Abstract
The utility model proposes a kind of anticollision device of crane in bridge type, comprise the car limit device installed on trolley travelling track and install the master file inhibiting device on main drum axle, car limit device comprises lead limit switch and spacing lance, the setting corresponding with lead limit switch of spacing lance, master file inhibiting device is rotary stopper switch, it installs the termination, side in main drum axle, rotates with main drum axle.The utility model structure is simple, and safety performance is high, effectively avoids the generation of clashing into.
Description
Technical field
The utility model belongs to the technical field of overhead traveling crane equipment, particularly relates to a kind of anticollision device of crane in bridge type.
Background technology
Crane in bridge type is must one of obligato equipment in metallurgical production industry, after the master file system main hook of current crane in bridge type is promoted to certain altitude, restart large and small truck system normally to run, but the master file gib head of present device structure and driver operation room cannot keep corresponding rational safety distance, crane in bridge type main hook and operator's compartment may be caused to bump against, the personal safety of crane in bridge type safe operation and operator cannot be ensured.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned Problems existing; a kind of anticollision device of crane in bridge type is provided; the hidden danger that in overhead traveling crane equipment running process, master file gib head and operator's compartment collide can be eliminated; the personal safety of protection unit equipment and staff, ensures the safety in production of unit.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of anticollision device of crane in bridge type, is characterized in that, comprises the car limit device installed on trolley travelling track and installs the master file inhibiting device on main drum axle.
By such scheme, described car limit device comprises lead limit switch and spacing lance, and described lead limit switch is installed on the side trolley travelling track near operator's compartment, and described spacing lance installs position corresponding with lead limit switch on dolly.
By such scheme, described master file inhibiting device is rotary stopper switch, and the termination, side in main drum axle installed by described rotary stopper switch, rotates with main drum axle.
By such scheme, also comprise PLC, the input end of described PLC is connected with the mouth of described lead limit switch and rotary stopper switch respectively, and the mouth of PLC is connected with dolly source switch and master file system power switch respectively.
The beneficial effects of the utility model are: the anticollision device providing a kind of crane in bridge type, by crane in bridge type master file system and the moving system of the container crane crab interlocked control, when ensureing that crane in bridge type runs, master file gib head and operator's compartment have safety traffic distance, ensure the personal safety of crane in bridge type safe operation and operator.
Accompanying drawing explanation
Fig. 1 is the front elevation of the utility model embodiment.
Fig. 2 is the birds-eye view of the utility model embodiment.
Wherein: 1-operator's compartment, 2-dolly, 3-master file gib head, 4-master file reel, 5-lead limit switch, the spacing lance of 6-, 7-rotary stopper switch, 8-trolley travelling track.
Detailed description of the invention
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1-2, a kind of anticollision device of crane in bridge type, comprise the car limit device installed on trolley travelling track 8 and install the master file inhibiting device on main drum axle, car limit device comprises lead limit switch 5 and spacing lance 6, lead limit switch is installed on the side trolley travelling track near operator's compartment 1, spacing lance installs position corresponding with lead limit switch on dolly 2, spacing lance can trigger lead limit switch with trolley travelling to the position of lead limit switch, master file inhibiting device is rotary stopper switch 7, the termination, side in main drum axle installed by rotary stopper switch, rotate with main drum axle, when reaching the rotating cycle of setting, rotary stopper switch can trigger.
Also comprise PLC, the input end of PLC is connected with the mouth of lead limit switch and rotary stopper switch respectively, receive the signal that limit switch transmits, the mouth of PLC is connected with dolly source switch and master file system power switch respectively, controls the break-make of power supply.
When crane in bridge type runs, according to concrete scantling of structure, calculate the safety distance of master file gib head and operator's compartment, set the triggering of rotary stopper switch, when dolly moves to operator's compartment side, master file reel 4 rotates under the effect of steel cable, when master file gib head 3 has reached master file restraining position, trigger rotary stopper switch, trolley travelling is to dolly restraining position simultaneously, trigger lead limit switch, now, PLC sends cut-off signal respectively to dolly source switch and master file system power switch, dolly and master file system out of service, master file gib head and operator's compartment keep certain safety distance, place the generation of clashing into, when master file gib head does not reach capacity position, if now dolly reaches the limit of position, PLC can not send cut-off signal, and dolly still can continue to run to operator's compartment direction, and now master file gib head is at the lower position of driver's cab, cannot collide.
