Description

Technical Field

[0001] This application relates to the field of building construction, and in particular, to a water spraying and roughening device. Background Art

[0002] The roughening device is applicable to roughening operations on smooth concrete surfaces such as building walls, bottom plates of finished components, and stair surfaces of finished components, so as to increase the roughness of the wall surface, thereby improving the adhesion of subsequent cement or other gummy substances to the wall surface. After tiles are laid on the wall surface, the tiles are not prone to local hollowing, falling off and other phenomena.

[0003] Currently, there are two common roughening treatment methods. One is to use a cutting machine to draw many grooves on the wall; the other is water spraying and roughening. The water spraying and roughening device includes a water spraying pipe, a high-pressure nozzle, a handle, and a pressurizing device. When construction workers perform roughening treatment through the water spraying and roughening device, first, they hold the handle by hand and make the handle drive the high-pressure nozzle to be at a certain distance from the wall to be constructed. Then, the pressurizing device is started. After the water in the water tank is pressurized by the pressurizing device, it is sprayed out by the high-pressure nozzle, and then the roughening operation can be carried out on the wall surface. However, construction workers need to reciprocate the handle and the high-pressure nozzle up and down for a long time to roughen the wall surface, with a high labor intensity. Moreover, during the process of the human hand driving the high-pressure nozzle to move up and down, it is difficult to control the distance between the high-pressure nozzle and the wall surface, and it is difficult to accurately and uniformly control the spraying distance and the roughening speed. As a result, after the wall surface is roughened, the roughening effect of the wall body is uneven. Summary of the Invention

[0004] In order to improve the uniformity of the wall surface roughening by the water spraying and roughening device, improve the roughening quality, and reduce the labor intensity required for construction workers to roughen a large area, this application provides a water spraying and roughening device.

[0005] A water spraying and roughening device provided by this application adopts the following technical solutions:

[0006] A water spraying and roughening device includes a device body, a high-pressure resistant water pipe arranged on the device body, a handle communicated with the high-pressure resistant water pipe, a high-pressure nozzle arranged on one side of the handle, a moving trolley arranged on one side of the device body, a column arranged above the moving trolley, a support plate arranged on one side of the column, a lifting, translation and telescopic mechanism arranged between the column and the support plate for driving the support plate to move in the horizontal and height directions and simultaneously accurately controlling the distance between the high-pressure nozzle and the wall surface, and a fixing mechanism arranged between the support plate and the handle for fixing the handle.

[0007] By adopting the above technical solution, when the wall surface is roughened by the water spraying and roughening equipment, first, the construction worker fixes and supports the handle and the support plate through the fixing mechanism. Then, the high-pressure nozzle is moved to the construction position to be processed by the moving trolley. Subsequently, the construction worker starts the lifting, translating and telescoping mechanism. The lifting, translating and telescoping mechanism drives the high-pressure nozzle to perform roughening operations in the height direction. After the roughening operation in the height direction is completed, it horizontally moves a certain distance. Then, the lifting, translating and telescoping mechanism continues to drive the high-pressure nozzle to perform roughening operations in the height direction, and the above process is repeated in turn, so that the high-pressure nozzle completes the roughening operation in a certain area of the construction position to be processed. After the roughening operation in this wall area is completed, the construction worker moves the moving trolley to the next construction site, and repeats the above process to roughen the wall of the next location; wherein the lifting, translating and telescoping mechanism can drive the high-pressure nozzle to automatically perform roughening operations in the horizontal and vertical directions within a certain area of the wall. And during the up and down movement of the high-pressure nozzle, the distance between the high-pressure nozzle and the wall surface is always constant, which not only reduces the labor intensity required for large-area roughening by construction workers, but also can accurately and evenly control the spraying distance and roughening speed, improving the uniformity and quality of the wall roughening by the water spraying and roughening device.

