[0026] The shape of the support device 3 itself is adjustable, that is, the shape of the support device 3 can be changed according to the actual object to be sprayed. For example, when the cross-section of the object to be sprayed is rectangular, the support device 3 can be formed into a rectangle; when spraying one side of the object to be sprayed, the support device 3 can be in the shape of a long strip.

[0027] The spray mechanism 5 is disposed on the supporting device 3 , and is used to spray water to the object to be sprayed, wherein the object to be sprayed may be a concrete column, a wall surface, etc., and this embodiment does not impose any limitation on this.

In addition, the shape of the supporting device 3 itself is adjustable, and the shape can be changed according to the needs of the sprayed object, so as to better spray the sprayed object, simplify the spraying process, improve the construction efficiency, and solve the problem in the prior art that spraying water on concrete columns by holding a water pipe nozzle easily reduces the construction efficiency.

[0029] See also Figures 1 to 4 In the above embodiment, the support device 3 includes: a support rod 31, two rotating rods 32, a first adjusting rod 33, a second adjusting rod 34, a locking mechanism 35 and a limiting mechanism 36. Among them, the support rod 31 is connected to the position adjustment mechanism 4, and the connection is a fixed connection.

[0030] The first ends of the two rotating rods 32 correspond to the two ends of the support rod 31 one by one, and the first end of each rotating rod 32 is rotatably connected to the corresponding end of the support rod 31, so that the two rotating rods 32 can rotate relative to the support rod 31. The second end of one of the rotating rods 32 is rotatably connected to the first end of the first adjustment rod 33, and the second end of the other rotating rod 32 is rotatably connected to the first end of the second adjustment rod 34. The second end of the first adjustment rod 33 and the second end of the second adjustment rod 34 are locked by a locking mechanism 35, that is, the locking mechanism 35 locks the second end of the first adjustment rod 33 and the second end of the second adjustment rod 34 together, so that the first adjustment rod 33 and the second adjustment rod 34 are connected together, and the overall length of the first adjustment rod 33 and the second adjustment rod 34 after being connected is equal to the length of the support rod 31, and the first adjustment rod 33 and the second adjustment rod 34 are parallel to the support rod 31 after being connected, and the two rotating rods 32 are also parallel. After the locking mechanism 35 connects the first adjustment rod 33 and the second adjustment rod 34, the support rod 31, the two rotating rods 32, the first adjustment rod 33 and the second adjustment rod 34 are arranged to form a rectangular structure, and the cross section of the support device 3 is rectangular. In this way, the object to be sprayed can be placed in the rectangular structure of the support device 3, and the spraying mechanism 5 can spray the object to be sprayed around the circle at the same time, thereby improving the spraying speed and spraying efficiency.

[0031] Both ends of the inner side of each rotating rod 32 are provided with L-shaped limiting blocks 7, the inner side of the rotating rod 32 refers to the inside of the rectangular structure, and the limiting blocks 7 are in a right angle shape. When the support rod 31, the two rotating rods 32, the first adjusting rod 33 and the second adjusting rod 34 are arranged to form a rectangular structure, the inner side of the support rod 31, the inner side of the first adjusting rod 33 and the inner side of the second adjusting rod 34 are all in contact with the corresponding limiting blocks 7, that is, the inner side of the support rod 31 is in contact with the limiting blocks 7 of the two rotating rods 32, the inner side of the first adjusting rod 33 is in contact with the limiting blocks 7 at the connected rotating rod 32, and the inner side of the second adjusting rod 34 is in contact with the limiting blocks 7 at the connected rotating rod 32. Among them, the inner side of the support rod 31, the inner side of the first adjusting rod 33 and the inner side of the second adjusting rod 34 are all in contact with the inner side of the rectangular structure. In this way, the four limiting blocks 7 can ensure that the support rod 31 is perpendicular to the two rotating rods 32, and the first adjusting rod 33 and the second adjusting rod 34 are perpendicular to the two rotating rods 32, thereby maintaining the shape of the rectangular structure and limiting the rotation angle of the first adjusting rod 33, the second adjusting rod 34 and the two rotating rods 32.

