Description

Technical Field

[0001] The present invention relates to the technical field of building auxiliary equipment, and in particular to a device and method for vertically laying a dust-proof net for green construction of assembled buildings. Background Art

[0002] Dust-proof nets, also known as windbreaks and dust suppression nets, are made of high-density polyethylene (HDPE) and woven into a mesh using a special process. Used as coal yard walls, they prevent dust, block wind, and suppress the spread of dust. They are an environmentally friendly project for controlling dust pollution in open-air material yards. Dust-proof nets utilize aerodynamic principles and are processed into specific geometric shapes, with varying mesh opening ratios and hole shapes, based on the results of on-site environmental wind tunnel tests. This allows air to flow through the wall from the outside, creating an upward and downward interfering airflow inside the wall, creating a strong wind on the outside, a weak wind on the inside, or a light wind on the outside, with no wind on the inside, thus preventing the spread of dust.

[0003] At present, most of the dust-proof nets used in construction on the market are laid manually. The edges of the dust-proof nets are very easy to bend during laying. The bent dust-proof nets cannot remain perpendicular to the ground during laying, which is not conducive to the sewing of the dust-proof nets, delaying the construction progress. It is also dangerous for workers to lay the dust-proof nets for construction. Summary of the Invention

[0018] Step 1: In the initial state, the movable sleeve is connected to the winding roller, and the end of the belt with the dustproof net is fixed on the winding roller.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0040] See also Figures 1 to 10 In an embodiment of the present invention, a vertical laying device for a dust-proof net for green construction of an assembled building includes a base 1, two sets of support plates 5 are rotatably mounted on the base 1, a winding roller 11 and a lifting roller 9 are installed between the two sets of support plates 5, and a vertical plate 2 is fixedly provided on the base 1;

[0041] Specifically, the lower end of the support plate 5 is rotatably connected to a fixing member fixedly disposed on the base 1 so that the support plate 5 can be deflected relative to the base 1. In particular, see Figure 1 、 Figure 2 、 Figure 9 、 Figure 10, multiple groups of fixing rods 32 are equidistantly arranged on the above-mentioned winding roller 11 and the lifting roller 9. The dust-proof net itself has a porous structure. When laying the dust-proof net, the holes at the end of the dust-proof net are sleeved on the fixing rods 32, and it is tied with a cable tie to fix the end of the dust-proof net to the winding roller 11. After the dust-proof net to be laid is evenly rolled up onto the winding roller 11, the end of the dust-proof net is connected to the lifting roller 9. The dust-proof net can be pulled to the pre-laying height by lifting and lowering the lifting roller 9.

[0042] A vertical deflection mechanism is provided on the base 1 and includes a deflection assembly, a lifting assembly, and a linkage assembly. The lifting assembly is provided on the support plate 5 and connected to the lifting roller 9. The deflection assembly includes a driving member that is rotatably provided on the base 1. The linkage assembly connects the lifting assembly and the driving member. When the driving member drives the support plate 5 to deflect relative to the base 1, the linkage assembly is actuated to drive the lifting structure to drive the lifting roller 9 to rise and fall along the vertical direction of the support plate 5.

[0043] The deflection assembly further includes a screw rod 14 rotatably mounted on the base 1 , a threaded sleeve 13 threadedly connected to the screw rod 14 , a hinged rod 15 hinged to the threaded sleeve 13 , and an end of the hinged rod 15 away from the threaded sleeve 13 is hinged to the support plate 5 ;

[0044] See also Figure 1 、 Figure 2 The above-mentioned deflection components are provided with two groups, which are respectively connected to the two groups of support plates 5, and the above-mentioned two groups of screw rods 14 are connected by a transmission belt 12 so that the two groups of screw rods 14 can rotate at the same time. When the screw rod 14 rotates, the threaded sleeve 13 hinged to the support plate 5 through the hinge rod 15 gradually moves away from or approaches the support plate 5, driving the two groups of support plates 5 to deflect at the same angle, so that the two groups of support plates 5 always remain parallel.