[0008] Optionally, the lifting, translating and telescoping mechanism includes a telescopic rod arranged horizontally and slidably connected to the column, a sliding frame slidably connected to one side of the telescopic rod, a translation component arranged between the telescopic rod and the sliding frame for driving the sliding frame to slide along the length direction of the telescopic rod, a lifting component arranged between the telescopic rod and the column for driving the telescopic rod to move up and down, and a guiding and reinforcing component arranged between the telescopic rod and the column for guiding and reinforcing the movement of the telescopic rod when it moves up and down; the telescopic rod slides along the height direction of the column, and the sliding frame is fixedly connected to the support plate.

[0009] By adopting the above technical solution, when the high-pressure nozzle is driven to perform automatic hairspraying operations by the lifting, translating and telescoping mechanism, first, the construction worker drives the telescopic rod to move up and down through the lifting component. Then, the telescopic rod can drive the sliding frame, the handle, the support plate and the high-pressure nozzle to move up and down, so that the high-pressure nozzle can perform roughening operations on the wall surface. When a roughening operation in the height direction of the wall is completed, the construction worker can drive the high-pressure nozzle to automatically move a certain distance to the left or right through the translation component. Subsequently, the lifting component is started again to drive the high-pressure nozzle to perform roughening operations on the wall surface in the height direction. By repeating this process, roughening operations can be carried out within a certain area of the wall surface; wherein the telescopic rod can be telescoped along its length direction, so that when the construction worker moves the water spraying and roughening equipment to the construction site to be processed, the longer telescopic rod can be retracted into a smaller volume, which is convenient for the water spraying and roughening equipment to pass through the door opening and enter the room for roughening operations, improving the convenience of the construction worker to carry, transport and handle the roughening equipment.

[0010] Optionally, the translation component includes a sliding block fixedly arranged on one side of the sliding frame close to the telescopic rod, a driving motor arranged on one side of the sliding frame, a driving gear fixedly sleeved on one end of the output shaft of the driving motor, and a driving rack fixedly arranged inside the telescopic rod;

[0011] A sliding groove is formed on one side of the telescopic rod, the sliding block is located in the sliding groove and slides therein, the output shaft of the driving motor penetrates through the sliding block and is rotatably connected to the sliding block, and the driving gear meshes with the driving rack.

[0012] By adopting the above technical solution, when the translation component drives the high-pressure nozzle to move horizontally, first, the construction worker starts the driving motor, and then the output shaft of the driving motor drives the driving gear to rotate. Under the guiding action of the driving rack and the sliding block, the driving gear can move along the length direction of the driving rack. Subsequently, the driving gear can drive the driving motor, the sliding block, the sliding frame, and the high-pressure nozzle to move horizontally along the length direction of the telescopic rod, thereby adjusting the horizontal spraying position of the high-pressure nozzle.

[0013] Optionally, limiting blocks are also fixedly arranged on the upper and lower sides of the sliding block, a limiting groove is formed along the length direction of the telescopic rod, and the limiting blocks are located in the limiting groove and slide therein.

[0014] By adopting the above technical solution, the limiting blocks not only limit the movement of the sliding block, but also make it difficult for the sliding block and the sliding frame to separate from the telescopic rod. Moreover, the driving gear is kept at a certain distance from the telescopic rod, so that the driving gear is not easily scratched by the telescopic rod during the movement, thereby making the movement of the driving gear smoother.

[0015] Optionally, the telescopic rod includes a plurality of support rods hinged to each other, and a locking component arranged between two adjacent support rods for locking the two adjacent support rods when they are rotated to the same straight line.

[0016] By adopting the above technical solution, after the construction worker moves the water spraying and roughening equipment to the position to be constructed, first, the plurality of support rods can be rotated around their respective rotation axes to the same straight line, and then the adjacent two support rods are fixed by the locking component, so that the splicing of the telescopic rod can be realized. The spliced telescopic rod is relatively long. After the construction worker moves the trolley once and keeps the two ends of the telescopic rod at the same distance from the wall, the water spraying and roughening equipment can perform the water spraying and roughening operation on a region of the wall surface. This not only facilitates the transportation of the roughening equipment, but also reduces the time required to adjust the distance between the two ends of the telescopic rod and the wall surface after moving the trolley multiple times, improving the roughening efficiency and effect.