[0032] The limiting mechanism 36 is provided on the two rotating rods 32. The limiting mechanism 36 is used to limit the two rotating rods 32, the first adjusting rod 33 and the second adjusting rod 34 after the first adjusting rod 33 and the second adjusting rod 34 are unlocked and when the two rotating rods 32, the first adjusting rod 33 and the second adjusting rod 34 are rotated to be in the same straight line with the support rod 31, so that the two rotating rods 32, the first adjusting rod 33 and the second adjusting rod 34 can maintain a state of being in the same straight line with the support rod 31. In this way, the spraying mechanism 5 can spray one side of the object to be sprayed, and can spray multiple positions of the object to be sprayed on the same straight line at the same time, thereby expanding the spraying range and increasing the spraying speed.

[0033] The locking mechanism 35 may include: a locking rod 351, a lever 352 and a locking spring 353. The end surface of the second end of the first adjustment rod 33 is provided with a slot 331 extending toward the first end, and the end surface of the second end of the second adjustment rod 34 is provided with a sliding groove 341 extending toward the first end. The locking rod 351 is movably arranged in the sliding groove 341, and the first end of the locking rod 351 is placed in the sliding groove 341, and the first end of the locking rod 351 is connected to the inner wall of the sliding groove 341 through the locking spring 353, and the second end of the locking rod 351 is placed outside the sliding groove 341 and movably inserted into the slot 331. Specifically, the first end of the locking spring 353 is connected to the inner wall of the sliding groove 341, and the second end of the locking spring 353 is connected to the first end of the locking rod 351. When the first adjusting rod 33 and the second adjusting rod 34 are not locked, the second end of the locking rod 351 is placed outside the sliding groove 341. When the first adjusting rod 33 and the second adjusting rod 34 are locked, the second end of the locking rod 351 is movably inserted into the slot 331. The first adjusting rod 33 and the second adjusting rod 34 are locked by inserting the locking rod 351 into the slot 331.

[0034] A limiting groove 342 is formed on the side wall of the second adjusting rod 34 near the second end, and the limiting groove 342 is connected to the sliding groove 341. Specifically, the limiting groove 342 has a preset length, and the length direction of the limiting groove 342 is consistent with the length direction of the sliding groove 341. The lever 352 is movably disposed in the limiting groove 342, the first end of the lever 352 is disposed in the sliding groove 341 and connected to the locking rod 351, and the second end of the lever 352 is disposed outside the limiting groove 342 and is a free end.

[0035] When the first adjusting rod 33 and the second adjusting rod 34 need to be rotated, the staff manually moves the lever 352 to make the lever 352 move toward the first end of the second adjusting rod 34, and the lever 352 drives the locking rod 351 to move toward the inner wall of the sliding groove 341. The locking rod 351 compresses the locking spring 353, so that the second end of the locking rod 351 disengages from the slot 331. At this time, the first adjusting rod 33 and the second adjusting rod 34 are separated, and the first adjusting rod 33 and the second adjusting rod 34 can be rotated. At the same time, the staff can release the lever 352. When it is necessary to lock the first adjusting rod 33 and the second adjusting rod 34, the staff member pushes the lever 352 so that the lever 352 drives the locking rod 351 to move toward the inner wall of the sliding groove 341, and the locking rod 351 compresses the locking spring 353, aligning the second end of the first adjusting rod 33 with the second end of the second adjusting rod 34, and aligning the slot 331 with the locking rod 351. The staff member releases the lever 352, and under the action of the elastic restoring force of the locking spring 353, the locking spring 353 pushes the locking rod 351 to move into the slot 331 until the locking rod 351 is inserted into the slot 331. At this time, the locking spring 353 is in a free state, and the locking rod 351 locks the first adjusting rod 33 and the second adjusting rod 34, so that the first adjusting rod 33 and the second adjusting rod 34 are connected together.

[0036] In a specific implementation, there can be two limit grooves 342, which are respectively provided on two opposite side walls of the second adjustment rod 34 near the second end, and the two limit grooves 342 are both connected to the sliding groove 341. There are two levers 352, which correspond to the two limit grooves 342 one by one, and each lever 352 is movably disposed in the corresponding limit groove 342, and the first end of each lever 352 is connected to the locking rod 351, and the second end of each lever 352 is placed outside the limit groove 342.

