Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a pier robot and a spraying maintenance device. Background Art

[0002] With the country's continuous investment in infrastructure, the construction of urban viaducts and highway bridges in rural and mountainous areas has continued to develop, and bridges and high-rise buildings have continued to increase.

[0003] The pier column plays a supporting role, and the quality of the pier column plays a very important role, and the concrete strength is an important indicator for evaluating the quality of the pier column. The concrete strength is not only related to the raw materials and construction technology, but also has a direct relationship with the maintenance of the concrete. After the pier column is poured, if the concrete is in a dry environment, the water in the concrete evaporates too quickly, the concrete is dehydrated, and the surface will peel off in a flaky or powdery manner; at the same time, when the concrete does not have sufficient strength, the premature evaporation of water will also produce large shrinkage deformation and shrinkage cracks; the hydration inside the concrete cannot be fully carried out due to water loss, causing the crystal structure to relax and the strength to decrease.

[0004] Therefore, after the concrete pouring is completed, the pier body should be covered and sprayed as soon as possible for maintenance and reinforcement. However, the existing spraying methods mostly use spray trucks to spray directly, but this method can only be implemented for piers with relatively low heights. For piers over 50 meters and construction sites with uneven pier bottoms, ordinary spray trucks cannot spray the pier as a whole.

[0005] Therefore, the existing method of spraying and curing piers affects the overall construction quality of the piers due to the above-mentioned technical problems. It can be seen that there is an urgent need to provide a method that can complete the overall spraying and curing of high piers and piers in special terrains, which is a problem that needs to be solved in this field.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0031] At present, for piers over 50 meters in height or on construction sites with uneven bottoms of piers, ordinary spray trucks are unable to spray the piers as a whole. Based on the technical problems existing in the existing spray maintenance of piers, the pier robot and spray maintenance device provided by the present invention can complete the overall spray maintenance of high piers and piers in special terrains by installing a spray system on the pier robot, thereby improving the overall pier construction quality.

[0032] The pier column robot and spray maintenance device provided by the present invention are shown in Figure 1 , which includes a pier robot 100 and a spray maintenance device 200 mounted on the pier robot 100 .

[0033] See also Figure 2 According to the shape of the pier, the main body of the pier robot 100 preferably adopts an octagonal design, and a total of eight groups of power climbing components 110 are arranged, and are connected as a whole through connecting parts 120. It can be mounted on the pier 400, and the eight groups of power climbing components 110 can climb and descend along the pier 400 synchronously.

[0034] The present invention does not limit the structural composition of the power climbing assembly 110. For example, it may include a driving motor and a climbing wheel. The driving motor drives the climbing wheel, and the climbing wheel is driven by the driving motor to drive the fuselage to climb or descend along the pier.

[0035] A spray maintenance device 200 is mounted in the area corresponding to each power climbing assembly 110. The spray maintenance device 200 is mounted in the area corresponding to the power climbing assembly 110 of the pier robot 100 to form an annular spray system. The spray maintenance device 200 is mounted on the pier robot 100 to achieve overall spraying of piers of different types and heights. The spray maintenance device 200 includes an annular spray support system 210 and a spray pipeline system 220.

[0036] The spray bracket system 210 is a mounting bracket for the spray device, see Figure 3 , which includes a support base 211 and a swing assembly disposed on the support base 211. The support base 211 is disposed on the body of the pier robot 100, and the swing assembly is disposed on the support base 211 and can perform relative motion with the pier 400.

[0037] The swing assembly includes a support swing arm 212, a swing arm folding support frame 213 and a spring pin 214. The lower end of the support swing arm 212 is hinged to one end of the folding support frame 213 through a connecting assembly, and the support swing arm 212 can rotate relative to the folding support frame 213 along the connecting assembly, thereby realizing relative movement between the support swing arm 212 and the pier robot 100, thereby controlling the spraying angle of the spray curing device, so that it can accurately spray to the area on the pier 400 that needs to be cured.

[0038] The other end of the folding support frame 213 is fixed to the support seat 211 through a spring pin 214 to fix the swing angle of the support swing arm 212. Figure 4-Figure 5 At the end of the test, the spring pin 214 at the lower end of the folding support arm 212 can be pulled out from the positioning hole of the support seat, so that the support swing arm 212 is folded inward to reduce the size of the equipment.

