Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and a preferred embodiment.

Referring to fig. 1, a hanging basket 1 is hung below two claw heads 3 through a steel wire rope 2, the steel wire rope 2 bypasses a roller at the top of the claw heads 3 and is downwards connected with a lifter along the claw heads, the steel wire rope 2 is released through a winch to drive the hanging basket 1 to descend to a working position, and after cleaning is completed, the steel wire rope 2 is wound through a winch to drive the hanging basket 1 to ascend. A hanging basket upper limiting device is respectively arranged below the roller at the top of each horn head 3.

Referring to fig. 2 and 3, the basket upper limit device of the present embodiment includes a pressure plate 10, an upper limit bracket 20, a first travel switch 30, and a second travel switch 40.

The clamp plate 10 has two, and two clamp plates grasp the wire rope 2 that is located between goat's horn head 3 and the hanging flower basket 1 to through the screw that passes the clamp plate and wire rope 2 fastening connection, thereby make clamp plate 10 can follow wire rope 2 and do ascending or descending motion.

The heads of the first travel switch 30 and the second travel switch 40 are respectively and fixedly arranged at two sides of the claw head 3 outwards through screws, the first travel switch 30 and the second travel switch 40 are both in the prior art, and in the embodiment, the two travel switches are preferably OsiSense XC Schneider adjustable thermoplastic roller rocker type. The first travel switch 30 and the second travel switch 40 are controlled by a wire and a hanging basket lifting motor in an interlocking way, when the first travel switch 30 is triggered, the hanging basket lifting motor stops running, and the hanging basket stops rising at the upper limit position; when the second travel switch 40 is triggered, the basket lifting motor stops running and the motor is braked, so that the basket stops lifting at the extreme position immediately.

Go up spacing support 20 and include a flat rectangular support body that extends along the horizontal direction, the one end middle part of support body outwards stretches out along the face and forms the support arm, is equipped with hollow pipe 21 on the support arm, sets up the square hole that supplies wire rope 2 to pass on the rectangular support body, and sets up logical groove in the outside of square hole, makes things convenient for wire rope 2 to get into and limits support 20. The two sides of the bracket body are respectively connected with a first detection plate 22 and a second detection plate 23, the first detection plate 22 is L-shaped, the horizontal part of the first detection plate is fixed on the upper side surface of the front end of the rectangular bracket body, and the vertical part of the first detection plate is bent upwards. The second detection plate 23 is flat and fixed in parallel to the upper side of the rectangular bracket body, and the upper side of the horizontal part of the first detection plate 22 is flush with the top surface of the second detection plate 23.

Through holes are correspondingly formed in two side plates below the roller at the top of the horn head, and the upper limiting bracket 20 is rotatably connected with the horn head 3 through a screw 24 penetrating through a hollow circular tube 21 and the through hole of the horn head.

The utility model discloses a theory of operation is:

the upper limit of the hanging basket is mainly realized by the circular motion of the upper limit bracket 20 to contact with the travel switch, so that the travel switch is driven to act.

In normal operation, the first travel switch 30 and the second travel switch 40 are not in contact with the upper limit bracket 20, and no action signal is given.

When the hanging basket 1 ascends, the pressure plate 10 is driven by the steel wire rope 2 to ascend, when the hanging basket 1 reaches a set height, namely an upper limit position, the pressure plate 10 lifts the upper limit bracket 20, the upper limit bracket 20 rotates upwards around the screw rod 24, the first detection plate 22 on the upper limit bracket 20 contacts the first travel switch 30 firstly, the hanging basket 1 is prompted to reach the upper limit position, the lifting motor stops running, and the hanging basket stops at the upper limit position.

Normally, the hanging basket 1 stops at the upper limit position, but when the lifting speed of the hanging basket 1 is too high or the first travel switch 30 fails, the hanging basket 1 can still continuously lift, at this time, the second detection plate 23 on the upper limit bracket 20 can be contacted with the second travel switch 40, the position of the second travel switch 40 is the lifting limit position of the hanging basket 1, the second travel switch 40 is similar to an emergency stop button, so that the lifting motor is locked, the hanging basket 1 immediately stops lifting, and at this time, the hanging basket 1 is only allowed to fall but cannot lift.

When the basket 1 descends, the lower limit bracket 20 rotates downwards around the screw 24 due to self weight, and the first travel switch 30 and the second travel switch 40 are released.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and the improvements and modifications are also within the protection scope of the present invention.
