cross rivers, lakes and seas, and enable vehicles and pedestrians to pass through mountains and rivers smoothly, making travel more convenient.

[0003] When building a bridge, concrete is usually used for pouring. After pouring, the concrete can gradually solidify and harden mainly because of the hydration of cement, which requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength continues to increase, the bridge concrete must be cured with water after pouring to maintain the humidity required for concrete solidification and avoid the concrete drying too quickly and its strength failing to meet the requirements. The curing period is generally 28 days, that is, the concrete must be cured within 28 days after pouring. During the curing period, the concrete needs to be sprayed with water for wet curing to maintain the moisture inside and on the surface of the concrete, to avoid cracking of the concrete surface, and to avoid damage to the structure caused by inconsistent moisture inside and outside.

[0004] In the past, the usual maintenance process was that a person manually held a sprinkler pipe, the other end of which was connected to a water source, and continuously sprinkled water on the bridge deck with the sprinkler pipe, and the watering operation on the bridge deck was also done manually. In order to improve the efficiency of this purely manual maintenance, a watering truck for maintaining bridges is designed in the prior art. A cart is pushed by a person, and a spray head is provided on the cart. In this way, the efficiency of watering on the bridge deck is greatly improved, such as the application number: CN201721444 Patent document No. 667.6 discloses a bridge maintenance device, the structure of which includes a spray box, a support rod fixedly mounted on the spray box, a support frame with adjustable length arranged on the support rod, a pipeline 1 arranged on the support frame, an electric push rod fixedly mounted inside the support rod, a fixed block fixedly mounted on the piston rod of the electric push rod, a support rod 1 and an oil cylinder hingedly mounted on both sides of the fixed block, a support rod 2 hingedly mounted on the ends of the two support rods 1 away from the fixed block, and pipeline 2 arranged on the support rods 1 and 2. The utility model can spray and maintain the surfaces of both sides of the bridge through the support frame with adjustable length arranged on the support rod, and then spray and maintain the walking surface of the bridge through the cooperation of the support rods 1 and 2 and the pipeline 2 on the support rods 1 and 2.

[0005] Although the above patent can solve the problem of spray blind spots in the process of bridge maintenance, it is the same as its bridge maintenance device, which directly uses water for spray maintenance. The bridge maintenance takes 28 days. The humidity required for the spraying process in the first 1-2 days, the middle ten days and the last few days is different. In addition, the weather changes every day for 28 days. However, when the water is directly used for maintenance, the water is in direct contact with the bridge, which results in water immersion rather than humidity changes. Therefore, it is impossible to perform fine maintenance according to the condition of the bridge. Utility Model Content

[0006] The utility model aims to provide a bridge maintenance construction device to solve the technical problem that the bridge maintenance device in the prior art mentioned above utilizes water for spraying maintenance and it is difficult to achieve refined maintenance during the spraying process.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a bridge maintenance and construction device, including a water tank, walking wheels installed under the water tank and a hand-pushing handle on the water tank, a water outlet pipe is provided at the bottom of the water tank, a control valve is provided on the water outlet pipe, an air compressor is provided on the water tank, a water mist nozzle is connected to the water outlet pipe, the water mist nozzle is provided with a water joint and an air joint, the water joint is connected to the water outlet pipe, and the air joint is connected to the air compressor.

[0008] The beneficial effects of this embodiment are:

[0009] 1. The maintenance of a bridge takes 28 days. The humidity required for the spraying process in the first 1-2 days, the middle ten days and the last few days is different, and the weather changes every day for 28 days. However, if the bridge is maintained directly in water, the water body is in direct contact with the bridge, which results in water immersion rather than humidity changes. Therefore, it is impossible to perform fine maintenance according to the condition of the bridge. The present application utilizes an air compressor in combination with a water mist nozzle, uses a control valve to control the water body, and uses an air compressor to control compressed air for water mist maintenance, thereby avoiding the rough maintenance mode of immersing the bridge in water and better adapting to the humidity changes during the solidification process of the bridge concrete.

[0010] 2. The control valve in this application can control the water flow, and the air compressor controls the compressed air pressure. Therefore, this application can use both to control the size of the sprayed water mist, so that technical workers can adjust the size of the water mist according to the maintenance time period and weather conditions to carry out refined maintenance.

[0011] Furthermore, the height of the water outlet pipe is lower than the bottom of the water tank. The water outlet pipe is lower than the bottom of the water tank, so that water can flow to the water outlet pipe under the action of gravity, and a water pump does not need to be set.

[0012] Furthermore, the bottom of the water tank is a curved surface inclined toward the water outlet pipe, so that the water body can flow toward the water outlet pipe better.

[0013] Furthermore, the water mist nozzle is provided with a water channel and an air channel, the water joint is connected to the water channel, the air joint is connected to the air channel, the air channel is provided with an air channel throat having a diameter smaller than the air channel, the water channel is connected to a mixed flow pipe, and the mixed flow pipe is connected to the air channel throat. The reduced diameter of the air channel throat forms a Venturi structure in the air channel, which can pressurize the compressed air and the water body, and then use the mixed flow pipe to generate suction on the water body in the water channel. Therefore, even if a water pump is not installed on the water body in the water tank, a larger water mist pressure can be achieved by using gravity and the Venturi structure.

[0014] Furthermore, the water tank is provided with a mounting plate, the mounting plate is connected to a horizontal plate, the horizontal plate is connected to a semicircular plate, and a plurality of water mist nozzles are equidistantly mounted on the semicircular plate in the circumferential direction. The semicircular water mist nozzles are distributed during the maintenance process for water mist maintenance, and dead angles are not easy to occur.

