The utility model content
In order to overcome the deficiency that above-mentioned prior art exists, the utility model aims to provide a kind of steam turbine nut consignment balancing device, realized that assembly manipulation with the cover cap nut by the target that manually is transformed into mechanical assistance, has very advantageously improved labor productivity.
A kind of steam turbine nut consignment balancing device described in the utility model is used to assemble the cover cap nut, and it is characterized in that: it comprises hoisting ring, balance plate, balance block and rotary-tray, wherein:
Hoisting ring comprises the hook shaped component and the integrated with it body of rod, and described body of rod bottom is provided with a baffle plate;
1/2 place of balance plate length overall has the hole that can pass the described hoisting ring body of rod, and the right side in this hole has the positioning groove of presetting length;
Balance block passes described positioning groove by binding bolt and is fixed on optional position on the described balance plate;
Rotary-tray is connected the left end of described balance plate by binding bolt, and fixes by nut, and on the described rotary-tray bottom centre axle bearing is installed.
Use in the nut consignment balancing device at above-mentioned steam turbine, be with a spring that described hoisting ring and balance plate are flexibly connected between the described hoisting ring body of rod and the baffle plate.
Use in the nut consignment balancing device at above-mentioned steam turbine, the position of described balance block is by making described balance plate keep balance to be provided with put into nut in described rotary-tray after.
Owing to adopted above-mentioned technical solution, the utility model can be operated the installation of cover cap nut by the pure mechanical assistance that manually is converted into, on the one hand saved a large amount of strength, improved production efficiency on the other hand again, thereby brought huge economic benefit for enterprise to the operator.In addition, during manual operation, careless slightly or operation fatigue all might cause the generation of Peril Incident, utilizes the utility model then can thoroughly eliminate this hidden danger on the HIGHER ALTITUDE TEST FACILITY position.
Description of drawings
Fig. 1 is the structural representation of the utility model steam turbine with the nut consignment balancing device.
The specific embodiment
As shown in Figure 1, the utility model, promptly steam turbine nut consignment balancing device is used to assemble cover cap nut 10, and it comprises hoisting ring 4, balance plate 2, balance block 1 and rotary-tray 3, wherein:
Hoisting ring 4 comprises the hook shaped component 41 and the integrated with it body of rod 42, and the body of rod 42 bottoms are provided with a baffle plate 43;
1/2 place of balance plate 2 length overalls has a hole (not shown) that can pass hoisting ring 4 bodies of rod 42, and the right side in this hole has the positioning groove (not shown) of presetting length;
Balance block 1 passes positioning groove by binding bolt 7 and is fixed on optional position on the balance plate 2;
Rotary-tray 3 is connected the left end of balance plate 2 by binding bolt 7, and it is fixing to pass through nut 8, and on rotary-tray 3 bottom centre's axles 9 bearing 6 is installed.
Be with a spring 5 that hoisting ring 4 and balance plate 2 are flexibly connected between hoisting ring 4 bodies of rod 42 and the baffle plate 43.
The position of balance block 1 can make balance plate 2 keep balance to be provided with by put into cover cap nut 10 in rotary-tray 3 after.
In the utility model, the rotary-tray 3 of one end of balance plate 2 is used for supporting the cover cap nut 10 that needs installation, the bearing 6 that be equipped with rotary-tray 3 bottoms can rotate freely rotary-tray 3, thereby makes the cover cap nut 10 that is placed on the rotary-tray 3 realize screwing.The other end of balance plate 2 is balance blocks 1, and balance block 1 can slide on balance plate 2, produces when using and can balance block 1 be adjusted to the appropriate location according to the weight of cover cap nut 10, makes whole balancing device maintenance level, is convenient to install.Hoisting ring 4 can be realized being connected with driving, by spring 5 its maintenance is flexibly connected between hoisting ring 4 and the balance plate 2, so just can balance because the adverse effect that the vertical tremor in when lifting driving brings to assembling, can prevent effectively that screw thread from " killing ".
Using method of the present utility model is as follows: before using hoisting ring 4 and driving lifting hook are connected, cover cap nut 10 is placed on the rotary-tray 3, preliminary operation moves cover cap nut 10, and rotation should be nimbly and freely.The balance that whole device is looked in examination is slowly lifted by crane in driving---and find balance accurately by adjustment piece 1, and balance block 1 is locked with anti-slip.Move driving cover cap nut 10 is delivered to installed position, and make the center-aligned of cover cap nut 10 and thru-bolt, turn cover cap nut 10 makes its pretension.
The utility model especially is useful in 1,000,000 supercritical turbines, pass through the utility model, the installation of cover cap nut 10 can be operated by the pure mechanical assistance that manually is converted into, saved a large amount of strength to the operator on the one hand, improve production efficiency on the other hand again, thereby brought huge economic benefit for enterprise.In addition, during manual operation, careless slightly or operation fatigue all might cause the generation of Peril Incident, utilizes the utility model then can thoroughly eliminate this hidden danger on the HIGHER ALTITUDE TEST FACILITY position.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