[0017] Optionally, the locking assembly includes a telescopic guide rod with one end fixedly arranged on one side of the support rod, a thrust spring sleeved outside the guide telescopic rod, and a clamping block fixedly arranged at the other end of the telescopic guide rod; a receiving groove is formed on one side of the support rod, the guide rod, the thrust spring and the clamping block are all located in the receiving groove, one end of the clamping block extends out of the receiving groove and is located outside the support rod, and one side of the clamping block extending out of the receiving groove is inclined, and the thrust spring is always in a compressed state;

[0018] A clamping groove is formed on the side of the support rod away from the clamping block, the clamping block can be inserted into the clamping groove of the adjacent support rod, and a push rod is also slidably connected in the clamping groove, and one end of the push rod abuts against the inclined surface of the clamping block.

[0019] By adopting the above technical solution, when multiple support rods rotate to the same straight line around their respective rotation axes, the clamping block at one end of the support rod will drive the telescopic guide rod to expand and contract under the action of the clamping groove and the inclined surface of the clamping block itself, and at the same time the thrust spring is further compressed. Until the clamping block completely enters the clamping groove, the thrust spring will drive the clamping block to move to the side away from the telescopic guide rod, so that the end of the clamping block with an inclined surface is clamped in the clamping groove, thereby realizing the locking of two adjacent support rods; when the construction personnel need to release the locking state of two adjacent support rods, only need to press the push rod, the push rod can drive the telescopic guide rod to contract, and then rotate one of the support rods, the two adjacent support rods can be separated; the splicing and locking and unlocking operations of the telescopic rod are simple and convenient.

[0020] Optionally, the lifting and translation telescopic mechanism further includes

[0021] Two detection modules, connected to both ends of the telescopic rod, for detecting the distance between the end of the telescopic rod and the wall surface, and sending out a distance value detection signal;

[0023] A controller, connected to the detection module, for receiving the distance value detection signal, and if the difference between the two distance value detection signals exceeds the allowable error, the warning lamp will light up;

[0024] A display, connected to the controller.

[0025] By adopting the above technical solution, the detection module will detect the distance between both ends of the telescopic rod and the wall surface, and send out a distance value detection signal, and the display will simultaneously display the distance value between the telescopic rod and the wall surface, so as to facilitate the construction personnel to adjust the distance between the high-pressure nozzle and the wall surface, so as to achieve the best roughening effect. At the same time, when the distance difference between both sides of the telescopic rod exceeds the allowable error, the warning lamp will light up to remind the construction personnel to adjust the moving trolley, so that the distance between both ends of the telescopic rod and the wall surface is kept consistent, and the telescopic rod is not prone to deflection.

[0026] Optionally, the lifting assembly includes a lifting block fixedly arranged on one side of the telescopic rod close to the column, a reciprocating lead screw rotatably connected in the column along the height direction of the column, a gear set arranged at one end of the reciprocating lead screw, and a power motor arranged between the gear set and the column;

[0027] A lifting groove is formed in the column along its height direction, the lifting block is located in the lifting groove and slides therein, and the reciprocating lead screw is in threaded connection with the lifting block.

[0028] By adopting the above technical solution, when the high-pressure nozzle is driven to move up and down reciprocally by the lifting assembly, first, the construction worker starts the power motor, then the power motor drives the reciprocating lead screw to rotate, the reciprocating lead screw drives the lifting block to move up and down, and the lifting block can drive the telescopic rod and the high-pressure nozzle to move up and down; wherein the reciprocating lead screw only needs to rotate the output shaft of the power motor in one direction, so that the power motor is not easily damaged, and the service life and stability of the water spraying and roughening equipment are improved.

[0029] Optionally, the guiding and reinforcing assembly includes four stay blocks respectively fixedly arranged on the telescopic rod and rollers rotatably connected to the side of the stay block close to the column. A guiding groove is formed in the column along its height direction, and the rollers are located in the guiding groove and roll therein.

[0031] Optionally, the fixing mechanism includes a snap ring rotatably connected to one side of the support plate and a plurality of connecting bolts threadedly connected between the snap ring and the support plate. The connecting bolts are located on the side of the snap ring away from its hinge axis, and the handle abuts between the inner side walls of the support plate and the snap ring.

