Description

Technical Field

[0001] This utility model relates to the field of high-altitude dust spraying technology, and in particular to a tower crane structure with a high-altitude dust spraying device. Background Technology

[0002] In the construction industry, high-altitude dust pollution has always been an environmental problem that urgently needs to be solved. As the core equipment for high-rise building construction, the high-altitude dust control technology of tower cranes is particularly crucial.

[0003] When existing high-altitude dust suppression spraying devices are used on tower cranes, the nozzles are often clogged with scale, dust and other debris after long-term use, which leads to a significant decrease in the efficiency of water spraying and dust suppression. In addition, traditional cleaning methods require manual shutdown, which is not only inefficient but also poses safety hazards. Furthermore, cleaning the nozzles often requires stopping water spraying, resulting in gaps in dust control and making it impossible to achieve continuous dust suppression.

[0004] In addition, the high-pressure water pipes of the existing equipment are prone to breakage due to folding and pulling during the movement of the spraying equipment, which affects the stability of the equipment. Utility Model Content

[0005] In view of the problems of easy clogging of nozzles, safety hazards during shutdown cleaning, and easy breakage of high-pressure water pipes during movement in the above-mentioned or existing technologies, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a first cleaning mechanism, which includes a tower crane, a T-shaped sliding rod fixedly provided on one side of the tower crane, a movable part provided on one side of the T-shaped sliding rod, the movable part including a movable seat, a first cleaning assembly provided on one side of the movable part, the first cleaning assembly including a perforated plate used as a first nozzle, and a pin for clogging cleaning provided on one side of the perforated plate;

[0007] The second water spraying mechanism includes a second water spraying assembly disposed on one side of a perforated plate. The second water spraying assembly includes a plurality of arc-shaped plates that can be unfolded to one side. A first connecting rod is rotatably disposed on one side of the plurality of arc-shaped plates. A second connecting rod is rotatably connected to one side of the plurality of first connecting rods. A circular mesh serving as a second nozzle is fixed on one side of the plurality of second connecting rods.

[0008] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of the present invention, the first cleaning component further includes a first protective shell fixedly disposed through one side of the movable seat, and a second protective shell for fixing a perforated plate is fixedly disposed on one side of the first protective shell.

[0009] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of this utility model, the moving part further includes several asynchronous motors fixed on one side of the moving base, and rollers that abut against the T-shaped sliding rod are fixed on one side of the output end of the several asynchronous motors.

[0010] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of this utility model, wherein: an electric push rod for pushing the pin to perform reciprocating cleaning is fixed in the middle of one side of the inner cavity of the moving seat.

[0011] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of this utility model, wherein: a circular ring is movably provided through one side of the arc-shaped plate, and a back plate fixedly connected to the first protective shell is provided on one side of the circular ring.

[0012] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of this utility model, wherein: a plurality of telescopic cylinders for cleaning are provided on one side of the circular mesh, and a compression spring for resetting is fixed on one side of the plurality of telescopic cylinders, and the compression spring is movably arranged in a fixed crossbar fixedly connected to the first protective shell.

[0013] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of this utility model, wherein: a plurality of limiting slide plates are slidably arranged on one side of the T-shaped slide bar, and a fixed ring is connected to one side of the plurality of limiting slide plates.

[0014] As a preferred embodiment of the tower crane structure with a high-altitude dust spraying device of this utility model, a high-pressure water pipe is fixedly installed in the inner cavity of the fixed ring, and a folding rod is provided on one side of the high-pressure water pipe to be connected to the limiting slide plate and to prevent the high-pressure water pipe from being torn off.

[0015] The beneficial effects of the tower crane structure with a high-altitude dust spraying device of this utility model:

[0016] 1. Utilizing an electric actuator to drive the reciprocating motion of the pin, the nozzles of the perforated plate are automatically cleaned. This solves the safety hazards and inefficiencies of traditional manual cleaning, which requires machine shutdown. It also prevents water spraying efficiency reduction caused by scale and dust blockage, ensuring continuous and effective nozzle operation. The protective structure of the first and second protective shells also prevents water leakage during cleaning, ensuring the reliability of the cleaning operation.

[0017] 2. Through the linkage structure consisting of an arc-shaped plate, a first connecting rod, a second connecting rod, and a circular mesh, when the needle cleans the perforated plate, the circular mesh moves with the needle and pushes the arc-shaped plate to unfold, forming a backup spraying channel. At this time, water flows continuously through the holes of the circular mesh, solving the problem of water spraying pausing during traditional cleaning, ensuring uninterrupted dust suppression and improving the continuity of high-altitude dust control.

