Abstract
The utility model discloses a correction and limit device of rigid and flexible supports of a large gantry crane, which comprises a locating rod which is fixedly connected with a girder, a deflector rod which can deflect relatively to the locating rod along with a flexible support, and a pair of microswitches which corresponds to two deflection limit positions of the deflector rod, wherein one end of the deflector rod is hinged with the flexible support, and the other end of the deflector rod is positioned between the two microswitches. An elongated locating groove is arranged at the deflector rod, and the locating rod penetrates into the locating groove. The flexible support is provided with a base, the base is fixedly connected with a support rod, and the support rod is hinged with the deflector rod through a bearing. The distance between the locating groove of the deflector rod and the microswitches is larger than that between the locating groove and a hinge part. The correction and limit device of rigid and flexible supports of the large gantry crane uses the deflector rod to magnify the deflection distance of the flexible support relative to the girder, protection signals are sent out when the deflector rod touches the microswitches, the structure is simple, the processing is convenient and the sensibility is high; and the elongated locating groove is arranged at the deflector rod, so the deflector rod is flexibly connected with the locating rod, the deflector rod is prevented from being damaged by rigid connection, and the movement is reliable.
Description
Technical field
The utility model relates to the shipbuilding technical field, is specifically related to a kind of large-sized gantry and hangs hard and soft leg correction inhibiting device.
Background technology
It is one of the main production equipments in shipbuilding yard that large-sized gantry hangs, and is the reflection of shipyard productive capacity.Large-sized gantry hangs that span is big, and hard and soft leg must guarantee parallelism in specialized range during walking, and Bureau of Technical Supervision's standard is 3 ‰.In actual the use, because track, load position, hard and soft leg operation deviation, wind direction or the like are easy to cause sideslip, the method for taking now is on hard and soft leg wheel absolute value encoder to be installed, measure the distance that hard and soft leg is advanced respectively, and send computing correction among the PLC to.But this method is a kind of method of indirect measurement after all, uneven or freeze or coder when fault is arranged when track, observed reading is inaccurate, so the correction of carrying out according to this inaccurate observed reading, can entangle more inclined to one side and more inclined to one side on the contrary, cause great potential safety hazard to equipment.Report to the police or protect when therefore needing a kind of safety device to make the gauntry crane deviation excessive and stop.
Summary of the invention
The utility model provides a kind of large-sized gantry to hang hard and soft leg correction inhibiting device at the problem that above-mentioned prior art exists, and it is simple in structure and highly sensitive.
The utility model solves the technical scheme that its technical matters adopts:.
Large-sized gantry hangs hard and soft leg correction inhibiting device, comprise the radius stay of captiveing joint with crossbeam, can follow gentle leg relative positioning bar deflection driving lever and with the cooresponding a pair of micro-switch in driving lever two tilt limit positions, driving lever one end and gentle leg are hinged, and the other end is between two micro-switchs.
Further, described driving lever has the strip shape positioning groove, and described radius stay is located in the positioning groove.
Further, described gentle leg has pedestal, and pedestal is fixedly connected with strut bar, and strut bar and driving lever pass through bearing hinge connection.
Further, described driving lever positioning groove arrives the distance of articulated section greater than positioning groove to the distance of micro-switch.
Further, described driving lever positioning groove is positioning groove 10～20 times to the articulated section distance to the distance of micro-switch.
The effect that the utility model is useful is: amplify the gentle relative crossbeam deflection distance of leg by driving lever, logical driving lever sends guard signal when touching micro-switch, and it is simple in structure, easy to process and highly sensitive; Driving lever is offered the strip shape positioning groove, and driving lever and radius stay are flexibly connected, and avoids being rigidly connected and causes driving lever to damage reliable in action.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to Fig. 1, large-sized gantry hangs hard and soft leg correction inhibiting device, comprise the radius stay 2 of captiveing joint with crossbeam 1, can follow gentle leg relative positioning bar 2 deflections driving lever 3 and with the cooresponding a pair of micro-switch 4 in driving lever two tilt limit positions, driving lever 3 one ends and gentle leg are hinged, and the other end is between two micro-switchs 4.
When the cart sideslip, gentle leg can rotate with respect to crossbeam 1, and this amount of spin is very small, through the amplification of long driving lever, promotes micro-switch 4 actions, sends guard signal.
Though the utility model illustrates and describes by the reference preferred embodiment, but those skilled in the art should understand, and can be not limited to the description of present embodiment, in the scope of claims, can do the various variation on form and the details.