[0032] By adopting the above technical solution, the construction worker can fix and release the handle by tightening or loosening the connecting bolts. The method of fixing the high-pressure nozzle is simple and convenient, and the original characteristics of the handle are not affected, with good stability and convenient disassembly.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The lifting, translation and telescoping mechanism can drive the high-pressure nozzle to automatically perform roughening operations along the horizontal and vertical directions within a certain area of the wall. And during the up and down movement of the high-pressure nozzle, the distance between the high-pressure nozzle and the wall surface is always constant. Thus, it not only reduces the labor intensity required for large-area roughening by construction workers, but also can accurately and uniformly control the spraying distance and roughening speed, improving the uniformity and roughening quality of the wall surface roughening by the water spraying and roughening device;

[0035] 2. In the lifting, translating and telescoping mechanism, the telescopic rod can be telescoped along its length direction. When the construction worker moves the water spraying and roughening device to the construction site to be operated, the longer telescopic rod can be retracted into a smaller volume, so as to facilitate the water spraying and roughening device to pass through the door opening and enter the room for roughening operation, improving the convenience for the construction worker to carry, transport and move the roughening device.

[0036] 3. The limit block not only limits the movement of the sliding block, but also makes it difficult for the sliding block and the sliding frame to separate from the telescopic rod. Moreover, it keeps a certain distance between the driving gear and the telescopic rod, so that the driving gear is not easily scratched by the telescopic rod during movement, thus making the movement of the driving gear smoother.

[0037] 4. After the spliced telescopic rod is relatively long, when the construction worker moves the moving trolley once and keeps the two ends of the telescopic rod at the same distance from the wall, the water spraying and roughening device can carry out the water spraying and roughening operation on a certain area of the wall. This not only facilitates the handling and transportation of the roughening device, but also reduces the time required to adjust the distance between the two ends of the telescopic rod and the wall after moving the trolley multiple times, improving the roughening efficiency and effect.

[0038] 5. When the construction worker needs to release the locking state of two adjacent support rods, only need to press the push rod, and the push rod can drive the telescopic guide rod to contract. Then rotate one of the support rods, and the two adjacent support rods can be separated; the splicing locking and unlocking operations of the telescopic rod are simple and convenient.

[0039] 6. The detection module will detect the distance between the two ends of the telescopic rod and the wall and send out a distance value detection signal. The display will simultaneously display the distance value between the telescopic rod and the wall, so as to facilitate the construction worker to adjust the distance between the high-pressure nozzle and the wall to achieve the best roughening effect. At the same time, when the distance difference between the two sides of the telescopic rod exceeds the allowable error, the warning light will light up to remind the construction worker to adjust the moving trolley, so that the distances between the two ends of the telescopic rod and the wall are kept consistent and the telescopic rod is not easily deflected.

[0040] 7. When the telescopic rod moves up and down, it will drive the four diagonal pulling blocks and rollers to move accordingly. The diagonal pulling blocks and rollers are used to keep the telescopic rod horizontal and reduce the stress concentration at the connection between the telescopic rod and the column, strengthening the support for the telescopic rod.

Detailed implementation manners

[0049] The following will further elaborate on this application in conjunction with the attached Figures 1-7 drawings.

[0050] The embodiment of this application discloses a water spraying and roughening device. Referring to Figure 1 and Figure 2 , the water spraying and roughening device includes an equipment body 1. A high-pressure resistant water pipe 2 is arranged on the equipment body 1. One end of the high-pressure resistant water pipe 2 far from the equipment body 1 is communicated with a handle 3, and a high-pressure nozzle 4 is connected to one end of the handle 3. A mobile trolley 5 is further arranged on one side of the equipment body 1, and a column 6 is fixedly arranged vertically above the mobile trolley 5; a support plate 7 is arranged at intervals on one side of the column 6, and a lifting and translation telescopic mechanism 8 is arranged between the column 6 and the support plate 7. The lifting and translation telescopic mechanism 8 is used to drive the support plate 7 to move in the horizontal and height directions, and at the same time, the distance between the high-pressure nozzle 4 and the wall surface can be accurately controlled. A fixing mechanism 9 is also arranged between the support plate 7 and the handle 3, and the fixing mechanism 9 is used to fix the handle 3.

