Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a high-altitude tower crane spray dust removal construction equipment for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project, encompassing the construction process of various buildings. The site where construction work takes place is called the construction site or work area. During construction, a large area of ​​dust is generated on the work site. This dust not only affects the physical safety of workers but also pollutes the atmospheric environment. Therefore, sprinkler systems are used to spray water to suppress dust on the work site. Due to the large area of ​​construction sites, ordinary sprinkler systems cannot effectively control the dust. Therefore, sprinkler systems are installed on tower cranes in high altitudes to spray water from above to suppress dust on the work site, thereby improving the dust suppression effect.

[0003] Chinese patent discloses a dust suppression spraying system based on a high-altitude tower crane (CN212942061U), comprising a support mechanism including a base plate, a support frame, and a fixing frame. The support frame is mounted on the upper part of the base plate, and the fixing frame is mounted on top of the support frame. A spraying mechanism is located on one side of the support mechanism. The spraying mechanism includes a control center, an extension frame, a mounting box, a counterweight, a water tank, a connecting pipe, a water pump, a spray pipe, a pipe clamp, a connecting pipe, spray blocks, and a water injection pipe. The mounting box is located on one side of the control center. This invention uses a spraying mechanism with two water pumps to provide water to the spray blocks, ensuring a sufficient water supply. Furthermore, the action of multiple spray blocks significantly increases the dust suppression area. The spraying can be adjusted via the control center to rotate and spray. The spray device mentioned in the comparative document cannot be adjusted in area according to the dust coverage area, and cannot quickly remove dust over a large area. If there is not much dust, using a spray device of the same area will easily lead to waste of water resources. Furthermore, the comparative document does not filter the water. If unfiltered water is used for a long time, the spray device will become clogged, thereby affecting the dust removal effect and rate. Therefore, a high-altitude tower crane spray dust removal construction equipment for building construction is provided. Summary of the Invention

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In this invention, by providing an expansion box, when it is necessary to increase the spray volume or spray area, the output power of the water pump is adjusted, and then the water flow will flow out from the pressure relief pipe next to the connecting sleeve. At this time, the water flow will impact the sealing block inside the pressure relief pipe, causing the sealing block to move downward along the inner wall of the pressure relief pipe. When the sealing block moves out of the pressure relief pipe, and the expansion box is no longer blocked by the sealing block, the telescopic spring will pop the expansion box out of the spray box, thereby increasing the spray area of ​​the spray box. The spray area can be automatically adjusted according to the water volume, thereby achieving the purpose of saving water resources and maintaining stable dust removal efficiency for a long time.

[0027] 2. In this invention, by setting a rotating rod and a spiral blade, the water flow can impact one side of the spiral blade, thereby causing the spiral blade to drive the spray box to rotate through the rotating rod. At the same time, the water flow will flow into the spray box through the connecting sleeve, and then the water will be sprayed out onto the construction site through the spray nozzle on the lower surface of the spray box. Spraying while rotating further expands the spraying area of ​​the device and improves the dust suppression effect.

[0028] 3. In this invention, a water storage component is installed. Water from the ground is transported to the water tank through an inlet pipe. The water is first filtered by a filter plate in the tank, and impurities in the water flow remain on the upper surface of the filter plate before flowing to the bottom for storage. When the water level in the tank reaches a certain point, a water level monitor is triggered. The monitor then transmits a signal to the motor, causing the motor to drive the worm gear to rotate. Since the worm gear is meshed with a worm wheel, it drives a reciprocating screw to rotate. The reciprocating screw, through its threads, causes a sliding plate to move back and forth within the limit of the sliding rod, thereby causing the scraper to move back and forth on the upper surface of the filter plate. When the scraper moves to a certain position, it will push against the fixed rod. At this time, the fixed rod will drive the sealing column to move outward of the water tank. The scraper will then scrape impurities through the discharge chute into the collection box. When the scraper loses pressure on the fixed rod, the tension spring will drive the sealing column back, thereby blocking the discharge chute. Then, the water pump will draw water from the water tank through the water outlet pipe. The water in the water outlet pipe will flow through the T-joint to the two branch pipes at both ends. The water will pass through the elbow, where it will be blocked by the baffle to prevent impurities in the water from clogging the spray nozzles below the spray box, thus ensuring the stability of the device. At the same time, it can automatically clean impurities, realizing the automation of the device. Attached Figure Description

[0041] Please see Figure 1-7 The present invention provides a technical solution: a high-altitude tower crane spray dust removal construction equipment for building construction, including a tower arm 1, a first fixing sleeve 4 and a second fixing sleeve 5 respectively fixedly installed on the upper surface of the tower arm 1, a diversion pipe 7 fixedly installed on the upper surface of the tower arm 1 through the second fixing sleeve 5, an elbow 8 fixedly installed at one end of the diversion pipe 7, a spray assembly 3 provided at one end of the elbow 8, and a water storage assembly 9 provided on the outer surface of the tower arm 1;