[0015] Furthermore, the horizontal plate is connected to the mounting plate by bolts, and the bolt connection method allows the horizontal plate to be disassembled, making it convenient to maintain the water mist nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is further described in detail through specific implementation methods:

[0020] The figure marks in the drawings of the specification include: water tank 1, push handle 11, walking wheel 12, spraying device 13, mounting plate 131, horizontal plate 132, semicircular plate 133, water mist nozzle 134, water channel 1341, water joint 1342, mixed flow pipe 1343, air channel throat 1344, air channel 1345, air joint 1346, ear plate 1347, air compressor 14, water outlet pipe 15, control valve 151.

[0021] Implementation example Figures 1 to 3 As shown: a bridge maintenance construction device includes a water tank 1, which is a rectangular box body welded from stainless steel. However, the bottom surface of the rectangular box body is not a flat plane, but an arc surface inclined toward the connection point of the water outlet pipe 15, so that no matter how much water there is in the water tank 1, it will flow toward the water outlet pipe 15 under the action of gravity and flow out from the water outlet pipe 15.

[0022] The water tank 1 is provided with a push handle 11 welded to the water tank body on the right opposite side. The push handle 11 is a steel pipe structure with a rubber layer on its surface, so that the push handle 11 provides a better feel when the skilled worker pushes it; a walking wheel 12 is installed on the base of the water tank. The walking wheel 12 is an ordinary rubber wheel, which is rotatably connected to the shaft welded to the bottom of the water tank 1 by a bearing.

[0023] An air compressor 14 is arranged above the water tank 1, and a mounting frame is arranged on the upper surface of the water tank 1. The air compressor 14 is fixed on the mounting frame by bolts. The mounting frame transfers the weight of the air compressor 14 to the side wall of the water tank 1, and the upper panel of the packaged water tank 1 will not collapse due to the air compressor.

[0024] A water outlet pipe 15 is provided on the left side of the water tank, the water outlet pipe 15 is connected to the bottom surface of the water tank 1, and a control valve 151 is provided on the water outlet pipe 15. A diverter is provided at the water outlet of the water outlet pipe 15 to divert the water of the water outlet pipe into multiple streams, and the diverter is connected to the spraying device 13 through a soft plastic pipe.

[0025] The spraying device 13 includes a mounting plate 131, which is welded to the side wall of the water tank 1 horizontally, and a threaded hole is opened at the end of the mounting plate 131, and a through hole is also opened in the middle of the horizontal plate 132 fixedly connected to the mounting plate 131, so the horizontal plate 132 is fixed to the mounting plate 131 by bolts, and the two ends of the horizontal plate 132 are welded to the semicircular plate 133 as a whole, and the semicircular plate 133 is a semicircular arc plate, and a plurality of mounting holes are opened at equal angles on the arc surface of the semicircular plate 133. The water mist nozzle 134 passes through the mounting hole on the semicircular plate 133, and the ear plate 1347 on the water mist nozzle 134 is fixed to the semicircular plate 133 by screws to form a Figure 3 The structure shown.

[0026] Water mist nozzle 134 Figure 2 As stated, Figure 2Direction is a description direction, an air channel 1345 and a water channel 1341 are opened inside the water mist nozzle 134, and a water joint 1342 and an air joint 1346 extending out of the water mist nozzle 134 are provided at the right ends of the air channel 1345 and the water channel 1341, and the water joint 1342 and the water channel 1341 are integrated, and the air joint 1346 and the air channel 1345 are integrated, the air channel 1345 passes through the water mist nozzle 134, and the diameter is reduced near the water mist nozzle 134 to form an air channel throat 1344, and a mixed flow channel 1343 connected to the air channel 1345 is vertically opened at the left end of the water channel 1341, and the mixed flow channel 1343 is just connected to the air channel throat 1344. The diameter of the airway throat 1344 is reduced to form a Venturi structure in the airway 1345, which can pressurize the compressed air and water, and then use the mixed flow pipe 1343 to generate suction on the water in the waterway 1341. Therefore, even if a water pump is not installed on the water in the water tank 1, a larger water mist pressure can be achieved by using gravity and the Venturi structure.

[0027] When the water mist nozzle 134 is placed on the semicircular plate 133 Figure 3 After installation as shown, connect the water connector 1342 on the water mist nozzle 134 to the soft plastic tube connected to the diverter on the water outlet pipe 15, and connect the air connector 1346 to the air compressor 14. Therefore, when using the maintenance device of the present application, open the control valve 151, the height of the water outlet pipe 15 is flush with the bottom of the water tank 1, and the water in the water tank 1 flows to the outlet of the water outlet pipe 15 under the action of water pressure. The height of the water mist nozzle 134 is lower than the water outlet pipe 5, so the water flows into different water mist nozzles 134 through the diverter. At the same time, the air compressor 14 is turned on, and the air connector 1346 is connected to the air compressor 14. The compressed air in the air compressor 14 also enters the air passage 1345 in the water mist nozzle 134 through the air connector 1346. Since the air passage runs through the water mist nozzle 134, Compressed air can be sprayed out from the outlet of the airway 1345 of the water mist nozzle 134. When the compressed air passes through the airway throat 1344 during the process of passing through the airway 1345, the diameter suddenly narrows and the fluid flow rate increases rapidly, so that the air pressure at the airway throat 1344 decreases, and the waterway 1341 is connected to the mixed flow channel 1343, and the mixed flow channel 1343 is connected to the airway throat 1344. Therefore, the water in the waterway enters the airway throat 1344 under the dual action of negative pressure and gravity and mixes with the compressed air, and is sprayed out from the outlet of the water mist nozzle 134 to form water mist with a larger coverage area.

[0028] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
