Abstract
The utility model relates to a kind of centrifugal pump impeller provision for disengagement, this provision for disengagement comprises screw rod (1), nut (2), crossbeam (3), hook (4) and detent mechanism, described nut (2) is arranged on crossbeam (3) middle part, described screw rod (1) is arranged on crossbeam (3) through nut (2), described hook (4) is combined into entirety by Connection Element and detent mechanism, is separately positioned on the crossbeam (3) of nut (2) left and right sides.Compared with prior art, the utility model structure is simple, easy to operate, and eliminate traditional-handwork and beat the potential safety hazard that impeller produces, removal efficiency is high, takes up room little, easy to carry.
Description
Technical field
The utility model relates to a kind of disassembly mechanism, especially relates to a kind of centrifugal pump impeller provision for disengagement.
Background technology
Centrifugal pump is a kind of conventional plant equipment, is widely used, and in some special dimension, because environment for use is severe, centrifugal pump impeller often suffers damage or corrodes.In order to ensure that centrifugal pump can run well, just need to change impeller, but the method for traditional dismounting impeller is mainly beats impeller by hand, not only waste time and energy, inefficiency, but also easily other parts of centrifugal pump are damaged, such as very easily damage pump shaft or impeller, thus cause very large economic loss.
Summary of the invention
The purpose of this utility model is exactly provide a kind of centrifugal pump impeller disassembly mechanism dismantled that speed is fast, operating efficiency is high and can not cause damage to other parts of centrifugal pump to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of centrifugal pump impeller provision for disengagement, this provision for disengagement comprises screw rod, nut, crossbeam, hook and detent mechanism, described nut is arranged in the middle part of crossbeam, described screw rod is arranged on crossbeam through nut, described hook is combined into entirety by Connection Element and detent mechanism, is separately positioned on the crossbeam of the nut left and right sides.
Described detent mechanism comprises locating rack and backstay, and described locating rack has screwed hole, and described backstay is provided with external screw thread, and backstay is arranged on locating rack through screwed hole.
Described Connection Element is slide block, and described hook and locating rack are weldingly fixed on slide block.
Described hook and detent mechanism realize moving left and right by slide block, for dismantling the impeller of different-diameter specification on crossbeam.
The external screw thread of described screw rod matches with the internal thread of nut.
When carrying out dismantlement work, the position of hook on crossbeam is regulated by moving slider, two hooks are made to buckle into the runner of impeller and catch on the outer rim of impeller, backstay is screwed, backstay is made tightly to withstand slide block, increase the stiction between slide block and crossbeam, thus two hooks are tightly fixed, left and right skew can not occur; Withstand on the spindle nose of impeller by the front end of screw rod again, by spanner rotary screw, screw rod produces thrust to the spindle nose of impeller, and under the continuous action of thrust, the spindle nose of impeller and impeller produce relative movement, namely can be got off by impeller demolition easily.
Compared with prior art, the utility model has following characteristics:
1. structure is simple, easy to operate, and eliminate traditional-handwork and beat the potential safety hazard that impeller produces, removal efficiency is high;
2. take up room little, easy to carry.
Accompanying drawing explanation
Fig. 1 is a kind of centrifugal pump impeller provision for disengagement of the utility model structural representation;
Description of symbols in figure:
1-screw rod, 2-nut, 3-crossbeam, 4-hook, 5-locating rack, 6-backstay.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
As shown in Figure 1, a kind of centrifugal pump impeller provision for disengagement, this provision for disengagement comprises screw rod 1, nut 2, crossbeam 3, hook 4 and detent mechanism, and nut 2 is arranged in the middle part of crossbeam 3, screw rod 1 is arranged on crossbeam 3 through nut 2, and the external screw thread of screw rod 1 matches with the internal thread of nut 2; Hook 4 is combined into entirety by Connection Element and detent mechanism, is separately positioned on the crossbeam 3 of nut 2 left and right sides.
Wherein, detent mechanism comprises locating rack 5 and backstay 6, and locating rack 5 has screwed hole, and backstay 6 is provided with external screw thread, and backstay 6 is threaded connection through screwed hole, is arranged on locating rack 5, can by rotating the position adjusting backstay 6.Connection Element is slide block, and hook 4 and locating rack 5 are weldingly fixed on slide block.Hook 4 and detent mechanism realize moving left and right by slide block on crossbeam 3, can be used for the impeller dismantling different-diameter specification.
When dismantling impeller, the position of hook 4 on crossbeam 3 is regulated by moving slider, make two to link up with 4 buckle into the runner of impeller and catch on the outer rim of impeller, backstay 6 is screwed, backstay 6 is made tightly to withstand slide block, increase the stiction between slide block and crossbeam 3, thus two hooks 4 are tightly fixed, left and right skew can not occur; Withstand on the spindle nose of impeller by the front end of screw rod 1 again, by spanner rotary screw 1, the spindle nose of screw rod 1 pair of impeller produces thrust, and under the continuous action of thrust, the spindle nose of impeller and impeller produce relative movement, namely can be got off by impeller demolition easily.
