Description
Technical field
The present invention relates to hoisting control device field, particularly relate to a kind of conversion equipment rotated for crane gear suspension hook with stop.
Background technology
When current steel mill is in the middle of handling, suspension hook can not rotate, when all the other, can rotate freely again, thus require this suspension hook reliably should position at ad-hoc location, only (turning) dynamic, switching rapidly again, recover to rotate, common suspension hook stop and rotation measures mainly have so three kinds:
One is in the both sides groove milling of suspension hook shank, then pitches with jaw clamp and carry out stop in groove, and after extracting fork plate, suspension hook just can rotate, and the shortcoming of this method is: the bearing capacity of suspension hook is had a certain impact; When operation, it is necessary to by platform, carry out dismounting clamp and bolt thereof, for needing often to rotate and the suspension hook of stop conversion, inapplicable.
Two is at the rotation of hook assembly, standing part, respectively welds screw bolt seat, when needs stop, screw rod, nut of screwing on string, when needs rotate, take off screw rod. The shortcoming of this mode is: during operation, it has not been convenient to, conversion speed is slow.
Three is adopt electric rotary locating hook, suspension hook is directly driven to rotate by a motor, reductor, brake " three-in-one " driving device, being walked around hook nut by a steel wire rope or (nylon rope) again drives a wheel disc to realize synchronous axial system, control wheel dish rotational angle is carried out by the effect of proximity switch with the sensing chip being arranged on wheel disc, and then control the suspension hook anglec of rotation, the shortcoming of this method is: structure is more complicated, relatively costly, and practicality is not strong.
Summary of the invention
The technical problem to be solved is to provide a kind of conversion equipment rotated with stop for crane gear suspension hook, there is making compared with mechanism originally simple, with low cost, it is easy to accomplish, suspension hook stop para-position more accurately, conveniently, switches the advantages such as safer, reliable.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of conversion equipment rotated with stop for crane gear suspension hook, including upper stop-motion seat, lower stop-motion seat, stop gib head and hook assembly, the described bottom surface of upper stop-motion seat is connected with the side surface upper part of hook assembly, described lower stop-motion seat has two pieces, be mounted side by side on hook assembly side, below upper stop-motion seat, the lower end of described stop gib head is rotatably connected between lower stop-motion seat.
The lateral surface of described upper stop-motion seat has groove, and the upper end of this groove size and stop gib head matches.
Described lower stop-motion seat is polygon tabular, manhole it is provided with in the middle part of it, its top is provided with the spill through hole being directed downward, the connection bump that one side side arrangement that it is connected with hook assembly has cross section to be isosceles trapezoid, described connection bump embeds and is weldingly fixed in hook assembly side.
The described L-shaped tabular of stop gib head, the lateral projection of the upper end of this stop gib head is embedded in stop-motion seat, and its lower end is provided with circular fixation hole, described circular fixation hole be arranged above oval fixing hole.
Described lower stop-motion seat is rotationally connected by bearing pin traverse manhole and circular fixation hole and stop gib head, when being in arrested state, described lower stop-motion seat passes through bearing pin and positions with stop gib head near one end of hook assembly and oval fixing hole through spill through hole, and bearing pin and spill through hole block fixing;
When being in rotation status, described lower stop-motion seat is by the lateral ends of bearing pin traverse spill through hole and oval fixing hole and stop gib head location, and bearing pin and spill through hole block fixing, and stop gib head is in the state departed from upper stop-motion seat.
Beneficial effect
The present invention relates to a kind of conversion equipment rotated with stop for crane gear suspension hook, this device solves the conversion that suspension hook positions on a certain ad-hoc location and rotates targetedly, there is making compared with mechanism originally simple, with low cost, it is easily achieved, suspension hook stop para-position more accurately, conveniently, switches the advantages such as safer, reliable.