[0045] The driving member includes a docking rod 25 rotatably mounted on the base 1 , and the docking rod 25 is connected to the screw rod 14 via a bevel gear set 28 ;

[0046] See also Figure 4 The docking rod 25 is rotatably connected to a fixing member fixedly mounted on the base 1, and the bevel gear set 28 includes a No. 1 bevel gear and a No. 2 bevel gear. The No. 1 bevel gear is coaxially fixed to the docking rod 25, and the No. 2 bevel gear is coaxially fixed to the screw rod 14. When the docking rod 25 rotates, the No. 1 bevel gear and the No. 2 bevel gear enter a transmission state. At this time, under the connection action of the transmission belt 12, the two sets of screw rods 14 rotate simultaneously to drive the threaded sleeve 13 and the screw rod 14 to slide relative to each other. During sliding, the hinged rod 15 can pull or push the support plate 5 to deflect.

[0047] The construction site dustproof net is made of high-density polyethylene as the raw material, woven into a mesh by a special process, and used as a coal yard fence to prevent dust, block the wind and suppress the flying of dust. In order to meet the large-area paving of floor buildings on the construction site, it is usually necessary to lay multiple dustproof nets and sew the two adjacent dustproof nets together. Since the mesh dustproof net has a certain flexibility, the edge of the dustproof net is very easy to bend during laying and suturing, which greatly reduces the laying of the dustproof net. In the embodiment of the present invention, in the initial state, the above-mentioned support plate 5 and the screw rod are 14 forms a certain angle. When in use, after the dust-proof net is laid and completely rolled up onto the winding roller 11, the end of the dust-proof net is fixed on the lifting roller 9, and the docking rod 25 is driven to rotate. At this time, under the action of the above-mentioned linkage assembly, the deflection assembly and the lifting assembly act at the same time. When the lifting assembly drives the lifting roller 9 to rise, the deflection assembly acts to enable the support plate 5 to deflect toward the screw rod 14, so that the dust-proof net connecting the lifting roller 9 and the winding roller 11 is perpendicular to the ground, so that the dust-proof net can be laid vertically.

[0048] Furthermore, the lifting structure includes a sheave 10 rotatably mounted on the support plate 5, and two groups of sheaves 10 are provided along the vertical direction of the support plate 5. Cables 6 are provided on the two groups of sheaves 10, and sliders 8 fixedly connected to the lifting rollers 9 are provided on the cables 6.

[0049] See also Figure 1 、 Figure 9 One end of the cable 6 is fixed to the slider 8, and the other end is slidably connected to the slider 8. When the cable 6 rotates, the slider 8 can move simultaneously with the cable 6, thereby driving the lifting roller 9 to rise or fall in the slide groove 7 opened on the support plate 5.

[0050] In an embodiment of the present invention, when the docking rod 25 rotates, the linkage assembly is activated, which can drive the groove wheel 10 to rotate, thereby causing the lifting roller 9 to rise. When rising, the winding roller 11 reverses to release the dustproof net. By utilizing the cooperation between the lifting roller 9 and the winding roller 11, the dustproof net can be tightened to avoid bending of the edge of the dustproof net, which is conducive to the sewing and splicing of multiple dustproof nets.

[0051] For further information, see Figure 7 、 Figure 8 , the linkage assembly includes a third belt 17 connecting the docking rod 25 and the groove wheel 10, and the third belt 17 is provided with an elastic telescopic structure;

[0052] The elastic telescopic structure includes a fixed sleeve 29, a telescopic rod 30 is slidably provided in the fixed sleeve 29, and a pulley is rotatably installed at one end of the telescopic rod 30 away from the fixed sleeve 29, and the pulley is connected to the third belt 17;

[0053] The above-mentioned fixed sleeve 29 is fixedly mounted on the support member 16 set on the base 1, and a spring 31 is slidably set in the fixed sleeve 29, one end of the spring 31 abuts against the telescopic rod 30, and the other end abuts against the fixed sleeve 29. In the initial state, the above-mentioned spring 31 is in a pulled-up state, and the support plate 5 deflects in the direction away from the screw rod 14. When the support plate 5 deflects toward the screw rod 14, the spring 31 retracts, and the No. 3 belt 17 is always in a taut state, so that the pulley, the docking rod 25 and the groove wheel 10 maintain a rotational connection.

