Abstract
The utility model discloses an anti-vibration fixing structure for a top control rod drive mechanism fan, which comprises a cylindrical housing and fan supports, fixing blocks are arranged at the position of an air inlet of the housing, spring posts are arranged on the supports, and springs are sleeved on the spring posts; spring holddowns are fixed on the lower ends of the fixing blocks, the spring posts run through the spring holddowns, and the springs are compressed by the spring holddowns. In the anti-vibration fixing structure for the cooling fan, the spring posts are arranged on the supports, and the springs are sleeved on the spring posts; the spring holddowns are fixed on the lower ends of the fixing blocks, the spring posts run through the spring holddowns, and the springs are compressed by the spring holddowns; consequently, vibration dampers are designed for the supports of the fan body, so that the vibrational energy of the fan can be attenuated as much as possible, and thereby the normal operation and service life of the fan are guaranteed.
Description
Technical field
The utility model relates to a kind of fixed structure of axial-flow blower, the vibrationproof fixed structure of the CRDM cooling blower at a kind of nuclear reactor top of more specifically saying so belongs to and ventilates and the cooling field of engineering technology.
Background technique
Existing cooling blower is axial-flow blower mostly; Means of fixation when it uses generally is through on the casing of axial-flow blower, fixed block being set; Directly fixed block is fixed on the fan supporter through bolt; Wherein according to the mounting type different fixing piece of blower fan the position difference is set, like fixed block operated by rotary motion under the horizontal situation on the perisporium of casing, and under the vertical situation fixed block operated by rotary motion in the intake grill position of casing.Therefore above-mentioned blower fan means of fixation has had a strong impact on the operation and the working life of blower fan owing to lack the vibrationproof means.Especially for heap top cooling blower, because its quality is big, running speed is high, requires also higher relatively to vibrationproof.
The model utility content
To above-mentioned situation, the control rod drive that it is good that the problem that the utility model quasi-solution is determined provides a kind of vibration-isolating effect is piled the vibrationproof fixed structure of machine vibrationproof fixed structure against the wind, to guarantee the normal operation and the working life of blower fan.Especially be fit to the fixing of heap top cooling blower.
For achieving the above object; The utility model adopts following technological scheme: a kind of control rod drive is piled machine vibrationproof fixed structure against the wind; It comprises columnar casing and fan supporter; Intake grill position at said casing is provided with fixed block, and said support is provided with spring stack, is with spring on the said spring stack; The underpart fixing spring briquetting of said fixed block, said spring stack passes spring lock block, and spring lock block is pressed on the spring.
The periphery of said spring is provided with the spring protection sleeve pipe.
Adopt technique scheme, the control rod drive of the utility model is piled machine vibrationproof fixed structure against the wind, because support is provided with spring stack, is with spring on the said spring stack; The underpart fixing spring briquetting of said fixed block, said spring stack passes spring lock block, and spring lock block is pressed on the spring.Make like this blower fan body supported design vibration damping equipment, make the vibrational energy of blower fan self be able to decay as far as possible, to guarantee the normal operation and the working life of blower fan.
Description of drawings
Fig. 1 is that the utility model control rod drive is piled the schematic representation of machine vibrationproof fixed structure against the wind;
Fig. 2 is the structural representation that Fig. 1 overlooks direction.
Among the figure: 1-casing, 2-fan supporter, 3-intake grill, 4-fixed block, 5-spring stack, 6-spring, 7-spring protection sleeve pipe, 8-spring lock block.
Embodiment
Like Fig. 1, shown in Figure 2, the utility model control rod drive is piled machine vibrationproof fixed structure against the wind, and it comprises columnar casing 1 and fan supporter 2, is provided with fixed block 4 in intake grill 3 positions of said casing 1.Fixed block 4 quantity of present embodiment are four, and certainly according to actual conditions, fixed block 4 can also be other quantity.Said support 2 is provided with spring stack 5, is with spring 6 on the said spring stack 5.
The underpart fixing spring briquetting 8 of said fixed block 4, said spring stack 5 passes spring lock block 8, and spring lock block 8 is pressed on the spring.
In addition, the utility model control rod drive is piled machine vibrationproof fixed structure against the wind, and the periphery of said spring 6 is provided with spring protection sleeve pipe 7.Can increase protection like this, improve safety in utilization simultaneously spring 6.
