Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a frock is demolishd to power plant's pipeline filter screen, includes connecting block 1, and female screw cover 2 is equipped with to the inside of connecting block 1, and the inside processing of female screw cover 2 has interior screw thread, and the upper end is fixed with hand wheel 3, and the internally mounted of female screw cover 2 has adjusting screw 4, and adjusting screw 4 through connection female screw cover, and adjusting screw 4 lower part is provided with the centre gripping subassembly. The female screw sleeve can rotate inside the connecting block. Insert centre gripping subassembly 6 in power plant's pipeline filter screen, then rotate hand wheel 3, the hand wheel drives the rotation of female screw cover 2, makes adjusting screw 4 move down, drives dwang 69 and changes the angle to make spring 62 receive the extrusion, have elastic potential energy, the horizontal contained angle of dwang diminishes, thereby struts grip block 61 to both sides, and then supports fixedly the inner wall of filter screen, then upwards stimulates hand wheel 3, takes out the filter screen from the filter.

Wherein, connecting block 1 is connected with centre gripping subassembly 6 through telescopic link 5, and telescopic link 5 is used for controlling centre gripping subassembly 6's shift position.

Wherein, centre gripping subassembly 6 includes grip block 61, mounting groove 62, spring 63, sliding block 64, kicking block 65, regulating block 66, dwang 67, stopper 68 and spacing groove 69,

grip block

61 and 6 fixed connection of telescopic link, mounting groove 62 has been seted up to grip block 61's inside, spring 63 has been placed to the inside of mounting groove 62, spring 63's top is fixed on sliding block 64, the bottom mounting is on kicking block 65, sliding block 64 and grip block 61 sliding connection, sliding block 64 and regulating block 66 fixed connection, it is connected with dwang 67 to rotate on the regulating block 66, the bottom and the grip block 61 of dwang 67 rotate to be connected, dwang 67 is provided with two, cross arrangement just rotates through stopper 68 to be connected, stopper 68 has two, through wearing the round pin centre gripping in spacing groove 69 both sides, the spacing groove is seted up at the middle part of dwang. Adjusting screw moves down for the horizontal contained angle of dwang 67 diminishes, thereby makes spring 63 receive the extrusion, and the extension of telescopic link 6 this moment, thereby struts grip block 61, and then supports fixedly the inner wall of filter screen.

Wherein, grip block 61 is provided with two, and the rubber pad is installed to the outside, strengthens grip block 61 and filter screen inner wall connection's stability.

Wherein, the distribution of grip block 61 symmetry is in the both sides of dwang 67, drives grip block 61 through dwang 67 and does shrink and expansion work.

Wherein, install the rubber sleeve on the hand wheel 3, there is rubber granule on the rubber sleeve surface, increases the frictional force between user's hand and the hand wheel 3.

The working principle is as follows: when using, insert the centre gripping subassembly 6 in the power plant's pipe-line filter screen, then rotate hand wheel 3, hand wheel 3 drives the 2 rotations of female screw cover, makes adjusting screw 4 move down, drives dwang 67 change angle to make the spring receive the extrusion, have elastic potential energy, the horizontal contained angle of dwang diminishes, thereby struts grip block 61 to both sides, and then supports fixedly the inner wall of filter screen, then outside pulling hand wheel 3, takes out the filter screen from the filter. And the hand wheel 3 is rotated reversely, the adjusting screw rod 4 moves upwards, and the rotating rod is driven to reduce and increase the horizontal angle. The spring 63 will then return to its original position, moving the slide block 64 upwards, returning the pivot rod 67, and retracting the clamping plate towards the centre, thereby withdrawing the clamping assembly from the screen.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
