Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a tower crane device for construction engineering. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also called "tower crane". It is connected section by section to lift the raw materials for construction such as steel bars, wooden slats, concrete, steel pipes, etc. Tower crane is an indispensable equipment on construction sites. The function of the tower crane tip is to bear the upper load transmitted by the arm rope and the balance arm rope, and directly transmit it to the tower structure through the turntable through the structural components such as the rotating tower, turntable, and bearing. The self-elevating tower top has truncated cone column type, forward or backward truncated cone column type, herringbone type and diagonal brace type.

[0003] Tower cranes are often used in the process of construction. Because there is a lot of dust in some construction sites, which affects the construction environment, a sprinkler system is often installed on the tower crane. Since the tower crane sprinkler system is installed at a high height and works outdoors for a long time, when the sprinkler head is damaged, the sprinkler head that is farther away is difficult for the staff to repair, which brings inconvenience to the staff's maintenance operations.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 As shown, a tower crane device for construction engineering includes a tower crane body 1 and a boom 2. The front and rear sides of both sides of the boom 2 are fixedly connected with connecting plates 3, and a screw 4 is rotatably connected between the two connecting plates 3. A motor 5 is fixed to the right side of the right connecting plate 3. The output shaft of the motor 5 is fixed to one end of the screw 4. The surface of the screw 4 is threadedly connected with a screw sleeve 6. The surface of the screw 4 is movably connected with a plurality of movable blocks 9. The front and rear sides of the screw sleeve 6 are hinged with a first support plate 7. The other end of the first support plate 7 is movably connected with a fixed pipe 11 inside. The bottoms of the fixed pipes 11 at both ends are connected with nozzles 10. The surface of the fixed pipe 11 is movably connected with a second support Rod 8, and one end of the second support rod 8 is located above one end of the first support plate 7, and the other end of the second support rod 8 is rotatably connected to the surface of the movable block 9. A water tank 14 and a water pump 15 are arranged on the left side of the tower crane body 1. The suction end of the water pump 15 is connected to the water tank 14, and the discharge end of the water pump 15 is connected to a water outlet pipe 13, and the other end of the water outlet pipe 13 is connected to a connecting pipe 12. The connecting pipe 12 is located above the movable block 9, the connecting pipe 12 is a retractable hose, and the extension length is greater than the length of the screw rod 4, so that when the second support rod 8 is bent, the connecting pipe 12 will not be torn off, and the connecting pipe 12 is connected to the fixed pipe 11.

[0024] A collecting bucket 16 is fixedly connected to the back of the tower crane body 1 through a fixing plate. The bottom of the collecting bucket 16 is connected to a water inlet pipe 17, and the other end of the water inlet pipe 17 is connected to the top of the water tank 14. In this way, rainwater can be collected by the collecting bucket 16, so that the collected rainwater can flow into the interior of the water tank 14 through the water inlet pipe 17 for collection.

[0025] A filter screen 18 is disposed inside the collecting bucket 16 , and the filter screen 18 is snap-connected with the inside of the collecting bucket 16 , which not only can filter rainwater but also facilitates subsequent disassembly and assembly of the filter screen 18 .

[0026] A movable rod 19 is fixedly connected between the left and right connecting plates 3, and the surface of the movable rod 19 is movably connected to the inner part of the bottom of the screw sleeve 6 and the movable block 9, so that the screw sleeve 6 and the movable block 9 can be auxiliary limited to facilitate their left and right movement.

[0027] The rightmost second support rod 8 is hinged to the right connecting plate 3 , so that as the movable block 9 moves, a plurality of second support rods 8 will be folded and stowed.

[0028] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0029] Working principle: During use, the water pump 15 can be started, and the water source inside the water tank 14 can be extracted, and then transported to the connecting pipe 12 through the water outlet pipe 13, and then the water source enters the interior of the nozzle 10 through the nozzle 10, and then the dust is sprayed through the nozzle 10. When the nozzle 10 is repaired and replaced, the motor 5 can be started, and the screw 4 can be driven to rotate, and the screw sleeve 6 can be driven to move to the right at the same time. During the movement, force will be applied to the first support plate 7, causing the first support plate 7 to deflect at an angle. At the same time, the second support rod 8 will also be driven by the force of the first support plate 7 to drive the movable block 9 to move together and deflect at an angle, so that several second support rods 8 and movable blocks 9 are folded, which is convenient for subsequent staff to disassemble and repair the nozzle 10.
