Description

Technical Field

[0001] The utility model belongs to the technical field of pump casing maintenance, in particular to a pump casing turning tool. Background Art

[0002] A circulating water pump is a device used to circulate water, so that water flows continuously in the system to achieve water circulation and supply. Circulating water pumps are usually installed in thermal power stations (thermal power centers), heat sources or cold sources, etc. In the closed loop of the heating system or air conditioning water system, the circulating water pump does not lift the water to a high place, but circulates the water repeatedly in the system to overcome the resistance loss of the loop. It has no direct relationship with the height of the building, so it is called a circulating water pump.

[0003] The pump casing of the circulating water pump is composed of two half shells that are butt-jointed, and the two half shells are connected together by bolts and nuts, and a sealing gasket is sandwiched in the middle. During the maintenance of the circulating water pump, the pump casing needs to be opened, and then turned over so that the sealing surface faces upward, the sealing surface is cleaned and the sealing gasket is replaced. Since the pump casing is relatively heavy, when turning over the pump casing, it is often carried and turned over by multiple people or using a crowbar, which can easily injure workers during the turning process, posing a safety hazard.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the pump casing needs to be turned over, the pump casing is first hoisted onto the turning plate, and then the pump casing is fixed to the turning plate by bolts. The staff then turns the handle, and the handle drives the turning plate to rotate through the turning rod, thereby turning the pump casing over, effectively avoiding the safety hazard of the pump casing hitting the staff.

[0015] (2) Before turning over the pump casing, first pull the pull ring, the pull ring drives the slider to move, the slider squeezes the spring and drives the insert to move, so that the insert is out of the locking groove, and then the handle can be turned to turn over the pump casing. When the pump casing is turned over, release the pull ring, the spring pushes the slider to move, and the slider drives the insert to insert into the locking groove, thereby limiting the rotation of the turning rod and improving the stability of the pump casing; there are multiple locking grooves around the locking disk, so the pump casing can be turned and fixed at multiple angles, which is convenient for multi-angle cleaning of the pump casing.

[0016] (3) The height of the first column can be adjusted. Pull the fixing plate, and the fixing plate drives the plug rod to move so that the plug rod is out of the socket. Then, the lifting rod can be slid upward or downward to adjust the overall height of the first column. After the adjustment is completed, release the fixing plate, and the tension spring drives the fixing plate to move. The fixing plate drives the plug rod to be inserted into the socket, and the lifting rod is locked. Therefore, the height of the first column can be adjusted according to the size of the pump casing, thereby providing a turning space for the pump casing. BRIEF DESCRIPTION OF THE DRAWINGS
