Abstract
The lifting mechanism of this drill carriage, comprises hinged support cylinder, rear support beam and the handrail being installed on upper end, drill carriage chassis of tail end; Hinged front support beam and the workplatform being installed on rear support back end of tail end, the piston rod head end of support cylinder is hinged to be installed on rear support beam, the top of handrail is hinged to be installed on front support beam, the left and right sides, workplatform lower end respectively with the top of front support beam and the hinged installation of piston rod head end of cross cylinder, the tail end of cross cylinder is hinged to be installed on front support beam.By main support cylinder, rear support beam is boosted, under the effect of handrail, front support beam rises thereupon, by cross cylinder, the workplatform other end is supported simultaneously, keep workplatform level, along with the continuous propelling of support cylinder, the continuous rise of rear support beam, front support beam also constantly rises, and workplatform constantly rises, and keeps level.Prevent from working during lifting flat run-off the straight, improve safety.
Description
Technical field
The utility model relates to coal mine machinery technical field, is specifically related to a kind of lifting mechanism of drill carriage.
Background technology
Supporting in current colliery tunnel support particularly in tall and big tunnel generally adopts scaffolding form, need manually to build, waste of manpower, material resources, also there is potential safety hazard, need one can pulsation-free lifting mechanism, and can remain that platform is parallel, traditional lifting mechanism be when running into acclive tunnel, will run-off the straight during lifting, there is potential safety hazard, and workplatform is also with degree of dip, workman cannot work.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of platform remains level drill carriage lifting mechanism when being elevated.
The utility model overcomes the technical scheme that its technical matters adopts:
The lifting mechanism of this drill carriage, comprises hinged support cylinder, rear support beam and the handrail being installed on upper end, drill carriage chassis of tail end; Hinged front support beam and the workplatform being installed on rear support back end of tail end, the piston rod head end of described support cylinder is hinged to be installed on rear support beam, the top of described handrail is hinged to be installed on front support beam, the left and right sides, described workplatform lower end respectively with the top of front support beam and the hinged installation of piston rod head end of cross cylinder, the tail end of described cross cylinder is hinged to be installed on front support beam.
The beneficial effects of the utility model are: boosted by rear support beam by main support cylinder, under the effect of handrail, front support beam rises thereupon, by cross cylinder, the workplatform other end is supported simultaneously, keep workplatform level, along with the continuous propelling of support cylinder, the continuous rise of rear support beam, front support beam also constantly rises, and workplatform constantly rises, and keeps level.Prevent from working during lifting flat run-off the straight, improve safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1. workplatform 2. front support beam 3. handrail 4. chassis 5. cross cylinder 6. rear support beam 7. support cylinder.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
The lifting mechanism of this drill carriage, comprises hinged support cylinder 7, rear support beam 6 and the handrail 4 being installed on upper end, drill carriage chassis 4 of tail end; Hinged front support beam 2 and the workplatform 1 being installed on rear support beam 6 top of tail end, the piston rod head end of support cylinder 7 is hinged to be installed on rear support beam 6, the top of handrail 3 is hinged to be installed on front support beam 2, the left and right sides, workplatform 1 lower end respectively with the top of front support beam 2 and the hinged installation of piston rod head end of cross cylinder 5, the tail end of cross cylinder 5 is hinged to be installed on front support beam 2.By main support cylinder 7, rear support beam 6 is boosted, under the effect of handrail 3, front support beam 2 rises thereupon, supported by cross cylinder 5 pairs of workplatform 1 other ends simultaneously, keep workplatform 1 level, along with the continuous propelling of support cylinder 7, the continuous rise of rear support beam 6, front support beam 2 also constantly rises, and workplatform 1 constantly rises, and keeps level.When preventing from being elevated, workplatform 1 run-off the straight, improves safety.