[0037] The limiting mechanism 36 includes: two limiting plates 361 and four limiting components. The two limiting plates 361 correspond to the two rotating rods 32 one by one, and each limiting plate 361 is arranged on the outer side of the corresponding rotating rod 32, and the outer side of the rotating rod 32 is the outer side of the rectangular structure. The length of each limiting plate 361 is greater than the length of the rotating rod 32, the center of each limiting plate 361 corresponds to the center of the rotating rod 32, and both ends of each limiting plate 361 extend to the outside of the corresponding end of the rotating rod 32. A limiting component is arranged at each end of each limiting plate 361, and two limiting components are arranged on each limiting plate 361. These four limiting components work together to keep the two rotating rods 32, the first adjustment rod 33 and the second adjustment rod 34 in the same straight line with the support rod 31.

[0038] The top surface of the support rod 31, the top surfaces of the two rotating rods 32, the top surface of the first adjusting rod 33 and the top surface of the second adjusting rod 34 are provided with a spray mechanism 5. The bottom surfaces of the two ends of the support rod 31, the bottom surface of the first end of the first adjusting rod 33 and the bottom surface of the first end of the second adjusting rod 34 are all provided with positioning grooves 6.

[0039] Each limiting assembly includes: a connecting plate 362, a limiting column 363, a pulling plate 364 and a limiting spring 365. The connecting plate 362 is vertically arranged at the end of the limiting plate 361, and the connecting plate 362 and the rotating rod 32 are located on the same side, the connecting plate 362 and the length direction of the rotating rod 32 are parallel, and the position of the connecting plate 362 is located below the position of the rotating rod 32, but there is a certain distance between the position of the connecting plate 362 and the end of the rotating rod 32, that is, the connecting plate 362 is not placed directly below the end of the rotating rod 32. The connecting plate 362 is provided with a through hole, and the limiting column 363 can be slidably penetrated in the through hole. The first end of the limiting column 363 is connected to the pulling plate 364, and the cross-sectional size of the pulling plate 364 is larger than the cross-sectional size of the limiting column 363 and larger than the diameter of the through hole. In addition, the pulling plate 364 is placed below the connecting plate 362. The limiting spring 365 is sleeved on the outside of the limiting column 363, and the limiting spring 365 is arranged between the pull plate 364 and the connecting plate 362. Specifically, the limiting spring 365 is fixedly connected to the pull plate 364 and the connecting plate 362. The second end of the limiting column 363 is movably inserted into the corresponding positioning groove 6.

[0040] After the first adjusting rod 33 and the second adjusting rod 34 are unlocked, the staff manually pulls the pull plate 364 to move the limit column 363 downward, driving the limit spring 365 in a stretched state. Then, the first adjusting rod 33 is rotated so that the first adjusting rod 33 and the rotating rod 32 connected thereto are in the same straight line. The staff releases the pull plate 364. Under the elastic restoring force of the limit spring 365, the limit spring 365 drives the limit column 363 to be inserted into the positioning groove 6 on the bottom surface of the first adjusting rod 33. According to the above method, another limit column 363 is inserted into the positioning groove 6 on the bottom surface of the second adjusting rod 34. Then, the two rotating rods 32 are rotated again so that the two rotating rods 32 and the support rod 31 are in the same straight line. According to the above method, the other two limit columns 363 are inserted into the two positioning grooves 6 on the bottom surface of the support rod 31. At this time, the two rotating rods 32, the first adjusting rod 33, the second adjusting rod 34 and the support rod 31 are all in the same straight line.

[0041] In specific implementation, the positions of the positioning slots 6, the connecting plates 362 and the limiting posts 363 can be pre-designed according to actual conditions to ensure that when the first adjusting rod 33, the second adjusting rod 34 and the two rotating rods 32 are rotated until the supporting rods 31 are in the same straight line, the four limiting posts 363 can be accurately and one-to-one inserted into the four positioning slots 6. Each limiting post 363 is adapted to the corresponding positioning slot 6.

