[0002] During construction, waterproofing materials are applied to certain areas according to design requirements. These materials come in various types, each suited to different applications, primarily serving as insulation and waterproofing. During application, pressure is used to coat or fill the waterproofing material into the designed location until a protective layer of the designed thickness is formed. The overall thickness and uniformity of the waterproofing material during application determine the overall construction quality. Furthermore, to conserve resources, it is necessary to ensure construction quality while maximizing the utilization rate of the waterproofing material.

[0018] like Figure 1-6An automated waterproof material mixing and spraying device includes a trolley 2 supported on an upper lifting beam 1. The trolley 2 is equipped with a spraying component 3 and a mixing component 4. The spraying component 3 is connected to the trolley 2 via a lifting component 8. The spraying component 3 includes a connecting seat 301 and a square tube 302. The connecting seat 301 is inserted into the top of the lifting component 8. A rack 303 is slidably provided inside the square tube 302. A nozzle 305 is provided at the end of the rack 303. The spraying area of ​​the nozzle 305 can be changed by adjusting the position of the rack 303. The mixing component 4 includes a cylinder 401. A stirring rod 12 and a scraping component 13 are respectively provided in the middle and on the inner side of the cylinder 401. The nozzle 305 is connected to the mixing component 4 via a pipe 5.

[0019] During construction, the partition 103 of the upturned beam 1 divides and breaks up the construction area, requiring tools to be repeatedly moved back and forth between multiple areas. When spraying waterproof material onto the upturned beam 1, the overall workload is large, the labor intensity is high, the overall construction efficiency is low, and the construction quality is difficult to guarantee. To solve the above problems, this application cleverly uses the upper part of the upturned beam 1 as a channel to run through the entire area, so that the trolley 1 can travel on it. This facilitates the mixing of waterproof material by the mixing component 4 to form a foaming mixture. The waterproof material is then extracted from the mixing component 4 by the air compressor and pipeline 5 and sprayed onto the relevant areas by the spraying component 3, ensuring the quality and efficiency of the construction.

[0020] In a preferred embodiment, the upward-turning beam 1 includes a vertically arranged crossbeam 101 and a longitudinal beam 102. Adjacent crossbeams 101 are connected by a partition 103. A second motor 204 is provided in the middle of the bottom of the trolley 2. Two universal wheels 202 are symmetrically arranged on both sides of the second motor 204. The universal wheels 202 are supported on the crossbeam 101 and the longitudinal beam 102.

[0021] Since the top heights of the crossbeams 101 and 102 are the same and their cross-sectional dimensions are identical, the trolley can move easily. However, the partition 103 is lower than the crossbeams 101 and 102, so it is necessary to ensure the spraying of waterproof material in different partition areas with relatively high accuracy to avoid waste and unsightly spraying of material onto the partition. Furthermore, the waterproof material needs to be sprayed to a certain height to meet the design requirements.

[0022] The second motor 204 in this design starts and stops stably and quickly. The second motor 204 is fitted with a tire on its outer side, so only one drive wheel is needed to move the entire vehicle. The structure is stable, and even if the second motor 204 fails, it can still be pushed manually without the problem of excessive drag torque caused by the failure of the second motor 204, which would prevent it from moving. The whole vehicle will not become unstable. The omnidirectional wheels 202 ensure convenient turning, avoiding the disadvantages of using four fixed wheels, which make turning difficult and inconvenient.

[0023] In use, the size of the spraying area formed by the partition 103 is first set. While moving along the horizontal beam 101 or the vertical beam 102, the nozzle 305 reciprocates. Simultaneously, the nozzle 305 changes its position in a timely manner via the third motor 304 (the nozzle 305 gradually moves closer to the center of the spraying area). The height difference between the nozzle 305 and the spraying area is kept constant by adjusting the first telescopic cylinder 9, thus ensuring uniform spraying. Since the length of the square tube 302 is limited, when the already sprayed area exceeds the area to be sprayed (the sum of the already sprayed area and the area to be sprayed is the required spraying area), the spraying will be uneven. When the total area is reached, the trolley 2 is moved to one side of the area to be sprayed (i.e., opposite the already sprayed area) and sprayed again. The nozzle 305 is controlled by the third motor 304 to change its position in a timely manner (the position of the nozzle 305 gradually moves away from the center of the sprayed area), thereby completing the overall spraying. During this operation, the partition surface will not be covered (there may be cases where the spraying height is lower than the height of the partition 103), thus improving the aesthetics and quality of the spraying construction. If there are four corners or nooks and crannies, the square tube 302 can be rotated relative to the position of the adjusting rod 801 for touch-up spraying. The whole process completely avoids the defects of manual construction, which requires temporary standing in the spraying area and may cause some pollution to the sprayed area, thus ensuring the consistency of construction.

