Abstract
The invention relates to a novel floating supporting oil cylinder. The novel floating supporting oil cylinder comprises a cylinder body, a thrust bearing, a supporting base, a machine frame, a flat bottom connecting flange and a lifting lug plate, wherein the supporting base is fixedly arranged on the machine frame; the thrust bearing is arranged on the supporting base; the flat bottom connecting flange is arranged on the thrust bearing and is fixedly arranged on the upper part of the cylinder body; the lifting lug plate is fixedly connected to the flat bottom connecting flange. Due to the fact that the thrust bearing substitutes a spherical connecting flange, processing is convenient to perform; an oil groove is not required to be machined in the supporting base; the slide thrust bearing with a self-lubricating spherical surface has friction reducing property, abrasion resistance and self-lubrication characteristic, and meanwhile the thrust bearing has relatively good size stability and relatively high bearing capacity. Maintenance in the future is also convenient to perform, the thrust bearing can be directly taken out for maintenance only by lifting an oil cylinder by a lifting appliance, the service life of the hydraulic oil cylinder is guaranteed, and the usability is also improved.
Description
Technical field
The present invention relates to hydraulic hoist technical field, especially a kind of novel float support oil cylinder.
Background technique
In recent years, bulkhgead gate is used in Hydraulic and Hydro-Power Engineering more and more widely.Along with expanding economy and progress, gantry gate hoists are progressively eliminated, and emerging hydraulic hoist emerges.Bulkhgead gate divides access door to follow accident door, as run into the generation of maintenance or accident, just needs closed shutter, it can thus be appreciated that, the significance of hydraulic jack.
Society is in development, and hydraulics also needs development, only has continuous development, and our hydraulic jack just can obtain increasingly extensive application.
This type of hydraulic jack is vertically installation and is do not close a power, and traditional Placement first welds bottom on cylinder body top for spherical adpting flange, flange welds 2 shackle plates for lifting.Be transported to after site until goods, first frame be installed on the platform of required elevation, then be connected with the shackle plate on adpting flange by suspender suspension hook, being sling by whole oil cylinder is connected with prior mounted frame.Because oil cylinder is be that spherical adpting flange is connected with frame bearing by bottom with frame, what oil cylinder can be slight floats, so maintenance is in the future essential, needs regularly by the oilhole oil injecting lubricating on frame bearing.
Summary of the invention
The technical problem to be solved in the present invention is: need intermittent oiling to solve existing bulkhgead gate hydraulic jack, and the problem that spherical flange easily weares and teares, a kind of novel float support oil cylinder is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel float support oil cylinder, comprise cylinder body, thrust-bearing, bearing, frame, flat adpting flange and shackle plate, described thrust-bearing comprises seat ring and blowout patche, described bearing is fixedly installed in described frame by welding or bolt etc., described seat ring elastic conjunction is on described bearing, described flat adpting flange elastic conjunction is on blowout patche, described flat adpting flange is by being welded and fixed the top being arranged on described cylinder body, described shackle plate is fixedly connected by welding on described flat adpting flange, only need keep in repair goods during maintenance and change thrust-bearing.
The invention has the beneficial effects as follows: the form of adpting flange is optimized, and brings convenience to processing; Also without the need to processing oil groove on bearing; Lubricate-free sphere slide thrust bearing has anti-attrition, wear resistance, self lubricity, also has good dimensional stability simultaneously, higher bearing capacity.And under the condition having lubrication, performance can be greatly improved, and can increase the service life.Meanwhile, the existence of lubricating grease, also can improve sealing and antiseptic property; Lubricate-free sphere slide thrust bearing effectively seals and can anti-sealing and silt enter, and can effectively prevent lubricant medium to run off; For later Maintenance and Repair are provided convenience.Thus ensure that the working life of hydraulic jack, also improve usability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described;
Fig. 1 is the structural representation that the present invention is connected with frame;
Fig. 2 is thrust bearing schematic diagram of the present invention;
In figure: 1. cylinder body, 2. thrust-bearing, 3. bearing, 4. frame, 5. flat adpting flange, 6. shackle plate.7. seat ring, 8. blowout patche.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of novel float support oil cylinder as shown in Figure 1, Figure 2, comprise cylinder body 1, thrust-bearing 2, bearing 3, frame 4, flat adpting flange 5 and shackle plate 6, described thrust-bearing comprises seat ring 7 and blowout patche 8, described bearing 3 is fixedly installed in described frame 4 by welding or bolt etc., described seat ring 7 elastic conjunction is on described bearing 3, described flat adpting flange 5 elastic conjunction is on blowout patche 8, described flat adpting flange 5 is by being welded and fixed the top being arranged on described cylinder body 1, and described shackle plate 6 is fixedly connected by welding on described flat adpting flange 5.Be preferable over lubricate-free sphere slide thrust bearing.Safeguard also very convenient, only need be sling by cylinder body 1 by suspender, thrust-bearing 2 directly can take out maintaining in the future.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
