Abstract
The invention discloses a stage hoist which comprises a winding drum with rotating axles arranged at the both ends and rotatably erected on a stand, wherein the winding drum is driven by a motor through a speed reducer and wound with a steel wire rope, a hanging hook is hung on the steel wire rope, ratchet wheels are respectively and fixedly connected on flanges at the both ends of the winding drum, two linkage ratchets which are used by being matched with the two ratchet wheels are arranged on the flanges at the both ends of the winding drum, the two ratchets are coaxial, and ratchet shafts can be rotatably arranged on the stand and driven by motors fixedly connected at the shaft ends and are locked. The invention has the advantages that the heavy objects can be safely hoisted and conveniently hung in the place to stay, and an electric hoisting mechanism with safe and convenient use is provided for the stage; and since the ratchet wheels are only installed on the flanges of the winding drum and braked by the ratchets, the stage hoist is simple and does not have damage to the steel wire rope.
Description
Technical field:
The present invention relates to a kind of electric winch, especially can hang the stage hoist of weight safely.
Background technology:
At present, known winch hangs the people that must not stand under the thing, light of stage curtains etc. are raised to behind the certain altitude by the human suspender belt weight to be hung by the stage cucurbit and fix, but this can not meet requirements hoists and fixingly at an arbitrary position hang tens of tons the lifting requirement of electronic curtain of large-scale gymnasium of weighing.External stage hoist adopts wire rope braking device (be similar in the upper end steel rope is clamped) that steel rope is had damage.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of stage hoist, can safely weight be lifted by crane the position of needs, and can easily weight safety be hung, the people can be worked under weight.
Technical solution problem of the present invention adopts following technical scheme:
Stage hoist, comprise: the two ends rotating shaft is set up in the reel on the frame rotationally, this reel is driven by reductor by electrical motor, on reel, be wound with steel rope and this wire rope suspensioning has suspension hook, on the flange at described reel two ends, be fixedly connected with ratchet respectively, and setting and described two ratchets ratchet of two interlocks of cooperating respectively, the coaxial and pawl axis of two ratchets is arranged on the described frame rotationally, and the motor driven that described pawl axis is connected firmly by its axle head is rotated and locking.
Rotating shaft one end of described reel is arranged on the described frame by bearing seat, and the other end is arranged on the frame by the bearing seat that is mounted with the overload device.
Described electrical motor is the adjustable frequency motor of tep reel formula drg, coder.
Input end at described retarder is provided with second electromagnetic disc type brake.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Stage hoist of the present invention, on the flange at reel two ends, be fixedly connected with ratchet, and on frame, be provided with coaxial respectively with the ratchet of two ratchet cooperatings, when the suspension hook suspension heavy weight arrives desired height, ratchet locking ratchet in place, and ratchet is by the braking of the motor of its axle head, and this moment, steel rope was equivalent to be suspended on the fixture, with respect in the prior art only for the motor braking reel, safer; And this mechanism is simple, can not produce any damage to steel rope.
One end of reel is arranged on the frame by the bearing seat that is mounted with the overload device, the phenomenon of the suspension heavy weight that can not occur overloading.
Electrical motor of the present invention is the adjustable frequency motor of tep reel formula drg, coder; And the input end at retarder is provided with second electromagnetic disc type brake, has more strengthened the safety of winch fixed point suspension heavy weight.
Description of drawings:
Fig. 1 is a main TV structure scheme drawing of the present invention; Fig. 2 is the left view of Fig. 1; Fig. 3 is the birds-eye view of Fig. 1.
Number in the figure: 1 electrical motor, 2 retarders, 3 reels, 4 bearing seats, 5 frames, 6 steel ropes, 7 suspension hooks, 8 ratchets, 9 ratchets, 10 pawl axis, 11 motors, 12 are mounted with the bearing seat of overload device, 13 second electromagnetic disc type brakes.
Below pass through the specific embodiment, and the invention will be further described in conjunction with the accompanying drawings.
The specific embodiment, non-limiting examples is as described below:
Embodiment: in conjunction with Fig. 1-3, the present embodiment stage hoist comprises: the adjustable frequency motor 1 of tep reel formula drg, coder, retarder 2, major diameter reel 3, one end of reel rotating shaft is set up on the frame 5 with bearing seat 4, the other end of reel rotating shaft is set up on the frame 5 with the bearing seat 12 that is mounted with the overload device, stops overload suspention phenomenon.On reel, be wound with steel rope 6 and this wire rope suspensioning has suspension hook 7, on the flange at reel two ends, be fixedly connected with ratchet 8 respectively, and the ratchet 9 of two interlocks of setting and described two ratchets difference cooperating, coaxial and the pawl axis 10 of two ratchets is arranged on the frame 5 rotationally, and the motor 11 that pawl axis is connected firmly by its axle head drives and rotates and locking.
In specifically being provided with, the safety factor of suspension hook, steel rope, reel, click is all greater than ten, and steel rope is two independently left and right sides spinning ropes, even one disconnected, another root also can be with the weight safe landing.
During work, electrical motor 1 drives reel 3 rotations by retarder 2 deceleration force amplifiers, twine or discharge steel rope 6 and realize that suspension hook 7 hangs about the thing, when weight arrives desired height, the plate disc brake that signal control is built in electrical motor discharges, weight is supported in the air, motor 11 drives pawl axis 10 and rotates and make the ratchet ratchet that blocks in place, ratchet signal control electrical motor in place is rotating belt movable reel and ratchet revolution at a slow speed, when ratchet blocks ratchet fully, the resisting moment that drives frequency converter strengthens, the explanation pawl ratchet is stuck when reaching setting value, and motor power is cut off automatically, the pawl axis of motor locking simultaneously, reel has guaranteed to allow the people work under weight because of the fixedly point of suspension of click locking becoming steel rope at this moment; If when needing downward modulation weight suspention height, starter motor drives pawl axis and rotates, make the ratchet rotation break away from ratchet, the electrical motor revolution drives reel and discharges steel rope to desired height, repeats above-mentioned lock program again and gets final product; Certainly, the in place of ratchet also can be by artificial realization, the also mode that promptly adopts ratchet to radially slide along ratchet, the cooperation that realizes pawl ratchet with separate.
Shown in Figure 3, in the concrete configuration, second electromagnetic disc type brake 13 can be set at the input end of retarder 2, in conjunction with the built-in drg of electrical motor, can strengthen intensity to the reel locking, improve safety; In addition, an end of reel rotating shaft is set up on the frame 5 with the bearing seat 12 that is mounted with the overload device, and the warning prompting is to stop the overload suspention during overload.