[0042] It can be seen that in the present embodiment, when the cross-section of the object to be sprayed is rectangular, the first adjusting rod 33, the second adjusting rod 34, the two rotating rods 32 and the support rod 31 are arranged in a rectangular structure, and the first adjusting rod 33 and the second adjusting rod 34 are inserted into the slot 331 for locking through the locking rod 351. In this way, the first adjusting rod 33, the second adjusting rod 34, the two rotating rods 32 and the support rod 31 are arranged in a circle along the object to be sprayed, completely surrounding the object to be sprayed, and the spraying mechanism 5 can spray the object to be sprayed all around at the same time, ensuring that water is evenly sprayed on the circumference of the object to be sprayed, thereby realizing the spraying maintenance of the object to be sprayed, and then the position of the first adjusting rod 33, the second adjusting rod 34, the two rotating rods 32 and the support rod 31 on the support column 2 is adjusted by the position adjustment mechanism 4, so that the spraying of the object to be sprayed at different heights can be realized, and the operation is simple and convenient. When spraying one side of the object to be sprayed, the two rotating rods 32, the first adjusting rod 33 and the second adjusting rod 34 are rotated so that the first adjusting rod 33, the second adjusting rod 34 and the two rotating rods 32 are in the same straight line with the support rod 31. The limiting mechanism 36 limits the first adjusting rod 33, the second adjusting rod 34 and the two rotating rods 32 so that the first adjusting rod 33, the second adjusting rod 34 and the two rotating rods 32 are kept in the same straight line with the support rod 31. Then, the positions of the first adjusting rod 33, the second adjusting rod 34, the two rotating rods 32 and the support rod 31 on the support column 2 are adjusted by the position adjustment mechanism 4, so that spraying at different heights can be achieved.

Guide grooves 411 are provided on opposite sides of the mounting block 41, and the two guide grooves 411 correspond to the two guide columns 46 one by one, and each guide groove 411 is slidably connected to the corresponding guide column 46. In this way, when the mounting block 41 moves along the height direction of the support column 2, the two guide grooves 411 on the mounting block 41 slide along the corresponding guide columns 46, and the guide columns 46 limit the moving trajectory of the mounting block 41, ensure the stable movement of the mounting block 41, prevent the mounting block 41 from being offset during movement, and avoid the mounting block 41 from slipping.

[0050] It can be seen that in this embodiment, the position adjustment mechanism 4 has a simple structure and is easy to implement.

[0051] See also Figure 1 to Figure 2 In the above embodiment, the spray mechanism 5 includes: a flexible connecting pipe 51, a water pumping pipe 52 and a plurality of spray heads 53. Among them, each spray head 53 is arranged at intervals on the support device 3, and specifically, each spray head 53 is arranged on the support rod 31, the first adjustment rod 33, the second adjustment rod 34 and the two rotating rods 32. Each spray head 53 on the support rod 31, each spray head 53 on the first adjustment rod 33, each spray head 53 on the second adjustment rod 34 and each spray head 53 on the two rotating rods 32 are arranged at intervals, preferably evenly distributed.

[0052] The connecting pipe 51 is connected to each of the nozzles 53 , and the connecting pipe 51 is in communication with each of the nozzles 53 .

[0053] The first end of the water pumping pipe 52 is connected to the connecting pipe 51, and the second end of the water pumping pipe 52 is used to connect to the water pumping device. The water pumping device pumps water and transports it to the connecting pipe 51, and then transports it to each nozzle 53 through the connecting pipe 51, and each nozzle 53 sprays water.

[0054] It can be seen that in this embodiment, the structure of the spray mechanism 5 is simple and easy to implement, and the connecting pipe 51 is flexible. In this way, when the two rotating rods 32, the first adjusting rod 33 and the second adjusting rod 34 rotate, the flexibility of the connecting pipe 51 enables the connecting pipe 51 to change its shape, which is convenient for adjusting the shape of the supporting device 3.

