Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1: referring to fig. 1-2, a safety fixing device for a movable beam of a hydraulic machine comprises a base 1 and a fixing rod 2, wherein the base 1 is welded and fixed on an upper beam, and the upper end of the fixing rod 2 is welded and fixed on the movable beam; a locking device 3 is arranged in the base 1, so that the bottom end of the fixed rod 2 extends into the base 1 and is movably connected with the locking device 3.
Example 2: on the basis of embodiment 1, the locking device 3 comprises a frustum, the inner sides of the frustum are respectively provided with hole grooves which are mutually communicated, in the embodiment, four hole grooves are mutually communicated, the fixing rod 2 is positioned in the middle of the mutual communication of the hole grooves, the outer side of the frustum is in sliding connection with the inner wall of the base 1, a first oil cavity 4 and a second oil cavity 5 are formed between the locking device 3 and the inner side of the base 1, and a first oil port 8 and a second oil port 9 are arranged on the side wall of the base 1, so that the first oil port 8 is communicated with the first oil cavity 4; and a second oil port 9 is communicated with the second oil cavity 5.
Example 3: on the basis of embodiment 2, a locking ball 6 is provided in each hole groove, and the locking ball 6 can move laterally left and right in the hole groove, for example, when moving rightwards, one side of the locking ball 6 is moved towards the central axis along with the locking device, and the fixing rod 2 is clamped, for example, when moving leftwards, one side of the locking ball 6 is moved away from the fixing rod 2 along with the locking device towards the inclined wall of the hole groove.
Example 4: on the basis of embodiment 2, the upper end in the base 1 is provided with a limit end 7 for limiting when the frustum slides and ascends, when the first oil port 8 is filled with oil, when the oil enters the first oil cavity 4 through the first oil port 8, the locking device ascends in the base 1 due to the condition of bottom oil pressure, each locking ball 6 in the locking device approaches to the central axis in the ascending process of the locking device, the fixed rod 2 is clamped, at the moment, the system is suddenly powered off or the operation personnel changes the mould, and the movable cross beam does not suddenly fall.