[0024] like Figure 7-10 In the preferred embodiment, the second motor 204 is connected to the trolley 2 via an L-shaped fixing frame 205, and a second telescopic cylinder 203 is provided between the two universal wheels 202 on both sides along the walking direction. The second telescopic cylinder 203 controls the state of the universal wheels 202 via a top rod 220. The bottom of the trolley 2 is also provided with a compartment 201, and the two sides of the second motor 204 are provided with output shafts 221, which are connected to the trolley 2 through an L-shaped fixing frame 205. A straightening assembly 6 is also provided, which includes a fourth motor 601 located inside the hopper 201. The four motors 601 are connected to swing plates 602 on both sides of the fourth motor 601 via couplings 605. The swing plates 602 are connected to the couplings 605 via connecting rods 606. A first step 604 is provided in the middle of the swing plate 602. Multiple balls 603 are hinged to the lower part of the swing plate 602. The balls 603 are attached to the outer side of the upper flip beam 1.

[0025] The second telescopic cylinder 203 can control the casters 202 at each position to work in different states, coordinating with the movement of the trolley 2 on the upper beam 1. At the same time, the compartment 201 plays a role in weight reduction, with strong overall rigidity and convenient movement. The casters 202 ensure convenient movement. The second telescopic cylinder 203 can coordinate the casters 202 at the four corners to switch between different states to meet the needs of straight lines or turns. It is easy to operate and has good performance. The coupling 605 adopts a telescopic structure, which can be adjusted within a certain range. Since the size of the upper beam 1 varies in different projects, during installation, the coupling 605 can be adjusted so that when the swing plate 602 is in a vertical state, the ball bearings 603 are in contact with the side wall of the upper beam 1, resulting in high overall movement accuracy. When the swing plate 602 is adjusted from a vertical state to a horizontal state, due to the rolling characteristics of the ball bearings 603, it moves smoothly at any angle on the side wall of the upper beam 1. At the same time, the two opposing swing plates 602 cooperate with each other to ensure that the trolley 2 stays in a straight line during movement. The first step 604 reduces the overall weight and avoids interference. When it is not necessary to straighten temporarily (i.e., when it is necessary to move at the corner of the crossbeam 101 and the longitudinal beam 101), the swing plate 602 is adjusted to a horizontal state, thereby disconnecting it from the upper beam 1.

[0026] In the preferred embodiment, the L-shaped fixing bracket 205 is provided with a first oblong hole 206 and a first threaded hole 207. The L-shaped fixing bracket 205 is connected to an adjusting seat 208 by a locking pin 212. The locking pin 212 passes through the first threaded hole 207. The adjusting seat 208 fits against the inner side of the L-shaped fixing bracket 205. The adjusting seat 208 is provided with a round hole 209, which is directly opposite the first oblong hole 206. The output shaft 221 passes through the round hole 209 and the first oblong hole 206. A first through hole 210 is provided through one side of the round hole 209. The first through hole 210 has countersunk holes 211 on its upper and lower sides, respectively. Two retaining rings 213 are provided parallel to each other at the end of the locking pin 212. The locking pin 212 passes through the first through hole 210, and the retaining rings 213 are located in the countersunk holes 211.

[0027] Since a tire is mounted on the second motor 204, and the tire pressure tends to decrease over time, it is necessary to adjust the contact area between the tire and the top surface of the upper beam 1. This can be achieved by changing the position of the adjusting seat 208 using the locking pin 212. The inner diameter of the round hole 209 matches the outer diameter of the output shaft 221, while the first oblong hole 206 provides a certain range of motion, ensuring safe use while also providing temporary clearance. This allows for height adjustment of the output shaft 221, facilitating stable and sufficient contact between the tire and the upper beam 1. When the second motor 204 malfunctions and cannot rotate, the overall drag torque is large, causing significant resistance to the movement of the trolley 2 due to the contact between the tire and the upper beam 1. By adjusting the position of the locking pin 212 with a wrench, the output shaft 221 can be moved upwards, suspending the tire and the second motor 204 from the top surface of the upper beam 1. The trolley 1 can still move smoothly, ensuring construction efficiency.