[0054] In an embodiment of the present invention, when laying the dustproof net, it is necessary to fix the end of the dustproof net wound on the winding roller 11 on the lifting roller 9. Through the vertical deflection mechanism arranged on the base 1, when the docking rod 25 drives the screw rod 14 to rotate and the support plate 5 is deflected toward the screw rod 14, the linkage assembly is used to drive the lifting structure to move and lift the lifting roller 9 to the highest point. At this time, the dustproof net connecting the lifting roller 9 and the winding roller 11 is perpendicular to the ground. At this time, multiple people can operate at the same time and stand inside the floor to fix the dustproof net to the floor, which solves the problems of low efficiency and danger caused by general manual laying of dustproof nets, thereby improving the work efficiency of workers and accelerating construction efficiency.

[0055] As an embodiment of the present invention, please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , a vertical laying device for dust-proof nets for green construction of assembled buildings also includes a gear adjustment component, which is arranged on the base 1 and includes a gear member installed on the support plate 5, and the gear member can be connected to the driving member and the winding roller 11 respectively;

[0056] The gear adjustment assembly further includes a driving shaft 22 rotatably mounted on the vertical plate 2, the driving shaft 22 being fixedly connected to the output shaft of the motor fixedly mounted on the vertical plate 2, a sleeve 24 being slidably mounted on the driving shaft 22, and a connecting structure for connecting to the gear member being provided on the sleeve 24;

[0057] The shift member includes a movable sleeve 3 mounted on the support plate 5, and the movable sleeve 3 is connected to the winding roller 11;

[0058] For details, please refer to Figure 6 、 Figure 10The end of the winding roller 11 facing the movable sleeve 3 is formed with a docking head 33, and the docking head 33 is adapted to the docking groove 26 provided inside the movable sleeve 3, and a hollow groove 27 connected to the docking groove 26 is also provided inside the movable sleeve 3. In the initial state, the docking head 33 is engaged with the docking groove 26. At this time, the winding roller 11 rotates simultaneously with the movable sleeve 3 to rewind the dustproof net onto the winding roller 11; after the winding is completed, the movable sleeve 3 is pushed toward the winding roller 11, and the docking head 33 is separated from the docking groove 26 and placed in the hollow groove 27. At this time, the winding roller 11 is rotationally connected to the movable sleeve 3, so that the winding roller 11 can rotate relative to the movable sleeve 3 to release the dustproof net.

[0059] The connecting structure includes a No. 2 connecting plate 18 rotatably connected to the sleeve 24, a rotating member 19 is installed at one end of the No. 2 connecting plate 18 away from the sleeve 24, a No. 1 connecting plate 4 is rotatably installed on the rotating member 19, and the No. 1 connecting plate 4 is rotatably connected to the movable sleeve 3 at one end away from the rotating member 19, and the movable sleeve 3 is connected to the rotating member 19 via a No. 1 belt 20, and the sleeve 24 is connected to the rotating member 19 via a No. 2 belt 21;

[0060] For details, please refer to Figure 3 、 Figure 4 、 Figure 5 , one end where the No. 2 connecting plate 18 is connected to the socket tube 24 is provided with a Y-shaped socket part 23, and the Y-shaped socket part 23 is connected to the cylinder on which the vertical plate 2 is installed. When the cylinder is actuated, the Y-shaped socket part 23 can be driven away from or close to the vertical plate 2. In the initial state, when the cylinder is driven to push the socket tube 24 away from the vertical plate 2, the socket tube 24 connects the docking rod 25 to the active shaft 22. At this time, under the connection between the No. 1 connecting plate 4 and the No. 2 connecting plate 18, the movable sleeve 3 moves toward the winding roller 11, and the two are transformed from a fixed connection state to a rotating connection state. The vertical laying device for the dust-proof net for green construction of prefabricated buildings switches from a winding state to a vertical laying state.

[0061] In the embodiment of the present invention, in the initial state, the sleeve 24 is only connected to the active shaft 22, and the docking joint 33 of the winding roller 11 is engaged with the docking groove 26 of the movable sleeve 3. At this time, the motor is started, the active shaft 22 drives the sleeve 24 to rotate, and the No. 2 belt 21 connected to the sleeve 24 enters the transmission state, driving the rotating member 19 to rotate, and then the No. 1 belt 20 enters the transmission state, and the movable sleeve 3 drives the winding roller 11 to rotate to reel the dustproof net onto the winding roller 11. After the dustproof net is completely reeled onto the winding roller 11; the cylinder is driven to move, so that the Y-shaped sleeve 23 moves away from the vertical plate 2, so that the sleeve 24 is connected to the docking rod 25. At this time, the sleeve 24, the docking rod 25 and the active shaft 22 are connected at the same time. When the active shaft 22 rotates, the docking rod 25 rotates, and the deflection assembly and the lifting assembly act at the same time under the action of the linkage assembly, and the dustproof net wound onto the winding roller 11 is laid vertically to the side of the floor.

