Abstract
A gantry crane wire rope detection device belongs to the field of container truck and suspender safety devices in the loading and unloading operation of containers. The gantry crane wire rope detection device contains an assembly pulley, a suspender, a bracket, bracket locks, touch switches, a wireless communication module, a wireless receiving module and a pulley brake device. The touch switches are installed on the bracket locks on two ends of the bracket. A circuit is connected to the wireless communication module. The pulley brake device is installed on the assembly pulley and is controlled by the circuit, which is connected to the wireless receiving module. Signals are received by the wireless receiving module from the wireless communication module. When the bracket locks are locked, the touch switch circuit is connected, the wireless communication module sends signals to the wireless receiving module, and the wireless receiving module controls the pulley brake device to be a turn-on state so as to prevent the assembly pulley from continuously descending. During the operation process, a crane is forced to stop descending and the bracket locks are prompted to open, thus preventing a headstock or body from being hoisted together with a container and avoiding accidents.
Description
Technical field
The utility model relates to the safe operation of container truck and suspender in the container handling operation, gantry crane testing device for wire ropes specifically.
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 utility model 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 utility model 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 utility model 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, the bracket lock 1 on the bracket is installed touch switch 2, and circuit is connected to wireless communication module 3; Pulley brake gear 5 is installed on the assembly pulley 6 again; By circuit control, 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.
