Description

Technical Field

[0001] The present application relates to the technical field of construction site construction, and specifically to an automatic sprinkling, dust removal and temperature reduction device for a gantry crane. Background Technique

[0002] Adverse factors such as dust, sundries and high temperature usually exist in the construction site environment. Automatic sprinkling and dust removal devices can effectively reduce the impact of these factors on workers and equipment, thereby improving overall safety. Sprinkling and temperature reduction can continuously improve the construction site environment without affecting the operation progress, enabling workers to work in a more comfortable state, thereby improving work efficiency.

[0003] After retrieval, the publication number is CN211635748U, which discloses a dust reduction device for road construction, including a load-bearing plate. At both ends of the load-bearing plate along its length direction, slope plates are respectively hinged. Along the length direction of the top of the load-bearing plate, a gantry frame is fixedly connected. Between the free ends of the slope plates and the gantry frame, a hydraulic telescopic rod is provided. Both ends of the hydraulic telescopic rod are respectively hinged to the free end of the slope plate and the gantry frame. Multiple gantry frame type water pipes are fixedly connected to the top of the load-bearing plate. The top of the water pipes is fixedly connected to the gantry frame. Multiple nozzles are evenly communicated with the inner surface of the water pipes. A water pump is installed on one side of the load-bearing plate. The water inlet of the water pump is communicated with a water inlet pipe, and the water outlet is communicated with each water pipe through a main delivery pipe. This device has the advantages of being easy to transport and move, and can effectively carry out dust reduction treatment on the dust raised by vehicles.

[0004] However, for the existing sprinkling devices of gantry cranes, although they can achieve sprinkling, dust removal and temperature reduction in the gantry area, generally, the method adopted is to install multiple nozzles on a water pipe to atomize liquid water to achieve the purpose of temperature reduction and dust removal. Such a method will result in a relatively narrow coverage area of the atomized water mist of the nozzles, and can only carry out temperature reduction and dust removal in the area near the gantry. When the coverage area can be increased for temperature reduction and dust removal, the achieved temperature reduction and dust removal effects are better.

[0005] It should be noted that the above information disclosed in this background technique section is only used to understand the background technique of the concept of the present application, and therefore, it may include information that does not constitute the prior art.

[0033] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0034] Please refer to Figures 1-4 , the embodiments provided by the present utility model:

[0035] An automatic sprinkling, dust removal and cooling device for a gantry crane, comprising a gantry frame body 1. The gantry frame body 1 includes a support arm 11 and a cross beam 12. Both sides of the bottom surface of the cross beam 12 are fixedly installed with the top ends of the support arms 11 through screws. A reciprocating motion assembly 2 is fixedly installed at the center of the bottom surface of the cross beam 12. The bottom end of the reciprocating motion assembly 2 is fixedly installed with a spray assembly 4 for sprinkling, dust removal and cooling. The reciprocating motion assembly 2 drives the spray assembly 4 to swing back and forth below the cross beam 12 under the drive of a drive assembly 3. The main principle is that the drive assembly 3 drives the reciprocating motion so that the spray assembly 4 can swing back and forth at a certain angle, thereby increasing the coverage area of sprinkling, dust removal and cooling to achieve a better dust removal and cooling effect.

[0036] Specifically, the reciprocating motion assembly 2 includes a bearing seat 21, a rotating rod 22, a gear 23, a rack 24, a pin 25 and a rocker 26. The bearing seat 21 is fixedly installed at the center of the bottom surface of the cross beam 12 through screws. The top end of the rotating rod 22 is fixedly installed with the inner ring of the bearing seat 21. The side wall of the rotating rod 22 is key-connected to the inside of the gear 23. The bottom end of the rotating rod 22 is fixedly installed with the spray assembly 4. The side wall of the gear 23 is meshed with the rack 24. Rotating holes are respectively opened at both ends of the rocker 26. The side wall of the pin 25 is rotatably connected in the rotating holes. There are two pins 25, and one of the pins 25 is fixedly installed with the end of the rack 24;

[0037] The driving assembly 3 includes a disc 31, a driving motor 32 and a first mounting bracket 33. The first mounting bracket 33 is fixedly mounted on the bottom surface of the beam 12. The driving motor 32 is fixedly mounted on the inner bottom surface of the first supporting bracket by screws. The output shaft of the driving motor 32 is connected to the center key of the disc 31. The eccentric portion of the bottom surface of the disc 31 is fixedly mounted to another pin 25.

