Abstract
The utility model discloses an over-stroke protector for a hoister, which comprises a framework and a lead screw, wherein the lead screw is mounted on the framework and connected with the hoister. One end of the lead screw is connected with an encoder via a gear I and a gear II which are meshed mutually, two stroke switches are installed on the framework, and a moving board is disposed between the two stroke switches and connected with the lead screw via a linear bearing. A moving distance of the moving board can accurately reflect moving positions of the hoister dragging a carrying device via the encoder and a controller, positions of the stroke switches are adjustable and can be set on the rear of set stroke positioning points of the hoister, once a master controller is fail, the hoister runs continuously, the moving board is moved to the stroke switches, actions of stroke switch contact points can be conveyed to the controller outside the hoister via a conducting wire, and then the controller leads the hoister to be off and stopped, thereby effectively avoiding accidents.
Description
Technical field
The utility model relates to a kind of winch, is specially a kind of winch when using over travel, the protector of winch auto-stop.

Summary of the invention
In order to solve the weak point of above-mentioned technology; the utility model provides a kind of over-travel protector for winding engine; this machine comprises frame, be installed on the frame and with winch bonded assembly leading screw, and leading screw one end bonded assembly coder, rack-mounted two travel switches, be arranged between two travel switches and with leading screw bonded assembly shifting board.In case surmount predefined position, shifting board is run into travel switch, winch is out of service, can mis-use breakdown.
The utility model is achieved by the following technical solution: a kind of over-travel protector for winding engine is characterized in that: this machine comprises: frame, leading screw, coder, shifting board, travel switches I and travel switches I I; Described frame comprises base plate, bearing seat I and bearing seat II; Described bearing seat I and bearing seat II are vertically fixed on the base plate, and described leading screw is connected with bearing seat II with bearing seat I with bearing cap shim by bearing, and an end of leading screw is connected with winch, and the other end of leading screw is connected with coder; Described coder is installed in the inboard of bearing seat I by the coder support, and coder is connected with machine controller outward by lead I; The bottom of bearing seat I and bearing seat II inboard is provided with travel switches I and travel switches I I, and travel switches I is connected with machine controller outward by lead II with travel switches I I; Described shifting board is connected with leading screw by screw; The shifting board lower end is provided with adjusting screw(rod), and the contact of the two ends of described adjusting screw(rod) and travel switches I and travel switches I I aligns; The lower end of shifting board is provided with pilot bar, and described pilot bar sliding fit is inserted in the hole of shifting board, and the two ends of pilot bar are fixed on bearing seat I and the bearing seat II, and parallel with leading screw.
Described leading screw is by pitch wheel I and gear II 6-1 and coder.
Described leading screw is the sphere leading screw, and described screw is a linear bearing.
The beneficial effects of the utility model are:
In case 1 winch master controller is malfunctioning, protector is in time worked, and guarantees the work safety of winch.
2, gear transmission structure compactness, it is little to take up room, applied widely.
3, gear transmission accuracy rate height, friction is little, long service life.

Below by drawings and Examples the utility model is described in further details:
Fig. 1 is the utility model structural representation.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the A-A section-drawing of Fig. 1.
Among the figure: 1, base plate, 2, bearing cap shim, 3, bearing seat I, 4, bearing, 5, the coder support, 6, gear I, 6-1 gear II, 7, coder, 8, travel switches I, 9, leading screw, 10, pilot bar, 11, screw, 12, shifting board, 13, travel switches I I, 14, bearing seat II, 15, adjusting screw(rod), 16, lead I, 17, lead II.
The specific embodiment
Shown in Fig. 1,2,3,4: a kind of over-travel protector for winding engine is characterized in that: this machine comprises: frame, leading screw 9, coder 7, shifting board 12, travel switches I 8 and travel switches I I 13; Described frame comprises base plate 1, bearing seat I 3 and bearing seat II 14; Described bearing seat I 3 and bearing seat II 14 are vertically fixed on the base plate 1, and described leading screw 9 is connected with bearing seat II 14 with bearing seat I 3 with bearing cap shim 2 by bearing 4, and an end of leading screw 9 is connected with winch, and the other end of leading screw 9 is connected with coder 7;
Described coder 7 is installed in the inboard of bearing seat I 3 by coder support 5; The bottom of bearing seat I 3 and bearing seat II 14 inboards is provided with travel switches I 8 and travel switches I I 13; Described shifting board 12 is connected with leading screw 9 by screw 11; Shifting board 12 lower ends are provided with adjusting screw(rod) 15, and the contact of the two ends of described adjusting screw(rod) 15 and travel switches I 8 and travel switches I I 13 aligns; The lower end of shifting board 12 is provided with pilot bar 10, and described pilot bar (10) sliding fit is inserted in the hole of shifting board 12, and the two ends of pilot bar 10 are fixed on bearing seat I 3 and the bearing seat II 14, and parallel with leading screw 9.
