DETAILED DESCRIPTION

[0026] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0028] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a dust suppression device for construction engineering, including a tower body 100, a tower crane arm 200 installed on the top of the tower body 100, two rails 210 extending along the tower crane arm 200, a rail crane 300 installed on the lower side of the two rails 210, a traction mechanism 400 for driving the rail crane 300 to move, and a spray device 500 installed on the tower crane arm 200.

[0029] Reference Figure 1and Figure 2 The spray device 500 includes a plurality of spray heads 510 and a water hose 520 connected between the spray heads 510. The upper end of each spray head 510 is slidably installed between the two rails 210. The spray head 510 near one end of the tower body 100 is connected to the water supply pump 540 through a water supply pipe 530. The spray head 510 near the end of the tower boom 200 is detachably connected to the rail overhead travelling vehicle 300.

[0030] When it is necessary to spray dust through the tower crane, the rail crane 300 is connected to the spray head 510 near the end of the tower crane arm 200, and the rail crane 300 drives the spray head 510 to move toward the end of the tower crane arm 200. The spray heads 510 are separated by water hoses 520 (such as Figure 1 As shown), the high-pressure water is then delivered to each spray head 510 through the water supply pump 540, and the high-pressure water is sprayed out through each spray head 510 to form a spray, thereby achieving spray dust reduction. After the spray dust reduction is completed, the rail overhead crane 300 moves the spray head 510 near the end of the tower crane arm 200 to the side near the tower body 100, and then separates the spray head 510 from the rail overhead crane 300 (as shown). Figure 2 Therefore, when not in use, the spray device 500 of the present application is stored on the side of the tower crane arm 200 close to the tower body 100, which is convenient for the maintenance or replacement of the spray head 510. At the same time, the original rail crane 300 of the tower crane is used to drive the spray head 510 near the end to move, without the need to set up an additional traction device, thereby reducing the modification cost of the tower crane.

[0031] In a specific embodiment, referring to Figure 3 A connection seat 511 is provided at the upper end of the spray head 510 near the end of the tower crane arm 200, a driving motor 512 is provided in the connection seat 511, an output shaft of the driving motor 512 faces the side of the rail overhead crane 300 and passes through the connection seat 511, and a bar-shaped locking block 513 is installed at the output end of the driving motor 512. A slot 310 for inserting the bar-shaped locking block 513 is provided on the side of the rail overhead crane 300 close to the connection seat 511, and a card slot 320 for screwing the bar-shaped locking block 513 is provided on the side wall of the slot 310 near the bottom.

[0032] When it is necessary to connect the rail crane 300 to the spray head 510 at the end of the tower crane arm 200, first align the strip locking block 513 at the side end of the connecting seat 511 with the slot 310 at the side end of the rail crane 300, and then drive the strip locking block 513 to rotate an angle through the driving motor 512, so that the two ends of the strip locking block 513 are inserted into the slots 320 in the slot 310, thereby achieving locking between the connecting seat 511 and the rail crane 300.

[0033] Preferably, a battery 514 is also provided in the connection base 511, and the battery 514 supplies power to the drive motor 512. In addition, a photovoltaic panel is provided outside the connection base 511, and the photovoltaic panel is electrically connected to the battery 514, so that the battery 514 is charged by solar energy.

[0034] Reference Figure 1 and Figure 2 A limit block 220 is provided on the tower crane arm 200 near the tower body 100, and the limit block 220 is used to limit the travel of the connecting seat 511. Preferably, the limit block 220 and the connecting seat 511 are magnetically attracted to each other. In this embodiment, the limit block 220 is an iron block, and a magnet block 515 is provided on the connecting seat 511. The connecting seat 511 is magnetically attracted to the limit block 220 through the magnet block 515. After the connecting seat 511 is separated from the rail overhead crane 300, the limit block 220 and the connecting seat 511 are magnetically fixed together, so that the spray head 510 can be locked during normal operation of the tower crane to prevent the spray head 510 from slipping out and affecting the normal operation of the tower crane.

[0035] Reference Figure 4 , this embodiment also includes a controller 600 and a dust reduction start / stop button 700; a first proximity sensor 221 is provided on the side of the limit block 220 facing the connecting seat 511, and a second proximity sensor 516 is provided on the side of the connecting seat 511 facing the rail overhead travelling vehicle 300; the dust reduction start / stop button 700, the first proximity sensor 221 and the second proximity sensor 516 are electrically connected to the signal input end of the controller 600 respectively, and the traction mechanism 400, the water supply pump 540 and the drive motor 512 are electrically connected to the signal output end of the controller 600 respectively; the controller 600 of this embodiment is a PLC controller 600, and the PLC controller 600 communicates with the first proximity sensor 221, the second proximity sensor 516, the traction mechanism 400, the water supply pump 540 and the drive motor 512 through a wireless module.

[0036] When spray dust reduction is required, the dust reduction start and stop button 700 is pressed, and the dust reduction start and stop button 700 sends a control signal to the controller 600. The controller 600 first outputs a signal to control the traction mechanism 400 to drive the rail crane 300 to move toward the connecting seat 511. When the second proximity sensor 516 detects that the rail crane 300 is approaching, it means that the strip lock block 513 on one side of the connecting seat 511 is inserted into the slot 310 on one side of the rail crane 300. At this time, the controller 600 controls the traction mechanism 400 to stop and controls the drive motor 512 to drive the strip lock block 513 to rotate an angle, so that the two ends of the strip lock block 513 are inserted into the slots 320 in the slot 310, and then controls the rail crane 300 to move in the direction away from the limit block 220, and then the water supply pump 540 can be controlled to start and spray dust reduction is performed.

[0037] After the spray dust reduction is finished, the dust reduction start-stop button 700 is pressed again, and the dust reduction start-stop button 700 sends a control signal to the controller 600, and the controller 600 outputs a signal to control the water supply pump 540 to stop, and controls the traction mechanism 400 to drive the rail crane 300 to move toward the limit block 220. When the first proximity sensor 221 detects that the rail crane 300 is approaching, the traction mechanism 400 is controlled to stop, and then the drive motor 512 is controlled to drive the bar lock block 513 to rotate in the opposite direction by an angle, so that the two ends of the bar lock block 513 exit the card slot 320 in the slot 310, and then the rail crane 300 is controlled to move in a direction away from the connecting seat 511, so that the rail crane 300 can be separated from the connecting seat 511. Therefore, the present application can control the tower crane to switch between spray dust reduction and normal operation with one key, and the operation is very convenient.
