Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Fig. 1 is please referred to, the present invention provides a kind of elevator of detectable balance, is had in elevator for carrying object
Lifting part 100, referring to figure 2., the lifting part 100 includes:
One lifting frame 150 and the driving device (not shown) for driving elevator to operate, specifically, lifting frame
150 generally stereo hollow columns, in the present embodiment, lifting part 100 is a rectangular-shape, on each side of cuboid
A piece frame column 151 is set, 12 frame columns 151 are at least set, to constitute lifting frame 150, in the present embodiment in order to
Increase the stability of lifting frame 150, is provided with 16 frame columns 151；
It further include at least a pair of pulley assembly 120 being symmetrically fixed on the lifting frame 150, pulley assembly 120 wraps
Two belt fixing axles 121 are included, 150 top of lifting frame, a frame column 151 against top, the lifting unit are located at
The lifting of part 100 realized by sliding of the belt in the belt fixing axle 121, be provided in the present embodiment two pairs about
The symmetrical belt fixing axle 121 of 150 axis of lifting frame；
It further include a lever 111, every one end of lever 111 respectively corresponds to an affixed belt fixing axle 121, but the two
Symmetrically, two belt fixing axles 121 can be located on same frame column 151 belt fixing axle 121, can also distinguish position
In on different frame columns 151, it is only necessary to guarantee that two belt fixing axles 121 are symmetrical.
Referring to figure 3. with Fig. 4, lever fixation kit 112, each lever are all provided on the both ends of lever 111 and center of gravity
Fixation kit 112 includes the lever seat 1121, lever seat pin shaft 1122, snap-gauge 1123 with U-shaped oral area, wherein lever 111 with
And circular hole 114 corresponding with lever seat pin shaft 1122 is offered on lever seat 1121, lever 111 is located at the U-shaped of lever seat 1121
In notch, and correspond to each other respective circular hole 114, lever seat pin shaft 1122 passes through the circular hole 114 of the two, so that lever 111
Hinged relationship is formed with lever seat 1121, lever seat pin shaft 1122 is the rotary shaft of lever 111.Lever seat pin shaft in order to prevent
1122 itself rotate, then are arranged in the notch of a snap-gauge 1123 insertion 1122 side of lever seat pin shaft, which is located at thick stick
1121 outside of pole socket, snap-gauge 1123 can prevent lever seat pin shaft 1122 itself from occurring around axial rotation.
The lever fixation kit 112 of 111 center of gravity of lever is fixed on frame column 151, but the fixed group of the lever at both ends
Part 112 is then fixedly connected by pull rod 113 with corresponding belt fixing axle 121.Therefore lever 111 is only capable of around center of gravity
Lever seat pin shaft 1122 at rotate movement.
Specifically, each belt fixing axle 121 is fixed on belt winding frame 122, and belt fixing axle 121 is belt winding
The crossbeam at 122 top of frame, pull rod 113 pass through the bottom of belt winding frame 122, and are fixed on belt by fixture nut 123 and twine
Around the bottom of frame 122, the other end of pull rod 113 is fixed on lever seat 1121, therefore when belt 121 stress of fixing axle, band
Dynamic belt winding frame 122 moves, to drive one end of lever 111 mobile by pull rod 113, so that the one of lever 111
End is tilted around center of gravity lever seat pin shaft 1122.
One end of lever 111 has v-notch 115, and the v-notch 115 is laterally disposed so that notch towards left or
The right side, the limit switch 130 connecting with driving device have elongated rod-shaped component, which is in a horizontal state, the stem
The end of part is located in v-notch 115, and the other end is fixed on frame column 151 by limit switch bracket 140.
Preferably, driving device is motor, it is circuit connection, specifically, motor and limit switch with limit switch 130
Between can be regulated and controled by PLC system, once so that limit switch 130 deviate horizontal position, then motor stops operating at once, wherein
PLC system is common PLC system, and regulation method is also regulation method common in the art.
The working principle of elevator provided by the invention is as follows: when the belt fixing axle 121 being connect with 111 both ends of lever by
When the power arrived is equal, then belt fixing axle 121 is in identical height, then lever 111 is in horizontality, therefore v-notch
115 keep horizontality, and one end of limit switch 130 is located in v-notch 115, does not contact with v-notch 115, thus
It can maintenance level state；When 121 stress of belt fixing axle connecting with 111 both ends of lever is unequal, then necessarily there is a skin
Band 121 stress of fixing axle is larger, another 121 stress of belt fixing axle is smaller, the inevitable height of two belt fixing axles 121 not phase
Together, then lever 111 necessarily has one end high and another end low, then no matter which end is high, and v-notch 115 necessarily cannot keep horizontality,
Limit switch 130 will necessarily touch any one side of v-notch 115, then limit switch 130 necessarily cannot keep horizontality,
So that motor stops operating at once.
Therefore the elevator structure of detectable balance provided by the invention is simple, can put down in elevator without manual operation
So that it is stopped working at the first time when weighing apparatus cannot control, avoids the generation of accident, reduce loss.
Obviously, those skilled in the art can carry out various modification and variations without departing from spirit of the invention to invention
And range.If these modifications and changes of the present invention is within the scope of the claims of the present invention and its equivalent technology, this
Invention is also intended to including these modification and variations.
