The mud scraper with the anti-falling device can prevent mud scrapers from falling.
Description
Technical Field
The utility model relates to a mud scraper, in particular to a mud scraper with an anti-falling device.
Background
The self weight of the mud scraper is not considered in the design of the existing mud scraper, the locking nut of the adjusting screw rod of the mud scraper is difficult to bear the weight of the mud scraper during operation, the locking nut is loosened, and the hand wheel automatically rotates reversely along with the adjusting screw rod of the mud scraper, so that the mud scraper is directly caused to fall from the pool bottom.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a mud scraper with an anti-falling device, which can prevent mud scrapers from falling.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the mud scraper with the anti-falling device comprises a mud scraper screw rod, wherein the mud scraper screw rod is in threaded connection with a hand wheel and is locked by a locking nut; a locking screw rod is arranged at a gland below the hand wheel and used for limiting the hand wheel to rotate; the screw rod of the mud scraper at the upper end of the lock nut is connected with a reverse locking nut in a threaded manner, and the reverse locking nut is in friction locking with the lock nut; or one side of the locking nut is fixed with a clamping plate, and the clamping plate is clamped with the locking screw rod.
The locking screw rod is arranged in an original threaded hole of the gland and locked by the retaining nut.
The utility model discloses a mud scraper with an anti-falling device, which has the following technical effects:
1) The anti-locking nut is additionally arranged, so that the locking nut can be prevented from loosening when the anti-locking nut is arranged, and the hand wheel is prevented from automatically reversing; in case the back locking nut is loosened, the locking screw rod can prevent the hand wheel from automatically reversing, and the double insurance can prevent the mud scraping plate from falling.
2) By adding the clamping plate on the locking nut, the clamping plate and the hand wheel can be limited by the locking screw rod, so that rotation is avoided, and the mud scraping plate can be prevented from falling.
3) The locking screw rod is directly arranged in the threaded hole of the original gland, so that the connecting and locking functions of the screw rod of the original gland can be achieved; meanwhile, the extending part can also play a limiting role, and adverse effects on the equipment are avoided.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a schematic structural view (first type) of the present utility model.
Fig. 2 is a schematic structural view (second type) of the present utility model.
Fig. 3 is a simplified diagram (first type) of the present utility model.
In the figure: the device comprises an adjusting screw rod 1, a locking nut 2, a hand wheel 3, a back locking nut 4, a mud scraper 5, a sedimentation tank 6, a locking screw rod 7, a gland 8, a clamping plate 9, a mud scraper shell 10 and a back stop nut 11.
Detailed Description
As shown in fig. 1, the mud scraper with the anti-falling device comprises a mud scraper screw 1, wherein the mud scraper screw 1 is in threaded connection with a hand wheel 3 and is locked by a locking nut 2. In the original design, the lock nut 2 plays a role in locking the screw rod 1 of the mud scraper, and the screw rod 1 of the mud scraper is adjusted in a lifting manner by rotating the hand wheel 3, so that the height of the mud scraper plate of the mud scraper is adjusted. Because the mud scraper of former design is heavier by itself, when the mud scraper of former design is in operation, lock nut 2 is difficult to bear the mud scraper weight, causes lock nut 2 not hard up to lead to hand wheel 3 automatic reversal, directly causes the mud scraper to fall the pool bottom. In order to prevent the lock nut 2 from loosening, a back-locking nut 4 is connected on the screw rod 1 of the mud scraper at the upper part of the lock nut 2 in a threaded manner, and the back-locking nut 4 is in friction locking with the lock nut 2. In order to prevent the hand wheel 3 from reversing, a bolt at the original gland 8 is removed, a locking screw rod 7 with the length of 100mm is arranged, and the locking screw rod is locked by a stop nut 11 after being screwed. The falling of the mud scraping plate is avoided from two aspects.
As shown in fig. 2, the second solution can replace the back-locking nut 4 with a clamping plate 9, and the clamping plate 9 is fixedly welded on the outer side of the locking nut 2. The clamping plates 9 can be one or more groups, and after the locking nut 2 is installed, the locking screw rod 7 is installed, and the clamping plates 9 are clamped with the locking screw rod 7. Thus, the locking screw rod 7 can simultaneously limit the rotation of the locking nut 2 and the hand wheel 3, and can also prevent the mud scraping plate from falling.
