Abstract
The utility model provides a communication cable anti-snapping device for a gantry crane. The device comprises a base plate, two arc guide plates, a cable baffle, a cable pressure plate and a limit switch, wherein the base plate is arranged at the side of the gantry crane; the two arc guide plates are symmetrically arranged at one side of the lower part of the base plate in a trumpet shape, and the small opening side is positioned on the base plate facing to the external side; the cable baffle is pressed on the large opening side of the two arc guide plates which are arranged in a trumpet shape, and is fixedly connected with the base plate; the cable pressure plate is pressed on the small opening side of the two arc guide plates which are arranged in a trumpet shape, and is fixedly connected with the base plate; a groove which is used for the cable to penetrate through is formed at the middle lower part of the cable pressure plate; the limit switch is arranged at the upper part of the base plate, and is positioned above the two arc guide plates; and an output end of the limit switch is connected with a main hook rising limit circuit of the gantry crane in series. By the device, the phenomenon that a hook rising cable is snapped when the hook rising cable is tensioned is effectively prevented.
Description
Technical field
The utility model relates to gauntry crane traverse crane equipment, particularly the anti-breaking device of a kind of gauntry crane suspender communication cable.
Background technology
In the epoch that logistlcs technology develops rapidly, the automation of hoisting appliance is own through becoming the indispensable basic tool of modern logistics.Oneself is widely used in harbour gauntry crane traverse crane equipment, railway, power plant, metallurgy, the industries such as grain.
Now along with the adjustment of production structure, the operation of handling corrosion-resistant steel roll bending becomes normality work, thereby by having filled electric fixture and rotary lifting hook device improves working out, by control cables anchor clamps and shackle hook is carried out the Power supply and control signal simultaneously and transmits.
Because control cables is along with suspension hook moves up and down.The cable operation is along with cable drum and cable drum carry out synchronously.But when suspension hook rose to top, the cable number of plies increase of cable drum volume also just caused the phenomenon of directly breaking after strengthening (linear velocity increase), can causing cable to be tightened up.
Summary of the invention
The purpose of this utility model designs the anti-breaking device of a kind of gauntry crane suspender communication cable, can effectively prevent the phenomenon of breaking after the suspension hook rise cable is tightened up.
For achieving the above object, the technical solution of the utility model is:
A kind of gauntry crane suspender communication cable is prevented breaking device, and it comprises, base plate is installed on gauntry crane suspender side; Two arc-shaped guide plates are symmetricly set in base plate bottom one side, are horn-like layout, and the osculum side is positioned on the base plate in the outer part direction; The cable baffle plate is installed with in two arc-shaped guide plates and is in the large mouthful side place of horn-like layout, is connected and fixed with base plate; Cable pressing plate is installed with in two arc-shaped guide plates and is in the osculum side place of horn-like layout, is connected and fixed with base plate, and the cable pressing plate central lower is offered the groove that current supply cable passes; Limit switch is arranged at base plate top, is positioned at the top of two arc-shaped guide plates, and the limit switch mouth is series at gauntry crane suspender main hook lifting position-limit circuit.
Further, corresponding described limit switch is also established a cable seesaw, and the one end is movably connected on the base plate, and the cable seesaw can guarantee effectively that cable touches limit switch after being tightened up.
It is arc groove that described cable pressing plate central lower is offered the groove that current supply cable passes.
Cable is that free pine is executed state from cable drum to suspension hook bearing during normal operation; When suspension hook and cable rise near the top, tighten up cable through increasing and touch the limit switch suspension hook that stops owing to cable on the cable drum batches directly, the protection cable is damaged because of tension.
The beneficial effects of the utility model:
After the utility model was used, after suspension hook handling object rose to cable tension height, main hook just can not rise again, and whether the anti-breaking device of cable works limit switch prompting operation worker, thereby guarantees that cable is not broken.Reduce the cable mal and damaged, also saved a large amount of repair times simultaneously, reduced the maintenance downtime of equipment.
Description of drawings
Fig. 1 is the cable structural representation in the raw of the utility model embodiment.
Fig. 2 is the structural representation that the cable of the utility model embodiment is in tension.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of gauntry crane suspender communication cable of the present utility model is prevented breaking device, and it comprises, base plate 1 is installed on gauntry crane suspender side; Two arc-shaped guide plates 2,2 ' are symmetricly set in base plate 1 bottom one side, are horn-like layout, and the osculum side is positioned on the base plate in the outer part direction; Cable baffle plate 3 is installed with in two arc-shaped guide plates 2,2 ' and is in the large mouthful side place of horn-like layout, is connected and fixed with base plate 1; Cable pressing plate 4 is installed with in two arc-shaped guide plates 2,2 ' and is in the osculum side place of horn-like layout, is connected and fixed with base plate 1, and cable pressing plate 4 central lower are offered the groove 41 that current supply cable passes; Limit switch 5 is arranged at base plate 1 top, is positioned at two arc-shaped guide plates 2,2 ' top, and the limit switch mouth is series at gauntry crane suspender main hook lifting position-limit circuit.
Further, corresponding described limit switch 5 is also established a cable seesaw 6, and the one end is movably connected on the base plate 1.Cable leans cable seesaw 6 when rising, and touches limit switch 5, provides limit signal.
Described cable pressing plate 4 central lower are offered the groove 41 that current supply cable 100 passes and are arc groove.
Cable is that free pine is executed state from cable drum to suspension hook bearing during normal operation, as shown in Figure 1; When suspension hook and cable rise near the top, tighten up cable through increasing and touch the limit switch suspension hook that stops owing to cable on the cable drum batches directly, the protection cable is damaged because of tension, as shown in Figure 2.
