[0018] As Figures 1-6The utility model relates to a kind of stirring spraying device suitable for the construction of waterproof material of upper turning beam, including trolley 2 supported on upper turning beam 1, trolley 2 is equipped with spraying assembly 3 and stirring assembly 4, spraying assembly 3 includes spray head 303, stirring assembly 4 includes cylinder 401, the middle part and inner side of cylinder 401 are equipped with stirring rod 12 and scraping component 13 respectively, spray head 303 is connected by pipeline 5 and stirring assembly 4; Stirring rod 12 includes first blade 14, second blade 1203 and third blade 1204 installed in sequence from top to bottom along axis, first blade 14 and third blade 1204 are inclined to the top of cylinder 401 and the bottom of cylinder 401 respectively, second blade 1203 is vertically arranged on stirring rod 12, and the end of second blade 1203 is provided with a plurality of tooth-shaped openings 1205; Scraping component 13 includes two half ring plates 1301 oppositely arranged, and the two half ring plates 1301 are respectively attached to the inner side of cylinder 401, and the cylinder 401 is cleaned by the up-down movement of the half ring plate 1301.

[0019] During construction, the partition 103 of the upper turning beam 1 separates the construction area, which requires the tools to be moved back and forth in multiple areas during construction, and the overall construction amount is large, the labor intensity is high, and the overall construction efficiency is low, and the construction quality is difficult to guarantee, in order to solve the above problems, the beam body upper part of the upper turning beam 1 is used as a channel through the whole area, so that the trolley 1 walks on it, so that the mixed body with foaming effect is formed after the mixing of waterproof material by stirring assembly 4, the waterproof material is extracted from stirring assembly 4 by air compressor and pipeline 5, and then sprayed by spraying assembly 3, to ensure the quality and efficiency of construction.

[0020] Stirring rod 12 can complete stirring from different heights by setting three groups of blades, which improves the mixing efficiency, and scraping component 13 can scrape the fluid attached to the inner wall of cylinder 401, to ensure high material utilization and clean cylinder 401.

[0021] In the preferred scheme, the upper turning beam 1 includes a vertical cross beam 101 and a vertical longitudinal beam 102, the adjacent cross beams 101 are connected by partitions 103, the bottom of the trolley 2 is provided with a second motor 204, and two universal wheels 202 are symmetrically arranged on both sides of the second motor 204, and the universal wheels 202 are supported on the cross beam 101 and the longitudinal beam 102. The spraying assembly 3 comprises a handheld rod 301, a growth rod 302 telescopically arranged in the handheld rod 301, and a spray head 303 arranged at the end of the growth rod 302; the lower side of the handheld rod 301 is hingedly connected with a clamping seat 304, the bottom of the clamping seat 304 is provided with a supporting column 305, the supporting column 305 is inserted into a fixing frame 8, and the fixing frame 8 is detachably arranged on the top of the trolley 2.

[0022] The top of the cross beam 101 and the longitudinal beam 102 is consistent in height, and the cross section size is the same, so that the trolley is convenient to walk, and the partition 103 is lower in height compared with the cross beam 101 and the longitudinal beam 102, so that the spraying of the waterproof material in different partition areas needs to be accurately ensured, so as to avoid waste and poor appearance caused by spraying the waterproof material on the partition, and the waterproof material needs to be sprayed to a certain height to meet the design requirement.

[0023] The second motor 204 is stable and fast in starting and stopping, the outer side of the second motor 204 is sleeved with a tire, and only one driving wheel is needed to complete the walking of the trolley as a whole, and the structure is stable, even if the second motor 204 fails, the trolley can still be pushed by manpower, and the problem that the trolley cannot move due to too large dragging torque caused by failure of the second motor 204 does not occur, and the trolley also does not have the problem of instability, and the universal wheel 202 is arranged, so that the trolley is convenient to turn when moving, and the defect that it is difficult to turn and inconvenient to use due to the use of four directional wheels is avoided.

