Abstract
Description
Technical Field
[0001] This invention relates to the field of dust suppression spraying, and more particularly to an automatic dust suppression spraying device specifically designed for aerial building construction machines.
[0002] The present invention also relates to a method of using the above-mentioned automatic sprinkler dust suppression device for aerial building construction machines. Background Technology
[0003] The aerial building machine is a large-scale, intelligently controlled, modular mechanical equipment platform. It can replace suspended platforms and climbing scaffolds, resulting in more stable and safer exterior wall construction. Equipped with a large curtain and sprinkler system, it creates a shaded, rainproof, and dust-reducing working environment for workers, ensuring construction quality, safety, progress, and occupational health.
[0004] A search revealed that Chinese utility model patent CN215352703U discloses a dust suppression spraying device based on a self-elevating building platform. During use, the angle of the spray nozzle can be adjusted within a certain range by the action of the mating teeth and rotating teeth, thereby making its working range larger. At the same time, the position of the spray nozzle can be adjusted by the action of the guide groove and guide block, so that the spraying device can spray different positions.
[0005] The aforementioned dust suppression spraying device for the building construction machine achieves a wide spraying range by adjusting the angle of the nozzles within a certain range. However, in actual operation, it has certain drawbacks. For example, the dust suppression spraying components lack storage and height adjustment functions. Due to the extensive space of the building construction machine, a certain number of spray nozzles and pipes need to be installed in the machine area to improve its dust suppression performance. This spraying facility occupies construction space and is prone to collision with construction materials transported in the steel frame passage. Moreover, adjusting the angle alone cannot completely treat dust in some blind spots, which still has certain shortcomings. Furthermore, when the spraying end is too high, combined with the airflow at high altitude, the water droplets cannot come into contact with dust in the air. When the spraying end is too low, it can easily affect the normal construction work of the workers. Summary of the Invention
[0006] The purpose of this invention is to provide an automatic spray dust suppression device for aerial building construction machines. It can provide shade and cooling, and can be deployed and retracted. When deployed, the spray dust suppression component can be lowered to spray dust. The spray water is sprayed under shaded conditions, which can avoid direct sunlight and prevent the spray water temperature from being too high, which is not conducive to cooling. When retracted, the spray dust suppression component can be raised to avoid obstructing the transportation of construction materials.
[0007] Another object of the present invention is to provide a method of using the above-mentioned automatic sprinkler dust suppression device for aerial building construction machines.
[0008] Regarding the technical topic of an automatic sprinkler dust suppression device specifically designed for aerial building construction machines, it includes:
[0009] There are two crossbeams, and T-shaped grooves extending along their axial direction are opened on their inner sides;
[0010] The sunshade cloth is spaced above the crossbeam;
[0011] The U-shaped bracket is set between two crossbeams and multiple brackets are spaced apart along the crossbeams. It has two vertical support plates and a top horizontal plate. The outer side of the vertical support plates is provided with T-shaped sliders that slide and adapt to the T-shaped grooves.
[0012] A connecting frame, which is spaced apart and installed on the top horizontal plate of the U-shaped bracket, with the sunshade cloth installed on its top;
[0013] The dust suppression spray assembly 7 is located below the shade cloth. It includes a hinge seat between adjacent U-shaped supports, with grooves on both sides of the hinge seat. A pin is installed in the groove and the upper end of a connecting rod passes through the pin. A notch is provided on the side of the top crossbar of the U-shaped support, and a pin is also installed in the notch and passes through the lower end of the connecting rod. The hinge seat is fixedly sleeved with a spray pipe, and the upper end of the spray pipe is connected to a horizontal water injection pipe. Multiple corrugated pipes are spaced apart on the water injection pipe.
[0014] With this structure, the operator can control the unfolding and retraction of the spray dust suppression component 7 by moving the U-shaped bracket. The sunshade cloth can also be unfolded and retracted together for easy storage.
