Description

Technical Field

[0001] The invention relates to the technical field of construction machinery, in particular to a sprinkler head disassembly and assembly device. Background Art

[0002] During the construction of building fire water, it is necessary to use pipe clamps at high places to fix the sprinkler head on the end sprinkler branch pipe when tracking the sprinkler position. This is more laborious and high-altitude work is somewhat dangerous.

[0003] The existing patent CN209812210U discloses a fire sprinkler installation tool, which includes a sleeve and a long rod. The sleeve is sleeved on the long rod, and the long rod and the sleeve are slidably connected. The sleeve wall is provided with a slide groove extending in the axial direction, and one side of the slide groove is provided with a plurality of transverse transition grooves, and the transition groove is provided with a slot extending downward. A protrusion is fixed on one side of the end of the long rod located in the sleeve, and the protrusion is located in the slide groove. The protrusion and the slide groove are slidably connected, and the protrusion and the slot are engaged. A clamping assembly for driving the sprinkler head to rotate is provided on the end of the long rod away from one end of the sleeve. The sprinkler head is installed on the clamping assembly, and the handle on the rotating sleeve drives the long rod to rotate, so that the sprinkler head in the long rod clamping assembly is screwed into the installation port of the sprinkler pipe. The installer does not need to work off the ground, which has high work efficiency and reduces the danger of working off the ground. The overall length of the rod is changed by engaging the protrusion with the slots at different positions, so that sprinklers of different heights can be installed. This patent has the following defects:

[0004] 1. It is convenient to install the sprinkler head, but not convenient to remove it: when removing the sprinkler head, you need to turn the handle counterclockwise, and the protrusion can easily fall out of the slot and enter the transition slot, or even enter the slide slot, making it impossible to apply force.

[0005] 2. The clamping assembly is located at the top of the long pole, which is inconvenient to disassemble and cannot be carried around by construction workers, resulting in a narrow scope of use.

[0006] 3. For the inclined installation of the sprinkler head, it is difficult for the device to adjust the angle of the clamping assembly, resulting in the inability to use the device to install the sprinkler head in some occasions. Utility Model Content
