Abstract
The utility model relates to a hoisting sheave body of a shaft hoist, in particular to a hoisting sheave body with a destressing structure of the shaft hoist. The hoisting sheave body comprises a wheel rim (3), a wheel disk (4), rib plates (1 and 2) and a wheel hub (6), wherein the wheel disk (4) and the rib plates (1and 2) are arranged between the wheel rim (3) and the wheel hub (6), the rib plates (1and 2) are fixedly connected to the surface of the wheel disk, and the wheel rim (3), the wheel disk (4) and the rib plates (1and 2) are fixedly connected with one another to form an integrated structure in a welded mode. The hoisting sheave body with the destressing structure is characterized in that a destressing hole (5) is formed in the common welding joint of the wheel rim (3), the wheel disk (4) and the rib plates (1and 2). Because the welding stress can be released through the destressing hole, stress concentration at the welding position is avoided, so that product quality is improved and service life of the hoisting sheave is prolonged.
Description
Technical field
The utility model relates to a kind of head sheave wheel body of mining elevator, relates in particular to a kind of head sheave wheel body with destressing structure of mining elevator.
Background technology
Head sheave is to be the device of steel rope guiding in mine lift machine operation, and existing mining elevator head sheave comprises wheel hub, is evenly equipped with multiple spokes around wheel hub, is connected with wheel rim on spoke, and wheel hub, spoke, wheel rim are integrated cast structure.Owing to adopting integrally casting structure, this head sheave intensity difference,, is easily damaged when excessive when stressed, causes safety misadventure.
For improving intensity, the normal wheel hub, the wheel rim of casting and the spoke that section bar is made that forge of adopting welds respectively, the wheel rim circle that is arranged in juxtaposition of two of causes of wheel be placed in the attaching parts in wheel rim circle inside and outside be welded, owing to cannot weld the inside and outside side of wheel rim simultaneously, can only weld respectively in order the inside and outside side of wheel rim, the deformation quantity being caused by welding stress is large, easily causes wheel rim to scrap.And existing welded structure, makes head sheave in long-term use procedure, easily occurs endurance crack in wheel rim, disc and the welding concentration zones, floor place of head sheave wheel body, also has potential safety hazard.
Utility model content
The utility model is based on the problems referred to above, and the head sheave wheel body with destressing structure that stress is concentrated is provided while providing a kind of wheel rim, disc and floor of avoiding head sheave wheel body to be in welding.
For solving the problems of the technologies described above, the head sheave wheel body with destressing structure of the present utility model adopts following structure:
There is the head sheave wheel body of destressing structure, comprise wheel rim, disc, floor and wheel hub, disc, floor are connected between wheel rim and wheel hub, floor is fixedly connected on disc surface, between described wheel rim, disc and floor by the welding manner structure that is connected to one, wherein, offer destressing hole at the common place of being welded to connect of wheel rim, disc and floor.
Further, described destressing hole at least forms by removing disc material.
Further, described hole is semicircle orifice, and its center of circle is roughly positioned on wheel rim.
Further, described floor is included as T font, comprises being welded to connect with disc and from disc surface along the first outstanding floor of head sheave axial direction and second floor vertical with the first floor.
Owing to adopting said structure, at wheel rim, disc and floor, the common place of being welded to connect offers destressing hole, make in the time that wheel rim, disc and floor are welded as a whole, welding stress discharges by described hole, avoiding forming stress at weld concentrates, improve product design, extended the service life of head sheave.
Brief description of the drawings
The head sheave wheel body that accompanying drawing 1 is made for existing employing welding manner is along the diametric cutaway drawing of head sheave;
The front view of the head sheave wheel body that accompanying drawing 2 is made for existing employing welding manner;
Accompanying drawing 3 is for the head sheave wheel body that the utlity model has destressing structure is along the diametric cutaway drawing of head sheave;
Accompanying drawing 4 is the front view that the utlity model has the head sheave wheel body of destressing structure.
Wherein, 1-the second floor, 2-the first floor, 3-wheel rim, 4-disc, 5-destressing hole, 6-wheel hub
Detailed description of the invention
Below with reference to Figure of description, the utility model is elaborated.
1-4 by reference to the accompanying drawings, head sheave wheel body comprises wheel rim 3, disc 4, the first floor 2, the second floor 1 and wheel hub 6, disc 4, the first floor 2, the second floor 1 are connected between wheel rim 3 and wheel hub 4, the first floor 2 and the second floor 1 are configured to T font, the first floor 2 is welded to connect with disc 4 and is outstanding from disc 4 surfaces along head sheave axial direction, and the second floor 1 is with first floor 2 is vertical is connected.
Described wheel hub is conventionally with forging molding, wheel rim 3 castings, disc 4, the first floor 2, the second floor 1 are made with section bar, above-mentioned parts are connected to an integral structure by welding manner, it is the radially interior outer surface of disc 4, the radially both ends of the first floor 2, the second floor 1 are welded to connect with wheel rim 3, wheel hub 6 respectively, and the first floor 2 is welded to connect by its opposite side relative with the first floor 1 and disc 4.
In existing day wheel construction, easily producing stress at the common place of being welded to connect of wheel rim 3, disc 4 and floor concentrates, the utility model is by forming herein destressing hole, thereby the stress that welding can be produced while welding at this place be released by this destressing hole, thereby having avoided forming stress at weld concentrates, improve product design, extended the service life of head sheave.
Described destressing hole 5 can form by removing disc material, or removes part to should hole part material being also set on the first floor 2, further to improve stress concentration phenomenon.
Described destressing hole 5 is for being preferably semicircle orifice.The center of circle of semicircle orifice can roughly be positioned on wheel rim, and destressing hole can be also other shapes, for example arcuate socket, and its size is specifically selected according to concrete head sheave size and dimension.