[0015] When deployed, the dust suppression spray unit descends and is released from its retracted state, signaling the operator to control the water pump to supply water from the water tank, which also facilitates lowering the spray height. When retracted, the operator controls the water pump to stop the water flow, and after the remaining water has drained, the operator operates the U-shaped bracket to move to one side to retract the dust suppression spray unit. After the dust suppression spray unit is retracted and raised, the operator signals to the construction personnel that the spraying process is over.
[0016] As a further improvement to the automatic sprinkler dust suppression device for aerial building construction machines, an X-shaped frame is hinged between the two U-shaped supports at the beginning and end. The X-shaped frame uses multiple diagonal bars stacked in a cross pattern, with the ends and middle of the diagonal bars hinged and fixed.
[0017] With this structure, the X-frame can control the opening and closing distance between the two U-shaped supports at the beginning and end, thereby controlling the overall opening and closing size. This prevents the connecting rod from tilting downwards after being pulled flat, causing the water injection pipe to collide with the U-shaped support and easily damage the water injection pipe.
[0018] As a further improvement to the automatic spray dust suppression device for aerial building construction machines, a propulsion assembly is installed on the vertical support plate of the outermost U-shaped bracket. The propulsion assembly includes toothed plates fixed to the top of two crossbeams; drive gears are meshed on the toothed plates, and a transmission shaft is coaxially fixed to the toothed plates. The transmission shaft slides through the vertical support plate of the U-shaped bracket; a motor is installed on the bottom surface of the top crossbar of the U-shaped bracket, and the output shaft of the motor is connected to the transmission shaft through a transmission assembly.
[0019] This structure, using an electric motor, facilitates manual operation and makes the entire operation process less strenuous.
[0020] As a further improvement to the automatic spray dust suppression device for aerial building construction machines, the transmission component is a sprocket drive component, a belt drive component, or a gear drive component.
[0021] As a further improvement to the automatic sprinkler dust suppression device for aerial building construction machines, the sprinkler pipe has a fixed sealing ring inside, an extension pipe is sleeved in the sealing ring, and a sprinkler nozzle is connected to both sides of the extension pipe. The lower end of the sprinkler pipe is threaded with a bolt, and the bolt is tightened against the extension pipe.
[0022] With this structure, the extension tube can be secured.
[0023] As a further improvement to the automatic sprinkler dust suppression device for aerial building construction machines, the lower end of the extension pipe is connected to one end of a telescopic hose, and the other end of the telescopic hose is connected to a sprinkler valve nozzle.
[0024] With this structure, the telescopic hose is easy to operate by hand.
[0025] As a further improvement to the automatic sprinkler dust suppression device for aerial building construction machines, the sprinkler pipe is slidably connected to a sliding block, a protrusion is provided on one side of the sliding block, and a suspension latch is provided on the protrusion. The suspension latch is semi-closed to lock the telescopic hose.
[0026] This structure allows the flexible hose to be locked in the suspension bayonet when not in use.
[0027] As a further improvement to the automatic sprinkler dust suppression device for aerial building construction machines, a tension spring is fixedly connected between the sliding block and the hinge seat.
[0028] With this structure, after the sliding block is pulled down, it can be reset by the tension spring. After the suspension latch locks the spray valve nozzle, it can be reset and the telescopic hose can be raised again.
[0029] Regarding the technical topic of how to use the automatic sprinkler dust suppression device specifically designed for aerial building construction machines, the specific steps are as follows:
[0030] S1: Install crossbeams on the steel frame of the building construction machine;
[0031] S2: Install the remaining components on the basis of the crossbeam;
[0032] S3: The water injection pipe is connected to the water pump, and the water pump is connected to the water tank;
[0033] S4: Start the motor to rotate forward, unfold the sunshade and dust suppression spray assembly, and start the water pump to spray water;
[0034] S5: After the spraying is finished, start the motor to reverse so as to retract the sunshade cloth and the dust suppression spraying components.
