Abstract
The utility model discloses a safe startup system for a skid loader, belonging to a safe system and aiming to provide a safe system for a skid loader capable of preventing misoperation. The safe startup system for the skid loader comprises a brake switch, a big-arm lock switch and a bucket lock switch; a seat pressure switch (1) is connected with coils of a relay (3) by a safety belt switch (2); one end of the switch of the relay (3) is connected with the input end of a double safety rod switch (4) while the other end is arranged between the seat pressure switch (1) and the safety belt switch (2); one output end of the double safety rod switch (4) is connected with the brake switch (5) while the other output end is respectively connected with the big-arm lock switch (6) and the bucket lock switch (7); and the seat pressure switch (1) and the other input end of the double safety rod switch (4) are connected with a power. The whole vehicle in the utility model can run and work after plugging the safety belt, so the safety of the operators is well guaranteed.
Description
Technical field: the utility model relates to a kind of security system, relates in particular to a kind of sliding loader secure startup system.
Background technology: sliding loader belongs to heavy engineering machinery, in case misoperation very likely causes major accident, so its safety especially seems important.Yet present sliding loader does not have the safety precautions device mostly, and operator's safety can not get ensureing.
Summary of the invention: to the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of sliding loader secure startup system that can prevent maloperation.
To achieve these goals, the utility model adopts following technical scheme: it comprises brake switch, big arm lock-switch and scraper bowl lock-switch; The output of seating pressure switch is connected with the coil of relay through seat belt switch; Switch one end of relay is connected with the input of duplex safety pole switch, the other end is connected between seating pressure switch and the seat belt switch; An output of duplex safety pole switch is connected with brake switch, another output is connected with the scraper bowl lock-switch with big arm lock-switch respectively, and another input of the input of seating pressure switch and duplex safety pole switch is connected with power supply; Relay is that normally closed relay, seat belt switch are the normally closed type switch.
With prior art relatively, the utility model has been owing to adopted technique scheme, therefore has only after plugging safety belt car load could walk and operation; Otherwise car load can only be walked, and swing arm and scraper bowl can not carry out operation, thereby makes operating personnel's safety obtain better guarantees.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: seating pressure switch 1 seat belt switch 2 relays 3 duplex safety pole switches 4 brake switches 5 big arm lock-switch 6 scraper bowl lock-switchs 7
The specific embodiment: the utility model is described further below in conjunction with accompanying drawing and concrete embodiment:
As shown in Figure 1: the output of seating pressure switch 1 is connected with the coil of relay 3 through seat belt switch 2; The output switching terminal of relay 3 is connected with the input of duplex safety pole switch 4, the switch input terminal of this relay is connected between seating pressure switch 1 and the seat belt switch 2, and an output of duplex safety pole switch 4 is connected with brake switch 5, another output of this duplex safety pole switch is connected with scraper bowl lock-switch 7 with big arm lock-switch 6 respectively; Another input of the input of seating pressure switch 1 and duplex safety pole switch 4 is connected with power supply.Relay 3 is a normally closed relay, and its switch was in a position when its switch was in b position, energising during no power; Seat belt switch 2 is the normally closed type switch, and 2 pass disconnections left by safety belt when plugging safety belt.
Operating principle: ato unit, car load power connection; When operating personnel were sitting on the seat, seating pressure switch 1 was connected.If do not plug in safety belt, the coil of relay 3 gets electronic work, and its switch switches to a position and is in off-state from the b position; When plugging safety belt, seat belt switch 2 breaks off, and the coil blackout of relay 3, its switch switch to the b position from a position and be in on-state; Put down safety pole, duplex safety pole switch 4 is connected.
If do not plug safety belt, relay 3 is off-states.Safety pole puts down, and has only brake switch 5 energisings, and big arm lock-switch 6, scraper bowl lock-switch 7 all are off-states; If safety pole does not put down, brake switch 5, swing arm lock 6 and scraper bowl lock 7 all are off-states.Also promptly do not plug safety belt, even if put down safety pole, the car load braking is removed, and can walk, but swing arm and scraper bowl has no action.
When plugging safety belt, relay 3 is "on" positions.Safety pole puts down, and safety pole switch 4 is connected, brake switch 5, big arm lock-switch 6 and scraper bowl lock-switch 7 all electric, car load could be walked and carried out various operations.