[0038] The principle is: the driving motor 32 drives the disc 31 to rotate, so that the rocker 26 below the disc 31 can move in a circle on the disc 31 through the pin 25 as the disc 31 rotates, so that the other end of the rocker 26 rotates on the pin 25 on the rack 24, and also pulls the rack 24 to reciprocate. Since the rack 24 and the gear 23 are meshingly connected, the gear 23 can rotate forward or reverse during the reciprocating motion of the rack 24, and drive the rotating rod 22 to rotate forward and reverse, and then the spray assembly 4 swings back and forth with the forward and reverse rotation of the rotating rod 22, thereby increasing the coverage area of the spray.

[0039] The spray assembly 4 includes a spray pipe 41 and a spray head 42. A plurality of spray heads 42 are installed on the side wall and the bottom surface of the spray pipe 41. The plurality of spray heads 42 are gradually sparsely arranged from the center of the spray pipe 41 to both ends. Through the arrangement of the spray heads 42, when water is supplied in the middle of the spray pipe 41, the water pressure of each spray head 42 can be ensured to be consistent, so as to prevent the spray heads 42 at both ends of the spray pipe 41 from failing to atomize liquid water due to insufficient water pressure.

[0040] It is worth noting that the nozzle 41 is in the shape of a hexagonal prism, and multiple nozzles 42 are respectively installed on the three surfaces of the bottom of the hexagonal prism-shaped nozzle 41. By designing the nozzle 41 in the shape of a hexagonal prism, on the one hand, it is convenient to install the nozzle 42 and the rotating rod 22, and on the other hand, the angle of the nozzle 42 can be changed, thereby further improving the coverage area of dust reduction and cooling to a certain extent.

[0041] A joint is installed on the top surface of the nozzle 41, and a water supply assembly 5 is butt-mounted on the joint. The water supply assembly 5 includes a water inlet pipe 51, a clamp 52 and a telescopic spring water pipe 53. One end of the telescopic spring water pipe 53 is butt-mounted with the joint, and the other end of the telescopic spring water pipe 53 is butt-mounted with the water inlet end of the water inlet pipe 51. The water inlet pipe 51 is installed on the bottom surface of the beam 12 through a plurality of clamps 52.

[0042] In order to supply water during the rotation of the nozzle 41, a telescopic spring water pipe 53 assembly is used, so that when the nozzle 41 swings under the drive of the rotating rod 22, the telescopic spring water pipe 53 can be stretched and reset to supply water to the nozzle 41 in the swinging state.

[0043] To ensure that the rack 24 is always meshed and connected with the gear 23, a limiting component 6 is installed on the side wall of the rack 24. The limiting component 6 includes a second mounting bracket 61, a limiting plate 62, a limiting groove 63 and a limiting block 64. The second mounting bracket 61 is fixedly installed on the bottom surface of the cross beam 12. Two limiting plates 62 are fixedly connected to the bottom side walls of the second mounting bracket 61 respectively. Limiting grooves 63 are respectively formed on the opposite surfaces of the two limiting plates 62. Limiting blocks 64 are fixedly connected to the top surface and the bottom surface of the rack 24 respectively. The limiting blocks 64 are respectively slidably connected in the limiting grooves 63. The displacement direction of the rack 24 is guided through the limiting grooves 63 to ensure that the moving direction of the rack 24 remains unchanged and it is always meshed with the gear 23, thus ensuring the forward and reverse driving of the rotating rod 22.

[0044] In order to be able to detect the size of dust in the air and make the driving motor 32 work when the dust is large, an ultrasonic particle sensor 7 for detecting dust in the air is installed on the side wall of the support arm 11. The size of dust near the gantry is detected by the ultrasonic particle sensor 7. Then, in cooperation with the controller receiving the electrical signal detected by the ultrasonic particle sensor 7, according to the set threshold, the power supply and power off of the driving motor 32 and the water supply of the water pump to the water inlet pipe 51 are controlled, so as to achieve the purpose of dust reduction and temperature reduction.

[0045] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
