Description
Technical field
The utility model relates to hoisting crane, is specifically related to the anti-oblique pull control setup of a kind of crane in bridge type, is a kind of control setup preventing crane in bridge type rope inclined pull hoisting object.
Background technology
Hoisting crane has clear stipulaties must not " pull and hang sideling " in hoisting operation specification, and namely hoist rope by hanging the center of gravity of thing, and will keep vertical.The harm that " pull and hang sideling " produces has: pull and hang sideling produces horizontal component of force, hangs thing when leaving ground, there will be larger swing, jeopardize the personal safety of surrounding people; Pull and hang sideling likely causes overload crane; During pull and hang sideling, steel rope rope guide easily damages, and steel rope easily falls groove disorder cable, causes parts to scrap and safety misadventure.
The existing crane in bridge type overwhelming majority does not have installation to prevent oblique drawing device, the sense of responsibility by system and operator is only had to control in operation, so usually occur because of pull and hang sideling cause that hoisting crane rope guide is scrapped, steel rope is scrapped, overload limiting device that steel rope is installed scraps, and even occurs safety misadventure.
Anti-oblique drawing device organic tool control form and automatically controlled form on existing market, Mechanical course form belongs to pressure allows steel rope and rope roll groove be consistent, and there is mechanism's complexity, cost is higher, the shortcoming that fault rate is higher.Automatically controlled form is then, after detecting steel rope angle of inclination simply, send a control signal, and controlling hoist rope must not hoist, but crane carriage and cart still can run, and can not play the object preventing oblique pull.
Summary of the invention
Technical problem to be solved in the utility model is the anti-oblique pull control setup of a kind of crane in bridge type of design, this control setup can control dolly, cart and hoist rope makes it all to the unfavorable direction motion of oblique pull, thus must not guarantee the safety of personnel and equipment.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the anti-oblique pull control setup of a kind of crane in bridge type, comprise control support body, hang at the upper top of described control support body and establish a reflecting plate, establish control circuit board in the bottom controlling reflecting plate on support body; Control circuit board is established regulator rectifier circuit, No. four photoelectric switch input circuits, signal control and amplifying circuit, six road outputting circuit for relays, and No. four photoelectric switch input circuits are connected with the input photoelectric switch in front, rear, left and right portion on control circuit board respectively; No. four photoelectric switch input circuits are connected with six road outputting circuit for relays by signal control and amplifying circuit.
Output contact on described six road outputting circuit for relays, respectively with crane in bridge type main control box internal control cart forward, cart backward, dolly left, dolly to the right, steel rope rises fast, steel rope rises at a slow speed relay is connected.
The utility model adopts the anti-oblique pull control setup of crane in bridge type designed by technique scheme, owing to being provided with reflecting plate and with regulator rectifier circuit on control support body, No. four photoelectric switch input circuits, signal control and amplifying circuit, the control circuit board of six road outputting circuit for relays, when hoisting crane oblique pull, dolly can be controlled, cart and hoist rope all must not to the unfavorable direction motions of oblique pull, the utility model does not need hand reset, install simple, reliable operation, use safety, effectively can avoid the generation of manual operation factor, guarantee that hoisting crane is operated in safe operating range.

Detailed description of the invention
Illustrate below in conjunction with the structure of accompanying drawing to the anti-oblique pull control setup of the utility model crane in bridge type.
See Fig. 1 to Fig. 3, the anti-oblique pull control setup of the utility model crane in bridge type comprises and controls support body 1, to be hung and establishes a reflecting plate 3 controlling the upper top of support body 1, establish control circuit board 2 in the bottom controlling support body 1 is positioned at reflecting plate 3 by hinge 4.Control circuit board of the present utility model is provided with regulator rectifier circuit, No. four photoelectric switch input circuits, signal control and amplifying circuit, six road outputting circuit for relays.Regulator rectifier circuit is the DC constant voltage power supply needed for 24 ~ 36V/50Hz source of AC conversion cost utility model control setup work of input.On control circuit board 2, front, rear, left and right portion establishes input photoelectric switch 5, No. four photoelectric switch input circuit to be the break-make being controlled photoelectric switch 5 by the reflecting plate 3 be arranged on above photoelectric switch 5.The incoming signal of signal control and amplifying circuit Shi Ba No. tetra-photoelectric switch amplifies the rear action exporting and then control output relay.Six road outputting circuit for relays are that handle is through photoelectric switch input circuit, and the signal after signal control and amplifying circuit inputs six road outputting circuit for relays, perform corresponding relay output action, export with control when meeting crane in bridge type wire rope inclined-pulling.The output contact of No. six relays, access respectively cart in crane in bridge type main control box forward, cart backward, dolly left, dolly to the right, steel rope rises fast, steel rope rises at a slow speed relay, play the effect that angular travel is spacing, to reach the object of safety control when controlling crane in bridge type wire rope inclined-pulling.
During use, the utility model is fixed on crane in bridge type hoisting wirerope 6 by fixing card 7.Under normal circumstances, the steel rope 6 of crane in bridge type there will not be oblique pull, weight 12 on ground 11 is under the effect of winch 10, be lifted by steel rope 6, the position of movement as required, by control cart 8 move forward, backward, then by control dolly 9 left, move right, make lifted weight thing move to suitable position.When there is steel rope 6 oblique pull certain angle in crane in bridge type lifting, control setup of the present utility model tilts along with steel rope 6 and tilts, now, reflecting plate 3 blocks the photoelectric switch 5 of a direction, make photoelectric switch 5 conducting in this direction, the signal of photoelectric switch input circuit after signal control and amplifying circuit in this direction inputs the corresponding output circuit of No. six relay, perform corresponding relay output action, hoist rope to the unfavorable direction motion of oblique pull, must not be exported with control when meeting crane in bridge type wire rope inclined-pulling.