[0028] like Figure 11-12 In the preferred embodiment, the caster wheel 202 includes a bracket 214. The top of the bracket 214 is provided with a fixing rod 215. The fixing rod 215 passes through the bottom of the trolley 2 and is connected to the trolley 2 by a first nut 216. The bracket 214 is provided with notches 217 on both sides. The notches 217 include a small end 218 and a large end 219. The small end 218 is located on the side close to the fixing rod 215. The top rod 220 is located inside the notch 217, and the outer diameter of the top rod 220 matches the size of the small end 218.

[0029] The second telescopic cylinder 203 is a bidirectional telescopic cylinder, both of which are equipped with push rods 220. Since the push rods 220 only require a small range of telescopic movement, during use, it is necessary to ensure that the push rods 220 remain within the notch 217 when the casters 202 rotate. Because the size of the larger end 219 is larger than the outer diameter of the push rods 220, the casters 202, under the action of external force, only operate within a certain angular range. Simultaneously, the limiting effect of the push rods 220 prevents the problem of uncontrolled angular movement. When the casters 202 need to be repositioned as directional casters, the push rods 220 extend and abut against the smaller end 218 of the notch 217. Because the trolley 2 cannot turn around within the limited space of the upper tilting beam 1, This allows the system to switch between three states: all four casters 202 have a turning angle, only two casters 202 on any one side have a turning angle, and all four casters 202 are locked. This completes the overall reversing operation. Generally, placing the casters 202 with steering function on the rear side of the travel direction ensures more convenient operation and precise directional control, avoiding the problem of inconvenience or loss of directional control that may occur if the steering is placed on the front. Therefore, through the above operation, the trolley 2 can move more easily at the vertical corner where the crossbeam 101 and longitudinal beam 102 of the upper flip beam 1 meet, thereby improving the convenience of use.

[0030] When in use, when the construction quality on both sides of the upper beam 1 is relatively consistent, the four casters 202 are adjusted from a rotatable state to a fully locked state with only directional function, making movement stable and convenient. Since the upper beam 1 requires formwork for pouring during construction, there may be some unevenness between two adjacent formworks. At this time, the joint can be clearly seen on the outside of the upper beam 1. Therefore, the four casters 202 are adjusted to a state with a slight rotation angle. When the ball bearing 603 touches the joint, misalignment may occur, causing the trolley 2 to shift. The transition of movement at the joint can be completed by changing the rotation angle of the casters 202. The farther the distance between the top rod 220 of the second telescopic cylinder 203 and the small end 218, the larger the rotation angle of the casters 202, making it more flexible.

[0031] like Figure 13-17In the preferred embodiment, the lifting assembly 8 includes an adjusting rod 801, a groove 802 at the top of the adjusting rod 801, a connecting seat 301 and the groove 802 being inserted into each other, a square tube 302 and the connecting seat 301 being hinged together, a track ring 805 on the outer side of the adjusting rod 801, an arc-shaped slider 308 and the track ring 805 being slidably connected, the square tube 302 being connected to the arc-shaped slider 308 via a first telescopic cylinder 9, a rack 303 being meshed with a drive gear 322, the drive gear 322 being fixed inside the square tube 302 via a third motor 304, a third retainer 317 at the end of the rack 303, an ear plate 318 on the upper side of the nozzle 305, the ear plate 318 being hinged to the rack 303 via a first pin 321, a second threaded hole 319 penetrating through the third retainer 317, a second screw 320 located inside the second threaded hole 319, and the end of the second screw 320 abutting against the ear plate 318.

[0032] The lifting assembly 8 uses a hydraulic cylinder, which can change its height within a certain range to adjust the spraying range of the nozzle 305. When in use, for corners and crevices (such as the four corners formed by the partition 103, the crossbeam 101, and the total 102), the trolley 2 can be moved to the other side of the upper beam 1, and the angle of the connecting seat 301 and the adjusting rod 801 can be adjusted to complete the spraying. This avoids the defect of having to move the trolley 2 to change its own angle to complete the spraying. When the nozzle 305 is in use, it is hinged to the third bracket 317 of the square tube 302. At this time, the second screw 320 is needed to further lock it, so that the nozzle 305 can be adjusted in angle within a certain range to fully cover the construction area.

