Technical Field

The utility model belongs to the technical field of centrifugal pumps, and particularly relates to a threaded connection type impeller locking universal device for a pump.

Background

At present, when the threaded connection type impeller is assembled on a pump body, due to the lack of a special locking device, a pump shaft cannot be fixed during screwing, so that gaps which can cause movement are often left in the assembled impeller, the impeller is loosened and even falls off in the operation process of the pump, and equipment can be seriously damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a thread connection type impeller locking universal device for a pump, aiming at the defects in the prior art.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a screw thread connection type impeller locking universal device for a pump comprises a base, a track disc, an L-shaped screwing frame and an anti-rotation seat; the anti-rotation seat is connected to the base through a bolt; clamping bulges are distributed on the anti-rotation seat; a support column is arranged on the base; the bottom of the track disc is connected to the top end of the support column; a support hole is formed in the middle of the track disc; an annular track is arranged on the upper surface of the track disc close to the edge; the L-shaped screwing frame is an inverted L-shaped frame body; the upper part of the L-shaped screwing frame is provided with an inverted clamping sheet, and the lower part of the L-shaped screwing frame is provided with a guide wheel; the guide wheel is sleeved in the track of the track disc.

The shaft end part of the pump body to be provided with the impeller is connected with a coupling, and the coupling is provided with a groove; the clamping bulge of the anti-rotation seat is used for being combined with the groove so as to clamp and fix the shaft of the impeller pump body to be installed; the support column is used for supporting the track disc; the support hole is used for penetrating through and assisting in supporting the pump body of the impeller to be installed; the clamping piece at the upper end of the L-shaped screwing frame is used for clamping the impeller, and the lower end of the L-shaped screwing frame can rotate along the guide wheel.

As a further technical improvement, the vertically downward part of the L-shaped screwing frame is divided into two sections of sleeved rods which are sleeved with each other, and springs are arranged at the sleeved parts of the two sections of sleeved rods. The two sections of loop bars of the L-shaped screwing frame can be detached, when the L-shaped screwing frame is used, the upper half section of loop bar is detached, the clamping sheet is clamped into the impeller, the two sections of loop bars are combined, the impeller is placed on the corresponding rotary connection position of the pump, and the clamping sheet is pressed against the impeller under the action of the spring; in the process of rotating and clamping the impeller, the upper part of the L-shaped screwing frame gradually descends along with the screwing of the impeller; when the clamping piece is taken out, the L-shaped screwing frame needs to be pressed downwards, so that the clamping piece is separated from the impeller, and then the clamping piece is rotated reversely and can be taken out.

As a further technical improvement, the L-shaped screwing frame is also provided with a handle. The handle is used for a user to grasp and rotate the L-shaped screwing frame.

As a further technical improvement, the anti-rotation seats are divided into different sizes; the sizes of the clamping protrusions in all the sizes of the rotation preventing seat are different. The anti-rotation bases with different sizes can correspond to different couplers so as to be matched with pump bodies with different sizes to install impellers.

The use method of the threaded connection type impeller locking universal device for the pump comprises the following steps:

when the pump is used, the pump body penetrates through the rail disc through the supporting hole and is placed on the base, and the clamping protrusions on the anti-rotating seat are combined with the shaft coupling clamping position on the pump shaft to play a role in fixing the pump shaft and preventing the pump shaft from rotating; then clamping the clamping sheet of the L-shaped screwing frame into the impeller, and placing the impeller at the corresponding impeller rotating installation position of the pump body; and rotating the L-shaped screwing frame, rotating the lower part of the L-shaped screwing frame along the track through the guide wheel, simultaneously driving the impeller to screw into the corresponding mounting part, and forcibly rotating the L-shaped screwing frame until the impeller is screwed.

The technical scheme of the utility model has the following beneficial effects:

1. the pump shaft can be clamped and fixed through the anti-rotation seat, and the phenomenon that the impeller is installed insecurely due to the fact that the impeller has a play gap because the pump shaft rotates when the impeller is installed is avoided.

2. The L-shaped screwing frame can drive the impeller to rotate, so that the impeller is screwed, and compared with the method of directly screwing the impeller by hand, the L-shaped screwing frame is more labor-saving and has better screwing effect.

3. The anti-rotation seat is matched with pumps of different specifications, so that the device is wider in applicability.