[0051] Referring to Figure 2, the fixing mechanism 9 includes a clamping ring 91 rotatably connected to one side of the support plate 7. A plurality of connecting bolts 92 are threadedly connected between the clamping ring 91 and the support plate 7. The connecting bolts 92 are located on the side of the clamping ring 91 away from its hinge axis, and the handle 3 abuts between the inner side walls of the support plate 7 and the clamping ring 91.

[0052] When the wall surface is roughened by the water spraying and roughening device, first, the construction worker places the handle 3 between the inner side walls of the support plate 7 and the clamping ring 91, and then tightens the connecting bolts 92 to realize the fixed support of the handle 3 and the support plate 7. Then, the construction worker moves the high-pressure nozzle 4 to the construction position to be constructed through the moving trolley 5. Subsequently, the construction worker starts the lifting, translating and telescoping mechanism 8. The lifting, translating and telescoping mechanism 8 drives the high-pressure nozzle 4 to perform roughening operations in the height direction, and horizontally moves a certain distance after the roughening operation in the height direction is completed. Then, the lifting, translating and telescoping mechanism 8 continues to drive the high-pressure nozzle 4 to perform roughening operations in the height direction, and repeats the above process in turn, so that the high-pressure nozzle 4 completes the roughening operations in the horizontal and vertical directions within a certain area of the construction position to be constructed. Moreover, during the up-and-down movement of the high-pressure nozzle 4, the distance between the high-pressure nozzle 4 and the wall surface is always constant, thereby improving the uniformity and quality of the roughening of the wall surface by the water spraying and roughening device. After the roughening operation in this wall area is completed, the construction worker moves the moving trolley 5 to the next construction site and repeats the above process to roughen the wall of the next construction site.

[0053] Refer to Figure 3 and Figure 4 , the lifting, translating and telescoping mechanism 8 includes a telescopic rod 81 arranged in the horizontal direction. The telescopic rod 81 is slidably connected to the column 6 along the height direction of the column 6. A sliding frame 82 is arranged on the side of the telescopic rod 81 away from the column 6. The sliding frame 82 is fixedly connected to the support plate 7. A translation component 83 is arranged between the telescopic rod 81 and the sliding frame 82. The translation component 83 is used to drive the sliding frame 82 to slide along the length direction of the telescopic rod 81. A lifting component 84 is arranged between the telescopic rod 81 and the column 6. The lifting component 84 is used to drive the telescopic rod 81 to move up and down. A guiding and reinforcing component 85 is arranged between the telescopic rod 81 and the column 6. The guiding and reinforcing component 85 is used to guide and reinforce the movement of the telescopic rod 81 when the telescopic rod 81 moves up and down.

[0054] Refer to Figure 3 and Figure 4, the lifting, translating and telescoping mechanism 8 further includes two detection modules 86, a warning lamp 87 connected to one side of the column 6, a controller, and a display 88 connected to the column 6. The detection module 86 is an infrared sensor. The two infrared sensors are respectively connected to both ends of the telescopic rod 81, and are used to detect the distance between the end of the telescopic rod 81 and the wall surface, and issue a distance value detection signal. The controller is connected to the infrared sensor and the display 88, and is used to receive the distance value detection signal. If the difference between the two distance value detection signals exceeds the allowable error, the warning lamp 87 will light up. At the same time, the display 88 can also display the distance between the infrared sensor probe and the wall surface. The infrared sensor will detect the distances between both ends of the telescopic rod 81 and the wall surface and issue a distance value detection signal. The display 88 will simultaneously display the distance value of the telescopic rod 81 from the wall surface, so as to facilitate the construction personnel to adjust the distance between the high-pressure nozzle 4 and the wall surface, so as to achieve the best roughing effect. At the same time, when the distance difference between both sides of the telescopic rod 81 exceeds the allowable error, the warning lamp 87 will light up to remind the construction personnel to adjust the moving trolley 5, so that the distances between both ends of the telescopic rod 81 and the wall surface are kept consistent, and the telescopic rod 81 is not prone to deflection.

