Abstract
The utility model discloses a roadheader boosting mechanism for roadway climbing. The mechanism comprises a connecting frame, an adjusting device, a crossbeam, support legs and cylinders. The adjusting device is arranged between the connecting frame and the crossbeam. Two sets of the support legs and the cylinders are respectively symmetrically arranged in the two ends of the crossbeam. The cylinders are fixed on the crossbeam and the end of each cylinder lever is fixedly connected with the end of each support leg. The support legs are movably connected with the crossbeam. The utility model has the benefits of simple structure and convenient use, which can normally work when the roadheader is arranged at the angle more than or equal to 18 degrees and less than 24 degrees in the roadway and is unaffected by the environmental limit.
Description
Technical field
The utility model discloses a kind of development machine boosting mechanism that is used for tunnel climbing work.
Background technology
At present, the inclination angle, tunnel of domestic development machine operate as normal will occur gliding for the tunnelling machine greater than this angle mostly less than ± 18 °, can not normally tunnel, and working environment is subjected to certain restriction, influences normal job schedule.
Summary of the invention
The purpose of this utility model is to provide the development machine boosting mechanism to solve the shortcoming that above-mentioned technology inter-road road inclination can not normally be climbed and advance greater than 18 ° of development machines.
The technical scheme that realizes the utility model purpose is as follows:
The development machine boosting mechanism, this mechanism comprises link, adjusting device, crossbeam, supporting leg and cylinder, adjusting device is located between link and the crossbeam, supporting leg and cylinder have two groups respectively symmetry be located at the crossbeam two ends, cylinder is fixed on the crossbeam, its cylinder boom end is fixedlyed connected with the supporting leg end, and supporting leg and crossbeam flexibly connect.
Described adjusting device is formed with the adjustment pipe by adjusting screw mandrel, adjust screw mandrel and be divided into adjustment screw mandrel and following adjustment screw mandrel, last adjustment screw mandrel is engaged in adjustment pipe two ends with the following wire rod thread of adjusting, last adjustment screw mandrel is fixed on the link, following adjustment screw mandrel is fixed on the crossbeam, adjusts pipe and is provided with rotating handle.
Described crossbeam two ends are fixed with the crossbeam arm by connecting pin, and described supporting leg is movably connected on crossbeam arm end.
Useful benefit of the present utility model is simple in structure, and is easy to use, it can make development machine the tunnel angle for more than or equal to 18 ° can operate as normal during less than 24 °, be not subjected to environmental limitations.
