The following describes a mechanism for detecting stable lifting of a steel cable according to some embodiments of the present invention with reference to the accompanying drawings.

The first embodiment is as follows: referring to fig. 2 and 5, the mechanism for detecting stable lifting of a steel wire rope provided by the utility model comprises a coding control part and a tension sensing part, wherein the coding control part comprises a hollow encoder bracket 4, a hollow encoder 1, a fixed bracket 2, an inner hexagonal socket head cap screw 3, a fixed block 5 and a cross recessed pan head screw 6, the fixed bracket 2 is sleeved outside the hollow encoder 1, the inner hexagonal socket head cap screw 3 is installed in the fixed bracket 2, the hollow encoder bracket 4 is installed on the hollow encoder 1, the fixed block 5 is positioned at one side of the fixed bracket 2, the cross recessed pan head screw 6 penetrates through the outside of the fixed bracket 2 and is connected with the fixed block 5, the number of the cross recessed pan head cap screws 6 is one group, the cross recessed pan head screws 6 are provided with flat spring pads, the number of the inner hexagonal socket head cap screws 3 is two, and the two inner hexagonal socket head cap screws 3 are both provided with corresponding spring pad nuts, hollow encoder support 4 is connected with the motor for with hollow encoder 1 and motor axle center adaptation installation and fixed, the mutual adaptation of hole of two hexagon socket head cap screws 3 in fixed bolster 2, be used for hollow encoder 1 stability outside the motor, the code control portion is used for presetting numerical value through hollow encoder 1 and realizes the hoist engine to the control of wire rope height-lifting.

2 buckles of fixed bolster 2 are in hollow encoder 1's outside to utilize hexagonal socket head cap screw 3 to run through to fixed bolster 2 in, utilize hexagonal socket head cap screw 3 to carry out the monolithic stationary phase with fixed bolster 2 and hollow encoder 1, install hollow encoder 1 adaptation on equipment through hollow encoder support 4 simultaneously, then utilize cross recess pan head screw 6 to run through to the support outside and connect in the outer end of fixed block 5, fixed bolster 2 can be whole parcel hollow encoder 1 in some embodiments, so as to reduce hollow encoder 1 impaired when using.

Specifically, the tension sensing part comprises a tension sensor 7, the tension sensing part is used for controlling the winch to allow, stop and give an alarm on the descending action of the steel wire rope by using a tension feedback value of the tension sensor 7, one end of the tension sensor 7 is connected to the steel wire rope, the bottom end of the tension sensor 7 is installed on a tray for bearing a heavy object, and in some embodiments, a plurality of tension sensors 7 can be arranged on the tray for bearing the heavy object and used for transmitting weight data of the object to a plc and accurately controlling the steel wire rope.

Example two: in the above embodiment, shown in fig. 4, the hollow encoder bracket 4 is made of Q235 color-plated zinc, in some embodiments, the hollow encoder bracket 4 may be 304 stainless steel, and the approach switch, the photoelectric switch, the encoder, etc. are sequentially used, and the approach switch can only detect the next point, so if the descending position is more and the height is different, more approach switches are needed, and the detection distance of the proximity switch is short, the detection error is easy to occur, when the device is used, the winch of the existing device controls the steel wire rope to descend indefinitely when the winch directly lifts, obliquely pulls or translates the heavy object, in some embodiments, the winch is required to pull the steel wire rope for fine adjustment when the heavy object is received, more approach lights are required for frequently adjusting the height and the position of the heavy object, and the approach light detection easily causes the multi-directional detection error of the heavy object in the heavy object pulling process.

Example three: referring to fig. 1 and 4, in the above embodiment, the approach switch, the photoelectric switch, the encoder and the like are used successively, although the detection distance of the photoelectric switch is long, the requirement on the detection surface is high, and the false detection condition is easy to occur.