[0055] Combination Figures 1 to 5The use process of the maintenance spray device is introduced, and the concrete column with a rectangular cross-section as the object to be sprayed is taken as an example: when in use, the two levers 352 are pulled, and the two levers 352 slide in their respective limit grooves 342, and the two levers 352 drive the locking rod 351 to move toward the inner wall of the sliding groove 341, and the locking rod 351 compresses the locking spring 353 and is pulled out from the slot 331. At this time, the restriction between the first adjusting rod 33 and the second adjusting rod 34 can be released, and the first adjusting rod 33 and the second adjusting rod 34 can be rotated so that the first adjusting rod 33 and the second adjusting rod 34 are both in the same straight line with the corresponding rotating rod 32. Then, push the base 1 to move the support column 2, so that the support column 2 and the support device 3 move together, the support rod 31 and the two rotating rods 32 surround the concrete column, and then reversely rotate the first adjustment rod 33 and the second adjustment rod 34, and use the locking rod 351 to lock the first adjustment rod 33 and the second adjustment rod 34 together. At this time, the first adjustment rod 33, the second adjustment rod 34, the two rotating rods 32 and the support rod 31 are surrounded into a rectangle, and the installation is completed. Connect the water pump 52 to the water pump, the water pump pumps water and transports it to the water pump 52, the water pump 52 transports the water to the connecting pipe 51, and then sprays it around the concrete column through each nozzle 53. During the spraying process, the drive motor 42 is turned on, and the driving end of the drive motor 42 drives the first transmission wheel 8 to rotate, and then drives the second transmission wheel 9 to rotate through the transmission belt 10. The rotation of the second transmission wheel 9 drives the support shaft 43 connected thereto to rotate, and then drives the chain 45 and another support shaft 43 to rotate. The rotation of the chain 45 drives the mounting block 41 to move up and down along the height direction of the support column 2. When moving, the mounting block 41 slides on the corresponding guide column 46 through the two guide grooves 411 to prevent the mounting block 41 from slipping. The mounting block 41 drives the support rod 31 to move, and then drives the two rotating rods 32, the first adjustment rod 33 and the second adjustment rod 34 to move together, and then drives the various nozzles 53 thereon to move together, so that the nozzles 53 can be moved and sprayed. By controlling the forward and reverse rotation of the drive motor 42, each nozzle 53 can be raised or lowered along the height direction of the support column 2.

[0056] When spraying is required on the wall, the first adjusting rod 33 and the second adjusting rod 34 are first unlocked, and then the two pull plates 364 near the first adjusting rod 33 and the second adjusting rod 34 are pulled downward. When each pull plate 364 moves, it drives the corresponding limit column 363 to move away from the connecting plate 362. The continuously moving pull plate 364 stretches the limit spring 365, and then the first adjusting rod 33 and the second adjusting rod 34 are rotated, so that the first adjusting rod 33 and the second adjusting rod 34 are respectively in contact with the two limit plates 36 on the corresponding sides. 1, and the first adjusting rod 33 and the second adjusting rod 34 are respectively in the same straight line with the corresponding rotating rod 32. At the same time, the positioning grooves 6 on the first adjusting rod 33 and the second adjusting rod 34 correspond to the two limiting columns 363 respectively. At this time, the corresponding pull plate 364 is released, and the limiting spring 365 in the stretched state will retract and drive the pull plate 364 to move and reset. The reset pull plate 364 will drive the limiting column 363 to insert into the corresponding positioning groove 6 to limit the angle of the first adjusting rod 33 and the second adjusting rod 34. Then, pull the two pull plates 364 near the support rod and rotate the two rotating rods 32 so that the limit plates 361 on the two rotating rods 32 contact the support rod 31. At this time, the two rotating rods 32 and the support rod 31 are in the same straight line. Similarly, loosen the pull plate 364 so that the limit column 363 is inserted into the corresponding positioning groove 6. At this time, the support rod 31, the two rotating rods 32, the first adjustment rod 33 and the second adjustment rod 34 are all in the same straight line. At this time, each nozzle 53 is also in the same straight line. Move the base 1 to the front of the wall, and each nozzle 53 is also located in the front of the wall and sprays water to the wall. Start the drive motor 42, and drive the mounting block 41 and the support device 3 to move up and down along the height direction of the support column 2 through the transmission mechanism, so that each position in the height direction of the wall can be sprayed.

[0057] In summary, in the present embodiment, the spray mechanism 5 is arranged on the supporting device 3, and the position adjusting mechanism 4 adjusts the position of the supporting device 3 on the supporting column 2, that is, adjusts the position of the spray mechanism 5, so that it can spray positions at different heights on the sprayed object without the need to adjust the position by holding the water pipe, and the operation is simple. In addition, the shape of the supporting device 3 itself is adjustable, and the shape can be changed according to the needs of the sprayed object, so as to better spray the sprayed object, simplify the spraying process, and improve the construction efficiency.