[0033] In the preferred embodiment, a plurality of locking grooves 803 are provided circumferentially inside the sink 802, and a fourth threaded hole 804 is provided through the locking groove 803. The bottom of the lifting assembly 8 is connected to the trolley 2 through the load-bearing plate 806. A plurality of first mounting holes 309 are evenly distributed on the outer side of the connecting seat 301. A positioning bead 310 is provided in the first mounting hole 309. The positioning bead 310 fits in the locking groove 803. The first screw 313 is located in the fourth threaded hole 804, and the end of the first screw 313 fits in the outer side of the connecting seat 301. The upper part of the connecting seat 301 is provided with a support column 311, the middle part of the support column 311 is provided with a through groove 312, the square tube 302 is hinged to the support column 311 through the first pin 321, and the end of the rack 303 is provided with a safety stop 314. The square tube 302 has a first mounting base 306 at its lower part, and a second mounting base 307 on one side of the arc-shaped slider 308. The first mounting base 306 and the second mounting base 307 are respectively hinged to the first telescopic cylinder 9. The square tube 302 has a counterweight 315 on the side away from the nozzle 305. A second mounting hole 316 is provided through one side of the rack 303. The output end of the third motor 304 is set directly opposite the second mounting hole 316.

[0034] The locking groove 803 on the adjusting rod 801 can capture the positioning bead 310, and simultaneously lock it in place with the second screw 320, ensuring stable adjustment. Eight locking grooves 803 are provided, allowing for rotation in single-step 45° adjustments, while maintaining ease of manufacturing and greater flexibility in use. The positioning bead 310 can extend and retract under external force to adjust itself. Because multiple positioning beads 310 work together during adjustment, the process is smooth and effective.

[0035] The adjusting rod 801 also serves to support and limit the square tube 303. Since the center of gravity of the lifting assembly 8 is relatively low, it can stably bear the load. The square tube 302 and the rack 303 are made of lightweight materials (such as carbon fiber or polytetrafluoroethylene, which have high overall structural strength and relatively light weight). The length change of the first telescopic cylinder 9 can change the angle of the square tube 302 itself. At the same time, in order to ensure the overall balance, a counterweight 315 is set to further improve the overall smoothness of movement. The forward and reverse rotation of the drive gear 322 cylinder changes the extension length of the rack 303. In conjunction with the first telescopic cylinder 9, the position can be adjusted while ensuring that the distance between the nozzle 305 and the bottom construction area of ​​the upper beam 1 is consistent, thus ensuring the quality of spraying. At the same time, the safety stop is set so that the rack 303 remains inside the square tube 302 without slipping when the third motor 304 is completely ineffective.

[0036] like Figure 18-24 In a preferred embodiment, the top of the cylinder 401 is provided with multiple evenly distributed strip plates 402. The ends of the multiple strip plates 402 are connected by a first ring plate 407. A first motor 10 is detachably installed on the first ring plate 407. A stirring rod 12 is installed at the bottom of the first motor 10. The stirring rod 12 includes a first blade 14, a second blade 1203, and a third blade 1204 installed sequentially from top to bottom along the axis. The first blade 14 and the third blade 1204 are inclined toward the top and bottom of the cylinder 401, respectively. The second blade 1203 is vertically arranged on the stirring rod 12. The end of the second blade 1203 is provided with multiple toothed openings 1205.

[0037] Driven by the first motor 10, the stirring rod 12 thoroughly stirs the mixture. The first blade 14 is tilted upward at an angle of 30-45°, and the third blade 1204 is tilted downward at an angle of 10-20°. Through the cooperation of the first blade 14, the second blade 1203, and the third blade 1204 at different positions, fluid ingredients of different densities can be thoroughly mixed, improving the mixing efficiency. At the same time, the toothed opening 1205 at the end of the second blade 1203 increases the shear force, thereby improving the mixing effect.

[0038] The banner plate 402 adopts a quick-release structure design, which can be installed and removed from the cylinder 401, thereby facilitating the maintenance of the stirring rod 12 and the scraping assembly 13 and avoiding the cumbersome use.