[0035] This method facilitates dust suppression through spraying.
[0036] As a further improvement to the method of use, in S1, the crossbeam extends above the concrete.
[0037] In S3, the water tank and water pump are provided with sunshade measures so that the water pipes, water tank, and water pump are all provided with sunshade measures.
[0038] In S4, the spray nozzle is closed to automatically water and cure the concrete, or the operator can pull down the sliding block to detach the telescopic hose from the suspension clamp and hold the spray nozzle to water and cure the concrete.
[0039] This method is beneficial for watering and curing concrete. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0057] Example 1
[0058] Reference Figures 1-11 As shown, an automatic sprinkler dust suppression device for aerial building construction machines includes two crossbeams 1 fixedly installed on the steel frame platform of the construction machine. Sunshade cloths 2 are spaced apart above the two crossbeams 1. Several U-shaped supports 3 are arranged between the two crossbeams 1, and connecting frames 5 are fixedly connected to both ends of each U-shaped support 3. The sunshade cloths 2 are all fixed to the top of the connecting frames 5.
[0059] By installing a sunshade 2, the area above the aerial building machine is protected, providing sunshade and wind protection, thereby improving the comfort of the workers' working environment.
[0060] At least one set of spray dust suppression components 7 is provided between two adjacent U-shaped supports 3; the two vertical support plates of the U-shaped support 3 are slidably connected to the inner side of the crossbeam 1, the inner side of the crossbeam 1 is provided with a T-shaped groove 4, and the outer side of the two vertical support plates of the U-shaped support 3 is provided with a T-shaped slider that is slidably adapted to the T-shaped groove 4.
[0061] A propulsion assembly 8 is installed on the vertical support plate of the outermost U-shaped bracket 3 to travel along the axial direction of the crossbeam 1;
[0062] Reference Figure 3The propulsion assembly 8 includes a toothed plate 81 fixed to the top of two crossbeams 1; a drive gear 82 meshes on the toothed plate 81, and the toothed plate 81 is coaxially fixed to a transmission shaft 83, which slides through the vertical support plate of the U-shaped bracket 3; a motor 84 is mounted on the bottom surface of the top crossbar of the U-shaped bracket 3, and the motor 84 can be a motor that can realize forward and reverse rotation, such as a stepper motor, and is driven by a corresponding control system, such as a remote control; the output shaft of the motor 84 is connected to the transmission shaft 83 through a transmission assembly, which is a sprocket transmission assembly, a belt transmission assembly, or a gear transmission assembly.
[0063] By advancing component 8, the outermost U-shaped support 3 can be moved. Since the sunshade cloth 2 is installed on multiple spaced U-shaped supports 3, when the outermost U-shaped support 3 moves, it is easy to fold or unfold the sunshade cloth 2 and the spray dust suppression component 7.
[0064] Reference Figure 3 and Figure 5 As shown, an X-shaped frame 6 is hinged between the two U-shaped supports 3 at the beginning and end. The X-shaped frame 6 uses multiple diagonal bars stacked in a crisscross pattern, with the ends and middle of the diagonal bars hinged respectively. Figure 10 In the middle, a coaxially extending groove is opened on the top crossbar of the U-shaped bracket 3 to place the pin at the end of the diagonal bar, forming a sliding connection so that the X-shaped bracket 6 can push the U-shaped bracket 3 in the middle position.
[0065] Reference Figures 6-8 As shown, the dust suppression spray assembly 7 includes a hinge seat 71 disposed between adjacent U-shaped supports 3. The hinge seat 71 has grooves on both sides, and a pin is installed in the groove. The upper end of the connecting rod 76 is passed through the pin. The lower end of the connecting rod 76 is hinged to the top crossbar of the U-shaped support 3. The top crossbar of the U-shaped support 3 has notches 77 on both sides, and a pin is also installed in the notches 77 for passing through the lower end of the connecting rod 76.