[0024] As shown in the preferred scheme in the specification, Figures 7-11 In the preferred scheme, the second motor 204 is connected with the trolley 2 through an L-shaped fixing frame 205, a second telescopic cylinder 203 is arranged between the two universal wheels 202 on the two sides in the walking direction, the state of the universal wheel 202 is controlled by the second telescopic cylinder 203 through a top rod 220, the bottom of the trolley 2 is further provided with a warehouse body 201, the two sides of the second motor 204 are provided with output shafts 221, the output shafts 221 are connected with the trolley 2 through the L-shaped fixing frame 205; The first waist round hole 206 and the first threaded hole 207 are arranged through the L-shaped fixing frame 205, the L-shaped fixing frame 205 is connected with an adjusting seat 208 through a lock pin 212, the lock pin 212 is arranged through the first threaded hole 207, the adjusting seat 208 is attached to the inner side of the L-shaped fixing frame 205, a round hole 209 is arranged through the adjusting seat 208, the round hole 209 is arranged opposite to the first waist round hole 206, the output shaft 221 is arranged through the round hole 209 and the first waist round hole 206, a first through hole 210 is arranged through one side of the round hole 209, the upper side and the lower side of the first through hole 210 are respectively provided with counterbores 211, the end of the lock pin 212 is parallelly provided with two retaining rings 213, the lock pin 212 is arranged through the first through hole 210, and the retaining rings 213 are located in the counterbores 211.

[0025] The universal wheel 202 at each position can work in different states through the second telescopic cylinder 203, and the trolley 2 walks on the turnover beam 1, and the warehouse body 201 plays a role of weight reduction, the whole rigidity is strong, and the trolley 2 is convenient to move, the universal wheel 202 at four corners can be cooperated through the second telescopic cylinder 203, and the trolley 2 can be switched between different states, so that the needs of straight line or turning are met, the operation is convenient, and the use effect is good.

[0026] Since the tire is installed on the second motor 204, the tire pressure has a certain pressure relief problem with the use of time, the contact area of the tire and the top surface of the turnover beam 1 needs to be adjusted, at this time, the position of the adjusting seat 208 can be changed, the position of the adjusting seat 208 can be changed through the lock pin 212, the inner diameter of the circular hole 209 matches the outer diameter of the output shaft 221, and the first waist circular hole 206 can provide a certain moving range, so that the safety use is guaranteed, and the temporary avoidance effect is achieved; so as to complete the height adjustment of the output shaft 221, the tire is stably and fully contacted with the turnover beam 1, when the second motor 204 fails to rotate, at this time, since the overall drag torque is large, the contact between the tire and the turnover beam 1 causes large resistance to the walking of the trolley 2, the position of the lock pin 212 is adjusted through the wrench, so that the output shaft 221 is completely moved upward, the tire and the second motor 204 are suspended and separated from the top surface of the turnover beam 1, and the trolley 1 still moves smoothly, so that the construction efficiency is guaranteed.

[0027] As Figures 11-14 In the preferred scheme, the universal wheel 202 comprises a support 214, the top of the support 214 is provided with a fixing rod 215, the fixing rod 215 is arranged in the bottom of the trolley 2, the fixing rod 215 is connected with the trolley 2 through a first nut 216, both sides of the support 214 are respectively provided with notches 217, the notches 217 comprise small ends 218 and large ends 219, the small ends 218 are located on the side close to the fixing rod 215, a top rod 220 is located in the notch 217, and the outer diameter of the top rod 220 matches the size of the small end 218; The righting assembly 6 is further arranged, the righting assembly 6 comprises a fourth motor 601, the fourth motor 601 is located in the warehouse body 201, swing plates 602 are connected to the fourth motor 601 through shaft couplings 605, a plurality of ball bearings 603 are hingedly arranged on the outer sides of the swing plates 602, and the ball bearings 603 are attached to the outer sides of the turnover beam 1. The anti-tilting assembly 7 is further arranged, the anti-tilting assembly 7 comprises two fixed cylinders 701 arranged oppositely, a pick plate 704 is telescopically arranged in the fixed cylinder 701, a pull rod 711 is arranged on the pick plate 704, a rubber wheel 714 is sleeved on the pull rod 711, and the rubber wheel 714 is used for stabilizing when the trolley 2 turns.

[0028] The second telescopic cylinder 203 is a bidirectional telescopic cylinder, both of which are provided with a top rod 220. Since the top rod 220 only needs a small telescopic change range, when in use, it is necessary to ensure that the top rod 220 is always in the gap 217 when the universal wheel 202 rotates. Since the size of the large end 219 is larger than the outer diameter of the top rod 220, when the universal wheel 202 is subjected to an external force, each universal wheel 202 only works within a certain angle range, and due to the limiting of the top rod 220, the problem of out-of-control rotation angle is avoided. When the universal wheel 202 needs to be displaced and the directional wheel is needed, the top rod 220 is extended and abuts against the small end 218 of the gap 217. Since the trolley 2 cannot complete the turn in the limited space of the turnover beam 1, the mutual cooperation of the second telescopic cylinders 203 on both sides can switch between the states that all four universal wheels 202 have a rotation angle, only two universal wheels 202 on one side have a rotation angle, and all four universal wheels 202 are locked, thereby completing the overall reversing operation. Generally, the universal wheel 202 with the steering function is arranged on the rear side of the walking direction, which can ensure that the overall pulling operation is more convenient and the direction control is accurate, and can avoid the problem that the steering is arranged in front, which may cause inconvenient operation or out-of-control direction. Therefore, through the above operation, the trolley 2 can walk at the vertical corner position where the cross beam 101 and the longitudinal beam 102 of the turnover beam 1 intersect, thereby improving the convenience of use.