[0039] In a preferred embodiment, the scraping assembly 13 includes two opposing semi-ring plates 1301, with fixing plates 1303 at the ends of the two semi-ring plates 1301 respectively. The two adjacent fixing plates 1303 are connected, and the outer side of the semi-ring plate 1301 is attached to the inner side of the cylinder 401. The middle part of the two semi-ring plates 1301 is respectively connected to a docking ring 1305 and a circular ring 1306 through a first mounting bracket 1304. Two opposing banner plates 402 are respectively provided with a first mounting plate 403 and a second mounting plate 404, and the first mounting plate 403 and the second mounting plate 404 are respectively provided with a second through hole 405 and a third threaded hole 406. It also includes a lead screw 1314 and a fixing rod 1315. The lead screw 1314 passes through the second through hole 405 and is threadedly connected to the mating ring 1305. The fixing rod 1315 passes through the third threaded hole 406 and the ring 1306. The upper end of the lead screw 1314 is connected to the first mounting plate 403 through the fifth motor 1313. The upper side of the fixing rod 1315 is threadedly connected to the third threaded hole 406.

[0040] The scraping assembly 13 can scrape off the material remaining on the inner wall of the cylinder 401, ensuring cleanliness and preventing accumulation during the next mixing, thus affecting the mixing quality. The two semi-ring plates 1301 are installed stably. In the initial manufacturing state, a certain gap is maintained between the two adjacent fixing plates 1303, which can meet the subsequent adjustment and increase the thickness of the plug. At the same time, due to the possibility of deformation of the components after long-term use, the distance between the fixing plates 1303 can be adjusted by the plug, which can meet the scraping needs within a certain range and ensure that the tip 1302 of the semi-ring plate 1301 can be stably attached to the inner wall of the cylinder 401.

[0041] The lead screw 1314 acts as a drive and, together with the fixed rod 1315, acts as a guide. The forward and reverse rotation of the lead screw 1314 drives the semi-annular plate 1301 to move up and down smoothly and stably. At the same time, the semi-annular plate 1301 performs secondary mixing on the inner side of the cylinder 401. Usually, due to space limitations, the diameter of the blade of the stirring rod 12 is far from the side wall of the cylinder 401. At this time, the up and down movement of the semi-annular plate 1301 also plays the role of pushing and stirring the mixed fluid. The mixing actions at multiple positions work together to improve the overall mixing efficiency.

[0042] In the preferred embodiment, two support sleeves 411 are symmetrically distributed at the bottom of the cylinder 401. The lower parts of the screw 1314 and the fixing rod 1315 are located inside the support sleeves 411. The first mounting bracket 1304 is connected to the second mounting bracket 1308 on both sides by arc plates 1307. The second mounting bracket 1308 is provided with screws 1309 on both sides. The top of the screws 1309 is provided with a third nut 1310. The two screws 1309 are inserted into the pusher plate 1311. The pusher plate 1311 is symmetrically provided with two second oblong holes 1312. The screws 1309 are located in the second oblong holes 1312. The upper and lower sides of the semi-annular plate 1301 are provided with pointed heads 1302.

[0043] The support sleeve 411 ensures the rotational stability of the lead screw 1314 and the fixed rod 1315, while preventing displacement or deformation due to the impact of the mixed fluid during the mixing process. The fifth motor 1313 can adjust the height of the entire assembly after the two semi-ring plates 1301 are connected. At the same time, the pusher plate 1311 set on the semi-ring plate 1301 completes the upward pushing action of the lower mixed fluid during the up-and-down reciprocating motion, and flips it in the vertical direction. This ensures sufficient coordination in at least two directions, horizontal and vertical, resulting in high mixing efficiency. Since the second oblong hole 1312 of the pusher plate 1311 is located relatively high, under its own weight, the pusher plate 1311 is tilted downwards under the constraint of the screw 1309. As the pusher plate 1311 moves the mixed fluid from the top to the bottom, the mixed fluid provides upward support to the pusher plate 1311, causing it to gradually tilt upwards, further increasing the tumbling effect of the mixed fluid. Because the pusher plate 1311 can change angles, it can release pressure, avoiding excessive downward resistance that could cause significant impact on the cylinder 401 and other components. The multiple pusher plates 1311 interact with each other, working in conjunction with the stirring rod 12 to complete the overall mixing process, resulting in high mixing efficiency and ensuring the cleanliness of the inside of the cylinder 401.
