Abstract

The utility model provides a scooptram whose rear bodywork swings, comprising a front frame and a rear bodywork. The scooptram is characterized in that a revolving support is arranged at the front end of the rear bodywork; the revolving support comprises an inner ring and an outer ring which are moveably connected; the outer ring is fixedly connected with the rear bodywork; a pendular body is fixedly connected on the inner ring; and the front frame is hinged with the pendular body through an articulating shaft. The scooptram realizes the swinging of the whole rear bodywork through the revolving support; the swinging angle is not limited; the front and rear rear bodyworks can smoothly get across unsmooth roads; the components of a swinging mechanism are low in wear rate and long in service lives; and the safety performance of the whole scooptram is greatly improved.

Description

Aftercarriage swing scoper

Technical field

The utility model relates to a kind of aftercarriage swing scoper, belongs to the down-hole winning equipment.

Background technology

The aftercarriage swing mode of tradition scoper all is the back axle swing, and its structure is generally: by bolted connection swing seat, the swing seat is gone up a hinged swing span, and back axle is set on the swing span on aftercarriage, can only realize that back axle and swing span are around the swing of swing seat.Shortcoming is that the pendulum radius of swing span is limited, the unsettled phenomenon of single wheel occurs through regular meeting on special road conditions; cause part aftercarriage weight to be inclined and be pressed on the swinging gear, the parts wear of swinging gear is big, easily ruptures; service life is short, and therefore the safety performance of car load also is affected.

Summary of the invention

The purpose of this utility model is intended to overcome the deficiency of prior art, provide a kind of swing freely, the high aftercarriage of safety performance swing scoper.

The technical solution of the utility model is as follows: a kind of aftercarriage swing scoper, it comprises forebay, aftercarriage, characteristics are, front end at aftercarriage is provided with the revolution support, interior ring and the outer shroud that comprises flexible connection supported in revolution, outer shroud is captiveed joint with aftercarriage, captive joint pendular body on interior ring, and forebay is hinged by jointed shaft and pendular body.

The utility model supports the swing that realizes whole aftercarriage by revolution, pendulum angle is unrestricted, and the front and back car body can be steadily freely by various concavo-convex ground condition, and the parts wear rate of swinging gear is little, long service life, car load safety performance have raising greatly.

Below in conjunction with drawings and Examples the utility model is at length explained.

Description of drawings

Fig. 1-structural representation of the present utility model;

The birds-eye view of Fig. 2-Fig. 1.

The explanation of accompanying drawing drawing:

1 forebay, 2 pendular bodies, 3 revolutions are supported, 4 aftercarriages, 5 interior rings, 6 outer shrouds, 7 jointed shafts, 8 bolts, 9 bolts.

The specific embodiment

Referring to Fig. 1, Fig. 2, this scoper comprises forebay 1 and aftercarriage 4, front end at aftercarriage 4 is provided with a revolution support 3, revolution support 3 is in the form of annular discs, ring 5 and outer shroud 6 in comprising, interior ring 5 flexibly connects by antifriction-bearing box with outer shroud 6, and outer shroud 6 is fixed on the aftercarriage 4 by bolt 8, by pendular body 2 of bolt 9 captive joints, forebay 1 is hinged with pendular body 2 by middle jointed shaft 7 on interior ring 5.

Forebay 1 can relatively rotate by middle jointed shaft 7 with pendular body 2, turns to about the realization scoper, under the situation of road injustice,, aftercarriage 4 rotates but supporting 3 both sides by revolution, thus the swing of realization aftercarriage.

Claims

1, a kind of aftercarriage swing scoper, it comprises forebay (1), aftercarriage (4), it is characterized in that, front end at aftercarriage (4) is provided with revolution support (3), interior ring (5) and the outer shroud (6) that (3) comprise flexible connection supported in revolution, aftercarriage (4) is captiveed joint with outer shroud (6), goes up captive joint pendular body (2) at interior ring (5), and forebay (1) is hinged by jointed shaft (7) and pendular body (2).
