Technical Field

[0001] The utility model belongs to the technical field of shaft sleeves, and more specifically relates to a quick-assembly type flange connection shaft sleeve for a deep well pump. Background Art

[0002] The connecting sleeve is a sleeve-shaped part that is commonly used to connect two shafts, transmit power, bear loads and reduce friction. The connecting sleeve is generally made of high-strength, high-hardness, high-toughness and wear-resistant materials, such as alloy steel, stainless steel, brass, copper, aluminum, etc. During use, the wear of the connecting sleeve should be checked regularly, and the sleeve with severe wear should be replaced in time to avoid equipment failure and safety accidents. The connecting sleeve is also needed in the assembly process of some deep well pump flanges.

[0003] Deep-well pump flanges are typically connected and fixed to external structures to support the pump's long shaft. A sleeve is positioned between the flange and the shaft to support the shaft's rotation. Currently, the gap between the deep-well pump flange and sleeve is small, resulting in significant friction. External tools are required to remove or install the flange from the sleeve when replacing the sleeve, resulting in inefficient sleeve removal and installation. Utility Model Content

[0004] The purpose of the utility model is to provide a quick-assembly deep well pump flange connection sleeve to solve the technical problem in the prior art that when replacing the sleeve, the flange needs to be removed from the sleeve with the help of external tools, resulting in low efficiency in disassembly and assembly of the sleeve.

However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a familiar manner.

[0041] A quick-assembly flange connection sleeve for a deep well pump provided by the present invention is now described.

[0042] like Figures 1 to 3As shown, an embodiment of the utility model provides a quick-assembly deep well pump flange connection sleeve, including a flange plate 1, a sleeve accessory 2, a positioning rod 3 and an automatic connection mechanism 4; the flange plate 1 includes a flange cover 11 inside itself and a plurality of flange plates 12 connected to the outer circumference of the flange cover 11; the sleeve accessory 2 is coaxially arranged inside the flange cover 11; the positioning rod 3 is correspondingly slidably arranged in the flange plate 12, and the outer circumference of the sleeve accessory 2 is provided with a plurality of positioning grooves 21 for inserting the corresponding positioning rods 3; the automatic connection mechanism 4 is arranged in the flange cover 11, and the automatic connection mechanism 4 is used to drive the positioning rod 3 to insert into or slide out of the corresponding positioning groove 21.

[0043] The quick-assembly deep well pump flange connection sleeve provided in this embodiment, compared with the prior art, realizes the plug-in fixation between the flange plate 1 and the sleeve accessory 2 through the positioning rod 3, can increase the gap threshold between the flange plate 1 and the sleeve accessory 2, and improve the convenience when the two are assembled. The positioning rod 3 is driven to slide by the automatic connection mechanism 4 to realize the fixation and release between the flange plate 1 and the sleeve accessory 2, and ultimately improves the disassembly and assembly efficiency between the flange plate 1 and the sleeve accessory 2.

[0044] like Figures 3 and 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0045] The automatic connecting mechanism 4 includes a slider 41, a connecting spring 42, a push plate 43, a limit block 44 and a limit assembly 45; a slide groove 121 is opened on the flange plate 12, and the slider 41 is slidably set in the slide groove 121 and fixed to the corresponding positioning rod 3; the connecting spring 42 is set in the corresponding slide groove 121 and connected to the slider 41; the push plate 43 is fixed on the slider 41 and is located outside the slide groove 121; the limit block 44 is slidably set in the flange cover 11 and is extruded by the sleeve accessory 2, and the limit assembly 45 is set between each limit block 44 and the corresponding positioning rod 3; when the sleeve accessory 2 does not squeeze the limit block 44, the limit assembly 45 fixes the positioning rod 3 in a state where it is not inserted into the positioning groove 21, and the connecting spring 42 is in a compressed state; after the sleeve accessory 2 squeezes and moves the limit block 44, the limit assembly 45 cancels the restriction on the positioning rod 3.

[0046] When the shaft sleeve accessory 2 is inserted into the flange cover 11, the shaft sleeve accessory 2 squeezes the limit block 44 to make it move. The limit block 44 removes the restriction on the positioning rod 3 through the limit assembly 45. At this time, the connecting spring 42 in a compressed state drives the slider 41 and the positioning rod 3 to move, so that the end of the positioning rod 3 is inserted into the corresponding positioning groove 21, completing the automatic connection between the flange cover 11 and the shaft sleeve accessory 2. When disassembling the flange cover 11 and the shaft sleeve accessory 2, the push plate 43 is moved to drive the slider 41 and the positioning rod 3 to move. After the positioning rod 3 is separated from the positioning groove 21 and is restricted by the limit assembly 45 again, the shaft sleeve accessory 2 can be taken out, thereby improving the convenience of disassembly and assembly between the flange cover 11 and the shaft sleeve accessory 2.

[0047] like Figures 3 to 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0048] The limiting assembly 45 includes a moving block 451, a limiting spring 452, a limiting rod 453 and a clamping block 454; a plurality of moving grooves 111 are provided on the inner circumference of the flange cover 11, and the moving block 451 is slidably set in the moving groove 111 and fixed to the corresponding limiting block 44; the limiting spring 452 is set in the corresponding moving groove 111 and fixed to the moving block 451; the limiting rod 453 is slidably set in the flange cover 11 and fixed to the corresponding moving block 451, and the two grooves where the limiting rod 453 and the corresponding positioning rod 3 are located are communicated; the clamping block 454 is fixed on the corresponding positioning rod 3, and a clamping groove 4541 is provided on the side of the clamping block 454 facing the corresponding limiting rod 453; when the limiting spring 452 is in a natural state, the end of the limiting rod 453 is inserted in the clamping groove 4541, and at this time the positioning rod 3 and the positioning groove 21 are in a separated state.

[0049] When the shaft sleeve accessory 2 is inserted into the flange cover 11, the shaft sleeve accessory 2 squeezes the limit block 44 to cause it to move. The limit block 44 drives the moving block 451 and the limit rod 453 to move in a direction away from the positioning rod 3. After the end of the limit rod 453 separates from the slot 4541, the positioning rod 3 is inserted into the corresponding positioning slot 21. At this time, the limit spring 452 is in a compressed state. When disassembling the flange cover 11 and the shaft sleeve accessory 2, first push the push plate 43 to reset the sliders 41 and the limit rod 453, then remove the shaft sleeve accessory 2. At this time, the limit spring 452 drives the moving block 451 and the limit block 44 to reset, and the limit rod 453 is inserted into the slot 4541 again to facilitate the next installation of the shaft sleeve.

[0050] Furthermore, in order to further improve the convenience of operation, a component for limiting the push plate 43 can be set at each slide groove 121, such as a constriction setting at the end opening of the slide groove 121 away from the shaft sleeve accessory 2, so that when the push plate 43 drives the positioning rod 3 to move in the direction away from the shaft sleeve accessory 2, the push plate 43 can be fixed at the constriction end of the slide groove 121 with an interference fit, so that the staff can push the next push plate 43.