[0018] 3. The limiting slide plate on the T-shaped sliding rod cooperates with the folding rod to fix the ring. When the moving seat moves the high-pressure water pipe, the folding rod can automatically fold or unfold as the limiting slide plate approaches or separates, preventing the high-pressure water pipe from breaking due to gravity pulling or movement folding. At the same time, it avoids the pipeline interfering with the operation of the tower crane trolley, ensuring the safety and stability of the equipment during the movement process.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a tower crane structure with a high-altitude dust spraying device, which can achieve the effect of automatically cleaning the nozzle blockage. It includes a first cleaning mechanism, which includes a tower crane 1. The lower end of the upper crossbeam inside the boom of the tower crane 1 is connected via a... Figure 2 The fixed rod shown is fixedly equipped with a T-shaped sliding rod 2, thereby fixing the entire device. A movable part is slidably provided at the lower end of the T-shaped sliding rod 2. The movable part includes an upper part that is concave at the slidable connection point with the T-shaped sliding rod 2, and a hollow movable seat 3 at the lower end. Figure 3 As shown, the moving part also includes several asynchronous motors 4 fixedly installed on the lower exterior of the moving seat 3. The several asynchronous motors 4 are symmetrical to each other and have the same structure. In this device, two are preferred. The output ends of the two asynchronous motors 4 are fixedly connected to a rotating shaft through a coupling. The rotating shaft passes through the lower cavity of the entire moving seat 3. A roller 5 is fixedly installed at the end of the rotating shaft that passes through the moving seat 3. The outer ring surface of the roller 5 abuts against the lower surface of the T-shaped slide rod 2. The asynchronous motor 4 drives the roller 5 to rotate, thereby driving the moving seat 3 to move on the T-shaped slide rod 2.

[0030] An electric actuator 6 is fixedly installed in the middle of the hollow inner wall at the lower end of the movable seat 3, and a pin 7 is fixedly installed at the telescopic end of the electric actuator 6. A first protective shell 8 for protection is movably installed through the end of the pin 7 away from the electric actuator 6. A sealing ring (not shown in the figure) is installed at the penetration position of the pin 7 and the first protective shell 8 to seal the connection. Thus, when the pin 7 moves inside the first protective shell 8, the water inside the first protective shell 8 will not flow out. A second protective shell 9 is fixedly installed at the end of the first protective shell 8 away from the electric actuator 6. A perforated plate 10 for the first nozzle is fixedly installed in the inner cavity of the end of the second protective shell 9 away from the first protective shell 8. The perforated plate 10 and the pin 7 are located on the same axis, and the pin 7 can be inserted into the hole of the perforated plate 10 to clean the hole of the perforated plate 10 used for water spraying, preventing scale buildup and blockage of the water spraying hole of the perforated plate 10 after long-term use.

[0031] Several limiting slide plates 20 are slidably arranged in a groove on one side of the T-shaped slide bar 2, and the limiting slide plates 20 and the T-shaped slide bar 2 mutually limit each other. The lower ends of the limiting slide plates 20 are rotatably connected to a fixed ring 22 on one side surface of the T-shaped slide bar 2, and a high-pressure water pipe 23 is fixedly installed in the middle of the inner cavity of the fixed ring 22. The fixed rings 22 have the same structure and are spaced apart. A folding rod 21 is rotatably arranged on the side of the high-pressure water pipe 23 that is fixed to the fixed ring 22, and the folding rod 21 is connected to the limiting slide plate. The two limit plates 20 are connected to each other by rotation. At the same time, the middle of the folding rod 21 is also equipped with a fixed ring 22. When two adjacent limit plates 20 are close to each other, the folding rod 21 can fold the high-pressure water pipe 23, thereby preventing the high-pressure water pipe 23 from interfering with the movement of the trolley on the boom of the tower crane 1 due to its long length when it falls due to gravity, thus preventing the occurrence of safety hazards. At the same time, when two adjacent limit plates 20 are far apart, the interaction between the folding rod 21 and the fixed ring 22 can prevent the high-pressure water pipe 23 from being torn off.

[0032] Specifically, a circular fixing plate is provided at the fixed connection between the pin 7 and the electric push rod 6, and the telescopic end of the electric push rod 6 is fixed to the middle of the circular fixing plate through a fixing member, so that the pin 7 can move horizontally as a whole, and can be accurately inserted into the sprinkler hole of the perforated plate 10, thereby preventing the pin 7 from shifting and failing to clean the perforated plate 10.

[0033] Furthermore, the length of the folding rod 21 is less than the distance from the upper crossbeam of the tower crane 1 boom to the trolley, so as to prevent the high-pressure water pipe 23 from interfering with the movement of the trolley during the reciprocating movement of the entire device.

[0034] The sensor is fixed at the telescopic end of the electric actuator 6 by a fastener. The sensor can be a Honeywell PX2 series pressure sensor. The asynchronous motor 4 and the electric actuator 6 can be connected to the PLC controller.

[0035] It should be noted that the asynchronous motor 4 and the electric actuator 6 are existing technologies, and their structural principles will not be elaborated here. The asynchronous motor 4 can be the Y180L-6 pole 15KW6P model, and the electric actuator 6 can be the LX835 electric actuator 3500N model.

[0036] In use, the output of the asynchronous motor 4 is controlled by the PLC to rotate, which in turn drives the roller 5 to rotate synchronously, allowing the roller 5 to move on the T-shaped slide bar 2. The roller 5 then drives the moving seat 3 to move synchronously. When the moving seat 3 moves on the T-shaped slide bar 2, it can pull the fixed ring 22 to move through the high-pressure water pipe 23. When the fixed ring 22 moves, it will cause the folding rod 21 to unfold or flip, which in turn pushes several limiting slide plates 20 to move closer or separate, thereby protecting the high-pressure water pipe 23 and preventing it from being broken due to the long distance to be moved and the influence of the gravity of the internal water flow.

