Abstract
The utility model discloses a central articulated device of a carry scraper, in order to solve the problem that a ball articulated type is adopted for the central articulated device of the carry scraper, the concentricity of upper and lower articulated pin holes is low. The central articulated device of the carry scraper comprises an upper pressing cover, a lower pressing cover, a middle articulated pin shaft, a front rack middle articulated tongue plate and a rear rack middle articulated tongue plate, wherein the rear rack middle articulated tongue plate is centrally provided with a dual-column of conical roller bearing; the upper pressing cover and the lower pressing cover are respectively connected with the front rack middle articulated tongue plate through bolts. According to the utility model, the dual-column conical roller bearing capable of loading radially and axially in combination and bearing radial load mainly is adopted; the stress condition change is favorable; front and rear carframes are high concentricity, are compact in structure, and moreover are more flexible in deviation. The central articulated device of the carry scraper is favorable in lubrication, is high in external damage resistance capability, and is low in maintaining quantity.
Description
Technical field
The utility model relates to a kind of scraper member, is specifically related to the central articulated mounting of a kind of scraper.
Background technology
The effect one of scraper central authorities articulated mounting is for connecting scraper front and back frame, effect two is because the special working environment of scraper, pivotally connected frame is in order at utmost to realize the scraper turning, reduce the scraper turning radius, make scraper narrow and small environment realization turning in the down-hole, improve the flexibility of scraper action.It with the advantage that whole car fare is compared is: 1, turning radius is little, turns to flexibly, aims at easily stockpile during work; 2, compact conformation, lightweight, highly sensitive, turn to light.Since the scraper work under bad environment, humid environment, and muddy water is many, road is uneven, and shovel frame is stressed before and after during the ore deposit concentrates on central hinged place, therefore the spoilage of central articulated mounting is higher, therefore the structure design of central articulated mounting is very crucial for the service behaviour quality of scraper.Because it is large to keep in repair central articulated mounting difficulty, repair density is high.
The central articulated mounting of former scraper belongs to ball-and-socket hinge style, although adopt ball-and-socket hinge style can make the hinging pin shaft stressing conditions obtain taking a turn for the better, the concentricity of upper and lower hinged pin-and-hole is low.Therefore in use there is following shortcoming and defect in this device: 1, because subsurface environment is moist, work plane muddy water is many, environment on coalface is abominable, the front and back frame central authorities hinged steering mechanism of scraper uniqueness, determined that the suffered impact force in central hinged place, shearing force are relatively concentrated and power is large, add the up and down not high reason of axiality of the congenital insufficient lubrication of ball joint bearing, hyoplastron, often cause hinging pin shaft to be cut off or the ball joint bearing inner sleeve is broken.And the assembling of each pressing plate and front and back frame hyoplastron all adopts welded type, and maintenance difficulty and repair density are large.
The utility model content
The purpose of this utility model provides the central articulated mounting of a kind of scraper, adopts ball-and-socket hinge style to have the low problem of concentricity of upper and lower hinged pin-and-hole to solve the central articulated mounting of existing scraper.
The utility model adopts following technical scheme: the central articulated mounting of a kind of scraper, comprise cutting with scissors in hyoplastron, the afer bay in upper press cover, lower cover, middle hinge pin axle, the forebay and cut with scissors hyoplastron, double-row conical bearing is equipped with at hinge hyoplastron center in described afer bay, and described upper press cover is connected with lower cover by cutting with scissors hyoplastron in bolt and the described forebay and is connected.
1, the utility model adopts and can bear the double-row conical bearing that radially reaches axial joint load that radial load is the master, and force-bearing situation changes good, and the front/rear frame concentricity is high, compact conformation, and make front/rear frame deflection more flexible.
2, the cooperation of gland with the frame hyoplastron is connected with fastening bolt, safeguards more simple, quick.
3, lubricated good, the anti-outer damage ability of the utility model is strong, maintenance is little.
Description of drawings
Fig. 1 is the structural representation of the central articulated mounting of a kind of scraper.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
The central articulated mounting of a kind of scraper, comprise in upper press cover 1, lower cover 2, middle hinge pin axle 3, the forebay and cut with scissors hyoplastron 4 in hinge hyoplastron 5, the afer bay, double-row conical bearing 6 is equipped with at hinge hyoplastron 4 centers in afer bay, and upper press cover 1 is connected with lower cover respectively and is connected by cutting with scissors hyoplastron 5 in bolt and the forebay.
Claims (1)
1. scraper central authorities articulated mounting, comprise cutting with scissors in hyoplastron, the afer bay in upper press cover, lower cover, middle hinge pin axle, the forebay and cut with scissors hyoplastron, it is characterized in that: cut with scissors hyoplastron (4) center in described afer bay double-row conical bearing (6) is housed, described upper press cover (1) is connected 2 with lower cover) be connected by cutting with scissors hyoplastron (5) in bolt and the described forebay respectively.
