Detailed Description
The invention will be described in detail below with reference to the drawings and the detailed description.
The invention relates to a mounting device for a vibration detection sensor of a hydroelectric generating set or a wind generating set, which is structurally shown in fig. 2 and comprises an adjustable spanner fixing plate 4 which is arranged vertically, wherein the upper end of the right side of the adjustable spanner fixing plate 4 is fixedly provided with a horizontal handle 6, the left side of the adjustable spanner fixing plate 4 is fixedly connected with a clamping key box 2 through a connecting piece 3, the left side of the clamping key box 2 is rotatably provided with a clamping key knob 1, the clamping key knob 1 extends into the clamping key box 2 from the left side of the clamping key box 2 and then is connected with a transmission device, the lower end of the transmission device is connected with a clamping key 9, the transmission device changes the rotation of the clamping key knob 1 into the up-down motion of the clamping key 9, the left side of the adjustable spanner fixing plate 4 is also connected with a fixed spanner 8 through a connecting piece a10, the lower end of the clamping key 9 is clamped into the upper end of the fixed spanner 8, as shown in fig. 3, the adjustable spanner fixing plate 4 is also provided with a clamping groove 5, and the movable spanner 7 is slidably mounted in the clamping groove 5.
The connection member a10 and the connection member 3 are provided in a rod shape, and the lengths of the connection member a10 and the connection member 3 are the same as the thickness of the auxiliary angle 11.
As shown in fig. 4-5, the transmission device comprises a gear shaft 2-1 rotationally fixed in a key clamping box 2, the gear shaft 2-1 is fixedly connected with a key clamping knob 1, a gear 2-2 is fixedly installed on the gear shaft 2-1, a rack 2-3 is meshed on the gear 2-2, and the lower end of the rack 2-3 extends out of the lower end of the key clamping box 2 and is connected with a key clamping 9.
The upper end of the fixed spanner 8 is provided with a groove 8-1 which is matched with the shape of the clamping key 9, and the lower end of the clamping key 9 extends into the groove 8-1.
A bolt 12 is arranged in the clamping groove 5, the bolt head of the bolt 12 is positioned at one side of the clamping groove 5 close to the fixed spanner 8, and a screw rod of the bolt 12 extends out of the clamping groove 5 and penetrates through the adjustable spanner 7 to be connected with a nut.
The fixed spanner 8 is a double offset ring spanner, and the adjustable spanner 7 is an open-end spanner.
The fixed spanner 8 and the movable spanner 7 are correspondingly arranged.
As shown in fig. 1, when the sensor is installed in the prior art, an installer must fix the left nut all the time by using a fixed wrench, and then screw the right nut by using an adjustable wrench by the other hand at the same time, which is very inconvenient.
The working principle of the invention is as follows: firstly, the adjustable spanner 7 is taken down from the bolt 12, and then the clamping key 9 is retracted and placed in the clamping key box 2 through the clamping key knob 1; as shown in fig. 6, when the sensor is installed, the nuts at the two ends of the sensor are screwed on the front side and the rear side of the auxiliary angle steel 11, then the nuts close to the large shaft are fixed by the fixed wrench 8, and then the fixed wrench 8 is locked by rotating the clamping key knob 1 to extend the clamping key 9 into the groove 8-1 of the fixed wrench 8, so that the nuts at the position far from the large shaft are prevented from rotating together when rotating; secondly, sleeving the adjustable spanner 7 on a nut far away from the large shaft, and sleeving the tail part of the adjustable spanner 7 on the bolt 12, so that the effectiveness of the movement track of the adjustable spanner when locking the nut is ensured; after the sensor nuts at the two ends of the auxiliary angle steel 11 are fixed, a tester fixes the handle 6 by one hand, and can operate the adjustable wrench 7 by the other hand, so that the nuts at the two ends of the sensor are quickly locked, and meanwhile, when the gap between the sensor and the large shaft is adjusted, the gap can be quickly adjusted in place through the device, so that the installation efficiency of the tester is ensured. After the sensor is well, the device is detached through the reverse sequence, so that the device is ready for the installation of the next sensor, and when the nut is locked, an installer operates at the outer side, so that the device is not limited by narrow space.
Because the sensor is installed in a narrow space, a wrench close to the large shaft is designed as a fixed wrench, and a wrench far away from the large shaft and close to a tester is designed as a detachable adjustable wrench for one-time installation of the sensor. When the sensor is installed, the adjustable spanner moves in the clamping groove 5, so that the effectiveness and the quick action of the spanner in working in a narrow space are ensured, and a better auxiliary effect is provided for correctly and quickly installing the sensor.
The device is mainly used in narrow spaces such as thrust bearings, upper guide bearings and the like of a vertical unit, and the bearings are supporting parts of a hydroelectric unit and are used for restraining a main shaft of the water turbine and a large shaft of a generator from rotating within a specified range so as to ensure the running stability of the unit. The degree of yaw measured during operation includes the degree of static deformation, dynamic deformation of the rotor axis and the degree of deviation of the dynamic axis from the original equilibrium position. During testing, it is necessary to mount the sensor as close as possible to the bearing shell, which is typically located at the shafting location at the bearing, since the shell is sealed inside the bearing.