[0055] Referring to Figure 4 and Figure 5 , the translation assembly 83 includes a sliding block 831 fixedly arranged on the side of the sliding frame 82 close to the telescopic rod 81. A sliding groove is formed on one side of the telescopic rod 81, and the sliding block 831 is located in the sliding groove and slides. Limiting blocks 832 are also fixedly arranged on the upper and lower sides of the sliding block 831. A limiting groove is formed along the length direction of the telescopic rod 81, and the limiting blocks 832 are located in the limiting groove and slide. The limiting blocks 832 are not only used to limit the movement of the sliding block 831, but also make it difficult for the sliding block 831 and the sliding frame 82 to separate from the telescopic rod 81. A driving motor 833 is arranged on one side of the sliding frame 82. The output shaft of the driving motor 833 penetrates through the sliding block 831 and is rotatably connected to the sliding block 831. A driving gear 834 is fixedly sleeved at one end of the output shaft of the driving motor 833. A driving rack 835 is fixedly arranged inside the telescopic rod 81. The driving gear 834 meshes with the driving rack 835, and the limiting block 832 is also used to keep a certain distance between the driving gear 834 and the telescopic rod 81, so that the driving gear 834 is not prone to rubbing against the telescopic rod 81 during movement, and the movement of the driving gear 834 is smoother.

[0056] Referring to Figure 6 , the lifting assembly 84 includes a lifting block 841 fixedly arranged on the side of the telescopic rod 81 close to the column 6. A lifting groove 61 is formed along the height direction of the column 6, and the lifting block 841 is located in the lifting groove 61 and slides. A reciprocating lead screw 842 is rotatably connected inside the column 6. The reciprocating lead screw 842 is arranged along the height direction of the column 6, and the reciprocating lead screw 842 is threadedly connected to the lifting block 841. A gear set 843 is arranged at one end of the reciprocating lead screw 842. A power motor 844 is arranged between the gear set 843 and the column 6.

[0057] Referring to Figure 6 , the guiding and reinforcing assembly 85 includes four stay blocks 851 respectively fixed on the telescopic rod 81. A roller 852 is rotatably connected to one side of the stay block 851 close to the column 6. A guiding groove 62 is formed in the column 6 along its height direction, and the roller 852 rolls in the guiding groove 62. When the telescopic rod 81 moves up and down, it will drive the four stay blocks 851 and the rollers 852 to move accordingly. The stay blocks 851 and the rollers 852 are used to keep the telescopic rod 81 horizontal, reduce the stress concentration at the connection between the telescopic rod 81 and the column 6, and strengthen the support for the telescopic rod 81.

[0058] Referring to Figure 6 and Figure 7 , the telescopic rod 81 includes a plurality of support rods 811 hinged to each other. A locking assembly 812 is arranged between two adjacent support rods 811. The locking assembly 812 is used to lock the two adjacent support rods 811 when they are rotated to the same straight line. The locking assembly 812 includes a telescopic guide rod 8121 fixed to one side of the support rod 811 at one end. A thrust spring 8122 is sleeved outside the telescopic guide rod 8121, and the thrust spring 8122 is always in a compressed state. A block 8123 is fixed to the other end of the telescopic guide rod 8121. A receiving groove 8111 is formed in one side of the support rod 811. The guide rod, the thrust spring 8122 and the block 8123 are all located in the receiving groove 8111. One end of the block 8123 extends out of the receiving groove 8111 and is located outside the support rod 811. A clamping groove 8112 is formed in the side of the support rod 811 away from the block 8123, and the block 8123 can be inserted into the clamping groove 8112 of the adjacent support rod 811. One side of the block 8123 extending out of the receiving groove 8111 is inclined. A push rod 8124 is also slidably connected in the clamping groove 8112, and one end of the push rod 8124 abuts against the inclined surface of the block 8123. A return spring 8125 is sleeved outside the push rod 8124. One end of the return spring 8125 is fixedly connected to the support rod 811 and the other end is fixedly connected to the push rod 8124.