[0029] When in use, when the construction quality on both sides of the turnover beam 1 is relatively consistent, the four universal wheels 202 are adjusted from the rotatable state to the state of being completely locked and only having a directional function. At this time, the walking is stable and convenient. Since the turnover beam 1 needs to be matched with the formwork for pouring during construction, there may be certain concave-convex changes between adjacent two formworks. At this time, the joint can be obviously seen on the outside of the turnover beam 1. Then, the four universal wheels 202 are adjusted to have a micro-rotation angle. When the ball 603 hits the joint, misalignment may occur, causing the trolley 2 to shift. The rotation angle change of the universal wheel 202 can complete the walking transition at the joint. 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 universal wheel 202, and the more flexible it is.

[0030] The shaft coupling 605 adopts a telescopic structure and can be adjusted within a certain range. Since the sizes of the upturned beams 1 of different projects are different, the shaft coupling 605 can be adjusted during installation, so that when the swing plate 602 is in a vertical state, the rolling balls 603 are attached to the side walls of the upturned beams 1, and the overall movement precision is high. When the swing plate 602 is adjusted from the vertical state to a horizontal state, due to the rolling characteristics of the rolling balls 603, the swing plate 602 moves smoothly at any angle of the side walls of the upturned beams 1, and the two swing plates 602 cooperate with each other to ensure that the trolley 2 is in a straight line state during movement. The first step 604 can reduce the overall weight and avoid interference. When temporary righting is not required (i.e., when movement is required at the corner of the cross beam 101 and the longitudinal beam 101), the swing plate 602 is adjusted to a horizontal state, so that the connection state with the upturned beam 1 is released.

[0031] When walking in a straight line, the righting assembly 6 can ensure the accurate movement of the trolley 2 and ensure the safety and stability of movement. However, when it is necessary to switch between the cross beam 101 and the longitudinal beam 102 of the upturned beam 1, the righting assembly 6 needs to be temporarily opened at this time, so that the overall has the risk of falling at the right angle. At this time, the pull rod 711 located near the construction spraying area is lowered. Since the pull rod 711 is located in the middle region of the two sides of the trolley 2, it is pointed out that the pull rod 711 is still a target base point when the trolley 2 is at the turning point, and plays a role of identification. When the pull rod 711 near the construction spraying area approaches the right angle, the trolley 2 turns, and the middle part of the trolley 2 passes through the most dangerous displacement area after the right angle turning point, and continues to turn up the pull rod 711 away from the construction spraying area. Since the rubber wheel 714 itself and the inner side of the upturned beam 1 have a certain interval, a sufficient gap is formed between the outer side of the upturned beam 1 and the rubber wheel 714 after the turning point. At this time, under the self-weight state, the rubber wheel 714 slides to the bottom of the pull rod 711 to continue to provide safety protection on the outside. The two pull rods 711 located on both sides of the trolley 2 cooperate with each other, and the relative position between the pull rod 711 and the upturned beam 1 can be adjusted. The rubber wheels 714 of the pull rods 711 on both sides have sufficient buffering and supporting, which can provide sufficient lateral supporting force when one side of the rubber wheel 714 and the upturned beam 1 are in contact in the inclined state, so as to avoid the risk of complete tilting and falling of the trolley 2 from the upturned beam 1.

[0032] In the preferred scheme, the swing plate 602 is connected through the butt joint rod 606 and the shaft coupling 605, and the first step 604 is arranged in the middle of the swing plate 602. The fixed cylinder 701 is fixed on the top of the trolley 2, and the fixed cylinder 701 is provided with a through groove 702 and a first threaded opening 703 on both sides, respectively. The pick plate 704 is slidably arranged in the through groove 702, and the plug column 707 is located in the first threaded opening 703. The end of the plug column 707 is connected with the first spring 708, and the first spring 708 is provided with a lock ring 709 on one side. The end of the pick plate 704 is connected with the lock disc 706 through the transition rod 705, and the lock ring 709 is sleeved on the transition rod 705. The pick plate 704 comprises a bearing part 710, and a third through hole 715 is penetratingly arranged on the bearing part 710. The pull rod 711 is located in the third through hole 715, and the bottom of the pull rod 711 is provided with a stop disc 713. The pull rod 711 is connected with the pick plate 704 through the second nut 712 on both sides.

