Abstract
The utility model discloses a novel fire monitor slewing mechanism. The novel fire monitor slewing mechanism comprises a shell and a worm wheel, wherein the shell is sleeved outside a fire monitor body; the worm wheel is positioned between the shell and the fire monitor body; the worm wheel is fastened on the fire monitor body in a matched manner; the worm wheel is matched and meshed with a worm; and a bearing piece is arranged between the shell and the fire monitor body and matched with the shell and the fire monitor body. Compared with the steel beads in the prior art, the bearing piece can reduce the friction resistance in the rotation action of the slewing mechanism, so the rotating action of the slewing mechanism can be smooth and effective. Most importantly, the bearing piece can be in tight fit with the shell and the fire monitor body, so the defect of displacement or sliding of the slewing mechanism in the rotating and positioning action is overcome and the rotating and positioning precision of the fire monitor is greatly improved. Due to the improved design that the conventional steel beads are replaced by the bearing piece, great convenience is provided for assembly and maintenance of the fire monitor.
Description
Technical field
The utility model relates to a kind of fire monitor, specifically is meant a kind of novel fire monitor slew gear.
Background technology
The slew gear of fire monitor is the important mechanical composition parts of fire monitor one; The height that rationally reaches precision of its structural design; Directly affect the running accuracy and the positioning accuracy thereof of fire monitor, therefore, design a kind of slew gear rational in infrastructure, easy to assembly, that precision is high and have great importance.
For running and the auto-lock function thereof of realizing fire monitor; The slew gear of existing fire monitor generally adopts worm gear and worm screw to carry out transmission; The shell body of slew gear is nested with outside barrel; The adaptive barrel place that is fastened on correspondence in the shell body of worm gear, the suitable engagement of worm and wheel, the activity of the two cooperates the turning effort that has realized barrel by this; In order to reduce the frictional force between shell body and barrel, the method that adopts usually is between shell body and barrel, to add steel ball; Yet, utilize the reduce friction effect of resistance of steel ball good inadequately in the practical application, and this kind method also exists following deficiency: at first to be that assembly process is more loaded down with trivial details; And load onto after the steel ball; Whole slew gear is difficult to dismounting, must from slew gear, all take out steel ball earlier, just can carry out the dismounting of slew gear; Therefore, brought great difficulty for the assembling maintenance of fire monitor; There is the most important to be again; The assembling of steel ball for ease; It is bigger that the shell body of slew gear and the gap between the barrel need be provided with, and then sliding or the displacement problem appears in rotation and location action in slew gear easily, thereby reduced the running accuracy and the positioning accuracy of fire monitor.
In view of this, the inventor furthers investigate to the slew gear problem of existing fire monitor, and this case produces thus.
The utility model content
The purpose of the utility model is to provide a kind of novel fire monitor slew gear, and it has reduced the frictional resistance problem that exists in the slew gear rotation better, has rotation, positioning accuracy height, assembles, safeguards advantages such as simple.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of novel fire monitor slew gear; Comprise be nested with the shell body outside the fire-fighting barrel and be positioned at above-mentioned shell body and above-mentioned fire-fighting barrel between worm gear; This worm gear is adaptive to be fastened on the above-mentioned barrel; The suitable engagement setting of this worm gear and a worm screw is provided with the bearing part of the two suitable setting with this between above-mentioned shell body and above-mentioned fire-fighting barrel.
Above-mentioned bearing part is provided with two altogether, lays respectively at above-mentioned worm gear at the dual-side place on the axial direction of above-mentioned fire-fighting barrel.
Corresponding above-mentioned worm gear position offers the hydraulic fluid port that supplies lubricating oil to insert on the above-mentioned shell body.
The dual-side of above-mentioned shell body radial direction of above-mentioned fire-fighting barrel on the edge is equipped with a supporting lid and a valve body respectively, is respectively equipped with the seal that is used to seal between this supporting lid, valve body and above-mentioned fire-fighting barrel.
After adopting such scheme; A kind of fire monitor slew gear of the utility model; It is provided with the bearing part of the two suitable setting with this between shell body and barrel, compare with the available technology adopting steel ball, and bearing part can reduce the frictional resistance problem that slew gear exists better in spinning movement; Then the spinning movement of slew gear can be smooth and easy effective again, but also alleviated the pressure that worm gear, worm screw are born in transmission; The more important thing is that said bearing part can more closely cooperate with shell body and fire-fighting barrel, it has avoided slew gear in rotation and location action, to have displacement or slip defects, has improved the rotation and the positioning accuracy of fire monitor thus greatly; Have again, the improvement design of the existing steel ball of this novel employing bearing part replacement, its I& M of giving fire monitor is bringing great convenience property also.

The specific embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Be illustrated in figure 1 as a kind of novel fire monitor slew gear that the utility model relates to; It includes fire-fighting barrel 1, shell body 2, worm gear 3 and worm screw 4; Shell body 2 adaptive being nested with outside fire-fighting barrel 1; Worm gear 3 is positioned at shell body 2 and 1 of fire-fighting barrel and is fastened on the fire-fighting barrel 1, and worm screw 4 and worm gear 3 suitable engagement settings and worm screw 4 stretch out that shell body 2 is outer to supply external operating parts to be connected; Thus, through handling said operating parts,, realized the rotation and the positioning action of fire-fighting barrel 1 opposite shell body 2 via the mutual transmission mating reaction of worm screw 4, worm gear 3.
This novel main innovate point is; Be provided with the bearing part 7 of the two suitable setting with this in said shell body 2 and 1 of fire-fighting barrel; In the preferred embodiment, this bearing part 7 is provided with two altogether, lays respectively at worm gear 3 along the dual-side place on the axial direction of fire-fighting barrel 1; Compare with the available technology adopting steel ball; This case bearing part 7 can reduce the frictional resistance problem that slew gear exists better in spinning movement; Then the spinning movement of slew gear can be smooth and easy effective again, but also alleviated the pressure that worm gear 3, worm screw 4 are born in transmission; The more important thing is that said bearing part 7 can more closely cooperate with shell body 2 and fire-fighting barrel 1, it has avoided slew gear in rotation and location action, to have displacement or slip defects, has improved the rotation and the positioning accuracy of fire monitor thus greatly; Have again, the improvement design of the existing steel ball of these novel employing bearing part 7 replacements, its I& M of giving fire monitor is bringing great convenience property also.
