Abstract
The utility model discloses a novel swing span of a bowl scraper, including supporting plates and mounting plates equipped on the supporting plates; two supporting plates are respectively provided with bearing sleeves; and the supporting plates and the mounting plates form a frame. The swing span is a double-supporting structure, bears an external force in a uniformly manner, is flexible to swing, has increased swinging strength and prolonged service life, occupies a small space on a scraper body, improves integrated equipment quality of the bowl scraper and is especially suitable for the bowl scraper with a compact volume.
Description
Technical field
The utility model belongs to mechanical fitting manufacturing technology field, relates to a kind of parts that are applied to the scraper of underground mining, is specifically related to the novel swing span of a kind of scraper.
Background technology
Existing scraper swing span is designed to single support pattern, promptly only on the fore-stock of swing span, is provided with a single mandrel, and through this axle swing span is installed on the scraper aftercarriage.This single support pattern makes swing span be equivalent to semi girder, discontinuity equalization, and the stressed axle that concentrates on has influence on complete vehicle quality.Cause often taking place in the use phenomenon of axle cylinder step transition place's fracture, equipment dependability descends, and fault power time and maintenance cost increase, and service efficiency is low, has influenced ordinary production.
The utility model content
In order to overcome the problem that exists in the above-mentioned prior art, the purpose of the utility model provides a kind of novel swing span of scraper of double base form, and stress equalization has solved the stressed axle that concentrates on of swing span and caused the axle problem of fracture easily.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is the novel swing span of a kind of scraper; Comprise support plate and be installed on the installing plate on the support plate; Described support plate is two, is respectively arranged with bearing holder (housing, cover) on these two support plates, and described support plate and installing plate constitute a framework.
Be installed on two coaxial settings of the bearing holder (housing, cover) on the support plate.
The utility model swing span adopts double supporting structure, has overcome swing span and has been installed on the semi girder form that forms on the scraper aftercarriage, can effectively guarantee the reliability of mechanism; Stressed even, simple in structure, stable working; Increase the intensity of swing span simultaneously, improved the application life of swing span, practiced thrift the installing space on the car body; Improve scraper complete machine quality, be applicable to the scraper of compact conformation.
Description of drawings
Fig. 1 is the structural representation of existing scraper swing span.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of the utility model scraper swing span.
Fig. 4 is the vertical view of Fig. 3.
Among the figure, 1. support plate, 2. axle, 3. installing plate, 4. clutch shaft bearing cover, 5. second bearing holder (housing, cover).
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The structure of existing scraper swing span, as depicted in figs. 1 and 2, comprise support plate 1, axle 2 and four installing plates 3 are installed on the support plate 1; During use, axle 2 is penetrated in the connecting hole on the scraper aftercarriage, through nut axle 2 is fixed on the scraper aftercarriage, thereby swing span is installed on the scraper.But the swing span of this structure is single support pattern when being installed on the scraper aftercarriage; Make swing span be equivalent to semi girder, cause the swing span discontinuity equalization, the stressed axle 2 that concentrates on; The phenomenon of axle cylinder step transition place's fracture often takes place in the use; Influence complete vehicle quality, equipment dependability descends, and has influenced ordinary production.
In order to overcome the problem that exists in the above-mentioned prior art, the utility model provides a kind of double base swing span, and stress equalization improves complete vehicle quality and equipment dependability.The structure of this double base swing span like Fig. 3 and shown in Figure 4, comprises that being arranged with four installing plates, 3, two support plates 1 in parallel between 1, two support plate 1 of two support plates that laterally arranges is connected through these four installing plates 3; Two support plates 1 and four installing plates 3 constitute a framework.
Wherein on a support plate 1 clutch shaft bearing cover 4 is installed, second bearing holder (housing, cover) 5 is installed on another piece support plate 1; Clutch shaft bearing cover 4 is with the 5 coaxial settings of second bearing holder (housing, cover) and be connected with support plate 1 through bearing respectively.
When the utility model swing span is installed on the scraper aftercarriage, the bearing holder (housing, cover) at swing span two ends is installed in respectively on the aftercarriage, makes bearing holder (housing, cover) stretch out the part of support plate 1 and cooperate installation with copper sheathing on the aftercarriage.
The utility model swing span adopts double supporting structure, not only can guarantee the flexibility of the stressed all even swings of swing span, has increased swing span intensity, has prolonged the application life of swing span; And practiced thrift the installing space on the car body, improved scraper complete machine quality; Be particularly useful for the quite compact scraper of space structures.
Claims (2)
1. novel swing span of scraper; Comprise support plate (1) and be installed on the installing plate (3) on the support plate (1), it is characterized in that described support plate (1) is two; Be respectively arranged with bearing holder (housing, cover) on these two support plates (1), described support plate (1) constitutes a framework with installing plate (3).
