Description
Technical Field
The utility model relates to a special tool for turning a plate, in particular to a special tool for turning a vertical oblique flow circulating water pump.
Background
The circulating water pump barring tool is special maintenance equipment used during maintenance of a circulating water pump, when the circulating water pump is stopped and maintained, in order to detect the balance degree of the center and the pair wheels of the circulating water pump, a motor rotor of the circulating water pump must continuously rotate, so that the motor rotor is completely turned by manpower for maintenance of the vertical circulating water pump in a power plant for a long time, labor and labor are wasted, the safety is high, and the labor intensity of workers is high.
The motor driving end of the water pump is a rolling bearing, the non-driving end of the water pump is a sliding bearing (a guide shoe and a thrust shoe), a rotating part of the circulating water pump is dozens of tons, initial rotation starting torque is large due to the action of a sliding bearing oil film, after the rotating part rotates, the outer diameter of an elastic pin coupler used in a matched mode reaches 600mm, the outer side surface of the coupler is smooth and lacks a force borrowing point, so that at least two persons can be wound on a rolling coupler which is arranged on the outer side of the elastic pin coupler and is not stopped, the motor rotor can be ensured to rotate continuously, the mechanical barring gear is relatively troublesome to use, the maintenance period of a period of time needs to be delayed only by installation and disassembly, and the special tool for barring of the vertical inclined flow circulating water pump is simple in structure and low in manufacturing cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a special tool for turning a vertical diagonal flow circulating water pump, which solves the problem that the special tool for turning the vertical diagonal flow circulating water pump, which is simple in structure and low in manufacturing cost, is absent in the prior art.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the vertical oblique flow circulating water pump comprises a bottom plate, a handle and two plungers, wherein the front end of the bottom plate is an inwards concave arc surface, the two plungers are arranged on two sides of the front end of the arc surface in a protruding mode, the handle is arranged in the middle of the rear end of the bottom plate, the distance between the two plungers corresponds to the distance between two adjacent pin holes of an elastic pin coupling used in a matched mode of the vertical oblique flow circulating water pump, the two plungers are distributed on the circumference with the same diameter as the pin holes, and the diameter and the height of the two plungers are smaller than or equal to the diameter and the axial size of the pin holes.
In order to save more labor, the length of the handle is less than or equal to 1000 mm.
In order to prevent the hands of the turning gear from slipping and protect the hands of the turning gear, the tail end of the handle is provided with an anti-slip handle sleeve.
The utility model adopts the structure and has the following advantages:
1. the two raised plungers are arranged, the size, the distance and the distribution of the two plungers are completely corresponding to two adjacent pin holes of the elastic pin coupling matched with the vertical oblique flow circulating water pump, and the two plungers form a special turning tool corresponding to the vertical oblique flow circulating water pump, so that the integral structure is simple;
2. the effect that the rotating thrust of the turning personnel rotates is measured by introducing 'torque' in cooperation with the lengthened handle, so that the rotating parts of the coupler and the vertical oblique flow circulating water pump rotate around the circle centers of a plurality of pins of the coupler, the coupler weighing dozens of tons and the rotating parts of the vertical oblique flow circulating water pump are easily and continuously rotated by one turning personnel, the labor is saved, and the turning device is efficient and convenient;
3. the parts required by preparation can be prepared by using workshop leftover materials, and the manufacturing cost is low;
4. the utility model saves the installation or transition time of the mechanical barring gear, realizes the rapid barring with little human input and saves the cost for purchasing the mechanical barring gear.
Drawings
FIG. 1 is a schematic front view of the present invention;
fig. 2 is a right-view structural diagram of fig. 1.
In the figure, 1, a handle; 2. a base plate; 3. a plunger; 4. a handle sleeve.
Detailed Description
In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings.
As shown in fig. 1 and 2, the whole body comprises a bottom plate 2, a handle 1 and two plungers 3, the front end of the bottom plate 2 is an inwards concave arc surface, the two plungers 3 are convexly welded on two sides of the front end of the arc surface, the handle 1 is welded in the middle of the rear end of the bottom plate 2, in order to save more labor, the length of the handle 1 is less than or equal to 1000mm, in order to prevent the hands of the turning personnel from slipping, and protect the hands of the turning personnel, the tail end of the handle 1 is sleeved with an anti-slipping handle sleeve 4, the distance between the two plungers 3 corresponds to the distance between two adjacent pin holes of an elastic pin coupling used with a vertical oblique flow circulating water pump, and the plungers are distributed on the circumference with the same diameter as the pin holes, and the diameter and the axial size of the two plungers 3 are less than or equal to the diameter and the height of the pin holes.
The working principle is as follows: when the vertical diagonal flow circulating water pump jigger is overhauled, an elastic pin coupler matched with the vertical diagonal flow circulating water pump is disassembled, a half coupler connected with a shaft of the vertical diagonal flow circulating water pump is reserved, all pins are disassembled, at least two jigger personnel are matched with the turning coupler and rotating parts of the vertical diagonal flow circulating water pump, the utility model is reversely buckled after the turning up, the bottom plate 2 is arranged on the upper surface, the two plungers 3 are correspondingly inserted into two adjacent pin holes of the elastic pin coupler matched with the vertical diagonal flow circulating water pump downwards, and only one jigger personnel is required to hold the handle 1 to rotate subsequently, so that the handle 1 is pushed once per turn of the coupler to drive the coupler and the rotating parts of the vertical diagonal flow circulating water pump to rotate continuously, thereby ensuring the continuous rotation of the motor rotor.