[0059] When construction workers move the water spraying and roughening equipment to the position to be constructed for automatic roughening operation, first, multiple support rods 811 can be rotated around their respective rotation axes to the same straight line. Then, under the action of the slot 8112 and the inclined plane of the clamping block 8123 itself at one end of the support rod 811, the telescopic guide rod 8121 is driven to expand and contract, and at the same time, the thrust spring 8122 is further compressed. Until the clamping block 8123 completely enters the slot 8112, the thrust spring 8122 will drive the clamping block 8123 to move to the side away from the telescopic guide rod 8121, so that the end of the clamping block 8123 with an inclined plane is clamped into the slot 8112, thus realizing the locking of two adjacent support rods 811 and the splicing of the telescopic rod 81. Then, the staff observes through the display screen 88 and adjusts the distances between the two ends of the telescopic rod 81 and the wall surface. The telescopic rod 81 can be telescoped along its length direction, so that when construction workers move the water spraying and roughening equipment to the construction site to be constructed, the longer telescopic rod 81 can be stored in a smaller volume, which is convenient for the water spraying and roughening equipment to pass through the door opening and enter the room for roughening operation, improving the convenience of construction workers to carry, transport and handle the roughening equipment.

[0060] Subsequently, the construction worker starts the power motor 844. Then, the power motor 844 drives the reciprocating lead screw 842 to rotate, and the reciprocating lead screw 842 drives the lifting block 841 to move up and down. The lifting block 841 drives the telescopic rod 81 to move up and down. Then, the telescopic rod 81 can drive the sliding frame 82, the handle 3, the support plate 7 and the high-pressure nozzle 4 to move up and down, so that the high-pressure nozzle 4 can roughen the wall surface. When a roughening operation on the wall surface in the height direction is completed, the construction worker starts the driving motor 833. The output shaft of the driving motor 833 drives the driving gear 834 to rotate. Under the guiding action of the driving rack 835 and the sliding block 831, the driving gear 834 can move along the length direction of the driving rack 835. Then, the driving gear 834 can drive the driving motor 833, the sliding block 831, the sliding frame 82 and the high-pressure nozzle 4 to move horizontally along the length direction of the telescopic rod 81, so as to adjust the horizontal spraying position of the high-pressure nozzle 4, so that the high-pressure nozzle 4 automatically moves a certain distance to the left or right. Then, start the power motor 844 again to drive the high-pressure nozzle 4 to roughen the wall surface in the height direction. By repeating this process, the roughening operation on a certain area of the wall surface can be realized.

[0061] The implementation principle of a water spraying and texturing device in an embodiment of this application is as follows: When the water spraying and texturing device is used to texture a wall surface, first, the construction worker fixes and supports the handle 3 to the support plate 7 through the snap ring 91 and the connecting bolt 92. Then, the high-pressure nozzle 4 is moved to the construction position to be processed by the mobile trolley 5. Subsequently, the construction worker adjusts the telescopic rod 81 to be parallel to the wall surface through the mobile trolley 5 in cooperation with the infrared sensor and the display 88. Then, the power motor 844 is started, and the power motor 844 controls and drives the high-pressure nozzle 4 to perform texturing operations in the height direction. After the texturing operation in the height direction is completed, it moves horizontally a certain distance. Then, the lifting, translation, and telescopic mechanism 8 continues to drive the high-pressure nozzle 4 to perform texturing operations in the height direction. The above process is repeated in sequence, so that the high-pressure nozzle 4 completes the texturing operation within a certain area of the construction position to be processed. After the texturing operation in this wall area is completed, the construction worker moves the mobile trolley 5 to the next construction site, and repeating the above process can texture the wall of the next construction site; wherein the lifting, translation, and telescopic mechanism 8 can drive the high-pressure nozzle 4 to perform automatic texturing operations on a certain area of the wall in its horizontal and vertical directions. Moreover, when the high-pressure nozzle 4 moves up and down, the distance between the high-pressure nozzle 4 and the wall surface is always constant. This not only reduces the labor intensity required for the construction worker to perform large-area texturing, but also can accurately and evenly control the spraying distance and the texturing speed, improving the uniformity and texturing quality of the water spraying and texturing device for the wall surface.

[0062] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
