Abstract
The invention discloses a gantry crane steel wire rope detection device, which belongs to the field of safe devices of a container truck and a sling in the container loading and unloading operations. The gantry crane steel wire rope detection device comprises a pulley block, a sling, a towing bracket, towing bracket locks, contact switches, a wireless communication module, a wireless receiving module and a pulley brake gear, wherein the towing bracket locks on two ends of the towing bracket are provided with the contact switches; a circuit is connected to the wireless communication module; the pulley block is provided with the pulley brake gear controlled by the circuit; the circuit is connected with the wireless receiving module; and the signal of the wireless communication module is received by the wireless receiving module. When the towing bracket locks are locked, the contact switches are connected, and the wireless communication module sends the signal to the wireless receiving module; and the pulley brake gear is controlled as an on state by the wireless receiving module to prevent the pulley block from continuously lowering. In the working process, the crane can be forced from lowering to prompt to unlock the towing bracket locks, and a headstock or a car body can be prevented from being hoisted with the container to avoid accidents.
Description
Technical field
The present invention relates to the safe operation of container truck and suspender in the container handling operation, specifically the gantry crane testing device for wire ropes.
Background technology
When at present the place container gantry was hung in destuff, trailer driver was forgotten sometimes the bracket lock is opened, and causes headstock or vehicle body to be sling together with freight container, is prone to accidents caused.Also there is not the actv. detection means at present.
Summary of the invention
In view of the defective that prior art exists, the present invention provides the gantry crane testing device for wire ropes, and the prompting trailer driver is opened the bracket lock, prevents that headstock or vehicle body from being sling together with freight container.
For realizing above-mentioned purpose, the technical scheme that the present invention adopted is the gantry crane testing device for wire ropes, comprises assembly pulley, suspender, bracket, also comprises bracket lock, touch switch, wireless communication module, wireless receiving module, pulley brake gear; Bracket lock on the bracket two ends is installed touch switch, and circuit is connected to wireless communication module, and the pulley brake gear is installed on the assembly pulley again, and by circuit control, circuit connects wireless receiving module, and the signal of wireless communication module is received by wireless receiving module.When described bracket lock is locked, touch switch circuit UNICOM, wireless communication module sends signal to wireless receiving module, and the pulley brake gear is controlled to be on-state by wireless receiving module, stops the continuation down maneuver of assembly pulley; When the bracket lock was opened, touch switch broke off, and wireless communication module no longer sends signal to wireless receiving module, and wireless receiving module control pulley brake gear is a closed condition, and crane freely lifts freight container.The active distance of the signal transmission between wireless communication module and the wireless receiving module can be set, and optimum distance is that suspender gets in 5 meters scopes of bracket.
After adopting such scheme, compared with prior art have following beneficial effect: the present invention forces to stop the down maneuver of crane in the course of the work, and the bracket lock is opened in prompting, prevents that headstock or vehicle body from being sling together with freight container, and is accidents caused.
Description of drawings
Fig. 1 is a kind of structural representation of gantry crane testing device for wire ropes.
Among the figure: 1, bracket lock, 2, touch switch, 3, wireless communication module, 4, wireless receiving module, 5, the pulley brake gear, 6, assembly pulley.
The specific embodiment
In the scheme drawing of gantry crane testing device for wire ropes shown in Figure 1, comprise assembly pulley 6, suspender, bracket, bracket lock 1, touch switch 2, wireless communication module 3, wireless receiving module 4, pulley brake gear 5; Bracket lock 1 on the bracket is installed touch switch 2; Circuit is connected to wireless communication module 3, and pulley brake gear 5 is installed on the assembly pulley 6 again, is controlled by circuit; Circuit connects wireless receiving module 4, and the signal of wireless communication module 3 is received by wireless receiving module 4.When bracket lock 1 is not opened; Described touch switch 2 UNICOMs, wireless communication module 3 sends signals to wireless receiving module 4, and pulley brake gear 5 is controlled to be on-state by wireless receiving module 4; The continuation down maneuver that stops assembly pulley 6, the prompting trailer driver is opened bracket lock 1; When bracket lock 1 was opened, described touch switch 2 broke off, and wireless communication module 3 no longer sends signal to wireless receiving module 4, and wireless receiving module control pulley brake gear 5 is a closed condition, and crane freely lifts freight container.The distance that signal between wireless communication module 3 and the wireless receiving module 4 is transmitted in suspender and bracket is to work in 5 meters the time.In the course of the work, force to stop the down maneuver of crane, the bracket lock is opened in prompting, prevents that headstock or vehicle body from being sling together with freight container, and is accidents caused.
