Windproof Earth Anchor
Feb 01, 2023| Windproof earth anchor:
The utility model belongs to the installation technical field of windproof ground earth anchor for door engine, in particular relates to a windproof ground earth anchor for door engine.
Background technology:The existing windproof ground earth anchors are mainly threaded rotary plunger type or non-threaded plunger type, and the non-threaded plunger type lock is mainly used for the anchoring of small door engines. Large portal crane is mainly locked with threaded rotary plunger type. When the portal crane needs anchor, manually rotate the ground anchor shaft with threaded in the middle and drop it into the ground locking slot to realize the axial anchoring of the portal crane. When the portal crane needs to move along the axial direction, rotate the ground anchor shaft with thread in the middle and pull it out of the ground anchoring groove manually. Because the door crane is usually located outdoors, the working environment is harsh, and the size of the ground anchor shaft with thread in the middle is large, the thread corrosion often occurs, the ground anchor shaft is stuck, and the manual rotation is difficult. In view of the technical problems existing in the background technology, the windproof ground earth anchor of the door engine provided by the utility model can be either electrically powered or manually anchored. Normal operation using electric anchoring, simple operation, can save manpower. When the electric drive system failure, can use manual drive, high safety factor. In order to solve the above technical problems, the utility model adopts the following technical scheme to realize: The utility model discloses a windproof ground earth anchor for door machine, including an anchoring shaft, the anchoring shaft is arranged in the mounting seat, and the lower end of the anchoring shaft runs through the mounting seat, the anchoring shaft is threaded with the gear nut, the gear nut meshes with the first gear, the first spur gear meshes with the second spur gear, the second spur gear is coaxial connected with the first bevel gear meshes with the second bevel gear, The second bevel gear is driven by the hand wheel to rotate; The second spur gear is driven by a driving motor. In the preferred scheme, a coupling and a clutch are arranged between the driving motor and the second spur gear, and the clutch is used to connect the output shaft of the driving motor with the coupling