[0062] As an embodiment of the present invention, a method for vertically laying a dust-proof net for green construction of an assembled building is also proposed, which uses the device for vertically laying a dust-proof net for green construction of an assembled building, comprising the following steps:

[0063] Step 1: In the initial state, the movable sleeve 3 is connected to the winding roller 11, and one end of the belt with the dustproof net is fixed to the winding roller 11. Then, the motor is started, and the driving shaft 22 rotates, so that the No. 1 belt 20 and the No. 2 belt 21 enter a continuous transmission state. At this time, the movable sleeve 3 can drive the winding roller 11 to store the dustproof net on the winding roller 11;

[0064] Step 2: When the dust screen is completely rolled up onto the winding roller 11, the motor is turned off and the movable sleeve 3 is pushed toward the winding roller 11. At this time, the movable sleeve 3 is rotationally connected to the winding roller 11, and the sleeve 24 is connected to the docking rod 25 and the driving shaft 22. Then, the motor is started again, the docking rod 25 rotates, and the bevel gear set 28 enters the transmission state;

[0065] Step 3: The bevel gear set 28 continues to rotate, and the screw rod 14 drives the threaded sleeve 13 to gradually move away from the support plate 5. At this time, the hinged rod 15 pulls the support plate 5 toward the threaded sleeve 13 to deflect;

[0066] Step 4: During the deflection of the support plate 5, the telescopic rod 30 retracts into the fixed sleeve 29, and the No. 3 belt 17 always maintains the transmission state, which can drive the groove wheel 10 to rotate, and then drive the cable 6 to drive the lifting roller 9 to rise. After reaching the predetermined height, the motor is turned off and the dust screen is laid vertically;

[0067] Step 5: After the laying is completed, start the motor to reverse and make the lifting roller 9 fall back to the initial position, repeat steps 1, 2, 3, and 4 to carry out the second laying of the dustproof net.

7. A method for vertically laying dust-proof nets for green construction of prefabricated buildings, characterized in that: The vertical laying device for the dust-proof net for green construction of prefabricated buildings according to claim 6 comprises the following steps: Step 1: In the initial state, the movable sleeve (3) is connected to the winding roller (11), and one end of the belt with the dust-proof net is fixed on the winding roller (11). Then, the motor is started, and the driving shaft (22) rotates, so that the No. 1 belt (20) and the No. 2 belt (21) enter a continuous transmission state. At this time, the movable sleeve (3) can drive the winding roller (11) to store the dust-proof net on the winding roller (11); Step 2: When the dust screen is completely rolled up onto the winding roller (11), the motor is turned off and the movable sleeve (3) is pushed toward the winding roller (11). At this time, the movable sleeve (3) is connected to the winding roller (11) in rotation, and the sleeve (24) is connected to the docking rod (25) and the driving shaft (22). Then, the motor is started again, the docking rod (25) rotates, and the bevel gear set (28) enters the transmission state; Step 3: The bevel gear set (28) continues to rotate, and the screw rod (14) drives the threaded sleeve (13) to gradually move away from the support plate (5). At this time, the hinged rod (15) pulls the support plate (5) toward the threaded sleeve (13) to deflect; Step 4: When the support plate (5) deflects, the telescopic rod (30) retracts into the fixed sleeve (29), and the No. 3 belt (17) always maintains the transmission state, which can drive the groove wheel (10) to rotate, thereby driving the cable (6) to drive the lifting roller (9) to rise until it reaches the predetermined height, and then the motor is turned off to vertically lay the dust screen; Step 5: After the laying is completed, start the motor to reverse and make the lifting roller (9) fall back to the initial position, repeat steps 1, 2, 3 and 4, and the dustproof net can be laid for the second time.