[0033] The extension range of the pick plate 704 can be adjusted by the position of the plug column 707 relative to the first threaded opening 703 of the fixed cylinder 701, which ensures the overall elastic locking force and meets the walking needs of the upturned beam 1 of different widths. In addition, the cross section of the through groove 702 is rectangular, and the lock ring 709 is sleeved on the transition rod 705, so that during the rotation of the plug column 707, the first spring 708 will not be twisted and deformed. The first spring 708 is always in an axial stress state, the overall elastic deformation is stable, the working efficiency is high, and the first spring 708 can be timely disassembled or replaced according to needs. Since the first spring 708 is initially in a natural length state, when the trolley 2 passes through the right-angle bend point, there is a vacuum period of the pull rod 711 that needs to be pulled away from the construction spraying area. At this time, the pull rod 711 is pulled apart by external force, and then enters the outside of the upturned beam 1 again, ensuring that the rubber wheel 714 is in contact with the upturned beam 1, ensuring the safety of the trolley 2 displacement. Since the trolley has a certain weight, applying external force to the pick plate 704 and the pull rod 711 will not cause the trolley 2 to move.

[0034] As Figures 15-22 In the preferred scheme, the top of the cylinder body 401 is provided with a plurality of evenly distributed banner plates 402, and the ends of the plurality of banner plates 402 are connected through a first ring plate 407. The first ring plate 407 is detachably installed with a first motor 10, and a stirring rod 12 is installed at the bottom of the first motor 10. The ends of the two half ring plates 1301 are respectively provided with fixed plates 1303, and adjacent two fixed plates 1303 are connected. The outer side of the half ring plate 1301 is attached to the inner side of the cylinder body 401. The middle parts of the two half ring plates 1301 are respectively connected with a butt joint ring 1305 and a circular ring 1306 through a first mounting bracket 1304. Among them, the first installation disc 403 and the second installation disc 404 are respectively arranged on two opposite banner plates 402, and the second through hole 405 and the third threaded hole 406 are respectively arranged on the first installation disc 403 and the second installation disc 404. 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] In the preferred embodiment, the bottom of the barrel 401 is symmetrically provided with two support sleeves 411, the lower part of the screw rod 1314 and the fixed rod 1315 is located in the support sleeve 411, the two sides of the first mounting frame 1304 are respectively connected with the second mounting frame 1308 through the arc plate 1307, the two sides of the second mounting frame 1308 are respectively provided with the screw rod 1309, the top of the screw rod 1309 is provided with the third nut 1310, the two screw rods 1309 are inserted in the push flow plate 1311, the push flow plate 1311 is symmetrically provided with two second waist round holes 1312, the screw rod 1309 is located in the second waist round hole 1312, and the upper side and the lower side of the half ring plate 1301 are respectively provided with the sharp head 1302.

[0040] The rotation stability of the screw rod 1314 and the fixed rod 1315 can be ensured through the support sleeve 411, and the problems of displacement or deformation caused by the impact of the mixed fluid during the mixing process are avoided, the overall height of the two half ring plates 1301 connected by the fifth motor 1313 can be adjusted, and the push flow plate 1311 provided on the half ring plate 1301 can complete the upward pushing action of the lower mixed fluid during the up-down reciprocating movement, and the mixed fluid is turned in the vertical direction, so that the mixed fluid is sufficiently mixed in at least two directions of the horizontal plane and the vertical plane, and the mixing efficiency is high. Since the second waist round hole 1312 of the push flow plate 1311 is located at a relatively high position, under the self-weight state, the push flow plate 1311 is in an inclined downward state under the limiting of the screw rod 1309, when the push flow plate 1311 moves from the top to the bottom, the mixed fluid provides an upward supporting force to the push flow plate 1311, so that the push flow plate 1311 is gradually turned upward from the downward inclined state, thereby further increasing the turning action of the mixed fluid. The push flow plate 1311 can change the angle, so it can release the force, avoid the problem that the barrel 401 and the components bear a large impact due to the excessive downward resistance, and the multiple push flow plates 1311 interact with each other to complete the overall mixing with the stirring rod 12, thereby improving the mixing efficiency and ensuring the cleanliness of the barrel 401.
