Abstract
The utility model relates to a novel stirring shaft leakproof structure for a concrete pump truck. The stirring shaft leakproof structure includes a baffle, a reinforced seal, a sleeve, a bearing seat and a U-shaped seal ring. The sleeve is sleeved on a shaft end of a stirring shaft of the concrete pump truck, the baffle and the bearing seat are sleeved outside the sleeve, and the baffle is fixed on the bearing seat. The U-shaped seal ring is arranged between the bearing seat and the sleeve, a lubricating grease inlet is formed in the bearing seat. The novel stirring shaft leakproof structure is characterized in that the reinforced seal is sleeved on the stirring shaft of the concrete pump truck, wherein the stirring shaft is arranged between the baffle and the bearing seat. A gap exists between the reinforced seal and the sleeve. The sealing structure has the advantages of simplifying the traditional sealing structure, reducing manufacturing costs and maintenance costs under the condition of guaranteeing enough sealing. The cost performance of the concrete pump truck is greatly improved.
Description
Technical field
The utility model relates to the field for engineering machinery, is specifically related to a kind of stirring shaft sealing configuration of new concrete pump truck.
Background technique
Concrete mixer is that concrete pumping mechanism, distributing arm support and supporting mechanism are integrated on automobile chassis, and collection travels, is pumped to the high-effective concrete conveying engineering machinery of one.The concrete lower meeting that remains static is solidified very soon, and this just needs concrete to keep motion state repeatedly in pumping procedure always, solidifies to prevent it.So need to install stirring apparatus additional to reach this purpose on the concrete mixer hopper.The stirring system sealing configuration is positioned at hopper two ends, the both sides of stirring shaft.
Stirring system needs often to contact with concrete, work under bad environment.Concrete has certain pressure to structure on two sides, if there is no sealing configuration, the long-term work meeting causes concrete to ooze out outside hopper, results in blockage.Traditional stirring seal structure complex need to reach sealing purpose with a plurality of seal rings, and can increase undoubtedly like this probability of makeing mistakes of stirring system, raises the cost.How on the basis that guarantees sealing reliability, further simplifying sealing configuration, is one of technical problem of the required solution of those skilled in the art.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem that prior art exists, design the sealing configuration of a kind of New type agitation system.Under the prerequisite that guarantees sealing reliability, solved the shortcomings such as conventional construction is complicated, high expensive, and is difficult in maintenance, but had good cost performance and operational readiness.
In order to address the above problem, the technical solution of the utility model is:
A kind of sealing configuration of new concrete pump truck stirring shaft, comprise baffle plate, reinforced seal, sleeve, bearing support, U-shaped seal ring, jacket casing is on the stirring axle head of concrete mixer, at bush outer sleeve overhead gage and bearing support, and baffle plate is fixed on bearing support, U-shaped seal ring is installed between bearing support and sleeve, bearing support is provided with the lubricating grease import, it is characterized in that: put reinforced seal on the stirring shaft of the concrete mixer between baffle plate and bearing support, and leave the gap between reinforced seal and sleeve.
The utility model also comprises a band boss round bearing, is enclosed within on the stirring shaft of concrete mixer with the boss round bearing and is arranged on the bearing support outside, and being fixed together with bearing support.
Described reinforced seal is comprised of support ring and seal ring, and support ring is integrated outside tightly being bonded at seal ring.
The material of described support ring is Carbon Steel Plate.
The material of described seal ring is nitrile butadiene rubber.
The utility model is in the embedded reinforced seal of bearing support, this reinforced seal structure is long and narrow gap together with having between axle sleeve, be used for storing lubricating grease, when lubricating grease plays lubrication, effect due to lubricated motor, lubricating grease is produced certain pressure, and this pressure is greater than the outside extruding force of concrete, can reach to prevent that concrete from entering the purpose of bearing support inside.
Band boss round bearing is used in the outside of bearing support of the present utility model, can play the bearing effect, can play the axial restraint effect again.Further simplify the assembling of part, this bearing is standard piece, and substitutability is high.
Sealing configuration advantage described in the utility model is: simplify the conventional seals structure, guaranteeing to reduce manufacture cost and later maintenance cost under enough sealing conditions.Greatly improved the cost performance of concrete mixer.
Description of drawings
Fig. 1 is the sealing configuration general illustration of the utility model pump truck stirring system.
Fig. 2 is the sealing configuration enlarged diagram at Figure 1A place.
Fig. 3 is reinforced seal structural representation of the present utility model.
The number in the figure explanation
The 1-hopper, 2-stirring shaft, 3-mixing blade, 4-baffle plate, 5-reinforced seal, 6-sleeve, 7-bearing support, 8-U RunddichtringO, 9-band boss round bearing, 10-motor bracket, 11-support ring, 12-seal ring.
Embodiment
as Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises baffle plate 4, reinforced seal 5, sleeve 6, bearing support 7, U-shaped seal ring 8, band boss round bearing 9, sleeve 6 is enclosed within on stirring shaft 2 ends of concrete mixer, at sleeve 6 overcoat overhead gages 4 and bearing support 7, and baffle plate 4 is fixed on bearing support, U-shaped seal ring 8 is installed between bearing support 7 and sleeve 6, bearing support 7 is provided with the lubricating grease import, put reinforced seal 5 on the stirring shaft of the concrete mixer between baffle plate 4 and bearing support 7, and leave the gap between reinforced seal 5 and sleeve 6, be used for storing lubricating grease, when lubricating grease plays lubrication, effect due to lubricated motor, lubricating grease is produced certain pressure, this pressure is greater than the outside extruding force of concrete, can reach and prevent that concrete from entering the purpose of bearing support inside, be enclosed within on the stirring shaft 2 of concrete mixer with boss round bearing 9 and be arranged on bearing support 7 outsides, and being fixed together with bearing support 7, using band boss round bearing 9, can play the bearing effect, can play the axial restraint effect again.Further simplify the assembling of part, this bearing is standard piece, and substitutability is high.
As shown in Figure 3, reinforced seal 5 of the present utility model is comprised of support ring 11 and seal ring 12, and support ring 11 tightly is bonded at seal ring 12 outsides and is integrated.The material of described support ring 11 is that the 08F Carbon Steel Plate has good ductility; The material of described seal ring 12 is nitrile butadiene rubber, reinforced seal 5 with bearing support 7 extrusion processes in, support ring 11 remains intact its shape.
In the middle of baffle plate 4 of the present utility model and bearing support 7 are clamped in reinforced seal 5, reinforced seal 5 left ends and sleeve 6 are tightly fitted, and prevent that concrete from infiltrating, simultaneously in the lubricating grease import of bearing support 7, there is continually lubricating grease to add, blocks the concrete that may enter.
Need to be coated with the lubricating grease of semi-drying at sleeve 6 during with stirring shaft 2 assembling, make junction plane position fit sealing, the assembling between bearing support 7 and hopper 1 is fastening need to be coated with the lubricating grease of semi-drying before equally, can prevent effectively that concrete from oozing out.
Above example is take concrete mixer as example, but this technological scheme needs the structure of excellent sealing obviously can be used in other operations the time.The above is only preferred implementation of the present utility model, is noted that can also make some improvement under the prerequisite that does not break away from the utility model principle, and these improvement also should be considered as protection domain of the present utility model.
