The safeguard of the utility model adopts the unique structure of the linkage of the anti-falling protection actions for cable breaking in leveling operation and the operating actions of the discharge door, so the utility model has the advantages simple and reasonable structure, sensitive and accurate action and safety; therefore, the defect of unsafety caused by the easy misoperation in the prior art is effectively overcome.
Description
The utility model relates to a kind of safety guard that is used for building hoist, specifically refers to a kind of disconnected cable falling-proof safety device of flat bed operation that has when derrick formula building hoist flat bed is operated.
The frame type hoist of construction trade use at present; of a great variety; but generally all do not possess the disconnected cable anti-falling protection function when the flat bed operation is arranged; though also there is the construction elevator device of only a few that the simple manual operation anti-fall device is arranged; as adopt the bolt-type anti-fall device; inject slow movement, the bright position of operator is unreasonable and easily produces deficiency such as misoperation but exist owing to its structure is extremely unreasonable to sell directly to households; more can't make flat bed anti-falling protection and elevator discharge door action interlocking, thereby the anti-falling protection function also can't reach its flat bed operation the time.
The purpose of this utility model just is to provide a kind of later-model flat bed operation disconnected cable falling-proof safety device; has the unique texture of anti-fall action of flat bed and discharge door operation interlocking by it; make itself and the double shielding of existing disconnected cable fall-preventing protection device realization to building hoist; and have simple and reasonable, the accurate sensitive and safe and reliable advantage of action, because of being easy to error, operation causes unsafe deficiency thereby overcome prior art effectively.
The purpose of this utility model realizes in the following manner: the disconnected cable falling-proof safety device of a kind of flat bed operation; mainly be by cage; guide rail; discharge door and flat bed fall-preventing protection device are formed; it is characterized in that the flat bed fall-preventing protection device is arranged on the discharge door below and guide rail joint of cage; the flat bed fall-preventing protection device is mainly by hanger of heavy tail; boss; side plate; connecting shaft; briquetting; long shaft rod; depression bar; retaining lock and dowel bar are formed; wherein hanger of heavy tail is fixed on the connecting shaft that is connected as a single entity with long shaft rod by key; its both sides activity is fixed with and is provided with boss and retaining lock and by connecting the side plate that piece links to each other; one end of long shaft rod is fixed with dowel bar; and by on the support that locating plate is fixed on cage is connected; dowel bar matches with the depression bar that is positioned on the support by double-screw bolt and nut on it, is respectively arranged with the briquetting that depression bar is rotated to an angle around double-screw bolt at the two ends, discharge door bottom of cage.
Adopt the disconnected cable falling-proof safety device of flat bed operation of the present utility model; owing to adopted particular structure with the disconnected cable anti-falling protection action of flat bed and the interlock of its discharge door operational motion; and make this device realize double shielding to building hoist with existing disconnected cable fall-preventing protection device; and have simple and reasonable, action is accurately sensitive and safe and reliable advantage; causing unsafe deficiency thereby overcome prior art effectively because of operating easy error, is that a kind of comparatively desirable building operation is operated disconnected cable falling-proof safety device with the flat bed of elevator.
Description of drawings.
Fig. 1 is that device has elevator structure scheme drawing of the present utility model;
Fig. 2 is the disconnected cable falling-proof safety device structural representation of flat bed operation;
Fig. 3 is the view of overlooking of Fig. 2.
Wherein: the heavy-tailed hook of 1-, the 2-boss, the 3-side plate, the 4-connecting shaft, 5-connects piece, the 6-briquetting, the 7-long shaft rod, the 8-locating plate, the 9-double-screw bolt, the 10-depression bar, the 11-nut, the 12-key, 13-keeps off lock, 14-force-bearing piece, 15-guide rail, 16-discharge door, 17-dowel bar, 18-cage.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a kind of embodiment of the present utility model.As shown in the figure; the disconnected cable falling-proof safety device of flat bed operation of the present utility model; mainly by cage (18); guide rail (15); discharge door (16) and flat bed fall-preventing protection device are formed; this flat bed fall-preventing protection device is arranged on discharge door (16) below and guide rail (15) joint of cage (18); the flat bed fall-preventing protection device mainly is by hanger of heavy tail (1); boss (2); side plate (3); connecting shaft (4); briquetting (6); long shaft rod (7); depression bar (10); retaining lock (13) and dowel bar (17) are formed; wherein hanger of heavy tail (1) is to be fixed on the connecting shaft (4) that is connected as a single entity with long shaft rod (7) by key (12); hanger of heavy tail can rotate with connecting shaft by the effect of key; its front end can insert under the effect of afterbody deadweight in the guide rail and by force-bearing piece (14) braking (this moment, discharge door was an opening); be fixed with the side plate (3) that is provided with boss (2) and keeps off lock (13) and link to each other by company's piece (5) in the activity of the both sides of hanger of heavy tail; connecting shaft (4) can rotate in side plate (3) hole; long shaft rod (7) is connected as a single entity by coupling device with connecting shaft (4); the other end at long shaft rod is fixed with dowel bar (17); and be fixed on the support that is connected with cage (18) by locating plate (8); dowel bar on it (17) matches with the depression bar (10) that is positioned on the support by double-screw bolt (9) and nut (11); be that above-mentioned dowel bar can be under the effect of depression bar up-and-down movement; drive long shaft rod and connecting rod and do the rotation of certain angle, be respectively arranged with the briquetting (6) that depression bar (10) is rotated to an angle around double-screw bolt (9) at discharge door (16) two ends, bottom of cage (18).
In use, when building construction hoist normally moves, the discharge door of its cage is in (pressing down) state of closing that prevents that material skids off in it, the briquetting at its two ends, discharge door bottom is by the effect of depression bar and dowel bar at this moment, make the front end getaway of hanger of heavy tail, and make cage rise smoothly or to descend; When cage reaches a certain working surfaces; open discharge door (rising); its upper holder block breaks away from depression bar; this moment, hanger of heavy tail rotated to an angle under the effect of its afterbody deadweight; its front end is inserted in the guide rail; and under the effect of its force-bearing piece, play tenesmus when preventing the disconnected cable of cage when cable (disconnected, cage only has a small amount of tenesmus between two force-bearing pieces in guide rail), thereby finish the purpose of the disconnected cable falling-proof safety of flat bed operation of the present utility model.Use the disconnected cable falling-proof safety device of flat bed operation of the present utility model, all can play certain safety guard-safeguard effect in the operating various abnomal conditions of elevator, and can not cause any unnecessary damage elevator.