[0039] The spray pipe system 220 is used to realize the spraying of the spray system, and a plurality of pipe joints are provided corresponding to the spray maintenance device, and the pipe joints respectively include a first connecting component 221 and a spray pipe 222.

[0040] The first connecting component 221 is fixed to the upper end of the supporting swing arm 212. The first connecting component 221 preferably adopts a three-way joint 221. The first end and the second end on both sides are quickly connected with adjacent spray pipes 222 respectively. The spray pipe 222 and the adjacent spray pipes are connected in turn to form an annular body. The third end of the joint is connected to the spray head 225 through a hose, and the spray head 225 is used to spray and maintain the pier 400.

[0041] The connection component in at least one group of the above-mentioned multiple groups of pipe joints is set as a four-way joint 223, three ends of the four-way joint 223 are consistent with the first connection component, and the fourth end is set with a delivery connecting pipe 224. The bottom of the delivery connecting pipe 224 is connected to a water pump, and the curing liquid is transported upward by the water pump. The curing liquid is transported to the adjacent spray pipes 222 through the four-way joint 223, and the pier 400 is sprayed and maintained through the nozzle 225 connected thereto.

[0042] Furthermore, the delivery connecting pipe 224 is provided with a flow control system 226, which can accurately adjust the spray dosage through the control system, save the cost of spraying curing agent, and achieve better curing effect.

[0043] See also Figure 6 The pier robot and spray maintenance device provided in this solution are also equipped with a sealing device 300, which is arranged along the periphery of the pier robot 100 and covers the pier robot 100. It can play a waterproof role during the climbing process of the pier robot 100, thereby protecting the line and structure safety of the pier robot 100 and ensuring the normal operation of the pier robot 100. Figure 7The sealing device 300 includes a sealing cover 310 and a sealing cover support frame 320 .

[0044] The sealing cover support frame 320 is arranged corresponding to each spray maintenance device 200, one end of which is arranged at the upper end of the pier robot 100 connection piece, and the other end is inclined to be arranged at the pier 400 and the end is matched with a roller 350 to be closely arranged with the pier 400.

[0045] The sealing cover 310 is a rectangular waterproof cloth, which surrounds the periphery of the pier robot 100 in an annular direction. The upper end of the sealing cover 310 is fixedly connected to the upper end of the sealing cover support frame 320 by setting an upper elastic band 330, and the lower end is tightened and fixed to the outside of the pier robot 100 by setting a lower elastic band 340, so as to ensure that when the robot spray system is working, it can move along the pier 400 through the roller 350 to avoid the sealing cover support frame 320 and the surface of the pier 400 from scratching, causing damage to the sealing cover 310. The sealing cover 310 also plays a certain waterproof role to prevent the robot structure and electrical circuits from being affected.

[0046] Secondly, the sealing cover support frame 320 is fixedly connected to the upper end of the climbing connection piece of the pier robot 100, and plays the role of supporting the sealing cover 310, which can prevent the sealing cover 310 from fitting against the robot 100, so as to prevent the sealing cover 310 from being rolled into the wheels of the climbing robot during the movement of the robot 100, causing machine operation failure.

[0047] The pier robot and spray maintenance device formed by the above scheme can climb along the pier to a high pier of more than 50 meters by carrying the annular spray system formed by the scheme on the pier robot, so as to realize the spray maintenance of the high pier.

[0048] Secondly, the ring-shaped arrangement of the spray system can achieve uniform spraying of the piers. At the same time, the spraying dosage can be accurately controlled through the control system, saving the cost of spraying curing agents and achieving better maintenance effects.

[0049] In addition, the spray system is equipped with a sealing cover, which can play a waterproof role during the climbing process of the pier robot, thereby protecting the safety of the pier robot's lines and structures and ensuring the normal operation of the pier robot.

[0050] Finally, the spray system and pier robot adopt an integrated and modular design, which can be folded inward when not in operation. At the same time, the spray system adopts quick disassembly and assembly of pipes and joints, and the pipes can be removed and stored when the robot is not in operation, thereby reducing the overall volume of the equipment and facilitating transportation.
