The specific embodiment
As shown in Figure 1, the arc backplate is installed at the middle part of winch drum 3, and winch drum 3 is separated into two parts, and the effect of arc backplate is to prevent twisted rope.Device to be driven for example twists band machine 2, far-end be provided with pulley 6.Twisted rope 5 (for example, steel rope) is wrapped on the winch drum 3, and the centre portion of twisted rope 5 is fixed on the cylinder.
If twisted rope 5 adopts steel cable to process, just earlier an end steel rope is wrapped on the cylinder, twine to the 3-5 circle, cable wire end is drawn to cylinder continuation rotation enough is fixed on a point place, then the other end is fixed on b point place and can accomplishes wiring.The arc backplate is welded on the cylinder middle part, prevents that side steel rope winding too much is pressed onto the opposite side steel rope, has played the effect of protection, the twisted rope phenomenon can not occur.But hole 7 to arc protective opposite side is then passed in the weld perforate 7 of arc backplate and winch drum 3, steel rope, and attachment point is located in inferior hole.
If adopt two steel ropes as twisted rope 5, then earlier wherein steel cable be wrapped on the cylinder, when twining another root steel rope, extract preceding steel cable out long enough simultaneously, be fixed on a then, 2 of b locate get final product, the steel rope of cylinder side is fixed respectively.
One end of twisted rope 5 is fixed on first attachment point that twists band machine 2 through pulley 6, and (put a), the other end is fixed on second attachment point (some b) of strand band machine 2.And make twisted rope 5 keep certain degree of tension.Point a and some b are positioned at the same side of twisting band machine 2.The position of a, two points of b is confirmed according to the distance that strand band machine moves back and forth.At first confirm a point: make strand band machine place critical spot (being B point limit switch operating position) at one end, then can be selected in strand band machine middle part as a point.The b point is taken at and makes strand band machine be in other end critical spot (being A point limit switch operating position); Away from a point, be in order to reduce a, two points of b lateral pull like this at critical spot pair twist band machine, the lateral pull of the pair twist band machine far away that a, two points of b relative position are got is more little; Preferably; Two ends at strand band machine 2 are the most desirable as a, b point, but basic, as long as can make strand band machine 2 move back and forth distance.
When work, but the winch drive motor 4 of rotating starts 3 rotations of driving winch drum.When strand band machine 2 needs reach, utilize the motor switch invertibility of (not showing among the figure that it can make motor realize rotating), starter motor 4 is just changeing, and strand band machine 2 will move according to arrow G direction among the figure.The side that twisted rope 5 is fixed on a b place is wrapped on the winch drum 3 along the F direction, and the opposite side of twisted rope 5 is twisted band machine 2 through attachment point a and pulls out, oppositely in like manner.
, strand band machine 2 presses halt switch after arriving assigned address; When the switch stop button breaks down and can't stop; Strand band machine 2 can continue to move to the position at the first self-resetting type limit switch 1 (switch A) place; Thereby opening limit switch A cuts off the just commentaries on classics control loop of motor switch, plays the purpose of back-up protection, and does not influence reverse control operation.
Otherwise when starter motor 4 counter-rotatings, strand band machine 2 will move according to the reversing sense of arrow G direction among the figure.Strand band machine 2 leaves limit switch A, and switch A is closed to prepare for motor is just changeing.Oppositely move to the second self-resetting type limit switch (switch B) until strand band machine 2, its principle is identical with switch A, plays the reverse back-up protection effect of moving into strand band machine 2.Shown among the figure that switch A and B are positioned at the two ends end position of strand band machine 2.
Fig. 3 has shown the schematic circuit diagram of the strand band machine control loop that comprises switch A and B, and this control loop comprises just changes control loop, counter-rotating control loop.ZC is positive contactor coil adhesive contactless switch; ZJ is the intermediate relay interlock protection, and FC is counter-rotating contactless coil adhesive contactless switch, and FJ is the relay interlock protection; B1, B2, A1, A2 are respectively B point, the back-up protection of A point limit switch; QA1, QA2 are the rotating start button, and ZJ1, FJ2 are rotating self-insurance point, and AT is a stop button.
When confirming that 36v has electricity, overcurrent relay switch DJ, limit switch A point, limit switch B point, relay interlock protection FJ, intermediate relay interlock protection ZJ are in closure state.Press rotating start button QA1, the ZC coil gets electric positive contactor adhesive, and ZJ1 self-insurance point is closed, and motor 4 is just being transported commentaries on classics, and strand band machine 2 is pressed stop button AT after arriving assigned address, and motor 4 shuts down.If this moment, stop button AT was bad, can't stop motor 4, strand band machine 2 continues to move forward, and when arriving limit switch A position, limit switch A will be opened, and motor 4 shuts down, and realizes one and is just shifting moving process.During reverse moving, press rotating start button QA2, the FC coil gets the adhesive of electric counter-rotating contactless switch, and FJ1 self-insurance point is closed, motor 4 counter-rotating runnings, and strand band machine 2 is pressed stop button AT after arriving assigned address, and motor 4 shuts down.Can't stop motor if stop button AT this moment is bad, strand band machine 2 continues to move backward, and when arriving limit switch B position, limit switch B will be opened, and motor shuts down, and realizes a counter-rotating moving process.After strand band machine 2 reverse moving, leaving just changes limit switch A, is just changeing limit switch A closure and is just changeing ready for motor, and counter-rotating in like manner.
Preferably, foregoing circuit also comprises fuse overcurrent protection RD, overcurrent relay switch DJ.
In another embodiment, can change Starting mode into crawl, i.e. not wiring is put in ZJ1, ZJ2 two self-insurances, pins rotating start button QA1 when just changeing, and motor 4 is just changeing; Pin rotating start button QA2 during counter-rotating, motor 4 counter-rotatings, limit switch A and B can both play the effect of protection.
Fig. 4 has shown the circuit diagram of the control loop of the utility model.It is a reversible electromagnetic starting switch of explosion-proof vacuum.
Through the utility model, only need a people to start just can accomplish and move back and forth operation, save time, reduce investment, reduce fault rate.
The foregoing description is used for the utility model of explaining; Rather than the utility model limited; In the protection domain of the spirit of the utility model and claim,, all fall into the protection domain of the utility model to any modification and the change that the utility model is made.