[0037] As the movable seat 3 moves, the extension and retraction end of the electric push rod 6 is extended and retracted by the PLC, thereby pushing the pin 7 to be inserted and removed in the first protective shell 8. This allows the end of the pin 7 to be inserted and removed back and forth in the water spray holes of the perforated plate 10 for cleaning, thereby preventing scale or other blockages in the water spray holes of the perforated plate 10 after long-term use from clogging the perforated plate 10 and affecting the effect of water spraying to reduce dust.

[0038] Example 2, refer to Figures 5-7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a second water spraying mechanism for a tower crane structure with a high-altitude dust spraying device. This solves the problem of water spraying pausing when the needle 7 cleans the holes of the perforated plate 10. The second water spraying mechanism includes a second water spraying component disposed on one side of the perforated plate 10. The second water spraying component includes a back plate 15 fixedly disposed on the side wall of the first protective shell 8 located on the side of the second protective shell 9. The inner diameter of the back plate 15 is the same as the inner diameter of the first protective shell 8. A ring 14 is fixedly disposed on the side of the back plate 15 away from the first protective shell 8. The ring 14 movably passes through one end of the arc plate 11, thereby making the arc plate 11 and the ring 14 rotatably connected, so that the arc plate 11 can be flipped.

[0039] A first connecting rod 12 is rotatably mounted on the inner arc surface of the arc plate 11 away from the ring 14. A second connecting rod 13 is rotatably connected to the first connecting rod 12 on the side of the ring 14. The end of the second connecting rod 13 away from the first connecting rod 12 is fixedly connected to the circular strainer 16. The inner ring surface of the circular strainer 16 is fixedly connected to the pin 7. Thus, when the pin 7 moves, it can drive the circular strainer 16 to move. In turn, the circular strainer 16 drives the second connecting rod 13 to move, causing the second connecting rod 13 to push the first connecting rod 12. Under the action of the ring 14 on the arc plate 11, the first connecting rod 12 will push the arc plate 11 to flip outward. The circular strainer 16 moves with the pin 7 to the opening of the second protective shell 9 on the side of the first protective shell 8, so that the water flows outward through the holes provided on the upper part of the circular strainer 16.

[0040] A plurality of telescopic cylinders 18 are provided on the outer ring surface of the circular mesh 16. The telescopic cylinders 18 are aligned with the holes provided on the circular mesh 16 and are inserted into each other. The telescopic cylinders 18 clean the holes on the circular mesh 16 to prevent the holes of the circular mesh 16 from becoming blocked like the holes of the perforated plate 10. The side of the telescopic cylinders 18 away from the circular mesh 16 is fixedly connected to one end of a compression spring 19 for resetting. The other end of the compression spring 19 is fixedly connected to the bottom surface of the retraction groove opened on the fixed crossbar 17. As the circular mesh 16 moves, it squeezes the telescopic cylinders 18, and the telescopic cylinders 18 squeeze the compression spring 19, so that the telescopic cylinders 18 retract into the retraction groove of the fixed crossbar 17. The fixed crossbar 17 is fixedly set on the inner surface of the first protective shell 8.

[0041] Specifically, the rotation angle of the arc plate 11 is between 60° and 90°, so that the water spray angle is more uniform. The arc plate 11 is located between the first protective shell 8 and the second protective shell 9, and is located at the end closer to the perforated plate 10, so that it can spray further and the spraying effect is better.

[0042] Furthermore, the length of the circular mesh 16 is greater than that of the arc plate 11, and when the circular mesh 16 moves toward the second protective shell 9, it can not only push the arc plate 11 to flip, but also block the opening after the arc plate 11 flips, preventing water from flowing out directly and causing water column spraying, reducing the area covered by the spray, and thus affecting the dust suppression effect.

[0043] When in use, the movement of the pin 7 causes the circular strainer 16 to move synchronously. The circular strainer 16 then moves the second connecting rod 13, which in turn pushes the first connecting rod 12. Under the limiting effect of the ring 14 and the back plate 15 on the arc plate 11, the first connecting rod 12 pushes the arc plate 11 outward, causing the arc plate 11 to rotate outward by 60°-90°. When the arc plate 11 is rotated into place, the circular strainer 16 and the second protective shell 9 come into contact. At this time, the water can be sprayed outward through the holes on the circular strainer 16 in a splashing manner, thus making the spray coverage area wider.

[0044] When the circular mesh 16 moves toward the second protective shell 9, it will squeeze the telescopic cylinder 18, causing the telescopic cylinder 18 to retract into the fixed crossbar 17. When the circular mesh 16 returns, the telescopic cylinder 18 is pushed out by the compression spring 19 and then re-inserted into the hole of the circular mesh 16 as in its original state. At the same time, the hole of the circular mesh 16 is cleaned to prevent the hole of the circular mesh 16 from becoming blocked.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