[0066] When several U-shaped supports 3 retract, the fan-shaped motion of the connecting rod 76 can drive the spray dust suppression component 7 to retract upward; conversely, when several U-shaped supports 3 unfold, the fan-shaped motion of the connecting rod 76 can drive the spray dust suppression component 7 to unfold downward synchronously.
[0067] like Figure 11 As shown, the hinge seat 71 and the connecting rod 76 are fitted with limit screws arranged vertically and horizontally at intervals to prevent the connecting rod 76 from being straightened and to avoid the overall structure from being difficult to close.
[0068] The spray pipe 72 is fixedly sleeved in the middle of the hinge seat 71, and the upper end of the spray pipe 72 is connected to the water injection pipe 78; multiple corrugated pipes are provided on the water injection pipe 78 at intervals to facilitate compression.
[0069] A sealing ring is fixed inside the spray pipe 72, and an extension pipe 73 is sleeved in the sealing ring. Two spray nozzles 74 are connected to both sides of the extension pipe 73.
[0070] The lower end of the spray pipe 72 is threaded to a bolt 75, which is located below the sealing ring and abuts against the extension pipe 73.
[0071] The lower end of the extension tube 73 is connected to one end of the telescopic hose 791, and the other end of the telescopic hose 791 is connected to the spray valve nozzle 792.
[0072] With this structure, the staff can use the spray nozzle 792 to discharge a portion of the water inside the spray pipe 72 to the designated spray dust suppression location through the extension pipe 73, thus forming a fixed-point spray dust suppression operation. It also makes it easy to spray a portion of the water onto the building, forming a building watering operation, thus making full use of the water source of the spray dust suppression system.
[0073] The spray pipe 72 is slidably connected to a sliding block 793. A protrusion is provided on one side of the sliding block 793, and a hanging slot 795 is provided on the protrusion. The telescopic hose 791 passes through the hanging slot 795.
[0074] The suspension mount 795 can be semi-enclosed to remove the telescopic hose 791.
[0075] A tension spring 794 is fixedly connected between the sliding block 793 and the hinge seat 71;
[0076] By pulling down the tension spring 794, the sliding block 793 is lowered to a position suitable for suspending the telescopic hose 791 on the suspension latch 795. Then, the tension spring 794 is released and reset, allowing the folded telescopic hose 791 to retract upwards. This provides a retraction protection effect, preventing the excessively long telescopic hose 791 from being positioned too low, affecting personnel movement, obstructing vision, or entangled in other construction materials during transportation.
[0077] Example 2
[0078] The specific steps of using the automatic sprinkler dust suppression device for aerial building construction machines as described in Example 1 are as follows:
[0079] S1: Install crossbeam 1 on the steel frame of the building machine;
[0080] S2: Install the remaining components based on beam 1;
[0081] S3: Water injection pipe 78 is connected to the water pump, and the water pump is connected to the water tank;
[0082] S4: Start motor 84 to rotate forward, unfold the sunshade cloth 2 and the dust suppression spray assembly 7, and start the water pump to spray water;
[0083] S5: After the spraying is completed, start motor 84 to reverse so as to retract the sunshade cloth 2 and the spraying dust suppression component 7.
[0084] This method facilitates dust suppression through spraying.
[0085] In this embodiment, in S1, the crossbeam 1 extends above the concrete.
[0086] In S3, the water tank and water pump are provided with sunshade measures so that the water pipes, water tank, and water pump are all provided with sunshade measures.
[0087] In S4, the spray nozzle 792 is closed, and the concrete is automatically watered and cured by the spray nozzle 74. Alternatively, the valve of the spray nozzle 74 is closed, the sliding block 793 is pulled down, the telescopic hose 791 is disengaged from the suspension bayonet 795, and the operator holds the spray nozzle 792 to water and cure the concrete.
[0088] This method is beneficial for watering and curing concrete.
[0089] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, achieving the same performance or purpose, should be considered within the scope of protection of the present invention.