[0042] The spray assembly 3 includes a spray box 31, the lower surface of which is provided with a plurality of spray nozzles. A connecting sleeve 32 is fixedly installed on the upper surface of the spray box 31. A limiting groove is provided on the inner wall of the connecting sleeve 32. A limiting ring 10 is fixedly installed on the outer surface of the elbow 8. One end of the elbow 8 is rotatably connected to the connecting sleeve 32 through the limiting ring 10. A rotating rod 33 is rotatably installed on the inner wall of the spray box 31. One end of the rotating rod 33 extends into the interior of the elbow 8 and is rotatably connected to the inner wall of the elbow 8. A spiral blade 34 is fixedly installed on the outer surface of the rotating rod 33. A stop block 11 is fixedly installed on the inner wall of the elbow 8.

[0043] The specific implementation is as follows: the water flow can impact one side of the spiral blade 34, thereby causing the spiral blade 34 to drive the spray box 31 to rotate through the rotating rod 33. At the same time, the water flow will flow into the spray box 31 through the connecting sleeve 32, and then the water will be sprayed out onto the construction site through the spray nozzle on the lower surface of the spray box 31.

[0044] A fixing block 35 is fixedly installed on the inner wall of the bottom surface of the spray box 31. A telescopic spring 36 is fixedly installed on the side wall of the fixing block 35. An expansion box 37 is fixedly installed at one end of the telescopic spring 36. Several spray nozzles are provided on the upper surface, lower surface and side wall of the expansion box 37. Two opening slots are provided on the side wall of the spray box 31. The opening slots are the same size as the expansion box 37. Two pressure relief pipes 38 are fixedly installed on the outer surface of the connecting sleeve 32. One end of the pressure relief pipe 38 extends into the interior of the connecting sleeve 32 and the other end extends into the interior of the spray box 31. A compression spring 39 is fixedly installed on the upper surface of the expansion box 37. A sealing block 310 is fixedly installed at one end of the compression spring 39. The sealing block 310 and one end of the compression spring 39 extend into the interior of the pressure relief pipe 38. The sealing block 310 is tightly fitted to the inner wall of the pressure relief pipe 38.

[0045] The specific implementation is as follows: When it is necessary to increase the spray volume or spray area, the output power of the water pump 93 is adjusted, and then the water flow will flow out from the pressure relief pipe 38 next to the connecting sleeve 32. At this time, the water flow will impact the sealing block 310 inside the pressure relief pipe 38, so that the sealing block 310 moves down along the inner wall of the pressure relief pipe 38. When the sealing block 310 moves out of the pressure relief pipe 38, and the expansion box 37 is no longer blocked by the sealing block 310, the telescopic spring 36 will pop the expansion box 37 out of the spray box 31, thereby increasing the spray area of ​​the spray box 31.

[0046] The water storage assembly 9 includes a water tank 91. The outer surface of the water tank 91 is fixedly connected to the side wall of the tower arm 1. A water pump 93 is fixedly installed on the inner wall of the bottom surface of the water tank 91. A water outlet pipe 2 is fixedly installed at the output end of the water pump 93. One end of the water outlet pipe 2 extends to the outer surface of the upper surface of the water tank 91. The outer surface of the water outlet pipe 2 is fixedly connected to the outer surface of the tower arm 1 through several first fixing sleeves 4. A water inlet pipe 92 is installed on the upper surface of the water tank 91. A filter plate 95 is fixedly installed on the inner wall of the water tank 91. A worm gear 96 is rotatably installed on the upper surface of the filter plate 95. One end of the worm gear 96 extends to the outer surface of the upper surface of the water tank 91. A motor 94 is fixedly installed on the upper surface of the water tank 91. The output end of the motor 94 is fixedly connected to one end of the worm gear 96. A reciprocating screw 98 is rotatably mounted, and a worm gear 97 is fixedly mounted on the outer surface of the reciprocating screw 98. The worm 96 is meshed with the worm gear 97. A slide rod 99 is fixedly mounted on the inner wall of the other side of the water tank 91. A slide plate 911 is slidably mounted on the outer surface of the slide rod 99. The other end of the slide plate 911 is threadedly connected to the outer surface of the reciprocating screw 98. A scraper 910 is fixedly mounted on the lower surface of the slide plate 911. The lower surface of the scraper 910 is in contact with the upper surface of the filter plate 95. A water level monitor is fixedly mounted on the lower surface of the filter plate 95. The water level monitor is electrically connected to the input end of the motor 94.

