Detailed Description
The utility model provides a quick dismounting device for a pressure screen, which is used for making the purposes, technical schemes and effects of the utility model clearer and more definite, and is further described in detail below. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 4, the present utility model provides a quick dismounting device for a pressure screen of a paper machine. The drawings are only for the purpose of illustrating the structural principles and are not to scale for actual products. For ease of understanding, the cylinder 91 and top cover 92 of the pressure screen are schematically depicted in fig. 1.
The quick dismounting device for the pressure screen of the paper machine comprises at least one support 1, a screw rod lifting mechanism, a cantilever rod 32 and a hanging ring 51; the screw rod lifting mechanism comprises a guide post 21, a hand wheel 22, a screw rod 23 and a lifting seat 24, and the guide post is connected with the support; the cantilever rod is connected with the lifting seat, and the end part of the cantilever rod is provided with a hook 41; the hanging ring 51 is arranged on a mounting seat 52, and the hook is used for being connected with the hanging ring.
When in actual use, the screw rod is driven to rotate by rotating the hand wheel, the screw rod does not move up and down relative to the guide post, but the lifting seat can move up and down relative to the guide post (the lifting seat does not rotate). Only the bottom end of the lifting seat is observed in the drawing, and the main body part of the lifting seat (which cannot be directly observed) is connected with a screw-nut (not shown in the drawing) or is arranged as a whole with the screw-nut. It should be noted that, the screw rod lifting mechanism is in the prior art, so the internal structure of the screw rod lifting mechanism is not specifically drawn in the drawings.
Further, a section of sleeve 31 is connected to the root of the cantilever 32, and the sleeve is sleeved on the lifting seat. Bearings (not visible from the view of the drawing) can be arranged between the lifting seat and the sleeve, so that the sleeve can rotate relative to the lifting seat.
Further, the cantilever bar gradually decreases in width from the root to the end. The setting has improved the atress scope of cantilever arm, and the root is difficult to break.
Preferably, the root width of the cantilever beam is not less than half the height of the sleeve. In practice, if the strength of the cantilever beam is to be maximized, the width of the root portion of the cantilever beam may be made equal to the height of the sleeve.
Preferably, the hook 41 is a U-shaped hook; the end of the cantilever rod passes through a root bolt 42 which passes through the two tips of the clevis.
Preferably, two holders are provided in total. By arranging two supports, the connection stability of the screw rod lifting mechanism and the supports is improved. Each of which locks the guide post by means of a set-back bolt 12, respectively.
Preferably, each support is provided with a round hole, and the guide post passes through the round hole; the support is provided with a locking bolt for locking the guide post.
In actual use, the support is fixedly connected (preferably welded) on the side wall of the pressure screen cylinder, and the mounting seat is fixedly connected (preferably welded) on the top of the pressure screen top cover. The U-shaped hook penetrates through the hanging ring, and then the bolt of the U-shaped hook is locked. The bolts between the top cover of the pressure screen and the cylinder are detached, then the hand wheel is operated to enable the lifting seat and the cantilever rod to ascend, and the top cover of the pressure screen is lifted; turning the boom 180 degrees may then turn the hand wheel to lower the lifting seat and boom bar, thereby placing the pressure screen at the designated location. When the pressure screen top cover is reinstalled, the above sequence of actions is reversed and will not be repeated here.
According to the analysis, the quick dismounting device for the pressure screen of the paper machine provided by the utility model has the advantages of simple structure, lower cost and easiness in manufacture and operation. Because the occupied space is small, the pressure screen can be directly arranged on the cylinder body of the pressure screen without moving the existing equipment of the workshop. The problem that lifting equipment such as crown blocks and hoist blocks are installed in workshops in insufficient space and the pressure screen top cover is required to be lifted and transferred forcibly by manpower is thoroughly solved, the labor intensity is reduced, the working efficiency is improved, the potential safety hazard in the disassembly and assembly process is greatly reduced, and the personal safety of workers is guaranteed.
It will be understood that equivalents and modifications will occur to those skilled in the art based on the present utility model and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present utility model.