[0047] The specific implementation is as follows: Water from the ground is transported to the water tank 91 through the water inlet pipe 92. When the water is in the water tank 91, it will first pass through the filter plate 95 for filtration. Impurities in the water flow will remain on the upper surface of the filter plate 95 and then flow to the bottom of the filter plate 95 for storage. When the water in the water tank 91 reaches a certain level, it will trigger the water level monitor. At this time, the water level monitor will transmit a signal to the motor 94, causing the motor 94 to drive the worm 96 to rotate. Since the worm 96 is meshed with the worm wheel 97, it will drive the reciprocating screw 98 to rotate through the worm wheel 97. At this time, the reciprocating screw 98 will cause the sliding plate 911 to move back and forth under the limit of the sliding rod 99 through the thread on its surface, thereby driving the scraper 910 to move back and forth on the upper surface of the filter plate 95.

[0048] A discharge trough 912 is provided on the side wall of the water tank 91. A sealing column 914 is slidably installed on the inner wall of the discharge trough 912. A fixing rod 915 and a tension spring 916 are fixedly installed on the side wall of the sealing column 914. One end of the fixing rod 915 and the tension spring 916 extends into the interior of the water tank 91. A fixing plate 917 is fixedly installed on the outer surface of the fixing rod 915. The side wall of the fixing plate 917 is fixedly connected to the inner wall of the water tank 91. One end of the tension spring 916 is fixedly connected to the side wall of the fixing plate 917. The fixing rod 915 passes through the tension spring 916. A collection box 913 is fixedly installed on the outer surface of the water tank 91. A three-way connector 6 is fixedly installed on the other end of the diversion pipe 7. Another diversion pipe 7 is fixedly installed on one end of the three-way connector 6. The other end of the three-way connector 6 is fixedly connected to the upper surface of the water outlet pipe 2.

[0049] The specific implementation is as follows: When the scraper 910 moves to a certain position, it will push against the fixed rod 915. At this time, the fixed rod 915 will drive the sealing column 914 to move to the outside of the water tank 91. At this time, the scraper 910 will scrape the impurities into the collection box 913 through the discharge chute 912. When the scraper 910 loses pressure on the fixed rod 915, the tension spring 916 will drive the sealing column 914 to move back, thereby blocking the discharge chute 912. Then, the water pump 93 will draw the water in the water tank 91 out through the water outlet pipe 2. The water in the water outlet pipe 2 will flow into the two-way pipes 7 at both ends through the three-way connector 6. At this time, the water will pass through the elbow 8. When the water passes through the elbow 8, it will be blocked by the stop block 11.

[0050] Working principle: Water from the ground is transported to the water tank 91 through the inlet pipe 92. The water first passes through the filter plate 95 in the inlet tank 91 for filtration. Impurities in the water flow remain on the upper surface of the filter plate 95 before flowing to the bottom for storage. When the water level in the tank 91 reaches a certain level, it triggers the water level monitor. The monitor then transmits a signal to the motor 94, causing the motor 94 to drive the worm gear 96 to rotate. Engaging with the worm gear 97, the worm gear 97 drives the reciprocating screw 98 to rotate. The reciprocating screw 98, through its surface threads, causes the sliding plate 911 to move back and forth within the limit of the sliding rod 99. This, in turn, causes the scraper 910 to move back and forth on the upper surface of the filter plate 95. When the scraper 910 reaches a certain position, it will push against the fixing rod 915. At this point, the fixing rod 915 will cause the sealing column 914 to move outwards from the water tank 91. The scraper 910 will then remove impurities. The material is scraped into the collection box 913 through the discharge chute 912. When the scraper 910 loses pressure on the fixing rod 915, the tension spring 916 will drive the sealing column 914 to move back, thereby blocking the discharge chute 912. Then, the water in the water tank 91 is pumped out through the water outlet pipe 2 by the water pump 93. The water in the water outlet pipe 2 will flow into the two branch pipes 7 at both ends through the three-way connector 6. At this time, the water will pass through the elbow 8. When the water passes through the elbow 8, it will be blocked by the stop block 11. This allows the water flow to impact one side of the spiral blade 34, causing the spiral blade 34 to rotate the spray box 31 via the rotating rod 33. Simultaneously, the water flows through the connecting sleeve 32 into the spray box 31, and then sprays the water onto the construction site through the spray nozzles on the lower surface of the spray box 31. When it is necessary to increase the spray volume or spray area, the output power of the water pump 93 is adjusted, and the water flows out from the pressure relief pipe 38 next to the connecting sleeve 32. At this time, the water flow impacts the sealing block 310 inside the pressure relief pipe 38, causing the sealing block 310 to move downward along the inner wall of the pressure relief pipe 38. When the sealing block 310 moves out of the pressure relief pipe 38, and the expansion box 37 is no longer blocked by the sealing block 310, the telescopic spring 36 will pop the expansion box 37 out of the spray box 31, thereby increasing the spray area of ​​the spray box 31.
